CP CLARE acquires TELTONE TECHNOLOGY for new network interfacing solutions

Beverly, MA and Bothell, WA - Aug. 10, 2000 -- CP Clare Corporation (NASDAQ: CPCL; d/b/a Clare), a recognized leader in high-performance mixed-signal integrated circuits (IC) and discrete semiconductor components, today announced it has agreed to acquire the integrated circuit business unit of Teltone Corporation, (OTCBB: TTNC) a leading provider of remote voice solutions and telecom equipment. The acquisition is expected to close August 25, 2000 and will be accounted for under the purchase method of accounting. Other terms were not disclosed.

Tone generation and detection functions are fundamental for many new network interface applications including cellular and Internet phones, high-speed modems, central office switches, and other equipment that connects to the telephone network. The acquisition gives Clare's customers access to a portfolio of industry-standard tone signaling products as well as a family of proprietary advanced call progress and call detection IC's. The acquisition augments Clare's offering of mixed-signal IC products that support applications at the edge of the network.

"New applications such as Voice over Internet Protocol (VoIP), home gateways, Voice over DSL, Bluetooth enabled cordless phones etc., are driving strong demand for tone generation and call progress IC products. We expect this demand to continue to grow," said Arthur R. Buckland, Clare President and CEO. "This accretive acquisition complements our existing product lines and expands our IC offering to our target markets that are developing and producing the next generation of voice based products that interface to the network.

"Teltone's tone generation and detection IC products have a strong heritage of reliability and network compatibility. This pre-packaged expertise allows system designers one of the fastest and most reliable paths from system specification to system production," said Richard Soshea, President and CEO, Teltone Corporation. "Teltone's strategic direction has been refocused over the past few months and the IC business, while significant, is no longer part of the new direction. Our sale of this business segment allows Teltone to focus on its rapidly growing remote voice and telecom equipment segments. The sale was facilitated by Alliant Partners, who had been retained earlier this year to help Teltone maximize shareholder value in each of its business segments."
