Basic information about the fund


Investment objective
As high a level of current income exempt from federal income taxes as possible
consistent with the preservation of capital.



Principal investment strategies
The fund invests primarily in high quality securities that provide income that
is exempt from federal tax and not subject to alternative minimum tax (AMT).
These investments include bonds, notes and other debt instruments issued by or
on behalf of states, territories and possessions of the United States and the
District of Columbia and their political subdivisions, agencies or
instrumentalities. Normally, the fund invests at least 80% of its net assets in
these securities.

The fund may invest in securities of any maturity. The fund invests in
securities rated in the three highest rating categories by Standard & Poor's
Ratings Group or Moody's Investors Service or determined by Pioneer Investment
Management, Inc., the fund's investment adviser, to be of comparable credit
quality.

The fund may invest 25% or more of its assets in issuers in any one or more
states or securities the payments on which are derived from gas, electric,
telephone, sewer and water segments of the municipal bond market. The fund may
also invest 25% or more of its assets in industrial development bonds.


Pioneer considers both broad economic factors and issuer specific factors in
selecting a portfolio designed to achieve the fund's investment objective. In
assessing the appropriate maturity and rating weighting of the fund's portfolio,
Pioneer considers a variety of factors that are expected to influence economic
activity and interest rates. These factors include fundamental economic
indicators, such as the rates of economic growth and inflation, Federal Reserve
monetary policy and the relative value of the U.S. dollar compared to other
currencies. Once Pioneer determines the preferable portfolio characteristics,
Pioneer selects individual securities based upon the terms of the securities
(such as yields compared to U.S. Treasuries or comparable issues), liquidity and
rating and issuer diversification. Pioneer also employs due diligence and
fundamental research, an evaluation of the issuer based on its financial
statements and operations, to assess an issuer's credit quality, taking into
account financial condition, future capital needs and potential for change in
rating. In making these portfolio decisions, Pioneer relies on the knowledge,
experience and judgment of its staff who have access to a wide variety of
research.

--------------------------------------------------------------------------------
     An investment in the fund is not a bank deposit and is not insured or
     guaranteed by the Federal Deposit Insurance Corporation or any other
     government agency.

Principal risks of investing in the fund
Even though the fund seeks current income exempt from federal income tax, you
could lose money on your investment or not make as much as if you invested
elsewhere if:

[]   Interest rates go up, causing the value of the fund's investments to
     decline

[]   The issuer of a security owned by the fund defaults on its obligation to
     pay principal and/or interest or has its credit rating downgraded
[]   New federal or state legislation adversely affects the tax-exempt status of
     securities held by the fund or the financial ability of municipalities to
     repay these obligations
[]   The issuer of a security owned by the fund may not be able to make timely
     payments because of a general economic downturn or increased governmental
     costs
[]   To the extent the fund concentrates its investments in a single state or
     securities the payments on which are dependent upon a single industry, the
     fund will be more susceptible to risks associated with that state or
     industry
[]   Pioneer is incorrect in its expectation of changes in interest rates or the
     credit quality of an issuer


Although distributions of interest income from the fund's tax-exempt securities
are generally exempt from federal income tax, distributions from other sources,
including capital gain distributions and any gains on the sale of your shares,
are not. You should consult a tax advisor about whether an alternative minimum
tax applies to you and about state and local taxes on your fund distributions.



                                                                               2

Example

This example helps you compare the cost 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 high quality securities that provide
income that is exempt from federal tax.

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).

More on rating criteria
If a rating organization downgrades the quality rating assigned to one or more
of the fund's portfolio securities, Pioneer will consider what actions, if any,
are appropriate including selling the downgraded security or purchasing
additional high quality securities as soon as it is prudent to do so.

Taxable investments
The fund may invest up to 20% of its net assets in securities of other
investment companies, high quality commercial paper, U.S. government
securities, U.S. or foreign bank instruments and repurchase agreements.

Temporary investments

Normally, the fund invests substantially all of its assets to meet its
investment objective. For temporary defensive purposes, the fund may depart from
its principal investment strategies and invest part or all of its assets in
securities with remaining maturities of less than one year or may hold cash or
cash equivalents. 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 debt securities the fund normally invests in 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 receive larger distributions 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 non-principal purposes, including:
[]   As a hedge against adverse changes in interest rates
[]   As a substitute for purchasing or selling securities
[]   To increase the fund's return as a non-hedging strategy that may be
     considered speculative

Even a small investment in derivatives can have a significant impact on the
fund's exposure to interest 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,
1999, the firm had more than $24 billion in assets under management worldwide
including more than $23 billion in U.S. mutual funds. The firm's U.S. mutual
fund investment history includes creating 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 a team
of fixed income portfolio managers and analysts supervised by Sherman B. Russ
and Kenneth J. Taubes.

Mr. Russ and Mr. Taubes are jointly responsible for overseeing Pioneer's U.S.
and global fixed income team. Mr. Russ is a senior vice president of Pioneer.
He joined Pioneer in 1983 as an assistant portfolio manager and has been an
investment professional since 1962. Mr. Taubes joined Pioneer as a senior vice
president in September 1998 and has been an investment professional since 1986.
Prior to joining Pioneer, Mr. Taubes had served since 1991 as a senior vice
president and senior portfolio manager for several Putnam Investments
institutional accounts and mutual funds.

Mr. Russ, Mr. Taubes and their 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, most
recently as chief investment officer at another investment adviser.

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 annual fee is equal to 0.50%
of the fund's average daily net assets up to $250 million, 0.48% of the next $50
million and 0.45% on assets over $300 million. The fee is normally computed
daily and paid monthly.

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.




                                                                               6

Buying, exchanging and selling shares


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.


You buy or sell shares at the share price. 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:
[]   How long you expect to own the shares
[]   The expenses paid by each class
[]   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 subject to other types of sales charges.

-------------------------[Magnifying Glass graphic]-----------------------------
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.

Buying, exchanging and selling shares


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
sale 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.

See "Qualifying for a reduced sales charge" for more information.

Sales charges: Class B shares
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:

[]   Shares purchased by reinvesting dividends and capital gain distributions
     will convert to Class A shares at the same time as shares on which the
     dividend or distribution was paid
[]   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 income tax. Conversion may not occur if the
Internal Revenue Service deems it a taxable event for federal tax purposes.

