Prospectus 
Class A and B Shares 
April 28, 1995 
(revised June 19, 1995) 
    

   The investment objective of Pioneer Tax-Free Income Fund (the "Fund") is to 
seek as high a level of income exempt from regular federal income tax as 
possible, consistent with preservation of capital. The Fund invests primarily 
in a diversified portfolio of tax-exempt bonds. 

   Fund returns and share prices fluctuate and the value of your account upon 
redemption may be more or less than your purchase price. Shares in the Fund are 
not deposits or obligations of, or guaranteed or endorsed by, any bank or other 
depository institution, and the shares are not federally insured by the Federal 
Deposit Insurance Corporation, the Federal Reserve Board or any other 
government agency. 

   This Prospectus (Part A of the Registration Statement) provides the
information about the Fund that you should consider before investing. Please
read and retain it for future reference. More information about the Fund is
included in the Statement of Additional Information (Part B of the Registration
Statement), dated April 28, 1995, which is incorporated by reference into this
Prospectus. A copy of the Statement of Additional Information may be obtained
free of charge by calling Shareholder Services at 1-800-225-6292 or by written
request to the Fund at 60 State Street, Boston, Massachusetts 02109. Other
information about the Fund has been filed with the Securities and Exchange
Commission (the "SEC") and is available upon request and without charge.

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 estimated annual operating expenses based on actual 
expenses of the Class A shares for the fiscal year ended December 31, 1994.

  + Class B shares are a new class of shares first offered on April 28, 1995. 

(1) Purchases of $1,000,000 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 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. 

(3) For Class B shares, operating expenses are based on estimated expenses that 
    would have been incurred during the previous fiscal year had Class B shares 
    been outstanding. 

 Example: 

   You would pay the following dollar amounts on a $1,000 investment in the 
Fund, assuming 5% annual return and redemption at the end of each of the time 
periods: 

<TABLE>

Class A Shares                  $54         $73          $ 93         $152* 
Class B Shares 
  --Assuming complete 
   redemption at end  of 
  period                        $57         $82          $110         $177* 
- --Assuming no redemption        $17         $52          $ 90         $177* 
</TABLE>

*Class B shares convert to Class A shares eight years after purchase; 
 therefore, Class A expenses are used after year eight. 

   The example above assumes the 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 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, including information regarding the basis upon which 
management fees and 12b-1 fees are paid, 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 imposition 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 Rules of 
Fair Practice 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 seek as high a level of income 
exempt from regular federal income tax as possible, consistent with 
preservation of capital. To achieve this objective, the Fund invests in a 
diversified portfolio of obligations issued by or on behalf of states, counties 
and municipalities of the United States and the authorities and political 
subdivisions thereof (herein called "Tax-Exempt Bonds"), the interest on which 
is excluded from gross income for federal income tax purposes, in the opinion 
of counsel to the issuer of the bond. The Fund's portfolio will primarily 
consist of Tax-Exempt Bonds rated at the time of purchase within the three 
highest grades assigned by Moody's Investors Services, Inc. ("Moody's") (Aaa, 
Aa or A) or Standard & Poor's Ratings Group ("S&P") (AAA, AA or A). Securities 
in which the Fund invests may not yield as high a level of current income on a 
pre-tax basis as securities subject to regular federal income tax or securities 
of lower quality which generally are less liquid and have greater market risk 
and price fluctuation. 

   The Fund may also invest in temporary investments consisting of: (1) notes 
issued by or on behalf of municipal issuers backed by the U.S. government; (2) 
notes of issuers having, at the time of purchase, an issue of outstanding Tax- 
Exempt Bonds rated within the three highest grades of the rating services as 
described above; (3) securities of other investment companies*; (4) obligations 
of the U.S. government, its agencies or instrumentalities*; (5) commercial 
paper rated in the highest grade by either of such rating services (Prime-I or 
A-I, respectively)*; (6) bank instruments (including certificates of deposit, 
time deposits and bankers' acceptances) of domestic or foreign banks with 
assets of $1 billion or more*; and (7) repurchase agreements on such 
securities* with banks or broker-dealers. During periods of normal market 
conditions, the Fund will have at least 80% of its net assets invested in 
Tax-Exempt Bonds, with up to 20% of the Fund's assets in temporary investments 
or cash. When the investment adviser believes that market conditions dictate a 
defensive posture, a greater percentage of the Fund's assets may be invested in 
temporary investments. The asterisk (*) indicates that the income from these 
securities is or may be subject to federal income tax. 

