SECTION 1.4. Certain Financial Tests and Calculations. Notwithstanding anything in this Indenture but subject to the immediately following paragraph, when calculating any applicable ratio or determining other compliance with this Indenture, including the determination of compliance with any provision of this Indenture in connection with a Specified Transaction undertaken in connection with the consummation of a Limited Condition Transaction, the date of determination of such ratio or other applicable covenant and determination of whether any Default or Event of Default has occurred, is continuing or would result therefrom or other applicable covenant shall, at the option of the Company (the Company’s election to exercise such option in connection with any Limited Condition Transaction, an “LCA Election”), be deemed to be the date that the definitive agreements for such Limited Condition Transaction are entered into (in each case, the “LCA Test Date”) and if, after such ratios and other provisions are measured on a Pro Forma Basis after giving effect to such Limited Condition Transaction and the other Specified Transactions to be entered into in connection therewith and the use of proceeds thereof as if they occurred at the beginning of the four consecutive fiscal quarter period being used to calculate such financial ratio ending prior to the LCA Test Date, the Company could have taken such action on the relevant LCA Test Date in compliance with such ratios and provisions, such provisions shall be deemed to have been complied with.

Notwithstanding anything to the contrary in this Indenture, with respect to any amounts Incurred or transactions entered into (or consummated) in reliance on a provision of this Indenture that does not require compliance with a financial ratio or test (any such amounts, the “Fixed Amounts”) substantially concurrently with any amounts Incurred or transactions entered into (or consummated) in reliance on a provision of this Indenture that requires compliance with any such financial ratio or test (any such amounts, the “Incurrence Based Amounts”), it is understood and agreed that the Fixed Amounts (and any cash proceeds thereof) shall be disregarded in the calculation of the financial ratio or test applicable to the Incurrence Based Amounts in connection with such substantially concurrent Incurrence, except that (i) Incurrences of Debt and Liens constituting Fixed Amounts shall be taken into account for purposes of the determination of Incurrence Based Amounts under Section 4.7, (ii) Incurrences of Debt constituting Fixed Amounts under clauses (w), (x) and (y) of Section 4.9(b)(1) shall be taken into account for purposes of the determination of Incurrence Based Amounts under Section 4.9(b)(1)(z) and (iii) Incurrences of Debt under Section 4.9(b)(1) shall be taken into account for purposes of the determination of Incurrence Based Amounts under clause (31) of the definition of Permitted Liens.

The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Note shall be dated the date of its authentication. The Notes will be issued in registered form, without coupons, and in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The registered Holder will be treated as the owner of such Note for all purposes. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture, and the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. (a) The Notes shall be issued initially in the form of one or more Global Notes, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Note Custodian, and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Each Global Note shall represent such of the outstanding Notes as shall be specified therein, and each shall provide that it shall represent the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges, redemptions and transfers of interests. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or the Note Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.6. (b) The Initial Notes are being issued by the Company only (i) to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act (“Rule 144A”)) (“QIBs”) and (ii) in reliance on Regulation S under the Securities Act (“Regulation S”). After such initial issuance, Initial Notes that are Transfer Restricted Notes may be transferred to QIBs in reliance on Rule 144A, outside the United States pursuant to Regulation S, to IAIs or to the Company, 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 Company and authenticated by the Trustee as hereinafter provided.

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, to or by purchasers pursuant to Regulation S and to or by IAIs 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. (c) Section 2.1(b) shall apply only to Global Notes deposited with or on behalf of the Depositary. The Company 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.

32 SECTION 2.2. Execution and Authentication. An Officer shall sign the Notes for the Company by manual, facsimile or PDF transmission 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 or electronic 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 Company signed by an Officer of the Company (an “Authentication Order”) directing the Trustee to authenticate the Notes and, except with respect to the Initial Notes, an Officer’s Certificate and Opinion of Counsel stating that all conditions precedent to the issuance of the Notes contained herein have been complied with, 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 Company 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 Company. SECTION 2.3. Registrar; Paying Agent. The Company 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 (“Paying Agent”). The Registrar shall keep a register of the Notes and of their transfer and exchange. The Company 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 Company may change any Paying Agent or Registrar without notice to any Holder. The Company and/or any Restricted Subsidiary may act as Paying Agent or Registrar. The Company 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 Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. If the Company 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 7.6. The Company initially appoints the Trustee to act as the Registrar and Paying Agent at the Corporate Trust Office of the Trustee. The Company 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 Company shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium or interest on the Notes, and shall notify the Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay to the Trustee all money held by it in trust for the benefit of the Holders or the Trustee. The Company 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 Company or any of its Subsidiaries) shall have no further liability for such money. If the Company 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. If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven (7) Business Days before each interest payment date

33 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.

Notwithstanding the foregoing, nothing herein shall prevent the Company, 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 Company that it is unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed by the Company within 90 days of such notice, (ii) the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by the Company within 90 days of such notice, (iii) an Event of Default of which a Responsible Officer of the Trustee has written 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 (iv) the Company, in its sole discretion, notifies the Trustee in writing 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 Company 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.

34 (e) Each Global Note shall bear the Global Note Legend on the face thereof. (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. (g) General Provisions Relating to Transfers and Exchanges. (1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Global Notes and certificated Notes upon receipt of an Authentication Order in accordance with Section 2.2 or at the Registrar’s request. (2) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company 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 2.7, Section 2.10, Section 3.6, Section 4.10, Section 4.13 or Section 9.4). (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 Company, 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 business 15 days before the day of any selection of Notes under Section 3.2 hereof 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.

(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 Company 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

35 examine the same to determine substantial compliance as to form with the express requirements hereof. (9) The transferor of any Note held in certificated form shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Internal Revenue Code of 1986, as amended. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information. SECTION 2.7. Replacement Notes. If any mutilated Note is surrendered to the Trustee, or the Registrar or the Company and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon receipt of an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company, the Trustee and the Agents may charge for their expenses in replacing a Note. Every replacement Note is an additional obligation of the Company 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 Company, the Subsidiary Guarantors or any of their respective Affiliates 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 principal amount of any Note is considered paid under Section 4.1 hereof, it ceases to be outstanding and interest on it ceases to accrue. If the Paying Agent (other than the Company, a Subsidiary of the Company, or an Affiliate of any thereof) holds, on the maturity date or date of redemption, money sufficient to pay all 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 Company, the Subsidiary Guarantors or by any of their respective Affiliates shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only 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 Company or an Affiliate of the Company 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 Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Company considers appropriate for temporary Notes. Without unreasonable delay, the Company shall prepare and the Trustee shall upon receipt of a written order of the Company 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.

36 SECTION 2.11. Cancellation. The Company at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Company 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 Sections 2.7 and 2.16, the Company 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. SECTION 2.12. Defaulted Interest. If the Company 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 Company 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 ten days before the special record date, the Company (or the Trustee, in the name and at the expense of the Company) 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. The Trustee will have no duty whatsoever to determine whether any defaulted interest is payable or the amount thereof. SECTION 2.13. Computation of Interest. Interest on the Notes shall be computed on the basis of a 360- day year comprised of twelve 30-day months. SECTION 2.14. CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers, and, if it does so, the Trustee shall use the CUSIP and/or ISIN 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 such numbers 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 Company shall promptly notify the Trustee in writing of any change in the CUSIP number and ISIN number. SECTION 2.15. Transfer and Exchange. (a) The following provisions shall apply with respect to any proposed transfer of a Rule 144A Note or an Institutional Accredited Investor Note prior to the date which is six months after (assuming at the time of transfer the Company is in compliance with the public information requirements of Rule 144(c) under the Securities Act and, if not, one year after) the later of the date of its original issue, the original issue date of any Additional Notes and the last date on which the Company or any Affiliate of the Company was the owner of such securities (or any predecessor thereto) (the “Resale Restriction Termination Date”): (1) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee, in the form of assignment as set forth on the reverse of the Note, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; (2) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to an IAI shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth under Exhibit D from the proposed transferee and, if requested by the Company or the Trustee, the delivery of an Opinion of Counsel, certification and/or other information satisfactory to each of them; and

37 (3) a transfer of a Rule 144A Note or an Institutional Accredited Investor Note or a beneficial interest therein to a non-U.S. person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth under Exhibit C from the proposed transferor and, if requested by the Company or the Trustee, the delivery of an Opinion of Counsel, certification and/or other information satisfactory to each of them. After the Resale Restriction Termination Date, interests in a Rule 144A Note or an Institutional Accredited Investor Note may be transferred in accordance with applicable law without requiring the certifications set forth under Exhibit C or Exhibit D or any additional certification. (b) The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the date which is forty days after the later of the Issue Date, the closing date of the issuance of any Additional Notes and when the Notes or any predecessor of the Notes are first offered to Persons other than distributors (as defined in Rule 902 of Regulation S) in reliance on Regulation S (the “Restricted Period”): (1) a transfer of a Regulation S Note or a beneficial interest therein to a QIB shall be made upon the representation of the transferee, in the form of assignment as set forth on the reverse of the Note, that it is purchasing the Note for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a QIB, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the exemption from registration provided by Rule 144A; (2) a transfer of a Regulation S Note or a beneficial interest therein to an IAI shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth under Exhibit D from the proposed transferee and, if requested by the Company or the Trustee, the delivery of an Opinion of Counsel, certification and/or other information satisfactory to each of them; and (3) a transfer of a Regulation S Note or a beneficial interest therein to a non-U.S. person shall be made upon receipt by the Trustee or its agent of a certificate substantially in the form set forth under Exhibit C hereof from the proposed transferor and, if requested by the Company or the Trustee, delivery of an Opinion of Counsel, certification and/or other information satisfactory to each of them. After the expiration of the Restricted Period, interests in the Regulation S Note may be transferred in accordance with applicable law without requiring the certifications set forth under Exhibit C or Exhibit D or any additional certification. (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 (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 Company 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 Company to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

