11.250%/12.000% Senior Toggle Notes due 2017 and

10.875% Senior Notes due 2017 of

EFH Corp. and

Related Consent Solicitation

DALLAS – July 16, 2010 – Energy Future Holdings Corp. (“EFH Corp.”) announced today that its direct, wholly-owned subsidiary, Energy Future Intermediate Holding Company LLC (“EFIH”), and EFIH’s direct, wholly-owned subsidiary, EFIH Finance Inc. (“EFIH Finance” and, together with EFIH, the “Offerors”), are commencing exchange offers (the “Exchange Offers”) to exchange the outstanding 11.250%/12.000% Senior Toggle Notes due 2017 and 10.875% Senior Notes due 2017 of EFH Corp. (collectively, the “Old Notes”) for up to $2.18 billion aggregate principal amount of 10.000% Senior Secured Notes due 2020 to be issued by the Offerors (the “New Senior Secured Notes”) and an aggregate of $500 million in cash, upon the terms and subject to the conditions set forth in the prospectus relating to the Exchange Offers (the “Prospectus”) and the related Consent and Letter of Transmittal. The maximum aggregate principal amount of New Senior Secured Notes issuable in the Exchange Offers, which is referred to herein as the “Maximum Exchange Amount,” will not exceed $2.18 billion.

The purpose of the Exchange Offers is to reduce the outstanding principal amount, reduce interest expense and extend the weighted average maturity, of the long-term debt of EFH Corp. and its subsidiaries.

Concurrent with the Exchange Offers, and upon the terms and subject to the conditions more fully described in the Prospectus and the related Consent and Letter of Transmittal, EFH Corp. is soliciting (the “Consent Solicitation”) consents (the “Consents”) from holders of Old Notes to certain proposed amendments (the “Proposed Amendments”) to the indenture pursuant to which the Old Notes were issued. The Proposed Amendments are summarized below.

On July 15, 2010, EFH Corp., EFIH and EFIH Finance entered into exchange agreements with certain institutional investors that are holders of certain of the Old Notes, pursuant to which such holders agreed to participate in the Exchange Offers and the Consent Solicitation. EFH Corp. and the Offerors expect that such holders will tender and deliver consents in respect of approximately $2.3 billion aggregate principal amount of Old Notes, representing approximately 52% of the aggregate principal amount of outstanding Old Notes, in the Exchange Offers and the Consent Solicitation pursuant to these agreements. As a result of these agreements to participate in the Exchange Offers and the Consent Solicitation, it is expected that no additional Old Notes would need to be validly tendered (and not validly withdrawn) in the Exchange Offers or related Consents validly delivered (and not validly revoked) in the Consent Solicitation for the minimum condition to the Exchange Offers to be satisfied and to obtain the requisite Consents to adopt the Proposed Amendments.

Upon the terms and subject to the conditions of the Exchange Offers, including the Maximum Exchange Amount and the prorations, if necessary, resulting therefrom, in exchange for each $1,000 principal amount of Old Notes validly tendered (and not validly withdrawn), the participating holders of Old Notes will be eligible to receive, the following:

1

The aggregate amount of cash payable as the aggregate Total Cash Consideration in the Exchange Offers is $500 million, which amount may be reduced as a result of proration, if any, or withdrawals after the Early Tender Date of Old Notes previously validly tendered (and not validly withdrawn) at or prior to the Early Tender Date. The potential reduction of this cash amount will not change the amount of Total Cash Consideration to be paid in exchange for each $1,000 principal amount of Old Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Date and that will be announced by

2

press release promptly after the Early Tender Date and in any event at least ten business days prior to (and including) the Expiration Date. This aggregate amount of cash will be paid as the Total Cash Consideration in exchange for Old Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Date and accepted for exchange such that each 10.875% Senior Note due 2017 of EFH Corp. (the “Old Cash-Pay Notes”) and each 11.250%/12.000% Senior Toggle Note due 2017 of EFH Corp. (the “Old Toggle Notes”) validly tendered (and not validly withdrawn) at or prior to the Early Tender Date and accepted for exchange will receive the same percentage of its Total Consideration Amount in cash. The portion of the Total Consideration Amount paid in cash will correspondingly reduce on a dollar basis the principal amount of the Total Consideration Amount for each issue of Old Notes that is comprised of Total Notes Consideration.

The Offerors will not accept any tender of Old Notes that would result in the issuance of less than $2,000 principal amount of New Senior Secured Notes to a participating holder. Furthermore, the aggregate principal amount of New Senior Secured Notes issued to each participating holder for all Old Notes validly tendered (and not validly withdrawn) will be rounded down, if necessary, to $2,000 or the nearest whole multiple of $1,000 in excess thereof. The rounded amount will be the principal amount of New Senior Secured Notes a participating holder will receive, and no additional cash will be paid in lieu of any principal amount of New Senior Secured Notes not received as a result of such rounding down.

