Basic information about the fund

Investment objective

Reasonable income and capital growth.

Investment strategies

The fund invests in a broad list of carefully selected, reasonably priced
securities rather than in securities whose prices reflect a premium resulting
from their current market popularity. The fund invests the major portion of its
assets in equity securities, primarily of U.S. issuers. For purposes of the
fund's investment policies, equity securities include common and preferred
stocks and convertible debt securities. Although the fund focuses on securities
that have paid dividends in the preceding 12 months, it may purchase or hold
securities that do not provide income if the fund expects them to increase in
value.


Pioneer Investment Management, Inc., the fund's investment adviser, uses a value
approach to select the fund's investments. Using this investment style, Pioneer
seeks to identify and buy securities at reasonable prices selling at substantial
discounts to their underlying values and then to hold these securities until the
market values reflect their intrinsic values. Pioneer evaluates a security's
potential value based on the company's assets and prospects for earnings growth.
In making that assessment, Pioneer employs fundamental research and due
diligence. Pioneer also considers a security's potential to provide a reasonable
amount of income. Pioneer relies on the knowledge, experience and judgment of
its own staff who have access to a wide variety of research. Factors Pioneer
looks for in selecting investments include: 

o Favorable expected returns relative to perceived risk 
o Above average potential for earnings and revenue growth 
o Low market valuations relative to earnings forecast, book value, cash flow
  and sales
o A sustainable competitive advantage, such as a brand name, customer base,
  proprietary technology or economies of scale


Pioneer focuses on the quality and price of individual issuers, not on economic
sector or market-timing strategies. The fund avoids concentrating in any one
sector or industry.


Principal risks of investing in the fund

Even though the fund seeks reasonable income and capital growth, you could lose
money on your investment or not make as much as if you invested elsewhere if: 

o The stock market goes down (this risk may be greater if you are a short-term
  investor)
o Value stocks fall out of favor with investors
o The fund's assets remain undervalued or do not have the potential value
  originally expected
o Stocks selected for income do not achieve the same return as securities
  selected for capital growth


                                                                               1

Example

This example helps you compare the costs of investing in the fund with the cost
of investing in other mutual funds. It assumes that: a) you invest $10,000 in
the fund for the time periods shown, b) you reinvest all dividends and
distributions, c) your investment has a 5% return each year and d) the fund's
operating expenses remain the same.


Although your actual costs may be higher or lower, under these assumptions your
costs would be:

Basic information about the fund 

Other investment strategies 

As discussed, the fund invests primarily in common stocks of U.S. companies to
seek reasonable income and capital growth.

This section describes additional investments that the fund may make or
strategies that it may pursue to a lesser degree to achieve the fund's goal.
Some of the fund's secondary investment policies also entail risks. To learn
more about these investments and risks, you should obtain and read the statement
of additional information (SAI).


Investments other than U.S. common stocks

The fund may invest up to 10% of its total assets (at the time of purchase) in
securities of non-U.S. issuers. The fund will not invest more than 5% of its
total assets (at the time of purchase) in the securities of emerging markets
issuers. Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers.


The fund may invest the balance of its assets in debt securities. Generally the
fund may acquire debt securities that are investment grade, but the fund may
invest up to 5% of its net assets (at the time of purchase) in lower quality
debt securities including convertible debt securities. The fund invests in debt
securities when Pioneer believes they offer the potential for capital growth, to
diversify the fund's portfolio or for greater liquidity.


Debt securities are subject to the risk of an issuer's inability to meet
principal or interest payments on its obligations. Factors which could
contribute to a decline in the market value of debt securities in the fund's
portfolio include rising interest rates or a reduction in the perceived
creditworthiness of the issuer of the securities. A debt security is investment
grade if it is rated in one of the top four categories by a nationally
recognized securities rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Lower
quality debt securities involve greater risk of loss, are subject to greater
price volatility and are less liquid, especially during periods of economic
uncertainty or change, than higher quality debt securities.


Temporary investments

Normally, the fund invests substantially all of its assets to meet its
investment objective. The fund may invest the remainder of its assets in
securities with a remaining maturity of less than one year, cash equivalents or
may hold cash. For temporary defensive purposes, the fund may depart from its
principal investment strategies and invest part or all of its assets in these
securities. During such periods, the fund may not be able to achieve its
investment objective. The fund intends to adopt a defensive strategy only when
Pioneer believes common stocks have extraordinary risks due to political or
economic factors.

<PAGE>

Short-term trading

The fund usually does not trade for short-term profits. The fund will sell an
investment, however, even if it has only been held for a short time, if it no
longer meets the fund's investment criteria. If the fund does a lot of trading,
it may incur additional operating expenses, which would reduce performance, and
could cause shareowners to incur a higher level of taxable income or capital
gains.


Derivatives

The fund may use futures, options and other derivatives. A derivative is a
security or instrument whose value is determined by reference to the value or
the change in value of one or more securities, currencies, indices or other
financial instruments. The fund does not use derivatives as a primary investment
technique and generally limits their use to hedging. However, the fund may use
derivatives for a variety of purposes, including: 

o As a hedge against adverse changes in stock market prices, interest rates or
  currency exchange rates
o As a substitute for purchasing or selling securities
o To increase the fund's return

Even a small investment in derivatives can have a significant impact on the
fund's exposure to stock market values, interest rates or currency exchange
rates. If changes in a derivative's value do not correspond to changes in the
value of the fund's other investments, the fund may not fully benefit from or
could lose money on the derivative position. In addition, some derivatives
involve risk of loss if the person who issued the derivative defaults on its
obligation. Certain derivatives may be less liquid and more difficult to value.


                                                                               5

Management

Pioneer, the fund's investment adviser,
selects the fund's investments and oversees the fund's operations.


Pioneer Group

The Pioneer Group, Inc. and its subsidiaries are engaged in financial services

Management fee

The fund pays Pioneer a fee for managing the fund and to cover the cost of
providing certain services to the fund. Pioneer's fee varies based on the
investment performance of the fund compared to the Lipper Growth and Income
Funds Index. Pioneer's annual base fee is 0.60% of the fund's average daily net
assets. The base fee can increase to a maximum of 0.70% or decrease to a minimum
of 0.50%, depending on the performance of the fund's Class A shares relative to
the index. The performance comparison is made for a rolling 36-month period.


Pioneer's fee increases or decreases depending on whether the fund's performance
is up or down more or less than that of the index. Each percentage point of
difference between the performance of the Class A shares and the index (to a
maximum of +/-10) is multiplied by a performance adjustment rate of
0.01%. As a result, the maximum annualized adjustment rate is +/-0.1%.
This performance comparison is made at the end of each month. An
appropriate percentage of this rate (based upon the number of days in the
current month) is then applied to the fund's average net assets for the entire
performance period, giving a dollar amount that will be added to (or subtracted
from) the base fee.

Pioneer Funds Distributor, Inc. is the fund's distributor. Pioneering Services
Corporation is the fund's transfer agent. The fund compensates the distributor
and transfer agent for their services. The distributor and the transfer agent
are subsidiaries of The Pioneer Group, Inc.


Year 2000

Information technology experts are concerned about computer and other electronic
systems' ability to process date-related information on and after January 1,
2000. This scenario, commonly referred to as the "Year 2000 problem," could have
an adverse impact on the fund and the provision of services to its shareowners.
Pioneer is addressing the Year 2000 problem with respect to its systems and
those used by the distributor and transfer agent. During 1999, Pioneer expects
to finish addressing all material Year 2000 issues and to participate in
industry-wide testing. The fund has obtained assurances from its other service
providers that they are taking appropriate Year 2000 measures and Pioneer is
monitoring their efforts. Although the fund does not expect the Year 2000
problem to adversely impact it, the fund cannot guarantee that its, or the
fund's service providers', efforts will be successful.

Share price
The net asset 
value per share 
calculated on the 
day of your 
transaction,
adjusted for any 
applicable sales 
charge, is often 
referred to as the
share price.

- --------------------------------------

Net asset value                                   

The fund's net asset value is the value of its portfolio of securities plus any
other assets minus its operating expenses and any other liabilities. The fund
calculates a net asset value for each class of shares every day the New York
Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern
time).


The fund generally values its portfolio securities based on market prices or
quotations. When market prices are not available or are considered by Pioneer to
be unreliable, the fund may use an asset's fair value. Fair value is determined
in accordance with procedures approved by the fund's trustees. International
securities markets may be open on days when the U.S. markets are closed. For
this reason, the values of any international securities owned by the fund could
change on a day when you cannot buy or sell shares of the fund.


You buy or sell shares at the net asset value per share calculated on the day of
your transaction, adjusted for any applicable sales charge. When you buy Class A
shares, you pay an initial sales charge. When you sell Class B or Class C
shares, you may pay a contingent deferred sales charge depending on how long you
have owned your shares.


Choosing a class of shares

The fund offers three classes of shares through this prospectus. Each class has
different sales charges and expenses, allowing you to choose the class that best
meets your needs.


Factors you should consider include:
o How long you expect to own the shares
o The expenses paid by each class
o Whether you qualify for any reduction or waiver of sales charges


Your investment professional can help you determine which class meets your
goals. Your investment firm may receive different compensation depending upon
which class you choose. If you are not a U.S. citizen and are purchasing shares
outside the U.S., you may pay different sales charges under local laws and
business practices.


Distribution plans

The fund has adopted a distribution plan for each class of shares offered
through this prospectus in accordance with Rule 12b-1 under the Investment
Company Act of 1940. Under each plan the fund pays distribution and service fees
to the distributor. Because these fees are an ongoing expense, over time they
increase the cost of your investment and your shares may cost more than shares
that are not subject to a distribution fee.

Sales charges: Class A shares

You pay the offering price when you buy Class A shares unless you qualify to
purchase shares at net asset value. You pay a lower sales charge as the size of
your investment increases. You do not pay a sales charge when you reinvest
dividends or distributions paid by the fund.


Investments of $1 million or more

You do not pay a sales charge when you purchase Class A shares if you are
investing $1 million or more, or you are a participant in certain group plans.
However, you pay a deferred sales charge if you sell your Class A shares within
one year of purchase. The sales charge is equal to 1% of your investment or your
sales proceeds, whichever is less.

Reduced sales charges

You may qualify for a reduced Class A sales charge if you own or are purchasing
shares of Pioneer mutual funds. If you or your investment professional notifies
the distributor of your eligibility for a reduced sales charge at the time of
your purchase, the distributor will credit you with the combined value (at the
current offering price) of all your Pioneer mutual fund shares and the shares of
your spouse and the shares of any children under 21. Certain trustees and
fiduciaries may also qualify for a reduced sales charge. For this purpose,
Pioneer mutual funds include any fund for which the distributor is principal
underwriter and, at the distributor's discretion, may include funds organized
outside the U.S. managed by Pioneer.

You buy Class B shares at net asset value per share without paying an initial
sales charge. However, you will pay a contingent deferred sales charge to the
distributor if you sell your Class B shares within six years of purchase. The
contingent deferred sales charge decreases as the number of years since your
purchase increases.

Conversion to Class A shares
Class B shares automatically convert into Class A shares. This helps you because
Class A shares pay lower expenses.

Your Class B shares will convert to Class A shares at the beginning of the
calendar month (calendar quarter for shares purchased before October 1, 1998)
that is eight years after the date of purchase except that: 

o Shares bought by reinvesting dividends and capital gains will convert to
  Class A shares at the same time as shares on which the dividend or
  distribution was paid
o Shares purchased by exchanging shares from another fund will convert on the
  date that the shares originally acquired would have converted into Class A
  shares

Currently, the Internal Revenue Service permits the conversion of shares to take
place without imposing a federal tax. Conversion may not occur if the Internal
Revenue Service deems it a taxable event for federal tax purposes.

Qualifying for a reduced sales charge

Initial Class A sales charge waivers

You may purchase Class A shares at net asset value (without a sales charge) or
with a reduced initial sales charge as follows. If you believe you qualify for
any of the waivers discussed below, contact the distributor. You are required to
provide written confirmation of your eligibility. You may not resell these
shares except to or on behalf of the fund.


Class A purchases at net asset value are available to:

o Current or former trustees and officers of the fund;
o Current or former partners and employees of legal counsel to the fund; 
o Current or former directors, officers, employees or sales representatives of
  The Pioneer Group, Inc. and its affiliates;
o Current or former directors, officers, employees or sales representatives of
  any subadviser or a predecessor adviser (or their affiliates) to any
  investment company for which Pioneer serves as investment adviser;
o Current or former officers, partners, employees or registered
  representatives of broker-dealers which have entered into sales agreements
  with the distributor;
o Members of the immediate families of any of the persons above; 
o Any trust, custodian, pension, profit sharing or other benefit plan of the 
  foregoing persons;
o Insurance company separate accounts;
o Certain "wrap accounts" for the benefit of clients of financial planners
  adhering to standards established by the distributor;
o Other funds and accounts for which Pioneer or any of its affiliates serve as
  investment adviser or manager;
o In connection with certain reorganization, liquidation or acquisition
  transactions involving other investment companies or personal holding
  companies;
o Certain unit investment trusts;
o Employer-sponsored retirement plans with 100 or more eligible employees or
  at least $500,000 in plan assets;
o Participants in Optional Retirement Programs if (i) your employer has
  authorized a limited number of mutual funds to participate in the program,
  (ii) all participating mutual funds sell shares to program participants at net
  asset value, (iii) your employer has agreed in writing to actively promote
  Pioneer mutual funds to program participants and (iv) the program provides for
  a matching contribution for each participant contribution.


                                                                              13
<PAGE>

Buying, exchanging and selling shares

Class A purchases at a reduced initial sales charge or net asset value are also
available to: 

Group Plans if the sponsoring organization 
o recommends purchases of Pioneer mutual funds to, 
o permits solicitation of, or 
o facilitates purchases by its employees, members or participants.


Letter of intent (Class A)

You can use a letter of intent to qualify for reduced sales charges in two
situations:
o If you plan to invest at least $50,000 (excluding any reinvestment of
  dividends and capital gain distributions) in the fund's Class A shares during
  the next 13 months
o If you include in your letter of intent the value -- at the current offering
  price -- of all of your Class A shares of the fund and all other Pioneer
  mutual fund shares held of record in the amount used to determine the
  applicable sales charge for the fund shares you plan to buy.


Completing a letter of intent does not obligate you to purchase additional
shares, but if you do not buy enough shares to qualify for the projected level
of sales charges by the end of the 13-month period (or when you sell your
shares, if earlier), the distributor will recalculate your sales charge. You
must pay the additional sales charge within 20 days after you are notified of
the recalculation or it will be deducted from your account (or your sale
proceeds). For more information regarding letters of intent, please contact your
investment professional or obtain and read the statement of additional
information.


Reinvestment (Class A)

If you sold shares of another mutual fund within the past 60 days, you may be
able to reinvest the sale proceeds from that fund in Class A shares of the fund
at net asset value without a sales charge.


To qualify:
o Your investment firm must have a sales agreement with the distributor; 
o You must demonstrate that the amount invested is from the proceeds of the sale
  of shares from another mutual fund that occurred within 60 days immediately 
  preceding your purchase;
o You paid a sales charge on the original purchase of the shares sold; and 
o The mutual fund whose shares were sold also offers net asset value purchases
  to shareowners that sell shares of a Pioneer mutual fund.

Waiver or reduction of contingent deferred sales charges (CDSC)


Class A shares that are subject to a CDSC

Purchases of Class A shares of $1 million or more, or by participants in a Group
Plan which were not subject to an initial sales charge, may be subject to a CDSC
upon redemption. A CDSC is payable to the distributor 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. However, the
CDSC is waived for redemptions of Class A shares purchased by an
employer-sponsored retirement plan qualified under Section 401 of the Internal
Revenue Code that has 1,000 or more eligible employees or at least $10 million
in plan assets.


Class A, Class B and Class C shares

The distributor may waive or reduce the CDSC for Class A shares that are subject
to a CDSC or for Class B or Class C shares if:

o The distribution results from the death of all registered account owners or a
  participant in an employer-sponsored plan. For UGMAs, UTMAs and trust accounts
  the waiver applies only upon the death of all beneficial owners;
o The distribution results from a total and permanent disability (as defined
  by Section 72 of the Internal Revenue Code) occurring after the purchase of
  the shares being sold. For UGMAs, UTMAs and trust accounts, the waiver only
  applies upon the disability of all beneficial owners;
o The distribution is made in connection with limited automatic redemptions as
  described 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);
o The distribution is from any type of IRA, 403(b) or employer-sponsored plan
  and one of the following applies:
  - It is part of a series of substantially equal periodic payments made over
    the life expectancy of the participant or the joint life expectancy of the 
    participant and his or her beneficiary (limited in any year to 10% of the
    value of the participant's account at the time the distribution amount is 
    established);
  - It is a required minimum distribution due to the attainment of age 70-1/2,

General rules on buying, exchanging and selling
your fund shares

Share price

If you place an order with your investment firm before the New York Stock
Exchange closes and your investment firm submits the order to the distributor
prior to the distributor's close of business (usually 5:30 p.m. Eastern time),
your share price will be calculated that day. Otherwise, your price per share
will be calculated at the close of the New York Stock Exchange after the
distributor receives your order. Your investment firm is responsible for
submitting your order to the distributor.


Buying

You may buy fund shares from any investment firm that has a sales agreement with
the distributor. If you do not have an investment firm, please call
1-800-225-6292 for information on how to locate an investment professional in
your area.

You can buy fund shares at the offering price. The distributor may reject any
order until it has confirmed the order in writing and received payment. The fund
reserves the right to stop offering any class of shares.


Minimum investment amounts

Your initial investment must be at least $50 for Class A shares and $1,000 for
Class B and Class C shares. Additional investments must be at least $50 for
Class A shares and $500 for Class B or Class C shares. You may qualify for lower
initial or subsequent investment minimums if you are opening a retirement plan
account, establishing an automatic investment plan or placing your trade through
your investment firm. If you have a Class A share account, you must maintain a
minimum account balance of $500. You will have at least 24 months from the date
you opened your account to achieve the $500 balance.


- --------------------------------------------------------------------------------
Retirement plan accounts


You can purchase fund shares through tax-deferred retirement plans for
individuals, businesses and tax-exempt organizations.


Your initial investment for most types of retirement plan accounts must be at
least $250. Additional investments for most types of retirement plans must be at
least $100.


You may not use the account application accompanying this prospectus to
establish a Pioneer retirement plan. You can obtain retirement plan
applications from your investment firm or by calling the Retirement Plans
Department at 1-800-622-0176.
- --------------------------------------------------------------------------------

<PAGE>

Exchanging

You may exchange your shares for shares of the same class of another Pioneer
mutual fund.


Your exchange request must be for at least $1,000 unless the fund you are
exchanging into has a different minimum. The fund allows you to exchange your
shares at net asset value without charging you either an initial or contingent
deferred sales charge at the time of the exchange. Shares you acquire as part of
an exchange will continue to be subject to any contingent deferred sales charge
that applies to the shares you originally purchased. When you ultimately sell
your shares, the date of your original purchase will determine your contingent
deferred sales charge.


Before you request an exchange, consider each fund's investment objective and
policies as described in the fund's prospectus.


Selling

Your shares will be sold at net asset value per share next calculated after the
fund receives your request in good order.


If the shares you are selling are subject to a deferred sales charge, it will be
deducted from the sale proceeds. The fund generally will send your sale proceeds
by check, bank wire or electronic funds transfer. Normally you will be paid
within seven days. If you recently sent a check to purchase the shares being
sold, the fund may delay payment of the sale proceeds until your check has
cleared. This may take up to 15 calendar days from the purchase date.


If you are selling shares from a nonretirement account or certain IRAs, you may
use any of the methods described below. If you are selling shares from a
retirement account other than an IRA, you must make your request in writing.

You may have to

  by each record owner exactly as the shares are registered

Selling shares
- --------------------------------------------------------------------------------

Normally, your investment firm will send your request to sell shares to the
fund's transfer agent. Consult your investment professional for more
information. The fund has authorized the distributor to act as its agent in the
repurchase of fund shares from qualified investment firms. The fund reserves the
right to terminate this procedure at any time.

- --------------------------------------------------------------------------------
You may sell up to $100,000 per account per day. You may sell fund shares held
in a retirement plan account by phone only if your account is an IRA. You may
not sell your shares by phone if you have changed your address (for checks) or
your bank information (for wires and transfers) in the last 30 days.


You may receive your sale proceeds:


o By check, provided the check is made payable exactly as your account is
  registered
o By bank wire or by electronic funds transfer, provided the sale proceeds are
  being sent to your bank address of record



- --------------------------------------------------------------------------------
You can sell some or all of your fund shares by writing directly to the fund
only if your account is registered in your name. Include in your request your
name, the fund's name, your fund account number, the class of shares to be sold,
the dollar amount or number of shares to be sold and any other applicable
requirements as described below. The transfer agent will send the sale proceeds
to your address of record unless you provide other instructions. Your request
must be signed by all registered owners and be in good order.

Exchange privilege
The fund and the distributor reserve the right to refuse any exchange request or
restrict, at any time without notice, the number and/or frequency of exchanges
to prevent abuses of the exchange privilege. Abuses include frequent trading in
response to short-term market fluctuations and a pattern of trading that appears
to be an attempt to "time the market." In addition, the fund and the distributor
reserve the right, at any time without notice, to charge a fee for exchanges or
to modify, limit, suspend or discontinue the exchange privilege.

Buying, exchanging and selling shares

Account options
See the account application form for more details on each of the following
options.


Automatic investment plans

You can make regular periodic investments in the fund by setting up monthly bank
drafts, government allotments, payroll deduction, a Pioneer Investomatic Plan
and other similar automatic investment plans. You may use an automatic
investment plan to establish a Class A share account with a small initial
investment. If you have a Class B or Class C share account and your balance is
at least $1,000, you may establish an automatic investment plan.


Pioneer Investomatic Plan

If you establish a Pioneer Investomatic Plan, the transfer agent will make a
periodic investment in fund shares by means of a preauthorized electronic funds
transfer from your bank account. Your plan investments are voluntary. You may
discontinue your plan at any time or change the plan's dollar amount, frequency
or investment date by calling or writing to the transfer agent. You should allow
up to 30 days for the transfer agent to establish your plan.


Automatic exchanges

You can automatically exchange your fund shares for shares of the same class of
another Pioneer mutual fund. The automatic exchange will begin on the day you
select when you complete the appropriate section of your account application or
an account options form. In order to use automatic exchange: 

o You must select exchanges on a monthly or quarterly basis 
o Both the originating and receiving accounts must have identical registrations
o The originating account has a minimum balance of $5,000

Distribution options

The fund offers three distribution options. Any fund shares you buy by
reinvesting distributions will be priced at the applicable net asset value per
share.


(1) Unless you indicate another option on your account application, any
    dividends and capital gain distributions paid to you by the fund will
    automatically be invested in additional fund shares.


