ACUITY BRANDS, INC.
2005 SUPPLEMENTAL DEFERRED SAVINGS PLAN
(As Amended and Restated effective July 1, 2019)

ARTICLE I
INTRODUCTION AND ESTABLISHMENT
Effective as of November 30, 2001, Acuity Brands, Inc. ("Company") established the Acuity Brands, Inc. Supplemental Deferred Savings Plan ("Prior Plan") for the benefit of eligible management and highly compensated employees of the Company and its Subsidiaries and Business Units. The Plan was designed to assist and encourage eligible employees to accumulate capital and to supplement their retirement income.
Because the law applicable to nonqualified deferred compensation plans was significantly changed effective January 1, 2005, the Company decided to adopt a new deferred compensation plan, the 2005 Supplemental Deferred Savings Plan (the "Plan") for deferrals and Company contribution credits occurring on or after January 1, 2005, and for unvested amounts credited to participants under the Prior Plan as of December 31, 2004. The vested amounts credited to participants as of December 31, 2004 under the Prior Plan remain credited under the Prior Plan and subject to the terms and conditions of the Prior Plan.
The Plan has been amended several times since its adoption and this amendment and restatement is intended to incorporate said amendments into the Plan document. Accordingly, this amendment and restatement is hereby effective July 1, 2019.

2.1 "Account" means the records maintained by the Plan Administrator to determine the Participant’s deferrals and any Company contribution credits on the Participant’s behalf under this Plan. Such Account may be reflected as an entry in the Company’s (or Employer’s) records, or as a separate account under a trust, or as a combination of both. Each Participant’s Account may consist of the following subaccounts: a Deferral Subaccount to reflect his deferrals of Compensation; a Matching Subaccount for Employer matching contribution credits; a Supplemental Subaccount for any supplemental Employer contribution credits; and a Deferred Restricted Stock Subaccount to reflect any deferrals of Restricted Stock. The Plan Administrator may establish such additional subaccounts as it deems necessary for the proper administration of the Plan. Effective January 1, 2009, a Participant’s Matching Subaccount and Supplemental Subaccount shall for vesting purposes be referred to collectively as the Participant’s "Employer Contribution Account" and shall be divided into a Pre-2009 Employer Contribution Account for Employer contribution credits prior to January 1, 2009 and Post-2008 Employer Contribution Account for Employer contribution credits on or after January 1, 2009.

2.3 "Beneficiary" means the person or persons last designated in writing by the Participant under the Plan to receive the vested amount in his Account in the event of such Participant's death and, if no such designation has been made under this Plan, the designation of Beneficiary made by the Participant under the Prior Plan shall be deemed to be the designation under this Plan; if no such designation under either plan shall be in effect at the time of a Participant's death or if all designated Beneficiaries shall have predeceased the Participant, then the Beneficiary shall be the Participant's estate or his personal representative.

(d) A complete liquidation or dissolution of the Company or the sale or other disposition of all or substantially all of the assets of the Company.

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur pursuant to subsection (a) above, solely because twenty percent (20%) or more of the combined voting power of the Company’s then outstanding securities is acquired by (i) a trustee or other fiduciary holding securities under one or more employee benefit plans maintained by the Company or any of its subsidiaries, or (ii) any corporation which, immediately prior to such acquisition, is owned directly or indirectly by the stockholders of the Company in the same proportion as their ownership of stock in the Company immediately prior to such acquisition.

ARTICLE III
PARTICIPATION; DEFERRAL ELECTION
3.1 Eligibility to Participate. Prior to, or at the beginning of, each Plan Year, the Company (or its designee) shall specify the Executives who are eligible to make deferral elections under the Plan for the following Plan Year and to receive Matching Subaccount and Supplemental Subaccount credits (an "Eligible Executive"). Such eligibility designation may be

