(b) Issue a certificate under any lawfully transacted group life or group disability policy, when the master policy is entered into in a state in which the insurer is authorized to do business;
(c) Make a contract pursuant to a pension or retirement plan of an employer when such contract is applied for in a state where the employer is personally present or doing business and the insurer is authorized to do business; and
