18

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.

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.

19

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.

Each Global Note shall represent such of the outstanding Notes as shall be specified in the “Schedule of Exchanges of Interests in the Global Note” attached thereto and each shall provide that it shall represent up to the aggregate principal amount of Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby shall be made by the Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(c) [Reserved]

Except as described under Article 9 hereof, the Initial Notes offered by the Issuer and any Additional Notes subsequently issued under this Indenture shall 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 “Notes” for all purposes under this Indenture include any Additional Notes that are actually issued.

Section 2.02 Execution and Authentication.

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

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

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

On the Issue Date, the Trustee shall, upon receipt of a written order of the Issuer signed by an Officer (an “Issuer Authentication Order”), authenticate and deliver the Initial Notes.

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

(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 Note selected for redemption in whole or in part, except the unredeemed portion of any 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 Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or (C) to register the transfer of or to exchange a Note between a Record Date and the next succeeding Interest Payment Date.

Section 2.07 Replacement Notes.

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

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

Section 2.08 Outstanding Notes.

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

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

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

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

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, any 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 Notes that a Responsible Officer of the Trustee knows are so owned, shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Issuer or any obligor upon the Notes or any Affiliate of the Issuer or of such other obligor.

Section 2.10 Temporary Notes.

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

52

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

Section 2.11 Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all cancelled Notes shall be delivered to the Issuer upon the Issuer’s written request. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Cash Interest.

If the Issuer defaults in a payment of cash interest on the 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 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 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 Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

Section 2.13 CUSIP and ISIN Numbers.

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

53

Section 2.14 Listing.

The Issuer shall promptly notify the Trustee when the Notes become listed or cease to be listed on any U.S. national or regional securities exchange.

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

(c) The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; no Notes of $2,000 or less can be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of 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 Notes called for redemption or purchase also apply to portions of 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 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 12 hereof. Except as set forth in Sections 3.04, 3.07(c) and 3.07(d) hereof, notices of redemption may not be conditional.

54

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

(a) the Redemption Date;

(b) the redemption price;

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

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

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

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

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

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

(i) if in connection with a redemption pursuant to Section 3.07(c) or Section 3.07(d) hereof, any condition to such redemption.

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 two Business Days before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this Section 3.03 (unless a shorter notice shall be agreed to by the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price (except as provided for in Sections 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 Note designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes called for redemption.

Section 3.05 Deposit of Redemption or Purchase Price.

Prior to 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 on all 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 on, all Notes to be redeemed or purchased.

55

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

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Issuer shall issue and, upon receipt of an Issuer Authentication Order, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided that each new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Issuer Authentication Order and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new Note.

Section 3.07 Optional Redemption.

(a) Notes Make Whole Redemption. At any time prior to October 15, 2014, the Issuer may redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, the date of redemption (the “Redemption Date”), subject to the right of Holders of Notes of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date.

Payment for any Notes so purchased shall be made in the same manner as interest payments are made.

(c) If the Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest up to but excluding the Purchase Date, shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer or the Collateral Asset Sale Offer, as applicable.

Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof.

(6) Indebtedness arising from agreements of the Issuer or its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or a Subsidiary, other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or a Subsidiary for the purpose of financing such acquisition; provided, however, that such Indebtedness is not reflected on the balance sheet of the Issuer, or any of its Restricted Subsidiaries (contingent obligations referred to in a footnote to financial statements and not otherwise reflected on the balance sheet shall not be deemed to be reflected on such balance sheet for purposes of this clause (6));

(7) Indebtedness of the Issuer to a Restricted Subsidiary; provided that any such Indebtedness (other than intercompany loans from TCEH and its Subsidiaries required to be unsubordinated by the terms of any Indebtedness of TCEH or such Subsidiaries) owing to a Restricted Subsidiary that is not a Guarantor is expressly subordinated in right of payment to the Notes; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Issuer or another Restricted Subsidiary) shall be deemed, in each case, to be an incurrence of such Indebtedness not permitted by this clause (7);

(8) Indebtedness of a Restricted Subsidiary to the Issuer or another Restricted Subsidiary; provided that if a Guarantor incurs such Indebtedness to a Restricted Subsidiary that is not a Guarantor (other than intercompany loans from TCEH and its Subsidiaries required to be unsubordinated by the terms of any Indebtedness of TCEH or such Subsidiaries), such Indebtedness is expressly subordinated in right of payment to the Guarantee of the Notes of such Guarantor; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event which results in any Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such Indebtedness (except to the Issuer or another Restricted Subsidiary) shall be deemed, in each case, to be an incurrence of such Indebtedness not permitted by this clause (8);

(13) the incurrence or issuance by the Issuer or any Restricted Subsidiary of Indebtedness, Disqualified Stock or Preferred Stock which serves to refund or refinance any Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted Subsidiary incurred as permitted under Section 4.09(a) hereof and clauses (2), (3), (4) and (12)(a) of this Section 4.09(b), this clause (13) and clause (14) of this Section 4.09(b) or any Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted Subsidiary issued to so refund or refinance such Indebtedness, Disqualified Stock or Preferred Stock of the Issuer or any Restricted Subsidiary including additional Indebtedness, Disqualified Stock or Preferred Stock incurred to pay premiums (including reasonable tender premiums), defeasance costs and fees in connection therewith (the “Refinancing Indebtedness”) prior to its respective maturity; provided, however, that such Refinancing Indebtedness:

(a) has a Weighted Average Life to Maturity at the time such Refinancing Indebtedness is incurred which is not less than the remaining Weighted Average Life to Maturity of the Indebtedness, Disqualified Stock or Preferred Stock being refunded or refinanced,

(b) to the extent such Refinancing Indebtedness refinances (i) Indebtedness subordinated or pari passu to the Notes or any Guarantee thereof, such Refinancing Indebtedness is subordinated or pari passu to the Notes or the Guarantee at least to the same extent as the Indebtedness being refinanced or refunded or (ii) Disqualified Stock or Preferred Stock, such Refinancing Indebtedness must be Disqualified Stock or Preferred Stock, respectively, and

73

(b) in the case of an acquisition by or merger with TCEH or any of its Restricted Subsidiaries, either (A) TCEH would be permitted to incur at least $1.00 of additional Indebtedness pursuant to clause (ii) of the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof, or (B) such Fixed Charge Coverage Ratio of TCEH and its Restricted Subsidiaries is greater than immediately prior to such acquisition or merger;

(17) (a) any guarantee by the Issuer or a Restricted Subsidiary of Indebtedness or other obligations of any Restricted Subsidiary, so long as the incurrence of such Indebtedness incurred by such Restricted Subsidiary is permitted under the terms of this Indenture, or (b) any guarantee by a Restricted Subsidiary of Indebtedness of the Issuer; provided that such guarantee is incurred in accordance with Section 4.15 hereof;

(18) Indebtedness of the Issuer or any of its Restricted Subsidiaries consisting of (i) the financing of insurance premiums or (ii) take-or-pay obligations contained in supply arrangements, in each case, incurred in the ordinary course of business; and

(19) Indebtedness consisting of Indebtedness issued by the Issuer or any of its Restricted Subsidiaries to current or former officers, directors and employees thereof, their

74

respective estates, spouses or former spouses, in each case to finance the purchase or redemption of Equity Interests of the Issuer or any direct or indirect parent company of the Issuer to the extent described in clause (4) of Section 4.07(b) hereof.

(c) For purposes of determining compliance with this Section 4.09:

(1) in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the criteria of more than one of the categories of permitted Indebtedness, Disqualified Stock or Preferred Stock described in clauses (1) through (19) of Section 4.09(b) hereof or is entitled to be incurred pursuant to Section 4.09(a) hereof, the Issuer, in its sole discretion, shall classify or reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and shall only be required to include the amount and type of such Indebtedness, Disqualified Stock or Preferred Stock in one of the above clauses; and

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

provided that all Indebtedness outstanding under the TCEH Senior Secured Facilities on the Issue Date shall be treated as incurred on the Issue Date under clause (1) of Section 4.09(b) 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 in this Section 4.09 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 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) (A) 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) except in the case of an Asset Sale of Collateral, any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the footnotes thereto) of the Issuer or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes 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; provided that the aggregate fair market value of Designated Non-cash Consideration received by EFIH after the Issue Date in respect of Asset Sales of Collateral shall not exceed $400.0 million,

shall be deemed to be cash for purposes of this clause (a)(2)(A) and for no other purpose; and

(B) any consideration received by EFIH from an Asset Sale of Collateral shall be concurrently pledged as Collateral for the benefit of the Holders of the Notes and holders of the other Secured Debt Obligations; provided that to the extent such consideration is received by EFIH in cash, it shall be held in an Asset Sale Cash Collateral Account pending the application of such cash consideration pursuant to this Section 4.10.

76

(b) In respect of Net Proceeds received by the Issuer or any Restricted Subsidiary from Asset Sales (other than an Asset Sale of Collateral or other Oncor-related Assets), within 450 days after the receipt of any Net Proceeds of any such 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 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 in Section 4.10(d) hereof for an Asset Sale Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any;

(C) Obligations under any Existing Notes with a maturity prior to October 15, 2019; 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 such Existing Notes pursuant to this subclause (C) following the Issue 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 shall 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 shall 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;

77

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 shall 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.

(c) Notwithstanding Section 4.10(b) hereof, to the extent that regulatory approval is necessary for an asset purchase 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.

(d) Any Net Proceeds from Asset Sales (other than Asset Sales of Collateral or other Oncor-related Assets) that are not invested or applied as provided and within the time period set forth in Section 4.10(b) hereof shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $200.0 million, the Issuer and/or any of its Restricted Subsidiaries shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any Senior Indebtedness, to the holders of such Senior Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Senior Indebtedness that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer and/or any of its Restricted Subsidiaries shall commence an Asset Sale Offer with respect to Excess Proceeds within 10 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.

(e) To the extent that the aggregate amount of Notes and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer and/or any of its Restricted Subsidiaries may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in this Indenture. If the aggregate principal amount of Notes or the Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Notes and such Senior Indebtedness shall be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered. Additionally, the Issuer and/or any of its Restricted Subsidiaries may, at its/their option, make an Asset Sale Offer using proceeds from any Asset Sale (other than Asset Sales of Collateral or other Oncor-related Assets) 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 Notes shall not be deemed Excess Proceeds.

(f) In respect of Net Proceeds received by the Issuer or any Restricted Subsidiary (including EFIH) from Asset Sales of Collateral or other Oncor-related Assets, within 450 days after the receipt by the Issuer or any Restricted Subsidiary of any Net Proceeds of any such Asset Sale, the Issuer or such Restricted Subsidiary shall be required to deposit the Net Proceeds from such Asset Sale into an Asset Sale Cash Collateral Account to be held solely for the purpose of repayment of principal, premium, if any, and interest on, and/or to repay, prepay or repurchase, the Notes and other Parity Lien Obligations as described in the following clauses (1) and (2),

78

(1) to repay or prepay Parity Lien Debt (other than the Notes) (and, in the case of revolving loans and other similar obligations, permanently reduce the commitment thereunder) on a pro rata basis, but only up to an aggregate principal amount equal to such Net Proceeds to be used to repay Indebtedness pursuant to this clause (1) multiplied by a fraction, the numerator of which is the aggregate outstanding principal amount of such Parity Lien Debt and the denominator of which is the aggregate outstanding principal amount of all Parity Lien Debt (including the Notes), in each case based on amounts outstanding on the date of closing of such Asset Sale; provided that the Issuer shall equally and ratably reduce Obligations under the Notes as provided in Section 3.07 hereof, through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth in Section 4.10(h) hereof for a Collateral Asset Sale Offer) to all Holders to purchase their Notes at 100% of the principal amount thereof plus the amount of accrued and unpaid interest, if any; or

(2) to repay or repurchase any EFIH Notes or other Parity Lien Debt of EFIH.

