                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        National Service Industries, Inc.


(In thousands, except share and per-share data)

Note 1:  Summary of Accounting Policies

Description of Business
The company operates in four business segments - lighting equipment,  chemicals,
textile  rental,  and  envelopes - each of which is a leading  competitor in its
respective  markets.  The  lighting  equipment  segment  produces  a variety  of
fluorescent  and  non-fluorescent  fixtures  for markets  throughout  the United
States, Canada, Mexico, and overseas. The chemical segment produces maintenance,
sanitation,  and water  treatment  products for customers  throughout the United
States,  Canada, Puerto Rico, Western Europe, and Australia.  The textile rental
segment  provides linens and dust control products to healthcare,  lodging,  and
dining customer  segments in the United States.  The envelope  segment  produces
business and specialty envelopes in the United States.

Revenue Recognition and Product Warranty
The  company  records  revenues  as  products  are  shipped or as  services  are
rendered. A provision for estimated returns,  allowances,  and warranty costs is
recorded when products are shipped.

Principles of Consolidation
The consolidated  financial  statements  include the accounts of the company and
all subsidiaries after elimination of significant intercompany  transactions and
accounts.

Use of Estimates
The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the  reported  amounts  of assets  and  liabilities,  the  disclosure  of
contingent assets and liabilities at the date of the financial  statements,  and
the  reported  amounts of revenues  and expenses  during the  reporting  period.
Actual results could differ from those estimates.

Cash, Cash Equivalents, and Short-Term Investments
Cash in excess of daily requirements is invested in time deposits and marketable
securities  and is included in the  accompanying  balance sheet at market value.
The company considers time deposits and marketable  securities purchased with an
original  maturity of three months or less to be cash  equivalents.  Investments
purchased  with a maturity  of more than  three  months and less than a year are
considered  short-term  investments.  There were no  short-term  investments  at
August 31, 1999 and 1998.


Concentrations of Credit Risk
Concentrations of credit risk with respect to receivables are limited due to the
wide variety of customers and markets using the company's products and services,
as well as their dispersion across many different geographic areas. As a result,
as of  August  31,  1999,  the  company  does not  consider  itself  to have any
significant concentrations of credit risk.

Inventories and Linens in Service
Inventories are valued at the lower of cost (on a first-in,  first-out basis) or
market and consisted of the following at August 31, 1999 and 1998:



                                                         1999                1998
- --------------------------------------------------  ------------       --------------
                                                                     
Raw materials and supplies                            $  99,249            $  78,730
Work in progress                                         16,718               10,725
Finished goods                                          102,224              108,495
- --------------------------------------------------  ------------       --------------
                                                      $ 218,191            $ 197,950
                                                    ------------       --------------


      Linens in  service  are  recorded  at cost and are  amortized  over  their
estimated useful lives of 15 to 50 months.

Goodwill and Other Intangibles
Goodwill of $3,460 was recognized in connection with a 1969  acquisition and is
not being amortized.  Remaining  amounts of goodwill  ($385,380 in 1999 and
$71,059 in 1998) and other intangible assets are being amortized on a
straight-line basis over various periods ranging from 2 to 40 years.
      The company  periodically  evaluates whether events and circumstances have
occurred that may warrant revision of the estimated useful lives of goodwill and
other long-lived  assets or whether the remaining  balance of goodwill should be
evaluated  for  possible  impairment.  The  company  uses an estimate of related
undiscounted  cash flows over the  remaining  life of the  goodwill in measuring
whether the goodwill is  recoverable.  During  fiscal  1997,  goodwill and other
intangibles  of  $8,800  were  written  off  due to the  impairment  of  related
long-lived assets (See Note 6: Restructuring Expense and Asset Impairments).

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                        National Service Industries, Inc.


Depreciation
For financial  reporting purposes,  depreciation is determined  principally on a
straight-line  basis using estimated  useful lives of plant and equipment (20 to
40 years for  buildings and 3 to 16 years for  machinery  and  equipment)  while
accelerated  depreciation  methods are used for income tax  purposes.  Leasehold
improvements  are amortized over the life of the lease or the useful life of the
improvement, whichever is shorter.

Research and Development
Research and development costs are expensed as incurred.  Research and
development expenses amounted to $8,482, $13,577, and $8,561 during 1999, 1998,
and 1997, respectively.

Foreign Currency Translation
The  functional  currency  for the  company's  foreign  operations  is the local
currency.  The translation of foreign  currencies into U.S. dollars is performed
for balance sheet  accounts  using exchange rates in effect at the balance sheet
date and for revenue and expense accounts using a weighted average exchange rate
during  the  period.  The  gains or  losses,  net of  applicable  income  taxes,
resulting from the translation are included in "Accumulated Other  Comprehensive
Income Items" in the  Consolidated  Statements of  Stockholders'  Equity and are
excluded from net income.
      Gains or losses resulting from foreign currency  transactions are included
in "Other (income) expense,  net" in the Consolidated Statements of Income and
were insignificant in 1999, 1998, and 1997.

Postretirement Healthcare and Life Insurance Benefits
The  company's   retiree   medical  plans  are  financed   entirely  by  retiree
contributions;  therefore, the company has no liability in connection with them.
Several programs provide limited retiree life insurance benefits.  The liability
for these plans is not material.

Postemployment Benefits
Statement  of  Financial  Accounting  Standards  ("SFAS")  No. 112,  "Employers'
Accounting for Postemployment  Benefits,"  requires the accrual of the estimated
cost of benefits  provided by an employer to former or inactive  employees after
employment but before retirement.  The company's accrual, which is not material,
relates  primarily to severance  agreements and the liability for life insurance
coverage for certain eligible employees.

Interest Expense, Net
Interest expense,  net, is comprised  primarily of interest expense on long-term
debt,  credit  facility  borrowings,   commercial  paper,  and  line  of  credit
borrowings offset by interest income on cash, cash  equivalents,  and short-term
investments.

Other (Income) Expense, Net
Other  (income)  expense,   net,  is  comprised  primarily  of  amortization  of
intangible assets net of gains resulting from the sale of fixed assets.

Accounting Standards Adopted
During 1999, the company adopted SFAS No. 130, "Reporting Comprehensive Income,"
which  requires the reporting of a measure of all changes in equity of an entity
that result from  recognized  transactions  and other economic events other than
transactions with owners in their capacity as owners.  The disclosures  required
by SFAS No. 130 are presented in the  Consolidated  Statements of  Stockholders'
Equity.
      The company adopted SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related  Information," which requires the reporting of financial
information on the basis that it is used  internally for evaluating  segment
performance and the allocation of resources to segments.  The  disclosures
required by SFAS No. 131 are presented in Note 10: Business Segment Information.
      The company adopted SFAS No. 132, "Employers'  Disclosures about Pensions
and Other Postretirement  Benefits." SFAS No. 132 amends SFAS Nos. 87, 88, and
106 by standardizing the disclosure  requirements  for pensions and other
postretirement  benefits,  requiring additional  information on changes in
benefit  obligations and fair values of plan assets, and eliminating certain
other disclosures.  The disclosures required by SFAS No. 132 are presented in
Note 2: Pension and Profit Sharing Plans.
      The company also adopted  Statement of Position 98-1,  "Accounting for the
Costs of Computer  Software  Developed or Obtained for Internal  Use," issued by
the American Institute of Certified Public Accountants.  This statement requires
the  capitalization of certain internal use software costs. The adoption of this
statement  did  not  have  a  material  impact  on  the  consolidated  financial
statements or results of operations.

