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
               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 purposes 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 the 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
          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 a
          successful defense of any action, suit or proceeding) is asserted by
          such director, officer or controlling person in connection with the
          securities being registered hereunder, the Registrant will, unless in
          the opinion of its counsel the question has already been settled by
          controlling precedent, submit to a court of appropriate jurisdiction
          the question of whether such indemnification by it is against public
          policy as expressed in the Securities 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
               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 purposes 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 the 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
          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 a
          successful defense of any action, suit or proceeding) is asserted by
          such director, officer or controlling person in connection with the
          securities being registered hereunder, the Registrant will, unless in
          the opinion of its counsel the question has already been settled by
          controlling precedent, submit to a court of appropriate jurisdiction
          the question of whether such indemnification by it is against public
          policy as expressed in the Securities Act and will be governed by the
          final adjudication of such issue.
