MIRANT CORPORATION

CHANGE IN CONTROL SEVERANCE PLAN

ARTICLE 1

PURPOSE AND TERM

1.1 Purpose. The Board of Directors of the Company has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication of certain key employees, notwithstanding the possibility, threat or occurrence of a Change in Control of the Company. The Board believes it is imperative to diminish the inevitable distraction of such key employees by virtue of the personal uncertainties and risks created by a threatened or pending Change in Control, and to encourage the key employees’ full attention and dedication to the Company currently and in the event of any threatened or pending Change in Control, and to provide the key employees with compensation and benefits arrangements upon a Change in Control. Therefore, in order to accomplish these objectives, the Board has caused the Company to adopt this Plan.

The Plan is intended to qualify under Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA as an unfunded plan maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees.

1.2 Term. The Plan shall generally be effective as of the Effective Date, subject to amendment from time to time in accordance with Section 7.2. The Plan shall continue until terminated pursuant to Article 7 of the Plan.

ELIGIBILITY

3.1 Participation. The Committee or the Board shall designate from time to time those Employees or classes of Employees who are Participants in the Plan. In the

- 4 -

event the Committee or the Board designates certain Participants by job title, position, function or responsibilities, an Employee who is appointed to such a position after the Effective Date of this Plan shall be a Participant upon the date he or she begins his or her duties in such position, unless otherwise determined by the Committee or the Board. The Committee or the Board shall designate each Participant in the Plan as a Tier I, Tier II or Tier III Employee. Exhibit A, attached hereto and made a part hereof, sets forth the initial Participants and their respective Tier Levels, which may be amended by the Committee or the Board at any time prior to a Change in Control to add or remove individual Participants or classes of Participants or to change Tier Level classifications; provided, however, that the removal of individual Participants or classes of Participants from the Plan, or any change in Tier Level classification to a lower Tier Level with respect to any individual Participant or class of Participants shall not be effective for at least 12 months after the date of the Committee or Board action. If a Change in Control occurs during such 12-month period, any such action to remove individual Participants or classes of Participants or to place individual Participants or classes of Participants in a lower Tier Level shall be null and void.

3.2 Duration of Participation. Subject to Article 4 and Article 7, an Employee shall cease to be a Participant in the Plan if (i) his or her employment is terminated under circumstances in which he or she is not entitled to Severance Benefits under the terms of this Plan, or (ii) prior to a Change in Control, he or she ceases to be among the class of employees designated by the Committee or the Board as Participants. Notwithstanding the foregoing, a Participant who has terminated employment and is entitled to Severance Benefits under Section 4.1 shall remain a Participant in the Plan until the full amount of the Severance Benefits and any other amounts payable under the Plan have been paid to the Participant.

ARTICLE 4

SEVERANCE BENEFITS

4.1 Right to Severance Benefits.

(a) A Participant shall be entitled to receive from the Company Severance Benefits in the amount provided in Section 4.2 if, within the two-year period following a Change in Control, (i) the Participant’s employment with the Company or any Affiliate is terminated by the Company without Cause (other than by reason of the Participant’s death or Disability) or (ii) the Participant’s employment is terminated by the Participant for Good Reason within a period of 90 days after the occurrence of the event giving rise to Good Reason.

(b) If a Change in Control occurs and (i) a Participant’s employment with the Company or any Affiliate was terminated by the Company without Cause (other than by reason of the Participant’s death or Disability) prior to the date of the Change in Control or (ii) an action was taken with respect to the Participant prior to the date of the Change in Control that would have constituted Good

- 5 -

Reason if taken after a Change in Control, and the Participant can reasonably demonstrate that such termination or action, as applicable, occurred at the request of a third party who had taken steps reasonably calculated to effect the Change in Control, then the termination or action, as applicable, will be treated for all purposes of this Plan as having occurred immediately following the Change in Control and such former Participant shall be entitled to the benefits of the Plan accordingly.

(c) Notwithstanding anything to the contrary, no Severance Benefits shall be provided to a Participant unless the Participant has executed and not revoked a release in substantially the form attached hereto as Exhibit B (the “Release”).

