AGREEMENT AND PLAN OF MERGER, dated as of February 9, 2009 (this “Agreement”), by and among CSR plc, a company organized under the laws of England and Wales (“Parent”), ▇▇▇▇▇▇▇ Acquisition Sub, Inc., a Delaware corporation that is a direct, wholly-owned subsidiary of Parent (“Merger Sub”), and SiRF Technology Holdings, Inc., a Delaware corporation (the “Company”).

The date on which the Closing occurs is referred to as the “Closing Date”.

The Merger shall become effective when the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such other subsequent date or time as Parent and the Company may agree and specify in the Certificate of Merger in accordance with the DGCL (the “Effective Time”).

Section 1.4 Effects of the Merger. The Merger shall have the effects set forth in Section 259 of the DGCL.

Section 1.5 Certificate of Incorporation.

Section 1.6 Bylaws. The bylaws of Merger Sub in effect immediately prior to the Effective Time shall be, from and after the Effective Time, the bylaws of the Surviving Corporation (the “Surviving Bylaws”) until amended as provided in the Surviving Charter, in the Surviving Bylaws or by applicable Laws.

Section 1.9 Head Office. The head office of the Company immediately prior to the Effective Time will be the head office of the Surviving Corporation immediately following the Effective Time.

ARTICLE II

EFFECT OF THE MERGER ON CAPITAL STOCK;

EXCHANGE OF CERTIFICATES

Section 2.1 Conversion of Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holder of any shares of capital stock of Merger Sub or the Company:

(a) Conversion of Merger Sub Capital Stock. Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and non-assessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Parent-Owned Stock. Each share of Company Common Stock owned by the Company or by Parent or any of its wholly-owned Subsidiaries immediately prior to the Effective Time (collectively, the “Cancelled Shares”) shall be canceled automatically and shall cease to exist, and no Parent Ordinary Shares or other consideration shall be paid in exchange for those Excluded Shares. Each share of Company Common Stock owned by any wholly-owned Subsidiary of the Company immediately prior to the Effective Time (collectively with the Cancelled Shares, the “Excluded Shares”) shall remain outstanding.

(i) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares, if any) shall be converted into the right to receive 0.741 (the “Exchange Ratio”) fully paid Parent Ordinary Share, subject to (A) the anti-dilution adjustments provided in Section 2.2 and (B) the payment of cash in lieu of fractional Parent Ordinary Shares as provided in Section 2.3(f), and such Parent Ordinary Shares, when issued, shall be free from all Liens and rank pari passu in all respects with the Parent Ordinary Shares then in issue.

(ii) All shares of Company Common Stock that have been converted into the right to receive Parent Ordinary Shares as provided in Section 2.1(c)(i) shall be canceled automatically and shall cease to exist, and the holders of certificates which immediately prior to the Effective Time represented those shares (“Company Certificates”) shall cease to have any rights with respect to those shares, other than the right to receive Parent Ordinary Shares and cash in lieu of fractional Parent Ordinary Shares as provided in this Section 2.1 and Section 2.3 upon surrender of Company Certificates in accordance with this Article II, including Section 2.3(c) (together, the “Merger Consideration”).

Section 2.2 Adjustments to Prevent Dilution. If, prior to the Effective Time, Parent or the Company changes the number of Parent Ordinary Shares or shares of Company Common Stock outstanding, in each case as a result of share dividends or other distributions payable in Parent Ordinary Shares or Company Common Stock or securities convertible or exchangeable into or exercisable for Parent Ordinary Shares or Company Common Stock or a share or stock split (including a reverse share or stock split), reclassification, combination or other similar change with respect to the Parent Ordinary Shares or the Company Common Stock, then the Exchange Ratio shall be equitably adjusted to eliminate the effects of that share or stock dividend, distribution, share or stock split, reclassification, combination or other change.

