Any installment of interest on the bonds of this Supplemental Indenture may, at the Company’s option, be paid by mailing checks for such interest payable to or upon the written order of the person entitled thereto to the address of such person as it appears on the registration books.  The bonds of this Supplemental Indenture shall be registrable, transferable and exchangeable in the manner provided in Sections 4.08 and 4.09 of the Indenture, at either of such offices or agencies.
Section 4.    The bonds of this Supplemental Indenture, upon the mailing of notice and in the manner provided in Section 7.01 of the Indenture (except that no published notice shall be required for the bonds of this Supplemental Indenture) and with the effect provided in Section 7.02 thereof, shall be redeemable at the option of the Company, as a whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the bonds of this Supplemental Indenture to be redeemed plus accrued and unpaid interest of the principal amount being redeemed to the date of redemption plus the Make-Whole Amount applicable thereto.  “Make-Whole Amount” means, with respect to any bond of this Supplemental Indenture, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such bond of this Supplemental Indenture over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero.  For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:
“Called Principal” means, with respect to any bond of this Supplemental Indenture, the principal of such bond of this Supplemental Indenture that is to be redeemed.
“Discounted Value” means, with respect to the Called Principal of any bond of this Supplemental Indenture, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the bond of this Supplemental Indenture is payable) equal to the Reinvestment Yield with respect to such Called Principal.

- 24 -

“Reinvestment Yield” means, with respect to the Called Principal of any bond of this Supplemental Indenture, the sum of (x) 0.50% plus (y) the yield to maturity implied by the “Ask Yield(s)” reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.  If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the “Ask Yields” Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life.  The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable bond.
If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any bond of this Supplemental Indenture, the sum of (x) 0.50% plus (y) the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date.  If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life.  The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable bond.
“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (a) such Called Principal into (b) the sum of the products obtained by multiplying (1) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (2) the number of years, computed on the basis of a 360-day year comprised of twelve 30-day months and calculated to the nearest two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.
“Remaining Scheduled Payments” means, with respect to the Called Principal of any bond of this Supplemental Indenture, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due 

- 25 -

date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the bond of this Supplemental Indenture, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to the terms of this Supplemental Indenture.
“Settlement Date” means, with respect to the Called Principal of any bond of this Supplemental Indenture, the date on which such Called Principal is to be redeemed.
Section 5.    No sinking fund is to be provided for the bonds of this Supplemental Indenture.

SOUTHERN COMPANY 
DEFERRED COMPENSATION PLAN
ARTICLE I
Purpose and Adoption of Plan
1.1    Adoption:  Southern Company Services, Inc. and the other Employing Companies established the Deferred Compensation Plan for The Southern Electric System effective October 1, 1988. The Plan has been amended from time to time including the good faith amendment and restatement effective January 1, 2005 and then again effective January 1, 2009, both of which were adopted to comply with Code Section 409A, including the proposed, temporary, or final regulations, or other guidance issued by the Secretary of Treasury and the Internal Revenue Service with respect thereto (collectively “409A Guidance”).  This amendment and restatement effective January 1, 2018 was adopted to add Deemed Investment Options which align with the investment options offered under the Company’s qualified defined contribution plan, to provide that an employee of a Southern Company Gas affiliated company who had an account under the AGL Resources Inc. Nonqualified Savings Plan on December 31, 2017 is eligible to participate in the Plan effective January 1, 2018, and to make other design changes, as authorized by the Company.  Except as otherwise provided herein and consistent with Section 1.3, the terms of the Plan as in effect prior to January 1, 2005 shall continue to be applicable to deferrals made pursuant to the Plan prior to such January 1, 2005. 
1.2    Purpose:  This Southern Company Deferred Compensation Plan is designed to permit a select group of management or highly compensated employees (“Top-Hat Employees”) within the meaning of Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) to elect to defer a portion of their regular compensation during each payroll period and to defer all or a portion of certain short-term incentive payments until a specified date 

