(1) A state trust institution may act as a fiduciary or otherwise engage in a trust business in this or any other state or foreign country, subject to complying with applicable laws of the state or foreign country, at an office established and maintained pursuant to this chapter, at a branch or at any other authorized location other than an office or branch.
(2) In addition, a state trust institution may conduct any activities at any office outside this state that are permissible for a trust institution chartered by the host state where the office is located, except to the extent such activities are expressly prohibited by the laws of this state or by any rule or order of the Bank Commissioner applicable to the state trust institution. Provided, however, that the commissioner may waive any such prohibition if he or she determines, by order or rule, that the involvement of out-of-state offices of state trust institutions in particular activities would not threaten the safety or soundness of the state trust institutions.
