             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, 1999 has been  derived  from  audited  statements.  These  statements
reflect all 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  February  29,  2000,  the  consolidated  results  of
operations for the three and six months ended February 29, 2000 and February 28,
1999, and the consolidated cash flows for the six months ended February 29, 2000
and  February 28, 1999.  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, 1999.

The results of operations  for the three and six months ended  February 29, 2000
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.    ACCOUNTING STANDARDS YET TO BE ADOPTED

Statement of Financial  Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities," was issued in June of 1998 and is effective
for all fiscal  quarters of fiscal  years  beginning  after June 15,  2000.  The
company  is in  the  process  of  evaluating  the  impact  of  adoption  on  the
Consolidated Balance Sheets and Consolidated Statements of Income.

5.    EARNINGS PER SHARE

The company  accounts  for  earnings  per share  using  Statement  of  Financial
Accounting  Standards  ("SFAS")  No.  128,  "Earnings  per  Share."  Under  this
statement,  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 February 29 and February 28:

6.    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 six months ended
February  29,  2000  and  February  28,  1999  includes  only  foreign  currency
translation adjustments. The calculation of comprehensive income is as follows:

7.    ENVIRONMENTAL MATTERS

The company's operations,  as well as similar operations of other companies, are
subject  to  comprehensive  laws and  regulations  relating  to the  generation,
storage,  handling,  transportation,  and disposal of hazardous  substances  and
solid and hazardous wastes and to the remediation of contaminated sites. Permits
and environmental  controls are required for certain of the company's operations
to limit air and water pollution, and these permits are subject to modification,
renewal, and revocation by issuing authorities.  The company believes that it is
in substantial compliance with all material environmental laws, regulations, and
permits.  On an ongoing basis,  the company  incurs capital and operating  costs
relating to environmental  compliance.  Environmental  laws and regulations have
generally  become stricter in recent years, and the cost of responding to future
changes may be substantial.

The company's environmental reserves, which are included in current liabilities,
totaled  $10,788  and  $11,000  at  February  29,  2000  and  August  31,  1999,
respectively. The actual cost of environmental issues may be substantially lower
or higher than that reserved due to the  difficulty  in  estimating  such costs,
potential changes in the status of government regulations,  and the inability to
determine  the  extent  to which  contributions  will be  available  from  other
parties.  The company does not believe that any amount of such costs below or in
excess of that accrued is reasonably estimable.

Certain  environmental  laws,  such as Superfund,  can impose  liability for the
entire cost of site  remediation  upon each of the  current or former  owners or
operators  of a site or  parties  who sent  waste to a site where a release of a
hazardous  substance has occurred  regardless of fault or the  lawfulness of the
original disposal activity.  Generally,  where there are a number of potentially
responsible  parties  ("PRPs") that are financially  viable,  liability has been
apportioned  based on the type and amount of waste  disposed of by each party at
such  disposal  site and the number of  financially  viable  PRPs,  although  no
assurance as to the method of apportioning  the liability can be given as to any
particular site.



<PAGE>


                                                                          Page 9

The company is currently a party to, or otherwise involved in, legal proceedings
in connection with state and federal  Superfund  sites, two of which are located
on  property  owned by the  company.  Except  for the  Crymes  Landfill  and M&J
Solvents matters in Georgia, the company believes its liability is de minimis at
each of the sites which it does not own where it has been named as a PRP. At the
Crymes  Landfill  and M&J  Solvents  sites in  Georgia,  since the  matters  are
currently  in the  investigative  phase,  the company  does not know whether its
liability is de minimis but  believes  that its exposure at each of the sites is
not  likely to result in a material  adverse  effect on the  company  due to its
limited  involvement  at the sites and the number of viable  PRPs.  For property
which the company owns on Seaboard Industrial Boulevard in Atlanta, Georgia, the
company has  conducted an  investigation  on its and  adjoining  properties  and
submitted  a  Compliance   Status  Report   ("CSR")  to  the  State  of  Georgia
Environmental Protection Division ("EPD") pursuant to the Georgia Hazardous Site
Response Act. The company is currently  responding to EPD's  comments  regarding
the CSR.  Until 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  approximately  $430 of costs already  incurred by the State of
Florida in connection with such contamination.  The company believes that it has
a strong defense due to likely off-site sources of the contamination and because
contamination  from the  property,  if any,  was due to prior owners and not the
company's  operations.  At this time,  it is too early to quantify the company's
potential exposure or the likelihood of an adverse result.

