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 authenticating agent. An authenticating agent so appointed has the same rights as a Securities Agent to deal with the Company and its Affiliates.

If a Company Order pursuant to this Section 2.02 has been, or simultaneously is, delivered, then any instructions by the Company to the Trustee with respect to endorsement, delivery or redelivery of a Security that is a Global Security shall be in writing but need not comply with Section 14.03 and need not be accompanied by an Opinion of Counsel.

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

The Company shall maintain, or shall cause to be maintained, (i) an office or agency in The Borough of Manhattan, The City of New York, where Securities may be presented for registration of transfer or for exchange (“Registrar”), (ii) an office or agency in The Borough of Manhattan, The City of New York, where Securities may be presented for payment (“Paying Agent”) and (iii) an office or agency in the Borough of Manhattan, The City of New York, where Securities may be presented for conversion (“Conversion Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may appoint or change one or more co-registrars, one or more additional paying agents and one or more additional conversion agents without notice and may act in any such capacity on its own behalf. The term “Registrar” includes any co-registrar; the term “Paying Agent” includes any additional paying agent; and the term “Conversion Agent” includes any additional conversion agent.

The Company shall enter into an appropriate agency agreement with any Securities Agent not a party to this Indenture. Such agency agreement shall implement the provisions of this Indenture that relate to such Securities Agent. The Company shall notify the Trustee of the name and address of any Securities Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent or Conversion Agent, the Trustee shall act as such.

The Company initially appoints the Trustee as Paying Agent, Registrar and Conversion Agent.

Section 2.04. Paying Agent to Hold Money in Trust. Each Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all moneys held by the Paying Agent for the payment of the Securities, and shall notify the Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and account for any funds so paid by it. Upon payment over to the Trustee, the Paying Agent shall have no further liability for such money. If the Company acts as

Paying Agent, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent.

Section 2.05. Holder Lists. 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. If the Trustee is not the Registrar, the Company shall furnish, or shall cause to be furnished, to the Trustee 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 appearing in the security register of the Registrar.

Section 2.06. Transfer and Exchange. Subject to Sections 2.15 and 2.16 hereof, where Securities are presented to the Registrar with a request to register their transfer or to exchange them for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer and exchanges, the Trustee shall authenticate Securities at the Registrar’s request or upon the Trustee’s receipt of a Company Order therefor. The Company, the Registrar or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security for which a Repurchase Notice has been delivered, and not withdrawn, in accordance with this Indenture, except if the Company has defaulted in the payment of the Fundamental Change Repurchase Price with respect to such Security or to the extent that a portion of such Security is not subject to such Repurchase Notice.

No service charge shall be made for any transfer, exchange or conversion of Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in connection with any transfer, exchange or conversion of Securities, other than exchanges pursuant to Sections 2.07, 2.10, 3.02, 9.04 or 10.02, in each case, not involving any transfer.

Section 2.07. Replacement Securities. If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate, at the Holder’s expense, a replacement Security upon surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken Security, if required by the Trustee or the Company, indemnity (including in the form of a bond) must be provided by the Holder that is reasonably satisfactory to the Trustee and the Company to indemnify and hold harmless the Company, the Trustee or any Securities Agent from any loss that any of them may suffer if such Security is replaced.

In case any such mutilated, lost, destroyed or wrongfully taken Security has become due and payable, the Company in its discretion may, instead of issuing a new Security, pay the amounts due in respect of such Security as provided hereunder.

Every replacement Security is an additional obligation of the Company only as provided in Section 2.08.

Section 2.08. Outstanding Securities. Securities outstanding at any time are all the Securities authenticated by the Trustee except for those converted, those cancelled by it, those delivered to it for cancellation and those described in this Section 2.08 as not outstanding. Except to

the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it, or a court holds, that the replaced Security is held by a protected purchaser.

If the Paying Agent (in the case of a Paying Agent other than the Company) holds on a Fundamental Change Repurchase Date or the Maturity Date, money sufficient to pay the aggregate Fundamental Change Repurchase Price or principal amount (plus accrued and unpaid interest, if any), as the case may be, with respect to all Securities to be repurchased or paid on such Fundamental Change Repurchase Date or the Maturity Date, as the case may be, in each case, payable as herein provided on such Fundamental Change Repurchase Date or the Maturity Date, then (unless there shall be a Default in the payment of such aggregate Fundamental Change Repurchase Price or principal amount, or of such accrued and unpaid interest), except as otherwise provided herein, on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall cease to accrue, and such Securities shall be deemed to be paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders of such Securities shall terminate with respect to such Securities, other than the right to receive the Fundamental Change Repurchase Price or principal amount, as the case may be, plus, if applicable, such accrued and unpaid interest, in accordance with this Indenture.

If a Security is converted in accordance with Article 10 then, from and after the time of such conversion on the Conversion Date, such Security shall cease to be outstanding, and interest, if any, shall cease to accrue on such Security unless there shall be a Default in the payment or delivery of the consideration payable and/or deliverable hereunder upon such conversion (except that any such Security will remain outstanding for the purpose of receiving any interest or other amounts due following such conversion as set forth in this Indenture).

Section 2.09. Securities Held by the Company or an Affiliate. In determining whether the Holders of the required aggregate principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company or any of its Subsidiaries or Affiliates shall be considered as though not outstanding, except that, for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have been pledged in good faith may be considered to be outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee, the pledgee’s right so to concur with respect to such Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company or an Affiliate of any such other obligor. In case of a dispute as to whether the pledgee has established the foregoing, any decision by the Trustee taken upon the advice of counsel shall provide full protection to the Trustee. Upon request of the Trustee, the Company shall furnish to the Trustee promptly an Officer’s Certificate listing and identifying all Securities, if any, known by the Company to be owned or held by or for the account of any of the above described Persons; and, subject to Section 7.01 and Section 7.02, the Trustee shall be entitled to accept such Officer’s Certificate as conclusive evidence of the facts therein set forth and of the fact that all Securities not listed therein are outstanding for the purpose of any such determination.

Section 2.10. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall, upon receipt of a Company Order therefor, authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee, upon receipt of a Company Order therefor, shall authenticate definitive Securities in exchange for temporary Securities. Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance with the terms of this Indenture.

Section 2.11. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange, payment, conversion or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation or that any Holder has converted pursuant to Article 10. All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary procedure for the disposal of cancelled securities, and certification of such disposal shall be delivered by the Trustee to the Company unless the Company shall, by a Company Order, direct that cancelled Securities be returned to it.

Section 2.12. Defaulted Interest. If, and to the extent, the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not prohibited by applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities. The Company may pay the defaulted interest (plus interest on such defaulted interest) to the Persons who are Holders on a subsequent special record date. The Company shall fix such special record date and payment date. At least fifteen (15) calendar days before the special record date, the Company shall mail to Holders a notice that states the special record date, payment date and amount of interest to be paid. Upon the due payment in full, interest shall no longer accrue on such defaulted interest pursuant to this Section 2.12.

Section 2.13. CUSIP Numbers. The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee shall use the CUSIP numbers in notices as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities; and provided further that reliance may be placed only on the other identification numbers printed on the Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee of any change in the CUSIP numbers.

Section 2.14. Deposit of Moneys. Prior to 11:00 A.M., New York City time, on each Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date, the Company shall deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, sufficient to make cash payments, if any, due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date, as the case may be.

If any Interest Payment Date, the Maturity Date or any Fundamental Change Repurchase Date falls on a date that is not a Business Day, the payment due on such Interest Payment Date, the Maturity Date or such Fundamental Change Repurchase Date, as the case may be, shall be postponed until the next succeeding Business Day, and no interest or other amount shall accrue as a result of such postponement.

Section 2.15. Book-Entry Provisions for Global Securities. (a) Global Securities initially shall (i) be registered in the name of the Depositary, its successors or their respective nominees, (ii) be delivered to the Trustee as custodian for the Depositary, its successors or their respective nominees, as the case may be, and (iii) bear the legends such Global Securities are required to bear under Section 2.17.

Members of, or participants in, the Depositary (“Participants”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global 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 impair, as between the Depositary and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

(b) Transfers of Global Securities shall be limited to transfers in whole, but not in part, to the Depositary, its successors or their respective nominees. In addition, one or more Physical Securities shall be transferred to each owner of a beneficial interest in a Global Security, as identified by the Depositary, in exchange for its beneficial interest in the Global Securities if (i) the Depositary notifies the Company that the Depositary is unwilling or unable to continue as depositary for any Global Security, or the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange Act, and, in either case, a successor Depositary is not appointed by the Company within ninety (90) days of such notice or cessation or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the beneficial owner of the relevant Securities to issue Physical Securities. For the avoidance of doubt, if any event described in clause (i) of the immediately preceding sentence occurs, any owner of a beneficial interest in any Global Security will be entitled to receive one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities, and if any event described in clause (ii) of the immediately preceding sentence occurs, only the beneficial owner that has made a written request to the Registrar will be entitled to receive one or more Physical Securities in exchange for its beneficial interest or interests in the Global Securities. The Company may also exchange beneficial interests in a Global Security for one or more Physical Securities registered in the name of the owner of beneficial interests if the Company and the owner of such beneficial interests agree to so exchange.

(c) In connection with the transfer of a Global Security in its entirety to beneficial owners pursuant to Section 2.15(b), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations.

(d) Any Physical Security delivered in exchange for an interest in a Global Security pursuant to Section 2.15(b) shall, except as otherwise provided by Section 2.16, bear the Security Private Placement Legend.

(e) The Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Indenture or the Securities.

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

(g) Neither the Trustee nor any Securities Agent shall have any responsibility for any actions taken or not taken by the Depositary.

Section 2.16. Special Transfer Provisions. (a) Notwithstanding any other provisions of this Indenture, but except as provided in Section 2.15(b), a Global 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.

(b) Upon the transfer, exchange or replacement of Securities not bearing the Security Private Placement Legend, unless the Company notifies the Registrar otherwise, the Registrar shall deliver Securities that do not bear the Security Private Placement Legend. Upon the transfer, exchange or replacement of Securities bearing the Security Private Placement Legend, the Registrar shall deliver only Securities that bear the Security Private Placement Legend unless (i) the requested transfer, exchange or replacement is after the Resale Restriction Termination Date, (ii) there is delivered to the Trustee and the Company an opinion of counsel reasonably satisfactory to the Company and addressed to the Company to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act or (iii) such Security has been sold pursuant to an effective registration statement under the Securities Act and the Holder selling such Securities has delivered to the Registrar a notice in the form of Exhibit C hereto. Upon any transfer or exchange of a beneficial interest in the Securities in connection with which the Security Private Placement Legend will be removed in accordance with this Indenture (including, without limitation, an exchange of a Global Security in whole in accordance with the applicable procedures), the Trustee shall increase the principal amount of the Global Security that does not constitute a Restricted Security by the principal amount of such transfer or exchange and likewise reduce the principal amount of the Global Security that does constitute a Restricted Security.

(c) By its acceptance of any Security or share of Common Stock bearing the Security Private Placement Legend or the Common Stock Private Placement Legend, each holder thereof acknowledges the restrictions on transfer of such security set forth in this Indenture and in the Security Private Placement Legend or Common Stock Private Placement Legend, as applicable, and

agrees that it will transfer such security only as provided in this Indenture and as permitted by applicable law.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to Section 2.15 or this Section 2.16. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

(d) Any Securities that are purchased or owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Securities no longer being Restricted Securities.

(e) The Company may, to the extent permitted by law, purchase the Securities in the open market or by tender offer at any price or by private agreement without giving prior notice to Holders. The Company may, at its option and to the extent permitted by law, reissue, resell or surrender to the Trustee for cancellation any Securities the Company purchases in this manner, in the case of a re-issuance or resale, so long as such Securities do not constitute Restricted Securities upon such re-issuance or resale. Securities surrendered to the Trustee for cancellation may not be reissued or resold and shall be promptly cancelled pursuant to Section 2.11.

