Ciba Sells Division After Successful Restructuring

Ciba Specialty Chemicals Inc.,
Switzerland, and Morgan Grenfell Private Equity (MGPE) recently announced that they have signed a
contract under which MGPE will buy Ciba’s Performance Polymers division.

“Ciba has successfully restructured the Performance Polymers division and has now found a
strong new partner to take over the business,” said Rolf A. Meyer, chairman and CEO, Ciba Specialty
Chemicals. “This move also underscores Ciba’s strategy to focus its portfolio on specialty
chemicals rather than specialty materials and allow us to further promote innovative and high value
effects for customers and consumers.”

Graham Hutton, chief executive, MPGE said: “The Performance Polymers division is a
high-quality branded asset with top-line growth potential driven by its leading technological
position. It is one of the world’s top three epoxy resins manufacturers and has strong positions in
specialty applications such as advanced tooling, adhesives and photo polymers.”

Ciba plans to use the proceeds from the sale to repay debt and for corporate development

MPGE announced that it will appoint Karl-Gerhard Seifert, formally CEO of Clariant, as
non-executive chairman of the Performance Polymers business. The headquarters of the Performance
Polymers business will be based in Basel, Switzerland.
