         All other documents filed by the registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act
of 1934 after the date of filing of this Registration Statement and prior to the filing of a post-effective amendment which indicates
that all securities offered hereby have been sold, or which deregisters all securities then remaining unsold, shall be deemed to be
incorporated herein by reference and to be a part hereof from the date of filing of such documents.

Item 4. Description of Securities.
---------------------------------

         Omitted; inapplicable.

Item 5. Interests of Named Experts and Counsel.
----------------------------------------------

         Omitted; inapplicable.

Item 6. Indemnification of Directors and Officers.
-------------------------------------------------

         Section 145 of the Delaware General Corporation Law ("Section 145") generally provides that a director or officer of a
corporation:  (i) shall be indemnified by the corporation for expenses in defense of any action or proceeding in connection with his
service to the corporation, if he is successful in defense of the claims made against him; (ii) may, in actions other than
"derivative" and similar actions, be indemnified for expenses, judgments and settlements even if he is not successful on the merits,
if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation
(and in a criminal proceeding, if he had no reasonable cause to believe his conduct was unlawful); and (iii) may be indemnified by
the corporation for expenses (but not judgments or settlements) incurred to defend or settle any action by the corporation or a
derivative action (such as a suit by a shareholder alleging a breach by the director or officer of a duty owed to the corporation),

Page 3

even if he is not successful, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, provided that no indemnification is permitted without court approval if the individual was
found to be liable to the corporation.  Before the permissive indemnification described in clauses (ii) and (iii) above may be made
pursuant to Section 145, either (i) a majority of disinterested directors, (ii) a committee of one or more disinterested directors
designated by a majority of disinterested directors, (iii) the stockholders, or (iv) under certain circumstances, independent legal
counsel in a written opinion, must determine that indemnification is appropriate in the circumstances because the applicable
standards of conduct have been met.

         Delaware law permits the advancement of expenses incurred by a proposed indemnitee by the corporation in advance of final
disposition of the action provided the indemnitee undertakes to repay such advanced expenses if it is ultimately determined that he
is not entitled to indemnification.  The corporation may purchase insurance on behalf of an indemnitee against any liability asserted
against him in his designated capacity, whether or not the corporation itself would be empowered to indemnify him against such
liability.

         Delaware law also provides that the above rights will not be deemed exclusive of other rights of indemnification or
advancement of expenses granted by by-law, agreement, vote of stockholders or disinterested directors or otherwise, as to action in
an indemnitee's official capacity and as to action in another capacity while holding such office.  The registrant's Certificate of
Incorporation and By-laws provide such additional rights.

         Article Fifteenth of the registrant's Certificate of Incorporation, which provides contractual indemnification rights, was
initially approved by the registrant's stockholders in 1987.  It provides for mandatory indemnification of directors and officers to
the full extent now authorized by the Delaware General Corporation Law (as described above) or to the further extent indemnification
under the Delaware General Corporation Law is broadened in the future.  Article Fifteenth also mandates advancement of expenses
incurred by a proposed indemnitee, provided that, as long as Delaware law so requires, an undertaking to repay (as described above)
is delivered to the registrant.

         Article Fifteenth permits persons indemnified thereunder to bring suit against the registrant to recover unpaid amounts
claimed thereunder, with the expense of bringing a successful suit to be paid by the registrant.  Article Fifteenth also provides
that rights conferred therein are nonexclusive and that the registrant may maintain insurance to protect a director or officer
against any expense, liability, or loss, whether or not the registrant had the power under the Delaware General Corporation Law to
indemnify such person against that expense, liability, or loss.

         Section 7.8 of the registrant's By-laws provides rights to indemnification with respect to conduct on or before January 5,
1987, when Article Fifteenth was initially adopted.  Section 7.8 provides indemnification rights which are similar to, but somewhat
narrower than, the rights extended by Article Fifteenth.

         The registrant's directors and officers are insured against losses arising from any claim against them in such capacities
for wrongful acts or omissions, subject to certain limitations.

Item 7. Exemption from Registration Claims.
------------------------------------------

         Omitted; inapplicable.

         Item 9. Undertakings.
         --------------------

         (a)      The undersigned registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales are being made, a post-effective amendment to this
registration statement:

                           (i)      To include any prospectus required by section 10(a)(3) of the
         Securities Act of 1933;

                           (ii)     To reflect in the prospectus any facts or events arising after the effective date of the
         registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate,
         represent a fundamental change in the information set forth in the registration statement; and

                           (iii)    To include any material information with respect to the plan of distribution not previously
         disclosed in the registration statement or any material change in such information in the registration statement;

provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) above do not apply if the information required to be included in a post-effective
--------- --------
amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of
the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

                  (2)      That, for the purpose of determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

                  (3)      To remove from registration by means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.

Page 5

         (b)      The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the registrant pursuant to the provisions described under Item 6, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such issue.

                                                              SIGNATURES
                                                              ----------

         Pursuant to the requirements of the Securities Act of 1933, the registrant, National Service Industries, Inc., certifies
that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Atlanta, State of
Georgia, on the 19th day of March, 2001.

