I. EXPENSE INFORMATION 

   
   This table is designed to help you understand the charges and expenses 
that you, as a shareholder, will bear directly or indirectly when you invest 
in the Fund. The table reflects annual operating expenses based on actual 
expenses for the fiscal year ended December 31, 1995. For Class C shares, 
operating expenses are based on estimated expenses that would have been 
incurred if Class C shares had been outstanding for the entire fiscal year 
ended December 31, 1995.

+   Class C shares were first offered on January 31, 1996. 

(1) Purchases of $1 million or more and purchases by participants in certain 
    group plans are not subject to an initial sales charge but may be subject 
    to a contingent deferred sales charge ("CDSC") as further described under 
    "How to Sell Fund Shares." 

(2) Separate fees (currently $10 and $20, respectively) apply to domestic and 
    international wire transfers of redemption proceeds. 
    

    Example: 

   
   You would pay the following expenses on a $1,000 investment in the Fund, 
assuming a 5% annual return with or without redemption at the end of each 
time period: 
    

                            1 Year   3 Years    5 Years    10 Years 
Class A Shares               $69       $94        $120       $196 
Class B Shares 
- --Assuming complete 
  redemption at end of 
  period                     $59       $88        $120       $199* 
- --Assuming no redemption     $19       $58        $100       $199* 
Class C Shares** 
- --Assuming complete 
  redemption at end of 
  period                     $29       $58        $100       $216 
- --Assuming no redemption     $19       $58        $100       $216 

 *Class B shares convert to Class A shares eight years after purchase; 
  therefore, Class A expenses are used after year eight. 
**Class C shares redeemed during the first year after purchase are subject to 
  a 1% CDSC. 

   The example above assumes reinvestment of all dividends and distributions 
and that the percentage amounts listed under "Annual Operating Expenses" 
remain the same each year. 

   
   The example is designed for information purposes only, and should not be 
considered a representation of past or future expenses or return. Actual Fund 
expenses and return will vary from year to year and may be higher or lower 
than those shown. 
    

   
   For further information regarding management fees, 12b-1 fees and other 
expenses of the Fund, see "Management of the Fund," "Distribution Plans" and 
"How To Buy Fund Shares" in this Prospectus and "Management of the Fund" and 
"Underwriting Agreement and Distribution Plans" in the Statement of 
Additional Information. The Fund's payment of a Rule 12b-1 fee may result in 
long-term shareholders indirectly paying more than the economic equivalent of 
the maximum sales charge permitted under the Conduct Rules of the National 
Association of Securities Dealers, Inc. ("NASD"). 
    

   The maximum initial sales charge is reduced on purchases of specified 
larger amounts of Class A shares and the value of shares owned in other 
Pioneer mutual funds is taken into account in determining the applicable 
initial sales charge. See "How to Buy Fund Shares." No sales charge is 
applied to exchanges of shares of the Fund for shares of other publicly 
available Pioneer mutual funds. See "How to Exchange Fund Shares."

III. INVESTMENT OBJECTIVE, POLICIES AND RISKS 

   The investment objective of the Fund is to obtain appreciation of capital. 
The Fund invests in common stocks, together with preferred stocks, bonds and 
debentures which are convertible into common stocks. Current income will be 
incidental to the Fund's primary objective. In selecting securities for 
investment, the investment adviser attempts to identify companies that have 
better-than-average earnings growth potential and those industries that stand 
to enjoy the greatest benefit from the predicted economic environment. The 
Fund seeks to purchase the securities of companies that are thought to be 
best situated in those industry groupings. The Fund invests in companies in a 
variety of industries in an attempt to reduce its overall exposure to 
investment and market risks. 

   In pursuing its objective, the Fund purchases portfolio securities with 
the view of retaining them on a long-term basis. However, securities in the 
Fund's portfolio will be sold whenever PMC, the Fund's investment adviser, 
believes that it is necessary without regard to the length of time the 
particular security may have been held. This policy is subject to certain 
requirements for continuing the Fund's qualification as a regulated 
investment company under the Internal Revenue Code of 1986, as amended (the 
"Code"). A high portfolio turnover rate (100% or more) involves greater 
expenses to the Fund and may increase the possibility of shareholders 
realizing taxable income and/or capital gains. See "Financial Highlights" for 
actual turnover rates. 

   
   Part or all of the Fund's assets may be temporarily invested in securities 
of the United States ("U.S.") government, its agencies or instrumentalities, 
commercial paper, bank certificates of deposit and time deposits, bankers' 
acceptances, other fixed income securities and repurchase agreements with 
banks and broker-dealers with respect to any of the foregoing instruments. At 
times, PMC believes that such investments are desirable due to present or 
anticipated market or economic conditions which are affecting or could affect 
the values of the Fund's investments, as well as for liquidity purposes or as 
a temporary investment pending investment in equity and equity-related 
securities. The Fund may invest in lower rated or unrated securities. These 
securities involve greater risks of default and price fluctuations due to 
credit, economic, liquidity and market concerns. 
    

Restricted and Illiquid Securities 

   The Fund may invest in restricted securities (i.e., securities that would 
be required to be registered prior to distribution to the public), including 
securities eligible for resale to "qualified institutional buyers" in 
accordance with Rule 144A under the Securities Act of 1933 ("1933 Act"). In 
addition, the Fund will not invest more than 15% of its net assets in 
illiquid securities, which includes repurchase agreements maturing in more 
than seven days, securities that are not readily marketable and restricted 
securities sold and offered under Rule 144A that are illiquid either as a 
result of legal or contractual restrictions or the absence of a trading 
market. 

   The Board of Trustees of the Fund may adopt guidelines and delegate to PMC 
the daily function of determining and monitoring the liquidity of restricted 
securities. The Board of Trustees, however, will retain sufficient oversight 
and be ultimately responsible for the determinations. Since it is not 
possible to predict with assurance exactly how the market for restricted 
securities eligible for resale pursuant to Rule 144A will continue to 
develop, the Board of Trustees will carefully monitor the Fund's investments 
in these securities, focusing on such important factors, among others, as 
valuation, liquidity and availability of information. This investment 
practice could have the effect of increasing the level of illiquidity in the 
Fund to the extent that qualified institutional buyers become for a time 
uninterested in purchasing these restricted securities. 

   The purchase price and subsequent valuation of restricted securities 
normally reflect a discount from the price at which such securities trade 
when they are not restricted to the extent that the restriction makes them 
less liquid. The amount of the discount from the prevailing market price is 
expected to vary depending upon the type of security, the character of the 
issuer, the party who will bear the expenses of registering the restricted 
securities and prevailing supply and demand conditions. 

Foreign Securities 

   The Fund may invest up to 30% of its assets at the time of investment in 
listed and unlisted foreign securities. While such investments are intended 
to reduce risk by permitting greater diversification of the Fund's portfolio, 
investments in securities of foreign issuers entail certain risks not 
associated with investments in domestic issuers. Such risks include 
fluctuations in foreign currency exchange rates; possible expropriation or 
nationalization of foreign companies; imposition of exchange control 
regulations; currency blockage or dividends or interest withheld at the 
source; unfavorable price spreads on currency exchanges; higher transaction 
costs; less public information about issuers of securities; lack of uniform 
auditing, accounting and financial reporting standards; less governmental 
regulation of foreign stock exchanges and brokers; less liquidity and greater 
volatility of securities of foreign companies; or imposition of foreign 
taxes. Therefore, the Fund intends to invest primarily in the companies 
organized under the laws of those nations which are considered to have 
relatively stable and friendly governments, e.g., major industrialized 
nations such as the United Kingdom, France, Canada, Germany and Japan. 

Lending of Portfolio Securities 

   The Fund may seek to increase its income by lending portfolio securities, 
provided that the value of the securities loaned would not exceed one-third 
of the value of the total assets of the Fund. Under present regulatory 
policies, such loans may be made to institutions, such as certain broker- 
dealers, and are required to be secured continuously by collateral in cash, 
cash equivalents, or U.S. government securities maintained on a current basis 
in an amount at least equal to the market value of the securities loaned. The 
Fund may experience loss or delay in the recovery of its securities if the 
institution with which it has engaged in a portfolio loan transaction 
breaches its agreement with the Fund. 

                                       5
<PAGE> 

When Issued Securities 

   The Fund may also purchase and sell securities on a "when issued" and 
"delayed delivery" basis. These transactions are subject to market 
fluctuation; the value at the time of delivery may be more or less than the 
purchase price. Since the Fund will rely on the buyer or seller, as the case 
may be, to consummate the transaction, failure by the other party to complete 
the transaction may result in the Fund missing the opportunity of obtaining a 
price or yield considered to be advantageous. No interest accrues to the Fund 
prior to delivery. When the Fund is the buyer in such a transaction it will 
maintain, in a segregated account with its custodian, cash, U.S. government 
securities, or high-grade, liquid debt obligations having an aggregate value 
equal to the amount of such purchase commitments until payment is made. The 
Fund will make commitments to purchase securities on such basis only with the 
intention of actually acquiring these securities, but the Fund may sell such 
securities prior to the settlement date if such sales are considered to be 
advisable. To the extent the Fund engages in "when issued" and "delayed 
delivery" transactions, it will do so for the purpose of acquiring securities 
for the Fund's portfolio consistent with the Fund's investment objective and 
policies and not for the purpose of investment leverage. 

