                                       by                                       
        G4S (March 2008) Limited (a wholly-owned subsidiary of G4S plc)         

Summary                                                                         

The boards of directors of G4S and ArmorGroup are pleased to announce that they 
have reached agreement on the terms of a recommended cash offer for ArmorGroup  
by Bidco (a wholly-owned subsidiary of G4S) at a price of 80 pence in cash for  
each ArmorGroup Share, valuing the entire issued and to be issued share capital 
of ArmorGroup at approximately £43.6 million.                                   

ArmorGroup's proposed final dividend in respect of the year ended 31 December   
2007 of 1.5 pence per ArmorGroup Share, announced by ArmorGroup today, is       
included in the Offer Price and hence such final dividend will not be paid if   
the Offer becomes or is declared wholly unconditional.                          

G4S is the world's leading international security solutions group, which        
specialises in assessing current and future risks and developing secure         
solutions to minimise their impact across a wide range of geographic markets and
business sectors. G4S is a major provider of risk management and protection to  
governments and major corporate customers around the world and is an expert in  
all aspects of local and international secure logistics.                        

ArmorGroup is a leading provider of defensive, protective security services to  
national governments, multinational corporations and international peace and    
security agencies operating in hazardous environments.  It has approximately    
8,500 employees and 38 offices in 27 countries.                                 

The price of 80 pence for each ArmorGroup Share represents:                     

a premium of approximately 127.0 per cent. to 35.25 pence, being the Closing    
Price per ArmorGroup Share on 26 February 2008, the Business Day prior to       
ArmorGroup's announcement that it was in discussions with a number of parties   
regarding a possible offer for ArmorGroup; and                                  

a premium of approximately 156.8 per cent. to 31.15 pence, being the average    
Closing Price per ArmorGroup Share over the three month period up to and        
including 26 February 2008.                                                     

The ArmorGroup Board, which has been so advised by Rothschild, considers the    
terms of the Offer to be fair and reasonable.  In providing its advice,         
Rothschild has taken into account the commercial assessments of the ArmorGroup  
Directors.  Accordingly, the ArmorGroup Board intends unanimously to recommend  
that ArmorGroup Shareholders accept the Offer, as the ArmorGroup Directors who  
hold ArmorGroup Shares have themselves irrevocably undertaken to do in respect  
of their own beneficial holdings (and, where applicable, those of their wives)  
totalling, in aggregate, 1,231,049 ArmorGroup Shares, representing approximately
2.30 per cent. of ArmorGroup's existing issued share capital.                   

Bidco has also received irrevocable undertakings from Baird Capital Partners    
Europe Limited, Industrial & Financial Investments Co. and Lansdowne Partners   
Limited to accept, or procure the acceptance of, the Offer in respect of their  
entire ArmorGroup shareholdings totalling, in aggregate, 27,096,842 ArmorGroup  
Shares, representing approximately 50.73 per cent. of ArmorGroup's existing     
issued share capital.                                                           

Accordingly, Bidco has received, in aggregate, irrevocable undertakings to      
accept the Offer in respect of 28,327,891 ArmorGroup Shares representing        
approximately 53.03 per cent. of ArmorGroup's existing issued share capital.    

Commenting on today's announcement, Nick Buckles, Chief Executive Officer of    
G4S, said:                                                                      

“The acquisition of ArmorGroup represents an important and logical step in      
delivering our strategy for accelerated growth and development and we are       
pleased that the ArmorGroup Board has decided to unanimously recommend the      
Offer.  ArmorGroup's experience in providing protective security and other      
related services, its international presence and strong customer relationships  
means that it is a natural fit with our existing business.”                     

Commenting on the Offer, Sir Malcolm Rifkind, Chairman of ArmorGroup, said:     

“The Offer by Bidco announced today gives ArmorGroup shareholders the prospect  
of a cash exit at an attractive price when considered against the potential of  
ArmorGroup as a standalone business.  The ArmorGroup Board believes that Bidco's
Offer is full and fair and, accordingly, the ArmorGroup Board is pleased to     
recommend it to shareholders.                                                   

The ArmorGroup Board also believes that G4S's proven track record of integrating
and developing companies it has acquired, its strong management and financial   
resources and its commitment to high quality operating standards will help to   
strengthen ArmorGroup's position in what continues to be a developing market.”  