(2) You may elect to have the amount of any dividends paid to you in cash and
    any capital gain distributions reinvested in additional shares.


(3) You may elect to have the full amount of any dividends and/or capital gain 
    distributions paid to you in cash.


Options (2) or (3) are not available to retirement plan accounts or accounts
with a current value of less than $500.


If your distribution check is returned to the transfer agent or you do not cash
the check for six months or more, the transfer agent may reinvest the amount of
the check in your account and automatically change the distribution option on
your account to option (1) until you request a different option in writing.
These additional shares will be purchased at the then current net asset value.


22
<PAGE>

Directed dividends

You can invest the dividends paid by one of your Pioneer mutual fund accounts in
a second Pioneer mutual fund account. The value of your second account must be
at least $1,000 ($500 for Pioneer Fund or Pioneer II). You may direct the
investment of any amount of dividends. There are no fees or charges for directed
dividends. If you have a retirement plan account, you may only direct dividends
to accounts with identical registrations.


Systematic withdrawal plans

When you establish a systematic withdrawal plan for your account, the transfer
agent will sell the number of fund shares you specify on a periodic basis and
the proceeds will be paid to you or to any person you select. You must obtain a
signature guarantee to direct payments to another person after you have
established your systematic withdrawal plan. Payments can be made either by
check or by electronic transfer to a bank account you designate.


To establish a systematic withdrawal plan:
o Your account must have a total value of at least $10,000 when you establish
  your plan
o You must request a periodic withdrawal of at least $50
o You may not request a periodic withdrawal of more than 10% of the value of
  any Class B or Class C share account (valued at the time the plan is
  implemented)


Systematic sales of fund shares may be taxable transactions for you. If you
purchase Class A shares while you are making systematic withdrawals from your
account, you may pay unnecessary sales charges.

Direct deposit

If you elect to take dividends or dividends and capital gain distributions in
cash, or if you establish a systematic withdrawal plan, you may choose to have
those cash payments deposited directly into your savings, checking or NOW bank
account.


Voluntary tax withholding

You may have the transfer agent withhold 28% of the dividends and capital gain
distributions paid from your fund account (before any reinvestment) and forward
the amount withheld to the Internal Revenue Service as a credit against your
federal income taxes. Voluntary tax withholding is not available for retirement
plan accounts or for accounts subject to backup withholding.


Reinstatement privilege for Class A shares

You may qualify for the reinstatement privilege if you recently sold all or part
of your Class A shares.


                                                                              23

Dividends and capital gains

The fund generally pays distributions of net long-term capital gains in
November. The fund generally pays dividends from any net investment income or
distributions of net short-term capital gains quarterly during March, June,
September and December. The fund may also pay dividends and distributions at
other times if necessary for the fund to avoid federal income or excise tax. If
you invest in the fund close to the time that the fund makes a capital gains
distribution, generally you will pay a higher price per share and you will pay
taxes on the amount of the capital gains distribution whether you reinvest the
distribution or receive it as cash. 


Taxes

For federal income tax purposes, your distributions from the fund's net
long-term capital gains are considered long-term capital gains and may be
taxable to you at different maximum rates depending upon their source and other
factors. Dividends and short-term capital gain distributions are taxable as
ordinary income. Dividends and distributions are taxable, whether you take
payment in cash or reinvest them to buy additional fund shares. You may also
have tax consequences (generally, a capital gain or loss) when you sell or
exchange fund shares. Each year the fund will mail to you information about your
dividends and distributions for, and the shares you sold in, the previous
calendar year.


You must provide your social security number or other taxpayer identification
number to the fund along with the certifications required by the Internal
Revenue Service when you open an account. If you do not or if it is otherwise
legally required to do so, the fund will withhold 31% "backup withholding" tax
from your dividends and distributions, sales proceeds and any other payments to
you.


You should ask your own tax adviser about any federal or state tax
considerations, including possible additional withholding taxes for non-U.S.
shareholders. You may also consult the fund's statement of additional
information for a more detailed discussion of federal income tax considerations
that may affect the fund and its shareowners.

Basic information about the fund





Investment objective

Reasonable income and capital growth.

Investment strategies
The fund invests in a broad list of carefully selected, reasonably priced
securities rather than in securities whose prices reflect a premium resulting
from their current market popularity. The fund invests the major portion of its
assets in equity securities, primarily of U.S. issuers. For purposes of the
fund's investment policies, equity securities include common and preferred
stocks and convertible debt securities. Although the fund focuses on securities
that have paid dividends in the preceding 12 months, it may purchase or hold
securities that do not provide income if the fund expects them to increase in
value.

Pioneer Investment Management, Inc., the fund's investment adviser, uses a
value approach to select the fund's investments. Using this investment style,
Pioneer seeks to identify and buy securities at reasonable prices or selling at
substantial discounts to their underlying values and then to hold these
securities until the market values reflect their intrinsic values. Pioneer
evaluates a security's potential value based on the company's assets and
prospects for earnings growth. In making that assessment, Pioneer employs
fundamental research and due diligence. Pioneer also considers a security's
potential to provide a reasonable amount of income. Pioneer relies on the
knowledge, experience and judgment of its own staff who have access to a wide
variety of research. Factors Pioneer looks for in selecting investment include:

[square bullet] Favorable expected returns relative to perceived risk

[square bullet] Above average potential for earnings and revenue growth

[square bullet] Low market valuations relative to earnings forecast, book value,
                cash flow and sales

[square bullet] A sustainable competitive advantage, such as a brand name,
                customer base, proprietary technology or economies of scale

Pioneer focuses on the quality and price of individual issuers, not on economic
sector or market-timing strategies.  The fund avoids concentrating in any one
sector or industry.

Principal risks of investing in the fund
Even though the fund seeks reasonable income and capital growth, you could lose
money on your investment or not make as much as if you invested elsewhere if:

[square bullet] The stock market goes down (this risk may be greater if you are
                a short-term investor)

[square bullet] Value stocks fall out of favor with investors

[square bullet] The fund's assets remain undervalued or do not have the
                potential value originally expected

[square bullet] Stocks selected for income do not achieve the same return as
                securities selected for capital growth

The fund's past performance

The bar chart and table indicate the risks of investing in the fund by showing
how the fund has performed in the past. The fund's performance varies from year
to year.

Class Y shares were first offered on May 3, 1999 and do not yet have a
performance record. The fund's past performance does not necessarily indicate
how it will perform in the future. As a shareowner, you may lose or make money
on your investment.

Example
This example helps you compare the costs of investing in the fund with the cost
of investing in other mutual funds. It assumes that: a) you invest $10,000 in
the fund for the time periods shown, b) you reinvest all dividends and
distributions, c) your investment has a 5% return each year and d) the fund's
operating expenses remain the same.

Although your actual costs may be higher or lower, under these assumptions your
costs would be:

Basic information about the fund





Other investment strategies
As discussed, the fund invests primarily in common stocks of U.S. companies
to seek reasonable income and capital growth.

This section describes additional investments that the fund may make or
strategies that it may pursue to a lesser degree to achieve the fund's goal.
Some of the fund's secondary investment policies also entail risks. To learn
more about these investments and risks, you should obtain and read the statement
of additional information (SAI).

Investments other than U.S. common stocks
The fund may invest up to 10% of its total assets (at the time of purchase) in
securities of non-U.S. issuers. The fund will not invest more than 5% of its
total assets (at the time of purchase) in the securities of emerging markets
issuers.  Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers.

The fund may invest the balance of its assets in debt securities. Generally
the fund may acquire debt securities that are investment grade, but the fund may
invest up to 5% of its net assets (at the time of purchase) in lower quality
debt securities including below investment grade convertible debt securities.
The fund invests in debt securities when Pioneer believes they offer the
potential for capital growth, to diversify the fund's portfolio or for greater
liquidity.

Debt securities are subject to the risk of an issuer's inability to meet
principal or interest payments on its obligations. Factors which could
contribute to a decline in the market value of debt securities in the fund's
portfolio include rising interest rates or a reduction in the perceived
creditworthiness of the issuer of the securities. A debt security is investment
grade if it is rated in one of the top four categories by a nationally
recognized securities rating organization or determined to be of equivalent
credit quality by Pioneer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. Lower
quality debt securities involve greater risk of loss, are subject to greater
price volatility and are less liquid, especially during periods of economic
uncertainty or change, than higher quality debt securities.

Temporary investments
Normally, the fund invests substantially all of its assets to meet its
investment objective. The fund may invest the remainder of its assets in
securities with a remaining maturity of less than one year, cash equivalents or
may hold cash. For temporary defensive purposes, the fund may depart from its
principal investment strategies and invest part or all of its assets in these
securities. During such periods, the fund may not be able to achieve its
investment objective. The fund intends to adopt a defensive strategy only when
Pioneer believes common stocks have extraordinary risks due to political or
economic factors.

Short-term trading
The fund usually does not trade for short-term profits. The fund will sell an
investment, however, even if it has only been held for a short time, if it no
longer meets the fund's investment criteria. If the fund does a lot of trading,
it may incur additional operating expenses, which would reduce performance, and
could cause shareowners to incur a higher level of taxable income or capital
gains.

                                       4
<PAGE>







Derivatives
The fund may use futures, options and other derivatives. A derivative is a
security or instrument whose value is determined by reference to the value or
the change in value of one or more securities, currencies, indices or other
financial instruments. The fund does not use derivatives as a primary investment
technique and generally limits their use to hedging. However, the fund may use
derivatives for a variety of purposes, including:

[square bullet] As a hedge against adverse changes in stock market prices,
                interest rates or currency exchange rates

[square bullet] As a substitute for purchasing or selling securities

[square bullet] To increase the fund's return

Even a small investment in derivatives can have a significant impact on the
fund's exposure to stock market values, interest rates or currency exchange
rates. If changes in a derivative's value do not correspond to changes in the
value of the fund's other investments, the fund may not fully benefit from or
could lose money on the derivative position. In addition, some derivatives
involve risk of loss if the person who issued the derivative defaults on its
obligation. Certain derivatives may be less liquid and more difficult to value.

Management







Pioneer, the fund's investment adviser,
selects the fund's investments and oversees the fund's operations

Pioneer Group
The Pioneer Group, Inc. and its subsidiaries are engaged in financial
services businesses in the United States and many foreign countries. As of
December 31, 1998, the firm had more than $23 billion in assets under management
worldwide including more than $22 billion in U.S. mutual funds. The firm's U.S.
mutual fund investment history includes creating this fund in 1928, one of the
first mutual funds. John F. Cogan, chairman of the board and president of The
Pioneer Group, Inc., owns approximately 14% of the firm. He is also an officer
and director of each of the Pioneer mutual funds.

Investment adviser
Pioneer manages a family of U.S. and international stock funds, bond funds and
money market funds. Pioneer is a subsidiary of The Pioneer Group, Inc. Its main
office is at 60 State Street, Boston, Massachusetts 02109.

Portfolio manager
Day-to-day management of the fund's portfolio is the responsibility of
John A. Carey. Mr. Carey is a vice president of Pioneer and the fund. He joined
Pioneer in 1979 and has over 19 years of investment experience.

Mr. Carey is supported by a team of portfolio managers and analysts who
specialize in U.S. equity securities. This team provides research for the fund
and other Pioneer mutual funds with similar investment objectives or styles.
Mr. Carey and his team operate under the supervision of Theresa A. Hamacher. Ms.
Hamacher is chief investment officer of Pioneer. She joined Pioneer in 1997 and
has been an investment professional since 1984.

                                       6
<PAGE>







Management fee
The fund pays Pioneer a fee for managing the fund and to cover the cost of
providing certain services to the fund. Pioneer's fee varies based on the
investment performance of the fund compared to the Lipper Growth and Income
Funds Index. Pioneer's annual base fee is 0.60 of the fund's average daily net
assets. The base fee can increase to a maximum of 0.70% or decrease to a
minimum of 0.50%, depending on the performance of the fund's Class A shares
relative to the index. The performance comparison is made for a rolling 36-month
period.

Pioneer's fee increases or decreases depending on whether the fund's
performance is up or down more or less than that of the index. Each percentage
point of difference between the performance of the Class A shares and the index
(to a maximum of +/-10) is multiplied by a performance adjustment rate of 0.01%.
As a result, the maximum annualized adjustment rate is +/-0.1%. This performance
comparison is made at the end of each month. An appropriate percentage of this
rate (based upon the number of days in the current month) is then applied to the
fund's average net assets for the entire performance period, giving a dollar
amount that will be added to (or subtracted from) the base fee.

Distributor and transfer agent
Pioneer Funds Distributor, Inc. is the fund's distributor. Pioneering Services
Corporation is the fund's transfer agent. The fund compensates the distributor
and transfer agent for their services. The distributor and the transfer agent
are subsidiaries of The Pioneer Group, Inc.

Year 2000
Information technology experts are concerned about computer and other electronic
systems' ability to process date-related information on and after January 1,
2000. This scenario, commonly referred to as the "Year 2000 problem," could have
an adverse impact on the fund and the provision of services to its shareowners.
Pioneer is addressing the Year 2000 problem with respect to its systems and
those used by the distributor and transfer agent. During 1999, Pioneer expects
to finish addressing all material Year 2000 issues and to participate in
industry-wide testing. The fund has obtained assurances from its other service
providers that they are taking appropriate Year 2000 measures and Pioneer is
monitoring their efforts. Although the fund does not expect the Year 2000
problem to adversely impact it, the fund cannot guarantee that its, or the
fund's service providers', efforts will be successful.

Net asset value

The fund's net asset value is the value of its portfolio of securities plus any
other assets minus its operating expenses and any other liabilities. The fund
calculates a net asset value for each class of shares every day the New York
Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern
time).

The fund generally values its portfolio securities based on market prices or
quotations. When market prices are not available or are considered by Pioneer to
be unreliable, the fund may use an asset's fair value. Fair value is determined
in accordance with procedures approved by the fund's trustees. International
securities markets may be open on days when the U.S. markets are closed. For
this reason, the values of any international securities owned by the fund could
change on a day when you cannot buy or sell shares of the fund.

You buy or sell Class Y shares at the net asset value per share calculated on
the day of your transaction.

Distribution of Class Y shares
The distributor incurs the expenses of distributing the fund's Class Y shares,
none of which are reimbursed or paid for by the fund or the Class Y shareowners.
Distribution expenses include fees paid to broker-dealers which have sales
agreements with the distributor and other parties, advertising expenses and the
cost of printing and mailing prospectuses to potential investors.

The distributor or its affiliates may make payments out of its own resources to
dealers and other persons who distribute Class Y shares. Such payments may be
based upon the value of Class Y shares sold. The distributor may impose
conditions on the payment of such fees.

Opening your account

If you are an individual or other non-institutional investor, open your Class Y
share account by completing an account application and sending it to the
transfer agent by mail or by fax. If you are any other type of investor, please
call the transfer agent to obtain a Class Y share account set-up kit and an
account number.

The transfer agent must receive your account application before you send your
initial check or federal funds wire. In addition, you must provide a bank wire
address of record when you establish your account.

If your shares are held in your investment firm's name, the options and services
available to you may be different from those discussed in this prospectus. Ask
your investment professional for more information.

Account options
Use your account application to select options and privileges for your account.
You can change your selections at any time by sending a completed account
options form to the transfer agent. You may be required to obtain a signature
guarantee to make certain changes to an existing account.

Call or write to the fund's transfer agent for account applications, account
options forms and other account information:

Pioneering Services Corporation
P.O. Box 9014
Boston, Massachusetts 02205-9014
Telephone 1-888-294-4480

Telephone transaction privileges
If your account is registered in your name, you can exchange or sell Class Y
shares by telephone. If you do not want your account to have telephone
transaction privileges, you must indicate that choice on your account
application or by writing to the transfer agent.

When you request a telephone transaction the transfer agent will try to confirm
that the request is genuine. The transfer agent records the call, requires the
caller to provide the personal identification number for the account and sends
you a written confirmation. The fund may implement other confirmation procedures
from time to time. Different procedures may apply if you have a non-U.S. account
or if your account is registered in the name of an institution, broker-dealer or
other third party.

Buying, exchanging and selling shares





General rules on buying, exchanging and selling
your fund shares

Share price
When you place an order to purchase, exchange or sell Class Y shares it must be
received in good order by the transfer agent or by your broker-dealer by the
close of regular trading on the New York Stock Exchange (currently 4:00 p.m.
Eastern time) in order to purchase shares at the price determined on that day.

If you place your order through a broker-dealer, you must place the order before
the close of regular trading on the New York Stock Exchange and your
broker-dealer must submit the order to the distributor prior to the
distributor's close of business (usually 5:30 p.m. Eastern time) for your share
price to be determined at the close of regular trading on the date your order is
received. Your broker-dealer is responsible for transmitting your order to the
distributor. In all other cases except as described below for wire transfers,
your share price will be calculated at the close of the New York Stock Exchange
after the distributor receives your order.

Buying
You can buy Class Y shares at net asset value per share. The fund does not
impose any initial, contingent deferred or asset based sales charge on Class Y
shares. The distributor may reject any order until it has confirmed it in
writing and received payment.

Minimum investment amount
Your initial Class Y share investment must be at least $5 million. This amount
may be invested in one or more of the Pioneer mutual funds that currently offer
Class Y shares. There is no minimum additional investment amount.

Waivers of the minimum investment amount
The fund will accept an initial investment of less than $5 million if:

(a)  The investment is made by a trust company or bank trust department which is
     initially investing at least $1 million in any of the Pioneer mutual funds
     and, at the time of the purchase, such assets are held in a fiduciary,
     advisory, custodial or similar capacity over which the trust company or
     bank trust department has full or shared investment discretion; or

(b)  The investment is made by an employer-sponsored retirement plan that meets
     the requirements of Sections 401, 403 or 457 of the Internal Revenue Code,
     provided thatthe number of employees covered by the plan is 5,000 or more,
     or the plan has assets of $25 million or more; or

(c)  The investment is at least $1 million in any of the Pioneer mutual funds
     and the purchaser is an insurance company separate account; or

(d)  The investment is made by an employer-sponsored retirement plan established
     for the benefit of

     (1)  employees of The Pioneer Group, Inc. or employees of its affiliates,
          or

     (2)  employees or the affiliates of broker-dealers who have a Class Y
          shares sales agreement with the distributor.

Exchanging
You may exchange your Class Y shares for the Class Y shares of another Pioneer
mutual fund.

Your exchange request must be for at least $1,000 unless the fund you are
exchanging into has a different minimum. The fund allows you to exchange your
Class Y shares at net asset value without charging you either an initial or
contingent deferred sales charge.

Before you request an exchange, consider each fund's investment objective and
policies as described in the fund's prospectus.

Selling
Your Class Y shares will be sold at net asset value per share next calculated
after the fund receives your request in good order. If a signature guarantee is
required, you must submit your request in writing.

The fund generally will send your sale proceeds by check, bank wire or
electronic funds transfer. Normally you will be paid within seven days. If you
recently purchased the shares being sold, the fund may delay payment of the sale
proceeds until your payment has cleared. This may take up to 15 calendar days
from the purchase date.

If you are selling shares from a non-retirement account or certain IRAs, you may
use any of the methods described below. If you are selling shares from a
retirement account other than an IRA, you must make your request in writing.

Buying, exchanging and selling shares





Account options

Distribution options
The fund offers three distribution options. Any fund shares you buy by
reinvesting distributions will be priced at the applicable net asset value per
share.

(1)  Unless you indicate another option on your account application, any
     dividends and capital gain distributions paid to you by the fund will
     automatically be invested in additional fund shares.

(2)  You may elect to have the amount of any dividends paid to you in cash and
     any capital gain distributions reinvested in additional shares.

(3)  You may elect to have the full amount of any dividends and/or capital gain
     distributions paid to you in cash.

Options (2) or (3) are not available to retirement plan accounts or accounts
with a current value of less than $500.

If your distribution check is returned to the transfer agent or you do not cash
the check for six months or more, the transfer agent may reinvest the amount of
the check in your account and automatically change the distribution option on
your account to option (1) until you request a different option in writing.
These additional shares will be purchased at the then current net asset value.

unions (if authorized under state law) and federal savings and loan
associations. You cannot obtain a signature guarantee from a notary public.

Fiduciaries and corporations are required to submit additional documents to sell
fund shares.

Minimum account size
The fund requires that you maintain a minimum account value of $500. If you hold
less than the minimum in your account because you have sold or exchanged some of
your shares, the fund will notify you of its intent to sell your shares and
close your account. You may avoid this by increasing the value of your account
to at least the minimum within six months of the notice from the fund.

Telephone access
You may have difficulty contacting the fund by telephone during times of market
volatility or disruption in telephone service. If you are unable to reach the
fund by telephone, you should communicate with the fund in writing.

Share certificates
Normally, your shares will remain on deposit with the transfer agent and
certificates will not be issued.

Other policies
The fund may suspend transactions in shares under certain circumstances
when trading on the New York Stock Exchange is closed or restricted, when an
emergency exists that makes it impracticable for the fund to sell or value its
portfolio securities or with the permission of the Securities and Exchange
Commission.

The fund or the distributor may revise, suspend or terminate the account options
and services available to shareowners at any time.

The fund reserves the right to stop offering Class Y shares.

Dividends, capital gains and taxes





Dividends and capital gains
The fund generally pays distributions of net long-term capital gains in
November. The fund generally pays dividends from any net investment income or
distributions of net short-term capital gains quarterly during March, June,
September and in December. The fund may also pay dividends and distributions at
other times if necessary for the fund to avoid federal income or excise tax. If
you invest in the fund close to the time that the fund makes a capital gains
distribution, generally you will pay a higher price per share and you will pay
taxes on the amount of the capital gains distribution whether you reinvest the
distribution or receive it as cash.

Taxes
For federal income tax purposes, your distributions from the fund's net
long-term capital gains are considered long-term capital gains and may be
taxable to you at different maximum rates depending upon their source and other
factors. Dividends and short-term capital gain distributions are taxable as
ordinary income. Dividends and distributions are taxable, whether you take
payment in cash or reinvest them to buy additional fund shares. You may also
have tax consequences (generally, a capital gain or loss) when you sell or
exchange fund shares. Each year the fund will mail to you information about your
dividends and distributions for, and the shares you sold in, the previous
calendar year.

You must provide your social security number or other taxpayer identification
number to the fund along with the certifications required by the Internal
Revenue Service when you open an account. If you do not or if it is otherwise
legally required to do so, the fund will withhold 31% "backup withholding" tax
from your dividends and distributions, sales proceeds and any other payments to
you.

You should ask your own tax adviser about any federal or state tax
considerations, including possible additional withholding taxes for non-U.S.
shareholders. You may also consult the fund's statement of additional
information for a more detailed discussion of federal income tax considerations
that may affect the fund and its shareowners.

