The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 principal amount and in integral multiples of $1,000 in excess thereof. Each Note shall be dated the date of its authentication and shall bear Interest from the date specified on the face of the form of Note attached as Exhibit A hereto. Interest on the Notes shall be computed on the basis of a 360-day year consisting of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the Close of Business on any Record Date with respect to any Interest Payment Date shall be entitled to receive the Interest payable on such Interest Payment Date, subject to the provisions of Section 13.02(a) relating to any Note or portion thereof surrendered for exchange during the period from the Close of Business on the Record Date for any Interest Payment Date to the Close of Business on the applicable Interest Payment Date. Interest on any Global Note shall be paid by wire transfer of immediately available funds to the account of the Depositary or its nominee. Payment of the principal of Notes not represented by a Global Note shall be made at the office or agency designated by the Issuer for such purpose. Interest on Notes not represented by a Global Note shall be paid (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Notes and (ii) to Holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Registrar not later than the relevant Record Date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

13

The term “ Record Date ” with respect to any Interest Payment Date shall mean the February 1 or August 1 preceding the applicable February 15 or August 15 Interest Payment Date, respectively.

Any Interest on any Note which is payable, but is not punctually paid or duly provided for, on any February 15 or August 15 (herein called “ Defaulted Interest ”) shall forthwith cease to be payable to the Noteholder registered as such on the relevant Record Date, and such Defaulted Interest shall be paid by the Issuer, at its election in each case, as provided in clause (a) or (b) below:

(a) The Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the Close of Business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 20 calendar days after the receipt by the Trustee of such notice), and at the same time the Issuer shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Interest 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 Interest as in this clause provided. Thereupon the Issuer shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 calendar days and not less than 10 calendar days prior to the date of the proposed payment. At least 15 calendar days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will mail or cause to be mailed to Holders (with a copy to the Trustee) a notice stating the special record date, the related payment date and the amount of such Interest to be paid to each such Holder.

(b) The Issuer may make payment of any Defaulted Interest 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 notice given by the Issuer to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.04. Execution of Notes . The Notes shall be signed in the name and on behalf of the Issuer by the manual or facsimile signature of an Officer. Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 7.11), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Issuer 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 this Indenture.

In case any Officer who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or

14

disposed of by the Issuer, such Notes nevertheless may be authenticated and delivered or disposed of as though the person who signed such Notes had not ceased to be such Officer, and any Note may be signed on behalf of the Issuer by such persons as, at the actual date of the execution of such Note, shall be the proper Officers, although at the date of the execution of this Indenture any such person was not such an Officer.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer . (a) The Issuer shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office and in any other office or agency of the Issuer designated pursuant to Section 4.02 being herein sometimes collectively referred to as the “ Note Register ”) in which, subject to such reasonable regulations as it may prescribe, the Issuer shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or in any form capable of being exchanged into written form within a reasonably prompt period of time. The Trustee is hereby appointed “ Note Registrar ” for the purpose of registering Notes and transfers of Notes as herein provided. The Issuer may appoint one or more co-registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Issuer shall execute, and the Trustee shall 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 this 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 Issuer pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and deliver, the Notes which the Noteholder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding.

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

All Notes presented or surrendered for registration of transfer or for exchange or repurchase shall (if so required by the Issuer or the Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Issuer and the Note Registrar, and the Notes shall be duly endorsed by the Noteholder thereof or its attorney duly authorized in writing.

No service charge shall be made to any Holder for any registration of, transfer or exchange of Notes, but the Issuer may require payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes.

15

(b) The following provisions shall apply only to Global Notes:

(i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or Custodian therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture.

(ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless (1) the Depositary (x) has notified the Issuer that it is unwilling or unable to continue as Depositary for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act, and a successor depositary has not been appointed by the Issuer within 90 calendar days, or (2) an Event of Default has occurred and is continuing and an election has been made to exchange such Notes. Any Global Note exchanged pursuant to clause (1) or (2) above shall be so exchanged in whole and not in part. Any Note issued in exchange for a Global Note or any portion thereof shall be a Global Note; provided that any such Note so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Note.

(iii) Notes issued in exchange for a Global Note or any portion thereof pursuant to clause (ii) above shall be issued in definitive, fully registered form, without Interest coupons, shall have an aggregate principal amount equal to that of such Global Note or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Note to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Note Registrar. With regard to any Global Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if the Trustee is acting as Custodian for the Depositary or its nominee with respect to such Global Note, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the Note issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof.

(iv) In the event of the occurrence of any of the events specified in clause (ii) above, the Issuer will promptly make available to the Trustee a reasonable supply of certificated Notes in definitive, fully registered form, without Interest coupons.

(v) Neither any members of, or participants in, the Depositary (“ Agent Members ”) nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Note registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be treated by the Issuer, the Trustee and any agent of the Issuer or the Trustee as the absolute owner and Holder of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee,

16

as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Note.

(vi) At such time as all interests in a Global Note have been repurchased, exchanged, or canceled for Notes in certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Custodian. At any time prior to such cancellation, if any interest in a Global Note is repurchased, exchanged, or canceled for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing between the Depositary and the Custodian, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the Custodian, at the direction of the Trustee, to reflect such reduction.

(c) Every Note (and all securities issued in exchange therefor or in substitution thereof) that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (the “ Restricted Notes Legend ”), and any Common Stock that bears or is required under this Section 2.05(c) to bear the Common Stock legend set forth in this Section 2.05(c) (the “ Common Stock Legend ”) (collectively, the “ Restricted Securities ”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those set forth in the legends below) unless such restrictions on transfer shall be waived by written consent of the Issuer, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c), the term “ transfer ” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

Until the Maturity Date for the Notes, every certificate evidencing the Notes shall bear a Restricted Notes Legend in substantially the following form unless otherwise determined by the Issuer in writing, with written notice thereof to the Trustee:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE ISSUER, EMPIRE STATE REALTY TRUST, INC. OR A SUBSIDIARY OF THE ISSUER; OR (B) TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE).

17

Until the date that is the later of (1) the date that is one year after the date of issuance of shares of Common Stock upon exchange of a Note, or such other period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such later date, if any, as may be required by applicable laws, any stock certificate evidencing shares of Common Stock issued upon exchange of such Note shall bear legends referring to the restrictions on ownership and transfer set forth in the Charter and a Common Stock Legend in substantially the following form unless such Common Stock has been sold pursuant to a registration statement that has been declared or become effective under the Securities Act (and which continues to be effective at the time of such transfer) or pursuant to Rule 144 under the Securities Act or any similar provision then in force, or unless otherwise determined by the Issuer in writing:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO EMPIRE STATE REALTY TRUST, INC. OR A SUBSIDIARY THEREOF; (B) UNDER A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT; (C) TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (2) THAT IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY, FURNISH TO THE TRANSFER AGENT AND EMPIRE STATE REALTY TRUST, INC. SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Any such shares of Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the Common Stock Legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the Common Stock Legend required by this Section 2.05(c).

(d) By its acceptance of any Note bearing the Restricted Notes Legend, each Holder of such Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it will transfer such Note only as provided in this Indenture and as permitted by applicable law.

18

(e) Any Restricted Securities purchased or owned by the Issuer or any Affiliate thereof may not be resold by the Issuer or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction which results in such Notes or Common Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).

(f) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Noteholders and all payments to be made to Noteholders under the Notes shall be given or made only to or upon the order of the registered Noteholders (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only through the Depositary subject to the customary procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members.

The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Agent Members in any Global Indenture).

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes . In case any Note shall become mutilated or be destroyed, lost or stolen, the Issuer in its discretion may execute, and upon its written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate and make available for delivery, a new Note, bearing a 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 Issuer, 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, the applicant shall also furnish to the Issuer, 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.

Following receipt by the Trustee or such authenticating agent, as the case may be, of satisfactory security or indemnity and evidence, as described in the preceding paragraph, the Trustee or such authenticating agent may authenticate any such substituted Note and make available for delivery such Note. Upon the issuance of any substituted Note, the Issuer may require the payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature or has been properly

19

tendered for repurchase on a Fundamental Change Repurchase Date (and not withdrawn) or is to be exchanged pursuant to this Indenture, shall become mutilated or be destroyed, lost or stolen, the Issuer may, instead of issuing a substitute Note, pay or authorize the payment of or exchange or authorize the exchange 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 exchange shall furnish to the Issuer, 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 in connection with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Issuer, the Trustee and, if applicable, any Paying Agent or Exchange Agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

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 Issuer, 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) this 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 exchange or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or exchange or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07. Temporary Notes . Pending the preparation of Notes in certificated form, the Issuer may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the Issuer, authenticate and deliver temporary Notes. Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Issuer. Every such temporary Note shall be executed by the Issuer 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 Notes in certificated form. Without unreasonable delay, the Issuer will execute and deliver to the Trustee or such authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Issuer pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Issuer 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 this Indenture as Notes in certificated form authenticated and delivered hereunder.

