ITEM 5.   Interests of Named Experts and Counsel.

          Not applicable.

ITEM 6.   Indemnification of Directors and Officers.

          Under  the  Ontario  Business   Corporations   Act  (the  "OBCA"),   a
     corporation  may  indemnify a director or officer of the  corporation  or a
     person who acts or acted at the  corporation's  request  as a  director  or
     officer  of a  body  corporate  of  which  the  corporation  is  or  was  a
     shareholder or creditor against all costs, charges and expenses,  including
     an  amount  paid to settle an  action  or  satisfy a  judgment,  reasonably
     incurred by him or her in respect of any civil,  criminal or administrative
     action or  proceeding to which he or she is made a party by reason of being
     or having been a director or officer of that corporation or body corporate,
     if (a) he or she acted  honestly  and in good faith with a view to the best
     interests  of the  corporation,  and  (b)  in the  case  of a  criminal  or
     administrative action or proceeding that is enforced by a monetary penalty,
     he or she had reasonable  grounds for believing that his or her conduct was
     lawful.  Where that  action is by or on behalf of the  corporation  or that
     body corporate, the approval of the court is also required.

          In accordance  with the OBCA,  the By-laws of the  Registrant  provide
     that  the  Registrant   shall  indemnify  a  director  or  officer  of  the
     Registrant,  a former director or officer of the Registrant or a person who
     acts or acted at the  Registrant's  request,  as a  director  or officer of
     another  corporation  of which the  Registrant is or was a  stockholder  or
     creditor,  and the heirs and legal  representatives of such a person to the
     extent permitted under the OBCA.

          A policy of directors' and officers' liability insurance is maintained
     by the  Registrant  which insures  directors and officers of the Registrant
     for losses as a result of claims  based upon  their  acts or  omissions  as
     directors and officers,  including  liabilities under the Securities Act of
     1933, and also  reimburses the Registrant for payments made pursuant to the
     indemnity provisions under the OBCA.

ITEM 7.   Exemption from Registration Claimed.

          Not Applicable.

(1)  Incorporated by reference from the Registrant's  Registration  Statement on
Form S-8 (File No. 333-9576) as filed with the Commission on November 3, 1998.

ITEM 9.   Undertakings.

          The 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 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.

          The undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  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 this
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.


                                      II-3





          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 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.

Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized,  in the Town of Markham,  Province of Ontario, Country of Canada, on