[]   You do not pay a CDSC on reinvested dividends or distributions
[]   In determining the number of years since your purchase, all purchases are
     considered to have been made on the first day of that month (quarter for
     shares purchased before October 1, 1998)
[]   If you sell only some of your shares, the transfer agent will first sell
     your shares that are not subject to any CDSC and then the shares that you
     have owned the longest

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
[]   recommends purchases of Pioneer mutual funds to,
[]   permits solicitation of, or
[]   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:

[]   If you plan to invest at least $100,000 (excluding any reinvestment of
     dividends and capital gain distributions) in the fund's Class A shares
     during the next 13 months
[]   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:

[]   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;
[]   You paid a sales charge on the original purchase of the shares sold; and

[]   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 described under Section 401(a), 403(b) or 457
of the Internal Revenue Code that has 1,000 or more eligible employees or at
least $10 million in total 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:

     a participant in an employer-sponsored plan. For UGMAs, UTMAs and trust
     accounts, the waiver applies only upon the death of all beneficial owners;

[]   You become disabled (within the meaning of Section 72 of the Internal
     Revenue Code) 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;
[]   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);

[]   The distribution is from any type of IRA, 403(b) or employer-sponsored plan
     described under Section 401(a) or 457 of the Internal Revenue Code 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, in which case the distribution amount may exceed 10% (based
        solely on plan assets held in Pioneer mutual funds);


                                                                              14

     plan described under Section 401(a) of the Internal Revenue Code or to a
     participant in an employer-sponsored 403(b) plan or employer-sponsored 457

Buying, exchanging and selling shares


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 share price 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

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 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.
---------------------------------Column graphic---------------------------------

You may have to pay income taxes on a sale or an exchange.
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Good order means that:
[]   You have provided adequate instructions
[]   There are no outstanding claims against your account

[]   There are no transaction limitations on your account
[]   If you have any fund share certificates, you submit them and they are
     signed by each record owner exactly as the shares are registered
[]   Your request includes a signature guarantee if you:
     -  Are selling over $100,000 or exchanging over $500,000 worth of shares
     -  Changed your account registration or address within the last 30 days
     -  Instruct the transfer agent to mail the check to an address different
        from the one on your account
     -  Want the check paid to someone other than the account owner(s)
     -  Are transferring the sale proceeds to a Pioneer mutual fund account with

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 deductions, 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 establish automatic exchange:
[]   You must select exchanges on a monthly or quarterly basis
[]   Both the originating and receiving accounts must have identical
     registrations

[]   The originating account must have 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.

<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:
[]   Your account must have a total value of at least $10,000 when you establish
     your plan
[]   You must request a periodic withdrawal of at least $50
[]   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.

[]   Redeeming shares for which you hold a share certificate
[]   Requesting certain types of changes for your existing account

You can obtain a signature guarantee from most broker-dealers, banks, credit
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.

Exchange limitation

The fund's exchange limitation is intended to discourage short-term trading in
fund shares. Short-term trading can increase the expenses incurred by the fund
and make portfolio management less efficient. In determining whether the
exchange redemption limit has been reached, Pioneer may aggregate a series of
exchanges (each valued at less than $25,000) and/or fund accounts that appear to
be under common ownership or control. Pioneer may view accounts for which one
person gives instructions or accounts that act on advice provided by a single
source to be under common control.

The exchange limitation does not apply to automatic exchange transactions or to
exchanges made by participants in employer-sponsored retirement plans qualified
under Section 401(a) of the Internal Revenue Code. The exchange limitation does
not apply to accounts that have a written exchange agreement with the
distributor. The exchange limitation may not apply to transactions made through
an omnibus account for 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. On New York Stock Exchange
holidays or on days when the exchange closes early, the telephone center will
adjust its hours accordingly. 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. If you are legally required to obtain a
certificate, you may request one for your Class A shares only. A fee may be
charged for this service.

Other policies
The fund may suspend transactions in shares 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 redeem in kind by delivering portfolio securities
to a redeeming shareowner, provided that the fund must pay redemptions in cash
if a shareowner's aggregate redemptions in a 90-day period are less than
$250,000 or 1% of the fund's net assets.


-------------------------[Magnifying Glass graphic]-----------------------------
You may make up to four exchange redemptions of $25,000 or more per account per
calendar year out of the fund. Except as noted, you may make any number of
exchanges of less than $25,000.

Dividends, capital gains and taxes


Dividends and capital gains

The fund declares a dividend daily. The dividend consists of substantially all
of the fund's net income. You begin to earn dividends on the first business day
following receipt of payment for shares. You continue to earn dividends up to
and including the date of sale. Dividends are normally paid on the last business
day of the month. The fund generally pays any distributions of net short- and
long-term capital gains in November. The fund may also pay dividends and capital
gain 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 distribution, generally you will pay a higher price per share and you
will pay taxes on the amount of the distribution whether you reinvest the
distribution or receive it as cash.

Taxes

For federal income tax purposes, your distributions from the fund's tax-exempt
interest, called "exempt-interest dividends," are exempt from regular federal
income tax. Your distributions from the fund's net long-term capital gains are
considered long-term capital gains. Dividends that are not exempt-interest
dividends and short-term capital gain distributions are taxable as ordinary
income. Any taxable dividends and distributions are taxable, whether you take
payment in cash or reinvest them to buy additional fund shares. When you sell or
exchange fund shares you will generally recognize a capital gain or capital loss
in an amount equal to the difference between the net amount of sale proceeds
(or, in the case of an exchange, the fair market value of the shares) that you
receive and your tax basis for the shares that you sell or exchange. In January
of each year the fund will mail to you information about your dividends,
distributions and any 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 (other than exempt-interest dividends) and distributions,
sale proceeds and any other payments to you.

You should ask your own tax adviser about any federal and state tax
considerations, including possible state and local income taxation of the fund's
exempt-interest dividends and other distributions. 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
organized as a Nebraska corporation in 1968 and reorganized as a Delaware
business trust in June 1994. Prior to December 1, 1993, the fund was called
Mutual of Omaha Tax-Free Income Fund, Inc. and prior to June 30, 1994 was called
Pioneer Tax-Free Income Fund, Inc.

