If and to the extent that any provision of this Sixth Supplemental Indenture limits, qualifies or conflicts with another provision included in this Sixth Supplemental Indenture, by operation of Sections 310 to 317, inclusive, of the Trust Indenture Act (an “incorporated provision”), such incorporated provision shall control.

All other terms used in this Sixth Supplemental Indenture that are defined by the Trust Indenture Act, defined by Trust Indenture Act reference to another statute or defined by SEC rule under the Trust Indenture Act have the meanings so assigned to them.

(g) references to sections of, or rules under, the Securities Act shall be deemed to include substitute, replacement or successor sections or rules adopted by the SEC from time to time;

(h) unless the context otherwise requires, any reference to an “Article,” “Section” or “clause” refers to an Article, Section or clause, as the case may be, of this Sixth Supplemental Indenture; and

-33-

(i) the words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Sixth Supplemental Indenture as a whole and not any particular Article, Section, clause or other subdivision.

In addition, this Sixth Supplemental Indenture restates in their entirety the terms of the Base Indenture as supplemented by this Sixth Supplemental Indenture and does not incorporate the terms of the Base Indenture. The changes, modifications and supplements to the Base Indenture effected by this Sixth Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Notes, except as otherwise provided herein, and shall not apply to any other securities that may be issued under the Base Indenture unless a supplemental indenture with respect to such other securities specifically incorporates such changes, modifications and supplements.

Section 1.05 Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Sixth Supplemental Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Issuer or the Guarantors, as applicable. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Sixth Supplemental Indenture and (subject to Section 7.01) conclusive in favor of the Trustee and the Issuer and the Guarantors, as applicable, if made in the manner provided in this Section 1.05.

Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute proof of the authority of the Person executing the same. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient.

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

Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Holders of each such different part.

(g) Without limiting the generality of the foregoing, a Holder, including DTC that is the Holder of a Global Note, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Sixth Supplemental Indenture to be made, given or taken by Holders, and DTC that is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices.

ARTICLE 2

THE NOTES

In accordance with Section 301 of the Base Indenture, the Issuer hereby creates the Notes as a series of its Securities issued pursuant to this Sixth Supplemental Indenture. In accordance with Section 301 of the Base Indenture, the Notes shall be known and designated as the “4.75% Senior Secured Notes due 2023” of the Issuer.

Section 2.01 Form and Dating; Terms.

(a) General. The Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Note shall be dated the date of its authentication. The Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

(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 attached 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

-35-

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

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Sixth Supplemental Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Sixth Supplemental 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 Sixth Supplemental Indenture, the provisions of this Sixth Supplemental Indenture shall govern and be controlling.

The Notes shall be subject to repurchase by the Issuer pursuant an Asset Sale Offer or Collateral Asset Sale Offer as provided in Section 4.08 hereof or a Change of Control Offer as provided in Section 4.07 hereof. The Notes shall not be redeemable, other than as provided in Article 3.

Additional Notes may be created and issued from time to time by the Issuer without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and shall have the same terms as to status, redemption or otherwise as the Initial Notes. Except as described under Article 9 hereof, the Notes offered by the Issuer and any Additional Notes subsequently issued under this Sixth Supplemental Indenture will be treated as a single class for all purposes under this Sixth Supplemental Indenture, including waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references to “Notes” for all purposes of this Sixth Supplemental Indenture include any Additional Notes that are actually issued. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Sixth Supplemental Indenture.

Section 2.02 Execution and Authentication.

At least one Officer shall execute the Notes on behalf of the Issuer by manual or facsimile signature.

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

A Note shall not be entitled to any benefit under this Sixth Supplemental Indenture or be valid or obligatory for any purpose until authenticated substantially in the form provided for in 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 Sixth Supplemental 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 an Authentication Order authenticate and deliver any Additional Notes. Such Authentication Order shall specify the amount of the Notes to be authenticated.

The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Sixth Supplemental 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 Issuer.

Section 2.03 Registrar and Paying Agent.

The Issuer 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 Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without prior notice to any Holder. The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Sixth Supplemental Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuer or any of its Subsidiaries may act as Paying Agent or Registrar.

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

The Issuer initially appoints Deutsche Bank Trust Company Americas to act as the Paying Agent, Registrar and Transfer Agent for the Notes and the Registrar to act as Custodian with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of 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 will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer 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 Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer 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 Issuer, 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 Issuer shall furnish to the Trustee at least two 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 Issuer shall otherwise comply with Trust Indenture Act Section 312(a).

All Global Notes will be exchanged by the Issuer for Definitive Notes if:

(A) the Issuer delivers to the Trustee notice from the Depositary that the Depositary is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary;

Upon the occurrence of either of the preceding events in (A) or (B) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, pursuant to this Section 2.06 or Sections 2.07 and 2.10 hereof. 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 Sections 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof.

(c) Transfer or Exchange of Beneficial Interests for Definitive Notes. If any holder of a beneficial interest in a Global Note proposes to exchange such beneficial interest for a Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Note, then, upon satisfaction of the conditions set forth in Section 2.06(b) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Note to be reduced accordingly pursuant to Section 2.06(g) hereof, and the Issuer will execute and the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Note in the appropriate principal amount. Any Definitive Note issued in exchange for a beneficial interest pursuant to this Section 2.06(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Notes to the Persons in whose names such Notes are registered.

(d) Transfer and Exchange of Definitive Notes for Beneficial Interests. A Holder of a Definitive Note may exchange such Note for a beneficial interest in a Global Note or transfer such Definitive Notes to a Person who takes delivery thereof in the form of a beneficial interest in a Global Note at any time. Upon receipt of a request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive Note and increase or cause to be increased the aggregate principal amount of one of the Global Notes.

-38-

(e) Transfer and Exchange of Definitive Notes for Definitive Notes. Upon request by a Holder of Definitive Notes and such Holder’s compliance with the provisions of this Section 2.06(e), the Registrar will register the transfer or exchange of Definitive Notes. Prior to such registration of transfer or exchange, the requesting Holder must present or surrender to the Registrar the Definitive Notes duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder must provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section 2.06(e). A Holder of Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of a Definitive Note.

