For the avoidance of doubt, any matter requiring consent under this Supplemental Indenture or otherwise impacting only the Securities and no other Debt Securities shall only require the consent of the Holders of the Securities to the extent required by and in accordance with the terms and conditions of Article X hereof. The provisions of this Supplemental Indenture shall supersede any conflicting provisions in the Base Indenture.

ARTICLE II

THE SECURITIES

Section 2.01 Form And Dating.

The Securities and the Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Supplemental Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange or automated quotation system rule or regulation or usage. The Company shall provide any such notations, legends or endorsements to the Trustee in writing. Each Security shall be dated the date of its authentication.

(a) Global Securities. All of the Securities are initially being offered and sold in reliance on an effective registration statement under the Securities Act and shall be issued initially in the form of a Global Security, which shall be deposited with the Trustee, at its Corporate Trust Office, as custodian for The Depository Trust Company (“DTC” and such depositary, or successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto), for the accounts of participants in the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of a Global Security may from time to time be increased or decreased by adjustments made on the records of the Securities Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures.

(b) Global Securities In General. Each Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Securities from time to time endorsed thereon and that the aggregate amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect issuances, replacements, exchanges, purchases or conversions of such Securities. Any adjustment of the aggregate principal amount of a Global Security to reflect the amount of any increase or decrease in the amount of outstanding Securities represented thereby shall be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.12 and shall be made on the records of the Trustee and the Depositary.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute

-10-

owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (1) 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 (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

(c) Book Entry Provisions. The Company shall execute and the Trustee shall, in accordance with this Section 2.01(c), authenticate and deliver initially one or more Global Securities that (1) shall be registered in the name of the Depositary or its nominee, (2) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions and (3) shall bear a legend substantially to the following effect:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE 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.”

Section 2.02 Execution And Authentication.

(a) The aggregate principal amount of Securities which may be authenticated and delivered under the Indenture is limited to Securities in the aggregate original principal amount of $37.5 million, which shall be issued on the date hereof subject to the terms and conditions set forth in the Securities Purchase Agreement and in compliance with the Indenture.

-11-

(b) An Officer shall sign the Securities for the Company by manual or facsimile signature. Typographic and other minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security that has been authenticated and delivered by the Trustee.

(c) If an officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

(d) A Security shall not be valid until an authorized signatory of the Trustee by manual signature signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under the Indenture.

(e) The Trustee shall authenticate and make available for delivery Securities for original issue upon receipt of a written order or orders of the Company signed by an Officer of the Company (a “Company Order”). The Company Order shall specify the amount of Securities to be authenticated, whether such securities will be represented by a Global Security or Certificated Securities and the date on which each original issue of Securities is to be authenticated.

(f) The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple thereof.

Section 2.03 Registrar, Paying Agent and Conversion Agent.

(a) The Company shall maintain one or more offices or agencies where Securities may be presented for registration of transfer or for exchange (each, a “Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a “Conversion Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. One of the Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their transfer and exchange.

(b) The Company shall enter into an appropriate agency agreement with any Agent not a party to the Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions of the Indenture that relate to such Agent. The Company shall notify the Trustee in writing of the name and address of any Agent not a party to the Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service of notices and demands, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Section 5.01 and Article IX hereof).

(c) The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities Custodian and Conversion Agent, and designates the Corporate Trust Office of the Trustee as the office where notices and demands to or upon the Company in respect of the Securities and the Indenture shall be served.

Section 2.04 Paying Agent To Hold Money In Trust.

Prior to 12:00 p.m. (noon), New York City time, on each due date of the payment of principal of, or interest on, any Securities, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal or interest so becoming due. Subject to Section 9.03 hereof, a Paying Agent shall hold in trust for the benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Securities, and shall notify the Trustee in writing of any failure by the Company (or any other obligor on the Securities) to make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 12:00 p.m. (noon), New York City time, on each due date of the principal of, or interest on, any Securities, segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money.

Section 2.05 Lists of Holders of Securities.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee at least five (5) Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders of Securities.

Section 2.06 Transfer And Exchange.

(a) Subject to compliance with any applicable additional requirements contained in Section 2.12 hereof, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and completed in a manner satisfactory to the Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.03 hereof, the Company shall execute and upon receipt of a Company Order the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant to Section 2.10, 4.02(e) or 10.05 hereof.

(b) Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or portions thereof in respect of which a

-13-

Fundamental Change Repurchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased).

(c) All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the same benefits under the Indenture, as the Securities surrendered upon such transfer or exchange.

(d) Any Registrar appointed pursuant to Section 2.03 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities.

Section 2.07 Replacement Securities.

(a) If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them harmless, then, in the absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon delivery of a Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

(b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article III, or converted pursuant to Article IV, the Company in its discretion may, instead of issuing a new Security, pay, purchase or convert such Security, as the case may be.

(c) Upon the issuance of any new Securities under this Section 2.07, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith.

(d) Every new Security issued pursuant to this Section 2.07 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of the Indenture equally and proportionately with any and all other Securities duly issued hereunder.

(e) The provisions of this Section 2.07 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.08 Outstanding Securities.

(a) Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those purchased pursuant to Article III hereof, those

-14-

converted pursuant to Article IV hereof, those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those described in this Section 2.08 as not outstanding.

(b) If a Security is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser.

(c) If a Paying Agent (other than the Company or an Affiliate of the Company) holds in respect of the outstanding securities on a Fundamental Change Repurchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and accrued interest on Securities (or portions thereof) payable on that date, then on and after such Fundamental Change Repurchase Date or the Final Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding and cash interest on them shall cease to accrue.

(d) Subject to the restrictions contained in Section 2.09 hereof, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

Section 2.09 Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any notice, direction, waiver or consent, securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee with responsibility for the Indenture actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the Securities or any Affiliate of the Company or of such other obligor. Notwithstanding anything to the contrary in the TIA and to the maximum extent permitted by the TIA (it being understood that the provisions of Section 316(a) of the TIA are hereby expressly excluded to the extent inconsistent with this sentence), for purposes of this Section 2.09, no Holder shall be deemed to be an Affiliate of the Company solely as a result of such Holder’s ownership of the Securities or shares of Common Stock issued or issuable upon conversion of the Securities.

Section 2.10 Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities.

-15-

Section 2.11 Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer, exchange, purchase, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of the cancelled Securities in accordance with its customary procedures or deliver the canceled Securities to the Company. All Securities which are purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article III hereof shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities.

Section 2.12 Additional Transfer And Exchange Requirements.

(a) A Global Security may not be transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under the Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of the Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12.

(b) Whenever any Security other than a Global Security is presented or surrendered for registration of transfer or in exchange for a Security registered in a name other than that of the Holder, such Security must be accompanied by a certificate in substantially the form set forth in Exhibit A, dated the date of such surrender and signed by the Holder of such Security. The Registrar shall not be required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate.

As used in this Section 2.12(b), the term “transfer” encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security.

(1) Each Global Security authenticated under the Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for purposes of the Indenture.

(2) Notwithstanding any other provisions of the Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered, and no transfer of a Global Security in whole or in part shall be registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or

-16-

unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days after receiving such notice or becoming aware that the Depositary has ceased to be a “clearing agency,” or (B) an Event of Default has occurred and is continuing with respect to the Securities and the Depositary requests the issuance of Certificated Securities. Any Global Security exchanged pursuant to subclause (A) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to subclause (B) above may be exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided further that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security.

