Sinterama, Indorama Ventures To Acquire Trevira

A consortium comprising Thailand-based polyester polymer and fiber manufacturer Indorama Ventures
PCL and Italy-based dyed polyester yarn manufacturer Sinterama S.p.A. has agreed to acquire
polyester fiber and filament manufacturer Trevira GmbH, Germany. The transaction is expected to
close in the first quarter of 2011.

Trevira, which was re-established in January 2010 in the wake of its insolvency in 2009, has
manufacturing sites in Germany and Poland and employs some 1,350 workers. The company will become
part of Indorama’s and Sinterama’s global network under a new joint venture company, but will
continue to operate as an independent company.
