             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
                 (In thousands, except share and per share data)


1.   BASIS OF PRESENTATION

The interim consolidated financial statements included herein have been prepared
by the company without audit and the condensed  consolidated balance sheet as of
August 31, 1998 has been  derived  from  audited  statements.  These  statements
reflect adjustments,  all of which are of a normal, recurring nature, which are,
in the  opinion of  management,  necessary  to present  fairly the  consolidated
financial  position as of May 31, 1999, the  consolidated  results of operations
for the  three  months  and nine  months  ended May 31,  1999 and 1998,  and the
consolidated cash flows for the nine months ended May 31, 1999 and 1998. Certain
reclassifications  have been made to the prior year's  financial  statements  to
conform to the current year's  presentation.  Certain  information  and footnote
disclosures  normally  included in financial  statements  prepared in accordance
with generally  accepted  accounting  principles have been condensed or omitted.
The company  believes that the  disclosures are adequate to make the information
presented not  misleading.  It is suggested that these  financial  statements be
read in conjunction with the financial  statements and notes thereto included in
the  company's  Annual  Report on Form 10-K for the fiscal year ended August 31,
1998.

The results of  operations  for the three  months and nine months  ended May 31,
1999 are not  necessarily  indicative of the results to be expected for the full
fiscal year because the company's  revenues and income are  generally  higher in
the second  half of its fiscal year and  because of the  uncertainty  of general
business conditions.


2.    BUSINESS SEGMENT INFORMATION

During the first  quarter of fiscal  1999,  the  company  adopted  Statement  of
Financial Accounting Standards (SFAS) No. 131, "Disclosures about Segments of an
Enterprise and Related Information." The objective of SFAS No. 131 is to provide
information  about  the  different  types of  business  activities  in which the
company engages. The following have been identified as reportable segments:
lighting equipment, chemical, textile rental, and envelope.

4.    EARNINGS PER SHARE

During the quarter ended  February 28, 1998,  the company  adopted  Statement of
Financial  Accounting  Standards  (SFAS) No. 128,  "Earnings  per Share."  Basic
earnings  per share is computed by dividing  net  earnings  available  to common
stockholders by the weighted average number of common shares  outstanding during
the period.  Diluted  earnings per share is computed  similarly but reflects the
potential  dilution  that could occur if dilutive  options were  exercised.  The
following table  calculates basic earnings per common share and diluted earnings
per common share at May 31:

5.    COMPREHENSIVE INCOME

The company adopted SFAS No. 130, "Reporting Comprehensive Income," in the first
quarter of fiscal 1999.  SFAS No. 130 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.  Other  comprehensive  income (loss) for the three and nine months ended
May 31, 1999 and 1998 includes only foreign  currency  translation  adjustments.
The calculation of comprehensive income is as follows:

6.    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 totaled $11,720 and $12,600 at May 31, 1999
and August 31, 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 such
amount below or in excess of that accrued is reasonably estimable.



<PAGE>


                                                                          Page 9

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.  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 of the CSR is completed,  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  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 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 any material expenditures to achieve compliance.

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.  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. 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
certain environmental liabilities in connection with the Blydenburgh Landfill in
Islip,  New York.  The company  believes that it has a strong defense that it is
not a successor to Serv-All  Uniform  Rental Corp. At this time, it is too early
to quantify the  company's  potential  exposure or the  likelihood of an adverse
result.


7.    INCREASE IN SHARES AUTHORIZED

On January 6, 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.

8.    SUBSEQUENT EVENTS

On June 21, 1999, the company announced the execution of a definitive  agreement
to  purchase  for  cash  all   outstanding   shares  of  Holophane   Corporation
("Holophane")  for $38.50 per share, or a total of  approximately  $450 million.
Holophane  is a leading  manufacturer  and marketer of premium  quality,  highly
engineered  lighting  fixtures  and  systems  for a wide  range  of  industrial,
commercial,  and outdoor applications.  The company commenced a tender offer for
all of  Holophane's  outstanding  shares on June 25, 1999.  The  transaction  is
subject to a majority  of  Holophane's  shares  being  tendered in the offer and
customary closing conditions. The transaction is expected to be completed in the
fourth quarter of NSI's fiscal 1999 and will be accounted for using the purchase
method of accounting.

In June, 1999, the company sold the envelope segment's  Techno-Aide/Stumb  Metal
Products  ("Techno-Aide")  business to BSC  Enterprises,  LLC.  Techno-Aide is a
leading  manufacturer  and  marketer of  accessory  products  for users of X-ray
equipment  with annual  revenues of  approximately  $4.0  million.  The envelope
segment realized a pretax gain of $2.0 million on the transaction.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following  discussion  should be read in conjunction  with the  consolidated
financial statements and related notes.

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 strong financial condition at May 31,
1999. Net working capital was $447.6  million,  up from $385.1 million at August
31, 1998, and the current ratio was 3.0 compared with 2.7 at August 31, 1998. At
May 31, 1999,  the company's  debt to  capitalization  increased to 25.2 percent
compared with 12.9 percent at August 31, 1998.

Results of Operations

National Service Industries generated revenue of $569.8 million and $1.6 billion
in the three and nine months ended May 31,  1999,  respectively,  compared  with
revenue of $521.6  million and $1.5  billion in the three and nine months  ended
May 31, 1998,  respectively.  Revenue increased  primarily due to the April 1999
acquisition of Peerless  Lighting  Corporation  ("Peerless"),  the February 1999
acquisition  of Gilmore  Envelope  Corporation  ("Gilmore"),  the September 1998
acquisition of GTY Industries  (d/b/a  "Hydrel"),  the July 1998  acquisition of
Calman  Australia  Pty Ltd,  and the March 1998  acquisition  of Allen  Envelope
("Allen").  Additionally, the revenue increase was due in part to higher revenue
in the base business of the lighting equipment and chemical segments.

Third quarter 1999 net income totaled $30.5 million,  or $.75 per diluted share,
compared to net income of $28.1 million, or $.66 per diluted share, for the same
period in the prior year.  The increase in income  related to the base  business
and   acquisitions   was  offset  by  an  increase  in  net  interest   expense.
Additionally,  the current  quarter  included a $2.3 million  pretax gain on the
sale of industrial  contracts in the textile rental segment.  Net income for the
nine months ended May 31, 1999 increased 3.5 percent to $81.0 million,  or $1.97
per diluted  share,  primarily  due to  increased  volume in the base  business,
income from acquisitions not included in the prior year results, a non-recurring
$3.5 million net pretax gain in the textile rental  segment,  and a $2.3 million
pretax gain on the sale of industrial  contracts in the textile rental  segment.
These items were  partially  offset by an increase in net  interest  expense and
gains recorded on the sale of businesses in the prior year. Diluted earnings per
share also increased due to the reduction of diluted average shares  outstanding
for the three and nine months ended May 31, 1999 by 1.8 million and 2.1 million,
respectively.

The lighting  equipment  segment  reported  revenue of $306.2 million and $862.9
million for the three and nine months ended May 31, 1999, respectively, which is
an increase of 10.3  percent and 7.0 percent  over the same periods in the prior
year.  This increase  resulted from  continued  strength in the  non-residential
construction  market  and  the  acquisitions  of  Peerless  and  Hydrel,  offset
partially by  competitive  pricing  measures.  Operating  profit  increased 10.8
percent to $29.0  million for the  quarter and 7.3 percent to $82.3  million for
the nine months ended May 31, 1999 primarily related to the additional sales and
lower material costs.

Chemical  segment revenue  increased 6.8 percent to $127.2 million for the third
quarter and 8.6 percent to $360.7 million for the nine months ended May 31, 1999
primarily due to continued growth in the retail channel, higher revenue from the
industrial and institutional  distribution  channels, and acquired international
revenue.  Operating  profit of $11.5  million and $29.8 million in the three and
nine months ended May 31,  1999,  respectively,  was  slightly  higher than last
year's  results as increased  revenues  were offset by higher  selling and other
operating costs.

Textile rental segment  revenue was $80.1 million for the quarter  compared with
$79.5  million  for the three  months  ended May 31,  1998 while  third  quarter
operating income  increased to $10.2 million from last year's $8.7 million.  The
increase in operating  income for the three months ended May 31, 1999  primarily
relates  to a $2.3  million  pretax  gain  associated  with the sale of  certain
industrial customer contracts partially offset by non-operating gains recognized
during the same period of the prior year.  Revenue for the nine months ended May
31, 1999  decreased 2.4 percent to $229.3  million  primarily as a result of the
sale of several  industrial  contracts and the  rationalization  of unprofitable
accounts in fiscal  1998.  Year to date 1999  revenue  was also  affected by the
temporary,  negative  impact  of two  hurricanes  on nine  southeastern  plants.
Operating  income for the nine  months  ended May 31,  1999  increased  to $26.1
million from $21.5  million for the same period in the prior year.  Year to date
1999  operating  income  includes a $5.7 million gain  associated  with the 1997
uniform plants divestiture and restructuring activities offset by a $2.2 million
write-off for merchandise  inventory  previously used by unprofitable  accounts.
Additionally,  year to date income  includes a $2.3  million gain on the sale of
industrial  contracts.  Excluding  non-recurring  items in the current and prior
year,  operating  margins for the quarter and year to date  increased due to the
segment's  focus  on  lowering   merchandise  costs  and  improving   production
efficiencies through the daily tracking of operational performance measures.

During the second quarter of 1999,  management  performed an extensive review of
the liabilities recorded in 1997 in connection with the textile rental segment's
uniform plants  divestiture and 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 has 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  during the second
quarter of 1999.  Additionally,  in 1997 the textile rental segment  recorded an
impairment charge and accrued for items related to restructuring activities that
primarily  related  to  branch  consolidations  and asset  dispositions.  As the
company has realized lower than  anticipated  costs, the reserve was reduced and
income of $2.2 million was recorded  during the second  quarter of 1999.  During
the current  year,  the  restructuring  reserves  were also reduced by a minimal
amount for payments related to plant consolidations.

Envelope  segment revenue  increased 23.8 percent to $56.4 million for the three
months ended May 31, 1999 primarily due to the Gilmore acquisition. Year to date
1999 revenue increased 26.9 percent to $146.3 million,  largely due to the Allen
and Gilmore acquisitions. Operating profit remained relatively unchanged at $4.4
million for the quarter and increased 24.3 percent to $11.1 million for the nine
months as increased  volumes and materials cost savings were partially offset by
gains realized in 1998 on the sale of idle equipment.

