Prospectus
August 30, 1996
    

Pioneer Bond Fund (the "Fund") seeks current income from a high quality
portfolio with due regard to preservation of capital and prudent investment
risk. Consistent therewith, the Fund also seeks to maintain dividend payments
at a relatively stable level. At least 85% of the Fund's total assets must be
invested in debt securities issued or guaranteed by the United States
("U.S.") Government or its agencies or instrumentalities, debt securities
(including convertible securities) rated within the three highest grades by
the major recognized bond services and comparably rated commercial paper and
cash and cash equivalents. The Fund may invest the balance (up to 15%) of its
total assets in debt securities that are rated in the fourth highest grade by
the major recognized bond services and in commercial paper that is of
comparable quality.

FUND RETURNS AND SHARE PRICES FLUCTUATE AND THE VALUE OF YOUR ACCOUNT, UPON
REDEMPTION, MAY BE MORE OR LESS THAN THE VALUE OF YOUR ORIGINAL INVESTMENT.
SHARES IN THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK OR DEPOSITORY INSTITUTION, AND THE SHARES ARE NOT
FEDERALLY INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL
RESERVE BOARD OR ANY OTHER GOVERNMENT AGENCY.

   
This Prospectus provides the information about the Fund that you should know
before investing in the Fund. Please read and retain it for your future

I. EXPENSE INFORMATION

   
This table is designed to help you understand the charges and expenses that
you, as a shareholder, will bear directly or indirectly when you invest in
the Fund. The table reflects annual operating expenses based upon actual
expenses of the Class A and Class B shares for the fiscal year ended June 30,
1996. For Class C shares, operating expenses are based on estimated expenses
that would have been incurred if Class C shares had been outstanding for the
entire fiscal year ended June 30, 1996.

  + Class C shares were first offered on January 31, 1996.

(1) Purchases of $1 million or more and certain purchases by participants in
    a group plan are not subject to an initial sales charge but may be
    subject to a contingent deferred sales charge ("CDSC") as further
    described under "How to Sell Fund Shares."
    

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

 Example:

   
You would pay the following expenses on a $1,000 investment, assuming a 5%
annual return, with or without redemption at the end of each time period:
    

                        1 Year      3 Years     5 Years     10 Years
                        --------    --------    --------   ----------
Class A Shares            $56         $81        $107         $182
Class B Shares
 - Assuming
   complete
   redemption at
   end of period          $60         $91        $125         $207*
 - Assuming no
   redemption             $20         $61        $105         $207*
Class C shares**
 - Assuming
   complete
   redemption at
   end of period          $31         $67        $115         $247
 - Assuming no
   redemption             $22         $67        $115         $247

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

** Class C shares redeemed during the first year after purchase are subject
   to a 1% CDSC.
    

The example above assumes the reinvestment of all dividends and distributions
and that the percentage amounts listed under "Annual Operating Expenses"
remain the same each year.

The example is designed for informational purposes only, and should not be
considered a representation of past or future expenses or return. Actual Fund
expenses and return vary from year to year and may be higher or lower than
those shown.

   
For further information regarding management fees, 12b-1 fees and other
expenses of the Fund, see "Management of the Fund," "Distribution Plans" and
"How to Buy Fund Shares" in this Prospectus and "Management of the Fund" and
"Underwriting Agreement and Distribution Plans" in the Statement of
Additional Information. The Fund's payment of a 12b-1 fee may result in
long-term shareholders indirectly paying more than the economic equivalent of
the maximum sales charge permitted under the Conduct Rules of the National
Association of Securities Dealers, Inc. ("NASD").

The maximum initial sales charge is reduced on purchases of specified amounts
of Class A shares and the value of Class A shares owned in other Pioneer
mutual funds is taken into account in determining the applicable initial
sales charge. See "How to Buy Fund Shares." No sales charge is applied to
exchanges of shares of other publicly available Pioneer mutual funds. See

III. INVESTMENT OBJECTIVES AND POLICIES
    

The Fund's primary objective is to provide current income from a high quality
portfolio with due regard to preservation of capital and prudent investment
risk. The Fund has a secondary objective of maintaining a relatively stable
level of dividends; however, the level of dividends will be maintained only
if consistent with preserving the high quality of the Fund's portfolio.

At least 85% 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) investment-grade securities, that is, debt securities,
including convertible securities, that are rated "A" or higher by the major
recognized bond services (for a description of ratings see the Appendix to
the Statement of Additional Information), and comparably rated commercial
paper and (c) cash and cash equivalents (such as certificates of deposit,
repurchase agreements maturing in one week or less and bankers' acceptances).

The Fund may also invest up to 15% of its total assets in debt securities,
including convertible securities, which are rated in the fourth highest grade
by the major recognized bond services and commercial paper which is
comparable. Securities in the fourth highest grade (i.e., rated Baa by
Moody's Investor Services, Inc. or BBB by Standard & Poor's Ratings Group)
are considered medium grade, neither highly protected nor poorly secured,
with some elements of uncertainty over any great length of time and certain
speculative characteristics as well.

None of the Fund's portfolio may be invested in debt securities which are
rated below the fourth highest grade or are unrated, except that the Fund may
hold debt securities the ratings of which are reduced subsequent to purchase.
The Fund may not invest in preferred or common stocks.

The Fund may invest in the following mortgage-backed securities.
Collateralized mortgage obligations ("CMOs") are obligations fully
collateralized by a portfolio of mortgages or mortgage-related securities.
Payments of principal and interest on the mortgages are passed to a special
purpose entity, then through to the holders of the CMOs on the same schedule
as they are received, although certain classes of CMOs have priority over
others with respect to the receipt of prepayments on the mortgages.
Therefore, depending on the type of CMOs in which the Fund invests, the
investment may be subject to a greater or lesser risk of prepayment than
other types of mortgage-related securities. A real estate mortgage investment
conduit ("REMIC") is a form of CMO that qualifies for special tax treatment
under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund
may acquire "regular" interests in REMICs but does not intend, under current
tax law, to acquire residual interests in REMICs. Mortgage-backed securities
are derivative securities and provide for payments based on or derived from
the performance of the underlying mortgage

                                      4
<PAGE>

assets. Risks associated with mortgage-backed securities include the failure
of a counter-party to meet its commitments, adverse interest rate changes and
the effects of prepayments on mortgage cash flows. When interest rates
decline, the value of an investment in debt obligations can be expected to
rise. Conversely, when interest rates rise the value of an investment in debt
obligations can be expected to decline. Like other debt obligations, when
interest rates rise the value of a mortgage-backed security generally will
decline; however, when interest rates are declining, the value of
mortgage-backed securities with prepayment features may not increase as much
as that of other debt obligations. Mortgage-backed securities may be less
effective than traditional debt obligations of similar maturity at
maintaining yields during periods of declining interest rates.

Not more than 15% of the Fund's assets may be invested in foreign securities
and not more than 5% of its total assets may be invested in foreign
securities that are not listed on a recognized foreign or domestic exchange,
provided that purchases of Canadian securities are not subject to the
limitations in this paragraph. Investments in foreign securities may be
subject to risks including, but not limited to, foreign taxes and
restrictions, illiquidity and fluctuations in currency values. In addition,
the financial information available on issuers of foreign debt securities is
frequently not as accurate or complete as would be available for a comparable
domestic issuer. See "Other Policies and Risks" in the Statement of
Additional Information.

The Fund's portfolio will be fully managed by purchasing and selling
securities, as well as holding selected securities to maturity. The Fund's
investment manager employs "cycle analysis" in the management of the Fund's
portfolio. Cycle analysis is the process of managing the Fund's portfolio by
analyzing the business and credit cycles of the economy to identify and
monitor trends in interest rates and to identify fixed-income securities with
characteristics most likely to meet the Fund's objectives at given stages in
the cycles. Relying on analysis of economic indicators, as well as price,
yield and maturity data of individual securities, this process requires
ongoing adjustments to the portfolio based on the relative values or
maturities of individual debt securities or changes in the creditworthiness
or overall investment merit of an issue.

Any such change in the portfolio may result in increases or decreases in the
Fund's current income available for distribution to shareholders and in its
holding of debt securities which sell at moderate to substantial premiums or
discounts from face value. If the Fund's expectations of changes in interest
rates or its evaluation of the normal yield relationships between two
securities prove to be incorrect, the Fund's income, net asset value and
potential capital gain may be reduced or its potential capital loss may be
increased. An increase in interest rates will generally reduce the value of
portfolio investments (and, therefore, the net asset value of the shares of
the Fund), and a decline in interest rates will generally increase their
value.

   
It is the policy of the Fund not to engage in trading for short-term profits.
The Fund will engage in portfolio trading if it believes a transaction net of
costs (including custodian's fees) will contribute to the achievement of its
investment objective. See "Financial Highlights" for actual portfolio
turnover rates.
    

The foregoing objectives and investment policies (other than the discussion
of "cycle analysis") may not be changed without shareholder approval.
Government securities include U.S. Treasury obligations such as bills, bonds
and notes which principally differ in their interest rates, maturities and
times of issuance, and obligations issued or guaranteed by U.S. Government
agencies or instrumentalities supported by the full faith and credit of the
U.S. Treasury (securities of the Government National Mortgage Association,
"GNMA"), the authority of the U.S. Government to purchase certain obligations
of the issuer (securities of the Federal National Mortgage Association,
"FNMA"), the limited authority of the issuer to borrow from the U.S. Treasury
(securities of the Student Loan Marketing Association) or only the credit of
the issuer. No assurance can be given that the U.S. Government will provide
financial support to U.S. Government agencies or instrumentalities in the
future, other than as set forth above, since it is not legally obligated to
do so. Interest payments of U.S. Treasury obligations are generally fixed.
Other investment policies and restrictions on investment are described in the
Statement of Additional Information, including a policy on lending portfolio
securities. Since all investments are subject to inherent market risks and
fluctuations in value due to earnings, economic conditions and other factors,
the Fund, of course, cannot assure that its investment objectives will be
achieved.

IV. MANAGEMENT OF THE FUND

The Fund's Board of Trustees has overall responsibility for management and
supervision of the Fund. There are currently eight Trustees, six of whom are
not "interested persons" of the Fund as defined in the Investment Company Act
of 1940, as amended (the "1940 Act"). The Board meets at least quarterly. By
virtue of the functions performed by PMC as investment adviser, the Fund
requires no employees other than its executive officers, all of whom receive
their compensation from PMC or other sources. The Statement of Additional
Information contains the names and general background of each Trustee and
executive officer of the Fund.

   
Each domestic fixed income portfolio managed by PMC, including the Fund, is
overseen by the Domestic Fixed Income Portfolio Management Committee, which
consists of PMC's most senior domestic fixed income professionals, and a
Portfolio Management Committee, which consists of PMC's fixed income
portfolio managers. Both committees are chaired by Mr. David Tripple, PMC's
President and Chief Investment Officer and Executive Vice President of each
of the Pioneer mutual funds. Mr. Tripple joined PMC in 1974 and has had
general responsibility for PMC's investment operations and specific portfolio
assignments for over five years. Fixed income investments at PMC, including
those made on behalf of the Fund, are under the general supervision of Mr.
Sherman Russ, a Senior Vice President of PMC. Mr. Russ joined PMC in 1983 and
has been responsible for the day-to-day management of the Fund since March
1988.
    

                                      5

Investment advisory services are provided to the Fund by PMC pursuant to a
management contract between PMC and the Fund. PMC is responsible for the
overall management of the Fund's business affairs, subject only to the
authority of the Board of Trustees. PMC is a wholly-owned subsidiary of The
Pioneer Group, Inc. ("PGI"), a Delaware corporation. Pioneer Funds
Distributor, Inc. ("PFD"), an indirect wholly-owned subsidiary of PGI, is
the principal underwriter of shares of the Fund.

In addition to the Fund, PMC also manages and serves as the investment
adviser for other mutual funds and is an investment adviser to certain other
institutional accounts. PMC's and PFD's executive offices are located at 60
State Street, Boston, Massachusetts 02109. In an effort to avoid conflicts of
interest with the Fund, the Fund and PMC 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.

Under the terms of its contract with the Fund, PMC assists in the management
of the Fund and is authorized in its discretion to buy and sell securities
for the account of the Fund. PMC pays all the ordinary operating expenses,
including executive salaries and the rental of certain office space, related
to its services for the Fund with the exception of the following which are to
be paid by the Fund: (a) charges and expenses for fund accounting, pricing
and appraisal services and related overhead, including, to the extent such
services are performed by personnel of PMC 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, individual states or blue sky securities agencies,
territories and foreign countries, including the preparation of Prospectuses
and Statements of Additional Information for filing with regulatory agencies;
(g) all expenses of shareholders' and Trustees' meetings and of preparing,
printing and distributing prospectuses, notices, proxy statements and all
reports to shareholders and to governmental agencies; (h) charges and
expenses of legal counsel to the Fund and the Trustees; (i) distribution fees
paid by the Fund in accordance with Rule 12b-1 promulgated by the SEC
pursuant to the 1940 Act; (j) compensation of those Trustees of the Fund who
are not affiliated with or interested persons of PMC, 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 all brokers' and underwriting
commissions chargeable to the Fund in connection with securities transactions
to which the Fund is a party.

Orders for the Fund's portfolio securities transactions are placed by PMC,
which strives to obtain the best price and execution for each transaction. In
circumstances in which two or more broker-dealers are in a position to offer
comparable prices and execution, consideration may be given to whether the
broker-dealer provides investment research or brokerage services or sells
shares of any Pioneer mutual fund. See the Statement of Additional
Information for a further description of PMC's brokerage allocation
practices.

As compensation for its management services and certain expenses which PMC
incurs, PMC is entitled to a management fee equal to 0.50% per annum of the
Fund's average daily net assets. The fee is normally computed daily and paid
monthly. During the fiscal year ended June 30, 1996, the Fund incurred
expenses of approximately $1,484,000, including management fees paid or
payable to PMC of $588,000.

John F. Cogan, Jr., Chairman and President of the Fund, Chairman of PFD,
President and a Director of PGI and Chairman and a Director of PMC, owned
approximately 14% of the outstanding capital stock of PGI as of the date of
this Prospectus.
    

V. FUND SHARE ALTERNATIVES

   
The Fund continuously offers three Classes of shares designated as Class A,
Class B and Class C shares, as described more fully in "How to Buy Fund
Shares." If you do not specify in your instructions to the Fund which Class
of shares you wish to purchase, exchange or redeem, the Fund will assume that
your instructions apply to Class A shares.

