After such initial issuance, Initial Notes that are Transfer Restricted Notes may be transferred to QIBs in reliance on Rule 144A or outside the United States pursuant to Regulation S or to the Issuer, in accordance with certain transfer restrictions. Initial Notes that are offered in reliance on Rule 144A shall be issued in the form of one or more permanent Global Notes substantially in the form set forth in Exhibit A and bear the Restricted Notes Legend (collectively, the “Rule 144A Global Note”), deposited with the Note Custodian, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. Initial Notes that are offered in offshore transactions in reliance on Regulation S shall be issued in the form of one or more permanent Global Notes substantially in the form set forth in Exhibit A and bear the Regulation S Legend (collectively, the “Regulation S Global Note”), deposited with the Note Custodian, duly executed by the Issuer and authenticated by the Trustee as hereinafter provided. To the extent CUSIP numbers are issued pursuant to Section 2.14, the Rule 144A Global Note and the Regulation S Global Note shall each be issued with separate CUSIP numbers. The aggregate principal amount of each Global Note may from time to time be increased or decreased by adjustments made on the records of the Note Custodian, at the direction of the Trustee. Transfers of Notes among QIBs and to or by purchasers pursuant to Regulation S shall be represented by appropriate increases and decreases to the respective amounts of the appropriate Global Notes, as more fully provided in Section 2.15.

The Issuer shall execute and the Trustee shall, in accordance with this Section 2.1 and Section 2.2, authenticate and deliver the Global Notes that (i) shall be registered in the name of the Depositary or the nominee of the Depositary and (ii) shall be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions or held by the Note Custodian for the Depositary.

SECTION 2.2. Execution and Authentication. An Officer shall sign the Notes for the Issuer by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

A Note shall not be valid until authenticated by the manual signature of a Responsible Officer of the Trustee. The signature of a Responsible Officer of the Trustee shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall, upon receipt of a written order of the Issuer signed by one Officer directing the Trustee to authenticate the Notes and certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with and receipt of an Opinion of Counsel, authenticate Notes for original issue in the aggregate principal amount stated in such written order.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent or agents. An authenticating agent has the same rights as an Agent to deal with Holders or the Issuer or an Affiliate of the Issuer.

SECTION 2.3. Registrar; Paying Agent. The Issuer shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and (ii) an office or agency where Notes may be presented for payment to a Paying Agent. The Registrar shall keep a register of the Notes and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional Paying Agents. The term “Registrar” includes any co-registrar, and the term “Paying Agent” includes any additional Paying Agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer and/or any Restricted Subsidiary may act as Paying Agent or Registrar.

The Issuer shall notify the Trustee in writing, and the Trustee shall notify the Holders, of the name and address of any Agent not a party to this Indenture. The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which shall incorporate the relevant provisions of the TIA that relate to such Agent. If the Issuer fails to appoint or maintain a Registrar or Paying Agent, or fails to give the foregoing notice, the Trustee shall act as such, and shall be entitled to appropriate compensation in accordance with Section 7.7.

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent, at its Corporate Trust Office and its address in the City and State of New York.

The Issuer initially appoints DTC to act as the Depositary with respect to the Global Notes.

SECTION 2.4. Paying Agent to Hold Money in Trust. The Issuer 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 the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or Additional Interest, if any, or interest on the Notes, and shall notify the Trustee of any Default by the Issuer in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay to the Trustee all money held by it in trust for the benefit of the Holders or the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it in trust for the benefit of the Holders or the Trustee to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or any of its Subsidiaries) shall have no further liability for such money. If the Issuer or any of its Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon the occurrence of any of the events specified in Section 6.1, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5. 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 all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the

Issuer shall furnish to the Trustee at least seven (7) 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 the Holders, including the aggregate principal amount of the Notes held by each Holder thereof, and the Issuer shall otherwise comply with TIA § 312(a).

(a) Each Global Note shall (i) be registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, (ii) be delivered by the Trustee to the Depositary or pursuant to the Depositary’s instructions or held by the Note Custodian for the Depositary and (iii) bear the Global Note legends as required by Section 2.6(e).

Members of, or Participants in, the Depositary shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Note Custodian, or under such Global Note, and the Depositary may be treated by the Issuer, and the Trustee or any Agent and any of their respective agents, as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, the Trustee or any Agent or their respective agents from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants, the operation of customary practices governing the exercise of the rights of an owner of a beneficial interest in any Global Note.

Neither the Trustee nor any Agent shall have any responsibility or obligation to any Holder that is a member of (or a Participant in) the Depositary or any other Person with respect to the accuracy of the records of the Depositary (or its nominee) or of any member or Participant thereof, with respect to any ownership interest in the Notes or with respect to the delivery of any notice (including any notice of redemption) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to the Notes. The Trustee and any Agent may rely (and shall be fully protected in relying) upon information furnished by the Depositary with respect to its members, Participants and any beneficial owners in the Notes.

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

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with Section 2.15 and the rules and procedures of the Depositary. In addition, certificated Notes shall be transferred to beneficial owners in exchange for their beneficial interests only if (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Notes or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in each case, a successor depositary is not appointed by the Issuer within 90 days of such notice, (ii) an Event of Default of which a Responsible Officer of the Trustee has actual notice has occurred and

is continuing and the Registrar has received a request from any Holder of a Global Note to issue such certificated Notes or (iii) the Issuer, in its sole discretion, notifies the Trustee that it elects to cause the issuance of certificated Notes.

(c) In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 2.6(b), such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Issuer shall execute, and the Trustee shall authenticate and deliver to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Note an equal aggregate principal amount of certificated Notes of authorized denominations.

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

(f) At such time as all beneficial interests in Global Notes have been exchanged for certificated Notes, redeemed, repurchased or cancelled, all Global Notes shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction.

(1) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and certificated Notes at the Registrar’s request.

(2) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any stamp or transfer tax or similar governmental charge payable in connection therewith (other than any such stamp or transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Section 2.6(h), Section 2.10, Section 3.6, Section 4.10, Section 4.13 or Section 9.5).

(3) All Global Notes and certificated Notes issued upon any registration of transfer or exchange of Global Notes or certificated Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes (or interests therein) or certificated Notes surrendered upon such registration of transfer or exchange.

(4) The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of 15 days before

the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

(5) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent, or the Issuer shall be affected by notice to the contrary.

(6) The Trustee shall authenticate Global Notes and certificated Notes in accordance with the provisions of Section 2.2. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any certificated Note in exchange for a Global Note.

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

(8) Neither the Trustee nor any Agent shall have any 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 Note (including any transfers between or among Participants or beneficial owners of interests in any Global Note) 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.

(h) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Issuer shall issue and, upon receipt of a written order of the Issuer in accordance with Section 2.2, the Trustee shall authenticate (i) one or more unrestricted Global Notes in an aggregate principal amount equal to the principal amount of the beneficial interests in the Global Notes accepted for exchange by the Issuer and (ii) unrestricted certificated Notes in an aggregate principal amount equal to the principal amount of the certificated Notes that are accepted for exchange in the Exchange Offer, all as set forth in the written instructions of the Issuer. Concurrently with the issuance of such Notes, the Trustee shall cause the aggregate principal amount of the Global Notes to be reduced in accordance with the beneficial interests tendered in the Exchange Offer, and the Trustee shall deliver to the Persons designated by the Issuer the unrestricted Global Notes or unrestricted certificated Notes, as the case may be, issued and authenticated in accordance with the preceding sentence in the principal amounts specified by the Issuer.

SECTION 2.7. Replacement Notes. If any mutilated Note is surrendered to the Trustee, or the Issuer and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, the Issuer shall issue and the Trustee, upon the written order of the Issuer signed by an Officer of the Issuer, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer, the Trustee and the Agents may charge for their expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuer and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

SECTION 2.8. Outstanding Notes. The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on any payment date, money sufficient to pay the amounts under the Notes payable on that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.9. Treasury Notes. In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of which a Responsible Officer of the Trustee has written notice as being so owned shall be so disregarded. Notwithstanding the foregoing, Notes that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity.

SECTION 2.10. Temporary Notes. Until certificated Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by one Officer of the Issuer. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by one Officer, authenticate certificated Notes in certificate form in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.11. Cancellation. The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Section 2.7, the Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of their disposal delivered to the Issuer upon its written request therefor.

SECTION 2.12. Defaulted Interest. If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least 15 days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.13. Computation of Interest. Interest and Additional Interest, if any, on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 2.14. CUSIP Number. The Issuer in issuing the Notes may use a “CUSIP” number, and if it does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee in writing of any change in any CUSIP number.

SECTION 2.15. Special Transfer Provisions. Each Note issued pursuant to an exemption from registration under the Securities Act (other than in reliance on Regulation S) will constitute a Transfer Restricted Note and be required to bear the Restricted Notes Legend until the date that is one year after the later of the date of original issue and the last date on which the Issuer or any affiliate (within the meaning of Rule 405 under the Securities Act) of the Issuer was the owner of such Notes (or any predecessor thereto), unless and until such Transfer Restricted Note is transferred or exchanged pursuant to an effective registration statement under the Securities Act.

(a) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note issued in reliance on Regulation S to a QIB:

(1) The Registrar shall register the transfer of a Note issued in reliance on Regulation S by a Holder to a QIB if such transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit C from the proposed transferor; provided that the letter required by this clause (b) shall only be required on or prior to the 40th day after the later of the commencement of the offering of such Note and the issue date of such Note (such period through and including such 40th day, the “Restricted Period”). The Issuer shall provide written notice to the Trustee of the date that constitutes the final day of the Restricted Period in respect of any Notes issued in reliance on Regulation S; provided, however, that no such notice shall be required with respect to any Initial Notes issued in reliance on Regulation S, and January 30, 2013 shall constitute the final day of the Restricted Period for such Initial Notes.