Repurchase Agreements 

   A repurchase agreement is an instrument under which the purchaser acquires 
ownership of the obligation but the seller agrees, at the time of sale, to 
repurchase the obligation at a mutually agreed upon time and price. The 
resale price is in excess of the purchase price and reflects an agreed upon 
market rate unrelated to the coupon rate on the purchased security. Such 
transactions afford an opportunity for the Fund to invest temporarily 
available cash. In the event of the insolvency of the seller, or an order to 
stay execution of an agreement by a court or regulatory authority, the Fund 
could incur costs before being able to sell the underlying obligations and 
the Fund's realization of the underlying obligations could be delayed or 
limited, which could adversely affect the price the Fund receives for such 
obligations. There is also a risk that the seller may fail to repurchase the 
underlying obligations in which case the Fund may incur possible disposition 
costs and a loss if the proceeds of the sale of such obligations to a third 
party are less than the repurchase price. To guard against these 
possibilities, PMC, under guidelines established by the Fund's Board of 
Trustees, will evaluate the creditworthiness of the seller. The Fund will 
enter into repurchase agreements only with those institutions that the 
investment adviser believes present minimal credit risks and which furnish 
collateral at least equal in value or market price to the amount of the 
repurchase obligations. Repurchase agreements maturing in more than seven 
days are considered by the Fund to be illiquid. 

Risk Factors 

   Because prices of securities fluctuate from day to day, the value of an 
investment in the Fund will vary based upon the Fund's investment 
performance. The value of your shares in the Fund may, at any time, be higher 
or lower than your original cost. The Fund may invest in debt securities with 
varying maturities. In general, the longer the maturity of a security, the 
higher the yield and the greater the potential for price fluctuations. A 
decline in interest rates generally produces an increase in the value of debt 
securities in the Fund's portfolio, while an increase in interest rates 
usually reduces the value of these securities. 

Additional Restrictions 

   In addition to the investment objective and policies discussed above, the 
Fund's investments are subject to other restrictions which are described in 
its Statement of Additional Information. Unless otherwise stated, the Fund's 
investment objective and restrictions are considered fundamental and cannot 
be changed without shareholder approval. Unless expressly designated as a 
fundamental policy, the Fund's investment policies may be changed without 
shareholder approval by the Board of Trustees of the Fund. 

IV. MANAGEMENT OF THE FUND 

   
   The Board of Trustees of the Fund has overall responsibility for 
management and supervision of the Fund. There are currently eight Trustees, 
six of whom are not "interested persons" of the Fund as defined in the 
Investment Company Act of 1940 (the "1940 Act"). The Board meets at least 
quarterly. By virtue of the functions performed by Pioneering Management 
Corporation ("PMC") as the Fund's investment adviser, the Fund requires no 
employees other than its executive officers, all of whom receive their 
compensation from PMC or other sources. The Statement of Additional 
Information contains the names and general business and professional 
background information of each Trustee and executive officer of the Fund. 
    

   Each domestic equity portfolio managed by PMC, including the Fund, is 
overseen by the Domestic Equity Portfolio Management Committee, which 
consists of PMC's most senior domestic equity professionals. The committee is 
chaired by Mr. David Tripple, PMC's President and Chief Investment Officer 
and Executive Vice President of each of the Pioneer mutual funds. Mr. Tripple 
joined PMC in 1974 and has had general responsibility for PMC's investment 
operations and specific portfolio assignments for over five years. Mr. 
Jeffrey B. Poppenhagen, Portfolio Manager, assumed primary responsibility for 
the day-to-day management of the Fund on February 20, 1996. Mr. Poppenhagen 
joined PMC in February, 1996. Prior to joining PMC, Mr. Poppenhagen was a 
portfolio manager and analyst for a number of equity portfolios. 

   
   The Fund is managed under a contract with PMC. PMC serves as investment 
adviser to the Fund and is responsible for the overall management of the 
Fund's business affairs, subject only to the authority of the Fund's Board of 
Trustees. PMC is a wholly owned subsidiary of The Pioneer Group, Inc. 
("PGI"), a publicly traded Delaware corporation. Pioneer Funds Distributor, 
Inc. ("PFD"), an indirect wholly-owned subsidiary of PGI, is the principal 
underwriter of the Fund. Prior to December 1, 1993, FMC acted as investment 
adviser and principal underwriter to the Fund. 
    

   In addition to the Fund, PMC also manages and serves as the investment 
adviser for other mutual funds and is an investment adviser to certain other 
institutional accounts. 

                                       6
<PAGE> 

   
PMC's and PFD's executive offices are located at 60 State Street, Boston, 
Massachusetts 02109. In an effort to avoid conflicts of interest with the 
Fund, the Fund and PMC have adopted a Code of Ethics that is designed to 
maintain a high standard of personal conduct by directing that all personnel 
defer to the interests of the Fund and its shareholders in making personal 
securities transactions. 
    

   Under the terms of its contract with the Fund, PMC provides the Fund with 
an investment program consistent with its investment objective and policies. 
PMC furnishes the Fund with office space, equipment and personnel for 
managing the affairs of the Fund. PMC also pays all expenses in connection 
with the management of the affairs of the Fund except (i) charges and 
expenses for fund accounting, pricing and appraisal services and related 
overhead, including, to the extent such services are performed by personnel 
of PMC or its affiliates, office space and facilities and personnel 
compensation, training and benefits; (ii) the charges and expenses of 
auditors; (iii) the charges and expenses of any custodian, transfer agent, 
plan agent, dividend disbursing agent and registrar appointed by the Fund; 
(iv) issue and transfer taxes chargeable to the Fund in connection with 
securities transactions to which the Fund is a party; (v) insurance premiums, 
interest charges, dues and fees for membership in trade associations and all 
taxes and corporate fees payable by the Fund to federal, state or other 
governmental agencies; (vi) fees and expenses involved in registering and 
maintaining registrations of the Fund and/or its shares with the SEC, state 
or blue sky securities agencies and foreign countries, including the 
preparation of Prospectuses and Statements of Additional Information for 
filing with regulatory agencies; (vii) all expenses of shareholders' and 
Trustees' meetings and of preparing, printing and distributing prospectuses, 
notices, proxy statements and all reports to shareholders and to governmental 
agencies; (viii) charges and expenses of legal counsel to the Fund and the 
Trustees; (ix) distribution fees paid by the Fund in accordance with Rule 
12b-1 promulgated by the SEC pursuant to the 1940 Act; (x) compensation of 
those Trustees of the Fund who are not affiliated with or interested persons 
of PMC, the Fund (other than as Trustees), PGI or PFD; (xi) the cost of 
preparing and printing share certificates; and (xii) interest on borrowed 
money, if any. In addition to the expenses described above, the Fund shall 
pay all brokers' and underwriting commissions chargeable to the Fund in 
connection with securities transactions to which the Fund is a party. 

   Orders for the Fund's portfolio securities transactions are placed by PMC, 
which strives to obtain the best price and execution for each transaction. In 
circumstances where two or more broker-dealers are in a position to offer 
comparable prices and execution, consideration may be given to whether the 
broker-dealer provides investment research or brokerage services or sells 
shares of the Fund or other Pioneer mutual funds. See the Statement of 
Additional Information for a further description of PMC's brokerage 
allocation practices. 

   As compensation for its management services for the Fund and certain 
expenses which PMC incurs, PMC is entitled to a management fee from the Fund 
at the annual rates set forth below as a percentage of average daily net 
assets: 

                         Net Assets                              Annual Fee 
- ------------------------------------------------------------   -------------- 
For assets up to $250,000,000                                       .50% 
For assets in excess of $250,000,000 to $300,000,000                .48% 
Over $300,000,000                                                   .45% 

   For the fiscal year ended December 31, 1995, the Fund paid a management 
fee to PMC of $876,379. 

   
   John F. Cogan, Jr., Chairman and President of the Fund, Chairman of PFD, 
President and a Director of PGI and Chairman and a Director of PMC, owned 
approximately 14% of the outstanding capital stock of PGI as of the date of 
this Prospectus. 
    

