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

     (e) The Company may set any date as a record date for the purpose of determining the Holders of Outstanding Purchase Contracts 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 Purchase Contracts. If any record date is set pursuant to this paragraph, the Holders of the Outstanding Purchase Contracts on such record date, and no other Holders, shall be entitled to take the relevant action with respect to the Purchase Contracts, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken prior to or on the applicable expiration date by Holders of the requisite number of Outstanding Purchase Contracts 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 Purchase Contracts 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 Purchase Contracts in the manner set forth in Section 1.06.

     With respect to any record date set pursuant to this Section, the Company may designate any date as the “expiration date” and from time to time may change the expiration date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new expiration date is given to the Purchase Contract Agent in writing, and to each Holder of Purchase Contracts in the manner set forth in Section 1.06, prior to or on the existing expiration date. If an expiration date is not designated with respect to any record date set pursuant to this Section, the Company shall be deemed to have initially designated the 180th day after such record date as the expiration date with respect thereto, subject to its right to change the expiration date as provided in this paragraph. Notwithstanding the foregoing, no expiration date shall be later than the 180th day after the applicable record date.

     Section 1.05. Notices. Any notice 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 courier guaranteeing next day delivery, to the others’ address; provided that notice shall be deemed given to the Purchase Contract Agent only upon receipt thereof:

     Section 1.06. Notice to Holders; Waiver. Where this Agreement provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at its address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Agreement provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Purchase Contract Agent, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

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

     Section 1.07. Effect of Headings and Table of Contents. The Article and Section headings herein and in the Table of Contents are for convenience only and shall not affect the construction hereof.

     Section 1.08. Successors and Assigns. All covenants and agreements in this Agreement by the Company and the Purchase Contract Agent shall bind their respective successors and assigns, whether so expressed or not.

     Section 1.09. Separability Clause. In case any provision in this Agreement or in the Purchase Contracts shall be invalid, illegal or unenforceable, the validity, legality and

enforceability of the remaining provisions hereof and thereof shall not in any way be affected or impaired thereby.

     Section 1.10. Benefits of Agreement. Nothing contained in this Agreement or in the Purchase Contracts, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and, to the extent provided hereby, the Holders, any benefits or any legal or equitable right, remedy or claim under this Agreement. The Holders from time to time shall be beneficiaries of this Agreement and shall be bound by all of the terms and conditions hereof and of the Purchase Contracts by their acceptance of delivery of such Purchase Contracts.

     Section 1.11. Governing Law. This Agreement, the Units and the Purchase Contracts, and any claim, controversy or dispute arising under or related to this Agreement, the Units or the Purchase Contracts, shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to the conflicts of laws provisions thereof.

     Section 1.12. Judicial Proceedings. (a) Each of the Company and the Purchase Contract Agent expressly accepts and irrevocably submits to the non-exclusive jurisdiction of the United States Federal or New York State court sitting in the Borough of Manhattan, The City of New York, New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Purchase Contracts. To the fullest extent it may effectively do so under applicable law, each of the Company and the Purchase Contract Agent irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

     (b) Each of the Company and the Purchase Contract Agent agrees, to the fullest extent that it may effectively do so under applicable law, that a judgment in any suit, action or proceeding of the nature referred to in Section 1.12(a) brought in any such court shall be conclusive and binding upon such party, subject to rights of appeal, and may be enforced in the courts of the United States of America or the State of New York (or any other court the jurisdiction to which the Company is or may be subject) by a suit upon such judgment.

     (c) Nothing in this Section 1.12 shall affect the right of any party hereto to serve process in any manner permitted by law, or limit any right to bring proceedings against any other party hereto in the courts of any jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

     Section 1.13. Legal Holidays. In any case where any Mandatory Settlement Date, Early Settlement Date, Early Mandatory Settlement Date or Fundamental Change Early Settlement Date shall not be a Business Day, notwithstanding any other provision of this Agreement or the Purchase Contracts, settlement of the Purchase Contracts shall not be effected on such date, but instead shall be effected on the next succeeding Business Day with the same force and effect as if made on such Mandatory Settlement Date, Early Settlement Date, Early Mandatory Settlement

Date or, Fundamental Change Early Settlement Date, as applicable, and no interest or other amounts shall accrue or be payable by the Company or to any Holder in respect of such delay, except that, if such next succeeding Business Day is in the next succeeding calendar year, such settlement shall be made on the immediately preceding Business Day with the same force and effect as if made on such Mandatory Settlement Date, Early Settlement Date, Early Mandatory Settlement Date or Fundamental Change Early Settlement Date, as applicable.

     Section 1.14. Counterparts. This Agreement may be executed in any number of counterparts by the parties hereto on separate counterparts, each of which, when so executed and delivered, shall be deemed an original, but all such counterparts shall together constitute one and the same instrument.

     Section 1.15. Inspection of Agreement. A copy of this Agreement shall be available at all reasonable times during normal business hours at the Corporate Trust Office for inspection by any Holder or Beneficial Owner.

     Section 1.16. Waiver of Jury Trial. EACH OF THE COMPANY, THE PURCHASE CONTRACT AGENT AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

     Section 1.17. Force Majeure. In no event shall either of the Purchase Contract Agent or the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that each of the Purchase Contract Agent and the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

     Section 1.18. Calculations. The solicitation of any necessary bids and calculations to be made hereunder shall be the obligation of the Company. These calculations include, but are not limited to, determination of the applicable Settlement Rate, the Fixed Settlement Rates, the Early Settlement Rate, the Early Mandatory Settlement Rate, the Fundamental Change Early Settlement Rate, the Applicable Market Value, the Daily VWAP and the VWAP, as the case may be. All calculations made by the Company or its agent as contemplated pursuant to the terms hereof shall be made in good faith and, absent manifest error, be final and binding on the Purchase Contract Agent, the Trustee, each Paying Agent and on the Holders. For any calculations to be made by the Company or its agent as contemplated pursuant to the terms hereof, the Company shall provide a schedule of such calculations to the Purchase Contract Agent and the Trustee, and each of the Purchase Contract Agent and the Trustee shall be entitled to conclusively rely upon the accuracy of the calculations by the Company or its agent without independent verification, shall have no liability with respect thereto and shall have no liability to

the Holders for any loss any of them may incur in connection with no independent verification having been done.

     Section 1.19. UCC. Each Purchase Contract (whether or not included in a Unit) is a security governed by Article 8 of the Uniform Commercial Code as in effect in the State of New York on the date hereof.

ARTICLE 2
Unit and Purchase Contract Forms

     Section 2.01. Forms of Units and Purchase Contracts Generally. The Units and Purchase Contracts shall be in substantially the forms set forth in Exhibit A and Exhibit B hereto, respectively, which shall be incorporated in and made a part of this Purchase Contract Agreement, 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 Units or Purchase Contracts, as the case may be, are (or may in the future be) listed or any depositary therefor, or as may, consistently herewith, be determined by the officers of the Company executing such Units and Purchase Contracts, as the case may be, as evidenced by their execution thereof.

     The Units and Purchase Contracts shall be issuable only in registered form and only in denominations of a single Unit or Purchase Contract, as the case may be, and any integral multiple thereof.

     Definitive Securities shall be printed, lithographed or engraved with steel engraved borders or may be produced in any other manner, all as determined by the officers of the Company executing the Units or Purchase Contracts, as the case may be, evidenced by such Definitive Securities, consistent with the provisions of this Agreement, as evidenced by their execution thereof.

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

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

DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY) MAY BE REGISTERED EXCEPT IN LIMITED CIRCUMSTANCES.

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

     Section 2.02. Form of Purchase Contract Agent’s Certificate of Authentication. The form of the Purchase Contract Agent’s certificate of authentication of the Units and Purchase Contracts shall be in substantially the form set forth in the form of Unit or form of Purchase Contract, respectively, attached hereto.

