ARTICLE 2 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 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. The Securities are being offered and sold by the Company pursuant to a Purchase Agreement dated April 4, 2007 (the "Purchase Agreement") between the Company and the Initial Purchaser. 10 (a) Restricted Global Securities. All of the Securities are initially being offered and sold to qualified institutional buyers as defined in Rule 144A (collectively, "QIBs" or individually, each a "QIB") in reliance upon a private placement exemption from registration under the Securities Act and shall be issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the purchasers of the securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company ("DTC", and such depositary, or any 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 the Restricted Global Securities 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 replacements, exchanges, purchases, redemptions, 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 this 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 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 legends 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 11 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 A 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 this Indenture is limited to $100,000,000 aggregate principal amount except as provided in Sections 2.06 and 2.07. (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 this Indenture. (e) The Trustee shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of up to $100,000,000 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, shall provide that all such securities will be represented by a Restricted Global Security and the date on which each original issue of Securities is to be authenticated. 12 (f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. (g) 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 this Indenture may be served. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. 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 this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service of notices and demands in any place required by this Indenture, 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 9). (c) The Company hereby initially designates the Trustee as Paying Agent, Registrar, Securities Custodian and Conversion Agent, and initially designates the Corporate Trust Office of the Trustee as an office or agency where notices and demands to or upon the Company in respect of the Securities and this 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 9.02, 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 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 13 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 on or 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, 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 the form of Security attached as Exhibit A hereto, 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, the Company shall execute and 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, 2.12(a), 3.06, 4.02(e) or 10.05. (b) Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of (1) any Securities for a period of 15 days next preceding mailing of a notice of Securities to be redeemed, or (2) any Securities or portions thereof in respect of which a Fundamental Change Purchase 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 this Indenture, as the Securities surrendered upon such transfer or exchange. 14 (d) Any Registrar appointed pursuant to Section 2.03 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. (e) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or other beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Section 2.07. Replacement Securities. (a) If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, and 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 its written request 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 3, or converted pursuant to Article 4, 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 as a result of any Securities, at the request of any Holder, being issued to a Person other than such Holder 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 this 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. 15 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 3, those converted pursuant to Article 4, 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, 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 Purchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any), accrued interest and Additional Interest, if any, on Securities (or portions thereof) payable on that date, then on and after such Fundamental Change Purchase Date or 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 and Additional Interest, if any, on them shall cease to accrue. (d) Subject to the restrictions contained in Section 2.09, 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 this 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. 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 with the consent of the Trustee 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. 16 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. Section 2.12. Legend; Additional Transfer and Exchange Requirements. (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set forth on the forms of Securities attached as Exhibit A (collectively, the "Legend"), or if a request is made to remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an Opinion of Counsel if requested by the Company or such Registrar, as may be reasonably required by the Company and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A or Rule 144 under the Securities Act or that such Securities are not "restricted" within the meaning of Rule 144 under the Securities Act; provided that no such evidence need be supplied in connection with the sale of such Security pursuant to a registration statement that is effective at the time of such sale. Upon (1) provision of such satisfactory evidence if requested or (2) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the Security is subsequently held by an Affiliate of the Company, the Legend shall be reinstated. (b) 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 this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Notwithstanding any other provisions of this 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. (c) Subject to Section 2.12(b) and in compliance with Section 2.12(d), every Security shall be subject to the restrictions on transfer provided in the Legend. Whenever any Restricted Security other than a Restricted 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, as to compliance with such restrictions on transfer. The Registrar shall not be required to accept for such 17 registration of transfer or exchange any Security not so accompanied by a properly completed certificate. (d) The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested by the Company or the Registrar, an Opinion of Counsel reasonably acceptable to the Company and the Registrar and addressed to the Company and the Registrar, to the effect that the transfer of such Security has been made in compliance with Rule 144 or such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The Company shall inform the Trustee of the effective date of any registration statement registering the offer and sale of the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the aforementioned Opinion of Counsel or registration statement. As used in Sections 2.12(c) and (d), the term "transfer" encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security. (e) The provisions below shall apply only to Global Securities: (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for purposes of this Indenture. (2) Notwithstanding any other provisions of this 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 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. 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 18 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 legends 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(e), 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 this 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(e), 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 this 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 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, canceled 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 of this Indenture. At any time prior to such cancellation, if any interest in a 19 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. (f) Until the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision thereto), any stock certificate representing Common Stock issued upon conversion of any Security shall bear a legend in substantially the following form, unless such Common Stock has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or transferred in compliance with Rule 144 under the Securities Act (or any successor provision thereto), or such Common Stock has been issued upon conversion of Securities that have been transferred pursuant to a registration statement that has been declared effective under the Securities Act or pursuant to Rule 144 under the Securities Act (or any successor provision thereto), or unless otherwise agreed by the Company in writing with written notice thereof to the transfer agent: THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS, AND, ACCORDINGLY, MAY NOT BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION UNDER THE SECURITIES ACT. