(2) A provision that the insurer will furnish to the policyholder, for delivery to each employee or member of the insured group, an individual certificate setting forth in summary form a statement of the essential features of the insurance coverage of the employee or member and to whom benefits are payable.

(4) A provision that, with respect to termination of benefits for, or coverage of, any person who is a dependent child of an insured, the child shall continue to be insured up to and including age 25 so long as the coverage of the member continues in effect, the child remains a dependent of the insured parent or guardian, and the child, in each calendar year since reaching any age specified for termination of benefits as a dependent, has been enrolled for five calendar months or more as a full-time student at a postsecondary institution of higher learning or, if not so enrolled, would have been eligible to be so enrolled and was prevented from being so enrolled due to illness or injury. This paragraph shall not apply to group policies under which an employer provides coverage for dependents of its employees and pays the entire cost of the coverage without any charge to the employee or dependents; and

The policy may provide that the policyholder shall be liable to the insurer for the payment of a pro rata premium for the time the policy was in force during such grace period.