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE SIXTH SUPPLEMENTAL INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE SIXTH SUPPLEMENTAL INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE SIXTH SUPPLEMENTAL INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE SIXTH SUPPLEMENTAL INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

(g) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or cancelled in whole and not in part, each such Global Note shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for

Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(h) General Provisions Relating to Transfers and Exchanges.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request.

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.07, 2.10, 3.06, 4.07 and 9.05 hereof).

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

(v) The Issuer shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date.

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

Every replacement Note is a contractual obligation of the Issuer and shall be entitled to all of the benefits of this Sixth Supplemental 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 cancelled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.07 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 Issuer, 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 Issuer, or by any Affiliate of the Issuer, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee 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 Issuer or any obligor upon the Notes or any Affiliate of the Issuer or of such other obligor.

Section 2.10 Temporary Notes.

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

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 Sixth Supplemental Indenture.

Section 2.11 Cancellation.

The Issuer 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 destroy cancelled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the Issuer. The Issuer 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 Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer 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 Issuer 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 Trustee 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 Trustee shall promptly notify the Issuer of such special record date. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) shall mail or cause to be mailed, first-class postage prepaid, 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 Sixth Supplemental 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.

-42-

Section 2.13 CUSIP and ISIN Numbers.

The Issuer 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 Issuer will as promptly as practicable notify the Trustee of any change in the CUSIP or ISIN numbers.

In the event of partial redemption or purchase by lot, the particular Notes to be redeemed or purchased shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the Redemption Date by the Registrar and Paying Agent from the outstanding Notes not previously called for redemption or purchase.

Except as provided in the preceding sentence, provisions of this Sixth Supplemental Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

The Issuer shall mail or cause to be mailed by first-class mail notices of redemption at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address or otherwise in accordance with the procedures of DTC, except

-43-

that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 13 hereof. Except as set forth in Section 3.07(c) hereof, notices of redemption may not be conditional.

(a) the Redemption Date;

(b) the redemption price (or method of calculating it);

(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 will be issued in the name of the Holder of the Notes upon cancellation of the original Note;

(d) the place and address that payment will be made upon presentation and surrender of the Notes to be redeemed;

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

At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at its expense; provided that the Issuer shall have delivered to the Trustee, at least 2 Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), 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 mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price (except as provided for in Section 3.07(c) hereof). The notice, if mailed 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 by mail 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 thereof called for redemption.

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 Issuer 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.

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

If (a) the notice is mailed in a manner herein provided and (b) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect.

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.

Section 4.08 Asset Sales.

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

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Issuer) of the assets sold or otherwise disposed of; and

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

(A) any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Issuer or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets and for which the Issuer and all of its Restricted Subsidiaries have been validly released by all creditors in writing,

(B) any securities received by the Issuer or such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Sale, and

(C) any Designated Non-cash Consideration received by the Issuer or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this

-53-

clause (C) that is at that time outstanding, not to exceed 5% of Total Assets 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,

shall be deemed to be cash for purposes of this provision and for no other purpose.

(b) Within 450 days after the receipt of any Net Proceeds of any Asset Sale, the Issuer or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale,

(1) to permanently reduce:

(A) Obligations constituting First Lien Obligations (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto) (provided that (x) to the extent that the terms of First Lien Obligations other than Obligations under the Notes require that such First Lien Obligations are repaid with the Net Proceeds of Asset Sales prior to repayment of other Indebtedness, the Issuer and its Restricted Subsidiaries shall be entitled to repay such other First Lien Obligations prior to repaying the Obligations under the Notes and (y) subject to the foregoing clause (x), if the Issuer or any Subsidiary Guarantor shall so reduce First Lien Obligations, the Issuer will equally and ratably reduce Obligations under the Notes through open-market purchases (provided that 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 at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, on the pro rata principal amount of Notes);

(B) Obligations under the Existing Notes which have a final maturity date (as in effect on the Issue Date) on or prior to the Maturity Date of the Notes; provided that, at the time of, and after giving effect to, such repurchase, redemption or defeasance, the aggregate amount of Net Proceeds used to repurchase, redeem or defease Existing Notes pursuant to this subclause (b) following the Issue Date shall not exceed 5% of Total Assets at such time; or

(C) Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Issuer or another Restricted Subsidiary (or any Affiliate thereof);

(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 Issuer or another of its Restricted Subsidiaries, as the case may be, owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) capital expenditures or (c) acquisitions of other assets, in each of (a), (b) and (c), used or useful in a Similar Business; or

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

-54-

provided that, in the case of clauses (2) and (3) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as the Issuer, or such other Restricted Subsidiary enters into such commitment with the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or terminated for any reason before the Net Proceeds are applied in connection therewith, the Issuer or such Restricted Subsidiary enters into another Acceptable Commitment (a “Second Commitment”) within 180 days of such cancellation or termination; provided, further, that if any Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds.

(c) Any Net Proceeds from Asset Sales of Collateral that are not invested or applied as set forth in Section 4.08(b) shall be deemed to constitute “Collateral Excess Proceeds.” When the aggregate amount of Collateral Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes and, if required by the terms of any First Lien Obligations or Obligations secured by a Lien permitted under this Sixth Supplemental Indenture (which Lien is not subordinate to the Lien of the Notes with respect to the Collateral), to the holders of such First Lien Obligations or such other Obligations (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such First Lien Obligations or such other Obligations that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Sixth Supplemental Indenture. The Issuer will commence a Collateral Asset Sale Offer with respect to Collateral Excess Proceeds within ten Business Days after the date that Collateral Excess Proceeds exceed $200.0 million by mailing the notice required pursuant to the terms of this Sixth Supplemental Indenture, with a copy to the Trustee.

Any Net Proceeds from Asset Sales of non-Collateral that are not invested or applied as provided and within the time period set forth in Section 4.08(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Sixth Supplemental Indenture. The Issuer will commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $200.0 million by mailing the notice required pursuant to the terms of this Sixth Supplemental Indenture, with a copy to the Trustee.

