If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into the Company or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation or disposed operation 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, merger, consolidation or disposed operation had occurred at the beginning of the applicable four-quarter period (subject to the threshold specified in the previous sentence).

Interest on a Capital Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by the Company to be the rate of interest implicit in such Capital Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, 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 except as set forth in the first paragraph of this definition. 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 Company may designate.

The Notes shall be in minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof.

(ii) If the Issuers are entitled to pay PIK Interest in respect of the Notes, the Issuer may elect (subject to the restrictions contained in the Notes), without the consent of the Holders of the Notes (and without regard to any restrictions or limitations set forth under Section 4.09 hereof), to pay the applicable amount of PIK Interest (in accordance with the requirements contained in the Notes) for such Interest Period in respect of each outstanding Note on the Interest Payment Date in respect of such Interest Period by (y) increasing the outstanding principal amount of Notes by an amount equal to the PIK Interest elected to be paid (rounded up to the nearest whole dollar), and, upon receipt of an Issuer Order, an adjustment shall be made by the Trustee to reflect such increase, with respect to Global Notes, in the “Schedule of Exchanges of Interests in the Global Note”, or (z) issuing additional Notes (the “PIK Notes”) under this Indenture on the same terms and conditions as the Notes with respect to which such PIK Notes are being issued as PIK Interest in an amount equal to the PIK Interest elected to be paid (rounded up to the nearest whole dollar) (in each case of (y) and (z), a “PIK Payment”). The Initial Notes (including any increases thereof as the result of a PIK Payment and any PIK Notes issued as a PIK Payment with respect thereto) and any Additional Notes of the same series (including any increases thereof as the result of a PIK Payment and any PIK Notes issued as a PIK Payment with respect to such Additional Notes) subsequently issued under this Indenture will be treated as a single class for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references to the “principal” or “principal amount” of Notes or of the Notes of any series for all purposes of this Indenture includes any increase in the principal amount of outstanding Notes (including PIK Notes) as a result of a PIK Payment or outstanding Notes of such series (including PIK Notes) as a result of a PIK Payment with respect to the Notes of such series, as applicable. Interest for the first Interest Period commencing on the Issue Date, for the last Interest Period concluding on the Maturity Date of the Notes and in connection with any redemption or repurchase shall be payable entirely in cash.

43

(b) Global Notes. Notes issued in global form shall be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified in the “Schedule of Exchanges of Interests in the Global Note” attached thereto and each shall provide that it shall represent up to the aggregate principal amount of Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Issuers and authenticated by the Trustee as hereinafter provided.

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of the Regulation S Permanent Global Note, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with transfers of interest as hereinafter provided.

(d) Terms. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

The Notes shall be subject to repurchase by the Issuers pursuant to an Asset Sale Offer as provided in Section 4.10 hereof, a Change of Control Offer as provided in Section 4.14 hereof or an Other Last Out Debt Repayment Offer as provided in Section 4.21 hereof. The Notes shall not be redeemable, other than as provided in Article 3.

Additional Notes ranking pari passu with the Initial Notes may be created and issued from time to time by the Issuers without notice to or consent of the Holders and shall be consolidated with and, to the extent the Additional Notes are fungible with the Initial Notes, form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise as the Initial Notes; provided, that the Issuers’ ability to issue Additional Notes shall be subject to the Issuers’ compliance with Section 4.09 hereof and provided further, that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP number, ISIN or Common Code, if applicable. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Indenture.

44

(e) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to transfers of beneficial interests in any Global Notes that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

One Officer of each Issuer shall execute the Notes on behalf of the Issuers by manual or facsimile signature.

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

A Note shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form of Exhibit A attached hereto by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been duly authenticated and delivered under this Indenture.

On the Issue Date, the Trustee shall, upon receipt of an Issuer Order (an “Authentication Order”), authenticate and deliver the Initial Notes. In addition, at any time, from time to time, the Trustee shall upon receipt of an Authentication Order authenticate and deliver (a) any Additional Notes (including any PIK Notes) for an aggregate principal amount specified in such Authentication Order for such Additional Notes (including any PIK Notes) issued hereunder and (b) record increases in the principal amount of the Notes to reflect a PIK Payment or authenticate PIK Notes to reflect a PIK Payment, each upon receipt of an Issuer Order.

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

Section 2.03 Registrar and Paying Agent.

The Issuers shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes (“Note Register”) and of their transfer and exchange. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar without prior notice to any Holder. The Issuers shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuers or any of their Subsidiaries may act as Paying Agent or Registrar.

The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes.

45

The Issuers initially appoint the Trustee to act as the Paying Agent and Registrar for the Notes and to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

The Issuers shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall notify the Trustee of any default by the Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuers or a Subsidiary) shall have no further liability for the money. If the Issuers or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuers, the Trustee shall serve as Paying Agent for the Notes.

Section 2.05 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes and the Issuers shall otherwise comply with Trust Indenture Act Section 312(a).

Section 2.06 Transfer and Exchange.

Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events in (i) or (ii) above and pursuant to Section 2.06(b)(2)(B) and 2.06(c) hereof.

If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee to protect the Trustee and its agents and in the judgment of the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for its expenses in replacing a Note, including the Trustee’s expenses.

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

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

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

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuers, or by any Affiliate of the Issuers, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Issuers or any obligor upon the Notes or any Affiliate of the Issuers or of such other obligor.

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Issuers consider appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

57

Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial holders, respectively, of Notes under this Indenture.

Section 2.11 Cancellation.

The Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes 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 Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of cancelled Notes (subject to the record retention requirement of the Exchange Act) in accordance with its customary procedures. Certification of the disposal of all cancelled Notes shall be delivered to the Issuers upon its written request. The Issuers may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such defaulted interest as provided in this Section 2.12. The Issuers shall fix or cause to be fixed each such special record date and payment date; provided, that no such special record date shall be less than 10 days prior to the related payment date for such defaulted interest. The Issuers shall promptly notify the Trustee of such special record date and payment date. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) shall send or cause to be sent to each Holder a notice at his or her address as it appears in the Note Register that states the special record date, the related payment date and the amount of such interest to be paid.

Subject to the foregoing provisions of this Section 2.12 and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 2.13 CUSIP and ISIN Numbers.

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

Section 3.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, such Notes shall be selected for redemption by the Trustee (1) if the Notes are listed on an exchange and such listing is known to the Trustee, in compliance with the requirements of such exchange or in the case of Global Notes, in accordance with customary procedures of the Depositary or (2) on a pro rata basis to the extent practicable, or, if the pro rata basis is not practicable for any reason, by lot or by such other method as most nearly approximates a pro rata basis subject to customary procedures of the Depositary. Such Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 10 nor more than 60 days prior to the Redemption Date from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Issuers in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in minimum amounts of $1.00 or an integral multiple of $1.00 in excess thereof. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

The Trustee shall not be responsible for any actions taken or not taken by DTC pursuant to its Applicable Procedures.

Section 3.03 Notice of Redemption.

Subject to Section 3.09 hereof, the Issuers shall deliver notices of redemption electronically or by first-class mail, postage prepaid, at least 15 but not more than 60 days before the purchase or Redemption Date to each Holder of Notes (with a copy to the Trustee) at such Holder’s registered address or otherwise in accordance with the procedures of DTC, except that redemption notices may be delivered electronically or mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 11 hereof. Notices of redemption may be conditional.

The notice shall identify the Notes to be redeemed and shall state:

(a) the Redemption Date;

59

(b) the redemption price;

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent not redeemed shall be issued in the name of the Holder of the Notes upon cancellation of the original Note;

(d) the name and address of the Paying Agent;

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(f) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date;

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

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

(i) any condition to such redemption.

At the Issuers’ request, the Trustee shall give the notice of redemption in the Issuers’ names and at their expense; provided that the Issuers shall have delivered written notice to the Trustee, at least two Business Days prior to the date on which notice of redemption is to be sent (unless a shorter notice shall be agreed to by the Trustee) in the form of an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price, unless such redemption is conditioned on the happening of a future event. 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. In any case, failure to give such notice or any defect in the notice to the Holder of any Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption.

Section 3.05 Deposit of Redemption or Purchase Price.

Prior to noon (Eastern time) on the redemption or purchase date, the Issuers shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased.

60

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after a Record Date but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the redemption or purchase date shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for redemption or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Definitive Note that is redeemed or purchased in part, the Issuers shall issue and the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided, that each new Note shall be in a principal amount of $1.00 or an integral multiple of $1.00 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new Note.

Section 3.07 Optional Redemption.

(e) Notwithstanding this Section 3.07, in connection with any tender offer for all of the outstanding Notes at such time, including a Change of Control Offer or Asset Sale Offer, if Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer and the Issuers, or any third party making such a tender offer in lieu of the Issuers, purchase all of the Notes validly tendered and not withdrawn by such Holders, the Issuers or such third party will have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase date, to redeem all Notes that remain outstanding following such purchase at a redemption price equal to the price offered to each other Holder (excluding any early tender or incentive fee) 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 applicable Redemption Date.

(f) Any notice of any redemption may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuers’ discretion, be subject to one or more conditions precedent, including, without limitation, the consummation of an incurrence or issuance of debt or equity or a Change of Control or other corporate transaction. If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuers’ discretion, the Redemption Date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. In addition, the Issuers may provide in such notice that payment of the redemption price and performance of the Issuers’ obligations with respect to such redemption may be performed by another Person.

(g) If the optional Redemption Date is on or after a Record Date and on or before the corresponding Interest Payment Date, the accrued and unpaid interest, if any, to, but not including, the Redemption Date will be paid on the Redemption Date to the Holder in whose name the Note is registered at the close of business on such Record Date in accordance with the applicable procedures of DTC, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Issuers.

(h) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof and shall be subject to any applicable limitations set forth in the Intercreditor Agreement and the Revolving Loan Credit Agreement.

Section 3.08 [Reserved].

(8) that, if the aggregate principal amount of Notes and Pari Passu Indebtedness surrendered by the holders thereof exceeds the Offer Amount, the Company shall select the Notes (while the Notes are in global form pursuant to the procedures of the Depositary) and the Issuers shall select such Pari Passu Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Pari Passu Indebtedness tendered (with such adjustments as may be deemed appropriate by the Issuers so that only Notes in denominations of $1.00 or integral multiples of $1.00 in excess thereof shall be selected); and

(f) The Issuers, the Depositary or the Paying Agent, as the case may be, shall promptly mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes properly tendered by such Holder and accepted by the Issuers for purchase, and the Issuers shall promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, shall authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate and mail or deliver such new Note) in a principal amount equal to any unpurchased portion of the Note surrendered representing the same indebtedness to the extent not repurchased; provided, that each such new Note shall be in a minimum denomination of $1.00 or an integral multiple of $1.00 in excess thereof. Any Note not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof. The Issuers shall publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Purchase Date.

Other than as specifically provided in this Section 3.09 or Section 4.10 hereof, any purchase pursuant to this Section 3.09 shall be made pursuant to the applicable provisions of Sections 3.01 through 3.06 hereof.

Section 3.10 Redemption for Changes in Taxes.

The Issuers may redeem the Notes, in whole but not in part, at their discretion at any time upon giving not less than 15 nor more than 60 days’ prior notice to the Holders (which notice will be irrevocable and given in accordance with the procedures described under Sections 3.02 and 3.03 hereof), at a redemption price equal to 100.0% of the aggregate principal amount thereof, together with accrued and unpaid interest, if any, to the date fixed by the Issuers for redemption (a “Tax Redemption Date”) and all Additional Amounts (if any) then due and which will become due on the Tax Redemption Date as a result of the redemption or otherwise, if the Issuers or a Guarantor as the case may be, on the next date on which any amount would be payable in respect of the Notes or any Guarantee, is or would be required to pay Additional Amounts, and the Company, Issuers or the relevant Guarantor (but, in the case of a Guarantor, only if the payment giving rise to such requirement cannot be made by the Company, Issuers or another Guarantor, who can make such payment without the obligation to pay Additional Amounts) cannot avoid any such payment obligation by taking reasonable measures available (including making payment through a paying agent located in another jurisdiction), as a result of:

(a) any change in, or amendment to, the laws (or any regulations or rulings promulgated thereunder) of the relevant Tax Jurisdiction affecting taxation which change or amendment has not been formally announced before the date of this Indenture and becomes effective on or after the date of the Indenture (or, if a Tax Jurisdiction has been added since the date of this Indenture, the date on which that Tax Jurisdiction became a Tax Jurisdiction under this Indenture); or

64

(b) any change in, or amendment to, the existing official position regarding the application, administration or interpretation of such laws, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction or a change in published practice), which change, amendment, application or interpretation has not been formally announced before the Issue Date (or, if a Tax Jurisdiction has been added since the Issue Date, the date on which that Tax Jurisdiction became a Tax Jurisdiction under this Indenture).

