                  2001 NONEMPLOYEE DIRECTORS' STOCK OPTION PLAN

1.       PURPOSE

         (a)      The purpose of this Plan is to provide a means by which
nonemployee directors of Acuity Brands, Inc. (the "Company") may be given an
opportunity to purchase stock of the Company.

         (b)      The Company, by means of the Plan, seeks to secure and retain
the services of persons best qualified to serve as directors of the Company and
to provide incentives for such persons to exert maximum efforts for the success
of the Company.

         (c)      The Company intends that the options issued under the Plan
shall be options which do not qualify as incentive stock options for purpose of
Section 422 of the Code.

         (d)      In connection with the spin-off of the Company by National
Service Industries, Inc. ("NSI"), options will be granted under this Plan as
Replacement Options, as hereinafter defined, to former nonemployee directors of
NSI who do not continue to be nonemployee directors of NSI following the
spin-off.

                  (a)      To construe and interpret the Plan and any Option, to
         construe and interpret any condition or restrictions imposed on Shares
         acquired pursuant to the exercise of an Option, to define the terms
         used herein and to establish, amend, and revoke rules and regulations
         for administration of the Plan. The Board in the exercise of this
         power, may correct any defect, omission, or inconsistency in the Plan

         necessary or expedient to make the Plan fully effective.

                  (c)      Generally, to exercise such powers and to perform

shares of stock or other securities to which such Shares are adjusted upon a

for the purposes of the Plan, out of its authorized but unissued Shares or out
of Shares held in the Company's treasury, or partly out of each, such number of
Shares as shall be determined by the Board.

         4.2      Whenever any outstanding Option or portion thereof expires, is
forfeited, is cancelled or is otherwise terminated for any reason (other than
upon the exercise of the Option or upon the surrender of the Option pursuant to
Section 6), the Shares allocable to the cancelled or otherwise terminated Option
or portion thereof may again be the subject of Options granted hereunder.

5.       OPTION GRANTS FOR NONEMPLOYEE DIRECTORS

         5.1      Initial Grant. An Option to purchase 1,500 Shares, subject to
adjustment as provided in Section 7, shall be granted to each Nonemployee
Director on December 3, 2001. The purchase price of each Option shall be as
provided in this Section 5 and such Options shall be evidenced by an Agreement
containing such other terms and conditions not inconsistent with the provisions
of this Plan as determined by the Board.

         5.2      Annual Grant. An Option to purchase 1,500 Shares, subject to
adjustment as provided in Section 7, shall be granted to each Nonemployee
Director on the date of the

                                       4

<PAGE>

annual meeting of the stockholders of the Company each year that the Plan
remains in effect pursuant to its terms. The purchase price of each Option shall
be as provided in this Section 5 and such Options shall be evidenced by an
Agreement containing such other terms and conditions not inconsistent with the
provisions of this Plan as determined by the Board.

         5.3      Purchase Price. The purchase price for Shares under each
Option, other than Replacement Options, shall be equal to 100% of the Fair
Market Value of a Share on the date the Option is granted.

         5.4      Duration. Options shall be for a term of ten (10) years,
unless terminated earlier as follows:

         (a) if an Optionee's service as a Director terminates for Cause, the
Options granted to the Optionee hereunder shall immediately terminate in full
and no rights thereunder may be exercised;

         (b) if an Optionee's service as a Director terminates for any reason
other than Cause, the Optionee (or any guardian, legal representative, heir or
successor of the Optionee) may for a period of three (3) years after such
termination exercise his or her Options to the extent, and only to the extent,
that such Options or portions thereof were vested and exercisable as of the date
the Optionee's service as a Director terminated, after which time the Options
shall automatically terminate in full.

         This Section 5.4 shall not be construed to extend the term of any
Option or to permit anyone to exercise any Option after expiration of its term,
nor shall it be construed to increase the number of Shares as to which any
Option is exercisable from the amount exercisable on the date of termination of
the Optionee's service as a Director.

         5.5      Vesting. Subject to Section 6, each Option shall be
exercisable in whole or in part at any time after one (1) year from the date of
grant of the Option.

         5.6      Non-transferability. No Option granted hereunder shall be
transferable by the Optionee to whom granted otherwise than (i) by will or the
laws of descent and distribution and (ii) upon such terms and conditions as the
Company may establish, to immediate family members of the Optionee or to a
trust, partnership or similar vehicle for the benefit of such immediate family
members (collectively, the "Permitted Transferees"). For purposes of this
Section 5.6, "immediate family" means an Optionee's spouse, parents, children,
grandchildren and spouse of children and grandchildren (including adopted
children and grandchildren, as the case may be). A Permitted Transferee may not
further transfer the Option. An Option transferred pursuant to this Section 5.6
shall remain subject to all of the provisions of the Plan and any Agreement with
respect to such Option and may not be exercised by a Permitted Transferee unless
and until all legal or regulatory approvals, listings, registrations,
qualifications or other clearances as determined by the Company to be required
or appropriate have been obtained. An Option may be exercised during the
lifetime of such Optionee only by the Optionee or his beneficiary or guardian or
legal representative or, if applicable, by Permitted Transferees. The terms of
such Option shall be final, binding

                                       5

<PAGE>

and conclusive upon the beneficiaries, executors, administrators, heirs,
successors, and Permitted Transferees of the Optionee.

