BP Awards Global Communications Contract to T-Systems in Landmark Agreement

LONDON, December 2 - T-Systems, the business solutions arm of Deutsche Telekom, has secured a
landmark contract to provide telecommunications services to global energy
group, BP plc.

The five year contract will play a key role in supporting BP's ongoing
efficiency programme by delivering significant cost savings.

T-Systems will transform BP's global telecoms services network enabling
it for next generation voice and data services. In a flexible contract, BP's
business units will have the freedom to choose communications services that
align with their specific needs and cost base.

The agreement heralds the introduction of a new multi-sourcing model for
communications services. The transformation programme will simplify BP's
existing network, heavily reducing the number of suppliers to remove
complexity, significantly lowering the cost of operations and ensuring end to
end service quality.

In a parallel agreement, Siemens Enterprise Communications (SEN Group)
will be providing a global managed service that supports BP's voice
requirements, including managed telephone and audio visual services. The two
companies have extensive experience of working together and enjoy a strong
track record of successful collaboration.

Dana Deasy, BP Group CIO, said: "We are looking forward to working with
our new strategic partner for BP's telecoms services. Their expertise, new
perspective and energy will give BP a significant opportunity to reduce
complexity and lower our overall cost base."

"We are proud to have become a key partner for change at BP", said
Reinhard Clemens, CEO, T-Systems. "In the current economic climate, it is
imperative that ICT providers demonstrate a clear ability to have a positive
impact on their clients' business performance. From today, it will be a
priority for T-Systems to apply our combination of IT and Telecommunications
capabilities to deliver strong business results for BP."

Today's announcement underlines T-Systems' continued progress in
achieving its goal of becoming the leading ICT provider for global
corporations and public institutions.