     Section 2.03. Global Securities; Separation of Units. (a) On any Business Day during the period beginning on, and including, the Business Day immediately succeeding the date of this Agreement to, but excluding, the third Business Day immediately preceding the Mandatory Settlement Date, a Holder or Beneficial Owner of a Unit may separate such Unit into its constituent Purchase Contract and Note (each such separated Purchase Contract and separated Note, a “Separate Purchase Contract” and “Separate Note,” respectively), which will thereafter trade under their respective CUSIP numbers (172967 390) and (172967 FB2), and that Unit will cease to exist. Beneficial interests in a Unit, and after separation, the Separate Purchase Contract and Separate Note, will be shown on and transfers will be effected through direct or indirect participants in DTC. Beneficial interests in Units, Separate Purchase Contracts and Separate Notes will be evidenced by Global Units, Global Purchase Contracts and Global Notes, respectively. In order to separate a Unit into its component parts, a Beneficial Owner must deliver written instruction to the broker or other direct or indirect participant (the “Participant”) through which it holds an interest in such Unit to notify DTC through DTC’s Deposit/Withdrawal at Custodian System (the “DWAC System”) of such Beneficial Owner’s election to separate such Unit, unless such Unit is in the form of a Definitive Security, in which case the Holder thereof must deliver to the Purchase Contract Agent such Unit, together with a separation notice, in the form set forth in Attachment 1 to the form of Unit attached hereto as Exhibit A. Upon the receipt of such separation notice, the Company shall promptly cause delivery, in accordance with the delivery instructions set forth in such separation notice, of one Separate Purchase Contract and one Note for each such Unit. Separate Purchase Contracts and Separate Notes will be transferable independently from each other.

     (b) Holders which elect to separate the Note and related Purchase Contract in accordance with this Section 2.03 shall be responsible for any fees or expenses payable in

connection with such separation, and the Company shall not be responsible for any such fees or expenses.

     Section 2.04. Recreation of Units. (a) On any Business Day during the period beginning on, and including, the Business Day immediately succeeding the date of this Agreement to, but excluding, the third Business Day immediately preceding the Mandatory Settlement Date, a Holder or Beneficial Owner of a Separate Purchase Contract and a Separate Note may recreate a Unit (which will thereafter trade under the CUSIP number for the Units (172967 416)), and each such Separate Purchase Contract and Separate Note will cease to exist. In order to recreate a Separate Purchase Contract and Separate Note into a Unit, a Beneficial Owner must deliver written instruction to the Participant through which it holds an interest in such Separate Purchase Contract and Separate Note and to notify DTC through DTC’s DWAC System of such Beneficial Owner’s election to recreate a Unit, unless such Separate Purchase Contract and Separate Note are in the form of Definitive Securities, in which case the Holder thereof must deliver to the Purchase Contract Agent such Definitive Securities, together with a recreation notice, in the form set forth in Attachment 2 to the form of Unit attached hereto as Exhibit A. Upon the receipt of such recreation notice, the Company shall promptly cause delivery, in accordance with the delivery instructions set forth in such recreation notice, of one Unit in definitive form for such Definitive Securities.

     (b) Holders that recreate Units in accordance with this Section 2.04 shall be responsible for any fees or expenses payable in connection with such recreation, and the Company shall not be responsible for any such fees or expenses.

ARTICLE 3
The Units and Purchase Contracts

     Section 3.01. Amount and Denominations. The aggregate number of Units and Separate Purchase Contracts evidenced by Equity-Linked Securities authenticated, executed on behalf of the Holders and delivered hereunder is limited to 35,000,000, except for Units and Separate Purchase Contracts authenticated, executed and delivered upon registration or transfer of, in exchange for, or in lieu of, other Units and Separate Purchase Contracts pursuant to Section 3.04, 3.05, 3.10 or 8.05.

     Equity-Linked Securities that are not in the form of Global Securities shall be issuable in denominations of one Equity-Linked Security and integral multiples in excess thereof

     Section 3.02. Rights and Obligations Evidenced by the Equity-Linked Securities. Each Equity-Linked Security shall evidence the number of Units or Separate Purchase Contracts, as the case may be, specified therein, with each such Unit and each such Separate Purchase Contract representing the rights and obligations of the Holder thereof and the Company under one Unit or one Separate Purchase Contract, respectively.

     Prior to the delivery of shares of Common Stock under each Purchase Contract (whether such Purchase Contract is held as a component of a Unit or as a Separate Purchase Contract), such Purchase Contract shall not entitle the Holder thereof to any of the rights of a holder of Common Stock, including, without limitation, the right to vote or receive any dividends or other payments or to consent or to receive notice as a shareholder in respect of the meetings of shareholders or for the election of directors for any other matter, or any other rights whatsoever as a shareholder of the Company.

     Section 3.03. Execution, Authentication, Delivery and Dating. Upon the execution and delivery of this Agreement, and at any time and from time to time thereafter, the Company may deliver Equity-Linked Securities executed by the Company to the Purchase Contract Agent for authentication, execution on behalf of the Holders and delivery, together with the Issuer Order for authentication of such Equity-Linked Securities, and the Purchase Contract Agent in accordance with such Issuer Order shall authenticate, execute on behalf of the Holders and deliver such Equity-Linked Securities.

     The Equity-Linked Securities shall be executed on behalf of the Company by any authorized officer of the Company. The signature of any such officer on the Equity-Linked Securities may be manual or facsimile.

     Equity-Linked Securities bearing the manual or facsimile signature of an individual who was at any time the proper officer of the Company shall bind the Company, notwithstanding that such individual has ceased to hold such offices prior to the authentication and delivery of such Equity-Linked Securities or did not hold such offices at the date of such Equity-Linked Securities.

     Each Equity-Linked Security shall be dated the date of its authentication.

     No Equity-Linked Security shall be entitled to any benefit under this Agreement or be valid or obligatory for any purpose unless there appears on such Equity-Linked Security 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 Equity-Linked Security shall be conclusive evidence, and the only evidence, that such Equity-Linked Security has been duly authenticated and delivered hereunder.

     Section 3.04. Temporary Equity-Linked Securities. Pending the preparation of Definitive Equity-Linked Securities, 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 Equity-Linked Securities, temporary Equity-Linked Securities that are in substantially the form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters, numbers or other marks of identification or designation and such legends or endorsements printed, lithographed or engraved thereon as may be required by the rules of any securities exchange on which the Units or Separate Purchase Contracts, as the case may be, are listed, or as may, consistently herewith, be determined by the officers of the Company executing such Equity-Linked Securities, as evidenced by their execution of the Equity-Linked Securities.

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

     Section 3.05. Registration; Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office a register (the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Equity-Linked Securities and of transfers of Equity-Linked Securities. The Purchase Contract Agent is hereby initially appointed Security Registrar (the “Security Registrar”) for the purpose of registration of Equity-Linked Securities and transfers of Equity-Linked Securities as provided herein. The Security Registrar shall record separately the registration and transfer of the Equity-Linked Securities evidencing Units and Separate Purchase Contracts.

     Upon surrender for registration of transfer of any Equity-Linked Security 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 Equity-Linked Securities of any authorized denominations, of like tenor, and evidencing a like number of Units or Separate Purchase Contracts, as the case may be.

     At the option of the Holder, Equity-Linked Securities may be exchanged for other Equity-Linked Securities, of any authorized denominations and evidencing a like number of Units or Separate Purchase Contracts, as the case may be, upon surrender of the Equity-Linked Securities to be exchanged at the Corporate Trust Office. Whenever any Equity-Linked Securities 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 Equity-Linked Securities which the Holder making the exchange is entitled to receive.

