ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On November 22, 2004, TXU Corp. (the "Company") entered into an accelerated
share repurchase agreement with Citigroup Global Markets Inc. ("Citigroup") for
the repurchase of 52.5 million shares of its outstanding common stock at an
initial price of $64.57 per share. The Company expects to fund this transaction
with the proceeds from the anticipated closing of an offering of its debt
securities. Citigroup and certain of its affiliates have engaged, and may in the
future engage, in transactions with and perform services for the Company and
certain of its affiliates in the ordinary course of business, including as
lenders under certain of their credit facilities.

The accelerated share repurchase agreement is expected to close on November 26,
2004. The Company has the right to defer the closing of this transaction by five
business days if it has not closed the offering of its debt securities by that
date, and has the right to terminate the accelerated share repurchase agreement
if it has not closed the offering of its debt securities by the end of the five
business day deferral. Under the terms of the accelerated share repurchase
agreement, the Company will repurchase the 52.5 million shares immediately from
Citigroup. Citigroup will then purchase an equivalent amount of shares in the
open-market. Such purchases by Citigroup could take up to ten months or a
shorter period of time depending upon the amount of shares of common stock
purchased by Citigroup on a daily basis. The Company may receive from, or be
required to pay, Citigroup a price adjustment based upon the actual cost of the
shares purchased by Citigroup once such purchases are completed. Such price
adjustment can be settled, at the Company's option, in cash or in shares of its
common stock.

In the event of a default by the Company under the accelerated share repurchase
agreement, including a cross-default relating to certain other Company
indebtedness in a principal amount in excess of $50 million, Citigroup may
terminate or accelerate the transaction. In addition, Citigroup may elect to
terminate or accelerate this transaction in the event, and pro rata to the
extent, that it is no longer able to borrow (or maintain a borrowing of) shares
of the Company's common stock in an amount equal to the number of shares of the
Company's common stock which it has not yet purchased in the open market
pursuant to the accelerated share repurchase agreement. In the event of any such
termination or acceleration, the Company may be required to compensate Citigroup
for any loss it incurs in connection therewith.
