However, any proposed movement of an established unit bank shall be subject to each and every restriction applicable to the location of branch banks as provided in this chapter, and, before giving any such consent and approval, the commissioner shall give to each bank in the county ten (10) days’ notice in writing of the application of any bank to move its domicile.
