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 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 purchases, conversions, transfers or exchanges. 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 instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal (including any Fundamental Change Purchase Price) 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 $1,000 principal amount and multiples thereof. Each Note shall be dated the date of its authentication and shall bear interest from the date of issuance of such Note or from the most recent date to which interest has been paid or duly provided for, to the date the principal amount of such Note is paid or deemed paid, as the case may be. Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

Subject to Section 13.02, the Person in whose name any Note (or its Predecessor Note) is registered on the Note Register on the date of issuance of such Note shall be entitled to receive the interest payable on the Maturity 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 Notes in certificated form (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 ten Business Days prior to the Maturity 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 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 delivered, or in the case of Notes in certificated form, 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 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.

If the Company makes a distribution of property to holders of Common Stock that would be taxable to them as a dividend for United States federal income tax purposes and the Conversion Rate is increased, the Company may offset any withholding tax applicable to non-United States Holders against cash payments of interest payable on the Notes.

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.

Section 2.05. Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary; Automatic Exchange. (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 and bearing such restrictive legends as may be required by this Indenture.

Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the 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 will 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) Unless the Company and a beneficial holder of any Notes otherwise agree that such beneficial holder’s interests therein be issued as a Note in certificated form, so long as the Notes are eligible for book-entry settlement with the Depositary, unless otherwise required by law or except as provided in Error! Reference source not found., 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 Note in certificated form 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. 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) Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Error! Reference source not found.), 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, upon the request of the

beneficial owner of the Notes, the Company will execute, and the Trustee, upon receipt of an Officer’s Certificate and a Company Order for the authentication and delivery of Notes, will authenticate and deliver Notes in definitive form 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.

Notes in certificated form issued in exchange for all or a part of the Global Note pursuant to this Error! Reference source not found. shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such Notes in certificated form 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 purchased 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 Notes in certificated form, converted, canceled, purchased or transferred to a transferee who receives Notes in certificated form therefor or any Note in certificated form 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 will 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.

The Trustee shall have no obligation or duty to monitor, determine or inquire into compliance with any restriction on transfer imposed under the Indenture or applicable law with respect to any transfer of any Note (including any transfers between or among Depositaries or beneficial owners of interests in any Global Notes) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements of the Indenture.

(d) The Company may cause the removal of the legends required by Sections 2.05(c) from any Global Note at any time on or after the Resale Restriction Date by: (i) instructing the Trustee to remove the such legends 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 (iv) 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 any legends otherwise required by Section 2.05(c) shall be removed from any Global Notes without any further action on the part of the Holders.

Section 2.06. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its written request 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 purchase 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 or payment or conversion or purchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment or 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 will 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 Notes in certificated form, 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 Notes in certificated form but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the 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 Notes in certificated form. Without unreasonable delay, the Company will execute and deliver to the Trustee or such authenticating agent Notes in certificated form (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 Notes in certificated form. 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 Notes in certificated form 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 will 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, purchase, 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 disposition, shall deliver a written confirmation of such disposition 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 will promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” numbers.

Section 2.10. Purchases.

The Company may from time to time purchase the Notes in open market purchases or negotiated transactions without prior notice to Holders. Any Notes purchased by the Company shall be deemed to be no longer Outstanding under this Indenture.

ARTICLE 3

SATISFACTION AND DISCHARGE

Section 3.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officer’s Certificate cease to be of further

effect, and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) the Company delivers to the Trustee all Outstanding Notes (other than Notes replaced pursuant to Section 2.06) for cancellation; or (ii) the Company has irrevocably deposited with the Trustee or delivered to Holders of Notes, as applicable, after the Notes have become due and payable, whether at the Maturity Date, or any Fundamental Change Purchase Date, or upon conversion or otherwise, cash and/or (in the case of conversion) shares of Common Stock (together with cash in lieu of fractional shares), as applicable, sufficient to pay all of the Outstanding Notes and all other sums payable under this Indenture by the Company; and (b) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 7.06 shall survive such satisfaction and discharge.

