For purposes of making the computation referred to above, Investments, acquisitions, dispositions, amalgamations, mergers (including the Transactions), consolidations and discontinued operations (as determined in accordance with GAAP), Subsidiary designations and any operational changes or cost savings initiatives that the Issuer or any of its Restricted Subsidiaries has determined to make or has made during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Fixed Charge Coverage Ratio Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, amalgamations, mergers, consolidations, discontinued operations and operational changes (and the change in any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged, amalgamated or consolidated with or into the Issuer or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, amalgamation, merger, consolidation, discontinued operation or operational change that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, discontinued operation, merger, amalgamation, consolidation or operational change had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to an Investment, acquisition, disposition, amalgamation, merger (including the Transactions), consolidation, discontinued operation or operational change, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Issuer (and may include (to the extent not already included in EBITDA), (a) cost savings (including sourcing), operating expense reductions and other operating improvements or synergies resulting from such Investment, acquisition, disposition, amalgamation, merger, consolidation (including the Transactions), discontinued operation or operational change, which is being given pro forma effect that have been or are expected to be realized and reasonably identifiable and factually supportable and are reasonably anticipated to be realized within 24 months after the change, acquisition or disposition that is expected to result in such cost savings, expense reductions, or operating improvements and other synergies and (b) adjustments of the nature used in connection with the calculation of “Adjusted EBITDA” and “Pro Forma Combined Adjusted EBITDA” as set forth in footnote (2) to “Summary—Summary Historical Financial and Unaudited Pro Forma Condensed Combined Financial and Other Data” in the Offering Memorandum). If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Fixed Charge Coverage Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate. Interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such indebtedness during the applicable period.

For purposes of this definition, any amount in a currency other than U.S. dollars will be converted to U.S. dollars based on the average exchange rate for such currency for the most recent twelve month period immediately prior to the date of determination in a manner consistent with GAAP.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01 hereof) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 1.04.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgements of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof.

(g) Without limiting the generality of the foregoing, a Holder, including the Depositary, 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 the Depositary may provide its proxy to the beneficial owners of interests in any such Global Security through such Depositary’s standing instructions and customary practices.

THE SECURITIES

SECTION 2.01 Amount of Securities. The aggregate principal amount of Securities which may be authenticated and delivered under this Indenture on the Issue Date is $625,000,000.

The Issuer may from time to time after the Issue Date issue Additional Securities under this Indenture in an unlimited principal amount, so long as (i) the incurrence of the Indebtedness represented by such Additional Securities is at such time permitted by Section 4.03 hereof and (ii) such Additional Securities are issued in compliance with the other applicable provisions of this Indenture. With respect to any Additional Securities issued after the Issue Date (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities pursuant to Section 2.07, 2.08, 2.09, 2.10, 3.06, 3.08, 4.09(c) or Appendix A hereof (the “Appendix”)), there shall be (a) established in or pursuant to a resolution of the board of directors (or similar governing body) of the Issuer and (b) (i) set forth or determined in the manner provided in an Officer’s Certificate of the Issuer or (ii) established in one or more indentures supplemental hereto, prior to the issuance of such Additional Securities:

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

(2) the issue price and issuance date of such Additional Securities, including the date from which interest on such Additional Securities shall accrue; and

(3) if applicable, that such Additional Securities shall be issuable in whole or in part in the form of one or more Global Securities and, in such case, the respective depositaries for such Global Securities, the form of any legend or legends which shall be borne by such Global Securities in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Section 2.2 of the Appendix in which any such Global Security may be exchanged in whole or in part for Additional Securities registered, or any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof.

If any of the terms of any Additional Securities are established by action taken pursuant to a resolution of the board of directors (or similar governing body) of the Issuer, a copy of an appropriate record of such action shall be certified by the Secretary or any Assistant Secretary of the Issuer and delivered to the Trustee at or prior to the delivery of the Officer’s Certificate of the Issuer or the indenture supplemental hereto setting forth the terms of the Additional Securities.

The Securities, including any Additional Securities, shall be treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase; provided that if any Additional Securities are not fungible with the original notes for U.S. federal income tax purposes, such Additional Securities will have a separate CUSIP or ISIN number.

SECTION 2.02 Form and Dating. Provisions relating to the Securities are set forth in the Appendix, which is hereby incorporated into and expressly made a part of this Indenture. The (i) Original Securities and the Trustee’s certificate of authentication and (ii) any Additional Securities and the Trustee’s certificate of authentication shall each be substantially in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each Security shall be dated the date of its authentication. The Securities shall be issuable only in registered form without interest coupons and in denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

SECTION 2.03 Execution and Authentication. The Trustee shall authenticate and make available for delivery upon a written order of the Issuer signed by one Officer of the Issuer (an “Authentication Order”) (a) Original Securities for original issue on the date hereof in an aggregate principal amount of $625,000,000 and (b) subject to the terms of this Indenture, Additional Securities in an aggregate principal amount to be determined at the time of issuance and specified therein. Such Authentication Order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated. Notwithstanding anything to the contrary in this Indenture or the Appendix, any issuance of Additional Securities after the Issue Date shall be in a principal amount of at least $2,000 and integral multiples of $1,000 in excess of $2,000.

One Officer of the Issuer shall sign the Securities for the Issuer by manual or facsimile signature.

If an Officer of the Issuer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be entitled to any benefit under this Indenture or valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

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

SECTION 2.04 Registrar and Paying Agent.

(a) The Issuer shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and (ii) a Paying Agent. The Registrar shall keep a register of the Securities and of their transfer and exchange. The

Issuer may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars. The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuer initially appoints the Trustee as Registrar, Paying Agent and the Custodian with respect to the Global Securities. The Issuer initially appoints DTC to act as Depositary with respect to the Global Securities.

(b) The Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07 hereof. The Issuer or any of its domestically organized Wholly-Owned Subsidiaries may act as Paying Agent or Registrar.

(c) The Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee and without prior notice to any Holder; provided, however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (ii) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above. The Registrar or Paying Agent may resign at any time upon written notice to the Issuer and the Trustee; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance with Section 7.08 hereof.

SECTION 2.05 Paying Agent to Hold Money in Trust. One Business Day prior to or on each due date of the principal of and interest on any Security, the Issuer shall deposit with a Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by a Paying Agent for the payment of principal of and interest on the Securities, and shall notify the Trustee in writing of any default by the Issuer in making any such payment. If the Issuer or a Wholly-Owned Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it in trust for the benefit of the Persons entitled thereto. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. Upon complying with this Section, a Paying Agent shall have no further liability for the money delivered to the Trustee. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee shall serve as Paying Agent for the Securities.

SECTION 2.06 Holder Lists. The Registrar shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee, in writing at least five (5) Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

SECTION 2.07 Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested if its requirements therefor of this Indenture are met. When Securities are presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Securities at the Registrar’s request. The Issuer may require payment of a sum sufficient to pay all taxes, assessments or other governmental charges in connection with any transfer or exchange pursuant to this Section. The Issuer shall not be required to make, and the Registrar need not register, transfers or exchanges of any Securities (i) selected for redemption (except, in the case of Securities to be redeemed in part, the portion thereof not to be redeemed) (ii) for a period of 15 days before the mailing of a notice of redemption of Securities to be redeemed or (iii) between a regular record date and the next succeeding interest payment date.

Prior to the due presentation for registration of transfer of any Security, the Issuer, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Issuer, any Guarantor, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

Any Holder of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to be reflected in a book entry.

All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange.

SECTION 2.08 Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the UCC are met, such that the Holder (a) satisfies the Issuer or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer or the Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the UCC (a “protected purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity bond sufficient in the judgment of (i) the Trustee to protect the Trustee or (ii) the Issuer to protect the Issuer, the Trustee, a Paying Agent and the Registrar from any loss that any of them may suffer if a Security is replaced. The Issuer and the Trustee may charge the Holder for their expenses in replacing a Security (including without limitation, attorneys’ fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Issuer in its discretion may pay such Security instead of issuing a new Security in replacement thereof.

Every replacement Security is an additional obligation of the Issuer.

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

SECTION 2.09 Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation, those paid pursuant to Section 2.08 hereof and those described in this Section as not outstanding. Subject to Section 12.05 hereof, a Security does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Security.

If a Security is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee and the Issuer receive proof satisfactory to them that the replaced Security is held by a protected purchaser.

If a Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date or any date of purchase pursuant to an offer to purchase money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed, maturing or purchased, as the case may be, and no Paying Agent is prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.10 Temporary Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate for temporary Securities. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender of such temporary Securities at the office or agency of the Issuer, without charge to the Holder. Until such exchange, temporary Securities shall be entitled to the same rights, benefits and privileges as Definitive Securities.

SECTION 2.11 Cancellation. The Issuer at any time may deliver Securities to the Trustee for cancellation. The Registrar and each Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of cancelled Securities in accordance with its customary procedures (subject to the record retention requirement of the Exchange Act and the Trustee). The Issuer may not issue new Securities to replace Securities they have redeemed, paid or delivered to the Trustee for cancellation. The Trustee shall not authenticate Securities in place of cancelled Securities other than pursuant to the terms of this Indenture.

SECTION 2.12 Defaulted Interest. If the Issuer defaults in a payment of interest on the Securities, the Issuer shall pay the defaulted interest then borne by the Securities (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Issuer may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any such special record date and payment and shall promptly send or cause to be sent to each affected Holder and the Trustee a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

SECTION 2.13 CUSIP Numbers, ISINs, etc. The Issuer in issuing the Securities may use CUSIP numbers, ISINs and “Common Code” numbers (if then generally in use) and, if so, the Trustee shall use CUSIP numbers, ISINs and “Common Code” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or as contained in any notice of a redemption that reliance may be placed only on the other identification numbers printed on the Securities and that any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly advise the Trustee in writing of any change in the CUSIP numbers, ISINs and “Common Code” numbers.