1.       FUND HISTORY

The fund is a diversified open-end management investment company. The fund was
originally organized as a Delaware corporation in 1928, was reorganized as a
Massachusetts corporation in 1967, and was reorganized as a Massachusetts
business trust in 1985. It was reorganized as a Delaware business trust on May
1, 1996.

2.       INVESTMENT POLICIES, RISKS AND RESTRICTIONS

The prospectuses present the investment objective and the principal investment
strategies and risks of the fund. This section supplements the disclosure in the
fund's prospectuses and provides additional information on the fund's investment
policies or restrictions. Restrictions or policies stated as a maximum
percentage of the fund's assets are only applied immediately after a portfolio
investment to which the policy or restriction is applicable. Accordingly, any
later increase or decrease resulting from a change in values, net assets or
other circumstances will not be considered in determining whether the investment
complies with the fund's restrictions and policies.

PRIMARY INVESTMENTS

Under normal circumstances, the fund invests most of its assets in common stocks
and common stock equivalents, such as preferred stocks and securities
convertible into common stock. The fund may also invest in debt securities and
cash equivalent instruments.

ILLIQUID SECURITIES

The fund will not invest more than 15% of its net assets in illiquid and other
securities that are not readily marketable. Repurchase agreements maturing in
more than seven days will be included for purposes of the foregoing limit.
Securities subject to restrictions on resale under the Securities Act of 1933,
as amended (the "1933 Act"), are considered illiquid unless they are eligible
for resale pursuant to Rule 144A or another exemption from the registration
requirements of the 1933 Act and are determined to be liquid by Pioneer
Investment Management, Inc. ("Pioneer"), the fund's investment adviser. Pioneer
determines the liquidity of Rule 144A and other restricted securities according
to procedures adopted by the Board of Trustees. The Board of Trustees monitors
Pioneer's application of these guidelines and procedures. The inability of the
fund to dispose of illiquid investments readily or at reasonable prices could
impair the fund's ability to raise cash for redemptions or other purposes.

CONVERTIBLE DEBT SECURITIES

The fund may invest in convertible debt securities which are debt obligations
convertible at a stated exchange rate or formula into common stock or other
equity securities of or owned by the issuer. Convertible securities rank senior
to common stocks in an issuer's capital structure and consequently may be of
higher quality and entail less risk than the issuer's common stock. As with all
debt securities, the market values of convertible securities tend to increase
when interest rates decline and, conversely, tend to decline when interest rates
increase.

DEBT SECURITIES RATING CRITERIA

Investment grade debt securities are those rated "BBB" or higher by Standard &
Poor's Ratings Group ("Standard & Poor's"), the equivalent rating of other
national statistical rating organizations or determined to be of equivalent
credit quality by Pioneer. Debt securities rated BBB are considered medium grade
obligations with speculative characteristics, and adverse economic conditions or
changing circumstances may weaken the issuer's ability to pay interest and repay
principal. If the rating of an investment grade debt security falls below
investment grade, Pioneer will consider if any action is appropriate in light of
the fund's investment objective and policies.

Below investment grade debt securities are those rated "BB" and below by
Standard & Poor's or the equivalent rating of other national statistical rating
organizations. See Appendix B for a description of rating categories.

Below investment grade debt securities or comparable unrated securities are
commonly referred to as "junk bonds" and are considered predominantly
speculative and may be questionable as to principal and interest payments.
Changes in economic conditions are more likely to lead to a weakened capacity to
make principal payments and interest payments. The amount of junk bond
securities outstanding has proliferated as an increasing number of issuers have
used junk bonds for corporate financing. An economic downturn could severely
affect the ability of highly leveraged issuers to service their debt obligations
or to repay their obligations upon maturity. Factors having an adverse impact on
the market value of lower quality securities will have an adverse effect on the
fund's net asset value to the extent that it invests in such securities. In
addition, the fund may incur additional expenses to the extent it is required to
seek recovery upon a default in payment of principal or interest on its
portfolio holdings.

The secondary market for junk bond securities, which is concentrated in
relatively few market makers, may not be as liquid as the secondary market for
more highly rated securities, a factor which may have an adverse effect on the
fund's ability to dispose of a particular security when necessary to meet its
liquidity needs. Under adverse market or economic conditions, the secondary
market for junk bond securities could contract further, independent of any
specific adverse changes in the condition of a particular issuer. As a result,
the fund could find it more difficult to sell these securities or may be able to
sell the securities only at prices lower than if such securities were widely
traded. Prices realized upon the sale of such lower rated or unrated securities,
under these circumstances, may be less than the prices used in calculating the
fund's net asset value.

Since investors generally perceive that there are greater risks associated with
lower quality debt securities of the type in which the fund may invest a portion
of its assets, the yields and prices of such securities may tend to fluctuate
more than those for higher rated securities. In the lower quality segments of
the debt securities market, changes in perceptions of issuers' creditworthiness
tend to occur more frequently and in a more pronounced manner than do changes in
higher quality segments of the debt securities market, resulting in greater
yield and price volatility.

Lower rated and comparable unrated debt securities tend to offer higher yields
than higher rated securities with the same maturities because the historical
financial condition of the issuers of such securities may not have been as
strong as that of other issuers. However, lower rated securities generally
involve greater risks of loss of income and principal than higher rated
securities. Pioneer will attempt to reduce these risks through portfolio
diversification and by analysis of each issuer and its ability to make timely
payments of income and principal, as well as broad economic trends and corporate
developments.

RISKS OF NON-U.S. INVESTMENTS

To the extent that the fund invests in the securities of non-U.S. issuers, those
investments involve considerations and risks not typically associated with
investing in the securities of issuers in the U.S. These risks are heightened
with respect to investments in countries with emerging markets and economies.
The risks of investing in securities of non-U.S. issuers or issuers with
significant exposure to non-U.S. markets may be related, among other things, to
(i) differences in size, liquidity and volatility of, and the degree and manner
of regulation of, the securities markets of certain non-U.S. markets compared to
the securities markets in the U.S.; (ii) economic, political and social factors;
and (iii) foreign exchange matters, such as restrictions on the repatriation of
capital, fluctuations in exchange rates between the U.S. dollar and the
currencies in which the fund's portfolio securities are quoted or denominated,
exchange control regulations and costs associated with currency exchange. The
political and economic structures in certain non-U.S. countries, particularly
emerging markets, are expected to undergo significant evolution and rapid
development, and such countries may lack the social, political and economic
stability characteristic of more developed countries. Unanticipated political or
social developments may affect the values of the fund's investments in such
countries. The economies and securities and currency markets of many emerging
markets have experienced significant disruption and declines. There can be no
assurances that these economic and market disruptions will not continue.

FOREIGN SECURITIES MARKETS AND REGULATIONS. There may be less publicly available
information about non-U.S. markets and issuers than is available with respect to
U.S. securities and issuers. Non-U.S. companies generally are not subject to
accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to U.S. companies. The trading
markets for most non-U.S. securities are generally less liquid and subject to
greater price volatility than the markets for comparable securities in the U.S.
The markets for securities in certain emerging markets are in the earliest
stages of their development. Even the markets for relatively widely traded
securities in certain non-U.S. markets, including emerging countries, may not be
able to absorb, without price disruptions, a significant increase in trading
volume or trades of a size customarily undertaken by institutional investors in
the U.S. Additionally, market making and arbitrage activities are generally less
extensive in such markets, which may contribute to increased volatility and
reduced liquidity. The less liquid a market, the more difficult it may be for
the fund to accurately price its portfolio securities or to dispose of such
securities at the times determined by Pioneer to be appropriate. The risks
associated with reduced liquidity may be particularly acute in situations in
which the fund's operations require cash, such as in order to meet redemptions
and to pay its expenses.

ECONOMIC, POLITICAL AND SOCIAL FACTORS. Certain non-U.S. countries, including
emerging markets, may be subject to a greater degree of economic, political and
social instability than is the case in the U.S. and Western European countries.
Such instability may result from, among other things: (i) authoritarian
governments or military involvement in political and economic decision making;
(ii) popular unrest associated with demands for improved economic, political and
social conditions; (iii) internal insurgencies; (iv) hostile relations with
neighboring countries; and (v) ethnic, religious and racial disaffection and
conflict. Such economic, political and social instability could significantly
disrupt the financial markets in such countries and the ability of the issuers
in such countries to repay their obligations. Investing in emerging countries
also involves the risk of expropriation, nationalization, confiscation of assets
and property or the imposition of restrictions on foreign investments and on
repatriation of capital invested. In the event of such expropriation,
nationalization or other confiscation in any emerging country, the fund could
lose its entire investment in that country.

Certain emerging market countries restrict or control foreign investment in
their securities markets to varying degrees. These restrictions may limit the
fund's investment in those markets and may increase the expenses of the fund. In
addition, the repatriation of both investment income and capital from certain
markets in the region is subject to restrictions such as the need for certain
governmental consents. Even where there is no outright restriction on
repatriation of capital, the mechanics of repatriation may affect certain
aspects of the fund's operation.

Economies in individual non-U.S. countries may differ favorably or unfavorably
from the U.S. economy in such respects as growth of gross domestic product,
rates of inflation, currency valuation, capital reinvestment, resource
self-sufficiency and balance of payments positions. Many non-U.S. countries have
experienced substantial, and in some cases extremely high, rates of inflation
for many years. Inflation and rapid fluctuations in inflation rates have had,
and may continue to have, very negative effects on the economies and securities
markets of certain emerging countries.

Economies in emerging countries generally are dependent heavily upon
international trade and, accordingly, have been and may continue to be affected
adversely by trade barriers, exchange controls, managed adjustments in relative
currency values and other protectionist measures imposed or negotiated by the
countries with which they trade. These economies also have been, and may
continue to be, affected adversely by economic conditions in the countries with
which they trade.

CURRENCY RISKS. The value of the securities quoted or denominated in
international currencies may be adversely affected by fluctuations in the
relative currency exchange rates and by exchange control regulations. The fund's
investment performance may be negatively affected by a devaluation of a currency
in which the fund's investments are quoted or denominated. Further, the fund's
investment performance may be significantly affected, either positively or
negatively, by currency exchange rates because the U.S. dollar value of
securities quoted or denominated in another currency will increase or decrease
in response to changes in the value of such currency in relation to the U.S.
dollar.

CUSTODIAN SERVICES AND RELATED INVESTMENT COSTS. Custodial services and other
costs relating to investment in international securities markets generally are
more expensive than in the U.S. Such markets have settlement and clearance
procedures that differ from those in the U.S. In certain markets there have been
times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions. The
inability of the fund to make intended securities purchases due to settlement
problems could cause the fund to miss attractive investment opportunities.
Inability to dispose of a portfolio security caused by settlement problems could
result either in losses to the fund due to a subsequent decline in value of the
portfolio security or could result in possible liability to the fund. In
addition, security settlement and clearance procedures in some emerging
countries may not fully protect the fund against loss or theft of its assets.

WITHHOLDING AND OTHER TAXES. The fund will be subject to taxes, including
withholding taxes, on income (possibly including, in some cases, capital gains)
that are or may be imposed by certain non-U.S. countries with respect to the
fund's investments in such countries. These taxes will reduce the return
achieved by the fund. Treaties between the U.S. and such countries may not be
available to reduce the otherwise applicable tax rates.

ECONOMIC MONETARY UNION (EMU). January 1, 1999, 11 European countries adopted by
a single currency - the Euro. The conversion to the Euro is being phased in over
a three-year period. During this time, valuation, systems and other operational
problems may occur in connection with the fund's investment quoted in the Euro.
For participating countries, EMU will mean sharing a single currency and single
official interest rate and adhering to agreed upon limits on government
borrowing. Budgetary decisions will remain in the hands of each participating
country, but will be subject to each country's commitment to avoid "excessive
deficits" and other more specific budgetary criteria. A European Central Bank is
responsible for setting the official interest rate to maintain price stability
within the Euro zone.

EMU is driven by the expectation of a number of economic benefits, including
lower transaction cost, reduced exchange risk, greater competition, and a
broadening and depending of European financial markets. However, there are a
number of significant risks associated with EMU. Monetary and economic union on
this scale has never been attempted before. There is a significant degree of
uncertainty as to whether participating countries will remain committed to EMU
in the face of changing economic conditions. This uncertainty my increase the
volatility of European markets.

REAL ESTATE INVESTMENT TRUSTS ("REITS") AND ASSOCIATED RISK FACTORS

REITs are pooled investment vehicles which invest primarily in income producing
real estate or real estate related loans or interests. REITs are generally
classified as equity REITs, mortgage REITs or a combination of equity and
mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. REITs are
not taxed on income distributed to shareholders provided they comply with the
applicable requirements of the Internal Revenue Code of 1986, as amended (the
"Code"). Debt securities issued by REITs, for the most part, are general and
unsecured obligations and are subject to risks associated with REITs.

Investing in REITs involves certain unique risks in addition to those risks
associated with investing in the real estate industry in general. An equity REIT
may be affected by changes in the value of the underlying properties owned by
the REIT. A mortgage REIT may be affected by changes in interest rates and the
ability of the issuers of its portfolio mortgages to repay their obligations.
REITs are dependent upon the skills of their managers and are not diversified.
REITs are generally dependent upon maintaining cash flows to repay borrowings
and to make distributions to shareholders and are subject to the risk of default
by lessees or borrowers. REITs whose underlying assets are concentrated in
properties used by a particular industry, such as health care, are also subject
to risks associated with such industry.

REITs (especially mortgage REITs) are also subject to interest rate risks. When
interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline. If the REIT invests in adjustable rate mortgage loans the interest
rates on which are reset periodically, yields on a REIT's investments in such
loans will gradually align themselves to reflect changes in market interest
rates. This causes the value of such investments to fluctuate less dramatically
in response to interest rate fluctuations than would investments in fixed rate
obligations.

REITs may have limited financial resources, may trade less frequently and in a
limited volume and may be subject to more abrupt or erratic price movements than
larger company securities. Historically REITs have been more volatile in price
than the larger capitalization stocks included in Standard & Poor's 500 Stock
Index (the "S&P 500").

OTHER INVESTMENT COMPANIES

The fund may invest in the securities of other investment companies to the
extent that such investments are consistent with the fund's investment objective
and policies and permissible under the Investment Company Act of 1940, as
amended (the "1940 Act"). Under the 1940 Act, the fund may not acquire the
securities of other domestic or foreign investment companies if, as a result,
(i) more than 10% of the fund's total assets would be invested in securities of
other investment companies, (ii) such purchase would result in more than 3% of
the total outstanding voting securities of any one investment company being held
by the fund, or (iii) more than 5% of the fund's total assets would be invested
in any one investment company. These limitations do not apply to the purchase of
shares of any investment company in connection with a merger, consolidation,
reorganization or acquisition of substantially all the assets of another
investment company. The fund will not invest in other investment companies for
which Pioneer or any of its affiliates act as an investment adviser or
distributor.

The fund, as a holder of the securities of other investment companies, will bear
its pro rata portion of the other investment companies' expenses, including
advisory fees. These expenses are in addition to the direct expenses of the
fund's own operations.

REPURCHASE AGREEMENTS

The fund may enter into repurchase agreements with broker-dealers, member banks
of the Federal Reserve System and other financial institutions. Repurchase
agreements are arrangements under which the fund purchases securities and the
seller agrees to repurchase the securities within a specific time and at a
specific price. The repurchase price is generally higher than the fund's
purchase price, with the difference being income to the fund. The Board of
Trustees reviews and monitors the creditworthiness of any institution which
enters into a repurchase agreement with the fund. The counterparty's obligations
under the repurchase agreement are collateralized with U.S. Treasury and/or
agency obligations with a market value of not less than 100% of the obligations,
valued daily. Collateral is held by the fund's custodian in a segregated,
safekeeping account for the benefit of the fund. Repurchase agreements afford
the fund an opportunity to earn income on temporarily available cash at low
risk. In the event of commencement of bankruptcy or insolvency proceedings with
respect to the seller of the security before repurchase of the security under a
repurchase agreement, the fund may encounter delay and incur costs before being
able to sell the security. Such a delay may involve loss of interest or a
decline in price of the security. If the court characterizes the transaction as
a loan and the fund has not perfected a security interest in the security, the
fund may be required to return the security to the seller's estate and be
treated as an unsecured creditor of the seller. As an unsecured creditor, the
fund would be at risk of losing some or all of the principal and interest
involved in the transaction.

SHORT SALES AGAINST THE BOX

The fund may sell securities "short against the box." A short sale involves the
fund borrowing securities from a broker and selling the borrowed securities. The
fund has an obligation to return securities identical to the borrowed securities
to the broker. In a short sale against the box, the fund at all times owns an
equal amount of the security sold short or securities convertible into or
exchangeable for, with or without payment of additional consideration, an equal
amount of the security sold short. The fund intends to use short sales against
the box to hedge. For example, when the fund believes that the price of a
current portfolio security may decline, the fund may use a short sale against
the box to lock in a sale price for a security rather than selling the security
immediately. In such a case, any future losses in the fund's long position
should be offset by a gain in the short position and, conversely, any gain in
the long position should be reduced by a loss in the short position.

If the fund effects a short sale against the box at a time when it has an
unrealized gain on the security, it may be required to recognize that gain as if
it had actually sold the security (a "constructive sale") on the date it effects
the short sale. However, such constructive sale treatment may not apply if the
fund closes out the short sale with securities other than the appreciated
securities held at the time of the short sale provided that certain other
conditions are satisfied. Uncertainty regarding certain tax consequences of
effecting short sales may limit the extent to which the fund may make short
sales against the box.

ASSET SEGREGATION

The 1940 Act requires that the fund segregate assets in connection with certain
types of transactions that may have the effect of leveraging the fund's
portfolio. If the fund enters into a transaction requiring segregation, such as
a forward commitment, the custodian or Pioneer will segregate liquid assets in
an amount required to comply with the 1940 Act. Such segregated assets will be
valued at market daily. If the aggregate value of such segregated assets
declines below the aggregate value required to satisfy the 1940 Act, additional
liquid assets will be segregated.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

The fund may purchase securities, including U.S. government securities, on a
when-issued basis or may purchase or sell securities for delayed delivery. In
such transactions, delivery of the securities occurs beyond the normal
settlement period, but no payment or delivery is made by the fund prior to the
actual delivery or payment by the other party to the transaction. The purchase
of securities on a when-issued or delayed delivery basis involves the risk that
the value of the securities purchased will decline prior to the settlement date.
The sale of securities for delayed delivery involves the risk that the prices
available in the market on the delivery date may be greater than those obtained
in the sale transaction. When-issued and delayed delivery transactions will be
fully collateralized by segregated liquid assets. See "Asset Segregation."

PORTFOLIO TURNOVER

It is the policy of the fund not to engage in trading for short-term profits
although portfolio turnover rate is not considered a limiting factor in the
execution of investment decisions for the fund. See Appendix A for the fund's
annual portfolio turnover rate.

FOREIGN CURRENCY TRANSACTIONS

The fund may engage in foreign currency transactions. These transactions may be
conducted at the prevailing spot rate for purchasing or selling currency in the
foreign exchange market. The fund also has authority to enter into forward
foreign currency exchange contracts involving currencies of the different
countries in which the fund invests as a hedge against possible variations in
the foreign exchange rates between these currencies and the U.S. dollar. This is
accomplished through contractual agreements to purchase or sell a specified
currency at a specified future date and price set at the time of the contract.

Transaction hedging is the purchase or sale of forward foreign currency
contracts with respect to specific receivables or payables of the fund, accrued
in connection with the purchase and sale of its portfolio securities quoted in
foreign currencies. Portfolio hedging is the use of forward foreign currency
contracts to offset portfolio security positions denominated or quoted in such
foreign currencies. There is no guarantee that the fund will be engaged in
hedging activities when adverse exchange rate movements occur. The fund will not
attempt to hedge all of its foreign portfolio positions and will enter into such
transactions only to the extent, if any, deemed appropriate by Pioneer.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also limit the opportunity
for gain if the value of the hedged currency should rise. Moreover, it may not
be possible for the fund to hedge against a devaluation that is so generally
anticipated that the fund is not able to contract to sell the currency at a
price above the devaluation level it anticipates.

The cost to the fund of engaging in foreign currency transactions varies with
such factors as the currency involved, the size of the contract, the length of
the contract period, differences in interest rates between the two currencies
and the market conditions then prevailing. Since transactions in foreign
currency and forward contracts are usually conducted on a principal basis, no
fees or commissions are involved. The fund may close out a forward position in a
currency by selling the forward contract or by entering into an offsetting
forward contract.

The precise matching of the forward contract amounts and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures. Using forward contracts to
protect the value of the fund's portfolio securities against a decline in the
value of a currency does not eliminate fluctuations in the underlying prices of
the securities. It simply establishes a rate of exchange which the fund can
achieve at some future point in time. The precise projection of short-term
currency market movements is not possible, and short-term hedging provides a
means of fixing the U.S. dollar value of only a portion of the fund's foreign
assets.

While the fund will enter into forward contracts to reduce currency exchange
rate risks, transactions in such contracts involve certain other risks. While
the fund may benefit from such transactions, unanticipated changes in currency
prices may result in a poorer overall performance for the fund than if it had
not engaged in any such transactions. Moreover, there may be imperfect
correlation between the fund's portfolio holdings of securities quoted or
denominated in a particular currency and forward contracts entered into by the
fund. Such imperfect correlation may cause the fund to sustain losses which will
prevent the fund from achieving a complete hedge or expose the fund to risk of
foreign exchange loss.

Over-the-counter markets for trading foreign forward currency contracts offer
less protection against defaults than is available when trading in currency
instruments on an exchange. Since a forward foreign currency exchange contract
is not guaranteed by an exchange or clearinghouse, a default on the contract
would deprive the fund of unrealized profits or force the fund to cover its
commitments for purchase or resale, if any, at the current market price.

If the fund enters into a forward contract to purchase foreign currency, the
custodian or Pioneer will segregate liquid assets. See "Asset Segregation."

OPTIONS ON FOREIGN CURRENCIES

The fund may purchase and write options on foreign currencies for hedging
purposes in a manner similar to that of transactions in forward contracts. For
example, a decline in the dollar value of a foreign currency in which portfolio
securities are quoted or denominated will reduce the dollar value of such
securities, even if their value in the foreign currency remains constant. In an
attempt to protect against such decreases in the value of portfolio securities,
the fund may purchase put options on the foreign currency. If the value of the
currency declines, the fund will have the right to sell such currency for a
fixed amount of dollars which exceeds the market value of such currency. This
would result in a gain that may offset, in whole or in part, the negative effect
of currency depreciation on the value of the fund's securities quoted or
denominated in that currency.