         5.7      Method of Exercise. The exercise of an Option shall be made
only by a written notice delivered in person or by mail to the Secretary of the
Company at the Company's principal executive office, specifying the number of
Shares to be purchased and accompanied by payment therefor and otherwise in
accordance with the Agreement pursuant to which the Option was granted. The
purchase price for any Shares purchased pursuant to the exercise of an Option
shall be paid in full upon such exercise in cash, by check or by transferring
Shares to the Company upon such terms and conditions as determined by the Board.
The written notice pursuant to this Section 5.7 may also provide instructions
from the Optionee to the Company that upon receipt of the purchase price in cash
from the Optionee's broker or dealer, designated as such on the written notice,
in payment for any Shares purchased pursuant to the exercise of an Option, the
Company shall issue such Shares directly to the designated broker or dealer. Any
Shares transferred to the Company as payment of the purchase price under an
Option shall be valued at their Fair Market Value on the day preceding the date
of exercise of such Option. If requested by the Board, the Optionee shall
deliver the Agreement evidencing the Option to the Secretary of the Company who
shall endorse thereon a notation of such exercise and return such Agreement to
the Optionee. No fractional Shares (or cash in lieu thereof) shall be issued
upon exercise of an Option and the number of Shares that may be purchased upon
exercise shall be rounded to the nearest number of whole Shares.

         5.8      Rights of Optionees. No Optionee shall be deemed for any
purpose to be the owner of any Shares subject to any Option unless and until (i)
the Option shall have been exercised pursuant to the terms thereof, (ii) the
Company shall have issued and delivered the Shares to the Optionee, and (iii)
the Optionee's name shall have been entered as a stockholder of record on the
books of the Company. Thereupon, the Optionee shall have full voting, dividend,
and other ownership rights with respect to such Shares.

         5.9      Replacement Options. Notwithstanding the above, each
Replacement Option for an option granted under the National Service Industries,
Inc. 1992 Nonemployee Directors' Stock Option Plan shall reflect the adjustments
provided for in the Employee Benefits Agreement and shall have the same material
terms and conditions as the option it replaces, as determined by the Board.

6.       EFFECT OF CHANGE IN CONTROL

         Notwithstanding anything contained in the Plan or an Agreement to the
contrary, in the event of a Change in Control, (i) all Options outstanding on
the date of such Change in Control shall become immediately and fully
exercisable and (ii) an Optionee will be permitted to surrender for cancellation
within sixty (60) days after such Change in Control, any Option or portion of an
Option to the extent not yet exercised and the Optionee will be entitled to
receive a cash payment in an amount equal to the excess, if any, of (x) the
greater of (1) the Fair Market Value, on the date preceding the date of
surrender, of the Shares subject to the Option or portion thereof surrendered or
(2) the Adjusted Fair Market Value of

                                       6

<PAGE>

the Shares subject to the Option or portion thereof surrendered, over (y) the
aggregate purchase price for such Shares under the Option or portion thereof
surrendered; provided, however, that in the case of an Option granted within six
(6) months prior to the Change in Control, the Optionee shall be entitled to
surrender for cancellation his or her Option during the sixty (60) day period
commencing upon the expiration of six (6) months from the date of grant of any
such Option.

7.       ADJUSTMENT UPON CHANGES IN CAPITALIZATION

         7.1      Subject to Section 8, in the event of a Change in
Capitalization, the Board shall conclusively determine the appropriate
adjustments, if any, to the (i) maximum number and class of Shares or other
stock or securities with respect to which Options may be granted under the Plan,
(ii) the number and class of Shares or other stock or securities which are to be
subject to Options to be granted under Section 5; and (iii) the number and class
of Shares or other stock or securities which are subject to outstanding Options
granted under the Plan, and the purchase price therefor, if applicable;
provided, however, that any stock adjustment in the Shares or other stock or
securities subject to an outstanding Option (including any adjustments in the
purchase price) shall be made only to the extent necessary to maintain the
proportionate interest of the Optionee and preserve, without exceeding, the
value of such Option.

         7.2      If, by reason of a Change in Capitalization, an Optionee shall
be entitled to exercise an Option with respect to new, additional or different
shares of stock or securities, such new, additional or different shares shall
thereupon be subject to all of the conditions which were applicable to the
Shares subject to the Option, as the case may be, prior to such Change in
Capitalization.

8.       EFFECT OF CERTAIN TRANSACTIONS

         Subject to Section 6, in the event of (i) the liquidation or
dissolution of the Company or (ii) a merger or consolidation of the Company (a
"Transaction"), the Plan and the Options issued hereunder shall continue in
effect in accordance with their respective terms and each Optionee shall be
entitled to receive in respect of each Share subject to any outstanding Option,
upon exercise of such Option, the same number and kind of stock, securities,
cash, property, or other consideration that each holder of a Share was entitled
to receive in the Transaction in respect of a Share. In the event that, after a
Transaction, there occurs any change of a type described in Section 2.5 with
respect to the shares of the surviving or resulting corporation, then
adjustments similar to, and subject to the same conditions as, those in Section
7 shall be made by the Board.

