 Upon amicable consultation, the Parties amend relevant provisions of the Agreement as follows:

  

	1.	 Amendment to Long-term Business Cooperation 



 

	 	1.1	 The Parties agree that except for Clause 1(2) on the long-term business cooperation of the
Agreement, the validity period of the other provisions of Clause 1 of the Agreement shall be extended to September 15th, 2023. 


  

	2.	 Amendment to the Strategic Principles of Business Development and Resource Sharing



  

	 	2.1	 Tencent and Sohu agree that from September 16, 2018 to September 15, 2023
(“Cooperation Period”) respectively, if it sets any default general search engine in its products in the form of embedment or otherwise (different from
on-site/in-product search engine ), such default general search engine shall be the search engine powered by Sogou. For the purpose hereof, the Parties
clarify as follows: 


  

	 	(1)	 For the purpose of Clause 2.1 hereof, Tencent and Sohu will not deprive users of their
rights of choosing, at their discretion, search product services that compete with Sogou. 


  

	 	(2)	 General search engine means a search engine whose search contents are from public information on various
Internet websites that is available to third-party “Spider” program or from open database on various Internet websites; on-site/in-product search engine means
a search engine that only extracts information within the website or products (including public or non-public information) to retrieve and return results. 



 

	 	(3)	 The search function inside Weixin/WeChat is not the above-mentioned “general search engine ”, and is
not subject to the above provision that “such default general search engine shall be the search engine powered by Sogou”. However, from September 16, 2018 to September 15, 2019, under equivalent conditions and subject to
Tencent’s requirements for user experience, Sogou Search will be the preferred third-party search function to power such a Weixin/WeChat search function that allows Weixin/WeChat users to access Internet information outside
Weixin/WeChat for that period, and that the arrangement herein may be extended for additional successive one-year periods through September 2023.

and the other provisions of the Agreement shall remain fully effective.

	 	3.3	 Definition and Interpretation. Unless otherwise stated, the words used herein shall have the same
meanings set forth in the Agreement. 


  

	 	3.4	 Counterparts. This Supplemental Agreement may be made in multiple counterparts. All counterparts
