“Existing Notes Indentures” means each of the indentures or other documents containing the terms of the Existing Notes.

“Expenses Relating to a Unit Outage” means any expenses or other charges as a result of any outage or shut-down of any Unit, including any expenses or charges relating to (a) restarting any such Unit so that it may be placed back in service after such outage or shut-down, (b) purchases of power, natural gas or heat rate to meet commitments to sell, or offset a short position in, power, natural gas or heat rate that would otherwise have been met or offset from production generated by such Unit during the period of such outage or shut-down, net of the expenses not in fact incurred (including fuel and other operating expenses) that would have been incurred absent such outage or shut down and (c) starting up, operating, maintaining and shutting down any other Unit that would not otherwise have been operating absent such outage or shut-down, including the fuel and other operating expenses to the extent in excess of the expenses not in fact incurred (including fuel and other operating costs) that would have been incurred absent such outage or shut down, incurred to start-up, operate, maintain and shut-down such Unit and that are required during the period of time that the shut-down or outaged Unit is out of service in order to meet the commitments of such shut-down or outaged Unit to sell, or offset a short position in, power, natural gas or heat rate.

“Fixed Charge Coverage Ratio” means, with respect to any Person for any period, the ratio of EBITDA of such Person for such period to the Fixed Charges of such Person for such period. In the event that the Issuer or any Restricted Subsidiary incurs, assumes, guarantees, redeems, retires or extinguishes any Indebtedness (other than Indebtedness incurred under any revolving credit facility unless such Indebtedness has been permanently repaid and has not been replaced) or issues or redeems Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but prior to or simultaneously with the event for which the calculation of the Fixed Charge Coverage Ratio is made (the “Fixed Charge Coverage Ratio Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption, retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (as determined in accordance with GAAP) that have been made by the Issuer or any of its Restricted Subsidiaries during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Fixed Charge Coverage Ratio Calculation Date shall be calculated on a pro forma basis assuming that all such

Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (and the change in any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If, since the beginning of such period, any Person that subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any of its Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, consolidation or disposed operation that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition, merger, consolidation or disposed operation had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of the Issuer. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Fixed Charge Coverage Ratio Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period except as set forth in the first paragraph of this definition. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate or other rate shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

“Fixed Charges” means, with respect to any Person for any period, the sum of:

(1) Consolidated Interest Expense of such Person for such period;

Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Senior Note, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 1.05.

ARTICLE 2

THE SENIOR NOTES

Section 2.01

Form and Dating; Terms.

(a) General. The Senior Notes and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A-1 (in the case of Senior Cash Pay Notes) or Exhibit A-2 (in the case of Senior Toggle Notes) hereto. The Senior Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Senior Note shall be dated the date of its authentication. The Senior Notes shall be in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, subject to the issuance of certificated PIK Notes as set forth in Exhibit A-2.

(b) Global Notes. Senior Notes issued in global form shall be substantially in the form of Exhibit A-1 (in the case of Senior Cash Pay Notes) or Exhibit A-2 (in the case of the Senior Toggle Notes) hereto (including, in each case, the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Senior Notes issued in definitive form shall be substantially in the form of Exhibit A-1 (in the case of Senior Cash Pay Notes) or Exhibit A-2 (in the case of the Senior Toggle Notes) attached hereto (but without, in each case, 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 Senior 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 Senior Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Senior Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Senior Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

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

(i) a written certificate from the Depositary (if available), together with copies of certificates from Euroclear and Clearstream (if available) certifying that they have received certification of non-United States beneficial ownership of 100% of the aggregate principal

amount of the Regulation S Temporary Global Note (except to the extent of any beneficial owners thereof who acquired an interest therein during the Restricted Period pursuant to another exemption from registration under the Securities Act and who shall take delivery of a beneficial ownership interest in a 144A Global Note bearing a Private Placement Legend, all as contemplated by Section 2.06(b) hereof); and

(ii) an Officer’s Certificate from the Issuer.

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

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

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

The Senior Notes shall be subject to repurchase by the Issuer pursuant to an Asset Sale Offer as provided in Section 4.10 hereof or a Change of Control Offer as provided in Section 4.14 hereof. The Senior Notes shall not be redeemable other than as provided in Article 3 hereof.

Additional Senior Notes ranking pari passu with the Initial Senior 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 Senior Notes and shall have the same terms as to status, redemption or otherwise as the Initial Senior Notes; provided that the Issuer’s ability to issue Additional Senior Notes shall be subject, among other things, to the Issuer’s compliance with Section 4.09 hereof; provided further that in connection with the payment of PIK Interest, the Issuer may, without the consent of the Holders (and without regard to any restrictions or limitations set forth in Section 4.09 hereof), increase the outstanding principal amount of the Senior Toggle Notes or issue PIK Notes. The Senior Cash Pay Notes and the Senior Toggle Notes are each a separate series of Senior Notes but will be treated as a single class of securities under this Indenture, except as otherwise stated herein. As a result, Holders of each series of Senior Notes will not have separate rights to, among other things, give notice of Defaults or to direct the Trustee to exercise remedies during an Event of Default or otherwise. Except as described under Article 9 hereof, the Senior Notes offered by the Issuer, the PIK Notes and any Additional Senior Notes subsequently issued under this Indenture will be treated as a single class for all purposes under this Indenture, including, among other things, waivers, amendments, redemptions and offers to purchase. Unless the context requires otherwise, references to “Senior Notes” for all purposes under this Indenture include any PIK Notes and Additional Notes that are actually issued, and references to “principal amount” of the Senior Notes includes any increases in the principal amount of the outstanding Senior Notes as a result of a PIK Payment. Any Additional Senior Notes shall be issued with the benefit of an indenture supplemental to this Indenture.

