As of April 28, 2011, there were 1,672,312,118 shares of common stock, without par value, outstanding of Energy Future Holdings Corp. (substantially all of which were owned by Texas Energy Future Holdings Limited Partnership, Energy Future Holdings Corp.’s parent holding company, and none of which is publicly traded).

Energy Future Holdings Corp.’s (EFH Corp.) annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports are made available to the public, free of charge, on the EFH Corp. website at http://www.energyfutureholdings.com, as soon as reasonably practicable after they have been filed with or furnished to the Securities and Exchange Commission. The information on EFH Corp.'s website shall not be deemed a part of, or incorporated by reference into, this quarterly report on Form 10-Q. Readers should not rely on or assume the accuracy of any representation or warranty in any agreement that EFH Corp. has filed as an exhibit to this Form 10-Q because such representation or warranty may be subject to exceptions and qualifications contained in separate disclosure schedules, may represent the parties’ risk allocation in the particular transaction, may be qualified by materiality standards that differ from what may be viewed as material for securities law purposes or may no longer continue to be true as of any given date.

This Form 10-Q and other Securities and Exchange Commission filings of EFH Corp. and its subsidiaries occasionally make references to EFH Corp. (or “we,” “our,” “us” or “the company”), EFCH, EFIH, TCEH, TXU Energy, Luminant, Oncor Holdings or Oncor when describing actions, rights or obligations of their respective subsidiaries. These references reflect the fact that the subsidiaries are consolidated with, or otherwise reflected in, their respective parent company’s financial statements for financial reporting purposes. However, these references should not be interpreted to imply that the relevant parent company is actually undertaking the action or has the rights or obligations of the relevant subsidiary company or vice versa.

When the following terms and abbreviations appear in the text of this report, they have the meanings indicated below.

EFH Corp., a Texas corporation, is a Dallas-based holding company with operations consisting principally of our TCEH and Oncor subsidiaries. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas, including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities, and retail electricity sales. Oncor is a majority (approximately 80%) owned subsidiary engaged in regulated electricity transmission and distribution operations in Texas. As discussed in Note 3, Oncor (and its majority owner, Oncor Holdings) are not consolidated in EFH Corp.’s financial statements as a result of amended consolidation accounting standards related to variable interest entities (VIEs) effective January 1, 2010.

References in this report to “we,” “our,” “us” and “the company” are to EFH Corp. and/or its subsidiaries, TCEH and/or its subsidiaries, or Oncor and/or its subsidiary as apparent in the context. See “Glossary” for other defined terms.

Various “ring-fencing” measures have been taken to enhance the credit quality of Oncor. Such measures include, among other things: the sale of a 19.75% equity interest in Oncor to Texas Transmission in November 2008; maintenance of separate books and records for the Oncor Ring-Fenced Entities; Oncor’s board of directors being comprised of a majority of independent directors, and prohibitions on the Oncor Ring-Fenced Entities providing credit support to, or receiving credit support from, any member of the Texas Holdings Group. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of the Texas Holdings Group, and none of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or contractual obligations of any member of the Texas Holdings Group. Moreover, Oncor’s operations are conducted, and its cash flows managed, independently from the Texas Holdings Group.

We have two reportable segments: the Competitive Electric segment, which is comprised principally of TCEH, and the Regulated Delivery segment, which is comprised of Oncor Holdings and its subsidiaries. See Note 14 for further information concerning reportable business segments.

The condensed consolidated financial statements have been prepared in accordance with US GAAP and on the same basis as the audited financial statements included in the 2010 Form 10-K. Investments in unconsolidated subsidiaries, which are 50% or less owned and/or do not meet accounting standards criteria for consolidation, are accounted for under the equity method (see Notes 2 and 3). All adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations and financial position have been included therein. All intercompany items and transactions have been eliminated in consolidation. All acquisitions of outstanding debt for cash, including notes that had been issued in lieu of cash interest, are presented in the financing activities section of the statement of cash flows. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with US GAAP have been omitted pursuant to the rules and regulations of the SEC. Because the condensed consolidated interim financial statements do not include all of the information and footnotes required by US GAAP, they should be read in conjunction with the audited financial statements and related notes included in the 2010 Form 10-K. The results of operations for an interim period may not give a true indication of results for a full year. All dollar amounts in the financial statements and tables in the notes are stated in millions of US dollars unless otherwise indicated.

Preparation of financial statements requires estimates and assumptions about future events that affect the reporting of assets and liabilities as of the balance sheet dates and the reported amounts of revenue and expense, including fair value measurements. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information. No material adjustments, other than those disclosed elsewhere herein, were made to previous estimates or assumptions during the current year.

Investments in unconsolidated subsidiary totaled $5.588 billion and $5.544 billion as of March 31, 2011 and December 31, 2010, respectively, and consisted of Oncor Holdings (100% owned), which we account for under the equity method (see Note 3). Oncor Holdings owns approximately 80% of Oncor, which is engaged in regulated electricity transmission and distribution operations in Texas. Distribution revenues from TCEH represented 34% and 38% of total revenues for Oncor Holdings for the three months ended March 31, 2011 and 2010, respectively. Condensed statements of consolidated income of Oncor Holdings for the three months ended March 31, 2011 and 2010 are presented below:

Assets and liabilities of Oncor Holdings as of March 31, 2011 and December 31, 2010 are presented below:

A VIE is an entity with which we have a relationship or arrangement that indicates some level of control over the entity or results in economic risks to us. Accounting standards require consolidation of a VIE if we have (a) the power to direct the significant activities of the VIE and (b) the right or obligation to absorb profit and loss from the VIE (primary beneficiary). Our VIEs consist of equity investees. In determining the appropriateness of consolidation of a VIE, we evaluate its purpose, governance structure, decision making processes and risks that are passed on to its interest holders. We also examine the nature of any related party relationships among the interest holders of the VIE and the nature of any special rights granted to the interest holders of the VIE.

As discussed below, our balance sheet includes assets and liabilities of VIEs that meet the consolidation standards. Oncor Holdings, which holds an approximate 80% interest in Oncor, is not consolidated in EFH Corp.’s financial statements because the structural and operational “ring-fencing” measures discussed in Note 1 prevent us from having power to direct the significant activities of Oncor Holdings or Oncor. We account for our investment in Oncor Holdings under the equity method, as opposed to the cost method, because, while we do not have the power to direct Oncor’s significant activities, we do have the ability to exercise significant influence (as defined by US GAAP) over its activities. Our maximum exposure to loss from our variable interests in VIEs does not exceed our carrying value. See Note 2 for additional information about equity method investments including condensed income statement and balance sheet data for Oncor Holdings.

See discussion in Note 5 regarding the VIE related to our accounts receivable securitization program that is consolidated under the accounting standards.

We also consolidate Comanche Peak Nuclear Power Company LLC (CPNPC), which was formed by subsidiaries of TCEH and Mitsubishi Heavy Industries Ltd. (MHI) for the purpose of developing two new nuclear generation units at our existing Comanche Peak nuclear-fueled generation facility using MHI’s US-Advanced Pressurized Water Reactor technology and to obtain a combined operating license from the NRC. CPNPC is currently financed through capital contributions from the subsidiaries of TCEH and MHI that hold 88% and 12% of CPNPC’s equity interests, respectively (see Note 8).

The carrying amounts and classifications of the assets and liabilities related to our consolidated VIEs are as follows:

The assets of our consolidated VIEs can only be used to settle the obligations of the VIE, and the creditors of our consolidated VIEs do not have recourse to our general credit.

The following table provides the goodwill balances as of March 31, 2011 and December 31, 2010, all of which relate to our competitive business. There were no changes to the goodwill balances in the three months ended March 31, 2011. None of the goodwill is being deducted for tax purposes.

Identifiable intangible assets reported in the balance sheet are comprised of the following:

Amortization expense related to intangible assets (including income statement line item) consisted of:

Estimated Amortization of Intangible Assets — The estimated aggregate amortization expense of intangible assets for each of the next five fiscal years is as follows:

TXU Energy participates in EFH Corp.’s accounts receivable securitization program with financial institutions (the funding entities). Under the program, TXU Energy (originator) sells trade accounts receivable to TXU Receivables Company, which is an entity created for the special purpose of purchasing receivables from the originator and is a consolidated, wholly-owned, bankruptcy-remote, direct subsidiary of EFH Corp. TXU Receivables Company sells undivided interests in the purchased accounts receivable for cash to entities established for this purpose by the funding entities. In accordance with an amended transfers and servicing accounting standard effective January 1, 2010, the trade accounts receivable amounts under the program are reported as pledged balances, and the related funding amounts are reported as short-term borrowings. Prior to the effective date of the amended accounting standard, the activity was accounted for as a sale of accounts receivable in accordance with previous accounting standards, which resulted in the funding being recorded as a reduction of accounts receivable.

The maximum funding amount currently available under the accounts receivable securitization program is $350 million. Program funding increased from $96 million as of December 31, 2010 to $101 million as of March 31, 2011. Under the terms of the program, available funding was reduced by $37 million of customer deposits held by the originator because TCEH’s credit ratings were lower than Ba3/BB-.

All new trade receivables under the program generated by the originator are continuously purchased by TXU Receivables Company with the proceeds from collections of receivables previously purchased. Ongoing changes in the amount of funding under the program, through changes in the amount of undivided interests sold by TXU Receivables Company, reflect seasonal variations in the level of accounts receivable, changes in collection trends and other factors such as changes in sales prices and volumes. TXU Receivables Company has issued a subordinated note payable to the originator for the difference between the face amount of the uncollected accounts receivable purchased, less a discount, and cash paid to the originator that was funded by the sale of the undivided interests. The subordinated note issued by TXU Receivables Company is subordinated to the undivided interests of the funding entities in the purchased receivables. The balance of the subordinated note payable, which is eliminated in consolidation, totaled $414 million and $516 million as of March 31, 2011 and December 31, 2010, respectively.

The discount from face amount on the purchase of receivables from the originator principally funds program fees paid to the funding entities. The program fees consist primarily of interest costs on the underlying financing and are reported as interest expense and related charges. The discount also funds a servicing fee, which is reported as SG&A expense, paid by TXU Receivables Company to EFH Corporate Services Company (Service Co.), a direct wholly-owned subsidiary of EFH Corp., which provides recordkeeping services and is the collection agent for the program.

Prior to the January 1, 2010 adoption of the amended accounting standard, changes in funding under the program were reported as operating cash flows, and the amended accounting rule required that the amount of funding under the program as of the adoption date ($383 million) be reported as a use of operating cash flows and a source of financing cash flows. All changes in funding subsequent to adoption of the amended standard are reported as financing activities.

The program, which expires in October 2013, may be terminated upon the occurrence of a number of specified events, including if the delinquency ratio (delinquent for 31 days) for the sold receivables, the default ratio (delinquent for 91 days or deemed uncollectible), the dilution ratio (reductions for discounts, disputes and other allowances) or the days collection outstanding ratio exceed stated thresholds, and the funding entities do not waive such event of termination. The thresholds apply to the entire portfolio of sold receivables. In addition, the program may be terminated if TXU Receivables Company or Service Co. defaults in any payment with respect to debt in excess of $50,000 in the aggregate for such entities, or if TCEH, any affiliate of TCEH acting as collection agent other than Service Co., any parent guarantor of the originator or the originator shall default in any payment with respect to debt (other than hedging obligations) in excess of $200 million in the aggregate for such entities. As of March 31, 2011, there were no such events of termination.

Upon termination of the program, liquidity would be reduced as collections of sold receivables would be used by TXU Receivables Company to repurchase the undivided interests from the funding entities instead of purchasing new receivables. The level of cash flows would normalize in approximately 16 to 30 days.

Gross trade accounts receivable as of March 31, 2011 and December 31, 2010 included unbilled revenues of $262 million and $297 million, respectively.

Receivables from unconsolidated subsidiary are measured at historical cost and primarily consist of Oncor’s obligation under the EFH Corp. pension and OPEB plans. EFH Corp. reviews Oncor’s credit scores to assess the overall collectability of its affiliated receivables, which totaled $1.460 billion and $1.463 billion as of March 31, 2011 and December 31, 2010, respectively. There were no credit loss allowances as of March 31, 2011. See Note 13 for additional information about related party transactions.

As of March 31, 2011, outstanding short-term borrowings totaled $1.004 billion, which included $903 million under the TCEH Revolving Credit Facility at a weighted average interest rate of 3.75%, excluding certain customary fees, and $101 million under the accounts receivable securitization program discussed in Note 5.

As of December 31, 2010, outstanding short-term borrowings totaled $1.221 billion, which included $1.125 billion under the TCEH Revolving Credit Facility at a weighted average interest rate of 3.80%, excluding certain customary fees, and $96 million under the accounts receivable securitization program.

Credit facilities with cash borrowing and/or letter of credit availability as of March 31, 2011 are presented below. The facilities are all senior secured facilities of TCEH. See “April 2011 Amendment, Extension and Repayments of TCEH Senior Secured Facilities” below for discussion of amendments, extensions and repayments of the facilities in April 2011.

As of March 31, 2011 and December 31, 2010, long-term debt consisted of the following:

Debt Repayments — Repayments of long-term debt in the three months ended March 31, 2011 totaled $71 million and included $51 million of principal payments at scheduled maturity dates and $19 million in contractual payments under capitalized lease obligations.

April 2011 Amendment, Extension and Repayments of TCEH Senior Secured Facilities — Borrowings under these facilities totaled $22.031 billion as of March 31, 2011. In April 2011, (i) the Credit Agreement governing the TCEH Senior Secured Facilities was amended, (ii) the maturity dates of approximately 80% of the borrowings under the term loans (initial term loans and delayed draw term loans) and deposit letter of credit loans under the TCEH Senior Secured Facilities and approximately 70% of the commitments under the TCEH Revolving Credit Facility were extended, (iii) borrowings totaling $1.6 billion under the TCEH Senior Secured Facilities were repaid from proceeds of issuance of $1.750 billion principal amount of TCEH 11.5% Senior Secured Notes as discussed below and (iv) the amount of commitments under the TCEH Revolving Credit Facility was reduced by $646 million. TCEH paid transaction costs totaling approximately $850 million in connection with the amendment and extensions.

The amendment to the Credit Agreement included, among other things, amendments to certain covenants contained in the TCEH Senior Secured Facilities (including the financial maintenance covenant), as well as acknowledgement by the lenders that (i) the terms of the intercompany notes receivable (as described below) from EFH Corp. payable to TCEH complied with the TCEH Senior Secured Facilities, including the requirement that these loans be made on an “arm’s-length” basis, and (ii) no mandatory repayments were required to be made by TCEH relating to “excess cash flows,” as defined under covenants of the TCEH Senior Secured Facilities, for fiscal years 2008, 2009 and 2010.

As amended, the maximum ratios for the secured debt to Adjusted EBITDA financial maintenance covenant are 8.00 to 1.00 for test periods ending from March 31, 2011 through December 31, 2014, and decline over time to 5.50 to 1.00 for the test periods ending March 31, 2017 and thereafter. The previous maximum ratios were 6.75 to 1.00 for the test periods ending December 31, 2010 through September 30, 2011, declining over time to 5.75 to 1.00 for the test period ending March 31, 2014 and thereafter. In addition, (i) up to $1.5 billion principal amount of TCEH senior secured first lien notes (including the TCEH Senior Secured Notes discussed below), to the extent the proceeds are used to repay term loans and deposit letter of credit loans under the TCEH Senior Secured Facilities and (ii) all senior secured second lien debt will be excluded for the purposes of the secured debt to Adjusted EBITDA financial maintenance covenant.

The amendment contains certain provisions related to intercompany loans to EFH Corp. payable to TCEH on demand that arise from cash loaned for (i) debt principal and interest payments (the “P&I Note”) and (ii) other general corporate purposes of EFH Corp. (the “SG&A Note”). In addition to the acknowledgements described above, TCEH agreed in the Amendment:

Further, in connection with the amendment, in April 2011 the following actions were completed related to the intercompany loans:

Upon the effectiveness of the extension, TCEH paid an up-front extension fee of 350 basis points on extended term loans and extended deposit letter of credit loans.

Each of the extended loans described above includes a “springing maturity” provision pursuant to which (i) in the event that more than $500 million aggregate principal amount of the TCEH 10.25% Notes due in 2015 (other than notes held by EFH Corp. or its controlled affiliates as of March 31, 2011 to the extent held as of the determination date) or more than $150 million aggregate principal amount of the TCEH Toggle Notes due in 2016 (other than notes held by EFH Corp. or its controlled affiliates as of March 31, 2011 to the extent held as of the determination date), as applicable, remain outstanding as of 91 days prior to the maturity date of the applicable notes and (ii) TCEH’s total debt to Adjusted EBITDA ratio (as defined in the TCEH Senior Secured Facilities) is greater than 6.00 to 1.00 at the applicable determination date, then the maturity date of the extended loans will automatically change to 90 days prior to the maturity date of the applicable notes.

Under the terms of the TCEH Senior Secured Facilities, the commitments of the lenders to make loans to TCEH are several and not joint. Accordingly, if any lender fails to make loans to TCEH, TCEH’s available liquidity could be reduced by an amount up to the aggregate amount of such lender’s commitments under the TCEH Senior Secured Facilities.

The TCEH Senior Secured Facilities are unconditionally guaranteed jointly and severally on a senior secured basis by EFCH, and subject to certain exceptions, each existing and future direct or indirect wholly-owned US restricted subsidiary of TCEH. The TCEH Senior Secured Facilities, including the guarantees thereof, certain commodity hedging transactions and the interest rate swaps described under “TCEH Interest Rate Swap Transactions” below are secured on a first priority basis by (i) substantially all of the current and future assets of TCEH and TCEH’s subsidiaries who are guarantors of such facilities and (ii) pledges of the capital stock of TCEH and certain current and future direct or indirect subsidiaries of TCEH.

Amounts borrowed under the TCEH Revolving Facility may be reborrowed from time to time until October 2013 with respect to the $640 million of commitments not extended and until October 2016 with respect to the $1.414 billion of commitments that were extended; such amounts borrowed totaled $205 million and $452 million, respectively, as of April 19, 2011. The TCEH Commodity Collateral Posting Facility will mature in December 2012.

April 2011 Issuance of TCEH 11.5% Senior Secured Notes — In April 2011, TCEH and TCEH Finance issued $1.750 billion principal amount of 11.5% Senior Secured Notes due 2020, and used the net proceeds to:

The TCEH Senior Secured Notes mature in October 2020, with interest payable in cash quarterly in arrears on January 1, April 1, July 1 and October 1, beginning July 1, 2011, at a fixed rate of 11.5% per annum. The notes are unconditionally guaranteed on a joint and several basis by EFCH and each subsidiary of TCEH (collectively, the Guarantors). The notes are secured, on a first-priority basis, by security interests in all of the assets of TCEH, and the guarantees are secured on a first-priority basis by all of the assets and equity interests held by the Guarantors, in each case, to the extent such assets and equity interests secure obligations under the TCEH Senior Secured Facilities (the TCEH Collateral), subject to certain exceptions and permitted liens.

The TCEH Senior Secured Notes were issued in private placements and are not registered under the Securities Act. The notes are a senior obligation and rank equally in right of payment with all senior indebtedness of TCEH, are senior in right of payment to all existing or future unsecured and second-priority debt of TCEH to the extent of the value of the TCEH Collateral and are senior in right of payment to any future subordinated debt of TCEH. These notes are effectively subordinated to all secured obligations of TCEH that are secured by assets other than the TCEH Collateral, to the extent of the value of the assets securing such obligations.

The guarantees of the TCEH Senior Secured Notes by the Guarantors are effectively senior to any unsecured and second-priority debt of the Guarantors to the extent of the value of the TCEH Collateral. The guarantees are effectively subordinated to all debt of the Guarantors secured by assets that are not part of the TCEH Collateral, to the extent of the value of the collateral securing that debt.

The indenture for the TCEH Senior Secured Notes contains a number of covenants that, among other things, restrict, subject to certain exceptions, TCEH’s and its restricted subsidiaries’ ability to:

The indenture also contains customary events of default, including, among others, failure to pay principal or interest on the notes when due. If certain events of default occur under the indenture, the trustee or the holders of at least 30% of aggregate principal amount of all outstanding TCEH Senior Secured Notes may declare the principal amount on all such notes to be due and payable immediately.

Until April 1, 2014, TCEH may redeem, with the net cash proceeds of certain equity offerings, up to 35% of the aggregate principal amount of the TCEH Senior Secured Notes from time to time at a redemption price of 111.5% of the aggregate principal amount of the notes being redeemed, plus accrued interest. TCEH may redeem the notes at any time prior to April 1, 2016 at a price equal to 100% of their principal amount, plus accrued interest and the applicable premium as defined in the indenture. TCEH may also redeem the notes, in whole or in part, at any time on or after April 1, 2016, at specified redemption prices, plus accrued interest. Upon the occurrence of a change of control (as described in the indenture), TCEH must offer to repurchase the notes at 101% of their principal amount, plus accrued interest.

April 2011 EFIH Debt Exchanges — In private exchanges in April 2011, EFIH and EFIH Finance issued $406 million principal amount of 11% Senior Secured Second Lien Notes due 2021 in exchange for $428 million of EFH Corp. debt consisting of $163 million principal amount of EFH Corp. 10.875% Notes due 2017, $229 million principal amount of EFH Corp. Toggle Notes due 2017 and $36 million principal amount of EFH Corp. 5.55% Series P Senior Notes due 2014. EFIH intends to hold the acquired securities as an investment. The EFIH 11% Notes are secured on a second-priority basis by the EFIH Collateral described in the discussion of the EFH Corp. 10% Senior Secured Notes below.

TCEH 10.25% Senior Notes (including Series B) and 10.50/11.25% Senior Toggle Notes (collectively, the TCEH Senior Notes) — The TCEH 10.25% Notes mature in November 2015, with interest payable in cash semi-annually in arrears on May 1 and November 1 at a fixed rate of 10.25% per annum. The Toggle Notes mature in November 2016, with interest payable semi-annually in arrears on May 1 and November 1 at a fixed rate of 10.50% per annum for cash interest and at a fixed rate of 11.25% per annum for PIK Interest. For any interest period until November 2012, TCEH may elect to pay interest on the notes (i) entirely in cash; (ii) by increasing the principal amount of the notes or by issuing new TCEH Toggle Notes (PIK Interest); or (iii) 50% in cash and 50% in PIK Interest. Once TCEH makes a PIK election, the election is valid for each succeeding interest payment period until TCEH revokes the election.

These notes had a total principal amount as of March 31, 2011 of $4.571 billion (excluding $323 million principal amount held by EFH Corp. and EFIH) and are fully and unconditionally guaranteed on a joint and several unsecured basis by TCEH’s direct parent, EFCH (which owns 100% of TCEH and its subsidiary guarantors), and by each subsidiary that guarantees the TCEH Senior Secured Facilities.

TCEH 15% Senior Secured Second Lien Notes (including Series B) — These notes mature in April 2021, with interest payable in cash quarterly in arrears on January 1, April 1, July 1 and October 1 at a fixed rate of 15% per annum, and had a total principal amount of $1.571 billion as of March 31, 2011. The notes are unconditionally guaranteed on a joint and several basis by EFCH and, subject to certain exceptions, each subsidiary of TCEH that guarantees the TCEH Senior Secured Facilities (collectively, the Guarantors). The notes are secured, on a second-priority basis, by security interests in all of the assets of TCEH, and the guarantees (other than the guarantee of EFCH) are secured on a second-priority basis by all of the assets and equity interests of all of the Guarantors other than EFCH (collectively, the Subsidiary Guarantors), in each case, to the extent such assets and security interests secure obligations under the TCEH Senior Secured Facilities (the TCEH Collateral), subject to certain exceptions (including the elimination of the pledge of equity interests of any Subsidiary Guarantor to the extent that separate financial statements would be required to be filed with the SEC for such Subsidiary Guarantor under Rule 3-16 of Regulation S-X) and permitted liens. The guarantee from EFCH is not secured.

The TCEH Senior Secured Second Lien Notes were issued in private placements and have not been registered under the Securities Act. TCEH has agreed to use its commercially reasonable efforts to register with the SEC notes having substantially identical terms as the TCEH Senior Secured Second Lien Notes (except for provisions relating to transfer restrictions and payment of additional interest) as part of an offer to exchange freely tradable exchange notes for the TCEH Senior Secured Second Lien Notes unless such notes meet certain transferability conditions (as described in the related registration rights agreement). If the registration statement has not been filed and declared effective within 365 days after the original issue date (a Registration Default), the annual interest rate on the notes will increase by 25 basis points for the first 90-day period during which a Registration Default continues, and thereafter the annual interest rate on the notes will increase by 50 basis points for the remaining period during which the Registration Default continues. If the Registration Default is cured, the interest rate on the notes will revert to the original level.

EFH Corp. 10% Senior Secured Notes — These notes mature in January 2020, with interest payable in cash semi-annually in arrears on January 15 and July 15 at a fixed rate of 10% per annum, and had a total principal amount of $1.061 billion as of March 31, 2011. The notes are fully and unconditionally guaranteed on a joint and several basis by EFCH and EFIH. The guarantee from EFIH is secured by EFIH’s pledge of 100% of the membership interests and other investments it owns in Oncor Holdings (such membership interests and other investments, the EFIH Collateral). The guarantee from EFCH is not secured. EFIH’s guarantee of the EFH Corp. 10% Notes is secured by the EFIH Collateral on an equal and ratable basis with the EFIH Notes and EFIH’s guarantee of the EFH Corp. 9.75% Notes.

The EFH Corp. 10% Notes were issued in private placements with registration rights. In March 2011, EFH Corp. completed an offer to exchange notes registered under the Securities Act that have substantially identical terms (other than transfer restrictions) for the EFH Corp. 10% Notes.

EFH Corp. 10.875% Senior Notes and 11.25/12.00% Senior Toggle Notes (collectively, EFH Corp. Senior Notes) — These notes mature in November 2017, with interest payable in cash semi-annually in arrears on May 1 and November 1 at a fixed rate for the 10.875% Notes of 10.875% per annum and for the Toggle Notes a fixed rate of 11.250% per annum for cash interest and a fixed rate of 12.000% per annum for PIK Interest. For any interest period until November 1, 2012, EFH Corp. may elect to pay interest on the notes (i) entirely in cash; (ii) by increasing the principal amount of the notes or by issuing new EFH Corp. Toggle Notes (PIK Interest); or (iii) 50% in cash and 50% in PIK Interest. Once EFH Corp. makes a PIK election, the election is valid for each succeeding interest payment period until EFH Corp. revokes the election.

These notes had a total principal amount as of March 31, 2011 of $930 million (excluding $3.724 billion principal amount held by EFIH) and are fully and unconditionally guaranteed on a joint and several unsecured basis by EFCH and EFIH.

EFIH 10% Senior Secured Notes — These notes mature in December 2020, with interest payable in cash semi-annually in arrears on June 1 and December 1 at a fixed rate of 10% per annum, and had a total principal amount of $2.180 billion as of March 31, 2011. The EFIH 10% Notes are secured by the EFIH Collateral on an equal and ratable basis with the EFIH 9.75% Notes and EFIH’s guarantee of the EFH Corp. Senior Secured Notes.

As of March 31, 2011, TCEH has entered into interest rate swap transactions pursuant to which payment of the floating interest rates on an aggregate of $17.87 billion principal amount of senior secured term loans of TCEH were exchanged for interest payments at fixed rates of between 5.6% and 8.3% on debt maturing from 2012 to 2014. Swaps related to an aggregate $2.60 billion principal amount of debt expired or were terminated in the three months ended March 31, 2011, and swaps related to an aggregate $4.67 billion principal amount of debt (growing to $8.64 billion over time, primarily as existing swaps expire) were entered into in the three months ended March 31, 2011. Subsequent to the end of the quarter through April 27, 2011, TCEH entered into additional swaps related to an aggregate $781 million principal amount of debt (growing to $1.936 billion over time to October 2014, primarily as existing swaps expire).

