Section 1.03. Form of Documents Delivered.

Section 1.04. Acts of Holders; Record Dates.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Purchase Contract Agreement to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Purchase Contract Agent and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Purchase Contract Agreement and (subject to Section 7.01) conclusive in favor of the Purchase Contract Agent and the Company, if made in the manner provided in this Section.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved in any manner which the Purchase Contract Agent deems sufficient.

(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 Purchase Contract 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, however, 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 1.05.

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, however, 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 1.05, 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 anything to the contrary in the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date.

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 Purchase Contract 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.

(c) Notwithstanding the foregoing or any other provision of this Purchase Contract Agreement to the contrary, whenever notice is required to be given to a holder of a Global Security pursuant to this Purchase Contract Agreement, such notice shall be sufficiently given if given to the Depositary for such Security (or its designee), pursuant to the Applicable Procedures.

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.

(a) On any Business Day during the period beginning on, and including, the Business Day immediately succeeding the Issue Date to, but excluding, the third Business Day immediately preceding the Scheduled Mandatory Settlement Date or an Early Mandatory Settlement Date or any Acquisition Redemption 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 (26817R 124 and 00000X000), 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, following which the Purchase Contract Agent or Trustee, as applicable, shall register (i) a decrease in the Global Unit and the amount of Purchase Contracts and Notes represented by the Component Purchase Contract and the Component Note attached to the Global Unit as Attachments 3 and 4, respectively, as set forth in Schedule A to each such attachment, and (ii) a corresponding increase in the amounts of the Global Purchase Contract and Global Note. If, however, such Unit is in the form of a Definitive Security in accordance with Section 3.09, 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 Separate 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, the Trustee and the Purchase Contract Agent shall not be responsible for any such fees or expenses.

Each of the Purchase Contract Agent and the Trustee is authorized to act in accordance with any letter of representations executed by the Company in favor of DTC.

Section 2.04. Recreation of Units.

(a) On any Business Day before the third Business Day immediately preceding the Scheduled Mandatory Settlement Date or any Early Mandatory Settlement Date or Acquisition Redemption 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 00000X000 for the Units), and each such Separate Purchase Contract and Separate Note will cease to exist immediately after such recreation. 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 to notify DTC through DTC’s DWAC System of such Beneficial Owner’s election to recreate a Unit, following which the Purchase Contract Agent or Trustee, as applicable, shall register (i) an increase in the Global Unit and the amount of Purchase Contracts and Notes represented by the Component Purchase Contract and the Component Note attached to the Global Unit as Attachments 3 and 4, respectively, as set forth in Schedule A to each such attachment, and (ii) a corresponding decrease in the amounts of the Global Purchase Contract and Global Note. If, however, such Separate Purchase Contract and Separate Note are in the form of Definitive Securities, 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, the Trustee and the Purchase Contract Agent shall not be responsible for any such fees or expenses.

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

No Equity-Linked Security shall be entitled to any benefit under this Purchase Contract 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 and Trustee (if applicable) 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.

If temporary Equity-Linked Securities are issued, the Company shall 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 Equity-Linked Securities, the Company shall execute and deliver to the Purchase Contract Agent and, in the case of Units, Trustee, and the Purchase Contract Agent and Trustee (if applicable) shall authenticate 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 Company may designate an alternative Person to act as Security Registrar by providing written notice to the Holders. 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 Trustee, and the Purchase Contract Agent and Trustee shall authenticate 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 Trustee, and the Purchase Contract Agent and, in the case of Units, the Trustee shall authenticate 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 Purchase Contract 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 transfer tax or other similar 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 3.09 and Section 8.05 not involving any transfer.

Notwithstanding anything to the contrary in the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent, and the Purchase Contract Agent and, in the case of Units, the Trustee,

shall not be obligated to authenticate 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 Close of Business on the Business Day immediately preceding the 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 or the Company, as applicable, shall, if a Settlement Date with respect to such Equity-Linked Security has occurred, deliver or cause to be delivered the shares of Common Stock deliverable (and/or, in the case of an Acquisition Redemption Settlement Date, make the required cash payment, if any) in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with Separate Notes equal to the number of, and in the same form as, the Notes evidenced by such Equity-Linked Security if such Equity-Linked Security is a Unit and if the Repurchase Right is not applicable or, if applicable, not exercised).

Section 3.06. Book-Entry Interests.

The Units, the Separate Purchase Contracts and the Separate Notes, on original issuance, will be issued in the form of one or more fully registered Global Units, Global Purchase Contracts and Global Notes, respectively, 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 Securities 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 Security representing such Beneficial Owner’s interest in such Global Security, 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 3.06 shall be in full force and effect;

(ii) the Company shall be entitled to deal with the Depositary for all purposes of this Purchase Contract Agreement (including settling Purchase Contracts, 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 as such;

(iii) to the extent that the provisions of this Section 3.06 conflict with any other provisions of this Purchase Contract 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 Purchase Contract Agreement, the Company or the Company’s agent shall give such notices and communications to the Holders and, with respect to any Units or Separate 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 Separate Purchase Contracts, the Company may, in its sole discretion, appoint a successor Depositary with respect to such Units or such Separate Purchase Contracts, as the case may be.

Section 3.09. Definitive Securities.

If:

(i) the Depositary is no longer a Clearing Agency or is unwilling or unable to continue 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; or

(ii) the Company elects, in its sole discretion, to allow some or all Global Units, Global Purchase Contracts or Global Notes to be exchangeable for securities in registered definitive form,

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, and (y) upon surrender of such Global Securities by the Depositary, accompanied by registration instructions, the Company shall cause Definitive Securities to be executed, authenticated and 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 or Separate Purchase Contracts or Separate Notes, as the case may be, of the same kind and tenor as the Global Security so surrendered in respect thereof. Notwithstanding anything to the contrary in the foregoing, the exchange of Global Notes for Separate 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, if applicable, the Trustee, and the Purchase Contract Agent and, if applicable, the Trustee shall authenticate 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, the Purchase Contract Agent and Trustee (in the case of any Units) (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 reasonably satisfactory to them to hold each of them and any agent of any of them harmless, then, in the absence of notice to the Company, the Purchase Contract Agent or Trustee that such Equity-Linked Security has been acquired by a “protected purchaser” (as such term is defined in Section 8-303 of the Uniform Commercial Code of New York as then in effect), the Company shall execute and deliver to the Purchase Contract Agent and, in the case of Units, the Trustee, and the Purchase Contract Agent and Trustee (if applicable) shall authenticate 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 anything to the contrary in the foregoing, the Company shall not be obligated to execute and deliver to the Purchase Contract Agent and Trustee, and the Purchase Contract Agent and, in the case of Units, Trustee shall not be obligated to authenticate on behalf of the Holder, and deliver to the Holder, an Equity-Linked Security on or after the Business Day immediately preceding the 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 a Settlement Date with respect to such Equity-Linked Security has occurred, deliver or arrange for delivery of the shares of Common Stock deliverable (and/or, in the case of an Acquisition Redemption Settlement Date, make the required cash payment, if any) in respect of the Purchase Contracts evidenced by such Equity-Linked Security (together with Separate Notes equal to the number of, and in the same form as, the Notes evidenced by such Equity-Linked Security if such Equity-Linked Security is a Unit and if the Repurchase Right is not applicable or, if applicable, not exercised).

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 reasonable 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 Purchase Contract 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, the Purchase Contract Agent, the Trustee and any agent of the Company, the Purchase Contract Agent or the Trustee, may treat the Person in whose name such Equity-Linked Security is registered as the absolute 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, the Purchase Contract Agent nor the Trustee, nor any agent of the Company, the Purchase Contract Agent or the Trustee, shall be affected by notice to the contrary.

None of the Purchase Contract Agent, the Trustee, the Paying Agent and the Security Registrar shall have any responsibility or obligation to any Beneficial Owner in a Global Security, an agent member or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any agent member, with respect to any ownership interest in the Equity-Linked Securities or with respect to the delivery to any agent member, Beneficial Owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Equity Linked Securities. All notices and communications to be given to the Holder and all payments to be made to Holders under the Equity Linked Securities and this Purchase Contract Agreement shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Security). The rights of Beneficial Owners in Global Securities shall be exercised only through the Depositary subject to the Applicable Procedures. The Purchase Contract Agent, the Trustee, the Paying Agent and the Security Registrar shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any Beneficial Owners. The Purchase Contract Agent, the Trustee, the Paying Agent and the Security Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered Holder of any Global Security for all purposes of this Purchase Contract Agreement relating to such Global Security (including the payment or delivery of amounts due hereunder and the giving of instructions or directions by or to any Beneficial Owner) as the sole Holder of such Global Security and shall have no obligations to the Beneficial Owners thereof. None of the Purchase Contract Agent, the Trustee, the Paying Agent and the Security Registrar shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of any such Depositary, including records in respect of the Beneficial Owners of any such Global Security, for any transactions between the Depositary and any agent member or between or among the Depositary, any such agent member and/or any Holder or Beneficial Owner of such Global Security, or for any transfers of beneficial interests in any such Global Security.

Notwithstanding anything to the contrary in the foregoing, with respect to any Global Security, nothing contained herein shall prevent the Company, the Purchase Contract Agent, the Trustee or any agent of the Company, the Purchase Contract Agent or the Trustee 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 Security or shall 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 Security.

