THE SECURITIES

Section 2.01. Form and Dating.

The Securities and the Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A, which Exhibit is incorporated in and made part of this Indenture. The Securities may include such letters, numbers or other marks of identification and such notations, legends, endorsements or changes as the Officer executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required by the Trustee, the Depositary, or as may be required to comply with any applicable law or with any rule or regulation made pursuant thereto or with any rule or regulation of any national securities exchange or automated quotation system on which the Securities may be listed or quoted, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Securities are subject. Each Security shall be dated the date of its authentication.

(a) Global Securities. All of the Securities initially being offered and sold to the Underwriters shall be issued in the form of one or more Global Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with The Bank of New York, at its Corporate Trust Office, as custodian for the depositary, The Depository Trust Company (“DTC”, and such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co. (or any successor thereto), for the accounts of participants in the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Global Securities may from time to time be increased or decreased by adjustments made on the

records of the Securities Custodian as hereinafter provided, subject in each case to compliance with the Applicable Procedures.

(b) Global Securities In General. The Global Security shall represent such of the outstanding Securities as shall be specified therein and each shall provide that it shall represent the aggregate principal amount of outstanding Securities from time to time endorsed thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, purchases or conversions of such Securities.

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary or under the Global Security, and the Depositary (including, for this purpose, its nominee) may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. None of the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or obligation to any beneficial owner in a Global Security, an Agent Member or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any Agent Member, with respect to any ownership interest in the Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities and this Indenture shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of beneficial owners in the Global Security shall be exercised only through the Depositary subject to the applicable procedures. The Trustee, the Paying Agent and the Security Registrar shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. The Trustee, the Paying Agent and the Security Registrar shall be entitled to deal with the Depositary, and any nominee thereof, that is the registered Holder of any Global Security for all purposes of this Indenture relating to such Global Security (including the payment of principal, premium, if any, and interest and additional amounts, if any, and the giving of instructions or directions by or to the owner or Holder of a beneficial ownership interest in such Global Security) as the sole Holder of such Global Security and shall have no obligations to the beneficial owners thereof. None of the Trustee, the Paying Agent or the Security Registrar shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of any such depositary, including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between the Depositary and any Agent Member or between or among the Depositary, any such Agent Member and/or any Holder or owner of a beneficial interest in such Global Security, or for any transfers of beneficial interests in any such Global Security.

Notwithstanding the foregoing, nothing herein shall (1) prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or (2) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

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

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

Section 2.02. Execution and Authentication.

(a) The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is limited to $___aggregate principal amount ($___aggregate principal amount if the Underwriters exercise their over-allotment option in full), except as provided in Sections 2.07 and 2.08.

(b) The Securities shall be executed on behalf of the Company by one of its Officers. The signatures of any of the Officers on the Securities may be manual or facsimile.

(c) Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

(d) No Security or Guarantee endorsed thereon shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

(e) The Trustee shall authenticate and make available for delivery Securities for original issue in the aggregate principal amount of $___(or up to $___if the Underwriters exercise their over-allotment option in full) upon receipt of a Company Order. The Company Order shall specify the amount of Securities to be authenticated, shall provide that all

such Securities will be represented by a Global Security and the date on which each original issue of Securities is to be authenticated.

(f) The Trustee shall act as the initial authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company.

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

Section 2.03. Registrar, Paying Agent and Conversion Agent.

The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall keep a register of the Securities and of their transfer and exchange. At the option of the Company, any payment of cash may be made by check mailed to the Holders at their addresses set forth in the register of Holders.

(b) The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, provided that the Agent may be an Affiliate of the Trustee. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company shall notify the Trustee of the name and address, and any change in the name or address, of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar, Paying Agent, Conversion Agent, or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any Affiliate of the Company may act as Paying Agent (except for the purposes of Article 9).

(c) The Company hereby initially designates The Bank of New York as Paying Agent, Registrar, Securities Custodian and Conversion Agent, and designates the Corporate Trust Office of the Trustee as the office or agency of the Company for each of the aforesaid purposes and as the office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served.

Section 2.04. Paying Agent To Hold Money In Trust.

Unless otherwise specified herein, prior to 10:00 a.m., New York City time, on each due date of the payment of principal of, or interest on, any Securities, the Company shall deposit a sum sufficient to

pay such principal or interest so becoming due. A Paying Agent shall hold in trust for the benefit of Holders of Securities or the Trustee all money held by the Paying Agent for the payment of principal of, or interest on, the Securities, and shall notify the Trustee of any failure by the Company (or any other obligor on the Securities) to make any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall, before 10:00 a.m., New York City time, on each due date of the principal of, or interest on, any Securities, segregate the money and hold it as a separate trust fund for the benefit of Holders. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee, and the Trustee may at any time during the continuance of any Default, upon written request to a Paying Agent, require such Paying Agent to pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or interest on any Security and remaining unclaimed for two years after such principal or interest has become due and payable shall promptly be paid to the Company or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; 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 once, in a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will promptly be repaid to the Company.

While any such default continues, the Trustee may require a Conversion Agent to deliver all cash and shares of Common Stock delivered by the Company to it to the Trustee. Upon payment over to the Trustee, the Conversion Agent (if other than the Company or a Subsidiary) shall have no further liability in respect of such amounts. If the Company or a Subsidiary acts as Conversion Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all cash and shares of Common Stock held by it as Conversion Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee shall serve as Conversion Agent for the Securities.

Section 2.06. Lists of Holders of Securities.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders of Securities. The Company shall furnish or cause the Registrar to furnish to the Trustee (a) semiannually, not more than 10 days after each Regular Record Date, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such Regular Record Date; and (b) at such other times as the Trustee may request in writing, within 30 days after receipt by the Company of any such request, a list of similar form and content to that in subsection (a) hereof as of a date not more than 15 days prior to the time such list is

furnished; provided, however, that if and so long as the Trustee shall be the Primary Registrar, no such list need be furnished.

Section 2.07. Transfer and Exchange.

(a) Subject to compliance with any applicable additional requirements contained in Section 2.13, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transactions are met; provided, however, that every Security presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each substantially in the form included in Exhibit A, and completed in a manner satisfactory to the Registrar and duly executed by the Holder thereof or its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.03, the Company shall execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be imposed in relation thereto; provided that this sentence shall not apply to any exchange pursuant to Section 2.11, 2.13(a), 4.02(d) or 10.06.

(b) Neither the Company, any Registrar nor the Trustee shall be required to register the transfer of or exchange any Securities or portions thereof in respect of which a Fundamental Change Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased).

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

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

(e) Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that may result from the registration of transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States federal or state securities law.

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

Section 2.08. Replacement Securities.

(a) If (1) any mutilated Security is surrendered to the Trustee, or (2) the Company and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company and the Trustee, such security or indemnity, in each case, as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and upon a Company Request the Trustee shall authenticate and deliver, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a replacement Security of like tenor and principal amount, bearing a number not contemporaneously outstanding and each Guarantor shall execute a replacement Guarantee.

(b) If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the Company pursuant to Article 3, or converted pursuant to Article 4, the Company in its discretion may, instead of issuing a new Security, pay, purchase or convert such Security, as the case may be.

(c) Upon the issuance of any new Securities under this Section 2.08, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of counsel and the Trustee) in connection therewith.

(d) Every new Security and Guarantee issued pursuant to this Section 2.08 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company and each Guarantor, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

(e) The provisions of this Section 2.08 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 2.09. Outstanding Securities.

(a) Securities outstanding (“Outstanding”) at any time are all Securities authenticated by the Trustee, except for those canceled by it, those purchased pursuant to Article 3, those converted pursuant to Article 4, those delivered to the Trustee for cancellation or surrendered for transfer or exchange and those described in this Section 2.09 as not Outstanding.

(b) If a Security is replaced pursuant to Section 2.08, such replaced Security ceases to be Outstanding unless the Company receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

(c) If a Paying Agent holds in respect of the Outstanding Securities on a Fundamental Change Purchase Date or the Final Maturity Date money sufficient to pay the principal of and accrued interest on Securities (or portions thereof) payable on that date, then on and after such

Fundamental Change Purchase Date or Final Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be Outstanding and interest on them shall cease to accrue.

(d) Subject to the restrictions contained in Section 2.10, a Security does not cease to be Outstanding because the Company or an Affiliate of the Company holds the Security.

Section 2.10. Treasury Securities.

In determining whether the Holders of the required principal amount of Securities have concurred in any request, demand, authorization, notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of determining whether the Trustee shall be protected in relying on any such request, demand, authorization, notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded.

Section 2.11. Temporary Securities.

Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company with the consent of the Trustee considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities representing an equal principal amount of Securities. The temporary Securities will be exchanged for definitive Securities in accordance with Sections 2.07 and 2.13 hereof. Until so exchanged, temporary Securities shall have the same rights under this Indenture as the definitive Securities.

Section 2.12. Cancellation.

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange, purchase, payment or conversion. The Trustee and no one else shall cancel, in accordance with its standard procedures, all Securities surrendered for transfer, exchange, purchase, payment, conversion or cancellation and shall dispose of the cancelled Securities in accordance with its customary procedures or deliver the canceled Securities to the Company upon request. All Securities which are purchased or otherwise acquired by the Company or any of its Subsidiaries prior to the Final Maturity Date pursuant to Article 3 shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any Securities that any Holder has converted pursuant to Article 4. The Trustee shall maintain a record of all canceled Securities. The Trustee shall provide the Company a list of all Securities that have been canceled from time to time as requested by the Company in writing.

Section 2.13. Legend; Additional Transfer and Exchange Requirements.

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

such Security has been registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.13.

(b) The provisions below shall apply only to Global Securities:

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

(2) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered, and no transfer of a Global Security in whole or in part shall be registered in the name of any Person other than the Depositary or one or more nominees thereof; provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and in either case a successor Depositary is not appointed by the Company within 90 days after receiving such notice or becoming aware that the Depositary has ceased to be a “clearing agency,” (B) an Event of Default has occurred and is continuing with respect to the Securities or (C) the Company executes and delivers to the Trustee and the Primary Registrar an Officer’s Certificate stating that such Global Security shall be so exchangeable. Any Global Security exchanged pursuant to the preceding sentence shall be so exchanged as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided, however, that any such Security so issued that is registered in the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security.

(3) Securities issued in exchange for a Global Security or any portion thereof that are not issued as a Global Security shall be issued in definitive, fully registered form, without interest coupons, shall have a principal amount equal to that of such Global Security or portion thereof to be so exchanged, shall be registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by the Depositary to the Trustee or the Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof.

(4) Subject to clause (6) of this Section 2.13(b), the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons

that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities.

(5) In the event of the occurrence of any of the events specified in clause (2) of this Section 2.13(b), the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons.

(6) Neither Agent Members nor any other Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, and the Depositary or such nominee, as the case may be, may be treated by the Company, the Trustee and any agent of the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and Holder of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Security.

(7) At such time as all interests in a Global Security have been converted, cancelled or exchanged for Securities in certificated form, such Global Security shall, upon receipt thereof, be cancelled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the Securities Custodian, subject to Section 2.12 of this Indenture. At any time prior to such cancellation, if any interest in a Global Security is converted, canceled or exchanged for Securities in certificated form, the principal amount of such Global Security shall, in accordance with the standing procedures and instructions existing between the Depositary and the Securities Custodian, be appropriately reduced, and an endorsement shall be made on such Global Security, by the Trustee or the Securities Custodian, at the direction of the Trustee, to reflect such reduction.