As of March 31, 2011, TCEH has entered into interest rate basis swap transactions pursuant to which payments at floating interest rates of three-month LIBOR on an aggregate of $12.70 billion principal amount of senior secured term loans of TCEH were exchanged for floating interest rates of one-month LIBOR plus spreads ranging from 0.0625% to 0.1910%. In the three months ended March 31, 2011, interest rate basis swaps related to an aggregate $2.5 billion principal amount of TCEH senior secured term loans expired, and no additional basis swaps were entered into by TCEH.

The interest rate swap counterparties are proportionately secured by the same collateral package granted to the lenders under the TCEH Senior Secured Facilities. Changes in the fair value of such swaps are being reported in the income statement in interest expense and related charges, and such unrealized mark-to-market value changes totaled $142 million in net gains and $107 million in net losses in the three months ended March 31, 2011 and 2010, respectively. The cumulative unrealized mark-to-market net liability related to the swaps totaled $1.277 billion as of March 31, 2011, of which $94 million (pre-tax) was reported in accumulated other comprehensive income.

We have entered into contracts that contain guarantees to unaffiliated parties that could require performance or payment under certain conditions. Material guarantees are discussed below.

Disposed TXU Gas operations — In connection with the sale of TXU Gas in October 2004, EFH Corp. agreed to indemnify Atmos Energy Corporation (Atmos), until October 1, 2014, for up to $500 million for any liability related to assets retained by TXU Gas, including certain inactive gas plant sites not acquired by Atmos, and up to $1.4 billion for contingent liabilities associated with preclosing tax and employee related matters. The maximum aggregate amount under these indemnities that we may be required to pay is $1.9 billion. To date, we have not been required to make any payments to Atmos under any of these indemnity obligations, and no such payments are currently anticipated.

Residual value guarantees in operating leases — We are the lessee under various operating leases that guarantee the residual values of the leased assets. As of March 31, 2011, both the aggregate maximum amount of residual values guaranteed and the estimated residual recoveries totaled $13 million. These leased assets consist primarily of rail cars. The average life of the residual value guarantees under the lease portfolio is approximately 5 years.

See Note 6 above and Note 11 to Financial Statements in the 2010 Form 10-K for discussion of guarantees and security for certain of our indebtedness.

As of March 31, 2011, TCEH had outstanding letters of credit under its credit facilities totaling $887 million as follows:

In November 2010, an administrative appeal challenging the decision of the TCEQ to renew and amend Oak Grove Management Company LLC’s (Oak Grove) (a wholly-owned subsidiary of TCEH) Texas Pollutant Discharge Elimination System (TPDES) permit related to water discharges was filed by Robertson County: Our Land, Our Lives and Roy Henrichson in the Travis County, Texas District Court. Plaintiffs seek a reversal of the TCEQ’s order and a remand back to the TCEQ for further proceedings. In addition to this administrative appeal, in November 2010, two other petitions were filed in Travis County, Texas District Court by Sustainable Energy and Economic Development Coalition and Paul and Lisa Rolke, respectively, who were non-parties to the administrative hearing before the State Office of Administrative Hearings, challenging the TCEQ’s decision to renew and amend Oak Grove’s TPDES permit and asking the District Court to remand the matter to the TCEQ for further proceedings. Although we cannot predict the outcome of these proceedings, we believe that the renewal and amendment of the Oak Grove TPDES permit are protective of the environment and that the application for and the processing of Oak Grove’s TPDES permit renewal and amendment by the TCEQ were in accordance with applicable law. There can be no assurance that the outcome of these matters would not result in an adverse impact on our financial condition, results of operations or liquidity.

In September 2010, the Sierra Club filed a lawsuit in the US District Court for the Eastern District of Texas (Texarkana Division) against EFH Corp. and Luminant Generation Company LLC (a wholly-owned subsidiary of TCEH) for alleged violations of the Clean Air Act at Luminant’s Martin Lake generation facility. While we are unable to estimate any possible loss or predict the outcome of the litigation, we believe that the Sierra Club’s claims are without merit, and we intend to vigorously defend this litigation. In addition, in February 2010, the Sierra Club informed Luminant that it may sue Luminant, after the expiration of a 60-day waiting period, for allegedly violating federal Clean Air Act provisions in connection with Luminant’s Big Brown generation facility. Subsequently, in December 2010, Sierra Club informed Luminant that it may sue Luminant, after the expiration of a 60-day waiting period, for allegedly violating federal Clean Air Act provisions in connection with Luminant’s Monticello generation facility. We cannot predict whether the Sierra Club will actually file suit or the outcome of any resulting proceedings.

In June 2008, the EPA issued a request for information to TCEH under the EPA’s authority under Section 114 of the Clean Air Act. The stated purpose of the request is to obtain information necessary to determine compliance with the Clean Air Act, including New Source Review Standards and air permits issued by the TCEQ for the Big Brown, Monticello and Martin Lake generation facilities. Historically, as the EPA has pursued its New Source Review enforcement initiative, companies that have received a large and broad request under Section 114, such as the request received by TCEH, have in many instances subsequently received a notice of violation from the EPA, which has in some cases progressed to litigation or settlement. We are cooperating with the EPA and responding in good faith to the EPA’s request, but we are unable to predict the outcome of this matter.

In addition to the above, we are involved in various other legal and administrative proceedings in the normal course of business, the ultimate resolution of which, in the opinion of management, should not have a material effect on our financial condition, results of operations or liquidity.

The indentures governing the EFH Corp. Senior Notes and EFH Corp. Senior Secured Notes include covenants that, among other things and subject to certain exceptions, restrict our ability to pay dividends or make other distributions in respect of our common stock. Accordingly, essentially all of our net income is restricted from being used to make distributions on our common stock unless such distributions are expressly permitted under these indentures and/or on a pro forma basis, after giving effect to such distribution, EFH Corp.’s consolidated leverage ratio is equal to or less than 7.0 to 1.0. For purposes of this calculation, “consolidated leverage ratio” is defined as the ratio of consolidated total debt (as defined in the indenture) to Adjusted EBITDA, in each case, consolidated with its subsidiaries other than Oncor Holdings and its subsidiaries. EFH Corp.’s consolidated leverage ratio was 8.8 to 1.0 as of March 31, 2011.

In addition, the indentures governing the EFIH Notes generally restrict EFIH from making any cash distribution to EFH Corp. for the ultimate purpose of making a cash dividend on our common stock unless at the time, and after giving effect to such dividend, EFIH’s consolidated leverage ratio is equal to or less than 6.0 to 1.0. Under the indentures governing the EFIH Notes, the term “consolidated leverage ratio” is defined as the ratio of EFIH’s consolidated total debt (as defined in the indentures) to EFIH’s Adjusted EBITDA on a consolidated basis (including Oncor’s Adjusted EBITDA). EFIH’s consolidated leverage ratio was 5.4 to 1.0 as of March 31, 2011.

The TCEH Senior Secured Facilities generally restrict TCEH from making any cash distribution to any of its parent companies for the ultimate purpose of making a cash dividend on our common stock unless at the time, and after giving effect to such dividend, its consolidated total debt (as defined in the TCEH Senior Secured Facilities) to Adjusted EBITDA would be equal to or less than 6.5 to 1.0. As of March 31, 2011, that ratio was 8.1 to 1.0.

In addition, the TCEH Senior Secured Facilities and indentures governing the TCEH Senior Notes, TCEH Senior Secured Notes and TCEH Senior Secured Second Lien Notes generally restrict TCEH’s ability to make distributions or loans to any of its parent companies, EFCH and EFH Corp., unless such distributions or loans are expressly permitted under the TCEH Senior Secured Facilities and the indentures governing such notes. See discussion in Note 6 regarding amendments to the TCEH Senior Secured Facilities affecting intercompany loans from TCEH to EFH Corp.

In addition, under applicable law, we would be prohibited from paying any dividend to the extent that immediately following payment of such dividend, there would be no statutory surplus or we would be insolvent.

Distributions from Oncor — Oncor’s distributions to us totaled $16 million and $30 million in the three months ended March 31, 2011 and 2010, respectively. Until December 31, 2012, distributions paid by Oncor to its members are limited to an amount not to exceed Oncor’s net income determined in accordance with US GAAP, subject to certain defined adjustments. Such adjustments include deducting the $72 million ($46 million after-tax) one-time refund to customers in September 2008, net accretion of fair value adjustments resulting from purchase accounting and funds spent as part of the $100 million commitment for additional demand-side management or other energy efficiency initiatives of which $52 million ($34 million after tax) has been spent through March 31, 2011, and removing the effects of the $860 million goodwill impairment charge from fourth quarter 2008 net income available for distribution. As of March 31, 2011, $177 million was available for distribution to Oncor’s members under the cumulative net income restriction, of which approximately 80% relates to EFH Corp.’s ownership interest in Oncor.

Oncor’s distributions are further limited by an agreement with the PUCT that its regulatory capital structure, as determined by the PUCT, will be at or below the assumed debt-to-equity ratio established periodically by the PUCT for ratemaking purposes, which is currently set at 60% debt to 40% equity. As of March 31, 2011, the regulatory capitalization ratio was 59.4% debt and 40.6% equity. The PUCT has the authority to determine what types of debt and equity are included in a utility’s debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. The debt calculation excludes transition bonds issued by Oncor Electric Delivery Transition Bond Company. Equity is calculated as membership interests determined in accordance with US GAAP, excluding the effects of accounting for the Merger (which included recording the initial goodwill and fair value adjustments and the subsequent related impairments and amortization). As of March 31, 2011, $83 million was available for distribution under the capital structure restriction, of which approximately 80% relates to our ownership interest in Oncor.

As discussed in Note 3, EFH Corp. consolidates a joint venture formed for the purpose of developing two new nuclear generation units, which results in a noncontrolling interests component of equity. Net loss attributable to the noncontrolling interests was immaterial for the three months ended March 31, 2011 and 2010.

The following table presents the changes to equity during the three months ended March 31, 2011.

The following table presents the changes to equity during the three months ended March 31, 2010.

Accounting standards related to the determination of fair value define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use a “mid-market” valuation convention (the mid-point price between bid and ask prices) as a practical expedient to measure fair value for the majority of our assets and liabilities subject to fair value measurement on a recurring basis. We primarily use the market approach for recurring fair value measurements and use valuation techniques to maximize the use of observable inputs and minimize the use of unobservable inputs.

We categorize our assets and liabilities recorded at fair value based upon the following fair value hierarchy:

We utilize several different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those items that are measured on a recurring basis. These methods include, among others, the use of broker quotes and statistical relationships between different price curves.

In utilizing broker quotes, we attempt to obtain multiple quotes from brokers that are active in the commodity markets in which we participate (and require at least one quote from two brokers to determine a pricing input as observable); however, not all pricing inputs are quoted by brokers. The number of broker quotes received for certain pricing inputs varies depending on the depth of the trading market, each individual broker’s publication policy, recent trading volume trends and various other factors. In addition, for valuation of interest rate swaps, we use a combination of dealer provided market valuations (generally non-binding) and Bloomberg valuations based on month-end interest rate curves and standard rate swap valuation models.

Certain derivatives and financial instruments are valued utilizing option pricing models that take into consideration multiple inputs including commodity prices, volatility factors, discount rates and other inputs. Additionally, when there is not a sufficient amount of observable market data, valuation models are developed that incorporate proprietary views of market factors. Those valuation models are generally used in developing long-term forward price curves for certain commodities. We believe the development of such curves is consistent with industry practice; however, the fair value measurements resulting from such curves are classified as Level 3.

With respect to amounts presented in the following fair value hierarchy tables, the fair value measurement of an asset or liability (e.g., a contract) is required to fall in its entirety in one level, based on the lowest level input that is significant to the fair value measurement. Certain assets and liabilities would be classified in Level 2 instead of Level 3 of the hierarchy except for the effects of credit reserves and non-performance risk adjustments, respectively. Assessing the significance of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability being measured.

As of March 31, 2011, assets and liabilities measured at fair value on a recurring basis consisted of the following:

As of December 31, 2010, assets and liabilities measured at fair value on a recurring basis consisted of the following:

In conjunction with ERCOT’s transition to a nodal wholesale market structure effective December 2010, we have entered (and expect to increasingly enter) into certain derivative transactions that are valued at illiquid pricing locations (unobservable inputs), thus requiring classification as Level 3 assets or liabilities. As the nodal market matures and more transactions and pricing information becomes available for these pricing locations, we expect more of the valuation inputs to become observable.

Commodity contracts consist primarily of natural gas, electricity, fuel oil and coal derivative instruments entered into for hedging purposes and include physical contracts that have not been designated “normal” purchases or sales. See Note 11 for further discussion regarding the company’s use of derivative instruments.

Interest rate swaps include variable-to-fixed rate swap instruments that are economic hedges of interest on long-term debt as well as interest rate basis swaps designed to effectively reduce the hedged borrowing costs. See Note 6 for discussion of interest rate swaps.

Nuclear decommissioning trust assets represent securities held for the purpose of funding the future retirement and decommissioning of the nuclear generation units. These investments include equity, debt and other fixed-income securities consistent with investment rules established by the NRC and the PUCT.

There were no significant transfers between Level 1 and Level 2 of the fair value hierarchy for the three months ended March 31, 2011 or 2010. See the table below for discussion of transfers between Level 2 and Level 3.

The following table presents the changes in fair value of the Level 3 assets and liabilities (all related to commodity contracts) for the three months ended March 31, 2011 and 2010:

The carrying amounts and related estimated fair values of significant nonderivative financial instruments as of March 31, 2011 and December 31, 2010 were as follows:

See Notes 9 and 11 for discussion of accounting for financial instruments that are derivatives.

We enter into physical and financial derivative instruments, such as options, swaps, futures and forward contracts, primarily to manage commodity price risk and interest rate risk exposure. Our principal activities involving derivatives consist of a long-term commodity hedging program and the hedging of interest costs on our long-term debt. See Note 9 for a discussion of the fair value of all derivatives.

Long-Term Hedging Program — TCEH has a long-term hedging program designed to reduce exposure to changes in future electricity prices due to changes in the price of natural gas, thereby hedging future revenues from electricity sales and related cash flows. In ERCOT, the wholesale price of electricity is largely correlated to the price of natural gas. Under the program, TCEH has entered into market transactions involving natural gas-related financial instruments and has sold forward natural gas through 2014. These transactions are intended to hedge a majority of electricity price exposure related to expected baseload generation for this period. Changes in the fair value of the instruments under the long-term hedging program are reported in the income statement in net gain (loss) from commodity hedging and trading activities.

Interest Rate Swap Transactions — Interest rate swap agreements are used to reduce exposure to interest rate changes by converting floating-rate debt to fixed rates, thereby hedging future interest costs and related cash flows. Interest rate basis swaps are used to effectively reduce the hedged borrowing costs. Changes in the fair value of the swaps are recorded as unrealized gains and losses in interest expense and related charges. See Note 6 for additional information about interest rate swap agreements.

Other Commodity Hedging and Trading Activity — In addition to the long-term hedging program, TCEH enters into derivatives, including electricity, natural gas, fuel oil and coal instruments, generally for shorter-term hedging purposes. To a limited extent, TCEH also enters into derivative transactions for proprietary trading purposes, principally in natural gas and electricity markets.

Substantially all commodity and other derivative contractual assets and liabilities arise from mark-to-market accounting consistent with accounting standards related to derivative instruments and hedging activities. The following tables provide detail of commodity and other derivative contractual assets and liabilities (with the column totals representing the net positions of the contracts) as reported in the balance sheets as of March 31, 2011 and December 31, 2010:

As of March 31, 2011 and December 31, 2010, there were no derivative positions accounted for as cash flow or fair value hedges.

Margin deposits that contractually offset these derivative instruments are reported separately in the balance sheet and totaled $561 million and $479 million in net liabilities as of March 31, 2011 and December 31, 2010, respectively. Reported amounts as presented in the above table do not reflect netting of assets and liabilities with the same counterparties under existing netting arrangements. This presentation can result in significant volatility in derivative assets and liabilities because we may enter into offsetting positions with the same counterparties, resulting in both assets and liabilities, and the underlying commodity prices can change significantly from period to period.

The following table presents the pre-tax effect on net income of derivatives not under hedge accounting, including realized and unrealized effects:

The following table presents the pre-tax effect on net income and other comprehensive income (OCI) of derivative instruments previously accounted for as cash flow hedges:

There were no transactions designated as cash flow hedges during the three months ended March 31, 2011 and 2010.

Accumulated other comprehensive income related to cash flow hedges as of March 31, 2011 and December 31, 2010 totaled $62 million and $69 million in net losses (after-tax), respectively, substantially all of which relates to interest rate swaps. We expect that $15 million of net losses (after-tax) related to cash flow hedges included in accumulated other comprehensive income as of March 31, 2011 will be reclassified into net income during the next twelve months as the related hedged transactions affect net income.

Derivative Volumes — The following table presents the gross notional amounts of derivative volumes as of March 31, 2011 and December 31, 2010:

The agreements that govern our derivative instrument transactions may contain certain credit risk-related contingent features that could trigger liquidity requirements in the form of cash collateral, letters of credit or some other form of credit enhancement. Certain of those agreements require the posting of collateral if our credit rating is downgraded by one or more credit rating agency; however, due to our credit ratings being below investment grade, substantially all of such collateral posting requirements are already effective.

As of March 31, 2011 and December 31, 2010, the fair value of liabilities related to derivative instruments under agreements with credit risk-related contingent features that were not fully cash collateralized totaled $423 million and $408 million, respectively. The liquidity exposure associated with these liabilities was reduced by cash and letter of credit postings with the counterparties totaling $88 million and $65 million as of March 31, 2011 and December 31, 2010, respectively. If all the credit risk-related contingent features related to these derivatives had been triggered, including cross default provisions, as of March 31, 2011 and December 31, 2010, the remaining related liquidity requirement would have totaled $13 million and $18 million, respectively, after reduction for net accounts receivable and derivative assets under netting arrangements.

In addition, certain derivative agreements that are collateralized primarily with asset liens include indebtedness cross-default provisions that could result in the settlement of such contracts if there were a failure under other financing arrangements to meet payment terms or to comply with other covenants that could result in the acceleration of such indebtedness. As of March 31, 2011 and December 31, 2010, the fair value of derivative liabilities subject to such cross-default provisions, largely related to interest rate swaps, totaled $1.636 billion and $1.865 billion, respectively (before consideration of the amount of assets under the liens). No cash collateral or letters of credit were posted with these counterparties as of March 31, 2011 and December 31, 2010 to reduce the liquidity exposure. If all the credit risk-related contingent features related to these derivatives, including amounts related to cross-default provisions, had been triggered as of March 31, 2011 and December 31, 2010, the remaining related liquidity requirement would have totaled $519 million and $674 million, respectively, after reduction for derivative assets under netting arrangements (before consideration of the amount of assets under the liens). See Note 6 for a description of other obligations that are supported by asset liens.

As discussed immediately above, the aggregate fair values of liabilities under derivative agreements with credit risk-related contingent features, including cross-default provisions, totaled $2.059 billion and $2.273 billion as of March 31, 2011 and December 31, 2010, respectively. This amount is before consideration of cash and letter of credit collateral posted, net accounts receivable and derivative assets under netting arrangements and assets under related liens.

Some commodity derivative contracts contain credit risk-related contingent features that do not provide for specific amounts to be posted if the features are triggered. These provisions include material adverse change, performance assurance, and other clauses that generally provide counterparties with the right to request additional credit enhancements. The amounts disclosed above exclude credit risk-related contingent features that do not provide for specific amounts or exposure calculations.

TCEH has significant concentrations of credit risk with the counterparties to its derivative contracts. As of March 31, 2011, total credit risk exposure to all counterparties related to derivative contracts totaled $4.3 billion (including associated accounts receivable). The net exposure to those counterparties totaled $1.4 billion as of March 31, 2011 after taking into effect master netting arrangements, setoff provisions and collateral. The net exposure, assuming setoff provisions in the event of default across all EFH Corp. consolidated subsidiaries, totaled $1.3 billion. As of March 31, 2011, the credit risk exposure to the banking and financial sector represented 95% of the total credit risk exposure, a significant amount of which is related to the long-term hedging program, and the largest net exposure to a single counterparty totaled $559 million. Exposure to the banking and financial sector counterparties is considered to be within an acceptable level of risk tolerance because a significant majority of this exposure is with counterparties with credit ratings of “A” or better. However, this concentration increases the risk that a default by any of these counterparties would have a material adverse effect on our financial condition, results of operations and liquidity.

The transactions with these counterparties contain certain provisions that would require the counterparties to post collateral in the event of a material downgrade in their credit rating. We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies specify authorized risk mitigation tools including, but not limited to, use of standardized master netting contracts and agreements that allow for netting of positive and negative exposures associated with a single counterparty. Credit enhancements such as parent guarantees, letters of credit, surety bonds, liens on assets and margin deposits are also utilized. Prospective material adverse changes in the payment history or financial condition of a counterparty or downgrade of its credit quality result in the reassessment of the credit limit with that counterparty. The process can result in the subsequent reduction of the credit limit or a request for additional financial assurances. An event of default by one or more counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts are owed to the counterparties related to the derivative contracts or delays in receipts of expected settlements if the counterparties owe amounts to us.

Net pension and OPEB costs for the three months ended March 31, 2011 and 2010 are comprised of the following:

The discount rates reflected in net pension and OPEB costs in 2011 are 5.50% and 5.55%, respectively. The expected rates of return on pension and OPEB plan assets reflected in the 2011 cost amounts are 7.7% and 7.1%, respectively.

We made cash contributions related to our pension and OPEB plans totaling $14 million and $6 million, respectively, in the first quarter of 2011, of which $18 million was contributed by Oncor. We expect to make additional contributions of $161 million and $19 million, respectively, in the remainder of 2011, of which $173 million is expected to be contributed by Oncor.

Our operations are aligned into two reportable business segments: Competitive Electric and Regulated Delivery. The segments are managed separately because they are strategic business units that offer different products or services and involve different risks.

The Competitive Electric segment is engaged in competitive market activities consisting of electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities, and retail electricity sales to residential and business customers, all largely in Texas. These activities are conducted by TCEH.

The Regulated Delivery segment is engaged in regulated electricity transmission and distribution operations in Texas. These activities are conducted by Oncor, including its wholly owned bankruptcy-remote financing subsidiary. See Note 3 for discussion of the reporting of Oncor Holdings and, accordingly, the Regulated Delivery segment, as an equity method investment.

Corporate and Other represents the remaining nonsegment operations consisting primarily of general corporate expenses and interest on EFH Corp. (parent entity), EFIH and EFCH debt.

The accounting policies of the business segments are the same as those described in the summary of significant accounting policies in Note 1 above and in Note 1 to Financial Statements in the 2010 Form 10-K. We evaluate performance based on income from continuing operations. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices.

In December 2010, in consideration of the desire to enhance retention incentives, EFH Corp. offered employee grantees of all stock options (excluding named executive officers and a limited number of other employees) the right to exchange their vested and unvested options for restricted stock units payable in shares (at a ratio of two options for each stock unit). The restricted stock units vest as common shares of EFH Corp. in September 2014. The exchange offer closed in late February 2011, and substantially all eligible employees accepted the offer, which resulted in the issuance of 9.4 million restricted stock units in exchange for 16.1 million Time-Based Options (including 5.2 million that were vested) and 2.8 million Performance-Based Options (including 2.0 million that were vested). In addition, 0.4 million restricted stock units were issued as compensation to management employees and directors in the three months ended March 31, 2011.

In addition, 0.4 million and 0.2 million shares of common stock were awarded as compensation in the three months ended March 31, 2011 and 2010, respectively, to board members. Of the restricted stock units payable in cash previously granted to certain management employees, 0.6 million vested in the three months ended March 31, 2010.

Expenses recognized for restricted stock units payable in shares totaled $0.6 million for the three months ended March 31, 2011. Expenses recognized for options granted totaled $1.1 million and $7 million for the three months ended March 31, 2011 and 2010, respectively. Expenses recognized for deferred shares and other common stock awarded as compensation totaled $1.8 million and $2 million for the three months ended March 31, 2011 and 2010, respectively. In addition, as a result of the decline in value of EFH Corp. shares, in the three months ended March 31, 2011, a credit of $3.5 million was recorded related to restricted stock units payable in cash.

Nuclear Decommissioning Trust — Investments in a trust that will be used to fund the costs to decommission the Comanche Peak nuclear generation plant are carried at fair value. Decommissioning costs are being recovered from Oncor’s customers as a delivery fee surcharge over the life of the plant and deposited in the trust fund. Net gains and losses on investments in the trust fund are offset by a corresponding change in receivables from/payables due to unconsolidated subsidiary, reflecting changes in Oncor’s regulatory asset/liability. A summary of investments in the fund follows:

Debt securities held as of March 31, 2011 mature as follows: $110 million in one to five years, $45 million in five to ten years and $69 million after ten years.

The following table summarizes proceeds from sales of available-for-sale securities and the related realized gains and losses from such sales.

As of March 31, 2011 and December 31, 2010, property, plant and equipment of $20.2 billion and $20.4 billion, respectively, is stated net of accumulated depreciation and amortization of $4.5 billion and $4.2 billion, respectively.

These liabilities primarily relate to nuclear generation plant decommissioning, land reclamation related to lignite mining, removal of lignite/coal-fueled plant ash treatment facilities and generation plant asbestos removal and disposal costs. There is no earnings impact with respect to the recognition of the asset retirement costs for nuclear decommissioning, as all costs are recoverable through the regulatory process as part of Oncor’s rates.

The following table summarizes the changes to these obligations, reported in other current liabilities and other noncurrent liabilities and deferred credits in the balance sheet, during the three months ended March 31, 2011:

The balance of other noncurrent liabilities and deferred credits consists of the following:

The conclusion of all issues contested with the IRS from the 1997 through 2002 audit, including IRS Joint Committee review, is expected to occur before the end of 2012. Upon such conclusion, we expect to reduce the liability for uncertain tax positions by approximately $700 million with an offsetting decrease in deferred tax assets that arose largely from previous payments of alternative minimum taxes. No cash income tax liability is expected related to the conclusion of the 1997 through 2002 audit. Other than the items discussed immediately above, we do not expect the total amount of liabilities recorded related to uncertain tax positions to significantly increase or decrease within the next 12 months.

Unfavorable Purchase and Sales Contracts – The amortization of unfavorable purchase and sales contracts totaled $6 million in both the three months ended March 31, 2011 and 2010. Favorable purchase and sales contracts are recorded as intangible assets (see Note 4).

The estimated amortization of unfavorable purchase and sales contracts for each of the five fiscal years from December 31, 2010 is as follows:

As of March 31, 2011, EFH Corp. had outstanding $359 million principal amount of EFH Corp. 10.875% Notes and $571 million principal amount of EFH Corp. Toggle Notes (collectively, the EFH Corp. Senior Notes) and $115 million principal amount of EFH Corp. 9.75% Notes and $1.061 billion principal amount of EFH Corp. 10% Notes (collectively, the EFH Corp. Senior Secured Notes). The EFH Corp. Senior Notes and Senior Secured Notes are unconditionally guaranteed by EFCH and EFIH, 100% owned subsidiaries of EFH Corp. (collectively, the Guarantors) on an unsecured basis except for EFIH’s guarantee of the EFH Corp. Senior Secured Notes, which is secured by a pledge of all membership interests and other investments EFIH owns or holds in Oncor Holdings or any of Oncor Holdings’ subsidiaries as described in Note 6. The guarantees issued by the Guarantors are full and unconditional, joint and several guarantees of the EFH Corp. Senior Notes and Senior Secured Notes. The guarantees by EFCH and the guarantee of the EFH Corp. Senior Notes by EFIH rank equally with any senior unsecured indebtedness of the Guarantors and rank effectively junior to all of the secured indebtedness of the Guarantors to the extent of the assets securing that indebtedness. All other subsidiaries of EFH Corp., either direct or indirect, do not guarantee the EFH Corp. Senior Notes and EFH Corp. Senior Secured Notes (collectively, the Non-Guarantors). The indentures governing the EFH Corp. Senior Notes and EFH Corp. Senior Secured Notes contain certain restrictions, subject to certain exceptions, on EFH Corp.’s ability to pay dividends or make investments. See Note 8.