Section 2.3 Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Parent shall (i) select a bank or trust company, satisfactory to the Company in its reasonable discretion, to act as the exchange agent in the Merger (the “Exchange Agent”) and (ii) enter into an exchange agent agreement with the Exchange Agent, the terms and conditions of which are satisfactory to the Company in its reasonable discretion (the “Exchange Agent Agreement”). Unless and until the Parent Ordinary Shares are listed on a national securities exchange in the United States, the parties shall cooperate to cause the Exchange Agent, Parent’s registrar or other institution reasonably satisfactory to the parties to maintain at Parent’s expense from and after the Effective Time a facility to allow for deposit, custody and trading of Parent Ordinary Shares on the London Stock Exchange by former holders of Company Certificates, or Company Stock Options, RSUs and PSAs, including residents of the United States, and if such entity ceases to maintain such facility for any reason, Parent shall use its reasonable best efforts to cause another facility to be created to provide for the foregoing.

(b) Exchange Fund. As of the Effective Time, Parent shall (i) allot to each holder of Company Certificates such whole number of Parent Ordinary Shares as such holder is entitled to receive under Section 2.1(c) which allotment shall be conditional only upon compliance with Section 2.3(c)(ii), (ii) subject to Section 2.3(f)(ii), allot to the Exchange Agent the Excess Parent Shares, and (iii) deposit with the Exchange Agent, for the benefit of holders of Company Certificates, certificates representing such Parent Ordinary Shares and, if applicable, Excess Parent Shares (collectively, “Parent Certificates”). Notwithstanding Section 2.3(b)(i) above, the parties will endeavour to permit, to the extent reasonably practicable, allotment and issue of the Parent Ordinary Shares referred to in Section 2.3(b)(i) at the Effective Time to the Exchange Agent as nominee for the holders of Company Certificates at such time, in which case the transfer of legal title to the Parent Ordinary Shares to such holders shall be conditional only upon compliance by those holders with Section 2.3(c)(ii). Such Parent Ordinary Shares as are allotted to the holder of Company Certificates or as are allotted to the Exchange Agent as nominee for such holders and, if applicable, Excess Parent Shares, together with (i) any cash in lieu of fractional Parent Ordinary Shares to which holders of Company Certificates may be entitled under Section 2.3(f) and (ii) any dividends or other distributions paid with respect to those shares and to which the holders of Company Certificates may be entitled under Section 2.3(d), are collectively referred to as the “Exchange Fund.”

(i) Letter of Transmittal. Promptly after the Effective Time, and in any event within 10 Business Days thereof, Parent shall cause the Exchange Agent to mail to each holder of record of a Company Certificate (A) a letter of transmittal in customary form, specifying that delivery shall be effected, and

risk of loss and title to the Company Certificates shall pass, only upon proper delivery of Company Certificates to the Exchange Agent and (B) instructions for surrendering Company Certificates.

(ii) Surrender of Company Certificates. Upon surrender of a Company Certificate for cancellation to the Exchange Agent, together with a duly executed letter of transmittal, the holder of that Company Certificate shall be entitled to receive in exchange therefor the number of whole Parent Ordinary Shares and cash in lieu of fractional Parent Ordinary Shares payable in respect of that Company Certificate less any required withholding of Taxes, which Parent shall issue and/or shall cause the Exchange Agent to issue (or, if applicable, transfer the legal title to, for nil consideration) and/or pay in accordance with the Exchange Agent Agreement and Parent’s register of members shall be updated accordingly. The Parent Ordinary Shares shall be issued in uncertificated form to such account as shall be specified in the completed letter of transmittal, unless a physical share certificate is requested or is otherwise required by applicable Laws, in which case Parent shall cause the Exchange Agent to send such Parent Certificates to such holder promptly in accordance with the Exchange Agent Agreement. Any Company Certificates so surrendered shall be canceled immediately. No interest shall accrue or be paid on any amount payable upon surrender of Company Certificates.

(iii) Unregistered Transferees. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, then the Merger Consideration may be issued and/or paid in accordance with this Section 2.3(c) to a person other than the person in whose name the Company Certificate so surrendered is registered if (A) such Company Certificate is properly endorsed or otherwise in proper form for transfer and (B) the person requesting such payment (1) pays any transfer or other Taxes required by reason of the transfer or (2) establishes to the reasonable satisfaction of Parent and the Exchange Agent that such Taxes have been paid or are not applicable.