Section 2.08. Cancellation of Notes. All Notes surrendered for the purpose of payment, repurchase, exchange or registration of transfer shall, if surrendered to the Issuer or any paying agent to whom Notes may be presented for payment (the “ Paying Agent ”) or Exchange Agent, which shall initially be the Trustee, or any Note Registrar, be surrendered to the Trustee and promptly canceled by it or, if surrendered to the Trustee, shall be promptly canceled by it and no

20

Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of such canceled Notes in accordance with its applicable procedures. If the Issuer shall acquire any of the Notes, such acquisition shall not operate as a repurchase or satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

Section 2.09. CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to Holders as a convenience to such Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer shall promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

ARTICLE 3

REPURCHASE OF NOTES

Section 3.01. Redemption of Notes. The Notes shall be redeemable by the Issuer prior to the Maturity Date pursuant to Article 15. No sinking fund is provided for the Notes.

Section 3.02. Repurchase at Option of Holders Upon a Fundamental Change. (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, then each Noteholder shall have the right, at such Holder’s option, to require the Issuer to repurchase all of such Holder’s Notes, or any portion thereof that is a multiple of $1,000 principal amount, in cash, on a date (the “ Fundamental Change Repurchase Date ”) specified by the Issuer, which shall be no earlier than the 20th Business Day and no later than the 35th Business Day after the date of the Issuer Repurchase Notice related to such Fundamental Change, at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid Interest, if any, to, but excluding, the Fundamental Change Repurchase Date; provided, however, that if the Fundamental Change Repurchase Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer shall pay the full amount of accrued and unpaid Interest, if any, on such Interest Payment Date to the Holder of record at the Close of Business on the corresponding Record Date, and the repurchase price will be 100% of the principal amount of the Notes to be repurchased.

(b) Within 15 Business Days following the occurrence of a Fundamental Change, the Issuer will give or cause to be given to all Holders of record on the date of the Fundamental Change (and to beneficial owners as required by applicable law) an Issuer Repurchase Notice as set forth in Section 3.03 with respect to such Fundamental Change. The Issuer shall also deliver a copy of the Issuer Repurchase Notice to the Trustee and the Paying Agent at such time as it is given to Noteholders.

No failure of the Issuer to give the foregoing notices and no defect therein shall limit the Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.02.

21

(c) For a Note to be repurchased at the option of the Holder pursuant to this Section 3.02(c), the Holder must deliver to the Paying Agent, prior to the Close of Business on the second Business Day immediately preceding the Fundamental Change Repurchase Date, (i) a written notice of repurchase (the “ Fundamental Change Repurchase Notice ”) in the form set forth on the reverse of the Note duly completed (if the Note is certificated) or stating the following (if the Note is represented by a Global Note): (a) the certificate number of the Note that the Holder will deliver to be repurchased (if the Note is certificated) or that the relevant Fundamental Change Repurchase Notice complies with the appropriate Depositary procedures (if the Note is represented by a Global Note), (b) the portion of the principal amount of the Note which the Holder will deliver to be repurchased, which portion must be in minimum principal amounts of $1,000 or an integral multiple of $1,000 ( provided that the remaining principal amount of Notes not subject to repurchase must be in an authorized denomination) and (c) that such Note shall be repurchased as of the Fundamental Change Repurchase Date pursuant to the terms and conditions specified in the Note and in this Indenture; together with (ii) such Notes duly endorsed for transfer (if the Note if certificated) or book-entry transfer of such Note (if such Note is represented by a Global Note). The delivery of such Note to the Paying Agent with, or at any time after delivery of, the Fundamental Change Repurchase Notice (together with all necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by the Holder of the repurchase price therefore; provided , however , that such repurchase price shall be so paid pursuant to this Section 3.02 only if the Notes so delivered to the Paying Agent shall conform in all respects to the description thereof in the Fundamental Change Repurchase Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Note for repurchase shall be determined by the Issuer, whose determination shall be final and binding absent manifest error.

(d) The Issuer, if so requested, shall repurchase from the Holder thereof, pursuant to this Section 3.02, a portion of a Note, if the minimum principal amount of such portion is $1,000 or a whole multiple of $1,000. Provisions of this Indenture that apply to the repurchase of all of a Note also apply to the repurchase of such portion of such Note.

(e) Notwithstanding the foregoing, no Notes may be repurchased by the Issuer pursuant to this Section 3.02 if the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded or cured, on or prior to the relevant Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the repurchase price pursuant to this Section 3.02 with respect to the Notes to be repurchased).

(f) The Paying Agent shall promptly notify the Issuer of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof.

Any repurchase by the Issuer contemplated pursuant to the provisions of this Section 3.02 shall be consummated by the delivery of the consideration to be received by the Holder on the later of (i) a date within two Business Days after the book-entry transfer or delivery of the Notes to the Paying Agent and (ii) the Fundamental Change Repurchase Date. Payment of the repurchase price for a Note for which a Fundamental Change Repurchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer in compliance with applicable Depositary procedures or delivery of the Notes, together with necessary endorsements, to the Paying Agent.

22

Section 3.03. Issuer Repurchase Notice . (a) The Issuer Repurchase Notice, as provided in Section 3.03(b), shall be given to Holders in the event of a Fundamental Change, on or before the 15th Business Day after the occurrence of such a Fundamental Change as provided in Section 3.02(b) (the “ Issuer Repurchase Notice Date ”).

(b) In connection with any repurchase of Notes, the Issuer shall, on the applicable Issuer Repurchase Notice Date, give written notice to Holders (with a copy to the Trustee) setting forth information specified in this Section (in either case, the “ Issuer Repurchase Notice ”).

Each Issuer Repurchase Notice shall:

(i) state the events causing the Fundamental Change and the date thereof;

(ii) state the procedures Holders must follow to require the Issuer to purchase their Notes and that Holders must exercise their right to elect to repurchase prior to the Close of Business on the second Business Day immediately preceding the Fundamental Change Repurchase Date;

(iii) state the repurchase price, and the Fundamental Change Repurchase Date;

(iv) state the name and address of the Trustee, the Paying Agent and the Exchange Agent;

(v) state the applicable Exchange Rate and any adjustments thereto;

(vi) state that Notes must be surrendered to the Paying Agent to collect the repurchase price;

(vii) state that a Holder may withdraw its Fundamental Change Repurchase Notice at any time prior to the Close of Business on the second Business Day immediately prior to the Fundamental Change Repurchase Date by delivering a valid written notice of withdrawal in accordance with Section 3.04;

(viii) state that Notes as to which the Fundamental Change Repurchase Notice has been given may be exchanged only if the Fundamental Change Repurchase Notice is withdrawn in accordance with the terms of this Indenture;

(ix) state the amount of Interest accrued and unpaid per $1,000 principal amount of Notes to, but excluding, the Fundamental Change Repurchase Date;

(x) state that, unless the Issuer defaults in making payment of the repurchase price, Interest on Notes covered by any Fundamental Change Repurchase Notice shall cease to accrue on and after the Fundamental Change Repurchase Date;

23

(xi) state the CUSIP number of the Notes, if CUSIP numbers are then in use; and

(xii) if the Issuer determines that it will deduct and withhold from such amount otherwise deliverable to the Holder the amount required to be deducted and withheld under applicable law, the Issuer will include with the Issuer Repurchase Notice a notice of that determination and of its intent to withhold.

An Issuer Repurchase Notice may be given by the Issuer or, at the Issuer’s request, the Trustee shall give such Issuer Repurchase Notice in the Issuer’s name and at the Issuer’s expense; provided that the text of the Issuer Repurchase Notice shall be prepared by the Issuer.

If any of the Notes is represented by a Global Note, then the Issuer will modify such Issuer Repurchase Notice to the extent necessary to accord with the applicable procedures of the Depositary that apply to the repurchase of Global Notes.

Upon receipt by the Paying Agent of the Fundamental Change Repurchase Notice, the Holder of the Note in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Repurchase Notice is validly withdrawn in accordance with this Section 3.04) thereafter be entitled to receive solely the repurchase price with respect to such Note. Such repurchase price shall be paid to such Holder on the later of (x) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 3.02) and (y) two Business Days after the time of book-entry transfer or delivery of such Note to the Paying Agent by the Holder thereof in the manner required by Section 3.02 on or after the Fundamental Change Repurchase Date.

Notes in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be exchanged pursuant to Article 13 hereof on or after the date of the delivery of such Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn.

A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the office of the Paying Agent at any time prior to the Close of Business on the second Business Day immediately prior to the Fundamental Change Repurchase Date specifying:

Section 3.05. Deposit of Repurchase Price .

The Paying Agent shall have no duty to calculate the amount of cash sufficient to pay such aggregate repurchase price.

(b) If on the Fundamental Change Repurchase Date the Paying Agent holds money sufficient to pay the repurchase price of the Notes that Holders have elected to require the Issuer to repurchase in accordance with Section 3.02 and which have not been withdrawn in accordance with Section 3.04, then, on the Fundamental Change Repurchase Date such Notes will cease to be outstanding, Interest will cease to accrue and all other rights of the Holders of such Notes will terminate, other than the right to receive the repurchase price upon delivery or book-entry transfer of the Note. This will be the case whether or not book-entry transfer of the Note has been made or the Note has been delivered to the Paying Agent.

Section 3.06. Notes Repurchased in Part . Upon presentation of any Note repurchased only in part, the Issuer shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Issuer, a new Note or Notes in aggregate principal amount equal to the unrepurchased portion of the Notes presented (provided that the unrepurchased portion of the Notes must be in an integral multiple of $1,000).