Section 3.02. Deposited Monies To Be Held In Trust. Subject to Section 3.03 hereof, all monies deposited with the Trustee pursuant to Section 3.01 hereof shall be held in trust and applied by it to the payment, either directly or through any Paying Agent (including the Company if acting as its own Paying Agent), to the Holders for the payment or repurchase of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal, premium, if any, and interest. All monies deposited with the Trustee pursuant to Section 3.01 hereof (and held by it or any Paying Agent) for the payment of Notes subsequently converted shall be returned to the Company upon request of the Company.

Section 3.03. Return Of Unclaimed Monies. Subject to applicable escheat laws, the Trustee and the Paying Agent shall pay to the Company upon written request any money held by them for the payment of principal of or accrued and unpaid interest on the Notes that remains unclaimed for two years after the date upon which such payment shall have become due. Notwithstanding the foregoing, the Trustee and Paying Agent shall have the right to withhold payment of such money to the Company until the Trustee or Paying Agent at the expense of the Company mails to each Holder, a notice stating that such money shall be repaid to the Company if unclaimed after a date no less than 30 days from the mailing. After payment to the Company by the Trustee or Paying Agent, all liability of the Trustee and the Paying Agent with respect to such money shall cease, and Holders entitled to the money must look to the Company for payment as general creditors, subject to applicable law.

ARTICLE 4

PARTICULAR COVENANTS OF THE COMPANY

Section 4.01. Payment of Principal and Interest. (a) The Company shall promptly make all payments in respect of the Notes on the dates and in the manner provided in the Notes and this Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent holds by 10:00 a.m. (New York City time) on that date money or securities, deposited by or on behalf of the Company sufficient to make the payment. The Company shall, to the fullest extent permitted by law, pay interest in immediately available funds on overdue principal amount and interest at the annual rate borne by the Notes compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand.

(b) Payment of the principal of and interest, if any, on the Notes shall be made at the office or agency of the Company maintained for that purpose, which shall initially be at the Trustee’s Corporate Trust Office, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, subject to Section 2.03, the Company may pay principal and interest in respect of any Note in certificated form by check or wire transfer payable in such money. Notwithstanding the foregoing, so long as the Notes are registered in the name of a Depositary or its nominee, all payments thereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

Section 4.02. Corporate Existence. Subject to Article 10 hereof, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and rights (charter and statutory); provided, however, that the Company shall not be required to preserve any such right or franchise if the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

Section 4.03. Rule 144A Information Requirement and Reports. (a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof shall, at such time, constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, upon written request, provide to any Holder, beneficial owner or prospective purchaser of such Notes or any shares of Common Stock issued upon conversion of such Notes, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act.

(b) The Company shall furnish to the Trustee within 15 calendar days after the Company is required to file any documents or reports with the Commission pursuant to Sections 13 or 15(d) of the Exchange Act (giving effect to all applicable grace periods provided under the Exchange Act including that provided by Rule 12b-25 under the Exchange Act) copies of such documents or reports. Any such document or report that the Company files with the Commission through the Commission’s XXXXX system shall be deemed furnished to the Trustee for purposes of this Section 4.03(b) at the time such documents are filed or furnished via the Commission’s XXXXX system, provided that the Trustee shall have no responsibility for determining whether such filing has taken place, nor shall the Trustee have any liability for the timeliness or content of any filing or report hereunder.

Section 4.04. Compliance Certificate. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2015) an Officer’s Certificate stating whether or not, to the knowledge of such officer, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. Within five Business Days of an Officer of the Company coming to have actual knowledge of a Default or Event of Default, regardless of the date, the Company shall deliver an Officer’s Certificate to the Trustee specifying such Default or Event of Default and the nature and status thereof.

Section 4.05. Maintenance of Office or Agency.

If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the 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. (a) If the Company shall appoint one or more paying agents for the Notes, other than the Trustee, the Company will cause each such paying agent to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.06:

(i) that it will hold all sums held by it as such agent for the payment of the principal of (and premium, if any) or interest on the Notes (whether such sums have been paid to it by the Company or by any other obligor of such Notes) in trust for the benefit of the Persons entitled thereto;

(ii) that it will give the Trustee notice of any failure by the Company to make any payment of the principal of (and premium, if any) or interest on the Notes when the same shall be due and payable;

(iii) that it will, at any time during the continuance of any failure referred to in the preceding paragraph (a)(ii) above, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent; and

(iv) that it will perform all other duties of paying agent as set forth in this Indenture.