Section 2.14. CUSIP Numbers.

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

Section 2.15. Calculations.

Except as otherwise specifically stated herein or in the Securities, all calculations to be made in respect of the Securities shall be the obligation of the Company. All calculations made by the Company or its agent as contemplated pursuant to the terms hereof and of the Securities shall be made in good faith and be final and binding on the Holders absent manifest error. The Company shall provide a schedule of calculations to the Trustee, and the Trustee shall be entitled to rely upon the accuracy of the calculations by the Company without independent verification. The Trustee shall forward calculations made by the Company to any Holder of Securities upon request.

Section 2.16. Payment of Interest; Interest Rights Preserved.

Interest on any Security which is payable, and is punctually paid or duly provided for, on the Stated Maturity of such interest shall be paid to the Person in whose name the Security is registered at the close of business on the Regular Record Date for such interest payment.

Any interest on any Security which is payable, but is not punctually paid or duly provided for, on the Stated Maturity of such interest, and interest on such defaulted interest at the then applicable interest rate borne by the Securities, to the extent lawful (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”), shall forthwith cease to be payable to the Holder on the Regular Record Date; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in Subsection (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date (not less than 20 days after such notice) of the proposed payment (the “Special Payment Date”), and on the date of payment the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the Special Payment Date, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this subsection provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the Special Payment Date and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company in writing of such Special Record Date. Unless the Company issues a press release to the same effect, in the name and at the expense of the Company, the Trustee shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder at its address as it appears in the Security Register, not less than 10 days prior to such Special Record Date or notify in such other manner as the Trustee determines, including in accordance with any Applicable Procedures. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Payment Date therefor having been so mailed or otherwise conveyed, such Defaulted Interest shall be paid to the Persons in whose names the Securities are registered on such Special Record Date and shall no longer be payable pursuant to the following paragraph (b).

(b) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any national securities exchange on which the Securities may be listed, and upon such notice as may be required by this Indenture not inconsistent with the requirements of such exchange, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this subsection, such payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section 2.16, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

Section 2.17. Computation of Interest.

Interest on the Securities shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

ARTICLE 3

Section 3.01. Purchase of Securities by the Company for Cash at Option of the Holder Upon a Fundamental Change.

(a) If a Fundamental Change occurs prior to the Final Maturity Date, each Holder of a Security shall have the right, at the option of the Holder, to require the Company to purchase for cash in whole or in part (in principal amounts of $1,000 and integral multiples thereof) the Securities of such Holder at the Fundamental Change Purchase Price on the date specified by the Company that is not less than 30 days and not more than 45 days after the Fundamental Change Effective Date (the “Fundamental Change Purchase Date”).

(13) the CUSIP, ISIN or other similar number of the Securities.

At the Company’s written request, the Trustee shall give such Issuer Fundamental Change Notice in the Company’s name and at the Company’s expense; provided that, in all cases, the text of such Issuer Fundamental Change Notice shall be prepared by the Company. In connection with the delivery of the Issuer Fundamental Change Notice to the Holders, the Company shall publish a notice containing substantially the same information that is required in the Issuer Fundamental Change Notice in a newspaper of general circulation in the City of New York or publish information on a website of the Company or through such other public medium the Company may use at that time. If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the Applicable Procedures relating to the purchase of Global Securities.

(c) A Holder may exercise its rights specified in Section 3.01(a) upon delivery of a written notice (which shall be in substantially the form set forth in the form of Security attached as Exhibit A under the heading “Fundamental Change Purchase Notice” and which may be delivered by letter, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s Applicable Procedures) of the exercise of such rights (a “Fundamental Change Purchase Notice”) to the Paying Agent at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with applicable law.

(1) The Fundamental Change Purchase Notice shall state: (A) if the Securities are in certificated form, the certificate numbers of the Securities which the Holder will deliver to be purchased (or, if the Security is held in global form, any other items required to comply with the Applicable Procedures), (B) the portion of the principal amount of the Securities which the Holder will deliver to be purchased, which portion must be a

principal amount of $1,000 or any integral multiple thereof and (C) that such Security shall be purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions specified in the Securities and in this Indenture.

(2) The delivery of a Security for which a Fundamental Change Purchase Notice has been timely delivered to any Paying Agent and not validly withdrawn prior to, on or after the Fundamental Change Purchase Date (together with all necessary endorsements) at the office of such Paying Agent shall be a condition to the receipt by the Holder of the Fundamental Change Purchase Price therefor.

(3) The Company shall only be obliged to purchase, pursuant to this Section 3.01, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple thereof. Provisions of this Indenture that apply to the purchase of all of a Security also apply to the purchase of such portion of such Security.

(4) Notwithstanding anything herein to the contrary, any Holder delivering to a Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 3.01(c) shall have the right to withdraw such Fundamental Change Purchase Notice in whole or in a portion thereof that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 3.02(b).

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

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

Section 3.02. Effect of Fundamental Change Purchase Notice.

(a) Upon receipt by any Paying Agent of a properly completed Fundamental Change Purchase Notice from a Holder, the Holder of the Security in respect of which such Fundamental Change Purchase Notice was given shall (unless such Fundamental Change Purchase Notice is withdrawn as specified in Section 3.02(b)) thereafter be entitled to receive the Fundamental Change Purchase Price with respect to such Security. Such Fundamental Change Purchase Price shall be paid to such Holder promptly following the later of (1) the Fundamental Change Purchase Date (provided that the conditions in Section 3.01 have been satisfied) and (2) the time of delivery of such Security to a Paying Agent by the Holder thereof in the manner required by Section 3.01(c). Securities in respect of which a Fundamental Change Purchase Notice has been given by the Holder thereof may not be converted in accordance with the provisions of Article 4 on or after the date of the delivery of such Fundamental Change Purchase Notice unless such Fundamental Change Purchase Notice has first been validly withdrawn in accordance with Section 3.02(b) with respect to the Securities to be converted.

(b) A Fundamental Change Purchase Notice may be withdrawn by means of a written notice (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Applicable Procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business Day immediately prior to the Fundamental Change Purchase Date, specifying (1) the principal amount of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which such notice of withdrawal is being submitted, (2) if the Securities are in certificated form, the certificate numbers of the Security being withdrawn in whole or in part and (3) the portion of the principal amount of the Security that will remain subject to the Fundamental Change Purchase Notice, which portion must be a principal amount of $1,000 or an integral multiple thereof.

Section 3.03. Deposit of Fundamental Change Purchase Price.

(a) On or before 10:00 a.m. New York City time on the applicable Fundamental Change Purchase Date, the Company shall deposit with the Trustee or with a Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust as provided in Section 2.04) an amount of money (in immediately available funds if deposited on or after such Fundamental Change Purchase Date), sufficient to pay the aggregate Fundamental Change Purchase Price of all the Securities or portions thereof that are to be purchased as of the Fundamental Change Purchase Date.

(b) If a Paying Agent or the Trustee holds on the Fundamental Change Purchase Date in accordance with the terms hereof an amount of money sufficient to pay the Fundamental Change Purchase Price of any Security (or portion thereof) for which a Fundamental Change Purchase Notice has been tendered and not withdrawn in accordance with this Indenture then, immediately following the applicable Fundamental Change Purchase Date, whether or not the Security is delivered to the Paying Agent, such Security shall cease to be outstanding, interest, shall cease to accrue, and the rights of the Holder in respect of the Security shall terminate (other than the right to receive the Fundamental Change Purchase Price upon delivery of the Security as aforesaid).

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

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

Section 3.04. Repayment to the Company.

To the extent that the aggregate amount of cash deposited by the Company pursuant to Section 3.03 exceeds the aggregate Fundamental Change Purchase Price of the Securities or portions thereof that the Company is obligated to purchase, then promptly after the Fundamental Change Purchase Date the

Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company, or if such money is then held by the Company in trust, it shall be discharged from the trust.

Section 3.05. Securities Purchased In Part.

Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Fundamental Change Purchase Date, as the case may be, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder (which must be equal to $1,000 principal amount or any integral multiple thereof), in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Security so surrendered that is not purchased.

Section 3.06. Compliance With Securities Laws Upon Purchase of Securities.

In connection with any offer to purchase Securities under Section 3.01, the Company shall (a) comply with the provisions of the tender offer rules under the Exchange Act which may then be applicable, (b) file the related Schedule TO (or any successor or similar schedule, form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and obligations of the Company under Sections 3.01 through 3.04 to be exercised in the time and in the manner specified therein. To the extent that compliance with any such laws, rules and regulations would result in a conflict with any of the terms hereof, this Indenture is hereby modified to the extent required for the Company to comply with such laws, rules and regulations.

Section 3.07. Purchase of Securities In Open Market.

The Company may purchase Securities in the open market or by tender at any price or pursuant to private agreements.

ARTICLE 4

CONVERSION

Section 4.01. Conversion Privilege and Conversion Rate.

(a) Any Security or portion thereof that is an integral multiple of $1,000 principal amount may be converted by the Holder thereof in accordance with the provisions of this Article 4. Upon conversion, Holders shall be entitled to receive the amount of cash and, if applicable, shares of Common Stock determined in the manner provided in Section 4.12. Securities may be converted prior to the close of business on the third Business Day immediately preceding the Final Maturity Date at the Conversion Rate in effect at the time of such conversion only under the following circumstances:

(1) on any Business Day in any calendar quarter commencing at any time after June 30, 2007, and only during such calendar quarter, if, as of the last day of the immediately preceding calendar quarter, the Closing Price of the Common Stock for at

least 20 Trading Days in the period of 30 consecutive Trading Days ending on the last Trading Day of such preceding calendar quarter was more than 130% of the applicable Conversion Price on the last day of such preceding calendar quarter;

(2) on any Business Day during the five Business Day period after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of Securities, as determined by the Trustee following a request by a Holder in accordance with the procedures described in Section 4.01(e)(ii), for each Trading Day of that period was less than 98% of the product of the Closing Price of the Common Stock on such day and the then applicable Conversion Rate per $1,000 principal amount of Securities.

(3) if the Company distributes to all holders of Common Stock any rights entitling them to purchase, for a period expiring within 45 days of distribution, Common Stock, or securities convertible into Common Stock, at less than, or having a conversion price per share less than, the Closing Price of the Common Stock on the Trading Day immediately preceding the declaration date for such distribution;

(4) if the Company distributes to all holders of Common Stock assets, cash, debt securities or rights to purchase the Company’s securities, which distribution has a per share value as determined by the Board of Directors exceeding 15% of the Closing Price per share of the Common Stock on the Trading Day immediately preceding the declaration date for such distribution;

(5) if the Company is a party to any transaction or event (including, but not limited to, any consolidation, merger or binding share exchange, other than changes resulting from a subdivision or combination) that is not otherwise a Fundamental Change pursuant to which all or substantially all shares of the Common Stock would be converted into cash, securities or other property (provided that the Securities shall not become convertible by reason of a merger, consolidation or other transaction effected by the Company with one of its direct or indirect Subsidiaries for the purpose of changing the Company’s state of incorporation or organization to any other state within the United States or the District of Columbia);

(6) if a Fundamental Change occurs; or

(7) at any time during the period beginning on ___, ___and ending at the close of business on the third Business Day immediately preceding the Final Maturity Date.

