ARTICLE 2

Issue, Description, Execution, Registration and Exchange of Notes

Section 2.01. Designation and Amount. The Notes shall be designated as the “3.50% Convertible Senior Notes due 2018.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is initially limited to $230,000,000, subject to Section 2.10 and except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 2.05, Section 2.06, Section 2.07, Section 9.04, Section 13.03(e) and Section 16.05.

Section 2.02. Form of Notes. The Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the respective forms set forth in Exhibit A, which are incorporated in and made a part of this Indenture.

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or as may be required by the Custodian or the Depositary, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

The Global Note shall represent such principal amount of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of Outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of Outstanding Notes represented thereby may from time to time be increased or reduced to reflect repurchases, conversions, transfers, exchanges or issuances of additional Notes permitted hereby. Any endorsement of the Global Note to reflect the amount of any increase or decrease in the amount of Outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in such manner and upon written instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including any Fundamental Change Repurchase Price, if applicable) of, and accrued and unpaid interest, if any, on, the Global Note shall be made to the Holder of such Note on the date of payment, unless a record date or other means of determining Holders eligible to receive payment is provided for herein.

The terms and provisions contained in the Form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

Section 2.03. Date and Denomination of Notes; Payments of Interest. The Notes shall be issuable in registered form without coupons in denominations of $2,000 principal amount and greater integral multiples of $1,000. 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 comprised of twelve 30-day months.

The Person in whose name any Note (or its Predecessor Note) is registered on the Note Register at the close of business on any Regular Record Date with respect to any Interest Payment Date shall be entitled to receive the interest payable on such Interest Payment Date. Interest shall be payable at the office of the Paying Agent, which shall initially be the Corporate Trust Office of the Trustee as the Company’s Paying Agent and Note Registrar. The Company shall pay interest on any Physical Notes (i) to the Person entitled thereto having an aggregate principal amount of $2,000,000 or less, by check mailed to such Person at the address set forth in the Note Register and (ii) to the Person entitled thereto having an aggregate principal amount of more than $2,000,000, either by check mailed to such Person or, upon application by such Person to the Note Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to such Person’s account within the United States, which application and wire transfer instructions shall remain in effect until such Person notifies, in writing, the Note Registrar to the contrary.

Any Defaulted Interest shall forthwith cease to be payable to the Holder of such Note on the relevant Regular Record Date by virtue of its having been such Holder, and such Defaulted Interest shall be paid by the Company, at its election in each case, as provided in clause (1) or (2) below:

(1) The Company 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 Company 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 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted 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 Company shall fix a special record date for the payment of such Defaulted Interest which shall be not more than fifteen days and not less than ten days prior to the date of the proposed payment, and not less than ten days after the receipt by the Trustee of the notice of the proposed payment. The Company shall promptly notify the Trustee in writing of such special record date and the Trustee, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be sent or mailed, first-class postage prepaid, to each Holder at its address as it appears in the Note Register, not less than ten days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (2) of this Section 2.03.

(2) The Company 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 written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.04. Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of any Officer.

At any time and from time to time after the date of the execution and delivery of this Indenture, the Company may, in accordance with the terms of this Indenture, deliver additional Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder.

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 a Responsible Officer of the Trustee (or an authorized officer of an authenticating agent appointed by the Trustee), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate of authentication executed by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

All Notes shall be dated that date of their authentication.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, 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 of the Company; and any Note may be signed on behalf of the Company by such Person as, at the actual date of the execution of such Note, shall be an Officer of the Company, although at the date of the execution of this Indenture any such person was not such an Officer.

The Trustee shall have the right to decline to authenticate and deliver any Notes under this Indenture if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith shall determine that such action would expose the Trustee to personal liability to existing Holders.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company being herein sometimes collectively referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company 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 converted into written form within a reasonable period of time. The Trustee is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint a new Note Registrar without prior notice to Holders. The Company may appoint one or more co-registrars.

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 Company 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.

Upon the registration of transfer, exchange or replacement of Notes not bearing or deemed not to bear the Restrictive Legend, the Note Registrar shall deliver Notes that do not bear the Restrictive Legend. Upon the registration of transfer, exchange or replacement of Notes bearing the Restrictive Legend, the Note Registrar shall deliver only Notes that bear the Restrictive Legend unless there is delivered to the Note Registrar an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither the Restrictive Legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.05. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

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

No service charge shall be charged by the Company, the Trustee or the Notes Registrar to the Holder for any exchange or registration of transfer of Notes, but the Holder may be required by the Company, the Trustee, the Notes Registrar or otherwise to pay a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange or registration of transfer of Notes being different from the name of the Holder of the old Notes presented or surrendered for such exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to exchange or register a transfer of any Notes surrendered for conversion or repurchase except for any portion of that Note that is not being repurchased or converted, as the case may be.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. For greater certainty, all Notes issued upon any registration of transfer or exchange of Notes shall be issued as evidence of the same continuing indebtedness of the Company under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the exchanged Notes by virtue of the registration of a transfer or exchange.

(b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law or except as provided in Section 2.05(c), all Notes shall be represented by one or more Notes in global form (each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary. The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor. Beneficial interests in the Global Note shall be held only in minimum denominations of $2,000 and greater integral multiples of $1,000. Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of any Holder.

(c) Every Note that bears or is required under this Section 2.05(c) to bear the Restrictive Legend (together with any Common Stock issued upon conversion of the Notes and required to bear a similar legend, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including the restrictions set forth in the Restrictive Legend), 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” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the Issue Date of a Note (including, if applicable, through exercise by the Initial Purchasers of their option to purchase additional Notes pursuant to the Purchase Agreement) and (2) such later date, if any, as may be required by applicable laws, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, and all shares of Common Stock, if any, issued upon conversion thereof, if applicable) shall bear a legend in substantially the following form (unless such Note or shares of Common Stock, if any, have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that continues to be effective at the time of such transfer, pursuant to the exemption from registration provided by Rule 144 or any similar provision then

in force under the Securities Act, or unless otherwise agreed by the Company in writing, with written notice thereof to the Trustee):

THE SECURITY (OR ITS PREDECESSOR) EVIDENCED HEREBY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER SECTION 5 OF THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THE SECURITY EVIDENCED HEREBY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY, MAY BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1)(a) INSIDE THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A UNDER THE SECURITIES ACT, (b) OUTSIDE THE UNITED STATES TO A NON-U.S. PERSON IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (c) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF APPLICABLE) OR (d) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT (AND BASED UPON AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY IF THE COMPANY SO REQUESTS), (2) TO THE COMPANY OR (3) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT AND, IN EACH CASE, IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THE SECURITY EVIDENCED HEREBY OF THE RESALE RESTRICTIONS SET FORTH IN CLAUSE (A) ABOVE. NO REPRESENTATION CAN BE MADE AS TO THE AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE SECURITY EVIDENCED HEREBY.

Any Common Stock issued upon conversion of any Note prior to the Resale Restriction Termination Date shall bear a legend in form and substance similar to the Restrictive Legend.

No transfer of any Note prior to the Resale Restriction Termination Date will be registered by the Note Registrar unless the applicable box on the Form of Assignment and Transfer has been checked.

Notwithstanding anything to the contrary contained in this Indenture or a Note (except for Section 2.05(d)), after the Resale Restriction Termination Date with respect to a Note, such Note (or security issued in exchange or substitution therefor) as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of such Note for

exchange to the Note Registrar in accordance with the provisions of this Section 2.05, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which shall not bear the Restrictive Legend and the CUSIP number for which shall be the applicable unrestricted CUSIP number.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.

The Depositary shall be a clearing agency registered under the Exchange Act. The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Note. Initially, the Global Notes shall be issued to the Depositary, registered in the name of Cede & Co., as the nominee of the Depositary, and deposited with the Trustee as custodian for DTC.

If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or unable to continue as depositary for the Global Notes and a successor depositary is not appointed within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default with respect to the Notes has occurred and is continuing, in each case, upon the request of the beneficial owner of the Notes, the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and a Company Order for the authentication and delivery of Notes, shall authenticate and deliver Physical Notes to each such beneficial owner of the related Notes (or a portion thereof) in an aggregate principal amount equal to the principal amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global Note to the Trustee such Global Note shall be canceled.