Class A Shares.   If you invest less than $1 million in Class A shares, you
will pay an initial sales charge. Certain purchases may qualify for reduced
initial sales charges. If you invest $1 million or more in Class A shares, no
sales charge will be imposed at the time of purchase, however, shares
redeemed within 12 months of purchase may be subject to a CDSC. Class A
shares are subject to distribution and service fees at a combined annual rate
of up to 0.25% of the Fund's average daily net assets attributable to Class A
shares.
    

Class B Shares.   If you plan to invest up to $250,000, Class B shares are
available to you. Class B shares are sold without an initial sales charge,
but are subject to a CDSC of up to 4% if redeemed within six years. Class B
shares are subject to distribution and service fees at a combined annual rate
of 1.00% of the Fund's average daily net assets attributable to Class B
shares. Your entire investment in Class B shares is available to work for you
from the time you make your investment, but the higher distribution fee paid
by Class B shares will cause your Class B shares (until conversion) to have a
higher expense ratio and to pay lower dividends, to the extent dividends are
paid, than Class A shares. Class B shares will automatically convert to Class
A shares, based on relative net asset value, approximately eight years after
the initial purchase.

   
Class C Shares.   Class C shares are sold without an initial sales charge,
but are subject to a 1% CDSC if they are
    

                                      6
<PAGE>

   
redeemed within the first year after purchase. Class C shares are subject to
distribution and service fees at a combined annual rate of up to 1.00% of the
Fund's average daily net assets attributable to Class C shares. Your entire
investment in Class C shares is available to work for you from the time you
make your investment, but the higher distribution fee paid by Class C shares
will cause your Class C shares to have a higher expense ratio and to pay
lower dividends, to the extent dividends are paid, than Class A shares. Class C
shares have no conversion feature.

Selecting a Class of Shares.   The decision as to which Class to purchase
depends on the amount you invest, the intended length of the investment and
your personal situation. If you are making an investment that qualifies for
reduced sales charges, you might consider Class A shares. If you prefer not
to pay an initial sales charge on an investment of $250,000 or less and you
plan to hold the investment for at least six years, you might consider Class
B shares. If you prefer not to pay an initial sales charge and you plan to
hold your investment for one to eight years, you may prefer Class C shares.

Investment dealers and their representatives may receive different
compensation depending on which Class of shares they sell. Shares may be
exchanged only for shares of the same Class of another Pioneer mutual fund
and shares acquired in the exchange will continue to be subject to any CDSC
applicable to the shares of the Fund originally purchased. Shares sold
outside the U.S. to persons who are not U.S. citizens may be subject to
different sales charges, CDSCs and dealer compensation arrangements in
accordance with local laws and business practices.
    

VI. SHARE PRICE

   
Shares of the Fund are sold at the public offering price, which is the net
asset value per share, plus the applicable sales charge. Net asset value per
share of a Class of the Fund is determined by dividing the value of its
assets, less liabilities attributable to that Class, by the number of shares
of that Class outstanding. The net asset value is computed once daily, on
each day the New York Stock Exchange (the "Exchange") is open, as of the
close of regular trading on the Exchange.

Securities are valued at the last sale price on the principal exchange or
market where they are traded. Securities which have not traded on the date of
valuation or securities for which sales prices are not generally reported are
valued at the mean between the current bid and asked prices. 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 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 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 the Exchange
and will therefore not be reflected in the computation of the Fund's net
asset value. If events materially affecting the value of such securities
occur during such period, then these securities are valued at their fair
value as determined in good faith by the Trustees. All assets of the Fund for
which there is no other readily available valuation method are valued at fair
value as determined in good faith by the Trustees.
    

VII. HOW TO BUY FUND SHARES

   
You may buy Fund shares from any securities broker-dealer which has a sales
agreement with PFD. If you do not have a securities broker-dealer, please
call 1-800-225-6292. Shares will be purchased at the public offering price,
that is, the net asset value per share, plus any applicable sales charge,
next computed after receipt of a purchase order, except as set forth below.

The minimum initial investment is $1,000 for Class A, Class B and Class C
shares except as specified below. The minimum initial investment is $50 for
Class A accounts being established to utilize monthly bank drafts, government
allotments, payroll deduction and other similar automatic investment plans.
Separate minimum investment requirements apply to retirement plans and to
telephone and wire orders placed by broker-dealers; no sales charges or
minimum requirements apply to the reinvestment of dividends or capital gains
distributions. The minimum subsequent investment is $50 for Class A shares
and $500 for Class B and Class C shares except that the subsequent minimum
investment amount for Class B and Class C share accounts may be as little as
$50 if an automatic investment plan is established (see "Automatic Investment
Plans").

Telephone Purchases.   Your account is automatically authorized to have the
telephone purchase privilege unless you indicate otherwise on your Account
Application or by writing to Pioneering Services Corporation ("PSC"). The
telephone purchase option may be used to purchase additional shares for an
existing fund account; it may not be used to establish a new account. Proper
account identification will be required for each telephone purchase. A
maximum of $25,000 per account may be purchased by telephone each day. The
telephone purchase privilege is available to Individual Retirement Accounts
("IRAs") but may not be available to other types of retirement plan accounts.
Call PSC for more information.

You are strongly urged to consult with your financial representative prior to
requesting a telephone purchase. To purchase shares by telephone, you must
establish your bank account of record by completing the appropriate section
of your Account Application or an Account Options Form. PSC will
electronically debit the amount of each purchase from this predesignated bank
account. Telephone purchases may not be made for 30 days after the
establishment of your bank of record or any change to your bank information.

Telephone purchases will be priced at the net asset value plus any applicable
sales charge next determined after PSC's receipt of a telephone purchase
instruction and receipt of
    


                                      7
<PAGE>

good funds (usually three days after the purchase instruction). You may
always elect to deliver purchases to PSC by mail. See "Telephone Transactions
and Related Liabilities" for additional information.

Class A Shares

   
You may buy Class A shares at the public offering price as follows:
    

                         Sales Charge as a % of
                          ----------------------

$1,000,000 or more         -0-          -0-         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 Section 401 or 408 of the Internal Revenue Code in 1986, as
amended (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. See
the "Letter of Intention" section of the Account Application.

No sales charge is payable at the time of purchase on investments of $1
million or more or for purchases by certain Group Plans (described below)
subject to a CDSC of 1% which may be imposed in the event of a redemption of
Class A shares within 12 months of purchase. See "How to Sell Fund Shares."
PFD may, in its discretion, pay a commission to broker-dealers who initiate
and are responsible for such purchases as follows: 1% on the first $5 million
invested; 0.50% on the next $45 million; and 0.25% on the excess over $50
million. Broker-dealers who receive a commission in connection with Class A
share purchases at net asset value by 401(a) or 401(k) retirement plans with
1,000 or more eligible participants or with at least $10 million in plan
assets will be required to return any commission paid or a pro rata portion
thereof if the retirement plan redeems its shares within 12 months of
purchase. See also "How to Sell Fund Shares ." These commissions will not be
paid if the purchaser is affiliated with the broker-dealer or if the purchase
represents the reinvestment of a redemption made during the previous 12
calendar months. In connection with PGI's acquisition of Mutual of Omaha Fund
Management Company and 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.

Qualifying for a Reduced Sales Charge.   Class A shares of the Fund may be
sold at a reduced or eliminated sales charge to certain group plans ("Group
Plans") under which a sponsoring organization makes recommendations to,
permits group solicitation of, or otherwise facilitates purchases by, its
employees, members or participants. Class A shares of the Fund may be sold at
net asset value without a sales charge to 401(k) retirement plans with 100 or
more participants or at least $500,000 in plan assets. Information about such
arrangements is available from PFD.

Class A shares of the Fund may also be sold at net asset value per share
without a sales charge to: (a) current or former Trustees and officers of the
Fund and partners or employees of its legal counsel; (b) current or former
directors, officers, employees or sales representatives of PGI or its
subsidiaries; (c) current or former directors, officers, employees or sales
representatives of any subadviser or predecessor investment adviser to any
investment company for which PMC serves as investment adviser, and the
subsidiaries or affiliates of such persons; (d) current or former officers,
partners, employees or registered representatives of broker-dealers which
have entered into sales agreements with PFD; (e) members of the immediate
families of any of the foregoing persons; (f) any trust, custodian, pension,
profit-sharing or other benefit plan of the foregoing persons; (g) insurance
company separate accounts; (h) certain "wrap accounts" for the benefit of
clients of financial planners adhering to standards established by PFD; (i)
other funds and accounts for which PMC or any of its affiliates serves as
investment adviser or manager; and (j) certain unit investment trusts. Shares
so purchased are purchased for investment purposes and may not be resold
except through redemption or repurchase by or on behalf of the Fund. The
availability of this privilege is conditioned on the receipt by PFD of
written notification of eligibility. Class A shares of a Fund may be sold at
net asset value per share without a sales charge to Optional Retirement
Program (the "Program") participants if (i) the employer has authorized a
limited number of investment company providers for the Program, (ii) all
authorized investment company providers offer their shares to Program
participants at net asset value, (iii) the employer has agreed in writing to
actively promote the authorized investment providers to Program participants
and (iv) the Program provides for a matching contribution for each
participant contribution. Shares of the Fund may also be issued at net asset
value without a sales charge in connection with certain reorganization,
liquidation or acquisition transactions involving other investment companies
or personal holding companies.
    

Reduced sales charges for Class A shares are available through an agreement
to purchase a specified quantity of Fund shares over a designated 13-month
period by completing the "Letter of Intention" section of the Account
Applica-

                                      8
<PAGE>

   
tion. Information about the Letter of Intention procedure, including its
terms, is contained in the Statement of Additional Information.

Investors who are clients of a broker-dealer with a current sales agreement
with PFD may purchase shares of the Fund at net asset value, without a sales
charge, to the extent that the purchase price is paid out of proceeds from
one or more redemptions by the investor of shares of certain other mutual
funds. In order for a purchase to qualify for this privilege, the investor
must document to the broker-dealer that the redemption occurred within 60
days immediately preceding the purchase of Class A shares of the Fund; that
the client paid a sales charge on the original purchase of the shares
redeemed; and that the mutual fund whose shares were redeemed also offers net
asset value purchases to redeeming shareholders of any of the Pioneer mutual
funds. Further details may be obtained from PFD.
    

Class B Shares

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

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

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

        Year Since            CDSC as a Percentage of Dollar
         Purchase                 Amount Subject to CDSC
- -------------------------    --------------------------------
First                                      4.0%
Second                                     4.0%
Third                                      3.0%
Fourth                                     3.0%
Fifth                                      2.0%
Sixth                                      1.0%
Seventh and thereafter                     none

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

   
Class B shares will automatically convert into Class A shares at the end of
the calendar quarter that is eight years after the purchase date, except as
noted below. Class B shares acquired by exchange from Class B shares of
another Pioneer fund will convert into Class A shares based on the date of
the initial purchase and the applicable CDSC. Class B shares acquired through
reinvestment of distributions will convert into Class A shares based on the
date of the initial purchase to which such shares relate. For this purpose,
Class B shares acquired through reinvestment of distributions will be
attributed to particular purchases of Class B shares in accordance with such
procedures as the Trustees may determine from time to time. The conversion of
Class B shares to Class A shares is subject to the continuing availability of
a ruling from the Internal Revenue Service ("IRS"), which the Fund has
obtained, or an opinion of counsel that such conversions will not constitute
taxable events for federal tax purposes. There can be no assurance that such
ruling will continue to be in effect at the time any particular conversion
would normally occur. The conversion of Class B shares to Class A shares will
not occur if such ruling is no longer in effect and such an 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 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 quarter will be aggregated and deemed to have been made on the first day of
that quarter. In processing redemptions of Class C shares, the Fund will
first redeem shares not subject to any CDSC, and then shares held for the
shortest period of time during the one-year period. As a result, you will pay
the lowest possible CDSC.

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

All Classes of Shares

Waiver or Reduction of Contingent Deferred Sales Charge.   The CDSC on Class B
shares may be waived or reduced for non-retirement accounts if: (a) the
redemption results from the death of all registered owners of an account (in
the case of UGMAs, UTMAs and trust accounts, waiver applies upon the death of
all beneficial owners) or a total and permanent disability (as defined in
Section 72 of the Code) of all registered owners occurring after the purchase
of the shares being redeemed or (b) the redemption is made in connection with
limited automatic redemptions as set forth in "Systematic Withdrawal Plans"
(limited in any year to 10% of
    


                                      9
<PAGE>

the value of the account in the Fund at the time the withdrawal plan is
established).

   
The CDSC on Class B shares may be waived or reduced for retirement plan
accounts if: (a) the redemption results from the death or a total and
permanent disability (as defined in Section 72 of the Code) occurring after
the purchase of the shares being redeemed of a shareholder or participant in
an employer-sponsored retirement plan; (b) the distribution is to a
participant in an IRA, 403(b) or employer-sponsored retirement plan, is part
of a series of substantially equal payments made over the life expectancy of
the participant or the joint life expectancy of the participant and his or
her beneficiary or as scheduled periodic payments to a participant (limited
in any year to 10% of the value of the participant's account at the time the
distribution amount is established; a required minimum distribution due to
the participant's attainment of age 70-1/2 may exceed the 10% limit only if
the distribution amount is based on plan assets held by Pioneer) or a
qualifying hardship distribution as defined by the Code or results from a
termination of employment (limited with respect to a termination to 10% per
year of the value of the plan's assets in the Fund as of the later of the
prior December 31 or the date the account was established unless the plan's
assets are being rolled over to or reinvested in the same class of shares of
a Pioneer mutual fund subject to the CDSC of the shares originally held); (c)
the distribution is from a 401(a) or 401(k) retirement plan and is a return
of excess employee deferrals or employee contributions; (d) the distribution
is from an IRA, 403(b) or employer-sponsored retirement plan and is to be
rolled over to or reinvested in the same class of shares in a Pioneer mutual
fund and which will be subject to the applicable CDSC upon redemption; (e)
the distribution is in the form of a loan to a participant in a plan which
permits loans (each repayment of the loan will constitute a new sale which
will be subject to the applicable CDSC upon redemption); or (f) the
distribution is from a qualified defined contribution plan and represents a
participant's directed transfer (provided that this privilege has been
pre-authorized through a prior agreement with PFD regarding participant
directed transfers).

