IT IS AGREED as follows:



| | 1 | Definitions and interpretation

|1.1 |  | Terms defined in the Facility Agreement have, unless defined differently in this Deed, the same meaning
when used in this Deed. In addition, in this Deed:
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------



Facility Agreement means
the agreement described in Schedule 1 as it may from time to time be amended, restated, novated or replaced (however fundamentally,
including by an increase of any size in any facility made available under it, the alteration of the nature, purpose or period of
any such facility or the change of its parties).



Secured Obligations means
the indebtedness and obligations undertaken to be paid or discharged by the Obligors under the Finance Documents.



|1.2 |  | Clauses 1.2 (Construction), 1.3 (Third party rights) and 1.4 (Finance Documents)
of the Facility Agreement and any other provision of the Facility Agreement which, by its terms, purports to apply to all of the
Finance Documents and/or any Obligor shall apply to this Deed as if set out in it but with all necessary changes and as if references
in the provision to Finance Documents referred to this Deed. For the avoidance of doubt, by virtue of clause 1.4 (Finance Documents)
of the Facility Agreement, the Guarantor confirms that the representations and warranties concerning the Guarantor and/or this
Deed made or deemed repeated under the Facility Agreement are true and correct.
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 2 | Guarantee
| | - | ---------



|2.1 |  | The Guarantor irrevocably and unconditionally:
|--- |  | ----------------------------------------------



| | (a) | guarantees to the Mortgagee that it shall, on demand by the Mortgagee, immediately pay or otherwise
discharge the Secured Obligations of each other Obligor;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | undertakes with the Mortgagee that whenever another Obligor does not pay or discharge any of the Secured

principal obligor; and
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | agrees on demand to immediately indemnify the Mortgagee against any cost, loss or liability suffered
by the Mortgagee if any obligation guaranteed by it is or becomes unenforceable, invalid, void or illegal for any reason and the
amount of the cost, loss or liability shall be equal to the amount which the Mortgagee would otherwise have been entitled to recover.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------







|2.2 |  | Nothing in clause 2.1 shall be construed as constituting a guarantee by any Obligor of its own obligations.

|2.3 |  | The undertakings of the Guarantor under this clause 2 and the other provisions of this Deed are given
to the Mortgagee as agent and trustee for the Finance Parties.

| | 4 | Guarantee protections
| | - | ---------------------



|4.1 |  | This Deed and the obligations of the Guarantor under this Deed are a continuing and independent guarantee
and shall extend to the ultimate balance owing in respect of the Secured Obligations, regardless of any intermediate payment or
discharge in whole or in part.
|--- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.2 |  | If any payment by an Obligor or any discharge given by a Finance Party (whether in respect of the

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



| | (a) | the liability of the Guarantor under this Deed shall continue as if the payment, release, avoidance
or reduction had not occurred; and
| | --- | --------------------------------------------------------------------------------------------------------------------------------------



| | (b) | the Mortgagee shall be entitled to recover the value or amount of that security or payment from the
Guarantor, as if the payment, discharge, avoidance or reduction had not occurred.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.3 |  | The obligations of the Guarantor under this Deed shall not be affected by any act, omission, matter
or thing which, but for this clause, would reduce, release or prejudice any of its obligations under this Deed (without limitation

with any creditor of any other Obligor;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | the taking, variation, compromise, exchange, renewal or release of, or refusal or neglect to perfect,
take up or enforce, any rights against, or security over assets of, any Obligor or other person or any non-presentation or non-observance
of any formality or other requirement in respect of any instrument or any failure to realise the full value of any security;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

members or status of, any Obligor or any other person;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------



| | (e) | any amendment, novation, supplement, extension, restatement (however fundamental and whether or not
more onerous) or replacement of any Finance Document or any other document or security;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (f) | any unenforceability, illegality or invalidity of any obligation of any person under any Finance Document
or any other document or security; or
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------



| | (g) | any insolvency or similar proceedings.
| | --- | --------------------------------------



|4.4 |  | The Guarantor waives any right it may have of first requiring the Mortgagee or any other Finance Party
(or any trustee or agent on its behalf) to proceed against or enforce any other rights or security or claim payment from any person
before claiming from the Guarantor under this Deed. This waiver applies irrespective of any law or any provision of a Finance Document
to the contrary.
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.5 |  | Until the Secured Obligations have been irrevocably and unconditionally discharged in full, the Mortgagee
and each other Finance Party (or any trustee or agent on its behalf) may:
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | refrain from applying or enforcing any other money, security or rights held or received by it (or
any trustee or agent on its behalf) in respect of the Secured Obligations, or apply and enforce the same in the manner and order
it thinks fit (whether against those amounts or otherwise) and the Guarantor shall not be entitled to the benefit of the same;
and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | hold in an interest-bearing suspense account any money received from the Guarantor or on account of
its liability under this Deed.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------



|4.6 |  | Until all the Secured Obligations have irrevocably and unconditionally been paid in full and unless
the Mortgagee otherwise directs, the Guarantor shall not exercise any rights (including rights of set-off) which it may have by
reason of performance by it of its obligations under the Finance Documents:
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) | to be indemnified or reimbursed by another Obligor;
| | --- | ---------------------------------------------------



| | (b) | to claim any contribution from any other guarantor of any Obligor’s obligations under the Finance
Documents; or
| | --- | ---------------------------------------------------------------------------------------------------------------



| | (c) | to take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights
of the Finance Parties under the Finance Documents or of any other guarantee or security taken pursuant to, or in connection with,
the Finance Documents by any Finance Party.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If the Guarantor receives any
benefit, payment or distribution in relation to such rights it will promptly pay an equal amount to the Mortgagee for application
in accordance with clause 33 (Payment mechanics) of the Facility Agreement. This only applies until all amounts which may
be or become payable by the Obligors under or in connection with the Finance Documents have been irrevocably paid in full.

the Mortgagee otherwise directs, the Guarantor shall be entitled to declare and pay dividends or other distributions or payments
(whether in cash or in specie), including any interest and/or unpaid dividends, to its shareholders, in respect of its equity or

listed on an Approved Exchange.
