ITEM 5.       OTHER EVENTS AND REGULATION FD DISCLOSURE

         On May 18, 2004, TXU Corp. issued a press release announcing:

TXU, US Holdings, TXU Energy and Oncor
- --------------------------------------

         Capgemini Partnership
         ---------------------

         TXU has agreed to enter into a limited partnership with Capgemini to
form Capgemini Energy LP, a new company that will initially provide business
services and information technology solutions to TXU, with a plan to offer
similar services to other energy companies. Under the 10 year agreement,
approximately 2,700 employees will move [from subsidiaries of TXU] to Capgemini
Energy LP, effective July 1, 2004. Employees in Capgemini Energy LP will provide
information technology, call center, billing, human resources, supply chain and
accounts payable, and financial and accounting services to TXU and other energy
companies. TXU, through wholly-owned subsidiaries, will own less than 3% of
Capgemini Energy LP and has the right to sell all of its interest in the joint
venture to Capgemini upon termination of the contract.

         Initiatives to Improve Customer Service, Electric Delivery and
         --------------------------------------------------------------
         Production Reliability, and Operational Performance
         ---------------------------------------------------

         In addition to the formation of the Capgemini partnership described
above, TXU is undertaking a number of initiatives to improve customer service,
electric delivery and production reliability, and operational performance. These
initiatives include:

         o    investment for vegetation management across the electric
              distribution network, estimated at $45 million over the next three
              years, an increase of 70% over the last three years;

         o    investment in key transmission projects to further improve
              reliability and reduce congestion, estimated on average to be $80
              million annually over the next three years, a 35% increase over
              the 2003 investment level;

         o    investment of an additional $275 million over the next three years
              to improve reliability of coal and nuclear production assets, a
              45% increase in annual spending over the 2003 investment level;
              and

         o    replacement of four steam generators in one of the two units of
              the Comanche Peak nuclear plant in order to maintain the operating
              efficiency of the unit. Estimated capital requirements for this
              project, including purchase and installation, are $175 million to
              $225 million.



         Organizational Realignment
         --------------------------

         Beginning with the second quarter of 2004, TXU will be operated and
report its financial results along three core business segments consisting of:

         o  TXU Electric Delivery -- the regulated electric delivery business
            (the Oncor business)

         o  TXU Power -- the electric power production business

         o  TXU Energy -- the retail energy business

         Election of Officers
         --------------------

         TXU also named its executive management team. Tom Baker, previously
president of TXU Energy, will assume the position of chairman and chief
executive of TXU Electric Delivery. Mike Greene, previously president of Oncor,
will assume the position of chairman and chief executive of TXU Power. Paul
O'Malley will assume the position of chairman and chief executive of TXU Energy.

         In addition to the leadership of TXU's three core businesses, the
following TXU officers were named (and subsequently confirmed by the TXU Board
of Directors on May 21, 2004): Kirk Oliver, treasurer of TXU, was elected to the
additional position of executive vice president and chief financial officer;
Eric Peterson will continue as executive vice president and general counsel;
David Campbell, formerly of McKinsey & Company, Inc., was elected executive vice
president of corporate planning, strategy and risk.

         Liability Management
         --------------------

         TXU continues to pursue a comprehensive liability management program
geared toward increasing value and reducing risks. The liability management
program involves several actions, including the recent purchase of approximately
$423 million stated amount of equity-linked securities, thereby reducing debt,
eliminating the future issuance of 9.3 million common shares, and settling the
lawsuit filed October 9, 2003, in the Superior Court of the State of New York
relating to the equity-linked securities. TXU intends to repurchase over $4
billion of debt, equity or equity-linked securities in 2004, and an additional
$800 million to $900 million of debt, equity and equity-linked securities in
2005.

TXU, US Holdings and TXU Energy
- -------------------------------

         Investment in Trading Entity
         ----------------------------

         TXU Energy and Credit Swiss First Boston (USA), Inc. have entered into
a memorandum of understanding to work together on a 50/50 investment in an
entity that would become the exclusive energy marketing and trading vehicle for
both parties in North America. The new entity will market and trade power,
natural gas and other energy-related commodities in North America. The new
entity is expected to begin operation in the Fall of 2004.

         Strategic Review of Nuclear Assets
         ----------------------------------

         TXU announced its intent to undertake a strategic review of its nuclear
assets, comprised of two electricity generating units at Comanche Peak, each
with a capacity of 1,150 megawatts. The objectives of this strategic review are
to evaluate potential means to improve the long-term availability and certainty
of electrical supply for TXU Energy's customers.



TXU
- ---
         Capital Allocation
         ------------------

         TXU intends to utilize free cash flow in accordance with the following
priorities:

         o    First, investments to preserve and enhance the quality of customer
              service and production and delivery reliability;

         o    Second, reinvestments in its businesses, applying stringent
              expectations for cash payback  timelines and minimum return on
              investment; and

         o    Third, to reduce debt and other liabilities, with the objective of
              strengthening the balance sheet and increasing financial
              flexibility.

         Upon reaching the targeted balance sheet strength and financial
flexibility, management would recommend that the Board of Directors reevaluate
the current common stock dividend policy. At that time, management expects it
would recommend targeting annual common stock dividends equal to a payout of
100% of the earnings of Oncor. Of the free cash flow, management would expect to
return approximately 80% to shareholders in the form of distributions or
repurchases and retain approximately 20% for long-term growth initiatives.

         Assuming the execution of the business initiatives and transactions
described above, and depending on market trends in commodity prices, management
expects that the capital allocation program will enable management to recommend
an increase of the TXU common stock dividend in 2006. In addition to
management's recommendation, the Board of Directors may consider other relevant
factors in determining if and when to make a change in dividend policy.