Greenhill is acting as financial adviser to G4S and Rothschild is acting as     
financial adviser to ArmorGroup.

This Announcement has been prepared for the purposes of complying with English  
law, the City Code and the Listing Rules and information disclosed may not be   
the same as that which would have been disclosed if this Announcement had been  
prepared in accordance with the laws of jurisdictions outside                   
England.                                                                        

The Offer will be subject to the applicable rules and regulations of the

Dealing Disclosure Requirements                                                 

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes,     
"interested" (directly or indirectly) in 1% or more of any class of "relevant   
securities" of ArmorGroup, all "dealings" in any "relevant securities" of that  
company (including by means of an option in respect of, or a derivative         
referenced to, any such "relevant securities") must be publicly disclosed by no 
later than 3.30 p.m. (London time) on the Business Day following the date of the
relevant transaction. This requirement will continue until the date on which the
Offer becomes, or is declared, unconditional as to acceptances or is otherwise  
withdrawn or on which the "offer period" otherwise ends. If two or more persons 
act together pursuant to an agreement or understanding, whether formal or       
informal, to acquire an "interest" in "relevant securities" of ArmorGroup, they 
will be deemed to be a single person for the purpose of Rule 8.3.               

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant       
securities" of ArmorGroup by Bidco, G4S or ArmorGroup, or by any of their       
respective "associates", must be disclosed by no later than 12.00 noon (London  
time) on the Business Day following the date of the relevant transaction.       

A disclosure table, giving details of the companies in whose "relevant          
securities" "dealings" should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.      

"Interests in securities" arise, in summary, when a person has long economic    
exposure, whether conditional or absolute, to changes in price of securities. In
particular, a person will be treated as having an "interest" by virtue of the   
ownership or control of securities, or by virtue of any option in respect of, or
derivative referenced to, securities.                                           

Terms in quotation marks are defined in the Code, which can also be found on the
Panel's website. If you are in any doubt as to whether or not you are required  
to disclose a "dealing" under Rule 8 of the Code, you should contact an         
independent financial adviser authorised under the Financial Services and       
Markets Act 2000 or consult the Panel's website or contact the Panel on         
telephone number +44 (0)20 7638 0129.

2.	The Offer                                                                    

The Offer, which will be subject to the conditions and further terms set out in 
Appendix I to this Announcement and to be set out in the Offer Document and (in 
the case of ArmorGroup Shareholders who hold their ArmorGroup Shares in         
certificated form) the Form of Acceptance, will be made on the following basis: 

                  for each ArmorGroup Share		80 pence in cash                   

The Offer values the entire issued and to be issued share capital of ArmorGroup 
at approximately £43.6 million and represents:                                  

a premium of approximately 127.0 per cent. to 35.25 pence, being the Closing    
Price per ArmorGroup Share on 26 February 2008, the Business Day prior to       
ArmorGroup's announcement that it was in discussions with a number of parties   
regarding a possible offer for ArmorGroup; and                                  

a premium of approximately 156.8 per cent. to 31.15 pence, being the average    
Closing Price per ArmorGroup Share over the three month period up to and        
including 26 February 2008.                                                     

ArmorGroup's proposed final dividend in respect of the year ended 31 December   
2007 of 1.5 pence per ArmorGroup Share, announced today, is included in the     
Offer Price and hence such final dividend will not be paid if the Offer becomes 
or is declared wholly unconditional.                                            

The Offer is conditional, inter alia, upon acceptance by ArmorGroup Shareholders
who together own 90 per cent. of the ArmorGroup Shares to which the Offer       
relates and not less than 90 per cent. of the voting rights carried by those    
ArmorGroup Shares. The conditions to the Offer are set out in full in Appendix I
to this Announcement.                                                           

The ArmorGroup Shares will be acquired by Bidco fully paid and free from all    
liens, equitable interests, charges and encumbrances and other interests        
whatsoever.                                                                     

3.	Background to and reasons for the Offer                                      

G4S is an international leader in the provision of risk management and          
protection to governments and major corporate customers around the world.  G4S's
management has developed a strategy for accelerated growth and development and  
has communicated to the capital markets that this strategy would involve the    
acquisition of expertise in a number of key areas.  The proposed acquisition of 
ArmorGroup represents an important and logical step in the delivery of the G4S  
strategy.                                                                       

Further Exposure to High Growth Developing Markets - G4S has experience of      
providing risk management and protection to governments and corporate customers 
in a number of high risk environments throughout the Middle East, Africa, Russia
and South America. The acquisition of ArmorGroup extends that experience further
and provides an opportunity to share best practice across a highly specialised  
international workforce in these high growth, high margin markets.              

