John Federman of eStara Joins Kelsey Group Panel on the Convergence of the Phone With Local Internet Advertising

RESTON, VA -- (MARKET WIRE) -- March 13, 2007 --

Who:    John Federman, CEO, eStara

What:   Although Alexander Graham Bell never had the pleasure of
        searchin for a local business online, his greatest
        invention, the phone, is playing an increasing role in
        how people interact with IYP (internet yellow pages) and
        local search advertisers.  Amongst the phone-enabled
        applications, stakeholders are trying to master how to
        merge the phone with commerce on the Web -- after all, voice
        remains the preferred method of communication for most people.

        In a panel discussion of key industry figures, John Federman will
        discuss the current and future impact of the phone on the growing
        local advertising market.  With many small businesses preferring
        to deal in voice transactions, Federman will point to key eStara
        customers that have successfully bridged buyers and sellers via
        the phone and the benefits that they have received as a result.

        The Kelsey Group predicts that local search is poised to reach
        $2.6 billion in U.S. revenues, while IYP revenues will rise at a
        nearly 30 percent annual growth rate, from $624 million to $2.3
        billion in 2011.  Additionally, a recent study from the firm
        forecasts an increase in average ad conversions of 18 percent.

        The panel, "The Phone's Real Impact on Local Advertising," will
        take place at The Kelsey Group's annual Drilling Down on Local