(iv) No Other Rights. Until surrendered in accordance with this Section 2.3(c), each Company Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the aggregate Merger Consideration payable in respect of the shares represented by such Company Certificate. The Merger Consideration issued or paid upon the surrender of any Company Certificate will be deemed to have been issued or paid in full satisfaction of all rights pertaining to that Company Certificate and the shares of Company Common Stock formerly represented by it.

(d) Distributions with Respect to Unexchanged Shares. No dividends or other distributions payable with respect to Parent Ordinary Shares that have a record date after the Effective Time shall be paid to a holder of an unsurrendered Company Certificate until that Company Certificate is properly surrendered in accordance with this Article II. Subject to applicable Laws, following the proper surrender of any such Company Certificate, there shall be issued or paid to the Person to whom the Parent Certificate is issued in exchange therefor, without interest, (i) at the time of such surrender, the dividends or other distributions payable (if any) with respect to the Parent Ordinary Shares represented by that Parent Certificate that have a record date after the Effective Time and a payment date on or prior to the date of issuance of that Parent Certificate and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Parent Ordinary Shares that have a record date after the Effective Time and a payment date after the date of issuance of that Parent Certificate.

(e) No Further Transfers. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time.

(f) Fractional Shares.

(i) No certificates or scrip representing fractional Parent Ordinary Shares shall be issued upon the surrender of Company Certificates, and such fractional share interests will not entitle their owners to vote, to receive dividends or other distributions or to any other rights of a shareholder of Parent. Each holder of Company Certificates who would otherwise have been entitled to receive a fraction of a Parent Ordinary Share under this Article II (after taking into account all Company Certificates

delivered by such holder) shall receive from the Exchange Agent, in accordance with the provisions of this Article II, a cash payment in United States dollars in lieu of such fractional share interest either (A) representing that holder’s proportionate interest in the net proceeds from the sale by the Exchange Agent in one or more transactions of the aggregate of the fractional Parent Ordinary Shares which would otherwise have been issued under this Article II (the “Excess Parent Shares”) or (B) in accordance with Section 2.3(f)(ii). The sale of the Excess Parent Shares shall be (A) executed on the London Stock Exchange and (B) made at such times, in such manner and on such terms as the Exchange Agent shall determine in its reasonable discretion. Funds received from the sale of the Excess Parent Shares denominated in pounds sterling shall be exchanged for United States dollars at the best rate of exchange reasonably available to the Exchange Agent on or immediately after the date of such sale. Until the net proceeds of such sale or sales have been distributed to the holders of Company Certificates in accordance with this Section 2.3, the Exchange Agent shall hold the net proceeds in trust (the “Exchange Trust”) for those holders. All commissions, fees, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with the sale of the Excess Parent Shares shall be paid by Parent and the Surviving Corporation. As soon as practicable after the determination of the amount of cash to be paid to holders of Company Certificates in lieu of fractional Parent Ordinary Shares, the Exchange Agent shall make that amount available to those holders, without interest. The Exchange Agent shall determine the portion of the net proceeds to which each holder of Company Certificates shall be entitled by multiplying the aggregate amount of the net proceeds by a fraction of which (1) the numerator is the amount of the fractional share interest to which such holder of Company Certificates is entitled (after taking into account all Company Certificates delivered by such holder) and (2) the denominator is the aggregate amount of fractional share interests to which all holders of Company Certificates are entitled.

(ii) Notwithstanding the provisions of Section 2.3(f)(i), Parent may elect, at its option exercised prior to the Effective Time, to pay to the Exchange Agent an amount in cash in United States dollars, to be deposited on the first Business Day following the Effective Time, sufficient for the Exchange Agent to pay each holder of Company Certificates an amount in cash equal to the product obtained by multiplying (A) the fraction of a Parent Ordinary Share to which such holder would otherwise have been entitled by (B) the closing price for a Parent Ordinary Share on the London Stock Exchange on the first Business Day immediately following the Effective Time. In such event, all references in this Agreement to the net proceeds from the sale of the Excess Parent Shares and similar references shall be deemed to refer to the payments calculated in the manner set forth in this Section 2.3(f)(ii).

