LaFox, IL, Monday, April 9, 2007: Richardson Electronics, Ltd. (NASDAQ: RELL) today announced that it has signed a definitive agreement to sell Burtek Systems Corp. and the Security Systems Division (SSD) to Honeywell, which will then integrate it into its ADI security distribution business after closing, for $80 million in cash, subject to post closing adjustments and regulatory review. Burtek/SSD is a distributor of low voltage products for commercial and residential audio, burglar and fire alarm, CCTV, access control, sound and data/network communications.

Burtek/SSD has been a major contributor to the success of Richardson Electronics. We are extremely pleased with the future of the business as part of Honeywell,” said Edward J.
