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.</TD>

Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.

Item 6. Indemnification of Directors and Officers.
Section 124 of the Canada Business Corporations Act authorizes corporations to indemnify past
and present directors, officers and certain other individuals for liabilities incurred in
connection with their services as such (including costs, expenses and settlement payments) if such
individual acted honestly and in good faith with a view to the best interests of the corporation
and, in the case of a criminal or administrative proceeding, if such individual had reasonable
grounds for believing his or her conduct was lawful. In the case of a suit by or on behalf of the
corporation, a court must approve the indemnification.
Section 11(4) of the Registrant's bylaws provides that the Registrant shall indemnify
directors and officers to the extent required or permitted by law.
The Registrant has entered into agreements with its directors and officers (each an
"Indemnitee" under such agreements) to indemnify the Indemnitee, to the extent permitted by law and
subject to certain limitations, against all costs reasonably incurred by an Indemnitee in an action
or proceeding to which the Indemnitee was made a party
by reason of the Indemnitee being an officer or director of (i) the Registrant or (ii) an
organization of which the Registrant is a shareholder or creditor if the Indemnitee serves such
organization at the request of the Registrant.
The Registrant maintains insurance policies relating to certain liabilities that its directors
and officers may incur in such capacity.

(2)
That, for the purpose of determining any liability under the Securities Act,

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.
(6)
That, for the purpose of determining liability of the Registrant under the
Securities Act to any purchaser in the initial distribution of the securities:

undersigned Registrant;
(iii)
The portion of any other free writing prospectus relating to
the offering containing material information about the undersigned Registrant
or its securities provided by or on behalf of the undersigned Registrant; and
(iv)
Any other communication that is an offer in the offering made

(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.
(h)
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.
