     All of the information contained in Item 5 of this Form 8-K is being filed
by TXU Corp. Certain information contained in Item 5 of this Form 8-K relates to
TXU US Holdings Company (US Holdings), TXU Energy Company LLC (TXU Energy)
and/or TXU Gas Company (TXU Gas), wholly owned subsidiaries of TXU Corp. Such
information in Item 5 of this Form 8-K that relates to each of US Holdings, TXU
Energy and TXU Gas is being filed separately by each such registrant.

ITEM 5.  OTHER EVENTS AND REGULATION FD DISCLOSURE

     TXU Corp. today announced a series of transactions totaling approximately
$8 billion: the sale of TXU Australia, the sale of TXU Fuel Company (TXU Fuel),
TXU Corp.'s intent to sell TXU Gas and the repurchase by TXU Corp. of TXU
Energy's Exchangeable Preferred Membership Interests.

    Sale of TXU Australia
    ---------------------

     The largest transaction involves the sale of TXU Australia to Singapore
Power for an enterprise value of $3.72 billion. This results in a reduction of
$1.7 billion in consolidated TXU Corp. debt and proceeds to TXU Corp. of
approximately $1.8 billion after taxes and transaction costs. The transaction is
to be cleared by the Australian Competition and Consumer Commission. The sale is
expected to close in the third quarter. The pre-tax gain related to the sale is
expected to be approximately $375 million.

     Sale of TXU Fuel
     ----------------

     TXU Corp. has agreed to sell the assets of TXU Fuel, the gas transportation
subsidiary of TXU Energy with approximately 1,900 miles of intrastate pipeline
and a total system capacity of 1.3 Bcf/day, to Energy Transfer Partners, L.P.
for $502 million. As part of the transaction, TXU Energy will have an eight year
transportation agreement with the new owner to transport gas to TXU Energy's
generating assets. The transaction is expected to close on June 1, 2004, subject
to review under the federal Hart-Scott-Rodino Act. The pre-tax gain related to
the sale is expected to be approximately $390 million, which will be recognized
over eight years.

     TXU Corp. to Exit TXU Gas Business
     ----------------------------------

     TXU Corp. also intends to sell TXU Gas. TXU Gas is comprised of the
regulated natural gas transmission and distribution business in Texas. It is
expected that any transaction would be closed by the end of the year.

     Repurchase of TXU Energy's Preferred Membership Interests
     ---------------------------------------------------------

     TXU Corp. repurchased all $750 million outstanding principal amount of TXU
Energy's Exchangeable Preferred Membership Interests at a price of $1.842
billion. The repurchase closed on April 26, 2004 and will result in the
elimination of $750 million of 9% securities and 57.1 million diluted common
shares outstanding, as well as annual savings of $54 million in preferred
membership interest distributions. The transaction will also result in a
reduction in additional paid-in capital of approximately $815 million. This
amount represents the excess of the $1.842 billion repurchase amount over the
carrying amount of the security, net of approximately $380 million in deferred
income tax benefits arising from the transaction. The carrying amount of the
security is the $750 million principal amount less an approximate $105 million
remaining unamortized discount. The $815 million charge to paid-in capital will
reduce earnings available to common shareholders, in the same manner as TXU
Corp.'s existing preference share dividends.

transactions discussed above in Item 5 of this Form 8-K. In addition, TXU Corp.

earnings guidance for the first quarter of 2004, is attached to this Form 8-K as
