The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 calendar days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment, and not less than 10 calendar days after the receipt by the Trustee of the notice of the proposed payment.

Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so sent, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the Close of Business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c).

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of the Indenture.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated (upon receipt of a Company Order) and delivered or disposed of as though the Person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such Persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Supplemental Indenture or the Base Indenture any such Person was not such an Officer.

Such Register shall be in written form or in any form capable of being converted into written form within a reasonable period of time. The Trustee is hereby appointed the Registrar for the purpose of registering Notes and transfers of Notes as provided in the Indenture. The Company may appoint one or more co-Registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Registrar or any co-Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by the Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall, upon receipt of a Company Order, authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

14

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or conversion shall (if so required by the Company, the Trustee, the Registrar or any co-Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and duly executed, by the Holder thereof or its attorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or any Paying Agent for any exchange or registration of transfer of Notes, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or other similar governmental charge required by law or permitted pursuant to Section 12.02(e) or Section 12.02(f).

None of the Company, the Trustee, the Registrar or any co-Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article XIII.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with the Indenture shall be the valid and binding obligations of the Company, evidencing the same debt, and entitled to the same benefits under the Indenture as the Notes surrendered upon such registration of transfer or exchange.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.05(a) shall apply to the Notes in lieu of Section 2.08 of the Base Indenture.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law, subject to the fifth paragraph of this Section 2.05(b) all Notes shall be represented by one or more Notes in global form (each, a “ Global Note ”) registered in the name of the Depositary or a nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with the Indenture and the procedures of the Depositary therefor.

Notwithstanding anything to the contrary in the Indenture or the Notes, a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(b).

15

The Depositary shall be a clearing agency registered under the Exchange Act. The Company appoints DTC to act as initial Depositary with respect to each Global Note. Each Note to be issued on the date hereof shall initially be issued in the form of one or more Global Notes, and each such Global Note shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for Cede & Co. Neither the Trustee nor any agent shall have any responsibility or liability for any actions taken or not taken by the Depositary.

Transfers and exchanges of the Notes will be effected through the Depositary in accordance with the Applicable Procedures.

Unless the Company and the beneficial owner of the relevant Note agree otherwise, if, and only if, (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 calendar days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 calendar days, or (iii) an Event of Default with respect to the Notes has occurred and is continuing and a beneficial owner of any Note requests that its beneficial interest therein be issued as a Physical Note, the Company shall execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver (x) in the case of clause (iii), a Physical Note to such beneficial owner in a principal amount equal to the principal amount of such Note corresponding such beneficial owner’s beneficial interest and (y) in the case of clause (i) or (ii), Physical Notes to each beneficial owner of the related Global Notes (or a portion thereof) in an aggregate principal amount equal to the aggregate principal amount of such Global Notes in exchange for such Global Notes, and upon delivery of the Global Notes to the Trustee such Global Notes shall be canceled.

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(b) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Physical Notes to the Persons in whose names such Physical Notes are so registered.

At such time as all interests in a Global Note have been converted, canceled, repurchased or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is exchanged for Physical Notes, converted, canceled, repurchased or transferred to a transferee who receives Physical Notes therefor or any Physical Note is exchanged or transferred for part of such Global Note, the principal amount of such Global Note shall, in accordance with standing procedures and existing instructions between the Depositary and the Custodian, be appropriately reduced or increased, as the case may be, and an endorsement shall be made on the Schedule of Exchanges of such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.

None of the Company, the Trustee nor any agent of the Company or the Trustee shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

16

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global Notes) 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, the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements of the Indenture.

Section 2.06 Mutilated, Destroyed, Lost or Stolen Notes . In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request by Company Order, the Trustee or an authenticating agent appointed by the Trustee shall, upon receipt of a Company Order, authenticate and deliver a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case, the applicant for a substituted Note shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate upon receipt of a Company Order any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Registrar, any co-Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or is about to be converted in accordance with Article XII shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

17

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) the Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment or conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding (to the extent prohibited by the same) any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or conversion of negotiable instruments or other securities without their surrender.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 2.06 shall apply to the Notes in lieu of Section 2.09 of the Base Indenture.

Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under the Indenture as Physical Notes authenticated and delivered hereunder.

All Notes delivered to the Trustee shall be canceled in accordance with its customary procedures, and no Notes shall be authenticated in exchange thereof except as expressly permitted by any of the provisions of the Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver a certificate of such disposition to the Company, at the Company’s written request in a Company Order. If the Company or any of its Subsidiaries shall acquire any of the Notes, such acquisition shall not operate as a

Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters required by Section 12.05 of the Base Indenture and that the form and terms of such Notes has been established in conformity with the provisions of the Indenture and that such Notes, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, fair dealing and unconscionability), regardless of whether considered in a proceeding in equity or law. In addition, the Company may, to the extent permitted by law, and directly or indirectly (regardless of whether such Notes are surrendered to the Company), repurchase Notes in the open market or otherwise, whether by the Company or its Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case without prior notice to the Holders. Any Notes repurchased by the Company (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) shall be surrendered to the Trustee for cancellation in accordance with Section 2.08, but shall not be reissued or resold by the Company and shall no longer be considered outstanding upon their repurchase.

If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Company), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04), by written notice to the Company (and to the Trustee if given by Holders), may, and the Trustee, at the written request of such Holders, shall, declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, notwithstanding anything to the contrary in the Notes or the Indenture.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, and if (1) rescission would not conflict with any judgment or decree of a

25

court of competent jurisdiction and (2) any and all existing Events of Default under the Indenture with respect to the Notes, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of a majority in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of the Indenture with respect to the Notes; but no such rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary in the Indenture or the Notes, no such rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase Notes when required, (iii) a failure to pay or deliver, as the case may be, the Conversion Settlement Consideration due upon conversion of the Notes or (iv) any other provision that requires the consent of each affected Holder to amend.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.02 shall apply to the Notes in lieu of Section 6.02 of the Base Indenture.

Section 6.03 Additional Interest in Lieu of Reporting Default . Notwithstanding anything to the contrary in the Indenture or the Notes, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 4.04(a) or its obligation set forth in Section 314(a)(1) of the Trust Indenture Act (such obligations, collectively, “ Reporting Obligations ”) shall, for the first 180 calendar days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes outstanding for each day during the first 90 calendar days after the occurrence of such Event of Default and (ii) 0.50% per annum of the principal amount of the Notes outstanding from, and including, the 91 ^st calendar day through, and including, the 180 ^th calendar day following the occurrence of such Event of Default, during which such Event of Default is continuing. Such Additional Interest, if any, shall accrue from, and including, the date on which such an Event of Default first occurs. If the Company duly so elects, such Additional Interest shall be payable in the same manner and on the same dates as regular interest on the Notes. On the 181 ^st calendar day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with the Reporting Obligations is not cured or waived prior to such 181 ^st calendar day), the Notes will be subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Additional Interest following an Event of Default in accordance with this Section 6.03 or the Company elects to make such payment but does not pay the Additional Interest when due, the Notes shall be subject to acceleration as provided in Section 6.02.

In order to elect to pay Additional Interest as the sole remedy during the first 180 calendar days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such 180-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as

26

provided in Section 6.02. Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.03 shall not affect the rights of Holders in the event of the occurrence of any Event of Default other than an Event of Default relating to the Company’s failure to comply with the Reporting Obligations.

Section 6.04 Payments of Notes on Default; Suit Therefor . If an Event of Default described in clause (a) or (b) of Section 6.01 shall have occurred, the Company shall pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount of principal and interest, if any, then due and payable on the Notes, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.07 of the Base Indenture. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon the Notes, wherever situated.

All rights of action and of asserting claims under the Indenture with respect to the Notes, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of the Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the Holders, and it shall not be necessary to make any Holders parties to any such proceedings.