(g) Required Withholding. Parent, the Company, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any cash payments made pursuant to this Agreement such amounts as they may be required to deduct and withhold from such payment under any applicable tax Laws. If Parent, the Company, the Surviving Corporation or the Exchange Agent, as the case may be, deducts or withholds any such amounts, such amounts shall be treated for all purposes as having been paid to the Person in respect of whom Parent, the Company, the Surviving Corporation or the Exchange Agent, as the case may be, made such deduction and withholding.

(h) Termination of Exchange Fund and Exchange Trust. Any portion of the Exchange Fund or the Exchange Trust that remains unclaimed by the holders of Company Certificates one year after the Effective Time shall be delivered by the Exchange Agent to Parent upon demand. Any holder of Company Certificates who has not complied with this Article II shall look thereafter only to Parent for payment of the Merger Consideration.

(i) No Liability. None of Parent, the Surviving Corporation or the Exchange Agent shall be liable to any holder of Company Certificates for any Merger Consideration properly delivered to a public official under any applicable abandoned property, escheat or similar Laws.

(j) Lost, Stolen or Destroyed Certificates.

The exercise price per share of such Converted Stock Option shall be equal to (x) the aggregate exercise price of such Company Stock Option immediately prior to the Effective Time divided by (y) the number of Parent Ordinary Shares for which such Converted Stock Option shall be exercisable, as determined in accordance with the prior sentence, rounded up to the nearest cent. “Company Option Plans” means the 1995 Stock Plan, the 2004 Stock Incentive Plan, the TrueSpan 2004 Stock Incentive Plan and the Centrality 1999 Stock Plan.

(b) As of the conversion pursuant to Section 2.4(a), each Converted Stock Option shall have, and be subject to, the same terms and conditions set forth in the applicable Company Option Plan and the option agreement pursuant to which the corresponding Company Stock Option was granted, as in effect immediately prior to the Effective Time) except as otherwise provided herein.

(c) To the extent that any Company Stock Option constituted an “incentive stock option” (within the meaning of Section 422 of the Code) immediately prior to the Effective Time, such Company Stock Option shall continue to qualify as an “incentive stock option” to the maximum extent permitted by Section 422 of the Code.

(d) No later than five Business Days following the Effective Time, Parent shall file a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the issuance of Parent Ordinary Shares upon exercise of all Converted Stock Options and shall use commercially reasonable efforts to maintain the effectiveness of such registration statement(s) (and maintain the current status of any prospectus contained therein) for so long as any Converted Stock Options remain outstanding.

(e) As of the Effective Time, each restricted stock unit with respect to shares of Company Common Stock granted under a Company Option Plan that is outstanding immediately prior to the Effective Time (each, an “RSU”) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into a restricted stock unit, on the same terms and conditions (including applicable vesting requirements and deferral provisions) as applied to each such RSU immediately prior to the Effective Time, with respect to the number of Parent Ordinary Shares that is equal to the number of shares of Company Common Stock subject to the RSU immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded to the nearest whole share) (a “Parent RSU”). As of the Effective Time, each Parent RSU shall have, and be subject to, the same terms and conditions set forth in the applicable Company Option Plan and the RSU agreement pursuant to which the corresponding RSU was granted, as in effect immediately prior to the Effective Time) except as otherwise provided herein.

(f) [Reserved]

(g) Each outstanding right to purchase shares of Company Common Stock under any outstanding offering period as of the date of this Agreement under the 2004 Employee Stock Purchase Plan (the “ESPP”) shall terminate not later than the day immediately prior to the day on which occurs the Effective Time, provided that the Company may permit each participant in the ESPP to purchase from the Company as many whole shares of Company Common Stock as the balance of the participant’s account will allow, at

the applicable price determined under the terms of the ESPP for each such outstanding offering period, using such date as the final purchase date for such offering period, and any amounts remaining in any participant’s account after any such purchase will be refunded to the participant.