SECTION 2.14 Calculation of Principal Amount of Securities. The aggregate principal amount of the Securities, at any date of determination, shall be the principal amount of the Securities outstanding at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the Securities, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have so consented, by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.09 and Section 12.05 hereof. Any such calculation made pursuant to this Section 2.14 shall be made by the Issuer and delivered to the Trustee pursuant to an Officer’s Certificate of the Issuer. The Trustee may accept as conclusive evidence of fact or the correctness of any calculation and shall be fully protected in relying upon the Officer’s Certificate provided to it by the Issuer and shall not have any liability or responsibility for any calculation performed in connection herewith or for any information used in connection with any such calculation.

ARTICLE 3

REDEMPTION

Such notice shall be accompanied by an Officer’s Certificate from the Issuer to the effect that such redemption will comply with the conditions herein. Any such notice may be cancelled at any time by written notice to the Trustee prior to notice of such redemption being sent to any Holder and shall thereby be void and of no effect.

SECTION 3.04 Selection of Securities to Be Redeemed. In the case of any partial redemption, the Trustee shall select the Securities to be redeemed by lot and otherwise in accordance with the customary procedures of the relevant Depositary; provided that no Securities of $2,000 or less shall be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them that the Trustee selects shall be in principal amounts of $2,000 or any integral multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Issuer as soon as practicable of the Securities or portions of Securities to be redeemed.

After the redemption date, upon surrender of the Security to be redeemed in part only, a new Security or Securities in principal amount equal to the unredeemed portion of the original Security representing the same Indebtedness to the extent not redeemed shall be issued in the name of the Holder of the Securities upon cancellation of the original Security (or appropriate book entries shall be made to reflect such partial redemption).

SECTION 3.05 Notice of Optional Redemption.

(a) At least 30 days but not more than 60 days before a redemption date pursuant to the optional redemption provisions of Paragraph 5 of the Security, the Issuer shall mail or cause to be mailed by first-class mail (or otherwise delivered in accordance with the procedures of the Depositary) a notice of redemption to each Holder whose Securities are to be redeemed (except that such notice of redemption may be mailed (or otherwise delivered in accordance with the procedures of the Depositary) (i) more than 60 days prior to a redemption date if the notice is issued in connection with Section 8.01 hereof or (ii) at least 15 days before a redemption date if the redemption is occurring pursuant to Paragraph 5(d) of the Security).

Any such notice shall identify the Securities to be redeemed and shall state:

Once notice of redemption is mailed or sent in accordance with Section 3.05 hereof, Securities called for redemption become due and payable on the redemption date and at the redemption price stated in the notice, except as provided in Paragraph 5(d) of the “Optional Redemption” provisions of the Security. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price stated in the

notice, plus accrued interest to, but not including, the redemption date. The notice, if sent in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.07 Deposit of Redemption Price. With respect to any Securities, one Business Day prior to the redemption date, the Issuer shall deposit with the Paying Agent (or, if the Issuer or a Wholly-Owned Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities or portions of Securities called for redemption that have been delivered by the Issuer to the Trustee for cancellation.

Accrual of interest or dividends, the accretion of accreted value, the accretion or amortization of original issue discount, and the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as the case may be, of the same class, accretion or amortization of original issue discount or liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or Preferred Stock for purposes of this Section 4.03. Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness; provided that the incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this Section 4.03.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed or first incurred (whichever yields the lower U.S. dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness (plus premium (including tender premiums), fees, defeasance costs, accrued interest and expenses including original issue discount, upfront fees or similar fees) does not exceed the principal amount of such Indebtedness being refinanced.

The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

In the event that the Issuer or a Restricted Subsidiary enters into or increases commitments under a revolving credit facility, the Fixed Charge Coverage Ratio, the Consolidated First Lien Secured Debt Ratio, the Consolidated Secured Debt Ratio or the Consolidated Total Leverage Ratio, as applicable, for borrowings and reborrowings thereunder (and including the issuance and creation of letters of credit and bankers’ acceptances thereunder) will, at the Issuer’s option as elected on the date the Issuer or a Restricted Subsidiary, as the case may be, enters into or increases such commitments, either (a) be determined on the date of such revolving credit facility or such increase in commitments (assuming that the full amount thereof has been borrowed as of such date), and, if such Fixed Charge Coverage Ratio, the Consolidated First Lien Secured Debt Ratio, the Consolidated Secured Debt Ratio or the Consolidated Total Leverage Ratio, as applicable, test is satisfied with respect thereto at such time, any borrowing or reborrowing thereunder (and the issuance and creation of letters of credit and bankers’ acceptances thereunder) will be permitted under this covenant irrespective of the Fixed Charge Coverage Ratio, the Consolidated First Lien Secured Debt Ratio, the Consolidated Secured Debt Ratio or the Consolidated Total Leverage Ratio, as applicable, at the time of any borrowing or reborrowing (or issuance or creation of letters of credit or bankers’ acceptances thereunder) (the committed, but undrawn amount permitted to be borrowed or reborrowed (and the issuance and

creation of letters of credit and bankers’ acceptances) on a date pursuant to the operation of this clause (a) shall be the “Reserved Indebtedness Amount” as of such date for purposes of the Fixed Charge Coverage Ratio, the Consolidated First Lien Secured Debt Ratio, the Consolidated Secured Debt Ratio or the Consolidated Total Leverage Ratio, as applicable) or (b) be determined on the date such amount is borrowed pursuant to any such facility or increased commitment.

The Issuer shall not, and shall not permit any Subsidiary Guarantor to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness) that is contractually subordinated or junior in right of payment to any Indebtedness of the Issuer or such Subsidiary Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Securities or such Subsidiary Guarantor’s Guarantee within 90 days of the incurrence of such Indebtedness to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Subsidiary Guarantor, as the case may be.

For purposes of this Indenture, Indebtedness that is unsecured shall not be deemed to be subordinated or junior to Secured Indebtedness merely because it is unsecured, and senior indebtedness shall not be deemed to be subordinated or junior to any other senior indebtedness merely because it has a junior priority with respect to the same collateral.

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under clauses (xi), (xvi) and (xviii) this Section 4.04(b), no Default shall have occurred and be continuing or would occur as a consequence thereof. In determining whether any Restricted Payment is permitted by this Section 4.04, the Issuer and its Restricted Subsidiaries may allocate all or any portion of such Restricted Payment among the categories described in clauses (i) through (xix) of this Section 4.04(b) or among such categories and the types of Restricted Payments described in Section 4.04(a) hereof (including categorization in whole or in part as one or more of the clauses contained in the definition of “Permitted Investments”); provided that, at the time of such allocation, all such Restricted Payments, or allocated portions thereof, would be permitted under the various provisions of this Section 4.04 and provided, further that the Issuer and its Restricted Subsidiaries may reclassify all or a portion of such Restricted Payment or Permitted Investment in any manner that complies with this Section 4.04 (based on circumstances existing at the time of such reclassification), and following such reclassification such Restricted Payment or Permitted Investment shall be treated as having been made pursuant to only the clause or clauses of this Section 4.04 to which such Restricted Payment or Permitted Investment has been reclassified.

The Issuer shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the second to last sentence of the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Issuer and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Investments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation shall be permitted only if a Restricted Payment or Permitted Investment in such amount would be permitted at such time, whether pursuant to Section 4.04(a) or clause (vii), (x), (xi) or (xviii) of Section 4.04(b) hereof or pursuant to the definition of “Permitted Investment” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. Unrestricted Subsidiaries shall not be subject to any of the restrictive covenants set forth in this Indenture.

For the avoidance of doubt, this Section 4.04 shall not restrict the making of any “AHYDO catch up payment” with respect to, and required by the terms of, any Indebtedness of the Issuer or any of its Restricted Subsidiaries permitted to be incurred under the terms of this Indenture.

SECTION 4.05 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a) (i) pay dividends or make any other distributions to the Issuer or any of its Restricted Subsidiaries on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits; or (ii) pay any Indebtedness owed to the Issuer or any of its Restricted Subsidiaries;

(b) make loans or advances to the Issuer or any Guarantor; or

SECTION 4.06 Asset Sales.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, consummate an Asset Sale, unless:

(i) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration (including by way of relief from, or by any other Person assuming responsibility for, any liabilities, contingent or otherwise, in connection with such Asset Sale) at the time of such Asset Sale at least equal to the fair market value as determined in good faith by the Issuer (such fair market value to be determined on the date of contractually agreeing to such Asset Sale) of the assets sold or otherwise disposed of; and

(ii) except in the case of a Permitted Asset Swap, at least 75% of the consideration received therefor by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of Cash Equivalents; provided that the amount of:

(a) any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto, or if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Issuer’s or such Restricted Subsidiary’s balance sheet or in the footnotes thereto if such incurrence or accrual had taken place on or prior to the date of such balance sheet, as determined in good faith by the Issuer) of the Issuer or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Securities or the Guarantees, that are assumed by the transferee of any such assets or that are otherwise cancelled or terminated in connection with the transaction with such transferee and for which the Issuer and all of its Restricted Subsidiaries have been validly released by all creditors in writing,

(b) any securities, notes or other obligations or assets received by the Issuer or such Restricted Subsidiary from such transferee (including earnouts or similar obligations) that are converted by the Issuer or such Restricted Subsidiary into Cash Equivalents, or by their terms are required to be satisfied for Cash Equivalents (to the extent of the Cash Equivalents received) within 180 days following the closing of such Asset Sale,

(c) Indebtedness of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that the Issuer and each other Restricted Subsidiary are released from any guarantee of payment of such Indebtedness in connection with the Asset Sale, and

(d) any Designated Non-cash Consideration received by the Issuer or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (d) that is at that time outstanding, not to exceed the greater of (x) $75.0 million and (y) 1.75% of Consolidated Total Assets at the time of the receipt of such Designated Non-cash Consideration (or, at the Issuer’s option, at the time of contractually agreeing to such Asset Sale), with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value,

shall be deemed to be Cash Equivalents for purposes of this Section 4.06(a) and for no other purpose.