The CDSC on Class C shares and on any Class A shares subject to a CDSC may be
waived or reduced as follows: (a) for automatic redemptions as described in
"Systematic Withdrawal Plans" (limited to 10% of the value of the account);
(b) if the redemption results from the death or a total and permanent
disability (as defined in Section 72 of the Code) occurring after the
purchase of the shares being redeemed of a shareholder or participant in an
employer-sponsored retirement plan; (c) if the distribution is part of a
series of substantially equal payments made over the life expectancy of the
participant or the joint life expectancy of the participant and his or her
beneficiary; or (d) if the distribution is to a participant in an
employer-sponsored retirement plan and is (i) a return of excess employee
deferrals or contributions, (ii) a qualifying hardship distribution as
defined by the Code, (iii) from a termination of employment, (iv) in the form
of a loan to a participant in a plan which permits loans, or (v) from a
qualified defined contribution plan and represents a participant's directed
transfer (provided that this privilege has been pre-authorized through a
prior agreement with PFD regarding participant directed transfers).

The CDSC on Class B and Class C shares and on any Class A shares subject to a
CDSC may be waived or reduced for either non-retirement or retirement plan
accounts if: (a) the redemption is made by any state, county, or city, or any
instrumentality, department, authority, or agency thereof, which is
prohibited by applicable laws from paying a CDSC in connection with the
acquisition of shares of any registered investment management company; or (b)
the redemption is made pursuant to the Fund's right to liquidate or
involuntarily redeem shares in a shareholder's account.

Broker-Dealers.   An order for any Class of Fund shares received by PFD from
a broker-dealer prior to the close of regular trading on the Exchange is
confirmed at the price appropriate for that Class as determined at the close
of regular trading on the Exchange on the day the order is received, provided
the order is received prior to PFD's close of business (usually, 5:30 p.m.
Eastern Time). It is the responsibility of broker-dealers to transmit orders
so that they will be received by PFD prior to its close of business. PFD or
its affiliates may provide additional compensation to certain dealers or such
dealers' affiliates based on certain objective criteria established from time
to time by PFD. All such payments are made out of PFD's or the affiliate's
own assets. These payments will not change the price an investor will pay for
shares or the amount that the Fund will receive from such sale.
    

General.   The Fund reserves the right in its sole discretion to withdraw all
or any part of the offering of shares when, in the judgment of the Fund's
management, such withdrawal is in the best interest of the Fund. An order to
purchase shares is not binding on, and may be rejected by, PFD until it has
been confirmed in writing by PFD and payment has been received.

VIII. HOW TO SELL FUND SHARES

You can arrange to sell (redeem) Fund shares on any day the Exchange is open
by selling either some or all of your shares to the Fund.

You may sell your shares either through your broker-dealer or directly to the
Fund. Please note the following:

(bullet) If you are selling shares from a retirement account, you must make
         your request in writing (except for exchanges to other Pioneer
         mutual funds which can be requested by phone or in writing). Call
         1-800-622-0176 for more information.

(bullet) If you are selling shares from a non-retirement account, you may use
         any of the methods described below.

   
Your shares will be sold at the share price next calculated after your order
is received in good order less any applicable CDSC. Sale proceeds generally
will be sent to you in cash, normally within seven days after your order is
received in good order. The Fund reserves the right to withhold payment of
the sale proceeds until checks received by the Fund in payment for the shares
being sold have cleared, which may take up to 15 calendar days from the
purchase date.
    

In Writing.   You may always sell your shares by delivering a written
request, signed by all registered owners, in good order to

                                      10
<PAGE>

PSC, however, you must use a written request, including a signature
guarantee, to sell your shares if any of the following situations applies:

(bullet) you wish to sell over $50,000 worth of shares,

(bullet) your account registration or address has changed within the last 30
         days,

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

(bullet) the check is not being made out to the account owners, or

(bullet) the sale proceeds are being transferred to a Pioneer mutual fund
         account with a different registration.

   
Your request should include your name, the Fund's name, your fund account
number, the Class of shares to be redeemed, the dollar amount or number of
shares to be redeemed, and meet any other applicable requirements as
described below. Unless instructed otherwise, PSC will send the proceeds of
the sale to the address of record. Fiduciaries and corporations are required
to submit additional documents. For more information, contact PSC at
1-800-225-6292.

Written requests will not be processed until they are received in good order
by PSC. Good order means that there are no outstanding claims or requests to
hold redemptions on the account, any certificates are endorsed by the record
owner(s) exactly as the shares are registered and the signature(s) are
guaranteed by an eligible guarantor. You should be able to obtain a signature
guarantee from a bank, broker, dealer, credit union (if authorized under
state law), securities exchange or association, clearing agency or savings
association. A notary public cannot provide a signature guarantee. Signature
guarantees are not accepted by facsimile ("fax"). For additional information
about the necessary documentation for redemption by mail, please contact PSC
at 1-800-225-6292.

By Telephone or by Fax.   Your account is automatically authorized to have
the telephone redemption privilege unless you indicate otherwise on your
Account Application or by writing to PSC. Proper account identification will
be required for each telephone redemption. A maximum of $50,000 per account
per day may be redeemed by telephone or fax and the proceeds may be received
by check or by bank wire or electronic funds transfer. To receive the
proceeds by check: the check must be made payable exactly as the account is
registered and the check must be sent to the address of record which must not
have changed in the last 30 days. To receive the proceeds by bank wire or by
electronic funds transfer: the proceeds must be sent to your bank wire
address of record which must have been properly pre-designated either on
your Account Application or on an Account Options Form and which must not
have changed in the last 30 days. To redeem by fax send your redemption
request to 1-800-225-4240. You may always elect to deliver redemption
instructions to PSC by mail. See "Telephone Transactions and Related
Liabilities" below. Telephone and fax redemptions will be priced as described
above. You are strongly urged to consult with your financial representative
prior to requesting a telephone redemption.
    

Selling Shares Through Your Broker-Dealer.   The Fund has authorized PFD to
act as its agent in the repurchase of shares of the Fund from qualified
broker-dealers and reserves the right to terminate this procedure at any
time. Your broker-dealer must receive your request before the close of
business on the Exchange and transmit it to PFD before PFD's close of
business to receive that day's redemption price. Your broker-dealer is
responsible for providing all necessary documentation to PFD and may charge
you for its services.

Small Accounts.   The minimum account value is $500. If you hold shares of
the Fund in an account with a net asset value of less than the minimum
required amount due to redemptions or exchanges, the Fund may redeem the
shares held in this account at net asset value if you have not increased the
net asset value of the account to at least the minimum required amount within
six months of notice by the Fund to you of the Fund's intention to redeem the
shares.

   
CDSC on Class A Shares.   Purchases of Class A shares of $1 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 PFD on
these investments in the event of a share redemption within 12 months
following the share purchase, at the rate of 1% of the lesser of the value of
the shares redeemed (exclusive of reinvested dividend and capital gain
distributions) or the total cost of such shares. Shares subject to the CDSC
which are exchanged into another Pioneer mutual fund will continue to be
subject to the CDSC until the original 12-month period expires. However, no
CDSC is payable upon redemption with respect to Class A shares purchased by
401(a) or 401(k) retirement plans with 1,000 or more eligible participants or
with at least $10 million in plan assets.
    

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

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

IX. HOW TO EXCHANGE FUND SHARES

   
Written Exchanges.   You may exchange your shares by sending a letter of
instruction to PSC. Your letter should include your name, the name of the
Fund out of which you wish to exchange and the name of the Pioneer mutual
fund into which you wish to exchange, your fund account number(s), the Class
of shares to be exchanged and the dollar amount or number of shares to be
exchanged. Written exchange requests must be signed by all record owner(s)
exactly as the shares are registered.
    


                                      11
<PAGE>

   
Telephone Exchanges.   Your account is automatically authorized to have the
telephone exchange privilege unless you indicate otherwise on your Account
Application or by writing to PSC. Proper account identification will be
required for each telephone exchange. Telephone exchanges may not exceed
$500,000 per account per day. Each telephone exchange request, whether by
voice or FactFone(SM), will be recorded. You are strongly urged to consult
with your financial representative prior to requesting a telephone exchange.
See "Telephone Transactions and Related Liabilities" below.

Automatic Exchanges.   You may automatically exchange shares from one Pioneer
mutual fund account for shares of the same Class in another Pioneer mutual
fund account on a monthly or quarterly basis. The accounts must have
identical registrations and the originating account must have a minimum
balance of $5,000. The exchange will be effective on the day of the month
designated on your Account Application or Account Options Form.
    

General.   Exchanges must be at least $1,000. You may exchange your
investment from one Class of Fund shares at net asset value, without a sales
charge, for shares of the same Class of any other Pioneer mutual fund. Not
all Pioneer mutual funds offer more than one Class of shares. A new Pioneer
mutual fund account opened through an exchange must have a registration
identical to that on the original account.

   
Shares which would normally be subject to a CDSC upon redemption will not be
charged the applicable CDSC at the time of an exchange. Shares acquired in an
exchange will be subject to the CDSC of the shares originally held. For
purposes of determining the amount of any applicable CDSC, the length of time
you have owned shares acquired by exchange will be measured from the date you
acquired the original shares and will not be affected by any subsequent
exchange.
    

Exchange requests received by PSC before 4:00 p.m. Eastern Time will be
effective on that day if the requirements below have been met, otherwise,
they will be effective on the next business day. PSC will process exchanges
only after receiving an exchange request in good order. There are currently
no fees or sales charges imposed at the time of an exchange. An exchange of
shares may be made only in states where legally permitted. For federal and
(generally) state income tax purposes, an exchange is considered to be a sale
of the shares of the Fund exchanged and a purchase of shares in another Fund.
Therefore, an exchange could result in a gain or loss on the shares sold,
depending on the tax basis of these shares and the timing of the transaction,
and special tax rules may apply.

   
You should consider the differences in objectives and policies of the Pioneer
mutual funds, as described in each fund's current prospectus, before making
any exchange. For the protection of the Fund's performance and shareholders,
the Fund and PFD reserve the right to refuse any exchange request or
restrict, at any time without notice, the number and/or frequency of
exchanges to prevent abuses of the exchange privilege. Such abuses may arise
from frequent trading in response to short-term market fluctuations, a
pattern of trading by an individual or group that appears to be an attempt to
"time the market," or any other exchange request which, in the view of
management, will have a detrimental effect on the Fund's portfolio management
strategy or its operations. In addition, the Fund and PFD reserve the right
to charge a fee for exchanges or to modify, limit, suspend or discontinue the
exchange privilege with notice to shareholders as required by law.
    

X. DISTRIBUTION PLANS

   
The Fund has adopted a Plan of Distribution for each Class of shares (the
"Class A Plan," "Class B Plan," and "Class C Plan") in accordance with Rule
12b-1 under the 1940 Act pursuant to which certain distribution and service
fees are paid.
    

Pursuant to the Class A Plan, the Fund reimburses PFD for its actual
expenditures to finance any activity primarily intended to result in the sale
of Class A shares or to provide services to holders of Class A shares,
provided the categories of expenses for which reimbursement is made are
approved by the Fund's Board of Trustees. As of the date of this Prospectus,
the Board of Trustees has approved the following categories of expenses for
Class A shares of the Fund: (i) a service fee to be paid to qualified
broker-dealers in an amount not to exceed 0.25% per annum of the Fund's daily
net assets attributable to Class A shares; (ii) reimbursement to PFD for its
expenditures for broker-dealer commissions and employee compensation on
certain sales of the Fund's Class A shares with no initial sales charge (See
"How to Buy Fund Shares"); and (iii) reimbursement to PFD for expenses
incurred in providing services to Class A shareholders and supporting
broker-dealers and other organizations (such as banks and trust companies) in
their efforts to provide such services. Banks are currently prohibited under
the Glass-Steagall Act from providing certain underwriting or distribution
services. If a bank was prohibited from acting in any capacity or providing
any of the described services, management would consider what action, if any,
would be appropriate.

Expenditures of the Fund pursuant to the Class A Plan are accrued daily and
may not exceed 0.25% of the Fund's average daily net assets attributable to
Class A shares. Distribution expenses of PFD are expected to substantially
exceed the distribution fees paid by the Fund in a given year. The Class A
Plan does not provide for the carryover of reimbursable expenses beyond
twelve 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 twelve months to reimburse any expense which it incurs prior to such
termination or non-continuance, provided that payments by the Fund during
such twelve-month period shall not exceed 0.25% of the Fund's average daily
net assets during such period. The Class A Plan may not be amended to
increase materially the annual percentage limitation of average net

                                      12
<PAGE>

assets which may be spent for the services described therein without approval
of the shareholders of the Fund.

   
Both the Class B and the Class C Plans provide that the Fund will pay a
distribution fee at the annual rate of 0.75% of the Fund's average daily net
assets attributable to the applicable Class of shares and will pay PFD a
service fee at the annual rate of 0.25% of the Fund's average daily net
assets attributable to that Class of shares. The distribution fee is intended
to compensate PFD for its distribution services to the Fund. The service fee
is intended to be additional compensation for personal services and/or
account maintenance services with respect to Class B or Class C shares. PFD
also receives the proceeds of any CDSC imposed on the redemption of Class B
or Class C shares.

Commissions of 4%, equal to 3.75% of the amount invested and a first year's
service fee equal to 0.25% of the amount invested in Class B shares, are paid
to broker-dealers who have selling agreements with PFD. PFD may advance to
dealers the first year service fee at a rate up to 0.25% of the purchase
price of such shares and, as compensation therefore, PFD may retain the
service fee paid by the Fund with respect to such shares for the first year
after purchase. Dealers will become eligible for additional service fees with
respect to such shares commencing in the 13th month following the purchase.

Commissions of up to 1% of the amount invested in Class C shares, consisting
of 0.75% of the amount invested and a first year's service fee of 0.25% of
the amount invested, are paid to broker-dealers who have selling agreements
with PFD. PFD may advance to dealers the first year service fee at a rate up
to 0.25% of the purchase price of such shares and, as compensation therefore,
PFD may retain the service fee paid by the Fund with respect to such shares
for the first year after purchase. 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 criteria in order
to receive service fees. PFD or its affiliates are entitled to retain all
service fees payable under the Class B or 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.
    