Section 3.07. Repayment to the Issuer . Subject to Section 11.04, the Paying Agent shall return to the Issuer any cash that remains unclaimed, together with Interest, if any, thereon, held by them for the payment of the repurchase price; provided that to the extent that the aggregate amount of cash deposited by the Issuer pursuant to Section 3.05 exceeds the aggregate repurchase price of the Notes or portions thereof which the Issuer is obligated to repurchase as of the Fundamental Change Repurchase Date then, unless otherwise agreed in writing between the Issuer and the Paying Agent, promptly after the second Business Day following the Fundamental Change Repurchase Date, the Paying Agent shall return any such excess to the Issuer, together with Interest, if any, thereon.

25

Section 3.08. Repurchase by a Third Party .

Section 4.07. Stay, Extension and Usury Laws .

Section 4.08. Compliance Certificate . The Issuer and the Company will deliver to the Trustee, within 120 days after the end of each fiscal year, a brief certificate from the principal executive officer, principal financial officer or principal accounting officer of the Company as to his or her knowledge of the Issuer’s and the Company’s compliance with all conditions and covenants under this Indenture and, in the event of any noncompliance, specifying such noncompliance and the nature and status thereof.

The Issuer and the Company will deliver to the Trustee, within 30 days upon becoming aware of any default in the performance or observance of any covenant, agreement or condition contained in this Indenture an Officer’s Certificate specifying with particularity such default or Event of Default and further stating the nature and status thereof.

Section 4.11. Reservation of Shares, Shares to Be Fully Paid; Compliance with Governmental Requirements; Listing of Common Stock . The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of Common Stock to provide for the exchange of the Notes as required by this Indenture from time to time as such Notes are presented for exchange.

The Company covenants that all shares of Common Stock which may be issued upon exchange of Notes will upon issue be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof.

The Company further covenants that, if at any time the Common Stock shall be listed on the New York Stock Exchange or any other national or regional securities exchange or automated quotation system, the Company will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all the Common Stock issuable upon exchange of the Notes; provided that if the rules of such exchange or automated quotation system permit the Company to defer the listing of such the Common Stock until the first exchange of the Notes in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon exchange of the Notes in accordance with the requirements of such exchange or automated quotation system at such time.

Section 4.12. Covenant as to the Maturity Date During a Registration Default . If the Maturity Date, a Redemption Date or a Fundamental Change Repurchase Date for the Notes occurs and a Registration Default (as defined in the Registration Rights Agreement) exists on such date, in addition to any Additional Interest or Supplementary Interest otherwise payable, the Issuer will make a cash payment to each Holder of Notes of an amount equal to 3.0% of the principal amount of the Notes outstanding and held by such Holder as of the Close of Business on the third Scheduled Trading Day immediately prior to the Maturity Date, Redemption Date or Fundamental Change Repurchase Date, as applicable; provided, however , that no such amount shall be paid if the Issuer amends this Indenture prior to such date to irrevocably elect to settle exchanges of such Notes solely via Cash Settlement. For the avoidance of doubt, subject to the immediately preceding proviso, should the Maturity Date, the Redemption Date or Fundamental Change Repurchase Date occur during a period in which a Registration Default (as defined in the Registration Rights Agreement) exists, all record Holders of Notes outstanding on the third Scheduled Trading Day immediately preceding the Maturity Date, the Redemption Date or the Fundamental Change Repurchase Date, as applicable, will receive the cash payment specified in this paragraph regardless of whether their Notes have been exchanged on or after May 15, 2019 and prior to the Close of Business on such third Scheduled Trading Day preceding the Maturity Date, the Redemption Date or the Fundamental Change Repurchase Date, as applicable.

Section 4.13. Company Guarantee . The Company agrees to not incur any indebtedness for borrowed money or guarantee any of the Issuer’s indebtedness for borrowed money (in each

29

case other than Permitted Debt) without fully and unconditionally guaranteeing (subject to reasonable and customary exceptions) the Issuer’s obligations under this Indenture, including the due and punctual payment of principal of and Interest on the Notes, whether at Stated Maturity, by declaration of acceleration, notice of repurchase or otherwise; provided that the Company will be released from its obligations under such guarantee, and such guarantee will be terminated, to the extent the Company is subsequently no longer an obligor of indebtedness for borrowed money or a guarantor of any of Issuer’s indebtedness for borrowed money (in each case other than Permitted Debt). The guarantee will be a senior unsecured obligation of the Company and will rank equally in right of payment with other senior unsecured obligations of the Company.

(iii) consents to the appointment of any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy Law of it or for all or substantially of its property; or

(iii) orders the liquidation of the Company, the Issuer or any of their respective Significant Subsidiaries;

and, in each case in this clause (11), the order or decree remains unstayed and in effect for 90 calendar days;

then, and in each and every such case (other than an Event of Default specified in Section 6.01(a)(10) and Section 6.01(a)(11) with respect to the Issuer or 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, by notice in writing to the Issuer and the Company (and to the Trustee if given by Noteholders), may declare the principal amount of and Interest accrued and unpaid on all the Notes to be immediately due and payable, and upon any such declaration the same shall be immediately due and payable.

If an Event of Default specified in Section 6.01(a)(10) or Section 6.01(a)(11) occurs with respect to the Issuer or the Company and is continuing, then the principal amount of and Interest accrued and unpaid on all the Notes shall be immediately due and payable without any declaration or other action on the part of the Trustee or any Holder of Notes.

(b) Notwithstanding any provisions of this Indenture to the contrary, if the Issuer so elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with Section 5.04 hereof (a “ Reporting Event of Default ”), will consist exclusively of the right to receive additional interest on the Notes at a rate equal to (i) 0.25% per annum of the outstanding principal amount of the Notes for the first 180 days of the 270-day period in which such Event of Default is continuing beginning on, and including, the date on which such an Event of Default first occurs and (ii) 0.50% per annum of the outstanding principal amount of the Notes for the last 90 days of such 270-day period as long as such Event of Default is continuing (subject to Section 6.01(c), in addition to any Additional Interest that may be payable pursuant to the Registration Rights Agreement).

If the Issuer so elects, such additional interest will be payable in the same manner and on the same dates as the stated Interest payable on the Notes. On the 271st day after such Event of Default (if the Reporting Event of Default is not cured or waived prior to such 271st day), the Notes will be subject to acceleration pursuant to Section 6.01(a). The provisions of this Section 6.01(b) will not affect the rights of Holders of Notes in the event of the occurrence of any Event of Default that is not a Reporting Event of Default. In the event the Issuer does not

33

elect to pay the additional interest following a Reporting Event of Default in accordance with this Section 6.01(b) or the Issuer elected to make such payment but does not pay the additional interest when due, the Notes will be subject to acceleration as provided in Section 6.01(a).

In order to elect to pay the additional interest as the sole remedy during the first 270 days after the occurrence of a Reporting Event of Default, the Issuer must notify all Holders of Notes, the Trustee and the Paying Agent (if the Paying Agent is a Person other than the Trustee or the Issuer) of such election prior to the beginning of such 270-day period. Upon the Issuer’s failure to timely give such notice, the Notes will be subject to acceleration as provided in Section 6.01(a).

(c) In no event will the additional interest payable pursuant to Section 6.01(b) together with the Additional Interest payable pursuant to the Registration Rights Agreement (collectively, the “ Supplementary Interest ”) accrue at a rate in excess of 0.50% per annum pursuant to the Indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such Supplementary Interest.

(d) If, at any time after the principal amount of and Interest on 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, Holders of a majority in aggregate principal amount of the Notes then outstanding on behalf of the Holders of all of the Notes then outstanding, by written notice to the Issuer and to the Trustee, may waive all defaults or Events of Default and rescind and annul such declaration and its consequences, subject in all respects to Section 6.07, if: (a) all Events of Default, other than the nonpayment of the principal amount and any accrued and unpaid Interest that have become due solely because of such acceleration, have been cured or waived; (b) the Issuer or the Company shall have deposited with the Trustee a sum sufficient to pay all overdue Interest, including Interest on overdue installments of Interest (to the extent that payment of such Interest is lawful), and principal which has become due otherwise than by such declaration of acceleration; and (c) the Issuer has paid the Trustee its compensation and reimbursed the Trustee for its expenses (including any attorney’s reasonable fees), disbursements and advances pursuant to Section 7.06. 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.

(e) In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of such waiver or rescission and annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Issuer, the Holders of Notes, and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Issuer, the Holders of Notes, and the Trustee shall continue as though no such proceeding had been taken. Notwithstanding the foregoing, the Trustee shall retain all rights under this Indenture to be indemnified for expenses incurred related to such proceeding.

Section 6.02. Payments of Notes on Default; Suit Therefor. The Issuer covenants that in the case of an Event of Default pursuant to Section 6.01(a)(1) or 6.01(a)(2), upon demand of the Trustee, the Issuer will pay to the Trustee, for the benefit of the Holders of the Notes, (i) the whole amount that then shall be due and payable on all such Notes for principal or Interest, as

34

the case may be, with Interest upon the overdue principal and (to the extent that payment of such Interest is enforceable under applicable law) upon the overdue installments of accrued and unpaid Interest at the rate borne by the Notes from the required payment date and, (ii) in addition thereto, any amounts due the Trustee under this Indenture, including, but not limited to, Section 7.06.