9.       TERMINATION AND AMENDMENT OF THE PLAN

         The Plan shall terminate on the day prior to the tenth anniversary of
the date the Board approved the Plan, and no Option may be granted thereafter.
The Board may sooner terminate the Plan and the Board may from time to time
amend, modify, or suspend the Plan; provided, however that:

                                       7

<PAGE>

         (a)      Except as provided in Sections 7 and 8, no such amendment,
modification, suspension, or termination shall impair or adversely alter any
Options or rights theretofore granted under the Plan, except with the consent of
the Optionee, nor shall any amendment, modification, suspension, or termination
deprive any Optionee of any Shares which he or she may have acquired through or
as a result of the Plan;

         (b)      To the extent required by applicable law, regulation or rule,
no amendment shall be effective unless approved by the stockholders of the
Company in accordance with applicable law and regulations at an annual or
special meeting held within twelve (12) months before or after the date of
adoption of such amendment.

10.      NON-EXCLUSIVITY OF THE PLAN

         (a)      The adoption of the Plan by the Board shall not be construed
as amending, modifying or rescinding any previously approved compensation
arrangement or as creating any limitations on the power of the Board to adopt
such other compensation arrangements as it may deem desirable, including,
without limitation, the granting of stock options otherwise than under the Plan,
and such arrangements may be either applicable generally or only in specific
cases.

         (b)      Nothing contained in this Plan prohibits a Nonemployee
Director from being appointed as an officer or employee of the Company at any
time; nor does anything contained in this Plan specifically require a
Nonemployee Director to surrender or forfeit an Option solely because he or she
accepts an appointment as an officer or employee of the Company at any time
after election or appointment to the Board. However, during such time as a
Nonemployee Director serves as an officer or employee, he or she shall not be
eligible to receive any additional awards under this Plan.

11.      LIMITATION OF LIABILITY

         As illustrative of the limitations of liability of the Company, but not
intended to be exhaustive thereof, nothing in the Plan shall be construed to:

                  (i)      give any person any right to be granted an Option
                           other than as specifically provided by the Plan;

                  (ii)     give any person any rights whatsoever with respect to
                           Shares except as specifically provided in the Plan;

                  (iii)    limit in any way the right of the Company to
                           terminate the service of any person as a Director
                           pursuant to the Company's bylaws and articles of
                           incorporation; or nominate or appoint any person as a
                           Director.

12.      REGULATIONS AND OTHER APPROVALS; GOVERNING LAW

         12.1     This Plan and the rights of all persons claiming hereunder
shall be construed and determined in accordance with the laws of the State of
Delaware without giving effect to the

                                       8

<PAGE>

conflicts of laws principles thereof, except to the extent that such law is
preempted by federal law.

         12.2     The obligation of the Company to sell or deliver Shares with
respect to Options granted under the Plan shall be subject to all applicable
laws, rules and regulations, including all applicable federal and state
securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Board.

         12.3     The Plan is intended to comply with Rule 16b-3 promulgated
under the Exchange Act and the Board shall interpret and administer the
provisions of the Plan or any Agreement in a manner consistent therewith. Any
provisions inconsistent with such Rule shall be inoperative and shall not affect
the validity of the Plan.

         12.4     Each Option is subject to the requirement that, if at any time
the Board determines, in its discretion, that the listing, registration, or
qualification of Shares issuable pursuant to the Plan is required by any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body is necessary or desirable as a
condition of, or in connection with, the grant of an Option or the issuance of
Shares, no Options shall be granted or payment made or Shares issued, in whole
or in part, unless listing, registration, qualification, consent, or approval
has been effected or obtained free of any conditions as acceptable to the Board.

         12.5     Notwithstanding anything contained in the Plan to the
contrary, in the event that the disposition of Shares acquired pursuant to the
Plan is not covered by a then-current registration statement under the
Securities Act of 1933, as amended, and is not otherwise exempt from such
registration, such Shares shall be restricted against transfer to the extent
required by the Securities Act of 1933, as amended, and Rule 144 or other
regulations thereunder. The Board may require any individual receiving Shares
pursuant to the Plan, as a condition precedent to receipt of such Shares upon
exercise of an Option, to represent and warrant to the Company in writing that
the Shares acquired by such individual are acquired without a view to any
distribution thereof and will not be sold or transferred other than pursuant to
an effective registration thereof under said Act or pursuant to an exemption
applicable under the Securities Act of 1933, as amended, or the rules and
regulations promulgated thereunder. The certificates evidencing any of such
Shares shall be appropriately inscribed with a legend reflecting their status as
restricted securities as aforesaid.

13.      DESIGNATION OF BENEFICIARY

         Each Optionee may designate a person or persons to receive in the event
of his or her death, any Option or any amount payable pursuant thereto, to which
he or she would then be entitled. Such designation will be made upon forms
supplied by and delivered to the Company and may be revoked in writing. If an
Optionee fails effectively to designate a beneficiary, then his or her estate
will be deemed to be the beneficiary.

                         SEVERANCE PROTECTION AGREEMENT

         THIS AGREEMENT made as of the 30th day of November, 2001, by and
between Acuity Brands, Inc. (the "Company") and ______________
_______________________________ (the "Executive").

