(a) A domestic insurer may not make a contract granting a person or permitting a person to enjoy in fact the management of the insurer to the substantial exclusion of its board of directors or to have the controlling or preemptive right to produce substantially all insurance business for the insurer, unless the contract is filed with and approved by the director. The contract shall be considered approved unless disapproved by the director within 20 days after date of filing, subject to a reasonable extension of time that the director may require by notice given within the 20 days. A disapproval shall be delivered to the insurer in writing, stating the grounds for it.
(b) The director shall disapprove a contract upon a finding that it
(1) subjects the insurer to excessive charges;
(2) is to extend for an unreasonable length of time;
(3) does not contain fair and adequate standards of performance; or
(4) contains other inequitable provision or provisions that impair the proper interests of stockholders or members of the insurer.
