(1) Premiums, dues or fees shall not be excessive or inadequate, as herein defined, nor shall they be unfairly discriminatory;

(3) No premiums, dues or fees shall be held to be inadequate unless such premiums, dues or fees are unreasonably low for the coverage provided and the continued use of such premiums, dues or fees endangers the solvency of the corporation using the same;

(5) If the director, after such hearings, for good cause finds that such premiums, dues or fees do not meet the provisions of this section, he shall issue an order specifying in what respects any such premiums, dues or fees fails to meet the provisions of this section and stating when, within a reasonable period of time thereafter, the further use of such premiums, dues or fees by the corporation which is the subject of the examination shall be prohibited and a copy of such order shall be sent to such corporation.