(g) Notwithstanding Section 4.10(f) hereof, in the event that regulatory approval is necessary for an Investment in any Oncor Subsidiary, 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(f) hereof.

(h) Any Net Proceeds from Asset Sales of Collateral or other Oncor-related Assets that are not invested or applied as provided and within the time period set forth in Section 4.10(f) hereof shall be deemed to constitute “Collateral Excess Proceeds.” When the aggregate amount of Collateral Excess Proceeds exceeds $200.0 million, the Issuer and/or any of its Restricted Subsidiaries shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any Parity Lien Debt, to the holders of such Parity Lien Debt (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of the Notes and such Parity Lien Debt that is a minimum of $2,000 or an integral multiple of $1,000 in excess thereof that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. The Issuer and/or any of its Restricted Subsidiaries shall commence a Collateral Asset Sale Offer with respect to Collateral Excess Proceeds within 10 Business Days after the date that Collateral Excess Proceeds exceed $200.0 million by mailing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee.

(i) To the extent that the aggregate amount of Notes and such Parity Lien Debt tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, the Issuer and/or any of its Restricted Subsidiaries may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other covenants contained in this Indenture and the terms of such Parity Lien Debt. If the aggregate principal amount of Notes or the Parity Lien Debt surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, the Notes and such Parity Lien Debt shall be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Parity Lien Debt tendered. Additionally, the Issuer and/or any of its Restricted Subsidiaries may, at its/their option, make a Collateral Asset Sale Offer using proceeds from any Asset Sale of Collateral or other Oncor-related Assets at any time after consummation of such Asset Sale; provided that such Collateral Asset Sale Offer shall be in an aggregate amount of not less than $25.0 million. Upon consummation of such Collateral Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed Collateral Excess Proceeds and the Issuer and its Restricted Subsidiaries may use any remaining Net Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture.

79

(j) 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; provided, however, that any Net Proceeds that represent proceeds of Collateral or other Oncor-related Assets shall be deposited and held in an Asset Sale Cash Collateral Account pending final application thereof in accordance with this Section 4.10. For the avoidance of doubt, “final application” of Net Proceeds that represent proceeds from the sale of Collateral or other Oncor-related Assets includes, without limitation, the consummation of a Collateral Asset Sale Offer.

(k) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to an Asset Sale Offer or a Collateral Asset Sale Offer.

except that the foregoing shall not apply to (a) Liens securing Indebtedness permitted to be incurred pursuant to clause (2) of Section 4.09(b) hereof; provided that the Notes or any related Guarantee are secured on at least an equal and ratable basis as such Indebtedness, (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) hereof 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

82

is being made shall occur would be no greater than 5.0 to 1.0.

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 Notes as described under Section 3.07 hereof and shall redeem all of the outstanding Notes pursuant thereto, the Issuer shall make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to the date of purchase, subject to the right of Holders of the 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 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 Notes properly tendered pursuant to such Change of Control Offer shall be accepted for payment by the Issuer;

83

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

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

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

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

(6) that Holders shall be entitled to withdraw their tendered Notes and their election to require the Issuer to purchase such 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 Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

The unpurchased portion of the 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 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 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.

Any proceeds received by the Issuer or its Restricted Subsidiaries from a sale, conveyance or disposition of Collateral or other Oncor-related Assets that constitutes a Change of Control shall be subject to a perfected security interest for the benefit of the holders of the Secured Debt Obligations until consummation of the Change of Control Offer pursuant to this Section 4.14.

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

84

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

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

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

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

(a) if the 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 Notes are subordinated to such Indebtedness; and

(b) if such Indebtedness is by its express terms subordinated in right of payment to the 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 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;

ARTICLE 5

SUCCESSORS

Section 5.01 Merger, Consolidation, or Sale of All or Substantially All Assets.

(a) The Issuer shall not consolidate or merge with or into or wind up into (whether or not the Issuer is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless:

(1) the Issuer is the surviving corporation or the Person formed by or surviving any such consolidation, wind-up or merger (if other than the Issuer) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the jurisdiction of organization of the Issuer or the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (such Person, as the case may be, being herein called the “Successor Company”);

89

(2) the Successor Company, if other than the Issuer, expressly assumes all the obligations of the Issuer under the Notes, this Indenture and the Security Documents, to the extent the Issuer is a party thereto, pursuant to a supplemental indenture or other document or instrument in form reasonably satisfactory to the Trustee;

(3) immediately after such transaction, no Default exists;

(4) immediately after giving pro forma effect to such transaction and any related financing transactions (including, without limitation, any transaction the proceeds of which are applied to reduce the Indebtedness of the Successor Company or the Issuer, as the case may be), as if such transactions had occurred at the beginning of the applicable four-quarter period,

(A) the Successor Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to clause (i) of the Fixed Charge Coverage Ratio test set forth in Section 4.09(a) hereof, or

(B) such Fixed Charge Coverage Ratio for the Successor Company and its Restricted Subsidiaries would be greater than such ratio for the Issuer and its Restricted Subsidiaries immediately prior to such transaction;

(5) each Guarantor, unless it is the other party to the transactions described above, in which case clause (1)(B) of Section 5.01(d) hereof shall apply, shall have by a supplemental indenture confirmed that its Guarantee and any Security Documents to which it is a party shall apply to such Person’s obligations under this Indenture and the Notes; and

(6) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such consolidation, wind-up, merger or transfer and such supplemental indenture, if any, comply with this Indenture and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture shall comply with the applicable provisions of this Indenture;

provided, that for the purposes of this Section 5.01 only, neither (A) the first to occur of a Permitted Asset Transfer or a TCEH Transfer (excluding a Permitted Asset Transfer consisting of a merger of EFIH with and into the Issuer for the purpose of determining the first to occur of a Permitted Asset Transfer or a TCEH Transfer) nor (B) a transaction meeting the requirements of the proviso to clause (3) under the definition of “Change of Control” shall be deemed to be a sale, assignment, transfer, conveyance or other disposition of all or substantially all of the properties or assets of the Issuer and its Subsidiaries under this Indenture. For the avoidance of doubt, (1) the Issuer may therefore consummate the first to occur of a Permitted Asset Transfer made in accordance with Section 4.16 hereof and a TCEH Transfer made in accordance with Section 4.17 hereof, in either case, without complying with this Section 5.01 (excluding a Permitted Asset Transfer consisting of a merger of EFIH with and into the Issuer for the purpose of determining the first to occur of a Permitted Asset Transfer or a TCEH Transfer), (2) the Issuer or any of its Restricted Subsidiaries may consummate a transaction meeting the requirements of the proviso to clause (3) under the definition of “Change of Control” without complying with this Section 5.01 and (3) the determination in the preceding proviso shall not affect the determination of what constitutes all or substantially all the assets of the Issuer and its Subsidiaries under any other agreement to which the Issuer is a party.

(b) Notwithstanding clauses (3) and (4) of Section 5.01(a) hereof,

(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 Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal and interest shall be due and payable immediately. The Trustee shall have no obligation to accelerate the Notes if and so long as a committee of its Responsible Officers in good faith determines acceleration is not in the best interest of the Holders of the Notes.

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

The Holders of at least a majority in aggregate principal amount of the 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 Note (held by a non consenting Holder) and rescind any acceleration with respect to the Notes and its consequences (so long as such rescission would not conflict with any judgment of a court of competent jurisdiction).

94

Section 6.03 Other Remedies.

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

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

Section 6.04 Waiver of Past Defaults.

The Holders of at least a majority in aggregate principal amount of the Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences hereunder, except a continuing Default in the payment of the principal, premium, if any, or interest on, any Note held by a non-consenting Holder and rescind any acceleration with respect to the 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 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 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 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 Note may pursue any remedy with respect to this Indenture or the Notes unless:

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

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

(3) Holders of the Notes have offered the Trustee security or indemnity reasonably satisfactory to it against any loss, liability or expense;

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

95

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

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer 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 clause (1) or (2) of Section 6.01(a) 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, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

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

Section 6.11 Delay or Omission Not Waiver.

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

96

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 Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes including the Guarantors), its creditors or its property and shall be entitled and empowered to participate as a member in any official committee of creditors appointed in such matter and to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any Plan of Reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any Plan of Reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.13 Priorities.

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

(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;

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

(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 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

97

litigant. This Section 6.14 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

ARTICLE 7

TRUSTEE

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.

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

(i) this paragraph does not limit the effect of clause (b) of this Section 7.01;

(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved in a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts; and

(iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to clauses (a), (b) and (c) of this Section 7.01.

98

Section 7.02 Rights of Trustee.

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(b) Before the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel.

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

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

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

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

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if

99

it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04 Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication.

Section 7.05 Notice of Defaults.

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

Section 7.06 Reports by Trustee to Holders of the Notes.

Within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by Trust Indenture Act Section 313(c).

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

Section 7.07 Compensation and Indemnity.

The Issuer and the Guarantors, jointly and severally, shall pay to the Trustee from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer and the Guarantors, jointly and severally, shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

100

The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee for, and hold the Trustee harmless against, any and all loss, damage, claims, liability or expense (including attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this Indenture against the Issuer or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, the Issuer or any Guarantor, or liability in connective with the acceptance, exercise or performance of any of its powers or duties hereunder). The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. 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.

Notwithstanding anything to the contrary in Section 4.12 hereof, to secure the payment obligations of the Issuer and the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

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

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

Section 7.08 Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08. The Trustee may resign 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 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;

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

(d) the Trustee becomes incapable of acting.

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

101

ARTICLE 8

LEGAL DEFEASANCE AND 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 Notes upon compliance with the conditions set forth below in this Article 8.

102

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

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

(c) the rights, powers, trusts, duties and immunities of the Trustee, and the 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 Collateral shall be released from the Lien securing the Notes as provided in Section 10.06 hereof, and 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, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20 and 4.21 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 Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04

103

hereof, clauses (3), (4), (5), (6) of Section 6.01(a) hereof, (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are Significant Subsidiaries), clause (7) of Section 6.01(a) hereof (solely with respect to Restricted Subsidiaries or groups of Restricted Subsidiaries that are Significant Subsidiaries), and clauses (8) and (9) of Section 6.01(a) hereof shall not constitute Events of Default.

(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 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 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

104

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 the Bankruptcy 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

(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 Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium and interest, but such money need not be segregated from other funds except to the extent required by law.

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

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, premium, if any, and interest on, any Note and remaining unclaimed for two years after such principal, and premium and 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 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.