     All Equity-Linked Securities issued upon any registration of transfer or exchange of an Equity-Linked Security shall evidence the ownership of the same number of Units or Separate Purchase Contracts, as the case may be, and be entitled to the same benefits and subject to the same obligations, under this Agreement as the Units or Separate Purchase Contracts, as the case

may be, evidenced by the Equity-Linked Security surrendered upon such registration of transfer or exchange.

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

     No service charge shall be made for any registration of transfer or exchange of an Equity-Linked Security, but the Company 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 Equity-Linked Securities, other than any exchanges pursuant to Section 3.06 and Section 8.05 not involving any transfer.

     Notwithstanding the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall not be obligated to authenticate, execute on behalf of the Holder or deliver any Equity-Linked Security in exchange for any other Equity-Linked Security presented or surrendered for registration of transfer or for exchange on or after the Business Day immediately preceding the earliest of the Mandatory Settlement Date, any Early Settlement Date, any Early Mandatory Settlement Date or any Fundamental Change Early Settlement Date with respect to such Equity-Linked Security. In lieu of delivery of a new Equity-Linked Security, 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, if the Mandatory Settlement Date, any Early Settlement Date, any Early Mandatory Settlement Date or any Fundamental Change Early Settlement Date shall have occurred with respect to such Equity-Linked Security, deliver the shares of Common Stock deliverable in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with the Separate Note, if such Equity-Linked Security is a Unit).

     Section 3.06. Book-Entry Interests. The Units, on original issuance, will be issued in the form of one or more fully registered Global Units, to be delivered to the Depositary or its custodian by, or on behalf of, the Company. The Company hereby designates DTC as the initial Depositary. Such Global Units shall initially be registered on the books and records of the Company in the name of Cede & Co., the nominee of DTC, and no Beneficial Owner will receive a Definitive Unit representing such Beneficial Owner’s interest in such Global Unit, except as provided in Section 3.09. The Purchase Contract Agent shall enter into an agreement with the Depositary if so requested by the Company in writing. Unless and until definitive, fully registered Securities have been issued to Beneficial Owners pursuant to Section 3.09:

          (i) the provisions of this Section 3.09 shall be in full force and effect;

     (ii) except as contemplated in the definition of “Holders” in Section 1.01(d), the Company shall be entitled to deal with the Depositary for all purposes of this

Agreement (including receiving approvals, votes or consents hereunder) as the Holder of the Global Units and Global Purchase Contracts and shall have no obligation to the Beneficial Owners;

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

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

     Section 3.07. Notices to Holders. Whenever a notice or other communication to the Holders is required to be given under this Agreement, the Company or the Company’s agent shall give such notices and communications to the Holders and, with respect to any Units or Purchase Contracts registered in the name of the Depositary or the nominee of the Depositary, the Company or the Company’s agent shall, except as set forth herein, have no obligations to the Beneficial Owners.

     Section 3.08. Appointment of Successor Depositary. If the Depositary elects to discontinue its services as securities depositary with respect to the Units or Purchase Contracts, the Company may, in its sole discretion, appoint a successor Depositary with respect to such Units or such Purchase Contracts, as the case may be.

     Section 3.09. Definitive Securities.

     If:

     (i) the Depositary in no longer a Clearing Agency or elects to discontinue its services as securities depositary with respect to the Global Securities and a successor Depositary is not appointed within 90 days after such discontinuance pursuant to Section 3.08;

     (ii) an Event of Default occurs and is continuing; or

     (iii) the Company elects, in its sole discretion, to terminate the book-entry system for the Global Securities,

then (x) Definitive Securities shall be prepared by the Company with respect to such Global Securities and delivered to the Purchase Contract Agent and the Trustee, as appropriate, and (y) upon surrender of such Global Securities by the Depositary, accompanied by registration instructions, the Company shall cause Definitive Securities to be delivered to Beneficial Owners in accordance with the instructions of the Depositary. The Company shall not be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be protected in relying on, such instructions. Each Definitive Security so delivered shall evidence Units, Purchase Contracts or Notes, as the case may be, of the same kind and tenor as the Global

Security so surrendered in respect thereof. Notwithstanding the foregoing, the exchange of Global Notes for Notes in definitive form shall be governed by the Indenture.

     Section 3.10. Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Equity-Linked Security 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 Equity-Linked Security, evidencing the same number of Units or Separate Purchase Contracts, as the case may be, and bearing a security 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 Equity-Linked Security, and (ii) such security or indemnity as may be reasonable required by them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Purchase Contract Agent that such Equity-Linked Security has been acquired by a protected purchaser, the Company shall execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent shall authenticate, execute on behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed, lost or stolen Equity-Linked Security, a new Equity-Linked Security, evidencing the same number of Units or Separate Purchase Contracts, as the case may be, and bearing a security 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, an Equity-Linked Security on or after the Business Day immediately preceding the earliest of the Mandatory Settlement Date, any Early Settlement Date, any Early Mandatory Settlement Date or any Fundamental Change Early Settlement Date with respect to such Equity-Linked Securities. In lieu of delivery of a new Equity-Linked Security, 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 if the Mandatory Settlement Date, any Early Settlement Date, any Early Mandatory Settlement Date or any Fundamental Change Early Settlement Date with respect to such Equity-Linked Securities has occurred, deliver the shares of Common Stock deliverable in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with the Separate Note, if such Equity-Linked Securities is a Unit).

     Upon the issuance of any new Equity-Linked Security under this Section 3.10, 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 Equity-Linked Security issued pursuant to this Section 3.10 in lieu of any destroyed, lost or stolen Equity-Linked Security shall constitute an original additional contractual obligation of the Company and of the Holder in respect of the Unit or Separate Purchase Contract, as the case may be, evidenced thereby, whether or not the destroyed, lost or stolen

Equity-Linked Security shall be found at any time. Such new Equity-Linked Security (and the Units or Separate Purchase Contracts, as applicable, 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 Equity-Linked Securities delivered hereunder.

     The provisions of this Section 3.10 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 Equity-Linked Securities.

     Section 3.11. Persons Deemed Owners. Prior to due presentment of an Equity-Linked Security 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 Equity-Linked Security is registered as the owner of the Unit or Purchase Contract, as the case may be, evidenced thereby, for the purpose of performance of the Units or Purchase Contracts, as applicable, evidenced by such Equity-Linked Securities and for all other purposes whatsoever, 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 Unit or Global Purchase Contract, 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 the Depositary (or its nominee), as a Holder, with respect to such Global Unit or Global Purchase Contract or impair, as between such Depositary and the related Beneficial Owner, the operation of customary practices governing the exercise of rights of the Depositary (or its nominee) as Holder of such Global Unit or Global Purchase Contract.

     Section 3.12. Cancellation. All Securities surrendered for separation or recreation and all Equity-Linked Securities surrendered for settlement or upon the registration of transfer or exchange of a Purchase Contract shall, if surrendered to any Person other than the Purchase Contract Agent, be delivered to the Purchase Contract Agent and, if not already cancelled, be promptly cancelled by it. In the case of a Unit or Units surrendered for settlement, the Company and the Trustee shall promptly authenticate and deliver in accordance with the terms of the Indenture to the Holder thereof a number of Separate Notes equal to the number of, and in the same form as, the Units so surrendered. The Company may at any time deliver to the Purchase Contract Agent for cancellation any Equity-Linked Securities previously authenticated, executed and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Equity-Linked Securities so delivered shall, upon an Issuer Order, be promptly cancelled by the Purchase Contract Agent. No Equity-Linked Securities shall be authenticated, executed on behalf of the Holder and delivered in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Agreement. All cancelled Equity-Linked Securities held by the Purchase Contract Agent shall be disposed of in accordance with its customary practices.

