The Administrative Committee shall be authorized to rescind the eligibility of any Participant if necessary to ensure that the Plan is maintained primarily for the purpose of providing deferred compensation to a select group of management or highly compensated employees under the Employee Retirement Income Security Act of 1974, as amended. ARTICLE V - BENEFITS 5.1 SERP Benefit. (a) Subject to Article XV of the Pension Plan, a Participant shall be entitled to a monthly SERP Benefit equal to: (1) 1.70% of the Participant's Average Monthly Earnings multiplied by his years (and fraction of a year) of Accredited Service to his Retirement Date, death or other termination of service, including a Social Security Offset, as adjusted, if necessary, under the terms of the Pension Plan for commencement prior to the Participant's Normal Retirement Date; less (2) such Participant's Retirement Income that is payable under the Pension Plan; less (3) such Participant's Supplemental Pension Benefit. (b) For purposes of Section 5.1(a)(1), the Participant's Average Monthly Earnings shall be calculated based on the Participant's Earnings that are considered under the Pension Plan in calculating his Retirement Income, but without regard to the limitation of Section 401(a)(17) of the Code, and including the following additional amounts: (1) any portion of such Participant's base pay that he may have elected to defer under The Southern Company Deferred Compensation Plan, but excluding Incentive Pay he deferred under such plan; and (2) any Incentive Pay which was earned as of the applicable Plan Year in excess of 25% of the Participant's corresponding base pay for the applicable Plan Year determined under this Section 5.1(b). In addition, to determine the Plan Years which produce the highest monthly average to calculate Average Monthly Earnings under the Plan, a Participant's Earnings should include those additional amounts provided for in Section 5.1(b). (c) For purposes of Section 5.1(a)(1), the Participant's years of Accredited Service shall include any deemed Accredited Service provided under the terms of any agreement concerning supplemental pension payments between the Participant and an Affiliated Employer. (d) To the extent that a Participant's Retirement Income under the Pension Plan is recalculated as a result of an amendment to the Pension Plan in order to increase the amount of his Retirement Income, the Participant's SERP Benefit shall also be recalculated in order to properly reflect such increase in determining payments of the Participant's SERP Benefit made on or after the effective date of such increase. 5.2 Distribution of Benefits. A Participant's SERP Benefit, as determined in accordance with Section 5.1, shall be payable in monthly increments on the first day of the month concurrently with and in the same manner as the Participant's Retirement Income under the Pension Plan. The Beneficiary of a Participant's SERP Benefit shall be the same as the beneficiary of the Participant's Retirement Income under the Pension Plan. 5.3 Allocation of SERP Benefit Liability. In the event that a Participant eligible to receive a SERP Benefit has been employed at more than one Affiliated Employer, the SERP Benefit liability shall be apportioned so that each such Affiliated Employer is obligated in accordance with Section 5.4 to cover the percentage of the total SERP Benefit as determined below. Each Affiliated Employer's share of the SERP Benefit liability shall be calculated by multiplying the SERP Benefit by a fraction where the numerator of such fraction is the pay, as defined by the Administrative Committee, received by the Participant at the respective Affiliated Employer multiplied by the Accredited Service earned by the Participant at the respective Affiliated Employer and where the denominator of such fraction is the sum of all numerators calculated for each respective Affiliated Employer for which the Participant has been employed. In the event that a Participant receives additional Accredited Service in accordance with Section 5.1(c), for purposes of determining liability under this Section 5.3, such Accredited Service shall be allocated to each Affiliated Employer which has contracted with the Participant in accordance with such contract and this allocation will be utilized to adjust the appropriate components of the fraction in the preceding sentence in determining each Affiliated Employer's share of the SERP benefit liability. 5.4 Funding of Benefits. The Company shall not reserve or otherwise set aside funds for the payment of its obligations under the Plan, and such obligations shall be paid solely from the general assets of the Company. 5.5 Withholding. There shall be deducted from the payment of any SERP Benefit due under the Plan the amount of any tax required by any governmental authority to be withheld and paid over by the Company to such governmental authority for the account of the Participant or Beneficiary entitled to such payment. ARTICLE VI - MISCELLANEOUS 6.1 Assignment. Neither the Participant, his Beneficiary nor his legal representative shall have any rights to sell, assign, transfer or otherwise convey the right to receive the payment of any SERP Benefit due hereunder, which payment and the right thereto are expressly declared to be nonassignable and nontransferable. Any attempt to assign or transfer the right to payment under the Plan shall be null and void and of no effect. 6.2 Amendment and Termination. The Plan may be amended or terminated at any time by the Board of Directors, provided that no amendment or termination shall cause a forfeiture or reduction in any benefits accrued as of the date of such amendment or termination. 6.3 No Guarantee of Employment. Participation hereunder shall not be construed as creating any contract of employment between an Affiliated Employer and a Participant, nor shall it limit the right of an Affiliated Employer to suspend, terminate, alter or modify, whether or not for cause, the employment relationship between the Affiliated Employer and a Participant. 6.4 Construction. This Plan shall be construed in accordance with and governed by the laws of the State of Georgia, to the extent such laws are not otherwise superseded by the laws of the United States.
