I. Overview of the Guarantee

(1) Basic Information of the Guarantee

To meet the operating capital funding needs of Huayang Lianzhong Digital Technology Co., Ltd. (hereinafter referred to as the “Company”), the Company has applied to Bank of Beijing Co., Ltd., Changsha Branch for factoring financing loans of RMB 21.1250 million, with a loan term of 1 year. The Company’s controlling shareholder, Xiangjiang Group, provides a joint and several liability guarantee for the above-mentioned loan. Recently, the Company and Xiangjiang Group have signed the relevant counter-guarantee agreement. The Company provides counter-guarantee in the form of an amount-equivalent joint and several liability guarantee, and pays Xiangjiang Group a guarantee fee with a rate of 0.5% per year.

(2) Internal Decision-Making Procedures

The Company has separately considered and approved the “Proposal on Increasing the Counter-Guarantee Amount for the Controlling Shareholder and Related-Party Transaction” at (i) the 9th meeting (extraordinary) of the sixth session of the board of directors held on July 7, 2025, and (ii) the 4th extraordinary general meeting of shareholders in 2025 held on July 23, 2025. In this instance, Xiangjiang Group, the Company’s controlling shareholder, adds to the Company a financing guarantee amount of RMB 1.0 billion (inclusive). The total maximum guarantee limit is adjusted to RMB 2.0 billion (inclusive). In connection with the above-mentioned guarantee amount, the Company provides Xiangjiang Group with an amount-equivalent joint and several liability counter-guarantee. The validity period of the guarantee amount used (i.e., the signing period of the guarantee agreements) is 12 months from the date on which the Company’s 4th extraordinary general meeting of shareholders in 2025 approves the matter. The guarantee amount may be used on a revolving basis within the usage period. Within the guarantee amount approved by the general meeting, the Company will no longer convene another meeting of the board of directors or the general meeting of shareholders to deliberate on any specific guarantee occurrence. As the counter-guarantee matter falls within the guarantee amount approved by the board of directors and the general meeting of shareholders, it is therefore not necessary to convene another meeting of the board of directors or the general meeting of shareholders to deliberate on this counter-guarantee matter.

Party B’s counter-guarantee period is within the guarantee period of Party A, plus 3 years after Party A performs its guarantee obligations.

(3) Party B provides joint and several liability counter-guarantee to Party A and pays the guarantee fee

The guarantee fee is calculated based on the guarantee balance and the actual number of days of the guarantee, i.e., Guarantee fee = Guarantee balance * actual number of days of guarantee / 360 * 0.5% = guarantee fee. The actual number of days of guarantee is counted from the date on which the guaranteed debt funds reach the account of the obligor. The guarantee fee shall be paid on a quarterly basis.

IV. Necessity and Reasonableness of the Guarantee

In this case, Xiangjiang Group, the Company’s controlling shareholder, provides a guarantee for the Company’s financing application to financial institutions, and the Company provides counter-guarantee. This is conducive to further meeting the Company’s needs for operational and development, improving the Company’s financing efficiency, and is consistent with the Company’s overall interests. The guarantee fee rate that the Company pays to Xiangjiang Group is determined with reference to market conditions, in compliance with relevant provisions and the principles of market-based pricing. The related-party transaction is fair and equitable, and there is no circumstance that harms the interests of the Company or its shareholders. It will not have any adverse impact on the Company’s normal operations and business development.
