A policy which contains any exclusion or restriction pursuant to § 58-15-45 shall also provide that in the event of death under the circumstances to which any such exclusion or restriction is applicable, the insurer will return all premiums received under the policy with adjustment for indebtedness and dividend credits. If the policy is a variable policy, the insurer may, if the policy so provides, return all premiums received under the policy with adjustment for indebtedness and adjustment to reflect the investment experience of the separate account.