   The Fund may invest more than 25% of its total assets in securities, 
payments on which are derived from funds provided by companies in the gas, 
electric, telephone, sewer and water, public and private utility segments of 
the municipal bond market. The Fund will not purchase securities if, as a 
result of such transaction, more than 25% of its total assets would be invested 
in any one industry. For purposes of this limitation, Tax-Exempt Bonds, except 
those issued for the benefit of non-governmental users, are not considered to 
be part of an industry. The Fund may invest 25% or more of its total assets in 
Tax-Exempt Bonds of issuers in any one state and may invest 25% or more of its 
total assets in industrial development bonds. 

Investment Company Securities 

   The Fund may invest up to 10% of the value of its total assets in securities 
of other investment companies, with up to 5% of the value of the Fund's total 
assets invested in securities of any one investment company, but may not own 
more than 3% of the outstanding voting securities of any one investment 
company. Because investments in other investment companies involve expenses 
being incurred by those companies as well as comparable expenses being incurred 
by the Fund, investments in other investment companies will generally be used 
only for short-term investing and only when the Fund reasonably anticipates 
that the net return to the Fund's shareholders will be advantageous, as 
compared to available alternatives, while maintaining the appropriate level of 
liquidity. It is expected that most of such investing will be in no-load, 
tax-free money market funds that invest, as far as practicable, in the same 
quality of investments as the Fund may invest in directly. 

Options 

   The Fund may write (sell) "covered" put and call options on fixed-income 
securities. Call options are "covered" by the Fund when it owns the underlying 
securities, or owns securities convertible into or carrying rights to acquire 
such securities without payment of additional consideration, which the option 
holder has the right to purchase, and put options are "covered" by the Fund 
when it has established a segregated account of cash or liquid, high-grade debt 
obligations sufficient to satisfy the Fund's obligation to purchase the 
underlying securities. The Fund receives a premium from writing a put or call 
option, which increases the Fund's gross income in the event the option expires 
unexercised or is closed out at a profit. By writing a call option, the Fund 
limits its opportunity to profit from any increase in the market value of the 
underlying security above the exercise price of the option. By writing a put 
option, the Fund assumes the risk that it may be required to purchase the 
underlying security for an exercise price higher than its then current market 
value, resulting in a capital loss unless the security subsequently appreciates 
in value. 

   The Fund intends to write and purchase options on securities primarily for 
hedging purposes and also in an effort to increase current income. 
Distributions to shareholders of any gains from options transaction will be 
taxable. Options on securities that are written or purchased by the Fund will 
be entered into on U.S. exchanges and in the over-the-counter market. 
Over-the-counter transactions involve certain risks which may not be present in 
a transaction on an exchange. The staff of the SEC has taken the position that 
over-the-counter options and assets used to cover over-the-counter options are 
illiquid and, therefore, together with other illiquid securities, cannot exceed 
15% of the Fund's net assets. 

   The writing and purchase of options is a highly specialized activity which 
involves investment techniques and risks different from those associated with 
ordinary portfolio securities transactions. The successful use of options for 
hedging purposes depends in part on the investment adviser's ability to predict 
future price fluctuations and the degree of correlation between the options and 
securities markets. If the investment adviser is incorrect in its determination 
of the correlation between the securities or indices on which the options are 
written and purchased and the securities in the Fund's investment portfolio, 
the investment performance of the Fund will be less favorable than it would 
have been in the 

                                        4 
<PAGE> 
absence of such option transactions. The Fund pays brokerage commissions or 
spreads in connection with its options transactions. The writing of options 
could significantly increase the Fund's portfolio turnover rate. 