Section 2.17. Restrictive Legends. Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “Security Private Placement Legend”) as set forth in Exhibit B-1A on the face thereof until the later of (i) the date that is one year after the last date of original issuance of such Securities, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereto, and (ii) such later date, if any, as may be required by applicable law (such date, the “Resale Restriction Termination Date”). Each certificate representing shares of Common Stock issued upon conversion of any Security, shall, upon issuance, if such shares constitute Restricted Securities at their time of issuance, bear the legend (the “Common Stock Private Placement Legend”) as set forth in Exhibit B-1B on the face thereof until the Resale Restriction Termination Date.

Section 3.01. No Redemption. The Securities shall not be redeemable at the option of the Company prior to the Maturity Date, and no sinking fund is provided for the Securities.

Section 3.02. Repurchase at Option of Holder Upon a Fundamental Change. (a) If a Fundamental Change occurs, each Holder of Securities shall have the right (the “Fundamental Change Repurchase Right”), at such Holder’s option, to require the Company to repurchase (a “Repurchase Upon Fundamental Change”) all of such Holder’s Securities (or portions thereof that are integral multiples of $1,000 in principal amount), on a date selected by the Company (the “Fundamental Change Repurchase Date”), which shall be no later than thirty five (35) Business Days, and no earlier than twenty (20) Business Days, after the date the Fundamental Change Notice is mailed in accordance with Section 3.02(b), at a price, payable in cash, equal to one hundred percent (100%) of the principal amount of the Securities (or portions thereof) to be so repurchased,

plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”), upon:

(i) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice, no later than the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, of a Repurchase Notice, in the form set forth in the Securities or any other form of written notice substantially similar thereto, in each case, duly completed and signed, with appropriate signature guarantee, stating:

(A) the certificate number(s) of the Securities that the Holder will deliver to be repurchased, if such Securities are Physical Securities;

(B) the principal amount of Securities to be repurchased, which must be $1,000 or an integral multiple thereof; and

(C) that such principal amount of Securities are to be repurchased pursuant to the terms and conditions specified in this Section 3.02; and

(ii) delivery to the Company (if it is acting as its own Paying Agent), or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice, at any time after the delivery of such Repurchase Notice, of such Securities (together with all necessary endorsements) with respect to which the Fundamental Change Repurchase Right is being exercised;

provided, however, that if such Fundamental Change Repurchase Date is after a Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then the full amount of accrued and unpaid interest, if any, to, but excluding, such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Securities at the Close of Business on such Record Date (without any surrender of such Securities by such Holder), and the Fundamental Change Repurchase Price shall not include any accrued but unpaid interest.

If such Securities are held in book-entry form through the Depositary, the delivery of any Securities, Repurchase Notice, Fundamental Change Notice or notice of withdrawal pursuant to the second immediately succeeding paragraph shall comply with applicable procedures of the Depositary.

Upon such delivery of Securities to the Company (if it is acting as its own Paying Agent) or such Paying Agent, such Holder shall be entitled to receive, upon request, from the Company or such Paying Agent, as the case may be, a nontransferable receipt of deposit evidencing such delivery.

Notwithstanding anything herein to the contrary, any Holder that has delivered the Repurchase Notice contemplated by this Section 3.02(a) to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice shall have the right to withdraw such Repurchase Notice by delivery, at any time prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date (or, if there shall be a Default in the payment of the Fundamental Change Repurchase, at any time during which such Default is continuing), of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying Agent, which notice shall be delivered in accordance with, and contain the information specified in, Section 3.02(b)(x).

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

(b) Within 10 days after the occurrence of a Fundamental Change, the Company shall mail, or cause to be mailed, to all Holders of the Securities at their addresses shown in the register of the Registrar, and to beneficial owners as required by applicable law, a notice (the “Fundamental Change Notice”) of the occurrence of such Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The Company shall deliver a copy of the Fundamental Change Notice to the Trustee. Each Fundamental Change Notice shall state:

(iv) the last date on which the Fundamental Change Repurchase Right may be exercised, which shall be the Business Day immediately preceding the Fundamental Change Repurchase Date;

(vii) the procedures that a Holder must follow to exercise the Fundamental Change Repurchase Right;

(viii) that the Fundamental Change Repurchase Price for any Security as to which a Repurchase Notice has been given and not withdrawn will be paid no later than the later of such Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the Security (together with all necessary endorsements);

(ix) that, except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, on and after such Fundamental Change Repurchase Date (unless there shall be a Default in the payment of the Fundamental Change Repurchase Price), interest on Securities subject to Repurchase Upon Fundamental Change will cease to accrue, and all rights of the Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, the Fundamental Change Repurchase Price;

(x) that a Holder will be entitled to withdraw its election in the Repurchase Notice prior to the Close of Business on the Business Day immediately preceding the Fundamental Change Repurchase Date, or such longer period as may be required by law, by means of a letter or telegram, telex or facsimile transmission (receipt of which is confirmed and promptly followed by a letter) setting forth the name of such Holder, a statement that such Holder is withdrawing its election to have Securities purchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change, the certificate number(s) of such Securities to be so withdrawn, if such Securities are

Physical Securities, the principal amount of the Securities of such Holder to be so withdrawn, which amount must be $1,000 or an integral multiple thereof and the principal amount, if any, of the Securities of such Holder that remain subject to the Repurchase Notice delivered by such Holder in accordance with this Section 3.02, which amount must be $1,000 or an integral multiple thereof; provided, however, that if there shall be a Default in the payment of the Fundamental Change Repurchase Price, a Holder shall be entitled to withdraw its election in the Repurchase Notice at any time during which such Default is continuing;

(xi) the Conversion Rate and any adjustments to the Conversion Rate that will result from such Fundamental Change;

(xii) that Securities with respect to which a Repurchase Notice is given by a Holder may be converted pursuant to Article 10 only if such Repurchase Notice has been withdrawn in accordance with this Section 3.02 or the Company defaults in the payment of the Fundamental Change Repurchase Price; and

At the Company’s request, upon prior notice reasonably acceptable to the Trustee, the Trustee shall mail such Fundamental Change Notice in the Company’s name and at the Company’s expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by the Company.

No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right pursuant hereto to exercise a Fundamental Change Repurchase Right.

(c) Subject to the provisions of this Section 3.02, the Company shall pay, or cause to be paid, the Fundamental Change Repurchase Price with respect to each Security as to which the Fundamental Change Repurchase Right shall have been exercised to the Holder thereof no later than the later of the Fundamental Change Repurchase Date and the time of book-entry transfer or when such Security is surrendered to the Paying Agent together with any necessary endorsements; provided, however, that if such Fundamental Change Repurchase Date is after a Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, then the accrued and unpaid interest, if any, to, but excluding, such Interest Payment Date will be paid on such Interest Payment Date to the Holder of record of such Security at the Close of Business on such Record Date and the Fundamental Change Repurchase Price shall not include any accrued and unpaid interest.

(d) The Company shall, in accordance with Section 2.14, deposit with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on the Fundamental Change Repurchase Date, sufficient to pay the Fundamental Change Repurchase Price upon Repurchase Upon Fundamental Change for all of the Securities that are to be repurchased by the Company on such Fundamental Change Repurchase Date pursuant to a Repurchase Upon Fundamental Change. The Paying Agent shall return to the Company, as soon as practicable, any money not required for that purpose.

(e) Once the Fundamental Change Notice and the Repurchase Notice have been duly given in accordance with this Section 3.02, the Securities to be repurchased pursuant to a Repurchase Upon Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable

in accordance herewith, and, on and after such date (unless there shall be a Default in the payment of the Fundamental Change Repurchase Price), except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, such Securities shall cease to bear interest (whether or not book-entry transfer of the Securities has been made or the Securities have been delivered to the Paying Agent), and all rights of the relevant Holders of such Securities shall terminate, other than the right to receive, in accordance herewith, such consideration and any other applicable rights under those sections set forth in the proviso in Section 8.01.

(f) Securities with respect to which a Repurchase Notice has been duly delivered in accordance with this Section 3.02 may be converted pursuant to Article 10 only if such Securities are not subject to a Repurchase Notice, such Repurchase Notice has been withdrawn in accordance with this Section 3.02 or the Company defaults in the payment of the Fundamental Change Repurchase Price.

(g) If any Security shall not be paid upon book-entry transfer or surrender thereof for Repurchase Upon Fundamental Change, the principal of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal amount of such Security, and such Security shall be convertible pursuant to Article 10 if any Repurchase Notice with respect to such Security is withdrawn pursuant to this Section 3.02.

(h) Any Security that is to be submitted for Repurchase Upon Fundamental Change only in part shall be delivered pursuant to this Section 3.02 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing, with a medallion guarantee), and the Company shall promptly execute, and the Trustee shall promptly authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly submitted for Repurchase Upon Fundamental Change.

(i) Notwithstanding anything herein to the contrary, except in the case of an acceleration resulting from a Default by the Company that would be cured by the payment of the Fundamental Change Repurchase Price, there shall be no purchase of any Securities pursuant to this Section 3.02 on any date if, on such date, the principal amount of the Securities shall have been accelerated in accordance with this Indenture and such acceleration shall not have been rescinded on or prior to such date in accordance with this Indenture. The Paying Agent will promptly return to the respective Holders thereof any Securities held by it during the continuance of such an acceleration.

(j) In connection with any Repurchase Upon Fundamental Change, the Company shall, to the extent applicable (i) comply with the provisions of Rule 13e-4 and Regulation 14E under the Exchange Act, and with all other applicable laws; (ii) file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws; and (iii) otherwise comply with all applicable United States federal and state securities laws in connection with any offer by the Company to purchase the Securities.

Section 4.01. Payment of Securities. The Company shall pay all amounts due with respect to the Securities on the dates and in the manner provided in the Securities and this Indenture. All such amounts shall be considered paid on the date due if the Paying Agent holds (or, if the Company is acting as Paying Agent, the Company has segregated and holds in trust in accordance with Section 2.04) on that date money sufficient to pay the amount then due with respect to the Securities (unless there shall be a Default in the payment of such amounts to the respective Holder(s)). The Company will pay, in money of the United States that at the time of payment is legal tender for payment of public and private debts, all amounts due in cash with respect to the Securities, which amounts shall be paid (a) in the case of a Global Security, by wire transfer of immediately available funds to the account designated by the Depositary or its nominee; (b) in the case of a Physical Security that is held by a Holder of more than five million dollars ($5,000,000) in aggregate principal amount of Securities, by wire transfer of immediately available funds to the account specified by such Holder or, if such Holder does not specify an account, by mailing a check to the address of such Holder set forth in the register of the Registrar; and (c) in the case of a Physical Security that is held by a Holder of five million dollars ($5,000,000) or less in aggregate principal amount of Securities, by mailing a check to the address of such Holder set forth in the register of the Registrar.

The Company shall pay, in cash, interest on any overdue amount (including, to the extent permitted by applicable law, overdue interest) at the rate borne by the Securities.

Section 4.02. Maintenance of Office or Agency. The Company will maintain, or cause to be maintained, in The Borough of Manhattan, The City of New York, an office or agency (which may be an office of the Trustee or an Affiliate of the Trustee, Registrar) where Securities may be surrendered for registration of transfer or exchange, payment or conversion. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain, or fail to cause to maintain, any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made or served at the Corporate Trust Office of the Trustee. The Company will maintain, or cause to be maintained, in the Borough of Manhattan, The City of New York, an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served, provided that such office or agency may instead be at the principal office of the Company located in the United States.

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 in the Borough of Manhattan, The City of New York for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates the Corporate Trust Office of the Trustee as an agency of the Company in accordance with Section 2.03.