38 (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 Company to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act. (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 Company may require the delivery of an Opinion of Counsel, other certifications or other information satisfactory to the Company. 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 Company shall be entitled to issue Additional Notes 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, first interest payment date applicable thereto, first date from which interest will accrue, 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 and provided further that if any Additional Notes are not fungible with the existing Notes for U.S. federal income tax purposes, as determined by the Company, such Additional Notes will have a separate CUSIP number and ISIN. The Initial Notes and any Additional Notes shall be treated as a single class for all purposes under this Indenture. With respect to any Additional Notes, the Company shall set forth in an Officer’s 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 and/or ISIN 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; (3) whether such Additional Notes shall be Transfer Restricted Notes; and (4) that such issuance is not prohibited by this Indenture. The Trustee shall, upon receipt of the Officer’s Certificate, authenticate the Additional Notes in accordance with the provisions of Section 2.2 of this Indenture. ARTICLE III REDEMPTION AND PREPAYMENT SECTION 3.1. Notices to Trustee. If the Company elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7, it shall furnish to the Trustee, at least three Business Days (or such shorter

39 period as is acceptable to the Trustee) before sending a notice of such redemption, an Officer’s Certificate setting forth (i) the paragraph of the Notes and/or section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date (which, in the case of a redemption subject to conditions, may be subject to extension until such conditions are satisfied), (iii) the principal amount of Notes to be redeemed and (iv) the redemption price or the method for determining the redemption price. SECTION 3.2. Selection of Notes to Be Redeemed. In the event that less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes (or portions of 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 then listed on any national securities exchange, by lot (except that any Notes represented by a Global Note will be selected in accordance with the applicable procedures and requirements of DTC); provided, however, that no Notes of $2,000 in original principal amount or less shall be redeemed in part. SECTION 3.3. Notice of Redemption. In connection with any redemption pursuant to Section 3.7, the Company shall mail or cause to be mailed (in each case sent by first class mail) in accordance with Section 11.1 and, in the case of Global Notes given in accordance with DTC procedures, a notice of redemption pursuant to this Section 3.3 to each Holder whose Notes are to be redeemed at its registered address (with a copy to the Trustee), at least ten days but not more than 60 days before the expected redemption date (except that notices may be delivered more than 60 days before a redemption date if the notice is issued in accordance with Article VIII). The notice shall identify the Notes to be redeemed (including the name of the Notes, the series, “CUSIP” numbers and corresponding “ISINs”, if applicable, interest rate, maturity date and, if known, certificate numbers) and shall state: (1) the redemption date (which, in the case of a redemption subject to conditions, may be subject to extension until such conditions are satisfied); (2) the redemption price (or the method by which it is to be determined); (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); (4) the name and address of the Paying Agent; (5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (6) that, unless the Company 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; (8) that no representation is made as to the correctness or accuracy of the CUSIP number and ISIN number, if any, listed in such notice or printed on the Notes; and (9) any conditions precedent to such redemption. At the Company’s written request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall have delivered to the Trustee, at least five Business Days prior to the date of the giving of the notice of redemption (or such shorter period as is acceptable to the Trustee), an Officer’s 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 sent in the manner herein provided shall be

40 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. Subject to the next paragraph, 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. Any redemption notice may, at the Company’s discretion, be subject to the satisfaction or waiver of one or more conditions precedent, including completion of a financing or other corporate transaction. In addition, if such redemption is subject to satisfaction or waiver of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the redemption date, or by the redemption date so delayed. The Company shall provide written notice of the satisfaction or waiver of such conditions, the delay of such redemption date or the rescission of such notice of redemption to the Trustee no later than the redemption date, and upon receipt the Trustee shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given. SECTION 3.5. Deposit of Redemption Price. On or before 11:00 a.m. (New York City time) on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent (if other than the Company or an Affiliate of the Company) money sufficient to pay the redemption price, together with accrued and unpaid interest, if any, to the applicable redemption date on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price and accrued and unpaid interest, if any, to the applicable redemption date on all Notes to be redeemed. If the Company has deposited with the Trustee or Paying Agent money sufficient to pay the redemption price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption (regardless of whether certificates for such securities are actually surrendered). If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest 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 Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption date until such principal is paid, and to the extent lawful on any interest 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 Company shall issue and, upon the written request of an Officer of the Company, the Trustee shall authenticate for the Holder at the expense of the Company 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. SECTION 3.7. Optional Redemption. (a) The Notes may be redeemed, in whole or in part, at any time or from time to time prior to June 1, 2026 at the option of the Company, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, but excluding, 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 Company will calculate the Treasury Rate and Applicable Premium and, prior to the redemption date, file an Officer’s Certificate with the Trustee setting forth the Treasury Rate and Applicable Premium and showing the calculation of each in reasonable detail.

41 (b) At any time or from time to time on or after June 1, 2026, the Company, at its option, may redeem the Notes in whole or in part, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest thereon, if any, to, but excluding, 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), if redeemed during the 12-month period beginning June 1 of the years indicated below: Year Redemption Price 2026…………………………………………………………... 102.125% 2027 …………………………………………………………... 101.417% 2028 …………………………………………………………... 100.708% 2029 and thereafter …………………………………………… 100.000% (c) Notwithstanding the foregoing, in connection with any tender offer for the Notes (including, but not limited to, a Change of Control Offer or Alternate Offer), if Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer and the Company, or any third party making such a tender offer in lieu of the Company, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company or such third party will have the right upon not less than ten nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to such tender offer, to redeem all Notes that remain outstanding following such purchase at a price equal to the price offered to each other Holder in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, to, but excluding, the redemption date. (d) Nothing herein shall limit the ability of the Company or its Affiliates to purchase or acquire Notes in open market purchases, tender or exchange offers or other negotiated transactions. ARTICLE IV COVENANTS SECTION 4.1. Payment of Notes. (a) The Company 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 Company or a Restricted Subsidiary thereof) holds, as of 11:00 a.m. (New York City time) on the relevant payment date, U.S. dollars deposited by the Company in immediately available funds and designated for and sufficient to pay all such principal, premium, if any, and interest then due. (b) The Company 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 (without regard to any applicable grace period), at the same rate to the extent lawful. SECTION 4.2. Maintenance of Office or Agency. The Company shall maintain an office or agency in the United States where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company and the Subsidiary Guarantors in respect of the Notes and this Indenture may be served. The Company 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 Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

42 The Company 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; provided that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in the United States for such purposes. The Company 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 Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.3. SECTION 4.3. Provision of Financial Information. (a) Whether or not the Company is subject to Section 13(a) or 15(d) of the Exchange Act, or any successor provision thereto, the Company shall provide to the Trustee and Holders the annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K which the Company would have been required to file with the SEC pursuant to such Section 13(a) or 15(d), or any successor provision thereto, if the Company were so required, such documents to be provided to the Trustee and Holders on or prior to the respective dates by which the Company would have been required to file such documents with the SEC if the Company were so required; provided that (A) any such reports and documents filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”) (or any successor system) or made publicly available on the Company’s website shall be deemed to have been delivered to the Trustee and the Holders of Notes for purposes of the foregoing requirements and (B) if the Company is no longer subject to Section 13(a) or 15(d) of the Exchange Act, or any successor provision thereto, then (x) no current reports on Form 8-K shall be required to be furnished if the Company determines in its good faith judgment that the applicable event requiring a current report on Form 8-K is not material to the Holders or the business, assets, operations, financial position or prospects of the Company and its Restricted Subsidiaries, taken as a whole; and (y) such annual, quarterly or current reports need not include any exhibits of Item 601 of Regulation S-K (except for financial statements of the Company) and shall not be required to comply with (i) Sections 302 and 404 of the Sarbanes-Oxley Act of 2002, and related Items 307 and 308 of Regulation S-K; (ii) Items 201, 402, 405, 406 and 407 of Regulation S-K; (iii) Section 13(e) of the Exchange Act (relating to the Iran Threat Reduction and Syrian Human Rights Act); (iv) Form SD (relating to conflict minerals); (v) Items 14 and 16 of Form 10-K or (v) Regulation G under the Exchange Act or Item 10(e) of Regulation S-K promulgated by the SEC with respect to any non-GAAP financial measures contained therein. (b) So long as any of the Notes remain outstanding, if at any time the Company is not subject to Section 13(a) or 15(d) under the Exchange Act, the Company will make available to any market making financial institution, securities analyst, prospective purchaser of Notes or beneficial owner of Notes, upon their request, the information required by Rule 144A(d)(4) under the Securities Act, until such time as the Holders of the Notes are able to sell all such Notes immediately without restriction pursuant to the provisions of Rule 144 under the Securities Act, or any successor provision thereto. (c) Within a reasonably prompt period of time after the date the annual or quarterly report for the prior fiscal period has been filed or furnished pursuant to this Section 4.3, the Company shall also hold live quarterly conference calls to discuss the Company’s financial condition and results of operations for the relevant reporting period (an “Earnings Call”). No fewer than three Business Days prior to the date such Earnings Call is to be held, the Company shall issue a press release to the appropriate U.S. wire services announcing such Earnings Call, which press release shall contain the time and the date of such Earnings Call and either include information on how to access such Earnings Call or direct the recipients thereof to contact an individual at the Company (for whom contact information shall be provided in such notice) to obtain information on how to access such Earnings Call. (d) In the event that any direct or indirect parent company of the Company becomes a guarantor of the Notes, the Company may satisfy its obligations under this Section 4.3 with respect to financial information relating to the Company by furnishing financial information relating to such parent company; provided that the same is accompanied by consolidating information that explains in reasonable

43 detail the differences between the information relating to such parent, on the one hand, and the information relating to the Company and its Subsidiaries on a standalone basis, on the other hand. (e) If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries and such Unrestricted Subsidiaries, either individually or collectively, would otherwise have been a Significant Subsidiary, then the annual and quarterly financial information required by this Section 4.3 shall include a reasonably detailed presentation, as determined in good faith by senior management of the Company, either on the face of the financial statements or in the footnotes to the financial statements or in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section, of the financial condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries. (f) Delivery of reports and documents to the Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s or any Subsidiary Guarantor’s, as the case may be, compliance with any of its covenants under this Indenture (as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate of the Company). The Trustee shall have no obligation or responsibility to determine whether the Company is required to file any report or other information with the SEC, whether the Company’s information is available on EDGAR (or any successor system) or whether the Company has otherwise delivered any notice or report in accordance with the requirements specified in this Section 4.3. SECTION 4.4. Compliance Certificate. The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year beginning with the fiscal year ending September 30, 2021, an Officer’s Certificate stating that a review of the activities of the Company and its Subsidiary Guarantors during the preceding fiscal year has been made under the supervision of the signing Officer 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 Company is taking or proposes to take with respect thereto). The Company 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 Officer’s Certificate specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto. SECTION 4.5. Reserved. SECTION 4.6. Stay, Extension and Usury Laws.

