Cancellation of contracts and agreements.

    The Administrator may, at any time during the continuance of his appointment with respect to an insurer and after giving an opportunity to the persons concerned to be heard, cancel or vary (either unconditionally or subject to such conditions as he thinks fit to impose) any contract or agreement (other than a policy) between the insurer and any other person which the Administrator is satisfied is prejudicial to the interest of holders of life insurance policies.