or until their death, retirement, or other Separation from Service with an Employing Company. Effective January 1, 2010, the Plan was also designed to accept matching contributions made by employing companies based on a set percentage multiplied by the Compensation deferred by a Participant into the Plan. The Plan is intended to constitute a non-qualified deferred compensation plan that complies with the provisions of Code Section 409A and an unfunded deferred compensation arrangement for Top-Hat Employees governed by ERISA whose benefits shall be paid solely from the general assets of the Employing Companies.
1.3    Schedule of Provisions for Pre-2005 Deferrals:  The attached Schedule sets forth the operative provisions of the Plan applicable to “grandfathered” deferrals of Compensation and Incentive Pay made by Participants which are treated by the Employing Companies as not subject to Section 409A of the Code.  The Account balance (plus earnings thereon) of the grandfathered deferrals shall only be subject to the provisions set forth in the Schedule.  In accordance with transition rules under the 409A Guidance, these provisions are only intended to preserve the rights and features of the “grandfathered” deferrals and are, therefore, not intended to “materially modify” any aspect of such rights and features.  Provisions of the Schedule should be so construed whenever necessary or appropriate.  Provisions in the Schedule shall only be amended in accordance with the Schedule’s terms.
1.4    409A Transition Elections:  At a time and in a manner determined by the Committee, Participants shall make timely elections to conform to the Plan’s terms effective on and after January 1, 2005.  Where a Participant fails to make such elections required by the Committee, with regard to the form of distribution (i.e., lump sum or installment), the Committee shall establish a default distribution form based on the following hierarchy:  first, the most current distribution form in effect applicable to the Account balance governed by the Schedule of 

2

Provisions for Pre-2005 Deferrals; if none, lump sum.  Such elections are intended to meet the transition requirements of Section 409A of the Code and Internal Revenue Service Notice 2005‐1.

Administration of Plan
3.1    Effective May 31, 2007, the general administration of the Plan shall be placed in the “Committee” which shall consist of the Benefits Administration Committee, the members of which shall be appointed from time to time by the Fiduciary Oversight Committee of the Board of Directors.

The Committee shall interpret the Plan and shall determine all questions arising in the administration, interpretation, and application of the Plan. Any such 

8

determination by the Committee shall be conclusive and binding on all persons. The Committee shall be the Plan’s agent for service of process.
(b)    If a claim for benefits under the Plan is denied, in whole or in part, the Committee will provide a written notice of the denial within a reasonable period of time, but not later than 90 days after the claim is received.  If special circumstances require more time to process the claim, the Committee will issue a written explanation of the special circumstances prior to the end of the 90 day period and a decision will be made as soon as possible, but not later than 180 days after the claim is received.
The written notice of claim denial will include:
		
	•
	Specific reasons why the claim was denied;

		
	•
	Specific references to applicable provisions of the Plan document or other relevant records or papers on which the denial is based, and information about where a Participant or his or her beneficiary may see them;

		
	•
	A description of any additional material or information needed to process the claim, and an explanation of why such material or information is necessary;

		
	•
	An explanation of the claims review procedure, including the time limits applicable to such procedure, as well as a statement notifying the Participant or his or her beneficiary of their right to file suit if the claim for benefits is denied, in whole or in part, on review.

Upon request, a Participant or his or her beneficiary will be provided without charge, reasonable access to, and copies of, all non-confidential documents that are relevant to any denial of benefits.  A claimant has 60 days from the day he or she receives the original denial to request 

