BASIC INFORMATION ABOUT THE FUND

INVESTMENT OBJECTIVE

To provide current income from an investment grade portfolio with due regard to
preservation of capital and prudent investment risk. The fund also seeks a
relatively stable level of dividends; however, the level of dividends will be
maintained only if consistent with preserving the investment grade quality of
the fund's portfolio.

INVESTMENT STRATEGIES

The fund invests primarily in:

[square bullet]  debt securities issued or guaranteed by the U.S. government or
                 its agencies and instrumentalities,
[square bullet]  debt securities, including convertible debt securities, of 
                 corporate and other issuers rated at least investment grade at
                 the time of investment, and comparably rated commercial paper,
[square bullet]  cash and cash equivalents, certificates of deposit, repurchase
                 agreements maturing in one week or less and bankers'
                 acceptances.

Normally, the fund invests at least 80% of its total assets in these securities.

The fund's investments may have all types of interest rate payment and reset
terms, including fixed rate, zero coupon, contingent, deferred and payment in
kind and auction rate features. The fund invests in securities with a broad
range of maturities and maintains an average portfolio maturity which varies
based upon the judgement of Pioneer.

[BEGIN SIDEBAR]
[SOLID BOX]
- --------------------------------------------------------------------------------
INVESTMENT GRADE DEBT SECURITIES
- --------------------------------------------------------------------------------
A debt security is considered investment grade if it is:
o rated BBB or higher at the time of purchase by Standard & Poor's Rating Group
o rated the equivalent rating by a nationally recognized securities rating
  organization or
o determined to be of equivalent credit quality by Pioneer.
- --------------------------------------------------------------------------------
[END SIDEBAR]

The fund may invest a substantial portion of its assets in mortgage-related
securities, which represent interests in pools of mortgage loans assembled for
sale to investors by various U.S. governmental agencies, government-related
organizations and private issuers. These investments may include
mortgage-related derivative securities such as collateralized mortgage
obligations (CMOs). The holder of an interest in a collateralized mortgage
obligation is entitled to receive specified cash flows from a pool of mortgages.
Depending upon the category of collateralized mortgage obligation purchased, the
holder may be entitled to payment before the cash flow from the pool is used to
fund other collateralized mortgage obligations or, alternatively, the holder may
be paid only after the cash flow has been used to fund other collateralized
mortgage obligations first.

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

PRINCIPAL RISKS OF INVESTING IN THE FUND

Even though the fund seeks to provide current income, you could lose money on
your investment, or the fund could fail to generate current income, if:

[square bullet]  Interest rates go up, causing the value of the fund's
                 investments to decline.
[square bullet]  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.
[square bullet}  During periods of declining interest rates, the issuer of a
                 security may exercise its option to prepay principal earlier
                 than scheduled, forcing the fund to reinvest in lower
                 yielding securities. This is known as call or prepayment risk.
[square bullet]  During periods of rising interest rates, the average life of
                 certain types of securities may be extended because of slower
                 than expected principal payments. This may lock in a below 
                 market interest rate, increase the security's duration and
                 reduce the value of the security. This is known as extension
                 risk.
[square bullet]  Pioneer's judgment about the attractiveness, relative value or
                 potential appreciation of a particular sector, security or
                 hedging strategy proves to be incorrect.
<PAGE>
To the extent the fund invests significantly in mortgage-related securities, its
exposure to prepayment and extension risks may be greater than if it invested in
other fixed income securities. Mortgage derivatives held by the fund may have
especially volatile prices and may have a disproportionate effect on the fund's
share price.

EXAMPLE

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

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

          If you sell your shares                 If you do not sell your shares

                           Number of years you own your shares

OTHER INVESTMENT POLICIES
As discussed, the fund invests primarily in a broad range of investment grade
debt securities to provide current income with due regard for preservation of
capital and prudent investment risk.

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).

ADDITIONAL INFORMATION ABOUT DEBT SECURITIES
U.S. government securities include U.S. Treasury obligations, such as bills,
bonds and notes, and obligations issued or guaranteed by U.S. government
agencies or instrumentalities. These obligations may be supported by:

[square bullet]  the full faith and credit of the U.S. Treasury, such as
                 securities issued by the Government National Mortgage 
                 Association (GNMA);
[square bullet]  the authority of the U.S. government to purchase certain
                 obligations of the issuer, such as securities issued by the
                 Federal National Mortgage Association (FNMA),
[square bullet]  the limited authority of the issuer to borrow from the U.S.
                 Treasury, such as securities issued by the Student Loan
                 Marketing Association; or
[square bullet]  only the credit of the issuer.

Certain debt instruments may only pay principal at maturity or may only
represent the right to receive payments of principal or payments of interest on
underlying pools of mortgage or government securities, but not both. The value
of these types of instruments may change more drastically than debt securities
that pay both principal and interest during periods of changing interest rates.
Principal only mortgage backed securities are particularly subject to prepayment
risk. Interest only instruments are particularly subject to extension risk. For
mortgage derivatives and structured securities that have imbedded leverage
features, small changes in interest or prepayment rates may cause large and
sudden price movements. Mortgage derivatives can also become illiquid and hard
to value in declining markets.

For purposes of the fund's credit quality policies, if a security receives
different ratings from nationally recognized rating organizations, the fund will
use the highest rate assigned to that security.

INVESTMENTS IN BELOW INVESTMENT GRADE SECURITIES
The fund may invest up to 20% of its total assets in debt securities rated below
investment grade or, if unrated, of equivalent quality as determined by Pioneer.
Debt securities rated below investment grade are commonly referred to as "junk
bonds" and are considered speculative. Below investment grade debt securities
involve greater risk of loss, are subject to greater price volatility and are
less liquid, especially during periods of economic uncertainty or change, than
higher quality debt securities.

