Recommended cash offer

for

ArmorGroup International plc

by

G4S (March 2008) Limited

(a wholly-owned subsidiary of G4S plc)

Offer wholly unconditional

On 20 March 2008, the boards of G4S plc (“G4S”) and ArmorGroup International plc
(“ArmorGroup”) announced they had                                               

reached agreement on the terms of a recommended cash offer to be made by G4S    
(March 2008) Limited (“Bidco”), a wholly-owned                                  

subsidiary of G4S, to acquire the entire issued and to be issued share capital  
of ArmorGroup (the "Offer"). The Offer Document was                             

posted to ArmorGroup Shareholders on 31 March 2008 and, on 22 April 2008, Bidco 
announced that the Offer had become                                             

unconditional as to acceptances.

The board of Bidco announces that the Offer is now unconditional in all         
respects. The Offer will remain open for acceptance until                       

further notice.

As at 1.00 pm (London time) on 6 May 2008 Bidco had received valid acceptances  
of the Offer in respect of a total of 50,720,592                                

ArmorGroup Shares, representing approximately 94.93 per cent. of the existing   
issued ordinary share capital of ArmorGroup, the                                

subject of the Offer. Bidco has received acceptances in respect of 1,231,049    
ArmorGroup Shares (representing approximately 2.30                              

per cent. of ArmorGroup's existing issued ordinary share capital) which were    
subject to irrevocable undertakings procured by Bidco                           

from the ArmorGroup Directors (and in the case of Noel Philp and Christopher    
Beese MBE, from the trustees of their beneficially                              

held trusts). In addition, Bidco has received acceptances in respect of         
30,058,645 ArmorGroup Shares (representing approximately                        

56.26 per cent. of ArmorGroup's existing issued ordinary share capital) which   
were subject to irrevocable undertakings procured by                            

Bidco from certain other ArmorGroup Shareholders.

As Bidco has agreed to acquire issued ordinary share capital carrying 75 per    
cent. of the voting rights attached to ArmorGroup                               

Shares, the board of Bidco confirms its intention, as soon as practicable and in
accordance with the terms of the Offer Document, to                             

procure the making of an application by ArmorGroup to the UKLA for the          
cancellation of the listing on the Official List and of                         

admission to trading on the London Stock Exchange of ArmorGroup Shares. If this 
cancellation occurs, it will significantly reduce                               

the liquidity and marketability of ArmorGroup Shares not assented to the Offer. 
It is anticipated that the cancellation of the listing on                       

the Official List and of admission to trading on the London Stock Exchange of   
the ArmorGroup Shares will take effect on a date (not                           

before 5 June 2008), which is at least 20 business days following the date of   
this announcement. Following this, it is also intended                          

that ArmorGroup will be re-registered as a private company under the relevant   
provisions of the Act.
