                     (a)  If  a  Participant  has Accredited  Service  with

          respect to the  Pension Plan of the Company, but not with respect

          amendment to such Pension Plan in order to increase the amount of

          his Retirement  Income, the Participant's  Pension Benefit  shall

          also be recalculated  in order to properly  reflect such increase

          in determining payments of the Participant's Pension Benefit made

          on or after the effective date of such increase.

          402(g), 415(c), and  415(e) of  the Code and  (2) to the ESOP  on

          behalf  of the Participant as a result of the limitations imposed

          by Sections 401(a)(17), 415(c), and 415(e) of the Code.

                     (b)  For purposes of this Section 5.2, the Non Pension

          Benefit of  a  Participant  shall  be  calculated  based  on  the

          Participant's Compensation  that  would have  been considered  in

          calculating allocations  to his  accounts under the  Savings Plan

          and ESOP, without regard to the limitations of Section 401(a)(17)

          or Section 402(g) of the Code,  but excluding any portion of  his

          Compensation  he may  have elected  to defer  under  the Deferred

          Compensation Plan.

                     (c)  All  amounts so  credited to  the Account  of the

          Participant shall be deemed to be invested in the Common Stock at

          the same  time that such  amounts would have been  so invested if

          they had been contributed by  the Company to the Savings  Plan or

          the ESOP, as the case may be.  In addition, such Account shall be

          credited  with respect to shares of Common Stock allocated to the

          Participant's Account as follows:

                          (1)  In   the  case   of  cash   dividends,  such

               additional shares  as could be purchased  with the dividends

               which would  have been  payable if  the credited shares  had

               been outstanding;

                          (2)  In the case of dividends payable in property

               other than cash or  Common Stock, such additional  shares as

               could be  purchased  with  the  fair  market  value  of  the

               property  which  would have  been  payable  if the  credited

               shares had been outstanding; or

                          (3)  In the case  of dividends payable  in Common

               Stock, such additional shares as would have been  payable on

               the credited shares if they had been outstanding.

                     (d)  As soon as practicable following the first day of

          his eligibility  to  have benefits  credited  to his  Account,  a

          Participant shall designate in writing on a form to be prescribed

          by the  Company the method of payment of his Account, which shall

          be the  payment  of a  single  lump sum  or  a series  of  annual

          installments  not  to   exceed  twenty  (20).     The  method  of

          distribution initially  designated by a Participant  shall not be

          revoked  and  shall  govern  the  distribution  of  each  Account

          established for  the benefit of  the Participant by  the Company.

          Notwithstanding, in the sole discretion of the Board of Directors

          upon application  by the Participant, the  method of distribution

          designated by such Participant  may be modified not prior  to 395

          days nor  later than 365  days prior  to a Participant's  date of

          separation  from  service   in  order  to  change  the   form  of

          distribution of his Account  in accordance with the terms  of the

          Plan.      Each   Participant,   his   Beneficiary,   and   legal

          representative  shall be bound as to any action taken pursuant to

          the method of distribution elected by a Participant and the terms

          of the Plan.

               5.3   Distribution of Benefits.

                     (a)  The Pension 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 Pension Benefit  shall be the

          same as  the beneficiary  of the Participant's  Retirement Income

          under the Pension Plan.

                     (b)  When a Participant terminates his employment with

          the Company, said  Participant shall be  entitled to receive  the

          market  value  of  any  shares  of  Common Stock  (and  fractions

          thereof) reflected in any  Account maintained by the Company  for

          his benefit under  the Plan in a single lump  sum distribution or

          annual installments not to exceed twenty (20).  Such distribution

          shall be  made not later than sixty (60) days following the close

          of the calendar  quarter in which  his termination of  employment

          occurs, or  as soon  as reasonably  practicable thereafter.   The

          transfer  by  a Participant  between  companies  in the  Southern

          electric  system shall  not  be deemed  to  be a  termination  of

          employment with  the  Company.   No  portion of  a  Participant's

          Account shall be distributed in Common Stock.