Excluded Contributions and the amount of net proceeds from any exchange for, conversion into or sale of Capital Stock of the Company pursuant to Section 4.7(b)(2) shall be excluded from the calculation of the amount available for Restricted Payments pursuant to Section 4.7(a)(4)(iii)(2).

(d) For purposes of this Section 4.7, if any Investment or Restricted Payment (or a portion thereof) would be permitted pursuant to one or more provisions described above and/or one or more of the clauses of the definition of Permitted Investments, the Company may divide and classify (but not later divide or reclassify) such Investment or Restricted Payment (or a portion thereof) in any manner that complies with this Section 4.7. Notwithstanding the foregoing, if the Company or any Restricted Subsidiary has made an Investment in another Person that is not a Restricted Subsidiary, and such Person later becomes a Restricted Subsidiary of the Company, then the Investment in such Person made prior to the time such Person became a Restricted Subsidiary shall be deemed to have been made pursuant to clause (1) of the definition of Permitted Investment.

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

48 (1) to pay dividends (in cash or otherwise) or make any other distributions in respect of its Capital Stock owned by the Company or any other Restricted Subsidiary or pay any Debt or other obligation owed to the Company or any other Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends, distributions or liquidating distributions prior to dividends, distributions or liquidating distributions being paid on Capital Stock shall not be deemed a restriction on the ability to make distributions on Capital Stock); (2) to make loans or advances to the Company or any other Restricted Subsidiary; or (3) otherwise to transfer any of its property or assets to the Company or any other Restricted Subsidiary. (b) Notwithstanding the restrictions in Section 4.8(a), the Company may, and may permit any Restricted Subsidiary to, suffer to exist any such encumbrance or restriction: (1) pursuant to any agreement in effect on the Issue Date (including the Senior Secured Credit Facilities); (2) pursuant to this Indenture, the Notes and the Note Guarantees; (3) pursuant to any agreement or Capital Stock of a Person that has been entered into, or issued, prior to the date on which such Person became a Restricted Subsidiary and not entered into, or issued, in connection with, or anticipation of, becoming a Restricted Subsidiary, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person so acquired; (4) in the case of a restriction described in Section 4.8(a)(3), contained in any security agreement securing Debt of a Restricted Subsidiary otherwise permitted under this Indenture, but only to the extent such restrictions restrict the transfer of the assets or property subject to such security agreement; (5) in the case of a restriction described in Section 4.8(a)(3), consisting of customary restrictions in leases, subleases, licenses or asset sale agreements and other similar contracts otherwise permitted under this Indenture so long as such restrictions relate only to the assets subject thereto; (6) any restrictions on cash or other deposits imposed by agreements entered into in the ordinary course of business; (7) customary provisions in shareholders agreements, joint venture agreements, organizational documents or similar binding agreements relating to any JV Entity or non-Wholly Owned Restricted Subsidiary and other similar agreements applicable to JV Entities and non- Wholly Owned Restricted Subsidiaries permitted under Section 4.7 and applicable solely to such JV Entity or non-Wholly Owned Restricted Subsidiary and the Capital Stock issued thereby; (8) in bona fide contracts for the sale of any property or assets, including customary restrictions with respect to a Subsidiary imposed pursuant to an agreement which has been entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Subsidiary; provided that such restriction terminates if such transaction is closed or abandoned; (9) customary net worth provisions contained in real property leases or contracts with customers or suppliers entered into by Restricted Subsidiaries of the Company; provided that the Company has determined in good faith that such net worth provisions could not reasonably be

49 expected to impair the ability of the Company and its Restricted Subsidiaries to meet their ongoing obligations; (10) restrictions or conditions upon the transfers of assets encumbered by a Lien permitted under Section 4.12, to the extent such restriction applies only to the property subject to such Lien; (11) any encumbrance or restriction contained in the terms of any Debt or Capital Stock otherwise permitted to be Incurred under this Indenture if the Company determines that any such encumbrance or restriction either (i) will not materially affect the Company’s ability to make principal or interest payments on the Notes and such restrictions are not materially less favorable to Holders of Notes than is customary in comparable financings or (ii) are not materially more restrictive, taken as a whole, 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 those contained in this Indenture or the Senior Secured Credit Facilities, in each case as determined in good faith by the Board of Directors or an Officer of the Company; (12) any encumbrance or restriction arising or agreed to in the ordinary course of business, not relating to any Debt or Capital Stock, and that, individually or in the aggregate, (x) do not detract from the value of the property or assets of the Company or any Restricted Subsidiary in any manner material to the Company or any Restricted Subsidiary or (y) do not materially impair the Company’s ability to make future principal, premium or interest payments on the Notes, in each case under this clause (12), as determined by the Company in good faith; (13) any encumbrances or restrictions of the type referred to in clauses (1), (2) and (3) of Section 4.8(a) imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (12) of this Section 4.8; provided that such encumbrances and restrictions contained in any such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing are, in the good faith judgment of the Company, not materially more restrictive, taken as a whole, than the encumbrances and restrictions prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing; or (14) if such encumbrance or restriction is the result of applicable laws or regulations. SECTION 4.9. Limitation on Debt. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, Incur any Debt except that the Company and any Subsidiary Guarantor may Incur Debt if, after giving Pro Forma Effect to the Incurrence of such Debt and the receipt and application of the proceeds thereof, the Consolidated Coverage Ratio of the Company would not be less than 2.00 to 1.00. (b) Notwithstanding Section 4.9(a), the following Debt may be Incurred (collectively, the “Permitted Debt”): (1) Debt of the Company or any Restricted Subsidiary under one or more Debt Facilities in an aggregate principal amount Incurred under this clause (1), including all Debt Incurred under Debt Facilities to refund or refinance any Debt Incurred pursuant to this clause (1), at any one time outstanding not to exceed (w) $400.0 million plus (x) the greater of (A) $500.0 million and (B) 100% of the Company’s Consolidated EBITDA for the Test Period, calculated on a Pro Forma Basis; plus (y) the greater of (A) $325.0 million and (B) the Borrowing Base; plus (z) an additional amount of Debt provided that, at the time of Incurrence and after giving effect to the Incurrence of such Debt and the application of the proceeds therefrom on such date, the Consolidated First Lien

50 Net Leverage Ratio of the Company would not exceed 3.75 to 1.00 (assuming for purposes of the calculation of the Consolidated First Lien Net Leverage Ratio under this clause (1), that any commitments with respect to Debt under any revolving Debt Facility (including the ABL Credit Facility) permitted to be Incurred under this clause (1) are fully drawn on such date); provided that solely for purposes of calculating the Consolidated First Lien Net Leverage Ratio under this clause (1), any outstanding Debt Incurred under this clause (1) that is unsecured shall nevertheless be deemed to be secured by a Lien on a first lien basis; (2) Debt of the Company or any Restricted Subsidiary outstanding on the Issue Date and not otherwise referred to in clauses (1) and (4) of this Section 4.9(b); (3) Debt owed by the Company to any Restricted Subsidiary or Debt owed by a Restricted Subsidiary to the Company or a Restricted Subsidiary; provided, however, that upon either the transfer or other disposition by such Restricted Subsidiary or the Company of any Debt so permitted to a Person other than the Company or another Restricted Subsidiary or the issuance (other than directors’ qualifying shares), sale, lease, transfer or other disposition of shares of Capital Stock (including by consolidation or merger) of such Restricted Subsidiary to a Person other than the Company or another Restricted Subsidiary such that it ceases to be a Restricted Subsidiary, the provisions of this clause (3) shall no longer be applicable to such Debt and such Debt shall be deemed to have been Incurred at the time of such transfer or other disposition; (4) Debt consisting of the Notes (other than any Additional Notes) and the Note Guarantees (other than in respect of any Additional Notes); (5) Guarantees by the Company or any Restricted Subsidiary of any Debt of the Company or a Restricted Subsidiary permitted to be Incurred under this Indenture; (6) Purchase Money Debt in an aggregate principal amount, including all Debt Incurred to refund or refinance any Debt Incurred pursuant to this clause (6), not to exceed, at any one time outstanding, the greater of (i) $60.0 million and (ii) 3.0% of the Company’s Consolidated Total Assets calculated on a Pro Forma Basis; (7) Debt in respect of Hedging Obligations Incurred not for speculative purposes; (8) Debt representing deferred compensation to employees of the Company and the Restricted Subsidiaries Incurred in the ordinary course of business; (9) Debt Incurred by the Company or any of the Restricted Subsidiaries in a Permitted Acquisition or any other Investment permitted under this Indenture or in any Asset Disposition, in each case to the extent constituting indemnification obligations or obligations in respect of purchase price (including earn-outs) or other similar adjustments; (10) Debt consisting of obligations of the Company or any of the Restricted Subsidiaries under deferred compensation or other similar arrangements incurred by such Person in connection with Permitted Acquisitions or any other Investment permitted under this Indenture; (11) Cash Management Obligations and other Debt in respect of netting services, automatic clearinghouse arrangements, overdraft protections and similar arrangements in each case incurred in the ordinary course of business; (12) Debt consisting of (a) the financing of insurance premiums or (b) take or pay obligations contained in supply arrangements, in each case, in the ordinary course of business;

(c) For purposes of determining compliance with, and the outstanding principal amount of any particular Debt Incurred pursuant to, and in compliance with, this Section 4.9:

52 (1) in the event that Debt meets the criteria of more than one of the types of Debt described in Section 4.9(a) and Section 4.9(b), the Company, in its sole discretion, may classify such item of Debt on the date of Incurrence (or later classify or reclassify such Debt, in its sole discretion) in any manner permitted by this covenant and shall only be required to include the amount and type of such Debt in one of such clauses; provided that any Debt outstanding under the Senior Secured Credit Facilities on the Issue Date shall at all times be treated as Incurred under clause (1) of the definition of Permitted Debt and may not be reclassified; (2) if obligations in respect of letters of credit are Incurred pursuant to a Debt Facility and relate to other Debt, then such letters of credit shall be treated as Incurred pursuant to clause (1) of the definition of Permitted Debt and such other Debt shall not be included; (3) except as provided in Section 4.9(c)(2), Guarantees of, or obligations in respect of letters of credit relating to, Debt which is otherwise included in the determination of a particular amount of Debt shall not be included in the determination of such amount of Debt, provided that the Incurrence of such Debt was in compliance with this covenant; (4) the principal amount of any Disqualified Capital Stock of the Company or a Restricted Subsidiary will be equal to the greater of the maximum redemption or repurchase price (not including, in either case, any redemption or repurchase premium) or the liquidation preference thereof; (5) Debt permitted by this covenant need not be permitted solely by reference to one provision permitting such Debt but may be permitted in part by one such provision and in part by one or more other provisions of this Section 4.9 permitting such Debt; (6) the amount of Debt 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; and (7) (i) if any Debt is Incurred to refinance Debt initially Incurred (or, Debt Incurred to refinance Debt initially Incurred) in reliance on any provision of this Section 4.9 measured by reference to a percentage of Consolidated EBITDA for the Test Period or Consolidated Total Assets, and such refinancing would cause the percentage of Consolidated EBITDA for the Test Period or Consolidated Total Assets restriction to be exceeded if calculated based on the Consolidated EBITDA for the Test Period or Consolidated Total Assets on the date of such refinancing, such percentage of Consolidated EBITDA for the Test Period or Consolidated Total Assets restriction shall not be deemed to be exceeded (and such newly Incurred Debt shall be deemed permitted) to the extent the principal amount of such newly Incurred Debt does not exceed the principal amount of such Debt refinanced, plus the Related Costs Incurred or payable in connection with such refinancing and (ii) if any Debt is Incurred to refinance Debt initially Incurred (or, Debt Incurred to refinance Debt initially Incurred) in reliance on any provision of this Section 4.9 measured by reference to a specified dollar amount restriction, and such refinancing would cause the specified dollar amount restriction to be exceeded, such specified dollar amount restriction shall not be deemed to be exceeded (and such newly Incurred Debt shall be deemed permitted) to the extent the principal amount of such newly Incurred Debt does not exceed the principal amount of such Debt refinanced, plus the Related Costs Incurred or payable in connection with such refinancing. (d) The accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Debt and the payment of dividends in the form of additional shares of Disqualified Capital Stock will not be deemed to be an Incurrence of Debt for purposes of this Section 4.9. (e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Debt, the U.S. dollar-equivalent principal amount of Debt denominated in a foreign

53 currency shall be calculated based on the relevant currency exchange rate in effect on the date such Debt was Incurred, in the case of term Debt, or first committed, in the case of revolving credit Debt; provided that if such Debt is Incurred to refinance other Debt 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 Debt does not exceed the principal amount of such Debt being refinanced, plus Related Costs incurred or payable in connection with such refinancing. Notwithstanding any other provision of this Section 4.9, the maximum amount of Debt that the Company may Incur pursuant to this Section 4.9 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. SECTION 4.10. Limitation on Asset Dispositions. (a) The Company shall not, and shall not permit any Restricted Subsidiary to, make any Asset Disposition unless: (1) the Company or the Restricted Subsidiary, as the case may be, receives consideration for such Asset Disposition at least equal to the Fair Market Value (measured as of the date of the definitive agreement with respect to such Asset Disposition) for the assets or Capital Stock sold or disposed of; and (2) at least 75% of the consideration for such Asset Disposition consists of: (i) cash or Cash Equivalents; (ii) the assumption of Debt of the Company or such Restricted Subsidiary (other than Subordinated Debt) and release, by all applicable creditors in writing, from all liability on the Debt assumed; (iii) the assumption by the purchaser of Debt (other than Subordinated Debt) of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Disposition; provided the Company and each Restricted Subsidiary are released from any Guarantee of payment of such Debt in connection with such Asset Disposition; (iv) Replacement Assets; (v) Designated Noncash Consideration; or (vi) any combination of the foregoing; provided that the amount of any securities or assets received by the Company or such Restricted Subsidiary that is converted into cash within 180 days of the closing of such Asset Disposition shall be deemed to be cash for purposes of this Section 4.10(a) (to the extent of the cash received). (b) Within 365 days after the receipt of any Net Available Proceeds from an Asset Disposition, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Available Proceeds at its option, in any combination of the following: (1) to repay, repurchase or otherwise retire (i) any Secured Debt of the Company or any Subsidiary Guarantor or (ii) any Debt of any Restricted Subsidiary of the Company that is not a Subsidiary Guarantor, in each case, other than Debt owed to the Company or an Affiliate of the Company;

54 (2) to repay, repurchase or otherwise retire any Debt of the Company or any Subsidiary Guarantor that is not Subordinated Debt, other than Debt owed to the Company or an Affiliate of the Company; provided that the Company shall (i) equally and ratably reduce obligations under the Notes, as provided in Section 3.7 or through open market purchases, private transactions or otherwise, in each case, at or above 100% of the principal amount thereof or (ii) make an offer (in accordance with the procedures set forth below for an Offer to Purchase) to all Holders to purchase their Notes on a ratable basis with such Debt at 100% of the principal amount thereof, in each case, plus the amount of accrued but unpaid interest on the Notes that are purchased or redeemed; (3) to acquire Replacement Assets or make capital expenditures; provided that, the Company or such Restricted Subsidiary will be deemed to have complied with its obligations under this Section 4.10(b) if it enters into a binding commitment to acquire Replacement Assets prior to 365 days after the receipt of the applicable Net Available Proceeds and such acquisition of Replacement Assets is consummated prior to 545 days after the date of receipt of the applicable Net Available Proceeds; provided, further, that upon any abandonment or termination of such commitment, the Net Available Proceeds not so applied shall constitute Excess Proceeds and be applied as set forth in Section 4.10(c); or (4) any combination of the foregoing. (c) Any Net Available Proceeds that are not applied or invested as provided in Section 4.10(b) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, or earlier, at the Company’s election, the Company will apply the Excess Proceeds to the repayment of the Notes and any other Pari Passu Debt outstanding with similar provisions requiring the Company to make an Offer to Purchase such Debt with the proceeds from any Asset Disposition as follows: (1) the Company will make an Offer to Purchase from all Holders of the Notes in accordance with the procedures set forth in this Indenture in the maximum principal amount (expressed in amounts of $2,000 or integral multiples of $1,000 in excess thereof) of Notes that may be purchased out of an amount (the “Note Amount”) equal to the product of such Excess Proceeds multiplied by a fraction, the numerator of which is the outstanding principal amount of the Notes, and the denominator of which is the sum of the outstanding principal amount of the Notes and such Pari Passu Debt (subject to proration in the event such amount is less than the aggregate Offered Price (as defined below) for all Notes tendered); and (2) to the extent required by such Pari Passu Debt, the Company will make an offer to purchase or otherwise repurchase or redeem Pari Passu Debt (a “Pari Passu Offer”) in an amount (the “Pari Passu Debt Amount”) equal to the excess of the Excess Proceeds over the Note Amount. However, in no event will the Company be required to make a Pari Passu Offer in a Pari Passu Debt Amount exceeding the principal amount of such Pari Passu Debt plus the amount of any premium required to be paid to repurchase such Pari Passu Debt. The offer price for the Notes will be payable in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest, if any, to, but not including, the date such Offer to Purchase is consummated (the “Offered Price”), in accordance with the procedures set forth in this Indenture. To the extent that the aggregate Offered Price of the Notes tendered pursuant to the Offer to Purchase is less than the Note Amount relating to the tendered Notes or the aggregate amount of Pari Passu Debt that is purchased in a Pari Passu Offer is less than the Pari Passu Debt Amount, the Company may use any remaining Excess Proceeds for general corporate purposes. If the aggregate principal amount of Notes and Pari Passu Debt surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Debt to be purchased on a pro rata basis; provided that, in the case of Global Notes, beneficial interests in such Notes shall be repurchased on a pro rata basis based on amounts tendered only if such proration is consistent with the procedures of the Depositary; otherwise, such beneficial interests shall be selected for repurchase in accordance with such procedures. Upon the completion of the purchase of all

55 the Notes tendered pursuant to an Offer to Purchase and the completion of a Pari Passu Offer, the amount of Excess Proceeds, if any, shall be reset at zero. (d) If the Purchase 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 and will not be paid as part of the Offered Price. If the Company becomes obligated to make an Offer to Purchase pursuant to this Section 4.10, the Notes (in amounts of $2,000 and integral multiples of $1,000 in excess thereof), and the Pari Passu Debt shall be purchased by the Company, at the option of the Holders thereof, in whole or in part, on a date that is not earlier than 30 days and not later than 60 days from the date the notice of the Offer to Purchase is given to Holders, or such later date as may be necessary for the Company to comply with the requirements under the Exchange Act. (e) The Company 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 an Offer to Purchase. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.10, the Company 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. SECTION 4.11. Limitation on Transactions with Affiliates. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or conduct any transaction (including the purchase, sale, lease or exchange of any property or asset or the rendering of any service) with any Affiliate of the Company involving aggregate payments or consideration in excess of $15.0 million (an “Affiliate Transaction”), unless: (1) the terms of such Affiliate Transaction, taken as a whole, are not materially less favorable to the Company or such Restricted Subsidiary, as the case may be, than those that could have reasonably been obtained by the Company or such Restricted Subsidiary in a comparable transaction at the time of such transaction in arms’ length dealings with a Person that is not an Affiliate or, if in the good faith judgment of the Board of Directors of the Company no comparable transaction is available with which to compare such Affiliate Transaction, such transaction is otherwise fair to the Company or such Restricted Subsidiary from a financial perspective; and (2) in the event such Affiliate Transaction involves an aggregate consideration in excess of $25.0 million, the terms of such transaction have been approved by a majority of the members of the Board of Directors of the Company and by a majority of the disinterested members of such Board of Directors (and such majority or majorities, as the case may be, determines that such Affiliate Transaction satisfies the criteria in clause (a)(1) of this Section 4.11). (b) The preceding requirements shall not apply to: (1) any transaction pursuant to agreements in effect on the Issue Date, as these agreements may be amended, modified, supplemented, extended or renewed from time to time, so long as any such amendment, modification, supplement, extension or renewal is not more disadvantageous to the Holders in any material respect in the good faith judgment of the Company, when taken as a whole, than the terms of the agreements in effect on the Issue Date; (2) any employment and severance arrangements between the Company or any of its Subsidiaries and their respective officers and employees in the ordinary course of business and transactions pursuant to equity incentive plans, stock option plans and employee benefit plans and arrangements;