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(g) or 6.01(h) 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(g) or 6.01(h) 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(d) 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% 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% of the principal amount of the Outstanding Notes.

The Special Interest shall be paid semi-annually in arrears, with the first semi-annual 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 will 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 17.03, 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.

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 Purchase 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(e) hereof and such Event of Default has been remedied, cured or waived in accordance with Section 6.01(e) 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. The Trustee may maintain a proceeding even if it does not possess any of the securities or does not produce any of them in the proceeding.

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 or premium, if any, 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 or premium on, if any, or interest on the 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, and shall have offered to the Trustee indemnity satisfactory to the Trustee, to pursue the remedy;

(c) no direction inconsistent with such written request has been given to the Trustee by the Holders of a majority in aggregate principal amount of the Notes then Outstanding (or such amount as shall have acted at a meeting pursuant to the provisions of this Indenture);

(d) such Holder or Holders have offered the Trustee security or indemnity satisfactory to the Trustee against any costs, liabilities or expenses incurred in complying with such request; 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 Purchase Price, if applicable), and interest, in respect of the Notes held by such Xxxxxx, 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 Purchase Price, if applicable) and premium, if any, and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal (including the Fundamental Change Purchase Price, if applicable) and premium, if any, 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 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 Purchase Price, if applicable) and premium, if any, 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 2.05(d), 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 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 Purchase Price, if applicable) or premium, if any, 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:

THIRD: Any remaining amounts shall be repaid to the Company.

Section 6.14. Undertaking For Costs. All parties to this Indenture agree, and each Holder of any Note by such Holder’s acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.14 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Notes then Outstanding, or to any suit instituted by any Holder of any Note for the enforcement of the payment of the principal (including the Fundamental Change Purchase Price, if applicable) of or premium, if any, or interest on any Note on or after the stated maturity expressed in such Note (or, in the case of exercise of a repurchase right in connection with a Fundamental Change, on or after the Fundamental Change Purchase Date) or for the enforcement of the right to convert any Note in accordance with Article 13.

Section 6.15. Waiver of Stay or Extension Laws. The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim to take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 6.16. Notice of Default. If any Default or any Event of Default occurs and is continuing and if such Default or Event of Default is actually known to a Responsible Officer of the Trustee, the Trustee shall within 90 days of the occurrence of a Default or Event of Default, mail to each Holder notice of all uncured Defaults or Events of Default known to the Trustee, unless such Default or Event of Default has been cured; provided, however, that, except in the case of a default in the payment of the principal of (including upon repurchase) or premium, if any, or interest on any Note, the Trustee shall be protected in withholding such notice if the Trustee in good faith determines that the withholding of such notice is in the best interest of such Holders.

(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

The Company also covenants to indemnify the Trustee (and its officers, agents, directors and employees) for, and to hold it harmless against, any loss, liability or expense incurred without negligence or willful misconduct on the part of the Trustee and arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses of defending itself against any claim of liability in the premises.

(b) The obligations of the Company under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for reasonable expenses, disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the benefit of the Holders.

(c) The Company covenants and agrees to indemnify the Trustee for, and hold it harmless from and against, any loss, liability, damages, claims, costs

Section 7.07. Reliance on Officer’s Certificate and Opinions. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it reasonably necessary or desirable that a matter be proved or established prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s Certificate and Opinion of Counsel delivered to the Trustee and such certificate or opinion, in the absence of negligence or willful misconduct on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.

Section 7.08. Disqualification; Conflicting Interests. If the Trustee has or shall acquire any “conflicting interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the Company shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act.

Section 7.09. 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

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 7.09, 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. The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee. In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 7.09, the Trustee shall resign promptly in the manner and with the effect specified in Section 7.10.

Section 7.10. Resignation and Removal; Appointment of Successor.

Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee with respect to the Notes by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor trustee. 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.

(i) the Trustee shall fail to comply with the provisions of Section 7.08 after written request therefor by the Company or by any Holder who has been a bona fide Holder of Notes for at least six months;

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 7.09 and shall fail to resign after written request therefor by the Company or by any such Holder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove the Trustee with respect to the Notes and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or any Holder who has been a bona fide Holder of Notes for at least six months may, on behalf of that Xxxxxx and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of 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.

