3Com Licenses Parthus Technology for Use in Mobile Product Line

SAN JOSE, Calif. and DUBLIN, Ireland — January 24, 2001 — Parthus Technologies PLC (Nasdaq: PRTH) (LSE: PRH), a leading supplier of platform-level intellectual property for the mobile Internet market, today announced that it has signed a portfolio licensing and royalty agreement with 3Com Corporation (Nasdaq: COMS) to deliver technology for use in 3Com's wireless and mobile product line development.

As part of the agreement, Parthus will deliver a range of Intellectual Property platforms that includes Parthus' BlueStream(TM), NavStream(TM) and MediaStream(TM) technologies. Each platform is created to combine low power consumption requirements with high levels of on-chip functionality; key factors in the success of mobile devices.

"Wireless allows 3Com to provide radically simple connections for our customers," said Rick Maule, general manager of the Mobile Connectivity Division of 3Com. "Our next generation of wireless and mobile products are a natural extension and will complement our current role in LAN technologies. This alliance with Parthus, a leader in the mobile Internet, provides us with additional wireless and multimedia technology, which enhances our existing mobile IP portfolio."

"3Com is one of the world's leading technology companies with a long history of innovation," said Kevin Fielding, chief operating officer of Parthus Technologies. "We believe our agreement with 3Com accelerates the development of a range of wireless products that converge mobile communications and the Internet seamlessly."

While every Parthus platform can be converged in one chip solution, BlueStream, NavStream and MediaStream are also designed to operate as stand alone platforms that provide best-in-class performance.