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES TO OFFER, SELL OR OTHERWISE TRANSFER THE COMMON STOCK EVIDENCED HEREBY PRIOR TO THE DATE THAT IS TWO YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH CHATTEM INC. (THE "COMPANY") OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THE COMMON STOCK EVIDENCED HEREBY (OR ANY PREDECESSOR OF THE COMMON STOCK EVIDENCED HEREBY) (THE "RESALE RESTRICTION TERMINATION DATE") ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (C) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY'S AND THE TRANSFER AGENT'S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (C) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATIONS AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER SIDE OF THIS CERTIFICATE IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRANSFER AGENT. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. 20 Any such Common Stock as to which such restrictions on transfer shall have expired in accordance with their terms or as to which the conditions for removal of the foregoing legend set forth therein have been satisfied may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new certificate or certificates for a like number of shares of Common Stock, which shall not bear the restrictive legend required by this section. Section 2.13. CUSIP Numbers. The Company in issuing the Securities may use one or more "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers 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 numbers 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 numbers. The Company will promptly notify the Trustee of any change in the "CUSIP" numbers. ARTICLE 3 PURCHASE UPON FUNDAMENTAL CHANGE Section 3.01. Purchase at Holders' Option upon a Fundamental Change. (a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security shall have the right, at the option of the Holder, 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 Purchase Price, on the date (the "Fundamental Change Purchase Date") specified by the Company pursuant to subsection 3.01(b) that is not less than 30 days nor more than 45 days after the Fundamental Change Effective Date. (b) As promptly as practicable following the date when the Company publicly announces a Fundamental Change but in no event less than 10 Trading Days prior to the anticipated Fundamental Change Effective Date, 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 as required by applicable law) (the "Fundamental Change Company Notice"). The Fundamental Change Company Notice shall include the form of a Fundamental Change Purchase Notice to be completed by the Holder and shall state: (1) the events causing such Fundamental Change; (2) the date (or expected date) of such Fundamental Change; (3) the last date by which the Fundamental Change Purchase Notice must be delivered to elect the repurchase option pursuant to this Section 3.01; (4) the Fundamental Change Purchase Date; 21 (5) the Fundamental Change Purchase Price; (6) the Holder's right to require the Company to purchase the Securities; (7) the name and address of each Paying Agent and Conversion Agent; (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 4 and that Securities as to which a Fundamental Change Purchase Notice has been given may be converted into Common Stock pursuant to Article 4 of this Indenture only to the extent that the Fundamental Change Purchase Notice has been withdrawn in accordance with the terms of this Indenture; (10) the procedures that the Holder must follow to exercise rights under this Section 3.01; (11) the procedures for withdrawing a Fundamental Change Purchase Notice; (12) that, unless the Company fails to pay such Fundamental Change Purchase Price, Securities covered by any Fundamental Change Purchase Notice will cease to be outstanding and interest and Additional Interest, if any, will cease to accrue on and after the Fundamental Change Purchase Date; and (13) the CUSIP number of the Securities. At the Company's request, the Trustee shall give such Fundamental Change Company Notice in the Company's name and at the Company's expense; provided that, in all cases, the text of such Fundamental Change Company Notice shall be prepared by the Company. 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 3.01(a) upon delivery of a written notice (which shall be in substantially the form set forth in the form of Security attached as Exhibit A under the heading "Fundamental Change Purchase 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 Purchase 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 Purchase Date, subject to extension to comply with applicable law. 22 (1) The Fundamental Change Purchase 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, which portion must be $1,000 or an integral multiple of $1,000 and (C) that such Security shall be purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions specified in the Securities and in this Indenture. (2) The delivery of a Security for which a Fundamental Change Purchase Notice has been timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change Purchase Notice (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor. (3) The Company shall only be obliged to purchase, pursuant to this Section 3.01, 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 Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security). (4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.02. (5) A Paying Agent shall promptly notify the Company of the receipt by it of any Fundamental Change Purchase Notice or written withdrawal thereof. (6) Anything herein to the contrary notwithstanding, in the case of Global Securities, any Fundamental Change Purchase 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 3.02. Effect of Fundamental Change Purchase Notice. (a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Purchase Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such Security, subject to the occurrence of an absence of an Event of Default, or a continuation thereof (other than a Default in the payment of the Fundamental Change Purchase Price). Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (1) the Fundamental Change Purchase Date (provided that the conditions in Section 3.01 have been satisfied) and (2) the time of delivery of 23 such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock pursuant to Article 4 on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first been validly withdrawn in accordance with Section 3.02(b) with respect to the Securities to be converted. (b) A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which may be delivered by mail, 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 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 Purchase Date, specifying (1) 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 Applicable Procedures), (2) 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, and (3) the portion of the principal amount of the Security that will remain subject to the Fundamental Change Purchase Notice, which portion must be a principal amount of $1,000 or an integral multiple thereof. Section 3.03. Deposit of Fundamental Change Purchase Price. (a) On or before 10:00 a.m., New York City time, on the applicable Fundamental Change Purchase 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) an amount of money (in immediately available funds), sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of such Fundamental Change Purchase Date. (b) If a Paying Agent or the Trustee holds, in accordance with the terms hereof, money sufficient to pay the Fundamental Change Purchase Price of any Security for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, on immediately after the applicable Fundamental Change Purchase Date, such Security will cease to be outstanding, whether or not the Security is delivered to the Paying Agent or the Trustee, and interest and Additional Interest, if any, 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 Purchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities repurchased on or as soon as practicable after the Fundamental Change Purchase Date. (c) The Paying Agent will promptly return to the respective Holders thereof any Securities with respect to which a Fundamental Change Purchase Notice has been withdrawn in compliance with this Indenture. 24 (d) If a Fundamental Change Purchase Date falls after a Regular Record Date and on or before the related Interest Payment Date, then interest on the Securities payable on such Interest Payment 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 3.04. Repayment to The Company. To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company. Section 3.05. Securities Purchased in Part. Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Fundamental Change Purchase Date, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or any integral thereof), in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. Section 3.06. Compliance with Securities Laws upon Purchase of Securities. In connection with any offer to purchase of Securities under Section 3.01, 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 3.01 through 3.04 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 Indenture is hereby modified to the extent required for the Company to comply with such laws, rules and regulations. Section 3.07. Purchase of Securities in Open Market. The Company (a) on or prior to the date that is two years from the latest issuance of any Securities and in accordance with Section 2.11, shall surrender any Security purchased by the Company pursuant to this Article 3 to the Trustee for cancellation, and (b) after such date and in accordance with Section 2.11, may surrender such Security to the Trustee for cancellation. Any securities surrendered to the Trustee for cancellation may not be reissued or resold by the Company and will be canceled promptly in accordance with Section 2.11. The Company may repurchase Securities in the open market, by tender at any price or by negotiated transactions and such Securities may be reissued or resold, to the extent permitted by applicable law, or may be surrendered to the Trustee for cancellation. 25 ARTICLE 4 CONVERSION Section 4.01. Conversion Privilege and Conversion Rate. (a) Subject to the obligation and the right of the Company to pay some or all of the conversion consideration in cash in accordance with Section 4.13, and upon compliance with the provisions of this Article 4, 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 prior to the close of business on the Business Day immediately preceding the Final Maturity Date or such earlier date set forth in this Article 4, unless previously purchased by the Company at the Holder's option upon the occurrence of a Fundamental Change, at the Conversion Rate in effect at such time, determined as hereinafter provided and subject to the adjustments described below, only under the following circumstances: (1) during any fiscal quarter beginning after August 31, 2007, and only during such fiscal quarter, if, as of the last day of the immediately preceding fiscal quarter, the Closing Price per share of the Common Stock for at least 20 Trading Days in the period of the 30 consecutive Trading Days ending on the last Trading Day of such preceding calendar quarter was more than 130% of the Conversion Price (the "Conversion Trigger Price"); (2) if the Company distributes to all holders of Common Stock rights (including rights under a shareholder rights agreement) or warrants entitling them to purchase, for a period expiring within 45 days of the date of issuance, Common Stock at less than the Current Market Price of the Common Stock on the day of issuance; (3) if the Company distributes to all holders of Common Stock, assets, debt securities or rights to purchase the Company's securities, which distribution has a per share value exceeding 15% of the average of the Closing Prices of the Common Stock for the five consecutive Trading Days ending on the date immediately preceding the first public announcement of such distribution; (4) if a Fundamental Change occurs; (5) at any time during the one month period beginning on April 1, 2014 and ending at the close of business on the Business Day immediately preceding the Final Maturity Date; or (6) prior to April 1, 2014, during any five Business Day period after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of Securities, as determined following a request by a Holder in accordance with the procedures described below in Section 4.01(e)(ii), for each day of that period was less than 97% of the product of the Closing Price of the Common Stock and the then applicable Conversion Rate. 26 (b) In the case of a distribution contemplated by clauses (2) and (3) of Section 4.01(a), the Company shall notify Holders and Trustee at least 20 days prior to the ex-dividend date for such distribution (the "Distribution Notice"); provided that if the Company distributes rights pursuant to a shareholder rights agreement, it will notify the Holders of the Securities on the Business Day after the Company is required to give notice generally to its shareholders pursuant to such shareholder rights agreement if such date is less than 20 days prior to the date of such distribution. Once the Company has given the Distribution Notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the last Business Day preceding the ex-dividend date or the Company's announcement that such distribution will not take place. Notwithstanding the provisions of clauses (2) and (3) of Section 4.01(a), Holders may not convert the Securities if the Holders will be entitled to participate in such distribution on an as converted basis. The Company will provide written notice to the Conversion Agent as soon as reasonably practicable of any anticipated or actual event or transaction that will cause or causes the Securities to become convertible pursuant to clauses (2) or (3) of Section 4.01(a). (c) [Intentionally Omitted] (d) In the case of a transaction contemplated by clause (4) of section 4.01(a), the Company will notify the Holders and Trustee at least 10 Trading Days prior to the anticipated Fundamental Change Effective Date of any Fundamental Change. Holders may surrender Securities for conversion at any time beginning 10 Trading Days before the anticipated Fundamental Change Effective Date of a Fundamental Change and until the last Trading Day preceding the Fundamental Change Purchase Date. (e) (i) For each fiscal quarter of the Company, beginning with the fiscal quarter ending August 31, 2007, the Company will determine, on the first Business Day following the last Trading Day of such fiscal quarter, whether the Securities are convertible pursuant to clause (1) of Section 4.01(a), and, if so, will notify the Trustee in writing. Upon request of the Conversion Agent, the Company shall provide, or cause to be provided to, the Conversion Agent the Closing Price per share of Common Stock for the 30 consecutive Trading Days ending on the last Trading Day of the preceding fiscal quarter. (ii) The Company shall have no obligation to determine the Trading Price of the Securities and whether the Securities are convertible pursuant to clause (6) of Section 4.01(a) unless a Holder of Securities provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Securities would be less than 97% of the product of the Closing Price of the Common Stock and the Conversion Rate per $1,000 principal amount of Securities. At such time, the Company shall determine the Trading Price of the Securities beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Securities is greater than 97% of the product of the Closing Price of the Common Stock and the Conversion Rate per $1,000 principal amount of the Securities. (f) The conversion rights pursuant to this Article 4 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, but shall be exercisable only during the time 27 periods specified with respect to each circumstance pursuant to which the Securities become convertible, subject, in the case of conversion of any Global Security, to any Applicable Procedures. If a Security is convertible as a result of a Fundamental Change, such conversion right shall commence and terminate as set forth in Section 4.01(d). Securities in respect of which a Fundamental Change Purchase Notice has been delivered may not be surrendered for conversion pursuant to this Article 4 prior to a valid withdrawal of such Fundamental Change Notice in accordance with the provisions of Article 3. (g) Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. (h) 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, and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 4. (i) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(j) and Section 4.06. (j) If a Fundamental Change occurs as a result of a Termination of Trading or as a result of the occurrence of one of the events specified in clause (i), (ii), (iii) or (v) of the definition of the term Change in Control, the Company shall pay, to the extent set forth in this Section 4.01(j), a make-whole premium to a Holder who converts its Securities in connection with any such transaction by increasing the Conversion Rate applicable to such Securities. A conversion of Securities will be deemed for the purposes of this Section 4.01(j) to be "in connection with" a Fundamental Change if the Conversion Notice set forth in the form of Security attached as Exhibit A is received by the Conversion Agent on or subsequent to the date 10 Trading Days prior to the date announced by the Company as the anticipated Fundamental Change Effective Date but before the close of business on the Business Day immediately preceding the related Fundamental Change Purchase Date. Any increase in the applicable Conversion Rate shall be determined by reference to the table below and shall be based on the date on which the Fundamental Change Effective Date occurs and the price paid, or deemed to be paid, per share of Common Stock in the transaction constituting the Fundamental Change (the "Stock Price"). If holders of Common Stock receive only cash in the Fundamental Change, the Stock Price shall be the cash amount paid per share of Common Stock. In all other cases, the Stock Price shall be the average of the Closing Prices of the Common Stock for each of the 10 Trading Days immediately prior to but not including the Fundamental Change Effective Date. The following table sets forth the amount, if any, by which the applicable Conversion Rate shall increase for each Stock Price and Fundamental Change Effective Date set forth below.

