Business Corporations Act (British Columbia)

Division 5 of Part 5 of the Business Corporations Act (British Columbia) provides that a corporation may (a) indemnify an eligible party against all eligible penalties to which the eligible party is or may be liable and (b) after the final disposition of an eligible proceeding, pay the expenses (not including judgments, penalties, fines or amounts paid in settlement of a proceeding) actually and reasonably incurred by an eligible party in respect of that proceeding.

An “eligible party” means an individual who (a) is or was a director or officer of the corporation, (b) is or was a director or officer of another corporation (i) at a time when the other corporation is or was an affiliate of the corporation, or (ii) at the request of the corporation, or (c) at the request of the corporation, 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.

An “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 corporation or an associated corporation (a) is or may be joined as a party, or (b) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding.

A corporation must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by the eligible party in respect of that proceeding if the eligible party (a) has not been reimbursed for those expenses, and (b) is wholly successful, on the merits or otherwise, in the outcome of the proceeding or is substantially successful on the merits in the outcome of the proceeding.

A corporation 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 the corporation first receives from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited, the eligible party will repay the amounts advanced.

Notwithstanding any of the foregoing, a corporation must not indemnify an eligible party or pay the expenses of an eligible party if any of the following circumstances apply:

If an eligible proceeding is brought against an eligible party by or on behalf of the corporation or by or on behalf of an associated corporation, the corporation must not (a) indemnify the eligible party in respect of the proceeding or (b) pay the expenses of the eligible party in respect of the proceeding.

A corporation may purchase and maintain insurance for the benefit of an eligible party or the heirs and personal or other legal representatives of the eligible party against any liability that may be incurred 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 corporation or an associated corporation.

Articles

Our Articles provide that, subject to the Business Corporations Act (British Columbia), the Company must indemnify an eligible party and their respective heirs and personal or other legal representatives against all eligible penalties to which such eligible party is or may be liable. The Company 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 eligible party is deemed to have contracted with the Company on this term. The Articles also provide that the Company may indemnify any person, subject to any restrictions in the Business Corporations Act (British Columbia).

Our Articles defines the following terms: (1) an “eligible penalty” means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, an “eligible proceeding”; (2) an “eligible party” means a director, former director or alternate director of the Company; (3) an “eligible proceeding” means a legal proceeding or investigative action (whether current, threatened, pending or completed), 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 alternate director of the Company (a) is or may be joined as a party, or (b) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding; and (4) “expenses” has the meaning set out in the Business Corporations Act (British Columbia).

Our Articles provide that the Company may purchase and maintain insurance for the benefit of any person (or his or her heirs or legal personal representatives) who is or was a director, alternative director, officer, employee or agent, or held or holds such position or a position equivalent to the foregoing (each, an “insured party”) with respect to (i) the Company; (ii) a corporation at a time when the corporation was an affiliate of the Company; (iii) at the request of the Company, served in such capacity with respect to a corporation, partnership, trust, joint venture or other unincorporated entity, against any liability that may be incurred by him or her acting in such capacity.

We maintain liability insurance policies regarding our directors and officers against certain liabilities that they may incur in such capacities.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the 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 8. Exhibits.

Item 9. Undertakings.

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 Registration Fee” table 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 (i) and (ii) above do 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 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 herein, 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.

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 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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 Securities and Exchange 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.
