Steven D. Dalrymple Appointed CEO of USRobotics

Steven D. Dalrymple, a technology industry veteran with strong
experience leading companies in rapidly changing markets, has been
named chief executive officer of USRobotics, the company announced
today.

Mr. Dalrymple replaces Joseph Hartnett, who engineered the sale of
USRobotics to Platinum Equity in August 2005 and led the company
through its transition in the intervening year.

"Joe Hartnett played a pivotal role in positioning USRobotics for
the future," said Paul Bridwell, senior vice president at Platinum
Equity. "We are confident there will be a smooth transition as he
passes the reins to Steve Dalrymple."

Mr. Dalrymple most recently served as CEO of another Platinum
Equity company, Vanguard Managed Solutions LLC, which is the largest
independent managed services provider in the United States and a
leading source of enterprise networking equipment. Mr. Dalrymple will
remain on the Board of Directors at Vanguard Managed Solutions LLC.

"Steve brings a strong background in enterprise networking to
USRobotics," Mr. Bridwell said. "At Vanguard he led a business
transformation that re-established the company in the managed services
space, while sustaining both customer retention and financial
performance."

"We expect him to be similarly effective at USRobotics, guiding
the company through a rapidly changing marketplace and building a
successful, long-term future for the company."