INVESTMENTS IN NON-U.S. SECURITIES
The fund may invest in securities of Canadian issuers to the same extent as
securities of U.S. issuers. The fund may invest up to 15% of its total assets
(at the time of purchase) in equity and debt securities of non-U.S. issuers. The
fund will not invest more than 5% of its total assets (at the time of purchase)
in the securities of emerging markets issuers. Investing in non-U.S. issuers may
involve unique risks compared to investing in securities of U.S. issuers. These
risks may include:

[Square bullet]  Less information about non-U.S. issuers or markets may be
                 available due to less rigorous disclosure and accounting
                 standards or regulatory practices
[Square bullet]  Many non-U.S. markets are smaller, less liquid and more
                 volatile. In a changing market, Pioneer may not be able to sell
                 the fund's portfolio securities in amounts and at prices it
                 considers reasonable
[Square bullet]  Adverse effect of currency exchange rates or controls on the
                 value of the fund's investments
[Square bullet]  Political, economic and social developments that adversely 
                 affect the securities markets
[Square bullet]  Withholding and other non-U.S. taxes may decrease the
                 fund's return

TEMPORARY INVESTMENTS
Normally, the fund invests substantially all of its assets to meet its
investment objective. The fund may invest the remainder of its assets in
securities with a remaining maturity of less than one year, cash equivalents or
may hold cash. For temporary defensive purposes, the fund may depart from its
principal investment strategies and invest part or all of its assets in these
securities. During these 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 incur a higher level of taxable income or capital
gains.

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

[Square bullet]  As a hedge against adverse changes in interest rates or
                 currency exchange rates
[Square bullet]  As a substitute for purchasing or selling securities
[Square bullet]  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 or currency exchange rates. If changes in a
derivative's value do not correspond to changes in the value of the fund's other
investments, the fund may not fully benefit from or could lose money on the
derivative position. In addition, some derivatives involve risk of loss if the
person who issued the derivative defaults on its obligation. Certain derivatives
may be less liquid and more difficult to value.

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

PIONEER GROUP
The Pioneer Group, Inc. and its subsidiaries are engaged in financial services
businesses in the United States and many foreign countries. As of December 31,
1998, the firm had more than $23 billion in assets under management worldwide
including more than $22 billion in U.S. mutual funds. The firm's U.S. mutual
fund investment history includes creating 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 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. 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.

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

Share price

The net asset value
per share calculated
on the day of your 
transaction, 
adjusted for any 
applicable sales 
charge, is often 
referred to as the 
share price.
- ---------------------
[end sidebar text]


Net asset value

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

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

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


Choosing a class of shares

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

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

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

Distribution plans

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

Sales charges: Class A shares

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

Investments of $1 million or more

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

Reduced sales charges

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

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

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:

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

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

available to:

Group Plans if the sponsoring organization

[square bullet] recommends purchases of Pioneer mutual funds to,

[square bullet] permits solicitation of, or

[square bullet] facilitates purchases by,

Letter of intent (Class A)

You can use a letter of intent to qualify for reduced sales charges in two
situations:

[square bullet] If you plan to invest at least $50,000 (excluding any
                reinvestment of dividends and capital gain distributions) in the

[square bullet] 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:

[square bullet] Your investment firm must have a sales agreement with the
                distributor;
[square bullet] 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;
[square bullet] You paid a sales charge on the original purchase of the shares
                sold; and

                value purchases to shareowners that sell shares of a Pioneer
                mutual fund.

Waiver or reduction of contingent deferred sales charges (CDSC)

Class A shares that are subject to a CDSC

Purchases of Class A shares of $1 million or more, or by participants in a Group
Plan which were not subject to an initial sales charge, may be subject to a CDSC
upon redemption. A CDSC is payable to the distributor in the event of a share
redemption within 12 months following the share purchase, at the rate of 1% of
the lesser of the value of the shares redeemed (exclusive of reinvested dividend
and capital gain distributions) or the total cost of such shares. However, the
CDSC is waived for redemptions of Class A shares purchased by an
employer-sponsored retirement plan qualified under Section 401 of the Internal
Revenue Code that has 1,000 or more eligible employees or at least $10 million
in plan assets.


Class A, Class B and Class C shares

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

[square bullet] The distribution results from the death of all registered
                account owners or a participant in an employer-sponsored plan.
                For UGMAs, UTMAs and trust accounts, the waiver applies only
                upon the death of all beneficial owners;
[square bullet] The distribution results from a total and permanent disability
                (as defined by Section 72 of the Internal Revenue Code)
                occurring after the purchase of the shares being sold. For
                UGMAs, UTMAs and trust accounts, the waiver only applies upon
                the disability of all beneficial owners;
[square bullet] 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);
[square bullet] The distribution is from any type of IRA, 403(b) or
                employer-sponsored plan and one of the following applies:

                - It is part of a series of substantially equal periodic

General rules on buying, exchanging and selling
your fund shares


Share price

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


Buying

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

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


Minimum investment amounts

Your initial investment must be at least $1,000. Additional investments must be
at least $50 for Class A shares and $500 for Class B or Class C shares. You may
qualify for lower initial or subsequent investment minimums if you are opening a
retirement plan account, establishing an automatic investment plan or placing
your trade through your investment firm.


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

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

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

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

<PAGE>


Exchanging

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

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

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


Selling

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

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

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

Buying, exchanging and selling shares



Account options

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


Automatic investment plans

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


Pioneer Investomatic Plan

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

Automatic exchanges

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

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


Distribution options

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

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

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

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

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

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

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:

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

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


Direct deposit

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

Voluntary tax withholding

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

Reinstatement privilege for Class A shares

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

                                                                              23

Shareowner account policies


Signature guarantees and other requirements

You are required to obtain a signature guarantee when you are:

[square bullet]  Requesting certain types of exchanges or sales of fund shares
[square bullet]  Redeeming shares for which you hold a share certificate
[square bullet]  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.

Minimum account size

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


Telephone access

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


Share certificates

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

                                                                              25

Dividends, capital gains and taxes



[begin sidebar text]
- --------------------
[solid box]

Sales and 
exchanges may be 
taxable transactions
to shareowners.
- --------------------
[end sidebar text]


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
the date of sale. Dividends are normally paid on the last business day of each
month. The fund makes distributions from long-term capital gains, if any,
annually, generally in November.


The fund may also pay dividends and distributions at other times if necessary
for the fund to avoid federal income or excise tax. If you invest in the fund
close to the time that the fund makes a capital gains distribution, generally
you will pay a higher price per share and you will pay taxes on the amount of
the capital gains distribution whether you reinvest the distribution or receive
it as cash.

