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

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

51

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

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of beneficial owners in a Global Note may be transferred in accordance with Section 2.15 and the rules and procedures of the Depositary. In addition, certificated Notes shall be transferred to beneficial owners in exchange for their beneficial interests only if (i) the Depositary notifies the Issuer that it is unwilling or unable to continue as Depositary for the Global Notes and a successor depositary is not appointed by the Issuer 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 Issuer 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 Issuer, 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 Issuer shall execute, and the Trustee shall authenticate and deliver to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Note an equal aggregate principal amount of certificated Notes of authorized denominations.

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

(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 Issuer 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.

52

(2) No service charge shall be made to a Holder for any registration of transfer or exchange, but Holders will be required to pay all taxes due on such transfer or exchange (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 Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes (or interests therein) or certificated Notes surrendered upon such registration of transfer or exchange.

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

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

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

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

(8) Neither the Trustee nor any Agent shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Participants or beneficial owners of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

53

(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, the Registrar or the Issuer and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuer 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 Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer, the Trustee and the Agents may charge for their expenses in replacing a Note.

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

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

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 Holdings, the Issuer, 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 Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity.

54

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

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

SECTION 2.11. Cancellation. The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Sections 2.7 and 2.16, the Issuer may not issue new Notes to replace Notes that it has redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice.

SECTION 2.12. Defaulted Interest. If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but in all events at least five Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1; provided that no special record date shall be required with respect to any defaulted interest that is paid within the applicable grace period. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least 15 days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 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 Issuer 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 Issuer shall promptly notify the Trustee in writing of any change in the CUSIP number and ISIN number.

55

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 the later of the date of its original issue, the original issue date of any Additional Notes and the last date on which the Issuer or any Affiliate of the Issuer was the owner of such securities (or any predecessor thereto) (the “Resale Restriction Termination Date”):

56

(b) The following provisions shall apply with respect to any proposed transfer of a Regulation S Note prior to the date which is 40 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 Issuer 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 Issuer 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 Issuer or the Trustee, receipt by the Trustee or its agent of an Opinion of Counsel, certification and/or other information satisfactory to each of them.

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

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

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

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

SECTION 2.16. Issuance of Additional Notes. The Issuer shall be entitled to issue Additional Notes, without the consent of Holders, 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 Issuer, such Additional Notes will have a separate CUSIP and ISIN numbers.

The Trustee shall, upon receipt of such Officers’ Certificate and Authentication Order (which may be included in the Officers’ 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 Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7, it shall furnish to the Trustee, at least five Business Days (or such shorter period as is acceptable to the Trustee) before sending a notice of such redemption, an Officers’ Certificate setting forth the (i) the paragraph of the Notes and/or section of this Indenture pursuant to which the redemption shall occur, (ii) redemption date (which, in the case of a redemption subject to conditions, may be subject to extension until such conditions are satisfied), (iii) 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 a national security exchange, on a pro rata basis (except that any Notes represented by a Global Note will be redeemed by such method the Depositary may require); provided, however, that no Notes of $2,000 in original principal amount or less shall be redeemed in part. Notwithstanding anything to the contrary stated herein, to the extent any such Notes are held in the form of Global Notes, the Notes to be redeemed shall be selected in accordance with the applicable procedures and requirements of DTC.

SECTION 3.3. Notice of Redemption. The Issuer shall mail or cause to be mailed (in each case sent by first class mail) in accordance with Section 12.1 and, in the case of Global Notes given in accordance with DTC procedures, a notice of redemption (other than a Special Mandatory Redemption) pursuant to Section 3.7 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) (which, in the case of a redemption subject to conditions, may be subject to extension of not more than three months until such conditions are satisfied).

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);

59

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

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

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

SECTION 3.4. Effect of Notice of Redemption. 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 Issuer’s discretion, be subject to the satisfaction or waiver of one or more conditions precedent, including completion of an Equity Offering, financing transaction, change of control 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 Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied or waived (but not more than three months until such conditions are 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 Issuer 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.

60

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

If the Issuer 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, 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 Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal from the redemption 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 Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

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 November 15, 2024 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium 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).

(b) On or after November 15, 2024, the Issuer may, on any one or more occasions, redeem all or a part of the Notes at the following redemption prices (expressed as percentages of the principal amount of the Notes to be redeemed) plus accrued and unpaid interest, if any, on the Notes redeemed to, but excluding, the applicable redemption date, if redeemed during the 12-month period beginning on November 15 of the years indicated below (subject to the rights of Holders of Notes on the relevant regular record date to receive interest due on the relevant interest payment date that is on or prior to the applicable redemption date):

61

(c) In the event that before November 15, 2024, the Issuer receives net cash proceeds from one or more Equity Offerings, the Issuer may use an amount not greater than the amount of such net cash proceeds to redeem up to 40.0% of the original aggregate principal amount of all Notes issued (calculated after giving effect to any issuance of Additional Notes) at a redemption price of 104.125% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date (subject to the rights of Holders of Notes on the relevant regular record date to receive interest due on the relevant interest payment date that is on or prior to the applicable redemption date); provided that:

(1) at least 50.0% of the aggregate principal amount of all Notes issued on the Issue Date remains outstanding after each such redemption; and

(2) the redemption date is within 120 days of the consummation of any such Equity Offering.

(d) If Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in connection with any tender offer or other offer to purchase the Notes (including pursuant to a Change of Control Offer, Alternate Offer or an offer to purchase with the proceeds from any Asset Disposition) and the Issuer, or any other Person making such offer in lieu of the Issuer, purchases all of the Notes validly tendered and not validly withdrawn by such Holders, the Issuer will have the right, upon not less than ten nor more than 60 days’ prior notice, to redeem all Notes that remain outstanding following such purchase (and the Holders of such remaining Notes shall be deemed to have consented to surrender their Notes) at a redemption price in cash equal to the applicable price paid to holders in such purchase, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (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 redemption).

(e) Nothing in this Indenture shall limit the ability of the Issuer or its Affiliates to purchase or acquire Notes in open-market purchases, tender or exchange offers or other negotiated transactions or otherwise.

62

SECTION 3.8. Special Mandatory Redemption.

(a) If (i) the consummation of the Acquisition does not occur on or before December 31, 2021 (or such later date if the end date is extended pursuant to the terms of the Acquisition Agreement) (the “End Date”) or (ii) the Issuer delivers a notice to the Trustee stating it has determined that the consummation of the Acquisition will not occur on or before the End Date (the earlier of the date of delivery of such notice and the End Date, the “Acquisition Deadline”), the Issuer will be required to redeem all of the Notes issued on the Issue Date (the “Special Mandatory Redemption”). The Special Mandatory Redemption will be required to occur by a date no later than ten days after the Acquisition Deadline, upon three days’ notice (the “Special Mandatory Redemption Date”) and at a redemption price equal to 100% of aggregate principal amount of the Notes, plus accrued and unpaid interest on the Notes being redeemed, if any, to, but excluding, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”).

If funds sufficient to pay the Special Mandatory Redemption Price of the Notes to be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee or the Paying Agent on or before such Special Mandatory Redemption Date, then on and after such Special Mandatory Redemption Date, the aggregate principal amount of Notes being redeemed will cease to bear interest.