None of the Purchase Contract Agent, the Trustee, the Paying Agent or the Security Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Purchase Contract Agreement or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among participants of DTC or members or Beneficial Owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are

expressly required by, and to do so if and when expressly required by, the terms of this Purchase Contract Agreement, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 3.12. Cancellation.

All Securities surrendered for separation or recreation and all Equity-Linked Securities surrendered for settlement or redemption or upon the registration of transfer or exchange of an Equity-Linked Security 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; provided, however, that the Purchase Contract Agent shall deliver any Notes or Separate Notes so surrendered to it to the Trustee and Paying Agent (as defined in the Indenture) for disposition in accordance with the provisions of the Indenture. The Company may at any time deliver to the Purchase Contract Agent for cancellation any Equity-Linked Securities previously executed, authenticated 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; provided, however, that if the Equity-Linked Securities so delivered are Units, the Purchase Contract Agent shall deliver the Notes comprising such Units to the Trustee and Paying Agent (as defined in the Indenture) for disposition in accordance with the provisions of the Indenture. No Equity-Linked Securities shall be executed, authenticated on behalf of the Holder and delivered in lieu of or in exchange for any Equity-Linked Securities cancelled as provided in this Section 3.12, except as expressly permitted by this Purchase Contract 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, in which case such Equity-Linked Security shall be accompanied by an Issuer Order and cancelled in accordance with the immediately preceding paragraph.

ARTICLE IV SETTLEMENT OF THE PURCHASE CONTRACTS

Section 4.01. Settlement Amount.

Each Purchase Contract obligates the Company to deliver, on the third Business Day immediately following the last VWAP Trading Day of the Observation Period, a number of shares of Common Stock (subject to Section 4.05 and Article V) equal to the Settlement Amount for such Purchase Contract, as determined by the Company (a “Mandatory Settlement”), unless such Purchase Contract previously settles early at the option of Holders pursuant to Section 4.04 or Section 5.02 or at the option of the Company pursuant to Section 4.07 or is redeemed by the Company pursuant to Section 4.08.

The “Settlement Amount” per Purchase Contract is equal to the sum of the Daily Settlement Amounts for each of the 20 consecutive VWAP Trading Days during the relevant Observation Period.

The “Daily Settlement Amount” means for each Purchase Contract and for each of the 20 consecutive VWAP Trading Days during the relevant Observation Period:

(i) if the Daily VWAP of the Common Stock is equal to or greater than $19.92 per Share, subject to adjustment as provided herein (the “Threshold Appreciation Price”), a number of shares of Common Stock equal to (i) 5.0201 shares of Common Stock, subject to adjustment as provided herein (the “Minimum Settlement Rate”) divided by (ii) 20;

(ii) if the Daily VWAP of the Common stock is less than the Threshold Appreciation Price but greater than $16.13 per Share, subject to adjustment as provided herein (the “Reference Price”), a number of shares of Common Stock equal to (i) the Unit Stated Amount divided by the Daily VWAP divided by (ii) 20; and

(iii) if the Daily VWAP of the Common Stock is less than or equal to the Reference Price, a number of shares of Common Stock equal to (i) 6.1996 shares of Common Stock, subject to adjustment as provided herein (the “Maximum Settlement Rate”) divided by (ii) 20.

The Company shall give notice of the Settlement Amount to the Purchase Contract Agent and Holders no later than the Close of Business on the Business Day immediately following the last VWAP Trading Day of the Observation Period.

Section 4.02. Representations and Agreements of Holders and Beneficial Owners.

Each Holder of a Unit or Separate Purchase Contract by its acceptance thereof, and each beneficial owner (for U.S. federal income tax purposes) of a Unit or Separate Purchase Contract by its acquisition, will be deemed to have:

(i) irrevocably authorized and directed the Purchase Contract Agent to execute and deliver on its behalf and perform the Purchase Contract Agreement on its behalf, and appointed the Purchase Contract Agent as its attorney-in-fact for any and all such purposes;

(ii) in the case of a Purchase Contract that is a component of a Unit, or that is evidenced by a Separate Purchase Contract, irrevocably authorized and directed the Purchase Contract Agent to execute, deliver and hold on its behalf the Separate Purchase Contract or the Component Purchase Contract evidencing such Purchase Contract, and appointed the Purchase Contract Agent as its attorney-in-fact for any and all such purposes;

(iii) consented to, and agreed to be bound by, the terms and provisions of this Purchase Contract Agreement;

(iv) represented that either (1) no portion of the assets used by such purchaser or subsequent transferee to acquire and hold the Units or any interest therein constitutes assets of any (A) “employee benefit plan” (as defined under Section 3(3) of Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) that is subject to Title I of ERISA, (B) plan, individual retirement account or other arrangement that is subject to Section 4975 of the Code or provisions under any federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, “Similar Laws”) or (C) entity whose underlying assets are considered to include “plan assets” of such plan, account or arrangement by reason of such plan’s, account’s or arrangement’s investment in such entity or (2) the purchase and holding of the Units (or either of the Purchase Contracts or Notes that are components thereof) and its acquiring of shares of Common Stock upon settlement of the Purchase Contracts, as the case may be, will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a similar violation of any applicable Similar Laws; and

(v) in the case of a Unit, agreed, for all purposes, including U.S. federal income tax purposes, to treat (1) a Unit as an investment unit composed of two separate instruments, in accordance with the form of Unit attached hereto as Exhibit A, (2) the Notes as indebtedness of the Company and (3) the allocation of the Unit Stated Amount between the Purchase Contract and the Note component of such Unit so that the initial tax basis in such Purchase Contract will be $81.05089 and the initial tax basis in such Note will be $18.94911.

Section 4.03. Delivery Upon Settlement of the Purchase Contracts.

(a) On each applicable Settlement Date (or, with respect to an Early Settlement Exercise Date, an Acquisition Redemption Settlement Date or a Fundamental Change Early Settlement Date, on the date provided for in the first sentence of Section 4.04(c), in Section 4.08(c) or in Section 5.02(f), respectively), the Company shall issue and deliver to the Holders of the Outstanding Purchase Contracts (or their designees), the aggregate number of shares of Common Stock (and cash in lieu of fractional shares of Common Stock to which such Holders are

entitled hereunder), registered, in the case of any shares of Common Stock, in the name of such Holders or their designees (such cash and shares of Common Stock, together with any dividends or distributions with respect to such shares for which a Record Date and payment date for such dividend or distribution have occurred on or after the applicable Determination Date, the “Purchase Contract Settlement Fund”). When any cash is required to be delivered to Holders pursuant to this Article IV or Section 5.02, the Purchase Contract Agent shall deliver such cash, including any dividends or distributions with respect to the shares constituting part of the Purchase Contract Settlement Fund (but without interest thereon) to such Holders, in accordance with the written direction of the Company.

(b) On the applicable Settlement Date, upon (i) surrender of the Units or Separate Purchase Contracts by book entry transfer or by delivery of any Units or Separate Purchase Contracts in definitive form to the Purchase Contract Agent duly endorsed for transfer to the Company or in blank and with duly completed settlement instructions in the form attached thereto, or if such Purchase Contract is represented by a Global Security, surrendering the relevant Security (or causing a reduction in the number of Purchase Contracts represented thereby, if applicable) in compliance with the standing arrangements between the Depositary and the Purchase Contract Agent, and (ii) the payment of any transfer or similar taxes payable pursuant to Section 4.03(c), the Company shall transfer the shares of Common Stock deliverable upon settlement of such Purchase Contracts, together with (i) cash in lieu of fractional shares as provided in Section 4.05, (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 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.

(c) The shares of Common Stock deliverable upon settlement of the Purchase Contracts 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 shall 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 taxes 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 surrender or delivery of its Units or Separate Purchase Contracts in accordance with the provisions hereof, the shares of Common Stock deliverable upon settlement of 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 for settlement in accordance with the provisions hereof 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 passage of two years from the applicable Settlement Date, following which the Purchase Contract Agent shall pay to the Company such Holder’s shares of Common Stock and any distributions thereon; provided, however, that the Purchase Contract Agent, before making any such payment to the Company, may at the expense of the Company cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The Borough of Manhattan, The City of New York, New York, notice that such property remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such property then remaining will be repaid to the Company. After payment to the Company, (A) Holders entitled to such property must look to the Company for payment as general creditors, unless applicable abandoned property law designates another person, and (B) all liability of the Purchase Contract Agent with respect to such property shall cease.

Section 4.04. Early Settlement.

(a) Subject to and upon compliance with the provisions of this Section 4.04, on any Business Day during the period beginning on, and including, the Business Day immediately following the Issue Date to, but excluding, the third Business Day immediately preceding the Scheduled Mandatory Settlement Date, a Holder of a Unit or Separate Purchase Contract may elect to settle its Purchase Contracts early, in whole or in part (an “Early Settlement”) at the Early Settlement Rate per Purchase Contract.