Section 4.03. Rule 144A Information and Annual Reports. (a) If at any time the Company is not subject to the reporting requirements of the Exchange Act, until such time as the Securities are no

longer Restricted Securities, the Company shall, upon request, promptly furnish to any Holder, beneficial owner or prospective purchaser of Securities or shares of Common Stock issued upon conversion of any Securities, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Securities or shares of Common Stock pursuant to Rule 144A.

(b) The Company shall provide to the Trustee a copy of each report the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act no later than the time such report is required to be filed with the SEC pursuant to the Exchange Act (after giving effect to any grace period provided by Rule 12b-25 under the Exchange Act); provided, however, that each such report will be deemed to be so provided to the Trustee if the Company files such report with the SEC through the SEC’s EDGAR database no later than the time such report is required to be filed with the SEC pursuant to the Exchange Act (taking into account any applicable grace periods provided thereunder).

(c) Delivery of such reports, information and documents to the Trustee pursuant to this Section 4.03 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 an Officer’s Certificates).

Section 4.04. Compliance Certificate. The Company shall deliver to the Trustee, within one hundred and twenty (120) calendar days after the end of each fiscal year of the Company, commencing with the fiscal year ending March 31, 2011, a certificate of two (2) or more Officers stating whether or not the signatories to such Officer’s Certificate have actual knowledge of any Default or Event of Default by the Company in performing any of its obligations under this Indenture or the Securities. If such signatories do know of any such Default or Event of Default, then such certificate shall describe the Default or Event of Default and its status.

In addition, the Company shall provide the Trustee with a copy of any Payment Blockage Notice that it receives under Article 13 hereof.

Section 4.05. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it will 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 wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture or the Securities; and the Company (in each case, to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, 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 has been enacted.

Section 4.06. Corporate Existence. Subject to Article 5, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, in accordance with its organizational documents, and the rights (charter and statutory), licenses and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right, license or franchise if in the judgment of the Board of Directors, such preservation or existence is not in the best interest of, or is not material to the conduct of, the business of the Company.

Section 4.07. Notice of Default. Within 30 days of the Company’s becoming aware of the occurrence of any Default or Event of Default, the Company shall give written notice of such Default or Event of Default, and any remedial action proposed to be taken, to the Trustee.

Section 4.08. Further Instruments and Acts. Upon request of the Trustee, the Company shall 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 4.09. Additional Interest. (a) If, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Securities (including any Securities issued pursuant to the Initial Purchasers’ option to purchase additional Securities), the Company fails to timely file any document or report that the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, as applicable (after giving effect to all applicable grace periods thereunder and other than current reports on Form 8-K), or the Securities are not otherwise freely tradable by Holders that are not the Company’s Affiliates and that were not the Company’s Affiliates within the three immediately preceding months (as a result of restrictions pursuant to U.S. securities law), the Company shall pay Additional Interest on the Securities at a rate of 0.50% per annum of the principal amount of Securities outstanding for each day during such period for which the Company’s failure to file has occurred and is continuing or the Securities are not otherwise freely tradable by Holders, other than the Company’s Affiliates or Holders that were Affiliates of the Company within the three immediately preceding months.

(b) If, and for so long as, the Security Private Placement Legend has not been removed from the Securities in accordance with Section 2.16(b) or Section 2.17, the Securities are assigned a restricted CUSIP number or the Securities are not otherwise freely tradable by Holders that are not the Company’s Affiliates and that were not the Company’s Affiliates within the three immediately preceding months (as a result of restrictions pursuant to U.S. securities laws), as of the 370th day after the last date of original issuance of the Securities (including any Securities issued pursuant to the Initial Purchasers’ option to purchase additional Securities), the Company shall pay Additional Interest on the Securities at a rate equal to 0.50% per annum of the principal amount of Securities outstanding for each day after the 370th day after the last date of original issuance of the Securities until (i) the Security Private Placement Legend has been removed in accordance with Section 2.16(b) or Section 2.17, (ii) the Securities are assigned an unrestricted CUSIP number and (iii) the Securities are otherwise freely tradable (without restrictions pursuant to U.S. securities law) by Holders other than the Company’s Affiliates or Holders that were Affiliates of the Company within the three immediately preceding months.

(c) Notwithstanding the foregoing, no Additional Interest shall accrue or be payable under this Section 4.09 for each day on which the Company makes available to Holders an effective registration statement permitting the resale of the Securities and the shares of Common Stock issuable upon conversion thereof. After the Company has made available such an effective registration statement for a period of at least two years, no further Additional Interest shall be payable under this Section 4.09.

(d) Additional Interest payable in accordance with Section 4.09(a) and Section 4.09(b) shall be payable in arrears on each Interest Payment Date for the Securities following accrual in the same manner as regular interest on the Securities.

(e) In the event that the Company is required to pay Additional Interest to Holders of Securities (whether pursuant to this Section 4.09 or Section 6.02(b)), the Company shall provide written notice (“Additional Interest Notice”) to the Trustee of its obligation to pay Additional Interest no later than fifteen (15) calendar days prior to the proposed payment date for the Additional Interest. Each Additional Interest Notice shall set forth the amount of Additional Interest to be paid by the Company on such payment date. The Trustee shall not at any time be under any duty or responsibility to any Holder to determine the amount of Additional Interest, or with respect to the nature, extent or calculation of the amount of Additional Interest owed, or with respect to the method employed in such calculation of the Additional Interest.

Section 5.01. When Company May Merge, Etc. The Company shall not consolidate with, or merge with or into, or sell, transfer, lease, convey or otherwise dispose of all or substantially all of the consolidated property or assets of the Company to another Person, whether in a single transaction or series of related transactions, unless (i) the Company is the continuing corporation or such other Person is a corporation organized and existing under the laws of the United States of America, any state of the United States of America or the District of Columbia, and such other corporation assumes by supplemental indenture all of the obligations of the Company under the Securities and this Indenture and (ii) immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall exist.

For purposes of this Section 5.01, the sale, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of one or more Subsidiaries of the Company to another Person, which properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties or assets of the Company on a consolidated basis, shall be deemed to be the sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated properties or assets of the Company to another Person.

The Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officer’s Certificate to the foregoing effect and an Opinion of Counsel (which may rely upon such Officer’s Certificate as to the absence of Defaults and Events of Default) stating that the proposed transaction and such supplemental indenture will, upon consummation of the proposed transaction, comply with this Indenture.

Section 5.02. Successor Substituted. In case of any such consolidation, merger or any sale, transfer, lease, conveyance or other disposition of all or substantially all of the consolidated property or assets of the Company and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and accrued and unpaid interest on all of the Securities, the due and punctual payment of the Fundamental Change Repurchase Price with respect to all Securities repurchased on each Fundamental Change Repurchase Date, the due and punctual delivery or payment, as the case may be, of any consideration due upon conversion of the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture and the Securities to be performed by the Company, such successor Person shall succeed to and be substituted for the Company, with the same effect as if it had been named herein as the party of the first part. Such successor Person thereupon may cause to be signed, and may issue either in its own name or in the

name of the Company any or all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the order of such successor Person instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Securities that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Securities that such successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Securities had been issued at the date of the execution hereof. In the event of any such consolidation, merger or any sale, transfer, conveyance or other disposition (but not in the case of a lease), upon compliance with this Article 5 the Person named as the “Company” in the first paragraph of this Indenture or any successor that shall thereafter have become such in the manner prescribed in this Article 5 may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor and maker of the Securities and its obligations under this Indenture shall terminate.

In case of any such consolidation, merger or any sale, transfer, lease, conveyance or other disposition, such changes in phraseology and form (but not in substance) may be made in the Securities thereafter to be issued as may be appropriate.

(a) the Company fails to pay the principal of any Security when due, whether on the Maturity Date, on a Fundamental Change Repurchase Date with respect to a Fundamental Change, upon acceleration or otherwise (whether or not such payment is prevented by Article 13);

(b) the Company fails to pay an installment of interest on any Security when due, if the failure continues for thirty (30) days after the date when due (whether or not such payment is prevented by Article 13);

(c) the Company fails to satisfy its conversion obligations upon exercise of a Holder’s conversion rights pursuant hereto and such failure continues for a period of five (5) Business Days;

(e) the Company fails to comply with any other term, covenant or agreement set forth in the Securities or this Indenture and such failure continues for the period, and after the notice, specified in the last paragraph of this Section 6.01;

(f) the Company or any of its Subsidiaries defaults in the payment when due, after the expiration of any applicable grace period, of principal of, or premium, if any, or interest on, indebtedness for money borrowed, in the aggregate principal amount then outstanding of fifteen million dollars ($15,000,000) or more, or the acceleration of indebtedness of the Company or any of its Subsidiaries for money borrowed in such aggregate principal amount or more so that it becomes due and payable before the date on which it would otherwise become due and payable, if such default

is not cured or waived, or such acceleration is not rescinded for the period, and after the notice, specified in the last paragraph of this Section 6.01;

(g) the Company or any of its Subsidiaries fails, within sixty (60) days, to pay, bond or otherwise discharge any final, non-appealable judgments or orders for the payment of money the total uninsured amount of which for the Company or any of its Subsidiaries exceeds fifteen million dollars ($15,000,000), which are not stayed on appeal;

(h) the Company or any of its Significant Subsidiaries or any group of Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either:

(ii) consents to the entry of an order for relief against it in an involuntary case,

(iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, or

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

(i) is for relief against the Company or any of its Significant Subsidiaries or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company in an involuntary case or proceeding, or adjudicates the Company or any of its Significant Subsidiaries or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company insolvent or bankrupt,

(ii) appoints a Custodian of the Company or any of its Significant Subsidiaries or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company for all or substantially all of the consolidated property of the Company or any such Significant Subsidiary or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company, as the case may be, or

(iii) orders the winding up or liquidation of the Company or any of its Significant Subsidiaries or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company,

and, in the case of each of the foregoing clauses (i), (ii) and (iii) of this Section 6.01(i), the order or decree remains unstayed and in effect for at least thirty (30) consecutive days.

A Default under clause (e) or (f) above shall not be an Event of Default until (A) the Trustee notifies the Company in writing, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee in writing, of the Default and (B) the Default is not cured within sixty (60) days in the case of clause (e), or within thirty (30) days in the case of clause (f), after receipt of such notice. Such notice must specify the

Default, demand that it be remedied and state that the notice is a “Notice of Default.” If the Holders of at least twenty five percent (25%) in aggregate principal amount of the outstanding Securities request the Trustee to give such notice on their behalf, the Trustee shall do so. When a Default is cured, it ceases to exist for all purposes under this Indenture.

Section 6.02. Acceleration. (a) If an Event of Default (excluding an Event of Default specified in Section 6.01(h) or (i) with respect to the Company, but including an Event of Default specified in Section 6.01(h) or (i) solely with respect to a Significant Subsidiary of the Company or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) has occurred and is continuing, either the Trustee, by written notice to the Company, or the Holders of at least twenty five percent (25%) in aggregate principal amount of the Securities then outstanding, by written notice to the Company and the Trustee, may declare the Securities to be immediately due and payable in full. Upon such declaration, the principal of, and any accrued and unpaid interest on, all Securities shall be due and payable immediately. If an Event of Default specified in Section 6.01(h) or (i) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(h) or (i) solely with respect to a Significant Subsidiary of the Company or any group of its Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the principal of, and accrued and unpaid interest on, all the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by written notice to the Trustee may rescind or annul an acceleration and its consequences if (i) the rescission would not conflict with any order or decree, (ii) all existing Events of Default, except the nonpayment of principal or interest that has become due solely because of the acceleration, have been cured or waived and (iii) all amounts due to the Trustee under Section 7.06 have been paid.

