Price Increase Notice

SCHENECTADY, NY – November 1, 2009 - SI Group, Inc. is announcing a price increase on all Para Tertiary Butyl Phenol and Para Tertiary Octyl Phenol based resins effective October 15, 2009. This increase is due to a change in the economics of Isobutylene (IB) and Di-Isobutylene (DIB). North American IB and DIB producers have been impacted by changes in their supply chains, including the bankruptcy of a key feedstock supplier. SI Group has worked diligently to mitigate the effects of these changes by securing supply positions with IB and DIB vendors.

SI Group is also announcing a price increase on Nonylphenol and Amylphenol based resins effective October 15, 2009, due to significant olefin cost changes.