56 (3) transactions between or among the Company and/or its Restricted Subsidiaries and any Guarantees issued by the Company or a Restricted Subsidiary for the benefit of the Company or a Restricted Subsidiary, as the case may be, in accordance with Section 4.9; (4) any agreement between any Person and an Affiliate of such Person existing at the time such Person is acquired by or merged into the Company or any of its Restricted Subsidiaries (provided that such agreement was not entered into in contemplation of such acquisition or merger) or any amendment thereto (so long as any such amendment when taken as a whole is not materially disadvantageous to the Holders in the good faith judgment of the Company as compared to such agreement as in effect on the date of such acquisition or merger); (5) the payment of customary fees and reasonable out-of-pocket costs to, and indemnities provided on behalf of, directors, managers, officers, employees and consultants of the Company and the Restricted Subsidiaries or any direct or indirect parent of the Company in the ordinary course of business to the extent attributable to the ownership or operation of the Company and the Restricted Subsidiaries; (6) any Restricted Payment or Permitted Investment that is permitted to be made pursuant to Section 4.7; and (7) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case, in the ordinary course of the business of the Company and its Restricted Subsidiaries and otherwise in compliance with the terms of this Indenture; provided that in the reasonable determination of the Company, such transactions are on terms when taken as a whole that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably have been obtained at the time of such transactions in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; (8) the grant, issuance or sale of Capital Stock (other than Disqualified Capital Stock) to Affiliates of the Company and the granting of registration rights and other customary rights in connection therewith; (9) transactions entered into by an Unrestricted Subsidiary with an Affiliate prior to the redesignation of any such Unrestricted Subsidiary as a Restricted Subsidiary pursuant to Section 4.16; provided that such transactions were not entered into in contemplation of such redesignation (10) any transaction to the extent the consideration paid by the Company or any Restricted Subsidiary consists of (i) Capital Stock (excluding Disqualified Capital Stock) of the Company or (ii) proceeds from the issuance and sale of Capital Stock (excluding Disqualified Capital Stock) of the Company within 180 days of such issuance and sale; (11) any transaction with a Person (other than an Unrestricted Subsidiary) that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns Capital Stock in or otherwise controls such Person; provided that, no Affiliate of the Company or any of its Subsidiaries other than the Company or a Restricted Subsidiary shall have a beneficial interest or otherwise participate in such Person; (12) transactions between the Company or any of its Restricted Subsidiaries and any Person that would constitute an Affiliate Transaction solely because such Person is a director or such Person has a director which is also a director of the Company; provided, however, that such director abstains from voting as a director of the Company on any matter involving such other Person;

57 (13) any transaction as to which the Company delivers to the Trustee a written opinion of an investment banking firm of national standing or other recognized independent expert with experience in appraising the terms and conditions of the type of transaction or series of related transactions for which an opinion is required stating that the terms of such transaction are not materially less favorable to the Company or such Restricted Subsidiary than those that could be obtained in a comparable arm’s-length transaction with an entity that is not an Affiliate; and (14) transactions in connection with Permitted Tax Restructurings. SECTION 4.12. Limitation on Liens. (a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume any Lien (other than a Permitted Lien) on any property or asset (including any intercompany notes) of the Company or a Restricted Subsidiary now owned or hereafter acquired, or assign or convey a right to receive any income or profits from such Liens, to secure (a) any Debt of the Company unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured for so long as such other Debt is so secured, or (b) any Debt of any Subsidiary Guarantor, unless prior to, or contemporaneously therewith, the Note Guarantee of such Subsidiary Guarantor is equally and ratably secured for so long as such other Debt is so secured; provided, however, that if such Debt is expressly subordinated to the Notes or a Note Guarantee, the Lien securing such Debt will be subordinated and junior to the Lien securing the Notes or such Note Guarantee, as the case may be, with the same relative priority as such Debt has with respect to the Notes or such Note Guarantee. (b) Notwithstanding the foregoing, any Lien securing the Notes or any Note Guarantee granted pursuant to this Section 4.12 will be automatically and unconditionally released and discharged upon the release by the holders of the Debt described in Section 4.12(a) of their Lien on the property or assets of the Company or any Restricted Subsidiary (including any deemed release upon payment in full of all obligations under such Debt), at such time as the holders of all such Debt release their Lien on the property or assets of the Company or such Restricted Subsidiary. SECTION 4.13. Offer to Purchase upon Change of Control. No later than 30 days after the occurrence of a Change of Control, the Company will be required to make an Offer to Purchase (a “Change of Control Offer”) all outstanding Notes at a purchase price equal to 101% of their principal amount plus accrued and unpaid interest, if any, to, but not including, the date of purchase (the “Change of Control Purchase Price”) (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of purchase). On or before the Purchase Date, the Company 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. On the Purchase Date, the Company will, to the extent lawful: (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 Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 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.

58 If the Purchase 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 and will not be paid as part of the Change of Control Purchase Price. The Company will not be required to make a Change of Control Offer upon a Change of Control if (i) 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 Company and purchases all Notes validly tendered and not validly withdrawn under such Change of Control Offer, (ii) a notice of redemption for all outstanding Notes has been given pursuant to Article III, unless and until there is a default in payment of the applicable redemption price or (iii) in connection with or in contemplation of any publicly announced Change of Control, the Company has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Purchase Price and has purchased all Notes validly tendered and not validly withdrawn in accordance with the terms of the Alternate Offer. The Company 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 Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.13, the Company 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 Company’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 or Alternate 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 the Change of Control Offer or Alternate Offer. SECTION 4.14. Corporate Existence. Subject to Article V, the Company 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 the Subsidiary Guarantors in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary Guarantor and the rights (charter and statutory), licenses and franchises of the Company and the Subsidiary Guarantors; provided that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of the Subsidiary Guarantors, if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company 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. Future Guarantees. If any Restricted Subsidiary that is not already a Subsidiary Guarantor Guarantees any Debt of the Company or a Subsidiary Guarantor under, or borrows Debt under, any of the Senior Secured Credit Facilities on or after the Issue Date, then such Restricted Subsidiary shall execute, within 30 days of the date on which it became a guarantor or borrower with respect to such other Debt, a supplemental indenture in substantially the form attached hereto as Exhibit B, pursuant to which such Restricted Subsidiary shall become a Subsidiary Guarantor with respect to the Notes, upon the terms and subject to the release provisions and other limitations set forth in Article X. SECTION 4.16. Designation of Restricted and Unrestricted Subsidiaries. (a) The Company may designate any Restricted Subsidiary to be an “Unrestricted Subsidiary”, in which event such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary, if (1) neither the Company nor any of its other Subsidiaries (other than another Unrestricted Subsidiary) provides credit support for, or a Guarantee of, any Debt of such Subsidiary or any Subsidiary of such Subsidiary (including any undertaking, agreement or

59 instrument evidencing such Debt) or is directly or indirectly liable for any Debt of such Subsidiary or any Subsidiary of such Subsidiary, and no default with respect to any Debt of such Subsidiary or any Subsidiary of such Subsidiary (including any right which the holders thereof may have to take enforcement action against such Subsidiary) would permit (upon notice, lapse of time or both) any holder of any other Debt of the Company and its Subsidiaries (other than another Unrestricted Subsidiary) to declare a default on such other Debt or cause the payment thereof to be accelerated or payable prior to its final scheduled maturity, (2) such Subsidiary does not own any Capital Stock of, or does not own or hold any Lien on any property of, any other Restricted Subsidiary which is not a Subsidiary of the Subsidiary to be so designated or otherwise an Unrestricted Subsidiary, (3) at the time of designation, the Company could make a Restricted Payment or Permitted Investment in an amount equal to the greater of the Fair Market Value and book value of its interest in such Subsidiary pursuant to Section 4.7, and (4) no Default or Event of Default shall have occurred and be continuing at the time of, or immediately after giving effect to, such designation. Any such designation will become effective upon the delivery to the Trustee of an Officer’s Certificate identifying the Restricted Subsidiary that has been designated as an Unrestricted Subsidiary and certifying that the foregoing conditions have been satisfied. (b) The Company may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company if (1) (a) the Company would be able to Incur at least $1.00 of additional Debt pursuant to Section 4.9(a), or (b) the Consolidated Coverage Ratio of the Company on a Pro Forma Basis taking into account such designation would not be less than the Consolidated Coverage Ratio of the Company immediately prior to such designation; (2) all Liens of such Unrestricted Subsidiary outstanding immediately following such designation would, if Incurred at such time, have been permitted to be Incurred for all purposes of this Indenture; and (3) no Default or Event of Default would occur and be continuing following such designation. Any such designation will become effective upon the delivery to the Trustee of an Officer’s Certificate identifying the Unrestricted Subsidiary that has been designated as a Restricted Subsidiary and certifying that the foregoing conditions have been satisfied. SECTION 4.17. Covenant Suspension. (a) If on any date following the Issue Date, the Notes have achieved Investment Grade Status and no Default or Event of Default has occurred and is then continuing, then, upon delivery by the Company to the Trustee of an Officer’s Certificate to the foregoing effect (such date, a “Suspension Date”), the Company and the Restricted Subsidiaries will no longer be subject to the following covenants: (1) Section 4.7; (2) Section 4.8; (3) Section 4.9; (4) Section 4.10; (5) Section 4.11; (6) Section 4.15 (but only with respect to any Person that is required to become a Subsidiary Guarantor during the applicable Suspension Period); and (7) Section 5.1(a)(3). During any period that the foregoing covenants (the “Suspended Covenants”) have been suspended (the “Suspension Period”), the Board of Directors of the Company shall not designate any of the Company’s Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.16, unless such designation would have complied with Section 4.7 and Section 4.16, as if such Sections were in effect during the Suspension Period.

