(b) Settlement of the Released Claims Against Mirant. Subject to the provisions of Section 5(c):

(i) Pepco’s Class 3 Claim. On the Effective Date, the Mirant Settling Parties shall cause Pepco to receive, on account of (1) the claims released by Pepco on the Effective Date pursuant to Section 3(a), (2) the rejection and termination of the Back-to-Back Arrangement, and (3) the rejection and termination of the Assignment and Assumption Agreement, dated December 19, 2000, by and between Pepco and the Mirant Entities, an allowed Mirant Debtor Class 3 – Unsecured Claim (as defined in the Debtors’ Plan) (“Pepco’s Class 3 Claim”) against Old Mirant in such amount as will result in a total aggregate distribution to Pepco (the “Pepco Distribution”), net of any reasonable actual transaction commissions, fees and expenses incurred by Pepco under the Liquidation Agreement, having a value of Five Hundred Twenty Million Dollars ($520,000,000.00) (subject to adjustment as provided in Sections 5(c) and 5(f), the “Pepco Distribution Amount”). The Pepco Distribution shall be paid in up to Eighteen Million (18,000,000) shares of common stock of New Mirant (the “Pepco Shares”) and/or in cash as provided in Sections 2(b)(ii) and 2(b)(iii). Pepco’s Class 3 Claim shall not be disallowed, reduced or subordinated for any reason whatsoever, and is accordingly not subject to any offset or reduction for any reason, including, but not limited to, under Section 502(d) of the Bankruptcy Code, and none of the Mirant Settling Parties shall take any action that is inconsistent with the foregoing. Pepco shall not sell, assign, hypothecate or otherwise transfer Pepco’s Class 3 Claim without New Mirant’s prior written consent.

(ii) Liquidation of the Pepco Shares. The Pepco Shares will be delivered by New Mirant to Pepco as an initial distribution of 13.5 million shares of common stock of New Mirant (the “First Distribution”) followed by a second distribution of shares of common stock of New Mirant (the “Second Distribution”) after the liquidation of the First Distribution. New Mirant shall notify Pepco within two (2) business days after the Effective Date of the number of shares to be distributed as part of the Second Distribution, with the number of shares to be determined by New Mirant so as to be reasonably likely to minimize any Shortfall Payment (as hereinafter defined) or Excess Payment (as hereinafter defined) when liquidated and combined with the proceeds from the liquidation of the First Distribution. No later than twenty (20) business days following the Effective Date, Pepco shall negotiate with at least four reputable banks, two of which will be banks identified by New Mirant, to develop a form of agreement for the liquidation of the Pepco Shares (the “Liquidation Agreement”) that is acceptable to Pepco and at least two of the banks, at least one of which is a bank identified by New Mirant, and shall provide a copy of the form of Liquidation Agreement to New Mirant, provided that Pepco shall use commercially reasonable efforts to promptly provide New Mirant with drafts of any proposed or suggested Liquidation Agreement as such drafts are exchanged during the course of negotiations between Pepco and a proposed counterparty bank. The Liquidation Agreement shall provide for the Pepco Shares to be sold by Pepco to the counterparty bank or banks as a block trade of the Pepco Shares, with the objective of maximizing the net proceeds received by Pepco from the liquidation of the Pepco Shares. The Liquidation Agreement shall further provide that the 13.5 million shares that comprise the First Distribution shall be transferred from Pepco to the counterparty bank or banks on or before a specified settlement date set forth in the

executed Liquidation Agreement and that the shares comprising the Second Distribution shall be sold from Pepco to a counterparty bank or banks as a forward sale with delivery to occur upon Pepco’s receipt of the Second Distribution from New Mirant. Within one business day following New Mirant’s receipt of the form of Liquidation Agreement acceptable to Pepco and at least two of the banks, at least one of which is a bank identified by New Mirant, New Mirant shall instruct its transfer agent to cause Pepco to receive the First Distribution as soon as reasonably possible thereafter. As soon as reasonably possible after receiving the First Distribution, Pepco shall obtain competitive bids from the banks that found the form of Liquidation Agreement acceptable, select the bank or banks with whom it will enter into the Liquidation Agreement on the basis of the competitive bids, enter into the Liquidation Agreement and liquidate the First Distribution pursuant to the Liquidation Agreement. Within one business day after Pepco informs New Mirant in writing that Pepco has liquidated the First Distribution and that the bank or banks purchasing the Pepco Shares that comprised the First Distribution have represented to Pepco that it or they can receive the shares comprising the Second Distribution without any such bank holding five percent or more of the common stock of New Mirant, New Mirant shall instruct its transfer agent to cause Pepco to receive the Second Distribution as soon as reasonably possible thereafter, which Second Distribution Pepco shall also liquidate pursuant to the Liquidation Agreement. Prior to Pepco’s receipt from Mirant of and after Pepco’s liquidation of any Pepco Shares, Pepco shall not directly or indirectly exercise or control the exercise of any voting or other shareholder rights with respect to such Pepco Shares, and, upon Pepco’s transfer of the Pepco Shares comprising the First Distribution and the Second Distribution to the bank or banks pursuant to the Liquidation Agreement, Pepco shall not hold or control any shares of common stock of New Mirant.