The actual Stock Price and Fundamental Change Effective Date may not be set forth in the table, in which case: (i) if the actual Stock Price on the Fundamental Change Effective Date is between two Stock Prices in the table or the actual Fundamental Change Effective Date is between two Fundamental Change Effective Dates in the table, the amount of the Conversion Rate adjustment shall be determined by a straight-line interpolation between the adjustment amounts set forth for the two Stock Prices and the two Fundamental Change Effective Dates set forth in the table based on a 365-day year, as applicable; (ii) if the Stock Price on the Fundamental Change Effective Date exceeds $200.00 per share, subject to adjustment as described in Section 4.06, no adjustment to the applicable Conversion Rate will be made; and (iii) if the stock price on the Fundamental Change Effective Date is less than $59.03 per share, subject to adjustment as described in Section 4.06, no adjustment to the applicable conversion rate will be made. 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 in accordance with Section 4.06. The adjusted Stock Prices shall equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which shall be the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which shall be the Conversion Rate as so adjusted. The Conversion Rate adjustment amounts set forth in the table above shall be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06. Notwithstanding the foregoing paragraph, in no event will the Conversion Rate exceed 16.9405 per $1,000 principal amount of Securities, subject to adjustment in the manner set forth in clauses (1) through (4) of Section 4.06(a) hereof. (k) Except as set forth in Section 4.02(c), by delivering the amount of cash and/or the number of shares of Common Stock issuable on conversion to the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the Securities so converted and its obligation to pay accrued and unpaid interest, and Additional Interest if any, attributable 29 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). (l) Notwithstanding anything else contained herein, the Securities shall not become subject to conversion by reason of a merger, consolidation, or other transaction effected with the Company's direct or indirect Subsidiaries for the sole purpose of changing the Company's state of incorporation to any other state within the United States or the District of Columbia. Section 4.02. Conversion Procedure. (a) To convert a Security, the Holder must (1) complete and manually sign the Conversion Notice on the reverse of the Security and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, and (4) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the Holder satisfies all of those requirements is the "Conversion Date." Upon the conversion of a Security, the Company shall settle its conversion obligation in the manner set forth in Section 4.13. (b) The person in whose name the shares of Common Stock, if any, that are issued upon conversion shall be deemed to be a holder of record of such shares of Common Stock on the date on which such shares, if any, are delivered to the Holder in accordance with the provisions of Section 4.13. Except as set forth in this Indenture, no payment or adjustment will be made for dividends or distributions declared or made on shares of Common Stock issued upon conversion of a 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 conversion. 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), 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 Indenture, the Securities and the Registration Rights Agreement. If a Holder converts more than one Security at the same time, the amount of cash to be paid and the number of shares of Common Stock issuable upon the conversion, if any (and the amount of any cash in lieu of fractional shares pursuant to Section 4.03), 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 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 30 outstanding after such conversion is equal to $1,000 or any integral multiple of $1,000 in excess thereof. (f) Upon the Company's determination that a Holder is or will be entitled to convert its Securities pursuant to this Article 4, the Company will promptly after making such determination issue a press release and use reasonable efforts to post such information on the Company's website or otherwise publicly disclose such information. 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 for the current market value of the fractional shares. The current market value of a fractional share shall be determined (calculated to the nearest 1/100th of a share) by multiplying the arithmetic average of the Volume Weighted Average Price of the Common Stock for each of the twenty consecutive Trading Days of the Conversion Reference Period by such fractional share and rounding the product to the nearest whole cent. 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, if any, upon such conversion. The Company shall also pay any such tax with respect to cash received in lieu of fractional shares. The Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder's name. 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 because the shares are to be issued in a name other than the Holder's name. 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 duly authorized, validly issued, fully paid and nonassessable and shall be free from preemptive or similar rights of any securityholder of the Company 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. 31 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 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 (to the extent any shares may be 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 (to the extent any shares may be 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 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 32 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 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 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 to which the provisions of Section 4.06(a)(3) shall apply, (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 to which the provisions of Section 4.06(a)(6) shall apply) (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 a number of shares of Common Stock equal to the then applicable Conversion Rate 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 33 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 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 into a number of shares of Common Stock equal to the Conversion Rate. 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 so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect on 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 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 an equivalent distribution to the Holders of the Securities or 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 34 received if such Securities had been converted on the record date with respect to such distribution. (5) With respect to any rights or warrants (the "Rights") that may be issued or distributed pursuant to any existing rights plan of the Company or any rights plans implemented by the Company after the date of this Indenture (a "Rights Plan"), the Holders of Securities will receive, with respect to any 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 the Rights have separated from the shares of Common Stock in accordance with the provisions of the Rights Plan so that Holders would not be entitled to receive any rights in respect of the shares of Common Stock, if any, 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 constituting such rights 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. 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 record date relating to such Triggering Distribution. 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 into a number of shares of Common Stock equal to the Conversion Rate. 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. 