Other Events

On June 25, 2009, stockholders of SiRF Technology Holdings, Inc. (“SiRF”) voted at a special meeting to adopt the Agreement and Plan of Merger, dated as of February 9, 2009 (the “Merger Agreement”), by and among CSR plc (“CSR”), Shannon Acquisition Sub, Inc., a direct, wholly owned subsidiary of CSR (“Merger Sub”), and SiRF, pursuant to which Merger Sub will merge with and into SiRF, with SiRF surviving the merger as a direct, wholly owned subsidiary of CSR (the “Merger”).

Under the terms of the Merger Agreement, SiRF stockholders will receive 0.741 of a CSR ordinary share for each share of SiRF common stock they own at the closing of the Merger. The transactions contemplated by the Merger Agreement are expected to close on June 26, 2009, subject to customary closing conditions and the admission of CSR ordinary shares issuable to SiRF stockholders to the Official List of the United Kingdom Listing Authority.

The Merger Agreement was originally filed by SiRF with the Securities and Exchange Commission on February 10, 2009 as an exhibit to its Current Report on Form 8-K.
