CHICAGO -- AT&T today announced it has been awarded a three-year contract from Chicago Mercantile Exchange Inc. (CME), the leading futures exchange in the United States, for a fully managed hosting solution to support CME's www.cme.com Web site. Terms of the contract were not disclosed.

The site, located in AT&T's Chicago-area Internet Data Center, hosts applications that enable thousands of traders, brokers and market analysts around the world to access real-time quotes, research historical trading data and obtain corporate information.

Under terms of the contract, AT&T will manage all aspects of CME's hosting environment -- including security, storage, databases, applications and infrastructure associated with the Web site. Additionally, AT&T will provide tape back-up and restore services supporting CME's business continuity and disaster recovery plans to ensure clients have uninterrupted access to its databases and proprietary applications. AT&T already provides CME with an integrated portfolio of networking, Internet Protocol and teleconferencing services.

"We are a leading worldwide futures exchange, and our Web site provides market participants, customers, members and shareholders around the world with access to CME's market data, product information and background about CME as a publicly traded company," said Rich Chandler, CME's Director of Technology. "We view AT&T as a technology partner that helps CME to achieve its business goals. The cme.com hosting arrangement is an excellent example of the value of this partnership."

AT&T will manage CME's Web site and applications through its integrated Global Enterprise Management System (iGEMS), an end-to-end global network management

platform that enables AT&T to proactively monitor and manage the performance of clients' networking and applications environment. Additionally, the AT&T BusinessDirect Web portal provides CME with real-time, secure access to detailed information about its AT&T-hosted infrastructure and applications.

AT&T worked closely with Sun Microsystems, an AT&T Strategic Alliance, to close the CME deal. Sun provided critical expertise on various applications within Sun architectures, allowing the development of best-in-class solutions.