Futures Contracts and Options on Futures Contracts 

   To hedge against changes in interest rates and securities prices or for 
non-hedging purposes, the Fund may purchase and sell futures contracts on fixed 
income securities or indices composed of such securities, including municipal 
bonds and U.S. Treasury securities, and purchase and write call and put options 
on such futures contracts. The Fund may also enter into closing purchase and 
sale transactions with respect to any of such contracts and options. The 
futures contracts may be based on various securities (such as U.S. government 
securities), securities indices and other financial instruments and indices. 
The Fund will engage in futures and related options transactions only for bona 
fide hedging purposes as defined in regulations of the Commodities Futures 
Trading Commission or for non-hedging, speculative purposes to the extent 
permitted by such regulations. 

   The Fund may not purchase or sell futures contracts or purchase or sell 
related options for non-hedging purposes, except for closing purchase or sale 
transactions, if immediately thereafter the sum of the amount of initial 
margins and premiums on the Fund's outstanding non-hedging positions in futures 
and related options would exceed 5% of the market value of the Fund's net 
assets. Transactions in futures contracts and options on futures involve 
brokerage costs, require margin deposits and, in the case of contracts and 
options obligating it to purchase securities, require the Fund to segregate 
assets with a value equal to the amount of the Fund's obligations. The Fund 
will not enter into option transactions or futures contracts or options thereon 
if immediately thereafter more than 35% of the market value of the Fund's net 
assets would be represented by such instruments. 

   While transactions in futures contracts and options on futures may reduce 
certain risks, such transactions themselves entail certain other risks. Thus, 
while the Fund may benefit from the use of futures and options on futures, 
unanticipated changes in interest rates or securities prices may result in a 
poorer overall performance for the Fund than if it had not entered into any 
futures contracts or options transactions. The loss incurred by the Fund in 
writing options on futures is potentially unlimited and may exceed the amount 
of the premium received. In the event of an imperfect correlation between a 
futures position and a portfolio position which is intended to be protected, 
the desired protection may not be obtained and the Fund may be exposed to risk 
of loss. Perfect correlation between the Fund's futures positions and portfolio 
positions may be impossible to achieve. The Fund's transactions in options and 
futures contracts may be limited by the requirements of the Internal Revenue 
Code of 1986, as amended (the "Code"), for qualification as a regulated 
investment company, and distributions to shareholders of any gains from such 
transactions will be taxable. 

Other Information 

   The yields and market values of municipal securities are determined 
primarily by the general level of interest rates, the creditworthiness of the 
issuers of municipal securities and economic and political conditions affecting 
such issuers. Due to their tax exempt status, the yields and market prices of 
municipal securities may be adversely affected by changes in tax rates and 
policies, which may have less effect on the market for taxable fixed income 
securities. Moreover, certain types of municipal securities, such as housing 
revenue bonds, involve prepayment risks which could affect the yield on such 
securities. 

   Investments in municipal securities are subject to the risk that the issuer 
could default on its obligations. Such a default could result from the 
inadequacy of the sources or revenues from which interest and principal 
payments are to be made or the assets collateralizing such obligations. Revenue 
bonds, including private activity bonds, are backed only by specific assets or 
revenue sources and not by the full faith and credit of the governmental 
issuer. 

   The Fund will limit portfolio turnover to the extent practicable and 
consistent with its investment objective and policies. While it does not intend 
to engage in short-term trading, the Fund is not precluded from taking 
advantage of short-term trends and yield disparities that might occur from time 
to time. A higher portfolio turnover rate (over 100%) may result in 
correspondingly higher transaction costs and may increase the realization of 
net short-term capital gains, distributions of which are taxable to 
shareholders as ordinary income. 

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, however, 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 mar- 

                                        5 
<PAGE> 
ket 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, the investment 
adviser, 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. Distributions to shareholders of income from repurchase 
agreements are taxable. 

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 
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 of and general 
background information regarding each Trustee and executive officer of the 
Fund. 

   Each domestic fixed income portfolio managed by PMC, including the Fund, is 
overseen by the Domestic Fixed Income Portfolio Management Committee, which 
consists of PMC's most senior domestic fixed income 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. 
Fixed income investments at PMC, including those made on behalf of the Funds, 
are under the general supervision of Mr. Sherman Russ, a Senior Vice President 
of PMC. Mr. Russ joined PMC in 1983. Mr. Mark Winter, Vice President of the 
Fund and PMC, is primarily responsible for the day-to-day management of the 
Fund. Mr. Winter assumed responsibility for the Fund in 1986 when it was 
managed by FMC. Mr. Winter joined PMC in 1993. In certain instances where the 
individual named above is unavailable, primary responsibility for the 
day-to-day management of the Fund may be assumed temporarily by Ms. Kathleen D. 
McClaskey who joined PMC in 1986 and is a Vice President of PMC. 