(2) If the proposed transferee is a Participant and the Note to be transferred consists of an interest in the Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph (i) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in the Regulation S Global Note to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of such Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in such Regulation S Global Note to be so transferred.

(b) Transfers Pursuant to Regulation S. The following provisions shall apply with respect to registration of any proposed transfer of a Transfer Restricted Note pursuant to Regulation S:

(1) The Registrar shall register any proposed transfer of a Transfer Restricted Note by a Holder pursuant to Regulation S upon receipt of (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a letter substantially in the form set forth in Exhibit D hereto from the proposed transferor.

(2) If the proposed transferee is a Participant and the Transfer Restricted Note to be transferred consists of an interest in the Rule 144A Global Note upon receipt by the Registrar of (x) the letter, if any, required by paragraph

(i) above and (y) instructions in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the Rule 144A Global Note to be transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Rule 144A Global Note in an amount equal to the principal amount of the beneficial interest in such Rule 144A Global Note to be transferred.

(c) In the event that a Global Note is exchanged for Notes in certificated, registered form pursuant to Section 2.6, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (a) and (b) of this Section 2.15 above (including the certification requirements intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Issuer and notified to the Trustee in writing.

(d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing the Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only Notes that bear the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(e) Regulation S Legend. Upon the transfer, exchange or replacement of Notes not bearing the Regulation S Legend, the Registrar shall deliver Notes that do not bear the Regulation S Legend. Upon the transfer, exchange or replacement of Notes bearing the Regulation S Legend, the Registrar shall deliver only Notes that bear the Regulation S Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(f) General. By its acceptance of any Note bearing the Restricted Notes Legend or the Regulation S Legend, as applicable, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend or the Regulation S Legend, as applicable, and agrees that it shall transfer such Note only as provided in this Indenture. A transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a certificated Note or a beneficial interest in another Global Note shall be subject to compliance with applicable law and the applicable procedures of the Depositary but is not subject to any procedure required by this Indenture.

In connection with any proposed transfer pursuant to Regulation S or pursuant to any other available exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A), the Issuer may require the delivery of an Opinion of Counsel, other certifications or other information satisfactory to the Issuer.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.15.

SECTION 2.16. Issuance of Additional Notes. The Issuer shall be entitled to issue Additional Notes, including Exchange Notes issued in exchange therefor, in an unlimited aggregate principal amount under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price, amount of interest payable on the first interest payment date applicable thereto, transfer restrictions, any registration rights agreement and additional interest with respect thereto; provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9. The Initial Notes and any Additional Notes or Exchange Notes shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Issuer shall set forth in an Officers’ Certificate, a copy of which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(2) the issue price, the issue date, the CUSIP number of such Additional Notes, the first interest payment date and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue;

The Trustee shall, upon receipt of the Officers’ Certificate, authenticate the Additional Notes in accordance with the provisions of Section 2.2 of this Indenture.

SECTION 3.1. Notices to Trustee. If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7, it shall furnish to the Trustee, at least 30 days (or such shorter period as is acceptable to the Trustee) before a redemption date, an Officers’ Certificate setting forth the (i) section of this Indenture pursuant to which the redemption shall occur, (ii) redemption date and (iii) principal amount of Notes to be redeemed.

SECTION 3.2. Selection of Notes to Be Redeemed. If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or by such method as the Trustee, in its sole discretion, shall deem fair and appropriate (subject to the procedures of the Depositary and in a manner that complies with applicable legal requirements); provided,

however that no Notes of $2,000 in original principal amount or less shall be redeemed in part. In addition, if a partial redemption is made pursuant to Section 3.7(c), selection of the Notes or portions thereof for redemption shall be made by the Trustee only on a pro rata basis or on as nearly a pro rata basis as is practicable (subject to the procedures of the Depositary), unless that method is otherwise prohibited.

On and after the redemption date, interest will cease to accrue on Notes or portions of them called for redemption so long as the Issuer has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to this Indenture (including accrued and unpaid interest on the Notes to be redeemed). The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $1,000 or any integral multiples of $1,000 thereof) of the principal of the Notes that have denominations larger than $2,000.

SECTION 3.3. Notice of Redemption. The Issuer shall deliver or cause to be delivered in accordance with Section 11.2, a notice of redemption to each Holder whose Notes are to be redeemed (with a copy to the Trustee), at least 30 days but not more than 60 days before a redemption date (except that notices may be delivered more than 60 days before a redemption date if the notice is issued in accordance with Section 8.8).

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made, as appropriate);

(5) that Notes called for redemption must be surrendered to the Trustee to collect the redemption price;

(6) that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Issuer’s written request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall have delivered to the Trustee, at least 15 days prior to the date of the giving of the notice of redemption (or such shorter period as is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice mailed in the manner herein provided shall be deemed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note.

SECTION 3.4. Effect of Notice of Redemption. Except with respect to notices of redemption given in accordance with Section 3.7(c), once notice of redemption is delivered in accordance with Section 3.3, Notes called for redemption become due and payable on the redemption date at the applicable redemption price.

SECTION 3.5. Deposit of Redemption Price. On or before 11:00 a.m. (New York City time) on the redemption date, the Issuer shall deposit with the Trustee or with the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money sufficient to pay the redemption price on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of all Notes to be redeemed.

If Notes called for redemption or tendered in a Net Proceeds Offer or Change of Control Offer are paid or if the Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest and Additional Interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase date, interest and Additional Interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in a Net Proceeds Offer or Change of Control Offer (regardless of whether certificates for such securities are actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest and Additional Interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, interest and Additional Interest, if any, shall be paid on the unpaid principal from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest and Additional Interest, if any, not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1.

SECTION 3.6. Notes Redeemed in Part. Upon surrender and cancellation of a Note that is redeemed in part, the Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

(a) The Notes may be redeemed, in whole or in part, at any time prior to January 15, 2018 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium (calculated by the Issuer) as of, and accrued and unpaid interest and Additional Interest, if any, to, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date). The Issuer will calculate the Treasury Rate and Applicable Premium and prior to the redemption date file an Officers’ Certificate with the Trustee setting forth the Treasury Rate and Applicable Premium and showing the calculation of each in reasonable detail.

(b) The Notes are subject to redemption, at the option of the Issuer, in whole or in part, at any time or from time to time on or after January 15, 2018, at the redemption prices (expressed as percentages of the principal amount of Notes to be redeemed) set forth below, plus accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period beginning January 15 of the years indicated below:

(c) At any time or from time to time prior to January 15, 2016, the Issuer, at its option, may on any one or more occasions redeem up to 35.0% of the principal amount of the outstanding Notes issued under this Indenture (calculated after giving effect to any issuance of Additional Notes) with the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 105.125% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that:

(1) at least 65.0% of the aggregate principal amount of Notes issued under this Indenture on the Issue Date remains outstanding immediately after giving effect to any such redemption; and

(2) the redemption occurs not more than 180 days after the date of the closing of any such Qualified Equity Offering.

(a) The Issuer shall pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest shall be considered paid for all purposes hereunder on the date the Trustee or the Paying Agent (if other than the Issuer or a Subsidiary thereof) holds, as of 11:00 a.m. (New York City time) on the relevant payment date, U.S. dollars deposited by the Issuer in immediately available funds and designated for and sufficient to pay all such principal, premium, if any, and interest then due. The Issuer shall pay all Additional Interest, if any, in the same manner on the dates and amounts set forth in the Registration Rights Agreement.

(b) The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful.

(c) In the event the Issuer is required to pay Additional Interest pursuant to any Registration Rights Agreement, the Issuer will provide written notice to the Trustee of the Issuer’s obligation to pay Additional Interest no later than 15 days prior to the next interest payment date, which notice shall set forth the amount of Additional Interest to be paid by the Issuer. The Trustee shall not at any time be under any duty or responsibility to the Issuer, any Holders or any other Person to determine whether such Additional Interest is payable or the amount thereof.

SECTION 4.2. Maintenance of Office or Agency. The Issuer shall maintain an office or agency where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer and Guarantors in respect of the Notes and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Issuer may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Issuer hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Issuer in accordance with Section 2.3.

SECTION 4.3. Provision of Financial Information. Whether or not required by the SEC, so long as any Notes are outstanding, the Issuer will furnish to the Trustee and the Holders, or, to the extent permitted by the SEC, file electronically with the SEC through the SEC’s Electronic Data Gathering, Analysis and Retrieval System (or any successor system) within the time periods specified in the SEC’s rules and regulations:

(1) all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Issuer were required to file such reports; and

(2) all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer were required to file such reports.

If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, and such Unrestricted Subsidiaries, individually or taken together, would constitute a Significant Subsidiary, then the quarterly and annual financial information required by this Section 4.3 will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries.

For so long as any Notes remain outstanding, the Issuer shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

The Issuer will be deemed to have furnished such reports to the Trustee and the Holders if it has filed such reports with the SEC using the EDGAR filing system or if it has made such reports publicly available on its website. The furnishing of the above reports to the Trustee is for informational purposes only and the Trustee’s receipt of such reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants in this Indenture (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates) or any other agreement or document.

SECTION 4.4. Compliance Certificate. The Issuer shall deliver to the Trustee, within 90 days after the end of each fiscal year beginning with the fiscal year ending December 31, 2013, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that, to his or her knowledge, each entity has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto) and that, to his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest or Additional Interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer is taking or proposes to take with respect thereto.