35 (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 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 36 (A) the "ex" date (as hereinafter defined) 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) 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) 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), whose determination shall be conclusive and set forth in a board resolution of the Board of Directors) 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), 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)) that requires an adjustment to the Conversion Rate pursuant to Section 4.06(a)(1), (2), (3), (4), (5) or (6) 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 4.06(a)(9) 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; (B) with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular 37 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. (10) Subject to applicable stock exchange rules and listing standards, the Company shall be permitted to increase the Conversion Rate by any amount for a period of at least 20 days if the Board of Directors determines that such increase would be in the Company's best interest. Subject to applicable stock exchange rules and listing standards, the Company may also increase the Conversion Rate to avoid or diminish income tax to Holders of the Common Stock in connection with a dividend or distribution of Common Stock or similar event. (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) 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). 38 (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. (e) Notwithstanding the provisions set forth in Section 4.06(a), in no event shall the Conversion Rate exceed 16.9405 per $1,000 principal amount of Securities, subject to adjustment in the manner set forth in clauses (1) through (4) of Section 4.06(a). Section 4.07. No Adjustment. 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. (a) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in the Conversion Rate as last adjusted; provided, however, that any adjustments which would be required to be made but for this Section 4.07(a) shall be carried forward and taken into account in any subsequent adjustment. Notwithstanding the foregoing, all adjustments not previously made shall have effect with respect to any conversion on or after April 1, 2014. All calculations under this Article 4 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. (b) No adjustment in the Conversion Rate shall be required for (1) issuances of Common Stock pursuant to any present or future plan of the Company providing for the reinvestment of dividends or interest and the investment of additional optional amounts of Common Stock under any plan, (2) issuances of Common Stock or options or rights to purchase Common Stock pursuant to any present or future employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its subsidiaries, (3) issuances of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in clause (2) above and outstanding as of the Issue Date or (4) for accrued and unpaid interest and Additional Interest owed, if any. (c) To the extent that the Securities become convertible into the right to receive cash in accordance with the provision of Section 4.10, no adjustment need be made thereafter as to the cash. 39 Section 4.08. Notice of Adjustment. Whenever the Conversion Rate or conversion privilege is required to be adjusted pursuant to this Indenture, the Company shall promptly mail to Holders a notice of the adjustment and file with the Trustee an 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 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 to 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 settlement of the Conversion Value will be based on the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which Holders of Common Stock receive in such Business Combination in respect of each share of Common Stock. 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 Securities shall be convertible from and after the effective date of such Business Combination into the form of consideration elected by a majority of the Company's shareholders in such Business 40 Combination. Appropriate provisions will be made, as determined in good faith by the Company's Board of Directors, to preserve the settlement provisions in Section 4.13 following such Business Combination to the extent feasible. 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 4. 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 a full and unconditional guarantee by such other corporation of all the Company's obligations under the Indenture and the Securities and 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 3 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. The Trustee shall have no duty to determine when an adjustment under this Article 4 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, including the Officers' Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities. Section 4.12. [Intentionally Omitted] Section 4.13. Settlement of Conversion Obligation. (a) Holders surrendering Securities for conversion shall receive for each $1,000 principal amount of Securities surrendered for conversion: (A) cash in an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value; and (B) if the Conversion Value is greater than $1,000, a number of shares of Common Stock (the "Remaining Shares") equal to the sum of the Daily Share Amounts for each of the 20 consecutive Trading Days in the Conversion Reference Period, appropriately adjusted to reflect stock splits, stock dividends, combinations or similar events occurring during the Conversion Reference Period, subject to the Company's right to deliver cash in lieu of all or a portion of such Remaining Shares as set forth in Section 4.13(b); 41 provided that in no event shall the aggregate number of Remaining Shares, per $1,000 principal amount of Securities, exceed the Aggregate Share Cap. (b) On any day prior to the first Trading Day of the applicable Conversion Reference Period, the Company may specify a percentage of the Daily Share Amount that will be settled in cash (the "Cash Percentage"). If the Company elects to specify a Cash Percentage, the amount of cash that the Company will deliver in respect of each Trading Day in the applicable Conversion Reference Period will equal the product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading Day and (3) the Volume Weighted Average Price of the Common Stock for such Trading Day (provided that after the consummation of a Fundamental Change in which the consideration is comprised entirely of cash, the amount used in this clause (3) will be the cash price per share received by holders of the Common Stock in such Fundamental Change). The number of shares that the Company shall deliver in respect of each Trading Day in the applicable Conversion Reference Period will be a percentage of the Daily Share Amount equal to 100% minus the Cash Percentage. Upon making a determination that a percentage of the Daily Share Amount will be settled in cash, the Company shall promptly issue a press release and disclose such information on its website prior to the first Trading Day of the applicable Conversion Reference Period. If the Company does not specify a Cash Percentage by the start of the applicable Conversion Reference Period, the Company shall be required to settle 100% of the Daily Share Amount for each Trading Day in the applicable Conversion Reference Period with shares of Common Stock; provided, however, that the Company shall pay cash in lieu of fractional shares otherwise issuable upon conversion of Securities. (c) The Company shall determine the Conversion Value, Daily Share Amount and the number of shares of Common Stock, if any, to be issued upon conversion at the end of the applicable Conversion Reference Period. Upon conversion of a Security, the Company shall pay the cash and deliver the shares of Common Stock, as applicable, as promptly as practicable after the last Trading Day of the Conversion Reference Period but in any event not later than the third Trading Day following the last Trading Day of the Conversion Reference Period. For the purposes of Sections 4.13(a) and (b), in the event that any of Conversion Value, Daily Share Amounts or Volume Weighted Average Price cannot be determined for all