         WHEREAS, effective November 30, 2001 ("Spin-off Date"), National
Service Industries, Inc. ("NSI") is spinning off its lighting and chemicals
businesses through a tax-free distribution of the Company's stock to NSI
stockholders; and

         WHEREAS, in connection with the spin-off, Executive will become a key
management employee of the Company; and

         WHEREAS, the Board of Directors of the Company (the "Board") recognizes
that the possibility of a Change in Control (as hereinafter defined) exists and
that the threat of or the occurrence of a Change in Control can result in
significant distractions of its key management personnel because of the
uncertainties inherent in such a situation;

         WHEREAS, the Board has determined that it is essential and in the best
interest of the Company and its stockholders to retain the services of the
Executive in the event of a threat or occurrence of a Change in Control and to
ensure his continued dedication and efforts in such event without undue concern
for his personal financial and employment security; and

         WHEREAS, in order to induce the Executive to remain in the employ of
the Company, particularly in the event of a threat or the occurrence of a Change
in Control, the Company desires to enter into this Agreement with the Executive
to provide the Executive with certain benefits in the event his employment is
terminated as a result of, or in connection with, a Change in Control and to
provide the Executive with the Gross-Up Payment (as hereinafter defined) and
certain other benefits whether or not the Executive's employment is terminated.

         NOW, THEREFORE, in consideration of the respective agreements of the
parties contained herein, it is agreed as follows:

         1.       Term of Agreement.

                  (a)      This Agreement shall commence as of November 30, 2001
and shall continue in effect until November 30, 2003; provided, however, that
commencing on November 30, 2002 and on each November 30 thereafter, the term of
this Agreement shall automatically be extended for one (1) year unless either
the Company or the

<PAGE>

Executive shall have given written notice to the other at least ninety (90) days
prior to such November 30 that the term of this Agreement shall not be so
extended.

                  (b)      Notwithstanding the foregoing, (1) the term of this
Agreement shall not expire during a Threatened Change in Control Period or prior
to the expiration of 24 months after the occurrence of a Change in Control and
(2) prior to a Change in Control and other than during a Threatened Change in
Control Period, the term of this Agreement shall expire on the date the
Executive ceases to serve in the capacity he is serving on the effective date of
this Agreement, or in another capacity as an executive officer (as defined in
Rule 3b-7 under the 1934 Act), unless such cessation was at the request of a
Third Party or otherwise occurred in connection with, or in anticipation of, a
Change in Control.

                  (c)      Each place in this Agreement where a reference to the
"Company" appears that relates to the Executive's employment, termination of
employment or performing services, including the definitions of "Cause" and
"Good Reason", shall mean and include any subsidiary of the Company which is the
primary employer of the Executive. Further, in each place where this Agreement
refers to a benefit plan or program, payment of compensation, compensation
arrangement or other similar plan or program maintained by the Company, such
reference shall include any plan, program or arrangement maintained or
established by a subsidiary of the Company. Notwithstanding the foregoing, the
references in the definitions of "Change in Control," "Threatened Change in
Control Period" and similar references to changes in ownership and control of
the Company shall mean and refer to Acuity Brands, Inc., a Delaware corporation.

         2.       Definitions.

                  2.1      Cause. For purposes of this Agreement, a termination
for "Cause" is a termination evidenced by a resolution adopted in good faith by
two-thirds of the Board that the Executive (a) intentionally and continually
failed to substantially perform his duties with the Company (other than a
failure resulting from the Executive'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
Executive specifying the manner in which the Executive has failed to
substantially perform, or (b) intentionally engaged in conduct which is
demonstrably and materially injurious to the Company, monetarily or otherwise;
provided, however that no termination of the Executive's employment shall be for
Cause as set forth in clause (b) above until (x) there shall have been delivered
to the Executive a copy of a written notice setting forth that the Executive was
guilty of the conduct set forth in clause (b) and specifying the particulars
thereof in detail, and (y) the Executive shall have been provided an opportunity
to be heard by the Board (with the assistance of the Executive's counsel if the
Executive so desires). No act, nor failure to act, on the Executive's part,
shall be considered "intentional" unless he has acted, or failed to act, with an
absence of

                                       -2-
<PAGE>

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, no failure to perform by the Executive after a Notice
of Termination is given by the Executive shall constitute Cause for purposes of
this Agreement.

                  2.2      Change in Control. For purposes of this Agreement, a
"Change in Control" shall mean any of the following events:

                           (a)      The acquisition (other than from the
Company) by any "Person" (as the term person is used for purposes of Sections
13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the "1934
Act") of beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the 1934 Act) of twenty percent (20%) or more of the combined voting power
of the Company's then outstanding voting securities; or

                           (b)      The individuals who, as of December 1, 2001,
are members of the Board (the "Incumbent Board"), cease for any reason to
constitute at least two-thirds of the Board; provided, however, that if the
election, or nomination for election by the Company's stockholders, of any new
director was approved by a vote of at least two-thirds of the Incumbent Board,
such new director shall, for purposes of this Agreement, be considered as a
member of the Incumbent Board; or

                           (c)      a merger or consolidation involving the
Company if the stockholders of the Company, immediately before such merger or
consolidation do not, as a result of such merger or consolidation, own, directly
or indirectly, more than seventy percent (70%) of the combined voting power of
the then outstanding voting securities of the corporation resulting from such
merger or consolidation in substantially the same proportion as their ownership
of the combined voting power of the voting securities of the Company outstanding
immediately before such merger or consolidation; or

                           (d)      a complete liquidation or dissolution of the
Company or an agreement for 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 Section 2.2(a), 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
(hereinafter referred to as "Related Persons").