The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 30 days after any Officer becomes aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

SECTION 4.5. Taxes. The Issuer shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency all material taxes, assessments and governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

SECTION 4.6. Stay, Extension and Usury Laws. The Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, make any Restricted Payment if at the time of such Restricted Payment:

(1) a Default shall have occurred and be continuing or shall occur as a consequence thereof;

(2) the Issuer is not able to incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or

(3) the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after June 1, 2011 (other than Restricted Payments made pursuant to clauses (2) through (12) of Section 4.7(b)), exceeds the sum (the “Restricted Payments Basket”) of (without duplication):

(A) 50.0% of Consolidated Net Income of the Issuer and the Restricted Subsidiaries for the period (taken as one accounting period) commencing on April 1, 2011 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100.0% of such deficit), plus

(B) 100.0% of (A) (i) the aggregate net cash proceeds and (ii) the Fair Market Value of (x) marketable securities (other than marketable securities of the Issuer), (y) Equity Interests of a Person (other than the Issuer or a Subsidiary of the Issuer) engaged in a Permitted Business and (z) other assets used in any Permitted Business, received by the Issuer or its Restricted Subsidiaries after June 1, 2011, in each case as a contribution to its common equity capital or from the issue or sale of Qualified Equity Interests or from the issue or sale of convertible or exchangeable Disqualified Equity Interests or convertible or exchangeable debt securities of the Issuer that have been converted into or exchanged for such Qualified Equity Interests (other than Equity Interests or debt securities sold to a Subsidiary of the Issuer or net cash proceeds received by the Issuer from Qualified Equity Offerings to the extent applied to redeem the Notes in accordance with the provisions set forth under Section 3.7(c)), and (B) the aggregate net cash proceeds, if any, received by the Issuer or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (A) above, plus

(C) 100.0% of the aggregate amount by which Indebtedness (other than Indebtedness held by a Subsidiary of the Issuer) of the Issuer or any Restricted Subsidiary is reduced on the Issuer’s consolidated balance sheet upon the conversion or exchange after June 1, 2011 of any such Indebtedness into or for Qualified Equity Interests, plus

(D) in the case of the disposition or repayment of or return on any Investment that was treated as a Restricted Payment made by the Issuer after June 1, 2011, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) 100.0% of the aggregate amount received by the Issuer or any Restricted Subsidiary in cash or other property (valued at the Fair Market Value thereof) as the return of capital with respect to such Investment and (ii) the amount of such Investment that was treated as a Restricted Payment, plus

(E) upon a Redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary immediately following such Redesignation, and (ii) the aggregate amount of the Issuer’s Investments in such Subsidiary to the extent such Investments reduced the Restricted Payments Basket and were not previously repaid or otherwise reduced.

(1) the payment of any dividend or redemption payment or the making of any distribution within 60 days after the date of declaration thereof if, on the date of declaration, the dividend, redemption or distribution payment, as the case may be, would have complied with the provisions of this Indenture;

(3) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Indebtedness of the Issuer or any Restricted Subsidiary in exchange for, or out of the proceeds of, the substantially concurrent incurrence of, Refinancing Indebtedness permitted to be incurred under Section 4.9 and the other terms of this Indenture;

(4) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Indebtedness of the Issuer or any Restricted Subsidiary (A) at a purchase price not greater than 101.0% of the principal amount of such Subordinated Indebtedness in the event of a Change of Control in accordance with provisions similar to Section 4.13 or (B) at a purchase price not greater than 100.0% of the principal amount thereof in accordance with provisions similar to Section 4.10; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Issuer has made the Change of Control Offer or Net Proceeds Offer, as applicable, as provided in such covenant with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Net Proceeds Offer;

(5) the redemption, repurchase or other acquisition or retirement for value of Equity Interests of the Issuer held by officers, directors or employees or former officers, directors or employees (or their transferees, estates or beneficiaries under their estates), either (x) upon any such individual’s death, disability, retirement, severance or termination of employment or service or (y) pursuant to any equity subscription agreement, stock option agreement, stockholders’ agreement or similar agreement; provided, in any case, that the aggregate cash consideration paid for all such redemptions, repurchases or other acquisitions or retirements shall not exceed (A) $10.0 million during the 2011 calendar year or any subsequent calendar year (with unused amounts in any calendar year being carried forward to the next succeeding calendar year) plus (B) the amount of any net cash proceeds received by or contributed to the Issuer from the issuance and sale after June 1, 2011 of Qualified Equity Interests to its officers, directors or employees that have not been applied to the payment of Restricted Payments pursuant to this clause (5), plus (C) the net cash proceeds of any “key-man” life insurance policies that have not been applied to the payment of Restricted Payments pursuant to this clause (5); and provided further that cancellation of Indebtedness owing to the Issuer from members of management of the Issuer or any Restricted Subsidiary in connection with a repurchase of Equity Interests of the Issuer will not be deemed to constitute a Restricted Payment for purposes of this Section 4.7 or any other provision of this Indenture;

(6) (A) repurchases, redemptions or other acquisitions or retirements for value of Equity Interests of the Issuer deemed to occur upon the exercise of stock options, warrants, rights to acquire Equity Interests of the Issuer or other convertible securities to the extent such Equity Interests of the Issuer represent a portion of the exercise or exchange price thereof and (B) any repurchases, redemptions or other acquisitions or retirements for value of Equity Interests of the Issuer made in lieu of withholding taxes in connection with any exercise or exchange of stock options, warrants or other similar rights;

For the purposes of determining compliance with any U.S. dollar-denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar-equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such Restricted Payment was made.

SECTION 4.8. Limitation on Dividend and Other Restrictions Affecting Restricted Subsidiaries. The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(a) pay dividends or make any other distributions on or in respect of its Equity Interests to the Issuer or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Equity Interests);

(b) make loans or advances, or pay any Indebtedness or other obligation owed, to the Issuer or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Issuer or any Restricted Subsidiary to other Indebtedness or obligations incurred by the Issuer or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(c) transfer any of its property or assets to the Issuer or any other Restricted Subsidiary (it being understood that such transfers shall not include any type of transfer described in clause (a) or (b) above);

(1) encumbrances or restrictions existing under agreements existing on the Issue Date (including, without limitation, the Credit Agreement) as in effect on that date;

(2) encumbrances or restrictions existing under this Indenture, the Notes and the Guarantees;

(3) any instrument governing Acquired Indebtedness or Equity Interests of a Person acquired by the Issuer or any of its Restricted Subsidiaries, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(4) any agreement or other instrument of a Person acquired by the Issuer or any of its Restricted Subsidiaries in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired (including after acquired property);

(5) any amendment, restatement, modification, renewal, supplement, refunding, replacement or refinancing of an agreement referred to in clauses (1), (2), (3), (4), (10) or this clause (5); provided, however, that such amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Issuer, not materially more restrictive than the encumbrances and restrictions contained in the agreements referred to in such clauses on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable;

(6) encumbrances or restrictions existing under or by reason of applicable law, regulation or order;

(10) any other agreement governing Indebtedness or other obligations entered into after the Issue Date if either (A) such agreement contains encumbrances and restrictions that in the good faith judgment of the Issuer are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date or (B) any such encumbrance or restriction contained in such Indebtedness is customary and does not prohibit (except upon a default or an event of default thereunder) the payment of dividends in an amount sufficient, as determined by the Issuer in good faith, to make scheduled payments of cash interest and principal on the Notes when due;

(11) customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements entered into in the ordinary course of business that restrict the disposition or distribution of ownership interests in or assets of such partnership, limited liability company, joint venture, corporation or similar Person;

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness); provided that the Issuer or any Restricted Subsidiary may incur additional Indebtedness (including Acquired Indebtedness), in each case, if, after giving effect thereto on a pro forma basis (including giving pro forma effect to the application of the proceeds thereof), the Issuer’s Consolidated Interest Coverage Ratio would be at least 2.00 to 1.00 (the “Coverage Ratio Exception”).

(b) Notwithstanding the above, each of the following incurrences of Indebtedness shall be permitted (the “Permitted Indebtedness”):

(1) Indebtedness under one or more Credit Facilities in an aggregate principal amount at any time outstanding, including the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal amount equal to the face amount thereof) not to exceed the greater of (A) $1.35 billion or (B) the sum of $750.0 million plus 25.0% of the Issuer’s Consolidated Tangible Assets determined at the time of incurrence;

(2) Indebtedness under (A) the Initial Notes issued on the Issue Date, (B) the Exchange Notes issued in exchange therefor pursuant to the Registration Rights Agreement, and (C) the Guarantees of the Notes;

(3) Indebtedness of the Issuer and its Restricted Subsidiaries to the extent outstanding on the Issue Date after giving effect to the use of proceeds of the Notes (other than Indebtedness referred to in clauses (1), (2), (4), (6), (7), (9), (10) and (12));

(4) guarantees by (A) the Issuer or Guarantors of Indebtedness permitted to be incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is being guaranteed is Subordinated Indebtedness, then the related Guarantee shall be subordinated in right of payment to the Notes or the Guarantee, as the case may be, and (B) Guarantees of Indebtedness incurred by Restricted Subsidiaries that are not Guarantors in accordance with the provisions of this Indenture;

(5) Indebtedness under Hedging Obligations entered into for bona fide hedging purposes of the Issuer or any Restricted Subsidiary in the ordinary course of business and not for the purpose of speculation; provided that in the case of Hedging Obligations relating to interest rates, (A) such Hedging Obligations relate to payment obligations on Indebtedness otherwise permitted to be incurred by this Section 4.9, and (B) the notional principal amount of such Hedging Obligations at the time incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate;