(iii) Excess Payment; Shortfall Payment. If the sum of the proceeds that Pepco receives from the bank or banks under the Liquidation Agreement as a result of the liquidation of the Pepco Shares, net of any reasonable actual transaction commissions, fees and expenses incurred by Pepco under the Liquidation Agreement, plus the amount of any cash payments made to Pepco pursuant to Section 5(e) of this Agreement is less than the Pepco Distribution Amount or more than the Pepco Distribution Amount, Pepco shall immediately inform New Mirant of the amount of the difference between such sum and the Pepco Distribution Amount. Within two (2) business days of Pepco’s informing New Mirant of the difference between such sum and the Pepco Distribution Amount, (1) if the sum of the net proceeds that Pepco receives from the liquidation of the Pepco Shares plus the amount of any cash payments made to Pepco pursuant to Section 5(e) of this Agreement is greater than the Pepco Distribution Amount, Pepco shall provide New Mirant with an amount of cash equal to the difference between such sum and the Pepco Distribution Amount (the “Excess Payment”), or (2) if the sum of the net proceeds that Pepco receives from the liquidation of the Pepco Shares plus the amount of any cash payments made to Pepco pursuant to Section 5(e) of this Agreement is less than the Pepco Distribution Amount, New Mirant shall provide Pepco with an amount of cash equal to the difference between such sum and the Pepco Distribution Amount (the “Shortfall Payment”), provided that the Shortfall Payment shall be credited with and reduced by such portion of any payment that otherwise would be due to MPP under Section 5(g) as does not exceed the Shortfall Payment. Notwithstanding anything else in this Agreement, in no event shall New Mirant be obligated to distribute in excess of 18 million shares of New Mirant common stock to Pepco on account of Pepco’s Class 3 Claim; provided that any shortfall between (A) the sum of the net proceeds received by Pepco from the liquidation of the Pepco Shares actually distributed to Pepco plus the amount of any cash payments made to Pepco pursuant to Section 5(e) of this Agreement and

(B) the Pepco Distribution Amount shall be paid as a Shortfall Payment pursuant this Section 2(b)(iii); and provided further that the total number of Pepco Shares as well as the number of shares of common stock of New Mirant to be distributed as part of the First Distribution and the Second Distribution shall be appropriately adjusted for any stock splits occurring after the date of this Agreement. Pepco and New Mirant may modify the procedures for the liquidation of the Pepco Shares by written agreement. Except for the Pepco Distribution, Pepco shall not be entitled to any distribution under the Debtors’ Plan with respect to Pepco’s Class 3 Claim.

(iv) Allocation of the Pepco Distribution Amount. Of the Pepco Distribution Amount, (1) Four Hundred Fifty Million Dollars ($450,000,000.00) shall be allocated to Pepco’s damages resulting from Old Mirant’s rejection of the Back-to-Back Arrangement, and (2) Seventy Million Dollars ($70,000,000.00) shall be allocated as follows: (A) Fifteen Million Dollars ($15,000,000.00) shall be allocated to claims asserted by Pepco in connection with the Local Area Support Agreement by and between Pepco and Mirant Potomac River, LLC, f/k/a Southern Energy Mirant Potomac River, LLC (“Mirant Potomac”), dated December 19, 2000 (the “LASA”), occasioned by Mirant Potomac’s suspension of operations of the Potomac River Plant in 2005, (B) One Hundred Thousand Dollars ($100,000.00) shall be allocated to the Bankruptcy Court’s award of that amount to Pepco resulting from Old Mirant’s objection to Pepco’s receiving a distribution on its allowed claim under the TPA Settlement prior to resolution of claims filed by Old Mirant against Pepco, and (C) the remainder of the $70,000,000.00 shall satisfy the Pre-Petition Claim, claims arising from the rejection of the Assumption/Assignment Agreements, the administrative claim related to execution of certificates in connection with pollution control bonds pursuant to Section 7.12 of the APSA, internal and external legal fees and expenses incurred in connection with the Case, including the legal fees and expenses incurred by SMECO, other additional internal and external expenses incurred in connection with the Case, Pepco’s economic costs and losses incurred as a result of and/or in connection with the Case, and all Released Claims Against Mirant not otherwise listed in this Section 2(b)(iv).

