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)

                                      II-3


                          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 this Registration Statement;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above
               shall 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 Securities and
               Exchange Commission 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 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
               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 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
               the Act and will be governed by the final adjudication of such
               issue.

                                      II-4
