WHEREAS, substantially concurrently with the execution and delivery of this Agreement, Tencent will submit a preliminary non-binding proposal letter (the “Proposal”) to the board of directors of Sogou Inc., an exempted company with limited liability incorporated under the laws of the Cayman Islands and listed on the New York Stock Exchange (the “Company”), to acquire all of the outstanding Class A ordinary shares (including Class A ordinary shares represented by American depositary shares) and Class B ordinary shares of the Company (collectively, the “Ordinary Shares”) not already owned by Tencent or its Affiliates (as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended), for US$9 in cash per Class A or Class B ordinary share (as the same may be revised from time to time and set forth in definitive agreements between Tencent and the Company, the “Transaction”).

WHEREAS, as of the date hereof, Mr. Zhang is the beneficial owner of 24,686,863 Class A ordinary shares of the Company (such Ordinary Shares, together with any Ordinary Shares or other voting share capital of the Company with respect to which Mr. Zhang acquires beneficial ownership after the date hereof, the “Covered Shares”).

WHEREAS, as a condition and inducement to the willingness of Tencent to submit the Proposal and pursue the Transaction, Mr. Zhang agrees (in his capacity as the beneficial owner of the Covered Shares, and not in his capacity as an officer and director of the Company and Sohu.com Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands and listed on NASDAQ (“Sohu”), or of any controlled Affiliate of the Company or Sohu, nor in his capacity as the beneficial owner of ordinary shares of Sohu) to support the Transaction and sell his Covered Shares to Tencent or its Affiliates upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the Parties agree as follows:

1.       Mr. Zhang agrees that he shall and shall cause his Affiliates (which for purposes of this Agreement will not include the Company, Sohu, or any controlled Affiliate of the Company or Sohu) to (a) work with Tencent to support and facilitate the Transaction; (b) at any annual or extraordinary general meeting of the shareholders of the Company or in connection with any written consent of the shareholders of the Company, vote or deliver a written consent covering all of his Covered Shares in favor of the approval, adoption and authorization of the Transaction; and (c) sell (by merger, share transfer or otherwise) all the Covered Shares to Tencent or its Affiliates prior to or in the Transaction at the price per Ordinary Share to be paid to the other shareholders of the Company in the Transaction.

2.       Mr. Zhang irrevocably and unconditionally waives, and agrees to cause to be waived and to prevent the exercise of, any dissenters’ rights, rights of appraisal and any similar rights relating to the Transaction that he or any other person may have by virtue of, or with respect to, any of his Covered Shares.
