| If you invest $10,000 (Column I), your sales charge would be 4.00% or $400 (Column II).                                                                                      | ($10,000 x .04 = $400)               |

There is no sales charge on purchases of $1 million or more, but redemptions of shares so purchased are generally subject to a contingent deferred sales charge (“CDSC”). Class A Shares are subject to a fee under the Fund’s Distribution Plan at the rate of 0.15 of 1% of the average annual net assets represented by the Class A Shares. |

There is no CDSC after Class C Shares have been held beyond the applicable period. For purposes of applying the CDSC and determining the time of conversion, the 12-month and six-year holding periods are considered modified by up to one month depending upon when during a month your purchase of such shares is made. Class C Shares are subject to a fee under the Fund’s Distribution Plan at the rate of 0.75 of 1% of the average annual net assets represented by the Class C Shares and a service fee of 0.25 of 1% of such assets. |
