Pioneer 
Europe Fund 
Class A and Class B Shares 
Prospectus 
February 28, 1995 

PIONEER EUROPE FUND (the "Fund") seeks long-term growth of capital. The Fund 
pursues this objective by investing in a diversified portfolio consisting 
primarily of securities of European companies and in Depositary Receipts for 
such securities. Any current income generated from these securities is 
incidental to the investment objective of the Fund. There is, of course, no 
assurance that the Fund will achieve its investment objective. 

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. Investments in securities issued by foreign companies or 
governments entail risks in addition to those customarily associated with 
investing in U.S. securities. The Fund is intended for investors who can 
accept the risks associated with its investments and may not be suitable for 
all investors. See "Investment Objective and Policies" for a discussion of 
these risks. 

This Prospectus (Part A of the Registration Statement) provides information 
about the Fund that you should know before investing. Please read and retain 
it for your future reference. More information about the Fund is included in 
Part B, the Statement of Additional Information, also dated February 28, 
1995, which is incorporated into this Prospectus by reference. 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

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 upon 
actual expenses for the fiscal year ended October 31, 1994. 

                                               Class A        Class B

  Dividends                                     None           None 
Maximum Deferred Sales Charge                   None(1)        4.00%

Exchange Fee                                    None           None

12b-1 Fees                                      0.21%          1.00% 
Other Expenses (including accounting and 
  transfer agent fees, custodian fees and 
  printing expenses)                            1.27%          0.95% 
Gross Operating Expenses                        2.48%          2.95% 
Expense limitation by Manager(4)               (0.62)%        (0.48)% 
Net Operating Expenses (After Expense 
  Limitation)                                   1.86%          2.47% 


(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. 

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

(3) For Class B shares, percentages are based on estimated expenses that 
would have been incurred during the previous fiscal year had Class B shares 
been outstanding for the entire period. Class B shares, were first offered 
April 4, 1994. 

(4) Effective April 30, 1994, Pioneering Management Corporation (the 
"Manager") agreed not to impose a portion of its management fee to the extent 
necessary to limit Class A expenses to 1.75% of the average daily net assets 
attributable to Class A shares. The management fee attributable to Class B 
shares will be imposed only to the extent it is imposed for Class A shares. 
This agreement is voluntary and temporary and may be revised or terminated at 
any time. 

(5) Effective April 30, 1994, the management fee was reduced from 1.10% to 
1.00%. 

Example: 

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

                               1 Year      3 Years      5 Years     10 Years 

Class A Shares                   $75         $113         $152       $263 
Class B Shares 
- --Assuming complete 
  redemption at end of 
  period                         $65         $107         $152       $265* 
- --Assuming no redemption         $25         $ 77         $132       $265* 


*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 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 may 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 "Distribution Plans" in the Statement of 
Additional Information. The Fund's payment of a 12b-1 fee may result in 
long-term shareholders indirectly paying more than the economic equivalent of 
the maximum initial sales charge permitted under the National Association of 
Securities Dealers, Inc. Rules of Fair Practice. 

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 other publicly available mutual funds in the Pioneer 
complex. See "How to Exchange Fund Shares."

III. INVESTMENT OBJECTIVE AND POLICIES 

The Fund's investment objective is long-term growth of capital. The Fund 
pursues this objective by investing in a diversified portfolio consisting 
primarily of securities of companies (a) that are organized under the laws of 
a European country and have a principal office in a European country or (b) 
that derive 50% or more of their total revenues from business in Europe or 
(c) the equity securities of which are traded principally on a stock exchange 
in Europe; and in Depositary Receipts for such securities (collectively, 
"European Securities"). 

Under normal circumstances at least 80% of the assets of the Fund are 
invested in European Securities consisting of common stock and in securities 
with common stock characteristics, such as preferred stock, warrants and debt 
securities convertible into common stock. The Fund will not invest more than 
5% of its total assets in convertible debt securities rated by a national 
ratings agency below investment grade, i.e., BBB or better by Moody's 
Investors Service ("Moody's") or Baa by Standard & Poor's Ratings Group 
("Standard & Poor's"). Such securities may have speculative characteristics 
and changes in economic conditions or other circumstances may lead to a 
lesser capacity to make principal and interest payments than is the case with 
higher rated securities. In the event that the rating on a convertible debt 
security is downgraded below investment grade, the Manager will dispose of 
the security in a timely manner. The Fund may invest the balance of its 
assets in Temporary Investments (as defined below). 

