(1) The credit agreement obliges the lender to make available to the borrower a amount of money in the agreed amount. The borrower is obliged to pay the interest owed and, at the due date, to repay the loan made available.
(2) The agreed interest, unless otherwise provided, is to be paid at the end of each year and, if the loan is to be repaid before the end of a year, upon repayment.
(3) If a time is not specified for repayment of the loan, its due date is subject to the lender or the borrower giving notice of termination. The notice period is three months. If interest is not owed, the borrower also is entitled to repay without giving notice of termination.
