Provisional Deposit of Provisional Shares

Ladies & Gentlemen:

Reference is made to
(i) the Deposit Agreement, dated as of June 29, 2007 (the Deposit Agreement), by and among Spreadtrum Communications, Inc., a company organized under the laws of the Cayman Islands (the Company),
Citibank, N.A., as Depositary (the Depositary), and the Holders and Beneficial Owners of American Depositary Shares (the ADSs) issued thereunder, and (ii) the Letter Agreement, dated as of May 22, 2008
(the 2008 Letter Agreement), by and between the Company and the Depositary, which supplements the Deposit Agreement on the subject of the provisional deposit of Provisional Shares (as defined in the Letter Agreement).
All capitalized terms used, but not otherwise defined herein, shall have the meaning assigned thereto in the 2008 Letter Agreement or, if not defined in the 2008 Letter Agreement, in the Deposit Agreement.

The Company hereby informs the Depositary that, as of January 26, 2009, Merrill Lynch, Pierce, Fenner & Smith will be the plan record
keeper for the Plans.

In furtherance of the foregoing, the Company and the Depositary agree to amend the 2008 Letter Agreement as follows:

1. The Depositary shall, in respect of the Provisional Shares, be authorized to rely and act upon the written instructions signed and
delivered on behalf of the Company by (i) one or more of the Companys officers and employees designated from time to time by the Company to the Depositary as authorized persons, and (ii) on, or after January 26,
2009, one of the authorized persons for Merrill Lynch, Pierce, Fenner & Smith (and designated as such by Merrill Lynch, Pierce, Fenner & Smith), the plan record keeper for each of the Plans, including instructions so
delivered in electronic form.

2. In the event that, in determining the rights and obligations of parties to the Deposit Agreement (as
supplemented by the 2008 Letter Agreement and this letter agreement) with respect to any Provisional Shares, any conflict arises between (a) the terms of the 2008 Letter Agreement and (b) the terms hereof, the terms and conditions set
forth herein shall be controlling.



---

3. The ADS Issuance Instructions to be received on or after January 26, 2009 shall be substantially
in the form of Exhibit A attached hereto.

The terms of this letter agreement amend the 2008 Letter Agreement, which supplements the
Deposit Agreement, and are not intended to materially prejudice any substantial existing rights of Holders or Beneficial Owners of ADSs and, as a result, notice is not required to be given of the terms hereof to Holders of ADSs under the Deposit
Agreement. The Company and the Depositary shall make reference to the terms of this letter agreement in, and attach an executed copy hereof to, the next Registration Statement on Form F-6 filing (including without limitation any amendatory filings)
made with the U.S. Securities and Exchange Commission in respect of the ADSs.

The Company acknowledges and agrees that the indemnification
provisions of the Deposit Agreement shall apply to any acts performed or omitted by the Depositary pursuant to the terms of the 2008 Letter Agreement as amended by this letter agreement, including, without limitation, the acceptance and maintenance
of Provisional Shares on provisional deposit and the issuance and delivery of ADSs upon the terms contemplated in the 2008 Letter Agreement as amended by this letter agreement.

This letter agreement shall be interpreted in accordance with, and all of the rights and obligations under this letter agreement shall be governed by,
the laws of the State of New York without regard to the principles of conflicts of law thereof.