(b) The Trustee shall have no obligation to determine the Trading Price of the Securities and whether the Securities are convertible pursuant to clause (2) of Section 4.01(a) unless the Company has requested such determination and the Company shall have no obligation to make such request unless a Holder of the Securities provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Securities would be less than 98% of the product of the Closing Price of the Common Stock and the then applicable Conversion Rate per $1,000 principal amount of Securities. At such time, the Company shall instruct the Trustee to determine the Trading Price of the Securities beginning on the next

Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Securities is greater than 98% of the product of the Closing Price of the Common Stock and the then applicable Conversion Rate per $1,000 principal amount of the Securities.

(c) In the case of a distribution contemplated by clause (3) or (4) of Section 4.01(a), the Company shall notify Holders and the Trustee at least 35 days prior to the ex-dividend date (defined below) for such distribution (the “Distribution Notice”). Once the Company has given the Distribution Notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the Business Day prior to the ex-dividend date or the Company’s announcement that such distribution will not take place. In the event of a distribution contemplated by clause (3) or (4) of Section 4.01(a), Holders may not convert the Securities if the Holders will otherwise participate in such distribution on an as converted basis (assuming for this purpose that the Securities were convertible solely into a number of shares of Common Stock equal to the then applicable Conversion Rate). The “ex-dividend date” is the first date upon which a sale of the Common Stock does not automatically transfer the right to receive the relevant distribution from the seller of the Common Stock to its buyer. The Company will provide written notice to the Conversion Agent as soon as reasonably practicable of any anticipated or actual event or transaction that will cause or causes the Securities to become convertible pursuant to clauses (3) or (4) of Section 4.01(a).

(d) In the case of a transaction contemplated by clause (5) of Section 4.01(a), the Company will notify Holders and the Trustee as promptly as practicable following the date the Company publicly announces such transaction (but in no event less than 15 days prior to the anticipated effective date of such transaction). Holders may surrender Securities for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of such transaction until the earlier of the date which is 15 days after the actual effective date of such transaction or the date of the Company’s announcement that such transaction will not take place.

(e) In the case of a Fundamental Change, the Company shall provide notice thereof (a “Fundamental Change Conversion Notice”) to the Holders of Securities and the Trustee at least 15 days prior to date that is anticipated to be the Fundamental Change Effective Date. Holders may surrender Securities for conversion at any time beginning 15 days before the date that is anticipated to be the Fundamental Change Effective Date until the Trading Day prior to the Fundamental Change Purchase Date.

(f) The conversion rights pursuant to this Article 4 shall commence on the Issue Date of the Securities and expire at the close of business on the third Business Day immediately preceding the Final Maturity Date, but shall be exercisable only during the time periods specified with respect to each circumstance pursuant to which the Securities become convertible, subject, in the case of conversion of any Global Security, to any Applicable Procedures.

(g) Securities in respect of which a Fundamental Change Purchase Notice has been delivered may not be surrendered for conversion pursuant to this Article 4 prior to a valid withdrawal of such Fundamental Change Notice, in accordance with the provisions of Article 3.

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

(i) The Conversion Rate shall be adjusted in certain instances as provided in Section 4.01(j) and Section 4.06.

(j) If a Fundamental Change occurs prior to the Final Maturity Date as a result of a transaction described in clauses (1), (2) or (4) of the definition of the term “Change of Control” and a Holder elects to convert its Securities “in connection with” such transaction, the Company shall pay a “Make Whole Premium” by increasing the applicable Conversion Rate for the Securities surrendered for conversion by a number of additional shares of Common Stock as provided in this Section 4.01(i) (the “Additional Shares”). A conversion of Securities shall be deemed for these purposes to be “in connection with” such a transaction if the notice of conversion is received by the Conversion Agent from and including the Fundamental Change Effective Date and prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date.

The number of Additional Shares per $1,000 principal amount of Securities constituting the Make Whole Premium shall be determined by reference to the table below and shall be based on the date on which the Fundamental Change Effective Date occurs and the price (the “Stock Price”) paid, or deemed to be paid, per share of Common Stock in such transaction. If holders of Common Stock receive only cash in the Fundamental Change transaction, the Stock Price shall be the cash amount paid per share of Common Stock. Otherwise, the Stock Price shall be the average of the Closing Prices of the Common Stock for each of the ten consecutive Trading Days prior to but excluding the Fundamental Change Effective Date.

The following table sets forth the Additional Share amounts, if any, by which the applicable Conversion Rate shall be increased for each Stock Price and Fundamental Change Effective Date.

If the actual Stock Price or Fundamental Change Effective Date is not set forth in the table above, then:

(i) if the actual Stock Price on the Fundamental Change Effective Date is between two Stock Price amounts in the table or the actual Fundamental Change Effective Date is between two Fundamental Change Effective Dates in the table, the Additional Share amounts will be determined by a straight-line interpolation between the Additional Share amounts set forth for the

higher and lower Stock Prices and the two Fundamental Change Effective Dates on the table based on a 365-day year;

(ii) if the actual Stock Price on the Fundamental Change Effective Date exceeds $___ per share of Common Stock, subject to adjustment as set forth herein, no adjustment to the Conversion Rate shall be made; and

(iii) if the actual Stock Price on the Fundamental Change Effective Date is less than $ per share of Common Stock, subject to adjustment as set forth herein, no adjustment to the Conversion Rate shall be made.

The Stock Prices set forth in the first column of the table above will be adjusted as of any date on which the Conversion Rate of the Securities is adjusted pursuant to Section 4.06 hereof. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Share amounts set forth in the table above will be adjusted in the same manner as the Conversion Rate as set forth in Section 4.06 hereof.

Notwithstanding the foregoing, in no event shall the Conversion Rate exceed ___shares per $1,000 principal amount of Securities, subject to adjustment in the same manner as the Conversion Rate as set forth in subsections (a) through (e) of Section 4.06 hereof.

Section 4.02. Conversion Procedure.

(a) To convert a Security, a Holder must (1) complete and manually sign the conversion notice on the back of the Security (which shall be substantially in the form set forth in the form of Security attached as Exhibit A under the heading “Conversion Notice”) and deliver such notice to the Conversion Agent, (2) surrender the Security to the Conversion Agent, (3) furnish appropriate endorsements and transfer documents if required by the Conversion Agent, (4) pay an amount equal to the interest payable on the next Interest Payment Date if and as required by Section 4.02(c) and (5) pay all transfer or similar taxes, if required pursuant to Section 4.04. The date on which the Holder of a Security satisfies all of the foregoing requirements is the “Conversion Date” with respect to such Security. Upon the conversion of a Security, the Company shall deliver the amounts determined in accordance with Section 4.12 which shall be owing upon such conversion as promptly as practicable after the applicable Conversion Reference Period but in any event not later than the third Business Day following the last Trading Day of such Conversion Reference Period. Anything herein to the contrary notwithstanding, in the case of Global Securities, Securities may be surrendered in accordance with the Applicable Procedures of the Depositary as in effect from time to time.

(b) A Holder shall not be entitled to any rights of a holder of Common Stock until such Holder has converted its Securities and received upon conversion thereof shares of Common Stock. The person in whose name any certificate or certificates for shares of Common Stock shall be issuable upon such conversion, if any, shall become on the date any such certificate or certificates are delivered to such Holder in accordance with the provisions of this Article 4, the holder of record of the shares represented thereby. Except as set forth in this Indenture, no payment or adjustment will be made for dividends or distributions declared or

made on shares of Common Stock issued upon conversion of a Security prior to the issuance of such shares of Common Stock.

(c) Holders of Securities surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date will receive the semiannual interest payable on such Securities on the corresponding Interest Payment Date notwithstanding the conversion, and such interest shall be payable on the corresponding Interest Payment Date to the Holder of the Security as of the close of business on the Regular Record Date. Upon surrender of any such Securities for conversion after the close of business on such Regular Record Date, such Securities shall also be accompanied by payment by the Holders of such Securities in funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date; provided that no such payment need be made: (1) in connection with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security. Except as otherwise provided in this Section 4.02(c), no payment or adjustment will be made for accrued and unpaid interest on a converted Security. Accrued and unpaid interest shall be deemed paid in full, rather than cancelled, extinguished or forfeited. The Company shall not be required to convert any Securities which are surrendered for conversion without payment of interest as required by this Section 4.02(c).

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

Section 4.03. Fractional Shares.

The Company will not issue fractional shares of Common Stock upon conversion of Securities. If more than one Security shall be surrendered for conversion at one time by the same Holder, the number of full shares that shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Securities (or specified portions thereof to the extent permitted hereby) so surrendered. In lieu of any fractional shares, the Company shall pay an amount in cash equal to the applicable fraction of a share multiplied by the arithmetic average of the Volume Weighted Average Price of the Common Stock for the 40 consecutive Trading Days of the Conversion Reference Period, rounding to the nearest whole cent.

Section 4.04. Taxes on Conversion.

The issue of stock certificates, if any, on conversion of Securities shall be made without charge to the converting Holder for any documentary, stamp or similar issue or transfer tax in respect of the issue thereof. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the Holder of any Security converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the

Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

Section 4.05. Company To Provide Common Stock.

(a) The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities in accordance with the provisions of this Indenture.

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

(c) The Company will endeavor promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will list or cause to have listed such shares of Common Stock on the New York Stock Exchange, or each national securities exchange or over the counter market or such other market on which the Common Stock is then listed or quoted.

Section 4.06. Adjustment of Conversion Rate.

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

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


CR1 =		CR0 x OS1/OS0

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate in effect taking such event into account

OS0 =		the number of shares of Common Stock outstanding immediately prior to such event

OS1 =		the number of shares of Common Stock outstanding immediately after such event.

Any adjustment made pursuant to this Section 4.06(a) shall become effective on the date that is immediately after (x) the date fixed for the determination of stockholders entitled to receive such dividend or other distribution or (y) the date on which such split or combination becomes effective, as applicable. If any dividend or distribution described in this clause Section 4.06(a) is declared but not so paid or made,

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

(b) If the Company issues to all holders of Common Stock any rights, warrants, options or other securities entitling them for a period of not more than 45 days after the date of issuance thereof to subscribe for or purchase Common Stock, or if the Company issues to all holders of Common Stock securities convertible into Common Stock for a period of not more than 45 days after the date of issuance thereof, in either case at an exercise price per share of Common Stock or a conversion price per share of Common Stock less than the Closing Price of the Common Stock on the Business Day immediately preceding the time of announcement of such issuance, the Conversion Rate will be adjusted based on the following formula:


CR1 =		CR0 x (OS0+X)/(OS0+Y)

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate taking such event into account

OS0 =		the number of shares of Common Stock outstanding immediately prior to such event

X =		the total number of shares of Common Stock issuable pursuant to such rights, warrants, options, other securities or convertible securities

Y =		the number of shares of Common Stock equal to the quotient of (A) the aggregate price payable to exercise such rights, warrants, options, other securities or convertible securities and (B) the average of the Closing Prices of the Common Stock for the 10 consecutive Trading Days prior to the Business Day immediately preceding the date of announcement for the issuance of such rights, warrants, options, other securities or convertible securities.

