4 April 2008                                                                    
Recommended cash offer for ArmorGroup International plc (“ArmorGroup”) by G4S   
(March 2008) Limited (“Bidco”) (a wholly-owned subsidiary of G4S plc (“G4S”))   
Further to the announcement made on 20 March 2008 of the recommended cash offer 
for ArmorGroup by Bidco (the “Announcement”), G4S discloses, in accordance with 
Rule 8.4 of the Code, that Bidco has obtained irrevocable undertakings from     
Charles Russell Trustees (UK) Ltd (“Charles Russell Trustees”), acting as       
trustees of Beese Family Trust, and from Charles Russell Trustees, acting as    
trustees of the N Philp Trust, to accept, or to procure the acceptance of, the  
Offer in respect of their beneficial ArmorGroup shareholdings totalling 287,731 
and 768,448 ArmorGroup Shares, respectively.                                    
As announced by ArmorGroup on 4 April 2008, Christopher Beese transferred       
287,731 ArmorGroup Shares to Beese Family Trust on 3 April 2008. The irrevocable
undertaking obtained from Charles Russell Trustees, acting as trustees of Beese

transferred to Beese Family Trust by Christopher Beese on 3 April 2008.         
As also announced by ArmorGroup on 4 April 2008, Noel Philp transferred 768,448 
ArmorGroup Shares to N Philp Trust on 3 April 2008. The irrevocable undertaking 
obtained by Charles Russell Trustees, acting as trustees of N Philp Trust, is in

The undertakings from the trustees of Beese Family Trust and the trustees of N  
Philp Trust will continue to apply in the event that the Offer is implemented by
way of a scheme of arrangement. These undertakings will remain binding in the   
event of a competing offer being made in relation to ArmorGroup unless the Offer
lapses or is withdrawn.                                                         
Consequentially, the irrevocable undertakings signed by Christopher Beese and   
Noel Philp, as outlined in the Offer Document, are no longer binding, in so far 
as they relate to the ArmorGroup Shares transferred. In all other respects they 
remain in full force and effect.
