Non-consolidated (1) 1st Half(from April 1st 2005 to September 30th 2005) (Mil.

Reason for the forecast revision (1) 1st half of the fiscal year ending March 31, 2006 There was a more favorable than expected growth in demand for eDetails as a result of an increase in Medical Doctor ("MD") members in the first half of the current fiscal year by 16,000 to 113,000 MDs, coupled with an improvement in the frequency by which MDs are using the service, in addition to such factors as the increasingly active use of the "MR-Kun" service by client companies due to an increase in the number of products handled by the service. As a result, sales revenue and income particularly from the marketing support to healthcare companies business are expected to exceed the April 21, 2005 forecast. (2) Fiscal year ending March 31, 2006 The revision to the forecast for the fiscal year ending March 31, 2006 is in response to the revision to the operating results forecast to the 1st half of the fiscal year ending March 31, 2006. In addition, we also anticipate favorable growth in the second half of the fiscal year reflecting such factors as an anticipated increase in the number of new clients using the "MR-Kun" service coupled to increased use of the service. However, as a result of certain uncertain factors relating to the extent of this additional growth, the revision to the forecast to the full fiscal year only reflects the impact of the addition from the first half revision, in addition to the effect of adjusting the forecast numbers into 10 million yen units. Looking forward, we plan to carry out further revisions to our operating results forecast as necessary when the impact of these factors can be more precisely determined. (For your reference): As of this forecast revision announcement, subsequent forecasts will be announced using the 10 million yen unit.