The Fund may invest in the securities of companies domiciled in any European 
country, including but not limited to Austria, Belgium, Finland, France, 
Germany, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, 
Switzerland, the United Kingdom and the countries of Eastern Europe in the 
event that markets develop for those securities. 

No investment is made if as a result 25% or more of the Fund's total assets 
would be invested in any one European country. 

The Fund's investment objective and certain investment restrictions 
designated as fundamental set forth in the Statement of Additional 
Information may not be changed without shareholder approval. 

Forward Foreign Currency Contracts 

The Fund has the ability to hold a portion of its assets in foreign 
currencies and to enter into forward foreign currency contracts to facilitate 
settlement of foreign securities transactions or to protect against changes 
in foreign currency exchange rates. A forward foreign currency contract 
involves an obligation to purchase or sell a specific currency on a future 
date, at a price set at the time of the contract. The Fund might sell a 
foreign currency on either a spot or forward basis to hedge against an 
anticipated decline in the dollar value of securities in its portfolio or 
securities it intends or has contracted to sell or to preserve the United 
States ("U.S.") dollar value of dividends, interest or other amounts it 
expects to receive. Although this strategy could minimize the risk of loss 
due to a decline in the value of the hedged foreign currency, it could also 
limit any potential gain which might result from an increase in the value of 
the currency. Alternatively, the Fund might purchase a foreign currency or 
enter into a forward purchase contract for the currency to preserve the U.S. 
dollar price of securities it is authorized to purchase or has contracted to 
purchase. 

The Fund may also engage in cross-hedging by using forward contracts in one 
currency to hedge against fluctuations in the value of securities denominated 
in a different currency, if the Fund's Manager determines that there is a 
pattern of correlation between the two currencies. Cross-hedging may also 
include entering into a forward transaction involving two foreign currencies, 
using one foreign currency as a proxy for the U.S. dollar to hedge against 
variations in the other foreign currency, if the Manager determines that 
there is a pattern of correlation between the proxy currency and the U.S. 
dollar. 

If the Fund enters into a forward contract to buy foreign currency for any 
purpose, the Fund will be required to place cash or liquid, high grade liquid 
debt securities in a segregated account with the Fund's Custodian in an 
amount equal to the value of the Fund's total assets committed to the 
consummation of the forward contract. The Fund may enter into forward 
currency contracts having an intrinsic value of up to 30% of its net assets. 

Options 

To realize greater income than would be realized on portfolio transactions 
alone, the Fund may write (sell) covered 

                                      4 
<PAGE>
 
call and put options on any securities in which it may invest or on any 
securities index based on securities in which the Fund may invest. The Fund 
may also write (as closing transactions) and purchase put and call options on 
such securities and indices. 

The Fund may purchase put and call options on securities indices to manage 
cash flow and to attempt to remain fully invested in the stock market, 
instead of or in addition to buying and selling stocks. The Fund may also 
purchase these options in order to hedge against risks of market-wide price 
fluctuations. Options on securities indices are similar to options on 
securities except that the delivery requirements are different. Unlike a 
securities option, which gives the holder the right to purchase or sell a 
specified security at a specified price, an option on a securities index 
gives the holder the right to receive a cash "exercise settlement amount" 
equal to (i) the difference between the exercise price of the option and the 
value of the underlying securities index on the exercise date, (ii) 
multiplied by a fixed "index multiplier." In exchange for undertaking the 
obligation to make such a cash payment, the writer of the securities index 
option receives a premium. 

Gains or losses on the Fund's transactions in securities index options depend 
on price movements in the securities market generally (or, for narrow market 
indices, in a particular industry or segment of the market) rather than the 
price movement of individual securities held by the Fund. The effectiveness 
of hedging through the purchase of stock index options will depend upon the 
extent to which price movements in the portion of the securities portfolio 
being hedged correlate with the price movements in the selected stock index. 
Perfect correlation may not be possible because the securities held or to be 
acquired by the Fund may not exactly match the composition of the stock index 
on which options are written. In the event of market changes, the Fund's 
position in stock index options may not be easily closed out. If the 
forecasts of the Fund's Manager regarding movements in securities prices are 
incorrect, the Fund's investment results may have been better without the 
hedge. The Fund has no present intention of investing more than 5% of the 
Fund's total assets in securities index option transactions. 