For purposes of this Section 4.06(b), in determining whether any rights, warrants, options, other securities or convertible securities entitle the holders to subscribe for or purchase, or exercise a conversion right for, Common Stock at less than the applicable Closing Price of the Common Stock, and in determining the aggregate exercise or conversion price payable for such Common Stock, there shall be taken into account any consideration received by the Company for such rights, warrants, options, other securities or convertible securities and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors of the Company. Any adjustment made pursuant to this Section 4.06(b) shall become effective on the date that is immediately after the date fixed for the determination of shareholders entitled to receive such rights, warrants, options, other securities or convertible securities. If any right, warrant, option, other security or convertible security described in this Section 4.06(b) is not exercised or converted prior to the expiration of the exercisability or convertibility thereof, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such right, warrant, option, other security or convertible security had not been so issued.

(c) If the Company distributes capital stock, evidences of indebtedness or other assets or property of the Company to all holders of Common Stock, excluding:

(1) dividends, distributions, rights, warrants, options, other securities or convertible securities referred to in Section 4.06(a) or (b) above,

(2) dividends or distributions paid exclusively in cash, and

(3) Spin-Offs described below in this Section 4.06(c),

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


CR1 =		CR0 x SP0/(SP0-FMV)

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate taking such event into account

SP0 =		the Closing Price of the Common Stock on the Trading Day immediately preceding the ex-dividend date for such distribution

FMV =		the fair market value (as determined in good faith by the Board of Directors of the Company) of the capital stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock on the earlier of the record date or the ex-dividend date for such distribution.

An adjustment to the Conversion Rate made pursuant to this paragraph shall be made successively whenever any such distribution is made and shall become effective on the ex-dividend date for such distribution.

If the Company distributes to all holders of Common Stock capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit of the Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on the date fixed for determination of holders of Common Stock entitled to receive such distribution will be adjusted based on the following formula:


CR1 =		CR0 x (FMV0+MP0)/MP0

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate taking such event into account


FMV0 =		the average of the Closing Prices of the capital stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Days after the effective date of the Spin-Off

MP0 =		the average of the Closing Prices of the Common Stock over the first 10 consecutive Trading Days after the effective date of the Spin-Off.

An adjustment to the Conversion Rate made pursuant to this paragraph will occur on the 10th Trading Day from and including the effective date of the Spin-Off.

If any such dividend or distribution described in this Section 4.06(c) is declared but not paid or made, the new Conversion Rate shall be readjusted to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(d) If the Company pays or makes any dividend or distribution consisting exclusively of cash to all holders of Common Stock, the Conversion Rate will be adjusted based on the following formula:


CR1 =		CR0 x (SP0-T)/(SP0-C)

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate taking such event into account

SP0 =		the average of the Closing Prices of the Common Stock over the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the ex-dividend date for such distribution

T =		the Dividend Threshold Amount, which shall initially be $0.06 per quarter, adjusted to take into account events that cause adjustments to the Conversion Rate and as further adjusted to account for any change in the frequency of payment of regular dividends by the Company; provided that the Dividend Threshold Amount shall be deemed to be zero if the dividend is not a regularly scheduled dividend

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

An adjustment to the Conversion Rate made pursuant to this Section 4.06(d) shall become effective on the ex-dividend date for such dividend or distribution. If any dividend or distribution described in this Section 4.06(d) is declared but not so paid or made, the new Conversion Rate shall be readjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

If the Company fails to pay a cash dividend or distribution for a period in which a regularly scheduled dividend has in prior periods been paid in accordance with past practice, the Conversion Rate shall be adjusted using the formula in this Section 4(d), with the ex-dividend date being deemed to be the second to last trading day in the second month of the calendar quarter in question, and “C” being deemed to be zero.

Whenever the Conversion Rate is adjusted, the Dividend Threshold Amount shall be adjusted by multiplying such Dividend Threshold Amount by a fraction, the numerator of which is the Conversion Rate prior to adjustment and the denominator of which is the Conversion Rate following such adjustment, except that no such adjustment will be made to the Dividend Threshold Amount on account of any adjustment to the Conversion Rate pursuant to this Section 4(d).

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


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

where

CR0 =		the Conversion Rate in effect immediately prior to the adjustment relating to such event

CR1 =		the new Conversion Rate taking such event into account

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

OS0 =		the number of shares of Common Stock outstanding immediately prior to the date such tender or exchange offer expires

OS1 =		the number of shares of Common Stock outstanding immediately after such tender or exchange offer expires (after giving effect to the purchase or exchange of shares pursuant to such tender or exchange offer)

SP1 =		the average of the Closing Prices of Common Stock for the 10 consecutive Trading Days commencing on the Trading Day next succeeding the date such tender or exchange offer expires.

If the application of the foregoing formula would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made.

Any adjustment to the Conversion Rate made pursuant to this Section 4.06(e) shall become effective on the date immediately following the determination of the average of the Closing Prices of Common Stock for purposes of SP1 above. If the Company or one of its subsidiaries is obligated to

purchase Common Stock pursuant to any such tender or exchange offer but is permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

(f) Notwithstanding the provisions of this Section 4.06, the Conversion Rate shall not exceed ___shares per $1,000 principal amount of Securities, subject to adjustment in the manner that the Conversion Rate is subject to adjustment as set forth in subsections (a) through (e) of this Section 4.06.

(g) In addition to the adjustments pursuant to clauses (a) through (e) above, the Company may increase the Conversion Rate in order to avoid or diminish any income tax to holders of Common Stock resulting from any dividend or distribution of capital shares (or rights to acquire Common Stock) or from any event treated as such for income tax purposes. The Company may also, from time to time, to the extent permitted by applicable law, increase the Conversion Rate by any amount for any period if the Company has determined that such increase would be in the best interests of the Company. If the Company makes such determination, it will be conclusive and the Company will mail to Holders of the Securities a notice of the increased Conversion Rate and the period during which it will be in effect at least fifteen (15) days prior to the date the increased Conversion Rate takes effect in accordance with applicable law.

(h) If the Company has in effect a rights plan while any Securities remain outstanding, Holders will receive, upon a conversion of Securities in respect of which the Company is required to deliver shares of Common Stock, in addition to such shares of Common Stock, rights under the Company’s stockholder rights agreement unless, prior to conversion, the rights have expired, terminated or been redeemed or unless the rights have separated from the Common Stock. If the rights provided for in the rights plan adopted by the Company have separated from the Common Stock in accordance with the provisions of the applicable stockholder rights agreement so that Holders would not be entitled to receive any rights in respect of Common Stock, if any, that the Company is required to deliver upon conversion of Securities, the Conversion Rate will be adjusted at the time of separation as if the Company had distributed to all holders of Common Stock capital stock, evidences of indebtedness or other assets or property pursuant to Section 4.06(c) above, subject to readjustment upon the subsequent expiration, termination or redemption of the rights.

(i) For purposes of this Section 4.06, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock.

Section 4.07. No Adjustment.

(a) The Company shall not be required to make any adjustment to the Conversion Rate in accordance with the provisions of Section 4.06 if Holders of the Securities are permitted to participate, on an as-converted basis, in the transactions described in Section 4.06 (assuming for this purpose that each $1,000 principal amount of Securities were convertible solely into a number of shares of Common Stock equal to the Conversion Rate).

(b) No adjustment in the Conversion Rate shall be required to be made unless the adjustment would require an increase or decrease of at least 1% of the Conversion Price. If the adjustment is not made because the adjustment does not change the Conversion Price by at least 1%, then the adjustment that is not made will be carried forward and taken into account in any future adjustment. All required calculations will be made to the nearest cent or 1/1,000th of a share, as the case may be. Notwithstanding the foregoing, all adjustments not previously made shall have effect with respect to any conversion of Securities.

(c) Notwithstanding anything to the contrary contained herein, in addition to the other events set forth herein on account of which no adjustment to the Conversion Rate shall be made, the applicable Conversion Rate shall not be adjusted for: (i) the issuance of any Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in Common Stock under any plan; (ii) the issuance of any shares of Common Stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan, employee agreement or arrangement or program of the Company; (iii) the issuance of any shares of Common Stock pursuant to any option, warrant, right, or exercisable, exchangeable or convertible security outstanding as of the date the Securities were first issued; (iv) a change in the par value of the Common Stock; (v) accumulated and unpaid dividends or distributions; and (vi) as a result of a tender offer solely to holders of fewer than 100 shares of Common Stock.

(d) Notwithstanding anything in this Section 4.06 to the contrary, in no event shall the Conversion Rate be adjusted so that the Conversion Price would be less than $0.01.

Section 4.08. Notice of Adjustment.

Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee, an Officer’s Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Trust Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that the last Conversion Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to Holders within 20 Business Days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

Section 4.09. Notice of Certain Transactions.

In the event that the Company takes any action which would require an adjustment to the Conversion Rate, the Company takes any action that requires the execution of a supplemental indenture in accordance with the provisions of Section 4.10 or if there is a dissolution or liquidation of the Company, the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail such notice at least 20 days before such proposed effective date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in this Section 4.09.

Section 4.10. Effect of Reclassification, Consolidation, Merger or Sale on Conversion Privilege.

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

(1) any recapitalization, reclassification or change of the Common Stock, other than (A) a change in par value, or from par value to no par value, or from no par value to par value, or (B) as a result of subdivision or a combination,

(2) a consolidation, merger or combination of the Company with another Person,

(3) a sale, lease or other transfer to another Person of all or substantially all of the consolidated assets of the Company and its Subsidiaries, or

(4) any statutory share exchange of the Company with another person,

in each case as a result of which holders of Common Stock are entitled to receive stock, other securities, other property or assets (including cash or any combination thereof) with respect to or in exchange for Common Stock, the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that from and after the effective date of such Business Combination, upon conversion of Securities, the settlement of the Conversion Value in accordance with the provisions of Section 4.12 shall be based on, and each Remaining Share, if any, deliverable in respect of any such settlement shall consist of, the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) which holders of Common Stock are entitled to receive in respect of each share of Common Stock upon such Business Combination. For purposes of the foregoing, where a Business Combination involves a transaction that causes the Common Stock to be converted into the right to receive more than a single type of consideration based upon any form of stockholder election, such consideration will be deemed to be the weighted average of the types and amounts of consideration received by the holders of Common Stock that affirmatively make such an election. If, in the case of any such Business Combination, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such Business Combination, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including to the extent practicable the provisions providing for the repurchase rights set forth in Article 3 hereof. The Company shall not become a party to any Business Combination unless its terms are materially consistent with the provisions of this Section 4.10. The above provisions of this Section 4.10 shall similarly apply to successive Business Combinations. None of the provisions of this Section 4.10 shall affect the right of a Holder of Securities to convert its Securities in accordance with the provisions of this Article 4 prior to the effective date of a Business Combination.

If this Section 4.10(a) applies to any event or occurrence, Section 4.06 hereof shall not apply.