(3) Securities issued in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legend provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(4) Subject to clause (6) of this Section 2.12(c), the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Securities.

(5) In the event of the occurrence of any of the events specified in clause (2) of this Section 2.12(c), the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons.

(6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under the Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing

-17-

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

(7) At such time as all interests in a Global Security have been converted, cancelled or exchanged for Securities in certificated form, such Global Security shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Securities Custodian, subject to Section 2.11 hereof. At any time prior to such cancellation, if any interest in a Global Security is converted, canceled or exchanged for Securities in certificated form, the principal amount of such Global Security shall, in accordance with the standing procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced, and an endorsement shall be made on such Global Security, by the Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such reduction.

Section 2.13 CUSIP Numbers.

The Company in issuing the Securities may use a “CUSIP” number (if then generally in use), and, if so, the Trustee shall use the “CUSIP” number in notices of purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such number either as printed on the Securities or as contained in any notice of a purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any defect in or omission of such number. The Company will promptly notify the Trustee in writing of any change in the “CUSIP” number.

Section 2.14 No Additional Amounts.

Section 1004 of the Base Indenture shall not apply to the Securities.

ARTICLE III

REDEMPTION AND PURCHASE

Section 3.01 No Optional Redemption; No Sinking Fund.

Prior to the Final Maturity Date, the Securities shall not be redeemable at the option of the Company. The Securities shall not have the benefit of a sinking fund.

Section 3.02 Repurchase Of Securities At Option Of The Holder Upon a Fundamental Change.

(a) If a Fundamental Change occurs prior to the Final Maturity Date (or an event that would have been a Change of Control but for the existence of the Change of Control Exception), each Holder of a Security shall have the right, at the option of the Holder, provided that no Default or Event of Default has occurred and is continuing (other than a Default in the payment of the Fundamental Change Repurchase Price), to require the Company to repurchase for cash all or any portion of the Securities of such Holder equal to $1,000 principal amount (or an integral multiple thereof) at the Fundamental Change Repurchase Price, on the date that is not less than 30 days nor more than 45 days after the date of the Fundamental Change Company Notice pursuant to subsection 3.02(b) hereof (the “Fundamental Change Repurchase Date”).

(b) On or before the 30th day after the occurrence of a Fundamental Change (or an event that would have been a Change of Control but for the existence of the Change of Control Exemption), the Company shall mail a written notice of the Fundamental Change and of the resulting repurchase right to the Trustee, Paying Agent and to each Holder (and to beneficial owners to the extent and in the manner required by applicable law) (the “Fundamental Change Company Notice”). The Fundamental Change Company Notice shall include the form of a Fundamental Change Repurchase Notice to be completed by the Holder and shall state:

(1) the events causing such Fundamental Change;

(2) the date of such Fundamental Change;

(3) the last date by which the Fundamental Change Repurchase Notice must be delivered to elect the repurchase option pursuant to this Section 3.02;

(4) the Fundamental Change Repurchase Date;

(8) the then effective Conversion Rate and any adjustments to the Conversion Rate resulting from such Fundamental Change;

(9) the procedures that the Holder must follow to exercise rights under Article IV hereof and that Securities as to which a Fundamental Change Repurchase Notice has been given may be converted into Common Stock pursuant to Article IV of this Supplemental Indenture only to the extent that the Fundamental Change Repurchase Notice has been withdrawn in accordance with the terms of this Supplemental Indenture;

-19-

(10) the procedures that the Holder must follow to exercise rights under this Section 3.02;

(11) the procedures for withdrawing a Fundamental Change Repurchase Notice;

(12) that, unless the Company fails to pay such Fundamental Change Repurchase Price, Securities covered by any Fundamental Change Repurchase Notice will cease to be outstanding and interest will cease to accrue on and after the Fundamental Change Repurchase Date; and

(13) the CUSIP number of the Securities, provided that if such notice is provided by the Trustee, no representation is made as to the correctness or accuracy of such CUSIP number.

At the Company’s written request, the Trustee shall give such Fundamental Change Company Notice in the Company’s name and at the Company’s expense; provided, that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company and submitted to the Trustee along with an Officers’ Certificate and written request within 20 days after the occurrence of a Fundamental Change. If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Securities.

(c) A Holder may exercise its rights specified in Section 3.02(a) hereof upon delivery of a written notice (which shall be in substantially the form attached as Exhibit A under the heading “Fundamental Change Repurchase Notice” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change Repurchase Notice”) to the Company or any Paying Agent at any time prior to the close of business on the Business Day next preceding the Fundamental Change Repurchase Date, subject to extension to comply with applicable law.

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

(2) The delivery of a Security for which a Fundamental Change Repurchase Notice has been timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change Repurchase Date (together with all necessary endorsements) at the office of such Paying Agent

-20-

shall be a condition to the receipt by the Holder of the Fundamental Change Repurchase Price therefor.

(3) The Company shall only be obliged to purchase, pursuant to this Section 3.02, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000 (provisions of this Supplemental Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security).

(5) A Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Repurchase Notice or written withdrawal thereof.

(6) Anything herein to the contrary notwithstanding, in the case of Global Securities, any Fundamental Change Repurchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time.

Section 3.03 Effect Of Fundamental Change Repurchase Notice.

(a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Repurchase Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change Repurchase Notice was given shall (unless such Fundamental Change Repurchase Notice is withdrawn as specified in Section 3.03(b) hereof) thereafter be entitled to receive the Fundamental Change Repurchase Price with respect to such Security, subject to the occurrence of the Fundamental Change Effective Date. Such Fundamental Change Repurchase Price shall be paid to such Holder promptly following the later of (1) the Fundamental Change Repurchase Date (provided that the conditions in Section 3.02 hereof have been satisfied) and (2) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.02(c) hereof. Securities in respect of which a Fundamental Change Repurchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock pursuant to Article IV hereof on or after the date of the delivery of such Fundamental Change Repurchase Notice unless such Fundamental Change Repurchase Notice has first been validly withdrawn in accordance with Section 3.03(b) hereof with respect to the Securities to be converted.

(b) A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice (which may be delivered by mail, overnight courier, hand delivery, facsimile

-21-

transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately prior to the Fundamental Change Repurchase Date, specifying (1) the principal amount of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted, (2) if certificated Securities have been issued, the certificate number of the Security being withdrawn in whole or in withdrawable part (or if the Securities are not certificated, such written notice must comply with the procedures of the Depositary) and (3) the portion, if any, of the principal amount of the Security that will remain subject to the Fundamental Change Repurchase Notice, which portion must be a principal amount of $1,000 or an integral multiple thereof.

Section 3.04 Deposit of Fundamental Change Repurchase Price.

(a) On or before 12:00 p.m.(noon) New York City time on the Business Day following the applicable Fundamental Change Repurchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04 hereof) an amount of money (in immediately available funds if deposited on or after such Fundamental Change Repurchase Date), sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Securities or portions thereof that are to be purchased as of such Fundamental Change Repurchase Date.

