Effective immediately, the reinvestment option (to reinvest
distributions on Units by purchasing additional units at a reduced sales
charge) is changed in two ways: (1) Units purchased by automatic
reinvestment of income distributions will be acquired at net asset value --
no sales charge will be deducted. (2) Any principal distributions will be
paid in cash, and may not be reinvested automatically in additional Units.