Accounting Standards Yet to be Adopted
SFAS No. 133,  "Accounting for Derivative  Instruments and Hedging  Activities,"
was issued in June 1998 and is effective for all fiscal quarters of fiscal years
beginning  after  June  15,  2000.  However,  the  company  does  not  currently
participate  in any  significant  hedging  activities,  nor does it utilize  any
significant derivative financial instruments.

Reclassifications
Certain  prior period  amounts in the financial  statements  and notes have been
reclassified to conform with the 1999 presentation.




                                                                        Page 109

Note 2:  Pension and Profit Sharing Plans

The company has several  pension plans covering  hourly and salaried  employees.
Benefits  paid under  these plans are based  generally  on  employees'  years of
service and/or  compensation  during the final years of employment.  The company
makes  annual  contributions  to the plans to the extent  indicated by actuarial
valuations.  Plan  assets are  invested  primarily  in equity  and fixed  income
securities.
     The following  tables reflect the status of the company's  pension plans at
August 31, 1999 and 1998:


                                                             1999         1998

      During 1999, the discount rate used to determine the projected  benefit
obligation was increased to 7.5 percent to more closely  approximate  rates on
high-quality,  long-term obligations.

      The  company  also has  profit  sharing  and  401(k)  plans to which  both
employees and the company  contribute.  At August 31, 1999, assets of the 401(k)
plans  included  shares of the  company's  common  stock with a market  value of
approximately  $11,479.  The  company's  cost of these plans was $4,521 in 1999,
$4,292 in 1998, and $5,020 in 1997.

Note 3:  Long-Term Debt and Lines of Credit

Long-term debt at August 31, 1999 and 1998, consisted of the following:

     The annual  principal  payments of long-term debt for the five-year  period
ending August 31, 2004 are: 2000 - $368;  2001 - $207;  2002 - $107; 2003 - $95;
2004 - $103.
     In 1996, the company negotiated a $250,000 multi-currency  committed credit
facility (the "Credit Facility") with ten domestic and international  banks. The
Credit  Facility  has a term of five  years,  expiring  in  July  2001,  with no
provision  for  a  reduction  in  commitments.   The  Credit  Facility  contains
restrictions  on the  incurrence of  indebtedness  by  subsidiaries,  as well as
financial  and other  covenants,  including the  restriction  that the company's
ratio of total debt to capitalization may not exceed 60 percent at any time.
      During  the fourth  quarter  of 1998,  the  company  filed a  registration
statement (the "shelf registration"),  which became effective September 8, 1998,
with the  Securities  and Exchange  Commission to allow the company to offer for
sale,  from time to time, up to $400,000 of unsecured  senior debt securities or
unsecured senior subordinated debt securities (the "Debt Securities") consisting
of notes,  debentures,  or other  evidence of  indebtedness,  of which  $240,000
remains  available at August 31, 1999.  The Debt  Securities  may be convertible
into or  exchangeable  for shares of the company's  common stock,  shares of its
preferred stock, or other Debt Securities. The Debt Securities may be offered as
a single series or as two or more separate  series in amounts,  at prices and on
terms to be determined at the time of the offering.  The Debt  Securities may be
sold to or through one or more agents designated from time to time.
      In January 1999, the company issued  $160,000 in ten-year  publicly traded
notes  bearing a coupon rate of 6.0 percent.  Proceeds  from this  issuance were
used for the repayment of $80,000 in borrowings  under the Credit  Facility,  of
which  $52,000 was  outstanding  under the  domestic  line of credit,  discussed
below, at August 31, 1998. The remainder was used for general corporate purposes
including working capital requirements, capital expenditures,  acquisitions, and
share  repurchases.  In July  1999,  the  company  entered  into  an  additional
$250,000,  364-day  committed credit facility (the "Revolving  Credit Facility")
expiring in July 2000. The combined  $500,000 under the Credit  Facility and the
Revolving Credit Facility support the company's commercial paper program,  which
was initiated in July 1999. Interest rates under the credit facilities are based
on the LIBOR rate or other rates, at the company's  option.  The company pays an
annual fee on the  commitments  based on the company's  debt rating and leverage
ratio. No amounts were outstanding  under either facility at August 31, 1999 and
1998.
      At August  31,  1999,  the  company  had  $352,265  outstanding  under its
commercial  paper program,  of which $249,726 was classified as long-term as the
company intends to refinance this amount through  long-term debt  instruments or
availability  under  the  Credit  Facility  which  matures  in 2001.  Short-term
commercial paper of $102,539 had an average interest rate of 5.8 percent.
      At August 31, 1999, the company had complimentary lines of credit totaling
$125,672 for general  operating  purposes,  of which  $25,672 is  designated  as
multi-currency.   At  August  31,  1999,  $76,890  in  letters  of  credit  were
outstanding,  primarily  under the  domestic  line of credit.  The  company  had
$10,864 of foreign currency  short-term bank borrowings under the multi-currency
line of credit at a weighted-average  interest rate of 3.8 percent at August 31,
1999.
      Except for the $160,000 notes, long-term debt recorded in the accompanying
Consolidated Balance Sheets approximates fair value based on the borrowing rates
currently available to the company for bank loans with similar terms and average
maturities. The fair value of the $160,000 notes, based on quoted market prices,
was approximately $145,424 at August 31, 1999.

Note 4:  Common Stock and Related Matters

Shares Authorized
In January 1999,  the  stockholders  approved an amendment to the  corporation's
Restated  Certificate of Incorporation to increase the corporation's  authorized
shares of common stock from  80,000,000 to  120,000,000.  The additional  shares
will be available for potential  acquisitions,  stock dividends and splits,  and
other purposes  determined by the board of directors to be in the best interests
of the corporation.

Shareholder Rights Plan
The  company has a  shareholder  rights  plan under  which one  preferred  stock
purchase right is presently  attached to and trades with each outstanding  share
of the company's common stock. The plan, which was to have expired May 19, 1998,
was amended and extended to May 19, 2008.

                                                                        Page 111
                                                                      Exhibit 13


             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                        National Service Industries, Inc.


     The rights become  exercisable and transferable apart from the common stock
(a) on the date that a person or group  announces  that  they have  acquired  15
percent or more of the company's  common stock or (b) ten days after a person or
group makes an  unsolicited  offer to acquire  beneficial  ownership  of, or the
right to obtain  beneficial  ownership  of, 15 percent or more of the  company's
common stock  (unless such date is extended by the board of directors) or (c) 20
business  days  before the date on which a business  combination  is  reasonably
expected to be consummated  involving a person who, if the business  combination
is consummated,  has or would acquire  beneficial  ownership of, or the right to
obtain beneficial ownership of, 15 percent or more of the company's common stock
and that person has directly or  indirectly  nominated a director of the company
at the time the business combination is considered. The rights are not triggered
if the board of directors is notified  that  reaching the trigger  threshold was
inadvertent  and  divestiture  of  sufficient  stock is  thereafter  made.  Once
exercisable, each right entitles the holder to purchase one one-thousandth share
of Series A Participating  Preferred Stock at an exercise price of $160, subject
to adjustment to prevent  dilution.  The rights have no voting power and,  until
exercised,  no dilutive effect on net income per common share. The rights expire
on May 19, 2008, and are redeemable under certain circumstances.
      If a person  acquires 15 percent  ownership,  except in an offer  approved
under the plan by a majority of the nonemployee directors,  each right not owned
by the acquirer or related  parties will entitle its holder to purchase,  at the
right's exercise price, common stock or common stock equivalents having a market
value  immediately  prior to the  triggering of the right of twice that exercise
price.  In  addition,  after an acquirer  obtains 15 percent  ownership,  if the
company is involved in certain mergers,  business combinations,  or asset sales,
each right not owned by the acquirer or related  persons will entitle its holder
to purchase,  at the right's exercise price, shares of common stock of the other
party  to the  transaction  having  a  market  value  immediately  prior  to the
triggering of the right of twice that exercise price.