(b) Subject to Section 3.8(a) hereof, upon the occurrence of the closing of the Acquisition, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

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

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

(17) Debt Incurred on behalf of, or representing guarantees of Debt Incurred by, joint ventures; provided that the aggregate principal amount of Debt Incurred or guaranteed pursuant to this clause (17) does not exceed the greater of (x) $210.0 million and (y) 40.0% of Consolidated EBITDA of the Issuer and its Restricted Subsidiaries determined for the Reference Period most recently ended (it being understood that any Debt Incurred pursuant to this clause (17) shall cease to be deemed Incurred or outstanding for purposes of this clause (17) but shall be deemed Incurred as Ratio Debt from and after the first date on which the Issuer or such Restricted Subsidiary could have Incurred such Debt as Ratio Debt without reliance on this clause (17));

(18) Debt of a joint venture to the Issuer or a Restricted Subsidiary and to the other holders of Capital Stock of, or participants in, such joint venture, so long as the percentage of the aggregate amount of such Debt of such joint venture owed to such holders of its Capital Stock or participants of such joint venture does not exceed the percentage of the aggregate outstanding amount of the Capital Stock of such joint venture held by such holders or such participant’s participation in such joint venture;

(19) Debt in respect of letters of credit, bank Guarantees or similar instruments issued to support performance obligations and trade letters of credit (other than obligations in respect of other Debt) in the ordinary course of business and consistent with past practice or industry practices;

(21) in addition to the items referred to in clauses (1) through (20) above, Debt of the Issuer or any Restricted Subsidiary which, together with any other outstanding Debt Incurred pursuant to this clause (21), and including any renewals, extensions, substitutions, refinancings or replacements of such Debt, has an aggregate principal amount at any one time outstanding, not to exceed the greater of (x) $300.0 million and (y) 45.0% of Consolidated EBITDA of the Issuer and its Restricted Subsidiaries determined for the Reference Period most recently ended determined at the time of Incurrence (it being understood that any Debt Incurred pursuant to this clause (21) shall be deemed Incurred or outstanding for purposes of this clause (21) but shall be deemed Incurred as Ratio Debt from and after the first date on which the Issuer or such Restricted Subsidiary could have Incurred such Debt as Ratio Debt without reliance on this clause (21)).

(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:

(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 Issuer, 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 Section 4.9 and shall only be required to include the amount and type of such Debt in one of such clauses; provided that all Debt outstanding on or prior to the Acquisition Closing Date (a) under the Term Loan Credit Agreement shall be deemed Incurred under subclause (i) of Section 4.9(b)(1) and may not later be reclassified and (b) under the ABL Credit Agreement shall be deemed Incurred under subclause (ii) of Section 4.9(b)(1) and may not be later reclassified;

(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;

(3) the principal amount of any Redeemable Stock or Preferred Stock of the Issuer 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;

76

(4) Debt permitted by this Section 4.9 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;

(5) any Receivables Sale shall be the amount for which there is recourse to the seller;

(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) Debt, the proceeds of which are funded into an escrow account or trust or similar arrangement pending the satisfaction of one or more conditions, unless and until such proceeds are released to the Issuer or any Restricted Subsidiary will not constitute Debt.

(d) Accrual of interest, accrual of dividends, the accretion of accreted value, the payment of interest in the form of additional Debt and the payment of dividends in the form of additional shares of Preferred Stock or Redeemable 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 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-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated 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 unpaid accrued interest and the aggregate amount of premiums (including reasonable tender premiums) and underwriting discounts, defeasance costs and fees, discounts and expenses in connection therewith). Notwithstanding any other provision of this Section 4.9, the maximum amount of Debt that the Issuer 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 Issuer shall not, and shall not permit any Restricted Subsidiary to, make any Asset Disposition unless:

(1) the Issuer or such 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;

77

(2) at least 75% of the consideration for such Asset Disposition and all other Asset Dispositions since the Issue Date on a cumulative basis consists of:

(i) cash or Cash Equivalents;

(ii) the assumption, forgiveness or cancellation of Debt of the Issuer or such Restricted Subsidiary (other than Debt that is subordinated to the Notes or such Restricted Subsidiary’s Subsidiary Guarantee) relating to such assets and release from all liability on the Debt assumed, forgiven or cancelled;

(iii) Replacement Assets, which, if the assets or property Disposed of was Collateral, must constitute Collateral;

(iv) Designated Non-cash Consideration; or

(v) any combination of the foregoing; and

(3) to the extent that any consideration received by the Issuer (or such Restricted Subsidiary, as the case may be) in such Asset Disposition constitutes property or other assets that are of a type or class that constitutes Collateral, such property or other assets are added to the Collateral securing the Notes in the manner and to the extent required by this Indenture or any of the Security Documents with the Lien on such Collateral securing the Notes being of the same priority with respect to the Notes as the Lien on the property or assets disposed of in the Asset Disposition;

provided that the amount of any consideration received by the Issuer or such Restricted Subsidiary that is converted into cash or Cash Equivalents within 180 days of the closing of such Asset Disposition shall be deemed to be cash or Cash Equivalents for purposes of this Section 4.10(a) (to the extent of the cash received). The foregoing clauses (1) or (2) of this Section 4.10(a) shall not apply with respect to any condemnation, event of loss or other involuntary Asset Disposition.

(b) Within 365 days after the receipt of any Net Available Proceeds from an Asset Disposition, the Issuer (or the applicable Restricted Subsidiary, as the case may be) may apply an amount equal to the amount of such Net Available Proceeds at its option, in any combination of the following:

(1) to reduce obligations under Priority Lien Debt and, in the case of revolving loans, to correspondingly reduce commitments with respect thereto;

(2) to reduce obligations under (i) Parity Lien Debt of the Issuer or any Subsidiary Guarantor, including the Notes and, if the assets or property Disposed of in the Asset Disposition were not Collateral, Pari Passu Debt, and, in the case of revolving loans, to correspondingly reduce commitments with respect thereto (provided that, if the Issuer or any Subsidiary Guarantor shall so reduce such obligations other than the Notes, the Issuer will (A) equally and ratably reduce obligations under the Notes as provided under Section 3.7 or through open-market

78

purchases (to the extent such purchases are at or above 100.0% of the principal amount thereof) or (B) make an Offer to Purchase (in accordance with the procedures set forth in this Indenture) to all Holders to purchase at a purchase price equal to 100.0% of the principal amount thereof, plus accrued and unpaid interest on, the principal amount of Notes that would otherwise be redeemed under subclause (A) above) or (ii) if the assets or property Disposed of in the Asset Disposition were not Collateral, any Debt of any Restricted Subsidiary of the Issuer that is not a Subsidiary Guarantor, in each case, other than Debt owed to the Issuer or a Restricted Subsidiary of the Issuer (and, in the case of revolving loans, to correspondingly reduce commitments with respect thereto);

(3) to acquire Replacement Assets, which, if the assets or property Disposed of were Collateral, must constitute Collateral, or make capital expenditures; provided that the Issuer 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 in Section 4.10(c) below; or

(4) any combination of the foregoing.

(c) Any Net Available Proceeds amounts 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 $50.0 million, or earlier, at the Issuer’s election, the Issuer will apply the Excess Proceeds to the repayment of the Notes and, if required by the terms of any Parity Lien Debt, and if the assets or property Disposed of in the Asset Disposition was not Collateral, if required by the terms of any Pari Passu Debt, as follows:

(1) the Issuer 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 Parity Lien Debt or Pari Passu Debt, as applicable (subject to proration in the event such amount is less than the aggregate Offered Price for all Notes tendered); and

(2) to the extent required by such Parity Lien Debt or Pari Passu Debt, the Issuer will make an offer to purchase or otherwise repurchase or redeem Parity Lien Debt (a “Parity Lien Offer”) or Pari Passu Debt (a “Pari Passu Offer”), as applicable, in an amount (the “Parity Lien Debt Amount” or “Pari Passu Debt

79

Amount,” as the case may be) equal to the excess of the Excess Proceeds over the Note Amount. However, in no event will the Issuer be required to make a Parity Lien Offer or Pari Passu Offer in a Parity Lien Debt Amount or Pari Passu Debt Amount, as applicable, exceeding the principal amount of such Parity Lien Debt or Pari Passu Debt plus the amount of any premium required to be paid to repurchase such Parity Lien Debt or Pari Passu Debt, as applicable.

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 excluding, 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 Parity Lien Debt or Pari Passu Debt that is purchased in a Parity Lien Offer or Pari Passu Offer, as applicable, is less than the Parity Lien Debt Amount or Pari Passu Debt Amount, as applicable, the Issuer may use any remaining Excess Proceeds for any purpose and the amount of Excess Proceeds under this Indenture will be deemed zero. If the aggregate principal amount of Notes and Parity Lien Debt or Pari Passu Debt, as applicable, surrendered by holders thereof exceeds the amount of Excess Proceeds, the selection of the Notes and Parity Lien Debt or Pari Passu Debt, as applicable, to be purchased shall be designated in writing by the Issuer to the Trustee on a pro rata basis to the extent practicable, by lot or by such other method as the Trustee shall deem fair and appropriate; 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 applicable Depositary; otherwise, such beneficial interests shall be selected for repurchase in accordance with such procedures. Upon the completion of the purchase of all the Notes tendered pursuant to an Offer to Purchase and the completion of a Parity Lien Offer or Pari Passu Offer, as applicable, 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 Issuer 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 Parity Lien Debt or Pari Passu Debt, as applicable, shall be purchased by the Issuer, 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 such Holders, or such later date as may be necessary for the Issuer to comply with the requirements under the Exchange Act.