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

Section 2.02

Execution and Authentication.

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

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

A Senior Note shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated substantially in the form of Exhibit A-1 (in the case of Senior Cash Pay Notes) or Exhibit A-2 (in the case of Senior Toggle Notes) attached hereto, as the case may be, by the manual signature of the Trustee. The signature shall be conclusive evidence that the Senior Note has been duly authenticated and delivered under this Indenture.

On the Issue Date, the Trustee shall, upon receipt of a written order of the Issuer signed by an Officer (an “Issuer Authentication Order”), authenticate and deliver (i) the Initial Senior Cash Pay Notes and (ii) the Initial Senior Toggle Notes. In addition, at any time, and from time to time, the Trustee shall, upon receipt of an Issuer Authentication Order, authenticate and deliver any Additional Senior Notes, Exchange Notes or PIK Notes (or increases in the principal amount of any Senior Toggle Notes) as a result of a PIK Payment, for an aggregate principal amount specified in such Issuer Authentication Order for such Additional Senior Notes, Exchange Notes or PIK Notes (or increases in the principal amount of such Senior Toggle Notes). Such Issuer Authentication Order shall specify the amount of the Senior Notes to be authenticated and, in the case of any issuance of Additional Senior Notes, shall certify that such issuance is in compliance with Section 4.09 hereof.

On any Interest Payment Date on which the Issuer pays PIK Interest with respect to a Global Note, the Trustee shall increase the principal amount of such Global Note by an amount equal to the interest payable, rounded up to the nearest $1,000, for the relevant interest period on the principal amount of such Global Note as of the relevant Record Date, for such Interest Payment Date, to the credit of the Holders on such Record Date, pro rata in accordance with their interests, and an adjustment shall be made on the books and records of the Trustee (if it is then the Custodian for such Global Note) with respect to such Global Note, by the Trustee or the Custodian, to reflect such increase. On any Interest Payment Date on which the Issuer pays PIK Interest by issuing definitive PIK Notes, the principal amount of any such PIK Notes issued to any Holder, for the relevant interest period as of the relevant Record Date for such Interest Payment Date, shall be rounded up to the nearest $1.00.

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

Section 2.03

Registrar and Paying Agent.

The Issuer shall maintain an office or agency where Senior Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Senior Notes may be

presented for payment (“Paying Agent”). The Registrar shall keep a register of the Senior 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 Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such Registrar or Paying Agent. The Issuer or any of its Subsidiaries may act as Registrar or Paying Agent.

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

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent for the Senior Notes and 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, Additional Interest if any, or cash interest on the Senior 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 Senior 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 Senior Notes and the Issuer shall otherwise comply with Trust Indenture Act Section 312(a).

Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Senior Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events in (i) or (ii) above and pursuant to Section 2.06(c) hereof. A Global Note may not be exchanged for another Senior Note other than as provided in this Section 2.06(a); provided, however, that beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.

Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i).

(iii) Transfer of Beneficial Interests to Another Restricted Global Note.

(i) 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 a Issuer 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, 3.09, 4.10, 4.14 and 9.05 hereof).

(iii) Neither the Registrar nor the Issuer shall be required to register the transfer of or exchange any Senior Note selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part.

(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 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 Senior Notes during a period beginning at the opening of business 15 days before the day of any selection of Senior 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 Senior Note so selected for redemption in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part; or (C) to register the transfer of or to exchange a Senior Note between a Record Date and the next succeeding Interest Payment Date.

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

(vii) Upon surrender for registration of transfer of any Senior Note at the office or agency of the Issuer designated pursuant to Section 4.02 hereof, the Issuer shall execute, and the Trustee shall authenticate and mail, in the name of the designated transferee or transferees, one or more replacement Senior Notes of any authorized denomination or denominations of a like aggregate principal amount.

Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and mail, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02 hereof.

(ix) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

Section 2.07

Replacement Senior Notes.

If any mutilated Senior Note is surrendered to the Trustee, the Registrar or the Issuer and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Senior Note, the Issuer shall issue and the Trustee, upon receipt of a Issuer Authentication Order, shall authenticate a replacement Senior Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Senior Note is replaced. The Issuer and the Trustee may charge for their expenses in replacing a Senior Note.

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

Section 2.08

Outstanding Senior Notes.

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

If a Senior 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 Senior Note is held by a protected purchaser.

If the principal amount of any Senior 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 Senior Notes payable on that date, then on and after that date such Senior 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 Senior Notes have concurred in any direction, waiver or consent, any Senior Notes owned by the Issuer or 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 Senior Notes that a Responsible Officer of the Trustee knows are so owned, shall be so disregarded. Senior 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 Senior Notes and that the pledgee is not the Issuer or any obligor upon the Senior Notes or any Affiliate of the Issuer or of such other obligor.

