Citizens Republic Bancorp Extends Multimillion-Dollar Voice and Data Networking Deal with AT&T

Michigan's Largest Bank Holding Company to Control Costs by Streamlining Traffic Onto a Single Set of Optimized Network Services

Flint, Michigan, April 15, 2008

AT&T Inc. (NYSE:T) has announced that Citizens Republic Bancorp has extended its contract with AT&T for network and conferencing services for the next five years. The multimillion-dollar agreement will enable AT&T to merge all of the financial company's locations onto a single Internet Protocol (IP)-based platform, which will enhance network efficiency and control voice and data service costs.

With nearly 250 locations, which offer a wide set of financial services, throughout Michigan, Ohio, Wisconsin and Iowa, Citizens Republic Bancorp is one of the leading financial services companies in the United States. AT&T will migrate all Citizens locations onto AT&T's Multiprotocol Label Switching (MPLS)-backed network. The new network services will create a single connection for all the Citizens locations that are fully managed and maintained by AT&T. The services will also provide optimized network performance while positioning Citizens for future advanced voice and video-transmission technology.

"AT&T's solution allows us to serve our clients with the efficiency and ease of one of the most reliable networks while controlling our voice and data service costs," said Jerry Bettens, chief information officer, Citizens Republic Bancorp.

To further secure its newly integrated network services, Citizens Republic Bancorp purchased AT&T's SONET Ring service. As a leader in business-continuity planning, Citizens Republic Bancorp will protect its critical financial information with AT&T's SONET Ring architecture, which creates a redundant circular network cycle and is monitored around-the-clock by AT&T specialists.
