until the Bank receives payment of the whole of the Guaranteed Moneys (both before and
after any demand or judgment or any circumstance which restricts payment by the

    The Bank shall be entitled to retain the benefit of this Guarantee as against the

amount payable in relation to such Guaranteed Moneys after the termination) and the

other security. The Bank shall not be obliged to enforce any other security before
enforcing the guarantee hereunder.
 4.
    
    Customers AccountThe Bank may, at any time and despite the termination of this Guarantee, continue any existing
account and open any new account in the name of the Customer and no subsequent transactions,
receipts or payments involving such new accounts shall affect the liability of the Guarantor.5.
    
    Payments
 5.1
    
    Payments by the Guarantor shall be made to the Bank as specified by the Bank without any
set-off, counterclaim, withholding or condition of any kind except that, if the Guarantor is
compelled by law to make such withholding, the sum payable by the Guarantor shall be
increased so that the amount actually received by the Bank is the amount it would have
received if there had been no withholding.5.2
    
    Payment by the Guarantor to the Bank shall be in the currency of the relevant liability or,
if the Bank so agrees in writing, in a different currency, in which case the conversion to
that different currency shall be made at the Exchange Rate.5.3
    
    No payment to the Bank under this Guarantee pursuant to any judgment, court order or
otherwise shall discharge the obligation of the Guarantor in respect of which it was made
unless and until payment in full has been received in the currency in which it is payable
under this Guarantee and, to the extent that the amount of any such payment shall, on actual
conversion into such currency, at the Exchange Rate, fall short of the amount of the
obligation, expressed in that currency, the Guarantor shall be liable for the shortfall.5.4
    
    Any moneys paid to the Bank in respect of the Guaranteed Moneys may be applied in or towards
satisfaction of the same or placed to the credit of such account as the Bank may determine
with a view to preserving its rights to prove for the whole of the Guaranteed Moneys.5.5
    
    If any moneys paid to the Bank in respect of the Guaranteed Moneys are required to be repaid
by virtue of any law relating to insolvency, bankruptcy or liquidation or for any other
reason, the Bank shall be entitled to enforce this Guarantee as if such moneys had not been
paid.
 6.
    
    Set-offThe Bank may, at any time and without notice, apply any credit balance to which the Guarantor is
entitled on any account with the Bank in or towards satisfaction of the Guaranteed Moneys. For
this purpose, the Bank is authorised to purchase, at the Exchange Rate, such other currencies as
may be necessary to effect such application with the moneys standing to the credit of such
account.7.
    
    Waiver of DefenseThe Guarantor hereby consents and agrees to each of the following, and agrees that its obligations
under this Guarantee shall not be released, diminished, impaired, reduced or adversely affected by
any of the following, and waives any statutory or other rights (including without limitation
rights to notice) which it might otherwise have as a result of or in connection with any of the
following:
 (a)
    
    any amendment to or variation of the terms of the Banking Facilities;(b)
    
    any adjustment, indulgence, forbearance or compromise that might be granted or given by the

    the failure of the Bank or any other party to exercise diligence or reasonable care in the
preservation, protection, enforcement, sale or other handling of all or any part of any
security;(e)
    
    the reorganization, merger or consolidation of the Customer into or with any other person; or(f)
    
    any other action or omission to act which but for this provision would discharge the
Guarantor from any part of its liability under this Guarantee.
 8.
    
    Guarantor as Principal DebtorThe liability of the Guarantor under this Guarantee shall not be discharged or otherwise affected
by reason of the Bank entering into any agreement or arrangement with the Customer or any other
person or by reason of any legal limitation, disability or incapacity or any other act, omission
or circumstance which, but for this provision, would discharge the Guarantor to any extent. Any
Guaranteed Moneys which may not be recoverable from the Customer for any such reason shall be
recoverable by the Bank from the Guarantor as principal debtor by way of indemnity, on demand,
together with Default Interest thereon in accordance with Clause 2.2.9.

on receipt.
 10.
    
    No WaiverNo failure to exercise, nor any delay in exercising, any of the rights or remedies
