3. Translation of Main Contract Articles (Condensed but Comprehensive)

Article 1 Loan Type

Party B agrees to provide Party A with a working capital loan under the terms of this contract.

Article 2 Loan Amount and Term

The loan principal is RMB 14,000,000.00. The loan term runs from the value date to the maturity date. The actual amount, value date, maturity date, and initial applicable rate for each drawdown shall be as recorded in the Unit Borrowing Voucher/IOU (借据), which forms an integral part of this contract.

Article 3 Purpose and Use of Funds

The loan is for daily business operations and turnover. Party A shall not change the purpose without Party B’s written consent. Party A shall not divert funds to dividends, investments (financial assets, fixed assets, real estate, equity, futures, securities, trusts, funds, guarantees, options, micro-lending, etc.), private lending, illegal fundraising, or any prohibited sector/purpose. Party A bears liability for any losses caused to Party B by misuse.

Article 4 Interest Rate and Interest Settlement

If the drawdown date is within six (6) months from the signing date, the interest rate equals the Pricing Base Rate on the signing date plus 120 basis points. The loan accrues interest from the actual drawdown/value date using Actual/360. If the loan balance changes, interest is calculated in segments by actual days. Interest is settled monthly on the 20th day (first settlement date: 20 June 2025, or 20th of the relevant month/quarter as selected in the contract). Party A irrevocably authorizes Party B to debit the designated account for interest and other amounts due; insufficient funds constitutes overdue payment.

Article 5 Disbursement and Payment of Loan Proceeds

Disbursement is subject to satisfaction of conditions precedent (as stipulated and/or required by Party B). Party A shall submit a drawdown plan; Party B may review and adjust disbursement arrangements and may suspend/terminate disbursement upon occurrence of specified adverse events (e.g., credit deterioration, material adverse change, misuse risk, etc.).

Article 6 Repayment

The loan may be repaid by scheduled repayment and/or maturity (bullet) repayment as selected. Party A shall maintain sufficient funds in the designated account for automatic debit.

Where this loan is secured, Party A’s obligations are additionally supported by guarantee/collateral documents (担保文件).