Section 2.10

Temporary Senior Notes.

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

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

Section 2.11

Cancellation.

The Issuer at any time may deliver Senior Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Senior 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 Senior Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Senior Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Senior Notes shall be delivered to the Issuer upon the Issuer’s written request. The Issuer may not issue new Senior Notes to replace Senior Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12

Defaulted Cash Interest.

If the Issuer defaults in a payment of cash interest on the Senior Notes, it shall pay the defaulted cash interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted cash interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Senior Notes and in Section 4.01 hereof. The Issuer shall notify the Trustee in writing of the amount of defaulted cash interest proposed to be paid on each Senior 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 cash 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 cash 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 cash 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 Senior Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Senior Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Senior Note.

Section 2.13

▇▇▇▇▇ and ISIN Numbers.

The Issuer in issuing the Senior 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 Senior Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Senior 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.

ARTICLE 3

In the event of partial redemption or purchase by lot, the particular Senior 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 Trustee from the outstanding Senior Notes not previously called for redemption or purchase.

The Trustee shall promptly notify the Issuer in writing of the Senior Notes selected for redemption or purchase and, in the case of any Senior Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Senior Notes and portions of Senior Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; no Senior Notes of $2,000 or less can be redeemed in part, except that if all of the Senior Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Senior Notes held by such Holder, even if not $2,000 or a multiple of $1,000 in excess thereof, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Senior Notes called for redemption or purchase also apply to portions of Senior Notes called for redemption or purchase.

Section 3.03

Notice of Redemption.

Subject to Section 3.09 hereof, notices of redemption shall be mailed by first-class mail, postage prepaid, at least 30 days but not more than 60 days before the Redemption Date to each Holder of Senior Notes to be redeemed at such Holder’s registered address or otherwise in accordance with the procedures of DTC, except that notices of redemption 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 hereof. Except as set forth in Section 3.04, Section 3.07(c) and Section 3.07(d) hereof, notices of redemption may not be conditional.

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

(a) the Redemption Date;

(b) the redemption price;

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

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

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

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

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

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

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, Senior 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) and 3.07(d) 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 Senior Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Senior Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to accrue on Senior Notes or portions of Senior Notes called for redemption.

Section 3.05

Deposit of Redemption or Purchase Price.

Prior to 10:00 a.m. (New York City time) on the redemption or purchase date, the Issuer shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest (including Additional Interest, if any) on all Senior Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest (including Additional Interest, if any) on, all Senior Notes to be redeemed or purchased.

(2) at the time of incurrence, the Issuer will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.09(a) and (b) hereof;

provided that all Indebtedness outstanding under the TCEH Senior Secured Facilities on the Closing Date will be treated as incurred on the Closing Date under Section 4.09(b)(1) hereof.

(d) Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness, Disqualified Stock or Preferred Stock shall not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this Section 4.09.

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced.

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

(f) Notwithstanding anything to the contrary, the Issuer shall not, and shall not permit any Guarantor to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of the Issuer or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in right of payment to the Senior Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Issuer or such Guarantor, as the case may be.

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

Section 4.10

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 Senior Notes or that are owed to the Issuer or an Affiliate of the Issuer, 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 applicable 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 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 under Senior Indebtedness which is Secured Indebtedness permitted by this Indenture, and to correspondingly reduce commitments with respect thereto;

(B) Obligations under other Senior Indebtedness (and to correspondingly reduce commitments with respect thereto); provided that the Issuer shall equally and ratably reduce Obligations under the Senior Notes as provided under Section 3.07 hereof, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or otherwise by making an offer (in accordance with the procedures set forth below under this Section 4.10) to all Holders to purchase their Senior Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any;

(C) Obligations under the Existing Notes which have a final maturity date (as in effect on the Closing Date) on or prior to October 15, 2017, 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 (C) following the Closing Date shall not exceed 3.5% of Total Assets at such time; or

(d) 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);

provided that, if an offer to purchase any Indebtedness of TCEH or any of its Restricted Subsidiaries is made in accordance with the terms of such Indebtedness, the obligation to permanently reduce Indebtedness of a Restricted Subsidiary will be deemed to be satisfied to the extent of the amount of the offer, whether or not accepted by the holders thereof, and no Net Proceeds in the amount of such offer will be deemed to exist following such offer;

(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;

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 reinvest within the later of 450 days from the date of receipt of Net Proceeds and 180 days of receipt of such 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 the later of (a) 180 days of such cancellation or termination or (b) the initial 450-day period; 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.

Notwithstanding Section 4.10(b) hereof, in the event that regulatory approval is necessary for an asset or investment, or replacement, repair or restoration on any asset or investment, then the Issuer or any Restricted Subsidiary shall have an additional 365 days to apply the Net Proceeds from such Asset Sale in accordance with Section 4.10(b) hereof.

Any Net Proceeds from Asset Sales that are not invested or applied as provided and within the time period set forth in the first sentence of Section 4.10(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 Senior 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 Senior 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 and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer will commence 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 Indenture, with a copy to the Trustee.