The Issuers will not give any such notice of redemption earlier than 60 days prior to the earliest date on which the Company, the Issuers or Guarantor, as the case may be, would be obligated to make such payment or withholding if a payment in respect of the Notes or any Guarantee were then due. Prior to the publication or, where relevant, mailing of any notice of redemption of the Notes pursuant to the foregoing, the Issuers will deliver to the Trustee an Opinion of Counsel, to the effect that there has been such change or amendment which would obligate the Company, the Issuers or a Guarantor to make such payment or withholding and an Officer’s Certificate to the effect that the Company, the Issuers or Guarantor, as the case may be, cannot avoid such payment or withholding by taking reasonable measures available to it. For the avoidance of doubt, reasonable measures shall not include anything which has any material impact on the business of the Company, the Issuers or Guarantor, or which would cause the Company, the Issuers or Guarantor to incur any material costs. The Trustee shall be entitled to conclusively rely on such Opinion of Counsel and Officer’s Certificate as sufficient evidence of the conditions as described above, in which event it will be conclusive and binding on all Holders.

The provisions of this Section 3.10 shall apply mutatis mutandis to the laws and official positions of any jurisdiction in which any successor to a payor is organized or otherwise considered to be a resident for tax purposes or any political subdivision or taxing authority or agency thereof or therein. The provisions of this Section 3.10 shall survive any termination, defeasance or discharge of this Indenture.

In addition, to the extent not satisfied by the foregoing, for so long as the Notes remain subject to this Section 4.03(a), the Company shall furnish to Holders thereof and prospective investors in such Notes, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) (as in effect on the Issue Date) of the Securities Act.

Such parent shall not be considered a Guarantor by virtue of providing such guarantee, which may be released at any time. The obligations under this Section 4.03 may be satisfied by having the applicable entity file reports containing the information contemplated hereby within the timeframes contemplated hereunder with the SEC.

Delivery of reports, information and documents to the Trustee hereunder is for informational purposes only and the information and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein, or determinable from information contained therein including the Company or the Issuers’ compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on an Officers’ Certificate).

Section 4.04 Compliance Certificate.

(a) The Issuers shall deliver to the Trustee, within 120 days after the end of each fiscal year ending after the Issue Date, a certificate from the principal executive officer, principal financial officer or principal accounting officer stating that a review of the activities of the Issuers and their Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officer with a view to determining whether the Issuers have kept, observed, performed and fulfilled their obligations under this Indenture, and further stating, as to such Officer signing such certificate, that to the best of his or her knowledge the Issuers have kept, observed, performed and fulfilled each and every condition and covenant contained in this Indenture and are not in default in the performance or observance of any of the terms, provisions, covenants and conditions of this Indenture (or, if a Default shall have occurred, describing all such Defaults of which he or she may have knowledge and what action the Issuers are taking or propose to take with respect thereto).

(b) When any Default has occurred and is continuing under this Indenture, or if the Trustee or the holder of any other evidence of Indebtedness of the Issuers or any Subsidiary gives any notice or takes any other action with respect to a claimed Default, the Company shall promptly (which shall be no more than 30 days upon becoming aware of any Default) deliver to the Trustee by registered or certified mail or by facsimile transmission a statement specifying such event, its status and what action the Company is taking or proposes to take with respect thereto. The Trustee will not be deemed to have knowledge of any Defaults or Events of Default unless written notice of an event, which is in fact a Default, has been delivered to the Trustee by the Company, any Issuer, Guarantor or Holder at the Corporate Trust Office and such notice references the Notes and this Indenture and states that it is a “Notice of Default.”

The Company shall pay, and shall cause each of its Restricted Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate negotiations or proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.06 Stay, Extension and Usury Laws.

For purposes of this Section 4.10 and for no other purpose, the following are deemed to be Cash Equivalents:

(A) any liabilities (as shown on the Company’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto, or if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been shown on the Company’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 Company) of the Company or any Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets (or are otherwise extinguished in connection with the transactions relating to such Asset Sale) and for which the Company and all Restricted Subsidiaries have been validly released;

(B) any securities, notes or other obligations received by the Company or such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into Cash Equivalents (to the extent of the Cash Equivalents received) within 180 days following the closing of such Asset Sale; and

73

(C) any Designated Non-cash Consideration received by the Company or any 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 (C) that is at that time outstanding, not to exceed $5,000,000 for the Reference Period at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

(b) Subject to any applicable limitations set forth in the Intercreditor Agreement and the Revolving Loan Credit Agreement, within 450 days after the later of (x) the date of any Asset Sale and (y) the receipt of such Net Proceeds of any Asset Sale, the Company or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale,

(1) to:

(A) reduce Indebtedness outstanding under a revolving credit facility (including under the Revolving Loan Credit Agreement) to the extent required pursuant to the terms of such revolving credit facility;

(B) permanently reduce Obligations under the Revolving Loan Credit Agreement, and to correspondingly reduce commitments with respect thereto;

(C) permanently reduce Obligations under Pari Passu Indebtedness (and to correspondingly reduce commitments with respect thereto); provided that, in the case of this clause (B), the Company shall equally and ratably reduce Obligations under the Notes on a pro rata basis as provided under Section 3.09 hereof, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount 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 Notes, on a ratable basis with such other Last Out Term Loans or Last Out Incremental Debt, for no less than 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be repurchased (which offer shall be deemed an Asset Sale Offer for purposes of this Indenture); or

(D) permanently reduce Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Company or another Restricted Subsidiary;

(2) 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 Company or a Restricted Subsidiary, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes or continues to constitute a Restricted Subsidiary, (B) Capital Expenditures or (C) acquisitions of other assets that, in each of (A), (B) and (C), either (i) are used or useful in a Similar Business or (ii) replace in whole or in part the businesses or assets that are the subject of such Asset Sale; or

(3) any combination of the foregoing;

provided that, in the case of Section 4.10(b)(2), a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as the Company or such Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds shall be applied to satisfy such commitment within the later of (x) 180 days of such commitment and (y) 450 days after the date of the applicable Asset Sale (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, then such Net Proceeds shall constitute Excess Proceeds after the later of (A) 450 days after the date of the applicable Asset Sale and (B) the termination of such Acceptable Commitment (unless another Acceptable Commitment is entered into with respect thereto prior to such later date).

74

(c) Notwithstanding the foregoing, to the extent that any of or all the Net Proceeds of any Asset Sales by an Exempt Entity would have a material adverse tax consequence to the Issuers, the Company or any of its Restricted Subsidiaries (taking into account any foreign tax credit or benefit actually realized in connection with such repatriation or expatriation) or is prohibited or subject to limitation by applicable local law, order, decree or determination of any arbitrator, court or governmental authority from being repatriated or expatriated to the United States or distributed to the Company or any Guarantor that is not an Exempt Entity, 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 Exempt Entity so long, but only so long, as applicable, as such material adverse tax consequence exists or the applicable local law will not permit repatriation or expatriation to the United States or distribution to the Company or any Guarantor (the Company hereby agreeing to use reasonable efforts to cause the applicable Exempt Entity to take all actions reasonably required by the applicable local law, applicable organizational impediments or other impediment to permit such repatriation, expatriation or distribution), and if such repatriation or expatriation of any of such affected Net Proceeds, as applicable, no longer has material adverse tax consequences or is permitted under the applicable local law, such repatriation or expatriation will be promptly effected and such repatriated or expatriated Net Proceeds will be applied (whether or not repatriation or expatriation actually occurs) in compliance with this Section 4.10.

(d) Any Net Proceeds from an Asset Sale that are not invested or applied as provided and within the time period set forth in Section 4.10(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds an aggregate of $10,000,000 in any fiscal year (the “Excess Proceeds Threshold”), the Company shall make an offer to all Holders and, if and to the extent required by the terms of any Indebtedness that is pari passu in right of payment with the Notes, including, without limitation, the Last Out Term Loans (“Pari Passu Indebtedness”), to the holders of such Pari Passu Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount (or accreted value, as applicable) of the Notes and such Pari Passu Indebtedness that is in a minimum amount of $1.00 or an integral multiple of $1.00 in excess thereof that may be purchased in the amount equal to the sum of the Excess Proceeds (the “Excess Proceeds Payment Amount”) at an offer price in cash in an amount equal to 100% of the principal amount or accreted value thereof, plus accrued and unpaid interest, if any, to, but excluding, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture and, if applicable, the other documents governing the applicable Pari Passu Indebtedness. The Company shall commence an Asset Sale Offer with respect to Excess Proceeds within 15 Business Days after the date that Excess Proceeds exceed the Excess Proceeds Threshold by sending the notice required pursuant to Section 3.09 hereof, with a copy to the Trustee. The Company may satisfy the foregoing obligation with respect to such Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to all or a portion of the available Net Proceeds (the “Advance Portion”) in advance of being required to do so by this Indenture (the “Advance Offer”).

(e) To the extent that the aggregate principal amount (or accreted value, as applicable) of Notes and, if applicable, Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds Payment Amount (or, in the case of an Advance Offer, the Advance Portion), the Company may use any remaining Excess Proceeds (or, in the case of an Advance Offer, the Advance Portion) for such amount offered in any manner not prohibited by this Indenture. If the aggregate principal amount (or accreted value, as applicable) of Notes or the Pari Passu Indebtedness surrendered by such Holders and holders thereof exceeds the amount of Excess Proceeds (or, in the case of an Advance Offer, the Advance Portion), the Company shall select the Notes and such Pari Passu

75

Indebtedness to be purchased on a pro rata basis based on the principal amount or accreted value of the Notes or such Pari Passu Indebtedness tendered with adjustments as necessary so that no Notes or Pari Passu Indebtedness, as the case may be, shall be repurchased in part in an unauthorized denomination. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero, but in the case of an Advance Offer, the amount of Net Proceeds the Company is offering to apply in such Advance Offer shall be excluded in subsequent calculations of Excess Proceeds. Additionally, upon consummation or expiration of any Advance Offer, any remaining Net Proceeds shall not be deemed Excess Proceeds and the Company may use such Net Proceeds for any purpose not otherwise prohibited under this Indenture.

(f) Pending the final application of an amount equal to the Net Proceeds pursuant to this Section 4.10, the holder of such Net Proceeds may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility (including under the Revolving Loan Credit Agreement) or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(g) The Company 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 and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

Section 4.11 Transactions with Affiliates.

(a) The Company shall not, and shall not permit any of its Restricted Subsidiaries to directly or indirectly enter into any transaction (including without limitation any transaction with the Permitted Holdco), including any purchase, sale, lease or exchange of Property, the rendering of any service or the payment of any management, advisory or similar fees (including all guaranties and assumptions of obligations thereof), with (a) any officer, director, holder of any Equity Interests in, or other Affiliate of, the Company, the Issuers or any of their respective Subsidiaries or (b) any Affiliate of any such officer, director or holder involving aggregate payments or consideration in excess of $1,000,000, other than:

(i) transactions existing on the Issue Date;

(ii) transactions between any Issuer or Guarantor and any other Issuer or Guarantor not prohibited hereunder;

(iii) other transactions in the ordinary course of business on terms at least as favorable to the Issuers and Guarantors and their respective Restricted Subsidiaries as would be obtained by it on a comparable arm’s-length transaction with an independent, unrelated third party as determined in good faith by the board of directors (or equivalent governing body) of the Company;

(iv) employment, severance and other similar compensation arrangements (including equity incentive plans and employee benefit plans and arrangements) with their respective officers, directors and employees in the ordinary course of business;

(v) payment of customary fees and reasonable out of pocket costs to, and indemnities for the benefit of, directors, officers and employees of the Company, the Issuers and their respective Restricted Subsidiaries in the ordinary course of business to the extent attributable to the ownership or operation of the Company and its Restricted Subsidiaries;

76

(vi) payments or reimbursements to any Restricted Subsidiary of the Company to fund ordinary course operating costs and expenses, including but not limited to intercompany services, payroll expenses and accrued and unpaid taxes; and

(vii) Restricted Payments (including payments to the Company or its direct or indirect parent) permitted by Section 4.07 hereof.

Section 4.12 Liens.

The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly create, incur, assume or permit to exist any Lien (except Permitted Liens) (each, an “Initial Lien”) that secures Obligations under any Indebtedness or any related Guarantee, on any asset or property of the Company or any of its Restricted Subsidiaries, unless:

(1) in the case of Initial Liens on any Collateral such Lien is a Permitted Lien; or

(2) in the case of any Initial Lien on any asset or property that is not Collateral, (i) the Notes or the Guarantees are equally and ratably secured with (or on a senior basis to, in the case such Initial Lien secured any Subordinated Indebtedness) the Obligations secured by such Initial Lien until such time as such Obligations are no longer secured by such Initial Lien or (ii) such Initial Lien is a Permitted Lien, except that the foregoing shall not apply to Liens securing the Notes and the related Guarantees.

Any Lien created for the benefit of Holders of the Notes in respect of property, assets or proceeds that do not constitute Collateral pursuant to this covenant shall provide by its terms that such Lien will be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

With respect to any Lien securing Indebtedness that was permitted to secure such Indebtedness at the time of the incurrence of such Indebtedness, such Lien shall also be permitted to secure any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion 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 or increases in the value of property securing Indebtedness.

Section 4.13 Corporate Existence.

Except as otherwise provided in Article 5 and Section 10.06 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its existence, corporate, partnership, limited liability company or otherwise, and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Issuers and each Restricted Subsidiary; provided, however, that the Company shall not be required to preserve any such right, license or franchise or the corporate, partnership, or other existence of any of its Restricted Subsidiaries, where the failure to do so would not reasonably be expected to result in a Material Adverse Effect.