36

one or more Holders of Notes shall have any right in any manner whatever by virtue of or by reference to any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder of Notes, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders of Notes (except as otherwise provided herein).

Section 6.06. Remedies Cumulative and Continuing. All powers and remedies given by this Article 6 to the Trustee or to the Noteholders 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 of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any default or Event of Default occurring and continuing as aforesaid shall impair any such right or power, or shall be construed to be a waiver of any such default or any acquiescence therein, and, subject to the provisions of Section 6.04, every power and remedy given by this Article 6 or by law to the Trustee or to the Noteholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Noteholders.

The Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding shall have the right to direct, in writing, 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; provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture, (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and (c) the Trustee need not take any

37

action which might involve it in personal liability or be unduly prejudicial to the Holders of Notes not joining therein, it being understood that (subject to Section 7.02) the Trustee shall have no duty to ascertain whether or not such actions or forbearance are unduly prejudicial to such Holders.

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or Event of Default or impair any right consequent thereon.

44

corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided 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. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case any Notes shall not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Notes, in either its own name or that of its predecessor Trustee, with the full force and effect which this Indenture provides for the certificate of authentication of the Trustee.

Section 7.11. Appointment of Authenticating Agent .

If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. In case at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating 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 such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Issuer. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a termination, or in case

45

at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Issuer and shall give notice of such appointment to all Holders of Notes by mailing or causing to be mailed such notice to the Holders of Notes as they appear on the Note Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent herein. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Issuer agrees to pay to each Authenticating Agent from time to time reasonable compensation including reimbursement of its reasonable expenses for its services under this Section.

Whenever the Issuer or the Trustee solicits the taking of any action by the Holders of the Notes, the Issuer or the Trustee may fix in advance of such solicitation a date as the record date for determining Holders entitled to take such action. Notwithstanding Trust Indenture Act Section 316(c), such record date shall be the record date

47

specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Noteholders generally in connection therewith and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other act may be given before or after such record date, but only the Noteholders of record at the Close of Business on such record date shall be deemed to be Noteholders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Noteholders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

The holding of Notes shall be proved by the registry of such Notes or by a certificate of the Note Registrar.

Section 8.03. Absolute Owners . The Issuer, the Trustee, any Paying Agent, any exchange agent and any Note Registrar may deem the Person in whose name such Note shall be registered upon the Note Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person other than the Issuer or any Note Registrar) for the purpose of receiving payment of or on account of the principal of (including the repurchase price upon repurchase pursuant to Article 3) and Interest on such Note, for exchange of such Note and for all other purposes; and neither the Issuer nor the Trustee nor any Paying Agent nor any exchange agent nor any Note Registrar shall be affected by any notice to the contrary.

Section 8.04. Issuer-Owned Notes Disregarded . In determining whether the Holders of the requisite aggregate principal amount of Notes have given any request, demand, authorization, direction, notice, consent or waiver under this Indenture or whether a quorum is present at a meeting of Noteholders, Notes which are owned by the Issuer or any other obligor upon the Notes or any Affiliate of the Issuer or any other obligor on the Notes, as such ownership shall be reflected on the Note Register, shall be disregarded and deemed not to be outstanding for the purpose of any such determination, except that for purposes of determining whether the Trustee shall be protected in relying upon any such request, demand, authorization, direction, notice, consent or waiver thereunder or whether a quorum is present at a meeting of holders of Notes, only Notes that the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 8.04 if the pledgee shall establish to the satisfaction of the Trustee the pledgee’s right to vote such Notes and that the pledgee is not the Issuer, any other obligor on the Notes or any Affiliate of the Issuer or any such other obligor. In the case of a dispute as to such right, any

48

decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of the Trustee, the Issuer shall furnish to the Trustee promptly an Officers’ Certificate listing and identifying all Notes, if any, known by the Issuer to be owned or held by or for the account of any of the above described Persons, and, subject to Section 7.12, the Trustee shall be entitled to accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the fact that all Notes not listed therein are outstanding for the purpose of any such determination.

Section 8.05. Revocation of Consents; Future Holders Bound . At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note which is shown by the evidence to be included in the Notes the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Note. Except as aforesaid, any such action taken by the Holder of any Note shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Note and of any Notes issued in exchange or substitution therefor, irrespective of whether any notation in regard thereto is made upon such Note or any Note issued in exchange or substitution therefor.

(b) (i) Prior to the Close of Business on the Business Day immediately preceding May 15, 2019, Notes may be surrendered for exchange on any date during any calendar quarter beginning after September 30, 2014 (and only during such calendar quarter) if the Closing Sale Price of the Common Stock was more than 130% of the then current Exchange Price for at least 20 Trading Days (whether or not consecutive) in the period of the 30 consecutive Trading Days ending on the last Trading Day of the previous calendar quarter.

then, in either case, the Issuer shall notify all Holders, the Trustee and the Exchange Agent (if other than the Trustee) at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or distribution by notice in writing, or if the Issuer does not have knowledge of such distribution at least 45 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution, within one Business Day of the date upon which the Issuer receives notice, or otherwise becomes aware, of such distribution. Once the Issuer has given such notice, a Holder may surrender all or any portion of its Notes for exchange any time until the earlier of (1) the Close of Business on the Business Day immediately preceding the Ex-Dividend Date for such issuance or distribution and (2) the Issuer’s announcement that such issuance or distribution will not take place.

(iv) If a transaction or event that constitutes a Fundamental Change or a Make-Whole Fundamental Change occurs prior to the Close of Business on the Business Day immediately preceding May 15, 2019, regardless of whether a Holder has the right to require the Issuer to repurchase the Notes pursuant to Section 3.02, or if the Company is a party to a consolidation, merger, binding share exchange, or transfer or lease of all or substantially all of its assets, in each case, pursuant to which the Common Stock would be converted into cash, securities or other assets (other than any merger or binding share exchange, in each case, solely for the purpose of changing the Company’s jurisdiction of organization that (x) does not constitute a Fundamental Change or a Make-Whole Fundamental Change and (y) results in a reclassification, conversion or exchange of outstanding shares of Common Stock solely into shares of common stock of the surviving entity), all or any portion of a Holder’s Notes may be surrendered for exchange at any time from or after the date that is 45 Scheduled Trading Days prior to the anticipated effective date of the transaction (or, if later, the Business Day after the Issuer gives notice of such transaction) until 35 Trading Days after the actual effective date of such transaction or, if such transaction also constitutes a Fundamental Change, until the related Fundamental Change Repurchase Date. The Issuer shall notify Holders, the Trustee and the Exchange Agent (if other than the Trustee) in writing (i) as promptly as practicable following the date the Issuer publicly announces such transaction but in no event less than 45 Scheduled Trading Days prior to the anticipated effective date of such transaction or (ii) if the Issuer does not have knowledge of such transaction at least 45 Scheduled Trading Days prior to the anticipated effective date of such transaction, within one Business Day of the date upon which the Company or the Issuer publicly announces such transaction, but in no event later than the actual effective date of such transaction.

(v) If the Company calls any or all of the Notes for redemption pursuant to Article 15 prior to the Close of Business on the Business Day immediately preceding May 15, 2019, then a Holder may surrender all or any portion of its Notes for exchange at any time prior to the Close of Business on the Scheduled Trading Day prior to the Redemption Date, even if the Notes are not otherwise exchangeable at such time. After that time, the right to convert such Notes as a result of such redemption shall expire, unless the Issuer defaults in the payment of the Redemption Price, in which case a Holder of Notes may convert its Notes until the Redemption Price has been paid or duly provided for.

58

Section 13.02. Exchange Procedures; Settlement Upon Exchange . (a) In order to exercise the exchange right with respect to any Notes in certificated form, a Holder must:

(i) complete and manually sign a notice of exchange in the form entitled “Form of Exchange Notice” attached to the reverse of such certificated Note (or a facsimile thereof) (an “ Exchange Notice ”);

(ii) deliver such Exchange Notice and the certificated Notes to be exchanged to the Exchange Agent at the office of the Exchange Agent;

(iii) to the extent any shares of Common Stock issuable upon exchange are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Exchange Agent;

(iv) if required pursuant to this Section 13.02(a), pay funds equal to Interest payable on the next Interest Payment Date to which such Holder is not entitled; and

(v) if required pursuant to Section 13.02(g), pay all transfer or similar taxes, if any.

In order to exercise the exchange right with respect to any interest in a Global Note, a Holder must:

(i) submit an Exchange Notice through the facilities of the Depositary and the Exchange Notice must comply with all applicable Depositary procedures;

(ii) if required pursuant to this Section 13.02(a), pay funds equal to Interest payable on the next Interest Payment Date to which such Holder is not entitled; and

(iii) if required pursuant to Section 13.02(g), pay all transfer or similar taxes, if any.

The date on which the Holder satisfies the foregoing requirements is the “ Exchange Date. ” The Notes shall be deemed to have been exchanged immediately prior to the Close of Business on the Exchange Date; provided, however , that the Person in whose name any shares of the Common Stock shall be issuable upon such exchange shall become the holder of record of such shares as of the Close of Business on the Exchange Date, in the case of Physical Settlement, or the last Trading Day of the relevant Observation Period, in the case of Combination Settlement.

