NATIONAL SEMICONDUCTOR ELECTS E. FLOYD KVAMME TO BOARD OF DIRECTORS

May 20, 1998 -- National Semiconductor Corporation today announced the election of E. Floyd Kvamme to its Board of Directors.

Since March of 1984 Kvamme has been a partner at Kleiner Perkins Caufield & Byers, a high technology venture capital firm located in Menlo Park, California. He is responsible for the development of high technology companies from early start-up to the publicly traded phase.

Brian L. Halla, chairman, president and CEO of National Semiconductor said Kvamme represents a valuable addition to the company's board of directors.

"Floyd Kvamme is one of the leaders that built Silicon Valley, and he brings with him a unique mix of understanding of technology, marketing and semiconductor operational experience," Halla said.

Kvamme was one of five members of the management team formed by Charles E. Sporck in 1967 when Sporck took over as president of National and relocated its headquarters to Santa Clara, California. In 1979, Kvamme became the president of National's computer subsidiary, National Advanced Systems.

In 1982 he left National to become Executive Vice President of Sales and Marketing for Apple Computer, a position he held until entering the venture capital field in 1984.

Kvamme currently serves on the boards of Brio Technology, Harmonic Lightwaves, Photon Dynamics, Power Integrations, Prism Solutions, Triquint Semiconductor, and some private companies. He has two degrees in electrical engineering, a bachelor's degree from the University of California at Berkeley and a master's degree from Syracuse University.