Corporate  expenses  were  lower  during  the three  months  ended May 31,  1999
compared  to  the  same  period  in  the  prior  year,  primarily  due to a gain
recognized  on the sale of a building  in the third  quarter of 1999.  Corporate
expenses during the nine month period approximated last year.

Net  interest  expense was $3.3  million and $8.2  million in the three and nine
months  ended May 31,  1999,  respectively,  compared  with $1.3  million of net
interest  expense and $1.1 million of net interest income for the three and nine
months ended May 31, 1998, respectively. The increase in net interest expense is
due to  lower  interest  income,  resulting  from  the  use  of  the  short-term
investments  generated  from  the  textile  rental  segment's  1997  divestiture
proceeds,  combined with higher interest expense from increased  borrowing.  The
increased  borrowing  is the result of the  issuance of $160 million in publicly
traded  notes  in the  second  quarter  of  1999  to  fund  acquisitions,  share
repurchases,  and internal growth. See "Financing  Activities" below for further
discussion.

The  provision  for income taxes was 37.2 percent of pretax income for the three
and nine months  ended May 31,  1999  compared  with 37.2  percent for the prior
third quarter and 37.1 percent for the prior year to date.

Liquidity and Capital Resources

Operating Activities

Operations  provided  cash of $115.5  million  during the first  nine  months of
fiscal 1999 and used cash of $1.6  million  during the nine months ended May 31,
1998. The increase in operating  cash flow is primarily due to improved  working
capital  management  in  the  lighting  equipment  and  chemical  segments.  The
remaining  improvement  relates to additional tax payments of $38.5 million made
during 1998 primarily  related to the 1997 textile  rental segment  divestitures
that are not repeated in current year results.

Investing Activities

Investing  activities  used cash of $108.0 million for the nine months ended May
31, 1999 compared with cash provided of $110.5  million in the nine months ended
May 31,  1998.  The cash flow in the first  three  quarters  of fiscal  1998 was
higher  because of the  liquidation  of  short-term  investments.  Additionally,
acquisition  spending in the first three  quarters of fiscal 1999 totaled  $62.9
million  compared to $39.4  million  during the  respective  prior year  period.
Current year  acquisition  spending was primarily  related to the September 1998
purchase  by  the  lighting  equipment  segment  of  the  assets  of  Hydrel,  a
manufacturer of architectural-grade light fixtures for landscape,  in-grade, and
underwater  applications;  the February 1999 purchase by the envelope segment of
Gilmore, an envelope manufacturer headquartered in Los Angeles,  California; and
the April  1999  purchase  by the  lighting  equipment  segment of  Peerless,  a
manufacturer of high performance  indirect/direct  suspended  lighting products.
The company  also made minor  acquisitions  related to the  chemical and textile
rental segments. Prior-year acquisition spending of $39.4 million was due to the
chemical  segment's  purchase of Pure Corporation,  a specialty chemical company
with its core  businesses in Indiana,  Pennsylvania,  and New York; the envelope
segment's   purchase   of   Allen   Envelope   Corporation,    a   single-plant,
Pennsylvania-based  envelope manufacturer serving markets in the Northeast;  and
performance payments associated with a 1997 chemical acquisition.

Capital  expenditures were $48.3 million in the first nine months of fiscal 1999
compared  with $56.8  million in the first nine months of fiscal  1998.  Capital
spending in the first three  quarters of fiscal 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
<PAGE>

Page 12

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.  Capital  spending  in the  first  three
quarters  of  fiscal  1998  consisted   primarily  of  facility  expansions  and
manufacturing process improvements in the lighting equipment segment, efficiency
improvements and replacements of processing equipment and information systems in
the textile  rental  segment,  and facility and  machinery  replacements  in the
envelope segment.  Capital  expenditures for fiscal 1999 are estimated to be $81
million.

Financing Activities

Cash  provided  by  financing  activities  was $33.7  million in the first three
quarters of fiscal 1999 compared  with cash used of $136.3  million in the first
three quarters of fiscal 1998.  Contributing to the change were net purchases of
treasury  stock  which were $38.3  million in the  current  year  versus  $145.2
million in the prior year.  During the first three  quarters of 1999 the company
repurchased approximately 1.2 million of its common shares.

In the second quarter, the company  successfully  completed the issuance of $160
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 short-term  borrowings,
with the remainder  available for general corporate  purposes  including working
capital   requirements,   capital  expenditures,   acquisitions,   repayment  of
outstanding indebtedness, and share repurchases. Dividend payments totaled $38.9
million,  or 95 cents per share,  compared with $39.8  million,  or 92 cents per
share,  for the prior-year  period.  On January 6, 1999,  the regular  quarterly
dividend  rate was  increased  3.2  percent to 32 cents per share,  or an annual
calendar year rate of $1.28 per share.

Management  believes the  company's  planned  level of  acquisition  and capital
spending and general operating cash requirements for the next twelve months will
be sufficiently  covered by current cash balances,  anticipated  cash flows from
operations,  available  funds  from  the  existing  five-year  revolving  credit
facility,  the  company's  active  shelf  registration,  complementary  lines of
credit,  and a new 364-day  revolving  credit  facility  which is expected to be
executed in late July 1999.

As  discussed in Note 8 to the  financial  statements,  the company  commenced a
tender  offer  for  the   outstanding   shares  of  Holophane  for  a  total  of
approximately  $450 million.  The company will initially finance the transaction
with short-term debt.

Environmental Matters

See  Note  6 to the  financial  statements  for a  discussion  of the  company's
environmental matters.

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 May 31, 1999, all areas of
the company had completed the first three phases and  implementation of the plan
was approximately 92 percent complete.  Management estimates that the total cost
to be incurred in connection with the Year 2000 Issue will range from $4 million
to $6 million, and substantially all mission critical systems are expected to be
in compliance prior to the end of calendar year 1999. 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 May
31,  1999,  the company had spent  approximately  $4.0  million on the Year 2000
Issue. The cost of the project is being funded through operating cash flows.

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 is currently completing a
contingency plan to address the potential for unforeseen  issues that may arise.
These contingency plans include 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.

Mr. George H. Gilmore
631 Blackthorn Road
Winnetka, Illinois   60093


Dear George:


         This  letter  will  confirm  the terms of your  employment  by National
Service Industries,  Inc. ("NSI") and NSI Services, L.P., effective June 1, 1999
(the "Effective  Date"). We are enthusiastic about your decision to join NSI and
look forward to working with you to build a bigger, stronger NSI.

         The terms of your employment, which are subject, of course, to approval
by our Executive  Resource and  Nominating  Committee and the Board of Directors
(or its  Executive  Committee)  and  satisfactory  completion  of  NSI's  normal
pre-employment screening procedures, will be as follows:

         1. Title and Duties - As Executive Vice President and Group  President,
you will be a senior  officer of NSI reporting to its Chief  Executive  Officer.
You will have  responsibility for NSI's Chemical Group,  National Linen Service,
and  AECO  operating  units  and any  additional  businesses  and  other  duties
consistent  with your  position  which may be assigned to you by NSI's CEO.  You
will also serve in the same capacity for NSI Services, L.P. (the "Partnership").
You  will  assume  the  duties  and  responsibilities  commensurate  with  those
positions,  which  will  include  service  to NSI,  the  Partnership,  and other
subsidiaries and partnerships of NSI and may receive compensation, benefits, and
other amounts from such entities,  the aggregate  amount of which will equal the
sums and benefits  specified herein.  You will devote  substantially all of your
working time and  attention to the business and affairs of NSI and the foregoing
entities.

         2. Base Salary - Your base salary will be  Thirty-seven  Thousand  Five
Hundred  Dollars  ($37,500)  per  month or the  equivalent  annual  rate of Four
Hundred Fifty  Thousand  Dollars  ($450,000),  subject to review for  increases.
Senior officer reviews at NSI are normally conducted for the April Board meeting
effective March 1.

         3. Annual  Incentive  Compensation  - You will  participate  in the NSI
Management  Compensation  and  Incentive  Plan (the  "AIP") for the fiscal  year
beginning  September  1,  1999  with a target  bonus  equal to 50% of your  base
salary.  You will  participate  in the AIP for the fiscal year ending August 31,
1999 on a pro rata basis for the period of your  employment  and will  receive a
bonus for the period of at least Seventy Five Thousand Dollars ($75,000).

                                                             EXHIBIT 10(iii)A(1)

         4. Long-Term  Achievement  Incentive Plan - You will receive a grant of
employee  stock options for fifty  thousand  (50,000)  shares of stock under our
current  long-term  incentive  plan upon your  arrival at NSI.  You will also be
entitled to  participate in the current  long-term  incentive plan on a prorated
basis for the number of months you are employed with NSI during the remainder of
the three-year  cycle ending August 31, 2000 and the remainder of the three-year
cycle ending August 31, 2001 based on the  performance of NSI's Chemical  Group,
National  Linen  Service,  and AECO  operating  units.  In addition,  subject to
approval by our  stockholders  at the January 2000 annual  meeting of additional
shares to be granted under our Long-Term  Achievement  Incentive  Plan, you will
participate in the Plan for the three-year cycle beginning  September 1, 1999 on
a comparable  basis with other senior  officers.  This Plan  provides for annual
grants of stock  options  and annual  "aspiration  awards"  having a total value
equal to 160% of salary at  commitment  (or  target)  level  performance.  Stock
options  represent 70% of total value (or 112% of salary) and aspiration  awards
represent 30% of total value (or 48% of salary) at commitment level performance.

                  Currently,  aspiration  awards  are  based on  achievement  of
cumulative  economic  profit  goals  over a  three-year  cycle  and are  payable
one-half in cash and one-half in NSI stock  following  completion of each cycle.
The form of payment may be changed under the new plan. The payout for aspiration
level  performance is equal to five times the value of the payout for commitment
level  performance  (or 240% of  salary).  Failure  to achieve  threshold  level
performance will result in no payout.