(b) Notwithstanding the foregoing, for the first 180 days immediately following an Event of Default relating to failure to comply with Section 4.03(b) (which will be the 61st day after written notice is provided to the Company of the Default pursuant to the last paragraph of Section 6.01, unless such failure is cured or waived prior to such 61st day), the sole remedy for any such Event of Default shall, at the Company’s election, be the accrual of Additional Interest on the Securities at a rate per year equal to (i) 0.25% of the outstanding principal amount of Securities for the first 90 days following the occurrence of such Event of Default and (ii) 0.50% of the outstanding principal amount of Securities for the next 90 days after the first 90 days following the occurrence of such Event of Default, in each case, payable in the same manner and at the same time as the stated interest payable on the Securities. Such Additional Interest shall accrue on all outstanding Securities from, and including, the date on which such Event of Default first occurs to, and including, the 180th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On and after the 181st day immediately following an Event of Default relating to a failure to comply with Section 4.03(b), if the Company elected to pay Additional Interest pursuant to this Section 6.02(b) such Additional Interest will cease to accrue and, if such Event of Default has not been cured or waived prior to such 181st day, the Securities may be accelerated by the Holders or the Trustee as provided above. If Additional Interest is accruing and payable pursuant to either of Section 4.09(a) or Section 4.09(b) and the Company has elected that the accrual of Additional Interest be the sole remedy for any such Event of Default, no Additional Interest shall be payable pursuant to this Section 6.02(b) for so long as Additional Interest is also accruing and payable as described under either of Section 4.09(a) or Section 4.09(b) and, for the avoidance of doubt, if the Company elected to pay Additional Interest pursuant to this Section 6.02(b), the Securities will not be subject to

acceleration as provided above on account of such Event of Default until the 181st day immediately following such Event of Default (and shall not be subject to acceleration as provided above on account of such Event of Default if such Event of Default is cured or waived on or prior to the 180th day thereafter).

Section 6.03. Other Remedies. Notwithstanding any other provision of this Indenture, if an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture.

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. All remedies are cumulative.

Section 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding may, by notice to the Trustee, waive any past Default or Event of Default and its consequences, other than a Default or Event of Default (a) in the payment of the principal of, or interest on, any Security, or in the payment of the Fundamental Change Repurchase Price, (b) arising from a failure by the Company to convert any Securities in accordance with this Indenture or (c) in respect of any provision of this Indenture or the Securities which, under Section 9.02, cannot be modified or amended without the consent of the Holder of each outstanding Security affected. When a Default or an Event of Default is waived, it is cured and ceases to exist for all purposes under this Indenture.

Section 6.05. 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, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to it; provided that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

Section 6.06. Limitation on Suits. Except with respect to any proceeding instituted in accordance with Section 6.07, a Holder shall not have any right to institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under this Indenture unless:

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

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

(c) the Holder or Holders offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense to or of the Trustee in connection with pursuing such remedy; and

(d) the Trustee fails to comply with the request within sixty (60) days after receipt of such notice, request and offer of indemnity, and during such sixty (60) day period, the Holders of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction that is inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder.

Section 6.07. Rights of Holders to Receive Payment and to Convert Securities. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of all amounts (including any principal, interest or the Fundamental Change Repurchase Price) due with respect to the Securities, on or after the respective due dates as provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder.

In addition, notwithstanding any other provision of this Indenture, the right of any Holder to convert a Security in accordance with this Indenture, or to bring suit for the enforcement of such right, shall not be impaired or affected without the consent of the Holder.

Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) has occurred and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest.

Section 6.09. 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, any predecessor Trustee and the Holders allowed in any judicial proceedings relative to the Company or its creditors or properties.

The Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any 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 the Trustee any amount due 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 7.06.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder 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 6.10. Priorities. If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any payment by it to Holders pursuant to this Section 6.10. At least fifteen (15) days before each such record date, the Trustee shall mail to each Holder and the Company a written notice that states such record date and payment date and the amount of such payment.

Section 6.11. 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 other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than ten percent (10%) in aggregate principal amount of the outstanding Securities.

Section 7.01. Duties of Trustee. (a) If an Event of Default 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 their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of his or her own affairs.

(i) the Trustee need perform only those duties that are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith, willful misconduct or negligence 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; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions 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).

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

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

(ii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to the provisions of this Section 7.01.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee shall be segregated from other funds as directed in writing by the Company or as required by law and shall be invested by the Trustee pursuant to the written instructions of the Company reasonably satisfactory to the Trustee.

(f) 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, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

Section 7.02. Rights of Trustee. (a) Subject to Section 7.01, the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document; if, however, the Trustee shall determine to make such further inquiry or investigation, it shall be entitled during normal business hours to examine the relevant books, records and premises of the Company, personally or by agent or attorney upon reasonable prior notice, 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.

(b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate and/or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel.

(c) Any request or direction of the Company mentioned herein shall be sufficiently evidenced by a Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution.

(d) The Trustee may consult with counsel of its own selection, and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(e) The Trustee may act through agents or attorneys and shall not be responsible for the misconduct or negligence of any agent or attorney appointed with due care.

(f) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its discretion, rights or powers conferred upon it by this Indenture; provided that the Trustee’s action does not constitute willful misconduct or negligence.

(g) Except with respect to Section 4.01, the Trustee shall have no duty to inquire as to the performance of the Company with respect to the covenants contained in Article 4. In addition, the Trustee shall not be deemed to have knowledge of an Event of Default except (i) any Default or Event of Default occurring pursuant to Sections 6.01(a) or (b) or (ii) any Default or Event of Default

of which a Responsible Officer of the Trustee who shall have direct responsibility for the administration of this Indenture shall have received written notification or obtained actual knowledge. Delivery of reports, information and documents to the Trustee under Article 4 (other than Sections 4.04 and 4.07) is for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely on Officer’s Certificates). The Trustee shall have no duty to inquire as to the performance of the Company with respect to the subordination requirements in Article 13.

(h) Subject to Section 7.01(a), the Trustee shall be under no obligation to exercise any of the rights or powers vested by this Indenture at the request or demand of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or demand.

(i) 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, and each agent, custodian and other Person employed to act hereunder.

(j) The Trustee may request that the Company deliver an Officer’s Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer’s Certificate may be signed by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded.

(k) With respect to the lenders or holders of Specified Senior Indebtedness, the Trustee undertakes to perform or to observe only such duties as are specifically set forth in Article 13, and no implied covenants or obligations with respect to the lenders or holders of Specified Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the lenders or holders of Specified Senior Indebtedness.

Section 7.03. 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 any of its Affiliates with the same rights the Trustee would have if it were not Trustee. Any Securities Agent may do the same with like rights. The Trustee, however, must comply with Sections 7.09.

Section 7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities; the Trustee shall not be accountable for the Company’s use of the proceeds from the Securities; and the Trustee shall not be responsible for any statement in the Securities other than its certificate of authentication.

Section 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of this Indenture, or as to which a Responsible Officer of the Trustee who shall have direct responsibility for the administration of this Indenture shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within thirty (30) days after receipt of such notice or after acquiring such

knowledge, as applicable, unless such Default or Event of Default has been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment or delivery of any amounts due (including principal, interest, the Fundamental Change Repurchase Price or the consideration due upon conversion) with respect to any Security, the Trustee may withhold such notice if, and so long as it in good faith determines that, withholding such notice is in the best interests of Holders.

Section 7.06. Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its services as shall be agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it pursuant to, and in accordance with, any provision hereof, except for any such expenses as shall have been caused by the Trustee’s own negligence, bad faith or willful misconduct. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s agents and counsel. The Trustee shall provide the Company with reasonable notice of any expense not in the ordinary course of business.

The Company shall indemnify each of the Trustee, each predecessor Trustee and their respective agents for, and hold each of them harmless against, any and all loss, liability, damage, claim or expense (including the reasonable fees and expenses of counsel and taxes other than those based upon the income of the Trustee) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder, including, without limitation, under Article 13, or in connection with enforcing the provisions of this Section 7.06, including the reasonable costs and expenses of defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers and duties hereunder. The Company need not pay for any settlement made without its consent. The Trustee shall notify the Company promptly of any claim for which it may seek indemnification; provided that failure to give such notice shall not relieve the Company of its obligations under this Section 7.06. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s negligence, bad faith or willful misconduct; provided that, for the avoidance of doubt, the payment or delivery by the Trustee to the Company, the Holders or any other Person of money or assets to which any holder or lender of Specified Senior Indebtedness shall be entitled by virtue of Article 13 less than three (3) Business Days after the Trustee receives a Payment Blockage Notice shall not, solely on account of the Trustee’s having received such Payment Blockage Notice less than three (3) Business Days prior to the time of such payment or delivery, constitute negligence for the purposes of this Section 7.06.

The Company’s payment obligations to the Trustee in this Section 7.06 are not subject to the subordination provisions in Article 13.

To secure the Company’s payment obligations in this Section 7.06, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay amounts due on particular Securities.

The indemnity obligations of the Company with respect to the Trustee provided for in this Section 7.06 shall survive any resignation or removal of the Trustee and any termination of this Indenture.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.07. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.07.

The Trustee may resign by so notifying the Company in writing thirty (30) days prior to such resignation. 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 in writing and may appoint a successor Trustee with the Company’s consent. The Company may remove the Trustee if:

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 a successor Trustee does not take office within thirty (30) days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company’s expense), the Company or the Holders of at least ten percent (10%) in aggregate principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.09, the Company or any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

Section 7.08. Successor Trustee by Merger, Etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee, if such successor corporation is otherwise eligible hereunder.

Section 7.09. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that (i) is an entity organized and doing business under the laws of the United States of America or of any state thereof or the District of Columbia, (ii) is subject to supervision or examination by federal

or state authorities and (iii) has a combined capital and surplus of at least $50 million as set forth in its most recent published annual report of condition.

Section 8.01. Termination of the Obligations of the Company. This Indenture shall cease to be of further effect, and the Trustee shall execute instruments acknowledging satisfaction and discharge of this Indenture, if (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 2.07) have been delivered to the Trustee for cancellation or (ii) all outstanding Securities have become due and payable at their scheduled maturity, upon conversion or upon Repurchase Upon Fundamental Change, and in either case the Company irrevocably deposits, prior to the applicable due date, with the Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) cash or, in the case of conversion, shares of Common Stock (and cash in lieu of any fractional shares) sufficient to satisfy all obligations due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07) on the Maturity Date, the relevant settlement date of any conversion or the Fundamental Change Repurchase Date, as the case may be; (b) the Company pays to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event of Default with respect to the Securities shall exist on the date of such deposit under clause (a)(ii) above; (d) such deposit under clause (a)(ii) above shall not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture; and (e) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for herein relating to the satisfaction and discharge of this Indenture have been complied with; provided, however, that Sections 2.03, 2.04, 2.05, 2.08, 4.01, 4.02, 4.05, 7.06, 7.07, Section 7.08, 7.09, Section 14.04, 14.08 and 14.13, and Articles 8 and 13 shall survive any discharge of this Indenture until such time as the Securities have been paid in full and there are no Securities outstanding; provided further, however, that Section 7.06 shall also survive after the Securities are paid in full and there are no Securities outstanding.

Section 8.02. Application of Trust Money. The Trustee shall hold in trust all money deposited with it pursuant to Section 8.01 and shall apply such deposited money through the Paying Agent and in accordance with this Indenture to the payment of amounts due on the Securities.