The following tables have been prepared in accordance with Regulation S-X Rule 3-10, “Financial Statements of Guarantors and Issuers of Guaranteed Securities Registered or Being Registered” in order to present the condensed consolidating statements of income and cash flows of EFH Corp. (the Parent/Issuer), the Guarantors and the Non-Guarantors for the three months ended March 31, 2011 and 2010 and the consolidating balance sheets as of March 31, 2011 and December 31, 2010 of the Parent/Issuer, the Guarantors and the Non-Guarantors. Investments in consolidated subsidiaries are accounted for under the equity method. The presentations reflect the application of SEC Staff Accounting Bulletin Topic 5-J, “Push Down Basis of Accounting Required in Certain Limited Circumstances,” including the effects of the push down of the $930 million principal amount of EFH Corp. Senior Notes and $771 million principal amount of the EFH Corp. Senior Secured Notes to the Guarantors as of both March 31, 2011 and December 31, 2010 (see Note 6). Amounts pushed down reflect Merger-related debt and additional debt guaranteed by the Guarantors that was issued by EFH Corp. to refinance Merger-related or other debt existing at the time of the Merger.

EFH Corp. (Parent) received no dividends/distributions from its consolidated subsidiaries in the three months ended March 31, 2011 or 2010.

The following discussion and analysis of our financial condition and results of operations for the three months ended March 31, 2011 and 2010 should be read in conjunction with our consolidated financial statements and the notes to those statements.

All dollar amounts in the tables in the following discussion and analysis are stated in millions of US dollars unless otherwise indicated.

We are a Dallas, Texas-based holding company with operations consisting principally of our TCEH and Oncor subsidiaries. TCEH is a holding company for subsidiaries engaged in competitive electricity market activities largely in Texas including electricity generation, wholesale energy sales and purchases, commodity risk management and trading activities, and retail electricity sales. Oncor is a majority-owned (approximately 80%) subsidiary engaged in regulated electricity transmission and distribution operations in Texas. Various “ring-fencing” measures have been taken to enhance the credit quality of Oncor. See Notes 1 and 3 to Financial Statements for a description of the material features of these “ring-fencing” measures and for a discussion of the reporting of our investment in Oncor (and its majority owner, Oncor Holdings) as an equity method investment.

We have aligned and report our business activities as two operating segments: the Competitive Electric segment and the Regulated Delivery segment. The Competitive Electric segment is principally comprised of TCEH. The Regulated Delivery segment is comprised of Oncor Holdings and its subsidiaries.

See Note 14 to Financial Statements for further information regarding reportable business segments.

Natural Gas Prices and Long-Term Hedging Program — TCEH has a long-term hedging program designed to reduce exposure to changes in future electricity prices due to changes in the price of natural gas. Under the program, the company has entered into market transactions involving natural gas-related financial instruments, and as of March 31, 2011, has effectively sold forward approximately 1.0 billion MMBtu of natural gas (equivalent to the natural gas exposure of approximately 121,000 GWh at an assumed 8.0 market heat rate) at weighted average annual hedge prices ranging from $7.19 per MMBtu to $7.80 per MMBtu.

These transactions, as well as forward power sales, have effectively hedged an estimated 48% of the natural gas price exposure related to TCEH’s expected generation output for the period beginning April 1, 2011 and ending December 31, 2015 (on an average basis for such period and assuming an 8.0 market heat rate). The hedges were entered into with the continuing expectation that wholesale electricity prices in ERCOT will be highly correlated with natural gas prices, which is expected to be the marginal fuel for the purpose of setting electricity prices generally 75% to 90% of the time. If the correlation changes in the future, the cash flows targeted under the long-term hedging program may not be achieved.

The long-term hedging program is comprised primarily of contracts with prices based on the New York Mercantile Exchange (NYMEX) Henry Hub pricing point. However, because there are other local and regional natural gas pricing points such as Houston Ship Channel, future wholesale power prices in ERCOT may not correlate as closely to the Henry Hub pricing as other pricing points, which could decrease the effectiveness of the positions in the long-term hedging program in mitigating power price exposure. The company has hedged approximately 95% of the Houston Ship Channel versus Henry Hub pricing point risk for 2011.

The company has entered into related put and call transactions (referred to as collars), primarily for 2014, that effectively hedge natural gas prices within a range. These transactions represented 15% of the positions in the long-term hedging program as of March 31, 2011, with the approximate weighted average strike prices under the collars being a floor of $7.80 per MMBtu and a ceiling of $11.75 per MMBtu. The company expects to use financial instruments, including collars, in future hedging activity under the long-term hedging program.

The following table summarizes the natural gas hedges in the long-term hedging program as of March 31, 2011:

Changes in the fair value of the instruments in the long-term hedging program are being recorded as unrealized gains and losses in net gain (loss) from commodity hedging and trading activities in the statement of income, which has and could continue to result in significant volatility in reported net income. Based on the size of the long-term hedging program as of March 31, 2011, a $1.00/MMBtu change in natural gas prices across the hedged period would result in the recognition of up to $1.0 billion in pretax unrealized mark-to-market gains or losses.

Unrealized mark-to-market net gains (losses) related to the long-term hedging program were as follows:

The cumulative unrealized mark-to-market net gain related to positions in the long-term hedging program totaled $2.801 billion and $3.143 billion as of March 31, 2011 and December 31, 2010, respectively. See discussion below under “Results of Operations” for realized net gains from hedging activities, which amounts are largely related to the long-term hedging program.

Given the volatility of natural gas prices, it is not possible to predict future reported unrealized mark-to-market gains or losses and the actual gains or losses that will ultimately be realized upon settlement of the hedge positions in future years. If natural gas prices at settlement are lower than the prices of the hedge positions, the hedges are expected to mitigate the otherwise negative effect on earnings of lower wholesale electricity prices. However, if natural gas prices at settlement are higher than the prices of the hedge positions, the hedges are expected to dampen the otherwise positive effect on earnings of higher wholesale electricity prices and will in this context be viewed as having resulted in an opportunity cost.

The significant cumulative unrealized mark-to-market net gain related to positions in the long-term hedging program reflects declining forward market natural gas prices. Forward natural gas prices have generally trended downward since mid-2008 as shown in the table of forward NYMEX Henry Hub natural gas prices below. While the long-term hedging program is designed to mitigate the effect on earnings of low wholesale electricity prices, depressed forward natural gas prices are challenging to the long-term profitability of our generation assets. Specifically, these lower natural gas prices and the correlated effect in ERCOT on wholesale electricity prices could have a material adverse impact on the overall profitability of our generation assets for periods in which we have less significant hedge positions (i.e., beginning in 2013). In addition, a continuation or worsening of these market conditions would limit our ability to hedge our wholesale electricity revenues at sufficient price levels to support our interest payments and debt maturities and could adversely impact our ability to refinance our substantial long-term debt that matures in 2013 through 2016.

As of March 31, 2011, more than 95% of the long-term hedging program transactions were directly or indirectly secured by a first-lien interest in TCEH’s assets (including the transactions supported by the TCEH Commodity Collateral Posting Facility – see discussion below under “Financial Condition — Liquidity and Capital Resources”), thereby reducing the cash and letter of credit collateral requirements for the hedging program.

The following sensitivity table provides estimates of the potential impact (in $ millions) of movements in natural gas and certain other commodity prices and market heat rates on realized pre-tax earnings for the periods presented. The estimates related to price sensitivity are based on TCEH’s unhedged position and forward prices as of March 31, 2011, which for natural gas reflects estimates of electricity generation less amounts hedged through the long-term natural gas hedging program and amounts under existing wholesale and retail sales contracts. On a rolling twelve-month basis, the substantial majority of retail sales under month-to-month arrangements are deemed to be under contract.

Liability Management Program — As of March 31, 2011, EFH Corp. and its subsidiaries (excluding Oncor and its subsidiaries) had $35.4 billion principal amount of long-term debt outstanding. In October 2009, we implemented a liability management program focused on improving our balance sheet by reducing debt and extending debt maturities through debt exchanges, repurchases and issuances. Activities under the liability management program do not include debt issued by Oncor or its subsidiaries.

In transactions completed on April 19, 2011, $17.8 billion of maturities and commitments under the TCEH Senior Secured Facilities were extended three years, including $16.4 billion of term loans and deposit letter of credit loans from October 2014 to October 2017 and $1.4 billion of commitments (under which borrowings totaled $452 million upon the closing of the transactions) under the TCEH Revolving Credit Facility from October 2013 to October 2016. In addition, proceeds from the issuances in April 2011 of $1.750 billion principal amount of TCEH Senior Secured Notes were used to repay $1.604 billion of borrowings under the TCEH Senior Secured Facilities. Further, in private exchanges in April 2011, EFIH and EFIH Finance issued $406 million principal amount of EFIH 11% Senior Secured Second Lien Notes due 2021 in exchange for $428 million of EFH Corp. debt consisting of $163 million principal amount of EFH Corp. 10.875% Notes, $229 million principal amount of EFH Corp. Toggle Notes and $36 million principal amount of EFH Corp. 5.55% Series P Senior Notes due 2014.

Liability management activities since October 2009 include debt exchange and repurchase activities as follows (except where noted, debt amounts are principal amounts):

Since inception, the transactions resulted in the capture of $2.0 billion of debt discount.

See Note 6 to Financial Statements for further discussion of the transactions completed under our liability management program in 2011.

Wholesale Market Design – Nodal Market — In accordance with a rule adopted by the PUCT in 2003, ERCOT developed a new wholesale market, using a stakeholder process, designed to assign congestion costs to the market participants causing the congestion. The nodal market design was implemented December 1, 2010. Under this new market design, ERCOT:

ERCOT previously had a zonal wholesale market structure consisting of four geographic zones. The new location-based congestion-management market is referred to as a “nodal” market because wholesale pricing differs across the various nodes on the transmission grid instead of across the geographic zones. There are over 500 nodes in the ERCOT market. The nodal market design was implemented in conjunction with transmission improvements designed to reduce current congestion. We are fully certified to participate in both the “day-ahead” and “real-time markets.” Additionally, all of our operational generation assets and our qualified scheduling entities are certified and operate in the nodal market. While the initial implementation of the nodal market has not had a material impact on our profitability, we cannot predict the ultimate impact of the market design on our operations or financial results, and it could ultimately have an adverse impact on the profitability and value of our competitive business and/or our liquidity, particularly if such change ultimately results in lower revenue due to lower wholesale power prices, increased costs to service end-user electricity demand or increased collateral posting requirements with ERCOT. The opening of the nodal market resulted in an increase of approximately $200 million in the amount of letters of credit posted with ERCOT to support our market participation.

As discussed above, the nodal market design includes the establishment of a “day-ahead market” and hub trading prices to facilitate hedging and trading of electricity by participants. Under the previous zonal market, volumes under our nontrading bilateral purchase and sales contracts, including contracts intended as hedges, were scheduled as physical power with ERCOT and, therefore, reported gross as wholesale revenues or purchased power costs. In conjunction with the transition to the nodal market, unless the volumes represent physical deliveries to retail and wholesale customers or purchases from counterparties, these contracts are reported on a net basis in the income statement in net gain/(loss) from commodity hedging and trading activities. As a result of these changes, reported wholesale revenues and purchased power costs (and the associated volumes) in 2011 will be materially less than amounts reported in prior periods.

TCEH Interest Rate Swap Transactions — As of March 31, 2011, TCEH has entered into a series of interest rate swaps that effectively fix the interest rates at between 5.6% and 8.3% on $17.87 billion principal amount of its senior secured debt maturing from 2012 to 2014. Swaps related to an aggregate $2.60 billion principal amount of debt expired or were terminated in the three months ended March 31, 2011, and swaps related to an aggregate $4.67 billion principal amount of debt (growing to $8.64 billion over time, primarily as existing swaps expire) were entered into in the same period. Taking into consideration these swap transactions, 7% of our consolidated long-term debt portfolio as of March 31, 2011 was exposed to variable interest rate risk through 2014. Subsequent to the end of the quarter through April 27, 2011, TCEH entered into additional swaps related to an aggregate $781 million principal amount of debt (growing to $1.936 billion over time to October 2014, primarily as existing swaps expire). We may enter into additional interest rate hedges from time to time.

As of March 31, 2011, TCEH has also entered into interest rate basis swap transactions, which further reduce the fixed (through swaps) borrowing costs, related to an aggregate of $12.70 billion principal amount of senior secured debt. Swaps related to an aggregate $2.50 billion principal amount of debt expired in the three months ended March 31, 2011.

Unrealized mark-to-market net gains and losses related to all TCEH interest rate swaps, which are reported in interest expense and related charges, totaled $142 million in net gains and $107 million in net losses in the three months ended March 31, 2011 and 2010, respectively. The cumulative unrealized mark-to-market net liability related to all TCEH interest rate swaps totaled $1.277 billion and $1.419 billion as of March 31, 2011 and December 31, 2010, respectively, of which $94 million and $105 million (both pre-tax), respectively, was reported in accumulated other comprehensive income. These fair values can change materially as market conditions change, which could result in significant volatility in reported net income. See discussion in Note 6 to Financial Statements regarding interest rate swap transactions.

Recent EPA Actions — In 2005, the EPA published a final rule requiring reductions of mercury emissions from lignite/coal-fueled generation plants. The Clean Air Mercury Rule (CAMR) was based on a nationwide cap and trade approach. The mercury reductions were required to be phased in between 2010 and 2018. In March 2008, the US Court of Appeals for the D.C. Circuit (the D.C. Circuit Court) vacated CAMR. In February 2009, the US Supreme Court refused to hear the appeal of the D.C. Circuit Court’s ruling. The EPA agreed in a consent decree submitted for court approval to propose Maximum Achievable Control Technology (MACT) rules by March 2011 and finalize those rules by November 2011. In March 2011, the EPA issued for comment a proposed rule for coal and oil-fueled electric generating units (Utility MACT). Once finalized, this rule could require substantial control equipment retrofits on our lignite coal-fueled generation units within three to four years of the effective date of the rule, which as previously disclosed could require material capital expenditures. We cannot predict the substance of the final Utility MACT rule, or its impact on our facilities, financial condition or results of operations.

Diversion, impoundment and withdrawal of water for cooling and other purposes are subject to the jurisdiction of the TCEQ and the EPA. We believe we possess all necessary permits for these activities from the TCEQ for our present operations. Clean Water Act Section 316(b) regulations pertaining to existing water intake structures at large generation facilities were published by the EPA in 2004. As prescribed in the regulations, we began implementing a monitoring program to determine the future actions that might need to be taken to comply with these regulations. In January 2007, a federal court ruled against the EPA in a lawsuit brought by environmental groups challenging aspects of these regulations, and in July 2007, the EPA announced that it was suspending the regulations pending further rulemaking. The US Supreme Court issued a decision in April 2009 reversing the federal court’s decision, in part, and finding that the EPA permissibly used cost-benefit analysis in the Section 316(b) regulations. In the absence of regulations, the EPA has instructed the states implementing the Section 316(b) program to use their best professional judgment in reviewing applications and issuing permits under Section 316(b). In April 2010, the EPA entered into a settlement agreement that requires it to propose new rules under Section 316(b) by March 2011 and to finalize those rules by July 2012. In March 2011, the EPA issued for comment the proposed regulations. Although the proposed rule does not mandate a certain control technology, it does require site-specific assessments of technology feasibility on a case-by-case basis at the state level. Compliance with this rule would be required beginning eight years following promulgation. We cannot predict the substance of the final regulations or the impact they may have on our financial condition or results of operations.

In 2005, the EPA published a final rule (the Clean Air Interstate Rule or CAIR) requiring states to reduce emissions of sulfur dioxide (SO₂) and nitrogen oxide (NO_x) that significantly contributed to or interfered with maintenance of the EPA’s National Ambient Air Quality Standards (NAAQS) for fine particulate matter and/or ozone in any downwind state. In 2008, the D.C. Circuit Court remanded CAIR to the EPA, but allowed the rule to continue until such time as the EPA issued a final replacement rule. In August 2010, the EPA issued for comment a proposed rule called the Clean Air Transport Rule (CATR). As proposed, CATR did not include the State of Texas in its annual SO₂ and NO_x program to address downwind fine particulate impacts. However, the EPA expressly solicited comment as to whether the State of Texas should be included in the annual program. On April 13, 2011, the EPA released a proposed rule that would disapprove Texas’ State Implementation Plan (SIP) submittal regarding compliance with the interstate transport requirements of the Clean Air Act as they pertain to the 2006 NAAQS for fine particulate matter. In this proposed rule, the EPA suggested that it might seek to include the State of Texas in the CATR annual program through imposition of a Federal Implementation Plan as a means of remedying Texas’ alleged failure to submit an adequate SIP. The final CATR is expected to be issued later this year and could require us to incur material capital expenditures. Compliance with CATR is currently proposed to start in January 2012. However, we cannot predict with certainty whether the State of Texas will be included in CATR or, if included, the impact that such inclusion would have on our facilities, financial condition or results of operations.

Oncor Technology Initiatives — Oncor continues to invest in technology initiatives that include development of a modernized grid through the replacement of existing meters with advanced digital metering equipment and development of advanced digital communication, data management, real-time monitoring and outage detection capabilities. This modernized grid is expected to produce electricity service reliability improvements and provide the potential for additional products and services from REPs that will enable businesses and consumers to better manage their electricity usage and costs. Oncor’s plans provide for the full deployment of over three million advanced meters to all residential and most non-residential retail electricity customers in Oncor’s service area. The advanced meters can be read remotely, rather than by a meter reader physically visiting the location of each meter. Advanced meters facilitate automated demand side management, which allows consumers to monitor the amount of electricity they are consuming and adjust their electricity consumption habits.

As of March 31, 2011, Oncor has installed approximately 1,635,000 advanced digital meters, including approximately 121,000 during the three months ended March 31, 2011. As the new meters are integrated, Oncor reports 15-minute interval, billing-quality electricity consumption data to ERCOT for market settlement purposes. The data makes it possible for REPs to support new programs and pricing options. Cumulative capital expenditures for the deployment of the advanced meter system totaled $390 million as of March 31, 2011, including $30 million in the first quarter of 2011. Oncor expects to complete installations of the remaining approximately 1.4 million advanced meters by the end of 2012.

Oncor Rate Review Filed with the PUCT — In January 2011, Oncor filed for a rate review with the PUCT and 203 cities based on a test year ended June 30, 2010. The PUCT, with Oncor’s input and that of the cities and other participating parties, established a procedural schedule for the review. In April 2011, Oncor filed, and the administrative law judges in the rate review granted, a motion requesting abatement of the procedural schedule in the rate review on the grounds that Oncor and the parties to the rate review had reached a Memorandum of Settlement that would settle and resolve all issues in the rate review. Oncor expects to file a stipulation in late April or early May 2011 that incorporates the Memorandum of Settlement along with proposed tariffs. The stipulation and related tariffs must be approved by the PUCT. The terms of the settlement include an approximate $137 million base rate increase and additional provisions to address franchise fees and other expenses. The settlement would result in an impact of less than 1% on an average residential monthly bill of 1,300 kWh for a TXU Energy customer. Approximately $93 million of the increase would become effective by July 1, 2011, and the remainder would become effective by January 1, 2012. The settlement does not change Oncor’s authorized regulatory capital structure of 60% debt and 40% equity or its authorized return on equity of 10.25%. See “Regulatory Matters” below for further discussion.

Other Oncor Matters with the PUCT — See discussion of these matters, including the construction of CREZ-related transmission lines, below under “Regulatory Matters.”

Consolidated Financial Results – Three Months Ended March 31, 2011 Compared to Three Months Ended March 31, 2010

See comparison of results of the Competitive Electric segment for discussion of variances in: operating revenues; fuel, purchased power costs and delivery fees; net gain (loss) from commodity hedging and trading activities, operating costs; depreciation and amortization, and franchise and revenue-based taxes.

SG&A expenses decreased $22 million, or 12%, to $165 million in 2011. The decrease was driven by lower retail bad debt expense reflecting improved customer mix and the impacts on prior year collections of delayed billings during the implementation of a retail customer information management system.

Interest income decreased $8 million to $2 million in 2011 reflecting interest in 2010 on $465 million in collateral under a funding arrangement settled in March 2010.

Interest expense and related charges decreased $311 million, or 33%, to $643 million in 2011 reflecting a $142 million unrealized mark-to-market net gain related to interest rate swaps in 2011 compared to a $107 million net loss in 2010, a $19 million decrease in noncash amortization of losses on interest rate swaps dedesignated as cash flow hedges as well as lower interest expense resulting from reduced debt under the liability management program as described above under “Significant Activities and Events,” partially offset by a $23 million decrease in capitalized interest. See Note 15 to Financial Statements.

Income tax benefit totaled $215 million on a pretax loss in 2011 and income tax expense totaled $203 million on pretax income in 2010. The effective tax rates were 34.3% in 2011 and 41.0% in 2010. The decrease in the effective tax rate in 2011 was driven by the effect of interest accrued on uncertain tax positions in both years and an $8 million deferred tax charge in 2010 related to the Patient Protection and Affordable Care Act.

Equity in earnings of unconsolidated subsidiaries (net of tax) decreased $13 million to $50 million in 2011 driven by lower earnings of Oncor, which reflected milder weather, higher depreciation and operating costs and increased interest expense, partially offset by higher revenue rates.

In communications with investors, we use a non-GAAP earnings measure that reflects adjustments to earnings reported in accordance with US GAAP in order to review underlying operating performance. These adjusting items, which are generally noncash, consist of unrealized mark-to-market gains and losses, impairment charges, debt extinguishment gains and other charges, credits or gains that are unusual or nonrecurring. All such items and related amounts are disclosed in our annual report on Form 10-K and quarterly reports on Form 10-Q. Our communications with investors also reference “Adjusted EBITDA,” which is a non-GAAP measure used in calculation of ratios in covenants of certain of our debt securities (see “Financial Condition – Liquidity and Capital Resources – Financial Covenants, Credit Rating Provisions and Cross Default Provisions” below).

Competitive Electric Segment – Financial Results — Three Months Ended March 31, 2011 Compared to Three Months Ended March 31, 2010

As discussed above under “Significant Activities and Events,” the nodal wholesale market design implemented by ERCOT in December 2010 resulted in operational changes that facilitate hedging and trading of power. As part of ERCOT’s transition to a nodal wholesale market, volumes under nontrading bilateral purchase and sales contracts are no longer scheduled as physical power with ERCOT. As a result of these changes in market operations, reported wholesale revenues and purchased power costs in 2011 will be materially less than amounts reported in prior periods. Effective with the nodal market implementation, if volumes delivered to our retail and wholesale customers are less than our generation volumes (as determined on a daily settlement basis), we record additional wholesale revenues. Conversely, if volumes delivered to our retail and wholesale customers exceed our generation volumes, we record additional purchased power costs. The resulting additional wholesale revenues or purchased power costs are offset in net gain/(loss) from commodity hedging and trading activities.

Retail electricity revenues decreased $218 million or 15%, to $1.203 billion and reflected the following:

Wholesale electricity revenues decreased $108 million, or 21%, to $395 million in 2011. The decrease is primarily attributable to the nodal market change described above. The decrease was partially offset by higher production from the new lignite-fueled generation units and by $18 million in lower unrealized losses related to physical derivative sales contracts as discussed in footnote (b) to the “Revenue and Commodity Hedging and Trading Activities” table above.

Fuel, purchased power costs and delivery fees decreased $217 million, or 21%, to $830 million in 2011. Purchased power costs decreased $226 million driven by the effect of the nodal market change described above. This decrease was partially offset by higher purchased power prices during generation outages resulting from a severe winter storm in early February 2011. Delivery fees declined $30 million reflecting lower retail volumes. These decreases were partially offset by $24 million in higher fuel costs due primarily to higher prices and the effect of the new lignite-fueled generation units and $27 million in lower unrealized gains related to physical derivative commodity purchase contracts as described in footnote (b) to the “Revenue and Commodity Hedging and Trading Activities” table above.

Overall baseload generation production increased 8% in 2011 reflecting a 9% increase in lignite/coal-fueled production driven by increased production from the newly constructed generation facilities.

Following is an analysis of amounts reported as net gain (loss) from commodity hedging and trading activities for the three months ended March 31, 2011 and 2010, which totaled $94 million in net losses and $1.213 billion in net gains, respectively:

Three Months Ended March 31, 2011 — Unrealized mark-to-market net losses totaling $322 million included:

Three Months Ended March 31, 2010 — Unrealized mark-to-market net gains totaling $978 million included:

Unrealized gains and losses that are related to physical derivative commodity contracts and are reported as revenues and purchased power costs, as required by accounting rules, totaled $6 million and $15 million in net gains in 2011 and 2010, respectively.

Operating costs increased $19 million, or 10%, to $216 million in 2011. The increase reflected $9 million in incremental expense related to the new generation units. The balance of the increase was driven by $6 million in implementation costs for new technology systems and process improvements for generation facilities, $2 million in expenses for periodic major inspections of natural gas generation units, and $2 million in various other operating cost variances.

Depreciation and amortization increased $25 million, or 7%, to $362 million in 2011. The increase reflected $15 million in incremental depreciation from a new generation unit placed in service in May 2010 and $10 million in increased depreciation at lignite/coal generation units resulting from additions and replacements.

SG&A expenses decreased $21 million, or 11%, to $162 million in 2011. The decrease was driven by lower retail bad debt expense reflecting improved customer mix and the impacts on prior year collections of delayed billings during the implementation of a retail customer information management system.

Other income totaled $31 million in 2011 and $14 million in 2010. Other income in 2011 included $21 million related to the settlement of bankruptcy claims against a counterparty and $7 million for a property damage claim. Other income in 2010 included a $7 million gain associated with the sale of a partial interest in a business and a $5 million refund of sales taxes related to prior years. See Note 15 to Financial Statements.

Other deductions totaled $2 million in 2011 and $6 million in 2010. See Note 15 to Financial Statements.

Interest income increased $5 million to $27 million in 2011 reflecting higher notes receivable balances from affiliates.

Interest expense and related charges decreased $248 million, or 32%, to $529 million in 2011 reflecting a $142 million unrealized mark-to-market net gain related to interest rate swaps in 2011 compared to a $107 million net loss in 2010 and a $19 million decrease in noncash amortization of losses on interest rate swaps dedesignated as cash flow hedges, partially offset by a $23 million decrease in capitalized interest.

Income tax benefit totaled $166 million on a pretax loss in 2011 compared to income tax expense of $248 million on pretax income in 2010. The effective rate was 34.2% and 36.5% in 2011 and 2010, respectively. The decrease in the effective rate reflected interest accrued on uncertain tax positions in both years and the absence of a production activities deduction in 2011 due to an expected tax loss.

After-tax results for the segment declined $751 million to a net loss of $320 million in 2011 reflecting the decline in results from commodity hedging and trading activities due to unrealized mark-to-market net losses in 2011 compared to unrealized net gains in 2010, partially offset by an opposite change in unrealized mark-to-market values of interest rate swaps reported in interest expense.