2.    INVESTMENT POLICIES, RISKS AND RESTRICTIONS


The prospectus presents the investment objective and the principal investment
strategies and risks of the fund. This section supplements the disclosure in the
fund's prospectus 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 (other than the
limitations on borrowing and illiquid securities). 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

The investment objective of the fund is to seek as high a level of income exempt
from federal income tax as possible, consistent with preservation of capital. To
achieve this objective, the fund intends to invest in a diversified portfolio of
obligations issued by or on behalf of states, counties and municipalities of the
U.S. and their authorities and political subdivisions ("Tax-Exempt Bonds"), the
interest on which is excluded from gross income for federal income tax purposes.
All of the fund's assets will consist of: (1) Tax-Exempt Bonds which are rated
at the time of purchase within the three highest grades assigned by Moody's
Investors Service, Inc. ("Moody's") (Aaa, Aa or A) or Standard & Poor's Ratings
Group ("S&P") (AAA, AA, A); (2) temporary and/or taxable investments as
described in the prospectus; and (3) cash or cash equivalents. While ratings at
the time of purchase will determine which securities may be acquired, a
subsequent reduction in rating will not require the fund to dispose of the
securities. Investment in lower-quality securities may provide higher yields
than higher-rated securities; however, the added risk of investing in lower
quality securities might not be consistent with preservation of capital. The
ratings of Moody's and S&P represent their opinions as to the quality of the
Tax-Exempt Bonds which they undertake to rate. It should be emphasized, however,
that ratings are general and are not absolute standards of quality.
Consequently, Tax-Exempt Bonds with the same maturity, coupon and rating may
have different yields while bonds of the same maturity and coupon with different
ratings may have the same yield. There is no assurance the fund will attain its
investment objective. See Appendix B for a description of rating categories.

Municipal Obligations

The term "municipal obligations" generally is understood to include debt
obligations issued by municipalities to obtain funds for various public
purposes, the interest on which is, in the opinion of bond counsel to the
issuer, excluded from gross income for federal income tax purposes. In addition,
if the proceeds from private activity bonds are used for the construction,
repair or improvement of privately operated industrial or commercial facilities,
the interest paid on such bonds may be excluded from gross income for federal
income tax purposes, although current federal tax laws place substantial
limitations on


                                       2
<PAGE>

the size of these issues. The fund's distributions of any interest it earns on
municipal obligations will be taxable to shareholders as ordinary income.

The two principal classifications of municipal obligations are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its faith, credit, and taxing power for the payment of
principal and interest. Revenue bonds are payable from the revenues derived from
a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source, but not from the
general taxing power. Sizable investments in these obligations could involve an
increased risk to the fund should any of the related facilities experience
financial difficulties. Private activity bonds are in most cases revenue bonds
and do not generally carry the pledge of the credit of the issuing municipality.
There are, of course, variations in the security of municipal obligations, both
within a particular classification and between classifications.


The fund may invest more than 25% of its total assets in securities the
payments on which are derived from gas, electric, telephone, sewer and water
segments of the municipal bond market. In view of this, an investment in the
fund should be made with an understanding of the characteristics of these
economic sectors and the potential risks of such an investment. Sector-wide
problems include the effects of fluctuating economic conditions, energy
conservation practices on levels of usage, difficulties in obtaining timely and
adequate rate relief, compliance with environmental regulations, increasing
capital expenditures and uncertainties with respect to fuel availability at
reasonable prices. The fund does not consider broader economic sectors of the
municipal bond market such as the utilities sector to be a single industry and
will not purchase securities if more than 25% of its total assets would be
invested in any one industry. For purposes of this limitation, Tax-Exempt Bonds,
except those issued for the benefit of non-governmental users, are not
considered to be part of an industry. The fund may invest 25% or more of its
total assets in Tax-Exempt Bonds of issuers in any one state or it may invest
25% or more of its total assets in industrial development bonds.

The yields on Tax-Exempt Bonds are dependent on a variety of factors, including
general money market conditions, general conditions of the Tax-Exempt Bond
market, the size of a particular offering, the maturity of the obligation, and
the rating of the issue. The value of outstanding Tax-Exempt Bonds will vary as
a result of changing evaluations of the ability of their issuers to meet the
interest and principal payments. Such values will also change in response to
changes in the interest rates payable on new issues of Tax-Exempt Bonds. Should
such interest rates rise, the values of outstanding bonds, including those held
in the fund's portfolio, will decline and (if purchased at principal amount)
would sell at a discount, and, if such interest rates fall, the values of
outstanding bonds will increase and (if purchased at principal amount) would
sell at a premium. Changes in the value of the Tax-Exempt Bonds held in the
fund's portfolio arising from these or other factors will cause changes in the
net asset value per share of the fund.

From time to time, proposals have been introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on Tax-Exempt Bonds. It can be expected that similar proposals may be
introduced in the future. If such a proposal were enacted, the availability of
Tax-Exempt Bonds for investment by the fund and the value of the fund's
portfolio would be affected. Additionally, the fund would reevaluate its
investment objective and policies and consider changes in the structure of the
fund.

Municipal Lease Obligations

Municipal lease obligations or installment purchase contract obligations
(collectively, "lease obligations") have special risks not ordinarily associated
with other Tax-Exempt Bonds (as set forth in the prospectus). Although lease
obligations do not constitute general obligations of the municipality for which
the municipality's taxing power is pledged, a lease obligation ordinarily is
backed by the municipality's covenant to budget for, appropriate and make the
payments due under the lease obligations. However, certain lease obligations
contain "non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for such purpose on a yearly basis. In addition to the
non-appropriation risk, these securities represent a relatively new type of
financing that has not yet developed the depth of marketability associated with
more conventional bonds. Although non-appropriation lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. The fund will seek to minimize these risks.

In determining the liquidity of municipal lease obligations, Pioneer Investment
Management, Inc. ("Pioneer"), the fund's investment adviser, under guidelines
established by the fund's Board of Trustees, will consider: (1) the essential
nature of the leased property; and (2) the likelihood that the municipality will
discontinue appropriating funding for the leased property because the property
is no longer deemed essential to the operation of the municipality.