Whether the Notes to be exchanged are held in book-entry or certificated form, the Exchange Notice will require the Holder to certify that it is a qualified institutional buyer within the meaning of Rule 144A under the Securities Act.

If a Holder exchanges any Notes after the Close of Business on the Record Date for an Interest payment but prior to the corresponding Interest Payment Date, the record Holder on such Record Date (if other than such Holder) shall receive on the corresponding Interest Payment Date the full amount of Interest accrued and unpaid on such Notes, notwithstanding such

59

Holder’s exchange of those Notes prior to the Interest Payment Date. However, except as provided in the next sentence, at the time such Holder surrenders its Notes for exchange after the Close of Business on a Record Date but prior to the Open of Business on the corresponding Interest Payment Date, such Holder must pay the Issuer an amount equal to the Interest that has accrued and shall be paid on the Notes being exchanged on the corresponding Interest Payment Date. However, such Holder is not required to make such payment:

(i) if such Holder exchanges its Notes following the Close of Business on the Record Date immediately preceding the Maturity Date;

(ii) if the Issuer has specified a Redemption Date that is after a Record Date and on or prior to the date the corresponding Interest is paid;

(iii) if such Holder exchanges its Notes in connection with a Fundamental Change and the Issuer has specified a Fundamental Change Repurchase Date that is after a Record Date and on or prior to the date the corresponding Interest is paid; or

(iv) to the extent of any overdue Interest, if overdue Interest exists at the time of exchange with respect to such Holder’s Notes.

For the avoidance of doubt, all Record Holders of Notes on the Record Date immediately preceding the Maturity Date, any Redemption Date and any Fundamental Change Repurchase Date described in (i), (ii) and (iii) above will receive the full Interest payment due on the Maturity Date or other applicable Interest Payment Date regardless of whether their Notes have been exchanged following such Record Date.

If a Holder has already delivered a Fundamental Change Repurchase Notice pursuant to Section 3.02 with respect to a Note, such Holder may not surrender that Note for exchange until such Holder has validly withdrawn the Fundamental Change Repurchase Notice in accordance with Section 3.04, except as to a portion of such Note that is not subject to such Fundamental Change Repurchase Notice.

Upon surrender of a Note for exchange by a Holder, such Holder shall deliver to the Issuer cash equal to the amount that the Issuer is required to deduct and withhold under applicable law in connection with such exchange; provided, however, that if the Holder does not deliver such cash, the Issuer may deduct and withhold from the consideration otherwise deliverable to such Holder the amount required to be deducted and withheld under applicable law.

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

(b) Subject to this Section 13.02 and Section 13.04, upon exchange of any Note, the Issuer may, at its election, pay or deliver, as the case may be, to the exchanging Holder, in respect of each $1,000 principal amount of Notes being exchanged solely cash (“ Cash

60

Settlement ”), solely shares of Common Stock (other than cash in lieu of any fractional shares) (“ Physical Settlement ”) or a combination of cash and shares of Common Stock (“ Combination Settlement ”), as set forth in this Section 13.02(b).

All exchanges occurring on or after May 15, 2019 and all exchanges for which the relevant Exchange Date occurs after the Issuer’s issuance of a Redemption Notice with respect to the Notes and prior to the related Redemption Date shall be settled using the same Settlement Method. Prior to May 15, 2019 and with respect to any exchanges for which the relevant Exchange Date occurs after the Issuer’s issuance of a Redemption Notice but prior to the related Redemption Date, the Issuer shall use the same Settlement Method for all exchanges occurring on the same Exchange Date, but the Issuer shall not have any obligation to use the same Settlement Method with respect to exchanges that occur on different Exchange Dates. If the Issuer elects a Settlement Method, the Issuer shall notify Holders so exchanging, the Trustee and the Exchange Agent (if other than the Trustee) of such Settlement Method, no later than the Close of Business on the second Scheduled Trading Day immediately following the related Exchange Date (or, in the case of any exchanges for which the relevant Exchange Date occurs (i) subject to the immediately following clause (ii), on or after the date of issuance of a Redemption Notice, in such Redemption Notice and (ii) on or after May 15, 2019, no later than the Close of Business on the 45th Scheduled Trading Day immediately prior to the Maturity Date). If the Issuer does not timely elect a Settlement Method, the Issuer shall no longer have the right to elect Cash Settlement or Physical Settlement, and the Issuer shall be deemed to have elected Combination Settlement in respect of its Exchange Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. If the Issuer elects Combination Settlement but does not timely notify exchanging Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, such Specified Dollar Amount will be deemed to be $1,000.

The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any exchange of Notes (the “ Settlement Amount ”) shall be computed as follows:

(i) if the Issuer elects to satisfy its Exchange Obligation in respect of such exchange by Physical Settlement, the Issuer shall deliver to exchanging Holders in respect of each $1,000 principal amount of Notes being exchanged a number of shares of Common Stock equal to the Exchange Rate in effect on the Exchange Date (and cash in lieu of any fractional share as described in Section 13.02(i));

(ii) if the Issuer elects to satisfy its Exchange Obligation in respect of such exchange by Cash Settlement, the Issuer shall pay to exchanging Holders in respect of each $1,000 principal amount of Notes being exchanged cash in an amount equal to the sum of the Daily Exchange Values for each of the 40 consecutive Trading Days in the relevant Observation Period; and

(iii) if the Issuer elects (or is deemed to have elected) to satisfy its Exchange Obligation in respect of such exchange by Combination Settlement, the Issuer shall pay or deliver, as the case may be, to exchanging Holders in respect of each $1,000 principal amount of Notes being exchanged, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 40 consecutive Trading Days in the relevant Observation Period (and cash in lieu of any fractional share as described in Section 13.02(i)).

61

(c) Except as set forth in Section 13.04, if Cash Settlement or Combination Settlement is applicable, the Issuer shall pay and/or deliver the consideration due upon exchange on the third Business Day immediately following the final Trading Day of the related Observation Period. If Physical Settlement is applicable, the Issuer shall deliver the consideration due upon exchange on the third Business Day immediately following the related Exchange Date; provided that, with respect to any Exchange Date with respect to which Physical Settlement applies occurring after May 15, 2019, settlement will occur on the Maturity Date.

(d) If more than one Note shall be surrendered for exchange at one time by the same Holder, the Exchange Obligation with respect to such Notes, if any, that shall be payable upon exchange 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.

(e) In case any certificated Note shall be surrendered for partial exchange, the Issuer shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the certificated Note so surrendered, without charge to such Holder, a new certificated Note or Notes in authorized denominations in an aggregate principal amount equal to the unexchanged portion of the surrendered certificated Note.

(f) Upon the exchange of an interest in a Global Note, the Trustee and the Depositary shall reduce the principal amount of such Global Note in their records.

(g) The issue of stock certificates on exchanges of Notes shall be made without charge to the exchanging Holder of Notes for any taxes or duties in respect of the issue thereof. The Issuer shall not, however, be required to pay any such tax or duty which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Notes exchanged, and the Issuer shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Issuer the amount of such tax or duty or shall have established to the satisfaction of the Issuer that such tax has been paid.

(h) Except as provided in Section 13.02(a), upon exchange, Holders shall not receive any separate cash payment of accrued and unpaid Interest on the Notes. Accrued and unpaid Interest to the Exchange Date shall be deemed to be paid in full with the payment or delivery, as the case may be, of the cash, Common Stock or a combination thereof, upon exchange, rather than cancelled, extinguished or forfeited. With respect to any exchange with Combination Settlement, accrued and unpaid Interest will be deemed to be paid first out of the cash paid upon such exchange.

(i) The Issuer shall not deliver fractional shares of Common Stock upon exchange of the Notes. If any fractional shares of Common Stock would be issuable upon the exchange of any Note or Notes, the Issuer shall instead pay cash in lieu of fractional shares based on the Closing Sale Price of the Common Stock on the relevant Exchange Date, in the case of Physical Settlement, or on the final Trading Day of the relevant Observation Period, in the case of Combination Settlement.

62

(j) Except as may be set forth in Section 13.03, the Issuer shall not make any payment or other adjustment for dividends on any Common Stock issued upon exchange of the Notes.

(k) The Issuer shall inform the Trustee upon its request if the Notes have become exchangeable under Section 13.01(b).

Section 13.03. Adjustment of Exchange Rate . The Exchange Rate shall be adjusted from time to time as follows:

(a) If the Company issues Common Stock as a dividend or distribution on Common Stock, or if the Company effects a share split or share combination, the Exchange Rate will be adjusted based on the following formula:

where

If any dividend or distribution described in this paragraph (a) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared or such subdivision or combination had not been announced.

(b) If the Company distributes to all, or substantially all, holders of Common Stock any rights, warrants or options entitling them for a period of not more than 45 days after the announcement date of such issuance to subscribe for or purchase Common Stock at an exercise

63

price per share of Common Stock less than the average of the Closing Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the time of announcement of such issuance, the Exchange Rate will be adjusted based on the following formula:

where

Any increase made under this Section 13.03(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-Dvidend 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 Exchange Rate shall be readjusted to the Exchange 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 Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such Ex-Dividend Date for such issuance had not occurred.

For purposes of this Section 13.03(b) and for the purpose of Section 13.01(b)(iii)(A), in determining whether any rights, warrants or options entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Closing 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 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 the Issuer or 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 or a committee thereof.

