Exhibit 10(iii)A(32)

ACUITY BRANDS, INC.

SEVERANCE AGREEMENT

THIS AGREEMENT (the “Agreement”), made and entered into as of this              day of                     , 2003, by and between ACUITY BRANDS, INC., a Delaware corporation (the “Company”), and                                                       (the “Executive”).

W I T N E S S E T H:

WHEREAS, Executive is a key employee of the Company and an integral part of the Company’s management; and

WHEREAS, the Company desires to provide the Executive with certain benefits if the Executive’s employment is terminated involuntarily under certain circumstances; and

WHEREAS, the Company and the Executive have determined that it is in their mutual best interests to enter into this Agreement;

NOW, THEREFORE, the parties hereby agree as follows:

Unless earlier terminated as hereinafter provided, this Agreement shall commence on the date hereof, shall be for a rolling, two-year term (the “Term”), and shall be deemed to extend automatically, without further action by either the Company or Executive, each day for an additional day, such that the remaining term of the Agreement shall continue to be two years; provided, however, that either party may, by written notice to the other, cause this Agreement to cease to extend automatically and, upon such notice, the “Term” of this Agreement shall be the two-year period following the date of such notice and this Agreement shall terminate upon the expiration of such Term. This Agreement shall not be considered an employment agreement and in no way guarantees Executive the right to continue in the employment of the Company or its affiliates. Executive’s employment is considered employment at will, subject to Executive’s right to receive payments and benefits upon certain terminations of employment as provided below.

As of the date hereof, this Agreement is intended to, and shall, supersede and replace in their entirety the severance benefits provided under the Executive’s Employment Agreement dated                         .

2.1 “Board” or “Board of Directors” — The Board of Directors of Acuity Brands, Inc., or its successor.

2.2 “Cause” — The involuntary termination of Executive by the Company for the following reasons shall constitute a termination for Cause:

(a) If termination shall have been the result of an act or acts by the Executive which have been found in an applicable court of law to constitute a felony (other than traffic-related offenses);

(b) If termination shall have been the result of an act or acts by the Executive which are in the good faith judgment of the Company deemed to be in violation of law or of written policies of the Company and which result in material injury to the Company;

(c) If termination shall have been the result of an act or acts of dishonesty by the Executive resulting or intended to result directly or indirectly in gain or personal enrichment to the Executive at the expense of the Company; or

(d) Upon the continued failure by the Executive substantially to perform the duties reasonably assigned to Executive given Executive’s training and experience (other than any such failure resulting from incapacity due to mental or physical illness not constituting a Disability, as defined herein), after a demand in writing for substantial performance of such duties is delivered by the Company, which demand specifically identifies the manner in which the Company believes that the Executive has not substantially performed his duties, and such failure results in material injury to the Company.

2.3 “Company” — Acuity Brands, Inc., a Delaware corporation, or any successor to its business and/or assets.

2.4 “Date of Termination” — The date specified in the Notice of Termination (which may be immediate) as the date upon which the Executive’s employment with the Company is to cease.

2.5 “Disability” — Disability shall have the meaning ascribed to such term in the Company’s long-term disability plan covering the Executive, or in the absence of such plan, a meaning consistent with Section 22(e)(3) of the Internal Revenue Code of 1986, as amended.

2.6 “Notice of Termination” — A written notice from one party to the other party specifying the Date of Termination and setting forth in reasonable detail the facts and circumstances relating to the basis for termination of Executive’s employment.

2.7 “Severance Period” — A period equal to the lesser of (i) eighteen (18) months from the Executive’s Date of Termination or (ii) the number of months (rounded to the nearest month) from the Executive’s Date of Termination until the date he attains age 65; provided, however, that the Severance Period shall in no event be less than six (6) months.

2.8 “Severance Protection Agreement” — An agreement between Executive and the Company providing for the payment of compensation and benefits to Executive in the event of Executive’s termination of employment under certain circumstances following a “change in control” of the Company (as defined in such agreement).