Section 8.03. Repayment to Company. The Trustee and the Paying Agent shall promptly notify the Company of, and pay to the Company upon the request of the Company, any excess money held by them at any time. The Trustee or the Paying Agent, as the case may be, shall provide written notice to the Company of any money that has been held by it and has, for a period of two (2) years, remained unclaimed for the payment of the principal of, or any accrued and unpaid interest on, the Securities. The Trustee and the Paying Agent shall pay to the Company upon the written request of the Company any money held by them for the payment of the principal of, or any accrued and unpaid interest on, the Securities that remains unclaimed for two (2) years; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may, at the expense of the Company, cause to be published (in no event later than five (5) days after the Company requests repayment) once in a newspaper of general circulation in the City of New York or cause to be mailed to each Holder, notice stating that such money remains unclaimed and that, after a date specified therein, which shall not be less than thirty (30) days from the date of such publication or mailing, any unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to the money must look to the Company for

payment as general creditors, subject to applicable law, and all liability of the Trustee and the Paying Agent with respect to such money and payment shall, subject to applicable law, cease.

Section 8.04. Reinstatement. If the Trustee or Paying Agent is unable to apply any money in accordance with Sections 8.01 and 8.02 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Sections 8.01 and 8.02 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Sections 8.01 and 8.02; provided, however, that if the Company has made any payment of amounts due with respect to any Securities because of the reinstatement of its obligations, then the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

Section 9.01. Without Consent of Holders. The Company may amend or supplement this Indenture or the Securities without notice to or the consent of any Holder:

(b) to secure the obligations of the Company in respect of the Securities or add guarantees with respect to the Securities;

(d) to comply with the provisions of any securities depositary, including DTC, clearing agency, clearing corporation or clearing system, or the requirements of the Trustee or the Registrar, relating to transfers and exchanges of the Securities pursuant to this Indenture;

(e) to add to the covenants of the Company described in this Indenture for the benefit of Holders or to surrender any right or power conferred upon the Company;

(f) to make provision with respect to adjustments to the Conversion Rate as required by this Indenture or to increase the Conversion Rate in accordance with this Indenture; or

(g) to comply with the requirement of the SEC in connection with the qualification of this Indenture under the TIA.

In addition, the Company and the Trustee may enter into a supplemental indenture without the consent of Holders of the Securities to (i) cure any ambiguity, defect, omission or inconsistency in this Indenture in a manner that does not, individually or in the aggregate with all other changes, adversely affect the rights of any Holder in any respect or (ii) to conform the Indenture or the Securities to the description thereof contained in the Offering Memorandum under the heading “Description of the Notes,” as supplemented by the related pricing term sheet.

Section 9.02. With Consent of Holders. The Company may amend or supplement this Indenture or the Securities with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities (including, without limitation, consents obtained from Holders in connection with a purchase of, or tender or exchange offer for, Securities). Subject to Sections 6.04 and 6.07, the Holders of a majority in aggregate principal amount of the outstanding Securities may, by written notice to the Trustee, waive by consent (including, without limitation, consents obtained from Holders in connection with a purchase of, or tender or exchange offer for, Securities) compliance by the Company with any provision of this Indenture or the Securities without notice to any other Holder. Notwithstanding the foregoing or anything herein to the contrary, without the consent of the Holder of each outstanding Security affected, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not:

(a) change the stated maturity of the principal of, or the payment date of any installment of interest on, any Security;

(d) impair the right to institute suit for the enforcement of any delivery or payment on, or with respect to, or due upon the conversion of, any Security;

(e) modify, in a manner adverse to Holders, the provisions with respect to the right of Holders pursuant to Section 3.02 to require the Company to repurchase Securities upon the occurrence of a Fundamental Change;

(f) adversely affect the right of Holders to convert Securities in accordance with Article 10;

(g) reduce the percentage in aggregate principal amount of outstanding Securities whose Holders must consent to a modification to or amendment of any provision of this Indenture or the Securities;

(h) modify the provisions of this Indenture with respect to modification and waiver (including waiver of a Default or an Event of Default), except to increase the percentage required for modification or waiver or to provide for the consent of each affected Holder; or

(i) make any change to Article 13 if such change would adversely affect the rights of Holders.

Promptly after an amendment, supplement or waiver under Section 9.01 or this Section 9.02 becomes effective, the Company shall mail, or cause to be mailed, to Holders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to mail such notice shall not in any way impair or affect the validity of such amendment, supplement or waiver.

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

Section 9.03. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective.

After an amendment, supplement or waiver becomes effective with respect to the Securities, it shall bind every Holder unless such amendment, supplement or waiver makes a change that requires, pursuant to Section 9.02, the consent of each Holder affected. In that case, the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and, provided that notice of such amendment, supplement or waiver is reflected on a Security that evidences the same debt as the consenting Holder’s Security, every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

Nothing in this Section 9.03 shall impair the Company’s rights pursuant to Section 9.01 to amend this Indenture or the Securities without the consent of any Holder in the manner set forth in, and permitted by, such Section 9.01.

Section 9.04. Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

Section 9.05. Trustee Protected. The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article 9; provided, however, that the Trustee need not sign any amendment, supplement or waiver authorized pursuant to this Article 9 that adversely affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively rely upon an Opinion of Counsel as to legal matters and an Officer’s Certificate as to factual matters that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture.

Section 9.06. Effect of Supplemental Indentures. Upon the due execution and delivery of any supplemental indenture in accordance with this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes, and, except as set forth in Sections 9.02 and 9.03, every Holder of Securities shall be bound thereby.

Section 10.01. Conversion Privilege. (a) Subject to the limitations of Section 3.02 and Section 10.02 and the settlement provisions of Section 10.15(c), the Securities shall be convertible at any time prior to the Close of Business on the Business Day immediately preceding the Maturity

Date into shares of Common Stock and cash in lieu of fractional shares of Common Stock as described in Section 10.02 and in accordance with this Article 10.

(b) A Holder may convert a portion of the principal amount of a Security if such portion is $1,000 principal amount or an integral multiple of $1,000 principal amount. Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of such Security.

Section 10.02. Conversion Procedure and Payment Upon Conversion. (a) To convert its Security, a Holder of a Physical Security must (i) complete and manually sign the Conversion Notice, with appropriate signature guarantee, or facsimile of the Conversion Notice and deliver the completed Conversion Notice to the Conversion Agent, (ii) surrender the Security to the Conversion Agent, (iii) furnish appropriate endorsements and transfer documents if required by the Registrar or Conversion Agent, (iv) pay all transfer or similar taxes if required pursuant to Section 10.04 and (v) pay funds equal to interest payable in on the next Interest Payment Date required by Section 10.02(c). If a Holder holds a beneficial interest in a Global Security, to convert such Security, the Holder must comply with clauses (iv) and (v) above and the Depositary’s procedures for converting a beneficial interest in a Global Security.

Upon conversion of a Holder’s Security, the Company shall deliver to each converting Holder, through the Conversion Agent, a number of shares of Common Stock equal to (i) (A) the aggregate principal amount of Securities to be converted, divided by (B) $1,000, multiplied by (ii) the Conversion Rate in effect on the relevant Conversion Date (provided that the Company shall deliver cash in lieu of fractional shares as described in Section 10.03). Settlement shall occur on the third Business Day immediately following the relevant Conversion Date, unless such Conversion Date occurs on or following November 1, 2015, in which case settlement shall occur on the Maturity Date.

(b) Each conversion shall be deemed to have been effected as to any Securities surrendered for conversion at the Close of Business on the applicable Conversion Date, and the Person in whose name the shares of Common Stock shall be issuable upon such conversion shall become the holder of record of such shares as of the Close of Business on such Conversion Date. Prior to such time, a Holder receiving shares of Common Stock upon conversion shall not be entitled to any rights relating to such shares of Common Stock, including, among other things, the right to vote and receive dividends and notices of shareholder meetings. On and after the Close of Business on the Conversion Date with respect to a conversion of a Security pursuant hereto, all rights of the Holder of such Security shall terminate, other than the right to receive the consideration deliverable or payable upon conversion of such Security as provided herein and accrued but unpaid interest, if any, on such Security as provided herein.

(c) Except as provided in the Securities or in this Article 10, no payment or adjustment will be made for accrued interest on a converted Security, and accrued interest, if any, will be deemed to be paid by the consideration paid to the Holder upon conversion. Such accrued interest, if any, shall be deemed to be paid in full rather than cancelled, extinguished or forfeited. If any Holder surrenders a Security for conversion after the Close of Business on the Record Date for the payment of an installment of interest but prior to the Open of Business on the next Interest Payment Date, then, notwithstanding such conversion, the full amount of interest payable with respect to such Security on such Interest Payment Date shall be paid on such Interest Payment Date to the Holder of record of such Security at the Close of Business on such Record Date; provided, however, that such Security, when surrendered for conversion, must be accompanied by payment in cash to the Conversion Agent

on behalf of the Company of an amount equal to the full amount of interest payable on such Interest Payment Date on the Security so converted; provided further, however, that such payment to the Conversion Agent described in the immediately preceding proviso in respect of a Security surrendered for conversion shall not be required with respect to a Security that (i) is surrendered for conversion after the Close of Business on the Record Date immediately preceding the Maturity Date or (ii) is surrendered for conversion after the Close of Business on a Record Date for the payment of an installment of interest and on or prior to the Open of Business on the related Interest Payment Date, where, pursuant to Section 3.02, the Company has specified, with respect to a Fundamental Change, a Fundamental Change Repurchase Date that is after such Record Date but on or prior to such Interest Payment Date; provided further that, if the Company shall have, prior to the Conversion Date with respect to a Security, defaulted in a payment of interest on such Security, then in no event shall the Holder of such Security who surrenders such Security for conversion be required to pay such defaulted interest or the interest that shall have accrued on such defaulted interest pursuant to Section 2.12 or otherwise (it being understood that nothing in this Section 10.02(c) shall affect the Company’s obligations under Section 2.12).

(d) If a Holder converts more than one Security at the same time, the full number of shares of Common Stock issuable upon such conversion (and, as a result, the amount of cash deliverable in lieu of any fractional share of Common Stock) shall be based on the total principal amount of all Securities converted.

(e) Upon surrender of a Security that is converted in part, the Trustee shall authenticate for the Holder a new Security equal in principal amount to the unconverted portion of the Security surrendered.

(f) If the last day on which a Security may be converted is a Legal Holiday in a place where a Conversion Agent is located, the Security may be surrendered to that Conversion Agent on the next succeeding day that is not a Legal Holiday.

Section 10.03. Cash in Lieu of Fractional Shares. The Company will not issue a fractional share of Common Stock upon conversion of a Security. Instead, the Company shall pay cash in lieu of fractional shares based on the Closing Sale Price of the Common Stock on the applicable Conversion Date (or, if such Conversion Date is not a Trading Day, the Closing Sale Price of the Common Stock on the Trading Day immediately preceding such Conversion Date).

Section 10.04. Taxes on Conversion. If a Holder converts its Security, the Company shall pay any documentary, stamp or similar issue or transfer tax or duty due on the issue, if any, of Common Stock upon the conversion. However, such Holder shall pay any such tax or duty that is due because such shares are issued in a name other than such Holder’s name. The Conversion Agent may refuse to deliver a certificate representing the Common Stock to be issued in a name other than such Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax or duty which will be due because such shares are to be issued in a name other than such Holder’s name.

Section 10.05. Company to Provide Common Stock. The Company shall at all times reserve out of its authorized but unissued Common Stock or Common Stock held in its treasury enough shares of Common Stock to permit the conversion, in accordance herewith, of all of the Securities (assuming, for such purposes, that at the time of computation of such number of shares, all such Securities would be converted by a single Holder). The shares of Common Stock due upon

conversion of a Global Security shall be delivered by the Company in accordance with the Depositary’s customary practices.

All shares of Common Stock issued upon conversion of the Securities shall be validly issued, fully paid and non-assessable and shall be free of preemptive or similar rights and free of any lien or adverse claim that arises from the action or inaction of the Company.

The Company shall comply with all securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities and shall list such shares on each national securities exchange or automated quotation system on which the shares of Common Stock are listed on the applicable Conversion Date.