(b) If a Paying Agent or the Trustee holds, in accordance with the terms hereof, money sufficient to pay the Fundamental Change Repurchase Price of any security for which a Fundamental Change Repurchase Notice has been tendered and not withdrawn in accordance with this Supplemental Indenture then, on the Business Day following the applicable Fundamental Change Repurchase Date, such Security will cease to be outstanding, whether or not the Security is delivered to the Paying Agent or the Trustee, and interest shall cease to accrue, and the rights of the Holder in respect of the Security shall terminate (other than the right to receive the Fundamental Change Repurchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities repurchased on or as soon as practicable after the Fundamental Change Repurchase Date.

(c) The Paying Agent will promptly return to the respective Holders thereof any Securities with respect to which a Fundamental Change Repurchase Notice has been withdrawn in compliance with this Supplemental Indenture.

(d) If a Fundamental Change Repurchase Date falls after a Regular Record Date and on or before the related Interest Payment Date, then interest on the Securities payable on such Fundamental Change Repurchase Date will be payable to the Holders in whose names the Securities are registered at the close of business on such Regular Record Date.

Section 3.05 Repayment To The Company.

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.04 hereof exceeds the aggregate Fundamental Change Repurchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Repurchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company.

Section 3.06 Compliance With Securities Laws Upon Purchase of Securities.

In connection with any offer to purchase of Securities under Section 3.02 hereof, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule) and any other tender offer rules, if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the Company under Sections 3.02 through 3.05 hereof to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would result in a conflict with any of the terms hereof, this Supplemental Indenture is hereby modified to the extent required for the Company to comply with such laws, rules and regulations, and the Company shall give prompt written notice to the Trustee of such modifications.

The Initial Purchasers and the Permitted Assignees (as defined in the Securities Purchase Agreement) have the right, at their option, to require the Company to repurchase for cash Securities with an aggregate principal amount of up to $7.5 million, to the extent and as more fully provided in Section 1(e) the Securities Purchase Agreement (the “Put Right”). The rights and obligations of the Company and the Initial Purchasers and the Permitted Assignees relating to the Put Right shall be governed by the Securities Purchase Agreement and not the Indenture unless otherwise specifically provided for in this Supplemental Indenture. Any Securities purchased by the Company pursuant to the Put Right shall be surrendered to the Trustee for cancellation.

ARTICLE IV

CONVERSION

Section 4.01 Conversion Privilege And Conversion Rate.

(a) Upon compliance with the provisions of this Article IV, at the option of the Holder thereof, any Security or portion thereof that is an integral multiple of $1,000 principal amount may be converted into fully paid and nonassessable shares (calculated as to each conversion to the nearest 1/100th of a share) of Common Stock at any time prior to the close of business on the Business Day immediately preceding the Final Maturity Date, unless previously purchased by the Company at the Holder’s option, at the Conversion Rate in effect at such time, determined as hereinafter provided and subject to the adjustments described below. Upon conversion of a Security, the Holder of such Security shall receive a number of shares of Common Stock equal to the product of (i) the number obtained by dividing the principal amount of the Security converted by $1,000 and (ii) the Conversion Rate in effect on the applicable Conversion Date; provided, however, that in lieu of any fractional share of Common Stock, the Company shall deliver an amount of cash equal to the product of (i) such fraction of a share and (ii) the Closing Price of the Common Stock on the applicable Conversion Date (or, if the applicable Conversion Date is not a Trading Day, the Trading Day immediately preceding such Conversion Date). The Company shall deliver the consideration due with respect to the conversion of any Security as soon as practicable after the applicable Conversion Date, but in no event later than three Business Days after the applicable Conversion Date.

(b) The conversion rights pursuant to this Article IV shall commence on the initial issuance date of the Securities and expire at the close of business on the Business Day immediately preceding the Final Maturity Date and shall be exercisable at any time, subject, in the case of conversion of any Global Security, to any Applicable Procedures. If a Security is submitted or presented for purchase pursuant to Article III hereof, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date for such Security (unless the Company shall fail to make the Fundamental Change Repurchase Price payment when due in accordance with Article III hereof, in which case the conversion right shall terminate at the close of business on the date such failure is cured and such Security is purchased). Securities in respect of which a Fundamental Change Repurchase Notice has been delivered may not be surrendered for conversion pursuant to this Article IV prior to a valid withdrawal of such Fundamental Change Repurchase Notice in accordance with the provisions of Article III hereof.

(c) Provisions of this Supplemental Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security.

(d) A Holder of Securities is not entitled to any rights of a holder of Common Stock until such Holder has converted its Securities into Common Stock.

(e) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(f) and Section 4.06 hereof.

-24-

(f) If prior to the Final Maturity Date, there shall have occurred a Fundamental Change (a “Make-Whole Fundamental Change”), the Company shall pay a “Make-Whole Premium” to the Holders of the Securities who convert their Securities from time to time during the period beginning on the Fundamental Change Effective Date and ending at the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date by increasing the Conversion Rate for such Securities. The number of additional shares of Common Stock per $1,000 principal amount of Securities constituting the Make-Whole Premium shall be determined by the Company by reference to the table below, based on the Fundamental Change Effective Date and the Stock Price of such Fundamental Change; provided that if the Stock Price or Fundamental Change Effective Date are not set forth on the table: (i) if the actual Stock Price on the Fundamental Change Effective Date is between two Stock Prices on the table or the actual Fundamental Change Effective Date is between two Fundamental Change Effective Dates on the table, the Make-Whole Premium will be determined by a straight-line interpolation between the Make-Whole Premiums set forth for the two Stock Prices and the two Fundamental Change Effective Dates on the table based on a 365-day year, as applicable, (ii) if the Stock Price on the Fundamental Change Effective Date exceeds $12.00 per share, subject to adjustment as set forth herein, no Make-Whole Premium will be paid, and (iii) if the Stock Price on the Fundamental Change Effective Date is less than $3.00 per share, subject to adjustment as set forth herein, no Make-Whole Premium will be paid. If Holders of the Common Stock receive only cash in the Fundamental Change, the Stock Price shall be the cash amount paid per share of the Common Stock in connection with the Fundamental Change. Otherwise, the Stock Price shall be equal to the average Closing Prices of the Common Stock for each of the 10 Trading Days immediately preceding, but not including, the applicable Fundamental Change Effective Date.

The Stock Prices set forth in the first column of the table above will be adjusted as of any date on which the Conversion Rate of the Securities is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of additional shares set forth in the table above will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06 hereof, other than as a result of an adjustment of the Conversion Rate by adding the Make-Whole Premium as described above.

Notwithstanding the foregoing paragraph, in no event will the total number of shares of Common Stock issuable upon conversion of a Security exceed 266.6667 per $1,000 principal amount, other than on account of proportional adjustments to the Conversion Rate in the manner set forth in clauses (1) and (2) of Section 4.06(a) hereof, unless the Company obtains shareholder approval of the increase in the Conversion Rate; provided, however, that the Company shall not undertake a Make-Whole Fundamental Change without first obtaining shareholder approval for the increase in the applicable Conversion Rate provided for in the table above.

The additional shares of Common Stock delivered to satisfy the Company’s obligations to Holders that convert their Securities in connection with a Make-Whole Fundamental Change and cash in lieu of fractional shares will be delivered by the Company upon the later of the settlement date for the conversion and promptly following the Fundamental Change Effective Date or the effective date of such other event.

Promptly upon the occurrence of any Make-Whole Fundamental Change, the Company shall deliver notice to each Holder and the Trustee, which notice will state that a Make-Whole Fundamental Change has occurred and include the Make-Whole Premium, if any. Simultaneously with delivering such notice, the Company shall publish the information contained in such notice on its website.

