Energy Future Intermediate Holding Company LLC and EFIH Finance Inc.

Commence Offer for First Lien Notes Settlement

DALLAS – May 7, 2014 – Energy Future Intermediate Holding Company LLC (“EFIH”), a wholly-owned subsidiary of Energy Future Holdings Corp. (“EFH Corp.”), and EFIH Finance Inc. (together with EFIH, the “Issuer”) today commenced an offer to holders of the EFIH First Lien Notes (as defined below) to participate in a voluntary settlement with respect to the Issuer’s obligations under the EFIH First Lien Notes (such settlement, the “EFIH First Lien Settlement”). The EFIH First Lien Settlement is open to all qualified holders of the Issuer’s 6.875% Senior Secured Notes due 2017 and 10.000% Senior Secured Notes due 2020 (such notes, the “EFIH First Lien Notes”).

Pursuant to the Restructuring Support and Lock-Up Agreement, dated as of April 29, 2014, certain holders of EFIH First Lien Notes holding, in the aggregate, approximately 32% of the aggregate outstanding principal amount of EFIH First Lien Notes have agreed to the terms of the EFIH First Lien Settlement.

Upon the terms and subject to the conditions of the Information Memorandum for participation in the EFIH First Lien Settlement, each holder of EFIH First Lien Notes that validly tenders its EFIH First Lien Notes and delivers a duly executed Letter of Transmittal relating to its EFIH First Lien Notes prior to 5:00 p.m., New York City time, on May 19, 2014, unless extended by EFIH in its sole discretion (the “Early Participation Date”) will be eligible to receive on the closing date of the offer as payment in full of any claims arising out of its EFIH First Lien Notes, for each $1,000 principal amount of EFIH First Lien Notes validly tendered, $1,050.00 in aggregate principal amount of EFIH first lien term loans (the “EFIH First Lien DIP Loans”) under a new senior secured super-priority debtor-in-possession credit agreement (the “EFIH First Lien DIP Facility”) (such consideration, 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 $17.50 in an aggregate principal amount of EFIH First Lien DIP Loans per $1,000 principal amount of EFIH First Lien Notes validly tendered on or prior to the Early Participation Date. Holders that validly tender their EFIH First Lien Notes and deliver a duly executed Letter of Transmittal relating to their EFIH First Lien Notes after the Early Participation Date and prior to the Expiration Date (as defined below) will be eligible to receive on the closing date of the offer an amount of EFIH First Lien DIP Loans equal to the Total Consideration less the Early Participation Consideration per $1,000 principal amount of EFIH First Lien Notes (the “Exchange Consideration” as set forth in the table below). The offer period for the EFIH First Lien Settlement will expire at 5:00 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 First Lien Settlement to expire prior to the date the EFIH First Lien Settlement is heard, and approved, by the bankruptcy court.

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

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

All EFIH First Lien Notes that are not exchanged for EFIH First Lien DIP Loans pursuant to the offer to participate in the EFIH First Lien Settlement will, upon receipt of all necessary bankruptcy court approvals and consummation of the EFIH First Lien DIP Facility, be repaid in full in an amount equal to all outstanding principal plus accrued and unpaid interest at the non-default rate due and owing under the EFIH First Lien Notes (which will not include any alleged premiums, settlements, fees or claims relating to repayment of such claims). Notwithstanding the EFIH First Lien Settlement, EFH Corp., EFIH and EFIH Finance, among others, intend to initiate 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 payments provisions under the EIFH First Lien Notes.
