The security constituted by this Debenture shall become immediately enforceable upon the occurrence and continuance of an Event of Default and the power
of sale and other powers conferred by Section 101 of the Act, as varied or amended by this Debenture, shall be immediately exercisable upon and at any time after the occurrence and continuance of any Event of Default. After the security constituted

|10. | ENFORCEMENT OF SECURITY
|--- | -----------------------



|10.1 | General
|---- | -------



For the purposes of all powers implied by statute, the Secured Liabilities and Deed of Payment Liabilities are deemed to have become due and payable on
the date of this Debenture and Section 103 of the Act (restricting the power of sale) and Section 93 of the Act (restricting the right of consolidation) do not apply to the security constituted by this Debenture. The statutory powers of leasing
conferred on the Security Trustee are extended so as to authorise the Security Trustee to lease, make agreements for leases, accept surrenders of leases and grant options as the Security Trustee may think fit and without the need to comply with any
provision of section 99 or 100 of the Act.



|10.2 | Shares
|---- | ------



After the security constituted by this Debenture has become enforceable, the Security Trustee may exercise (in the name of the Chargor and without any
further consent or authority on the part of the Chargor) any voting rights and any powers or rights which may be exercised by the person or persons in whose name any Share and its Related Rights are registered or who is the holder of any of them or
otherwise (including all the powers given to trustees by Section 10(3) and (4) of the Trustee Act, 1925 as amended by Section 9 of the Trustee Investment Act, 1961 in respect of securities or property subject to a trust). Until that time, the voting
rights, powers and other rights in respect of the Shares shall (if exercisable by the Security Trustee) be exercised in any manner which the Chargor may direct in writing.



|10.3 | Contingencies
|---- | -------------



If the Security Trustee enforces the security constituted by this Debenture at a time when no amounts are due under the Finance Documents, the
Subordinated Loan Agreement or the Deed of Payment but at a time when amounts may or will become so due, the Security Trustee (or the Receiver) may pay the proceeds of any recoveries effected by it into a Security Account.



|10.4 | No liability as mortgagee in possession
|---- | ---------------------------------------



Neither the Security Trustee nor any Receiver will be liable, by reason of entering into possession of a Security Asset, to account as mortgagee in
possession or for any loss on realisation or for any default or omission for which a mortgagee in possession might be liable.



|10.5 | Security Trustee of the Chargor
|---- | -------------------------------



Each Receiver is deemed to be the agent of the Chargor for all purposes and accordingly is deemed to be in the same position as a Receiver duly appointed
by a mortgagee under the Act. The Chargor alone shall be responsible for his contracts, engagements, acts, omissions, defaults and losses and for liabilities incurred by him and the Finance Parties, BE and/or BET shall not incur any liability
(either to the Chargor or to any other person) by reason of the Security Trustee making his appointment as a Receiver or for any other reason.



19



---

|10.6 | Privileges

| | (b) | whether any power which the Security Trustee or the Receiver is purporting to exercise has become exercisable; or
| | --- | -----------------------------------------------------------------------------------------------------------------



| | (c) | whether any money remains due under the Finance Documents, the Subordinated Loan Agreement or the Deed of Payment; or

| | (d) | how any money paid to the Security Trustee or to the Receiver is to be applied.
| | --- | -------------------------------------------------------------------------------



|10.8 | Redemption of prior Mortgages
|---- | -----------------------------



At any time after the security constituted by this Debenture has become enforceable, the Security Trustee may:



| | (a) | redeem any prior Security Interest against any Security Asset; and/or
| | --- | ---------------------------------------------------------------------



| | (b) | procure the transfer of that Security Interest to itself; and/or
| | --- | ----------------------------------------------------------------



| | (c) | settle and pass the accounts of the prior mortgagee, chargee or encumbrancer; any accounts so settled and passed shall be conclusive and binding on the Chargor.