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

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

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

(d) The Company may cause the removal of the Restrictive Legend from any Global Note at any time on or after the Resale Restriction Termination Date by: (i) instructing the Trustee in writing to remove the Restrictive Legend from such Global Note; (ii) providing to the Trustee and the Depositary written notice to change the CUSIP number for the Notes to the applicable unrestricted CUSIP number; and (iii) complying with any Applicable Procedures for delegending or otherwise exchanging such Global Note for a Global Note not bearing the Restrictive Legend (including DTC’s mandatory exchange process, if applicable); whereupon the Restrictive Legend shall be deemed removed from any Global Notes and there shall be no requirement that any Common Stock into which such Global Notes are convertible bear a legend in form and substance similar to the Restrictive Legend, in each case without any further action on the part of the Holders.

(e) 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 Depositary participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(f) The Company shall not, and shall not permit any of its “affiliates” within the meaning of Rule 144, to resell any of the Notes that constitute “restricted securities” under Rule 144 that have been reacquired by them.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, 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 Company, to the Trustee and, if applicable, to the authenticating agent, such security or indemnity as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to the authenticating agent, evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or the authenticating agent, if applicable, may authenticate any such substituted Note and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, the authenticating agent may require. Upon the issuance of any substitute Note, the Company or the Trustee 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 that has matured or is about to mature or has been tendered for repurchase upon a Fundamental Change or is about to be converted shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to the authenticating agent, such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) 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, payment, conversion 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, payment or conversion of negotiable instruments or other securities without their surrender.

For greater certainty, every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is mutilated, destroyed, lost or stolen shall be issued as evidence of the same continuing indebtedness of the Company under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the substituted Note by virtue of such mutilation, destruction or loss.

Section 2.07. Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.05 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge

therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

For greater certainty, each Note issued pursuant to the provisions of this Section 2.07 in exchange for a temporary Note shall be issued as evidence of the same continuing indebtedness of the Company under this Indenture and in no circumstances is the Company obligated under the Indenture to repay the principal amount of the temporary Note by virtue of the exchange.

Section 2.08. Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such cancellation, shall deliver a written confirmation of such cancellation to the Company, at the Company’s written request. If the Company shall acquire any of the Notes, such acquisition shall not operate as satisfaction of the indebtedness represented by such Notes unless and until the same are delivered to the Trustee for cancellation.

Section 2.09. CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in all notices issued to Holders of the Notes 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 Company shall promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” numbers.

Any Notes that are, when issued, Restricted Securities shall be issued with a restricted CUSIP number. Until such time as the Restrictive Legend is removed from such Notes pursuant to the terms of this Indenture, the restricted CUSIP shall be the CUSIP number for such Notes. After the Company causes the removal of the Restrictive Legend from such Notes the CUSIP number for such Notes shall be an unrestricted CUSIP number.

Section 2.10. Additional Notes; Purchases. The Company may, without the consent of the Holders of the Notes and notwithstanding Section 2.01, issue additional Notes hereunder with the same terms and with the same CUSIP and ISIN number as the Notes initially issued hereunder in an unlimited aggregate principal amount, which shall form the same series with the Notes initially issued hereunder; provided that no such additional Notes may be issued unless they are fungible with the Notes initially issued hereunder for U.S. federal income tax purposes. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Opinion of Counsel (with respect to the enforceability of such additional notes) and an Officers’ Certificate to the effect that such issuance of additional Notes complies with the provisions of the Indenture (including this Section 2.10). In addition, the Company may, to the extent permitted by law, directly or indirectly (regardless of whether such

Notes are surrendered to the Company), from time to time purchase the Notes in open market purchases or negotiated transactions without prior notice to Holders. The Company shall cause any Notes so repurchased (other than Notes purchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08 and any Notes so repurchased by the Company shall be deemed to be no longer Outstanding under this Indenture.

So long as any Notes remain Outstanding, the Company agrees to maintain an office or agency with respect to such Notes and at such other location or locations as may be designated as provided in this Section 4.05, where (i) Notes may be presented for conversion (the Person accepting such conversions being the “Conversion Agent”), (ii) Notes may be presented for payment (whether upon repurchase, at the Maturity Date, upon acceleration or otherwise) (the Person accepting such presentments being the “Paying Agent”), (iii) Notes may be presented as herein above authorized for registration of transfer and exchange and (iv) notices and demands to or upon the Company in respect of the Notes and this Indenture may be given or served, such designation to continue with respect to such office or agency until the Company shall, by written notice signed by any two officers authorized to sign an Officers’ Certificate and delivered to the Trustee, designate some other office or agency for such purposes or any of them. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, notices and demands. The Company initially appoints the Corporate Trust Office of the Trustee as Conversion Agent and Paying Agent with respect to the Notes.

Section 4.06. Paying Agents.

The Trustee shall have no liability or responsibility for the action or inaction of any Paying Agent (that is not the Trustee).

(c) Notwithstanding anything in this Section 4.06 to the contrary, (i) the agreement to hold sums in trust as provided in this Section 4.06 is subject to the provisions of Section 3.02 and Section 3.03 and (ii) the Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms and conditions as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability with respect to such money.

Section 6.02. Acceleration of Maturity; Rescission and Annulment. If an Event of Default with respect to Outstanding Notes (other than an Event of Default specified Section 6.01(h) or Section 6.01(i) hereof in respect of the Company) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then-Outstanding Notes, by written notice to the Trustee, may declare the Notes due and payable at their principal amount plus any accrued and unpaid interest, and thereupon the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders by the appropriate judicial proceedings. Such declaration may be rescinded and annulled with the written consent of the Holders of a majority in aggregate principal amount of the then-Outstanding Notes, subject to the provisions of this Indenture.

If an Event of Default specified in Section 6.01(h) or Section 6.01(i) hereof occurs and is continuing, then all unpaid principal of, and accrued and unpaid interest on, the Outstanding Notes shall become immediately due and payable, without any declaration or other act on the part of the Trustee or any Holder.

Notwithstanding the foregoing, at the election of the Company, the sole remedy for an Event of Default specified in Section 6.01(f) relating to the failure by the Company to comply with its reporting obligations under Section 4.03 and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, shall (i) for the first 90 days after the occurrence of such an Event of Default, consist exclusively of the right to receive special interest on Notes (the “Special Interest”) at an annual rate equal to 0.25% per annum of the principal amount of the Outstanding Notes, and (ii) for the next 90 days after the expiration of such 90-day period, consist exclusively of the right to receive Special Interest on the Notes at an annual rate equal to 0.50% per annum of the principal amount of the Outstanding Notes.

The Special Interest shall be paid semiannually in arrears, with the first semiannual payment due on the first Interest Payment Date following the date on which the Special Interest began to accrue on any Notes. The Special Interest shall accrue on all Outstanding Notes from, and including, the date on which an Event of Default relating to a failure to comply with the reporting obligations under Section 4.03 or a failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act first occurs to, but not including, the 180th day thereafter (or such earlier date on which the Event of Default relating to such reporting obligations shall have been cured or waived). On such 180th day (or earlier, if such Event of Default is cured or waived pursuant to Section 6.04 prior to such 180th day), such Special Interest will cease to accrue and, if such Event of Default relating to such reporting obligations has not been cured or waived prior to such 180th day, the Notes shall be subject to acceleration as provided above in this Section 6.02. The provisions described in this paragraph shall not affect the rights of the Holders in the event of the occurrence of any other Event of Default. In the event the Company does not elect to pay Special Interest upon an Event of Default in accordance with this paragraph, the Notes will be subject to acceleration as provided in this Section 6.02. If the Company elects to pay Special Interest as the sole remedy for an Event of Default specified in Section 6.01(d) relating to the failure by the Company to comply with its obligations under Section 4.03 or any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, the Company shall notify in writing, in the manner provided for in Section 18.03, the Holders and the Trustee of such election at any time on or before the close of business on the date on which such Event of Default first occurs. If the Company fails to timely give such notice, the Notes shall be subject to acceleration as provided in this Section 6.02.