(e) Notwithstanding anything to the contrary set forth herein, to the extent that repatriation to the United States of any or all of the Net Available Proceeds of any Asset Disposition by a Foreign Subsidiary (x) is prohibited or delayed by applicable local law or (y) would result in material adverse tax consequences (taking into account any foreign tax credit or other net benefit actually realized in connection with such repatriation that would not otherwise be realized), as determined by the Issuer in its sole discretion, the portion of

80

such Net Available Proceeds so affected will not be required to be applied in compliance with this Section 4.10, and such amounts may be retained by the applicable Foreign Subsidiary; provided that clause (x) of this Section 4.10(e) shall apply to such amounts for so long, but only for so long, as the applicable local law will not permit repatriation to the United States (the Issuer hereby agreeing to use commercially reasonable efforts to cause the applicable Foreign Subsidiary to take all actions reasonably required by the applicable local law, applicable organizational impediments or other impediment to permit such repatriation), and if such repatriation of any of such affected Net Available Proceeds is permitted under the applicable local law and is not subject to clause (y) of this Section 4.10(e), then such repatriation will be promptly effected and such repatriated Net Available Proceeds will be applied (net of additional taxes payable or reserved against as a result thereof) in compliance with this Section 4.10. The time periods set forth in this Section 4.10 shall not start until such time as the Net Available Proceeds may be repatriated (whether or not such repatriation actually occurs).

(f) The Issuer shall comply with all applicable securities laws and regulations in the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable securities 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 Issuer shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

(g) The Issuer and the Guarantors will not enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Debt of any other Person, other than as permitted by this Indenture, the Notes and the Security Documents.

SECTION 4.11. Limitation on Transactions with Affiliates.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, enter into any transaction or series of related transactions having a value in excess of $5.0 million with or for the benefit of an Affiliate of the Issuer or a Restricted Subsidiary, including any Investment, either directly or indirectly, unless such transaction is on terms no less favorable to the Issuer 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 or is otherwise fair to the Issuer from a financial point of view. For any transaction or series of related transactions involving aggregate value in excess of $50.0 million, such transaction or series of related transactions is approved by either (x) a majority of the Disinterested Directors of the Board of Directors of the Issuer or any Parent Company, if any, or in the event there is only one Disinterested Director, by such Disinterested Director, or (y) the audit committee of the Board of Directors of the Issuer or any Parent Company (with any Director on such committee that is not a Disinterested Director recusing himself or herself).

81

(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 Board of Directors or senior management of the Issuer, when taken as a whole, than the terms of the agreements in effect on the Issue Date;

(2) any employment agreement, employee benefit arrangements or severance arrangements with any officer, director or employee, including under any stock option or stock incentive plans, entered into by the Issuer or any of its Restricted Subsidiaries in the ordinary course of business of the Issuer or such Restricted Subsidiary or approved by a majority of the disinterested members of the Board of Directors;

(3) transactions between or among Holdings, the Issuer and/or its Restricted Subsidiaries and any Guarantees issued by any Parent Company, the Issuer, Ultimate Parent or a Restricted Subsidiary for the benefit of the Issuer or a Restricted Subsidiary, as the case may be, in accordance with Section 4.9;

(4) any transaction with any Person (x) that is not an Affiliate of the Issuer immediately before the consummation of such transaction that becomes an Affiliate of the Issuer as a result of such transaction or (y) that is an Affiliate of the Issuer solely because the Issuer, directly or indirectly, owns Capital Stock in, or controls, such Person;

(5) transactions with joint ventures entered into in the ordinary course of business; provided that no other Affiliate of the Issuer (other than a Subsidiary thereof) directly or indirectly holds any Capital Stock of such joint venture;

(6) payment of reasonable directors fees to Persons who are not otherwise employees of the Issuer;

(7) indemnities of officers, directors and employees of Holdings, the Issuer or a Restricted Subsidiary (and, to the extent directly attributable to the operations of the Issuer and the other Restricted Subsidiaries, to any other Parent Company) pursuant to bylaws, or statutory provisions or indemnification agreements or the purchase of indemnification insurance for any director or officer;

(8) any Restricted Payment or Permitted Investment that is permitted to be made pursuant to Section 4.7;

(9) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of the business of Holdings, the Issuer and its Restricted Subsidiaries and otherwise in compliance with the terms of this Indenture; provided that, in the reasonable determination of the Issuer, such transactions are on terms that are no less favorable to the Issuer or the relevant Restricted Subsidiary than those that could have been obtained at the time of such transactions in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person;

82

(10) the grant, issuance or sale of Capital Stock (other than Redeemable Stock) to Affiliates of the Issuer and the granting of registration rights and other customary rights in connection therewith;

(11) any transaction as to which the Issuer 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 transaction or series of related transactions is fair to the Issuer or such Restricted Subsidiary from a financial point of view or stating that the terms are no less favorable to the Issuer 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;

(12) any written agreement entered into or assumed in connection with mergers or acquisitions of other businesses with Persons who were not Affiliates prior to such transactions; provided that such agreement was not entered into in contemplation of such merger or acquisition, and any amendment thereto, so long as any such amendment is not disadvantageous to the Holders in the good faith judgment of the Board of Directors or senior management of the Issuer, when taken as a whole, as compared to the applicable agreement as in effect on the date of such acquisition or merger;

(13) the entering into of any tax sharing agreement or arrangement or any tax receivable agreement with Ultimate Parent or any Parent Company, or any transactions pursuant to any such agreement including the Tax Receivable Agreement; and

(14) transactions relating to the reimbursement of the Sponsor or Affiliates of the Sponsor for reasonable out-of-pocket expenses and indemnification pursuant to the terms of the Advisory Agreement.

SECTION 4.12. Limitation on Liens.

(a) The Issuer 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 assets (real or personal, tangible or intangible) of the Issuer or such Restricted Subsidiary.

(b) If the Issuer or any Restricted Subsidiary (including any Subsidiary Guarantor) creates any Lien upon any property or assets to secure any Parity Lien Debt or Priority Lien Debt, it must concurrently grant a first-priority Lien (subject to Permitted Liens) upon such property or assets that would constitute Fixed Asset Collateral or a second-priority Lien (subject to Permitted Liens) upon such property or assets that would constitute Current Asset Collateral (other than Foreign Collateral) as security for the Notes or the applicable Subsidiary Guarantee such that the property or assets (other than Foreign Collateral) subject to such Lien will constitute Collateral under this Indenture and the Security Documents.

83

(c) Any Lien that is granted to secure the Notes or the applicable Subsidiary Guarantee pursuant to the preceding paragraph shall be automatically and unconditionally released and discharged at the same time as the release of the Lien that gave rise to the obligation to secure the Notes or the Subsidiary Guarantee under the preceding paragraph (other than a release as a result of the enforcement of remedies in respect of such Lien or the obligations secured by such Lien).

(d) With respect to any Lien securing Debt that was permitted to secure such Debt at the time of the Incurrence of such Debt, such Lien shall also be permitted to secure any Increased Amount of such Debt. The “Increased Amount” of any Debt means any increase in the amount of such Debt in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Debt with the same terms, accretion of original issue discount or liquidation preference, any fees, underwriting discounts, accrued and unpaid interest, premiums and other costs and expenses incurred in connection therewith and increases in the amount of Debt outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Debt.

SECTION 4.13. Offer to Purchase upon Change of Control. No later than 30 days after the occurrence of a Change of Control, the Issuer will be required to make an Offer to Purchase (a “Change of Control Offer”), with a copy to the Trustee, all outstanding Notes at a purchase price equal to 101% of their principal amount plus accrued and unpaid interest, if any, to, but excluding, the purchase date (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 Issuer will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of the Notes or portions of Notes properly tendered.