V. FUND SHARE ALTERNATIVES 

   The Fund continuously offers three Classes of shares designated as Class 
A, Class B and Class C shares, as described more fully in "How to Buy Fund 
Shares." If you do not specify in your instructions to the Fund which Class 
of shares you wish to purchase, exchange or redeem, the Fund will assume that 
your instructions apply to Class A shares. 

   Class A Shares. If you invest less than $1 million in Class A shares, you 
will pay an initial sales charge. Certain purchases may qualify for reduced 
initial sales charges. If you invest $1 million or more in Class A shares, no 
sales charge will be imposed at the time of purchase, however, shares 
redeemed within 12 months of purchase may be subject to a CDSC. Class A 
shares are subject to distribution and service fees at a combined annual rate 
of up to 0.25% of the Fund's average daily net assets attributable to Class A 
shares. 

   Class B Shares. If you plan to invest up to $250,000, Class B shares are 
available to you. Class B shares are sold without an initial sales charge, 
but are subject to a CDSC of up to 4% if redeemed within six years. Class B 
shares are subject to distribution and service fees at a combined annual rate 
of 1.00% of the Fund's average daily net assets attributable to Class B 
shares. Your entire investment in Class B shares is available to work for you 
from the time you make your investment, but the higher distribution fee paid 
by Class B shares will cause your Class B shares (until conversion) to have a 
higher expense ratio and to pay lower dividends, to the extent dividends are 
paid, than Class A shares. Class B shares will automatically convert to Class 
A shares, based on relative net asset value, eight years after the initial 
purchase. 

   
   Class C Shares. Class C shares are sold without an initial sales charge, 
but are subject to a 1% CDSC if they are redeemed within the first year after 
purchase. Class C shares are subject to distribution and service fees at a 
combined annual rate of up to 1% of the Fund's average daily net assets 
attributable to Class C shares. Your entire investment in Class C shares is 
available to work for you from the time you make your investment, but the 
higher distribution fee paid by Class C shares will cause your Class C shares 
to have a higher expense ratio and to pay lower dividends, to the extent 
dividends are paid, than Class A shares. Class C shares have no conversion 
feature. 
    

   
   Selecting a Class of Shares. The decision as to which Class to purchase 
depends on the amount you invest, the intended length of the investment and 
your personal situation. If you are making an investment that qualifies for 
reduced sales charges, 
    

                                       7
<PAGE> 

you might consider Class A shares. If you prefer not to pay an initial sales 
charge on an investment of $250,000 or less and you plan to hold the 
investment for at least six years, you might consider Class B shares. If you 
prefer not to pay an initial sales charge and you plan to hold your 
investment for one to eight years, you may prefer Class C shares. 

   Investment dealers or their representatives may receive different 
compensation depending on which Class of shares they sell. Shares may be 
exchanged only for shares of the same Class of another Pioneer mutual fund 
and shares acquired in the exchange will continue to be subject to any CDSC 
applicable to the shares of the Fund originally purchased. Shares sold 
outside the U.S. to persons who are not U.S. citizens may be subject to 
different sales charges, CDSCs and dealer compensation arrangements in 
accordance with local laws and business practices. 

VI. SHARE PRICE 

   Shares of the Fund are sold at the public offering price, which is the net 
asset value per share, plus the applicable sales charge. Net asset value per 
share of a Class of the Fund is determined by dividing the value of its 
assets, less liabilities attributable to that Class, by the number of shares 
of that Class outstanding. The net asset value is computed once daily, on 
each day the New York Stock Exchange (the "Exchange") is open, as of the 
close of regular trading on the Exchange. 

   Securities are valued at the last sale price on the principal exchange or 
market where they are traded. Securities which have not traded on the date of 
valuation or securities for which sales prices are not generally reported are 
valued at the mean between the current bid and asked prices. Securities 
quoted in foreign currencies are converted to U.S. dollars utilizing foreign 
exchange rates employed by the Fund's independent pricing services. 
Generally, trading in foreign securities is substantially completed each day 
at various times prior to the close of the Exchange. The values of such 
securities used in computing the net asset value of the Fund's shares are 
determined as of such times. Foreign currency exchange rates are also 
generally determined prior to the close of the Exchange. Occasionally, events 
which affect the values of such securities and such exchange rates may occur 
between the times at which they are determined and the close of the Exchange 
and will therefore not be reflected in the computation of the Fund's net 
asset value. If events materially affecting the value of such securities 
occur during such period, then these securities are valued at their fair 
value as determined in good faith by the Trustees. All assets of the Fund for 
which there is no other readily available valuation method are valued at 
their fair value as determined in good faith by the Trustees. 

VII. HOW TO BUY FUND SHARES 

   You may buy Fund shares from any securities broker-dealer which has a 
sales agreement with PFD. If you do not have a securities broker-dealer, 
please call 1-800-225-6292. Shares will be purchased at the public offering 
price, that is, the net asset value per share plus any applicable sales 
charge, next computed after receipt of a purchase order, except as set forth 
below. 

   
   The minimum initial investment is $1,000 for Class A, Class B and Class C 
shares except as specified below. The minimum initial investment is $50 for 
Class A accounts being established to utilize monthly bank drafts, government 
allotments, payroll deduction and other similar automatic investment plans. 
Separate minimum investment requirements apply to retirement plans and to 
telephone and wire orders placed by broker-dealers; no sales charges or 
minimum requirements apply to the reinvestment of dividends or capital gains 
distributions. The minimum subsequent investment is $50 for Class A shares 
and $500 for Class B and Class C shares except that the subsequent minimum 
investment amount for Class B and Class C share accounts may be as little as 
$50 if an automatic investment plan is established (see "Automatic Investment 
Plans"). 
    

   
   Telephone Purchases. Your account is automatically authorized to have the 
telephone purchase privilege unless you indicate otherwise on your Account 
Application or by writing to Pioneering Services Corporation ("PSC"). The 
telephone purchase option may be used to purchase additional shares for an 
existing Pioneer mutual fund account; it may not be used to establish a new 
account. Proper account identification will be required for each telephone 
purchase. A maximum of $25,000 per account may be purchased by telephone each 
day. The telephone purchase privilege is available to Individual Retirement 
Accounts ("IRAs") but may not be available to other types of retirement plan 
accounts. Call PSC for more information. 
    

   
   You are strongly urged to consult with your financial representative prior 
to requesting a telephone purchase. To purchase shares by telephone, you must 
establish your bank account of record by completing the appropriate section 
of your Account Application or an Account Options Form. PSC will 
electronically debit the amount of each purchase from this predesignated bank 
account. Telephone purchases may not be made for 30 days after the 
establishment of your bank of record or any change to your bank information. 
    

   Telephone purchases will be priced at the net asset value plus any 
applicable sales charge next determined after PSC's receipt of a telephone 
purchase instruction and receipt of good funds (usually three days after the 
purchase instruction). You may always elect to deliver purchases to PSC by 
mail. See "Telephone Transactions and Related Liabilities" for additional 
information.

   The schedule of sales charges above is applicable to purchases of Class A 
shares of the Fund by (i) an individual, (ii) an individual and his or her 
spouse and children under the age of 21 and (iii) a trustee or other 
fiduciary of a trust estate or fiduciary account or related trusts or 
accounts including pension, profit-sharing and other employee benefit trusts 
qualified under Section 401 or 408 of the Code, although more than one 
beneficiary is involved. The sales charges applicable to a current purchase 
of Class A shares of the Fund by a person listed above is determined by 
adding the value of shares to be purchased to the aggregate value (at the 
then current offering price) of shares of any of the other Pioneer mutual 
funds previously purchased and then owned, provided PFD is notified by such 
person or his or her broker-dealer each time a purchase is made which would 
qualify. Pioneer mutual funds include all mutual funds for which PFD serves 
as principal underwriter. See the "Letter of Intention" section of the 
Account Application. 
    

   
   No sales charge is payable at the time of purchase on investments of $1 
million or more or for purchases by participants in certain group plans 
(described below) subject to a CDSC of 1% which may be imposed in the event 
of a redemption of Class A shares within 12 months of purchase. See "How to 
Sell Fund Shares." PFD may, in its discretion, pay a commission to broker- 
dealers who initiate and are responsible for such purchases as follows: 1% on 
the first $5 million invested; 0.50% on the next $45 million; and 0.25% on 
the excess over $50 million. These commissions will not be paid if the 
purchaser is affiliated with the broker-dealer or if the purchase represents 
the reinvestment of a redemption made during the previous 12 calendar months. 
Broker-dealers who receive a commission in connection with Class A share 
purchases at net asset value by 401(a) or 401(k) retirement plans with 1,000 
or more eligible participants or with at least $10 million in plan assets 
will be required to return any commission paid or a pro rata portion thereof 
if the retirement plan redeems its shares within 12 months of purchase. See 
also "How to Sell Fund Shares." In connection with PGI's acquisition of FMC 
and contingent upon the achievement of certain sales objectives, PFD may pay 
to Mutual of Omaha Investor Services, Inc. 50% of PFD's retention of any 
sales commission on sales of the Fund's Class A shares through such dealer. 
From time to time, PFD may elect to reallow the entire initial sales charge 
to participating dealers for all Class A sales with respect to which orders 
are placed during a particular period. Dealers to whom substantially the 
entire sales charge is reallowed may be deemed to be underwriters under the 
federal securities laws. 
    

