Pentair Names Charles M. Brown President and Chief Operating Officer Focused On Pump and Pool Markets

Brown’s new role in water underscores company’s focus on growth

GOLDEN VALLEY, Minn. — March 30, 2005 — Pentair (NYSE: PNR) today announced that Charles M. Brown will rejoin the company as president and chief operating officer of Pentair Water Group’s Pump and Pool operations, effective April 4. This newly created position will report to the Office of the Chairman, which consists of Pentair Chairman and Chief Executive Officer Randall J. Hogan and Vice Chairman Richard J. Cathcart. Brown had served as president and chief operating officer of Pentair’s Tools Group from 2003 until it was acquired by Black & Decker Corporation in October 2004.

“I am delighted Charley is rejoining Pentair, where his talent will be deployed in water, our largest group and one with high market growth potential,” said Hogan. “Charley is a proven leader with a demonstrated understanding of Pentair’s values and operating disciplines. His leadership, combined with the already strong leadership in our Water Group, will accelerate growth and capture even greater benefits from Pentair’s operating initiatives.”

Hogan added, “The water markets remain an attractive opportunity for Pentair. This appointment is another example of our commitment to deploy talent to capture growth opportunities and drive shareholder value.” In February, the company named Cathcart vice chairman with new responsibilities for international growth and business development in addition to his continuing role as strategic leader of the Water Group. Brown’s appointment supplements Cathcart’s strategic leadership with an intensified focus in the Pump and Pool and Spa operations.