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

ARTICLE 4
Settlement Of The Purchase Contracts

     Section 4.01. Settlement Rate. Each Purchase Contract obligates the Company to deliver, on the Mandatory Settlement Date, a number of shares of Common Stock (subject to Section 4.04 and Article 5) equal to the Settlement Rate as determined by the Company unless such Purchase Contract settles prior to the Mandatory Settlement Date.

     The “Settlement Rate” is equal to:

     (i) if the Applicable Market Value (as defined below) is equal to or greater than $3.94 (the “Threshold Appreciation Price”), 25.3968 shares of Common Stock for each Purchase Contract (the “Minimum Settlement Rate”);

     (ii) if the Applicable Market Value is less than the Threshold Appreciation Price but greater than $3.15 (the “Reference Price”), a number of shares of Common Stock for each Purchase Contract equal to the Stated Amount, divided by the Applicable Market Value; and

     (iii) if the Applicable Market Value is less than or equal to the Reference Price, 31.7460 shares of Common Stock for each Purchase Contract (the “Maximum Settlement Rate”),

provided that the Maximum Settlement Rate, the Minimum Settlement Rate (each, a “Fixed Settlement Rate”) and the Applicable Market Value shall be subject to adjustment as provided in Article 5 and rounded upward or downward to the nearest 1/10,000th of a share (or if there is not a nearest 1/10,000th of a share, to the next lower 1/10,000th of a share).

     Section 4.02. Representations and Agreements of Holders. Each Holder of a Purchase Contract by its acceptance thereof:

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

     (ii) consents to the provisions hereof;

     (iii) represents that its acquisition of the Purchase Contracts and its holding of the same satisfy the applicable fiduciary requirements of ERISA, if any, and that it is entitled to exemption relief from the prohibited transaction provisions of ERISA and the

Code in accordance with one or more prohibited transaction exemptions or that such acquisition otherwise will not result in a nonexempt prohibited transaction;

     (iv) in the case of a Holder that holds a Unit, agrees, for United States tax purposes, to treat (1) a Unit as an investment unit composed of two separate instruments, in accordance with its form and (2) the Notes as indebtedness; and

     (v) agrees to be bound by the terms and provisions thereof.

     Section 4.03. Delivery Upon Settlement of the Purchase Contracts.

     (a) Unless the Purchase Contracts have previously settled, the Company shall on the Mandatory Settlement Date issue and deliver to the Purchase Contract Agent, for the benefit of the Holders of the Outstanding Purchase Contracts, the aggregate number of shares of Common Stock to which such Holders are entitled hereunder, registered in the name of the Purchase Contract Agent (or its nominee) as custodian for the Holders (such shares of Common Stock, together with any dividends or distributions for which a record date and payment date for such dividend or distribution have occurred after the due date for the delivery of the Common Shares to the Purchase Contract Agent, the “Purchase Contract Settlement Fund”).

     (b) Upon book-entry transfer of the Units or Separate Purchase Contracts or delivery of Units or Separate Purchase Contracts in definitive form to the Purchase Contract Agent with duly completed transfer instructions, the Purchase Contract Agent shall transfer the shares of Common Stock underlying such Purchase Contracts, together with (i) cash in lieu of fractional shares as provided in Section 4.04, (ii) the Separate Note (in the case of the transfer or delivery of Units, but not in the case of settlement on the Mandatory Settlement Date if such Separate Note also matures on the Mandatory Settlement Date) and (iii) any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund, but without any interest thereon, to such Holder by book-entry transfer, or other appropriate procedures, in accordance with such instructions.

     Such shares shall be registered in the name of the Holder or the Holder’s designee as specified in the settlement instructions provided by the Holder to the Purchase Contract Agent, and the Company will pay all stock transfer and similar taxes attributable to the delivery thereof, unless any such transfer or similar tax is payable in respect of any registration of such shares in a name of a Person other than the Person in whose name the Security evidencing such Purchase Contract is registered, in which case the Company shall not be required to pay any such transfer or similar tax and no such registration shall be made unless the Person requesting such registration has paid any such transfer or similar taxes required by reason of such registration in a name of a Person other than the Person in whose name the Security evidencing such Purchase Contract is registered or has established to the satisfaction of the Company that such tax either has been paid or is not payable.

     In the event a Holder fails to effect such transfer or delivery, the shares of Common Stock underlying such Purchase Contracts, and any distributions thereon, shall be held in the

name of the Purchase Contract Agent or its nominee in trust for the benefit of such Holder, until the earlier to occur of:

     (i) the surrender of the relevant Units or Separate Purchase Contracts or receipt by the Company and the Purchase Contract Agent from such Holder of satisfactory evidence that such Units or Separate Purchase Contracts have been destroyed, lost or stolen, together with any indemnity that may be required by the Purchase Contract Agent and the Company; and

     (ii) the expiration of the time period specified in the abandoned property laws of the relevant jurisdiction.

     Section 4.04. No Fractional Shares. No fractional shares or scrip certificates representing fractional shares of Common Stock shall be issued or delivered to Holders upon settlement of the Purchase Contracts. In lieu of any fractional shares of Common Stock that would otherwise be issuable upon settlement of any Purchase Contracts, a Holder of a Security shall be entitled to receive an amount in cash equal to the fraction of a share of Common Stock, calculated on an aggregate basis in respect of the Purchase Contracts being settled, multiplied by the last reported sale price of the Common Stock on the Trading Day immediately preceding the Mandatory Settlement Date, Early Settlement Date, Fundamental Change Early Settlement Date or Early Mandatory Settlement Date, as the case may be. The Company shall provide the Purchase Contract Agent from time to time with sufficient funds to permit the Purchase Contract Agent to make all cash payments required by this Section 4.04 in a timely manner.

ARTICLE 5
Adjustments

     Section 5.01. Adjustments to the Fixed Settlement Rates. (a) Each Fixed Settlement Rate shall be adjusted, from time to time and without duplication, by the Company as described in this Section 5.01 upon the occurrence of any of the following events:

     (i) the issuance of Common Stock as a dividend or distribution to all holders of Common Stock, or a subdivision or combination of Common Stock, in which event each Fixed Settlement Rate will be adjusted based on the following formula:

     SR₁ = SR₀ x (OS₁ ÷ OS₀)

     where,

     SR₀ = the Fixed Settlement Rate in effect at the close of business on the Record Date

     SR₁ = the Fixed Settlement Rate in effect immediately after the Record Date

OS0 =

the number of shares of Common Stock outstanding at the close of business on the Record Date prior to giving effect to such event

OS1		=		the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such event

     (ii) the issuance to all holders of Common Stock of rights or warrants entitling them for a period expiring 60 days or less from the date of issuance of such rights or warrants to purchase shares of Common Stock at less than the Current Market Price of Common Stock as of the Record Date, in which event each Fixed Settlement Rate will be adjusted based on the following formula:

SR1		=		SR0 x (OS0 + X) ÷ (OS0 + Y)

where,

SR0		=		the Fixed Settlement Rate in effect at the close of business on the Record Date
SR1		=		the Fixed Settlement Rate in effect immediately after the Record Date
OS0		=		the number of shares of Common Stock outstanding at the close of business on the Record Date
X		=		the total number of shares of Common Stock issuable pursuant to such rights or warrants
Y		=		the aggregate price payable to exercise such rights, divided by the average of the Daily VWAP of Common Stock over each of the 10 consecutive Trading Days prior to the Business Day immediately preceding the announcement of the issuance of such rights or warrants

However, each Fixed Settlement Rate will be readjusted to the extent that any such rights or warrants are not exercised prior to their expiration.

