eStara CEO John Federman to Participate in Web 2.0 Technology Panel at Shop.org's 'Online Retail Boot Camp'

Market Wire, October, 2006

Who:     John Federman, CEO, eStara

What:    With the explosion of Web 2.0 tools for e-commerce, retailers
         are attempting to weed through the hype to discern what solutions
         make sense for their business.  Shop.org's Online Retail Boot
         Camp, which is being held on October 10th in New York, is
         designed to provide actionable information for online retailers
         who want to learn about the latest technology advancements that
         will help differentiate their site from their competition.

         During the panel entitled "Web 2.0: A Peek at What's Here and
         What's Coming - Part 1," John Federman will discuss the rising
         prominence of new technologies, like proactive conversion
         solutions, such as click to call and click to chat, which are
         driving the evolution of online retailing from what was once a
         purely self-serve medium to one that encourages communication
         and collaboration between buyers and sellers.

         Additionally, Federman will highlight how online retailers can
         implement these technologies within their multichannel marketing
         strategies to reach out to customers at key points in the sales
         cycle -- the equivalent of an in-store salesperson approaching
         and assisting a would-be buyer.

         "Even as consumers become increasingly technology-savvy, many
         still rely on customer service representatives as the leading
         means to acquire information about products," said Federman.
         "Click to call and click to chat are proven solutions that
         increase online sales conversions, and improve consumer loyalty."

When:    Tuesday, October 10, 2006
         1:00 p.m. EDT

Where:   Shop.org's Online Retail Boot Camp