made by establishing a minimum compensation level for participation or by the use of such other criteria as the Company (or its designee) deems appropriate from time to time.
3.2 Deferral Election. For any Plan Year in which an Eligible Executive is eligible to participate, such Eligible Executive may elect on an Election Form to have a portion of the Compensation to be received by the Executive for such Plan Year deferred in accordance with the terms and conditions of the Plan. The Plan Administrator may provide for a separate election with respect to salary and annual bonus.
An Executive desiring to exercise such election shall, prior to the beginning of each Plan Year (or within 30 days after the date of the Eligible Executive’s initial eligibility for the Plan as determined by the Plan Administrator, if such eligibility commences other than at the beginning of a Plan Year), complete an Election Form indicating the percentage or amount of hisCompensation for such Plan Year that he elects to have deferred, provided that the Plan Administrator may extend the date for electing to defer an annual bonus under a Performance-Based Plan to the extent permitted by Section 409A. If the Eligible Executive’s election would result in a deferral greater than the maximum established by the Plan Administrator, any deferred amount shall be reduced to the maximum limit.
An election to defer Compensation must be filed with the Plan Administrator within the time period prescribed by the Plan Administrator. If a Participant fails to file a properly completed and duly executed Election Form with the Plan Administrator by the prescribed time, he will be deemed to have elected not to defer any Compensation under this Plan for the Plan Year, except to the extent the Plan Administrator in its sole discretion permits an extension of the election period. An Eligible Executive may not, after the applicable election date change (increase or decrease) the percentage or amount of Compensation he has elected to defer for a Plan Year.
At the time a Participant elects to defer Compensation, the Participant shall elect with respect to such deferral the time and manner in which the amount deferred (and any earnings thereon) will be distributed to the Participant. The Plan Administrator may provide that such election is a continuing election with respect to all amounts credited (and to be credited) to the Participant’s Account. The distribution elections, and any changes to such elections, shall be made in accordance with Article V.
The Plan Administrator may establish a minimum and maximum deferral limitation for a Plan Year for each group or class of Eligible Executives (which may be a dollar amount, a percentage of Compensation or some other limit) and may change such limitation from year to year, provided an Eligible Executive shall not be permitted to reduce his Compensation below the amount necessary to make required or elected contributions to employee benefit plans, required federal, state and local tax withholdings, and any other withholdings deemed necessary by the Plan Administrator or required by law.
The Participant may designate on the Election Form (or on a separate form provided by the Plan Administrator) a Beneficiary (or Beneficiaries) to receive payment of amounts in his Account in the event of his death. If a Participant fails to designate a Beneficiary under the Plan, the Beneficiary(ies) under the Prior Plan shall be deemed to be the Beneficiary(ies) designated under this Plan.
3.3 Deferral Subaccount. The Company shall establish a Deferral Subaccount for each Participant under the Plan. The initial amount credited to the Participant’s Deferral Subaccount under the Plan shall be the amount credited to the Participant’s Deferral Subaccount in the Prior Plan that is transferred to this Plan as provided in Section 4.2 below. Each Participant’s Deferral Subaccount shall thereafter be credited with the amounts of Compensation deferred by the Participant under this Plan. The timing and manner in which amounts are credited to a Participant’s Deferral Subaccount under this Plan shall be determined by the Plan Administrator in its discretion, but the deferral election shall be applied to each pay period in which the Participant has Compensation during his period of participation in the Plan. The Participant’s Deferral Subaccount shall be credited with interest at the Prime Rate, or the earnings under such other investment options that the Plan Administrator may establish, on each Annual Valuation Date based upon the amount credited to such Subaccount as of the preceding Annual Valuation Date, and at such other times, if any, as may be determined by the Plan Administrator.
3.4 Deferred Restricted Stock Subaccount. The Company shall establish a Deferred Restricted Stock Subaccount for each Participant under the Plan who has Deferred Vested Value Subaccount credits in the Prior Plan Transfer Account being transferred from the Prior Plan. The initial amount credited to the Participant’s Deferred Restricted Stock Subaccount under the Plan shall be the number of shares credited to the Participant’s Deferred Vested Value Subaccount in the Prior Plan that is transferred to this Plan as provided in Section 4.2 below and related dividends. No further deferrals will be allowed to the Deferred Restricted Stock Subaccount by the Participant under this Plan, unless the Plan administrator determines otherwise. The Deferred Restricted Stock Subaccount will be adjusted on each Annual Valuation Date (and at such other dates, if any, as may be determined by the Plan Administrator) as if it were invested in Shares to reflect any distributions, stock dividends, stock splits or similar actions with respect to the Shares since the preceding Annual Valuation Date (or such other date). The

Participant’s Deferred Restricted Stock Subaccount will be adjusted on each Annual Valuation Date (and at such other dates, if any, as may be determined by the Plan Administrator) to reflect the cash equivalent of any dividends with respect to the Shares since the preceding Annual Valuation Date (or such other date). The amounts credited to a Participant’s Deferred Restricted Stock Subaccount shall be distributed and subject to a further deferral election as provided in Section 5.1(g) below.
Effective as of the Spin-off Date (as defined in Section 3.5(c)(ii)), or as soon thereafter as is practical, the Company shall adjust the number of Shares credited to the Participant's Deferred Restricted Stock Subaccount to a number of Shares equal to the product of (i) the number of Shares credited to the Participant's Deferred Restricted Stock Subaccount as of the date of the distribution of the shares of Zep Inc. common stock to the stockholders of the Company (the "Distribution Date"), and (ii) the closing per share price of the Company common stock (trading with a due bill) on the New York Stock Exchange on the Distribution Date, divided by the closing per share price of the Company's common stock (on a when-issued basis) on the Distribution Date (or such other price as determined by the Plan Administrator to be appropriate and equitable.)
3.5 Transfer of Accounts to Zep Plan.
(a) With respect to Transferring Participants who participated in the Plan prior to the Spin-off Date, and who have made deferral elections under the Plan with respect to compensation which becomes payable on or after the Spin-off Date, the Company hereby transfers to the Zep Plan on the Spin-off Date, all rights with respect to amounts deferred (or to be deferred) pursuant to such deferral elections, and the Zep Plan will assume all obligations with respect to such deferrals.