To the extent that the aggregate amount of Senior 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 Indenture. If the aggregate principal amount of Senior Notes or the Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the

Senior Notes or such Senior Indebtedness tendered. Additionally, the Issuer may, at its option, make an Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale; provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of such Asset Sale Offer, any Net Proceeds not required to be used to purchase Senior Notes shall not be deemed Excess Proceeds.

(c) Pending the final application of any Net Proceeds pursuant to this Section 4.10, the holder of such Net Proceeds may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by this Indenture.

(d) 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 Senior Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Indenture by virtue thereof.

Section 4.11

Transactions with Affiliates.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Issuer (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $25.0 million, unless:

(1) such Affiliate Transaction is on terms that are not materially less favorable to the Issuer or its relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis; and

(2) the Issuer delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $50.0 million, a resolution adopted by the majority of the board of directors of the Issuer approving such Affiliate Transaction and set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of this Section 4.11(a).

(b) The provisions of Section 4.11(a) hereof shall not apply to the following:

(1) transactions between or among the Issuer or any of its Restricted Subsidiaries or between or among the Issuer, any of its Restricted Subsidiaries and the Oncor Subsidiaries in the ordinary course of business;

(2) Restricted Payments permitted by Section 4.07 hereof and the definition of “Permitted Investments”;

case as in effect on the Closing Date, or any amendment thereto (so long as any such amendment is not disadvantageous in the good faith judgment of the board of directors of the Issuer to the Holders when taken as a whole as compared to the Sponsor Management Agreement in effect on the Closing Date);

(4) the payment of reasonable and customary fees paid to, and indemnities provided for the benefit of, officers, directors, employees or consultants of the Issuer, any of its direct or indirect parent companies or any of its Restricted Subsidiaries;

(6) any agreement as in effect as of the Closing Date, or any amendment thereto (so long as any such amendment is not disadvantageous to the Holders when taken as a whole as compared to the applicable agreement as in effect on the Closing Date);

(7) the existence of, or the performance by the Issuer or any of its Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Closing Date and any similar agreements which it may enter into thereafter; provided, however, that the existence of, or the performance by the Issuer or any of its Restricted Subsidiaries of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Closing Date shall only be permitted by this clause (7) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous to the Holders when taken as a whole;

(8) the Transactions (including payments made after the Closing Date in respect of the Issuer’s and its Subsidiaries’ long-term incentive plan or in respect of tax gross-ups and other deferred compensation) and the payment of all fees and expenses related to the Transactions, in each case as disclosed in the Offering Memorandum;

(9) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to the Issuer and its Restricted Subsidiaries, in the reasonable determination of the board of directors of the Issuer or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

(10) the issuance of Equity Interests (other than Disqualified Stock) of the Issuer to any Permitted Holder or to any director, officer, employee or consultant;

(11) sales of accounts receivable, or participations therein, in connection with any Receivables Facility for the benefit of the Issuer or any of its Restricted Subsidiaries;

(15) payments by the Issuer (and any direct or indirect parent thereof) and its Subsidiaries pursuant to tax sharing agreements among the Issuer (and any such parent) and its Subsidiaries on customary terms to the extent attributable to the ownership or operation of the Issuer and its Subsidiaries; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that the Issuer, its Restricted Subsidiaries and its Unrestricted Subsidiaries (to the extent of amounts received from Unrestricted Subsidiaries) would be required to pay in respect of foreign, federal, state and local taxes for such fiscal year were the Issuer and its Subsidiaries (to the extent described above) to pay such taxes separately from any such parent entity.

Section 4.12

Liens.

The Issuer shall not, and shall not permit any 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 Guarantor, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless:

(1) in the case of Liens securing Subordinated Indebtedness, the Senior Notes and related Guarantees are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens; or

(2) in all other cases, the Senior Notes or the Guarantees are equally and ratably secured or are secured by a Lien on such property, assets or proceeds that is senior in priority to such Liens;

except that the foregoing shall not apply to (a) Liens securing the Senior Notes and the related 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 Indenture to be incurred pursuant to clause (1) of Section 4.09(b) and (c) Liens incurred to secure Obligations in respect of any Indebtedness permitted to be incurred pursuant to Section 4.09 hereof; provided that, with respect to Liens securing Obligations permitted under this clause (c), at the time of incurrence and after giving pro forma effect thereto, the Consolidated Secured Debt Ratio 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, would be no greater than 5.0 to 1.0. Any Lien which is granted to secure the Senior Notes under this Section 4.12 shall be discharged at the same time as the discharge of the Lien (other than through the exercise of remedies with respect thereto) that gave rise to the obligations to secure the Senior Notes.

Section 4.13

Corporate Existence.

Subject to Article 5 hereof, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuer or any such Restricted Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Issuer and its Restricted Subsidiaries; provided that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Issuer in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Restricted Subsidiaries, taken as a whole.

Section 4.14

Offer to Repurchase upon Change of Control.