Customer Relationship Development - G4S has extensive relationships with        
governments and non-government organisations around the world, with particular  
emphasis on the UK and US in the areas of defence, homeland security,           
international development, justice and energy.  The acquisition of ArmorGroup   
will enable G4S to extend those relationships further into additional government
areas and enhance its existing contact base across key government departments.  

Geographic Expansion - G4S has an unrivalled geographic footprint in the        
security solutions sector, with operations in over 110 countries.  The          
acquisition of ArmorGroup provides G4S with market entries into four new        
countries: Sudan; Afghanistan; Algeria; and Rwanda.                             

Market Consolidation - G4S and ArmorGroup each have local operations in the     
following markets:

The acquisition of ArmorGroup will enable the sharing of best practice in these 
regions and potential synergies in administrative and infrastructure costs.     

Additional Specialist Services - ArmorGroup has considerable expertise in key   
niche areas such as mine clearance and disposal, risk management, kidnap for    
ransom and extortion services and training services for the military, law       
enforcement and government agencies.  There are significant opportunities to    
develop these specialist services further and to offer them to G4S's broad      
international customer base.                                                    

Cost Synergies - G4S has identified cost synergies of at least £5 million       
largely through rationalisation of administration functions.                    

General - ArmorGroup is highly complementary to G4S's existing operations and   
G4S believes that there is compelling financial and strategic logic in a        
combination of the respective activities.                                       

4.	Recommendation                                                               

The ArmorGroup Board, which has been so advised by Rothschild, considers the    
terms of the Offer to be fair and reasonable.  In providing its advice,         
Rothschild has taken into account the commercial assessments of the ArmorGroup  
Directors.                                                                      

Accordingly, the ArmorGroup Board intends unanimously to recommend that         
ArmorGroup Shareholders accept the Offer, as the ArmorGroup Directors who hold  
ArmorGroup Shares have themselves irrevocably undertaken to do in respect of    
their own beneficial holdings (and, where applicable, those of their wives)     
totalling, in aggregate, 1,231,049 ArmorGroup Shares, representing approximately
2.30 per cent. of ArmorGroup's existing issued share capital.                   

5.	Background to and reasons for the recommendation                             

The ArmorGroup Board and its advisers have received a number of approaches over 
several months and have engaged in discussions with a number of trade and       
financial parties regarding a range of strategic options for ArmorGroup,        
including possible offers and other business combinations.  On 27 February 2008,
following a movement in ArmorGroup's share price, the ArmorGroup Board was      
obliged, under the Code, to announce that it was in discussions with a number of
parties regarding possible offers for ArmorGroup.                               

On 27 November 2007, ArmorGroup announced that operating profits for the year   
ending 31 December 2007 would be below that reported in the prior year and that 
David Seaton, Chief Executive Officer, would be stepping down with immediate    
effect. Following this, the ArmorGroup Board carried out a review of            
ArmorGroup's business which was completed in early January 2008.  As a result of
this review, the ArmorGroup Board reorganised certain aspects of ArmorGroup's   
operational and administrative structure, as a result of which, the ArmorGroup  
Board remains confident about the future prospects of ArmorGroup.               

The ArmorGroup Board considers, however, that the Offer, at a price of 80 pence 
per ArmorGroup Share in cash, representing a premium of approximately 127.0 per 
cent. to the Closing Price on 26 February 2008, provides ArmorGroup Shareholders
with the prospect of a cash exit at an attractive price when considered against 
the potential of ArmorGroup as a standalone business.                           

6.	Irrevocable undertakings                                                     

All of the ArmorGroup Directors who hold ArmorGroup Shares have irrevocably     
undertaken to accept (or procure the acceptance of) the Offer in respect of     
their own beneficial holdings (and, where applicable, those of their wives),    
representing, in aggregate, approximately 2.30 per cent. of ArmorGroup's        
existing issued share capital.                                                  

In addition, Bidco has received irrevocable undertakings from certain ArmorGroup
Shareholders to accept (or procure the acceptance of) the Offer in respect of   
their beneficial holdings, representing, in aggregate, approximately 50.73 per  
cent. of ArmorGroup's existing issued share capital.                            