(B) if a Guarantor is the obligor on such Indebtedness and a Restricted Subsidiary that is not a Guarantor is the obligee, such Indebtedness is subordinated in right of payment to the Guarantee of such Guarantor; and

(ii) any sale or other transfer of any such Indebtedness to a Person other than the Issuer or any other Restricted Subsidiary shall be deemed, in each case of this clause (C), to constitute an incurrence of such Indebtedness not permitted by this clause (6);

or disposition of any business or assets of the Issuer or any Restricted Subsidiary or Equity Interests of a Restricted Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or Equity Interests for the purpose of financing or in contemplation of any such acquisition; provided that (A) any amount of such obligations included on the face of the balance sheet of the Issuer or any Restricted Subsidiary shall not be permitted under this clause (12) (contingent obligations referred to on the face of a balance sheet or in a footnote thereto and not otherwise quantified and reflected on the balance sheet will not be deemed “included on the face of the balance sheet” for purposes of the foregoing) and (B) in the case of a disposition, the maximum aggregate liability in respect of all such obligations outstanding under this clause (12) shall at no time exceed the gross proceeds actually received by the Issuer and the Restricted Subsidiaries in connection with such disposition;

(13) additional Indebtedness of the Issuer or any Restricted Subsidiary in an aggregate principal amount which, when taken together with the principal amount of all other Indebtedness incurred pursuant to this clause (13) and then outstanding, will not exceed the greater of (A) $150.0 million or (B) 7.0% of the Issuer’s Consolidated Tangible Assets determined at the time of incurrence;

(16) Indebtedness representing deferred compensation to directors, officers, members of management or employees (in their capacities as such) of the Issuer or any Restricted Subsidiary and incurred in the ordinary course of business.

For purposes of determining compliance with this Section 4.9, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (16) above or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer shall, in its sole discretion, classify such item of Indebtedness and

may divide and classify such Indebtedness in more than one of the types of Indebtedness described, except that Indebtedness incurred under the Credit Agreement on the Issue Date after giving effect to the application of the proceeds of the offering of the Initial Notes shall be deemed to have been incurred under clause (1) above, and may later reclassify any item of Indebtedness described in clauses (1) through (16) above (provided that at the time of reclassification it meets the criteria in such category or categories). In addition, for purposes of determining any particular amount of Indebtedness under this Section 4.9, (i) guarantees, Liens or letter of credit obligations supporting Indebtedness otherwise included in the determination of such particular amount shall not be included so long as incurred by a Person that could have incurred such Indebtedness; and (ii) the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

For the purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under this Section 4.9, the Issuer shall be in Default of this Section 4.9).

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale) of the shares and assets subject to such Asset Sale; and

(2) at least 75.0% of the total consideration from such Asset Sale and all other Asset Sales on a cumulative basis since the Issue Date received by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents.

For purposes of clause (2) above and for no other purpose, the following shall be deemed to be cash:

(A) the amount (without duplication) of any Indebtedness (other than Subordinated Indebtedness or intercompany Indebtedness) of the Issuer or such Restricted Subsidiary that is expressly assumed by the transferee of any such assets pursuant to a written agreement that releases the Issuer or such Restricted Subsidiary from further liability therefor,

(B) the amount of any securities, notes or other obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received),

(C) any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this Section 4.10(a)(2)(C) that is at that time outstanding, not to exceed the greater of (i) $75.0 million or (ii) 2.5% of the Issuer’s Consolidated Tangible Assets at the time of receipt of such Designated Non-cash Consideration, with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value, and

(D) the Fair Market Value of (i) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (ii) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or (iii) a combination of (i) and (ii).

If at any time any non-cash consideration received by the Issuer or any Restricted Subsidiary, as the case may be, in connection with any Asset Sale is repaid or converted into or sold or otherwise disposed of for cash (other than interest received with respect to any such non-cash consideration), then the date of such repayment, conversion or disposition shall be deemed to constitute the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall be applied in accordance with this Section 4.10.

Any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Permitted Lien or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure shall not be required to satisfy the conditions set forth in clauses (1) and (2) of Section 4.10(a).

Notwithstanding the foregoing, the 75.0% limitation referred to above shall be deemed satisfied with respect to any Asset Sale in which the cash or Cash Equivalents portion of the consideration received therefrom, determined in accordance with the foregoing provision on an after-tax basis, is equal to or greater than what the after-tax proceeds would have been had such Asset Sale complied with the aforementioned 75.0% limitation.

(b) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary may, no later than 365 days following the consummation thereof, apply all or any of the Net Available Proceeds therefrom to:

(1) repay, redeem or otherwise retire any Indebtedness of the Issuer or a Restricted Subsidiary (other than any Disqualified Equity Interests or Subordinated Indebtedness of the Issuer or a Guarantor, and other than Indebtedness owed to the Issuer or an Affiliate of the Issuer);

(2) (A) make any capital expenditure or otherwise invest all or any part of the Net Available Proceeds thereof in the purchase of assets (other than securities and excluding working capital or current assets for the avoidance of doubt) to be used by the Issuer or any Restricted Subsidiary in a Permitted Business, (B) acquire Qualified Equity Interests held by a Person other than the Issuer or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B).

The amount of Net Available Proceeds not applied or invested as provided in clauses (1) or (2) of this Section 4.10(b) shall constitute “Excess Proceeds.”

(c) On the 366th day after an Asset Sale (or, at the Issuer’s option, an earlier date), if the aggregate amount of Excess Proceeds equals or exceeds $50.0 million, the Issuer shall be required to make an offer to purchase or redeem (a “Net Proceeds Offer”) from all Holders and, to the extent required by the terms of other Pari Passu Indebtedness of the Issuer, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Issuer to make an offer to purchase or redeem such Pari Passu Indebtedness with the proceeds from any Asset Sale, to purchase or redeem the maximum principal amount of Notes and any such Pari Passu Indebtedness to which the Net Proceeds Offer applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100.0% of the principal amount of Notes and Pari Passu Indebtedness plus accrued and unpaid interest thereon, if any, to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Indebtedness, as applicable, in each case in denominations of $2,000 or integral multiples of $1,000 in excess thereof.

To the extent that the sum of the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds, or a portion thereof,

for any purposes not otherwise prohibited by the provisions of this Indenture. If the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes and Pari Passu Indebtedness. Upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

(d) The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Net Proceeds Offer Period”). No later than five (5) Business Days after the termination of the Net Proceeds Offer Period (the “Net Proceeds Purchase Date”), the Issuer will purchase the principal amount of Notes and Pari Passu Indebtedness required to be purchased pursuant to this Section 4.10 (the “Net Proceeds Offer Amount”) or, if less than the Net Proceeds Offer Amount has been so validly tendered, all Notes and Pari Passu Indebtedness validly tendered in response to the Net Proceeds Offer.

If the Net Proceeds Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Net Proceeds Offer.

Pending the final application of any Net Available Proceeds pursuant to this Section 4.10, the holder of such Net Available Proceeds may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Credit Facility or otherwise invest such Net Available Proceeds in any manner not prohibited by this Indenture.

On or before the Net Proceeds Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes and Pari Passu Indebtedness or portions of Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn, in each case in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Issuer or the Paying Agent, as the case may be, will promptly (but in any case not later than five (5) Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder and the Issuer will mail or deliver to each tendering holder or lender of Pari Passu Indebtedness, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Indebtedness so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Issuer, will authenticate and mail or deliver such new Note to such Holder, in a principal

amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. In addition, the Issuer will take any and all other actions required by the agreements governing the Pari Passu Indebtedness. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Net Proceeds Offer on the Net Proceeds Purchase Date.

Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, will be governed by Section 4.13 and/or Section 5.1 and not by this Section 4.10.

The Issuer shall comply with all applicable securities laws and regulations in the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”), unless:

(1) the terms of such Affiliate Transaction are not materially less favorable to the Issuer or such Restricted Subsidiary, as the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s length dealings with a Person who is not such an Affiliate or are otherwise fair to the Issuer or such Restricted Subsidiary from a financial point of view; and

(2) the Issuer delivers to the Trustee, with respect to any Affiliate Transaction involving aggregate value in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (1) above and a Secretary’s Certificate which sets forth and authenticates a resolution that has been adopted by the Independent Directors approving such Affiliate Transaction.

(1) transactions to the extent between or among (a) the Issuer and one or more Restricted Subsidiaries or (b) Restricted Subsidiaries;

(2) reasonable director, trustee, officer and employee compensation (including bonuses) and other benefits (including pursuant to any employment

agreement or any retirement, health, stock option or other benefit plan), payments or loans (or cancellation of loans) to employees of the Issuer and indemnification arrangements, in each case, as determined in good faith by the Issuer’s Board of Directors or senior management;

(3) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis or payable based on the allocation of tax liabilities under applicable tax laws;

(4) any Permitted Investments (other than pursuant to clause (1) of the definition thereof);

(6) any agreement in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not more disadvantageous to the Holders or the Issuer in any material respect than such agreement as it was in effect on the Issue Date;

(7) any transaction with a Person (other than an Unrestricted Subsidiary of the Issuer) which would constitute an Affiliate of the Issuer solely because the Issuer or a Restricted Subsidiary owns an equity interest in or otherwise controls such Person;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Issuer or the senior management of the Issuer, such transactions are on terms not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Issuer; and

(9) (a) any transaction with an Affiliate where the only consideration paid by the Issuer or any Restricted Subsidiary is Qualified Equity Interests or (b) the issuance or sale of any Qualified Equity Interests and the granting of registration and other customary rights in connection therewith.

