STAMFORD, Conn., May 1, 2001 - John Duerden today was appointed the new CEO of Xerox Engineering Systems (XES), succeeding Agnes Lewis who is leaving the company to pursue outside interests. Duerden joins XES following a distinguished career, which includes 20 years with Xerox Corporation in several senior staff and operations positions, and six-and-a-half years with Reebok International where he built the group's international operations to sales of $1.5 billion and became the company's President and Chief Operations Officer. Duerden most recently served as Chairman and CEO of Dictaphone Corporation, where he led the acquisition of the company from Pitney Bowes in August 1995 and managed its successful turnaround and subsequent sale to the Belgium speech and language company Lernout & Hauspie in May 2000. "XES' strong heritage of product innovation and leadership was a key factor in my decision to serve as the company's CEO," said Duerden. "I look forward to helping build upon that tradition while also being deeply involved in charting XES' strategic approach to customer service and finding new ways to expand applications in wide-format document management."