(b) A Holder’s right to receive shares of Common Stock, together with cash in lieu of fractional shares as provided in Section 4.05, 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”) in the form attached to the Purchase Contract to the Purchase Contract Agent and Company electing Early Settlement of such Purchase Contract (or, in the case of a Global Purchase Contract or a Component Purchase Contract, delivery of notice of such election in accordance with the Applicable Procedures);

(ii) if such Purchase Contract or the Unit that includes such Purchase Contract is in the form of a Definitive Security, surrendering the relevant Definitive Security to the Purchase Contract Agent at the Corporate Trust Office duly endorsed for transfer to the Company or in blank and with duly completed settlement instructions in the form attached thereto, or if such Purchase Contract is represented by a Global Security, surrendering the relevant Security (or causing a reduction in the number of Purchase Contracts represented thereby, if applicable) in compliance with the standing arrangements between the Depositary and the Purchase Contract Agent; 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 Section 4.04(c) below.

The first Business Day on which a Holder complies with the requirements set forth in clauses (i) through (iii) above before the Close of Business on such Business Day shall be considered the “Early Settlement Exercise Date.”

(c) Upon surrender or book-entry transfer of Purchase Contracts or the related Units in accordance with Section 4.03, the Company shall cause a number of shares of Common Stock, per Purchase Contract or Unit, as applicable, equal to the Early Settlement Rate to be issued and delivered, together with payment in lieu of any fraction of a share as provided in Section 4.05, on or prior to the third Business Day following the Early Settlement Exercise 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 Election to Settle Early form substantially in the form attached to Exhibit A or Exhibit B, as applicable, provided by the Holder to the Company and 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 authenticate (pursuant to the Indenture) on behalf of the Holder thereof and deliver to the Holder thereof, at the expense of the Company, a number of Separate Notes, in same form as the Notes comprising part of the Units, 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 and Trustee shall authenticate on behalf of the Holder and deliver to the

Holder thereof, at the expense of the Company, one or more Securities evidencing the Purchase Contracts (and, if applicable, Notes) as to which Early Settlement was not effected.

Section 4.05. No Fractional Shares.

The Company shall deliver cash in lieu of any fractional share of Common Stock issuable upon settlement of the Units or Separate Purchase Contracts based on the (i) Closing Price on the relevant Acquisition Redemption Settlement Date, Early Settlement Exercise Date or Early Mandatory Relevant Date, as applicable, or, if such date is not a Trading Day, the immediately preceding Trading Day (in the case of an Early Settlement or an Early Mandatory Settlement, as applicable) or (ii) Daily VWAP on the last VWAP Trading Day of the Observation Period (in the case of a Mandatory Settlement). The Company will calculate the whole number of shares of Common Stock and the amount of any fractional share of Common Stock due upon settlement of a Unit or a Separate Purchase Contract based on the aggregate number of Units or Separate Purchase Contracts being settled by each Holder with the same Early Settlement Exercise Date, Early Mandatory Relevant Date or Observation Period, as applicable, or based on such other aggregate number of Units or Separate Purchase Contracts being settled in respect of the same Early Settlement Exercise Date, Early Mandatory Relevant Date or Observation Period, as applicable, as DTC may otherwise request.

Section 4.06. Acceleration of the Mandatory Settlement Date.

If a Bankruptcy Event occurs on any day (such day the “Acceleration Date”), the Mandatory Settlement Date for each Unit or Separate Purchase Contract shall automatically be accelerated to the Acceleration Date and Holders of Purchase Contracts shall be entitled to receive, upon settlement of the Purchase Contracts on such Acceleration Date, a number of shares of Common Stock equal to the Maximum Settlement Rate in effect immediately prior to such acceleration (regardless of the market value of Common Stock). The Company shall cause to be delivered the shares of Common Stock or Units of Reference Property, as the case may be, as a result of any such acceleration of the Mandatory Settlement Date in accordance with the provisions set forth in Section 4.03, except that (i) such delivery shall be made on the accelerated Mandatory Settlement Date, and (ii) the Person in whose name any shares of Common Stock shall be issuable following such acceleration shall become the holder of record of such shares as of the Close of Business on the Acceleration Date.

Section 4.07. Early Mandatory Settlement at the Company’s election.

(a) The Company has the right (the “Early Mandatory Settlement Right”) to settle (the “Early Mandatory Settlement”) the Purchase Contracts early, whether as components of the Units or Separate Purchase Contracts, in whole but not in part, on a date (the “Early Mandatory Settlement Date”) fixed by the Company at the Early Mandatory Settlement Rate. The “Early Mandatory Settlement Rate” is the Maximum Settlement Rate in effect immediately prior to the Close of Business on the third Business Day immediately preceding the date on which the Company provides the Early Mandatory Settlement Notice to the Purchase Contract Agent, the Trustee and the Holders (the “Early Mandatory Settlement Notice Date”) (such Business Day, the “Early Mandatory Relevant Date”), provided that, for the avoidance of doubt, the Early Mandatory Settlement Rate shall continue to be subject to adjustments as provided in Section 5.01 herein for any events described therein that occur prior to the Early Mandatory Settlement Date.

(b) If the Company elects to exercise its Early Mandatory Settlement Right, the Company shall provide the Purchase Contract Agent, the Trustee and the Holder 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 Web site. The Early Mandatory Settlement Notice shall specify:

(i) the applicable Early Mandatory Settlement Rate;

(ii) the Early Mandatory Settlement Date, which shall be at least 20 but not more than 35 Business Days following the Early Mandatory Settlement Notice Date (and which shall be required to fall on the Repurchase Date);

(iii) that 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, pursuant to and in accordance with the Indenture;

(iv) the Repurchase Price and Repurchase Date;

(v) the last date on which Holders may exercise their Repurchase Right;

(vi) the procedures that Holders must follow hereunder and under the Indenture to require the Company to repurchase their Notes;

(vii) if any outstanding Securities are Definitive Securities, the name and address of the Purchase Contract Agent; and

(viii) any other information the Company determines to be appropriate.

(c) In the event that the Early Mandatory Settlement Right is exercised with respect to Purchase Contracts that are a component of any Units, upon the relevant Early Mandatory Settlement Date, the Company shall execute and the Trustee shall authenticate (pursuant to the Indenture) on behalf of the Holder and deliver to the Holder thereof, at the expense of the Company, Separate Notes in the same form and in the same number as the Notes comprising part of such Units; provided, however, that if the Repurchase Date occurs prior to the Early Mandatory Settlement Date, any Holder exercising the Repurchase Right shall surrender the Units on the Repurchase Date and the Company shall execute, and the Purchase Contract Agent shall authenticate, Separate Purchase Contracts in the same form and in the same number as the Purchase Contracts comprising part of such Units, such Separate Purchase Contracts to be settled on the Early Mandatory Settlement Date.

Section 4.08. Acquisition Termination Redemption

(a) If the Acquisition Agreement has been terminated on or prior to June 1, 2017, the Company may elect to redeem all, but not less than all, of the Outstanding Purchase Contracts, on the terms described in this Section 4.08 (an “Acquisition Termination Redemption”), by delivering notice within the five Business Days immediately following the date of such termination (such notice, the “Acquisition Redemption Notice”) in the manner specified in Section 4.08(b).

(b) In the event of an Acquisition Termination Redemption, the Company shall provide the Purchase Contract Agent, the Trustee and the Holders of Units, Separate Purchase Contracts and Separate Notes with the Acquisition Redemption Notice, issue a press release announcing its election and post such press release on its website. The Acquisition Redemption Notice shall specify:

(i) the Acquisition Termination Stock Price;

(ii) the Scheduled Acquisition Redemption Settlement Date;

(iii) if the Redemption Amount will be determined pursuant to Section 4.08(c)(i), the Redemption Amount;

(iv) if the Redemption Amount will be determined pursuant to Section 4.08(c)(ii), the Acquisition Redemption Rate, and, if applicable, the number of shares of Common Stock that would otherwise be included in the applicable Redemption Amount that will be replaced with cash;

(v) that 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, pursuant to and in accordance with the Indenture;

(vi) the Repurchase Price and Repurchase Date;

(vii) the last date on which Holders may exercise their Repurchase Right;

(viii) the procedures that Holders must follow hereunder and under the Indenture to require the Company to repurchase their Notes;

(ix) if any outstanding Securities are Definitive Securities, the name and address of the Purchase Contract Agent; and

(x) any other information the Company determines to be appropriate.

If the Company does not specify a number of shares of Common Stock that will be replaced with cash in the Acquisition Redemption Notice, the Company shall be deemed to have elected to settle the Redemption Amount solely in shares.

(c) In the event of an Acquisition Termination Redemption, the Company shall deliver the applicable Redemption Amount on the Acquisition Redemption Settlement Date. The “Redemption Amount” shall mean:

(i) if the Acquisition Termination Stock Price is equal to or less than the Reference Price, an amount of cash per Purchase Contract equal to (x) the Unit Stated Amount less (y) the applicable Repurchase Price; or

(ii) if the Acquisition Termination Stock Price is greater than the Reference Price, a number of shares of Common Stock per Purchase Contract equal to the Acquisition Redemption Rate determined by reference to the table set forth in Section 4.08(e); provided that the Company may elect to pay cash in lieu of any or all of such shares of Common Stock in an amount equal to such number of shares multiplied by the Redemption Market Value; provided further that, if the Company so elects to pay cash, the Company shall specify in the Acquisition Redemption Notice the number of shares of Common Stock that will be replaced with cash.