60 (b) Notwithstanding the foregoing, on the date that the Notes cease to have Investment Grade Status from at least two of the Rating Agencies (such date, a “Reinstatement Date”), the foregoing covenants will be reinstated as of the Reinstatement Date. Any Debt Incurred during the Suspension Period will be classified as having been Incurred pursuant to Section 4.9(a) or one of the clauses of Section 4.9(b). To the extent such Debt would not be so permitted to be Incurred, such Debt will be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.9(b)(2). Calculations under the reinstated Section 4.7 will be made as if Section 4.7 had been in effect since the Issue Date. In addition, for purposes of Section 4.11, all agreements and arrangements entered into by the Company and any Restricted Subsidiary with an Affiliate of the Company during the Suspension Period will be deemed to have been entered into on or prior to the Issue Date and for purposes of Section 4.8, all contracts entered into during the Suspension Period that contain any of the restrictions contemplated by such covenant will be deemed to have been existing on the Issue Date. During the Suspension Period, any reference in the definitions of “Permitted Liens” and “Unrestricted Subsidiary” to Section 4.9 or any provision thereof shall be construed as if such covenant were in effect during the Suspension Period. Upon the occurrence of a Suspension Period, the amount of Excess Proceeds from Net Available Proceeds shall be reset at zero. (c) Notwithstanding that the Suspended Covenants may be reinstated, no Default or Event of Default will be deemed to have occurred with respect to the suspended covenants as a result of any actions taken by the Company or its Restricted Subsidiaries or other events that occurred during the Suspension Period (or upon termination of the Suspension Period or after that time arising out of events that occurred or actions taken during the Suspension Period) and the Company and any Restricted Subsidiary will be permitted, without causing a Default or Event of Default or breach of any kind under this Indenture, to honor, comply with or otherwise perform any contractual commitments or obligations entered into during a Suspension Period following a reinstatement of the Suspended Covenants (provided that any such contractual commitments or obligations were not Incurred in contemplation of any such reinstatement). (d) Promptly following the occurrence of any suspension or reinstatement of the covenants as described above, the Company shall provide an Officer’s Certificate to the Trustee regarding such occurrence. The Trustee shall have no obligation to independently determine or verify if a suspension or reinstatement has occurred or notify the Holders of any suspension or reinstatement. The Trustee may provide a copy of such Officer’s Certificate to any Holder of the Notes upon request. ARTICLE V SUCCESSORS SECTION 5.1. Consolidation, Merger, Conveyance, Transfer or Lease. (a) The Company shall not consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets in a single transaction or series of related transactions to, another Person, unless: (1) the resulting, surviving or transferee Person (the “Successor Company”) shall be a corporation, partnership, trust or limited liability company organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Company (if not the Company) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Company under this Indenture and the Notes; (2) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; (3) except in the case of any such consolidation or merger of the Company with or into a Restricted Subsidiary, immediately after giving Pro Forma Effect to such transaction and treating any Debt which becomes an obligation of the Company or a Restricted Subsidiary as a result

61 of such transaction as having been Incurred by the Company or such Restricted Subsidiary at the time of the transaction, either (i) the Company (including any Successor Company) could Incur at least $1.00 of additional Debt (other than Permitted Debt) pursuant to Section 4.9(a), or (ii) the Consolidated Coverage Ratio of the Company or such Successor Company is not less immediately after such transaction than it was immediately before such transaction; (4) if the Company is not the Successor Company, at the time of such transaction, each Subsidiary Guarantor will have by supplemental indenture confirmed that its Note Guarantee shall apply to the Successor Company’s obligations under this Indenture and the Notes; and (5) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture, if any, comply with this Indenture. Notwithstanding Section 5.1(a)(3), (i) any Restricted Subsidiary may consolidate with or merge with or into, or convey, transfer or lease all or substantially all its assets in a single transaction or series of related transactions to the Company so long as no Capital Stock of the Restricted Subsidiary is distributed to any Person other than the Company; provided that, in the case of a Restricted Subsidiary that merges into the Company, the Company will not be required to comply with Section 5.1(a)(5); and (ii) the Company may merge with an Affiliate of the Company solely for the purpose of reincorporating or forming the Company in another State of the United States or the District of Columbia, so long as the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby. For purposes of this Section 5.1(a), the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of the Company. Except as set forth below under Section 5.1(b), this Section 5.1 shall not restrict, and shall not be applicable to, the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Restricted Subsidiaries of the Company to one or more Restricted Subsidiaries of the Company or any consolidation, merger or amalgamation with, between or among Restricted Subsidiaries of the Company. The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture, and, except in the case of a lease of all or substantially all its assets, the Company will be released from the obligation to pay the principal of, and interest on, the Notes and all other obligations under this Indenture. (b) Except in circumstances under which this Indenture provides for the release of Note Guarantees as described under Section 10.5, each Subsidiary Guarantor will not, and the Company will not permit a Subsidiary Guarantor to, consolidate with or merge with or into, or convey or transfer or lease all or substantially all its assets to, another Person (other than the Company or another Subsidiary Guarantor), unless at the time and after giving effect thereto: (1) (A) the resulting, surviving or transferee Person (the “Successor Subsidiary Guarantor”) shall be a corporation, limited partnership, trust, limited liability company or other entity and, other than with respect to a Subsidiary Guarantor that is a Foreign Subsidiary, organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and the Successor Subsidiary Guarantor (if not the Subsidiary Guarantor) shall expressly assume, by supplemental indenture, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, all the obligations of the Subsidiary Guarantor under this Indenture and its Note Guarantee;

62 (B) immediately after giving effect to such transaction no Default or Event of Default shall have occurred and be continuing; and (C) the Subsidiary Guarantor or the Successor Subsidiary Guarantor, as the case may be, shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture, if any, comply with this Indenture; or (2) such transaction does not violate Section 4.10. Notwithstanding the foregoing, any Subsidiary Guarantor may merge with or into or transfer all or part of its properties and assets to a Subsidiary Guarantor or merge with a Restricted Subsidiary of the Company, so long as the resulting entity remains or becomes a Subsidiary Guarantor. For purposes of this Section 5.1(b), the sale, lease, conveyance, assignment, transfer, or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of a Subsidiary Guarantor, which properties and assets, if held by such Subsidiary Guarantor instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of such Subsidiary Guarantor on a consolidated basis, shall be deemed to be the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of such Subsidiary Guarantor. The Successor Subsidiary Guarantor will succeed to, and be substituted for, and may exercise every right and power of, the Subsidiary Guarantor under this Indenture, and, except in the case of a lease of all or substantially all its assets, the Subsidiary Guarantor will be released from its obligations under its Note Guarantee. ARTICLE VI DEFAULTS AND REMEDIES SECTION 6.1. Events of Default. (a) Each of the following is an “Event of Default”: (1) failure to pay principal of (or premium, if any, on) any Note when due and payable, at maturity, upon redemption or otherwise; (2) failure to pay any interest on any Note when due and payable and such default continues for 30 days; (3) default in the payment of principal, premium and interest on Notes required to be purchased pursuant to an Offer to Purchase as described under Section 4.10 and Section 4.13 when due and payable; (4) failure to perform or comply with the provisions described under Section 5.1; (5) failure to perform any other covenant or agreement of the Company under this Indenture or the Notes and such default continues for 60 days (or 90 days with respect to Section 4.3) after written notice to the Company by the Trustee or Holders of at least 25% in aggregate principal amount of outstanding Notes; (6) default under the terms of any instrument evidencing or securing any Debt of the Company or any Restricted Subsidiary having an outstanding principal amount of $50.0 million, individually or in the aggregate, which default (i) results in the acceleration of the payment of such Debt or (ii) constitutes the failure to pay all or any portion of the principal amount of such Debt when due (after any applicable grace periods);

63 (7) the rendering of one or more final judgments, orders or decrees (not subject to appeal) of any court or regulatory or administrative agency against the Company or any Restricted Subsidiary or any of their respective properties in an amount in excess of $50.0 million, either individually or in the aggregate (exclusive of any portion of any such payment covered by third-party insurance) which remains undischarged or unstayed for a period of 60 days after the date on which the right to appeal has expired; (8) the Company, any Restricted Subsidiary that is a Significant Subsidiary of the Company or any group of Restricted Subsidiaries of the Company that, taken together (as of the latest audited consolidated financial statements for the Company and its Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case, (B) consents to the entry of an order for relief against it in an involuntary case, (C) consents to the appointment of a custodian of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors. (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (i) is for relief against the Company or any Restricted Subsidiary that is a Significant Subsidiary of the Company or any group of Restricted Subsidiaries of the Company that, taken together (as of the latest audited consolidated financial statements for the Company and its Subsidiaries), would constitute a Significant Subsidiary, in an involuntary case; (ii) appoints a custodian of the Company or any Restricted Subsidiary that is a Significant Subsidiary of the Company or any group of Restricted Subsidiaries of the Company that, taken together (as of the latest audited consolidated financial statements for the Company and its Subsidiaries), would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any Restricted Subsidiary that is a Significant Subsidiary of the Company or any group of Restricted Subsidiaries of the Company that, taken together (as of the latest audited consolidated financial statements for the Company and its Subsidiaries), would constitute a Significant Subsidiary; or (iii) orders the liquidation of the Company or any Restricted Subsidiary that is a Significant Subsidiary of the Company or any group of Restricted Subsidiaries of the Company that, taken together (as of the latest audited consolidated financial statements for the Company and its Subsidiaries), would constitute a Significant Subsidiary and, in each case, the order or decree remains unstayed and in effect for 60 consecutive days; or (10) the Note Guarantee of any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that together would constitute a Significant Subsidiary is held by a final non- appealable order or judgment of a court of competent jurisdiction to be unenforceable or invalid or ceases for any reason to be in full force and effect (other than in accordance with the terms of this Indenture) or any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that together would constitute a Significant Subsidiary or any Person acting on behalf of any such Subsidiary Guarantor or such group of Subsidiary Guarantors denies or disaffirms its or their obligations under its or their Note Guarantee (other than by reason of a release of such Subsidiary Guarantor or such group of Subsidiary Guarantors from its or their Note Guarantee in accordance with the terms of this Indenture).

64 (b) In the event of any Event of Default specified in Section 6.1(a)(6), such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 30 days after such Event of Default arose: (1) either (i) the Debt or guarantee that is the basis for such Event of Default has been discharged, (ii) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (iii) the default that is the basis for such Event of Default has been cured; and (2) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction. SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default specified in clauses (8) or (9) of Section 6.1(a)) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Company, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Company and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the outstanding Notes shall become due and payable immediately. At any time after such acceleration pursuant to this Section 6.2, 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: (1) the rescission would not conflict with any judgment or decree; (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; (4) the Company has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances; and (5) in the event of the cure or waiver of an Event of Default specified in clauses (8) or (9) of Section 6.1(a), the Trustee shall have received an Officer’s Certificate and an Opinion of Counsel that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. If an Event of Default specified in clauses (8) or (9) of Section 6.1(a) occurs, then all 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. 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, and 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.