77

Section 4.14 Offer to Repurchase Upon Change of Control.

(a) If a Change of Control occurs, unless the Issuers have previously or substantially concurrently therewith delivered a redemption notice with respect to all the outstanding Notes as described under Section 3.07 hereof and clause (e) of this Section 4.14, the Issuers shall make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101.0% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to, but not including, the date of purchase. Within 30 days following any Change of Control, the Issuers shall send notice of such Change of Control Offer by electronic delivery in accordance with the procedures of DTC or first-class mail, with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the security register or otherwise in accordance with DTC’s applicable procedures, with the following information:

(1) that a Change of Control Offer is being made pursuant to this covenant, and that all Notes properly tendered pursuant to such Change of Control Offer shall be accepted for payment by the Issuers;

(2) the purchase price and the purchase date, which shall be no earlier than 15 days nor later than 60 days from the date such notice is delivered except in the case of a conditional Change of Control Offer made in advance of a Change of Control as described below (the “Change of Control Payment Date”);

(3) that any Note not properly tendered shall remain outstanding and continue to accrue interest;

(4) that unless the Issuers default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date;

(5) that Holders shall be entitled to withdraw their tendered Notes and their election to require the Issuers to purchase such Notes; provided that the Paying Agent receives, not later than the close of business on the second Business Day prior to the expiration date of the Change of Control Offer, a facsimile transmission, electronic transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(6) that Holders whose Notes are being purchased only in part shall be issued new Notes and such new Notes shall be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must be equal to at least $1.00 or any integral multiple of $1.00 in excess thereof;

(7) if such notice is delivered 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 describing each such condition; and

(8) the other instructions, as determined by the Issuers, consistent with this Section 4.14, that a Holder must follow.

To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Issuers comply with the applicable securities laws and regulations, then the Issuers shall not be deemed to have breached their obligations under this Section 4.14 by virtue thereof.

78

(b) On the Change of Control Payment Date, the Issuers shall, to the extent permitted by law,

(1) accept for payment all Notes 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 Notes or portions thereof so tendered, and

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

(c) The Issuers 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 Section 4.14 applicable to a Change of Control Offer made by the Issuers and purchases all Notes 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.

(d) Other than as specifically provided in this Section 4.14, any purchase pursuant to this Section 4.14 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06 hereof.

(e) Notwithstanding the foregoing, the Issuers (or their successor following such Change of Control transaction) may elect, within 120 days following the consummation of such Change of Control, to redeem for cash all (and not less than all) of the outstanding Notes at a redemption price equal to, if the redemption is (x) prior to (but not including) the second anniversary of the Issue Date, the sum of (1) 101% of the principal amount of the Notes to be redeemed, plus (2) accrued and unpaid interest, if any, to, but excluding, the Redemption Date; or (y) after the second anniversary of the Issue Date, the applicable redemption price.

Section 4.15 Limitation on Guarantees of Indebtedness by Restricted Subsidiaries.

The Company shall not permit any of its Wholly Owned Subsidiaries (and non-Wholly Owned Subsidiaries if such non-Wholly Owned Subsidiaries guarantee, or are a co-issuer of, other capital markets debt securities of the Company or any Restricted Subsidiary or guarantee all or a portion of, or are a co-borrower under, the Senior Credit Facilities) that are Restricted Subsidiaries, other than a Guarantor, to Guarantee the payment of any Indebtedness of the Company, the Issuers or any Guarantor, unless such Restricted Subsidiary within 15 days (i) executes and delivers a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Company, the Issuers or any Guarantor, if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s Guarantee of the Notes and (ii) executes and delivers a supplement or joinder to the Security Documents or new Security Documents and takes all actions required thereunder to perfect the Liens created thereunder; provided that if such

79

Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee with respect to the Notes substantially to the same extent as such Indebtedness is subordinated to the Notes or such Guarantor’s Guarantee of the Notes; provided that this Section 4.15 shall not be applicable in the event that the Guarantee of the Company’s obligations under the Notes or this Indenture by such Subsidiary would not be permitted under Applicable Law.

The Company may elect, in its sole discretion, to cause any Subsidiary that is not otherwise required to be a Guarantor to become a Guarantor, in which case, such Subsidiary shall not be required to comply with the 15-day period described above and such Guarantee may be released at any time in the Company’s sole discretion so long as any Indebtedness of such Subsidiary then outstanding could have been incurred by such Subsidiary (either (x) when so incurred or (y) at the time of the release of such Guarantee) assuming such Subsidiary were not a Guarantor at such time.

Section 4.16 Discharge and Suspension of Covenants.

(a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from two Rating Agencies (“Investment Grade Status”), and (ii) no Event of 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”), the Company and its Restricted Subsidiaries will not be subject to Section 4.07 hereof, Section 4.08 hereof, Section 4.09 hereof, Section 4.10 hereof, Section 4.11 hereof, Section 4.14 hereof, Section 4.15 hereof, Section 4.18 hereof, Section 4.20 hereof, Section 4.21 hereof, Section 4.22 hereof and clause (3) of Section 5.01(a) hereof (collectively, the “Suspended Covenants”).

(b) In the event that the Company and its Restricted Subsidiaries are not subject to the Suspended Covenants hereunder for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) the Notes cease to have such Investment Grade Status, then the Company and its Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events. The period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to in this Section 4.16 as the “Suspension Period.” Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds shall be reset to zero.

(c) Notwithstanding the foregoing, in the event of any such reinstatement, no action taken or omitted to be taken by the Company or any of its Restricted Subsidiaries or events occurring prior to such reinstatement shall give rise to a Default or Event of Default hereunder with respect to the Notes; provided that (1) with respect to Restricted Payments made after any such reinstatement, the amount available to be made as Restricted Payments shall be calculated as though Section 4.07 hereof had been in effect prior to, but not during the Suspension Period, provided that any Subsidiaries designated as Unrestricted Subsidiaries during the Suspension Period shall automatically become Restricted Subsidiaries on the Reversion Date (subject to the Company’s right to subsequently designate them as Unrestricted Subsidiaries in compliance with the covenants set forth below), (2) all Indebtedness incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period shall be classified as having been incurred or issued as of the Issue Date pursuant to clauses (i), (ii) and (iii) of Section 4.09(b) hereof, (3) any Affiliate Transaction entered into after the Reversion Date pursuant to an agreement entered into during any Suspension Period shall be deemed to be permitted pursuant to clause (i) of Section 4.11(a) hereof and (4) any encumbrance or restriction on the ability of any Non-Guarantor Subsidiary to take any action described in clauses (1) through (3) of Section 4.08 hereof that becomes effective during any Suspension Period shall be deemed to be permitted pursuant to Section 4.08(a) hereof. No default or Event of Default will be deemed to have occurred on the Reversion Date as a result of any actions taken by the Company or its Restricted Subsidiaries during the Suspension Period.

80

(d) On and after each Reversion Date, the Company and its Subsidiaries shall be permitted to consummate the transactions contemplated by any contract entered into during the Suspension Period, so long as such contract and such consummation would have been permitted during such Suspension Period.

(e) The Issuers shall deliver promptly to the Trustee an Officer’s Certificate notifying it of any such occurrence under this Section 4.16.

(f) The Trustee shall have no duty to monitor the ratings of the Notes, determine whether a Covenant Suspension Event or Reversion Date has occurred or notify Holders of the same.

Section 4.17 Additional Amounts.

(a) All payments made by or on behalf of the Issuers or a Successor Issuer under or with respect to the Notes (whether or not in the form of Definitive Notes) or any of the Guarantors on their Guarantee (including in each case any Successor Person) shall be made without withholding or deduction for, or on account of, any present or future taxes, unless the withholding or deduction of such taxes is then required by law. If any deduction or withholding for, or on account of, any taxes imposed or levied by or on behalf of any jurisdiction in which the Issuers or any Guarantor (including in either case any Successor Issuer or Successor Person, as applicable) is incorporated, organized, carrying on a business through a branch, agency or permanent establishment or resident for tax purposes or any political subdivision thereof or therein or any jurisdiction by or through which payment is made by or on behalf of the Issuers or any Guarantor (including in either case any Successor Issuer or Successor Person, as applicable) under or with respect to the Notes or Guarantees or any political subdivision thereof or therein (each, a “Tax Jurisdiction”) will at any time be required to be made from any payments made by or on behalf of the Issuers or Successor Issuers under or with respect to the Notes or any of the Guarantors or Successor Persons with respect to any Guarantee, including payments of principal, redemption price, purchase price, interest or premium, the Issuers or the relevant Guarantor (including in either case any Successor Issuer or Successor Person), as applicable, shall pay such additional amounts (the “Additional Amounts”) as may be necessary in order that the net amounts received by each holder in respect of such payments after such withholding or deduction (including any such deduction or withholding from such Additional Amounts) will equal the respective amounts that would have been received by each holder in respect of such payments in the absence of such withholding or deduction; provided, however, that no Additional Amounts will be payable with respect to:

(i) any taxes to the extent such taxes would not have been imposed but for the Holder or the beneficial owner of the Notes (or a fiduciary, settlor, beneficiary, partner of, member or shareholder of, or possessor of a power over, the relevant Holder, if the relevant Holder is an estate, trust, nominee, partnership, limited liability company or corporation) being or having been a citizen or resident or national of, incorporated, present, or engaged in a trade or business in, or having or having had a permanent establishment in, the relevant Tax Jurisdiction in which such taxes are imposed or having any other (actual or deemed) present or former connection with the relevant Tax Jurisdiction other than by the acquisition or holding of, exercise or enforcement of rights under, or the receipt of payments in respect of, the Notes, this Indenture or any Guarantee;

81

(ii) any taxes to the extent such taxes are imposed or withheld as a result of the failure of the Holder or beneficial owner of the Notes to comply with any written request, made at least 30 days before any such withholding or deduction would be payable, by the Issuers or any of the Guarantors (including in either case any Successor Issuer or Successor Person, as applicable) to provide timely and accurate information concerning the nationality, residence or identity of such Holder or beneficial owner or to make any valid or timely declaration or similar claim or satisfy any certification, information or other reporting requirement, which is required or imposed by a statute, treaty, regulation or administrative practice of the relevant Tax Jurisdiction as a precondition to exemption from all or part of, or reduction in the rate of deduction or withholding of, such taxes (in each case, to the extent such Holder or beneficial owner is legally entitled to do so);

(iii) any taxes imposed or withheld as a result of the presentation of any Note for payment (where Notes are in the form of Definitive Notes and presentation is required) more than 30 days after the relevant payment is first made available for payment to the Holder (except to the extent that the Holder or beneficial owner would have been entitled to Additional Amounts had the Note been presented on the last day of such 30 day period);

(iv) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or excise taxes;

(v) any taxes payable otherwise than by deduction or withholding on or in respect of any Note or Guarantee;

(vi) any taxes that were imposed with respect to any payment on a Note to any Holder who is a fiduciary or partnership or person other than the sole beneficial owner of such payment to the extent that no Additional Amounts would have been payable had the beneficial owner of the applicable Notes been the Holder of such Note;

(vii) any taxes that are imposed or withheld pursuant to Sections 1471 through 1474 of the Code, as of the issue date (or any amended or successor version of such sections), any regulations promulgated thereunder, any official interpretations thereof, any similar law or regulation adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States with respect to the foregoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code;

(viii) any taxes imposed in connection with a Note presented for payment by or on behalf of a Holder or beneficial owner of such Note to the extent such taxes could have been avoided by presenting the relevant Note to, or otherwise accepting payment from, another Paying Agent;

(ix) any taxes imposed as a result of the Holder or beneficial owner being or having been (i) a “10-percent shareholder” of the Issuer as defined in Section 871(h)(3) of the Code or any successor provision or (ii) a controlled foreign corporation that is related to the Issuer within the meaning of Section 864(d)(4) of the Code or any successor provision;

(x) any taxes imposed as a result of the Holder or beneficial owner being a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business, as described in Section 881(c)(3)(A) of the Code or any successor provision;

(xi) any Taxes imposed by reason of the Holder’s or beneficial owner’s past or present status as a passive foreign investment company, a controlled foreign corporation, a foreign tax-exempt organization or a personal holding company with respect to the United States or as a corporation that accumulates earnings to avoid U.S. federal income tax;

82

(8) the Guarantee of any Significant Subsidiary shall for any reason cease to be in full force and effect or be declared null and void or any Guarantor that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together (as of the most recent consolidated financial statement of the Company for a fiscal quarter end) would constitute a Significant Subsidiary), as the case may be, denies in writing that it has any further liability under its Guarantee or gives written 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;

(9) with respect to any Collateral, individually or in the aggregate, having a fair market value in excess of $10,000,000, any of the Security Documents ceases to be in full force and effect, or any of the Security Documents ceases to give the Holders of the Notes the Liens purported to be created thereby with the priority contemplated thereby, or any of the Security Documents is declared null and void or the Company or any Guarantor denies in writing that it has any further liability under any Security Document or gives written notice to such effect (in each case other than in accordance with the terms of this Indenture, the Intercreditor Agreement and the Security Documents), except to the extent that any loss of perfection or priority results from the failure of the Collateral Agent to maintain possession of certificates actually delivered to it representing securities pledged under the Security Documents, or otherwise results from an action (but not an omission) constituting gross negligence or willful misconduct on the part of the Trustee or the Collateral Agent, in each case, as determined by a court of competent jurisdiction by final non-appealable judgment; provided, that if a failure of the sort described in this clause (9) is susceptible of cure (including with respect to any loss of Lien priority on material portions of the Collateral), no Event of Default shall arise under this clause (9) with respect thereto until 60 days after notice of such failure shall have been given to the Company by the Trustee or the Holders of at least 25.0% in principal amount of the then outstanding Notes issued under this Indenture (with a copy to the Trustee);

(10) after a Permitted Holdco Event has occurred and for so long as the conditions set forth in the definition of “Permitted Holdco Event” are met, (i) the Permitted Holdco, the Company or any other related party shall fail to comply with the terms of the Permitted Holdco Undertaking or (ii) the Permitted Holdco Undertaking shall cease to be in full force and effect for any reason; or

(11) any Issuer, Guarantor or any Restricted Subsidiary thereof shall default in any material respect in the observance or performance of any other agreement or condition relating to the PCbtH Service Contract or BOP Lease Agreement, or any other event shall occur or condition exist in relation to the PCbtH Service Contract or BOP Lease Agreement, if such default or other event or condition could reasonably be expected to result in a Material Adverse Effect, individually or in the aggregate for all such defaults, events, or conditions.

