BOSTON, March 23, 2010 - CallerXchange, the world's leading social address book solution,
repeatedly exceeds performance expectations at Orange. Continuing with their
tradition of launching innovative services, Orange Dominicana was the first
mobile operator in the world to launch the CallerXchange service in 2007.
Since then, the service has since been launched within seven of the world's
largest mobile operator groups across four continents, and is currently
shipping to over 60 million subscribers.

network and CallerXchange has proven to provide value across all subscriber
segments given the consistently high uptake rate."