If leased property is determined not to be essential in nature or if there is a
likelihood that the municipality will discontinue appropriating funding, then
the following factors will also be considered in determining liquidity:

(1) any relevant factors related to the general credit quality of the
municipality, which may include: (a) whether the lease can be canceled; (b) what
assurance there is that the assets represented by the lease can be sold; (c) the
strength of the lessee's general credit (e.g., its debt, administrative,
economic and financial characteristics); and (d) the legal recourse in the event
of failure to appropriate.

(2) any relevant factors related to the marketability of the municipal lease
obligation which may include: (a) the frequency of trades and quotes for the
obligation; (b) the number of dealers willing to purchase or sell the obligation
and the number of other potential purchasers; (c) the willingness of dealers to
undertake to make a market in the obligation; and (d) the nature of the
marketplace trades, including the time needed to dispose of the obligation, the
method of soliciting offers, and the mechanics of transfer.

Zero Coupon and Deferred Interest Bonds

Tax-Exempt Bonds in which the fund may invest also include zero coupon bonds and
deferred interest bonds. Zero coupon bonds and deferred interest bonds are debt
obligations which are issued at a significant discount from face value. While
zero coupon bonds do not require the periodic payment of interest, deferred
interest bonds provide for a period of delay before the regular payment of
interest begins. The discount approximates the total amount of interest the
bonds will accrue and compound over the period until maturity or the first
interest payment date at a rate of interest reflecting the market rate of the
security at the time of issuance. Zero coupon bonds and deferred interest bonds
benefit the issuer by mitigating its need for cash to meet debt service but also
require a higher rate of return to attract investors who are willing to defer
receipt of such cash. Such investments may experience greater volatility in
value


                                       4
<PAGE>

than debt obligations which make regular payments of interest. The fund will
accrue income on such investments for tax and accounting purposes, which is
distributable to shareholders. Since no cash is received at the time of accrual,
the fund may be required to liquidate other portfolio securities to satisfy its
distribution obligations.

Residual Interests in Municipal Securities

Certain municipal securities are divided into short-term and long-term
components. The short-term component has a long-term maturity, but pays interest
at a short-term rate that is reset by means of a "dutch auction" or similar
method at specified intervals (typically 35 days). The long-term component or
"residual interest" pays interest at a rate that is determined by subtracting
the interest paid on the short-term component from the coupon rate on the
municipal securities themselves. Consequently, the interest rate paid on
residual interests will increase when short-term interest rates are declining
and will decrease when short-term interest rates are increasing. This interest
rate adjustment formula results in the market value of residual interests being
significantly more volatile than that of ordinary municipal securities. In a
declining interest rate environment, residual interests can provide the fund
with a means of increasing or maintaining the level of tax-exempt interest paid
to shareholders. However, because of the market volatility associated with
residual interests, the fund will not invest more than 10% of its total assets
in residual interests in municipal securities.

U.S. Government Securities

U.S. government securities in which the fund may invest include debt obligations
of varying maturities issued by the U.S. Treasury or issued or guaranteed by an
agency or instrumentality of the U.S. government, including the Federal Housing
Administration, Federal Financing Bank, Farmers Home Administration,
Export-Import Bank of the U.S., Small Business Administration, Government
National Mortgage Association ("GNMA"), General Services Administration, Central
Bank for Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks,
Federal Home Loan Mortgage Corporation ("FHLMC"), Federal National Mortgage
Association ("FNMA"), Maritime Administration, Tennessee Valley Authority,
District of Columbia Armory Board, Student Loan Marketing Association,
Resolution Trust Corporation and various institutions that previously were or
currently are part of the Farm Credit System (which has been undergoing
reorganization since 1987). Some U.S. government securities, such as U.S.
Treasury bills, Treasury notes and Treasury bonds, which differ only in their
interest rates, maturities and times of issuance, are supported by the full
faith and credit of the United States. Others are supported by: (i) the right of
the issuer to borrow from the U.S. Treasury, such as securities of the Federal
Home Loan Banks; (ii) the discretionary authority of the U.S. government to
purchase the agency's obligations, such as securities of the FNMA; or (iii) only
the credit of the issuer, such as securities of the Student Loan Marketing
Association. No assurance can be given that the U.S. government will provide
financial support in the future to U.S. government agencies, authorities or
instrumentalities that are not supported by the full faith and credit of the
United States. Securities guaranteed as to principal and interest by the U.S.
government, its agencies, authorities or instrumentalities include: (i)
securities for which the payment of principal and interest is backed by an
irrevocable letter of credit issued by the U.S. government or any of its
agencies, authorities or instrumentalities; and (ii) participations in loans
made to foreign governments or other entities that are so guaranteed. The
secondary market for certain of these participations is limited and, therefore,
may be regarded as illiquid.


                                       5
<PAGE>

U.S. government securities may include zero coupon securities that may be
purchased when yields are attractive and/or to enhance portfolio liquidity. Zero
coupon U.S. government securities are debt obligations that are issued or
purchased at a significant discount from face value. The discount approximates
the total amount of interest the security will accrue and compound over the
period until maturity or the particular interest payment date at a rate of
interest reflecting the market rate of the security at the time of issuance.
Zero coupon U.S. government securities do not require the periodic payment of
interest. These investments benefit the issuer by mitigating its need for cash
to meet debt service, but also require a higher rate of return to attract
investors who are willing to defer receipt of cash. These investments may
experience greater volatility in market value than U.S. government securities
that make regular payments of interest. The fund accrues income on these
investments for tax and accounting purposes, which is distributable to
shareholders and which, because no cash is received at the time of accrual, may
require the liquidation of other portfolio securities to satisfy the fund's
distribution obligations, in which case the fund will forego the purchase of
additional income producing assets with these funds. Zero coupon U.S. government
securities include STRIPS and CUBES, which are issued by the U.S. Treasury as
component parts of U.S. Treasury bonds and represent scheduled interest and
principal payments on the bonds.

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 fund will
not earn income on these securities until delivered. 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."

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 non-U.S. 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.


                                       6
<PAGE>

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.



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.


                                       7
<PAGE>

Portfolio Turnover

The fund will limit portfolio turnover to the extent practicable and consistent
with its investment objective and policies. While it does not intend to engage
in short-term trading, the fund will not preclude itself from taking advantage
of short-term trends and yield disparities that might occur from time to time. A
higher portfolio turnover rate will result in correspondingly higher transaction
costs. See Appendix A for the fund's annual portfolio turnover rate.