   Qualifying for a Reduced Sales Charge. Class A shares of the Fund may be 
sold at a reduced or eliminated sales charge to certain group plans ("Group 
Plans") under which a sponsoring organization makes recommendations to, 
permits group solicitation of, or otherwise facilitates purchases by, its 
employees, members or participants. Class A shares of the Fund may be sold at 
net asset value without a sales charge to 401(k) retirement plans with 100 or 
more participants or at least $500,000 in plan assets. Information about such 
arrangements is available from PFD. 

   
   Class A shares of the Fund may also be sold at net asset value per share 
without a sales charge to: (a) current or former Trustees and officers of the 
Fund and partners and employees of its legal counsel; (b) current or former 
directors, officers, employees or sales representatives of PGI or its 
subsidiaries; (c) current or former directors, officers, employees or sales 
representatives of any subadviser or predecessor investment adviser to any 
investment company for which PMC serves as investment adviser, and the 
subsidiaries or affiliates of such persons; (d) current or former officers, 
partners, employees or registered representatives of broker-dealers which 
have entered into sales agreements with PFD; (e) members of the immediate 
families of any of the persons above; (f) any trust, custodian, pension, 
profit-sharing or other benefit plan of the foregoing persons; (g) insurance 
company separate accounts; (h) certain "wrap accounts" for the benefit of 
clients of financial planners adhering to standards established by PFD; (i) 
other funds and accounts for which PMC or any of its affiliates serves as 
investment adviser or manager; and (j) certain unit investment trusts. Shares 
so purchased are purchased for investment purposes and may not be resold 
except through redemption or repurchase by or on behalf of the Fund. The 
availability of this privilege is conditioned upon the receipt by PFD of 
written notification of eligibility. Class A shares of the Fund may be sold 
at net asset value per share without a sales charge to Optional Retirement 
Program (the "Program") participants if (i) the employer has authorized a 
limited number of investment company providers for the Program, (ii) all 
authorized investment company providers offer their shares to Program 
participants at net asset value, (iii) the employer has agreed in writing to 
actively promote the authorized investment providers to Program participants 
and (iv) the Program provides for a matching contribution for each 
participant contribution. Shares of the Fund may also be sold at net asset 
value without a sales charge in connection with certain reorganization, 
liquidation or acquisition transactions involving other investment companies 
or personal holding companies. 
    

   Reduced sales charges for Class A shares are available through an 
agreement to purchase a specified quantity of Fund shares over a designated 
13-month period by completing the "Letter of Intention" section of the 
Account Application. Information about the Letter of Intention procedure, 
including its terms, is contained in the Statement of Additional Information. 
Investors who are clients of a broker-dealer with a current sales agreement 
with PFD may purchase Class A shares of the Fund at net asset value, without 
a sales charge, to the extent that the purchase price is paid out of proceeds 
from one or more redemptions by the investor of shares of certain other 
mutual funds. In order for a purchase to qualify for this privilege, the 
investor must document to the broker-dealer that the redemption occurred 
within the 60 days immediately preceding the purchase of Class A shares; that 
the client paid a sales charge on the original purchase of the shares 
redeemed; and that the mutual fund whose shares were redeemed also offers net 
asset value purchases to redeeming shareholders of any of the Pioneer mutual 
funds. Further details may be obtained from PFD. 

Class B Shares 

   You may buy Class B shares at net asset value per share next computed 
after receipt of a purchase order without the imposition of an initial sales 
charge; however, Class B shares redeemed within six years of purchase will be 
subject to a 

                                       9
<PAGE> 

CDSC at the rates shown in the table below. The charge will be assessed on 
the amount equal to the lesser of the current market value or the original 
purchase cost of the shares being redeemed. No CDSC will be imposed on 
increases in account value above the initial purchase price, including shares 
derived from the reinvestment of dividends or capital gains distributions. 

   The amount of the CDSC, if any, will vary depending on the number of years 
from the time of purchase until the time of redemption of Class B shares. For 
the purpose of determining the number of years from the time of any purchase, 
all payments during a quarter will be aggregated and deemed to have been made 
on the first day of that quarter. In processing redemptions of Class B 
shares, the Fund will first redeem shares not subject to any CDSC, and then 
shares held longest during the six-year period. As a result, you will pay the 
lowest possible CDSC. 

   
   The CDSC for Class B shares subject to a CDSC upon redemption will be 
determined as follows: 

                                CDSC as a Percentage 
Year Since                        of Dollar Amount 
Purchase                           Subject to CDSC 
 ---------------------------   ------------------------ 
First                                    4.0% 
Second                                   4.0% 
Third                                    3.0% 
Fourth                                   3.0% 
Fifth                                    2.0% 
Sixth                                    1.0% 
Seventh and thereafter                   none 
    

   Proceeds from the CDSC are paid to PFD and are used in whole or in part to 
defray PFD's expenses related to providing distribution-related services to 
the Fund in connection with the sale of Class B shares, including the payment 
of compensation to broker-dealers. 

   Class B shares will automatically convert into Class A shares at the end 
of the calendar quarter that is eight years after the purchase date, except 
as noted below. Class B shares acquired by exchange from Class B shares of 
another Pioneer mutual fund will convert into Class A shares based on the 
date of the initial purchase and the applicable CDSC. Class B shares acquired 
through reinvestment of distributions will convert into Class A shares based 
on the date of the initial purchase to which such shares relate. For this 
purpose, Class B shares acquired through reinvestment of distributions will 
be attributed to particular purchases of Class B shares in accordance with 
such procedures as the Trustees may determine from time to time. The 
conversion of Class B shares to Class A shares is subject to the continuing 
availability of a ruling from the Internal Revenue Service ("IRS"), for which 
the Fund is applying, or an opinion of counsel that such conversions will not 
constitute taxable events for federal tax purposes. There can be no assurance 
that such ruling or opinion will be available. The conversion of Class B 
shares to Class A shares will not occur if such ruling or opinion is not 
available and, therefore, Class B shares would continue to be subject to 
higher expenses than Class A shares for an indeterminate period. 

Class C Shares 

   
   You may buy Class C shares at net asset value without the imposition of an 
initial sales charge; however, Class C shares redeemed within one year of 
purchase will be subject to a CDSC of 1%. The charge will be assessed on the 
amount equal to the lesser of the current market value or the original 
purchase cost of the shares being redeemed. No CDSC will be imposed on 
increases in account value above the initial purchase price, including shares 
derived from the reinvestment of dividends or capital gains distributions. 
Class C shares do not convert to any other Class of Fund shares. 
    

   For the purpose of determining the time of any purchase, all payments 
during a quarter will be aggregated and deemed to have been made on the first 
day of that quarter. In processing redemptions of Class C shares, the Fund 
will first redeem shares not subject to any CDSC, and then shares held for 
the shortest period of time during the one-year period. As a result, you will 
pay the lowest possible CDSC. 

   Proceeds from the CDSC are paid to PFD and are used in whole or in part to 
defray PFD's expenses related to providing distribution-related services to 
the Fund in connection with the sale of Class C shares, including the payment 
of compensation to broker-dealers. 

   
All Classes of Shares 
    

Waiver or Reduction of Contingent Deferred Sales Charge 

   The CDSC on Class B shares may be waived or reduced for non-retirement 
accounts if: (a) the redemption results from the death of all registered 
owners of an account (in the case of UGMAs, UTMAs and trust accounts, the 
waiver applies upon the death of all beneficial owners) or a total and 
permanent disability (as defined in Section 72 of the Code) of all registered 
owners occurring after the purchase of the shares being redeemed or (b) the 
redemption is made in connection with limited automatic redemptions as set 
forth in "Systematic Withdrawal Plans" (limited in any year to 10% of the 
value of the account in the Fund at the time the withdrawal plan is 
established). 