portions of the Conversion Reference Period, the Company's Board of Directors shall in good faith determine the values necessary to calculate the Conversion Value, Daily Share Amounts and Volume Weighted Average Price, as applicable. ARTICLE 5 COVENANTS Section 5.01. Payment of Securities. (a) 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 Indenture. A payment of principal or interest or Additional Interest, if any, shall be considered paid on the date it is due if the Paying Agent (other than the Company) holds by 10:00 a.m., New York City time, on that date money, deposited by or on behalf of the Company sufficient to make the payment. Subject to 42 Section 4.02, 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, interest, Fundamental Change Purchase Price and Additional Interest, if any, in each case if payable, shall be considered paid on the applicable date due if on such date the Trustee or the Paying Agent holds, in accordance with this Indenture, money sufficient to pay all such amounts then due. The Company shall, to the fullest extent permitted by law, pay interest in immediately available funds on overdue principal amount and interest at the annual rate borne by the Securities compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand. (b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York (which shall initially be at the address set forth in Section 2.03(c)) or 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 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. (a) 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 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 EDGAR) system shall be deemed to be filed with the Trustee. The Company also shall comply with the provisions of TIA Section 314(a). (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). 43 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 on or about November 30, 2006), an Officers' Certificate as to the signer's knowledge of the Company's compliance with all terms, conditions and covenants on its part contained in this 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 Indenture. Section 5.04. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture. Section 5.05. Maintenance of Corporate Existence. Subject to Article 6, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. Section 5.06. Rule 144A Information Requirement. During the period prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, upon the request of any Holder or beneficial holder of the Securities, make available to such Holder or beneficial holder of Securities or any Common Stock issued upon conversion thereof which continue to be Restricted Securities in connection with any sale thereof and any prospective purchaser of Securities or such Common Stock designated by such Holder or beneficial holder, the information required pursuant to Rule 144A(d)(4) under the Securities Act and it will take such further action as any Holder or beneficial holder of such Securities or such Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time. Whether a person is a beneficial holder shall be determined by the Company. Section 5.07. Stay, Extension and Usury Laws. 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 or Additional 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 Indenture, and the 44 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 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 5.08. Payment of Additional Interest. If Additional Interest is payable by the Company pursuant to the Registration Rights Agreement, the Company shall deliver to the Trustee an Officers' Certificate to that effect stating (i) the amount of such Additional Interest that is payable, (ii) the reason why such Additional Interest is payable and (iii) the date on which such Additional Interest is payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to such Additional Interest, the Company shall deliver to the Trustee a certificate setting forth the particulars of such payment. Section 5.09. Maintenance of Office or Agency. 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, purchase or redemption and where notices and demands to or upon the Company in respect of the Securities and this 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. 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. ARTICLE 6 CONSOLIDATION AND MERGER Section 6.01. Company May Consolidate, Etc., Only on Certain Terms. The Company may not consolidate with or merge into any Person or convey, transfer or lease the property and assets, substantially as an entirety, of the Company to another Person, other than to one or more of the Company's wholly-owned subsidiaries, unless: (1) Either (A) the Company is the continuing entity or (B) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person which acquires by conveyance, transfer or lease all or substantially all of 45 the properties and assets of the Company, shall (i) be a corporation, limited liability company, partnership, trust or other business entity organized and existing under the laws of the United States of America or any State thereof or the District of Columbia and (ii) such Person (if other than the Company) expressly assumes, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, the obligations of the Company under the Securities and this Indenture and the performance or observance of every covenant and provision of this Indenture and the Securities required on the part of the Company to be performed or observed (including, without limitation, the obligation to convert Securities in accordance with Article 4), by supplemental indenture satisfactory in form to the Trustee, executed and delivered to the Trustee, by the Person (if other than the Company) formed by such consolidation or into which the Company shall have been merged or by the Person which shall have acquired the Company's assets; (2) after giving effect to such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing; and (3) the Company shall have, at or prior to the effective date of such consolidation, merger or transfer, delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer complies with this Article 6.01 and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Article, and that all conditions precedent herein provided for relating to such transaction have been complied with. Section 6.02. Successor Substituted. Upon any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease substantially as an entirety, of the properties and assets of the Company and its Subsidiaries, taken as a whole, in accordance with Section 6.01, the successor Person formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, and except for obligations the predecessor Person may have under a supplemental indenture, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities. ARTICLE 7 DEFAULT AND REMEDIES Section 7.01. Events of Default. (a) An "Event of Default" shall occur if: 46 (1) the Company shall fail to pay when due the Principal or Fundamental Change Purchase Price of any Security, when the same becomes due and payable whether at the Final Maturity Date, upon repurchase, acceleration or otherwise; or (2) the Company shall fail to pay an installment of cash interest or Additional Interest, if any, on any of the Securities, which failure continues for 30 days after the date when due; or (3) the Company shall fail to deliver when due all cash and shares of Common Stock, if any, deliverable upon conversion of the Securities, which failure continues for 15 days; or (4) the Company shall fail to provide a Fundamental Change Company Notice when due; (5) the Company shall fail to perform or observe (or obtain a waiver with respect to) any other term, covenant or agreement contained in the Securities or this Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or (6) the Company shall default in the payment of principal by the end of any applicable grace period or resulting in acceleration of other Indebtedness of the Company for borrowed money where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $7.5 million and such acceleration has not been rescinded or annulled or such Indebtedness repaid within a period of 30 days