          "(i) on assets of the Parent and its Subsidiaries approved by the
     Administrative Agent as additional security for the Obligations which
     secure Additional Designated Senior Indebtedness (and to the extent
     securing Additional Designated Senior Indebtedness, such Liens may also
     secure the Other Existing Senior Indebtedness), provided that such Liens
                                                     --------
     (i) also secure the Obligations on an equal and ratable basis with such

     stock, limited liability company interests and partnership interests in
     Subsidiaries of the Parent that constitutes Collateral, and (iii) are
     granted pursuant to documentation (including documentation granting Liens
     to secure the Obligations on an equal and ratable basis) reasonably
     acceptable to the Administrative Agent and the Borrower."

     24. From and after the Amendment Date, notwithstanding the definitions of
"Secured Non-Recourse Indebtedness", "Secured Recourse Indebtedness" and
"Unsecured Indebtedness" to the contrary, any Additional Designated Senior
Indebtedness and Other Existing Senior Indebtedness which is secured by Liens on
assets of the Parent and its Subsidiaries permitted by the provisions of Section
6.01(i) of the Credit Agreement shall be deemed "Unsecured Indebtedness" for
purposes of the financial covenants and other covenants limiting such types of
Indebtedness, notwithstanding the granting of the permitted Liens to secure such
Additional Designated Senior Indebtedness and Other Existing Senior
Indebtedness.

     25. From and after the Amendment Date, Section 6.11 of the Credit Agreement
is amended by deleting the period at the end of Section 6.11 and adding the
following provisions at the end of such Section 6.11:

     "provided that in connection with the incurrence of Additional Designated
      --------
     Senior Indebtedness of the Parent and its Subsidiaries permitted by the
     provisions of this Agreement the Parent and its Subsidiaries may enter into
     such agreements which (x) are in form and substance acceptable to the
     Administrative Agent in its reasonable discretion, (y) would require the
     Parent and its Restricted Subsidiaries (as defined in the Indenture for
     such Additional Designated Senior Indebtedness) to comply with a financial
     covenant that such Persons' total unencumbered assets to total senior
     unsecured Indebtedness exceed 150%, provided that the pledging of Liens on
     Hotel Properties for the equal and ratable benefit of the Obligations, the
     Additional Designated Senior Indebtedness and the Other Existing Senior
     Indebtedness would not be prohibited in any way notwithstanding

                                       11

<PAGE>

     such financial covenant, and (z) would require that assets of the Parent
     and its Subsidiaries (other than the existing Collateral and any future
     capital stock, limited liability company interests and partnership
     interests in Subsidiaries of the Parent that constitutes Collateral) which
     secure the Obligations or any other Senior Indebtedness of the Parent
     (excluding (i) existing Secured Recourse Indebtedness [except for the
     Obligations] and Secured Non-Recourse Indebtedness, (ii) any refinancings
     thereof, (iii) up to $300,000,000 of other Senior Indebtedness which is
     either a commercial mortgaged back securities facility or Secured
     Non-Recourse Indebtedness, and (iv) any other new such Indebtedness
     permitted under the financial covenants governing such Additional
     Designated Senior Indebtedness without the granting of Liens to secure such
     Additional Designated Senior Indebtedness) also secure on an equal and
     ratable basis such Additional Designated Senior Indebtedness. In connection
     with the incurrence of Additional Designated Senior Indebtedness of the
     Parent and its Subsidiaries permitted by the provisions of this Agreement,
     the Indenture for the Other Existing Senior Indebtedness may be amended in
     a manner reasonably acceptable to the Administrative Agent to add covenants
     consistent with the provisions of the preceding clauses (y) and (z). The
     foregoing provisions shall in no way make effective Sections 4.12 or 4.18
     of the Indenture for the Other Existing Senior Indebtedness."

     26. From and after the Amendment Date, the form of Compliance Certificate
shall be revised in a manner reasonably acceptable to the Borrower and the
Administrative Agent to include the changes to the Credit Agreement set forth in
this Amendment, including without limitation, the additional financial covenant
and the limitations on Revolving Advances.

     27. The Borrower agrees that notwithstanding anything to the contrary
contained in the Credit Agreement, as soon as available, and in any event no
later than the last day of the following month after the end of every fiscal
month during the Amendment Period, the Borrower shall provide the Administrative
Agent (for distribution to the Lenders) liquidity, cash flow and summary
operating information for such fiscal month prepared by the Borrower in a form
reasonably satisfactory to the Administrative Agent.

     28. This Amendment is limited as specified and shall not constitute a
modification, acceptance or amendment of any other provision of the Credit
Agreement or any other Credit Document.

     29. Each party hereto represents to the other parties hereto that such
party is authorized to execute this Amendment.

     30. The Borrower and the Guarantors represent and warrant to the Lenders
and the Agents that:

         a. the representations and warranties contained in this Amendment, and
     in each Credit Document are true and correct in all material respects as of
     the Amendment Date except for changes which individually or in the
     aggregate do not constitute a Material Adverse Change;

         b. no Default or Event of Default exists as of the Amendment Date
     except for

                                       12

<PAGE>

     any such Default or Event of Default as is expressly waived or eliminated
     by this Amendment; and

          c. such Persons have no claims, offsets, or counterclaims with respect
     to their respective obligations under the Credit Documents as of the
     Amendment Date.
