Barry Reisberg: We're very fortunate in having here the regulatory persons from the United States, Canada, and Germany, in the persons of Paul Leber, Catherine Petersen, and Ursula Kern. I hope that we can proceed more or less in the fashion that the last round table went, which is your reactions as you've been listening to what you've been hearing today. And also your reactions, more generally, in terms of the field. We'll start with Dr. Kern and then Dr. Petersen and then Dr. Leber.
