A.

Interest shall accrue from the actual drawdown date of the borrower and shall be calculated based on the actual amount drawn down and the number of days the funds are used.

Interest calculation formula: interest = principal x actual number of days x daily interest rate.

The daily interest rate calculation basis is 360 days per year. Conversion formula: daily interest rate = annual interest rate / 360.

(2) For item B of the foreign currency borrowing floating interest rate under subparagraph (2) of paragraph 1 of this clause:

Interest shall accrue from the actual drawdown date of the borrower and shall be calculated based on the actual amount drawn down and the number of days the funds are used.

□ Simple interest calculation: interest on the portion calculated based on the pricing benchmark and the portion calculated based on the spread shall both be calculated using the simple interest method.

□ Combined simple and compound interest calculation: for the portion calculated based on the pricing benchmark, the interest on such portion for each business day = (principal of the borrowing + total interest on this portion accrued up to the end of the previous day) x the applicable benchmark daily interest rate for that day; on non-business days, interest shall still be calculated using the simple interest method. Interest on the portion calculated based on the spread shall be calculated using the simple interest method.

The daily interest rate calculation basis is 360 days per year. Conversion formula: daily interest rate = annual interest rate / 360.

The business days referred to above shall mean the local business days of the jurisdiction of the administrator of the pricing benchmark for the relevant currency.

3. Interest settlement method

The borrower shall settle interest in accordance with the following method 1:

(2) Monthly interest settlement, with the 20th day of each month as the interest settlement date and the 21st day as the interest payment date.

If the final repayment date of the loan principal does not fall on an interest payment date, then such final repayment date of the loan principal shall be the interest payment date, and the borrower shall pay all accrued interest in full.

For borrowing that is both overdue and misappropriated, default interest shall be charged at the higher of the applicable default interest rates.
