Bayer MaterialScience’s carbon monoxide (CO), diphenylmethane
diisocyanate (MDI) and polycarbonate production facilities at its
Krefeld-Uerdingen, Germany, site are once again operating at full capacity.

Due to operational problems affecting carbon monoxide (CO) production at this
plant, the facility had been operating at below total capacity since
mid-November 2006. As a result, the company declared a force majeure for
MDI in the Europe, Middle East, and Africa region (EMEA). This declaration
has now been withdrawn. The shortfall in polycarbonate production was partially compensated for by sourcing supplies from other sites and making individual arrangements with customers.

At the end of September a production line for toluene diisocyanate (TDI) at
the Bayer MaterialScience site in Baytown, USA, had to be shut down
following an explosion. This production line has been repaired and is now
gradually being brought back to full capacity. As soon as the situation
permits, the declaration of force majeure will be lifted here too. This is
scheduled for January 2007.

With sales of €10.7 billion in 2005, Bayer MaterialScience AG is one of
the world’s largest polymer manufacturers.