Section 10.06. Adjustment of Conversion Rate. The Conversion Rate shall be subject to adjustment from time to time, without duplication, upon the occurrence of any of the following events:

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

Any adjustment made under this Section 10.06(a) shall become effective immediately after the Close of Business on the record date for such dividend or distribution, or immediately after the Open of Business on the effective date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this Section 10.06(a) is declared but not so paid or made, then the Conversion Rate shall be immediately readjusted, effective as of the date the

Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company distributes to all or substantially all holders of the Common Stock any rights, options or warrants entitling them, for a period expiring not more than sixty (60) days immediately following the record date of such distribution, to purchase or subscribe for shares of Common Stock, at a price per share less than the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of announcement for such distribution, the Conversion Rate shall be increased based on the following formula:

Any increase made under this Section 10.06(b) shall be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the Close of Business on the record date for such distribution. To the extent that shares of Common Stock are not delivered after expiration of such rights, options or warrants, the Conversion Rate shall be readjusted, effective as of the date of such expiration, to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such record date for such distribution had not occurred.

In determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such average of the Closing Sale Prices for the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the date of

announcement for such distribution, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. Except in the case of a readjustment of the Conversion Rate pursuant to the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(b).

(c) If the Company distributes shares of its Capital Stock, evidences of its indebtedness or other of its assets, securities or property or rights, options or warrants to acquire its Capital Stock or other securities, to all or substantially all holders of Common Stock, but excluding (i) dividends or distributions as to which an adjustment was effected pursuant to Section 10.06(a) or Section 10.06(b), (ii) dividends or distributions paid exclusively in cash as to which an adjustment was effected pursuant to Section 10.06(d), and (iii) Spin-Offs to which the provisions set forth in the latter portion of this Section 10.06(c) shall apply (any of such shares of Capital Stock, indebtedness or other assets, securities or property or rights, options or warrants to acquire its Capital Stock or other securities, the “Distributed Property”), then, in each such case the Conversion Rate shall be increased based on the following formula:

If the Board of Directors determines “FMV” for purposes of this Section 10.06(c) 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 Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading Day period ending on the Trading Day immediately preceding the Ex Date for such distribution.

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than the “SP₀” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as the holders of the Common Stock, the amount and kind of Distributed

Property that such Holder would have received if such Holder had owned a number of shares of Common Stock equal to the Conversion Rate in effect on the record date for such distribution.

Any increase made under the portion of this Section 10.06(c) above shall become effective immediately after the Close of Business on the record date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to make such distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this Section 10.06(c) where there has been a payment of a dividend or other distribution on the Common Stock of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company, where such Capital Stock or similar equity interest is listed or quoted (or will be listed or quoted upon consummation of the transaction) on a U.S. national securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula:

The increase to the Conversion Rate under the preceding paragraph shall be given effect immediately after the Close of Business on the last Trading Day of the Valuation Period; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the Valuation Period, the reference within the portion of this Section 10.06(c) related to Spin-Offs to ten (10) consecutive Trading Days shall be deemed replaced with such lesser number of consecutive Trading Days as have elapsed between the Ex Date for such Spin-Off and the relevant Conversion Date, except that if such Conversion Date occurs on or after the Ex Date for the Spin-Off and on or prior to the record date for the Spin-Off and the converting Holder would be treated as the record holder of shares of the Common Stock as of the related Conversion Date as described under Section 10.02(b) based on an adjusted Conversion Rate for such Ex Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, the Conversion Rate adjustment for such Ex Date will not be made for such converting Holder and such Holder shall be treated as if such Holder were the record owner of the shares of the Common Stock on an un-adjusted basis and participate in the Spin-Off.

Subject in all respects to Section 10.14, rights, options or warrants distributed by the Company to all holders of its Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Common Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common Stock, shall be deemed not to have been distributed for purposes of this Section 10.06(c) (and no adjustment to the Conversion Rate under this Section 10.06(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate shall be made under this Section 10.06(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights, options or warrants with such rights (and a termination or expiration of the existing rights, options or warrants without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Rate under this Section 10.06(c) was made, (1) in the case of any such rights, options or warrants that shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to such distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if such rights, options or warrants had not been issued.

For purposes of Section 10.06(a), Section 10.06(b) and this Section 10.06(c), any dividend or distribution to which this Section 10.06(c) is applicable that also includes one or both of:

(A) a dividend or distribution of shares of Common Stock to which Section 10.06(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 10.06(b) is applicable (the “Clause B Distribution”),

then (1) such dividend or distribution, other than the Clause A Distribution and Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 10.06(c) is applicable (the “Clause C Distribution”) and any Conversion Rate adjustment required by this Section 10.06(c) with respect to such Clause C Distribution shall then be made and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Conversion Rate adjustment required by Section 10.06(a) and Section 10.06(b) with respect thereto shall then be made, except that, if determined by the Board of Directors, the record date of the Clause A Distribution and the Clause B Distribution shall be deemed to be the record date of the Clause C Distribution and any shares of Common Stock included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the Close of Business on

the record date for such dividend or distribution, or immediately after the Open of Business on the effective date of such share split or share combination, as the case may be” within the meaning of Section 10.06(a) or “outstanding immediately prior to the Close of Business on the record date for such distribution” within the meaning of Section 10.06(b).

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of either the fourth or seventh paragraph of this Section 10.06(c), the Conversion Rate shall not be decreased pursuant to this Section 10.06(c).

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

Such increase shall become effective immediately after the Close of Business on the record date for such dividend or distribution.

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, provision shall be made for each Holder of a Security to receive, for each $1,000 principal amount of Securities it holds, at the same time and upon the same terms as holders of the Common Stock, the amount of cash such Holder would have received as if such Holder owned a number of shares of Common Stock equal to the Conversion Rate on the record date for such cash dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

Except in the case of a readjustment of the Conversion Rate pursuant to the last sentence of the immediately preceding paragraph, the Conversion Rate shall not be decreased pursuant to this Section 10.06(d).

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, if the cash and value of any other consideration included in

the payment per share of Common Stock exceeds the average of the Closing Sale Prices of the Common Stock over the ten (10) consecutive Trading-Day period commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate shall be increased based on the following formula:

The increase to the Conversion Rate under this Section 10.06(e) shall occur at the Close of Business on the tenth (10th) Trading Day immediately following, and including, the Trading Date next succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten (10) Trading Days immediately following, but excluding, the date that any such tender or exchange offer expires, references in this Section 10.06(e) to ten (10) consecutive Trading Days shall be deemed to be replaced with such lesser number of consecutive Trading Days as have elapsed between the date such tender or exchange offer expires and the relevant Conversion Date. If the Company or one of its Subsidiaries is obligated to purchase the Common Stock pursuant to any such tender or exchange offer but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the Conversion Rate shall be immediately

decreased to the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

(f) In addition to the foregoing adjustments in subsections (a), (b), (c), (d) and (e) above, the Company may, from time to time and to the extent permitted by law, increase the Conversion Rate by any amount for a period of at least twenty (20) Business Days or any longer period as may be permitted or required by law, if the Board of Directors has made a determination, which determination shall be conclusive, that such increase would be in the best interests of the Company. Such Conversion Rate increase shall be irrevocable during such period. The Company shall give notice to the Trustee and cause notice of such increase to be mailed to each Holder of Securities at such Holder’s address as the same appears on the registry books of the Registrar, at least fifteen (15) days prior to the date on which such increase commences.

(g) All calculations under this Article 10 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be. Adjustments to the Conversion Rate will be calculated to the nearest 1/10,000th.

Section 10.07. No Adjustment. The Conversion Rate shall not be adjusted for any transaction or event other than for any transaction or event described in this Article 10. Without limiting the foregoing, the Conversion Rate shall not be adjusted:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities;

(ii) upon the issuance of any shares of Common Stock, restricted stock or restricted stock units, non-qualified stock options, incentive stock options or any other options or rights (including stock appreciation rights) to purchase shares of 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;

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

(v) upon the repurchase of any shares of Common Stock pursuant to an open-market share repurchase program or other buy-back transaction that is not a tender offer or exchange offer of the nature described in Section 10.06(e);

(vi) for the sale or issuance of new shares of Common Stock or securities convertible into or exercisable for shares of Common Stock for cash, including at a price per share less than the fair market value thereof or otherwise, except as described in Section 10.06; or

No adjustment in the Conversion Rate pursuant to Section 10.06(a) through (e) shall be required until cumulative adjustments amount to one percent (1%) or more of the Conversion Rate as last adjusted (or, if never adjusted, the initial Conversion Rate); provided, however, that any adjustments to the Conversion Rate which by reason of this paragraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment to the Conversion Rate; provided further that if the Securities have been converted pursuant to Section 10.01, then, in each case, any adjustments to the Conversion Rate that have been, and at such time remain, deferred pursuant to this Section 10.07 shall be given effect, and such adjustments, if any, shall no longer be carried forward and taken into account in any subsequent adjustment to the Conversion Rate.

No adjustment to the Conversion Rate need be made pursuant to Section 10.06 for a transaction (other than for share splits or share combinations pursuant to Section 10.06(a)) if the Company makes provision for each Holder to participate in the transaction, at the same time and upon the same terms as holders of Common Stock participate in such transaction, without conversion, as if such Holder held a number of shares of Common Stock equal to the Conversion Rate in effect on the record date or effective date, as applicable, of the transaction (without giving effect to any adjustment pursuant to Section 10.06 on account of such transaction), multiplied by principal amount (expressed in thousands) of Securities held by such Holder.

Section 10.08. Other Adjustments. Whenever any provision of this Indenture requires the computation of an average of the Closing Sale Prices over a period of multiple Trading Days, the Board of Directors, in its good faith determination, shall appropriately adjust such average to account for any event requiring, pursuant hereto, an adjustment to the Conversion Rate where the effective date, ex-dividend date or expiration date of such event occurs at any time on or after the first Trading Day of such period and on or prior to the last Trading Day of such period.

Section 10.09. Adjustments for Tax Purposes. Except as prohibited by law the Company may (but is not obligated to) increase the Conversion Rate, in addition to those required by Section 10.06 hereof, as it determines to be advisable in order that any stock dividend, subdivision of shares, distribution of rights to purchase stock or securities or distribution of securities convertible into or exchangeable for stock made by the Company or to its shareholders will not be taxable to the recipients thereof or in order to avoid or diminish any such taxation.

Section 10.10. Notice of Adjustment. Whenever the Conversion Rate is adjusted, the Company shall promptly mail to Holders at the addresses appearing on the Registrar’s books a notice of the adjustment and file with the Trustee an Officer’s Certificate briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence of the correctness of such adjustment.

(a) the Company takes any action, or becomes aware of any event, that would require an adjustment in the Conversion Rate,

(b) the Company takes any action that would require a supplemental indenture pursuant to Section 10.12, or

the Company shall promptly mail to Holders at the addresses appearing on the Registrar’s books and the Trustee a written notice stating the proposed record date, Ex Date, effective date and expiration date, as applicable, of the transaction referred to in clause (a), (b) or (c) of this Section 10.11. If the transaction (A) is not a Spin-Off, but would require an adjustment to the Conversion Rate pursuant to Section 10.06(c), or (B) would require an adjustment to the Conversion Rate pursuant to Section 10.06(d), the Company will use commercially reasonable efforts to mail the notice at least 15 Business Days immediately prior to the Ex Date applicable to the transaction, and, if the transaction (A) is a Spin-Off that would require an adjustment to the Conversion Rate pursuant to Section 10.06(c) or (B) would require an adjustment to the Conversion Rate pursuant to Section 10.06(e), the Company will use commercially reasonable efforts to mail the notice at least 5 Business Days prior to the Ex Date or expiration date applicable to the transaction, as the case may be.

