AT&T Wins Networking Contract from TransUnion

Chicago, Illinois, May 9, 2007

AT&T Inc. (NYSE: T) announced today that TransUnion, a global leader in credit and information management, has selected AT&T to provide a networking solution integrating more than 150 locations in the United States and Canada.

Under the terms of the three-year, $11.4 million agreement, AT&T will deploy Virtual Private Network (VPN) services integrating TransUnion locations with a full range of voice, data, Internet and business-continuity services.

The network services, based on Multiprotocol Label Switching (MPLS) technology, are expected to accelerate day-to-day business transactions in an information-intensive business. TransUnion is a worldwide credit-reporting company serving both consumers and businesses by gathering, analyzing and delivering vast amounts of credit reporting data.

The AT&T solution provides the company with standardized networking services with increased bandwidth and secure, high-speed access to proprietary applications, company databases, e-mail and other operational functions.

The increased bandwidth and speed of the new services enables TransUnion to economically and efficiently support the secure exchange of financial data and a host of other mission-critical applications.

The MPLS solution will serve as a foundation for TransUnion's evolution to a converged multi-service networking platform, enabling deployment of Voice over Internet Protocol (VoIP) and other converged services in the future. The solution also supports the company's business-continuity plan by providing automatic backup and rerouting to another facility in the event of a network disruption or disaster.

"In our information-intensive business, network reliability, speed and security are vital," said Doug Lienberger, vice president-Information Technology, TransUnion. "AT&T has a proven track record for customer service, advanced networking technology, reliability and security that fit our needs like a glove."

TransUnion can monitor the performance of its network services and applications through the secure AT&T customer portal, AT&T BusinessDirect´âó, which provides operational efficiencies including around-the-clock online access to real-time reports on network performance and direct connection to trouble-management systems.
