              Hiscox acquires Kidnap and Ransom business from Aon


Hiscox Ltd, ('Hiscox'), the international specialist insurer, today announced
the acquisition of a portfolio of kidnap and ransom business from Aon Limited,
('Aon'). The business, which is substantially underwritten by Hiscox,
principally comprises Latin American risks from third party intermediaries.

This agreement has been reached following Aon's decision to restructure their
Aon Crisis Management division to focus on servicing business from Aon's network
of global offices. The deal includes a transfer of existing staff and systems
which will ensure a seamless transition for existing clients and brokers.

Hiscox is the market leader for kidnap and ransom insurance by premium income.