Section 10.12. Effect of Reclassifications, Consolidations, Mergers, Binding Share Exchanges or Sales on Conversion Privilege. If the Company:

(a) reclassifies the Common Stock (other than a change only in par value, or from par value to no par value, or from no par value to par value, or a change as a result of a subdivision or combination of Common Stock to which Section 10.06(a) applies);

(c) sells, transfers, leases, conveys or otherwise disposes of all or substantially all of the consolidated property or assets of the Company,

in each case, pursuant to which the Common Stock would be converted into or exchanged for, or would constitute solely the right to receive, cash, securities or other property (any such event, a “Merger Event”), each $1,000 principal amount of converted Securities will, from and after the effective time of such Merger Event, be convertible into the same kind, type and proportions of consideration that a holder of a number of shares of Common Stock equal to the Conversion Rate in effect immediately prior to such Merger Event would have received in such Merger Event (“Reference Property”) and, prior to or at the effective time of such Merger Event, the Company or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 9.01(a) providing for such change in the right to convert the Securities.

If the Merger Event causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), then (i) the Reference Property into which the Securities will be convertible shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one share of Common Stock. The Company shall notify Holders, the Trustee and the Conversion Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

The supplemental indenture referred to in the first sentence of this Section 10.12 shall provide for adjustments to the Conversion Rate that shall be as nearly equivalent as may be

practicable to the adjustments of the Conversion Rate provided for in this Article 10 and for the delivery of cash by the Company in lieu of fractional securities or property that would otherwise be deliverable to holders upon Conversion as part of the Reference Property, with such amount of cash determined by the Board of Directors in a manner as nearly equivalent as may be practicable to that used by the Company to determine the Closing Sale Price of the Common Stock. The provisions of this Section 10.12 shall similarly apply to successive consolidations, mergers, binding share exchanges, sales, transfers, leases, conveyances or dispositions.

The Company shall not become a party to any Merger Event unless its terms are consistent with this Section 10.12.

None of the foregoing provisions shall affect the right of a Holder to convert its Securities into shares of Common Stock (and cash in lieu of any fractional share) as set forth in Section 10.01 and Section 10.02 prior to the effective date of such Merger Event.

In the event the Company shall execute a supplemental indenture pursuant to this Section 10.12, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of Reference Property receivable by Holders of the Securities upon the conversion of their Securities after any such Merger Event and any adjustment to be made with respect thereto.

Section 10.13. Trustee’s Disclaimer. The Trustee has no duty to determine when an adjustment under this Article 10 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of the correctness of any such adjustment, and shall be protected in relying upon, the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.10 hereof. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the failure by the Company to comply with any provisions of this Article 10.

The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 10.12, but may accept as conclusive evidence of the correctness thereof, and shall be protected in relying upon, the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 10.12 hereof.

Section 10.14. Rights Distributions Pursuant to Shareholders’ Rights Plans. To the extent that the Company adopts a rights plan (i.e., a poison pill) and such plan is in effect upon conversion of any Security or a portion thereof, the Company shall make provision such that each Holder thereof shall receive, in addition to, and concurrently with the delivery of, the shares of Common Stock due upon conversion, the rights described in such plan, unless the rights have separated from the Common Stock before the time of conversion, in which case the Conversion Rate shall be adjusted at the time of separation as if the Company distributed to all holders of Common Stock, Distributed Property as described in Section 10.06(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

Section 10.15. Increased Conversion Rate Applicable to Certain Securities Surrendered in Connection with Make-Whole Fundamental Changes. (a) Notwithstanding anything herein to the contrary, the Conversion Rate applicable to each Security that is surrendered for conversion, in

accordance with this Article 10, at any time during the period (the “Make-Whole Conversion Period”) from, and including, the effective date (the “Effective Date”) of a Make-Whole Fundamental Change (which Effective Date the Company shall disclose in the written notice referred to in Section 10.15(e)) (A) to, and including, the Close of Business on the date that is thirty (30) Business Days after the later of (i) such Effective Date and (ii) the date the Company mails to Holders the relevant notice of the Effective Date or (B) if such Make-Whole Fundamental Change also constitutes a Fundamental Change, to, and including, the Close of Business on the Fundamental Change Repurchase Date corresponding to such Fundamental Change, shall be increased to an amount equal to the Conversion Rate that would, but for this Section 10.15, otherwise apply to such Security pursuant to this Article 10, plus an amount equal to the Make-Whole Applicable Increase.

(b) As used herein, “Make-Whole Applicable Increase” shall mean, with respect to a Make-Whole Fundamental Change, the amount, set forth in the following table, which corresponds to the Effective Date and the Applicable Price of such Make-Whole Fundamental Change:

(i) if the actual Applicable Price of such Make-Whole Fundamental Change is between two (2) Applicable Prices listed in the table above under the column titled “Applicable Price,” or if the actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates listed in the table above in the row immediately below the title “Effective Date,” then the Make-Whole Applicable Increase for such Make-Whole Fundamental Change shall be determined by linear interpolation between the Make-Whole Applicable Increases set forth for such higher and lower Applicable Prices, or for such earlier and later Effective Dates based on a three hundred and sixty five (365) day year, as applicable;

(ii) if the actual Applicable Price of such Make-Whole Fundamental Change is greater than $20.00 per share (subject to adjustment in the same manner as the Applicable Prices pursuant to Section 10.15(b)(iii)), or if the actual Applicable Price of such Make-Whole Fundamental Change is less than $3.27 per share (subject to adjustment in the same manner as the Applicable Prices pursuant to Section 10.15(b)(iii)), then the Make-Whole Applicable Increase shall be equal to zero (0);

(iii) if an event occurs that requires, pursuant to this Article 10 (other than solely pursuant to this Section 10.15), an adjustment to the Conversion Rate, then, on the date and at the time such adjustment is so required to be made, each Applicable Price set forth in the table above under the column titled “Applicable Price” shall be deemed to be adjusted so that such Applicable Price, at and after such time, shall be equal to the product of (A) such Applicable Price as in effect immediately before such adjustment to such Applicable Price and (B) a fraction the numerator of which is the Conversion Rate in effect immediately before such adjustment to the Conversion Rate and the denominator of which is the Conversion Rate to be in effect, in accordance with this Article 10, immediately after such adjustment to the Conversion Rate;

(iv) each Make-Whole Applicable Increase amount set forth in the table above shall be adjusted in the same manner, for the same events and at the same time as the Conversion Rate is required to be adjusted pursuant to Section 10.06 through Section 10.14; and

(v) in no event shall the Conversion Rate applicable to any Security be increased pursuant to this Section 10.15 to the extent, but only to the extent, such increase shall cause the Conversion Rate applicable to such Security to exceed 305.8103 shares per $1,000 principal amount (the “Maximum Conversion Rate”); provided, however, that the Maximum Conversion Rate shall be adjusted at the same time and in the same manner in which, and for the same events for which, the Conversion Rate is to be adjusted pursuant to this Article 10.

(c) Subject to Section 10.12, upon surrender of Securities for conversion in connection with a Make-Whole Fundamental Change, the Company shall satisfy its conversion obligation by delivering shares of Common Stock (together with cash in lieu of any fractional share) in accordance with Section 10.02; provided, however, that if at the effective time of a Make-Whole Fundamental Change described in clause (c) of the definition of Change in Control the consideration for the Common Stock is composed entirely of cash, for any conversion of Securities following the Effective Date of such Make-Whole Fundamental Change, the conversion obligation shall be calculated based solely on the Applicable Price for the transaction and shall be deemed to be an amount equal to, per $1,000 principal amount of converted Securities, the Conversion Rate (including any Make-Whole Applicable Increase), multiplied by such Applicable Price.

(d) As used herein, “Applicable Price” shall have the following meaning with respect to a Make-Whole Fundamental Change: (i) if such Make-Whole Fundamental Change is a transaction or series of transaction described in clause (c) of the definition of Change in Control and the consideration (excluding cash payments for fractional shares or pursuant to statutory appraisal rights) for shares of the Common Stock in such Make-Whole Fundamental Change consists solely of cash, then the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the cash amount paid per share of Common Stock in such Make-Whole Fundamental Change and (ii) in all other circumstances, the “Applicable Price” with respect to such Make-Whole Fundamental Change shall be equal to the average of the Closing Sale Prices per share of Common Stock for the five (5) consecutive Trading Days immediately preceding, but excluding, the Effective Date of such Make-Whole Fundamental Change, which average shall be appropriately adjusted by the Board of Directors, in its good faith determination, to account for any adjustment, pursuant hereto, to the Conversion Rate that shall become effective, or any event requiring, pursuant hereto, an adjustment

to the Conversion Rate where the record date of such event occurs, at any time during such five (5) consecutive Trading Days.

(e) The Company shall mail to each Holder, in accordance with Section 14.01, written notice of the Effective Date of the Make-Whole Fundamental Change within ten (10) days of such Effective Date. Each such notice shall also state that, in connection with such Make-Whole Fundamental Change, the Company shall increase, in accordance herewith, the Conversion Rate applicable to Securities entitled as provided herein to such increase (along with a description of how such increase shall be calculated and the time periods during which Securities must be surrendered in order to be entitled to such increase, including, without limitation, the last day of the Make-Whole Conversion Period).

(f) For avoidance of doubt, the provisions of this Section 10.15 shall not affect or diminish the Company’s obligations, if any, pursuant to Article 3 with respect to a Make-Whole Fundamental Change that also constitutes a Fundamental Change.

(g) Nothing in this Section 10.15 shall prevent an adjustment to the Conversion Rate pursuant to Section 10.06 in respect of a Make-Whole Fundamental Change.

Section 11.01. Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Securities may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action, the Holders of such specified percentage have joined therein may be evidenced (i) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, (ii) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Article 12 or (iii) by a combination of such instrument or instruments and any such record of such a meeting of Holders. Whenever the Company or the Trustee solicits the taking of any action by the Holders of the Securities, the Company or the Trustee may fix, but shall not be required to, in advance of such solicitation, a date as the record date for determining Holders entitled to take such action. The record date if one is selected shall be not more than fifteen (15) days prior to the date of commencement of solicitation of such action.

Section 11.02. Proof of Execution by Holders. Subject to the provisions of Section 7.01, Section 7.02 and Section 12.05, proof of the execution of any instrument by a Holder or its agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The holding of Securities shall be proved by the security register of the Registrar or by a certificate of the Registrar. The record of any Holders’ meeting shall be proved in the manner provided in Section 12.06.

Section 11.03. Persons Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent and any Registrar may deem the Person in whose name a Security shall be registered upon the security register of the Registrar to be, and may treat it as, the absolute owner of such Security (whether or not such Security shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any Person

other than the Company or any Registrar) for the purpose of receiving payment of or on account of the principal of and (subject to Section 2.12 and Section 4.01) accrued and unpaid interest on such Security, for conversion of such Security and for all other purposes; and neither the Company nor the Trustee nor any authenticating agent nor any Paying Agent nor any Conversion Agent nor any Registrar shall be affected by any notice to the contrary. All such payments so made to any Holder for the time being, or upon its order, shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies payable upon any such Security. Notwithstanding anything to the contrary in this Indenture or the Securities following an Event of Default, any Holder of a beneficial interest in a Global Security may directly enforce against the Company, without the consent, solicitation, proxy, authorization or any other action of the Depositary or any other Person, such Holder’s right to exchange such beneficial interest for a Physical Security in accordance with the provisions of this Indenture.

Section 12.01. Purpose of Meetings. A meeting of Holders may be called at any time and from time to time pursuant to the provisions of this Article 12 for any of the following purposes:

(a) to give any notice to the Company or to the Trustee or to give any directions to the Trustee permitted under this Indenture, or to consent to the waiving of any Default or Event of Default hereunder and its consequences, or to take any other action authorized to be taken by Holders pursuant to any of the provisions of Article 6;

Section 12.02. Call of Meetings by Trustee. The Trustee may at any time call a meeting of Holders to take any action specified in Section 12.01, to be held at such time and at such place as the Trustee shall determine. Notice of every meeting of the Holders, setting forth the time and the place of such meeting and in general terms the action proposed to be taken at such meeting and the establishment of any record date pursuant to Section 11.01, shall be mailed to Holders of such Securities at their addresses as they shall appear on the security register of the Registrar. Such notice shall also be mailed to the Company. Such notices shall be mailed not less than twenty (20) nor more than ninety (90) days prior to the date fixed for the meeting.

