          4.  Section 3.02(d) of the Credit Agreement is hereby amended by (a)
inserting the text "(i) the Casualty Event occurring in September 2001 at the
World Trade Center Marriott in New York, New York and the Financial Center
Marriott in New York, New York or (ii)" in the first parenthetical thereof
immediately after the words "other than" and (b) inserting the following new

     "Promptly upon receipt by the Borrower or any of its Subsidiaries of any
     Net Insurance/Condemnation Proceeds in respect of the Casualty Event
     occurring in September 2001 at the World Trade Center Marriott in New York,
     New York (the "WTC Insurance Proceeds") or the Financial Center Marriott in

     the ground lessor of the respective Hotel Property) and shall include only
     the WTC Insurance Proceeds or the FC Insurance Proceeds, as applicable, and
     shall not be commingled with any other funds of the Borrower or any of its

     repayment and/or commitment reduction in accordance with the requirements
     of Section 3.02(e) or (ii) the Borrower determines that the WTC Insurance
     Proceeds will be applied to replace (consistent with the terms of the then

     agreements) the World Trade Center Marriott, in which case (x) the WTC
     Insurance Proceeds shall be applied solely for the purpose of such
     replacement and (y) upon the completion of such replacement, any WTC
     Insurance Proceeds remaining on deposit in the Segregated WTC Account and
     not otherwise required to fund such replacement shall be applied as a
     mandatory repayment and/or commitment reduction in accordance with the
     requirements of Section 3.02(e).  The FC Insurance Proceeds shall not be
     withdrawn from the Segregated FC Account for any purpose other than to make
     expenditures to restore (consistent with the terms of the then applicable
     insurance, loan documents, ground lease documents and management
     agreements) the Financial Center Marriott.  Upon the completion of such
     restoration, 100% of the FC Insurance Proceeds remaining on deposit in the
     Segregated FC Account and not otherwise required to fund such restoration
     shall be applied as a mandatory repayment and/or commitment reduction in

     entitled at any time (including, without limitation, at the time that any
     funds become required under this Section 3.02(d) to be applied in
     accordance with Section 3.02(e)) to withdraw amounts on deposit in the
     Segregated WTC Account and the Segregated FC Account (to the extent
     permitted by the terms of the applicable insurance, loan documents, ground
     lease documents and management agreements) for the purpose of funding any
     contractual obligations described in clauses (i) through (vi) of the
     definition of "Net Insurance/Condemnation Proceeds" that were not
     previously taken into account in calculating the WTC Insurance Proceeds or
     the FC Insurance Proceeds required to be deposited pursuant to this Section
     3.02(d) into the Segregated WTC Account or the Segregated FC Account, as
     applicable."

          5.  In addition to any other mandatory repayments or commitment
reductions otherwise required pursuant to Section 3.02 of the Credit Agreement,
the Borrower hereby agrees that, within five Business Days after each date on or
