CSR plc Response to Zoran Corporation Board Changes

CSR PLC (“CSR”: LSE: CSR.L or the “Company”) provides the following update on its merger (the “Merger”) with Zoran Corporation (“Zoran”: NASDAQ: ZRAN):

On 4 March 2011 Zoran shareholder Ramius Value and Opportunity Advisors LLC (“Ramius”) announced that it had delivered consents from the holders of a majority of the shares of Zoran in order to replace three of the seven directors of Zoran with nominees of Ramius.

At the time of signing the definitive merger agreement with Zoran, CSR was aware of the Ramius consent solicitation and the possible changes in Zoran’s board of directors.

CSR does not expect any material change in the business of Zoran as a result of the consent process. With that process now concluded, Zoran management will be able to focus on its customers, running the business, and taking the actions necessary to complete the merger between CSR and Zoran.

The merger agreement between CSR and Zoran remains in full force and effect and CSR continues to expect completion of the merger, subject to shareholder approval and other customary closing conditions, during the second quarter of 2011.