<PAGE>

                           (e)      Notwithstanding anything contained in this
Agreement to the contrary, if the Executive's employment is terminated prior to
a Change in Control and the Executive reasonably demonstrates that such
termination (1) was at the request of a Third Party (as hereinafter defined) or
(2) otherwise occurred in connection with, or in anticipation of, a Change in
Control (including, without limitation, during a Threatened Change in Control
Period), then for all purposes of this Agreement, the date of a Change in
Control shall mean the date immediately prior to the date of such termination of
the Executive's employment.

                  2.3      Confidential Information. For purpose of this
Agreement, "Confidential Information" shall mean all technical, business, and
other information relating to the business of the Company or its subsidiaries or
affiliates, including, without limitation, technical or nontechnical data,
formulae, compilations, programs, devices, methods, techniques, processes,
financial data, financial plans, product plans, and lists of actual or potential
customers or suppliers, which (i) derives economic value, actual or potential,
from not being generally known to, and not being readily ascertainable by proper
means by, other persons, and (ii) is the subject of efforts that are reasonable
under the circumstances to maintain its secrecy or confidentiality. Such
information and compilations of information shall be subject to protection under
this Agreement whether or not such information constitutes a trade secret and is
separately protectable at law or in equity as a trade secret.

                  2.4      Disability. For purposes of this Agreement,
"Disability" shall mean a physical or mental infirmity which impairs the
Executive's ability to substantially perform his duties under this Agreement for
a period of one hundred eighty (180) consecutive days.

                  2.5      (a)      Good Reason. For purposes of this Agreement,
"Good Reason" shall mean the occurrence after a Change in Control of any of the

title, position or responsibilities (including reporting responsibilities)
which, in the Executive's reasonable judgment, represents an adverse change from
his status, title, position or responsibilities as in effect immediately prior
thereto; the assignment to the Executive of any duties or responsibilities
which, in the Executive's reasonable judgment, are inconsistent with his status,
title, position or responsibilities; or any removal of the Executive from or
failure to reappoint or reelect him to any of such offices or positions, except
in connection with the termination of his employment for Disability, Cause, as a
result of his death or by the Executive other than for Good Reason;

he is entitled within five days of the date due;

                                    (3)      a failure to increase the
Executive's base salary at least annually at a percentage of base salary no less
than the average percentage increases (other than increases resulting from the
Executive's promotion) granted to the Executive during the three full years
ended prior to a Change in Control (or such lesser number of full years during
which the Executive was employed);

                                    (4)      the Company's requiring the

is not greater than such travel requirements prior to the Change in Control;

                                    (5)      the failure by the Company (A) to
continue in effect (without reduction in benefit level, and/or reward
opportunities) any compensation or employee benefit plan in which the Executive
was participating immediately prior to the Change in Control, including, but not
limited to, the plans listed on Appendix A in which Executive is participating,
unless a substitute or replacement plan has been implemented which provides
substantially identical compensation or benefits to the Executive or (B) to
provide the Executive with compensation and benefits, in the aggregate, at least
equal (in terms of benefit levels and/or reward opportunities) to those provided
for under each other compensation or employee benefit plan, program and practice
as in effect immediately prior to the Change in Control (or as in effect
following the change in Control, if greater);

                                    (6)      the insolvency or the filing (by

2.5(a)(1) through (9) which occurs prior to a Change in Control but which the

         3.       Termination of Employment.

                  3.1      If, during the term of this Agreement, the
Executive's employment with the Company shall be terminated within 24 months
following a Change in Control, the Executive shall be entitled to the following
compensation and benefits depending upon the circumstances of such termination
(in addition to any compensation and benefits provided for under any of the
Company's employee benefit plans, policies and practices):

                           (a)      If the Executive's employment with the
Company shall be terminated during such 24-month period (1) by the Company for
Cause or Disability, (2) by reason of the Executive's death, or (3) by the
Executive other than for Good Reason (as each term is defined herein), the
Company shall pay the Executive all amounts earned or accrued through the
Termination Date but not paid as of the Termination Date, including (i) base
salary, (ii) reimbursement for reasonable and necessary expenses incurred by the
Executive on behalf of the Company during the period ending on the Termination
Date, (iii) vacation pay, and (iv) sick leave (collectively, "Accrued
Compensation"). In addition to the foregoing, if the Executive's employment is
terminated by the Company for Disability or by reason of the Executive's death,
the Company shall pay to the Executive or his beneficiaries an amount equal to
the "Pro Rata Bonus" (as hereinafter defined). The "Pro Rata Bonus" is an amount
equal to the Bonus Amount (as hereinafter defined) multiplied by a fraction the
numerator of which is the number of days in such fiscal year through the
Termination Date and the denominator of which is 365. The term "Bonus Amount"
shall mean the greatest of the following: (x) most recent annual bonus paid or
payable to the Executive, or, (y) the target annual bonus payable for the fiscal
year during which the Termination Date occurs, or, if greater the fiscal year
during which a Change in Control occurred or (z) average of the annual bonuses
paid or payable during the three full fiscal years ended prior to the
Termination Date or, if greater, the three full fiscal years ended prior to the
Change in Control (or, in each case, such lesser period for which annual bonuses
were paid or payable to the Executive). Executive's entitlement to any other
compensation or benefits shall be determined in accordance with the Company's
employee benefit plans and other applicable programs and practices then in
effect.