(v) Certain Representations and Warranties by New Mirant. New Mirant represents and warrants to each of the Pepco Settling Parties that:

(1) the Pepco Shares delivered by New Mirant to Pepco pursuant to Section 2(b)(ii) will be duly authorized, validly issued, fully paid and nonassessable and will be free and clear of any liens or encumbrances of any kind except as may be created by the Pepco Settling Parties;

(2) the issuance of the Pepco Shares will not result in the violation of any federal or state law except for such violations as would not, individually or in the aggregate, have a material adverse affect on the business or results of operations of New Mirant and that would not materially hinder or impair the ability of New Mirant to issue the Pepco Shares pursuant hereto; and

(3) the reports filed with or furnished to the Securities and Exchange Commission by New Mirant pursuant to the Securities Exchange Act of 1934, as amended, (A) since January 1, 2006, through the date of this Agreement, did not, as of their respective dates, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (B) subsequent to the date of this Agreement through the date on which the sales of the Pepco Shares by the Pepco Settling Parties pursuant to the Liquidation

Potomac Electric Power Co., et al., No. 05-10038 (5th Cir.), and Potomac Electric Power Co. v. Mirant Corp., et al., No. 05-10419 (5th Cir.), pending the entry of a Final Order approving this Settlement Agreement, which Final Order will result in the dismissal of those cases pursuant to Section 2(c) herein. If the Fifth Circuit does not enter the requested stay and rules on one or both of the cases identified in this Section 2(d), the Pepco Settling Parties and the Mirant Settling Parties further agree, regardless of the ruling or rulings of the Fifth Circuit, that they shall each be bound by the terms of this Settlement Agreement.

(e) Future Treatment of this Agreement, the Assumed APSA, and the Other Assumed Agreements. The Mirant Settling Parties and the Pepco Settling Parties agree and acknowledge that:

(i) the standard of review for any termination of or changes to any portion of the Assumed APSA, the Back-to-Back Arrangement (if assumed pursuant to Section 5(c)), the Other Assumed Agreements or the SMECO Agreements over which the Federal Energy Regulatory Commission (“FERC”) has jurisdiction, whether such changes are proposed by Pepco, MPP, any of the other Mirant Settling Parties, a non-party, or FERC acting sua sponte, shall be the “public interest” standard of review set forth in United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332 (1956), and Federal Power Commission v. Sierra Pacific Power Co., 350 U.S. 348 (1956);

(ii) the standard of review for any proposed rejection of the Assumed APSA, the Back-to-Back Arrangement (if assumed pursuant to Section 5(c)), the Other Assumed Agreements, or the SMECO Agreements, or any portion of those agreements, by any of the

Pepco Settling Parties or any of the Mirant Settling Parties in bankruptcy proceedings shall be the “balancing of the equities” test suggested in In re Mirant Corp., 378 F.3d 511 (5th Cir. 2004);

(iii) As a result of the releases provided by the Pepco Settling Parties herein, Mirant Potomac shall have no obligation under the LASA to fund the transmission facilities upgrades being implemented by Pepco as a result of the suspension of operations at the Potomac River Plant that began in August 2005, including the transmission facilities upgrades approved by the DC Public Service Commission in March 2006. Pepco and Mirant Potomac further agree that Pepco shall (1) give Mirant Potomac 30 days’ prior written notice of any planned outage of transmission facilities that would cause an Abnormal Condition (as defined in the LASA) to occur, and (2) give Mirant Potomac prompt written notice upon the occurrence of any unplanned outages of such transmission facilities. Pepco shall comply with the notification requirements under the Department of Energy Order EO-05-01; and

(iv) Notwithstanding anything to the contrary herein (1) if Old Mirant rejects the Back-to-Back Arrangement pursuant to this Agreement, a breach of any of the Assumed APSA, the Back-to-Back Arrangement, the Other Assumed Agreements or the SMECO Agreements, respectively, shall not entitle the non-defaulting party to terminate, suspend performance under, or exercise any other right or remedy under or with respect to any of the other such agreements, and (2) if, however, New Mirant elects to have the Back-to-Back Arrangement assumed and assigned by Old Mirant pursuant to Section 5(c), nothing in this Agreement shall prejudice any claim or argument by the Pepco Settling Parties that the Assumed APSA, the Back-to-Back Arrangement, and the Other Assumed Agreements constitute a single non-severable agreement, the material breach of which would entitle the Pepco Settling Parties to suspend or terminate all performance by the Pepco Settling Parties thereunder, or any defense of the Mirant Settling Parties to any such claim or argument.

(b) Each of the Mirant Settling Parties and the Pepco Settling Parties shall use commercially reasonable efforts to cause the Effective Date to occur promptly, including using commercially reasonable efforts to obtain, on an expedited basis, approval of this Agreement pursuant to Rule 9019 of the Federal Rules of Bankruptcy Procedure by the Applicable Court. In addition, each of the Pepco Settling Parties and the Mirant Settling Parties shall support this Agreement in any communications, whether oral or written, as to the matters that are the subject of this Agreement with any court of competent jurisdiction, FERC, the Public Service Commission of Maryland, the Public Service Commission of the District of Columbia, the People’s Counsel for the State of Maryland, the People’s Counsel for the District of Columbia, and all other applicable regulatory agencies.