after receipt of a Notice of Default, provided that if any such default is cured, waived, rescinded or annulled, then the Event of Default by reason thereof would not be deemed to have occurred; or (7) the Company or any of its Subsidiaries shall fail to pay final judgment aggregating in excess of $7.5 million (excluding therefrom any amount covered by insurance as to which the insurer has acknowledged in writing its coverage obligation), which judgments are not paid, discharged or stayed for a period of 60 days; or (8) the Company, or any Significant Subsidiary of the Company, pursuant to or within the meaning of any Bankruptcy Law: (A) commences as a debtor a voluntary case or proceeding; (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; (C) consents to the appointment of a Receiver of it or for all or substantially all of its property; (D) makes a general assignment for the benefit of its creditors; 47 (E) files a petition in bankruptcy or answer or consent seeking reorganization or relief; or (F) consents to the filing of such a petition or the appointment of or taking possession by a Receiver; or (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) grants relief against the Company or any Significant Subsidiary of the Company in an involuntary case or proceeding or adjudicates the Company or any Significant Subsidiary of the Company insolvent or bankrupt; (B) appoints a Receiver of the Company or any Significant Subsidiary of the Company or for all or substantially all of the property of the Company or any Significant Subsidiary of the Company; or (C) orders the winding up or liquidation of the Company or any Significant Subsidiary of the Company; and in each case the order or decree remains unstayed and in effect for 60 consecutive days. The term "Bankruptcy Law" means Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for the relief of debtors. The term "Receiver" means any receiver, trustee, assignee, liquidator, sequestrator or similar official under any Bankruptcy Law. (b) Notwithstanding Section 7.01(a), no Event of Default under clauses (5) or (6) of Section 7.01(a) 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 (5) or (6) of Section 7.01(a), as applicable, after receipt of such notice. 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. The Trustee shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer with responsibility for this Indenture at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder or unless a Trust Officer with responsibility for this Indenture acquires actual knowledge of such Event of Default in the course of performing other duties pursuant to this Indenture. 48 Section 7.02. Acceleration. If an Event of Default (other than an Event of Default specified in clause (8) or (9) of Section 7.01(a)) 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, and accrued and unpaid Additional 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, and such accrued and unpaid Additional Interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 7.01(a)(8) or (9) occurs in respect of the Company and is continuing, the principal amount and accrued but unpaid interest, if any, and accrued and unpaid Additional 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) to the extent the payment of such interest is lawful, interest (calculated at the rate per annum borne by the Securities) on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under Section 8.07 have been made. No such rescission shall affect any subsequent Default or impair any right consequent thereto. Section 7.03. Other Remedies. (a) Subject to Section 8.01(a), if an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect payment of the principal amount and accrued and unpaid interest, if any, and accrued and unpaid Additional Interest, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. (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, 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 and cash, as 49 applicable, or any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 10.02, 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 to exist. 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 this 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 this 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 4) unless: (1) the Holder gives to the Trustee written notice of a continuing Event of Default; (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 reasonable 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 this 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 this Indenture, the right of any Holder of a Security to receive payment of the principal amount, interest, Fundamental Change Purchase Price, if any, or Additional Interest, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and this Indenture (whether upon 50 repurchase or otherwise), and to convert such Security in accordance with Article 4, 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 4, 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) 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 reasonable 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 to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 8.07, and to the extent that such payment of the reasonable compensation, 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. Section 7.10. Priorities. (a) If the Trustee collects any money pursuant to this Article 7, it shall pay out the money in the following order: (1) First, to the Trustee for amounts due under Section 8.07; (2) Second, to Holders for amounts due and unpaid on the Securities for the principal amount, interest, and Additional Interest, as applicable, ratably, without preference or priority of any kind, according to such respective amounts due and payable on the Holders' Securities; 51 (3) Third, to such other Person or Persons, if any, to the extent entitled thereto; and (4) Fourth, the balance, if any, to the Company. (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.10. Section 7.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 7.07 or a suit by Holders of more than 10% in aggregate principal amount of the Securities then outstanding. This Section 7.11 shall be in lieu of Section 315(e) of the TIA and such Section 315(e) is hereby expressly excluded from this Indenture, as permitted by the TIA. ARTICLE 8 TRUSTEE Section 8.01. Obligations of Trustee. (a) If an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. (b) Except during the continuance of an Event of Default of which a Responsible Officer of the Trustee shall have actual knowledge: (1) the Trustee need perform only those duties as are specifically set forth in this Indenture and no others; and (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee, however, shall examine any certificates and opinions which by any provision hereof are specifically required to be delivered to the Trustee to determine whether or not they conform to the requirements of this Indenture, but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein. 52 This Section 8.01(b) shall be in lieu of Section 315(a) of the TIA and such Section 315(a) is hereby expressly excluded from this Indenture, as permitted by the TIA.

This Section 8.01(c) shall be in lieu of Sections 315(d)(1), 315(d)(2) and 315(d)(3) of the TIA and such Sections are hereby expressly excluded from this Indenture as permitted by the TIA. (d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers unless the Trustee shall have received adequate security or indemnity in its opinion against potential costs and liabilities incurred by it relating thereto. (e) Every provision of this Indenture that in any way relates to the Trustee is subject to subsections (a), (b), (c) and (d) of this Section 8.01.

The Trustee need not investigate any fact or matter stated in the document. 53 (2) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel, which shall conform to Section 11.04(b). The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel. (3) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys or custodians, and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent, attorney or custodian appointed by the Trustee with due care.