   The CDSC on Class B shares may be waived or reduced for retirement plan 
accounts if: (a) the redemption results from the death or a total and 
permanent disability (as defined in Section 72 of the Code) occurring after 
the purchase of the shares being redeemed of a shareholder or participant in 
an employer- sponsored retirement plan; (b) the distribution is to a 
participant in an IRA, 403(b) or employer-sponsored retirement plan, is part 
of a series of substantially equal payments made over the life expectancy of 
the participant or the joint life expectancy of the participant and his or 
her beneficiary or as scheduled periodic payments to a participant (limited 
in any year to 10% of the value of the participant's account at the time the 
distribution amount is established; a required minimum distribution due to 
the participant's attainment of age 70-1/2 may exceed the 10% limit only if 
the distribution amount is based on plan assets held by Pioneer); (c) the 
distribution is from a 401(a) or 401(k) retirement plan and is a return of 
excess employee deferrals or employee contributions or a qualifying hardship 
distribution as defined by the Code or results from a termination of 
employment (limited with respect to a termination to 10% per year of the 
value of the plan's assets in the Fund as of the later of the prior December 
31 or the date the account was established unless the plan's assets are being 
rolled over to or reinvested in the same class of shares of a Pioneer mutual 
fund subject to 

                                       10
<PAGE> 

the CDSC of the shares originally held); (d) the distribution is from an IRA, 
403(b) or employer-sponsored retirement plan and is to be rolled over to or 
reinvested in the same class of shares in a Pioneer mutual fund and which 
will be subject to the applicable CDSC upon redemption; (e) the distribution 
is in the form of a loan to a participant in a plan which permits loans (each 
repayment of the loan will constitute a new sale which will be subject to the 
applicable CDSC upon redemption); or (f) the distribution is from a qualified 
defined contribution plan and represents a participant's directed transfer 
(provided that this privilege has been pre-authorized through a prior 
agreement with PFD regarding participant directed transfers). 

   
   The CDSC on Class C shares and on any Class A shares subject to a CDSC may 
be waived or reduced as follows: (a) for automatic redemptions as described 
in "Systematic Withdrawal Plans" (limited to 10% of the value of the 
account); (b) if the redemption results from the death or a total and 
permanent disability (as defined in Section 72 of the Code) occurring after 
the purchase of the shares being redeemed of a shareholder or participant in 
an employer-sponsored retirement plan; (c) if the distribution is part of a 
series of substantially equal payments made over the life expectancy of the 
participant or the joint life expectancy of the participant and his or her 
beneficiary; or (d) if the distribution is to a participant in an 
employer-sponsored retirement plan and is (i) a return of excess employee 
deferrals or contributions, (ii) a qualifying hardship distribution as 
defined by the Code, (iii) from a termination of employment, (iv) in the form 
of a loan to a participant in a plan which permits loans, or (v) from a 
qualified defined contribution plan and represents a participant's directed 
transfer (provided that this privilege has been pre- authorized through a 
prior agreement with PFD regarding participant directed transfers). 
    

   The CDSC on Class B and Class C shares and on any Class A shares subject 
to a CDSC may be waived or reduced for either non-retirement or retirement 
plan accounts if: (a) the redemption is made by any state, county, or city, 
or any instrumentality, department, authority, or agency thereof, which is 
prohibited by applicable laws from paying a CDSC in connection with the 
acquisition of shares of any registered investment management company; or (b) 
the redemption is made pursuant to each Fund's right to liquidate or 
involuntarily redeem shares in a shareholder's account. 

Broker-Dealers 

   
   An order for any Class of Fund shares received by PFD from a broker-dealer 
prior to the close of regular trading on the Exchange is confirmed at the 
price appropriate for that Class as determined at the close of regular 
trading on the Exchange on the day the order is received, provided the order 
is received by PFD prior to PFD's close of business (usually, 5:30 p.m. 
Eastern Time). It is the responsibility of broker-dealers to transmit orders 
so that they will be received by PFD prior to its close of business. PFD or 
its affiliates may provide additional compensation to certain dealers or such 
dealers' affiliates based on certain objective criteria established from time 
to time by PFD. All such payments are made out of PFD's or the affiliate's 
own assets. These payments will not change the price an investor will pay for 
shares or the amount that the Fund will receive from such sale. 
    

General 

   The Fund reserves the right in its sole discretion to withdraw all or any 
part of the offering of shares when, in the judgment of the Fund's 
management, such withdrawal is in the best interest of the Fund. An order to 
purchase shares is not binding on, and may be rejected by, PFD until it has 
been confirmed in writing by PFD and payment has been received. 

VIII. HOW TO SELL FUND SHARES 

   You can arrange to sell (redeem) Fund shares on any day the Exchange is 
open by selling either some or all of your shares to the Fund. 

   You may sell your shares either through your broker-dealer or directly to 
the Fund. Please note the following: 

(bullet) If you are selling shares from a retirement account, you must make 
         your request in writing (except for exchanges to other Pioneer 
         mutual funds which can be requested by phone or in writing). Call 
         1-800-622-0176 for more information. 

(bullet) If you are selling shares from a non-retirement account, you may use 
         any of the methods described below. 

   Your shares will be sold at the share price next calculated after your 
order is received in good order less any applicable CDSC. Sale proceeds 
generally will be sent to you in cash, normally within seven days after your 
order is received in good order. The Fund reserves the right to withhold 
payment of the sale proceeds until checks received by the Fund in payment for 
the shares being sold have cleared, which may take up to 15 calendar days 
from the purchase date. 

In Writing 

   
   You may sell your shares by delivering a written request, signed by all 
registered owners, in good order to PSC, however, you must use a written 
request, including a signature guarantee, to sell your shares if any of the 
following applies: 
    

(bullet) you wish to sell over $50,000 worth of shares, 

(bullet) your account registration or address has changed within the last 30 
         days, 

(bullet) the check is not being mailed to the address on your account 
         (address of record), 

(bullet) the check is not being made out to the account owners, or 

(bullet) the sale proceeds are being transferred to a Pioneer account with a 
         different registration. 

   
   Your request should include your name, the Fund's name, your fund account 
number, the Class of shares to be redeemed, the dollar amount or number of 
shares to be redeemed, and any other applicable requirements as described 
below. Unless instructed otherwise, PSC will send the proceeds of the sale to 
the address of record. Fiduciaries and corporations are required to submit 
additional documents. For more information, contact PSC at 1-800-225-6292. 
    

   
   Written requests will not be processed until they are received in good 
order by PSC. Good order means that there are no outstanding claims or 
requests to hold redemptions on the account, certificates are endorsed by the 
record own- 
    

                                       11
<PAGE> 

   
er(s) exactly as the shares are registered and the signature(s) are 
guaranteed by an eligible guarantor. You should be able to obtain a signature 
guarantee from a bank, broker, dealer, credit union (if authorized under 
state law), securities exchange or association, clearing agency or savings 
association. A notary public cannot provide a signature guarantee. Signature 
guarantees are not accepted by facsimile ("fax"). For additional information 
about the necessary documentation for redemption by mail, please contact PSC 
at 1-800-225-6292. 
    

   
    By Telephone or by Fax. Your account is automatically authorized to have 
the telephone redemption privilege unless you indicate otherwise on your 
Account Application or by writing to PSC. Proper account identification will 
be required for each telephone redemption. A maximum of $50,000 per account 
per day may be redeemed by telephone or fax and receive the proceeds by check 
or bank wire or electronic funds transfer. To receive the proceeds by check: 
the check must be made payable exactly as the account is registered and the 
check must be sent to the address of record which must not have changed in 
the last 30 days. To receive the proceeds by bank wire or by electronic funds 
transfer: the proceeds must be sent to your bank address of record which must 
have been properly predesignated either on your Account Application or on an 
Account Options Form and which must not have changed in the last 30 days. To 
redeem by fax send your redemption request to 1-800-225-4240. You may always 
elect to deliver redemption instructions to PSC by mail. See "Telephone 
Transactions and Related Liabilities" below. Telephone and fax redemptions 
will be priced as described above. You are strongly urged to consult with 
your financial representative prior to requesting a telephone redemption. 
    

   Selling Shares Through Your Broker-Dealer. The Fund authorized PFD to act 
as its agent in the repurchase of shares of the Fund from qualified 
broker-dealers and reserves the right to terminate this procedure at any 
time. Your broker-dealer must receive your request before the close of 
business on the Exchange and transmit it to PFD before PFD's close of 
business to receive that day's redemption price. Your broker-dealer is 
responsible for providing all necessary documentation to PFD and may charge 
you for its services. 

   Small Accounts. The minimum account value is $500. If you hold shares of 
the Fund in an account with a net asset value of less than the minimum 
required amount due to redemptions or exchanges, the Fund may redeem the 
shares held in this account at net asset value if you have not increased the 
net asset value of the account to at least the minimum required amount within 
six months of notice by the Fund to you of the Fund's intention to redeem the 
shares. 

   
   CDSC on Class A Shares. Purchases of Class A shares of $1 million or more, 
or by participants in a Group Plan which were not subject to an initial sales 
charge, may be subject to a CDSC upon redemption. A CDSC is payable to PFD on 
these investments in the event of a share redemption within 12 months 
following the share purchase, at the rate of 1% of the lesser of the value of 
the shares redeemed (exclusive of reinvested dividend and capital gain 
distributions) or the total cost of such shares. Shares subject to the CDSC 
which are exchanged into another Pioneer mutual fund will continue to be 
subject to the CDSC until the original 12-month period expires. However, no 
CDSC is payable upon redemption with respect to Class A shares purchased by 
401(a) or 401(k) retirement plans with 1,000 or more eligible participants or 
with at least $10 million in plan assets. 
    