The Company shall cause any shares referred to in clause (ii) above to be issued and delivered, together with payment of (a) any cash payable in lieu of fractional shares pursuant to Section 4.05 and (b) any dividends or distributions with respect to such shares constituting part of the Purchase Contract Settlement Fund (but without any interest thereon), to the applicable Holder by book-entry transfer or other appropriate procedures pursuant to Section 4.03. The Person in whose name any shares of the Common Stock shall be issuable pursuant to an Acquisition Termination Redemption shall become the holder of record of such shares as of the close of business: (x) on the date of the Acquisition Redemption Notice, if the Company has elected (or is deemed to have elected) to settle the Redemption Amount solely in shares of Common Stock, or (y) on the last Trading Day of the 20 consecutive Trading Day period used to determine the Redemption Market Value, if the Acquisition Termination Stock Price is greater than the Reference Price and the Company elects to pay cash in lieu of any but not all shares of Common Stock that would otherwise be included in the Redemption Amount.

(d) The table below sets forth the “Acquisition Redemption Rate” per Purchase Contract for each Acquisition Termination Stock Price and termination date. The Acquisition Termination Stock Prices set forth in the first column of the table below shall be adjusted as of any date on which the Fixed Settlement Rates are otherwise adjusted. The adjusted Acquisition Termination Stock Prices shall equal the Acquisition Termination Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the applicable Fixed Settlement Rate immediately prior to the adjustment giving rise to the Acquisition Termination Stock Price adjustment and the denominator of which is such Fixed Settlement Rate as so adjusted. The Acquisition Redemption Rates per Purchase Contract in the table in Section 4.08(e) shall be adjusted at the same time and in the same manner as the Fixed Settlement Rates as set forth in Section 5.01.

(e) The following table sets forth the Acquisition Redemption Rate per Purchase Contract for each Acquisition Termination Stock Price and termination date set forth below; provided, that if the applicable Acquisition Termination Stock Price is equal to or less than the Reference Price, the Acquisition Redemption Rate will be determined pursuant to Section 4.08(c)(ii):

	Acquisition Termination Stock Price
Termination date	$16.13	$18.00	$19.92	$25.00	$30.00	$35.00	$40.00	$50.00
June 21, 2016	5.3341	5.2758	5.2268	5.1359	5.0821	5.0488	5.0277	5.0201
October 1, 2016	5.3540	5.2917	5.2393	5.1425	5.0858	5.0512	5.0296	5.0201
January 1, 2017	5.3731	5.3067	5.2509	5.1480	5.0884	5.0527	5.0307	5.0201
April 1, 2017	5.3931	5.3222	5.2624	5.1529	5.0903	5.0535	5.0313	5.0201
July 1, 2017	5.4151	5.3387	5.2744	5.1571	5.0913	5.0534	5.0312	5.0201

The exact Acquisition Termination Stock Prices and termination date may not be set forth in the table above, in which case:

(i) if the applicable Acquisition Termination Stock Price is between two Acquisition Termination Stock Prices in the table or the termination date is between two termination dates in the table, the Acquisition Redemption Rate shall be determined by straight-line interpolation between the Acquisition Redemption Rates set forth for the higher and lower Acquisition Termination Stock Prices and the two termination dates, as applicable, based on a 365-day year; or

(ii) if the applicable Acquisition Termination Stock Price is in excess of $50.00 per share (subject to adjustment at the same time and in the same manner as the Acquisition Termination Stock Prices set forth in the table above), then the Acquisition Redemption Rate will be the Minimum Settlement Rate.

ARTICLE V ADJUSTMENTS

Section 5.01. Adjustments to the Fixed Settlement Rates.

(a) Each Fixed Settlement Rate shall be subject to the following adjustments:

(i) Stock Dividends and Distributions. If the Company exclusively issues shares of Common Stock as a dividend or other distribution on all or substantially all shares of Common Stock, or if the Company effects a share split or share combination, each Fixed Settlement Rate will be adjusted based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date of such dividend or distribution, or immediately prior to the Open of Business on the effective date of such share split or combination, as applicable;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Open of Business on such Ex-Dividend Date or such effective date, as applicable;

OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date or such effective date, as applicable; and

OS1	=	the number of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

Any adjustment made under this Section 5.01(a)(i) shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Section 5.01(a)(i) is declared but not so paid or made,

each Fixed Settlement Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the applicable Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared.

(ii) Issuance of Stock Purchase Rights. If the Company issues to all or substantially all holders of Common Stock rights any rights, options or warrants entitling them, for a period of not more than 60 days after the date of such issuance, to subscribe for or purchase shares of Common Stock, at a price per share less than the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, each Fixed Settlement Rate will be increased based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such issuance;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

OS0	=	the number of shares of Common Stock outstanding immediately prior to the Open of Business on such Ex-Dividend Date;

X	=	the total number of shares of Common Stock issuable pursuant to such rights, options or warrants; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Closing Prices of the Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 5.01(a)(ii) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the Open of Business on the Ex-Dividend Date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of Common Stock are not delivered upon the expiration of such rights, options or warrants, each Fixed Settlement Rate shall be readjusted to the applicable Fixed Settlement Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so issued, or if no such rights, options or warrants are exercised prior to their expiration, each Fixed Settlement Rate shall be decreased to be the applicable Fixed Settlement Rate that would then be in effect if such Ex-Dividend Date if such issuance had not occurred.

For purposes of this Section 5.01(a)(ii), in determining whether any rights, options or warrants entitle the holders of the Common Stock to subscribe for or purchase shares of Common Stock at a price per share less than such average of the Closing Prices of the Common Stock for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(iii) Asset or Debt Distribution. If the Company distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire shares of its Capital Stock or other securities, to all or substantially all holders of the Common Stock, excluding:

(A) dividends or distributions, rights options or warrants as to which an adjustment was effected pursuant to Section 5.01(a)(i) hereof or Section 5.01(a)(ii) hereof;

(B) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 5.01(a)(iv) hereof; and

then each Fixed Settlement Rate shall be increased based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such distribution;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

SP0	=	the average of the Closing Prices of Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the Fair Market Value of the shares of Capital Stock, evidences of indebtedness, other assets, or property of the Company or rights, options or warrants to acquire shares of the Company’s Capital Stock or other securities distributed with respect to each outstanding share of the Common Stock as of the Open of Business on the Ex-Dividend Date for such distribution.

If “FMV” (as defined above) is equal to or greater than the “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Unit and Separate Purchase Contract shall receive, in respect of each Unit and Separate Purchase Contract, as applicable, it holds, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of the Company’s Capital Stock, evidences of the Company’s indebtedness, other assets or property of the Company or rights, options or warrants to acquire Company’s Capital Stock or other securities that such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate in effect immediately prior to the Record Date for such distribution.

Any increase made under the portion of this Section 5.01(a)(iii) above shall become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution (including a Spin-Off as defined below) is not so paid or made, each Fixed Settlement Rate shall be decreased to be the applicable Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared. In the case of rights, options or warrants to acquire shares of the Company’s Capital Stock or other securities, to the extent that such rights, options or warrants are not exercised prior to their expiration or the Company’s Capital Stock or other securities are not delivered upon the expiration of such rights, options or warrants, each Fixed Settlement Rate shall be readjusted to the applicable Fixed Settlement Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the Company’s Capital Stock or other securities actually delivered. If such rights, options or warrants are not so issued, or if no such

rights, options or warrants are exercised prior to their expiration, each Fixed Settlement Rate shall be decreased to be the applicable Fixed Settlement Rate that would then be in effect if such issuance had not occurred.

With respect to an adjustment pursuant to this Section 5.01(a)(iii) where there has been a payment of a dividend or other distribution on the Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to any of the Company’s Subsidiaries or business units, and such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a U.S. national securities exchange or a reasonably comparable non-U.S. equivalent (a “Spin-Off”), the each Fixed Settlement Rate will be increased based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such Spin-Off;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such Spin-Off;

FMV0	=	the average of the Closing Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period after, but excluding, the effective date of the Spin-Off (the “Valuation Period”); and

MP0	=	the average of the Closing Prices of the Common Stock over the Valuation Period.

If the first VWAP Trading Day of the Observation Period applicable to the settlement of relevant Units or Separate Purchase Contracts, as the case may be, occurs after the first Trading Day of the Valuation Period for a Spin-Off, but on or before the last Trading Day of the Valuation Period for such Spin-Off, the reference in the above definition of “FMV0” to 10 consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the first Trading Day of the Valuation Period for such Spin-Off to, but excluding, the first VWAP Trading Day of such Observation Period. If one or more VWAP Trading Days of the Observation Period applicable to the settlement of the relevant Unit or Separate Purchase Contract, as the case may be, occurs on or after the Ex-Dividend Date for a Spin-Off but on or prior to the first Trading Day of the Valuation Period for such Spin-Off, such Observation Period will be suspended from, and including, the first such VWAP Trading Day to, and including, the first Trading Day of the Valuation Period for such Spin-Off and will resume immediately after the first Trading Day of the Valuation Period for such Spin-Off, with the reference in the above definition of “FMV0” to 10 consecutive Trading Days deemed replaced with a reference to one (1) Trading Day.