On the Purchase Date, the Issuer 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 Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

84

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

If the 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 Issuer 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 Issuer 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, 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 Issuer 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.

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, and conditioned upon the occurrence of a Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer or Alternate Offer.

The Issuer shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to an Offer to Purchase the Notes. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.13, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.13 by virtue of the conflict.

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

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

85

SECTION 4.15. Future Guarantees.

(a) If any Domestic Subsidiary that is not already a Subsidiary Guarantor guarantees any Debt of the Issuer or a Subsidiary Guarantor under, or borrows Debt under, the Senior Credit Facilities on or after the Issue Date, then such Domestic 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 Domestic 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 this Indenture.

(b) Each Person that becomes a Subsidiary Guarantor after the Issue Date shall also become a party to the applicable Security Documents and shall as promptly as practicable execute and deliver such security instruments, financing statements, mortgages, deeds of trust (in substantially the same form as those executed and delivered with respect to the Collateral on the Issue Date or on the date first delivered in the case of Collateral which this Indenture provides may be delivered after the Issue Date (but no greater scope)) as may be necessary to vest in the Collateral Agent a perfected first-priority security interest (subject to Permitted Liens) in properties and assets that constitute Fixed Asset Collateral and a perfected second-priority security interest (subject to Permitted Liens) in properties and assets that constitute Current Asset Collateral, in either case, as security for such Subsidiary Guarantor’s Subsidiary Guarantee and as may be necessary to have such property or asset added to the Collateral as required under the Security Documents and this Indenture, and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such properties and assets to the same extent and with the same force and effect.

SECTION 4.16. Designation of Restricted and Unrestricted Subsidiaries.

(a) The Issuer, by delivery of an Officers’ Certificate to the Trustee, 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 Issuer 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 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 Issuer 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, except, in either case, to the extent that the amount of any such Debt constitutes a Restricted Payment or Permitted Investment that is made in compliance with Section 4.7; (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 Issuer 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; (4) such Subsidiary is a Person with

86

respect to which neither the Issuer nor any of its Restricted Subsidiaries has any direct or indirect obligation to (a) subscribe for additional Capital Stock of such Subsidiary or (b) maintain or preserve such Subsidiary’s financial condition or to cause such Subsidiary to achieve any specified levels of operating results, except in either case to the extent that the amount of any such obligation constitutes a Restricted Payment or Permitted Investment that is made in compliance with Section 4.7; and (5) no Default shall have occurred and be continuing at the time of, or immediately after giving effect to, such designation. The designation of any Restricted Subsidiary as an Unrestricted Subsidiary shall constitute an Investment by the Issuer in such Subsidiary on the date of designation in an amount equal to the Fair Market Value of the Issuer’s Investment therein.

(b) The Issuer, by delivery of an Officers’ Certificate to the Trustee, may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Issuer if: (1)(x) the Issuer would be able to Incur at least $1.00 of additional Debt pursuant to Section 4.9(a), or (y) the Fixed Charge Coverage Ratio of the Issuer would not be less than the Fixed Charge Coverage Ratio of the Issuer immediately prior to such designation, in each case on a Pro Forma Basis taking into account 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. The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute the incurrence at the time of designation of any Investment, Debt or Liens of such Subsidiary existing at such time.

SECTION 4.17. Covenant Suspension.

(a) If on any date following the Issue Date (i) the Notes have an Investment Grade Rating from two Rating Agencies and (ii) no Default or Event of Default has occurred and is then continuing, then, upon delivery by the Issuer to the Trustee of an Officers’ Certificate to the foregoing effect, the Issuer and the Restricted Subsidiaries will no longer be subject to the following covenants:

(1) Section 4.7;

(2) Section 4.8

(3) Section 4.9;

(4) Section 4.10, but only to the extent related to properties or assets of the Issuer or its Restricted Subsidiaries that do not constitute Collateral;

(5) Section 4.11

(6) Section 4.15, but only with respect to any Person that is required to become a Subsidiary Guarantor after the date of the occurrence of the covenant suspension; and

(7) Section 5.1(a)(3).

87

During any period that the foregoing covenants have been suspended, the Issuer shall not designate any of the Issuer’s Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.16 unless such designation would have complied with Section 4.7 as if such covenant were in effect during such period.

Upon the occurrence of a covenant suspension, the amount of Excess Proceeds from Net Available Proceeds shall be reset at zero. During any period that the foregoing covenants have been suspended, any reference in the definition of “Unrestricted Subsidiary” or “Permitted Liens” to Section 4.9 or any provision thereof shall be construed as if such covenant had remained in effect since the Issue Date and during such period.

(b) Notwithstanding the foregoing, if the Notes cease to have an Investment Grade Rating from two Rating Agencies, the foregoing covenants will be reinstated as of and from the date of such rating decline, subject to further suspension in the future upon the satisfaction of the conditions described in Section 4.17(a) above. Any Debt Incurred during a period when the covenants are suspended (a “suspension period”) will be classified as having been Incurred pursuant to Section 4.9(a). 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 clause (2) of Section 4.9(b). Calculations under the reinstated Section 4.7 will be made as if Section 4.7 had been in effect prior to, but not during, a suspension period. In addition: (i) for purposes of Section 4.8, all contracts entered into during a suspension period that contain any of the restrictions contemplated by such covenant will be deemed to have been entered into pursuant to clause (1) of Section 4.8(b); and (ii) for purposes of Section 4.11, all agreements and arrangements entered into by the Issuer or any Restricted Subsidiary with an Affiliate of the Issuer during a suspension period will be deemed to have been entered into pursuant to clause (1) of Section 4.11(b). 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 Issuer or its Restricted Subsidiaries during a suspension period, and the Issuer and any Subsidiary of the Issuer will be permitted, without causing a Default or Event of Default or breach of any of the suspended covenants (notwithstanding the reinstatement thereof) under this Indenture, to honor, comply with or otherwise perform any contractual commitments or obligations entered into during a suspension period following a downgrade and to consummate the Transactions.

(c) Promptly following the occurrence of any suspension or reinstatement of the covenants as described above, the Issuer shall provide an Officers’ Certificate to the Trustee regarding such occurrence. The Trustee shall have no obligation to monitor the ratings of the Notes or 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 Officers’ Certificate to any Holder of the Notes upon written request.

SECTION 4.18. Use of Proceeds Prior to the Consummation of the Acquisition. Prior to the earlier of (i) the date of the consummation of the Acquisition and (ii) the date on which the Notes are redeemed by the Issuer pursuant to Section 3.8, the Issuer will not, and will not permit any of its Subsidiaries to, use the net proceeds from the issuance of the Notes for any other purpose other than making investments in Cash Equivalents or consummating the Acquisition. Upon the consummation of the Acquisition, this Section 4.18 will automatically cease to be of any force or effect.

88

SECTION 4.19. Limited Activities. Holdings will not engage in any business other than its ownership of the capital stock of, and the management of, the Issuer and, indirectly, its Subsidiaries and activities incidental thereto; provided that Holdings may engage in those activities that are incidental to:

(a) the maintenance of its existence in compliance with applicable law;

(b) legal, tax and accounting matters in connection with any of the foregoing or following activities;

(c) the entering into, and performing its obligations under, this Indenture, the other Security Documents to which it is a party, the Advisory Agreement, the Term Loan Credit Agreement, the ABL Credit Agreement and the other definitive documentation entered into in connection therewith;

(d) the issuance, sale or repurchase of its Equity Interests and the receipt of capital contributions;

(e) the making of dividends or distributions on its Equity Interests;

(f) the filing of registration statements, and compliance with applicable reporting and other obligations, under federal, state or other securities laws;

(g) the listing of its equity securities and compliance with applicable reporting and other obligations in connection therewith;

(h) the retention of (and the entry into, and exercise of rights and performance of obligations in respect of, contracts and agreements with) transfer agents, private placement agents, underwriters, counsel, accountants and other advisors and consultants;

(i) the performance of obligations under and compliance with its certificate of incorporation and by-laws, or any applicable law, ordinance, regulation, rule, order, judgment, decree or permit, including, without limitation, as a result of or in connection with the activities of its Subsidiaries;

(j) the incurrence and payment of its operating and business expenses and any taxes for which it may be liable (including reimbursement to Affiliates for such expenses paid on its behalf);

(k) the consummation of the Transactions;

(l) the making of loans to or other Investments in, or incurrence of Debt from, the Issuer (or in the case of incurrence of Debt, from any Wholly Owned Restricted Subsidiary which is a Subsidiary Guarantor) as and to the extent not prohibited by this Indenture; and

(m) any other activity expressly contemplated by this Indenture to be engaged in by Holdings, including, without limitation, repurchases of Debt of the Issuer under this Indenture and entry into and performance of guarantees of Permitted Debt and, subject to any applicable limitations set forth herein, other Permitted Debt of the Issuer and its Restricted Subsidiaries.