9

a review.  Such request must be made in writing and sent to the Committee.  The request should state the reasons why the claim should be reviewed and may also include evidence or documentation to support the claimant’s position.
The Committee will reconsider the claimant’s claim, taking into account all evidence, documentation, and other information related to the claim and submitted on the claimant’s behalf, regardless of whether such information was submitted or considered in the initial denial of the claim.  The Committee will make a decision within 60 days.  If special circumstances require more time for this process, the claimant will receive written explanation of the special circumstances prior to the end of the initial 60 day period and a decision will be sent as soon as possible, but not later than 120 days after the Committee receives the request.
No legal action to recover benefits or enforce or clarify rights under a Plan can be commenced until the Participant or his or her beneficiary has first exhausted the claims and review procedures provided under the Plan.
3.4    The Committee may adopt such regulations as it deems desirable for the conduct of its affairs and may appoint such accountants, counsel, actuaries, specialists, and other persons as it deems necessary or desirable in connection with the administration of this Plan.
3.5    The Committee shall be reimbursed by the Employing Companies for all reasonable expenses incurred by it in the fulfillment of its duties, including, but not limited to, fees of accountants, counsel, actuaries, and other specialists, and other costs of administering the Plan.
3.6    (a)    The Committee is responsible for the daily administration of the Plan and may appoint other persons or entities to perform any of its fiduciary functions. The Committee and any such appointee may employ advisors and other persons necessary or convenient to help 

10

the Committee carry out its duties, including its fiduciary duties. The Committee shall review the work and performance of each such appointee, and shall have the right to remove any such appointee from his or her position. Any person, group of persons, or entity may serve in more than one fiduciary capacity.
(b)    The Committee shall maintain accurate and detailed records and accounts of Participants and of their rights under the Plan and of all receipts, disbursements, transfers, and other transactions concerning the Plan. Such accounts, books, and records relating thereto shall be open at all reasonable times to inspection and audit by the Board of Directors and by any persons designated thereby.
(c)    The Committee shall take all steps necessary to ensure that the Plan complies with the law at all times. These steps shall include such items as the preparation and filing of all documents and forms required by any governmental agency; maintaining of adequate Participants’ records; recording and transmission of all notices required to be given to Participants and their beneficiaries; the receipt and dissemination, if required, of all reports and information received from an Employing Company; securing of such fidelity bonds as may be required by law; and doing such other acts necessary for the proper administration of the Plan. The Committee shall keep a record of all of its proceedings and acts, and shall keep all such books of account, records, and other data as may be necessary for proper administration of the Plan. The Committee shall notify the Employing Companies upon their request of any action taken by the Committee, and when required, shall notify any other interested person or persons.

11

ARTICLE IV 
Eligibility
4.1    Any Employee who is determined eligible to participate in accordance with Section 2.28 or 4.2 of the Plan and whose base compensation and salary grade level equals or exceeds such minimum threshold as may be established by the Committee from time to time may elect to participate in the Plan beginning on any Enrollment Date by electing to have his or her Compensation and/or Incentive Pay reduced and such amounts contributed to the Plan in accordance with Article V hereof, and directing the investment of such contributions in accordance with Article VI hereof. An Employee who is eligible to participate and elects to defer Compensation and/or Incentive Pay shall be a Participant in the Plan.  The Committee shall be authorized to establish the minimum base compensation and the salary grade level required for eligibility to participate in the Plan, to be effective as of the first day of the next succeeding Plan Year. Notwithstanding the foregoing, any Employee eligible to participate in any similar group employee deferred compensation plan maintained by an Employing Company or maintained by a Non-adopting Company shall be ineligible to defer Compensation or Incentive Pay under this Plan, unless the Committee in its sole discretion shall determine otherwise.
4.2    The Committee shall determine which Employees are eligible to participate in the Plan.  Additionally, the Committee shall be authorized to modify the minimum base compensation and the salary grade threshold described in Section 4.1 of the Plan and to rescind the eligibility of any Participant to continue deferrals if this is necessary or advisable 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, as such terms are defined by the ERISA.  A Participant whose eligibility is rescinded or who loses eligibility for any reason shall 

