Members who are appointed by the board shall serve for a term not to exceed six (6) years. Such appointed board members shall serve at the pleasure of the board and may be removed with or without cause by a majority vote of the elected members of the board. Appointed board members shall have the same duties, oaths and obligations as elected board members; provided however, that an appointed board member shall not be entitled to vote on any decision to levy a tax pursuant to this chapter.