(b) The Accounts of Transferring Participants in the Plan are hereby transferred to the Zep Plan on the Spin-off Date and the Zep Plan will assume all obligations with respect to the amounts credited to such Accounts.

The Participant may elect that the vested amount of his Retirement Account be distributed in a lump sum, or in annual payments for a period of up to ten (10) years, provided that if the balance of the Participant’s Account is less than $15,000, the Participant’s Account will automatically be paid in a lump sum. For example, under the 10-year annual payment method, the first year’s payment will equal one tenth (1/10) of the total Account, the second year’s will equal one ninth (1/9) of the remaining Account, and so forth. Subject to subsection (h) below, payment of the Participant’s Retirement Account shall be made (i) if the payment is in a lump sum, within 90 days after the event entitling the Participant to payment, or (ii) if the payment is in installments, commencing in the January following the event entitling the Participant to payment.
(c) The Participant may elect to have a Cash In-Service Account payable (or commence to be paid) during January of the year selected by the Participant on the Election Form (which initial payment date may not be earlier than two years after the end of the calendar year during which amounts are first credited to such Account), in a lump sum or in annual payments over a period of up to ten (10) years, in the manner provided in (a) above, as applicable; provided, that any subsequent deferrals to such designated Cash In-Service Account must be made no later than the end of the calendar year ending two years prior to such payment date; provided, further, that a Participant may only establish such number of Cash In-Service Accounts for his Account as may be permitted by the Plan Administrator (or his designee) and the Plan Administrator may increase the minimum deferral period for Cash In-Service Accounts. Notwithstanding the Participant’s elections under this Section 5.1(c), in the event the Participant becomes entitled to payment of his Retirement Account under subsection (b) above or to his Account under Section 5.2 below, the remaining balance of the Participant’s Account shall be payable in accordance with the provisions for payment under subsection (b) or under Section 5.2 (whether or not the Cash In-Service Account was in payment status at such time).
(d) The Participant will designate each Plan Year which portion of the Participant’s deferrals for such Plan Year shall be credited to the Participant’s Retirement Account and any Cash In-Service Accounts he has established. If a Participant’s Account is distributed in installments, the Account shall continue to be credited with deemed earnings, gains and losses in accordance with Article IV until the entire amount of the Account is distributed.
(e) A Participant may, not less than twelve (12) months prior to the payment dates of any Cash In-Service Accounts he has established under subsection (c) above, and with the approval of the Plan Administrator, elect to defer the date on which payment of any Cash In-Service Account shall commence and/or change the method of payment of such Cash In-Service Account, provided that, (i) after the initial election under subsection (c), a Participant may only make two election changes with respect to a particular Cash In-Service Account (after the second such election change, the election shall become irrevocable); (ii) except as otherwise permitted by Section 409A, the first in-service payment with respect to any such changed election must