This Agreement provides for the payment of compensation and benefits to Executive in the event his employment is involuntarily terminated by the Company without Cause. If Executive is terminated by the Company for Cause, dies, incurs a Disability or voluntarily terminates employment, this Agreement shall terminate, and Executive shall be entitled to no payments of compensation or benefits pursuant to the terms of this Agreement; provided that in such events, Executive will be entitled to whatever benefits are payable pursuant to the terms of any health, life insurance, disability, welfare, retirement, deferred compensation, or other plan or program maintained by the Company.

If, as a result of Executive’s termination of employment, Executive becomes entitled to compensation and benefits under this Agreement and under a Severance Protection Agreement, Executive shall be entitled to receive benefits under whichever agreement provides Executive the greater aggregate compensation and benefits (and not under the other agreement) and there shall be no duplication of benefits.

If Executive’s employment is involuntarily terminated by the Company during the term of this Agreement without Cause (and such termination does not arise as a result of Executive’s death or Disability), the Executive shall be entitled to the compensation and benefits described below, provided that Executive, as described in Section 4.7, executes a valid release of claims in such form as may be required by the Company. In the event Executive is terminated without Cause, the Compensation Committee of the Board of Directors may, in its discretion and to provide equitable treatment, grant benefits to Executive in addition to those provided below in circumstances where Executive suffers a diminution of projected benefits as a result of Executive’s termination prior to attainment of age 65, including without limitation, additional retirement benefits and acceleration of long-term incentive awards.

4.1 Base Salary. Executive shall continue to receive his Base Salary (subject to withholding of all applicable taxes) for the entire Severance Period (as defined in Section 2.7 above), payable in the same manner as it was being paid on his Date of Termination.

4.2 Annual Bonus. Executive shall be paid a bonus in an amount equal to the greater of (i) the annual incentive bonus that would be paid or payable to Executive for the fiscal year of the Company during which Executive’s Date of Termination occurs under the Company’s annual incentive plan (“Incentive Plan”), assuming the target level(s) of performance had been met for such fiscal year, multiplied by a fraction (the “Pro Rata

-3-

Fraction”), the numerator of which is the number of days that have elapsed in the then current fiscal year through Executive’s Date of Termination and the denominator of which is 365, or (ii) the annual incentive bonus that would be paid or payable to Executive for the fiscal year of the Company during which Executive’s Date of Termination occurs under the Incentive Plan based upon the Company’s actual performance for such fiscal year, multiplied by the Pro Rata Factor. The bonus amount determined pursuant to Section 4.2(i) shall be paid to Executive within ten (10) days of Executive’s Date of Termination and any additional amount payable pursuant to Section 4.2(ii) shall be payable at the same time as bonuses are payable to other executives under the Incentive Plan.

4.3 Restricted Stock. Any Restricted Stock granted to Executive under the Acuity Brands, Inc. Long-Term Incentive Plan (“LTIP”) for which the specific performance targets have been achieved and a Vesting Start Date (as defined in the agreement granting the Restricted Stock to Executive, the “Restricted Stock Agreement”) has been established as of Executive’s Date of Termination shall become fully vested and nonforfeitable as of Executive’s Date of Termination and subject to the proviso at the end of this sentence, all Restricted Stock for which a Vesting Start Date has not been established shall be immediately forfeited; provided, that if the Restricted Stock Agreement granting the Restricted Stock to Executive provides for more favorable continued vesting after Executive’s Date of Termination, the provisions of such Restricted Stock Agreement shall apply to the vesting of Executive’s Restricted Stock after Executive’s termination. The Vested Value (as defined in the Restricted Stock Agreement) of the shares of Restricted Stock vesting pursuant to this Section 4.3 shall be delivered to Executive in the manner provided in Section 2.2 of the Restricted Stock Agreement within ten (10) days of Executive’s Date of Termination, using Executive’s Date of Termination as the date for determining the Vested Value.

