with the Securities and Exchange Commission are incorporated herein by
reference:

               (a) The Company's latest annual report filed pursuant to Section

          Act") or the latest prospectus filed pursuant to Rule 424(b) under the
          Securities Act of 1933 (the "Securities Act") that contains audited

          such statements have been filed.

               (b) All other reports filed pursuant to Section 13(a) or 15(d) of

Item 6.   Indemnification of Directors and Officers.
          ------------------------------------------

          Article VI (the "Article") of the Articles of Incorporation of the
Registrant requires the Registrant to indemnify directors and officers to the
fullest extent not prohibited by law. The right to and amount of indemnification
will be ultimately subject to determination by a court that indemnification in
the circumstances presented is consistent with public policy and other
provisions of law. It is likely, however, that the Article would require
indemnification at least to the extent that indemnification is authorized by the
Oregon Business Corporation Act (the "Act"). The effect of the Act is summarized
as follows:

               (a) The Act permits a corporation to grant a right of
          indemnification in respect of any pending, threatened or completed
          action, suit or proceeding ("proceeding"), other than an action by or
          in the right of the corporation, against expenses (including
          attorneys' fees), judgments, penalties, fines and amounts paid in
          settlement actually and reasonably incurred, provided the person
          concerned acted in good faith and in a manner the person reasonably
          believed to be in or at least not opposed to the best interests of the
          corporation and, with respect to any criminal action or proceeding,
          had no reasonable cause to believe his or her conduct was unlawful.
          Indemnification is not permitted in connection with a proceeding in
          which a person is adjudged liable on the basis that personal benefit
          was improperly received unless indemnification is permitted by a court
          upon a finding that the person is fairly and reasonably entitled to
          indemnification in view of all of the relevant circumstances. The
          termination of a proceeding by judgment, order, settlement, conviction
          or upon a plea of nolo contendere or its equivalent is not, of itself,
          determinative that the person did not meet the prescribed standard of
          conduct.

               (b) The Act permits a corporation to grant a right of
          indemnification in respect of any proceeding by or in the right of the
          corporation against the reasonable expenses (including attorneys'
          fees) incurred if the person concerned acted in good faith and in a
          manner the person reasonably believed to be in or at least not opposed
          to the best interests of the corporation, except that no
          indemnification may be granted if such person is adjudged to be liable
          to the corporation unless permitted by a court.

               (c) The corporation may not indemnify a person in respect of a
          proceeding described in (a) or (b) above unless it is determined in
          the specific case that indemnification is permissible because the
          person has met the prescribed standard of conduct by any one of the
          following: (i) the Board of Directors, by a majority vote of a quorum
          consisting of directors not at the time parties to the proceeding,
          (ii) if a quorum of directors not party to the proceeding cannot be
          obtained, by a majority vote of a committee of two or more directors
          not at the time parties to the proceeding, (iii) by special legal
          counsel selected by the Board of Directors or such committee thereof,
          as described in (i) and (ii) above, or (iv) by the shareholders.

                                      II-2
<PAGE>
          Indemnification can also be ordered by a court if the court determines
          that indemnification is fair in view of all of the relevant
          circumstances. Notwithstanding the foregoing, every person who has
          been wholly successful, on the merits or otherwise, in defense of a
          proceeding described in (a) or (b) is entitled to be indemnified as a
          matter of right against reasonable expenses incurred in connection
          with the proceeding.

               (d) The corporation may pay for or reimburse the reasonable
          expenses incurred in defending a proceeding in advance of the final
          disposition thereof if the director or officer receiving the advance
          furnishes (i) a written affirmation of his or her good faith belief
          that he or she has met the prescribed standard of conduct, and (ii) a
          written undertaking to repay the advance in the event indemnification
          is not authorized.

          The Registrant has entered into indemnification agreements with each
of the Registrant's executive officers and directors. In general, these
indemnification agreements require the Registrant to indemnify such persons
against certain liabilities, expenses, judgments, fines, settlements and other
amounts actually and reasonably incurred (including expenses of a derivative
action) in connection with any proceeding, whether actual or threatened, to
which any such person may be made a party by reason of the fact that such person
is or was a director and/or an officer of the Registrant or any of its
affiliated enterprises. Such indemnification agreements also set forth certain
procedures, including the advancement of expenses, that apply in the event of a
claim for indemnification.

          The rights of indemnification described above are not exclusive of any
other rights of indemnification to which officers or directors may be entitled
under any statute, agreement, vote of shareholders, action of directors, or
otherwise.

          The Registrant has directors' and officers' liability insurance
coverage that insures directors and officers of the Registrant and its
subsidiaries against certain liabilities.

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. Notwithstanding the foregoing, any
                    increase or decrease in volume of securities offered (if the
                    total dollar value of the 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%
                    change in the maximum aggregate offering price set forth in
                    the "Calculation of Registration Fee" table in the effective
                    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 with or furnished to the
Commission by the registrant

                                      II-4
<PAGE>
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
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 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
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 Act and will
be governed by the final adjudication of such issue.