Accordingly, Bidco has received, in aggregate, irrevocable undertakings to      
accept the Offer in respect of 28,327,891 ArmorGroup Shares representing        
approximately 53.03 per cent. of ArmorGroup's existing issued share capital.    

Further details of these irrevocable undertakings are set out in Appendix III to
this Announcement.

9.	Financing of the Offer                                                       

Full acceptance of the Offer (assuming the exercise of all outstanding options  
with an exercise price of less than the Offer Price per ArmorGroup Share under  
the ArmorGroup Share Schemes) will result in the payment by Bidco of            
approximately £43.6 million in cash.                                            

The cash consideration payable by Bidco under the terms of the Offer will be    
funded from the existing cash resources of the G4S Group.                       

Greenhill has confirmed that it is satisfied that the necessary financial       
resources are available to Bidco to enable it to satisfy in full the cash       
consideration payable by Bidco as a result of full acceptance of the Offer.     

10.	Management, employees and locations                                         

G4S recognises the skills, technical ability and experience of the existing     
management and employees of ArmorGroup. Accordingly, G4S intends to continue to 
maintain ArmorGroup's strong positions in the markets in which ArmorGroup       
currently operates. There are no immediate plans to change the principal        
operational locations of ArmorGroup's business.                                 

The G4S Directors have given assurances to the ArmorGroup Directors that, if the
Offer becomes or is declared unconditional in all respects, the existing        
employment rights, including pension rights, of all management and employees of 
ArmorGroup will be fully safeguarded.                                           

The ArmorGroup Board welcomes the assurances received from G4S above as they    
are, in the view of the board, in the interests of ArmorGroup and its employees.

The non-executive directors of ArmorGroup intend to resign from the ArmorGroup  
Board shortly after the Offer becomes or is declared unconditional in all       
respects and agree to waive entitlements against ArmorGroup except for payments 
in lieu of notice and other payments and benefits to which they are entitled    
under the terms of their letters of appointment.                                

11.	ArmorGroup Share Schemes                                                    

The Offer will extend to any ArmorGroup Shares issued or unconditionally        
allotted or issued fully paid (or credited as fully paid) whilst the Offer      
remains open for acceptance (or until such earlier date as, subject to the City 
Code, Bidco may decide, being not earlier than the date on which the Offer      
becomes or is declared unconditional as to acceptances, or if later, the final  
closing date of the Offer), including those allotted or issued as a result of   
the exercise of options or vesting of awards under the ArmorGroup Share Schemes.

Bidco intends to make appropriate proposals to the holders of options and awards
under the ArmorGroup Share Schemes upon the Offer becoming or being declared    
unconditional in all respects, to the extent that such options and awards have  
not been exercised or vested by that date.                                      

12.	Inducement Fee Agreement and Non-Solicitation Agreement                     

ArmorGroup has agreed, pursuant to an inducement fee agreement, to pay to Bidco 
a fee of a sum equivalent to 1 per cent. of the aggregate Offer Price plus any  
VAT chargeable in respect of the fee to the extent recoverable if:              

the ArmorGroup Board withdraws or adversely modifies its recommendation and the 
Offer subsequently lapses or is withdrawn solely due to non-satisfaction of any 
condition other than that set out in paragraph 1(b) of Appendix I to this       
Announcement; or                                                                

prior to the Offer being withdrawn or lapsing a competing offer, scheme of      
arrangement or other similar transaction relating to ArmorGroup is announced and
subsequently becomes unconditional in all respects or is completed or           
implemented.                                                                    

The inducement fee shall not be payable if the Offer lapses or is withdrawn due 
to non-satisfaction of the condition set out in paragraph 1(b) of Appendix I to 
this Announcement.                                                              

Subject to any obligations of confidentiality, if the ArmorGroup Directors      
determine that any competing offer proposal received by them constitutes an     
offer proposal for ArmorGroup which the ArmorGroup Board is minded to recommend 
(a Superior Proposal), ArmorGroup shall use all reasonable endeavours to notify 
Bidco of such Superior Proposal (such notification to include, subject to       
compliance by the ArmorGroup Directors with any obligations of confidentiality  
and with their fiduciary and other obligations as directors, confirmation of the
price and form of consideration offered under such Superior Proposal and the    
identity of the proposed offeror in respect of such Superior Proposal).  Such   
notification must be made as soon as reasonably practicable and, in any event,  
within 12 hours after making a determination that such competing offer proposal 
constitutes a Superior Proposal.                                                

Pursuant to Rule 21.2 of the City Code, Rothschild and ArmorGroup have confirmed
to the Panel that they consider the agreement to pay the inducement fee to be in
the best interests of ArmorGroup Shareholders.                                  