The Holders of a majority in aggregate principal amount of the then-Outstanding Notes by written notice to the Trustee may rescind and annul an acceleration and its consequences if:

(1) all existing Events of Default, other than the nonpayment of principal (including the Fundamental Change Repurchase Price, if applicable) of or interest on the Notes which has become due solely because of the acceleration, have been remedied, cured or waived; and

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction;

provided, however, that in the event such declaration of acceleration has been made based on the existence of an Event of Default under Section 6.01(g) hereof and such Event of Default has been remedied, cured or waived in accordance with Section 6.01(g) hereof, then, without any further action by the Holders, such declaration of acceleration shall be rescinded automatically and the consequences of such declaration shall be annulled. No such rescission or annulment shall affect any subsequent Default or impair any right consequent thereon.

Section 6.03. Other Remedies. If an Event of Default with respect to Outstanding Notes occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of, or interest on, the Notes or to enforce the performance of any provision of the Notes.

Section 6.04. Waiver of Past Defaults. The Holders, either (a) through the written consent of not less than a majority in aggregate principal amount of the Notes then

Outstanding or (b) by the adoption of a resolution, at a meeting of Holders of the Notes then Outstanding at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Notes represented at such meeting, may, on behalf of the Holders of all of the Notes, waive an existing Default or Event of Default, except a Default or Event of Default:

(1) in the payment of the principal of (including Fundamental Change Repurchase Price, if applicable), or interest on, any Note;

(2) in respect of the right to convert any Note in accordance with Article 13; or

(3) in respect of the covenants or provisions hereof which, under Section 9.02 hereof, cannot be modified or amended without the consent of the Holder of each Outstanding Note affected.

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; provided, however, that no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05. Control by Majority. The Holders, either (a) through the written consent of not less than a majority in aggregate principal amount of the Notes then Outstanding, or (b) by the adoption of a resolution, at a meeting of Holders of the Notes then Outstanding at which a quorum is present, by the Holders of at least a majority in aggregate principal amount of the Outstanding Notes represented at such meeting, shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, subject to the provisions of this Indenture. However, the Trustee may refuse to follow any direction that:

(a) conflicts with any law or with this Indenture;

(b) the Trustee determines may be unduly prejudicial to the rights of the Holders not joining therein; or

The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 6.06. Limitation On Suit. No Holder of any Note may pursue any remedy with respect to this Indenture or the Notes (including instituting any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver or trustee), except, in the case of a Default or Event of Default in the payment of the principal of (including the Fundamental Change Repurchase Price, if applicable), or interest on, the Notes or Default in the delivery of the shares of Common Stock and payment of cash in lieu of fractional shares due upon conversion of Notes, unless:

(a) such Holder has previously given written notice to the Trustee of an Event of Default that is continuing;

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

(c) such Holder or Holders have offered the Trustee security or indemnity reasonably satisfactory to the Trustee against any costs, liabilities or expenses incurred in complying with such request;

(d) the Trustee does not, within 60 days after receipt of the request and offer of indemnity, receive an inconsistent direction from the Holders of a majority in principal amount of the Notes; and

(e) the Trustee has failed to comply with the request for 60 days after the receipt of such request and an offer of indemnity.

A Holder of Notes may not use this Indenture to prejudice the rights of another Holder of Notes or to obtain a preference or priority over another Holder of Notes (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders).

Section 6.07. Unconditional Rights of Holders to Receive Payment and to Convert. In addition to the other rights and remedies set forth in this Article 6, the following shall apply with respect to the Notes under this Indenture.

Notwithstanding any other provision in this Indenture, the Holder of any Note shall have the right, which is absolute and unconditional, to receive payment of the principal amount (including the Fundamental Change Repurchase Price, if applicable), interest and the Make-Whole Fundamental Change Premium, if any, in respect of the Notes held by such Holder, on or after the respective due dates expressed in the Notes and this Indenture, and to convert such Note in accordance with Article 13, and to bring suit for the enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with Article 13, and shall not be impaired or affected without the consent of such Holder.

Section 6.08. Collection of Indebtedness and Suits For Enforcement By the Trustee. The Company covenants that if an Event of Default occurs under Section 6.01(a) or Section 6.01(b), then the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Notes, the whole amount then due and payable (as expressed therein or as a result of any acceleration effected pursuant to Section 6.02 hereof) on such Notes for principal (including the Fundamental Change Repurchase Price, if applicable) and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (including the Fundamental Change Repurchase Price, if applicable) and on any overdue interest, in each case at the rate borne by the Notes from the required payment date, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated.

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Notes by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

Section 6.09. Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or the property of the Company or its creditors, the Trustee (irrespective of whether the principal of the Notes (including the Fundamental Change Repurchase Price, if applicable) shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise, (1) to file and prove a claim for the whole amount of principal (including the Fundamental Change Repurchase Price, if applicable) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee hereunder) and of the Holders of Notes allowed in such judicial proceeding, and (2) to collect and receive any moneys or other property payable or deliverable on any such claim and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceedings is hereby authorized by each Holder of Notes to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Notes, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under this Indenture.

Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept, or adopt on behalf of any Holder of a Note, any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder of a Note in any such proceeding.

Section 6.10. Restoration of Rights and Remedies. If the Trustee or any Holder of a Note has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders of Notes shall be restored severally and respectively to their former positions hereunder and thereafter all rights

and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 6.11. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.06, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders of Notes is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.12. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or any acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders of Notes may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders of Notes, as the case may be.

Section 6.13. Application of Money Collected. Any money and property collected by the Trustee pursuant to this Article 6 shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money and property on account of principal (including the Fundamental Change Repurchase Price, if applicable) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

(i) prior to the occurrence of an Event of Default and after the curing or waiving of all such Events of Default that may have occurred:

(A) the duties and obligations of the Trustee shall with respect to the Notes be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable with respect to the Notes except for the performance of such duties and obligations as are specifically set forth in this Indenture and subject to the terms of this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Responsible Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(iv) none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate indemnity against such risk is not reasonably assured to it.

(k) the Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

In addition, the Trustee shall not be deemed to have knowledge of any Default or Event of Default except (1) any Event of Default occurring pursuant to Section 6.01(a) and 6.01(b) or (2) any Default or Event of Default of which the Trustee shall have received written notification in the manner set forth in this Indenture or a Responsible Officer of the Trustee shall have obtained actual knowledge. Delivery of reports, information and documents to the Trustee under Section 4.03 is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company’s compliance with any of their covenants thereunder (as to which the Trustee is entitled to rely conclusively on an Officers’ Certificate).

Section 7.03. Trustee Not Responsible for Recitals or Issuance or Notes.

Section 7.08. Corporate Trustee Required; Eligibility. There shall at all times be a Trustee with respect to the Notes issued hereunder which shall at all times be a corporation organized and doing business under the laws of the United States of America or any state or territory thereof or of the District of Columbia, or a corporation or other Person that is eligible to act as such under the Trust Indenture Act and permitted to act as trustee by the Securities and Exchange Commission, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least fifty million U.S. dollars ($50,000,000), and subject to supervision or examination by federal, state, territorial or District of Columbia authority.

If such corporation or other Person publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section 7.08, the combined capital and surplus of such corporation or other Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

If no successor trustee shall have been so appointed and have accepted appointment within 30 days after the mailing of such notice of resignation, the resigning Trustee, at the expense of the Company, may petition any court of competent jurisdiction for the appointment of a successor trustee with respect to the Notes, or any Holder who has been a bona fide Holder of Notes for at least six months may on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor trustee. Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

Such court may thereupon after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Notes pursuant to any of the provisions of this Section 7.09 shall become effective upon acceptance of appointment by the successor trustee as provided in Section 7.10.

Section 7.10. Acceptance of Appointment By Successor.

(a) In case of the appointment hereunder of a successor trustee with respect to all Notes, every such successor trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the written request of the Company or the successor trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all property and money held by such retiring Trustee hereunder. The trustee shall have no liability or responsibility for the action or inaction of any successor Trustee.

(b) In case of the appointment hereunder of a successor trustee with respect to some, but not all of the Notes, the Company, the retiring Trustee and each successor trustee with respect to such Notes shall execute and deliver an indenture supplemental hereto wherein each successor trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes to which the appointment of such successor trustee relates, (ii) shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall be responsible for any act or failure to act on the part of any other Trustee hereunder; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall with respect to the Notes to which the appointment of such successor trustee relates have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture, and each such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Notes to which the appointment of such successor trustee relates; but, on request of the Company or any successor trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor trustee, to the extent contemplated by such supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Notes to which the appointment of such successor trustee relates.