be deferred at least 5 years from the date such payment would otherwise have been made, (iii) except as otherwise permitted by Section 409A, the election shall not become effective for 12 months.
A Participant may, not less than twelve (12) months prior to the event entitling the Participant to payment of his Retirement Account under subsection (b) above, elect to change the method of payment of the Participant’s Retirement Account, provided that (i) only two such changes are permitted and after the second such election change, the election is irrevocable; (ii) the payment date for the Participant’s Retirement Account will be deferred for 5 years for each election change, and (iii) the election shall not become effective for 12 months.
The change of election shall be made through a method established by the Plan Administrator.
(f) Notwithstanding the Participant’s payment elections under this Article V, the entire amount remaining in the Participant’s Account will be paid to the Participant in a lump sum in January of the calendar year in which the Participant will attain age 80.
(g) Unless the Participant elected otherwise as provided below, the vested amounts credited to his Deferred Restricted Stock Subaccount were automatically paid in a single payment in January 2008. Participants were allowed to elect on such form as provided by the Plan Administrator to receive payment (i) at the same time as the initial payment of his Retirement Account (assuming the Participant qualifies under subsection (b)), or (ii) during January of the year selected by the Participant for payment of his Restricted Stock In-Service Account. If the Participant terminates employment prior to the payment date of his Restricted Stock In-Service Account or event entitling the Participant to payment under subsection (b), payment of the Participant’s Deferred Restricted Stock Subaccount will be made within 90 days after the Participant’s termination of employment. All distributions from the Participant’s Deferred Restricted Stock Subaccount shall be made in a lump sum. The Participant may elect to change the time (but not form) of payment of his Restricted Stock Account, provided (i) such change in the time of payment shall be made not less than twelve (12) months prior to the event entitling the Participant to payment of his Restricted Stock Account; (ii) only two such changes are permitted and after the second such election change, the election is irrevocable; (iii) the payment date for the Participant’s Restricted Stock Account will be deferred for 5 years for each election change, and (iv) the election shall not become effective for 12 months.
The amounts credited to the Participant’s Deferred Restricted Stock Subaccount shall be subject to the Financial Hardship distribution rules of Section 5.5. The amounts credited to the Deferred Restricted Stock Subaccount that are treated as invested in Shares shall be paid in Shares.
(h) Notwithstanding the other provisions of this Article V, in the event a Participant who is a "key employee" (as determined by the Plan Administrator in accordance with procedures established by the Committee that are consistent with Section 409A) becomes entitled to payments upon separation from service, payments shall not commence until 6 months after such Participant separates from service and on such date the payments that would have been made during such six-month period shall be made.
5.2 Payment upon Certain Terminations of Service.
Subject to Section 5.1(h) above, the vested amount of the Participant’s Account (including any unpaid amounts in the Participant’s In-Service Accounts) will be paid in a lump sum as soon as practical after the end of the month following the date on which the Participant has a Termination of Service and the elections under Section 5.1 shall not be recognized, unless the Participant has attained age 55 at the time of such Termination of Service, or the Participant qualifies for Total and Permanent Disability under the terms of this Plan.
5.3 Payment at Death.
(a) While Actively Employed. In the event a Participant dies while actively employed, the entire amount of the Participant’s Account will become fully vested and will be paid in accordance with the Participant’s death election on the Election Form and, in the absence of such election, payment will be made in a lump sum.
(b) After Termination of Service. In the event a Participant dies subsequent to Termination of Service, the remaining amount of the Participant's Account, if any, will be distributed to the Participant's designated Beneficiaries in the form and at the time that payments would have been made had the Participant survived.
5.4 Payment at Disability.

In the event of the Participant’s Total and Permanent Disability (as defined in Section 2.38), the entire amount of the Participant’s Account will become fully vested and payment will be made in accordance with the Participant’s election under subsection (b). Once payment has commenced, payments will continue as elected regardless of any future change in the Participant’s disability status.
5.5 Financial Hardship Distribution.
Subject to approval by the Plan Administrator, the Participant may apply to withdraw, upon a showing of Financial Hardship, part or all of his vested Account. If the Plan Administrator determines that a distribution should be made on account of Financial Hardship, distribution from the Participant’s Account shall be made as soon as administratively practical. Such distribution shall not exceed the dollar amount necessary to satisfy the Financial Hardship plus amounts necessary to pay taxes reasonably anticipated as a result of the distribution, after taking into account the extent to which the Financial Hardship is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the Participant’s assets (to the extent the liquidation of such assets would not itself cause Financial Hardship).
ARTICLE VI

6.1 Plan Administrator. The Plan Administrator shall be the Company or such committee as may be designated by the Company to administer and manage the Plan. Members of any committee shall not be required to be employees of the Company or Participants. Action of the Plan Administrator may be taken with or without a meeting of committee members.

(a) To construe, interpret, and administer this Plan;
(b) To make allocations and determinations required by this Plan, and to maintain records relating to Participants’ Accounts;

6.3 Compensation, Indemnity and Liability. The Plan Administrator shall serve as such without bond and without compensation for services hereunder. All expenses of the Plan and the Plan Administrator shall be paid by the Company. If the Plan Administrator is a committee, no member of the committee shall be liable for any act or omission of any other member of the committee, nor for any act or omission on his own part, excepting his own willful misconduct.