(b) In the event the Company shall execute a supplemental indenture pursuant to this Section 4.10, the Company shall promptly file with the Trustee (1) an Officer’s Certificate briefly stating the reasons therefore and that all conditions precedent have been complied with

and (2) an Opinion of Counsel to the effect that all conditions precedent thereto and hereunder have been complied with, and shall promptly mail notice of the execution of such supplemental indenture to all Holders. Failure to mail such notice or any defect therein shall not affect the validity of such transaction and such supplemental indenture.

Section 4.11. Trustee’s Disclaimer.

(a) The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officer’s Certificate and Opinion of Counsel, including the Officer’s Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.08. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities, and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 4, including, without limitation, whether or not a Supplemental Indenture is required to be executed.

(b) The Trustee shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.10, but may accept as conclusive evidence of the correctness thereof, and shall be fully protected in relying upon, the Officer’s Certificate and Opinion of Counsel, with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.10.

Section 4.12. Settlement Upon Conversion.

(a) Holders surrendering Securities for conversion shall be entitled to receive, for each $1,000 principal amount of Securities surrendered for conversion: (A) cash in an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value; and (B) if the Conversion Value is greater than $1,000, a number of shares of Common Stock (the “Remaining Shares”) equal to the sum of the Daily Share Amounts for each of the 40 consecutive Trading Days in the Conversion Reference Period, appropriately adjusted to reflect events occurring during the Conversion Reference Period that would result in an adjustment to Conversion Rate in accordance with the provisions of Section 4.06, subject to the Company’s right to deliver cash in lieu of all or a portion of such Remaining Shares as set forth in Section 4.12(b). The Company will deliver such cash and any shares of Common Stock, together with any cash payable for fractional shares, to such Holder in accordance with Section 4.02(a).

(b) The Company may elect to pay cash to the Holders of Securities surrendered for conversion in lieu of all or a portion of the Remaining Shares otherwise issuable pursuant to Section 4.12(a). In such event, on any day prior to the first Trading Day of the applicable Conversion Reference Period, the Company may specify a percentage of the Daily Share Amount that will be settled in cash (the “Cash Percentage”). If the Company elects to specify a Cash Percentage, the amount of cash that the Company will deliver for each Trading Day in the applicable Conversion Reference Period will equal the product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading Day and (3) the Volume Weighted Average Price of the Company’s Common Stock on such Trading Day. The number of shares that the Company shall deliver in respect of each Trading Day in the applicable Conversion Reference Period will

be a percentage of the Daily Share Amount equal to 100% minus the Cash Percentage. If the Company does not specify a Cash Percentage by the start of the applicable Conversion Reference Period, the Company shall settle 100% of the Daily Share Amount for each Trading Day in the applicable Conversion Reference Period with shares of Common Stock; provided, however, that the Company shall pay cash in lieu of fractional shares otherwise issuable upon conversion of the Securities in accordance with Section 4.03.

(c) For the purposes of Sections 4.12(a) and (b), in the event that any of Conversion Value, Daily Conversion Value, Daily Share Amounts, or Volume Weighted Average Price is not calculable for all portions of the Conversion Reference Period, the Company’s Board of Directors shall in good faith determine the values necessary to calculate the Conversion Value, Daily Conversion Value, Daily Share Amounts, and Volume Weighted Average Price (which calculations shall be evidenced by an Officer’s Certificate delivered to the Trustee).

ARTICLE 5

COVENANTS

Section 5.01. Payment of Securities.

(a) The Company shall promptly make all payments in respect of the Securities on the dates and in the manner provided in the Securities and this Indenture. A payment of principal or interest shall be considered paid on the date it is due if the Paying Agent (other than the Company) (or if the Company is the Paying Agent, the segregated account or separate trust fund maintained by the Company pursuant to Section 2.04) holds by 10:00 a.m., New York City time, on that date money, deposited by or on behalf of the Company sufficient to make the payment. Accrued and unpaid interest on any Security that is payable (whether or not punctually paid or duly provided for) on any Interest Payment Date shall be paid to the Person in whose name that Security is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. The Company shall, to the fullest extent permitted by law, pay interest in immediately available funds on overdue principal and interest at the annual rate borne by the Securities compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the day preceding the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable on demand.

(b) Payment of the principal of and interest, if any, on the Securities shall be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York (which shall initially be the Corporate Trust Office of the Trustee) in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest on any Certificated Securities having an aggregate principal amount of $5,000,000 or less may be made by check mailed to the address of the Person entitled thereto as such address appears in the Register; provided further that a Holder of a Certificated Security having an aggregate principal amount of more than $5,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Trustee at least 10 Business Days prior to the payment date. Any wire

transfer instructions received by the Trustee will remain in effect until revoked by the Holder. In the case of a permanent Global Security, interest payable on any applicable payment date will be paid to the Depositary, with respect to that portion of such permanent Global Security held for its account by Cede & Co. for the purpose of permitting such party to credit the interest received by it in respect of such permanent Global Security to the accounts of the beneficial owners thereof.

Section 5.02. Reports by Company and the Guarantors.

(a) The Company shall deliver to the Trustee, within 15 days after it files them with the SEC, copies of all annual reports, quarterly reports and other documents that it files with the SEC pursuant to Sections 13 or 15(d) of the Exchange Act. The Company also shall comply with the provisions of TIA Section 314(a).

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

Section 5.03. Compliance Certificates.

The Company shall deliver to the Trustee, within one hundred twenty (120) days after the end of each fiscal year of the Company (beginning with the fiscal year ending December 31, 2007), an Officer’s Certificate as to the signer’s knowledge of the Company’s compliance with all conditions and covenants on its part contained in this Indenture and stating whether or not the signer knows of any Default or Event of Default. If such signer knows of such a Default or Event of Default, the Officer’s Certificate shall describe the Default or Event of Default and the efforts to remedy the same. For the purposes of this Section 5.03, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. Such certificates need not comply with Section 12.04 of this Indenture.

Section 5.04. Further Instruments and Acts.

Upon request of the Trustee, the Company and the Guarantors will execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purposes of this Indenture.

Section 5.05. Maintenance of Corporate Existence.

Subject to Article 6, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence.

Section 5.06. Stay, Extension And Usury Laws.

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

waives all benefit or advantage of any such law and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 5.07. Maintenance of Office or Agency.

The Company shall maintain an office or agency where Securities may be presented or surrendered for payment. The Company also will maintain an office or agency where Securities may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The office of the Trustee, at its Corporate Trust Office, will be such office or agency of the Company, unless the Company shall designate and maintain some other office or agency for one or more of such purposes. The Company will give prompt written notice to the Trustee of the location and any change in the location of any such offices or agencies. If at any time the Company shall fail to maintain any such required offices or agencies or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the office of the Trustee and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Company may from time to time designate one or more other offices or agencies (in or outside of The City of New York) where the Securities may be presented or surrendered for any or all such purposes, and may from time to time rescind such designation. The Company will give prompt written notice to the Trustee of any such designation or rescission and any change in the location of any such office or agency.

Section 5.08. Guarantees.

If any Subsidiary of the Company (including any Subsidiary of the Company formed or acquired after the Issue Date) shall become a guarantor under the 5.750% Notes or the 6.375% Notes, then such Subsidiary shall (i) execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary shall unconditionally Guarantee all of the Company’s obligations under the Securities and this Indenture on the terms set forth in Article Eleven and (ii) deliver to the Trustee an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Subsidiary, subject to customary exceptions. Such opinion need not comply with Section 12.04 of this Indenture.

ARTICLE 6

CONSOLIDATION; MERGER; SALE OF ASSETS

Section 6.01. Company May Consolidate, Etc., Only on Certain Terms.

(a) The Company shall not consolidate with or merge with or into (whether or not the Company is the surviving Person) any other entity and the Company shall not sell, convey, assign, transfer, lease or otherwise dispose of all or substantially all of the Company’s assets to any Person in a single transaction or series of related transactions, unless:

(1) either (A) the Company shall be the surviving Person or (B) the surviving Person (if other than the Company) shall be a corporation or limited liability company organized and validly existing under the laws of the United States of America or any

State thereof or the District of Columbia, and shall, in any such case, expressly assume by a supplemental indenture, the due and punctual payment of the principal of and interest on all the Securities and the performance and observance of every covenant of this Indenture to be performed or observed on the part of the Company;

(2) after giving effect to the transaction, no Default or Event of Default shall have occurred and be continuing;

(3) if the Company will not be the resulting or surviving Person, the Company shall have, at or prior to the effective date of such consolidation or merger or sale, conveyance, assignment, transfer, lease or other disposition, delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, merger or transfer complies with this Article 6.01 and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with this Article, and that all conditions precedent herein provided for relating to such transaction have been complied with.

Upon any consolidation of the Company with, or merger of the Company into, any other Person or any sale, conveyance, assignment, transfer, lease or other disposition of all or substantially all of the Company’s assets in accordance with Section 6.01, the successor Person formed by such consolidation or into which the Company is merged or to which such sale, conveyance, assignment, transfer, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities.

ARTICLE 7

DEFAULT AND REMEDIES

Section 7.01. Events of Default.

(a) An “Event of Default” wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) a default by the Company in the payment of the principal amount or Fundamental Change Purchase Price of any Security when the same becomes due and payable whether at the Final Maturity Date, upon purchase, acceleration or otherwise; or

(2) a default by the Company in the payment of any interest under the Securities, which default continues for 30 days after the date when due; or

(3) a default by the Company in the delivery when due of all cash and any shares of Common Stock deliverable upon conversion of the Securities, which default continues for 15 days; or

(4) failure by the Company to provide an Issuer Fundamental Change Notice within the time required to provide such notice as set forth in Section 3.01(b) hereof; or

(5) the failure by the Company to perform or observe any other term, covenant or agreement contained in the Securities or this Indenture for a period of 60 days after receipt by the Company of a Notice of Default specifying such failure; or

(6) one or more defaults shall have occurred under any of the agreements, indentures or instruments under which the Company or any Restricted Subsidiary then has outstanding indebtedness in excess of $40 million, individually or in the aggregate, and either:

(A) such default results from the failure to pay such indebtedness at its stated final maturity and such default has not been cured or the indebtedness repaid in full within ten days of the default; or

(B) such default or defaults have resulted in the acceleration of the maturity of such indebtedness and such acceleration has not been rescinded or such indebtedness repaid in full within ten days of the acceleration;

(7) one or more judgments or orders that exceed $40 million in the aggregate (net of amounts covered by insurance or bonded) for the payment of money have been entered by a court or courts of competent jurisdiction against the Company or any Restricted Subsidiary and such judgment or judgments have not been satisfied, stayed, annulled or rescinded within 60 days after such judgment or judgments become final and nonappealable; or

(8) any Guarantee by a Significant Subsidiary shall for any reason cease to be, or shall for any reason be asserted in writing by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms, except to the extent contemplated by this Indenture and any such Guarantee; or

(9) the Company or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary insolvency proceeding;

(B) consents to the entry of an order for relief against it in an involuntary insolvency proceeding or consents to its dissolution or winding-up;

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

or takes any comparable action under any foreign laws relating to insolvency; provided, however, that the liquidation of any Restricted Subsidiary into another Restricted Subsidiary, other than as part of a credit reorganization, shall not constitute an Event of Default under this Section 7.01(a)(9); or

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

(A) is for relief against the Company or any Significant Subsidiary in an involuntary insolvency proceeding;

(B) appoints a Custodian of the Company or any Significant Subsidiary or for any substantial part of their property;

(D) orders the presentation of any plan or arrangement, compromise or reorganization of the Company or any significant subsidiary; or

(E) grants any similar relief under any foreign laws;

and in each such case the order or decree remains unstayed and in effect for 90 days.