To the extent that the aggregate amount of Notes and such other First Lien Obligations or Obligations secured by a Lien permitted by this Sixth Supplemental Indenture (which Lien is not subordinate to the Lien of the Notes with respect to the Collateral) tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, the Issuer may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other covenants contained in this Sixth Supplemental Indenture. To the extent that the aggregate amount of Notes and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in this Sixth Supplemental Indenture. If the aggregate principal amount of Notes or other First Lien Obligations or such other Obligations surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, the Trustee

-55-

shall select the Notes and such other First Lien Obligations or such other Obligations to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such other First Lien Obligations or such other Obligations tendered. If the aggregate principal amount of Notes or the Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered. Upon completion of any such Collateral Asset Sale Offer or Asset Sale Offer, the amount of Collateral Excess Proceeds or Excess Proceeds, as the case may be, shall be reset at zero. Additionally, the Issuer may, at its option, make a Collateral Asset Sale Offer or an Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale; provided that such Collateral Asset Sale Offer or Asset Sale Offer shall be in an aggregate amount of not less than $50.0 million. Upon consummation of such Collateral Asset Sale Offer or Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed Excess Proceeds.

(d) Pending the final application of any Net Proceeds pursuant to this Section 4.08, the holder of such Net Proceeds may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by this Sixth Supplemental Indenture.

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

Section 4.09 Liens.

The Issuer shall not, and shall not permit any Subsidiary Guarantor to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures obligations under any Indebtedness or any related guarantee, on any asset or property of the Issuer or any Subsidiary Guarantor, or any income or profits therefrom, or assign or convey any right to receive income therefrom, other than Liens securing Indebtedness that are junior in priority to the Liens on such property, assets or proceeds securing the Notes and related Subsidiary Guarantees.

The foregoing shall not apply to (a) Liens securing the Notes and the related Subsidiary Guarantees, (b) Liens securing Indebtedness permitted to be incurred under Credit Facilities, including any letter of credit relating thereto, that was permitted by the terms of this Sixth Supplemental Indenture to be incurred pursuant to clause (1) of Section 4.10(b) set forth in the Existing Secured Bond Indentures as in effect on the Issue Date; provided that, with respect to Liens securing Obligations permitted under this subclause (b), the Notes and the related Subsidiary Guarantees are secured by Liens on the assets subject to such Liens (except any European Collateral) to the extent, with the priority and subject to intercreditor arrangements, in each case no less favorable to the Holders of the Notes than those described under Article 10 set forth in the Existing Secured Bond Indentures as in effect on the Issue Date and (c) Liens which are pari passu in priority to the Liens securing the Notes and related Subsidiary Guarantees and are incurred to secure Obligations in respect of any Indebtedness permitted to be incurred pursuant to Section 4.10 set forth in the Existing Secured Bond Indentures as in effect on the Issue Date; provided that, with respect to Liens securing Obligations permitted under this subclause (c), at the time of incurrence and after giving pro forma effect thereto, the ratio of (1) the aggregate amount of Indebtedness secured

-56-

by property, assets or proceeds that secure the Notes and related Subsidiary Guarantees that are subject to a Lien that is pari passu or senior in priority to the Liens securing the Notes and the related Subsidiary Guarantees incurred pursuant to subclause (b) above, this subclause (c) and clause (6) of the definition of “Permitted Liens” (other than Liens securing Indebtedness incurred pursuant to clauses (4) and (18) of Section 4.10(b) set forth in the Existing Secured Bond Indentures as in effect on the Issue Date) to (2) the Issuer’s EBITDA for the most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such event for which such calculation is being made shall occur, in each case with such pro forma adjustments to Indebtedness and EBITDA as are appropriate and consistent with the pro forma adjustment provisions set forth in the definition of Fixed Charge Coverage Ratio would be no greater than 4.25 to 1.0; provided that, with respect to Liens securing Obligations permitted under this subclause (c), the Notes and the related Subsidiary Guarantees are secured by Liens on the assets subject to such Liens (except any European Collateral) to the extent, with the priority and subject to intercreditor arrangements, in each case no less favorable to the Holders of the Notes than those described under Article 10 hereof.

Section 4.10 Discharge and Suspension of Covenants.

(a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under this Sixth Supplemental Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Investment Grade Rating Event”), the Issuer and the Subsidiaries shall not be subject to Section 4.07 hereof (the “Suspended Covenant”).

(b) In the event that the Issuer and the Subsidiaries are not subject to the Suspended Covenant under this Sixth Supplemental Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies (1) withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating and/or (2) the Issuer or any of its Affiliates enters into an agreement to effect a transaction that would result in a Change of Control and one or more of the Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes below an Investment Grade Rating, then the Issuer and the Subsidiaries shall thereafter again be subject to the Suspended Covenant under this Sixth Supplemental Indenture with respect to future events, including, without limitation, a proposed transaction described in clause (2) above.

(c) In the event of any such reinstatement, no action taken or omitted to be taken by the Issuer or any of its Subsidiaries prior to such reinstatement shall give rise to a Default or Event of Default under this Sixth Supplemental Indenture with respect to Notes.

Section 4.11 Covenants Termination and Release of Collateral; Investment Grade Covenants.

(2) Sections 4.11(c), (d) and (e) shall apply to the Issuer and become effective upon the occurrence of such an Investment Grade Rating Event.

(1) Nothing in this Sixth Supplemental Indenture or in the Notes shall in any way restrict or prevent the Issuer, the Parent Guarantor or any Subsidiary from incurring any Indebtedness, provided, however, that neither the Issuer nor any of its Subsidiaries will issue, assume or guarantee any indebtedness or obligation secured by Mortgages upon any Principal Property, unless the Notes shall be secured equally and ratably with (or prior to) such Indebtedness.