The company is currently evaluating emissions of volatile organic compounds from
its manufacturing  operations in the Atlanta,  Georgia area to determine whether
it will need to install  pollution control equipment or modify its operations to
comply  with  federal  and state air  pollution  regulations.  Until the current
evaluations are completed, the company is not able to quantify the possible cost
of compliance.  However, based upon currently available information, the company
does not expect  that any  material  expenditures  will be  required  to achieve
compliance.

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   environmental
liabilities  arising  from events  occurring  prior to the  closing,  subject to
certain  exceptions.  The  company  has  received  notice  from the buyer of the
textile rental plants of the alleged presence of perchloroethylene contamination
on one of the properties involved in the sale. The company has since asserted an
indemnification claim against the company from which it bought the property. The
prior owner is currently conducting an investigation of the contamination at its
expense,  subject to a reservation  of rights.  At this time, it is too early to
quantify the company's  potential  exposure in this matter, the likelihood of an
adverse result,  or the  possibility  that the company may be fully or partially
indemnified.

The State of New York has filed a lawsuit against the company  alleging that the
company is responsible as a successor to Serv-All  Uniform Rental Corp. for past
and future response costs in connection  with the release or threatened  release
of hazardous substances at and from the Blydenburgh Landfill in Islip, New York.
The company believes that it is not a successor to Serv-All Uniform Rental Corp.
and therefore has no liability with respect to the Blydenburgh Landfill,  and it
has responded to the lawsuit accordingly. At this stage of the litigation, it is
too early to quantify the company's  potential  exposure or the likelihood of an
adverse result.

8.    INCREASE IN SHARES AUTHORIZED UNDER LONG-TERM ACHIEVEMENT INCENTIVE PLAN

On January 5, 2000,  the  stockholders  approved an  amendment  to the  National
Service Industries, Inc. Long-Term Achievement Incentive Plan for the benefit of
officers  and  other  key  employees  of  the  company.  In  addition  to  other
modifications,  the  amendment  increases  the number of shares  authorized  for
issuance under the plan from 1,750,000 to 5,750,000.

                      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 solid financial condition at February
29, 2000.  Net working  capital was $275.2  million,  up from $256.5  million at
August 31, 1999, and the current ratio remained constant at 1.6. At February 29,
2000, the company's percentage of debt to total capitalization increased to 49.0
percent from 47.2 percent at August 31, 1999.

Results of Operations

National Service Industries generated revenue of $605.4 million and $1.2 billion
in the three and six months ended February 29, 2000, respectively, compared with
revenue of $510.4  million  and $1.0  billion in the three and six months  ended
February 28, 1999,  respectively.  The  increase was  primarily  due to acquired
revenue in the lighting equipment and envelope segments.  The lighting equipment
segment purchased Holophane  Corporation  ("Holophane") in July 1999 and certain
assets of Peerless  Corporation  ("Peerless")  in April 1999.  In addition,  the
envelope  segment  purchased  substantially  all of Gilmore Envelope in February
1999. These acquisitions  generated combined revenue of $70.3 million and $155.6
million for the three and six months ended February 29, 2000, respectively, that
was  not  included  in  prior-year  results.  Excluding  acquisitions,   revenue
increased in each of the company's core businesses.

Net  income  totaled  $20.3  million  and $44.7  million,  or $.50 and $1.10 per
diluted  share,   for  the  three  and  six  months  ended  February  29,  2000,
respectively, compared to net income of $24.8 million and $50.5 million, or $.60
and $1.22 per diluted  share,  for the three and six months  ended  February 28,
1999.  Income from  acquisitions  not  included in prior year results and income
from core business growth in the lighting  equipment and chemical  segments were
more than offset by increased  interest  expense on borrowings and  amortization
expense related to recent acquisitions. Additionally, operating profit decreased
in the textile rental segment as the second quarter of fiscal 1999 included $3.5
million in unusual gains  compared to $.7 million  during the second  quarter of
fiscal 2000.  Current year to date net income also included a charge for closing
a manufacturing facility in the lighting equipment segment.