(b) In the event of any Event of Default specified in clause (4) of Section 6.01(a) hereof, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 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

95

(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 (6) or (7) of Section 6.01(a) hereof) occurs and is continuing under this Indenture, (a) the Trustee by written notice to the Issuers or (b) the Holders of at least 25.0% in aggregate principal amount of the then total outstanding Notes by written notice to the Issuers and Trustee may declare the principal, premium (if any) interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Any time period to cure any actual or alleged Default or Event of Default may be extended or stayed by a court of competent jurisdiction. Upon the effectiveness of such declaration, such principal, premium (if any), interest and any other monetary obligations on all the then outstanding Notes shall be due and payable immediately. The Trustee shall have no obligation to accelerate the Notes.

Notwithstanding the foregoing, in the case of an Event of Default arising under clause (6) or (7) of Section 6.01(a) hereof, all outstanding Notes shall be due and payable immediately without further action or notice.

The Holders of a majority in aggregate principal amount of the then outstanding Notes may, by written notice to the Trustee on behalf of all of the Holders, rescind an acceleration and its consequences; provided, that such rescission would not conflict with any judgment or decree of a court of competent jurisdiction and all existing Events of Default (except nonpayment of principal, interest, or premium (if any) that has become due solely because of the acceleration) have been cured or waived.

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior to their stated maturity, in each case, in respect of any Event of Default under clause (6) or (7) of Section 6.01(a) hereof (each an “Acceleration Event”), the Applicable Premium with respect to an optional redemption of the Notes shall also be due and payable as though the Notes had been optionally redeemed in full at the time of such Acceleration Event and shall constitute part of the Obligations payable to Holders of the Notes in view of the impracticability and extreme difficulty of ascertaining actual damages. By mutual agreement of the parties, the Applicable Premium is a reasonable calculation of each Holder’s loss as a result of any such Acceleration Event. If the Applicable Premium becomes due and payable, it shall be deemed to be principal of the Notes, and interest shall accrue on the full principal amount of the Notes (including the Applicable Premium) from and after the applicable triggering Acceleration Event. Any Applicable Premium payable above shall be deemed to be the liquidated damages sustained by each Holder of the Notes as the result of the acceleration of the Notes, and the Issuers agree that such Applicable Premium is reasonable under the circumstances currently existing. The Applicable Premium shall also be payable in the event the Notes (and/or this Indenture) are satisfied, released or discharged by foreclosure (whether by power of judicial proceeding or otherwise), deed in lieu of foreclosure or by any other similar means. THE ISSUERS EXPRESSLY WAIVE (TO THE FULLEST EXTENT THEY MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE APPLICABLE PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION. Each Issuer expressly agrees (to the fullest extent they may lawfully do so) that: (A) the Applicable Premium is reasonable and the product of an arm’s length transaction between sophisticated parties, ably represented by counsel; (B) the Applicable Premium shall be payable notwithstanding the then prevailing market rates at the time acceleration occurs; (C) there has been a course of conduct between the Holders of the Notes and the Issuers giving specific consideration in this

96

transaction for such agreement to pay the Applicable Premium; and (D) the Issuers shall be estopped hereafter from claiming differently than as agreed to in this paragraph. Each Issuer expressly acknowledges that its agreement to pay the Applicable Premium to the Holders of the Notes as herein described is a material inducement to the Holders to purchase the Notes.

Section 6.03 Other Remedies.

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

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

Section 6.04 Waiver of Past Defaults.

(a) The Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences under this Indenture, except a continuing Default in the payment of interest on, premium, if any, or the principal of any Note held by a non-consenting Holder (including in connection with an Asset Sale Offer, a Change of Control Offer or an Other Last Out Debt Repayment Offer); provided that, subject to Section 6.02 hereof, the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

(b) In the event of any Event of Default specified in clause (4) of Section 6.01(a) above, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 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.

97

Section 6.05 Control by Majority.

Subject to Section 7.01(e) hereof, Holders of a majority in aggregate principal amount of the then total outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or the Collateral Agent or of exercising any trust or power conferred on the Trustee or the Collateral Agent and the Trustee or the Collateral Agent may act at the written direction of the Holders without liability. The Trustee or Collateral Agent, however, may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee or Collateral Agent in personal liability (it being understood that the Trustee has no duty to determine whether any such action is prejudicial to any Holder or beneficial owner of the Notes).

Section 6.06 Limitation on Suits.

Subject to Section 6.07 hereof, no Holder of a Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

(2) Holders of at least 25.0% in aggregate principal amount of the total outstanding Notes have requested the Trustee to pursue the remedy;

(3) Holders of the Notes have offered and, if requested, provide to the Trustee indemnity or security satisfactory to the Trustee against any loss, liability or expense;

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

(5) Holders of a majority in aggregate principal amount of the total outstanding Notes have not given the Trustee a written direction inconsistent with such request within such 60-day period; and

(6) Such action does not violate the Intercreditor Agreement.

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer, a Change of Control Offer or an Other Last Out Debt Repayment Offer), 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)(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

98

Section 6.09 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceedings, the Issuers, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding has been instituted.

Section 6.10 Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.12 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel), the Collateral Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Collateral Agent, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes including the Guarantors), its creditors or its property and shall be entitled and empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their agents and counsel, and any other amounts due the Trustee or Collateral Agent under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent, their agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to

99

receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.13 Priorities.

If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

(1) to the Trustee, the Collateral Agent, their agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

(2) to Holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

(3) to the Issuers or to such party as a court of competent jurisdiction shall direct, including a Guarantor, if applicable.

The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.13.

Section 6.14 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 a 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, 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 6.14 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10.0% in principal amount of the then outstanding Notes.

ARTICLE 7

TRUSTEE

Section 7.01 Duties of Trustee.

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

100

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

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, 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 stated therein).

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

The Trustee and the Collateral Agent need not investigate any fact or matter stated in the resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, direction, approval or other paper or document, but the Trustee and the Collateral Agent, in their discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee or the Collateral Agent shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

101

(b) Before the Trustee or the Collateral Agent acts or refrains from acting, they may require an Officer’s Certificate or an Opinion of Counsel or both. Neither the Trustee nor the Collateral Agent shall be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel.

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

(f) None of the provisions of this Indenture shall require the Trustee or the Collateral Agent to expend or risk their own funds or otherwise to incur any liability, financial or otherwise, in the performance of any of their duties hereunder, or in the exercise of any of their rights or powers if they shall have reasonable grounds for believing that repayment of such funds or security or indemnity satisfactory to them against such risk or liability is not assured to them.

(g) Neither the Trustee nor the Collateral Agent shall be deemed to have notice of any Default or Event of Default unless the Trustee or the Collateral Agent, as applicable, has actual knowledge thereof or unless written notice of any event which is in fact such a Default is received by the Trustee or the Collateral Agent, as applicable, from the Company, any Issuer, Guarantor or Holder at the Corporate Trust Office of the Trustee or Collateral Agent, respectively, and such notice references the Notes and this Indenture.

(h) In no event shall the Trustee or the Collateral Agent 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 or the Collateral Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

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

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. The Collateral Agent and any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

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 or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

If a Default occurs and is continuing and if it is actually known to the Trustee, the Trustee shall send to Holders of Notes a notice of the Default within 90 days after it occurs. Except in the case of a Default relating to the payment of principal, premium, if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. The Trustee shall not be deemed to know of any Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee from the Company, any Issuer, Guarantor or Holder at the Corporate Trust Office of the Trustee.

Section 7.06 Reports by Trustee to Holders of the Notes.

Within 60 days after each April 1, beginning with April 1, 2022, and for so long as Notes remain outstanding, the Trustee shall send to the Holders of the Notes a brief report dated as of such reporting date that complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b)(2). The Trustee shall send all reports as required by Trust Indenture Act Section 313(c).

A copy of each report at the time it is sent to the Holders of Notes shall be mailed to the Issuers and filed with the SEC and each stock exchange on which the Notes are listed in accordance with Trust Indenture Act Section 313(d). The Issuers shall promptly notify the Trustee when the Notes are listed on any stock exchange.

103

Section 7.07 Compensation and Indemnity.

The Issuers shall pay to the Trustee and Collateral Agent from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in writing from time to time. Neither the Trustee’s nor Collateral Agent’s compensation shall be limited by any law on compensation of a trustee of an express trust. The Issuers shall reimburse the Trustee and Collateral Agent promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s and Collateral Agent’s agents and counsel.

The Company, Issuers and the Guarantors, jointly and severally, shall indemnify the Trustee and the Collateral Agent, each of their officers, directors, employees and agents for, and hold the Trustee and Collateral Agent harmless against, any and all loss, damage, claim, liability or expense (including attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture against the Company, Issuers and the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, the Company, Issuers or any Guarantors, or liability in connection with the acceptance, exercise or performance of any of its powers or duties hereunder). The Trustee or Collateral Agent, as applicable, shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee or Collateral Agent, as applicable, to so notify the Issuers shall not relieve the Issuers of their obligations hereunder. The Issuers shall defend the claim and the Trustee and Collateral Agent may have separate counsel and the Issuers shall pay the fees and expenses of such counsel. The Issuers need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee or Collateral Agent through the Trustee’s or Collateral Agent’s, respectively, own willful misconduct or gross negligence, in each case, as determined by a court of competent jurisdiction by final non-appealable judgment.

The obligations of the Company, Issuers and the Guarantors under this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee or Collateral Agent.

To secure the payment obligations of the Company, Issuers and the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

When the Trustee or Collateral Agent incurs expenses or renders services after an Event of Default specified in Section 6.01(a)(6) or (7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

The Trustee shall comply with the provisions of Trust Indenture Act Section 313(b)(2) to the extent applicable.

Section 7.08 Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10 hereof;

104

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

(c) a custodian or public officer takes charge of the Trustee or its property; or

(d) the Trustee becomes incapable of acting.

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

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuers’ expense), the Issuers or the Holders of at least 10.0% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

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

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. 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 send a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided, all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuer’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09 Successor Trustee by Merger, Etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor 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 will succeed to the trusts created by this Indenture, any of the Notes will 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 Notes so authenticated; and in case at that time any of the Notes will not have been authenticated, any successor to the Trustee may authenticate such Notes 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 will have the full force which it is anywhere in the Notes or in this Indenture.

105

Section 7.12 Limitation on Duty of Trustee and Collateral Agent in Respect of Collateral.

(a) Beyond the exercise of reasonable care in the custody thereof, neither the Trustee nor the Collateral Agent shall have any duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and neither the Trustee nor the Collateral Agent shall be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. Each of the Trustee and the Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith.

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Issuers may, at their option and at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture including that of the Guarantors (and the Trustee, on written demand of and at the expense of the Issuers, shall execute such instruments reasonably requested by the Issuers acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(a) the rights of Holders of Notes to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof;

(b) the Issuers’ obligations with respect to Notes concerning issuing temporary Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(c) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuers’ obligations in connection therewith; and

(d) this Section 8.02.

Subject to compliance with this Article 8, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.18, 4.19, 4.20, 4.21 and 4.22 hereof and clauses (3) and (4) of Section 5.01(a) and Sections 5.01(b) and 5.01(d) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in

107

connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(a)(3), 6.01(a)(4), 6.01(a)(5), 6.01(a)(6) (solely with respect to Restricted Subsidiaries that are Significant Subsidiaries), 6.01(a)(7) (solely with respect to Restricted Subsidiaries that are Significant Subsidiaries) and 6.01(a)(8) hereof shall not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes:

(1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest due on the Notes 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 Notes and the Issuers must specify whether such Notes are being defeased to maturity or to a particular Redemption Date;

(2) in the case of Legal Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions,

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

(b) since the issuance of the Notes, 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 of the Notes shall not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and shall be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions, the Holders of the Notes shall not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and shall 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;

108

(4) 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 Issuers or any Guarantor are a party or by which the Issuers or any Guarantor are bound (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

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

(6) the Issuers 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.