(b) Within 365 days after the receipt of any Net Proceeds of any Asset Sale of Collateral (such Net Proceeds, “Collateral Net Proceeds”), the Issuer or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale,

(i) to repay (a) Indebtedness constituting Pari Passu Obligations (other than the Securities) under the Pari Passu Intercreditor Agreement (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto), provided that, if the Issuer or any Restricted Subsidiary shall so reduce any such Pari Passu Obligations, the Issuer will equally and ratably reduce Obligations under the Securities as provided under Paragraph 5 of the “Optional Redemption” provisions of the Security, through open-market purchases (provided that such purchases are at or above 100.0% of the principal amount thereof or, if less, the accreted value thereof) or by making an offer whether or not accepted (in accordance with the procedures set forth below for a Collateral Asset Sale Offer) to all Holders to purchase their Securities at a purchase price equal to 100.0% of the principal amount thereof or, if less, the accreted value thereof, plus accrued and unpaid interest on the principal amount of Securities so purchased, or (b) to the extent such Net Proceeds constitute proceeds from ABL Priority Collateral, Indebtedness under the ABL Credit Agreement (and to effect a corresponding reduction in commitments under the ABL Credit Agreement);

provided, that in the case of clause (a) above, (1) if an offer to purchase any Indebtedness constituting Pari Passu Obligations under the Pari Passu Intercreditor Agreement is made, such amount will be deemed repaid to the extent of the amount of such offer, whether or not accepted by the holders of such Indebtedness, and no Collateral Net Proceeds in the amount of such offer will be deemed to exist following such offer, and (2) if the holder of any Indebtedness constituting Pari Passu Obligations under the Pari Passu Intercreditor Agreement declines the repayment of such Indebtedness constituting Pari Passu Obligations under the Pari Passu Intercreditor Agreement owed to it from such Collateral Net Proceeds, such amount will be deemed repaid to the extent of the declined Collateral Net Proceeds;

(ii) to make (a) an Investment in any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in the Issuer or any of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) capital expenditures or (c) acquisitions of other properties or assets, in the case of each of (a), (b) and (c), used or useful in a Similar Business;

(iii) to make an Investment in (a) any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in the Issuer or any of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) properties or (c) other assets that, in the case of each of (a), (b) and (c), replace the businesses, properties and/or other assets that are the subject of such Asset Sale; or

(iv) any combination of the foregoing;

provided that, in the case of clauses (ii) and (iii) above, a binding commitment entered into not later than such 365th day shall extend the period for such Investment or other payment for an additional 180 days after the end of such 365-day period so long as the Issuer or such other Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, the Issuer or such Restricted Subsidiary enters into another Acceptable Commitment (a “Second Commitment”) within such 180-day period; provided, further, that (x) if any Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied or (y) such Net Proceeds are not actually so invested or paid in accordance with clause (2) above by the end of such 180-day period, then such Net Proceeds shall constitute Excess Proceeds on the date of such cancellation or termination, or such 180th day, as applicable.

Any Collateral Net Proceeds from the Asset Sale of Collateral that are not invested or applied as provided and within the time period set forth in the preceding paragraph will be deemed to constitute “Collateral Excess Proceeds.” When the aggregate amount of Collateral Excess Proceeds exceeds $40.0 million, the Issuer shall make an offer to all Holders of the Securities and, if required by the terms of any Pari Passu Obligations under the Pari Passu Intercreditor Agreement, to the holders of such other Pari Passu Obligations (a “Collateral Asset Sale Offer”) to purchase the maximum aggregate principal amount of the Securities and such other Pari Passu Obligations that is in an amount equal to at least $2,000, that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100.0% of the principal amount thereof (or accreted value thereof, if less), plus accrued and unpaid interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer will commence a Collateral Asset Sale Offer with respect to Collateral Excess Proceeds within thirty Business Days after the date that Collateral Excess Proceeds exceed $40.0 million by delivering the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Issuer may satisfy the foregoing obligations with respect to any Collateral Net Proceeds from a Collateral Asset Sale by making a Collateral Asset Sale Offer (an “Advance Offer”) with respect to all or a portion of any Collateral Net Proceeds (the “Advance Portion”) prior to the expiration of the relevant 365 days (or such longer period provided above) or with respect to Collateral Excess Proceeds of $40.0 million or less.

To the extent that the aggregate amount of Securities and such other Pari Passu Obligations tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds (or in the case of an Advance Offer, the Advance Portion), the Issuer shall be deemed to have complied with its obligations under this Indenture and may retain any remaining Collateral Excess Proceeds to be used for general corporate purposes. If the aggregate principal amount of Securities and such other Pari Passu Obligations tendered by holders thereof exceeds the amount of Collateral Excess Proceeds, the Trustee, subject to the Depositary’s customary procedures, shall select the Securities and the Issuer shall select the other Pari Passu Obligations to be purchased on a pro rata basis based on the accreted value or principal amount of the Securities or such other Pari Passu Obligations tendered with adjustments as necessary so that no Securities or other Pari Passu Obligations will be repurchased in part in an unauthorized denomination. Upon completion of any such Collateral Asset Sale Offer, the amount of Collateral Excess Proceeds shall be reset at zero. Additionally, upon consummation or expiration of any Advance Offer, any remaining Collateral Net Proceeds shall not be deemed Collateral Excess Proceeds and the Issuer may use such Collateral Net Proceeds in any manner not prohibited by this Indenture.

(c) Within 365 days after the receipt of any Net Proceeds of any Asset Sale of non-Collateral, the Issuer or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale:

(i) to repay (1) Obligations under any Indebtedness (other than Subordinated Indebtedness) of the Issuer or any Restricted Subsidiary (and if the Indebtedness repaid is revolving credit indebtedness, to correspondingly reduce commitments with respect thereto); provided that the Issuer shall equally and ratably reduce Obligations under the Securities as provided under paragraph 5 of the Security, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof or, if less, the accreted value thereof) or by making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase their Securities at 100% of the principal amount thereof or, if less, the accreted value thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Securities that would otherwise be prepaid or (2) Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Issuer or another Restricted Subsidiary;

provided, that in the case of clause (1) above, (x) if an offer to purchase any Indebtedness of the Issuer or any Restricted Subsidiary is made, such amount will be deemed repaid to the extent of the amount of such offer, whether or not accepted by the holders of such Indebtedness, and no Net Proceeds in the amount of such offer will be deemed to exist following such offer and (y) if the holder of any Indebtedness of the Issuer or any Restricted Subsidiary declines the repayment of such Indebtedness owed to it from such Net Proceeds, such amount will be deemed repaid to the extent of the declined Net Proceeds;

(iii) to make an Investment in (a) any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in the Issuer or any of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) properties or (c) other assets that, in the case of each of (a), (b) and (c), replace the businesses, properties and/or other assets that are the subject of such Asset Sale; or

(iv) any combination of the foregoing;

provided that, in the case of clauses (ii) and (iii) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as the Issuer or such other Restricted Subsidiary enters into an Acceptable Commitment and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, the Issuer or such Restricted Subsidiary enters into a Second Commitment within 180 days of such cancellation or termination (or, if later, 365 days after the receipt of such Net Proceeds); provided further that if any Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds (as defined below).

Notwithstanding the foregoing, to the extent that any or all of the Net Proceeds of any Asset Sales (whether or not constituting Collateral) by a Foreign Subsidiary (a “Foreign Disposition”) is prohibited or delayed by applicable local law from being repatriated to the United States, the portion of such Net Proceeds so affected will not be required to be applied in compliance with this covenant, and such amounts may be retained by the applicable Foreign Subsidiary so long, but only so long, as the applicable local law will not permit repatriation to the United States (the Issuer hereby agreeing to use 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 Proceeds is permitted under the applicable local law, such repatriation will be promptly effected and such repatriated Net Proceeds will be applied (whether or not repatriation actually occurs) in compliance with this Section 4.06.

Any Net Proceeds from any Asset Sale that are not invested or applied as provided and within the time period set forth in this Section 4.06(c) (it being understood that any portion of such Net Proceeds used to make an offer to purchase Securities, as described in clause (i) of this Section 4.06(c), shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $40.0 million, the Issuer shall make an offer to all Holders and, at the option of the Issuer, to any holders of any Indebtedness that is pari passu with the Securities (“Pari Passu Indebtedness”) (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Securities and such Pari Passu Indebtedness that is at least $2,000 and an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in

cash in an amount equal to 100% of the principal amount thereof, or 100% of the accreted value thereof, if less, plus accrued and unpaid interest, if any, (or, in respect of such Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Pari Passu Indebtedness) to, but not including, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within thirty Business Days after the date that Excess Proceeds exceed $40.0 million by sending the notice required pursuant to the terms of this Indenture, with a copy to the Trustee, or otherwise in accordance with the procedures of DTC. The Issuer may satisfy the foregoing obligation with respect to such Net Proceeds by making an Advance Offer with respect to the Advance Portion in advance of being required to do so by this Indenture or with respect to Excess Proceeds of $40.0 million or less.

To the extent that the aggregate amount of Securities and such Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds(or in the case of an Advance Offer, the Advance Portion), the Issuer may use any remaining Excess Proceeds for general corporate purposes, subject to compliance with other covenants contained in this Indenture. If the aggregate principal amount of Securities and the Pari Passu Indebtedness surrendered in an Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Securities to be purchased in the manner described in Section 3.04 hereof. Selection of such Pari Passu Indebtedness will be made pursuant to the terms of such Pari Passu Indebtedness. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset to zero (regardless of whether there are any remaining Excess Proceeds upon such completion). Additionally, upon consummation or expiration of any Advance Offer, any remaining Net Proceeds shall not be deemed Excess Proceeds and the Issuer may use such Net Proceeds for any purpose not otherwise prohibited under this Indenture.