ArmorGroup has also entered into a non-solicitation agreement with Bidco (the   
Non-Solicitation Agreement), which, subject to the Offer Document being posted  
to ArmorGroup Shareholders within 28 days of this Announcement (or such later   
date as the Panel may allow), will, in broad terms, remain in force from the    
date of the Announcement until the earlier of the Offer becoming or being       
declared unconditional in all respects and the Offer lapsing.                   

Under the terms of the Non-Solicitation Agreement, ArmorGroup may not, except as
stated below:                                                                   

solicit, initiate or encourage (directly or indirectly) enquiries or proposals  
from any third party in respect of, or in connection with, an offer for         
ArmorGroup or an acquisition or purchase of all or a substantial portion of the 
assets of, or of a substantial equity interest in, or any business combination  
or share exchange with ArmorGroup or any of its subsidiary undertakings (a      
Relevant Acquisition);                                                          

enter into or participate in any discussions relating to any possible Relevant  
Acquisition; or                                                                 

provide any information to any third party in connection with a Relevant        
Acquisition.                                                                    

The terms of the Non-Solicitation Agreement would not prevent the ArmorGroup    
Directors from:                                                                 

complying with the provisions of Rule 20.2 of the City Code; or                 

responding to or entering into and pursuing discussions in respect of an        
unsolicited approach or indication of interest relating to a Relevant           
Acquisition received after the date of the Non-Solicitation Agreement if the    
fiduciary and other duties of the ArmorGroup Directors so require.              

The Non-Solicitation Agreement obliges ArmorGroup:                              

to notify Bidco if it is approached by any third party in connection with a     
Relevant Acquisition (subject to any obligation of confidentiality imposed      
unilaterally by such third party) or if ArmorGroup provides information to any  
such third party pursuant to Rule 20.2 of the City Code; and                    

save to the extent that the fiduciary and other duties of the ArmorGroup        
Directors require otherwise: (a) only to give information relating to ArmorGroup
to the extent that ArmorGroup is strictly obliged to provide the third party    
with it pursuant to Rule 20.2 of the Code; and (b) provide a list of any such   
information so provided to Bidco. Any such information may only be made         
available on terms that are equivalent in all material respects to those        
contained in a confidentiality agreement entered into between ArmorGroup and    
Bidco (subject to compliance with Note 2 on Rule 21.2 of the Code).             

The Non-Solicitation Agreement also states that ArmorGroup will not be obliged  
to pay any amount to the extent to which the Panel determines it would not be   
permitted to do so by Rule 21.2 of the Code.                                    

13.	De-listing and compulsory acquisition                                       

If Bidco receives acceptances under the Offer in respect of, and/or otherwise   
acquires 90 per cent. or more in value of the ArmorGroup Shares to which the    
Offer relates (and not less than 90 per cent. of the voting rights carried by   
ArmorGroup Shares), and if all other conditions of the Offer have been satisfied
or waived (to the extent that they are capable of being waived), Bidco intends  
to exercise its rights pursuant to the provisions of Part 28 of the Companies   
Act 2006 to acquire compulsorily any remaining ArmorGroup Shares in respect of  
which acceptances have not then been received on the same terms as the Offer.   

If the Offer becomes or is declared unconditional in all respects, and          
sufficient acceptances under the Offer are received and subject to any          
applicable requirements of the UK Listing Authority, Bidco intends to procure   
that ArmorGroup makes applications to cancel the listing of ArmorGroup Shares on
the Official List and to cancel admission to trading in ArmorGroup Shares on the
London Stock Exchange's market for listed securities. De-listing would          
significantly reduce the liquidity and marketability of any ArmorGroup Shares   
not assented to the Offer at that time and the value of any such ArmorGroup     
Shares may be affected as a consequence.                                        

It is anticipated that cancellation of the listing on the Official List and of  
admission to trading on the London Stock Exchange's market for listed securities
will take effect no earlier than 20 Business Days after the earlier of (i) the  
date on which Bidco has, by virtue of its shareholdings and acceptances of the  
Offer, acquired or agreed to acquire issued share capital carrying 75 per cent. 
of the voting rights of ArmorGroup and (ii) the first date of issue of          
compulsory acquisition notices under Chapter 3 Part 28 of the Companies Act     
2006. Bidco will notify ArmorGroup Shareholders when the required threshold has 
been attained and confirm that the notice period has commenced and the          
anticipated date of cancellation.                                               

It is also intended that, following the Offer becoming or being declared        
unconditional in all respects and after the de-listing and cancellation referred
to above becoming effective, ArmorGroup will be re-registered as a private      
company under the relevant provisions of the Act.                               