Section 7.11. 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 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 7.11, 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 7.11, the Company shall transmit notice of the succession of such trustee hereunder by mail, first class postage prepaid or in accordance with the Applicable Procedures, 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 7.12. 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 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 7.09, 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 7.13. 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. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the Trust Indenture Act to the extent included therein.

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 Officer’s 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 7.01, 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 Company 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, premium, if any, and (subject to Section 2.03) 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 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.

ARTICLE 9

Section 9.02. With Consent of Holders. Except as provided below in this Section 9.02, this Indenture or the Notes may be amended or supplemented, and noncompliance by the Company in any particular instance with any provision of this Indenture or the Notes may be waived, in each case (i) with the written consent of the Holders of at least a majority in aggregate principal amount of the Notes then Outstanding or (ii) 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 a majority in aggregate principal amount of the Outstanding Notes represented at such meeting.

Without the written consent or the affirmative vote of each Holder of an affected Note, an amendment, supplement or waiver to this Indenture or the Notes may not:

(i) 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, provided such form meets the requirements of any securities exchange upon which such Notes may be listed, as to any matter provided for in such supplemental indenture. 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, will be entitled to receive and will be fully protected in relying upon an Officer’s Certificate and an Opinion of Counsel stating that any supplemental indenture executed pursuant to this Article is authorized or permitted by, and conforms to, the terms of this Article 9, constitutes a valid, binding and legal obligation, enforceable against the Company (subject to customary qualifications) and that it is proper for the Trustee under the provisions of this Article 9 to join in the execution thereof.

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.

CONVERSION OF NOTES

Section 13.01. Conversion Privilege and Conversion Rate. (a) 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 unless previously repurchased, 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 15, subject to the last paragraph of Section 13.02(b), such conversion right shall terminate at the close of business on the Business Day prior to the Fundamental Change Purchase Date for such Note (unless the Company shall fail to make the Fundamental Change Purchase Price payment when due in

accordance with Article 15, 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).

(b) Provisions of this Indenture that apply to conversion of all of a Note also apply to conversion of a portion of a Note.

(c) 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.

(d) The Conversion Rate shall be adjusted in certain instances as provided in Section 13.06.

(e) [Reserved].

(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 will 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 Issue Date through the Conversion Date (which amount will be deemed satisfied and extinguished).

Section 13.02. Conversion Procedure. (a) To convert a Note in certificated form, 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 and (4) pay all transfer or similar taxes, if required pursuant to Section 13.04. 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) and (4) of this Section 13.02(a) and the Applicable Procedures as in effect from time to time. The date on which the Holder satisfies all the requirements set forth in this Section 13.02(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 and 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. 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 Purchase Notice pursuant to Section 15.01 with respect to a Note may not surrender such Note for conversion until such Holder has withdrawn the Fundamental Change Purchase Notice in accordance with Section 15.01(c).

(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 13.02(c), nothing in this Section 13.02 shall affect the right of a Holder in whose name any Note is registered on the Issue Date to receive the interest payable on such Note on the Maturity 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 13.03) 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. A Note may be converted in part, but only if the principal amount of such part is an integral multiple of $1,000 and the principal amount of such Note to remain Outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof.

Section 13.03. Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of any Note or Notes. If more than one Note shall be surrendered for conversion at one time by the same Holder, the number of full shares which shall be issued upon conversion thereof shall be computed on the

basis of the aggregate principal amount of the Notes (or specified portions thereof) so surrendered. 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 Trading Day preceding the Conversion Date.

Section 13.04. Taxes on Conversion. Except as provided in the next sentence, the Company will 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 will 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 13.05. 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 13.06. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:

(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 will be adjusted based on the following formula:


CR	= CR₀ ×	OS
CR	= CR₀ ×	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;

CR	=	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 such dividend, distribution, share split or share combination, as the case may be; and

OS	=	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 13.06(a) shall become effective immediately on or after (x) the open of business on the Ex-Dividend Date for such dividend or distribution or (y) the effective date of such split or combination, as applicable. If any dividend or distribution described in this Section 13.06(a) is declared but not so paid or made, 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 holders of Common Stock any rights 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 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the declaration date for such distribution, the Conversion Rate will be adjusted based on the following formula:


CR	= CR₀ ×	OS₀ + X
CR	= CR₀ ×	OS₀ + Y

where,


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

CR	=	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 or warrants; and

Y	=	the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the declaration date for such distribution.