Conversely, if a rise in the dollar value of a currency is projected for those
securities to be acquired, thereby increasing the cost of such securities, the
fund may purchase call options on such currency. If the value of such currency
increases, the purchase of such call options would enable the fund to purchase
currency for a fixed amount of dollars which is less than the market value of
such currency. Such a purchase would result in a gain that may offset, at least
partially, the effect of any currency related increase in the price of
securities the fund intends to acquire. As in the case of other types of options
transactions, however, the benefit the fund derives from purchasing foreign
currency options will be reduced by the amount of the premium and related
transaction costs. In addition, if currency exchange rates do not move in the
direction or to the extent anticipated, the fund could sustain losses on
transactions in foreign currency options which would deprive it of a portion or
all of the benefits of advantageous changes in such rates.

The fund may also write options on foreign currencies for hedging purposes. For
example, if the fund anticipated a decline in the dollar value of securities
quoted or denominated in a foreign currency because of declining exchange rates,
it could, instead of purchasing a put option, write a covered call option on the
relevant currency. If the expected decline occurs, the option will most likely
not be exercised, and the decrease in value of portfolio securities will be
partially offset by the amount of the premium received by the fund.

Similarly, the fund could write a put option on the relevant currency, instead
of purchasing a call option, to hedge against an anticipated increase in the
dollar cost of securities to be acquired. If exchange rates move in the manner
projected, the put option will expire unexercised and allow the fund to offset
such increased cost up to the amount of the premium. However, as in the case of
other types of options transactions, the writing of a foreign currency option
will constitute only a partial hedge up to the amount of the premium, only if
rates move in the expected direction. If unanticipated exchange rate
fluctuations occur, the option may be exercised and the fund would be required
to purchase or sell the underlying currency at a loss which may not be fully
offset by the amount of the premium. As a result of writing options on foreign
currencies, the fund also may be required to forego all or a portion of the
benefits which might otherwise have been obtained from favorable movements in
currency exchange rates.

A call option written on foreign currency by the fund is "covered" if the fund
owns the underlying foreign currency subject to the call, or if it has an
absolute and immediate right to acquire that foreign currency without additional
cash consideration. A call option is also covered if the fund holds a call on
the same foreign currency for the same principal amount as the call written
where the exercise price of the call held is (a) equal to or less than the
exercise price of the call written or (b) greater than the exercise price of the
call written if the amount of the difference is maintained by the fund in cash
or liquid securities. See "Asset Segregation."

The fund may close out its position in a currency option by either selling the
option it has purchased or entering into an offsetting option. An
exchange-traded options position may be closed out only on an options exchange
which provides a secondary market for an option of the same series. Although the
fund will generally purchase or write only those options for which there appears
to be an active secondary market, there is no assurance that a liquid secondary
market on an exchange will exist for any particular option, or at any particular
time. For some options no secondary market on an exchange may exist. In such
event, it might not be possible to effect closing transactions in particular
options, with the result that the fund would have to exercise its options in
order to realize any profit and would incur transaction costs upon the sale of
underlying currencies pursuant to the exercise of put options. If the fund as a
covered call option writer is unable to effect a closing purchase transaction in
a secondary market, it will not be able to sell the underlying currency (or
security quoted or denominated in that currency) until the option expires or it
delivers the underlying currency upon exercise.

The fund may purchase and write over-the-counter options to the extent
consistent with its limitation on investments in illiquid securities. Trading in
over-the-counter options is subject to the risk that the other party will be
unable or unwilling to close out options purchased or written by the fund.

OPTIONS ON SECURITIES AND SECURITIES INDICES

The fund may purchase put and call options on any security in which it may
invest or options on any securities index based on securities in which it may
invest. The fund would also be able to enter into closing sale transactions in
order to realize gains or minimize losses on options it has purchased.

WRITING CALL AND PUT OPTIONS ON SECURITIES. A call option written by the fund
obligates the fund to sell specified securities to the holder of the option at a
specified price if the option is exercised at any time before the expiration
date. All call options written by the fund are covered, which means that the
fund will own the securities subject to the options as long as the options are
outstanding, or the fund will use the other methods described below. The fund's
purpose in writing covered call options is to realize greater income than would
be realized on portfolio securities transactions alone. However, the fund may
forego the opportunity to profit from an increase in the market price of the
underlying security.

A put option written by the fund would obligate the fund to purchase specified
securities from the option holder at a specified price if the option is
exercised at any time before the expiration date. All put options written by the
fund would be covered, which means that the fund would have segregated assets
with a value at least equal to the exercise price of the put option. The purpose
of writing such options is to generate additional income for the fund. However,
in return for the option premium, the fund accepts the risk that it may be
required to purchase the underlying security at a price in excess of its market
value at the time of purchase.

Call and put options written by the fund will also be considered to be covered
to the extent that the fund's liabilities under such options are wholly or
partially offset by its rights under call and put options purchased by the fund.
In addition, a written call option or put may be covered by entering into an
offsetting forward contract and/or by purchasing an offsetting option or any
other option which, by virtue of its exercise price or otherwise, reduces the
fund's net exposure on its written option position.

WRITING CALL AND PUT OPTIONS ON SECURITIES INDICES. The fund may also write
(sell) covered call and put options on any securities index composed of
securities in which it may invest. Options on securities indices are similar to
options on securities, except that the exercise of securities index options
requires cash payments and does not involve the actual purchase or sale of
securities. In addition, securities index options are designed to reflect price
fluctuations in a group of securities or segments of the securities market
rather than price fluctuations in a single security.

The fund may cover call options on a securities index by owning securities whose
price changes are expected to be similar to those of the underlying index, or by
having an absolute and immediate right to acquire such securities without
additional cash consideration (or for additional consideration if cash in such
amount is segregated) upon conversion or exchange of other securities in its
portfolio. The fund may cover call and put options on a securities index by
segregated assets with a value equal to the exercise price.

PURCHASING CALL AND PUT OPTIONS. The fund would normally purchase call options
in anticipation of an increase in the market value of securities of the type in
which it may invest. The purchase of a call option would entitle the fund, in
return for the premium paid, to purchase specified securities at a specified
price during the option period. The fund would ordinarily realize a gain if,
during the option period, the value of such securities exceeded the sum of the
exercise price, the premium paid and transaction costs; otherwise the fund would
realize either no gain or a loss on the purchase of the call option.

The fund would normally purchase put options in anticipation of a decline in the
market value of securities in its portfolio ("protective puts") or in securities
in which it may invest. The purchase of a put option would entitle the fund, in
exchange for the premium paid, to sell specified securities at a specified price
during the option period. The purchase of protective puts is designed to offset
or hedge against a decline in the market value of the fund's securities. Put
options may also be purchased by the fund for the purpose of affirmatively
benefiting from a decline in the price of securities which it does not own. The
fund would ordinarily realize a gain if, during the option period, the value of
the underlying securities decreased below the exercise price sufficiently to
more than cover the premium and transaction costs; otherwise the fund would
realize either no gain or a loss on the purchase of the put option. Gains and
losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of the underlying portfolio securities.

The fund may terminate its obligations under an exchange-traded call or put
option by purchasing an option identical to the one it has written. Obligations
under over-the-counter options may be terminated only by entering into an
offsetting transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

RISKS OF TRADING OPTIONS. There is no assurance that a liquid secondary market
on an options exchange will exist for any particular exchange-traded option, or
at any particular time. If the fund is unable to effect a closing purchase
transaction with respect to covered options it has written, the fund will not be
able to sell the underlying securities or dispose of its segregated assets until
the options expire or are exercised. Similarly, if the fund is unable to effect
a closing sale transaction with respect to options it has purchased, it will
have to exercise the options in order to realize any profit and will incur
transaction costs upon the purchase or sale of underlying securities.

Reasons for the absence of a liquid secondary market on an exchange include the
following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation (the "OCC")
may not at all times be adequate to handle current trading volume; or (vi) one
or more exchanges could, for economic or other reasons, decide or be compelled
at some future date to discontinue the trading of options (or a particular class
or series of options), in which event the secondary market on that exchange (or
in that class or series of options) would cease to exist, although outstanding
options on that exchange, if any, that had been issued by the OCC as a result of
trades on that exchange would continue to be exercisable in accordance with
their terms.

The fund may purchase and sell both options that are traded on U.S. and foreign
exchanges and options traded over the counter with broker-dealers who make
markets in these options. The ability to terminate over-the-counter options is
more limited than with exchange-traded options and may involve the risk that
broker-dealers participating in such transactions will not fulfill their
obligations. Until such time as the staff of the Securities and Exchange
Commission (the "SEC") changes its position, the fund will treat purchased
over-the-counter options and all assets used to cover written over-the-counter
options as illiquid securities, except that with respect to options written with
primary dealers in U.S. Government securities pursuant to an agreement requiring
a closing purchase transaction at a formula price, the amount of illiquid
securities may be calculated with reference to the formula.

Transactions by the fund in options on securities and indices will be subject to
limitations established by each of the exchanges, boards of trade or other
trading facilities governing the maximum number of options in each class which
may be written or purchased by a single investor or group of investors acting in
concert. Thus, the number of options which the fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
Pioneer. An exchange, board of trade or other trading facility may order the
liquidations of positions found to be in excess of these limits, and it may
impose certain other sanctions.

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 protective
puts for hedging purposes depends in part on Pioneer's ability to predict future
price fluctuations and the degree of correlation between the options and
securities markets.

The hours of trading for options may not conform to the hours during which the
underlying securities are traded. To the extent that the options markets close
before the markets for the underlying securities, significant price movements
can take place in the underlying markets that cannot be reflected in the options
markets.

In addition to the risks of imperfect correlation between the fund's portfolio
and the index underlying the option, the purchase of securities index options
involves the risk that the premium and transaction costs paid by the fund in
purchasing an option will be lost. This could occur as a result of unanticipated
movements in the price of the securities comprising the securities index on
which the option is based.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

To hedge against changes in securities prices or currency exchange rates or to
seek to increase total return, the fund may purchase and sell various kinds of
futures contracts, and purchase and write (sell) call and put options on any of
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, foreign currencies and other financial
instruments and indices. The fund will engage in futures and related options
transactions for bona fide hedging and non-hedging purposes as described below.
All futures contracts entered into by the fund are traded on U.S. exchanges or
boards of trade that are licensed and regulated by the Commodity Futures Trading
Commission (the "CFTC") or on foreign exchanges.

FUTURES CONTRACTS. A futures contract may generally be described as an agreement
between two parties to buy and sell particular financial instruments for an
agreed price during a designated month (or to deliver the final cash settlement
price, in the case of a contract relating to an index or otherwise not calling
for physical delivery at the end of trading in the contract).

When interest rates are rising or securities prices are falling, the fund can
seek to offset a decline in the value of its current portfolio securities
through the sale of futures contracts. When interest rates are falling or
securities prices are rising, the fund, through the purchase of futures
contracts, can attempt to secure better rates or prices than might later be
available in the market when it effects anticipated purchases. Similarly, the
fund can sell futures contracts on a specified currency to protect against a
decline in the value of such currency and a decline in the value of its
portfolio securities which are denominated in such currency. The fund can
purchase futures contracts on a foreign currency to establish the price in U.S.
dollars of a security denominated in such currency that the fund has acquired or
expects to acquire.

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting transactions which may result in a profit
or a loss. While futures contracts on securities or currency will usually be
liquidated in this manner, the fund may instead make, or take, delivery of the
underlying securities or currency whenever it appears economically advantageous
to do so. A clearing corporation associated with the exchange on which futures
on securities or currency are traded guarantees that, if still open, the sale or
purchase will be performed on the settlement date.

HEDGING STRATEGIES. Hedging, by use of futures contracts, seeks to establish
with more certainty the effective price, rate of return and currency exchange
rate on portfolio securities and securities that the fund owns or proposes to
acquire. The fund may, for example, take a "short" position in the futures
market by selling futures contracts in order to hedge against an anticipated
rise in interest rates or a decline in market prices or foreign currency rates
that would adversely affect the value of the fund's portfolio securities. Such
futures contracts may include contracts for the future delivery of securities
held by the fund or securities with characteristics similar to those of the
fund's portfolio securities. Similarly, the fund may sell futures contracts in a
foreign currency in which its portfolio securities are denominated or in one
currency to hedge against fluctuations in the value of securities denominated in
a different currency if there is an established historical pattern of
correlation between the two currencies. If, in the opinion of Pioneer, there is
a sufficient degree of correlation between price trends for the fund's portfolio
securities and futures contracts based on other financial instruments,
securities indices or other indices, the fund may also enter into such futures
contracts as part of its hedging strategies. Although under some circumstances
prices of securities in the fund's portfolio may be more or less volatile than
prices of such futures contracts, Pioneer will attempt to estimate the extent of
this volatility difference based on historical patterns and compensate for any
such differential by having the fund enter into a greater or lesser number of
futures contracts or by attempting to achieve only a partial hedge against price
changes affecting the fund's portfolio securities. When hedging of this
character is successful, any depreciation in the value of portfolio securities
will be substantially offset by appreciation in the value of the futures
position. On the other hand, any unanticipated appreciation in the value of the
fund's portfolio securities would be substantially offset by a decline in the
value of the futures position.

On other occasions, the fund may take a "long" position by purchasing futures
contracts. This may be done, for example, when the fund anticipates the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices or currency exchange rates then available in the applicable
market to be less favorable than prices or rates that are currently available.

OPTIONS ON FUTURES CONTRACTS. The acquisition of put and call options on futures
contracts will give the fund the right (but not the obligation) for a specified
price to sell or to purchase, respectively, the underlying futures contract at
any time during the option period. As the purchaser of an option on a futures
contract, the fund obtains the benefit of the futures position if prices move in
a favorable direction but limits its risk of loss in the event of an unfavorable
price movement to the loss of the premium and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the fund's assets. By writing a call
option, the fund becomes obligated, in exchange for the premium, to sell a
futures contract (if the option is exercised), which may have a value higher
than the exercise price. Conversely, the writing of a put option on a futures
contract generates a premium which may partially offset an increase in the price
of securities that the fund intends to purchase. However, the fund becomes
obligated to purchase a futures contract (if the option is exercised) which may
have a value lower than the exercise price. Thus, 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 will incur transaction costs in connection
with the writing of options on futures.

The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option on the same series. There
is no guarantee that such closing transactions can be effected. The fund's
ability to establish and close out positions on such options will be subject to
the development and maintenance of a liquid market.

OTHER CONSIDERATIONS. The fund will engage in futures and related options
transactions only for bona fide hedging or non-hedging purposes in accordance
with CFTC regulations which permit principals of an investment company
registered under the 1940 Act to engage in such transactions without registering
as commodity pool operators. The fund will determine that the price fluctuations
in the futures contracts and options on futures used for hedging purposes are
substantially related to price fluctuations in securities held by the fund or
which the fund expects to purchase. Except as stated below, the fund's futures
transactions will be entered into for traditional hedging purposes--i.e.,
futures contracts will be sold to protect against a decline in the price of
securities (or the currency in which they are denominated) that the fund owns,
or futures contracts will be purchased to protect the fund against an increase
in the price of securities (or the currency in which they are denominated) it
intends to purchase. As evidence of this hedging intent, the fund expects that
on 75% or more of the occasions on which it takes a long futures or option
position (involving the purchase of futures contracts), the fund will have
purchased, or will be in the process of purchasing, equivalent amounts of
related securities or assets quoted or denominated in the related currency in
the cash market at the time when the futures or option position is closed out.
However, in particular cases, when it is economically advantageous for the fund
to do so, a long futures position may be terminated or an option may expire
without the corresponding purchase of securities or other assets.

As an alternative to literal compliance with the bona fide hedging definition, a
CFTC regulation permits the fund to elect to comply with a different test, under
which the sum of the amounts of initial margin deposits on the fund's existing
non-hedging futures contracts and premiums paid for options on futures entered
into for non-hedging purposes (net of the amount the positions are "in the
money") would not exceed 5% of the market value of the fund's total assets. The
fund will engage in transactions in futures contracts and related options only
to the extent such transactions are consistent with the requirements of the Code
for maintaining its qualification as a regulated investment company for federal
income tax purposes.

Futures contracts and related options 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.

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, securities prices or currency exchange
rates may result in a poorer overall performance for the fund than if it had not
entered into any futures contracts or options transactions. 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. It is not possible to hedge fully or
perfectly against the effect of currency fluctuations on the value of foreign
securities because currency movements impact the value of different securities
in differing degrees.

WARRANTS

The fund may invest in warrants, which are securities permitting, but not
obligating, their holder to subscribe for other securities. Warrants do not
carry with them the right to dividends or voting rights with respect to the
securities that they entitle their holders to purchase, and they do not
represent any rights in the assets of the issuer. As a result, an investment in
warrants may be considered more speculative than certain other types of
investments. In addition, the value of a warrant does not necessarily change
with the value of the underlying securities, and a warrant expires worthless if
it is not exercised on or prior to its expiration date.

LENDING OF PORTFOLIO SECURITIES

The fund may lend portfolio securities to member firms of the New York Stock
Exchange (the "Exchange") under agreements which require that the loans be
secured continuously by collateral in cash, cash equivalents or U.S. Treasury
bills maintained on a current basis at an amount at least equal to the market
value of the securities loaned. The fund continues to receive the equivalent of
the interest or dividends paid by the issuer on the securities loaned as well as
the benefit of an increase and the detriment of any decrease in the market value
of the securities loaned and would also receive compensation based on investment
of the collateral. The fund would not, however, have the right to vote any
securities having voting rights during the existence of the loan, but would call
the loan in anticipation of an important vote to be taken among holders of the
securities or of the giving or withholding of consent on a material matter
affecting the investment.

As with other extensions of credit, there are risks of delay in recovery or even
loss of rights in the collateral should the borrower of the securities fail
financially. The fund will lend portfolio securities only to firms that have
been approved in advance by the Board of Trustees, which will monitor the
creditworthiness of any such firms. At no time would the value of the securities
loaned exceed 30% of the value of the fund's total assets.

INVESTMENT RESTRICTIONS

The fund does not intend to enter into any reverse repurchase agreements or
dollar rolls, lend portfolio securities or invest in securities index put and
call warrants, as described in fundamental investment restrictions (1), (2), (7)
and (8), during the coming year. In addition, in compliance with an informal
position taken by the staff of the SEC regarding leverage, the fund will not
purchase securities during the coming year at any time that outstanding
borrowings exceed 5% of the fund's total assets.

FUNDAMENTAL INVESTMENT RESTRICTIONS. The fund has adopted certain investment
restrictions which, along with the fund's investment objective, may not be
changed without the affirmative vote of the holders of a "majority of the
outstanding voting securities" (as defined in the 1940 Act) of the fund. The
fund may not:

(1) Issue senior securities, except as permitted by the fund's borrowing,
lending and commodity restrictions, and for purposes of this restriction, the
issuance of shares of beneficial interest in multiple classes or series, the
purchase or sale of options, futures contracts and options on futures contracts,
forward commitments, forward foreign exchange contracts, repurchase agreements,
fully covered reverse repurchase agreements, dollar rolls, swaps and any other
financial transaction entered into pursuant to the fund's investment policies as
described in the prospectus and this statement of additional information and in
accordance with applicable SEC pronouncements, as well as the pledge, mortgage
or hypothecation of the fund's assets within the meaning of the fund's
fundamental investment restriction regarding pledging, are not deemed to be
senior securities.

(2) Borrow money, except from banks as a temporary measure to facilitate the
meeting of redemption requests or for extraordinary or emergency purposes and
except pursuant to reverse repurchase agreements or dollar rolls, in all cases
in amounts not exceeding 10% of the fund's total assets (including the amount
borrowed) taken at market value. The fund will not use leverage to attempt to
increase income. The fund will not purchase securities while outstanding
borrowings (including reverse repurchase agreements and dollar rolls) exceed 10%
of the fund's total assets.

(3) Guarantee the securities of any other company, or mortgage, pledge,
hypothecate or assign or otherwise encumber as security for indebtedness its
securities or receivables in an amount exceeding the amount of the borrowing
secured thereby.

(4) Purchase securities of a company if the purchase would result in the fund's
having more than 5% of the value of its total assets invested in securities of
such company.

(5) Purchase securities of a company if the purchase would result in the fund's
owning more than 10% of the outstanding voting securities of such company.

(6) Act as an underwriter, except as it may deemed to be an underwriter in a
sale of restricted securities held in its portfolio.

(7) Make loans, except by purchase of debt obligations in which the fund may
invest consistent with its investment policies, by entering into repurchase
agreements or through the lending of portfolio securities, in each case only to
the extent permitted by the prospectus and this statement of additional
information.

(8) Invest in real estate, commodities or commodity contracts, except that the
fund may invest in financial futures contracts and related options and in any
other financial instruments which may be deemed to be commodities or commodity
contracts in which the fund is not prohibited from investing by the Commodity
Exchange Act and the rules and regulations thereunder.

(9)  Purchase securities on margin or effect short sales of securities.

(10) Purchase securities for the purpose of controlling management of other
companies.

(11) Acquire the securities of any other domestic or foreign investment company
or investment fund (except in connection with a plan of merger or consolidation
with or acquisition of substantially all the assets of such other investment
company); provided, however, that nothing herein contained shall prevent the
fund from investing in the securities issued by a real estate investment trust,
provided that such trust shall not be permitted to invest in real estate or
interests in real estate other than mortgages or other security interests.

NON-FUNDAMENTAL INVESTMENT RESTRICTIONS. In connection with the registration of
the fund's shares for sale in the Federal Republic of Germany, Austria or
Switzerland, the fund agreed to comply with certain restrictions. Under the laws
of those countries, the fund may not, without the prior approval of its
shareholders:

(i) Invest in the securities of any other domestic or foreign investment company
or investment fund, except in connection with a plan of merger or consolidation
with or acquisition of substantially all the assets of such other investment
company or investment fund;

(ii) Purchase or sell real estate, or any interest therein, and real estate
mortgage loans, except that the fund may invest in securities of corporate or
governmental entities secured by real estate or marketable interests therein or
securities issued by companies (other than real estate limited partnerships,
real estate investment trusts and real estate funds) that invest in real estate
or interests therein;

(iii) Borrow money in amounts exceeding 10% of the fund's total assets
(including the amount borrowed) taken at market value;

(iv) Pledge, mortgage or hypothecate its assets in amounts exceeding 10% of
the fund's total assets taken at market value;

(v) Purchase securities on margin or make short sales;

(vi) Redeem its securities in-kind; or

(vii) Invest in interests in oil, gas or other mineral exploration or
development leases or programs.

Further, as long as the fund is registered in Switzerland, the fund may not,
under the laws of that country, without the prior approval of its shareholders:

(a) Purchase gold or silver bullion, coins or other precious metals or purchase
or sell futures contracts or options on any such precious metals;

(b) Invest more than 10% of its total assets in the securities of any one

SHARE OWNERSHIP

See Appendix A for annual information on the ownership of fund shares by the
Trustees, the fund's officers and owners in excess of 5% of any class of shares
of the fund.

