                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

        The following documents filed with the Securities and Exchange
Commission (the "Commission") are hereby incorporated by reference in this
Registration Statement:

               (a) The Registrant's Annual Report on Form 10-K for the year
ended December 31, 1997, filed on March 13, 1998, which contains audited
financial statements for the most recent fiscal year for which such statements
have been filed;

               (b) All other reports filed by the Registrant pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), since the end of the fiscal year covered by the Annual Report on Form
10-K referred to in (a) above; and

               (c) The description of the Registrant's Common Stock contained in
the Registration Statement on Form 8-A filed on April 27, 1990 under Section
12(g) of the Exchange Act.

        All documents filed by the Registrant pursuant to Sections 13(a), 13(c),
14 and 15(d) of the Exchange Act after the date hereof and prior to the filing
of a post-effective amendment, which indicate that the securities offered hereby
have been sold or which deregister the securities covered hereby then remaining
unsold, shall also be deemed to be incorporated by reference into this
Registration Statement and to be a part hereof commencing on the respective
dates on which such documents are filed.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act 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 10 of the Registrant's Restated Bylaws provides for
indemnification of the Registrant's directors, officers, employees and agents to
the maximum extent permitted by Washington law.

        Section 23B.08.320 of the Washington Business Corporation Act 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, self-dealing or illegal
corporate loans or distributions, or any transactions from which the director
personally receives a benefit in money, property or services to which the
director is not entitled. Article 7 of the Registrant's Restated Articles of
Incorporation contains provisions implementing, to the fullest extent permitted
by Washington law, such limitations on a director's liability to the Registrant
and its shareholders.

        Officers and directors of the Registrant are covered by insurance (with
certain exceptions and certain limitations) that indemnifies them against losses
and liabilities arising from certain alleged "wrongful acts," including alleged
errors or misstatements, or certain other alleged wrongful acts or omissions
constituting neglect or breach of duty.

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 this 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 this Registration
Statement; and

               (iii) To include any material information with respect to the
plan of distribution not previously disclosed in this Registration Statement or
any material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(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 by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this 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 benefits plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this 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.


                                      II-2

<PAGE>   4



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 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.

                 INFORMATION REQUIRED IN REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

        The following documents filed with the Securities and Exchange
Commission (the "Commission") are hereby incorporated by reference in this
Registration Statement:

               (a) The Registrant's Annual Report on Form 10-K for the year
ended December 31, 1997, filed on March 13, 1998, which contains audited
financial statements for the most recent fiscal year for which such statements
have been filed;

               (b) All other reports filed by the Registrant pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), since the end of the fiscal year covered by the Annual Report on Form
10-K referred to in (a) above; and

               (c) The description of the Registrant's Common Stock contained in
the Registration Statement on Form 8-A filed on April 27, 1990 under Section
12(g) of the Exchange Act.

        All documents filed by the Registrant pursuant to Sections 13(a), 13(c),
14 and 15(d) of the Exchange Act after the date hereof and prior to the filing
of a post-effective amendment, which indicate that the securities offered hereby
have been sold or which deregister the securities covered hereby then remaining
unsold, shall also be deemed to be incorporated by reference into this
Registration Statement and to be a part hereof commencing on the respective
dates on which such documents are filed.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

        Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act 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 10 of the Registrant's Restated Bylaws provides for
indemnification of the Registrant's directors, officers, employees and agents to
the maximum extent permitted by Washington law.

        Section 23B.08.320 of the Washington Business Corporation Act 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, self-dealing or illegal
corporate loans or distributions, or any transactions from which the director
personally receives a benefit in money, property or services to which the
director is not entitled. Article 7 of the Registrant's Restated Articles of
Incorporation contains provisions implementing, to the fullest extent permitted
by Washington law, such limitations on a director's liability to the Registrant
and its shareholders.

        Officers and directors of the Registrant are covered by insurance (with
certain exceptions and certain limitations) that indemnifies them against losses
and liabilities arising from certain alleged "wrongful acts," including alleged
errors or misstatements, or certain other alleged wrongful acts or omissions
constituting neglect or breach of duty.

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 this 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 this Registration
Statement; and

               (iii) To include any material information with respect to the
plan of distribution not previously disclosed in this Registration Statement or
any material change to such information in this Registration Statement;

provided, however, that paragraphs (1)(i) and (1)(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 by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in this 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 benefits plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this 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.

                                      II-2

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 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.
