2. Reasons for the revisionFirst Half Fiscal 2010 (April 1, 2010 – September 30, 2010)
With regard to the non-consolidated performance forecast, net sales are expected toincrease, as there are expected to be strong sales of polycrystalline silicon and vinyl
chloride monomer. In addition to the aforementioned factor, as raw materials prices areexpected to be below what was estimated at the announcement of the previous
performance forecast, and more progress is expected to be made with streamlining
measures of our cement operations than anticipated in the previous forecast, operating
income is also expected to increase.
It is expected, however, that ordinary income will increase by no more than ¥0.5 billion
due chiefly to a foreign exchange loss incurred in the first quarter. Net income is estimatedto decrease by ¥0.5 billion owing mainly to an extraordinary loss due to liquidation of asubsidiary.
With regard to the consolidated performance forecast, net sales will be affected by weaksales of cement sales companies, liquidation of the subsidiary and other factors, on top of
the above-mentioned factors on the non-consolidated basis. However, net income isexpected to increase, mainly because a subsidy will be posted as an extraordinary gain.
Based on these factors, we have revised the performance forecast for the First Half Fiscal
2010 (April 1, 2010 to September 30, 2010), announced on May 12, 2010.
Fiscal 2010 (April 1, 2010 – March 31, 2011)
With regard to the performance forecast for Fiscal 2010 (Full year, April 1, 2010 to March31, 2011), we have not revised the figures announced on May 12, 2010, as future prospects
for the Company’s business environment are uncertain.

※ The performance forecast contained in this material has been prepared on the basis ofinformation available at this point and certain assumptions which are judged to be rational,
and may be substantially different from the actual performance because of various factorsthat may arise from now on.
