Mr. Breese brings exceptional experience and a strong track record to Clean Diesel. During his tenure at CPG, he consistently drove top and bottom line growth. He also helped to transform the way in which CPG innovated, manufactured and sold products, particularly in international and emerging markets. Under his guidance, CPG was successfully restructured, a new management team was created, and its financial performance improved.Mr. Breese succeeds Charles F. Call, who in December 2011 announced his intention to retire as President and Chief Executive Officer. "Speaking for the Board, it would be impossible to overstate how much Charlie's leadership has meant to our company – driving us into the heavy duty diesel business, steering us through the darkest days of the global auto industry's collapse in 2009, engineering the business combination of Catalytic Solutions with Clean Diesel and continuing the technological innovation that is at the heart of our products. He deserves our deepest thanks and very best wishes for future endeavors," said Mr. Ellis. Mr. Call will remain with Clean Diesel in a transitional capacity until March 31, 2012. Mr. Call will remain a member of the Board of Directors, and the Board has appointed him to serve as Vice Chairman. About Clean Diesel Technologies, Inc.
