                TXU DEFERRED COMPENSATION PLAN FOR DIRECTORS OF SUBSIDIARIES

                          NOTES TO FINANCIAL STATEMENTS

1.      Plan Description -- The TXU Deferred Compensation Plan for Directors of
        Subsidiaries (Plan) is sponsored by TXU Corp. (Company) and is
        administered by the Organization and Compensation Committee of the
        Company's Board of Directors. Members of the boards of directors and/or
        advisory boards of directors of participating subsidiaries of the
        Company who are not current or former officers or employees of the
        Company or any of its subsidiaries (Outside Directors) are eligible to
        participate in the Plan. The Plan allows Outside Directors to defer a
        percentage of their annual retainer exclusive of any attendance fee or
        other compensation in 25% increments up to 100%.

        A participant's benefits under the Plan are provided through an
        irrevocable grantor trust established by the Company as agent for the
        participating subsidiaries. The trust assets contributed by a
        participating subsidiary are subject to the claims of the general
        creditors of the participating subsidiary. At the beginning of the Plan
        year, each participating subsidiary provides the trust with funds equal
        to the annual deferrals of the participating subsidiary's participants.
        The trustee invests such funds in shares of common stock of the Company
        (Common Stock). The trustee uses any cash dividends received on Common
        Stock held in the trust to buy additional shares of Common Stock.

        A participant's deferrals are credited to the participant's account
        under the Plan and are converted into performance units on the basis of
        the number of shares of Common Stock that can be purchased with the
        deferral amounts as of the applicable date. Additional performance units
        are credited to a participant's account, determined by multiplying the
        number of performance units in the participant's account by the amount
        of any regular or special cash dividend declared on each share of Common
        Stock and dividing the product by the amount paid by the trust for a
        share of Common Stock with the dividend amounts received by the trust.

        On the expiration of the applicable maturity period elected by a
        participant (not fewer than 3 years and not more than 10 years), the
        value of the participant's account at maturity is paid in whole shares
        of Common Stock or in cash at the participant's election. In the event a
        participant's service is terminated because of death or disability,
        amounts in the participant's account shall mature upon such termination.
        In the event a participant's service terminates for reasons other than
        death or disability, amounts in the participant's account shall mature
        at the end of the applicable maturity period. If the participant's
        service terminates prior to the end of a Plan year, the deferred amount
        and the dividend equivalent credits earned will be recomputed as of the
        termination date. The deferred amount and dividend equivalent credits
        that are unearned will be forfeited and revert back to the Company.

        In the event of a change in control of the Company, forfeiture
        provisions are eliminated; amounts maturing within 12 months are to be
        paid within 30 days of the change in control; and amounts maturing more
        than 12 months from the change in control may, at the election of the
        Outside Director, be paid on the first anniversary of the change in
        control or when they would otherwise mature.

        The number of participants at March 31, 2003 and 2002 was 21 and 22,
        respectively.

2. Summary of Significant Accounting Policies:

        Basis of Accounting -- The financial statements of the Plan are prepared
        under the accrual method of accounting.

        Use of Estimates -- The preparation of financial statements in
        conformity with accounting principles generally accepted in the United
        States of America requires management to make estimates and assumptions
        that affect the reported amounts of Plan assets and changes therein.
        Actual results could differ from those estimates.

                                        3




        Expenses -- All costs and expenses of the Plan and its administration
        except expenses incurred in the acquisition or disposition of
        investments are paid by the Company.

3.   Plan Investments -- The historical cost, fair value and unrealized
     appreciation (depreciation) of investments at March 31, and for the years
     then ended, are as follows:




                                          Number of   Historical   Market    Appreciation/
      Common stock of TXU Corp             Shares        Cost      Value    (Depreciation)
      ------------------------             ------        ----      -----    --------------
                                                                  
          2003                              16,167 (a) $657,771    $288,581   $(369,190)
          2002                              13,390 (b) $513,346    $729,887    $216,541
          2001                               9,946 (c) $365,619    $410,987    $ 45,368



- ------------------------------
(a) Represents 0.0050% of the outstanding shares of common stock of TXU
    (322,155,194 at March 31, 2003).
(b) Represents 0.0050% of the outstanding shares of common stock of TXU
    (266,124,117 at March 31, 2002).
(c) Represents 0.0039% of the outstanding shares of common stock of TXU
    (258,138,897 at March 31, 2001).

       The investment in Common Stock is stated at fair value based upon the
       last reported sale price on recognized exchanges on the last business
       day of the Plan year. Changes in the fair value are reflected as
       unrealized appreciation (depreciation). The cost basis of Plan
       investments was changed from average cost to first-in first-out during
       the 2003 Plan year. The effect of the change was not material.

       During the 2003, 2002 and 2001 Plan years, realized gains and losses
       (reflected in the change in appreciation (depreciation) of investments)
       were immaterial. Distributions for maturing accounts are paid from new
       contributions to the extent available, and the ownership of performance
       units is effectively transferred from the maturing account to the new
       participant's account. This minimizes realized gain or loss because the
       Plan's investments are generally not sold and repurchased.

       The Plan's investment in Common Stock is subject to various risks, such
       as interest rate, credit and overall market volatility. Therefore, it is
       reasonably possible that changes in the value of Common Stock will occur
       in the near term and that such changes could materially affect the
       amounts reported in the statement of financial condition.

4.     Plan Contributions -- Contributions by participating Outside Directors
       for the Plan years ended March 31, 2003, 2002 and 2001 were $128,000,
       $132,000 and $116,000, respectively.

5.     Distributions Payable -- In accordance with Plan requirements, accounts
       maturing at March 31, 2003 resulted in distributions totaling $44,605
       paid in April 2003.

6.     Federal Income Taxes -- The Plan does not, and is not intended to, meet
       the requirements of a tax-qualified plan under Section 401(a) of the
       Internal Revenue Code (Code). Therefore, the trust which the Company has
       established under the Plan in order to provide Plan benefits is not
       exempt from federal income taxes under Section 501 (a) of the Code.

       Based on the Code and the regulations thereunder as currently in effect:

      (a)   A participant's elective deferrals under the Plan, and any
            dividends, interest or other income thereon will not be subject to
            federal income tax until the year such amounts are paid or otherwise
            made available to the participant.

      (b)   Elective deferrals under the Plan are not deductible by the
            participant on his or her federal income tax return, since elective
            deferrals are not includable in the participant's income.

                                        4


      (c)   Amounts distributed under the Plan will be taxable as ordinary
            income to the participant in the year of such distribution.

7.     Amendment or Termination -- The Company's Board of Directors may amend,
       terminate, or suspend the Plan at any time. An amendment or modification
       of the Plan may affect active participants as well as future
       participants, but no amendment or modification of the Plan for any reason
       may diminish any participant's account as of the effective date thereof.
       Upon termination of the Plan, the deferred amount and dividend equivalent
       credits will be recomputed as of the date of termination.




                                        5




INDEPENDENT AUDITORS' REPORT


Organization and Compensation Committee,
   TXU Deferred Compensation Plan
   for Directors of Subsidiaries:

We have audited the accompanying statements of financial condition of the TXU
Deferred Compensation Plan for Directors of Subsidiaries (The "Plan") as of
March 31, 2003 and 2002, and the related statements of operations and changes in
plan equity for the years ended March 31, 2003, 2002 and 2001. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial condition of the Plan at March 31, 2003 and
2002, and the related operations and changes in plan equity for each of the
three years in the period ended March 31, 2003, in conformity with accounting
principles generally accepted in the United States of America.