The Company shall provide notice of any such withholding. Prior to making any payment, the Company may require such releases or other documents from any lawful taxing authority as it shall deem necessary.
ARTICLE VII
CLAIMS PROCEDURE
7.1 Claims for Benefits. If a Participant or beneficiary (hereafter, "Claimant") does not receive timely payment of any benefits which he believes are due and payable under the Plan, he may make a claim for benefits to the Plan Administrator. The claim for benefits must be in writing and addressed to the Plan Administrator or to the Company. If the claim for benefits is denied, the Plan Administrator shall notify the Claimant in writing within 90 days after the Plan Administrator initially received the benefit claim. However, if special circumstances require an extension of time for processing the claim, the Plan Administrator shall furnish notice of the extension to the Claimant prior to the termination of the initial 90-day period and such extension shall not exceed one additional, consecutive 90-day period. Any notice of a denial of benefits shall advise the Claimant of the basis for the denial, any additional material or information necessary for the Claimant to perfect his claim, and the steps which the Claimant must take to have his claim for benefits reviewed.
7.2 Appeals. Each Claimant whose claim for benefits has been denied may file a written request for a review of his claim by the Plan Administrator. The request for review must be filed by the Claimant within 60 days after he received the written notice denying his claim. The decision of the Plan Administrator will be made within 60 days after receipt of a request for review and shall be communicated in writing to the Claimant. Such written notice shall set forth the basis for the Plan Administrator’s decision. If there are special circumstances which require an extension of time for completing the review, the Plan Administrator’s decision shall be rendered not later than 120 days after receipt of a request for review.
ARTICLE VIII
AMENDMENT AND TERMINATION; CHANGE IN CONTROL
8.1 Amendments. Subject to Section 8.3, the Company (or its designee) shall have the right in its sole discretion to amend this Plan in any manner at any time; provided, however, that no such amendment shall reduce the Participant’s vested interest in his Account under Section 4.3 at that time. Any amendment shall be in writing and executed by a duly authorized officer of the Company. All Participants shall be bound by such amendment.
8.2 Termination of Plan. The Company expects to continue this Plan, but does not obligate itself to do so. Subject to Section 8.3, the Company reserves the right to discontinue and terminate the Plan at any time, in whole or in part, for any reason (including a change, or an impending change, in the tax laws of the United States or any State). If the Plan is terminated, the Plan Administrator shall be notified of such action in a writing executed by a duly authorized officer of the Company, and the Plan shall be terminated at the time therein set forth. The amounts credited to the Participants’ Accounts upon such termination shall become fully vested and shall be paid in a lump sum, provided that (i) the Company terminates at the same time any other arrangement that would be aggregated with the Plan under Section 409A; (ii) the Company does not adopt any other arrangement that would be aggregated with the Plan under Section 409A for three years; (iii) the payments upon such termination shall not commence until 12 months after the date of termination and all such payments are completed within 24 months after the date of termination; and (iv) such other requirements as may be imposed by Section 409A are satisfied. The termination of this Plan shall not result in the reduction of the amount credited to the Participant’s Account as of the date of such termination.
8.3 Change In Control Provisions.
(a) Amendment or Termination. Notwithstanding anything contained in this Article VIII or the Plan to the contrary, for a period of two (2) years following a Change in Control, this Plan shall not be terminated or amended to reduce, suspend or eliminate any Eligible Executive’s or Participant’s benefits or participation (or right to participate) provided under this Plan, including, without limitation, the benefits provided in Articles III and IV. Any amendment or termination of this Plan which a Participant reasonably demonstrates (i) was at the request of a third party who has indicated an intention or taken steps reasonably calculated to effect a Change in Control, or (ii) otherwise arose in connection with or in anticipation of a Change in Control, and which was not consented to in writing by the Participant shall be null and void, and shall have no effect whatsoever with respect to the Participant.