The Fund may also purchase and write put and call options on foreign 
currencies for the purpose of protecting against declines in the dollar value 
of foreign portfolio securities and against increases in the U.S. dollar cost 
of foreign securities to be acquired. The Fund may also use options on 
currency to cross-hedge, which involves writing or purchasing options on one 
currency to hedge against changes in exchange rates of a different currency 
with a pattern of correlation. Cross-hedging may also include using a foreign 
currency as a proxy for the U.S. dollar if the Manager determines that there 
is a pattern of correlation between that currency and the U.S. dollar. The 
writing of an option on foreign currency will constitute only a partial 
hedge, up to the amount of the premium received, and the Fund could be 
required to purchase or sell foreign currencies at disadvantageous exchange 
rates, thereby incurring losses. The purchase of an option on a foreign 
currency may constitute an effective hedge against exchange rate 
fluctuations. However, in the event of unanticipated rate movements adverse 
to the Fund's option position, the Fund may forfeit the entire amount of the 
premium plus related transaction costs. Options on foreign currencies to be 
written or purchased by the Fund will be traded on U.S. or foreign exchanges 
or over-the-counter. The Fund may sell an option it has purchased or a 
similar option prior to the expiration of the purchased option in order to 
close out its position in the purchased option. The Fund may also allow 
purchased options to expire unexercised, which would result in the loss of 
the premium paid. Options traded in the over-the-counter market may be 
considered illiquid. There is no assurance that a liquid secondary market 
will exist for any particular option at any particular time, and the Fund may 
therefore be unable to effect closing transactions on, or sell, options it 
has purchased. The Fund may not invest more than 10% of its net assets in 
premiums on purchased options. See "Investment Policies and Restrictions" in 
the Statement of Additional Information. 

The Fund's transactions in forward currency contracts, futures and options as 
described herein may be limited by the requirements for qualification of the 
Fund as a regulated investment company for tax purposes. See "Tax Status" in 
the Statement of Additional Information. 

Investments in Depositary Receipts 

The Fund may hold securities of foreign issuers in the form of American 
Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global 
Depositary Receipts 

                                      5 
<PAGE>
 
("GDRs") and other similar instruments or other securities convertible into 
securities of eligible issuers. Generally, ADRs in registered form are 
designed for use in U.S. securities markets, and EDRs and GDRs and other 
similar global instruments in bearer form are designed for use in non-U.S. 
securities markets. 

ADRs are denominated in U.S. dollars and represent an interest in the right 
to receive securities of foreign issuers deposited in a U.S. bank or 
correspondent bank. ADRs do not eliminate all the risk inherent in investing 
in the securities of non-U.S. issuers. However, by investing in ADRs rather 
than directly in equity securities of non-U.S. issuers, the Fund will avoid 
currency risks during the settlement period for either purchases or sales. 
EDRs and GDRs are not necessarily denominated in the same currency as the 
securities for which they may be exchanged. For purposes of the Fund's 
investment policies, investments in ADRs, GDRs and similar instruments will 
be deemed to be investments in the underlying equity securities of the 
foreign issuers. The Fund may acquire depositary receipts from banks that do 
not have a contractual relationship with the issuer of the security 
underlying the depositary receipt to issue and secure such depositary 
receipt. To the extent the Fund invests in such unsponsored depositary 
receipts there may be an increased possibility that the Fund may not become 
aware of events affecting the underlying security and thus the value of the 
related depositary receipt. In addition, certain benefits (i.e., rights 
offerings) which may be associated with the security underlying the 
depositary receipt may not inure to the benefit of the holder of such 
depositary receipt. 

Futures Contracts 

The Fund may purchase and sell futures contracts on securities indices, 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 
such futures contracts and options. The Fund will engage in futures contracts 
and related options transactions for bona fide hedging purposes as defined in 
regulations of the Commodity Futures Trading Commission or to seek to 
increase total return to the extent permitted by such regulations. 

The Fund may not purchase or sell futures contracts or purchase related 
options to increase total return, except for closing purchase or sale 
transactions, if immediately thereafter the sum of the amount of initial 
margin deposits on the Fund's outstanding futures and the amount of premiums 
paid for outstanding options on futures entered into for the purpose of 
seeking to increase total return, adjusted to reflect annualized profits and 
losses, would exceed 5% of the value of the Fund's net assets. These 
transactions involve brokerage costs, require margin deposits and, in the 
case of contracts and options obligating the Fund to purchase securities or 
currencies, require the Fund to segregate assets to cover such contracts and 
options. The loss incurred by the Fund in writing options on futures is 
potentially unlimited and may exceed the amount of the premium received. The 
Fund may also enter into futures contracts on currencies, securities or 
interest rates and may purchase and sell options on such futures contracts. 