At the time of the commencement of the Exchange Offers, the Total Consideration Amount for the Old Cash-Pay Notes equals the minimum Total Cash Consideration of $146.46 per $1,000 principal amount of Old Cash-Pay Notes and the maximum Total Notes Consideration of $638.54 principal amount of New Senior Secured Notes payable per $1,000 principal amount of Old Cash-Pay Notes, which amounts would be payable if all of the Old Notes were tendered at or prior to the Early Tender Date and Old Notes are accepted for exchange. At the time of the commencement of the Exchange Offers, the Total Consideration Amount for the Old Toggle Notes equals the minimum Total Cash Consideration of $134.33 per $1,000 principal amount of Old Toggle Notes and the maximum Total Notes Consideration of $585.67 principal amount of New Senior Secured Notes payable per $1,000 principal amount of Old Toggle Notes, which amounts would be payable if all of the Old Notes were tendered at or prior to the Early Tender Date and Old Notes are accepted for exchange. The definitive amount of the Total Notes Consideration and the Total Cash Consideration per $1,000 principal amount of Old Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Date and accepted for exchange will be announced by press release promptly after the Early Tender Date and in any event at least ten business days prior to (and including) the Expiration Date.

1. Terms of the Consent Solicitation

a. The Consent Solicitation

EFH Corp. is soliciting Consents with respect to the Indenture, dated as of October 31, 2007, by and among EFH Corp., the guarantors named therein and The Bank of New York Mellon Trust Company, N.A., as trustee, pursuant to which the Old Notes were issued, as amended and supplemented (the “Old Notes Indenture”).

Old Notes validly tendered pursuant to the Exchange Offers (and not validly withdrawn) at or prior to the Consent Date will be deemed to include Consents to the Proposed Amendments. Holders may not validly tender Old Notes in the Exchange Offers at or prior to the Consent Date without delivering the related Consents in the Consent Solicitation, but holders may tender Old Notes after the Consent Date and at or prior to the Expiration Date without delivering Consents with respect to such Old Notes. However, holders tendering Old Notes after the Early Tender Date will not be eligible to receive the applicable Total Consideration Amount for such Old Notes, including the Total Cash Consideration, or the cash consent payment described below. Likewise, holders of Old Notes may not deliver Consents in the Consent Solicitation without validly tendering their Old Notes in the Exchange Offers at or prior to the Consent Date and may only validly revoke Consents by validly withdrawing the previously tendered related Old Notes at or prior to the Consent Date or by revoking Consents after the Consent Date and prior to the execution of the supplemental indenture.

b. Proposed Amendments; Waiver

The Proposed Amendments would eliminate substantially all of the restrictive covenants contained in the Old Notes Indenture and the Old Notes, eliminate certain events of default, modify covenants regarding mergers and consolidations and modify or eliminate certain other provisions, including certain provisions relating to defeasance contained in the Old Notes Indenture and the Old Notes that would otherwise prevent a defeasance without, among other things, delivery of an opinion of counsel confirming such defeasance does not constitute a taxable event. In addition to the foregoing, execution and delivery of the Consent and Letter of Transmittal will constitute an express waiver by a consenting holder of the Old Notes with respect to all claims against EFH Corp., the guarantors of the Old Notes and certain affiliates of EFH Corp. of any breach, default or event of default that may have arisen under the Old Notes Indenture.

c. Requisite Consents

In order to be adopted with respect to the Old Notes, the applicable Proposed Amendments must be consented to by the holders of at least a majority of the outstanding aggregate principal amount of the Old Notes, voting together as a single class. EFH Corp. will pay cash consideration for Consents as described below.

d. Consent Date

To deliver Consents pursuant to the Consent Solicitation, holders must validly tender (and not validly withdraw) their Old Notes, and thereby deliver Consents related to such Old Notes, at or prior to 5:00 p.m., New York City time, on July 29, 2010 (such time and date, as the same may be extended by EFH Corp., the “Consent Date”). If the requisite Consents are received and a supplemental indenture for the Old Notes is executed, EFH Corp. will pay to each holder, in respect of such holder’s Old Notes as to which Consents are validly delivered and not validly revoked at or prior to the Consent Date, a cash consent payment of $2.50 per $1,000 principal amount of such Old Notes. Such consent payment is in addition to any Total Consideration Amount or Exchange Consideration that may be payable to a holder in respect of its Old Notes accepted for exchange. Consent payments are not subject to proration. EFH Corp.’s obligation to make consent payments is not conditioned upon completion of the Exchange Offers but is subject to receipt of the requisite Consents and execution and delivery of the related supplemental indenture. If the Exchange Offers are terminated, the Proposed Amendments in any executed supplemental indenture will not become operative.