Preferred Stock
The company has 1,000,000 shares of preferred stock authorized, 500,000 of which
have been reserved for issuance under the shareholder  rights plan. No shares of
preferred stock had been issued at August 31, 1999 and 1998.

Earnings per Share
During fiscal 1998, the company adopted SFAS No. 128, "Earnings per Share." SFAS
No. 128 superseded Accounting Principles Board ("APB") Opinion No. 15, "Earnings
per Share," and  promulgated  new accounting  standards for the  computation and
manner of presentation of the company's  earnings per share. Upon adoption,  the
company was required to restate previously  reported annual and interim earnings
per share in  accordance  with the  provisions  of SFAS No. 128. The adoption of
SFAS No.  128 did not have a  material  impact on the  computation  or manner of
presentation of the company's  earnings per share as previously  presented under
APB 15.
      The  following  table  represents  a  reconciliation  of basic and diluted
earnings per share at August 31:

Stock-Based Compensation
In 1990,  stockholders approved the National Service Industries,  Inc. Long-Term
Incentive  Program for the benefit of officers  and other key  employees. There
were 1,750,000 treasury shares reserved for issuance under the program.
     In 1997,  stockholders  approved  the  National  Service  Industries,  Inc.
Long-Term  Achievement  Incentive Plan for the benefit of officers and other key
employees. There were 1,750,000 treasury shares reserved for issuance under that
plan.
     Aspiration Achievement Incentive Awards were granted annually beginning in
September 1996 under the Long-Term  Achievement  Incentive  Plan.  Shares may be
earned and issued to participants based on a level of achievement of performance
over three year performance  cycles.  In some cases, the shares may be exchanged
for stock options.  Amounts charged to compensation  expense for 1999, 1998, and
1997 were $9,244, $7,203, and $3,841, respectively,  of which approximately half
related to the stock portion of the award. No shares were issued under the award
as of August 31, 1999.
     Generally,  the stock options  granted  under both the  incentive  programs
become exercisable in four equal annual installments beginning one year from the
date of the grant.
     In January 1993,  stockholders  approved the National  Service  Industries,
Inc. 1992 Nonemployee Directors' Stock Option Plan, under which 100,000 treasury
shares were  reserved for issuance.  The stock  options  granted under that plan
become exercisable one year from the date of the grant.
     Under all stock option plans, the options expire ten years from the date of
the grant  and have an  exercise  price  equal to the fair  market  value of the
company's  stock on the date of the grant.  At August 31,  shares  available for
issuance under all plans were 694,279 in 1999,  1,236,574 in 1998, and 1,732,574
in 1997.

      During fiscal 1997, the company adopted the disclosure-only  provisions of

compensation  cost for the company's stock option plans been determined based on
the fair value at the grant date for awards in fiscal years 1999, 1998, and 1997
consistent  with the  provisions  of SFAS No. 123, the  company's net income and
earnings per share would have been reduced to the following pro forma amounts:

      The fair value of each option  grant is estimated on the date of the grant

fair value of options was $13.70,  $12.23,  and $9.69 for 1999,  1998, and 1997,
respectively.  The following weighted average  assumptions were used to estimate

Employee Stock Purchase Plan
In 1998,  stockholders  approved the National Service Industries,  Inc. Employee
Stock  Purchase  Plan for the  benefit of  eligible  employees.  Under the plan,
employees may purchase, through payroll deduction, the company's common stock at
a 15 percent discount. Shares are purchased quarterly at 85 percent of the lower
of the fair market value of the company's common stock on the first business day
of the quarterly  plan period or on the last business day of the quarterly  plan
period.  There were 1,500,000  treasury  shares  reserved for purchase under the
plan,  of which  1,372,881  shares  remain  available for purchase at August 31,
1999.

Note 5:  Commitments and Contingencies

Self-Insurance
It is the company's policy to self insure for certain insurable risks consisting
primarily of physical loss to property;  business  interruptions  resulting from
such loss; and workers' compensation, comprehensive general, and auto liability.
Insurance coverage is obtained for catastrophic  property and casualty exposures
as well as those risks  required to be insured by law or  contract.  Based on an
independent actuary's estimate of the aggregate liability for claims incurred, a
provision  for claims  under the  self-insured  program is recorded  and revised
annually.


      The major components of the self-insurance liability at August 31 were as
follows:
                                                  1999        1998         1997

                        National Service Industries, Inc.

Leases
The company  leases certain of its buildings and equipment  under  noncancelable
lease agreements.  Minimum lease payments under  noncancelable  leases for years
subsequent to August 31, 1999, are as follows:  2000 - $13,902;  2001 - $11,542;
2002 - $8,260; 2003 - $6,170; 2004 - $4,624; after 2004 - $6,686.
      Total rent  expense was $16,536 in 1999,  $12,237 in 1998,  and $11,327 in
1997.

Collective Bargaining Agreements
Approximately  55  percent  of the  company's  total  work  force is  covered by
collective bargaining agreements.  Collective bargaining agreements representing
13 percent of the company's total work force will expire within one year.

Litigation
The company is involved in various legal matters primarily arising in the normal
course of business.  In the opinion of  management,  the company's  liability in
these matters will not have a material adverse effect on its financial condition
or results of operations.

