All warrants issued hereunder shall bear interest at not exceeding eight percent per annum payable semiannually; provided, that the first interest payment date may be at any time not later than nine months after the date of issue. If the principal of or interest on any warrant at any time issued hereunder shall not be paid when due, the same shall bear interest after maturity until paid at the rate of eight percent per annum until paid; provided, that at any time after such principal or interest shall have become past due, the board of education may give notice of its intention to pay the same in whole or in part with interest at a specified time and place by publication at least once at least 10 days before the date fixed for such payment in a newspaper published or circulated in the county and also in a daily newspaper published in Montgomery or Birmingham. If such notice shall be duly given and if money to make such payment shall be duly provided, interest on such overdue principal or interest (or the part thereof for payment of which money is so provided) shall cease to accrue on the date fixed for such payment.