Taxes

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

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

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

Financial highlights



The financial highlights table helps you understand the fund's
financial performance for the past five years.

Certain information reflects financial results for a single fund share. The
total returns in the table represent the rate that you would have earned on an
investment in the fund (assuming reinvestment of all dividends and
distributions).

This information has been audited by Arthur Andersen LLP, whose reports are
included in the fund's annual and semiannual reports along with the fund's
financial statements. The annual and semiannual reports are available upon
request.

1.       FUND HISTORY

The fund is a diversified open-end management investment company. The fund was
originally organized as a Massachusetts corporation on August 16, 1978,
reorganized as a Massachusetts business trust on December 31, 1985 and
reorganized as any Delaware business trust on May 17, 1999.

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. Accordingly, any
later increase or decrease resulting from a change in values, net assets or
other circumstances will not be considered in determining whether the investment
complies with the fund's restrictions and policies.

PRIMARY INVESTMENTS

Under normal circumstances, at least 80% of the fund's total assets must be
invested in (a) debt securities issued or guaranteed by the U.S. Government or
its agencies or instrumentalities, (b) debt securities, including convertible
securities, of corporate and other issuers rated at least investment grade at
the time of investment, and (c) cash and cash equivalents, such as certificates
of deposit, repurchase agreements maturing in one week or less and bankers'
acceptances.

DEBT SECURITIES RATING CRITERIA

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

The fund may not invest more than 20% of its total assets in below investment
grade debt securities. Below investment grade debt securities are those rated
"BB" and below by Standard & Poor's or the equivalent rating of other national
statistical rating organizations. See Appendix B for a description of rating
categories.

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

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

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

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

U.S. GOVERNMENT SECURITIES

U.S. government securities in which the fund invests 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.

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.

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 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.

MORTGAGE-BACKED SECURITIES

The fund may invest in mortgage pass-through certificates and multiple-class
pass-through securities, such as real estate mortgage investment conduits
("REMIC") pass-through certificates, collateralized mortgage obligations
("CMOs") and stripped mortgage-backed securities ("SMBS"), and other types of
"mortgage-backed securities" that may be available in the future. A
mortgage-backed security is an obligation of the issuer backed by a mortgage or
pool of mortgages or a direct interest in an underlying pool of mortgages. Some
mortgage-backed securities, such as CMOs, make payments of both principal and
interest at a variety of intervals; others make semiannual interest payments at
a predetermined rate and repay principal at maturity (like a typical bond).
Mortgage-backed securities are based on different types of mortgages including
those on commercial real estate or residential properties. Mortgage-backed
securities often have stated maturities of up to thirty years when they are
issued, depending upon the length of the mortgages underlying the securities. In
practice, however, unscheduled or early payments of principal and interest on
the underlying mortgages may make the securities' effective maturity shorter
than this, and the prevailing interest rates may be higher or lower than the
current yield of the fund's portfolio at the time the fund receives the payments
for reinvestment. Mortgage-backed securities may have less potential for capital
appreciation than comparable fixed income securities, due to the likelihood of
increased prepayments of mortgages as interest rates decline. If the fund buys
mortgage-backed securities at a premium, mortgage foreclosures and prepayments
of principal by mortgagors (which may be made at any time without penalty) may
result in some loss of the fund's principal investment to the extent of the
premium paid.

The value of mortgage-backed securities may also change due to shifts in the
market's perception of issuers. In addition, regulatory or tax changes may
adversely affect the mortgage securities markets as a whole. Non-governmental
mortgage-backed securities may offer higher yields than those issued by
government entities, but also may be subject to greater price changes than
governmental issues.

GUARANTEED MORTGAGE PASS-THROUGH SECURITIES. Guaranteed mortgage pass-through
securities represent participation interests in pools of residential mortgage
loans and are issued by U.S. Governmental or private lenders and guaranteed by
the U.S. Government or one of its agencies or instrumentalities, including but
not limited to GNMA, FNMA and FHLMC. GNMA certificates are guaranteed by the
full faith and credit of the U.S. government for timely payment of principal and
interest on the certificates. FNMA certificates are guaranteed by FNMA, a
federally chartered and privately owned corporation, for full and timely payment
of principal and interest on the certificates. FHLMC certificates are guaranteed
by FHLMC, a corporate instrumentality of the U.S. government, for timely payment
of interest and the ultimate collection of all principal of the related mortgage
loans.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through pools of conventional residential mortgage loans. Such issuers may,
in addition, be the originators and/or servicers of the underlying mortgage
loans as well as the guarantors of the mortgage-related securities. Because
there are no direct or indirect government or agency guarantees of payments in
pools created by such non-governmental issuers, they generally offer a higher
rate of interest than government and government-related pools. Timely payment of
interest and principal of these pools may be supported by insurance or
guarantees, including individual loan, title, pool and hazard insurance and
letters of credit. The insurance and guarantees are issued by governmental
entities, private insurers and the mortgage poolers. There can be no assurance
that the private insurers or guarantors can meet their obligations under the
insurance policies or guarantee arrangements.

Mortgage-related securities without insurance or guarantees may be purchased if
Pioneer determines that the securities meet the fund's quality standards.
Mortgage-related securities issued by certain private organizations may not be
readily marketable.

MULTIPLE-CLASS PASS-THROUGH SECURITIES AND COLLATERALIZED MORTGAGE OBLIGATIONS.
CMOs and REMIC pass-through or participation certificates may be issued by,
among others, U.S. government agencies and instrumentalities as well as private
issuers. REMICs are CMO vehicles that qualify for special tax treatment under
the Internal Revenue Code of 1986, as amended (the "Code") and invest in
mortgages principally secured by interests in real property and other
investments permitted by the Code. CMOs and REMIC certificates are issued in
multiple classes and the principal of and interest on the mortgage assets may be
allocated among the several classes of CMOs or REMIC certificates in various
ways. Each class of CMOs or REMIC certificates, often referred to as a
"tranche," is issued at a specific adjustable or fixed interest rate and must be
fully retired no later than its final distribution date. Generally, interest is
paid or accrues on all classes of CMOs or REMIC certificates on a monthly basis.