Pending the final application of any Collateral Net Proceeds or Net Proceeds pursuant to this Section 4.06, the holder of such Collateral Net Proceeds or Net Proceeds may apply such Collateral Net Proceeds or Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Collateral Net Proceeds or Net Proceeds in any manner not prohibited by this Indenture.

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to a Collateral Asset Sale Offer or an Asset Sale Offer, as applicable. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

SECTION 4.07 Special Mandatory Offer to Purchase

(a) Unless the Issuer has previously or concurrently sent a redemption notice with respect to all outstanding Securities as described under paragraph 5 of the Security and in accordance with the terms hereof, if a Triggering Event occurs, each Holder will have the right to require the Issuer to repurchase all or any part (equal to at least $2,000 and an integral multiple of $1,000 in excess thereof) of that Holder’s Securities pursuant to an offer (“Triggering Event Repurchase Offer”) for an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase.

(b) Within three Business Days following a Triggering Event, the Issuer shall electronically deliver or mail a notice to each Holder with a copy to the Trustee and the Paying Agent stating:

(i) that a Triggering Event has occurred and that such Holder has the right to require the Issuer to repurchase such Holder’s Securities at a repurchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date);

(ii) the repurchase date (which shall be no later than 45 days from the date of the Triggering Event);

(iii) the instructions determined by the Issuer, consistent with this covenant, that a Holder must follow in order to have its Securities purchased; and

(iv) if such notice is electronically delivered or mailed prior to the occurrence of a Triggering Event, that such Triggering Event Repurchase Offer is conditioned on the occurrence of such Triggering Event.

(c) For the avoidance of doubt, a Triggering Event Repurchase Offer may be made in advance of a Triggering Event, and be conditional upon such Triggering Event.

(d) Securities repurchased by the Issuer pursuant to a Triggering Event Repurchase Offer will either have the status of Securities issued but not outstanding or will be retired and canceled at the option of the Issuer.

(e) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to a Triggering Event Repurchase Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

SECTION 4.08 Transactions with Affiliates.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuer (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $15.0 million, unless:

(i) such Affiliate Transaction is on terms, taken as a whole, that are not materially less favorable to the Issuer or its relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis, or if in the good faith judgment of the board of directors of the Issuer, no comparable transaction is available with which to compare the Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Issuer or such Restricted Subsidiary from a financial point of view; and

(ii) the Issuer delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $30.0 million, a resolution adopted by the majority of the board of directors of the Issuer approving such Affiliate Transaction and set forth in an Officer’s Certificate of the Issuer certifying that such Affiliate Transaction complies with clause (i) above.

(b)	Section 4.08(a) hereof shall not apply to the following:

(i) transactions between or among the Issuer or any of its Restricted Subsidiaries, or an entity that becomes a Restricted Subsidiary as a result of such transaction, and any merger, consolidation or amalgamation of the Issuer and any direct or indirect parent of the Issuer; provided that such parent shall have no material liabilities and no material assets other than cash, Cash Equivalents and Capital Stock of the Issuer (or a parent company thereof) and such merger, consolidation or amalgamation is otherwise in compliance with the terms of this Indenture and effected for a bona fide business purpose;

(vi) any agreement as in effect as of the Issue Date, or any amendment, modification or extension thereof (so long as any such amendment is not disadvantageous in any material respect to the Holders when taken as a whole as compared to the applicable agreement as in effect on the Issue Date as determined in good faith by the Issuer) or any transaction contemplated thereby;

(b) Within 30 days following any Change of Control occurring after the Issue Date, the Issuer will send notice of such Change of Control Offer by first-class mail, with a copy to the Trustee, to each Holder of Securities to the registered address of such Holder or otherwise electronically in accordance with the procedures of DTC, with the following information:

(i) that a Change of Control Offer is being made pursuant to this Section 4.09, and that all Securities properly tendered pursuant to such Change of Control Offer will be accepted for payment by the Issuer at a repurchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the date of repurchase, subject to the right of Holders of record of the Securities at the close of business on the relevant record date to receive interest due on the relevant interest payment date falling prior to or on the purchase date;

(ii) the purchase price and the purchase date, which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed or otherwise delivered, subject to extension (in the case where such notice is mailed or otherwise delivered prior to the occurrence of a Change of Control as described below) in the event that the occurrence of the Change of Control is delayed (the “Change of Control Payment Date”);

(iii) that any Security not properly tendered will remain outstanding and continue to accrue interest;

(iv) that unless the Issuer defaults in the payment of the Change of Control Payment, all Securities accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

(v) if such written notice is sent prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional on the occurrence of such Change of Control and shall describe each such condition, and, if applicable, shall state that, in the Issuer’s discretion, the Change of Control Payment Date may be delayed until such time (including more than 60 days after the notice is mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied, or that such redemption may not occur and such notice may be rescinded or amended in the event that the Issuer shall determine that the Change of Control will not occur by the Change of Control Payment Date, or by the Change of Control Payment Date as so delayed;

(vi) that Holders electing to have any Securities purchased pursuant to a Change of Control Offer will be required to surrender such Securities, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Securities completed, to the Paying Agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(vii) that Holders will be entitled to withdraw their tendered Securities and their election to require the Issuer to purchase such Securities, provided that the Paying Agent receives, not later than the close of business on the second Business Day prior to the Change of Control Payment Date, an electronic transmission (PDF), facsimile transmission or letter setting forth the name of the Holder of the Securities with proof of ownership, the principal amount of Securities tendered for purchase, and a statement that such Securities is withdrawing its tendered Securities and its election to have such Securities purchased; and

(viii) the other instructions, as determined by the Issuer, consistent with this Section 4.09, that a Holder must follow.

Securities repurchased by the Issuer pursuant to a Change of Control Offer will either have the status of Securities issued but not outstanding or will be retired and cancelled at the option of the Issuer. Securities purchased by a third party pursuant to the preceding paragraph will have the status of Securities issued and outstanding.

The notice, if sent in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. If (a) the notice is sent in a manner herein provided and (b) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Securities as to all other Holders that properly received such notice without defect.

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase by the Issuer of Securities pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

(1) accept for payment all Securities issued by it or portions thereof properly tendered pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent an amount equal to the aggregate Change of Control Payment in respect of all Securities or portions thereof so tendered; and

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Securities so accepted together with an Officer’s Certificate of the Issuer to the Trustee stating that such Securities or portions thereof have been tendered to and purchased by the Issuer.

(d) The Issuer shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Securities validly tendered and not withdrawn under such Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

(e) In connection with any tender offer for the Securities, including a Change of Control Offer or Asset Sale Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer or any third party making a such tender offer in lieu of the Issuer, purchases all of the Securities validly tendered and not withdrawn by such Holders, the Issuer or such third party will have the right upon not less than 15 days nor more than 60 days prior notice, given not more than 15 days following such purchase date, to redeem all Securities that remain outstanding following such purchase at a redemption price equal to the price offered to each other Holder in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but not including, the Redemption Date.

(f) Other than as specifically provided in this Section 4.09, any purchase pursuant to this Section 4.09 shall be made pursuant to the provisions of Sections 3.04, 3.07 and 3.08 hereof. A Change of Control Offer may be made at the same time as consents are solicited with respect to an amendment, supplement or waiver of this Indenture, the Securities and/or the Guarantees.

SECTION 4.10 Compliance Certificate. The Issuer shall deliver to the Trustee within 120 days after the end of each fiscal year of the Issuer, beginning with the fiscal year ending on or about December 31, 2016, a certificate (the signer of which shall be the principal executive officer, the principal financial officer or the principal accounting officer of the Issuer) stating that in the course of the performance by the signer of the signer’s duties as an Officer of the Issuer the signer would normally have knowledge of any Default and whether or not the signer knows of any Default that occurred during such period. If the signer knows of any such Default, the certificate shall describe such Default.

SECTION 4.11 Further Instruments and Acts. The Issuer shall execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 4.12 Future Subsidiary Guarantors. The Issuer shall not permit (i) any of its Restricted Subsidiaries to guarantee or incur any Indebtedness under the Term Loan Credit Agreement or the Unsecured Notes or (ii) any of its Restricted Subsidiaries that are Domestic Subsidiaries to guarantee or incur any Indebtedness under any other syndicated bank or capital markets Indebtedness of the Issuer or any Restricted Subsidiary in an aggregate principal amount in excess of $50 million, unless, in each case, such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture, the form of which is attached as Exhibit C hereto, providing for a Guarantee by such Restricted Subsidiary of the Securities.

Notwithstanding the foregoing, each such Guarantee may be limited as necessary to recognize certain defenses generally available to guarantors (including those that relate to fraudulent conveyance or transfer, voidable preference, financial assistance, corporate purpose, capital maintenance or similar laws, regulations or defenses affecting the rights of creditors generally) or other considerations under applicable law.

Each Person that becomes a Subsidiary Guarantor after the Issue Date shall also become a party to the applicable Security Documents pursuant to the terms of this Indenture and shall as promptly as practicable, and in no event later than 90 days, 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 that this Indenture provides may be delivered after the Issue Date (to the extent, and substantially in the form, delivered on the Issue Date or the date first delivered, as applicable (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 Notes Priority Collateral and a perfected second-priority security interest (subject to Permitted Liens) in properties and assets that constitute ABL Priority Collateral, as security for such Guarantor’s 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 and the Security Documents 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.

Each Guarantee shall be released in accordance with Section 10.03 hereof.

