                or having been a director, including an action brought by the
                company or corporation, if

                (a)     the person acted honestly and in good faith with a view
                        to the best interests of the corporation of which the
                        person is or was a director, and

                (b)     in the case of a criminal or administrative action or
                        proceeding, the person had reasonable grounds for
                        believing that the person's conduct was lawful.

        (2)     The court, on the application of a company, director or a former
                director, may make an order approving an indemnity under this
                section, and the court may make any further order it considers
                appropriate.

        (3)     On an application under subsection (2), the court may order
                notice to be given to any interested person.

        (4)     A company may purchase and maintain insurance for the benefit of
                a person referred to in this section against any liability
                incurred by the person as a director or officer.

        (5)     Subsections (1) to (3) apply to officers or former officers of a
                company or of a corporation of which the company is or was a
                shareholder.

        The Articles of the Company provide that:

        23.1    (1)     Subject to the provisions of the Company Act, the
                        Company shall indemnify a director or former director of
                        the Company and a director or a former director of a
                        corporation of which the Company is or was a
                        shareholder, and the heirs and personal representatives
                        of any such director or former director, against all
                        costs, charges and expenses, including an


                                      -2-
<PAGE>   4
                        amount paid to settle an action or satisfy a judgment,
                        actually and reasonably incurred by him, including an
                        amount paid to settle an action or satisfy a judgment in
                        a civil, criminal or administrative action or proceeding
                        to which the person is made a party by reason of being
                        or having been a director of the Company or a director
                        of such corporation, including any action brought by the
                        Company or corporation if (a) the person acted honestly
                        and in good faith with a view to the best interests of
                        the Company or the corporation of which the person is or
                        was a director, and (b) in the case of a criminal or
                        administrative action or proceeding, the person had
                        reasonable grounds for believing that his conduct was
                        lawful.

                (2)     The determination of any action, suit or proceeding by
                        judgment, order, settlement, conviction or otherwise
                        shall not, of itself, create a presumption that the
                        person did not so act or did not have reasonable
                        grounds, as aforesaid.

                (3)     Each director of the Company upon being elected or
                        appointed shall be deemed to have contracted with the
                        Company on the terms of the foregoing indemnity.

        23.2    The Company shall indemnify an officer or former officer of the
                Company and an officer or former officer of a corporation of
                which the Company is or was a shareholder, and the heirs and
                personal representatives of any such officer or former officer,
                to the full extent permitted by the Company Act.

        23.3    (1)     The indemnification provided by this Part shall not be
                        deemed exclusive of any other rights to which those
                        seeking indemnification may be entitled under any other
                        Part, or any valid and lawful agreement, vote of members
                        or disinterested directors or otherwise, or under the
                        provisions of any statute now or hereafter existing,
                        both as to action in the official capacity of such
                        person and as to action in another capacity while
                        holding such office, and shall continue as to a person
                        who has ceased to be a director, officer, employee or
                        agent and shall enure to the benefit of the heirs and
                        personal representatives of such person.

                (2)     The indemnification provided by this Part shall not be
                        exclusive of any powers, rights, agreements or
                        undertakings which may be legally permissible or
                        authorized by or under any applicable law.

                (3)     Notwithstanding any other provisions set forth in this
                        Part, the indemnification authorized by this Part shall
                        be applicable only to the extent that any such
                        indemnification shall not duplicate indemnity or
                        reimbursement which that person has received or shall
                        receive otherwise than under this Part.

        23.4    The directors are authorized from time to time to cause the
                Company to give indemnities to any director, officer, employee,
                agent or other person who has undertaken or is about to
                undertake any liability on behalf of the Company or any
                corporation of which it is a shareholder.

        A policy of directors' and officers' liability insurance is maintained
by the Company which insures directors and officers for losses as a result of
claims against the directors and officers of the Company in their capacity as
directors and officers and also reimburses the Company for payments made
pursuant to the indemnity provisions under the Articles and the BCCA.

        Insofar as indemnification for liabilities under the Securities Act of
1933 (the "Securities Act") may be permitted to directors, officers or persons
controlling the Company pursuant to the foregoing provisions, the Company has
been advised that in the opinion of the Commission such indemnification is
against public policy in the United States as expressed in the Securities Act
and is therefore unenforceable.

        The undersigned registrant hereby undertakes to submit the Plan and any

manner and that the registrant will make all changes required by the IRS in
order to qualify the plan under section 401 of the Internal Revenue Code and to
maintain such qualification.

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 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 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.

        (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 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.