Typically, CMOs are collateralized by GNMA, FNMA or FHLMC certificates but also
may be collateralized by other mortgage assets such as whole loans or private
mortgage pass-through securities. Debt service on CMOs is provided from payments
of principal and interest on collateral of mortgaged assets and any reinvestment
income thereon.

STRIPPED MORTGAGE-BACKED SECURITIES. SMBS are multiple-class mortgage-backed
securities that are created when a U.S. government agency or a financial
institution separates the interest and principal components of a mortgage-backed
security and sells them as individual securities. The fund only invests SMBS
that are usually structured with two classes that receive different proportions
of interest and principal distributions on a pool of mortgage assets. A typical
SMBS will have one class receiving some of the interest and most of the
principal, while the other class will receive most of the interest and the
remaining principal. The holder of the "principal-only" security (PO) receives
the principal payments made by the underlying mortgage-backed security, while
the holder of the "interest-only" security (IO) receives interest payments from
the same underlying security. The prices of stripped mortgage-backed securities
may be particularly affected by changes in interest rates. As interest rates
fall, prepayment rates tend to increase, which tends to reduce prices of IOs and
increase prices of POs. Rising interest rates can have the opposite effect.
Although the market for these securities is increasingly liquid, Pioneer may
determine that certain stripped mortgage-backed securities issued by the U.S.
government, its agencies or instrumentalities are not readily marketable. If so,
these securities, together with privately-issued stripped mortgage-backed
securities, will be considered illiquid for purposes of the fund's limitation on
investments in illiquid securities. The yields and market risk of interest only
and principal only SMBS, respectively, may be more volatile than those of other
fixed income securities.

The fund also may invest in planned amortization class ("PAC") and target
amortization class ("TAC") CMO bonds which involve less exposure to prepayment,
extension and interest rate risks than other mortgage-backed securities,
provided that prepayment rates remain within expected prepayment ranges or
"collars." To the extent that the prepayment rates remain within these
prepayment ranges, the residual or support tranches of PAC and TAC CMOs assume
the extra prepayment, extension and interest rate risks associated with the
underlying mortgage assets.

RISK FACTORS ASSOCIATED WITH MORTGAGE-BACKED SECURITIES. Investing in
mortgage-backed securities involves certain risks, including the failure of a
counterparty to meet its commitments, adverse interest rate changes and the
effects of prepayments on mortgage cash flows. In addition, investing in the
lowest tranche of CMOs and REMIC certificates involves risks similar to those
associated with investing in equity securities. However, due to adverse tax
consequences under current tax laws, the fund does not intend to acquire
"residual" interests in REMICs. Further, the yield characteristics of
mortgage-backed securities differ from those of traditional fixed income
securities. The major differences typically include more frequent interest and
principal payments (usually monthly), the adjustability of interest rates of the
underlying instrument, and the possibility that prepayments of principal may be
made substantially earlier than their final distribution dates.

Prepayment rates are influenced by changes in current interest rates and a
variety of economic, geographic, social and other factors and cannot be
predicted with certainty. Both adjustable rate mortgage loans and fixed rate
mortgage loans may be subject to a greater rate of principal prepayments in a
declining interest rate environment and to a lesser rate of principal
prepayments in an increasing interest rate environment. Under certain interest
rate and prepayment rate scenarios, the fund may fail to recoup fully its
investment in mortgage-backed securities notwithstanding any direct or indirect
governmental, agency or other guarantee. When the fund reinvests amounts
representing payments and unscheduled prepayments of principal, it may obtain a
rate of interest that is lower than the rate on existing adjustable rate
mortgage pass-through securities. Thus, mortgage-backed securities, and
adjustable rate mortgage pass-through securities in particular, may be less
effective than other types of U.S. government securities as a means of "locking
in" interest rates.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

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

WARRANTS

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

PREFERRED SHARES

The fund may invest in preferred shares of beneficial interest of trust
instruments. Preferred shares are equity securities, but they have many
characteristics of fixed income securities, such as a fixed dividend payment
rate and/or a liquidity preference over the issuer's common shares. However,
because preferred shares are equity securities, they may be more susceptible to
risks traditionally associated with equity investments than the fund's fixed
income securities.

ILLIQUID SECURITIES

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

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

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

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

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

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

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.

DEBT OBLIGATIONS OF FOREIGN GOVERNMENTS

An investment in debt obligations of foreign governments and their political
subdivisions (sovereign debt) involve special risks that are not present in
corporate debt obligations. The foreign issuer of the sovereign debt or the
foreign governmental authorities that control the repayment of the debt may be
unable or unwilling to repay principal or interest when due, and a fund may have
limited recourse in the event of a default. During periods of economic
uncertainty, the market prices of sovereign debt may be more volatile than
prices of debt obligations of U.S. issues. In the past, certain foreign
countries have encountered difficulties in servicing their debt obligations,
withheld payments of principal and interest and declared moratoria on the
payment of principal and interest on their sovereign debt.

A sovereign debtor's willingness or ability to repay principal and pay interest
in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign currency reserves, the availability of
sufficient foreign exchange, the relative size of the debt service burden, the
sovereign debtor's policy toward its principal international lenders and local
political constraints. Sovereign debtors may also be dependent on expected
disbursements from foreign governments, multilateral agencies and other entities
to reduce principal and interest arrearages on their debt. The failure of a
sovereign debtor to implement economic reforms, achieve specified levels of
economic performance or repay principal or interest when due may result in the
cancellation of third-party commitments to lend funds to the sovereign debtor,
which may further impair such debtor's ability or willingness to service its
debts.