SECTION 4.13 Liens. The Issuer shall not, and shall not permit any Subsidiary Guarantor to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures Obligations under any Indebtedness or any related guarantee, on any asset or property of the Issuer or any Subsidiary Guarantor, or any income or profits therefrom, or assign or convey any right to receive income therefrom.

The expansion of Liens by virtue of accrual of interest, the accretion of accreted value, the payment of interest or dividends in the form of additional Indebtedness, amortization of original issue discount and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies or increases in the value of property securing Indebtedness will not be deemed to be an incurrence of Liens for purposes of this Section 4.13.

SECTION 4.14 Maintenance of Office or Agency.

(a) The Issuer shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Securities and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee; provided that no service of legal process may be made against the Issuer at any office of the Trustee.

(b) The Issuer may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuer of its obligation to maintain an office or agency for such purposes. The Issuer shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(c) The Issuer hereby designate the Corporate Trust Office of the Trustee or its agent as such office or agency of the Issuer in accordance with Section 2.04 hereof.

SECTION 4.15 Suspension of Certain Covenants.

(a) If, on any date following the Issue Date, (i) the Securities have an Investment Grade Rating from both Rating Agencies and (ii) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”) then, beginning on that day and continuing at all times thereafter until the Reversion Date, as defined below, the Issuer and its Restricted Subsidiaries shall not be subject to Sections 4.03, 4.04, 4.05, 4.06, 4.08, 4.09, 4.12 and clause (iv) of Section 5.01(a) hereof (collectively, the “Suspended Covenants” and each individually, a “Suspended Covenant”). In the event that the Issuer and the Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) (A) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Securities below an Investment Grade Rating, then the Issuer and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events and (B) the Issuer or any of its Affiliates enters into an agreement to effect a transaction that would result in a Change of Control and one or more of the Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Securities below Investment Grade Rating, then the Issuer and the Restricted Subsidiaries will thereafter again be subject to Section 4.09 hereof with respect to future events, including without limitation, the proposed transaction described in this clause (B). The period beginning on the day of a Covenant Suspension Event and ending on a Reversion Date is referred to herein as a “Suspension Period.”

100

On each Reversion Date, all Indebtedness incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period shall be deemed to have been outstanding on the Issue Date, so that it is classified as permitted under Section 4.03(b)(iii) hereof. Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 4.04 hereof shall be made as though Section 4.04 hereof had been in effect prior to, but not during, the Suspension Period. No Default or Event of Default will be deemed to have occurred on the Reversion Date (or thereafter) under any Suspended Covenant solely as a result of any actions taken by the Issuer or its Restricted Subsidiaries, or events occurring, during the Suspension Period. On and after each Reversion Date, the Issuer and its Subsidiaries will be permitted to consummate the transactions contemplated by any contract entered into during the Suspension Period (and not in contemplation of the Reversion Date) so long as such contract and such consummation would have been permitted during such Suspension Period.

(b) For purposes of Section 4.05 hereof, on the Reversion Date, any contractual encumbrances or restrictions of the type specified in clause (a), (b) or (c) of Section 4.05 hereof entered into during the Suspension Period will be deemed to have been in effect on the Issue Date, so that they are permitted under clause (c)(1) of Section 4.05 hereof.

(c) For purposes of Section 4.06 hereof, on the Reversion Date, the unutilized Excess Proceeds amount will be reset to zero.

(d) For purposes of Section 4.08 hereof, any Affiliate Transaction entered into after the Reversion Date pursuant to a contract, agreement, loan, advance or guaranty with, or for the benefit of, any Affiliate of the Issuer entered into during the Suspension Period will be deemed to have been in effect as of the Issue Date for purposes of Section 4.08(b)(vi) hereof. Within 10 days following the Reversion Date any Guarantees released solely upon the related Covenant Suspension Event shall be reinstated and, the Issuer must comply with the terms of Section 4.12 hereof.

(e) During a Suspension Period, the Issuer may not designate any of its Subsidiaries as Unrestricted Subsidiaries pursuant to the second sentence of the definition of “Unrestricted Subsidiaries.”

(f) The Issuer shall deliver promptly to the Trustee an Officer’s Certificate notifying it of the any Suspension Period or any Reversion Date. The Trustee shall have no independent obligation to determine if a Suspension Period has commenced or terminated, to notify the Holders regarding the same or to determine the consequences thereof.

SECTION 4.16 Limited Condition Acquisition; Measuring Compliance

(a) With respect to any (x) acquisition or similar Investment for which the Issuer or any Subsidiary of the Issuer may not terminate its obligations due to a lack of financing for such acquisition or similar Investment (whether by merger, consolidation or other business combination or the acquisition of Capital Stock or otherwise) as applicable or (y) repayment, repurchase or refinancing of Indebtedness with respect to which an irrevocable notice of repayment (or similar irrevocable notice) has been delivered, in each case, for purposes of determining:

(i) whether any Indebtedness (including Acquired Indebtedness) that is being incurred in connection with such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness is permitted to be incurred in compliance with Section 4.03 hereof;

101

(ii) whether any Lien being incurred in connection with such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness or to secure any such Indebtedness is permitted to be incurred in accordance with the covenant described under Section 4.13 hereof or the definition of “Permitted Liens”;

(iii) whether any other transaction undertaken or proposed to be undertaken in connection with such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness complies with the covenants or agreements contained in this Indenture or the Securities; and

(iv) any calculation of the Fixed Charge Coverage Ratio, Consolidated Total Leverage Ratio, Consolidated First Lien Secured Debt Ratio. Consolidated Secured Debt Ratio, Net Income, Consolidated Net Income and/or EBITDA and, whether a Default or Event of Default exists in connection with the foregoing,

at the option of the Issuer, using the date that the definitive agreement for such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness is entered into (the “Transaction Agreement Date”) may be used as the applicable date of determination, as the case may be, in each case with such pro forma adjustments as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed Charge Coverage Ratio” or “EBITDA.” For the avoidance of doubt, if the Issuer elects to use the Transaction Agreement Date as the applicable date of determination in accordance with the foregoing, (a) any fluctuation or change in the Fixed Charge Coverage Ratio, Consolidated Total Leverage Ratio, Consolidated First Lien Secured Debt Ratio, Consolidated Secured Debt Ratio, Net Income, Consolidated Net Income or EBITDA of the Issuer, the target business or assets to be acquired subsequent to the Transaction Agreement Date and at or prior to the consummation of such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness, will not be taken into account for purposes of determining whether any Indebtedness or Lien that is being incurred in connection with such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness is permitted to be incurred or in connection with compliance by the Issuer or any of the Restricted Subsidiaries with any other provision of this Indenture or the Securities or any other transaction undertaken in connection with such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness and (b) until such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness is consummated or such definitive agreements are terminated, such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness and all transactions proposed to be undertaken in connection therewith (including the incurrence of Indebtedness and Liens) will be given pro forma effect when determining compliance of other transactions (including the incurrence of Indebtedness and Liens unrelated to such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness) that are consummated after the Transaction Agreement Date and on or prior to the consummation of such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness and any such transactions (including any incurrence of Indebtedness and the use of proceeds thereof) will be deemed to have occurred

102

on the date the definitive agreements are entered and outstanding thereafter for purposes of calculating any baskets or ratios under this Indenture after the date of such agreement and before the consummation of such acquisition or similar Investment or repayment, repurchase or refinancing of Indebtedness; provided that in connection with the making of Restricted Payments, the calculation of Consolidated Net Income (and any defined term a component of which is Consolidated Net Income) will not, in any case, assume such acquisition or similar Investment has been consummated. In addition, this Indenture will provide that compliance with any requirement relating to absence of Default or Event of Default may be determined as of the Transaction Agreement Date and not as of any later date as would otherwise be required under this Indenture. In the event an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) is incurred or issued, any Lien is incurred or other transaction is undertaken on the same date that any other item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) is incurred or issued, any other Lien is incurred or other transaction is undertaken, then the Fixed Charge Coverage Ratio, Consolidated Total Leverage Ratio, Consolidated First Lien Secured Debt Ratio and Consolidated Secured Debt Ratio will be calculated with respect to such incurrence, issuance or other transaction without regard to any other incurrence, issuance or transaction. Each item of Indebtedness, Disqualified Stock or Preferred Stock that is incurred or issued, each Lien incurred and each other transaction undertaken will be deemed to have been incurred, issued or taken first, to the extent available, pursuant to the relevant Fixed Charge Coverage Ratio, Consolidated Total Leverage Ratio, Consolidated First Lien Secured Debt Ratio and Consolidated Secured Debt Ratio.

SECTION 4.17 After -Acquired Collateral.

(a) From and after the Issue Date, if the Issuer or any Guarantor creates any additional security interest upon any property or asset that would constitute Collateral to secure any Pari Passu Obligations other than the Notes on a first priority basis, or a junior priority basis in the case of ABL Priority Collateral, (subject to Permitted Liens), it shall concurrently grant a first-priority (junior -priority in the case of ABL Priority Collateral) security interest (subject to Permitted Liens) upon such property as security for the Notes and the other Obligations under this Indenture.

(b) The Issuer shall cause each Restricted Subsidiary upon execution and delivery to the Trustee of a supplemental indenture substantially in the form of Exhibit C hereto to become a party to the Security Documents, as applicable, and to execute and file all documents and instruments necessary (as determined by the Issuer) to grant to the Collateral Agent, for the benefit of the Holders, the Trustee and the Collateral Agent, a perfected security interest in the Collateral of such Restricted Subsidiary, in each case solely to the extent required by this Indenture and the Security Documents.

Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Issuer in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Issuer is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the Issuer shall refer instead to the successor corporation and not to the Issuer), and may exercise every right and power of the Issuer under this Indenture with the same effect as if such successor Person had been named as the Issuer herein; provided that the predecessor Issuer shall not be relieved from the obligation to pay the principal of, and interest on the Securities except in the case of a sale, assignment, transfer, lease, conveyance or other disposition of all of the Issuer’s assets that meets the requirements of Section 5.01 hereof.

ARTICLE 6

DEFAULTS AND REMEDIES

SECTION 6.01 Events of Default. An “Event of Default” with respect to the Securities occurs if:

(a) there is a default in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the Securities;

(b) there is a default for 30 days or more in the payment when due of interest on or with respect to the Securities;

106

(c) the Issuer fails for 120 days after receipt of written notice given by the Trustee or the Holders of not less than 30% in principal amount of the Securities to comply with any of its obligations, covenants or agreements described in Section 4.02 hereof;

(d) the Issuer or any Guarantor fails for 60 days after receipt of written notice given by the Trustee or the Holders of not less than 30% in principal amount of the Securities to comply with any of its obligations, covenants or agreements (other than a default referred to in clauses (a), (b) and (c) above) contained in this Indenture or the Securities;

(e) there is a default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Issuer or any of its Restricted Subsidiaries or the payment of which is guaranteed by the Issuer or any of its Restricted Subsidiaries, other than Indebtedness owed to the Issuer or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created after the issuance of the Securities, if both:

(a) such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity; and

(b) the principal amount of such Indebtedness, together with the principal amount of any other such indebtedness in default for failure to pay any principal at its stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $100.0 million or more at any one time outstanding;

(f) the Issuer or any Significant Subsidiary, or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, fails to pay final judgments aggregating in excess of $100.0 million, which final judgments remain unpaid, undischarged, unwaived and unstayed for a period of more than 90 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed;

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

(i) commences a voluntary case;

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

107

(iii) consents to the appointment of a custodian of it or for all or substantially all of its property; or

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

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

(i) is for relief against the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in a proceeding in which the Issuer or any such Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, is to be adjudicated bankrupt or insolvent;

(ii) appoints a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, or for all or substantially all of the property of the Issuer or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary; or

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

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

(i) the Guarantee of any Significant Subsidiary, or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, shall for any reason cease to be in full force and effect or any responsible officer of any Guarantor that is a Significant Subsidiary, or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, as the case may be, denies that it has any further liability under its or their Guarantee(s) or gives notice to such effect, other than by reason of the termination of this Indenture or the release of any such Guarantee in accordance with this Indenture;

(j) unless all the Collateral has been released from the Liens in accordance with the provisions of the Security Documents, the Issuer shall assert or any Guarantor shall assert, in any pleading in a court of competent jurisdiction, that any such security interest is invalid or unenforceable and, in the case of any such Person that is a Subsidiary of the Issuer, the Issuer fails to cause such Subsidiary to rescind such assertions within 30 days after the Issuer has actual knowledge of such assertions; or

108

(k) the failure of the Issuer or any Guarantor to comply for 60 days after receipt of written notice with its other agreements contained in the Security Documents, except for a failure that would not be material to the whole of the Securities and without materially affecting the value of the Collateral taken as a whole.

In the event of any Event of Default specified in clause (e) above, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Securities) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose:

(1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged; or

(2) holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default; or

(3) the default that is the basis for such Event of Default has been cured.

SECTION 6.02 Acceleration. If any Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 6.01 hereof with respect to the Issuer) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 30% in principal amount of the then total outstanding Securities by notice to the Issuer may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Securities to be due and payable immediately. Upon the effectiveness of such declaration, such principal, premium, if any, and interest shall be due and payable immediately.

Notwithstanding the foregoing, in the case of an Event of Default arising under clause (g) or (h) of Section 6.01 hereof with respect to the Issuer, all outstanding Securities shall be due and payable immediately without further action or notice.

The Holders of a majority in aggregate principal amount of the then outstanding Securities by written notice to the Trustee may on behalf of all of the Holders rescind an acceleration and its consequences:

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

(2) if all existing Events of Default have been cured, waived, annulled or rescinded except nonpayment of principal or interest that has become due solely because of the acceleration;

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

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

109

SECTION 6.03 Other Remedies. If an Event of Default with respect to the Securities occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

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

To the extent permitted by the Intercreditor Agreements, the Trustee may direct the Collateral Agent (subject to being directed and indemnified and/or secured to its satisfaction in accordance with this Indenture and the Parity Passu Intercreditor Agreement) to take enforcement action with respect to the Collateral if an Event of Default has occurred and is continuing and the Collateral Agent shall only act under the direction of the Trustee in accordance with the terms hereof (unless this Indenture specifically provides otherwise).

SECTION 6.04 Waiver of Past Defaults. Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of not less than a majority in principal amount of the then outstanding Securities by written notice to the Trustee may on the behalf of all Holders waive an existing Default or Event of Default and its consequences except (a) a continuing Default or Event of Default in the payment of the principal of or interest on a Security, (b) a continuing Default or Event of Default arising from the failure to redeem or purchase any Security when required pursuant to the terms of this Indenture or (c) a Default in respect of a provision that under Section 9.02 hereof cannot be amended without the consent of each Holder affected. When a Default is waived, it is deemed cured and the Issuer, the Trustee and the Holders will be restored to their former positions and rights under this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

SECTION 6.05 Control by Majority. The Holders of a majority in principal amount of the then outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01 hereof, that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.

SECTION 6.06 Limitation on Suits.

(a) Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture or the Securities unless:

110

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

(ii) the Holders of at least 30% in principal amount of the total outstanding Securities have requested the Trustee, in writing, to pursue the remedy;

(iii) such Holders have offered the Trustee security or indemnity satisfactory to it against any loss, liability or expense;

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

(v) Holders of a majority in principal amount of the total outstanding Securities have not given the Trustee a written direction inconsistent with such request within such 60-day period.

(b) 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 such actions or forbearances are unduly prejudicial to such Holders).

SECTION 6.07 Rights of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed or provided for in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

SECTION 6.08 Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) hereof occurs and is continuing with respect to Securities, the Trustee may recover judgment in its own name and as trustee of an express trust against the Issuer or any Guarantor on the Securities for the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at the rate provided for in such Securities) and the amounts provided for in Section 7.07 hereof.

SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for compensation and reasonable expenses, disbursements and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems necessary, advisable or appropriate)) and the Holders of Securities then outstanding allowed in any judicial proceedings relative to the Issuer or any Guarantor, its creditors or its property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing similar functions, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the compensation, and reasonable expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under Section 7.07 hereof.

111

SECTION 6.10 Priorities. Subject to the Intercreditor Agreements, if the Trustee collects any money or property pursuant to this Article 6 or, after an Event of Default, any money or other property distributable in respect of the Issuer’s obligations under this Indenture, it shall pay out the money or property shall be paid out in the following order:

FIRST: to the Trustee acting in any capacity hereunder or in connection herewith (including any predecessor trustee) for amounts due hereunder;

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

THIRD: to the Issuer.

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. At least 15 days before such record date, the Trustee shall send to each Holder and the Issuer a notice that states the record date, the payment date and amount to be paid.

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 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 6.07 hereof or a suit by Holders of more than 10% in principal amount of the Securities.

SECTION 6.12 Waiver of Stay or Extension Laws. Neither the Issuer nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not 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 had been enacted.

112

ARTICLE 7

TRUSTEE

SECTION 7.01 Duties of Trustee.

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

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

(i) the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee (it being agreed that the permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty); and

(ii) the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. The Trustee shall be under no duty to make any investigation as to any statement contained in any such instance, but may accept the same as conclusive evidence of the truth and accuracy of such statement or the correctness of such opinions. However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts, statements, opinions or conclusions stated therein).

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

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

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

SECTION 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

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

(d) The Trustee shall not be liable for any action it takes, suffers or omits to take in good faith which it believes to be authorized or within its discretion, rights or powers conferred upon it by this Indenture; provided, however, that the Trustee’s conduct does not constitute negligence or willful misconduct.

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

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

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

114

(h) The rights, privileges, protections, immunities, indemnifications and benefits given to the Trustee, including its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, the Collateral Agent and each other agent, custodian and other Person employed to act hereunder.

(i) The Trustee shall not be liable for any action taken or omitted by it in good faith at the direction of the Holders of not less than a majority in principal amount of the outstanding Securities as to the time, method and place of conducting any proceedings for any remedy available to the Trustee or the exercising of any power conferred by this Indenture.

(j) Any action taken, or omitted to be taken, by the Trustee in good faith pursuant to this Indenture upon the request or authority or consent of any person who, at the time of making such request or giving such authority or consent, is the Holder of any Security shall be conclusive and binding upon future Holders of Securities and upon Securities executed and delivered in exchange therefor or in place thereof.

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

(m) The Trustee may request that the Issuer delivers a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

(n) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office and such notice references the Securities and this Indenture.

SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee. Any Paying Agent or Registrar may do the same with like rights.

SECTION 7.04 Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, any Guarantee or the Securities, it shall not be accountable for the Issuer’s use of the proceeds from the Securities, and it shall not be responsible for any statement of the Issuer or any Guarantor in this Indenture or in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication. The Trustee shall not be charged with knowledge of any Default or Event of Default unless a Trust Officer of the Trustee shall have received written

115

notice thereof in accordance with Section 12.01 hereof from the Issuer, any Guarantor or any Holder at the Corporate Trust Office of the Trustee. In accepting the trust hereby created, the Trustee acts solely as Trustee for the Holders and not in its individual capacity and all persons, including without limitation the Holders of Securities and the Issuer having any claim against the Trustee arising from this Indenture shall look only to the funds and accounts held by the Trustee hereunder for payment. The Trustee shall not be responsible to make any calculation with respect to any matter under this Indenture. The Trustee shall have no duty to monitor or investigate the Issuer’s compliance with or the breach of, or cause to be performed or observed, any representation, warranty, covenant or agreement of any Person, other than the Trustee, made in this Indenture.

