Reason for the forecast revision Results for the first three quarters of the fiscal year ending March 31, 2006 (the period from April 1st 2005 to December 31st 2005) have exceeded the levels of our previous forecast resulting mainly from the favorable growth of our marketing support to healthcare companies business especially the "MR-Kun" service and from the favorable growth of research orders received. We also anticipate sales revenue to continue to exceed the levels of our previous forecast for period January 1st to March 31st, in association with increased use of the "MR-Kun" service. In addition, although we anticipate the occurrence of one-time selling, general and administrative costs, we do not anticipate any changes to our business structure. Based on the aforementioned reasons, we have revised our forecast for the fiscal year ending March 31, 2006.