COMPENSATION OF OFFICERS AND TRUSTEES

The fund pays no salaries or compensation to any of its officers. The fund
compensates each Trustee who is not affiliated with PGI, Pioneer, PFD or PSC
with a base fee, a variable fee calculated on the basis of average net assets of
the fund, per meeting fees, and annual committee participation fees for each
committee member or chairperson that are based on percentages of his or her
aggregate annual fee. See the fee table in Appendix A.

SALES LOADS. Current and former Trustees and officers of the fund and other
qualifying persons may purchase the fund's Class A shares without an initial
sales charge.

4.   INVESTMENT ADVISER

The fund has contracted with Pioneer to act as its investment adviser. Pioneer
is a wholly owned subsidiary of PGI. PGI is engaged in the financial services
business in the U.S. and other countries. Certain Trustees or officers of the
fund are also directors and/or officers of PGI and its subsidiaries (see
management biographies above).

As the fund's investment adviser, Pioneer provides the fund with investment
research, advice and supervision and furnishes an investment program for the
fund consistent with the fund's investment objective and policies, subject to
the supervision of the fund's Trustees. Pioneer determines what portfolio
securities will be purchased or sold, arranges for the placing of orders for the
purchase or sale of portfolio securities, selects brokers or dealers to place
those orders, maintains books and records with respect to the fund's securities
transactions, and reports to the Trustees on the fund's investments and
performance.

Under the terms of its contract with the fund, Pioneer pays all the operating
expenses, including executive salaries and the rental of office space relating
to its services for the fund, with the exception of the following, which are
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 Pioneer, 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 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, state or
blue sky securities agencies 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 the 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 fund who are not affiliated with
or interested persons of Pioneer, the fund (other than as Trustees), PGI or PFD;
(k) the cost of preparing and printing share certificates; and (l) interest on
borrowed money, if any. In addition, 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. The Trustees' approval of and the
terms, continuance and termination of the management contract are governed by
the 1940 Act and the Investment Advisers Act of 1940, as applicable. Pursuant to
the management contract, Pioneer will not be liable for any error of judgment or
mistake of law or for any loss sustained by reason of the adoption of any
investment policy or the purchase, sale or retention of any securities on the
recommendation of Pioneer. Pioneer, however, is not protected against liability
by reason of willful misfeasance, bad faith or gross negligence in the
performance of its duties or by reason of its reckless disregard of its
obligations and duties under the management contract.

ADVISORY FEE. Effective May 1, 1996, as compensation for its management services
and expenses incurred, and certain expenses which Pioneer incurs on behalf of
the fund, the fund pays Pioneer a fee which varies with the fund's investment
performance compared to the Lipper Growth and Income Funds Index (the "Index").
The fee is 0.60% of the fund's average daily net assets (the "Basic Fee"),
subject to adjustment as provided below. An appropriate percentage of the Basic
Fee rate (based upon the number of days in the current month) is multiplied by
the fund's average daily net assets for the current month, giving a dollar
amount which is the monthly Basic Fee.

Prior to May 1, 1996, as compensation for its management services and expenses
incurred, Pioneer was entitled to a management fee at the annual rate of 0.50%
of the fund's average daily net assets up to $250 million, 0.48% of the next $50
million and 0.45% of the excess over $300 million. The fee was normally computed
daily and paid monthly.

PERFORMANCE FEE ADJUSTMENT. The Basic Fee is subject to an upward or downward
adjustment depending on whether and to what extent the investment performance of
the fund for the performance period exceeds, or is exceeded by, the record of
the Index over the same period. The Index represents the arithmetic mean
performance (i.e., equally weighted) of the 30 largest funds with investment
objectives oriented towards growth and income. The performance period consists
of the current month and the prior 35 months ("performance period"). Each
percentage point of difference (up to a maximum of +/-10) is multiplied by a
performance adjustment rate of 0.01%. The maximum annualized adjustment rate is
+/-0.10%. This performance comparison is made at the end of each month. An
appropriate percentage of this rate (based upon the number of days in the
current month) is then multiplied by the average daily net assets of the fund
over the entire performance period, giving a dollar amount that is added to (or
subtracted from) the Basic Fee. The monthly performance adjustment will be
further adjusted to the extent necessary in order to insure that the total
annual adjustment to the Basic Fee does not exceed +/-0.10% of the average daily
net assets for that year.

The fund's performance is calculated based on the net asset value of the fund's
Class A shares. For purposes of calculating the performance adjustment, any
dividends or capital gains distributions paid by the fund are treated as if
reinvested in Class A shares at the net asset value as of the payment date. The
record for the Index is based on change in value and is adjusted for any cash
distributions from the mutual funds comprising the Index.

APPLICATION OF PERFORMANCE ADJUSTMENT. The application of the performance
adjustment is illustrated by the following hypothetical example, assuming that
the net asset value of Class A shares of the fund and the level of the Index
were $10 and 100, respectively, on the first day of the performance period.

<TABLE>
<CAPTION>
                       INVESTMENT PERFORMANCE                       CUMULATIVE CHANGE
                  FIRST DAY         END OF PERIOD             ABSOLUTE     PERCENTAGE POINTS
<S>               <C>               <C>                       <C>          <C>
Fund                  $ 10                $ 13                   +$ 3             +30%
Index                  100                 123                   + 23             +23%
</TABLE>

The difference in relative performance for the performance period is +7
percentage points. Accordingly, the annualized management fee rate for the last
month of the performance period would be calculated as follows: An appropriate
percentage (based upon the number of days in the current month) of the Basic Fee
of 0.60% would be applied to the fund's average daily net assets for the month
resulting in a dollar amount. The +7 percentage point difference is multiplied
by the performance adjustment rate of 0.01% producing a rate of 0.07%. An
appropriate percentage of this rate (based upon the number of days in the
current month) is then applied to the average daily net assets of the fund over
the performance period resulting in a dollar amount which is added to the dollar
amount of the Basic Fee. The management fee paid is the dollar amount calculated
for the performance period. If the investment performance of the fund during the
performance period was exceeded by the record of the Index, the dollar amount of
performance adjustment would be deducted from the Basic Fee.

Because the adjustment to the Basic Fee is based on the comparative performance
of the fund and the record of the Index, the controlling factor is not whether
fund performance is up or down, but whether it is up or down more or less than
the record of the Index. Moreover, the comparative investment performance of the
fund is based solely on the relevant performance period without regard to the
cumulative performance over a longer or shorter period of time.

From time to time, the Trustees may determine that another securities index is a
more appropriate benchmark than the Index for purposes of evaluating the
performance of the fund. In such event, a successor index may be substituted for
the Index. However, the calculation of the performance adjustment for any
portion of the performance period prior to the adoption of the successor index
would still be based upon the fund's performance compared to the Index.

The fund's current management contract with Pioneer became effective May 1,
1996. Under the terms of the contract, beginning on May 1, 1996, the fund will
pay management fees at a rate equal to the Basic Fee plus or minus the amount of
the performance adjustment for the current month and the preceding 35 months. At
the end of each succeeding month, the performance period will roll forward one
month so that it is always a 36-month period consisting of the current month and
the prior 35 months as described above. If including the initial rolling
performance period (that is, the period prior to the effectiveness of the
management contract), has the effect of increasing the Basic Fee for any month,
such aggregate prior results will be treated as Index neutral for purposes of
calculating the performance adjustment for such month. Otherwise, the
performance adjustment will be made as described above.

The Basic Fee is computed daily, the performance fee adjustment is calculated
once per month and the entire management fee, allocated in proportion to the
average daily net assets for each class of shares, is normally paid monthly.

See the table in Appendix A for management fees paid to Pioneer during recently
completed fiscal years.

ADMINISTRATION AGREEMENT. The fund has entered into an administration agreement
with Pioneer pursuant to which certain accounting and legal services which are
expenses payable by the fund under the management contract are performed by
Pioneer and pursuant to which Pioneer is reimbursed for its costs of providing
such services.

POTENTIAL CONFLICT OF INTEREST. The fund is managed by Pioneer which also serves
as investment adviser to other Pioneer mutual funds and private accounts with
investment objectives identical or similar to those of the fund. Securities
frequently meet the investment objectives of the fund, the other Pioneer mutual
funds and such private accounts. In such cases, the decision to recommend a
purchase to one fund or account rather than another is based on a number of
factors. The determining factors in most cases are the amount of securities of
the issuer then outstanding, the value of those securities and the market for
them. Other factors considered in the investment recommendations include other
investments which each fund or account presently has in a particular industry
and the availability of investment funds in each fund or account.

It is possible that at times identical securities will be held by more than one
fund and/or account. However, positions in the same issue may vary and the
length of time that any fund or account may choose to hold its investment in the
same issue may likewise vary. To the extent that more than one of the Pioneer
mutual funds or a private account managed by Pioneer seeks to acquire the same
security at about the same time, the fund may not be able to acquire as large a
position in such security as it desires or it may have to pay a higher price for
the security. Similarly, the fund may not be able to obtain as large an
execution of an order to sell or as high a price for any particular portfolio
security if Pioneer decides to sell on behalf of another fund or account the
same portfolio security at the same time. On the other hand, if the same
securities are bought or sold at the same time by more than one fund or account,
the resulting participation in volume transactions could produce better
executions for the fund. In the event more than one account purchases or sells
the same security on a given date, the purchases and sales will normally be made
as nearly as practicable on a pro rata basis in proportion to the amounts
desired to be purchased or sold by each account. Although the other Pioneer
mutual funds may have the same or similar investment objectives and policies as
the fund, their portfolios do not generally consist of the same investments as
the fund or each other, and their performance results are likely to differ from
those of the fund.

PERSONAL SECURITIES TRANSACTIONS. In an effort to avoid conflicts of interest
with the fund, the fund and Pioneer have adopted a code of ethics that is
designed to maintain a high standard of personal conduct by directing that all
personnel defer to the interests of the fund and its shareholders in making
personal securities transactions.

5.   PRINCIPAL UNDERWRITER AND DISTRIBUTION PLANS

PRINCIPAL UNDERWRITER

PFD, 60 State Street, Boston, Massachusetts 02109, is the principal underwriter
for the fund in connection with the continuous offering of its shares. PFD is an
indirect wholly owned subsidiary of PGI.

The fund entered into an underwriting agreement with PFD which provides that PFD
will bear expenses for the distribution of the fund's shares, except for
expenses incurred by PFD for which it is reimbursed or compensated by the fund
under the distribution plans (discussed below). PFD bears all expenses it incurs
in providing services under the underwriting agreement. Such expenses include
compensation to its employees and representatives and to securities dealers for
distribution-related services performed for the fund. PFD also pays certain
expenses in connection with the distribution of the fund's shares, including the
cost of preparing, printing and distributing advertising or promotional
materials, and the cost of printing and distributing prospectuses and
supplements to prospective shareholders. The fund bears the cost of registering
its shares under federal and state securities law and the laws of certain
foreign countries. Under the underwriting agreement, PFD will use its best
efforts in rendering services to the fund.

See "Class A Share Sales Charges" for the schedule of initial sales charge
reallowed to dealers as a percentage of the offering price of the fund's Class A
shares.

See the tables in Appendix A for commissions retained by PFD and reallowed to
dealers in connection with PFD's offering of the fund's Class A shares during
recently completed fiscal years.

The fund will not generally issue fund shares for consideration other than cash.
At the fund's sole discretion, however, it may issue fund shares for
consideration other than cash in connection with a bona fide reorganization,
statutory merger or other acquisition of portfolio securities.

DISTRIBUTION PLANS

The fund has adopted a plan of distribution pursuant to Rule 12b-1 under the
1940 Act with respect to its Class A shares (the "Class A Plan"), a plan of
distribution with respect to its Class B shares (the "Class B Plan") and a plan
of distribution with respect to its Class C shares (the "Class C Plan")
(together, the "Plans"), pursuant to which certain distribution and service fees
are paid to PFD. The fund has not adopted a plan of distribution with respect to
its Class Y shares. Because of the Plans, long-term shareholders may pay more
than the economic equivalent of the maximum sales charge permitted by the
National Association of Securities Dealers, Inc. (the "NASD") regarding
investment companies.

CLASS A PLAN. 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 Board of Trustees. The Board of Trustees has approved the following
categories of expenses that may be reimbursed under the Class A Plan: (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; 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 is
prohibited from acting in any capacity or providing any of the described
services, management will consider what action, if any, would be appropriate.
The expenses of the fund pursuant to the Class A Plan are accrued daily at a
rate which may not exceed the annual rate of 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 does not provide for the carryover of reimbursable expenses
beyond 12 months from the time the fund is first invoiced for an expense. The
limited carryover provision in the Class A Plan may result in an expense
invoiced to the fund in one fiscal year being paid in the subsequent fiscal year
and thus being treated for purposes of calculating the maximum expenditures of
the fund as having been incurred in the subsequent fiscal year. In the event of
termination or non-continuance of the Class A Plan, the fund has 12 months to
reimburse any expense which it incurs prior to such termination or
non-continuance, provided that payments by the fund during such 12-month period
shall not exceed 0.25% of the fund's average daily net assets attributable to
Class A shares during such period. See Appendix A for the amount, if any, of
carryover of distribution expenses as of the end of the most recent calendar
year.

CLASS B PLAN. Commissions on the sale of Class B shares equal to 3.75% of the
amount invested are paid to broker-dealers who have sales agreements with PFD.
PFD may also advance to dealers the first-year service fee payable under the
Class B Plan at a rate up to 0.25% of the purchase price of such shares. As
compensation for such advance of the service fee, PFD may retain the service fee
paid by the fund with respect to such shares for the first year after purchase.

The Class B Plan provides that the fund shall pay PFD, as the fund's distributor
for its Class B shares, a daily distribution fee equal on an annual basis to
0.75% of the fund's average daily net assets attributable to Class B shares and
will pay PFD a service fee equal to 0.25% of the fund's average daily net assets
attributable to Class B shares (which PFD will in turn pay to securities dealers
which enter into a sales agreement with PFD at a rate of up to 0.25% of the
fund's average daily net assets attributable to Class B shares owned by
investors for whom that securities dealer is the holder or dealer of record).
This service fee is intended to be in consideration of personal services and/or
account maintenance services rendered by the dealer with respect to Class B
shares. Commencing in the 13th month following the purchase of Class B shares,
dealers will become eligible for additional annual service fees of up to 0.25%
of the net asset value of such shares. Dealers may from time to time be required
to meet certain other 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.

The purpose of distribution payments to PFD under the Class B Plan is to
compensate PFD for its distribution services with respect to Class B shares of
the fund. PFD pays commissions to dealers as well as expenses of printing
prospectuses and reports used for sales purposes, expenses with respect to the
preparation and printing of sales literature and other distribution-related
expenses, including, without limitation, the cost necessary to provide
distribution-related services, or personnel, travel, office expenses and
equipment. The Class B Plan also provides that PFD will receive all contingent
deferred sales charges ("CDSCs") attributable to Class B shares. When a
broker-dealer sells Class B shares and elects, with PFD's approval, to waive its
right to receive the commission normally paid at the time of the sale, PFD may
cause all or a portion of the distribution fees described above to be paid to
the broker-dealer.

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

     (i)     to the extent required by a change in the 1940 Act, the rules or
             regulations under the 1940 Act, the Conduct Rules of the NASD or an
             order of any court or governmental agency, in each case enacted,
             issued or promulgated after September 30, 1998;

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

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

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

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

CLASS C PLAN. Commissions on the sale of Class C shares of up to 0.75% of the
amount invested in Class C shares are paid to broker-dealers who have sales
agreements with PFD. PFD may also advance to dealers the first-year service fee
payable under the Class C Plan at a rate up to 0.25% of the purchase price of
such shares. As compensation for such advance of the service fee, PFD may retain
the service fee paid by the fund with respect to such shares for the first year
after purchase.

The Class C Plan provides that the fund will pay PFD, as the fund's distributor
for its Class C shares, a distribution fee accrued daily and paid quarterly,
equal on an annual basis to 0.75% of the fund's average daily net assets
attributable to Class C shares and will pay PFD a service fee equal to 0.25% of
the fund's average daily net assets attributable to Class C shares. PFD will in
turn pay to securities dealers which enter into a sales agreement with PFD a
distribution fee and a service fee at rates of up to 0.75% and 0.25%,
respectively, of the fund's average daily net assets attributable to Class C
shares owned by investors for whom that securities dealer is the holder or
dealer of record. The service fee is intended to be in consideration of personal
services and/or account maintenance services rendered by the dealer with respect
to Class C shares. PFD will advance to dealers the first-year service fee at a
rate equal to 0.25% of the amount invested. As compensation therefor, PFD may
retain the service fee paid by the fund with respect to such shares for the
first year after purchase. Commencing in the 13th month following the purchase
of Class C shares, dealers will become eligible for additional annual
distribution fees and service fees of up to 0.75% and 0.25%, respectively, of
the net asset value of such shares. Dealers may from time to time be required to
meet certain other criteria in order to receive service fees. PFD or its
affiliates are entitled to retain all service fees payable under the Class C
Plan for which there is no dealer of record or for which qualification standards
have not been met as partial consideration for personal services and/or account
maintenance services performed by PFD or its affiliates for shareholder
accounts.

The purpose of distribution payments to PFD under the Class C Plan is to
compensate PFD for its distribution services with respect to Class C shares of
the fund. PFD pays commissions to dealers as well as expenses of printing
prospectuses and reports used for sales purposes, expenses with respect to the
preparation and printing of sales literature and other distribution-related
expenses, including, without limitation, the cost necessary to provide
distribution-related services, or personnel, travel, office expenses and
equipment. The Class C Plan also provides that PFD will receive all CDSCs
attributable to Class C shares. When a broker-dealer sells Class C shares and
elects, with PFD's approval, to waive its right to receive the commission
normally paid at the time of the sale, PFD may cause all or a portion of the
distribution fees described above to be paid to the broker-dealer.

GENERAL

In accordance with the terms of each Plan, PFD provides to the fund for review
by the Trustees a quarterly written report of the amounts expended under the
Plan and the purposes for which such expenditures were made. In the Trustees'
quarterly review of the Plans, they will consider the continued appropriateness
and the level of reimbursement or compensation the Plans provide.

No interested person of the fund, nor any Trustee of the fund who is not an
interested person of the fund, has any direct or indirect financial interest in
the operation of the Plans except to the extent that PFD and certain of its
employees may be deemed to have such an interest as a result of receiving a
portion of the amounts expended under the Plans by the fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.

Each Plan's adoption, terms, continuance and termination are governed by Rule
12b-1 under the 1940 Act. The Board of Trustees believes that there is a
reasonable likelihood that the Plans will benefit the fund and its current and
future shareholders. The Plans 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
affected thereby, and material amendments of the Plans must also be approved by
the Trustees as provided in Rule 12b-1.

See Appendix A for fund expenses under the Class A Plan, Class B Plan and Class
C Plan and CDSCs paid to PFD for the most recently completed fiscal year.

Upon redemption, Class A shares may be subject to a 1% CDSC, Class B shares are
subject to a CDSC at a rate declining from a maximum 4% of the lower of the cost
or market value of the shares and Class C shares may be subject to a 1% CDSC.

6.   SHAREHOLDER SERVICING/TRANSFER AGENT

The fund has contracted with PSC, 60 State Street, Boston, Massachusetts 02109,
to act as shareholder servicing and transfer agent for the fund.

Under the terms of its contract with the fund, PSC services shareholder
accounts, and its duties include: (i) processing sales, redemptions and
exchanges of shares of the fund; (ii) distributing dividends and capital gains
associated with the fund's portfolio; and (iii) maintaining account records and
responding to shareholder inquiries.

PSC receives an annual fee of $22.75 for each Class A, Class B, Class C [and
Class Y] shareholder account from the fund as compensation for the services
described above. PSC is also reimbursed by the fund for its cash out-of-pocket
expenditures. The fund may compensate entities which have agreed to provide
certain sub-accounting services such as specific transaction processing and
recordkeeping services. Any such payments by the fund would be in lieu of the
per account fee which would otherwise be paid by the fund to PSC.

7.   CUSTODIAN

Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts 02109, is
the custodian of the fund's assets. The custodian's responsibilities include
safekeeping and controlling the fund's cash and securities, handling the receipt
and delivery of securities, and collecting interest and dividends on the fund's
investments.

8.   INDEPENDENT PUBLIC ACCOUNTANTS

Arthur Andersen LLP, 225 Franklin Street, Boston, Massachusetts 02110, is the
fund's independent public accountants, providing audit services, tax return
review, and assistance and consultation with respect to the preparation of
filings with the SEC.

9.   PORTFOLIO TRANSACTIONS

All orders for the purchase or sale of portfolio securities are placed on behalf
of the fund by Pioneer pursuant to authority contained in the fund's management
contract. Pioneer seeks to obtain the best execution on portfolio trades. The
price of securities and any commission rate paid are always factors, but
frequently not the only factors, in judging best execution. In selecting brokers
or dealers, Pioneer considers various relevant factors, including, but not
limited to, the size and type of the transaction; the nature and character of
the markets for the security to be purchased or sold; the execution efficiency,
settlement capability and financial condition of the dealer; the dealer's
execution services rendered on a continuing basis; and the reasonableness of any
dealer spreads. Transactions in foreign equity securities are executed by
broker-dealers in foreign countries in which commission rates are fixed and,
therefore, are not negotiable (as such rates are in the U.S.).

Pioneer may select broker-dealers that provide brokerage and/or research
services to the fund and/or other investment companies or other accounts managed
by Pioneer. In addition, consistent with Section 28(e) of the Securities
Exchange Act of 1934, as amended, if Pioneer determines in good faith that the
amount of commissions charged by a broker-dealer is reasonable in relation to
the value of the brokerage and research services provided by such broker, the
fund may pay commissions to such broker-dealer in an amount greater than the
amount another firm may charge. Such services may include advice concerning the
value of securities; the advisability of investing in, purchasing or selling
securities; the availability of securities or the purchasers or sellers of
securities; providing stock quotation services, credit rating service
information and comparative fund statistics; furnishing analyses, electronic
information services, manuals and reports concerning issuers, industries,
securities, economic factors and trends, portfolio strategy, and performance of
accounts and particular investment decisions; and effecting securities
transactions and performing functions incidental thereto (such as clearance and
settlement). Pioneer maintains a listing of broker-dealers who provide such
services on a regular basis. However, because many transactions on behalf of the
fund and other investment companies or accounts managed by Pioneer are placed
with broker-dealers (including broker-dealers on the listing) without regard to
the furnishing of such services, it is not possible to estimate the proportion
of such transactions directed to such dealers solely because such services were
provided. Pioneer believes that no exact dollar value can be calculated for such
services.

The research received from broker-dealers may be useful to Pioneer in rendering
investment management services to the fund as well as other investment companies
or other accounts managed by Pioneer, although not all such research may be
useful to the fund. Conversely, such information provided by brokers or dealers
who have executed transaction orders on behalf of such other accounts may be
useful to Pioneer in carrying out its obligations to the fund. The receipt of
such research has not reduced Pioneer's normal independent research activities;
however, it enables Pioneer to avoid the additional expenses which might
otherwise be incurred if it were to attempt to develop comparable information
through its own staff.