In case the Trustee shall have proceeded to enforce any right under the Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then, and in every such case, the Company, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.05 Priorities . Any monies collected by the Trustee pursuant to this Article VI or Article Six of the Base Indenture with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies:

First, to the payment of all amounts due the Trustee and its agents and attorneys under the Base Indenture;

27

Second, to the Holders, for any amounts due and unpaid on the principal (including the Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest on, and any cash Conversion Settlement Consideration due upon the conversion of, any Note, without preference or priority of any kind, according to such amounts due and payable on all of the Notes; and

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.05 shall apply to the Notes in lieu of Section 6.12 of the Base Indenture.

Section 6.06 Proceedings by Holders . Except to enforce the right to receive payment of principal (including, if applicable, the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the Conversion Settlement Consideration due upon conversion, no Holder of any Note shall have any right by virtue of or by availing of any provision of the Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to the Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy under the Indenture, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made a written request to the Trustee to pursue such remedy hereunder;

(c) such Holders shall have offered to the Trustee such security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee, for 60 calendar days after its receipt of the request and offer of security or indemnity, shall not complied with such request; and

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of a majority of the aggregate principal amount of the Notes then outstanding within such 60-day period pursuant to Section 6.09, it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder, and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders), or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under the Indenture, except in the manner provided in the Indenture and for the equal, ratable and common benefit of all Holders (except as otherwise provided in the Indenture). For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding anything to the contrary in the Indenture or the Notes, the right of any Holder of any Note to receive payment or delivery, as the case may be, of (x) the principal (including the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the Conversion Settlement Consideration due upon conversion of, such Note, on or after the respective due dates expressed or provided for in such Note or in the Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against the Company shall not be impaired or affected without the consent of such Holder.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.06 shall apply to the Notes in lieu of Sections 6.07 and 6.08 of the Base Indenture.

Section 6.07 Proceedings by Trustee . In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by the Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in the Indenture or in aid of the exercise of any power granted in the Indenture, or to enforce any other legal or equitable right vested in the Trustee by the Indenture or by law.

Section 6.08 Remedies Cumulative and Continuing . All powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in the Indenture, and no delay or omission of the Trustee or of any Holder to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.09 Direction of Proceedings and Waiver of Defaults by Majority of Holders . The Holders of a majority of the aggregate principal amount of the Notes at the time outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Notes; provided , however , that such direction shall not be in conflict with any rule of law or with the Indenture, and the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. The Holders of a majority in aggregate principal amount of the Notes at the time outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04) may on behalf of the Holders of all of the Notes waive any past Default or Event of

29

Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured pursuant to the provisions of Section 6.02, (ii) a failure by the Company to pay or deliver, as the case may be, the Conversion Settlement Consideration due upon conversion of the Notes or (iii) a default in respect of a covenant or provision of the Indenture that, under Article IX, cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Trustee and the Holders of the Notes shall be restored to their former positions and rights under the Indenture; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and the Indenture be deemed to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 6.09 shall apply to the Notes in lieu of Sections 6.04 and 6.05 of the Base Indenture.

Section 6.10 Undertaking to Pay Costs . All parties to the Indenture agree, and each Holder of any Note by its acceptance thereof 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 the Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, 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 expenses, 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 6.10 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, or to any suit instituted by any Holder for the enforcement of the payment of the principal (including the Fundamental Change Repurchase Price, if applicable) of, or accrued and unpaid interest, if any, on any Note on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to convert any Note in accordance with the provisions of Article XII.

Section 9.02 Supplemental Indentures with Consent of Holders . With the consent (evidenced as provided in Article VIII) of the Holders of at least a majority of the aggregate principal amount of Notes then outstanding (determined, for the avoidance of doubt, in accordance with Section 8.04 and including consents obtained in connection with a repurchase of, or tender or exchange offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense, may from time to time and at any time enter into an indenture or indentures supplemental hereto or amend the Notes for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or any supplemental indenture or of modifying in any manner the rights of the Holders; provided , however , that, without the consent of each Holder of an outstanding Note affected, no such supplemental indenture shall:

(a) reduce the amount of Notes whose Holders must consent to an amendment or waiver;

(b) reduce the rate of or extend the stated time for payment of interest on any Note;

(c) reduce the principal of or extend the Maturity Date of any Note;

(d) make any change that adversely affects the conversion rights of any Notes;

(e) reduce the Fundamental Change Repurchase Price of any Note or amend or modify in any manner adverse to the Holders the Company’s obligation to offer to repurchase and repurchase the Notes, whether through an amendment or waiver of provisions in the covenants, definitions or otherwise;

(i) make any change in this Article IX or the Notes that requires each Holder’s consent or in the waiver provisions in Section 6.02 or Section 6.09, if such change adversely affects the rights of the Holders.

Upon the written request of the Company, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid and subject to Section 12.05 of the Base Indenture, the Trustee shall join with the Company in the execution of such supplemental indenture or amendment unless such supplemental indenture or amendment affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental indenture or amendment.

35

Holders do not need, under this Section 9.02, to approve the particular form of any proposed supplemental indenture or amendment to the Notes. It shall be sufficient if such Holders approve the substance thereof. After any such supplemental indenture or amendment becomes effective, the Company shall mail to the Holders a notice briefly describing such supplemental indenture or amendment. However, the failure to give such notice to all the Holders, or any defect in the notice, will not impair or affect the validity of the supplemental indenture or amendment.

Section 9.03 Effect of Supplemental Indentures . Upon the execution of any supplemental indenture or amendment to the Notes pursuant to the provisions of this Article IX, the Indenture and the Notes shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitation of rights, obligations, duties and immunities under the Indenture and the Notes of the Trustee, the Company and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture or amendment shall be and be deemed to be part of the terms and conditions of the Indenture and the Notes for any and all purposes.

Section 9.04 Evidence of Compliance of Supplemental Indenture to Be Furnished to Trustee . In addition to the documents required by Section 12.05 of the Base Indenture, the Trustee shall receive, and shall be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such supplemental indenture or amendment is authorized or permitted by the Indenture, and an Opinion of Counsel in accordance with Section 12.05 of the Base Indenture and stating that such supplemental indenture or amendment complies with the requirements of this Article IX and is permitted or authorized by the Indenture. Such Opinion of Counsel will also state that such supplemental indenture or amendment is a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general application affecting the rights and remedies of creditors and to general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, fair dealing and unconscionability), regardless of whether considered in a proceeding in equity or law.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Article X shall apply to the Notes in lieu of Article Five of the Base Indenture.

Section 10.01 Company May Consolidate, Etc. on Certain Terms . Subject to the provisions of Section 10.02, the Company shall not consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to another Person, unless:

(a) the resulting, surviving or transferee Person (the “ Successor Company ”), if not the Company, shall be a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, all of the obligations of the Company under the Notes and the Indenture;

36

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture; and

(c) the Trustee shall have received an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article X.

For the avoidance of doubt, a Maryland real estate investment trust that has a class of Capital Stock classified as “common stock” or “common shares of beneficial interest” shall, for purposes of this Article X, be deemed to be a “corporation.”

Section 10.02 Successor Corporation to Be Substituted . In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment or delivery, as applicable, of the principal of and accrued and unpaid interest on, and the Conversion Settlement Consideration with respect to, all of the Notes, and the due and punctual performance of all of the covenants and conditions of the Indenture to be performed by the Company, such Successor Company (if not the Company) shall succeed to and, except in the case of a lease, shall be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in the Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under the Indenture as the Notes theretofore or thereafter issued in accordance with the terms of the Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article X the Person named as the “Company” in the first paragraph of this Supplemental Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article X) may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Notes and from its obligations under the Indenture with respect to the Notes and under the Notes.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Notwithstanding anything to the contrary in the Indenture or the Notes, this Section 11.01 shall apply to the Notes in lieu of Section 6.15 of the Base Indenture.