Environmental Matters
The company's operations,  as well as similar operations of other companies, are
subject  to  comprehensive  laws and  regulations  relating  to the  generation,
storage,  handling,  transportation,  and disposal of hazardous  substances  and
solid and hazardous wastes and to the remediation of contaminated sites. Permits
and environmental  controls are required for certain of the company's operations
to limit air and water pollution, and these permits are subject to modification,
renewal, and revocation by issuing authorities.  The company believes that it is
in substantial compliance with all material environmental laws, regulations, and
permits.  On an ongoing basis,  the company  incurs capital and operating  costs
relating to environmental  compliance.  Environmental  laws and regulations have
generally  become stricter in recent years, and the cost of responding to future
changes may be substantial.
      The  company's  environmental  reserves,  which are  included  in  current
liabilities,   totaled  $11,000  and  $12,600  at  August  31,  1999  and  1998,
respectively. The actual cost of environmental issues may be substantially lower
or higher than that reserved due to the  difficulty  in  estimating  such costs,
potential changes in the status of government regulations,  and the inability to
determine  the  extent  to which  contributions  will be  available  from  other
parties.  The company does not believe that any amount of such costs below or in
excess of that accrued is reasonably estimable.
      Certain  environmental  laws, such as Superfund,  can impose liability for
the entire cost of site remediation upon each of the current or former owners or
operators  of a site or  parties  who sent  waste to a site where a release of a
hazardous  substance has occurred  regardless of fault or the  lawfulness of the
original disposal activity.  Generally,  where there are a number of potentially
responsible  parties  ("PRPs") that are financially  viable,  liability has been
apportioned  based on the type and amount of waste  disposed of by each party at
such  disposal  site and the number of  financially  viable  PRPs,  although  no
assurance can be given as to any particular site.
      The  company is  currently a party to, or  otherwise  involved  in,  legal
proceedings in connection with several state and federal Superfund sites, two of
which are  located  on  property  owned by the  company.  Except  for the Crymes
Landfill and M&J Solvents matters in Georgia, the company believes its liability
is de minimis at each of the sites which it does not own where it has been named
as a PRP. At the Crymes  Landfill and M&J Solvents sites in Georgia,  since the
matters are  currently  in the  investigative  phase,  the company does not know
whether its  liability is de minimis but  believes  that its exposure at each of
the sites is not likely to result in a material  adverse  effect on the  company
due to its limited  involvement  at the sites and the number of viable PRPs. For
property  which the company  owns on Seaboard  Industrial  Boulevard in Atlanta,
Georgia,  the  company  has  conducted  an  investigation  on its and  adjoining
properties  and  submitted a Compliance  Status  Report  ("CSR") to the State of
Georgia  Environmental  Protection  Division  ("EPD")  pursuant  to the  Georgia
Hazardous  Site  Response  Act.  Until EPD's  review and approval of the CSR are
completed,  which are not subject to a deadline, the company will not be able to
determine  if  remediation  will be  required,  if the  company  will be  solely
responsible for the cost of such remediation,  or whether such cost is likely to
result in a material  adverse  effect on the  company.  For  property  which the
company  owns on East  Paris  Street in Tampa,  Florida,  the  company  has been
requested by the State of Florida to clean up chlorinated solvent  contamination
in the groundwater on the property and on surrounding property known as Seminole
Heights  Solvent  Site and to  reimburse  approximately  $430 of  costs  already
incurred  by the State of Florida in  connection  with such  contamination.  The
company  believes that it has a strong defense due to likely off-site sources of
the contamination and because  contamination from the property,  if any, was due
to prior owners and not the company's operations.  At this time, it is too early
to quantify the  company's  potential  exposure or the  likelihood of an adverse
result.
      The  company  is  currently   evaluating  emissions  of  volatile  organic
compounds from its  manufacturing  operations in the Atlanta,  Georgia,  area to
determine  whether it will need to install pollution control equipment or modify
its operations to comply with federal and state air pollution regulations. Until
the current  evaluations are completed,  the company is not able to quantify the
possible  cost  of  compliance.   However,   based  upon   currently   available
information,  the company does not expect that any material expenditures will be
required to achieve compliance.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                        National Service Industries, Inc.


      In  connection  with the sale of the North  Bros.  business  and 29 of the
company's  textile  rental  plants in 1997,  the  company has  retained  certain
environmental  liabilities  arising from events  occurring prior to the closing,
subject to certain exceptions. The company has received notice from the buyer of
the  textile  rental  plants  of  the  alleged  presence  of   perchloroethylene
contamination  on one of the  properties  involved in the sale.  The company has
since asserted an indemnification claim against the company from which it bought
the property.  The prior owner is currently  conducting an  investigation of the
contamination at its expense,  subject to a reservation of rights. At this time,
it is too early to quantify the company's potential exposure in this matter, the
likelihood  of an adverse  result,  or the  possibility  that the company may be
fully or partially indemnified.
      The State of New York has filed a lawsuit  against  the  company  alleging
that the company is responsible as a successor to Serv-All  Uniform Rental Corp.
for past and future  response costs in connection with the release or threatened
release of hazardous  substances at and from the Blydenburgh  Landfill in Islip,
New York.  The company  believes that it is not a successor to Serv-All  Uniform
Rental Corp.  and  therefore  has no liability  with respect to the  Blydenburgh
Landfill, and it has responded to the lawsuit accordingly.  At this stage of the
litigation,  it is too early to quantify the company's potential exposure or the
likelihood of an adverse result.

Note 6:  Restructuring Expense and Asset Impairments

During  1997,  the company  conducted  reviews of the textile  rental,  European
chemical,   and  corporate  operations  as  a  part  of  management's  strategic
initiatives to examine  under-performing  operations and to position the company
for  growth.  As a result of the  reviews,  the company  approved a  significant
restructuring  program and recorded a related charge of $9,600 during the fourth
quarter of 1997. The accrual included severance and union-related costs totaling
$2,950 for 120 employees of the textile rental, chemical, and envelope segments,
all of whom have since been  terminated,  and $6,650 in exit  expenses  to close
certain  facilities  and  consolidate  the  operations  of others in the textile
rental  segment.  Exit expenses  include costs of unexpired  leases and costs to
dispose of facilities.
           The major  components of the 1997  restructuring  charges and related
activity are as follows:



                     Reserve,                                              Reserve,
                     Beginning                Cash       Non-Cash          End of
                     of Period    Charge    Payments    Adjustments        Period

Exit costs          $    4,740           -        (390)        (750)  (1)   $  3,600


1997

Exit costs          $       -        6,650      (1,910)            -        $  4,740



(1) The  restructuring  reserves were reduced because the company realized lower
costs than  originally  anticipated  and also  revised its  estimate for certain
expenses included in the original  restructuring  plan due to lease terminations
or other changes.


      As a further result of the 1997 reviews, the company recognized long-lived
asset impairments  totaling $43,500.  Textile rental assets to be disposed of in
under-performing  branches  were  reduced  by  $22,300  to  state  them at their
estimated  fair value less costs to sell.  After the charge,  the  remaining net
book value of these  assets was  immaterial.  Fixed  assets  held for use by the
textile rental,  European chemical,  and corporate units were reduced by $12,400
and related intangibles were reduced by $8,800.  Impairments were recognized for
those assets where the sum of estimated  undiscounted future cash flows was less
than the carrying amount of the assets,  including related goodwill. Fair market
values were  established  based on independent  appraisals,  comparable sales or
purchases,  and expected  future cash flows  discounted at the company's cost of
capital. Factors leading to the impairments were a combination of the results of
the reviews discussed above,  historical losses,  anticipated future losses, and
inadequate cash flows.
     The losses  resulting  from the  accruals and  impairments  are included in
"Restructuring   expense,   asset   impairments,   and  other  charges"  in  the
Consolidated Statements of Income.
     During 1999,  management  performed an extensive  review of the assets that
were to be disposed of and the remaining  restructuring accruals. In addition to
realizing  lower than  anticipated  costs,  management has determined that it is
currently more  economically  feasible to continue to operate certain  locations
that were to be  disposed  of in the  original  plan.  As a result,  in 1999 the
related reserve and impairments  were reversed and $9,291 in income was recorded
and is included in "Restructuring expense, asset impairments, and other charges"
in the Consolidated Statements of Income.

                                                                        Page 115

Note 7:  Acquisitions and Divestitures

Acquisition  spending  in 1999  totaled  $534,977  ($534,132  in cash and 26,495
shares valued at $845) and was primarily  related to the lighting  equipment and
envelope  segments.  The  acquisitions  were  accounted  for as  purchases  and,
accordingly,  the  purchase  price was  allocated  to the  assets  acquired  and
liabilities assumed based on estimated fair values.
     The lighting  equipment  segment  acquired four companies  during 1999. The
largest acquisition was Holophane Corporation  ("Holophane"),  a manufacturer of
premium quality,  highly  engineered  lighting  fixtures and systems,  which was
purchased in July 1999 for approximately $470,811. The preliminary allocation of
the purchase price resulted in additional  goodwill of $251,781,  which is being
amortized over 40 years,  and  identifiable  intangibles of $145,725,  which are
being  amortized  over  periods  ranging  from  2  to  40  years.   Identifiable
intangibles include trade names, trademarks,  patented technology,  distribution
network,  trained workforce,  and restrictive  covenants.  Results of operations
after  the  acquisition  date of  Holophane  are  included  in the  Consolidated
Statements  of Income.  The following  pro forma  information  has been prepared
assuming  the  Holophane  acquisition  had taken place at the  beginning  of the
respective  fiscal  year of the  company.  The pro  forma  information  includes
adjustments for interest expense on debt incurred to effect the acquisition, the
interest  income  foregone  on  the  cash  portion  paid  for  the  acquisition,
additional  depreciation based on the fair market value of property,  plant, and
equipment,  and  amortization  of goodwill and  intangibles  resulting from this
transaction. The pro forma financial information does not purport to reflect the
financial  position or results of operations  that actually  would have resulted
had the transaction  occurred as of the date indicated or to project the results
of operations for any future period.