(3) except in the case of any such consolidation or merger of the Issuer 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 Issuer or a Restricted Subsidiary as a result of such transaction as having been Incurred by the Issuer or such Restricted Subsidiary at the time of the transaction, either (i) the Issuer (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 Fixed Charge Coverage Ratio of the Issuer or such Successor Company immediately after such transaction is not less than it was immediately before such transaction;

(8) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture, if any, do not violate this Indenture.

Notwithstanding the foregoing, (i) any Restricted Subsidiary may merge into the Issuer or another Restricted Subsidiary, (ii) the provisions of clauses (2) or (3) above shall not apply to a merger of the Issuer with or into a Restricted Subsidiary and (iii) the above provisions shall not apply to any transfer of assets between or among the Issuer and any Restricted Subsidiary.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Issuer under this Indenture, and, except in the case of a lease of all or substantially all its assets, the Issuer will be released from the obligation to pay the principal of, and interest on, the Notes and all other obligations under this Indenture.

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

(5) default under the terms of any instrument evidencing or securing any Debt of Holdings, the Issuer or any Restricted Subsidiary having an outstanding principal amount of $100.0 million, individually or in the aggregate, which default results in the acceleration of the payment of all or any portion of such Debt or constitutes the failure to pay all or any portion of the principal amount of such Debt when due at final maturity (after giving effect to any applicable grace period provided in such Debt) and if, within 30 days of such payment default or acceleration, such Debt has not been discharged or such payment default has not been cured or such acceleration has not been rescinded or annulled; provided that in connection with any series of convertible or exchangeable securities (a) any conversion or exchange of such securities by a holder thereof into shares of Capital Stock, cash or a combination of cash and shares of Capital Stock, (b) the rights of holders of such securities to convert or exchange into shares of Capital Stock, cash or a combination of cash and shares of Capital Stock and (c) the rights of holders of such securities to require any repurchase by the Issuer of such securities in cash shall not, in itself, constitute an Event of Default under this clause (5);

93

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

(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;

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

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

94

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

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

(9) the Guarantee of any Guarantor 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 Guarantor or any Person acting on behalf of any Guarantor denies or disaffirms such Guarantor’s obligations under its Guarantee (other than by reason of a release of such Guarantor from its Guarantee in accordance with the terms of this Indenture);

(10) (x) any material provision of any Security Document, at any time, (a) ceases to be in full force and effect for any reason other than in accordance with the terms of this Indenture and the Security Documents, or (b) is declared invalid or unenforceable by a court of competent jurisdiction, (y) the Issuer or any Guarantor contests in writing the validity or enforceability of any provision of any Security Document or (z) the Issuer or any Guarantor denies in writing that it has any further liability under this Indenture, any Security Document or gives written notice to revoke or rescind any Security Document or the perfected first-priority or second-priority, as applicable, Liens created thereby other than in accordance with the terms of this Indenture and the Security Documents; and

(11) any Security Document covering a material portion of the Collateral for any reason (other than pursuant to the terms thereof) ceases to create a valid and perfected first-priority or second-priority, as applicable, Lien on and security interest in any material Collateral covered thereby, subject to Permitted Liens, except (a) to the extent that any such perfection or priority is not required pursuant to this Indenture and the Security Documents or results from the failure of the Collateral Agent to maintain possession of certificates actually delivered to it representing securities pledged under the Security Documents or (b) as to Collateral consisting of Real Property, to the extent that such losses are covered by a title insurance policy in favor of the Collateral Agent for its benefit and the benefit of the other Secured Parties and such insurers have not denied or failed to acknowledge coverage.

Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more Holders (each a “Directing Holder”) must be accompanied by a written representation from each such Holder delivered to the Issuer and the Trustee that such Holder is not (or, in the case such Holder is DTC or its nominee, that such Holder is being instructed solely

95

by beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such Holder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”). The Trustee shall have no duty whatsoever to obtain for, or provide such other information to, the Issuer. In any case in which the Holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its notice or instruction to the Trustee.

If, following the delivery of an Officers’ Certificate, but prior to acceleration of the Notes, the Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officers’ Certificate stating that the Issuer has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such Default or Event of Default shall be automatically stayed and the cure period with respect to such Default or Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter. If, following the delivery of an Officers’ Certificate, but prior to acceleration of the Notes, the Issuer provides to the Trustee an Officers’ Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default or Event of Default shall be automatically stayed and the cure period with respect to any such Default or Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Default or Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, such voiding of such Noteholder Direction shall not void or invalidate any indemnity or security provided by the Directing Holders to the Trustee, which such indemnification or security obligations shall continue to survive.

Notwithstanding anything in the preceding two paragraphs to the contrary, any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy or similar proceeding shall not require compliance with the foregoing paragraphs.

96

For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, and shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any Officers’ Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no liability to the Issuer, any Holder or any other Person in acting in good faith on a Noteholder Direction, or on any Officers’ Certificate with respect to a Noteholder Direction or Verification Covenant, and the Issuer, any Holder or any such other Person waives any and all claims, in law and/or in equity, against the Trustee and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes with respect to, a Noteholder Direction or Verification Covenant or any Officers’ Certificate with respect to a Noteholder Direction or Verification Covenant or in accordance with the foregoing paragraphs. The Issuer hereby confirms that any and all actions that the Trustee takes or omits to take under this Section 6.1 and all fees, costs and expenses of the Trustee and its agents and counsel arising hereunder and in connection herewith shall be covered by the Issuer’s indemnification under Section 7.6 hereof.

SECTION 6.2. Acceleration. If an Event of Default (other than an Event of Default specified in clause (7) or (8) of Section 6.1) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) the principal of, and accrued and unpaid interest, if any, on all outstanding amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest, if any, on 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 all Events of Default, other than an Event of Default specified in clause (1) of Section 6.1, have been cured or waived, and:

(1) the rescission would not conflict with any judgment or decree; and

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

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

If an Event of Default specified in clause (7) or (8) of Section 6.1 occurs, then all unpaid principal of, and accrued and unpaid interest, if any, on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or other action or notice on the part of the Trustee or any Holder of the Notes 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.

97

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

SECTION 6.4. Waiver of Past Defaults. Subject to Section 9.2, the Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest or premium 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 power conferred on it. However, (i) the Trustee may require 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 (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such direction is unduly prejudicial to the rights of such other Holders) 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 thereunder (subject to the Intercreditor Agreements) 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. However, such limitations do not apply to a suit instituted by a Holder of a Note for the enforcement of payment of the principal of or any premium or interest on such Note on or after the applicable due date specified in such Note.

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

SECTION 6.7. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, premium or 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.

98

SECTION 6.8. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.1 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium, 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 Issuer (or any other obligor upon the Notes including Holdings and 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 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 or otherwise holds any money or property pursuant to this Article VI, it shall, subject to the terms of the Intercreditor Agreements, pay out the money and property in the following order:

First: to the Trustee and the Collateral Agent, and their respective 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;

99

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

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

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

SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as the Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by Holders of more than 10.0% in principal amount of the then-outstanding Notes.

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 Issuer, 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.

103

SECTION 7.3. Individual Rights of the Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.9.