The table below summarizes the changes in commodity contract assets and liabilities for the three months ended March 31, 2011 and 2010. The net change in these assets and liabilities, excluding “other activity” as described below, represents $316 million in unrealized net losses in 2011 and $993 million in unrealized net gains in 2010 arising from mark-to-market accounting for positions in the commodity contract portfolio. The portfolio consists primarily of economic hedges but also includes trading positions.

Maturity Table — The following table presents the net commodity contract asset arising from recognition of fair values under mark-to-market accounting as of March 31, 2011, scheduled by the source of fair value and contractual settlement dates of the underlying positions.

The “prices actively quoted” category reflects only exchange traded contracts for which active quotes are readily available. The “prices provided by other external sources” category represents forward commodity positions valued using prices for which over-the-counter broker quotes are available in active markets. Over-the-counter quotes for power in ERCOT that are deemed active markets (excluding the West hub) generally extend through 2013 and over-the-counter quotes for natural gas generally extend through 2016, depending upon delivery point. The “prices based on models” category contains the value of all nonexchange traded options, valued using option pricing models. In addition, this category contains other contractual arrangements that may have both forward and option components, as well as other contracts that are valued using proprietary long-term pricing models that utilize certain market based inputs. See Note 9 to Financial Statements for fair value disclosures and discussion of fair value measurements.

Cash Flow — Three Months Ended March 31, 2011 Compared to Three Months Ended March 31, 2010 — Cash provided by operating activities increased $226 million to $328 million in 2011. The increase reflected the effect of amended accounting standards related to the accounts receivable securitization program (see Note 5 to Financial Statements), under which the $383 million of funding under the program at the January 1, 2010 adoption was reported as a use of operating cash flows and a source of financing cash flows. Excluding this accounting effect, cash provided by operating activities declined $157 million driven by lower cash earnings, which reflected a low wholesale power price environment and the effects of a severe winter storm in February 2011, partially offset by the contribution from the new lignite-fueled generation units.

Depreciation and amortization expense reported in the statement of cash flows exceeded the amount reported in the statement of income by $82 million and $93 million for the three months ended March 31, 2011 and 2010, respectively. The difference represented amortization of nuclear fuel, which is reported as fuel costs in the statement of income consistent with industry practice, and amortization of intangible net assets and debt fair value discounts arising from purchase accounting that is reported in various other income statement line items including operating revenues, fuel and purchased power costs and delivery fees and interest expense and related charges.

Cash used in financing activities totaled $292 million in 2011 compared to cash provided of $57 million in 2010. Activity in 2011 reflected a reduction in net borrowings under the TCEH Revolving Credit Facility. Activity in 2010 included a $383 million source of financing cash flows due to an accounting change related to the accounts receivable securitization program as discussed above, partially offset by net repayments of debt.

See Note 6 to Financial Statements for further detail of short-term borrowings and long-term debt.

Cash used in investing activities totaled $240 million in 2011 compared to cash provided of $9 million in 2010. Investing activities in 2010 reflected a $400 million cash investment posted with a derivative counterparty in 2009 that was returned in 2010. Capital expenditures decreased $179 million to $149 million in 2011 reflecting a decrease in spending related to the construction of new generation facilities.

Debt Financing Activity — Activities related to short-term borrowings and long-term debt during the three months ended March 31, 2011 are as follows (all amounts presented are principal, and repayments and repurchases include amounts related to capital leases and exclude amounts related to debt discount, financing and reacquisition expenses):

See Note 6 to Financial Statements for further detail of long-term debt and other financing arrangements, including amendments to the TCEH Senior Secured Facilities as well as maturity extensions and repayments of borrowings under those facilities in April 2011.

We regularly monitor the capital and bank credit markets for liability management opportunities that we believe will improve our balance sheet, including capturing debt discount and extending debt maturities. As a result, we may engage, from time to time, in liability management transactions. Future activities under the liability management program may include the purchase of our outstanding debt for cash in open market purchases or privately negotiated refinancing/exchange transactions (including pursuant to a Section 10b-5(1) plan) or via public or private exchange or tender offers.

In evaluating whether to undertake any liability management transaction, including any refinancing, we will take into account liquidity requirements, prospects for future access to capital, contractual restrictions, the market price of our outstanding debt and other factors. Any liability management transaction, including any refinancing, may occur on a stand-alone basis or in connection with, or immediately following, other liability management transactions.

Available Liquidity — The following table summarizes changes in available liquidity since December 31, 2010.

See Note 6 to Financial Statements for discussion of transactions in April 2011 related to the TCEH Senior Secured Facilities that resulted in an amendment to the terms of the facilities, three-year extensions of $17.8 billion of maturities of borrowings/commitments, repayment of $1.6 billion of borrowings and the reduction of $646 million of commitments.

The decline in available liquidity since December 31, 2010 was driven by transaction costs of the April 2011 amendment and extension of the TCEH Senior Secured Facilities, which were funded largely by cash on hand.

Pension and OPEB Plan Funding — Pension and OPEB plan funding is expected to total $175 million and $25 million, respectively, in 2011. Oncor is expected to fund $190 million of this amount consistent with its share of the pension liability. We made pension and OPEB contributions of $14 million and $6 million, respectively, in the three months ended March 31, 2011, of which $18 million was contributed by Oncor.

Toggle Notes Interest Election — EFH Corp. and TCEH have the option every six months at their discretion, ending with the interest payment due November 2012, to use the payment-in-kind (PIK) feature of their respective toggle notes in lieu of making cash interest payments. We elected to do so beginning with the May 2009 interest payment as an efficient and cost-effective method to further enhance liquidity. Once EFH Corp. and/or TCEH make a PIK election, the election is valid for each succeeding interest payment period until EFH Corp. and/or TCEH revoke the applicable election. Use of the PIK feature will be evaluated at each election period, taking into account market conditions and other relevant factors at such time.

EFH Corp. will make its May 2011 interest payment and its November 2011 interest payment on the EFH Corp. Toggle Notes by using the PIK feature of those notes. During such applicable interest periods, the interest rate on these notes is increased from 11.25% to 12.00%. EFH Corp. is expected to increase the aggregate principal amount of the notes by $21 million in May 2011 (excluding $151 million principal amount issued to EFIH as holder of $2.525 billion principal amount of EFH Corp. Toggle Notes that is eliminated in consolidation) and is expected to further increase the aggregate principal amount of the notes by $22 million in November 2011 (excluding $161 million principal amount expected to be issued to EFIH). The election is expected to increase liquidity in May 2011 by an amount equal to $19 million (excluding $142 million related to notes held by EFIH) and is expected to further increase liquidity in November 2011 by an amount equal to a currently estimated $20 million (excluding $151 million related to notes held by EFIH), constituting the amounts of cash interest that otherwise would have been payable on the notes. See Note 6 to Financial Statements for discussion of debt exchange transactions in April 2011 that resulted in EFIH acquiring $428 million principal amount of EFH Corp. debt, including $229 million principal amount of EFH Corp. Toggle Notes that are reflected in the amounts related to the May and November 2011 PIK elections.

Similarly, TCEH will make its May 2011 interest payment and its November 2011 interest payment on the TCEH Toggle Notes by using the PIK feature of those notes. During the applicable interest periods, the interest rate on the notes is increased from 10.50% to 11.25%. TCEH is expected to increase the aggregate principal amount of the notes by $79 million in May 2011 and is expected to further increase the aggregate principal amount of the notes by $84 million in November 2011. The election is expected to increase liquidity in May 2011 by an amount equal to $74 million and is expected to further increase liquidity in November 2011 by an amount equal to an estimated $78 million, constituting the amounts of cash interest that otherwise would have been payable on the notes.

Liquidity Effects of Commodity Hedging and Trading Activities — Commodity hedging and trading transactions typically require a counterparty to post collateral if the forward price of the underlying commodity moves such that the hedging or trading instrument held by such counterparty has declined in value. TCEH uses cash, letters of credit, asset-backed liens and other forms of credit support to satisfy such collateral obligations. In addition, TCEH’s Commodity Collateral Posting Facility (CCP facility), an uncapped senior secured revolving credit facility that matures in December 2012, funds the cash collateral posting requirements for a significant portion of the positions in the long-term hedging program not otherwise secured by a first-lien in the assets of TCEH. The aggregate principal amount of the CCP facility is determined by the exposure arising from higher forward market prices, regardless of the amount of such exposure, on a portfolio of certain natural gas hedging transaction volumes. Including those hedging transactions where margin deposits are covered by unlimited borrowings under the CCP facility, as of March 31, 2011, more than 95% of the long-term natural gas hedging program transactions were secured by a first-lien interest in the assets of TCEH that is pari passu with the TCEH Senior Secured Facilities, the effect of which is a significant reduction in the liquidity exposure associated with collateral requirements for those hedging transactions. Due to declines in forward natural gas prices, no amounts were borrowed against the CCP facility as of March 31, 2011 and December 31, 2010. See Note 6 to Financial Statements for more information about the TCEH Senior Secured Facilities, which include the CCP facility.

As of March 31, 2011, TCEH received or posted cash and letters of credit for commodity hedging and trading activities as follows:

With respect to exchange cleared transactions, these transactions typically require initial margin (i.e., the upfront cash and/or letter of credit posted to take into account the size and maturity of the positions and credit quality) in addition to variance margin (i.e., the daily cash margin posted to take into account changes in the value of the underlying commodity). The amount of initial margin required is generally defined by exchange rules. Clearing agents, however, typically have the right to request additional initial margin based on various factors including market depth, volatility and credit quality, which may be in the form of cash, letters of credit, a guaranty or other forms as negotiated with the clearing agent. With respect to cash collateral that is received, such cash collateral is either used for working capital and other corporate purposes, including reducing short-term borrowings under credit facilities, or it is required to be deposited in a separate account and restricted from being used for working capital and other corporate purposes. With respect to over-the-counter transactions, counterparties generally have the right to substitute letters of credit for such cash collateral. In such event, the cash collateral previously posted would be returned to such counterparties thereby reducing liquidity in the event that it was not restricted. As of March 31, 2011, restricted cash collateral held totaled $36 million. See Note 15 to Financial Statements regarding restricted cash.

With the long-term hedging program, increases in natural gas prices generally result in increased cash collateral and letter of credit postings to counterparties. As of March 31, 2011, approximately 400 million MMBtu of positions related to the long-term hedging program were not directly secured on an asset-lien basis and thus have cash collateral posting requirements. The uncapped CCP facility supports the collateral posting requirements related to most of these transactions.

Income Tax Refunds/Payments — Income tax payments related to the Texas margin tax are expected to total approximately $65 million, and net refunds of federal income taxes are expected to total approximately $13 million in the next 12 months. Refunds totaled $31 million in the three months ended March 31, 2011.

We cannot reasonably estimate the ultimate amounts and timing of tax payments associated with uncertain tax positions, but expect that no material federal income tax payments related to such positions will be made in 2011. (See Note 15 to Financial Statements.)

Accounts Receivable Securitization Program — TXU Energy participates in EFH Corp.’s accounts receivable securitization program with financial institutions (the funding entities). In accordance with transfers and servicing accounting standards, the trade accounts receivable amounts under the program are reported as pledged balances and the related funding amounts are reported as short-term borrowings. Under the program, TXU Energy (originator) sells retail trade accounts receivable to TXU Receivables Company, a consolidated wholly-owned bankruptcy-remote direct subsidiary of EFH Corp., which sells undivided interests in the purchased accounts receivable for cash to entities established for this purpose by the funding entities. All new trade receivables under the program generated by the originator are continuously purchased by TXU Receivables Company with the proceeds from collections of receivables previously purchased. Funding under the program totaled $101 million and $96 million as of March 31, 2011 and December 31, 2010, respectively. See Note 5 to Financial Statements for a more complete description of the program including the impact of the program on the financial statements for the periods presented and the contingencies that could result in termination of the program and a reduction of liquidity should the underlying financing be settled.

Distributions from Oncor — Oncor’s distributions to us totaled $16 million and $30 million in the three months ended March 31, 2011 and 2010, respectively. In April 2011, we received an additional $16 million distribution. Until December 31, 2012, distributions paid by Oncor to its members are limited to an amount not to exceed Oncor’s net income determined in accordance with US GAAP, subject to certain defined adjustments. Distributions are further limited by an agreement that Oncor’s regulatory capital structure, as determined by the PUCT, will be at or below the assumed debt-to-equity ratio established periodically by the PUCT for ratemaking purposes, which is currently set at 60% debt to 40% equity. (See Note 8 to Financial Statements.)

In January 2009, the PUCT awarded certain CREZ construction projects to Oncor. See discussion below under “Regulatory Matters – Oncor Matters with the PUCT.” As a result of the increased capital expenditures for CREZ and the debt-to-equity ratio cap, we expect our distributions from Oncor will be substantially reduced or temporarily discontinued during the CREZ construction period, which is expected to be completed in 2013.

Financial Covenants, Credit Rating Provisions and Cross Default Provisions — The terms of certain of our financing arrangements contain maintenance covenants with respect to leverage ratios and/or minimum net worth. As of March 31, 2011, we were in compliance with all such covenants.

Covenants and Restrictions under Financing Arrangements — Each of the TCEH Senior Secured Facilities and the indentures governing substantially all of the debt we have issued in connection with, and subsequent to, the Merger contain covenants that could have a material impact on our liquidity and operations.

Adjusted EBITDA (as used in the restricted payments covenant contained in the indenture governing the EFH Corp. Senior Secured Notes) for the twelve months ended March 31, 2011 totaled $5.130 billion for EFH Corp. See Exhibits 99(b), 99(c) and 99(d) for a reconciliation of net income (loss) to Adjusted EBITDA for EFH Corp., TCEH and EFIH, respectively, for the three and twelve months ended March 31, 2011 and 2010.

The table below summarizes TCEH’s secured debt to Adjusted EBITDA ratio under the maintenance covenant in the TCEH Senior Secured Facilities and various other financial ratios of EFH Corp., EFIH and TCEH that are applicable under certain other threshold covenants in the TCEH Senior Secured Facilities and the indentures governing the TCEH Senior Notes, the TCEH Senior Secured Second Lien Notes, the EFH Corp. Senior Notes, the EFH Corp. Senior Secured Notes and the EFIH Notes as of March 31, 2011 and December 31, 2010. The debt incurrence and restricted payments/limitations on investments covenants thresholds described below represent levels that must be met in order for EFH Corp., EFIH or TCEH to incur certain permitted debt or make certain restricted payments and/or investments. EFH Corp. and its consolidated subsidiaries are in compliance with their maintenance covenants.

Material Credit Rating Covenants and Credit Worthiness Effects on Liquidity — As a result of TCEH’s non-investment grade credit rating and considering collateral thresholds of certain retail and wholesale commodity contracts, as of March 31, 2011, counterparties to those contracts could have required TCEH to post up to an aggregate of $27 million in additional collateral. This amount largely represents the below market terms of these contracts as of March 31, 2011; thus, this amount will vary depending on the value of these contracts on any given day.

Certain transmission and distribution utilities in Texas have tariffs in place to assure adequate credit worthiness of any REP to support the REP’s obligation to collect securitization bond-related (transition) charges on behalf of the utility. Under these tariffs, as a result of TCEH’s below investment grade credit rating, TCEH is required to post collateral support in an amount equal to estimated transition charges over specified time periods. The amount of collateral support required to be posted, as well as the time period of transition charges covered, varies by utility. As of March 31, 2011, TCEH has posted collateral support in the form of letters of credit to the applicable utilities in an aggregate amount equal to $27 million, with $14 million of this amount posted for the benefit of Oncor.

The PUCT has rules in place to assure adequate credit worthiness of each REP, including the ability to return customer deposits, if necessary. Under these rules, as of March 31, 2011, TCEH posted letters of credit in the amount of $73 million, which are subject to adjustments.

The RRC has rules in place to assure adequate credit worthiness of parties that have mining reclamation obligations. Under these rules, should the RRC determine that the credit worthiness of Luminant Generation Company LLC (a subsidiary of TCEH) is not sufficient to support its reclamation obligations, TCEH may be required to post cash or letter of credit collateral support in an amount currently estimated to be approximately $650 million to $900 million. The actual amount (if required) could vary depending upon numerous factors, including Luminant Generation Company LLC’s credit worthiness and the level of mining reclamation obligations.

ERCOT has rules in place to assure adequate credit worthiness of parties that participate in the “day-ahead” and “real-time markets” operated by ERCOT. Under these rules, TCEH has posted collateral support, predominantly in the form of letters of credit, totaling $240 million as of March 31, 2011 (which is subject to weekly adjustments based on settlement activity with ERCOT).

Other arrangements of EFH Corp. and its subsidiaries, including Oncor’s credit facility, the accounts receivable securitization program (see Note 5 to Financial Statements) and certain leases, contain terms pursuant to which the interest rates charged under the agreements may be adjusted depending on the relevant credit ratings.

In the event that any or all of the additional collateral requirements discussed above are triggered, we believe we will have adequate liquidity to satisfy such requirements.

Material Cross Default Provisions — Certain financing arrangements contain provisions that may result in an event of default if there were a failure under other financing arrangements to meet payment terms or to observe other covenants that could or does result in an acceleration of payments due. Such provisions are referred to as “cross default” provisions.

A default by TCEH or any of its restricted subsidiaries in respect of indebtedness, excluding indebtedness relating to the accounts receivable securitization program, in an aggregate amount in excess of $200 million may result in a cross default under the TCEH Senior Secured Facilities. Under these facilities, such a default will allow the lenders to accelerate the maturity of outstanding balances ($20.9 billion as of April 19, 2011) under such facilities.

The indentures governing the TCEH Senior Notes, TCEH Senior Secured Notes and the TCEH Senior Secured Second Lien Notes contain a cross acceleration provision where a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of TCEH or any of its restricted subsidiaries in an aggregate amount equal to or greater than $250 million may cause the acceleration of the TCEH Senior Notes, TCEH Senior Secured Notes and TCEH Senior Secured Second Lien Notes.

Under the terms of a TCEH rail car lease, which had $44 million in remaining lease payments as of March 31, 2011 and terminates in 2017, if TCEH failed to perform under agreements causing its indebtedness in aggregate principal amount of $100 million or more to become accelerated, the lessor could, among other remedies, terminate the lease and effectively accelerate the payment of any remaining lease payments due under the lease.

Under the terms of another TCEH rail car lease, which had $49 million in remaining lease payments as of March 31, 2011 and terminates in 2028, if obligations of TCEH in excess of $200 million in the aggregate for payments of obligations to third party creditors under lease agreements, deferred purchase agreements or loan or credit agreements are accelerated prior to their original stated maturity, the lessor could, among other remedies, terminate the lease and effectively accelerate the payment of any remaining lease payments due under the lease.

The indentures governing the EFH Corp. Senior Secured Notes contain a cross acceleration provision whereby a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of EFH Corp. or any of its restricted subsidiaries in an aggregate amount equal to or greater than $250 million may cause the acceleration of the EFH Corp. Senior Secured Notes.

The indentures governing the EFIH Notes contain a cross acceleration provision whereby a payment default at maturity or on acceleration of principal indebtedness under any instrument or instruments of EFIH or any of its restricted subsidiaries in an aggregate amount equal to or greater than $250 million may cause the acceleration of the EFIH Notes.

The accounts receivable securitization program contains a cross default provision with a threshold of $200 million that applies in the aggregate to the originator, any parent guarantor of an originator or any subsidiary acting as collection agent under the program. TXU Receivables Company and EFH Corporate Services Company (a direct subsidiary of EFH Corp.), as collection agent, in the aggregate have a cross default threshold of $50,000. If any of the aforementioned defaults on indebtedness of the applicable threshold were to occur, the program could terminate.

We enter into energy-related and financial contracts, the master forms of which contain provisions whereby an event of default or acceleration of settlement would occur if we were to default under an obligation in respect of borrowings in excess of thresholds, which vary, stated in the contracts. The subsidiaries whose default would trigger cross default vary depending on the contract.

Each of TCEH’s natural gas hedging agreements and interest rate swap agreements that are secured with a lien on its assets on a pari passu basis with the TCEH Senior Secured Facilities contains a cross default provision. In the event of a default by TCEH or any of its subsidiaries relating to indebtedness (such amounts varying by contract but ranging from $200 million to $250 million) that results in the acceleration of such debt, then each counterparty under these hedging agreements would have the right to terminate its hedge or interest rate swap agreement with TCEH and require all outstanding obligations under such agreement to be settled.

Other arrangements, including leases, have cross default provisions, the triggering of which would not be expected to result in a significant effect on liquidity.

Guarantees — See Note 7 to Financial Statements for details of guarantees.

See Notes 3 and 7 to Financial Statements regarding VIEs and guarantees, respectively.

See Note 7 to Financial Statements for discussion of commitments and contingencies.

There have been no recently issued accounting standards effective after March 31, 2011 that are expected to materially impact us.

PURA, the PUCT, the RRC, ERCOT, the TCEQ and the Texas Office of Public Utility Counsel (OPUC) are subject to “sunset” review by the Texas Legislature in the 2011 legislative session. Sunset review includes, generally, a comprehensive review of the need for and effectiveness of an administrative agency (the PUCT, the RRC, ERCOT, the TCEQ or the OPUC), along with an evaluation of the advisability of any changes to that agency’s authorizing legislation (e.g. PURA). In 2010, the Texas Sunset Advisory Commission adopted various recommendations regarding these agencies and submitted its recommendations for the Texas Legislature’s consideration during the session, which began in January 2011. We cannot predict the outcome of the sunset review process.

Rate Cases — In January 2011, Oncor filed for a rate review (PUCT Docket No. 38929) with the PUCT and 203 cities based on a test year ended June 30, 2010. If approved as requested, this review would have resulted in an aggregate annual rate increase of approximately $353 million over the test year period adjusted for the impact of weather. Oncor also requested a revised regulatory capital structure of 55% debt to 45% equity. The PUCT, with Oncor’s input and that of the cities and other participating parties, established a procedural schedule for the review. In April 2011, Oncor filed, and the administrative law judges in the rate review granted, a motion requesting abatement of the procedural schedule in the rate review on the grounds that Oncor and the parties to the rate review had reached a Memorandum of Settlement that would settle and resolve all issues in the rate review. Oncor expects to file a stipulation in late April or early May 2011 that incorporates the Memorandum of Settlement along with proposed tariffs. The stipulation and related tariffs must be approved by the PUCT. The terms of the settlement include an approximate $137 million base rate increase and additional provisions to address franchise fees and other expenses. The settlement would result in an impact of less than 1% on an average residential monthly bill of 1,300 kWh for a TXU Energy customer. Approximately $93 million of the increase would become effective by July 1, 2011, and the remainder would become effective by January 1, 2012. The settlement does not change Oncor’s authorized regulatory capital structure of 60% debt and 40% equity or its authorized return on equity of 10.25%.

In August 2009, the PUCT issued a final order with respect to Oncor’s June 2008 rate review filing (PUCT Docket 35717), and new rates were implemented in September 2009. Oncor and four other parties appealed various portions of the rate case final order to a state district court. In January 2011, the District Court signed its judgment reversing the PUCT with respect to two issues: the PUCT’s disallowance of certain franchise fees, and the PUCT’s decision that PURA no longer requires imposition of a rate discount for state colleges and universities. Oncor filed an appeal with the Austin Court of Appeals in February 2011 with respect to the issues it appealed to the District Court and did not prevail upon, as well as the District Court’s decision to reverse the PUCT with respect to discounts for state colleges and universities. Oncor is unable to predict the outcome of the appeal.

Stipulation Approved by the PUCT — In April 2008, the PUCT entered an order (PUCT Docket No. 34077), which became final in June 2008, approving the terms of a stipulation relating to the filing in 2007 by Oncor and Texas Holdings with the PUCT pursuant to Section 14.101(b) of PURA and PUCT Substantive Rule 25.75. The filing reported an ownership change involving Texas Holdings’ purchase of EFH Corp. Among other things, the stipulation required the filing of a rate case by Oncor no later than July 1, 2008 based on a test year ended December 31, 2007, which Oncor filed in June 2008 as discussed above. In July 2008, Nucor Steel filed an appeal of the PUCT’s order in the 200^th District Court of Travis County, Texas. A hearing on the appeal was held in June 2010, and the District Court affirmed the PUCT order in its entirety. Nucor Steel appealed that ruling to the Third District Court of Appeals in Austin, Texas in July 2010. Oral argument was held before the court in March 2011. There is no deadline for the court to act. While Oncor is unable to predict the outcome of the appeal, it does not expect the appeal to affect the major provisions of the stipulation.

Competitive Renewable Energy Zones (CREZs) — In January 2009, the PUCT awarded Oncor 17 CREZ construction projects (PUCT Docket Nos. 35665 and 37902) requiring 14 related Certificate of Convenience and Necessity (CCN) amendment proceedings before the PUCT. As of March 31, 2011, all 17 projects and 14 CCN amendments have been approved by the PUCT. The projects involve the construction of transmission lines and stations to support the transmission of electricity from renewable energy sources, principally wind generation facilities, in west Texas to population centers in the eastern part of Texas. In addition to these projects, ERCOT completed a study in December 2010 that will result in Oncor and other transmission service providers building additional facilities to provide further voltage support to the transmission grid as a result of CREZ. Oncor currently estimates, based on these additional voltage support facilities and the approved routes and stations for its awarded CREZ projects, that CREZ construction costs will total approximately $2.0 billion. CREZ-related costs could change based on finalization of costs for the additional voltage support facilities and final detailed designs of subsequent project routes. As of March 31, 2011, Oncor’s cumulative CREZ-related capital expenditures totaled $417 million, including $101 million during the three months ended March 31, 2011. Oncor expects that all necessary permitting actions and other requirements and all construction activities for Oncor’s CREZ construction projects will be completed by the end of 2013.

Transmission Cost Recovery and Rates (PUCT Docket No. 38938) — In order to recover increases in its transmission costs, including incremental fees paid to other transmission service providers due to an increase in their rates, Oncor is allowed to request an update twice a year to the transmission cost recovery factor (TCRF) component of its retail delivery rates charged to REPs. In December 2010, an application was filed to increase the TCRF, which was administratively approved in January 2011 and became effective March 1, 2011. This application increased Oncor’s annualized revenues by an estimated $33 million.

Remand of 1999 Wholesale Transmission Matrix Case (PUCT Docket No. 38780) — In October 2010, the PUCT established Docket No. 38780 for the remand of Docket No. 20381, the 1999 wholesale transmission charge matrix case. A joint settlement agreement was entered into effective October 6, 2003. This settlement resolves disputes regarding wholesale transmission pricing and charges for the period of January 1997 through August 1999, the period prior to the September 1, 1999 effective date of the legislation that authorized 100% postage stamp pricing for ERCOT wholesale transmission. Since a series of appeals has become final, the 1999 matrix docket has been remanded to the PUCT to address additional issues. If the appealing parties prevail and the PUCT rules adversely with respect to these issues, Oncor could be subject to liabilities totaling up to approximately $22 million. At this time, Oncor cannot predict the outcome of these matters.

Mine Safety Disclosures — Required by the Dodd-Frank Wall Street Reform and Consumer Protection Act

Safety is a top priority in all our businesses, and accordingly, it is a key component of our focus on operational excellence, our employee performance reviews and employee compensation. Our health and safety program objectives are to prevent workplace accidents and ensure that all employees return home safely and comply with all regulations.

We currently own and operate 12 surface lignite coal mines in Texas to provide fuel for our electricity generation facilities. These mining operations are regulated by the US Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977, as amended (the Mine Act) as well as other regulatory agencies such as the RRC. The MSHA inspects US mines, including ours, on a regular basis and if it believes a violation of the Mine Act or any health or safety standard or other regulation has occurred, it may issue a citation or order, generally accompanied by a proposed fine or assessment. Such citations and orders can be contested and appealed to the Federal Mine Safety and Health Review Commission (FMSHRC), which often results in a reduction of the severity and amount of fines and assessments and sometimes results in dismissal. The number of citations, orders and proposed assessments vary depending on the size of the mine as well as other factors.

