      Capitalized terms used and not otherwise defined in this Addendum have the

            (iii) Build-out Plan Map.

      2. Governing Law and Jurisdiction. (a) Section 17.12 of the Management
Agreement, Section 9.11 of the Services Agreement and Section 15.8 of each of
the Trademark License Agreements is deleted in its entirety and replaced with
the following language:

            Governing Law. The internal laws of the State of Kansas (without
      regard to principles of conflicts of law) govern the validity of this
      agreement, the construction of its terms, and the interpretation of the
      rights and duties of the parties.

      (b) Paragraphs (a) and (b) of Section 15.13 of each of the Trademark
License Agreements are deleted in their entirety and replaced with the following
language:

            (a) Each party hereby irrevocably and unconditionally submits, for
      itself and its property, to the nonexclusive jurisdiction of any Kansas
      State court sitting in the County of Johnson or any Federal court of the
      United States of America sitting in the District of Kansas, and any
      appellate court from any such court, in any suit action, or proceeding
      arising out of or relating to this agreement, or for recognition or
      enforcement of any judgment, and each party hereby irrevocably and
      unconditionally agrees that all claims in respect of any such suit, action
      or proceeding may be heard and determined in such Kansas State Court or,
      to the extent permitted by law, in such Federal court.

            (b) Each party hereby irrevocably and unconditionally waives, to the
      fullest extent it may legally do so, any objection which it may now or
      hereafter have to the laying of venue of any suit, action or proceeding
      arising out of or relating to this agreement in Kansas State court sitting
      in the County of Johnson or any Federal court sitting in the District of
      Kansas. Each party hereby irrevocably waives, to the fullest extent
      permitted by law, the defense of an inconvenient forum to the maintenance
      of such suit, action or proceeding in any such court and further waives
      the right to object, with respect to such suit, action or proceeding, that
      such court does not have jurisdiction over such party.
