  at the request of the Registrant as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. The Registrant may, to the full extent permitted by law, purchase and maintain insurance on behalf of any such
  person against any liability which may be asserted against such person. To the full extent permitted by law, the indemnification provided in the Articles does include expenses (including attorneys&#146; fees), judgments, fines and amounts paid in
  settlement, and, in the manner provided by law, any such expenses may be paid by the Registrant in advance of the final disposition of such action, suit or proceeding. The indemnification provided in the Articles also is not deemed to limit the
  right of the Registrant to indemnify any other person for any such expenses to the full extent permitted by law, and is not deemed exclusive of any other rights to which any person seeking indemnification from the Registrant may be entitled under

  violating Section 23B.08.310 of the Washington Corporation Act, or for any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled. Specifically,
  Section 23B.08.560 of the Washington Corporation Act provides that if authorized by (i) the articles of incorporation, (ii) a bylaw adopted or ratified by the shareholders, or (iii) a resolution adopted or ratified, before or
  after the event, by the shareholders, a company will have the power to indemnify a director made party to a proceeding, or to obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations on
  indemnification contained in Section 23B.08.510 through 23B.08.550 of the Washington Corporation Act, provided that no such indemnity shall indemnify any director (i) for acts or omissions that involve intentional misconduct by the
  director or a knowing violation of the law by the director, (ii) for conduct finally adjudged to be in violation of
  Section 23B.08.310 of the Washington Corporation Act, or (iii) for any transaction from which the director will
  personally receive a benefit in money, property or services to which the director is not legally entitled.
  Furthermore,
  Section 23B.08580 of the Washington Corporation Act provides that a company may purchase and maintain insurance on behalf of an individual who is or was a director, officer, employee or agent of such company, or who, while a director, officer,
  employee, or agent of such company, is or was serving at the request of such company as a director, officer, partner, trustee, employee, or agent of another foreign or domestic company, partnership, joint venture, trust, employee benefit plan, or
  other enterprise, against liability asserted against or incurred by such individual in that capacity or arising from such individual's status as a director, officer, employee, or agent, whether or not such company would have power to indemnify
  such individual against the same liability under Section 23B.08.510 or 23B.08.520 of the Washington Corporation Act.
  Section 7.1 of the Articles of Incorporation of the Registrant, referred to as the "Articles", provides that
  the Registrant may indemnify, in the manner and to the full extent permitted by law, any person (or the estate of any person) who was or is a party to, or is threatened to be made a party to any threatened, pending or complete action, suit or
  proceeding, whether or not by or in the right of the Registrant, and whether civil, criminal, administrative, investigative or otherwise, by reason of the fact that such person is or was a director or officer of the Registrant, or is or was serving
  at the request of the Registrant as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. The Registrant may, to the full extent permitted by law, purchase and maintain insurance on behalf of any such
  person against any liability which may be asserted against such person. To the full extent permitted by law, the indemnification provided in the Articles does include expenses (including attorneys' fees), judgments, fines and amounts paid in
  settlement, and, in the manner provided by law, any such expenses may be paid by the Registrant in advance of the final disposition of such action, suit or proceeding. The indemnification provided in the Articles also is not deemed to limit the
  right of the Registrant to indemnify any other person for any such expenses to the full extent permitted by law, and is not deemed exclusive of any other rights to which any person seeking indemnification from the Registrant may be entitled under
  any agreement, vote of shareholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office.
  Section 7.2 of the Articles provides that no director of the Registrant shall be personally liable to the Registrant or
  its shareholders for monetary damages for his conduct as a director, except for (i) acts or omissions that involve intentional misconduct or a knowing violation of law by the director, (ii) approval of distributions or loans in violation
  of Section 23B.08.310 of the Washington Corporation Act, or (iii) any transaction from which the director will personally receive a benefit in money, property or services to which the director is not legally entitled.
  According to Section 7.2 of the Articles, if the Washington Corporation Act is hereafter amended to authorize corporate
  action further eliminating or limiting the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the fullest extent permitted by the Washington Corporation Act, as so amended.
  Furthermore, Section 7.2 specifies that any amendment to or repeal of Article 7 of the Articles shall
  not adversely affect any right or protection of a director of the Registrant for or with respect to any acts or omissions of such director occurring prior to such amendment or repeal.
  The Registrant has entered into indemnity agreements, referred to as the "Indemnity Agreements", with each of its
  directors and certain of its executive officers. The Registrant has agreed under each of the Indemnity Agreements to indemnify each of its directors and such officers against any and all claims and costs that are or may be brought against him as a
  result of his being one of the Registrant's directors, officers or employees or that of a company related to the Registrant. However, under the Indemnity Agreements, the Registrant is not obligated to indemnify a director or officer against any
  claims or costs in certain instances, including if it is determined that the director or officer failed to act honestly and in good faith with a view to the Registrant's best interests, if the director or officer failed to disclose an interest
  or conflict as required under corporate legislation in Washington state or the Registrant is not permitted to indemnify the director or officer under such legislation, or if the director or officer has violated any insider trading rules under United
  States federal and state securities laws.

  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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20%
  change in 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 periodic reports filed with or furnished to the SEC 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)
  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 offering 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 provisions described in Item 6 above, or otherwise, the Registrant has been advised that in the opinion of the SEC 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 of 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.
  SIGNATURES
  Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe
  that it meets all of the 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 Vancouver,
