          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

     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

     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