Futures Contracts


To hedge against changes in securities prices or interest rates or to seek to
increase total return, the fund may purchase and sell various kinds of futures
contracts. The fund may also enter into closing purchase and sale transactions
with respect to any of such contracts. The futures contracts may be based on
various securities (such as U.S. government securities), securities indices and
other financial instruments and indices. The fund will engage in futures
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").

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.

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 will usually be liquidated in
this manner, the fund may instead make, or take, delivery of the underlying
securities whenever it appears economically advantageous to do so. A clearing
corporation associated with the exchange on which futures on securities 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 and rate of return 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 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. 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


                                       8
<PAGE>

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 then available in the applicable market to be less favorable
than prices or rates that are currently available.

Other Considerations. The fund will engage in futures 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 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 that the fund owns, or futures
contracts will be purchased to protect the fund against an increase in the price
of securities 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 position, the fund will have purchased, or will be in the process of
purchasing, equivalent amounts of related securities in the cash market at the
time when the futures 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 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 the amounts of initial margin deposits on the
fund's existing non-hedging futures contracts would not exceed 5% of the market
value of the fund's total assets. The fund will engage in transactions in
futures contracts 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 involve brokerage costs, require margin deposits and, in the
case of contracts obligating the fund to purchase securities, require the fund
to segregate assets to cover such contracts.

While transactions in futures contracts may reduce certain risks, such
transactions themselves entail certain other risks. Thus, while the fund may
benefit from the use of futures, unanticipated changes in interest rates or
securities prices may result in a poorer overall performance for the fund than
if it had not entered into any futures contracts. 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.

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.

Money Market Instruments. The fund may invest in short term money market
instruments including commercial bank obligations and commercial paper. These
instruments may be denominated in both U.S. and non-U.S. currency. The fund's
investment in commercial bank obligations includes certificates of deposit
("CDs"), time deposits ("TDs") and bankers' acceptances. Obligations of foreign
branches of U.S. banks and of foreign banks may be general obligations of the
parent bank in addition to the issuing bank, or may be limited by the terms of a
specific obligation and by government regulation. As with investment in non-U.S.
securities in general, investments in the obligations of foreign branches of
U.S. banks and of foreign banks may subject the fund to investment risks that
are different in some respects from those of investments in obligations of
domestic issuers.


The fund's investments in commercial paper consist of short-term (usually from 1
to 270 days) unsecured promissory notes issued by corporations in order to
finance their current operations.

Investment Restrictions


In compliance with an informal position taken by the staff of the SEC regarding
leverage, the fund will not purchase securities during the current fiscal 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


                                       10
<PAGE>

holders of a "majority of the outstanding voting securities" (as defined in the
1940 Act) of the fund. For this purpose, a majority of the outstanding shares of
the fund means the vote of the lesser of:

1.    67% or more of the shares represented at a meeting, if the holders of more
      than 50% of the outstanding shares are present in person or by proxy, or

2.    more than 50% of the outstanding shares of the fund.

The fund may not:

1. Purchase any security (other than obligations of the U.S. government, its
agencies or instrumentalities), if as a result: (a) more than 25% of the value
of the fund's total assets would then be invested in securities of any single
issuer; or (b) as to 75% of the value of the fund's total assets, more than 5%
of the value of the fund's total assets would then be invested in securities of
any single issuer. For the purpose of this limitation, the fund will regard each
state and each political subdivision, agency or instrumentality of such state
and each multi-state agency of which such state is a member as a separate
issuer;

2. Borrow money, except from a bank for temporary or emergency purposes and not
for investment purposes, and then only in an amount not exceeding 5% of the
value of the fund's total assets at the time of borrowing;

3. Pledge, mortgage or hypothecate its assets, except that, to secure borrowings
permitted by subparagraph (2) above, it may pledge securities having a market
value at the time of pledge not exceeding 5% of the value of the fund's total
assets;

4. Knowingly purchase or otherwise acquire any securities which are subject to
legal or contractual restrictions on resale or which are not readily marketable,
or purchase the securities of any other investment company, except that it may
make purchases of securities of investment companies in accordance with its
investment objective, policies, and restrictions or as part of a merger,
consolidation or acquisition of assets;

5. Underwrite any issue of securities, except in connection with the purchase of
securities in accordance with its investment objective, policies and
limitations, or participate on a joint or joint-and-several basis in any
securities trading account;

6. Purchase or sell real estate (or real estate limited partnerships), but this
shall not prevent the fund from investing in Tax-Exempt Bonds or other permitted
obligations secured by real estate or interests therein;

7. Purchase or sell commodities or commodity contracts except options, financial
futures or options on financial futures contracts in accordance with its
investment objective, policies, and restrictions, or invest in oil, gas or other
mineral leases, exploration or development programs, or write or purchase puts,
calls, straddles, spreads or any combination thereof;

8. Make loans, except through the purchase of securities, including repurchase
agreements, in accordance with its investment objective, policies and
limitations;


                                       11
<PAGE>

9. Make short sales of securities or purchase any securities on margin, except
for such short-term credits as are necessary for the clearance of transactions
and margin payments in connection with options, financial futures contracts and
options on financial futures contracts; or

10. Purchase or retain the securities of any issuer other than the securities of
the fund, if, to the fund's knowledge, those officers and trustees of the fund,
or of the investment adviser or underwriter, who own individually or
beneficially more than 1/2 of 1% of the outstanding securities of such issuer
together own beneficially more than 5% of such outstanding securities.

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.


                                       15
<PAGE>


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 to
be paid by the fund: (a) charges and expenses for fund accounting, pricing and
appraisal services and related overhead, including, to the extent such services
are performed by personnel of 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. As compensation for its management services, the fund pays Pioneer
a 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% on assets over $300
million. This fee is normally computed and accrued daily and paid monthly.


