(a) agreements may be made among insurers with respect to the equitable apportionment among them of insurance which may be afforded applicants who are in good faith entitled to but who are unable to procure insurance through ordinary methods, and the insurers may agree among themselves on the use of reasonable rate modifications for the insurance.

(b) Agreements and rate modifications made under subsection (a) shall be subject to the filing, review and prior approval of the commissioner. Filings shall be available for use at the expiration of a sixty-day (60) period if not earlier approved or disapproved by the commissioner. The commissioner may by written order to the insurer within the sixty-day (60) period extend the period for approval or disapproval for an additional thirty (30) days. This section shall apply to filings for the Fair Plan and the Joint Underwriting Association.