64

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other assets or property of the Company to all, or substantially all, holders of Common Stock, excluding:

(A) dividends, distributions, rights, warrants or options referred to in clause (a) or (b) of this Section 13.03;

(B) dividends or distributions paid exclusively in cash;

(C) Spin-Offs described below in this clause (c); and

(D) Any distributions of Reference Property pursuant to a transaction described below under Section 13.05, then the Exchange Rate will be adjusted based on the following formula:

where

Any increase made under the portion of this Section 11.03(c) above will become effective immediately after the Open of Business on the Ex-Dividend Date for such distribution. If such distribution is not so paid or made, the Exchange Rate shall be decreased to be the Exchange Rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” with respect to any distribution of shares of Capital Stock, evidences of indebtedness or other assets or property of the Company is equal to or greater than “SP ₀ ” with respect to such distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Notes shall have the right to receive on the date such shares of Capital Stock, evidences of indebtedness or other assets or property of the Company are distributed to holders of Common Stock, for each Note, the amount of shares of Capital Stock, evidences of indebtedness or other assets or property of the Company such holder of Notes would have received had such holder of Notes owned a number of shares of Common Stock

65

equal to a fraction (x) the numerator of which is the product of the Exchange Rate in effect on the Ex-Dividend Date for such distribution, and the aggregate principal amount of Notes held by such Holder and (y) the denominator of which is $1,000.

With respect to an adjustment to the Exchange Rate made pursuant to this clause (c), where there has been a payment of a dividend or other distribution of Common Stock or 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 that are or, when issued, will be, listed or admitted for trading on a U.S. national or regional securities exchange (a “ Spin-Off ”), the Exchange Rate will be adjusted based on the following formula:

where

An adjustment to the Exchange Rate made pursuant to the immediately preceding paragraph will become effective immediately after the end of the Valuation Period; provided that in respect of any exchange within the Valuation Period, references within this clause (c) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the Exchange Date in determining the applicable Exchange Rate.

If any dividend or distribution described in this clause (c) is declared but not paid or made, the new Exchange Rate shall be readjusted to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

For purposes of this Section 13.03(c) (and subject in all respect to Section 13.03(f)), rights, options or warrants distributed by the Company to all holders of the Common Stock entitling them to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or

66

warrants, until the occurrence of a specified event or events (“ Trigger Event ”): (i) are deemed to be transferred with such shares of the Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 13.03(c) (and no adjustment to the Exchange Rate under this Section 13.03(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate shall be made under this Section 13.03(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 13.03(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Exchange Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Exchange Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of 13.03(a), Section 13.03(b) and this Section 14.03(c), if any dividend or distribution to which this Section 13.03(c) is applicable also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 13.03(a) is applicable (the “ Clause A Distribution ”); or

(B) a dividend or distribution of rights, options or warrants to which Section 13.03(b) is applicable (the “ Clause B Distribution ”),

then (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 13.03(c) is applicable (the “ Clause C Distribution ”) and any Exchange Rate adjustment required by this Section 13.03(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Exchange Rate adjustment required by Section 13.03(a) and Section 13.03(b) with respect thereto shall then be made, except that, if determined by the Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the

67

Clause B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C Distribution and (II) any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Open of Business on such Ex-Dividend Date, or effective date” within the meaning of Section 13.03(a) or “outstanding immediately prior to the Open of Business on the Ex-Dividend Date” within the meaning of Section 13.03(b).

(d) If the Company makes any cash dividend or distribution to all, or substantially all, holders of outstanding Common Stock, other than cash dividends in any fiscal quarter that do not exceed in aggregate $0.085 per share (such threshold, subject to adjustment as provided below, the “ Dividend Threshold ”) the Exchange Rate will be adjusted based on the following formula:

where

The Dividend Threshold is subject to adjustment in a manner inversely proportional to adjustments to the Exchange Rate made pursuant to the provisions described in this Section 11.03; provided that no adjustment will be made to the Dividend Threshold for any adjustment to the Exchange Rate under this clause (d).

If any dividend or distribution described in this clause (d) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared, effective as of the date the Board of Directors or committee thereof determines not to make or pay such dividend or distribution. Notwithstanding the foregoing, if “C” with respect to any such cash dividend or distribution is equal to or greater than “SP ₀ ” with respect to any such cash dividend or distribution, then in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of Notes shall have the right to receive on the date such cash is distributed to holders of Common Stock, for each Note, the amount of cash such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Exchange Rate in effect on the Ex-Dividend Date for such dividend or distribution.

68

If any dividend or distribution described in this paragraph (d) is declared but not so paid or made, the new Exchange Rate shall be readjusted to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer that is subject to the then applicable tender offer rules under the Exchange Act 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 Closing Sale Price of a share of Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “ Expiration Time ”), the Exchange Rate will be adjusted based on the following formula:

where

The adjustment to the exchange rate under the preceding paragraph shall occur on the 10th Trading Day from, and including, the Trading Day next succeeding the date such tender or exchange offer expires; provided that in respect of any exchange within 10 Trading Days immediately following, and including, the expiration date of any tender or exchange offer, references with respect to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the expiration date of such tender or exchange offer and the Exchange Date in determining the applicable Exchange Rate.

69

If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender offer or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Exchange Rate shall be readjusted to be the Exchange Rate that would be in effect if such tender offer or exchange offer had not been made.

(f) If the Company has in effect a rights plan while any Notes remain outstanding, Holders of Notes will receive, upon an exchange of Notes, in addition to Common Stock, if any, rights under the Company’s stockholder rights agreement unless, prior to exchange, the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock. If the rights provided for in the rights plan adopted by the Company have separated from the Common Stock and have not expired, terminated or been redeemed, in each case, in accordance with the provisions of the applicable stockholder rights agreement so that Holders of Notes would not be entitled to receive any rights in respect of any shares of Common Stock delivered upon an exchange of Notes, the Exchange Rate will be adjusted at the time of separation as if the Company had distributed, to all holders of Common Stock, Capital Stock, evidences of indebtedness or other assets or property pursuant to clause (c) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights.

(g) If, in the case of any exchange of a Note, on any Trading Day during the Observation Period for such Note, shares of Common Stock are deliverable as part of the Daily Settlement Amount for such Trading Day, and

(i) the Ex-Dividend Date for any issuance, dividend or distribution, the effective date for any share split or combination or the expiration date for any tender or exchange offer by the Company that, in each case, would require an adjustment to the Exchange Rate under clauses (a) through (e) above occurs prior to the Issuer’s delivery of such shares of Common Stock to the exchanging Holder;

(ii) the applicable Exchange Rate for such Trading Day will not reflect such adjustment; and

(iii) the shares of Common Stock that the Issuer will deliver to the exchanging Holder with respect of such Trading Day are not entitled to participate in the relevant event (because they were not held on the related Ex-Dividend Date, effective date, expiration date or otherwise),

then the Issuer will adjust the number of shares of Common Stock that it delivers to such Holder as part of the Daily Settlement Amount for such Trading Day in a manner that appropriately reflects the relevant distribution, transaction or event.

Notwithstanding the foregoing, if an Exchange Rate adjustment becomes effective on any Ex-Dividend Date as described in Section 13.03(a) through 13.03(e) above, and a Holder of Notes that has exchanged its Notes on or after such Ex-Dividend Date and on or prior to the

70

related record date would be treated as the record holder of Common Stock as of the related Exchange Date as described under Section 13.02, based on an adjusted Exchange Rate for such Ex-Dividend Date, then, notwithstanding the foregoing Exchange Rate adjustment provisions of Section 13.03(a) through (e), the Exchange Rate adjustment relating to such Ex-Dividend Date will not be made for such exchanging Holder. Instead, such Holder will be treated as if such Holder were, as of such record date, the record owner of the Common Stock issuable upon such exchange on an unadjusted basis and will participate in the related dividend, distribution or other event giving rise to such adjustment.

(h) The Issuer shall not make any adjustment to the Exchange Rate if Holders of the Notes are permitted to participate in the transactions described in this Section 13.03 on a basis equivalent to that which would apply if the Notes were exchanged entirely for Common Stock at the then-applicable Exchange Rate. If, however, the application of the foregoing formulas would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate shall be made (other than as a result of an adjustment pursuant to Section 13.03(a)).

Notwithstanding anything to the contrary contained herein, the applicable Exchange Rate shall not be adjusted for:

(i) the issuance of any Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Issuer or those of the Company and the investment of additional optional amounts in the Common Stock under any plan;

(ii) the issuance of any Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director, trustee or consultant benefit plan, employee agreement or arrangement or program of the Company or any of its subsidiaries;

(iii) the issuance of any Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security outstanding as of the date the Notes were first issued;

(iv) a change in the par value of the Common Stock;

(v) accumulated and unpaid dividends or distributions;

(vi) the issuance of Units by the Issuer and the issuance of the Common Stock or the payment of cash upon redemption thereof; and

(vii) the repurchase of any shares of Common Srock pursuant to an open-marked share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the kind described under Section 11.03(e).

