According to this changing effects, the forecast financial results for the second quarter of fiscal year ending December 31, 2007, which were announced on April 26, 2007, have been revised as set forth.

1. Reason for changing U.S. GAAP to Japan GAAP

According to our announcement on April 26 and June 1, 2007, the delisting of its American Depositary Shares (“ADR”) from the NASDAQ Stock Market (“NASDAQ”) took effect upon the commencement of trading on May 31, 2007. In addition, the Company submitted Form 15F to U.S. Securities Exchange Commission (the “SEC”) on June 27, 2007. The Company expects that the termination of its SEC reporting obligations will become effective 90 days after the date of filing the Form 15F with the SEC, or such shorter period as the SEC may determine. However, upon filing the Form 15F on June 27, 2007, the Company’s obligations to file reports on Form 20-F and Form 6-K with the SEC has immediately been suspended.

In light of these circumstances, though it has not ensured yet that the termination of its SEC reporting obligations will become effective, the Company has adopted and started to disclose with the accounting principles to Japan GAAP for the first half of the fiscal year ending December 31, 2007 and thereafter.

2. Revision of forecast of financial results for the second quarter of FY2007 (Japan GAAP)

(April 1, 2007 to June 30, 2007)

Based on the above result, the forecast of financial results for the second quarter of fiscal year ending December 31, 2007, which were announced with U.S. GAAP on April 26, 2007 should be revised with Japan GAAP as follows.
