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

         (2)      The undersigned Registrant agrees that every prospectus that