(g) By delivering the number of shares of Common Stock issuable on conversion and cash in lieu of fractional shares to the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the Securities so converted and, except as otherwise provided in Section 4.02(c) hereof, its obligation to pay accrued and unpaid interest attributable to the period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than cancelled, extinguished or forfeited).

(h) Notwithstanding any other provision of the Indenture to the contrary, during any period of time in which a person’s Beneficial Ownership (as defined below) of Common Stock is less than 5%, such person shall not have the right to convert all or any portion of any Security into shares of Common Stock to the extent that upon and after giving effect to such conversion, such person (together with such person’s Affiliates and any other persons or entities whose Beneficial Ownership of Common Stock would be aggregated with such person’s for purposes of Section 13(d) of the Exchange Act (the “Affiliated Parties”) (including shares held by any “group” of which such person or any of its Affiliated Parties is a member) would have Beneficial Ownership of more than 4.99% of the total number of shares of Common Stock then issued and outstanding; provided, that, such person may, from time to time, at its option and

-26-

upon not less than sixty-one (61) days’ prior notice to the Company, elect to increase such limitation to any other percentage not in excess of 9.99% of the number of outstanding shares of Common Stock then outstanding. Any such increase will not be effective until the 61^st day after such notice is delivered to the Company. The Company hereby covenants and agrees not to adopt any shareholder rights plan or take any other action which would have the effect of restricting or adversely affecting a person’s election to change such percentage limitation hereunder.

(i) For purposes of Sections 4.01(h) above, “Beneficial Ownership” shall mean the number of shares of Common Stock beneficially owned by a person and its Affiliated Parties (and any other persons or entities acting as a “group” together with a person or any of such Holder’s Affiliated Parties) and shall include the number of shares of Common Stock issuable upon conversion of the Securities with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) conversion of the remaining, unconverted portion of the Securities beneficially owned by such person or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such person or any of such person’s Affiliated Parties) and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company exercisable for or convertible into Common Stock that are subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such person or any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such person or any of such person’s Affiliated Parties). Except as set forth in the preceding sentence, for purposes of Section 4.01(h) hereof, Beneficial Ownership shall be calculated (and, for such purpose, whether any person or entity forms a “group” with any person or such person’s Affiliated Parties will be determined) in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (or, to the extent that, as a result of a change in law, regulation or interpretation after the date hereof, the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher Beneficial Ownership for any such party, then such Beneficial Ownership will be calculated in accordance with Section 16 of the Exchange Act and the rules and regulations thereunder), it being acknowledged by each person that the Company is not representing to any person that such calculation is in compliance with Section 13(d) of the Exchange Act and each person is solely responsible for any schedules required to be filed in accordance therewith. To the extent that an ownership limitation contained in Section 4.01(h) hereof applies, the determination of whether the Securities owned by a person are convertible (in relation to other securities owned by such person together with its Affiliated Parties (and any other persons or entities acting as a “group” together with such person or any of such person’s Affiliated Parties)) and of which portion of the Securities owned by such person is convertible shall be in the sole discretion of such person, and the submission of a conversion notice to the Conversion Agent (pursuant to Section 4.02 hereof) shall be deemed to be such person’s determination of whether the Securities owned by such person are convertible (in relation to other securities owned by such person together with any of its Affiliated Parties (and any other persons or entities acting as a “group” together with such person or any of such person’s Affiliated Parties)) and of which portion of such Securities are convertible, in each case subject to the then applicable ownership limitation (as determined in accordance with Section 4.01(h) hereof), and neither the Company nor the Conversion Agent shall have any obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any “group” status as contemplated above shall be determined in accordance

-27-

with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. To ensure compliance with this restriction, the person will be deemed to represent to the Company each time it delivers a conversion notice (pursuant to Section 4.02 hereof) that such conversion notice has not violated the restrictions set forth in Section 4.01(h) hereof.

(j) For the avoidance of doubt, if a person purports to convert any Security into shares of Common Stock hereunder and any delivery otherwise owed to such person hereunder is not made, in whole or in part, as a result of the then applicable ownership limitation (as determined in accordance with Section 4.01(h) hereof), then the person’s rights under the relevant Security pursuant to which such delivery was not made will not be extinguished and, instead such Security will be deemed to have never been converted by such person.

Section 4.02 Conversion Procedure.

(a) To convert a Security, a Holder must (1) complete and manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (2) surrender the Security to a Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, (4) pay all transfer or similar taxes, if required pursuant to Section 4.04 hereof, and (5) pay funds equal to the interest payable on the Interest Payment Date immediately following the Conversion Date, if required pursuant to Section 4.02(c) hereof. The date on which the Holder satisfies all of those requirements is the “Conversion Date.” Upon the conversion of a Security, the Company will deliver the shares of Common Stock and cash in lieu of fractional shares as promptly as practicable after the Conversion Date, but in no event later than three Business Days after the Conversion Date. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance with the Applicable Procedures as in effect from time to time.

(b) The person in whose name the shares of Common Stock are issuable upon conversion shall be deemed to be a holder of record of such Common Stock on the close of business on the Conversion Date; provided, however, that no surrender of a Security 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; provided further that such conversion shall be at the applicable Conversion Rate as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. Except as set forth in this Supplemental 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 Security prior to the issuance of such shares.

(c) Holders of Securities surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date will receive the semi-annual interest payable on such Securities on the corresponding Interest Payment Date notwithstanding the

-28-

conversion. Upon surrender of any such Securities for conversion, such Securities shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date, except to the extent of any overdue interest that is due at the time of conversion, unless (i) such Securities are converted after the close of business on the Regular Record Date immediately preceding the Final Maturity Date, or (ii) if the Company has specified a Fundamental Change Repurchase Date that is after such Regular Record Date and on or prior to such Interest Payment Date and the Holder surrenders the Securities for conversion after the close of business on such Regular Record Date and prior to the open of business on such Fundamental Change Repurchase Date, in which cases no such payment will be required. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be made for accrued interest on a converted Security.

(d) Subject to Section 4.02(c) hereof, nothing in this Section shall affect the right of a Holder in whose name any Security is registered at the close of business on a Regular Record Date to receive the interest payable on such Security on the related Interest Payment Date in accordance with the terms of this Supplemental Indenture and the Securities. If a Holder converts more than one Security 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 4.03 hereof) shall be based on the aggregate principal amount of all Securities so converted.

(e) In the case of any Security which is converted in part only, upon such conversion the Company shall execute and the Trustee, upon receipt of a Company Order and all Opinions of Counsel and Officers’ Certificates as are required to be delivered to the Trustee pursuant to the terms of this Supplemental Indenture, shall authenticate and deliver to the Holder thereof, without service charge, a new Security or Securities of authorized denominations in an aggregate principal amount equal to, and in exchange for, the unconverted portion of the principal amount of such Security. A Security 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 Security to remain outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof.

Section 4.03 Fractional Shares.

The Company will not issue fractional shares of Common Stock upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. In lieu of any fractional shares, the Company will pay an amount in cash equal to the product of (i) such fraction of a share and (ii) the Closing Price of the Common Stock on the applicable Conversion Date (or, if the applicable Conversion Date is not a Trading Day, the Trading Day immediately preceding such Conversion Date).

Section 4.04 Taxes On Conversion.

