The department shall consider a person, a firm, a corporation, or an organization to be an illegal member if the person, firm, corporation, or organization:
The membership of any illegal member, as determined by the department, shall be terminated and all accounts shall be purged from the active share accounts of the credit union within the period specified in writing by the department. However, a loan agreement between a terminated member and the credit union is unaffected by the termination and, if a loan involving an illegal member is secured by shares, the share account, to the extent encumbered by the loan, remains valid until unencumbered.