(c) Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) or (b) of this Section 7.10, as the case may be.

(d) No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible under this Article 7.

(e) Upon acceptance of appointment by a successor trustee as provided in this Section 7.10, the Company shall transmit notice of the succession of such trustee hereunder by mail, first-class postage prepaid, to the Holders, as their names and addresses appear upon the Note Register. If the Company fails to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company.

Section 7.11. Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or

substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 7.08 and eligible under the provisions of Section 7.08, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. 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.

Section 7.12. Preferential Collection of Claims Against the Company. The Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding any creditor relationship described in Section 311(b) of the Trust Indenture Act.

ARTICLE 8

Concerning the Holders

Section 8.01. Evidence of Action by Holders. Whenever in this Indenture it is provided that the Holders of a majority or specified percentage in aggregate principal amount of the Notes may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action the Holders of such majority or specified percentage of such Notes have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such Holders of such Notes in person or by agent or proxy appointed in writing.

If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by an Officers’ Certificate, fix in advance a record date for such Notes for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after the record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders 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 action, and for that purpose the Outstanding Notes shall be computed as of the record date; provided, however, that no such authorization, agreement or consent by such Holders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

Section 8.02. Proof of Execution by Holders. Subject to the provisions of Section 8.01, proof of the execution of any instrument by a Holder (such proof will not require

notarization) or his agent or proxy and proof of the holding by any Person of any of the Notes shall be sufficient if made in the following manner:

(a) The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.

(b) The ownership of Notes shall be proved by the Note Register or by a certificate of the Note Registrar thereof.

The Trustee may require such additional proof of any matter referred to in this Section 8.02 as it shall deem necessary.

Section 8.03. Who May be Deemed Owners. Prior to the due presentment for registration of transfer of any Note, the Company, the Trustee, any Paying Agent and any Note Registrar may deem and treat the Person in whose name such Note shall be registered upon the books of the Note Registrar as the absolute owner of such Note (whether or not such Note shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Note Registrar) for the purpose of receiving payment of or on account of the principal of (including the Fundamental Change Repurchase Price, if applicable), and interest on, such Note and for all other purposes; and neither the Company nor the Trustee nor any paying agent nor any Note Registrar shall be affected by any notice to the contrary.

Section 8.04. Certain Notes Owned by Company Disregarded. In determining whether the Holders of the requisite aggregate principal amount of Notes have concurred in any direction, consent or waiver under this Indenture, the Notes that are owned by the Company or any other obligor on the Notes or by any Affiliate of the Company or any other obligor on the Notes shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. The Notes so owned that 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 so to act with respect to such Notes and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

Section 8.05. Actions Binding on Future Holders. 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 majority or percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action, any Holder of a Note that 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, 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 Note issued in exchange therefor, on registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto

is made upon such Note. Any action taken by the Holders of the majority or percentage in aggregate principal amount of the Notes specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the Holders.

(j) reduce the percentage in aggregate principal amount of the Outstanding Notes required for the adoption of a resolution or the quorum required at any meeting of Holders of Notes at which a resolution is adopted.

It shall not be necessary for the consent of Holders of Notes under this Section 9.02 to approve the particular form of any proposed modification, amendment or waiver, but it shall be sufficient if such act shall approve the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company, or, at the written request of the Company, the Trustee, shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amendment, supplement or waiver.

Section 9.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article 9 or Section 10.01 this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the Company and the Holders of Notes affected thereby shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes.

Section 9.04. Notes Affected by Supplemental Indentures. Notes affected by a supplemental indenture, authenticated and delivered after the execution of such supplemental indenture pursuant to the provisions of this Article 9 or Section 10.01, may bear a notation in form approved by the Company as to any matter provided for in such supplemental indenture; provided such form meets the requirements of any securities exchange upon which such Notes may be listed. If the Company shall so determine, new securities so modified as to conform, in the opinion of the Board of Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared by the Company, authenticated by the Trustee and delivered in exchange for the Notes then Outstanding.

Section 9.05. Execution of Supplemental Indentures. Upon the request of the Company, accompanied by its Board Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Holders required to consent thereto as aforesaid (if such consent is required pursuant to this Article), the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. The Trustee, subject to the provisions of Section 7.01, shall receive and will be fully protected in conclusively relying upon an Officers’ Certificate and an Opinion of Counsel stating that any supplemental indenture executed pursuant to this Article is authorized or permitted by the terms of this Article 9 and constitutes a valid, binding and legal obligation, enforceable against the Company (subject to customary qualifications).

Promptly after the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall transmit by mail, first class postage prepaid, a notice, setting forth in general terms the substance of such supplemental indenture, to the Holders of all Notes affected thereby as their names and addresses appear upon the Note Register. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

(a) either (1) the Company shall be the resulting or surviving corporation or (2) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person which acquires by transfer or lease all or substantially all of the property and assets of the Company, shall (i) be a corporation, limited liability company, partnership or trust organized and existing under the laws of the United States of America or any State thereof or the District of Columbia, in each case, that is treated as a corporation for U.S. federal income tax purposes, and the property into which the Notes are convertible shall be the stock or other equity of an entity that is treated as a corporation for U.S. federal income tax purposes, and (ii) expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, the obligations of the Company under the Notes and this Indenture;

Additional Interest

Section 12.01. Additional Interest. (a) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes and ending on the date that is one year after the last date of the original issuance of the Notes, the Company either (i) fails to timely file any periodic report that the Company is required to file with the Commission under Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than reports on Form 8-K), or (ii) the Notes are not otherwise freely tradable pursuant to Rule 144 by Holders of the Notes other than the Company’s Affiliates, or under the terms of this Indenture or the Notes, then in either case (an “Additional Interest Event”), the Company shall pay additional interest on the Notes (the “Additional Interest ”). Such Additional Interest will accrue on the Notes at the rate of 0.25% per annum of the principal amount of Notes Outstanding for each day during the first 90-day period (or portion thereof) for which an Additional Interest Event has occurred and is continuing, which rate shall increase by an additional 0.25% per annum of the principal amount of the Notes, up to a maximum of 0.50% per annum of the principal amount of the Notes for each day thereafter for which an Additional Interest Event has occurred and is continuing.

(b) Unless:

(i) the Restrictive Legend on the Notes has been removed; or

(ii) the Notes are freely tradable pursuant to Rule 144 by Holders other than the Company’s Affiliates (without restrictions pursuant to U.S. securities law or the terms of this Indenture or the Notes), on or after the 365th day after the last date of original issuance of the Notes, an Additional Interest Event shall be deemed to have occurred and the Company shall pay Additional Interest on the Notes at an annual rate equal to 0.50% of the aggregate principal amount of the Notes Outstanding for each day until the Notes are freely tradable as described above.

(c) Notwithstanding the foregoing, the Company shall not be required to pay Additional Interest on any date if (i) the Company has filed a shelf registration statement for the resale of the Notes and any shares of Common Stock issued upon conversion of the Notes, (ii) such shelf registration statement is effective and usable by Holders of the Notes identified therein as selling securityholders for the resale of the Notes and any shares of Common Stock issued

upon conversion of the Notes and (iii) such Holders may register the resale of their Notes under such shelf registration statement on terms customary for the resale of convertible securities offered in reliance on Rule 144A.

(d) Under no circumstances will the combined rate of Additional Interest or Special Interest exceed 1.00% per annum.

(e) Additional Interest shall be payable in arrears on each Interest Payment Date following accrual in the same manner as regular interest on the Notes.

(f) The Company shall provide written notice to the Trustee prior to paying any Additional Interest.

ARTICLE 13

Conversion Of Notes

Section 13.01. Conversion Privilege and Conversion Rate. (a) Subject to and upon compliance with the provisions of this Article 13, each Holder of a Note shall have the right, at such Holder’s option, to convert any or all of such Holder’s Notes at the Conversion Rate during the periods set forth in Section 13.01(b).