Repurchase Agreements 

The Fund may enter into repurchase agreements, generally not exceeding seven 
days. Such repurchase agreements will be fully collateralized with securities 
whose market value is not less than 100% of the obligation, valued daily. 
Collateral will be held in a segregated, safekeeping account for the benefit 
of the Fund. The Fund may be prevented from realizing the value of the 
collateral by reason of an order of a court with jurisdiction over an 
insolvency proceeding with respect to the other party to the repurchase 
agreement. 

Forward foreign currency contracts, options and futures contracts are 
described in greater detail in the Statement of Additional Information under 
the caption "Investment Policies and Restrictions." 

Temporary Investments are short-term (less than 12 months to maturity) 
obligations, consisting of: (a) obligations issued or guaranteed by the U.S. 
government or the government of a European country or their respective 
agencies or instrumentalities; (b) international organizations designated or 
supported by multiple foreign governmental entities to promote economic 
reconstruction or development; (c) corporate commercial paper and other 
short-term commercial obligations, in each case rated or issued by companies 
with similar securities outstanding that are rated Prime-1 or Aa or better by 
Moody's or A-1 or AA or better by Standard & Poor's; and (d) obligations 
(including certificates of deposit, time deposits, demand 

                                      6 
<PAGE>
 
deposits and bankers' acceptances) of banks (located in the U.S. or in 
European countries) with securities outstanding that are rated Prime-1 or Aa 
or better by Moody's or A-1 or AA or better by Standard & Poor's. 

The Fund may, for temporary defensive purposes, invest up to 100% of its 
assets in Temporary Investments. The Fund may assume a temporary defensive 
posture only when political and economic factors broadly affect one or more 
European equity markets to such an extent that the Manager believes there to 
be extraordinary risks in being substantially fully invested. 

Securities in the Fund's portfolio will be sold whenever 
the Manager believes that it is necessary without regard to 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 involves greater expenses to the Fund 
and may increase the possibility of shareholders realizing taxable capital 
gains. 

IV. EUROPE 

The Manager believes that a new and favorable environment for investing in 
Europe has been created, and may continue to develop. One of the more 
significant changes is the attempt by the European Community ("EC") to create 
a single market among its member states. It is not possible to quantify the 
economic benefits that might be derived from the attainment of a single 
market among member states of the EC. However, a single market is generally 
expected to reduce costs of doing business, thereby resulting in a reduction 
of prices, and to spur increased competition among businesses in member 
states. There can be no assurance, of course, that the single-market program 
will be achieved or that its anticipated economic benefits will be realized. 

Another development that may provide investment opportunities is the 
development and expansion of free-market economies in Eastern Europe. The 
Fund may invest up to 5% of its assets in securities of companies with 
principal executive offices located in Eastern European countries when those 
securities commence trading on recognized European securities exchanges. It 
is not possible to predict if or when securities of companies located in any 
particular Eastern European country will so commence trading. Even though the 
Fund does not currently invest in such securities, the Manager may invest in 
other European Securities whose issuers can benefit from the expansion of 
free-market economies in Eastern European countries. 

Risk Factors 

Investing in securities of foreign companies and governments involves certain 
considerations and risks which are not typically associated with investing in 
securities of domestic companies and the U.S. government. European companies 
are not subject to uniform accounting, auditing and financial standards and 
requirements comparable to those applicable to U.S. companies. There may also 
be less government supervision and regulation of European securities 
exchanges, brokers and listed companies than exists in the United States. 
Interest and dividends paid by European issuers may be subject to withholding 
and other foreign taxes which will decrease the net return on such 
investments as compared to interest and dividends paid to a fund by domestic 
companies or by the U.S. government. 

In addition, the value of European securities may also be adversely affected 
by fluctuations in the relative rates of exchange between the currencies of 
different nations and by exchange control regulations. There may be less 
publicly available information about European companies compared to reports 
and ratings published about U.S. companies. European securities markets 
generally have substantially less trading volume than domestic markets and 
securities of some European companies are less liquid and more volatile than 
securities of comparable U.S. companies. Brokerage commissions in Europe are 
generally fixed, and other transaction costs on European securities exchanges 
are generally higher than in the United States. To the extent the Fund 
invests in securities of companies located in Eastern European countries, 
there will be both country risks relating to the relative brevity of the 
free-market movements in such countries and company risks relating to the 
brevity of the public-company experience of such companies. 

