SAN FRANCISCO, Dec. 29 -- BEI Technologies Inc. announced last week it has acquired OpticNet as a wholly owned subsidiary of the company. OpticNet, based in Hayward, Calif., makes optical components used in communications equipment. BEI and its acquisition subsidiary entered into a definitive merger agreement earlier this year to acquire OpticNet at a price equal to $0.04 per share of 5,367,235 outstanding shares of common stock. Each share not accepted for purchase in the offer was converted into the right to receive $0.04 in cash, without interest, in the merger.