     (iii) the dividend or other distribution to all holders of the Common Stock of shares of Capital Stock of the Company (other than Common Stock), evidences of the Company’s indebtedness, the Company’s assets or rights to acquire Capital Stock of the Company, indebtedness or assets of the Company (excluding any dividend, distribution or issuance as to which an adjustment was made pursuant to clauses (i) or (ii) above or (iv) below or the provisions of this clause (iii) relating to spin-offs), in which event each Fixed Settlement Rate will be adjusted based on the following formula:

SR1		=		SR0 x SP0 ÷ (SP0 - FMV)

where,

SR0		=		the Fixed Settlement Rate in effect at the close of business on the Record Date
SR1		=		the Fixed Settlement Rate in effect immediately after the Record Date
SP0		=		the Current Market Price as of the Record Date

FMV		=		the fair market value (as determined by the Board of Directors), on the Record Date, of the shares of Capital Stock of the Company, evidences of indebtedness, assets or rights so distributed, expressed as an amount per share of Common Stock

However, if the transaction that gives rise to an adjustment pursuant to this clause (iii) is one pursuant to which the payment of a dividend or other distribution on the Common Stock consists of shares of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company, (i.e., a spin-off) that are, or, when issued, will be, traded on a U.S. securities exchange, then each Fixed Settlement Rate will instead be adjusted based on the following formula:

SR1		=		SR0 x (FMV0 + MP0) ÷ MP0

where,

SR0		=		the Fixed Settlement Rate in effect at the close of business on the Record Date
SR1		=		the Fixed Settlement Rate in effect immediately after the Record Date
FMV0		=		the average of the VWAP of the Capital Stock or similar equity interests distributed to holders of Common Stock applicable to one share of Common Stock over each of the 10 consecutive Trading Days commencing on and including the third Trading Day after the date on which “ex-distribution trading” commences for such dividend or distribution on the NYSE or such other national or regional exchange or market on which such Capital Stock or similar equity interests are then listed or quoted
MP0		=		the average Daily VWAP of the Common Stock over each of the 10 consecutive Trading Days commencing on and including the third Trading Day after the date on which “ex-distribution trading” commences for such dividend or distribution on the NYSE or such other national or regional exchange or market on which Common Stock is then listed or quoted

     (iv) the Company makes a distribution consisting exclusively of cash to all holders of the Common Stock, excluding (a) any cash that is distributed as part of a distribution referred to in clause (iii) above and (b) any consideration payable in connection with a tender or exchange offer made by the Company or any of its Subsidiaries referred to in clause (v) below, in which event, each Fixed Settlement Rate will be adjusted based on the following formula:

SR1		=		SR0 x SP0 ÷ (SP0 – C)

where,

SR0		=		the Fixed Settlement rate in effect at the close of business on the Record Date
SR1		=		the Fixed Settlement Rate in effect immediately after the Record Date

SP0		=		the Current Market Price as of the Record Date
C		=		the amount in cash per share the Company distributes to holders of Common Stock

     (v) the Company or one or more of its Subsidiaries makes purchases of Common Stock pursuant to a tender offer or exchange offer by the Company or one of its Subsidiaries for Common Stock to the extent that the cash and value of any other consideration included in the payment per share of Common Stock validly tendered or exchanged exceeds the Daily VWAP per share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Date”), in which event each Fixed Settlement Rate will be adjusted based on the following formula:

SR1		=		SR0 x (FMV + (SP1 x OS1)) ÷ (SP1 x OS0)

where,

SR0		=		the Fixed Settlement Rate in effect at the close of business on the Expiration Date
SR1		=		the Fixed Settlement Rate in effect immediately after the Expiration Date
FMV		=		the fair market value (as determined by the Board of Directors), on the Expiration Date, of the aggregate value of all cash and any other consideration paid or payable for shares validly tendered or exchanged and not withdrawn as of the Expiration Date (the “Purchased Shares”)
OS1		=		the number of shares of Common Stock outstanding as of the last time tenders or exchanges may be made pursuant to such tender or exchange offer (the “Expiration Time”) less any Purchased Shares
OS0		=		the number of shares of Common Stock outstanding at the Expiration Time, including any Purchased Shares
SP1		=		the average Daily VWAP of the Common Stock over each of the 10 consecutive Trading Days commencing with the Trading Day immediately after the Expiration Date;

     (b) Except as stated in subsection (a) above or as otherwise agreed, the Fixed Settlement Rates shall not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing or for the repurchase of Common Stock. In addition, there shall be no adjustment to the Fixed Settlement Rates in case of the issuance of any shares of Common Stock in a Business Combination as provided in Section 5.02.

     (c) To the extent that the Company has a rights plan in effect upon settlement of a Purchase Contract, the Holder of such Purchase Contract will receive, in addition to Common

Stock, the rights under the rights plan, unless, prior to the settlement of such Purchase Contract, the rights have separated from the Common Stock, in which case each Fixed Settlement Rate shall be adjusted at the time of separation as if the Company made a distribution to all holders of the Common Stock as described in Section 5.01(a)(iii).

     (d) Any Fixed Settlement Rate adjustments described in subsection (a) above that are attributable to an exercise or exchange of Rights shall not apply to adjust any such Fixed Settlement Rate of any Units or Purchase Contracts that are directly or indirectly owned by an Acquiring Person. For this purpose, the terms “Rights” and “Acquiring Person” have the meanings assigned to such terms in the Tax Benefits Preservation Plan.

     (e) The Company may, but shall not be required to, make such increases in each Fixed Settlement Rate as the Company deems advisable. The Company may only make such a discretionary adjustment if the Company makes the same proportionate adjustment to each Fixed Settlement Rate. No adjustment in either Fixed Settlement Rate will be required unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided further that any such adjustment of less than one percent that has not been made shall be made (x) upon the end of the Company’s fiscal year commencing with the 2010 fiscal year and (y) upon the Mandatory Settlement Date or any earlier Fundamental Change Early Settlement Date, Early Settlement Date or Early Mandatory Settlement Date.

     (f) Adjustments to each Fixed Settlement Rate shall be calculated to the nearest 1/10,000th of a share.

     (g) Whenever the Fixed Settlement Rates are adjusted, the Company must deliver to the Purchase Contract Agent an Officers’ Certificate setting forth each Fixed Settlement Rate, detailing the calculation of each Fixed Settlement Rate and describing the facts upon which the adjustment is based. In addition, the Company must notify the holders of Units and Separate Purchase Contracts of the adjustment within 10 Business Days of any event requiring such adjustment and describe in reasonable detail the method by which each Fixed Settlement Rate was adjusted; such notification may be made by a press release (notwithstanding Section 1.06). The Purchase Contract Agent shall not at any time be under any duty or responsibility to any Holder of Purchase Contracts to determine whether any facts exist that may require any adjustment of any Fixed Settlement Rate or Reference Property, 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 other Reference Property that may at the time be 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 transfer or deliver any shares of Common Stock or other Reference Property pursuant to a Purchase Contract or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 5. All

calculations and determinations pursuant to this Article 5 shall be made by the Company or its agent and the Purchase Contract Agent shall have no responsibility with respect thereto.

     (h) If the Company takes a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and thereafter but before the distribution to stockholders thereof, the Company legally abandons its plan to pay or deliver the dividend or distribution, then no adjustment in any Fixed Settlement Rate then in effect shall be required by reason of the taking of that record.