EURODOLLAR INSTRUMENTS AND SAMURAI AND YANKEE BONDS. The fund may invest in
Eurodollar instruments and Samurai and Yankee bonds. Eurodollar instruments are
bonds of corporate and government issuers that pay interest and principal in
U.S. dollars but are issued in markets outside the United States, primarily in
Europe. Samurai bonds are yen-denominated bonds sold in Japan by non-Japanese
issuers. Yankee bonds are U.S. dollar denominated bonds typically issued in the
U.S. by foreign governments and their agencies and foreign banks and
corporations. The fund may also invest in Eurodollar Certificates of Deposit
("ECDs"), Eurodollar Time Deposits ("ETDs") and Yankee Certificates of Deposit
("Yankee CDs"). ECDs are U.S. dollar-denominated certificates of deposit issued
by foreign branches of domestic banks; ETDs are U.S. dollar-denominated deposits
in a foreign branch of a U.S. bank or in a foreign bank; and Yankee CDs are U.S.
dollar-denominated certificates of deposit issued by a U.S. branch of a foreign
bank and held in the U.S. These investments involve risks that are different
from investments in securities issued by U.S. issuers, including potential
unfavorable political and economic developments, foreign withholding or other
taxes, seizure of foreign deposits, currency controls, interest limitations or
other governmental restrictions which might affect payment of principal or
interest.

RISKS OF NON-U.S. INVESTMENTS

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

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

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

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

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

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

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

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

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

OPTIONS ON SECURITIES AND SECURITIES INDICES

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

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

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

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

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

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

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

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

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

Reasons for the absence of a liquid secondary market on an exchange include the
following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the Options Clearing Corporation (the "OCC")
may not at all times be adequate to handle current trading volume; or (vi) one
or more exchanges could, for economic or other reasons, decide or be compelled
at some future date to discontinue the trading of options (or a particular class
or series of options), in which event the secondary market on that exchange (or
in that class or series of options) would cease to exist, although outstanding
options on that exchange, if any, that had been issued by the OCC as a result of
trades on that exchange would continue to be exercisable in accordance with
their terms. The fund may terminate its obligations under an exchange-traded
call or put option by purchasing an option identical to the one it has written.
Obligations under over-the-counter options may be terminated only by entering
into an offsetting transaction with the counterparty to such option. Such
purchases are referred to as "closing purchase transactions."

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

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

The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The successful use of protective
puts for hedging purposes depends in part on Pioneer's ability to predict future
price fluctuations and the degree of correlation between the options and
securities markets.

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

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

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

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

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

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

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

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

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

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

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

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

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

Futures contracts and related options involve brokerage costs, require margin
deposits and, in the case of contracts and options obligating the fund to
purchase securities or currencies, require the fund to segregate assets to cover
such contracts and options.

While transactions in futures contracts and options on futures may reduce
certain risks, such transactions themselves entail certain other risks. Thus,
while the fund may benefit from the use of futures and options on futures,
unanticipated changes in interest rates, securities prices or currency exchange
rates may result in a poorer overall performance for the fund than if it had not
entered into any futures contracts or options transactions. In the event of an
imperfect correlation between a futures position and a portfolio position which
is intended to be protected, the desired protection may not be obtained and the
fund may be exposed to risk of loss. It is not possible to hedge fully or
perfectly against the effect of currency fluctuations on the value of foreign
securities because currency movements impact the value of different securities
in differing degrees.

FOREIGN CURRENCY TRANSACTIONS

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

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

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

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

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

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

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

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

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

OPTIONS ON FOREIGN CURRENCIES

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

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

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

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

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

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

The fund may also use options on currencies to cross-hedge, which involves
writing or purchasing options on one currency to hedge against changes in
exchange rates of a different currency with a pattern of correlation. Cross
hedging may also include using a foreign currency as a proxy for the U.S.
dollar, if Pioneer determines that there is a pattern of correlation between
that currency and the U.S. dollar.

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

ECONOMIC MONETARY UNION (EMU)

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

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

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, to a limited extent, non-U.S.
currency. The fund's investment in commercial bank obligations include
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. The fund may also invest in variable amount
master demand notes (which is a type of commercial paper) which represents a
direct borrowing arrangement involving periodically fluctuating rates of
interest under a letter agreement between a commercial paper issuer and an
institutional lender, pursuant to which the lender may determine to invest
varying amounts. Transfer of such notes is usually restricted by the issuer, and
there is no secondary trading market for such notes. To the extent the fund
invests in master demand notes, these investments will be included in the fund's
limitation on illiquid securities.

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.

PORTFOLIO TURNOVER

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

INVESTMENT RESTRICTIONS

FUNDAMENTAL INVESTMENT RESTRICTIONS. The fund has adopted certain fundamental
investment restrictions which may not be changed without the affirmative vote of
the holders of a majority of the fund's outstanding voting securities. As used
in the prospectus and this SAI, such approval means the approval of the lesser

investment company under the 1940 Act.

(2) Invest 25% or more of its total assets in the securities of one or more
issuers (excluding the U.S. government or its agencies or instrumentalities)
conducting their principal business activities in the same industry. For
purposes of this restriction the electric utility, natural gas utility, and
telephone industries shall be considered separate industries.

(3) Invest in real estate, except that the fund may invest in securities of
issuers that invest in real estate or interests therein, securities that are
secured by real estate or interests therein, securities of real estate
investment trusts and mortgage-backed securities.

(4) Invest in commodities or commodity contracts, except that the fund may
invest in currency instruments and contracts and financial instruments and
contracts that might be deemed to be commodities and commodity contracts.

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

(6) Make loans, except by the purchase of debt obligations, by entering into
repurchase agreements or through the lending of portfolio securities.

borrow up to an additional 5% of the fund's assets for temporary purposes; (c)
obtain such short-term credits as are necessary for the clearance of portfolio
transactions; (d) purchase securities on margin to the extent permitted by
applicable law; and (e) engage in transactions in mortgage dollar rolls that are
accounted for as financings.

NON-FUNDAMENTAL INVESTMENT RESTRICTIONS. The following restriction has been
designated as non-fundamental and may be changed by a vote of the fund's Board
of Trustees without approval of shareholders.

The fund may not:

(a) invest in companies for the purpose of exercising control or management;

(b) Purchase securities while borrowings are in excess of 5% of total assets.

