Dow Corning Opens Middle East Headquarters

Midland, Mich.-based Dow Corning Corp., a supplier of silicone products for textile applications,
has opened a headquarters location for the Middle East in Bahrain. The office will employ as many
as 20 people in its first year performing a variety of functions from engineering and chemistry to
sales. The operation will bring Dow Corning’s silicone-based materials and solutions directly to
the region’s industries including textiles.

“The Middle East is growing rapidly and quickly diversifying its business footprint,” said
Dr. Stephanie A. Burns, chairman, president and CEO, Dow Corning. “We recognize the region’s
growing impact on the global economy and are now better positioned to share the benefits of Dow
Corning’s silicone-based materials and technology to help the region continue to grow and compete
in the global economy over the long-term.”

“We have done extremely well to grow our business in this region in the last few years, even
when servicing from afar,” said Jen-Paul Mollie, president, Middle East, South Asia and Africa, Dow
Corning. “Now is our chance to drive business forward through both the Dow Corning® and Xiameter®
brands. With the special challenges of high temperatures, sand and wind, there will be no end of
uses for the incredible silicon atom in the area. The potential is yet to be realized.”