105

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

(12) make any amendment to the provisions of this Indenture relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation, to facilitate the issuance and administration of the Notes; provided, however, that (i) compliance with this Indenture as so amended would not result in 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 Notes;

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 13.04 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 B hereto, and delivery of an Officer’s Certificate.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes, the Guarantees and the Security Documents relating to the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including Additional 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 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, premium and interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes, the Guarantees or the Security Documents relating to the Notes may be waived with

107

the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including Additional Notes) then outstanding voting as a single class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) other than Notes beneficially owned by the Issuer or its Affiliates. Section 2.08 hereof and Section 2.09 hereof shall determine which Notes are considered to be “outstanding” for the purpose 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 principal amount of the Notes as aforesaid, and upon receipt by the Trustee of the documents described in Sections 7.02 and 13.04 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 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 Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver.

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

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

(2) reduce the principal of or change the fixed final maturity of any such Note or alter or waive the provisions with respect to the redemption of such Notes (for the avoidance of doubt, the provisions contained in and relating to Section 3.09, Section 4.10 and Section 4.14 hereof are not redemptions of Notes);

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

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

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

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

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

108

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

(9) make any change to or modify the ranking provisions of this Indenture or the 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 Notes.

In addition, without the consent of at least a majority in aggregate principal amount of the Notes then outstanding, an amendment, supplement or waiver may not modify any Security Document relating to the Notes or the provisions of this Indenture dealing with the Security Documents or application of trust moneys in any manner materially adverse to the Holders other than in accordance with this Indenture and the Security Documents. Without the consent of at least 66²/₃% in aggregate principal amount of the Notes then outstanding, no amendment, supplement or waiver may modify the Security Documents to release all or substantially all of the Collateral securing the Notes. Without the consent of at least a majority in aggregate principal amount of the Notes then outstanding, no amendment, supplement or waiver may modify the Security Documents to release less than all or substantially all of the Collateral securing the Notes.

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

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

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

109

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

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer may not sign an amendment, supplement or waiver until the Board of Directors approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 13.04 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 exceptions, and complies with the provisions hereof (including Section 9.03 hereof). Notwithstanding the foregoing, no Opinion of Counsel shall be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture.

(5) in whole or in part as the result of a sale, transfer or other disposition in any transaction or other circumstance that is not prohibited by this Indenture or any applicable Secured Debt Document, at the time of, or immediately prior to, such sale, transfer or other disposition; provided that the Issuer shall have delivered an Officer’s Certificate to the Collateral Trustee certifying that such sale, transfer or other disposition does not violate the terms of this Indenture or any applicable Secured Debt Document.

Any certificate or opinion required by TIA §314(d) may be made by an Officer of the Issuer except in cases where TIA §314(d) requires that such certificate or opinion be made by an independent Person, which Person shall be an independent engineer, appraiser or other expert reasonably satisfactory to the Trustee. Notwithstanding anything to the contrary in this Section 10.06(b), the Issuer shall not be required to comply with all or any portion of TIA §314(d) if it determines, in good faith based on advice of counsel, that under the terms of TIA §314(d) and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of TIA §314(d) is inapplicable to released Collateral.

(c) To the extent applicable, the Issuer shall furnish to the Trustee and the Collateral Trustee, prior to each proposed release of Collateral pursuant to the Security Documents:

(1) enforce any of the terms of the Pledge Agreement; and

113

(2) collect and receive any and all amounts payable in respect of the Obligations of the Issuer hereunder.

(c) to consent to and direct the Collateral Trustee to perform its obligations under the Collateral Trust Agreement and the other Security Documents in respect of this Indenture, the Notes and the Guarantees.

Following and in accordance with the outcome of the applicable vote under this Indenture, the Trustee shall vote the total amount of the Notes as a block in respect of any vote under the Collateral Trust Agreement.

Section 10.11 Limitation on Duty of Trustee in Respect of Collateral; Indemnification.

(a) Beyond the exercise of reasonable care in the custody thereof, the Trustee shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Trustee shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any security interest in the Collateral. The Trustee shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Trustee in good faith.

(b) The Trustee shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of the Issuer to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Trustee shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Indenture, the Collateral Trust Agreement or the Security Documents by the Issuer, the Guarantors, the Secured Debt Representatives or the Collateral Trustee.

Section 10.12 Asset Sale Cash Collateral Account.

EFIH shall establish an Asset Sale Cash Collateral Account with the Collateral Trustee prior to any Asset Sale of Collateral or other Oncor-related Assets. The Collateral Trustee shall have sole dominion and control over any Asset Sale Cash Collateral Account and EFIH shall not have any right to withdraw funds from such Asset Sale Cash Collateral Account, except in accordance with the provisions of this Section 10.12 and Section 4.10 hereof. Any Asset Sale Cash Collateral Account shall be a securities account, as defined in the Uniform Commercial Code. The Collateral Trustee shall have no duty to inquire as to whether any funds deposited into an Asset Sale Cash Collateral Account are entitled to be so deposited and may conclusively assume that any such deposit by or on behalf of EFIH is proper. Prior to the occurrence of an Event of Default, EFIH shall have the right to direct investment of the funds held in an Asset Sale Cash Collateral Account or the liquidation of any such investments; provided, however, that any such investment shall only be permitted to the extent it is in the form of Cash Equivalents. Any investment direction or direction as to the liquidation of investments shall be in writing and signed by an Officer of EFIH, shall specify the particular investment to be made or liquidated and shall state that any investment or liquidation to be made in accordance with such direction is permitted hereby. The Collateral Trustee shall have no liability for any losses incurred in connection with the making or liquidation of any investment in accordance with this Section 10.12. Any investment in a fund referred to in clause (8) of the definition of “Cash Equivalents” may include money market funds with respect to which the Collateral Trustee or an Affiliate of the Collateral Trustee acts as an investment manager or advisor and with respect to which it may receive fees for the administration. The funds held in an Asset Sale Cash Collateral Account shall be released in accordance with clauses (1) and/or (2) of Section 4.10(f) hereof. Such funds shall also be released to repurchase Notes and to make related payments in connection with a Collateral Asset Sale Offer pursuant to Section 4.10(h) hereof and/or upon consummation of any Collateral Asset Sale Offer, whether or not any Collateral Excess Proceeds remain. EFIH shall deliver to the Trustee and the Collateral Trustee an Officer’s Certificate stating that such release was permitted by Section 4.10 hereof, except in the case of the payment of scheduled interest payments on the Notes and/or other Parity Lien Obligations in accordance with Section 4.10(f).

ARTICLE 11

GUARANTEES

Section 11.01 Guarantee.

Subject to this Article 11, each of the Guarantors hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: (a) the principal, premium, if any, and interest on, the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to 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 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 11.01.

If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, any of the Guarantors, or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or any of 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.

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

116

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

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

The Guarantees shall rank equally in right of payment with all existing and future Senior Indebtedness of the Guarantor. The Guarantees shall 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 11.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as shall, 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 11, result in the obligations of such Guarantor under its Guarantee not 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.

117

Section 11.03 Execution and Delivery.

To evidence its Guarantee set forth in Section 11.01 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 11.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

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

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

If required by Section 4.15 hereof, the Issuer shall cause any newly created or acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article 11, to the extent applicable.

Section 11.04 Subrogation.

Each Guarantor shall be subrogated to all rights of Holders of Notes against the Issuer in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 11.01 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 Notes shall have been paid in full.

Section 11.05 Benefits Acknowledged.

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

Section 11.06 Release of Guarantees.

(a) 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) any sale, exchange or transfer (by merger, wind-up, consolidation or otherwise) of the Capital Stock of such Guarantor (including any sale, exchange or transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary or sale of 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, except that the Guarantee by EFIH shall only be released and discharged as provided in Section 4.16 hereof;

(2) 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;

118

(3) the designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in compliance with Section 4.07 hereof and the definition of “Unrestricted Subsidiary” hereunder; or

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

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

(b) In the case of a Permitted Asset Transfer described in clause (2) of the definition of “Permitted Asset Transfer,” or a Permitted Asset Transfer described in clause (1) of the definition of “Permitted Asset Transfer” by way of merger, wind-up or consolidation, the Guarantee by EFIH shall be automatically released upon the consummation of such Permitted Asset Transfer in accordance with Section 4.16 hereof.

(c) The Guarantee by EFCH shall automatically be released in connection with a Permitted Asset Transfer made in accordance with Section 4.16 hereof other than a merger, wind-up or consolidation of EFIH into the Issuer where EFCH continues to be a Subsidiary of the Issuer.

SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

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

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

(2) — all 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 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 Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(A) 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 Notes shall have occurred and be continuing on the date of

119

such deposit or shall occur as a result of such deposit, and such deposit 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 such deposit and any similar and simultaneous deposit relating to other Indebtedness and in each case, the granting of Liens in connection therewith);

(B) the Issuer has paid or caused to be paid all sums payable by it under this Indenture; and

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 12.01, the provisions of Section 12.02 and Section 8.06 hereof shall survive.

Section 12.02 Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the 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 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 12.01 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 Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Issuer has made any payment of principal, premium, if any, and interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

[Back of 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 Note at 9.75% per annum from November 16, 2009 until maturity. The Issuer will pay interest semi-annually in arrears on April 15 and October 15 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 Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the date of issuance. The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the interest rate on the Notes; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the interest rate on the Notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2) METHOD OF PAYMENT. The Issuer will pay interest on the Notes to the Persons who are registered Holders of Notes at the close of business on the April 1 or October 1 (whether or not a Business Day), as the case may be, next preceding the Interest Payment Date, even if such Notes are canceled after such Record Date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal, premium, if any, and interest on, all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

(3) PAYING AGENT AND REGISTRAR. Initially, The Bank of New York Mellon Trust Company, N.A., 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 Notes under an Indenture, dated as of November 16, 2009 (the “Indenture”), among the Issuer, the Guarantors named therein and the Trustee. This Note is one of a duly authorized issue of notes of the Issuer designated as its 9.75% Senior Secured Notes due 2019 (the “Notes”). The Issuer shall be entitled to issue Additional Notes pursuant to Sections 2.01, 4.09 and 4.12 of the Indenture. The terms of the 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 Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms.

The Change of Control Offer shall be made in accordance with Section 4.14 of the Indenture.

To the extent that the aggregate amount of Notes, and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuer and/or any of its Restricted Subsidiaries may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture. If the aggregate principal amount of Notes or such Senior Indebtedness surrendered by such holders thereof exceeds the amount of Excess Proceeds, the Notes and such Senior Indebtedness will be purchased on a pro rata basis based on the accreted value or principal amount of the Notes or such Senior Indebtedness tendered.

Upon consummation of such Asset Sale Offer, any Net Proceeds not required to be used to purchase Notes shall not be deemed Excess Proceeds.

To the extent that the aggregate amount of Notes and such Parity Lien Debt tendered pursuant to a Collateral Asset Sale Offer is less than the Collateral Excess Proceeds, the Issuer and/or any of its Restricted Subsidiaries may use any remaining Collateral Excess Proceeds for general corporate purposes, subject to other covenants contained in the Indenture and the terms of such Parity Lien Debt.