65 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 on, or the principal of, the Notes (other than any such payment that has become due because of an acceleration that has been rescinded). 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 or power conferred on it. However, (i) the Trustee may require security or indemnity satisfactory to it be furnished prior to taking such actions, (ii) the Trustee may refuse to follow any direction that conflicts with law or this Indenture 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 or that would involve any personal liability for the Trustee and (iii) the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from the Holders. SECTION 6.6. Limitation on Suits. Subject to Section 6.7, no Holder of a Note will have any right to institute any proceeding with respect to this Indenture, or for the appointment of a receiver or a Trustee, or for any other remedy hereunder unless (a) such Holder has previously given to the Trustee written notice of a continuing Event of Default with respect to the Notes, (b) the Holders of at least 25% in aggregate principal amount of the outstanding Notes have made written request, and such Holder or Holders have offered to the Trustee indemnity satisfactory to the Trustee to institute such proceeding as Trustee, (c) the Trustee has failed to institute such proceeding, and (d) the Trustee has not received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request, within 60 days after such notice, request and offer. 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 contractual right of any Holder to receive payment of principal of, premium 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 modified or amended in a manner adverse to such Holder 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(a) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as Trustee of an express trust against the Company for the whole amount of principal of, premium, if any, 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 Company (or any other obligor upon the Notes including the Subsidiary Guarantors), 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 7.6. 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 7.6 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

66 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 7.6, 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 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, 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 Company 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. SECTION 6.12. Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted. SECTION 6.13. Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.7 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. SECTION 6.14. Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

67 ARTICLE VII TRUSTEE SECTION 7.1. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. (b) Except during the continuance of an Event of Default: (1) the duties of the Trustee shall be determined solely by the express provisions of this Indenture 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 grossly negligent action, its own grossly 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 Company. 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. SECTION 7.2. Rights of Trustee. (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 or PDF transmission) 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.

68 (b) Before the Trustee acts or refrains from acting, it may require an Officer’s 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 Officer’s Certificate or Opinion of Counsel. Prior to taking, suffering or omitting 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 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 discretion or 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 Company or a Subsidiary Guarantor shall be sufficient if signed by an Officer of the Company or such Subsidiary 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 Company, personally or by agent or attorney at the sole cost of the Company, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation. (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 Company and each of the Subsidiary Guarantors shall deliver to the Trustee an Officer’s Certificate setting forth the names of individuals and/or titles of Officers of the Company and each Subsidiary Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture, the Notes and the Note Guarantees, which Officer’s Certificate may be signed by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded. (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 (i) actual knowledge of a payment Default under Sections 6.1(a)(1), 6.1(a)(2) and 6.1(a)(3) or (ii) received from the Company or Subsidiary Guarantor or from any Holder written notice thereof at its address set forth in Section 11.1 and such notice references the Notes and this Indenture. In the absence of 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.

69 (l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder. (m) No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties thereunder, or in the exercise of any of its rights or powers. (n) In the case of any conflict between the Notes and this Indenture, the provisions of this Indenture shall control and govern. (o) The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures. 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 Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.9. 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 Note Guarantee; it shall not be accountable for the use of the proceeds from the Notes or any money paid to the Company or upon the Company’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 Officer’s 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 the Trustee has notice or knowledge thereof as provided in Section 7.2(j), 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 on any Note, the Trustee may withhold the notice if and so long

70 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 the withholding of such notice is in the interest of the Holders. SECTION 7.6. Compensation and Indemnity. The Company 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 Company 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 Company and the Subsidiary Guarantors, jointly and severally, shall indemnify, defend, protect and hold the Trustee (which for purposes of this Section 7.6 shall include its officers, directors, employees and agents) harmless against any and all claims, damages, losses, liabilities, costs or expenses suffered or 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 Company or any Subsidiary Guarantor (including this Section 7.6) and defending itself against any claim (whether asserted by the Company 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 have been found by a court of competent jurisdiction in a non-appealable final decision to have been caused by its own gross negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Trustee may have one separate counsel, and the Company shall pay the reasonable fees and expenses of such counsel for the Trustee. The Company and the Subsidiary Guarantors need not pay for any settlement made without the consent of the Company, which consent shall not be unreasonably withheld. The obligations of the Company and the Subsidiary Guarantors under this Section 7.6 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 Company’s payment obligations in this Section 7.6, 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 clauses (8) or (9) of Section 6.1(a) 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. SECTION 7.7. 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 7.7. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee upon thirty days’ written notice to the Trustee and the Company. The Company may remove the Trustee if no Event of Default exists and: (a) 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; (b) a custodian or public officer takes charge of the Trustee or its property; or (c) the Trustee becomes incapable of acting. If the Trustee acquires any conflicting interest, it must eliminate such conflict within 90 days or resign.

71 If the Trustee resigns or is removed or if a vacancy exists in the office of the Trustee for any reason, the Company 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 Company. 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 Company), the Company 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 7.9, 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 Company. 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 7.6. Notwithstanding replacement of the Trustee pursuant to this Section 7.7, the Company’s and the Subsidiary Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee. SECTION 7.8. 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 the trust hereby created) to, another corporation, the successor corporation without any further act shall be the successor Trustee or Agent, as applicable. SECTION 7.9. 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. ARTICLE VIII DEFEASANCE; DISCHARGE OF THIS INDENTURE SECTION 8.1. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, by delivery of an Officer’s 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 Company’s exercise under Section 8.1 of the option applicable to this Section 8.2, the Company and the Subsidiary Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Note Guarantees and this Indenture on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Subsidiary Guarantors shall be deemed to have paid and discharged all of the obligations with respect to this Indenture, the Notes and the Note 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 their other obligations under such Notes, Note Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Company, shall execute instruments acknowledging the same), and this Indenture shall cease to be of further effect as to all such Notes and Note 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 on, such Notes when such payments are due from the trust funds referred to in Section 8.4(1); (b) the Company’s obligations with respect to such Notes under Section 2.2, Section 2.3, Section

72 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 7.6, Section 8.5 and Section 8.7 and the obligations of the Company and the Subsidiary Guarantors in connection therewith; and (d) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Company 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 Company’s exercise under Section 8.1 of the option applicable to this Section 8.3, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.4 below, be released from its obligations under Sections 4.3, 4.7 through Section 4.16 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 and the Note Guarantees shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company 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, and the Events of Default in clauses (3) through (7) or (8) of Section 6.1(a) (with respect to any Subsidiary) and Section 6.1(a)(9) (with respect to any Subsidiary) shall no longer apply but, except as specified above, the remainder of this Indenture and such Notes and any Note Guarantees shall be unaffected thereby. 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 Company must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S. dollars, non-callable U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest (if U.S. Government Obligations are deposited, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Company and delivered to the Trustee), to pay the principal of, premium, if any, and 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, and any other amounts owing under this Indenture (in the case of an optional redemption date prior to electing to exercise either Legal Defeasance or Covenant Defeasance, the Company has delivered to the Trustee an irrevocable notice to redeem all of the outstanding Notes on such redemption date); (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel from counsel in the United States confirming that, subject to customary assumptions and exclusions: (A) the Company has received from, or there has been published by, the United States Internal Revenue Service a ruling; or (B) since the Issue Date, 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, subject to customary assumptions and exclusions, the beneficial owners 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 Company shall have delivered to the Trustee an Opinion of Counsel from counsel in the United States confirming that, subject to customary assumptions and exclusions, the beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S.

73 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 such Covenant Defeasance had not occurred; (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit (and any similar concurrent deposit relating to other Debt) (and the Incurrence of Liens associated with any such borrowings)); (5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture and the agreements governing any other Debt being defeased, discharged or replaced) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; (6) the Company shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and (7) the Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that the applicable 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 Company 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, if any, but such money need not be segregated from other funds except to the extent required by law. The Company 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 Section 8.8 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 Company from time to time upon the written request of the Company 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 Company. Subject to applicable escheat laws, any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall be paid to the Company on its written request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as Trustee thereof, shall thereupon cease; provided,

74 however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense and written request of the Company 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 Company. 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 Company and the Subsidiary 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 Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company 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 and Note Guarantees when either: (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 Company and thereafter repaid to the Company or discharged from this trust), have been delivered to the Trustee for cancellation; or (2) (a) 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 Article III and, in any case, the Company or any Subsidiary Guarantor 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 in such amounts as will be sufficient without consideration of any reinvestment of interest (if U.S. Government Obligations are deposited, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Company and delivered to the Trustee) to pay and discharge the entire Debt (including all principal and accrued interest, if any) on the Notes not theretofore delivered to the Trustee for cancellation; (b) the Company or any Subsidiary Guarantor has paid or caused to be paid all other sums payable by the Company under this Indenture; and (c) the Company 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 Company must deliver an Officer’s 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 Company’s and the Subsidiary Guarantors’ obligations in Section 7.6, 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 Officer’s Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Company’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

75 ARTICLE IX AMENDMENT, SUPPLEMENT AND WAIVER SECTION 9.1. Without Consent of Holders of the Notes. Notwithstanding Section 9.2, without the consent of any Holders, the Company, the Subsidiary Guarantors and the Trustee, at any time and from time to time, may amend or supplement this Indenture, the Note Guarantees or the Notes issued hereunder for any of the following purposes: (1) to evidence the succession of another Person to the Company or a Subsidiary Guarantor under this Indenture, Notes or the applicable Note Guarantee, and the assumption by any such successor of the covenants of the Company or such Subsidiary Guarantor under this Indenture, Notes and in such Note Guarantee in accordance with Section 5.1; (2) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit of the Holders of the Notes or to surrender any right or power conferred upon the Company or any Subsidiary Guarantor, as applicable, in this Indenture, in the Notes or in any Note Guarantee; (3) to cure any ambiguity, or to correct or supplement any provision in this Indenture or in any supplemental indenture, the Notes or any Note Guarantee which may be defective or inconsistent with any other provision in this Indenture, the Notes or any Note Guarantee; (4) to make any change that would provide any additional rights or benefits to the Holders of the Notes; (5) to make any other provisions with respect to matters or questions arising under this Indenture, the Notes or any Note Guarantee; provided that, in each case, such provisions shall not adversely affect the rights of the Holders of the Notes in any material respect; (6) to comply with the requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act of 1939 (15 U.S. Code §§ 77aaa-77bbbb), as amended, if applicable; (7) to add a Subsidiary Guarantor under this Indenture or otherwise provide a Note Guarantee of the Notes; (8) to evidence and provide the acceptance of the appointment of a successor Trustee under this Indenture; (9) to mortgage, pledge, hypothecate or grant a security interest in favor of the Trustee for the benefit of the Holders of the Notes as security for the payment and performance of the Company’s and any Subsidiary Guarantor’s obligations under this Indenture, in any property, or assets; (10) to provide for the issuance of Additional Notes under this Indenture in accordance with the terms and subject to the limitations set forth in this Indenture; (11) to comply with the rules of any applicable Depositary; or (12) to conform the text of this Indenture, the Notes or the Note Guarantees to any provision of the “Description of notes” section of the Offering Memorandum, as certified in an Officer’s Certificate delivered to the Trustee. After an amendment under this Indenture becomes effective, the Company 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.

