The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture is initially limited to $250,000,000, except for Securities authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of other Securities pursuant to Section 2.03, 2.04, 2.08, 2.09, 2.10, 2.11, 2.13, 6.07, 10.05, 11.03, or 12.01; provided that additional Securities may be issued in an unlimited aggregate principal amount from time to time thereafter as set forth pursuant to Section 2.04. The Securities shall be issuable in denominations of $1,000 or multiples thereof.

(b) The Securities shall mature on November 15, 2026 unless earlier converted, redeemed or repurchased in accordance with the provisions hereof.

(c) Interest on the Securities shall accrue from and including the date specified on the face of such Securities until the principal thereof is paid or made available for payment. Interest shall be payable semiannually in arrears on May 15 and November 15 in each year, commencing May 15, 2007.

(d) A Holder of any Security at 5:00 p.m., New York City time, on a Regular Record Date shall be entitled to receive interest (including any Additional Interest), on such Security on the corresponding Interest Payment Date, notwithstanding the conversion of such Securities at any time after the close of business on such Regular Record Date. Securities surrendered for conversion during the period after 5:00 p.m., New York City time, on any Regular Record Date to 9:00 a.m., New York City time, on the corresponding Interest Payment Date must be accompanied by payment of an amount equal to the interest (including any Additional Interest) that the Holder is to receive on the Securities. Notwithstanding the foregoing, no such payment of interest (including any Additional Interest) need be made by any converting Holder (i) if the Company

has specified a Redemption Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, (ii) 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 (iii) to the extent of any overdue interest (including any Additional Interest) existing at the time of conversion of such Security. Except as described above, no interest or Additional Interest on converted Securities will be payable by the Company on any Interest Payment Date subsequent to the date of conversion, and delivery of shares of Common Stock or the combination of cash and shares of Common Stock, if applicable, pursuant to Article 12 hereunder, together with any cash payment for any fractional share, upon conversion will be deemed to satisfy in full the Company’s obligation to pay the principal amount of the Securities and accrued and unpaid interest and Additional Interest, if any, to, but not including, the related Conversion Date.

(e) Principal of, interest (including Additional Interest, if any) and premium, if any, on, Global Securities shall be payable to DTC in immediately available funds.

(f) Principal of, and any premium on, Definitive Securities shall be payable at the office or agency of the Company maintained for such purpose, which initially shall be the corporate trust office of the Trustee. Interest (including Additional Interest, if any), on Definitive Securities will be payable (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Securities and (ii) to Holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Registrar not later than the relevant Regular Record Date, by wire transfer in immediately available funds to such Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

Section 2.02. Form of Securities.

(a) Except as otherwise provided pursuant to this Section 2.02, the Securities are issuable in fully registered form without coupons in substantially the form of Exhibit A hereto, with such applicable legends as are provided for in Section 2.03. The Securities are not issuable in bearer form. The terms and provisions contained in the form of Security shall constitute, and are hereby expressly made, a part of this Indenture and to the extent applicable, the Company, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. Any of the Securities may have such letters, numbers or other marks of identification and such notations, legends and endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or

as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Securities may be listed or designated for issuance, or to conform to usage.

(b) The Securities shall be issued initially in the form of one or more permanent Global Securities, with the applicable legends as provided in Section 2.03. Each Global Security shall be duly executed by the Company and authenticated and delivered by the Trustee, and shall be registered in the name of DTC or its nominee and retained by the Trustee, as Securities Custodian, at its corporate trust office, for credit to the accounts of the Agent Members holding the Securities evidenced thereby. 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 Trustee, as Securities Custodian, and of DTC or its nominee, as hereinafter provided.

Section 2.03. Legends. Each Security issued hereunder shall, upon issuance, bear the legend set forth in Section 2.03(i), and each Common Stock certificate representing shares of the Common Stock issued upon conversion of any Security issued hereunder, shall, upon issuance, unless as otherwise set forth below, bear the legend set forth in Section 2.03(ii) (each such legend, a “Restricted Securities Legend”), and such legend shall not be removed except as provided in Section 2.03(iii). Each Security that bears or is required to bear the Restricted Securities Legend set forth in Section 2.03(i) (together with each Common Stock certificate representing shares of the Common Stock issued upon conversion of such Security that bears or is required to bear the Restricted Securities Legend set forth in Section 2.03(ii), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.03 (including the Restricted Securities Legend set forth below), and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, shall be deemed to have agreed to be bound by all such restrictions on transfer.

As used in Section 2.03, the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security.

(i) Restricted Securities Legend for Securities. Except as provided in Section 2.03(iii), any certificate evidencing such Security (and all Securities issued in exchange therefor or substitution thereof, other than stock certificates representing shares of the Common Stock, if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.03(ii), if applicable) shall bear a Restricted Securities Legend in substantially the following form:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE

“SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH SECURITY, EXCEPT (A) TO THE COMPANY; (B) UNDER A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT; (C) ONLY IN THE CASE OF THIS SECURITY, TO A PERSON THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A ADOPTED UNDER THE SECURITIES ACT) THAT IS PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF ANOTHER QUALIFIED INSTITUTIONAL BUYER AND TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, ALL IN COMPLIANCE WITH RULE 144A (IF AVAILABLE); OR (D) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (2) IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY FURNISH TO THE TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED PURSUANT TO THE INDENTURE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.”

(ii) Restricted Securities Legend for the Common Stock Issued Upon Conversion of the Securities. Each stock certificate representing Common Stock issued upon conversion of Securities bearing a Restricted Securities Legend will, subject to the availability of a Shelf Registration Statement and registration thereunder as set forth in the Registration Rights Agreement, bear the following legend:

“THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT WILL NOT RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY, EXCEPT (A) TO THE COMPANY; (B) UNDER A REGISTRATION STATEMENT THAT HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT; OR (C) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (2) IT WILL, PRIOR TO ANY TRANSFER OF THIS SECURITY FURNISH TO THE

TRANSFER AGENT AND THE ISSUER SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS MAY BE REQUIRED TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.”

(iii) Removal of the Restricted Securities Legends. The Restricted Securities Legend may be removed from any Security or any Common Stock certificate representing shares of the Common Stock issued upon conversion of any Security if there is delivered to the Company such satisfactory evidence, which may include an opinion of independent counsel, as may be reasonably required by the Company, that neither such legend nor the restrictions on transfer set forth therein are required to ensure that transfers of such Security or shares of the Common Stock issued upon conversion of Securities, as the case may be, will not violate the registration requirements of the Securities Act or the qualification requirements under any state securities laws. Upon provision of such satisfactory evidence, at the written direction of the Company, (x) in the case of a Security, the Trustee shall authenticate and deliver in exchange for such Security another Security or Securities having an equal aggregate principal amount that do not bear such legend or (y) in the case of a Common Stock certificate representing shares of the Common Stock, the transfer agent for the Common Stock shall authenticate and deliver in exchange for the Common Stock certificate or certificates representing such shares of Common Stock bearing such legend, one or more new Common Stock certificates representing a like aggregate number of shares of Common Stock that do not bear such legend. If the Restricted Securities Legend has been removed from a Security or Common Stock certificates representing shares of the Common Stock issued upon conversion of any Security as provided above, no other Security issued in exchange for all or any part of such Security, or no other Common Stock certificates issued in exchange for such Common Stock, shall bear such legend, unless the Company has reasonable cause to believe that such other Security is a “restricted security” (or such shares of Common Stock are “restricted securities”) within the meaning of Rule 144 and instructs the Trustee in writing to cause a Restricted Securities Legend to appear thereon.

Any Security (or Security issued in exchange or substitution therefor) as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.03(i) as set forth therein have been satisfied may, upon surrender of such Security for exchange to the Registrar in accordance with the provisions of Section 2.08, be exchanged for a new Security or Securities, of like tenor and aggregate principal amount, which shall not bear the Restricted Securities Legend required by Section 2.03(i).

Any Common Stock certificate representing shares of Common Stock issued upon conversion of any Security as to which the conditions for removal of the Restricted Securities Legend set forth in Section 2.03(ii) have been satisfied may, upon surrender of the Common Stock certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer agent for the Common Stock, be exchanged for a new Common Stock certificate or certificates representing a like aggregate number of shares of Common Stock, which shall not bear the Restricted Securities Legend.

(iv) Global Security Legend. Each Global Security shall also bear the following legend (the “Global Security Legend”) on the face thereof:

“UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, 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 DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO IN THE TERMS OF SECURITIES ATTACHED HERETO.”

(v) Legend for Definitive Securities. Definitive Securities, in addition to the legend set forth in Section 2.03(i), will also bear a legend substantially in the following form:

“THIS SECURITY WILL NOT BE ACCEPTED IN EXCHANGE FOR A BENEFICIAL INTEREST IN A GLOBAL SECURITY UNLESS THE HOLDER OF THIS SECURITY, SUBSEQUENT TO SUCH EXCHANGE, WILL HOLD NO SECURITIES.”

Section 2.04. Execution and Authentication. One Officer shall sign the Securities for the Company by manual or facsimile signature. If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Indenture. A Security shall be dated the date of its authentication.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities executed by the Company in an unlimited aggregate principal amount to the Trustee for authentication, together with a written order of the Company signed by two Officers or by an Officer and an Assistant Secretary of the Company (the “Company Order”) for the authentication and delivery of such Securities, and the Trustee in accordance with such Company Order shall authenticate and deliver such Securities as in this Indenture provided and not otherwise. All Securities issued on the Issue Date shall be identical in all respects with any such Securities authenticated and delivered thereafter, other than issue dates, the date from which interest accrues, appropriate CUSIP numbers or other identifying notations and any changes relating thereto. Notwithstanding anything to the contrary contained in this Indenture, subject to Section 2.12, all Securities issued under this Indenture shall vote and consent together on all matters as one class and no series of Securities will have the right to vote or consent as a separate class on any matter.

The Trustee may appoint an agent (the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. Initially, the Trustee will act as the Authenticating Agent. Any such instrument shall be evidenced by an instrument signed by a Trust Officer of the Trustee, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by the Authenticating Agent. An Authenticating Agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands.

In case the Company, pursuant to Article 4, shall be consolidated or merged with or into, or shall convey, transfer or lease all or substantially all of its properties and assets to, any Person, and the Successor Company, if not the Company, shall have executed an indenture supplemental hereto with the Trustee

pursuant to Article 4, any of the Securities authenticated or delivered prior to such consolidation, merger, conveyance, transfer or lease may, from time to time, at the request of the Successor Company, be exchanged for other Securities executed in the name of the Successor Company with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Securities surrendered for such exchange and of like principal amount; and the Trustee, upon Company Order of the Successor Company, shall authenticate and deliver Securities as specified in such order for the purpose of such exchange. If Securities shall at any time be authenticated and delivered in any new name of a Successor Company pursuant to this Section 2.04 in exchange or substitution for or upon registration of transfer of any Securities, such Successor Company, at the option of the Holders but without expense to them, shall provide for the exchange of all Securities at the time outstanding for Securities authenticated and delivered in such new name.

Section 2.05. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange (the “Securities Register”). The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent and the term “Registrar” includes any co-registrar.

The Company shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of each such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 8.07. The Company or any of its domestically organized, wholly owned Subsidiaries may act as Paying Agent, Registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent for the Securities. The Company may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (i) acceptance of any appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Registrar or successor Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Company and the Trustee.

Section 2.06. Paying Agent to Hold Money in Trust. By no later than 11:00 a.m., New York City time, on the date on which any principal of, interest (including any Additional Interest) and premium, if any, on any Security is due and payable, the Company shall deposit with the Paying Agent a sum sufficient in immediately available funds to pay such principal, interest (including any Additional Interest) and premium, if any, when due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of, interest (including any Additional Interest) or premium, if any, on the Securities and shall notify the Trustee in writing of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent (other than the Trustee) to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section 2.06, the Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy, reorganization or similar proceeding with respect to the Company, the Trustee shall serve as Paying Agent for the Securities.

Section 2.07. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, or to the extent otherwise required under the TIA, the Company shall furnish or cause the Registrar to furnish to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders and the Company shall otherwise comply with TIA § 312(a).

Section 2.08. General Provisions Relating to Transfer and Exchange. The Securities are issuable only in registered form. A Holder may transfer a Security only by written application to the Registrar stating the name of the proposed transferee and otherwise complying with the terms of this Indenture. No such transfer shall be effected until, and such transferee shall succeed to the rights of a Holder only upon, final acceptance and registration of the transfer by the Registrar in the Securities Register. Furthermore, any Holder of a Global Security shall, by acceptance of such Global Security, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by the Holder of such Global Security (or its agent) and that ownership of a beneficial interest in the Global Security shall be required to be reflected in a book-entry.

When Securities are presented to the Registrar with a request to register the transfer or to exchange them for an equal aggregate 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 (including that such Securities are duly endorsed or accompanied by a written instrument of transfer duly executed by the Holder thereof or by an attorney who is authorized in writing to act on behalf of the Holder). Subject to Section 2.04, to permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. No service charge shall be made for any registration of transfer or exchange or redemption of the Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge required by law or permitted under the terms of this Indenture.

Neither the Company nor the Registrar shall be required to exchange or register a transfer of any Securities:

(a) selected for redemption under Article 6 or, if a portion of any Security is selected for redemption, the portion thereof selected for redemption;

(b) surrendered for conversion or, if a portion of any Security is surrendered for conversion, the portion thereof surrendered for conversion; or

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 beneficial owners of 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 2.09. Book-Entry Provisions for the Global Securities. (a) The Global Securities initially shall:

(i) be registered in the name of DTC (or a nominee thereof);

(ii) be delivered to the Trustee as Securities Custodian;

(iii) bear the Restricted Securities Legend set forth in Section 2.03(i); and

(iv) bear the Global Security Legend set forth in Section 2.03(iv).

Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by DTC, or the Trustee as its custodian, or under such Global Security, and DTC may be treated by the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing contained herein shall prevent the Company, the Guarantors, the Trustee or any agent of the Company, the Guarantors or Trustee from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and the Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

(b) The Holder of a Global Security 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.

(c) A Global Security may not be transferred, in whole or in part, to any Person other than DTC (or a nominee thereof) or to a successor thereof (or such successor’s nominee), and no such transfer to any such other Person may be registered. Beneficial interests in a Global Security may be transferred in accordance with the rules and procedures of DTC and the provisions of Section 2.10.

(d) If at any time:

(i) DTC notifies the Company in writing that it is unwilling or unable to continue to act as depositary for the Global Securities and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such notice;

(ii) DTC ceases to be registered as a “clearing agency” under the Exchange Act and a successor depositary for the Global Securities is not appointed by the Company within 90 days of such cessation;

(iii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of the Definitive Securities under this Indenture in exchange for all or any part of the Securities represented by a Global Security or Global Securities, subject to the procedures of DTC; or

(iv) an Event of Default has occurred and is continuing and the Registrar has received a request from DTC for the issuance of Definitive Securities in exchange for such Global Security or Global Securities;

the Securities Custodian shall surrender such Global Security or Global Securities to the Trustee for cancellation and the Company shall execute, and the Trustee, upon receipt of an Officers’ Certificate and Company Order for the authentication and delivery of Securities, shall authenticate and deliver in exchange for such Global Security or Global Securities, Definitive Securities in an aggregate principal amount equal to the aggregate principal amount of such Global Security or Global Securities. Such Definitive Securities shall be registered in such names as DTC (or any nominee thereof) shall identify in writing as the beneficial owners of the Securities represented by such Global Security or Global Securities.

(e) Notwithstanding the foregoing, in connection with any transfer of beneficial interests in a Global Security to the beneficial owners thereof pursuant to Section 2.09(d), the Registrar shall reflect on its books and records the date and a decrease in the principal amount of such Global Security in an amount equal to the principal amount of the beneficial interests in such Global Security to be transferred.

Section 2.10. Special Transfer Provisions. Unless a Security is no longer a Restricted Security, the following provisions shall apply to any sale, pledge or other transfer of such Securities:

(a) Transfer of Securities to a QIB. The following provisions shall apply with respect to the registration of any proposed transfer of Securities to a QIB:

(i) If the Securities to be transferred consist of a beneficial interest in the Global Securities, the transfer of such interest may be effected only through the book-entry systems maintained by DTC.

(ii) If the Securities to be transferred consist of Definitive Securities, the Registrar shall register the transfer if such transfer is being made by a proposed transferor who has checked the box provided for on the form of Security stating (or has otherwise advised the Company and the Registrar in writing) that the sale has been made in compliance with the provisions of Rule 144A to a transferee who has signed a certification stating or has otherwise advised the Company and the Registrar in writing that:

(A) it is purchasing the Securities for its own account or an account with respect to which it exercises sole investment discretion;

(B) it and any such account is a QIB within the meaning of Rule 144A;

(D) it acknowledges that it has received such information regarding the Company as it has requested pursuant to Rule 144A or has determined not to request such information; and

(E) it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A.

(b) General. By its acceptance of any Security bearing the Restricted Securities Legend, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and agrees that it will transfer such Security only as provided in this Indenture. The Registrar shall not register a transfer of any Security unless such transfer complies with the restrictions on transfer of such Security set forth in this Indenture. The Registrar shall be entitled to receive and rely on written instructions from the Company verifying that such transfer complies with such restrictions on transfer. In connection with any transfer of Securities, each Holder agrees by its acceptance of the Securities to furnish the Registrar or the Company such certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities Act; provided that the Registrar shall not be required to determine (but may rely on a determination made by the Company with respect to) the sufficiency of any such certifications, legal opinions or other information.

The Registrar shall retain copies of all certifications, letters, notices and other written communications received pursuant to Section 2.09 hereof or this Section 2.10. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Section 2.11. Mutilated, Destroyed, Lost or Wrongfully Taken Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the UCC are met, such that the Holder (a) notifies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar has not registered a transfer prior to receiving such notification, (b) makes such request to

the Company or Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the UCC and (c) satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Guarantors, the Trustee, the Paying Agent and the Registrar from any loss which any of them may suffer if a Security is replaced, and, 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 Company Order the Trustee shall authenticate and make available for delivery, in exchange for any such mutilated Security or in lieu of any such destroyed, lost or wrongfully taken Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding.

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

Upon the issuance of any new Security under this Section 2.11, the Company may require the payment by the Holder 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 the Trustee) in connection therewith.

Every new Security issued pursuant to this Section 2.11 in lieu of any mutilated, destroyed, lost or wrongfully taken Security shall constitute an original additional contractual obligation of the Company and any other obligor upon the Securities, whether or not the mutilated, destroyed, lost or wrongfully taken Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and ratably with any and all other Securities duly issued hereunder.

The provisions of this Section 2.11 are 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 wrongfully taken Securities.

Section 2.12. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this Section 2.12 as not outstanding. A Security does not cease to be outstanding in the event the Company or an Affiliate of the Company holds the Security; provided, however, that (i) for purposes of determining which Securities are outstanding for consent or voting purposes hereunder, the provisions of Section 14.06 shall apply and (ii) in determining whether the Trustee shall be protected in making a determination whether the Holders of the requisite principal amount of outstanding Securities are present at a meeting of Holders of Securities for quorum purposes or have

consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, or relying upon any such quorum, consent or vote, only Securities which a Trust Officer of the Trustee actually knows to be held by the Company or an Affiliate of the Company shall not be considered outstanding.

If a Security is replaced or paid pursuant to Section 2.11, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a protected purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Redemption Date or at Stated Maturity, money sufficient to pay all principal, premium, if any, and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest (including any Additional Interest) on them ceases to accrue.

Section 2.13. Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Company may prepare and upon receipt of a Company Order the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and upon receipt of a Company Order the Trustee shall authenticate Definitive Securities. After the preparation of Definitive Securities, the temporary Securities shall be exchangeable for Definitive Securities upon surrender of the temporary Securities at any office or agency maintained by the Company for that purpose and such exchange shall be without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute, and the Trustee shall authenticate and make available for delivery in exchange therefor, one or more Definitive Securities representing an equal principal amount of Securities. Until so exchanged, the Holder of temporary Securities shall in all respects be entitled to the same benefits under this Indenture as a Holder of Definitive Securities.

Section 2.14. Cancellation. The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar, the Conversion Agent and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange, conversion or payment. The Trustee and no one else shall cancel all Securities surrendered for registration of transfer, exchange, conversion, payment or cancellation and dispose of such Securities in accordance with its internal policies and customary procedures including delivery of a certificate describing such Securities disposed of (subject to the record

retention requirements of the Exchange Act). The Company may not issue new Securities to replace Securities it has paid for or converted or delivered to the Trustee for cancellation for any reason other than in connection with a transfer or exchange.

At such time as all beneficial interests in a Global Security have either been exchanged for Definitive Securities, transferred, redeemed, repurchased, converted or canceled, such Global Security shall be returned by the Securities Custodian to the Trustee for cancellation or retained and canceled by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for Definitive Securities, transferred in exchange for an interest in another Global Security, redeemed, repurchased, converted or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

Section 2.15. Payment of Interest; Defaulted Interest. Interest (including any Additional Interest) on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more predecessor Securities) is registered at the close of business on the Regular Record Date for such payment at the office or agency of the Company maintained for such purpose pursuant to Section 2.05.

Any interest on any Security which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 days, shall forthwith cease to be payable to the Holder on the Regular Record Date, and such interest and (to the extent lawful) interest on such interest at the rate borne by the Securities (such interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by the Company at its election, in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on a Special Record Date (as defined below) 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 30 days after such notice) of the proposed payment (the “Special Interest Payment Date”), and at the same time 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 date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to

such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a record date (the “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 Special Interest 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 of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given in the manner provided for in Section 14.02, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in whose names the Securities (or their respective predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b).

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

Subject to the foregoing provisions of this Section 2.15, 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 (including any Additional Interest) accrued and unpaid, and to accrue, which were carried by such other Security.

Section 2.16. Computation of Interest. Interest (including any Additional Interest) on the Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

Section 2.17. CUSIP and ISIN Numbers. The Company in issuing the Securities may use “CUSIP” and “ISIN” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such CUSIP or ISIN numbers. The Company shall promptly notify the Trustee in writing of any change in the CUSIP and ISIN numbers.

Section 3.02. Maintenance of Office or Agency. The Company will maintain an office or agency where the Securities may be presented or surrendered for payment, where, if applicable, the 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 Company will give prompt written notice to the Trustee of any change in the location of any such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served to the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind any 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 other office or agency.

Section 3.05. Compliance Certificate. The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate, one of the signers of which shall be the principal executive officer, principal financial officer or principal accounting officer of the Company, stating that in the course of the performance by the signers of their duties as Officers of the Company they would normally have knowledge of any Default or Event of Default and whether or not the signers know of any Default or Event of Default that occurred during such period.

(i) the amount of such Additional Interest that is payable and (ii) the date on which such Additional Interest is payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no Additional Interest is payable. If the Company has paid Additional Interest directly to the persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment.

Section 3.09. Additional Subsidiary Guarantees. If any of the Company’s Subsidiaries (including a Foreign Subsidiary) that is not already a Guarantor, guarantees any indebtedness of the Company or a Domestic Subsidiary, then such Subsidiary will become a Guarantor and execute and deliver to the Trustee a supplemental indenture in substantially the form attached hereto as Exhibit C, a notation of Subsidiary Guarantee and an Officers’ Certificate and an Opinion of Counsel in accordance with Section 10.06, within 10 Business Days of the date on which it guarantees such indebtedness of the Company or a Domestic Subsidiary. The form of such notation of Subsidiary Guarantee is attached as Exhibit B hereto.

ARTICLE 4

SUCCESSOR COMPANY

Section 4.01. Consolidation, Merger and Sale of Assets. The Company shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its properties and assets to, another Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company, shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the Company under the Securities, this Indenture and, to the extent then still operative, the Registration Rights Agreement;

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

(c) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, stating that such consolidation, merger or transfer and such supplemental indenture, if any, comply with this Indenture.

For purposes of this Section 4.01, the conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, but, in the case of a lease of all or substantially all its properties and assets, the Company will not be released from the obligation to pay the principal of, premium, if any, and interest (including any Additional Interest) on the Securities.

ARTICLE 5

REPORTING OBLIGATIONS

Section 5.01. Reporting Obligations. (a) The Company shall deliver to the Trustee, within 15 days after filing with the SEC, copies of its annual reports and of information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) which the Company is required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

(b) In the event and for as long as the Company is not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act:

(i) it shall continue to provide the Trustee with reports containing substantially the same information as would have been required to be filed with the SEC had the Company continued to have been subject to such reporting requirements and also mail such documents to each Holder at such Holder’s registered address, upon the request of any Holder or beneficial holder of the Securities or the Common Stock issued upon conversion thereof. In such event, such reports shall be provided at the times the Company would have been required to provide reports had it continued to have been subject to Section 13 or 15(d) of the Exchange Act; and

(ii) it shall make available, to each Holder or beneficial holder of Securities or Common Stock in connection with any sale thereof and any prospective purchaser of Securities or Common Stock designated by such Holder or beneficial holder, upon request, the information required pursuant to Rule 144A(d)(4) under the Securities Act and it will take such further action as any Holder or beneficial holder of such Securities or Common Stock may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by Rule 144A, as such Rule may be amended from time to time.

(c) Delivery of reports, information and other documents under this Section 5.01 to the Trustee is for informational purposes only and the Trustee’s

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

Section 5.02. Reporting in Compliance with TIA. The Company also shall comply with the other provisions of Section 314(a) of the Trust Indenture Act.

ARTICLE 6

REDEMPTION OF SECURITIES

Section 6.01. Optional Redemption.

(a) Prior to November 15, 2011, the Securities shall not be redeemable.

(b) On and after November 15, 2011 but prior to November 15, 2013, subject to the terms and conditions of this Article 6, the Company may, at its option, redeem for cash all or a portion of the Securities, at a price (the “Redemption Price”) equal to 100% of the principal amount of Securities to be redeemed, plus accrued and unpaid interest (including any Additional Interest) to but excluding the Redemption Date and a “make-whole” premium pursuant to Section 6.01(d) below, only if the Last Reported Sale Price of the Common Stock is greater than or equal to 135% of the Conversion Price then in effect for at least 20 Trading Days within a period of 30 consecutive Trading Days ending on the Trading Day prior to the date on which the notice of redemption is mailed.

(c) On or after November 15, 2013, subject to the terms and conditions of this Article 6, the Company may, at its option, redeem at any time for cash all or a portion of the Securities, at a Redemption Price equal to 100% of the principal amount of Securities to be redeemed, plus accrued and unpaid interest (including any Additional Interest) to but excluding the Redemption Date.

(d) If the Company redeems Securities pursuant to Section 6.01(b) above, the Company will pay a “make-whole” premium in cash equal to the present value of all remaining scheduled payments of interest on the Securities to be redeemed to but excluding November 15, 2013. The present value of the remaining interest payments will be computed using a discount rate equal to the Treasury Yield.

(e) In the event that the Redemption Date occurs after a Regular Record Date for the payment of interest and on or prior to the related Interest Payment Date, the Redemption Price for any such Securities to be redeemed shall be 100% of the principal amount of such Securities, and accrued and unpaid interest (including any Additional Interest) shall be paid to the Holder on such Regular Record Date.

Section 6.02. Election to Redeem; Notice to Trustee. In case of any redemption at the election of the Company, the Company shall, on or prior to the date that is 15 days prior to the date on which notice is given to the Holders (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be redeemed pursuant to Section 6.03. Any such notice may be cancelled at any time prior to notice of such redemption being mailed to any Holder and shall thereby be void and of no effect.