XI. Dividends, Distributions and Taxation

The Fund has elected to be treated, has qualified, and intends to qualify
each year as a "regulated investment company" under Subchapter M of the Code
so that it will not pay federal income taxes on income and capital gains
distributed to shareholders at least annually.

   
Under the Code, the Fund will be subject to a nondeductible 4% 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.

Each business day the Fund declares a dividend consisting of substantially
all of its net investment income (earned interest income less expenses).
Shares being purchased will begin earning dividends on the first business day
following receipt of payment for purchased shares. Shares continue to earn
dividends up to and including the date of redemption. Dividends are normally
paid on the last business day of the month or shortly thereafter.
Distributions from net short-term capital gains, if any, may be paid with
such dividends; distributions of dividends from income and/or capital gains
may also be made at such other times as may be necessary to avoid federal
income or excise tax.

Unless shareholders specify otherwise, all distributions will be
automatically reinvested in additional full and fractional shares of the
Fund. 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. Information as to the federal tax status of
distributions will be provided annually to shareholders. See "Distribution
Options" and "Directed Dividends."
    

The Fund's dividends from its net investment income, income from securities
lending, and certain net realized foreign exchange gains, and any net
short-term capital gains are taxable to shareholders as ordinary income under
the Code. Dividends from the Fund's net long-term capital gains are taxable
to shareholders as long-term capital gains under the Code, regardless of a
shareholder's holding period for his Fund shares.

   
The Fund may be subject to foreign withholding taxes or other foreign taxes
on income (possibly including, in some cases, capital gains) from certain
foreign investments, which will reduce its return from those investments. The
Fund anticipates that it generally will not qualify to pass such taxes
through to its shareholders, who will generally neither treat such taxes as
additional income nor be entitled to any foreign tax credits or deductions
with respect to such taxes.

Dividends and other distributions and the proceeds of redemptions, exchanges
or repurchases of Fund shares paid to individuals and other non-exempt payees
will be subject to 31% backup withholding of federal income tax if the Fund
is not provided with the shareholder's correct taxpayer identification number
and certification that the number is correct and the shareholder is not
subject to such backup withholding or if the Fund receives notice from the
IRS or a broker that such withholding applies. Please refer to the Account
Application for additional information.

The description above relates only to federal income tax consequences for
shareholders who are U.S. persons, i.e., U.S. citizens or residents, or U.S.
corporations, partnerships, trusts or estates and who are subject to U.S.
federal income tax. A state income (and possibly local income and/or
intangible property) tax exemption is generally available to the extent the
Fund's distributions are derived from interest on (or, in the case of
intangibles taxes, the value of its assets is
    


                                      13
<PAGE>

   
attributable to) certain U.S. government securities, provided in some states
that certain thresholds for holdings of such securities and/or reporting
requirements are satisfied. The Fund will report annually to its shareholders
the percentage of interest income earned from U.S. government securities
during the preceding year. Non-U.S. shareholders and tax-exempt shareholders
are subject to different tax treatment that is not described above.
Shareholders should consult their own tax adviser regarding this possibility
and other tax consequences under state, local and other applicable tax laws.
    

XII. SHAREHOLDER SERVICES

PSC is the shareholder services and transfer agent for shares of the Fund.
PSC, a Massachusetts corporation, is a wholly-owned subsidiary of PGI. PSC's
offices are located at 60 State Street, Boston, Massachusetts 02109, and
inquiries to PSC should be mailed to Shareholder Services, Pioneering
Services Corporation, P.O. Box 9014, Boston, Massachusetts 02205-9014. Brown
Brothers Harriman & Co. (the "Custodian") serves as the custodian of the
Fund's securities and other assets. The principal business address of the
mutual fund division of the Custodian is 40 Water Street, Boston,
Massachusetts 02109.

Account and Confirmation Statements

PSC maintains an account for each shareholder and all transactions of the
shareholder are recorded in this account. Confirmation statements showing the
details of transactions are sent to shareholders quarterly for dividend
reinvestment and Automatic Investment Plan transactions and more frequently
for other types of transactions. The Pioneer Combined Account Statement,
mailed quarterly, is available to all shareholders who have more than one
Pioneer mutual fund account.

   
Shareholders whose shares are held in the name of an investment broker-dealer
or other party will not normally have an account with the Fund and might not
be able to utilize some of the services available to shareholders of record.
Examples of services that might not be available are purchases, exchanges or
redemption of shares by mail or telephone, automatic reinvestment of
dividends and capital gains distributions, withdrawal plans, Letters of
Intention or Rights of Accumulation.
    

Additional Investments

   
You may add to your account by sending a check (minimum of $50 for Class A
shares and $500 for Class B and Class C shares) to PSC (account number and
Class of shares should be clearly indicated). The bottom portion of a
confirmation statement may be used as a remittance slip to make additional
investments. Additions to your account, whether by check or through a Pioneer
Investomatic Plan, are invested in full and fractional shares of the Fund at
the applicable offering price in effect as of the close of regular trading on
the Exchange on the day of receipt.
    

Automatic Investment Plans

   
You may arrange for regular automatic investments of $50 or more through
government/military allotments, payroll deduction or through a Pioneer
Investomatic Plan. A Pioneer Investomatic Plan provides for a monthly or
quarterly investment by means of a preauthorized electronic funds transfer or
draft drawn on a checking account. Pioneer Investomatic Plan investments are
voluntary, and you may discontinue the Plan without penalty upon 30 days'
written notice to PSC. PSC acts as agent for the purchaser, the broker-dealer
and PFD in maintaining these plans.
    

Financial Reports and Tax Information

As a shareholder, you will receive financial reports at least semi-annually.
In January of each year the Fund will mail to you information about the tax
status of dividends and distributions.

Distribution Options

Dividends and capital gains distributions, if any, will automatically be
invested in additional shares of the Fund, at the applicable net asset value
per share, unless you indicate another option on the Account Application.

   
Two other options available are (a) dividends in cash and capital gains
distributions in additional shares; and (b) all dividends and capital gains
distributions in cash. These two options are not available, however, for
retirement plans or for an account with a net asset value of less than $500.
Changes in the distribution option may be made by written request to PSC.
    

Directed Dividends

   
You may elect (in writing) to have the dividends paid by one Pioneer mutual
fund account invested in a second Pioneer mutual fund account. The value of
this second account must be at least $1,000 ($500 for Pioneer Fund or Pioneer
II). Invested dividends may be in any amount. There are no fees or charges
for this service. Retirement plan shareholders may only direct dividends to
accounts with identical registrations i.e., PGI IRA Cust for John Smith may
only go into another account registered PGI IRA Cust for John Smith.
    

Direct Deposit

   
If you have elected to take distributions, whether dividends or dividends and
capital gains, in cash, or have established a Systematic Withdrawal Plan, you
may choose to have those cash payments deposited directly into your savings,
checking or NOW bank account. You may establish this service by completing
the appropriate section on the Account Application when opening a new account
or the Account Options Form for an existing account.
    

Voluntary Tax Withholding

   
You may request (in writing) that PSC withhold 28% of the dividends and
capital gains distributions paid from your account (before any reinvestment)
and forward the amount withheld to the IRS as a credit against your federal
income taxes. This option is not available for retirement plan accounts or
for accounts subject to backup withholding.
    

Telephone Transactions and Related Liabilities

   
Your account is automatically authorized to have telephone transaction
privileges unless you indicate otherwise on your Account Application or by
writing to PSC. You may purchase, sell or exchange Fund shares by telephone.
For personal assistance, call 1-800-225-6292 between 8:00 a.m. and 9:00 p.m.
Eastern time on weekdays. See "How to Buy Fund Shares," "How to Sell Fund
Shares" and "How to Exchange Fund Shares" for more information.
Computer-assisted transactions are avail-
    


                                      14
<PAGE>

   
able to shareholders who have pre-recorded certain bank information (see
FactFone(SM)). You are strongly urged to consult with your financial
representative 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 or PFD will be responsible
for the authenticity of instructions received by telephone, therefore, you
bear the risk of loss for unauthorized or fraudulent telephone transactions.
    

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

FactFone(SM)

   
FactFone(SM) is an automated inquiry and telephone transaction system
available to Pioneer shareholders by dialing 1-800-225-4321. FactFone(SM)
allows you to obtain current information on your Pioneer mutual fund accounts
and to inquire about the prices and yields of all publicly available Pioneer
mutual funds. In addition, you may use FactFone(SM) to make computer-
assisted telephone purchases, exchanges and redemptions from your Pioneer
accounts if you have activated your PIN. Telephone purchases and redemptions
require the establishment of a bank account of record. You are strongly urged
to consult with your financial representative prior to requesting any
telephone transaction. Shareholders whose accounts are registered in the name
of a broker-dealer or other third party may not be able to use FactFone(SM).
See "How to Buy Fund Shares," "How to Exchange Fund Shares," "How to Sell
Fund Shares" and "Telephone Transactions and Related Liabilities." Call PSC
for assistance.

Systematic Withdrawal Plans

   
If your account has a total value of at least $10,000 you may establish a SWP
providing for fixed payments at regular intervals. 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 implemented. See "Waiver or Reduction of Contingent
Deferred Sales Charge" for more information. Periodic checks of $50 or more
will be sent to you, or any person designated by you, monthly or quarterly
and your periodic redemptions of shares may be taxable to you. Payments can
be made either by check or electronic transfer to a bank account designated
by you. You may also direct that withdrawal checks be paid to another person,
although if you make this designation after you have opened your account, a
signature guarantee must accompany your instructions. Purchases of Class A
shares of the Fund at a time when you have a SWP in effect may result in the
payment of unnecessary sales charges and may therefore be disadvantageous.
    

You may obtain additional information by calling PSC at 1-800-225-6292 or by
referring to the Statement of Additional Information.

Reinstatement Privilege (Class A Shares Only)

   
If you redeem all or part of your Class A shares of the Fund, you may
reinvest all or part of the redemption proceeds without a sales charge in
Class A shares of the Fund if you send a written request to PSC not more than
90 days after your shares were redeemed. Your redemption proceeds will be
reinvested at the next determined net asset value of the Class A shares of
the Fund in effect immediately after receipt of the written request for
reinstatement. You may realize a gain or loss for federal income tax purposes
as a result of the redemption, and special tax rules may apply if a
reinstatement occurs. In addition, if 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 under "How to Exchange Fund
Shares" above, you may also reinvest in certain other Pioneer mutual funds;
in this case you must meet the minimum investment requirement for each fund
you enter. The 90-day reinstatement period may be extended by PFD for periods
of up to one year for shareholders living in areas that have experienced a
natural disaster, such as a flood, hurricane, tornado or earthquake.
    

The options and services available to shareholders, including the terms of
the Exchange Privilege and the Pioneer Investomatic Plan, may be revised,
suspended, or terminated at any time by PFD or by the Fund. You may establish
the services described in this section when you open your account. You may
also establish or revise many of them on an existing account by completing an
Account Options Form, which you may obtain by calling 1-800-225-6292.

XIII. THE FUND

The Fund is an open-end diversified management investment company (commonly
referred to as a mutual fund)

                                      15
<PAGE>

organized as a Massachusetts corporation on August 16, 1978 and reorganized
as a Massachusetts business trust on December 31, 1985. The Fund will
recognize stock certificates representing shares of Pioneer Bond Fund, Inc.
issued prior to its reorganization as a Massachusetts business trust as
evidence of ownership of an equivalent number of shares of beneficial
interest. Any shareholder desiring to surrender a stock certificate to the
Fund for a share certificate representing an equivalent number of shares of
beneficial interest may do so by making a written request for the exchange to
PSC. The request must be accompanied by the surrendered stock certificate
which must be endorsed on the back exactly in the manner as the certificate
is registered.

   
The Fund has authorized an unlimited number of shares of beneficial interest
and the Trustees are authorized to create additional series of the Fund. The
Fund is not required to hold annual meetings, although special meetings may
be called for the purposes of electing or removing Trustees, changing
fundamental investment restrictions or approving a management contract. The
Trustees have the authority, without further shareholder approval, to
classify and reclassify the shares of the Fund, or any new series of the
Fund, into one or more classes. As of the date of this Prospectus, the
Trustees have authorized the issuance of three Classes of shares, designated
Class A, Class B and Class C. 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 distribution plans adopted by holders of those shares in connection
with the distribution of shares.

When issued and paid for in accordance with the terms of the Prospectus and
Statement of Additional Information, shares of the Fund are fully-paid and
non-assessable. 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 shares certificates; certificates
will not be issued for Class B or Class C shares.
    

XIV. INVESTMENT RESULTS

   
The Fund may from time to time include yield information in advertisements or
in information furnished generally to existing or proposed shareholders.
Yield information is computed in accordance with the SEC's standardized yield
formula. The calculation for all Classes is computed by dividing the net
investment income per share of a Class during a base period of 30 days, or
one month, by the maximum offering price per share of the applicable Class of
the Fund on the last day of such base period. The resulting "30-day yield" is
then annualized as described below. Net investment income per share of a
Class is determined by dividing the Fund's net investment income attributable
to a Class during the base period by the average number of shares of that
Class of the Fund. The 30-day yield is then "annualized" by a computation
that assumes that the net investment income per share of a Class is earned
and reinvested for a six-month period at the same rate as during the 30-day
base period and that the resulting six-month income will be generated over an
additional six months.

The average annual total return (for a designated period of time) on an
investment in the Fund may be included in advertisements, and furnished to
existing or prospective shareholders. The average annual total return for
each Class is computed in accordance with the SEC's standardized formula. The
calculation for all Classes assumes the reinvestment of all dividends and
distributions at net asset value and does not reflect the impact of federal
or state income taxes. In addition, for Class A shares the calculation
assumes the deduction of the maximum sales charge of 4.50%; for Class B and
Class C shares the calculation reflects the deduction of any applicable CDSC.
The periods illustrated would normally include one, five and ten years (or
since the commencement of the public offering of the shares of a Class, if
shorter) through the most recent calendar quarter.
    

One or more additional measures and assumptions, including but not limited to
historical total returns; distribution returns; results of actual or
hypothetical investments; changes in dividends, distributions or share
values; or any graphic illustration of such data may also be used. These data
may cover any period of the Fund's existence and may or may not include the
impact of sales charges, taxes or other factors.