In addition, if an Early Settlement Exercise Date or the Early Mandatory Relevant Date occurs during the period from, but excluding, the first Trading Day of the Valuation Period for a Spin-Off to, and including, the last Trading Day of the Valuation Period for such Spin-Off, the reference in the above definition of “FMV0” to “10” consecutive Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the first Trading Day of the Valuation Period for such Spin-Off to, but excluding, the applicable Early Settlement Exercise Date or Early Mandatory Relevant Date, as applicable. If an Early Settlement Exercise Date or Early Mandatory Relevant Date occurs during the period from, and including, the Ex-Dividend Date of a Spin-Off to, and including, the first Trading Day of the Valuation Period for such Spin-Off, (i) the reference in the above definition of “FMV0” to “10” consecutive Trading Days shall be deemed replaced with a reference to “one (1)” Trading Day, (ii) the Company shall deliver the consideration due to such Holder in respect of the applicable Early

Settlement or Early Mandatory Settlement, as applicable on the third Business Day after the first Trading Day of the Valuation Period for such Spin-Off, (iii) the relevant Fixed Settlement Rates, Early Mandatory Settlement Rate and Fundamental Change Early Settlement Rate, as the case may be, applicable to such Early Settlement or Early Mandatory Settlement, as applicable, shall be such respective Fixed Settlement Rates or Fundamental Change Early Settlement Rate in effect immediately prior to the Close of Business on the first Trading Day of the Valuation Period for such Spin-Off and (iv) the person in whose name any shares of Common Stock shall be issuable in respect of the applicable Early Settlement or Early Mandatory Settlement, as applicable, shall be deemed to become the holder of record of such shares as of the Close of Business on the first Trading Day of the Valuation Period for such Spin-Off.

For purposes of the second adjustment set forth in this Section 5.01(a)(iii), (i) the Closing Price of any Capital Stock or similar equity interest shall be calculated by the Company in a manner analogous to that used to calculate the Closing Price of the Common Stock in the definition of “Closing Price” set forth in Section 1.01 hereof, (ii) whether a day is a Trading Day (and whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for such Capital Stock or similar equity interest shall be determined in a manner analogous to that used to determine whether a day is a Trading Day (or whether a day is a Scheduled Trading Day and whether a Market Disruption Event has occurred) for the Common Stock, and (iii) whether a day is a Trading Day to be included in a Valuation Period will be determined based on whether a day is a Trading Day for both the Common Stock and such Capital Stock or similar equity interest.

(iv) Cash Distributions. If the Company pays any cash dividends or distributions to all or substantially all holders of the Common Stock, each Fixed Settlement Rate shall be increased based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Open of Business on the Ex-Dividend Date for such dividend or distribution;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution;

SP0	=	the Closing Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

C	=	the amount in cash per share that the Company distributes to holders of the Common Stock.

If “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing increase, each Holder of a Unit or a Separate Purchase Contract shall receive, for each such Unit or a Separate Purchase Contract it holds, as the case may be, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Maximum Settlement Rate in effect immediately prior to the Close of Business on the Record Date for such cash dividend or distribution.

Such increase shall become effective immediately after the Open of Business on the Ex-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, each Fixed Settlement Rate shall be decreased to be the applicable Fixed Settlement Rate that would then be in effect if such dividend or distribution had not been declared.

(v) Self Tender Offers and Exchange Offers. If the Company or any of its Subsidiaries make a payment in respect of a tender offer or exchange offer made by the Company or any of its Subsidiaries for the Common Stock, to the extent that the cash and value of any other consideration included in the payment

per share of the Common Stock exceeds the Closing Price of the 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 “Tender Offer Expiration Date”), each Fixed Settlement Rate shall be increased based on the following formula:

where,

FR0	=	the applicable Fixed Settlement Rate in effect immediately prior to the Close of Business on the Tender Offer Expiration Date;

FR1	=	the applicable Fixed Settlement Rate in effect immediately after the Close of Business on the Tender Offer Expiration Date;

AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors) paid or payable for shares of Common Stock purchased in such tender offer or exchange offer;

OS0	=	the number of shares of Common Stock outstanding immediately prior to the expiration time of the tender or exchange offer on the Tender Offer Expiration Date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);

OS1	=	the number of shares of Common Stock outstanding immediately after the expiration time of the tender or exchange offer on the Tender Offer Expiration Date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and

SP1	=	the average of the Closing Prices of the Common Stock over the 10 consecutive Trading Day period commencing on, and including, the Trading Day next succeeding the Tender Offer Expiration Date (the “Averaging Period”).

If the first VWAP Trading Day of the Observation Period applicable to the settlement of relevant Unit or Separate Purchase Contract, as the case may be, occurs after the first Trading Day of the Averaging Period for a tender or exchange offer, but on or before the last Trading Day of the Averaging Period for such tender or exchange offer, the reference in the above definition of “ SP1” to “10” shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the first Trading Day of the Averaging Period for such tender or exchange offer to, but excluding, the first VWAP Trading Day of such Observation Period. If one or more VWAP Trading Days of the Observation Period applicable to the settlement of the relevant Unit or Separate Purchase Contract, as the case may be, occurs on or after the Tender Offer Expiration Date for a tender or exchange offer but on or prior to the first Trading Day of the Averaging Period for such tender or exchange offer, such Observation Period will be suspended from, and including, the first such VWAP Trading Day to, and including, the first Trading Day of the Averaging Period for such tender or exchange offer and will resume immediately after the first Trading Day of the Averaging Period for such tender or exchange offer, with the reference in the above definition of “SP1” to “10” consecutive Trading Days deemed replaced with a reference to “one (1)”.

In addition, if an Early Settlement Exercise Date or Early Mandatory Relevant Date occurs during the period from, but excluding, the first Trading Day of the Averaging Period for a tender or exchange offer to, and including, the last Trading Day of the Averaging Period for such tender or exchange offer, the reference in the above definition of “SP1” to “10” shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the first Trading Day of the Averaging Period for such tender or exchange offer to, but excluding, the applicable Early Settlement Exercise Date or Early Mandatory Relevant Date, as applicable. If an Early Settlement Exercise Date or Early Mandatory

Relevant Date occurs during the period from, but excluding, the Tender Offer Expiration Date to, and including, the first Trading Day of the Averaging Period for such tender or exchange offer, (i) the reference in the above definition of “SP1” to “10” shall be deemed replaced with a reference to “one (1)”, (ii) the Company shall deliver the consideration due to such Holder in respect of the applicable Early Settlement or Early Mandatory Settlement, as applicable, on the third Business Day after the first Trading Day of the Averaging Period for such tender or exchange offer, (iii) the relevant Fixed Settlement Rates, Early Mandatory Settlement Rate and Fundamental Change Early Settlement Rate, as the case may be, applicable to such Early Settlement or Early Mandatory Settlement, as applicable, will be such respective Fixed Settlement Rates, Early Mandatory Settlement Rate or Fundamental Change Early Settlement Rate in effect immediately prior to the Close of Business on the first Trading Day of the Averaging Period for such tender or exchange offer and (iv) the person in whose name any shares of Common Stock shall be issuable in respect of the applicable Early Settlement or Early Mandatory Settlement, as applicable, will be deemed to become the holder of record of such shares as of the Close of Business on the first Trading Day of the Averaging Period for such tender or exchange offer.

(vi) Special Settlement Provisions.

(A) Notwithstanding anything to the contrary herein, if a Fixed Settlement Rate adjustment becomes effective on any Ex-Dividend Date, and (x) a Holder of a Unit or a Separate Purchase Contract that has elected Early Settlement of such Unit or such Separate Purchase Contract, as applicable for which the applicable Early Settlement Exercise Date occurs or (y) a holder of a Unit or a Separate Purchase Contract to which Early Mandatory Settlement applies and for which the applicable Early Mandatory Relevant Date occurs, in either case of clauses (x) or (y), on or after such Ex-Dividend Date and on or prior to the related Record Date would be (i) treated as the record holder of shares of Common Stock as of the related Early Settlement Exercise Date or Early Mandatory Relevant Date, as applicable, pursuant to Section 3.02 based on a Fixed Settlement Rate that would otherwise be adjusted for such Ex-Dividend Date in respect of such dividend, distribution or other event giving rise to such adjustment and (ii) entitled to participate in the related dividend, distribution or other event giving rise to such adjustment with respect to all such shares of Common Stock, then, notwithstanding the foregoing Fixed Settlement Rate adjustment provisions, the Fixed Settlement Rate adjustment relating to such Ex-Dividend Date will not be made for such Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(B) In addition, if:

(1) the Record Date, effective date or Tender Offer Expiration Date for any event that requires an adjustment to the Fixed Settlement Rates under any of Sections 5.01(a)(i) through (v) hereof occurs:

(a) on or after the first VWAP Trading Day of the relevant Observation Period; and

(b) on or prior to the last VWAP Trading Day of such Observation Period; and

(2) the Daily Settlement Amount for any VWAP Trading Day in such Observation Period that occurs on or prior to such Record Date, effective date or Tender Offer Expiration Date:

(a) includes shares of Common Stock that do not entitle their holder to participate in such event; and

(b) is calculated based on a Fixed Settlement Rate that is not adjusted on account of such event;

then the Company shall treat each Holder of a Unit or Separate Purchase Contract as though it were the record holder on such Record Date, effective date or Tender Offer Expiration Date, as applicable, of a number of shares of Common Stock per Unit or Separate Purchase Contract, as applicable, equal to the total number of shares of Common Stock that:

(1) are deliverable as part of the Daily Settlement Amount:

(a) for a VWAP Trading Day in such Observation Period that occurs on or prior to such Record Date, effective date or Tender Offer Expiration Date; and

(b) that is calculated based on a Fixed Settlement Rate that is not adjusted for such event; and

(2) if not for this provision, would not entitle such Holder to participate in such event.