(a) If a Change of Control occurs, unless the Issuer has previously or concurrently mailed a redemption notice with respect to all the outstanding Senior Notes as described under Section 3.07 hereof and will redeem all of the outstanding Senior Notes pursuant thereto, the Issuer shall make an offer to purchase all of the Senior Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase, subject to the right of Holders of the Senior Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuer shall send notice of such Change of Control Offer by first-class mail, with a copy to the Trustee, to each Holder of Senior Notes to the address of such Holder appearing in the security register with a copy to the Trustee or otherwise in accordance with the procedures of DTC, with the following information:

(1) that a Change of Control Offer is being made pursuant to this Section 4.14 and that all Senior Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment by the Issuer;

(2) the purchase price and the purchase date, which will be no earlier than 30 days nor later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

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

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

(5) that Holders electing to have any Senior Notes purchased pursuant to a Change of Control Offer will be required to surrender such Senior Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Senior 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;

(6) that Holders shall be entitled to withdraw their tendered Senior Notes and their election to require the Issuer to purchase such Senior Notes; provided that the Paying Agent receives, not later than the close of business on the expiration date of the Change of Control Offer, a telegram, facsimile transmission or letter setting forth the name of the Holder of the

Senior Notes, the principal amount of Senior Notes tendered for purchase, and a statement that such ▇▇▇▇▇▇ is withdrawing its tendered Senior Notes and its election to have such Senior Notes purchased;

(7) that the Holders whose Senior Notes are being repurchased only in part will be issued new Senior Notes and such new Senior Notes will be equal in principal amount to the unpurchased portion of the Senior Notes surrendered. The unpurchased portion of the Senior Notes must be equal to $2,000 or an integral multiple of $1,000 in excess thereof; and

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

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. If (a) 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 Senior Notes as to all other Holders that properly received such notice without defect. The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Senior Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.14, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by virtue thereof.

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

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

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

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

(c) The Paying Agent shall promptly mail to each Holder the Change of Control Payment for such Senior Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Senior Note equal in principal amount to any unpurchased portion of the Senior Notes surrendered, if any; provided that each such new Senior Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

(d) The Issuer shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 applicable to a Change of Control Offer made by the Issuer and purchases all Senior Notes validly tendered and not withdrawn under such Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

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

Section 4.15

Limitation on Guarantees of Indebtedness by Restricted Subsidiaries

The Issuer shall not permit any of its Wholly-Owned Subsidiaries that are Restricted Subsidiaries (and non-Wholly-Owned Subsidiaries if such non-Wholly-Owned Subsidiaries guarantee other capital markets debt securities of the Issuer or any Guarantor), other than a Guarantor, a Foreign Subsidiary or a Receivables Subsidiary, to guarantee the payment of any Indebtedness of the Issuer unless:

(1) such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, providing for a Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Issuer:

(a) if the Senior Notes or such Guarantor’s Guarantee is subordinated in right of payment to such Indebtedness, the Guarantee under the supplemental indenture shall be subordinated to such Restricted Subsidiary’s guarantee with respect to such Indebtedness substantially to the same extent as the Senior Notes are subordinated to such Indebtedness; and

(b) if such Indebtedness is by its express terms subordinated in right of payment to the Senior Notes, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Senior Notes; and

(2) such Restricted Subsidiary waives, and shall not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against the Issuer or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee;

provided that this Section 4.15 shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary.

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

Section 6.02

Acceleration.

If any Event of Default (other than an Event of Default specified in clause (6) or (7) of Section 6.01(a) hereof) occurs and is continuing under this Indenture, the Trustee or the Holders of at least 30% in aggregate principal amount of the Senior Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Senior 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 Senior 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 Senior Notes.

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

The Holders of at least a majority in aggregate principal amount of the Senior Notes by written notice to the Trustee may on behalf of all of the Holders waive any existing Default and its consequences under this Indenture except a continuing Default in the payment of interest on, premium, if any, or the principal of any Senior Note (held by a non consenting Holder) and rescind any acceleration with respect to the Senior Notes and its consequences (so long as such rescission would not conflict with any judgment of a court of competent jurisdiction).

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 Senior Notes or to enforce the performance of any provision of the Senior Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Senior Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Senior 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.

The Holders of at least a majority in aggregate principal amount of the Senior Notes by notice to the Trustee may on behalf of the Holders of all of the Senior Notes waive any existing Default and its consequences hereunder, except a continuing Default in the payment of the principal of, premium, if any, Additional Interest, if any, or interest on, any Senior Note held by a non-consenting Holder and rescind any acceleration with respect to the Senior Notes and its consequences (provided such rescission would not conflict with any judgment of a court of competent jurisdiction); provided, subject to Section 6.02 hereof, that the Holders of a majority in aggregate principal amount of the then outstanding Senior Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05

Control by Majority.

The Holders of at least a majority in aggregate principal amount of the Senior 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 Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder of a Senior Note or that would involve the Trustee in personal liability.

Section 6.06

Limitation on Suits.

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

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

(2) Holders of at least 30% in aggregate principal amount of the Senior Notes have requested the Trustee to pursue the remedy;

(3) Holders of the Senior Notes have offered the Trustee reasonable security or indemnity 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) the Holders of at least a majority in aggregate principal amount of the Senior Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

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

Section 6.07

Rights of Holders of Senior Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Senior Note to receive payment of principal, premium, if any, and Additional Interest, if any, and interest on the Senior Note, on or after the respective due dates expressed in the Senior Note (including in connection with an Asset Sale Offer or 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 Additional Interest, if any, and interest remaining unpaid on the Senior 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 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 Senior 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 Senior Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.12

Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Senior Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Senior 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 authorize or consent to or accept or adopt on behalf of any Holder any Plan of Reorganization, arrangement, adjustment or composition affecting the Senior Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.13

Priorities.