SECTION 4.12. Limitation on Liens. The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, which Lien secures Indebtedness, unless contemporaneously with the incurrence of such Lien:

(1) in the case of any Lien securing Indebtedness that ranks pari passu with the Notes or a Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such Indebtedness with a Lien on the same collateral; and

(2) in the case of any Lien securing Indebtedness that is subordinated in right of payment to the Notes or a Guarantee, effective provision is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same collateral that is senior to the Lien securing such subordinated Indebtedness,

SECTION 4.13. Offer to Purchase upon Change of Control. Upon the occurrence of any Change of Control, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under Section 3.7, each Holder will have the right to require that the Issuer purchase all or any portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of purchase.

Not later than 30 days following any Change of Control, the Issuer will deliver, or cause to be delivered, to the Holders, with a copy to the Trustee, a notice:

(1) describing the transaction or transactions that constitute the Change of Control;

(2) offering to purchase, pursuant to the procedures required by this Indenture and described in the notice (a “Change of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “Change of Control Payment Date”), and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day preceding the Change of Control Payment Date; and

(3) describing the procedures, as determined by the Issuer, consistent with this Indenture, that Holders must follow to accept the Change of Control Offer.

On or before the Change of Control Payment Date, the Issuer will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered.

(1) accept for payment all Notes or portions of Notes (of $2,000 or integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer; and

(2) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

The Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Purchase Price for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes so tendered, if any; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business on such record date.

A Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by law. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The Issuer’s obligation to make a Change of Control Offer shall be satisfied if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer.

If Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price plus, to the extent not included in the Change of Control Purchase Price, accrued and unpaid interest, if any, to the date of redemption.

The Issuer shall comply with all applicable securities legislation in the United States, including, without limitation, the requirements of Rule 14e-l under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.13, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.13 by virtue of such compliance.

The provisions under this Indenture relating to the Issuer’s obligation to make a Change of Control Offer may be waived, modified or terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

SECTION 4.14. Corporate Existence. Subject to Article V, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of its Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Subsidiary and the rights (charter and statutory), licenses and franchises of the Issuer and its Subsidiaries; provided that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

SECTION 4.15. Conduct of Business. The Issuer shall engage, and shall cause its Restricted Subsidiaries to engage, only in businesses that, when considered together as a single enterprise, are primarily the Permitted Business.

SECTION 4.16. Additional Guarantees. If any Restricted Subsidiary of the Issuer, other than a Guarantor, shall guarantee any Indebtedness of the Issuer or any Guarantor under a Credit Facility, then the Issuer shall, within 30 days thereof, cause such Restricted Subsidiary to execute and deliver to the Trustee a supplemental indenture in substantially the form attached hereto as Exhibit B, pursuant to which such Restricted Subsidiary shall become a Guarantor with respect to the Notes, upon the terms and subject to the release provisions and other limitations set forth in Article X.

SECTION 4.17. Limitation on Designation of Unrestricted Subsidiaries. The Board of Directors of the Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) of the Issuer as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to Section 4.7, in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

(A) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the date of Designation, consist of Non-Recourse Debt, except for any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not recourse to the Issuer or any Restricted Subsidiary, and except for any guarantee of Indebtedness of such Subsidiary by the Issuer or a Restricted Subsidiary that is permitted as both an incurrence of Indebtedness and an Investment (in each case in amount equal to the amount of such Indebtedness so guaranteed) permitted under Section 4.7 and Section 4.9;

(B) on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than a guarantee permitted under clause (A) above) with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are not materially less favorable to the Issuer or the Restricted Subsidiary than those that could reasonably be expected to have been obtained at the time from Persons who are not Affiliates of the Issuer; and

(C) such Subsidiary is a Person with respect to which neither the Issuer nor any of its Restricted Subsidiaries has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results (in each case other than a guarantee permitted under clause (A) above).

Any such Designation by the Board of Directors of the Issuer shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such Designation and an Officers’ Certificate certifying that such Designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.9 or the Lien is not permitted under Section 4.12, the Issuer shall be in default of the applicable covenant.

The Board of Directors of the Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture.

Any such Redesignation shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such designation and an Officers’ Certificate certifying that such Redesignation complies with the foregoing conditions.

(a) Following the first date that the Notes have a Moody’s rating of Baa3 or higher or an S&P rating of BBB- or higher (each, an “Investment Grade Rating”) and no Default or Event of Default has occurred and is then continuing, then upon delivery by the Issuer to the Trustee of an Officers’ Certificate to the foregoing effect, the Issuer and the Restricted Subsidiaries will no longer be subject to the following covenants:

After the foregoing covenants have been terminated, the Issuer may not Designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.17.

(b) Neither the Trustee nor any Agent shall have any liability or responsibility with respect to, or obligation or duty to monitor, determine or inquire as to (i) the Issuer or any Guarantor’s compliance with any covenant under this Indenture (other than the covenant to make payment on the Notes) or (ii) as to whether or not Moody’s or S&P has adjusted the rating of the Notes.

(a) The Issuer will not, directly or indirectly, in a single transaction or a series of related transactions, consolidate or merge with or into another Person (whether or not the Issuer is the surviving Person), or sell, lease, transfer, convey or otherwise dispose of or assign all or substantially all of the assets of the Issuer and its Restricted Subsidiaries (taken as a whole) to any Person unless:

(B) the Person (if other than the Issuer) formed by or surviving or continuing from such consolidation or merger or to which such sale, lease, transfer, conveyance or other disposition or assignment shall be

made (collectively, the “Successor”) is a corporation, limited liability company or limited partnership organized and existing under the laws of the United States or of any State of the United States or the District of Columbia, and the Successor expressly assumes, by agreements in form and substance reasonably satisfactory to the Trustee, all of the obligations of the Issuer under the Notes and this Indenture; provided, that if the Successor is not a corporation, a Restricted Subsidiary that is a corporation expressly assumes as co-obligor all of the obligations of the Issuer under this Indenture and the Notes pursuant to a supplemental indenture to this Indenture executed and delivered to the Trustee;

(2) immediately after giving effect to such transaction and the assumption of the obligations as set forth in clause (1)(B) above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, no Default shall have occurred and be continuing;

(3) immediately after giving pro forma effect to such transaction and the assumption of the obligations as set forth in clause (1)(B) above and the incurrence of any Indebtedness to be incurred in connection therewith, and the use of any net proceeds therefrom on a pro forma basis, (i) the Issuer or its Successor, as the case may be, could incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception or (ii) the Consolidated Interest Coverage Ratio for the Issuer or its Successor, as the case may be, and its Restricted Subsidiaries would be greater than or equal to such Consolidated Interest Coverage Ratio prior to such transaction; and

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

For purposes of this Section 5.1, any Indebtedness of the Successor which was not Indebtedness of the Issuer immediately prior to the transaction shall be deemed to have been incurred in connection with such transaction.

(b) Except in circumstances under which this Indenture provides for the release of the Guarantee of a Guarantor as described under Section 10.5, no Guarantor will, and the Issuer will not permit any Guarantor to, directly or indirectly, in a single transaction or a series of related transactions, consolidate or merge with or into another Person (whether or not the Guarantor is the surviving Person) unless either:

(A) (i) such Guarantor will be the surviving or continuing Person; or (ii) the Person (if other than such Guarantor) formed by or surviving any such consolidation or merger is the Issuer or another

Guarantor or assumes, by agreements in form and substance reasonably satisfactory to the Trustee, all of the obligations of such Guarantor under the Guarantee of such Guarantor and this Indenture;

(B) immediately after giving effect to such transaction, no Default shall have occurred and be continuing; and

(C) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such merger or consolidation and such agreements and/or supplemental indenture (if any) comply with this Indenture; or

For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Restricted Subsidiaries of the Issuer, the Equity Interests of which constitute all or substantially all of the properties and assets of the Issuer, will be deemed to be the transfer of all or substantially all of the properties and assets of the Issuer.

(c) Upon any consolidation or merger of the Issuer or a Guarantor, or any transfer of all or substantially all of the assets of the Issuer in accordance with the foregoing, in which the Issuer or such Guarantor is not the continuing obligor under the Notes or its Guarantee, as applicable, the surviving entity formed by such consolidation or merger or into which the Issuer or such Guarantor is merged or the Person to which the sale, conveyance, lease, transfer, disposition or assignment is made will succeed to, and be substituted for, and may exercise every right and power of, the Issuer or such Guarantor under this Indenture, the Notes and the Guarantees with the same effect as if such surviving entity had been named therein as the Issuer or such Guarantor and, except in the case of a lease, the Issuer or such Guarantor, as the case may be, will be released from the obligation to pay the principal of and interest on the Notes or in respect of its Guarantee, as the case may be, and all of the Issuer’s or such Guarantor’s other obligations and covenants under the Notes, this Indenture and its Guarantee, if applicable.

(d) Notwithstanding the foregoing, (i) any Restricted Subsidiary may consolidate or merge with or into or convey, transfer or lease, in one transaction or a series of transactions, all or substantially all of its assets to the Issuer or another Restricted Subsidiary and (ii) the Issuer or any Guarantor may consolidate or merge with or into or convey, transfer or lease, in one transaction or a series of transactions, all or part of its properties and assets to the Issuer or another Guarantor or merge with a Restricted Subsidiary of the Issuer solely for the purpose of reincorporating the Issuer or Guarantor in a State of the United States or the District of Columbia, as long as the amount of Indebtedness of the Issuer or such Guarantor and its Restricted Subsidiaries is not increased thereby.