   
Other investments or savings vehicles and/or unmanaged market indices,
indicators of economic activity or averages of mutual fund results may be
cited or compared with the investment performance of the Fund. Rankings or
listings by magazines, newspapers or independent statistical or rating
services, such as Lipper Analytical Services, Inc., may also be referenced.

The Fund's investment results will vary from time to time depending on market
conditions, the composition of the Fund's portfolio and operating expenses of
the Fund. All quoted investment results are historical and should not be
considered representative of what an investment in the Fund may earn in any
future period. For further information about the calculation methods and uses
of the Fund's investment results, see the Statement of Additional
Information.

1.       INVESTMENT POLICIES AND RESTRICTIONS

   
         The  Fund's  Prospectus  presents  the  investment  objectives  and the
principal investment policies of the Fund.  Additional investment policies and a
further  description of some of the policies  described in the Prospectus appear
below.  Capitalized terms not otherwise defined herein have the meaning given to
them in the Prospectus.

         The following  policies and  restrictions  set forth under  "Investment
Restrictions" supplement those discussed in the Prospectus.  Except with respect
to the policy on borrowing  described  below,  whenever an investment  policy or
restriction  states  a  maximum  percentage  of the  Fund's  assets  that may be
invested in any security or presents a policy regarding quality standards,  this
standard or other  restrictions  shall be determined  immediately after and as a
result of the Fund's  investment.  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
investment objectives and policies, other than the policy on borrowing.
    

Lending of Portfolio Securities

         The Fund may lend portfolio  securities to member firms of the New York
Stock Exchange (the  "Exchange"),  under agreements which would require that the
loans be secured  continuously by collateral in cash, cash equivalents or United
States  ("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  would
continue to receive the  equivalent  of the  interest or  dividends  paid by the
issuer on 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 their 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 which
have been  approved  in  advance  by the Fund's  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.  The
Fund did not lend  portfolio  securities  during the last fiscal year and has no
present intention to engage in any material securities lending in the future.

Mortgage-Backed Securities

Multiple-Class Pass-through Securities and Collateralized Mortgage Obligations

         The Fund may invest in collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduit ("REMIC")  pass-through or participation
certificates, which may be issued by, among others, U.S. Government agencies and
instrumentalities  as well as private


                                      -2-
<PAGE>

lenders.  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 certificates of the Government National Mortgage  Association,
the Federal  National  Mortgage  Association,  or the Federal Home Loan Mortgage
Corporation  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.

Risk Factors Associated with Mortgaged-Backed Securities

         The value of an investment in fixed rate obligations can be expected to
rise as interest  rates decline and decline as interest rates rise. In contrast,
as interest  rates on  adjustable  rate mortgage  loans are reset  periodically,
yields on investments in such loans will gradually  align  themselves to reflect
changes in market  interest  rates,  causing  the value of such  investments  to
fluctuate less dramatically in response to interest rate fluctuations than would
investments in fixed rate obligations.

         The yield characteristics of Mortgage-Backed  Securities, such as those
in which the Fund may invest,  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, 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  prepayment 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  or agency  guarantee.  When the Fund  reinvests  amounts
representing payments and unscheduled prepayments of principal, it may receive 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.


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  Statement  of  Additional
Information,  such approval  means the approval of the lesser of (i) the


                                      -3-
<PAGE>

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

         The Fund may not:

                  (1)  purchase any security  (other than  securities  issued or
guaranteed  by the U.S.  Government  or its agencies or  instrumentalities)  if,
immediately  after and as a result of such  investment,  (a) more than 5% of the
value of the Fund's total assets would be invested in  securities of the issuer;
(b) the Fund would hold more than 10% of the voting securities of the issuer; or
(c) more than 25% of the  value of the  Fund's  assets  would be  invested  in a
single  industry  (each  of the  electric  utility,  natural  gas  utility,  and
telephone  industries  shall  be  considered  as a  separate  industry  for this
purpose);

                  (2) buy or sell  real  estate  in the  ordinary  course of its
business;  provided,  however,  the Fund may invest in readily  marketable  debt
securities  secured by real estate or interests  therein or issued by companies,
including  real  estate  investment  trusts,  which  invest  in real  estate  or
interests therein;

                  (3) buy or sell  commodities  or  commodity  contracts  except
interest rate futures  contracts,  options on  securities,  securities  indices,
currency and other  financial  instruments,  futures  contracts  on  securities,
securities indices, currency and other financial instruments and options on such
futures  contracts,   forward  foreign  currency  exchange  contracts,   forward
commitments,  securities index put or call warrants,  interest rate swaps,  caps
and floors and repurchase  agreements entered into in accordance with the Fund's
investment policies;

                  (4)  underwrite any issue of securities;

                  (5) make loans in an aggregate  amount in excess of 10% of the
value of the Fund's total assets,  taken at the time any loan is made,  provided
that (i) the  purchase  of debt  securities  pursuant  to the Fund's  investment
objectives shall not be deemed loans for the purposes of this restriction,  (ii)
loans of portfolio securities as described, from time to time, under "Lending of
Portfolio  Securities"  shall be made  only in  accordance  with the  terms  and
conditions  therein  set  forth and  (iii) in  seeking  a return on  temporarily
available cash, the Fund may engage in repurchase  transactions  maturing in one
week or less and involving  obligations of the U.S. Government,  its agencies or
instrumentalities;

                  (6) sell securities short,  except to the extent that the Fund
contemporaneously  owns  or has the  right  to  acquire  at no  additional  cost
securities identical to those sold short;

                  (7)  purchase securities on margin;

                  (8) borrow  money,  except  that,  as a temporary  measure for
extraordinary or emergency  purposes and not for investment  purposes,  the Fund
may  borrow  up to 5% of the  value  of its  total  assets  at the  time  of the
borrowing; or

                                      -4-
<PAGE>

                  (9)  mortgage, pledge, or hypothecate any of its assets.

         Non-fundamental  Investment  Restrictions.  The following  restrictions
have 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:

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

                  (2)  knowingly   purchase   securities  of  other   registered
investment  companies,  except  in  connection  with  a  merger,  consolidation,
acquisition, or reorganization;

                  (3) invest in any security, including any repurchase agreement
maturing in more than seven  days,  which is  illiquid,  if more than 15% of the
total  assets of the Fund,  taken at market  value,  would be  invested  in such
securities;

                  (4) purchase or retain the securities of any issuer,  if those
individual  officers  and  trustees  or  directors  of the Fund,  its adviser or
principal underwriter,  each owning beneficially more than one half of 1% of the
securities of such issuer,  together own more than 5% of the  securities of such
issuer; or

                  (5) invest more than 5% of its total assets in  securities  of
companies having, together with their predecessors,  a record of less than three
years of continuous operation.

         It is the  policy of the Fund not to  concentrate  its  investments  in
securities of companies in any particular  industry or group of  industries.  In
the opinion of the staff of the Securities and Exchange  Commission (the "SEC"),
investments  are  concentrated  in a  particular  industry  if such  investments
aggregate 25% or more of the Fund's total  assets.  The Fund has agreed to abide
by the foregoing  non-  fundamental  policy which it will not change without the
affirmative  vote of a majority of the Fund's  outstanding  shares of beneficial
interest.

         In connection with the offering of its shares in various  states,  as a
matter of  non-fundamental  investment policy, the Fund has agreed not to invest
in puts, calls,  straddles,  spreads or any combination  thereof, in oil, gas or
other mineral  leases,  exploration or development  programs,  or in real estate
limited partnerships.

Other Policies and Risks

         The Fund may invest up to 15% of its assets in foreign  securities  and
up to 5% of  its  assets  in  foreign  securities  which  are  not  listed  on a
recognized  foreign or domestic  exchange,  provided that  purchases of Canadian
securities are not subject to the  limitations in this  paragraph.  Investing in
securities of foreign  companies and countries  involves certain  considerations
and risks which are not typically  associated with investing in U.S.  government
securities and those of


                                      -5-
<PAGE>

domestic  companies.  Foreign  companies  are not  generally  subject to uniform
accounting,  auditing and  financial  standards and  requirements  comparable to
those  applicable  to  U.S.  companies.   There  may  also  be  less  government
supervision and regulation of foreign securities  exchanges,  brokers and listed
companies than exists in the United States.

         Interest  paid by foreign  issuers  may be subject to  withholding  and
other  foreign  taxes which may decrease the net return on such  investments  as
compared  to  interest  paid to the Fund by the U.S.  government  or by domestic
companies.  In  addition,  there  may  be  the  possibility  of  expropriations,
confiscatory taxation,  political,  economic or social instability or diplomatic
developments  which could affect  assets of the Fund held in foreign  countries.
The value of foreign securities may be adversely affected by fluctuations in the
relative rates of exchange  between the  currencies of different  nations and by
exchange control regulations.  There may be less publicly available  information
about  foreign  companies  and  governments  compared  to  reports  and  ratings
published about U.S.  companies.  Foreign  securities markets have substantially
less volume than domestic  markets and securities of some foreign  companies are
less liquid and more volatile than securities of comparable U.S.
companies.

2.       MANAGEMENT OF THE FUND

         The  Fund's  Board of  Trustees  provides  broad  supervision  over the
affairs of the Fund.  The  officers of the Fund are  responsible  for the Fund's
operations.  The Trustees and  executive  officers of the Fund are listed below,
together  with  their  principal  occupations  during  the past five  years.  An
asterisk  indicates those Trustees who are interested persons of the Fund within
the meaning of the Investment Company Act of 1940, as amended (the "1940 Act").

3.       INVESTMENT ADVISER

         The  Fund  has   contracted   with  PMC,  60  State   Street,   Boston,
Massachusetts, to act as its investment adviser. The term of the contract is one
year, but it is renewable  annually after such date by the vote of a majority of
the Board of Trustees of the Fund (including a majority of the Board of Trustees
who are not parties to the contract or  interested  persons of any such parties)
cast in person at a meeting  called for the  purpose of voting on such  renewal.
This contract  terminates if assigned and may be terminated  without  penalty by
either  party by vote of its  Board of  Directors  or  Trustees  or by vote of a
majority of outstanding  voting securities and the giving of sixty days' written
notice.  Pursuant  to the  management  contract,  PMC 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 PMC. PMC, however,  is not protected against
liability by reason of wilful 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 respective management contract.

   
         As compensation for its management services and expenses incurred,  PMC
is  entitled  to a  management  fee at the rate of 0.50% per annum of the Fund's
average daily net assets.  The fee is normally  computed daily and paid monthly.
During  its  1996,  1995 and 1994  fiscal  years,  the Fund  paid or owed  total
management  fees  to PMC  of  approximately  $588,432,  $546,000  and  $571,000,
respectively.
    

 4.      UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

         The Fund has  entered  into an  Underwriting  Agreement  with PFD.  The
Underwriting  Agreement will continue from year to year if annually  approved by
the  Trustees.  The  Underwriting  Agreement  provides  that PFD  will  bear any
distribution expenses not borne by the Fund.

         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.
The  Fund  and  PFD  have  agreed  to  indemnify  each  other  against   certain
liabilities, including liabilities under the Securities Act of 1933, as amended.
Under the  Underwriting  Agreement,  PFD will use its best  efforts in rendering
services to the Fund.

   
         The Fund has  adopted a plan of  distribution  pursuant  to Rule  12b-1
under the 1940 Act with  respect  to Class A,  Class B and  Class C shares  (the
"Class A  Plan,"  the  "Class B Plan"  and the  "Class C Plan")  (together,  the
"Plans").
    

                                      -11-
<PAGE>

         Class A Plan

         Pursuant  to the  Class  A Plan  the  Fund  may  reimburse  PFD for its
expenditures in financing any activity  primarily intended to result in the sale
of Fund shares.  Certain  categories of such  expenditures have been approved by
the Board of Trustees  and are set forth in the  Prospectus.  See  "Distribution
Plans" in the Prospectus.  The expenses of the Fund pursuant to the Class A Plan
are accrued on a fiscal year basis and may not exceed,  with  respect to Class A
shares,  the  annual  rate of 0.25% of the  Fund's  average  annual  net  assets
attributable to Class A.

         Class B Plan

         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.  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.  Dealers will become eligible for additional  service
fees with respect to such shares  commencing in the thirteenth  month  following
purchase.  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  to  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  CDSC's  attributable  to  Class  B  shares.  (See
"Distributions Plans" in the Prospectus.)

   
Class C Plan

         The  Class C Plan  provides  that a 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
    


                                      -12-
<PAGE>

   
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  therefore,  PFD may
retain the  service  fee paid by the Fund with  respect  to such  shares for the
first year after  purchase.  Commencing  in the  thirteenth  month  following  a
purchase of Class C shares,  dealers will become eligible for additional service
fees at a rate of up to 0.25% of the amount invested and additional compensation
at a rate of up to 0.75% of the net asset  value with  respect  to 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 the 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. (See "Distribution Plans" in the Prospectus.)
    

         General

         In accordance with the terms of the Plans, PFD provides to the Fund for
review by the Trustees a quarterly  written report of the amounts expended under
the respective  Plan and the purpose for which such  expenditures  were made. In
the Trustees'  quarterly  review of the Plans,  they will consider the continued
appropriate  ness 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.

         The Plans were  adopted by a  majority  vote of the Board of  Trustees,
including  all of the Trustees who are not, and were not at the time they voted,
interested  persons of the Fund, as defined in the 1940 Act (none of whom had or
have any direct or indirect  financial  interest in the operation of the Plans),
cast in person at a meeting  called for the  purpose of voting on the Plans.  In
approving  the  Plans,  the  Trustees  identified  and  considered  a number  of
potential  benefits which the Plans may provide.  The Board of Trustees believes
that there is a reasonable  


                                      -13-
<PAGE>

likelihood  that the Plans  will  benefit  the Fund and its  current  and future
shareholders.  Under their  terms,  the Plans remain in effect from year to year
provided such  continuance  is approved  annually by vote of the Trustees in the
manner described above. 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 in the manner  described  above.  A Plan may be  terminated  at any
time,  without  payment of any penalty,  by vote of the majority of the Trustees
who are not  interested  persons  of the  Fund and have no  direct  or  indirect
financial  interest in the operations of the Plan, or by a vote of a majority of
the  outstanding  voting  securities  of the  respective  Class  of the Fund (as
defined in the 1940 Act).  A Plan will  automatically  terminate in the event of
its assignment (as defined in the 1940 Act).