(c) Notwithstanding anything herein to the contrary, prior to the Election Termination Date, if a Share Price Trigger occurs, New Mirant may elect, by giving Pepco written notice by the tenth business day after the first occurrence of a Share Price Trigger, that the Back-to-Back Arrangement not be rejected and terminated. If New Mirant so elects, then (i) Section 2(a)(ix) will be void and of no effect, (ii) pursuant to Section 365 of the Bankruptcy Code and Section 14.5 of the Debtors’ Plan, Old Mirant will assume the Back-to-Back Arrangement and assign the Back-to-Back Arrangement to MPP effective as of the Effective Date, (iii) MPP will accept the assignment of the Back-to-Back Arrangement, cure all defaults under the Back-to-Back Arrangement (other than defaults that constitute Released Claims Against Mirant) and agree to discharge and otherwise perform when due, without recourse against Pepco, all obligations and liabilities due to or for the benefit of Pepco thereunder (other than obligations that constitute Released Claims Against Mirant), (iv) New Mirant shall unconditionally guaranty MPP’s performance of all obligations due to or for the benefit of Pepco under the Back-to-Back Arrangement pursuant to, and on or prior to the Effective Date shall enter into, a guaranty agreement substantially in the form attached hereto as Exhibit 2(a)(iv), (v) only MPP, and New Mirant as guarantor, shall have any obligations under the Back-to-Back Arrangement, and the other Mirant Settling Parties will have no liability with respect to the Back-to-Back

If New Mirant does not timely elect that the Back-to-Back Arrangement not be rejected and terminated as provided in the first sentence of this Section 5(c) following the first occurrence of a Share Price Trigger, then Mirant shall be deemed to have waived any right to make such election and this Section 5(c) will be void and of no effect.

(d) If the Approval Order is appealed, the Mirant Settling Parties shall continue to perform all of their obligations under the APSA, the Back-to-Back Arrangement, the Other Assumed Agreements, the SMECO Agreements, and the Assumption/Assignment Agreements in accordance with the provisions of Sections 14.5 and 14.8 of the Debtors’ Plan until the Approval Order becomes a Final Order or there is a Final Order allowing the Mirant Settling Parties to cease performance of those obligations.

If the Approval Order becomes a Final Order, (1) New Mirant shall distribute Pepco Shares to Pepco in accordance with the provisions of Section 2(b)(ii) as if the Advance Payment had not been made, (2) Pepco shall liquidate the Pepco Shares in accordance with the provisions of Section 2(b)(ii), and (iii) the Advance Payment shall be included as a cash payment made to Pepco on account of the Pepco Distribution in the calculation of any Shortfall Payment or Excess Payment.

(g) Further, if (i) the Approval Order becomes a Final Order, either after an appeal or otherwise and (ii) the Back-to-Back Arrangement is not assumed pursuant to Section 5(c),

Pepco, within two (2) business days after receiving the full consideration due to Pepco under this Agreement on account of the Pepco Distribution, shall pay MPP an amount equal to the aggregate amount of any payments made by the Mirant Settling Parties on account of the Back-to-Back Arrangement for energy, capacity or other services delivered after May 31, 2006, less any portion of such amount credited against the Shortfall Payment pursuant to Section 2(b)(iii)(2).

Exhibit 2(a)(iv) - Form of New Mirant Guaranty

GUARANTEE AGREEMENT

THIS GUARANTEE AGREEMENT (this “Agreement”), dated as of , 2006, by and between Mirant Corporation, a Delaware corporation (“Guarantor”), and Potomac Electric Power Company, a District of Columbia and Virginia corporation (together with its successors and permitted endorsees, transferees and assigns, “Pepco”). Guarantor and Pepco are referred to herein individually as a “Party” and collectively as the “Parties.” Capitalized terms used herein and defined in the Settlement Agreement (as defined below) have the meanings set forth for such terms in the Settlement Agreement.

WHEREAS, Mirant and Pepco, among others, are parties to that certain Settlement Agreement and Release dated as of May 30, 2006 (the “Settlement Agreement”) pursuant to which the parties thereto agreed to settle, on the terms and conditions contained therein, certain disputes, including disputes with respect to the APSA, the Back-to-Back Arrangement, the Other Assumed Agreements, the SMECO Agreements and the Assumed Obligations.

WHEREAS, pursuant to and subject to the terms and provisions of the Settlement Agreement, MPP has assumed the Assumed APSA [and the Back-to-Back Arrangement](1), certain Mirant Settling Parties have assumed or accepted the assignment of the Other Assumed Agreements and have assumed the Assumed Obligations arising under the Other Assumed Agreements, Mirant Chalk Point, LLC has assumed the SMECO Agreements and assumed the Assumed Obligations arising under the SMECO Agreements, and MPP has assumed the Assumed Obligations not arising under the Other Assumed Agreements or the SMECO Agreements.