A-5

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

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

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

(12) DEFAULTS AND REMEDIES. The Events of Default relating to the Notes are defined in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the then outstanding Notes may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture, the 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 Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal, premium, if any, or interest on, any of the 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 Business Days after becoming aware of any Default, to deliver to the Trustee a statement specifying such Default and what action the Issuer proposes to take with respect thereto.

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

A-6

(15) GOVERNING LAW. THE INDENTURE, THE NOTES AND THE GUARANTEES WILL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

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

The Issuer will furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Security Documents. Requests may be made to the Issuer at the following address:

[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 Mellon Trust Company, N.A., as trustee (the “Trustee”).

W I T N E S S E T H

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 November 16, 2009, providing for the issuance of an unlimited aggregate principal amount of 9.75% Senior Secured Notes due 2019 (the “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 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 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, fully and unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(i) the principal, premium, if any, and interest on the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

B-1

(ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same immediately. Each Guarantor (including the Guaranteeing Subsidiary) agrees that this is a guarantee of payment and not a guarantee of collection.

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

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

(d) Except as set forth in Section 5 hereof, this Guarantee shall not be discharged except by complete performance of the obligations contained in the 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, any of the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or any of 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 Guarantors 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 11.02 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

B-2

from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 11 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 Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantee, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

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

(l) This Guarantee shall be a senior [unsecured] [secured] obligation of such Guaranteeing Subsidiary, ranking equally in right of payment with all existing and future Senior Indebtedness of the Guaranteeing Subsidiary, [and will be effectively subordinated to all Secured Indebtedness of such Guaranteeing Subsidiary to the extent of the value of the assets securing such Indebtedness]. The Guarantees will be senior in right of payment to all existing and future Subordinated Indebtedness of each Guarantor. The Notes will be structurally subordinated to Indebtedness and other liabilities of Subsidiaries of the Issuer that do not Guarantee the Notes, if any.

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

3. EXECUTION AND DELIVERY. The Guaranteeing Subsidiary agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

4. MERGER, CONSOLIDATION OR SALE OF ALL OR SUBSTANTIALLY ALL ASSETS.

(a) The Guaranteeing Subsidiary may not consolidate or merge with or into or wind up into (whether or not the Issuer or Guaranteeing Subsidiary is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person except in compliance with Section 5.01(d) of the Indenture.

(b) Subject to certain limitations described in the Indenture, the Successor Person will succeed to, and be substituted for, the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee. Notwithstanding the foregoing, the Guaranteeing

B-3

Subsidiary may (i) merge into or transfer all or part of its properties and assets to another Guarantor or the Issuer, (ii) merge with an Affiliate of the Issuer solely for the purpose of reincorporating the Guaranteeing Subsidiary in the United States, any state thereof, the District of Columbia or any territory thereof or (iii) convert into a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor.

(1) (A) concurrently therewith, a corporate Wholly-Owned Subsidiary of the Issuer that is a Restricted Subsidiary organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof expressly assumes all the obligations of [EFIH Finance][ADD NAME OF CORPORATE CO-OBLIGOR IF NOT EFIH FINANCE] under the Notes and this Indenture pursuant to a supplemental indenture or other documents or instruments in form reasonably satisfactory to the Trustee; or

Such Pledgor is located (within the meaning of Section 9-307 of the UCC) and has its chief executive office in the states or jurisdictions set forth in Schedule I hereto. The information set forth in Schedule I hereto with respect to such Pledgor is true and accurate in all respects. Such Pledgor has not changed its name, location, chief executive office, type of organization, jurisdiction of organization or organizational identification number within the last five years from those set forth in Schedule I hereto except as disclosed in Schedule III hereto.

(b) All Security Collateral consisting of certificated securities and instruments has been delivered to the Collateral Trustee.

(c) Such Pledgor is the legal and beneficial owner of the Collateral of such Pledgor free and clear of any Lien, claim, option or right of others, except for the security interest created under this Agreement and Liens permitted in Section 10(a)(ii)(B). No effective financing statement or other instrument similar in effect covering all or any part of such Collateral or listing such Pledgor or any trade name of such Pledgor as debtor with respect to such Collateral is on file in any recording office, except such as may have been filed in favor of the Collateral Trustee relating to the Secured Debt Documents or as permitted in Section 10(a)(ii)(B).

(d) The Initial Pledged Equity is not represented by any certificate or interest and does not constitute an “uncertificated security” as defined in Article 8 of the UCC and as used in Article 9 of the UCC.

(e) The Pledged Equity pledged by such Pledgor hereunder has been duly authorized and validly issued and is fully paid and non-assessable. With respect to any Pledged Equity that is an “uncertificated security” (within the meaning of Article 8 of the UCC), such Pledgor has used its commercially reasonable efforts to cause the issuer thereof to agree in an authenticated record with such Pledgor and the Collateral Trustee that such issuer will comply with instructions with respect to such security originated by the Collateral Trustee without further consent of such Pledgor. If such Pledgor is an issuer of Pledged Equity, such Pledgor confirms that it has received notice of such security interest.

(f) The Initial Pledged Equity pledged by the Initial Pledgor (i) constitutes the percentage of the issued and outstanding Equity Interests of the issuer thereof indicated on Schedule II hereto and (ii) represents all Equity Interests directly held by the Initial Pledgor in any Oncor Subsidiary. As of the date hereof, there is no outstanding indebtedness owed to the Initial Pledgor by any Oncor Subsidiary. The Initial Pledgor has no Investments in any Oncor Subsidiary.

(iii) The Collateral Trustee will execute and deliver (or cause to be executed and delivered) to each Pledgor all such proxies and other instruments as such Pledgor may reasonably request for the purpose of enabling such Pledgor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest payments that it is authorized to receive and retain pursuant to paragraph (ii) above.

Section 13. The Collateral Trustee’s Duties. (a) The powers conferred on the Collateral Trustee hereunder are solely to protect the holders of Parity Lien Obligations’ interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Collateral Trustee shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any holder of Parity Lien Obligations has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Trustee shall be deemed to have exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property.

(b) Anything contained herein to the contrary notwithstanding, the Collateral Trustee may from time to time, when the Collateral Trustee deems it to be necessary, appoint one or more subagents (each a “Subagent”) for the Collateral Trustee hereunder with respect to all or any part of the Collateral. In the event that the Collateral Trustee so appoints any Subagent with respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by each Pledgor hereunder shall be deemed for purposes of this Agreement to have been made to such Subagent, in addition to the Collateral Trustee, for the ratable benefit of the holders of Parity Lien Obligations, as security for the Secured Obligations of such Pledgor, (ii) such Subagent shall automatically be vested, in addition to the Collateral Trustee, with all rights, powers, privileges, interests and remedies of the Collateral Trustee hereunder with respect to such Collateral, and (iii) the term “Collateral Trustee,” when used herein in relation to any rights, powers, privileges, interests and remedies of the Collateral Trustee with respect to such Collateral, shall include such Subagent; provided, however, that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly authorized in writing by the Collateral Trustee.

E-12

Section 14. Remedies. If any Event of Default shall have occurred and be continuing:

(a) Subject to Section 3.3(b) and Section 3.3(c) of the Collateral Trust Agreement, the Collateral Trustee may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a holder of Parity Lien Obligations upon default under the UCC (whether or not the UCC applies to the affected Collateral) and also may: (i) without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Trustee’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Trustee may deem commercially reasonable; and (ii) exercise any and all rights and remedies of any of the Pledgors under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, those set forth in Section 9-607 of the UCC. Each Pledgor agrees that, to the extent notice of sale shall be required by law, at least 10 days’ notice to such Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Trustee shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Trustee may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) Any cash held by or on behalf of the Collateral Trustee and all cash proceeds received by or on behalf of the Collateral Trustee in respect of any sale of, collection from, or other realization upon all or any part of the Collateral may, in the discretion of the Collateral Trustee, be held by the Collateral Trustee as collateral for, and/or then or at any time thereafter applied (after payment of any amounts payable to the Collateral Trustee pursuant to Section 15) in whole or in part by the Collateral Trustee for the ratable benefit of the holders of Parity Lien Obligations against, all or any part of the Secured Obligations, in the manner set forth in Section 3.4 of the Collateral Trust Agreement.

(c) All payments received by any Pledgor in respect of the Collateral shall be received in trust for the benefit of the Collateral Trustee, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Collateral Trustee in the same form as so received (with any necessary indorsement).

(a) No amendment or waiver of any provision of this Agreement, and no consent to any departure by any Pledgor herefrom, shall in any event be effective unless the same shall be in writing and signed by the Collateral Trustee, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of the Collateral Trustee or any other holder of Parity Lien Obligations to exercise, and no delay in exercising any right hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.

(b) Upon the execution and delivery, or authentication, by any Person of a pledge agreement supplement in substantially the form of Exhibit A hereto (each a “Pledge Agreement Supplement”), (i) such Person shall be referred to as an “Additional Pledgor” and shall be and become a Pledgor hereunder, and each reference in this Agreement and the other Secured Debt Documents to “Pledgor” shall also mean and be a reference to such Additional Pledgor, and each reference in this Agreement and the other Secured Debt Documents to “Collateral” shall also mean and be a reference to the Collateral of such Additional Pledgor, and (ii) the supplemental schedules I-III attached to each Pledge Agreement Supplement shall be incorporated into and become a part of and supplement Schedules I-III, respectively, hereto, and the Collateral Trustee may attach such supplemental schedules to such Schedules; and each reference to such Schedules shall mean and be a reference to such Schedules as supplemented pursuant to each Pledge Agreement Supplement.

Delivery by telecopier of an executed counterpart of any amendment or waiver of any provision of this Agreement or of any Pledge Agreement Supplement or Schedule hereto shall be effective as delivery of an original executed counterpart thereof.

Section 18. Continuing Security Interest. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until the latest of (i) the payment in full in cash of the Secured Obligations and (ii) October 15, 2019, (b) be binding upon each Pledgor, its successors and assigns and (c) inure, together with the rights and remedies of the Collateral Trustee hereunder, to the benefit of the holders of Parity Lien Obligations and their respective successors, transferees and assigns.

(b) Upon the payment in full in cash of the Secured Obligations, the pledge and security interest granted hereby shall terminate and all rights to the Collateral shall revert to the applicable Pledgor. Upon any such termination, the Collateral Agent will, at the applicable Pledgor’s expense, execute and deliver to such Pledgor such documents as such Pledgor shall reasonably request to evidence such termination.

(e) any change, restructuring or termination of the corporate structure or existence of any Issuer or any of its Subsidiaries;

(f) any failure of any Secured Party to disclose to any Pledgor any information relating to the business, condition (financial or otherwise), operations, performance, assets, nature of assets, liabilities or prospects of any Issuer or Pledgor now or hereafter known to such Secured Party (each Pledgor waiving any duty on the part of the Secured Parties to disclose such information);

(g) the failure of any other Person to execute this Agreement or any other Collateral Document, guaranty or agreement or the release or reduction of liability of any Pledgor or other grantor or surety with respect to the Secured Obligations; or

This Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Secured Obligations is rescinded or must otherwise be returned by any Secured Party or by any other Person upon the insolvency, bankruptcy or reorganization of any Issuer or otherwise, all as though such payment had not been made.