Section 6.03. Selection by Trustee of Securities to Be Redeemed. If less than all the Securities are to be redeemed at any time pursuant to this Article 6, the particular Securities to be redeemed shall be selected by the Trustee, from the outstanding Securities not previously called for redemption, by lot or on a pro rata basis among the Securities or by such other method as the Trustee shall deem fair and appropriate, including any method required by DTC or any successor depositary (and in such manner as is not prohibited by applicable legal requirements) and which may provide for the selection for redemption of portions of the principal of the Securities; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Security not redeemed to less than $1,000.

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the principal amount of such Security which has been or is to be redeemed.

If any Securities selected for partial redemption are thereafter surrendered for conversion in part before termination of the conversion right with respect to the portion of the Securities so selected, the converted portion of such Securities shall be deemed (so far as may be), solely for purposes of determining the aggregate principal amount of Securities to be redeemed by the Company, to be the portion selected for redemption. Securities which have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. Nothing in this Section 6.03 shall affect the right of any Holder to convert any Securities pursuant to Article 12 before the termination of the conversion right with respect thereto.

Section 6.04. Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 14.02 not less than 30 Scheduled Trading Days nor more than 45 Scheduled Trading Days prior to the Redemption Date, to the Trustee, the Paying Agent and each Holder of Securities to be redeemed. The Trustee shall give notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall deliver to the Trustee an Officers’ Certificate, at least 15 calendar days prior to the date on which notice is required to be given to the Holders (unless shorter notice shall be satisfactory to the Trustee), requesting that the Trustee give such notice at the Company’s expense and setting forth the information to be stated in such notice as provided in the following items.

All notices of redemption shall state:

(a) the Redemption Date;

(b) the Redemption Price;

(c) the then current Conversion Rate and the related Observation Period for conversion of Securities, and provide a statement that the Securities called for redemption may be converted at any time before the close of business on the third Scheduled Trading Day prior to the Redemption Date, and that Holders who wish to convert Securities must comply with the procedures in paragraph 5 of the Securities;

(d) if less than all outstanding Securities are to be redeemed, the identification of the particular Securities (or portion thereof) to be redeemed, as well as the aggregate principal amount of Securities to be redeemed and the aggregate principal amount of Securities to be outstanding after such partial redemption;

(e) in case any Security is to be redeemed in part only, the notice which relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder will receive, without charge, a new Security or Securities of authorized denominations for the principal amount thereof remaining unredeemed;

(f) that on the Redemption Date the Redemption Price will become due and payable upon each such Security, or the portion thereof, to be redeemed, and, unless the Company defaults in making the redemption payment, that interest (including any Additional Interest) on Securities called for redemption (or the portion thereof) will cease to accrue on and after said date;

(g) the place or places where such Securities are to be surrendered for payment of the Redemption Price;

(h) the name and address of the Paying Agent and the Conversion Agent;

(i) that Securities called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

(j) the CUSIP or ISIN number, and that no representation is made as to the accuracy or correctness of the CUSIP or ISIN number, if any, listed in such notice or printed on the Securities; and

(k) the paragraph of the Securities pursuant to which the Securities are to be redeemed.

Section 6.05. Deposit of Redemption Price. Prior to 11:00 a.m., New York City time, on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 2.06) an amount of money sufficient to pay the Redemption Price of all the Securities which are to be redeemed on that date other than Securities or portions of Securities called for redemption that are beneficially owned by the Company and have been delivered by the Company to the Trustee for cancellation.

Section 6.06. Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price, and from and after such date (unless the Company shall default in the payment of the Redemption Price, accrued and unpaid interest (including any Additional Interest) or premium, if any) such Securities shall cease to bear interest or Additional Interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price.

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities.

Section 6.07. Securities Redeemed in Part. Any Security which is to be redeemed only in part (pursuant to the provisions of this Article 6) shall be surrendered at the office or agency of the Company maintained for such purpose pursuant to Section 3.02 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security at the expense of the Company, a new Security or Securities, of any authorized denomination as requested by such Holder, in an aggregate principal

amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered; provided that each such new Security will be in a principal amount of $1,000 or multiple thereof.

ARTICLE 7

DEFAULTS AND REMEDIES

Section 7.01. Events of Default. Each of the following is an “Event of Default”:

(a) default in any payment of interest (including Additional Interest) or premium, if any, on any Security when the same becomes due and payable, and such default continues for a period of 30 days;

(b) default in the payment of the principal of any Security when the same becomes due and payable at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration of acceleration or otherwise;

(c) failure by the Company to comply with its obligation to convert the Securities in accordance with this Indenture, upon exercise of a Holder’s conversion right and such failure continues for a period of 10 days;

(d) failure by the Company to give a Company Notice of the occurrence of a Fundamental Change to Holders pursuant to Section 11.01 or notice of a specified corporate transaction (as described in Section 12.01(a)(iv)) or a notice of a Public Acquirer Change of Control (as described in Section 12.04(c)) to Holders, in each case when due;

(e) failure by the Company to comply with its obligations under Article 4;

(f) failure by the Company for a period of 60 days after written notice from the Trustee or Holders of at least 25% in principal amount of Securities then outstanding has been received to comply with any obligation, covenant or agreement in this Indenture or under the Securities (other than those referred to in Section 7.01(a) through (e) and Section 7.01(g) through (i));

(g) default by the Company or any Subsidiary in the payment of the principal or interest on any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $15,000,000 in the aggregate of the Company and/or any such Subsidiary, whether such indebtedness now exists or shall hereafter be created, resulting in such indebtedness becoming or being declared due and payable, and such acceleration shall not have been rescinded or

annulled within 30 days after written notice of such acceleration has been received by the Company or such Subsidiary from the Trustee (or to the Company and the Trustee from Holders of at least 25% in principal amount of outstanding Securities);

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

(i) commences a voluntary case or proceeding;

(ii) consents to the entry of judgment, decree or order for relief against it in an involuntary case or proceeding;

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property;

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

(v) consents to or acquiesces in the institution of a bankruptcy or an insolvency proceeding against it;

(vi) takes any corporate action to authorize or effect any of the foregoing; or

(vii) takes any comparable action under any foreign laws relating to insolvency;

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

(i) is for relief against the Company or any Significant Subsidiary in an involuntary case;

(ii) appoints a Custodian of the Company for all or substantially all of the Company’s or any Significant Subsidiary’s property; or

(iii) orders the winding up or liquidation of the Company or Significant Subsidiary;

and, in each case, the order or decree or relief remains unstayed and in effect for 90 days; or

(j) except as permitted by this Indenture, any Subsidiary Guarantee shall be held in any final judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Subsidiary Guarantee.

The foregoing will constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is 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.

Notwithstanding the foregoing, a Default under clause (f) or (g) of this Section 7.01 will not constitute an Event of Default until the Trustee notifies the Company (or the Holders of 25% or more in principal amount of the outstanding Securities notify the Company and the Trustee) of the Default in writing and the Company does not cure such Default within the time specified in clause (f) or (g) of this Section 7.01 after receipt of such notice.

Section 7.02. Acceleration. Subject to Section 7.03, if an Event of Default (other than an Event of Default specified in Section 7.01(h) or Section 7.01(i) above) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in outstanding principal amount of the outstanding Securities by notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal of and accrued and unpaid interest, if any, and Additional Interest and premium, if any, on all the Securities to be due and payable. Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest and Additional Interest, if any, shall be due and payable immediately. If an Event of Default specified in Section 7.01(h) or Section 7.01(i) above occurs and is continuing, the principal of and accrued and unpaid interest, if any, and Additional Interest and premium, if any, on all the Securities outstanding shall be immediately due and payable with no further action by the Trustee or the Holders.

Section 7.03. Sole Remedy for Failure to Report. Notwithstanding any other provision of this Indenture, the sole remedy for an Event of Default relating to the failure to comply with the reporting obligations under Article 5 of this Indenture, and for any failure to comply with the requirements of Section 314(a)(1) of the TIA, will for the 365 days after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the principal amount of the Securities at a rate equal to 0.50% per annum. This Additional Interest will be in addition to any Additional Interest that may accrue as a result of a registration default as described in the Registration Rights Agreement and will be payable in the same manner and subject to the same terms as other interest payable under this Indenture. The Additional Interest will accrue on all outstanding Securities from and including the date on which an Event of Default relating to a failure to comply with Article 5 or Section 314(a)(1) of the TIA first occurs to but not excluding the 365^th day thereafter (or such earlier date on which the Event of Default relating to the reporting obligations under Article 5

or Section 314(a)(1) of the TIA shall have been cured or waived). On such 365^th day (or earlier, if the Event of Default relating to such reporting obligations is cured or waived prior to such 365^th day), such Additional Interest will cease to accrue and the Securities will be subject to acceleration and other remedies as provided in this Article 7 if the Event of Default is continuing. For the avoidance of doubt, the provisions of this Section 7.02 will not affect the rights of Holders of Securities in the event of the occurrence of any other Event of Default and will have no effect on the rights of Holders of Securities under the Registration Rights Agreement.

Section 7.04. Other Remedies. If an Event of Default other than an Event of Default specified in Section 7.01(f), occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, interest (including any Additional Interest) or premium, if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

Section 7.05. Waiver of Past Defaults. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may (a) waive, by their consent (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), an existing Default or Event of Default and its consequences except (i) a Default or Event of Default resulting from the non-payment of the principal, interest (including any Additional Interest) or premium, if any, on a Security, (ii) a Default or Event of Default resulting from the failure to deliver, upon conversion, shares of Common Stock or the combination of cash and shares of Common Stock, if any, upon the conversion of the Security or (iii) a Default or Event of Default in respect of a provision that under Section 10.02 cannot be amended without the consent of each Holder affected and (b) rescind any such acceleration with respect to the Securities and its consequences if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than the nonpayment of the principal of, interest (including any Additional Interest) or premium, if any, on the Securities that have become due solely by such declaration of acceleration, have been cured or waived. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right.

Section 7.06. Control by Majority. The Holders of a majority in principal amount of the outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Sections 8.01 and 8.02, that the Trustee determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction.

Section 7.07. Limitation on Suits. Subject to Section 7.08, a Holder may not pursue any remedy with respect to this Indenture or the Securities unless:

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

(b) Holders of at least 25% in principal amount of the outstanding Securities have requested that the Trustee pursue the remedy;

(c) such Holders have offered to the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense to be incurred in compliance with such request;

(d) the Trustee has not complied with such request within 60 days after receipt of the request and the offer of security or indemnity; and

(e) the Holders of a majority in principal amount of the outstanding Securities have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

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

Section 7.08. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture (including, without limitation, Section 7.07), the right of any Holder to receive payment of principal of, interest (including any Additional Interest) or premium, if any, on the Securities held by such Holder, on or after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 7.09. Collection Suit by Trustee. If an Event of Default specified in clauses (a) or (b) of Section 7.01 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest (including any Additional Interest) to the extent lawful) and the amounts provided for in Section 8.07.

Section 7.10. Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company, the Guarantors or its or their respective creditors or properties and, unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter, and may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due to the Trustee under Section 8.07.

Section 7.11. Priorities. If the Trustee collects any money or property pursuant to this Article 7, it shall pay out the money or property in the following order:

FIRST: to the Trustee for amounts due under Section 8.07;

SECOND: to Holders for amounts due and unpaid on the Securities for principal, interest (including any Additional Interest) or premium, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, interest and premium, respectively; and

THIRD: to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 7.11. At least 15 days before such record date, the Company shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid.

Section 7.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under this Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Company, the Trustee, the Guarantors and the Holders will be restored severally and respectively to their former

positions hereunder and thereafter all rights and remedies of the Company, the Trustee, the Guarantors and the Holders will continue as though no such proceeding had been instituted.

Section 7.13. Undertaking of Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 7.13 does not apply to a suit by the Trustee, a suit by the Company, a suit by a Holder pursuant to Section 7.08 or a suit by Holders of more than 10% in outstanding principal amount of the Securities.

ARTICLE 8

TRUSTEE

Section 8.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against loss, liability or expense that might be incurred in compliance with such request or direction.

(b) Except during the continuance of an Event of Default:

(i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates, opinions or orders furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates, opinions or orders which by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

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

(i) this paragraph does not limit the effect of paragraph (b) of this Section 8.01;

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

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 7.06.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 8.01.

(e) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company.

(f) Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur 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 to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(h) Every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section 8.01 and to the provisions of the TIA.

(i) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company.

Section 8.02. Rights of Trustee. Subject to Section 8.01:

(a) The Trustee may conclusively rely on any document (whether in its original or facsimile form) reasonably believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. The Trustee shall receive and retain

financial reports and statements of the Company as provided herein, but shall have no duty to review or analyze such reports or statements to determine compliance under covenants or other obligations of the Company.

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

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers, unless the Trustee’s conduct constitutes willful misconduct or negligence.

(e) The Trustee may consult with counsel of its selection, and the advice or opinion of counsel with respect to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability in respect to any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such counsel.

(f) The Trustee shall not be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) resulting from actions taken in good faith and which the Trustee believes to be authorized or within its rights or powers, unless the Trustee’s conduct constitutes willful misconduct or negligence.

(g) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, Securities Custodian and other Person employed to act hereunder.

(h) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of Officers authorized at such time to take specified actions pursuant to this Indenture.

Section 8.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights. However, the Trustee must comply with Sections 8.10 and 8.11. In addition, the Trustee shall be permitted to engage in transactions with the

Company; provided, however, that if, during the continuance of any Default, the Trustee acquires any conflicting interest the Trustee must (i) eliminate such conflict within 90 days of acquiring such conflicting interest, (ii) apply to the SEC for permission to continue acting as Trustee or (iii) resign.

Section 8.04. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Securities, shall not be accountable for the Company’s use of the proceeds from the Securities, shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee and shall not be responsible for any statement of the Company in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication.

