director or officer who is wholly successful in his defense of a proceeding to which he is a party because of his status as such, unless limited by the articles of incorporation, and (ii)&nbsp;a corporation may indemnify a director or officer if he
is not wholly successful in such defense, if it is determined as provided in the statute that the director meets a certain standard of conduct, provided that when a director is liable to the corporation, the corporation may not indemnify him. The
statute also permits a director or officer of a corporation who is a party to a proceeding to apply to the courts for indemnification or advance of expenses, unless the articles of incorporation provide otherwise, and the court may order
indemnification or advancement of expenses under certain circumstances set forth in the statute. The statute further provides that a corporation may in its articles of incorporation or bylaws or by resolution provide indemnification in addition to
that provided by statute, subject to certain conditions set forth in the statute. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The articles of incorporation of the Company provide,
among other things, for the indemnification of directors (including directors of subsidiaries), and authorize the board of directors to pay reasonable expense incurred by, or to satisfy a judgment or fine against, a current or former director in
connection with any personal legal liability incurred by the individual while acting for the Company within the scope of his employment, and which was not the result of conduct finally adjudged to be &#147;egregious&#148; conduct.
&#147;Egregious&#148; conduct is defined as intentional misconduct, a knowing violation of law, or participation in any transaction from which the person will personally receive a benefit in money, property or services to which that person is not
legally entitled. The articles of incorporation also include a provision that limits the liability of directors of the Company from any personal liability to the Company or its shareholders for conduct not found to have been egregious. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company has entered into Indemnification Agreements with each of its directors. The Indemnification Agreements codify procedural
mechanisms pursuant to which directors may enforce the indemnification rights that such directors are granted under the Company&#146;s articles of incorporation and the WBCA. </P>

Item 6.
Indemnification of Directors and Officers.
Sections 23B.08.500 through 23B.08.600 of
the Washington Business Corporation Act ("WBCA") contain specific provisions relating to indemnification of directors and officers of Washington corporations. In general, the statute provides that (i) a corporation must indemnify a
director or officer who is wholly successful in his defense of a proceeding to which he is a party because of his status as such, unless limited by the articles of incorporation, and (ii) a corporation may indemnify a director or officer if he
is not wholly successful in such defense, if it is determined as provided in the statute that the director meets a certain standard of conduct, provided that when a director is liable to the corporation, the corporation may not indemnify him. The
statute also permits a director or officer of a corporation who is a party to a proceeding to apply to the courts for indemnification or advance of expenses, unless the articles of incorporation provide otherwise, and the court may order
indemnification or advancement of expenses under certain circumstances set forth in the statute. The statute further provides that a corporation may in its articles of incorporation or bylaws or by resolution provide indemnification in addition to
that provided by statute, subject to certain conditions set forth in the statute.
The articles of incorporation of the Company provide,
among other things, for the indemnification of directors (including directors of subsidiaries), and authorize the board of directors to pay reasonable expense incurred by, or to satisfy a judgment or fine against, a current or former director in
connection with any personal legal liability incurred by the individual while acting for the Company within the scope of his employment, and which was not the result of conduct finally adjudged to be "egregious" conduct.
"Egregious" conduct is defined as intentional misconduct, a knowing violation of law, or participation in any transaction from which the person will personally receive a benefit in money, property or services to which that person is not
legally entitled. The articles of incorporation also include a provision that limits the liability of directors of the Company from any personal liability to the Company or its shareholders for conduct not found to have been egregious.
The Company has entered into Indemnification Agreements with each of its directors. The Indemnification Agreements codify procedural
mechanisms pursuant to which directors may enforce the indemnification rights that such directors are granted under the Company's articles of incorporation and the WBCA.

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 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the
effective Registration Statement;
4
(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 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 Securities 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 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 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 of 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 Act and will be governed by the final
adjudication of such issue.
