fines and amounts paid in settlement, reasonably incurred in connection with the
defense or settlement of any threatened, pending or completed legal proceeding
in which any such person is involved by reason of the fact that such person is

faith and in a manner he or she reasonably believed to be in or not opposed to

ITEM 9.        UNDERTAKINGS

               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;

                                      II-2
<PAGE>   5

provided however, that clauses (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 clauses is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 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 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.

               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 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 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.

               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 whether such
indemnification by it is against public policy as expressed in such Act and will
be governed by the final adjudication of such issue.

faith and in a manner he or she reasonably believed to be in or not opposed to

ITEM 9.        UNDERTAKINGS

               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;

                                      II-2
5

provided however, that clauses (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 clauses is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 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 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.

               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 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 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.

               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 whether such
indemnification by it is against public policy as expressed in such Act and will
be governed by the final adjudication of such issue.
