BackWeb Provides Push Infrastructure for Siemens ICN's Intranet

Siemens Uses Patented Push Technology to Distribute Information to Thousands of Users via Web-based VD-Infochannel

SAN JOSE, Calif.— September 5, 2000 — Siemens AG today announced that it has selected BackWeb® Technologies (Nasdaq: BWEB), a leading supplier of push for e-business solutions, to provide the Polite™ push infrastructure for Siemens' ICN (Information and Communication Networks) division, one of the three information and corporate technology divisions at Siemens AG. With BackWeb's patented Polite™ push technology, the ICN Intranet proactively distributes customized content directly to users‘ desktops.

Siemens selected BackWeb after a two-year evaluation. Using BackWeb Foundation, Heidelberg firm Expert Center Rodo Media developed VD-Infochannel, an all-inclusive communications application deployed in spring 1999. With the Siemens ICN Intranet growing steadily, 7,500 of Siemens' 60,000 Intranet users already receive proactive deliveries of critical information.

Supported by BackWeb's push technology, Siemens managers can supply its distribution staff with the latest information, including distribution releases, product information and price lists. This information is generated in the VD-Infochannel headquarters in Munich and is delivered directly to users' desktops with the help of BackWeb's Polite Agent™ and Flash features. These unique capabilities ensure that Siemens uses only available network bandwidth for deliveries, thus minimizing the impact that content deliveries have on system and network performance. BackWeb's Flash feature also allows Siemens to employ multimedia alerts that instantly inform users about the arrival of important or time-sensitive information.

The push-enabled VD-Infochannel provides easy access to Siemens Intranet's most important sources of information, thus reducing the time it takes to research topics and locate materials. With BackWeb, the Siemens network also automatically updates important files and materials, and distributes information culled from some 25 Web channels, including SAP information or news, share prices and news articles.

With BackWeb's patented Polite push technology, Global 2000 companies can deliver multimedia-rich digital packages of any size or format, including audio, video, graphics and html. BackWeb's Polite Agent avoids disrupting the consumer by using only available bandwidth and politely delivering the information in the background.