ARTICLE XII

C ONVERSION OF N OTES

Section 12.01 Conversion Privilege . Subject to and upon compliance with the provisions of this Article XII, each Holder of a Note shall have the right, at such Holder’s option, to convert all or any portion (if the portion to be converted is $1,000 principal amount or an integral multiple thereof) of such Note, at any time prior to the Close of Business on the second Scheduled Trading Day immediately preceding the Maturity Date into Conversion Settlement Consideration in the manner provided in, and subject to, this Article XII.

Section 12.02 Conversion Procedure; Settlement Upon Conversion .

(a) Settlement Method. Upon the conversion of any Note, the Company shall settle such conversion by paying or delivering, as applicable and as provided in this Article XII, either (A) solely cash (a “ Cash Settlement ”); (B) shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in the proviso to Section 12.02(b) (a “ Physical Settlement ”); or (C) a combination of cash and shares of Common Stock, together, if applicable, with cash in lieu of fractional shares as provided in Section 12.02(b) (a “ Combination Settlement ”). The Company shall have the right to elect the Settlement Method applicable to any conversion of a Note; provided , however , that:

(i) all conversions of Notes whose Conversion Date occurs on or after December 15, 2018 will be settled using the same Settlement Method, and the Company shall send written notice of such Settlement Method, through the Conversion Agent, to Holders no later than December 15, 2018;

(ii) the Company shall use the same Settlement Method for all conversions of Notes whose Conversion Dates occur on the same day (and, for the avoidance of doubt, the Company shall not be obligated to use the same Settlement Method with respect to conversions of Notes whose Conversion Dates occur on different days, except as provided in clause (i) above);

38

(iii) if the Company elects a Settlement Method with respect to the conversion of any Note whose Conversion Date occurs before December 15, 2018, the Company shall send written notice of such Settlement Method to the Holder of such Note, through the Conversion Agent, no later no later than the Close of Business on the Trading Day immediately following such Conversion Date;

(iv) if the Company does not timely elect a Settlement Method with respect to the conversion of a Note, then the Company will be deemed to have elected Combination Settlement with a Specified Dollar Amount per $1,000 principal amount of such Note equal to $1,000; and

(v) if the Company timely elects Combination Settlement with respect to the conversion of a Note but does not timely notify the Holder of such Note of the Specified Dollar Amount, then the Specified Dollar Amount for such conversion will be deemed to be $1,000 per $1,000 principal amount of such Note.

(b) Conversion Settlement Consideration . The type and amount of consideration (the “ Conversion Settlement Consideration ”) due in respect of each $1,000 principal amount of a Note to be converted shall be as follows:

(i) if Physical Settlement applies to such conversion, a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date for such conversion;

(ii) if Cash Settlement applies to such conversion, cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive Trading Days in the Observation Period for such conversion; or

(iii) if Combination Settlement applies to such conversion, a settlement amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive Trading Days in the Observation Period for such conversion;

provided , however , that if the total number of shares of Common Stock to be delivered with respect to the conversion of any Note is not a whole number, then the total number of shares so deliverable shall be rounded down to the nearest whole number and the Company shall deliver cash in lieu of the related fractional share in an amount equal to the product of such fraction and the Daily VWAP on the Conversion Date for such conversion (in the case of Physical Settlement) or the Daily VWAP on the last Trading Day of the Observation Period for such conversion (in the case of Combination Settlement).

The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional share of Common Stock, the Company shall notify the Trustee and the

39

Conversion Agent (if other than the Trustee) in writing of the Daily Settlement Amounts or the Daily Conversion Values, as the case may be, and the amount of cash payable in lieu of delivering fractional shares of Common Stock. The Trustee and the Conversion Agent (if other than the Trustee) shall have no responsibility for any such determination.

