|11. | RECEIVER
|--- | --------



|11.1 | Upon the occurrence of the Demand Date or if a petition or application is presented for the making of an administration order in relation to the Assignor or if any person who is
entitled to do so gives written notice of its intention to appoint an administrator of the Assignor or files such a notice with the court, the Assignee may by writing (acting through an authorised officer of the Assignee) without notice to the

respect of which he was appointed, all the powers (a) conferred by the Law of Property Act 1925 on a receiver appointed under that Act; (b) of an administrative receiver set out in Schedule 1 to the Insolvency Act 1986 (whether or not such person is
an administrative receiver); and (c) (if such person is an administrative receiver) all the other powers exercisable by an administrative receiver in relation to the Assignor by virtue of the Insolvency Act 1986.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12. | EFFECTIVENESS OF SECURITY
|--- | -------------------------



|12.1 | The security created by this Assignment and the Collateral Rights shall be cumulative, in addition to and independent of every other security which the Assignee may at any time hold
for the Secured Obligations or any rights, powers and remedies provided by law. No prior security held by the Assignee over the whole or any part of the Assigned Property shall merge into the security constituted by this Assignment.
|---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|12.2 | This Assignment shall remain in full force and effect as a continuing security for the Secured Obligations unless and until the Assignee discharges it.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------



|12.3 | No failure on the part of the Assignee to exercise, or delay on its part in exercising, any Collateral Right shall operate as a waiver, nor shall any single or partial exercise of a
Collateral Right prevent any further or other exercise of that or any other Collateral Right.

|13.1 | Upon the Secured Obligations being discharged in full and the Assignee having no actual or contingent obligation under the Second Intercompany Loan Agreement, the Assignee shall, at
the request and expense of the Assignor, reassign to the Assignor the Assigned Property, subject to Clause 13.2 and without recourse to, or any representation or warranty by, the Assignee.

Assignee received notice.



|15. | APPLICATION OF MONEYS
|--- | ---------------------



All moneys received or recovered by the Assignee or any receiver appointed pursuant to this Assignment or the powers conferred by it shall (subject to the
claims of any person having prior rights thereto and by way of variation of the provisions of the Law of Property Act 1925) be applied first in the payment of the costs, charges and expenses incurred and payments made by such receiver, the payment
of his remuneration and the discharge of any liabilities incurred by such receiver in, or incidental to, the exercise of any of his powers, and thereafter shall be applied by the Assignee (notwithstanding any purported appropriation by the Assignor)

| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | in payment to the credit of any suspense or impersonal account for so long as the Assignee shall think fit pending any further application of such moneys (as the Assignee shall be
entitled, but not obliged, to do in its discretion) in accordance with the previous provisions of this Clause; and
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | if the Assignor is under no further actual or contingent liability under the Second Intercompany Loan Agreement, in payment of the surplus to the Assignor or any other person
entitled thereto.
