(a) if a petition for the appointment of an examiner is presented in relation to the institution under the Companies (Amendment) Act, 1990;
(b) if a petition is presented, or an effective resolution is passed, for the appointment of a liquidator in relation to the institution;
(c) if a receiver over any assets of the institution is appointed;