SECTION 6.1. Events of Default. Each of the following is an “Event of Default”:

(1) failure to pay interest on, or Additional Interest with respect to, any of the Notes when the same becomes due and payable and the continuance of any such failure for 30 days;

(2) failure to pay principal of or premium, if any, on any of the Notes when it becomes due and payable, whether at Stated Maturity, upon redemption, upon purchase, upon acceleration or otherwise;

(3) failure by the Issuer or any of its Restricted Subsidiaries to comply with any of their respective agreements or covenants described in Section 5.1, or failure by the Issuer to comply in respect of its obligations to make a Change of Control Offer pursuant to Section 4.13;

(4) (a) except with respect to Section 4.3, failure by the Issuer or any Restricted Subsidiary to comply with any other agreement or covenant in this Indenture and continuance of this failure for 60 days after notice of the failure has been given to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25.0% of the aggregate principal amount of the Notes then outstanding, or (b) failure by the Issuer for 120 days after notice of the failure has been given to the Issuer by the Trustee or to the Issuer and the Trustee by the Holders of at least 25.0% of the aggregate principal amount of the Notes then outstanding to comply with Section 4.3;

(5) default by the Issuer or any Restricted Subsidiary of the Issuer under any mortgage, indenture or other instrument or agreement under which there is issued or by which there is secured or evidenced Indebtedness for borrowed money by the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the Issue Date, which default:

(A) is caused by a failure to pay at its Stated Maturity principal on such Indebtedness within the applicable express grace period and any extensions thereof, or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity (which acceleration is not rescinded, annulled or otherwise cured within 30 days of receipt by the Issuer or such Restricted Subsidiary of notice of any such acceleration),

and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other Indebtedness with respect to which an event described in clause (A) or (B) has occurred and is continuing, aggregates $35.0 million or more;

(6) one or more judgments (to the extent not covered by insurance) for the payment of money in an aggregate amount in excess of $35.0 million shall be rendered

against the Issuer, any of its Significant Subsidiaries or any combination thereof and the same shall remain undischarged for a period of 60 consecutive days during which execution shall not be effectively stayed;

(7) the Issuer or any Significant Subsidiary of the Issuer or group of Restricted Subsidiaries of the Issuer that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

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

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

(i) is for relief against the Issuer or any Significant Subsidiary of the Issuer or group of Restricted Subsidiaries of the Issuer that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary, in an involuntary case;

(ii) appoints a custodian of the Issuer or any Significant Subsidiary of the Issuer or group of Restricted Subsidiaries of the Issuer that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary or for all or substantially all of the property of the Issuer or any of its Restricted Subsidiaries; or

(iii) orders the liquidation of the Issuer or any Significant Subsidiary of the Issuer or group of Restricted Subsidiaries of the Issuer that, taken together (as of the latest audited consolidated financial statements for the Issuer and its Restricted Subsidiaries), would constitute a Significant Subsidiary

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

(8) any Guarantee ceases to be in full force and effect (other than in accordance with the terms of such Guarantee and this Indenture) or is declared null and void and unenforceable or found to be invalid or any Guarantor denies its liability under the Guarantee of such Guarantor (other than by reason of release of such Guarantor from its Guarantee in accordance with the terms of this Indenture and the Guarantee).

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default specified in clause (7) of Section 6.1 with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately.

If an Event of Default specified in clause (7) of Section 6.1 occurs with respect to the Issuer, then all unpaid principal of, and premium, if any, and accrued and unpaid interest on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other action or notice on the part of the Trustee or any Holder of the Notes to the extent permitted by applicable law.

After such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the Notes then outstanding may rescind and annul such acceleration if:

(2) all existing Events of Default have been cured or waived other than nonpayment of accelerated principal and interest;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; and

(4) the Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

SECTION 6.3. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, interest and Additional Interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 6.4. Waiver of Past Defaults. Subject to Section 9.2, the Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium or Additional Interest on, or the principal of, the Notes.

SECTION 6.5. Control by Majority. The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust power conferred on it. However, (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction and (ii) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with any such direction received from the Holders.

SECTION 6.6. Limitation on Suits. A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(1) the Holder gives to the Trustee written notice of a continuing Event of Default or the Trustee receives such notice from the Issuer;

(2) the Holder or Holders of at least 25.0% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

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

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

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such use by a Holder prejudices the rights of any other Holders or obtains priority or preference over such other Holders).

SECTION 6.7. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium or Additional Interest, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, shall not be impaired or affected without the consent of the Holder.

SECTION 6.8. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.9. Trustee May File Proofs of Claim. The Trustee is authorized to 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 Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other securities or property payable or deliverable upon the conversion or exchange of the Notes or on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7. To the extent that the payment of any such compensation, expenses, disbursements and advances to the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.7 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing in this Section 6.9 shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money and property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.7, including payment of all reasonable compensation, expenses and liabilities incurred, and all advances made, by it and the costs and expenses of collection;

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

Third: without duplication, to the Holders for any other Obligations owing to the Holders under this Indenture and the Notes; and

Fourth: to the Issuer or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as the 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 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by Holders of more than 10.0% in principal amount of the then outstanding Notes.

(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

(1) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and, following the issuance of any Exchange Notes, the TIA, and the Trustee need perform only those duties that are specifically set forth in this Indenture and, following the issuance of any Exchange Notes, the TIA and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein); however, the Trustee shall examine the certificates and opinions furnished to it to determine whether or not they conform to the requirements of this Indenture.

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

(1) this paragraph does not limit the effect of paragraph (b) of this Section 7.1;

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

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5; and

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

(d) The Trustee shall not be liable for interest on or the investment of any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to this Section 7.1.

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any resolution, certificate, statement, instrument, opinion, notice, report, request, direction, consent, order, bond, debenture or other document (whether in original or facsimile form) 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 therein.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. Prior to taking, suffering or admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing, and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in conclusive reliance on the advice or opinion of such counsel.

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

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

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

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(h) 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, to the Agents and to each other agent, custodian and Person employed to act hereunder.

(i) The Trustee may request that the Issuer and each of the Guarantors shall deliver to the Trustee an Officers’ Certificate setting forth the names of individuals and/or titles of Officers of the Issuer and each Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture of the Issuer, the Notes and the Guarantees, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded.

(j) The Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or the Trustee shall have received from the Issuer or any other obligor upon the Notes or from any Holder written notice thereof at its address set forth in Section 11.2 and such notice references the Notes and this Indenture. In the absence of such actual knowledge or such notice, the Trustee may conclusively assume that no such Default or Event of Default exists.

(k) In no event shall the Trustee be responsible or liable for special, indirect, punitive, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

SECTION 7.3. Individual Rights of the Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the

Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA), it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as Trustee (if this Indenture has been qualified under the TIA) or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 and Section 7.11.

SECTION 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Guarantee, it shall not be accountable for the use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes, any Officers’ Certificate delivered to the Trustee hereunder, or any other document in connection with the sale of the Notes or pursuant to this Indenture other than the Trustee’s certificate of authentication hereunder.

SECTION 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall deliver to Holders a 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, premium, if any, or interest or Additional Interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

SECTION 7.6. Reports by Trustee to Holders of the Notes. Within 60 days after each January 15 beginning with January 15, 2013, and for so long as Notes remain outstanding, the Trustee shall transmit to the Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

A copy of each report at the time of its mailing to the Holders shall be mailed to the Issuer and filed with the SEC and each stock exchange, if any, on which the Issuer has informed the Trustee in writing the Notes are listed in accordance with TIA § 313(d). The Issuer shall promptly notify the Trustee in writing when the Notes are listed on any stock exchange and of any delisting thereof.

SECTION 7.7. Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee, as applicable, promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

Each of the Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.7 shall include its officers, directors, employees and agents) against any and all claims, damages, losses, liabilities, costs or expenses incurred by it (including, without limitation, the fees and expenses of its agents and counsel) arising out of or in connection with the acceptance or administration of its duties under this Indenture, the performance of its obligations and/or exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuer or any Guarantor (including this Section 7.7) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall be caused by its own negligence, bad faith or willful misconduct. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may have one separate counsel, and the Issuer shall pay the reasonable fees and expenses of such counsel for the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of the Issuer and the Guarantors under this Section 7.7 shall survive the satisfaction and discharge of this Indenture, the payment of the Notes or the resignation or removal of the Trustee.

To secure the Issuer’s payment obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture, the payment of the Notes and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

SECTION 7.8. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor trustee’s acceptance of appointment as provided in this Section 7.8.

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Issuer shall promptly appoint a successor trustee. Within one year after the successor trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor trustee to replace the successor trustee appointed by the Issuer.

If a successor trustee does not take office within 30 days after the retiring Trustee resigns or is removed, such retiring Trustee (at the expense of the Issuer), the Issuer or the Holders of at least 10.0% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor trustee.

If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.

A successor trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided that all sums owing to such Trustee hereunder have been paid and subject to the Lien provided for in Section 7.7. Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s and the Guarantors’ obligations under Section 7.7 shall continue for the benefit of the retiring Trustee.

SECTION 7.9. Successor Trustee by Merger, Etc. If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee or any Agent, as applicable.

SECTION 7.10. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. Such Trustee together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). Such Trustee is subject to TIA § 310(b) including the provision in § 310(b)(1) and (3); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or conflicts of interest or participation in other securities, of the Issuer or the Guarantors are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met.

SECTION 7.11. Preferential Collection of Claims Against the Issuer. The Trustee is subject to 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 therein.

