The following documents, which are on file with the Securities and Exchange Commission , are incorporated in this Registration Statement by reference:

(b)

All documents filed by the Registrant with the Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act (excluding information deemed to be furnished and not filed with the Commission) subsequent to the effective date of this Registration Statement and prior to the filing of a post-effective amendment that indicates that all securities offered have been sold or that deregisters all securities then remaining unsold, will be deemed to be incorporated by reference in this Registration Statement and to be part hereof from the date of filing of such documents.

Any such statement so modified or superseded will not be deemed, except as modified or superseded, to constitute a part of this Registration Statement.

Item 6. Indemnification of Directors and Officers.

The corporate laws of British Columbia allow the Registrant, and its corporate articles require it (subject to the provisions of the Business Corporations Act (the "BCBCA") noted below), to indemnify its directors, former directors, alternate directors and their heirs and legal personal representatives against all eligible penalties to which such person is or may be liable, and the Registrant must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Each director and alternate director is deemed to have contracted with the Registrant on the terms of the indemnity contained in the Registrant's articles.

For the purposes of such an indemnification:

●

"associated corporation" means a corporation or entity referred to in paragraph (2) or (3) of the definition of "eligible party";

●

"eligible party" in relation to the Registrant, means an individual who:

(1)

is or was a director or officer of the Registrant;

(2)

is or was a director or officer of another corporation:

(i)

at a time when the corporation is or was an affiliate of the Registrant; or

(ii)

at the request of the Registrant; or

(3)

at the request of the Registrant, is or was, or holds or held a position equivalent to that of, a director or officer of a partnership, trust, joint venture or other unincorporated entity; and includes, except in the definition of "eligible proceeding" and certain other cases, the heirs and personal or other legal representatives of that individual.

●

"eligible penalty" means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, an eligible proceeding;

●

"eligible proceeding" means a proceeding in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the Registrant or an associated corporation:

(1)

is or may be joined as a party; or

(2)

is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding;

●

"expenses" includes costs, charges and expenses, including legal and other fees, but does not include judgments, penalties, fines or amounts paid in settlement of a proceeding; and

●

"proceeding" includes any legal proceeding including a civil, criminal, quasi-criminal, administrative or regulatory action or proceedings; or investigative action, whether current, threatened, pending or completed.

In addition, under the BCBCA, the Registrant may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in respect of that proceeding, provided that the Registrant first receives from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited by the restrictions noted below, the eligible party will repay the amounts advanced.

Notwithstanding the provisions of the Registrant's articles noted above, the Registrant must not indemnify an eligible party or pay the expenses of an eligible party, if any of the following circumstances apply:

●

if the indemnity or payment is made under an earlier agreement to indemnify or pay expenses and, at the time that the agreement to indemnify or pay expenses was made, the Registrant was prohibited from giving the indemnity or paying the expenses by its memorandum or articles;

●

if the indemnity or payment is made otherwise than under an earlier agreement to indemnify or pay expenses and, at the time that the indemnity or payment is made, the Registrant is prohibited from giving the indemnity or paying the expenses by its memorandum or articles;

●

if, in relation to the subject matter of the eligible proceeding, the eligible party did not act honestly and in good faith with a view to the best interests of the Registrant or the associated corporation, as the case may be; or

●

in the case of an eligible proceeding other than a civil proceeding, if the eligible party did not have reasonable grounds for believing that the eligible party's conduct in respect of which the proceeding was brought was lawful.

In addition, if an eligible proceeding is brought against an eligible party by or on behalf of the Registrant or by or on behalf of an associated corporation, the Registrant must not do either of the following:

●

indemnify the eligible party under Section 160(a) of the BCBCA in respect of the proceeding; or

●

pay the expenses of the eligible party in respect of the proceeding.

Notwithstanding any of the foregoing, and whether or not payment of expenses or indemnification has been sought, authorized or declined under the BCBCA or the articles of the Registrant, on the application of the Registrant or an eligible party, the Supreme Court of British Columbia may do one or more of the following:

●

order the Registrant to indemnify an eligible party against any liability incurred by the eligible party in respect of an eligible proceeding;

●

order the Registrant to pay some or all of the expenses incurred by an eligible party in respect of an eligible proceeding;

●

order the enforcement of, or any payment under, an agreement of indemnification entered into by the Registrant;

●

order the Registrant to pay some or all of the expenses actually and reasonably incurred by any person in obtaining an order under Section 164 of the BCBCA; or

●

make any other order the court considers appropriate.

Furthermore, the Registrant has entered into an indemnification agreement with each of its directors and executive officers. The indemnification agreements provide that the Registrant will, to the fullest extent possible under applicable law, subject to other specified limitations, indemnify and hold harmless the directors and executive officers against any and all costs and expenses reasonably incurred for, or in connection with, any civil, criminal, administrative, investigative or other proceeding, whether threatened, pending, continuing or completed, including but not limited to any act, matter, deed or thing whatsoever made, done, committed, permitted or acquiesced in.

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. 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 Filing Fee Tables" or "Calculation of Registration Fee" table, as applicable, in the effective 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) do not apply if 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 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)

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 Section 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.

(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 of 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.
