We know that intellectual property is the most essential property of our customers. Respecting confidentiality, protection of intellectual property is the obligation and responsibility of everyone in Bellen, and it is also one of our priorities. We continue to improve the intellectual property protection management system, use advanced technology, and develop a set of strict and effective protection of intellectual property and information security processes to ensure customers' IP and any confidential information is effectively protected.

Upon collaboration, we will sign a confidentiality agreement and master agreement with the customer. Under the confidentiality agreement, both parties shall carry out technical data sharing and technical discussion. The confidentiality obligation starts from customer's inquiry, and runs through the entire project implementation process. Transfer, control, and store of confidential information are controlled by the corresponding system and process. Our IP team organizes training, audits and daily inspections on a regular or irregular basis to ensure that systems and processes are effectively implemented.

We have introduced the most advanced computer and network behavior management software to effectively restrict and monitor all activities online.

• Only dedicated employees can send out emails with technical information to customers.
• Network and information access control policies applied based on roles and actual needs.
• Every computer (with static IP) is monitored, and all network activities including downloads, uploads, and access are recorded.

We continue to invest in system design and independently developed a project management system, through which users share data including confidential information. By leveraging the system, offline communication and information transfer are reduced hence data security confidentiality are enhanced. The system can strictly control the access, record and trace back the history of operations of all users as needed.

We consistently regards environment, health, and safety as fundamental components for healthy business development. It is also our basic social responsibility and the driving force for sustainable growth of the company. Our EHS policy clearly outlines the organization's aspirations and provides relevant guidance for our employees. We continually invest in human resources, technology, and capital to establish a comprehensive EHS management system that aligns with international standards and is applicable to our current status.

Regarding production safety, we established a rigorous safety evaluation process based on RC1, ARC, RADEX, DSC, SEDEX, and other professional safety testing and evaluation equipment. Moreover, we've implemented a complete safety production responsibility system for all employees, conducting annual safety education and training, along with regular and special inspections for safety checks and hidden danger identification and rectification. Regarding environmental protection, we actively develop green chemistry and clean production technologies, integrating these technologies and concepts into various stages such as new product development, process optimization, and technological improvements.
