Further to its announcement earlier today, 19 September 2006, Senior plc
('Senior') announces that a combined prospectus and circular (the 'Prospectus')

despatched to Qualifying non-CREST Shareholders and Nil Paid Rights credited to
stock accounts in CREST on 20 September 2006, in each case subject to certain
exceptions.

The Rights Issue is expected to raise proceeds of approximately £27.3 million
(before expenses) and to result in the issue of 64,960,962 New Ordinary Shares
(representing approximately 16.7 per cent. of the Enlarged Share Capital).

The Prospectus includes a notice convening the Extraordinary General Meeting to
be held at 10.00 a.m. on 5 October 2006 at the offices of ABN AMRO, 250

to approve the Acquisition and The Senior plc 2006 Savings-Related Option
Scheme.

Shares (nil and fully paid) to be admitted to the Official List and to the
London Stock Exchange for the New Ordinary Shares (nil and fully paid) to be
admitted to trading on the London Stock Exchange's main market for listed

dealings in the New Ordinary Shares will commence on the London Stock Exchange,
nil paid, at 8.00 a.m. on 20 September 2006. It is expected that dealings in the
New Ordinary Shares, fully paid, will commence on the London Stock Exchange at
