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 audit. The accompanying statement of net assets available for benefits as of December 31, 2001 was audited by other auditors who have ceased operations. Those auditors expressed an unqualified opinion on the statement of net assets available for benefits as of December 31, 2001, in their report dated April 16, 2002. We conducted our audit 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 2002 financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the 2002 financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management as well as evaluating the overall 2002 financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the 2002 financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2002, and the changes in net assets available for benefits for the year then ended in conformity with accounting principles generally accepted in the United States of America. Our audit was performed for the purpose of forming an opinion on the 2002 basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2002 is presented for the purpose of additional analysis and is not a required part of the 2002 basic financial statements but is supplementary information required by Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the 2002 basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the 2002 basic financial statements taken as a whole. /s/KPMG LLP Atlanta, Georgia June 20, 2003 The following report of independent accountants is a copy of the report previously issued in connection with the Plan's 2001 financial statements on Form 11-K and has not been reissued by Arthur Andersen LLP, the former independent public accountants.

MIRANT SERVICES BARGAINING UNIT EMPLOYEE SAVINGS PLAN Notes to Financial Statements December 31, 2002 and 2001 (1) Summary of Significant Accounting Policies The following is a summary of significant accounting policies followed by the Mirant Services Bargaining Unit Employee Savings Plan (Plan) in preparing its financial statements. (a) Basis of Presentation The records of the Plan are maintained on the cash basis of accounting. The accompanying financial statements of the Plan have been prepared on the accrual basis of accounting and present the net assets available for benefits and changes in those net assets. 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 assets, liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. (b) Investments Investments in mutual funds and common stocks are stated at fair value based on quoted market prices or as determined by T. Rowe Price (Trustee). Investments in money market funds and loans to participants are stated at cost which approximates fair value. Securities transactions are accounted for on a trade date basis. Realized and unrealized investment gains and losses are included in net depreciation in fair value of investments in the accompanying statement of changes in net assets available for benefits. The Plan's investments include funds which invest in various types of investment securities and in various companies in various markets. Investment securities, generally, are exposed to several risks, such as interest rate, market, and credit risks. Due to the level of risk associated with the funds, it is reasonably possible that changes in the values of the funds will occur in the near term and such changes could materially affect the amounts reported in the financial statements and supplemental schedule. (c) Fair Value of Financial Instruments Investments in securities are stated at fair value. In addition, management of the Plan believes that the carrying amount of contribution receivable and accrued income is a reasonable approximation of the fair value due to the short-term nature of these instruments. (2) Plan Description The following description of the Plan provides only general information. Participants should refer to the summary plan description or the plan document for a more complete description of the Plan's provisions. (a) General The Plan is a defined contribution plan sponsored by Mirant Services, LLC (the Company), a wholly owned subsidiary of Mirant Corporation covering all regular full-time and part-time employees who are covered under a collective bargaining agreement. The Plan is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended. The Plan is administered by a benefits committee appointed by the Company. The benefits committee is responsible for the control, management, and administration of the Plan and the assets held in trust at the Trustee as of December 31, 2002 and 2001 and for the year ended December 31, 2002. On January 19, 2001, Southern Energy, Inc. announced, as part of its separation from Southern Company, that it was changing its name to Mirant Corporation. They began doing business as Mirant Corporation on January 22, 2001 and legally changed the name on February 26, 2001. The Company, noted above, is the employing company and plan sponsor. (b) Transferred Accounts and Merged Plans In December 2000, an affiliate of Southern Energy Resources, Inc. acquired certain assets of Potomac Electric Power Company (PEPCO). Pursuant to the acquisition, certain former employees of PEPCO who were eligible to participate in the PEPCO Bargaining Unit Retirement Savings Plan became eligible to participate in the Plan on December 19, 2000. The accounts of the former PEPCO employees who elected to a Voluntary Trust-to-Trust transfer were transferred into the Plan in early 2001 and were mapped to investments under the Plan with comparable investment objectives. The portions of the participants' accounts, which were invested in the PEPCO stock fund prior to the transfer, were invested in PEPCO common stock under the Plan. Effective May 1, 2001, the assets of the Southern Energy Resources, Inc. Bargaining Unit Savings Plan and the Southern Energy Resources, Inc. Savings Plan for Covered Employees were merged into the Plan and were mapped to investments under the Plan with comparable investment objectives. The portions of the participants' accounts, which were invested in the Southern Company stock fund prior to the transfer, were invested in Southern Company common stock under the Plan. (c) Contributions Participants may elect to contribute a percentage of their base compensation, on a pretax or after-tax basis, subject to certain limitations defined by the Plan, into any of the investment funds offered by the Plan. Participants may change their contribution percentages at any time. Participants may also contribute amounts representing eligible rollover