~~Forward~~This ~~Looking~~communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 which represent the current expectations and beliefs of management of SiRF concerning the proposed Merger and other future events and their potential effects on SiRF, including, but not limited to, statements relating to anticipated financial and operating results, each company’s plans, objectives, expectations and intentions, cost savings and other statements, including words such as “anticipate,” “believe,” “plan,” “estimate,” “expect,” “intend,” “will,” “should,” “may,” and other similar expressions. Such statements are based upon the current beliefs and expectations of our management, are not guarantees of future results and are subject to a significant number of risks and uncertainties. Actual results may differ materially from the results anticipated in these forward looking statements. The risks and uncertainties we face include, without limitation: the ability to satisfy conditions to the transaction on the proposed terms and timeframe; the possibility that the Merger does not close when expected or at all; the ability to realize the expected cost and revenue synergies from the Merger in the amounts or in the timeframe anticipated; the ability to integrate SiRF’s businesses into those of CSR’s in a timely and cost-efficient manner; the development of the markets for SiRF’s and CSR’s products, the combined company’s ability to develop and market a multifunction radio product containing our GPS-based location technology and CSR’s Bluetooth technology in a timely fashion; weak current economic conditions, uncertain future economic conditions, and the difficulty in predicting sales, even in the short-term; factors affecting the quarterly results of SiRF, CSR and the combined Company, sales cycles, price reductions, dependence on and qualification of foundries to manufacture the products of SiRF, CSR and the combined company, production capacity, the ability to adequately forecast demand, customer relationships, the ability of SiRF, CSR and the combined company to compete successfully, our product warranties, the impact of legal proceedings, the impact of the intellectual property indemnification practices of SiRF, CSR and the combined company; and other risks and uncertainties, including those detailed from time to time in our periodic reports filed with the Securities and Exchange Commission, including our Current Reports on Form 8-K, Quarterly Reports on Form 10-Q and Annual Report on Form 10-K. In particular, we refer you to the sections entitled “RISK FACTORS” of the Proxy Statement, dated June 2, 2009, and “Item 1A. RISK FACTORS” of our Quarterly Report on Form 10-Q for the quarter ended March 28, 2009 filed with the Securities and Exchange Commission, for additional information regarding the risks and uncertainties discussed above as well as additional risks and uncertainties that may affect our actual results. The forward-looking statements in this communication are qualified by these risk factors. Each statement speaks only as of the date of this communication (or any earlier date indicated in this communication) and SiRF undertakes no obligation to update or revise any forward-looking statements to reflect subsequent events or circumstances. Investors, potential investors and others should give careful consideration to these risks and uncertainties.

Except for the historical information contained herein, the matters set forth in this press release, including, but not limited to, statements regarding the entry into the United States of certain redesigned SiRF devices and products containing those devices, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “to” and “may” and similar expressions are intended to identify forward-looking statements. Although SiRF may be able to enter the approved redesigned GPS devices and products containing those devices into the United States in the ordinary course of business, SiRF cannot guarantee the outcome or anticipate the benefits of such activity. These statements are not guarantees of future performance and should not be considered as an indication of future performance. SiRF’s ability to enter devices and products into the United States has inherent risks and uncertainties, including, among others, the risk that we may not realize any anticipated benefit from the United States Customs and Border Protection ruling, market demand and acceptance for our redesigned products and those of our customers, risks associated with the semiconductor industry, risks of ongoing or additional litigation with Broadcom, including further attempts to pursue enforcement proceedings with the ITC against SiRF based on the redesigned chips and products or new proceedings, and other risks and uncertainties discussed in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 28, 2009 and from time to time in SiRF’s SEC reports. These forward-looking statements speak only as of the date hereof. We do not undertake any obligation to update forward-looking statements.
