    DALLAS, Oct. 10 /PRNewswire-FirstCall/ -- TXU Corp. (NYSE:   TXU) today
 announced the completion of its merger agreement with Texas Energy Future
 Holdings Limited Partnership (TEF). TEF is led by a group of investors
 including Kohlberg Kravis Roberts & Co. (KKR), Texas Pacific Group (TPG)
 and Goldman Sachs Capital Partners. TXU shareholders overwhelmingly
 approved the merger at the company's Annual Meeting on September 7, 2007.
     With the completion of the merger, TXU Corp. has changed its name to
 Energy Future Holdings Corp. Shares of TXU common stock, which are listed
 on the New York Stock Exchange and the Chicago Stock Exchange, ceased
 trading at close of market today and will be delisted. Under the terms of
 the merger agreement, TXU shareholders are entitled to $69.25 in cash for
 each share of TXU common stock held. Lehman Brothers, Citigroup and Morgan
 Stanley became equity investors at closing.
     Completion of the merger agreement marks the final step in the
 transformation into a privately held company that is already delivering
 price cuts, price protection and low-income customer benefits, as well as
 taking actions to provide affordable power for years to come. In addition,
 the company will seek to achieve top environmental performance in the
 industry and greater involvement and dialogue with environmental,
 government and community leaders.
     "Our investment horizon allows the board, management and employees to
 formulate and implement a long-term strategy to meet customer needs and to
 respond to the significant energy challenges in Texas," said Marc
 Lipschultz of KKR.
     Since the announcement of the merger transaction on February 26, 2007,
 TEF's plans for the company's new direction have received support from
 consumer groups, environmental groups, labor unions, business leaders and
 elected officials from communities across Texas.
     "We have maintained open and productive dialogues with legislators,
 regulators, customers and consumer advocates. Together, we are proud to be
 part of a transformation that will benefit -- and in fact already is
 benefiting -- customers and residents of the state of Texas," said Michael
 MacDougall of TPG.
     New Leadership
     With the close of the transaction, Donald L. Evans becomes
 non-executive chairman of Energy Future Holdings Corp. Evans previously
 served as U.S. Secretary of Commerce for four years under President George
 W. Bush.
     "We are excited about the opportunities that the completion of this
 merger provides. This transaction is not only good for TXU shareholders,
 but also for employees, customers and residents across the state of Texas,"
 said Evans. "I look forward to working with management and employees to
 demonstrate our commitment to being a leading corporate citizen, to
 implementing stronger environmental policies and to providing reliable and
 affordable power."
     As non-executive chairman, Evans will lead the company's board of
 directors, which as previously announced will include: William Reilly,
 Chairman Emeritus of the World Wildlife Fund and former EPA Administrator;
 Lyndon Olson, former U.S. Ambassador to Sweden; James Huffines, Chairman of
 the Central Region Plains Capital Bank; and Kneeland Youngblood of Pharos
 Capital Group, LLC. Former U.S. Secretary of State James A. Baker, III will
 serve as advisor to the company.
     "This company and its employees are ready for the next step. We look
 forward to implementing additional separation of our three businesses so
 each can focus on the distinct customers they serve," said Tom Baker,
 Vice-Chairman of TXU Corp. who will transition to Chairman Emeritus of
 Energy Future Holdings Corp.
     As previously announced, with the successful completion of the
 transaction, C. John Wilder has resigned as TXU Corp. Chairman and CEO.
 Since his arrival in February 2004, Wilder led the company to substantial
 performance improvements including: outstanding shareholder returns; a
 successful business turnaround; and a major restructuring of the operations
 and growth program.
     "I am proud of what TXU has become and confident that the company is in
 good hands. Because of the hard work of TXU employees, these businesses are
 operating at safe, high-performance levels across many dimensions," said
     Evans concluded, "I'd like to thank John Wilder and the outgoing board
 of directors for their years of service to the company. They leave a
 company of outstanding men and women, dedicated to excellence in customer
 service and energy reliability. We wish them well in their future
     Three Separate and Distinct Companies
     Energy Future Holdings Corp., a holding company, will continue the
 transition of its businesses into three separate and distinct business
 units with separate boards, management teams, and headquarters.
