ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

     The following documents are incorporated by reference in the Registration
Statement:

     (a) The Registrant's annual report on Form 10-KSB.

     (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).

     (c) The description of the Common Stock contained in the Registrant's
Registration Statement on Form 10-SB, including any amendments or reports filed
for the purpose of updating such description.

     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 indicates that all securities offered hereby
have been sold or which deregisters all securities covered hereby then remaining
unsold, shall also be deemed to be incorporated by reference in 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.

     The Registrant's Articles of Incorporation provide that the Registrant must
indemnify each of its (i) fiduciaries within the meaning of the Employee
Retirement Income Security Act of 1974, as amended, with respect to any employee
benefit plan, and (ii) directors and officers, to the fullest extent permitted
under the Oregon Business Corporation Act, against all liabilities incurred by
reason of the fact that the person is or was a director or officer of the
Registrant or a fiduciary of an employee benefit plan, or is or was serving at
the request of the Registrant as a director or officer, or fiduciary of an
employee benefit plan, of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise.

     The effect of these provisions is potentially to indemnify the Registrant's
directors and officers from all costs and expenses of liability incurred by them
in connection with any action, suit or proceeding in which they are involved by
reason of their affiliation with the Registrant.

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;

         (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 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.
<PAGE>
 
     (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 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 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 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.