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

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

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

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

Section 6.14

Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.14 does not apply to a suit by the Trustee, a suit by a Holder of a Senior Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Senior Notes.

Section 7.01

Duties of Trustee.

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

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.

The obligations of the Issuer under this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee.

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

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

The Trustee may resign at any time by giving 30 days prior written notice of such resignation to the Issuer and be discharged from the trust hereby created by so notifying the Issuer. The Holders of a majority in principal amount of the then outstanding Senior Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

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

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

Section 7.09

Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02

Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Senior Notes and Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Senior Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Senior Notes and this 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:

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

104

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

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

(d) this Section 8.02.

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

Section 8.03

Covenant Defeasance.

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuer and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 hereof and clauses (3) and (4) of Section 5.01(a), Sections 5.01(c) and 5.01(d) hereof with respect to the outstanding Senior Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“Covenant Defeasance”), and the Senior 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 Senior Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Senior 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 Indenture and such Senior 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)(4), 6.01(a)(5), 6.01(a)(6) (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are Significant Subsidiaries), 6.01(a)(7) (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are Significant Subsidiaries) and 6.01(a)(8) hereof shall not constitute Events of Default.

Section 8.04

Conditions to Legal or Covenant Defeasance.

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

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the Senior Notes:

(1) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Senior Notes, cash in U.S. dollars, Government Securities, or a combination

105

thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest due on the Senior Notes on the stated maturity date or on the redemption date, as the case may be, of such principal, premium, if any, or interest on such Senior Notes and the Issuer must specify whether such Senior Notes are being defeased to maturity or to a particular redemption date;

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

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

(b) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

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

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

(4) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

(6) the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject to customary assumptions and exclusions following the deposit, the trust funds will not be subject to the effect of Section 547 of Title 11 of the United States Code;

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

106

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

Section 8.05

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

Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Senior Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Senior Notes and this 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 Senior Notes of all sums due and to become due thereon in respect of principal, premium and Additional Interest, if any, 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 Senior Notes.

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

Section 8.06

Repayment to Issuer.

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

Section 8.07

Reinstatement.

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

107

(2) to provide for uncertificated Senior Notes of such series in addition to or in place of certificated Senior Notes;

(3) to comply with Section 5.01 hereof;

(11) to conform the text of the Indenture, Guarantees or the Senior Notes to any provision of the “Description of the Notes” section of the Offering Memorandum to the extent such provision in such “Description of the Notes” section was intended to be a verbatim recitation of a provision of this Indenture, Guarantee or Senior Notes;

(12) to make any amendment to the provisions of this Indenture relating to the transfer and legending of Senior Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of the Senior Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in Senior Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of Holders to transfer Senior Notes;

108

(13) to mortgage, pledge, hypothecate or grant any other Lien in favor of the Trustee for the benefit of the Holders of the Senior Notes, as security for the payment and performance of all or any portion of the Obligations, in any property or assets; or

(14) in the event that PIK Notes are issued in certificated form, to make appropriate amendments to this Indenture to reflect an appropriate minimum denomination of certificated PIK Notes and establish minimum redemption amounts for certificated PIK Notes.

In addition, notwithstanding Section 9.02 of this Indenture, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture at any time after the Issue Date, without the consent of any Holder, to provide for the issuance of Additional Senior Notes in accordance with this Indenture.

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 receipt by the Trustee of the documents described in Sections 7.02 and 12.04 hereof, the Trustee shall join with the Issuer and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, no Opinion of Counsel shall be required in connection with the addition of a Guarantor under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto, and delivery of an Officer’s Certificate.

Section 9.02

With Consent of Holders of Senior Notes.

Except as provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Senior Notes and the Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the Senior Notes (including Additional Senior Notes) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Senior 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 and Additional Interest, if any, or interest on the Senior Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Senior Notes or the Guarantees may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the Senior Notes (including Additional Senior Notes) then outstanding voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Senior Notes) other than Senior Notes beneficially owned by the Issuer or its Affiliates; provided, however, that if any amendment, waiver or other modification will affect only the Senior Cash Pay Notes or Senior Toggle Notes, only the consent of the Holders of at least a majority in principal amount of the then outstanding Senior Cash Pay Notes or Senior Toggle Notes (and not the consent of at least a majority of all Senior Notes), as the case may be, shall be required. Section 2.08 hereof and Section 2.09 hereof shall determine which Senior 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 at least a majority in aggregate

109

principal amount of the Senior Notes as aforesaid, and upon receipt by the Trustee of the documents described in Sections 7.02 and 12.04 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 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 the Senior 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.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer shall mail to the Holders of Senior 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 Senior Notes, an amendment or waiver under this Section 9.02 may not (with respect to any Senior Notes held by a non-consenting Holder):

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

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

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

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

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

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

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

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

110

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

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

Section 9.03

Compliance with Trust Indenture Act.