Section 8.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer of the Trustee has actual knowledge thereof, the Trustee shall mail by first class mail to each Holder at the address set forth in the Securities Register notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, interest (including any Additional Interest) or premium, if any, on any Security (including payments pursuant to the optional redemption or required repurchase provisions of such Security, if any), the Trustee may withhold the notice if and so long as it determines in good faith that withholding the notice is in the interests of Holders.

Section 8.06. Reports by Trustee to Holders. As promptly as practicable after each May 15 beginning with the May 15 following the date of this Indenture, and in any event prior to July 1 in each year, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA § 313(a), if required by such TIA § 313(a). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports required by TIA § 313(c).

Section 8.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. In addition to the compensation the Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it. Such expenses shall include the reasonable compensation and out-of-pocket expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Company and the Guarantors, jointly and severally, shall indemnify the Trustee against any and all loss, liability, damages, claims or expense (including reasonable attorneys’ fees and expenses) incurred by it without negligence or bad faith on its part in connection with the administration of this trust and the

performance of its duties hereunder, including the costs and expenses of enforcing this Indenture (including this Section 8.07) and of defending itself against any claims (whether asserted by any Holder, the Company, any Guarantor or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company or any of the Guarantors of its obligations hereunder. The Company and such Guarantor shall defend the claim and the Trustee shall provide reasonable cooperation at the Company’s expense in the defense. The Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel, provided that the Company shall not be required to pay such fees and expenses if it assumes the Trustee’s defense, and, in the reasonable judgment of outside counsel to the Trustee, there is no conflict of interest between the Company or any Guarantor and the Trustee in connection with such defense. The Company and the Guarantors need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith.

To secure the Company’s and the Guarantors’ payment obligations in this Section 8.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, interest (including any Additional Interest) and premium, if any, on particular Securities. Such lien shall survive the satisfaction and discharge of this Indenture. The Trustee’s right to receive payment of any amounts due under this Section 8.07 shall not be subordinate to any other unsecured liability or debt of the Company or any Guarantor.

The Company’s and the Guarantors’ payment obligations pursuant to this Section 8.07 shall survive the discharge of this Indenture. When the Trustee incurs expenses after the occurrence of a Default specified in Section 7.01(h) or Section 7.01(i) with respect to the Company or any Guarantor, the expenses are intended to constitute expenses of administration under any Bankruptcy Law.

Section 8.08. Replacement of Trustee. The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if:

(a) the Trustee fails to comply with Section 8.10;

(b) the Trustee is adjudged bankrupt or insolvent;

(d) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed by the Company or by the Holders of a majority in principal amount of the Securities and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 8.07.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of at least 10% in principal amount of the Securities may petition, at the Company’s expense, any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 8.10, unless the Trustee’s duty to resign is stayed as provided in TIA § 310(b), any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding the replacement of the Trustee pursuant to this Section 8.08, the Company’s obligations under Section 8.07 shall continue for the benefit of the retiring Trustee.

Section 8.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee.

In case at the time such successor or successors by merger, conversion or consolidation 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 to the Trustee; provided that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate Securities in the name of any predecessor Trustee shall only apply to its successor or successors by merger, consolidation or conversion.

Section 8.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding, including the indenture governing the Company’s 6.125% Senior Notes due 2014, if the requirements for such exclusion set forth in TIA § 310(b)(1) are met.

Section 8.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated.

Section 9.01. Discharge of Liability on Securities.

Change Purchase Date or Redemption Date, as the case may be, and if in either case (1) or (2) the Company shall also pay or cause to be paid all other sums payable hereunder by the Company, then this Indenture with respect to the Securities shall cease to be of further effect (except as to (i) remaining rights of registration of transfer, substitution and exchange and conversion of Securities; (ii) rights hereunder of Holders to receive from the Trustee payments of the amounts then due, including interest (including any Additional Interest) or premium, if any, with respect to the Securities and the other rights, duties and obligations of Holders, as beneficiaries hereof solely with respect to the amounts, if any, so deposited with the Trustee; and (iii) the rights, obligations and immunities of the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar under this Indenture with respect to the Securities), and the Trustee, on demand of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel as required by Section 9.03 and at the cost and expense of the Company, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to the Securities; however, the Company hereby agrees to reimburse the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any costs or expenses thereafter reasonably and properly incurred by the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar and to compensate the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar for any services thereafter reasonably and properly rendered by the Trustee, Authenticating Agent, Paying Agent, Conversion Agent and Registrar in connection with this Indenture with respect to the Securities.

Section 9.02. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money to the Holders entitled thereto by reason of any order or judgment of any court of governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture with respect to the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with this Indenture and the Securities to the Holders entitled thereto; provided, however, that if the Company makes any payment of principal amount of, interest (including any Additional Interest) or premium, if any, on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent.

Section 9.03. Officers’ Certificate; Opinion of Counsel. Upon any application or demand by the Company to the Trustee to take any action under Section 9.01, the Company shall furnish to the Trustee an Officers’ Certificate or Opinion of Counsel stating that all conditions precedent, if any, provided for in this Indenture relating to the proposed action have been complied with.

ARTICLE 10

AMENDMENTS

Section 10.01. Without Consent of Holders. The Company, the Guarantors and the Trustee may amend this Indenture, the Securities and the Subsidiary Guarantees without notice to or consent of any Holder:

(a) to cure any ambiguity, omission, defect or inconsistency in this Indenture in a manner that does not individually or in the aggregate adversely affect the rights of any Holder of Securities in any respect;

(b) to comply with Article 4 or Section 13.04 in respect of the assumption by a Successor Company of an obligation of the Company under this Indenture or any successor Guarantor under any Subsidiary Guarantee;

(c) to add Guarantors with respect to the Securities or release Guarantors from Subsidiary Guarantees as provided or permitted by the terms of this Indenture;

(d) to secure the Securities;

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

(f) to comply with any requirement of the SEC in connection with the qualification of this Indenture under the TIA;

(h) to add to any Events of Default for the benefit of Holders of Securities;

(i) to make any change that does not materially adversely affect the rights of any Holder; or

(j) to conform the text of this Indenture, any Subsidiary Guarantee or the Securities to the “Description of Notes” section of the Offering Memorandum.

After an amendment under this Section 10.01 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 10.01.

Section 10.02. With Consent of Holders. The Company, the Guarantors and the Trustee may amend this Indenture, the Subsidiary Guarantees and the Securities without notice to any Holder but with the written or electronic consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities), and subject to the provisions of Section 7.05 past Defaults or compliance with the provisions of this Indenture or the Securities issued hereunder or related Subsidiary Guarantees may be waived with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Holder affected, an amendment or waiver may not:

(a) reduce the percentage in aggregate principal amount of Securities whose Holders must consent to an amendment or waive any past default;

(b) reduce the rate of or extend the stated time for payment of interest, including Additional Interest, or premium, on any Security;

(d) otherwise impair the right of any Holder to receive payment of principal of, interest (including any Additional Interest) or premium, if any, on such Holder’s Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(e) make any change that impairs or adversely affects the conversion rights of any Securities;

(f) release any Guarantor from any of its obligations under its Subsidiary Guarantee or this Indenture, except in accordance with this Indenture;

(g) reduce the Redemption Price, the Fundamental Change Purchase Price or the Purchase Price payable upon the redemption or repurchase or conversion of any Security or amend or modify in any manner adverse to Holders of the Securities the Company’s obligation to make such payments;

(h) make any Security payable in currency other than that stated in the Security (it being understood that all references to cash in this Indenture and the Securities are to U.S. legal tender); or

(i) make any changes to the amendment provisions which require each Holder’s consent or to the waiver provisions.

It shall not be necessary for the consent of the Holders under this Section 10.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. A consent to any amendment or waiver under this Indenture by any Holder of the Securities given in connection with a tender or exchange of such Holder’s Securities will not be rendered invalid by such tender or exchange.

After an amendment under this Section 10.02 becomes effective, the Company shall mail to Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 10.02.

Section 10.03. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Securities shall comply with the TIA as then in effect.

Section 10.04. Revocation and Effect of Consents and Waivers. A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective or otherwise in accordance with any related solicitation documents. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver shall become effective upon receipt by the Trustee of the requisite number of written or electronic consents under Section 10.01 or 10.02, as applicable.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall become valid or effective more than 120 days after such record date.

Section 10.05. Notation on or Exchange of Securities. If an amendment changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in

exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment.

Section 10.06. Trustee to Sign Amendments. The Trustee shall sign any amendment authorized pursuant to this Article 10 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to receive and (subject to Sections 8.01 and 8.02) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

ARTICLE 11

PURCHASE AT THE OPTION OF HOLDERS UPON A FUNDAMENTAL

CHANGE; PURCHASE AT THE OPTION OF HOLDERS

Section 11.01. Purchase at the Option of the Holder Upon a Fundamental Change. If a Fundamental Change shall occur at any time, each Holder shall have the right, at such Holder’s option, to require the Company to purchase any or all of such Holder’s Securities on a date specified by the Company that is no later than the 35^th calendar day after the date of the Company Notice of the occurrence of such Fundamental Change (subject to extension to comply with applicable law, as provided in Section 11.03(d)) (the “Fundamental Change Purchase Date”). The Company shall purchase such Securities at a price (the “Fundamental Change Purchase Price”), which shall be paid in cash, equal to 100% of the principal amount of the Securities to be purchased plus accrued and unpaid interest, including any Additional Interest, to but excluding the Fundamental Change Purchase Date, unless the Fundamental Change Purchase Date is between a Regular Record Date and the Interest Payment Date to which it relates, in which case the Fundamental Change Purchase Price shall equal 100% of the principal amount of Securities to be purchased and accrued and unpaid interest, including Additional Interest, shall be paid to the Holder of record on the Regular Record Date.

(a) Notice of Fundamental Change. The Company, or at its request (which must be received by the Paying Agent at least three Business Days (or such lesser period as agreed to by the Paying Agent) prior to the date the Paying Agent is requested to give such notice as described below) the Paying Agent, in the name of and at the expense of the Company, shall mail to all Holders and the Trustee a Company Notice of the occurrence of a Fundamental Change and of the purchase right arising as a result thereof, including the information required by Section 11.03(a) hereof, on or before the 20^th calendar day after the occurrence of such Fundamental Change. The Company shall promptly furnish to the Paying Agent a copy of such Company Notice.

(b) Exercise of Option. For a Security to be so purchased at the option of the Holder, such Holder must deliver to the Paying Agent such Security duly endorsed for transfer, together with a written notice of purchase (a “Fundamental Change Purchase Notice”) in the form entitled “Form of Fundamental Change Purchase Notice” attached to the Security duly completed, on or before the Business Day immediately preceding the Fundamental Change Purchase Date, subject to extension to comply with applicable law. The Fundamental Change Purchase Notice shall state:

(i) if certificated, the certificate numbers of the Securities which the Holder shall deliver to be purchased, or if not certificated, such notice must comply with appropriate DTC procedures;

(ii) the portion of the principal amount of the Securities which the Holder shall deliver to be purchased, which portion must be $1,000 in principal amount or a multiple thereof; and

(iii) that such Securities shall be purchased as of the Fundamental Change Purchase Date pursuant to the terms and conditions specified in paragraph 4 of the Securities and in this Indenture.

(c) Procedures. The Company shall purchase from a Holder, pursuant to this Section 11.01, Securities if the principal amount of such Securities is $1,000 or a multiple of $1,000 if so requested by such Holder.

Any purchase by the Company contemplated pursuant to the provisions of this Section 11.01 shall be consummated by the delivery of the Fundamental Change Purchase Price to be received by the Holder promptly following the later of the Fundamental Change Purchase Date or the time of book-entry transfer or delivery of the Securities.

Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Fundamental Change Purchase Notice contemplated by this Section 11.01 shall have the right at any time prior to the close of business on the Business Day prior to the Fundamental Change Purchase Date to withdraw such Fundamental Change Purchase Notice (in whole or in part) by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.03(b).

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

At or before 11:00 a.m. (New York City time) on the Fundamental Change Purchase Date, the Company shall deposit with the Paying Agent (or if the

Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate Fundamental Change Purchase Price of the Securities to be purchased pursuant to this Section 11.01. Payment by the Paying Agent of the Fundamental Change Purchase Price for such Securities shall be made promptly following the later of the Fundamental Change Purchase Date or the time of book-entry transfer or delivery of such Securities. If the Paying Agent holds, in accordance with the terms of this Indenture, cash sufficient to pay the Fundamental Change Purchase Price of such Securities on the Fundamental Change Purchase Date, then, on and after such date, such Securities shall cease to be outstanding and interest (including any Additional Interest), on such Securities shall cease to accrue, whether or not book-entry transfer of such Securities is made or such Securities are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Fundamental Change Purchase Price and previously accrued and unpaid interest (including any Additional Interest), upon delivery or transfer of the Securities). Nothing herein shall preclude any withholding tax required by law.

The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held by the Paying Agent for the payment of the Fundamental Change Purchase Price and shall notify the Trustee of any default by the Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to deliver all cash held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee.

Section 11.02. Purchase of Securities at the Option of the Holder.

(a) A Holder shall have the option to require the Company to purchase any outstanding Securities on each of November 15, 2013, November 15, 2016 and November 15, 2021 (each, a “Purchase Date”), at a price (the “Purchase Price”) which shall be paid in cash, equal to 100% of the principal amount of the Securities to be repurchased plus any accrued and unpaid interest, including any Additional Interest, to but excluding the Purchase Date, upon:

(i) delivery to the Paying Agent by the Holder of a written notice of purchase (a “Purchase Notice”) at any time from the opening of business on the date that is 20 Business Days prior to the relevant Purchase Date until the close of business on the second Business Day prior to such Purchase Date, stating:

(A) if certificated, the certificate numbers of the Securities which the Holder will deliver to be purchased, or, if not certificated, the Purchase Notice must comply with appropriate DTC procedures;

(B) the portion of the principal amount of the Securities which the Holder will deliver to be purchased, which portion must be $1,000 in principal amount or a multiple thereof;

(C) that such Securities shall be purchased by the Company as of the Purchase Date pursuant to the terms and conditions specified in paragraph 4 of the Securities and in this Indenture; and

(ii) delivery or book-entry transfer of such Securities to the Paying Agent (together with all necessary endorsements) at the offices of the Paying Agent, such delivery or transfer being a condition to receipt by the Holder of the Purchase Price therefor; provided, however, that such Purchase Price shall be so paid pursuant to this Section 11.02 only if the Securities so delivered or transferred to the Paying Agent shall conform in all respects to the description thereof in the related Purchase Notice.

