Material Sciences Corporation Appoints Clifford D. Nastas as Chief Executive Officer

Ronald L. Stewart, CEO Since 2004, to Retire

ELK GROVE VILLAGE, Ill., Nov. 22 -- Material Sciences Corporation announced today that its board of directors has appointed Clifford (Cliff) D. Nastas as Chief Executive Officer, effective December 1, 2005. Nastas, who will also join the company's board of directors, currently serves as president and chief operating officer of the company, and succeeds Ronald L. Stewart, who is retiring from his position and the company's board of directors. Material Sciences is a leading provider of acoustical/thermal and coated metal applications.

"We are pleased to appoint Cliff Nastas to lead Material Sciences," said Dr. Ronald A. Mitsch, non-executive chairman of the board of Material Sciences. "Cliff is a dynamic individual with considerable experience working with the automotive companies that are a large part of our client base. He has provided the leadership for the development of our Quiet Steel(R) business, which has a significant position in the noise, vibration and harshness (NVH) market, and knows the metal coating industry well. His selection reflects the board's belief that he is the right person to move the company forward at this time."

Since his appointment as president and chief operating officer in June 2005, Nastas, 42, has been responsible for all operations, sales and marketing, purchasing and human resources functions for Material Sciences. He previously served as vice president and general manager of the company's Engineered Materials and Solutions Group from May 2004, after having been promoted to vice president of sales and marketing in 2003. Nastas joined Material Sciences in 2001 as vice president of marketing for the company's Laminates and Composites Group. He previously held management positions with Honeywell, Ford Motor Company and Avery Dennison. He holds a master's degree in business administration from Case Western Reserve University and a bachelor's degree in chemical engineering from Wayne State University.

"This is a terrific opportunity, and it is an honor to be selected as Material Sciences' CEO," Nastas said. "Material Sciences has a great reputation in the market and a strong executive team, and I look forward to working with them as we build on our solid track record."

"Our Quiet Steel products are already used by many automotive OEM's in the U.S. and Europe, and our solid relationships with them will be enhanced by our Applications Research Center in Canton, Mich., which will open next spring. Our joint venture with Arcelor, a leading global steel company, gives us a strategy for penetrating the European auto industry, and our ongoing discussions regarding joint ventures in Korea, China and Japan are encouraging," Nastas said.

Stewart, 62, served as chief executive officer and director for Material Sciences since his appointment in March 2004, and also held the title of president until Nastas was appointed to this position in June 2005. The positions of president and chief operating officer will remain vacant following Nastas' promotion.

"The board extends its gratitude to Ron Stewart for his service and dedication to the company during his tenure," Mitsch said. "The company's financial performance has improved considerably under his leadership and he leaves the company well-positioned for the future."

The board also announced that it will form an executive committee of the board whose duties will include advising the CEO with respect to strategic and operational planning and management development. Curtis G. Solsvig III, a current director, will serve as its chairperson and its other members will be Mitsch and Nastas.