Section 23. Governing Law. (a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

(b) Each Pledgor hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Parity Lien Documents to which it is or is to be a party, or for recognition or enforcement of any judgment, and each Pledgor hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the extent permitted by law, in such federal court. Each Pledgor agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(1) they may freely seek and obtain relief granting a Junior Lien co-extensive in all respects with, but subordinated (as set forth in Section 2.3) to, all Liens granted in such Insolvency or Liquidation Proceeding to, or for the benefit of, the holders of Parity Lien Obligations; and

F-22

(2) they may freely seek and obtain any relief upon a motion for adequate protection (or any comparable relief), without any condition or restriction whatsoever, at any time after the Discharge of Parity Lien Obligations.

SECTION 2.9 Collateral Shared Equally and Ratably within Class. The parties to this Agreement agree that the payment and satisfaction of all of the Parity Lien Obligations and Junior Lien Obligations will be secured Equally and Ratably by the Liens established in favor of the Collateral Trustee for the benefit of the Secured Parties belonging to such Class. It is understood and agreed that nothing in this Section 2.9 is intended to alter the priorities among Secured Parties belonging to different Classes as provided in Section 2.3.

ARTICLE 3. OBLIGATIONS AND POWERS OF COLLATERAL TRUSTEE

SECTION 3.1 Undertaking of the Collateral Trustee.

(a) Subject to, and in accordance with, this Agreement, including without limitation Section 5.3, the Collateral Trustee will, as collateral trustee, for the benefit solely and exclusively of the current and future Secured Parties:

(1) accept, enter into, hold, maintain, administer and enforce all Security Documents, including all Collateral subject thereto, and all Liens created thereunder, perform its obligations under the Security Documents and protect, exercise and enforce the interests, rights, powers and remedies granted or available to it under, pursuant to or in connection with the Security Documents;

(2) take all lawful and commercially reasonable actions permitted under the Security Documents that it may deem necessary to protect or preserve its interest in the Collateral subject thereto and such interests, rights, powers and remedies;

(3) deliver and receive notices pursuant to the Security Documents;

(4) sell, assign, collect, assemble, foreclose on, institute legal proceedings with respect to, or otherwise exercise or enforce the rights and remedies of a secured party (including a mortgagee, trust deed beneficiary and insurance beneficiary or loss payee) with respect to the Collateral under the Security Documents and its other interests, rights, powers and remedies;

(5) remit as provided in Section 3.4 all cash proceeds received by the Collateral Trustee from the collection, foreclosure or enforcement of its interest in the Collateral under the Security Documents or any of its other interests, rights, powers or remedies;

F-23

(6) execute and deliver amendments to the Security Documents as from time to time authorized pursuant to Section 7.1 accompanied by an Officer’s Certificate to the effect that the amendment was permitted under Section 7.1; and

(7) release any Lien granted to it by any Security Document upon any Collateral if and as required by Section 4.1.

(b) Each party to this Agreement acknowledges and consents to the undertaking of the Collateral Trustee set forth in Section 3.1(a) and agrees to each of the other provisions of this Agreement applicable to the Collateral Trustee.

(c) Notwithstanding anything to the contrary contained in this Agreement, the Collateral Trustee will not commence any exercise of remedies or any foreclosure actions or otherwise take any action or proceeding against any of the Collateral (other than actions as necessary to prove, protect or preserve (but not enforce) the Liens securing the Secured Debt Obligations, subject to Section 5.9 of this Agreement) unless and until it shall have been directed by an Act of Required Debtholders, and then only in accordance with the provisions of this Agreement.

(d) The Collateral Trustee shall be under no obligation to exercise any of its rights or powers under this Agreement or any Security Document at the request or direction of any holder of Secured Debt unless such holders of Secured Debt shall have offered to the Collateral Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense.

SECTION 3.2 Release or Subordination of Liens. The Collateral Trustee will not release or subordinate any Lien of the Collateral Trustee or consent to the release or subordination of any Lien of the Collateral Trustee, except:

(a) as directed by an Act of Required Debtholders accompanied by an Officer’s Certificate to the effect that the release or subordination was permitted by each applicable Secured Debt Document;

(b) as required by Article 4;

(c) as ordered pursuant to applicable law under a final and nonappealable order or judgment of a court of competent jurisdiction; or

(d) for the subordination of the Junior Trust Estate and the Junior Liens to the Senior Trust Estate and the Parity Liens.

SECTION 3.3 Enforcement of Liens.

(a) If the Collateral Trustee at any time receives written notice stating that any event has occurred that constitutes a default under any Secured Debt Document entitling the Collateral Trustee to foreclose upon, collect or otherwise enforce its Liens thereunder, the Collateral Trustee will promptly deliver written notice thereof to each Secured Debt Representative. Thereafter, the Collateral Trustee will await direction by an Act of Required

F-24

Debtholders and will act, or decline to act, as directed by an Act of Required Debtholders, in the exercise and enforcement of the Collateral Trustee’s interests, rights, powers and remedies in respect of the Collateral or under the Security Documents or applicable law and, following the initiation of such exercise of remedies, the Collateral Trustee will act, or decline to act, with respect to the manner of such exercise of remedies as directed by an Act of Required Debtholders. Unless it has been directed to the contrary by an Act of Required Debtholders, the Collateral Trustee in any event may (but will not be obligated to) take or refrain from taking such action with respect to any default under any Secured Debt Document as it may deem advisable to preserve and protect the value of the Collateral.

(b) Regulatory approvals may be required in order to enforce the security interests against the Collateral and to dispose of an interest in, or operational control of, the Collateral that secures the EFIH Notes and EFIH’s guarantee of the EFH Notes.

The Collateral securing the EFIH Notes and EFIH’s guarantee of the EFH Notes will include all of the membership interests of Oncor Electric Delivery Holdings Company LLC (“Oncor Holdings”), which are held by EFIH. Pursuant to the Public Utility Regulatory Act (“PURA”), Texas Utilities Code §§39.262(l) and 39.915, an electric utility must obtain prior approval of the Public Utility Commission of Texas (“PUCT”) of any change in majority ownership, controlling ownership or operational control of Oncor Electric Delivery Company LLC (“Oncor”). As a result, prior to any foreclosure on the membership interests of Oncor Holdings, approval of the PUCT may be required for a change in ownership or control of Oncor Holdings. Pursuant to PURA §§39.262(m) and 39.915(b), the PUCT will approve such a transfer if it finds that the transaction is in the public interest. In making its determination, these sections of PURA provide that the PUCT will consider whether the transaction will adversely affect the reliability of service, availability of service or cost of service of Oncor. Therefore, in connection with any action taken to enforce the security against the Collateral, such approval may not be granted and, if it were to be granted, it is not known how long such approval would take to obtain. Even if the approval were granted to foreclose on the Collateral, then additional prior PUCT approval may also be required for any subsequent change in majority ownership, controlling ownership or operational control in the membership interests of Oncor Holdings.

(c) In addition, pursuant to the terms of an investor rights agreement, among EFH, Oncor Holdings, Oncor and Texas Transmission Investment LLC (“Texas Transmission”), the noncontrolling investor in Oncor, any transfer of the equity interests in Oncor Holdings to a third party, including as a result of any enforcement of the lien on the Collateral securing the EFIH Notes and EFIH’s guarantee of the EFH Notes, may be limited and give rise to a tag-along right of Texas Transmission to participate in that transfer on a pro rata basis, which may hinder the enforcement of the lien on the Collateral in a timely manner, if at all.

SECTION 3.4 Application of Proceeds.

(a) If any Collateral is sold or otherwise realized upon by the Collateral Trustee in connection with any foreclosure, collection or other enforcement of Parity Liens or Junior Liens granted to the Collateral Trustee in the Security Documents, the proceeds received by the Collateral Trustee from such foreclosure, collection or other enforcement will be distributed by the Collateral Trustee in the following order of application:

FIRST, to the payment of all amounts payable under this Agreement on account of the Collateral Trustee’s fees and any reasonable legal fees, costs and expenses or other liabilities of any kind incurred by the Collateral Trustee or any co-trustee or agent of the Collateral Trustee in connection with any Security Document;

F-25

SECOND, ratably to the respective Parity Lien Representatives for application, after payment of any fees and expenses (including but not limited to, attorney’s fees and expenses) of such Parity Lien Representative, to the payment of all outstanding Notes and other Parity Lien Debt and any other Parity Lien Obligations that are then due and payable in such order as may be provided in the relevant Parity Lien Documents in an amount sufficient to pay in full in cash all outstanding Notes and other Parity Lien Debt and all other Parity Lien Obligations that are then due and payable (including all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the relevant Parity Lien Documents, even if such interest is not enforceable, allowable or allowed as a claim in such proceeding, and including the discharge or cash collateralization (at the lower of (1) 105% of the aggregate undrawn amount and (2) the percentage of the aggregate undrawn amount required for release of Liens under the terms of the applicable Parity Lien Document) of all outstanding letters of credit constituting Parity Lien Debt);

THIRD, to the respective Junior Lien Representatives for application to the payment of all outstanding Junior Lien Debt and any other Junior Lien Obligations that are due and payable in such order as may be provided in the Junior Lien Documents in an amount sufficient to pay in full in cash all outstanding Junior Lien Debt and all other Junior Lien Obligations that are then due and payable (including all interest accrued thereon after the commencement of any Insolvency or Liquidation Proceeding at the rate, including any applicable post-default rate, specified in the Junior Lien Documents, even if such interest is not enforceable, allowable or allowed as a claim in such proceeding, and including the discharge or cash collateralization (at the lower of (1) 105% of the aggregate undrawn amount and (2) the percentage of the aggregate undrawn amount required for release of Liens under the terms of the applicable Junior Lien Document) of all outstanding letters of credit, if any, constituting Junior Lien Debt); and

FOURTH, any surplus remaining after the payment in full in cash of the amounts described in the preceding clauses will be paid to EFIH, or its successors or assigns, or as a court of competent jurisdiction may direct.

If any Junior Lien Representative or any holder of a Junior Lien Obligation collects or receives any proceeds in respect of any foreclosure, collection or other enforcement to which it was not entitled pursuant to the terms of the immediately preceding paragraphs, whether after the commencement of any Insolvency or Liquidation Proceeding or otherwise, such Junior Lien Representative or such holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral Trustee to be applied in accordance with the provisions set forth in the immediately preceding paragraphs. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, in trust for the benefit of the holders of the Parity Lien Obligations. These provisions will not apply to payments received by any holder of Junior Lien Obligations if such payments are not proceeds of, or the result of a realization upon, Collateral.

F-26

This Section 3.4(a) is intended for the benefit of, and will be enforceable as a third party beneficiary by, each present and future holder of Secured Debt Obligations, each present and future Secured Debt Representative and the Collateral Trustee as holder of Parity Liens and Junior Liens. The Secured Debt Representative of each future Series of Secured Lien Debt will be required to deliver a Collateral Trust Joinder, including a Lien Sharing and Priority Confirmation, to the Collateral Trustee and each other Secured Debt Representative as provided in Section 3.8 at the time of incurrence of such Series of Secured Lien Debt.

