benefits described below:
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | Cash Severance Payment. The Company will pay Executive a one-time, lump-sum cash severance payment equal to two times the sum of Executives base salary and target
annual bonus under the Companys Executive Annual Incentive Plan (EAIP). The payment, net of all taxes and required withholdings, shall be paid to Executive on the Separation Date, or as soon thereafter as administratively
possible, but in no event later than the third (3rd) business day after the Separation Date.

| | (ii) | Pro-Rata Annual Bonus for 2007. The Company will pay Executive a one-time bonus consistent with the bonuses paid under the EAIP. The bonus shall be based on actual
performance for 2007 as determined by the TXU Corp. Board of Directors Organization and Compensation Committee (O&C Committee) prior to Closing up to the maximum level of performance and pro-rated for the portion of the

compensation awards (LTIP Awards) granted in 2005, 2006 and 2007 pursuant to Executives Employment Agreement. The performance units shall be valued based upon the product of: (x) the number of shares payable pursuant to
each performance award (adjusted to reflect the Companys attainment or non-attainment of the performance criteria set forth in the Employment Agreement as determined by the Companys O&C Committee prior to the effective time of the
Closing); and (y) the price of TXU Corp.s stock paid in connection with the merger at Closing (Per Share Merger Consideration), provided, however, that that with respect to awards granted in 2007, the performance
adjustment has been capped at one hundred percent (100%). The cash payment representing the LTIP Award payment described in this Sub-Section 2.1(a)(iii) will be deposited in a rabbi trust held by Wells Fargo Bank (Wells Fargo Rabbi
Trust) and the cash invested as directed by the Company. The cash (plus any accumulated earnings) will be distributed to Executive on the later of the Separation Date or January 2, 2008.

location, together with secretarial assistance, phone and internet service, for a period of one (1) year beginning on the Separation Date. Executive shall be provided two lump-sum payments in connection with the office related expenses provided
under this Agreement. The first payment will cover such expenses for the period from the Separation Date through December 31, 2007 and shall be made net of all taxes and other withholdings on the Separation Date or as soon thereafter as
administratively possible, but in no event later than the third (3rd) business day after the Separation Date. The second payment will be
deposited into the Wells Fargo Rabbi Trust on or before the Separation Date, will cover such expenses for the period from January 1, 2008 through the end of the one year period and shall be distributed by the Trust to the Executive on
January 2, 2008. Such secretarial assistance shall be provided at Companys expense for such one (1) year period by Executives current administrative assistant, Janice Wallace, who shall remain subject to the Companys
policies and procedures for as long as she is employed by the Company. Following such one (1) year period and consistent with prior practice for the departing Chairman and Chief Executive Officer, Executive can elect to reimburse the Company at
costs for services of Ms. Wallace during her employment with the Company.

---

| | (v) | Accrued Obligations. A one-time, lump sum cash payment for: a) Executives base salary through the Separation Date, to the extent it has not already been paid; b)
Executives unused vacation days as of the Separation Date, to the extent it remains unused and he has not otherwise been paid for it; and c) any expense reimbursements to which Executive is entitled through the Separation Date, to the extent
it has not already been paid. The payment shall be paid to Executive on the Separation Date, or as soon thereafter as administratively possible, but in no event later than the third (3rd) business day after the Separation Date.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | COBRA. To the extent Executive elects to continue medical benefits pursuant to the Consolidated Omnibus Budget
Reconciliation Act of 1985 (COBRA), the Company will offer Executive and his eligible dependents COBRA coverage for eighteen (18) months, subject to COBRAs provisions. The Company will provide Executive on the
Separation Date, or as soon thereafter as administratively possible, but in no event later than the third (3rd) business day after the
Separation Date, a one-time, lump-sum payment, net of all taxes and other withholdings, of the difference between the total cost of COBRA coverage and the employee rate that Executive will be required to contribute.
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vii) | Gross-up. Pursuant to Section 4.6 of the Employment Agreement, if any payment, distribution or provision of a benefit provided or to be provided under the terms of this
Agreement (Payment) is or would be subject to an Excise Tax (as defined in the Employment Agreement), Executive shall be paid the Gross-up Payment (as defined in the Employment Agreement).
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company, along with its outside tax advisors, will develop an estimate of the Gross-up Payment and provide it to Executive prior to the Separation
Date; and that estimate will determine the Gross-up Payment. The Parties agree that all Gross-up Payments will be determined, paid and otherwise treated consistent with Exhibit 2 to this Agreement.

The Company shall deposit into the Wells Fargo Rabbi Trust, on or before the Separation Date, funds to cover Executives excise taxes and Gross-up
Payments related to payments made pursuant to Sections 2.1(a)(iii), 2.1(a)(iv) and 2.2(c). The Company or, in the case of payments under Sections 2.1(a)(iii), 2.1(a)(iv) and 2.2(c), the Wells Fargo Rabbi Trust and/or any other trust established for
the purpose of funding Gross-up Payments, shall: (1) pay all of the excise taxes that the Company and Executive believe are owed with respect to the Payment no later than on the business day following the date of payment; (2) impute such taxes
paid into the income of the Executive; and (3) pay all taxes related to such income imputation no later than on the business day following the date of payment. As a result of the foregoing tax payments by the Company, the Payment made to
the Executive will not be reduced by any such excise taxes or additional taxes on the imputed income. The Company shall



4



---

report such additional income and the total amount of taxes paid on the Executives Form W-2 for the year of payment. Any other Gross-up Payment to
which Executive is entitled will be paid at the time when the relevant tax is due. All these payments will be reduced by normal required income and employment tax withholding and will be reported as income on the Executives Form W-2 for the
year in which payment occurs. For the avoidance of doubt, this last paragraph of Section 2.1(a)(vii) of this Agreement shall not operate to reduce or eliminate any Gross-up Payment to which Executive is entitled under Section 4.6 of
the Employment Agreement, but merely clarifies the timing of such payments.



| | b. | The Company and Executive agree that the payments and benefits described in Section 2.1(a) above shall be in lieu of any other separation, severance incentive or benefits
offered under any plan, program or agreement (including the Employment Agreement) to which Executive may have been, or to which Executive believes he may be, entitled as a result of his employment with or separation from the Company or any
Affiliate, except for those distributions specifically provided for in Section 2.2 below. Any such payments shall be less any applicable tax and/or withholdings, deductions or obligations, including any amounts owed to the Company or an
Affiliate by Executive on any Company issued or sponsored travel or credit cards or any other expenses or payments for which the Company is entitled to be reimbursed by Executive.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.2 | Benefits
|--- | --------



| | a. | It is agreed that, from and after the Separation Date, Executive shall not be eligible to continue to participate in any employee benefit plan, program or policy sponsored by the

pursuant to the Special Incentive Compensation Award (as defined in the Employment Agreement) made to Executive following his execution of the Employment Agreement. As provided for in the Employment Agreement, the receipt of such shares was deferred
pursuant to the terms of a letter dated June 20, 2005 from Executive to the Company. The parties agree that, upon Closing, such deferred shares will be converted into cash in an amount equal to the Per Share Merger Consideration times the
number of shares held in the Mellon Bank Rabbi Trust. The cash will be invested consistent with the terms of the Mellon Bank Rabbi Trust, and the cash (plus any accumulated earnings), less applicable federal, state and local tax withholding, will be
distributed to Executive on the later of the Separation Date or January 2, 2008.
