Cable&Wireless Worldwide Extends its Relationship With Aviva

LONDON, May 24, 2011 -

    - Leading Global Insurance Provider Selects Cable&Wireless
      Worldwide to Provide Data Services in Europe



    - Contract to Consolidate Communications Across its European
      Countries

Aviva Europe, a leading insurer in the region, has selected
Cable&Wireless Worldwide to provide a fully managed communications backbone
across its European markets. The initial three year contract is the first
step towards a single converged voice and data network across the continent
as part of Aviva's European transformation programme.

The decision to move to one infrastructure provider underpins
Aviva Europe's strategy, designed to transform the company into one truly
effective pan-European business.

Aviva Europe's previous network was delivered by several
service providers and C&W Worldwide was selected as its partner of choice for
the consolidation following a competitive tender. C&W Worldwide currently
provides a fully managed communications solution to Aviva in the UK and
globally.

Philippe Gibert, Technology and IT Infrastructure Director
Aviva Europe, explains: "This converged network is a vital component to our
European transformation programme. The fast, resilient and secure services
provided by C&W Worldwide will be fundamental for our future development."

Jim Marsh, Chief Executive Officer at C&W Worldwide, comments:
"This contract is a clear example of how we can help our current customers
optimise their communications internationally and is a natural extension of
our present relationship. We are excited to have been chosen by Aviva Europe
to help them realise their vision. By consolidating Aviva Europe's networks,
we will not only help them realise better efficiencies but also ensure that
they will be freed up to focus their attention and resources on encouraging
growth."