SECTION 8.1. Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, by delivery of an Officers’ Certificate, at any time, elect to have either Section 8.2 or Section 8.3 applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

SECTION 8.2. Legal Defeasance. Upon the Issuer’s exercise under Section 8.1 of the option applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Obligations represented by the Notes and the Guarantees, which shall thereafter be deemed to be outstanding only for the purposes of Section 8.5 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other Obligations under such Notes, Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuer, shall execute instruments acknowledging the same), and this Indenture shall cease to be of further effect as to all such Notes and Guarantees, except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and interest and premium and Additional Interest, if any, on such Notes when such payments are due from the trust funds referred to in Section 8.4(1); (b) the Issuer’s obligations with respect to such Notes under Section 2.2, Section 2.3, Section 2.4, Section 2.6, Section 2.7, Section 2.10, and Section 4.2; (c) the rights, powers, trusts, duties and immunities of the Trustee, including without limitation thereunder, under Section 7.7, Section 8.5 and Section 8.7 and the obligations of the Issuer and the Guarantors in connection therewith; and (d) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3.

SECTION 8.3. Covenant Defeasance. Upon the Issuer’s exercise under Section 8.1 above of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 below, be released from its obligations under Section 4.3, Section 4.7, Section 4.8, Section 4.9, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.15, Section 4.16, Section 4.17 and Section 5.1(a)(3) on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not outstanding for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed outstanding for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any

term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.1, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.1 of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4, clauses (3) through (8) of Section 6.1 shall not constitute Events of Default.

SECTION 8.4. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either Section 8.2 or Section 8.3 to the outstanding Notes:

(1) the Issuer must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S. dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer and delivered to the Trustee, to pay the principal of and interest and Additional Interest, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that:

(A) the Issuer has received from, or there has been published by the United States Internal Revenue Service, a ruling, or

(B) since the date of this Indenture, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon, such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred,

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound,

(6) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others, and

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel to the effect that the conditions precedent provided for in clauses (1) through (6) of this Section 8.4 have been complied with.

SECTION 8.5. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6, all U.S. dollar and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Deposit Trustee”) pursuant to Section 8.4 or Section 8.8 in respect of the outstanding Notes shall be held in trust, shall not be invested, and shall be applied by the Deposit Trustee in accordance with the provisions of such Notes and this Indenture to the payment, either directly or through any Paying Agent (including the Issuer or any Subsidiary acting as Paying Agent) as the Deposit Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest and Additional Interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Deposit Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.4 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article VIII to the contrary notwithstanding, the Deposit Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any U.S. dollars or non-callable U.S. Government Obligations held by it as provided in Section 8.4 or Section 8.8 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Deposit Trustee (which may be the opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance or satisfaction and discharge, as the case may be.

SECTION 8.6. Repayment to Issuer. Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest or Additional Interest, if any, on any Note and remaining unclaimed for two years after such principal and premium, if any, or interest or Additional Interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be

discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

SECTION 8.7. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or U.S. Government Obligations in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer and the Guarantors under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, Section 8.3 or Section 8.8 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

SECTION 8.8. Discharge. This Indenture will be discharged and will cease to be of further effect (except as to rights of registration of transfer or exchange of Notes which shall survive until all Notes have been canceled and the rights, protections and immunities of the Trustee) as to all outstanding Notes when:

(1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust), have been delivered to the Trustee for cancellation; or

(2) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to Section 3.7 and, in any case, the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) to pay and discharge the entire Indebtedness (including all principal and accrued interest and Additional Interest, if any) on the Notes not theretofore delivered to the Trustee for cancellation;

(b) the Issuer has paid or caused to be paid all other sums payable by it under this Indenture; and

(c) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the date of redemption, as the case may be.

In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been complied with.

After the Notes are no longer outstanding, the Issuer’s and the Guarantors’ obligations in Section 7.7, Section 8.5 and Section 8.7 shall survive any discharge pursuant to this Section 8.8.

After such delivery or irrevocable deposit and receipt of the Officers’ Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

SECTION 9.1. Without Consent of Holders of the Notes. Notwithstanding Section 9.2, without the consent of any Holders, the Issuer, the Guarantors and the Trustee, at any time and from time to time, may amend or supplement this Indenture, the Guarantees or the Notes issued hereunder for any of the following purposes:

(2) to provide for uncertificated Notes in addition to or in place of certificated Notes;

(3) to provide for the assumption of the Issuer’s or a Guarantor’s obligations to the Holders in the case of a merger, consolidation or sale of all or substantially all of the Issuer’s or such Guarantor’s assets, or sale, lease, transfer, conveyance or other disposition or assignment in accordance with Section 5.1;

(4) to add any Guarantee or to effect the release of any Guarantor from any of its obligations under its Guarantee or the provisions of this Indenture (to the extent in accordance with this Indenture);

(5) to make any change that would provide any additional rights or benefits to the Holders or that does not materially adversely affect the rights of any Holder;

(7) to secure the Notes or any Guarantees or any other obligation under this Indenture;

(8) to evidence and provide for the acceptance of appointment by successor trustees;

(9) to conform the text of this Indenture or the Notes to any provision of the Description of the Notes contained in the Offering Memorandum, to the extent that such provision in the Description of the Notes was intended to be a substantially verbatim recitation of a provision of this Indenture, the Guarantees or the Notes, as evidenced by an Officers’ Certificate of the Issuer; or

(10) to provide for the issuance of Additional Notes or Exchange Notes in accordance with this Indenture and the Registration Rights Agreement, as the case may be.

After an amendment under this Indenture becomes effective, the Issuer shall deliver to Holders of the Notes a notice briefly describing such amendment. However, the failure to give such notice to all Holders, or any defect therein, will not impair or affect the validity of the amendment.

SECTION 9.2. With Consent of Holders of Notes. With the consent of the Holders of not less than a majority in aggregate principal amount of the Notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes), the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes or any Guarantees or, subject to Section 6.7, waive any existing Default or Event of Default or compliance with any provision of this Indenture or the Notes; provided, however, that no such amendment, supplement or waiver shall, without the consent of the Holder of each outstanding Note affected thereby (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Notes):

(3) reduce any premium payable upon redemption of the Notes or change the date on which any Notes are subject to redemption (other than the notice provisions) or waive any payment with respect to the redemption of the Notes; provided, however, that solely for the avoidance of doubt, and without any other implication, any purchase or repurchase of Notes (including pursuant to Section 4.10 and Section 4.13) shall not be deemed a redemption of the Notes;

(4) make any Note payable in money or currency other than that stated in the Notes;

(5) modify or change any provision of this Indenture or the related definitions to affect the ranking of the Notes or any Guarantee in a manner that adversely affects the Holders;

(6) reduce the percentage of Holders necessary to consent to an amendment or waiver to this Indenture or the Notes;

(7) waive a default in the payment of principal of or premium or interest or Additional Interest, if any, on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration);

(8) impair the rights of Holders to receive payments of principal of or interest or Additional Interest, if any, on the Notes on or after the due date therefor or to institute suit for the enforcement of any payment on the Notes;

(9) release any Guarantor from any of its obligations under its Guarantee or this Indenture, except as permitted by this Indenture; or

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

SECTION 9.3. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes or the Guarantees shall be set forth in an amended or supplemental indenture that complies with the TIA as then in effect.

SECTION 9.4. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder.

The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver.

SECTION 9.5. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.6. Trustee to Sign Amendments, Etc. The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In signing or

refusing to sign any amendment or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.1) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent thereto have been met or waived.

(a) Each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, that: (i) the principal of and premium, if any, and interest and Additional Interest, if any, on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest and Additional Interest, if any, to the extent lawful, and all other Obligations of the Issuer to the Holders or the Trustee under this Indenture or the Notes shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be 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. Each of the Guarantees shall be a guarantee of payment and not of collection.

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

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby agrees that, in the event of a Default in payment of principal or premium, if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are

prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under this Indenture.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture.

(e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

(f) Each Guarantor that makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed obligations under this Indenture to seek contribution from each other Guarantor in a pro rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with GAAP.

SECTION 10.2. Execution and Delivery of Guarantee. To evidence its Guarantee set forth in Section 10.1, each Guarantor agrees that this Indenture or a supplemental indenture in substantially the form attached hereto as Exhibit B shall be executed on behalf of such Guarantor by an Officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. Each Guarantor hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. In case the Officer, board member or director of such Guarantor whose signature is on this Indenture or supplemental indenture, as applicable, no longer holds office at the time the Trustee authenticates any Note, the Guarantee shall be valid nevertheless.

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

SECTION 10.3. Severability. In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 10.4. Limitation of Guarantors’ Liability. Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the 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 or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Guarantee (other than a company that is a direct or indirect parent of the Issuer) shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor (including, without limitation, any guarantees under the Credit Agreement) 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 its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference or fraudulent transfer or otherwise reviewable under applicable law.

SECTION 10.5. Releases. A Guarantor shall be released and relieved of any Obligations under its Guarantee, the Registration Rights Agreement and this Indenture upon:

(a) any sale, exchange or transfer (by merger, consolidation or otherwise) of the Equity Interests of such Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary, which sale, exchange or transfer does not violate the applicable provisions of this Indenture;

(b) the proper Designation of such Guarantor by the Issuer as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

(c) the release or discharge of all outstanding guarantees by the Guarantor of Indebtedness of the Issuer and its Restricted Subsidiaries under any Credit Facility;

(d) if the Issuer exercises its Legal Defeasance option or its Covenant Defeasance option pursuant to Section 8.2 or Section 8.3 or if its Obligations under this Indenture are discharged in accordance with Section 8.8; or

(e) dissolution of such Guarantor provided no Default or Event of Default has occurred that is continuing.

Upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the release of a Guarantor’s Guarantee set forth in this Indenture have been satisfied, the Trustee shall execute any documents reasonably requested by the Issuer in writing in order to evidence the release of any Guarantor from its obligations under its Guarantee.

Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X.

SECTION 10.6. Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

SECTION 11.1. Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA § 318(c), such imposed duties shall control.

SECTION 11.2. Notices. Any notice, request, direction, instruction or communication by the Issuer, any Guarantor or the Trustee to the others is duly given if in writing and delivered in person or mailed by first class mail (registered or certified, return receipt requested), telecopier or overnight air courier guaranteeing next day delivery, to the addresses set forth below:

The parties hereto, by written notice to the others, may designate additional or different addresses for subsequent notices or communications.

Any notice or communication shall also be so mailed to any Person described in TIA § 313(c), to the extent required by the TIA. Notwithstanding the foregoing, as long as the Notes are Global Notes, notices to be given to the Holders shall be given to the Depositary, in accordance with its applicable policies as in effect from time to time. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.

In respect of this Indenture, the Trustee shall not have any duty or obligation to verify or confirm that the Person sending instructions, directors, reports, notices or other communications or information by electronic transmission is, in fact, a Person authorized to give such instructions, directors, reports notices or other communications or information on behalf of the party purporting to send such electronic transmission; and the Trustee shall not have any liability for any losses, liability, costs or expenses incurred or sustained by any party as a result of such reliance upon or compliance with such instructions directors, reports, notices or other communications or information. Each other party, agrees to assume all risks arising out of the use of electronic methods to submit instructions, directions, reports, notices or other communications or indemnifications to the Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, notices, reports or other communications or information, and the risks of interception and misuse by third parties.

If a notice or communication is delivered in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it, except in the case of notices or communications given to the Trustee, which shall be effective only upon actual receipt.

If the Issuer delivers a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

SECTION 11.3. Communication by Holders of Notes with Other Holders of Notes. Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the Trustee, the Agents and anyone else shall have the protection of TIA § 312(c).

SECTION 11.4. Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Issuer to the Trustee to take any action under this Indenture (other than in connection with the issuance of the Initial Notes), the Issuer shall furnish to the Trustee upon request:

(a) an Officers’ Certificate (which shall include the statements set forth in Section 11.5) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

(b) an Opinion of Counsel (which shall include the statements set forth in Section 11.5) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been satisfied.

SECTION 11.5. Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA § 314(a)(4)) shall comply with the provisions of TIA § 314(e) and shall include substantially:

(d) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied.

SECTION 11.6. Rules by Trustee and Agents. The Trustee may make reasonable rules for action by or at a meeting of Holders. Each of the Agents may make reasonable rules and set reasonable requirements for its functions.

SECTION 11.7. No Personal Liability of Directors, Officers, Employees and Stockholders.

Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Guarantees.

SECTION 11.8. Governing Law; Consent to Jurisdiction. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE GUARANTEES. Each of the parties to this Indenture each hereby irrevocably submits to the non-exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan in The City of New York in any action or proceeding arising out of or relating to the Notes, the Guarantees or this Indenture, and all such parties hereby irrevocably agree that all claims in respect of such action or proceeding may be heard and determined in such New York State or federal court and hereby irrevocably waive, to the fullest extent that they may legally do so, the defense of an inconvenient forum to the maintenance of such action or proceeding.

SECTION 11.9. No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret any other indenture, loan or debt agreement of the Issuer or its Subsidiaries or of any other Person. Any such indenture, loan or debt agreement may not be used to interpret this Indenture.

SECTION 11.10. Successors. All agreements of the Issuer and the Guarantors in this Indenture and the Notes and the Guarantees, as applicable, shall bind their respective successors and assigns. All agreements of the Trustee in this Indenture shall bind its respective successors and assigns.

SECTION 11.11. Severability. In case any provision in this Indenture or in the Notes shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 11.12. Counterpart Originals. The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

SECTION 11.13. Table of Contents, Headings, Etc. The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing (or, with respect to Global Notes, otherwise in accordance with the rules and procedures of the Depositary); and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 11.14.

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

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

(e) If the Issuer shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a board resolution of the Issuer’s Board of Directors, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

SECTION 11.15. Force Majeure. In no event shall the Trustee or Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, fire, riots, strikes, or stoppages for any reason, embargoes, governmental actions, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the U.S. banking industry to resume performance as soon as practicable under the circumstances.

SECTION 11.16. Legal Holidays. If any payment date with respect to the Notes falls on a day that is not a Business Day, the payment to be made on such payment date will be made on the next succeeding Business Day with the same force and effect as if made on such payment date, and no additional interest will accrue solely as a result of such delayed payment.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) TO THE ISSUER OR ITS AGENT FOR REGISTRATION OR TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Note shall not be entitled to any benefits under the Indenture referred to on the reverse hereof or be valid or obligatory for any purpose.

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest. Oil States International, Inc., a Delaware corporation, and any successor thereto (the “Issuer”) promises to pay interest on the unpaid principal amount of this 5¹/₈% Senior Note due 2023 (a “Note”) at a fixed rate of 5.125% per annum. The Issuer will pay interest in U.S. dollars semiannually in arrears on January 15 and July 15, commencing on July 15, 2013 (each an “Interest Payment Date”) or if any such day is not a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, and no additional interest shall accrue solely as a result of such delayed payment. Interest on the Notes shall accrue from the most recent date to which interest has been paid, or, if no interest has been paid, from and including the date of issuance. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any (without regard to any applicable grace period), at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2) Method of Payment. The Issuer will pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders at the close of business on the January 1 and July 1 preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. If a Holder has given written wire transfer instructions to the Trustee at least 10 Business Days prior to the applicable Interest Payment Date, the Issuer will make all payments of principal, premium, interest and Additional Interest, if any, on such Holder’s Notes by wire transfer of immediately available funds to the account in New York specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Trustee or Paying Agent in the City and State of New York unless the Issuer elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of this Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The final principal amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. Payments in respect of Global Notes will be made by wire transfer of immediately available funds to the Depositary.

(4) Indenture. The Issuer issued the Notes under an Indenture, dated as of December 21, 2012 (the “Indenture”), among the Issuer, the Guarantors thereto and the Trustee. The terms of the Notes include those stated in the Indenture and those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. The Initial Notes issued on the Issue Date were initially issued in an aggregate principal amount of $400,000,000. The Indenture permits the issuance of Additional Notes subject to compliance with certain conditions.

The payment of principal, interest and Additional Interest, if any, on the Notes and all other amounts under the Indenture is unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Guarantors.

(b) The Notes are subject to redemption, at the option of the Issuer, in whole or in part, at any time or from time to time on or after January 15, 2018, at the redemption prices (expressed as percentages of the principal amount to be redeemed) set forth below, plus accrued and unpaid interest and Additional Interest thereon, if any, to the applicable redemption date (subject to the right of Holders on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the 12-month period beginning January 15 of the years indicated below:

Equity Offerings at a redemption price equal to 105.125% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Interest thereon, if any, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date); provided that:

(1) at least 65.0% of the aggregate principal amount of Notes issued under the Indenture on the Issue Date remains outstanding immediately after giving effect to any such redemption; and

(2) the redemption occurs not more than 180 days after the date of the closing of any such Qualified Equity Offering.

(d) The Notes may also be redeemed in certain circumstances set forth in Section 4.13 of the Indenture.

(6) Mandatory Redemption. Except as provided in the Indenture, the Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to Notes.

(a) Upon the occurrence of a Change of Control, the Issuer may be required to offer to repurchase all or any part of each Holder’s Notes pursuant to a Change of Control Offer on terms set forth in the Indenture.

(b) Upon the occurrence of certain Asset Sales, the Issuer may be required to offer to purchase Notes.

(c) Holders of the Notes that are the subject of an offer to purchase will receive notice of a Net Proceeds Offer or the Change of Control Offer, as applicable, pursuant to an Asset Sale or a Change of Control from the Issuer prior to any related purchase date and may elect to have such Notes purchased by completing the form titled “Option of Holder to Elect Purchase” attached hereto.

(8) Notice of Redemption. Notice of redemption shall be delivered at least 30 days but not more than 60 days before the redemption date (except that notices may be delivered more than 60 days before a redemption date if the notice is issued in accordance with Section 8.8 of the Indenture) to each Holder whose Notes are to be redeemed in accordance with Section 11.2 of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part so long as no partial redemption results in a Note having a principal amount of less than $2,000.

(9) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in initial denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of the Notes may be registered and the Notes may be exchanged as provided in the Indenture. The Registrar, the Trustee and the Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay any stamp or transfer tax or similar government charge required by law or permitted by the Indenture in accordance with Section 2.6(g)(2) of the Indenture. The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening

of 15 days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

(10) Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

(11) Amendment, Supplement and Waiver. The Indenture, the Notes and the Guarantees may be amended or supplemented as provided in the Indenture.

(12) Defaults and Remedies. If an Event of Default (other than an Event of Default relating to certain bankruptcy events with respect to the Issuer) shall have occurred and be continuing under the Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately. If an Event of Default relating to specified bankruptcy events occurs with respect to the Issuer, then all unpaid principal of, and premium, if any, and accrued and unpaid interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other action or notice on the part of the Trustee or any Holder of the Notes. Accelerations may be rescinded, and Events of Default may be waived as provided in the Indenture.

(13) No Recourse Against Others. No director, officer, employee, incorporator or stockholder, partner or member of the Issuer or any Guarantor, as such, will have any liability for any indebtedness, obligations or liabilities of the Issuer under the Notes or the Indenture or of any Guarantor under its Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Guarantees, to the extent permitted by applicable law.

(14) Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(15) 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 entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= custodian) and U/G/M/A (= Uniform Gifts to Minors Act).

(16) CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to the Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.