SHARE OWNERSHIP

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

COMPENSATION OF OFFICERS AND TRUSTEES

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

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

4.       INVESTMENT ADVISER

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

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

Under the terms of its contract with the fund, Pioneer pays all the operating
expenses, including executive salaries and the rental of office space, relating
to its services for the fund, with the exception of the following, which are 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) any 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 to the expenses described above, the fund
shall pay 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 and expenses incurred,
Pioneer is entitled to an annual fee at the rate of 0.50% of the fund's average
daily net assets. This fee is computed 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.

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

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

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

5.        PRINCIPAL UNDERWRITER AND DISTRIBUTION PLANS

PRINCIPAL UNDERWRITER

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

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

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

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

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

DISTRIBUTION PLANS

The fund has adopted a plan of distribution pursuant to Rule 12b-1 under the
1940 Act with respect to its Class A shares (the "Class A Plan") and 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. Banks are currently prohibited under the Glass-Steagall
Act from providing certain underwriting or distribution services. If a bank is
prohibited from acting in any capacity or providing any of the described
services, management will consider what action, if any, would be appropriate.
The expenses of the fund pursuant to the Class A Plan are accrued daily at a
rate which may not exceed the annual rate of 0.25% of the fund's average daily
net assets attributable to Class A shares. Distribution expenses of PFD are
expected to substantially exceed the distribution fees paid by the fund in a
given year.

The Class A Plan does not provide for the carryover of reimbursable expenses
beyond 12 months from the time the fund is first invoiced for an expense. The
limited carryover provision in the Class A Plan may result in an expense
invoiced to the fund in one fiscal year being paid in the subsequent fiscal year
and thus being treated for purposes of calculating the maximum expenditures of
the fund as having been incurred in the subsequent fiscal year. In the event of
termination or non-continuance of the Class A Plan, the fund has 12 months to
reimburse any expense which it incurs prior to such termination or
non-continuance, provided that payments by the fund during such 12-month period
shall not exceed 0.25% of the fund's average daily net assets attributable to
Class A shares during such period. See Appendix A for the amount, if any, of
carryover of distribution expenses as of the end of the most recent calendar
year.

CLASS B PLAN. Commissions on the sale of Class B shares equal to 4.00% 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 permit PFD to sell its right to
receive distribution fees under the Class B Plan and CDSCs to third parties. PFD
enters into such transactions to finance the payment of commissions to brokers
at the time of sale and other distribution-related expenses. In connection with
such amendments, the fund has agreed that the distribution fee will not be
terminated or modified (including a modification by change in the rules relating
to the conversion of Class B shares into Class A shares) with respect to Class B
shares (a) issued prior to the date of any termination or modification or (b)
attributable to Class B shares issued through one or a series of exchanges of
shares of another investment company for which PFD acts as principal underwriter
which were initially issued prior to the date of such termination or
modification or (c) issued as a dividend or distribution upon Class B shares
initially issued or attributable to Class B shares issued prior to the date of
any such termination or modification except:

         (i) to the extent required by a change in the 1940 Act, the rules or
regulations under the 1940 Act, the Conduct Rules of the NASD or an order of any
court or governmental agency;

         (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, 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.

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

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

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

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

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

Each Plan's adoption, terms, continuance and termination are governed by Rule
12b-1 under the 1940 Act. The Board of Trustees believes that there is a
reasonable likelihood that the Plans will benefit the fund and its current and
future shareholders. The Plans may not be amended to increase materially the
annual percentage limitation of average net assets which may be spent for the
services described therein without approval of the shareholders of the fund
affected thereby, and material amendments of the Plans must also be approved by
the Trustees as provided in Rule 12b-1.

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

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

6.       SHAREHOLDER SERVICING/TRANSFER AGENT

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

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

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

7.       CUSTODIAN

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

8.       INDEPENDENT PUBLIC ACCOUNTANTS

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

9.       PORTFOLIO TRANSACTIONS

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

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

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

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

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

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

10.      DESCRIPTION OF SHARES

As an open-end management investment company, the fund continuously offers its
shares to the public and under normal conditions must redeem its shares upon the
demand of any shareholder at the next determined net asset value per share less
any applicable CDSC. See "Sales Charges." When issued and paid for in accordance
with the terms of the prospectus and statement of additional information, shares
of the fund are fully paid and non-assessable. Shares will remain on deposit
with the fund's transfer agent and certificates will not normally be issued. The
fund reserves the right to charge a fee for the issuance of Class A share
certificates; certificates will not be issued for Class B, Class C or Class Y
shares.

The fund's Agreement and Declaration of Trust, dated as of [BOLD] January 5,
1999 (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 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 Trustees who is not an "interested person" of
Pioneer shall be considered to be independent for purposes of Delaware law
notwithstanding the fact that such trustees receive compensation for serving as
a trustee of the fund or other investment companies for which Pioneer acts as
investment adviser.

11.      SALES CHARGES

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

CLASS A SHARE SALES CHARGES

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

                  .........                   SALES CHARGE AS A % OF
                                              ----------------------
                  .........          OFFERING    NET AMOUNT        DEALER
AMOUNT OF PURCHASE.........          PRICE        INVESTED         REALLOWANCE

Less than $100,000.........          4.50         4.71              4.00
$100,000 but less than $250,000      3.50         3.63              3.00
$250,000 but less than $500,000      2.50         2.56              2.00
$500,000 but less than $1,000,000    2.00         2.04              1.75
$1,000,000 or more.........          0.00         0.00              see below