(b) The conversion rights pursuant to this Article 13 shall commence on the Issue Date of the Notes and expire at the close of business on the Business Day immediately preceding the Maturity Date, subject to the provisions of this Indenture and, in the case of conversion of any Global Note, to any Applicable Procedures. If a Note is submitted or presented for purchase pursuant to Article 16, subject to the last paragraph of Section 13.03(b), such conversion right shall terminate at the close of business on the Business Day prior to the Fundamental Change Repurchase Date for such Note, as the case may be (unless the Company shall fail to make the Fundamental Change Repurchase Price payment when due in accordance with Article 16, if applicable, in which case the conversion right shall terminate at the close of business on the Business Day prior to the date such failure is cured and such Note is repurchased).

(c) A Holder may convert fewer than all of such Holder’s Notes only if (i) the principal amount of Notes converted is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not so converted is in a minimum principal amount of $2,000. Provisions of this Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note.

(d) A Holder of Notes is not entitled to any rights of a holder of Common Stock until such Holder has converted its Notes into Common Stock, and only to the extent such Notes are deemed to have been converted into Common Stock pursuant to this Article 13.

(e) The Conversion Rate shall be adjusted in certain instances as provided in Section 13.02 and Section 13.07.

(f) By delivering the number of shares of Common Stock issuable on conversion to the Trustee, plus a cash payment for any fractional share, the Company shall be deemed to have

satisfied its obligation to pay the principal amount of the Notes so converted and its obligation to pay accrued and unpaid interest attributable to the period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than canceled, extinguished or forfeited).

Section 13.02. Make-Whole Fundamental Change Premium. (a) If the Make-Whole Fundamental Change Effective Date for any Make -Whole Fundamental Change shall have occurred, then the Company shall calculate and pay a “Make- Whole Fundamental Change Premium” to the Holders of the Notes who convert their Notes in connection with such Make-Whole Fundamental Change by adding such Make-Whole Fundamental Change Premium to the Conversion Rate for such Notes. A conversion of Notes shall be deemed for these purposes to be “in connection with” such Make-Whole Fundamental Change if the relevant Notice of Conversion delivered pursuant to Section 13.03(a) is received by the Conversion Agent on, or subsequent to, the relevant Make-Whole Fundamental Change Effective Date but before the related Fundamental Change Purchase Date. The Fundamental Make-Whole Change Premium shall be in addition to, and not in substitution for, any cash, securities or other assets otherwise due to Holders of Notes upon conversion. The number of additional shares of Common Stock per $1,000 principal amount of Notes constituting the Make-Whole Fundamental Change Premium shall be determined by reference to the table set forth in Section 13.02(b), based on the Make-Whole Fundamental Change Effective Date and the Stock Price. If the holders of Common Stock receive only cash in the Make-Whole Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock in connection with such Make-Whole Fundamental Change. Otherwise, the Stock Price shall be equal to the average Last Reported Sale Price of the Common Stock over the ten Trading Day period ending on the Trading Day immediately preceding, and excluding, the applicable Make-Whole Fundamental Change Effective Date.

(b) The following table sets forth the number of Additional Shares to be received per $1,000 principal amount of Notes pursuant to this Section 13.02(b) for each Stock Price and Make-Whole Fundamental Change Effective Date set forth below:


Effective Date	$27.67		$35.00		$38.05		$45.00		$50.00		$60.00		$80.00		$100.00		$150.00		$200.00

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

(i) if the Stock Price is between two Stock Prices in the table above or the Make-Whole Fundamental Change Effective Date is between two Make-Whole Fundamental Change Effective Dates in the table above, the Make-Whole Fundamental Change Premiums shall be determined by a straight-line interpolation between the Make-Whole Fundamental Change Premiums set forth for the higher and lower Stock Prices

and the earlier and later Make-Whole Fundamental Change Effective Dates, as applicable, based on a 365-day year;

(ii) if the Stock Price is greater than $200.00 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (c) below), no Make-Whole Fundamental Change Premium shall be added to the Conversion Rate; and

(iii) if the Stock Price is less than $27.67 per share (subject to adjustment in the same manner as the Stock Prices set forth in the column headings of the table above pursuant to subsection (c) below), no Make-Whole Fundamental Change Premium shall be added to the Conversion Rate.

(c) The Stock Prices set forth in the first row of the table above in Section 13.02(b) shall be adjusted, as of any date on which the Conversion Rate of the Notes is adjusted other than an adjustment to the Conversion Rate by adding the Make-Whole Fundamental Change Premium. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The Make-Whole Fundamental Change Premiums set forth in the table above shall be adjusted in the same manner as the Conversion Rate as set forth in Section 13.07 hereof, other than as a result of an adjustment to the Conversion Rate by adding the Make-Whole Fundamental Change Premium.

(d) The Company, or, at the written request of the Company, the Trustee, shall mail written notice of the anticipated Make-Whole Fundamental Change Effective Date of any Make-Whole Fundamental Change to the Holders (with a copy to the Trustee if applicable) as promptly as practicable following the date the Company publicly announces such Make-Whole Fundamental Change, but in no event less than 20 days prior to the anticipated Make-Whole Fundamental Change Effective Date (the “Make-Whole Fundamental Change Notice”).

(e) Notwithstanding the foregoing, in no event shall the Conversion Rate exceed 36.1402 per $1,000 principal amount as a result of this Section 13.02, subject to proportional adjustment in the same manner as the Conversion Rate as set forth in Section 13.07 hereof.

(f) The Make-Whole Fundamental Change Premium shall be delivered upon the settlement date for the conversion.

Section 13.03. Conversion Procedure. (a) To convert a Physical Note, a Holder must (1) complete and manually sign the Notice of Conversion on the back of the Note, or facsimile of such Notice of Conversion, and deliver such Notice of Conversion to the Conversion Agent, which shall become irrevocable upon receipt by the Conversion Agent, (2) surrender the Note to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Note Registrar or the Conversion Agent, (4) pay an amount equal to the interest payable on the next Interest Payment Date to which the Holder is not entitled as required by Section 13.03(c) and (5) pay all transfer or similar taxes, if required pursuant to Section 13.05. Anything herein to the contrary notwithstanding, in the case of Global Notes,

Notices of Conversion may be delivered and such Notes may be surrendered for conversion in accordance with clauses (3), (4) and (5) of this Section 13.03(a) and the Applicable Procedures as in effect from time to time. The date on which the Holder satisfies all the applicable requirements set forth in this Section 13.03(a) is the “Conversion Date.”

(b) Each conversion shall be deemed to have been effected as to any Notes surrendered for conversion on the Conversion Date, the person in whose name the shares of Common Stock shall be issuable upon conversion shall be deemed to be the holder of record of such Common Stock as of the close of business on such Conversion Date, and the Company shall deliver the consideration due in respect of any conversion on the third Business Day immediately following the relevant Conversion Date; provided, however, that no surrender of a Note on any Conversion Date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open. Upon conversion of a Note, such person shall no longer be the Holder of such Note and (i) such Note will cease to be Outstanding, (ii) interest will cease to accrue on such Note and (iii) all other rights of such person in respect of such Note will terminate (other than the right to receive the consideration due upon conversion of such Note). Except as set forth in this Indenture, no payment or adjustment will be made for dividends or distributions declared or made on shares of Common Stock issued upon conversion of a Note prior to the issuance of such shares.

A Holder that has delivered a Fundamental Change Repurchase Notice pursuant to Section 16.01 with respect to a Note may not surrender such Note for conversion until such Holder has withdrawn the Fundamental Change Repurchase Notice in accordance with Section 16.01.

(c) Holders of Notes surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the open of business on the next succeeding Interest Payment Date will receive the semiannual interest payable on the principal amount of such Notes being surrendered for conversion on the corresponding Interest Payment Date notwithstanding the conversion. Upon surrender of any such Notes for conversion, such Notes shall also be accompanied by payment in funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date (but excluding any overdue interest on the principal amount of such Note so converted if any overdue interest exists at the time such Holder surrenders such Note for conversion); provided, however, that no such payment need be made (i) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or prior to the next succeeding Interest Payment Date, or (ii) if conversion occurs after the last Regular Record Date prior to the Maturity Date. Except as otherwise provided in this Section 13.03(c), no payment or adjustment will be made for accrued interest on a converted Note and any such accrued interest shall be deemed satisfied and extinguished.