         5. Retirement Plans - Upon satisfying the eligibility requirements, you
will be eligible to participate in NSI's  tax-qualified  retirement  plans,  NSI
Pension  Plan C, and the NSI 401(k)  Plan for  Corporate  Office  Employees.  In
addition,  upon  employment,  you will become a participant in the  Supplemental
Retirement Plan for Executives of NSI (the "SERP"). Your benefits under the SERP
will be  determined  in the same manner as for other  executive  officers of NSI
participating in the plan (other than the Chief Executive Officer),  except that
you will be  credited  with  service  under  the SERP  for each  year of  actual
service.  You will become vested in your SERP benefit after  completing five (5)
years of  employment  with NSI and will be eligible for early  retirement at age
sixty (60).

         6. Medical,  Life Insurance,  and Other Employee Benefits - You will be
covered by, or eligible to participate in, the medical,  dental, life insurance,
disability,  deferred  compensation,  and other benefit programs  generally made
available by NSI to its executive  officers and their families,  including a car
allowance of Four Hundred  Dollars  ($400) per month.  We will reimburse you for
your  COBRA  expenses  until  you are  covered  under our  program.  You will be
eligible  to  participate  in  NSI's  financial  planning  program  and NSI will
reimburse  you for any  initiation  fees and monthly dues for  membership in the
Commerce Club.

         7.  Relocation  Expenses  -  NSI  will  pay  the  following  relocation
expenses:

(a)  your expenses for moving your household effects to Atlanta;

(b)  rent for an  apartment  and  storage of your  personal  effects in Atlanta,
     pending your move into your new home in Atlanta;

(c)  brokerage and closing  costs you incur in connection  with the sale of your
     home in Chicago and the purchase of a home in Atlanta;

(d)  reasonable  travel  expenses to and from  Chicago for you and your wife and
     children until you have moved your residence to Atlanta; and

(e) a  one-time  payment  of one  month's  salary  for  your  assistance  in the
relocation.

The foregoing  payments  will be "grossed up" so that, to the extent  reasonably
practicable,  they will represent your after-tax cost for covered  expenses.  In
addition to the foregoing,  we will assist you in obtaining a bridge loan should
you purchase a home in Atlanta before selling your home in Chicago and pay up to
two (2) points of any loan fees incurred for such purchase.

         8.  Employment  at  Will/Severance  Payment/Change  in  Control  - Your
employment  will be at will and may be  terminated  by either  NSI or you at any
time for any reason, with or without notice.  Except in the event of termination
in  connection  with a Change in  Control of NSI (as  defined  in the  Severance
Protection Agreement that will cover you), you will be entitled to the following
severance payment:

     o    If your  employment  is  terminated  on or before June 1, 2000 for any
          reason other than  voluntary  termination,  termination  upon death or
          Disability  (as defined  below),  or  termination by NSI for Cause (as
          defined  below),  you will  receive a  severance  payment  (payable in
          semi-monthly  installments)  equal to your then  current  salary for a
          period equal to the time from the date of termination  through June 1,
          2002. If your  employment  is terminated  after June 1, 2000 but on or
          before June 1, 2009 for any reason other than  voluntary  termination,
          termination upon death or Disability, or termination by NSI for Cause,
          you  will  receive  a  severance   payment  (payable  in  semi-monthly
          installments)  equal to your then  current  salary for a period of two
          (2) years.

                                                                         Page 21

     o    For purposes of entitlement to a severance benefit, "Cause" shall mean
          any act(s) on your part that  constitutes  fraud,  a felony  involving
          dishonesty,  a breach  of  fiduciary  duty,  or gross  malfeasance  or
          habitual neglect of your duties for NSI, and "Disability" shall mean a
          physical  or  mental   infirmity   which   impairs   your  ability  to
          substantially   perform  your  duties  as  Executive  Vice  President,
          Operations  of NSI  with or  without  reasonable  accommodation  for a
          period of one hundred  eighty (180)  consecutive  days. The NSI Board,
          based upon the information  provided to it, shall determine whether an
          act  constituting  Cause has occurred and whether you have  suffered a
          Disability.  In the case of  termination  for  Cause,  (i) you will be
          given  written  notice  of the  actions  constituting  Cause  at least
          fifteen  (15) days prior to any meeting of the Board of  Directors  of
          NSI at which your  termination is to be  considered;  (ii) you will be
          given  the  opportunity  to be  heard by the  Board;  and  (iii)  your
          termination  for Cause must be evidenced by a resolution  adopted by a
          majority of the Board.

In the event of  termination  by you "for good reason" (as defined below) during
the time  periods  described  above,  you  will be  entitled  to the  applicable
severance  payments  described above.  For purposes of this Agreement,  the term
"good   reason"   means:   a)  any  material   diminution  in  your  duties  and
responsibilities as Executive Vice President and Group President or authority or
title; b) any reduction in your base salary to less than  $400,000.00 per annum;
c) any  reduction in the target  amount of your annual bonus to less than 50% of
your salary,  which reduction is not applicable to other senior officers of NSI;
and d) your being  required  to relocate to an office more than fifty miles from
NSI's current office.

With respect to Change in Control situations, you will be covered by a Severance
Protection  Agreement with the same  provisions as are applicable to NSI's other
executive officers. In the event of your termination in connection with a Change
in  Control  that  entitles  you to  benefits  under  the  Severance  Protection
Agreement,  you will receive the greater of the  payments and benefits  provided
under  the  Severance  Protection  Agreement  (after  consideration  of any  tax
penalties) or the severance payments described above.

         9.  Relocation  of  Residence  to  Atlanta  - You  will  relocate  your
residence  to Atlanta and  complete the move of your family on or before July 1,
2000.

         The base salary, annual incentive,  long-term incentives,  nonqualified
retirement benefits, and any severance payments will be structured to ensure the
tax deductibility to NSI of the payments and benefits under the Internal Revenue
Code  of  1986,  including  Code  Section  162(m).  We  can  provide  additional
information on these issues if you so desire.

         We will prepare a SERP provision and Severance  Protection Agreement to
evidence the arrangements set forth in this letter.

         We are  delighted you are joining NSI and we look forward to a long and
mutually  satisfactory  relationship.   This  letter  outlines  your  employment
relationship with NSI; if you agree with the employment terms as outlined above,
please sign and date both copies of this letter agreement and return one copy to
me at your earliest convenience.

                                                     Sincerely,



                                                 /s/ James S. Balloun

                        INCENTIVE STOCK OPTION AGREEMENT
              FOR EXECUTIVE OFFICERS AND OPERATING UNIT PRESIDENTS




     THIS  AGREEMENT,  made as of the 1st day of June,  1999 (the "Grant Date"),
between  National  Service  Industries,   Inc.,  a  Delaware   corporation  (the
"Company"), and George H. Gilmore, Jr. (the "Optionee").

     WHEREAS,  the Company has adopted the  National  Service  Industries,  Inc.
Long-Term Achievement Incentive Plan (the "Plan") in order to provide additional
incentive  to  certain  officers  and  key  employees  of the  Company  and  its
Subsidiaries; and

     WHEREAS,  the  Optionee  performs  services  for the  Company or one of its
Subsidiaries; and

     WHEREAS,  the  Committee  responsible  for  administration  of the Plan has
determined to grant the Option to the Optionee as provided herein.

     NOW, THEREFORE, the parties hereto agree as follows:

     1.   Grant of Option.

     1.1 The Company  hereby  grants to the  Optionee  the right and option (the
"Option")  to purchase  all or any part of an  aggregate  of 10,844 whole Shares
subject to, and in accordance  with,  the terms and conditions set forth in this
Agreement.

     1.2 The Option is intended to qualify as an Incentive  Stock Option  within
the  meaning of  Section  422 of the Code and shall be so  construed;  provided,
however,   that  nothing  in  this   Agreement   shall  be   interpreted   as  a
representation,  guarantee or other  undertaking on the part of the Company that
the Option is or will be determined  to be an Incentive  Stock Option within the
meaning of Section 422 of the Code.  To the extent this Option is not treated as
an Incentive Stock Option, it will be treated as a Nonqualified Stock Option.

     1.3 This Agreement  shall be construed in accordance  and consistent  with,
and  subject  to,  the  provisions  of the Plan  (the  provisions  of which  are
incorporated  herein by reference) and, except as otherwise  expressly set forth
herein,  the  capitalized  terms  used in this  Agreement  shall  have  the same
definitions as set forth in the Plan.

     2. Purchase Price.

     The price at which the Optionee  shall be entitled to purchase  Shares upon
the exercise of the Option shall be $36.875 per Share.

     3. Duration of Option.

     The Option shall be  exercisable  to the extent and in the manner  provided
herein for a period of ten (10) years from the Grant Date (the "Exercise Term");
provided,  however,  that the Option may be earlier  terminated  as  provided in
Section 6 hereof.

     4. Exercisability of Option.

     Unless  otherwise  provided in this Agreement or the Plan, the Option shall
entitle the Optionee to  purchase,  in whole at any time or in part from time to
time,  25% of the  total  number  of  Shares  covered  by the  Option  after the
expiration  of one (1) year from the  Grant  Date and an  additional  25% of the
total number of Shares covered by the Option on each of the second,  third,  and
fourth  anniversaries  of the Grant Date.  Each such right of purchase  shall be
cumulative and shall continue,  unless sooner  exercised or terminated as herein
provided during the remaining period of the Exercise Term.

     5. Manner of Exercise and Payment.

     5.1 Subject to the terms and conditions of this Agreement and the Plan, the
Option may be  exercised by delivery of written  notice to the  Company,  at its
principal  executive  office.  Such  notice  shall  state that the  Optionee  is
electing to exercise the Option and the number of Shares in respect of which the
Option  is being  exercised  and  shall  be  signed  by the  person  or  persons
exercising  the Option.  If requested by the  Committee,  such person or persons
shall (i)  deliver  this  Agreement  to the  Secretary  of the Company who shall
endorse thereon a notation of such exercise and (ii) provide  satisfactory proof
as to the right of such person or persons to exercise the Option.

     5.2 The notice of exercise described in Section 5.1 shall be accompanied by
the full  purchase  price for the Shares in respect of which the Option is being
exercised,  in cash, by check or by transferring  Shares to the Company having a
Fair Market Value on the day  preceding  the date of exercise  equal to the cash
amount for which such Shares are substituted.

     5.3 Upon  receipt of notice of exercise  and full payment for the Shares in
respect of which the Option is being  exercised,  the Company shall,  subject to
Section  17 of the Plan,  take such  action as may be  necessary  to effect  the
transfer to the  Optionee of the number of Shares as to which such  exercise was
effective.

