individual for the costs, charges and expenses of a proceeding referred to
above. The individual shall repay the moneys if the individual does not fulfil
the conditions in (a) and (b) below. The Registrant may not indemnify an
individual unless the individual (a) acted honestly and in good faith with a

above. Notwithstanding the foregoing, an individual is entitled to indemnity
from the Registrant in respect of all costs, charges and expenses, reasonably
incurred by the individual in the defense of any civil, criminal, administrative
or other proceeding to which the individual is subject because of the
individuals association with the Registrant or other entity referred to above,
if the individual seeking indemnity was not judged by a court or other competent
authority to have committed any fault or omitted to do anything that the
individual ought to have done, and if the individual fulfils the conditions set
out in (a) and (b) above.

          A by-law of the Registrant provides 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 a corporate body of which the Registrant is or was a
shareholder or creditor, and the heirs and legal representatives thereof, to the
extent permitted by the Canada Business Corporations Act ("CBCA") or otherwise
by law.

          The Registrant maintains a directors' and officers' liability policy
which provides coverage to the Registrant for all directors' and officers'
related claims, losses and cost in any year, subject to policy limits and
deductibles.


                                       5



          The Registrant has entered into indemnification agreements with each
of its officers and directors pursuant to which they are indemnified to the
fullest extent permitted by the CBCA. Pursuant to the terms of these agreements

directors while they remain an officer or director and for a period of 10 years
thereafter.

               (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;

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

                   (iii) To include any material information with respect to

               PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) shall
               not apply to information contained in periodic reports filed by

               (2)  That, for the purpose of determining any liability under the
                    Securities Act, each such post-effective amendment shall be
                    deemed to be a new registration statement relating to the

               (3)  To remove from registration by means of a post-effective
                    amendment any of the securities being registered that remain

          (b)  The undersigned Registrant hereby undertakes that, for purposes
               of determining any liability under the Securities Act, each
               filing of the Registrant's Annual Report pursuant to section
               13(a) or 15(d) of the Exchange Act (and, where applicable, each
               filing of an employee benefit plan's annual report pursuant to
               Section 15(d) of the Exchange Act) 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.

               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
               Securities 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 Securities Act and will be governed by the final adjudication
               of such issue.