For purposes of this Section 13.06(b), in determining whether any rights 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 10 consecutive Trading-Day period, there shall be taken into account any consideration received by the Company for such rights 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. If any right or warrant described in this Section 13.06(b) is not exercised prior to the expiration of the exercisability thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such right or warrant had not been so issued. Any adjustment made pursuant to this Section 13.06(b) shall become effective immediately after the Ex-Dividend Date for the applicable distribution.

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

(i) dividends or distributions (including share splits) as to which an adjustment is effected in Section 13.06(a) or Section 13.06(b);

(ii) dividends or distributions covered by Section 13.06(d);

(iii) dividends or distributions that constitute Reference Property following an event pursuant to Section 13.10; and

(iv) Spin-Offs to which the provisions set forth below in this Section 13.06(c) shall apply,

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


CR	= CR₀ ×	SP₀
CR	= CR₀ ×	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;

CR	=	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 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

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

If the then fair market value of the portion of the shares of Capital Stock, evidences of indebtedness or other assets or property so distributed applicable to one share of Common Stock is equal to or greater than the average of the Last Reported Sales Prices of the Common Stock over the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution, in lieu of the foregoing adjustment, adequate provisions shall be made so that each Holder of a Note shall have the right to receive on conversion in respect of each Note held by such Holder, in addition to any amounts to which such Holder is entitled to receive, the amount and kind of securities and assets such Holder would have received had such Holder already owned a number of shares of Common Stock equal to the applicable Conversion Rate immediately prior to the open of business on the Ex-Dividend Date for the distribution of the securities or assets.

With respect to an adjustment pursuant to this Section 13.06(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 will instead be adjusted based on the following formula:


		CR = CR₀ ×		FMV + MP₀
		CR = CR₀ ×		MP₀

where,


CR₀	=	the applicable Conversion Rate in effect immediately prior to the tenth Trading Day immediately following the effective date for such Spin-Off;

CR	=	the applicable Conversion Rate in effect immediately after the open of business on the tenth Trading Day immediately following the effective date for such Spin-Off;

FMV	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading-Day period immediately following the effective 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, and including, the effective date of such Spin-Off; provided that, for purposes of determining the Conversion Rate in respect of any conversion during the 10 Trading Days following the effective date of any Spin-Off, references within this Section 13.06(c) related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the relevant Conversion Date.

If any such dividend or distribution described in this Section 13.06(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.

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


		CR = CR₀ ×		SP₀
		CR = CR₀ ×		SP₀ – C

where,


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

CR	=	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 10 consecutive Trading-Day period ending on, and including, the Trading Day immediately preceding the Ex-Dividend Date for such 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 13.06(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 13.06(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 the amount in cash per share of Common Stock so paid or distributed is equal to or greater than the average of the Last Reported Sales Prices of the Common Stock over the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such cash dividend or distribution, in lieu of the foregoing adjustment, adequate provisions shall be made so that each Holder of a Note shall have the right to receive on conversion in respect of each Note held by such Holder, in addition to any amounts to which such Holder is entitled to receive, the amount in cash such Holder would have received had such Holder already owned a number of shares of Common Stock equal to the applicable Conversion Rate immediately prior to the record 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 (other than tender offers or exchange offers not subject to Rule 13e-4 of the Exchange Act or odd lot tender offers), 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:


		CR = CR₀ ×		AC + (SP × OS)
		CR = CR₀ ×		OS₀ × SP

where,


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

CR	=	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);

OS	=	the number of shares of Common Stock outstanding immediately after the expiration time (after giving effect to such tender offer or exchange offer); and

SP	=	the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the Expiration Date.

The adjustment to the Conversion Rate under this Section 13.06(e) shall become effective immediately following the tenth Trading Day next succeeding the date such tender offer or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the 10 Trading Days following the date that any tender or exchange offer expires, references within this Section 13.06(e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date such tender or exchange offer expires and the relevant Conversion Date. If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or exchange offer but are 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.

