Dear Fellow Shareholder:

We encourage you to vote now FOR the proposed TXU merger. The September 7, 2007 TXU Corp. Annual Meeting is fast approaching. At the Annual Meeting, shareholders will consider the approval of a merger agreement pursuant to which an investor group led by Kohlberg Kravis Roberts & Co., Texas Pacific Group and Goldman Sachs & Co. would acquire TXU for $69.25 per share in cash. We wanted to make sure you have the facts about the proposed transaction. Your Board of Directors has unanimously recommended that shareholders vote in favor of the proposed merger agreement.

Please consider these factors in deciding how you will vote:

• The Board determined that the $69.25 per share offer maximizes value to shareholders and is superior to any alternative the Board considered.

• The offer represented a 25% premium to the average closing price during the 20 trading-day period prior to press speculation about a possible merger transaction.

• An independent and objective process was used to evaluate the offer.

• In light of volatile commodity and equity market signals, your Board of Directors re-evaluated its recommendation in July and re-affirmed the recommendation of a vote “FOR” the merger.

• Recently, each of the four most prominent proxy advisory firms affirmed the Board’s unanimous recommendation that shareholders vote ‘FOR’ the proposed merger agreement. Many institutional shareholders rely on these independent firms in determining how they will vote.

Since approval of the merger requires the affirmative vote of at least two-thirds of the outstanding shares of common stock, your vote is important, no matter how many or how few shares you own. Not voting has the same effect as voting against the merger.

If you have not already done so, please vote your shares by marking, signing and dating the enclosed proxy card and returning it in the envelope provided. You may also vote your shares by telephone or through the Internet by following the instructions provided on the enclosed proxy card.

We urge you to vote FOR the merger today. If shareholders approve the merger and it closes as expected, you will receive $69.25 per TXU share.

Very truly yours,

C. John Wilder
Chairman, President and CEO