In circumstances where two or more broker-dealers offer comparable prices and
executions, preference may be given to a broker-dealer which has sold shares of
the fund as well as shares of other investment companies managed by Pioneer.
This policy does not imply a commitment to execute all portfolio transactions
through all broker-dealers that sell shares of the fund.

Pursuant to certain directed brokerage arrangements with third-party broker
dealers, such broker-dealers may pay certain of the fund's custody expenses. The
fund has also entered into expense offset arrangements resulting in further
reduction in the fund's total expenses. See "Financial highlights" in the
prospectus.

See the table in Appendix A for aggregate brokerage and underwriting commissions
paid by the fund in connection with its portfolio transactions during recently
completed fiscal years. The Board of Trustees periodically reviews Pioneer's
performance of its responsibilities in connection with the placement of
portfolio transactions on behalf of the fund.

10.  DESCRIPTION OF SHARES

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 next determined net asset value per share less
any applicable CDSC. See "Sales Charges." When issued and paid for in accordance
with the terms of the prospectus and statement of additional information, shares
of the fund are fully paid and non-assessable. Shares will remain on deposit
with the fund's transfer agent and certificates will not normally be issued. The
fund reserves the right to charge a fee for the issuance of Class A share
certificates; certificates will not be issued for Class B, Class C or Class Y
shares.

The fund's Agreement and Declaration of Trust, dated April 26, 1996 (the
"Declaration"), permits the Board of Trustees to authorize the issuance of an
unlimited number of full and fractional shares of beneficial interest which may
be divided into such separate series as the Trustees may establish. Currently,
the fund consists of only one series. The Trustees may, however, establish
additional series of shares and may divide or combine the shares into a greater
or lesser number of shares without thereby changing the proportionate beneficial
interests in the fund. The Declaration further authorizes the Trustees to
classify or reclassify any series of the shares into one or more classes.
Pursuant thereto, the Trustees have authorized the issuance of four classes of
shares of the fund, designated as Class A shares, Class B shares, Class C shares
and Class Y shares. Each share of a class of the fund represents an equal
proportionate interest in the assets of the fund allocable to that class. Upon
liquidation of the fund, shareholders of each class of the fund are entitled to
share pro rata in the fund's net assets allocable to such class available for
distribution to shareholders. The fund reserves the right to create and issue
additional series or classes of shares, in which case the shares of each class
of a series would participate equally in the earnings, dividends and assets
allocable to that class of the particular series.

The shares of each class represent an interest in the same portfolio of
investments of the fund. Each class has equal rights as to voting, redemption,
dividends and liquidation, except that each class bears different distribution
and transfer agent fees and may bear other expenses properly attributable to the
particular class. Class A, Class B and Class C shareholders have exclusive
voting rights with respect to the Rule 12b-1 Plans adopted by holders of those
shares in connection with the distribution of shares.

Shareholders are entitled to one vote for each share held and may vote in the
election of Trustees and on other matters submitted to a meeting of
shareholders. Although Trustees are not elected annually by the shareholders,
shareholders have, under certain circumstances, the right to remove one or more
Trustees. 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 shares of each series of the fund are entitled to vote separately to approve
investment advisory agreements or changes in investment restrictions, but
shareholders of all series vote together in the election and selection of
Trustees and accountants. Shares of all series of the fund vote together as a
class on matters that affect all series of the fund in substantially the same
manner. As to matters affecting a single series or class, shares of such series
or class will vote separately. No amendment adversely affecting the rights of
shareholders may be made to the Declaration without the affirmative vote of a
majority of the fund's shares. Shares have no preemptive or conversion rights
except that under certain circumstances Class B shares may convert to Class A
shares.

As a Delaware business trust, the fund's operations are governed by the
Declaration. Generally, Delaware business trust shareholders are not personally
liable for obligations of the Delaware business trust under Delaware law. The
Delaware Business Trust Act (the "Delaware Act") provides that a shareholder of
a Delaware business trust shall be entitled to the same limitation of liability
extended to shareholders of private for-profit corporations. The Declaration
expressly provides that the fund is organized under the Delaware Act and that
the Declaration is to be governed by Delaware law. There is nevertheless a
possibility that a Delaware business trust, such as the fund, might become a
party to an action in another state whose courts refused to apply Delaware law,
in which case the fund's shareholders could become subject to personal
liability.

To guard against this risk, the Declaration (i) contains an express disclaimer
of shareholder liability for acts or obligations of the fund and provides that
notice of such disclaimer may be given in each agreement, obligation or
instrument entered into or executed by the fund or its Trustees, (ii) provides
for the indemnification out of fund property of any shareholders held personally
liable for any obligations of the fund or any series of the fund and (iii)
provides that the fund shall, upon request, assume the defense of any claim made
against any shareholder for any act or obligation of the fund and satisfy any
judgment thereon. Thus, the risk of a shareholder incurring financial loss
beyond his or her investment because of shareholder liability is limited to
circumstances in which all of the following factors are present: (1) a court
refused to apply Delaware law; (2) the liability arose under tort law or, if
not, no contractual limitation of liability was in effect; and (3) the fund
itself would be unable to meet its obligations. In light of Delaware law, the
nature of the fund's business and the nature of its assets, the risk of personal
liability to a fund shareholder is remote.

In addition to the requirements under Delaware law, the Declaration 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.

The Declaration further provides that the fund shall indemnify each of its
Trustees and officers against liabilities and expenses reasonably incurred by
them in connection with, or arising out of, any action, suit or proceeding,
threatened against or otherwise involving such Trustee or officer, directly or
indirectly, by reason of being or having been a Trustee or officer of the fund.
The Declaration does not authorize the fund to indemnify any Trustee or officer
against any liability to which he or she would otherwise be subject by reason of
or for willful misfeasance, bad faith, gross negligence or reckless disregard of
such person's duties.

The Declaration provides that any Trustee who is not an "interested person" of
Pioneer shall be considered to be independent for purposes of Delaware law
notwithstanding the fact that such Trustees receive compensation for serving as
a Trustee of the fund or other investment companies for which Pioneer acts as
investment adviser.

11.  SALES CHARGES

The fund continuously offers four classes of shares designated as Class A, Class
B, Class C and Class Y shares as described in the prospectus.

CLASS A SHARE SALES CHARGES

You may buy Class A shares at the public offering price, including a sales
charge, as follows:

<TABLE>
<CAPTION>
                                            SALES CHARGE AS A % OF
                                            OFFERING          NET AMOUNT        DEALER

Less than $50,000                           5.75              6.10              5.00
$50,000 but less than $100,000              4.50              4.71              4.00
$100,000 but less than $250,000             3.50              3.63              3.00
$250,000 but less than $500,000             2.50              2.56              2.00
$500,000 but less than $1,000,000           2.00              2.04              1.75
$1,000,000 or more                          0.00              0.00              see below
</TABLE>

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 Sections 401 or
408 of the Code although more than one beneficiary is involved. The sales
charges applicable to a current purchase of Class A shares of the fund by a
person listed above is determined by adding the value of shares to be purchased
to the aggregate value (at the then current offering price) of shares of any of
the other Pioneer mutual funds previously purchased and then owned, provided PFD
is notified by such person or his or her broker-dealer each time a purchase is
made which would qualify. Pioneer mutual funds include all mutual funds for
which PFD serves as principal underwriter. At the sole discretion of PFD,
holdings of funds domiciled outside the U.S., but which are managed by
affiliates of Pioneer, may be included for this purpose.

No sales charge is payable at the time of purchase on investments of $1 million
or more, or for purchases by participants in certain group plans described below
subject to a CDSC of 1% which may be imposed in the event of a redemption of
Class A shares within 12 months of purchase. PFD may, in its discretion, pay a
commission to broker-dealers who initiate and are responsible for such purchases
as follows: 1% on the first $5 million invested; 0.50% on the next $45 million
invested; and 0.25% on the excess over $50 million invested. These commissions
shall not be payable 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 commissions paid or a pro
rata portion thereof if the retirement plan redeems its shares within 12 months
of purchase. Contingent upon the achievement of certain sales objectives, PFD
may pay to Mutual of Omaha Investor Services, Inc. [50%] of PFD's retention of
any sales commission on sales of the fund's Class A shares through such dealer.
From time to time, PFD may elect to reallow the entire initial sales charge to
participating dealers for all Class A sales with respect to which orders are
placed during a particular period. Dealers to whom substantially the entire
sales charge is reallowed may be deemed to be underwriters under the federal
securities laws.

LETTER OF INTENT ("LOI"). Reduced sales charges are available for purchases of
$50,000 or more of Class A shares (excluding any reinvestments of dividends and
capital gains distributions) made within a 13-month period pursuant to an LOI
which may be established by completing the Letter of Intent section of the
Account Application. The reduced sales charge will be the charge that would be
applicable to the purchase of the specified amount of Class A shares as if the
shares had all been purchased at the same time. A purchase not made pursuant to
an LOI may be included if the LOI is submitted to PSC within 90 days of such
purchase. You may also obtain the reduced sales charge by including the value
(at current offering price) of all your Class A shares in the fund and all other
Pioneer mutual funds held of record as of the date of your LOI in the amount
used to determine the applicable sales charge for the Class A shares to be
purchased under the LOI. Five percent of your total intended purchase amount
will be held in escrow by PSC, registered in your name, until the terms of the
LOI are fulfilled. When you sign the Account Application, you agree to
irrevocably appoint PSC your attorney-in-fact to surrender for redemption any or
all shares held in escrow with full power of substitution. An LOI is not a
binding obligation upon the investor to purchase, or the fund to sell, the
amount specified in the LOI.

If the total purchases, less redemptions, exceed the amount specified under the
LOI and are in an amount which would qualify for a further quantity discount,
all transactions will be recomputed on the expiration date of the LOI to effect
the lower sales charge. Any difference in the sales charge resulting from such
recomputation will be either delivered to you in cash or invested in additional
shares at the lower sales charge. The dealer, by signing the Account
Application, agrees to return to PFD, as part of such retroactive adjustment,
the excess of the commission previously reallowed or paid to the dealer over
that which is applicable to the actual amount of the total purchases under the
LOI.

If the total purchases, less redemptions, are less than the amount specified
under the LOI, you must remit to PFD any difference between the sales charge on
the amount actually purchased and the amount originally specified in the LOI.
When the difference is paid, the shares held in escrow will be deposited to your
account. If you do not pay the difference in sales charge within 20 days after
written request from PFD or your dealer, PSC, after receiving instructions from
PFD, will redeem the appropriate number of shares held in escrow to realize the
difference and release any excess.

CLASS B SHARES

You may buy Class B shares at the net asset value per share next computed after
receipt of a purchase order without the imposition of an initial sales charge;
however, Class B shares redeemed within six years of purchase will be subject to
a 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 after
September 30, 1998, all payments during a month will be aggregated and deemed to
have been made on the first day of that month. For the purpose of determining
the number of years from the time of any purchase made prior to October 1, 1998,
all payments during a quarter will be aggregated and deemed to have been made on
the first day of that quarter. In processing redemptions of Class B shares, the
fund will first redeem shares not subject to any CDSC and then shares held
longest during the six-year period. As a result, you will pay the lowest
possible CDSC.

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

<TABLE>
<CAPTION>
                                                     CDSC AS A % OF DOLLAR
         YEAR SINCE PURCHASE                         AMOUNT SUBJECT TO CDSC

         Fourth                                               3.0
         Fifth                                                2.0
         Sixth                                                1.0
         Seventh and thereafter                               0.0
</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 beginning
of the calendar month (or the calendar quarter for purchases made prior to
October 1, 1998) that is eight years after the purchase date, except as noted
below. Class B shares acquired by exchange from Class B shares of another
Pioneer mutual fund will convert into Class A shares based on the date of the
initial purchase and the applicable CDSC. Class B shares acquired through
reinvestment of distributions will convert into Class A shares based on the date
of the initial purchase to which such shares relate. For this purpose, Class B
shares acquired through reinvestment of distributions will be attributed to
particular purchases of Class B shares in accordance with such procedures as the
Trustees may determine from time to time. The conversion of Class B shares to
Class A shares is subject to the continuing availability of a ruling from the
Internal Revenue Service (the "IRS") or an opinion of counsel that such
conversions will not constitute taxable events for federal tax purposes. The
conversion of Class B shares to Class A shares will not occur if such ruling or
opinion is not available and, therefore, Class B shares would continue to be
subject to higher expenses than Class A shares for an indeterminate period.

CLASS C SHARES

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

For the purpose of determining the time of any purchase after September 30,
1998, all payments during a month will be aggregated and deemed to have been
made on the first day of that month. For the purpose of determining the time of
any purchase made prior to October 1, 1998, all payments during a calendar
quarter will be aggregated and deemed to have been made on the first day of that
quarter. In processing redemptions of Class C shares, the fund will first redeem
shares not subject to any CDSC and then shares held for the shortest period of
time during the one-year period. As a result, you will pay the lowest possible
CDSC.

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

12.      REDEEMING SHARES

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 for shareholders that are
subject to U.S. federal income tax. 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.

SYSTEMATIC WITHDRAWAL PLAN(S) ("SWP") (CLASS A, CLASS B AND CLASS C SHARES). A
SWP is designed to provide a convenient method of receiving fixed payments at
regular intervals from fund share accounts having a total value of not less than
$10,000. You must also be reinvesting all dividends and capital gains
distributions to use the SWP option.

Periodic payments of $50 or more will be deposited monthly, quarterly,
semiannually or annually directly into a bank account designated by the
applicant or will be sent by check to the applicant, or any person designated by
the applicant. Payments can be made either by check or electronic funds transfer
to a bank account designated by you. Class B accounts must meet the minimum
initial investment requirement prior to establishing a SWP. Withdrawals from
Class B and Class C share accounts are limited to 10% of the value of the
account at the time the SWP is established. See "Qualifying for a reduced sales
charge" in the prospectus. If you direct that withdrawal payments be paid to
another person, want to change the bank where payments are sent or designate an
address that is different from the account's address of record after you have
opened your account, a signature guarantee must accompany your instructions.
Withdrawals under the SWP are redemptions that may have tax consequences for
you.

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. SWP redemptions reduce and may ultimately exhaust the number of
shares in your account. In addition, the amounts received by a shareholder
cannot be considered as yield or income on his or her investment because part of
such payments may be a return of his or her investment. Withdrawals under the
SWP are redemptions that may have tax consequences for you.

A SWP may be terminated at any time (1) by written notice to PSC or from PSC to
the shareholder; (2) upon receipt by PSC of appropriate evidence of the
shareholder's death; or (3) when all shares in the shareholder's account have
been redeemed.

You may obtain additional information by calling PSC at 1-800-225-6292.

REINSTATEMENT PRIVILEGE (CLASS A SHARES). 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 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. For example, if a redemption resulted in a loss and an investment is
made in shares of the fund within 30 days before or after the redemption, you
may not be able to recognize the loss for federal income tax purposes. Subject
to the provisions outlined in the prospectus, 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.

13.      TELEPHONE TRANSACTIONS

You may purchase, exchange or sell Class A, Class B or Class C shares by
telephone. Class Y shares may not be purchased by telephone. See the prospectus
for more information. For personal assistance, call 1-800-225-6292 between 8:00
a.m. and 9:00 p.m. (Class Y account holders should contact Pioneer's Group Plans
Department at 1-888-294-4480 between 9:00 a.m. and 6:00 p.m.) Eastern time on
weekdays. Computer-assisted transactions may be available to shareholders who
have prerecorded certain bank information (see "FactFoneSM"). YOU ARE STRONGLY
URGED TO CONSULT WITH YOUR INVESTMENT PROFESSIONAL PRIOR TO REQUESTING ANY
TELEPHONE TRANSACTION.

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 nor PFD will be responsible for
the authenticity of instructions received by telephone; therefore, you bear the
risk of loss for unauthorized or fraudulent telephone transactions.

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

FACTFONESM. FactFoneSM is an automated inquiry and telephone transaction system
available to Pioneer mutual fund shareholders by dialing 1-800-225-4321.
FactFoneSM allows shareholder access to current information on Pioneer mutual
fund accounts and to the prices and yields of all publicly available Pioneer
mutual funds. In addition, you may use FactFoneSM to make computer-assisted
telephone purchases, exchanges or redemptions from your Pioneer mutual fund
accounts, access your account balances and last three transactions and order a
duplicate statement if you have activated your PIN. Telephone purchases or
redemptions require the establishment of a bank account of record.
Computer-assisted Class Y share telephone purchases, exchanges and redemptions
and certain other FactFoneSM features for Class Y shareholders are not currently
available through FactFoneSM. YOU ARE STRONGLY URGED TO CONSULT WITH YOUR
INVESTMENT PROFESSIONAL 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 FactFoneSM. Call PSC for assistance.

FactFoneSM allows shareholders to hear the following recorded fund information:

o    net asset value prices for all Pioneer mutual funds;

o    annualized 30-day yields on Pioneer's fixed income funds;

o    annualized 7-day yields and 7-day effective (compound) yields for Pioneer's
     money market fund; and

o    dividends and capital gains distributions on all Pioneer mutual funds.

Yields are calculated in accordance with SEC mandated standard formulas.

All performance numbers communicated through FactFoneSM represent past
performance, and figures include the maximum applicable sales charge. A
shareholder's actual yield and total return will vary with changing market
conditions. The value of Class A, Class B, Class C and Class Y shares (except
for Pioneer Cash Reserves Fund, which seeks to maintain a stable $1.00 share
price) will also vary, and such shares may be worth more or less at redemption
than their original cost.

14.      PRICING OF SHARES

The net asset value per share of each class of the fund is determined as of the
close of regular trading on the Exchange (normally 4:00 p.m. Eastern time) on
each day on which the Exchange is open for trading. As of the date of this
statement of additional information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day. The net asset value per share of each
class of the fund is also determined on any other day on which the level of
trading in its portfolio securities is sufficiently high that the current net
asset value per share might be materially affected by changes in the value of
its portfolio securities. The fund is not required to determine its net asset
value per share on any day on which no purchase orders in good order for fund
shares are received and no shares are tendered and accepted for redemption.

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 may be 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, although the actual
computations may be made by persons acting pursuant to the direction of the
Board of Trustees.

The net asset value per share of each class of the fund is computed by taking
the value of all of the fund's assets attributable to a class, less the fund's
liabilities attributable to that class, and dividing the result by the number of
outstanding shares of that class. For purposes of determining net asset value,
expenses of the classes of the fund are accrued daily and taken into account.
The fund's maximum offering price per Class A share is determined by adding the
maximum sales charge to the net asset value per Class A share. Class B, Class C
and Class Y shares are offered at net asset value without the imposition of an
initial sales charge (Class B and Class C shares may be subject to a CDSC).

15.      TAX STATUS

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 tax on income and capital gains distributed to
shareholders as required under the Code. If the fund did not qualify as a
regulated investment company, it would be treated as a U.S. corporation subject
to federal income tax. Under the Code, the fund will be subject to a
nondeductible 4% federal excise tax on a portion of its undistributed ordinary
income and capital gains if it fails to meet certain distribution requirements
with respect to each calendar year. The fund intends to make distributions in a
timely manner and accordingly does not expect to be subject to the excise tax.

The fund generally pays distributions of net long-term capital gains in
November. The fund generally pays dividends from any net investment income or
distributions of net short-term capital gains quarterly during March, June,
September and in December. Dividends from income and/or capital gains may also
be paid at such other times as may be necessary for the fund to avoid federal
income or excise tax.

In order to qualify as a regulated investment company under Subchapter M, the
fund must, among other things, derive at least 90% of its gross income for each
taxable year from dividends, interest, payments with respect to securities
loans, gains from the sale or other disposition of stock, securities or foreign
currencies, or other income (including gains from options, futures and forward
contracts) derived with respect to its business of investing in such stock,
securities or currencies (the "90% income test") and satisfy certain annual
distribution and quarterly diversification requirements. For purposes of the 90%
income test, income the fund earns from equity interests in certain entities
that are not treated as corporations (e.g., are treated as partnerships or
trusts) for U.S. tax purposes will generally have the same character for the
fund as in the hands of such entities. Consequently, the fund may be required to
limit its equity investments in such entities that earn fee income, rental
income or other nonqualifying income.

Unless shareholders specify otherwise, all distributions will be automatically
reinvested in additional full and fractional shares of the fund. For federal
income tax purposes, all dividends are taxable as described below whether a
shareholder takes them in cash or reinvests them in additional shares of the
fund. Dividends from investment company taxable income, which includes net
investment income, net short-term capital gain in excess of net long-term
capital loss and certain net foreign exchange gains, are taxable as ordinary
income. Dividends from net long-term capital gain in excess of net short-term
capital loss ("net capital gain"), if any, are taxable to the fund's
shareholders as long-term capital gains for federal income tax purposes without
regard to the length of time shares of the fund have been held. The federal
income tax status of all distributions will be reported to shareholders
annually.

Any dividend declared by the fund in October, November or December as of a
record date in such a month and paid during the following January will be
treated for federal income tax purposes as received by shareholders on December
31 of the calendar year in which it is declared.

Foreign exchange gains and losses realized by the fund in connection with
certain transactions involving foreign currency-denominated debt securities,
certain options and futures contracts relating to foreign currency, foreign
currency forward contracts, foreign currencies, or payables or receivables
denominated in a foreign currency are subject to Section 988 of the Code, which
generally causes such gains and losses to be treated as ordinary income and
losses and may affect the amount, timing and character of distributions to
shareholders. Under future regulations, any such transactions that are not
directly related to the fund's investments in stock or securities (or its
options contracts or futures contracts with respect to stock or securities) may
need to be limited in order to enable the fund to satisfy the 90% income test.
If the net foreign exchange loss for a year were to exceed the fund's investment
company taxable income (computed without regard to such loss), the resulting
ordinary loss for such year would not be deductible by the fund or its
shareholders in future years.

If the fund acquires any equity interest (under proposed regulations, generally
including not only stock but also an option to acquire stock such as is inherent
in a convertible bond) in certain foreign corporations that receive at least 75%
of their annual gross income from passive sources (such as interest, dividends,
certain rents and royalties, or capital gains) or hold at least 50% of their
assets in investments producing such passive income ("passive foreign investment
companies"), the fund could be subject to federal income tax and additional
interest charges on "excess distributions" received from such companies or gain
from the sale of stock in such companies, even if all income or gain actually
received by the fund is timely distributed to its shareholders. The fund would
not be able to pass through to its shareholders any credit or deduction for such
a tax. An election may generally be available that would ameliorate these
adverse tax consequences, but any such election could require the fund to
recognize taxable income or gain (subject to tax distribution requirements)
without the concurrent receipt of cash. These investments could also result in
the treatment of associated capital gains as ordinary income. The fund may limit
and/or manage its holdings in passive foreign investment companies to limit its
tax liability or maximize its return from these investments.

