A. Effective November 2, 1998, Pioneering Management Corporation ("PMC") will
change its name to Pioneer Investment Management, Inc. Wherever "Pioneering
Management Corporation" or "PMC" appears it is replaced by "Pioneer Investment
Management, Inc." or "Pioneer Investments," respectively.

B. The following is appended to the description of the Fund's Class B Plan:

The Class B Plan and underwriting agreement have been amended effective
September 30, 1998 to permit Pioneer Funds Distributor, Inc. ("PFD") to sell its
right to receive distribution fees under the Plan and CDSC's to third parties.
PFD enters into such transactions to finance the payment of commissions to
brokers at the time of sale and other distribution-related expenses. In
connection with such amendments, the Fund has agreed that the distribution fee
will not be terminated or modified (including a modification by change in the
rules relating to the conversion of Class B shares into Class A shares) with
respect to Class B shares (a) issued prior to the date of any termination or
modification or (b) attributable to Class B shares issued through one or a
series of exchanges of shares of another investment company for which PFD acts
as principal underwriter which were initially issued prior to the date of such
termination or modification or (c) issued as a dividend or distribution upon
Class B shares initially issued or attributable to Class B shares issued prior
to the date of any such termination or modification except:

         (i) to the extent required by a change in the Investment Company Act of
         1940 (the "1940 Act"), the rules or regulations under the 1940 Act, the
         Conduct Rules of the National Association of


<PAGE>


         Securities Dealers, Inc. (the "NASD") or an order of any court or
         governmental agency, in each case enacted, issued or promulgated after
         September 30, 1998;

         (ii) in connection with a Complete Termination (as defined in the
Plan); or

         (iii) on a basis, determined by the Board of Trustees acting in good
         faith, so long as from and after the effective date of such
         modification or termination: neither the Fund, the adviser nor certain
         affiliates pay, directly or indirectly, a fee to any person for the
         provision of personal and account maintenance services (as such terms
         are used in the Conduct Rules of the NASD) to the holders of Class B
         shares of the Fund and the termination or modification of the
         distribution fee applies with equal effect to all Class B shares
         outstanding from time to time.

The Class B Plan also provides that PFD shall be deemed to have performed all
services required to be performed in order to be entitled to receive the
distribution fee, if any, payable with respect to Class B shares sold through
PFD upon the settlement date of the sale of such Class B shares or in the case
of Class B shares issued through one or a series of exchanges of shares of
another investment company for which PFD acts as principal underwriter or issued
as a dividend or distribution upon Class B shares, on the settlement date of the
first sale on a commission basis of a Class B share from which such Class B
share was derived.

In the amendments to the underwriting agreement, the Fund agreed that subsequent
to the issuance of a Class B share, it would not take any action to waive or
change any CDSC (including a change in the rules applicable to conversion of
Class B shares into another class) in respect of such Class B shares, except (i)
as provided in the Fund's Prospectus or Statement of Additional Information in
effect on September 30, 1998, or (ii) as required by a change in the 1940 Act
and the rules and regulations thereunder, the Conduct Rules of the NASD or any
order of any court or governmental agency enacted, issued or promulgated after
September 30, 1998.

C. The following is a list of the holders of 5% or more of any class of a Fund's