4.2 Amount of Severance Benefits. If a Participant’s employment is terminated in circumstances entitling him or her to Severance Benefits as provided in Section 4.1, then:

(a) the Company shall pay to the Participant in a single lump sum cash payment within 30 days after the Termination Date or such later date as may be required by Section 4.5 of the Plan, the aggregate of the following amounts:

(i) the sum of (x) the Participant’s Base Salary through the Termination Date to the extent not theretofore paid, (y) the product of (A) the Participant’s Target Annual Bonus for the year in which the Termination Date occurs, and (B) a fraction, the numerator of which is the number of days in the current fiscal year through the Termination Date, and the denominator of which is 365, and (z) any accrued vacation pay to the extent not theretofore paid; and

(ii) a severance payment equal to three times, in the case of a Tier I Employee, or two times, in the case of a Tier II Employee, or one times, in the case of a Tier III Employee, the sum of (x) the Participant’s Base Salary and (y) the Target Annual Bonus for the year in which the Termination Date occurs; and

(iii) a payment equal to the cost to the Company to provide certain group health benefits sponsored by Company and maintained by the Participant on the Termination Date. The amount payable under this Section 4.2(a)(iii) shall be calculated based on the monthly cost to the Company (exclusive of any portion of the cost paid by the employee) to provide the same level of coverage of such group health benefits maintained by the Participant as of the Termination Date for 36 months, in the case of a Tier I Employee, or 24 months, in the case of a Tier II Employee, or 12 months, in the case of a Tier III Employee. For purposes of this Section 4.2(a)(iii), group health benefits means any of the

- 6 -

following: group medical, dental, vision, and/or prescription drug benefits. The cost of such group health coverage is based on the monthly premium charged to the Company for such coverage on the Termination Date by an insurance carrier if such benefit is provided pursuant to an insurance contract issued by an insurance carrier to the Company. If the coverage is self-insured by the Company, the cost will be the monthly cost as determined by the Company in accordance with reasonably acceptable means (for self-insured group health, the cost shall equal the “applicable premium” under COBRA for such benefits for the year in which the Termination Date occurs). The Participant will be entitled to make an election to continue group health benefits in accordance with the terms of the various group health plans.

(b) all of the Participants stock options and other equity awards in the nature of rights that may be exercised shall become fully vested and exercisable and the post-termination exercise period shall be governed by the agreements evidencing such awards, and all restrictions on any other outstanding equity awards shall lapse; and

(c) to the extent not theretofore paid or provided, the Company shall timely pay or provide to the Participant any other amounts or benefits required to be paid or provided or which the Participant is eligible to receive under any plan, program, policy or practice or contract or agreement of the Company and its affiliated companies.

4.3 Non-Duplication of Benefits. This Plan is not intended to supersede any other plan, program, arrangement or agreement providing a Participant with severance or related benefits in the case of termination of employment following a Change in Control. In the event that a Participant becomes entitled to receive benefits under this Plan and any such benefit duplicates a benefit that would otherwise be provided under any other plan, program, arrangement or agreement as a result of the Participant’s termination of employment, then the Participant shall be entitled to receive the greater of the benefit available under the Plan, on the one hand, and the benefit available under such other plan, program, arrangement or agreement, on the other.

4.4 Full Settlement; No Mitigation. The Company’s obligation to make the payments provided for under this Plan and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Participant or others. In no event shall the Participant be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Participant under any of the provisions of this Agreement and such amounts shall not be reduced whether or not the Participant obtains other employment.

4.5 Code Section 409A. Notwithstanding the foregoing provisions of this

- 7 -

Article 4, to the extent required to comply with Section 409A of the Code, amounts and benefits to be paid under this Article 4 shall be delayed to the six month anniversary of the date of the Participant’s separation from service, within the meaning of Code Section 409A.

ARTICLE 5

EFFECT OF SECTIONS 280G AND 4999 OF THE CODE

5.1 Certain Additional Payments by the Company. This Section 6.1 shall be applicable to all Tiers of Employee Participants.

(a) Anything in this Plan to the contrary notwithstanding and except as set forth below, in the event it shall be determined that any benefit, payment or distribution by the Company to or for the benefit of a Tier I and Tier II Employee Participant (whether paid or payable or distributed or distributable pursuant to the terms of this Plan or otherwise, but determined without regard to any additional payments required under this Section 5.1) (such benefits, payments or distributions are hereinafter collectively referred to as “Payments”) would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the Participant with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the Participant shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the Participant of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the Participant retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments with a maximum benefit of $2 million.

Notwithstanding the foregoing provisions of this Section 5.1(a), if the Parachute Value (as defined below) of all Payments does not exceed 110% of the Participant’s Safe Harbor Amount (as defined below), then the Company shall not pay the Participant a Gross-Up Payment, and the Payments due under this Plan shall be reduced so that the Parachute Value of all Payments, in the aggregate, equals the Safe Harbor Amount; provided, that if even after all Payments due under this Plan are reduced to zero, the Parachute Value of all Payments would still exceed the Safe Harbor Amount, then no reduction of any Payments shall be made and the Gross-Up Payment shall be made. The reduction of the Payments due hereunder, if applicable, shall be made in such a manner as to maximize the economic present value of all Payments actually made to the Participant, determined by an independent, nationally recognized accounting firm or compensation consulting firm (the “Determination Firm”) for purposes of Section 280G of the Code using the discount rate required by Section 280G(d)(4) of the Code. For purposes of this Section 5.1, the “Parachute Value” of a Payment

- 8 -

means the present value as of the date of the change of control for purposes of Section 280G of the Code of the portion of such Payment that constitutes a “parachute payment” under Section 280G(b)(2) of the Code, as determined by the Determination Firm for purposes of determining whether and to what extent the Excise Tax will apply to such Payment. For purposes of this Section 5.1, the Participant’s “Safe Harbor Amount” means one dollar less than three times the Participant’s “base amount” within the meaning of Section 280G(b)(3) of the Code.

