Business Editors/High-Tech Writers

SAN FRANCISCO--(BUSINESS WIRE)--Aug. 21, 2001

Critical Path, Inc. (Nasdaq:CPTH), a leading global provider of communication solutions to carriers, service providers and corporations, today announced it is providing Deutsche Post AG with the directory and meta-directory technology necessary to create a comprehensive meta directory solution for the German Postal Service's `User and Resource Management Solution' (URML) project. Under a contract that was completed last quarter, Deutsche Post AG is leveraging Critical Path's Directory Server and Meta-Directory to unify existing user profile data from its disparate range of existing directory services and other sources to create a single centralized meta-directory. The flexible architecture of Critical Path's Meta-Directory provides Deutsche Post with the best cost performance by protecting and leveraging the investment in its existing infrastructure and enabling all directory data to be accessed and managed from a central location.

As part of its URML project, Deutsche Post AG turned to Critical Path to provide a Web based, user/resource management view that integrates all the different data sources and platforms that exist throughout the group. Deutsche Post is leveraging the extensive range of connectors in Critical Path's Meta-Directory to unify the dispersed directory information found in the group's distributed MS Exchange applications, HR-Systems, the telephone switchboards, and the Active Directory and Firewall/Proxy Servers.

In a subsequent phase of the URML project, Deutsche Post AG plans to incorporate meta-directories from other divisions within the organization (Danzas, Postbank and Euro Express) under a single enterprise directory. This will simplify the exchange of electronic information between staff across all divisions of the organization as well as ensure that data is kept up-to-date and accurate at all times.

"Deutsche Post AG has been an important customer for Critical Path and we are very excited to be working closely with them on their eBusiness expansion," said David Hayden, founder and Executive Chairman of Critical Path. "We believe postal authorities are natural providers for trusted eBusiness services and Deutsche Post AG has recognized the value of a directory infrastructure to manage the delivery of a comprehensive suite of eBusiness services."

The ability of Critical Path's messaging and directory infrastructure to scale to support millions of users with the high performance, reliability and the security necessary for eBusiness, is a key reason that worldwide postal organizations such as the UK's Royal Mail ViaCode, the Swedish and Finnish post offices, and La Poste France have selected Critical Path's technology. Critical Path's Directory and Meta-Directory technology enables companies to leverage their existing infrastructure to bring data together, making it is possible to distribute user profiles accurately and efficiently in a timely manner across their enterprises and extranets.
