Syniverse to Acquire BSG's Wireless Clearing and Financial Settlement Business

Syniverse Technologies (NYSE: SVR), a leading provider of
mission-critical technology services to wireless telecommunications
companies worldwide, announced today that it has signed a definitive
agreement to acquire the wireless clearing and financial settlement
business of Billing Services Group (LSE: BILL), a leading global
provider of clearing, settlement, payment and financial risk
management solutions for communications service providers, for
approximately $290 million in cash (which includes debt to be
refinanced at closing).

The proposed acquisition will combine Syniverse's industry-leading
technology interoperability and network services capabilities with
BSG's strong GSM data clearing expertise; excellent European, Middle
Eastern and Asian operator relationships; and leading financial
clearing and settlement capabilities. BSG serves approximately 180
mobile operators globally.

"The proposed acquisition of BSG's Wireless business will allow us
to better serve the demands of our clients; further develop our global
operations and customer base in Europe, Asia and the Middle East; and
allow us to continue to be a leading service provider to GSM operators
worldwide," said Tony Holcombe, President and CEO of Syniverse. "The
acquisition also brings to Syniverse a number of new services,
including a best-in-class financial clearing platform, several new
wireless services and additional product development expertise that
will position us to better serve the increasingly complex needs of our
global wireless customers."

"This proposed acquisition brings together two companies with very
complementary skill sets," said Atul Devani, CEO of BSG Wireless. "BSG
has a state-of-the-art, flexible and efficient clearing platform that
scales well to meet the growing demands of GSM operators globally.
Together with Syniverse's strong GSM technical abilities, emphasis on
delivering outstanding customer support and broad suite of services,
the combined organization will be a premier services provider to
mobile operators worldwide."

The transaction is subject to customary closing conditions,
including BSG shareholder approval and regulatory approvals, and is
expected to close as soon as such approvals are obtained. Syniverse
expects the transaction to be accretive to adjusted net income and
cash net income in 2007, and anticipates providing updated financial
guidance following the closing.

Following completion of the transaction and integration of the two
businesses, Syniverse intends to maintain its European headquarters in
The Netherlands and its European operations in BSG's facilities in
Germany and the United Kingdom.

Committed financing is being provided by Lehman Brothers in
conjunction with Deutsche Bank and Bear, Stearns & Co. In addition,
Deutsche Bank and Bear, Stearns & Co. served as strategic advisors to
Syniverse on the transaction. Kirkland and Ellis LLP and Ernst & Young
also advised on the transaction.
