We don't anticipate many changes in jobs as a result of the merger. This merger is about bringing two complementary businesses together, so we believe this merger creates the opportunity for new and additional types of career growth and collaboration. Q. WILL WE BE MOVING? A. Both companies are growing very rapidly and are the in the midst of aggressive office space expansion. In the near term, we have no plans to move office locations other than the plans that are already underway. Of course, we will continually assess our space requirements and keep everyone informed of any new developments in this area. Q. WHAT ABOUT MY BENEFITS? A. As you know, we are in the midst of a benefits review, independent of this merger.

There will be no change in Media Metrix options. Q. ARE THERE PLANS FOR THE TWO COMPANIES TO FULLY INTEGRATE? A. Unlike the RelevantKnowledge merger, this is a merger of two different companies in two different but complementary businesses coming together, so a full integration is not what we have in mind. Media Metrix and Jupiter will continue to be run as independent business units, and we will look for synergy through cross-selling, cross-marketing, and cross-product development. One important thing to keep in mind is that this merger transaction will not officially "close" for another 90 to 120 days. That means we can make plans about how to best work together, but we will not be able to operate as a single company until after that time. Q. HOW WILL THE MERGER AFFECT OUR PRODUCT AND SERVICES OFFERINGS? A. Media Metrix and Jupiter will continue to offer the breadth of products we have today, the merger will create tremendous synergies to create additional products, client categories and, importantly, further global expansion. 4 Q.