   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 Delaware corporation. PGI's subsidiary, Pioneer Funds Distributor, Inc. 
("PFD"), is the principal underwriter of shares 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. PMC's and PFD's executive offices are located at 60 
State Street, Boston, Massachusetts 02109. 

   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 

                                        6 
<PAGE> 
Statements of Additional Information for filing with the SEC; (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: 
<TABLE>
<CAPTION>
                        Net Assets                              Annual Fee 
<S>                                                                 <C>
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% 
</TABLE>

   PMC has agreed that until December 1, 1995, its fee shall not exceed the fee 
that would have been payable under the prior management contract with FMC. See 
the Statement of Additional Information for a discussion of the fee payable 
under the prior management agreement. 

   For the fiscal year ended December 31, 1994, the Fund paid a management fee 
of $2,266,099 to PMC. 

   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 15% of the outstanding capital stock of PGI as of March 31, 1995. 

V. FUND SHARE ALTERNATIVES 

   The Fund continuously offers two Classes of shares designated as Class A and 
Class B 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 contingent deferred sales 
charge ("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. 

   Purchasing Class A or Class B 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, 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. 

   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 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. 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 at the public offering price from any securities 
broker-dealer which has a sales agree-

                                        7 
<PAGE> 
ment with PFD. If you do not have a securities broker-dealer, please call 
1-800-225-6292 for assistance. 

   The minimum initial investment is $1,000 for Class A and Class B 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 shares except that the subsequent minimum investment amount 
for Class B share accounts may be as little as $50 if an automatic investment 
plan is established (see "Automatic Investment Plans"). 

Class A Shares 

   You may buy Class A shares at the public offering price, that is, at the net 
asset value per share next computed after receipt of a purchase order, plus a 
sales charge as follows: 
<TABLE>
<CAPTION>
                                      Sales Charge as a % of      Dealer

</TABLE>

   No sales charge is payable at the time of purchase on investments of 
$1,000,000 or more or for 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 $1 million invested; 
0.50% on the next $4 million; and 0.10% on the excess over $5 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 pays 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. 

   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 (except direct 
purchases of Pioneer Money Market Trust's Class A shares) 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. 

   
   Telephone Purchases. Your account is automatically authorized to have the 
telephone purchase privilege unless you indicated 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 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 IRA accounts 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 acceptance 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. 
    

   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 a Fund may be sold at net asset 
value per share without a sales charge to Optional Retirement 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. Information about 
such arrangements is available from PFD. 

                                        8 
<PAGE> 
   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 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 funds. Further details may be obtained from 
PFD. 

Class B Shares 

   You may buy Class B shares at net asset value without the imposition of an 
initial sales charge; however, Class B shares redeemed within six years of 
purchase will be subject to a 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.

Seventh and thereafter                          none 
</TABLE>

   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 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 at the time any particular conversion would normally occur. The 
conversion of Class B shares to Class A shares will not occur if such ruling or 
opinion will be available is not available and, therefore, Class B shares would 
continue to be subject to higher expenses than Class A shares for an 
indeterminate period. 

   Waiver or Reduction of Contingent Deferred Sales Charge. The CDSC on Class B 
shares and on any Class A shares subject to a CDSC 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 

                                        9 
<PAGE> 
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 and on any Class A shares subject to a CDSC 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 Individual Retirement 
Account ("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 
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 B 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 the Fund's right to liquidate or involuntarily redeem 
shares in a shareholder's account. 

   Broker-Dealers. An order for either 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. 

