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:

                       (A) To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                       (B) 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 and 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 20% change in the
                           maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement; and

                       (C) 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;

<PAGE>
 
                       provided, however, that paragraphs (a)(1)(A) and
                       (a)(1)(B) 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 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 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.

             (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 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 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:

                       (A) To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                       (B) 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 and 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 20% change in the
                           maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement; and

                       (C) 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
provided, however, that paragraphs (a)(1)(A) and
                       (a)(1)(B) 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 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 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.

             (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 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 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.
