If any facts occur which would entitle the commissioner under Section 17621 to take possession of the property, business and assets of a licensee the commissioner may appoint a conservator of a licensee and require of him such bond as the commissioner deems proper. The commissioner may also, upon the request of the board of directors of a licensee, appoint a conservator of such licensee and require of him such bond as the commissioner deems proper. The conservator, under the direction of the commissioner, shall take possession of the property, business and assets of the licensee and take such action as he may deem necessary to conserve the assets of such licensee pending

further disposition of its business. The conservator shall retain such possession until the property, business and assets of the licensee are returned to the licensee or until further order of the commissioner.
