(3). Penalty Rate and Compound Rate

If the loan is not used for the specified purpose, Party A shall charge the penalty interest on the past-due portion starting on the date the loan was misused until the principal and interest are repaid. The daily rate of penalty interest on misused loan is 0.05%.

2. Interest Settlement Method

2.1 The interest is settled monthly, with the 20th of each month is the settlement date and the 21st of each month is the interest payment date.

2.2 If the last repayment installment for the loan principal is not on the interest payment date, then the last repayment date of the loan principal shall be the interest payment date and Party B must pay off all interest on that date. When the loan matures, the interest must be paid off with the principal. If the loan maturity date is a statutory holiday or a public weekend day, and the loan must be repaid on the last business day before such statutory holiday or a public weekend day, the interest shall be charged according to the provisions herein, but the interest for the days between the maturity date and the repayment date based on the interest calculation method must be deducted; if the loan is repaid on the first business day after such statutory holiday or a public weekend day, the interest for the days between the maturity date and the repayment date based on the interest calculation method must be added.