14.	Disclosure of interests in ArmorGroup Shares                                

Save for the irrevocable undertakings referred to in paragraph 6 above, neither 
G4S nor Bidco nor any of their respective directors nor, so far as the directors
of G4S and Bidco are aware (having made due and careful enquiry), any person    
acting, or deemed to be acting, in concert with G4S and/or Bidco for the        
purposes of the Offer, owns or controls or holds any option to purchase, or has 
any arrangement in relation to ArmorGroup Shares or securities convertible or   
exchangeable into ArmorGroup Shares or options (including traded options) in    
respect of, or has entered into any derivative referenced to, any such shares or
has had any short positions (whether conditional or absolute and whether in the 
money or otherwise) in ArmorGroup Shares or has borrowed or lent any ArmorGroup 
Shares (except for any borrowed shares which have been either on-lent or sold). 

For these purposes, "arrangement" includes any indemnity or option arrangement, 
any agreement or understanding, formal or informal, of whatever nature, relating
to ArmorGroup Shares which may be an inducement to deal or refrain from dealing 
in such shares.                                                                 

15.	Overseas Shareholders                                                       

Unless otherwise determined by Bidco, the Offer will not be made, directly or   
indirectly, in or into any Restricted Jurisdiction and the Offer will not be    
capable of acceptance from or within any Restricted Jurisdiction. Accordingly,  
copies of this Announcement are not being and must not be, directly or          
indirectly, mailed or otherwise forwarded, distributed or sent in, into or from 
any Restricted Jurisdiction and persons receiving this Announcement (including  
custodians, nominees and trustees) must not mail or otherwise distribute or send
it in, into or from such jurisdictions as doing so may invalidate any purported 
acceptance of the Offer.                                                        

It is the responsibility of such Overseas Shareholders to inform themselves     
about and observe any applicable legal requirements. No person receiving a copy 
of the Offer Document and/or a Form of Acceptance in any jurisdiction other than
the UK may treat the same as constituting an invitation or offer to him, nor    
should he in any event use such Form of Acceptance, if, in the relevant         
jurisdiction, such invitation or offer cannot lawfully be made to him or such   
Form of Acceptance cannot lawfully be used without contravention of any relevant
or other legal requirements. In such circumstances, the Offer Document and/or   
Form of Acceptance are sent for information only. It is the responsibility of   
any Overseas Shareholder receiving a copy of the Offer Document and/or Form of  
Acceptance and wishing to accept the Offer to satisfy himself as to the full    
observance of the laws and regulatory requirements of the relevant jurisdiction 
in connection with the Offer, including obtaining any governmental, exchange    
control or other consents which may be required, and compliance with other      
necessary formalities needing to be observed and payment of any issue, transfer 
or other taxes or duties due in such jurisdiction.                              

16.	General                                                                     

The Offer Document will be sent to ArmorGroup Shareholders and, for information 
only, to participants in the ArmorGroup Share Schemes, as soon as is reasonably 
practicable.                                                                    

The Offer will be subject to the conditions set out in Appendix I. The bases and
sources of certain financial information contained in this Announcement are set 
out in Appendix II. Further details of the irrevocable undertakings referred to 
in paragraph 6 above are set out in Appendix III. Certain terms used in this    
Announcement are defined in Appendix IV to this Announcement.                   