(d) Subject to Section 13.03(c), nothing in this Section 13.03 shall affect the right of a Holder in whose name any Note is registered at the close of business on a Regular Record Date

to receive the interest payable on such Note on the related Interest Payment Date in accordance with the terms of this Indenture and the Notes. If a Holder converts more than one Note at the same time, the number of shares of Common Stock issuable upon the conversion (and the amount of any cash in lieu of fractional shares pursuant to Section 13.04) shall be based on the aggregate principal amount of all Notes so converted.

(e) In the case of any Note which is converted in part only, upon such conversion the Company shall execute and the Trustee shall authenticate and deliver to the Holder thereof, without service charge, a new Note or Notes of authorized denominations in an aggregate principal amount equal to, and in exchange for, the unconverted portion of the principal amount of such Note.

Section 13.04. Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. Instead of any fractional share of Common Stock which would otherwise be issued upon conversion of any Note or Notes (or specified portions thereof), the Company shall pay a cash adjustment in respect of such fraction (calculated to the nearest one-100th of a share) in an amount equal to the same fraction of the Last Reported Sale Price of the Common Stock as of the Business Day preceding the Conversion Date.

Section 13.05. Taxes on Conversion. Except as provided in the next sentence, the Company shall pay any and all documentary, stamp or similar issue or transfer tax due and duties on the issuance of shares of Common Stock upon conversion of Notes pursuant hereto. A Holder delivering a Note for conversion shall be liable for and shall be required to pay any tax or duty which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the Holder of the Note or Notes to be converted, and no such issue or delivery shall be made unless the Person requesting such issue has paid to the Company the amount of any such tax or duty, or has established to the satisfaction of the Company that such tax or duty has been paid.

Section 13.06. Company to Provide Common Stock. (a) The Company shall, prior to issuance of any Notes hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all Outstanding Notes into shares of Common Stock.

(b) All shares of Common Stock delivered upon conversion of the Notes shall be newly issued shares, shall be duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive or similar rights and free of any lien or adverse claim as the result of any action by the Company.

Section 13.07. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Conversion Rate if Holders of the Notes participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of the Common Stock and solely as a result of holding the Notes, in any of the transactions described in this Section 13.07, without having to convert their Notes,

as if they held a number of shares of Common Stock equal to the Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder.

(a) If the Company issues shares of Common Stock as a dividend or distribution on shares of Common Stock, or effects a share split or share combination, the Conversion Rate shall be adjusted based on the following formula:


CR₁ = CR₀ x	OS₁
	OS₀

where,


CR₀	=	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as the case may be;

CR₁	=	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately after the open of business on the effective date of such share split or share combination, as the case may be;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution, or immediately prior to the effective date of such share split or share combination, as the case may be; and

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

Any adjustments made pursuant to this Section 13.07(a) shall become effective immediately after (x) the open of business on the Ex-Dividend Date for such dividend or distribution or (y) the open of business on the effective date of such split or combination, as applicable. If any dividend or distribution described in this Section 13.07(a) is declared but not so paid or made, effective as of the date the Board of Directors determines not to pay such dividend or distribution, the new Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company distributes to all or substantially all holders of Common Stock any rights, options or warrants entitling them to purchase, for a period of not more than 45 days after the Ex-Dividend Date for the distribution, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the ten consecutive Trading Day period ending on the Trading Day immediately preceding the announcement date for such distribution, the Conversion Rate shall be adjusted based on the following formula:


CR₁ = CR₀ x		OS₀ + X
CR₁ = CR₀ x		OS₀ + Y

where,


CR₀	=	the Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;

CR₁	=	the new Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution;

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


Y		=		the number of shares of Common Stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on the Trading Day immediately preceding the declaration date for such distribution.

For purposes of this Section 13.07(b), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than the average of the Last Reported Sale Prices of the Common Stock for the applicable ten consecutive Trading Day period, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise thereof, with the value of such consideration if other than cash, to be determined by the Board of Directors.

Any adjustment made pursuant to this Section 13.07(b) shall be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business on the Ex-Dividend Date for such distribution. To the extent that shares of Common Stock are not delivered after the expiration of such rights, options or warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if the Ex-Dividend Date for such distribution had not occurred.

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

(i) dividends, distributions (including share splits), rights, options or warrants as to which an adjustment is effected in Section 13.07(a), Section 13.07(b) or Section 13.07(e);

(ii) dividends or distributions covered by Section 13.07(d);

(iii) dividends or distributions that constitute Reference Property following an event described in Section 13.11; and

(iv) Spin-Offs to which the provisions set forth below in this Section 13.07(c) shall apply,

then the applicable Conversion Rate shall be adjusted based on the following formula:


CR₁ = CR₀ x		SP₀
CR₁ = CR₀ x		SP₀ – FMV

where,


CR₀		=		the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such distribution;


CR₁	=	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such distribution;

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

FMV	=	the fair market value (as determined in good faith by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding share of Common Stock as of the open of business on the Ex-Dividend Date for such distribution.

Any adjustment made under the portion of this Section 13.07(c) above shall 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 Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

If “FMV” as set forth above is equal to or greater than “SP₀” as set forth above, in lieu of the foregoing adjustment, Holders of the Notes shall receive, in respect of each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of Common Stock, the amount and kind of the Company’s Capital Stock, evidences of its indebtedness, other assets or property of the Company or rights, options or warrants to acquire the Company’s Capital Stock or other securities that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for the distribution.

With respect to an adjustment pursuant to this Section 13.07(c) where there has been a payment of a dividend or other distribution on the Common Stock of shares of the Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit that are, or, when issued, will be, traded or quoted on any national or regional securities exchange or other market (a “Spin-Off”), the applicable Conversion Rate shall instead be adjusted based on the following formula:


CR₁ = CR₀ x		FMV₀ + MP₀
CR₁ = CR₀ x		MP₀

where,


CR₀	=	the applicable Conversion Rate in effect immediately prior to the end of the Valuation Period;

CR₁	=	the applicable Conversion Rate in effect immediately after the end of the Valuation Period;

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock of the Company or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Common Stock were to such Capital Stock or similar equity interest) over the first ten consecutive Trading Day period immediately following the Ex-Dividend Date for such Spin-Off (such period, the “Valuation Period”); and

MP₀	=	the average of the Last Reported Sale Prices of Common Stock over the Valuation Period.

Such adjustment shall occur immediately after the tenth Trading Day immediately following the Ex-Dividend Date of such Spin-Off; provided that, for purposes of determining the Conversion Rate in respect of any conversion during the ten Trading Days following the Ex-

Dividend Date of any Spin-Off, references within the previous paragraph related to “Spin-Offs” to ten Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the Ex-Dividend Date of such Spin-Off and the relevant Conversion Date. If any such dividend or distribution described in the preceding paragraph of this Section 13.07(c) is declared but not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

For purposes of this Section 13.07(c) (and subject in all respect to Section 13.14), rights, options or warrants distributed by the Company to all holders of its 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 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 13.07(c) (and no adjustment to the Conversion Rate under this Section 13.07(c) shall 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 Conversion Rate shall be made under this Section 13.07(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 Conversion Rate under this Section 13.07(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 Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Conversion 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 Conversion Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 13.07(a), Section 13.07(b) and this Section 13.07(c), any dividend or distribution to which this Section 13.07(c) is applicable that also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 13.07(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 13.07(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 13.07(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 13.07(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 Conversion Rate adjustment required by Section 13.07(a) and Section 13.07(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 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 such dividend, distribution, share split or share combination, as the case may be” within the meaning of Section 13.07(a) or “outstanding immediately prior to the open of business on the Ex-Dividend Date for such distribution” within the meaning of Section 13.07(b).