The schedule of sales charges above is applicable to purchases of Class A shares
of the fund by (i) an individual, (ii) an individual and his or her spouse and
children under the age of 21 and (iii) a trustee or other fiduciary of a trust
estate or fiduciary account or related trusts or accounts including pension,
profit-sharing and other employee benefit trusts qualified under Sections 401 or
408 of the Code although more than one beneficiary is involved. The sales
charges applicable to a current purchase of Class A shares of the fund by a
person listed above is determined by adding the value of shares to be purchased
to the aggregate value (at the then current offering price) of shares of any of
the other Pioneer mutual funds previously purchased and then owned, provided PFD
is notified by such person or his or her broker-dealer each time a purchase is
made which would qualify. Pioneer mutual funds include all mutual funds for
which PFD serves as principal underwriter. At the sole discretion of PFD,
holdings of funds domiciled outside the U.S., but which are managed by
affiliates of Pioneer, may be included for this purpose. No sales charge is
payable at the time of purchase on investments of $1 million or more, or for
purchases by participants in certain group plans described below subject to a
CDSC of 1% which may be imposed in the event of a redemption of Class A shares
within 12 months of purchase. PFD may, in its discretion, pay a commission to
broker-dealers who initiate and are responsible for such purchases as follows:
1% on the first $5 million invested; 0.50% on the next $45 million invested; and
0.25% on the excess over $50 million invested. These commissions shall not be
payable if the purchaser is affiliated with the broker-dealer or if the purchase
represents the reinvestment of a redemption made during the previous 12 calendar
months. Broker-dealers who receive a commission in connection with Class A share
purchases at net asset value by 401(a) or 401(k) retirement plans with 1,000 or
more eligible participants or with at least $10 million in plan assets will be
required to return any commissions paid or a pro rata portion thereof if the
retirement plan redeems its shares within 12 months of purchase. Contingent upon
the achievement of certain sales objectives, PFD may pay to Mutual of Omaha
Investor Services, Inc. [50%] of PFD's retention of any sales commission on
sales of the fund's Class A shares through such dealer. From time to time, PFD
may elect to reallow the entire initial sales charge to participating dealers
for all Class A sales with respect to which orders are placed during a
particular period. Dealers to whom substantially the entire sales charge is
reallowed may be deemed to be underwriters under the federal securities laws.

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

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

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

CLASS B SHARES

You may buy Class B shares at the net asset value per share next computed after
receipt of a purchase order without the imposition of an initial sales charge;
however, Class B shares redeemed within six years of purchase will be subject to
a CDSC at the rates shown in the table below. The charge will be assessed on the
amount equal to the lesser of the current market value or the original purchase
cost of the shares being redeemed. No CDSC will be imposed on increases in
account value above the initial purchase price, including shares derived from
the reinvestment of dividends or capital gains distributions.

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

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

                  .........                          CDSC AS A % 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

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

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

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

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

12.      REDEEMING SHARES

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

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

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

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

Purchases of Class A shares of the fund at a time when you have a SWP in effect
may result in the payment of unnecessary sales charges and may, therefore, be
disadvantageous. SWP redemptions reduce and may ultimately exhaust the number of
shares in your account. In addition, the amounts received by a shareholder
cannot be considered as yield or income on his or her investment because part of
such payments may be a return of his or her investment.

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

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

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

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

13.       TELEPHONE TRANSACTIONS

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

To confirm that each transaction instruction received by telephone is genuine,
the fund will record each telephone transaction, require the caller to provide
the personal identification number ("PIN") for the account and send you a
written confirmation of each telephone transaction. Different procedures may
apply to accounts that are registered to non-U.S. citizens or that are held in
the name of an institution or in the name of an investment broker-dealer or
other third party. If reasonable procedures, such as those described above, are
not followed, the fund may be liable for any loss due to unauthorized or
fraudulent instructions. The fund may implement other procedures from time to
time. In all other cases, neither the fund, PSC nor PFD will be responsible for
the authenticity of instructions received by telephone; therefore, you bear the
risk of loss for unauthorized or fraudulent telephone transactions.

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

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

FactFoneSM allows shareholders to hear the following recorded fund information:



<PAGE>


     o     net asset value prices for all Pioneer mutual funds;

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

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

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


<PAGE>



Yields are calculated in accordance with SEC mandated standard formulas.

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

14.      PRICING OF SHARES

The net asset value per share of each class of the fund is determined as of the
close of regular trading on the Exchange (normally 4:00 p.m. Eastern time) on
each day on which the Exchange is open for trading. As of the date of this
statement of additional information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day. The net asset value per share of each
class of the fund is also determined on any other day on which the level of
trading in its portfolio securities is sufficiently high that the current net
asset value per share might be materially affected by changes in the value of
its portfolio securities. The fund is not required to determine its net asset
value per share on any day on which no purchase orders in good order for fund
shares are received and no shares are tendered and accepted for redemption.
Securities are valued at the last sale price on the principal exchange or market
where they are traded. Securities which have not traded on the date of valuation
or securities for which sales prices are not generally reported are valued at
the mean between the current bid and asked prices. Securities quoted in foreign
currencies are converted to U.S. dollars utilizing foreign exchange rates
employed by the fund's independent pricing services. Generally, trading in
foreign securities is substantially completed each day at various times prior to
the close of regular trading on the Exchange. The values of such securities used
in computing the net asset value of the fund's shares are determined as of such
times. Foreign currency exchange rates are also generally determined prior to
the close of regular trading on the Exchange. Occasionally, events which affect
the values of such securities and such exchange rates may occur between the
times at which they are determined and the close of regular trading on the
Exchange and will therefore not be reflected in the computation of the fund's
net asset value. If events materially affecting the value of such securities
occur during such period, then these securities may be valued at their fair
value as determined in good faith by the Trustees. All assets of the fund for
which there is no other readily available valuation method are valued at their
fair value as determined in good faith by the Trustees, although the actual
computations may be made by persons acting pursuant to the direction of the
Board of Trustees.

The net asset value per share of each class of the fund is computed by taking
the value of all of the fund's assets attributable to a class, less the fund's
liabilities attributable to that class, and dividing the result by the number of
outstanding shares of that class. For purposes of determining net asset value,
expenses of the classes of the fund are accrued daily and taken into account.
The fund's maximum offering price per Class A share is determined by adding the
maximum sales charge to the net asset value per Class A share. Class B, 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 intends to elect to be treated and to qualify each year as a "regulated
investment company" under Subchapter M of the Code so that it will not pay
federal income tax on income and capital gains distributed to shareholders as
required under the Code. If the fund did not qualify as a regulated investment
company, it would be treated as a U.S. corporation subject to federal income
tax. Under the Code, the fund will be subject to a nondeductible 4% federal
excise tax on a portion of its undistributed ordinary income and capital gains
if it fails to meet certain distribution requirements with respect to each
calendar year. The fund intends to make distributions in a timely manner and
accordingly does not expect to be subject to the excise tax.