   
         During the fiscal  year ended June  30,1996,  the Fund  incurred  total
distribution fees pursuant to the Fund's Class A Plan, Class B Plan, and Class C
Plan  respectively,  as follows:  $248,056,  $119,908 and $789. The distribution
fees  were  paid by the Fund to PFD in  reimbursement  of  expenses  related  to
servicing  of  shareholder  accounts  and  to  compensating  dealers  and  sales
personnel.

         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 of 4% of the
lower of the cost or market  value of the shares and Class C shares are  subject
to a 1% CDSC.  During the fiscal year ended June 30, 1996,  CDSCs, in the amount
of  approximately  $34,000 were paid to PFD in reimbursement of expenses related
to servicing of  shareholders'  accounts  and  compensation  paid to dealers and
sales personnel.
    

5.       SHAREHOLDER SERVICING/TRANSFER AGENT

         The  Fund  has   contracted   with  PSC,  60  State   Street,   Boston,
Massachusetts  02109,  to act as shareholder  servicing agent and transfer agent
for the Fund. This contract terminates if assigned and may be terminated without
penalty  by either  party by vote of its Board of  Directors  or  Trustees  or a
majority of its  outstanding  voting  securities  and the giving of ninety days'
written notice.

         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 Fund portfolio  accounts;  and (iii) maintaining account records
and responding to routine shareholder inquiries.

   
         PSC  receives  an annual  fee of $28.00  for each  Class A, Class B and
Class C  shareholder  account  from the Fund as  compensation  for the  services
described above.  This fee is set at an amount  determined by vote of a majority
of the Fund's Trustees (including a majority of the Trustees who are not parties
to the  contract  with PSC or  interested  persons  of any such  parties)  to be
comparable to fees for such services being paid by other  investment  companies.
The Fund may  compensate  entities  which  have  contracted  to be an agent  for
specific  transaction  processing  and  services.  Any such payments by the Fund
would be in lieu of the per  account fee which
    


                                      -14-
<PAGE>

would otherwise be paid by the Fund to PSC.

6.       CUSTODIAN

         Brown  Brothers  Harriman & Co.  (the  "Custodian"),  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.  The  Custodian  does not
determine the  investment  policies of the Fund or decide which  securities  the
Fund will buy or sell. The Fund may,  however,  invest in securities,  including
repurchase  agreements,  issued by the Custodian and may deal with the Custodian
as principal in securities  transactions.  Portfolio securities may be deposited
into the Federal Reserve-Treasury Department Book Entry System or the Depository
Trust Company.

7.       PRINCIPAL UNDERWRITER

   
         PFD,  60 State  Street,  Boston,  Massachusetts  02109,  serves  as the
principal underwriter for the Fund. During the Fund's 1996, 1995 and 1994 fiscal
years,  net  underwriting  commissions  earned  by PFD in  connection  with  its
offering  of Fund  shares  were  approximately  $39,000,  $39,000  and  $66,000,
respectively.  Commissions reallowed to dealers by PFD in those three years were
approximately $281,000, $268,000 and $492,000,  respectively. See "Underwriting
Agreement and  Distribution  Plan" above for a  description  of the terms of the
Underwriting Agreement with PFD.
    

         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 an  acquisition  of portfolio
securities  (other than  municipal  debt  securities  issued by state  political
subdivisions  or their  agencies or  instrumentalities)  pursuant to a bona fide
purchase of assets,  merger or other reorganization  provided (i) the securities
meet the investment objectives and policies of the Fund; (ii) the securities are
acquired by the Fund for investment and not for resale;  (ii) the securities are
not restricted as to transfer either by law or liquidity of market; and (iv) the
securities have a value which is readily ascertainable (and not established only
by  evaluation  procedures)  as  evidenced  by a listing on the  American  Stock
Exchange or the New York Stock Exchange or by quotation under the NASD Automated
Quotation  System. An exchange of securities for Fund shares will generally be a
taxable transaction to the shareholder.

8.       INDEPENDENT PUBLIC ACCOUNTANTS

         Arthur Andersen LLP, One  International  Place,  Boston,  Massachusetts
02110, are 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 


                                      -15-
<PAGE>

by PMC pursuant to authority  contained in the management  contract.  Securities
purchased and sold on behalf of the Fund normally will be traded in the over-the
counter market on a net basis (i.e. without  commission)  through dealers acting
for their own  account  and not as brokers  or  otherwise  through  transactions
directly with the issuer of the  instrument.  Some  securities are purchased and
sold on an exchange or in over-the-counter  transactions  conducted on an agency
basis involving a commission.  The primary  consideration  in placing  portfolio
security  transactions is execution at the most favorable prices.  Additionally,
in selecting  brokers or dealers,  PMC will consider 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; the
reasonableness  of any dealer  spreads;  and the dealer's  sale of shares of the
Fund or other Pioneer mutual funds.

         PMC may select dealers which provide brokerage and/or research services
to the Fund and/or other investment  companies  managed by PMC.  Consistent with
Section 28(e) of the Securities  Exchange Act of 1934, as amended,  the Fund may
pay  commissions  to such  broker-dealers  in an amount  greater than the amount
another firm might charge as compensation for such services if PMC determines in
good faith  that the amount of the  commissions  charged by a  broker-dealer  is
reasonable  in relation to the  services  provided by such  broker-dealer.  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 price
quotation services; furnishing analyses, manuals and reports concerning issuers,
industries,   securities,  economic  factors  and  trends,  portfolio  strategy,
performance of accounts,  comparative  fund statistics and credit rating service
information;  and effecting  securities  transactions  and performing  functions
incidental  thereto (such as clearance and settlement).  PMC maintains a listing
of broker-dealers who provide such services on a regular basis. However, because
it is  anticipated  that  many  transactions  on  behalf  of the Fund and  other
investment  companies managed by PMC 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 broker-  dealers  solely  because such services were  provided.
Management  believes  that no exact  dollar  value  can be  calculated  for such
services.

         The  research  received  from dealers may be useful to PMC in rendering
investment  management  services  to the Fund  and  other  investment  companies
managed by PMC, and conversely,  such information provided by brokers or dealers
who have executed  transaction orders on behalf of such other PMC clients may be
useful to PMC in carrying out its  obligations  to the Fund. The receipt of such
research has not reduced PMC's normal independent research activities;  however,
it  enables  PMC 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 or accounts
managed by PMC. This policy does not imply a commitment to execute all portfolio
transactions through all broker-dealers that sell 


                                      -16-
<PAGE>

shares of the Fund.

         The   Trustees   periodically   review   PMC's   performance   of   its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Fund.

         In addition to the Fund, PMC acts as investment adviser to other mutual
funds in the  Pioneer  group and private  accounts  with  investment  objectives
similar to those of the Fund. As such, securities may meet investment objectives
of the Fund,  such other funds and such  private  accounts.  In such cases,  the
decision to recommend a purchase for 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 company presently has in a
particular  industry or country and the availability of investment funds in each
company.

         It is possible  that, at times,  identical  securities  will be held by
more than one fund and/or account.  However, the position of any fund or account
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 the Fund,  another  mutual fund in the Pioneer  group or a private  account
managed by PMC 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 PMC 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 account,  the  resulting  participation  in volume  transactions  could
produce better executions for the Fund or other account.  In the event that 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.

10.      TAX STATUS

         It is the Fund's policy to meet the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended (the "Code"),  for  qualification as a
regulated  investment  company.  These requirements relate to the sources of its
income, the diversification of its assets and the timing of its distributions to
shareholders.  If the Fund meets all such  requirements  and  distributes to its
shareholders, in accordance with the Code's timing requirements,  all investment
company taxable income and net capital gain, if any, which it receives, the Fund
will be relieved of the necessity of paying  federal income tax. The Fund is not
subject to Massachusetts  corporate excise or franchise taxes and, provided that
it qualifies as a regulated  investment company for federal income tax purposes,
it will not be required to pay any Massachusetts income tax.

         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  


                                      -17-
<PAGE>

exchange  gains,  are taxable as ordinary  income,  whether  received in cash or
reinvested in additional  shares.  Dividends from net long-term  capital gain in
excess of net  short-term  capital  loss,  if any,  whether  received in cash or
additional shares,  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.  Because none of the
Fund's income is expected to arise from dividends,  no part of the distributions
to its corporate shareholders will qualify for the dividends-received  deduction
for corporations.

         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,  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.

         If the Fund invests in certain payment-in-kind  securities, zero coupon
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 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.

         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. Consequently,  subsequent distributions from such appreciation
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 in reality represent a return of a portion
of the investment.

         Any loss  realized  upon the  redemption  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 at net asset value pursuant
to the  reinvestment  privilege,  the sales  charge  paid on such  shares is not
included in their tax basis under the Code,  and (2) in the case of an exchange,
all or a portion of the sales  charge  paid on such  shares is not  included  in

                                      -18-
<PAGE>

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  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
certain  redemptions  may be disallowed  under "wash sale" rules in the event of
other  investments  in the Fund  within a period  of 61 days  beginning  30 days
before and ending 30 days after a redemption or other sale of shares.

   
         For Federal income tax purposes, the Fund is permitted to carry forward
a net capital loss in any year to offset 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 June
30, 1996,  the Fund had a net capital loss carry  forward of  $3,200,964,  which
will expire between 1998 and 2004 if not utilized.
    

         The Fund may be  subject  to  withholding  and other  taxes  imposed by
foreign  countries  with  respect to its  investments  in those  countries.  Tax
conventions  between certain countries and the U.S. may reduce or eliminate such
taxes.  The Fund does not expect to satisfy the requirements for passing through
to  shareholders  their pro rata shares of foreign taxes paid by the Fund,  with
the result that  shareholders will not include such taxes in their gross incomes
(in addition to dividends  actually  received) and will not be entitled to a tax
deduction or credit for such taxes on their own tax returns.

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

   
         Federal law requires that the Fund withhold 31% of reportable payments,
including  dividends,  capital gain  dividends  and the proceeds of  redemptions
(including  exchanges) and  repurchases,  to shareholders  who have not complied
with  IRS  regulations.   In  order  to  avoid  this  withholding   requirement,
shareholders must certify on their Applications,  or on separate W-9 Forms, 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.
    

         The  description   above  relates  only  to  U.S.  federal  income  tax
consequences  for  shareholders  who are U.S.  persons,  i.e., U.S.  citizens or
residents  or U.S.  corporations,  partnerships,  trusts or estates  and who are
subject to U.S.  federal income tax.  Investors  other than U.S.  persons may be
subject  to  different  U.S.  tax  treatment,  including  a  possible  30%  U.S.
withholding  tax (or  withholding tax at a lower treaty rate) on amounts treated
as ordinary  dividends  from the Fund and,  unless an effective  IRS Form W-8 or
authorized  substitute  is on file, to 31% backup  withholding  on certain other
payments from the Fund. The description 


                                      -19-
<PAGE>

above also does not address  special tax rules that may be applicable to certain
classes of investors,  such as tax-exempt  entities,  insurance  companies,  and
financial  institutions.  Shareholders  should consult their own tax advisors on
these matters and on state, local and other applicable tax laws.

11.      DESCRIPTION OF SHARES

   
         The  Fund's  Declaration  of Trust  permits  its Board of  Trustees  to
authorize the issuance of an unlimited  number of full and fractional  shares of
beneficial  interest (without par value) which may be divided into such separate
series as the Trustees may  establish.  The  Trustees may  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  of Trust  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,  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 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 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 the Fund vote together as a class on matters
that affect the Fund in substantially the same manner. As to matters affecting a
single class, shares of such class will vote separately.

         Although  Trustees  are  not  elected  annually  by  the  shareholders,
shareholders  have under certain  circumstances  the right to remove one or more
Trustees.  No amendment that adversely affects the rights of shareholders may be
made to the  Fund's  Declaration  of Trust  without  the  affirmative  vote of a
majority of its shares.  Shares have no preemptive  or conversion  rights except
that under certain  circumstances  Class B shares may convert to Class A shares.
Shares are fully paid and non-assessable by the Fund, except as set forth below.
See "Certain Liabilities."

12.      CERTAIN LIABILITIES

         As a Massachusetts  business trust, the Fund's  operations are governed
by its  Declaration  of Trust dated December 7, 1993, a copy of which is on file
with the office of the Secretary of State of The Commonwealth of  Massachusetts.
Theoretically, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held  personally  liable  for the  obligations  of the trust.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability  for acts or  obligations  of the Fund or any  series  of the Fund and
provides that notice of such disclaimer be given in each  agreement,  obligation
or instrument  entered into or executed by


                                      -20-
<PAGE>

the Fund or its Trustees.  Moreover,  the  Declaration of Trust 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.  The  Declaration of
Trust also 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
would be limited to  circumstances  in which the Fund  itself  will be unable to
meet its  obligations.  In light of the  nature of the Fund's  business  and the
nature and  amount of its  assets,  the  possibility  of the Fund's  liabilities
exceeding its assets, and therefore a shareholder's risk of personal  liability,
is remote.

         The Declaration of Trust 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 of Trust 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.

13.      DETERMINATION OF NET ASSET VALUE

         The net asset  value per share of each class of the Fund is  determined
as of the close of regular trading on the Exchange (currently 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, 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 in which the  level of  trading  in its  portfolio
securities  is  sufficiently  high so that the current net asset value per share
might  be  materially  affected  by  changes  in  the  value  of  its  portfolio
securities.  On any day in which no  purchase  orders for the shares of the Fund
become effective and no shares are tendered for redemption,  the net asset value
per share is not required to be determined.

         The net asset  value per share of each class of the Fund is computed by
taking the value of all of its assets, less the Fund's liabilities, attributable
to the class, and dividing it by the number of outstanding  shares of the class.
The Board of Trustees  has  directed  that the fair  market  value of the Fund's
assets  should  be  determined  as  follows.  Ordinarily,  investments  in  debt
securities are valued on the basis of information furnished by a pricing service
which  utilizes  primarily  a matrix  system  (which  reflects  such  factors as
security  prices,  yields,  maturities and ratings),  supplemented by dealer and
exchange  quotations,  to recommend  valuations  for normal  institutional-sized
trading units of debt securities. In addition, the Board has instructed advisory
personnel  not to rely  exclusively  on this pricing  service if the fair market
value of certain  securities may be more  accurately  determined on the basis of
information available from other sources.  Temporary cash investments are valued
at cost, which approximates market value.

         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.
    