(d) If any cash dividend or distribution is made to all or substantially all holders of Common Stock, the Conversion Rate shall be adjusted based on the following formula:


CR₁ = CR₀ x		SP₀
CR₁ = CR₀ x		SP₀– C

where,


CR₀	=	the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such dividend or distribution;

CR₁	=	the applicable Conversion Rate in effect immediately after the open of business on the Ex-Dividend Date for such dividend or distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the ten consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such dividend or distribution; and

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

An adjustment to the Conversion Rate made pursuant to this Section 13.07(d) shall become effective immediately after the open of business on the Ex-Dividend Date for the applicable dividend or distribution. If any dividend or distribution described in this Section 13.07(d) is declared but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

If “C” as set forth above is equal to or greater than “SP₀” as set forth above, in lieu of the foregoing adjustment, each Holder of a Note shall receive, for each $1,000 principal amount of Notes, at the same time and upon the same terms as holders of shares of Common Stock, the amount of cash that such Holder would have received if such Holder owned a number of shares of Common Stock equal to the applicable Conversion Rate in effect immediately prior to the open of business on the Ex-Dividend Date for such cash dividend or distribution.

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


CR₁ = CR₀ x		AC + (SP₁ x OS₁)
CR₁ = CR₀ x		OS₀ x SP₁

where,


CR₀	=	the applicable Conversion Rate in effect immediately prior to the open of business on the Trading Day next succeeding the Expiration Date;

CR₁	=	the applicable Conversion Rate in effect immediately after the open of business on the Trading Day next succeeding the Expiration Date;

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

OS₀	=	the number of shares of Common Stock outstanding immediately prior to time (the “Expiration Time”) such tender or exchange offer expires (prior to giving effect to such tender offer or exchange offer);

OS₁	=	the number of shares of Common Stock outstanding immediately after the Expiration Time (after giving effect to such tender offer or exchange offer); and

SP₁	=	the Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the Expiration Date.

The adjustment to the Conversion Rate under this Section 13.07(e) shall become effective immediately following the close of business on the Trading Day next succeeding the Expiration Date. If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

Section 13.08. When No Adjustment is Required. (a) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this Section 13.08(a) shall be carried forward and taken into account in any subsequent adjustment and any carry forward amount shall be paid to the Holder upon conversion regardless of the 1% threshold. All calculations under this Article 13 shall be made to the nearest cent or to the nearest 1/10,000th of a share.

(b) If the application of the foregoing formulas in Section 13.07 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate shall be made (except on account of share combinations).

(c) No adjustment to the Conversion Rate shall be made unless as specifically set forth in Section 13.07 and Section 13.02. Without limiting the foregoing, no adjustment to the Conversion Rate need be made:

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

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

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

(iv) upon the issuance of Rights under the Rights Plan unless, prior to conversion, the Rights issued under the Rights Plan have separated from the Common Stock;

(v) for a change in the par value of the Common Stock; or

(vi) for accrued and unpaid interest (including any Special Interest and Additional Interest, if applicable).

Section 13.09. Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is required to be adjusted pursuant to this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment, the adjusted Conversion Rate and the manner of computing it. Failure to mail such notice or any defect therein shall not affect the validity of any such adjustment. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Rate, the Trustee may assume without inquiry that the Conversion Rate has not been adjusted and that the last Conversion Rate of which it has knowledge remains in effect.

Section 13.10. Notice of Certain Transactions. In the event that there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a written notice stating the proposed effective date. The Company shall mail such notice at least 20 days before such proposed effective date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in this Section 13.10.

Section 13.11. Effect of Reclassification, Consolidation, Merger or Sale On Conversion Privilege. If any of the following events occur:

(a) any recapitalization, reclassification or change of the outstanding shares of Common Stock (other than changes resulting from a subdivision or combination);

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

(c) any sale, conveyance or lease to any third party of all or substantially all of the property and assets of the Company and its Subsidiaries; or

(d) any statutory share exchange,

in each case as a result of which holders of Common Stock shall be entitled to receive stock, other securities or other property or assets (including cash or any combination thereof) (the “Reference Property”) with respect to or in exchange for such Common Stock, the Holders of the Notes then Outstanding shall be entitled thereafter to convert those Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which they would have owned or been entitled to receive upon such transaction had such notes been converted into Common Stock immediately prior to such transaction. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in such transaction, the Reference Property shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such election. The Company shall notify the Holders of the weighted average as soon as practicable after such determination is made. The Company may not become a party to any such transaction unless its terms are consistent with the preceding. None of the foregoing provisions shall affect the right of a Holder of Notes to convert its Notes into shares of Common Stock prior to the effective date of such transaction.

The above provisions of this Section 13.11 shall similarly apply to successive recapitalizations, reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 13.11 applies to any event or occurrence, Section 13.07 hereof shall not apply.

Section 13.12. Trustee’s Disclaimer. (a) The Trustee shall have no duty to determine, or liability in connection therewith, when an adjustment under this Article 13 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in conclusively relying upon, an Officers’ Certificate, including the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 13.09. Unless and until the Trustee receives such Officers’ Certificate delivered pursuant to Section 13.09, the Trustee may assume without inquiry that no such adjustment has been made and the last Conversion Rate of which the Trustee has knowledge remains in effect. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Notes, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 13.

(b) The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 13.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in conclusively relying upon, the Officers’ Certificate and Opinion of Counsel, with respect thereto which the Company are obligated to file with the Trustee pursuant to Section 13.11 and Section 10.01, respectively.

Section 13.13. Voluntary Increase; NYSE Compliance. (a) Subject to Section 9.01(e), the Company from time to time may increase the Conversion Rate, to the extent permitted by law and subject to any applicable stockholder approval requirements pursuant to the listing standards of The New York Stock Exchange or such other United States securities exchange on which the Common Stock is traded, by any amount for any period of at least 20 days, if the Board of Directors determines that such increase shall be in the Company’s best interests. The Company may (but is not required to) make such increase in the Conversion Rate (in addition to others provided in this Indenture) as the Board of Directors deems advisable to avoid or diminish any income tax to holders of Common Stock resulting from a dividend or distribution of stock, or rights to acquire stock, or similar event; provided, however, that in no event may the Company increase the Conversion Rate such that it causes the Conversion Price to be less than the par value of a share of Common Stock. The Company shall provide at least 15 days’ written notice to Holders and the Trustee of any increase under this Section 13.13.

(b) The Company may not take any voluntary actions that would result in an adjustment to the Conversion Rate pursuant to Section 13.07 without complying, if applicable, with the stockholder approval rules of The New York Stock Exchange and any similar rule of any United States securities exchange on which the Common Stock is listed at the relevant time. In accordance with such listing standards, this restriction shall apply at any time when the Notes are Outstanding, regardless of whether the Company then has a class of securities listed on The New York Stock Exchange.

Section 13.14. Rights Plan. To the extent that the Company has a Rights Plan in effect upon conversion of the Notes into Common Stock, the Holders shall receive upon conversion of the Notes, the Rights under the Rights Plan, unless prior to conversion, the Rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all or substantially all holders of Common Stock shares of the Company’s Capital Stock, evidences of indebtedness or other assets or property of ours or rights, options or warrants to acquire the Company’s Capital Stock or other securities as described in Section 13.07(c) above, subject to readjustment in the event of the expiration, termination or redemption of such Rights.

Repurchase Of Notes Upon a Fundamental Change

Section 16.01. Repurchase of Notes at Option of the Holder Upon a Fundamental Change. (a) If a Fundamental Change occurs prior to the Maturity Date, each Holder of a Note shall have the right, at the option of the Holder, to require the Company to

repurchase all or any of such Holder’s Notes at the Fundamental Change Repurchase Price, on the date specified by the Company that is not less than 20 days and not more than 35 days after the date of the Fundamental Change Company Notice pursuant to Section 16.01(b) (the “Fundamental Change Repurchase Date”). If the Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the Company shall pay accrued and unpaid interest to the Holder of a Note of record at the close of business on such Regular Record Date and the Fundamental Change Repurchase Price shall be 100% of the principal amount of the Notes to be repurchased. A Holder may require the Company to repurchase fewer than all of such Holder’s Notes only if (i) the principal amount of Notes to be repurchased is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be repurchased is in a minimum principal amount of $2,000.