12

not be eligible to defer Compensation or Incentive Pay until eligibility is restored in accordance with the guidelines established by the Committee.
4.3    The Committee shall have the authority to permit, if it deems appropriate, separate Deferral Elections under Article V hereof, Investment Elections under Article VI hereof, and Distribution Elections under Article VII hereof for Compensation and/or Incentive Pay, respectively. Employer Matching Contributions will be governed by Deferral Elections, Investment Elections, and Distribution Elections as contemplated in the preceding sentence in the same manner as Compensation. 
ARTICLE V
Deferral Election
5.1    (a) A Participant may elect to defer payment of a portion of his or her Compensation otherwise payable to him by his or her Employing Company during each payroll period of the next succeeding Plan Year by any whole percentage not to exceed fifty percent (50%) of his or her Compensation, or such greater or lesser amount as shall be determined by the Committee from time to time. A Participant may also elect to defer payment of up to one hundred percent (100%), by whole percentages, of any Incentive Pay otherwise payable to him or her by his or her Employing Company.
(b) With respect to a Participant who elects to defer payment of a portion of his or her Compensation in accordance with (a) above, an Employing Company shall match any such deferred amount at five and one-tenths percent (5.1%) at the time such Compensation is deferred in accordance with Article V. 
5.2    The Deferral Election shall be made in a manner prescribed by the Committee and shall state as follows:

13

(a)    That the Participant wishes to make an election to defer the receipt of a portion of his or her Compensation and/or all or a portion of his or her Incentive Pay;
(b)    The whole percentage of his or her Compensation and/or Incentive Pay which the Participant elects to defer; and
(c)    The Distribution Election under Article VII hereof.
5.3    The Deferral Election of a Participant shall be made by the Participant in a manner prescribed by the Committee and delivered by the date established by the Committee and shall be effective on the first day of the Plan Year immediately following the date of the Deferral Election. A Deferral Election with respect to the deferral of future Compensation and/or Incentive Pay shall be an annual election for each Plan Year; except that, with respect to certain Incentive Pay that is retention compensation, the deferral of such compensation may be set forth in writing in the retention arrangement at the time such arrangement is established.  The termination of a Participant’s participation in the Plan shall not affect the Participant’s Compensation (plus Employer Matching Contributions made thereon, if any) or Incentive Pay previously deferred under the Plan, which shall be invested and distributed in accordance with the Participant’s elections and the terms and conditions of the Plan.  Such terminated Participant shall become an inactive Participant with respect to eligibility to make future deferrals under this Plan.
5.4    The Committee may cancel the Deferral Election of a Participant who incurs a disability. Any cancellation under this section must occur by the later of the end of the calendar year in which the Participant incurs the disability or the 15th day of the third month after the date the Participant incurs the disability. For purposes of this section, “disability” shall have the meaning set forth in Treasury Regulation Section 1.409A-3(j)(4)(xii). 

14

ARTICLE VI

ARTICLE VII 
Account Distribution
7.1    (a)    When a Participant Separates from Service with an Employing Company or otherwise becomes entitled to commence the distribution of all or a portion of his or her Account, he or she shall be entitled to receive in cash an amount equal to the dollar amount of any deferrals, any Employer Matching Contributions, and any amounts in lieu of interest thereon credited to his or her Account under Section 6.2 hereof, and the dollar value of the product of the Closing Price multiplied by the number of deemed shares of Common Stock (and fractions thereof) credited to his or her Account in accordance Section 6.3 hereof, determined as of the date the Account is valued for distribution.  If such date is a non-business day, the Account shall be valued as of the next business day.  Such amounts shall be paid in accordance with the Participant’s Distribution Elections made in accordance with Section 7.4.  No portion of a Participant’s Account shall be distributed in Common Stock.
(b)    The transfer by a Participant between subsidiaries or affiliates of Southern shall not be deemed to be a termination of employment with an Employing Company for purposes of the Plan.
7.2    In the event that a Participant has made or is deemed to have made a Distribution Election to receive a lump sum distribution of his or her Account, the dollar amount determined under Section 7.1 hereof shall be paid to the Participant as soon as practicable but not later than seventy-five (75) days following the date on which the Participant’s Separation from Service occurs or such specified date, if any, elected by the Participant in accordance with Section 7.6.  Notwithstanding the foregoing, if a Participant is a Key Employee, such Participant shall be subject to the Key-Employee Delay and the payment of the lump sum following Separation 