(b) Notwithstanding Section 7.01(a) no Event of Default under clause (5) of Section 7.01(a) shall occur until the Trustee notifies the Company in writing, or the Holders of at least 25% in aggregate principal amount of the Securities then Outstanding notify the Company and the Trustee in writing, of the Default (a “Notice of Default”), and the Company does not cure the Default within the time specified in clause (5) of Section 7.01(a), or obtain a waiver, after receipt of such notice. A notice given pursuant to this Section 7.01 shall be given by registered or certified mail, must specify the Default, demand that it be remedied and state that the notice is a Notice of Default. When any Default under this Section 7.01 is cured, it ceases.

(c) The Company will deliver to the Trustee, within 30 days after becoming aware of the occurrence of a Default or Event of Default, written notice thereof.

Section 7.02. Acceleration.

If an Event of Default (other than an Event of Default specified in clause (9) or (10) of Section 7.01(a)) shall occur and be continuing with respect to this Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare all unpaid principal of and accrued interest on all Securities to be due and payable, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any such declaration, such principal and interest shall become due and payable immediately. If an Event of Default specified in clause (9) or (10) of Section 7.01(a) occurs and is continuing, then all the Securities shall ipso facto become and be due and payable immediately in an amount equal to the principal amount of the Securities, together with accrued and unpaid interest, if any, to the date the Securities become due and payable, without any declaration or other act on the part of the

Trustee or any Holder. Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders of the Securities by appropriate judicial proceedings.

After a declaration of acceleration with respect to the Securities, but before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Securities Outstanding, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if:

(a) the Company has paid or deposited with the Trustee a sum sufficient to pay

(1) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,

(2) all overdue interest on all Outstanding Securities,

(3) the principal of any Outstanding Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Securities, and

(4) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities;

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

(c) all Events of Default, other than the non-payment of principal of and interest on the Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 7.13. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

Notwithstanding the foregoing, to the extent elected by the Company, the sole remedy for an Event of Default relating to the failure by the Company to comply with the provisions of Section 5.02 of this Indenture shall, for the first 365 days after the occurrence of such an Event of Default, consist exclusively of the right to receive special interest (“Special Interest”) on the Securities at an annual rate equal to 0.50% of the principal amount of the Securities. Such Special Interest shall be paid semi-annually in arrears, with the first semi-annual payment due on the first Interest Payment Date following the date on which such Special Interest began to accrue on the Securities. Special Interest shall accrue on all Outstanding Securities from and including the date on which an Event of Default relating to a failure to comply with the provisions of Section 5.02 shall first occur to but not including the 365th day thereafter (or such earlier date on which such Event of Default shall have been cured or waived). On such 365th day (or earlier, if the Event of Default relating to the failure to comply with Section 5.02 is cured or waived prior to such 365th day), such Special Interest shall cease to accrue and, if the Event of Default relating to the failure to comply with Section 5.02 shall not have been cured or waived prior to such 365th day, the Securities shall be subject to acceleration as provided in this Section 7.02. The provisions of this paragraph shall not affect the rights of Holders in the event of the occurrence of any other Event of Default. In the event the Company shall not elect to pay Special Interest upon an Event of Default resulting from the failure of the Company to comply with the provisions of Section 5.02, the Securities shall be subject to acceleration as provided above in this Section 7.02.

If the Company shall elect to pay Special Interest in connection with an Event of Default relating to its failure to comply with the requirements of Section 5.02, (1) the Company shall notify all Holders and the Trustee and Paying Agent of such election on or before the close of business on the date on which such Event of Default shall first occur, and (2) all references herein to interest accrued or payable as of any date shall include any Special Interest accrued or payable as of such date as provided in this Section 7.02.

Section 7.03. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Company covenants that if:

(a) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or

(b) default is made in the payment of the principal of any Security at the Stated Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and interest, with interest upon the overdue principal and, to the extent that payment of such interest shall be legally enforceable, upon overdue installments of interest, at the rate borne by the Securities; and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

If an Event of Default occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders under this Indenture or any Guarantee by such appropriate private or judicial proceedings as the Trustee shall deem most effectual to protect and enforce such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in any Guarantee or in aid of the exercise of any power granted herein, or to enforce any other proper remedy, subject however to Section 7.12. No recovery of any such judgment upon any property of the Company or any Guarantor shall affect or impair any rights, powers or remedies of the Trustee or the Holders.

Section 7.04. Trustee May File Proofs of Claim.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(a) to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Securities and to file such other papers or documents as may be

necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(b) to 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 such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay 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 8.07.

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 7.05. Trustee May Enforce Claims Without Possession of Securities.

All rights of action and claims under this Indenture, the Securities or the Guarantees may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered.

Section 7.06. Application of Money Collected.

Any money collected by the Trustee pursuant to this Article 7 or otherwise on behalf of the Holders or the Trustee pursuant to this Article 7 or through any proceeding or any arrangement or restructuring in anticipation or in lieu of any proceeding contemplated by this Article 7 and any money or other property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied, subject to applicable law, in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

FIRST: To the payment of all amounts due the Trustee (or any predecessor trustee) under Section 8.07;

SECOND: To the payment of the amounts then due and unpaid upon the Securities for principal and interest, in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and interest; and

THIRD: The balance, if any, to the Person or Persons entitled thereto, including the Company, provided that all sums due and owing to the Holders and the Trustee have been paid in full as required by this Indenture.

Section 7.07. Limitation on Suits.

No Holder of any Securities shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture or the Securities, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless

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

(b) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as trustee hereunder;

(c) such Holder or Holders have offered to the Trustee a reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request;

(d) the Trustee for 15 days after its receipt of such notice, request and offer (and if requested, provision) of indemnity has failed to institute any such proceeding; and

(e) no direction inconsistent with such written request has been given to the Trustee during such 15-day period by the Holders of a majority in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture or any Security, except in the manner provided in this Indenture and for the equal and ratable benefit of all the Holders.

Section 7.08. Unconditional Right of Holders to Receive Payment and to Convert.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of the principal amount, interest, Fundamental Change Purchase Price, if any, or Special Interest, if any, in respect of the Securities held by such Holder, on or after the respective due dates expressed in the Securities and this Indenture (whether upon repurchase or otherwise), and to convert such Security in accordance with Article 4, and to bring suit for the enforcement of any such payment on or after such respective due dates or for the right to convert in accordance with Article 4, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder.

Section 7.09. Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case the Company, any other obligor on the Securities, the Trustee and the Holders shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted.

Section 7.10. Rights and Remedies Cumulative.

No right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 7.11. Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 7 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 7.12. Control by Holders.

The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities shall have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, provided that:

(a) such direction shall not be in conflict with any rule of law or with this Indenture, expose the Trustee to personal liability, or be unduly prejudicial to Holders not joining therein; and

(b) subject to the provisions of Section 315 of the TIA, the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 7.13. Waiver of Past Defaults.

Subject to Section 7.08, the Holders of a majority in aggregate principal amount of the Securities then Outstanding by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except an uncured Default or Event of Default in the payment of the principal of or any accrued but unpaid interest on any Security, an uncured failure by the Company to convert any Securities into Common Stock and cash, as applicable, or any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 10.02, cannot be modified or amended without the consent of the Holder of each Security affected. When a Default or Event of Default is waived, it is cured and ceases to exist.

Section 7.14. Undertaking for Costs.

All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good

faith of the claims or defenses made by such party litigant, but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest on, any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of purchase pursuant to Article 3 hereof, on the Fundamental Change Purchase Date).

Section 7.15. Remedies Subject to Applicable Law.

All rights, remedies and powers provided by this Article 7 may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law in the premises, and all the provisions of this Indenture are intended to be subject to all applicable mandatory provisions of law which may be controlling in the premises and to be limited to the extent necessary so that they will not render this Indenture invalid, unenforceable or not entitled to be recorded, registered or filed under the provisions of any applicable law.

ARTICLE 8

TRUSTEE

Section 8.01. Duties of Trustee.

(a) In case 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 own affairs;

(d) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, 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;

(i) the permissive rights of the Trustee enumerated herein shall not be construed as duties of the Trustee;

The Trustee, any Paying Agent, Registrar, Conversion Agent or any other agent of the Company, in its individual or any other capacity, may become the owner or pledgee of Securities, with the same rights it would have if it were not the Trustee, Paying Agent, Registrar, Conversion Agent or such other agent and, subject to TIA Sections 310 and 311, may otherwise deal with the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not the Trustee, Paying Agent, Registrar, Conversion Agent or such other agent.

Section 8.06. Money Held in Trust.

All moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by mandatory provisions of law.

Section 8.07. Compensation and Indemnification of Trustee and Its Prior Claim.

The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee shall be entitled to, such compensation as the parties shall agree in writing from time to time for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust) and the Company covenants and agrees to pay or reimburse the Trustee and each predecessor Trustee upon its request for all reasonable expenses,

disbursements and advances incurred or made by or on behalf of the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its counsel and of all agents and other persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its gross negligence or willful misconduct. The Company also covenants and agrees to indemnify the Trustee and each predecessor Trustee for, and to hold it harmless against, any claim, loss, liability, tax, assessment or other governmental charge (other than taxes applicable to the Trustee’s compensation hereunder) or expense incurred without gross negligence or willful misconduct on its part, arising out of or in connection with the acceptance or administration of this Indenture or the trusts hereunder and its duties hereunder, including enforcement of this Section 8.07 and also including any liability which the Trustee may incur as a result of failure to withhold, pay or report any tax, assessment or other governmental charge, and the costs and expenses of defending itself against or investigating any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The obligations of the Company under this Section 8.07 to compensate and indemnify the Trustee and each predecessor Trustee and to pay or reimburse the Trustee and each predecessor Trustee for reasonable expenses, disbursements and advances shall constitute an additional obligation hereunder and, together with the lien referred to in the next sentence, shall survive the satisfaction and discharge, and termination for any reason, of this Indenture and the resignation or removal of the Trustee and each predecessor Trustee. To secure the Company’s obligations in this Section 8.07, the Trustee shall have a lien prior to the Securities on all money and property held or collected by the Trustee, other than money or property held in trust for the payment of principal of or interest on particular Securities.

“Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

Without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 7.01(a)(9) or Section 7.01(a)(10), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable Federal or State bankruptcy, insolvency or other similar law.

Section 8.08. Conflicting Interests.

The Trustee shall comply with the provisions of Section 310(b) of the TIA. For purposes of Section 310(b)(1) of the TIA and to the extent permitted thereby, the Trustee, in its capacity as trustee in respect of the Securities, shall not be deemed to have a conflicting interest arising from its capacity as trustee in respect of the 5.750% Notes or the 6.375% Notes issued pursuant to the indenture dated as of July 21, 2005, among the Company, the guarantors named therein, and The Bank of New York as trustee, or any indenture or indentures pursuant to which other securities or certificates of interest or participation in other securities of the Company are outstanding if the requirements for such exclusion set forth in said Section 310(b)(1) are met. Nothing herein shall preclude the Trustee from making the application referred to in the penultimate paragraph of Section 310(b) of the TIA.

