HOUSTON, TX -- (MARKET WIRE) -- October 17, 2006 -- AT&T Inc. (NYSE: T) today announced a new contract with MergerTree Solutions, LP, a technology managed services provider with headquarters in Houston, Texas. Under the terms of the three-year contract, AT&T will serve as the primary provider, delivering a complete package of IT services consisting of AT&T's network-based Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) along with Managed Internet Service (MIS) to all MergerTree locations across the region, as well as AT&T Enterprise Hosting services at an off-site AT&T Internet Data Center (IDC).

AT&T network-based MPLS VPN provides a robust and flexible network infrastructure, allowing unified communications among regional locations. The service will deliver increased bandwidth and redundancy to MergerTree Solutions' fully meshed MPLS network. AT&T Enterprise Hosting services deliver an always-on data center infrastructure with advanced power, network and security features backed by industry leading service-level agreements.

The MIS will support dedicated and consistent Internet and network access.

The converged AT&T solution will allow secure and reliable user access to MergerTree's business-critical hosted IT infrastructure and provide a cost-effective external communications solution. The upgraded bandwidth, coupled with data center hosting services in the AT&T IDC, will provide a solid foundation for MergerTree Solutions to increase its Intranet security while helping to support the company's critical applications for business continuity.