     5.4 The Optionee shall not be deemed to be the holder of, or to have any of
the rights of a holder with  respect to any Shares  subject to the Option  until
(i) the Option shall have been exercised pursuant to the terms of this Agreement
and the  Optionee  shall  have paid the full  purchase  price for the  number of
Shares in respect of which the Option was exercised, (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,
whereupon the Optionee  shall have full voting and other  ownership  rights with
respect to such Shares.

     6. Termination of Employment.

     6.1 In General.

     If the  employment  of the Optionee  with the Company and its  Subsidiaries
shall terminate for any reason, other than for the reasons set forth in Sections
6.2 and 7.2 below,  the Option shall continue to be  exercisable  (to the extent
the Option was vested and exercisable on the date of the Optionee's  termination
of  employment)  at any time  within  three  (3)  months  after the date of such
termination of employment,  but in no event after the expiration of the Exercise
Term.

     6.2 Termination of Employment Due to Death, Disability or Retirement.

     If the Optionee's termination of employment is due to Death,  Disability or
Retirement  (termination  on  or  after  age  65),  or  if  Optionee  terminates
employment after age 55, the following shall apply:

          (a)  Termination  Due To Death.  In the event the Optionee  dies while
               actively employed,  all vested Options at the date of death shall
               remain  exercisable  at any time prior to the  expiration  of the
               Exercise  Term by (A)  such  person(s)  that  have  acquired  the
               Optionee's  rights  under such  Options by will or by the laws of
               descent and  distribution,  or (B) if no such person described in
               (A)  exists,  the  Optionee's  estate  or  representative  of the
               Optionee's estate. All Options that are not vested as of the date
               of death shall be immediately forfeited.

          (b)  Termination  by  Disability.  In the event the  employment of the
               Optionee  is  terminated  by reason  of  Disability,  all  vested
               Options  as of the date the  Committee  determines  the  Optionee
               terminated  for Disability  shall remain  exercisable at any time
               prior to the  expiration of the Exercise  Term.  All Options that
               are not vested as of the date of termination for Disability shall
               be immediately forfeited.

          (c)  Termination  by  Retirement.  In the event the  employment of the
               Optionee is terminated by reason of  Retirement,  the  Optionee's
               Options shall  continue to vest in  accordance  with the original
               schedule  (just as if the  Optionee had  remained  employed)  and
               shall remain  exercisable  at any time prior to the expiration of
               the lesser of five years or the  remaining  Exercise  Term of the
               Options.  In the event of the Optionee's death after  Retirement,
               the  Options  shall  continue  to  vest  and  be  exercisable  in
               accordance  with this subsection (c) as if the Optionee had lived
               and the Options shall be exercisable by the persons  described in
               (a) above.

          (d)  Termination  After  Attaining Age 55. If the Optionee  terminates
               employment  (other than as a result of death or Disability) after
               attaining  age 55 but  prior  to age  65,  unless  the  Committee
               determines  otherwise  at  the  time  of  such  termination,  the
               Optionee's  Options shall continue to vest in accordance with the
               original schedule (just as if the Optionee had remained employed)
               and shall remain  exercisable at any time prior to the expiration
               of the lesser of five years or the remaining Exercise Term of the
               Options.  In the event of the Optionee's death after  Retirement,
               the  Options  shall  continue  to  vest  and  be  exercisable  in
               accordance  with this subsection (d) as if the Optionee had lived
               and the Options shall be exercisable by the persons  described in
               (a) above.

     7. Effect of Change in Control.

     7.1  Notwithstanding  anything contained to the contrary in this Agreement,
in the event of a Change in Control, (i) the Option shall become immediately and
fully  exercisable,  and (ii) the Optionee  will be  permitted to surrender  for
cancellation within sixty (60) days after such Change in Control,  the Option or
any  portion of the Option to the extent  not yet  exercised,  and the  Optionee
shall be entitled to receive  immediately  a cash  payment in an amount equal to
the excess,  if any, of (A) the Fair Market Value, at the time of surrender,  of
the Shares subject to the Option or portion  thereof  surrendered,  over (B) the
aggregate  purchase price for such Shares under the Option;  provided,  however,
that if the Option  was  granted  within  six (6) months  prior to the Change in
Control and the Optionee may be subject to liability  under Section 16(b) of the
Exchange  Act, the Optionee  shall be entitled to surrender  the Option,  or any
portion  of the  Option,  for  cancellation  during  the sixty  (60) day  period
following  the  expiration  of six (6) months from the Grant Date and to receive
the amount described above with respect to such surrender for cancellation.

     7.2 If the  employment of the Optionee is  terminated  within two (2) years

Term.

any way  with  the  right  of the  Company  or a  Subsidiary  to  terminate  the
Optionee's employment at any time.

     10. Adjustments.

     In the  event  of a  Change  in  Capitalization,  the  Committee  may  make
appropriate  adjustments  to the  number  and class of Shares or other  stock or
securities subject to the Option and the purchase price for such Shares or other
stock or securities. The Committee's adjustment shall be made in accordance with

cash to the  Optionee an amount equal to the  federal,  state,  and local income
taxes  and  other  amounts  as  may be  required  by  law  to be  withheld  (the
"Withholding  Taxes") with respect to the Option. If the Optionee is entitled to
receive  Shares  upon  exercise  of the  Option,  the  Optionee  shall  pay  the
Withholding  Taxes (if any) to the Company in cash prior to the issuance of such
Shares.  In  satisfaction  of the  Withholding  Taxes,  the  Optionee may make a
written election (the "Tax Election"),  which may be accepted or rejected in the
discretion of the Committee,  to have withheld a portion of the Shares  issuable
to him or her upon exercise of the Option, having an aggregate Fair Market Value
equal to the withholding Taxes, provided that, if the Optionee may be subject to
liability under Section 16(b) of the Exchange Act, the election must comply with
the requirements applicable to Share transactions by such Optionees.

     12.2 If the  Optionee  makes a  disposition,  within the meaning of Section
424(c)  of the Code and  regulations  promulgated  thereunder,  of any  Share or
Shares  issued to him pursuant to his exercise of the Option within the two-year
period  commencing on the day after the Grant Date or within the one-year period
commencing  on the day after the date of transfer of such Share or Shares to the
Optionee pursuant to such exercise,  the Optionee shall, within ten (10) days of
such disposition,  notify the Company thereof,  by delivery of written notice to
the Company at its principal  executive office,  and immediately  deliver to the
Company the amount of Withholding Taxes.

jurisdiction  to be  unenforceable  or invalid  for any  reason,  the  remaining
provisions  of this  Agreement  shall not be affected by such  holding and shall

any way relate to, the  interpretation,  construction,  or  application  of this
Agreement shall be determined by the Committee. Any determination made hereunder

                       NONQUALIFIED STOCK OPTION AGREEMENT
              FOR EXECUTIVE OFFICERS AND OPERATING UNIT PRESIDENTS




         THIS AGREEMENT, made as of the 1st day of June, 1999(the "Grant Date"),
between  National  Service  Industries,   Inc.,  a  Delaware   corporation  (the
"Company"), and George H. Gilmore, Jr. (the "Optionee").

         WHEREAS, the Company has adopted the National Service Industries,  Inc.
Long-Term Achievement Incentive Plan (the "Plan") in order to provide additional
incentive  to  certain  officers  and  key  employees  of the  Company  and  its
Subsidiaries; and

         WHEREAS, the Optionee performs services for the  Company and/or one  of
 its Subsidiaries; and

         WHEREAS,  the Committee  responsible for administration of the Plan has
determined to grant the Option to the Optionee as provided herein.

         NOW, THEREFORE, the parties hereto agree as follows:

         1.       Grant of Option.

                  1.1 The Company  hereby  grants to the  Optionee the right and
option (the  "Option")  to purchase  all or any part of an  aggregate  of 39,156
whole Shares  subject to, and in accordance  with,  the terms and conditions set
forth in this Agreement.

                  1.2      The Option is not intended to qualify as an Incentive
Stock Option within the meaning of Section 422 of the Code.

                  1.3  This  Agreement  shall be  construed  in  accordance  and
consistent  with, and subject to, the provisions of the Plan (the  provisions of
which are incorporated  herein by reference) and, except as otherwise  expressly
set forth herein,  the  capitalized  terms used in this Agreement shall have the
same definitions as set forth in the Plan.

         2.       Purchase Price.

                  The price at which the Optionee shall  be entitled to purchase
Shares upon the exercise of the Option shall be $36.875 per Share.

         3.       Duration of Option.

                  The  Option  shall be  exercisable  to the  extent  and in the

"Exercise Term");  provided,  however, that the Option may be earlier terminated
as provided in Section 6 hereof.

         4.       Exercisability of Option.

                  Unless  otherwise  provided in this Agreement or the Plan, the
Option shall  entitle the Optionee to purchase,  in whole at any time or in part
from time to time, 25% of the total number of Shares covered by the Option after
the  expiration of one (1) year from the Grant Date and an additional 25% of the
total number of Shares covered by the Option on each of the second,  third,  and
fourth anniversaries of the Grant Date, and each such right of purchase shall be
cumulative and shall continue,  unless sooner  exercised or terminated as herein
provided during the remaining period of the Exercise Term.

         5.       Manner of Exercise and Payment.

                  5.1 Subject to the terms and  conditions of this Agreement and
the Plan,  the Option may be  exercised  by  delivery  of written  notice to the
Company,  at its principal  executive  office.  Such notice shall state that the
Optionee is electing to exercise  the Option and the number of Shares in respect
of which the  Option  is being  exercised  and shall be signed by the  person or
persons  exercising the Option.  If requested by the  Committee,  such person or
persons  shall (i) deliver this  Agreement  to the  Secretary of the Company who
shall endorse thereon a notation of such exercise and (ii) provide  satisfactory
proof as to the right of such person or persons to exercise the Option.

                  5.2 The notice of exercise  described  in Section 5.1 shall be
accompanied  by the full  purchase  price for the Shares in respect of which the
Option is being exercised,  in cash, by check, or by transferring  Shares to the
Company  having a Fair Market  Value on the day  preceding  the date of exercise
equal to the cash amount for which such Shares are substituted.

                  5.3 Upon  receipt of notice of exercise  and full  payment for
the Shares in respect of which the Option is being exercised, the Company shall,
subject to  Section  17 of the Plan,  take such  action as may be  necessary  to
effect the  transfer  to the  Optionee  of the number of Shares as to which such
exercise was effective.