<PAGE>

                           (b)      If the Executive's employment with the
Company shall be terminated (other than by reason of death) during such 24-month
period, (1) by the Company other than for Cause or Disability, or (2) by the
Executive for Good Reason, the Executive shall be entitled to the following:

                                    (i)      the Company shall pay the Executive
all Accrued Compensation and a Pro-Rata Bonus;

                                    (ii)     the Company shall pay the Executive
as severance pay and in lieu of any further compensation for periods subsequent
to the Termination Date, in a single payment an amount (the "Severance Amount")
in cash equal to two (2) times the sum of (A) the greater of the Executive's
base salary in effect on the Termination Date or at any time during the 90-day
period prior to the Change in Control ("Base Salary") and (B) the Bonus Amount.
Notwithstanding the foregoing, if the Executive has attained at least age 63 on
the Termination Date the Severance Amount to be paid under this Subsection (ii)
shall be the amount described in the preceding sentence multiplied by a fraction
(which in no event shall be less than one-half) the numerator of which shall be
the number of months (for this purpose any partial month shall be considered as
a whole month) remaining until the Executive's 65th birthday (but in no event
shall be less than 12) and the denominator of which shall be 24;

                                    (iii)    for a number of months equal to the
lesser of (A) 24 or (B) the number of months remaining until the Executive's
65th birthday (the "Continuation Period"), the Company shall at its expense
continue on behalf of the Executive and his dependents and beneficiaries the
life insurance, disability, medical, dental and hospitalization benefits
provided (x) to the Executive at the time the Notice of Termination is given, at
any time during the 90-day period prior to the Change in Control or at any time
thereafter, or (y) to other similarly situated executives who continue in the
employ of the Company during the Continuation Period. The coverage and benefits
(including deductibles and costs) provided in this Section 3.1(b) (iii) during
the Continuation Period shall be no less favorable to the Executive and his
dependents and beneficiaries, than the most favorable of such coverages and
benefits during any of the periods referred to in clauses (x) and (y) above. The
Company's obligation hereunder with respect to the foregoing benefits shall be
limited to the extent that the Executive obtains any such benefits pursuant to a
subsequent employer's benefit plans, in which case the Company may reduce the
coverage of any benefits it is required to provide the Executive hereunder as
long as the aggregate coverages and benefits of the combined benefit plans is no
less favorable to the Executive than the coverages and benefits required to be
provided hereunder. This Subsection (iii) shall not be interpreted so as to
limit any benefits to which the Executive or his dependents may be entitled
under any of

                                      -8-
<PAGE>

the Company's employee benefit plans, programs or practices following the
Executive's termination of employment, including without limitation, retiree
medical and life insurance benefits;

                                    (iv)     the Company shall pay in a single
payment an amount in cash equal to the excess of (A) the Supplemental Retirement
Benefit (as defined below) had (w) the Executive remained employed by the
Company for an additional two (2) complete years of credited service (or until
his 65th birthday if earlier), (x) his annual compensation during such period
been equal to his Base Salary and the Bonus Amount, (y) the Company and/or the
Business Unit made employer contributions to each defined contribution plan in
which the Executive was a participant at the Termination Date (in an amount
equal to the amount of such contribution for the plan year immediately preceding
the Termination Date) and (z) he been fully (100%) vested in his benefit under
each retirement plan in which the Executive was a participant, over (B) the lump
sum actuarial equivalent of the aggregate retirement benefit the Executive is
actually entitled to receive under such retirement plans. For purposes of this
Subsection (iv), the "Supplemental Retirement Benefit" shall mean the lump sum
actuarial equivalent of the aggregate retirement benefit the Executive would
have been entitled to receive under the Company's supplemental executive and
other retirement plans including, but not limited to, the Acuity Brands, Inc.
Supplemental Retirement Plan for Executives ("SERP"), the Acuity Brands, Inc.
401(k) Plan for Corporate Employees, and the Acuity Brands, Inc. Pension Plan
("Pension Plan"); provided, however, if the Executive has attained at least age
50 and has been employed by the Company for at least 10 years as of the
Termination Date the calculation of the Supplemental Retirement Benefit shall be
made pursuant to the early retirement provisions under the SERP and the Pension
Plan without regard to the Executive's attained age or years of credited
service. For purposes of this Subsection (iv), the "actuarial equivalent" shall
be determined in accordance with the actuarial assumptions used for the
calculation of benefits under the Pension Plan as applied prior to the
Termination Date in accordance with such plan's past practices; and

                                    (v)      (A) the restrictions on any
outstanding incentive awards (including achievement awards, restricted stock and
granted Performance Shares) granted to the Executive under the Long-Term
Incentive Plan or under any other incentive plan or arrangement shall lapse and
such incentive awards shall become one hundred percent (100%) vested (provided,
however, that Aspiration Achievement Incentive Award shall be prorated as of the
date of the Change in Control, as provided in the Aspiration Achievement
Incentive Award Agreements), all stock options and stock appreciation rights
granted to the Executive shall become immediately exercisable and shall become
100% vested, and all Performance Units granted to the Executive shall become

purchase, for cash, any shares of unrestricted stock or shares purchased upon
exercise

                                      -9-

of any options, at a price equal to the fair market value of such shares on the
date of purchase by the Company.

                           (c)      The amounts provided for in Sections 3.1(a)
and 3.1(b)(i), (ii), (iv) and (v) shall be paid within five (5) days after the

                  3.2      The severance pay and benefits provided for in
Sections 3.1(a) and 3.1(b)(i) and (ii) shall be in lieu of any other severance
pay to which the Executive may be entitled under any Company severance plan,
program or arrangement for a termination of employment covered by such
circumstances.