         All other documents filed by the registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act
of 1934 after the date of filing of this Registration Statement and prior to the filing of a post-effective amendment which indicates
that all securities offered hereby have been sold, or which deregisters all securities then remaining unsold, shall be deemed to be
incorporated herein by reference and to be a part hereof from the date of filing of such documents.

Item 4. Description of Securities.
---------------------------------

         Omitted; inapplicable.

Item 5. Interests of Named Experts and Counsel.
----------------------------------------------

         Omitted; inapplicable.

Item 6. Indemnification of Directors and Officers.
-------------------------------------------------

         Section 145 of the Delaware General Corporation Law ("Section 145") generally provides that a director or officer of a
corporation:  (i) shall be indemnified by the corporation for expenses in defense of any action or proceeding in connection with his
service to the corporation, if he is successful in defense of the claims made against him; (ii) may, in actions other than
"derivative" and similar actions, be indemnified for expenses, judgments and settlements even if he is not successful on the merits,
if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation
(and in a criminal proceeding, if he had no reasonable cause to believe his conduct was unlawful); and (iii) may be indemnified by
the corporation for expenses (but not judgments or settlements) incurred to defend or settle any action by the corporation or a
derivative action (such as a suit by a shareholder alleging a breach by the director or officer of a duty owed to the corporation),

Page 3

even if he is not successful, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, provided that no indemnification is permitted without court approval if the individual was
found to be liable to the corporation.  Before the permissive indemnification described in clauses (ii) and (iii) above may be made
pursuant to Section 145, either (i) a majority of disinterested directors, (ii) a committee of one or more disinterested directors
designated by a majority of disinterested directors, (iii) the stockholders, or (iv) under certain circumstances, independent legal
counsel in a written opinion, must determine that indemnification is appropriate in the circumstances because the applicable
standards of conduct have been met.

         Delaware law permits the advancement of expenses incurred by a proposed indemnitee by the corporation in advance of final
disposition of the action provided the indemnitee undertakes to repay such advanced expenses if it is ultimately determined that he
is not entitled to indemnification.  The corporation may purchase insurance on behalf of an indemnitee against any liability asserted
against him in his designated capacity, whether or not the corporation itself would be empowered to indemnify him against such
liability.

         Delaware law also provides that the above rights will not be deemed exclusive of other rights of indemnification or
advancement of expenses granted by by-law, agreement, vote of stockholders or disinterested directors or otherwise, as to action in
an indemnitee's official capacity and as to action in another capacity while holding such office.  The registrant's Certificate of
Incorporation and By-laws provide such additional rights.

         Article Fifteenth of the registrant's Certificate of Incorporation, which provides contractual indemnification rights, was
initially approved by the registrant's stockholders in 1987.  It provides for mandatory indemnification of directors and officers to
the full extent now authorized by the Delaware General Corporation Law (as described above) or to the further extent indemnification
under the Delaware General Corporation Law is broadened in the future.  Article Fifteenth also mandates advancement of expenses
incurred by a proposed indemnitee, provided that, as long as Delaware law so requires, an undertaking to repay (as described above)
is delivered to the registrant.

         Article Fifteenth permits persons indemnified thereunder to bring suit against the registrant to recover unpaid amounts
claimed thereunder, with the expense of bringing a successful suit to be paid by the registrant.  Article Fifteenth also provides
that rights conferred therein are nonexclusive and that the registrant may maintain insurance to protect a director or officer
against any expense, liability, or loss, whether or not the registrant had the power under the Delaware General Corporation Law to
indemnify such person against that expense, liability, or loss.

         Section 7.8 of the registrant's By-laws provides rights to indemnification with respect to conduct on or before January 5,
1987, when Article Fifteenth was initially adopted.  Section 7.8 provides indemnification rights which are similar to, but somewhat
narrower than, the rights extended by Article Fifteenth.

         The registrant's directors and officers are insured against losses arising from any claim against them in such capacities
for wrongful acts or omissions, subject to certain limitations.

Item 7. Exemption from Registration Claims.
------------------------------------------

         Omitted; inapplicable.

changes required by the Service in order to qualify the Plan and obtain such letter.

         Item 9. Undertakings.
         --------------------

         (a)      The undersigned registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales are being made, a post-effective amendment to this
registration statement:

                           (i)      To include any prospectus required by section 10(a)(3) of the
         Securities Act of 1933;

                           (ii)     To reflect in the prospectus any facts or events arising after the effective date of the
         registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate,
         represent a fundamental change in the information set forth in the registration statement; and

                           (iii)    To include any material information with respect to the plan of distribution not previously
         disclosed in the registration statement or any material change in such information in the registration statement;

provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) above do not apply if the information required to be included in a post-effective
--------- --------
amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of
the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

                  (2)      That, for the purpose of determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

                  (3)      To remove from registration by means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.

Page 5

         (b)      The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act
of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the registrant pursuant to the provisions described under Item 6, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such issue.

                                                              SIGNATURES
                                                              ----------

         Pursuant to the requirements of the Securities Act of 1933, the registrant, National Service Industries, Inc., certifies