SECTION 7.4. Disclaimer. Neither the Trustee nor the Collateral Agent shall be responsible for and none of them makes any representation as to the validity or adequacy of this Indenture, the Notes, any Guarantee or the Security Documents. Neither the Trustee nor the Collateral Agent shall be accountable for the use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture. Neither the Trustee nor the Collateral Agent shall be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and neither shall be responsible for any statement or recital herein or any statement in the Notes, any Officers’ Certificate delivered to the Trustee or the Collateral Agent 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 clause (j) of Section 7.2, 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 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 Issuer shall pay to the Trustee and the Collateral Agent from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee and the Collateral Agent, 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 each of the Trustee’s and the Collateral Agent’s agents and counsel.

Each of Holdings, the Issuer and the Subsidiary Guarantors, jointly and severally, shall indemnify, defend, protect and hold the Trustee and the Collateral Agent (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 and the Security Documents, the performance of its obligations and/or exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture and the Security Documents against Holdings, the Issuer or any Subsidiary Guarantor (including this Section 7.6) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall have been found by a court of competent

104

jurisdiction in a non-appealable final decision to have been caused by its own gross negligence or willful misconduct. The Trustee and the Collateral Agent shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee and the Collateral Agent to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee and the Collateral Agent may each have one separate counsel, and the Issuer shall pay the reasonable fees and expenses of such counsel for the Trustee and the Collateral Agent. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

The obligations of Holdings, the Issuer 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 and/or the Collateral Agent.

To secure the Issuer’s payment obligations in this Section 7.6, the Trustee and the Collateral Agent shall have a Lien prior to the Notes on all money or property held or collected by the Trustee and the Collateral Agent, 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 and the Collateral Agent.

When the Trustee and the Collateral Agent incurs expenses or renders services after an Event of Default specified in clause (7) of Section 6.1 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 Code.

SECTION 7.7. Replacement of Trustee or Collateral Agent. A resignation or removal of the Trustee or the Collateral Agent and appointment of a successor Trustee or Collateral Agent shall become effective only upon the successor trustee’s or successor collateral agent’s, as applicable, acceptance of appointment as provided in this Section 7.7.

The Trustee or Collateral Agent may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then-outstanding Notes may remove the Trustee or the Collateral Agent upon 30 days’ written notice to the Trustee or the Collateral Agent, as applicable, and the Issuer. The Issuer may remove the Trustee or the Collateral if no Event of Default exists and:

(a) the Trustee or the Collateral Agent, as applicable, is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Code;

(b) a custodian or public officer takes charge of the Trustee or the Collateral Agent, as applicable, or its property; or

(c) the Trustee or the Collateral Agent becomes incapable of acting.

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

105

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

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 or successor collateral agent, as the case may be, shall deliver a written acceptance of its appointment to the retiring Trustee or retiring Collateral Agent, as applicable, and to the Issuer. Thereupon, the resignation or removal of the retiring Trustee or successor collateral agent, as the case may be, shall become effective, and the successor trustee or successor collateral agent, as the case may be, shall have all the rights, powers and the duties of the Trustee or Collateral Agent, as applicable, under this Indenture. The successor trustee or successor collateral agent, as the case may be, shall mail a notice of its succession to the Holders. The retiring Trustee or retiring Collateral Agent, as applicable, shall promptly transfer all property held by it as Trustee or Collateral Agent to the successor Trustee or successor collateral agent, as the case may be,; provided that all sums owing to such Trustee or Collateral Agent hereunder have been paid and subject to the Lien provided for in Section 7.6. Notwithstanding replacement of the Trustee or the Collateral Agent pursuant to this Section 7.7, Holdings’, the Issuer’s and the Subsidiary Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee or retiring Collateral Agent, as applicable.

SECTION 7.8. Successor by Merger, Etc. If the Trustee, the Collateral Agent or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee, successor Collateral Agent or successor 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.

Anything in this Article VIII to the contrary notwithstanding, the Deposit Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any U.S. dollars or non-callable U.S. Government Obligations held by it as provided in Section 8.4 or Section 8.8 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Deposit Trustee (which may be the opinion delivered under clause (1) of Section 8.4), 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 Issuer, 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

109

the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease.

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 Holdings, the Issuer 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 Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

SECTION 8.8. Discharge. This Indenture and the Security Documents will be discharged and will cease to be of further effect and any Collateral then securing the Notes shall be automatically released (except as to surviving rights or 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 and the Collateral Agent) as to all outstanding Notes and all Guarantees when either:

(1) (a) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation; or (b) 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 within one year under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Issuer, and, in any case, the Issuer or any 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, 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;

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

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

110

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

After the Notes are no longer outstanding, the Issuer’s and the Guarantors’ obligations in Section 7.6, 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 Officers’ Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

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

(a) 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), Holdings, the Issuer, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture, the Notes, any Guarantees or the Security Documents (including in each case, if applicable, the form of agreements attached thereto as exhibits) or waive any existing Default or Event of Default or compliance with any provision of this Indenture, the Notes or the Security Documents; provided, however, that no such modification or amendment 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;

(3) change the place or currency of payment of principal of (or premium), or interest on, any Note;

113

(4) (i) modify, in any manner adverse to the Holders of the Notes, the right to institute suit for the enforcement of any payment of principal of (or premium), or interest on, or with respect to, any Note when due, or (ii) 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;

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.

114

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

SECTION 9.4. 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 Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

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

SECTION 9.5. Trustee and Collateral Agent to Sign Amendments, Etc. The Trustee and the Collateral Agent, as applicable, 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 or the Collateral Agent, as applicable. In signing or refusing to sign any amendment or supplemental indenture, the Trustee or the Collateral Agent, as applicable, shall be provided with and (subject to Section 7.1) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture or the Security Documents, as applicable, and that all conditions precedent thereto have been met or waived; provided that no such Opinion of Counsel shall be required to be delivered in connection with the execution of any amendment or supplement entered into in connection with adding or releasing a Guarantor pursuant to the terms of this Indenture and the Security Documents.

GUARANTEES

SECTION 10.1. Guarantees.

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

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

115

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby agrees that, in the event of a Default in payment of principal or premium, if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under this Indenture.

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

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

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

116

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

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

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

SECTION 10.4. Limitation of Guarantors’ Liability. Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference or fraudulent transfer or otherwise reviewable under applicable law.

SECTION 10.5. Releases. A Subsidiary 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 after giving effect to such transaction) the Issuer or a Restricted Subsidiary of the Issuer, 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 Issuer or a Restricted Subsidiary of the Issuer, if after such sale, transfer or disposition, such Subsidiary Guarantor would cease to be a Restricted Subsidiary and all pledges and security interests granted in connection with any Debt and the sale or other disposition does not violate Section 4.10 of this Indenture;

117

(c) the exercise by the Issuer 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 Issuer as an Unrestricted Subsidiary in accordance with the terms of this Indenture; or

(e) the Subsidiary Guarantor ceasing to guarantee any Debt of the Issuer or a Subsidiary Guarantor under, or be a borrower under, the Term Loan Credit Agreement and no Event of Default has occurred and is continuing.

The Guarantee of Holdings will be released upon the exercise by the Issuer 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.

Upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that all conditions precedent to the release of a Subsidiary Guarantor’s Subsidiary Guarantee set forth in this Indenture have been satisfied, the Trustee shall execute, without representation or warranty, any documents reasonably requested by the Issuer in writing in order to evidence the release of any Subsidiary Guarantor from its obligations under its Subsidiary Guarantee.

Any Subsidiary Guarantor not released from its obligations under its Subsidiary 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 Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

ARTICLE XI

COLLATERAL AND SECURITY

SECTION 11.1. Collateral.