The lighting  equipment  segment  reported  revenue of $354.1 million and $721.7
million for the three and six months  ended  February  29,  2000,  respectively,
representing  an increase of 29.9 percent and 29.6  percent over the  respective
periods  of  the  prior  year.  These  increases  resulted  primarily  from  the
acquisitions of Holophane and Peerless. Additionally,  continued strength in the
non-residential  construction market had a positive impact on lighting equipment
revenue  resulting in growth in the segment's  core business.  Operating  profit
increased  21.7  percent  and 20.6  percent  for the three and six months  ended
February 29, 2000,  respectively,  driven by  contributions  from  Holophane and
Peerless, growth in the segment's core business, and containment of fixed costs,
offset  somewhat by a $1.0 million  pretax  charge  during the first  quarter of
fiscal 2000 for closing a manufacturing facility in California.

Chemical segment revenue  increased 2.5 percent to $119.6 million for the second
quarter  and 2.6 percent to $239.5  million for the six months due to  continued
growth in the retail  channel  and higher  revenue  from the  institutional  and
industrial channels,  resulting primarily from an increase in the segment's core
business.  Operating  profit of $11.5 million and $20.1 million during the three
and six months  ended  February  29,  2000,  respectively,  was higher than last
year's  results  primarily  due to a  reduction  in general  and  administrative
expenses, fluctuations in selling expenses, and an increase in revenue.

Textile  rental  segment  revenue,  representing  all of the  company's  service
revenues, increased 4.9 percent to $77.4 million for the quarter and 3.9 percent
to $155.1  million for the six months.  The current  year  revenue  increase was
primarily  related to acquired revenue and price increases in the segment's base
business,  offset somewhat by the negative impact of ice storms in the Southeast
during the second quarter.  Operating profit decreased to $6.3 million from last
year's $9.2  million  for the second  quarter  and to $11.4  million  from $15.9
million for the first half of the year  primarily as a result of $3.5 million of
unusual items being included in the prior year compared to a $.7 million gain on
the sale of property in the current quarter.  Operating profit for the three and
six months  ended  February  28, 1999  included  $5.7  million of unusual  gains
related to the 1997 uniform plants  divestiture  and  restructuring  activities,
offset  by  a  $2.2  million   write-off  for  merchandise   inventory  used  by
unprofitable accounts.  Excluding unusual items in both years, operating margins
for the quarter remained flat. However,  year to date margins declined as higher
fuel costs,  the impact of adverse  weather,  and contract  wage  increases  for
production employees more than offset the increase in revenue.

Envelope  segment  revenue  increased  14.8  percent to $54.3  million  and 21.3
percent to $109.1  million for the three and six months ended February 29, 2000,
respectively,  while operating profit decreased 21.3 percent to $2.5 million and
17.0  percent to $5.5  million for the three and six months  ended  February 29,
2000, respectively.

Revenue  increased due to additional  sales resulting from the Gilmore  Envelope
acquisition and continued volume growth in the base business, offset somewhat by
the prior year  divestiture  of  Techno-Aide/Stumb  Metal Products in June 1999.
Operating margin percentages decreased during the three and six month periods as
a result of lower  average  margins from prior year  acquisitions,  higher paper
prices which were passed on to customers,  pre-production  costs associated with
newly acquired manufacturing  equipment,  and depreciation from a new enterprise
resource planning system.

Corporate expenses increased to $5.6 million during the second quarter primarily
due to costs  related to strategic  initiatives.  For the six months,  corporate
expenses  decreased  to $7.9 million as costs  related to strategic  initiatives
were  offset by lower  incentive  compensation  expense.  Net  interest  expense
increased  $8.0 million to $10.5  million and $15.6 million to $20.5 million for
the three and six months ended February 29, 2000,  respectively,  as a result of
increased borrowings to finance recent acquisitions. Additionally, the provision
for income taxes was 38.8 percent of pretax income for the quarter compared with
37.2 percent in the prior-year  period primarily due to goodwill recorded in the
Holophane acquisition, which is not deductible for tax purposes.


Liquidity and Capital Resources

Operating Activities

Operations  provided cash of $20.9 million  during the first half of fiscal 2000
compared with $52.4 million during the first six months of fiscal 1999. The 2000
cash flow was lower  primarily  because  of a decrease  in  current  liabilities
related to  incentive  compensation  plan  payments,  an  increase in income tax
payments,  and a  decrease  in  accounts  payable.  Additionally,  increases  in
inventory, offset somewhat by a decrease in accounts receivable primarily in the
lighting equipment  segment,  contributed to the decrease in operating cash flow
compared to the prior year.