(b) Termination of Employment. Notwithstanding anything contained in this Plan to the contrary, if a Participant’s employment is terminated by the Company (other than for "Cause" as defined in (c) below) or by the Participant for any reason within two (2) years following a Change in Control, the Participant’s Account shall become fully vested and the Company shall, within five (5) days, pay to the Participant a lump sum cash payment of the full amount credited to his Account with earnings determined under Sections 3.3 and 4.1 credited thereto to the date of payment. If a Participant’s employment is terminated (i) for Cause (as defined in (c) below) within two (2) years following a Change in Control or (ii) for any reason more than two (2) years after a Change in Control, the provisions of Article IV shall apply to the distribution of the Participant’s Account.
(c) Cause. For purposes of Section 8.3(b), a termination for "Cause" is a termination of the Executive evidenced by a resolution adopted in good faith by the Company (or in the case of executive officers of the Company, by two-thirds of the Board of Directors of the Company) that the Participant (i) intentionally and continually failed to substantially perform his duties with the Company (other than a failure resulting from the Participant’s incapacity due to physical or mental illness) which failure continued for a period of at least thirty (30) days after a written notice of demand for substantial performance has been delivered to the Participant specifying the manner in which the Participant has failed to substantially perform, or (ii) intentionally engaged in conduct which is demonstrably and materially injurious to the Company, monetarily or otherwise; provided, however, that no termination of the Participant’s employment shall be for Cause as set forth in clause (ii) above until (x) there shall have been delivered to the Participant a copy of a written notice setting forth that the Participant was guilty of the conduct set forth in clause (ii) and specifying the particulars thereof in detail, and (y) the Participant shall have been provided an opportunity to be heard by the Board (with the assistance of the Participant’s counsel if the Participant so desires). No act, nor failure to act, on the Participant’s part, shall be considered "intentional" unless he has acted or failed to act, with an absence of good faith and without a reasonable belief that his action or failure to act was in the best interest of the Company. Notwithstanding anything contained in this Agreement to the contrary, in the case of any Participant who is a party to a Change in Control Agreement, no failure to perform by the Participant after a Notice of Termination (as defined in the Participant’s Change in Control Agreement) is given by the Participant shall constitute Cause for purposes of this Plan.
ARTICLE IX
MISCELLANEOUS
9.1 Limitation on Participant’s Rights. Participation in this Plan shall not give any Participant the right to be retained in the Company’s employ or the employ of any Employer, or any right or interest in this Plan or any assets of the Company other than as herein provided. The Company reserves the right to terminate the employment of any Participant without any liability for any claim against the Company under this Plan, except to the extent provided herein.
9.2 Benefits Unfunded. The benefits provided by this Plan shall be unfunded. All amounts payable under this Plan to Participants shall be paid from the general assets of the Company, and nothing contained in this Plan shall require the Company to set aside or hold in trust any amounts or assets for the purpose of paying benefits to Participants. This Plan shall create only a contractual obligation on the part of the Company, and Participants shall have the status of general unsecured creditors of the Company under the Plan with respect to amounts of Compensation they defer hereunder or any other obligation of the Company to pay benefits pursuant hereto. Any funds of the Company available to pay benefits pursuant to the Plan shall be subject to the claims of general creditors of the Company, and may be used for any purpose by the Company.
Notwithstanding the preceding paragraph, the Company may at any time transfer assets, including Shares, to a trust for purposes of paying all or any part of its obligations under this Plan. However, to the extent provided in the trust only, such transferred amounts shall remain subject to the claims of general creditors of the Company. To the extent that assets are held in a trust when a Participant’s benefits under the Plan become payable, the Plan Administrator shall direct the trustee to pay such benefits to the Participant from the assets of the trust.
9.3 Other Plans. This Plan shall not affect the right of any Executive or Participant to participate in and receive benefits under and in accordance with the provisions of any other employee benefit plans which are now or hereafter maintained by the Company, unless the terms of such other employee benefit plan or plans specifically provide otherwise.
9.4 Receipt or Release. Any payment to a Participant in accordance with the provisions of this Plan shall, to the extent thereof, be in full satisfaction of all claims against the Plan Administrator, the Company and any Employer, and the Plan Administrator may require such Participant, as a condition precedent to such payment, to execute a receipt and release to such effect.

9.5 Governing Law. This Plan shall be construed, administered, and governed in all respects in accordance with applicable federal law and, to the extent not preempted by federal law, in accordance with the laws of the State of Georgia. If any provisions of this instrument shall be held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions hereof shall continue to be fully effective.
9.6 Gender, Tense, and Headings. In this Plan, whenever the context so indicates, the singular or plural number and the masculine, feminine, or neuter gender shall be deemed to include the other. Headings and subheadings in this Plan are inserted for convenience of reference only and are not considered in the construction of the provisions hereof.
9.7 Successors and Assigns; Nonalienation of Benefits. This Plan shall inure to the benefit of and be binding upon the parties hereto and their successors and assigns; provided, however, that the amounts credited to the Account of a Participant shall not (except as provided in Section 6.4) be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, charge, garnishment, execution or levy of any kind, either voluntary or involuntary, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber, charge or otherwise dispose of any right to any benefits payable hereunder, including, without limitation, any assignment or alienation in connection with a separation, divorce, child support or similar arrangement, shall be null and void and not binding on the Plan or the Company. In addition to any obligations imposed by law upon any successor to the Company, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to substantially all of the business or assets of the Company to expressly agree to assume and perform this Agreement in the same manner that the Company would be required to perform it.
9.8 Combination With Other Plan. The Plan may be combined or merged with other deferred compensation plans of the Company and the Plan Administrator shall establish the terms and conditions relating to any such merger.
IN WITNESS WHEREOF, the Company has caused this Plan to be executed by its duly authorized officers as of the 28th day of June, 2019, to be effective on the Effective Date, except where otherwise noted.