(vii) Rights Plans. Upon Settlement of a Unit or a Separate Purchase Contract, to the extent that the Company then has a rights plan with respect to the Common Stock in effect, if (i) Early Settlement applies to such Unit or Separate Purchase Contract, on the applicable Early Settlement Exercise Date, (ii) Early Mandatory Settlement applies to such Unit or Separate Purchase Contract, on the applicable Early Mandatory Relevant Date or (iii) Mandatory Settlement applies to such Unit or Separate Purchase Contract, on any VWAP Trading Day in the relevant Observation Period, in each case, the Holders thereof shall receive from the Company, in addition to any shares of Common Stock received in connection with such Early Settlement or Early Mandatory Settlement or in respect of such VWAP Trading Day, as the case may be, the rights under the rights plan, unless, prior to such Early Settlement Exercise Date, Early Mandatory Relevant Date or VWAP Trading Day, as the case may be, the rights have separated from the Common Stock, in which case each Fixed Settlement Rate shall be adjusted at the time of separation of such rights as if the Company made a distribution to all holders of the Common Stock that is subject to Section 5.01(a)(iii), subject to readjustment in the event of the expiration, termination or redemption of such rights.

(viii) Limitation on Adjustments. Except as stated in this Section 5.01(a), the Company shall not adjust the Fixed Settlement Rates for the issuance of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or the right to purchase shares of Common Stock or such convertible or exchangeable securities. If the application of the formulas in Sections 5.01(a)(i) through (v) would result in a decrease in the Fixed Settlement Rates, then, except to the extent of any readjustment to the Fixed Settlement Rates, no adjustment to the Fixed Settlement Rates will be made (other than as a result of a reverse share split or share combination).

(b) Adjustment for Tax Reasons. The Company may make such increases in each Fixed Settlement Rate, in addition to any other increases required by this Section 5.01, to avoid or diminish any income tax to holders of shares of Common Stock or rights to purchase shares of Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights or warrants to acquire shares of Common Stock) or from any event treated as such for U.S. federal income tax purposes or for any other reasons; provided, however, that the same proportionate adjustment must be made to each Fixed Settlement Rate.

(i) All adjustments to each Fixed Settlement Rate shall be calculated to the nearest 1/10,000th of a share of Common Stock. Adjustments to Threshold Appreciation Price, Reference Price and Stock Price shall be calculated to the nearest $0.0001.

(ii) Upon each adjustment to each Fixed Settlement Rate, and as of the time of such adjustment, each of the Threshold Appreciation Price and the Reference Price in effect immediately prior to

such adjustment shall be multiplied by a fraction, the numerator of which shall be the Fixed Settlement Rate in effect immediately before such adjustment, and the denominator of which shall be such Fixed Settlement Rate in effect immediately after such adjustment.

(iii) If an adjustment is made to the Fixed Settlement Rates pursuant to Section 5.01(a) or Section 5.01(b), then, as of the time of such adjustment, an adjustment shall be made to each Stock Price set forth in the column headers of the table included in Section 5.02(e) by multiplying such Stock Price by a fraction, the numerator of which shall be the Fixed Settlement Rate in effect immediately before such adjustment, and the denominator of which shall be such Fixed Settlement Rate in effect immediately after such adjustment. Each of the Fundamental Change Early Settlement Rates in the table included in Section 5.02(e) will be subject to adjustment in the same manner as each Fixed Settlement Rate as set forth in this Section 5.01.

(iv) Notwithstanding anything herein to the contrary, no adjustment to the Fixed Settlement Rates (or, for the avoidance of doubt, any corresponding adjustment to the Reference Price or Threshold Reference Price pursuant to Section 5.01(c)) shall be made if Holders participate (other than in the case of a share split or share combination) at the same time and upon the same terms as holders of shares of Common Stock and as a result of holding the Units or Separate Purchase Contracts, as applicable, in any of the transactions that would otherwise give rise to an adjustment without having to settle their Purchase Contracts as if they held a number of shares of the Common Stock equal to the then applicable Maximum Settlement Rate multiplied by the number of Units or Separate Purchase Contracts, as applicable, held by such Holders. In addition, the Fixed Settlement Rates shall not be adjusted:

(A) on account of stock repurchases that are not tender offers referred to in Section 5.01(a)(v), including structured or derivative transactions, or transactions pursuant to a stock repurchase program approved by the Board of Directors, or otherwise;

(B) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock under any plan;

(C) upon the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Company or any of its Subsidiaries;

(D) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (C) above and outstanding as of the Issue Date; or

(E) for a change in the par value of the Common Stock.

(d) Notice of Adjustment. If the Company adjusts the Fixed Settlement Rates, the Company shall deliver to the Purchase Contract Agent an Officer’s 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, upon which certificate the Purchase Contract Agent may conclusively rely. In addition, the Company shall issue a press release containing the relevant information (and make such information available on its Web site). The Purchase Contract Agent shall not be responsible for, and shall not make any representation as to the validity or value of, any share of Common Stock, securities or assets issued upon settlement of the Units or Separate Purchase Contracts, or as to the accuracy of any calculation made hereunder. The Purchase Contract Agent shall have no duty or obligation to calculate a Fixed Settlement Rate or any adjustment thereto or verify any calculation thereof.

(e) Reorganization Events. In the event of:

(i) any recapitalization, reclassification or change of the Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a split, subdivision or combination for which an adjustment is made pursuant to Section 5.01(a)(i));

(ii) any consolidation or merger, amalgamation or combination involving the Company;

(iii) any sale, lease or other transfer to another Person (other than the Company and any of its Subsidiaries) of the consolidated assets of the Company and its Subsidiaries substantially as an entirety; or

(iv) any binding exchange of securities of the Company with another Person (other than in connection with a merger or acquisition covered by clause (i) above),

and, in each case, as a result of which the Common Stock would be converted into, or exchanged for, common stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Merger Event” and such common stock, securities, property or assets (including cash or any combination thereof), the “Reference Property” and the amount of Reference Property that a holder of one share of the Common Stock would be entitled to receive on account of such Merger Event, an “Reference Property Unit”), then, at the effective time of the applicable Merger Event, the right to settlement of each Unit or Separate Purchase Contract into shares of Common Stock will be changed into a right to settlement of such Unit or Separate Purchase Contract based on the kind and amount of Reference Property that a holder of shares of Common Stock would have owned or been entitled to receive upon such Merger Event. However, at and after the effective time of the Merger Event, (i) any number of shares of Common Stock that the Company would have been required to deliver upon settlement or redemption of the Units and Separate Purchase Contracts as set forth above will instead be deliverable in the amount and type of Reference Property that a holder of that number of shares of Common Stock would have received in such Merger Event, (ii) the Daily VWAP and Closing Price will be calculated based on the value of a Reference Property Unit and (iii) the consideration due upon settlement of the Units and Separate Purchase Contracts will be determined as if relevant references to shares of Common Stock or any number thereof (including for purposes of any adjustment to the Fixed Settlement Rates) were deemed replaced with references to the components of a Reference Property Unit. If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the amount and type of Reference Property that a holder of one or more shares of Common Stock would have been entitled to receive in such Merger Event (and that will be deliverable upon settlement of the Units and Separate Purchase Contracts) shall be deemed to be based on the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election. The Company shall notify Holders of the weighted average as soon as reasonably practicable after such determination is made.

Notwithstanding anything to the contrary herein, for so long as the Units or Separate Purchase Contracts remain outstanding, the Company will not become a party to any agreement providing for a Merger Event if the terms of such agreement relative to the treatment of the Units or Separate Purchase Contracts are inconsistent with the provisions described in this Section 5.01(e), unless the Purchase Contracts are to be settled (including pursuant to an Early Mandatory Settlement) prior to consummation of such Merger Event.

The above provisions of this Section 5.01(e) shall similarly apply to successive Merger Events. Following each Merger Event, (i) for the avoidance of doubt, the Fixed Settlement Rates (together with corresponding adjustments to the Fundamental Change Settlement Rates, the Stock Prices, the Reference Price and the Threshold Appreciation Price) shall be subject to adjustments which will be as nearly equivalent as may be practicable, as determined by the Board of Directors in its commercially reasonable judgment, to the adjustments provided for in this Section 5.01 (except that no such adjustments shall be required with respect to any portion of a Reference Property Unit that does not consist of Capital Stock); and (ii) for all purposes hereunder (including, without limitation, for purposes of determining whether a Fundamental Change has occurred), each reference herein to Common Stock shall be read as if such reference were instead a reference to the Reference Property Units.

Section 5.02. Early Settlement Upon a Fundamental Change

(a) If a Fundamental Change occurs and a Holder elects to effect an Early Settlement of any Purchase Contract in connection with such Fundamental Change, then, notwithstanding anything to the contrary herein, such Holder shall receive a number of shares of Common Stock (or Reference Property Units, as applicable) 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 Company and the Purchase Contract Agent, and otherwise satisfies the requirements for effecting Early Settlement of its Purchase Contracts set forth in Section 4.04, during the period beginning on, and including, the Effective Date of the Fundamental Change and ending on, and including, the 45th Business Day thereafter (the “Fundamental Change Early Settlement Period”).