(f) Notwithstanding the foregoing, if a Conversion Rate adjustment becomes effective on any Ex-Dividend Date pursuant to Section 13.06(a) through Section 13.06(e), and a Holder that has converted its Notes on or after such Ex-Dividend Date and on or prior to the related record date would be treated as the record holder of the Common Stock as of the related Conversion Date based on an adjusted Conversion Rate for such Ex-Dividend Date, then, notwithstanding Section 13.06(a) through Section 13.06(e), the Conversion Rate adjustment relating to such Ex-Dividend Date will not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of the Common Stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

Section 13.07. 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 13.07(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 one-hundredth of a share.

(b) Without limiting the foregoing provisions of Section 13.06, no adjustment will be made thereunder, nor shall an adjustment be made to the ability of a Holder to convert, for any distribution described therein if the Holder will otherwise participate in the distribution without conversion of such Holder’s Notes as if such Holder held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Notes held by such Holder, without having to convert its Notes. Further, if the application of the foregoing formulas in Section 13.06 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (except on account of share combinations).

(c) No adjustment to the Conversion Rate will be made unless as specifically set forth in Section 13.06. 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) for a change in the par value of the Common Stock; or

(v) for accrued and unpaid interest (including any Special Interest).

Section 13.08. 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 Officer’s 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 Officer’s 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 13.09. 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 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 13.09.

Section 13.10. 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 a changes resulting from a subdivision or combination),

(b) any consolidation, merger, or combination involving the Company with another corporation, or

(c) any sale, conveyance or lease to any other corporation of all or substantially all of the property and assets of the Company,

(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 will 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 will 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 13.10 shall similarly apply to successive recapitalizations, reclassifications, mergers, consolidations, statutory share exchanges, combinations, sales and conveyances.

If this Section 13.10 applies to any event or occurrence, Section 13.06 hereof shall not apply.

The Company shall not become a party to any such transaction unless its terms are consistent with the foregoing. None of the foregoing provisions shall affect the right of a Holder to convert the Notes as set forth in Section 13.01 prior to the effective time of such transaction.

Section 13.11. 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 relying upon, an Officer’s Certificate, including the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 13.08. Unless and until the Trustee receives such Officer’s Certificate delivered pursuant to Section 13.08, 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 13.10, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officer’s Certificate and Opinion of Counsel, with respect thereto which the Company are obligated to file with the Trustee pursuant to Section 13.10 and Section 10.01, respectively.

Section 13.12. Voluntary Increase; Nasdaq Compliance. 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 Nasdaq Stock Market 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. The Company may 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, and the Company provides 15 days’ prior written notice of any increase in the Conversion Rate to the Trustee and the Holders: 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 may not take any voluntary actions that would result in an adjustment to the Conversion Rate pursuant to Section 13.06 without complying, if applicable, with the stockholder approval rules of the NASDAQ Global Market and any similar rule of any stock 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 NASDAQ Global Market.

Section 13.13. Rights Plan. To the extent that the Company has a Rights Plan in effect upon conversion of the Notes into Common Stock, the Holder will receive upon conversion of the Notes in respect of which the Company has elected to deliver Common Stock, if applicable, the Rights under the Rights Plan, unless prior to any conversion, the Rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of Common Stock shares of the Company’s Capital Stock, evidences of indebtedness or assets as

described in Section 13.06(c) above, subject to readjustment in the event of the expiration, termination or redemption of such Rights. In lieu of any such adjustment, the Company may amend such applicable Rights Plan to provide that upon conversion of the Notes the Holders will receive, in addition to the Common Stock issuable upon such conversion, the Rights which would have attached to such Common Stock if the Rights had not become separated from the Common Stock under such applicable Rights Plan.

Section 13.14. Exchange in Lieu of Conversion. (a) Notwithstanding anything in this Indenture to the contrary, when a Holder surrenders Notes for conversion, the Company may, at its election, direct the Conversion Agent to surrender, on or prior to the second Business Day immediately following the Conversion Date (assuming for purposes of this Section 13.14 that the date such Holder surrenders such Notes for conversion is the Conversion Date for such Notes), such Notes to a financial institution designated by the Company (a “Financial Institution”) for exchange in lieu of conversion.

(b) In order to accept any such Notes surrendered for conversion, the Financial Institution must agree to deliver, in exchange for such Notes, shares of Common Stock (and cash in lieu of fractional shares) equal to the consideration due upon conversion under Section 13.01(a) (the “Exchange Settlement Property”).