(2) The provisions of Section 4.11(c)(1) shall not apply to:

(3) Mortgages securing all or any part of the purchase price of property acquired or cost of construction of property or cost of additions, substantial repairs, alterations or improvements or property, if the Indebtedness and the related Mortgages are incurred within 18 months of the later of the acquisition or completion of construction and full operation or additions, repairs, alterations or improvements;

(3) within 120 days, the Issuer applies the greater of the net proceeds of the sale of the leased property or the fair value of the leased property, net of all Notes delivered under this Sixth Supplemental Indenture, to the voluntary retirement of Funded Debt and/or the acquisition or construction of a Principal Property.

(e) Exempted Transactions.

(1) Notwithstanding the provisions of Sections 4.11(c) and 4.11(d), if the aggregate outstanding principal amount of all Indebtedness of the Issuer and its Subsidiaries that is subject to and not otherwise permitted under these restrictions does not exceed 15% of the Consolidated Net Tangible Assets of the Issuer and its Subsidiaries, then:

(8) to the extent applicable, with respect to any Collateral having a fair market value in excess of $200.0 million, individually or in the aggregate, (a) the security interest under the Security Documents, at any time, ceases to be in full force and effect for any reason other than in accordance with the terms of this Sixth Supplemental Indenture, the Security Documents and the Intercreditor Agreements, (b) any security interest created thereunder or under this Sixth Supplemental Indenture is declared invalid or unenforceable by a court of competent jurisdiction or (c) the Issuer or any Subsidiary Guarantor asserts, in any pleading in any court of competent jurisdiction, that any such security interest is invalid or unenforceable.

Section 6.02 Acceleration.

(a) If any Event of Default (other than an Event of Default specified in clause (5) or (6) of Section 6.01(a) hereof) occurs and is continuing under this Sixth Supplemental Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the then total outstanding Notes may declare the principal amount of all the then outstanding Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal and interest shall be due and payable immediately. The Trustee shall have no obligation to accelerate the Notes if and so long as a committee of its Responsible Officers in good faith determines acceleration is not in the best interest of the Holders of the Notes.

(b) Notwithstanding the foregoing, in the case of an Event of Default arising under clause (5) or (6) of Section 6.01(a) hereof, all outstanding Notes shall be due and payable immediately without further action or notice.

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

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 Sixth Supplemental 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.

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 hereunder, except a past Default in the payment (a) in principal of, premium if any, or interest on, any Note, or in the payment of any sinking fund installment with respect to the Notes, or (b) in respect of a covenant or provision hereof which pursuant to Article 9 hereof cannot be modified or amended, without the consent of Holders of each outstanding Note affected); provided, subject to Section 6.02 hereof, that 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

-63-

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 Sixth Supplemental Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Subject to the terms of the Intercreditor Agreement, the Holders of a majority in 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 of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this Sixth Supplemental 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 in personal liability.

Section 6.06 Limitation on Suits.

Subject to the terms of the Intercreditor Agreement and subject to Section 6.07 hereof, no Holder of a Note may pursue any remedy with respect to this Sixth Supplemental Indenture or the Notes unless:

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

(2) Holders of at least 25% in principal amount of the total outstanding Notes have requested the Trustee to pursue the remedy;

(3) Holders of the Notes have offered the Trustee security or indemnity reasonably satisfactory to it 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; and

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

A Holder of a Note may not use this Sixth Supplemental 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 Sixth Supplemental Indenture, the right of any Holder of a Note to receive payment of principal and premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with a Change of Control 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 Issuer for the whole amount of principal of, premium, if any, and interest remaining unpaid on

-64-

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.

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

Section 6.10 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.

Subject to the terms of the Intercreditor Agreement, the Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (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, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its 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 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

-65-

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.

Subject to the Security Documents, the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

(i) to the Trustee, Paying Agent, Registrar, Transfer 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, Paying Agent, Registrar or Transfer Agent and the costs and expenses of collection;

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 Sixth Supplemental 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% in principal amount of the then outstanding Notes.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign.

Section 7.05 Notice of Defaults.

If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail 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 Issuer shall defend the claim and the Trustee may have separate counsel and the Issuer shall pay the fees and expenses of such counsel. The Issuer need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee’s own willful misconduct, negligence or bad faith.

Such Lien shall survive the satisfaction and discharge of this Sixth Supplemental Indenture.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(a)(5) or (6) 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.

-70-

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 Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Sixth Supplemental Indenture. The successor Trustee shall mail 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.

For this purpose, Legal Defeasance means that the Issuer 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 Sixth Supplemental Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Sixth Supplemental Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.03, 4.04, 4.06, 4.07, 4.08, 4.09, and 4.11 hereof and Section 5.01(a), Sections 5.01(b) and 5.01(c) 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 connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer 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 Sixth Supplemental 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 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(a)(3), 6.01(a)(5), 6.01(a)(6) and 6.01(a)(7) hereof shall not constitute Events of Default.

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 Sixth Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Issuer 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 and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer 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.

If the Trustee or Paying Agent is unable to apply any United States dollars or Government Securities in accordance with Section 8.04 or 8.05 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 Issuer’s obligations under this Sixth Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.04 or 8.05 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.04 or 8.05 hereof, as the case may be; provided that, if the Issuer makes any payment of principal of, premium or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuer and the Trustee may amend or supplement this Sixth Supplemental Indenture, any Guarantee or any Security Document and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes (including 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 or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Sixth Supplemental Indenture, the Guarantees, the Security Documents or the Notes may be waived with the consent of the Holders of a majority in 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 hereof 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 Issuer accompanied by a resolution of its board of directors authorizing the execution of any such amended or supplemental indenture, 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 of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuer in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Sixth Supplemental Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture.

