Peter Leupp joins ABB Group Executive
Committee to head Power Systems division

Zurich, Switzerland, August 25, 2006 - ABB announced today that Peter Leupp, country manager of ABB in China, has been appointed to the Group Executive Committee as head of the Power Systems division. He replaces Samir Brikho who leaves ABB on October 1, 2006 to become chief executive of a United Kingdom-listed company.

Peter Leupp has been instrumental in ABB’s growth in China where he took over as country manager in 2001 and now heads a much expanded and successful operation with some 9,000 employees, in addition to his role as region manager for North Asia.

He joined ABB (Brown Boveri) in 1977 and has spent most of his career in the power technology area.

Fred Kindle, ABB President and CEO said: “Peter has already made a significant contribution to the development of ABB across the world and particularly in China. We welcome him to the Executive Committee and to his new position. With his skills and Asian expertise he will add substantial value to the top leadership of our group.”

“We also thank Samir for his many years of commitment to ABB and wish him well for the future,” said Kindle.

The Power Systems division employs 12,500 people and had revenues of more than $2 billion in the first six months of 2006.

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 107,000 people.
