Austin, Texas June 28, 2011 — SACHEM announces a price increase of 10% on the supply of Tetramethylammonium Chloride (TMAC) effective August 1, 2011 or as contracts allow.

The price increase is necessary due to continued increases in energy, logistics, and raw materials costs. SACHEM has worked diligently during the year to control these costs but we are no longer able to absorb them. In order to insure continued timely supply of product, we must take the unfortunate action of increasing prices. As always, we thank you for your support and please contact your SACHEM Sales Associate if you have any further questions.