(b) On or before the 15th day after the Fundamental Change Effective Date, the Company, or, at the request of the Company, the Trustee, shall mail a written notice by first-class mail of the occurrence of the Fundamental Change, and of the repurchase right arising therefrom, to the Trustee, Paying Agent and to each Holder at the address shown in the Note Register of the Note Registrar (and to beneficial owners as required by applicable law) (the “Fundamental Change Company Notice”). Simultaneously with providing such Fundamental Change Company Notice, the Company shall publish a notice containing the information that is required in the Fundamental Change Company Notice in a newspaper of general circulation in The City of New York or publish information on a website of the Company or through such other public medium the Company may use at that time. The Fundamental Change Company Notice shall set forth the Holder’s right to require the Company to purchase the Notes and specify:

(i) the events causing such Fundamental Change;

(ii) the date of such Fundamental Change;

(iii) the last date by which the Fundamental Repurchase Notice must be delivered to elect the repurchase option pursuant to this Section 16.01;

(iv) the Fundamental Change Repurchase Price;

(v) the Fundamental Change Repurchase Date;

(vi) the name and address of each Paying Agent and Conversion Agent, if applicable;

(vii) that the Notes with respect to which a Fundamental Change Repurchase Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Repurchase Notice in accordance with the terms of this Indenture; and

(viii) the procedures that the Holder must follow to require the Company to repurchase its Notes under this Section 16.01.

At the Company’s written request, the Trustee shall give such Fundamental Change Company Notice in the Company’s name and at the Company’s expense; provided that, unless

otherwise agreed by the Trustee, the Company makes such request at least five Business Days prior to the date by which such Fundamental Change Company Notice must be given to the Holders in accordance with this Section 16.01; provided, further, that the text of such Fundamental Change Company Notice shall be prepared by the Company. If any of the Notes is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Notes.

No failure of the Company to give the foregoing notices or defect therein shall limit any Holder’s right to exercise its right to cause the Company to repurchase such Holder’s Notes pursuant to this Section 16.01.

(c) Repurchases of Notes under this Article 16 shall be made upon delivery to the Paying Agent by the Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in the Form of Fundamental Change Repurchase Notice in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes, if the Notes are Global Notes, in each case before the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date.

Each Fundamental Change Repurchase Notice shall state:

(A) in the case of Physical Notes, the certificate numbers of the Notes to be delivered for repurchase;

(B) the portion of the principal amount of the Notes to be repurchased, which must be $1,000 or an integral multiple thereof (provided that any portion of a Holder’s Note not to be repurchased is in the minimum principal amount of $2,000); and

(C) that the Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture

provided, however, that if the Notes are Global Notes, the Repurchase Notice must comply with appropriate Depositary procedures..

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Repurchase Notice contemplated by this Section 16.01 shall have the right to withdraw, in whole or in part, such Fundamental Change Repurchase Notice at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.02.

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

Section 16.02. Withdrawal of Fundamental Change Repurchase Notice.

(a) A Fundamental Change Repurchase Notice may be withdrawn (in whole or in part) by means of a written notice of withdrawal delivered to the Corporate Trust Office of the Paying Agent in accordance with this Section 16.02 at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date specifying:

(i) the principal amount of the Notes with respect to which such notice of withdrawal is being submitted;

(ii) if Physical Notes have been issued, the certificate number of the Note in respect of which such notice of withdrawal is being submitted; and

(iii) the principal amount, if any, of such Note that remains subject to the original Fundamental Change Repurchase Notice, which portion must be in principal amounts of $1,000 or an integral multiple of $1,000 (provided that any portion of a Holder’s Note not to be repurchased is in the minimum principal amount of $2,000);

provided, however, that if the Notes are Global Notes, the notice must comply with appropriate procedures of the Depositary.

Section 16.03. Deposit of Fundamental Change Repurchase Price. (a) The Company shall deposit with the Trustee (or other Paying Agent appointed by the Company, or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.06(b)) on or prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, as the case may be, an amount of money sufficient to repurchase all of the Notes to be repurchased at the appropriate Fundamental Change Repurchase Price. Subject to receipt of funds and/or Notes by the Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for repurchase will be made on the later of (i) the Fundamental Change Repurchase Date with respect to such Note (provided the Holder has satisfied the conditions in Section 16.01) and (ii) the time of book-entry transfer or the delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the Holder thereof in the manner required by Section 16.01, by mailing checks for the amount payable to the Holders of such Notes entitled thereto as they shall appear in the Note Register; provided, however, that payments to the Depositary shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

(b) If by 11:00 a.m. New York City time, on the Fundamental Change Repurchase Date the Trustee (or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the Notes or portions thereof that are to be repurchased on such Fundamental Change Repurchase Date then (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) and (iii) all other rights of the Holders of such Notes will terminate (other than the right to receive the Fundamental Change Repurchase Price).

Section 16.04. Repayment to the Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 16.03 exceeds the aggregate Fundamental Change Repurchase Price of the Notes or portions thereof that the

Company is obligated to repurchase pursuant to this Article 16, then promptly after the relevant Fundamental Change Repurchase Date the Paying Agent shall return any such excess cash to the Company.

Section 16.05. Notes Repurchased In Part. Upon surrender of any Note that is to be repurchased only in part in accordance with Section 16.01, and promptly after the Fundamental Change Repurchase Date, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, a new Note or Notes, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $2,000 principal amount or greater integral multiples of $1,000), in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not repurchased.

Section 16.06. Covenant to Comply with Applicable Laws Upon Repurchase of Notes. In connection with any repurchase offer pursuant to this Article 16, the Company shall, if required:

(a) comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act;

(b) file a Schedule TO or any successor or similar schedule; and

(c) otherwise comply with all federal and state securities laws in connection with any offer by the Company to repurchase the Notes;

in each case, so as to permit the rights and obligations under this Article 16 to be exercised in the time and in the manner specified in this Article 16.

[FORM OF REVERSE OF NOTE]

THE GREENBRIER COMPANIES, INC.
3.50% Convertible Senior Note due 2018

This Note is one of a duly authorized issue of the Notes of the Company, designated as its 3.50% Convertible Senior Notes due 2018 (herein called the “Notes”), initially limited to the aggregate principal amount of $230,000,000, all issued or to be issued under and pursuant to an Indenture dated as of April 5, 2011 (herein called the “Indenture”), between the Company and U.S. Bank National Association (herein called the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes. Additional Notes may be issued in an unlimited aggregate principal amount, subject to certain conditions specified in the Indenture.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of and accrued and unpaid interest, if any, on all Notes may be declared, by either the Trustee or Holders of not less than 25% in aggregate principal amount of Notes then outstanding, and upon said declaration shall become, due and payable, in the manner, with the effect and subject to the conditions and certain exceptions set forth in the Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price and the principal amount on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note. The Company will pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts.

The Indenture contains provisions permitting the Company and the Trustee in certain circumstances, without the consent of the Holders of the Notes, and in other circumstances, with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time outstanding, evidenced as in the Indenture provided, to execute supplemental indentures modifying the terms of the Indenture and the Notes as described therein. It is also provided in the Indenture that, subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes at the time outstanding may on behalf of the Holders of all of the Notes waive any past Default or Event of Default under the Indenture and its consequences.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (including the Fundamental Change Repurchase Price, if applicable), and accrued and unpaid interest on, this Note at the place, at the respective times, at the rate and in the lawful money herein prescribed or to satisfy its obligation to convert the Notes.

The Notes are issuable in registered form without coupons in denominations of $2,000 principal amount and greater integral multiples of $1,000. At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations

provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any tax, assessments or other governmental charges that may be imposed in connection therewith as a result of the name of the Holders of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

The Notes are not subject to redemption at the option of the Company and there will be no sinking fund.

Upon the occurrence of a Fundamental Change, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes or any portion thereof on the Fundamental Change Repurchase Date at a price equal to the Fundamental Change Repurchase Price. However, a Holder may only require the Company to repurchase fewer than all of such Holder’s Notes if (i) the principal amount of Notes to be repurchased is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be repurchased is in a minimum principal amount of $2,000.

Subject to the provisions of the Indenture, during certain periods and upon the occurrence of certain conditions specified in the Indenture, the Holder hereof has the right, at its option, prior to the close of business on the Business Day immediately preceding the Maturity Date, to convert any Notes or portion thereof, into shares of Common Stock (together with cash in lieu of fractional shares) at a Conversion Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture; provided that a Holder may only convert fewer than all of such Holder’s Notes if (i) the principal amount of Notes to be converted is an integral multiple of $1,000 and (ii) the portion of such Holder’s Notes not to be converted is in a minimum principal amount of $2,000.

Terms used in this Note and defined in the Indenture are used herein as therein defined.
