As a standalone, privately held company, Styron (www.styron.com)
will be a leading materials company with global reach and a unique product
portfolio bringing together plastics, rubber and latex businesses that share
feedstocks, operations, customers and end users. The company has
approximately $3.7 billion in revenue (based on 2009 data), with 20
manufacturing sites and 1,900 employees based in 30 countries.

"Styron is a brand new global materials company that stands on seven
decades of heritage - built upon a history of strengths in technology,
application expertise, operations excellence, innovation and global reach,"
said Christopher D. Pappas, President and Chief Executive Officer of Styron.
"But while we're proud of our past, it's where we're going that excites us
the most. We bring the same world-class team our customers have come to trust
- talented employees with deep technical knowledge and experience. That same
team is now fully dedicated to helping our customers stay at the forefront of
their industries, and enabling them to turn their ideas into marketplace
reality."

"We believe strongly in Styron's ability to realize its growth potential
as a stand-alone global business, and to continue to build deep and lasting
customer relationships," said Steve Zide, a Managing Director at Bain
Capital. "Styron has many significant assets, including a solid and
innovative product portfolio and a long-term, value-added partnership with
Dow. We look forward to working with Chris Pappas and the experienced
management team to strengthen Styron's leadership position, and to grow the
business through geographic expansion and select acquisitions."

The company benefits from a leadership position in its two flagship
products, Polystyrene and Styrene-butadiene Latex, and a broad geographic
reach, with a strong manufacturing and Research & Development presence in all
regions. Styron's broad plastics offering includes Polystyrene, Co-polymers