Section 8.05 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuers or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon the written request of the Issuers any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Issuers.

Subject to applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Issuers on their request or (if then held by the Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease.

109

Section 8.07 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under the Note Documents shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, that if the Issuers make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

Upon the request of the Issuers and upon receipt by the Trustee and Collateral Agent, if applicable, of the documents described in Section 9.06 hereof, the Trustee and Collateral Agent, if applicable, shall join with the Company, Issuers and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee or Collateral Agent, if applicable, shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties, benefits, privileges, protections, indemnities or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with the addition of a Guarantor under this Indenture upon (i) execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto and (ii) delivery of an Officer’s Certificate complying with the provisions of Sections 9.06, 12.04 and 12.05 hereof.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuers, the Trustee and the Collateral Agent, as applicable, may amend or supplement any Note Documents with the consent of the Holders of at least a majority in principal amount of the Notes (including, for the avoidance of doubt, any increases thereof as the result of a PIK Payment, any PIK Notes and Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any 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 Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including Additional Notes, if any) voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 and Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.02.

Upon the request of the Issuers and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee and Collateral Agent, if applicable, of the documents described in Section 9.06 hereof, the Trustee and Collateral Agent, if applicable, shall join with the Issuers in the execution of such amended or supplemental indenture or amendment or supplement to Note Documents unless such amended or supplemental indenture or amendment or supplement to any Note Documents affects the Trustee’s or Collateral Agent’s own rights, duties, benefits, privileges, protections, indemnities or immunities under this Indenture or otherwise, in which case the Trustee and Collateral Agent, if applicable, may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

112

It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver. It shall be sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to any amendment, supplement or waiver under this Indenture by any Holder given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuers shall send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. The failure to give such notice to all the Holders, or any defect in the notice will not impair or affect the validity of any such amendment, supplement or waiver. Furthermore, by its acceptance of the Notes, each Holder of the Notes is deemed to have consented to the terms of the Intercreditor Agreements and the Security Documents and to have authorized and directed the Trustee and the Collateral Agent, as applicable, to execute, deliver and perform each of the Intercreditor Agreements and Security Documents to which it is a party, binding the Holders to the terms thereof.

Without the consent of each affected Holder of Notes, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal of or change the fixed final maturity of any such Note or alter or waive the provisions with respect to the redemption of such Notes (other than provisions relating to Section 3.09, Section 4.10, Section 4.14 and Section 4.21 hereof to the extent that any such amendment or waiver does not have the effect of reducing the principal of or changing the fixed final maturity of any such Note or altering or waiving the provisions with respect to the redemption of such Notes);

(3) reduce the rate of or change the time for payment of interest on any Note;

(4) waive a Default in the payment of principal of or premium, if any, or interest on the Notes, except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes 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 Holders;

(5) make any Note payable in money other than that stated therein;

(6) 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 Notes;

(7) make any change in these amendment and waiver provisions;

(8) impair the right of any Holder to institute suit for the enforcement of any payment of principal of, or interest on such Holder’s Notes on or after the due dates therefor;

(9) make any change to or modify the ranking of the Notes that would adversely affect the Holders; or

113

(10) except as expressly permitted by this Indenture, modify or release the Guarantees in any manner materially adverse to the Holders of the Notes.

Notwithstanding the foregoing, without the consent of the Holders of at least 66-2/3% in aggregate principal amount of the Notes then outstanding, no amendment or waiver may (A) make any change in any Security Document or the provisions in this Indenture dealing with Collateral or application of trust proceeds of the Collateral with the effect of releasing the Liens on all or substantially all of the Collateral which secure the Obligations in respect of the Notes or (B) change or alter the priority of the Liens securing the Obligations in respect of the Notes in any Collateral in any way materially adverse, taken as a whole, to the Holders, other than, in each case, as provided under the terms of this Indenture, the Security Documents or the Intercreditor Agreement.

Section 9.03 [Reserved].

Section 9.04 Revocation and Effect of Consents.

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

The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, 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 unless the consent of the requisite number of Holders has been obtained.

Section 9.05 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

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

Section 9.06 Trustee to Sign Amendments, Etc.

The Trustee and Collateral Agent, if applicable, shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities, benefits, privileges, protections, indemnities or immunities of the Trustee or Collateral Agent, if applicable. The Issuers may not sign an amendment, supplement or waiver until the board of directors approves it. In executing any amendment, supplement or waiver, the Trustee and Collateral Agent, if applicable, shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 12.04 hereof, an

114

Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture and an Opinion of Counsel stating that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuers and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof. Notwithstanding the foregoing and upon satisfaction of the requirements set forth in the last sentence of Section 9.01 hereof, no Opinion of Counsel shall be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture.

ARTICLE 10

GUARANTEES

Section 10.01 Guarantee.

Subject to this Article 10, each of the Guarantors hereby, jointly and severally irrevocably and unconditionally guarantees, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, the Collateral Agent and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that: (a) the principal of, interest, and premium on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders, the Trustee or the Collateral Agent hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to or any amendment of any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

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

115

Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders, the Trustee and the Collateral Agent, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantees.

Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuers for liquidation or reorganization, should the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuers’ assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to Applicable Law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

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

The Guarantee issued by any Guarantor shall be a general secured senior obligation of such Guarantor and shall be pari passu in right of payment with all existing and future senior Indebtedness of such Guarantor.

Each payment to be made by a Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of 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 Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Applicable Law or to comply with corporate benefit, financial assistance and other laws. Each 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 Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

116

Each Guarantor shall waive any and all of its rights under the existing or future laws of Guernsey, whether by virtue of the droit de division or otherwise, to require that any liability under or in connection with this Indenture be divided or apportioned with any other person or reduced in any manner whatsoever, and whether by virtue of the droit de discussion or otherwise, to require that recourse be had to the assets of any other person before any claim is enforced against it.

Section 10.03 Execution and Delivery.

To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by its President, one of its Vice Presidents, one of its Assistant Vice Presidents or its Chief Financial Officer.

Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Guarantee shall be valid nevertheless.

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

If required by Section 4.15 hereof, the Issuers shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 10, to the extent applicable.

Section 10.04 Subrogation.

Each Guarantor shall be subrogated to all rights of Holders of Notes against the Issuers in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 10.01 hereof; provided, that if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuers under this Indenture or the Notes shall have been paid in full.

Section 10.05 Benefits Acknowledged.

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

Section 10.06 Release of Guarantees.

A Guarantee by a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Issuers or the Trustee is required for the release of such Guarantor’s Guarantee, upon:

(1) (A) any sale, exchange, transfer or other disposition (by merger, amalgamation, consolidation or otherwise) of the Capital Stock of such Guarantor (including any sale, exchange or transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary; or any sale, exchange or transfer of all or substantially all the assets of such Guarantor, in either case which sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture;

(F) solely if such Guarantor does not guarantee Indebtedness (or commitments in respect thereof) (other than the Notes) (for the avoidance of doubt, prior to giving effect to any release pursuant to this clause (F)) immediately prior and during the Suspension Period; provided, that such Guarantee shall be reinstated upon the Reversion Date or, if earlier, the guarantee by such Guarantor of Indebtedness (or commitments in respect thereof) with pari passu lien priority relative to the Notes (for the avoidance of doubt, prior to giving effect to any release pursuant to this clause (F)); and

(G) as described under Article 9 hereof; and

(2) the Issuers delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in this Indenture relating to such transaction have been complied with.

124

objection to any suit, action, or proceeding that may be brought in connection with this Indenture, the Guarantees or the Notes, including such actions, suits or proceedings relating to securities laws of the United States of America or any state thereof, in such courts whether on the grounds of venue, residence or domicile or on the ground that any such suit, action or proceeding has been brought in an inconvenient forum. The Issuers and each Guarantor agree that final judgment in any such suit, action or proceeding brought in such court shall be conclusive and binding upon the Issuers or the Guarantors, as the case may be, and may be enforced in any court to the jurisdiction of which the Issuers or the Guarantors, as the case may be, are subject by a suit upon such judgment. The Issuers and each Guarantor hereby designate and appoint the U.S. Issuer as their authorized agent upon which process may be served in any such action or proceeding that may be instituted in any such court, and agree that service of any process, summons, notice or document by U.S. registered mail addressed to the U.S. Issuer, with written notice of said service to such Person at the address of the U.S. Issuer set forth in Section 12.02 hereof, shall be effective service of process for any such legal action or proceeding brought in any such court.

Section 12.19 Currency Indemnity.

United States dollars are the sole currency (the “Required Currency”) of account and payment for all sums payable by the Issuers or any Guarantor under or in connection with the Notes, this Indenture and the Guarantees, including damages. Any amount with respect to the Notes, this Indenture the Guarantees or the other Note Documents received or recovered in a currency other than the Required Currency, whether as a result of, or the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Issuers or any Guarantor or otherwise by any Holder or by the Trustee or Paying Agent or Collateral Agent, in respect of any sum expressed to be due to it from the Issuers or any Guarantor will only constitute a discharge to the Issuers or any Guarantor to the extent of the Required Currency amount which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so).

If the Required Currency amount is less than the Required Currency amount expressed to be due to the recipient or the Trustee or Paying Agent or Collateral Agent under the Notes, the Issuers and each Guarantor will indemnify such recipient and/or the Trustee or Paying Agent or Collateral Agent against any loss sustained by it as a result. In any event, the Issuers and each Guarantor will indemnify the recipient against the cost of making any such purchase. For the purposes of this currency indemnity provision, it will be prima facie evidence of the matter stated therein, for the Holder of a Note or the Trustee or Paying Agent or Collateral Agent to certify in a manner satisfactory to the Issuers (indicating the sources of information used) the loss it incurred in making any such purchase. These indemnities constitute a separate and independent obligation from the Issuers’ and each Guarantor’s other obligations, will give rise to a separate and independent cause of action, will apply irrespective of any waiver granted by any Holder of a Note or the Trustee or Paying Agent or Collateral Agent (other than a waiver of the indemnities set out herein) and will continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note or to the Trustee or Collateral Agent. For the purposes of determining the amount in a currency other than the Required Currency, such amount shall be determined using the Exchange Rate then in effect.

125

Section 12.20 Waiver of Immunity.

With respect to any proceeding, each party irrevocably waives, to the fullest extent permitted by Applicable Law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in any court of competent jurisdiction, and with respect to any judgment, each party waives any such immunity in any court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such proceeding or judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

Section 13.09 Collateral Agent.

(a) By their acceptance of the Notes, the Holders hereby designate and appoint Wells Fargo Bank, National Association to serve as Collateral Agent and as their collateral agent under this Indenture, the Security Documents and the Intercreditor Agreement, and agree not to assert any claim (including as a result of any conflict of interest) against the Collateral Agent arising from its role as Collateral Agent under the Note Documents, so long as it is acting in accordance with the terms of such Note Documents. Each of the Holders by acceptance of the Notes and the Trustee hereby irrevocably authorizes the Collateral Agent to take such action on their behalf under the provisions of this Indenture, the Security Documents and the Intercreditor Agreement, and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture, the Security Documents and the Intercreditor Agreement, and consents and agrees to the terms of the Intercreditor Agreement, and each Security Document, as the same may be in effect or may be amended, restated, supplemented or otherwise modified from time to time in accordance with their respective terms. Wells Fargo Bank, National Association hereby agrees to serve as Collateral Agent under the Security Documents and the Intercreditor Agreement, and acknowledges that the Collateral Agent agrees to act as such on the express conditions contained in this Section 13.09. The provisions of this Section 13.09 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders nor any of the Grantors shall have any rights as a third party beneficiary of any of the provisions contained herein other than as expressly provided in Section 13.04. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions of this Indenture, the Security Documents and the Intercreditor Agreement, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the Security Documents and the Intercreditor Agreement, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the other Note Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or other fiduciary relationship with the Trustee, any Holder, any Grantor or any other Person, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture, the Security Documents or the Intercreditor Agreement, or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any Applicable Law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) The Collateral Agent may perform any of its duties under this Indenture, the Security Documents or the Intercreditor Agreement, by or through receivers, agents, employees, attorneys-in-fact or through its officers, directors, Affiliates, employees, agents, advisors, and attorneys in fact (collectively, “Related Persons”) and shall be entitled to advice of counsel concerning all matters pertaining to such duties, and shall be entitled to act upon, and shall be fully protected in taking action in reliance upon any advice or opinion given by legal counsel. The Collateral Agent shall not be responsible for the negligence or willful misconduct of any receiver, agent, employee, attorney-in-fact or Related Person that it selects as long as such selection was made in good faith.

