      The undersigned, being at least a majority of the duly elected and
qualified Trustees of AB Municipal Income Fund II, a business trust organized

      Section 6.2. Establishment and Designation of Certain Portfolios; General
      Provisions for All Portfolios. Without limiting the authority of the
      Trustees set forth in Section 6.1(a) hereof to establish and designate

      Arizona Portfolio, the AB Massachusetts Portfolio, the AB Michigan
      Portfolio, the AB Minnesota Portfolio, the AB New Jersey Portfolio, the AB
      Ohio Portfolio, the AB Pennsylvania Portfolio, and the AB Virginia

      Portfolio.

      This instrument shall become effective upon its execution. This instrument
