BARGAINING UNIT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS APRIL 30, 2001 AND DECEMBER 31, 2000 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. On January 19, 2001, the Company announced, as part of its separation from Southern Company, that the Company was changing its name to Mirant Corporation. The Company began doing business as Mirant Corporation on January 22, 2001 and legally changed its name on February 26, 2001. On May 1, 2001, the Plan's assets merged along 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 originally established on December 19, 2000. The Company appointed T. Rowe Price as trustee of the Mirant Plan. 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 7 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 option 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. Effective January 1, 2000, participants may elect to direct all or a portion of their company matching contributions to any investment option 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, 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 option 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. Effective January 1, 2000, participants may elect to direct all or a portion of their company matching contributions to any investment option 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 option 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. Effective January 1, 2000, participants may elect to direct all or a portion of their company matching contributions to any investment option 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, was 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 direction. 8 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. Rollovers 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.

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 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 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 Depreciation 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 benefits as net depreciation in fair value of investments. 3. INVESTMENTS Individual assets that represent 5% or more of the Plan's net assets available for benefits as of December 31, 2000 are as follows: Merrill Lynch Retirement Preservation Trust $2,731,135 Massachusetts Investors Trust 946,129 Davis New York Venture Fund 951,413 Southern Company Common Stock 2,501,360 Merrill Lynch Equity Index Trust 947,945 Franklin Small-Cap Growth Fund 1,204,424 12 The Plan's investments (including gains and losses on investments bought and sold as well as held during the year) appreciated (depreciated) as follows for the four-month period ended April 30, 2001: Investments, at fair value: Mutual funds $(367,449) Common stock (469,665) Common/collective trust (66,402) ---------- $(903,516) ========== 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 has been amended since receiving the determination letter; however, 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. 13 SIGNATURE 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 report to be signed by the undersigned thereunto duly authorized.
