|16.2 | The NLFs liability
|---- | -------------------



The NLF will not in any circumstances (whether by reason of taking possession of the Security Assets or for any other reason whatsoever and whether as
mortgagee in possession or on any other basis whatsoever):



| | 16.2.1 | be liable to account to any Obligor or any other person for anything except the NLFs own actual receipts; or
| | ------ | -------------------------------------------------------------------------------------------------------------



| | 16.2.2 | be liable to any Obligor or any other person for any costs, charges, losses, damages, liabilities or expenses arising from or connected with any realisation of the Security Assets
or from any act, neglect, default, omission or misconduct of any nature of the NLF, or any of its officers, employees or agents in relation to the Security Assets, except to the extent that they shall be caused by the fraud or wilful default of the
NLF or any of its respective officers, employees or agents.

The NLF and every Receiver, Delegate, attorney, manager, agent or other person appointed by the NLF under this Deed shall be entitled to be indemnified
out of the Security Assets in respect of all liabilities and expenses incurred by any of them in the execution or purported execution of any of its rights and against all actions, proceedings, costs, claims and demands in respect of any matter or

|17.2 | Default interest
|---- | ----------------



| | 17.2.1 | If any Obligor fails to pay any Secured Liability on its due date, it shall pay to the NLF on demand interest at such rate and calculated on such basis as may be, or have been,
agreed in relation to the relevant Secured Liability or, to the extent not so agreed, at the rate determined by the NLF to be one per cent. per annum higher than the rate which would have been payable if the overdue amount had constituted a loan
with interest at the rate of LIBOR in the currency of the overdue amount for successive interest periods, each of a duration selected by the NLF (acting reasonably). For the purpose of this paragraph (A), LIBOR means the rate per
annum of the offered quotation for sterling deposits for one month which appears on Telerate screen 3750 on the Telerate Monitor Service (or such other page as may replace Page 3750 on that service or such other system as may be nominated by the
British Bankers Association as the information vendor for the purposes of displaying British Bankers Association Settlement Rates) at or about 12 noon (showing the rate as at 11.00a.m.) on the first day of the applicable period.

| | 17.2.2 | Any interest payable under this Clause 17.2 shall accrue from:
| | ------ | --------------------------------------------------------------



| | (a) | in the case of costs, charges, losses, liabilities, expenses and other sums referred to in Clause 18 (Costs and Expenses), the date on which the relevant cost, charge, loss,
liability, expense or sum was expended, paid or debited on account by the NLF without the necessity of any demand being made for payment thereof; or
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | in any other case, the date on which the relevant Secured Liability became due,
| | --- | -------------------------------------------------------------------------------



until full payment and discharge of the relevant Secured Liability (both before and after any judgment).



| | 17.2.3 | Default interest (if unpaid) arising on an overdue amount will be compounded with the overdue amount at the end of each interest period, but will remain immediately due and payable.

from, any delay in paying or omission to pay, any such Tax.



|20. | CURRENCY INDEMNITY
|--- | ------------------



|20.1 | Currency indemnity
|---- | ------------------



If, under any applicable law, whether pursuant to a judgment against an Obligor or the Dissolution of an Obligor or for any other reason, any payment
under or in connection with this Deed is made or falls to be satisfied in a currency (the Other Currency) other than the currency in which the relevant payment is expressed to be payable (the Required Currency),
then, to the extent that the payment actually received by the NLF (when converted into the Required Currency at the rate of exchange on the date of payment or, if it is not practicable for the NLF to make the conversion on that date, at the rate of
exchange as soon afterwards as it is practicable for the NLF to do so or, in the case of a Dissolution, at the rate of exchange on the latest date permitted by applicable law for the determination of liabilities in such Dissolution) falls short of
the amount expressed to be due or payable under or in connection with this Deed, each Obligor shall, as an original and independent obligation under this Deed, indemnify and hold the NLF harmless against the amount of such shortfall.



|20.2 | Rate of exchange
|---- | ----------------



For the purpose of Clause 20.1 (Currency Indemnity), rate of exchange means the rate at which the NLF is able on the relevant
date to purchase the Required Currency with the Other Currency and shall take into account any commission, premium and other costs of exchange and Taxes payable in connection with such purchase.



|21. | CERTIFICATES AND DETERMINATIONS
|--- | -------------------------------



For all purposes, including any Proceedings:



| | 21.1.1 | a determination by the NLF; or

| | 21.1.2 | a copy of a certificate signed by an officer of the NLF,
| | ------ | --------------------------------------------------------

conclusive evidence against any Obligor of the matters to which it relates.