                                         ------------------------------------


      Other   acquisitions  in  the  lighting  equipment  segment  included  the
September 1998 purchase of certain assets of GTY Industries (d/b/a "Hydrel"),  a
manufacturer of architectural-grade light fixtures for landscape,  in-grade, and
underwater  applications;  the April 1999 purchase of certain assets of Peerless
Corporation,  a  manufacturer  of  high  performance  indirect/direct  suspended
lighting  products;   and  the  July  1999  purchase  of  C&G  Carandini  SA,  a
manufacturer  of exterior  lighting  fixtures.  In February  1999,  the envelope
segment acquired substantially all of Gilmore Envelope, an envelope manufacturer
headquartered  in Los Angeles,  California.  The company also made several minor
acquisitions in the textile rental segment.
      Divestitures   primarily  related  to  the  envelope   segment's  sale  of
Techno-Aide/Stumb  Metal  Products in June 1999 for  approximately  $4,191.  The
envelope segment  recognized a pretax gain of $1,990 on the  transaction.  Other
divestitures  during 1999  related to the sale of  industrial  contracts  in the
textile rental segment and were not material.
      During 1999,  management  performed an extensive review of the liabilities
recorded in connection  with the textile  rental  segment's  1997 uniform plants
divestiture.  In 1997, the textile  rental segment  accrued for items related to
the sale of its uniform  plants  including  environmental  exposures,  severance
agreements,  and costs to return leased facilities to pre-lease  condition.  The
company has realized lower costs than  originally  anticipated  associated  with
these  items and,  as a result,  reduced the  liability  and  recorded a gain of
$3,511.
      Acquisition  spending in 1998 totaled $45,305 and was primarily related to
the chemical and  envelope  segments.  In November  1997,  the chemical  segment
purchased  Pure  Corporation,  a  speciality  chemical  company  with  its  core
businesses in Indiana,  Pennsylvania,  and New York. In March 1998, the envelope
segment purchased Allen Envelope Corporation, a single-plant, Pennsylvania-based
envelope  manufacturer,  providing  the  segment  with  access to markets in the
Northeast.  In  July  1998,  the  company  purchased  Calman  Australia  Pty Ltd
("Calman").  Calman,  located  in  Victoria,  Australia  is  a  manufacturer  of
cleaning, maintenance,  sanitation and industrial products, chemicals, supplies,
and accessories.  Additionally,  the company paid certain  performance  payments
associated  with a prior year  chemical  acquisition.  Divestitures  during 1998
related  to the  textile  rental  segment  and  excess  properties  and were not
material.
      In February 1997, the company sold the North Bros. insulation business for
$27,113 in cash. An immaterial  gain was realized on the sale.  The business had
1997 sales of $57,000 and operating income of $1,900.  Additionally,  immaterial
gains were  recognized as the company  divested  several  non-strategic  textile
rental locations.
      In July 1997, the company sold 29 textile rental plants to G & K Services,
Inc. at a pretax gain of $74,044. The following condensed pro forma consolidated
statements of income present reported results for the respective fiscal years to
remove both the gain on the transaction and the results of the operations sold:

      The pro forma  statements are not necessarily  indicative of the financial
position  and  results  of  operations  that would  have been  attained  had the
divestiture  been  consummated on the dates indicated or that may be attained in
the future.
      In 1997, cash  acquisition  spending  totaled $4,320 and was the result of
the  chemical  segment's  purchase of chemical  products  companies  in Ohio and
Canada and the lighting  equipment  segment's  acquisition of a small  emergency
lighting products manufacturer in Canada. The company also issued 536,872 shares
of  common  stock  valued  at  $20,522  to  acquire  Enforcer   Products,   Inc.
("Enforcer"),  a specialty  chemical  company with a retail focus. The operating
results of Enforcer were  included in the chemical  segment  beginning  with the
third quarter of fiscal 1997.

Note 8:  Income Taxes

The company accounts for income taxes using the asset and liability  approach as
prescribed by SFAS 109,  "Accounting  for Income Taxes." This approach  requires
recognition of deferred tax  liabilities  and assets for the expected future tax
consequences  of events that have been included in the  financial  statements or
tax  returns.  Using the  enacted  tax rates in effect for the year in which the
differences  are expected to reverse,  deferred tax  liabilities  and assets are
determined based on the differences  between the financial reporting and the tax
basis of an asset or liability.
      The provision for income taxes consists of the following components:

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS


National Service Industries is a diversified  service and manufacturing  company
operating in four segments: lighting equipment,  chemicals,  textile rental, and
envelopes.  The company  continued to be in solid financial  condition at August
31, 1999.  Although down from last year, net working capital  remained strong at
$256.5 million at August 31, 1999, and the current ratio was 1.6,  compared with
2.7 at the prior year end. The decrease in net working capital was primarily the
result  of a  decrease  in cash and an  increase  in debt to fund  acquisitions,
capital expenditures, share repurchases, and payment of dividends. At August 31,
1999, the company's debt to  capitalization  increased to 47.2 percent  compared
with 12.9 percent at the prior year end.

Strategic Transactions
The company periodically  implements  strategic  transactions that, it believes,
afford it the opportunity to redeploy resources to create value and position the
company for future growth.  During the three-year period ending August 31, 1999,
the following transactions occurred:

Acquisitions
Acquisition  spending in 1999 totaled $534.9 million ($534.1 million in cash and
$0.8 million in stock) and was primarily  related to the lighting  equipment and
envelope  segments.  In July 1999,  the  lighting  equipment  segment  purchased
Holophane Corporation  ("Holophane"),  a manufacturer of premium quality, highly
engineered lighting fixtures and systems, for approximately $471 million.  Other
acquisitions  in the lighting  equipment  segment  included the  September  1998
purchase of certain assets of GTY Industries (d/b/a "Hydrel"), a manufacturer of
architectural-grade  light  fixtures for  landscape,  in-grade,  and  underwater
applications;  the April 1999 purchase of certain assets of Peerless Corporation
("Peerless"),  a  manufacturer  of high  performance  indirect/direct  suspended
lighting  products;   and  the  July  1999  purchase  of  C&G  Carandini  SA,  a
manufacturer  of exterior  lighting  fixtures.  In February  1999,  the envelope
segment acquired substantially all of Gilmore Envelope, an envelope manufacturer
headquartered  in Los Angeles,  California.  The company also made several minor
acquisitions in the textile rental segment.
      In 1998,  acquisition  spending  totaled  $45.3  million and was primarily
related to the chemical and envelope  segments.  In November  1997, the chemical
segment purchased Pure Corporation,  a specialty  chemical company with its core
businesses in Indiana,  Pennsylvania,  and New York. In March 1998, the envelope
segment  purchased  Allen  Envelope  Corporation   ("Allen"),   a  single-plant,
Pennsylvania-based  envelope manufacturer,  providing the segment with access to
markets in the Northeast.  In July 1998, the company  purchased Calman Australia
Pty Ltd ("Calman"). Calman, located in Victoria, Australia, is a manufacturer of
cleaning, maintenance,  sanitation and industrial products, chemicals, supplies,
and accessories.  Additionally,  the company paid certain  performance  payments
associated with a prior year chemical acquisition.
      In 1997,  acquisition  spending totaled $4.3 million and resulted from the
chemical  segment's  purchase of chemical products  companies in Ohio and Canada
and the lighting equipment  segment's  acquisition of a small emergency lighting
products  manufacturer in Canada. In March 1997, the company also issued 536,872
shares of common stock  valued at $20.5  million to acquire  Enforcer  Products,
Inc. ("Enforcer"), a specialty chemical company with a retail focus.