Every amendment or supplement to this Indenture or the Senior 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 Senior Note is a continuing consent by the Holder of a Senior Note and every subsequent Holder of a Senior Note or portion of a Senior Note that evidences the same debt as the consenting Holder’s Senior Note, even if notation of the consent is not made on any Senior Note. However, any such Holder of a Senior Note or subsequent Holder of a Senior Note may revoke the consent as to its Senior Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. Except as provided in the last paragraph of Section 9.02 hereof, an amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every 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.

Section 9.05

Notation on or Exchange of Senior Notes.

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

Failure to make the appropriate notation or issue a new Senior 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 12.04 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 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

111

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 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 of Senior Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Senior 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 10

GUARANTEES

Section 10.01

Guarantee.

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

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Senior Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Senior 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 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 Guarantee shall not be discharged except by complete performance of the obligations contained in the Senior Notes and this Indenture.

Each 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 10.01.

If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors 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.

112

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

Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the 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 Senior Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Senior Notes or Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Senior Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

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

The Guarantee issued by any Guarantor shall be a senior unsecured obligation of such Guarantor. The Guarantees shall rank equally in right of payment with all existing and future Senior Indebtedness of the Guarantor. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each Guarantor.

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

Section 10.02

Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Senior Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Guarantee not

113

constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed obligations under this Indenture to a contribution from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of such payment determined in accordance with GAAP.

Section 10.03

Execution and Delivery.

To evidence its Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by an Officer or person holding an equivalent title.

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

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

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

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

Section 10.04

Subrogation.

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

Section 10.05

Benefits Acknowledged.

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

Section 10.06

Release of Guarantees

A Guarantee by a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Issuer or the Trustee is required for the release of such Guarantor’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 this Indenture;

114

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

ARTICLE 11

SATISFACTION AND DISCHARGE

Section 11.01

Satisfaction and Discharge.

This Indenture shall be discharged and shall cease to be of further effect as to all Senior Notes, when either:

(1) all Senior Notes theretofore authenticated and delivered, except lost, stolen or destroyed Senior Notes which have been replaced or paid and Senior Notes for whose payment money has theretofore been deposited in trust, have been delivered to the Trustee for cancellation; or

(2) (A) all Senior Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making of a notice of redemption or otherwise, shall become due and payable within one year or may be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Senior Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as shall be sufficient without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Senior Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(B) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect to this Indenture or the Senior Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit, and such deposit will not result in a breach or violation of, or constitute a default, under any material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing

115

funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and in each case, the granting of Liens in connection therewith);

(D) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Senior Notes at maturity or the Redemption Date, as the case may be.

In addition, the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subclause (A) of clause (2) of this Section 11.01, the provisions of Section 11.02 and Section 8.06 hereof shall survive.

Section 11.02

Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Senior Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium and Additional Interest, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 11.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s and any Guarantor’s obligations under this Indenture and the Senior Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof; provided that if the Issuer has made any payment of principal of, premium and Additional Interest, if any, or interest on any Senior Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Senior Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

[Back of Senior Cash Pay Note]

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

(1) INTEREST. Energy Future Holdings Corp., a Texas corporation (the “Issuer”), promises to pay interest on the principal amount of this Senior Cash Pay Note at 10.875% per annum from October 31, 2007 until maturity and shall pay Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuer will pay interest and Additional Interest, if any, 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”) without interest accruing on the amount then so payable from such day that is not a Business Day until such Business Day. Interest on the Senior Cash Pay 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. 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 Senior Cash Pay Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the interest rate on the Senior Cash Pay 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 Senior Cash Pay Notes and Additional Interest, if any, to the Persons who are registered Holders of Senior Cash Pay Notes at the close of business on the April 15 or October 15 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Senior Cash Pay Notes are canceled after such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payment of interest and Additional Interest, if any, 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 and Additional Interest, if any, on, all Global Notes and all other Senior Cash Pay 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, The Bank of New York, the Trustee under the Indenture, 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) INDENTURE. The Issuer issued the Senior Cash Pay Notes under an Indenture, dated as of October 31, 2007 (the “Indenture”), among the Issuer, the Guarantors named therein and the Trustee. This Senior Cash Pay Note is one of a duly authorized issue of notes of the Issuer designated as its 10.875% Senior Notes due 2017. The Issuer shall be entitled to issue Additional Senior Cash Pay Notes pursuant to Sections 2.01 and 4.09 of the Indenture. The Senior Cash Pay Notes (including any Exchange Notes issued in exchange therefor) and the Senior Toggle Notes issued under the Indenture (including any Exchange Notes issued in exchange therefor) (collectively, referred to herein as the “Senior Notes”) are separate series of Senior Notes, but shall be treated as a single class of securities under the Indenture, unless otherwise specified in the Indenture. The terms of the Senior Cash Pay Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Senior Cash Pay Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Senior Cash Pay Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

On and after the Redemption Date interest ceases to accrue on Senior Cash Pay Notes or portions thereof called for redemption.

(8) OFFERS TO REPURCHASE.

(a) If a Change of Control occurs, the Issuer shall make an offer (a “Change of Control Offer”) to each Holder to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Senior Cash Pay Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the right of Holders of Senior Cash Pay Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date. The Change of Control Offer shall be made in accordance with Section 4.14 of the Indenture.

(b) If the Issuer or any of its Restricted Subsidiaries consummates an Asset Sale, within ten 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 Senior 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 Senior 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 and Additional Interest, if any, to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Senior 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 Indenture. If the aggregate principal amount of Senior Notes or such Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Senior Notes and such Senior Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount of the Senior Notes or such Senior Indebtedness tendered.

