NEW YORK, NY - October 14, 2004 - LivePerson, Inc. (NASDAQ: LPSN), a leading provider of communications solutions for online sales, marketing and customer service, today announced a partnership with Commtouch (NASDAQ: CTCHC), a global innovator of anti-spam systems, to provide spam filtration for LivePerson's 4,000-plus customers. Independent testing has shown that Commtouch's Recurrent Pattern Detection (RPD)™ technology identifies and blocks more than 97% of spam, while generating next to zero false-positives. As a result of this partnership, LivePerson customers who use its email management solutions gain effective spam protection without losing valid messages and inquiries.

LivePerson's automated email management system is just one component of Timpani, a fully-integrated online communications platform that delivers chat, email and self-service knowledge-base capabilities. Like Timpani, Commtouch spam filtration is a hosted solution. Because the filter processes all suspect email outside of a company's firewall, LivePerson customers are less vulnerable to dangerous and disruptive viruses transmitted via conventional email programs.

"Commtouch has developed one of the only spam filtration technologies available that functions effectively, efficiently and accurately," said Robert LoCascio, LivePerson CEO. "By incorporating the power of Commtouch's RPD™ technology into the Timpani platform, we prevent our customers from being bombarded with spam, so they can focus on responding quickly to email inquiries."

In marked contrast to other widely-used email systems, such as Microsoft ® Outlook ®, Timpani Email provides businesses with advanced traffic management tools, including filtering, routing, tracking and reporting. The solution enables contact centers to improve response time rates as well as increase agent productivity and customer satisfaction.

"At Commtouch, we share LivePerson's commitment to providing hosted, highly efficient technology that stays at the forefront of technological innovation," said Gideon Mantel, Commtouch CEO. "The integration of our technology with LivePerson's Timpani platform establishes a standard for email management to function at the highest level."