Adjustments to the applicable Exchange Rate shall be calculated to the nearest 1/10,000th of a share. The Issuer shall not adjust the Exchange Rate pursuant to the provisions of this Section 11.03 unless the adjustment would result in a change of at least 1% of the then effective Exchange Rate. However, the Issuer shall carry forward any adjustment that it would otherwise

71

have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) in connection with any subsequent adjustment to the Exchange Rate of at least 1% and (ii) on each Trading Day of any Observation Period related to the exchange of the Notes.

Notwithstanding anything to the contrary herein, certain listing standards of The New York Stock Exchange may limit the amount by which the Issuer may increase the Exchange Rate pursuant to the events described in clauses (a) through (e) in this Section 13.03 and as described in Section 13.04. These standards generally require the Company to obtain the approval of its stockholders before entering into certain transactions that potentially result in the issuance of 20% or more of Common Stock outstanding at the time the Notes are issued unless the Company obtains stockholder approval of issuances in excess of such limitations. Accordingly, in the event of an increase in the Exchange Rate above that which would result in the Notes, in the aggregate, becoming exchangeable into shares in excess of such limitations, the Company will, at its option, either obtain stockholder approval of such issuances or pay cash in lieu of delivering any shares otherwise deliverable upon exchange in excess of such limitations based on the volume-weighted average price of Common stock for each Trading Day of the relevant Observation Period in respect of which, in lieu of delivering common shares, the Issuer delivers cash pursuant to this paragraph, in the case of Combination Settlement, or based on the Closing Sale Price of Common Stock on an Exchange Date with respect to Physical Settlement.

The Issuer from time to time may increase the Exchange Rate by any amount for a period of at least 20 Business Days if the Board of Directors or a committee thereof determines that such increase would be in the Company’s best interest. In addition, the Issuer may also (but is not required to) increase the Exchange Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

Except as set forth above in this Article 13, the Exchange Rate shall not be adjusted.

Whenever the Exchange Rate is adjusted as herein provided, the Company or the Issuer shall as promptly as reasonably practicable file with the Trustee and any Exchange Agent other than the Trustee an Officer’s’ Certificate setting forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company or the Issuer shall prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Exchange Rate to the Holders of the Notes within 20 Business Days of the Effective Date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

For purposes of this Section 13.03, “effective date” means the the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable.

(i) Whenever any provision of this Indenture requires the Issuer to calculate the Closing Sale Prices, the volume-weighted average price, the Daily Exchange Values or the Daily Settlement Amounts over, or based on, a span of multiple calendar days (including an

72

Observation Period, Valuation Period or Averaging Period), the Issuer shall make appropriate adjustments to each (to the extent no corresponding adjustment is otherwise made pursuant to the provisions of this Section 13.03) to account for any adjustment to the Exchange Rate that becomes effective, or any event requiring an adjustment to the Exchange Rate where the Ex-Dividend Date of the event occurs, at any time during the period when the Closing Sale Prices, the volume-weighted average prices, the Daily Exchange Values or the Daily Settlement Amounts are to be calculated.

Section 13.04. Exchange Rate Adjustment After Make-Whole Fundamental Change. (a) Subject to the provisions hereof, if a Noteholder elects to exchange its Notes in connection with a Make-Whole Fundamental Change, the Issuer will increase the applicable Exchange Rate for the Notes so surrendered for exchange by a number of additional shares of Common Stock (the “ Additional Shares ”) as specified below; provided that the Additional Shares will only be payable as set forth below. An exchange of Notes will be deemed for these purposes to be “in connection with” such a Make-Whole Fundamental Change if the Exchange Date occurs during the period from the effective date of such Make-Whole Fundamental Change until the corresponding Fundamental Change Repurchase Date or, if such Make-Whole Fundamental Change is not also a Fundamental Change, the 35th Business Day immediately following the effective date for such Make-Whole Fundament Change.

Upon surrender of Notes for exchange in connection with a Make-Whole Fundamental Change, the Issuer shall, at its option, satisfy its Exchange Obligation by Physical Settlement, Cash Settlement or Combination Settlement, as described under Section 13.02(b). However, if the consideration received by holders of the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is composed entirely of cash, for any exchange of Notes following the Effective Date of such Make-Whole Fundamental Change, the Settlement Amount will be calculated based solely on the Stock Price for the transaction and will be deemed to be an amount of cash per $1,000 principal amount of exchanged Notes equal to the Exchange Rate (including any adjustment as described in this Section 13.04), multiplied by such Stock Price. In such event, the Issuer shall satisfy its Exchange Obligation by paying cash to exchanging Holders on the third Business Day immediately following the Exchange Date.

(b) The number of Additional Shares will be determined by reference to the table in paragraph (e) below and is based on the date on which the Make-Whole Fundamental Change transaction becomes effective (the “ Effective Date ”) and the price (the “ Stock Price ”) paid per share of Common Stock in such transaction. If the holders of Common Stock receive only cash in the relevant Make-Whole Fundamental Change transaction, the Stock Price will equal the cash amount paid per share of Common Stock. In all other cases, the Stock Price will equal the average of the Closing Sale Prices of the Common Stock on the 10 consecutive Trading Days up to but excluding the Effective Date.

(c) The Stock Prices set forth in the first row of the table below shall be adjusted as of any date on which the Exchange Rate of the Notes is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and (ii) the denominator of which is the Exchange Rate as so adjusted.

73

(d) The number of Additional Shares will be adjusted in the same manner and for the same events as the Exchange Rate is adjusted pursuant to Section 13.03.

(e) The following table sets forth the number of Additional Shares by which the Exchange Rate will be increased per $1,000 principal amount of Notes for each Stock Price and Effective Date set forth below:

(f) If the exact Stock Price and Effective Date are not set forth on the table above, then:

(i) if the Stock Price is between two Stock Prices in the table or the Effective Date is between two dates in the table, the Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the two dates, as applicable, based on a 365- or 366-day year, as applicable;

(ii) if the Stock Price is in excess of $70.00 per share of Common Stock (the “ Adjustment Cap ”) (subject to adjustment) no Additional Shares will be added to the applicable Exchange Rate; and

(iii) if the Stock Price is less than $15.88 per share of Common Stock (the “ Adjustment Floor ”) (subject to adjustment) no Additional Shares will be added to the applicable Exchange Rate.

The Adjustment Cap and Adjustment Floor shall be adjusted as of any date on which the Exchange Rate of the Notes is adjusted pursuant to Section 13.03. The adjusted Adjustment Cap or Adjustment Floor, as the case may be, shall equal the Adjustment Cap or Adjustment Floor, as the case may be, applicable immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exchange Rate immediately prior to the adjustment giving rise to the adjustment and (ii) the denominator of which is the Exchange Rate as so adjusted.

(g) Notwithstanding anything in this Section 13.04 to the contrary, in no event will the total number of shares of Common Stock issuable upon exchange of the Notes exceed 62.9722 per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Exchange Rate pursuant to Section 13.03.

74

Section 13.05. Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale . (a) If any of the following events occur:

(i) any recapitalization, reclassification or change of shares of Common Stock issuable upon exchange of the Notes (other than a change as a result of a subdivision or combination or change in par value);

(ii) any consolidation, merger or combination involving the Company with another Person as a result of which holders of Common Stock shall be entitled to receive cash, securities or other property or assets (including cash or any combination of the foregoing) with respect to or in exchange for such Common Stock; or

(iii) any sale, lease or other transfer to a third party of all or substantially all of the consolidated assets of the Company and its Subsidiaries to any other Person as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination of the foregoing) with respect to or in exchange for such Common Stock,

(any such event, a “ Merger Event ”) then, at the effective time of the Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental indenture) providing that the Notes shall be exchangeable for the kind and amount of shares of stock, securities or other property or assets (including cash or any combination of the foregoing) receivable upon such recapitalization, reclassification, change, consolidation, merger, combination, sale or conveyance (the “ Reference Property ”) by a holder of a number of shares of Common Stock issuable upon exchange for such Notes (assuming, for such purposes, a sufficient number of authorized shares of Common Stock available to exchange all such Notes) immediately prior to such Merger Event. However, at and after the effective time of the Merger Event, (a) the Issuer shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, as set forth in Section 13.02 and (B)(1) any amount payable in cash upon exchange of the Notes as set forth in Section 13.02 will continue to be payable in cash, (2) any shares of Common Stock that the Issuer would have been required to deliver upon exchange of the Notes as set forth in Section 13.02 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 transaction and (3) VWAP will be calculated based on the value of the amount and kind of Reference Property that a holder of one share of Common Stock would have received in such transaction. If the Merger Event causes Common Stock to be exchanged for the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property for which the Notes will be exchangeable shall be deemed to be (x) the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such election or (y) if no holders of Common Stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of Common Stock.

75

In connection with any transaction described in this Section 13.05 the Issuer shall also adjust the Dividend Threshold based on the ratio of the value of the shares of common stock, if any, comprising the Reference Property to the value of any non-stock consideration comprising the Reference Property. If the Reference Property is composed solely of non-stock consideration, the Dividend Threshold will be zero.

Such supplemental indenture providing that the Notes will be exchangeable into Reference Property will also provide for antidilution and other adjustments that are as nearly equivalent as possible to the adjustments described under this Article 13. If the Reference Property in respect of any such transaction includes shares of stock, securities or other property or assets of a company other than the Company or the successor or purchasing corporation, as the case may be, in such transaction, such other company will also execute such supplemental indenture, and such supplemental indenture will contain such additional provisions to protect the interests of the Holders, including the right of Holders to requirethe Issuer to repurchase their Notes upon a Fundamental Change as described under Section 3.02, as the Board of Directors or committee thereof reasonably considers necessary by reason of the foregoing.