(a) The due and punctual payment of the principal of, premium, if any, and interest on the Notes and the Guarantees when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, interest on the overdue principal of and interest (to the extent permitted by law), if any, on the Notes and the Guarantees and performance of all other obligations under this Indenture, including, without limitation, the obligations of the Issuer set forth in Section 7.6, and the Notes, the Guarantees and the Security Documents, shall be secured by a Lien on the Fixed Asset Collateral on a first-priority basis and secured by a Lien on the Current Asset Collateral on a second-priority basis, in each case subject to Permitted Liens, as provided in this Indenture and the Security Documents to which the Issuer and the Guarantors, as the case may be, shall be or shall have become parties to simultaneously with the execution of this Indenture and will be secured by all of the Collateral pledged pursuant to the Security Documents hereafter delivered as required or permitted by this Indenture and the Security Documents. The Issuer, for the benefit of the Holders,

118

hereby appoints UMB Bank, N.A., as the initial Collateral Agent and the Collateral Agent is hereby authorized and directed to execute and deliver the Security Documents. Each Holder by its acceptance of any Notes and the Guarantees thereof, irrevocably consents and agrees to such appointment. Notwithstanding any provision to the contrary contained elsewhere in this Indenture or the other Note Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other Note Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, the Issuer or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture or the other Note Documents, or otherwise exist, against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) Each Holder, by its acceptance of any Notes and the Guarantees, consents and agrees to the terms of the Security Documents (including, without limitation, the provisions providing for foreclosure and release of Collateral and the automatic amendments, supplements, consents, waivers and other modifications thereto without the consent of the Holders) as the same may be in effect or may be amended from time to time in accordance with their terms and this Indenture and authorizes and directs the Collateral Agent to execute and deliver the Security Documents, perform its obligations and exercise its rights under the Security Documents in accordance therewith.

(c) The Trustee and each Holder, by accepting the Notes and the Guarantees, acknowledge that, as more fully set forth in the Security Documents, the Collateral as now or hereafter constituted shall be held for the benefit of all the Secured Parties, and that the Lien of this Indenture and the Security Documents in respect of the Secured Parties is subject to and qualified and limited in all respects by the Security Documents and actions that may be taken thereunder.

SECTION 11.2. Maintenance of Collateral. The Issuer and the Guarantors shall maintain the Collateral in good, safe and insurable operating order, condition and repair (ordinary wear and tear excepted) and shall do all other acts as may be reasonably necessary or appropriate to maintain and preserve the Collateral, provided that the Issuer and the Guarantors shall pay all real estate and other taxes (except such as are being contested in good faith and by appropriate negotiations or proceedings), and maintain in full force and effect all material permits and certain insurance coverages.

119

SECTION 11.3. Impairment of Security Interest. Neither the Issuer nor any of its Restricted Subsidiaries will (i) take or knowingly or negligently omit to take any action which would materially adversely affect or impair the Liens in favor of the Collateral Agent and the Holders with respect to the Collateral unless such action or failure to take action is otherwise permitted by this Indenture or the Security Documents or (ii) grant any Person, or permit any Person to retain (other than the Collateral Agent), any Liens on the Collateral, other than Permitted Liens. The Issuer and each Guarantor will, at its sole cost and expense, execute, deliver and file all such agreements and instruments as necessary, or as the Trustee or the Collateral Agent reasonably requests, to more fully or accurately describe the assets and property intended to be Collateral or the obligations intended to be secured by the Security Documents.

SECTION 11.4. Further Assurances. To the extent required under this Indenture or any of the Security Documents, and subject to the Intercreditor Agreements, the Issuer and the Guarantors shall, at their sole expense, execute any and all further documents, financing statements, agreements and instruments, and take all further actions that may be required under applicable law, or that the Collateral Agent or the Trustee may reasonably request, in order to grant, preserve, protect and perfect the validity and priority of the security interests and Liens created or intended to be created by the Security Documents in the Collateral. In addition, to the extent required under this Indenture or any of the Security Documents, from time to time, the Issuer and the Guarantors will, at their sole expense, reasonably promptly secure the obligations under this Indenture and Security Documents by pledging or creating, or causing to be pledged or created, perfected security interests and Liens with respect to the Collateral to the extent required by this Indenture and/or the Security Documents.

SECTION 11.5. After-Acquired Property. (a) Upon the acquisition by any of the Issuer or the Guarantors after the Issue Date of any assets (including in connection with the consummation of the Acquisition) (other than Excluded Collateral and property subject to certain Permitted Liens), the Issuer or such Guarantor shall, at their sole expense, execute and deliver, subject to the Intercreditor Agreements, such amendments to the Security Documents or such other documents, agreements, security instruments and financing statements necessary to grant to the Collateral Agent a perfected security interest, with the priority required by the Intercreditor Agreements, subject only to Permitted Liens, in such after-acquired property and to have such after-acquired property added to the Collateral, and thereupon all provisions of this Indenture and the Security Documents relating to the Collateral shall be deemed to relate to such after-acquired property to the same extent and with the same force and effect.

(b) Upon the creation or acquisition of any Domestic Subsidiary after the Issue Date (other than any Excluded Subsidiary) that is required to become a Guarantor under this Indenture, such Domestic Subsidiary, at its sole expense, shall execute and deliver such amendments to the Security Documents or such other documents necessary to cause such new Subsidiary to become a party to any applicable Security Documents and grant to the Collateral Agent a perfected security interest, with the priority required by the Intercreditor Agreements, subject only to Permitted Liens, in such new Subsidiary, and thereupon all provisions of this Indenture and the Security Documents relating to the Collateral shall be deemed to relate to the Collateral of such new Subsidiary to the same extent and with the same force and effect.

SECTION 11.6. Negative Pledge. The Issuer and each Guarantor shall not further pledge the Collateral as security or otherwise, subject to Permitted Liens; provided, however, that the Issuer, subject to compliance with Section 4.9 and Section 4.12, shall be permitted to issue an unlimited aggregate principal amount of Additional Notes, all of which may be secured by the Collateral.

SECTION 11.7. Release of Liens on the Collateral.

(a) The Liens on the Collateral will be released with respect to the Notes and the Guarantees, as applicable:

121

(b) The Issuer and each Guarantor will furnish to the Trustee and the Collateral Agent, prior to each proposed release of Collateral pursuant to Section 11.7(a)(1) through (8) or pursuant to the Security Documents:

(c) Upon compliance by the Issuer or the Guarantors, as the case may be, with the conditions precedent set forth above, and upon delivery by the Issuer or such Guarantor to the Trustee an Opinion of Counsel to the effect that such conditions precedent have been complied with, the Trustee shall direct the Collateral Agent to promptly cause to be released and reconveyed to the Issuer or the relevant Guarantor, as the case may be, the released Collateral, and take all other actions reasonably requested by the Issuer in connection therewith, at the Issuer’s expense.

Subject to the provisions of the Security Documents, the Trustee or the Collateral Agent shall have the power, but not the obligation, to institute and to maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Security Documents or this Indenture, and such suits and proceedings as the Trustee or the Collateral Agent may deem expedient to preserve or protect its interest and the interests of the Holders in the Collateral (including the power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders or the Trustee).

122

(b) The Trustee or the Collateral Agent shall not be responsible for the existence, genuineness or value (or diminution of value) of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action on its part hereunder, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Issuer to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee or the Collateral Agent shall have no responsibility for recording, filing, re-recording or refiling any financing statement, continuation statement, document, instrument or other notice in any public office at any time or times or to otherwise take any action to perfect or maintain the perfection of any security interest granted to it under the Security Documents or otherwise. Beyond the exercise of reasonable care in the custody thereof, the Trustee and the Collateral Agent shall have no duty as to any Collateral in their possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. The Trustee and the Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in their possession if the Collateral is accorded treatment substantially equal to that which they accord their own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee or the Collateral Agent, as the case may be, in good faith. The Trustee and the Collateral Agent shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture or the Security Documents by the Issuer or the Guarantors.

(c) Where any provision of this Indenture requires that additional property or assets be added to the Collateral, the Issuer and each Guarantor, as applicable, shall deliver to the Trustee or the Collateral Agent the following:

123

(d) The Trustee or the Collateral Agent, in giving any consent or approval under the Security Documents, shall be entitled to receive, as a condition to such consent or approval, an Officers’ Certificate and an Opinion of Counsel to the effect that the action or omission for which consent or approval is to be given is authorized and permitted according to the terms of this Indenture and the Security Documents, and the Trustee or the Collateral Agent shall be fully protected in giving such consent or approval on the basis of such Officers’ Certificate and Opinion of Counsel.

SECTION 11.9. Information Regarding Collateral.