distributions from other qualified retirement plans. The Plan has distinct characteristics for the various bargaining units noted above relative to eligibility and contributions (note 6). For all collectively bargained full-time and part-time employees who participate in a defined benefit plan with a 1.0 formula, as defined, the Company may elect to make a discretionary annual profit-sharing contribution to the Plan of the participant's eligible compensation to be allocated pro rata. Eligible compensation is the participant's actual base salary pay plus short-term incentive pay received during the period. The Company made discretionary contributions of $57,765 for the year ended December 31, 2002. (d) Participant Accounts and Vesting Each participant's account is credited with his contribution, the Company's matching contribution, and plan earnings (losses). Participants are immediately fully vested in these contributions. Discretionary profit-sharing contributions are 100% vested after five years of service. Amounts forfeited by participants who terminate from the Plan prior to being 100% vested are applied to reduce subsequent company contributions to the Plan. Investment income (loss), realized gains/losses, and the change in unrealized appreciation or depreciation on plan investments are credited to participants' accounts daily based on the proportion of each participant's account balance to the total account balance within each investment fund. A participant may direct his contributions into any of the investment fund options offered by the Plan. A participant may change his election options at any time. Company matching and discretionary profit-sharing contributions are initially invested in the Company stock fund until the participant elects to redirect the contributions to another investment fund. Participants with investments held in the Southern Company stock fund, PEPCO stock fund, and BP Amoco stock fund will have five years (until March 31, 2006) to liquidate their investment position in the stock and transfer the proceeds into other investment options within the Plan. These Plan investment options are considered frozen; therefore, no new contributions may be made into these options. There are no other restrictions on transferring in or out of any other investment options within the Plan. (e) Benefits Upon termination of service, death, or disability, a participant or his beneficiary may elect to receive an amount equal to the value of his account in a lump-sum distribution. If account balances are less than $5,000, participants will automatically receive a lump-sum payment. If a participant retires, he may elect to receive a lump-sum distribution or annual installments for a period not to exceed 20 years or life expectancy. Distributions upon termination of service, retirement, disability, or death are normally made in cash unless shares of common stock are requested. Under the terms of the Plan, participants may make hardship withdrawals from their accounts upon furnishing proof of hardship as specified in the Plan agreement. A participant may borrow the lesser of $50,000, less the highest outstanding loan balance in the previous 12 months, or 50% of his/her vested account balance, with a minimum loan amount of $1,000. Loans are repayable through payroll deductions over the respective term of the loan. The interest rate is determined by the plan administrator based on the current prime rate at the time of the loan and is fixed over the life of the note. A participant may have up to two general-purpose loans and one loan for a residence outstanding at any given time. (f) Administrative Expenses Certain administrative expenses of the Plan are paid by the Company. These costs include legal, accounting, and certain administrative fees. (3) Transactions with Parties-in-Interest At December 31, 2002 and 2001, the Plan held investments in funds sponsored by the Trustee with current values of $31,180,809 and $32,060,720, respectively. The Plan held investments in 254,578 and 282,798 shares of PEPCO Stock Fund with current values of $4,936,284 and $6,382,751 at December 31, 2002 and 2001, respectively. The Plan held investments in 103,219 and 150,629 shares of Southern Company with current values of $2,930,410 and $3,818,451 at December 31, 2002 and 2001, respectively. The Plan held 1,102,423 and 327,170 shares of Mirant Corporation common stock with current values of $2,061,532 and $5,241,274 at December 31, 2002 and 2001, respectively. These transactions qualify as party-in-interest transactions. (4) Investments Individual assets that represent 5% or more of the Plan's net assets available for benefits as of December 31, 2002 and 2001 are as follows: 2002 2001 -------------------- ------------------- T. Rowe Price Stable Value Fund $ 18,828,989 16,638,749 Mirant Corporation Stock Fund 2,061,532 5,241,274 T.

The Plan has been amended since receiving the determination letter. However, the Plan administrator believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. MIRANT SERVICES BARGAINING UNIT EMPLOYEE SAVINGS PLAN Notes to Financial Statements December 31, 2002 and 2001 (6) Key Provisions for Respective Collective Bargaining Units The following are key provisions of the Plan for each collective bargaining unit: Employee contribution Unions Eligibility Company match percentage ----------------- ------------------------------------------ ------------------------------------ ------------------------ Midwest Union Regular full-time and regular part-time Eligible after one year of service; 1% to 16% of base pay, members of the United Steelworkers 75% of the first 6% of participant's on a before-tax and/or of America Local #12502 base pay contributed to the Plan after-tax basis California Union Regular full-time and regular part-time Company match is based on years 1% to 15% of base pay, members of the International of service on a before-tax and/or Brotherhood of Electrical Workers after-tax basis Local #1245 Mid-Atlantic Union Regular full-time and regular part-time 40% of the first 6% of participant's 1% to 19% of base pay, members of the International base pay contributed to the Plan on a before-tax and/or Brotherhood of Electrical Workers after-tax basis Local #1900 New York Union Regular full-time and regular part-time Eligible after one year of service; 1% to 20% of base pay, members of the International 75% of the first 6% of participant's on a before-tax and/or Brotherhood of Electrical Workers base pay contributed to the Plan after-tax basis Local #503, upon completion