Douglas R. Matthews Appointed Vice President and General Director of U. S. Steel Serbia

United States Steel Corporation (NYSE: X) announced today that Douglas R. Matthews has been appointed vice president and general director of U. S. Steel Serbia, effective May 1. In his new position, Doug will oversee the U. S. Steel Serbia operation.

"Doug's recent assignment as general manager of blast furnace engineering, coupled with his extensive steelmaking, operating and managing skills, make him a good fit for this challenging and important position," said U. S. Steel Chairman and Chief Executive Officer John Surma.

Matthews joined U. S. Steel in 1988 as a management associate at the Edgar Thomson Plant, Mon Valley Works' steelmaking facility. He progressed through several supervisory positions in the Electrical and Caster Maintenance departments at Edgar Thomson before he was named senior process leader of coating operations at the Irvin Plant, where steel slabs from Edgar Thomson are rolled into sheet products.

In 1997, he was transferred to Pro-Tec Coating Company in Leipsic, Ohio, U. S. Steel's joint venture with Kobe Steel of Japan, where he managed the installation and commissioning of the facility's second continuous galvanizing line. From 1998 to 2003, he oversaw iron producing at the former USS/KOBE steelmaking venture in Lorain, Ohio, and at Gary Works, respectively. He was named division manager of steelmaking and casting at Gary Works in 2003, and was promoted to his most recent position, general manager of blast furnace engineering and technology, at Pittsburgh headquarters in 2005.

Matthews graduated from Pennsylvania State University in 1987 with a bachelor's degree in electrical engineering, and received a master's degree in business administration from Duquesne University in 1993.

Matthews and his wife, Kimberly, and their two children, Claira, 4, and Caden, 2, will relocate to Serbia.