                  5.4 The  Optionee  shall not be deemed to be the holder of, or
to have any of the rights of a holder with respect to any Shares  subject to the
Option until (i) the Option shall have been  exercised  pursuant to the terms of
this  Agreement and the Optionee shall have paid the full purchase price for the
number of Shares in respect of which the Option was exercised,  (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,  whereupon  the  Optionee  shall  have  full  voting  and other
ownership rights with respect to such Shares.

         6.       Termination of Employment.

                  6.1      In General.

                           If the  employment of the Optionee  with the  Company
and its Subsidiaries shall terminate for any reason,  other than for the reasons
set forth in  Sections  6.2 and 7.2  below,  the  Option  shall  continue  to be
exercisable  (to the extent the Option was vested and exercisable on the date of
the  Optionee's  termination  of employment) at any time within three (3) months
after the date of such  termination  of  employment,  but in no event  after the
expiration of the Exercise Term.

                  6.2      Termination of Employment Due to Death, Disability or
                           Retirement.

                           If the Optionee's termination of  employment  is  due
to Death,  Disability  or  Retirement  (termination  on or after age 65),  or if
Optionee terminates employment after age 55, the following shall apply:

         (a)      Termination Due To Death. In the event the Optionee dies while
                  actively  employed,  all  vested  Options at the date of death
                  shall remain  exercisable  at any time prior to the expiration
                  of the Exercise Term by (A) a Permitted Transferee (as defined
                  in  Section  8 below),  if any,  or such  person(s)  that have
                  acquired the  Optionee's  rights under such Options by will or
                  by the laws of  descent  and  distribution,  or (B) if no such
                  person  described  in (A)  exists,  the  Optionee's  estate or
                  representative of the Optionee's  estate. All Options that are
                  not  vested  as of the  date of  death  shall  be  immediately
                  forfeited.

         (b)      Termination by Disability.  In the event the employment of the
                  Optionee is  terminated  by reason of  Disability,  all vested
                  Options as of the date the Committee  determines  the Optionee
                  terminated for Disability shall remain exercisable at any time
                  prior to the expiration of the Exercise Term. All Options that
                  are not vested as of the date of  termination  for  Disability
                  shall be immediately forfeited.

         (c)      Termination by Retirement.  In the event the employment of the
                  Optionee is terminated by reason of Retirement, the Optionee's
                  Options shall continue to vest in accordance with the original
                  schedule  (just as if the Optionee had remained  employed) and
                  shall remain  exercisable  at any time prior to the expiration
                  of the lesser of five years or the remaining  Exercise Term of
                  the  Options.  In the  event  of the  Optionee's  death  after
                  Retirement,   the  Options  shall  continue  to  vest  and  be
                  exercisable in accordance  with this  subsection (c) as if the
                  Optionee had lived and the Options shall be exercisable by the
                  persons described in (a) above.

          (d)     Termination After Attaining Age 55. If the Optionee terminates
                  employment  (other  than as  a result  of death or Disability)
                  after  attaining  age 55 but  prior  to  age  65,  unless  the
                  Committee  determines   otherwise  at   the   time   of   such
                  termination,  the Optionee's Options shall continue to vest in
                  accordance with the original schedule (just as if the Optionee
                  had remained employed)and shall remain exercisable at any time
                  prior to the  expiration of the lesser of  five years  or  the
                  remaining Exercise Term of the Options.  In  the  event of the
                  Optionee's   death  after   Retirement,  the   Options   shall
                  continue  to  vest  and  be  exercisable  in  accordance  with
                  this  subsection  (d)  as  if  the  Optionee had lived and the
                  Options shall be exercisable by the persons  described  in (a)
                  above.

         7.       Effect of Change in Control.

                  7.1 Notwithstanding anything contained to the contrary in this
Agreement,  in the event of a Change in  Control,  (i) the Option  shall  become
immediately  and fully  exercisable,  and (ii) the Optionee will be permitted to
surrender for cancellation  within sixty (60) days after such Change in Control,
the Option or any portion of the Option to the extent not yet exercised, and the
Optionee  shall be entitled to receive  immediately  a cash payment in an amount
equal to the excess,  if any, of (A) the greater of (x) the Fair Market Value on
the date preceding the date of surrender, of the shares subject to the Option or
portion of the Option surrendered,  or (y) the Adjusted Fair Market Value of the
Shares  subject  to the  Option or  portion  thereof  surrendered,  over (B) the
aggregate  purchase price for such Shares under the Option;  provided,  however,
that if the Option  was  granted  within  six (6) months  prior to the Change in
Control and the Optionee may be subject to liability  under Section 16(b) of the
Exchange  Act, the Optionee  shall be entitled to surrender  the Option,  or any
portion  of the  Option,  for  cancellation  during  the sixty  (60) day  period
following  the  expiration  of six (6) months from the Grant Date and to receive
the amount described above with respect to such surrender for cancellation.

                  7.2 If the employment of the Optionee is terminated within two
(2) years following a Change in Control, all vested Options shall continue to be
exercisable  at any  time  within  three  (3)  years  after  the  date  of  such
termination  of  employment,  but in no event after  expiration  of the Exercise
Term.

         8.       Nontransferability.

                  The Option shall not be transferable  other than by will or by
the laws of descent and distribution.  Notwithstanding the foregoing, the Option
may be  transferred,  in whole or in part,  without  consideration,  by  written
instrument signed by the Optionee, to any members of the immediate family of the
Optionee (i.e., spouse, children, and grandchildren), any trusts for the benefit
of such family members or any  partnerships  whose only partners are such family
members (the "Permitted Transferees"). Appropriate evidence of any such transfer
to the Permitted  Transferees shall be delivered to the Company at its principal
executive  office.  If all or part of the Option is  transferred  to a Permitted
Transferee,  the Permitted Transferee's rights hereunder shall be subject to the
same  restrictions  and limitations  with respect to the Option as the Optionee.
During the lifetime of the Optionee, the Option shall be exercisable only by the
Optionee, or if applicable, by the Permitted Transferees.

         9.       No Right to Continued Employment.

                  Nothing in this  Agreement or the Plan shall be interpreted or
construed to confer upon the Optionee any right with respect to  continuance  of
employment by the Company or a Subsidiary,  nor shall this Agreement or the Plan
interfere in any way with the right of the Company or a Subsidiary  to terminate
the Optionee's employment at any time.

         10.      Adjustments.

                  In the event of a Change in Capitalization,  the Committee may
make appropriate adjustments to the number and class of Shares or other stock or
securities subject to the Option and the purchase price for such Shares or other
stock or securities. The Committee's adjustment shall be made in accordance with
the  provisions  of  Section  11 of the Plan and shall be  effective  and final,
binding, and conclusive for all purposes of the Plan and this Agreement.

         11.      Terminating Events.

                  Subject to Section 7 hereof,  upon the  effective  date of (i)
the liquidation or dissolution of the Company or (ii) a merger or  consolidation
of the  Company  (a  "Transaction"),  the  Option  shall  continue  in effect in
accordance  with its terms and the  Optionee  shall be  entitled  to  receive in
respect of all Shares  subject to the Option,  upon exercise of the Option,  the
same  number  and  kind  of  stock,   securities,   cash,  property,   or  other
consideration  that  each  holder of  Shares  was  entitled  to  receive  in the
Transaction.

         12.      Withholding of Taxes.

                  The   Company   shall  have  the  right  to  deduct  from  any
distribution of cash to the Optionee an amount equal to the federal,  state, and
local  income  taxes and other  amounts as may be required by law to be withheld
(the  "Withholding  Taxes")  with  respect to the  Option.  If the  Optionee  is

equal to the withholding Taxes, provided that, if the Optionee may be subject to
liability under Section 16(b) of the Exchange Act, the election must comply with
the requirements applicable to Share transactions by such Optionees.

                ASPIRATION ACHIEVEMENT INCENTIVE AWARD AGREEMENT
                FOR EXECUTIVE VICE PRESIDENT AND GROUP PRESIDENT


     THIS  AGREEMENT,  made as of the 1st day of June,  1999 (the "Grant Date"),
between National Service  Industries,  Inc., a Delaware  corporation ("NSI") and
NSI SERVICES,  L.P. (GA), a Subsidiary of NSI  (together,  the  "Company"),  and
GEORGE H. GILMORE, JR. (the "Grantee").


     WHEREAS,  NSI has adopted the National Service  Industries,  Inc. Long-Term
Achievement   Incentive  Plan  (the  "Plan")  in  order  to  provide  additional
incentives to certain  officers and key  employees of NSI and its  Subsidiaries;
and

     WHEREAS, the Grantee, as an executive of the  above-referenced  Subsidiary,
performs  services with respect to the CHEMICAL  GROUP,  NATIONAL LINEN SERVICE,
AND AECO operations of the Company (the "Operations"); and


     WHEREAS,  the  Committee  responsible  for  administration  of the Plan has
determined to grant to the Grantee an Aspiration  Achievement Incentive Award as
provided herein.


     NOW, THEREFORE, the parties hereto agree as follows:


     1. Grant of Aspiration Award.


     1.1 The  Company  hereby  grants to the Grantee an  Aspiration  Achievement
Incentive  Award (the  "Award"),  which has a value  determined  as  provided in
Section  2 below  based  upon  the  performance  of the  Operations  during  the
Performance  Cycle from September 1, 1997 to August 31, 2000. As provided in the
Plan,  Grantee's  right to  payment of this Award is  dependent  upon  Grantee's
continued  employment in Grantee's  current  position with the Company,  or in a
position with  responsibilities  of  substantially  similar value to the Company
during the remainder of the Performance  Cycle.  Under certain  circumstances as
described below,  Grantee may be entitled to receive payment for some portion of
the Award if Grantee's employment terminates prior to the end of the Performance
Cycle.


     1.2 The  Grantee  hereby  acknowledges  receipt  of a copy of the  Plan and
agrees to be bound by all the terms and provisions thereof. This Agreement shall
be construed in accordance with, and subject to, the provisions of the Plan (the
provisions  of which  are  hereby  incorporated  by  reference)  and,  except as
otherwise  expressly  set  forth  herein,  the  capitalized  terms  used in this
Agreement shall have the same definitions as set forth in the Plan.