The Acquisition is proposed to be implemented by way of the Offer. However,     
Bidco reserves the right to implement the Offer by way of a scheme of           
arrangement of ArmorGroup pursuant to section 425 of the Companies Act 1985 or  
the successor provision under Companies Act 2006. In such event, the scheme of  
arrangement will be implemented on the same terms, so far as applicable, as     
those which would apply to the Offer (subject to appropriate amendments).  In   
particular, condition 1(a) of the conditions would not apply and the scheme of  
arrangement would become effective and binding following:                       

approval of the scheme of arrangement at a meeting convened by the Court by a   
majority in number, representing 75 per cent. or more in value, present and     
voting, either in person or by proxy, of ArmorGroup Shareholders (or the        
relevant class or classes thereof);                                             

the resolution(s) required to implement the scheme of arrangement being passed  
by the requisite majority of ArmorGroup Shareholders at a general meeting of    
ArmorGroup validly convened for such purpose; and                               

sanction of the scheme of arrangement and confirmation of any reduction of      
ArmorGroup's share capital involved therein by the Court (in both cases, with or
without modifications, on terms reasonably acceptable to Bidco) and office      
copies of the orders of the Court sanctioning the scheme of arrangement and     
confirming the reduction of share capital being delivered for registration to   
the Registrar of Companies in England and Wales and being registered by him.

and possessions, any state of the United States and the District of Columbia).  
The securities referred to herein have not been and will not be registered under

The availability of the Offer to ArmorGroup Shareholders who are citizens or    
residents of jurisdictions outside the United Kingdom may be affected by the    
laws of their relevant jurisdiction. Such persons should inform themselves of,  
and observe, any applicable legal or regulatory requirements of their

adviser in the relevant jurisdiction without delay.                             

Any acceptance or other response to the Offer should be made only on the basis  
of information referred to in the Offer Document which Bidco intends to despatch
as soon as is reasonably practicable to ArmorGroup Shareholders and, for        
information only, to participants in the ArmorGroup Share Schemes.              

The G4S Directors and the Bidco Directors accept responsibility for the         
information contained in the above summary and this Announcement other than     
information relating to the ArmorGroup Group, the ArmorGroup Directors and their
immediate families, related trusts and controlled companies. To the best of the 
knowledge and belief of the G4S Directors and the Bidco Directors (who have     
taken all reasonable care to ensure that such is the case), the information     
contained in this summary and the attached Announcement for which they accept   
responsibility is in accordance with the facts and does not omit anything likely
to affect the import of such information.                                       

The ArmorGroup Directors accept responsibility for the information in the above 
summary and this Announcement relating to them and their immediate families,    
related trusts and controlled companies and the ArmorGroup Group.               

This Announcement has been prepared for the purposes of complying with English  
law, the City Code and the Listing Rules and information disclosed may not be   
the same as that which would have been disclosed if this Announcement had been  
prepared in accordance with the laws of jurisdictions outside                   
England.                                                                        

The Offer will be subject to the applicable rules and regulations of the        
Financial Services Authority, the London Stock Exchange and the City Code.      

Dealing Disclosure Requirements                                                 

Under the provisions of Rule 8.3 of the Code, if any person is, or becomes,     
"interested" (directly or indirectly) in 1% or more of any class of "relevant   
securities" of ArmorGroup, all "dealings" in any "relevant securities" of that  
company (including by means of an option in respect of, or a derivative         
referenced to, any such "relevant securities") must be publicly disclosed by no 
later than 3.30 p.m. (London time) on the Business Day following the date of the
relevant transaction. This requirement will continue until the date on which the
Offer becomes, or is declared, unconditional as to acceptances or is otherwise  
withdrawn or on which the "offer period" otherwise ends. If two or more persons 
act together pursuant to an agreement or understanding, whether formal or       
informal, to acquire an "interest" in "relevant securities" of ArmorGroup, they 
will be deemed to be a single person for the purpose of Rule 8.3.               

Under the provisions of Rule 8.1 of the Code, all "dealings" in "relevant       
securities" of ArmorGroup by Bidco, G4S or ArmorGroup, or by any of their       
respective "associates", must be disclosed by no later than 12.00 noon (London  
time) on the Business Day following the date of the relevant transaction.       

A disclosure table, giving details of the companies in whose "relevant          
securities" "dealings" should be disclosed, and the number of such securities in
issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.      

