Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrants under any of the following provisions (see General Instruction A.2. below):

Reference is made to the Current Reports on Form 8-K filed on April 1, 2011 and April 8, 2011, by each of Energy Future Holdings Corp. (“EFH Corp.”) and Energy Future Competitive Holdings Company (“EFCH”) regarding the 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 such credit facilities (the “Amendment”) and the extension of certain loans and commitments under such credit facilities (the “Extension”). On April 7, 2011, TCEH received the requisite consents from Lenders in order for the Amendment to become effective. As a result, the Amendment was executed by the requisite parties and became effective.

Pursuant to the Extension, TCEH offered all of its lenders under the TCEH Senior Secured Credit Facilities the right to extend:

(1) the maturity of TCEH’s first lien term loans held by accepting lenders (the “Extended Term Loans”) from October 10, 2014 to October 10, 2017 and increase the interest rate with respect to the Extended Term Loans from the London Interbank Offered Rate (“LIBOR”) plus 3.50% to LIBOR plus 4.50%;

(2) the maturity of TCEH’s first lien deposit letter of credit loans held by accepting lenders (the “Extended LC Loans”) from October 10, 2014 to October 10, 2017 and increase the interest rate with respect to the Extended LC Loans from LIBOR plus 3.50% to LIBOR plus 4.50%; and

(3) the maturity of the commitments under the revolving credit facility held by accepting lenders (the “Extended Revolving Commitments” and, together with the Extended Term Loans and the Extended LC Loans, the “Extended Loans”) from October 10, 2013 to October 10, 2016 and increase the interest rate with respect to the Extended Revolving Commitments from LIBOR plus 3.50% to LIBOR plus 4.50% and increase the undrawn fee with respect to such commitments from 0.50% to 1.00%.

Lenders agreed to extend the maturity of over 80% of the aggregate amount of the outstanding term loans and deposit letter of credit loans under the TCEH Senior Secured Credit Facilities, and Lenders agreed to extend a substantial portion of their commitments under the TCEH revolving credit facility. As a result, if the conditions to the effectiveness of the Extension are met (including the pro-rata repayment of loans and reduction of commitments as described in more detail below) and the Extension becomes effective as contemplated, there will be approximately:

The Extended Loans will 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 (as each term is defined in the Senior Secured Credit Facilities) ratio 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.

The closing and effectiveness of the Extension is 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 Revolving Commitments, the reduction of certain commitments under the revolving credit facility. The extension of the term loans and deposit letter of credit loans will not be conditioned upon the effectiveness of the extension of the commitments under the revolving credit facility. If the Extension becomes effective, TCEH will pay an up-front extension fee of 350 basis points to lenders holding Extended Term Loans and Extended LC Loans.
