2. Reasons for the revision

The ripples of economic unrest, radiating beyond the financial markets into the
real economy worldwide, has started affecting the business environment
surrounding the Company after the middle of November. Reflecting the ongoing
economic uncertainties and possible business risks attributable to further
demand declines, yen's appreciation and customer inventory adjustments
accelerating at a pace far exceeding expectations, the Company now revises
downward its financial forecast announced on April 23, 2008.