(b) Subject to the provisions of Section 5.1(c), all determinations required to be made under this Section 5.1, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be used in arriving at such determination, shall be made the Determination Firm which shall provide detailed supporting calculations both to the Company and the Participant within 15 business days of the receipt of notice from the Participant that there has been a Payment, or such earlier time as is requested by the Company. All fees and expenses of the Determination Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 5.1, shall be paid by the Company to the Participant within five days of the receipt of the Determination Firm’s determination. Any determination by the Determination Firm shall be binding upon the Company and the Participant; provided that if, the Determination Firm’s initial determination to the contrary notwithstanding, the Internal Revenue Service (or other applicable taxing authority) determines that an additional Excise Tax is due with respect to the Payments, the Determination Firm shall recalculate the amount of the Gross-Up Payment based upon the determinations made by the Internal Revenue Service (or other applicable taxing authority) after taking into account any additional interest and penalties (the “Recalculated Amount”) and the Company shall pay to the Participant, within 5 days of the receipt of the Determination Firm’s recalculation the Gross-Up Payment, the excess of the Recalculated Amount over the Gross-Up Payment initially paid to the Participant. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Determination Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (“Underpayment”), consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to Section 5.1(c) and the Participant thereafter is required to make a payment of any Excise Tax, subject to the maximum, the Determination Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Participant, together with interest, from the time of payment by the Participant of such Excise Tax, at the applicable Federal rate provided for in Section 7872(f)(2) of the Code.

(c) The Participant shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by

- 9 -

the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten business days after the Participant is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Participant shall not pay such claim prior to the expiration of the 30-day period following the date on which it gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Participant in writing prior to the expiration of such period that it desires to contest such claim, the Participant shall:

(i) give the Company any information reasonably requested by the Company relating to such claim,

(ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, and designating such attorney as authorized to act on the Participant’s behalf with respect to such examination, if necessary, through a power of attorney,

(iii) cooperate with the Company in good faith in order effectively to contest such claim, and

(iv) permit the Company to participate in any proceedings relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Participant harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation of the foregoing provisions of this Section 5.1(c), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Participant to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Participant agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs the Participant to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Participant, on an interest-free basis and shall indemnify and hold the Participant harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any

- 10 -

imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Participant with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Participant shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(d) If, after the receipt by the Participant of an amount advanced by the Company pursuant to Section 5.1(c), the Participant becomes entitled to receive any refund with respect to such claim, the Participant shall (subject to the Company’s complying with the requirements of Section 5.1(c)) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Participant of an amount advanced by the Company pursuant to Section 5.1(c), a determination is made that the Participant shall not be entitled to any refund with respect to such claim and the Company does not notify the Participant in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

ARTICLE 6

TERMINATION OF EMPLOYMENT

6.1 Written Notice Required. Any purported termination of employment, whether by the Company or by the Participant, shall be communicated by written notice to the other (a “Notice of Termination”).

6.2 Termination Date. In the case of the Participant’s death, the Participant’s Termination Date shall be his or her date of death. In all other cases, the Participant’s Termination Date shall be the date specified in the Notice of Termination subject to the following:

(a) If the Participant’s employment is terminated by the Company for Cause or due to Disability, the date specified in the Notice of Termination shall be at least 30 days from the date the Notice of Termination is given to the Participant, provided that in the case of Disability, the Participant shall not have returned to the full-time performance of his or her duties during such period of at least 30 days; and

(b) If the Participant terminates his or her employment for Good Reason, the date specified in the Notice of Termination shall not be more than 60 days from the date the Notice of Termination is given to the Company.

- 11 -

ARTICLE 7

DURATION, AMENDMENT AND TERMINATION, CLAIMS

7.1 Duration. The Plan shall become effective as of the Effective Date. The Board may terminate the Plan as of any date that is at least 12 months after the date of the Board’s action. If a Change in Control occurs during such 12-month period, this Plan shall continue in full force and effect and shall not terminate or expire until after all Participants who become entitled to any payments hereunder shall have received such payments in full.

