     THIS  AGREEMENT,  made as of the 17th day of  September,  1996 (the  "Grant

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

meaning of Section 422 of the Code.

     3. Duration of Option.

          The  Option  shall be  exercisable  to the  extent  and in the  manner

"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 Program, the Option
shall  entitle the  Optionee to  purchase,  in whole at any time or in part from
time to time,  _____,  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
Program,  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  Program,  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.

                                                                         Page 15

     6. Termination of Employment.

          6.1  Death,  Disability,  Retirement,  or  Change in  Control.  If the
employment of the Optionee is  terminated as a result of his death,  Disability,
Retirement,  or within two (2) years  following a Change in Control,  the Option
shall continue to be exercisable in whole or in part (to the extent  exercisable
on the date of the  Optionee's  termination  of  employment)  at any time within
three (3) years  after the date of such  termination  of  employment,  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 Program
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.

          6.2 Other Termination of Employment. If the employment of the Optionee
is  terminated  for any reason  other than the  reasons set forth in Section 6.1
(including the Optionee's  ceasing to be employed by a Subsidiary or Division as
a result of the sale of such  Subsidiary  or  Division  or an  interest  in such
Subsidiary  or  Division),  the  Option  shall  terminate  on  the  date  of the
Optionee's termination of employment, whether or not exercisable.

     7. Effect of Change in Control.

          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.

     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  Program  shall be  interpreted  or
construed to confer upon the Optionee any right with respect to  continuance  of
employment by the Company,  nor shall this Agreement or the Program interfere in
any way with the right of the Company 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 Program and shall be effective  and final,
binding, and conclusive for all purposes of the Program 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 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
on the date preceding the Tax Date (as defined  below) equal to the  Withholding
Taxes,  provided  that (i) if the  Optionee  may be subject to  liability  under
Section 16(b) of the Exchange Act (unless his or her  employment  was terminated
due to  Disability or death),  (A) the Optionee  makes the Tax Election at least
six (6) months  after the Grant Date and (B) the Tax  Election is made either at
least six (6) months prior to the date that the amount of the Withholding  Taxes
are determined  (the "Tax Date") or during the ten (10) day period  beginning on
the third  business  day and ending on the twelfth  business day  following  the
release for publication of the Company's quarterly or annual statements of

                                                                         Page 17

          earnings,  (ii) the Tax  Election  is made prior to the Tax Date,  and
(iii) the Tax Election is irrevocable;  provided, however, in the event that the
Tax Date occurs  subsequent  to the exercise of the Option,  the Optionee  shall
tender back to the  Company on the Tax Date that number of Shares  having a Fair
Market value on the date preceding the Tax Date equal to the Withholding Taxes.

          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
(2) year period commencing on the day after the Grant Date or within the one (1)
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.

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.
