Class C shares shall not be subject to a front-end sales charge, but shall be subject to a CDSC and shall be charged an annual distribution fee under a Distribution Plan adopted pursuant to Rule 12b-1 under the 1940 Act.  The amount of and provisions relating to the CDSC, and the amount of the fees under the Distribution Plan pertaining to the Class C shares, are set forth on Schedule B attached hereto.

Class Z shares shall be offered at net asset value only to shareholders of the Fund who have held Fund shares since August 30, 1999 and who purchase such shares directly through the Fund's Distributor for Fund accounts maintained with the Distributor.

5.Conversion Features:  No Class shall be subject to any automatic conversion feature.  Shares of one Class of the Fund may be converted into shares of another Class of the Fund, provided the shareholder requesting the conversion meets the eligibility requirements for the purchase of the new Class of shares of the Fund.  Shares subject to a CDSC or a redemption fee at the time of the requested conversion shall not be eligible for conversion.

• Full-time or part-time employees, and their family members, of The Dreyfus Corporation or any of its affiliates.

• Board members of The Dreyfus Corporation and Board members of the Dreyfus Family of Funds.

• Investors who purchase Class A shares directly through the Fund's Distributor for Fund accounts maintained with the Distributor, and either (i) have, or whose spouse or minor children have, beneficially owned shares and continuously maintained an open account with the Distributor in a Dreyfus-managed fund since on or before February 28, 2006, or (ii) such purchase is for a self-directed investment account that may or may not be subject to a transaction fee.

SCHEDULE B

Contingent Deferred Sales Charge—Class C Shares—A CDSC of 1.00% payable to the Fund's Distributor shall be imposed on any redemption of Class C shares within one year of the date of purchase.  No CDSC shall be imposed to the extent that the net asset value of the Class C shares redeemed does not exceed (i) the current net asset value of Class C shares of the Fund acquired through reinvestment of Fund dividends or capital gain distributions, plus (ii) increases in the net asset value of the shareholder's Class C shares above the dollar amount of all payments for the purchase of Class C shares of the Fund held by such shareholder at the time of redemption.

If the aggregate value of the Class C shares redeemed has declined below their original cost as a result of the Fund's performance, a CDSC may be applied to the then-current net asset value rather than the purchase price.

In determining whether a CDSC is applicable to a redemption, the calculation shall be made in a manner that results in the lowest possible rate.  Therefore, it shall be assumed that the redemption is made first of amounts representing Class C shares of the Fund acquired pursuant to the reinvestment of Fund dividends and distributions; then of amounts representing the increase in net asset value of Class C shares above the total amount of payments for the purchase of Class C shares made during the preceding year; and finally, of amounts representing the cost of Class C shares held for the longest period of time.

Waiver of CDSC—The CDSC shall be waived in connection with (a) redemptions made within one year after the death or disability, as defined in Section 72(m)(7) of the Code, of the shareholder, (b) redemptions by Retirement Plans, provided that the shares being redeemed were purchased through a financial intermediary that performs recordkeeping or other administrative services for the Retirement Plan and has entered into an agreement with the Fund's Distributor relating to such services, or were purchased directly through the Fund's Distributor, (c) redemptions as a result of a combination of any investment company with the Fund by merger, acquisition of assets or otherwise, (d) redemptions due to receiving applicable required minimum distributions from IRA accounts (other than Roth IRAs or Coverdell Education Savings Accounts) upon attaining age 70-1/2, and (e) redemptions pursuant to any systematic withdrawal plan as described in the Fund's prospectus.  The CDSC also shall be waived in connection with redemptions by Retirement Plans of Fund shares purchased on or before January 31, 2016.  If a CDSC waiver is discontinued, Fund shares subject to a CDSC which were purchased prior to the termination of such waiver shall have the CDSC waived as provided in the Fund's prospectus at the time of the purchase of such shares.

Amount of Distribution Plan Fees—Class C Shares—.75 of 1% of the value of the average daily net assets of Class C.
