(a) For the purposes of all powers implied by statute, the Secured Liabilities are deemed to have become due and payable on the date of this Deed.

(b) Paragraph 11 of the Fourth Schedule to the Property Ordinance does not apply to this Security.

16

11.2 No liability as mortgagee in possession

Neither the Security Agent 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.

11.3 Privileges

Each Receiver and the Security Agent is entitled to all the rights, powers, privileges and immunities referred to in the Property Ordinance as if it were such a mortgagee or receiver (and so that the statutory power of sale shall be exercisable without regard to paragraph 11 of the Fourth Schedule to the Property Ordinance).

11.4 Protection of third parties

No person (including a purchaser) dealing with the Security Agent or a Receiver or its or his agents will be concerned to enquire:

17

12. RECEIVER

12.3 Remuneration

The Security Agent may fix the remuneration of any Receiver appointed by it.

12.4 Agent of the Chargor

(b) Each Secured Party may concede or compromise any claim that any payment, security or other disposition is liable to avoidance or restoration.

19.3 Waiver of defences

The obligations of the Chargor under this Deed will not be affected by any act, omission or thing which, but for this provision, would reduce, release or prejudice any of its obligations under this Deed (whether or not known to the Chargor or any Secured Party). This includes:

23

(c) As from that time all payments made to the Security Agent or any other Secured Party will be credited or be treated as having been credited to the new account and will not operate to reduce any Secured Liability.