(c) By the close of business on the second Business Day immediately following the Conversion Date, the Company must notify the Holder surrendering Notes for conversion that it has directed the Financial Institution to make an exchange in lieu of conversion and the Financial Institution shall be required to notify the Conversion Agent whether it will deliver the Exchange Settlement Property upon exchange.

(d) If the Financial Institution accepts any such Notes, it shall deliver the Exchange Settlement Property to the Conversion Agent and the Conversion Agent shall deliver such Exchange Settlement Property to the applicable Holder no later than the third Business Day following the Conversion Date. Any Notes exchanged by the Financial Institution shall remain Outstanding, subject to Applicable Procedures.

(e) If the Financial Institution agrees to accept any Notes for exchange but does not timely deliver the related consideration, or if the Financial Institution does not accept the Notes for exchange, the Company shall deliver such conversion consideration as if the Company had not made an exchange election.

The Company’s designation of the Financial Institution to which the Notes may be submitted for exchange does not require the Financial Institution to accept any Notes. The Company shall not pay any consideration to, or otherwise enter into any agreement with, the financial institution designated as the Financial Institution for or with respect to such designation.

ARTICLE 14

NO OPTIONAL REDEMPTION

Section 14.01. No Optional Redemption. The Notes shall not be redeemable by the Company prior to the Maturity Date, and are not subject to redemption through the operation of any sinking fund.

ARTICLE 15

REPURCHASE OF NOTES

Section 15.01. 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 portion of the Notes of such Holder equal to $1,000 principal amount (or an integral multiple thereof) at the Fundamental Change Purchase 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 15.01(b) (the “Fundamental Change Purchase Date”).

(b) On or before the tenth day after the Fundamental Change Effective Date, the Company, or, at the request of the Company, the Trustee, shall mail a written notice of the occurrence of the Fundamental Change, and of the repurchase right arising therefrom, to the Trustee, Paying Agent and to each Holder (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 15.01;

(iv) the Fundamental Change Purchase Price;

(v) the Fundamental Change Purchase 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 Notice has been delivered by a Holder may be converted only if the Holder withdraws the Fundamental Change Purchase 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 15.01.

At the Company’s 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 (5) Business Days prior to the date by which such Fundamental Change Company Notice must be given to the Holders in accordance with this Section 15.01; 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. The Trustee shall not be obligated on behalf of the Company to 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.

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 15.01.

(c) A Holder may exercise its rights specified in this Section 15.01 upon delivery of (1) the Note to be repurchased, duly endorsed for transfer, together with (2) a written purchase notice and the form entitled “Fundamental Change Purchase Notice” on the reverse of the Note duly completed and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form onto the Paying Agent (in the case of Notes held in book-entry form, in accordance with DTC’s Applicable Procedures) of the exercise of

such rights (a “Fundamental Change Purchase Notice”) to the Paying Agent at any time on or before the close of business on the Fundamental Change Purchase Date, subject to extension to comply with applicable law.

(i) The Fundamental Change Purchase Notice shall state: (A) the certificate number (if such Note is held in certificated form) of the Note which the Holder will deliver to be repurchased (or, if the Note is held in global form, any other items required to comply with the Applicable Procedures), (B) the portion of the principal amount of the Note which the Holder will deliver to be repurchased and (C) that such Note shall be repurchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions specified in the Notes and in this Indenture.

(ii) The delivery of a Note for which a Fundamental Change Purchase Notice has been timely delivered to any Paying Agent, on or before the Business Day immediately preceding the Fundamental Change Purchase Date (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor (or, if the Note is held in global form, any items required to comply with the Applicable Procedures).

(iii) The Company shall only be obliged to purchase, pursuant to this Section 15.01, a portion of a Note if the principal amount of such portion is $1,000 or an integral multiple of $1,000 (provisions of this Indenture that apply to the purchase of all of a Note also apply to the purchase of such portion of such Note).

ARTICLE 18

SUBORDINATION

Section 18.01. Subordination.