14.      SYSTEMATIC WITHDRAWAL PLAN

   
         The  Systematic  Withdrawal  Plan  ("SWP")  is  designed  to  provide a
convenient  method of receiving fixed payments at regular  intervals from shares
of the Fund  deposited  by the  applicant  under this SWP.  The  applicant  must
deposit or purchase for deposit with PSC shares of the Fund having a total value
of not less than $10,000.  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
implemented.  Periodic  checks of $50 or more will be sent to the applicant,  or
any person designated by him, monthly or quarterly.

         Any income dividends or capital gains distributions on shares under the
SWP  will be  credited  to the  SWP  account  on the  payment  date in full  and
fractional shares at the net asset value per share in effect on the record date.
    

         SWP  payments are made from the  proceeds of the  redemption  of shares
deposited  under the SWP in a SWP account.  To the extent that such  redemptions
for periodic  withdrawals  exceed dividend income reinvested in the SWP account,
such  redemptions  will reduce and may  ultimately  exhaust the number of shares
deposited in the Plan account.  Share redemptions are taxable transactions,  and
in addition the amounts  received by a  shareholder  cannot be  considered as an
actual yield or income on his or her  investment  because part of such  payments
may be a return of his or her investment.

         The 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  under  the Plan  have  been
redeemed.  The fees of PSC for maintaining  Systematic Withdrawal Plans are paid
by the Fund.

15.      LETTER OF INTENTION

         Purchases  of  $100,000  or  over  of  Class A  shares  (excluding  any
reinvestments  of  dividends  and  capital  gains  distributions)  made within a
13-month period  pursuant to a Letter of Intention  provided by PFD will qualify
for a reduced  sales  charge.  Such reduced sales charge will be the charge that
would be applicable to the purchase of all Class A shares  purchased during such
13-month period pursuant to a Letter of Intention had such shares been purchased
all at once.  See "How to Buy Fund Shares" in the  Prospectus.  For  example,  a
person who signs a Letter of Intention  providing for a total investment in Fund
shares of $100,000  over a 13-month  period  would be charged at the 3.50% sales
charge rate with respect to all purchases during that period.  Should the amount
actually  purchased  during  the  13-month  period  be more or  less  than  that
indicated  in the Letter,  an  adjustment  in the sales  charge will be made.  A
purchase not made pursuant to a Letter of Intention  may be included  thereafter
if the Letter is filed within 90 days of such purchase. Any shareholder may also
obtain the reduced  sales  charge by  including  the value 


                                      -22-
<PAGE>

(at current  offering  price) of all shares of record held in the Fund and other
Pioneer  mutual  funds as of the date of the  Letter  of  Intention  as a credit
toward  determining the applicable  scale of sales charge for the Class A shares
to be purchased under the Letter of Intention.

         The  Letter  of  Intention  authorizes  PSC to escrow  shares  having a
purchase price equal to 5% of the stated  investment in the Letter of Intention.
A Letter of Intention is not a binding obligation upon the investor to purchase,
or the Fund to sell, the full amount  indicated and the investor should read the
provisions  of the Letter of  Intention  contained  in the  Account  Application
carefully before signing.

16.      INVESTMENT RESULTS

         The Fund's yield quotations and average annual total return  quotations
as they may appear in the Prospectus,  this Statement of Additional  Information
or in  advertising  and sales  literature  are  calculated  by standard  methods
prescribed by the SEC.

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 other relevant indices.  For example, the Fund may compare a
class's  yield  and/or total return to the  Shearson  Lehman  Hutton  Government
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 indices or indicators of
economic activity,  e.g., inflation or interest rates.  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, Personal Investor,  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 such publications) or used for comparison, as
well as performance  listings and rankings from various other sources  including
CDA/Weisenberger  Investment Companies Service,  Donoghue's Mutual Fund Almanac,
Investment  Company Data, Inc.,  Ibbotson  Associates,  Johnson's Charts,  Kanon
Block Carre and Co., Lipper Analytical Services,  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 Fund shareholders.

         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 the
class,  over  any  period  up  to  the  lifetime  of  the  class.  Total  return
calculations  will usually assume the  reinvestment of all dividends and capital

                                      -23-
<PAGE>

gains  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 may 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.

         In  representing  investment  results  of a  class,  the  Fund may also
include  references to certain  financial  planning  concepts,  including (a) an
investor's  need to evaluate  his or her  financial  assets and  obligations  to
determine how much to invest;  (b) the need to analyze the objectives of various
investments to determine where to invest; and (c) the need to analyze his or her
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's 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
                           YIELD  = 2[ ( ----- +1)6-1]
                                            cd

Where:            a          =      interest earned during the period

                  b          =      net expenses accrued for the period

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

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

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

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

                                      -24-
<PAGE>

         (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 on a remaining  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 discount or premium
on a remaining 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 a class
accrued during any base period, if any, pursuant to the respective  Distribution
Plan are included among the expenses accrued during the base period.

   
         The Fund's yield for the 30 days ended June 30, 1996, computed as above
was 5.84% for  Class A  shares,  5.15% for Class B shares  and 5.27% for Class C
shares.
    

Standardized Average Annual Total Return Quotations

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

                P(1+T)n  =   ERV

   
       Where:            P       =        a  hypothetical   initial  payment  of
                                          $1000,  less the maximum sales load of
                                          $45  for   Class  A   shares   or  the
                                          deduction  of the  CDSC on  Class B or
                                          Class  C  shares  at  the  end  of the
                                          period.
    

                         T       =        average annual total return

                                      -25-
<PAGE>

                         n       =        number of years

                         ERV     =        ending   redeemable   value   of   the
                                          hypothetical   $1000  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 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 Fund's mean account size.

The total returns for each Class of shares of the Fund as of June 30, 1996,  are
as follows:

                         Average Annual Total Return (%)
                           One Year   Five Years     Ten Years  Since Inception*
Class A Shares              -0.66        6.86           7.34         8.90
Class B Shares              -0.73         N/A           N/A          4.46
Class C Shares               N/A          N/A           N/A         -3.95

* Inception  was October 31, 1978 for Class A shares and April 4, 1994 for Class
B shares. Class C Shares were first offered January 31, 1996.

                          Description of Bond Ratings1

   
                        Moody's Investors Service, Inc.2
    

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
edge." 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 risks appear somewhat bigger than in 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 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.

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

2 Rates bonds of issuers  which have  $600,000 or more of debt,  except bonds of
educational  institutions,  projects  under  construction,  enterprises  without
established  earnings  records and  situations  where current  financial data is
unavailable.



                                      -28-
<PAGE>



                        Standard & Poor's Ratings Group 3

AAA:  Bonds rated AAA are highest grade  obligations.  This rating  indicates an
extremely strong capacity to pay principal and interest.

AA: Bonds rated AA also  qualify as  high-quality  obligations.  Capacity to pay
principal  and  interest is very strong,  and in the majority of instances  they
differ from AAA issues only in small degree.

A: Bonds rated A have a strong capacity to pay principal and interest,  although
they are more susceptible to the adverse effects of changes in circumstances and
economic conditions.

BBB:  Bonds  rated  BBB are  regarded  as  having an  adequate  capacity  to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

- -------------------------------------------------
3 Rates all governmental  bodies having  $1,000,000 or more of debt outstanding,
unless adequate information is not available.

                             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 be used, if appropriate.  The indices
are not available for direct  investment.  The data presented is not meant to be
indicative of the  performance of the Fund,  reflects past  performance and does
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  Composite  Index
includes  500 of the  largest  stocks  (in terms of stock  market  value) in the
United States; prior to March 1957 it consisted of 90 of the largest stocks.

DOW JONES INDUSTRIAL AVERAGE
This is a total return index based on the performance of 30 blue chip stocks.

U.S. SMALL STOCK INDEX
This index is a market value  weighted  index of the ninth and tenth  deciles of
the New York Stock  Exchange  (NYSE),  plus stocks listed on the American  Stock
Exchange (AMEX) and over-the-counter  (OTC) 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 Index 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.

LONG-TERM U.S. GOVERNMENT BONDS
The  total  returns  on  long-term  government  bonds  from  1977  to  1991  are
constructed  with data from The Wall Street Journal.  Over  1926-1976,  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.  Total returns for 1977-1991 are calculated as the change in the
flat price or and-interest price.

INTERMEDIATE-TERM U.S. GOVERNMENT BONDS
Total  returns  of the  intermediate-term  government  bonds for  1977-1991  are
calculated from The Wall Street Journal prices,  using the change in flat price.
Returns from 1934-1986 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 5 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  1934-1942,  almost all bonds
with maturities near 5 years were partially or full 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 1926-1933, there are few bonds suitable for construction of a series
with a 5-year  maturity.  For this period,  five year bond yield  estimates  are
used.

MSCI
Morgan  Stanley  Capital  International   Indices,   developed  by  the  Capital
International  S.A., are based on share prices of some 1470 companies  listed on
the stock exchanges around the world.

Countries in the MSCI EAFE Portfolio are:
Australia;  Austria;  Belgium;  Denmark;  Finland;  France;  Germany; Hong Kong;
Italy;  Japan;  Netherlands;  N.  Zealand;  Norway;  Singapore/Malaysia;  Spain;
Sweden; Switzerland; United Kingdom.

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

LONG-TERM U.S. CORPORATE BONDS
For  1969-1991,  corporate  bond total  returns are  represented  by the Salomon
Brothers Long-Term  High-Grade  Corporate Bond Index. Since 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. 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.

Over  1926-1968  the total  returns  were  calculated  by  summing  the  capital
appreciation returns and the income returns. For the period 1946-1968,  Ibbotson
and Sinquefield  backdated the Salomon Brothers' index,  using Salomon Brothers'
monthly  yield  data with a  methodology  similar  to that used by  Salomon  for
1969-1991. 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 1926-1945, the Standard and Poor's monthly High-Grade Corporate Composite
yield data were used,  assuming a 4 percent 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 Randolph W. Westerfield,  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 for
1977-1991;  the CRSP U.S.  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.

NAREIT-EQUITY INDEX
All of the  data is  based  upon the last  closing  price of the  month  for all
tax-qualified  REITs  listed  on the  NYSE,  AMSE  and the  NASDAQ.  The data is
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 weighing 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 2000 SMALL STOCK INDEX
Index of the 2,000 smallest  stocks in the Russell 3000 Index (TM); the smallest
company has a market capitalization of approximately $13 million.
The Russell  3000 is comprised of the 3,000  largest US companies as determined
by market capitalization representing approximately 98% of the US equity market.
The largest company in the index has a market capitalization of $67 billion. The
Russell Indexes (TM) are reconstituted  annually as of June 1st, based on May 31
market capitalization rankings.

WILSHIRE REAL ESTATE SECURITIES INDEX
The Wilshire Real Estate  Securities  Index is a market  capitalization-weighted
index which measures the performance of more than 85 securities.

The index  contains  performance  data on five  major  categories  of  property;
office, retail, industrial, apartment and miscellaneous. Additionally, the Index
has real estate portfolio encumbered by 16% third party mortgages. The companies
in the WRESEC are 79% equity  and hybrid  REIT's and 21% real  estate  operating
companies. The capitalization is 47% NYSE, 33% AMEX and 20% OTC."

STANDARD & POOR'S MIDCAP 400 INDEX
The Standard and Poor's MidCap 400 Index is a  market-value-weighted  index. The
performance  data for the MidCap 400 Index were  calculated by taking the stocks
presently in the MidCap 400 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  MidCap  400  Index  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.

                               INDEX DESCRIPTIONS


The S&P MidCap 400 Index and the S&P 500 together represent approximately 85% of
the total market capitalization of stocks traded in the United States.

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 1963-1987 and The Wall Street Journal for the years 1988-1994.

                                      -----


         Pioneer Bond Fund, a  Massachusetts  business  trust with its principal
place of business at 60 State Street,  Boston,  Massachusetts 02109 ("Customer")
and Pioneering Services Corporation, a Massachusetts corporation ("PSC"), hereby
agree as follows:

         1. SERVICES TO BE PROVIDED BY PSC.  During the term of this  Agreement,
PSC will provide to each series of shares of beneficial  interest (the "Series")
of Customer, which may be established,  from time to time (the "Account"),  with
the services described in Exhibits A, B, C, and D (collectively, the "Exhibits")
that are attached hereto and incorporated herein by reference.  It is understood
that PSC may subcontract any of such services to one or more firms designated by
PSC,  provided  that PSC (i) shall be solely  responsible  for all  compensation
payable  to any such firm and (ii) shall be liable to  Customer  for the acts or
omissions of any such firm to the same extent as PSC would be liable to Customer
with respect to any such act or omission hereunder.

         2. EFFECTIVE DATE.  This Agreement  shall become  effective on the date
hereof  (the  "Effective  Date")  and  shall  continue  in  effect  until  it is
terminated in accordance with Section 11 below.

         3. DELIVERY, VERIFICATION AND RECEIPT FOR DATA AND ASSETS. Prior to the
Effective Date, Customer agrees to deliver to PSC all such  documentation,  data
and  materials  as PSC may  reasonably  prescribe  to enable it to  perform  the
services contemplated by this Agreement. If PSC so requests,  Customer agrees to
confirm the accuracy of any starting  records of Customer's  assets and accounts
produced from PSC's computer or held in other  recording  systems.  In the event
Customer  does not,  prior to the Effective  Date,  comply fully with any of the
foregoing  provisions  of this  Section  3, the date for  commencement  of PSC's
services  hereunder  may be  postponed  by PSC until such  compliance  has taken
place.

         Customer  shall,  from time to time,  while this Agreement is in effect
deliver all such  materials  and data as may be necessary or desirable to enable
PSC to perform its  services  hereunder,  including  without  limitation,  those
described in Section 12 hereof.

         4.  REPORTS  AND  MAINTENANCE  OF RECORDS BY PSC.  PSC will  furnish to
Customer and to properly authorized Auditors, examiners, distributors,  dealers,
underwriters, salesmen, insurance companies, investors, and others designated by
Customer in writing,  such books,  any and all records and reports at such


<PAGE>

times as are  prescribed  for each  service  in the  Exhibits  attached  hereto.
Customer agrees to examine or to ask any other  authorized  recipient to examine
each such report or copy  promptly  and will report or cause to be reported  any
errors or  discrepancies  therein of which Customer then has any knowledge.  PSC
may at its option at any time, and shall forthwith upon Customer's demand,  turn
over to  Customer  and cease to retain in PSC's  files,  any and all records and
documents  created and maintained by PSC pursuant to this Agreement which are no
longer needed by PSC in the performance of its services or for its protection.

