REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Plan Administrator of the
Mirant Services Bargaining Unit
Employee Savings Plan:

We have audited the accompanying statements of net assets available for benefits
of the Mirant Services Bargaining Unit Employee Savings Plan as of December 31,
2001 and 2000 and the related statements of changes in net assets available for
benefits for the year ended December 31, 2001 and for the period from December
19, 2000 (inception) through December 31, 2000. These financial statements and
schedules are the responsibility of the Plan's administrator. Our responsibility
is to express an opinion on these financial statements and schedules based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
December 31, 2001 and 2000 and the changes in its net assets available for
benefits for the year ended December 31, 2001 and for the period from December
19, 2000 (inception) through December 31, 2000 in conformity with accounting
principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules of assets (held at end of
year) are presented for purposes of additional analysis and are not a required
part of the basic financial statements but are supplementary information
required by the Department of Labor Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. The
schedules have been subjected to the auditing procedures applied in the audits
of the basic financial statements and, in our opinion, are fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

                      Bargaining Unit Employee Savings Plan
                   Notes to Financial Statements and Schedules
                           December 31, 2001 and 2000



  1.     Plan Description

The following description of the Mirant Services Bargaining Unit Employee
Savings Plan (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.

General

The Plan is a stock bonus plan sponsored by Mirant Services, LLC (the "Company")
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.

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.

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.

Plan Administration

The Company appointed T. Rowe Price (the "Trustee") as trustee to execute
investment transactions and provide record-keeping services for the Plan. The
Company serves as plan administrator.

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 12 core investment funds offered by the Plan. Participants may

                                       4



change their contribution percentages at any time. The Plan has distinct
characteristics for the various bargaining units noted above relative to
eligibility and contributions (Note 6).

Profit-Sharing Arrangement

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. For the year ended December 31, 2001,
the discretionary contribution was $9,992. There were no discretionary
profit-sharing contributions from December 19, 2000 (inception) through December
31, 2000.

Participant Accounts and Vesting

Each participant's account is credited with his/her 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.

Benefits

Upon termination of service, death, or disability, a participant or his/her
beneficiary (upon the death of the participant) may elect to receive an amount
equal to the value of his/her 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/she 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.

Rollovers

Participants may roll over a distribution from a qualified retirement plan of a
previous employer to the Plan.

Investment Options

A participant may direct his/her contributions into any of the investment fund
options offered by the Plan. A participant may change his/her 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 and PEPCO
stock fund will have five years (until March 31, 2006) to liquidate the stock
and transfer it into other investment options within the Plan. These investments
are considered frozen; therefore, no new contributions may be made into this
option. There are no other restrictions on transferring in or out of any other
investments within the Plan.

Loans to Participants

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.

  2.     Summary of Significant Accounting Policies

Basis of Accounting

The accompanying financial statements have been prepared using the accrual
method of accounting.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires the Plan's management to use
estimates and assumptions that affect the net assets available for benefits and
the changes therein. Actual results could differ from these estimates.

Administrative Expenses

Record-keeping fees are paid by the Plan. All other administrative expenses are
paid by the Company.

Investment Valuation

Investments other than investment contracts are valued at quoted market prices.
Securities traded on a national securities exchange are valued at the last
reported sales price on the last business day of the year; investments traded in
the over-the-counter market and listed securities for which no sale was reported
on the last day of the plan year are valued at the last reported bid price. The
Plan's investment in the T. Rowe Price Stable Value Fund is fully
benefit-responsive and is stated at contract value (which approximates fair
value) in accordance with Statement of Position 94-4, "Reporting of Investment
Contracts Held by Health and Welfare Benefit Plans and Defined Contribution
Pension Plans."

Investment securities, in general, are exposed to various risks, including
credit, interest, and overall market volatility risks. Due to the level of risk
associated with certain investment securities, it is possible that changes in
values of investment securities will occur and that such changes could
materially affect the amount reported in the statements of net assets available
for benefits.

Net Appreciation (Depreciation) in Fair Value of Investments

Net realized gains (losses) and unrealized appreciation (depreciation) are
recorded in the accompanying statements of changes in net assets available for
benefits as net appreciation (depreciation) in fair value of investments.

Transfer to Affiliated Plan

During 2001, due to changes in employment status, the Plan transferred account
balances of certain participants to and from the Mirant Services Employee
Savings Plan.

Forfeitures

A participant will forfeit the value of his/her account if he/she separates from
service prior to becoming vested. Such forfeitures are utilized to reduce future
employer contributions. For the year ended December 31, 2001, $0 was used to
reduce employer contributions. As of December 31, 2001 and 2000, there were no
outstanding forfeiture accounts.

Related-Party Transactions

For the 2001 and 2000 plan years, certain plan investments are managed by T.
Rowe Price; therefore, these transactions qualify as party-in-interest
transactions.

  4.     Tax Status

The Company has applied for a determination letter with the Internal Revenue
Service. However, the plan administrator believes that the Plan is currently
designed and is being operated in compliance with the applicable requirements of
the Internal Revenue Code. Therefore, the plan administrator believes that the
Plan was qualified and the related trust was tax-exempt as of the financial
statement dates.


  5.     Plan Termination

Although it has not expressed any intent to do so, 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.

         Re:  Report of Independent Audit by Arthur Andersen

Ladies and Gentlemen:

In connection with the delivery of the report of independent  public accountants
relating to the audit of the statements of net assets  available for benefits of
the Mirant  Services  Bargaining  Unit Employee  Savings Plan (the "Plan") as of
December 31, 2001 and 2000, and the related  statements of changes in net assets
available  for benefits for the year ended  December 31, 2001 and for the period
from December 19, 2000 (inception)  through December 31, 2000 by Arthur Andersen
LLP ("Arthur Andersen") which has been included by Mirant Corporation ("Mirant")
in its  Annual  Report  for the Plan on Form  11-K  for the  fiscal  year  ended
December 31, 2001,  Arthur Andersen has represented to Mirant that the audit was
subject to Arthur  Andersen's  quality  control system for the US accounting and
auditing  practice  to provide  reasonable  assurance  that the  engagement  was
conducted in compliance with professional standards,  that there was appropriate
continuity of Arthur Andersen  personnel  working on the audit,  availability of
national  office   consultation,   and  availability  of  personnel  at  foreign
affiliates of Arthur Andersen to conduct the relevant portions of the audit.