(a) The Issuer will furnish to the Collateral Agent within ten Business Days, with respect to the Issuer or any Guarantor, written notice of any change in such Person’s (1) legal name, (2) jurisdiction of organization or formation, (3) identity or corporate structure or (4) Organizational Identification Number. Promptly upon the occurrence of any of the foregoing, the Issuer and the Guarantors will make all filings under the Uniform Commercial Code and any other applicable laws that are required by this Indenture and/or the Security Documents in order for the Collateral to be made subject to the Lien of the Collateral Agent under this Indenture and/or the Security Documents in the manner and to the extent required by this Indenture or any of the Security Documents and shall take all necessary action so that such Lien is perfected with the same priority as immediately prior to such change to the extent required by this Indenture and/or the Security Documents. The Issuer will deliver to the Collateral Agent evidence of filing of all additional financing statements and other executed documents reasonably necessary to maintain the validity, perfection and priority of the security interests provided for in this Indenture and/or the Security Documents. The Issuer shall promptly notify the Collateral Agent in writing if any material portion of the Collateral is damaged, destroyed or condemned.

(b) The Issuer shall deliver to the Trustee and the Collateral Agent an Officers’ Certificate attaching supplemental schedules required under the Security Documents to the extent required under and at the same time as similar supplemental schedules are delivered to the Term Loan Credit Agreement Collateral Agent.

SECTION 12.10. Execution in Counterparts. This Indenture may be executed in two or more counterparts, which when so executed shall constitute one and the same agreement.

Except with respect to authentication of the Notes by the Trustee or an authenticating agent, 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.

SECTION 12.11. Table of Contents, Headings, Etc. The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

SECTION 12.12. 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

128

required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 12.12.

(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.

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

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

(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

129

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 Issuer’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Issuer and to each Holder in the manner set forth in Section 12.1.

(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 Issuer 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.

(j) With respect to any record date set pursuant to this Section 12.12, 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 in the manner set forth in Section 12.1, 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 12.12, 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).

130

SECTION 12.13. 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, epidemics and pandemics, 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 12.14. 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 12.15. 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 Issuer agrees that it will provide the Trustee with information about the Issuer as the Trustee may reasonably request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

(Back of 4.125% Senior Secured Note)

4.125% Senior Secured Notes due 2028

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

(1) Interest. Vertiv Group Corporation, a Delaware corporation, and any successor thereto (the “Company”) promises to pay interest on the unpaid principal amount of this 4.125% Senior Secured Note due 2028 (a “Note”) at a fixed rate of 4.125% per annum. The Issuer will pay interest in U.S. dollars semiannually in arrears on May 15 and November 15, commencing on May 15, 2022 (each an “Interest Payment Date”) or if any such day is not a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, and no additional interest shall accrue solely as a result of such delayed payment. Interest on the Notes shall accrue from the most recent date to which interest has been paid, or, if no interest has been paid, from and including the date of issuance. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Code) 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 Code) 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. The Issuer will pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders at the close of business on the May 1 and November 1 preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. If a Holder having an aggregate principal amount of more than $5,000,000 has given written wire transfer instructions to that holder’s U.S. dollar account within the United States to the Trustee at least ten Business Days prior to the applicable Interest Payment Date, the Issuer will make all payments of principal, premium and interest, on such Holder’s Notes by wire transfer of immediately available funds to the account specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Trustee or Paying Agent unless the Issuer elects to make interest payments by wire or check mailed to the Holders at their addresses set forth in the register of Holders. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

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

A-7

(3) Paying Agent and Registrar. Initially, UMB Bank, N.A. shall act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder, and the Issuer and/or any Restricted Subsidiaries may act as Paying Agent or Registrar.

(4) Indenture. The Issuer issued the Notes under an Indenture, dated as of October 22, 2021 (the “Indenture”), among Holdings, the Issuer, the Subsidiary Guarantors thereto, the Trustee and the Collateral Agent. The terms of the Notes include those stated in the Indenture. To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. The Initial Notes issued on the Issue Date were initially issued in an aggregate principal amount of $850,000,000. The Indenture permits the issuance of Additional Notes subject to compliance with certain conditions.

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

(5) Optional Redemption.

(a) The Notes may be redeemed, in whole or in part, at any time or from time to time prior to November 15, 2024 at the option of the Issuer, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium 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).

(c) In the event that before November 15, 2024, the Issuer receives net cash proceeds from one or more Equity Offerings, the Issuer may use an amount not greater than the amount of such net cash proceeds to redeem up to 40.0% of the original aggregate principal amount of all Notes issued (calculated after giving effect to any issuance of Additional Notes) at a redemption price of 104.125% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date (subject to the rights of Holders on the relevant regular record date to receive interest due on the relevant interest payment date that is on or prior to the applicable redemption date); provided that:

A-8

(2) the redemption date is within 120 days of the consummation of any such Equity Offering.

(6) Special Mandatory Redemption.

(a) If (i) the consummation of the Acquisition does not occur on or before December 31, 2021 (or such later date if the end date is extended pursuant to the terms of the Acquisition Agreement) (the “End Date”) or (ii) the Issuer delivers a notice to the Trustee stating it has determined that the consummation of the Acquisition will not occur on or before the End Date (the earlier of the date of delivery of such notice and the End Date, the “Acquisition Deadline”), the Issuer will be required to redeem all of the Notes issued on the Issue Date (the “Special Mandatory Redemption”). The Special Mandatory Redemption will be required to occur by a date no later than ten days after the Acquisition Deadline, upon three days’ notice (the “Special Mandatory Redemption Date”) and at a redemption price equal to 100% of aggregate principal amount of the Notes, plus accrued and unpaid interest on the Notes being redeemed, if any, to, but excluding, the Special Mandatory Redemption Date.

(8) Notice of Redemption. Notice of redemption (other than a Special Mandatory Redemption) shall be delivered at least ten days but not more than 60 days before the redemption date (except that notices may be delivered more than 60 days before an expected redemption date if the notice is issued in accordance with Article VIII of the Indenture) to each Holder whose Notes are to be redeemed in accordance with Section 12.1 of the Indenture. Notices of redemption may be subject to conditions precedent as set forth in the Indenture. Notes in denominations larger than $2,000 may be redeemed in part so long as no partial redemption results in a Note having a principal amount of less than $2,000.

(9) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in initial denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of the Notes may be registered and the Notes may be exchanged as provided in the Indenture. The Registrar, the Trustee and the Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Holders will be required to pay all taxes due on transfer. The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of 15 days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

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

Re: Vertiv Group Corporation (the “Company”) 4.125% Senior Secured Notes due 2028 (the “Notes”)

Ladies and Gentlemen:

This certificate is delivered to request a transfer of $_____________ principal amount of the Notes.

Upon transfer, the Notes would be registered in the name of the new beneficial owner as follows:

Name:                                                                  

Address:

The undersigned represents and warrants to you that:

1. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such an institutional “accredited investor” at least $250,000 principal amount of the Notes, and we are acquiring the Notes not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of our investment in the Notes, and we invest in or purchase securities similar to the Notes in the normal course of our business. We and any accounts for which we are acting are each able to bear the economic risk of our or its investment.

D-1

2. We understand that the Notes have not been registered under the Securities Act (or the securities laws of any state or other jurisdiction) and, unless so registered, may not be reoffered, sold, assigned, transferred, pledged, encumbered or otherwise disposed of except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Notes to offer, sell or otherwise transfer such Notes prior to the date that is one year after the later of the date of original issue, the original issue date of any additional Notes and the last date on which the Issuer or any affiliate of the Issuer was the owner of such Notes (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuer or any of its subsidiaries, (b) pursuant to a registration statement that has been declared effective under the Securities Act, (c) for so long as the Notes are eligible for resale pursuant to Rule 144A under the Securities Act, in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a “qualified institutional buyer” under Rule 144A under the Securities Act (a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States to non-U.S. persons, in compliance with Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is not a QIB and is purchasing for its own account or for the account of another institutional “accredited investor,” in each case in a minimum principal amount of Notes of $250,000, for investment purposes and not with a view to or for offer or sale in connection with any distribution in violation of the Securities Act or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Notes is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Issuer and UMB Bank, N.A., as trustee (the “Trustee”), which shall provide, among other things, that the transferee is an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring such Notes for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Issuer and the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Restriction Termination Date of the Notes pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other information satisfactory to the Issuer and the Trustee.

3. We [are] [are not] an affiliate of the Issuer.