   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 
            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 and accepted less any applicable CDSC. Sale proceeds generally will 
be sent to you in cash, normally within seven days after your order is 
accepted. 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 situations 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, Pioneer will send the proceeds of the sale 
to the address of record. Fiduciaries or 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 
and accepted 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 

                                       10 
<PAGE> 
owner(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 indicated otherwise on your Account 
Application or by writing to the Fund. You may redeem up to $50,000 of your 
shares by telephone or fax and receive the proceeds by check or bank wire or 
electronic funds transfer. The redemption proceeds must be made payable exactly 
as the account is registered. To receive the proceeds by check: 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 previously designated bank address of record 
which must have been properly pre-designated 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. The 
telephone redemption option is not available to retirement plan accounts. 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 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 $1,000,000 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 fund will continue to be subject to the CDSC until the 
original 12-month period expires. However, no CDSC is payable with respect to 
purchases of Class A shares 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 
Pioneer mutual 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 si gned 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 indicated otherwise on your Account 
Application or by writing to the Fund. Proper account identification will be 
required for each telephone exchange. Telephone exchanges may not exceed 
$500,000 per account per day. Each voice-requested or FactFone|PS telephone 
exchange request 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 
account for shares of the same Class in another Pioneer 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 18th day of the month. 

   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 account opened 
through an exchange must have a registration identical to that on the original 
account. 

   Class A or Class B 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 

                                       11 
<PAGE> 
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 Class B 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. To prevent abuse of the exchange privilege to the 
detriment of other Fund shareholders, the Fund and PFD reserve the right to 
limit the number and/or frequency of exchanges and/or to charge a fee for 
exchanges. The exchange privilege may be changed or discontinued and may be 
subject to additional limitations, including certain restriction on purchases 
by market timer accounts. 
    

X. DISTRIBUTION PLANS 

   The Fund has adopted a Plan of Distribution for both Class A shares ("Class 
A Plan") and Class B shares ("Class B 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 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 shareholders of the Fund. 

   The Class B Plan provides 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 
Class B 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 Class B 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 
shares. PFD also receives the proceeds of any CDSC imposed on the redemption of 
Class B 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. 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 for which there is no dealer of record or for which 
qualification standards have not been met as partial consideration for personal 
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 the Code so that it will 
not pay federal income taxes on income and capital gains distributed to 
shareholders at least annually. The Code permits tax-exempt interest received 
by the Fund to flow through as tax-exempt "exempt-interest dividends" to the 
Fund's shareholders, provided that the Fund qualifies as a regulated investment 
company and at least 50% of the value of the total assets of the Fund at the 
close of each quarter of its taxable year consists of tax-exempt obligations. 
However, distributions derived from interest on certain "private activity 
bonds" will be subject to the federal alternative minimum tax for individuals, 
estates or trusts that are subject to such tax, and all tax exempt 
distributions may result in or increase a corporate shareholder's liability for 
the federal corporate alternative minimum tax. 

                                       12 
<PAGE> 
   Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of the Fund will not be deductible for federal income tax purposes to 
the extent it is deemed related to exempt-interest dividends. The Fund may not 
be an appropriate investment for persons who are "substantial users" of 
facilities financed by industrial revenue or private activity bonds or persons 
related to substantial users. Shareholders receiving social security or certain 
railroad retirement benefits may be subject to federal income tax on a portion 
of such benefits as a result of receiving investment income, including 
exempt-interest dividends and other distributions paid by the Fund. 

   Under the Code, the Fund will be subject to a nondeductible 4% federal 
excise tax on a portion of its undistributed taxable 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. 

   Each business day the Fund declares a dividend consisting of substantially 
all of the Fund's net investment income. Shareholders begin earning dividends 
on the first business day following receipt of payment for purchased shares. 
Shares continue to earn dividends up to and including the date of redemption. 
Dividends are normally paid on the last business day of the month or shortly 
thereafter. The Fund's net investment income consists of the interest income it 
earns, less expenses. In computing interest income, the Fund amortizes premium 
or accrues discount on long-term debt securities only to the extent required 
for federal income tax purposes. The Fund will make distributions from net long 
term capital gains, if any, in December. Net short-term capital gains 
distributions, if any, may be paid with such dividends, and other distributions 
from income and/or capital gains may also be made at such times as may be 
necessary to avoid federal income or excise tax. 