(c) None of the Collateral Agent or any of its Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them under or in connection with this Indenture or the transactions contemplated hereby (except to the extent that the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct) or under or in connection with any Security Document or the Intercreditor Agreement, or the transactions contemplated thereby (except to the extent that the foregoing are found by

130

a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct), or (ii) be responsible in any manner to any of the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Company, the Issuers or any Grantor or Affiliate of any Grantor, or any Officer or Related Persons thereof, contained in this Indenture, or any other Note Documents, or in any certificate, report, statement or other document referred to or provided for in, or received by, the Collateral Agent under or in connection with, this Indenture, the Security Documents or the Intercreditor Agreement, or the validity, effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Security Documents or the Intercreditor Agreement, or for any failure of any Grantor or any other party to this Indenture, the Security Documents or the Intercreditor Agreement, to perform its obligations hereunder or thereunder. None of the Collateral Agent or any of its respective Related Persons shall be under any obligation to the Trustee or any Holder to monitor, ascertain or inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture, the Security Documents or the Intercreditor Agreement, or to inspect the properties, books, or records of any Grantor or any Grantor’s Affiliates.

(d) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication, document or conversation (including those by telephone or e-mail) believed by it to be genuine and correct and to have been signed, sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the Issuers or any Grantor), independent accountants and other experts and advisors selected by the Collateral Agent. The Collateral Agent shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper or document. The Collateral Agent shall be fully justified in failing or refusing to take any action under this Indenture, the Security Documents or the Intercreditor Agreement, unless it shall first receive such advice or concurrence of the Trustee or the Holders of a majority in aggregate principal amount of the Notes as it determines, or if there are any Secured Obligations then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent) and, if it so requests, it shall first be indemnified to its satisfaction by the Holders (or holders of Secured Obligations (if applicable)) against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture, the Security Documents or the Intercreditor Agreement, in accordance with a written request, direction, instruction or consent of the Trustee or the Holders of a majority in aggregate principal amount of the then outstanding Notes, or if there are any Secured Obligations then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent) and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders and holders of Secured Obligations (if applicable).

(e) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless a Responsible Officer of the Collateral Agent shall have received written notice from the Trustee or the Issuers referring to this Indenture, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Notes (subject to this Section 13.09 and the terms of the Intercreditor Agreement).

(f) The Collateral Agent may resign at any time by notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture or the Intercreditor Agreement, the

131

Issuers shall appoint a successor Collateral Agent. If no successor Collateral Agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Issuers (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), a successor Collateral Agent. If no successor Collateral Agent is appointed and consented to by the Issuer pursuant to the preceding sentence within thirty (30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor Collateral Agent hereunder, such successor Collateral Agent shall succeed to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” or “Collateral Agent” (as applicable) in the Note Documents shall mean such successor Collateral Agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder, the provisions of this Section 13.09 (and Section 7.07) shall continue to inure to its benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Indenture or the Intercreditor Agreement.

(g) The Collateral Agent shall be authorized to appoint co-Collateral Agents as necessary in its sole discretion. Neither the Collateral Agent nor any of its respective officers, directors, employees or agents or other Related Persons shall be liable to any Grantor or any Noteholder Secured Party for failure to demand, collect or realize upon any of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of its officers, directors, employees, attorneys, representatives or agents shall be responsible for any act or failure to act hereunder, except to the extent such act is found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct.

(h) By their acceptance of the Notes hereunder, the Collateral Agent is authorized and directed by the Holders to (i) enter into the Security Documents to which it is party, whether executed on or after the Issue Date, (ii) enter into the Intercreditor Agreement, (iii) bind the Holders on the terms as set forth in the Security Documents and the Intercreditor Agreement, (iv) make the representations of the Holders set forth in the Security Documents and the Intercreditor Agreement, (v) perform and observe its obligations under the Security Documents and the Intercreditor Agreement and (vi) release any Collateral in accordance with the terms hereof.

(i) If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral or any payments with respect to the Obligations arising under, or relating to, this Indenture, except for any such proceeds or payments received by the Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article 7, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent, such proceeds to be applied by the Collateral Agent pursuant to the terms of this Indenture, the Security Documents and the Intercreditor Agreement.

(j) The Collateral Agent is each Holder’s agent for the purpose of perfecting the Holders’ security interest in assets which, in accordance with Article 9 of the Uniform Commercial Code can be perfected only by possession. Should the Trustee obtain possession of any such Collateral, upon request from the Issuer, the Trustee shall notify the Collateral Agent thereof and promptly shall deliver such Collateral to the Collateral Agent or otherwise deal with such Collateral in accordance with the Collateral Agent’s instructions.

132

(k) The Collateral Agent (and the Trustee) shall have no obligation whatsoever to the Trustee, any of the Holders, or any of the Noteholder Secured Parties to assure that the Collateral exists or is owned by any Grantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Grantor’s property constituting collateral intended to be subject to the Lien and security interest of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture, any Security Document or the Intercreditor Agreement, other than pursuant to the instructions of the Trustee or the Holders of a majority in aggregate principal amount of the Notes or if there are Secured Obligations then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent), or as otherwise provided in the Security Documents or the Intercreditor Agreement, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent shall have no other duty or liability whatsoever to the Trustee, any Holder, or any Noteholder Secured Party as to any of the foregoing.

(l) If the Issuers or any Guarantor (i) incurs any obligations in respect of Secured Obligations at any time when no Intercreditor Agreement is in effect or at any time when Indebtedness constituting Pari Passu Indebtedness entitled to the benefit of an existing Intercreditor Agreement is concurrently retired, and (ii) delivers to the Collateral Agent an Officer’s Certificate so stating and requesting the Collateral Agent to enter into an intercreditor agreement (on substantially the same terms as the Intercreditor Agreement) in favor of a designated agent or representative for the holders of the Secured Obligations so incurred, the Collateral Agent shall (and is hereby authorized and directed to) enter into such Intercreditor Agreement (at the sole expense and cost of the Issuers, including reasonable legal fees and expenses of the Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder. To the extent an intercreditor agreement is already then in existence, if the Issuers or any Guarantor (i) incurs any additional Secured Obligations and (ii) delivers to the Collateral Agent an Officer’s Certificate so stating and requesting the Collateral Agent to enter into a joinder to such intercreditor agreement in favor of a designated agent or representative for the holders of such Secured Obligations, the Collateral Agent shall (and is hereby authorized and directed to) enter into such joinder (at the sole expense and cost of the Issuers, including reasonable legal fees and expenses of the Collateral Agent). If the Issuers or any Guarantor (i) incurs any Obligations in respect of Indebtedness secured by the Collateral with junior lien priority relative to the Notes and the Guarantees at any time when no Intercreditor Agreement is in effect or at any time when Indebtedness constituting Indebtedness secured by the Collateral with junior lien priority relative to the Notes and the Guarantees entitled to the benefit of an existing Intercreditor Agreement is concurrently retired, and (ii) delivers to the Collateral Agent an Officer’s Certificate so stating and requesting the Collateral Agent to enter into an intercreditor agreement (substantially in form of the Intercreditor Agreement attached hereto as Exhibit E) in favor of a designated agent or representative for the holders of the Obligations in respect of Indebtedness secured by the Collateral with junior lien priority relative to the Notes and the Guarantees so incurred, the Collateral Agent shall (and is hereby authorized and directed to) enter into such Intercreditor Agreement (at the sole expense and cost of the Issuers, including reasonable legal fees and expenses of the Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder. To the extent an intercreditor agreement is already then in existence, if the Issuers or any Guarantor (i) incurs any additional Obligations in respect of Indebtedness secured by the Collateral with junior lien priority relative to the Notes and the Guarantees and (ii) delivers to the Collateral Agent an Officer’s Certificate

133

so stating and requesting the Collateral Agent to enter into a joinder to such intercreditor agreement in favor of a designated agent or representative for the holders of such Obligations in respect of Indebtedness secured by the Collateral with junior lien priority relative to the Notes and the Guarantees, the Collateral Agent shall (and is hereby authorized and directed to) enter into such joinder (at the sole expense and cost of the Issuers, including reasonable legal fees and expenses of the Collateral Agent). By its acceptance of the Notes, each Holder shall be deemed to have authorized and directed the Collateral Agent to enter into and perform its obligations under the Intercreditor Agreement.

(m) No provision of this Indenture, the Intercreditor Agreement or any Security Document shall require the Collateral Agent (or 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 thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders (or the Trustee in the case of the Collateral Agent) or, if there are Secured Obligations then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent) unless the Collateral Agent shall have received indemnity satisfactory to the Collateral Agent against potential costs and liabilities incurred by the Collateral Agent relating thereto. Notwithstanding anything to the contrary contained in this Indenture, the Intercreditor Agreement, or the Security Documents, in the event the Collateral Agent is entitled or required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession of the Collateral, the Collateral Agent shall not be required to commence any such action or exercise any remedy or to inspect or conduct any studies of any property under any mortgages or take any such other action if the Collateral Agent has determined that the Collateral Agent may incur personal liability as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances unless the Collateral Agent has received security or indemnity from the Holders (and the holders of Secured Obligations (if applicable)) in an amount and in a form all satisfactory to the Collateral Agent in its sole discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease taking any action described above if it no longer reasonably deems any indemnity, security or undertaking from the Issuers or the Holders (or holders of Secured Obligations (if applicable)) to be sufficient.

(n) The Collateral Agent (i) shall not be liable for any action taken or omitted to be taken by it in connection with this Indenture, the Intercreditor Agreement, or the Security Documents or any instrument referred to herein or therein, except to the extent that any of the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross negligence or willful misconduct, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent may agree in writing with the Issuers (and money held in trust by the Collateral Agent need not be segregated from other funds except to the extent required by law) and (iii) may consult with counsel of its selection and the advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect of any action taken, omitted or suffered by it in good faith and in accordance with the advice or opinion of such counsel. The grant of permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

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

(p) The Collateral Agent does not assume any responsibility for any failure or delay in performance or any breach by the Issuers or any other Grantor under this Indenture, the Intercreditor Agreement, and the Security Documents. The Collateral Agent shall not be responsible to the Holders or any other Person for any recitals, statements, information, representations or warranties contained in any Note Documents or in any certificate, report, statement, or other document referred to or provided for in,

134

or received by the Collateral Agent under or in connection with, this Indenture, the Intercreditor Agreement or any Security Document; the execution, validity, genuineness, effectiveness or enforceability of the Intercreditor Agreement, and any Security Documents as to any other party thereto; the genuineness, enforceability, collectability, value, sufficiency, location or existence of any Collateral, or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority of any Lien therein; the validity, enforceability or collectability of any Obligations; the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any obligor; or for any failure of any obligor to perform its Obligations under this Indenture, the Intercreditor Agreement, and the Security Documents. The Collateral Agent shall have no obligation to any Holder or any other Person to ascertain or inquire into the existence of any Default or Event of Default, the observance or performance by any obligor of any terms of this Indenture, the Intercreditor Agreement, and the Security Documents, or the satisfaction of any conditions precedent contained in this Indenture, the Intercreditor Agreement, and any Security Document. The Collateral Agent shall not be required to initiate or conduct any litigation or collection or other proceeding under this Indenture, the Intercreditor Agreement, and the Security Documents unless expressly set forth hereunder or thereunder or as directed by Holders of a majority in aggregate principal amount of the Notes or, if Secured Obligations are then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent). The Collateral Agent shall have the right at any time to seek instructions from the Holders with respect to the administration of the Note Documents.

(q) The parties hereto and the Holders hereby agree and acknowledge that the Collateral Agent shall not assume, be responsible for or otherwise be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements, damages (including foreseeable and unforeseeable), judgments, expenses and costs (including but not limited to, any remediation, corrective action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or property damages, real or personal) of any kind whatsoever, pursuant to any environmental law as a result of this Indenture, the Intercreditor Agreement, and the Security Documents or any actions taken pursuant hereto or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of its rights under this Indenture, the Intercreditor Agreement, and the Security Documents, the Collateral Agent may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent in the Collateral, including without limitation the properties constituting real property that constitute Collateral, and that any such actions taken by the Collateral Agent shall not be construed as or otherwise constitute any participation in the management of such Collateral, including without limitation the real properties that constitute Collateral, as those terms are defined in Section 101(20)(E) of the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. §§ 9601 et seq., as amended.

(r) Upon the receipt by the Collateral Agent of a written request of the Issuers signed by one Officer of each Issuer (a “Security Document Order”), the Collateral Agent is hereby authorized to execute and enter into, without the further consent of any Holder or the Trustee, any Security Document to be executed after the Issue Date. Such Security Document Order shall (i) state that it is being delivered to the Collateral Agent pursuant to, and is a Security Document Order referred to in, this Section 13.09(r), and (ii) instruct the Collateral Agent to execute and enter into such Security Document. Any such execution of a Security Document shall be at the direction and expense of the Issuer, upon delivery to the Collateral Agent of an Officer’s Certificate and Opinion of Counsel stating that all conditions precedent to the execution and delivery of the Security Document have been satisfied. The Holders, by their acceptance of the Notes, hereby authorize and direct the Collateral Agent to execute such Security Documents.

135

(s) Subject to the provisions of the applicable Security Documents, each Holder, by acceptance of the Notes, agrees that the Collateral Agent shall execute and deliver the Security Documents to which it is a party and all agreements, documents and instruments incidental thereto, and act in accordance with the terms thereof. For the avoidance of doubt, except as expressly set forth herein, in the Security Documents, the Collateral Agent shall have no discretion under this Indenture, the Intercreditor Agreement, or the Security Documents and shall not be required to make or give any determination, consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount of the then outstanding Notes or the Trustee or, if Secured Obligations are then outstanding, the applicable “Authorized Representative” under the Intercreditor Agreement (if other than the Collateral Agent), as applicable.