   General. Redemptions may be suspended or payment postponed during any 
period in which any of the following conditions exist: the Exchange is closed 
or trading on the Exchange is restricted; an emergency exists as a result of 
which disposal by the Fund of securities owned by it is not reasonably 
practicable or it is not reasonably practicable for the Fund to fairly 
determine the value of the net assets of its portfolio; or the SEC, by order, 
so permits. 

   Redemptions and repurchases are taxable transactions to shareholders. The 
net asset value per share received upon redemption or repurchase may be more 
or less than the cost of shares to an investor, depending on the market value 
of the portfolio at the time of redemption or repurchase. 

IX. HOW TO EXCHANGE FUND SHARES 

   
    Written Exchanges. You may exchange your shares by sending a letter of 
instruction to PSC. Your letter should include your name, the name of the 
Fund out of which you wish to exchange and the name of the Pioneer mutual 
fund into which you wish to exchange, your fund account number(s), the Class 
of shares to be exchanged and the dollar amount or number of shares to be 
exchanged. Written exchange requests must be signed by all record owner(s) 
exactly as the shares are registered. 
    

   
    Telephone Exchanges. Your account is automatically authorized to have the 
telephone exchange privilege unless you indicate otherwise on your Account 
Application or by writing to PSC. Proper account identification will be 
required for each telephone exchange. Telephone exchanges may not exceed 
$500,000 per account per day. Each telephone exchange request, whether by 
voice or by FactFone(SM), will be recorded. You are strongly urged to consult 
with your financial representative prior to requesting a telephone exchange. 
See "Telephone Transactions and Related Liabilities" below. 
    

   
    Automatic Exchanges. You may automatically exchange shares from one 
Pioneer mutual fund account for shares of the same Class in another Pioneer 
mutual fund account on a monthly or quarterly basis. The accounts must have 
identical registrations and the originating account must have a minimum 
balance of $5,000. The exchange will be effective on the day of the month 
designated on your Account Application or Account Options Form. 
    

   
   General. Exchanges must be at least $1,000. You may exchange your 
investment from one Class of fund shares at net asset value, without a sales 
charge, for shares of the same Class of any other Pioneer mutual fund. Not 
all Pioneer mutual funds offer more than one Class of shares. A new Pioneer 
mutual fund account opened through an exchange must have a registration 
identical to that on the original account. 
    

                                       12
<PAGE> 

   Shares which would normally be subject to a CDSC upon redemption will not 
be charged the applicable CDSC at the time of an exchange. Shares acquired in 
an exchange will be subject to the CDSC of the shares originally held. For 
purposes of determining the amount of any applicable CDSC, the length of time 
you have owned shares acquired by exchange will be measured from the date you 
acquired the original shares and will not be affected by any subsequent 
exchange. 

   
   Exchange requests received by PSC before 4:00 p.m. Eastern Time will be 
effective on that day if the requirements above have been met, otherwise, 
they will be effective on the next business day. PSC will process exchanges 
only after receiving an exchange request in good order. There are currently 
no fees or sales charges imposed at the time of an exchange. An exchange of 
shares may be made only in states where legally permitted. For federal and 
(generally) state income tax purposes, an exchange is considered to be a sale 
of the shares of the fund exchanged and a purchase of shares in another 
Pioneer mutual fund. Therefore, an exchange could result in a gain or loss on 
the shares sold, depending on the tax basis of these shares and the timing of 
the transaction, and special tax rules may apply. 
    

   You should consider the differences in objectives and policies of the 
Pioneer mutual funds, as described in each fund's current prospectus, before 
making any exchange. For the protection of the Fund's performance and 
shareholders, the Fund and PFD reserve the right to refuse any exchange 
request or restrict, at any time without notice, the number and/or frequency 
of exchanges to prevent abuses of the exchange privilege. Such abuses may 
arise from frequent trading in response to short- term market fluctuations, a 
pattern of trading by an individual or group that appears to be an attempt to 
"time the market," or any other exchange request which, in the view of 
management, will have a detrimental effect on the Fund's portfolio management 
strategy or its operations. In addition, the Fund and PFD reserve the right 
to charge a fee for exchanges or to modify, limit, suspend or discontinue the 
exchange privilege with notice to shareholders as required by law. 

X. DISTRIBUTION PLANS 

   The Fund has adopted a Plan of Distribution for each Class of shares (the 
"Class A Plan," "Class B Plan," and "Class C Plan") in accordance with Rule 
12b-1 under the 1940 Act pursuant to which certain distribution and service 
fees are paid. 

   Pursuant to the Class A Plan, the Fund reimburses PFD for its actual 
expenditures to finance any activity primarily intended to result in the sale 
of Class A shares or to provide services to holders of Class A shares, 
provided the categories of expenses for which reimbursement is made are 
approved by the Fund's Board of Trustees. As of the date of this Prospectus, 
the Board of Trustees has approved the following categories of expenses for 
Class A shares of the Fund: (i) a service fee to be paid to qualified 
broker-dealers in an amount not to exceed 0.25% per annum of the Fund's 
average daily net assets attributable to Class A shares; (ii) reimbursement 
to PFD for its expenditures for broker-dealer commissions and employee 
compensation on certain sales of the Fund's Class A shares with no initial 
sales charge (See "How to Buy Fund Shares"); and (iii) reimbursement to PFD 
for expenses incurred in providing services to Class A shareholders and 
supporting broker-dealers and other organizations (such as banks and trust 
companies) in their efforts to provide such services. Banks are currently 
prohibited under the Glass-Steagall Act from providing certain underwriting 
or distribution services. If a bank was prohibited from acting in any 
capacity or providing any of the described services, management would 
consider what action, if any, would be appropriate. 

   Expenditures of the Fund pursuant to the Class A Plan are accrued daily 
and may not exceed 0.25% of the Fund's average daily net assets attributable 
to Class A shares. Distribution expenses of PFD are expected to substantially 
exceed the distribution fees paid by the Fund in a given year. The Class A 
Plan may not be amended to increase materially the annual percentage 
limitation of average net assets which may be spent for the services 
described therein without approval of the Fund's Class A shareholders. 

   Both the Class B Plan and the Class C Plan provide that the Fund will pay 
a distribution fee at the annual rate of 0.75% of the Fund's average daily 
net assets attributable to the applicable Class of shares and will pay PFD a 
service fee at the annual rate of 0.25% of the Fund's average daily net 
assets attributable to that Class of shares. The distribution fee is intended 
to compensate PFD for its distribution services to the Fund. The service fee 
is intended to be additional compensation for personal services and/or 
account maintenance services with respect to Class B and Class C shares. PFD 
also receives the proceeds of any CDSC imposed on the redemption of Class B 
and Class C shares. 

   Commissions of 4%, equal to 3.75% of the amount invested and a first 
year's service fee equal to 0.25% of the amount invested in Class B shares, 
are paid to broker- dealers who have selling agreements with PFD. PFD may 
advance to dealers the first year service fee at a rate up to 0.25% of the 
purchase price of such shares and, as compensation therefore, PFD may retain 
the service fee paid by the Fund with respect to such shares for the first 
year after purchase. Dealers will become eligible for additional service fees 
with respect to such shares commencing in the 13th month following the 
purchase. Commissions of up to 1% of the amount invested in Class C shares, 
consisting of 0.75% of the amount invested and a first year's service fee of 
0.25% of the amount invested, are paid to broker-dealers who have selling 
agreements with PFD. PFD may advance to dealers the first year service fee at 
a rate up to 0.25% of the purchase price of such shares and, as compensation 
therefor, PFD may retain the service fee paid by the Fund with respect to 
such shares for the first year after purchase. Commencing in the 13th month 
following the purchase of Class C shares, dealers will become eligible for 
additional annual distribution fees and service fees of up to 0.75% and 
0.25%, respectively, of the net asset value of such shares. Dealers may from 
time to time be required to meet certain criteria in order to receive service 
fees. PFD or its affiliates are entitled to retain all service fees payable 
under the Class B Plan or the Class C Plan for which there is no dealer of 
record or for which qualification standards have not been met as partial 
consideration for per- 

                                       13
<PAGE> 

sonal services and/or account maintenance services performed by PFD or its 
affiliates for shareholder accounts. 

XI. DIVIDENDS, DISTRIBUTIONS AND TAXATION 

   The Fund has elected to be treated, has qualified, and intends to qualify 
each year as a "regulated investment company" under Subchapter M of the Code, 
so that it will not pay federal income taxes on income and capital gains 
distributed to shareholders at least annually. 