Section 8.09. Trustee Eligibility.

There shall at all times be a Trustee hereunder which shall be eligible to act as trustee under TIA Section 310(a) and which shall have a combined capital and surplus of at least $50,000,000, to the extent there is an institution eligible and willing to serve. If the Trustee does not have a Corporate Trust Office in The City of New York, the Trustee may appoint an agent in The City of New York reasonably acceptable to the Company to conduct any activities which the Trustee may be required under this

Indenture to conduct in The City of New York. If such Trustee publishes reports of condition at least annually, pursuant to law or to the requirements of federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section 8.09, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 8.09, the Trustee shall resign immediately in the manner and with the effect hereinafter specified in this Article 8.

Section 8.10. Resignation and Removal; Appointment of Successor Trustee.

(a) No resignation or removal of the Trustee and no appointment of a successor trustee pursuant to this Article 8 shall become effective until the acceptance of appointment by the successor trustee under Section 8.11.

(b) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by giving written notice thereof to the Company. Such resignation shall take effect upon the appointment of a successor Trustee and the acceptance of such appointment by such successor Trustee. If the instrument of acceptance by a successor Trustee required by Section 811 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation or of any removal of the Trustee as hereinafter provided, the resigning or removed Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities.

(c) The Trustee may be removed at any time for any cause or for no cause by an Act of the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities, delivered to the Trustee and to the Company.

(d) If at any time:

(1) the Trustee shall fail to comply with the provisions of TIA Section 310(b) after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months,

(2) the Trustee shall cease to be eligible under Section 8.09 and shall fail to resign after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or

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

then, in any case, (i) the Company may remove the Trustee, or (ii) subject to Section 7.14, the Holder of any Security who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.

(e) If the Trustee shall be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, the Company shall promptly appoint a successor trustee and shall comply with the applicable requirements of Section 8.11. If, within 60 days after such removal or incapability, or the occurrence of such vacancy, the Company has not appointed a successor Trustee, a successor trustee shall be appointed by the Act of the Holders of a majority in principal amount of the Outstanding Securities delivered to the Company and the retiring Trustee. Such successor trustee so appointed shall forthwith upon its acceptance of such appointment become the successor trustee. If no successor trustee shall have been so appointed by the Company or the Holders of the Securities and accepted appointment in the manner hereinafter provided, the Trustee or the Holder of any Security who has been a bona fide Holder for at least six months may, subject to Section 7.14, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor trustee.

(f) The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor trustee by mailing written notice of such event by first-class mail, postage prepaid, to the Holders of Securities as their names and addresses appear in the register of the Registrar. Each notice shall include the name of the successor trustee and the address of its Corporate Trust Office or agent hereunder.

Section 8.11. Acceptance of Appointment by Successor.

(a) Every successor trustee appointed hereunder shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee as if originally named as Trustee hereunder; but, nevertheless, on the written request of the Company or the successor trustee, upon payment of its charges pursuant to Section 8.07 then unpaid, such retiring Trustee shall pay over to the successor trustee all moneys at the time held by it hereunder, subject nevertheless to its lien provided for in Section 8.07, and shall execute and deliver an instrument transferring to such successor trustee all such rights, powers, trusts and duties. Upon request of any such successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers.

(b) No successor trustee with respect to the Securities shall accept appointment as provided in this Section 8.11 unless at the time of such acceptance such successor trustee shall be eligible to act as trustee under the provisions of TIA Section 310(a) and this Article 8 and shall have a combined capital and surplus of at least $50,000,000 and have a Corporate Trust Office or an agent selected in accordance with Section 8.09.

(c) Upon acceptance of appointment by any successor trustee as provided in this Section 8.11, the Company shall give notice thereof to the Holders of the Securities, by mailing such notice to such Holders at their addresses as they shall appear on the Security Register. If the acceptance of appointment is substantially contemporaneous with the appointment, then the notice called for by the preceding sentence may be combined with the notice called for by Section 8.10. If the Company fails to give such notice within 10 days after acceptance of

appointment by the successor trustee, the successor trustee shall cause such notice to be given at the expense of the Company.

Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Trustee (including the trust created by this Indenture) shall be the successor of the Trustee hereunder, provided that such Person shall be eligible under TIA Section 310(a) and this Article 8 and shall have a combined capital and surplus of at least $50,000,000 and have a Corporate Trust Office or an agent selected in accordance with Section 8.09, without the execution or filing of any paper or any further act on the part of any of the parties hereto.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee and deliver such Securities so authenticated; and, in case at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor trustee; and in all such cases such certificate shall have the full force which it is anywhere in the Securities or in this Indenture provided that the certificate of the Trustee shall have; provided that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Securities in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

Section 8.13. Preferential Collection of Claims Against Company.

If and when the Trustee shall be or become a creditor of the Company (or other obligor under the Securities), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against the Company (or any such other obligor). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

Section 8.14. Reports By Trustee.

(a) Within 60 days after June 15 of each year commencing with the first June 15 after the issuance of Securities, the Trustee, if so required under the TIA, shall transmit by mail to all Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report dated as of such June 15 in accordance with and with respect to the matters required by TIA Section 313(a). The Trustee shall also transmit by mail to all Holders, in the manner and to the extent provided in TIA Section 313(c), a brief report in accordance with and with respect to the matters required by TIA Section 313(b)(2).

(b) A copy of each report transmitted to Holders pursuant to this Section 8.14 shall, at the time of such transmission, be mailed to the Company and filed with each national securities exchange, if any, upon which the Securities are listed and also with the SEC. The Company will notify the Trustee promptly if the Securities are listed on any national securities exchange.

Section 9.03. Reinstatement.

If the Trustee, any Paying Agent or any Conversion Agent is unable to apply any money in accordance with Section 9.02 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, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee, such Paying Agent or such Conversion Agent is permitted to apply all such money in accordance with Section 9.02; provided, however, that if the Company has made any payment of the principal of or interest on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee, such Paying Agent or such Conversion Agent.

ARTICLE 11

NOTE GUARANTEES

Section 11.01. Guarantees.

(a) Each Guarantor, hereby jointly and severally, absolutely, unconditionally and irrevocably guarantees the Securities and obligations of the Company hereunder and thereunder, and guarantees to each Holder of a Security authenticated and delivered by the Trustee, and to the Trustee on behalf of such Holder, that (i) the principal of and interest on the Securities will be paid in full when due, whether at the Final Maturity Date or a Fundamental Change Purchase Date, by acceleration or otherwise (including, without limitation, the amount that would become due but for the operation of any automatic stay provision of any Bankruptcy Law), together with interest on the overdue principal, if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be paid in full or performed or observed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Securities or of any such other obligations, the same will be paid in full when due or performed or observed in accordance with the terms of the extension or renewal, whether at the Final Maturity Date or a Fundamental Change Purchase Date, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 11.03 hereof.

Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of Securities with respect to any provisions hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(b) Each Guarantor hereby waives (to the extent permitted by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of

insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to Securities except by complete performance of the obligations contained therein, this Indenture and such Guarantee. Each Guarantor acknowledges that the Guarantee is a guarantee of payment and not of collection. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal or interest on such Security, whether at the Final Maturity Date or a Fundamental Change Purchase Date, by acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Security, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities, to collect interest on the Securities, or to enforce or exercise any other right or remedy with respect to the Securities, such Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or any Guarantor , any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) subject to this Article 11, the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 7 hereof for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article 7 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

(d) Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Company’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Securities, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(e) To evidence its Guarantee, each Guarantor hereby agrees that a Notation of Guarantee substantially in the form attached as Exhibit B hereto will be endorsed by an Officer

of such Guarantor on each Security authenticated and delivered to the Trustee and that this Indenture or a supplemental indenture to this Indenture substantially in the form of Exhibit C hereto will be executed on behalf of such Guarantor by one of its Officers. Each Guarantor hereby agrees that its Guarantee will remain in full force and effect notwithstanding any failure to endorse on each Security a Notation of Guarantee. The delivery of any Security by the Trustee, after the authentication thereof hereunder, will be deemed to constitute due delivery of the Notation of Guarantee set forth in this Indenture by the Guarantors.

Section 11.02. Severability.

In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 11.03. Limitation of Liability.

Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee by each such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Holders and each such Guarantor hereby irrevocably agree that the obligations of such Guarantor under its Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to this Article 11, result in the obligations of such Guarantor under its Guarantee constituting such fraudulent transfer or conveyance.

Section 11.04. Contribution.

In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree, inter se, that in the event any payment or distribution is made by any Guarantor under a Guarantee, such Guarantor will be entitled to a contribution from any other Guarantor in a pro rata amount based on the net assets of each Guarantor determined in accordance with GAAP.

Section 11.05. Subrogation.

Each Guarantor shall be subrogated to all rights of Holders against the Company in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 11.01; provided, however, that if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Company under this Indenture or the Securities shall have been paid in full.

Section 11.06. Reinstatement.

Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that the Guarantee provided for in Section 11.01 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof, of any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the Company upon the bankruptcy or insolvency of the Company or any Guarantor.

Section 11.07. Release of a Guarantor.

Notwithstanding the foregoing, each Guarantee by a Guarantor of the Securities shall provide by its terms that it shall be automatically and unconditionally released and discharged upon (i) any sale, exchange or transfer, to any Person not an Affiliate of the Company, of all of the Company’s Capital Stock in, or all or substantially all the assets of, such Guarantor, which transaction is in compliance with the terms of this Indenture and pursuant to which transaction such Guarantor is released from all guarantees, if any, by it of other Indebtedness of the Company or any of its Subsidiaries, (ii) such Subsidiary ceasing to be a guarantor of the 5.750% Notes and of the 6.375% Notes (other than by reason of a payment under a guarantee by any Subsidiary) or (iii) payment in full of all principal and interest on the Securities.

Section 11.08. Benefits Acknowledged.

Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its respective Guarantee and waiver pursuant to its respective Guarantee is knowingly made in contemplation of such benefits.

In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice when mailed to a Holder in the aforesaid manner shall be conclusively deemed to have been received by such Holder whether or not actually received by such Holder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

In case by reason of the suspension of regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event as required by any provision of this Indenture, then any method of giving such notice as shall be reasonably satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice.

If the Company mails any notice to a Holder of a Security, it shall mail a copy to the Trustee and each Registrar, Paying Agent and Conversion Agent.

Section 12.03. Disclosure of Names and Addresses of Holders.

Holders may communicate pursuant to TIA Section 312(b) with other Holders with respect to their rights under this Indenture or the Securities, and the Trustee shall comply with TIA Section 312(b). The Company, the Trustee, the Registrar and any other Person shall have the protection of TIA 312(c). Further, every Holder of Securities, by receiving and holding the same, agrees with the Company and the Trustee that neither the Company nor the Trustee or any agent of either of them shall be held accountable by reason of the disclosure of any information as to the names and addresses of the Holders in accordance with TIA Section 312, regardless of the source from which such information was derived, and that the

Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under TIA Section 312.

Section 12.04. Compliance Certificates and Opinions.