18

from Service shall be as of the beginning of the seventh full calendar month.  Such delay shall not apply to a Participant’s election under Section 7.6.
7.3    In the event that a Participant has made a Distribution Election to receive the distribution of his or her Account in annual installments, the first payment shall be made as soon as practicable but not later than seventy-five (75) days following the date on which the Participant’s Separation from Service occurs and shall be in an amount equal to the dollar balance in the Participant’s Account determined under Section 7.1 hereof, divided by the number of annual installments elected. Subsequent annual installments shall be in an amount equal to the dollar value of the Participant’s Account determined under Section 7.1 hereof divided by the number of the remaining annual payments, and shall be paid as of each anniversary of the initial payment date (or what would have been the initial payment date but for the Key-Employee Delay) until the balance of the Participant’s Account is paid in full.  For purposes of Section 409A of the Code, installments shall be treated as a single payment.  Notwithstanding the foregoing, if a Participant is a Key Employee, such Participant shall be subject to the Key-Employee Delay and the first installment payment following Separation from Service shall be as of the beginning of the seventh full calendar month.  Upon the death of a Participant prior to the complete distribution of his or her Account in annual installments, the unpaid Account balance shall be paid in accordance with the Distribution Election made by such Participant to the Participant’s designated 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 Participant’s estate.
7.4    When a Participant makes a Deferral Election, he or she shall make a Distribution Election in a manner prescribed by the Committee.  Such Distribution Election shall apply only 

19

to the amounts attributable to that specified Deferral Election (including any Employer Matching Contribution made on a deferral of Compensation) and may not be subsequently revoked, except that one or more Distribution Elections may be modified by a Participant but only if such modification meets the requirements of a Modification Delay. Each year’s Deferral Election is allowed a one-time re-deferral in which the time and/or form of payment can be modified. In accordance with Section 409A of the Code, any changes to time and/or form of payment, must be made at least 12 months before the originally scheduled commencement date, and result in a delay of at least five years from the originally scheduled commencement date. If disability, death, or a Separation of Service occur within 12 months after the re-deferral election and cause the distribution to be made less than 12 months before the originally scheduled commencement date, the original Deferral Election shall apply and the re-deferral election shall be revoked.  
7.5    Upon the death of a Participant prior to Separation from Service, the Account balance shall be paid to the Participant’s designated beneficiary determined pursuant to Section 7.9 in the form of a lump sum as soon as practicable but not more than seventy-five (75) days following the date of the Participant’s death.
7.6    In addition to distributions commencing upon a Separation from Service, Participants may elect in a manner prescribed by the Committee to commence payment of all or a portion of his or her Deferral Election as of a specified date. Distributions that commence prior to Separation from Service must be paid in a lump sum.
7.7    Upon the Total Disability of a Participant, the balance of his or her Account shall be paid in accordance with Participant’s Deferral Election commencing as of such Participant’s Separation from Service and, if applicable, as of any date specified by the Participant pursuant to an election under Section 7.6.

20

7.8    Upon the occurrence of an Unforeseeable Emergency and an application made by a Participant or his or her beneficiary, the Committee may in its sole discretion determine to make a lump-sum payment up to the amount in the Participant’s Account in accordance with the requirements of Code Section 409A to satisfy such Unforeseeable Emergency.  Such lump-sum payment shall reduce pro rata the amount attributable to each annual Deferral Election made by the Participant.
7.9    Beneficiary designations may be made or changed by the Participants in a manner prescribed by the Committee at any time without the consent of any prior beneficiary.  In the event a beneficiary designation is not on file or the designated beneficiary is deceased or cannot be located following the death of the Participant, payment will be made to the Participant’s estate.
7.10    In the event a Participant who is employed on or after January 1, 1999 with an “Employing Company” (as defined in the Change in Control Benefits Protection Plan) disputes the calculation of his Account or payment of amounts due under the terms of the Plan, such Participant has recourse against the Company, the Employing Company by which Participant is employed, if different, the Plan, and the Trust for the payment of benefits to the extent the Trust so provides.
7.11    The provisions of the Change in Control Benefits Protection Plan are incorporated herein by reference to determine the occurrence of a change in control or preliminary change in control of Southern or an Employing Company, the benefits to be provided hereunder, and the funding of the Trust in the event of such a change in control.  Any modifications to the Change in Control Benefits Protection Plan are likewise incorporated herein and are otherwise intended to comply with 409A of the Code.

