REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Plan Administrator of the
Southern Energy Resources, Inc.
Bargaining Unit Savings Plan:


We have audited the accompanying statement of net assets available for plan
benefits of the Southern Energy Resources, Inc. Bargaining Unit Savings Plan as
of December 31, 2000 and 1999 and the related statement of changes in net assets
available for plan benefits for the year ended December 31, 2000. These
financial statements and the schedule referred to below are the responsibility
of the Plan's administrator. Our responsibility is to express an opinion on
these financial statements and the schedule 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 plan benefits of the
Southern Energy Resources, Inc. Bargaining Unit Savings Plan as of December 31,
2000 and 1999 and the changes in its net assets available for plan benefits for
the year ended 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 supplemental schedule of assets (held
at end of year) is presented for purposes of additional analysis and is not a
required part of the basic financial statements but is 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
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

1.     PLAN DESCRIPTION

The following description of the Southern Energy Resources, Inc. Bargaining Unit
Savings Plan (the "Plan") provides only general information. Participants should
refer to the plan document for a more complete description of the Plan's
provisions.

General

The Plan is a defined contribution plan sponsored by Southern Energy Resources,
Inc. (the "Company") covering substantially all members of the Steelworkers of
America, AFL-CIO-CLC Local No. 12502 (the "Southern Energy Stateline Bargaining
Unit"). The Plan was amended to permit employees of the Company who are members
of the Utility Workers' Union of America Local No. 392 and 480, previously
employed by Commonwealth Electric Company ("Southern Energy New England
Bargaining Unit"), and members of the International Brotherhood of Electrical
Workers Local No. 503, previously employed by Orange and Rockland Utilities,
Inc. ("Southern Energy New York Bargaining Unit"), to participate in the Plan
effective January 1, 1999 and July 1, 1999, respectively.

The Plan was established to encourage employee savings, supplement retirement
and death benefits, and create a competitive compensation program for employees.
The Company appointed Merrill Lynch Trust Company (the "Trustee") as trustee to
execute investment transactions for the Plan. The Company serves as plan
administrator. The Plan is subject to the applicable provisions of the Employee
Retirement Income Security Act of 1974 ("ERISA"), as amended.

The Plan has distinct characteristics for the various bargaining units noted
above relative to eligibility and contributions.

Southern Energy Stateline Bargaining Unit

All employees of the Company who are members of the Southern Energy Stateline
Bargaining Unit are eligible to participate in the Plan upon completion of one
year of service, as defined by the Plan. Participants may enroll in the Plan on
the first day of any month after their completion of eligibility requirements.
Participants may elect to contribute, on a pretax or an after-tax basis, in 1%
increments up to 16% of their compensation, subject to certain limitations
defined by the Plan, into any investment fund offered by the Plan. Participants
may change their contribution percentages at any time. The Company provides a
matching contribution equal to 75% of the participant's contribution up to a
maximum of 6% of the participant's base compensation. The Company's matching
contribution is invested solely in Southern Company common stock. Effective
January 1, 2000, participants may elect to direct all or a portion of their
company matching contributions to any investment fund offered by the Plan once
these contributions have been credited to their accounts.

Southern Energy New England Bargaining Unit

An employee who is a member of the Southern Energy New England Bargaining Unit
and an eligible employee of the Company and has completed one hour of service,


                                       7


as defined by the Plan, is eligible to participate in the Plan. A temporary
employee, as defined by the Plan, is eligible to participate in the Plan after
completion of a consecutive 12-month period of employment with the Company.

Participants may elect to contribute, on a pretax or an after-tax basis, in 1%
increments up to 16% of their compensation, subject to certain limitations
defined by the Plan, into any investment fund offered by the Plan. Participants
may change their contribution percentages at any time. The Company provides a
matching contribution equal to 100% of the participant's contribution up to a
maximum of 4% of the participant's base compensation after one year of service.
The Company's matching contribution is invested solely in Southern Company
common stock. Effective January 1, 2000, participants may elect to direct all or
a portion of their company matching contributions to any investment fund offered
by the Plan once these contributions have been credited to their account.

Southern Energy New York Bargaining Unit

An employee who is a member of the Southern Energy New York Bargaining Unit, is
an eligible employee of Southern Energy New York, G.P., Inc., and has completed
one year of service with the Company is eligible to participate in the Plan. All
acquisition employees, as defined by the Plan, who participated in the Orange
and Rockland, Inc. Hourly Group Savings Plan ("O&R Plan") on June 30, 1999 were
eligible to participate in the Plan effective July 1, 1999.

Participants may elect to contribute, on a pretax or an after-tax basis, in 1%
increments up to 20% of their compensation, subject to certain limitations
defined by the Plan, into any investment fund offered by the Plan. Participants
may change their contribution percentages at any time. The Company provides a
matching contribution equal to 50% of the participant's contribution up to a
maximum of 6% of the participant's base compensation. The Company's matching
contribution is invested solely in Southern Company common stock. Effective
January 1, 2000, participants may elect to direct all or a portion of their
company matching contributions to any investment fund offered by the Plan once
these contributions have been credited to their account.

Participants had the opportunity to transfer their account balances from the O&R
Plan to the Plan. These accounts were transferred into the Merrill Lynch
Retirement Preservation Trust and then were eligible to be invested according to
the participant's investment allocations, as directed under the Plan. Prior to
January 1, 2000, the portion of the transferred account attributable to company
matching contributions, as defined by the O&R Plan, were treated as employer
matching contributions under the Plan. Effective January 1, 2000, transferred
balances relative to company matching contributions, as defined by the O&R Plan,
will not be invested in company stock under the Plan but will be invested at the
participant's discretion.

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 their accounts.

Benefit Payments

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. A participant or beneficiary may elect to have shares of
company stock distributed in common stock. 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.



                                       8

Participants may roll over a distribution from a qualified retirement plan of a
previous employer to the Plan. The rollover must occur within 18 months from the
date of the participant's employment with the Company.

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 plan benefits
and the changes therein. Actual results could differ from these estimates.

Administrative Expenses

All 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 Merrill Lynch Retirement Preservation Trust Fund is
fully benefit-responsive and is stated at contract value (which approximates
fair value) in accordance with SOP 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 statement of net assets available
for plan benefits.

Net Appreciation in Fair Value of Investments

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

4.     TAX STATUS

The Plan obtained a determination letter dated June 10, 1999 in which the
Internal Revenue Service stated that the Plan, as then designed, was in
compliance with the applicable requirements of the Internal Revenue Code (the
"Code"). The plan administrator believes that the Plan is currently designed and
is being operated in compliance with the applicable requirements of the 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.

6.     SUBSEQUENT EVENTS

On January 19, 2001, the Company announced, as part of its separation from
Southern Company, that the Company was changing its name from Southern Energy,
Inc. to Mirant Corporation. The Company began doing business as Mirant
Corporation on January 22, 2001 and legally changed its name on February 26,
2001.

                                       12


Effective April 2, 2001, the Plan merged with the Southern Energy Resources,
Inc. Savings Plan for Covered Employees into the Mirant Services Bargaining Unit
Employee Savings Plan (the "Mirant Plan"), which was established December 2000.
T. Rowe Price is the trustee of the Mirant Plan.