If a Holder complies with the requirements set forth in Section 5.02(b) to exercise the Fundamental Change Early Settlement Right prior to the Close of Business on any Business Day during the Fundamental Change Early Settlement Period, then that Business Day shall be considered the “Fundamental Change Early Settlement Date.” If a Holder complies with the requirements set forth in Section 5.02(b) to exercise the Fundamental Change Early Settlement Right at or after the Close of Business on any Business Day during the Fundamental Change Early Settlement Period or at any time on a day during the Fundamental Change Early Settlement Period that is not a Business Day, then the next succeeding Business Day shall be considered 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 the Company’s Web site. The notice shall set forth, among other things:

(i) the applicable Fundamental Change Early Settlement Rate;

(ii) the kind and amount of cash, securities and other property receivable by the Holder upon settlement;

(iii) the deadline by which each Holder’s Fundamental Change Early Settlement Right must be exercised;

(iv) that 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, pursuant to and in accordance with the Indenture;

(v) the Repurchase Price and Repurchase Date;

(vi) the last date on which Holders may exercise their Repurchase Right; and

(vii) the procedures that Holders must follow hereunder and under the Indenture to require the Company to repurchase their Notes.

(c) The “Fundamental Change Early Settlement Rate” shall be determined 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 determined as follows:

(i) in the case of a Fundamental Change described in sub-clause (A) or (B) of 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 Closing Prices per share of Common Stock over the 10 consecutive Trading Day period ending on, and including, the Trading Day preceding the Effective Date.

(d) The Stock Prices set forth in the column headers of the table below and the Fundamental Change Early Settlement Rates in the table below are subject to adjustment as provided in Section 5.01(c).

(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:

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

(i) if the applicable Stock Price is between two Stock Prices in the table or the applicable Effective Date is between two Effective Dates in the table, then the Fundamental Change Early Settlement Rate shall be determined by a straight-line interpolation between the Fundamental Change Early Settlement Rates set forth for the higher and lower Stock Prices and the two Effective Dates surrounding the applicable Stock Price or Effective Date, as applicable, based on a 365-day year;

(ii) if the applicable Stock Price is in excess of $50.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the table above), then the Fundamental Change Early Settlement Rate shall be the Minimum Settlement Rate; or

(iii) if the applicable Stock Price is less than $4.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the table above) (the “Minimum Stock Price”), then 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 5.02(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 6.1996, subject to adjustment as provided in Section 5.01.

(f) The Company shall deliver shares of Common Stock or Reference Property Units, as applicable, deliverable as a result of a Holder’s exercise of the Fundamental Change Early Settlement Right on or prior to 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 or the Early Mandatory Settlement Date or upon Mandatory Settlement or redemption on any subsequent Acquisition Redemption Settlement Date, including, if applicable, the provisions set forth in Section 5.01.

Section 5.03. Adjustments of Prices.

Whenever any provision of this Purchase Contract Agreement requires the Company to calculate the Closing Prices, the Daily VWAPs or any function thereof over a span of multiple days (including during an Observation Period), the Company shall make appropriate adjustments to each to account for any adjustment to the Fixed Settlement Rates that becomes effective, or any event requiring an adjustment to the Fixed Settlement Rates where the effective date, Ex-Dividend Date or Tender Offer Expiration Date of the event occurs, at any time during the period when such Closing Prices, the Daily VWAPs or function thereof are to be calculated.

For the avoidance of doubt, the adjustments made pursuant to the foregoing paragraph, to the extent any such adjustments are necessary, will be made without duplication of any adjustment made pursuant to Section 5.01(a)(vi)(B).

Section 5.04. Tax Withholding.

By purchasing a beneficial interest in a Purchase Contract (whether or not included in a Unit), each Holder, and any individual or entity that acquires a direct or indirect interest in the Purchase Contract (whether or not included in a Unit), will be deemed to have agreed that if the Company or other applicable withholding agent pays withholding taxes or backup withholding on behalf of a Holder or beneficial owner of a Purchase Contract (whether or not included in a Unit) as a result of an adjustment of, or failure to make an adjustment of, the Fixed Settlement Rate, the Company or other applicable withholding agent may, at its option, set off such payments against payments of cash or Common Stock payable on the sale or settlement of a Purchase Contract (whether or not included in a Unit) or, possibly, against any payments on shares of Common Stock.

ARTICLE VI 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 (and/or, in the case of an Acquisition Termination Redemption, any cash included in the Redemption Amount), Reference Property or cash in lieu of any fractional share or Reference Property upon settlement of such Purchase Contract on the applicable Settlement Date and to institute suit for the enforcement of any such right to receive the shares of Common Stock (and/or, in the case of an Acquisition Termination Redemption, any cash included in the Redemption Amount), and such right shall not be impaired without the consent of such Holder.

Section 6.02. Limitation on Proceedings.

No Holder of Purchase Contracts (whether or not included in a Unit) may institute any proceedings, judicial or otherwise, with respect to this Purchase Contract 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 satisfactory to the Purchase Contract Agent. This provision will not prevent any Holder of Purchase Contracts (whether or not included in a Unit) from instituting suit for the delivery of shares of Common Stock (and/or, in the case of an Acquisition Termination Redemption, any cash included in the Redemption Amount), Reference Property or cash in lieu of any fractional share or Reference Property upon settlement or redemption of the Purchase Contracts on the applicable 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 Purchase Contract 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 Purchase Contract 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 Purchase Contract 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, however, 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 10.0% of the Outstanding Purchase Contracts, or (c) any Holder for the enforcement of the right to receive shares of Common Stock, Reference Property or cash in lieu of any fractional share or Reference Property upon settlement or the Redemption Amount payable upon redemption, as the case may be, of 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 Purchase Contract 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 in number 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, however, that the Purchase Contract Agent has received indemnity satisfactory to it. Notwithstanding anything to the contrary in the foregoing, the Purchase Contract Agent may refuse to follow any direction that is in conflict with any law or this 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.

ARTICLE VII THE PURCHASE CONTRACT AGENT AND TRUSTEE

Section 7.01. Certain Duties and Responsibilities.

(ii) no provision of this Purchase Contract Agreement shall require the Purchase Contract Agent to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if indemnity satisfactory to the Purchase Contract Agent is not provided to it; and

(iii) the Purchase Contract Agent shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of a majority in number of the Outstanding Purchase Contracts.

Company and the Holders of Purchase Contracts, as their names and addresses appear in the Security Register, notice of such default hereunder, unless such Responsible Officer of the Purchase Contract Agent has actual knowledge that such default shall have been cured or waived.

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

(k) the rights, privileges, protections, immunities and benefits given to the Purchase Contract Agent and under this Purchase Contract Agreement, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee (whether or not the Trustee is expressly referred for in connection with any such rights, privileges, protections, immunities and benefits) and to each agent, custodian and other Person employed to act hereunder;

(l) in no event shall either of the Purchase Contract Agent or the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Purchase Contact Agent or the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; and

(m) neither the Purchase Contract Agent nor the Trustee shall be responsible for delays or failures in performance of its obligations hereunder because of circumstances beyond its control, including, but not limited to, acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed after the fact, fire, communication line failures, computer viruses, power failures, earthquakes, terrorist attacks or other disasters, it being understood that each of the Purchase Contract Agent and the Trustee shall use reasonable best efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances;

Section 7.10. Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Purchase Contract Agent, every such successor Purchase Contract Agent so appointed shall execute, acknowledge and deliver to the Company and to the retiring Purchase Contract Agent an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Purchase Contract Agent shall become effective and such successor Purchase Contract Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Purchase Contract Agent, and the retiring Purchase Contract Agent shall have no further obligations or duties hereunder except as expressly set forth herein. At the request of the Company or the successor Purchase Contract Agent, such retiring Purchase Contract Agent shall, upon its receipt of payment or reimbursement of any amounts due to it hereunder, execute and deliver an instrument transferring to such successor Purchase Contract Agent all the rights, powers and trusts of the retiring Purchase Contract Agent and shall duly

assign, transfer and deliver to such successor Purchase Contract Agent all property and money held by such retiring Purchase Contract Agent hereunder.

(b) Upon request of any such successor Purchase Contract Agent, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Purchase Contract Agent all such rights, powers and agencies referred to in paragraph Section 7.10(a).

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

Section 7.11. Merger; Conversion; Consolidation or Succession to Business.

Any corporation into which the Purchase Contract Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Purchase Contract Agent shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Purchase Contract Agent, shall be the successor of the Purchase Contract Agent hereunder; provided, however, that such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. If any Equity-Linked Securities shall have been authenticated on behalf of the Holders by the Trustee and Purchase Contract Agent then in office, but not delivered, any successor by merger, conversion or consolidation to such Purchase Contract Agent may adopt such Purchase Contract Agent’s authentication and deliver the Equity-Linked Securities so authenticated with the same effect as if such successor Purchase Contract Agent had itself authenticated such Equity-Linked Securities.

Section 7.12. Preservation of Information; Communications to Holders.