SECTION 7.05 Notice of Defaults. If a Default occurs and is continuing and if it is actually known to a Trust Officer of the Trustee, the Trustee shall send to each Holder notice of the Default within 30 days after it is actually known to a Trust Officer or written notice of it is received by the Trustee, or promptly after discovery or obtaining notice if such discovery is made or notice is received 90 days after the Default occurs. Except in the case of a Default in the payment of principal of, premium (if any) or interest on any Security, the Trustee may withhold the notice if and so long as it in good faith determines that withholding such notice is in the interests of the Holders.

SECTION 7.06 [Intentionally Omitted].

SECTION 7.07 Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time such compensation for its services as shall be agreed in writing between the Issuer and the Trustee. 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 (acting in any capacity hereunder or in connection herewith) upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services, except any such disbursements, advances or expenses as may be attributable to its negligence or willful misconduct as determined by a court of competent jurisdiction. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer and each Guarantor, jointly and severally, shall indemnify the Trustee (acting in any capacity hereunder or in connection herewith) and its officers, directors, employees and agents against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of this trust and the performance of its duties under this Indenture, including the costs and expenses of enforcing this Indenture or Guarantee against the Issuer or a Guarantor (including this Section 7.07) and defending itself against or investigating any claim (whether asserted by the Issuer, any Guarantor, any Holder or any other Person). The obligation to pay such amounts shall survive the payment in full or defeasance of the Securities or the removal or resignation of the Trustee. The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuer shall not relieve the Issuer or any Guarantor of its indemnity obligations hereunder. The Issuer shall defend the claim and the indemnified party shall provide reasonable cooperation at the Issuer’s expense in the defense. Such indemnified parties may have separate counsel and the Issuer and the Guarantors, as applicable, shall pay the fees and expenses of such counsel;

116

provided, however, that the Issuer shall not be required to pay such fees and expenses if they assume such indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no conflict of interest between the Issuer and the Guarantors, as applicable, and such parties in connection with such defense. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct, gross negligence or bad faith as determined by a court of competent jurisdiction.

To secure the Issuer’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of or interest on particular Securities pursuant to Article 8 hereof or otherwise.

The Issuer’s and the Guarantors’ payment obligations pursuant to this Section 7.07 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any Bankruptcy Law or the resignation or removal of the Trustee. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(g) or (h) hereof with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if adequate indemnity against such risk or liability is not assured to its satisfaction.

“Trustee” for purposes of this Section 7.07 shall include any predecessor Trustee; provided, however, that the negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

SECTION 7.08 Replacement of Trustee.

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

(b) The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in aggregate principal amount of the then outstanding Securities may remove the Trustee by so notifying the Trustee and the Issuer in writing (not less than 30 days prior to the effective date of such removal), and may appoint a successor Trustee. The Issuer shall remove the Trustee if:

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

(ii) a receiver or other public officer takes charge of the Trustee or its property; or

117

(iii) the Trustee otherwise becomes incapable of acting.

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

(d) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the Lien provided for in Section 7.07 hereof.

(e) If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of at least 10% in aggregate principal amount of the then outstanding Securities may petition at the expense of the Issuer any court of competent jurisdiction for the appointment of a successor Trustee.

(f) The Issuer’s obligations under this Article 7, as applicable, shall survive the termination of this Indenture and the resignation or removal of the Trustee or Collateral Agent, and no resigned or removed Trustee or Collateral Agent shall have any liability or responsibility for the action or inaction of any successor.

SECTION 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any further act shall be the successor Trustee.

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

SECTION 7.10 Tax Payment and Tax Withholding Obligations. In order to comply with applicable tax laws, rules and regulations a foreign financial institution, issuer, trustee, paying agent, holder or other institution is or has agreed to be subject to (“Applicable Law”) related to this Indenture, the Issuer agrees, upon written request by the Trustee, to provide to the Trustee such requested information about such parties and/or transactions (including any modification to the terms of such transactions) so it can determine whether it has any tax related obligations under Applicable Law that the Issuer have in its possession.

ARTICLE 8

DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01 Discharge of Liability on Securities; Defeasance. This Indenture shall be discharged and shall cease to be of further effect as to all outstanding Securities when:

(a) either (i) all Securities theretofore authenticated and delivered, except lost, stolen or destroyed Securities which have been replaced or paid and Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from trust, have been delivered to the Trustee for cancellation; or (ii) all Securities not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise, will become due and payable within one year or are to be called for redemption within one year under 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 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, Government Securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Securities not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to, but not including, the date of maturity or redemption together with irrevocable instructions from the Issuer to the Trustee to apply the deposited money toward the payment of the Securities at maturity or the redemption date, as the case may be (in connection with any deposit of Government Securities, the Trustee shall receive an opinion from a national recognized firm of independent public accountants confirming the sufficiency of any amounts deposited with the Trustee or paying agent); provided, (i) upon any redemption that requires the payment of the Applicable Premium, the amount deposited will be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the Applicable Premium calculated as of the date of the notice of redemption, with any Applicable Premium Deficit only required to be deposited with the Trustee on or prior to the date of redemption and (ii) any Applicable Premium Deficit will be set forth in an Officer’s Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit will be applied toward such redemption;

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

(c) the Issuer has delivered an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to the satisfaction and discharge have been satisfied.

119

Subject to Section 8.02 hereof, the Issuer and the Guarantors may, at their option and at any time, elect to discharge (i) all of their respective obligations under the Securities, the Guarantees and this Indenture (“legal defeasance option”) and cause the release of all Liens on the Collateral granted under the Security Documents (with respect to such Securities) or (ii) its obligations under Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.08, 4.09, 4.10, 4.12 and 4.13 hereof for the benefit of the Holders and the operation of Section 5.01 and Sections 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of the Issuer only), 6.01(h) (with respect to Significant Subsidiaries of the Issuer only) and 6.01(i) hereof (“covenant defeasance option”) for the benefit of the Holders. The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. In the event that the Issuer terminate all of its obligations under the Securities and this Indenture by exercising its legal defeasance option or its covenant defeasance option, the obligations of each Guarantor under its Guarantee of the Securities shall be terminated simultaneously with the termination of such obligations so long as no Securities are then outstanding.

If the Issuer exercise its legal defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default. If the Issuer exercise its covenant defeasance option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c), 6.01(d), 6.01(e), 6.01(f), 6.01(g) (with respect to Significant Subsidiaries of the Issuer only), 6.01(h) (with respect to Significant Subsidiaries of the Issuer only) or 6.01(i) hereof or because of the failure of the Issuer to comply with subclause (a)(iv) of Section 5.01 hereof.

Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

Notwithstanding Section 8.01(a) hereof, the Issuer’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.07, 7.08 hereof and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.07, 8.05 and 8.06 hereof shall survive such satisfaction and discharge.

SECTION 8.02 Conditions to Defeasance.

(a) The Issuer may exercise its legal defeasance option or its covenant defeasance option, in each case, with respect to the Securities only if:

(i) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, in the opinion of a nationally recognized firm of independent public accountants, investment bank or appraisal firm, to pay the principal of, premium, if any, and interest due on the Securities on the stated maturity date or on the redemption date, as the case may be, of such principal, premium, if any, or interest on such Securities (provided that if such redemption is made as provided under Paragraph 5 of the Security, (x) the amount of cash in U.S. dollars, Government Securities, or a combination thereof, that the Issuer must

120

irrevocably deposit or cause to be deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the Issuer must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Applicable Premium as determined on such date) and the Issuer must specify whether such Securities are being defeased to maturity or to a particular redemption date; provided, upon any redemption that requires the payment of the Applicable Premium, the amount deposited will be sufficient for purposes of this Indenture to the extent that an amount is deposited with the Trustee equal to the Applicable Premium calculated as of the date of the notice of redemption, with any deficit as of the date of redemption (any such amount, the “Applicable Premium Deficit”) only required to be deposited with the Trustee on or prior to the date of redemption. Any Applicable Premium Deficit will be set forth in an Officer’s Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit will be applied toward such redemption;

(ii) in the case of legal defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions, (a) the Issuer have received from, or there has been published by, the United States Internal Revenue Service a ruling, or (b) since the issuance of the Securities, there has been a change in the applicable U.S. federal income tax law,

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

(iii) in the case of covenant defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such covenant defeasance and will be subject to such tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred;

(iv) no Default (other than that resulting from borrowing funds to be applied to make such deposit and the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(v) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under the Senior Credit Facilities or any other material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

(vi) the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or any Guarantor or others; and

121

(vii) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the legal defeasance or the covenant defeasance, as the case may be, have been complied with.

Notwithstanding the foregoing, an Opinion of Counsel required by Section 8.02(a)(ii) hereof with respect to legal defeasance need not be delivered if all of the Securities not theretofore delivered to the Trustee for cancellation (x) have become due and payable or (y) will become due and payable at their stated maturity within one year under 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.

(b) Before or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Securities at a future date in accordance with Article 3.

SECTION 8.03 Application of Trust Money. The Trustee shall hold in trust money or Government Securities (including proceeds thereof) deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from Government Securities through each Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities so discharged or defeased.

SECTION 8.04 Repayment to Issuer. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuer upon written request any money or Government Securities held by it as provided in this Article which, in the written opinion of a nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if Government Securities have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article 8.

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

SECTION 8.05 Indemnity for Government Securities. The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited Government Securities or the principal and interest received on such Government Securities.

SECTION 8.06 Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s obligations under

122

this Indenture and the Securities so discharged or defeased shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or any Paying Agent is permitted to apply all such money or Government Securities in accordance with this Article 8; provided, however, that, if the Issuer have made any payment of principal of or interest on any such Securities because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or Government Securities held by the Trustee or any Paying Agent.