     2. Performance Measure and Performance Levels.
<PAGE>
                                                                         Page 37
                                                             EXHIBIT 10(iii)A(6)


     The Committee has  established the  performance  measure (the  "Performance
Measure"),  and award and  performance  levels set forth in  Appendix A attached
hereto.  The chart in Appendix A specifies a Commitment  performance  level,  at
which the Commitment Level Award will be paid, an Aspiration  performance level,
at or above  which an  Aspiration  Level  Award  will be paid,  and a  threshold
performance  level,  at which a minimum  incentive  award will be paid and below
which no award  will be paid.  For each  level of  performance  at or above  the
threshold  performance level through the Aspiration  performance level,  Grantee
will receive an award  determined in accordance  with the chart and formulae set
forth in Appendix A. The terms used in determining the  Performance  Measure are
defined in Appendix B.


     3. Determination of Aspiration Award.


     3.1  Determination  Notice.  Subject to Section  3.2, as soon as  practical
following the last day of the Performance  Cycle,  the Committee will determine,
in  accordance  with  Section  7(c) of the Plan,  the  performance  level of the
Operations  with respect to the Performance  Measure for the Performance  Cycle.
The  Committee  may in  determining  the  performance  level with respect to the
Performance Measure adjust the Operations' financial results for the Performance
Cycle to  exclude  the  effect of  unusual  charges  or income  items  which are
distortive of financial results for the Performance  Cycle;  provided,  that, in
determining  financial  results,  items whose exclusion from  consideration will
increase the performance  level of the Operations  shall only have their effects
excluded if they  constitute  "extraordinary  items"  under  generally  accepted
accounting principles and all such items shall be excluded.  The Committee shall
also adjust the performance  calculations to exclude the unanticipated effect on
financial results of changes in the Code, or other tax laws, and the regulations
thereunder.  The Committee shall also exclude from  consideration  the effect on
financial  performance of each of the following events or items where the result
of excluding the particular  event or item is to increase the performance  level
of the Operations:  (i) an acquisition or a divestiture  involving more than $10
million  in net  worth or $25  million  in  business  revenues;  (ii) an  equity
restructuring  involving more than $1 million;  (iii) asset  impairment  charges
involving more than $1 million and  restructuring  costs  involving more than $1
million  associated  with facility  closings or reduction in employment  levels;
(iv) changes in accounting  treatment or rules  involving  more than $1 million.
The Committee may decrease the amount of the Award otherwise  payable to Grantee
if,  in the  Committee's  view,  such  adjustment  is  necessary  or  desirable,
regardless of the extent to which the Performance Measure has been achieved. The
Committee may establish  such  guidelines and procedures for reducing the amount
of an Award as it deems appropriate.


     The Company will notify the Grantee (or the executors or  administrators of
the Grantee's  estate,  if applicable)  of the  Committee's  determination  (the
"Determination  Notice"). The Determination Notice shall specify the performance
level  of the  Operations  with  respect  to the  Performance  Measure  for  the
Performance  Cycle and the amount of Award (if any)  Grantee will be entitled to
receive. Unless the Committee determines otherwise at the time the Award is paid
and except as otherwise provided in the event of a Change in Control, the amount
Grantee is entitled  to receive  will be paid  one-half in cash and  one-half in
Shares.  The Shares will be valued at their Fair Market Value as of the last day
of the  Performance  Cycle.  Except  in the case of a  Change  in  Control,  the
Committee may, in its discretion,  attach restrictions,  terms and conditions to
the Shares issued as part of the Award.


     3.2 Significant  Events Involving the Operations.  If, during a Performance
Cycle,  NSI  consummates an acquisition or disposition  involving the Operations
that (i) involves assets whose value equals or exceeds 20% of the total value of
the  Operations'  assets,  (ii) represents a part of the business whose revenues
equal or exceed 20% of the total of the Operations'  revenues, or (iii) causes a
material restructuring of the Operations, the following rules shall apply:

<PAGE>
Page 38
                                                             EXHIBIT 10(iii)A(6)


     (a)  If the  transaction  is  consummated  during  the  first  year  of the
Performance  Cycle, the Performance  Cycle and the Grantee's  outstanding  Award
will be terminated with no payout and a new Performance  Cycle  containing a new
Award will be started.


     (b)  If  the  transaction  is  consummated  after  the  first  year  of the
Performance Cycle, the Performance Cycle will end and the outstanding Award will
be determined and paid at the Operations' actual performance level to such date,
taking into account the adjustments  provided for in Section 3.1 above and using
prorated performance levels of the Performance Measure to reflect the portion of
the  Performance  Cycle that had elapsed as of the date of  consummation  of the
acquisition  or  disposition.  Payment  of the  Award  will  be  made as soon as
practical  after it is determined.  A new  Performance  Cycle will be started to
cover the period remaining in the initial  Performance  Cycle or, if that result
is not practical,  the Committee will make an appropriate  adjustment to reflect
the premature termination of the initial Performance Cycle.


     If,  during  a  Performance   Cycle,  NSI  consummates  an  acquisition  or
disposition  that is not covered by the special  provisions of this Section 3.2,
the financial  effects of such  acquisition or  disposition  shall be handled as
provided in Section 3.1.


     Any actions  under this Section 3.2 shall be taken in  accordance  with the
requirements of Code Section 162(m) and the regulations thereunder.


     4. Termination of Employment.


     4.1 In General.  Except as provided in Sections 4.2, 4.3 and 4.4 below,  in
the event that a Grantee's employment terminates during a Performance Cycle, all
unearned Aspiration Awards shall be immediately forfeited by the Grantee.


     4.2 Termination of Employment Due to Death, Disability,  or Retirement.  In
the  event  the  employment  of a Grantee  is  terminated  by reason of death or
Disability  during a  Performance  Cycle,  the  Grantee  shall be  entitled to a
prorated payout with respect to the unearned Award. The prorated payout shall be
determined by the  Committee  based upon the length of time that the Grantee was
actively  employed during the  Performance  Cycle relative to the full length of
the Performance Cycle;  provided,  that payment shall only be made to the extent
at the end of the Performance  Cycle the Award would have been earned based upon
the performance  level achieved for the  Performance  Cycle (taking into account
the  adjustment  provisions  and other rules in Section 3 above);  and provided,
further,  that the performance level used to determine the prorated award cannot
exceed 200% of the Commitment performance level.
<PAGE>
                                                                         Page 39
                                                             EXHIBIT 10(iii)A(6)

     In the event of Grantee's  Retirement  (on or after age 65), the full Award
shall  continue to be eligible for payout at the end of the  Performance  Cycle,
just as if Grantee had remained  employed for the  remainder of the  Performance
Cycle  (including if the Grantee dies after Retirement but before the end of the
Performance  Cycle).  At the end of the Performance  Cycle,  the Committee shall
make its determination in the same manner as provided in Section 3.


     Payment  of earned  Awards to Grantee  in the event of  termination  due to
death,  Disability,  or Retirement shall be made at the same time payments would
be  made  to  Grantee  if  Grantee  did  not  terminate  employment  during  the
Performance Cycle.


     4.3 Change In Control.  Notwithstanding  anything in this  Agreement to the
contrary,  if a Change in Control occurs during the Performance  Cycle, then the
Grantee's Award shall be determined for the  Performance  Cycle then in progress
as  though  the  Performance  Cycle  had  ended as of the date of the  Change in
Control and the outstanding  Award will be paid at the Commitment Level Award or
the actual  performance  level to such date (using,  for such purpose,  prorated
performance  levels of the  Performance  Measure to reflect  the  portion of the
Performance  Cycle that has  elapsed  as of the date of the Change in  Control),
whichever provides the greater payment.  The Award determined in accordance with
the  preceding  sentence  shall be fully vested and payable  immediately  to the
Grantee.  The  Committee  shall  determine  the  amount of the Award  under this
Section 4.3, subject to the terms of this section, and no downward adjustment of
the Award which would result in reduction of the Award by more than 50% shall be
permitted.  The Award will be paid in full in cash, unless the Grantee elects to
receive one-half of the Award in Shares.  For purposes of determining the number
of Shares to be paid to a Grantee  under this Section 4.3, the Fair Market Value
of a Share shall be determined by taking the average closing price per share for
the last  twenty  (20)  trading  days  prior to the  commencement  of the offer,
transaction or other event which resulted in a Change in Control.


     4.4  Termination  Without  Cause.  In the  event  Grantee's  employment  is
terminated  by the  Company  without  Cause  more  than one (1) year  after  the
commencement  of the  Performance  Cycle and prior to the end of the Performance
Cycle,  the Grantee  shall be  entitled to a prorated  payout of the Award based
upon the  length of time that the  Grantee  was  actively  employed  during  the
Performance  Cycle  relative  to  the  full  length  of the  Performance  Cycle;
provided,  that  payment  shall  be made  only to the  extent  at the end of the
Performance  Cycle the Award would have been earned  based upon the  performance
level achieved during the Performance  Cycle (taking into account the adjustment
provisions and other rules in Section 3 above); and provided,  further, that the
performance level used to determine the prorated award cannot exceed 200% of the
Commitment  performance level. Payment shall be made to Grantee at the same time
as if Grantee had not terminated employment during the Performance Cycle


     5. No Right to Continued Employment.


     Nothing in this  Agreement or the Plan shall be  interpreted to confer upon
the Grantee any rights with respect to continuance of employment by the Company,
nor shall this  Agreement or the Plan interfere in any way with the right of the
Company to terminate the Grantee's employment at any time.

     6. Nonassignment.


     The Grantee shall not have the right to assign, alienate,  pledge, transfer
or  encumber  any  amounts  due  Grantee  hereunder,  and any attempt to assign,
alienate,  pledge,  transfer,  or encumber Grantee's rights or benefits shall be
null and void and not recognized by the Plan or the Company.


     7. Modification of Agreement.


     This Agreement may be modified,  amended,  suspended or terminated, and any
terms or conditions may be waived, but only by a written instrument  executed by
the parties hereto.


     8. Severability; Governing Law


     Should any  provision  of this  Agreement  be held by a court of  competent
jurisdiction  to be  unenforceable  or invalid  for any  reason,  the  remaining
provisions  of this  Agreement  shall not be affected by such  holding and shall
continue in full force in accordance with their terms.


     The  validity,   interpretation,   construction  and  performance  of  this
Agreement shall be governed by the laws of the State of Delaware  without giving
effect to the conflicts of laws principles thereof.