If a Holder converts a Security, the Company shall pay any transfer, stamp or similar taxes or duties related to the issue or delivery of shares of Common Stock upon such conversion,

-29-

unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay such tax. The Conversion Agent may refuse to deliver the certificate representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due in accordance with the immediately preceding sentence. Nothing herein shall preclude any tax withholding required by law or regulation.

Section 4.05 Company To Provide Stock.

(a) The Company shall, prior to issuance of any Securities 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 Securities into shares of Common Stock.

(b) All shares of Common Stock delivered upon conversion of the Securities 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.

(c) The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities.

Section 4.06 Adjustment Of Conversion Rate.

(a) The Conversion Rate shall be adjusted from time to time by the Company as follows:

(1) If the Company shall pay a dividend or make a distribution to all holders of outstanding Common Stock in shares of Common Stock, the Conversion Rate in effect immediately prior to the record date for the determination of shareholders entitled to receive such dividend or other distribution shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator of shall be the sum of the number of shares of Common Stock outstanding at the close of business on such record date plus the total number of shares of Common Stock constituting such dividend or other distribution and of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date. Such adjustment shall be made successively whenever any such dividend or distribution is made and shall become effective immediately after such record date. For the purpose of this clause (1), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company will not pay any dividend or make any distribution on Common Stock held in the treasury of the Company. If any dividend or distribution of the type described in this clause is declared but not so paid or made, the Conversion Rate

-30-

shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(2) If the Company shall subdivide its outstanding Common Stock into a greater number of shares, or combine its outstanding Common Stock into a smaller number of shares, the Conversion Rate in effect immediately prior to the day upon which such subdivision or combination becomes effective shall be, in the case of a subdivision of Common Stock, proportionately increased and, in the case of a combination of Common Stock, proportionately reduced. Such adjustment shall be made successively whenever any such subdivision or combination of the Common Stock occurs and shall become effective immediately after the date upon which such subdivision or combination becomes effective.

(3) If the Company shall issue rights or warrants to all holders of its outstanding Common Stock entitling them (for a period expiring within 45 days after such issuance) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or having a conversion price per share) less than the Current Market Price per share of Common Stock (as determined in accordance with clause (9) of this Section 4.06(a)) on the record date for the determination of shareholders entitled to receive such rights or warrants, the Conversion Rate in effect immediately prior thereto shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the number of additional shares of Common Stock that such rights or warrants entitle holders thereof to subscribe for or purchase (or into which such convertible securities are convertible) and of which the denominator shall be the number of shares of Common Stock outstanding at the close of business on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered for subscription or purchase (or the aggregate conversion price of the convertible securities so offered for subscription or purchase, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) would purchase at the Current Market Price per share of Common Stock on such record date. Such adjustment shall be made successively whenever any such rights or warrants (or convertible securities) are issued, and shall become effective immediately after such record date. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered after the expiration of such rights or warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock (or securities convertible into Common Stock) actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion

-31-

Rate that would then be in effect if the record date for the determination of shareholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the shareholders to subscribe for or purchase shares of Common Stock at a price less than the Current Market Price per share of Common Stock and in determining the aggregate offering price of the total number of shares of Common Stock so offered, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors.

(4) If the Company shall make a dividend or other distribution to all holders of its Common Stock of Capital Stock, other than Common Stock, or evidences of indebtedness or other assets of the Company (excluding (x) any issuance of rights or warrants for which an adjustment was made pursuant to Section 4.06(a)(3) hereof, (y) dividends or distributions in connection with a reclassification, change, consolidation, merger, combination, liquidation, dissolution, winding up, sale or conveyance resulting in a change in the conversion consideration, or pursuant to any shareholder rights plan or (z) any dividend or distribution paid exclusively in cash for which an adjustment was made pursuant to Section 4.06(a)(6) hereof) (the “Distributed Securities”), then in each such case (unless the Company distributes such Distributed Securities for distribution to the Holders of Securities on such dividend or distribution date as if each Holder had converted such Security into Common Stock immediately prior to the record date with respect to such distribution) the Conversion Rate in effect immediately prior to the record date fixed for the determination of shareholders entitled to receive such dividend or distribution shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to such record date by a fraction of which the numerator shall be the Current Market Price per share of the Common Stock on such record date and of which the denominator shall be Current Market Price per share on such record date less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) on such record date of the portion of the Distributed Securities so distributed applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on such record date). Such adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of shareholders entitled to receive such distribution. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

If the fair market value (as so determined) of the portion of the Distributed Securities so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made

-32-

so that each holder of a Security shall have the right to receive upon conversion the amount of Distributed Securities so distributed that such Holder would have received had such Holder converted each Security on such record date. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 4.06(a)(4) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the Current Market Price of the Common Stock.

Notwithstanding the foregoing, if the securities distributed by the Company to all holders of its Common Stock consist of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company (the “Spinoff Securities”), the Conversion Rate shall be adjusted, unless the Company makes an equivalent distribution to the Holders of the Securities, so that the same shall be equal to the rate determined by multiplying the applicable Conversion Rate in effect on and after the record date fixed for the determination of shareholders entitled to receive such distribution by a fraction, the numerator of which shall be the sum of (A) the average Closing Price of one share of Common Stock over the ten consecutive Trading Day period (the “Spinoff Valuation Period”) commencing on and including the fifth Trading Day after the date on which ex-dividend trading commences for such distribution on the NASDAQ Global Select Market or such other U.S. national or regional exchange or market on which the Common Stock is then listed or quoted and (B) the average of the Closing Prices over the Spinoff Valuation Period of the Spinoff Securities multiplied by the number of Spinoff Securities distributed in respect of one share of Common Stock and the denominator of which shall be the average Closing Price of one share of Common Stock over the Spinoff Valuation Period, such adjustment to become effective immediately prior to the opening of business on the fifteenth Trading Day after the date on which ex-dividend trading commences; provided, however, that the Company may in lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such Holder of Securities would have received if such Securities had been converted on the record date with respect to such distribution.

(5) With respect to any rights, rights certificates or warrants (the “Rights”) that may be issued or distributed pursuant to any rights plan (including any rights plan that the Company implements after the date of this Supplemental Indenture, a “Rights Plan”), in lieu of any adjustment required by any other provision of this Section 4.06, upon conversion of the Securities into Common Stock, to the extent that such Rights Plan is in effect upon such conversion, the Holders of Securities will receive, with respect to the shares of Common Stock issued upon conversion, the Rights described therein (whether or not the Rights have separated from the Common Stock at the time of conversion), subject to the limitations set forth in and in accordance with any such Rights Plan; provided that if, at the time of conversion, however, the Rights have separated from the shares of Common Stock in accordance with the provisions of the Rights Plan so that

-33-

Holders would not be entitled to receive any rights in respect of the shares of Common Stock issuable upon conversion of the Securities as a result of the timing of the Conversion Date, the Conversion Rate will be adjusted as if the Company distributed to all holders of Common Stock Distributed Securities as provided in the first paragraph of clause (4) of this Section 4.06(a), subject to appropriate readjustment in the event of the expiration, termination, repurchase or redemption of the Rights. Any distribution of rights, rights certificates or warrants pursuant to a Rights Plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights, rights certificates or warrants pursuant to this Section 4.06(a). Other than as specified in this clause (5) of this Section 4.06(a), there will not be any adjustment to the Conversion Rate as the result of the issuance of any Rights, the distribution of separate certificates representing such Rights, the exercise or redemption of such Rights in accordance with any Rights Plan or the termination or invalidation of any Rights.

