Platinum Equity Completes Acquisition of USRobotics®

LOS ANGELES (September 20, 2005) – Platinum Equity announced today that it has completed the acquisition of pioneering network and Internet connectivity provider USRobotics. The transaction was announced on Aug. 15.

With an installed base of more than 100 million products in more than 80 countries worldwide, USRobotics is one of the world’s leading producers and distributors of broadband and analog modems, and wired and wireless networking solutions.

Founded in 1976 by three University of Chicago students working out of a Skokie, Illinois garage, the company was named after the “greatest company in the known galaxy” – U.S. Robots and Mechanical Men – from the science fiction novel I, Robot by Isaac Asimov.

From those entrepreneurial beginnings, USRobotics quickly emerged as the world’s No. 1 selling modem brand, as millions of PC users around the globe first connected to the Internet with the company’s analog modem. Today, it is the most recognized product line in its category within the Internet access industry.