         4.       Notice of Termination. During a Threatened Change in Control
Period and following a Change in Control, any purported termination by the
Company or by the Executive shall be communicated by written Notice of
Termination to the other. For purposes of this Agreement, a "Notice of
Termination" shall mean a notice which indicates the specific termination

during such period of at least 30 days; and

                  (b)      If the Executive's employment is terminated for Good

         6.       Excise Tax Payments.

                  (a)      Notwithstanding anything contained in this Agreement
to the contrary and without regard to whether the Executive's employment with
the Company has terminated, in the event that any payment or benefit (within the
meaning of Section 280G(b) (2) of the Internal Revenue Code of 1986, as amended
(the "Code"), to the Executive or for his benefit, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise in connection with, or arising out of, his employment with the Company
or a change in ownership or effective control of the Company or of a substantial
portion of its assets (a "Payment" or "Payments"), would be subject to the
excise tax imposed by Section 4999 of the Code or any interest or penalties are
incurred by the Executive with respect to such excise tax (such excise tax,
together with any such interest and penalties, are hereinafter collectively
referred to as the "Excise Tax"), then the Executive shall be entitled to
receive an additional payment (a "Gross-Up Payment") in an amount such that
after payment by the Executive of all taxes (including any interest or penalties
imposed with respect to such taxes and the Excise Tax), including any Excise
Tax, imposed upon the Gross-Up Payment, the Executive retains an amount of the
Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

                  (b)      An initial determination as to whether a Gross-Up
Payment is required pursuant to this Section 6 and the amount of such Gross-Up
Payment shall be made by an accounting firm selected by the Company and
reasonably acceptable to the Executive which is designated one of the five
largest accounting firms in the United States (the "Accounting Firm"). The
Accounting Firm shall provide its determination (the "Determination"), together
with detailed supporting calculations and documentation to the Company and the
Executive within five days of the Termination Date if applicable, or such other
time as requested by the Company or by the Executive (provided the Executive
reasonably believes that any of the Payments may be subject to the Excise Tax)
and if the Accounting Firm determines that no Excise Tax is payable by the
Executive with respect to a Payment or Payments, it shall furnish the Executive
with an opinion reasonably acceptable to the Executive that no Excise Tax will
be imposed with respect to any such Payment or Payments. Within five days of the
delivery of the Determination to the Executive, the Executive shall have the
right to dispute the Determination (the "Dispute). The Gross-Up Payment, if any,
as determined pursuant to this Section 6(b) shall be paid by the Company to the
Executive within five days of the receipt of the Accounting Firm's determination
or, subject to Executive's approval, all or a portion of the Gross-Up Payment
may be paid directly to the appropriate tax authorities. The existence of the
Dispute shall not in any way affect the right of the Executive to receive the
Gross-Up Payment in accordance with the Determination. If there is no Dispute,
the Determination shall be binding, final and conclusive upon the Company and
the Executive subject to the application of Section 6(c).

                  (c)      As a result of the uncertainty in the application of
Sections 4999 and 280G of the Code, it is possible that a Gross-Up Payment (or a
portion thereof) will be paid which should not have been paid (an "Excess
Payment") or a Gross-Up Payment (or a portion thereof) which should have been
paid will not have been paid (an "Underpayment"). An Underpayment shall be
deemed to have occurred (1) upon notice (formal or informal) to the Executive
from any governmental taxing authority that the tax liability of the Executive
(whether in respect of the then current taxable year of the Executive or in
respect of any prior taxable year of the Executive) may be increased by reason
of the imposition of the Excise Tax on a Payment or Payments with respect to
which the Company has failed to make a sufficient Gross-Up Payment, (2) upon a
determination by a court, (3) by reason of a determination by the Company (which
shall include the position taken by the Company, or together with its
consolidated group, on its federal income tax return) or (4) upon the resolution
to the satisfaction of the Executive of the Dispute. If an Underpayment occurs,
the Executive shall promptly notify the Company and the Company shall pay to the
Executive at least five days prior to the date on which the applicable
government taxing authority has requested payment, an additional Gross-Up
Payment equal to the amount of the Underpayment plus any interest and penalties
(other than interest and penalties imposed by reason of a failure to file timely
a tax return or pay taxes shown due on a return) imposed on the Underpayment. An
Excess Payment shall be deemed to have occurred upon a "Final Determination" (as
hereinafter defined) that the Excise Tax shall not be imposed upon a Payment or
Payments with respect to which the Executive had previously received a Gross-Up
Payment. A Final Determination shall be deemed to have occurred when the
Executive has received from the applicable government taxing authority a refund
of taxes or other reduction in his tax liability by reason of the Excess Payment
and upon either (i) the date a determination is made by, or an agreement is
entered into with, the applicable governmental taxable authority which finally
and conclusively binds the Executive and such taxing authority, or in the event
that a claim is brought before a court of competent jurisdiction, the date upon
which a final determination has been made by such court and either all appeals
have been taken and finally resolved or the time for all appeals has expired or
(ii) the statute of limitations with respect to the Executive's applicable tax
return has expired. If an Excess Payment is determined to have been made, the
amount of the Excess Payment shall be treated as a loan by the Company to the
Executive and the Executive shall pay to the Company on demand (but not less
than 10 days after the determination of such Excess Payment) the amount of the
Excess Payment plus interest at an annual rate equal to the rate provided for in
Section 1274(b)(2)(B) of the Code from the date the Gross-Up Payment (to which
the Excess Payment relates) was paid to the Executive until the date of
repayment to the Company.

