		<comment>For the anticipated repayment date mortgage loans: each anticipated repayment date mortgage loan (Asset Number 5 and Asset Number 13) provides that, after the related anticipated repayment date, if the related borrower has not prepaid such mortgage loan in full, then (among other things) any principal outstanding on that date will accrue interest at an increased interest rate rather than the original interest rate.  With respect to the mortgage loan identified as MGM Grand &amp; Mandalay Bay (Asset Number 5), on each payment date following the related anticipated repayment date, up to and including the related maturity date, the borrower will be required to pay to the lender, (i) first, an amount equal to the scheduled monthly debt service payment amount and (ii) second, to the extent of funds available in the excess cash flow reserve account, an amount equal to the monthly additional interest amount (i.e., the amount accrued at the adjusted interest rate minus the amount of interest due as the scheduled monthly debt service payment), provided that if the borrower does not pay any such monthly additional interest amount (such amount not paid, together with interest accrued thereon at the adjusted interest rate, the "Accrued Interest"), the Accrued Interest will remain an obligation of the borrower but the borrower's obligation to pay such Accrued Interest will be deferred and such Accrued Interest will be added to the principal balance of the mortgage loan and will be payable on the maturity date to the extent not sooner paid pursuant to the related mortgage loan agreement.  With respect to the mortgage loan identified as First Republic Center (Asset Number 13), following the related anticipated repayment date, (i) interest at the initial interest rate will continue to accrue and be payable on a current basis, and (ii) interest accrued at the revised rate in excess of interest accrued at the initial interest rate is to be deferred and will be required to be paid only after the outstanding principal balance of the related mortgage loan has been paid in full.</comment>
