              -------------------------------------------------  
Notwithstanding anything to the contrary contained in the Credit Agreement, the
following provisions shall apply with respect to those ground leases with
respect to which Landlord Consents are required but have not been obtained.  If
any litigation commences with respect to any such ground lease as a result of
the failure to obtain the applicable Landlord Consent and a final judgment is
rendered against the Borrower or its applicable Subsidiary in such litigation
(whether or not such judgment is appealable) and the result of such judgment is
that the Borrower or its applicable Subsidiary either is required to pay damages
of $1,000,000 or more or the applicable ground lease is terminated and the
Borrower or its applicable Subsidiary must vacate the respective Hotel Property,
then:

                                      -6-

 
          (i)   if only one (1) such ground lease is subject to such an adverse
judgment, then for purposes of determining Consolidated EBITDA under the Credit
Agreement, fifty percent (50%) of the portion of such Consolidated EBITDA
attributable to all ground leases subject to any such litigation (whether or not
any adverse judgment has been rendered) shall be excluded from such calculation;

          (ii)  if two (2) such ground leases are subject to such an adverse
judgment, then for purposes of determining Consolidated EBITDA under the Credit
Agreement, seventy-five percent (75%) of the portion of such Consolidated EBITDA
attributable to all ground leases subject to any such litigation (whether or not
any adverse judgment has been rendered) shall be excluded from such calculation;

          (iii) if three (3) such ground leases are subject to such an adverse
judgment, then for purposes of determining Consolidated EBITDA under the Credit
Agreement, all of such Consolidated EBITDA attributable to all ground leases
subject to any such litigation (whether or not any such adverse judgment has
been rendered) shall be excluded from such calculation; and

          (iv)  if it is determined in a final judgment of a court of competent
jurisdiction that the Borrower or its applicable Subsidiary must vacate a Hotel
Property or the Borrower or its applicable Subsidiary consents thereto in
writing, following the date on which any such final judgment is no longer being
appealed and all rights of appeal have been exhausted, then, in addition to the
provisions of the preceding clauses (i), (ii) or (iii), as applicable, one-
hundred percent (100%) of the portion of Consolidated EBITDA attributable to
such Hotel Property shall be excluded from the calculation of Consolidated
EBITDA under the Credit Agreement.

          (c)   Default Upon Termination of Ground Leases.  Notwithstanding
                -----------------------------------------                  
anything to the contrary contained in the Credit Agreement, upon the effective
termination of a ground lease listed on Schedule XIII and the loss by the
                                        -------------                    
Borrower or its applicable Subsidiary of the right to the continued use of the
respective Hotel Property (as finally determined by a court of competent
jurisdiction and after such final judgment is no longer being appealed or all
rights of appeal have been exhausted or as otherwise consented to in writing by
the Borrower or such Subsidiary, as the case may be) as a result of a failure to
obtain the applicable Landlord Consent, it shall be an Event of Default if the
sum of:

                (i)  the amount of Consolidated EBITDA attributable to the Hotel
Property which was subject to such ground lease, determined for the most
recently ended Test Period; plus

                (ii) the amount of Consolidated EBITDA attributable to each
other Hotel Property which was subject to a ground lease listed on

                                      -7-

 
Schedule XIII and which was effectively terminated or with respect to which the
- -------------
Borrower or its applicable Subsidiary lost the right to the continued use of the
respective Hotel Property (as finally determined by a court of competent
jurisdiction and after such final judgment is no longer being appealed or all
rights of appeal have been exhausted or as otherwise consented to in writing by
the Borrower or such Subsidiary, as the case may be) as a result of a failure to
obtain the applicable Landlord Consent, determined for each such Hotel Property
for the Test Period ending on the most recent March 31, June 30, September 30 or
December 31 occurring prior to the effective termination of such ground lease;

exceeds five percent (5%) of Consolidated EBITDA for the most recently ended
Test Period (without giving effect to any reduction in such Consolidated EBITDA
pursuant to paragraph 7(b) above).