(6) If the Company shall, by dividend or otherwise, at any time distribute (a “Triggering Distribution”) to all holders of its Common Stock a payment consisting exclusively of cash (excluding any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company, whether voluntary or involuntary) the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying such Conversion Rate in effect immediately prior to the close of business on the record date for such Triggering Distribution (a “Determination Date”) by a fraction of which the numerator shall be such Current Market Price per share of the Common Stock on the Determination Date and the denominator of which shall be the Current Market Price per share of the Common Stock on the Determination Date less the amount of such cash dividend or distribution applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on the Determination Date), such increase to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. If the amount of cash dividend or distribution applicable to one share of Common Stock is equal to or greater than the Current Market Price per share of the Common Stock on the Determination Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder of a Security shall have the right to receive upon conversion the amount of cash so distributed that such Holder would have received had such Holder converted each Security on such Determination Date. In the event that such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect if such divided or distribution had not been declared.

(7) If any tender offer made by the Company or any of its Subsidiaries for all or any portion of Common Stock shall expire, then, if the tender offer shall require the payment to shareholders of consideration per share of Common Stock having a fair market value (determined as provided below) that exceeds the Closing Price per share of Common Stock on the Trading Day next succeeding

-34-

the last date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter sometimes called the “Expiration Time”), the Conversion Rate shall be increased so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Expiration Date by a fraction of which the numerator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined in good faith by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) payable to shareholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (B) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Closing Price per share of Common Stock on the Trading Day next succeeding the Expiration Date and the denominator of which shall be the product of the number of shares of Common Stock outstanding (including Purchased Shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Closing Price per share of the Common Stock on the Trading Day next succeeding the Expiration Date, such increase to become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would have been in effect based upon the number of shares actually purchased, if any. If the application of this clause (7) of Section 4.06(a) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this clause (7).

(8) For purposes of this Section 4.06, the term “tender offer” shall mean and include both tender offers and exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the acquisition of shares pursuant to exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers.

(9) For purposes of any computation under this Section 4.06, “Current Market Price” shall mean the average of the daily Closing Prices per share of Common Stock for each of the ten consecutive Trading Days immediately prior to the date in question; provided, however, that if

(A) the “ex” date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that

-35-

requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) hereof occurs during such ten consecutive Trading Days, the Closing Price for each Trading Day prior to the “ex” date for such other event shall be adjusted by dividing such Closing Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event;

(B) the “ex” date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a) (1), (2), (3), (4), (5), (6) or (7) hereof occurs on or after the “ex” date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event; and

(C) the “ex” date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to the immediately preceding clause (A) or (B) of this Section 4.06(a)(9), the Closing Price for each Trading Day on or after such “ex” date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined in good faith by the Board of Directors in a manner consistent with any determination of such value for purposes of Section 4.06(a)(4) or (7) hereof, whose determination shall be conclusive and set forth in a Board Resolution) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such “ex” date.

For purposes of any computation under Section 4.06(a)(7) hereof, if the “ex” date for any event (other than the tender offer that is the subject of the adjustment pursuant to Section 4.06(a)(7) hereof) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a)(1), (2), (3), (4), (5) or (6) hereof occurs on the date of the Expiration Time for the tender or exchange offer requiring such computation or on the Trading Day next following the Expiration Time, the Closing Price for each Trading Day on and after the “ex” date for such other event shall be adjusted by dividing such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this Section 4.09(a) the term “ex” date, when used:

(A) with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution;

-36-

(B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and

(C) with respect to any tender or exchange offer, means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer.

Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 4.06, such adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 4.06 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors.

(b) In any case in which this Section 4.06 shall require that an adjustment be made following a record date, a Determination Date or Expiration Date, as the case may be, established for the purposes specified in this Section 4.06, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.08 hereof) issuing to the Holder of any Security converted after such record date, Determination Date or Expiration Date the shares of Common Stock and other Capital Stock of the Company issuable upon such conversion over and above the shares of Common Stock and other Capital Stock of the Company (or other cash, property or securities, as applicable) issuable upon such conversion only on the basis of the Conversion Rate prior to adjustment; and, in lieu of any cash, property or securities the issuance of which is so deferred, the Company shall issue or cause its transfer agents to issue due bills or other appropriate evidence prepared by the Company of the right to receive such cash, property or securities. If any distribution in respect of which an adjustment to the Conversion Rate is required to be made as of the record date, Determination Date or Expiration Date therefore is not thereafter made or paid by the Company for any reason, the Conversion Rate shall be readjusted to the Conversion Rate which would then be in effect if such record date had not been fixed or such record date, Determination Date or Expiration Date had not occurred.

(c) For purposes of this Section 4.06, “record date” shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged or converted into any combination of cash, securities or other property, the date fixed for determination of shareholders entitled to receive such cash, security or other property (whether or not such date is fixed by the Board of Directors or by statute, contract or otherwise).

(d) If one or more event occurs requiring an adjustment be made to the Conversion Rate for a particular period, adjustments to the Conversion Rate shall be determined by the Company’s Board of Directors to reflect the combined impact of such Conversion Rate adjustment events, as set out in this Section 4.06, during such period.

-37-

Section 4.07 No Adjustment

(a) No adjustment in the Conversion Rate shall be required if Holders may participate in the transactions set forth in Section 4.06 above (to the same extent as if the Securities had been converted into Common Stock immediately prior to such transactions) without converting the Securities held by such Holders.

(b) 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 4.07(b) shall be carried forward and made, regardless of whether the aggregate adjustment is less than 1%, (i) on each anniversary of the Issue Date of the Securities and (ii) on the Conversion Date for any Securities. All calculations under this Article IV shall be made to the nearest cent or to the nearest one-ten thousandth of a share, as the case may be, with one half cent and 0.00005 of a share, respectively, being rounded upward.

(c) No adjustment in the Conversion Rate shall be required for issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock.

(d) To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash.

(e) Notwithstanding anything to the contrary provided in Section 4.06 hereof, in no event shall the Conversion Rate as adjusted in accordance with Section 4.06 hereof exceed 266.6667 per $1,000 principal amount, other than on account of proportional adjustments to the Conversion Rate in the manner set forth in clauses (1) and (2) of Section 4.06(a), unless the Company obtains shareholder approval of the increase in the Conversion Rate; provided, however, that the Company shall not undertake any action described in clauses (3), (4), (5), (6) or (7) of Section 4.06(a) above without first obtaining shareholder approval for the increase in the applicable Conversion Rate that would otherwise be required as a result of such action.

Section 4.08 Notice of Adjustment.

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

Section 4.09 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 10 days before such proposed effective date. Failure to

-38-

mail such notice or any defect therein shall not affect the validity of any transaction referred to in this Section 4.09.

Section 4.10 Effect of Recapitalization, Reclassification, Consolidation, Merger or Sale.

