BackWeb and Network Associates Extend Partnership

Network Associates Resells BackWeb's Distribution Technology With Its New iZAC Offering

San Jose, Calif. (April 6, 1998) -- BackWeb, Inc. and Network Associates (NASDAQ: NETA), formerly McAfee Associates, today announced they are extending their strategic partnership as Network Associates combines its SecureCast offering, which includes BackWeb's knowledge distribution technology, with its Zero Administration Client (ZAC) suite. This combination will yield Network Associates its new iZAC offering, as a component of the ZAC integrated PC management suite, which includes asset and inventory management, software distribution, software metering, PC remote control and desktop lockdown capabilities.

"Network Associates' SecureCast customers have enjoyed the benefits of BackWeb's distribution push technology for more than a year and we're pleased to expand our relationship with BackWeb to provide those benefits to our iZAC customers," said Zach Nelson, general manager of Network Associates' Total Service Desk Division.

Network Associates' customers using iZAC will enjoy the benefits of BackWeb's proprietary Polite Agent™ distribution technology. BackWeb's bandwidth-friendly technology distributes updates over intranets, extranets and the Internet, only when bandwidth is available. BackWeb's Polite Agent does this by monitoring a user's network connection and reducing or suspending downloads when bandwidth usage is high. This ensures that users are never interrupted by BackWeb downloads.

BackWeb's Polite Agent technology also provides interruptible, differential and compressed, byte-level downloads. This is key for remote, dial-up users who can easily interrupt their network connection during a download. When these users re-connect to the network, BackWeb simply begins downloading at the exact byte where it left off. The differential downloads also enable BackWeb to deliver only the bytes of information that are new. In situations where someone updates and redistributes a large file, this level of bandwidth conservation is key.

"BackWeb is excited to have its knowledge distribution and polite technology integrated in Network Associates' new iZAC offering," said Gwen Spertell, BackWeb Technologies' senior vice president of sales, marketing and business development. "With iZAC, Network Associates' customers are truly receiving a robust administration system that will help them increase effectiveness and reduce the costs associated with software management."

BackWeb and Network Associates' began their partnership in January 1997, when Network Associates began distributing anti-virus updates to its ViruScan customers and incorporated BackWeb into its SecureCast offering. Network Associates has thousands of desktops using SecureCast with BackWeb's distribution technology today.
