If an individual insured under a group life-insurance policy hereafter delivered in this state becomes entitled under the terms of the policy to have an individual policy of life insurance issued without evidence of insurability, subject to making of application and payment of the first premium within the period specified in the policy, and if the individual is not given notice of the existence of the right at least fifteen (15) days prior to the expiration date of the period, then in that event, the individual shall have an additional period within which to exercise the right, but nothing herein contained shall be construed to continue any insurance beyond the period provided in the policy. This additional period shall expire fifteen (15) days next after the individual is given notice, but in no event shall the additional period extend beyond sixty (60) days after the expiration date of the period provided in the policy. The notice shall clearly set forth the required conversion process. The notice may include the conversion provisions of the policy and certificate, but the notice may not just make reference to these provisions. The notice does not require prior approval, but the insurer is responsible to assure that the notice is clear and provides all the necessary information. If the insurer allows the conversion notice to be delivered by the employer, the insurer shall ensure that no other employer notice is included with the conversion notice. Written notice presented to the individual or mailed by the policy holder to the last-known address of the individual or mailed by the insurer to the last-known address of the individual as furnished by the policyholder shall constitute notice for the purpose of this paragraph.