If any of following events occur (each, a “Business Combination”):

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

(2) a consolidation, merger or combination involving the Company,

(3) a sale, conveyance or lease to another corporation of all or substantially all of the property and assets of the Company, other than one or more of the Company’s subsidiaries, or

(4) any statutory share exchange,

in each case as a result of which holders of Common Stock are entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that the Holders of the Securities then outstanding will be entitled thereafter to convert such Securities 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 Business Combination had such Securities been converted into Common Stock immediately prior to such Business Combination, except that such Holders will not receive the Make-Whole Premium if such Holder does not convert its Securities “in connection with” the relevant Make-Whole Fundamental Change. A conversion of the Securities by a Holder will be deemed for these purposes to be “in connection with” a Make-Whole Fundamental Change if the notice of such conversion is provided in compliance with Section 4.02(a) hereof to the Conversion Agent on or subsequent to the Fundamental Change Effective Date but before the close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in such Business Combination, the Company shall make adequate provision whereby the Holders of the Securities shall have a reasonable opportunity to determine the form of consideration into which all of the Securities, treated as a single class, shall be convertible from and after the effective date of such Business Combination. Such determination shall be (i) based on the weighted average of elections made by Holders of the Securities who participate in such determination, (ii) subject to any limitations to which all of the holders of the Common Stock are subject, such as pro-rata reductions applicable to any portion of the consideration payable in such Business Combination and (iii) conducted in such a manner as to be completed by the date which is the earliest of (a) the deadline for elections to be made by shareholders of the Company, and (b) two Trading Days prior to the anticipated effective date of the Business Combination. The

-39-

Company shall provide notice of the opportunity to determine the form of such consideration, as well as notice of the determination made by Holders of the Securities (and the weighted average of elections), by posting such notice with DTC and providing a copy of such notice to the Trustee. In the event the effective date of the Business Combination is delayed beyond the initially anticipated effective date, Holders of the Securities shall be given the opportunity to make subsequent similar determinations in regard to such delayed effective date. The Company may not become a party to any such transaction unless its terms are consistent with this Section 4.10. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article IV. If, in the case of any such Business Combination, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such Business Combination, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article III hereof. Notwithstanding anything contained in this Section, and for the avoidance of doubt, this Section shall not affect the right of a Holder to convert its Securities into shares of Common Stock prior to the effective date of the Business Combination.

Section 4.11 Trustee’s Disclaimer.

(a) The Trustee shall have no duty to determine when an adjustment under this Article IV 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 Officers’ Certificate and Opinion of Counsel, including the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08 hereof. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article IV.

(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 4.10 hereof, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officers’ Certificate and Opinion of Counsel, with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 11.04 of this Supplemental Indenture.

Section 4.12 Voluntary Increase.

The Company from time to time may increase the Conversion Rate, to the extent permitted by law, by any amount for any period of time if the period is at least 20 Business Days, and the Company provides 15 days’ prior written notice to any increase in the Conversion Rate to the Trustee and Holders. The Company may also make such an increase to the Conversion Rate as the Board of Directors determines would avoid or diminish income tax to holders of shares of Common Stock in connection with a dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes.

COVENANTS

Section 5.01 Payment Of Securities.

The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this Supplemental Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 12:00 p.m. (noon), New York City time, on that date money, deposited by or on behalf of the Company sufficient to make the payment. Subject to Section 4.02 hereof, accrued and unpaid interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Principal, Fundamental Change Repurchase Price, and interest, in each case if payable, shall be considered paid on the applicable date due if on such date (or, in the case of Fundamental Change Repurchase Price, on the Business Day following the applicable Fundamental Change Repurchase Date) the Trustee or the Paying Agent holds, in accordance with the Indenture, money sufficient to pay all such amounts then due.

(b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained for that purpose at the Corporate Trust Office of the Trustee 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 at the option of the Company payment of interest may be made through the Paying Agent by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

Section 5.02 SEC and Other Reports.

The Company shall file all reports and other information and documents which it is required to file with the SEC pursuant to Section 13 or

-41-

15(d) of the Exchange Act, and within 15 days after it files them with the SEC, the Company shall file copies of all such reports, information and other documents with the Trustee; provided that any such reports, information and documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval (or ▇▇▇▇▇) system shall be deemed to be filed with the Trustee. The Company also shall comply with the provisions of TIA Section 314(a). If at any time the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company will make publicly available the information specified in Rule 144(c)(2) under the Securities Act on a quarterly basis.

(b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

Section 5.03 Compliance Certificates.

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 September 25, 2015), an Officers’ Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Supplemental Indenture and stating whether or not the signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of Default, the Officers’ Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of this Section 5.03, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Supplemental Indenture.

The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or accrued but unpaid interest, if any, on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Supplemental Indenture, and the Company (to the extent it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede

-42-

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 5.07 Maintenance of Office or Agency.

This Section 5.07 shall supersede Section 1002 of the Base Indenture and all references in the Base Indenture to Section 1002 thereof shall be deemed, for the purposes of the Securities, to be references to this Section 5.07. The Company will maintain an office or agency of the Trustee, Registrar and Paying Agent where Securities may be presented or surrendered for payment, where Securities may be surrendered for registration of transfer or purchase and where notices and demands to or upon the Company in respect of the Securities and the Indenture may be served. The Corporate Trust Office shall initially be one such office or agency for all of the aforesaid purposes. The Company shall give prompt written notice to the Trustee of the location, and of any change in the location, of any such office or agency (other than a change in the location of the office of the Trustee). 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, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02 hereof.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency.

Section 5.08 Portfolio Interest Exemption.

The Company agrees that payments of interest on Securities are eligible for the “portfolio interest” exemption from U.S. federal withholding tax under Sections 871(h) and 881(c) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), provided that the beneficial owner of such Securities provides the appropriate IRS Form(s) W-8 and that the beneficial owner is not a 10-percent shareholder of the Company (within the meaning of Section 871(h)(3)(B) of the Code), a controlled foreign corporation to which the Company is related, or a bank extending credit to the Company in the ordinary course of its trade or business.

Section 5.09 Reimbursement of Expenses.

The Company will reimburse the Initial Purchasers and the Permitted Assignees on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the Securities Purchase Agreement and this Supplemental Indenture including, without limitation, the purchase of the Securities, any exercise of the Put Right under Section 1(e) of the Securities Purchase Agreement and the enforcement of their rights and obligations hereunder and thereunder.

A notice given pursuant to this Section 7.01 shall be given by registered or certified mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under this Section 7.01 is cured, it ceases.

(c) The Company will deliver to the Trustee, within five Business Days after becoming aware of the occurrence of a Default or Event of Default, written notice thereof.

Section 7.02 Acceleration.

If an Event of Default (other than an Event of Default specified in clauses (7) or (8) of Section 7.01(a) hereof) occurs and is continuing with respect to the Company, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, through the date of declaration on all the Securities to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 7.01(a)(7) or (8) hereof occurs in respect of the Company and is continuing, the principal amount and accrued but unpaid interest, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Securities. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which have become due solely by such declaration of acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor

-47-

(b) 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. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by applicable law.

Section 7.04 Waiver Of Defaults And Events Of Default.

Subject to Sections 7.07 and 10.02 hereof, the Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except an uncured Default or Event of Default in the payment of the principal of, premium, if any, or any accrued but unpaid interest on any Security, an uncured failure by the Company to convert any Securities into Common Stock or any Default or Event of Default in respect of any provision of the Indenture or the Securities which, under Section 10.02 hereof, cannot be modified or amended without the consent of the Holder of each Security affected. When a Default or Event of Default is waived, it is cured and ceases.

Section 7.05 Control By Majority.

