RPX(TM) Trading Volume Exceeds $250 Million in First Seven Weeks of Trading

Variety of Participants Continues to Grow


NEW YORK, NY--(Marketwire - November 7, 2007) - Since the inception of trading on September 17, 2007, derivatives volume in the Residential Property Index™ (RPX) market has passed the quarter of a billion dollar threshold, according to Radar Logic Incorporated, the data and analytics company upon whose Daily Prices the index is based. The company reports that flows represent positive two-way activity, and participation has begun to include a variety of end users.

According to Michael Feder, President and CEO of Radar Logic, "In light of what has been happening on Wall Street during the past two months, we view this level of activity as very encouraging. With all the obvious distractions facing traders and their customers, having reached this milestone so quickly is evidence of RPX's relevance to and interest in the capital markets."

Mr. Feder and Jonathan Miller, Executive Vice President and Director of Research of Radar Logic, will discuss current activity in RPX and the U.S. residential housing market later this week in featured presentations at Marcus Evans' "Discovering the North American Property Derivatives Market" conference in New York City. In addition to a full review of RPX and its specific benefits to users, Mr. Feder will address trading to date and how the market can achieve continued success. Mr. Miller's presentation will focus on results of Radar Logic's ongoing research into the U.S. residential housing market, including current market patterns and trends.
