NANJING, China — April 11, 2013 — A month ahead of schedule, the trial production for DyStar’s
additional Indigo line at the company’s manufacturing hub in Nanjing, China, had successfully
started on April 1 2013.

The latest technology and several process improvements from DyStar’s first experience at the
Nanjing plant and from the company’s global team in Ludwigshafen, Germany, were implemented. This
allows us to respond to the growing demand for the high quality DyStar Indigo Vat 40 % Solution.