(t) After the occurrence and during the continuance of an Event of Default and subject to the terms of the Intercreditor Agreement, the Trustee may direct the Collateral Agent in connection with any action required or permitted by this Indenture, the Security Documents and the Intercreditor Agreement.

(u) The Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed under the Security Documents, for turnover to the Trustee to make further distributions of such funds to itself, the Trustee and the Holders in accordance with the provisions of Section 6.13 and the other provisions of this Indenture and the Intercreditor Agreement. The Collateral Agent shall not have any duty to invest any funds that may be on deposit with it under this Indenture or any other Security Document.

(v) In each case that the Collateral Agent may or is required hereunder or under any other Note Document to take any action (an “Action”), including without limitation to make any determination, to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any other Note Document, the Collateral Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. Subject to the terms of the Intercreditor Agreement, if the Collateral Agent shall request direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes with respect to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes, and the Collateral Agent shall not incur liability to any Person by reason of so refraining.

(w) Notwithstanding anything to the contrary in this Indenture or any other Note Document, in no event shall the Collateral Agent (or the Trustee) be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the other Note Documents (including without limitation the filing or continuation of any UCC financing or continuation statements or similar documents or instruments), nor shall the Collateral Agent or the Trustee be responsible for, and the Collateral Agent and the Trustee make no representation regarding, the validity, effectiveness or priority of any of the Security Documents or the security interests or Liens intended to be created thereby. The Collateral Agent makes no representation regarding the validity, effectiveness or enforceability of the Intercreditor Agreement, or any subsequent intercreditor agreement.

(x) Before the Collateral Agent acts or refrains from acting in each case at the request or direction of the Issuers or the Guarantors, or in connection with any Security Document or the Intercreditor Agreement, it may require an Officer’s Certificate and an Opinion of Counsel, which shall conform to the provisions of Section 12.05. The Collateral Agent shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion.

136

(y) Notwithstanding anything to the contrary contained herein but subject to the terms of the Intercreditor Agreement, the Collateral Agent shall act pursuant to the instructions of the Noteholder Secured Parties or the Trustee as provided in this Indenture solely with respect to the Security Documents.

The Collateral Agent shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Collateral Agent to so notify the Issuers shall not relieve the Issuers or any Guarantor of their obligations hereunder. The Issuers and the Guarantors shall defend the claim and the Collateral Agent may have separate counsel and the Issuers and the Guarantors shall pay the reasonable fees and expenses of such counsel. The Issuers and the Guarantors need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Collateral Agent to the extent that the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from the Collateral Agent’s own willful misconduct or gross negligence. The obligations of the Issuers and the Guarantors under this Section 13.09(z) shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Collateral Agent. To secure the payment obligations of the Issuers and the Guarantors in this Section 13.09(z) but subject to the terms of the Collateral Agent shall have a Lien prior to the Notes and rights of the Holders on all money or property held or collected by the Trustee or Collateral Agent, except that held in trust to pay principal, premium, if any, and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. For the avoidance of doubt, the Issuers shall pay compensation to, reimburse expenses of and indemnify the Collateral Agent in accordance with Section 7.07.

1. INTEREST. Diamond Foreign Asset Company an exempted company formed under the laws of the Cayman Islands and a Wholly Owned Subsidiary of the Company (as defined below) (the “Cayman Issuer”), and Diamond Finance, LLC, a limited liability company organized and existing under the laws of the State of Delaware and a Wholly Owned Subsidiary of the Cayman Issuer (the “U.S. Issuer,” together with the Cayman Issuer, the “Issuers”), promise to pay interest on the principal amount of this Note at (a) 9.00% per annum payable in cash, (b) 11.00% per annum with 5.50% of such interest payable in cash and 5.50% of such interest payable in PIK Interest or (c) 13.00% per annum payable in PIK Interest from April 23, 2021 (the “Issue Date”) until maturity. The Issuers will pay interest semi-annually in arrears on April 30 and October 31 of each year; provided, however, that in 2026, the Interest Payment Date will occur on April 22 instead of April 30; provided, further that if any such day is not a Business Day, the Interest Payment Date will on the next succeeding Business Day (each, an “Interest Payment Date”) and no interest shall accrue on such payment as the result of the delay; provided, further that in each case, after the fifth anniversary of the Issue Date, interest shall be payable only at maturity (which interest shall be an amount calculated so that the total amount of interest paid after the fifth anniversary of the Issue Date would equal the amount that would have been paid without the foregoing proviso). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided, that the first Interest Payment Date shall be October 31, 2021. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

2. METHOD OF PAYMENT. The Issuers will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the April 15 or October 16 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest; provided, however, that in 2026, the Record Date will occur on April 7 instead of April 15. Payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, provided, that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuers or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

In the event that the Issuers shall determine to pay PIK Interest, in part or in full, for any Interest Period, then the Issuers shall deliver a notice (a “PIK Notice”) to the Trustee following the Determination Date but prior to the first day of the relevant Interest Period, which notice shall state the total amount of interest to be paid on the Interest Payment Date in respect of such Interest Period. The Trustee, on behalf of and at the expense of the Issuer, shall promptly deliver a corresponding notice provided by the Issuer to the Holders. For the avoidance of doubt, failure to deliver a PIK Notice in

A-5

accordance with the Indenture shall not be an Event of Default. For the avoidance of doubt, interest on the Notes in respect of any Interest Period for which a PIK Notice is not delivered in accordance with the Indenture must be paid entirely in cash. Interest for the last Interest Period ending at the stated maturity of the Notes shall be payable entirely in cash.

If the Issuers are entitled to pay PIK Interest in respect of this Note, the Issuers may elect (subject to the restrictions contained in this Note), without the consent of the Holders of the Notes (and without regard to any restrictions or limitations set forth under Section 4.09 of the Indenture), to pay the applicable amount of PIK Interest (in accordance with the requirements contained in this Note) for such Interest Period in respect of this Note on the Interest Payment Date in respect of such Interest Period by (i) increasing the outstanding principal amount of this Note by an amount equal to the PIK Interest elected to be paid (rounded up to the nearest whole dollar), with respect to Global Notes; and, upon receipt of an Issuer Order, an adjustment shall be made by the Trustee to reflect such increase in the “Schedule of Exchanges of Interests” in the Global Note or (ii) issuing PIK Notes under the Indenture on the same terms and conditions as this Note in an amount equal to the PIK Interest elected to be paid (rounded up to the nearest whole dollar) (in each case of (i) and (ii), a “PIK Payment”). Following an increase in the principal amount of the outstanding Notes as a result of a PIK Payment, the Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued will be dated as of the applicable Interest Payment Date and will bear interest from and after such date. All Notes issued pursuant to a PIK Payment will mature on the same date as the Notes in respect of which such PIK Payment was made as a payment of PIK Interest, and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and will have the same rights and benefits of the Notes in respect of which such PIK Payment was made as a payment of PIK Interest. Any certificated PIK Notes will be issued with the description “PIK” on the face of such PIK Notes.

Reference is hereby made to the Indenture, dated as of April 23, 2021 (the “Indenture”), among Diamond Foreign Asset Company, Diamond Finance, LLC, the Guarantors named therein, the Trustee and the Collateral Agent. Capitalized terms used but not defined herein shall have the meanings given to them in the Indenture.

_______________ (the “Transferor”) owns and proposes to transfer the Note[s] or interest in such Note[s] specified in Annex A hereto, in the principal amount of $___________ in such Note[s] or interests (the “Securities”), to _______________ (the “Transferee”). In connection with the transfer, the Transferee hereby certifies that:

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

B-1-1

2. We understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Issuers or a Subsidiary thereof, (b) pursuant to a registration statement which has been declared effective under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a “QIB”) that purchases for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) to an “Accredited Investor” within the meaning of Rule 501(a) under the Securities Act that is purchasing for its own account or for the account of such an “Accredited Investor,” in each case in a minimum principal amount of Securities of $250,000 or (e) pursuant to any other available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and in compliance with any applicable state securities laws.

WHEREAS, (a) concurrent with the Effective Date, (i) the Parent and Diamond Foreign Asset Company, a Cayman Islands exempted company limited by shares (“DFAC”), as borrower, entered into that certain Credit Agreement dated as of the date hereof (as amended, restated, amended and restated, supplemented, increased, extended or otherwise modified from time to time, the “First Out Revolving Credit Agreement”) by and among the Parent, DFAC, Wells Fargo Bank, National Association, as administrative agent thereunder and as collateral agent, and the lenders and the issuing lenders from time to time party thereto, (ii) the Parent and DFAC, as borrower, entered into that certain Term Loan Agreement dated as of the date hereof (as amended, restated, amended and restated, supplemented, increased, extended or otherwise modified from time to time, the “Last Out Term Loan Agreement”) by and among the Parent, DFAC, as borrower, Wells Fargo Bank, National Association, as administrative agent thereunder and as collateral agent, and the lenders from time to time party thereto, (iii) the Parent, DFAC, as co-issuer, and Diamond Finance, LLC (“Diamond Finance”), as co-issuer, entered into that certain Indenture dated as of the date hereof (as amended, restated, amended and restated, supplemented, increased, extended or otherwise modified from time to time, the “Last Out Notes Indenture” and, together with the First Out Revolving Credit Agreement and the Last Out Term Loan Agreement, the “Facilities Agreements” and, each individually, a “Facility Agreement”) by and among the Parent, the other guarantors party thereto from time to time, DFAC, Diamond Finance, Wilmington Savings Fund Society, FSB, as trustee, the Collateral Agent, and the noteholders from time to time party thereto, (b) subject to the terms and conditions of the Facilities Agreements, certain of the Obligors may enter into one or more Last Out Incremental Debt Documents, each of which shall be secured on an equal and ratable basis with the other Secured Obligations, and (c) concurrent with the Effective Date, the Parent and each other Restricted Subsidiary party thereto, the authorized representatives under each of the Facilities Agreements, and the Collateral Agent entered into that certain Collateral Agency and Intercreditor Agreement, dated as of the date hereof (as amended, restated, amended and restated, supplemented, or otherwise modified from time to time, the “Intercreditor Agreement”; unless otherwise defined herein or the context otherwise requires, capitalized terms used in this Agreement shall have the meanings provided in the Intercreditor Agreement, or if not defined in the Intercreditor Agreement, in the First Out Revolving Credit Agreement).

WHEREAS, the Parent and the other Obligors party hereto in their respective capacities as holders or payees of Indebtedness, liabilities, and other obligations, whether now or hereafter arising, and whether due to or becoming due, absolute or contingent, liquidated or unliquidated, determined or undetermined, including all fees and all other amounts payable in connection with any of the foregoing, owed by any Obligor (collectively, the “Subordinated Debt”), desire to subordinate such Subordinated Debt to the Secured Obligations as set forth below.

WHEREAS, such agreements or understandings governing or evidencing such Subordinated Debt are referred to herein as “Subordinated Intercompany Debt Agreements”.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the Obligors, the Obligors agree as follows:

1. Subordination.

(a) Each Obligor severally covenants and agrees in its respective capacity as holder or payee of any Subordinated Debt, that any Subordinated Debt owed to it, whether now or hereafter existing, is subordinated in right of payment and enforcement, to the extent and in the manner provided in this Section 1, to the prior payment in full in cash of all of the Secured Obligations and that the subordination herein is for the benefit of the Collateral Agent and the other Secured Parties. Each Obligor (with respect to Subordinated Debt owed to it) agrees that, after the occurrence and during the continuation of an Event of Default, such Obligor shall not ask, demand, accelerate, sue for, or take or receive from any other Obligor, directly or indirectly, in cash, securities, or other property or by set-off or in any other manner (including, without limitation, from or by way of collateral), payment of all or any of the Subordinated Debt. Without limitation of the foregoing with respect to any Subordinated Debt, so long as no Event of Default has occurred and is continuing, to the extent permitted under the First Lien Documents, any Obligor may make and any Obligor may receive any (x) payments of principal, interest and any other amounts, including, without limitation, prepayments of principal and (y) refinancings, replacements, renewals or extensions of such Subordinated Debt that are subordinated to the Secured Obligations in accordance with this Section 1; provided, that in the event that any Obligor receives any payment of any such Subordinated Indebtedness at a time when such payment is prohibited by this Section 1, such payment shall be held by such Obligor, in trust for the benefit of, and shall be paid forthwith over and delivered to the Collateral Agent for the benefit of the Secured Parties according to the respective Secured Obligations held or represented by each.