(c) Procedures to Convert a Note . Subject to Section 12.02(f), before any Holder of a Note shall be entitled to convert a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the Applicable Procedures of the Depositary in effect at that time (and any instruction to convert transmitted to the Depositary shall be irrevocable) and, if required, pay funds equal to interest payable on the next Interest Payment Date as set forth in Section 12.02(h) and (ii) in the case of a Physical Note (1) complete, manually sign and deliver a notice (which shall be irrevocable) to the Conversion Agent as set forth in the Form of Notice of Conversion (or a facsimile thereof) (a “ Notice of Conversion ”) at the office of the Conversion Agent and state in writing therein the principal amount of Notes to be converted (which must be an integral multiple of $1,000) and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any shares of Common Stock to be delivered upon settlement of the Conversion Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the office of the Conversion Agent, and (3) if required, pay funds equal to interest payable on the next Interest Payment Date as set forth in Section 12.02(h). The Trustee (and, if different, the Conversion Agent) shall notify the Company of any conversion pursuant to this Article XII on the Conversion Date for such conversion. No Notice of Conversion with respect to any Notes may be surrendered by a Holder thereof if such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 13.02.

If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered.

(d) Delivery of the Conversion Settlement Consideration . Subject to Section 12.03(b), Section 12.04(c), Section 12.04(e) and Section 12.06, the Company shall pay or deliver, as the case may be, the Conversion Settlement Consideration due in respect of the Conversion Obligation of a Note to be converted on the third Business Day immediately following the relevant Conversion Date (if the Company elects Physical Settlement) or on the third Business Day immediately following the last Trading Day of the relevant Observation Period (in the case of any other Settlement Method). If any shares of Common Stock are due to converting Holders, the Company shall issue or cause to be issued, and deliver to the Conversion Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of shares of Common Stock to which such Holder shall be entitled in satisfaction of the Company’s Conversion Obligation.

(e) Partial Conversions . In case any Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note,

40

without payment of any service charge by the converting Holder but, if required by the Company or the Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such conversion being different from the name of the Holder of the old Notes surrendered for such conversion.

(f) Taxes . If a Holder submits a Note for conversion, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of Common Stock upon conversion, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(g) Conversion of Global Notes . Upon the conversion of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any conversion of Notes effected through any Conversion Agent other than the Trustee.

(h) Treatment and Payment of Interest upon Conversion . Upon conversion of a Note, the Holder of such Note shall not receive any separate cash payment for accrued and unpaid interest, if any, on such Note, except as set forth below. The Company’s settlement of the related Conversion Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of such Note and accrued and unpaid interest, if any, on such Note to, but not including, the relevant Conversion Date. As a result, except as set forth below, accrued and unpaid interest, if any, to, but, not including, such Conversion Date shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of Notes into a combination of cash and shares of Common Stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. Notwithstanding the foregoing, if Notes are converted after the Close of Business on a Regular Record Date, Holders of such Notes as of the Close of Business on such Regular Record Date will receive the full amount of interest payable on such Notes on the corresponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period after the Close of Business on any Regular Record Date to the Open of Business on the immediately following Interest Payment Date must be accompanied by funds equal to the amount of interest payable, on such Interest Payment Date, on the Notes so converted; provided that no such payment shall be required (1) for conversions following the Regular Record Date immediately preceding the Maturity Date; (2) if the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (3) to the extent of any Defaulted Amounts, if any Defaulted Amounts exist at the time of conversion with respect to such Note. Therefore, for the avoidance of doubt, all Holders of record as of the Close of Business on the Regular Record Date immediately preceding the Maturity Date shall receive the full interest payment due on the Maturity Date regardless of whether their Notes have been converted following such Regular Record Date.

41

(i) Record Holders of Shares Due upon Conversion . If any Note is converted, the Person in whose name the certificate for any shares of Common Stock deliverable upon such conversion is to be registered shall be treated as a stockholder of record of such shares as of the Close of Business on the relevant Conversion Date (in the case of Physical Settlement) or as of the Close of Business on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement), as the case may be. Upon a conversion of Notes, such Person shall no longer be a Holder of such Notes surrendered for conversion.