In connection with the application of proceeds pursuant to Section 3.4(a), except as otherwise directed by an Act of Required Debtholders, the Collateral Trustee may sell any non-cash proceeds for cash prior to the application of the proceeds thereof.

SECTION 3.5 Powers of the Collateral Trustee.

(a) The Collateral Trustee is irrevocably authorized and empowered to enter into and perform its obligations and protect, perfect, exercise and enforce its interest, rights, powers and remedies under the Security Documents and applicable law and in equity and to act as set forth in this Article 3 or as requested in any lawful directions given to it from time to time in respect of any matter by an Act of Required Debtholders, as applicable, in accordance with the provisions of this Agreement.

(b) No Secured Debt Representative or holder of Secured Debt Obligations will have any liability whatsoever for any act or omission of the Collateral Trustee.

SECTION 3.6 Documents and Communications. The Collateral Trustee will permit each Secured Debt Representative and each holder of Secured Debt Obligations upon reasonable written notice from time to time to inspect and copy, at the cost and expense of the party requesting such copies, any and all Security Documents and other documents, notices, certificates, instructions or communications received by the Collateral Trustee in its capacity as such.

SECTION 3.7 For Sole and Exclusive Benefit of Holders of Secured Debt Obligations. The Collateral Trustee will accept, hold, administer and enforce all Liens on the Collateral at any time transferred or delivered to it and all other interests, rights, powers and remedies at any time granted to or enforceable by the Collateral Trustee and all other property of the Trust Estates solely and exclusively for the benefit of the current and future holders of current and future Secured Debt Obligations, and will distribute all proceeds received by it in realization thereon or from enforcement thereof solely and exclusively pursuant to the provisions of Section 3.4.

SECTION 3.8 Additional Secured Debt.

(a) The Collateral Trustee will, as collateral trustee hereunder, perform its undertakings set forth in Section 3.1(a) with respect to each holder of Secured Debt Obligations of a Series of Secured Lien Debt that is issued or incurred after the date hereof (including any refinancing or replacement of a Series of Secured Lien Debt) that:

(1) holds Secured Debt Obligations that are identified as Junior Lien Debt or Parity Lien Debt in accordance with the procedures set forth in Section 3.8(b); and

F-27

(2) signs, through its designated Secured Debt Representative identified pursuant to Section 3.8(b), a Collateral Trust Joinder and delivers the same to the Collateral Trustee and each other Secured Debt Representative at the time of incurrence of such Series of Secured Lien Debt.

(b) EFH and EFIH will be permitted to designate as an additional holder of Secured Debt Obligations hereunder each Person who is, or who becomes, the registered holder of Junior Lien Debt or the registered holder of Parity Lien Debt incurred by EFH or EFIH after the date of this Agreement in accordance with the terms of all applicable Secured Debt Documents. The Company may only effect such designation by delivering to the Collateral Trustee and each Secured Debt Representative an Additional Secured Debt Designation stating that:

(1) EFH or EFIH intends to incur additional Secured Debt (“Additional Secured Debt”) which will either be (i) Parity Lien Debt permitted by each applicable Secured Debt Document to be secured by a Parity Lien Equally and Ratably with all previously existing and future Parity Lien Debt or (ii) Junior Lien Debt permitted by each applicable Secured Debt Document to be secured with a Junior Lien Equally and Ratably with all previously existing and future Junior Lien Debt;

(2) specifying the name and address of the Secured Debt Representative for such series of Additional Secured Debt for purposes of Section 7.7; and

(3) EFH or EFIH, as applicable, has duly authorized, executed (if applicable) and recorded (or caused to be recorded) in each appropriate governmental office all relevant filings and recordations to ensure that the Additional Secured Debt is secured by the Collateral in accordance with the Security Documents.

Although EFIH shall be required to deliver a copy of each Additional Secured Debt Designation and each Collateral Trust Joinder to each then existing Secured Debt Representative, the failure to so deliver a copy of the Additional Secured Debt Designation and/or Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the status of such debt as Additional Secured Debt if the other requirements of this Section 3.8 are complied with. Notwithstanding the foregoing, nothing in this Agreement will be construed to allow EFH or EFIH to incur additional Indebtedness unless otherwise permitted by the terms of all applicable Secured Debt Documents.

The Security Documents creating or evidencing the Parity Liens and the Junior Liens and Guarantees for the Parity Lien Obligations and the Junior Lien Obligations shall be in all material respects the same forms of documents other than with respect to the first lien and the second lien nature of the Obligations thereunder.

and, in each case, upon request of EFIH, at EFIH’s expense, the Collateral Trustee will execute (with such acknowledgements and/or notarizations as are required) any such documents as provided by EFIH and deliver evidence of such release to EFIH in the form provided by EFIH; provided, however, to the extent EFIH requests the Collateral Trustee to deliver evidence of the release of the Collateral in accordance with this Section 4.1(a), EFIH will deliver to the Collateral Trustee an Officer’s Certificate to the effect that no release of Collateral pursuant to this Section 4.1(a) violated the terms of any Secured Debt Documents.

(b) Other than with respect to any release pursuant to clause (2), (3), (4), (5) or (9) of Section 4.1(a) hereof, the Collateral Trustee agrees for the benefit of EFIH that if the Collateral Trustee at any time receives:

(1) an Officer’s Certificate stating that (A) the signing officer has read Article 4 of this Agreement and understands the provisions and the definitions relating hereto, (B) such officer has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not the conditions precedent in this Agreement and all other Secured Debt Documents, if any, relating to the release of the Collateral have been complied with and (C) in the opinion of such officer, such conditions precedent, if any, have been complied with; and

(2) at any time when a Secured Debt Default under a Series of Secured Lien Debt that constitutes Junior Lien Debt has occurred and is continuing, promptly after the receipt by it of any Act of Required Debtholders pursuant to Section 4.1(a)(5), the Collateral Trustee will deliver a copy of such Act of Required Debtholders to each Secured Debt Representative.

ARTICLE 5. IMMUNITIES OF THE COLLATERAL TRUSTEE

SECTION 5.1 No Implied Duty. The Collateral Trustee will not have any fiduciary duties nor will it have responsibilities or obligations other than those expressly

F-31

assumed by it in this Agreement and the other Security Documents to which it is a party. The Collateral Trustee will not be required to take any action that is contrary to applicable law or any provision of this Agreement or the other Security Documents to which it is a party.

SECTION 5.2 Appointment of Agents and Advisors. The Collateral Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents, attorneys, accountants, appraisers or other experts or advisors selected by it in good faith as it may reasonably require and will not be responsible for any misconduct or negligence on the part of any of them.

SECTION 5.3 Other Agreements. The Collateral Trustee has accepted and is bound by the Security Documents executed by the Collateral Trustee as of the date of this Agreement and, as directed by an Act of Required Debtholders, the Collateral Trustee shall execute additional Security Documents delivered to it after the date of this Agreement; provided, however, that such additional Security Documents do not adversely affect the rights, privileges, benefits and immunities of the Collateral Trustee. The Collateral Trustee will not otherwise be bound by, or be held obligated by, the provisions of any credit agreement, indenture or other agreement governing Secured Debt (other than this Agreement and the other Security Documents to which it is a party).

SECTION 5.4 Solicitation of Instructions.

(a) The Collateral Trustee may at any time solicit written confirmatory instructions, in the form of an Act of Required Debtholders, an Officer’s Certificate or an order of a court of competent jurisdiction, as to any action that it may be requested or required to take, or that it may propose to take, in the performance of any of its obligations under this Agreement or the other Security Documents.

(b) No written direction given to the Collateral Trustee by an Act of Required Debtholders, that in the reasonable judgment of the Collateral Trustee imposes, purports to impose or might reasonably be expected to impose upon the Collateral Trustee any obligation or liability not set forth in or arising under this Agreement and the other Security Documents will be binding upon the Collateral Trustee unless the Collateral Trustee elects, at its sole option, to accept such direction.

SECTION 5.5 Limitation of Liability. The Collateral Trustee will not be responsible or liable for any action taken or omitted to be taken by it hereunder or under any other Security Document, except for its own gross negligence, bad faith or willful misconduct as determined by a court of competent jurisdiction.

SECTION 5.6 Documents in Satisfactory Form. The Collateral Trustee will be entitled to require that all agreements, certificates, opinions, instruments and other documents at any time submitted to it, including those expressly provided for in this Agreement, be delivered to it in a form and with substantive provisions reasonably satisfactory to it.

SECTION 5.7 Entitled to Rely. The Collateral Trustee may seek and rely upon, and shall be fully protected in relying upon, any judicial order or judgment, upon any advice, opinion or statement of legal counsel, independent consultants and other experts selected

F-32

by it in good faith and upon any certification, instruction, notice or other writing delivered to it by EFIH in compliance with the provisions of this Agreement or delivered to it by any Secured Debt Representative as to the holders of Secured Debt Obligations for whom it acts, without being required to determine the authenticity thereof or the correctness of any fact stated therein or the propriety or validity of service thereof. The Collateral Trustee may act in reliance upon any instrument comporting with the provisions of this Agreement or any signature reasonably believed by it to be genuine and may assume that any Person purporting to give notice or receipt or advice or make any statement or execute any document in connection with the provisions hereof or the other Security Documents has been duly authorized to do so. To the extent an Officer’s Certificate or opinion of counsel is required or permitted under this Agreement to be delivered to the Collateral Trustee in respect of any matter, the Collateral Trustee may rely conclusively on an Officer’s Certificate or opinion of counsel as to such matter and such Officer’s Certificate or opinion of counsel shall be full warranty and protection to the Collateral Trustee for any action taken, suffered or omitted by it under the provisions of this Agreement and the other Security Documents.

SECTION 5.8 Secured Debt Default. The Collateral Trustee will not be required to inquire as to the occurrence or absence of any Secured Debt Default and will not be affected by or required to act upon any notice or knowledge as to the occurrence of any Secured Debt Default unless and until it is directed by an Act of Required Debtholders.

As to any matter not expressly provided for by this Agreement or the other Security Documents, the Collateral Trustee will act or refrain from acting as directed by an Act of Required Debtholders and will be fully protected if it does so, and any action taken, suffered or omitted pursuant hereto or thereto shall be binding on the holders of Secured Debt Obligations.

SECTION 5.10 Security or Indemnity in Favor of the Collateral Trustee. The Collateral Trustee will not be required to advance or expend any funds or otherwise incur any financial liability in the performance of its duties or the exercise of its powers or rights hereunder unless it has been provided with security or indemnity reasonably satisfactory to it against any and all liability or expense which may be incurred by it by reason of taking or continuing to take such action.

SECTION 5.11 Rights of the Collateral Trustee. In the event there is any bona fide, good faith disagreement between the other parties to this Agreement or any of the other Security Documents resulting in adverse claims being made in connection with Collateral held by the Collateral Trustee and the terms of this Agreement or any of the other Security Documents do not unambiguously mandate the action the Collateral Trustee is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Trustee is in doubt as to what action it is required to take or not to take hereunder or under the other Security Documents, it will be entitled to refrain from taking any action (and will incur no liability for doing so) until directed otherwise in writing by a request signed jointly by the parties hereto entitled to give such direction or by order of a court of competent jurisdiction.