(b) Each Obligor agrees that upon any distribution of assets of any Obligor in any dissolution, winding up, liquidation or reorganization (whether in bankruptcy, insolvency or receivership proceedings or upon an assignment for the benefit of creditors or otherwise): (i) the Collateral Agent and the other Secured Parties shall first be entitled to receive payment in full of the Secured Obligations before any holder or payee of Subordinated Debt is entitled to receive any payment on account of Subordinated Debt, (ii) any payment or distribution of assets of any Obligor of any kind or character, whether in cash, property or securities, to which any such holder or payee of Subordinated Debt would be entitled except for the provisions of this subsection 1(b), shall be paid by the liquidating trustee or agent or other Person making such payment or distribution directly to the Collateral Agent, for the benefit of itself and the other Secured Parties, to the extent necessary to make payment in full of all Secured Obligations remaining unpaid after giving effect

2

to any concurrent payment or distribution or provisions therefor to Collateral Agent, for itself and the other Secured Parties in accordance with the Intercreditor Agreement, (iii) in the event that, notwithstanding the foregoing provisions of this subsection 1(b), any such payment or distribution described in the foregoing subclause (i) or (ii) shall be received by any Obligor on account of Subordinated Debt during the term of this Agreement, such payment or distribution shall be received and held in trust for and shall be paid over to the Collateral Agent, for application to the payment of the Secured Obligations, after giving effect to any concurrent payment or distribution or provision therefor to the Collateral Agent and (iv) no right of the Collateral Agent or any other Secured Parties to enforce the subordination provisions herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of a Credit Party or any Obligor. If, for any reason, any of the trusts expressed to be created in this Section 1 should fail or be unenforceable, the affected Obligor will promptly pay or distribute any such payment or distribution of assets to the Collateral Agent, for application to the payment of the Secured Obligations in accordance with the Intercreditor Agreement.

2. Authorization to Collateral Agent. If, while any Subordinated Debt is outstanding, any insolvency proceeding shall occur and be continuing with respect to any Obligor or its property: (a) the Collateral Agent hereby is irrevocably authorized and empowered (in the name of each Obligor or otherwise), but shall have no obligation, to ask, demand, accelerate, sue for, collect, and receive every payment or distribution in respect of the Subordinated Debt and give acquittance therefor and to file claims and proofs of claim and take such other action (including voting the Subordinated Debt) as it may deem necessary or advisable for the exercise or enforcement of any of the rights or interests of the Collateral Agent and the other Secured Parties; and (b) each Obligor shall promptly take such action as the Collateral Agent reasonably may request (i) to collect the Subordinated Debt for the account of the Collateral Agent and the other Secured Parties and to file appropriate claims or proofs of claim in respect of the Subordinated Debt, (ii) to execute and deliver to the Collateral Agent such powers of attorney, assignments, and other instruments as it may request to enable it to enforce any and all claims with respect to the Subordinated Debt, and (iii) to collect and receive any and all payments in respect of Subordinated Debt.

3. No Enforcement of Remedies; No Contest of Enforcement or Forbearance. Each Obligor agrees that such Obligor shall not (a) exercise or enforce any creditors’ rights or remedies that it may have against any Obligor, or foreclose, repossess, sequester, or otherwise institute any action or proceeding (whether judicial or otherwise, including the commencement of any insolvency proceeding) to enforce any Subordinated Debt, unless the Collateral Agent otherwise consents, or (b) contest, protest, or object to any exercise of remedies by, or to any forbearance by, any Secured Party in connection with the Secured Obligations.

4. Confirmation of Waiver of Rights of Subrogation. Each Obligor agrees that no payment or distribution to the Collateral Agent pursuant to the provisions of this Agreement shall entitle such Obligor to exercise, nor shall such Obligor exercise, any rights of subrogation in respect thereof until the termination of this Agreement in accordance with its terms. It is understood by the parties hereto that the foregoing waiver of the exercise of any right of subrogation by each Obligor shall in no event be deemed to be a permanent waiver of such right of subrogation, but shall be effective only until the termination of this Agreement in accordance with its terms.

3

5. Agreements by Obligors. Each Obligor agrees that it will not make any payment of any of the Subordinated Debt under which it is indebted, or take any other action, in contravention of the provisions of this Agreement.

6. Rights of Secured Parties. All rights and interests of the Collateral Agent and the other Secured Parties hereunder, and all agreements and obligations of the Obligors under this Agreement, shall remain in full force and effect (prior to the occurrence of the Subordination Discharge Date (as defined below) and subject to Section 11 hereof) irrespective of:

(a) any extension, modification or renewal of, or indulgence with respect to, or substitution for, the Secured Obligations or any part thereof or any agreement relating thereto at any time (including, without limitation, any change in the time, manner, or place of payment of any of the Secured Obligations);

(b) any failure or omission to perfect or maintain any Lien on, or preserve rights to, any security or Collateral or to enforce any right, power or remedy with respect to the Secured Obligations or any part thereof or any agreement relating thereto, or any Collateral securing the Secured Obligations or any part thereof;

(c) any waiver of any right, power or remedy or of any default with respect to the Secured Obligations or any part thereof or any Facility Agreement or other agreement relating thereto or with respect to any Collateral securing the Secured Obligations or any part thereof (including, without limitation, any manner of application of Collateral, or proceeds thereof, to all or any of the Secured Obligations, or any manner or sale or other disposition of any Collateral for all or any of the Secured Obligations or any other obligations of any other Person under the First Lien Documents or any other assets of any Obligor);

(d) any taking, exchange, release, surrender, compromise, settlement, waiver, subordination or modification, with or without consideration, of any Collateral securing the Secured Obligations or any part thereof, any guaranties with respect to the Secured Obligations or any part thereof, or any other obligations of any Person thereof;

(e) the enforceability or validity of the Secured Obligations or any part thereof or the genuineness, enforceability or validity of any agreement relating thereto or with respect to any Collateral securing the Secured Obligations or any part thereof;

(f) [reserved];

(g) any change of ownership, restructuring, or termination of the corporate structure or existence of any Obligor or the insolvency, bankruptcy or any other change in legal status of any Obligor (subject to Section 11 hereof);

(i) the failure of the Parent or any Obligor to take any other action, or maintain any other approvals, licenses or consents, required in connection with the performance of all obligations pursuant to the Secured Obligations or this Agreement;

(j) the existence of any claim, setoff or other rights which any Obligor may have at any time against any other Obligor in connection herewith or with any unrelated transaction;

(k) the Secured Parties’ election, in any case or proceeding instituted under Debtor Relief Laws, of the application of Section 1111(b)(2) of the Bankruptcy Code;

(l) any borrowing, use of cash collateral, or grant of a security interest by the Parent or any other Obligor, as debtor in possession, under Section 363 of the Bankruptcy Code;

(m) the disallowance of all or any portion of any of the Secured Parties’ claims for repayment of the Secured Obligations under Section 502 or 506 of the Bankruptcy Code;

(n) any refusal of payment by the Collateral Agent or any other Secured Party, in whole or in part, from any Obligor in connection with any of the Secured Obligations, whether or not with notice to, or further assent by, or any reservation of rights against, any Obligor; or

(o) any other fact or circumstance which might otherwise constitute grounds at law or equity for the discharge or release of any Obligor from its obligations hereunder (other than the occurrence of each of the following: (i) the payment in full in cash of all Secured Obligations (other than contingent indemnification obligations not then due), (ii) the termination of the commitments to extend credit or otherwise purchase indebtedness under each of the First Lien Documents, (iii) all letters of credit, secured hedge agreements, and secured cash management arrangements pursuant to the applicable First Lien Documents have been terminated or expired (or have been cash collateralized in an amount satisfactory to the applicable Secured Party and the applicable Authorized Representative, or as to which other arrangements satisfactory to the applicable Secured Party and the applicable Authorized Representative have been made and communicated to the Collateral Agent by the applicable Authorized Representative) (the date upon which each of the foregoing has occurred, the “Subordination Discharge Date”), subject however to Debtor Relief Laws and Section 11 hereof);

in each case, whether or not such Obligor shall have had notice or knowledge of any act or omission referred to in the foregoing clauses (a) through (o) of this Section.

7. Waiver. To the maximum extent permitted by Applicable Law, each Obligor hereby waives (a) promptness, diligence, notice of acceptance and any other notice with respect to any of the Secured Obligations and this Agreement, (b) any requirement that the Collateral Agent or any other Secured Party exhaust any right or take any action against any Obligor or any other Person, and (c) any right to require marshaling of assets.

5

8. No Waiver; Remedies Cumulative. No failure on the part of the Collateral Agent or any other Secured Party to exercise, and no delay in exercising, any rights hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

9. Conflicts. In the event of any conflict between this Agreement and any other provision of any Subordinated Intercompany Debt Agreements or any other agreement, instrument or understanding governing the Subordinated Debt, this Agreement shall control to the extent of such conflict. In the event of any conflict between this Agreement and the Intercreditor Agreement, the Intercreditor Agreement shall control to the extent of such conflict. Without limiting the foregoing, notwithstanding any provision or requirement in any Subordinated Intercompany Debt Agreement to the contrary, the Parties hereto agree that (a) the Secured Obligations shall rank senior in right of payment and enforcement to any such Subordinated Debt to the extent set forth in this Agreement and (b) the terms of the Subordinated Debt may be varied pursuant to the express terms of this Agreement.

10. Joinder. Upon the execution and delivery to the Collateral Agent by any Person of a supplement joinder in substantially the form of Annex I or such other form as may be acceptable to the Collateral Agent (each, a “Joinder”), such Person shall become a “Obligor” hereunder as of the date of such Joinder with the same force and effect as if originally named as a Obligor herein. The execution and delivery of any Joinder shall not require the consent of any other Obligor hereunder, any Credit Party, the Collateral Agent or any other Secured Party. The rights and obligations of each Obligor hereunder shall remain in full force and effect notwithstanding the addition of any new Obligor as a party to this Agreement.

11. Release. To the extent that any Obligor is designated as an Unrestricted Subsidiary pursuant to each of the First Lien Documents, the Parent may elect, by written notice to the Collateral Agent, to have such Obligor discharged from all of its obligations and liabilities under this Agreement, so long as (a) the Parent shall be in compliance with the requirements for designation of Unrestricted Subsidiaries in the First Lien Documents before and after giving effect to such designation and release, and (b) no Default or Event of Default then exists or would be caused thereby. In addition, any Obligor shall be discharged from all of its obligations and liabilities under this Agreement if it ceases to be a Subsidiary of Parent in a transaction permitted under the terms of the First Lien Documents. Upon such election in a written notice to the Collateral Agent in the case of the first sentence in this Section 11, and satisfaction of the other conditions specified in the immediately preceding two sentences, as applicable, the applicable Obligor shall be automatically released from its obligations hereunder without the need for the execution and delivery of any document or instrument by the Collateral Agent or any other Secured Party. Additionally, this Agreement shall automatically terminate upon the Subordination Discharge Date.

12. Continuing Agreement; Termination; Reinstatement. This Agreement is a continuing agreement and shall remain in full force and effect until the termination of this Agreement, be binding upon each Obligor and their respective successors and assigns, and inure to the benefit of and be enforceable by the Collateral Agent and the other Secured Parties and its and their respective permitted successors and assigns. This Agreement shall terminate

6

automatically upon the Subordination Discharge Date. Notwithstanding the foregoing, this Agreement shall continue to be effective or be reinstated, as the case may be, if any payment by or on behalf of an Obligor is made, or the Collateral Agent or any other Secured Party exercises any right of setoff, in respect of the Secured Obligations and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Collateral Agent or any other Secured Party in their discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred regardless of any prior revocation, rescission, termination or reduction.

13. Transfer of Subordinated Debt. Other than an assignment between Restricted Subsidiaries that are Obligors party to this Agreement, no Obligor may assign or transfer its rights and obligations in respect of the Subordinated Debt (other than in a transaction permitted under the First Lien Documents) without the prior written consent of the Collateral Agent, and any such assignment without the Collateral Agent’s prior written consent shall be null and void. Any transferee or assignee of any Subordinated Debt, as a condition to acquiring an interest in such Subordinated Debt shall agree to be bound hereby or by other subordination terms substantially identical to those herein and otherwise acceptable to the Collateral Agent, in a manner satisfactory to the Collateral Agent.

14. No Novation. For the avoidance of doubt, each Subordinated Intercompany Debt Agreement shall continue on and after execution and delivery of this Agreement without any novation, discharge, rescission, extinguishment or substitution of the Obligors’ rights and obligations thereunder pursuant to the terms thereof.

15. Titles and Captions. Titles and captions of Sections, subsections, and clauses in, this Agreement are for convenience only, and neither limit nor amplify the provisions of this Agreement.

16. Severability. Any provision of this Agreement or any other First Lien Document which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remainder of such provision or the remaining provisions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction. In the event that any provision is held to be so prohibited or unenforceable in any jurisdiction, the Collateral Agent (acting on behalf of the Secured Parties) and the Obligors shall negotiate in good faith to amend such provision to preserve the original intent thereof in such jurisdiction.

17. Governing Law and Submission to Jurisdiction. WITH RESPECT TO SECTION 9 AND SECTION 14, THE GOVERNING LAW OF EACH SUBORDINATED INTERCOMPANY DEBT AGREEMENT SHALL CONTINUE TO APPLY TO SUCH SUBORDINATED INTERCOMPANY DEBT AGREEMENT FOR PURPOSES OF CONSTRUING AND INTERPRETING THE EFFECTS OF THIS AGREEMENT ON SUCH SUBORDINATED INTERCOMPANY DEBT AGREEMENT. EXCEPT WITH RESPECT TO SECTION 9 AND SECTION 14, THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