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 or waiver, but it shall be sufficient if such consent approves the substance thereof. The consent of the First Lien Collateral Agent shall not be necessary for any amendment, supplement or waiver to this Sixth Supplemental Indenture, except for any amendment, supplement or waiver to Article 10 or 11 or as to this sentence.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

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) change the stated maturity of the principal of, or installment of interest, if any, on, the Notes, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof;

(2) change the currency in which the principal of (and premium, if any) or interest on such Notes are denominated or payable;

(3) adversely affect the right of repayment or repurchase, if any, at the option of the Holder after such obligation arises, or reduce the amount of, or postpone the date fixed for, any payment under any sinking fund or impair the right to institute suit for the enforcement of any payment on or after the stated maturity thereof (or, in the case of redemption, on or after the Redemption Date);

-77-

(4) reduce the percentage of Holders whose consent is required for modification or amendment of this Sixth Supplemental Indenture or for waiver of compliance with certain provisions of this Sixth Supplemental Indenture or certain defaults;

(5) modify the provisions that require Holder consent to modify or amend this Sixth Supplemental Indenture or that permit Holders to waive compliance with certain provisions of this Sixth Supplemental Indenture or certain defaults;

(6) make any change to or modify the ranking of the Notes or the subordination of the Liens with respect to the Notes that would adversely affect the Holders; or

(7) except as expressly permitted by this Sixth Supplemental Indenture, modify the Guarantees of any Significant Subsidiary in any manner adverse to the Holders of the Notes.

In addition, without the consent of at least 75% in aggregate principal amount of Notes then outstanding, an amendment, supplement or waiver may not:

(1) modify any Security Document or the provisions of this Sixth Supplemental Indenture dealing with the Security Documents or application of trust moneys, or otherwise release any Collateral, in any manner materially adverse to the Holders other than in accordance with this Sixth Supplemental Indenture, the Security Documents and the Intercreditor Agreements; or

(2) modify any Intercreditor Agreement in any manner materially adverse to the Holders other than in accordance with this Sixth Supplemental Indenture, the Security Documents and the Intercreditor Agreements.

Section 9.03 Compliance with Trust Indenture Act.

Every amendment or supplement to this Sixth Supplemental Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies with the Trust Indenture Act as then in effect.

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; provided that any amendment or waiver that requires the consent of each affected Holder shall not become effective with respect to any non-consenting Holder.

The Issuer 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.

-78-

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 Issuer 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 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 or immunities of the Trustee. The Issuer may not sign an amendment, supplement or waiver until the board of directors approves it. In executing any amendment, supplement or waiver, the Trustee 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 14.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Sixth Supplemental Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuer and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, no Opinion of Counsel will be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Sixth Supplemental Indenture.

Section 9.07 Payment for Consent.

Neither the Issuer nor any Affiliate of the Issuer shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Sixth Supplemental Indenture or the Notes unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement.

ARTICLE 12

GUARANTEES

Section 12.01 Subsidiary Guarantee.

Subject to this Article 12, each of the Subsidiary Guarantors hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Sixth Supplemental Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: (a) the principal of, interest, 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 Issuer to the Holders or the Trustee 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 Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

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

Each Subsidiary Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 12.01.

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

-85-

Each Subsidiary 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 Subsidiary Guarantor further agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Subsidiary 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 Subsidiary Guarantors for the purpose of this Subsidiary Guarantee. The Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Subsidiary Guarantees.

Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer 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 Issuer’s 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 Subsidiary 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 Subsidiary 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 Subsidiary Guarantee issued by any Subsidiary Guarantor shall be a senior obligation of such Subsidiary Guarantor and will be secured by a first-priority lien on the Non-Receivables Collateral and by a second-priority lien on the Shared Receivables Collateral. The Subsidiary Guarantees shall rank equally in right of payment with all existing and future Senior Indebtedness of the Subsidiary Guarantor but, to the extent of the value of the Collateral, will be effectively senior to all of the Subsidiary Guarantor’s unsecured Senior Indebtedness and Junior Lien Obligations and, to the extent of the Shared Receivables Collateral, will be effectively subordinated to the Subsidiary Guarantor’s Obligations under the ABL Facility and any future ABL Obligations. The Subsidiary Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each Subsidiary Guarantor. The Notes will be structurally subordinated to Indebtedness and other liabilities of Subsidiaries of the Issuer that do not Guarantee the Notes.

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

As used in this Section 12.01, the term “Trustee” shall also include each of the Paying Agent, Registrar and Transfer Agent, as applicable.

Section 12.02 Limitation on Subsidiary Guarantor Liability.

Each Subsidiary 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 Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary 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 Subsidiary 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 Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under this Article 12, result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Subsidiary Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Sixth Supplemental Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

Section 12.03 Execution and Delivery.

To evidence its Subsidiary Guarantee set forth in Section 12.01 hereof, each Subsidiary Guarantor hereby agrees that this Sixth Supplemental Indenture shall be executed on behalf of such Subsidiary Guarantor by its President, one of its Vice Presidents or one of its Assistant Vice Presidents.

Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 12.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Subsidiary Guarantee on the Notes.

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

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

Section 12.04 Subrogation.

Each Subsidiary Guarantor shall be subrogated to all rights of Holders of Notes against the Issuer in respect of any amounts paid by any Subsidiary Guarantor pursuant to the provisions of Section 12.01 hereof; provided that, if an Event of Default has occurred and is continuing, no Subsidiary 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 Issuer under this Sixth Supplemental Indenture or the Notes shall have been paid in full.

Section 12.05 Benefits Acknowledged.

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

Section 12.06 Release of Guarantees.

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

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

(D) the occurrence of an Investment Grade Rating Event; or

(E) the exercise by the Issuer of its Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the discharge of the Issuer’s obligations under this Sixth Supplemental Indenture, in accordance with the terms of this Sixth Supplemental Indenture; and

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

Section 12.07 Parent Guarantee.

(a) The Parent Guarantor hereby unconditionally guarantees the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all of the monetary obligations of the Issuer under this Sixth Supplemental Indenture and the Notes, whether for principal or interest on the Notes, expenses, indemnification or otherwise (all such obligations of the Parent Guarantor being herein referred to as the “Parent Guaranteed Obligations”).

(b) It is the intention of the Parent Guarantor that the Parent Guarantee 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 the Parent Guarantee. To effectuate the foregoing intention, the amount guaranteed by the Parent Guarantor under the Parent Guarantee shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of the Parent Guarantor that are relevant under such laws, result in the obligations of the Parent Guarantor under the Parent Guarantee not constituting a fraudulent transfer or conveyance.