"Interests in securities" arise, in summary, when a person has long economic    
exposure, whether conditional or absolute, to changes in price of securities. In
particular, a person will be treated as having an "interest" by virtue of the   
ownership or control of securities, or by virtue of any option in respect of, or
derivative referenced to, securities.                                           

Terms in quotation marks are defined in the Code, which can also be found on the
Panel's website. If you are in any doubt as to whether or not you are required

becomes or is declared unconditional as to acceptances, whether pursuant to the 
exercise of conversion or subscription rights or otherwise and for the purposes 
of this condition:

in accordance with sections 974 to 991 Companies Act 2006;

acceptances of the Offer;

obtained either unconditionally or subject to such conditions, obligations,     
undertakings or modifications as shall be acceptable to Bidco, acting           
reasonably;  and                                                                
all applicable mandatory waiting periods in connection with any such filings,   
submissions or notifications having expired or been terminated.

satisfactory to Bidco from all appropriate Third Parties or persons with whom   
any member of the Wider ArmorGroup Group has entered into any material          
contractual arrangements and all such Authorisations, together with all

any material respect or not to grant or review any of the same where the

the absence of such filings or applications, the appropriate waiting period in  
respect of the Offer not having expired, lapsed or been terminated or the

before the Announcement Date by disclosure publicly by an announcement to a

For the purposes of these conditions:                                           

Disclosed means fairly disclosed to Bidco and/or G4S and/or their respective    
directors and/or advisers prior to the Announcement Date either: by inclusion in
the Announcement, inclusion in the annual report and accounts of ArmorGroup for 
the financial year ended 31 December 2006 or inclusion in the unaudited accounts
of ArmorGroup for the six months ended 30 June 2007, by delivery of announcement
by or on behalf of ArmorGroup to a Regulatory Information Service (including,   
for the avoidance of doubt, the preliminary results of ArmorGroup for the       
financial year ended 31 December 2007 announced today) or otherwise in writing; 

Wider ArmorGroup Group means ArmorGroup and its subsidiary undertakings,        
associated undertakings and any other undertaking in which ArmorGroup and/or    
such undertakings (aggregating their interests) have a significant interest;    

Wider G4S Group means G4S and its subsidiary undertakings, associated           
undertakings and any other undertaking in which G4S and/or such undertakings    
(aggregating their interests) have a significant interest;                      

subsidiary undertaking, associated undertaking and undertaking have the meanings
given by the Companies Act 1985, other than paragraph 20(1)(b) of Schedule 4A to
that Act which shall be excluded for this purpose; and                          

significant interest means a direct or indirect interest in more than 20 per    
cent. of the equity share capital (as defined in that Act).                     

Bidco reserves the right to waive, in whole or in part, all or any of conditions
b to j inclusive.  Conditions b to j must be satisfied as at, or waived on or   
before midnight (London time), on the twenty first day after the later of the   
First Closing Date and the date on which condition a is fulfilled (or in each   
case such later date as the Panel may agree).                                   
Bidco shall be under no obligation to waive (if capable of waiver) or treat as  
fulfilled any of conditions b to j inclusive by a date earlier than the latest  
date specified above for the fulfilment thereof, notwithstanding that the other 
conditions of the Offer may at such earlier date have been fulfilled and that   
there are, at such earlier date, no circumstances indicating that any of such   
conditions may be incapable of fulfilment.                                      
If Bidco is required by the Panel to make an offer for ArmorGroup Shares under  
the provisions of Rule 9 of the Code, Bidco may make such alterations to the    
above conditions of the Offer, including condition (a), as are necessary to     
comply with the provisions of that Rule.                                        
The Offer will lapse if it is referred to the Competition Commission before 1.00
p.m. (London time) on the First Closing Date or the time and date on which the  
Offer becomes or is declared unconditional as to acceptances, whichever is the  
later. In such circumstances, the Offer will cease to be capable of further     
acceptance and persons accepting the Offer and Bidco shall thereupon cease to be
bound by acceptances of the Offer made or delivered on or before the date on    
which the Offer so lapses.                                                      
Under Rule 13.4 of the Code, an offeror should not invoke any condition or      
pre-condition of an offer so as to cause the offer not to proceed, to lapse or  
to be withdrawn unless the circumstances which give rise to the right to invoke 
the condition or pre-condition are of material significance to the offer or in  
the context of the offer. The acceptance condition is not subject to Rule 13.4. 
The ArmorGroup Shares will be acquired by Bidco fully-paid up and free from all 
liens, equitable interests, charges, encumbrances, rights of pre-emption, and   
other third party rights or interests of any nature whatsoever and together with
all rights now or hereafter attaching thereto, including the right to receive   
and retain all dividends and other distributions (if any) declared, made or paid
on or after the date on which the Offer is made.