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. See Appendix A for fees the fund paid to Pioneer for
administration and related 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


                                       16
<PAGE>

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 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. The fund, Pioneer and PFD have adopted a code
of ethics under Rule 17j-1 of the 1940 Act which is applicable to officers,
trustees/directors and designated employees. The code permits such persons to
engage in personal securities transactions for their own accounts, including
securities that may be purchased or held by the fund, and is designed to
prescribe means reasonably necessary to prevent conflicts of interest from
arising in connection with personal securities transactions. The code is on

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
non-U.S. 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.


                                       17

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.

The redemption price of shares of beneficial interest of the fund may, at
Pioneer's discretion, be paid in cash or portfolio securities. The fund has,
however, elected to be governed by Rule 18f-1 under the 1940 Act pursuant to
which the fund is obligated to redeem shares solely in cash up to the lesser of
$250,000 or 1% of the fund's net asset value during any 90-day period for any
one shareholder. Should the amount of redemptions by any shareholder exceed such
limitation, the fund will have the option of redeeming the excess in cash or
portfolio securities. In the latter case, the securities are taken at their
value employed in determining the fund's net asset value. A shareholder whose
shares are redeemed in-kind may incur brokerage charges in selling the
securities received in-kind. The selection of such securities will be made in
such manner as the Board of Trustees deems fair and reasonable.

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. 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. 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


                                       18
<PAGE>

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


                                       19
<PAGE>

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%


                                       20
<PAGE>

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 $33.00 for each Class A, Class B and Class C
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, the
fund's independent public accountants, provides 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.

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


                                       22
<PAGE>

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.

The Pioneer funds have entered into third-party brokerage and/or expense offset
arrangements to reduce the funds' total operating expenses. Pursuant to
third-party brokerage arrangements, certain of the funds that invest primarily
in U.S. equity securities may incur lower custody fees by directing brokerage to
third-party broker-dealers. Pursuant to expense offset arrangements, the funds
incur lower transfer agency expenses by maintaining their cash balances with the
custodian. 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


                                       23
<PAGE>

and certificates will not normally be issued. The fund reserves the right to
charge a fee for the issuance of Class A share certificates; certificates will
not be issued for Class B or Class C shares.


The fund's Agreement and Declaration of Trust, dated as of June 16, 1994 (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 three classes of
shares of the fund, designated as Class A shares, Class B shares and Class C
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


                                       24
<PAGE>

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 Trustee receives compensation for serving as
a trustee of the fund or other investment companies for which Pioneer acts as
investment adviser.

11.   SALES CHARGES

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.

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 gain 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


                                       26
<PAGE>

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 gain 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:


                                       27
<PAGE>


                                           CDSC as a % of Dollar
Year Since Purchase                       Amount Subject to CDSC

First                                               4.0
Second                                              4.0
Third                                               3.0
Fourth                                              3.0
Fifth                                               2.0
Sixth                                               1.0
Seventh and thereafter                              0.0


On March 31, 1999, in accordance with a tax-free reorganization approved by
shareholders of Pioneer Intermediate Tax-Free Fund, Pioneer Intermediate Tax-
Free Fund transferred all of its assets to the fund, and the fund assumed
Pioneer Intermediate Tax-Free Fund's liabilities. Class A, Class B and Class C
shares of the fund were issued proportionately to the respective holders of
shares of Pioneer Intermediate Tax-Free Fund on the reorganization date. Such
Class B shares redeemed within four years of purchase will be subject to a CDSC
at the rates shown in the table below.

                                            CDSC as a % of Dollar
Year Since Purchase                        Amount Subject to CDSC

First                                               3.0
Second                                              3.0
Third                                               2.0
Fourth                                              1.0
Fifth and thereafter                                0.0

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 (five years in the case of Class B shares
issued to former shareowners of Pioneer Intermediate Tax-Free Fund in connection
with the reorganization described above) 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 U.S. federal income 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.


                                       28
<PAGE>

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 gain 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 made 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.


Additional Payments to Dealers

From time to time, PFD or its affiliates may elect to make payments to dealers
in addition to the commissions described above. 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. 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. PFD will reallow to A.G. Edwards & Sons, Inc. the
entire sales charge for all sales of the fund's Class A shares to IRA accounts
if the order is placed from January 1, 2000 through April 17, 2000. PFD will
reallow to Citicorp Investment Services the entire sales charge for all sales of
the fund's Class A share if the order is placed from March 1, 2000 through June
30, 2000. PFD will reallow to participating broker/dealers the entire sales
charge for all sales of the fund's Class A shares if the order is placed from
March 1, 2000 through June 30, 2000. PFD or its affiliates may elect to pay
dealers an additional commission based on the net asset value of all of the
fund's Class B shares sold by a dealer during a particular period. PFD has
elected to pay dealers an amount equal to 0.50% of the net asset value of the
fund's Class B shares sold from April 1, 2000 through June 30, 2000. In
addition, at its own expense, PFD may elect to pay additional cash or other
incentives to dealers that sell or arrange for the sale of shares of the fund.
Such cash or other incentives may take the form of payment for attendance at
preapproved conferences or seminars, sales or training programs for invited
registered representatives and other employees, payment for travel expenses,
including lodging, incurred by registered representatives and other employees
for such seminars or training programs, seminars for the public, advertising and
preapproved sales campaigns or dealer-sponsored events. PFD may also elect to
make expense reimbursements for special training of a dealer's registered
representatives and other employees in group meetings or to help pay the
expenses of sales contests. PFD will offer such cash and other


                                       29
<PAGE>


incentives only to the extent permitted by applicable law or by a
self-regulatory agency such as the National Association of Securities Dealers,
Inc.

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 gain
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.

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


                                       30
<PAGE>

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. See the prospectus for more information. For personal assistance,
call 1-800-225-6292 between 8:00 a.m. and 9:00 p.m. Eastern time on weekdays.
Computer-assisted transactions may be available to shareholders who have
prerecorded certain bank information (see "FactFone(SM)"). 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.

FactFone(SM). FactFone(SM) is an automated inquiry and telephone transaction
system available to Pioneer mutual fund shareholders by dialing 1-800-225-4321.
FactFone(SM) 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 FactFone(SM) 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. 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
FactFone(SM). Call PSC for assistance.


                                       31
<PAGE>

FactFone(SM) 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 gain distributions on all Pioneer mutual funds.

Yields are calculated in accordance with SEC mandated standard formulas.

All performance numbers communicated through FactFone(SM) 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 and Class C 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.