Section 12.03 Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection with Make-Whole Fundamental Changes . (a) If the Effective Date of a Make-Whole Fundamental Change occurs prior to the Maturity Date and a Holder elects to convert any Note “in connection with” (as defined below) such Make-Whole Fundamental Change, the Company shall, under the circumstances set forth below, increase the Conversion Rate applicable to such Note by a number of additional shares of Common Stock (the “ Additional Shares ”), as set forth below. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion is received by the Conversion Agent from, and including, the Effective Date of the Make-Whole Fundamental Change up to, and including, the Business Day immediately prior to the related Fundamental Change Repurchase Date (or, in the case of a Make-Whole Fundamental Change that would have been a Fundamental Change but for subclause (x) of the proviso in clause (b) of the definition thereof, the 35th Trading Day immediately following the Effective Date of such Make-Whole Fundamental Change). For these purposes, the Conversion Agent will be deemed to have received the Notice of Conversion with respect to a Note on the Conversion Date with respect to such Note.

(b) Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change pursuant to this Section 12.03, the Company shall, at its option, satisfy the related Conversion Obligation by Physical Settlement, Cash Settlement or Combination Settlement in accordance with Section 12.02 based on the Conversion Rate as increased to reflect the Additional Shares pursuant to this Section 12.03; provided , however , that if, at the effective time of a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Reference Property following such Make-Whole Fundamental Change is composed entirely of cash, then, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Conversion Obligation shall be calculated based solely on the Stock Price for the transaction and shall be deemed to be an amount of cash per $1,000 principal amount of converted Notes equal to the applicable Conversion Rate (including any adjustment for Additional Shares), multiplied by such Stock Price. In such event, the Conversion Obligation will be determined and shall be paid to Holders in cash on the third Business Day following the Conversion Date. The Company shall notify the Holders of Notes of the Effective Date of any Make-Whole Fundamental Change no later than five Business Days after such Effective Date.

(c) The number of Additional Shares, if any, by which the Conversion Rate shall be increased shall be determined by reference to the table below, based on the date on which the Make-Whole Fundamental Change occurs or becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid (or deemed to be paid) per share of the Common Stock in the Make-Whole Fundamental Change. If the holders of the Common Stock receive in exchange for

42

their Common Stock only cash in a Make-Whole Fundamental Change described in clause (b) of the definition of Fundamental Change, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price shall be the average of the Last Reported Sale Prices of the Common Stock over the five Trading Day period ending on, and including, the Trading Day immediately preceding the Effective Date of the Make-Whole Fundamental Change.

(d) The Stock Prices set forth in the column headings of the table below shall be adjusted as of any date on which the Conversion Rate of the Notes is otherwise adjusted. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to such adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in the table below shall be adjusted in the same manner and at the same time as the Conversion Rate as set forth in Section 12.04.

(e) The following table sets forth the number of Additional Shares of Common Stock by which the Conversion Rate shall be increased per $1,000 principal amount of Notes pursuant to this Section 12.03 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 Stock Price is between two Stock Prices in the table above or the Effective Date is between two Effective Dates in the table above, the number of Additional Shares by which the Conversion Rate will be increased shall be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective Dates, as applicable, based on a 365- or 366-day year, as applicable;

(ii) if the Stock Price is greater than $22.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $16.42 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (d) above), no Additional Shares shall be added to the Conversion Rate.

Notwithstanding the foregoing, in no event will the Conversion Rate be increased pursuant to this Section 12.03 to exceed 60.9013 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 12.05.

43

(f) Nothing in this Section 12.03 shall prevent an adjustment to the Conversion Rate pursuant to Section 12.05 in respect of a Make-Whole Fundamental Change. For these purposes, if the Conversion Rate is to be adjusted in connection with a Make-Whole Fundamental Change pursuant to both Section 12.05 and this Section 12.03 with respect to any Note, then the adjustment pursuant to Section 12.05 shall be effected before any adjustment pursuant to this Section 12.03.