(a) The Company covenants and agrees, and each Holder, by accepting a Note, likewise covenants and agrees, that all payments on the Notes, including the payment of principal, Fundamental Change Purchase Price and interest (including Special Interest) on the Notes, will be subordinated to the extent hereinafter set forth, to the prior payment in full in cash (or other payment satisfactory to the holders of Designated Senior Debt) of all of the Designated Senior Debt and the subordination is for the benefit of and enforceable by the holders of the Designated Senior Debt.

(b) Upon any distribution of the Company’s assets upon any dissolution, winding up, liquidation, reorganization, bankruptcy, assignment for the benefit of holders or any other marshaling of assets, or similar proceeding, the payment of the principal, Fundamental Change Purchase Price of and interest (including Special Interest) on, the Notes will be subordinated in right of payment to the same extent as set forth in Section 18.01(a) above to the prior payment in full in cash (or other payment satisfactory to the holders of Designated Senior Debt) of all of the Designated Senior Debt. The Company shall promptly notify holders of Designated Senior Debt if payment of the Notes is accelerated because of an Event of Default or if a Fundamental Change occurs.

Notwithstanding the foregoing, the right of Holders to receive any distributions, which (x) are provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under any applicable Bankruptcy Law relating to the Company and consented to by the holders of the Designated Senior Debt and (y) take the form of the Company’s equity interests or the Company’s indebtedness that is subordinated in right of payment to Designated Senior Debt then outstanding to at least the same extent of the Notes, shall not be subordinated to the prior payment of any Designated Senior Debt or otherwise subject to the subordination provisions of this Section 18.01, and none of the Holders will be obligated to pay over any such distributions to any holder of Designated Senior Debt. The Company may not make any payment on the Notes if:

(i) at the time any default in the payment of principal, premium, interest or other amounts due on Designated Senior Debt when due, whether at maturity, upon mandatory repurchase, acceleration, or otherwise, and the default has not been cured or waived (a “Payment Default”); or

(ii) a default, other than a payment default, on any Designated Senior Debt occurs and is continuing that permits holders of Designated Senior Debt to accelerate its maturity, and the Trustee receives a notice of such default (a “Payment Blockage Notice”) from a holder of Designated Senior Debt electing to effect a payment blockage under this Indenture (a “Nonpayment Default”).

The Company may resume payments and distributions on the Notes:

(i) in case of a Payment Default, upon the date on which such default is cured or waived or ceases to exist; and

(ii) in case of a Nonpayment Default, the earlier of (A) the date on which such Nonpayment Default is cured or waived, (B) 91 days after the date the Designated Senior Debt is paid in full in cash (or other payment satisfactory to the holders of the Designated Senior Debt), (C) 179 days after the date on which the Payment Blockage Notice is received by the Trustee, if the maturity of the Designated Senior Debt has not been accelerated and there is no Payment Default, or (D) the date the Payment Blockage Notice has been rescinded.

No Nonpayment Default that existed or was continuing on the date of delivery of any Payment Blockage Notice shall be the basis for any later Payment Blockage Notice unless such default shall have been cured or waived for a period of not less than 90 consecutive days.

(c) If the Trustee or any Holder receives any payment or distribution of the Company’s assets in contravention of the subordination provisions of this Section 18.01 before all Designated Senior Debt is paid in full in cash or other payment satisfactory to holders of Designated Senior Debt, then such payment or distribution will be held for the benefit of holders of Designated Senior Debt or their representatives and paid over to them to the extent necessary to make payment in full in cash or payment satisfactory to the holders of Designated Senior Debt of all unpaid Designated Senior Debt.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Designated Senior Debt and shall not be liable to any such holders if the Trustee shall in good faith mistakenly pay over or distribute to Holders or to the Company or to any other person cash, property or securities to which any holders of Designated Senior Debt shall be entitled by virtue of this Article or otherwise. With respect to the holders of Designated Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article and no implied covenants or obligations with respect to holders of Designated Senior Debt shall be read into this Indenture against the Trustee.

Nothing in this Section 18.01 shall prohibit the conversion or exchange of any or all of the Notes into or for shares of Common Stock, including cash payments in lieu of fractional shares of common stock.

The Notes are issuable in registered form without coupons in denominations of $1,000 principal amount and multiples thereof. 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 shall not be redeemable by the Company prior to the Maturity Date, and are not subject to redemption through the operation of any sinking fund.

Subject to the provisions of 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 that is $1,000 or a multiple 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.