                  (d)      Notwithstanding anything contained in this Agreement
to the contrary, in the event that, according to the Determination, an Excise
Tax will be imposed on any Payment or Payments, the Company shall pay to the
applicable

                                      -12-
<PAGE>

government taxing authorities as Excise Tax withholding, the amount of the
Excise Tax that the Company has actually withheld from the Payment or Payments.

         7.       Unauthorized Disclosure. During the period that the Executive
is actively employed by the Company or Business Unit, the Executive shall not
make any Unauthorized Disclosure. For purposes of this Agreement, "Unauthorized
Disclosure" shall mean disclosure by the Executive without the consent of the
Board (other than pursuant to a court order) to any person, other than an
employee or director of the Company or a person to whom disclosure is reasonably
necessary or appropriate in connection with the performance by the Executive of
his duties as an executive of the Company or as may be legally required, of any
material Confidential Information obtained by the Executive while in the employ
of the Company (including any material Confidential Information with respect to
any of the Company's customers or methods of distribution) the disclosure of
which is demonstrably and materially injurious to the Company; provided,
however, that such term shall not include the use or disclosure by the
Executive, without consent, of any information known generally to the public
(other than as a result of disclosure by him in violation of this Section 7) or
any information not otherwise considered confidential and material by a
reasonable person engaged in the same business as that conducted by the Company;
provided further, however, that any breach of this Section 7 shall in no event
subject the Executive to damages (including costs, fees and expenses incurred by
the Company or the Business Unit) in excess of $10,000 in the aggregate.

         8.       Non-Compete. During the period that the Executive is actively
employed by the Company or Business Unit, the Executive shall not directly or
indirectly, own, manage, operate, control, consult with, or be connected as an
officer, employee, agent, partner, director or consultant with, or have any
financial interest in, or assist anyone in the conduct of, any business which
directly competes with the businesses of the Company in the State of Georgia.
Notwithstanding the foregoing, the Executive shall not be in violation of the
preceding sentence due to ownership (directly or indirectly) by the Executive of
not more than five percent (5%) of the issued and outstanding class of
securities of a corporation whose securities are publicly traded.

         9.       Successors; Binding Agreement.

                  (a)      This Agreement shall be binding upon and shall inure
to the benefit of the Company, its successors and assigns and the Company shall
require any successor or assign to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform it if no such succession or assignment had taken place. The
term "the Company" as used herein shall include such successors and assigns. The
term "successors and assigns" as used herein shall mean a corporation or other
entity acquiring all or substantially all the assets and business of the Company
(including this Agreement) whether by operation of law or otherwise.

                  (b)      Neither this Agreement nor any right or interest
hereunder shall be assignable or transferable by the Executive, his
beneficiaries or legal representatives, except by will or by the laws of descent
and distribution. This Agreement shall inure to the benefit of and be
enforceable by the Executive's legal personal representative.

         10.      Fees and Expenses. The Company shall pay all legal fees and
related expenses (including the costs of experts, evidence and counsel) incurred
by the Executive as they become due as a result of (a) the Executive's
termination of employment (including all such fees and expenses, if any,
incurred in contesting or disputing any such termination of employment), (b) the
Executive seeking to obtain or enforce any right or benefit provided by this
Agreement or by any other plan or arrangement maintained by the Company under
which the Executive is or may be entitled to receive benefits, including,
without limitation, the plans listed on Appendix A in which Executive is
participating, or (c) the Executive's hearing before the Board as contemplated
in Section 2.1 of this Agreement; provided, however, that the circumstances
which result in the Executive incurring the fees and related expense set forth
in clauses (a) and (b) (other than as a result of the Executive's termination of
employment under circumstances described in Section 2.2(e)) occurred on or after
a Change in Control.

         11.      Notice. For the purposes of this Agreement, notices and all
other communications provided for in the Agreement (including the Notice of
Termination) shall be in writing and shall be deemed to have been duly given
when personally delivered or sent by certified mail, return receipt requested,
postage prepaid, addressed to the respective addresses last given by each party
to the other, provided that all notices to the Company shall be directed to the
attention of the Board with a copy to the Secretary of the Company. All notices
and communications shall be deemed to have been received on the date of delivery
thereof or on the third business day after the mailing thereof, except that
notice of change of address shall be effective only upon receipt.

         12.      Non-Exclusivity of Rights. Nothing in this Agreement shall
prevent or limit the Executive's continuing or future participation in any
benefit, bonus, incentive or other plan or program provided by the Company or
any of its subsidiaries and for which the Executive may qualify, nor shall
anything herein limit or reduce such rights as the Executive may have under any
other agreements with the Company or any of its subsidiaries. Amounts which are
vested benefits or which the Executive is otherwise entitled to receive under
any plan or program of the Company or any of its subsidiaries shall be payable
in accordance with such plan or program, except as explicitly modified by this
Agreement.

         13.      Settlement of Claims. The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim, recoupment, defense or other right which
the Company may have against the Executive or others.

         14.      Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and the Company. No waiver by either
party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. No agreement or
representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by either party which are not expressly set
forth in this Agreement.
