ITEM 9. UNDERTAKINGS.

         (a)      The Registrant hereby undertakes:

                  (i)      To file, during any period 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.

                  (ii)     That, for the purpose of determining any liability
                           under the Securities Act, each 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.

                  (iii)    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 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 (and, where
                  applicable, each filing of an employee benefit plan's annual
                  report pursuant to 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 indemnification for liabilities arising under the
                  Securities Act may be permitted to directors, officers and
                  controlling persons of the Registrant pursuant to law, the
                  Registrant's Amended and Restated Certificate of
                  Incorporation, Bylaws or indemnification agreements, 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 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
                  matter has 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 Registrant hereby undertakes:

                  (i)      To file, during any period 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

                           in the registration statement.

                  (ii)     That, for the purpose of determining any liability
                           under the Securities Act, each 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.

                  (iii)    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 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 (and, where
                  applicable, each filing of an employee benefit plan's annual
                  report pursuant to 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 indemnification for liabilities arising under the
                  Securities Act may be permitted to directors, officers and
                  controlling persons of the Registrant pursuant to law, the
                  Registrant's Amended and Restated Certificate of
                  Incorporation, Bylaws or indemnification agreements, 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 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
                  matter has 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.