Disclosures related to specific mines pursuant to Section 1503 of the recently enacted Dodd-Frank Wall Street Reform and Consumer Protection Act sourced from data documented as of April 11, 2011 in the MSHA Data Retrieval System for the three months ended March 31, 2011 (except pending legal actions, which are as of March 31, 2011), are as follows:

During the three months ended March 31, 2011, our mining operations received one citation and order under Section 104(d) (Kosse mine), no citations, orders or written notices under Sections 104(b), 104(e), 107(a) or 110(b)(2) of the Mine Act, and they experienced no fatalities.

We cannot predict future regulatory or legislative actions or any changes in economic and securities market conditions. Such actions or changes could significantly alter our basic financial position, results of operations or cash flows.

Market risk is the risk that we may experience a loss in value as a result of changes in market conditions affecting factors, such as commodity prices and interest rates that may be experienced in the ordinary course of business. Our exposure to market risk is affected by a number of factors, including the size, duration and composition of our energy and financial portfolio, as well as the volatility and liquidity of markets. Instruments used to manage this exposure include interest rate swaps to manage interest rate risk related to debt, as well as exchange traded, over-the-counter contracts and other contractual arrangements to manage commodity price risk.

We manage the commodity price, counterparty credit and commodity-related operational risk related to the unregulated energy business within limitations established by senior management and in accordance with overall risk management policies. Interest rate risk is managed centrally by the corporate treasury function. Market risks are monitored by risk management groups that operate independently of the wholesale commercial operations, utilizing defined practices and analytical methodologies. These techniques measure the risk of change in value of the portfolio of contracts and the hypothetical effect on this value from changes in market conditions and include, but are not limited to, Value at Risk (VaR) methodologies. Key risk control activities include, but are not limited to, transaction review and approval (including credit review), operational and market risk measurement, validation of transaction capture, portfolio valuation and reporting, including mark-to-market valuation, VaR and other risk measurement metrics.

We have a corporate risk management organization that is headed by the Chief Financial Officer, who also functions as the Chief Risk Officer. The Chief Risk Officer, through his designees, enforces applicable risk limits, including the respective policies and procedures to ensure compliance with such limits and evaluates the risks inherent in our businesses.

The competitive business is subject to the inherent risks of market fluctuations in the price of electricity, natural gas and other energy-related products it markets or purchases. We actively manage the portfolio of owned generation assets, fuel supply and retail sales load to mitigate the near-term impacts of these risks on results of operations. Similar to other participants in the market, we cannot fully manage the long-term value impact of structural declines or increases in natural gas and power prices and spark spreads (differences between the market price of electricity and its cost of production).

In managing energy price risk, we enter into a variety of market transactions including, but not limited to, short- and long-term contracts for physical delivery, exchange traded and over-the-counter financial contracts and bilateral contracts with customers. Activities include hedging, the structuring of long-term contractual arrangements and proprietary trading. We continuously monitor the valuation of identified risks and adjust positions based on current market conditions. We strive to use consistent assumptions regarding forward market price curves in evaluating and recording the effects of commodity price risk.

Long-Term Hedging Program — See “Significant Activities and Events” above for a description of the program, including potential effects on reported results.

VaR Methodology — A VaR methodology is used to measure the amount of market risk that exists within the portfolio under a variety of market conditions. The resultant VaR produces an estimate of a portfolio’s potential for loss given a specified confidence level and considers, among other things, market movements utilizing standard statistical techniques given historical and projected market prices and volatilities.

A Monte Carlo simulation methodology is used to calculate VaR and is considered by management to be the most effective way to estimate changes in a portfolio’s value based on assumed market conditions for liquid markets. The use of this method requires a number of key assumptions, such as use of (i) an assumed confidence level; (ii) an assumed holding period (i.e., the time necessary for management action, such as to liquidate positions); and (iii) historical estimates of volatility and correlation data.

Trading VaR — This measurement estimates the potential loss in fair value, due to changes in market conditions, of all contracts entered into for trading purposes based on a 95% confidence level and an assumed holding period of five to 60 days.

VaR for Energy-Related Contracts Subject to Mark-to-Market (MtM) Accounting — This measurement estimates the potential loss in fair value, due to changes in market conditions, of all contracts marked-to-market in net income (principally hedges not accounted for as cash flow hedges and trading positions), based on a 95% confidence level and an assumed holding period of five to 60 days.

Earnings at Risk (EaR) — This measurement estimates the potential reduction of pretax earnings for the periods presented, due to changes in market conditions, of all energy-related contracts marked-to-market in net income and contracts not marked-to-market in net income that are expected to be settled within the fiscal year (physical purchases and sales of commodities). Transactions accounted for as cash flow hedges are also included for this measurement. A 95% confidence level and a five to 60 day holding period are assumed in determining EaR.

The decreases in the risk measures (MtM VaR and EaR) above primarily reflected a reduction of positions in the long-term hedging program due to maturities.

As of March 31, 2011, the potential reduction of annual pretax earnings due to a one percentage-point (100 basis points) increase in floating interest rates on long-term debt totaled $24 million, taking into account the interest rate swaps discussed in Note 6 to Financial Statements.

Credit risk relates to the risk of loss associated with nonperformance by counterparties. We maintain credit risk policies with regard to our counterparties to minimize overall credit risk. These policies prescribe practices for evaluating a potential counterparty’s financial condition, credit rating and other quantitative and qualitative credit criteria and specify authorized risk mitigation tools including, but not limited to, use of standardized master netting contracts and agreements that allow for netting of positive and negative exposures associated with a single counterparty. We have processes for monitoring and managing credit exposure of our businesses including methodologies to analyze counterparties’ financial strength, measurement of current and potential future exposures and contract language that provides rights for netting and set-off. Credit enhancements such as parental guarantees, letters of credit, surety bonds and margin deposits are also utilized. Additionally, individual counterparties and credit portfolios are managed to assess overall credit exposure. This evaluation results in establishing exposure limits or collateral requirements for entering into an agreement with a counterparty that creates exposure. Additionally, we have established controls to determine and monitor the appropriateness of these limits on an ongoing basis. Prospective material adverse changes in the payment history or financial condition of a counterparty or downgrade of its credit quality result in the reassessment of the credit limit with that counterparty. This process can result in the subsequent reduction of the credit limit or a request for additional financial assurances.

Credit Exposure — Our gross exposure to credit risk associated with trade accounts receivable (retail and wholesale) and net asset positions (before credit collateral) arising from commodity contracts and hedging and trading activities totaled $2.499 billion as of March 31, 2011. The components of this exposure are discussed in more detail below.

Assets subject to credit risk as of March 31, 2011 include $517 million in retail trade accounts receivable before taking into account cash deposits held as collateral for these receivables totaling $75 million. The risk of material loss (after consideration of bad debt allowances) from nonperformance by these customers is unlikely based upon historical experience. Allowances for uncollectible accounts receivable are established for the potential loss from nonpayment by these customers based on historical experience, market or operational conditions and changes in the financial condition of large business customers.

The remaining credit exposure arises from wholesale trade receivables, commodity contracts and hedging and trading activities, including interest rate hedging. Counterparties to these transactions include energy companies, financial institutions, electric utilities, independent power producers, oil and gas producers, local distribution companies and energy trading and marketing companies. As of March 31, 2011, the exposure to credit risk from these counterparties totaled $1.982 billion taking into account the standardized master netting contracts and agreements described above but before taking into account $684 million in credit collateral (cash, letters of credit and other credit support). The net exposure (after credit collateral) of $1.298 billion decreased $308 million in the three months ended March 31, 2011, reflecting a reduction of positions in the long-term hedging program due to maturities and the effect of an increase in forward natural gas prices on the value of positions in the program.

Of this $1.298 billion net exposure, essentially all is with investment grade customers and counterparties, as determined using publicly available information including major rating agencies’ published ratings and our internal credit evaluation process. Those customers and counterparties without a S&P rating of at least BBB- or similar rating from another major rating agency are rated using internal credit methodologies and credit scoring models to estimate a S&P equivalent rating. The company routinely monitors and manages credit exposure to these customers and counterparties on this basis.

The following table presents the distribution of credit exposure as of March 31, 2011 arising from wholesale trade receivables, commodity contracts and hedging and trading activities. This credit exposure represents wholesale trade accounts receivable and net asset positions on the balance sheet arising from hedging and trading activities after taking into consideration netting provisions within each contract, setoff provisions in the event of default and any master netting contracts with counterparties. See Note 11 to Financial Statements for further discussion of portions of this exposure related to activities marked-to-market in the financial statements.

In addition to the exposures in the table above, contracts classified as “normal” purchase or sale and non-derivative contractual commitments are not marked-to-market in the financial statements. Such contractual commitments may contain pricing that is favorable considering current market conditions and therefore represent economic risk if the counterparties do not perform. Nonperformance could have a material adverse impact on future results of operations, financial condition and cash flows.

Significant (10% or greater) concentration of credit exposure exists with three counterparties, which represented 41%, 33% and 14% of the net $1.298 billion exposure. We view exposure to these counterparties to be within an acceptable level of risk tolerance due to the applicable counterparty’s credit rating and the importance of our business relationship with the counterparty. However, this concentration increases the risk that a default would have a material effect on results of operations.

With respect to credit risk related to the long-term hedging program, essentially all of the transaction volumes are with counterparties with an A credit rating or better. However, there is current and potential credit concentration risk related to the limited number of counterparties that comprise the substantial majority of the program with such counterparties being in the banking and financial sector. The transactions with these counterparties contain certain credit rating provisions that would require the counterparties to post collateral in the event of a material downgrade in the credit rating of the counterparties. An event of default by one or more hedge counterparties could subsequently result in termination-related settlement payments that reduce available liquidity if amounts are owed to the counterparties related to the commodity contracts or delays in receipts of expected settlements if the hedge counterparties owe amounts to us. While the potential concentration of risk with these counterparties is viewed to be within an acceptable risk tolerance, the exposure to hedge counterparties is managed through the various ongoing risk management measures described above.

This report and other presentations made by us contain “forward-looking statements.” All statements, other than statements of historical facts, that are included in this report, or made in presentations, in response to questions or otherwise, that address activities, events or developments that we expect or anticipate to occur in the future, including such matters as projections, capital allocation, future capital expenditures, business strategy, competitive strengths, goals, future acquisitions or dispositions, development or operation of power generation assets, market and industry developments and the growth of our businesses and operations (often, but not always, through the use of words or phrases such as “intends,” “plans,” “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimated,” “should,” “projection,” “target,” “goal,” “objective” and “outlook”), are forward-looking statements. Although we believe that in making any such forward-looking statement our expectations are based on reasonable assumptions, any such forward-looking statement involves uncertainties and is qualified in its entirety by reference to the discussion of risk factors under Item 1A, “Risk Factors” in this report and the 2010 Form 10-K and the discussion under Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this report and the following important factors, among others, that could cause our actual results to differ materially from those projected in such forward-looking statements:

Any forward-looking statement speaks only as of the date on which it is made, and except as may be required by law, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of them; nor can we assess the impact of each such factor or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. As such, you should not unduly rely on such forward-looking statements.

The industry and market data and other statistical information used throughout this report are based on independent industry publications, government publications, reports by market research firms or other published independent sources, including certain data published by ERCOT, the PUCT and NYMEX. We did not commission any of these publications or reports. Some data is also based on good faith estimates, which are derived from our review of internal surveys, as well as the independent sources listed above. Independent industry publications and surveys generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. While we believe that each of these studies and publications is reliable, we have not independently verified such data and make no representation as to the accuracy of such information. Forecasts are particularly likely to be inaccurate, especially over long periods of time, and we do not know what assumptions regarding general economic growth are used in preparing the forecasts included in this report. Similarly, while we believe that such internal and external research is reliable, it has not been verified by any independent sources, and we make no assurances that the predictions contained therein are accurate.

An evaluation was performed under the supervision and with the participation of our management, including the principal executive officer and principal financial officer, of the effectiveness of the design and operation of the disclosure controls and procedures in effect as of the end of the current period included in this quarterly report. Based on the evaluation performed, our management, including the principal executive officer and principal financial officer, concluded that the disclosure controls and procedures were effective. During the most recent fiscal quarter covered by this quarterly report, there has been no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

On April 25, 2011, EFIH and EFIH Finance (collectively with EFIH, the Issuer) completed a private exchange transaction (Exchange) pursuant to Exchange Agreements (Exchange Agreements) among the Issuer and certain funds and accounts managed by institutional investors (collectively, the Exchange Holders). Pursuant to the Exchange Agreements, the Issuer issued $406,392,000 aggregate principal amount of its 11% Senior Secured Second Lien Notes due 2021 (New Notes) in exchange for the surrender by the Exchange Holders of $228,974,469 aggregate principal amount of EFH Corp. 11.250%/12.000% Senior Toggle Notes due 2017, $162,596,000 aggregate principal amount of EFH Corp. 10.875% Senior Notes due 2017, and $36,226,000 aggregate principal amount of EFH Corp. 5.55% Series P Senior Notes due November 15, 2014 (collectively, the Old Notes). The Old Notes have been deposited in a custody account of EFIH and remain outstanding.

On April 25, 2011, the Issuer entered into an indenture (Indenture) among the Issuer and The Bank of New York Mellon Trust Company, N.A., as trustee. Pursuant to the Indenture, the Issuer issued $406,392,000 aggregate principal amount of New Notes. The New Notes will mature on October 1, 2021. Interest on the New Notes is payable in cash semiannually in arrears on May 15 and November 15 of each year at a fixed rate of 11% per annum, and the first interest payment is due on November 15, 2011.

The New Notes are secured, on a second-priority basis, by the pledge of all membership interests and other investments EFIH owns or holds in Oncor Holdings or any of Oncor Holdings’ subsidiaries (such membership interests and other investments, the “Collateral”).

The New Notes are senior obligations of the Issuer and rank equally in right of payment with all senior indebtedness of the Issuer. The New Notes will be effectively senior to all unsecured indebtedness of the Issuer, to the extent of the value of the Collateral, and will be effectively subordinated to indebtedness of the Issuer that is either (1) secured by a lien on the Collateral that is senior to the second-priority liens securing the New Notes or (2) secured by assets of EFIH other than the Collateral, to the extent of the value of the assets securing such indebtedness. Furthermore, the New Notes will be structurally subordinated to all indebtedness and other liabilities of EFIH’s subsidiaries (other than EFIH Finance), including Oncor Holdings and its subsidiaries, any of EFIH’s future foreign subsidiaries and any other unrestricted subsidiaries and senior in right of payment to any future subordinated indebtedness of the Issuer.

The New Notes and the Indenture restrict the Issuer’s and their respective restricted subsidiaries’ ability to, among other things, make restricted payments, incur debt and issue preferred stock, incur liens, permit dividend and other payment restrictions on restricted subsidiaries, merge, consolidate or sell assets and engage in transactions with affiliates. These covenants are subject to a number of important additional limitations and exceptions. The New Notes and the Indenture also contain customary events of default, including, among others, failure to pay principal or interest on the New Notes when due. If an event of default occurs under the New Notes and the Indenture, the trustee or the holders of at least 30% in principal amount outstanding of the New Notes may declare the principal amount on the New Notes to be due and payable immediately. There will initially be no restricted subsidiaries under the Indenture (other than EFIH Finance, which has no assets). Oncor Holdings, the immediate parent of Oncor, and its subsidiaries are unrestricted subsidiaries under the Indenture and, accordingly, are not subject to any of the restrictive covenants in the Indenture.

The Issuer may redeem the New Notes, in whole or in part, at any time on or after May 15, 2016, at specified redemption prices, plus accrued and unpaid interest, if any. In addition, before May 15, 2014, the Issuer may redeem up to 35% of the aggregate principal amount of the New Notes from time to time at a redemption price of 111% of the aggregate principal amount of the New Notes, plus accrued and unpaid interest, if any, with the net cash proceeds of certain equity offerings. The Issuer may also redeem the New Notes at any time prior to May 15, 2016 at a price equal to 100% of their principal amount, plus accrued and unpaid interest and a “make-whole” premium. Upon the occurrence of a change in control, the Issuer must offer to repurchase the New Notes at 101% of their principal amount, plus accrued and unpaid interest, if any.

The New Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States without registration or an applicable exemption from the Securities Act.

A copy of the Indenture is filed as Exhibit 4(e) to this Form 10Q and is incorporated herein by reference. The above description of the Indenture is qualified in its entirety by reference to the attached Indenture.

On April 25, 2011, the Issuer also entered into a registration rights agreement (Registration Rights Agreement) with the Exchange Holders. Pursuant to the Registration Rights Agreement, the Issuer has agreed to use its commercially reasonable efforts to register with the SEC notes having substantially identical terms as the New Notes (except for provisions relating to the transfer restrictions and payment of additional interest) as part of an offer to exchange such registered notes for the New Notes; provided that such exchange offer registration statement need not be filed (or declared effective) if the New Notes held by holders eligible to participate in any such exchange offer (a) become freely transferable by such holders pursuant to Rule 144 under the Securities Act or any successor provision thereto or otherwise where no conditions of Rule 144 are then applicable (other than the holding period requirement in paragraph (d)(1)(ii) of Rule 144 so long as such holding period requirement is satisfied and other than the current reporting requirement of Rule 144(c) so long as such reporting requirement is satisfied), (b) do not bear any restrictive legends and (c) do not bear a restrictive CUSIP number. If the exchange offer registration statement has not been filed and declared effective within 365 days after the original issue date of the New Notes (if the Issuer is then required to make an exchange offer) or such registration statement ceases to be effective at any time during the prescribed registration period (subject to certain exceptions) (a Registration Default), the annual interest rate on the New Notes will increase by 25 basis points for the first 90-day period during which a Registration Default continues, and thereafter the annual interest rate on the Notes will increase by 50 basis points over the original interest rate for the remaining period during which the Registration Default continues. If the Registration Default is corrected, the applicable interest rate on such notes will revert to the original level.

In connection with the issuance of the New Notes, EFIH entered into a junior lien pledge agreement (the Junior Lien Pledge Agreement), dated as of April 25, 2011, to reflect the pledge by EFIH of the Collateral in favor of The Bank of New York Mellon Trust Company, N.A., in its capacity as collateral agent, for the benefit of the holders of the New Notes.

A copy of the Junior Lien Pledge Agreement is filed as Exhibit 4(f) to this Form 10Q and is incorporated herein by reference. The above description of the Junior Lien Pledge Agreement is qualified in its entirety by reference to the attached Junior Lien Pledge Agreement.

On April 27, 2011, to reward Paul M. Keglevic, Executive Vice President and Chief Financial Officer of EFH Corp., for his performance in connection with the company’s liability management program, the Organization and Compensation Committee of the Board of Directors of EFH Corp. approved a discretionary cash bonus to Mr. Keglevic in the amount of $1,000,000, half of which will be paid in May 2011 and half of which will be paid in September 2012, provided that Mr. Keglevic remains employed by the Company at that time. The Committee also approved a discretionary cash bonus to M. A. McFarland, Executive Vice President of EFH Corp., in the amount of $350,000 in recognition of his performance in connection with the liability management program.

Reference is made to the discussion in Note 7 to Financial Statements regarding legal proceedings.

There have been no material changes from the risk factors disclosed under the heading “Risk Factors” in Item 1A of the 2010 Form 10-K except for the risk factors discussed below and the information disclosed elsewhere in this Form 10-Q that provides factual updates to risk factors contained in the 2010 Form 10-K.

Lenders and holders of our debt have in the past alleged and might allege in the future that we are not operating in compliance with covenants in our debt agreements, which, even if the claims have no merit, could cause the trading price of our debt securities to decline.

Given our financial condition, lenders or holders of our debt might assert at any time that we are not operating in compliance with covenants in our debt agreements or make other related allegations, including for the purpose of attempting to accelerate the maturity of such debt and/or attempting to obtain economic benefits from us. Even if any claim by lenders or holders of our debt alleging noncompliance or an event of default under our debt agreements is without merit, such a claim could nevertheless cause the trading price of the debt to decline.

We may not be able to repay or refinance our debt as or before it becomes due, or obtain additional financing, particularly if forward natural gas prices do not significantly increase.

We may not be able to repay or refinance our debt obligations as or before they become due, or we may be able to refinance such amounts only on terms that will increase our cost of borrowing or on terms that may be more onerous. Our ability to successfully implement any future refinancing of our debt will depend, among other things, on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control, including, without limitation, wholesale electricity prices in ERCOT (which are primarily driven by the price of natural gas and ERCOT market heat rates) and general conditions in the credit markets. Refinancing may also be difficult because of the slow economic recovery, the possibility of rising interest rates and the impending surge of large debt maturities of other borrowers. Due to our below investment grade credit ratings, we may be more heavily exposed to these refinancing risks than other borrowers.

The amount of non-extended commitments under the TCEH Revolving Credit Facility (approximately $640 million) will mature in October 2013, approximately $3.8 billion aggregate principal amount of non-extended term and deposit letter of credit loans under the TCEH Senior Secured Facilities will mature in October 2014, the extended revolving commitments under the TCEH Revolving Credit Facility (approximately $1.4 billion) will mature in October 2016 and approximately $16.4 billion aggregate principal amount of extended term loans and extended letter of credit loans under the TCEH Senior Secured Facilities will mature in October 2017. The extended loans under the TCEH Senior Secured Facilities include a “springing maturity” provision pursuant to which (a) in the event that $500 million aggregate principal amount of the TCEH Senior Notes due in 2015 (other than notes held by EFH Corp. or its controlled affiliates as of March 31, 2011 to the extent held as of the date of determination) or more than $150 million aggregate principal amount of the TCEH Senior Notes due in 2016 (other than notes held by EFH Corp. or its controlled affiliates as of March 31, 2011 to the extent held as of the date of determination), as applicable, remain outstanding as of 91 days prior to the maturity date of the applicable notes and (b) TCEH’s Consolidated Total Debt to Consolidated EBITDA Ratio (as such term is defined in the TCEH Senior Secured Facilities) is greater than 6.00 to 1.00 at such applicable determination date, then the maturity date of the extended loans will automatically change to 90 days prior to the maturity date of the applicable notes. As of March 31, 2011, there were $3.2 billion aggregate principal amount of TCEH Senior Notes due in 2015 and $1.4 billion aggregate principal amount of TCEH Senior Notes due in 2016. As a result of this “springing maturity” provision, we may lose the benefit of the extension if we are unable to refinance the requisite portion of the TCEH Senior Notes by the applicable deadline. If holders of the TCEH Senior Notes are unwilling to extend the maturities of their notes, then, to avoid the “springing maturity” of the extended loans, we may be required to repay a substantial portion of the TCEH Senior Notes at par. There is no assurance that we will be able to make such payments whether through cash on hand or additional financings.

Wholesale electricity prices in the ERCOT market largely correlate with the price of natural gas. Accordingly, the contribution to earnings and the value of our baseload generation assets are dependent in significant part upon the price of natural gas. Forward natural gas prices have generally trended downward since mid-2008. In recent years, natural gas supply has outpaced demand as a result of increased drilling of shale gas deposits combined with lingering demand weakness associated with the economic recession, and many industry experts expect this supply/demand imbalance to continue for a number of years, thereby depressing natural gas prices for a long-term period. These market conditions are challenging to the long-term profitability of our generation assets. Specifically, low natural gas prices and their correlated effect in ERCOT on wholesale electricity prices could have a material adverse impact on the overall profitability of our generation assets for periods in which we do not have significant hedge positions. As of March 31, 2011, we have hedged approximately 50% and 26% of our wholesale natural gas price exposure related to expected generation output for 2013 and 2014, respectively, and do not have any significant amounts of hedges in place for periods after 2014. A continuation of current forward natural gas prices or a further decline of forward natural gas prices could limit our ability to hedge our wholesale electricity revenues at sufficient price levels to support our interest payments or debt maturities, result in further declines in the values of our baseload generation assets and adversely impact our ability to refinance our debt or obtain additional financing.

In addition, EFH Corp.’s liabilities and those of EFCH exceed our and EFCH’s assets as shown on our and EFCH’s balance sheet prepared in accordance with US GAAP as of March 31, 2011. Our assets include $6.2 billion of goodwill as of March 31, 2011. In the third quarter 2010, we recorded a $4.1 billion noncash goodwill impairment charge reflecting the estimated effect of lower wholesale electricity prices on the enterprise value of TCEH, driven by the sustained decline in forward natural gas prices, as indicated by our cash flow projections and declines in market values of securities of comparable companies. The value of our goodwill will continue to depend on, among other things, wholesale electricity prices in the ERCOT market. Recent valuation analyses of TCEH’s business indicate that the principal amount of its outstanding debt exceeds its enterprise value. We may have difficulty successfully implementing any refinancing of our debt due to our financial position as reflected in our balance sheet and the valuation analyses. Further, a lack of available liquidity could adversely impact the evaluation of our creditworthiness by counterparties and rating agencies. In particular, such concerns by existing and potential counterparties could significantly limit TCEH’s wholesale markets activities, including its long-term hedging program.

Under the terms of the indentures governing the TCEH Senior Notes, Senior Secured Notes and Senior Secured Second Lien Notes and the terms of the TCEH Senior Secured Facilities, TCEH is restricted from making certain payments to EFH Corp.

EFH Corp. is a holding company and substantially all of its reported consolidated assets are held by its subsidiaries. As of March 31, 2011, TCEH and its subsidiaries held approximately 80% of EFH Corp.’s reported consolidated assets and for the three months ended March 31, 2011, TCEH and its subsidiaries represented all of EFH Corp.’s reported consolidated revenues. EFH Corp. may need to borrow money from TCEH from time to time in order to pay its obligations. However, under the terms of the indentures governing the TCEH Senior Notes, Senior Secured Notes and Senior Secured Second Lien Notes and the terms of the TCEH Senior Secured Facilities, TCEH is restricted from making certain payments to EFH Corp., except in the form of certain loans to cover certain of EFH Corp.’s obligations and dividends and distributions in certain other limited circumstances if permitted by applicable state law. Further, the indentures governing the TCEH Senior Notes, Senior Secured Notes and Senior Secured Second Lien Notes and the terms of the TCEH Senior Secured Facilities do not permit such intercompany loans to service EFH Corp. debt unless required for EFH Corp. to pay principal, premium and interest when due on debt incurred by EFH Corp. to finance the Merger or that was in existence prior to the Merger, or any debt incurred by EFH Corp. to replace, refund or refinance such debt. Such loans are also permitted to service other debt, subject to limitations on the amount of the loans. As a result, unless and until the net proceeds from the offering of any notes by EFH Corp. are used to replace, refund or refinance EFH Corp. debt, intercompany loans from TCEH to EFH Corp. to make payments on such notes are restricted. In addition, TCEH is prohibited from making certain loans to EFH Corp. if certain events of default under the indentures governing the TCEH Senior Notes, Senior Secured Notes or Senior Secured Second Lien Notes or the terms of the TCEH Senior Secured Facilities have occurred and are continuing.

In addition, the amendment to the TCEH Senior Secured Facilities that became effective in April 2011 contains certain provisions related to notes receivable from EFH Corp. that are payable to TCEH on demand and arise from cash loaned for (i) debt principal and interest payments (the “P&I Note”) and (ii) other general corporate purposes of EFH Corp. (the “SG&A Note” and, together with the P&I Note, the “Intercompany Notes”). TCEH agreed in the amendment:

Additionally, a lender could attempt to attack the Intercompany Notes by filing a state law cause of action for fraudulent conveyance under principles similar to those permitted under the US Bankruptcy Code. If a lender were to show that the Intercompany Notes from TCEH to EFH Corp. were fraudulent transfers, those loans could be voided and the amount of the loans would be required to be returned to TCEH. If TCEH is not able to continue making intercompany loans to EFH Corp. as a result of the restrictions in the amendment or otherwise, EFH Corp. may not have sufficient cash flows to meet its obligations.

Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01 hereof) conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 1.05.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Issuer, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

Except as described under Article 9 hereof, the Initial Notes offered by the Issuer, any Additional Notes subsequently issued under this Indenture and any other series of debt securities constituting Required Debt under this Indenture shall be treated as a single class for all purposes under this Indenture, including, among other things, waivers, amendments 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. Any Additional Notes shall be issued with the benefit of an indenture supplemental to this Indenture.

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

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. In addition, at any time, and from time to time, the Trustee shall, upon receipt of an Issuer Authentication Order, authenticate and deliver any Additional Notes or Exchange Notes for an aggregate principal amount specified in such Issuer Authentication Order for such Additional Notes or Exchange Notes. Such Issuer Authentication Order shall specify the amount of the Notes to be authenticated and, in the case of any issuance of Additional Notes, shall certify that such issuance is in compliance with Sections 4.09 and 4.12 hereof.

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

The Issuer shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes (“Note Register”) and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without prior notice to any Holder.

The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such Registrar or Paying Agent. The Issuer or any of its Subsidiaries may act as Registrar or Paying Agent.

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

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

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

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

(a) Transfer and Exchange of Global Notes. Except as otherwise set forth in this Section 2.06, a Global Note may be transferred, in whole and not in part, only to another nominee of the Depositary or to a successor Depositary or a nominee of such successor Depositary. A beneficial interest in a Global Note may not be exchanged for a Definitive Note unless (i) the Depositary (x) notifies the

Issuer that it is unwilling or unable to continue as Depositary for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days or (ii) there shall have occurred and be continuing a Default with respect to the Notes. Upon the occurrence of any of the preceding events in (i) or (ii) above, Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the Depositary (in accordance with its customary procedures). Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events in (i) or (ii) above and pursuant to Section 2.06(c) hereof. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); provided, however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f) hereof.

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

Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in a Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person. Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i).

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(i) hereof, the transferor of such beneficial interest must deliver to the Registrar either (A) both (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) both (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note of the same series in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above. Upon consummation of an Exchange Offer by the Issuer in accordance with Section 2.06(f) hereof, the requirements of this Section 2.06(b)(ii) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial

interests in the Restricted Global Notes. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

(iii) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(ii) hereof and the Registrar receives the following:

(A) if the transferee will take delivery in the form of a beneficial interest in a 144A Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; or

(B) if the transferee will take delivery in the form of a beneficial interest in a Regulation S Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof.

A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 2.06(b)(ii) hereof and:

(A) such exchange or transfer is effected pursuant to the Exchange Offer in accordance with the Registration Rights Agreement and the holder of the beneficial interest to be transferred, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable Letter of Transmittal that it is not (1) a broker-dealer, (2) a Person participating in the distribution of the Exchange Notes or (3) a Person who is an affiliate (as defined in Rule 144) of the Issuer;

(B) such transfer is effected pursuant to the Shelf Registration Statement in accordance with the Registration Rights Agreement;

(C) such transfer is effected by a broker-dealer pursuant to the Exchange Registration Statement in accordance with the Registration Rights Agreement; or

and, in each such case set forth in this subparagraph (D), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

If any such transfer is effected pursuant to subsection (B) or (D) above at a time when an Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Issuer Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to subparagraph (B) or (D) above.

Upon such exchange of beneficial interests pursuant to this Section 2.06(b)(iv), the Registrar shall reflect on its books and records the date of such exchange and a decrease and increase in the principal amount of the applicable Restricted Global Note and the Unrestricted Global Note, respectively, equal to the principal amount of beneficial interests exchanged. Following any such exchange pursuant to this Section 2.06(b)(iv) of all of the beneficial interests in a Restricted Global Note to an Unrestricted Global Note, such Restricted Global Note shall be cancelled.

Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

and, in each such case set forth in this subsection (D), if the Registrar so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

Upon satisfaction of the conditions of any of the subparagraphs in this Section 2.06(d)(ii), the Trustee shall cancel the Definitive Notes and increase or cause to be increased the aggregate principal amount of the Unrestricted Global Note.

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

If any such exchange or transfer from a Definitive Note to a beneficial interest is effected pursuant to subsections (ii)(B), (ii)(D) or (iii) above at a time when an Unrestricted Global Note has not yet been issued, the Issuer shall issue and, upon receipt of an Issuer Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal amount of Definitive Notes so transferred.

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

(i) Restricted Definitive Notes to Restricted Definitive Notes. Any Restricted Definitive Note may be transferred to and registered in the name of Persons who take delivery thereof in the form of a Restricted Definitive Note if the Registrar receives the following:

(A) if the transfer will be made to a QIB in accordance with Rule 144A, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof;

(B) if the transfer will be made pursuant to Rule 903 or Rule 904, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof; or

(C) if the transfer will be made pursuant to any other exemption from the registration requirements of the Securities Act, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications required by item (3) thereof, if applicable.

(ii) Restricted Definitive Notes to Unrestricted Definitive Notes. Any Restricted Definitive Note may be exchanged by the Holder thereof for an Unrestricted Definitive Note or transferred to a Person or Persons who take delivery thereof in the form of an Unrestricted Definitive Note if:

(B) any such transfer is effected pursuant to the Shelf Registration Statement in accordance with the Registration Rights Agreement;

(C) any such transfer is effected by a broker-dealer pursuant to the Exchange Registration Statement in accordance with the Registration Rights Agreement; or

(1) if the Holder of such Restricted Definitive Notes proposes to exchange such Notes for an Unrestricted Definitive Note, a certificate from such Holder substantially in the form of Exhibit C hereto, including the certifications in item (1)(d) thereof; or

(2) if the Holder of such Restricted Definitive Notes proposes to transfer such Notes to a Person who shall take delivery thereof in the form of an Unrestricted Definitive Note, a certificate from such Holder substantially in the form of Exhibit B hereto, including the certifications in item (4) thereof;

(iii) Unrestricted Definitive Notes to Unrestricted Definitive Notes. A Holder of Unrestricted Definitive Notes may transfer such Notes to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note. Upon receipt of a request to register such a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the instructions from the Holder thereof.

(f) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with the Registration Rights Agreement, the Issuer shall issue and, upon receipt of an Issuer Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate:

(i) one or more Unrestricted Global Notes in an aggregate principal amount equal to the principal amount of the beneficial interests in the Restricted Global Notes tendered for acceptance, and accepted, in the Exchange Offer by Persons that certify in the applicable Letters of Transmittal or through an Agent’s Message through the DTC Automated Tender Offers Program that (A) they are not broker-dealers, (B) they are not participating in a distribution of the Exchange Notes and (C) they are not affiliates (as defined in Rule 144) of the Issuer; and

(ii) Unrestricted Definitive Notes in an aggregate principal amount equal to the principal amount of the Restricted Definitive Notes tendered for acceptance, in the Exchange Offer by Persons that certify in the applicable Letters of Transmittal that (A) they are not broker-dealers, (B) they are not participating in a distribution of the Exchange Notes and (C) they are not affiliates (as defined in Rule 144) of the Issuer.

Concurrently with the issuance of such Notes, the Trustee shall cause the aggregate principal amount of the applicable Restricted Global Notes to be reduced accordingly, and the Issuer shall execute and the Trustee shall authenticate and deliver to the Persons designated by the Holders of Definitive Notes so accepted Unrestricted Definitive Notes in the appropriate principal amount. Any Notes that remain outstanding after the consummation of an Exchange Offer, and Exchange Notes issued in connection with an Exchange Offer, shall be treated as a single class of securities under this Indenture.

(g) Legends. The following legends shall appear on the face of all Global Notes and Definitive Notes issued under this Indenture unless specifically stated otherwise in the applicable provisions of this Indenture:

(A) Except as permitted by subparagraph (B) below, each Global Note and each Definitive Note (and all Notes issued in exchange therefor or substitution therefor) shall bear the legend in substantially the following form:

AS USED HEREIN, THE

TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.”

(B) Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to subparagraph (b)(iv), (c)(iii), (c)(iv), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) of this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

(iii) Tax Legend. Any Global Notes issued with more than a de minimis amount of original issue discount for U.S. federal income tax purposes and each Definitive Note issued with more than a de minimis amount of original issue discount for U.S. federal income tax purposes shall bear the legend in substantially the following form:

THIS NOTE IS ISSUED WITH ORIGINAL ISSUE DISCOUNT FOR PURPOSES OF SECTION 1271 ET SEQ. OF THE INTERNAL REVENUE CODE OF 1986, AS

AMENDED. A HOLDER MAY OBTAIN THE ISSUE PRICE, AMOUNT OF ORIGINAL ISSUE DISCOUNT, ISSUE DATE AND YIELD TO MATURITY FOR SUCH NOTE BY SUBMITTING A WRITTEN REQUEST FOR SUCH INFORMATION TO THE ISSUER AT THE FOLLOWING ADDRESS: ENERGY FUTURE INTERMEDIATE HOLDING COMPANY LLC, ENERGY PLAZA, 1601 BRYAN STREET, DALLAS, TEXAS 75201-3411, ATTENTION: GENERAL COUNSEL.

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Definitive Notes upon receipt of an 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.

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

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

(viii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuer shall execute, and the Trustee shall authenticate and mail or otherwise deliver in accordance with the procedures of DTC, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02 hereof.

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

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 an 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.

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.

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.

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.

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.

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.

If the Issuer defaults in a payment of cash interest (including Additional Interest, if any) on the Notes, it shall pay the defaulted cash interest (including Additional Interest, if any) in any lawful manner plus, to the extent lawful, interest payable on the defaulted cash interest (including Additional Interest, if any), 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 (including Additional Interest, if any) 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.

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.

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.

If the Issuer elects to redeem the Notes pursuant to Section 3.07 hereof, it shall furnish to the Trustee, at least five Business Days (or such lesser number of days as shall be acceptable to the Trustee) before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to Section 3.03 hereof but not more than 60 days before a Redemption Date, an Officer’s Certificate setting forth (i) the paragraph or subparagraph of such Notes and/or Section of this Indenture pursuant to which the redemption shall occur, (ii) the Redemption Date, (iii) the principal amount of Notes to be redeemed and (iv) the redemption price.

(a) If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes of such series to be redeemed or purchased (a) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed, (b) on a pro rata basis to the extent practicable or (c) by lot or such similar method in accordance with the procedures of DTC.

(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.

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 delivered in accordance with the procedures of DTC, except that notices of redemption may be mailed or delivered 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 and 3.07(b) hereof, notices of redemption may not be conditional.

(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;

(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(b) 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 five Business Days (or such lesser number of days as shall be acceptable to the Trustee) 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.

Once notice of redemption is mailed or delivered in accordance with Section 3.03 hereof or otherwise delivered in accordance with the procedures of DTC, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price (except as provided for in Section 3.07(b) hereof). The notice, if mailed or delivered 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 delivery 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.

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

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 (including Additional Interest, if any) 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 (including Additional Interest, if any) 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.

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.

(a) Notes Make Whole Redemption. At any time prior to May 15, 2016, the Issuer may redeem, in whole or in part, 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 (including Additional Interest, if any) 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.

(b) Notes Equity Redemption. Prior to May 15, 2014, the Issuer may, at its option, on one or more occasions, redeem up to 35% of the aggregate principal amount of Notes at a redemption price equal to 111.000% of the aggregate principal amount thereof, plus accrued and unpaid interest (including Additional Interest, if any) to 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, with the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the sum of the original aggregate principal amount of Initial Notes and any Additional Notes issued under this Indenture after the Issue Date remains outstanding immediately after the occurrence of each such redemption; and provided, further that each such redemption occurs within 90 days of the date of closing of each such Equity Offering. Notice of any redemption upon any Equity Offerings may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuer’s option and discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.

(c) Except pursuant to clause (a) or (b) of this Section 3.07, the Notes shall not be redeemable at the Issuer’s option prior to May 15, 2016.

(d) Notes Optional Redemption. From and after May 15, 2016 the Issuer may redeem Notes, in whole or in part at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest (including Additional Interest, if any,) to 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, if redeemed during the twelve-month period beginning on May 15 of each of the years indicated below:

(e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Except as set forth in this Section 3.08, the Issuer shall not be required to make any mandatory redemption or sinking fund payments with respect to the Notes.

If the Initial Notes would otherwise constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code, at the end of each “accrual period” (as defined in Section 1272(a)(5) of the Code) ending after the fifth anniversary of the Issue Date (each, an “AHYDO Redemption Date”), the Issuer will be required to redeem for cash a portion of the then outstanding Initial Notes equal to the “Mandatory Principal Redemption Amount” (each such redemption, a “Mandatory Principal Redemption”). The redemption price for the portion of the Initial Notes redeemed pursuant to any Mandatory Principal Redemption will be 100% of the aggregate principal amount of such portion of the Initial Notes to be redeemed plus any accrued interest thereon (including Additional Interest, if any) on the date of the redemption. “Mandatory Principal Redemption Amount” means, as of each AHYDO Redemption Date, the portion of the Initial Notes required to be redeemed at such date to prevent the Initial Notes from being treated as “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code.

(viii) that, (A) in the case of an Asset Sale Offer, if the aggregate principal amount of Notes and Senior Indebtedness surrendered by the holders thereof exceeds the Offer Amount, the Trustee shall select the Notes and such Senior Indebtedness to be purchased on a pro rata basis (subject to the limitations set forth in clause (1) of Section 4.10(b) hereof) or (B) in the case of a Collateral Asset Sale Offer, if the aggregate principal amount of Notes and other Secured Lien Debt surrendered by the holders thereof exceeds the Offer Amount, the Trustee shall select the Senior Lien Debt properly tendered to be purchased and, if any Offer Amount remains, the Trustee shall select the Notes and any other Junior Lien Debt to be purchased on a pro rata basis (subject to the limitations set forth in Section 4.10(f) hereof), in each case based on the accreted value or principal amount of the Notes, or such Senior Indebtedness or Secured Lien Debt, as applicable, tendered (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $2,000, or an integral multiple of $1,000 in excess thereof, shall be purchased); and

Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Asset Sale Offer on or as soon as practicable after the Purchase Date.

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

The Issuer shall cause Additional Interest, if any, to be paid in the same manner on the dates and in the amounts set forth in the Registration Rights Agreement.

The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (including Additional Interest, if any) (without regard to any applicable grace period) at the same rate to the extent lawful.

The Issuer shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuer in respect of the Notes and

this Indenture may be served. This office shall initially be the Corporate Trust Office of the Trustee. The Issuer shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

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

(a) franchise and excise taxes and other fees, taxes and expenses required to maintain their corporate existence;

(b) foreign, federal, state and local income taxes, to the extent such income taxes are attributable to the income of EFIH and its Restricted Subsidiaries and, to the extent of the amount actually received from its Unrestricted Subsidiaries; provided that in each case the amount of such payments in any fiscal year does not exceed the amount that EFIH and its Subsidiaries would be required to pay in respect of foreign, federal, state and local taxes for such fiscal year were EFIH, its Restricted Subsidiaries and its Unrestricted Subsidiaries (to the extent described above) to pay such taxes separately from any such parent entity;

(17) Restricted Payments in the form of a dividend to EFH Corp. (so long as EFIH is a Subsidiary of EFH Corp.) of (a) any Existing EFH Corp. Notes or Indebtedness of TCEH received by EFIH (i) in exchange for the 9.75% Notes or the 10.000% Notes in the respective exchange offer relating thereto or otherwise contributed to it or (ii) in exchange for Indebtedness of EFH Corp. or TCEH received in exchange for the 9.75% Notes or the 10.000% Notes in the respective exchange offer related thereto or otherwise contributed to it, or (b) any Indebtedness of EFH Corp. or its Subsidiaries existing on the Issue Date received by EFIH in exchange for Indebtedness of the Issuer or any Guarantor permitted to be incurred under clause (2) of Section 4.09(b) hereof, in each case, including any payments received from the applicable obligor thereon to the extent such payments are excluded when calculating Consolidated Net Income;

(18) Restricted Payments to EFH Corp. (so long as EFIH is a Subsidiary of EFH Corp.) in an aggregate amount since November 16, 2009 not to exceed EFH Corp.’s Ratable

provided, however, that at the time of, and after giving effect to, any Restricted Payment permitted under clauses (7), (11) and (18) of this Section 4.07(b), no Default shall have occurred and be continuing or would occur as a consequence thereof.

For the avoidance of doubt, the spin-off by EFH Corp. of the Equity Interests of EFIH in a Permitted Asset Transfer would not be a Restricted Payment.

EFIH shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the penultimate paragraph of the definition of “Unrestricted Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by EFIH and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated shall be deemed to be Restricted Payments in an amount determined as set forth in the last sentence of the definition of “Investments.” Such designation shall be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to Section 4.07(a) hereof or under clause (7), (10) or (11) of Section 4.07(b) hereof, or pursuant to the definition of “Permitted Investments,” and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

Notwithstanding the foregoing provisions of this Section 4.07, EFIH shall not, and shall not permit any of its Restricted Subsidiaries to, pay any cash dividend or make any cash distribution to EFH Corp. or in respect of EFIH’s Capital Stock or purchase for cash or otherwise acquire for cash any Capital Stock of EFIH or any direct or indirect parent of EFIH for the purpose of paying any cash dividend or making any cash distribution to, or acquiring Capital Stock of any direct or indirect parent of EFIH for cash from, the Investors, or guarantee any Indebtedness of any Affiliate of EFIH for the purpose of paying such dividend, making such distribution or so acquiring such Capital Stock to or from the Investors, in each case by means of utilization of the cumulative Restricted Payment credit provided by Section 4.07(a) hereof, or the exceptions provided by clauses (1), (7) or (11) of Section 4.07(b) hereof or clauses (8), (10) or (13) of the definition of “Permitted Investments,” unless (x) at the time and after giving effect to such payment, the Consolidated Leverage Ratio of EFIH would be equal to or less than 6.00 to 1.00 prior to a Permitted Asset Transfer and 7.00 to 1.00 after a Permitted Asset Transfer and (y) such payment is otherwise in compliance with this Section 4.07.

Section 4.08 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

(a) EFIH shall not, and shall not permit any of its Restricted Subsidiaries that are not Guarantors to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any such Restricted Subsidiary to:

(5) any agreement or other instrument of a Person acquired by EFIH or any Restricted Subsidiary in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired;

(6) contracts for the sale of assets, including customary restrictions with respect to a Subsidiary of EFIH pursuant to an agreement that has been entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Subsidiary;

either (i) the provisions relating to such encumbrance or restriction contained in such Indebtedness are no less favorable to EFIH, taken as a whole, as determined by EFIH in good faith, than the provisions contained in this Indenture on the Issue Date or in the provisions described in the “Description of the Notes” attached to the Exchange Agreements as Appendix B or (ii) any such encumbrance or restriction does not prohibit (except upon a default thereunder) the payment of dividends or loans in an amount sufficient, as determined by EFIH in good faith, to make scheduled payments of cash interest of the Notes when due;

(10) customary provisions in joint venture agreements and other agreements or arrangements relating solely to such joint venture;

(11) customary provisions contained in leases or licenses of intellectual property and other agreements, in each case entered into in the ordinary course of business;

(13) restrictions created in connection with any Receivables Facility for the benefit of EFIH or any of its Restricted Subsidiaries that, in the good faith determination of EFIH, are necessary or advisable to effect the transactions contemplated under such Receivables Facility; and

(14) restrictions or conditions contained in any trading, netting, operating, construction, service, supply, purchase, sale, hedging or similar agreement to which EFIH or any Restricted Subsidiary is a party entered into in the ordinary course of business; provided that such agreement prohibits the encumbrance solely to the property or assets of EFIH or such Restricted Subsidiary that are the subject of such agreement, the payment rights arising thereunder and/or the proceeds thereof and does not extend to any other asset or property of EFIH or such Restricted Subsidiary or the assets or property of any other Restricted Subsidiary.

(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, EFIH, 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, EFIH 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.

(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, EFIH shall not, and shall not permit EFIH Finance or 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 EFIH, EFIH Finance 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 EFIH, EFIH Finance 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.

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

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

(b) any securities received by EFIH or such Restricted Subsidiary from such transferee that are converted by EFIH 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 EFIH 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 November 16, 2009 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.

(b) In respect of Net Proceeds received by EFIH 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, EFIH or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale,

(1) to repay or prepay Secured Lien Debt of EFIH (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 (including to make Restricted Payments to EFH Corp. to permit EFH Corp. to repay or prepay Indebtedness of EFH Corp. (other than Indebtedness owed to a

Subsidiary of EFH Corp.) that is guaranteed by EFIH and constitutes Secured Lien Debt), 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 Secured Lien Debt and the denominator of which is the aggregate principal amount of all Secured Lien Debt (including the Notes), based on amounts outstanding on the date of closing of such Asset Sale; provided that EFIH shall either (x) equally and ratably reduce Obligations under the Notes as provided by Section 3.07 hereof or through open-market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or (y) make an offer (in accordance with the procedures set forth in this Section 4.10) to all Holders to purchase their Notes at 100% of the principal amount thereof plus the amount of accrued and unpaid interest (including Additional Interest, if any);

(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 and unpaid interest (including Additional Interest, if any); or

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

(3) 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

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

provided that, in the case of clauses (3) and (4) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as EFIH, 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, EFIH 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 EFIH 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, EFIH 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 (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture. EFIH 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 or delivering 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, EFIH 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, EFIH may, at its 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 EFIH or any Restricted Subsidiary from Asset Sales of Collateral or other Oncor-related Assets, within 450 days after the receipt by EFIH or any Restricted Subsidiary of any Net Proceeds of any such Asset Sale, EFIH 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 of, and premium, if any, and interest (including Additional Interest, if any) on, and/or to repay or prepay, Senior Lien Obligations of EFIH (or, following the Discharge of Senior Lien Obligations or the repurchase of all Senior Lien Debt in a Collateral Asset Sale Offer described below, Junior Lien Obligations), and, in the case of revolving loans and other similar obligations, permanently reduce the commitment thereunder (including to make Restricted Payments to EFH Corp. to permit EFH Corp. to repay or prepay Indebtedness of EFH Corp. that is guaranteed by EFIH and constitutes Senior Lien Debt (or, following the Discharge of Senior Lien Obligations or the repurchase of all Senior Lien Debt in a Collateral Asset Sale Offer described below, Indebtedness of EFH Corp. that is guaranteed by EFIH and constitutes Junior Lien Debt)).

(g) 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, EFIH and/or any of EFIH’s Restricted Subsidiaries shall make an offer to all Holders of the Notes and, if required or permitted by the terms of any other Secured Lien Debt, to the holders of such other Secured Lien Debt (and if required or permitted by the terms of any Indebtedness of EFH Corp. that is guaranteed by EFIH and constitutes Secured Lien Debt, EFH Corp. may make an offer to all holders of such Indebtedness) (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of such Secured 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 (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the terms and procedures set forth in this Indenture and the other applicable Secured Debt Documents; provided that in any such Collateral Asset Sale Offer, all Senior Lien Debt properly tendered will be purchased before any Junior Lien Debt is purchased; provided that in the event EFIH or such Restricted Subsidiary cannot make an offer to the holders of Senior Lien Debt and holders of Junior Lien Debt at the same time, EFIH or such Restricted Subsidiary may make a Collateral Asset Sale Offer to the holders of Senior Lien Debt first and make a Collateral Asset Sale Offer to the holders of Junior Lien Debt thereafter with any Collateral Excess Proceeds not used to purchase Senior Lien Debt as soon as practicable upon consummation of the Collateral Asset Sale Offer for the Senior Lien Debt. EFIH and/or any of EFIH’s 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 or delivering the notice required pursuant to the terms of this Indenture, with a copy to the Trustee.

(h) To the extent that the aggregate amount of Notes and such Secured Lien Debt tendered pursuant to a Collateral Asset Sale Offer, or sequential Collateral Asset Sales Offer to holders of Senior Lien Debt and Junior Lien Debt as provided for in Section 4.10(g), is less than the Collateral Excess Proceeds, EFIH 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. If the aggregate principal amount of Notes and other Secured Lien Debt surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, all Senior Lien Debt properly tendered shall be purchased before any Junior Lien Debt is purchased and thereafter the Notes and any other Junior Lien Debt shall be purchased on a pro rata basis based upon the accreted value or principal amount of the Notes or such other Junior Lien Debt tendered. Additionally, the Issuer (and, if applicable, EFH Corp.) may, at its 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, or sequential Collateral Asset Sale Offers to holders of Senior Lien Debt and Junior Lien Debt as provided for in Section 4.10(g), any Net Proceeds not required to be used to purchase Secured Lien Debt shall not be deemed Collateral Excess Proceeds and the Issuer and EFIH’s Restricted Subsidiaries may use any remaining Net Proceeds for general corporate purposes, subject to the other covenants contained in this Indenture.

(i) 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.

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

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

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

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

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

(5) transactions in which EFIH or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to EFIH or such Restricted Subsidiary from a financial point of view or stating that the terms are not materially less favorable to EFIH or its relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by EFIH or such Restricted Subsidiary with an unrelated Person on an arm’s-length basis;

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

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

(8) the Transactions (including payments made after the Closing Date in respect of EFIH’s and its Subsidiaries’ or parent companies’ long-term incentive plan or in respect of tax gross-ups and other deferred compensation) and the payment of all fees and expenses related to the Transactions;

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

(10) the issuance of Equity Interests (other than Disqualified Stock) of EFIH to any Permitted Holder or to any director, officer, employee or consultant of EFIH or any of its direct or indirect parent companies;

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

(a) EFIH shall not, and shall not permit EFIH Finance or any Guarantor that is a Restricted Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures obligations under any Indebtedness or any related guarantee, on any asset or property of the Issuer or any Guarantor that is a Restricted Subsidiary, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless:

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

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

except that the foregoing shall not apply to (a) Liens securing Indebtedness permitted to be incurred pursuant to clause (2) or clause (3)(ii) and (iii) 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 (or on a second-priority basis to the extent such Lien is a Lien on the Collateral securing Senior Lien Debt), (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 is being made shall occur would be no greater than 5.0 to 1.0. Any Lien which is granted to secure the Notes under this Section 4.12 shall be discharged at the same time as the discharge of the Lien (other than through the exercise of remedies with respect thereto) that gave rise to the obligation to so secure the Notes.

(b) Notwithstanding Section 4.12(a) hereof, EFIH shall not, directly or indirectly, create, incur, assume or suffer to exist any Lien on the Collateral (other than a Permitted Lien described under clause (3) of the definition of “Permitted Liens”), or any income or profits therefrom, or assign or convey any right to receive income therefrom except:

(2) Junior Liens on the Collateral securing Junior Lien Debt permitted to be incurred pursuant to Section 4.09 hereof.

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

(a) If a Change of Control occurs, unless the Issuer has previously or concurrently mailed or delivered 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 (including Additional Interest, if any) 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 delivered 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;

(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;

(7) that the Holders whose Notes are being repurchased only in part shall be issued new Notes and such new Notes shall be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must be equal to $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 EFIH’s 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.

(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.

Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

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

Section 4.15 Limitation on Guarantees of Indebtedness by Restricted Subsidiaries

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

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

(A) if the 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

(ii) 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 EFIH or any other Restricted Subsidiary as a result of any payment by such Restricted Subsidiary under its Guarantee;

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

EFIH Finance may not hold assets, become liable for any obligations or engage in any business activities; provided that it may be a co-obligor with respect to the Notes, and Additional Notes, any Exchange Notes or any other Indebtedness issued by EFIH and may engage in any activities directly related thereto or necessary in connection therewith.