(b) The Company shall purchase from a Holder, pursuant to this Section 11.02, Securities if the principal amount of such Securities is $1,000 or a multiple of $1,000 if so requested by such Holder.

(c) Any purchase by the Company contemplated pursuant to the provisions of this Section 11.02 shall be consummated by the delivery of the Purchase Price to be received by the Holder promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of the Securities.

(d) Notwithstanding anything herein to the contrary, any Holder delivering to the Paying Agent the Purchase Notice contemplated by this Section 11.02 shall have the right at any time prior to the close of business on the Business Day prior to the Purchase Date to withdraw such Purchase Notice (in whole or in part) by delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 11.03(b).

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

(f) At or before 11:00 a.m. (New York City time) on the Purchase Date, the Company shall deposit with the Paying Agent (or if the Company or an Affiliate of the Company is acting as the Paying Agent, shall segregate and hold in trust) cash sufficient to pay the aggregate Purchase Price of the Securities to be

purchased pursuant to this Section 11.02. Payment by the Paying Agent of the Purchase Price for such Securities shall be made promptly following the later of the Purchase Date or the time of book-entry transfer or delivery of such Securities. If the Paying Agent holds, in accordance with the terms of this Indenture, cash sufficient to pay the Purchase Price of such Securities on the Purchase Date, then, on and after such date, such Securities shall cease to be outstanding and interest (including any Additional Interest) on such Securities shall cease to accrue, whether or not book-entry transfer of such Securities is made or such Securities are delivered to the Paying Agent, and all other rights of the Holder shall terminate (other than the right to receive the Purchase Price and previously accrued interest (including any Additional Interest) upon delivery or transfer of the Securities). Nothing herein shall preclude any withholding tax required by law.

(g) The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash held by the Paying Agent for the payment of the Purchase Price and shall notify the Trustee of any default by the Company in making any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the cash held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to deliver all cash held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the cash delivered to the Trustee.

Section 11.03. Further Conditions and Procedures for Purchase at the Option of the Holder Upon a Fundamental Change and Purchase of Securities at the Option of the Holder.

The Company shall send notices (each, a “Company Notice”) to the Holders, the Trustee, the Paying Agent and beneficial owners as required by applicable law, not less than 20 Business Days prior to each Purchase Date, or on or before the 20^th calendar day after the occurrence of the Fundamental Change, as the case may be (each such date of delivery, a “Company Notice Date”).

At the Company’s request, made at least five Business Days prior to the date upon which such notice is to be mailed, and at the Company’s expense, the Paying Agent shall give the Company Notice in the Company’s name; provided, however, that, in all cases, the text of the Company Notice shall be prepared by the Company.

(b) Adequacy and Effect of Purchase Notice or Fundamental Change Purchase Notice; Withdrawal; Effect of Event of Default. The Company shall reasonably determine whether the Purchase Notice or Fundamental Change Purchase Notice delivered by the relevant Holders satisfies the conditions set out in Section 11.02(a), Section 11.01(b) and Section 11.03 for such notices. The Company’s determination under this Section 11.03(b) will be binding and conclusive, absent manifest error.

Upon receipt by the Company of the Purchase Notice or Fundamental Change Purchase Notice specified in Section 11.02(a) or Section 11.01(b), as applicable, the Holder of the Securities in respect of which such Purchase Notice or Fundamental Change Purchase Notice, as the case may be, was given shall (unless such Purchase Notice or Fundamental Change Purchase Notice is withdrawn as specified in the following two paragraphs) thereafter be entitled to receive solely the Purchase Price or Fundamental Change Purchase Price with respect to such Securities. Such Purchase Price or Fundamental Change Purchase Price shall be paid by the Paying Agent to such Holder promptly following the later of (x) the Purchase Date or the Fundamental Change Purchase Date, as the case may be, with respect to such Securities (provided the conditions in this Article 11 have been satisfied) and (y) the time of delivery or book-entry transfer of such Securities to the Paying Agent by the Holder thereof in the manner required by Section 11.02 or Section 11.01, as applicable.

(i) the principal amount of the Securities with respect to which such notice of withdrawal is being submitted;

(ii) if certificated, the certificate number of the Securities in respect of which such notice of withdrawal is being submitted, or, if not certificated, the written notice of withdrawal must comply with appropriate DTC procedures; and

(iii) the principal amount, if any, of such Securities which remains subject to the original Purchase Notice or Fundamental Change Purchase Notice, as the case may be, and which has been or shall be delivered for purchase by the Company.

There shall be no purchase of any Securities pursuant to Section 11.02 or Section 11.01 if an Event of Default has occurred and is continuing (other than a default that is cured by the payment of the Purchase Price or Fundamental Change Purchase Price, as the case may be). The Paying Agent shall promptly return to the respective Holders thereof any Securities (x) with respect to which a Purchase Notice or Fundamental Change Purchase Notice, as the case may be, has been withdrawn in compliance with this Indenture, or (y) held by it during the continuance of an Event of Default (other than a default that is cured by the payment of the Purchase Price or Fundamental Change Purchase Price, as the case may be) in which case, upon such return, the Purchase Notice or Fundamental Change Purchase Notice with respect thereto shall be deemed to have been withdrawn.

(c) Securities Purchased in Part. Any Securities that are to be purchased only in part shall be surrendered at the office of the Paying Agent (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing) and the Company shall execute and the Trustee or the Authenticating Agent shall authenticate and deliver to the Holder of such Securities, without service charge, a new Security or Securities, of any authorized denomination as requested by such Holder in aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Securities so surrendered which is not purchased.

Exchange Act, if applicable; (b) file the related Schedule TO (or any successor schedule, form or report) under the Exchange Act, if applicable; and (c) otherwise comply with all applicable federal and state securities laws so as to permit the rights and obligations under Section 11.02 or Section 11.01 to be exercised in the time and in the manner specified in Section 11.02 or Section 11.01.

(e) Repayment to the Company. Subject to applicable abandoned property laws, the Trustee and the Paying Agent shall return to the Company any cash or property that remains unclaimed, as provided in paragraph 8 of the Securities, together with interest that the Trustee or Paying Agent, as the case may be, has expressly agreed in writing to pay, if any, that is held by them for the payment of a Purchase Price or Fundamental Change Purchase Price, as the case may be; provided, however, that to the extent that the aggregate amount of cash or property deposited by the Company pursuant to Section 11.01(c) or Section 11.02(f), as applicable, exceeds the aggregate Purchase Price or Fundamental Change Purchase Price, as the case may be, of the Securities or portions thereof which the Company is obligated to purchase as of the Purchase Date or the Fundamental Change Purchase Date, as the case may be, then promptly on and after the Business Day following the Purchase Date or Fundamental Change Purchase Date, as the case may be, the Trustee and the Paying Agent shall return any such excess to the Company together with interest that the Trustee or Paying Agent, as the case may be, has expressly agreed in writing to pay, if any.

(f) Officers’ Certificate. At least five Business Days before the Company Notice Date, the Company shall deliver an Officers’ Certificate to the Trustee specifying whether the Company desires the Trustee to give the Company Notice required by Section 11.03(a) herein.

ARTICLE 12

CONVERSION

Section 12.01. Conversion of Securities. (a) Right to Convert. Subject to the procedures for conversion set forth in this Article 12, a Holder may convert its Securities on or prior to the close of business on the Business Day immediately preceding Stated Maturity at the Conversion Rate when one or more of the conditions specified below are met and during the related specified period. Whenever the Securities shall become convertible upon one or more of the conditions stated in clauses (i), (ii), (iv)(A), (iv)(B) or (iv)(C) below, the Company or, at the Company’s request, the Trustee in the name and at the expense of the Company, shall notify the Holders of the event triggering such convertibility in the manner provided in Section 14.02 and, in the case of one or more conditions stated in clauses (iv)(B) or (iv)(C), the Company shall also publish a notice in accordance with Section 11.03(a). For the avoidance of doubt, the Trustee has no duty to determine if Securities have become convertible, and

its only obligation is to notify Holders of such at the Company’s request. Whenever the Securities shall become convertible upon the condition stated in clause (iii), notice of the event triggering such convertibility shall be given in accordance with the provisions of Section 6.04. Any notice so given shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice.

(i) Conversion Upon Satisfaction of Sale Price Condition. A Holder may surrender all or a portion of its Securities for conversion during any fiscal quarter (and only during such fiscal quarter) commencing after March 31, 2007 if the Last Reported Sale Price for the Common Stock for at least 20 Trading Days during the period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is greater than or equal to 135% of the Conversion Price in effect on such last Trading Day.

(ii) Conversion Upon Satisfaction of Trading Price Condition. Prior to November 15, 2013, a Holder may surrender its Securities for conversion during the five Business Day period after any 10 consecutive Trading Day period (the “Measurement Period”) in which the Trading Price per $1,000 principal amount of Securities, as determined following a request by a Holder in accordance with the procedures set forth in this Section 12.01(a)(ii), for each Trading Day of the Measurement Period was less than 95% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate for such Trading Day. In connection with any conversion in accordance with this Section 12.01(a)(ii), the Trustee shall have no obligation to determine the Trading Price of the Securities unless requested by the Company; and the Company shall have no obligation to make such request unless a Holder provides the Company with reasonable evidence that the Trading Price per $1,000 principal amount of Securities would be less than 95% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate. Promptly after receiving such evidence, 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 Securities for any Trading Day is greater than or equal to 95% of the product of the Last Reported Sale Price of the Common Stock and the applicable Conversion Rate.

(iii) Conversion Upon Notice of Redemption. If the Company calls any or all of the Securities for Redemption, a Holder may surrender for conversion all or a portion of its Securities called for redemption at any time prior to the close of business on the third Scheduled Trading Day prior to the related Redemption Date, even if the Securities are not

otherwise convertible at such time, after which time a Holder’s right to convert will expire unless the Company defaults in the payment of the Redemption Price. For the avoidance of doubt, if the Company gives two or more notices of redemption such that the Observation Periods applicable to the relevant Redemption Dates overlap, the Observation Period based on the first notice of redemption that is given shall be applicable to such Securities.

(iv) Conversion Upon Specified Corporate Transactions.

(A) If the Company elects to (1) distribute to all holders of Common Stock any rights or warrants entitling them to purchase, for a period expiring within 45 days after the Ex-Dividend Date of the distribution, shares of Common Stock at a price per share less than the average of the Last Reported Sale Price of Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution, or (2) distribute to all holders of Common Stock assets, debt securities or rights to purchase securities of the Company, which distribution has a per share Fair Market Value, as determined by the Company’s Board of Directors, exceeding 15% of the Last Reported Sale Price on the Trading Day immediately preceding the Ex-Dividend Date for such distribution, then, in each case, the Company must notify the Holders of such distribution and of their rights under this clause (A), in the manner provided in Section 14.02, at least 35 Scheduled Trading Days prior to the Ex-Dividend Date for such distribution. Once the Company has given such notice, Holders may surrender Securities for conversion at any time until the earlier of 5:00 p.m., New York City time, on the Business Day immediately prior to such Ex-Dividend Date or the Company’s announcement that such distribution will not take place even if the Securities are not otherwise convertible at such time. Notwithstanding the foregoing, Holders may not surrender Securities for conversion if the Holders participate (as a result of holding the Securities, and at the same time as holders of Common Stock participate) in any of the transactions described in this Section 12.01(a)(iv) as if such Holders of the Securities held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of Securities held by such Holder, without having to convert the Securities.

(B) If the Company is party to a transaction described in clause (2) of the definition of Fundamental Change (after

giving effect to the proviso set forth in the definition thereof relating to Publicly Traded Securities) or a combination, merger, binding share exchange or sale, lease or other transfer of all or substantially all of the Company’s and its Subsidiaries’ assets, taken as a whole, in each case pursuant to which Common Stock would be converted into cash, securities and/or other property that does not also constitute a Fundamental Change, the Company must notify Holders of such an event and of their rights under this clause (B), in the manner provided in Section 14.02, at least 35 Scheduled Trading Days prior to the anticipated effective date for such transaction. Once the Company has given such notice, Holders may surrender Securities for conversion at any time until seven Scheduled Trading Days after the actual effective date of such transaction or, if later, the related Fundamental Change Purchase Date.

(C) A Holder may surrender all or a portion of such Holder’s Securities for conversion, if a Fundamental Change of the type described in clause (1) or (3) in the definition thereof occurs. In such event, Holders may surrender Securities for conversion at any time beginning on the actual Effective Date of such Fundamental Change until and including the date which is seven Scheduled Trading Days after the actual effective date of such transaction or, if later, until the related Fundamental Change Purchase Date.

A Holder may convert a portion of the principal amount of Securities if the portion is $1,000 or a multiple of $1,000. The number of shares of Common Stock issuable or the combination of cash payable and the number of shares of Common Stock issuable, if any, upon conversion of a Security shall be determined as set forth in Section 12.01(d).

(b) Conversion During Specified Period Immediately Prior to Stated Maturity. Notwithstanding anything herein to the contrary, a Holder may surrender its Securities for conversion beginning on August 15, 2026, until the close of business on the second Business Day immediately preceding the Stated Maturity.

