No sale, exchange, or other transfer of assets may be made by an insurer between any of its separate accounts or between any other investment account and one or more of its separate accounts unless, in case of a transfer into a separate account, such transfer is made solely to establish the account or to support the operation of the contracts with respect to the separate account to which the transfer is made, and unless such transfer, whether into or from a separate account, is made:
The director may approve other transfers among such accounts if, in his opinion, such transfers would not be inequitable.