     9. Successors in Interest.


     This  Agreement  shall  inure to the  benefit  of and be  binding  upon any
successor  to the  Company.  All  obligations  imposed  upon the Grantee and all
rights  granted to the Company  under this  Agreement  shall be binding upon the
Grantee's heirs, executors, and administrators.


     10. Resolution of Disputes.


     Any dispute or disagreement which may arise under, or as a result of, or in
any way relate to,  the  interpretation,  construction  or  application  of this
Agreement shall be determined by the Committee. Any determination made hereunder
shall be final,  binding and  conclusive  on the Grantee and the Company for all
purposes.


     11. Withholding of Taxes.


     The Company  shall have the right to deduct from any amount  payable  under
this Agreement, an amount equal to the federal, state and local income taxes and
other amounts as may be required by law to be withheld (the "Withholding Taxes")
with  respect  to any  such  amount.  In  satisfaction  of all  or  part  of the
Withholding Taxes, the Grantee may make a written election (the "Tax Election"),
which may be  accepted or rejected in the  discretion  of the  Company,  to have
withheld a portion of the Shares  issuable  to him or her  pursuant to an Award,
having an aggregate Fair Market Value equal to the Withholding Taxes.

                ASPIRATION ACHIEVEMENT INCENTIVE AWARD AGREEMENT
                FOR EXECUTIVE VICE PRESIDENT AND GROUP PRESIDENT



         THIS AGREEMENT, made as of the 1st day of June, 1999(the "Grant Date"),
between  NATIONAL  SERVICE  INDUSTRIES,  INC., a  Delaware  corporation ("NSI"),
and NSI SERVICES, L.P.(GA), a Subsidiary of NSI (together,  the "Company"),  and
GEORGE H. GILMORE, JR. (the "Grantee").

         WHEREAS,  NSI  has  adopted  the  National  Service  Industries,   Inc.
Long-Term Achievement Incentive Plan (the "Plan") in order to provide additional
incentives to certain  officers and key  employees of NSI and its  Subsidiaries;
and

          WHEREAS,   the  Grantee,  as  an  executive  of  the  above-referenced
Subsidiary, performs services with respect to the CHEMICAL GROUP, NATIONAL LINEN
SERVICE, AND AECO operations of the Company (the "Operations"); and

         WHEREAS,  the Committee  responsible for administration of the Plan has
determined to grant to the Grantee an Aspiration  Achievement Incentive Award as
provided herein.

         NOW, THEREFORE, the parties hereto agree as follows:

         1.       Grant of Aspiration Award.

                  1.1 The Company  hereby  grants to the  Grantee an  Aspiration
Achievement  Incentive  Award (the  "Award"),  which has a value  determined  as
provided in Section 2 below based upon the performance of the Operations  during
the Performance  Cycle from September 1, 1998 to August 31, 2001. As provided in
the Plan,  Grantee's  right to payment of this Award is dependent upon Grantee's
continued  employment in Grantee's  current  position with the Company,  or in a
position with  responsibilities  of  substantially  similar value to the Company
during the remainder of the Performance  Cycle.  Under certain  circumstances as
described below,  Grantee may be entitled to receive payment for some portion of
the Award if Grantee's employment terminates prior to the end of the Performance
Cycle.

                  1.2 The Grantee hereby  acknowledges  receipt of a copy of the
Plan and  agrees  to be bound by all the  terms  and  provisions  thereof.  This
Agreement shall be construed in accordance  with, and subject to, the provisions
of the Plan (the provisions of which are hereby  incorporated by reference) and,
except as otherwise  expressly set forth herein,  the capitalized  terms used in
this Agreement shall have the same definitions as set forth in the Plan.

         2.       Performance Measure and Performance Levels.

                  The Committee has  established  the  performance  measure (the
"Performance Measure"), and award and performance levels set forth in Appendix A
attached  hereto.  The chart in Appendix A specifies  a  Commitment  performance
level,  at  which  the  Commitment  Level  Award  will be  paid,  an  Aspiration
performance level, at or above which an Aspiration Level Award will be paid, and
a threshold  performance  level, at which a minimum incentive award will be paid
and below which no award will be paid. For each level of performance at or above
the  threshold  performance  level  through the  Aspiration  performance  level,
Grantee  will  receive  an award  determined  in  accordance  with the chart and
formulae set forth in Appendix A. The terms used in determining  the Performance
Measure are defined in Appendix B.

         3.       Determination of Aspiration Award.

                  3.1 Determination  Notice.  Subject to Section 3.2, as soon as
practical  following the last day of the Performance  Cycle,  the Committee will
determine, in accordance with Section 7(c) of the Plan, the performance level of
the  Operations  with  respect to the  Performance  Measure for the  Performance
Cycle.  The Committee may in determining the  performance  level with respect to
the  Performance  Measure  adjust  the  Operations'  financial  results  for the
Performance Cycle to exclude the effect of unusual charges or income items which
are distortive of financial results for the Performance Cycle;  provided,  that,
in determining financial results,  items whose exclusion from consideration will
increase the performance  level of the Operations  shall only have their effects
excluded if they  constitute  "extraordinary  items"  under  generally  accepted
accounting principles and all such items shall be excluded.  The Committee shall
also adjust the performance  calculations to exclude the unanticipated effect on
financial results of changes in the Code, or other tax laws, and the regulations
thereunder.  The Committee shall also exclude from  consideration  the effect on
financial  performance of each of the following events or items where the result
of excluding the particular  event or item is to increase the performance  level
of the Operations:  (i) an acquisition or a divestiture  involving more than $10
million  in net  worth or $25  million  in  business  revenues;  (ii) an  equity
restructuring  involving more than $1 million;  (iii) asset  impairment  charges
involving more than $1 million and  restructuring  costs  involving more than $1
million  associated  with facility  closings or reduction in employment  levels;
(iv) changes in accounting  treatment or rules  involving  more than $1 million.
The Committee may decrease the amount of the Award otherwise  payable to Grantee
if,  in the  Committee's  view,  such  adjustment  is  necessary  or  desirable,
regardless of the extent to which the Performance Measure has been achieved. The
Committee may establish  such  guidelines and procedures for reducing the amount
of an Award as it deems appropriate.

                  The  Company  will notify the  Grantee  (or the  executors  or
administrators  of the  Grantee's  estate,  if  applicable)  of the  Committee's
determination  (the  "Determination  Notice").  The  Determination  Notice shall
specify the performance  level of the Operations with respect to the Performance
Measure for the Performance  Cycle and the amount of Award (if any) Grantee will
be entitled to receive.  Unless the Committee  determines  otherwise at the time
the Award is paid and except as  otherwise  provided in the event of a Change in
Control, the amount Grantee is entitled to receive will be paid one-half in cash
and one-half in Shares.  The Shares will be valued at their Fair Market Value as
of the last day of the  Performance  Cycle.  Except  in the case of a Change  in
Control, the Committee may, in its discretion,  attach restrictions,  terms, and
conditions to the Shares issued as part of the Award.

                  3.2 Significant Events Involving the Operations.  If, during a
Performance  Cycle, NSI consummates an acquisition or disposition  involving the
Operations  that (i)  involves  assets  whose value equals or exceeds 20% of the
total value of the  Operations'  assets,  (ii) represents a part of the business
whose revenues equal or exceed 20% of the total of the Operations'  revenues, or
(iii) causes a material  restructuring  of the  Operations,  the following rules
shall apply:

                           (a)      If the  transaction  is  consummated  during
the first year of the Performance Cycle, the Performance Cycle and the Grantee's
outstanding  Award will be terminated with no payout and a new Performance Cycle
containing a new Award will be started.

                           (b)      If  the  transaction  is  consummated  after
the first year of the Performance  Cycle, the Performance Cycle will end and the
outstanding  Award  will  be  determined  and  paid  at the  Operations'  actual
performance level to such date, taking into account the adjustments provided for
in Section 3.1 above and using prorated  performance  levels of the  Performance
Measure to reflect the portion of the  Performance  Cycle that had elapsed as of
the date of consummation of the acquisition or disposition. Payment of the Award
will be made as soon as  practical  after it is  determined.  A new  Performance
Cycle will be started to cover the period  remaining in the initial  Performance
Cycle  or,  if  that  result  is not  practical,  the  Committee  will  make  an
appropriate  adjustment  to reflect  the  premature  termination  of the initial
Performance Cycle.

                           If, during  a  Performance  Cycle, NSI consummates an
acquisition or disposition that is not covered by the special provisions of this
Section 3.2, the financial  effects of such acquisition or disposition  shall be
handled as provided in Section 3.1.

                           Any actions  under this Section 3.2 shall be taken in
accordance with the requirements of Code Section
162(m) and the regulations thereunder.

         4.       Termination of Employment.

                  4.1 In General.  Except as provided in Sections  4.2, 4.3, and
4.4  below,  in the event  that the  Grantee's  employment  terminates  during a
Performance Cycle, all unearned Aspiration Awards shall be immediately forfeited
by the Grantee.

                  4.2  Termination  of Employment Due to Death,  Disability,  or
Retirement.  In the event the  employment of the Grantee is terminated by reason
of death or Disability during a Performance Cycle, the Grantee shall be entitled
to a prorated  payout with respect to the unearned  Award.  The prorated  payout
shall be  determined  by the  Committee  based  upon the length of time that the
Grantee was actively  employed during the Performance Cycle relative to the full
length of the Performance  Cycle;  provided,  that payment shall only be made to
the extent at the end of the Performance  Cycle the Award would have been earned
based upon the performance level achieved for the Performance Cycle (taking into
account  the  adjustment  provisions  and other  rules in Section 3 above);  and
provided,  further,  that the  performance  level used to determine the prorated
award cannot exceed 200% of the Commitment performance level.

                           In the event of Grantee's Retirement (on or after age
65),  the full Award shall  continue to be eligible for payout at the end of the
Performance Cycle, just as if Grantee had remained employed for the remainder of
the Performance Cycle (including if the Grantee dies after Retirement but before
the end of the  Performance  Cycle).  At the end of the Performance  Cycle,  the
Committee shall make its determination in the same manner as provided in Section
3.

                           Payment of earned  Awards  to Grantee in the event of
termination due to death,  Disability,  or Retirement  shall be made at the same
time payments  would be made to Grantee if Grantee did not terminate  employment
during the Performance Cycle.

