On behalf of Natural Gas Systems, Inc., a Nevada corporation, the undersigned

      Natural Gas Systems, Inc. hereby acknowledges that:

      1. Should the Commission or the staff, acting pursuant to delegated

      3. Natural Gas Systems, Inc. may not assert the declaration of
effectiveness as a defense in any proceeding initiated by the Commission or any