The fund may invest to a limited extent in debt obligations that are in the
lowest rating categories or are unrated, including debt obligations of issuers
not currently paying interest or who are in default. Investments in debt
obligations that are at risk of or in default present special tax issues for the
fund. Tax rules are not entirely clear about issues such as when the fund may
cease to accrue interest, original issue discount or market discount, when and
to what extent deductions may be taken for bad debts or worthless securities,
how payments received on obligations in default should be allocated between
principal and income and whether exchanges of debt obligations in a workout
context are taxable. These and other issues will be addressed by the fund, in
the event it invests in such securities, in order to seek to ensure that it
distributes sufficient income to preserve its status as a regulated investment
company and does not become subject to federal income or excise tax.

If the fund invests in certain pay-in-kind securities, zero coupon securities,
deferred interest securities or, in general, any other securities with original
issue discount (or with market discount if the fund elects to include market
discount in income currently), the fund must accrue income on such investments
for each taxable year, which generally will be prior to the receipt of the
corresponding cash payments. However, the fund must distribute, at least
annually, all or substantially all of its net income, including such accrued
income, to shareholders to qualify as a regulated investment company under the
Code and avoid federal income and excise taxes. Therefore, the fund may have to
dispose of its portfolio securities under disadvantageous circumstances to
generate cash, or may have to leverage itself by borrowing the cash, to satisfy
distribution requirements.

For federal income tax purposes, the fund is permitted to carry forward a net
capital loss for any year to offset its capital gains, if any, during the eight
years following the year of the loss. To the extent subsequent capital gains are
offset by such losses, they would not result in federal income tax liability to
the fund and are not expected to be distributed as such to shareholders. See
Appendix A for the fund's available capital loss carryforwards.

At the time of an investor's purchase of fund shares, a portion of the purchase
price may be attributable to realized or unrealized appreciation in the fund's
portfolio or undistributed taxable income of the fund. Consequently, subsequent
distributions by the fund on these shares from such appreciation or income may
be taxable to such investor even if the net asset value of the investor's shares
is, as a result of the distributions, reduced below the investor's cost for such
shares and the distributions economically represent a return of a portion of the
investment.

Redemptions and exchanges are taxable events for shareholders that are subject
to tax. Shareholders should consult their own tax advisers with reference to
their individual circumstances to determine whether any particular transaction
in fund shares is properly treated as a sale for tax purposes, as the following
discussion assumes, and the tax treatment of any gains or losses recognized in
such transactions. Any loss realized by a shareholder upon the redemption,
exchange or other disposition of shares with a tax holding period of six months
or less will be treated as a long-term capital loss to the extent of any amounts
treated as distributions of long-term capital gain with respect to such shares.

In addition, if Class A shares redeemed or exchanged have been held for less
than 91 days, (1) in the case of a reinvestment in the fund or another mutual
fund at net asset value pursuant to the reinvestment privilege, or (2) in the
case of an exchange, all or a portion of the sales charge paid on such shares is
not included in their tax basis under the Code, to the extent a sales charge
that would otherwise apply to the shares received is reduced pursuant to the
reinvestment or exchange privilege. In either case, the portion of the sales
charge not included in the tax basis of the shares redeemed or surrendered in an
exchange is included in the tax basis of the shares acquired in the reinvestment
or exchange. Losses on redemptions or other dispositions of shares may be
disallowed under "wash sale" rules in the event of other investments in the fund
(including those made pursuant to reinvestment of dividends and/or capital gain
distributions) within a period of 61 days beginning 30 days before and ending 30
days after a redemption or other disposition of shares. In such a case, the
disallowed portion of any loss would be included in the federal tax basis of the
shares acquired in the other investments.

Options written or purchased and futures contracts entered into by the fund on
certain securities, indices and foreign currencies, as well as certain forward
foreign currency contracts, may cause the fund to recognize gains or losses from
marking-to-market even though such options may not have lapsed, been closed out,
or exercised or such futures or forward contracts may not have been performed or
closed out. The tax rules applicable to these contracts may affect the
characterization as long-term or short-term of some capital gains and losses
realized by the fund. Certain options, futures and forward contracts relating to
foreign currency may be subject to Section 988, as described above, and
accordingly produce ordinary income or loss. Additionally, the fund may be
required to recognize gain if an option, futures contract, forward contract,
short sale or other transaction that is not subject to the mark-to-market rules
is treated as a "constructive sale" of an "appreciated financial position" held
by the fund under Section 1259 of the Code. Any net mark-to-market gains and/or
gains from constructive sales may also have to be distributed to satisfy the
distribution requirements referred to above even though no corresponding cash
amounts may concurrently be received, possibly requiring the disposition of
portfolio securities or borrowing to obtain the necessary cash. Losses on
certain options, futures or forward contracts and/or offsetting positions
(portfolio securities or other positions with respect to which the fund's risk
of loss is substantially diminished by one or more options, futures or forward
contracts) may also be deferred under the tax straddle rules of the Code, which
may also affect the characterization of capital gains or losses from straddle
positions and certain successor positions as long-term or short-term. Certain
tax elections may be available that would enable the fund to ameliorate some
adverse effects of the tax rules described in this paragraph. The tax rules
applicable to options, futures, forward contracts and straddles may affect the
amount, timing and character of the fund's income and gains or losses and hence
of its distributions to shareholders.

For purposes of the 70% dividends-received deduction generally available to
corporations under the Code, dividends received by the fund from U.S.
corporations in respect of any share of stock with a tax holding period of at
least 46 days (91 days in the case of certain preferred stock) extending before
and after each dividend held in an unleveraged position and distributed and
designated by the fund may be treated as qualifying dividends. Any corporate
shareholder should consult its tax adviser regarding the possibility that its
tax basis in its shares may be reduced, for federal income tax purposes, by
reason of "extraordinary dividends" received with respect to the shares and, to
the extent such basis would be reduced below zero, current recognition of income
may be required. In order to qualify for the deduction, corporate shareholders
must meet the minimum holding period requirement stated above with respect to
their fund shares, taking into account any holding period reductions from
certain hedging or other transactions or positions that diminish their risk of
loss with respect to their fund shares, and, if they borrow to acquire or
otherwise incur debt attributable to fund shares, they may be denied a portion
of the dividends-received deduction. The entire qualifying dividend, including
the otherwise deductible amount, will be included in determining the excess, if
any, of a corporation's adjusted current earnings over its alternative minimum
taxable income, which may increase a corporation's alternative minimum tax
liability.

The fund may be subject to withholding and other taxes imposed by foreign
countries, including taxes on interest, dividends and capital gains with respect
to its investments in those countries, which would, if imposed, reduce the yield
on or return from those investments. Tax conventions between certain countries
and the U.S. may reduce or eliminate such taxes in some cases. The fund does not
expect to satisfy the requirements for passing through to its shareholders their
pro rata shares of qualified foreign taxes paid by the fund, with the result
that shareholders will not include such taxes in their gross incomes and will
not be entitled to a tax deduction or credit for such taxes on their own tax
returns.

Different tax treatment, including penalties on certain excess contributions and
deferrals, certain pre-retirement and post-retirement distributions and certain
prohibited transactions, is accorded to accounts maintained as qualified
retirement plans. Shareholders should consult their tax advisers for more
information.

Federal law requires that the fund withhold (as "backup withholding") 31% of
reportable payments, including dividends, capital gain distributions and the
proceeds of redemptions (including exchanges) or repurchases of fund shares paid
to shareholders who have not complied with IRS regulations. In order to avoid
this withholding requirement, shareholders must certify on their Account
Applications, or on separate IRS Forms W-9, that the Social Security Number or
other Taxpayer Identification Number they provide is their correct number and
that they are not currently subject to backup withholding, or that they are
exempt from backup withholding. The fund may nevertheless be required to
withhold if it receives notice from the IRS or a broker that the number provided
is incorrect or backup withholding is applicable as a result of previous
underreporting of interest or dividend income.

If, as anticipated, the fund continues to qualify as a regulated investment
company under the Code, it will not be required to pay any Massachusetts income,
corporate excise or franchise taxes or any Delaware corporation income tax.

The description of certain federal tax provisions 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. This description does
not address the special tax rules that may be applicable to particular types of
investors, such as financial institutions, insurance companies, securities
dealers, or tax-exempt or tax-deferred plans, accounts or entities. Investors
other than U.S. persons may be subject to different U.S. tax treatment,
including a possible 30% non-resident alien U.S. withholding tax (or
non-resident alien withholding tax at a lower treaty rate) on amounts treated as
ordinary dividends from the fund and, unless an effective IRS Form W-8, Form
W-8BEN or other authorized withholding certificate is on file, to 31% backup
withholding on certain other payments from the fund. Shareholders should consult
their own tax advisers on these matters and on state, local and other applicable
tax laws.

16.      INVESTMENT RESULTS

QUOTATIONS, COMPARISONS AND GENERAL INFORMATION

From time to time, in advertisements, in sales literature or in reports to
shareholders, the past performance of the fund may be illustrated and/or
compared with that of other mutual funds with similar investment objectives and
to stock or other relevant indices. For example, total return of the fund's
classes may be compared to averages or rankings prepared by Lipper Analytical
Services, Inc., a widely recognized independent service which monitors mutual
fund performance; the S&P 500, an index of unmanaged groups of common stock; the
Dow Jones Industrial Average, a recognized unmanaged index of common stocks of
30 industrial companies listed on the Exchange; or the Russell U.S. Equity
Indexes or the Wilshire Total Market Value Index, which are recognized unmanaged
indexes of broad-based common stocks.

In addition, the performance of the classes of the fund may be compared to
alternative investment or savings vehicles and/or to indexes or indicators of
economic activity, e.g., inflation or interest rates. The fund may also include
securities industry or comparative performance information generally and in
advertising or materials marketing the fund's shares. Performance rankings and
listings reported in newspapers or national business and financial publications,
such as BARRON'S, BUSINESS WEEK, CONSUMERS DIGEST, CONSUMER REPORTS, FINANCIAL
WORLD, FORBES, FORTUNE, INVESTORS BUSINESS DAILY, KIPLINGER'S PERSONAL FINANCE
MAGAZINE, MONEY MAGAZINE, NEW YORK TIMES, SMART MONEY, USA TODAY, U.S. NEWS AND
WORLD REPORT, THE WALL STREET JOURNAL and WORTH, may also be cited (if the fund
is listed in any such publication) or used for comparison, as well as
performance listings and rankings from various other sources including Bloomberg
Financial Markets, CDA/Wiesenberger, Donoghue's Mutual Fund Almanac, Ibbotson
Associates, Investment Company Data, Inc., Johnson's Charts, Kanon Bloch Carre
and Co., Lipper Analytical Services, Inc., Micropal, Inc., Morningstar, Inc.,
Schabacker Investment Management and Towers Data Systems, Inc.

In addition, from time to time quotations from articles from financial
publications such as those listed above may be used in advertisements, in sales
literature or in reports to shareholders of the fund.

The fund may also present, from time to time, historical information depicting
the value of a hypothetical account in one or more classes of the fund since
inception.

In presenting investment results, the fund may also include references to
certain financial planning concepts, including (a) an investor's need to
evaluate his financial assets and obligations to determine how much to invest;
(b) his need to analyze the objectives of various investments to determine where
to invest; and (c) his need to analyze his time frame for future capital needs
to determine how long to invest. The investor controls these three factors, all
of which affect the use of investments in building assets.

One of the primary methods used to measure the performance of a class of the
fund is "total return." Total return will normally represent the percentage
change in value of an account, or of a hypothetical investment in a class of the
fund, over any period up to the lifetime of that class of the fund. Total return
calculations will usually assume the reinvestment of all dividends and capital
gain distributions and will be expressed as a percentage increase or decrease
from an initial value for the entire period or for one or more specified periods
within the entire period. Total return percentages for periods of less than one
year will usually be annualized; total return percentages for periods longer
than one year will usually be accompanied by total return percentages for each
year within the period and/or by the average annual compounded total return for
the period. The income and capital components of a given return may be separated
and portrayed in a variety of ways in order to illustrate their relative
significance. Performance may also be portrayed in terms of cash or investment
values without percentages. Past performance cannot guarantee any particular
future result.

The fund's average annual total return quotations for each of its classes as
that information may appear in the fund's prospectus, this statement of
additional information or in advertising are calculated by standard methods
prescribed by the SEC.

STANDARDIZED AVERAGE ANNUAL TOTAL RETURN QUOTATIONS

Average annual total return quotations for each class of shares are computed by
finding the average annual compounded rates of return that would cause a
hypothetical investment in the class made on the first day of a designated
period (assuming all dividends and distributions are reinvested) to equal the
ending redeemable value of such hypothetical investment on the last day of the
designated period in accordance with the following formula:

                           P(1+T)n[superscript] = ERV

Where:

         P        =        a hypothetical initial payment of $1,000, less the
                           maximum sales load of $57.50 for Class A shares or
                           the deduction of the CDSC for Class B and Class C
                           shares at the end of the period; for Class Y shares,
                           no sales load or CDSC applies

         T        =        average annual total return

         n        =        number of years

         ERV      =        ending redeemable value of the hypothetical $1,000
                           initial payment made at the beginning of the
                           designated period (or fractional portion thereof)

For purposes of the above computation, it is assumed that all dividends and
distributions made by the fund are reinvested at net asset value during the
designated period. The average annual total return quotation is determined to
the nearest 1/100 of 1%.

In determining the average annual total return (calculated as provided above),
recurring fees, if any, that are charged to all shareholder accounts of a
particular class of shares are taken into consideration. For any account fees
that vary with the size of the account, the account fee used for purposes of the
above computation is assumed to be the fee that would be charged to a class's
mean account size.

See Appendix A for the annual total returns for each class of fund shares as of
the most recently completed fiscal year.

19.      APPENDIX B - DESCRIPTION OF SHORT-TERM DEBT, CORPORATE BOND AND
PREFERRED STOCK RATINGS

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") PRIME RATING SYSTEM

Moody's short-term debt ratings are opinions of the ability of issuers to repay
punctually senior debt obligations. These obligations have an original maturity
not exceeding one year, unless explicitly noted.

Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issuers:

Prime-1: Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:

         Leading market positions in well-established industries. High rates of
         return on funds employed.
         Conservative capitalization structure with moderate reliance on debt
         and ample asset protection. Broad margins in earnings coverage of fixed
         financial charges and high internal cash generation. Well-established
         access to a range of financial markets and assured sources of alternate
         liquidity.

Prime-2: Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

Prime-3: Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

Not Prime: Issuers rated Not Prime do not fall within any of the Prime rating
categories.


- --------
1 The ratings indicated herein are believed to be the most recent ratings
available at the date of this statement of additional information for the
securities listed. Ratings are generally given to securities at the time of
issuance. While the rating agencies may from time to time revise such ratings,
they undertake no obligation to do so, and the ratings indicated do not
necessarily represent ratings which will be given to these securities on the
date of the fund's fiscal year-end.

Obligations of a branch of a bank are considered to be domiciled in the country
in which the branch is located. Unless noted as an exception, Moody's rating on
a bank's ability to repay senior obligations extends only to branches located in
countries which carry a Moody's Sovereign Rating for Bank Deposits. Such branch
obligations are rated at the lower of the bank's rating or Moody's Sovereign
Rating for Bank Deposits for the country in which the branch is located.

When the currency in which an obligation is denominated is not the same as the
currency of the country in which the obligation is domiciled, Moody's ratings do
not incorporate an opinion as to whether payment of the obligation will be
affected by actions of the government controlling the currency of denomination.
In addition, risks associated with bilateral conflicts between an investor's
home country and either the issuer's home country or the country where an
issuer's branch is located are not incorporated into Moody's short-term debt
ratings.

If an issuer represents to Moody's that its short-term debt obligations are
supported by the credit of another entity or entities, then the name or names of
such supporting entity or entities are listed within the parenthesis beneath the
name of the issuer, or there is a footnote referring the reader to another page
for the name or names of the supporting entity or entities. In assigning ratings
to such issuers, Moody's evaluates the financial strength of the affiliated
corporations, commercial banks, insurance companies, foreign governments or
other entities, but only as one factor in the total rating assessment.

MOODY'S DEBT RATINGS

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

Aa: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high-grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long-term risk appear somewhat larger than the Aaa securities.

A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper-medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.

Baa: Bonds which are rated Baa are considered as medium-grade obligations (i.e.,
they are neither highly protected nor poorly secured). Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca: Bonds which are rated Ca represent obligations which are speculative in
a high degree. Such issues are often in default or have other marked
shortcomings.

C: Bonds which are rated C are the lowest rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Note: Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa through Caa. The modifier 1 indicated that the obligation
ranks in the higher end of its generic rating category; the modifier 2 indicated
a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

MOODY'S PREFERRED STOCK RATINGS

Because of the fundamental differences between preferred stocks and bonds, a
variation of Moody's familiar bond rating symbols is used in the quality ranking
of preferred stock. The symbols, presented below, are designed to avoid
comparison with bond quality in absolute terms. It should always be borne in
mind that preferred stock occupies a junior position to bonds within a
particular capital structure and that these securities are rated within the
universe of preferred stocks.

aaa: An issue which is rated aaa is considered to be a top-quality preferred
stock. This rating indicates good asset protection and the least risk of
dividend impairment within the universe of preferred stocks.

aa: An issue which is rated aa is considered a high-grade preferred stock. This
rating indicates that there is a reasonable assurance the earnings and asset
protection will remain relatively well maintained in the foreseeable future.

a: An issue which is rated a is considered to be an upper-medium grade preferred
stock. While risks are judged to be somewhat greater then in the aaa and aa
classification, earnings and asset protection are, nevertheless, expected to be
maintained at adequate levels.

baa: An issue which is rated baa is considered to be a medium-grade preferred
stock, neither highly protected nor poorly secured. Earnings and asset
protection appear adequate at present but may be questionable over any great
length of time.

ba: An issue which is rated ba is considered to have speculative elements and
its future cannot be considered well assured. Earnings and asset protection may
be very moderate and not well safeguarded during adverse periods.
Uncertainty of position characterizes preferred stocks in this class.

b: An issue which is rated b generally lacks the characteristics of a desirable
investment. Assurance of dividend payments and maintenance of other terms of the
issue over any long period of time may be small.

caa: An issue which is rated caa is likely to be in arrears on dividend
payments. This rating designation does not purport to indicate the future status
of payments.

ca: An issue which is rated ca is speculative in a high degree and is likely to
be in arrears on dividends with little likelihood of eventual payments.

c: This is the lowest rated class of preferred or preference stock. Issues so
rated can thus be regarded as having extremely poor prospects of ever attaining
any real investment standing.

Note: Moody's applies numerical modifiers 1, 2 and 3 in each rating
classification: the modifier 1 indicates that the security ranks in the higher
end of its generic rating category; the modifier 2 indicates a mid-range ranking
and the modifier 3 indicates that the issue ranks in the lower end of its
generic rating category.

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

A-1: A short-term obligation rated A-1 is rated in the highest category by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

B: A short-term obligation rated B is regarded as having significant speculative
characteristics. The obligor currently has the capacity to meet its financial
commitment on the obligation; however, it faces major ongoing uncertainties
which could lead to the obligor's inadequate capacity to meet its financial
commitment on the obligation.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in payment default. The D rating category
is used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.

STANDARD & POOR'S LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based, in varying degrees, on the following
considerations:

     Likelihood of payment-capacity and willingness of the obligor to meet
     its financial commitment on an obligation in accordance with the terms
     of the obligation;
     Nature of and provisions of the obligation;
     Protection afforded by, and relative position of, the obligation in the
     event of bankruptcy, reorganization, or other arrangement under the
     laws of bankruptcy and other laws affecting creditors' rights.

The issue rating definitions are expressed in terms of default risk. As such,
they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding company obligations.) Accordingly, in the case of
junior debt, the rating may not conform exactly with the category definition.

AAA: An obligation rated AAA has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.

AA: An obligation rated AA differs from the highest-rated obligations only
in small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.

A: An obligation rated A is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than obligations in
higher-rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity of the obligor to meet its financial commitment on the
obligation.

Obligations rated BB, B, CCC, CC, and C are regarded as having significant
speculative characteristics. BB indicates the least degree of speculation and C
the highest. While such obligations will likely have some quality and protective
characteristics, these may be outweighed by large uncertainties or major
exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial or economic conditions which could lead to the
obligor's capacity to meet its financial commitment on the obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated
BB, but the obligor currently has the capacity to meet its financial commitment
on the obligation. Adverse business, financial, or economic conditions will
likely impair the obligor's capacity or willingness to meet its financial
commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial or economic conditions, the obligor is not likely to
have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment.

C: The C rating may be used to cover a situation where a bankruptcy petition has
been filed or similar action has been taken, but payments on this obligation are
being continued.

D: An obligation rated D is in payment default. The D rating category is used
when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments are jeopardized.

Plus (+) or Minus (-): The rating from AA to CCC may be modified by the addition
of a plus or minus sign to show relative standing within the major categories.

r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk, such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

STANDARD & POOR'S PREFERRED STOCK RATINGS

A Standard & Poor's preferred stock rating is an assessment of the capacity and
willingness of an issuer to pay preferred stock dividends and any applicable
sinking fund obligations. A preferred stock rating differs from a bond rating
inasmuch as it is assigned to an equity issue, which is intrinsically different
from, and subordinated to, a debt issue. Therefore, to reflect this difference,
the preferred stock rating symbol will normally not be higher than the debt
rating symbol assigned to, or that would be assigned to, the senior debt of the
same issuer.

Preferred stock ratings are based on the following considerations:

     Likelihood of payment-capacity and willingness of the issuer to meet
     the timely payment of preferred stock dividends and any applicable
     sinking fund requirements in accordance with the terms of the
     obligation;
     Nature of, and provisions of, the issue;
     Relative position of the issue in the event of bankruptcy, reorganization,
     or other arrangement under the laws of bankruptcy and other laws affecting
     creditors' rights.

AAA: This is the highest rating that may be assigned by Standard & Poor's to a
preferred stock issue and indicates an extremely strong capacity to pay the
preferred stock obligations.

AA: A preferred stock issue rated AA also qualifies as a high-quality,
fixed-income security. The capacity to pay preferred stock obligations is very
strong, although not as overwhelming as for issues rated AAA.

A: An issue rated A is backed by a sound capacity to pay the preferred stock
obligations, although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions.

BBB: An issue rated BBB is regarded as backed by an adequate capacity to pay the
preferred stock obligations. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to make payments for a preferred stock in
this category than for issues in the A category.

BB, B, CCC: Preferred stock rated BB, B, and CCC are regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay preferred
stock obligations. BB indicates the lowest degree of speculation and CCC the
highest. While such issues will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.

CC: The rating CC is reserved for a preferred stock issue that is in
arrears on dividends or sinking fund payments, but that is currently paying.