WHEREAS, pursuant to the Settlement Agreement, Mirant has agreed to guarantee the payment and performance of the obligations of the other Mirant Settling Parties under the Assumed APSA, [the Back to Back Arrangement],(2) the Other Assumed Agreements, the SMECO Agreements and the Assumed Obligations (collectively, the “Underlying Agreements”) pursuant to this Agreement.

NOW, THEREFORE, the Parties agree, effective as of the Effective Date, as follows:

SECTION 1. Purpose and Intent. IT IS THE PURPOSE AND INTENT OF THIS AGREEMENT THAT THE OBLIGATIONS OF GUARANTOR UNDER THIS AGREEMENT ARE IRREVOCABLE, ABSOLUTE AND UNCONDITIONAL, PRESENT AND CONTINUING UNDER ANY AND ALL CIRCUMSTANCES UNTIL TERMINATED IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT.

SECTION 2. Guarantee. Guarantor absolutely, irrevocably and unconditionally guarantees, as a primary obligor and not merely as a surety, (a) the due and punctual payment to Pepco of (i) each payment required to be made by the other Mirant Settling Parties under the

(1) If applicable.

(2) Id.

Underlying Agreements when and as due, whether at maturity or by reason of acceleration or otherwise and at all times thereafter, including payments in respect of reimbursement of disbursements and interest thereon and (ii) all other monetary obligations, including indemnities, fees, costs and expenses, whether primary, secondary, direct, contingent, fixed or otherwise (including monetary obligations incurred during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, regardless of whether allowed or allowable in such proceeding), of the other Mirant Settling Parties under the Underlying Agreements (all such obligations referred to in this clause (a) being collectively referred to as the “Monetary Obligations”) and (b) the due and punctual performance and observance of, and compliance with, all covenants, agreements, obligations and liabilities of the other Mirant Settling Parties under the Underlying Agreements or the Settlement Agreement (all such obligations referred to in the preceding clauses (a) and (b) and any extensions, renewals or replacements thereof being collectively referred to as the “Obligations”).

SECTION 3. Payment of Costs. Guarantor agrees to pay and reimburse Pepco for all reasonable costs, legal expenses and attorneys’ and paralegals’ fees of every kind (excluding those costs, expenses and fees of attorneys and paralegals who may be employees of Pepco), paid by, or incurred by or on behalf of, Pepco in enforcing its rights under this Agreement, provided that the Guarantor shall not be liable for any expenses of Pepco if no payment or performance is determined to be due from Guarantor under this Agreement.

SECTION 4. Waiver of Notice and Defenses. To the fullest extent permitted by applicable law, Guarantor hereby expressly, absolutely, unconditionally and irrevocably waives all notices whatsoever with respect to this Agreement, with respect to the Underlying Agreements, with respect to the Settlement Agreement or with respect to the Obligations, including, without limitation, presentment to, demand of payment from and protest, dishonor, default or nonpayment to the other Mirant Settling Parties or any other person of any of the Obligations, and notice of acceptance of its guarantee. To the fullest extent permitted by applicable law, the obligations of Guarantor hereunder shall not be affected by (a) the failure of Pepco to assert any claim or demand or to enforce or exercise any right or remedy against the other Mirant Settling Parties in respect of the Obligations or any delay in connection therewith, or (b) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, this Agreement not made in accordance with Section 13 of this Agreement.

SECTION 5. Continuing Guarantee of Payment and Performance. Guarantor further agrees that its guarantee contained herein constitutes a continuing guarantee of payment and performance when due, and not of collection, and therefore Pepco shall not be required (although it is entitled, at its option) to prosecute collection, enforcement or other remedies against the other Mirant Settling Parties, any other guarantor or any other person, before calling on Guarantor for payment and performance of the Obligations. Guarantor further waives any right to require that any resort be had by Pepco (although it is entitled, at its option) to any security.

SECTION 6. Discharge or Diminishment of Guarantee.

(a) The obligations of Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination, or be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever, or otherwise be affected, for any reason (other than the performance in full of all Obligations, including the indefeasible payment in full in cash of all Monetary Obligations, and the termination of all the Obligations), including, without limitation:

(i) any claim of waiver, release, surrender, alteration or compromise of any of the Obligations;

(ii) any claim or defense of statute of limitations, statute of frauds, fraud, incapacity, minority or usury;

(iii) the invalidity, illegality or unenforceability of the Obligations or the genuineness, validity or regularity of the Underlying Agreements or the Settlement Agreement;

