ITEM 17. UNDERTAKINGS

         (1)      The undersigned Registrant agrees that prior to any public
                  reoffering of the securities registered through use of a
                  prospectus which is part of this Registration Statement by any
                  person or party who is deemed to be an underwriter within the
                  meaning of Rule 145(c) of the Securities Act of 1933, as
                  amended, the reoffering prospectus will contain information
                  called for by the applicable registration form for reofferings
                  by persons who may be deemed underwriters, in addition to the
                  information called for by other items of the applicable form.

         (2)      The undersigned Registrant agrees that every prospectus that
                  is filed under paragraph (1) above will be filed as part of an
                  amendment to the registration statement and will not be used
                  until the amendment is effective, and that, in determining any
                  liability under the Securities Act of 1933, as amended, each
                  post-effective amendment shall be deemed to be a new
                  registration statement for the securities offered therein, and
                  the offering of securities at that time shall be deemed to be
                  the initial bona fide offering of them.