(5) The Trustee may consult with counsel of its selection, and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection in respect of any such action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel. (6) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture or to institute, conduct or defend any litigation hereunder or in relation hereto at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. (7) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand from the Company's own funds. (8) The Trustee shall not be deemed to have notice or knowledge of any Default, Event of Default, or Fundamental Change unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee at the Corporate Trust Office, and such notice references the Securities and this Indenture. In the absence of receipt of such notice or actual knowledge, the Trustee may conclusively assume that there is no Default, Event of Default, or Fundamental Change. 54 (9) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including, without limitation as Paying Agent, Registrar and Conversion Agent, and to each agent, custodian and other Person employed to act hereunder. (10) The right of the Trustee to perform any discretionary act enumerated in this Indenture shall not be construed as a duty, and the Trustee shall not be answerable for other than its own gross negligence or willful misconduct in the performance of such act. Section 8.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 8.10 and 8.11. Section 8.04. Trustee's Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities and the Trustee assumes no responsibility for their correctness. It shall not be accountable for the Company's use of the proceeds from the Securities and it shall not be responsible for any statement in the Securities other than its certificate of authentication. Section 8.05. Notice of Default or Events of Default. If a Default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder of a Security notice of all uncured Defaults or Events of Default known to it within 90 days after it occurs or, if later, within 15 days after it becomes known to the Trustee. However, the Trustee may withhold the notice if and for so long as a committee of its Trust Officers in good faith determines that withholding notice is in the interests of Holders of Securities, except in the case of a Default or an Event of Default in payment of the principal of, or premium, if any, or interest on any Security when due or in the payment of any redemption or purchase obligation, or the Company's failure to convert Securities when obligated to convert them. This Section 8.05 is in lieu of section 315(b) of the TIA and such provision is expressly excluded from this Indenture as permitted by the TIA. Section 8.06. Reports by Trustee to Holders. (a) If a report is required by TIA Section 313, within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder of Securities a brief report dated as of such May 15 that complies with TIA Section 313(a). If required by TIA Section 313, the Trustee also shall comply with TIA Sections 313(b)(2) and (c). 55 (b) A copy of each report at the time of its mailing to Holders of Securities shall be mailed to the Company and, to the extent required by the TIA, filed with the SEC, and each stock exchange, if any, on which the Securities are listed. The Company shall notify the Trustee whenever the Securities become listed on any stock exchange or listed or admitted to trading on any quotation system and any changes in the stock exchanges or quotation systems on which the Securities are listed or admitted to trading and of any delisting thereof. Section 8.07. Compensation and Indemnity. (a) The Company shall pay to the Trustee from time to time such compensation (as agreed to from time to time by the Company and the Trustee in writing) for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon request for all reasonable disbursements, expenses and advances incurred or made by it. Such expenses may include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. (b) The Company shall indemnify the Trustee or any predecessor Trustee (which for purposes of this Section 8.07 shall include its officers, directors, employees and agents) for, and hold it harmless against, any and all loss, liability or expense including taxes (other than franchise taxes and taxes based upon, measured by or determined by the income of the Trustee), incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture or any action or failure to act as authorized or within the discretion or rights or powers conferred upon the Trustee hereunder including the reasonable costs and expenses of the Trustee and its counsel in defending (including reasonable legal fees and expenses) itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company promptly of any claim asserted against the Trustee for which it may seek indemnity. The Company need not pay for any settlement effected without its prior written consent, which shall not be unreasonably withheld. Anything in this Indenture to the contrary notwithstanding, in no event shall the Trustee be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. (c) The Company need not reimburse the Trustee for any expense or indemnify it against any loss or liability incurred by it resulting from its gross negligence, willful misconduct or bad faith. (d) The Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee. The obligations of the Company under this Section 8.07 shall survive the satisfaction and discharge of this Indenture or the resignation or removal of the Trustee. (e) When the Trustee incurs expenses or renders services after an Event of Default specified in clause (8) or (9) of Section 7.01(a) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. The provisions of this Section shall survive the termination of this Indenture. 56 Section 8.08. Replacement of Trustee. (a) The Trustee may resign by so notifying the Company. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company and may, with the Company's written consent, appoint a successor Trustee. The Company may remove the Trustee at any time, so long as no Default or Event of Default has occurred and is continuing, and appoint a Successor Trustee in accordance with this Section 8.08. (b) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. If the Company fails to promptly appoint a successor Trustee, the Trustee shall have the right to choose a qualified Trustee as successor, and the Company shall appoint such successor as Trustee. The resignation or removal of a Trustee shall not be effective until a successor Trustee shall have delivered the written acceptance of its appointment as described below. (c) If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of 10% in principal amount of the Securities then outstanding may petition any court of competent jurisdiction for the appointment of a successor Trustee at the expense of the Company.

The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, as in effect on the date of the Indenture. This Security is subject to all such terms, and the Holder of this security is referred to the Indenture and said Act for a statement of them. Capitalized terms not otherwise defined herein have the meaning ascribed to such terms in the Indenture. The Securities are unsecured obligations of the Company limited to $100,000,000 aggregate principal amount. The Indenture does not limit other debt of the Company, secured or unsecured. 5. PURCHASE OF SECURITIES OF HOLDERS' OPTION UPON A FUNDAMENTAL CHANGE If a Fundamental Change occurs prior to the Final Maturity Date, 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, 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 Fundamental Change Effective Date, at a purchase price equal to 100% of the principal amount thereof together with accrued and unpaid interest, if any, and accrued and unpaid Additional Interest, if any, to, but excluding, the Fundamental Change Purchase Date.

CONVERSION Subject to and upon compliance with the provisions of the Indenture and upon the occurrence of the events specified in the Indenture, a Holder may surrender for conversion any Security that is $1,000 principal amount or integral multiples thereof. In lieu of receiving shares of Common Stock, a Holder will receive, for each $1,000 principal amount of Securities surrendered for conversion: o cash in an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value; and o if the Conversion Value is greater than $1,000, a number of shares of Common Stock equal to the sum of the Daily Share Amounts, for each of the twenty A-6 consecutive Trading Days in the Conversion Reference Period, appropriately adjusted to reflect stock splits, stock dividends, combinations or similar events occurring during the Conversion Reference Period, subject to the Company's right to deliver cash in lieu of all or a portion of such shares as described in the Indenture; provided that in no event shall the aggregate number of shares of Common Stock to be issued pursuant to the foregoing clause, per $1,000 principal amount of Securities, exceed the Aggregate Share Cap, as defined in the Indenture. The Conversion Rate on any Securities surrendered in connection with a Fundamental Change may be increased by an amount, if any, determined in accordance with Section 4.01(j) of the Indenture. 7. DENOMINATIONS, TRANSFER, EXCHANGE The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount.

PERSONS DEEMED OWNERS The Holder of a Security may be treated as the owner of it for all purposes. 9. 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.