(d) EFIH shall not sell, assign, transfer, convey or otherwise dispose of any Collateral, including any consideration (other than cash and Cash Equivalents) received by EFIH in an Asset Sale, including in respect of a Permitted Asset Swap of Collateral, except in connection with a sale of all or substantially all of the assets of EFIH in a manner permitted by Section 5.01 hereof or pursuant to an Asset Sale that complies with Section 4.10 hereof pertaining to an Asset Sale of Collateral.

Promptly following the acquisition by EFIH of any Equity Interests in any Oncor Subsidiary or any Indebtedness of, or other Investments in, any Oncor Subsidiary or any property or assets required to be pledged as Collateral pursuant to Section 4.10 hereof or any Equity Interests in or any Indebtedness of, or other Investments in, any Successor Oncor Business, EFIH shall execute and deliver such security instruments, pledges, financing statements and certificates and opinions of counsel as shall be reasonably necessary to vest in the Collateral Trustee a perfected second-priority security interest in such Equity Interests, Indebtedness or other Investments or property or assets and to have such Equity Interests, Indebtedness or other Investments or property or assets added to the Collateral and thereupon all provisions of this Indenture relating to the Collateral shall be deemed to relate to such Equity Interests, Indebtedness or other Investments or property or assets to the same extent and with the same force and effect.

(a) EFIH shall not grant to any Person, or permit any Person to retain (other than the Collateral Trustee), any interest whatsoever in the Collateral, other than pursuant to clause (3) of the definition of “Permitted Liens.”

(b) EFIH and its Restricted Subsidiaries shall not enter into any agreement that requires the proceeds received from any sale of Collateral to be applied to repay, redeem, defease or otherwise acquire or retire any Indebtedness of any Person, other than as permitted by this Indenture, the Notes or the Security Documents.

(c) EFIH shall, at its sole cost and expense, execute and deliver all such agreements and instruments as necessary, or as the Trustee shall reasonably request, to more fully or accurately describe the assets and property intended to be Collateral or the obligations intended to be secured by the Pledge Agreement or any other Security Document.

(a) EFIH, at its own expense, shall 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 Notes are issued), 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, shall promptly execute, acknowledge and deliver such 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, in each case as contemplated by the Secured Debt Documents for the benefit of the holders of Secured Debt Obligations.

(a) EFIH shall not consolidate or merge with or into or wind up into (whether or not EFIH 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) EFIH is the surviving corporation or the Person formed by or surviving any such consolidation, wind-up or merger (if other than EFIH) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, partnership, limited liability company or trust organized or existing under the laws of the jurisdiction of organization of EFIH 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”);

(2) the Successor Company, if other than EFIH, and, to the extent the Successor Company is not a corporation, a Subsidiary of such Successor Company that is a co-obligor and a corporation organized or existing under the laws of the United States, any state of the United States, the District of Columbia or any territory thereof, expressly assumes all the obligations of EFIH under (i) the Notes, this Indenture and the Security Documents, to the extent EFIH is a party thereto, pursuant to a supplemental indenture or other document or instrument in form reasonably satisfactory to the Trustee; provided that in the case of a merger of EFIH with and into EFH Corp., such supplemental indenture shall amend the definitions, covenants, events of default and other terms of this Indenture such that the amended terms shall be substantially similar to those of the EFH Corp. 9.75% Notes Indenture and (ii) the Registration Rights Agreement;

(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 EFIH, 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 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 EFIH and its Restricted Subsidiaries immediately prior to such transaction;

(5) in connection with a Permitted Asset Transfer other than a merger of EFIH with and into EFH Corp., the rating on the Notes shall not have been downgraded by two or more of the Rating Agencies (or, if the Notes are rated by only one Rating Agency at the time of the first notice of such Permitted Asset Transfer, such Rating Agency) during the period commencing 30 days prior to the first public notice of the occurrence of a Permitted Asset Transfer or the intention of the Issuer or any Subsidiary thereof to effect a Permitted Asset Transfer and ending on the date 60 days after such notice relative to the rating at the start of such period;

(6) each Guarantor, unless it is the other party to the transactions described above, in which case clause (1)(B) of Section 5.01(c) 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, the Notes and the Registration Rights Agreement; and

(7) EFIH 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, a transaction meeting the requirements of the proviso to clause (1) under the definition of “Change of Control” shall not be deemed to be a sale, assignment, transfer, conveyance or other disposition of all or substantially all of the properties or assets of EFIH and its Subsidiaries. For the avoidance of doubt, EFIH may consummate a transaction meeting the requirements of the proviso to clause (1) under the definition of “Change of Control” without

complying with this Section 5.01, and the determination in the preceding proviso shall not affect the determination of what constitutes all or substantially all the assets of EFIH and its Subsidiaries under any other agreement to which EFIH is a party.

(1) any Restricted Subsidiary may consolidate with or merge into or transfer all or part of its properties and assets to EFIH, and

(2) EFIH may merge with an Affiliate of EFIH solely for the purpose of reincorporating EFIH in a State of the United States, the District of Columbia or any territory thereof so long as the amount of Indebtedness of EFIH and its Restricted Subsidiaries is not increased thereby.

(c) Subject to Section 11.06 hereof, no Guarantor shall, and EFIH shall not permit any Guarantor to, consolidate or merge with or into or wind up into (whether or not EFIH or the Guarantor 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) (A) such Guarantor is the surviving corporation or the Person formed by or surviving any such consolidation, wind-up or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor, as the case may be, or the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (such Guarantor or such Person, as the case may be, being herein called the “Successor Person”);

(B) the Successor Person, if other than such Guarantor, expressly assumes all the obligations of such Guarantor under this Indenture and such Guarantor’s related Guarantee and any Security Documents to which such Guarantor is a party pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee;

(D) EFIH 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 indentures, if any, comply with this Indenture; or

(d) Notwithstanding Section 5.01(c) hereof, any Guarantor may (i) merge into or transfer all or part of its properties and assets to another Guarantor or EFIH, (ii) merge with an Affiliate of EFIH solely for the purpose of reincorporating the Guarantor in the United States, any state thereof, the District of Columbia or any territory thereof or (iii) convert into a corporation, partnership, limited partnership, limited liability corporation or trust organized or existing under the laws of the jurisdiction of organization of such Guarantor.

(e) EFIH Finance may not consolidate or merge with or into or wind up into (whether or not EFIH Finance is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of

all or substantially all of EFIH Finance’s properties or assets, in one or more related transactions, to any Person unless:

(1) (A) concurrently therewith, a corporate Wholly-Owned Subsidiary of EFIH 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 under the Notes and this Indenture pursuant to a supplemental indenture or other documents or instruments in form reasonably satisfactory to the Trustee; or

(B) after giving effect thereto, at least one obligor on the Notes shall be a corporation organized or existing under the laws of the United States, any state thereof, the District of Columbia, or any territory thereof; and

(3) EFIH Finance 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 supplement shall comply with the applicable provisions of this Indenture.

Upon any consolidation, wind-up or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of EFIH or any Guarantor in accordance with Section 5.01 hereof (other than a consolidation, wind-up or merger or a sale or other disposition of all or substantially all of the assets of a Guarantor made in compliance with Section 4.10 hereof), the successor corporation formed by such consolidation or into or with which EFIH or such Guarantor, as the case may be, is merged or wound up or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, wind-up, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to EFIH or such Guarantor, as the case may be, shall refer instead to the successor corporation and not to EFIH or such Guarantor, as the case may be), and may exercise every right and power of EFIH or such Guarantor, as the case may be, under this Indenture with the same effect as if such successor Person had been named as EFIH or such Guarantor, as the case may be, herein; provided, that the predecessor EFIH shall not be relieved from the obligation to pay the principal of and premium, if any, and interest (including Additional Interest if any) on the Notes, and such Guarantor shall not be released from its Guarantee, except in the case of a sale, assignment, transfer, conveyance or other disposition of all of EFIH’s or such Guarantor’s, as the case may be, assets that meets the requirements of Section 5.01 hereof.

(a) An “Event of Default” wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(1) default in payment when due and payable, upon redemption, acceleration or otherwise, of principal, or premium, if any, on the Notes;

(2) default for 30 days or more in the payment when due of interest (including Additional Interest, if any) on or with respect to the Notes;

(3) failure by the Issuer or any Restricted Subsidiary for 60 days after receipt of written notice given by the Trustee or the Required Holders of not less than 30% in principal amount of the outstanding Required Debt to comply with any of its obligations, covenants or agreements (other than a default referred to in clauses (1) and (2) above) contained in this Indenture, the Notes or the Security Documents relating to the Notes;

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

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

(b) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $250.0 million or more at any one time outstanding;

(5) failure by the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $250.0 million, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed;

(6) the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), pursuant to or within the meaning of any Bankruptcy Law:

(ii) consents to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under applicable Bankruptcy Law;

(iii) consents to the appointment of a receiver, liquidator, assignee, trustee, sequestrator or other similar official of it or for all or substantially all of its property;

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

(i) is for relief against the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), in a proceeding in which the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), is to be adjudicated bankrupt or insolvent;

(ii) appoints a receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary), or for all or substantially all of the property of the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary); or

(iii) orders the liquidation of the Issuer or any Significant Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary);

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

(9) with respect to Collateral having a fair market value in excess of $250.0 million in the aggregate, any security interest and Lien purported to be created by any Security Document with respect to the Collateral (a) ceases to be in full force and effect, (b) ceases to give the Collateral Trustee, for the benefit of the Holders of the Notes, the Liens, rights, powers and privileges purported to be created and granted thereby (including a perfected second-priority security interest in and Lien on, all of the Collateral thereunder) in favor of the Collateral Trustee, or (c) is asserted by EFIH not to be, a valid, perfected, second priority (except as otherwise expressly provided in this Indenture or the Collateral Trust Agreement) security interest in or Lien on the Collateral covered thereby.

(b) In the event of any Event of Default specified in clause (4) of Section 6.01(a) hereof, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within 20 days after such Event of Default arose:

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

(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

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 Required Holders of at least 30% in aggregate principal amount of the outstanding Required Debt may declare the principal of and premium, if any, interest (including Additional Interest, if any) 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, premium, interest (including Additional Interest, if any) and such other monetary obligations 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 principal of and premium, if any, interest (including Additional Interest, if any) and any other monetary obligations on the outstanding Notes shall be due and payable immediately without further action or notice.

The Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt by written notice to the Trustee may on behalf of all of the Required Holders waive any existing Default and its consequences under this Indenture except a continuing Default in the payment of interest (including Additional Interest, if any) 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).

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of and premium, if any, and interest (including Additional Interest, if any) 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.

The Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt by notice to the Trustee may on behalf of the Required Holders of all of the Required Debt waive any existing Default and its consequences hereunder, except a continuing Default in the payment of the principal of, or premium, if any, or interest (including Additional Interest, if any) 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 Required Holders of a majority in aggregate principal amount of the then outstanding Required Debt 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.

The Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt 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.

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) the Required Holders of at least 30% in aggregate principal amount of the outstanding Required Debt have requested the Trustee to pursue the remedy;

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

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

(5) the Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt 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.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of and premium, if any, and interest (including Additional Interest, if any) on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale Offer, a Collateral 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.

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 (including Additional Interest, if any) remaining unpaid on the Notes and interest on overdue principal and, to the

extent lawful, interest (including Additional Interest, if any) 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.

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.

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.

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.

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.

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 (including Additional Interest, if any), 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 (including Additional Interest, if any), 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.

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

(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.

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this

Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

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

(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.

(e) The Trustee shall be under no obligation to exercise any of its rights or powers under this Indenture at the request or direction of any Holder of the Notes unless such Holder shall have offered to the Trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense.

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(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. The Trustee may consult with counsel of its selection and the written advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(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.

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

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

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

(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. Delivery of reports to the Trustee pursuant to Section 4.03 hereof shall not constitute actual knowledge of, or notice to, the Trustee of information contained therein.

(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.

(j) In the event the Issuer is required to pay Additional Interest, the Issuer will provide written notice to the Trustee of the Issuer’s obligation to pay Additional Interest no later than 15 days prior to the next succeeding Interest Payment Date, which notice shall set forth the amount of the Additional Interest to be paid by the Issuer. The Trustee shall not at any time be under any duty or responsibility to any Holders to determine whether the Additional Interest is payable and the amount thereof.

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

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.

If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail or otherwise deliver in accordance with the procedure of DTC 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 of or premium, if any, or interest (including Additional Interest, if any) 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.

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.

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.

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.

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:

(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;

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.

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Issuer’s expense), the Issuer or the Holders of at least 10% in

principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

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

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

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act Section 310(b).

The Trustee is subject to Trust Indenture Act Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated therein.

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.

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 of and premium, if any, and interest (including Additional Interest, if any) 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

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.

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, 4.18, 4.19, 4.20 and 4.21 hereof and clauses (3), (4) and (5) 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

hereof, clauses (3), (4), (5) and (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.

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

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

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

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

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

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the Holders of the Notes shall not recognize income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and 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 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 (including Additional Interest, if any), 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.

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 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.

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.

Notwithstanding Section 9.02 of this Indenture, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes, the Guarantees or any Security Document at any time after the Issue Date without the consent of any Holder to:

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

(4) provide for the assumption of the Issuer’s or any Guarantor’s obligations to the Holders;

(5) make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect the legal rights under this Indenture of any such Holder;

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

(7) comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the Trust Indenture Act;

(8) evidence and provide for the acceptance and appointment under this Indenture of a successor Trustee thereunder pursuant to the requirements thereof;

(9) to provide for the issuance of Additional Notes or additional debt securities that constitute Required Debt; provided that such Additional Notes or additional debt securities are issued in compliance with the provisions of this Indenture, including those described in Section

4.09, and such amendments or supplements are limited to changes necessary or appropriate in order to issue such Additional Notes or additional debt securities under this Indenture;

(10) to provide for the issuance of Exchange Notes or private exchange notes that are identical to Exchange Notes except that they are not freely transferable;

(12) conform the text of this Indenture, the Guarantees, the Notes or any Security Document to any provision of the “Description of the Notes” attached to the Exchange Agreements as Appendix B to the extent such provision in such “Description of the Notes” was intended to be a verbatim recitation of a provision of this Indenture, the Guarantees, the Notes or any Security Document;

(13) 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;

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

(15) provide for the accession or succession of any parties to the Security Documents (and other amendments that are administrative or ministerial in nature) in connection with an amendment, renewal, extension, substitution, refinancing, restructuring, replacement, supplementing or other modification from time to time of any agreement or action that is not prohibited by this Indenture, including to add any additional secured parties to the extent not prohibited by this Indenture.

Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Sections 7.02 and 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 D hereto, and delivery of an Officer’s Certificate.

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 Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Required Debt) and, subject to Sections 6.04 and

6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of or premium or interest (including Additional Interest, if any) 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 the consent of the Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, the Required Debt) other than Required Debt beneficially owned by the Issuer or EFIH’s 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 Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt 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 3.08, Section 3.09, Section 4.10 and Section 4.14 hereof are not redemptions of Notes);

(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 Required Holders of at least a majority in aggregate principal amount of the outstanding Required Debt 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;

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

(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 Required Debt 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 Required Debt 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 Required Debt 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.

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.

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.

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.

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

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.

(1) anything contained in the Collateral Trust Agreement or in any other Security Document;

(3) the order or method of attachment or perfection of any Liens securing any Series of Junior Lien Debt;

(4) the time or order of filing or recording of financing statements or other documents filed or recorded to perfect any Junior Lien upon any Collateral;

(7) the rules for determining priority under any law governing relative priorities of Liens,

all Junior Liens granted at any time by EFIH shall secure, equally and ratably, all present and future Junior Lien Obligations.

(b) Section 10.01(a) hereof is intended for the benefit of, and shall be enforceable as a third party beneficiary by, each present and future holder of Junior Lien Obligations, each present and future Junior Lien Representative and the Collateral Trustee as holder of Junior Liens.

(4) the time or order of filing or recording of financing statements or other documents filed or recorded to perfect any Lien upon any Collateral;

(7) the rules for determining priority under any law governing relative priorities of Liens,

all Junior Liens at any time granted by EFIH (including the Junior Liens securing the Notes) shall be subject and subordinate to all Senior Liens securing Senior Lien Obligations.

(b) The provisions described in Section 10.02(a) hereof are intended for the benefit of, and shall be enforceable as a third party beneficiary by, each present and future holder of Senior Lien Obligations, each present and future Senior Lien Representative and the Collateral Trustee as holder of Senior Liens.

(1) impair, as between EFIH and the Holders of the Notes, the obligation of EFIH to pay principal of and premium, if any, and interest (including Additional Interest, if any) on the Notes in accordance with their terms or any other obligation of EFIH under this Indenture;

(2) affect the relative rights of Holders of Notes as against any other creditors of EFIH (other than holders of Senior Liens or other Junior Liens);

(3) restrict the right of any Holder of Notes to sue for payments that are then due and owing (but not enforce any judgment in respect thereof against any Collateral to the extent specifically prohibited by the provisions of the Collateral Trust Agreement);

(4) restrict or prevent any Holder of Notes or holder of other Junior Lien Obligations, the Collateral Trustee or any other Person from exercising any of its rights or remedies upon a Default or Event of Default not specifically restricted or prohibited by the provisions of the Collateral Trust Agreement; or

(5) restrict or prevent any Holder of Notes or holder of other Junior Lien Obligations, the Trustee, the Collateral Trustee or any other Person from taking any lawful action in an insolvency or liquidation proceeding not specifically restricted or prohibited by the provisions of the Collateral Trust Agreement.

The due and punctual payment of the principal of and premium, if any, and interest (including Additional Interest, if any) on the Notes when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of and premium, if any, and interest (including Additional Interest, if any) (to the extent permitted by law), on the Notes and performance of all other Obligations of EFIH to the Holders of Notes or the Trustee under this Indenture and the Notes, according to the terms hereunder or thereunder, are secured as provided in the Pledge Agreement and the Collateral Trust Agreement. Each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of the Pledge Agreement and Collateral Trust Agreement (including, without limitation, the provisions providing for foreclosure and release of Collateral) as the same may be in effect or may be amended from time to time in accordance with their terms and authorizes and directs the Collateral Trustee and/or the Trustee (as the case may be) to enter into the Pledge Agreement, the Collateral Trust Agreement and any other Security Document and to perform its obligations and exercise its rights thereunder in accordance therewith.

EFIH, at its own expense, shall deliver to the Trustee copies of all documents delivered to the Collateral Trustee pursuant to the Pledge Agreement and Collateral Trust Agreement, and shall do or cause to be done all such acts and things as may be necessary or proper, or as may be required by the provisions of the Pledge Agreement or the Collateral Trust Agreement, to assure and confirm to the Trustee and the Collateral Trustee the security interest in the Collateral contemplated hereby, by the Pledge Agreement or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture and of the Notes secured hereby, according to the intent and purposes herein expressed. Subject to the terms of the Pledge Agreement, EFIH, at its own expense, shall take, upon request of the Trustee, any and all actions reasonably required to cause the Pledge Agreement to create and maintain, as security for the Obligations of EFIH hereunder, a valid and enforceable perfected Lien in and on all the Collateral, in favor of the Collateral Trustee for the benefit of the Holders of Notes and future permitted Junior Lien Obligations, superior to and prior to the rights of all third Persons and subject to no other Liens other than Permitted Liens and other Liens pursuant to Section 4.12 hereof.

The Issuer shall comply with the provisions of TIA §314(b) (including, without limitation, the provision of an initial and annual Opinion of Counsel under TIA §314(b)). To the extent the Issuer is required to furnish to the Trustee an Opinion of Counsel pursuant to TIA §314(b)(2), the Issuer shall furnish such opinion not more than 60 but not less than 30 days prior to each December 31.

(a) The Collateral Trustee’s Liens upon the Collateral shall no longer secure the Notes and Guarantees outstanding under this Indenture or any other Obligations under this Indenture, and the right of the Holders of the Notes and such Obligations to the benefits and proceeds of the Collateral Trustee’s Liens on the Collateral shall terminate and be discharged:

(1) upon satisfaction and discharge of this Indenture in accordance with Article 12 hereof;

(2) upon a Legal Defeasance or Covenant Defeasance of the Notes in accordance with Article 8 hereof;

(3) upon payment in full of the Notes and all other Note Obligations that are outstanding, due and payable at the time the Notes are paid in full;

(4) in whole or in part, with the consent of the holders of the requisite percentage of Secured Lien Debt and/or Junior Lien Debt in accordance with the provisions set forth in the Security Documents, and upon delivery of instructions and any other documentation, in each case as required by this Indenture and the Security Documents, in a form satisfactory to the Collateral Trustee; or

(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 EFIH 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.

(b) To the extent applicable, the Issuer shall cause TIA §313(b), relating to reports, and TIA §314(d), relating to the release of property or securities or relating to the substitution therefore of any property or securities to be subjected to the Lien created by the Security Documents, to be complied with. 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:

(2) an Opinion of Counsel to the effect that such accompanying documents constitute all documents required by TIA §314(d).

Section 10.07 Authorization of Actions to Be Taken by the Trustee Under the Security Documents.

(a) Subject to the provisions of the Security Documents, the Trustee may (but shall have no obligation to), in its sole discretion and without the consent of the Holders of Notes, direct, on behalf of the Holders of Notes, the Collateral Trustee to, take all actions it deems necessary or appropriate in order to:

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

(b) The Trustee shall have power (but shall have no obligation) to direct, on behalf of the Holders of the Notes, the Collateral Trustee to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Pledge Agreement or this Indenture, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests of the Holders of Notes in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes or of the Trustee).

Section 10.08 Authorization of Receipt of Funds by the Trustee under the Pledge Agreement.

The Trustee is authorized to receive any funds for the benefit of the Holders of Notes distributed under the Pledge Agreement and/or the Collateral Trust Agreement, and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

The Trustee agrees for itself and on behalf of the Holders of the Notes, and by holding Notes each such Holder shall be deemed to agree:

(a) for the enforceable benefit of all holders of each existing and future Series of Senior Lien Debt and Series of Junior Lien Debt, and each existing and future Senior Lien Representative and Junior Lien Representative, that all Junior Lien Obligations shall be and are secured equally and ratably by all Junior Liens at any time granted by the Issuer or any Guarantor to secure any Obligations in respect of this Indenture, the Notes and any Guarantees, and that all such Junior Liens shall be enforceable by the Collateral Trustee for the benefit of all holders of Junior Lien Obligations equally and ratably;

(b) for the enforceable benefit of all holders of each existing and future Series of Senior Lien Debt and Series of Junior Lien Debt, and each existing and future Senior Lien Representative and Junior Lien Representative, that the holders of Obligations in respect of this Indenture, the Notes and the Guarantees are bound by the provisions of the Collateral Trust Agreement, including the provisions relating to the ranking of Junior Liens and the order of application of proceeds from enforcement of Junior Liens; and

(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.

In connection with any matter under the Collateral Trust Agreement requiring a vote of holders of Secured Lien Debt, the Holders shall cast their votes in accordance with this Indenture. The amount of the Notes to be voted by the Holders shall equal the aggregate outstanding principal amount of the Notes outstanding at the time of such vote. 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, any Guarantors, the Secured Debt Representatives or the Collateral Trustee.

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 Section 4.10(f) hereof. Such funds shall also be released to repurchase Notes and other Secured Lien Debt and to make related payments in connection with a Collateral Asset Sale Offer pursuant to Sections 4.10(g) and 4.10(h) hereof and/or upon consummation of any Collateral Asset Sale Offer, whether or not any Collateral Excess Proceeds remain. The Issuer 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, other Junior Lien Obligations and/or Senior Lien Obligations in accordance with Section 4.10(f).

This Article 10 is intended for the benefit of, and shall be enforceable as a third party beneficiary by, the Collateral Trustee as holder of Senior Liens.

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 of and premium, if any, and interest (including Additional Interest, if any) 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 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 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.

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.

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.

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.

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.

(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;

(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;

(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.

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) (A) 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 and unpaid interest to the date of maturity or redemption;

(B) no Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect to this Indenture or the Notes shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit, and such deposit 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);

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

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

Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subclause (A) of clause (2) of this Section 12.01, the provisions of Section 12.02 and Section 8.06 hereof shall survive.

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, if any, and interest (including Additional Interest, if any) 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.

If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by Trust Indenture Act § 318(c), the imposed duties shall control.

Any notice or communication by the Issuer, any Guarantor or the Trustee to the others is duly given if in writing and delivered in Person or by first class mail (registered or certified, return receipt requested), facsimile transmission or overnight air courier guaranteeing next day delivery, to the others’ address:

The Issuer, any Guarantor, or the Trustee, by notice to the others, may designate additional or different addresses for subsequent notices or communications.

All notices and communications (other than those sent to Holders) shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five calendar days after being deposited in the mail postage prepaid, if mailed; when receipt acknowledged, if transmitted by facsimile; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery; provided that any notice or communication delivered to the Trustee shall be deemed effective upon actual receipt thereof.

Any notice or communication to a Holder shall be mailed by first class mail, certified or registered, return receipt requested, or by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar. Any notice or communication shall also be so mailed to any Person described in Trust Indenture Act § 313(c), to the extent required by the Trust Indenture Act. Failure to mail a notice or communication to a Holder or any defect in it shall not affect its sufficiency with respect to other Holders.

If a notice or communication is mailed in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

If the Issuer mails a notice or communication to Holders, it shall mail a copy to the Trustee and each Agent at the same time.

Holders may communicate pursuant to Trust Indenture Act § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the Trustee, the Registrar and anyone else shall have the protection of Trust Indenture Act § 312(c).

Upon any request or application by the Issuer or any of the Guarantors to the Trustee to take any action under this Indenture, the Issuer or such Guarantor, as the case may be, shall furnish to the Trustee:

(a) an Officer’s Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 13.05 hereof) stating that, in the opinion of the signers, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and

(b) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 13.05 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been satisfied.

Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to Section 4.04 hereof or Trust Indenture Act § 314(a)(4)) shall comply with the provisions of Trust Indenture Act § 314(e) and shall include:

(a) a statement that the Person making such certificate or opinion has read such covenant or condition;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(c) a statement that, in the opinion of such Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with (and, in the case of an Opinion of Counsel, may be limited to reliance on an Officer’s Certificate as to matters of fact); and

(d) a statement as to whether or not, in the opinion of such Person, such condition has been satisfied or such covenant has been complied with.

The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions.

Section 13.07 No Personal Liability of Directors, Officers, Employees and Stockholders.

No past, present or future director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, shall have any liability for any obligations of the Issuer or the Guarantors under the Notes, this Indenture, the Guarantees, the Registration Rights Agreement or any Security Document or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.

THIS INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

EACH OF THE ISSUER, THE GUARANTORS AND THE TRUSTEE HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR THE TRANSACTIONS CONTEMPLATED HEREBY.

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

(1) INTEREST. Energy Future Intermediate Holding Company LLC, a Delaware limited liability company (“EFIH”), and EFIH Finance Inc., a Delaware corporation (collectively, the “Issuer”), promise to pay interest on the principal amount of this Note at 11% per annum from April 25, 2011 until maturity and shall pay Additional Interest, if any, payable pursuant to the Registration Rights Agreement referred to below. The Issuer will pay interest (including Additional Interest, if any) semi-annually in arrears on May 15 and November 15 of each year, commencing on November 15, 2011, 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 (including Additional Interest, if any)(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 (including Additional Interest, if any) to the Persons who are registered Holders of Notes at the close of business on the May 1 or November 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 (including Additional Interest, if any) may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of, and premium, if any, and interest (including Additional Interest, if any) 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 April 25, 2011 (the “Indenture”), between the Issuer and the Trustee. This Note is one of a duly authorized issue of notes of the Issuer designated as its 11% Senior Secured Second Lien Notes due 2021 (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. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

(a) Except as set forth below, the Issuer will not be entitled to redeem Notes at its option prior to May 15, 2016.