APPENDIX A
PENSION PLAN MAKE-UP CONTRIBUTION CREDI T
(a) In General – Commencing January 1, 2005 (except where such amounts have already been credited under the Prior Plan), the Company shall for each Plan Year during the Make-Up Contribution Period (as defined in subsection (b) below) for each Pension Plan Participant (as defined in subsection (d) below) make a Make-Up Contribution credit (determined in accordance with subsection (b) below) for the benefit of such Pension Plan Participant. The Make-Up Contribution for each Plan Year shall be credited to the Pension Plan Participant’s Make-Up Contribution Subaccount. The Make-Up Contribution Subaccount shall become vested in accordance with the following schedule:
Completed Years of Service Vested Percentage Forfeited Percentage
Less than 5 years 0 100%
5 or more years 100% 0%
The Make-Up Contribution Subaccount shall be credited with interest at the Prime Rate on each Annual Valuation Date based upon the amount credited to such Subaccount as of the preceding Annual Valuation Date and at such other times, if any, as may be determined by the Plan Administrator. The vested Make-up Contribution Subaccount shall be credited to the Retirement Account and shall be distributed as provided in Article V. The Make-Up Contribution for each Plan Year shall be credited on the last day of the Plan Year, unless the Employer elects to make such credit on an earlier date. In order to be eligible to receive the Make-Up Contribution credit for the Plan Year, the Pension Plan Participant must be actively employed on the last day of the Plan Year and complete a Year of Service for such year. Any forfeiture of the credits to a Pension Plan Participant’s Make-Up Contribution Account shall be used to reduce future make-up contribution credits.
(b) Amount of Make-Up Contribution Credit
(i) The Make-Up Contribution credit for a Pension Plan Participant for the Plan Year shall be equal to the Present Value determined as of January 1, 2003 of the Annual Benefit Loss of the Pension Plan Participant divided by the number of years in the Make-Up Contribution Period, adjusted by the Discount Percentage. The Annual Benefit Loss for a Pension Plan Participant is the difference between (A) the aggregate annual retirement benefit (based upon the assumptions in subsection (b)(ii) below) the Pension Plan Participant was projected to receive at age 62 assuming that the Pension Plan and the 401(k) Plan (as defined in subsection (d) below) continued in operation in accordance with their terms as in effect on December 31, 2002, and (B) the aggregate annual retirement benefit (based upon the assumptions in subsection (b)(ii) below) the Pension Plan Participant was projected to receive at age 62 assuming that the Pension Plan is frozen at January 1, 2003 and the 401(k) Plan was amended effective January 1, 2003 to provide for a match of 60% on Elective Deferrals up to 6% of the Participant’s Annual Compensation. The Pension Plan Participant’s Make-Up Contribution Period is the period commencing January 1, 2003 and ending on the last day of the Plan Year in which the Pension Plan Participant attains age 62. The Present Value of the Annual Benefit Loss shall be determined by taking the amount of the Annual Benefit Loss on the date the Pension Plan Participant attains age 62 and discounting such amount to January 1, 2003 using an interest rate of 5.12% per year and the mortality table prescribed by the IRS in Rev. Rul. 95-6.
(ii) The Annual Benefit Loss shall be calculated using the following factors and assumptions:
A Pension Plan Participant’s service and compensation under the Pension Plan are frozen as of December 31, 2002.
The rate of Matching Contributions under the 401(k) Plan is increased effective January 1, 2003 to 60% on Elective Contributions up to 6% of a Participant’s Annual Compensation and the Pension Plan Participant will make sufficient Elective Deferrals to receive the maximum Matching Contributions.
A Pension Plan Participant’s Annual Compensation is his or her Annual Compensation for 2000, with an increase rate of 3% per year.
Pension Plan Participant’s Matching Contribution Account Balance in the 401(k) Plan as of December 31, 2001, will be projected to age 62 with earnings of 6% per year.
401(k) Plan compensation limit of $200,000 applies for 2002 and prior years and will increase by 3% per year.
Annuity and lump sum conversions are based upon a 5.12% annual interest rate and the mortality table prescribed by the IRS in Rev. Rul. 95-6.
The annual retirement benefit from the 401(k) Plan is based solely upon the Pension Plan Participant’s Matching Contribution Account (adjusted as provided herein) and not the individual’s other accounts under Section 4.1 of the 401(k) Plan.

(iii) The Make-Up Contribution to be credited to a Pension Plan Participant for a Plan Year shall be increased over the amount credited for the prior Plan Year by the Discount Percentage to account for the passage of a year and the related foregone interest earnings potential.
(c) Change of Eligible Status – If a Pension Plan Participant is treated as a Highly Compensated Employee under the 401(k) Plan for a Plan Year, the Pension Plan Participant shall be eligible to receive a Make-Up Contribution credit for such Plan Year. If the Pension Plan Participant who is a Highly Compensated Employee for a Plan Year ceases to be a Highly Compensated Employee for a subsequent Plan Year, then the Pension Plan Participant shall be ineligible to receive a Make-Up Contribution credit for such later Plan Year. If a Pension Plan
Participant ceases to be eligible to participate in the 401(k) Plan for a Plan Year, the Pension Plan Participant shall not be eligible to receive a Make-Up Contribution for such Plan Year.
(d) Definitions – The following definitions shall apply for purposes of this Appendix A:
(i) Pension Plan – The Acuity Brands, Inc. Pension Plan, as amended through December 31, 2002.
(ii) Pension Plan Participant – A participant in the Pension Plan on December 31, 2002 who (i) is an active Employee of an Employer on December 31, 2002, (ii) will be considered a Highly Compensated Employee of the Employer for 2003 or in a subsequent Plan Year for which he would be eligible for a Make-Up Contribution, and
(iii) is a Participant in the 401(k) Plan for the Plan Year commencing on January 1, 2003 and any subsequent Plan Year for which a Make-Up Contribution credit is to be made.
(iv) Discount Percentage – A percentage rate equal to 5.12% per year.
(v) 401(k) Plan – The Acuity Brands, Inc. 401(k) Plan for Corporate Employees as amended through December 31, 2002.
(e) Discretion of Company – The Company shall have the discretion to determine the amount of the Make-Up Contribution for Pension Plan Participants each Plan Year and the Company’s determination of the Make-Up Contribution credit shall be final and binding upon all parties.
(f) Amendment – This Appendix A may be amended by the Company in accordance with the usual rules for amendment of the Plan in Section 8.1.