-88-

(c) The Parent Guarantor guarantees that the Parent Guaranteed Obligations will be paid strictly in accordance with the terms of this Sixth Supplemental Indenture, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of Holders of the Notes with respect thereto. The liability of the Parent Guarantor under the Parent Guarantee shall be absolute and unconditional irrespective of:

(i) any lack of validity, enforceability or genuineness of any provision of this Sixth Supplemental Indenture, the Notes or any other agreement or instrument relating thereto;

(ii) any change in the time, manner or place of payment of, or in any other term of, all or any of the Parent Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from this Sixth Supplemental Indenture;

(iii) any exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any other guarantee, for all or any of the Parent Guaranteed Obligations; or

(iv) any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Issuer or a guarantor.

(d) The Parent Guarantor covenants and agrees that its obligation to make payments of the Parent Guaranteed Obligations hereunder constitutes an unsecured obligation of the Parent Guarantor ranking pari passu with all existing and future senior unsecured indebtedness of the Parent Guarantor that is not subordinated in right of payment to the Parent Guarantee.

(e) The Parent Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to the Parent Guarantee and any requirement that the Trustee, or the Holders of any Notes protect, secure, perfect or insure any security interest or lien or any property subject thereto or exhaust any right or take any action against the Issuer or any other Person or any collateral.

(f) The Parent Guarantor hereby irrevocably waives any claims or other rights that it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of the Parent Guarantor’s obligations under the Parent Guarantee or this Sixth Supplemental Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Trustee, or the Holders of any Notes against the Issuer or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. If any amount shall be paid to the Parent Guarantor in violation of the preceding sentence at any time prior to the cash payment in full of the Parent Guaranteed Obligations and all other amounts payable under the Parent Guarantee, such amount shall be held in trust for the benefit of the Trustee and the Holders of any Notes and shall forthwith be paid to the Trustee, to be credited and applied to the Parent Guaranteed Obligations and all other amounts payable under the Parent Guarantee, whether matured or unmatured, in accordance with the terms of this Sixth Supplemental Indenture and the Parent Guarantee, or be held as collateral for any Parent Guarantor Obligations or other amounts payable under the Parent Guarantee thereafter arising. The Parent Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Sixth Supplemental Indenture and the Parent Guarantee and that the waiver set forth in this Section 10.01 is knowingly made in contemplation of such benefits.

-89-

(g) No failure on the part of the Trustee or any Holder of the Notes to exercise, and no delay in exercising, any right 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.

(h) The Parent Guarantee is a continuing guarantee and shall (a) subject to paragraph 12.07(i), remain in full force and effect until payment in full of the principal amount of all outstanding Notes (whether by payment at maturity, purchase, redemption, defeasance, retirement or other acquisition) and all other applicable Parent Guaranteed Obligations of the Parent Guarantor then due and owing, (b) be binding upon the Parent Guarantor, its successors and assigns, and (c) inure to the benefit of and be enforceable by the Trustee, any Holder of Notes, and by their respective successors, transferees, and assigns.

(i) The Parent Guarantor will automatically and unconditionally be released from all Parent Guarantee Obligations, and the Parent Guarantee shall thereupon terminate and be discharged and of no further force of effect, (i) upon any merger or consolidation of such Parent Guarantor with the Issuer, (ii) upon exercise by the Issuer of its Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the discharge of the Issuer’s obligations under this Sixth Supplemental Indenture, in accordance with the terms of this Sixth Supplemental Indenture, or (iii) upon payment in full of the aggregate principal amount of all Notes then outstanding and all other applicable Parent Guaranteed Obligations of the Parent Guarantor then due and owing.

Upon any such occurrence specified in this paragraph 12.07(i), the Trustee shall execute upon request by the Issuer, any documents reasonably required in order to evidence such release, discharge and termination in respect of the Parent Guarantee. Neither the Issuer nor the Parent Guarantor shall be required to make a notation on the Notes to reflect the Parent Guarantee or any such release, termination or discharge.

(j) The Parent Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer 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 Issuer’s 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 Parent Guarantee, 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.

(k) The Parent Guarantor may amend the Parent Guarantee at any time for any purpose without the consent of the Trustee or any Holder of the Notes; provided, however, that if such amendment adversely affects (a) the rights of the Trustee or (b) any Holder of the Notes, the prior written consent of the Trustee (in the case of (b), acting at the written direction of the Holders of more than 50% in aggregate principal amount of Notes) shall be required.

[Back of Note]

4.75% Senior Secured Notes due 2023

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

1. INTEREST. HCA Inc., a Delaware corporation, promises to pay interest on the principal amount of this Note at 4.75% per annum from October 23, 2012 until maturity. The Issuer will pay interest semi-annually in arrears on May 1 and November 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). 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 May 1, 2013. The Issuer 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 Issuer will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the April 15 and October 15 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Sixth Supplemental Indenture with respect to defaulted interest. 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, premium on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer 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.

3. PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to the Holders. The Issuer or any of its Subsidiaries may act in any such capacity.

4. SIXTH SUPPLEMENTAL INDENTURE. The Issuer issued the Notes under the Base Indenture dated as of August 1, 2011 (the “Base Indenture”) among the HCA Inc., the Guarantors named therein, the Trustee and the Paying Agent, Registrar and Transfer Agent, as supplemented by Supplemental Indenture No. 6, dated as of October 23, 2012 (the “Sixth Supplemental Indenture”), among HCA Inc., the Guarantors named therein, the Trustee and the Paying Agent, Registrar and Transfer Agent. This Note is one of a duly authorized issue of notes of the Issuer designated as its 4.75% Senior Secured Notes due 2023. The Issuer shall be entitled to issue Additional Notes pursuant to Section 2.01 of the Sixth Supplemental Indenture. The terms of the Notes include those stated in the Sixth Supplemental Indenture and those made part of the Sixth Supplemental Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Sixth Supplemental Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Sixth Supplemental Indenture or the Base Indenture, the provisions of the Sixth Supplemental Indenture shall govern and be controlling.

