III. Main Contents of the Guarantee Agreements

The Company proposes to provide new financing and performance guarantees to its controlled subsidiaries (including newly established ones), including Guangdong Jihong and Xiamen Giikin, with an estimated guarantee amount not exceeding RMB2.5 billion, and the relevant agreements are yet to be signed. The Company will determine the financial institutions and day-to-day business counterparties based on the actual needs. The financing and performance guarantee amount, type, guarantee method, and guarantee term shall be subject to the finalized contracts signed.

IV. Opinions of the Board

The new guarantees refer to such guarantees provided between the Company and its controlled subsidiaries within the scope of consolidated statements for financing and performance, which is conducive to the Company improving capital turnover efficiency, meeting the needs of day-to-day production and operation and market expansion, and is in line with the Company's development strategy and overall interests.

The Company can exercise effective control over the operational management, financial and capital control, and investment and financing of the controlled subsidiaries within the scope of consolidated statements, and therefore the guarantee risks are controllable. Where there are other minority shareholders in the controlled subsidiaries, they are required in principle to provide equivalent guarantees in proportion to their capital contributions. This guarantee will not adversely affect the Company and does not prejudice the interests of the Company and its Shareholders.