                                         -13-







          





                     (c)  In the event a  Participant elects to receive the

          distribution  of his  Account in  annual installments,  the first

          payment  shall be made not  later than sixty  (60) days following

          the close of  the calendar  quarter in which  his termination  of

          employment  occurs,   or  as   soon  as   reasonably  practicable

          thereafter, and shall  be an amount  equal to the balance  in the

          Participant's Account divided by the number of annual installment

          payments.   Each  subsequent annual  payment shall  be an  amount

          equal  to the balance in the Participant's Account divided by the

          number  of the remaining annual payments and  shall be due on the

          anniversary  of  the preceding  payment date.    No portion  of a

          Participant's Account shall be distributed in Common Stock.

                     (d)  Upon  the death  of  a Participant,  or a  former

          Participant  prior to the payment of all amounts credited to said

          Participant's Account,  the unpaid balance  shall be paid  in the

          sole discretion  of the Board of  Directors (1) in a lump  sum to

          the designated Beneficiary of a Participant or former Participant

          within sixty  (60)  days  following  the close  of  the  calendar

          quarter in which the  Board of Directors is provided  evidence of

          the  Participant's death  (or as  soon as  reasonably practicable

          thereafter)  or  (2) in accordance  with the  distribution method

          chosen  by   such  Participant   or  former  Participant.     The



                                         -14-







          





          Beneficiary  designation may  be  changed by  the Participant  or

          former Participant at any  time without the consent of  the prior

          Beneficiary.   In the event  a Beneficiary designation  is not on

          file  or  the designated  Beneficiary  is deceased  or  cannot be

          located, payment will be made to the estate of the Participant or

          former Participant.  No portion  of a Participant's Account shall

          be distributed in Common Stock.

                     (e)  Upon the  total  disability of  a Participant  or

          former  Participant,   as  determined  by   the  Social  Security

          Administration,  the unpaid balance of  his Account shall be paid

          in  the sole discretion  of the Board of  Directors (1) in a lump

          sum  to  the  Participant or  former  Participant,  or  his legal

          representative within sixty (60)  days following the notification

          of the Board of  Directors of the determination of  disability by

          the  Social Security  Administration  (or as  soon as  reasonably

          practicable   thereafter)   or   (2) in   accordance   with   the

          distribution   method  elected  by  such  Participant  or  former

          Participant.   No  portion  of a  Participant's Account  shall be

          distributed in Common Stock.

                     (f)  The  Board of  Directors in  its sole  discretion

          upon   application   made  by   the  Participant,   a  designated

          Beneficiary, or  their  legal representative,  may  determine  to



                                         -15-







          





          accelerate payments or, in the event of death or total disability

          (as determined  by Social Security Administration),  to extend or

          otherwise  make payments in a manner different from the manner in

          which such payment would be made under the method of distribution

          elected by the Participant in the absence of such determination.

               5.4   Funding  of  Benefits.   The  Company  maintaining  an

          Account for the  benefit of  a Participant 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.    Notwithstanding  that  a

          Participant shall  be  entitled to  receive  the balance  of  his

          Account under the Plan,  the assets from which such  amount shall

          be  paid  at all  times  remain  subject  to  the claims  of  the

          creditors of the Company.

               5.5   Withholding.  There shall be deducted from the payment

          of any Pension Benefit or Non  Pension 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,

          or  his  legal  representative shall  have  any  rights  to sell,

          assign, transfer or  otherwise convey  the right  to receive  the

          payment of  any  Pension  Benefit  or  Non  Pension  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 the Company  and a  Participant, nor shall  it limit  the

          right  of  the  Company  to suspend,  terminate,  alter,  modify,

          whether or not for cause, the employment relationship between the

          Company and a Participant.

          by the laws of the United States.
