          Not applicable.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 22 of the Bylaws of the Company provides, with regard to
indemnity and insurance under the Business Corporations Act of the Province of
New Brunswick, Canada (the "Act"), in part as follows:

          "Subject to 81 of the Act, except in respect of an action by or on
     behalf of the Corporation or Another Body Corporate (as hereinafter
     defined) to procure a judgement in its favour, the Corporation shall
     indemnify each director and officer of the Corporation and each former
     director and officer of the Corporation and each person who acts or acted
     at the Corporation's request as a director or officer of Another Body
     Corporate, and his heirs and legal representatives, against all costs,
     charges and expenses, including any amount paid to settle an action or
     satisfy a judgment, reasonably incurred by him in respect of any civil,
     criminal or administrative action or proceeding to which he is made a party
     by reason of being or having been a director or officer of the Corporation
     or Another Body Corporate, as the case may be, if

          (a)  he acted honestly and in good faith with a view to the best
               interests of the Corporation;


                                        2

               and

          (b)  in the case of a criminal or administrative action or proceeding
               that is enforced by a monetary penalty, he had reasonable grounds
               for believing that his conduct was lawful.

     "Another Body Corporate" as used herein means a body corporate of which the
     Corporation is or was a shareholder or creditor."

          The Act provides that no officer or director of the Company may be
indemnified in connection with the defense of any civil, criminal or
administrative action or proceeding to which such person is made a party by
reason of being or having been a director or officer of the corporation or body
corporate, unless a court of competent jurisdiction has approved the terms of
such indemnification. However, the Act further provides that notwithstanding any
provision to the contrary therein, any officer or director is entitled to
indemnification if such person (i) was substantially successful on the merits of
the defense of the action or proceeding; (ii) acted honestly and in good faith
with a view to the best interests of the corporation; and (iii) where a criminal
or administrative action or monetary penalty is involved, such person had
reasonable grounds for believing that his or her conduct was lawful.

          Insofar as indemnification for liabilities arising from 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 U.S. Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

          Not applicable.

ITEM 9. UNDERTAKINGS

(a)  We hereby undertake:

          (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. Notwithstanding the foregoing, any increase or
                    decrease in volume of securities offered (if the total
                    dollar value of securities offered would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of a prospectus filed with the Commission
                    pursuant to Rule 424(b) if, in the aggregate, the changes in
                    volume and price represent no more than a 20% change in the
                    maximum aggregate offering price set forth in the
                    "Calculation of Registration Fee" table in the effective
                    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 registration statement is on Form S-3, Form S-8 or Form F-3 and the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed with or furnished to the
     Commission by us 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.

          (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)  We hereby undertake that, for purposes of determining any liability under
     the Securities Act of 1933, each filing of our 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 benefits 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.

(h)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to our directors, officers and controlling persons
     pursuant to the foregoing provisions, or otherwise, we have been advised
     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. In the event that a claim for
     indemnification against such liabilities (other than the payment by us of
     expenses incurred or paid by a director, officer or controlling person 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, we will, unless in the opinion of our counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by us is
     against public policy as expressed in the Securities Act of 1933 and will
     be governed by the final adjudication of such issue.