Divestitures
In 1999, proceeds from divestitures  totaled $12.0 million and primarily related
to the envelope segment's sale of Techno-Aide/Stumb  Metal Products in June 1999
resulting in proceeds of $4.2 million and a pretax gain of $2.0  million.  Other
divestitures  during 1999  related to the sale of  industrial  contracts  in the
textile rental segment and were not material.
      During 1999,  management  performed an extensive review of the liabilities
recorded in connection  with the textile  rental  segment's  1997 uniform plants
divestiture.  In 1997, the textile  rental segment  accrued for items related to
its uniform plants including environmental exposures,  severance agreements, and
costs to return leased facilities to pre-lease  condition.  The company realized
lower costs than  originally  anticipated  associated with these items and, as a
result, has reduced the liability and recorded a gain of $3.5 million.
     In 1998, divestitures of non-strategic textile rental operations and excess
properties  resulted in net  proceeds of $3.1  million and pretax  gains of $2.4
million.
     In February 1997, the company sold the North Bros.  insulation business for
cash of $27.1  million,  recognizing  an immaterial  gain. The business had 1997
sales of $57.0 million and operating  income of $1.9 million through the date of
sale.
     In July 1997,  the company sold 29 textile  rental  plants to G&K Services,
Inc.  for  approximately  $280.0  million,  recognizing  a pretax  gain of $74.0
million.  The divested  locations had 1997 sales of $176.5 million and operating
income of $9.4 million through the date of sale.
      Additionally, in 1997, the company divested other non-strategic businesses
in the textile rental segment generating cash of $4.3 million.

Liquidity and Capital Resources

Operating Activities
Operations  provided cash of $208.2 million in 1999, compared with cash provided
of $26.4  million  in 1998 and  $125.5  million in 1997.  The  increase  in 1999
primarily resulted from additional tax payments made in 1998 related to the 1997
textile rental segment divestitures,  improved working capital management in the
lighting  equipment and chemical  segments,  and an increase in net income.  The
decrease in 1998 compared with 1997 was primarily the result of the tax payments
and an increase in accounts  receivable  commensurate with the increased revenue
in the lighting equipment and chemical segments.

Investing Activities
Investing  activities  used cash of $598.0  million in 1999 and provided cash of
$81.3 million and $61.1 million in 1998 and 1997, respectively.  The decrease in
1999 was a result of the significant  increase in acquisition  spending  coupled
with the liquidation of short-term investments during 1998 that was not repeated
during the current  year.  The increase in 1998 compared with 1997 is the result
of the  liquidation  of $205.3 million of short-term  investments,  generated by
1997  divestitures,   to  fund   acquisitions,   capital   expenditures,   share
repurchases,  and payment of dividends.  Capital expenditures were $72.3 million
in 1999,  compared with $82.0 million in 1998 and $48.8 million in 1997. Capital
spending  during 1999 was  primarily  attributable  to the  lighting  equipment,
textile rental, and envelope segments.  The lighting equipment segment's capital
expenditures  related to the  purchase  of land and  buildings  for a new plant,
manufacturing   improvements   and   upgrades  for   capacity   expansion,   and
implementation  of new  technology.  Expenditures  in the textile rental segment
were for implementation of new technology, production enhancements, and delivery
truck purchases and refurbishments.  The envelope segment's expenditures related
primarily to manufacturing process improvements,  information systems,  facility
expansion, and new folding capacity. During 1998, the lighting equipment segment
invested in facility  expansions and  manufacturing  process  improvements,  the
textile  rental  segment  invested in a  merchandise  tracking  system and fleet
refurbishment,  and the  envelope  segment  invested in facility  and  machinery
replacements. Capital spending in 1997 consisted primarily of lighting equipment
segment facilities and process improvements, equipment replacements, and tooling
for  new  products  and  textile

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (continued)


rental segment  facilities  improvements  and equipment  replacements.  In 2000,
capital  expenditures  are expected to  approximate  $110 million as the company
continues  to  invest   capital  in  technology  and   facilities.   Contractual
commitments  for  capital  and   acquisition   spending  for  fiscal  year  2000
approximate $24 million.
      As  noted  under   "Acquisitions"  and  "Divestitures,"  the  company  has
completed a number of strategic transactions.  The company spent $534.1 million,
$45.3  million,  and $4.3  million in 1999,  1998,  and 1997,  respectively,  on
acquisitions.  Additionally,  the company received $12.0 million,  $3.1 million,
and $311.4 million in connection with  dispositions of  non-strategic  assets in
1999, 1998, and 1997, respectively.