The Issuer shall cause notice of the execution of such supplemental indenture to be mailed to each Holder, at the address of such Holder as it appears on the Note Register maintained by the Note Registrar, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 13.05 shall similarly apply to successive recapitalizations, reclassifications, changes, consolidations, mergers, combinations, sales and conveyances.

(b) Neither the Company nor the Issuer shall become a party to any such transaction unless its terms are consistent with this Section 13.05.

Section 13.06. Ownership Limit and Withholding .

(a) Notwithstanding any other provision of the Notes or this Indenture, no Holder of Notes will be entitled to receive Common Stock following exchange of such Notes to the extent that receipt of such Common Stock would cause such Holder to exceed the ownership limits contained in the Company’s Charter. If any delivery of shares of Common Stock owed to a Holder upon exchange of Notes is not made, in whole or in part, as a result of the limitations described in this Section 13.06 (a), the Issuer’s obligation to make such delivery shall not be extinguished and the Issuer shall deliver such shares as promptly as practicable after any such exchanging Holder gives notice to the Issuer that such delivery would not result in it being the beneficial or constructive owner of more than 9.8% (in value or in number of shares, whichever is more restrictive) of the shares of Common Stock outstanding at such time.

(b) At the Maturity Date, upon earlier repurchase of the Notes or at any time a payment is made with respect to the Notes, and as otherwise required by law, the Issuer may deduct and withhold from such amount otherwise deliverable to the Holder the amount required to be deducted and withheld under applicable law, and such amount shall be deemed paid to such Holder for all purposes of this Indenture.

Section 13.07. Calculations in Respect of Notes . Except as otherwise specifically stated herein or in the Notes, all calculations to be made in respect of the Notes shall be the obligation of the Issuer. These calculations include, but are not limited to, determinations of the Closing

76

Sale Price or the volume-weighted average price of the Common Stock, the Daily Settlement Amounts, the Daily Exchange Values, accrued Interest payable on the Notes, the Exchange Rate and the Exchange Price. All calculations made by the Issuer or its agent as contemplated pursuant to the terms hereof and of the Notes shall be made in good faith and be final and binding on the Notes and the Holders of the Notes absent manifest error. The Issuer shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Issuer without independent verification. The Trustee, at the expense of the Issuer, shall forward calculations made by the Issuer to any Holder of Notes upon written request. None of the Trustee, the Note Registrar, the Paying Agent, the Exchange Agent and the Bid Solicitation Agent (if other than the Issuer) shall have any responsibility to determine the Trading Price of the Notes or the Closing Sale Price or whether the conditions to exchange specified in Article 13 have been satisfied.

Section 13.08. Designation to an Institution in Lieu of Exchange . When a Holder surrenders its Notes for exchange, the Issuer may, at its election (an “ Exchange Election ”), direct the Exchange Agent to surrender, on or prior to the second Trading Day following the Exchange Date, such Notes to a financial institution designated by the Issuer in lieu of exchange. In order to accept any Notes surrendered for exchange, the designated financial institution must agree to timely deliver, in exchange for such Notes, the shares of Common Stock, cash or combination thereof due upon exchange as described above under Section 13.02. If the Issuer makes an Exchange Election, it will, by the Close of Business on the second Trading Day following the relevant Exchange Date, notify the Holder surrendering its Notes for exchange that it has made the Exchange Election, and it will notify the designated financial institution of the Settlement Method it has elected with respect to such exchange and the relevant deadline for payment and/or delivery of shares of Common Stock, cash or a combination thereof due upon exchange.

Any Notes exchanged by the designated institution will remain outstanding. If the designated institution agrees to accept any Notes for exchange but does not timely pay or deliver the aggregate cash, shares of Common Stock or a combination of cash and shares Common Stock, as the case may be, due upon exchange or if such designated financial institution does not accept the Notes for exchange, the Issuer will pay or deliver, as the case may be, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, to the exchanging Holder at the time and in the manner required herein as if it had not made an Exchange Election.

The Issuer’s designation of an institution to which the Notes may be designated does not require the institution to accept any Notes (unless the financial institution has separately made an agreement with the Issuer). The Issuer may, but will not be obligated to, enter into a separate agreement with any designated financial institution that would compensate it for any such transaction.

REDEMPTION TO PRESERVE REIT STATUS

Section 15.01. Redemption to Preserve REIT Qualification .

No sinking fund shall be required for the Notes. The Notes shall not be redeemable by the Issuer prior to the Maturity Date except to the extent necessary to preserve the Company’s qualification as a REIT for United States federal incomes tax purposes. If the Issuer determines that it is necessary to redeem the Notes prior to the Maturity Date to preserve the Company’s qualification as a REIT, the Issuer may redeem (a “ Redemption ”) for cash all or part of the Notes as necessary to preserve the Company’s REIT qualification, at the Redemption Price.

80

Section 15.02. Notice of Redemption; Selection of Notes .

(a) In case the Issuer exercises its right to redeem all or, as the case may be, any part of the Notes pursuant to Section 15.01, it shall fix a date for redemption (each, a “ Redemption Date ”) and it or, at its written request received by the Trustee not less than 50 Scheduled Trading Days prior to the Redemption Date (or such shorter period of time as may be acceptable to the Trustee), the Trustee, in the name of and at the expense of the Issuer, shall send a notice of such Redemption (a “ Redemption Notice ”) not less than 45 Scheduled Trading Days nor more than 75 calendar days prior to the Redemption Date to each Holder of Notes so to be redeemed; provided, however, that, if the Issuer shall give such notice, it shall also give written notice of the Redemption Date to the Trustee. The Redemption Date must be a Business Day.

(b) The Redemption Notice, if sent in the manner provided in herein, shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such Redemption Notice by mail, electronic delivery or otherwise or any defect in the Redemption Notice to the Holder of any Note designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note.

(c) Each Redemption Notice shall specify:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) that on the Redemption Date, the Redemption Price will become due and payable upon each Note to be redeemed, and that Interest thereon, if any, shall cease to accrue on and after the Redemption Date (except as provided in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date but on or prior to the immediately succeeding Interest Payment Date);

(iv) the place or places where such Notes are to be surrendered for payment of the Redemption Price;

(v) that Holders may surrender their Notes for exchange at any time prior to the Close of Business on the Scheduled Trading Day immediately preceding the Redemption Date;

(vi) the procedures a converting Holder must follow to exchange its Notes and the Settlement Method and Specified Dollar Amount, if applicable;

(vii) the Exchange Rate and, if applicable, the number of Additional Shares added to the Exchange Rate in accordance with Section 13.04;

(viii) the CUSIP or other similar numbers, if any, assigned to such Notes; and

(ix) in case any Note is to be redeemed in part only, the portion of the principal amount thereof to be redeemed and that on and after the Redemption Date, upon surrender of such Note, a new Note in principal amount equal to the unredeemed portion thereof shall be issued.

81

A Redemption Notice shall be irrevocable.

(d) If fewer than all of the outstanding Notes are to be redeemed, the Trustee shall select the Notes or portions thereof to be redeemed (in principal amounts of $1,000 or integral multiples thereof) by lot, on a pro rata basis or by another method the Trustee considers to be fair and appropriate and in each case subject to requirements of applicable law and of the applicable Depositary. If any Note selected for redemption is submitted for exchange after such selection, the portion of the Note submitted for exchange shall be deemed (so far as may be possible) to be the portion selected for redemption.

Section 15.03. Payment of Notes Called for Redemption .

(a) If any Redemption Notice has been given in respect of the Notes in accordance with Section 15.02, the Notes shall become due and payable on the Redemption Date at the place or places stated in the Redemption Notice and at the applicable Redemption Price, except as provided in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date but on or prior to the immediately succeeding Interest Payment Date. On presentation and surrender of the Notes at the place or places stated in the Redemption Notice, the Notes shall be paid and redeemed by the Company at the applicable Redemption Price.

Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made promptly after the later of:

(i) the Redemption Date for such Notes; and

(ii) the time of presentation of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by this Section 15.03.

The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

Section 15.04. Effect of Redemption . If by 11:00 a.m. New York City time, on the Redemption Date for a Redemption, the Trustee (or other Paying Agent appointed by the Issuer) holds money sufficient to make payment on all the Notes or portions thereof that are to be redeemed on such Redemption Date, then, with respect to the Notes that have been called for such Redemption, (i) such Notes will cease to be outstanding, (ii) Interest will cease to accrue on such Notes (whether or not book-entry transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying Agent), except to the extent set forth in the definition of Redemption Price with respect to a Redemption Date that falls after a Record Date but on or prior to the immediately succeeding Interest Payment Date, and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Redemption Price).

82

Section 15.05. Restrictions on Redemption . The Issuer may not redeem any Notes on any date if the principal amount of the Notes has been accelerated in accordance with the terms of this Indenture, and such acceleration has not been rescinded, on or prior to the Redemption Date (except in the case of an acceleration resulting from a Default by the Issuer in the payment of the Redemption Price with respect to such Notes).