ARTICLE 9

AMENDMENTS AND WAIVERS

SECTION 9.01 Without Consent of the Holders. The Issuer, the Guarantors (with respect to a Guarantee or this Indenture to which it is a party) and the Trustee may amend or supplement this Indenture and any Guarantee or the Securities without the consent of any Holder (including, for the avoidance of doubt, any Securities held by Affiliates):

(vi) to add covenants for the benefit of the Holders or to surrender any right or power conferred upon the Issuer or any Guarantor;

(vii) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act (it being agreed that this Indenture need not qualify under the Trust Indenture Act);

(xi) to conform the text of this Indenture, the Guarantees, the Securities, any Security Document or any Intercreditor Agreement to any provision of the Offering Memorandum under the caption “Description of the Notes” to the extent that such provision in the “Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Guarantees, the Securities, any Security Document or any Intercreditor Agreement, as certified by the Issuer (as provided for in an Officer’s Certificate to the Trustee;

(xii) to make certain changes to this Indenture to provide for the issuance of Additional Securities; or

After an amendment under this Section 9.01 becomes effective, the Issuer shall send to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.01.

SECTION 9.02 With Consent of the Holders. Notwithstanding Section 9.01 hereof, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Securities or the Guarantees with the written consent of the Holders of at least a majority in principal amount of the Securities then outstanding voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Securities), in each case other than Securities beneficially owned by the Issuer or its Affiliates (unless such Affiliates are the only beneficial owners of the Securities) and, subject to Sections 6.04 and 6.07 hereof, any past or existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Securities, except a

124

payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Securities or the Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Securities (including Additional Securities, if any) voting as a single class (including consents obtained in connection with the purchase of, or tender offer or exchange offer for, the Securities). Section 2.09 and Section 12.05 hereof shall determine which Securities are considered to be “outstanding” for the purposes of this Section 9.02. However, without the consent of each Holder of an outstanding Security (including, for the avoidance of doubt, any Securities held by Affiliates) affected, an amendment or waiver may not, with respect to any Securities held by a non-consenting Holder:

(i) reduce the principal amount of such Securities whose Holders must consent to an amendment, supplement or waiver;

(ii) reduce the principal of or change the fixed final maturity of any such Security or alter or waive the provisions with respect to the redemption of such Securities (other than provisions relating to Sections 4.06 and 4.09 hereof); provided that any amendment to notice requirements may be made with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding;

(iii) reduce the rate of or change the time for payment of interest on any Security;

(iv) waive a Default in the payment of principal of or premium, if any, or interest on the Securities, except a rescission of acceleration of the Securities by the Holders of at least a majority in aggregate principal amount of the Securities and a waiver of the payment default that resulted from such acceleration, or in respect of a covenant or provision contained in this Indenture or any Guarantee which cannot be amended or modified without the consent of all affected Holders;

(v) make any Security payable in money other than that stated in such Security;

(vi) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of or premium, if any, or interest on the Securities;

(vii) make any change to this Section 9.02;

(viii) impair the contractual right of any Holder under this Indenture to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

(ix) make any change to or modify the ranking of the Securities that would materially adversely affect the Holders;

125

(x) except as expressly permitted by this Indenture, modify the Guarantee of any Significant Subsidiary, or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Issuer), would constitute a Significant Subsidiary, in any manner adverse to the Holders; or

(xi) make any change in the provisions in the Intercreditor Agreements or this Indenture dealing with the application of proceeds of Collateral that would adversely affect the Holders of the Securities.

Additionally, without the consent of Holders of at least 66 2/3% in principal amount of the Securities then outstanding, no such amendment, waiver or modification will release all or substantially all of the Collateral from the Liens securing the Securities and Guarantees.

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 9.02 becomes effective, the Issuer shall promptly send to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02.

Additionally, if the Issuer enters into a new ABL Credit Agreement, the Collateral Agent shall, upon request of the Issuer, enter into a new ABL Intercreditor Agreement without the consent of any Holder. If the Issuer enters into any Junior Lien Obligations, the Collateral Agent, shall, upon request of the Issuer, enter into a customary intercreditor agreement without the consent of any Holder.

SECTION 9.03 Revocation and Effect of Consents and Waivers.

(a) A consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security or portion of the Security if the Trustee receives written notice of revocation delivered in accordance with Section 12.01 hereof before the date on which the Trustee receives an Officer’s Certificate from the Issuer certifying that the requisite principal amount of Securities have consented. After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt by the Issuer or the Trustee of consents by the Holders of the requisite principal amount of securities, (ii) satisfaction of conditions to effectiveness as set forth in this Indenture and any indenture supplemental hereto containing such amendment or waiver and (iii) execution of such amendment or waiver (or supplemental indenture) by the Issuer and the Trustee.

126

(b) The Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding Section 9.03(a) hereof, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after such record date.

SECTION 9.04 Notation on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Issuer may require the Holder to deliver it to the Trustee. The Trustee, at the direction of the Issuer, may place a notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Issuer so determines, the Issuer in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make a notation or to issue a new Security shall not affect the validity of such amendment, supplement or waiver.

SECTION 9.05 Trustee to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment, supplement or waiver the Trustee (and the Collateral Agent, if a party to such amendment, supplement or waiver) shall receive indemnity reasonably satisfactory to it and shall be provided with, and (subject to Section 7.01 hereof) shall be fully protected in conclusively relying upon, an Officer’s Certificate of the Issuer and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and the Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof. Notwithstanding the foregoing, an Opinion of Counsel shall not be required in connection with the addition of a Guarantor under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture (solely for the purpose of adding such Guarantor) to this Indenture, the form of which is attached as Exhibit C hereto.

SECTION 9.06 [Reserved].

SECTION 9.07 Additional Voting Terms; Calculation of Principal Amount. Except as otherwise set forth herein, all Securities issued under this Indenture shall vote and consent separately on all matters as to which any of such Securities may vote. Determinations as to whether Holders of the requisite aggregate principal amount of Securities have concurred in any direction, waiver or consent shall be made in accordance with this Article 9 and Section 2.14 hereof.

127

ARTICLE 10

GUARANTEES

SECTION 10.01 Guarantees.

(a) Each Guarantor hereby jointly and severally, irrevocably and unconditionally guarantees on a senior secured basis (except for Holdings, whose Guarantee shall be on a senior unsecured basis), as a primary obligor and not merely as a surety, to each Holder and the Trustee and their successors and assigns (i) the full and punctual payment when due, whether at maturity, by acceleration or otherwise, of all obligations of the Issuer under this Indenture (including obligations to the Trustee) and the Securities, whether for payment of principal of, premium, if any, or interest on, if any, the Securities and all other monetary obligations of the Issuer under this Indenture and the Securities and (ii) the full and punctual performance within applicable grace periods of all other obligations of the Issuer whether for fees, expenses, indemnification or otherwise under this Indenture and the Securities, on the terms set forth in this Indenture by executing this Indenture (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”).

Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article 10 notwithstanding any extension or renewal of any Guaranteed Obligation.

(b) Each Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations.

(c) Each Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Holder or the Trustee to any security held for payment of the Guaranteed Obligations.

(d) Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06 hereof, the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise.

(e) Subject to Section 10.02 hereof, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment in full of all the Guaranteed Obligations. Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or reorganization of the Issuer or otherwise.

(f) In furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all other monetary obligations of the Issuer to the Trustee.

128

(g) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Trustee in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article 6 for the purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section 10.01.

(h) Each Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01.

Each Guarantor shall promptly execute and deliver such further instruments and do such further acts as may be reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 10.02 Limitation on Liability. Each Subsidiary Guarantor, and by its acceptance of Securities, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that, any term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby guaranteed without rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. Each Subsidiary Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective maximum liability of all the Subsidiary Guarantors at the time of such payment.

SECTION 10.03 Releases.

(a) A Guarantee as to any Subsidiary Guarantor shall be automatically and unconditionally released and discharged upon:

129

(i) any sale, exchange, disposition or transfer (including through consolidation, merger or otherwise) of (a) the Capital Stock of such Subsidiary Guarantor, after which such Subsidiary Guarantor is no longer a Restricted Subsidiary, or (b) all or substantially all the assets of such Subsidiary Guarantor (including to the Issuer or another Subsidiary Guarantor), which sale, exchange, disposition or transfer in each case is not prohibited by Sections 4.04, 4.06 or 5.01 hereof;

(ii) other than as a result of the repayment in full of the Term Loan Credit Agreement, (a) the release, discharge or termination of the guarantee by such Subsidiary Guarantor of the Term Loan Credit Agreement or (b) the release or discharge of such other guarantee that resulted in the creation of such guarantee, in each case except a release, discharge or termination by or as a result of payment under such guarantee;

(iii) the permitted designation of any Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary;

(iv) the consolidation or merger of any Subsidiary Guarantor with and into the Issuer or another Subsidiary Guarantor that is the surviving Person in such consolidation or merger, or upon the liquidation of such Subsidiary Guarantor following the transfer of all of its assets to the Issuer or another Subsidiary Guarantor; or

(v) the Issuer exercising its legal defeasance option or covenant defeasance option as described under Article 8 or the Issuer’s obligations under this Indenture being discharged in accordance with the terms of this Indenture.

(i) Transfer of Beneficial Interests in the Same Global Security. Beneficial interests in any Restricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Security in accordance with the transfer restrictions set forth in the Restricted Securities Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in a Regulation S Global Security may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an Initial Purchaser). A beneficial interest in an Unrestricted Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Security.

Subject to certain restrictions, the Holders of a majority in principal amount of the outstanding Securities are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses that may be caused by taking or not taking such action.

The Issuer is required to deliver to the Trustee, annually, a certificate indicating whether the signer thereof knows of any Default that occurred during the previous year and the Issuer is required, within five Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default.