               (a) The Company's latest annual report filed pursuant to Section

Item 5.   Interests of Named Experts and Counsel.
          ---------------------------------------

          Not Applicable.

                                      II-1
Item 6.   Indemnification of Directors and Officers.
          ------------------------------------------

          Article VI (the "Article") of the Articles of Incorporation of the
Registrant requires the Registrant to indemnify directors and officers to the
fullest extent not prohibited by law. The right to and amount of indemnification
will be ultimately subject to determination by a court that indemnification in
the circumstances presented is consistent with public policy and other
provisions of law. It is likely, however, that the Article would require
indemnification at least to the extent that indemnification is authorized by the
Oregon Business Corporation Act (the "Act"). The effect of the Act is summarized
as follows:

               (a) The Act permits a corporation to grant a right of
          indemnification in respect of any pending, threatened or completed
          action, suit or proceeding ("proceeding"), other than an action by or
          in the right of the corporation, against expenses (including
          attorneys' fees), judgments, penalties, fines and amounts paid in
          settlement actually and reasonably incurred, provided the person
          concerned acted in good faith and in a manner the person reasonably
          believed to be in or at least not opposed to the best interests of the
          corporation and, with respect to any criminal action or proceeding,
          had no reasonable cause to believe his or her conduct was unlawful.
          Indemnification is not permitted in connection with a proceeding in
          which a person is adjudged liable on the basis that personal benefit
          was improperly received unless indemnification is permitted by a court
          upon a finding that the person is fairly and reasonably entitled to
          indemnification in view of all of the relevant circumstances. The
          termination of a proceeding by judgment, order, settlement, conviction
          or upon a plea of nolo contendere or its equivalent is not, of itself,
          determinative that the person did not meet the prescribed standard of
          conduct.

               (b) The Act permits a corporation to grant a right of
          indemnification in respect of any proceeding by or in the right of the
          corporation against the reasonable expenses (including attorneys'
          fees) incurred if the person concerned acted in good faith and in a
          manner the person reasonably believed to be in or at least not opposed
          to the best interests of the corporation, except that no
          indemnification may be granted if such person is adjudged to be liable
          to the corporation unless permitted by a court.

               (c) The corporation may not indemnify a person in respect of a
          proceeding described in (a) or (b) above unless it is determined in
          the specific case that indemnification is permissible because the
          person has met the prescribed standard of conduct by any one of the
          following: (i) the Board of Directors, by a majority vote of a quorum
          consisting of directors not at the time parties to the proceeding,
          (ii) if a quorum of directors not party to the proceeding cannot be
          obtained, by a majority vote of a committee of two or more directors
          not at the time parties to the proceeding, (iii) by special legal
          counsel selected by the Board of Directors or such committee thereof,
          as described in (i) and (ii) above, or (iv) by the shareholders.

                                      II-2
Indemnification can also be ordered by a court if the court determines
          that indemnification is fair in view of all of the relevant
          circumstances. Notwithstanding the foregoing, every person who has
          been wholly successful, on the merits or otherwise, in defense of a
          proceeding described in (a) or (b) is entitled to be indemnified as a
          matter of right against reasonable expenses incurred in connection
          with the proceeding.

               (d) The corporation may pay for or reimburse the reasonable
          expenses incurred in defending a proceeding in advance of the final
          disposition thereof if the director or officer receiving the advance
          furnishes (i) a written affirmation of his or her good faith belief
          that he or she has met the prescribed standard of conduct, and (ii) a
          written undertaking to repay the advance in the event indemnification
          is not authorized.

          The Registrant has entered into indemnification agreements with each
of the Registrant's executive officers and directors. In general, these
indemnification agreements require the Registrant to indemnify such persons
against certain liabilities, expenses, judgments, fines, settlements and other
amounts actually and reasonably incurred (including expenses of a derivative
action) in connection with any proceeding, whether actual or threatened, to
which any such person may be made a party by reason of the fact that such person
is or was a director and/or an officer of the Registrant or any of its
affiliated enterprises. Such indemnification agreements also set forth certain
procedures, including the advancement of expenses, that apply in the event of a
claim for indemnification.

          The rights of indemnification described above are not exclusive of any
other rights of indemnification to which officers or directors may be entitled
under any statute, agreement, vote of shareholders, action of directors, or
otherwise.

          The Registrant has directors' and officers' liability insurance
coverage that insures directors and officers of the Registrant and its
subsidiaries against certain liabilities.

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. Notwithstanding the foregoing, any
                    increase or decrease in volume of securities offered (if the
                    total dollar value of the 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%
                    change in the maximum aggregate offering price set forth in
                    the "Calculation of Registration Fee" table in the effective
                    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 with or furnished to the
Commission by the registrant

                                      II-4
pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
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 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
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 Act and will
be governed by the final adjudication of such issue.