(c) The Issuer may, at its option, make an Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale; provided that such Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million.

The Issuer need not exchange or register the transfer of any Senior Cash Pay Notes or portion of Senior Cash Pay Notes selected for redemption, except for the unredeemed portion of any Senior Cash Pay Notes being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Senior Cash Pay Notes for a period of 15 days before a selection of Senior Cash Pay Notes to be redeemed.

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

Holders may not enforce the Indenture, the Senior Notes or the Guarantees except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Senior Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Senior Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, Additional Interest, 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 then outstanding Senior Notes by notice to the Trustee may on behalf of the Holders of all of the Senior Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal of, premium, if any, Additional Interest, if any, or interest on, any of the Senior Notes held by a non-consenting Holder. The Issuer and each Guarantor (to the extent that such Guarantor is so required under the Trust Indenture Act) is required to deliver to the Trustee annually a statement regarding compliance with the 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.

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

(1) INTEREST. Energy Future Holdings Corp., a Texas corporation (the “Issuer”), promises to pay interest on the principal amount of this Senior Toggle Note at a rate per annum set forth below from October 31, 2007 until maturity and shall pay Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuer will pay interest and Additional Interest, if any, 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”) without interest accruing on the amount then so payable from such day that is not a Business Day until such Business Day. Interest on the Senior Toggle 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. 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 Senior Toggle Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Additional Interest, if any, (without regard to any applicable grace periods) from time to time on demand at the interest rate on the Senior Toggle Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Cash Interest on the Senior Toggle Notes will accrue at a rate of 11.250% per annum and be payable in cash. PIK Interest on the Senior Toggle Notes will accrue at a rate of 12.000% per annum and be payable (x) with respect to Senior Toggle Notes represented by one or more global notes registered in the name of, or held by, The Depository Trust Company (“DTC”) or its nominee on the relevant Record Date, by increasing the principal amount of the outstanding global Senior Toggle Note by an amount equal to the amount of PIK Interest for the applicable interest period (rounded up to the nearest $1,000) (or, if necessary, pursuant to the requirements of DTC or otherwise, to authenticate new global Senior Toggle Notes executed by the Issuer with such increased principal amounts) and (y) with respect to Senior Toggle Notes represented by certificated notes, by issuing PIK Notes in certificated form in an aggregate principal amount equal to the amount of PIK Interest for the applicable period (rounded up to the nearest whole dollar), and the Trustee will, at the request of the Issuer, authenticate and deliver such PIK Notes in certificated form for original issuance to the Holders on the relevant Record Date, as shown by the records of the register of Holders. In the event that the Issuer elects to pay Partial PIK Interest for any interest period, each Holder will be entitled to receive Cash Interest in respect of 50% of the principal amount of the Senior Toggle Notes held by such Holder on the relevant Record Date and PIK Interest in respect of 50% of the principal amount of the Senior Toggle Notes held by such Holder on the relevant Record Date. Following an increase in the principal amount of the outstanding global Senior Toggle Notes as a result of a PIK Payment, the global Senior Toggle Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in certificated form will be dated as of the applicable Interest Payment Date and will bear interest from and after such date. All Senior Toggle Notes issued pursuant to a PIK Payment will mature on November 1, 2017 and will be governed by, and subject to the terms, provisions and conditions of, the Indenture and shall have the same rights and benefits as the Senior Toggle Notes issued on the Issue Date.

[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 Energy Future Holdings Corp., a Texas corporation (the “Issuer”), and The Bank of New York, as trustee (the “Trustee”).

WITNESSETH

WHEREAS, each of the Issuer and the Guarantors (as defined in the Indenture referred to below) has heretofore executed and delivered to the Trustee an Indenture (the “Indenture”), dated as of October 31, 2007, providing for the issuance of an unlimited aggregate principal amount of 10.875% Senior Notes due 2017 and 11.250%/12.000% Senior Toggle Notes due 2017 (together, the “Senior Notes”);

WHEREAS, the 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 Senior Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Guarantee”); and

WHEREAS, pursuant to Section 9.01 of the 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 Senior Notes as follows:

1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees as follows:

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

(i) the principal of and interest, premium and Additional Interest, if any, on the Senior 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 Senior 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

D-1

(ii) in case of any extension of time of payment or renewal of any Senior Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors 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 Senior Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Senior 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) Except as set forth in Section 5 hereto, this Guarantee shall not be discharged except by complete performance of the obligations contained in the Senior Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts all obligations of a Guarantor under the 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 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 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 10.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to receive contribution

D-2

from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 10 of the 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.

(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 Senior Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Senior 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 Senior 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 unsecured obligation of such Guaranteeing Subsidiary, ranking equally in right of payment with all existing and future Senior Indebtedness of the Guaranteeing Subsidiary, will be effectively subordinated to all Secured Indebtedness of such Guaranteeing Subsidiary to the extent of the value of the collateral securing such indebtedness. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each Guarantor. The Senior Notes will be structurally subordinated to Indebtedness and other liabilities of Subsidiaries of the Issuer that do not Guarantee the Senior Notes, if any.