(iv) the occurrence or continuance of any event of bankruptcy, reorganization, insolvency, receivership or other similar proceeding with respect to the other Mirant Settling Parties or any other person (for purposes hereof, “person” means any individual, partnership, limited liability company, joint venture, corporation, trust, unincorporated organization or Governmental Authority), or the dissolution, liquidation or winding up of the other Mirant Settling Parties or any other person;

(v) any permitted assignment or other permitted transfer of this Agreement or any rights hereunder by Pepco;

(vi) any sale, transfer or other disposition by Guarantor of any direct or indirect interest it may have in the other Mirant Settling Parties or any other change in ownership or control of the other Mirant Settling Parties;

(vii) the absence of any notice to, or knowledge on behalf of, Guarantor of the existence or occurrence of any of the matters or events set forth in the foregoing clauses; or

(viii) any other action or circumstance that might otherwise constitute a legal or equitable discharge or defense of Guarantor from performance of the obligations set forth herein (other than the performance in full of all Obligations, including the indefeasible payment in full in cash of all Monetary Obligations, and the termination of all the Obligations).

(b) Without limiting the generality of the foregoing, the obligations of Guarantor hereunder shall not be discharged or impaired or otherwise affected by the failure of Pepco to assert any claim or demand or to enforce its rights under this Agreement, the Underlying Agreements or the Settlement Agreement, by any waiver or modification of any

provision thereof (except a waiver or modification made in accordance with Section 13 hereof), by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of Guarantor or that would otherwise operate as a discharge of Guarantor as a matter of law or equity (other than the performance in full of all Obligations, including the indefeasible payment in full in cash of all Monetary Obligations, and the termination of all the Obligations).

(c) In furtherance and not in limitation of the foregoing, Guarantor authorizes Pepco, without notice, demand or additional reservation of rights against Guarantor and without affecting Guarantor’s obligations hereunder, from time to time: (1) to renew, refinance, modify, subordinate, extend, increase, accelerate, or otherwise change the time for payment of, the terms of or the interest on the Obligations or any part thereof; (2) to accept collateral from any person or entity and hold collateral for the payment of the Obligations or any part thereof, and to exchange, enforce, refrain from enforcing or release such collateral or any part thereof; (3) to accept and hold any indorsement or guarantee of payment of the Obligations or any part thereof or any negotiable instrument or other writing intended by any party to create an accord and satisfaction with respect to the Obligations or any part thereof, and to discharge, terminate, release, substitute, replace or modify any such obligation of any such indorser or guarantor, or any person or entity who has given any security interest in any collateral as security for the payment of the Obligations or any part thereof, or any other person or entity in any way obligated to pay the Obligations or any part thereof, and to enforce, or refrain from enforcing, compromise or modify, the terms of any obligation of such indorser, guarantor, person or entity; (4) to dispose of any and all collateral securing the Obligations in any commercially reasonable manner as Pepco, in its sole discretion, may deem appropriate, and to direct the order or manner of such disposition and the enforcement of any and all indorsements and guarantees relating to the Obligations or any part thereof as Pepco, in its sole discretion, may determine; (5) subject to the terms and provisions of the Underlying Agreements and the Settlement Agreement, to determine the manner, amount and time of application of payments and credits, if any, to be made on all or any part of any component or components of the Obligations (whether principal, interest, costs and expenses, or otherwise); (6) to take advantage or refrain from taking advantage of any security or accept or make or refrain from accepting or making any compositions or arrangements when and in such manner as Pepco, in its sole discretion, may deem appropriate; and (7) to generally do or refrain from doing any act or thing which might otherwise, at law or in equity, release the liability of Guarantor as a guarantor or surety in whole or in part, and in no case shall Pepco be responsible, or shall the Guarantor be released in whole or in part, for any act or omission in connection with Pepco having sold any collateral at less than its value, providing that the collateral is sold in a commercially reasonable manner.

SECTION 7. Defenses Waived. To the fullest extent permitted by applicable law, Guarantor waives any defense based on or arising out of the unenforceability of the Obligations or any part thereof from any cause. Pepco may compromise or adjust any part of the Obligations, make any other accommodation with the other Mirant Settling Parties or exercise any other right or remedy available to it against the other Mirant Settling Parties, without affecting or impairing in any way the liability of Guarantor hereunder except to the extent that all the Obligations have been fully and finally performed, including the indefeasible payment in full of all Monetary Obligations, and terminated. To the fullest extent permitted by applicable law,

Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of Guarantor against the other Mirant Settling Parties or any security. Guarantor waives each right and all defenses to which it may be entitled under applicable law as in effect or construed from time to time.

SECTION 8. Representations and Warranties of Guarantor. Guarantor represents and warrants to Pepco as follows:

(a) Organization. Guarantor is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as is now being conducted.