(i) In respect of a Definitive Security, a Holder must (A) complete and manually sign the conversion notice on the back of the Security, or a facsimile of such conversion notice; (B) deliver such conversion notice, which is irrevocable, and the Security to the

Conversion Agent; (C) to the extent any shares of Common Stock issuable upon conversion are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Conversion Agent; (D) if required pursuant to Section 12.01(h) below, pay all transfer or similar taxes; and (E) if required pursuant to Section 2.01(d) above, pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled.

(ii) In respect of a beneficial interest in a Global Security, a Beneficial Owner must comply with DTC’s procedures for converting a beneficial interest in a Global Security and, if required pursuant to Section 2.01(d) above, pay funds equal to interest payable on the next Interest Payment Date to which such Beneficial Owner is not entitled, and if required, taxes or duties, if any.

The date a Holder satisfies the foregoing requirements is the “Conversion Date” hereunder. The Conversion Agent shall, within one Business Day of the Conversion Date, provide notice of such Conversion Date to such other parties as directed by the Company.

If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable or the combination of the cash payable and number of shares of Common Stock issuable upon the conversion, if any, shall be based on the total principal amount of the Securities converted.

Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee or the Authenticating Agent shall authenticate and deliver to the Holder, a new Security in an authorized denomination equal in principal amount to the unconverted portion of the Security surrendered.

Delivery of shares of Common Stock will be accomplished by delivery to the Conversion Agent of certificates for the relevant number of shares of Common Stock, other than in the case of Holders of Global Securities in book-entry form with DTC, in which case shares of Common Stock shall be delivered in accordance with DTC customary practices.

(d) Settlement Upon Conversion. In the event that the Company receives a Holder’s notice of conversion upon satisfaction of one or more of the conditions to conversion described in this Section 12.01, the Company will notify the relevant Holders within two Scheduled Trading Days following the Conversion Date whether the Company will satisfy its obligation to convert the Securities through delivery of (x) shares of Common Stock pursuant to clause (ii) below or (y) a combination of cash and shares of Common Stock pursuant to clause (i) below; provided, however, the Company may not elect to satisfy such obligation pursuant to clause (ii) below (A) on or after November 15, 2013, (B) in connection with any conversions made pursuant to Section 12.01(a)(iii) or (C) if the Company has made the election to waive pursuant to Section 12.01(e).

(i) If the Company chooses or has to satisfy its obligation to convert the Securities (the “Conversion Obligation”) by a combination of cash and shares of Common Stock, upon conversion the Company will, except as provided in Section 12.01(f), deliver to converting Holders, in respect of each $1,000 principal amount of Securities being converted, a “Settlement Amount” equal to the sum of the Daily Settlement Amounts for each of the 25 VWAP Trading Days during the Observation Period for such Security.

“Daily Settlement Amount,” for each of the 25 VWAP Trading Days during the Observation Period, shall consist of:

(A) cash equal to the lesser of $40 and the Daily Conversion Value; and

(B) to the extent the Daily Conversion Value exceeds $40, a number of shares of the Common Stock equal to, (A) the difference between the Daily Conversion Value and $40, divided by (B) the Daily VWAP for such VWAP Trading Day.

“Daily Conversion Value” means, for each of the 25 consecutive VWAP Trading Days during the Observation Period, 4% of the product of (1) the applicable Conversion Rate and (2) the Daily VWAP of the Common Stock on such VWAP Trading Day.

“Daily VWAP” means, for each of the 25 consecutive VWAP Trading Days during the Observation Period, the per share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page “HOS UN <EQUITY> VAP <GO>“, or its equivalent successor page, in respect of the period from 9:30 a.m. to 4:00 p.m., New York City time, on such VWAP Trading Day, or if such volume-weighted average price is unavailable or if such page or its equivalent is unavailable, the (a) price of each trade in shares of Common Stock multiplied by the number of shares of Common Stock in each such trade (b) divided by the total number of shares of Common Stock traded, in each case during such VWAP Trading Day from 9:30 a.m. to 4:00 p.m., New York City time on the New York Stock Exchange or, if the Company’s Common Stock is not traded on the New York Stock Exchange, the principal U.S. national or regional securities exchange on which the Common Stock is listed, by a nationally recognized independent investment banking firm (which may be one of the Initial Purchasers or its Affiliates) retained for this purpose by the Company.

The Settlement Amount in respect of any Security converted pursuant to this clause (i) will be delivered to converting Holders as soon as practicable following the last day of the Observation Period for the Conversion Date for such Security.

(ii) If the Company elects to satisfy all of its Conversion Obligation in shares of Common Stock pursuant to this Section 12.01(d), upon conversion the Company will, except as provided in Section 12.01(f), deliver to any converting Holder a number of shares of Common Stock equal to (i) the aggregate principal amount of Securities being converted by such Holder divided by $1,000 multiplied by (ii) the applicable Conversion Rate.

The shares of Common Stock in respect of any Security converted (and cash in lieu of any fractional shares) pursuant to this clause (ii) will be delivered through the Conversion Agent or DTC as soon as practicable following the last day of the Observation Period for the Conversion Date for such Security.

(iii) With respect to a conversion of a Security pursuant hereto, at and after the close of business on the last Trading Day (the “Relevant Date”) of the Observation Period applicable to such conversion, the Person in whose name any certificate representing any shares of Common Stock issuable upon such conversion is registered shall be treated as a stockholder of record of the Company; provided, however, that if any such shares of Common Stock constitute Additional Shares, then the Relevant Date with respect to such shares that constitute Additional Shares shall instead be deemed to be the later of (i) the last Trading Day of the Observation Period applicable to such conversion and (ii) the Effective Date of the Fundamental Change resulting in the Additional Shares. On and after the Conversion Date with respect to a conversion of a Security pursuant hereto, all rights of the Holder of such Security shall terminate, other than the right to receive the consideration deliverable upon conversion of such Security as provided herein. A Holder of a Security is not entitled, as such, to any rights of a holder of Common Stock until, if such Holder converts such Security and is entitled pursuant hereto to receive shares of Common Stock in respect of such conversion, the close of business on the Relevant Date or respective Relevant Dates, as the case may be, with respect to such conversion.

(e) Conversion After Irrevocable Election to Waive Right to Settle Solely in Cash and Settle Solely in Shares of Common Stock. At any time on or before the 28^th Scheduled Trading Day prior to November 15, 2013, the Company may, irrevocably waive, in its sole discretion, without the consent of the Holders, by notice to the Trustee and the Holders, its right to satisfy the Conversion Obligation prior to November 15, 2013 solely in shares of Common Stock.

(f) Exchange in Lieu of Conversion. When a Holder surrenders Securities for conversion, the Company may direct the Conversion Agent to surrender such Securities to a financial institution designated by the Company (the “Designated Institution”) for exchange in lieu of conversion. In order to accept any Securities surrendered for conversion, the Designated Institution must agree to deliver, in exchange for such Securities, shares of Common Stock based upon the applicable Conversion Rate or a combination of cash and shares of Common Stock, if applicable, equal to the consideration due upon conversion, as determined under Section 12.01(d). By the close of business on the Scheduled Trading Day immediately preceding the start of the Observation Period, the Company will notify the Holder surrendering Securities for conversion that (i) it has directed the Designated Institution to make an exchange in lieu of conversion and (ii) whether the Designated Institution will deliver, upon exchange, shares of Common Stock based upon the applicable Conversion Rate or a combination of cash and shares of Common Stock, if applicable, equal to the consideration due upon conversion, as determined under Section 12.01(d). If the Designated Institution accepts any such Securities, it will deliver the appropriate number of shares of Common Stock or cash and shares of Common Stock, if applicable, as the case may be, to the Conversion Agent and the Conversion Agent will deliver those shares of Common Stock or cash and shares of Common Stock, if applicable, as the case may be, to the Holder. Any Securities exchanged by the Designated Institution will remain outstanding. If the Designated Institution agrees to accept any Securities for exchange but does not timely deliver the related consideration, or if such Designated Institution does not accept the Securities for exchange, the Company will, as promptly as practical thereafter convert the Securities into shares of Common Stock or cash and shares of Common Stock, if applicable, in accordance with the election made by the Company in the initial notice to the Holders surrendering the Securities and based on the Observation Period as determined under Section 12.01(d). The Company’s designation of a financial institution to which the Securities may be submitted for exchange does not require the institution to accept any Securities. The Company will not pay any consideration to, or otherwise enter into any agreement with, the Designated Institution for or with respect to such designation.

(g) Cash Payments in Lieu of Fractional Shares. The Company shall not issue a fractional share of Common Stock upon conversion of Securities. Instead the Company shall deliver cash for the current market value of the fractional share. The current market value of a fractional share shall be determined to the nearest 1/10,000th of a share by multiplying the Daily VWAP of a full share of Common Stock on the final Trading Day of the related Observation Period by the fractional amount and rounding the product to the nearest whole cent.

(h) Taxes on Conversion. If a Holder converts Securities, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of shares of Common Stock upon the conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver the certificates representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which shall be due because the shares are to be issued in a name other than the Holder’s name, but the Conversion Agent shall have no duty to determine if any such tax is due. Nothing herein shall preclude any withholding of tax required by law.

(i) Certain Covenants of the Company.

(i) 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 or shares of Common Stock held in treasury, a sufficient number of shares of Common Stock, free of preemptive rights, to permit the conversion of the Securities.

(ii) All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares or treasury shares, shall be duly and validly issued and fully paid and nonassessable and shall be free from preemptive rights and free of any lien or adverse claim.

(iii) The Company shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of shares of Common Stock upon the conversion of Securities, if any, and shall cause to have listed or quoted all such shares of Common Stock on each U.S. national securities exchange or over-the-counter or other domestic market on which the Common Stock is then listed or quoted.

(iv) Before taking any action which would cause an adjustment increasing the Conversion Rate to an amount that would cause the Conversion Price to be reduced below the then par value per share of the Common Stock, if any, of the shares of Common Stock issuable upon conversion of the Securities, the Company will take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate.

Section 12.02. Adjustments to Conversion Rate. The applicable Conversion Rate shall be adjusted by the Company as follows:

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


where,

CR₀	=	the Conversion Rate in effect immediately prior to the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be;

CR’	=	the new Conversion Rate in effect immediately after the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Ex-Dividend Date for such dividend or distribution, or the effective date of such share split or share combination, as the case may be; and

OS’	=	the number of shares of Common Stock outstanding immediately after such dividend or distribution, or the effective date of such share split or share combination, as the case may be.

Such adjustment shall become effective immediately after (i) the Ex-Dividend Date for such dividend or distribution or (ii) the date on which such split or combination becomes effective, as applicable. If any dividend or distribution of the type described in this Section 12.02(a) is declared but not so paid or made, the new Conversion Rate shall again be adjusted to the Conversion Rate that would then be in effect if such dividend or distribution had not been declared.

(b) If the Company distributes to all holders of its Common Stock any rights or warrants entitling them to purchase, for a period of not more than 45 days after the Ex-Dividend Date for the distribution, shares of Common Stock at a price per share less than the average of the Last Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution, the Conversion Rate will be adjusted based on the following formula:


where,

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

CR’	=	the new Conversion Rate in effect immediately after the Ex-Dividend Date for such distribution;

OS₀	=	the number of shares of Common Stock outstanding immediately prior to the Ex-Dividend Date for such distribution;

X	=	the total number of shares of Common Stock issuable pursuant to such rights or warrants; and

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

For purposes of this Section 12.02(b), in determining whether any rights or warrants entitle the Holders to subscribe for or purchase shares of Common Stock at less than the average of the applicable Last Reported Sale Prices, and in determining the aggregate exercise or conversion price payable for such shares of Common Stock, there shall be taken into account any consideration received by the Company for such rights or warrants and any amount payable on exercise or conversion thereof, with the value of such consideration, if other than cash, to be determined by the Board of Directors. If any right or warrant described in this Section 12.02(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 or warrant had not been so issued. Any adjustment made pursuant to this Section 12.02(b) shall become effective immediately after the Ex-Dividend Date for the applicable distribution.

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

(i) dividends or distributions referred to in clause (a) or (b) above;

(ii) dividends or distributions paid exclusively in cash; and

(iii) Spin-Offs to which the provisions set forth below in this clause (c) shall apply;

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


where,

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

CR’	=	the new Conversion Rate in effect immediately after the Ex-Dividend Date for such distribution;

SP₀	=	the average of the Last Reported Sale Prices of the Common Stock over the 10 consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

FMV	=	the average of the Fair Market Values (as determined by the Board of Directors) of the shares of Capital Stock, evidences of indebtedness, assets or property distributed with respect to each outstanding share of Common Stock over the 10 consecutive Trading-Day period ending on the Trading Day immediately preceding the Ex-Dividend Date for such distribution.

Such adjustment shall become effective immediately after the Ex-Dividend Date for the applicable distribution.

With respect to an adjustment pursuant to this clause (c) where there has been a payment of a dividend or other distribution on the Common Stock or shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit (a “Spin-Off”), the Conversion Rate in effect immediately before 5:00 p.m., New York City time, on the tenth Trading Day immediately following, and including, the effective date of the Spin-Off will be increased based on the following formula:


where,

CR₀	=	the Conversion Rate in effect immediately prior to the tenth Trading Day immediately following, and including, the effective date of the Spin-Off;


CR’	=	the new Conversion Rate in effect immediately after the tenth Trading Day immediately following, and including, the effective date of the Spin-Off;

FMV₀	=	the average of the Last Reported Sale Prices of the Capital Stock or similar equity interest distributed to holders of Common Stock applicable to one share of Common Stock over the first 10 consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off; and

MP₀	=	the average of the Last Reported Sale Prices of Common Stock over the first 10 consecutive Trading Day period immediately following, and including, the effective date of the Spin-Off.

Such adjustment shall occur immediately after the tenth Trading Day immediately following, and including, the effective date of the Spin-Off provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten Trading Days following the effective date of any Spin-Off, references within the portion of this clause (c) related to “Spin-Offs” to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the effective date of such Spin-Off and the relevant Conversion Date.