(a) Upon any application or request by the Company to the Trustee to take any action under any provision of this Indenture (except for the issuance of the Securities on the Issue Date) and as may be requested by the Trustee, the Company shall furnish to the Trustee an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with, and an Opinion of Counsel stating that in the opinion of such counsel all such conditions precedent, if any, have been complied with, except that, in the case of any such application or request as to which the furnishing of such certificates or opinions is specifically required by any provision of this Indenture relating to such particular application or request, no additional certificate or opinion need be furnished.

(b) Every certificate or Opinion of Counsel with respect to compliance with a condition or covenant provided for in this Indenture shall include:

(1) a statement that the Person signing such certificate or opinion has read and understands such covenant or condition and the definitions herein relating thereto;

(2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(3) a statement that, in the opinion of such Person, such Person has made such examination or investigation as is necessary to enable such Person to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(4) a statement as to whether, in the opinion of such Person, such condition or covenant has been complied with.

Section 12.05. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section 12.05.

(b) The ownership of Securities shall be proved by the register maintained by the Primary Registrar.

(c) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the transfer thereof or in exchange therefor or in lieu thereof, in respect of anything done, suffered or omitted to be done by the Trustee, any Paying Agent or Conversion Agent, or the Company or any other obligor of the Securities in reliance thereon, whether or not notation of such action is made upon such Security.

(d) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(e) If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to a Board Resolution, fix in advance a record date for the determination of such Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. Notwithstanding TIA Section 316(c), any such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not more than 30 days prior to the first solicitation of Holders generally in connection therewith and no later than the date such first solicitation is completed.

(f) If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for purposes of determining whether Holders of the requisite proportion of Securities then Outstanding have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for this purpose the Securities then Outstanding shall be computed as of such record date; provided that no such request, demand, authorization, direction, notice, consent, waiver or other Act by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after such record date.

(g) For purposes of this Indenture, any action by the Holders which may be taken in writing may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

Section 12.06. Benefits of Indenture.

Nothing in this Indenture or in the Securities or the Guarantees, express or implied, shall give to any Person (other than the parties hereto and their successors hereunder, any Paying Agent and the Holders) any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 12.07. Legal Holidays.

In any case where any Interest Payment Date, Fundamental Change Purchase Date or Final Maturity Date of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Securities) payment of interest or principal need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, Fundamental Change Purchase Date or Final Maturity Date, and no interest shall accrue with respect to such payment for the period from and after such Interest Payment Date, Fundamental Change Purchase Date or Final Maturity Date, as the case may be, to the next succeeding Business Day.

Section 12.08. Governing Law; Waiver of Trial by Jury.

THIS INDENTURE, THE SECURITIES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

EACH PARTY HERETO, AND EACH HOLDER OF A SECURITY BY ITS ACCEPTANCE THEREOF, HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS INDENTURE.

Section 12.09. No Adverse Interpretation of Other Agreements.

This Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or a Subsidiary of the Company. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

Section 12.10. No Personal Liability of Directors, Officers, Employees and Stockholders.

No director, officer, employee, stockholder, incorporator or agent of the Company or any Guarantor, as such, will have any liability for any obligations of the Company or such Guarantor under the Securities, the Guarantees, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Securities by accepting a Security waives and releases all such liability.

Section 12.11. Successors and Assigns.

All covenants and agreements in this Indenture by the Company and the Guarantors shall bind their respective successors and assigns, whether so expressed or not.

Section 12.12. Multiple Counterparts.

The parties may sign multiple counterparts of this Indenture. Each signed counterpart shall be deemed an original, but all of them together represent the same agreement.

Section 12.13. Separability Clause.

In case any provision in this Indenture or in the Securities or Guarantees shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

[FORM OF REVERSE SIDE OF SECURITY]

Mylan Laboratories Inc.

__% Senior Convertible Notes due ____

1. Interest

Mylan Laboratories Inc., a Pennsylvania corporation (the “Company”, which term shall include any successor company under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of ___% per annum. The Company shall pay interest semiannually on ___and ___of each year (each an “Interest Payment Date”), commencing ___, ___. Interest payable on any Interest Payment Date shall include interest accrued from and including the immediately preceding Interest Payment Date (or if none, from and including ___, ___) to but excluding the relevant Interest Payment Date. Cash interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any payment required to be made on a day that is not a Business Day shall be made on the next succeeding Business Day with the same force and effect as if made on such day and without any interest in respect of the delay. The Company shall, to the fullest extent permitted by law, pay interest in immediately available funds on overdue principal and interest at the rate of ___% per annum, compounded semiannually, which interest shall accrue from the date such overdue amount was originally due to the day preceding the date payment of such amount, including interest thereon, has been made or duly provided for.

Any reference herein to interest accrued or payable as of any date shall include any Special Interest that may be payable in accordance with the provisions of Section 7.02 of the Indenture.

2. Method of Payment

The Company shall pay interest on this Security (except defaulted interest) to the Person who is the Holder of this Security at the close of business on ___or ___, as the case may be (each, a “Regular Record Date”) next preceding the related Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect payment of principal. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts.

3. Paying Agent, Registrar and Conversion Agent

Initially, The Bank of New York (the “Trustee”, which term shall include any successor trustee under the Indenture hereinafter referred to) will act as Paying Agent, Registrar and Conversion Agent. The Company may change any Paying Agent, Registrar or Conversion Agent without notice to the Holders. The Company or any of its Affiliates may, subject to certain limitations set forth in the Indenture, act as Paying Agent.

4. Indenture

This Security is one of a duly authorized issue of Securities of the Company designated as its ___% Senior Convertible Notes Due ___(the “Securities”), issued under an Indenture, dated as of ___, ___(together with any supplemental indentures thereto, the “Indenture”), among the Company, the Guarantors as defined therein and the Trustee. The terms of this Security include those stated in the Indenture and those required by or made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date of the Indenture. This Security is

A-3

subject to all such terms, and the Holder of this Security is referred to the Indenture and the TIA for a statement of them. The Securities are limited to $___aggregate principal amount ($___aggregate principal amount if the Underwriters exercise their over-allotment option in full). The Indenture does not limit other debt of the Company, secured or unsecured.

Capitalized terms not otherwise defined herein have the meaning ascribed to such terms in the Indenture.

5. Purchase of Securities at Option of Holder Upon a Fundamental Change

Upon a Fundamental Change, at the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase for cash all or any part specified by the Holder (so long as the principal amount of such part is $1,000 or an integral multiple of $1,000) of the Securities held by such Holder on the date specified by the Company in accordance with the provisions of Article 3 of the Indenture. The purchase price of any Securities so purchased shall equal 100% of the principal amount thereof together with accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Purchase Date. If the Fundamental Change Purchase Date falls on a day that is after the Regular Record Date and on or prior to the corresponding Interest Payment Date, interest, accrued and unpaid hereon to, but not including, the applicable Fundamental Change Purchase Date, will be paid to the Holder in whose name such Security is registered at the close of business on the Regular Record Date immediately preceding the applicable Fundamental Change Purchase Date.

6. Conversion

Subject to and upon compliance with the provisions of the Indenture and upon the occurrence of the events specified in the Indenture, the Holder may surrender for conversion all or any portion of this Security that is in an integral multiple of $1,000. Upon conversion, the Holder shall be entitled to receive the consideration specified in the Indenture. No fractional share of Common Stock shall be issued upon conversion of a Security. Instead, the Company shall pay a cash adjustment as provided in the Indenture. The initial Conversion Rate of the Securities shall be ___shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in accordance with the provisions of Article 4 of the Indenture. If a Holder converts all or any portion of this Security in connection with the occurrence of certain Fundamental Change transactions, the Conversion Rate shall be increased in the manner and to the extent described in Section 4.01(i) of the Indenture.

Securities surrendered for conversion (in whole or in part) during the period from the close of business on any Regular Record Date to the opening of business on the next succeeding Interest Payment Date shall be accompanied by payment by the Holders of such Securities in funds to the Conversion Agent acceptable to the Company of an amount equal to the interest payable on such corresponding Interest Payment Date; provided that no such payment need be made: (1) in connection with a conversion following the Regular Record Date preceding the Final Maturity Date; (2) if the Company has specified a Fundamental Change Purchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or (3) to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such Security.

A Security in respect of which a Holder has submitted a Fundamental Change Purchase Notice may be converted only if such Holder validly withdraws such Fundamental Change Purchase Notice in accordance with the terms of the Indenture.

A-4

7. Denominations, Transfer, Exchange

The Securities are in registered form, without coupons, in denominations of $1,000 principal amount and integral multiples of $1,000 principal amount. A Holder may register the transfer of or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture.

8. Persons Deemed Owners

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

9. Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee and any Paying Agent will pay the money back to the Company, subject to the provisions of the Indenture. After that, Holders entitled to money must look to the Company for payment as general creditors.

10. Amendment, Supplement and Waiver

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

11. Successor Entity

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

12. Defaults and Remedies

An Event of Default shall occur upon the occurrence of any of the events specified in Section 7.01(a) of the Indenture. Subject to the provisions of the penultimate paragraph of Section 7.02(c) of the Indenture, if an Event of Default shall occur and be continuing with respect to the Securities (other than an Event of Default specified in clause (9) or (10) of Section 7.01(a) of the Indenture), the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then Outstanding may, and the Trustee at the request of such Holders shall, declare all unpaid principal of and accrued interest on all Securities to be due and payable, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Securities). Upon any such declaration, such principal and interest shall become due and payable immediately. If an Event of Default specified in clauses (9) or (10) of Section 7.01(a) of the Indenture occurs and is continuing, then all the Securities shall ipso facto become and be due and payable immediately in an amount equal to the principal amount of the Securities, together with accrued and

A-5

unpaid interest, if any, to the date the Securities become 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 Outstanding, by written notice to the Company and the Trustee, may rescind and annul an acceleration and its consequences if: (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (1) all sums paid or advanced by the Trustee under the Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (2) all overdue interest on all Outstanding Securities, (3) the principal of any Outstanding Securities which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Securities, and (4) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Securities; (b) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (c) all Events of Default, other than the non-payment of principal of and interest on the Securities which have become due solely by such declaration of acceleration, have been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereon.

Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power. The Trustee may, in accordance with the provisions of the Indenture, withhold from Holders notice of any continuing Default (except a Default in payment of principal or interest or to deliver amounts owing upon conversion) if and so long as it determines that withholding notice is in their interests. The Company is required to file periodic certificates with the Trustee as to the Company’s compliance with the Indenture and knowledge or status of any Default.

13. Trustee Dealings With the Company

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

14. No Recourse Against Others

No director, officer, employee, stockholder, incorporator or agent of the Company, as such, will have any liability for any obligations of the Company under the Securities, the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Securities by accepting a Security waives and releases all such liability.

15. Authentication

[FORM OF NOTATION OF GUARANTEE]

Each of the undersigned (collectively, the “Guarantors”) have unconditionally guaranteed, jointly and severally (such guarantee by each Guarantor being referred to herein as the “Guarantee”) (i) the due and punctual payment of the principal of and interest on the Securities when they become due, whether at the Final Maturity Date, a Fundamental Change Purchase Date, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal and interest, if any, on the Securities, to the extent lawful, and the due and punctual performance and observance of all other obligations of the Company to the Holders or the Trustee all in accordance with the terms set forth in Article 11 of the Indenture and (ii) in case of any extension of time of payment or renewal of any Securities or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.
