REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Plan Administrator of
Lithonia Lighting Profit Sharing and 
Retirement Plan for Salaried Employees:


We have audited the accompanying  statement of net assets available for benefits
of LITHONIA  LIGHTING PROFIT SHARING AND RETIREMENT PLAN FOR SALARIED  EMPLOYEES
as of  December 31,  1994 and 1993 and the related  statements of changes in net
assets  available  for  benefits  for the year ended  December 31,  1994 and the
four-month period ended  December 31,  1993. These financial  statements are the
responsibility  of the Plan's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the net assets  available  for  benefits  of  Lithonia
Lighting  Profit  Sharing  and  Retirement  Plan for  Salaried  Employees  as of
December 31,  1994 and 1993 and the changes in net assets available for benefits
for  the  year  ended   December 31,   1994  and  the  four-month  period  ended
December 31, 1993 in conformity with generally accepted accounting principles.

Our audits  were  performed  for the  purpose of forming an opinion on the basic
financial  statements taken as a whole. The Fund information in the statement of
changes in net assets  available  for benefits is presented  for the purposes of
additional  analysis rather than to present the changes in net assets available
for  benefits  of each fund.  The Fund  information  has been  subjected  to the
auditing  procedures  applied in the audits of the basic  financial  statements,
and, in our opinion,  are fairly stated in all material  respects in relation to
the basic financial statements taken as a whole.

LITHONIA LIGHTING PROFIT SHARING AND RETIREMENT PLAN



1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Basis of Accounting

The accounts of the Lithonia  Lighting  Profit Sharing and  Retirement  Plan for
Salaried  Employees (the "Plan") of Lithonia  Lighting Company (LLC), a division
of National Service Industries, Inc. (NSI), are maintained by the trustee on the
cash  basis of  accounting.  The  accompanying  financial  statements  have been
prepared  using the accrual  method of accounting by  application  of memorandum
entries.

Investment in NSI Defined Contribution Master Trust Fund

Beginning  September 1, 1993, a portion of the Plan's  assets were invested in a
Defined Contribution Master Trust Fund (DC Master Trust).  Investments of the DC
Master Trust are  reflected at market values  determined  by the custodian  from
publicly  stated price  information.  These  investments  are subject to certain
administrative  guidelines  and  limitations as to type and amount of securities
held.  Certain  fund assets are  allocated  to selected  independent  investment
managers  to invest  under the  general DC Master  Trust  guidelines.  Effective
January 1, 1994,  participants  of the Plan can direct the  investment  of their
accounts into the various options discussed in Note 4. Prior to January 1, 1994,
the  assets  of the Plan  were  invested  at the  discretion  of the  Investment
Committee.

Summarized  financial  information  of the NSI DC Master  Trust is  presented as
follows  for  the  year  ended  December 31,   1994  and  for  the  period  from
September 1, 1993 through December 31, 1993:

Investment in NSI Common Stock

As of December 31, 1994, approximately 1% of the Plan's net assets were invested
in common stock of NSI, a party-in-interest. The Plan's investment in NSI common
stock was reflected at market value in the accompanying financial statements.

Loans to Participants

The  Plan  permits  loans  to  participants  up to  the  lower  of  50%  of  the
participant's  vested account balance or $50,000.  Participants  have up to five
years to pay back the principal and interest unless the loan is for the purchase
of a primary  residence,  in which case the repayment period will be established
at the time the loan is approved.  Loan processing fees are charged  directly to
the participants' account.



Page 8

Tax Status

The Plan has received a favorable determination letter from the Internal Revenue
Service dated  September 5,  1986, and is qualified  under the Internal  Revenue
Code (the "Code") as exempt from federal income taxes. The Plan has been amended
since  receiving  the  determination  letter.  However,  the plan  administrator
believes that the Plan is currently designed and is being operated in compliance
with the applicable requirements of the Code. Therefore,  the plan administrator
believes that the Plan was  qualified and that the related trust was  tax-exempt
as of December 31, 1994.


2.  TRUST AGREEMENT

Under a trust agreement  dated  September 1, 1993, as amended,  Wachovia Bank of
Georgia, N.A. was appointed trustee of the NSI Defined Contribution Plans Master
Trust (which includes the DC Master Trust,  Loans to Participants and NSI Common
Stock   discussed  in  Note  1).   Certain   officers  of  NSI  were   appointed
administrators of the Plan's assets together with the income derived therefrom.

Prior to  September 1,  1993,  the assets of the Plan were  included  in the NSI
General  Retirement  Trust (GRT).  Under a trust agreement dated March 1,  1978,
certain   officers  of  NSI  were   appointed   trustee  of  the  GRT  and  were
administrators  of the  Plan's  assets  and  Wachovia  Bank of  Georgia  was the
custodian.


3.  PLAN DESCRIPTION

The  following  brief  description  of the Plan is  provided  for  informational
purposes only. Participants should refer to the Plan agreement for more complete
information.

The Plan incorporates  requirements of Section 401(a) and 501(a) of the Internal
Revenue  Code of 1986 and  ERISA as  amended  from  time to time.  The Plan is a
voluntary, defined contribution plan covering all full-time, non-union, salaried
employees of the Company with six or more months of service.  Contributions  are
made by the participants and the Company. Participants contribute between 1% and
15% of before-tax  compensation  but not to exceed $8,994 (or such larger amount
as may be determined by the  Secretary of Treasury) for any  participant  in any
calendar year. Prior to September 1, 1993 the maximum  percentage was limited to
10%. Participants are 100% vested in their voluntary contributions.  The Company
contributes an amount equal to 50% of each participant's  Elective  Contribution
up to 6% of compensation for each Plan year.  Non-vested employer  contributions
are forfeited upon withdrawal or termination,  as defined, from the Plan and are
added to the employer contribution for allocation to remaining participants. For
any Plan year in which Net Profits,  as defined,  equal or exceed $6,000,000 the
Employer  shall  contribute  the greater of the 50%  matching  contribution,  as
discussed above, or 2% of the Net Profit for the Plan year.  Vesting of employer
contributions  occurs on an increasing  scale ranging from 10% after one year of
service, as defined, to 100% vesting after seven years of service.  All expenses
of the Plan were paid by the Company during 1994 and 1993.



Page 9

During  December  1993,  the Plan was amended and restated to allow  participant
directed investments effective January 1,  1994. In addition,  the Plan year end
was changed from  August 31 to  December 31.  The Plan, as amended and restated,
does  not  permit  employer  contributions  in  excess  of 5%  of  participants'
compensation during the short plan year.

Although the Company  intends for the Plan to be  permanent,  the Plan  provides
that the Company has the right to discontinue  contributions or to terminate the
Plan at any time. In the event of termination,  the participants are vested with
the amounts allocated to their respective accounts;  however, the accounts shall
continue to be held by the trustee until such time as the participants terminate
their  employment or otherwise become entitled to such vested benefits under the
provisions of the Plan.