Section 12.04 Adjustments to the Conversion Rate . The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if each Holder participates (other than in the case of a stock split or stock combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 12.04, without having to convert its Notes, as if such Holder held a number of shares of Common Stock equal to the Conversion Rate multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company exclusively issues shares of Common Stock as a dividend or distribution on all or substantially all shares of Common Stock, or if the Company effects a stock split or stock combination, the Conversion Rate will be adjusted based on the following formula:

Any adjustment made under this Section 12.04(a) 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 stock split or stock combination, as applicable. If any dividend, distribution, stock split or stock combination of the type described in this Section 12.04(a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or effect such stock split or stock combination to the Conversion Rate that would then be in effect if such dividend or distribution or stock split or stock combination had not been declared or announced.

44

(b) If the Company issues to all or substantially all holders of Common Stock any rights, options or warrants (other than rights issued pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase shares of the Common Stock at a price per share that is less than the average of the Last Reported Sale 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, the Conversion Rate will be increased based on the following formula:

Any increase made under this Section 12.04(b) will 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 shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion 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, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For the purpose of this Section 12.04(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share price that is less than such average of the Last Reported Sale Prices for the 10

45

consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(c) 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 the Company’s Capital Stock or other securities, to all or substantially all holders of Common Stock, excluding:

(i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 12.04(a) or Section 12.04(b)

(ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 12.04(d);

(iii) cash dividends that do not result in an adjustment to the Conversion Rate pursuant to Section 12.03(d); and

(iv) Spin-Offs as to which the provisions set forth below in this Section 12.04(c) shall apply,

then the Conversion Rate will be increased based on the following formula:

Any increase made under the portion of this Section 12.04(c) above will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such

46

distribution is not so paid or made, or if any rights, options or warrants are not exercised before their expiration date, the Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such distribution had not been declared or on the basis of the rights, options or warrants actually exercised before their expiration date, as applicable. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), then, in lieu of the foregoing increase, each Holder shall receive, in respect of each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of the Common Stock, the amount and kind of such Capital Stock, evidences of indebtedness, other assets, property, rights, options or warrants that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the Conversion Rate in effect on the Record Date for such distribution.

With respect to an adjustment pursuant to this Section 12.04(c) where there has been a payment of a dividend or other distribution on Common Stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of the Company, and such Capital Stock or equity interest is, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “ Spin-Off ”), the Conversion Rate will be increased based on the following formula:

Any increase to the Conversion Rate under the preceding paragraph will be calculated as of the Close of Business on the last Trading Day of the Valuation Period but will be given effect as of immediately after the Open of Business on the Ex-Dividend Date of the Spin-Off. Because the Company will make the adjustment to the Conversion Rate with retroactive effect, the Company will delay the settlement of any conversion of Notes where the Conversion Date (in the case of Physical Settlement) or any Trading Day of the applicable Observation Period (in the

47

case of Cash Settlement or Combination Settlement) occurs during the Valuation Period until the third Business Day after the last day of the Valuation Period. If any distribution of the type described in this Section 12.04(c) is declared but not so made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such distribution had not been declared.

(d) If any cash dividend or distribution is made to all or substantially all holders of Common Stock, to the extent that the aggregate of all such cash dividends or distributions paid in any calendar quarter exceeds the Dividend Threshold Amount for such calendar quarter, the Conversion Rate will be adjusted based on the following formula:

The DTA is subject to adjustment on an inversely proportional basis whenever the Conversion Rate is adjusted, other than adjustments made pursuant to this Section 12.04(d).

Any increase to the Conversion Rate made pursuant to this Section 12.04(d) shall become effective immediately after the Open of Business on the Ex-Dividend Date for the dividend or distribution triggering such adjustment. If such dividend or distribution is not so paid, the Conversion Rate shall be readjusted, effective as of the date the Board of Directors determines not to make or pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP ₀ ” (as defined above), then, in lieu of the foregoing increase, each Holder shall receive, for each $1,000 principal amount of Notes, 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 Conversion Rate in effect on the Record Date for such cash dividend or distribution.

48

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender or exchange offer for Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of Common Stock exceeds the Last Reported Sale Price of Common Stock on the Trading Day next succeeding the last date (such last date, the “ Expiration Date ”) on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate will be increased based on the following formula:
