 According to the Contract Law of the People’s Republic of China, the Parties hereto enter into this
contract regarding the copyright transfer of Tian Long Ba Bu Online Game Software v1.0 (the Registration Number of Computer Software Copyright: 2006SRBJ0800) after friendly consultations. 
  

	I.	The Content, Requirements and the Industrialization Development of Non-patent Technology: 

  

	 	(1)	Technology Content 

 The Tian Long Ba Bu Online Game is
recomposed based upon the martial arts novels authorized by Mr. Louis Cha. The Tian Long Ba Bu Online Game is a domestic online game with complete 2.5D figures and scenes all based upon independent research and development. The content of the
game is healthy and uplifting with the distinct characteristics of the local culture. 
 <Tian Long Ba Bu Online Game Software v1.0>
applied the scene editor especially developed by Party B which makes art and planning perfectly visible while designing the game. According to the nature of the three-dimensional characters in the Tian Long Ba Bu Online Game, Party B has also
developed all sorts of export plug-ins of data models, which make the actions of the game figures more smooth, realistic and colorful. In addition, the database of the software has applied cross-platform development, which could be used on either
MySQL of Linux or SQL-Server of Windows and could be accessed through the ODBC connection layer. 
  

	 	(2)	Technology Requirements 

  

	 	i.	High Efficient 3D Rendering Engine: The software adopts China’s leading 3D engine FairyLib, which can efficiently deal with all kinds of 3D and support bone action, flexible
terms, physical simulation, weather changes and so on, and bring the wonderful screens to the users. 

  

	 	ii.	Asymmetric Encryption Exchange Technology: The software with asymmetric encryption exchange technology and the encryption of the game’s messages with asymmetric exchange
technology can prevent third parties from intercepting the software and decrypting the game data package, which can protect the security of the messages. 

  

	 	iii.	Distributed Game Server Platform: The server program is calculated in a distributed manner, and the different scene maps are operated on different servers, which improve the
efficiency of the game’s operation. The server program can support tens of thousands of concurrent online users on a single server and provide good service quality to the users.

	 	iv.	Cross-platform Game System: The software under the cross-platform network engine of Party B can cause a single server to deal with thousands of connections, to effectively solve the
problems of cross-platform and to make the software operate stably either on the Windows system or the Linux system. The database could either use the SQL-Server of Windows as its database system or MySQL of Linux as its database system.

  

	 	v.	Efficient Script Engine: The script engine of Party B based on the “lua” data model would make all kinds of tasks and special functions of the server development more
flexible and efficient. 

 For the functional requirements of the software projects under this Contract and the detailed
technology requirements and standards, Party B shall provide the technology materials to Party A due to the confidentiality of such information. 
  

	 	(3)	The Degree of Industrialization Development of the Technology 

  

	 	i.	The Advantages of Company Technology 

 The engine of the
cross-platform network allows Party B to use a single server to deal with thousands of connections, and the script engine of Party B based on the “lua” data model makes all kinds of tasks for developing servers more flexible and efficient.

 All of the above technologies are at its leading level domestically in China. 
  

	 	ii.	Industry Overview of Online Game 

 There are many
differences between the online game industry and other industries. The most prominent point is that the online game industry is an industrial chain composed of research, operation, media and users together. The main line of the online game
industrial chain is online game developers, online game operators, channel vendors, telecom operators and users. Among these lines, the online game operators who will directly face upstream developers and the downstream selling channels and users
are the core of the whole industrial chain. The auxiliary line of online game industrial chain involves IT games, manufacturing, game industry and the 

 English Translation 
  

 
exhibition industry; these rich industrial chains are mutually related to each other. Following the development of the online game standards, the relevant
industries obtained huge commercial opportunities, especially in the telecom and IT game industry. 
 In addition, other than Kingsoft,
Shanda, Netease and Object Software presently in China, there are other producers (or game operator) with great abilities of developing online games, like Suzhou Snail, Fire Fox Digital, Pixel Software; some of which develop and operate the game at
the same time. Independent research and development is the essential way to develop the national game industry. Although domestic games are limited due to the consciousness, culture and experience at present, research and development will be
increasingly emphasized due to the demand for market and industry development.