(b) Authority Relative to this Agreement. Guarantor has all necessary corporate power and authority to execute and deliver this Agreement and to perform its obligations hereunder. The execution and delivery by Guarantor of this Agreement and performance by Guarantor of its obligations hereunder have been duly and validly authorized and no other corporate proceedings on the part of Guarantor are necessary to authorize this Agreement and the performance by Guarantor of its obligations hereunder. This Agreement has been duly and validly executed and delivered by Guarantor and this Agreement constitutes a valid and binding agreement of Guarantor, enforceable against Guarantor in accordance with its terms.

(i) Neither the execution and delivery of this Agreement by Guarantor nor performance by Guarantor of its obligations hereunder will (i) conflict with or result in any breach of any provision of the organizational or governing documents or instruments of Guarantor, (ii) result in a default (or give rise to any right of termination, cancellation or acceleration) under any of the terms, conditions or provisions of any note, bond, mortgage, indenture, license, agreement, lease or other instrument or obligation to which Guarantor or any of its subsidiaries is a party or by which any of their respective assets may be bound, or (iii) violate any order, writ, injunction, decree, statute, rule or regulation applicable to Guarantor, or any of its assets, except in the case of clauses (ii) and (iii) for such failures to obtain a necessary consent, defaults and violations which would not, individually or in the aggregate, have a material adverse effect on the ability of Guarantor to discharge its obligations under this Agreement (a “Guarantor Material Adverse Effect”).

(ii) No declaration, filing or registration with, or notice to, or authorization, consent or approval of any governmental authority is necessary for performance by Guarantor of its obligations hereunder, other than such declarations, filings, registrations, notices, authorizations, consents or approvals which, if not obtained or made would not, individually or in the aggregate, have a Guarantor Material Adverse Effect.

SECTION 9. Agreement to Perform and Pay; Subordination. In furtherance of the foregoing and not in limitation of any other right that Pepco has at law or in equity against Guarantor by virtue hereof, upon the failure of any of the other Mirant Settling Parties to perform or pay any Obligation when and as the same shall become due, Guarantor hereby promises to and will forthwith, as the case may be, (a) perform, or cause to be performed, such unperformed Obligations and (b) pay, or cause to be paid, to Pepco in cash the amount of such unpaid Monetary Obligations. Upon payment by Guarantor of any sums to Pepco as provided above, all rights of Guarantor against the other Mirant Settling Parties arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all respects be subordinate and junior in right of payment to the prior indefeasible payment in full in cash of all the Monetary Obligations. If any amount shall erroneously be paid to Guarantor on account of (i) such subrogation, contribution, reimbursement, indemnity or similar right or (ii) any such indebtedness of the other Mirant Settling Parties¸ such amount shall be held in trust for the benefit of Pepco and shall forthwith be paid to Pepco to be credited against the payment of the Monetary Obligations.

SECTION 10. Information. Guarantor assumes all responsibility for being and keeping itself informed of the other Mirant Settling Parties’ financial condition and assets, and of all other circumstances bearing upon the risk of nonperformance of the Obligations (including the nonpayment of Monetary Obligations) and the nature, scope and extent of the risks that Guarantor assumes and incurs hereunder, and agrees that Pepco does not have any duty to advise Guarantor of information known to it regarding such circumstances or risks.

SECTION 11. Termination and Reinstatement.

(a) Notwithstanding any provision to the contrary herein, this Agreement and the guarantee made hereunder shall terminate for all purposes upon the termination of the Settlement Agreement pursuant to Section 7 of the Settlement Agreement.

(b) Subject to Section 11(a) above and Section 11(c) below, the guarantee made hereunder shall remain in full force and effect until, and shall terminate when, all the Obligations have been (i) finally and irrevocably performed in full, including the indefeasible payment in full in cash of the Monetary Obligations, and (ii) terminated.

(c) Notwithstanding Section 11(b), if at any time any payment, or any part thereof, of any Obligation is subsequently recovered from, rescinded or is restored by Pepco, whether upon the bankruptcy, dissolution, reorganization, arrangement, or liquidation proceedings (or proceedings similar thereto) of the other Mirant Settling Parties or Guarantor or for any other reason, this Agreement and all of Guarantor’s obligations under this Agreement shall continue to be effective or shall be reinstated, as the case may be, as though such payment had not been made. Except in the case of a termination pursuant to Section 11(a) above, the provisions of this Section 11(c) shall survive termination of the guarantee made hereunder or this Agreement.

SECTION 12. Assignment; No Third Party Beneficiaries. This Agreement and all of the provisions hereunder shall be binding upon and inure to the benefit of the Parties and their

respective successors (including, without limitation, any entity to which all or a substantial part of the business or assets of such Party shall have been transferred, including a debtor in possession under the Bankruptcy Code, and any entity into or with which such Party shall have been merged, consolidated, reorganized, or absorbed) and permitted assigns. Nothing herein express or implied will give or be construed to give any person other than the Parties any legal or equitable rights hereunder. Neither this Agreement nor any of the rights, interests and obligations hereunder shall be assigned by Guarantor, including by operation of law, without the prior written consent of Pepco; provided, however, that no assignment or transfer of rights or obligations by Guarantor shall relieve it from the full liabilities and the full financial responsibility set forth in this Agreement, unless and until the transferee or assignee shall agree in writing to assume such obligations and duties and Pepco has consented in writing to such assumption. Pepco may assign any of (including a portion of) its rights hereunder to any assignee or transferee of the Underlying Agreements without the consent of Guarantor; provided that such assignment or transfer of the Underlying Agreements is not effected in violation of the terms of the Underlying Agreements.

