SUNNYVALE, Calif.--(BUSINESS WIRE)--June 27, 2000

ADAPTIVE BROADBAND CORPORATION (Nasdaq:ADAP) announced that it has entered into an agreement with Vislink plc (formerly Silvermines Group plc) to sell its Microwave Radio Communications division for $19.2 million in cash. Vislink is a UK-based manufacturer of broadcast and telecommunications equipment. The company announced recently that it had entered into agreements to sell two other divisions. Agreements have been reached with Comtech Telecommunications Corp. to sell the EFData satellite modem division for a total transaction value of $67.8 million, and with Mosely Associates to sell the Microwave Data Systems (MDS) division for $42.0 million. It is planned that the results of all three transactions will be combined and reported. The company expects to recognize a net book gain on the combined divestitures and to retain substantially all of the cash due to the company's deferred income tax benefits.

The MRC transaction, which is targeted to close in July 2000, is subject to normal conditions, including governmental reviews and approval by the shareholders of Vislink. MRC designs, develops and manufactures a wide range of microwave radio products for the television broadcast and electronic newsgathering markets.

Next Step in Strategic Plan: Expanding Market Coverage

"With the divestiture of our three legacy businesses nearly behind us, we can focus on continuing to form the types of strategic partnerships we need to maintain our lead in the emerging wireless broadband market. Continuing to develop distribution channels is paramount to addressing a global market of this enormity. We are pleased with our progress to date in achieving these alliances and look forward to the further expansion of our market coverage in the near future," commented Donna S. Birks, executive vice president and chief financial officer of Adaptive Broadband.
