Enclosure:  Re Contract


Copy of announcement regarding Re Contract sent to the London Stock Exchange
on 19 July 2005


                O2 AIRWAVE WINS AMBULANCE COMMUNICATIONS CONTRACT

Released: 19 July 2005

O2 Airwave today  announced that it has been  successful in its bid to provide a
communications  service to all Ambulance  Trusts in England.  The total value of
the contract for network  access and the provision and  integration of equipment
is  approximately  GBP390  million over 13 years.  When the system is installed,
patients  will benefit from  reliable  voice and data services that will enhance
the scope of care delivery by paramedics at incident  scenes and help to improve
ambulance response times.

The  Scottish  Ambulance  Service  and the  Welsh  Ambulance  Service  Trust are
scheduled to make a decision on the choice of their new communications  solution
in the near future.

Airwave,  the national  digital radio  communications  network  dedicated to the
emergency  services,  has already been rolled out to all 51 geographical  police
forces in England,  Scotland and Wales.  O2 Airwave is also  shortlisted for the
Fire Service national contract.  If all the mainland Ambulance and Fire services
subsequently  adopt the  Airwave  service,  they will join an  existing  150,000
Police users. With 78 other Public Safety related  organisations  already signed
up to the service,  the potential  number of UK users is now well in excess of a
quarter of a million.

The new communications  solution for the English Ambulance Trusts will give them
up-to-date digital,  secure and crystal-clear voice calls. Airwave also makes it
possible to deliver a wide range of highly resilient and secure data services to
front-line   ambulances.   In  addition  to   emergency   and  routine   private
communications,  paramedics  and  control  room  operators  will be able to talk
directly  with  police  at the  scene of an  incident  when it is  operationally
beneficial.

The Health Minister,  Lord Warner,  stated:  "This new digital service will help
deliver  better  patient  care  by  enabling   ambulances  to  communicate  more
effectively,  improve  interfaces  with hospitals and increase  interoperability
with the wider NHS.

"The  service  will  provide  a faster,  more  reliable  service -  facilitating
improved safety and support for NHS staff, increase security and enable a better
response to major incidents through improved response time and  interoperability
between emergency services."

O2 Airwave and SunGard  Vivista  will  provide a range of products  and services
under the contract.  These include  supplying  radio terminals to paramedics and
ambulance staff,  migrating existing mobile data applications to work on the new
digital network as well as providing Integrated  Communications  Control Systems
(ICCS) for all dispatch centres.

Pete  Richardson,  managing  director of O2  Airwave,  said:  "We are  extremely
pleased to welcome NHS Ambulance Trusts to Airwave and look forward to deploying
the  technology  to the  benefit  of  patients  and  staff.  Airwave is the only
comprehensive  communications service designed in Great Britain specifically for
the  emergency  services  and  public  safety  agencies.  Now  that it is  fully
available across the country, we are receiving interest from a growing number of
organisations that need reliable and flexible communications."

In  addition  to the  emergency  services,  Airwave  is  available  to over  120
organisations  with a public  safety role and already being used by the MOD, the
Highways Agency and several County Councils.

Notes to Editors:

Improved response times and patient care

The new digital  technology  will  enable  services  to improve  response  times
through  status  messaging,   alert  paging,   resource/incident   location  and
mobilisation  messaging.  In an  emergency  the call centre  needs to be able to
access  information  as quickly  as  possible.  The  digital  network  will feed
on-board  equipment with the incident location  co-ordinates,  details about the
patient, nature of the incident and other free text information. A reliable data
service reduces errors and the need to re-transmit  information over noisy radio
channels.

The digital radio communications network is planned to help improve patient care
by allowing  the  paramedic  to transmit an  emergency  patient  health  record,
including, where appropriate, patient vital signs and electrocardiogram rhythms,
ahead to the receiving hospital. It should also allow direct access to a variety
of databases such as patient care protocols, bed status or A&E capacity.

Proven Benefits for Ambulance Trusts and Patients

Airwave has already proven valuable in improving  patient care at the Hereford &
Worcester  Ambulance Service NHS Trust and the Mersey Regional Ambulance Service
by putting  paramedics  and  hospital  consultants  directly  in touch with each
other.  In Hereford & Worcester,  a patient's  vital signs can be transmitted in
real time from an ambulance  enabling  consultants and hospital staff to analyse
them and to authorise paramedics to administer  life-saving  thrombolysing drugs
to heart  attack  patients.  Over 150  patients  have now  benefited  from  this
technology  - most are treated  within the 'golden  hour' and, in one  instance,
paramedics were able to administer  drugs to a patient within 16 minutes of them
calling for an  ambulance.  Services such as these will be possible in all areas
where the Airwave system is in operation.

Chief Executive of Hereford and Worcester Ambulance Service NHS Trust, Russell B
Hamilton,  commented: "I am very pleased to reach this landmark. Our use of this
technology puts Hereford and Worcester  Ambulance Service at the leading edge of
pre-hospital  care in the country.  All those living and working  within the two
counties can have the utmost confidence in the care we provide."

Key Features of Airwave

Airwave is a  sophisticated  communications  system for the  emergency and other
public  safety  ('blue  light')  services.  It will help make  Britain  safer by
facilitating  more  effective  and  efficient  ways of working for the emergency
services, and the opportunity for more 'joined up' public safety services.

     -    For the first time ever,  emergency  services can have radio  coverage
          whenever and wherever they need it - even in radio 'cold spots'.

     -    Airwave  will  enable  emergency  services to  communicate  seamlessly
          regardless of location for the first time ever

     -    Because  all  Airwave  communications  are  encrypted,  they cannot be
          scanned or monitored by outsiders. The network is highly resilient

     -    The system  enables both voice and data  communications  and gives the
          emergency services wide flexibility in choosing how to communicate.