The fund's policy is to pay to shareholders dividends from net long-term capital
gains, if any, in November. The fund pays income dividends and distributions
from net short-term capital gains, if any, in the last business day of the month
or shortly thereafter. Dividends from income and/or capital gains may also be
paid at such other times as may be necessary for the fund to avoid federal
income or excise tax.

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

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

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

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

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

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

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

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

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

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

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

The fund's dividends and distributions will not qualify for any dividends
received deduction that might otherwise be available for certain dividends
received by shareholders that are corporations.

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

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

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

16.      INVESTMENT RESULTS

QUOTATIONS, COMPARISONS AND GENERAL INFORMATION

From time to time, in advertisements, in sales literature or in reports to
shareholders, the past performance of the fund may be illustrated and/or
compared with that of other mutual funds with similar investment objectives and
to stock or other relevant indices. For example, the Fund may compare a class'
yield and/or total return to the Lehman Brothers Government/Corporate Bond
Index, U.S. Government bond rates, 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 indexes or indicators of
economic activity, e.g., inflation or interest rates. The fund may also include
securities industry or comparative performance information generally and in
advertising or materials marketing the fund's shares. Performance rankings and
listings reported in newspapers or national business and financial publications,
such as BARRON'S, BUSINESS WEEK, CONSUMERS DIGEST, CONSUMER REPORTS, FINANCIAL
WORLD, FORBES, FORTUNE, INVESTORS BUSINESS DAILY, KIPLINGER'S PERSONAL FINANCE
MAGAZINE, MONEY MAGAZINE, NEW YORK TIMES, SMART MONEY, USA TODAY, U.S. NEWS AND
WORLD REPORT, THE WALL STREET JOURNAL and WORTH may also be cited (if the fund
is listed in any such publication) or used for comparison, as well as
performance listings and rankings from various other sources including Bloomberg
Financial Markets, CDA/Wiesenberger, Donoghue's Mutual Fund Almanac, Ibbotson
Associates, Investment Company Data, Inc., Johnson's Charts, Kanon Bloch Carre
and Co., Lipper Analytical Services, Inc., Micropal, Inc., Morningstar, Inc.,
Schabacker Investment Management and Towers Data Systems, Inc.

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

The fund may also present, from time to time, historical information depicting
the value of a hypothetical account in one of 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:

                  .........     a-b     6
                  YIELD = 2[ ( ----- +1) -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.

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

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:
                        n
                  P(1+T) = ERV

Where:

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

         T        =        average annual total return

         n        =        number of years

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

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

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

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

19.       APPENDIX B - DESCRIPTION OF SHORT-TERM DEBT, CORPORATE BOND
          AND PREFERRED STOCK RATINGS1

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

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

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

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

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

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

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

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

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

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

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

MOODY'S DEBT RATINGS

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

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

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

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

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

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

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

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

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

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

MOODY'S PREFERRED STOCK RATINGS

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

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

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

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

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

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

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

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

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

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

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

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

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

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

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

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

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

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

STANDARD & POOR'S LONG-TERM CREDIT RATINGS

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

STANDARD & POOR'S PREFERRED STOCK RATINGS

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

Preferred stock ratings are based on the following considerations:

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

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

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

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

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

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

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

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

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

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

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

COMPARATIVE PERFORMANCE INDEX DESCRIPTIONS

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

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

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

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

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

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

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

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

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

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

MORGAN STANLEY CAPITAL INTERNATIONAL ("MSCI"). These indices are in US dollar
terms with gross dividends reinvested. 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's international indices are based on the share
prices of approximately 1,700 companies listed on stock exchanges in the 22
countries that make up the MSCI World Index. MSCI's emerging market indices are
comprised of approximately 1000 stocks from 26 countries.

Countries in the MSCI EAFE Index are: Australia, Austria, Belgium, Denmark,
Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Malaysia,
Netherlands, New Zealand, Norway, Singapore, Spain, Sweden, Switzerland and
United Kingdom.

Countries in the MSCI Emerging Markets Free Index are: Argentina, Brazil, Chile,
China Free, Czech Republic, Colombia, Greece, Hungary, India, Indonesia Free,
Israel, Jordan, Korea (at 50%), Malaysia Free, Mexico Free, Pakistan, Peru,
Philippines Free, Poland, Portugal, South Africa, Sri Lanka, Taiwan (at 50%),
Thailand Free, Turkey and Venezuela.

MSCI All Country (AC) Asia Free ex Japan: This index is made up of the following
12 countries: China Free, Hong Kong, India, Indonesia Free, Korea @50%, Malaysia
Free, Pakistan, Philippines Free, Singapore Free, Sri Lanka, Taiwan @50% and
Thailand Free.

MSCI All Country (AC) Asia Pacific Free ex Japan: This index is made up of the
following 14 countries: Australia, China Free, Hong Kong, India, Indonesia Free,
Korea @50%, Malaysia Free, New Zealand, Pakistan, Philippines Free, Singapore
Free, Sri Lanka, Taiwan @50% and Thailand Free.

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

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

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

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

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

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

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

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

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

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

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

LEHMAN 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.

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

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

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

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

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

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

         7. The Manager is an independent contractor and not an employee of the
Funds for any purpose. If any occasion should arise in which the Manager gives
any advice to its clients concerning the shares of the Funds, the Manager will
act solely as investment counsel for such clients and not in any way on behalf
of the Funds or any series thereof.

         8. This Agreement states the entire agreement of the parties hereto
with respect to the subject matter of this Agreement and its intended to be the
complete and exclusive statement of the terms hereof. It may not be added to or
changed orally, and may not be modified or rescinded except by a writing signed
by the parties hereto and in accordance with the 1940 Act, when applicable.

and construed in accordance with the laws of the Commonwealth of Massachusetts.

         10. Any term or provision of this Agreement which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction be ineffective
to the extent of such invalidity or unenforceability without rendering invalid
or unenforceable the remaining terms or provisions of this Agreement or
affecting the validity or enforceability of any of the terms or provisions of
this Agreement in any other jurisdiction.

         11. This Agreement may be executed simultaneously in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by this duly authorized officers and their seal to be hereto affixed as
of the day and year first above written.