In determining the value of the assets of the fund for the purpose of obtaining
the net asset value, securities for which reliable quotations are readily
available shall be valued on the basis of valuations furnished by pricing
services which utilize electronic data processing techniques to determine the
valuations for normal institutional-size trading units of such securities.
Securities not valued by the pricing service for which reliable quotations are
readily available, shall be valued at market values furnished by recognized
dealers in such securities. Short-term obligations with remaining maturities of
60 days or less shall be valued at amortized cost. Securities and other assets
for which reliable quotations are not readily available, shall be valued at
their fair value as determined in good faith under consistently applied
guidelines established by and under the general supervision of the Board of
Trustees of the fund, although the actual calculations may be made by persons
acting pursuant to the direction of the Board.

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


                                       32
<PAGE>

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 and Class C
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 U.S. federal income tax on income and capital gains distributed
to shareholders. If the fund did not qualify as a regulated investment company,
it would be treated as a U.S. corporation subject to U.S. 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 declares a dividend from any net investment income each business day.
Dividends are normally paid on the last business day of the month. The fund
distributes any net short- and long-term capital gains in November. Dividends
from income and/or capital gains may also be paid at such other times as may be
necessary for the fund to avoid U.S. 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, the character of income earned by certain entities in which the
fund invests that are not treated as corporations (e.g., partnerships or trusts)
for U.S. tax purposes will generally pass through to the fund. 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 U.S.
federal income tax purposes, all dividends are taxable 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 U.S. federal income tax purposes without regard to the length of time
the shareholder has held shares of the fund. The U.S. federal income tax status
of all distributions will be reported to shareholders annually.

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


                                       33
<PAGE>


If the fund acquires any equity interest (under future 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 that hold at least 50% of
their assets in investments producing such passive income ("passive foreign
investment companies"), the fund could be subject to U.S. federal income tax and
additional interest charges on "excess distributions" received from such
companies or on 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.

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 U.S. 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 U.S. 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 U.S. 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 with respect to 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.


                                       34

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 reinstatement 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
reinstatement 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 generally 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 of some capital gains and losses realized by the fund as
long-term or short-term. Certain options, futures and forward contracts relating
to foreign currency may be subject to Section 988, as described above, and
accordingly may 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 the fund may receive no
corresponding cash amounts, 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 capital 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


                                       35
<PAGE>


dividends-received deduction. The entire 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.

A state income (and possibly local income and/or intangible property) tax
exemption is generally available to the extent the fund's distributions are
derived from interest on (or, in the case of intangible property taxes, the
value of its assets is attributable to) certain U.S. government obligations,
provided in some states that certain thresholds for holdings of such obligations
and/or reporting requirements are satisfied. The fund will not seek to satisfy
any threshold or reporting requirements that may apply in particular taxing
jurisdictions, although the fund may in its sole discretion provide relevant
information to shareholders.

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 and 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 non-resident alien U.S. withholding tax at the rate of 30% or 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


                                       36
<PAGE>

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, yield or total return of the
fund's classes may be compared to averages or rankings prepared by Lipper, Inc.,
a widely recognized independent service which monitors mutual fund performance;
the Lehman Brothers Municipal Bond Index, an unmanaged measure of approximately
15,000 municipal bonds; or other comparable indices or investment vehicles.


In addition, the performance of the classes of the fund may be compared to
alternative investment or savings vehicles and/or to indices 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, 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.

Standardized Yield Quotations

The yield of a class is computed by dividing the class' net investment income
per share during a base period of 30 days, or one month, by the maximum offering
price per share of the class on the last day of such base period in accordance
with the following formula:


                                       37
<PAGE>

                               a-b
                  YIELD = 2[( ----- +1)^6-1]
                               cd
Where:

      a    =    interest earned during the period

      b    =    net expenses accrued for the period

      c    =    the average daily number of shares outstanding during the period
                that were entitled to receive dividends

      d    =    the maximum offering price per share on the last day of the
                period

For purposes of calculating interest earned on debt obligations as provided in
item "a" above:

(i) The yield to maturity of each obligation held by the fund is computed based
on the market value of the obligation (including actual accrued interest, if
any) at the close of business each day during the 30-day base period, or, with
respect to obligations purchased during the month, the purchase price (plus
actual accrued interest, if any) on settlement date, and with respect to
obligations sold during the month the sale price (plus actual accrued interest,
if any) between the trade and settlement dates.

(ii) The yield to maturity of each obligation is then divided by 360 and the
resulting quotient is multiplied by the market value of the obligation
(including actual accrued interest, if any) to determine the interest income on
the obligation for each day. The yield to maturity calculation has been made on
each obligation during the 30 day base period.

(iii) Interest earned on all debt obligations during the 30-day or one month
period is then totaled.

(iv) The maturity of an obligation with a call provision(s) is the next call
date on which the obligation reasonably may be expected to be called or, if
none, the maturity date.

With respect to the treatment of discount and premium on mortgage- or other
receivables-backed obligations which are expected to be subject to monthly
payments of principal and interest ("pay downs"), the fund accounts for gain or
loss attributable to actual monthly pay downs as an increase or decrease to
interest income during the period. In addition, the fund may elect (i) to
amortize the discount or premium remaining on a security, based on the cost of
the security, to the weighted average maturity date, if such information is
available, or to the remaining term of the security, if the weighted average
maturity date is not available, or (ii) not to amortize the remaining discount
or premium on a security.

For purposes of computing yield, interest income is recognized by accruing 1/360
of the stated interest rate of each obligation in the fund's portfolio each day
that the obligation is in the portfolio. Expenses of Class A and Class B accrued
during any base period, if any, pursuant to the respective Distribution Plans
are included among the expenses accrued during the base period.


                                       38
<PAGE>

See Appendix A for the standardized yield quotation for each class of fund
shares as of the most recently completed fiscal year.

Taxable Equivalent Yield

The fund may also from time to time advertise its taxable equivalent yield which
is determined by dividing that portion of the fund's yield (calculated as
described above) that is tax exempt by one minus the stated federal income tax
rate and adding the product to that portion, if any, of the fund's yield that is
not tax exempt.

See Appendix A for the taxable equivalent yield for each class of fund shares as
of the most recently completed fiscal year.