Investing Activities

Investing  activities  used  cash of  $65.6  million  for the six  months  ended
February  29, 2000  compared  with cash used of $70.0  million in the six months
ended February 28, 1999. The change in investing cash flows relates primarily to
a decrease  in  acquisition  spending  offset by an  increase  in  purchases  of
property, plant, and equipment. Acquisition spending during the first six months
of fiscal 2000 was $21.5 million and related primarily to Holophane. The company
purchased  Holophane in July 1999 for  approximately  $470.8 million,  including
approximately  $20 million for the payoff of  Holophane's  existing debt. Of the
total  purchase  price,  $454.6  million was paid  during  fiscal 1999 and $14.5
million  was paid  during the first six months of the  current  year,  which was
primarily  for the cash-out of remaining  Holophane  shares.  Other  acquisition
spending during the first half of fiscal 2000 related to several minor purchases
in the textile rental segment.  Prior year acquisition spending of $39.2 million
was primarily due to the lighting equipment segment's purchase of certain assets
of GTY  Industries  (d/b/a  "Hydrel"),  a  manufacturer  of  architectural-grade
lighting fixtures for landscape,  in-grade, and underwater applications, and the
envelope  segment's  purchase  of  substantially  all of  Gilmore  Envelope,  an
envelope manufacturer headquartered in Los Angeles, California.

Capital  expenditures were $47.4 million in the first six months of fiscal 2000,
compared  with $32.0  million in the first six  months of fiscal  1999.  Capital
spending during the first half of fiscal 2000 was primarily  attributable to the
lighting  equipment,   envelope,  and  textile  rental  segments.  The  lighting
equipment segment invested in land, buildings, and equipment for a new plant and
in manufacturing upgrades and improvements. Capital expenditures in the envelope
segment  related  primarily  to  new  folding  capacity,  manufacturing  process
improvements, and information systems. The textile rental segment's expenditures
related  to  replacing   old  equipment   and  delivery   truck   purchases  and
refurbishments.  The lighting  equipment  segment's capital  expenditures in the
prior-year  first half related to the purchase of land and  buildings  for a new
plant,  manufacturing  improvements  and upgrades for  capacity  expansion,  and
implementation of new technology.  Textile rental segment  expenditures 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.  Management believes current cash balances,
anticipated  cash flows from  operations,  available  funds from the  commercial
paper program or the committed credit facilities, and the complementary lines of
credit are  sufficient to meet the company's  planned level of capital  spending
and general operating cash requirements for the next twelve months.

Financing Activities

Cash provided by financing  activities  decreased $16.9 million to $43.9 million
in the first half of fiscal  2000  primarily  as a result of a decrease  in cash
provided by net  borrowings,  offset by the  suspension of the  company's  share
repurchase program in the third quarter of fiscal 1999. Although the company has
a standing annual authorization to repurchase 2.0 million shares plus the number
of new shares  issued in any one year,  the  company  does not plan to  purchase
additional  shares  until its debt to  capitalization  is within  the  company's
stated  objective  of 30 to 40 percent.  For the six months  ended  February 29,
2000, net borrowings,  primarily under the company's  commercial  paper program,
provided cash of $68.3 million  compared with cash provided by net borrowings of
$110.3 million during the same period of the prior year. Current year borrowings
were  used  for  general   corporate   purposes,   including   working   capital
requirements,  capital expenditures,  and acquisitions. At February 29, 2000 and
August 31, 1999,

approximately  $250 million in commercial  paper was  classified as long-term as
the company has the ability to  refinance  the  commercial  paper on a long-term
basis.  Funds borrowed  during the first half of fiscal 1999 were used primarily
to finance  acquisitions,  share  repurchases,  and  internal  growth.  Dividend
payments  totaled  $26.4  million,  or 65 cents per share,  compared  with $26.0
million,  or 63 cents per share, for the prior-year  period. On January 5, 2000,
the regular  quarterly  dividend  rate was increased 3.1 percent to 33 cents per
share, or an annual calendar year rate of $1.32 per share.

Environmental Matters

See Note 7: Environmental Matters for a discussion of the company's
environmental issues.

