Stock Exchange Announcement No. 17/11

Change in Management

The Board of Directors of Topsil Semiconductor Materials A/S has mutually
agreed with Managing Director Keld Lindegaard Andersen that he resigns from his
position in the company as from today.

In the years 2005-2010 Keld Lindegaard Andersen has been at the head of a
positive growth in Topsil, where activities and market position have been
considerably strengthened.

However, in 2011 Topsil has seen an unsatisfactory financial development, due
to recession in the market and a number of challenges in production and
operations. Therefore, the Board of Directors wishes to strengthen the
managerial focus on operational execution, including efficiency improvement,
qualification, product development and implementation of new production
machinery.

On behalf of the Board of Directors I wish to thank Keld for his significant
efforts to bring Topsil on the right track. Topsil has become a leading player
in our niche markets, and Keld has been a determining factor in securing the
company a solid business platform.

The Board of Directors has initiated an external process to engage a new
Managing Director, who will be charged with realising the strategic objectives
of the company and re-establishing the earning capacity. In the meantime the
EVP, Director of Logistics, Sales and Marketing of Topsil, Jørgen Bødker, has
been appointed Managing Director ad interim.