F-33

SECTION 5.12 Limitations on Duty of Collateral Trustee in Respect of Collateral.

(a) Beyond the exercise of reasonable care in the custody of Collateral in its possession, the Collateral Trustee will have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto and the Collateral Trustee will not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Liens on the Collateral. The Collateral Trustee will be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and the Collateral Trustee will not be liable or responsible for any loss or diminution in the value of any of the Collateral by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Collateral Trustee in good faith.

(b) The Collateral Trustee will not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence, bad faith or willful misconduct on the part of the Collateral Trustee, for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title of EFIH or any Successor Company to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Collateral Trustee hereby disclaims any representation or warranty to the present and future holders of the Secured Debt Obligations concerning the perfection of the Liens granted hereunder or in the value of any of the Collateral.

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

SECTION 5.13 Assumption of Rights, Not Assumption of Duties. Notwithstanding anything to the contrary contained herein:

(1) each of the parties thereto will remain liable under each of the Security Documents (other than this Agreement) to the extent set forth therein to perform all of their respective duties and obligations thereunder to the same extent as if this Agreement had not been executed;

(2) the exercise by the Collateral Trustee of any of its rights, remedies or powers hereunder will not release such parties from any of their respective duties or obligations under the other Security Documents; and

F-34

(3) the Collateral Trustee will not be obligated to perform any of the obligations or duties of any of the parties thereunder other than the Collateral Trustee.

SECTION 5.14 No Liability for Clean Up of Hazardous Materials. In the event that the Collateral Trustee is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Collateral Trustee’s sole discretion may cause the Collateral Trustee to be considered an “owner or operator” under any environmental laws or otherwise cause the Collateral Trustee to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Collateral Trustee reserves the right, instead of taking such action, either to resign as Collateral Trustee or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Collateral Trustee will not be liable to any Person for any environmental liability or any environmental claims or contribution actions under any federal, state or local law, rule or regulation by reason of the Collateral Trustee’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or release or threatened discharge or release of any hazardous materials into the environment.

Within one year after a successor Collateral Trustee appointed by EFIH takes office, the holders of Secured Debt may, by an Act of Required Debtholders appoint a successor Collateral Trustee to replace the successor Collateral Trustee appoint by EFIH. If no successor Collateral Trustee has been so appointed and accepted such appointment within 45 days after the predecessor Collateral Trustee gave notice of resignation or was removed, the retiring Collateral Trustee may (at the expense of EFIH), at its option, appoint a successor Collateral Trustee, or petition a court of competent jurisdiction for appointment of a successor Collateral Trustee, which must be a bank or trust company:

(1) authorized to exercise corporate trust powers;

(2) having a combined capital and surplus of at least $100,000,000; and

F-35

(3) maintaining an office in any state of the United States.

(b) The Collateral Trustee will fulfill its obligations hereunder until a successor Collateral Trustee meeting the requirements of this Section 6.2 has accepted its appointment as Collateral Trustee and the provisions of Section 6.3 have been satisfied.

SECTION 6.3 Succession. When the Person so appointed as successor Collateral Trustee pursuant Section 6.2 accepts such appointment:

(1) such Person will succeed to and become vested with all the rights, powers, privileges and duties of the predecessor Collateral Trustee, and the predecessor Collateral Trustee will be discharged from its duties and obligations hereunder; and

(2) the predecessor Collateral Trustee will (at the expense of EFIH) promptly transfer all Liens and collateral security and other property of the Trust Estates within its possession or control to the possession or control of the successor Collateral Trustee and will execute instruments and assignments as may be necessary or reasonably requested by the successor Collateral Trustee to transfer to the successor Collateral Trustee all Liens, interests, rights, powers and remedies of the predecessor Collateral Trustee in respect of the Security Documents or the Trust Estates.

Thereafter the predecessor Collateral Trustee will remain entitled to enforce the immunities granted to it in Article 5 and the provisions of Sections 7.10 and 7.11.

SECTION 6.4 Merger, Conversion or Consolidation of Collateral Trustee. Any Person into which the Collateral Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Collateral Trustee shall be a party, or any Person succeeding to the business of the Collateral Trustee shall be the successor of the Collateral Trustee pursuant to Section 6.3, provided that (i) without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto, except where an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding, such Person satisfies the eligibility requirements specified in clauses (1) through (3) of Section 6.2 and (ii) prior to any such merger, conversion or consolidation, the Collateral Trustee shall have notified EFIH, each Parity Lien Representative and each Junior Lien Representative thereof in writing.

ARTICLE 7. MISCELLANEOUS PROVISIONS

SECTION 7.1 Amendment.

(a) No amendment or supplement to the provisions of this Agreement or any other Security Document will be effective without the approval of the Collateral Trustee acting as directed by an Act of Required Debtholders, except that:

(1) any amendment or supplement that has the effect solely of (i) adding or maintaining Collateral, securing additional Secured Debt that was otherwise permitted by the terms of the Secured Debt Documents to be secured by the Collateral or

F-36

preserving, perfecting or establishing the priority of the Liens thereon or the rights of the Collateral Trustee therein, (ii) curing any ambiguity, defect or inconsistency; (iii) providing for the assumption of EFIH’s obligations under any Security Document in the case of a merger or consolidation or sale of all or substantially all of EFIH’s assets; or (iv) making any change that would provide any additional rights or benefits to the holders of Secured Debt Obligations, the Secured Debt Representatives or the Collateral Trustee or that does not adversely affect the legal rights under any Secured Debt Document of any holder of Secured Debt Obligations, the Secured Debt Representatives or the Collateral Trustee, will, in each case, become effective when executed and delivered by EFIH and the Collateral Trustee;

(2) no amendment or supplement that reduces, impairs or adversely affects the right of any holder of Secured Debt Obligations:

(A) to vote its outstanding Secured Debt as to any matter requiring (i) an Act of Required Debtholders or (ii) direction by the Required Parity Lien Debtholders or the Required Junior Lien Debtholders, (or amends the provisions of this clause (2) or the definition of “Act of Required Debtholders,” “Required Parity Lien Debtholders” or “Required Junior Lien Debtholders”),

(B) to share, in the order of application described in Section 3.4, in the proceeds of enforcement of or realization on any Collateral that has not been released in accordance with the provisions described in Section 4.1, or

(C) to require that Liens securing Secured Debt Obligations be released only as set forth in the provisions described in Section 4.1,

will become effective without the consent of the requisite percentage or number of holders of each Series of Secured Lien Debt so affected under the applicable Secured Debt Documents; and

(3) no amendment or supplement that imposes any obligation upon the Collateral Trustee or any Secured Debt Representative or adversely affects the rights of the Collateral Trustee, as determined by the Collateral Trustee in its sole discretion, or any Secured Debt Representative, respectively, in its individual capacity as such will become effective without the consent of the Collateral Trustee or such Secured Debt Representative, respectively.

(b) Notwithstanding Section 7.1(a) but subject to Sections 7.1(a)(2) and 7.1(a)(3):

(1) any Security Document that secures Junior Lien Obligations (but not Parity Lien Obligations) may be amended or supplemented with the approval of the Collateral Trustee acting as directed in writing by the Required Junior Lien Debtholders, unless such amendment or supplement would not be permitted under the terms of this Agreement or the other Parity Lien Documents; and

F-37

(2) any amendment or waiver of, or any consent under, any provision of this Agreement or any other Security Document that secures Parity Lien Obligations (except any such amendment, waiver or consent that releases Collateral with respect to which any consent of holders of Junior Lien Debt is required pursuant to this Agreement, which will be governed by the provision in Section 7.1(a)) will apply automatically to any comparable provision of any comparable Junior Lien Document without the consent of or notice to any holder of Junior Lien Obligations and without any action by EFH, EFIH, any holder of Notes or other Junior Lien Obligations.

(c) The Collateral Trustee will not enter into any amendment or supplement unless it has received an Officer’s Certificate to the effect that such amendment or supplement will not result in a breach of any provision or covenant contained in any of the Secured Debt Documents. Prior to executing any amendment or supplement pursuant to this Section 7.1, the Collateral Trustee will be entitled to receive an opinion of counsel of EFIH (which may be provided by internal counsel to EFIH) to the effect that the execution of such document is authorized or permitted hereunder, that such document is the legal, valid and binding obligation of EFIH, enforceable against it in accordance with its terms, subject to customary exceptions, and with respect to amendments adding Collateral, an opinion of counsel of EFIH (which may be provided by internal counsel to EFIH) addressing customary perfection, and if such additional Collateral consists of equity interests of any Person, priority matters with respect to such additional Collateral (subject to customary qualifications and assumptions).

(d) The holders of Junior Lien Obligations and the Junior Lien Representatives agree that each Security Document that secures Junior Lien Obligations (but not also securing Parity Lien Obligations) will include language substantially to the effect of the following:

“Notwithstanding anything herein to the contrary, the lien and security interest granted to the Collateral Trustee pursuant to this Agreement and the exercise of any right or remedy by such Collateral Trustee hereunder are subject to the provisions of the Collateral Trust Agreement, dated as of November 16, 2009, among EFIH, The Bank of New York Mellon Trust Company, N.A., as Trustee under the EFH Indenture (as defined therein), The Bank of New York Mellon Trust Company, N.A., as Trustee under the EFIH Indenture (as defined therein) and The Bank of New York Mellon Trust Company, N.A., as Collateral Trustee (as amended, supplemented, amended and restated or otherwise modified and in effect from time to time, the “Collateral Trust Agreement”). In the event of any conflict between the terms of the Collateral Trust Agreement and this Agreement, the terms of the Collateral Trust Agreement will govern.”

; provided, however, that if the jurisdiction in which any such Junior Lien Document will be filed prohibits the inclusion of the language above or would prevent a document containing such language from being recorded, the Junior Lien Representatives and the Parity Lien Representatives agree, prior to such Junior Lien Document being entered into, to negotiate in good faith replacement language stating that the lien and security interest granted under such Junior Lien Document is subject to the provisions of this Agreement.

SECTION 7.2 Voting. In connection with any matter under this Agreement requiring a vote of holders of Secured Debt, each Series of Secured Lien Debt will

F-38

cast its votes in accordance with the Secured Debt Documents governing such Series of Secured Lien Debt. The amount of Secured Debt to be voted by a Series of Secured Lien Debt will equal (1) the aggregate outstanding principal amount of Secured Debt held by such Series of Secured Lien Debt (including outstanding letters of credit whether or not then available or drawn), plus (2) the aggregate unfunded commitments to extend credit which, when funded, would constitute Indebtedness of such Series of Secured Lien Debt. Following and in accordance with the outcome of the applicable vote under its Secured Debt Documents, the Secured Debt Representative of each Series of Secured Lien Debt will vote the total amount of Secured Debt under that Series of Secured Lien Debt as a block in respect of any vote under this Agreement.

SECTION 7.3 Further Assurances.