Impact of the Year 2000 Issue

The company did not  experience,  nor does it expect to experience,  significant
disruptions to its mission  critical  systems related to the Year 2000 Issue. As
of April 14,  2000,  all of the  company's  mission  critical  systems have been
tested and are fully  operational.  However,  no assurance can be given that the
cost of remediating  any problems  associated  with the Year 2000 Issue will not
materially affect the company's business.

Quantitative and Qualitative Disclosures about Market Risk

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

Interest Rates- Interest rate  fluctuations  expose the company's  variable-rate
debt to changes in interest expense and cash flows. The company's  variable-rate
debt,  primarily  commercial  paper,  amounted to $455.4 million at February 29,
2000.  Based on  outstanding  borrowings  at quarter  end, a 10 percent  adverse
change in effective  market  interest rates at February 29, 2000 would result in
additional  annual after-tax  interest  expense of  approximately  $1.7 million.
Although a fluctuation  in interest rates would not affect  interest  expense or
cash flows  related to the $160 million  publicly  traded  notes,  the company's
primary  fixed-rate  debt, a 10 percent  increase in effective  market  interest
rates at  February  29,  2000 would  decrease  the fair value of these  notes to
approximately $134.4 million.

Foreign  Exchange  Rates-The  majority of the company's  revenue,  expense,  and
capital  purchases are  transacted  in U.S.  dollars.  International  operations
during the first half of fiscal 2000,  primarily in the lighting  equipment  and
chemical  segments,  represented  approximately 9.5 percent of sales and service
revenues,   4.5  percent  of  operating  profit  (loss),   and  8.4  percent  of
identifiable  assets.  The company does not believe a 10 percent  fluctuation in
average foreign  currency rates would have a material effect on its consolidated
financial statements or results of operations.

Cautionary Statement Regarding Forward-Looking Information

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

                             STOCK OPTION AGREEMENT
                            FOR NONEMPLOYEE DIRECTORS




         THIS  AGREEMENT,  made as of the 5th day of  January,  2000 (the "Grant
Date"),  between National Service Industries,  Inc., a Delaware corporation (the
"Company"), and Name (the "Optionee").

         WHEREAS, the Company has adopted the National Service Industries,  Inc.
1992  Nonemployee  Directors' Stock Option Plan (the "Plan") in order to provide
additional  incentive to nonemployee  directors to exert maximum efforts for the
success of the Company; and

         WHEREAS, pursuant to the terms of the Plan, the Optionee is entitled to
the option grant 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 1,500 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 422A 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 $27.6875 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,  the shares covered by the option after the expiration of one
(1) year from the Grant Date.

         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,  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  12 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 Service.

                  6.1  Termination  for Cause.  If the  Optionee's  service as a
Director  terminates for Cause, the Option shall  immediately  terminate in full
and no rights hereunder may be exercised.

                  6.2 Other Termination of Service. If the Optionee's service as
a Director is terminated  for any reason other than for Cause,  the Option shall

continue to be exercisable in whole or in part (to the extent exercisable on the
date of such  termination)  at any time within three (3) years after the date of
such termination,  but in no event after the expiration of the Exercise Term. In
the event of the  Optionee's  death,  the Option  shall be  exercisable,  to the
extent provided in the Plan and this Agreement, by the legatee or legatees under
his will, or by his personal  representatives or distributees and such person or
persons shall be substituted for the Optionee each time the Optionee is referred
to herein.

         7.       Effect of Change in Control.

                  Notwithstanding  anything  contained in this  Agreement to the
contrary,  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

equal to the excess, if any, of (A) the greater of (x) the Fair Market value, on
the date  preceding  the date of the  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 the  portion  of the  Option
surrendered,  over (B) the  aggregate  purchase  price for such Shares under the

service as a director at any time.

         4.       Exercisability of Option.

                  The  Option  is,  immediately  upon  grant,  fully  vested and

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

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

death,  Disability,  Retirement  (termination on or after age 65),  termination
by the Company other than for cause,  termination after attaining age 55, or
voluntary termination, the following shall apply:

                  (a)      Termination  Due To Death.  In the event the Optionee
                           dies while actively employed, the Option shall remain
                           exercisable  until  seven (7) years after the date of
                           grant or one (1) year after the date of  termination,
                           whichever  is later  (but in any event not beyond 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  Option 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.