ARTICLE VIII 
Miscellaneous Provisions
8.1    Neither the Participant, his or her beneficiary, nor his or her legal representative shall have any rights to commute, sell, assign, transfer, or otherwise convey the right to receive any payments hereunder, which payments and the rights thereto are expressly declared to be non-assignable and nontransferable. Any attempt to assign or transfer the right to payments of this Plan shall be void and have no effect.
8.2    Except as expressly limited under the terms of the Trust, an Employing Company maintaining an Account for the benefit of a Participant shall neither reserve nor specifically set aside funds for the payment of its obligations under the Plan.  In any event, such obligations shall be paid or deemed to be paid solely from the general assets of the Employing Companies. Participants shall only have the status of a general, unsecured creditor of the Employing Company(ies).  Notwithstanding that a Participant shall be entitled to receive the balance of his or her Account under the Plan, the assets from which such amount may be paid shall at all times be subject to the claims of the creditors of the Participants’ Employing Companies.
8.3    Except for the provisions of Section 7.10 hereof, which may not be amended following a “Southern Change in Control” or “Subsidiary Change in Control” (as defined in the Change in Control Benefits Protection Plan), the Plan may be amended, modified, or terminated by the Board of Directors in its sole discretion at any time and from time to time; provided, however, that no such amendment, modification, or termination shall impair any rights to any amounts which have been earned or deferred under the Plan prior to such amendment, modification, or termination.  Effective March 1, 2006, the Plan may also be amended by the Committee (a) if such amendment does not involve a substantial increase in cost to any 

22

Employing Company, or (b) as may be necessary, proper, or desirable in order to comply with laws or regulations enacted or promulgated by any federal or state governmental authority.
8.4    It is expressly understood and agreed that the payments made in accordance with the Plan are in addition to any other benefits or compensation to which a Participant may be entitled or for which he or she may be eligible, whether funded or unfunded, by reason of his or her employment with any Employing Company.
8.5    There may be deducted from any payment under the Plan in accordance with the requirements of 409A of the Code the amount of any tax owed by the Participant required by any governmental authority to be withheld and paid over by an Employing Company to such governmental authority for the account of the person entitled to such distribution.  The Employing Company may also seek payment for tax owed by the Participant directly from such Participant or may withhold such tax from compensation otherwise paid to such Participant.
8.6    Any Compensation or Incentive Pay deferred by a Participant while employed by an Employing Company and any Transferred Amounts shall not be considered “compensation,” as the term is defined in the Employee Savings Plan, the Employee Stock Ownership Plan, or the Pension Plan unless any one or all of those plans expressly provides otherwise. Distributions from a Participant’s Account shall not be considered wages, salaries, or compensation under any other employee benefit plan.
8.7    No provision of this Plan shall be construed to affect in any manner the existing rights of an Employing Company to suspend, terminate, alter, modify, whether or not for cause, the employment relationship of the Participant and his or her Employing Company.
8.8    For the avoidance of doubt, the provisions of the Plan effective in the Plan’s amendment and restatement dated January 1, 2004 (“2004 Plan”) concerning Mirant Shares were 

23

applied through the liquidation of Mirant Shares as a form of investment in the Plan as of June 30, 2006.  Although these provisions concerning Mirant Shares are not restated in this amendment and restatement, a Participant’s rights concerning Mirant Shares are as set forth in such 2004 Plan.  To this limited extent, the provisions in the 2004 Plan concerning Mirant Shares are incorporated herein.
8.9    This Plan, and all rights under it, shall be governed by and construed in accordance with the laws of the State of Georgia without regard to conflict of laws principles to the extent not preempted by ERISA.

IN WITNESS WHEREOF, the amended and restated Plan has been executed by duly authorized officers of Southern Company Services, Inc. pursuant to resolutions of the Board of Directors and the Committee, this 12th day of December, 2017.
