Item 1.01      Entry into a Material Definitive Agreement.

Reference is made to the Current Reports on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on (a) April 1, 2011, by each of EFH Corp., EFCH and EFIH regarding the commencement of solicitation of consents by Texas Competitive Electric Holdings Company LLC (“TCEH”), a subsidiary of EFH Corp. and EFCH, from lenders (the “Lenders”) under its Credit Agreement, dated as of October 10, 2007 (as amended, the “Senior Secured Credit Facilities”), for an amendment to the Senior Secured Credit Facilities (the “Amendment”) and the extension of certain loans and commitments under the Senior Secured Credit Facilities (the “Extension” and, together with the Amendment, the “Credit Facilities Amendment”); (b) April 8, 2011, by each of EFH Corp., EFCH and EFIH regarding the receipt of the requisite consents from Lenders in order for the Amendment to become effective, the execution of the Amendment by the requisite parties and the effectiveness of the Amendment; (c) April 13, 2011, by each of EFH Corp. and EFCH regarding the agreement by Lenders to extend the maturity of over 80% of the aggregate amount of the outstanding term loans and deposit letter of credit loans under the Senior Secured Credit Facilities pursuant to the Extension, and the agreement by Lenders to extend a certain portion of their commitments under the TCEH revolving credit facility pursuant to the Extension; (d) April 14, 2011, by each of EFH Corp. and EFCH regarding the commencement of an offering of senior secured notes by TCEH and TCEH Finance, Inc., a wholly-owned subsidiary of TCEH (collectively, the “Issuer”); and (e) April 14, 2011, by each of EFH Corp. and EFCH regarding the pricing of such senior secured notes.

Senior Secured Credit Facilities

As previously disclosed, the Amendment became effective on April 7, 2011. The Amendment includes, among other things, amendments to certain covenants contained in the Senior Secured Credit Facilities (including the Consolidated Secured Debt to Consolidated EBITDA Ratio (as such term is defined in the Senior Secured Credit Facilities) financial maintenance covenant), as well as an acknowledgement from the Lenders that (i) the terms of the Intercompany Notes (as defined below) comply with the Senior Secured Credit Facilities, including the requirement that these loans be made on an “arm’s-length” basis, and (ii) no mandatory repayments relating to excess cash flows were required to be made by TCEH under the Senior Secured Credit Facilities for fiscal years 2008, 2009 and 2010.

In addition, the Amendment 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”). In addition to the acknowledgement described above, TCEH agreed in the Amendment:

Further, in connection with the Amendment, the following actions were taken with respect to the Intercompany Notes:

TCEH also repaid all borrowings outstanding under its note payable to EFH Corp.

Although the Amendment became effective on April 7, 2011, the closing and effectiveness of the Extension was conditioned upon the satisfaction of certain conditions, including, among others, (a) the closing of an offering of senior secured notes (unless waived by TCEH) and (b) the aggregate pro-rata repayment of certain outstanding loans under the Senior Secured Credit Facilities and, solely with respect to the extended commitments under the revolving credit facility, the reduction of certain commitments under the revolving credit facility. On April 19, 2011, the Issuer issued $1,750 million aggregate principal amount of 11.5% Senior Secured Notes due 2020 (the “New Notes”) at 99.295% of face value and used the net proceeds from the issuance of the New Notes to repay approximately $1.6 billion aggregate principal amount of loans under the Senior Secured Credit Facilities and to pay certain arranger fees and expenses to the initial purchasers of the New Notes related to the Credit Facilities Amendment. As a result, the Extension became effective on April 19, 2011.

As a result of the Extension becoming effective, under the Senior Secured Credit Facilities there are approximately:

The interest rate on the extended term loans and extended deposit letter of credit loans increased from LIBOR plus 3.50% to LIBOR plus 4.50%. The interest rate on the extended revolving commitments increased from LIBOR plus 3.50% to LIBOR plus 4.50%, and the undrawn fee with respect to such commitments increased from 0.50% to 1.00%. 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 to Lenders that agreed to extend their term loans and deposit letter of credit loans.