     (i) Each adjustment to each Fixed Settlement Rate shall result in a corresponding adjustment to the Early Settlement Rate, the Early Mandatory Settlement Rate and the Stock Prices pursuant to Section 5.03(d). Each adjustment to each Fixed Settlement Rate will also result in a corresponding (but inverse) adjustment to the Applicable Market Value solely to determine which of the three clauses in the definition of Settlement Rate will be applicable on the Mandatory Settlement Date. In addition, if any adjustment to the Settlement Rate becomes effective, or any Ex-Date or Record Date for any issuance, dividend or distribution (relating to a required Fixed Settlement Rate adjustment) occurs, during the period beginning on, and including, (i) the open of business on the first Trading Day of the 20 Trading Day period during which the Applicable Market Value is calculated or (ii) in the case of an Early Settlement, an Early Settlement upon a Fundamental Change or an exercise of the Company’s Early Mandatory Settlement Right, the relevant Early Settlement Date, Fundamental Change Early Settlement Date or Early Mandatory Settlement Date and, in each case, ending on, and including, the date on which the Company delivers shares of its Common Stock under the related Purchase Contract, the Company will make appropriate adjustments to the Fixed Settlement Rates and/or the number of shares of its Common Stock deliverable upon settlement of the Purchase Contract, in each case, consistent with the provisions of this Section 5.01.

     (j) The Board of Directors shall have the power to resolve any ambiguity or, subject to applicable law, correct any error in this Article 5, and its action in so doing shall be final and conclusive.

     (k) For purposes of Section 5.01 and Section 5.02, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company.

     Section 5.02. Business Combinations. In the event of:

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

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

     (c) any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition) or any binding share exchange which reclassifies or changes the outstanding Common Stock or

     (d) any liquidation, dissolution or winding up of the Company (any such event described in clause (a) through (d) above, a “Business Combination”),

then, at and after the effective time of the Business Combination, (i) each Purchase Contract then outstanding shall become a Purchase Contract to purchase the kind and amount of securities, cash or property receivable upon any such Business Combination by the holder of one share of Common Stock, multiplied by the applicable Settlement Rate (the “Reference Property” with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) and (ii) the Applicable Market Value of the Common Stock shall be calculated based on the value of a unit of Reference Property that a holder of the Common Stock would have received in such transaction, as follows (x) with respect to any publicly traded securities that comprise all or part of the Reference Property, based on the VWAP of such securities, (y) in the case of any cash that comprises all or part of the Reference Property, based on the amount of such cash and (C) in the case of any other property that comprises all or part of the Reference Property, based on the value of such property, as determined by a nationally recognized independent investment banking firm retained by the Company for this purpose. In the event holders of the Common Stock have the opportunity to elect the form of consideration to be received in such Business Combination, the Reference Property shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of the Common Stock that affirmatively make an election. In the event of a Business Combination where the Company is not the successor Person, such Person formed by such Business Combination shall execute and deliver to the Purchase Contract Agent an agreement supplemental hereto providing that each Holder of an Outstanding Purchase Contract (whether or not included in a Unit) shall have the rights provided by this Section 5.02. Such supplemental agreement shall provide for adjustments which, for events subsequent to the effective date of such Business Combination, shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 5.01 (with respect to any Reference Property consisting of publicly traded securities) and this Section 5.02. The above provisions of this Section 5.02 shall similarly apply to successive Business Combinations. The Company shall notify Holders of the composition of the Reference Property as soon as practicable after such determination is made. The Company shall not become a party to any Business Combination unless its terms are consistent with this Section 5.02.

     Section 5.03. Early Settlement Upon A Fundamental Change. (a) If a Fundamental Change occurs and a Holder elects to settle its Purchase Contracts in connection with such Fundamental Change, such Holder shall receive a number of shares of Common Stock (or cash, securities or other property) based on the Fundamental Change Early Settlement Rate (the “Fundamental Change Early Settlement Right”). An Early Settlement shall be deemed for these purposes to be “in connection with” such Fundamental Change if the Holder delivers an Early Settlement Notice to the Purchase Contract Agent, and otherwise satisfies the requirements for effecting Early Settlement of its Purchase Contracts, during the period beginning on, and

including, the Effective Date of the Fundamental Change and ending on, and including, the 30th Business Day thereafter (“the Fundamental Change Early Settlement Date”).

     (b) The Company shall provide the Purchase Contract Agent and the Holders of Units and Separate Purchase Contracts with a notice of a Fundamental Change within five Business Days after its occurrence, issue a press release announcing the Effective Date and post such press release on its website. The notice shall set forth, among other things, (i) the applicable Fundamental Change Early Settlement Rate, (ii) the kind and amount of the cash, securities and other consideration receivable by the Holder upon settlement and (iii) the deadline by which each Holder’s Fundamental Change Early Settlement Right must be exercised.

     (c) The “Fundamental Change Early Settlement Rate” shall be determined by the Company by reference to the table below, based on the date on which the Fundamental Change occurs or becomes effective (the “Effective Date”) and the stock price (the “Stock Price”) in the Fundamental Change, which shall be:

     (i) in the case of a Fundamental Change described in clause (ii) of the definition thereof in which holders of shares of Common Stock receive only cash in the Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock; and

     (ii) in all other cases, the Stock Price shall be the average of the Daily VWAP of the Common Stock on the 10 Trading Days immediately prior to but not including the Effective Date.

     (d) The Stock Prices set forth in the first column of the table below shall be adjusted as of any date on which any Fixed Settlement Rate is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Fixed Settlement Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Fixed Settlement Rate as so adjusted. The number of shares in the table below shall be adjusted in the same manner as the Fixed Settlement Rates as set forth in Section 5.01.

     (e) The following table sets forth the Fundamental Change Early Settlement Rate per Purchase Contract for each Stock Price and Effective Date set forth below:

		Effective Date
		December 22,				December 15,				December 15,				December 15,
Stock Price		2009				2010				2011				2012
$1.00			29.2009				30.2782				31.4081				31.7460

$3.75			25.0253				25.5036				26.1926				26.6667

		Effective Date
		December 22,				December 15,				December 15,				December 15,
Stock Price		2009				2010				2011				2012
$3.94			24.9653				25.4099				26.0255				25.3968

$5.00			24.7899				25.1126				25.4886				25.3968

     The exact Stock Prices and Effective Dates may not be set forth in the table above, in which case:

	(i)		if the Stock Price is between two Stock Prices in the table or the Effective Date is between two Effective Dates in the table, the Fundamental Change Early Settlement Rate shall be determined by a straight-line interpolation between the number of shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365-day year;
	(ii)		if the Stock Price is greater than $5.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the table above), the Fundamental Change Early Settlement Rate shall be the Minimum Settlement Rate; or
	(iii)		if the Stock Price is less than $1.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the table above), the “Minimum Stock Price,” the Fundamental Change Early Settlement Rate shall be determined as if the Stock Price equaled the Minimum Stock Price, and using straight line interpolation, as described in clause (i) of this Section 5.04(e), if the Effective Date is between two dates in the table.

The maximum number of shares of Common Stock deliverable under a Purchase Contract is 31.7460, subject to adjustment in the same manner as the Fixed Settlement rates as set forth under Section 5.01.

     (f) If a Holder exercises its Fundamental Change Early Settlement Right following the Effective Date of a Fundamental Change described in clause (b) of the definition thereof, the Company shall deliver to such Holder the kind and amount of securities, cash or other property that such Holder would have been entitled to receive in such Fundamental Change as a holder of a number of shares of the Common Stock equal to the Fundamental Change Settlement Rate for each Purchase Contract being settled early. If such Fundamental Change causes the Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election) and the Holder exercises the Fundamental Change Early Settlement Right, the Company shall deliver to such Holder the types and amounts of consideration as are proportional to the types and amounts of consideration received by the holders of the Common Stock that affirmatively make such an election. The Company shall deliver the shares of Common Stock, securities, cash or other property payable as a result of such Holder’s exercise of the Fundamental Change Early Settlement Right on the third Business Day following the Fundamental Change Early Settlement Date.

     (g) If a Holder does not elect to exercise the Fundamental Change Early Settlement Right, such Holder’s Purchase Contracts shall remain outstanding and shall be subject to normal settlement on any subsequent Early Settlement Date, Early Mandatory Settlement Date, the Mandatory Settlement Date or Fundamental Change Early Settlement Date, including, if applicable, the provisions set forth in Section 5.02 regarding the occurrence of a Business Combination.