   Unless shareholders specify otherwise, all distributions from the Fund will 
be automatically reinvested in additional full and fractional shares of the 
Fund. For further information on the distribution options available to 
shareholders, see "Distribution Options" and "Directed Dividends" below. 

   The Fund's dividends from its taxable net investment income, including 
taxable interest income, taxable original issue discount, market discount 
income, income from securities lending and any net short-term capital gains 
realized by the Fund are taxable to shareholders as ordinary income under the 
Code. Dividends from the Fund's net long-term capital gains are taxable to 
shareholders as long-term capital gains under the Code, regardless of a 
shareholder's holding period for his Fund shares. For federal income tax 
purposes, dividends are taxable as described above whether a shareholder takes 
them in cash or reinvests in additional shares of the Fund. 

   The federal income tax status of all distributions will be reported to 
shareholders annually, and taxable shareholders are required to report all 
distributions, including tax-exempt distributions, on their federal income tax 
returns. 

   The Fund's taxable dividends and other taxable distributions, and the 
proceeds of redemptions, exchanges or repurchases of the Fund's shares paid to 
individuals and other non-exempt payees may be subject to a 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 that the shareholder is not subject to such backup 
withholding or if the Fund receives notice from the IRS or a broker that backup 
withholding applies. 

   
   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. A state income (and possibly local income and/or intangible 
property) tax exemption is generally available to the extent the Fund's 
distributions are derived from interest on (or, in the case of intangibles 
taxes, the value of its assets is attributable to) certain U.S. Government 
obligations and/or tax-exempt municipal obligations issued by or on behalf of 
the particular state or a political subdivision thereof, provided in some 
states that certain thresholds for holdings of such obligations an/or reporting 
requirements are satisfied. Non-U.S. shareholders and tax-exempt shareholders 
are subject to different tax treatment that is not described above. You should 
consult your own tax adviser regarding this possibility and other tax 
consequences under 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 
Combined Account Statement, mailed quarterly, is available to shareholders who 
have more than one Pioneer 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 investment or 
redemption of shares by mail, automatic reinvestment of dividends and capital 
gains distributions, withdrawal plans, Letters of Intention, Rights of 
Accumulation, telephone exchanges and redemptions and newsletters. 

                                       13

Additional Investments 

   You may add to your account by sending a check (minimum of $50 for Class A 
shares and $500 for Class B 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 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 Investomatic Plan provides for a monthly or 
quarterly investment by means of a pre-authorized 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 fund 
account invested in a second Pioneer 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 indicated otherwise on your Account Application or by 
writing to the Fund. You may purchase, sell or exchange Fund shares by 
telephone. For personal assistance, call 1-800-225-6292 between 8:00 a.m. and 
8:00 p.m. Eastern time on weekdays. Computer-assisted transactions are 
available to shareholders who have pre-recorded certain bank information (see 
FactFone|PS). You are strongly urged to consult with your financial 
representative prior to requesting any telephone transaction. See "Share Price" 
for more information. To confirm that each transaction instruction received by 
telephone is genuine, the Fund 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 or 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 is an automated inquiry and telephone transaction system available 
to Pioneer shareholders by dialing 1-800-225-4321. FactFone allows you to 
obtain current information on your Pioneer accounts and to inquire about the 
prices and yields of all publicly available Pioneer mutual funds. In addition, 
you may use FactFone to make computer-assisted telephone purchases, exchanges 
and redemptions from your Pioneer accounts if you have activated your personal 
identification number ("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. 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. 
    

Telecommunications Device for the Deaf (TDD) 

   If you have a hearing disability and your own TDD keyboard equipment, you 
can call our TDD number toll-free at 

                                       14 
<PAGE> 
1-800-225-1997, 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 shares accounts are limited to 10% of the 
value of the account at the time the plan 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. 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 
Systematic Withdrawal Plan 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 reinvestment occurs. 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 management investment company (commonly referred to as 
a mutual fund), was established as a Nebraska corporation on January 19, 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 two classes of shares, designated as Class A and Class B. 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 and Class B 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 certificates. 

