(4) The fact that two or more insurers, whether or not members or subscribers of an advisory organization, consistently or intermittently use the same rates, rating systems, forms, prospective loss costs, underwriting rules or practices, surveys, inspections, or similar materials shall not be sufficient basis to establish a violation of this section.

(5) No insurer, advisory organization, or statistical agent shall make any arrangement with any other insurer, advisory organization, statistical agent, or other person which has the purpose or effect of unreasonably restraining trade or of substantially lessening competition in the business of insurance.