     Section 5.04. Early Settlement. (a) Subject to and upon compliance with the provisions of this Section 5.04, on any Trading Day prior to the close of business on the third Business Day immediately preceding the Mandatory Settlement Date, a Holder may elect to settle its Purchase Contracts early, in whole or in part (“Early Settlement”) at the Early Settlement Rate.

     (b) A Holder’s right to receive Common Stock upon Early Settlement of any of its Purchase Contracts is subject to the following conditions:

     (i) delivery of a written and signed notice of election (an “Early Settlement Notice”) to the Purchase Contract Agent electing Early Settlement of such Purchase Contract;

     (ii) surrendering the relevant Definitive Security, if such Purchase Contract or the Unit that includes such Purchase Contract is in the form of a Definitive Security, to the Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank with the form of Election to Settle Early on the reverse thereof duly completed, or if such Purchase Contract is represented by a Global Security, compliance with the applicable procedures of the Depositary; and

     (iii) payment by such Holder of any transfer or similar taxes payable in connection with the issuance of Common Stock to any Person other than such Holder pursuant to subsection (c) below.

If a Holder complies with the requirements set forth in clauses (i) through (iii) above earlier than the close of business on any Business Day, then that Business Day shall be considered the “Early Settlement Date.” If a Holder complies with the requirements set forth in clauses (i) through (iii) above on any Business Day or at any time on a day that is not a Business Day, then the next Business Day shall be considered the “Early Settlement Date.”

     (c) Upon surrender or book-entry transfer of such Purchase Contracts or the related Units, the Company shall cause a number of shares of Common Stock, calculated at the Early Settlement Rate to be issued and delivered, together with payment in lieu of any fraction of a share as provided in Section 4.04, as promptly as practicable, but no later than the third Business Day following the Early Settlement Date. Such shares shall be registered in the name of the Holder or the Holder’s designee, and shall be delivered, as specified on the applicable form of Election to Settle Early provided by the Holder to the Purchase Contract Agent. If any shares of Common Stock deliverable in respect of a Purchase Contract are to be registered to a Person other than the Person in whose name the Security 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.

     (d) In the event that Early Settlement is effected with respect to Purchase Contracts that are a component of Units, upon such Early Settlement the Company shall execute and the Trustee shall execute on behalf of the Holder, authenticate and deliver to the Holder thereof, at the expense of the Company, a Security, in the same form as the Units submitted to effect such Early Settlement, evidencing a number of Separate Notes equal to the number of Purchase Contracts as to which Early Settlement was effected.

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

     Section 5.05. Early Mandatory Settlement at the Company’s Election. (a) The Company has the right to settle the Purchase Contracts early, in whole but not in part (the “Early Mandatory Settlement Right”), on a date fixed by it (the “Early Mandatory Settlement Date”) at the Early Mandatory Settlement Rate.

     (b) If the Company elects to exercise its Early Mandatory Settlement Right, the Company will provide the Purchase Contract Agent and the Holders of Units, Separate Purchase Contracts and Separate Notes with a notice of its election (the “Early Mandatory Settlement Notice”), issue a press release announcing its election and post such press release on its website. The Early Mandatory Settlement Notice shall specify, among other things:

     (i) the Early Mandatory Settlement Rate;

     (ii) the Early Mandatory Settlement Date, which will be at least 5 but not more than 30 Business Days following the date of the Company’s notice (the “Notice Date”);

     (iii) whether Holders of Units and Separate Notes will have the right to require the Company to repurchase their Notes that are a component of the Units or their Separate Notes, as the case may be;

     (iv) if applicable, the Repurchase Price and Repurchase Date (each as defined in the Indenture);

     (v) if applicable, the last date on which Holders may exercise their Repurchase Right (as defined in the Indenture); and

     (vi) if applicable, the procedures that Holders must following to require the Company to repurchase their Notes (in accordance with the Indenture).

     The Company will deliver the shares of Common Stock and any cash payable for fractional shares to the Holders of the Purchase Contract on the Early Mandatory Settlement Date.

ARTICLE 6
Remedies

     Section 6.01. Unconditional Right of Holders to Receive Shares of Common Stock. Each Holder of a Purchase Contract (whether or not included in a Unit) shall have the right, which is absolute and unconditional, to receive the shares of Common Stock pursuant to such Purchase Contract and to institute suit for the enforcement of any such right to receive the shares of Common Stock, and such right shall not be impaired without the consent of such Holder.

     Section 6.02. Limitation on Proceedings. No Holder of Purchase Contracts may institute any proceedings, judicial or otherwise, with respect to this Agreement or for any remedy hereunder, except in the case of failure of the Purchase Contract Agent, for 60 days, to act after the Purchase Contract Agent has received a written request to institute proceedings in respect of a default with respect to any covenant hereunder from the Holders of not less than 25% of the Outstanding Purchase Contracts, as well as an offer of indemnity reasonably satisfactory to the Purchase Contract Agent. This provision will not prevent any Holder of Purchase Contracts from instituting suit for the delivery of Common Stock deliverable upon settlement of the Purchase Contracts on the Mandatory Settlement Date or any Early Settlement Date, Fundamental Change Settlement Date or Early Mandatory Settlement Date.

     Section 6.03. Restoration of Rights and Remedies. If any Holder has instituted any proceeding to enforce any right or remedy under this Agreement and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to such Holder, then and in every such case, subject to any determination in such proceeding, the Company and such Holder shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of such Holder shall continue as though no such proceeding had been instituted.

     Section 6.04. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 3.10, no right or remedy herein conferred upon or reserved to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

     Section 6.05. Delay or Omission Not Waiver. No delay or omission of any Holder to exercise any right or remedy upon a default hereunder shall impair any such right or remedy or constitute a waiver of any such right. Every right and remedy given by this Article or by law to the Holders may be exercised from time to time, and as often as may be deemed expedient, by such Holders.

     Section 6.06. Undertaking for Costs. All parties to this Agreement agree, and each Holder of a Purchase Contract, by its acceptance of such Purchase Contract shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Agreement, or in any suit against the Purchase Contract Agent for any action taken, suffered or omitted by it as Purchase Contract Agent, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and costs against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; provided that the provisions of this Section shall not apply to any suit instituted by (a) the Purchase Contract Agent, (b) any Holder, or group of Holders, holding in the aggregate more than 10% of the Outstanding Purchase Contracts, or (c) any Holder for the enforcement of the right to receive shares of Common Stock or other Reference Property under the Purchase Contracts held by such Holder.

     Section 6.07. Waiver of Stay or Execution Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or assume or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Agreement; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Purchase Contract Agent or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted.

     Section 6.08. Control by Majority. The Holders of not less than a majority of the Outstanding Purchase Contracts shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Purchase Contract Agent, or of exercising any trust or power conferred upon the Purchase Contract Agent; provided that the Purchase Contract Agent has received indemnity satisfactory to it. Notwithstanding the foregoing, the Purchase Contract Agent may refuse to follow any direction that is in conflict with any law or the Purchase Contract Agreement, that may involve it in personal liability or that may be unduly prejudicial to the Holders of Purchase Contracts not joining in the action.

