In group life policies there shall be a provision that if the insurance, or any portion of it, on a person covered under the policy ceases because of termination of employment or of membership in the class or classes eligible for coverage under the policy, such person shall be entitled to have issued to him by the insurer, without evidence of insurability, an individual policy of life insurance without disability or other supplementary benefits, provided that application for the individual policy has been made, and the first premium paid to the insurer, within thirty-one days after the termination, and provided further that:

1. The individual policy, at the option of such person, is on any one of the forms, except term insurance, then customarily issued by the insurer at the age and for the amount applied for.

2. The individual policy is in an amount not in excess of the amount of life insurance which ceases because of the termination, less, in the case of a person whose membership in the class or classes eligible for coverage terminates but who continues in employment in another class, the amount of any life insurance for which the person is or becomes eligible under any other group policy within thirty-one days after the termination, provided that any amount of insurance which has matured on or before the date of the termination as an endowment payable to the person insured, whether in one sum or in installments or in the form of an annuity, shall not, for the purposes of this provision, be included in the amount which is considered to cease because of the termination.

3. The premium on the individual policy is at the insurer’s then customary rate applicable to the form and amount of the individual policy, to the class of risk to which the person then belongs, and to his age attained on the effective date of the individual policy.