A-5

5. OPTIONAL REDEMPTION.

(a) Except as set forth below, the Issuer will not be entitled to redeem Notes at its option prior to the Maturity Date.

(b) The Notes will be redeemable, at the Issuer’s option, at any time in whole or from time to time in part, at a redemption, or “make-whole,” price equal to the greater of: 100% of the aggregate principal amount of the Notes to be redeemed, and an amount equal to sum of the present value of the remaining scheduled payments of principal of and interest on the Notes to be redeemed (excluding accrued and unpaid interest to the Redemption Date and subject to the right of Holders on the relevant Record Date to receive interest due on the relevant Interest Payment Date) discounted from their scheduled date of payment to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the Treasury Rate plus 50 basis points plus, in each of the above cases, accrued and unpaid interest, if any, to such Redemption Date.

(d) If the Issuer redeems less than all of the outstanding Notes, the Registrar and Paying Agent shall select the Notes to be redeemed in the manner described under Section 3.02 of the Sixth Supplemental Indenture.

(e) Any redemption pursuant to this paragraph 5 shall be made pursuant to the provisions of Sections 3.01 through 3.06 of the Sixth Supplemental Indenture.

6. MANDATORY REDEMPTION. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

7. NOTICE OF REDEMPTION. Subject to Section 3.03 of the Sixth Supplemental Indenture, notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date (except that redemption notices may be mailed more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 11 of the Sixth Supplemental Indenture) to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption.

8. OFFERS TO REPURCHASE.

(a) Upon the occurrence of a Change of Control, the Issuer shall make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”). The Change of Control Offer shall be made in accordance with Section 4.07 of the Sixth Supplemental Indenture.

(b) If the Issuer or any of its Restricted Subsidiaries consummates an Asset Sale of Collateral, within 10 Business Days of each date that the aggregate amount of Collateral Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes and, if required by the terms of any First Lien Obligations or Obligations secured by a Lien permitted under the Sixth Supplemental

A-6

Indenture (which Lien is not subordinate to the Lien of the Notes with respect to the Collateral), to the holders of such First Lien Obligations or such other Obligations (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such First Lien Obligations or such other Obligations that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Sixth Supplemental Indenture. To the extent that the aggregate amount of Notes and such other First Lien Obligations or Obligations secured by a Lien permitted by the Sixth Supplemental Indenture (which Lien is not subordinate to the Lien of the Notes with respect to the Collateral) tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, the Issuer may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other covenants contained in the Sixth Supplemental Indenture. If the aggregate principal amount of Notes or other First Lien Obligations or such other Obligations surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, the Registrar and Paying Agent shall select the Notes and such other First Lien Obligations or such other Obligations to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such other First Lien Obligations or such other Obligations tendered. Upon completion of any such Collateral Asset Sale Offer, the amount of Collateral Excess Proceeds shall be reset at zero.

(c) If the Issuer or any of its Restricted Subsidiaries consummates an Asset Sale of non-Collateral, within 10 Business Days of each date that the aggregate amount of Excess Proceeds exceeds $200.0 million, the Issuer shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Sixth Supplemental Indenture. To the extent that the aggregate amount of Notes and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Sixth Supplemental Indenture. If the aggregate principal amount of Notes or Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

(d) The Issuer may, at its option, make a Collateral Asset Sale Offer or Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale; provided that such Collateral Asset Sale Offer or Asset Sale Offer shall be in an aggregate amount of not less than $50.0 million. Upon consummation of such Collateral Asset Sale Offer or Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed Excess Proceeds.

9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Sixth Supplemental Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Sixth Supplemental Indenture. The Issuer need not exchange or register the transfer of any Notes or portion of Notes selected for redemption, except for the unredeemed portion of any Notes being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

A-7

10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

11. AMENDMENT, SUPPLEMENT AND WAIVER. The Sixth Supplemental Indenture, the Guarantees or the Notes may be amended or supplemented as provided in the Sixth Supplemental Indenture.

12. DEFAULTS AND REMEDIES. The Events of Default relating to the Notes are defined in Section 6.01 of the Sixth Supplemental Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes 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. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce Sixth Supplemental Indenture, the Guarantees or the Notes except as provided in the Sixth Supplemental Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its consequences under the Sixth Supplemental Indenture except a continuing Default in payment of the principal of, premium, if any, or interest on, any of the Notes held by a non-consenting Holder. The Issuer is required to deliver to the Trustee annually a statement regarding compliance with the Sixth Supplemental Indenture, and the Issuer is required within five (5) Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and what action the Issuer proposes to take with respect thereto.

13. AUTHENTICATION. This Note shall not be entitled to any benefit under the Sixth Supplemental Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of the Trustee.

14. [RESERVED].

15. GOVERNING LAW. THE SIXTH SUPPLEMENTAL INDENTURE, THE NOTES, THE PARENT GUARANTEE AND ANY GUARANTEE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

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

[FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS]

Supplemental Indenture (this “Supplemental Indenture”), dated as of , among (the “Guaranteeing Subsidiary”), a subsidiary of HCA Inc., a Delaware Corporation (the “Issuer”), Law Debenture Trust Company of New York, as trustee (the “Trustee”) and Deutsche Bank Trust Company Americas, as Paying Agent, Registrar and Transfer Agent

W I T N E S S E T H

WHEREAS, each of HCA Inc. and the Guarantors (as defined in the Sixth Supplemental Indenture referred to below) have heretofore executed and delivered to the Trustee an indenture (the “Sixth Supplemental Indenture”), dated as of October 23, 2012, providing for the issuance of an unlimited aggregate principal amount of 4.75% Senior Secured Notes due 2023 (the “Notes”);

WHEREAS, the Sixth Supplemental Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Sixth Supplemental Indenture on the terms and conditions set forth herein and under the Sixth Supplemental Indenture (the “Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the Sixth Supplemental Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

(1) Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Sixth Supplemental Indenture.