of one year of service New England Union Regular full-time and regular part-time Eligible after one year of service; 1% to 30% of base pay, members of Utility Workers' Union of 100% of the first 4% of participant's on a before-tax and/or America Local #369 and #480 base pay contributed to the Plan after-tax basis (7) Plan Termination While it is the Company's intention to continue the Plan indefinitely, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA and the Plan agreement. In the event of Plan termination, participants will become 100% vested in their accounts. (8) Transfer to Affiliated Plan During 2002, due to changes in employment status, the Plan transferred account balances of certain participants to the Mirant Services Employee Savings Plan. (9) Transfer to Other Plan Effective June 5, 2002, following the sale of Stateline Power generating facility, plan assets of $159,605 attributable to Stateline Plant's employees were transferred to the Dominion Salaried Savings Plan. (10) Litigation On April 17, 2003, a purported class action lawsuit alleging violations of ERISA was filed in the United States District Court for the Northern District of Georgia entitled James Brown v. Mirant Corporation, et al., Civil Action No. 1:03-CV-1027 (the ERISA Litigation). The ERISA Litigation names as defendants Mirant Corporation, certain of its current and former officers and directors, and Southern Company. The plaintiff, who seeks to represent a putative class of participants and beneficiaries of the plan alleges that defendants breached their duties under ERISA by, among other things: (1) concealing information from the Plans' participants and beneficiaries; (2) failing to ensure that the Plans' assets were invested prudently; (3) failing to monitor the Plans' fiduciaries; and (4) failing to engage independent fiduciaries to make judgments about the Plans' investments. The plaintiff seeks unspecified damages, injunctive relief, attorneys' fees and costs. On June 3, 2003, a second purported class action lawsuit alleging violations of ERISA was filed in the United States District Court for the Northern District of Georgia entitled Greg Waller v. Mirant Corporation, et al., Civil Action No. 1:03-CV-1558 (the ERISA Litigation II). The ERISA Litigation II names as defendants Mirant Corporation, certain of its current and former officers and directors, and Southern Company. The claims asserted, factual allegations made, and the relief sought underlying this lawsuit are substantially similar to those described above in the ERISA Litigation.

Pursuant to the requirements of the Securities Exchange Act of 1934, the trustees (or other persons who administer the employee benefit plan) have duly caused this annual report to be signed by the undersigned thereunto duly authorized. MIRANT SERVICES BARGAINING UNIT EMPLOYEE SAVINGS PLAN /s/ Vance Booker Vance Booker Senior Vice President Administration and Technical June 26, 2003 EXHIBIT 23.1 INDEPENDENT AUDITORS' CONSENT The Board of Directors Mirant Corporation: We consent to the incorporation by reference in registration statement (No. 333-56574) on Form S-8 of our report dated June 20, 2003, relating to the statement of net assets available for plan benefits of the Mirant Services Bargaining Unit Employee Savings Plan as of December 31, 2002 and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2002 and related supplemental schedule, which report appears in the December 31, 2002 annual report on Form 11-K of the Mirant Services Bargaining Unit Employee Savings Plan. /s/KPMG LLP Atlanta, Georgia June 25, 2003 EXHIBIT 23.2 NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP Section 11(a) of the Securities Act of 1933, as amended (the "Securities Act"), provides that if any part of a registration statement at the time such part becomes effective contains an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, any person acquiring a security pursuant to such registration statement (unless it is proved that at the time of such acquisition such person knew of such untruth or omission) may sue, among others, every accountant who has consented to be named as having prepared or certified any part of the registration statement, or as having prepared or certified any report or valuation which is used in connection with the registration statement, with respect to the statement in such registration statement, report or valuation which purports to have been prepared or certified by the accountant. This Form 11-K is incorporated by reference into the following previously filed registration statements of Mirant Services Bargaining Unit Employee Savings Plan (the Plan): Registration Statement on Form S-8 file number 333-56574 (the "Registration Statement") and, for purposes of determining liability under the Securities Act, is deemed to be a new registration statement for each Registration Statement into which it is incorporated by reference. On May 15, 2002, the Plan dismissed Arthur Andersen LLP ("Arthur Andersen") as its independent public accountant and appointed KPMG LLP to replace Arthur Andersen. Both the engagement partner and the manager for the Plan's prior fiscal year audit are no longer with Arthur Andersen. As a result, the Plan has been unable to obtain Arthur Andersen's written consent to incorporate by reference into the Registration Statements Arthur Andersen's audit report regarding the Plan's financial statements as of December 31, 2001. Under these circumstances, Rule 437a under the Securities Act and Rule 2-02 of Regulation S-X promulgated by the Securities and Exchange Commission permit the Plan to file this Form 11-K without a written consent from Arthur Andersen. As a result, however, Arthur Andersen will have no liability under Section 11(a) of the Securities Act for any untrue statements of a material fact contained in the financial statements audited by Arthur Andersen or any omissions of a material fact required to be stated therein. Accordingly, you would be unable to assert a claim against Arthur Andersen under Section 11(a) of the Securities Act for any purchases of securities under the Registration Statements made on or after the date of the Form 11-K. However, to the extent provided in Section 11(b)(3)(C) of the Securities Act, other persons who are liable under Section 11(a) of the Securities Act, including the Plan's officers and directors, may still rely on Arthur Andersen's original audit reports as being made by an expert for purposes of establishing a due diligence defense under Section 11(b) of the Securities Act.