2. Terms of the Exchange Offers

a. Maximum Exchange Amount

The maximum aggregate principal amount of New Senior Secured Notes issuable in the Exchange Offers will not exceed $2.18 billion. Subject to applicable law, the Offerors reserve the right, but are not obligated, to increase or decrease the Maximum Exchange Amount. The terms of the Exchange Offers are described more fully in the Prospectus and the related Consent and Letter of Transmittal.

b. Early Tender Date

Upon the terms and subject to the conditions of the Exchange Offers described in the Prospectus, including the Maximum Exchange Amount and the prorations, if necessary, resulting therefrom, (i) participating holders who validly tender (and do not validly withdraw) their Old Notes at or prior to 5:00 p.m., New York City time, on July 29, 2010 (such time and date, as it may be extended by the

4

Offerors, the “Early Tender Date”) and whose Old Notes are accepted by the Offerors in the Exchange Offers will be eligible to receive the applicable consideration set forth in the table above under the heading “Total Consideration Amount if Tendered At or Prior to the Early Tender Date” in respect of each $1,000 principal amount of Old Notes accepted for exchange, and (ii) participating holders who validly tender their Old Notes after the Early Tender Date and at or prior to the Expiration Date and whose Old Notes are accepted by the Offerors in the Exchange Offers will be eligible to receive the applicable consideration set forth in the table above under the heading “Exchange Consideration if Tendered After the Early Tender Date and At or Prior to the Expiration Date” in respect of each $1,000 principal amount of Old Notes accepted for exchange. No cash consideration will be payable with respect to Old Notes that are validly tendered after the Early Tender Date.

c. Withdrawal Rights; Revocation Rights

A holder may withdraw the tender of such holder’s Old Notes at any time prior to the Expiration Date (and, if not previously accepted for exchange, after the expiration of 40 business days from July 16, 2010) as set forth in the Prospectus. The withdrawal of any Old Notes at or prior to the Consent Date will constitute a revocation of the related Consents. Consents may not be validly revoked prior to the Consent Date except by validly withdrawing the previously tendered Old Notes at or prior to the Consent Date. Consents may be validly revoked after the Consent Date by revoking such Consents prior to the execution and delivery of the supplemental indenture relating to the Proposed Amendments. Any Consents that are not validly revoked at or prior to the later of the Consent Date and the execution and delivery of such supplemental indenture may not be revoked thereafter.

d. Expiration Date

The Exchange Offers for the Old Notes will expire at midnight, New York City time, on August 12, 2010 (such time and date, as it may be extended by the Offerors, the “Expiration Date”).

3. Important Information Regarding the New Senior Secured Notes

a. Accrued Interest

The New Senior Secured Notes will accrue interest at the rate of 10.000% per annum from and including the settlement date for the Exchange Offers. Interest on the New Senior Secured Notes is payable on June 1 and December 1 of each year, commencing on December 1, 2010. Holders who receive New Senior Secured Notes in exchange for their Old Cash-Pay Notes will also receive, with respect to any such Old Cash-Pay Notes accepted for exchange, an amount equal to accrued and unpaid interest, if any, in cash, from the last applicable interest payment date to, but not including, the settlement date. Holders who receive New Senior Secured Notes in exchange for their Old Toggle Notes will not separately receive any accrued and unpaid payment-in-kind interest with respect to any of their Old Toggle Notes accepted for exchange because the amount of such accrued interest through the anticipated settlement date for the Exchange Offers has been included in determining the consideration being offered in the Exchange Offers for the Old Toggle Notes. If the settlement date occurs later than August 17, 2010, then the consideration being offered in the Exchange Offers for the Old Toggle Notes will be adjusted to account for the additional interest accrued after such date to, but not including, the settlement date.

b. Guarantees and Security

The New Senior Secured Notes will not be guaranteed. However, the New Senior Secured Notes will be secured by the Collateral (as defined in the Prospectus) on a first priority lien basis, equally and ratably with the 9.75% Senior Secured Notes due 2019 of EFIH and EFIH Finance and EFIH’s guarantees of the 9.75% Senior Secured Notes due 2019 of EFH Corp. and the 10.000% Senior Secured Notes due 2020 of EFH Corp.

4. Conditions to the Exchange Offers

The Exchange Offers are conditioned on at least a majority of the outstanding aggregate principal amount of Old Notes being validly tendered (and not validly withdrawn) at or prior to the Expiration Date. The Exchange Offers and the Consent Solicitation are also subject to the satisfaction or waiver of a number of other conditions as set forth in the Prospectus, including the condition applicable to the Exchange Offers (which condition cannot be waived) that the Registration Statement (as defined below), of which the Prospectus forms a part, has been declared effective by the Securities and Exchange Commission (“SEC”). Subject to applicable law, the Offerors have the right to terminate or withdraw the Exchange Offers and EFH Corp. has the right to terminate or withdraw the Consent Solicitation, at any time and for any reason, including if any of the conditions described in the Prospectus are not satisfied or waived by the Expiration Date or Consent Date, as applicable.

5. Additional Information

The Offerors filed a registration statement on Form S-4 (as it may be amended from time to time, the “Registration Statement”) relating to the Exchange Offers and the Consent Solicitation with the SEC on July 16, 2010. The Registration Statement has not yet become effective and the New Senior Secured Notes may not be issued, nor may the Exchange Offers be completed, until such time as the Registration Statement has been declared effective by the SEC and is not subject to a stop order or any proceedings for that purpose.

We urge holders to read the Prospectus relating to the Exchange Offers and the Consent Solicitation prior to making a decision to tender any of their Old Notes or otherwise make an investment decision with respect to the New Senior Secured Notes because it contains important information regarding the Exchange Offers and the Consent Solicitation.