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

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


where,

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

CR’	=	the new Conversion Rate in effect immediately after the Ex-Dividend Date for such distribution;

SP₀	=	the Last Reported Sale Price of the Common Stock on the Trading Day immediately preceding the Ex-Dividend Date for such distribution; and

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

An adjustment to the Conversion Rate made pursuant to this clause (d) shall become effective immediately after the Ex-Dividend Date for the applicable dividend or distribution. If any dividend or distribution described in this clause (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.

(e) If the Company or any of its Subsidiaries makes a payment in respect of a tender 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 Last Reported Sale Price of the Common Stock on the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate will be increased based on the following formula:


where,

CR₀	=	the Conversion Rate in effect at the close of business on the last Trading Day of the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires;

CR’	=	the new Conversion Rate in effect immediately following the last Trading Day of the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires;

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

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

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

SP’	=	the average of the Last Reported Sale Prices of Common Stock over the 10 consecutive Trading Day period commencing on the Trading Day next succeeding the date such tender or exchange offer expires.

The adjustment to the Conversion Rate under this clause (e) shall become effective immediately following the tenth Trading Day next succeeding the date such tender or exchange offer expires; provided that, for purposes of determining the Conversion Rate, in respect of any conversion during the ten Trading Days following the date that any tender or exchange offer expires, references within this clause (e) to 10 Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed between the date such tender or exchange offer expires and the relevant Conversion Date. If the Company or one of its Subsidiaries is obligated to purchase Common Stock pursuant to any such tender or exchange offer but are permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, the new Conversion Rate shall be readjusted to be the Conversion Rate that would be in effect if such tender or exchange offer had not been made.

(f) Without limiting the foregoing provisions of this Section 12.02, no adjustment will be made thereunder, nor shall an adjustment be made to the ability of a Holder to convert, for any distribution described therein if the Holder will otherwise participate in the distribution without conversion of such Holder’s securities as if such Holder held a number of shares of Common Stock equal to the applicable Conversion Rate, multiplied by the principal amount (expressed in thousands) of notes held by such holder, without having to convert its Securities. Further, if the application of the foregoing formulas in this Section 12.02 would result in a decrease in the Conversion Rate, no adjustment to the Conversion Rate will be made (except on account of share combinations).

(g) No adjustment to the Conversion Rate will be made unless as specifically set forth in this Section 12.02 and Section 12.03. Further, in the event of an adjustment to the Conversion Rate pursuant to Section 12.02(d) or Section 12.02(e), in no event will the Conversion Rate exceed 50 shares of Common Stock per $1,000 principal amount of Securities. For the avoidance of doubt, this cap on the Conversion Rate will not apply to an adjustment to the Conversion Rate pursuant to Section 12.02(a), Section 12.02(b) and Section 12.02(c).

(h) Without limiting the foregoing, no adjustment to the Conversion Rate need be made:

(i) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on securities of the Company and the investment of additional optional amounts in shares of Common Stock under any plan;

(ii) upon the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future employee, director or consultant benefit plan or program or employee stock purchase plan of or assumed by the Company or any of its Subsidiaries;

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

(iv) for a change in the par value of the Common Stock;

(v) for any “make-whole” premium as described in Section 6.01(d);

(vi) for accrued and unpaid Interest (including any Additional Interest); or

(vii) upon the issuance of any shares of Common Stock pursuant to the warrants contemplated by the Offering Memorandum.

(i) No adjustment to the Conversion Rate will be required unless the adjustment would require an increase or decrease of at least 1% of the Conversion Rate. If the adjustment is not made because the adjustment does not change the Conversion Rate 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 1/1000th of a share, as the case may be. Notwithstanding the foregoing, if the Securities are called for redemption, all adjustments not previously made will be made on the applicable Redemption Date.

(j) 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 Officers’ 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 Officers’ 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 the Holder of each Security at such Holder’s last address appearing on the Securities Register provided for in Section 2.05 of this Indenture within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(k) For purposes of this Section 12.02, 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. If the Company pays any dividend or makes any distribution on, or issues any rights, options or warrants in respect of, shares of Common Stock held in treasury by the Company, the Company shall not issue, transfer or convey such shares of Common Stock in a manner that would have the effect of circumventing the provisions of this Section 12.02.

(l) Whenever any provision of this Article 12 requires a calculation of an average of Last Reported Sale Prices or Daily VWAP over a span of multiple days, the Company will make appropriate adjustments (determined in good faith by the Board of Directors) to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the event occurs, at any time during the period from which the average is to be calculated.

Section 12.03. Adjustment to Common Stock Delivered Upon Certain Fundamental Changes. (a) If a Holder elects to convert Securities pursuant to Section 12.01(a)(iv) above in connection with a corporate transaction described therein and the transaction (1) has an effective date occurring on or prior to November 15, 2013 and (2) constitutes a Fundamental Change, subject to Section 12.04 below, the Conversion Rate for such Securities shall be increased by an additional number of shares of Common Stock (the “Additional Shares”) as described below. Any conversion will be deemed to have occurred in connection with such Fundamental Change if such Securities are surrendered for conversion at a time when the Securities would be convertible in light of the expected or actual occurrence of a Fundamental Change and notwithstanding the fact that a Security may then be convertible because another condition to conversion also has been satisfied.

(b) The number of Additional Shares will be determined by reference to the table attached as Schedule A hereto, based on the actual effective date on which the Fundamental Change occurs or becomes effective (the “Effective Date”) and the Stock Price paid per share of Common Stock with respect to such Fundamental Change; provided that if the Stock Price is between two Stock Price amounts set forth in such table or the Effective Date is between two Effective Dates in the table, the number of Additional Shares will be determined by a straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Price amounts and the two dates, as applicable, based on a 365-day year; provided further that if the Stock Price is greater than $140.00 per share (subject to adjustment as set forth in clause (d) below) or less than $35.26 per share (subject to adjustment as set forth in clause (d) below), then no Additional Shares will be issued upon conversion. Notwithstanding the

foregoing, the Conversion Rate shall not exceed 28.3607 per $1,000 principal amount of Securities on account of adjustments pursuant to this Section 12.03, subject to adjustments set out in Section 12.02(a) through (e).

(c) If a Holder elects to convert the Security as described in this Section 12.03 prior to the Effective Date of any Fundamental Change, and the Fundamental Change does not occur, the Holder will not be entitled to Additional Shares in connection with such conversion.

(d) The Stock Prices set forth in the first row of the table in Schedule A hereto will be adjusted as of any date on which the Conversion Rate of the Securities is otherwise adjusted pursuant to Section 12.02. 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 such adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of Additional Shares set forth in such table will be adjusted in the same manner as the Conversion Rate as set forth in Section 12.02.

(e) Settlement of Securities tendered for conversion upon a Fundamental Change, as to which the Conversion Rate will be increased by Additional Shares pursuant to this Section 12.03 shall occur as follows:

(i) if the last day of the applicable Observation Period for such Securities is prior to the third Scheduled Trading Day immediately preceding the Effective Date, the Company shall deliver shares of Common Stock or the Settlement Amount (together, in each case, with cash in lieu of fractional shares), determined in accordance with Section 12.01(d) by delivering the number of shares of Common Stock or the amount of cash and shares of Common Stock, as the case may be, based on the applicable Conversion Rate then in effect without such Additional Shares, as promptly as practicable immediately following the last day of the applicable Observation Period; provided that such Settlement Amount and related Daily Conversion Values shall be based on the Conversion Rate without giving effect to the Additional Shares to be added thereto as set forth in this subsection. As soon as practicable following the Effective Date, the Company shall calculate the increase in such amount of cash and Reference Property deliverable in lieu of Common Stock, as if the applicable Conversion Rate had been increased by such number of Additional Shares during the related Observation Period (and based upon the same Daily VWAP for each Trading Day in such Observation Period). If such increased amount results in an increase to the amount of cash to be paid to Holders, the Company will pay such increase in cash, and if such increased Settlement Amount results in an increase to the number of shares of Common Stock, the Company will deliver such increase by

delivering Reference Property based on such increased number of shares of Common Stock. Any shares of Common SPtock to be delivered following the Effective Date shall be subject to Section 12.05 and shall be delivered in Reference Property.

(ii) If the last day of the applicable Observation Period for such Securities is on or after the third Scheduled Trading Day immediately preceding the Effective Date, the Company shall deliver the shares of Common Stock or the Settlement Amount (together, in each case, with cash in lieu of fractional shares) determined in accordance with Section 12.01(d) (such determination, for the avoidance of doubt, to include the number of Additional Shares to be added to the Conversion Rate as set forth in this subsection) on the later to occur of (x) the Effective Date and (y) as promptly as practicable following the last day of the Observation Period. Any shares of Common Stock to be delivered on or following the Effective Date shall be subject to Section 12.05 and shall be delivered in Reference Property.

In no event shall the Company pay any such increase to the Conversion Rate or to the Settlement Amount if the transaction causing the increase to the Conversion Rate pursuant to this subsection never becomes effective.

Section 12.04. Conversion After a Public Acquirer Change of Control. (a) In the event of a Public Acquirer Change of Control, the Company may, in lieu of increasing the Conversion Rate by Additional Shares pursuant to Section 12.03 above and in lieu of application of Section 12.05, elect to adjust the Conversion Rate and the related Conversion Obligation such that from and after the Effective Date of such Public Acquirer Change of Control, Holders shall be entitled to convert their Securities, subject to the conditions in Section 12.01(a), into cash and a number of shares of Public Acquirer Common Stock, if applicable, in accordance with Section 12.01. The adjusted Conversion Rate shall be the Conversion Rate in effect immediately before the Public Acquirer Change of Control by multiplying it by a fraction:

(i) the numerator of which will be the average of the Daily VWAP of the Common Stock for the five consecutive VWAP Trading Days prior to but excluding the Effective Date of such Public Acquirer Change of Control, and

(ii) the denominator of which will be the average of Daily VWAP of the Public Acquirer Common Stock for the five consecutive VWAP Trading Days commencing on the VWAP Trading Day next succeeding the Effective Date of such Public Acquirer Change of Control.

(b) In order to make the election pursuant to this Section 12.04, the Company and the issuer of the Public Acquirer Common Stock shall execute with the Trustee a supplemental indenture providing that each Security shall be convertible into Public Acquirer Common Stock and execute an amendment to the Registration Rights Agreement (to the extent any Registrable Securities (as defined therein) remain outstanding) to make the provisions thereof apply to the Public Acquirer Common Stock. Such supplemental indenture shall provide for provisions and adjustments which shall be as nearly equivalent as may be practicable to the provisions and adjustments provided for in this Article 12 as determined in good faith by the Board of Directors of the Company or such issuer (which shall be conclusive).

(c) At least 35 Scheduled Trading Days prior to the expected Effective Date of a Fundamental Change that is also a Public Acquirer Change of Control, the Company will provide a notice to all Holders, the Trustee and the Paying Agent stating whether the Company (i) elects to adjust the Conversion Rate and the related Conversion Obligation as set forth in this Section 12.04 or (ii) does not elect to so adjust the Conversion Rate and the related Conversion Obligation, in which case the Holders will have the right to convert Securities and, if applicable, receive Additional Shares as set forth in Section 12.03. In addition, upon a Public Acquirer Change of Control, in lieu of converting the Securities, the Holders can, subject to certain conditions, require the Company to repurchase all or a portion of the Securities pursuant to Section 11.02.

Section 12.05. Effect of Recapitalizations, Reclassifications, and Changes of Common Stock. (a) Except as otherwise provided in Section 12.04, if any of the following events occur: (i) any recapitalization, reclassification or change of the outstanding shares of Common Stock (other than a subdivision or combination to which Section 12.02(a) applies), (ii) any consolidation, merger, binding share exchange or combination of the Company with another Person, or (iii) any sale or conveyance to another Person of all or substantially all of the property and assets of the Company and its Subsidiaries, in each case as a result of which Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event or transaction, a “Reorganization Event”), then, following the effective time of the Reorganization Event, the right to receive shares of Common Stock upon conversion of Securities, if any, will be changed into a right to receive the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) (the “Reference Property”) that a Holder of a like number of shares of Common Stock immediately prior to such Reorganization Event would have been entitled to receive upon such Reorganization Event. If the Reorganization Event causes Common Stock to be converted into the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the Reference Property will be deemed to be the weighted average of the types and amounts of

consideration received by the holders of Common Stock that affirmatively make such an election. The Company will notify Holders of the weighted average as soon as practicable after such determination is made. Upon such Reorganization Event, the Company or any Successor Company will enter into a supplemental indenture consistent with the foregoing. Such supplemental indenture shall provide for provisions and adjustments which shall be as nearly equivalent as may be practicable to the provisions and adjustments provided for in this Article 12, Article 10 and Article 11 and the definition of Fundamental Change, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provisions apply to such other Person if different from the original issuer of the Securities.

(b) Following the effective time of any such Reorganization Event, settlement of Securities converted shall be in units of Reference Property or cash and units of Reference Property, if applicable, determined in accordance with Section 12.01(d)(i) and Section 12.01(d)(ii) above based on the Daily Conversion Value and Daily VWAP of such Reference Property. For the purposes of determining such Daily Conversion Value and Daily VWAP, (i) if the Reference Property includes securities for which the price can be determined in a manner contemplated by the definition of Daily VWAP, then the value of such securities shall be determined in accordance with the principles set forth in such definition, as determined in good faith by the Company (which determination shall be conclusive and binding); (ii) if the Reference Property includes other property (other than securities as to which clause (i) applies or cash), then the value of such property shall be the Fair Market Value of such property as determined by the Company’s Board of Directors in good faith; and (iii) if the Reference Property includes cash, then the value of such cash shall be the amount thereof.

(c) Any issuer of securities included in the Reference Property shall execute an amendment to the Registration Rights Agreement (to the extent any Registrable Securities (as defined therein) remain outstanding) to make the provisions thereof applicable to such securities included in the Applicable Consideration.