Standardized Average Annual Total Return Quotations

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.

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 = 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

     T       =   average annual total return


                                       39
<PAGE>

     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'
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(1)


Moody's Investors Service, Inc. ("Moody's") Short-Term 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.

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.

------------------
(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.


                                       45
<PAGE>

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.


                                       46
<PAGE>

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.

Moody's bond ratings, where specified, are applicable to financial contracts,
senior bank obligations and insurance company senior policyholder and claims
obligations with an original maturity in excess of one year. Obligations relying
upon support mechanisms such as letters-of-credit and bonds of indemnity are
excluded unless explicitly rated. 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 the 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 the actions of the
government controlling the currency of denomination. In addition, risk
associated with bilateral conflicts between an investor's home country and
either the issuer's home country or the country where an issuer branch is
located are not incorporated into Moody's ratings.

Moody's makes no representation that rated bank obligations or insurance company
obligations are exempt from registration under the Securities Act of 1933 or
issued in conformity with any other applicable law or regulation. Nor does
Moody's represent any specific bank or insurance company obligation is legally
enforceable or a valid senior obligation of a rated issuer.


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


                                       47
<PAGE>

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.


                                       48
<PAGE>

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.


                                       49
<PAGE>

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 inadequate 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: A subordinated debt or preferred stock obligation rated C is currently highly
vulnerable to nonpayment. The C rating may be used to cover a situation where a
bankruptcy petition has been filed or similar action taken, but payments on this
obligation are being continued. A C also will be assigned to a preferred stock
issue in arrears on dividends or sinking fund payments but that is currently
paying.

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 on an obligation 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 rating
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.

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 obligation as a matter of policy.

Local Currency and Foreign Currency Risks

Country risk considerations are a standard part of Standard & Poor's analysis
for credit ratings on any issuer or issue. Currency of repayment is a key factor
in this analysis. An obligor's capacity to repay foreign currency obligations
may be lower than its capacity to repay obligations in its local currency due to
the sovereign government's own relatively lower capacity to repay external
versus domestic debt. These sovereign risk considerations are incorporated in
the debt ratings assigned to specific issues. Foreign currency issuer ratings
are also distinguished from local currency issuer ratings to identify those
instances where sovereign risks make them different for the same issuer.

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 1,980 stocks ranging in market capitalization from $50 million to
$125 million. Index returns are calculated monthly.


Merrill Lynch High Yield Master II Index. This index is a market capitalization
weighted total return index covering U.S. dollar-denominated high-yield bonds.
Qualifying bonds must have at least $100 million par amount outstanding, a
remaining term to maturity greater than or equal to one year, and a credit
rating less than BBB3 but not in default (based on the composite of Moody's and
Standard & Poor's). The index includes deferred interest and pay-in-kind bonds,
but excludes structured notes, floating rate notes and other variable coupon
securities. The index also excludes emerging markets debt (issuers domiciled in
below investment grade rated countries). Index constituents are rebalanced
monthly on the last calendar day of the month. Index values are calculated
daily.


                                       54

Merrill Lynch Index of Convertible Bonds (Speculative Quality). This is a market
capitalization weighted index including all mandatory and non-mandatory domestic
corporate convertible securities with at least an original par of $50 million or
a $50 million market value; securities dropping below a market value of $40
million are excluded. Returns are calculated weekly based on Thursday's closing
prices and are linked monthly. All securities must be convertible to common
stock only. Quality range is D3-BB1 based on composite Moody's and Standard
& Poor's ratings.

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.


Morgan Stanley Capital International ("MSCI"). These indices are in U.S. dollar
terms with gross dividends reinvested and measure the performance of developed
and emerging stock markets around the world. MSCI All Country indices represent
both the developed and the emerging markets for a particular region. These
indices are unmanaged. The free indices exclude shares which are not readily
purchased by non-local investors. MSCI covers over 1,500 securities in 28
emerging markets and 2,300 securities in 23 developed markets, totaling over $20
trillion in market capitalization. Several Pioneer mutual funds that invest in
international securities compare their performance to various MSCI indices.




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.


                                       55
<PAGE>

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.


Lehman Brothers Government/Corporate Bond Index - Intermediate. This index is
comprised of securities with one to ten years to maturity. It includes Treasury
and government agency securities, investment-grade corporate bonds and Yankee
bonds.


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 $4.4 billion. The Russell
2500(TM) Index measures performance of the 2,500 smallest companies in the
Russell 3000. The average market capitalization is approximately $876 million,
and the largest company in the index has an approximate market capitalization of
$3.8 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 $1.3 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 $12.1
billion. The smallest company in the index has an approximate market
capitalization of $1.3 billion. The Russell Midcap(TM) Index measures
performance of the 800 smallest companies in the Russell 1000. The largest
company in the index has an approximate market capitalization of $11.2 billion.
The Russell 1000(R) Growth Index measures the performance of those Russell 1000
companies with higher price-to-



                                       56
<PAGE>


book ratios and higher forecasted growth values. The Russell 1000(R) Value Index
measures the performance of those Russell 1000 companies with lower
price-to-book ratios and lower forecasted growth values.

The Russell indexes are reconstituted annually as of June 30, based on May 31
market capitalizations.

Wilshire Real Estate Securities Index. The Wilshire Real Estate Securities Index
is a broad measure of the performance of publicly traded real estate securities,
such as REITs and real estate operating companies ("REOCs"). The index is
capitalization-weighted. As of March 31, 1999, 119 companies were included in
the index, with a total market cap of $116.97 billion. At September 30, 1999,
the companies in the index were 92.31% equity and hybrid REITs and 7.69% 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 Indexes. These indexes represent equally weighted performance, adjusted
for capital gain distributions and income dividends, of mutual funds that are
considered peers of the Pioneer mutual funds. Lipper, Inc. is an independent
firm that tracks mutual fund performance.


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.


Nasdaq Composite Index. The Nasdaq Composite Index measures all Nasdaq domestic
and non-U.S. based common stocks listed on The Nasdaq Stock Market. The index is
market-value weighted. The Nasdaq Composite includes over 5,000 companies and is
one of the most widely followed and quoted major market indices because it is so
broad-based.

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
June 16, 1994 (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


                                      C-1
<PAGE>


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
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