(b) At any time prior to May 15, 2016, the Issuer may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to the registered address of each Holder of Notes or otherwise delivered in accordance with procedures of DTC, at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium, plus accrued and unpaid interest (including Additional Interest, if any) to the applicable 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.

(c) From and after May 15, 2016, the Issuer may redeem the Notes, in whole or in part, upon not less than 30 nor more than 60 days’ prior notice mailed by first class mail to the registered address of each Holder of Notes or otherwise delivered in accordance with the procedures of DTC, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest (including Additional Interest, if any) to the applicable 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, if redeemed during the twelve-month period beginning on May 15 of each of the years indicated below:

(d) Prior to May 15, 2014, the Issuer may, at its option, on one or more occasions, redeem up to 35% of the aggregate principal amount of all Notes at a redemption price equal to 111.000% of the aggregate principal amount thereof, plus accrued and unpaid interest (including Additional Interest, if any) to 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, with the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the sum of the original aggregate principal amount of Initial Notes and any Additional Notes issued under the Indenture after the Issue Date remains outstanding immediately after the occurrence of each such redemption; provided further that each such redemption occurs within 90 days of the date of closing of each such Equity Offering. Notice of any redemption upon any Equity Offerings may be given prior to the redemption thereof, and any such redemption or notice may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering.

(e) If the Issuer redeems less than all of the outstanding Notes, the Trustee shall select the Notes to be redeemed in the manner described under Section 3.02 of the Indenture.

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

(6) MANDATORY REDEMPTION. Except as set forth below, the Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

If the Initial Notes would otherwise constitute “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code, at the end of each “accrual period” (as defined in Section 1272(a)(5) of the Code) ending after the fifth anniversary of the Issue Date (each, an “AHYDO Redemption Date”), the Issuer will be required to redeem for cash a portion of the then outstanding Initial Notes equal to the “Mandatory Principal Redemption Amount” (each such redemption, a “Mandatory Principal Redemption”). The redemption price for the portion of the Initial Notes redeemed pursuant to any Mandatory Principal Redemption will be 100% of the aggregate principal amount of such portion of the Initial Notes to be redeemed plus any accrued interest thereon (including Additional Interest, if any) on the date of the redemption. “Mandatory Principal Redemption Amount” means, as of each AHYDO Redemption Date, the portion of the Initial Notes required to be redeemed at such date to prevent the Initial Notes from being treated as “applicable high yield discount obligations” within the meaning of Section 163(i)(1) of the Code. No partial redemption or repurchase of the Initial Notes prior to any AHYDO Redemption Date pursuant to any other provision of the Indenture will alter the Issuer’s obligation to make any Mandatory Principal Redemption with respect to the Initial Notes that remain outstanding on such AHYDO Redemption Date.

(7) NOTICE OF REDEMPTION. Subject to Section 3.03 of the Indenture, notice of redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date (except that redemption notices may be mailed or delivered more than 60 days prior to a Redemption Date if the notice is issued in connection with Article 8 or Article 12 of the Indenture) to each Holder whose Notes are to be redeemed at its registered address or otherwise delivered in accordance with the procedures of DTC. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 in excess thereof, unless all of the Notes held by a Holder are to be redeemed. On and after the Redemption Date interest ceases to accrue on Notes or portions thereof called for redemption.

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

(b) If EFIH or any of its Restricted Subsidiaries consummates an Asset Sale (other than an Asset Sale of Collateral or other Oncor-related Assets), within 10 Business Days of each date that the aggregate amount of Excess Proceeds exceeds $200.0 million, EFIH 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 (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes, and such Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, EFIH 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.

(c) EFIH may, at its option, make an Asset Sale Offer using proceeds from any Asset Sale at any time after consummation of such Asset Sale (other than an Asset Sale of Collateral or other Oncor-related Assets); 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.

(d) If EFIH or any of its Restricted Subsidiaries consummates an Asset Sale of Collateral or other Oncor-related Assets, within 10 Business Days of each date that the aggregate amount of Collateral Excess Proceeds exceeds $200.0 million, EFIH 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 other Secured Lien Debt, to the holders of such other Secured Lien Debt (and if required or permitted by the terms of any Indebtedness of EFH Corp. that is guaranteed by EFIH and constitutes Secured Lien Debt, EFH Corp. may make an offer to all holders of such Indebtedness) (a “Collateral Asset Sale Offer”), to purchase the maximum aggregate principal amount of such Secured 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 (including Additional Interest, if any) to the date fixed for the closing of such offer, in accordance with the terms and procedures set forth in the Indenture and the other applicable Secured Debt Documents; provided that in any such Collateral Asset Sale Offer, all Senior Lien Debt properly tendered will be purchased before any Junior Lien Debt is purchased; provided that in the event EFIH or such Restricted Subsidiary cannot make an offer to the holders of Senior Lien Debt and holders of Junior Lien Debt at the same time, EFIH or such Restricted Subsidiary may make a Collateral Asset Sale Offer to the holders of Senior Lien Debt first and make a Collateral Asset Sale Offer to the holders of Junior Lien Debt thereafter with any Collateral Excess Proceeds not used to purchase Senior Lien Debt as soon as practicable upon consummation of the Collateral Asset Sale Offer for the Senior Lien Debt. To the extent that the aggregate amount of Notes and such Secured Lien Debt tendered pursuant to a Collateral Asset Sale Offer, or sequential Collateral Asset Sale Offers to holders of Senior Lien Debt and Junior Lien Debt as provided for in the immediately preceding paragraph, is less than the Collateral Excess Proceeds, EFIH 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. If the aggregate principal amount of Notes and other Secured Lien Debt surrendered by such holders thereof exceeds the amount of Collateral Excess Proceeds, all Senior Lien Debt properly tendered will be purchased before any Junior Lien Debt is purchased and thereafter the Notes and any other Junior Lien Debt will be purchased on a pro rata basis based upon the accreted value or principal amount of the Notes or such other Junior Lien Debt tendered.

(e) The Issuer (and, if applicable, EFH Corp.) may, at its 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, or sequential Collateral Asset Sale Offers to holders of Senior Lien Debt and Junior Lien Debt, any Net Proceeds not required to be used to purchase Secured Lien Debt shall not be deemed Collateral Excess Proceeds and the Issuer and EFIH’s Restricted Subsidiaries may use any remaining Net Proceeds for general corporate purposes, subject to the other covenants contained in the Indenture.

(9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the

Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer of any Notes or portion of Notes selected for redemption, except for the unredeemed portion of any Notes being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

(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 Required Holders of at least 30% in aggregate principal amount of the then outstanding Required Debt may declare the principal of and premium, if any, interest (including Additional Interest, if any) 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 principal of, and premium, if any, interest (including Additional Interest, if any) and any other monetary obligations on, all the then 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, Required Holders of a majority in aggregate principal amount of the then outstanding Required Debt 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 (including Additional Interest, if any)) if it determines that withholding notice is in their interest. The Required Holders of a majority in aggregate principal amount of the then outstanding Required Debt by notice to the Trustee may on behalf of the Required Holders of all of the Required Debt waive any existing Default or and its consequences under the Indenture except a continuing Default in payment of the principal of, or premium, if any, or interest (including Additional Interest, if any) on, any of the Notes held by a non-consenting Holder. EFIH is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and EFIH 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 EFIH 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.

In addition to the rights provided to Holders of Notes under the Indenture, Holders of Restricted Global Notes and Restricted Definitive Notes shall have all the rights set forth in the Registration Rights Agreement, dated as of April 25, 2011, among the Issuer and the other parties named on the signature pages thereof (the “Registration Rights Agreement”), including the right to receive Additional Interest, if any (as defined in the Registration Rights Agreement).

(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, the Registration Rights Agreement and/or the Security Documents. Requests may be made to the Issuer at the following address:

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 any 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 of and premium, if any, and interest (including Additional Interest, if any) 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

(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 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 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 Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

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

(l) This Guarantee shall be a general senior [unsecured] [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 all 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.

(1) (A) any sale, exchange or transfer (by merger, wind-up, consolidation or otherwise) of the Capital Stock of the Guaranteeing Subsidiary (including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or sale of all or substantially all the assets of the Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture;

(within the meaning of Article 8 of the UCC), use its commercially reasonable efforts to cause the issuer of such Pledged Equity to enter into an Uncertificated Securities Control Agreement pursuant to clause (b) above.

(f) At such time as any Pledgor has or acquires any Security Collateral in which such Pledgor has any right, title or interest and that is not a security (within the meaning of Article 8 of the UCC), such Pledgor agrees that the Collateral Trustee may file a financing statement in the relevant jurisdiction.

(g) No Pledgor shall take or omit to take any action which would or could reasonably be expected to have the result of materially adversely affecting or impairing the Liens in favor of the Collateral Trustee and the holders of Junior Lien Obligations with respect to the Collateral.

Section 6. Maintaining the Pledged Account. From and after the date on which the Pledged Account is established in accordance with the terms of each Indenture, and for so long as any Obligation of any Pledgor under any Junior Lien Document shall remain unpaid:

(d) Amounts in the Pledged Account shall be invested in accordance with the terms of each of the Indentures.

Section 7. Representations and Warranties. Each Pledgor represents and warrants as follows:

(a) Such Pledgor’s exact legal name, as defined in Section 9-503(a) of the UCC, is correctly set forth in Schedule I hereto. 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.

(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 11(a)(ii)(C). 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 11(a)(ii)(C).

(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. The Pledged Debt pledged by such Pledgor hereunder has been duly authorized, authenticated or issued and delivered, is the legal, valid and binding obligation of the issuers thereof, is evidenced by one or more promissory notes (which notes have been delivered to the Collateral Trustee) and is not in default.

(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.

(g) All filings and other actions (including without limitation, actions necessary to obtain control of Collateral as provided in Section 9-106 of the UCC) necessary to perfect the security interest in the Collateral of such Pledgor created under this Agreement have been duly made or taken and are in full force and effect, and this Agreement creates in favor of the Collateral Trustee for the benefit of the holders of Junior Lien Obligations a valid and, together with such filings and other actions, perfected second priority security interest in the Collateral of such Pledgor, securing the payment of the Junior Lien Obligations, subject to Liens permitted in Section 11(a)(ii)(C).

(h) No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for (i) the grant by such Pledgor of the security interest granted hereunder or for the execution, delivery or performance of this Agreement by such Pledgor, (ii) the perfection

or maintenance of the security interest created hereunder (including the second priority nature of such security interest), except for the filing of financing and continuation statements under the UCC, which financing statements have been duly filed and are in full force and effect, and the actions described in Section 5 with respect to Security Collateral, which actions have been taken and are in full force and effect or (iii) the exercise by the Collateral Trustee of its voting or other rights provided for in this Agreement or the remedies in respect of the Collateral pursuant to this Agreement, except (A) as may be required in connection with the disposition of any portion of the Security Collateral by laws affecting the offering and sale of securities generally and (B) with respect to clause (iii) above, the limitations set forth in Section 3.3 of the Collateral Trust Agreement.

Section 8. Further Assurances. (a) Each Pledgor agrees that from time to time, at the expense of such Pledgor, such Pledgor will promptly execute and deliver, or otherwise authenticate, all further instruments and documents, and take all further action that may be necessary or desirable, or that the Collateral Trustee may reasonably request, in order to perfect and protect any pledge or security interest granted or purported to be granted by such Pledgor hereunder or to enable the Collateral Trustee to exercise and enforce its rights and remedies hereunder with respect to any Collateral of such Pledgor. Without limiting the generality of the foregoing, each Pledgor will promptly with respect to Collateral of such Pledgor: (i) if any such Collateral shall be evidenced by a promissory note or other instrument in an aggregate principal amount of one million dollars ($1,000,000) or greater, deliver and pledge to the Collateral Trustee hereunder such note or instrument duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance reasonably satisfactory to the Collateral Trustee; (ii) file such financing or continuation statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Collateral Trustee may reasonably request, in order to perfect and preserve the security interest granted or purported to be granted by such Pledgor hereunder; (iii) deliver and pledge to the Collateral Trustee for benefit of the holders of Junior Lien Obligations certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond powers executed in blank; (iv) take all action necessary to ensure that the Collateral Trustee has control of Collateral consisting of investment property as provided in Section 9-106 of the UCC; and (v) deliver to the Collateral Trustee evidence that all other action that the Collateral Trustee may deem reasonably necessary or desirable in order to perfect and protect the security interest created by such Pledgor under this Agreement has been taken.

(b) Each Pledgor hereby authorizes the Collateral Trustee to file one or more financing or continuation statements, and amendments thereto, including, without limitation, one or more financing statements indicating that such financing statements cover the Collateral described herein, in each case without the signature of such Pledgor. Notwithstanding the authorization provided to the Collateral Trustee in this Section 8(b), each Pledgor shall be responsible for filing (and in furtherance of such obligation, each Pledgor is hereby authorized to file) any and all financing statements or continuations thereof or amendments thereto and shall promptly furnish copies of the filed statements to the Collateral Trustee.

Section 9. Post-Closing Changes. Neither the Initial Pledgor nor any Additional Pledgor will, following the date on which it becomes bound by this Agreement, change its name,

type of organization, jurisdiction of organization, organizational identification number or location from those set forth in Section 7(a) without first giving at least 15 days’ prior written notice to the Collateral Trustee and taking all action required by the Collateral Trustee for the purpose of perfecting or protecting the security interest granted by this Agreement. Each Pledgor will hold and preserve its records relating to the Collateral and will permit representatives of the Collateral Trustee at any time during normal business hours to inspect and make abstracts from such records and other documents. If any Pledgor does not have an organizational identification number on the day it becomes bound by this Agreement and later obtains one, it will forthwith notify the Collateral Trustee of such organizational identification number.

(ii) Each Pledgor shall be entitled to receive and retain any and all dividends, interest and other distributions paid in respect of the Security Collateral of such Pledgor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Secured Debt Documents; provided, however, that any and all dividends, interest and other distributions paid or payable other than in cash in respect of, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Security Collateral, shall be, and shall be forthwith delivered to the Collateral Trustee to hold as, Security Collateral and shall, if received by such Pledgor, be received in trust for the benefit of the Collateral Trustee, be segregated from the other property or funds of such Pledgor and be forthwith delivered to the Collateral Trustee as Security Collateral in the same form as so received (with any necessary indorsement).

(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.

(b) Subject to the provisions of the Collateral Trust Agreement, upon the occurrence and during the continuance of an event of default under any Junior Lien Documents:

and all such rights shall thereupon become vested in the Collateral Trustee, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights and to receive and hold as Security Collateral such dividends, interest and other distributions.

(ii) All dividends, interest and other distributions that are received by any Pledgor contrary to the provisions of paragraph (i) of this Section 10(b) 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 as Security Collateral in the same form as so received (with any necessary indorsement).

Section 11. Transfers and Other Liens; Additional Shares. (a) Each Pledgor agrees that it will not (i) sell, assign or otherwise dispose of, or grant any option with respect to, any of the Collateral, other than sales, assignments and other dispositions of Collateral, and options relating to Collateral, permitted under the terms of the Indentures and documents governing other Junior Lien Debt, or (ii) create or suffer to exist any Lien upon or with respect to any of the Collateral of such Pledgor except for (A) the pledge, assignment and security interest created under this Agreement, (B) the pledge, assignment and security interest created in favor of the holders of Parity Lien Obligations and (C) Liens permitted under Section 4.12(b) of each of the Indentures.

Section 14. The Collateral Trustee’s Duties. (a) The powers conferred on the Collateral Trustee hereunder are solely to protect the holders of Junior 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 Junior 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.

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 Junior 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.

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.

No failure on the part of the Collateral Trustee or any other holder of Junior 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.

Section 5. The Issuer’s Responsibility. (a) The Issuer will not be liable to the Grantor or the Secured Party for complying with a Notice of Exclusive Control or with an Entitlement Order or other direction concerning the Uncertificated Security originated by the Secured Party, even if the Grantor notifies the Issuer that the Secured Party is not legally entitled to issue the Notice of Exclusive Control or Entitlement Order or such other direction unless the Issuer takes the action after it is served with an injunction, restraining order or other legal process enjoining it from doing so, issued by a court of competent jurisdiction, and had a reasonable opportunity to act on the injunction, restraining order or other legal process.

(b) This Agreement does not create any obligation of the Issuer except for those expressly set forth in this Agreement and in Part 5 of Article 8 of the N.Y. Uniform Commercial Code. In particular, the Issuer need not investigate whether the Secured Party is entitled under the Secured Party’s agreements with the Grantor to give an Entitlement Order or other direction concerning the Uncertificated Security or a Notice of Exclusive Control. The Issuer may rely on notices and communications it believes given by the appropriate party.

Section 6. Indemnity. The Grantor will indemnify the Issuer, its officers, directors, employees and agents against claims, liabilities and expenses arising out of this Agreement (including, without limitation, reasonable attorney’s fees and disbursements), except to the extent the claims, liabilities or expenses are caused by the Issuer’s gross negligence or willful misconduct as found by a court of competent jurisdiction in a final, non-appealable judgment.

Section 7. Termination; Survival. (a) The Secured Party may terminate this Agreement by notice to the Issuer and the Grantor. If the Secured Party notifies the Issuer that the Security Interest has terminated, this Agreement will immediately terminate.

Section 8. Governing Law. This Agreement is governed by and construed in accordance with the law of the State of New York.

Section 9. Entire Agreement. This Agreement is the entire agreement, and supersedes any prior agreements, and contemporaneous oral agreements, of the parties concerning its subject matter.

Aron & Company, as Posting Calculation Agent.

A. Grantor executed and delivered that certain Deed of Trust, Assignment of Leases and Rents, Security Agreement and Fixture Filing (as amended by this Amendment and as further amended, amended and restated, supplemented or otherwise modified from time to time, the “Deed of Trust”) dated as of October 10, 2007, to Fidelity National Title Insurance Company, Trustee, for the benefit of Beneficiary, covering certain real and personal property located in County, Texas, as more particularly described therein, save and except any portions of such real property that have been previously released from the Deed of Trust by Beneficiary (the “Mortgaged Property”), which Deed of Trust was recorded in the Real Property Records of County, Texas, [as Instrument No. ] [under Volume , Page ].

B. The Deed of Trust secures the payment and performance of the Obligations (as defined in the Deed of Trust), and Beneficiary is the Collateral Agent thereunder.

C. Pursuant to Amendment No. 2 to Credit Agreement, the maturity dates of certain of the Obligations are being extended, and the parties desire to amend the Deed of Trust to evidence of record the extended maturity date of the Obligations.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Grantor and Beneficiary hereby agree as follows:

1. Defined Terms. All capitalized terms used herein and not otherwise defined shall have the meaning given to that term in the Deed of Trust.

2. Amendments to Deed of Trust. The Deed of Trust is hereby amended as follows:

(a) Pursuant to Amendment No. 2 to Credit Agreement, the maturity date of certain of the Obligations has been extended to a date not later than October 10, 2017.

(b) Section 3.5 of the Deed of Trust is hereby amended by deleting such section in its entirety and replacing it with the following:

3.5 Insurance. Grantor will keep or cause to be kept the Mortgaged Property insured against such risks and shall purchase such additional insurance to the extent that is required from time to time pursuant to Section 9.3 of the Credit Agreement. Without limiting the generality of the foregoing, if any portion of the Mortgaged Property is located in an area identified by the Federal Emergency Management Agency as an area having special flood hazards and in which flood insurance has been made available under the National Flood Insurance Act of 1968 (or any amendment or successor act thereto), then Grantor shall maintain, or cause to be maintained, with a financially sound and reputable insurer, flood insurance in an amount sufficient to comply with all applicable rules and regulations promulgated pursuant to such Act.

(c) Section 16 of the Deed of Trust is hereby amended by deleting such section in its entirety and replacing it with the following:

(a) Beneficiary and Trustee shall be entitled to enforce payment and performance of the Obligations and to exercise all rights and powers under this Deed of Trust or under any of the other Security Documents or other agreement or any laws now or hereafter in force, notwithstanding some or all of the Obligations may now or hereafter be otherwise secured, whether by deed of trust, mortgage, security agreement, pledge, lien, assignment or otherwise. Neither the acceptance of this Deed of Trust nor its enforcement, shall prejudice or in any manner affect Beneficiary’s or Trustee’s right to realize upon or enforce any other security now or hereafter held by Beneficiary or Trustee, it being agreed that Beneficiary and Trustee shall be entitled to enforce this Deed of Trust and any other security now or hereafter held by Beneficiary or Trustee in such order and manner as Beneficiary or Trustee may determine in its absolute discretion. No remedy herein conferred upon or reserved to Trustee or Beneficiary is intended to be exclusive of any other remedy herein or by law provided or permitted, but each shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or by statute. Every power or remedy given by any of the Security Documents to Beneficiary or Trustee or to which either may otherwise be entitled, may be exercised, concurrently or independently, from time to time and as often as may be deemed expedient by Beneficiary or Trustee, as the case may be. In no event shall Beneficiary or Trustee, in the exercise of the remedies provided in this Deed of Trust (including, without limitation, in connection with the assignment of Rents to Beneficiary, or the appointment of a receiver and the entry of such receiver on to all or any part of the Mortgaged Property), be

deemed a “mortgagee in possession,” and neither Beneficiary nor Trustee shall in any way be made liable for any act, either of commission or omission, in connection with the exercise of such remedies.

(b) Without limiting the generality of Section 16(a), except as otherwise provided in Section 16(c) below, neither the enforcement of any of the remedies under Sections 5 and 16 hereof, the security interests under Section 9, the assignment of Rents under Section 10, nor any other remedies afforded to Beneficiary under the Security Documents, at law or in equity shall cause Beneficiary, any Lender or Trustee to be deemed or construed to be a mortgagee in possession of the Mortgaged Property, to obligate Beneficiary, any Lender or Trustee to lease the Mortgaged Property or attempt to do so, or to take any action, incur any expense, or perform or discharge any obligation, duty or liability whatsoever under any of the Leases or otherwise.

(c) Notwithstanding the provisions of Section 16(b) above, Beneficiary shall not obtain title to a deed in lieu of foreclosure or otherwise, or take any other action with respect to the Mortgaged Property, if, as a result of any such action, Beneficiary could, in its reasonable judgment be considered to hold title to, to be a “mortgagee-in-possession” of, or to be an “owner” or “operator” of the Mortgaged Property within the meaning of Comprehensive Environmental Response, Compensation and Liability Act Of 1980 (42 U.S.C. Sections 9601 et seq.), as amended, or any comparable law, unless:

(i) Beneficiary has previously and reasonably determined, based on a Phase I environmental site assessment (and any additional environmental testing that Beneficiary deems necessary and prudent) of such Mortgaged Property conducted by an independent third party who regularly conducts Phase I environmental site assessments and performed during the 12-month period preceding any such acquisition of title or other action, that the Mortgaged Property is in compliance with applicable environmental laws and regulations and there are no circumstances or conditions present at the Mortgaged Property relating to the use, management or disposal of Hazardous Materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any applicable environmental laws and regulations; or

(ii) in the event that the determination described in clause (i) above cannot be made, Beneficiary has previously and reasonably determined, on the same basis as described in clause (i) above, that it would maximize the recovery to the Secured Parties on a present value basis to acquire title to or possession of the Mortgaged Property and to take such remedial, corrective and/or other further actions as are necessary to bring the Mortgaged Property into compliance with applicable environmental laws and regulations and to appropriately address any of the circumstances and conditions referred to in clause (i) above.

(d) Beneficiary shall undertake, in good faith, reasonable efforts to make the determination referred to in clause (ii) above, and may conclusively rely on the Phase I environmental site assessment referred to above, and upon an opinion of counsel, in making such determination. The cost of any such Phase I environmental site assessment and any such opinion of counsel, and the cost of any Phase II environmental site assessment, additional environmental testing

and remedial, corrective or other further action contemplated by clause (i) or clause (ii) above, shall be paid at the sole expense of Grantor.

(e) If the environmental testing contemplated by Section 16(b) above establishes that any of the conditions set forth in clause (i) have not been satisfied with respect to the Mortgaged Property, Beneficiary shall take such action (other than proceeding against the Mortgaged Property) and, at such time as it deems appropriate, may release all or a portion of such Mortgaged Property from the lien of this Deed of Trust, provided that prior to the release of all or a portion of the Mortgaged Property from the lien of this Deed of Trust (a) Beneficiary shall have notified the Lenders in writing of its intention to so release all or a portion of such Mortgaged Property and (b) the holders of a majority of the outstanding principal balance of the Obligations shall not have objected to such release within thirty (30) days of the distribution of the last of such notices.

(d) Section 29 of the Deed of Trust is hereby amended by deleting such section in its entirety and replacing it with the following:

3. No Other Amendments. Except as amended hereby, the Deed of Trust is acknowledged to be in full force and effect as written. Nothing in this Amendment is intended to waive any rights or remedies of the Beneficiary under the Deed of Trust, or any defaults of Grantor under the Deed of Trust. The Deed of Trust shall continue to be a valid and subsisting lien against the Mortgaged Property. The Grantor, in order to continue to secure the payment of the Obligations, hereby confirms and restates [(a)] the conveyance pursuant to the Deed of Trust to the Beneficiary of the Mortgaged Property[ and (b) the grant pursuant to the Deed of Trust of a security interest in the Fixtures]. Nothing contained in this Amendment shall be construed as (a) a novation of the Obligations or (b) a release or waiver of all or any portion of the conveyance to the Beneficiary of the Mortgaged Property or the grant to the Beneficiary of a security interest in the Fixtures pursuant to the Deed of Trust.

4. No Oral Agreements. THIS WRITTEN AMENDMENT, TOGETHER WITH ALL OF THE OTHER LOAN DOCUMENTS AND THE AMENDMENTS THERETO, AS AMENDED HEREBY, REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

5. Multiple Counterparts. This Amendment may be executed in any number of counterparts, all of which taken together shall constitute one and the same agreement, and any of the parties to this Amendment may execute this Amendment by signing any of the counterparts.

6. Representations and Warranties. The Grantor hereby represents and warrants that the representations and warranties made by it in the Deed of Trust are true and complete on and as of the date hereof as if made on and as of the date hereof.

7. Covenants. The Grantor hereby covenants and agrees to perform each and every duty and obligation of the Grantor contained in the Deed of Trust as amended by this Amendment.

2010 Form 10-K		EFH Corp.’s Annual Report on Form 10-K for the year ended December 31, 2010

Adjusted EBITDA		Adjusted EBITDA means EBITDA adjusted to exclude noncash items, unusual items and other adjustments allowable under certain of our debt arrangements. See the definition of EBITDA below. Adjusted EBITDA and EBITDA are not recognized terms under GAAP and, thus, are non-GAAP financial measures. We are providing Adjusted EBITDA in this Form 10-Q (see reconciliations in Exhibits 99(b), 99(c) and 99(d)) solely because of the important role that Adjusted EBITDA plays in respect of certain covenants contained in our debt arrangements. We do not intend for Adjusted EBITDA (or EBITDA) to be an alternative to net income as a measure of operating performance or an alternative to cash flows from operating activities as a measure of liquidity or an alternative to any other measure of financial performance presented in accordance with US GAAP. Additionally, we do not intend for Adjusted EBITDA (or EBITDA) to be used as a measure of free cash flow available for management’s discretionary use, as the measure excludes certain cash requirements such as interest payments, tax payments and other debt service requirements. Because not all companies use identical calculations, our presentation of Adjusted EBITDA (and EBITDA) may not be comparable to similarly titled measures of other companies.

baseload		Refers to the minimum constant level of electricity demand in a system, such as ERCOT, and/or to the electricity generation facilities or capacity normally expected to operate continuously throughout the year to serve such demand, such as our nuclear and lignite/coal-fueled generation units.