(2) Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows:

(a) Along with all Guarantors named in the Sixth Supplemental Indenture, to jointly and severally unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, the Paying Agent, the Registrar and the Transfer Agent and their successors and assigns, irrespective of the validity and enforceability of the Sixth Supplemental Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(i) the principal of and interest, premium on the Notes will 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 Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed

B-1

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 and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection.

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

(c) The following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever.

(d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Sixth Supplemental Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts all obligations of a Guarantor under the Sixth Supplemental Indenture.

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

(f) The Guaranteeing Subsidiary 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.

(g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Sixth Supplemental Indenture 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 of the Sixth Supplemental Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guaranteeing Subsidiary for the purpose of this Guarantee.

(h) The Guaranteeing Subsidiary 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 this Guarantee.

(i) Pursuant to Section 12.02 of the Sixth Supplemental Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy Law or fraudulent conveyance 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 Article 12 of the Sixth Supplemental Indenture, this new Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under this Guarantee will not constitute a fraudulent transfer or conveyance.

B-2

(j) This Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer 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 Issuer’s 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 and Guarantee, 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 Note 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.

(k) In case any provision of this 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.

(l) This Guarantee shall be a general senior obligation of such Guaranteeing Subsidiary, ranking equally in right of payment with all existing and future Senior Indebtedness of the Guaranteeing Subsidiary but, to the extent of the value of the Collateral, will be effectively senior to all of the Guaranteeing Subsidiary’s unsecured Senior Indebtedness and Junior Lien Obligations and, to the extent of the Shared Receivables Collateral, will be effectively subordinated to the Guaranteeing Subsidiary’s Obligations under the ABL Facility and any future ABL Obligations. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each Guarantor. The Notes will be structurally subordinated to Indebtedness and other liabilities of Subsidiaries of the Issuer that do not Guarantee the Notes, if any.

(m) Each payment to be made by the Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

(3) Execution and Delivery. The Guaranteeing Subsidiary agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

(4) Merger, Consolidation or Sale of All or Substantially All Assets.

(a) Except as otherwise provided in Section 5.01(c) of the Sixth Supplemental Indenture, the Guaranteeing Subsidiary may not consolidate or merge with or into or wind up into (whether or not the Issuer or Guaranteeing Subsidiary is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless:

(i) such Guarantor is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor, as the case may be, or the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (such Guarantor or such Person, as the case may be, being herein called the “Successor Person”);

B-3

(ii) the Successor Person, if other than such Guarantor, expressly assumes all the obligations of such Guarantor under the Sixth Supplemental Indenture and such Guarantor’s related Guarantee pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee;

(iii) immediately after such transaction, no Default exists; and

(iv) the Issuer shall have delivered to the Trustee an Officer’s Certificate, each stating that such consolidation, merger or transfer and such supplemental indentures, if any, comply with the Sixth Supplemental Indenture; or

(v) the transaction is made in compliance with Section 4.08 of the Sixth Supplemental Indenture.

(b) Subject to certain limitations described in the Sixth Supplemental Indenture, the Successor Person will succeed to, and be substituted for, such Guarantor under the Sixth Supplemental Indenture and such Guarantor’s Guarantee. Notwithstanding the foregoing, any Guarantor may (i) merge into or transfer all or part of its properties and assets to another Guarantor or the Issuer, (ii) merge with an Affiliate of the Issuer solely for the purpose of reincorporating the Guarantor in the United States, any state thereof, the District of Columbia or any territory thereof or (iii) convert into a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor.

(5) Releases. The Guarantee of the Guaranteeing Subsidiary shall be automatically and unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Issuer or the Trustee is required for the release of the Guaranteeing Subsidiary’s Guarantee, upon:

(1) (A) any sale, exchange or transfer (by merger 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 all or substantially all the assets of such Guarantor which sale, exchange or transfer is made in compliance with the applicable provisions of the Sixth Supplemental Indenture;

(B) the release or discharge of the guarantee by such Guarantor of the Senior Credit Facilities or such other guarantee that resulted in the creation of such Guarantee, except a discharge or release by or as a result of payment under such guarantee;

(C) the designation of such Guarantor, if a Restricted Subsidiary, as an Unrestricted Subsidiary in compliance with the definition of “Unrestricted Subsidiary” hereunder;

(D) the occurrence of an Investment Grade Rating Event; or

(E) the exercise by Issuer of its Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the Issuer’s obligations under the Sixth Supplemental Indenture being discharged in accordance with the terms of the Sixth Supplemental Indenture; and

B-4

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

(6) No Recourse Against Others. No director, officer, employee, incorporator or stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Issuer or the Guarantors (including the Guaranteeing Subsidiary) under the Notes, any Guarantees, the Sixth Supplemental Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

(7) Governing Law. THIS SUPPLEMENTAL INDENTURE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(8) Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

(9) Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

(10) The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary.

(11) Subrogation. The Guaranteeing Subsidiary shall be subrogated to all rights of Holders of Notes against the Issuer in respect of any amounts paid by the Guaranteeing Subsidiary pursuant to the provisions of Section 2 hereof and Section 12.01 of the Sixth Supplemental Indenture; provided that, if an Event of Default has occurred and is continuing, the Guaranteeing Subsidiary shall not 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 Issuer under the Sixth Supplemental Indenture or the Notes shall have been paid in full.

(12) Benefits Acknowledged. The Guaranteeing Subsidiary’s Guarantee is subject to the terms and conditions set forth in the Sixth Supplemental Indenture. The Guaranteeing Subsidiary acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Sixth Supplemental Indenture and this Supplemental Indenture and that the guarantee and waivers made by it pursuant to this Guarantee are knowingly made in contemplation of such benefits.

(13) Successors. All agreements of the Guaranteeing Subsidiary in this Supplemental Indenture shall bind its Successors, except as otherwise provided in Section 2(k) hereof or elsewhere in this Supplemental Indenture. All agreements of the Trustee in this Supplemental Indenture shall bind its successors.