The Holders of a majority in aggregate principal amount of the Securities then outstanding may 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 it. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered security or indemnity satisfactory to it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 7.06 Limitations On Suits.

(a) A Holder may not pursue any remedy with respect to the Indenture or the Securities (except actions for payment of overdue principal, premium, if any, or interest or for the conversion of the Securities pursuant to Article IV hereof) unless:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default;

-48-

(2) the Holders of at least 25% in aggregate principal amount of the then outstanding Securities make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer to the Trustee security or indemnity to the Trustee against any loss, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Securities then outstanding.

(b) No Holder of a Security shall have any right under any provision of the Indenture or the Securities to affect, disturb, or prejudice the rights of another Holder of a Security or to obtain a preference or priority over another Holder of a Security.

Section 7.07 Rights Of Holders To Receive Payment And To Convert.

Notwithstanding any other provision of the Indenture, the right of any Holder of a Security to receive payment of the principal amount, Fundamental Change Repurchase Price, or Make-Whole Premium and interest, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and the Indenture, (whether upon repurchase or otherwise), and to convert such Security in accordance with Article IV hereof, 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 IV hereof, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder.

Section 7.08 Collection Suit By Trustee.

If an Event of Default described in clause (1) or (2) of Section 7.01(a) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount owing with respect to the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 7.09 Trustee May File Proofs Of Claim.

The Trustee may file such proofs of claim and 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 the Holders allowed in any judicial proceedings relative to the Company (or any other obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Receiver in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent

-49-

to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607 of the Base Indenture or otherwise owing to the Trustee under the Base Indenture or this Supplemental Indenture, and to the extent that such payment of the compensation, reasonable expenses, disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

This Section 7.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 7.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding.

1. INTEREST

Hutchinson Technology Incorporated, a Minnesota corporation (the “Company”, which term shall include any successor corporation under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 8.50% per annum. The Company shall pay interest semi-annually on April 30 and October 31 of each year (each an “Interest Payment Date”), commencing April 30, 2015. Each payment of interest will include interest accrued through the day before the relevant Interest Payment Date (or purchase date, as the case may be). Cash interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

No sinking fund is provided for the Securities.

2. METHOD OF PAYMENT

The Company shall pay interest on this Security (except defaulted interest) to the person who is the Holder of this Security at the close of business on April 15 or October 15, as the case may be (each, a “Regular Record Date”), next preceding the related Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. The Company may pay principal and interest in respect of any Certificated Security through the Paying Agent by check or wire payable in such money; provided, however, that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the Interest Payment Date. The Company may mail an interest check to the Holder’s registered address. Notwithstanding the foregoing, so long as this Security is registered in the name of a Depositary or its nominee, all payments hereon shall be made by wire transfer of immediately available funds to the account of the Depositary or its nominee.

Any wire transfer instructions received by the Trustee will remain in effect until revoked by the Holder.

Initially, U.S. Bank National Association (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent.

The Company or any of its Subsidiaries may, subject to certain limitations set forth in the Indenture, act as Paying Agent or Registrar.

At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for cash, subject to certain exceptions described in the Indenture, all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000) of the Securities held by such Holder on a date specified by the Company that is not less than 30 nor more than 45 days after the date of the Fundamental Change Company Notice, at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date. The Holder shall have the right to withdraw any Fundamental Change Repurchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000) at any time prior to the close of business on the Business Day next preceding the Fundamental Change Repurchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture.

Subject to and upon compliance with the provisions of the Indenture, a Holder may surrender for conversion any Security that is $1,000 principal amount or integral multiples thereof. Upon conversion of a Security, the Holder of such Security shall receive a number of shares of Common Stock equal to the product of (i) the number obtained by dividing the principal amount of the Security converted by $1,000 and (ii) the Conversion Rate in effect on the applicable Conversion Date; provided, however, that in lieu of any fractional share of Common Stock, the Company shall deliver an amount of cash equal to the product of (i) such fraction of a share and (ii) the Closing Price of the Common Stock on the applicable Conversion

A Holder may register the transfer of or exchange Securities in accordance with the Indenture.

11. PERSONS DEEMED OWNERS

The Holder of a Security may be treated as the owner of it for all purposes.

12. UNCLAIMED MONEY

If money for the payment of principal or interest remains unclaimed for two years, the Trustee and any Paying Agent will pay the money back to the Company at its written request, subject to applicable unclaimed property law and the provisions of the Indenture. After that, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates another person.

13. AMENDMENT, SUPPLEMENT AND WAIVER

Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Securities then outstanding, and an existing Default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or make any other change (other than a change affecting the rights of a Holder to convert any of the Securities) that does not adversely affect the rights of the Holders in any material respect.

14. SUCCESSOR ENTITY

When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor corporation (except in certain circumstances specified in the Indenture) shall be released from those obligations.

A-6

15. DEFAULTS AND REMEDIES

Under the Indenture, an Event of Default with respect to the Securities shall occur if:

(2) the Company shall fail to pay an installment of cash interest on any of the Securities, which failure continues for 30 days after the date when due; or

(7) the Company pursuant to or within the meaning of any Bankruptcy Law:

(A) commences as a debtor a voluntary case or proceeding; or

(B) consents to the entry of an order for relief against it in an involuntary case or proceeding or the commencement of any case against it; or

(D) makes a general assignment for the benefit of its creditors; or

(E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or

A-7

(F) consents to the filing of such a petition or the appointment of or taking possession by a Receiver; or

(8) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A) grants relief against the Company in an involuntary case or proceeding or adjudicates the Company insolvent or bankrupt;

(B) appoints a Receiver of the Company or for all or substantially all of the property of the Company; or

and in each case the order or decree remains unstayed and in effect for 60 consecutive days; or

(9) the Company shall fail to timely issue a Fundamental Change Company Notice in accordance with Section 3.02(b) of the Supplemental Indenture.

Notwithstanding the above, no Event of Default under clauses (4) or (5) above shall occur until the Trustee notifies the Company in writing, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within the time specified in clause (4) or (5), as applicable, after receipt of such notice.

If an Event of Default (other than an Event of Default specified in clauses (7) or (8) above) occurs and is continuing with respect to the Company, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare the principal amount and accrued and unpaid interest, if any, through the date of declaration on all the Securities to be immediately due and payable. Upon such a declaration, such principal amount and such accrued and unpaid interest, if any, shall be due and payable immediately. If an Event of Default specified in clauses (7) or (8) occurs in respect of the Company and is continuing, the principal amount and accrued but unpaid interest, if any, on all the Securities shall become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of Securities. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which have become due solely by such declaration of acceleration, have been cured or waived; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all payments due to the Trustee and any predecessor Trustee under the Indenture have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. Holders may not enforce the Indenture or the Securities

A-8

except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest) if and so long as it determines that withholding notice is in their interests. The Company is required to file periodic certificates with the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default.

16. TRUSTEE DEALINGS WITH THE COMPANY

U.S. Bank National Association, the initial Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or an Affiliate of the Company, and may otherwise deal with the Company or an Affiliate of the Company, as if it were not the Trustee.

17. NO RECOURSE AGAINST OTHERS

A director, officer, employee or shareholder, as such, of the Company shall not have any liability for any obligations of the Company under the Securities or the Indenture nor for any claim based on, in respect of or by reason of such obligations or their creation. The Holder of this Security by accepting this Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of this Security.
