herein by reference:

          (a) The Registrant's latest annual report filed pursuant to Section
     13(a) or 15(d) of the Securities Exchange Act of 1934 or the latest
     prospectus filed pursuant to rule 424(b) under the Securities Act of 1933

     All reports and other documents subsequently filed by the Registrant
pursuant to Sections 13(a) and (c), 14 and 15(d) of the Securities Exchange Act
of 1934, as amended, prior to the filing of a post-effective amendment which

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not Applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Reference is made to Section 145 of the General Corporation Law of the
State of Delaware (the "DGCL"), which provides for indemnification of directors,

Company, as amended, eliminates the personal liability for monetary damages of
directors under certain circumstances. The by-laws of the Company provide
indemnification to directors, officers and other employees of the Company to the
fullest extent permitted by the DGCL. The Company has also executed
indemnification agreements with the directors, officers and certain other
employees of the Company. Such indemnification agreements contain provisions
which purport to provide indemnification, where not limited by applicable law,
for amounts paid by such individuals in settlement of shareholder derivative
actions. Additionally, the Company maintains customary directors' and officers'
liability insurance protecting officers and directors against certain
liabilities which they may incur in their capacities as such.

     24.1 Form of Power of Attorney

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;

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

     PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) 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.


                                      II-2

<PAGE>

          (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.

     (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 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 foregoing provisions, 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.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents filed by Allied Healthcare Products, Inc. (the
"Registrant") with the Securities and Exchange Commission are incorporated
herein by reference:

          (a) The Registrant's latest annual report filed pursuant to Section
     13(a) or 15(d) of the Securities Exchange Act of 1934 or the latest
     prospectus filed pursuant to rule 424(b) under the Securities Act of 1933
     that contains audited financial statements for the Registrant's latest
     fiscal year for which such statements have been filed.

          (b) All other reports filed pursuant to Section 13(a) or 15(d) of the
     Securities Exchange Act of 1934 since the end of the fiscal year covered by
     the annual report or prospectus referred to in (a) above.

          (c) The description of the authorized capital stock of the Registrant
     contained in the Registrant's registration statements filed under Section
     12 of the Securities Exchange Act of 1934, as amended, including any
     amendment or report filed for the purpose of updating the description.

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

ITEM 4. DESCRIPTION OF SECURITIES.

     Not Applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not Applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Reference is made to Section 145 of the General Corporation Law of the
State of Delaware (the "DGCL"), which provides for indemnification of directors,
officers and other employees in certain circumstances, and to Section 102(b)(7)
of the DGCL, which provides for the elimination or limitation of the personal
liability for monetary damages of directors under certain circumstances. The
Restated Certificate of Incorporation of the

                                      II-1
Company, as amended, eliminates the personal liability for monetary damages of
directors under certain circumstances. The by-laws of the Company provide
indemnification to directors, officers and other employees of the Company to the
fullest extent permitted by the DGCL. The Company has also executed
indemnification agreements with the directors, officers and certain other
employees of the Company. Such indemnification agreements contain provisions
which purport to provide indemnification, where not limited by applicable law,
for amounts paid by such individuals in settlement of shareholder derivative
actions. Additionally, the Company maintains customary directors' and officers'
liability insurance protecting officers and directors against certain
liabilities which they may incur in their capacities as such.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not Applicable.

     24.1 Form of Power of Attorney

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;

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

     PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) 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.

                                      II-2
(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.

     (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 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 foregoing provisions, 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.

                                      II-3