7.2 Amendment and Termination. Subject to the following sentence, the Plan may be amended from time to time in any respect by the Board; provided, however, in the event that a Change in Control occurs within one year following an amendment to the Plan that would adversely affect the rights or potential rights of Participants, the amendment will not be effective. In anticipation of or on or following a Change in Control, the Plan shall no longer be subject to amendment, change, substitution, deletion, revocation or termination in any respect which adversely affects the rights of Participants without the consent of each Participant so affected. For the avoidance of doubt, removal of a Participant as a Participant (other than as a result of the Participant ceasing to be an Employee) or a decrease in the Participant’s Tier Level shall be deemed to be an amendment of the Plan which adversely affects the rights of the Participant.

7.3 Form of Amendment. The form of any amendment or termination of the Plan shall be a written instrument signed by a duly authorized officer or officers of the Company, certifying that the amendment or termination has been approved by the Board. An amendment of the Plan in accordance with the terms hereof shall automatically effect a corresponding amendment to all Participants’ rights and benefits hereunder. A termination of the Plan shall in accordance with the terms hereof automatically effect a termination of all Participants’ rights and benefits hereunder.

7.4 Claims Procedure.

(a) A Participant may file a claim with respect to amounts asserted to be due hereunder by filing a written claim with the Committee specifying the nature of such claim in detail. The Committee shall notify the claimant within 60 days as to whether the claim is allowed or denied, unless the claimant receives written notice from the Committee prior to the end of the 60 day period stating that special circumstances require an extension of time for a decision on the claim, in which case the period shall be extended by an additional 60 days. Notice of the Committee’s decision shall be in writing, sent by mail to the Participant’s last known address and, if the claim is denied, such notice shall (i) state the specific reasons for denial, (ii) refer to the specific provisions of the Plan upon which such denial is based, and (iii) if applicable, describe any additional information or material necessary to perfect the claim, an explanation of why such information or material is necessary, and an explanation of the review procedure in Section 7.4(b).

- 12 -

(b) A claimant is entitled to request a review of any denial of his claim under Section 7.4(a). The request for review must be submitted to the Committee in writing within 60 days of mailing by the Committee of notice of the denial. Absent a request for review within the 60 day period, the claim will be deemed conclusively denied. The claimant or his representative shall be entitled to review all pertinent documents, and to submit issues and comments orally and in writing to the Committee. The review shall be conducted by the Committee, which shall afford the claimant a hearing and which shall render a decision in writing within 60 days of a request for a review, provided that, if the Committee determines prior to the end of such 60 day review period that special circumstances require an extension of time for the review and decision of the denial, the period for review and decision on the denial shall be extended by an additional 60 days. The claimant shall receive written notice of the Committee’s review decision, together with specific reasons for the decision and reference to the pertinent provisions of the Plan.

ARTICLE 8

MISCELLANEOUS

8.1 Legal Fees and Expenses. The Company shall reimburse all legal fees and related expenses (including the costs of experts, evidence and counsel) reasonably and in good faith incurred by a Participant if the Participant prevails on a material issue with respect to his or her claim for relief in an action by the Participant to obtain or enforce any right or benefit provided by this Plan.

8.2 Employment Status. This Plan does not constitute a contract of employment or impose on the Participant or the Company any obligation to retain the Participant as an Employee, to change the status of the Participant’s employment, or to change the Company’s policies regarding termination of employment.

8.3 Nature of Plan and Benefits. Participants and any other person who may have rights hereunder shall be mere unsecured general creditors of the Company with respect to a Severance Benefits due hereunder, and all amounts (other than fully insured benefits) shall be payable from the general assets of the Company.

8.4 Withholding of Taxes. The Company may withhold from any amount payable or benefit provided under this Plan such Federal, state, local, foreign and other taxes as are required to be withheld pursuant to any applicable law or regulation.

8.5 No Effect on Other Benefits. Severance Benefits shall not be counted as compensation for purposes of determining benefits under other benefit plans, programs, policies and agreements, except to the extent expressly provided therein or herein.

8.6 Validity and Severability. The invalidity or unenforceability of any provision of the Plan shall not affect the validity or enforceability of any other provision

- 13 -

of the Plan, which shall remain in full force and effect, and any prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

8.7 Successors. This Plan shall bind any successor of or to the Company, its assets or its businesses (whether direct or indirect, by purchase, merger, consolidation or otherwise), in the same manner and to the same extent that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not by the foregoing provision or by operation of law be bound by this Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the Company’s obligations under this Plan, in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. The term “Company,” as used in this Plan, shall mean the Company as hereinbefore defined and any successor or assignee to the business or assets which by reason hereof becomes bound by this Plan.

8.8 Assignment. This Plan shall inure to the benefit of and shall be enforceable by a Participant’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.