XIV. INVESTMENT RESULTS 

   The Fund may from time to time include yield information for each Class of 
Fund shares in advertisements or in information furnished generally to existing 
or proposed shareholders. Whenever yield information is provided, it includes a 
standardized yield calculation computed by dividing the Fund's net investment 
income per share for each class of Fund shares during a base period of 30 days, 
or one month, by the maximum offering price per share for each class of Fund 
shares on the last day of such base period. (The Fund's net investment income 
per share for each Class is determined by dividing the Fund's net investment 
income for each 

                                       15 
<PAGE> 
Class during the base period by the Class's average number of shares entitled 
to receive dividends during the base period). The Class's 30-day yield is then 
"annualized" by a computation that assumes that the Class's net investment 
income is earned and reinvested for a six-month period at the same rate as 
during the 30-day base period and that the resulting six-month income will be 
generated over an additional six months. 

   The Fund may also from time to time advertise its taxable equivalent yield 
for each Class of Fund Shares. The Class's taxable equivalent yield is 
determined by dividing that portion of the Class's yield (calculated as 
described above) that is tax exempt by one minus the stated federal income tax 
rate and adding the product to that portion, if any, of the Class's yield that 
is not tax exempt. For a table of sample taxable equivalent yields, please see 
the Appendix. 

   The average annual total return (for a designated period of time) on an 
investment in the Fund may also 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 formula. 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 4.50%; for Class B shares the 
calculation reflects the deduction of any applicable contingent deferred sales 
charge. 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. Yield and return quotations should also 
be considered in relation to the risks associated with the Fund's investment 
objective and policies. Yields may be affected by sinking fund call provisions 
and optional redemption features of portfolio securities which may have the 
effect of reducing the stated average maturity of the Fund's portfolio. 

   Other investments or savings vehicles and/or unmanaged market indexes, 
indicators of economic activity or averages of mutual funds 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 yield and investment results will be calculated separately for 
each class of Fund shares and will vary from time to time depending on market 
conditions, the composition of the Fund's portfolio, the operating expenses of 
the Fund and the expenses attributed to a particular 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.

XV. APPENDIX: Taxable Equivalent Yields* 

   The table below shows the approximate taxable yields which are equivalent to 
hypothetical tax-exempt yields from 5% to 9% under Federal income tax laws 
applicable to individuals during 1995.

</TABLE>

 *Net amount subject to Federal income tax after deductions and exemptions. 
  Table does not reflect the effect of Deduction Limitation and Exemption 
  Phaseout described below** or of the alternative minimum tax, if any. Table 
  assumes person filing Single Return is not a married individual filing a 
  separate return, a surviving spouse, or a head of household. 

**Deduction Limitation: Each $100 of adjusted gross income ("AGI") in excess of 
  $114,700 ($57,350 for marrieds filing separately) causes the loss of $3 of 
  itemized deductions. This limitation affects all itemized deductions other 
  than medical expenses, investment interest, and casualty, theft and wagering 
  losses. However, not more than 80% of a taxpayer's itemized deductions can be 
  eliminated. The threshold amounts will be adjusted for inflation from year to 
  year. 
  Exemption Phaseout: Each $2,500 or fraction thereof of AGI in excess of 
  $172,050 for joint filers ($114,700 for single taxpayers) causes taxpayers to 
  lose 2% of their personal exemptions. The threshold amounts will be adjusted 
  for inflation from year to year. 

   The following formula can be used to calculate a taxable yield 
which is equivalent to the corresponding tax-free yield: 

                   Tax Free Yield  
                  ------------------  = Taxable Equivalent Yield 
                  1-Your Tax Bracket 

   For example, if you are in the 28% tax bracket and earn a tax-free 
yield of 7%, the taxable equivalent yield would be 9.72%. 

                7%       .07
             -------  =  ---  = 9.72% 
             1 - 28%     .72 

   There can be no assurance that the Fund will achieve any specific tax-exempt 
yield. While it is expected that a substantial portion of the interest income 
distributed to investors in the Fund will be exempt from regular federal income 
taxes, portions of such distributions may be subject to regular federal income 
tax or federal alternative minimum tax. In addition, all or a substantial 
portion of such distributions may be subject to state and local taxes. 
Subsequent tax law changes could result in prospective or retroactive changes 
in the tax brackets, tax rates and tax equivalent yields set forth above.
