Munich / Burghausen, June 28, 2006 - Wacker Chemie AG plans to expand
its polysilicon production in Burghausen by 4,500 metric tons per
year to a total of 14,500 metric tons by the end of 2009. The company
made this decision today. As announced earlier, expansion activities
already underway are scheduled to grow WACKER’s nominal annual
production capacity from the present 5,500 metric tons of polysilicon
to some 10,000 metric tons from early 2008. First material for sale
from the new, so-called "capacity expansion stage 7" is expected to
be available in Q4 2008. The new plant is scheduled to reach full
capacity by the end of 2009. WACKER has earmarked capital
expenditures of around EUR 300 million for this project.

Through this expansion, WACKER aims to meet the growing global demand
for hyperpure polycrystalline silicon expected by the company. Being
currently the second largest global producer of polysilicon, WACKER
is striving for market leadership in this segment. WACKER sees
ongoing growth of the polysilicon demand in the electronics industry
in the high single digit percentage annually during the next four
years and an even faster increase in demand in the rapidly developing
solar sector.