V. MANAGEMENT OF THE FUND 

The Fund's Board of Trustees has overall responsibility for management and 
supervision of the Fund. There are 

                                      7 
<PAGE>
 
currently eight Trustees, six of whom are not "interested persons" of the 
Fund as defined in the Investment Company Act of 1940, as amended (the "1940 
Act"). The Board meets at least quarterly. By virtue of the functions 
performed by the Manager, the Fund requires no employees other than its 
executive officers, all of whom receive their compensation from the Manager 
or other sources. The Statement of Additional Information contains the names 
and general business and professional background of each Trustee and 
executive officer of the Fund. 

The Manager 

The Fund is managed under a contract with the Manager, which is responsible 
for the overall management of the Fund's assets and business affairs, subject 
only to the authority of the Board of Trustees. The Manager is a wholly-owned 
subsidiary of The Pioneer Group, Inc. ("PGI"), a publicly-traded Delaware 
corporation. Pioneer Funds Distributor, Inc. ("PFD"), a wholly-owned 
subsidiary of PGI, is the principal underwriter of the Fund. John F. Cogan, 
Jr., Chairman and President of the Fund, Chairman and a Director of the 
Manager, Chairman of PFD, and President and a Director of PGI, beneficially 
owned approximately 15% of the outstanding capital stock of PGI as of the 
date of this Prospectus. 

All portfolios managed by the Manager, including the Fund, are overseen by an
Investment Committee (the "Committee"), which consists of the Manager's most
senior investment professionals. The Committee is chaired by Mr. David Tripple,
the Manager's President and Chief Investment Officer and Executive Vice
President of the Fund. Mr. Tripple joined the Manager in 1974 and has had
general responsibility for the Manager's investment operations and specific
portfolio assignments for over five years.

Dr. Norman Kurland, Senior Vice President of the Manager and Vice President 
of the Fund, is generally responsible for the management of the international 
portfolios managed by the Manager. Dr. Kurland joined the Manager in 1990 
after working with a variety of investment and industrial concerns. Patrick 
M. Smith, Vice President of the Manager, is primarily responsible for 
day-to-day management of the Fund. Mr. Smith joined the Manager in 1992 after 
working with several investment advisers. 

In addition to the Fund, the Manager also manages and serves as the 
investment adviser for other mutual funds and is an investment adviser to 
private institutional accounts. The Manager's and PFD's executive offices are 
located at 60 State Street, Boston, Massachusetts 02109. 

The Manager relies primarily on the knowledge, experience and judgment of its 
research staff, but also receives and uses information from a variety of 
outside sources, including brokerage firms, electronic data bases, 
specialized research firms and technical journals. 

Under the terms of its contract with the Fund, the Manager assists in the 
management of the Fund and is authorized in its discretion to buy and sell 
securities for the account of the Fund. The Manager pays all the ordinary 
operating expenses, including executive salaries and the rental of certain 
office space, related to its services for the Fund, with the exception of the 
following which are to be paid by the Fund: (a) charges and expenses for fund 
accounting, pricing and appraisal services and related overhead, including, 
to the extent such services are performed by personnel of the Manager or its 
affiliates, office space and facilities and personnel compensation, training 
and benefits; (b) the charges and expenses of auditors; (c) the charges and 
expenses of any custodian, transfer agent, plan agent, dividend disbursing 
agent and registrar appointed by the Trust with respect to the Fund; (d) 
issue and transfer taxes, chargeable to the Fund in connection with 
securities transactions to which the Fund is a party; (e) 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; (f) fees and expenses involved in registering and 
maintaining registrations of the Fund and/or its shares with the SEC, 
individual states or blue sky securities agencies, territories and foreign 
countries, including the preparation of Prospectuses and Statements of 
Additional Information for filing with the SEC; (g) 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; (h) charges and expenses of legal 
counsel to the Fund and to Trustees; (i) distribution fees paid by the Fund 
in accordance with Rule 12b-1 promulgated by the SEC pursuant to the 1940 
Act; (j) compensation of those Trustees of the Trust who are not affiliated 
with or interested persons of the Manager, the Trust (other than as 
Trustees), PGI or PFD; (k) the cost of preparing 

                                      8 
<PAGE>
 
and printing share certificates; and (l) interest on borrowed money, if any. 
In addition to the expenses described above, the Fund pays all brokers' and 
underwriting commissions chargeable to the Fund in connection with securities 
transactions to which the Fund is a party. 

