                                  RECITALS

            WHEREAS, Company has told Agent and Lenders that:

                  (i) Company wants to issue senior subordinated notes in an
            aggregate principal amount of $200,000,000 (the "UNREGISTERED SENIOR
            SUBORDINATED NOTES");

                  (ii) Company intends to exchange the Unregistered Senior
            Subordinated Notes for registered senior subordinated notes (the
            "REGISTERED SENIOR SUBORDINATED NOTES"; the Unregistered Senior
            Subordinated Notes and the Registered Senior Subordinated Notes are
            collectively referred to herein as the "SENIOR SUBORDINATED NOTES")
            in the same aggregate principal amount and with substantially
            identical terms;

                  (iii) the indenture or indentures pursuant to which the Senior
            Subordinated Notes will be issued will contain provisions, among
            other things, substantially to the effect that (a) if Company sells
            assets and fails, within 365 days, to reinvest the net cash proceeds
            from such sale in the hospitality business or to use such net cash
            proceeds to repay senior indebtedness (including the Obligations),
            the Company will be required to make an offer to the holders of the
            Senior Subordinated Notes and holders of pari passu debt with
            similar asset sale provisions to repurchase the Senior


                                        1
   2
            Subordinated Notes (at a price equal to 100% of the principal
            thereof plus accrued interest thereon plus specified liquidated
            damages, if any) and such other debt in an aggregate amount equal to
            the amount of such net cash proceeds, (b) if a change of control
            with respect to Company occurs, Company will be required to make an
            offer to the holders of the Senior Subordinated Notes to repurchase
            the Senior Subordinated Notes (at a price equal to 101% of the
            principal thereof plus accrued interest plus specified liquidated
            damages, if any) and (c) unless a specified fixed charge coverage
            ratio is satisfied, Company and its Subsidiaries will not incur any
            intercompany indebtedness except indebtedness incurred by Company
            and a restricted Subsidiary that is owed to Company and/or one or
            more of its wholly owned, restricted Subsidiaries (the provisions in
            clauses (a)-(c) being referred to herein as the "SPECIFIED
            PROVISIONS"); and

                  (iv) certain debt Investments made by Company in connection
            with proposed like-kind exchanges under Section 1031 of the Internal
            Revenue Code are, contrary to the provisions of subsection 6.3(c) of
            the Credit Agreement, secured by real property.

            WHEREAS, Company has requested that Agent waive the provisions of
subsections 6.1(a), 6.2D and 6.3(c) in order to permit Company to (i) issue the
Senior Subordinated Notes pursuant to one or more indentures that contain
provisions substantially to the effect of the Specified Provisions and (ii) make
certain debt Investments secured by mortgages on real property and, subject to
the terms and conditions hereof, Agent is willing to consent to such waiver.

            NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, the parties hereto agree as follows:

      Related Lease/Purchase Agreement, (iv) each Related Note, Related
      Mortgage, and Related Lease/Purchase Agreement shall be valid and
      enforceable and satisfactory in form and substance to Agent (provided,

      Agreement that is delivered to Agent and is substantially in the form of
      the Related Notes, Related Mortgages and Related Lease/Purchase
      Agreements, as applicable, delivered to Agent prior to the date hereof
      shall be deemed satisfactory to Agent), (v) at all times during which any
      such Investment exists, Company shall have the right to appoint a member

      other instrument or agreement referred to therein.