4.4 Health Care, Life Insurance and Long-Term Disability Coverages. The health care (including dental and vision coverage, if applicable), term life insurance and long-term disability coverages provided to Executive at his Date of Termination shall be continued at the same level as for active executives and in the same manner as if his employment had not terminated, beginning on the Date of Termination and ending on the last day of the Severance Period. Any additional coverages Executive had at termination, including dependent coverage, will also be continued for such period on the same terms, to the extent permitted by the applicable policies or contracts. Any costs Executive was paying for such coverages at the time of termination shall be paid by Executive by separate check payable to the Company each month in advance or, at Executive’s election, may be deducted from his Base Salary payments under Section 4.1. If the terms of any benefit plan referred to in this Section, or the laws applicable to such plan do not permit continued participation by Executive, then the Company will arrange for other coverage(s) satisfactory to Executive at Company’s expense which provides substantially similar benefits or, at Executive’s election, will pay Executive a lump sum amount equal to the annual costs of such coverage(s) for the Severance Period. A benefit provided under this Section 4.2 shall cease if Executive obtains other employment and, as a result of such employment, health care, life insurance or long-term disability benefits are available to Executive.

-4-

4.5 Outplacement Services. Executive will be provided with customary outplacement services by an outplacement firm selected by the Company for the Severance Period, provided that the Company’s total cost for such services shall not exceed an amount equal to ten percent (10%) of Executive’s Base Salary.

4.6 Other Benefits. Except as expressly provided herein, all other fringe benefits provided to Executive as an active employee of the Company (e.g., 401(k) plan, AD&D, car allowance, club dues, etc.), shall cease on his Date of Termination, provided that any conversion or extension rights applicable to such benefits shall be made available to Executive at his Date of Termination or when such coverages otherwise cease at the end of the Severance Period. Except as expressly provided herein, for all other plans sponsored by the Company, the Executive’s employment shall be treated as terminated on his Date of Termination and Executive’s right to benefits shall be determined under the terms of such plans; provided, however, in no event will Executive be entitled to severance payments or benefits under any other severance plan, policy, program or agreement of the Company, except to the extent Executive is covered by a Severance Protection Agreement related to a change in control of the Company.

4.7 Release of Claims. To be entitled to any of the compensation and benefits described above in this Section 4, Executive shall sign a release of claims substantially in the form attached hereto as Exhibit A. No payments shall be made under this Section 4 until such release has been properly executed and delivered to the Company and until the expiration of the revocation period, if any, provided under the release. If the release is not properly executed by the Executive and delivered to the Company within the reasonable time periods specified in the release, the Company’s obligations under this Section 4 will terminate.

5.1 Purpose and Reasonableness of Provisions. Executive acknowledges that, prior to and during the Term of this Agreement, the Company has furnished and will furnish to Executive Trade Secrets and Confidential Information which could be used by Executive on behalf of a competitor of the Company or other person to the Company’s substantial detriment. Moreover, the parties recognize that Executive during the course of his employment with the Company may develop important relationships with customers and others having valuable business relationships with the Company. In view of the foregoing, Executive acknowledges and agrees that the restrictive covenants contained in this Section 5 and in Exhibit B hereto are reasonably necessary to protect the Company’s legitimate business interests and good will.

5.2 Trade Secrets and Confidential Information. Executive agrees that he shall protect the Company’s Trade Secrets (as defined in Section 5.10(b) below) and Confidential Information (as defined in Section 5.10(a) below) and shall not disclose to any Person, or otherwise use or disseminate, except in connection with the performance of his duties for the Company, any Trade Secrets or Confidential Information; provided, however, that Executive

-5-

may make disclosures required by a valid order or subpoena issued by a court or administrative agency of competent jurisdiction, in which event Executive will promptly notify the Company of such order or subpoena to provide the Company an opportunity to protect its interests. Executive’s obligations under this Section 5.2 shall apply during his employment and after his termination of employment, and shall survive any expiration or termination of this Agreement, provided that Executive may after such expiration or termination disclose Confidential Information with the prior written consent of the then-serving Chief Executive Officer of the Company.