Effective April 30, 1994, as compensation for its management services and 
certain expenses which the Manager incurs, the Manager is entitled to a 
management fee equal to 1.00% per annum of the Fund's average daily net 
assets up to $300 million, 0.85% of the next $200 million and 0.75% of the 
excess over $500 million. While this fee, which is computed daily and paid 
monthly, is higher than most management fees, the costs of managing an 
international fund, such as the Fund, are significantly greater than the 
costs of managing a domestic fund. These greater costs include staff time and 
expenses required to deal with language, timing and geographic differences 
relating to daily operations of the Fund. 

During the fiscal year ended October 31, 1994, the Fund incurred expenses of 
$1,409,026, including management fees paid or payable to the Manager of 
$592,674. See the Statement of Additional Information for the management fees 
in effect through April 29, 1994. 

Effective April 30, 1994, the Manager has agreed not to impose a portion of 
its management fee to the extent that the Class A expenses of the Fund would 
otherwise exceed 1.75% of the Fund's average daily net assets attributable to 
the Class A shares; the portion of the management fee attributable to Class B 
shares will be waived only to the extent the fee is waived for Class A 
shares. This agreement is voluntary and temporary and may be revised or 
terminated by the Manager at any time. See the Statement of Additional 
Information for the expense limitation in effect through April 29, 1994. 
During the fiscal year ended October 31, 1994, these arrangements resulted in 
a reduction of the Fund's management fee of $348,691. 

The primary objective of the Manager in placing orders for the purchase and 
sale of securities for the Fund's portfolio is to obtain the most favorable 
net results taking into account such factors as price, commission, size of 
order, difficulty of execution and skill required of the broker-dealer. 
Brokerage commissions in European countries are generally fixed and other 
transaction costs on European securities exchanges are generally higher than 
in the U.S. 

In placing orders for the Fund's portfolio securities transactions, the 
Manager strives to obtain the best price and execution for each transaction. 
In circumstances in which 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 any Pioneer mutual fund. See the Statement of Additional 
Information for a further description of brokerage allocation practices. 

VI. 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. 

                                      9 
<PAGE>
 
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 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. 

VII. 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 fair market 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 regular trading on 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 regular trading on 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 regular trading on 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. 

VIII. HOW TO BUY FUND SHARES 

You may buy Fund shares at the public offering price 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 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 (see "Automatic Investment Plans") is established. 

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:

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
Mutual of Omaha Fund Management Company 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 an (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 of 1986, 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. 

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. Information about such arrangements is 
available from PFD. 

Class A shares of the Fund may 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 the Manager 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 
investment advisers adhering to standards established by PFD; (i) other funds 
and accounts for which the Manager 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. Shares may also be sold at net asset 
value in connection with certain reorganization, 

                                      11 
<PAGE>
 
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 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 shares of the Fund; 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. 

Year Since                        CDSC as a Percentage of Dollar 
Purchase                              Amount 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 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, 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. 

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, waiver 

                                      12 
<PAGE>
 
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 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 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 contingent deferred sales charge 
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 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. 

IX. 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: 

* 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 

                                      13 
<PAGE>
 
requested by phone or in writing). Call 1-800-622-0176 for more information. 

* 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 Pioneering Services Corporation 
("PSC"), however, you must use a written request, including a signature 
guarantee, to sell your shares if any of the following situations applies: 

* you wish to sell over $50,000 worth of shares, 

* your account registration or address has changed within the last 30 days, 

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

* the check is not being made out to the account owners, or 

* 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 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 PSC. Proper account identification will be 
required for each telephone redemption. The telephone redemption option is 
not available to retirement plan accounts. A maximum of $50,000 may be 
redeemed by telephone or fax and the proceeds may be received by check or by 
bank wire. 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: the wire must be sent to the bank wire 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. 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. 

Selling Shares Through Your Broker-Dealer. The Fund has 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 

                                      14 
<PAGE>
 
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 of the shares originally held 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. 

X. 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 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 indicated 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. All telephone exchange requests will be 
recorded. 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 fund. Not all Pioneer 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 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 

                                      15 
<PAGE>
 
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 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 in particular circumstances. 

