LEGERITY to acquire voice interface solutions analog line card integrated circuit business from AGERE SYSTEMS

AUSTIN, Texas and ALLENTOWN, Pa.- June 26, 2002 -- Legerity, Inc., a leading supplier of integrated circuits for voice network access and voice-over-broadband applications, and Agere Systems (NYSE: AGR.A, AGR.B), the world leader in communications components, today announced Legerity will acquire Agere’s analog line card integrated circuit business for $70 million in cash.

The transaction includes the products, technology and intellectual property related to Agere’s analog line card business, which provides integrated circuits, or microchips, used in telephone network equipment. The sale will allow Legerity to extend its expertise in this market, and enables Agere to focus its resources on developing advanced components that form the building blocks for next-generation network applications.

As part of the transaction, approximately 50 employees of Agere’s analog line card business will join Legerity. Agere and Legerity anticipate closing the transaction in the third calendar quarter of 2002, subject to regulatory approval and other customary closing conditions.

“Legerity is a recognized leader in voice network access and voice over broadband semiconductor solutions. This agreement will provide Agere customers and business partners strong confidence in the continued availability and future extensions of these product families,“ stated Ron Van Dell, president and chief executive officer of Legerity. “This business is very complementary to our current product offerings. It enhances Legerity’s opportunities in key growth markets in Asia while simultaneously adding a world-class team to Legerity,” added Van Dell.

Through a transitional supply agreement, Agere will supply chips for Legerity through early 2003 to ensure seamless service to customers. Agere currently manufactures the majority of these chips at its Reading, Pa., facility.

“Today’s announcement is another step in our continuing efforts to streamline our business," said Sohail Khan, executive vice president of Agere's Infrastructure Systems Group. "This sale is consistent with our long-term strategy to develop component and subsystem networking solutions aimed at enabling high-speed, multi-service networks that will increasingly integrate voice, data and video capabilities.”

In the last several months, Agere has taken a number of actions to sharpen its strategic focus. In December, the company sold its field-programmable gate array (FPGA) business and last week sold its Wireless LAN equipment business.
