New Name Reflects Growth Strategy

This name change does not change the company's existing reporting structure or brand positions. Technical Products will continue to serve the electrical, electronic and thermal markets under its primary brands: Hoffman®, Pentair Electronic Packaging™, Schroff®, Taunus™, Aspen Motion Technologies, Birtcher, Electronic Solutions and McLean Thermal.

"Pentair's strategy for this business includes expansion into markets adjacent to our previous base of electrical and electronic enclosures. The recent acquisition of thermal management businesses animates this strategy," said Randall J. Hogan, Pentair chairman and chief executive officer. "Technical Products, the new name, more accurately reflects the reality of our business today by encompassing the increasingly broad range of products we make for the electrical and electronic industries," he added.

The company announced the completion of the acquisition of McLean Thermal Management, Aspen Motion Technologies and Electronic Solutions businesses on December 1, 2005. These businesses provide thermal management solutions and integration services to the telecommunications, data communications, medical and security markets.

"We are excited by the opportunities we see to innovate and grow the Technical Products business. We continue to look for additional opportunities for growth," Hogan added.
