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) 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 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 percent 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;

          (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.

          (4)  If the registrant is a foreign private issuer, to file a post-
          effective amendment to the registration statement to include any
          financial statements required by Rule 3-19 of this chapter at the
          start of any delayed offering or throughout a continuous offering.
          Financial statements and information otherwise required by Section
          10(a)(3) of the Act need not be furnished, provided, that the
          registrant includes in the prospectus, by means of a post-effective
          amendment, financial statements required pursuant to this paragraph
          (a)(4) and other information necessary to ensure that all other
          information in the prospectus is at least as current as the date of
          those financial statements.  Notwithstanding the foregoing, with
          respect to registration statements on Form F-3, a post-effective
          amendment need not be filed to include financial statements and
          information required by Section 10(a)(3) of the Act or Rule 3-19 of
          this chapter if such financial statements and information are
          contained in periodic reports filed with or furnished to the
          Commission by the registrant pursuant to section 13 or section 15(d)
          of the Securities Exchange Act of 1934 that are incorporated by
          reference in the Form F-3.

                                       4
<PAGE>
 
     (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 (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.


     (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.

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) 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 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 percent 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;

          (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.

          (4)  If the registrant is a foreign private issuer, to file a post-
          effective amendment to the registration statement to include any
          financial statements required by Rule 3-19 of this chapter at the
          start of any delayed offering or throughout a continuous offering.
          Financial statements and information otherwise required by Section
          10(a)(3) of the Act need not be furnished, provided, that the
          registrant includes in the prospectus, by means of a post-effective
          amendment, financial statements required pursuant to this paragraph
          (a)(4) and other information necessary to ensure that all other
          information in the prospectus is at least as current as the date of
          those financial statements.  Notwithstanding the foregoing, with
          respect to registration statements on Form F-3, a post-effective
          amendment need not be filed to include financial statements and
          information required by Section 10(a)(3) of the Act or Rule 3-19 of
          this chapter if such financial statements and information are
          contained in periodic reports filed with or furnished to the
          Commission by the registrant pursuant to section 13 or section 15(d)
          of the Securities Exchange Act of 1934 that are incorporated by
          reference in the Form F-3.

                                       4
(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 (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.

     (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.

                                       5