(a) EFIH will do or cause to be done all acts and things that may be required, or that the Collateral Trustee from time to time may reasonably request, to assure and confirm that the Collateral Trustee holds, for the benefit of the Secured Debt Representatives and holders of Secured Debt Obligations, duly created and enforceable and perfected Liens upon the Collateral (including any property or assets that are acquired or otherwise become Collateral after the date hereof), in each case as contemplated by, and with the Lien priority required under, the Secured Debt Documents.

(b) Upon the reasonable request of the Collateral Trustee or any Secured Debt Representative at any time and from time to time, EFIH, at its own expense, will promptly execute, acknowledge and deliver such additional security documents, instruments, certificates, notices and other documents, and take such other actions as may be reasonably required, or that the Collateral Trustee may reasonably request, to create, perfect, protect, assure or enforce the Liens and benefits intended to be conferred thereby, in each case as contemplated by the Secured Debt Documents for the benefit of holders of Secured Debt Obligations.

(c) Upon the request of the Collateral Trustee, EFIH will permit the Collateral Trustee or any of its agents or representatives, at reasonable times and intervals upon reasonable prior notice during regular business hours, to visit its offices and sites and inspect any of the Collateral and to discuss matters relating to the Collateral with its officers at EFIH’s expense. EFIH shall, at any reasonable time and from time to time upon reasonable prior notice during regular business hours, permit the Collateral Trustee or any of its agents or representatives to examine and make copies of and abstracts from the records and books of account of EFIH and its Subsidiaries, all at EFIH’s expense.

SECTION 7.4 Perfection of Junior Trust Estate. Solely for purposes of perfecting the Liens of the Collateral Trustee in its capacity as agent of the holders of Junior Lien Obligations and the Junior Lien Representatives in any portion of the Junior Trust Estate in the possession or control of the Collateral Trustee (or its agents or bailees) as part of the Senior Trust Estate including, without limitation, any instruments, goods, negotiable documents, tangible chattel paper, electronic chattel paper, certificated securities, money, deposit accounts and securities accounts, the Collateral Trustee, the holders of Parity Lien Obligations and the Parity Lien Representatives hereby acknowledge that the Collateral Trustee also holds such property as agent for the benefit of the Collateral Trustee for the benefit of the holders of Junior Lien Obligations and the Junior Lien Representatives.

F-39

SECTION 7.5 Successors and Assigns.

(a) Except as provided in Section 5.2, the Collateral Trustee may not, in its capacity as such, delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of the Collateral Trustee hereunder will inure to the sole and exclusive benefit of, and be enforceable by, each Secured Debt Representative and each present and future holder of Secured Debt Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

(b) The Company may not delegate any of its duties or assign any of its rights hereunder, and any attempted delegation or assignment of any such duties or rights will be null and void. All obligations of EFIH will inure to the sole and exclusive benefit of, and be enforceable by, the Collateral Trustee, each Secured Debt Representative and each present and future holder of Secured Debt Obligations, each of whom will be entitled to enforce this Agreement as a third-party beneficiary hereof, and all of their respective successors and assigns.

SECTION 7.6 Delay and Waiver. No failure to exercise, no course of dealing with respect to the exercise of, and no delay in exercising, any right, power or remedy arising under this Agreement or any of the other Security Documents will impair any such right, power or remedy or operate as a waiver thereof. No single or partial exercise of any such right, power or remedy will preclude any other or future exercise thereof or the exercise of any other right, power or remedy. The remedies herein are cumulative and are not exclusive of any remedies provided by law.

SECTION 7.10 Compensation; Expenses. EFIH agrees to pay, promptly upon demand:

(1) such compensation to the Collateral Trustee and its agents as EFIH and the Collateral Trustee may agree in writing from time to time;

(2) all reasonable costs and expenses incurred by the Collateral Trustee and its agents in the preparation, execution, delivery, filing, recordation, administration or enforcement of this Agreement (including this Section 7.10) or any other Security Document or any consent, amendment, waiver or other modification relating hereto or thereto;

(3) all reasonable fees, expenses and disbursements of legal counsel and any auditors, accountants, consultants or appraisers or other professional advisors and agents engaged by the Collateral Trustee incurred in connection with the negotiation, preparation, closing, administration, performance or enforcement of this Agreement and the other Security Documents or any consent, amendment, waiver or other modification relating hereto or thereto and any other document or matter requested by EFIH;

(b) All amounts due under this Section 7.11 will be payable upon demand.

(c) To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in Section 7.11(a) may be unenforceable in whole or in part because they violate any law or public policy, EFIH will contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them.

(d) EFIH will not assert any claim against any Indemnitee, on any theory of liability, for any lost profits or special, indirect or consequential damages or (to the fullest extent a claim for punitive damages may lawfully be waived) any punitive damages arising out of, in connection with, or as a result of, this Agreement or any other Secured Debt Document or any agreement or instrument or transaction contemplated hereby or relating in any respect to any Indemnified Liability, and EFIH hereby waives, releases and agrees not to xxx upon any claim for any such lost profits or special, indirect, consequential or (to the fullest extent lawful) punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

SECTION 7.12 Severability.

SECTION 7.14 Obligations Secured. All obligations of EFIH set forth in or arising under this Agreement will be Secured Debt Obligations and are secured by all Liens granted by the Security Documents.

SECTION 7.15 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

SECTION 7.16 Consent to Jurisdiction. All judicial proceedings brought against any party hereto arising out of or relating to this Agreement or any of the other Security Documents may be brought in any state or federal court of competent jurisdiction in the State, County and City of New York. By executing and delivering this Agreement, EFIH, for itself and in connection with its properties, irrevocably:

(1) accepts generally and unconditionally the nonexclusive jurisdiction and venue of such courts;

(2) waives any defense of forum non conveniens;

(3) agrees that service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to such party at its address provided in accordance with Section 7.7;

(4) agrees that service as provided in clause (3) above is sufficient to confer personal jurisdiction over such party in any such proceeding in any such court and otherwise constitutes effective and binding service in every respect; and

(5) agrees that each party hereto retains the right to serve process in any other manner permitted by law or to bring proceedings against any party in the courts of any other jurisdiction.

SECTION 7.17 Waiver of Jury Trial. Each party to this Agreement waives its rights to a jury trial of any claim or cause of action based upon or arising under this Agreement or any of the other Security Documents or any dealings between them relating to the subject matter of this Agreement or the intents and purposes of the other Security Documents. The scope of this waiver is intended to be all-encompassing of any and all disputes that may be

F-44

filed in any court and that relate to the subject matter of this Agreement and the other Security Documents, including contract claims, tort claims, breach of duty claims and all other common law and statutory claims. Each party to this Agreement acknowledges that this waiver is a material inducement to enter into a business relationship, that each party hereto has already relied on this waiver in entering into this Agreement, and that each party hereto will continue to rely on this waiver in its related future dealings. Each party hereto further warrants and represents that it has reviewed this waiver with its legal counsel and that it knowingly and voluntarily waives its jury trial rights following consultation with legal counsel. This waiver is irrevocable, meaning that it may not be modified either orally or in writing (other than by a mutual written waiver specifically referring to this Section 7.17 and executed by each of the parties hereto), and this waiver will apply to any subsequent amendments, renewals, supplements or modifications of or to this Agreement or any of the other Security Documents or to any other documents or agreements relating thereto. In the event of litigation, this Agreement may be filed as a written consent to a trial by the court.

SECTION 7.18 Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile or electronic transmission), each of which when so executed and delivered will be deemed an original, but all such counterparts together will constitute but one and the same instrument.

SECTION 7.19 Effectiveness. This Agreement will become effective upon the execution of a counterpart hereof by each of the parties hereto on the date hereof and receipt by each party of written notification of such execution and written or telephonic authorization of delivery thereof.

SECTION 7.20 Successor Company. EFIH will cause each Person that becomes a Successor Company or is required by any Secured Debt Document to become a party to this Agreement to become a party to this Agreement, for all purposes of this Agreement, by causing such Person to execute and deliver to the Collateral Trustee a Collateral Trust Joinder, whereupon such Person will be bound by the terms hereof to the same extent as if it had executed and delivered this Agreement as of the date hereof. EFIH shall promptly provide each Secured Debt Representative with a copy of each Collateral Trust Joinder executed and delivered pursuant to this Section 7.20; provided, however, that the failure to so deliver a copy of the Collateral Trust Joinder to any then existing Secured Debt Representative shall not affect the inclusion of such Person as a party hereto if the other requirements of this Section 7.20 are complied with.

SECTION 7.21 Continuing Nature of this Agreement. This Agreement, including the subordination provisions hereof, will be reinstated if at any time any payment or distribution in respect of any of the Parity Lien Obligations is rescinded or must otherwise be returned in an Insolvency or Liquidation Proceeding or otherwise by any holder of Parity Lien Obligations or Parity Lien Representative or any representative of any such party (whether by demand, settlement, litigation or otherwise). In the event that all or any part of a payment or distribution made with respect to the Parity Lien Obligations is recovered from any holder of Parity Lien Obligations or any Parity Lien Representative in an Insolvency or Liquidation Proceeding or otherwise, such payment or distribution received by any holder of Junior Lien Obligations or Junior Lien Representative with respect to the Junior Lien Obligations from the

F-45

proceeds of any Collateral at any time after the date of the payment or distribution that is so recovered, whether pursuant to a right of subrogation or otherwise, that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, will forthwith deliver the same to the Collateral Trustee, for the account of the holders of the Parity Lien Obligations and other Obligations secured by a Permitted Prior Lien, to be applied in accordance with Section 3.4. Until so delivered, such proceeds will be held by that Junior Lien Representative or that holder of a Junior Lien Obligation, as the case may be, for the benefit of the holders of the Parity Lien Obligations and other Obligations secured by a Permitted Prior Lien.

SECTION 7.22 Insolvency. This Agreement will be applicable both before and after the commencement of any Insolvency or Liquidation Proceeding by or against EFIH. The relative rights, as provided for in this Agreement, will continue after the commencement of any such Insolvency or Liquidation Proceeding on the same basis as prior to the date of the commencement of any such case, as provided in this Agreement.

SECTION 7.23 Rights and Immunities of Secured Debt Representatives. The Secured Debt Representatives will be entitled to all of the rights, protections, immunities and indemnities set forth in the Indentures and any future Secured Debt Representative will be entitled to all of the rights, protections, immunities and indemnities set forth in the credit agreement, indenture or other agreement governing the applicable Secured Debt with respect to which such Person is acting or will act as representative, in each case as if specifically set forth herein. In no event will any Secured Debt Representative be liable for any act or omission on the part of EFIH or the Collateral Trustee hereunder.

SECTION 7.24 Patriot Act. The parties hereto acknowledge that in accordance with Section 326 of the USA Patriot Act the Collateral Trustee, like all financial institutions, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account with it. The parties to this Agreement agree that they will provide the Collateral Trustee with such information as it may reasonably request in order for the Collateral Trustee to satisfy the requirements of the USA Patriot Act.

SECTION 7.25 Force Majeure. In no event shall the Collateral Trustee be responsible or liable for any failure or delay in the performance of its obligations under this Agreement arising out of or caused by, directly or indirectly, forces beyond its reasonable control, including without limitation strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software or hardware) services.