Any meeting of Holders shall be valid without notice if the Holders of all Securities then outstanding are present in person or by proxy or if notice is waived before or after the meeting by the Holders of all Securities outstanding, and if the Company and the Trustee are either present by duly authorized representatives or have, before or after the meeting, waived notice.

Section 12.03. Call of Meetings by Company or Holders. In case at any time the Company, pursuant to a Board Resolution, or the Holders of at least 10% in aggregate principal amount of the Securities then outstanding, shall have requested the Trustee to call a meeting of Holders, by written request setting forth in reasonable detail the action proposed to be taken at the meeting, and the Trustee shall not have mailed the notice of such meeting within twenty (20) days after receipt of such request, then the Company or such Holders may determine the time and the place for such meeting and may call such meeting to take any action authorized in Section 12.01, by mailing notice thereof as provided in Section 12.02.

Section 12.04. Qualifications for Voting. To be entitled to vote at any meeting of Holders a Person shall (a) be a Holder of one or more Securities on the record date pertaining to such meeting or (b) be a Person appointed by an instrument in writing as proxy by a Holder of one or more Securities on the record date pertaining to such meeting.

The Trustee shall, by an instrument in writing, appoint a temporary chairman of the meeting, unless the meeting shall have been called by the Company or by Holders as provided in Section 12.03, in which case the Company or the Holders calling the meeting, as the case may be, shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Holders of a majority in principal amount of the Securities represented at the meeting and entitled to vote at the meeting.

Subject to the provisions of Section 2.09, at any meeting of Holders each Holder or proxyholder shall be entitled to one vote for each $1,000 principal amount of Securities held or represented by such Holder or proxyholder, as the case may be; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not outstanding and ruled by the chairman of the meeting to be not outstanding. The chairman of the meeting shall have no right to vote other than by virtue of Securities held by it or instruments in writing as aforesaid duly designating it as the proxy to vote on behalf of other Holders. Any meeting of Holders duly called pursuant to the provisions of Section 12.02 or Section 12.03 may be adjourned from time to time by the Holders of a majority of the aggregate principal amount of Securities represented at the meeting, whether or not constituting a quorum, and the meeting may be held as so adjourned without further notice.

A

The record shall show the principal amount of the Securities voting in favor of or against any resolution. The record shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one of the duplicates shall be delivered to the Company and the other to the Trustee to be preserved by the Trustee, the latter to have attached thereto the ballots voted at the meeting.

Any record so signed and verified shall be conclusive evidence of the matters therein stated.

Section 12.07. No Delay of Rights by Meeting. Nothing contained in this Article 12 shall be deemed or construed to authorize or permit, by reason of any call of a meeting of Holders or any rights expressly or impliedly conferred hereunder to make such call, any hindrance or delay in the exercise of any right or rights conferred upon or reserved to the Trustee or to the Holders under any of the provisions of this Indenture or of the Securities.

Section 13.01. Agreement of Subordination. Any payment on the Securities, including, without limitation, payment of principal (including the Fundamental Change Repurchase Price, if applicable), interest and payments due upon conversion for any fractional share, shall be subordinated and subject in right of payment to the prior payment in full in cash, or other payment satisfactory to the lenders or holders, as the case may be, of Specified Senior Indebtedness.

Section 13.02. Payments to Holders. (a) Subject to the provisions of Section 13.04, no payment shall be made with respect to the Securities, including, without limitation, payment of principal (including the Fundamental Change Repurchase Price, if applicable), interest and payments due upon conversion for any fractional share, if:

(i) a default by the Company in the payment or prepayment of principal of or interest on, or other payment obligations due on, any Specified Senior Indebtedness occurs and is continuing (or, in the case of a default which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, specified in such Specified Senior Indebtedness); or

(ii) a default, other than a payment default as described in clause (i) above, on any Specified Senior Indebtedness occurs and is continuing that permits the lenders or holders thereof to accelerate the maturity of the such Specified Senior Indebtedness and the Company or the Trustee receives a notice that such default has occurred and is continuing (a “Payment Blockage Notice”) from an agent party to such Specified Senior Indebtedness or a lender or holder of such Specified Senior Indebtedness.

(b) Subject to the provisions of Section 13.04, if the Company or the Trustee receives any Payment Blockage Notice pursuant to clause (a)(ii) above, no subsequent Payment Blockage Notice shall be effective for purposes of this Section 13.02 unless and until at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice. No

nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Company or the Trustee (unless such default was waived, cured or otherwise ceased to exist and thereafter subsequently reoccurred) shall be, or be made, the basis for a subsequent Payment Blockage Notice.

(i) in the case of a default referred to in clause (a)(i) above, the date upon which all such payments due in respect of the relevant Specified Senior Indebtedness have been paid in full in cash or other payment satisfactory to the lenders or holders thereof; or

(ii) in the case of a default referred to in clause (a)(ii) above, the earlier of (A) the date on which such default is cured, waived or ceased to exist and (B) 179 days after the date on which the applicable Payment Blockage Notice is received, unless this Article 13 otherwise prohibits the payment or distribution at the time of such payment or distribution; provided that if such Specified Senior Indebtedness has been accelerated, the Company shall make no payments on or distributions in respect of the Securities and the Holders of the Securities shall not receive or retain any such payments or distributions until such Specified Senior Indebtedness has been paid in full in cash or other payment satisfactory to the lenders or holders thereof or such acceleration has been cured or waived.

(d) Upon any payment by the Company or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution, winding-up, liquidation or reorganization of the Company (whether voluntary or involuntary) or in the event of bankruptcy, insolvency, receivership, assignment for the benefit of creditors or similar proceedings, all amounts due or to become due upon any Specified Senior Indebtedness shall first be paid in full in cash, or other payments satisfactory to the lenders or holders thereof, before any payment is made on account of the Securities. Upon any such dissolution or winding-up or liquidation or reorganization of the Company or bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Holders of the Securities would be entitled, except for the provisions of this Article 13, shall (except as provided above) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Holders of the Securities if received by them, directly to the lenders or holders of Specified Senior Indebtedness (pro rata to such lenders or holders on the basis of the respective amounts of Specified Senior Indebtedness held by such lenders or holders, or as otherwise required by law or a court order) or the agent or trustee, as applicable, of the Specified Senior Indebtedness, to the extent necessary to pay such Specified Senior Indebtedness in full in cash, or other payment satisfactory to the lenders or holders thereof, after giving effect to any concurrent payment or distribution to or for the lenders or holders of Specified Senior Indebtedness, before any payment or distribution is made to the Holders of Securities.

(e) For purposes of this Article 13, the words, “cash, property or securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article 13 with respect to the Securities to the payment of any Specified Senior Indebtedness which may at the time be outstanding; provided that (i) such Specified Senior Indebtedness is assumed by the new corporation, if any, resulting from any reorganization or readjustment, and (ii) the rights of the lenders or holders of such

Specified Senior Indebtedness (other than leases which are not assumed by the Company or the new corporation, as the case may be) are not, without the consent of such lenders or holders, altered by such reorganization or readjustment.

(f) The consolidation of the Company with, or the merger of the Company with or into, another corporation or the liquidation or dissolution of the Company following the sale, transfer, conveyance, or other disposition of all or substantially all of the consolidated property or assets of the Company to another Person, whether in a single transaction or series of related transactions, upon the terms and conditions provided for in Article 5 shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section 13.02 if such other Person shall, as a part of such consolidation, merger, sale, transfer, conveyance or other disposition, comply with the conditions stated in Article 5.

(g) In the event of any acceleration of the Securities because of an Event of Default, no payment or distribution shall be made on the Securities, including, without limitation, payment of principal (including the Fundamental Change Repurchase Price, if applicable), interest and payments due upon conversion for any fractional share, by the Company until all Specified Senior Indebtedness has been paid in full in cash or other payment satisfactory to the lenders or holders thereof or such acceleration is rescinded in accordance with the terms of this Indenture. If the Securities are accelerated because of an Event of Default, the Company shall promptly notify the lenders or holders of Specified Senior Indebtedness of such acceleration.

(h) In the event that, notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities (including, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Holders of the Securities before any Specified Senior Indebtedness is paid in full, in cash or other payment satisfactory to the lenders or holders thereof, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory to the lenders or holders thereof, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the lenders or holders of such Specified Senior Indebtedness or the agent or trustee, as the case may be, for such Specified Senior Indebtedness, as calculated by the Company, for application to the payment of the amounts of such Specified Senior Indebtedness remaining unpaid to the extent necessary to pay the Specified Senior Indebtedness in full, in cash or other payment satisfactory to the lenders or holders thereof, after giving effect to any concurrent payment or distribution to or for the lenders or holders thereof.

(i) This Section 13.02 shall be subject to the further provisions of Section 13.04.

Section 13.03. Subrogation of the Securities. (a) Subject to the payment in full, in cash or other payment satisfactory to the lenders or holders of Specified Senior Indebtedness, the rights of the Holders of the Securities shall be subrogated to the extent of the payments or distributions made to the lenders or holders of Specified Senior Indebtedness pursuant to the provisions of this Article 13 (equally and ratably with the holders of all indebtedness of the Company which by its express terms is subordinated to all Specified Senior Indebtedness to substantially the same extent as the Securities are subordinated to all Specified Senior Indebtedness and is entitled to like rights of subrogation) to the rights of the lenders or holders of Specified Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Specified Senior Indebtedness until the payments on the Securities, including, without limitation, payment of principal (including the Fundamental Change Repurchase Price, if applicable), interest and payments

due upon conversion for any fractional share shall be paid in full in cash or other payment satisfactory to the lenders or holders of Specified Senior Indebtedness; and, for the purposes of such subrogation, no payments or distributions to the lenders or holders of Specified Senior Indebtedness of any cash, property or securities to which the Holders of Securities would be entitled except for the provisions of this Article 13, and no payment over pursuant to the provisions of this Article 13, to or for the benefit of the lenders or holders of Specified Senior Indebtedness by the Holders of Securities, shall, as between the Company, its creditors other than the lenders or holders of Specified Senior Indebtedness, and the Holders of Securities, be deemed to be a payment by the Company to or on account of the Specified Senior Indebtedness; and no payments or distributions of cash, property or securities to or for the benefit of the Holders of Securities pursuant to the subrogation provisions of this Article 13, which would otherwise have been paid to the lenders or holders of Specified Senior Indebtedness shall be deemed to be a payment by the Company to or for the account of the Securities. It is understood that the provisions of this Article 13 are and are intended solely for the purposes of defining the relative rights of the Holders of Securities, on the one hand, and the lenders or holders of Specified Senior Indebtedness, on the other hand.

(b) Nothing contained in this Article 13 or elsewhere in this Indenture is intended to or shall impair, as among the Company, its creditors other than the lenders or holders of Specified Senior Indebtedness, and the Holders of Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of Securities the principal (including the Fundamental Change Repurchase Price, if applicable), interest and payments due upon conversion for any fractional share as and when the same shall become due and payable in accordance with its terms, or is intended to or shall affect the relative rights of the Holders of Securities and creditors of the Company other than the lenders or holders of Specified Senior Indebtedness, nor shall anything herein or therein prevent the Holders of Securities from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article 13 of the lenders or holders of Specified Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

The Company or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security for which a Repurchase Notice has been delivered, and not withdrawn, in accordance with the Indenture, except the unrepurchased portion of Securities being repurchased in part.
