ITEM 6: INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 124 of the Canada Business Corporations Act ("CBCA") and
Section 7 of the Registrant's General By-Law No. 1 provide for the
indemnification of directors and officers of the Registrant. Under these
provisions, the Registrant shall indemnify a director or officer of the
Registrant (or a former director or officer) against all costs, charges and
expenses, including amounts paid to settle an action or satisfy a judgment,
reasonably incurred by such director or officer in respect of any civil,
criminal or administrative action or proceeding (other than in respect of an
action by or on behalf of the Registrant to procure a judgment in its favor) to
which such director or officer (or a former director or officer) is made a party
by reason of his position with the Registrant, if he or she fulfils the
following two conditions: (a) he or she acted honestly and in good faith with a
view to the best interests of the Registrant 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. In respect of an action by or on behalf of the Registrant to procure a
judgment in its favor, the Registrant with the approval of a court may indemnify
a director or officer of the Registrant (or a former director or officer)
against all costs, charges and expenses reasonably incurred by him or her in
connection with such action if he or she fulfils the conditions set out in the
clauses (a) and (b) of the previous sentence. Notwithstanding the foregoing, a
director or officer of the Registrant (or a former director or officer) is
entitled to indemnification from the Registrant in respect of all costs, charges
and expenses incurred by him or her in connection with the defense of any civil
criminal or administrative action or proceeding to which he or she is made a
party by reason of his or her position with the Registrant if he or she was
substantially successful on the merits in his or her defense of the action or
proceeding and he or she fulfills the conditions in clauses (a) and (b) of the
second sentence in this paragraph.

          Section 7.4 of the Registrant's By-Law No. 1 also provides that so
long as the directors and officers act honestly and in good faith, to the extent
permitted by law, the Registrant will indemnify the directors and officers from
any liability incurred for: (i) acts or neglects of other directors and
officers; (ii) loss, damage, or expense due to insufficiency or deficiency of
title of property acquired by the Registrant, due to investment of the
Registrant's assets in insufficient or deficient securities, due to acts of
those holding the Registrant's assets, or from any other dealings with any
assets belonging to the Registrant; or (iii) any other loss, damage, or
misfortune which may happen in the execution of the officers' or directors'
respective duties.

          The Registrant maintains directors' and officers' liability insurance
with an aggregate policy limit of U.S. $70 million subject to a deductible of
U.S. $100,000 for each claim other than U.S. securities law claims and U.S.
$500,000 in respect of U.S. securities law claims.

ITEM 9: UNDERTAKINGS.

          (a) 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:

                    (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 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 forth in this 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 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.


                                                                               5

<PAGE>

                    (iii) To include any material information with respect to
               the plan of distribution not previously disclosed in this
               Registration Statement or any material change to such information
               in the Registration Statement;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) shall
          not apply if 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 the Registrant
          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, 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; and

               (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 Registrant hereby undertakes that, for purposes of determining
liability under the Securities Act, each filing of the Registrant's annual
report on Form 10-K pursuant to Section 13(a) or Section 15(d) of the Exchange
Act (and each filing of an employee benefit plan annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
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 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 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.


                                                                               6

requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly

ITEM 6: INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 124 of the Canada Business Corporations Act ("CBCA") and
Section 7 of the Registrant's General By-Law No. 1 provide for the
indemnification of directors and officers of the Registrant. Under these
provisions, the Registrant shall indemnify a director or officer of the
Registrant (or a former director or officer) against all costs, charges and
expenses, including amounts paid to settle an action or satisfy a judgment,
reasonably incurred by such director or officer in respect of any civil,
criminal or administrative action or proceeding (other than in respect of an
action by or on behalf of the Registrant to procure a judgment in its favor) to
which such director or officer (or a former director or officer) is made a party
by reason of his position with the Registrant, if he or she fulfils the
following two conditions: (a) he or she acted honestly and in good faith with a
view to the best interests of the Registrant 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. In respect of an action by or on behalf of the Registrant to procure a
judgment in its favor, the Registrant with the approval of a court may indemnify
a director or officer of the Registrant (or a former director or officer)
against all costs, charges and expenses reasonably incurred by him or her in
connection with such action if he or she fulfils the conditions set out in the
clauses (a) and (b) of the previous sentence. Notwithstanding the foregoing, a
director or officer of the Registrant (or a former director or officer) is
entitled to indemnification from the Registrant in respect of all costs, charges
and expenses incurred by him or her in connection with the defense of any civil
criminal or administrative action or proceeding to which he or she is made a
party by reason of his or her position with the Registrant if he or she was
substantially successful on the merits in his or her defense of the action or
proceeding and he or she fulfills the conditions in clauses (a) and (b) of the
second sentence in this paragraph.

          Section 7.4 of the Registrant's By-Law No. 1 also provides that so
long as the directors and officers act honestly and in good faith, to the extent
permitted by law, the Registrant will indemnify the directors and officers from
any liability incurred for: (i) acts or neglects of other directors and
officers; (ii) loss, damage, or expense due to insufficiency or deficiency of
title of property acquired by the Registrant, due to investment of the
Registrant's assets in insufficient or deficient securities, due to acts of
those holding the Registrant's assets, or from any other dealings with any
assets belonging to the Registrant; or (iii) any other loss, damage, or
misfortune which may happen in the execution of the officers' or directors'
respective duties.

          The Registrant maintains directors' and officers' liability insurance
with an aggregate policy limit of U.S. $70 million subject to a deductible of
U.S. $100,000 for each claim other than U.S. securities law claims and U.S.
$500,000 in respect of U.S. securities law claims.

ITEM 9: UNDERTAKINGS.

          (a) 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:

                    (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 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 forth in this 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 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.

                                                                               5
(iii) To include any material information with respect to
               the plan of distribution not previously disclosed in this
               Registration Statement or any material change to such information
               in the Registration Statement;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) shall
          not apply if 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 the Registrant
          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, 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; and

               (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 Registrant hereby undertakes that, for purposes of determining
liability under the Securities Act, each filing of the Registrant's annual
report on Form 10-K pursuant to Section 13(a) or Section 15(d) of the Exchange
Act (and each filing of an employee benefit plan annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in this
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 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 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.

                                                                               6

          Pursuant to the requirements of the Securities Act, the Registrant

requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of New York, State of New York, on June 7, 2006.