Financing Activities
Financing  activities  provided cash of $372.9 million during 1999 and used cash
of $145.2  million  and $187.6  million in 1998 and 1997,  respectively.  In the
three years ending August 31, 1999, the company distributed approximately $476.3
million to stockholders  through share repurchases and dividends.  Cash of $42.0
million,  $154.0  million,  and $121.7  million was utilized in 1999,  1998, and
1997,  respectively,  for share repurchases of 1.2 million, 3.0 million, and 3.0
million  shares,  respectively.  Although  the  company  has a  standing  annual
authorization  to  repurchase  2.0 million  shares plus the number of new shares
issued in any one year, the company does not plan to purchase  additional shares
until its ratio of total debt to  capitalization  is within the company's stated
objective  of 30 to 40  percent.  Included  in the 1998 and 1997  amounts  was a
supplemental  authorization for the repurchase of 1.25 million shares granted as
a result  of the  textile  rental  divestiture  transaction.  Additionally,  the
company distributed cash of $51.9 million,  $52.6 million,  and $54.2 million in
1999, 1998, and 1997, respectively, to the company's stockholders in the form of
dividends.  The  increase in dividends to $1.27 per share in 1999 from $1.23 per
share in 1998  represented an increase of 3.3 percent,  marking the  sixty-third
consecutive year of quarterly dividends without a decrease.
      In 1996, the company  negotiated a $250 million  multi-currency  committed
credit  facility  (the "Credit  Facility")  with ten domestic and  international
banks. The Credit Facility has a term of five years, expiring in July 2001, with
no  provision  for a reduction  in  commitments.  The Credit  Facility  contains
restrictions  on the  incurrence of  indebtedness  by  subsidiaries,  as well as
financial  and other  covenants,  including the  restriction  that the company's
ratio of total debt to capitalization may not exceed 60 percent at any time.
      During  the fourth  quarter  of 1998,  the  company  filed a  registration
statement (the "shelf registration"),  which became effective September 8, 1998,
with the  Securities  and Exchange  Commission to allow the company to offer for
sale, from time to time, up to $400 million of unsecured  senior debt securities
or  unsecured  senior  subordinated  debt  securities  (the  "Debt  Securities")
consisting of notes,  debentures,  or other evidence of  indebtedness,  of which
$240 million  remains  available at August 31, 1999. The Debt  Securities may be
convertible  into or  exchangeable  for shares of the  company's  common  stock,
shares of its preferred stock, or other Debt Securities. The Debt Securities may
be offered as a single series or as two or more separate  series in amounts,  at
prices  and on terms to be  determined  at the  time of the  offering.  The Debt
Securities may be sold to or through one or more agents  designated from time to
time.
      In January 1999, the company  issued $160.0  million in ten-year  publicly
traded notes  bearing a coupon rate of 6.0 percent.  Proceeds  were used for the
repayment of $80.0 million in  borrowings  under the Credit  Facility,  of which
$52.0  million was  outstanding  under the domestic line of credit at August 31,
1998. The remainder was used for general  corporate  purposes  including working
capital requirements, capital expenditures, acquisitions, and share repurchases.
In July 1999, the company  entered into an additional  $250.0  million,  364-day
committed  credit facility (the "Revolving  Credit  Facility")  expiring in July
2000. The combined  $500.0  million under the Credit  Facility and the Revolving
Credit  Facility  support the  company's  commercial  paper  program,  which was
initiated in July 1999 primarily to fund the acquisition of Holophane.
      At August 31, 1999, the company had $352.3 million  outstanding  under its
commercial paper program, of which $249.7 million was classified as long-term as
the company intends to refinance this amount through  long-term debt instruments
or  availability  under the Credit  Facility  which matures in 2001.  Short-term
commercial paper of $102.5 million had an average interest rate of 5.8 percent.
      The company has complimentary  lines of credit totaling $125.7 million for
general   operating   purposes,   of  which  $25.7   million  is  designated  as
multi-currency.  At August 31,  1999,  $76.9  million in letters of credit  were
outstanding,  primarily under the domestic line of credit. The company had $10.9
million of foreign  currency  short-term bank borrowings  outstanding  under the
multi-currency line of credit at a weighted average interest rate of 3.8 percent
at August 31, 1999.
      Management  believes  current cash balances,  anticipated  cash flows from
operations,  and  available  funds  from the  commercial  paper  program  or the
committed  credit  facilities,  complimentary  lines of  credit,  and the  shelf
registration  are  sufficient  to meet the  company's  planned  level of capital
spending and general operating cash requirements for the next twelve months.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (continued)


      National Service Industries posted revenues of $2.2 billion for the fiscal
year ended August 31, 1999.  The revenue  increase in 1999 in  comparison to the
prior year resulted from increased lighting  equipment,  chemical,  and envelope
revenues of approximately $192 million, partially offset by a slight decrease in
revenue in the textile rental  segment.  Revenues in 1998 decreased  slightly in
comparison  with the prior  year as a result of  increased  lighting  equipment,
chemical, and envelope revenues of approximately $233 million,  offset primarily
by revenues not included in 1998 as a result of 1997 divestitures.
      Net income for 1999 increased $15.6 million,  or 14.4 percent, to a record
level of $124.3 million,  or $3.04 per basic share, $3.03 diluted.  Earnings per
share grew at the higher rate of 18.8  percent per basic share and 19.8  percent
per  diluted  share due to a  reduction  of 1.6  million  basic and 1.9  million
diluted average shares  outstanding.  Net income in 1998 increased $1.4 million,
or 1.3 percent, to $108.7 million, or $2.56 per basic share, $2.53 diluted.
     Lighting equipment segment sales grew $115.3 million,  or 10.4 percent,  to
$1.2 billion in 1999.  Continued  strength in the  non-residential  construction
market and the acquisitions of Hydrel,  Peerless,  and Holophane  contributed to
the growth in sales. As a result of the increased sales and  manufacturing  cost
savings,  operating  profit  increased  11.4  percent  in 1999.  Sales  for 1998
increased 16.1 percent due to strong demand in the non-residential  construction
market and increased volumes  resulting from new products.  Operating profit for
1998  increased  18.3  percent as a result of the  increased  sales and  ongoing
productivity improvements.
      Chemical  segment  revenues  for  1999  increased  $33.3  million,  or 7.3
percent,  to $487.8  million.  The increase in revenue was a result of continued
growth in the retail channel, higher revenue in the industrial and institutional
distribution   channels,   inclusion  of  a  full  year  of  Calman,  and  other
international revenue. Operating profit increased $8.7 million, or 24.0 percent,
to $45.2 million as a result of the increased  revenues,  lower operating costs,
and severance costs included in 1998 that were not repeated in 1999. Revenues in
1998  increased  12.9  percent  as a result of the  inclusion  of a full year of
Enforcer as well as increased  retail volumes of Enforcer and Zep  Manufacturing
Company.  Operating  profit in 1998  increased  15.5  percent as a result of the
increased  revenues  and the  impact  of the 1997  restructuring  charge on 1997
operating  profit.  These increases in operating  profit were somewhat offset by
additional  severance  costs and  increased  selling  expenses  incurred  in the
industrial chemical channel of the segment.
      Textile rental segment revenues, representing all of the company's service
revenues,  decreased 1.2 percent during 1999 to $309.1  million,  primarily as a
result of the continued sale of industrial  contracts and the rationalization of
unprofitable accounts. Operating profit increased 44.4 percent to $42.9 million,
primarily  as a  result  of  gains  recognized  on the  sale of  businesses  and
adjustments  made to amounts  accrued in connection with the 1997 uniform plants
divestiture  and 1997  restructuring  activities.  In 1997,  the textile  rental
segment  accrued for items related to the sale of its uniform  plants  including
environmental  exposures,  severance  agreements,  and  costs to  return  leased
facilities  to  pre-lease  condition.  The  company  realized  lower  costs than
originally  anticipated  and  recorded a gain of $3.5  million as  discussed  in
"Strategic  Transactions."  In 1997,  the segment  also  recorded an  impairment
charge and accrued for items related to restructuring  activities that primarily
related  to  branch  consolidations  and  asset  dispositions.  In  addition  to
realizing  lower  than  anticipated  costs,  management  determined  that  it is
currently more  economically  feasible to continue to operate certain  locations
that were to be  disposed  of in the  original  plan.  As a result,  in 1999 the
related  reserve and  impairments  were  reversed and $9.3 million in income was
recorded.  Excluding  unusual  gains and other  non-operating  items in 1999 and
1998, operating profit increased slightly due to the segment's focus on lowering
merchandise costs and improving production efficiencies. Segment revenue in 1998
decreased 36.6 percent as a result of businesses divested in 1997. Excluding the
1997 divestiture,  revenues declined  approximately  $4.0 million as the segment
continued to eliminate  low-margin  customer accounts.  Operating profit in 1998
decreased  51.2  percent  to $29.7  million,  primarily  as a result of the 1997
divestitures.
      Envelope segment revenue increased $43.0 million, or 27.1 percent, in 1999
to $201.7 million  primarily as a result of the acquisitions of Gilmore Envelope
in  February  1999 and Allen in March  1998.  Operating  profit for the  segment
increased 32.9 percent to $17.7 million primarily as a result of the gain on the
sale  of   Techno-Aide/Stumb   Metal   Products,   as  discussed  in  "Strategic
Transactions,"  the  acquisition of Gilmore  Envelope,  and increased  revenues.
Segment revenue in 1998 increased 21.2 percent due to the March 1998 purchase of
Allen, as discussed in "Strategic  Transactions,"  and higher shipment  volumes.
Operating profit increased 30.4 percent during 1998 as a result of the increased
revenues generated by the Allen acquisition.
      Corporate  expenses in 1999  approximated  last year.  In 1998,  corporate
expenses  decreased $1.3 million,  as 1997 expense  included an asset impairment
recorded to reflect the $1.2 million  appraised value of an asset held for sale.
Net  interest  expense  increased  $13.3  million  in 1999 as a result of higher
average debt levels  coupled  with lower  average  cash  balances.  Net interest
expense  decreased  $0.8  million in 1998 as the company  benefited  from higher
average levels of short-term investments, offset slightly by higher average debt
levels.
      Consolidated income before taxes increased $25.2 million, or 14.6 percent,
to $198.3 million primarily due to increased income from the lighting equipment,
chemical,  and envelope  segments.  Additionally,  gains realized on the sale of
businesses and related to adjustments to restructuring  reserves and impairments
originally  recorded in 1997 in the textile rental segment  positively  affected
income. The provision for income taxes was 37.3 percent,  37.2 percent, and 40.1
percent in 1999,  1998,  and 1997,  respectively.  The decrease in the effective
rate in 1998 was due  primarily to higher rates  applicable  to the 1997 textile
rental divestiture.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (continued)