(d) The Company shall cause notice of the execution of any supplemental indenture required by this Section 12.05 to be mailed to each Holder, at its address appearing on the Securities Register provided for in Section 2.05 of this Indenture, within 20 calendar days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(e) The above provisions of this Section 12.05 shall similarly apply to successive Reorganization Events.

(f) If this Section 12.05 applies to any event or occurrence, Section 12.02 shall not apply in respect of such event or occurrence.

(g) The Company shall not become a party to any Reorganization Event unless its terms are consistent with the foregoing. None of the foregoing provisions shall affect the right of a Holder of Securities to convert the Securities as set forth in Section 12.01 prior to the effective time of such Reorganization Event.

Section 12.06. Responsibility of Trustee. The Trustee and any other Conversion Agent shall not at any time be under any duty or responsibility to the Company or any Holder of Securities to determine when the Securities become convertible, the Conversion Rate, or whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed in making the same. The Trustee and any other Conversion Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Security; and the Trustee and any other Conversion Agent make no representations with respect thereto. Neither the Trustee nor any Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver any cash or shares of Common Stock or stock certificates or other securities or property upon the surrender of any Security for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article 12. Without limiting the generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 12.05 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the conversion of their Securities after any Reorganization Event or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 8.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, an Officers’ Certificate with respect thereto.

Section 12.07. Stockholder Rights Plan. To the extent that the Company has a rights plan in effect upon conversion of the Securities into Common Stock, the Holder will receive upon conversion of the Securities in respect of which the Company has elected to deliver Common Stock, if applicable, the rights under the rights plan, unless prior to any conversion, the rights have separated from the Common Stock, in which case, and only in such case, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of Common Stock shares of the Company’s Capital Stock, evidences of indebtedness or assets as described in Section 12.02(c) above, subject to readjustment in the event of the expiration, termination or redemption of such

rights. In lieu of any such adjustment, the Company may amend such applicable stockholder rights agreement to provide that upon conversion of the Securities the Holders will receive, in addition to the Common Stock issuable upon such conversion, the rights which would have attached to such Common Stock if the rights had not become separated from the Common Stock under such applicable stockholder rights agreement.

Section 12.08. No Stockholder Rights. For the avoidance of doubt, Holders of Securities will not have any rights as holders of Common Stock (including voting rights and rights to receive any dividends or other distributions on the Common Stock) if and until the Securities are converted into shares of Common Stock.

Section 12.09. Witholding Taxes for Adjustments in Conversation Rate. If the Company pays withholding taxes on behalf of a Holder as a result of an adjustment to the Conversion Rate, the Company may, at its option, set off such payments against payments of cash and shares of Common Stock on the Securities.

ARTICLE 13

SUBSIDIARY GUARANTEES

Section 13.01. Guarantee. (a) Subject to this Article 13, each of the Guarantors hereby, jointly and severally, unconditionally guarantees (a “Subsidiary Guarantee”) to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities or the obligations of the Company hereunder or thereunder, that:

(i) the principal of, premium, if any, and interest on the Securities will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium and interest on the Securities, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full, 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 any of such other obligations, that 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.

Failing payment when due of any amount so guaranteed, for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their obligations hereunder are 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 the Securities with respect to any provisions hereof or thereof; 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. Each Guarantor hereby waives diligence, presentment, demand of 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, protest, notice and all demands whatsoever and covenant that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in the Securities and this Indenture.

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid either to the Trustee or such Holder, this Subsidiary Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 7 hereof for the purposes of this Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 7 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Subsidiary Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantee.

Section 13.02. Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of Securities, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor 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 to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 13, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance.

Section 13.03. Execution and Delivery of Subsidiary Guarantee. To evidence its Subsidiary Guarantee set forth in Section 13.01 hereof, each Guarantor hereby agrees that a notation of such Subsidiary 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 by the Trustee and that either this Indenture or a supplemental indenture substantially in the form attached as Exhibit C will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 13.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Subsidiary Guarantee.

If an Officer whose signature is on this Indenture or on the Subsidiary Guarantee no longer holds that office at the time the Trustee authenticates the Security on which a notation of Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless.

The delivery of any Security by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Guarantors.

In the event that any of the Company’s Subsidiaries (including a Foreign Subsidiary) that is not already a Guarantor guarantees any indebtedness of the Company or a Domestic Subsidiary after the date of this Indenture, the Company will cause such Subsidiary to comply with the provisions of Section 3.09 hereof and this Article 13, to the extent applicable.

Section 13.04. Guarantors May Not Consolidate, etc., Except on Certain Terms. No Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless (a) immediately after giving effect to such transaction, no Default or Event of Default exists, (b) in the case of such consolidation,

merger, sale or disposition by the Company, the conditions in Section 4.01 are satisfied, and, unless such Guarantor’s Subsidiary Guarantee is subject to release under Section 13.05, (c) the Person acquiring the assets in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor under this Indenture and its Subsidiary Guarantee pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, on the terms set forth herein or therein.

In case of any such consolidation, merger, sale or disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the notation of Subsidiary Guarantee endorsed upon the Securities and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notation of Subsidiary Guarantees to be endorsed upon all of the Securities issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof.

Section 13.05. Releases. Each Guarantor shall be released:

(a) in connection with any sale or other disposition of all or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or its Subsidiary, provided that any such release shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure any indebtedness of the Company or the indebtedness of any of the other Guarantors shall also terminate upon such release, sale or transfer;

(b) in connection with any sale of all the Capital Stock of the relevant Guarantor, in accordance with the provisions of this Indenture;

(d) upon satisfaction and discharge of this Indenture in accordance with Section 9.01.

At the Company’s request and expense, the Trustee shall promptly execute and deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers’ Certificate certifying as to the compliance with this Section 13.05. Any Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 13.05 will remain liable for the full amount of principal of, premium, if any, and interest on the Securities and for the other obligations of any Guarantor under this Indenture as provided in this Article 13.

		Authorized Signatory

TERMS OF SECURITIES

1.625% Convertible Senior Notes due 2026

The Company issued this Security under an Indenture dated as of November 13, 2006 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Indenture”), among the Company, the guarantors party thereto and the Trustee, to which reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders. Additional Securities may be issued under the Indenture in an unlimited aggregate principal amount subject to certain conditions specified in the Indenture.

1. Interest

Xxxxxxxx Offshore Services, Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate of 1.625% per annum until (but excluding) November 15, 2013, reducing to a rate of 1.375% per annum beginning on such date and thereafter.

The Company will pay interest semiannually on May 15 and November 15 of each year (each, an “Interest Payment Date”) commencing May 15, 2007. Interest on the Securities will accrue from the most recent date to which interest has been paid on the Securities or, if no interest has been paid, from November 13, 2006. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

By no later than 11:00 a.m. (New York City time) on the date on which any principal of, interest (including any Additional Interest) or premium, if any, on any Security is due and payable, the Company shall deposit with the Paying Agent money sufficient to pay such amount. The Company will pay principal, premium and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Securities represented by a Global Security (including principal, interest (including any Additional Interest) and premium, if any) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will pay principal of Definitive Securities at the office or agency designated by the Company for such purpose. Interest (including any Additional Interest), on Definitive Securities will be payable (i) to Holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the Holders of these Securities and (ii) to Holders having

A-2

an aggregate principal amount of more than $5,000,000, either by check mailed to each Holder or, upon application by a Holder to the Registrar not later than the relevant record date, by wire transfer in immediately available funds to that Holder’s account within the United States, which application shall remain in effect until the Holder notifies, in writing, the Registrar to the contrary.

3. Redemption

No sinking fund is provided for the Securities. Subject to certain conditions specified in the Indenture, the Securities will be redeemable, at the option of the Company, in whole at any time or in part from time to time, at any time (i) on and after November 15, 2011 but prior to November 15, 2013 if the Last Reported Sale Price of the Company’s Common Stock is greater than or equal to 135% of the Conversion Price then in effect for at least 20 Trading Days within a period of 30 consecutive Trading Days ending on the Trading Day prior to the date on which the notice of redemption is mailed, and (ii) at any time and from time to time on or after November 15, 2013, at a Redemption Price specified in the Indenture.

If the Company redeems the Securities as described above after November 15, 2011 and prior to November 15, 2013, the Company shall pay a “make-whole” premium in cash equal to the present value of all remaining scheduled payments of interest on the Securities to be redeemed to but excluding November 15, 2013. The present value of the remaining interest payments will be computed using a discount rate equal to the Treasury Yield. “Treasury Yield” means the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) that has become publicly available at least two (2) Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source for similar market data)) most nearly equal to the then remaining term to November 15, 2013; provided, however, that if the then remaining term to November 15, 2013 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Yield shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the then remaining term to November 15, 2013 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used. In the event that the Redemption Date occurs after a Regular Record Date for the payment of interest and on or prior to the related Interest Payment Date, the Redemption Price for any such Securities to be redeemed shall be 100% of the principal amount of such Securities, and accrued and unpaid interest (including any Additional Interest) shall be paid to the Holder on such Regular Record Date.

A-3

Purchase by the Company at the Option of the Holder; Purchase at the Option of the Holder Upon a Fundamental Change

(a) Subject to the terms and conditions of the Indenture, a Holder shall have the option to require the Company to purchase all or a portion of its Securities held by such Holder on each of November 15, 2013, November 15, 2016 and November 15, 2021 at a Purchase Price specified in the Indenture.

(b) If a Fundamental Change shall occur at any time, each Holder shall have the right, at such Holder’s option and subject to the terms and conditions of the Indenture, to require the Company to purchase all or a portion of its Securities at a Fundamental Change Purchase Price specified in the Indenture.

5. Conversion

Subject to the conditions and procedures set forth in the Indenture, and during the periods specified in the Indenture, a Holder may convert Securities, on or prior to the close of business on the second Business Day immediately preceding Stated Maturity.

The initial Conversion Rate is 20.6260 shares of Common Stock per $1,000 principal amount of Securities, subject to adjustment in certain events described in the Indenture. Upon conversion, the Company will either (i) deliver shares of Common Stock based on the Conversion Rate or (ii) pay cash and shares of Common Stock, if any, based on a Daily Conversion Value calculated on a proportionate basis for each day of the 25-day Observation Period, as set forth in the Indenture. The Company shall deliver cash in lieu of any fractional share of Common Stock.

A Holder may convert a portion of the Securities only if the principal amount of such portion is $1,000 or a multiple of $1,000. No payment or adjustment shall be made for dividends on the Common Stock except as provided in the Indenture.

6. Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of principal amount of $1,000 and multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of Securities (i) so selected for redemption or, if a portion of any Security is selected for redemption, the portion thereof selected for redemption; (ii) surrendered for conversion or, if a portion of any Security is surrendered for

A-4

conversion, the portion thereof surrendered for conversion; or (iii) in certificated form for a period of 15 days prior to mailing a notice of redemption under Article 6 of the Indenture.

7. Persons Deemed Owners

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

8. Unclaimed Money

If money for the payment of principal, premium, if any, or interest (including any Additional Interest) remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company, subject to applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

9. Amendment, Waiver

Subject to certain exceptions, the Indenture contains provisions permitting an amendment of the Indenture, the Subsidiary Guarantees or the Securities with the written consent of the Holders of at least a majority in principal amount of the then outstanding Securities and the waiver of any Event of Default (other than with respect to nonpayment or in respect of a provision that cannot be amended without the written consent of each Holder affected) or noncompliance with any provision with the written consent of the Holders of a majority in principal amount of the then outstanding Securities.

In addition, the Indenture permits an amendment of the Indenture, the Subsidiary Guarantees or the Securities without the consent of any Holder under certain circumstances specified in the Indenture.

10. Defaults and Remedies

Subject to the following paragraph, if an Event of Default specified in the Indenture occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities by notice to the Company to be due and payable immediately. In addition, certain specified Events of Default will cause the Securities to become immediately due and payable without further action by the Holders.

The sole remedy for an Event of Default relating to the Company’s failure to comply with the reporting obligations under Article 5 of the Indenture, and for any failure to comply with the requirements of Section 314(a)(1) of the TIA, will for the 365 days after the occurrence of such an Event of Default consist exclusively of the right to receive Additional Interest on the principal amount of the Securities at a rate equal to 0.50% per annum.

A-5

Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal, interest (including any Additional Interest) or premium, if any) if it determines that withholding notice is in their interest.

11. Trustee Dealings with the Company

Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if it were not Trustee.

12. No Recourse Against Others

An incorporator, director, officer, employee, Affiliate or stockholder of the Company or a Guarantor, solely by reason of this status, shall not have any liability for any obligations of the Company or any Guarantor under the Securities, the Indenture, the Subsidiary Guarantees or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Security, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Securities.

13. Authentication

This Security shall not be valid until an authorized signatory of the Trustee manually authenticates this Security.

14. Abbreviations

Customary abbreviations may be used in the name of a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of , 200 , among (the “Guaranteeing Subsidiary”), a subsidiary of Xxxxxxxx Offshore Services, Inc. (or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the Indenture referred to herein) and Xxxxx Fargo Bank, National Association, as trustee under the Indenture referred to below (the “Trustee”).

WITNESSETH

WHEREAS, the Company has heretofore executed and delivered to the Trustee an Indenture, dated as of November 13, 2006 (the “Indenture”), providing for the issuance of 1.625% Convertible Senior Notes due 2026 (the “Securities”);

WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Securities and the Indenture on the terms and conditions set forth herein (the “Subsidiary Guarantee”); and

WHEREAS, pursuant to Section 3.09 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Securities as follows:

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Subsidiary Guarantee and in the Indenture including but not limited to Article 13 thereof.

3. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, stockholder or agent of the Guaranteeing

Subsidiary (other than the Company or a Guarantor in its capacity as a stockholder of a Subsidiary), as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Securities, any Subsidiary Guarantees, the Indenture or this Supplemental 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. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy.

4. New York Law to Govern. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

5. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

6. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

7. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary and the Company.

IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly executed and attested, all as of the date first above written.