You should consider the differences in objectives and policies of the Pioneer 
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. 

XI. 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.

XII. 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% excise tax on 
a portion of its undistributed income and capital gains if it fails to meet 
certain distribution requirements by the end of the calendar year. The Fund 
intends to make distributions in a timely manner and accordingly does not 
expect to be subject to the excise tax. 

Dividends and other distributions and the proceeds of redemptions or 
repurchases of Fund shares paid to individuals and other non-exempt payees 
will be subject to a 31% federal backup withholding 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 the Fund receives notice from the Internal Revenue 
Service (the "IRS") or a broker that such withholding applies. Please refer 
to the Account Application for additional information. 

The Fund pays dividends from net investment income and distributes its net 
realized short and long-term capital gains, if any, annually, usually in the 
month of December, with additional distributions made only as required to 
avoid federal income or excise tax. Unless shareholders specify otherwise, 
all distributions will be automatically reinvested in additional full and 
fractional shares of the Fund. Dividends from the Fund's net investment 
income, certain net foreign exchange gains and net short-term capital gains 
are taxable as ordinary income, and dividends from the Fund's net long-term 
capital gains are taxable as long-term capital gains. 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. For further information on the distribution options 
available to shareholders, see "Distribution Options" and "Directed 
Dividends" below. 

In any year in which the Fund qualifies, it may make an election that will 
permit certain of its shareholders to take a credit (or, if more 
advantageous, a deduction) for foreign income taxes paid by the Fund. Each 
shareholder would then treat as an additional dividend his or her appropriate 
share of the amount of foreign taxes paid by the Fund. If this election is 
made, the Fund will notify its shareholders annually as to their share of the 
amount of foreign taxes paid and the foreign source income of the Fund. 

The description above relates only to Federal income tax consequences for 
shareholders who are U.S. persons, i.e., U.S. citizens or residents or U.S. 
corporations, partnerships, trust or estates, and who are subject to U.S. 
federal income tax. Shareholders should consult their own tax advisors 
regarding state, local and other applicable tax laws. 

XIII. 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. The 
principal business address of the mutual fund division of the Custodian is 40 
Water Street, Boston, Massachusetts 02109. The Custodian oversees a network 
of subcustodians and depositories in Europe. 

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. The 
Pioneer 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 or telephone, automatic reinvestment of 
dividends and capital gains distributions, withdrawal plans, Letters of 
Intention, Rights of Accumulation, telephone exchanges, and newsletters. 

                                      17

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 an 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 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. PSC acts as agent for the purchaser, the broker-dealer and PFD in 
maintaining these plans. See "How to Buy Fund Shares." 

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., PGA IRA Cust for John Smith may 
only go into another account registered PGA 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 also 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 PSC. You may sell or exchange your Fund shares by telephone by 
calling 1-800-225-6292 between 8:00 a.m. and 8:00 p.m. Eastern Time on 
weekdays. 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 

                                      18 
<PAGE>
 
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. 

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, Individual 
Retirement Accounts (IRA's), 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 
Account Application enclosed with 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 you own TDD keyboard equipment, you can 
call our TDD number toll-free at 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 share accounts are limited to 10% of the 
value of the account at the time the plan is implemented. See "Waiver or 
Reduction of CDSC" for more information. Periodic payments of $50 or more 
will be sent to you, or any person designated by you, monthly or quarterly 
and your periodic redemptions 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 payments be made 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 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 requirement 
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.

XIV. THE FUND 

Pioneer Europe Fund is an open-end, diversified management investment company 
(commonly referred to as a mutual fund) organized as a Massachusetts business 
trust on June 22, 1990. The Fund has authorized an unlimited number of shares 
of beneficial interest. As an open-end management investment company, the 
Fund usually 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 purposes of 
electing or removing Trustees, changing fundamental investment restrictions 
or approving a management or subadvisory contract. 

The Trustees have the authority, without further shareholder approval, to 
classify and reclassify the shares of the Fund, or any additional series of 
the Fund, into one or more classes. As of the date of this Prospectus, the 
Trustees have authorized the issuance of two classes of shares, designated 
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. The Fund reserves the right to create and issue 
additional series of shares. 

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 by the Fund. 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. 

XV. 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 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 5.75%; 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. 

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 investment results will vary from time to time depending on market 
conditions, the composition of the Fund's portfolio and operating expenses of 
the Fund. 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.
