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

policy as expressed in the Securities Act and will be governed by the final adjudication of
such issue.</TD>

The following documents previously filed by the Registrant with the Securities and Exchange
Commission (the "Commission") are incorporated by reference in this Registration Statement:

In addition, all of the Registrant's reports filed with the Commission pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
after the date of this Registration Statement and prior to filing a post-effective amendment which
indicates that all securities offered hereby have been sold or which deregisters all securities
then remaining unsold shall be deemed to be incorporated by reference in this Registration
Statement and to be a part hereof from the date of filing of such reports.
Any statement contained herein or in a document incorporated or deemed to be incorporated by
reference herein shall be deemed to be modified or superseded for purposes of this Registration
Statement to the extent that a statement contained in any subsequently filed document which also is
or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
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.
Table of Contents
The Registrant maintains insurance policies relating to certain liabilities that its directors
and officers may incur in such capacity.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index.
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:
(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 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; and
(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) of this section do not apply
if the Registration Statement is on
Form
S-8,
and the information required to be
included in a post-effective amendment by those paragraphs is contained in reports filed
with or furnished to the Commission by the registrant pursuant to section 13 or section
15(d) of the Exchange Act 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 those 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.
(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:
The undersigned Registrant undertakes that in a primary offering of securities of the
undersigned Registrant pursuant to this Registration Statement, regardless of the
underwriting method used to sell the securities to the purchaser, if the securities are
offered or sold to such purchaser by means of any of the following communications, the
undersigned Registrant will be a seller to the purchaser and will be considered to offer
or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned
Registrant relating to the offering required to be filed pursuant to Rule 424;
Table of Contents
(ii)
any free writing prospectus relating to the offering prepared
by or on behalf of the undersigned Registrant or used or referred to by the
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
by the undersigned Registrant to the purchaser.
(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.