In case of any such merger, consolidation, sale, assignment, transfer or conveyance (but not any such lease) and upon any such assumption by a successor entity in accordance with Section 9.01, such successor entity shall succeed to and be substituted for the Company with the same effect as if it had been named herein as the Company. Such successor entity thereupon may cause to be signed, and may issue either in its own name or in the name of Citigroup Inc., any or all of the Securities evidencing Units or Purchase Contracts issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Purchase Contract Agent; and, upon the order of such successor entity, instead of the Company, and subject to all the terms, conditions and limitations in this Agreement prescribed, the Purchase Contract Agent shall authenticate and execute on behalf of the Holders and deliver any such Securities that previously shall have been signed and delivered by the officers of the Company to the Purchase Contract Agent for authentication and execution, and any such Security evidencing Units or Purchase Contracts that such successor corporation thereafter shall cause to be signed and delivered to the Purchase Contract Agent for that purpose. All the Securities issued shall in all respects have the same legal rank and benefit under this Agreement as the Securities theretofore or thereafter issued in accordance with the terms of this Agreement as though all of such Securities had been issued at the date of the execution hereof.

     In the event of any such merger, consolidation, sale, assignment, transfer, lease or conveyance, such change in phraseology and form (but not in substance) may be made in the Securities evidencing Units or Purchase Contracts thereafter to be issued as may be appropriate.

     Section 9.03. Officers’ Certificate and Opinion of Counsel Given to Purchase Contract Agent. The Purchase Contract Agent, subject to Section 7.01 and Section 7.03, shall receive an Officers’ Certificate and an Opinion of Counsel as conclusive evidence that any such merger, consolidation, conversion, sale, assignment, transfer, lease or conveyance, and any such

assumption, complies with the provisions of this Article and that all conditions precedent to the consummation of any such merger, consolidation, sale, assignment, transfer, lease or conveyance have been met.

ARTICLE 10
Covenants of the Company

     Section 10.01. Performance Under Purchase Contracts. The Company covenants and agrees for the benefit of the Holders from time to time of the Purchase Contracts that it will duly and punctually perform its obligations under the Purchase Contracts in accordance with the terms of the Purchase Contracts and this Agreement.

     Section 10.02. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, New York City an office or agency where Securities may be presented or surrendered for acquisition of shares of Common Stock upon settlement of the Purchase Contracts on the Mandatory Settlement Date, any Early Settlement Date or any Early Mandatory Settlement Date and where notices and demands to or upon the Company in respect of the Purchase Contracts and this Agreement may be served. The Company will give prompt written notice to the Purchase Contract Agent of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Purchase Contract Agent with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Company hereby appoints the Purchase Contract Agent as its agent to receive all such presentations, surrenders, notices and demands.

     The Company may also from time to time designate one or more other offices or agencies where Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the Borough of Manhattan, New York City for such purposes. The Company will give prompt written notice to the Purchase Contract Agent of any such designation or rescission and of any change in the location of any such other office or agency. The Company hereby designates as the place of payment for the Purchase Contracts the Corporate Trust Office and appoints the Purchase Contract Agent at its Corporate Trust Office as paying agent in such city.

     Section 10.03. Statements of Officers of the Company as to Default. The Company will deliver to the Purchase Contract Agent, within 120 days after the end of each fiscal year of the Company (which as of the date hereof is December 31) ending after the date hereof, an Officers’ Certificate (one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company), stating whether or not to the knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions hereof, and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge.

     Section 10.04. Existence. Except as otherwise permitted under Article 9, the Company will do or cause to be done all things necessary to maintain in full force its legal existence, rights (charter and statutory) and franchises, except that the Company is not required to preserve any right or franchise if the Company determines that it is no longer desirable in the conduct of its business and the loss is not disadvantageous in any material respect to the Holders of any Purchase Contracts.

     Section 10.05. Company to Reserve Common Stock. The Company shall at all times prior to the Mandatory Settlement Date reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for issuance upon settlement of the Purchase Contracts, that number of shares of Common Stock as shall from time to time be issuable upon the settlement of all Outstanding Purchase Contracts (whether or not included in a Unit), assuming settlement at the Maximum Settlement Rate.

     Section 10.06. Covenants as to Common Stock. The Company covenants that all shares of Common Stock that may be issued upon settlement of any Purchase Contract represented by the Outstanding Securities will, upon issuance, be duly authorized, validly issued, fully paid and nonassessable, free from all taxes, liens and charges and not subject to any preemptive rights.

     The Company further covenants that, if at any time the Common Stock shall be listed on the NYSE or any other national securities exchange, the Company will, if permitted by the rules of such exchange, list and keep listed, so long as the Common Stock shall be so listed on such exchange, all Common Stock issuable upon settlement of the Purchase Contracts; provided, however, that, if the rules of such exchange system permit the Company to defer the listing of such Common Stock until the first delivery of Common Stock upon settlement of Purchase Contracts in accordance with the provisions of this Agreement, the Company covenants to list such Common Stock issuable upon settlement of the Purchase Contracts in accordance with the requirements of such exchange at such time.

     Section 10.07. Tax Treatment. The Company agrees, and by purchasing a Unit each Holder agrees, for United States tax purposes, to treat (1) a Unit as an investment unit composed of two separate instruments, in accordance with its form and (2) the Notes as indebtedness.

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

CITIGROUP INC., a Delaware corporation (the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the initial principal sum of $20.284 for each of the number of Notes set forth above, or such lesser number of Notes as set forth in the Schedule of Increases or Decreases in the Note attached hereto, in quarterly installments (each constituting a payment of interest at the rate per year of 6.15% and a partial repayment of principal) payable on March 15, June 15, September 15 and December 15 of each year (each such date, an “Installment Payment Date” and the period from, and including, December 22, 2009 to, but excluding, the first Installment Payment Date and each subsequent full quarterly period from and including an Installment Payment Date to, but excluding, the immediately succeeding Installment Payment Date, an “Installment Payment Period”), commencing on March 15, 2010, all as set forth on the reverse hereof, with the final installment due and payable on December 15, 2012. The installment amount payable on any Installment Payment Date shall be computed on the basis of a 360-day year consisting of twelve 30-day months. If an installment is payable for any period shorter than a full Installment Payment Period, such installment shall be computed on the basis of the actual number of days elapsed per 30-day month. In the event that any date on which an installment is payable is not a Business Day, then payment of the installment on such date will be made on the next succeeding day that is a Business Day, and without any interest or other payment in respect of any such delay. However, if such Business Day is in the next succeeding calendar year, then such installment payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. Installments shall be paid to the person in whose name the Note is registered, with limited exceptions, at the close of business on the Business Day immediately preceding the related Installment Payment Date (each, a “Regular Record Date”). If the Notes do not remain in book-entry only form, the Company shall have the right to select Regular Record Dates, which will be more than 14 days but less than 60 days prior to the relevant Installment Payment Date. Any such installment payment not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the registered Holders at the close of business on such Regular Record Date and may be paid to the Person in whose name this Note (or one or more successor Securities) is registered at the close of business on a special record date to be fixed by

the Trustee for the payment of such defaulted installment, notice whereof shall be given to the registered Holders of the Notes not less than 10 days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Installments shall be payable at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York; provided, however, that payment of installments may be made at the option of the Company by check mailed to the registered Holder at such address as shall appear in the Security Register or by wire transfer to an account appropriately designated by the Holder entitled to payment.

     This Note shall not be entitled to any benefit under the Indenture hereinafter referred to or be valid or obligatory for any purpose until the Certificate of Authentication shall have been signed by or on behalf of the Trustee.

     The provisions of this Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

     IN WITNESS WHEREOF, the Company has caused this instrument to be executed.

     This Security is not entitled to the benefit of any sinking fund. The Indenture contains provisions for defeasance and covenant defeasance at any time of the indebtedness on this

Security upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security.

     If an Event of Default with respect to the Notes shall occur and be continuing, then either the Trustee or the Holders of not less than 25% in principal amount of the Notes of this series then outstanding may declare the aggregate principal amount of the Notes of this series, and all interest accrued thereon, to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the holders of not less than a majority in principal amount of the Securities at the time outstanding of each series issued under the Indenture to be affected thereby, to execute supplemental indentures for certain purposes as described therein.

     Obligations Unconditional.