                  (b)      Termination   by   Disability.   In  the   event  the
                           employment of the Optionee is terminated by reason of
                           Disability, the Option shall remain exercisable until
                           seven  (7)  years  after the date of grant or one (1)
                           year  after  the date the  Committee  determines  the
                           Optionee  terminated  for  Disability,  whichever  is
                           later  (but in any  event  not  beyond  the  Exercise
                           Term).  In the event of the  Optionee's  death  after
                           such  termination,  the Option  shall  continue to be
                           exercisable in accordance with this subsection (b) as
                           if the  Optionee  had lived and the Options  shall be
                           exercisable by the persons described in (a) above.

                  (c)      Termination  by Retirement or by the Company  Without
                           Cause. In the event the employment of the Optionee is
                           terminated by reason of  Retirement  (at or after age
                           65) or by the Company  for any reason  other than for
                           cause,  the Option  shall  remain  exercisable  until
                           seven (7)  years  after the date of grant or five (5)
                           years  after the date of  termination,  whichever  is
                           later  (but in any  event  not  beyond  the  Exercise
                           Term).  In the event of the  Optionee's  death  after
                           such  Retirement  or  termination,  the Option  shall
                           continue to 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. In the event 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 Option
                           shall remain  exercisable  until five (5) years after
                           the date of grant (but not beyond the Exercise Term).
                           In the  event  of the  Optionee's  death  after  such
                           termination,   the  Option   shall   continue  to  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.

                  (e)      Voluntary   Termination.   In  the   event   Optionee
                           voluntarily terminates employment,  the Options shall
                           remain  exercisable  until ninety (90) days after the
                           date of  termination  (but not  beyond  the  Exercise
                           Term).

         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, the Optionee shall 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,  the  Option  shall  continue  to be
exercisable  at any time until  seven (7) years after the date of grant or three
(3) years after the date of such termination of employment,  whichever is later,
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
entitled to receive  Shares upon exercise of the Option,  the Optionee shall pay
the  Withholding  Taxes 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.

         13.      Employee Bound by the Plan.

                  The Optionee hereby acknowledges receipt of a copy of the Plan
and agrees to be bound by all the terms and provisions thereof.

                        INCENTIVE STOCK OPTION AGREEMENT
              FOR EXECUTIVE OFFICERS AND OPERATING UNIT PRESIDENTS


         THIS  AGREEMENT,  made as of the 5th day of  January,  2000 (the "Grant
Date"),  between National Service Industries,  Inc., a Delaware corporation (the
"Company"), and Name (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 Amount
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 $27.6875 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,  Para.  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.

                                                             Exhibit 10(iii)A(4)

         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 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.  During the lifetime of the Optionee,  the
Option shall be exercisable only by the Optionee.

         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 and Notice of Disposition.

                  12.1 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
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.

         13.      Employee Bound by the Plan.

                  The Optionee hereby acknowledges receipt of a copy of the Plan
and agrees to be bound by all the terms and provisions thereof.

              FOR EXECUTIVE OFFICERS AND OPERATING UNIT PRESIDENTS



         THIS  AGREEMENT,  made as of the 5th day of  January,  2000 (the "Grant

         WHEREAS, the Company has adopted the National Service Industries,  Inc.
Long-Term Achievement Incentive Plan (the "Plan") in order to provide additional

         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 Amount
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

same definitions as set forth in the Plan.

         2.       Purchase Price.

                  The price at which the Optionee  shall be entitled to purchase

         3.       Duration of Option.

                  The  Option  shall be  exercisable  to the  extent  and in the

         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, Para, 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 escribed 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
entitled to receive  Shares upon exercise of the Option,  the Optionee shall pay
the  Withholding  Taxes 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.

         13.      Employee Bound by the Plan.

                  The Optionee hereby acknowledges receipt of a copy of the Plan
and agrees to be bound by all the terms and provisions thereof.

         14.      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.

         15.      Severability.

                  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.

         16.      Governing Law.

                  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.

         17.      Successors in Interest.

                  This  Agreement  shall  inure to the benefit of and be binding
upon each successor  corporation.  This Agreement  shall inure to the benefit of
the Optionee's legal representatives.  All obligations imposed upon the Optionee
and all rights  granted to the  Company  under  this  Agreement  shall be final,
binding,  and  conclusive  upon  the  Optionee's  heirs,  executors,   Permitted
Transferees, administrators, and successors.

         18.      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
Optionee and the Company for all purposes.