   
   Under the Code, the Fund will be subject to a nondeductible 4% federal 
excise tax on a portion of its undistributed ordinary income and capital 
gains if it fails to meet certain distribution requirements with respect to 
each calendar year. The Fund intends to make distributions in a timely manner 
and accordingly does not expect to be subject to the excise tax. 
    

   
   The Fund's policy is to pay to shareholders dividends from net investment 
income, if any, and to make distributions from net long-term capital gains, 
if any, usually in December. Distributions from net short-term capital gains, 
if any, may be paid with such dividends; distributions of dividends from 
income and/or capital gains may also be made at such other times as may be 
necessary to avoid federal income or excise tax. Dividends from the Fund's 
net investment income, net short- term capital gains, and certain net foreign 
exchange gains are taxable as ordinary income, and dividends from the Fund's 
net long-term capital gains are taxable as long-term capital gains. 
    

   Unless shareholders specify otherwise, all distributions will be 
automatically reinvested in additional full and fractional shares of the 
Fund. For federal income tax purposes, all dividends are taxable as described 
above whether a shareholder takes them in cash or reinvests them in 
additional shares of the Fund. Information as to the federal tax status of 
dividends and distributions will be provided annually to shareholders. For 
further information on the distribution options available to shareholders, 
see "Distribution Options" and "Directed Dividends" below. 

   Distributions by the Fund of the dividend income it receives from U.S. 
domestic corporations, if any, may qualify for the corporate 
dividends-received deduction for corporate shareholders, subject to minimum 
holding-period requirements and debt-financing restrictions under the Code. 

   The Fund may be subject to foreign withholding taxes or other foreign 
taxes on income (possibly including, in some cases, capital gains) from 
certain foreign investments, which will reduce its return from those 
investments. The Fund will not qualify to pass such taxes through to its 
shareholders, who accordingly will neither treat such taxes as additional 
income nor be entitled to any foreign tax credits or deductions with respect 
to such taxes. 

   Dividends and other distributions and the proceeds of redemptions, 
exchanges or repurchases of Fund shares paid to individuals and other 
non-exempt payees will be subject to 31% backup withholding of federal income 
tax if the Fund is not provided with the shareholder's correct taxpayer 
identification number and certification that the number is correct and the 
shareholder is not subject to backup withholding or if the Fund receives 
notice from the IRS or a broker that such withholding applies. Please refer 
to the Account Application for additional information. 

   The description above relates only to U.S. federal income tax consequences 
for shareholders who are U.S. persons, i.e., U.S. citizens or residents or 
U.S. corporations, partnerships, trusts or estates and who are subject to 
U.S. federal income tax. Non-U.S. shareholders and tax-exempt shareholders 
are subject to different tax treatment that is not described above. 
Shareholders should consult their own tax advisers regarding state, local and 
other applicable tax laws. 

XII. SHAREHOLDER SERVICES 

   PSC is the shareholder services and transfer agent for shares of the Fund. 
PSC, a Massachusetts corporation, is a wholly-owned subsidiary of PGI. PSC's 
offices are located at 60 State Street, Boston, Massachusetts 02109, and 
inquiries to PSC should be mailed to Pioneering Services Corporation, P.O. 
Box 9014, Boston, Massachusetts 02205-9014. Brown Brothers Harriman & Co. 
(the "Custodian") serves as custodian of the Fund's portfolio securities and 
other assets. The principal business address of the mutual fund division of 
the Custodian is 40 Water Street, Boston, Massachusetts 02109. 

Account and Confirmation Statements 

   
   PSC maintains an account for each shareholder and all transactions of the 
shareholder are recorded in this account. Confirmation statements showing 
details of transactions are sent to shareholders as transactions occur, 
except Automatic Investment Plan transactions which are confirmed quarterly. 
The Pioneer Combined Account Statement, mailed quarterly, is available to 
shareholders who have more than one Pioneer mutual fund account. 
    

   
   Shareholders whose shares are held in the name of an investment 
broker-dealer or other party will not normally have an account with the Fund 
and might not be able to utilize some of the services available to 
shareholders of record. Examples of services which might not be available are 
purchases, exchanges or redemptions of shares by mail or telephone, automatic 
reinvestment of dividends and capital gains distributions, withdrawal plans, 
Letters of Intention, Rights of Accumulation and newsletters. 
    

Additional Investments 

   
   You may add to your account by sending a check (minimum of $50 for Class A 
shares and $500 for Class B and Class C shares) to PSC (account number and 
Class of shares should be clearly indicated). The bottom portion of a 
confirmation statement may be used as a remittance slip to make additional 
investments. 
    

   
   Additions to your account, whether by check or through a Pioneer 
Investomatic Plan, are invested in full and fractional shares of the Fund at 
the applicable offering price in effect as of the close of regular trading on 
the Exchange on the day of receipt. 
    

Automatic Investment Plans 

   
   You may arrange for regular automatic investments of $50 or more through 
government/military allotments, payroll deduction or through a Pioneer 
Investomatic Plan. A Pioneer 
    

                                       14
<PAGE> 

   
Investomatic Plan provides for a monthly or quarterly investment by means of 
a pre-authorized electronic funds transfer or draft drawn on a checking 
account. Pioneer Investomatic Plan investments are voluntary, and you may 
discontinue the Plan at any time without penalty upon 30 days' written notice 
to PSC. PSC acts as agent for the purchaser, the broker- dealer and PFD in 
maintaining these plans. 
    

Financial Reports and Tax Information 

   As a shareholder, you will receive financial reports at least 
semiannually. In January of each year, the Fund will mail you information 
about the tax status of dividends and distributions. 

Distribution Options 

   
   Dividends and capital gains distributions, if any, will automatically be 
invested in additional shares of the Fund, at the applicable net asset value 
per share, unless you indicate another option on the Account Application. Two 
other options available are (a) dividends in cash and capital gains 
distributions in additional shares; and (b) all dividends and capital gains 
distributions in cash. These two options are not available, however, for 
retirement plans or for an account with a net asset value of less than $500. 
Changes in your distribution options may be made by written request to PSC. 
    

Directed Dividends 

   You may elect (in writing) to have the dividends paid by one Pioneer 
mutual fund account invested in a second Pioneer mutual fund account. The 
value of this second account must be at least $1,000 ($500 for Pioneer Fund 
or Pioneer II). Invested dividends may be in any amount, and there are no 
fees or charges for this service. Retirement plan shareholders may only 
direct dividends to accounts with identical registrations, i.e., PGI IRA Cust 
for John Smith may only go into another account registered PGI IRA Cust for 
John Smith. 

Direct Deposit 

   If you have elected to take distributions, whether dividends or dividends 
and capital gains, in cash, or have established a Systematic Withdrawal Plan, 
you may choose to have those cash payments deposited directly into your 
savings, checking or NOW bank account. You may establish this service by 
completing the appropriate section on the Account Application when opening a 
new account or the Account Options Form for an existing account. 

Voluntary Tax Withholding 

   You may request (in writing) that PSC withhold 28% of the dividends and 
capital gains distributions paid from your account (before any reinvestment) 
and forward the amount withheld to the IRS as a credit against your federal 
income taxes. This option is not available for retirement plan accounts or 
for accounts subject to backup withholding. 

Telephone Transactions and Related Liabilities 

   
   Your account is automatically authorized to have telephone transaction 
privileges unless you indicate otherwise on your Account Application or by 
writing to PSC. You may purchase, sell or exchange Fund shares by telephone. 
See "How to Buy Fund Shares," "How to Sell Fund Shares" and "How to Exchange 
Fund Shares" for more information. For personal assistance, call 
1-800-225-6292 between 8:00 a.m. and 9:00 p.m. Eastern Time on weekdays. 
Computer-assisted transactions may be available to shareholders who have pre- 
recorded certain bank information (see "FactFone(SM)"). You are strongly 
urged to consult with your financial representative prior to requesting any 
telephone transaction. To confirm that each transaction instruction received 
by telephone is genuine, PSC will record each telephone transaction, require 
the caller to provide the personal identification number ("PIN") for the 
account and send you a written confirmation of each telephone transaction. 
Different procedures may apply to accounts that are registered to non-U.S. 
citizens or that are held in the name of an institution or in the name of an 
investment broker-dealer or other third party. If reasonable procedures, such 
as those described above, are not followed, the Fund may be liable for any 
loss due to unauthorized or fraudulent instructions. The Fund may implement 
other procedures from time to time. In all other cases, neither the Fund, PSC 
nor PFD will be responsible for the authenticity of instructions received by 
telephone, therefore, you bear the risk of loss for unauthorized or 
fraudulent telephone transactions. 
    

