September 23, 1999 - Boca Research, Inc.? (Nasdaq:BOCI) and National Semiconductor? Corporation today announced the signing of a definitive agreement whereby National Semiconductor will purchase 691,085 newly issued shares, or approximately 6% of the currently outstanding Boca Research common stock, at a purchase price of $7.235 per share, for an aggregate purchase price of approximately $5.0 million in cash.

"We are excited to be a technology partner with Boca Research," said Brian Halla, chairman, chief executive officer, and president of National Semiconductor. "Our information appliance thrust and our Geode family of products are enabling Boca Research to bring consumers new types of information access devices beyond the traditional desktop PC.