C: A preferred stock rated C is a nonpaying issue.

D: A preferred stock rated D is a nonpaying issue with the issuer in
default on debt instruments.

N.R.: This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular type of obligation as a matter of policy.

Plus (+) or Minus (-): To provide more detailed indications of preferred stock
quality, ratings from AA to CCC may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

COMPARATIVE PERFORMANCE INDEX DESCRIPTIONS

The following securities indices are well known, unmanaged measures of market
performance. Advertisements and sales literature for the fund may refer to these
indices or may present comparisons between the performance of the fund and one
or more of the indices. Other indices may also be used, if appropriate. The
indices are not available for direct investment. The data presented are not
meant to be indicative of the performance of the fund, do not reflect past
performance and do not guarantee future results.

S&P 500. This index is a readily available, carefully constructed, market value
weighted benchmark of common stock performance. Currently, the S&P 500 includes
500 of the largest stocks (in terms of stock market value) in the U.S.

DOW JONES INDUSTRIAL AVERAGE. This is a total return index based on the
performance of stocks of 30 blue chip companies widely held by individuals and
institutional investors. The 30 stocks represent about a fifth of the $8
trillion-plus market value of all U.S. stocks and about a fourth of the value of
stocks listed on the New York Stock Exchange (NYSE).

U.S. SMALL STOCK INDEX. This index is a market value weighted index of the
ninth and tenth deciles of the NYSE, plus stocks listed on the American Stock
Exchange and over the counter with the same or less capitalization as the upper
bound of the NYSE ninth decile.

U.S. INFLATION. The Consumer Price Index for All Urban Consumers (CPI-U), not
seasonally adjusted, is used to measure inflation, which is the rate of change
of consumer goods prices. Unfortunately, the inflation rate as derived by the
CPI is not measured over the same period as the other asset returns. All of the
security returns are measured from one month-end to the next month-end. CPI
commodity prices are collected during the month. Thus, measured inflation rates
lag the other series by about one-half month. Prior to January 1978, the CPI (as
compared with CPI-U) was used. Both inflation measures are constructed by the
U.S. Department of Labor, Bureau of Labor Statistics, Washington, DC.

S&P/BARRA INDEXES. The S&P/BARRA Growth and Value Indexes are constructed by
dividing the stocks in the S&P 500 according to price-to-book ratios. The Growth
Index contains stocks with higher price-to-book ratios, and the Value Index
contains stocks with lower price-to-book ratios. Both indexes are market
capitalization weighted.

MERRILL LYNCH MICRO-CAP INDEX. The Merrill Lynch Micro-Cap Index represents the
performance of 2,036 stocks ranging in market capitalization from $50 million to
$220 million. Index returns are calculated monthly.

LONG-TERM U.S. GOVERNMENT BONDS. The total returns on long-term government bonds
after 1977 are constructed with data from The Wall Street Journal and are
calculated as the change in the flat price or and-interest price. From 1926 to
1976, data are obtained from the government bond file at the Center for Research
in Security Prices (CRSP), Graduate School of Business, University of Chicago.
Each year, a one-bond portfolio with a term of approximately 20 years and a
reasonably current coupon was used and whose returns did not reflect potential
tax benefits, impaired negotiability or special redemption or call privileges.
Where callable bonds had to be used, the term of the bond was assumed to be a
simple average of the maturity and first call dates minus the current date. The
bond was "held" for the calendar year and returns were computed.

INTERMEDIATE-TERM U.S. GOVERNMENT BONDS. Total returns of intermediate-term
government bonds after 1987 are calculated from The Wall Street Journal prices,
using the change in flat price. Returns from 1934 to 1986 are obtained from the
CRSP government bond file.

Each year, one-bond portfolios are formed, the bond chosen is the shortest
noncallable bond with a maturity not less than five years, and this bond is
"held" for the calendar year. Monthly returns are computed. (Bonds with impaired
negotiability or special redemption privileges are omitted, as are partially or
fully tax-exempt bonds starting with 1943.) From 1934 to 1942, almost all bonds
with maturities near five years were partially or fully tax-exempt and were
selected using the rules described above. Personal tax rates were generally low
in that period, so that yields on tax-exempt bonds were similar to yields on
taxable bonds. From 1926 to 1933, there are few bonds suitable for construction
of a series with a five-year maturity. For this period, five-year bond yield
estimates are used.

6-MONTH CDS. Data sources include the Federal Reserve Bulletin and The Wall
Street Journal.

LONG-TERM U.S. CORPORATE BONDS. Since 1969, corporate bond total returns are
represented by the Salomon Brothers Long-Term High-Grade Corporate Bond Index.
As most large corporate bond transactions take place over the counter, a major
dealer is the natural source of these data. The index includes nearly all Aaa-
and Aa-rated bonds with at least 10 years to maturity. If a bond is downgraded
during a particular month, its return for the month is included in the index
before removing the bond from future portfolios.

From 1926 to 1968 the total returns were calculated by summing the capital
appreciation returns and the income returns. For the period 1946 to 1968,
Ibbotson and Sinquefield backdated the Salomon Brothers' index, using Salomon
Brothers' monthly yield data with a methodology similar to that used by Salomon
Brothers for 1969 to 1995. Capital appreciation returns were calculated from
yields assuming (at the beginning of each monthly holding period) a 20-year
maturity, a bond price equal to par, and a coupon equal to the
beginning-of-period yield. For the period 1926 to 1945, Standard & Poor's
monthly high-grade corporate composite yield data were used, assuming a 4%
coupon and a 20-year maturity. The conventional present-value formula for bond
price for the beginning and end-of-month prices was used. (This formula is
presented in Ross, Stephen A., and Westerfield, Randolph W., Corporate Finance,
Times Mirror/Mosby, St. Louis, 1990, p. 97 ["Level-Coupon Bonds"].) The monthly
income return was assumed to be one-twelfth the coupon.

U.S. (30-DAY) TREASURY BILLS. For the U.S. Treasury Bill Index, data from The
Wall Street Journal are used after 1977; the CRSP government bond file is the
source until 1976. Each month a one-bill portfolio containing the shortest-term
bill having not less than one month to maturity is constructed. (The bill's
original term to maturity is not relevant.) To measure holding period returns
for the one-bill portfolio, the bill is priced as of the last trading day of the
previous month-end and as of the last trading day of the current month.

NATIONAL ASSOCIATION OF REAL ESTATE INVESTMENT TRUSTS ("NAREIT") EQUITY REIT
INDEX. All of the data are based upon the last closing price of the month for
all tax-qualified REITs listed on the NYSE, AMEX and NASDAQ. The data are
market-value-weighted. Prior to 1987 REITs were added to the index the January
following their listing. Since 1987 newly formed or listed REITs are added to
the total shares outstanding figure in the month that the shares are issued.
Only common shares issued by the REIT are included in the index. The total
return calculation is based upon the weighting at the beginning of the period.
Only those REITs listed for the entire period are used in the total return
calculation. Dividends are included in the month based upon their payment date.
There is no smoothing of income. Liquidating dividends, whether full or partial,
are treated as income.

RUSSELL U.S. EQUITY INDEXES. The Russell 3000(R) Index (the "Russell 3000") is
comprised of the 3,000 largest U.S. companies as determined by market
capitalization representing approximately 98% of the U.S. equity market. The
average market capitalization is approximately $2.8 billion. The Russell 2500TM
Index measures performance of the 2,500 smallest companies in the Russell 3000.
The average market capitalization is approximately $733.4 million, and the
largest company in the index has an approximate market capitalization of $2.9
billion. The Russell 2000(R) Index measures performance of the 2,000 smallest
stocks in the Russell 3000; the largest company in the index has a market
capitalization of approximately $1.1 billion. The Russell 1000(R) Index (the
"Russell 1000") measures the performance of the 1,000 largest companies in the
Russell 3000. The average market capitalization is approximately $7.6 billion.
The smallest company in the index has an approximate market capitalization of
$1.1 billion. The Russell MidcapTM Index measures performance of the 800
smallest companies in the Russell 1000. The largest company in the index has an
approximate market capitalization of $8.0 billion.

The Russell indexes are reconstituted annually as of July 1, based on May 31
market capitalization rankings.

WILSHIRE REAL ESTATE SECURITIES INDEX. The Wilshire Real Estate Securities Index
is a market capitalization weighted index of 120 publicly traded real estate
securities, such as REITs, real estate operating companies ("REOCs") and
partnerships.

The index contains performance data on five major categories of property:
office, retail, industrial, apartment and miscellaneous. The companies in the
index are 91.66% equity and hybrid REITs and 8.33% REOCs.

STANDARD & POOR'S MIDCAP 400 INDEX. The S&P 400 is a
market-capitalization-weighted index. The performance data for the index were
calculated by taking the stocks presently in the index and tracking them
backwards in time as long as there were prices reported. No attempt was made to
determine what stocks "might have been" in the S&P 400 five or ten years ago had
it existed. Dividends are reinvested on a monthly basis prior to June 30, 1991,
and are reinvested daily thereafter.

LIPPER BALANCED FUNDS INDEX. This index represents equally weighted performance,
adjusted for capital gains distributions and income dividends, of approximately
30 of the largest funds with a primary objective of conserving principal by
maintaining at all times a balanced portfolio of stocks and bonds. Typically,
the stock/bond ratio ranges around 60%/40%.

LEHMAN AGGREGATE BOND INDEX. Composed of the Lehman Government/Corporate Index
and the Mortgage-Backed Securities Index and includes treasury issues, agency
issues, corporate bond issues and mortgage backed securities.

LEHMAN BROTHERS AGGREGATE BOND INDEX. The Lehman Brothers Aggregate Bond Index
is composed of the Lehman Brothers Government/Corporate Index, the Lehman
Brothers Mortgage-Backed Securities Index and the Lehman Brothers Asset-Backed
Securities Index. The index includes fixed rate debt issues rated investment
grade or higher by Moody's Investors Service, Standard & Poor's Corporation or
Fitch Investors Service, in that order. All issues have at least one year to
maturity with intermediate indices including bonds with maturities up to ten
years and long-term indices composed of bonds with maturities longer than ten
years. All returns are market value weighted inclusive of accrued interest.

BANK SAVINGS ACCOUNT. Data sources include the U.S. League of Savings
Institutions Sourcebook; average annual yield on savings deposits in FSLIC
[FDIC] insured savings institutions for the years 1963 to 1987; and The Wall
Street Journal thereafter.

Item 24.  Persons Controlled by or Under Common Control with the Fund

     None.

Item 25.  Indemnification

         Except for the Agreement and Declaration of Trust, dated April 26, 1996
the "Declaration"), establishing the Fund as a business trust under
Delaware law, there is no contract, arrangement or statute under which any
Trustee, officer, underwriter or affiliated person of the Fund is insured or
indemnified. The Declaration provides that no Trustee or officer will be
indemnified against any liability to which the Fund would otherwise be subject
by reason of or for willful misfeasance, bad faith, gross negligence or reckless
disregard of such person's duties.

         Insofar as indemnification for liability arising under the Securities
Act of 1933, as amended (the "1933 Act"), may be available to Trustees, officers
and controlling persons of the Fund pursuant to the foregoing provisions, or
otherwise, the Fund has been advised that in the opinion of the SEC such

                                      C-1
<PAGE>


indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Fund of expenses incurred or
paid by a Trustee, officer or controlling person of the Fund in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, officer
or controlling person in connection with the securities being registered, the
Fund will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

Item 26.  Business and Other Connections of Investment Adviser

     Pioneer Investment Management, Inc. ("Pioneer Investments") is a registered
investment adviser under the Investment Advisers Act of 1940, as amended, and is
a wholly owned subsidiary of The Pioneer Group, Inc. ("Pioneer").  Pioneer
Investments manages investment companies, pension and profit sharing plans,
trusts, estates or charitable organizations and other corporations or
business entities.

     To the knowledge of the Fund, none of Pioneer Investments' directors
or executive officers is or has been during their employment with Pioneer
Investments engaged in any other business, profession, vocation or employment
of a substantial nature for the past two fiscal years, except as noted below.
Certain directors and officers, however, may hold or may have held various

"Management Contracts");

         WHEREAS, the Management Contracts provide that the Manager will bear
all of the Funds' expenses other than those provided in Section 2(c) and 2(d) of
the Management Contracts;

         WHEREAS, Section 2(c)(i) provides that the Funds shall pay charges and
expenses for Fund accounting, pricing and appraisal services and, for those
Funds noted with an asterisk on Exhibit 2 hereto, related overhead, including,
to the extent that such services were performed by personnel of the Manager or
its affiliates, office space and facilities, and personnel compensation,
training and benefits;

         WHEREAS, Section 2(c)(vi) and (vii) provide that the Funds shall pay
(i) fees and expenses involved in registering and maintaining registrations of
the Funds and/or their shares with the Commission, state or blue sky securities
agencies and foreign countries, including the preparation of prospectuses and

expenses of shareholders and Trustees' meetings and of preparing, printing and

         WHEREAS, certain of these activities, as set forth on Exhibit 3 hereto,

administrative staff working at the direction and under the supervision of the
Board of Trustees and Fund counsel.

         NOW THEREFORE, in consideration of the mutual covenants and benefits
set forth herein, the Funds and the Manager do hereby agree as follows:


<PAGE>


         1. The Funds authorize the Manager to perform fund accounting services
on behalf of the Funds, subject to the supervision and direction of the Board of
Trustees. Such services, determined as of the date of this Agreement, are set
forth on Exhibit 2 hereto. These services (the "Bookkeeping Services") may be
revised from time to time on mutual agreement of the parties.

         2. The Funds authorize the Manager to assist with the performance of
the legal services listed on Exhibit 3 hereto (the "Legal Services"). The Legal
Services shall at all times be subject to the supervision and direction of the
Board of Trustees and Fund counsel.

         3. The Trustees recognize that the Bookkeeping Services and the Legal
Services can be performed efficiently by the Manager. The Funds are entering
into this Agreement to achieve the operating and expense benefits of such
efficiency. In authorizing such activities on behalf of the Funds, the Funds
expressly do not delegate to the Manager or its personnel the authority to
render legal advice to, or legal judgments on behalf of, the Funds. Between
meetings of the Trustees, Fund counsel is authorized to determine the services
that may appropriately be provided by the Manager pursuant to this Agreement.

         4. In consideration of its services under this Agreement, the Manager
shall be entitled to be reimbursed for the allocable portion of the direct costs
of the Bookkeeping Services and the Legal Expenses (collectively, the
"Services"). Such allocation shall be based upon the proportion of personnel
time devoted to the Services authorized to be performed on behalf of the Funds
to the total time worked by such personnel, in each case as estimated in good
faith by the Manager and reviewed and approved annually by the Board of
Trustees. Direct costs shall include any out-of-pocket expenses of the Manager
incurred in connection with the Services, the salaries and benefits of personnel
of the Manager who are engaged in the Services pursuant to this Agreement and,
with respect to the Services, a reasonable allocation of overhead (to the extent
permitted under the Management Contracts) associated with the performance of the
Bookkeeping Services. The Manager shall estimate such direct costs and overhead
(as appropriate) in good faith and the Funds shall be entitled to such
supporting information as the Trustees shall reasonably request from time to
time. Allocations of reimbursements paid hereunder among the Funds shall be
subject to annual approval of the Board of Trustees.

         5. The Manager will not be liable for any error of judgment or mistake
of law in the performance of its services under the Agreement, but nothing
contained herein will be construed to protect the Manager against any liability
to the Funds or its shareholders by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties under this Agreement.

         6. Either party hereto may, without penalty, terminate this Agreement
by the giving of 60 days' written notice to the other party.

act solely as investment counsel for such clients and not in any way on behalf
of the Funds or any series thereof.

with respect to the subject matter of this Agreement and its intended to be the
complete and exclusive statement of the terms hereof. It may not be added to or
changed orally, and may not be modified or rescinded except by a writing signed

or unenforceable the remaining terms or provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of
this Agreement in any other jurisdiction.

                                  PIONEER FUND

                   MULTIPLE CLASS PLAN PURSUANT TO RULE 18F-3

        CLASS A SHARES, CLASS B SHARES, CLASS C SHARES AND CLASS Y SHARES

                                  JULY 1, 1997

         Each class of shares of Pioneer Fund (the "Fund") will have the same
relative rights and privileges and be subject to the same sales charges, fees
and expenses, except as set forth below. The Board of Trustees may determine in
the future that other distribution arrangements, allocations of expenses
(whether ordinary or extraordinary) or services to be provided to a class of
shares are appropriate and amend this Plan accordingly without the approval of
shareholders of any class. Except as set forth in the Fund's prospectus, shares
may be exchanged only for shares of the same class of another Pioneer mutual
fund.

         Article I.  Class A Shares

         Class A Shares are sold at net asset value and subject to the initial
sales charge schedule or contingent deferred sales charge ("CDSC") and minimum
purchase requirements as set forth in the Fund's prospectus. Class A Shares
shall be entitled to the shareholder services set forth from time to time in the
Fund's prospectus with respect to Class A Shares. Class A Shares are subject to
fees calculated as a stated percentage of the net assets attributable to Class A
Shares under the Fund's Class A Rule 12b-1 Distribution Plan as set forth in
such Distribution Plan. The Class A Shareholders have exclusive voting rights,
if any, with respect to the Class A Rule 12b-1 Distribution Plan. Transfer
agency fees are allocated to Class A Shares on a per account basis except to the
extent, if any, such an allocation would cause the Fund to fail to satisfy any
requirement necessary to obtain or rely on a private letter ruling from the
Internal Revenue Service ("IRS") relating to the issuance of multiple classes of
shares. Class A Shares shall bear the costs and expenses associated with
conducting a shareholder meeting for matters relating to Class A Shares.

         The initial purchase date for Class A Shares acquired through (i)
reinvestment of dividends on Class A Shares or (ii) exchange from another
Pioneer mutual fund will be deemed to be the date on which the original Class A
shares were purchased.

         Article II.  Class B Shares

         Class B Shares are sold at net asset value per share without the
imposition of an initial sales charge. However, Class B Shares redeemed within a
specified number of years of purchase will be subject to a CDSC as set forth in
the Fund's prospectus. Class B Shares are sold subject to the minimum purchase
requirements set forth in the Fund's prospectus. Class B Shares shall be
entitled to the shareholder services set forth from time to time in the Fund's
prospectus with respect to Class B Shares.


<PAGE>


Class B Shares are subject to fees calculated as a stated percentage of the
net assets attributable to Class B Shares under the Class B Rule 12b-1
Distribution Plan as set forth in such Distribution Plan. The Class B
Shareholders of the Fund have exclusive voting rights, if any, with respect to
the Fund's Class B Rule 12b-1 Distribution Plan. Transfer agency fees are
allocated to Class B Shares on a per account basis except to the extent, if any,
such an allocation would cause the Fund to fail to satisfy any requirement
necessary to obtain or rely on a private letter ruling from the IRS relating to
the issuance of multiple classes of shares. Class B Shares shall bear the costs
and expenses associated with conducting a shareholder meeting for matters
relating to Class B Shares.

         Class B Shares will automatically convert to Class A Shares of the Fund
at the end of a specified number of years after the initial purchase date of
Class B Shares, except as provided in the Fund's prospectus. Such conversion
will occur at the relative net asset value per share of each class without the
imposition of any sales charge, fee or other charge. The conversion of Class B
Shares to Class A Shares may be suspended if it is determined that the
conversion constitutes or is likely to constitute a taxable event under federal
income tax law.

         The initial purchase date for Class B Shares acquired through (i)
reinvestment of dividends on Class B Shares or (ii) exchange from another
Pioneer mutual fund will be deemed to be the date on which the original Class B
Shares were purchased.

         Article III.  Class C Shares

         Class C Shares are sold at net asset value per share without the
imposition of an initial sales charge. However, Class C Shares redeemed within
one year of purchase will be subject to a CDSC as set forth in the Fund's
prospectus. Class C Shares are sold subject to the minimum purchase requirements
set forth in the Fund's prospectus. Class C Shares shall be entitled to the
shareholder services set forth from time to time in the Fund's prospectus with
respect to Class C Shares. Class C Shares are subject to fees calculated as a
stated percentage of the net assets attributable to Class C Shares under the
Class C Rule 12b-1 Distribution Plan as set forth in such Distribution Plan. The
Class C Shareholders of the Fund have exclusive voting rights, if any, with
respect to the Fund's Class C Rule 12b-1 Distribution Plan. Transfer agency fees
are allocated to Class C Shares on a per account basis except to the extent, if
any, such an allocation would cause the Fund to fail to satisfy any requirement
necessary to obtain or rely on a private letter ruling from the IRS relating to
the issuance of multiple classes of shares. Class C Shares shall bear the costs
and expenses associated with conducting a shareholder meeting for matters
relating to Class C Shares.

         The initial purchase date for Class C Shares acquired through (i)
reinvestment of dividends on Class C Shares or (ii) exchange from another
Pioneer mutual fund will be deemed to be the date on which the original Class C
shares were purchased.

         Article IV.  Class Y Shares

         Class Y Shares are sold at net asset value per share without the
imposition of an initial sales charge. Class Y Shares are not subject to a CDSC
upon redemption regardless of the length of the period of time such shares are
held. Class Y Shares are sold subject to the minimum purchase requirements set
forth in the Fund's prospectus. Class Y Shares shall be entitled to the
shareholder services set forth from time to time in the Fund's prospectus with
respect to Class Y Shares. Class Y Shares are not subject to fees payable under
a distribution or other plan adopted pursuant to Rule 12b-1 under the Investment
Company Act of 1940, as amended (the "Act"). The Class Y Shareholders of the
Fund have exclusive voting rights, if any, with respect to the Fund's possible
future adoption of a Class Y Rule 12b-1 Distribution Plan. Transfer agency fees
are allocated to Class Y Shares on a per account basis except to the extent, if
any, such an allocation would cause the Fund to fail to satisfy any requirement
necessary to obtain or rely on a private letter ruling from the IRS relating to
the issuance of multiple classes of shares. Class Y Shares shall bear the costs
and expenses associated with conducting a shareholder meeting for matters
relating to Class Y Shares.

         The initial purchase date for Class Y Shares acquired through (i)
reinvestment of dividends on Class Y Shares or (ii) exchange from another
Pioneer mutual fund will be deemed to be the date on which the original Class Y
Shares were purchased.

         Article V.  Approval by Board of Trustees

         This Plan shall not take effect until it has been approved by the vote
of a majority (or whatever greater percentage may, from time to time, be
required under Rule 18f-3 under the Act) of (a) all of the Trustees of the Fund
and (b) those of the Trustees who are not "interested persons" (as such term may
be from time to time defined under the Act) of the Fund.

         Article VI.  Amendments

         No material amendment to the Plan shall be effective unless it is
approved by the Board of Trustees in the same manner as is provided for approval
of this Plan in Article V.
