         The following documents filed with the Securities and Exchange
Commission are incorporated herein by reference:

              (a)  The prospectus constituting part of the Registration
         Statement on Form S-4 of Cantel Industries, Inc. (the "Company"),
         filed December 4, 1995 (Registration No. 33-6472), as amended by
         Amendment No. 1 filed January 26, 1996, Amendment No. 2 filed on

              (b)  The Annual Report of the Company for the fiscal year
         ended July 31, 1995 filed pursuant to Section 13(a) or 15(d) of
         the Securities Exchange Act of 1934.

              (c)  All other reports of the Company filed pursuant to
         Section 13(a) or 15(d) of the Securities Exchange Act of 1934
         since the end of the fiscal year ended July 31, 1995.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         None.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Restated Certificate of Incorporation of the Company sets forth
the extent to which officers or directors of the Company may be insured or
indemnified against any liabilities which they may incur.  The general effect of
such provision is that any person made a party to any action, suit or proceeding
by reason of the fact that he or she is or was a director, officer, employee or
agent of the Company, or of another corporation or other enterprise for which he
or she served as such at the request of the Company, shall be indemnified by the
Company against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding, provided, however, that no such
director, officer or employee shall be entitled to claim such indemnity (a) with
respect to any matter as to which there shall have been a final adjudication
that he or she is liable for willful misfeasance, bad faith, negligence or
misconduct in the performance of his or her duties as director, officer or
employee, or (b) with respect to any matter which shall be the subject of such
action, suit or proceeding disposed of otherwise than by adjudication on the
merits, unless in relation to such matter such director, officer or employee was
not liable for willful misfeasance, bad faith, negligence or misconduct in the
performance of his or her duties as director, officer or employee.

         The Company's Restated Certificate of Incorporation further provides
that the determination as to the right to indemnity of any director, officer or
employee in respect of any settlement in which the existence of willful
misfeasance, bad faith, negligence or misconduct in the performance of his or
her duties as director, officer or employee is not established, shall be made by
vote of two-thirds of those members of the Board of Directors not involved in
such action, suit or proceeding if such directors constitute a majority of the
members of the Board of Directors.  In the event that a majority of the members
of the Board of Directors are involved in such action, suit or proceeding,
indemnification shall be made if independent legal counsel shall give its
written opinion to the effect that the person to be indemnified is not liable
for willful misfeasance, bad faith, negligence or misconduct in the performance
of his or her duties as director, officer or employee.  The amount of such
reimbursement payable by the Company shall not exceed the costs and expenses
such indemnified person would have reasonably incurred if the action, suit or
proceeding had been litigated to a final conclusion.  The foregoing right of
indemnification shall not be deemed exclusive of any other rights to which any
such director, officer or employee may otherwise be entitled and shall inure to
the benefit of the heirs, executors and administrators of such director, officer
or employee.

                                        - 3 -

<PAGE>


         The Company maintains insurance for the benefit of its directors and
officers and the directors and officers of its subsidiaries, insuring such
persons against certain liabilities, including liabilities arising under the
securities laws.  In addition, the Company has entered into Indemnification
Agreements with each of its directors and certain of its officers which provide
for indemnification from liability to the full extent permitted by the Delaware
General Corporation Law.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, may be permitted to directors, officers or persons
controlling the Company pursuant to the foregoing provisions, the Company has
been informed that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is therefore unenforceable.  Furthermore, the Company has given
certain undertakings with respect to indemnification in connection with this
Registration Statement.

being made, a post-effective amendment to this Registration Statement 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.

              (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.

                                        - 5 -

<PAGE>


         (b)  The undersigned Company hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Company'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
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the Company pursuant to the foregoing provisions, or otherwise, the
Company 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 payment by the Company of expenses paid or
incurred by a director, officer or controlling person of the Company 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 Company 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.

              (a)  The prospectus constituting part of the Registration
         Statement on Form S-4 of Cantel Industries, Inc. (the "Company"),
         filed December 4, 1995 (Registration No. 33-6472), as amended by

to the filing of a post-effective amendment indicating that all securities
offered hereby have been sold or deregistering all such securities then unsold,
shall be deemed to be incorporated by reference into this Registration Statement
and to be a part hereof from the date of filing of such documents.

                                        - 2 -
ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         None.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Restated Certificate of Incorporation of the Company sets forth
the extent to which officers or directors of the Company may be insured or
indemnified against any liabilities which they may incur.  The general effect of
such provision is that any person made a party to any action, suit or proceeding
by reason of the fact that he or she is or was a director, officer, employee or
agent of the Company, or of another corporation or other enterprise for which he
or she served as such at the request of the Company, shall be indemnified by the
Company against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding, provided, however, that no such
director, officer or employee shall be entitled to claim such indemnity (a) with
respect to any matter as to which there shall have been a final adjudication
that he or she is liable for willful misfeasance, bad faith, negligence or
misconduct in the performance of his or her duties as director, officer or
employee, or (b) with respect to any matter which shall be the subject of such
action, suit or proceeding disposed of otherwise than by adjudication on the
merits, unless in relation to such matter such director, officer or employee was
not liable for willful misfeasance, bad faith, negligence or misconduct in the
performance of his or her duties as director, officer or employee.

         The Company's Restated Certificate of Incorporation further provides
that the determination as to the right to indemnity of any director, officer or
employee in respect of any settlement in which the existence of willful
misfeasance, bad faith, negligence or misconduct in the performance of his or
her duties as director, officer or employee is not established, shall be made by
vote of two-thirds of those members of the Board of Directors not involved in
such action, suit or proceeding if such directors constitute a majority of the
members of the Board of Directors.  In the event that a majority of the members
of the Board of Directors are involved in such action, suit or proceeding,
indemnification shall be made if independent legal counsel shall give its
written opinion to the effect that the person to be indemnified is not liable
for willful misfeasance, bad faith, negligence or misconduct in the performance
of his or her duties as director, officer or employee.  The amount of such
reimbursement payable by the Company shall not exceed the costs and expenses
such indemnified person would have reasonably incurred if the action, suit or
proceeding had been litigated to a final conclusion.  The foregoing right of
indemnification shall not be deemed exclusive of any other rights to which any
such director, officer or employee may otherwise be entitled and shall inure to
the benefit of the heirs, executors and administrators of such director, officer
or employee.

                                        - 3 -
The Company maintains insurance for the benefit of its directors and
officers and the directors and officers of its subsidiaries, insuring such
persons against certain liabilities, including liabilities arising under the
securities laws.  In addition, the Company has entered into Indemnification
Agreements with each of its directors and certain of its officers which provide
for indemnification from liability to the full extent permitted by the Delaware
General Corporation Law.

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, may be permitted to directors, officers or persons
controlling the Company pursuant to the foregoing provisions, the Company has
been informed that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is therefore unenforceable.  Furthermore, the Company has given
certain undertakings with respect to indemnification in connection with this
Registration Statement.

ITEM 9.  UNDERTAKINGS.

         (a)  The undersigned Company hereby undertakes:

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

              (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.

                                        - 5 -
(b)  The undersigned Company hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Company'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
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the Company pursuant to the foregoing provisions, or otherwise, the
Company 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 payment by the Company of expenses paid or
incurred by a director, officer or controlling person of the Company 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 Company 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.