APPENDIX B
SERP MAKE-UP CONTRIBUTION CREDIT
(a) In General – Commencing January 1, 2005 (except where such amounts have already been credited under the Prior Plan), the Company shall for each Plan Year during the SERP Make-Up Contribution Period (as defined in subsection (b) below) for each SERP Plan Participant (as defined in subsection (d) below) make a SERP Make-Up Contribution credit (determined in accordance with subsection (b) below) for the benefit of such SERP Plan Participant. The SERP Make-Up Contribution for each Plan Year shall be credited to the SERP Plan Participant’s SERP Make-Up Contribution Subaccount. The SERP Make-Up Contribution Subaccount shall at all times be fully vested and nonforfeitable. The SERP Make-Up Contribution Subaccount shall be credited with interest at the Prime Rate on each Annual Valuation Date based upon the amount credited to such Subaccount as of the preceding Annual Valuation Date and at such other times, if any, as may be determined by the Plan Administrator. The SERP Make-up Contribution Subaccount shall be credited to the Retirement Account and shall be distributed as provided in Article V. The SERP Make-Up Contribution for each Plan Year shall be credited on the last day of the Plan Year, unless the Employer elects to make such credit on an earlier date. In order to be eligible to receive the SERP Make¬Up Contribution credit for the Plan Year, the SERP Plan Participant must be actively employed on the last day of the Plan Year and complete a Year of Service for such year.
(b) Amount of SERP Make-Up Contribution Credit
(i) The SERP Make-Up Contribution credit for a SERP Plan Participant for the Plan Year shall be equal to the Present Value determined as of January 1, 2003 of the Annual Benefit Loss of the SERP Plan Participant divided by the number of years in the SERP Make-Up Contribution Period, adjusted by the Discount Percentage. The Annual Benefit Loss for a SERP Plan Participant is the difference between (A) the aggregate annual supplemental retirement benefit (based upon the assumptions in subsection (b)(ii) below) the SERP Plan Participant was projected to receive at age 60 assuming that the Pension Plan, the Current SERP (as defined in subsection (d) below) and the EDCP (as defined in subsection (d) below) continued in operation in accordance with their terms as in effect on August 31, 2002, and (B) the aggregate supplemental annual retirement benefit (based upon the assumptions in subsection (b)(ii) below) the SERP Plan Participant is projected to receive at age 60 from the New SERP. The Pension Plan Participant’s SERP Make-Up Contribution Period is the period commencing January 1, 2003 and ending on the last day of the Plan Year in which the SERP Plan Participant attains age 60. The Present Value of the Annual Benefit Loss shall be determined by taking the amount of the Annual Benefit Loss on the date the SERP Plan Participant attains age 60 and discounting such amount to January 1, 2003 using an interest rate of 5.12% per year and the mortality table prescribed by the IRS in Rev. Rul. 95-6.
(ii) The Annual Benefit Loss shall be calculated using the following factors and assumptions:
A SERP Plan Participant’s service and compensation under the Pension Plan is frozen as of December 31, 2002.
A SERP Plan Participant’s Annual Compensation is his or her Annual Compensation for 2002, with an increase rate of 3% per year.
(iii) The SERP Make-Up Contribution to be credited to a SERP Plan Participant for a Plan Year shall be increased over the amount credited for the prior Plan Year by the Discount Percentage to account for the passage of a year and the related foregone interest earnings potential.
(c) Discretion of Company – The Company shall have the discretion to determine the amount of the SERP Make-Up Contribution for SERP Plan Participants each Plan Year and the Company’s determination of the SERP Make-Up Contribution credit shall be final and binding upon all parties.
(d) Definitions – The following definitions shall apply for purposes of this Appendix B:
(i) Pension Plan – The Acuity Brands, Inc. Pension Plan, as amended through December 31, 2002.
