Announcement of posting of shareholder circular for the proposed return of
capital of £120 million

On 14 November 2007 Amlin plc ('Amlin') announced its intention to return
approximately £120 million of capital to shareholders (the 'Return of Capital'),
subject to shareholder approval. This equates to 22.4 pence per ordinary share.
It also announced that the Return of Capital will be through an issue of B
Shares, which will give shareholders a choice as to when and in what form they
receive their proceeds.

Amlin has today posted a circular to shareholders ('Circular') containing full
details of the B Share issue and the associated share capital consolidation as
well as a notice convening an Extraordinary General Meeting of the Company to be
held at its offices at 11.30 a.m. on Wednesday 12 December 2007 ('EGM').

A summary of the timetable is as follows. Please note that all events following
the EGM and following admission of the New Shares are conditional upon
shareholder approval being obtained at the EGM and upon admission
(respectively). Further, please note that the record date is 6.00 p.m. on 14
December 2007 (this was incorrectly stated as 14 December 2008 on the previous
announcement).
