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:

(a)

immediately on demand pay all costs and expenses (including legal fees) incurred in connection with this Deed by any Secured Party, Receiver, attorney, manager, agent or other person appointed by the Security Agent under this Deed including any arising from any actual or alleged breach by any person of any law or regulation, whether relating to the environment or otherwise; and