     Each business will operate independently under the leadership of a CEO:
      -- Jim Burke will serve as CEO of TXU Energy, a competitive electricity
      -- Mike Greene will serve as CEO of Luminant, a competitive power
         generation business, including mining, wholesale marketing and
         trading, and construction; and
      -- Bob Shapard will serve as CEO of Oncor, a regulated electric
         distribution and transmission business.
     To maintain smooth ongoing operations, current business unit management
 and organizational structures will remain in place at least through a
 transition period, which is expected to be complete in the first half of
 2008. Beyond the further separation of the three primary businesses, most
 employees will experience few differences in their day-to-day jobs. The
 transition will be seamless to customers.
     Headquarters for each of the three businesses will remain in the
 Dallas/Fort Worth area.
     Price Cuts
     As a result of the close of the transaction, TXU Energy will reduce
 retail prices by an additional 5%, resulting in a total 15% price reduction
 in 2007 for residential customers who had not already chosen one of TXU
 Energy's lower-priced or environmentally friendly options. With this
 additional reduction TXU Energy will continue to offer the lowest prices of
 any incumbent competitive retailer in Texas. The value of TXU Energy's
 lower prices, innovative range of products to meet customer needs, and
 focus on customer service have contributed to an increase in customer count
 over the past few months.
     $150 Million Commitment to Low-Income Assistance
     TEF and TXU Energy have announced the creation of TXU Energy Access, a
 comprehensive program representing a commitment of more than $150 million
 over 5 years to assist low-income customers.
     Environmental Benefits
     As part of the transaction, TEF made a range of commitments to
 strengthen environmental policies, make significant investments in
 alternative energy and institute corporate policies tied to climate
 stewardship. Those efforts helped earn the endorsement of Environmental
 Defense and the Natural Resources Defense Council, two of the nation's
 largest and most respected environmental organizations.
     In keeping with the commitment to reduce the number of planned
 coal-fueled generation units from 11 to three, the eight air permit
 applications will be withdrawn by Luminant. The eight air permit
 applications were suspended shortly following the announcement of the
 merger agreement.
     In addition, Energy Future Holdings Corp. will create a Sustainable
 Energy Advisory Board comprised of individuals who represent the following
 interests: the environment; customers; Texas economic development; and
 ERCOT reliability standards. Board member William Reilly, Chairman Emeritus
 of the World Wildlife Fund and former Administrator of the U.S.
 Environmental Protection Agency, will lead the effort to make climate
 stewardship central to corporate policies.
     In advance of the close of the transaction, Oncor and TEF reached an
 agreement in principle with the key parties that would resolve all
 outstanding issues in the Public Utility Commission of Texas (PUC) review
 under Public Utility Regulatory Act Section 14.101 related to the change in
 control of Oncor. The agreement includes provisions under which the PUC
 would dismiss Oncor's pending rate case. The agreement is subject to
 approval by the PUC.
     Following the close of the acquisition of TXU Corp. and as previously
 disclosed, TEF will sell a twenty percent stake in Oncor. Now that the
 acquisition is complete, the minority stake sale process will commence
 shortly and is an important element of the investor group's plan. The sale
 of a twenty percent minority stake in Oncor has long been part of TEF's
 plan to enhance Oncor's independence and separation from TXU Corp., TXU
 Energy and Luminant. The purchaser of the twenty percent stake will not be
 affiliated with any of the companies owned by TXU Corp. or the parties
 involved in this transaction, and will have meaningful representation on
 the Oncor board of directors.
     In addition, Oncor plans to secure all of its currently existing
 long-term debt. This does not include the $800 million principal amount of
 floating rate senior notes that were redeemed upon completion of the merger
 as required by the terms of the notes. Oncor's $2 billion credit facility
 is also secured.