                  4.3  Change  In  Control.  Notwithstanding  anything  in  this
Agreement to the contrary,  if a Change in Control occurs during the Performance
Cycle,  then the Grantee's Award shall be determined for the  Performance  Cycle
then in progress as though the Performance Cycle had ended as of the date of the
Change in Control and the outstanding Award will be paid at the Commitment Level
Award or the actual  performance  level to such date (using,  for such  purpose,
prorated performance levels of the Performance Measure to reflect the portion of
the Performance Cycle that has elapsed as of the date of the Change in Control),
whichever provides the greater payment.  The Award determined in accordance with
the  preceding  sentence  shall be fully vested and payable  immediately  to the
Grantee.  The  Committee  shall  determine  the  amount of the Award  under this
Section 4.3, subject to the terms of this section, and no downward adjustment of
the Award which would result in reduction of the Award by more than 50% shall be
permitted.  The Award will be paid in full in cash, unless the Grantee elects to
receive one-half of the Award in Shares.  For purposes of determining the number
of Shares to be paid to the  Grantee  under this  Section  4.3,  the Fair Market
Value of a Share shall be  determined  by taking the average  closing  price per
share for the last twenty (20)  trading  days prior to the  commencement  of the
offer, transaction, or other event which resulted in a Change in Control.

                  4.4   Termination   Without  Cause.  In  the  event  Grantee's
employment  is  terminated  by the Company  without Cause more than one (1) year
after  the  commencement  of the  Performance  Cycle and prior to the end of the
Performance  Cycle,  the Grantee  shall be entitled to a prorated  payout of the
Award  based  upon the length of time that the  Grantee  was  actively  employed
during the  Performance  Cycle  relative to the full  length of the  Performance
Cycle; provided, that payment shall be made only to the extent at the end of the
Performance  Cycle the Award would have been earned  based upon the  performance
level achieved during the Performance  Cycle (taking into account the adjustment
provisions and other rules in Section 3 above); and provided,  further, that the
performance level used to determine the prorated award cannot exceed 200% of the
Commitment  performance level. Payment shall be made to Grantee at the same time
as if Grantee had not terminated employment during the Performance Cycle.

         5.       No Right to Continued Employment.

                  Nothing in this  Agreement or the Plan shall be interpreted to
confer upon the Grantee any rights with respect to  continuance of employment by
the Company,  nor shall this Agreement or the Plan interfere in any way with the
right of the Company to terminate the Grantee's employment at any time.

         6.       Nonassignment.

                  The  Grantee  shall  not have the right to  assign,  alienate,
pledge, transfer, or encumber any amounts due Grantee hereunder, and any attempt
to assign, alienate,  pledge, transfer, or encumber Grantee's rights or benefits
shall be null and void and not recognized by the Plan or the Company.

         7.       Modification of Agreement.

                  This  Agreement  may  be  modified,   amended,  suspended,  or
terminated,  and any terms or  conditions  may be waived,  but only by a written
instrument executed by the parties hereto.

         8.       Severability; Governing Law.

                  Should any  provision of this  Agreement be held by a court of
competent  jurisdiction  to be  unenforceable  or invalid  for any  reason,  the
remaining provisions of this Agreement shall not be affected by such holding and
shall continue in full force in accordance with their terms.

                  The validity, interpretation, construction, and performance of
this  Agreement  shall be governed by the laws of the State of Delaware  without
giving effect to the conflicts of laws principles thereof.

         9.       Successors in Interest.

                  This  Agreement  shall  inure to the benefit of and be binding
upon any successor to the Company.  All obligations imposed upon the Grantee and
all rights granted to the Company under this Agreement shall be binding upon the
Grantee's heirs, executors, and administrators.

         10.      Resolution of Disputes.

                  Any dispute or  disagreement  which may arise  under,  or as a
result  of,  or in any way  relate  to,  the  interpretation,  construction,  or
application  of  this  Agreement  shall  be  determined  by the  Committee.  Any

                                  AMENDMENT OF
                        ASPIRATION ACHIEVEMENT INCENTIVE

                                  ELECTION FORM



     WHEREAS, the undersigned  Participant was granted an Aspiration Award under
the NSI Long-Term  Achievement  Incentive Plan (the "Plan") for the  Performance
Cycle ending August 31, 1999; and

     WHEREAS,  under the Plan, the amount (if any) of the  Aspiration  Award the
Participant will receive for such Performance Cycle is currently uncertain; and

     WHEREAS, the Plan has been amended to permit the Participant to receive all
or a portion of the Aspiration Award in a different form;

     NOW,  THEREFORE,  the  Participant  hereby elects to receive any Aspiration
Award earned for the  Performance  Cycle ending  August 31, 1999,  in the manner
provided below and agrees to amend the Aspiration  Achievement  Incentive  Award
Agreement in accordance with such election:

     I. AMENDMENT TO SURRENDER / EXCHANGE  AWARD (OR PORTION  THEREOF) FOR STOCK
OPTIONS.  By checking  "YES" below,  you are  electing to amend your  Aspiration
Achievement  Incentive Award  Agreement for the Performance  Cycle ending August
31, 1999 to provide that your Award (or a portion  thereof) will be exchanged as
indicated,  to the fullest extent possible,  for the grant of Options to acquire
NSI stock under the terms set forth below.
<PAGE>
                                                                         Page 55
                                                             EXHIBIT 10(iii)A(8)


     Originally,  one-half of the Aspiration Award,  determined as of August 31,
1999,  was to have been paid in cash and one-half in NSI stock.  If you elect to
amend your Agreement,  the value of the component of your Aspiration Award which
would have  originally  been paid in NSI stock will be  adjusted  to reflect any
change  in  NSI's  stock  price  during  the  period  August  31,  1999  to  the
Determination  Date (meaning  that date in October,  1999 on which the Executive
Resource and  Compensation  Committee of the Board of Directors  determines  the
amount of the Award  earned and  payable).  The total  value of the Award at the
Determination Date will therefore be equal to the total of (a) the amount of the
Award as of August 31, 1999 and (b) the amount (either gain or loss)  calculated
by multiplying  (i) the number of shares you would have  originally  received by
(ii) the amount resulting from subtracting the Fair Market Value of NSI stock on
August 31 from the Fair Market Value at the Determination Date.

     The amount of your  Aspiration  Award  exchanged  for  Options  will not be
currently taxable (i.e., it will be treated similarly to a bonus deferral).  The
Options will be nonqualified  options under the Plan. Please see the description
of the tax treatment for nonqualified options attached hereto as Exhibit "1". Of
course, you should consult your tax advisor.

_____ YES, I elect to amend my  Agreement  to provide for the exchange of all of
my Award (or a portion thereof),  to the fullest extent possible,  for the grant
of  Options  to  acquire  NSI stock  under the  terms  set forth  below,  in the
following manner:

      [ ]  In exchange for $__________ of my Award (minimum $1,000).

      [ ]  In exchange for _________% of my Award (minimum $1,000).

      [ ]  In exchange for the grant of _________ Options (minimum 100 options).

                                                             EXHIBIT 10(iii)A(8)


The portion of the Award elected above (whether measured in dollars, percentage,
or  Options)  will be  surrendered  from the  total  value  of the  Award at the
Determination  Date. The  calculation of Options granted in the exchange will be
rounded down to the next whole  amount.  Any  unexchanged  portion of your Award
will be payable half in NSI stock and half in cash.

_____ NO, I elect to continue to receive the entire  Award  payment  half in NSI
stock and half in cash.



Terms of Stock Options:

          (a) Each  Option  will be valued for  purposes  of the  surrender  and
     exchange at a percentage,  as provided  below,  of the Fair Market Value of
     NSI stock (closing price on NYSE) on the Determination Date:

               (1) At  24.35%,  if the Fair  Market  Value of NSI stock is below
          $40.00 on the Determination Date;

               (2) At 20.00%, if the Fair Market Value of NSI stock is $40.00 or
          greater on the Determination Date.

     This  value  is  less  than  the  Black-Scholes  formula  to  be  used  for
     determining an annual option grant award.

          (b) The exchange will be limited by the size of your Award payment and
     may be further reduced,  on a pro rata basis, for Options elected in excess
     of the number of Options  granted to you in  September  1998 (or a fraction
     thereof  determined by the  Committee on the  Determination  Date),  if the
     total  number of Options  elected by all  participants  exceeds the pool of
     Options  available for exchange.  It is the intention of the Committee that
     300,000 Options will be available for exchange. The final number of Options
     available will be established by the Committee at the  Determination  Date,
     and your election  will be adjusted in accordance  with the final number of
     Options available.

          (c) The Options  will be  nonqualified  stock  options,  will be fully
     vested at the time of  receipt,  and will have a  ten-year  term  except as
     follows:

               (1)  in  the  case  of  termination  due  to  death,  Disability,
          retirement  at or after  age 65,  or  involuntary  termination  by the
          Company  (other than for cause),  the Options will remain  exercisable
          until seven years after the date of grant,  or one year after the date
          of termination, whichever is later;

               (2) in the case of voluntary termination, the Options will remain
          exercisable  until 90 days after the date of  termination;  and

               (3) in the  case of  involuntary  termination  for  "cause",  the
          Options will expire on the date of termination.

     The Options  will  generally  have such other terms and  conditions  as the
     nonqualified Options granted by the Company in September 1998.

                                  TAX TREATMENT




         Nonqualified Stock Options ("NSOs").  On exercise of an NSO, the amount
by which the  market  price of the Shares on the date of  exercise  of the Stock
Option  exceeds the purchase  price for the Shares will  generally be taxable to
the  Participant  as ordinary  income and will  generally be deductible  for tax
purposes by NSI. Selling or transferring the Shares acquired upon exercise of an
NSO will  generally  result in a capital gain or loss for the  Participant,  but
will have no tax  consequences for NSI. The gain or loss will be measured by the
difference  between the amount realized on disposition of the Shares and the tax
basis of the Shares. The tax basis for the Shares will generally be equal to the
amount taken into ordinary  income upon  exercise of the Stock Option,  plus the
amount of cash paid by the Participant  upon exercise of the Stock Option (which
will in the  aggregate  generally  be equal to the market price of the Shares at
the time the Stock Option was exercised).

         Aspiration  Awards.  The grant of an Aspiration  Award  pursuant to the
Plan will not result in income for the  Participant  or in a tax  deduction  for
NSI.  Upon the  settlement  of such an Award,  the  Participant  will  recognize
ordinary  income  equal to the fair market  value of any Shares  and/or any cash
