ROSELAND, N.J.--(BUSINESS WIRE)--March 6, 2002

Expand Networks, a leader in the field of bandwidth optimization technology, today announced the company's support in increasing network predictability to better assure the performance of Microsoft(R) Exchange (Nasdaq:MSFT) applications and tools.

Exchange is the leader in messaging and collaboration, with more than 94 million licenses sold globally. The Expand ACCELERATORs ideally complement Exchange as they maximize Exchange investments over the existing wide area network (WAN). The Expand ACCELERATORs enable optimum use of Exchange's collaboration tools by supporting more end users on the same link while accelerating Exchange synchronization by 100-400%. Expand's network appliances also provide data integrity features that guarantee the performance of all networked applications.

"Expand's ACCELERATORs provide additional wide area network capacity and speed for leveraging Exchange's rich feature set," said Kevin McCuistion, Group Product Manager for Exchange at Microsoft. "With the ACCELERATORs, more Exchange users can benefit from existing bandwidth. Through more efficient utilization of network resources, the ACCELERATORs can speed up server-to-server Exchange replications for the most current information."

The ACCELERATORs are built on Expand's patented Enterprise Caching Technology. Enterprise Caching is an application-independent technology that focuses on increasing network capacity available to all enterprise applications: IP, non-IP, web, and non-web. The ACCELERATORs are deployed in over 150 customers worldwide, and operate on all network traffic on both ends of the Wide Area Network (WAN) - central as well as remote sites. They remove repeat data patterns from the network with important bandwidth savings. The end result is an increase in network capacity, throughput and speed of 100 to 400 percent, which ultimately translates to average payback periods of 6 - 12 months.

"Over the past 2 years we have worked with many companies using Exchange, including a Fortune 10 bank," said Talmon Marco, president and co-founder, Expand Networks. "These companies have turned to Expand so that they could divert and reinvest Telco upgrade dollars into feature-rich Exchange applications - a priority that was more tightly aligned with their corporate initiatives of operational efficiency and end-user productivity."