The Executive, during employment with the Company, will not offer, disclose or use on Executive’s own behalf or on behalf of the Company, any information Executive received prior to employment by the Company, which was supplied to Executive confidentially or which Executive should reasonably know to be confidential, to any persons, organization or entity other than the Company without the written approval of such person, organization or entity.

5.3 Return of Property. Upon the termination of his employment with the Company, Executive agrees to deliver promptly to the Company all Company files, customer lists, management reports, memoranda, research, Company forms, financial data and reports and other documents (including all such data and documents in electronic form) supplied to or created by Executive in connection with his employment hereunder (including all copies of the foregoing) in his possession or control, and all of the Company’s equipment and other materials in his possession or control. Executive’s obligations under this Section 5.3 shall survive any expiration or termination of this Agreement.

5.4 Inventions. The Executive does hereby assign to the Company the entire right, title and interest in any Invention that is made and/or conceived, either solely or jointly with others, during Executive’s employment with the Company. The Executive agrees to promptly disclose to the Company all such Inventions. The Executive will, if requested, promptly execute and deliver to the Company a specific assignment of title for an Invention and will, at the expense of the Company, take all reasonably required action by the Company to patent, copyright or otherwise protect the Invention.

5.5 Non-Competition. The Executive agrees that while employed by the Company and for a period equal to the Severance Period thereafter, but only for such period as Base Salary is paid to Executive under Section 4.1 hereto, Executive shall comply with the non-competition restrictions attached hereto as Exhibit B. The parties hereto recognize that Executive may experience periodic material changes in his job title and/or to the principal duties, responsibilities or services that he is called upon to perform on the behalf of the Company. If Executive experiences such a material job change, the parties shall, as soon as is practicable, enter into a signed, written addendum to Exhibit B hereto reflecting such material change. Upon execution, any such written modification to Exhibit B shall represent an enforceable amendment to this Agreement and shall augment and supplant the definition of the term Executive Services set forth in Exhibit B hereto.

5.6 Non-Solicitation of Customers/Suppliers. The Executive agrees that during the course of employment with the Company, and for a period equal to the Severance Period thereafter, but only for such period as Base Salary is paid to Executive under Section 4.1 hereto, the Executive will not directly or indirectly (i) divert or attempt to divert any person, concern or entity which is furnished products or services by the Company from doing business with the Company or otherwise change its relationship with the Company; or (ii) induce or attempt to induce any customer, supplier or service provider to cease being a customer, supplier or service provider of the Company or to otherwise change its relationship with the Company.

5.7 Non-Solicitation of Employees. The Executive agrees that during the course of employment with the Company, and for a period equal to the Severance Period thereafter, but only for such period as Base Salary is paid to Executive under Section 4.1 hereto, the Executive shall not, directly or indirectly, whether on behalf of the Executive or others, solicit, lure or attempt to hire away any of the employees of the Company with whom the Executive interacted while employed with the Company.

5.8 Injunctive Relief. Executive acknowledges that if he breaches or threatens to breach any of the provisions of this Section 5, his actions may cause irreparable harm and damage to the Company which could not be compensated in damages. Accordingly, if Executive breaches or threatens to breach any of the provisions of this Section 5, the Company shall be entitled to seek injunctive relief, in addition to any other rights or remedies the Company may have. The existence of any claim or cause of action by Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of Executive’s agreements under this Section 5.

5.9 Provisions Severable. If any provision in this Section 5 and/or Exhibit B hereto is determined to be in violation of any law, rule or regulation or otherwise unenforceable, and cannot be modified to be enforceable, such determination shall not affect the validity of any other provisions of this Agreement, but such other provisions shall remain in full force and effect. Each and every provision, paragraph and subparagraph of this Section 5, including Exhibit B hereto, is severable from the other provisions, paragraphs and subparagraphs and constitutes a separate and distinct covenant.
