Transaction Expands Proxim’s Leadership Position in Wireless Networking Infrastructure Warburg Pincus and Broadview Capital to Invest in Proxim in Support of the Acquisition Sale Will Allow Agere To Sharpen Strategic Focus On 802.11/Wi-Fiâ„¢ Components SUNNYVALE, Calif. and ALLENTOWN, Pa. – June 17, 2002–Proxim Corporation (Nasdaq: PROX), a leading manufacturer of wireless networking equipment, and Agere Systems (NYSE: AGR.A, AGR.B), the world leader in communications components, today announced that Proxim has agreed to acquire the 802.11 wireless local area network (LAN) equipment business of Agere Systems, including its ORiNOCO product line, for $65 million in cash.

With the addition of ORiNOCO, Proxim will be the premier wireless equipment company with leadership positions in 802.11 enterprise LAN, public wireless access, distributed broadband and carrier-grade wireless backhaul systems markets. Under the agreement, Proxim will acquire assets primarily used by Agere in its wireless LAN equipment business, including a broad offering of wireless LAN products used in homes, small offices, enterprises, service providers and outdoor environments. Agere will retain its 802.11/Wi-Fi chips, modules, and cards business, representing the majority of Agere’s total Wi-Fi business. The sale will allow Agere to sharpen its focus on providing Wi-Fi component solutions for the emerging wireless computing, networking and entertainment markets.

“This transaction provides the scale, scope and depth that will allow us to continue our consolidation of the wireless infrastructure business, and to fulfill our vision of integrated wireless connectivity from the core network to devices in a home, office or public space,” said Jonathan Zakin, Proxim Corporation Chairman and Chief Executive Officer. “Upon closing of this transaction, we will provide investors with the broadest wireless pure play in the industry.”

The transaction enables the company to immediately realize revenues from the world’s largest installed user base of 802.11b infrastructure, which can in turn be upgraded to 802.11a technology over time. It also allows Proxim to accelerate revenues in the wireless WAN business by two quarters or more with a complete product line for the low-end bridging and last mile access markets. As a result, the company expects the transaction to be accretive in the first full operating quarter following the close. Agere and Proxim anticipate closing the transaction within 60 days, subject to regulatory approval and other customary closing conditions.

“In terms of positioning, customer base, technology portfolio and talent, this acquisition brings Proxim to the forefront of the wireless networking infrastructure businesses,” said David King, Proxim Corporation President and Chief Operating Officer. “With ORiNOCO, we obtain market leadership in 802.11b Wi-Fi enterprise network equipment, which complements Proxim’s leadership position in 802.11a WLAN solutions. In addition, ORiNOCO gives us a blue-chip strategic alliance portfolio as well as industry leadership in the growing WLAN public access “hot spot’ market.”

Agere and Proxim have also agreed to enter into a three-year strategic supply agreement under which Agere will provide chips, modules and cards to Proxim, a license agreement for Agere technology used in the ORiNOCO business and a broad patent cross-license agreement for their respective patent portfolios including settlement of the pending patent-related litigation between the two companies. Agere’s new strategic supply agreement with Proxim represents a new engagement with a leading wireless LAN equipment provider.

Agere developed key technology that led to the evolution of 802.11, and today is the leading provider of wireless data solutions to all of the world’s major PC makers. The company will continue to provide wireless data chips, modules and cards for this market segment. Going forward, Agere intends to deliver Wi-Fi components that will help reduce costs for customers so that they can deploy this technology in a wide range of high-volume computing, networking and entertainment markets.

“The sale will allow us to strengthen our relationships with key customers and sharpen our strategic focus on our core Wi-Fi chip business,” said Ron Black, executive vice president of Agere’s Client Systems Group. “Our Wi-Fi components are fundamental to meeting the growing demand for increased wireless data connectivity. Today’s action is a solid step forward in realizing our vision for ubiquitous, wireless broadband access at home, at work, and on the go.”
