     Sections 23B.08.500 through 23.B.08.600 of the Washington Business
     Corporation Act (the &quot;WBCA&quot;) authorize a court to award, or a
     corporation's board of directors to grant, indemnification to directors and
     officers on terms sufficiently broad to permit indemnification under
     certain circumstances for liabilities arising under the Securities Act of
     1933, as amended (the &quot;Securities Act&quot;).&nbsp; Section 23B.08.320
     of the WBCA authorizes a corporation to limit a director's liability to the
     corporation or its shareholders for monetary damages for acts or omissions
     as a director, except in certain circumstances involving intentional
     misconduct, knowing violations of law or illegal corporate loans or
     distributions, or any transaction from which the director personally
     receives a benefit in money, property or services to which the director is
     not legally entitled.</font></p>
     <p><font face="Times New Roman" size="2">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
     The Company's Second Amended and Restated Articles of Incorporation and
     Amended and Restated Bylaws contain provisions permitting the Company to
     indemnify its directors and officers to the full extent permitted by
     Washington law.&nbsp; In addition, the Company's Second Amended and
     Restated Articles of Incorporation contain a provision implementing, to the
     fullest extent permitted by Washington law, the above limitations on a
     director's liability to the Company and its shareholders. The Company has
     entered into certain indemnification agreements with its directors and
     certain of its officers, the form of which is attached as Exhibit 10.1 to
     its Registration Statement on Form S-1 (File No. 333-75817).&nbsp; The
     indemnification agreements provide the Company's directors and certain of
     its officers with indemnification to the maximum extent permitted by the
     WBCA.&nbsp; The directors and officers of the Company also may be
     indemnified against liability they may incur for serving in that capacity
     pursuant to a liability insurance policy maintained by the Company for this
     purpose.</font></p>

     The undersigned Registrant hereby undertakes that, for purposes of

     the Registrant's annual report pursuant to Section 13(a) or
     Section&nbsp;15(d) of the Securities Exchange Act of 1934 that is

     Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 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 of 1933 and is, therefore,
     unenforceable.&nbsp; 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 of 1933 and will be governed by the final adjudication of
     such issue.</font></p>

Item 6.  Indemnification
     of Directors and Officers.
Sections 23B.08.500 through 23.B.08.600 of the Washington Business
     Corporation Act (the "WBCA") authorize a court to award, or a
     corporation's board of directors to grant, indemnification to directors and
     officers on terms sufficiently broad to permit indemnification under
     certain circumstances for liabilities arising under the Securities Act of
     1933, as amended (the "Securities Act").  Section 23B.08.320
     of the WBCA authorizes a corporation to limit a director's liability to the
     corporation or its shareholders for monetary damages for acts or omissions
     as a director, except in certain circumstances involving intentional
     misconduct, knowing violations of law or illegal corporate loans or
     distributions, or any transaction from which the director personally
     receives a benefit in money, property or services to which the director is
     not legally entitled.
The Company's Second Amended and Restated Articles of Incorporation and
     Amended and Restated Bylaws contain provisions permitting the Company to
     indemnify its directors and officers to the full extent permitted by
     Washington law.  In addition, the Company's Second Amended and
     Restated Articles of Incorporation contain a provision implementing, to the
     fullest extent permitted by Washington law, the above limitations on a
     director's liability to the Company and its shareholders. The Company has
     entered into certain indemnification agreements with its directors and
     certain of its officers, the form of which is attached as Exhibit 10.1 to
     its Registration Statement on Form S-1 (File No. 333-75817).  The
     indemnification agreements provide the Company's directors and certain of
     its officers with indemnification to the maximum extent permitted by the
     WBCA.  The directors and officers of the Company also may be
     indemnified against liability they may incur for serving in that capacity
     pursuant to a liability insurance policy maintained by the Company for this
     purpose.

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 of 1933;
(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;
3
(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 by the Registrant pursuant to
     Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in this Registration Statement.
(2)               
     That, for the purpose of determining any liability under the Securities Act
     of 1933, 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 of 1933, each filing of
     the Registrant's annual report pursuant to Section 13(a) or
     Section 15(d) of the Securities Exchange Act of 1934 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
     of 1933 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 of 1933 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 of 1933 and will be governed by the final adjudication of
     such issue.
