Energy Future Intermediate Holding Company LLC and

EFIH Finance Inc. Commence Cash Tender Offer for Second Lien Notes in

Connection with Second Lien Notes Settlement

DALLAS—May 9, 2014—Energy Future Intermediate Holding Company LLC (“EFIH”), a wholly-owned subsidiary of Energy Future Holdings Corp. (“EFH Corp.”), and EFIH Finance Inc. (“EFIH Finance” and together with EFIH, the “Issuer”) today commenced an offer to purchase EFIH Second Lien Notes (as defined below) for cash as a voluntary settlement with respect to the Issuer’s obligations under the EFIH Second Lien Notes (such settlement, the “EFIH Second Lien Settlement”). The EFIH Second Lien Settlement is open to all holders of the Issuer’s 11% Senior Secured Second Lien Notes due 2021 (the “EFIH 11% Second Lien Notes”) and 11.750% Senior Secured Second Lien Notes due 2022 (the “EFIH 11.750% Second Lien Notes” and together with the EFIH 11% Second Lien Notes, the “EFIH Second Lien Notes”).

Pursuant to that certain Restructuring Support and Lock-Up Agreement, dated as of April 29, 2014, certain holders of EFIH Second Lien Notes holding, in the aggregate, approximately 35% of the aggregate outstanding principal amount of EFIH Second Lien Notes have agreed to a voluntary settlement with respect to the Issuer’s obligations under the EFIH Second Lien Notes.

Upon the terms and subject to the conditions of the offer to purchase with respect to the EFIH Second Lien Settlement, each holder of EFIH Second Lien Notes that validly tenders its EFIH Second Lien Notes on or prior to 5:00 p.m., New York City time, on May 23, 2014, unless extended by EFIH at its sole discretion (the “Early Participation Date”) will be eligible to receive on the closing date of the offer (the “Settlement Date”) as payment in full of any claims arising out of such holder’s interest in the Second Lien Notes an amount, paid in cash, equal to (i) $1,123.22 for each $1,000 principal amount of EFIH 11% Second Lien Notes and (ii) $1,166.22 for each $1,000 principal amount of EFIH 11.750% Second Lien Notes tendered based on an assumed Settlement Date of June 11, 2014, which amounts will be decreased in each case by $0.14 for each day after June 11, 2014 that the Settlement Date occurs (such amount as may be reduced, the “Total Consideration” as set forth in the table below). The Total Consideration includes an early participation payment (the “Early Participation Consideration” as set forth in the table below) of $50.00 per $1,000 principal amount of EFIH Second Lien Notes validly tendered on or prior to the Early Participation Date. Each holder that validly tenders its EFIH Second Lien Notes after the Early Participation Date and on or prior to the Expiration Date (as defined below) will be eligible to receive on the Settlement Date an amount, paid in cash, equal to the Total Consideration less the Early Participation Consideration (the “Tender Consideration” as set forth in the table below).

The offer period for the EFIH Second Lien Settlement will expire at 11:59 p.m., New York City time, on June 6, 2014 (the “Expiration Date”), unless extended or earlier terminated by the Issuer in its sole discretion. The Issuer does not intend to permit the offer period for the EFIH Second Lien Settlement to expire prior to the date the EFIH Second Lien Settlement is heard, and approved, by the bankruptcy court.

In connection with the offer, the Issuer expects to obtain new debt financing through the issuance of approximately $1.9 billion of 8% Convertible Second Lien Subordinated Secured DIP Financing Notes due 2016 (the “EFIH Second Lien DIP Notes Financing”). The Tender Consideration, the Early Participation Consideration and the fees and expenses of the offer are expected to be paid with the proceeds of the EFIH Second Lien DIP Notes Financing and, if necessary, with cash on hand. The EFIH Second Lien DIP Notes Financing will not be registered under the Securities Act of 1933 or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.

The consummation of the EFIH Second Lien Settlement is subject to several conditions, including, among others, the closing of the EFIH Second Lien DIP Notes Financing, which is also subject to several conditions. The EFIH Second Lien Settlement will not be consummated unless, among other things, the bankruptcy court approves the EFIH Second Lien DIP Notes Financing and the EFIH Second Lien Settlement.

A holder that participates in the EFIH Second Lien Settlement will be required to tender all of its EFIH Second Lien Notes. No holder is required to participate in the EFIH Second Lien Settlement, and any holder’s participation is voluntary. The EFIH Second Lien Settlement is not conditioned on any minimum participation of holders of EFIH Second Lien Notes in the offer. Subject to applicable law, the Issuer reserves the right to terminate, withdraw or amend the right to participate in the EFIH Second Lien Settlement.

All EFIH Second Lien Notes that are not tendered pursuant to the offer to participate in the EFIH Second Lien Settlement will, upon receipt of all necessary bankruptcy court approvals and consummation of the EFIH Second Lien DIP Notes Financing, be repaid in full in an amount equal to all outstanding principal plus accrued and unpaid interest up to but not including the consummation of the EFIH Second Lien DIP Notes Financing at the non-default rate due and owing under the EFIH Second Lien Notes (which will not include any alleged premiums, settlements, fees or claims relating to repayment of such claims). Unless otherwise ordered by the bankruptcy court, accrued and unpaid interest will not include any additional interest payable under the registration rights agreement entered into in connection with the issuance of the EFIH 11.750% Second Lien Notes or interest on overdue interest following a default in the payment of interest on an interest payment date. Notwithstanding the EFIH Second Lien Settlement, EFH Corp., EFIH and EFIH Finance, among others, intend to initiate (if necessary) litigation to obtain entry of an order from the bankruptcy court disallowing any and all claims derived from, or based upon, makewhole or other similar payment provisions under the EIFH Second Lien Notes.
