ITEM 4.   DESCRIPTION OF SECURITIES.

ITEM 5.   INTERESTS OF NAMED EXPERTS AND COUNSEL.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Washington Business Corporation Act includes a provision (Section 23B.08.320
of the Revised Code of Washington) that permits a corporation to limit a
director's liability to the corporation or its shareholders for monetary damages
for his acts or omissions as a director, except for those acts or omissions
involving intentional misconduct or a knowing violation of law, certain unlawful
distributions or a transaction whereby the director received a personal benefit
to which he was not legally entitled.  The Company's Restated Articles of
Incorporation includes a provision implementing the allowed limitations on a
director's liability to the Company or its shareholders.

The Washington Business Corporation Act (Sections 23B.08.500 through 23B.08.600
of the Revised Code of Washington) authorizes a court to award, or a
corporation's Board of Directors to grant, indemnity to directors and officers
in terms sufficiently broad to permit such indemnification under certain
circumstances for liabilities arising under the Securities Act of 1933, as
amended.  Pursuant to its Amended & Restated Bylaws, the Company will indemnify
its officers, directors and other persons described in Section 23B.08.510 of the
Washington Business Corporation Act to the full extent permitted by law.  The
Company maintains insurance for this purpose.  Such insurance generally insures
the directors and officers against claims due to any breach of duty, neglect,
error, misstatement, misleading statement, omission or other act solely by
reason of their being directors and officers, and for acts, errors and omissions
by them in the provision of professional services to the Company.

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;

               (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 registration statement is on Form S-3, Form S-8 or Form F-3, and 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 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by 


                                     II-2

 
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.

     (e)  The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulations S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (h)  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 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 Act and will
be governed by the final adjudication of such issue.