         If not so turned over to Customer,  such  documents and reports will be
retained  by PSC for six years from the year of the  creation,  during the first
two of which  the same will be in  readily  accessible  form.  At the end of six
years, such records and documents, will be turned over to Customer by PSC unless
Customer authorizes their destruction.

         5. PSC'S DUTY OF CARE.  PSC shall at all time use  reasonable  care and
act in good  faith in  performing  its  duties  hereunder.  PSC  shall  incur no
liability to Customer in connection with its  performance of services  hereunder
except to the extent that it does not comply with the foregoing standards.

         PSC  shall at all  times  adhere  to  various  procedures  and  systems
consistent  with  industry  standards in order to safeguard  Customer's  checks,
records and other data from loss or damage  attributable  to fire or theft.  PSC
shall maintain insurance adequate to protect against the costs of reconstructing
checks,  records  and other  data in the  event of such  loss and  shall  notify
Customer in the event of a material  adverse change in such insurance  coverage.
In the event of damage or loss occurring to Customer's records or data such that
PSC is unable  to meet the  terms of this  Agreement,  PSC  shall  transfer  all
records and data to a transfer  agent of  Customer's  choosing  upon  Customer's
written authorization to do so.

         Without  limiting the  generality  of the  foregoing,  PSC shall not be
liable or responsible for delays or errors  occurring by reason of circumstances
beyond its  control  including  acts of civil,  military  or banking  authority,
national  emergencies,  labor  difficulties,  fire, flood or other catastrophes,
acts of God, insurrection, war, riots, failure of transportation,  communication
or power supply.

         6.  CONFIDENTIALITY.   PSC  will  keep  confidential  all  records  and

         7. CUSTOMER  INSPECTION.  Upon reasonable  notice, in writing signed by
Customer,  PSC shall make available,  during regular business hours, all records
and other data created and maintained  pursuant to this Agreement for reasonable
audit and  inspection by Customer or  Customer's  agents,  including  reasonable
visitation by Customer or Customer's agent, including inspecting PSC's operation
facilities.  PSC shall not be liable for injury to or responsible in any way for
the safety of any individual  visiting PSC's  facilities  under the authority of
this  section.   Customer  will  keep   confidential  and  will  cause  to  keep
confidential all confidential information obtained by its employees or agents or
any other individual representing Customer while on PSC's premises. Confidential
information shall include (1) any information of whatever nature regarding PSC's
operations, security procedures, and data processing capabilities, (2) financial
information  regarding  PSC,  its  affiliates,  or  subsidiaries,  and  (3)  any
information of whatever kind or  description  regarding any customer of PSC, its
affiliates or subsidiaries.

         8. RELIANCE BY PSC ON INSTRUCTIONS AND ADVICE;  INDEMNITY. PSC shall be
entitled  to seek  advice of  Customer's  legal  counsel  with  respect to PSC's
responsibilities  and  duties  hereunder  and  shall in no event  be  liable  to
Customer for any action taken pursuant to such advice, except to the extent that
Customer's legal counsel determines in its sole discretion that the rendering of
advice to PSC would result in a conflict of interest.

         Whenever PSC is authorized to take action hereunder  pursuant to proper
instructions from Customer,  PSC shall be entitled to rely upon any certificate,
letter or other  instrument or telephone call  reasonably  believed by PSC to be
genuine  and to have  been  properly  made or  signed  by an  officer  or  other
authorized  agent of  Customer,  and shall be entitled to receive as  conclusive
proof of any  fact or  matter  required  to be  ascertained  by it  hereunder  a
certificate  signed by an officer of Customer or any other person  authorized by
Customer's Board of Trustees.

         Subject to the  provisions  of Section 13 of this  Agreement,  Customer
agrees to indemnify and hold PSC, its  employees,  agents and nominees  harmless
from any and all claims,  demands,  actions  and suits,  whether  groundless  or
otherwise,  and from and against  any and all  judgments,  liabilities,  losses,
damages,  costs,  charges,  counsel fees and other  expenses of every

non-action  upon  information,  instructions or requests given or made to PSC by
Customer with respect to the Account.

         Notwithstanding the above,  whenever Customer may be asked to indemnify
or hold PSC harmless,  Customer shall be advised of all pertinent  facts arising
from the situation in question.  Additionally,  PSC will use reasonable  care to
identify and notify Customer  promptly  concerning any situation which presents,
actually or potentially, a claim for indemnification against Customer.  Customer
shall have the option to defend PSC  against any claim for which PSC is entitled
to  indemnification  from  Customer  under  the terms  hereof,  and in the event
Customer so elects, it will notify PSC and, thereupon,  Customer shall take over
complete  defense of the claim and PSC shall  sustain no further  legal or other
expenses  in such a  situation  for  which  indemnification  shall be  sought or
entitled.  PSC may in no event  confess any claim or make any  compromise in any
case in which  Customer  will be asked to indemnify  PSC except with  Customer's
prior written consent.

         9.  MAINTENANCE  OF DEPOSIT  ACCOUNTS.  PSC shall maintain on behalf of
Customer such deposit  accounts as are necessary or desirable  from time to time

perform any one or more of the services  contemplated  by this  Agreement or any
exhibit hereto,  the provisions of this Agreement,  including without limitation

continue in full force and effect.

thereunder, the "1940 Act");

(the "Class C Shares") of the Trust in accordance with Rule 12b-1 promulgated by
the Securities and Exchange  Commission  under the 1940 Act ("Rule 12b-1"),  and
desires to adopt this Class C Shares distribution plan (the "Class C Plan") as a
plan of distribution pursuant to such Rule;

         WHEREAS,  the Trust  desires that Pioneer  Funds  Distributor,  Inc., a
Massachusetts corporation ("PFD"), provide certain distribution services for the
Trust's Class C Shares in connection with the Class C Plan;

         WHEREAS,  the Trust has entered into an  underwriting  agreement  (in a
form  approved by the Trust's  Board of Trustees in a manner  specified  in such
Rule 12b-1) with PFD, whereby PFD provides  facilities and personnel and renders
services to the Trust in connection with the offering and  distribution of Class

         WHEREAS, the Board of Trustees of the Trust, in considering whether the

                  limitation:  compensation to and expenses (including allocable
                  overhead,  travel  and  telephone  expenses)  of (i)  Dealers,
                  brokers  and other  dealers  who are  members of the  National
                  Association  of  Securities  Dealers,  Inc.  ("NASD") or their
                  officers,  sales  representatives and employees,  (ii) PFD and
                  any of its  affiliates and any of their  respective  officers,
                  sales  representatives  and  employees,  (iii) banks and their
                  officers,  sales representatives and employees,  who engage in
                  or  support  distribution  of  the  Trust's  Class  C  Shares;
                  printing of reports and  prospectuses  for other than existing
                  shareholders;  and  preparation,  printing and distribution of

<PAGE>

                           (d) The amount of  compensation  paid  during any one
                  year  for  personal  and  account  maintenance   services  and
                  expenses shall be .25% of the Trust's average daily net assets
                  attributable  to Class C  Shares  for such  year.  As  partial
                  consideration for personal services and/or account maintenance
                  services  provided by PFD to the Class C Shares,  PFD shall be
                  entitled  to be paid any fees  payable  under this  clause (d)
                  with  respect  to Class C shares for which no dealer of record
                  exists,  where less than all  consideration has been paid to a
                  dealer  of record or where  qualification  standards  have not
                  been met.

                           (e)  Personal  and account  maintenance  services for
                  which PFD or any of its  affiliates,  banks or Dealers  may be
                  compensated pursuant to this Plan include, without limitation:
                  payments  made  to  or  on  account  of  PFD  or  any  of  its
                  affiliates,  banks,  other brokers and dealers who are members
                  of the NASD,  or their  officers,  sales  representatives  and
                  employees, who respond to inquiries of, and furnish assistance
                  to,  shareholders  regarding their ownership of Class C Shares
                  or  their  accounts  or  who  provide  similar   services  not
                  otherwise provided by or on behalf of the Trust.

                           (f) PFD may impose certain  deferred sales charges in
                  connection  with the repurchase of Class C Shares by the Trust
                  and PFD may retain (or receive  from the Trust as the case may
                  be) all such deferred sales charges.

                           (g) Appropriate adjustments to payments made pursuant
                  to  clauses  (b)  and (d) of this  paragraph  1 shall  be made
                  whenever  necessary  to ensure  that no payment is made by the
                  Trust in excess of the applicable maximum cap imposed on asset
                  based,  front-end and deferred sales charges by subsection (d)
                  of Section 26 of Article III of the Rules of Fair  Practice of
                  the NASD.

         II. The Trust  understands that agreements  between PFD and Dealers may
provide  for payment of fees to Dealers in  connection  with the sale of Class C
Shares and the provision of services to  shareholders  of the Trust.  Nothing in
this Class C Plan shall be construed as requiring  the Trust to make any payment
to any  Dealer  or to have any  obligations  to any  Dealer in  connection  with
services as a dealer of the Class C Shares.  PFD shall agree and undertake  that
any  agreement  entered into between PFD and any Dealer shall  provide that such
Dealer shall look solely to PFD for compensation for its services thereunder and
that in no event shall such Dealer seek any payment from the Trust.
<PAGE>

         III.  Nothing herein  contained shall be deemed to require the Trust to
take any action  contrary to its  Declaration of Trust,  as it may be amended or
restated from time to time, or By-Laws or any applicable statutory or regulatory
requirement  to which it is  subject  or by which it is bound,  or to relieve or
deprive the Trust's Board of Trustees of the  responsibility  for and control of
the conduct of the affairs of the Trust.

         IV. This Class C Plan shall  become  effective  upon  approval by (i) a
"majority of the outstanding  voting securities" of Class C of the Trust, (ii) a
vote of the Board of  Trustees,  and (iii) a vote of a majority of the  Trustees
who are not "interested persons" of the Trust and who have no direct or indirect
financial  interest in the  operation  of the Class C Plan or in any  agreements
related to the Class C Plan (the "Qualified Trustees"),  such votes with respect
to (ii) and (iii) above to be cast in person at a meeting called for the purpose
of voting on this Class C Plan.

         V. This Class C Plan will remain in effect indefinitely,  provided that
such continuance is "specifically  approved at least annually" by a vote of both
a  majority  of the  Trustees  of the  Trust  and a  majority  of the  Qualified
Trustees.  If such  annual  approval  is not  obtained,  this Class C Plan shall
expire on January 31, 1997.

         VI.  This  Class C Plan  may be  amended  at any  time by the  Board of
Trustees,  provided  that  this  Class C Plan  may not be  amended  to  increase
materially the limitations on the annual  percentage of average net assets which
may be expended  hereunder without the approval of holders of a "majority of the
outstanding voting securities" of Class C of the Trust and may not be materially
amended in any case  without a vote of a majority of both the  Trustees  and the
Qualified Trustees. This Class C Plan may be terminated at any time by a vote of
a majority of the Qualified  Trustees or by a vote of the holders of a "majority
of the outstanding voting securities" of Class C of the Trust.

         VII. The Trust and PFD shall  provide to the Trust's Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the amounts  expended  under this Class C Plan and the  purposes  for which such
expenditures were made.

         VIII.  While  this  Class  C  Plan  is in  effect,  the  selection  and
nomination  of Qualified  Trustees  shall be committed to the  discretion of the
Trustees who are not "interested persons" of the Trust.
<PAGE>

         IX.  For the  purposes  of this Class C Plan,  the terms  "assignment,"
"interested  persons,"  "majority  of the  outstanding  voting  securities"  and
"specifically approved at least annually" are used as defined in the 1940 Act.

         X. The  Trust  shall  preserve  copies of this  Class C Plan,  and each
agreement  related  hereto and each  report  referred  to in  Paragraph 7 hereof
(collectively,  the "Records"), for a period of not less than six (6) years from
the end of the fiscal year in which such  Records were made and, for a period of
two (2) years, each of such Records shall be kept in an easily accessible place.

         XI. This Class C Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

         XII.  If any  provision  of  this  Class C Plan  shall  be held or made
invalid by a court decision,  statute,  rule or otherwise,  the remainder of the
Class C Plan shall not be affected thereby.

                                PIONEER BOND FUND

                   Multiple Class Plan Pursuant to Rule 18f-3

                Class A Shares, Class B Shares and Class C Shares

                                January 31, 1996


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

         Article I.  Class A Shares

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

         Article II.  Class B Shares

         Class B Shares  are sold at net  asset  value  per  share  without  the
imposition of an initial sales charge. However, Class B

<PAGE>

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

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

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

         Article III.      Class C Shares

         Class C Shares  are sold at net  asset  value  per  share  without  the
imposition of an initial sales charge.  However,  Class C shares redeemed within
one year of  purchase  will be  subject  to a CDSC as set  forth  in the  Fund's
prospectus. Class C Shares are sold subject to the minimum purchase requirements
set forth in the Fund's  prospectus.  Class C Shares  shall be  entitled  to the
shareholder  services set forth from time to time in the Fund's  prospectus with
respect to Class C Shares.  Class C Shares are subject to fees  calculated  as a
stated  percentage  of the net assets  attributable  to Class C shares under the
Class C Rule 12b-1 Distribution Plan as set forth in such Distribution Plan. The
Class C  Shareholders  of the Fund have exclusive  voting  rights,  if any, with
respect to the Fund's Class C Rule 12b-1 Distribution Plan. Transfer agency fees
are allocated to Class C Shares on a

<PAGE>

per account basis except to the extent,  if any, such an allocation  would cause
the Fund to fail to satisfy  any  requirement  necessary  to obtain or rely on a
private letter ruling from the IRS relating to the issuance of multiple  classes
of shares.  Class C shares  shall bear the costs and  expenses  associated  with
conducting a shareholder meeting for matters relating to Class C shares.

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

         Article IV.       Approval by Board of Trustees

         This Plan shall not take effect until it has been  approved by the vote
of a  majority  (or  whatever  greater  percentage  may,  from time to time,  be
required under Rule 18f-3 under the  Investment  Company Act of 1940, as amended
(the "Act")) of (a) all of the Trustees of the Trust, on behalf of the Fund, and
(b) those of the Trustees who are not "interested persons" of the Trust, as such
term may be from time to time defined under the Act.

         Article V.        Amendments

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