SECTION 13. Amendment and Modification; Extension; Waiver. Except with respect to assignments effected in accordance with Section 12, this Agreement may be amended, modified or supplemented only by an instrument in writing signed on behalf of each of the Parties. Any agreement on the part of a Party to any extension or waiver in respect of this Agreement shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of a Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

SECTION 14. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the District of Columbia (regardless of the laws that might otherwise govern under applicable principles of conflicts of law).

SECTION 15. Notices. All notices and other communications hereunder shall be in writing and shall be deemed given (as of the time of delivery or, in the case of a telecopied communication, of the times of confirmation) if delivered personally, telecopied (which is confirmed) or sent by overnight courier (providing proof of delivery) to the Parties at the following addresses (or at such other address for a Party as shall be specified by like notice):

(a) Each of the Parties irrevocably submits to the exclusive jurisdiction of (i) the Superior Court of the District of Columbia and (ii) the United States District Court for the District of Columbia for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each of the Parties agrees to commence any action, suit or proceeding relating hereto either in the United States District Court for the District of Columbia or, if such suit, action or proceeding may not be brought in such court for jurisdictional reasons, in the Superior Court of the District of Columbia. Each of the Parties further agrees that service of process, summons, notice or document by hand delivery or U.S. registered mail at the address specified for such Party in Section 15 (or such other address specified by such Party from time to time pursuant to Section 15) shall be effective service of process for any action, suit or proceeding brought against such Party in any such court. Each of the Parties irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in (i) the Superior Court of the District of Columbia and (ii) the United States District Court for the District of Columbia and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

(b) The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to equitable relief, including without limitation, an injunction or injunctions to prevent breaches of this Agreement and to specifically enforce the terms and provisions of this Agreement, this being in addition to any other remedy to which they are justly entitled to, whether at law or in equity.

SECTION 17. Effectiveness; Counterparts. This Agreement shall become effective as of the Effective Date. This Agreement may be executed in two counterparts, each of which shall be deemed an original, but both of which together shall constitute one and the same instrument.

SECTION 18. Rules of Interpretation. When a reference is made in this Agreement to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation” or equivalent words. The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto or thereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument, statute, regulation, rule or order defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument, statute, regulation, rule or order as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes, regulations, rules or orders) by succession of comparable successor statutes, regulations, rules or orders and references to all attachments thereto and instruments incorporated therein. References to a person are also to its permitted successors and assigns. Each Party acknowledges that it has been represented by counsel in connection with the review and execution of this Agreement and, accordingly, there shall be no presumption that this Agreement or any provision hereof be construed against the Party that drafted this Agreement.

SECTION 19. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

SECTION 20. Entire Agreement. This Agreement is intended by the Parties to be the final, complete and exclusive expression of the agreement between Guarantor and Pepco with respect to the guarantee of the Obligations. Guarantor expressly disclaims any reliance on any course of dealing or usage of trade or oral representations of Pepco, including, without limitation, representations to enter into any other agreement with the other Mirant Settling Parties or Guarantor.

IN WITNESS WHEREOF, this Guarantee Agreement has been duly executed and delivered by the Parties as of the date first above written and is effective as of the Effective Date.

The Settlement Agreement must be approved by the Bankruptcy Court and/or the District Court in Mirant’s bankruptcy proceedings by final order or orders to become effective.(3) On May 30, 2006, the parties filed motions in the Bankruptcy Court and District Court, pursuant to Federal Rule of Bankruptcy Procedure 9019, seeking such approval. The parties are hopeful that the lower courts will approve the Settlement Agreement.

(3) The district court has withdrawn the reference to the bankruptcy court for a number of the pending disputes between the parties.

6. Accordingly, Mirant and PEPCO file this Joint Motion for Stay of Pending Appeals and request that the Court stay further action on the Appeals pending approval of the Settlement Agreement by the Bankruptcy Court and/or the District Court by final order or orders. In the interim, the parties will keep the Court apprised regarding the status of the Rule 9019 motions. Once the order or orders approving the Settlement Agreement become final, the parties will file a joint motion to dismiss the Appeals.

7. Counsel for Mirant and PEPCO have conferred with counsel for FERC regarding the relief requested in this joint motion. Counsel for FERC has indicated that FERC does/does not oppose such relief.

CONCLUSION AND REQUEST FOR RELIEF
