            amended, may be acceptable for registration under applicable law, or
            (2) execute and deliver to the Security Trustee a fresh registrable
            legal mortgage over the Property in favour of the Security Trustee
            in substitution for the Escrow Mortgage in such form as may

            that notwithstanding that the Escrow Mortgage is inoperative as a
            legal mortgage of the Property pending the issue of the Lease or
            other documents of title relating to the Property and registration
            of the Escrow Mortgage, all the covenants, undertakings,
            stipulations, terms and conditions as contained and referred to in
            the Escrow Mortgage shall be deemed to have full force and effect as
            if they were contained and referred to in this Assignment with the

            one document, and the Assignor hereby covenants to perform and
            observe all such covenants, undertakings, stipulations, terms and
            conditions contained and referred to in the Escrow Mortgage.

            credit of the new or separate account or accounts so opened or
            deemed to have been opened as aforesaid and shall not go in
            reduction of any part of the Secured Obligations at the time of
            notice. Nothing contained in this Clause 4.3 shall prejudice the
            security which the Security Trustee otherwise would have had under
            this Assignment for the payment of the moneys costs charges and
            expenses secured or intended to be secured by this Assignment
            notwithstanding that the same may become due or owing or be incurred
            after the time of notice.

      4.4   SUSPENSE ACCOUNT: All moneys received, recovered or realised by the
            Security Trustee under this Assignment (including, without
            limitation, the proceeds of any conversion of currency) may at the
            discretion of the Security Trustee be credited to any suspense or
            impersonal account and may be held in such account for so long as
            the Security Trustee may think fit (without liability to pay
            interest thereon) pending their application from time to time (as
            the Security Trustee shall be entitled to do its discretion) in or
            towards the discharge of any part of the Secured Obligations;
            provided, however, that if the Security Trustee does not apply any
            such amounts to the discharge of the Secured Obligations, the
            Security Trustee shall be deemed to have waived its right to receive
            interest at the Default Rate otherwise payable on the portion of the
            Secured Obligations that could otherwise be discharged by virtue of
            such application.

                  Borrower or to take the benefit of or to enforce any Security
                  Interest in respect of all or any part of the Secured
                  Obligations;

            4.5.2 any right or proof of the Assignor in the winding up of the
                  Borrower in respect of any indebtedness whatsoever shall be
                  exercised and enforced by it only in such manner and on such
                  terms as the Security Trustee may require; and

            4.5.3 any amount received or recovered by the Assignor as a result
                  of any exercise by it of any such right shall be immediately
                  paid to the Security Trustee.

            other provision.