   During times of economic turmoil or market volatility or as a result of 
severe weather or a natural disaster, it may be difficult to contact the Fund 
by telephone to institute a redemption or exchange. You should communicate 
with the Fund in writing if you are unable to reach the Fund by telephone. 

FactFone(SM) 

   
   FactFone(SM) is an automated inquiry and telephone transaction system 
available to Pioneer shareholders by dialing 1-800-225-4321. FactFone(SM) 
allows you to obtain current information on your Pioneer mutual fund accounts 
and to inquire about the prices and yields of all publicly available Pioneer 
mutual funds. In addition, you may use FactFone(SM) to make computer-assisted 
telephone purchases, exchanges and redemptions from your Pioneer mutual fund 
accounts if you have activated your PIN. Telephone purchases and redemptions 
require the establishment of a bank account of record. You are strongly urged 
to consult with your financial representative prior to requesting any 
telephone transaction. Shareholders whose accounts are registered in the name 
of a broker-dealer or other third party may not be able to use FactFone(SM). 
See "How to Buy Fund Shares," "How to Exchange Fund Shares," "How to Sell 
Fund Shares" and "Telephone Transactions and Related Liabilities." Call PSC 
for assistance. 
    

Retirement Plans 

   
   You should contact the Retirement Plans Department of PSC at 
1-800-622-0176 for information relating to retirement plans for businesses, 
age-weighted profit sharing plans, Simplified Employee Pension Plans, IRAs, 
and Section 403(b) retirement plans for employees of certain non-profit 
organizations and public school systems, all of which are available in 
conjunction with investments in the Fund. The Pioneer Mutual Funds Account 
Application accompanying this Prospectus should not be used to establish any 
of these plans. Separate applications are required.

Telecommunications Device for the Deaf (TDD) 

   
   If you have a hearing disability and access to TDD keyboard equipment, you 
can call our TDD number toll-free at 1-800-622-1997, weekdays from 8:30 a.m. 
to 5:30 p.m. Eastern Time to contact our telephone representatives with 
questions about your account. 
    

Systematic Withdrawal Plans 

   
   If your account has a total value of at least $10,000 you may establish a 
Systematic Withdrawal Plan ("SWP") providing for fixed payments at regular 
intervals. Withdrawals from Class B and Class C share accounts are limited to 
10% of the value of the account at the time the SWP is implemented. See 
"Waiver or Reduction of Contingent Deferred Sales Charge" for more 
information. Periodic checks of $50 or more will be sent to you, or any 
person designated by you, monthly or quarterly, and your periodic redemptions 
of shares may be taxable to you. Payments can be made either by check or 
electronic transfer to a bank account designated by you. If you direct that 
withdrawal checks be paid to another person after you have opened your 
account, a signature guarantee must accompany your instructions. Purchases of 
Class A shares of the Fund at a time when you have a SWP in effect may result 
in the payment of unnecessary sales charges and may therefore be 
disadvantageous. You may obtain additional information by calling PSC at 
1-800-225- 6292 or by referring to the Statement of Additional Information. 
    

Reinstatement Privilege (Class A Shares Only) 

   
   If you redeem all or part of your Class A shares of the Fund, you may 
reinvest all or part of the redemption proceeds without a sales charge in 
Class A shares of the Fund if you send a written request to PSC not more than 
90 days after your shares were redeemed. Your redemption proceeds will be 
reinvested at the next determined net asset value of the Class A shares of 
the Fund in effect immediately after receipt of the written request for 
reinstatement. You may realize a gain or loss for federal income tax purposes 
as a result of the redemption, and special tax rules may apply if a 
reinstatement occurs. In addition, if a redemption resulted in a loss and an 
investment is made in shares of the Fund within 30 days before or after the 
redemption, you may not be able to recognize the loss for federal income tax 
purposes. Subject to the provisions outlined under "How to Exchange Fund 
Shares" above, you may also reinvest in Class A shares of other Pioneer 
mutual funds; in this case you must meet the minimum investment requirements 
for each fund you enter. 
    

   The 90-day reinstatement period may be extended by PFD for periods of up 
to one year for shareholders living in areas that have experienced a natural 
disaster, such as a flood, hurricane, tornado, or earthquake. 

   The options and services available to shareholders, including the terms of 
the Exchange Privilege and the Pioneer Investomatic Plan, may be revised, 
suspended or terminated at any time by PFD or by the Fund. You may establish 
the services described in this section when you open your account. You may 
also establish or revise many of them on an existing account by completing an 
Account Options Form, which you may request by calling 1-800-225-6292. 

XIII. THE FUND 

   The Fund, an open-end, diversified management investment company (commonly 
referred to as a mutual fund), was established as a Nebraska corporation on 
January 16, 1968 and reorganized as a Delaware business trust on June 30, 
1994. The Fund has authorized an unlimited number of shares of beneficial 
interest. As an open-end management investment company, the Fund continuously 
offers its shares to the public and under normal conditions must redeem its 
shares upon the demand of any shareholder at the then current net asset value 
per share. See "How to Sell Fund Shares." The Fund is not required, and does 
not intend, to hold annual shareholder meetings although special meetings may 
be called for the purpose of electing or removing Trustees, changing 
fundamental investment restrictions or approving a management contract. 

   The Fund reserves the right to create and issue additional series of 
shares. The Trustees have the authority, without further shareholder 
approval, to classify and reclassify the shares of the Fund, or any new 
series, into one or more classes. As of the date of this Prospectus, the 
Trustees have authorized the issuance of three classes of shares, designated 
as Class A, Class B and Class C. The shares of each class represent an 
interest in the same portfolio of investments of the Fund. Each class has 
equal rights as to voting, redemption, dividends and liquidation, except that 
each class bears different distribution and transfer agent fees and may bear 
other expenses properly attributable to the particular class. Class A, Class 
B and Class C shareholders have exclusive voting rights with respect to the 
Rule 12b-1 distribution plans adopted by holders of those shares in 
connection with the distribution of shares. 

   In addition to the requirements under Delaware law, the Declaration of 
Trust provides that a shareholder of the Fund may bring a derivative action 
on behalf of the Fund only if the following conditions are met: (a) 
shareholders eligible to bring such derivative action under Delaware law who 
hold at least 10% of the outstanding shares of the Fund, or 10% of the 
outstanding shares of the series or class to which such action relates, shall 
join in the request for the Trustees to commence such action; and (b) the 
Trustees must be afforded a reasonable amount of time to consider such 
shareholder request and investigate the basis of such claim. The Trustees 
shall be entitled to retain counsel or other advisers in considering the 
merits of the request and shall require an undertaking by the shareholders 
making such request to reimburse the Fund for the expense of any such 
advisers in the event that the Trustees determine not to bring such action. 

   
   When issued and paid for in accordance with the terms of the Prospectus 
and Statement of Additional Information, shares of the Fund are fully-paid 
and non-assessable. Shares will remain on deposit with the Fund's transfer 
agent and certificates will not normally be issued. The Fund reserves the 
right to charge a fee for the issuance of Class A share certificates; 
certificates will not be issued for Class B or Class C shares. 
    

XIV. INVESTMENT RESULTS 

   The average annual total return (for a designated period of time) on an 
investment in the Fund may be included in advertisements, and furnished to 
existing or prospective shareholders. The average annual total return for 
each Class is computed in accordance with the SEC's standardized for- 

                                       16
<PAGE> 

mula. The calculation for all Classes assumes the reinvestment of all 
dividends and distributions at net asset value and does not reflect the 
impact of federal or state income taxes. In addition, for Class A shares the 
calculation assumes the deduction of the maximum sales charge of 5.75%; for 
Class B and Class C shares the calculation reflects the deduction of any 
applicable CDSC. The periods illustrated would normally include one, five and 
ten years (or since the commencement of the public offering of the shares of 
a Class, if shorter) through the most recent calendar quarter. 

   One or more additional measures and assumptions, including but not limited 
to historical total returns; distribution returns; results of actual or 
hypothetical investments; changes in dividends, distributions or share 
values; or any graphic illustration of such data may also be used. These data 
may cover any period of the Fund's existence and may or may not include the 
impact of sales charges, taxes or other factors. 

   Other investments or savings vehicles and/or unmanaged market indexes, 
indicators of economic activity or averages of mutual fund results may be 
cited or compared with the investment results of the Fund. Rankings or 
listings by magazines, newspapers or independent statistical or rating 
services, such as Lipper Analytical Services, Inc., may also be referenced. 

   The Fund's investment results will be calculated separately for each class 
of shares and will vary from time to time depending on market conditions, the 
composition of the Fund's portfolio, operating expenses of the Fund and 
expenses attributed to a specific class of Fund shares. All quoted investment 
results are historical and should not be considered representative of what an 
investment in the Fund may earn in any future period. For further information 
about the calculation methods and uses of the Fund's investment results, see 
the Statement of Additional Information.
