            amended, supplemented or otherwise modified from time to time."

            restoration, replacement or rebuilding, in the case of each of (x)
            and (y), subject to force majeure; or (ii) if no Event of Default
            has occurred and is continuing and the amount of Net Proceeds
            received (or reasonably anticipated by the Borrower to be received)
            in connection with such damage, destruction or loss is $50,000,000
            or greater, then the Borrower shall cause such Net Proceeds to be
            deposited in a segregated account at a bank (which need not be a
            Lender) selected by the Borrower, and the Borrower hereby covenants
            and agrees that such Net Proceeds shall be withdrawn from such
            segregated account and applied solely for the purpose of, and in the
            amounts necessary to, make required payments in connection with the
            restoration, replacement or rebuilding, in whole or in part, of the
            portion of such Property so damaged, destroyed or lost or to the
            prepayment of the Loans and, to the extent the Loans have been paid
            in full, the Additional Loans, provided, however, that the Borrower
            shall be required to apply such Net Proceeds to the prepayment of
            the Loans (x) if the Borrower shall have failed to commence the
            restoration, replacement or rebuilding, in whole or in part, of the

            majeure."

    substituting in lieu thereof a new clause (d) to read in its entirety as
    follows:

            part or interest therein or any similar event with respect thereto,

            the Borrower to be received) in connection with such condemnation or
            similar event is less than $50,000,000, then the Borrower may retain

            Proceeds to the replacement, in whole or in part, of such Property
            or such part thereof so condemned or to the prepayment of the Loans
            and, to the extent the Loans have been paid in full, the Additional
            Loans, provided, however, that the Borrower shall be required to
            apply such Net Proceeds to the prepayment of the Loans (x) if the

            Property or such part thereof so condemned within six months
            following the receipt of such Net Proceeds or (y) if the Borrower
            shall cease to be diligently continuing such replacement, in the
            case of each of (x) and (y), subject to force majeure; or (ii) if no
            Event of Default has occurred and is continuing and the amount of

            be received) in connection with such condemnation or similar event
            is $50,000,000 or greater, then the Borrower shall cause such Net
            Proceeds to be deposited in a segregated account at a bank (which
            need not be a Lender) selected by the Borrower, and the Borrower
            hereby covenants and agrees that such Net Proceeds shall be
            withdrawn from such segregated account and applied solely for the
            purpose of, and in the amounts necessary to, make required payments
            in connection with the replacement of such Property or such part
            thereof so condemned or to the prepayment of the Loans and, to the
            extent the Loans have been paid in full, the Additional Loans,
            provided, however, that the Borrower shall be required to apply such
            Net Proceeds to the prepayment of the Loans (x) if the Borrower
            shall have failed to commence the replacement of such Property or