Section 2.5 Appraisal Rights. Unless the Parent Ordinary Shares are listed on a “national securities exchange” (as such term is used in the DGCL) at the Effective Time (a “Timely Listing”), any provision of this Agreement to the contrary notwithstanding, all shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time (other than Cancelled Shares) and that are held by holders who have demanded and perfected their right to dissent from the Merger and to be paid the fair value of such shares in accordance with the DGCL and, as of the Effective Time, have not effectively withdrawn or lost such dissenters’ rights (such shares, if any, the “Dissenting Shares”) shall not be converted into or represent the right to receive the Merger Consideration, but instead holders of such Dissenting Shares shall be entitled only to such rights as are granted by the DGCL. If any holder of shares of Company Common Stock who demands dissenters’ rights under the DGCL with respect to such holder’s shares effectively withdraws or loses such rights (whether through failure to perfect or otherwise) in accordance with the DGCL, then, as of the Effective Time or the occurrence of such event, whichever occurs later, such holder’s shares shall automatically be converted into and represent only the right to receive the Merger Consideration in accordance with this Article II, without interest thereon, upon surrender of the certificate or certificates formerly representing such shares. The Company shall give Parent (i) prompt written notice of any notice of intent to demand appraisal of any Dissenting Shares that may be received by the Company, withdrawals of such notices or demands, and any other instruments relating to stockholders’ rights of appraisal that are served pursuant to the DGCL and received by the Company and (ii) the opportunity to participate in all negotiations and proceedings with respect to such notices and demands. The Company shall not, except with the prior written consent of Parent (which consent shall not be unreasonably withheld), settle, or offer to agree to settle, any such demands. In the event of a Timely Listing, no appraisal rights will be available to the stockholders of the Company in connection with the Merger.

The Company shall promptly inform its Representatives of the Company’s obligations under this Section 5.4. The Company agrees that any violation of the provisions of this Section 5.4 by any Representative of the Company or any of its Subsidiaries at the direction or with the consent of the Company or any of its Subsidiaries shall be deemed to be a breach of this Section 5.4 by the Company.

(ii) withdraw, modify or amend the Company Board Recommendation in a manner adverse to Parent if the board of directors of the Company has (A) after consultation with legal counsel, determined in good faith that failure to take such action would be inconsistent with its duties to the stockholders of the Company and (B) where such withdrawal, modification or amendment does not involve a Company Takeover Proposal, provided Parent with at least two Business Days’ prior written notice of its intention to take such action; and/or

(iii) recommend such Company Takeover Proposal if (A) the board of directors of the Company has determined in good faith, after consultation with the Company Financial Advisor, that such Company Takeover Proposal constitutes a Superior Proposal and (B) the Company has provided Parent with three Business Days prior written notice of its board of directors’ intention to take such action (it being understood that such three Business Day period will not apply if the three Business Day period (or two Business Day period in respect of an amendment) provided for in Section 7.4(a)(iii) is applicable).

If Parent is unable to obtain, or unable to so cause to be obtained, the insurance described in the prior sentence for an amount less than or equal to the Maximum Premium, it shall instead obtain, or cause the Surviving Corporation to obtain, as much comparable insurance as possible for an annual premium equal to the Maximum Premium.

The parties hereto acknowledge that (i) the agreements contained in this Section 7.5 are an integral part of the transactions contemplated by this Agreement and (ii) without these agreements, the parties would not have entered into this Agreement. Accordingly, if either party fails promptly to pay any amount payable by it pursuant to this Section 7.5, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the payment set forth in this Section 7.5, the non-paying party shall pay to the other party its costs and expenses (including attorneys’ fees, charges and

This Agreement may not be amended except by an instrument in writing signed by each of the parties to this Agreement.

Section 7.7 Extension; Waiver. At any time prior to the Effective Time, Parent and Merger Sub, on the one hand, and the Company, on the other hand, may (a) extend the time for the performance of any of the obligations of the other party, (b) waive any inaccuracies in the representations and warranties of the other party contained in this Agreement or in any document delivered under this Agreement or, (c) subject to applicable Laws, waive compliance with any of the covenants or conditions contained in this Agreement. Any agreement on the part of a party to any extension or waiver shall be valid only if set forth in an instrument in writing signed by such party. The failure or delay of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.
