Enclosures:  1.  Acquisition announcement made on 16 September, 2004




16 September 2004

BT AGREES TO BUY B.I.C. SYSTEMS GROUP LTD TO PROVIDE UNIQUE IT AND NETWORKING
SERVICES

BT through its business in Northern Ireland has agreed to buy B.I.C. Systems
Group Ltd for a cash consideration of GBP17 million.
This will accelerate BT to the forefront of the IT and networking services
sector in Northern Ireland two years ahead of schedule in its planned five year
strategic programme.

Describing the purchase as 'one of the most exciting developments in the IT
space in years', Bill Murphy, Managing Director, BT Regions heralded the move as
being good for Northern Ireland, good for BT and good for B.I.C. Systems Group
Ltd.

"This is a unique and exciting development for both companies, " he said.
"I believe the acquisition will create a company of incomparable experience at
a time when Northern Ireland's IT future looks bright and when IT skills have
never been more essential."

"The joint capabilities of both organisations will offer exciting opportunities
for business and operations throughout the island both for the public and
private sectors."

"We are delighted to be joining with a company as innovative as B.I.C. Systems
Group Ltd. This is a company which, guided by Ed Vernon and his colleagues, has
become one of the most significant players in the IT market place."

"We believe that our joint expertise will lift the level of ICT services
provision in Northern Ireland to new heights and together we can provide unique
solutions at exceptional value for money for both the public and private
sectors."

Ed Vernon, chief executive of B.I.C. Systems Ltd said, "This is a great
development for us and for Northern Ireland."

"The international IT market place is a tough and competitive environment. In
agreeing to sell to BT we will create a new ICT company capable of delivering
real shareholder value and excellent and innovative products and services to our
customers."

"BT Northern Ireland brings superb skills and expertise to this combination.
Together we will raise the ICT level in Northern Ireland and that can only be
good for the public and private sectors."

Alastair Hamilton, director of BT Business at BT Northern Ireland said, "I'm
very excited about the potential arising from these synergies and look forward
to delivering on these to the public and private sectors here in Northern
Ireland and further afield. We are very much on track in our stated aim of
offering outstanding IT and networking services."

Neither brand will change. Both B.I.C.Systems Group Ltd and the BT brands are
well recognised, well established in the marketplace and each holds value in
its own right. Both brands will be enhanced through association with each other
and by capitalising on the individual and distinct strengths of each.
BT directly employs almost 3,000 people in Northern Ireland. There will be no
job losses. This acquisition is further evidence of BT's commitment to Northern
Ireland. It also means that local businesses and public sector organisations
will now have a local company with the skills and capability to deliver
sustainable and effective end-to-end solutions. This acquisition (which is
conditional on regulatory approval) will create a formidable ICT force with a
depth of capability which will add to the attraction of Northern Ireland as a
location in which to do business.