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

Section 7.13. No Other Obligations of Purchase Contract Agent or Trustee.

Except to the extent otherwise expressly provided in this Purchase Contract Agreement, neither the Purchase Contract Agent nor Trustee assumes any obligations, and neither the Purchase Contract Agent nor Trustee shall be subject to any liability, under this Purchase Contract Agreement or Security evidencing a Unit or Purchase Contract in respect of the obligations to the Holder of any Unit or Purchase Contract thereunder. The Company agrees, and each Holder of a Security, by his or her acceptance thereof, shall be deemed to have agreed, that the Purchase Contract Agent’s or Trustee’s authentication, as applicable, of the Securities on behalf of the Holders shall be solely as agent and attorney-in-fact for the Holders, and that neither the Purchase Contract Agent nor Trustee shall have any obligation to perform such Purchase Contracts (whether held as components of Units or Separate Purchase Contracts) on behalf of the Holders. Anything contained in this Purchase Contract Agreement to the contrary notwithstanding, in no event shall the Purchase Contract Agent, the Trustee or their respective officers, employees or agents be liable under this Purchase Contract Agreement to any third party for indirect, special, punitive, or consequential loss or damage of any kind whatsoever, including lost profits, whether or not the likelihood of such loss or damage was known to the Purchase Contract Agent or Trustee, incurred without any act or deed that is found to be attributable to gross negligence or willful misconduct on the part of the Purchase Contract Agent or Trustee.

Section 7.14. Tax Compliance.

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

(b) The Company shall provide written direction to the Purchase Contract Agent with respect to its obligations arising under Section 7.14(a). The Purchase Contract Agent shall comply, in accordance with the terms hereof, with any such written direction or any other written direction received from the Company with respect to the execution or certification of any required documentation and the application of such requirements to particular payments or Holders or in other particular circumstances, and may for purposes of this Purchase Contract Agreement conclusively rely on any such direction in accordance with the provisions of Section 7.01(a)(ii) hereof.

(c) The Purchase Contract Agent shall maintain all appropriate records documenting compliance with such requirements, and shall make such records available, on written request, to the Company or its authorized representative within a reasonable period of time after receipt of such request. For the avoidance of doubt, any costs or expenses incurred by the Purchase Contract Agent in connection with complying with its obligations under this Section 7.14 shall be covered by Section 7.07.

With the consent of the Holders of a majority in principal amount of the Outstanding Purchase Contracts (including without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for,

Units and/or Separate Purchase Contracts) and by Act of said Holders delivered to the Company and the Purchase Contract Agent, the Company, when authorized by a Board Resolution, and the Purchase Contract Agent may enter into a purchase contract agreement or purchase contract agreements supplemental hereto for the purpose of adding any provisions to, changing in any manner or eliminating any of, or waiving compliance to any of the provisions of this Purchase Contract Agreement or of modifying in any manner the rights of the Holders under this Purchase Contract Agreement and the Purchase Contracts; provided, however, that no such supplemental purchase contract agreement shall, without the consent of each Holder of the Outstanding Purchase Contracts affected thereby:

Section 8.06. Notice of Supplemental Agreements.

After any supplemental purchase contract agreement under this Article becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental purchase contract agreement; provided, however, that the failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of such supplemental purchase contract agreement.

The Company shall maintain in the continental United States an office or agency where Securities may be presented or surrendered for acquisition of shares of Common Stock (and/or, in the case of an Acquisition Termination Redemption, any cash included in the Redemption Amount) upon settlement or redemption of the Purchase Contracts on the Mandatory Settlement Date or any Early Settlement Exercise Date and where notices and demands to or upon the Company in respect of the Purchase Contracts and this Purchase Contract Agreement may be served.

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 continental United States for such purposes. The Company shall 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 10.05. Company to Reserve Common Stock.

The Company shall reserve and keep available out of its authorized and unissued Common Stock, solely for issuance upon settlement or redemption 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, assuming settlement at the Maximum Number of Shares set forth in Section 5.02(e), subject to adjustment as set forth hereto.

Section 10.06. Covenants as to Common Stock.

The Company covenants that all shares of Common Stock that may be issued upon settlement or redemption of any Outstanding Purchase Contract shall, upon issuance, be newly issued shares or treasury shares, be issued in book-entry format held through DTC, be duly authorized, validly issued, fully paid and nonassessable, free from all taxes, liens and charges (other than those created by the Holder or due to a change in registered owner) 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 or redemption of the Purchase Contracts, subject to official notice of issuance; 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 or redemption of Purchase Contracts in accordance with the provisions of this Purchase Contract Agreement, the Company covenants to list such Common Stock issuable upon settlement or redemption of the Purchase Contracts in accordance with the requirements of such exchange at such time.

[REVERSE OF NOTE]

DYNEGY INC.

This Amortizing Note is one of a duly authorized series of Securities of the Company designated as its 7.00% Senior Amortized Notes due 2019 (herein sometimes referred to as the “Notes”), issued under the indenture, dated as of June 21, 2016, between the Company and Wilmington Trust, National Association, as trustee (the “Trustee,” which term includes any successor trustee under the Indenture) (the “Base Indenture”) as supplemented by the First Supplemental Indenture, dated as of June 21, 2016, between the Company and the Trustee (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates, issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that securities of a single series may be issued at various times, with different maturity dates and may bear interest at different rates. This series of Securities is limited in aggregate principal amount as specified in the Supplemental Indenture.

Each Installment Payment shall constitute a payment of interest (at a rate of 7.00% per annum) and a partial repayment of principal on the Note, allocated as set forth in the schedule below:

Scheduled Installment Payment Date	Amount of Principal per Note		Amount of Interest per Note

April 1, 2019	$	1.69032		$	0.05968
July 1, 2019	$	1.71990		$	0.03010

Notwithstanding the foregoing, the amount of any Installment Payment for any Installment Payment Period shall be increased by the amount of additional interest, if any, payable for such Installment Payment Period as provided in the Indenture.

The Notes shall not be subject to redemption at the option of the Company, and no sinking fund is provided for the Notes. However, a Holder shall have the right to require the Company to repurchase some or all of its Notes for cash at the Repurchase Price per Note, and on the Repurchase Date, upon the occurrence of certain events, and subject to the conditions set forth in the Indenture.

This Note is not entitled to the benefit of any sinking fund. The Indenture contains provisions for legal defeasance and covenant defeasance at any time of the Indenture and this Note upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

If an Event of Default with respect to the Notes shall occur and be continuing, then (unless no declaration of acceleration or notice is required for such Event of Default) either the Trustee or the Holders of not less than 25% in principal amount of the Notes then outstanding may declare all future, scheduled Installment Payments to be due and payable immediately, in the manner, subject to the conditions and with the effect provided in the Indenture.

A-12

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee, with the consent of the holders of a majority in principal amount of the Notes at the time outstanding, to execute supplemental indentures for certain purposes as described therein.

Obligations Unconditional. No provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay Installment Payments on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

Additional Terms. The Notes are originally being issued as part of the Company’s 7.00% Tangible Equity Units (the “Units”) issued pursuant to that certain Purchase Contract Agreement, dated as of June 21, 2016, between the Company and Wilmington Trust, National Association, as Purchase Contract Agent and as Trustee of the Indenture (the “Purchase Contract Agreement”). Holders of the Units have the right to separate such Units into their constituent parts, consisting of Separate Purchase Contracts (as defined in the Purchase Contract Agreement) and Separate Notes, during the times, and under the circumstances described in the Purchase Contract Agreement. Following separation of any Unit into its constituent Separate Purchase Contract and Separate Note, the Separate Notes are transferable independently from the Separate Purchase Contracts. In addition, Separate Notes can be recombined with Separate Purchase Contracts to recreate Units, as provided for in the Purchase Contract Agreement. Reference is hereby made to the Purchase Contract Agreement for a more complete description of the terms thereof applicable to the Units and Notes.

Transfer and Exchange. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note shall be registered on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or agency of the Company in the continental United States, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or by his or her attorney duly authorized in writing, and thereupon the Company shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Note or Notes in authorized denominations and for a like aggregate principal amount.

The Notes are initially issued in registered, global form without coupons in denominations initially equal to $18.94911 and integral multiples in excess thereof.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or other similar governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Issuer or the Trustee may treat the Holder in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Note and the Indenture, and any claim, controversy or dispute arising under or related to the Indenture or this Note, shall be governed by, and construed in accordance with, the laws of the State of New York.

All terms used in this Note which are defined in the Indenture and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

No recourse shall be had for the payment of any Installment Payment on this Note, or for any claim based hereon, or upon any obligation, covenant or agreement of the Company in the Indenture, against any incorporator, stockholder, officer or director, past, present or future of the Company or of any predecessor or successor corporation, either directly or through the Company or of any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released and waived as a condition of, and as part of the consideration for, the issuance of this Note.

A-13

The Company, each Holder and each Beneficial Owner (for U.S. federal income tax purposes) by its acquisition of a beneficial interest in the Notes agrees, for U.S. federal income tax purposes, to treat the Notes as indebtedness of the Company.

A copy of the Indenture is available for inspection at the office of the Trustee.

In the event of any inconsistency between the provisions of this Note and the provisions of the Indenture, the Indenture shall prevail.