76 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 Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Notes or any Note Guarantees or waive any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes or the Note Guarantees; 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): (1) change the Stated Maturity of the principal of, or any installment of interest on, any Note; (2) reduce the principal amount of (or the premium), or rate of interest on, any Note; (3) change the place or currency of payment of principal of (or premium), or interest on, any Note; (4) impair the right to institute suit for the enforcement of any payment of principal of (or premium), or interest on, any Note, or waive any payment in respect thereof except a default in payment arising solely from an acceleration of the Notes that has been rescinded; (5) modify any provisions of this Indenture relating to the modification and amendment of this Indenture or the waiver of past defaults or covenants which require each Holder’s consent; (6) amend any provisions relating to the redemption of the Notes (other than notice provisions), it being understood that, for the avoidance of doubt, the provisions described under Section 4.10 and Section 4.13 shall not be covered by this clause; (7) modify the Note Guarantees in any manner adverse to the Holders, except in accordance with this Indenture; or (8) modify any of the provisions of this Indenture or the related definitions affecting the ranking of the Notes. 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. 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 Company may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver. SECTION 9.4. 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 Company 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.

77 SECTION 9.5. 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 Officer’s 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. ARTICLE X NOTE GUARANTEES SECTION 10.1. Note Guarantees. (a) Each Subsidiary Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Company 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 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, to the extent lawful, and all other obligations of the Company 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 Note Guarantees shall be a guarantee of payment and not of collection. (b) Each Subsidiary 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 Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Subsidiary Guarantor. (c) Each Subsidiary 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 Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands whatsoever and covenants that the Note Guarantee of such Subsidiary 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 Note Guarantee. Each of the Subsidiary 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 Subsidiary Guarantors to enforce each such Subsidiary Guarantor’s Note Guarantee without first proceeding against the Company or any other Subsidiary Guarantor. Each Subsidiary 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 Subsidiary 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 Company or any Subsidiary Guarantor, or any custodian, Trustee, liquidator or other similar official acting in relation to the Company or any Subsidiary Guarantor, any amount paid by any of them to the Trustee or such Holder, the Note Guarantee of each of the Subsidiary Guarantors, to the extent theretofore discharged, shall be

78 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 Subsidiary Guarantor further agrees that, as between each Subsidiary 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 Note Guarantee of such Subsidiary 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 Subsidiary Guarantor for the purpose of the Note Guarantee of such Subsidiary Guarantor. (f) Each Subsidiary Guarantor that makes a payment for distribution under its Note Guarantee is entitled upon payment in full of all guaranteed obligations under this Indenture to seek contribution from each other Subsidiary Guarantor in a pro rata amount of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment in accordance with GAAP. SECTION 10.2. Execution and Delivery of Guarantee. To evidence its Note Guarantee set forth in Section 10.1, each Subsidiary 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 Subsidiary Guarantor by an Officer of such Subsidiary Guarantor (or, if an officer is not available, by a board member or director or other duly authorized signatory) on behalf of such Subsidiary Guarantor. Each Subsidiary Guarantor hereby agrees that its Note 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 Note Guarantee on the Notes. In case the Officer, board member or director of such Subsidiary 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 Note Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors. SECTION 10.3. Severability. In case any provision of any Note 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 Subsidiary Guarantors’ Liability. Each Subsidiary Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Note Guarantee of such Subsidiary 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 Subsidiary Guarantors hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Note Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, without limitation, any guarantees under the Senior Secured Credit Facilities) and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Note Guarantee, result in the obligations of such Subsidiary Guarantor under its Note Guarantee constituting a fraudulent conveyance, fraudulent preference or fraudulent transfer or otherwise reviewable under applicable law. SECTION 10.5. Releases. A Note Guarantee of a Subsidiary Guarantor shall be automatically and unconditionally released and discharged upon: (a) any sale, transfer or other disposition of all or substantially all of the assets of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or

79 after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does not violate Section 4.10 of this Indenture; (b) any sale, transfer or other disposition of Capital Stock of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if after such sale, transfer or disposition, the Subsidiary Guarantor would cease to be a Restricted Subsidiary and the sale or other disposition does not violate Section 4.10 of this Indenture; (c) the exercise by the Company of its Legal Defeasance option or its Covenant Defeasance option or the satisfaction and discharge of this Indenture, in each case as provided under Article VIII; (d) the proper designation of such Subsidiary Guarantor by the Company as an Unrestricted Subsidiary in accordance with the terms of this Indenture; (e) the Subsidiary Guarantor ceasing to Guarantee any Debt or be a borrower under each of the Senior Secured Credit Facilities and no Event of Default has occurred and is continuing, except a release or discharge by or as a result of payment under such Note Guarantee; or (f) a Suspension Date; provided that the Note Guarantees shall be reinstated upon a Reinstatement Date. Upon delivery to the Trustee of an Officer’s Certificate and an Opinion of Counsel to the effect that all conditions precedent to the release of a Subsidiary Guarantor’s Note Guarantee set forth in this Indenture have been satisfied, the Trustee shall execute any documents reasonably requested by the Company in writing in order to evidence the release of any Subsidiary Guarantor from its obligations under its Note Guarantee. Any Subsidiary Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Subsidiary Guarantor under this Indenture as provided in this Article X. SECTION 10.6. Benefits Acknowledged. Each Subsidiary 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 Note Guarantee are knowingly made in contemplation of such benefits.

82 SECTION 11.10. Execution in Counterparts. This Indenture may be executed in two or more counterparts, which when so executed shall constitute one and the same agreement. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Indenture or any document to be signed in connection with this Indenture shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means. The Trustee shall have the right to accept and act upon any notice, instruction, or other communication, including any funds transfer instruction, (each, a “Notice”) received pursuant to this Indenture by electronic transmission (including by e-mail, facsimile transmission, web portal or other electronic methods) and shall not have any duty to confirm that the person sending such Notice is, in fact, a person authorized to do so. Electronic signatures believed by the Trustee to comply with the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten signatures and digital signatures provided by DocuSign, Orbit, Adobe Sign or any other digital signature provider identified by any other party hereto and acceptable to the Trustee) shall be deemed original signatures for all purposes. Each other party to this Indenture assumes all risks arising out of the use of electronic signatures and electronic methods to send Notices to the Trustee, including without limitation the risk of the Trustee acting on an unauthorized Notice and the risk of interception or misuse by third parties. Notwithstanding the foregoing, the Trustee may in any instance and in its sole discretion require that an original document bearing a manual signature be delivered to the Trustee in lieu of, or in addition to, any such electronic Notice.

SECTION 11.12. Acts of Holders. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by 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 Company. 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 Company, if made in the manner provided in this Section 11.12. (b) The fact and date of the execution by any Person of any such instrument or writing may be proved (1) 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 or (2) in any other manner reasonably deemed sufficient by the Trustee. 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. (c) The ownership of Notes shall be proved by the register maintained by the Registrar hereunder.

83 (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 Company in reliance thereon, whether or not notation of such action is made upon such Note. (e) If the Company shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by or pursuant to an Officer’s Certificate, 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 Company 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. (f) The Trustee may, but shall not be obligated to, set any day as a record date for the purpose of determining the Holders entitled to join in the giving or making of (1) any notice of default under Section 6.1, (2) any declaration of acceleration referred to in Section 6.2, (3) any direction referred to in Section 6.5 or (4) any request to pursue a remedy as permitted in Section 6.6. If any record date is set pursuant to this paragraph, the Holders on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless made, given or taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Notes or each affected Holder, as applicable, on such record date. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company and to each Holder in the manner set forth in Section 11.1. (g) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part. (h) Without limiting the generality of the foregoing, a Holder, including a Depositary that is the Holder of a Global Note, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such Depositary’s standing instructions and customary practices. (i) The Company may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Note held by a Depositary entitled under the procedures of such Depositary, if any, to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders; provided that if such a record date is fixed, only the beneficial owners of interests in such Global Note on such record date or their duly appointed proxy or proxies shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such beneficial owners remain beneficial owners of interests in such Global Note after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be effective hereunder unless made, given or taken on or prior to the applicable Expiration Date.

84 (j) With respect to any record date set pursuant to this Section 11.12, the party hereto that sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Notes in the manner set forth in Section 11.1, on or prior to both the existing and the new Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section 11.12, the party hereto which set such record date shall be deemed to have initially designated the 90th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this clause (j). SECTION 11.13. Force Majeure. In no event shall the Trustee or any 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 work 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 and each Agent 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 11.14. 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. SECTION 11.15. USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account. The Company agrees that it will provide the Trustee with information about the Company as the Trustee may reasonably request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act. SECTION 11.16. OFAC. Each of the Subsidiary Guarantors and the Company covenants and represents that neither they nor any of their affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the U.S. Government (including the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”)), the United Nations Security Council, the European Union, HM Treasury, or other relevant sanctions authority (collectively “Sanctions”). Each of the Subsidiary Guarantors and the Company covenants and represents that neither they nor any of their affiliates, subsidiaries, directors or officers will use any payments made pursuant to this Indenture, (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of Sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any person.

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 Company 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 (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.
