Ladies and Gentlemen:

Gongqingcheng Wujiang Xingyao Investment Management Partnership (Limited Partnership) (the “Sponsor”) is pleased to offer this commitment with respect to the purchase of certain equity interests of Beijing Wuxing Rongcheng Technology Ltd., a limited liability company incorporated under the laws of the People’s Republic of China (“Holdco”). Holdco has been formed for purposes of acquiring KongZhong Corporation (the “Company”) pursuant to an Agreement and Plan of Merger (as amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), dated as of the date hereof, by and among the Company, Linkedsee Limited (“Parent”) and Wiseman International Limited (“Merger Sub”) on the terms and subject to the conditions set forth in the Merger Agreement (the “Transaction”). Each capitalized term used and not defined herein shall have the meaning ascribed thereto in the Merger Agreement. This letter agreement (this “Agreement”) is being delivered together with substantially identical commitment letters, dated as of the date hereof, from Mr. Leilei Wang and Hexie Chengzhang Phase II (Yiwu) Investment Center (Limited Partnership) (the “Other Sponsors”) to Holdco setting forth their respective commitments to purchase, on the terms and subject to the conditions set forth therein, certain equity interests of Holdco (the “Other Commitment Letters”).

1.Commitment. The Sponsor hereby commits to purchase equity securities of Holdco at or prior to the Effective Time for an aggregate amount of RMB equivalent to US$20,000,000 (and the RMB equivalents of U.S. dollars shall be determined using the prevailing exchange rate notified by Parent to the Sponsor at least three (3) Business Days prior to funding), on the terms and subject to the conditions specified herein, which commitment, together with the commitments by the Other Sponsors under the Other Commitment Letters, is to be used by Holdco and/or Parent solely for the purpose of (i) funding a portion of the Merger Consideration required to be paid by Parent to consummate the Transactions pursuant to and in accordance with the Merger Agreement and (ii) payment of a portion of the fees and expenses in connection with the Transaction (such commitment, the “Commitment”). The Sponsor will not have any obligation under any circumstances to contribute, directly or indirectly, any capital or money that would be more than the amount of the Commitment to Holdco, Parent, Merger Sub or any other person pursuant to the terms of this Agreement. In the event that Holdco and/or Parent does not require an amount equal to the sum of the Commitment plus the amount of the equity commitments of the Other Sponsors under the Other Commitment Letters in order to consummate the Merger, the amount of the Commitment to be funded under this Agreement and the amount of the equity commitment of each Other Sponsor to be funded under its respective Other Commitment Letter shall be reduced by Holdco on a pro rata basis, to the amount that would be sufficient, in combination with the other financing