The Senior Secured Credit Facilities include a “springing maturity” provision pursuant to which (a) in the event that more than $500 million aggregate principal amount of TCEH’s 10.25% Senior Notes due 2015 and 10.25% Senior Notes due 2015, Series B (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 TCEH’s 10.50%/11.25% Senior Toggle Notes due 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 Senior Secured Credit 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.

A copy of the Senior Secured Credit Facilities, as amended by the Credit Facilities Amendment, is attached hereto as Exhibit 10.1 and is incorporated herein by reference. The description of the Credit Facilities Amendment and the Senior Secured Credit Facilities herein is qualified in its entirety by reference to the Senior Secured Credit Facilities.

Indenture

On April 19, 2011, the Issuer entered into an indenture (the “Indenture”) among the Issuer, the guarantors party thereto (collectively, the “Guarantors”) and The Bank of New York Mellon Trust Company, N.A., as trustee. Pursuant to the Indenture, the Issuer issued $1,750 million aggregate principal amount of New Notes. The New Notes will mature on October 1, 2020. Interest on the New Notes is payable in cash quarterly in arrears on January 1, April 1, July 1 and October 1 of each year at a fixed rate of 11.5% per annum, commencing on July 1, 2011.

The New Notes are initially unconditionally guaranteed (the “guarantees”) on a senior basis, jointly and severally, by the Guarantors, which are the same guarantors that guarantee the obligations arising under the Senior Secured Credit Facilities. The New 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 of all of the Guarantors, in each case, to the extent such assets and equity interests secure obligations under the Senior Secured Credit Facilities (the “Collateral”), subject to certain exceptions and permitted liens.

The New Notes and the guarantees are senior obligations of the Issuer and the Guarantors, respectively, and rank equally in right of payment with all existing and future senior debt of the Issuer and the Guarantors, respectively. The New Notes and the guarantees are effectively subordinated to the Issuer’s and the Guarantors’ existing and future debt that is secured by assets that are not a part of the Collateral, to the extent of the value of such assets. The New Notes are structurally subordinated to all existing and future debt and liabilities of TCEH’s non-guarantor subsidiaries (other than TCEH Finance, Inc.). The New Notes and the guarantees are effectively senior in right of payment to all existing and future second-priority and unsecured debt of the Issuer and the Guarantors to the extent of the value of the Collateral. The New Notes and the guarantees are senior in right of payment to any future subordinated debt of the Issuer and the Guarantors, respectively.

The New Notes and the Indenture restrict TCEH’s and its restricted subsidiaries’ ability to, among other things:

These covenants are subject to a number of important 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 or the guarantees when due.

The Issuer may redeem the New Notes, in whole or in part, at any time on or after April 1, 2016, at specified redemption prices, plus accrued and unpaid interest, if any. In addition, before April 1, 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 111.500% 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 April 1, 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 were offered only to “qualified institutional buyers” as defined under Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act. The New Notes have not been registered under 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. The Issuer and the Guarantors are not required to, nor do they intend to, register the New Notes for resale under the Securities Act or the securities laws of any other jurisdiction or to offer to exchange the New Notes for registered notes under the Securities Act or the securities laws of any other jurisdiction.

In addition, in connection with the issuance of the New Notes, TCEH and certain subsidiary guarantors of the New Notes have entered into separate Subordination and Priority Agreements with respect to each property secured by a deed of trust with Citibank, N.A., as beneficiary under the First Lien Credit Deed of Trust, and The Bank of New York Mellon Trust Company, N.A., as beneficiary under the Second Lien Indenture Deed of Trust, and Citibank, N.A., as beneficiary under the First Lien Indenture Deed of Trust (as each term is defined in each Subordination and Priority Agreement) to establish certain priorities with respect to collateral under their respective financing documents. Each Subordination and Priority Agreement has been executed and filed of record or will be filed of record in the appropriate counties.