Market Risk
The company is exposed to market risks that may impact the Consolidated  Balance
Sheets,  Consolidated  Statements of Income, and Consolidated Statements of Cash
Flows due to changing  interest rates and foreign  exchange  rates.  The company
does not currently  participate in any significant hedging activities,  nor does
it utilize any  significant  derivative  financial  instruments.  The  following
discussion provides additional information regarding the company's market risks.

Interest Rates-The company's commercial paper, notes payable,  fixed-rate notes,
and other  long-term  debt are  subject to  interest  rate  fluctuations.  These
fluctuations expose the company to changes in interest expense,  cash flows, and
the fair market  value of the  instruments.  The  company's  variable-rate  debt
amounted to $387.0 million at August 31, 1999.  Based on outstanding  borrowings
at year end, a 10 percent  adverse change in effective  market interest rates at
August 31, 1999 would result in additional annual after-tax  interest expense of
approximately  $1.3  million.  To address  this  risk,  the  company  intends to
refinance  approximately  $250 million of the outstanding  commercial paper on a
long-term,  fixed-rate basis. Although a fluctuation in interest rates would not
affect  interest  expense or cash flows  related to the  company's  $160 million
publicly traded notes, a 10 percent adverse change in effective  market interest
rates  at  August  31,  1999  would  decrease  the fair  value  of the  notes to
approximately $138.2 million.

Foreign  Exchange  Rates-The  majority of the company's  revenue,  expense,  and
capital  purchases are  transacted in U.S.  dollars.  International  operations,
primarily   the   lighting   equipment   and  chemical   segments,   represented
approximately  7.1  percent  of sales  and  service  revenues,  1.4  percent  of
operating  profit (loss),  and 8.5 percent of identifiable  assets.  The company
does not believe a 10 percent  fluctuation  in average  foreign  currency  rates
would have a material effect on its consolidated financial statements or results
of operations.

Impact of the Year 2000 Issue
The "Year  2000  Issue"  resulted  from the use of two digits  rather  than four
digits to define the  applicable  year in certain  computer  programs.  With the
coming  millennium,  any of the company's  computer programs that have two-digit
date-sensitive  software  may  interpret  a date of "00" as the year 1900 rather
than the year 2000.  This  could  result in a system  failure or  miscalculation
causing  disruption of the operation of computer hardware and software,  as well
as intelligent manufacturing equipment and processes, and telephony.
      Management  is addressing  the Year 2000 Issue in four phases:  awareness,
assessment, action plan, and plan implementation.  At August 31, 1999, all areas
of the company had  completed the first three phases and  implementation  of the
plan was substantially complete.  Management estimates that the total cost to be
incurred  in  connection  with the Year  2000  Issue  will be  approximately  $6
million, and all major systems are expected to be in compliance prior to the end
of calendar year 1999. At August 31, 1999,  the company had spent  approximately
$4.7  million on the Year 2000 Issue.  The cost of the  project is being  funded
through operating cash flows. Approximately one-third of the total cost reflects
the  redeployment  of existing  internal  information  technology  resources and
should not be incremental costs to the company.
      At this time, the company  believes its most reasonably  likely worst case
scenario is that key suppliers or service  providers who have not resolved their
own Year 2000 Issue may cause a disruption of service to the company's  critical
business  processes.  Management  has evaluated  the  potential  exposure of the
company to related problems of its customers and suppliers and has implemented a
vendor  certification  process.  While  management  believes  that  its  plan is
sufficient  to  address  the  Year  2000  Issue,  management  has  substantially
completed a contingency plan to address the potential for unforeseen issues that
may arise. The contingency plan includes identifying  alternative  suppliers and
increasing  inventory  levels.  There can be no  assurance,  however,  that such
exposures or the costs of remediating any problems associated therewith will not
materially affect the company's future business, financial condition, or results
of operations.

Outlook
Management  continues to execute its strategic plan to grow both  internally and
through  acquisitions.  Fiscal  2000  sales  from the  existing  businesses  are
anticipated  to grow at a rate in excess of 5.0  percent,  led  primarily by the
lighting  equipment segment through continued lighting equipment market strength
and in the  chemical  segment  by product  development  and growth in the retail
market.  Assuming  there are no  significant  changes  in the  current  economic
environment,  management  expects  earnings to be lower than 1999 results due to
the Holophane acquisition,  which is expected to dilute earnings by 13 cents per
share, and unusual gains included in 1999 results that are not planned in fiscal
2000.

Cautionary Statement Regarding Forward-Looking Information
From time to time, the company may publish  forward-looking  statements relating
to such  matters  as  anticipated  financial  performance,  business  prospects,
capital expenditures,  technological  developments,  new products,  research and
development  activities,  and similar matters. The Private Securities Litigation
Reform  Act of 1995  provides  a safe  harbor  for  forward-looking  statements.
Statements  herein  which  may  be  considered   forward-looking   include:  (a)
statements  made regarding the company's  current  expectations  or beliefs with
respect  to  the  outcome  and  impact  on  the  company's  business,  financial
condition,  or  results  of  operations  of the Year 2000  Issue,  environmental
issues,  and legal  proceedings;  (b) statements  made  concerning  management's
expectations  with  respect to the  company's  plan for  strategic  growth;  (c)
statements  made regarding  management's  expectations  with regard to projected
capital  expenditures,  future cash flows, debt refinancing,  share repurchases,
and debt to  capitalization  objectives;  and (d) statements  made regarding the
acquisition  of  Holophane.  The company  notes that a variety of factors  could
cause the company's actual results and experience to differ  materially from the
anticipated   results  or  other   expectations   expressed  in  the   company's
forward-looking  statements.  The risks and  uncertainties  that may  affect the
operations,  performance,  development,  and results of the  company's  business
include  without  limitation  the  following:  (a) the  uncertainty  of  general
business and economic  conditions,  including  the  potential  for a slowdown in
non-residential  construction awards, fluctuations in commodity and raw material
prices,  market  demand for public  debt,  interest  rate  changes,  and foreign
currency  fluctuations;  and (b) the ability to achieve  strategic  initiatives,
including  but  not  limited  to  the   achievement  of  synergies   related  to
acquisitions  and the  achievement of sales growth across the business  segments
through a combination of increased pricing,  enhanced sales force, new products,
improved customer service, and acquisitions.
