                      OF PIONEER INTERMEDIATE TAX-FREE FUND


                                   PROSPECTUS
                     FOR CLASS A, CLASS B AND CLASS C SHARES
                         OF PIONEER TAX-FREE INCOME FUND

This proxy statement and prospectus contains the information you should know
before voting on the proposed reorganization of your fund into Pioneer Tax-Free
Income Fund. Please read it carefully and retain it for future reference.

HOW THE REORGANIZATION WILL WORK:

          Your fund will transfer all of its assets to Tax-Free Income Fund.
         Tax-Free Income Fund will assume your fund's liabilities.

          Tax-Free Income Fund will issue Class A shares to your fund in an
         amount equal to the value of your fund's Class A shares. These shares
         will be distributed to your fund's Class A shareholders in proportion
         to their holdings on the reorganization date. In this same manner,
         Tax-Free Income Fund will issue Class B and Class C shares to your fund
         that will be distributed to your fund's Class B and Class C
         shareholders in proportion to their respective holdings on the
         reorganization date.

          The reorganization will be tax-free.

          Your fund will be terminated and you will end up as a shareholder of
Tax-Free Income Fund.

AN INVESTMENT IN TAX-FREE INCOME FUND IS NOT A BANK DEPOSIT AND IS NOT INSURED
OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER
GOVERNMENT AGENCY.

NO GOVERNMENT SECURITIES COMMISSION OR AGENCY HAS APPROVED TAX-FREE INCOME
FUND'S SHARES AS AN INVESTMENT OR DETERMINED WHETHER THIS PROSPECTUS IS ACCURATE
OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIME.


<PAGE>


WHY YOUR FUND'S TRUSTEES ARE RECOMMENDING THE REORGANIZATION

The trustees of your fund believe that reorganizing your fund into a larger fund
with similar investment policies would enable the shareholders of your fund to
benefit from increased diversification, the ability to achieve better net prices
on securities trades and economies of scale that could contribute to a lower
expense ratio.
Therefore, the trustees recommend you vote FOR the reorganization.

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

BUYING, SELLING     The procedures for buying, selling and exchanging shares are
AND EXCHANGING:     identical for both funds.  These procedures are described
                    in detail below.
- ------------------- ------------------------------------------------------------


REORGANIZATION

          The reorganization is scheduled to occur as of 5:00 p.m., Eastern
         time, on March 31, 1999, but may occur as of any later date before
         September 30, 1999. Your fund will transfer all of its assets to
         Tax-Free Income Fund. Tax-Free Income Fund will assume your fund's
         liabilities. The net asset values of both funds will be computed as of
         the close of the New York Stock Exchange (normally 4:00 p.m., Eastern
         time) on the reorganization date.

          Tax-Free Income Fund will issue to your fund Class A shares of
         Tax-Free Income Fund in an amount equal to the aggregate net asset
         value of your fund's Class A shares. Your fund will immediately
         distribute these shares to your fund's Class A shareholders in
         proportion to their holdings on the reorganization date. In this same
         manner, Tax-Free Income Fund will issue to your fund Class B and Class
         C shares that will be distributed to your fund's Class B and Class C
         shareholders in proportion to their respective holdings on the
         reorganization date. As a result, Class A shareholders of your fund
         will end up as Class A shareholders of Tax-Free Income Fund, Class B
         shareholders of your fund will end up as Class B shareholders of
         Tax-Free Income Fund, and Class C shareholders of your fund will end up
         as Class C shareholders of Tax-Free Income Fund.

          After the reorganization is over, your fund will be terminated.

          The reorganization will be federally tax-free and will not take place
         unless both funds receive a satisfactory opinion concerning the federal
         income tax consequences of the reorganization from Hale and Dorr LLP,
         counsel to the funds.

OTHER CONSEQUENCES OF THE REORGANIZATION. Each fund pays monthly advisory fees
equal to the following annual percentage of average daily net assets:

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

 FUND ASSET BREAKPOINTS                INTERMEDIATE TAX-FREE    TAX-FREE INCOME
- --------------------------------------------------------------------------------
First $250 million                                                  0.50%
- --------------------------------------         0.50%           -----------------
Over $250 million up to $300 million                                0.48%
- --------------------------------------                         -----------------
Over $300 million                                                   0.45%
- --------------------------------------------------------------------------------

Thus, at all asset levels, the annual advisory fee rate payable by Tax-Free
Income Fund is the same as or lower than the rate paid by your fund. Because of
Tax-Free Income Fund's current asset size, your fund's management fee rate
(without giving effect to fee waivers) is higher than the fee rate payable by
Tax-Free Income Fund. In addition, if your fund's assets were added to Tax-Free
Income Fund as a result of the reorganization, it is likely that the effective
management fee rate would be even lower because Tax-Free Income Fund's assets
have already reached the most favorable breakpoint. Your fund is currently
paying a lower advisory fee because of voluntary fee waivers. These fee waivers
may be discontinued by Pioneer at any time.



<PAGE>


In addition to lower advisory fee rates, Tax-Free Income Fund's Class A expense
ratio of 0.93% for the calendar year ended December 31, 1997, as well as its PRO
FORMA expense ratio of 0.95%, are lower than your fund's gross Class A expense
ratio of 1.18% (1.00% for net expenses with the expense limitation).
Furthermore, Tax-Free Income Fund's other expenses are lower than your fund's
gross other expenses. Both funds pay the same 12b-1 fee rates for each class.

Although Pioneer has voluntarily agreed to limit your fund's expenses, your
fund's total annual operating expenses are still higher than Tax-Free Income
Fund's. In light of your fund's inability to attract significant assets, Pioneer
may not continue to subsidize a portion of your fund's expenses indefinitely. If
Pioneer discontinued this voluntary limitation, your fund's total annual
operating expenses would rise even further above Tax-Free Income Fund's.


                               RISK/RETURN SUMMARY

INVESTMENT OBJECTIVES

INTERMEDIATE TAX-FREE FUND. As high a level of current income exempt from
federal income taxes from a high-quality portfolio of municipal bonds as is
consistent with prudent investment risk.

TAX-FREE INCOME FUND. As high a level of current income exempt from federal
income taxes as possible consistent with the preservation of capital.

INVESTMENT STRATEGIES

INTERMEDIATE TAX-FREE FUND. Intermediate Tax-Free Fund invests at least 80% of
its assets in bonds, notes and other debt instruments issued by or on behalf of
states, territories or possessions of the U.S. and the District of Columbia and
their political subdivisions, agencies or instrumentalities, the interest on
which is exempt from federal income tax ("Municipal Securities"). The municipal
bonds in which the fund invests are rated in the four highest rating categories
by a nationally recognized statistical rating organization or determined by
Pioneer to be of comparable quality. The municipal notes in which the fund may
invest are rated AAA, AA or A by a nationally recognized statistical rating
organization or determined by Pioneer to be of comparable quality. No more than
15% of the fund's assets may be rated BBB. The dollar weighted average maturity
of the fund's portfolio will not exceed 10 years. At least 80% of the fund's
assets have a remaining maturity of 15 years or less.

TAX-FREE INCOME FUND. Tax-Free Income Fund invests in a diversified portfolio of
Municipal Securities rated in the three highest rating categories by Moody's
Investors Service, Inc. or Standard & Poor's Ratings Group. The Municipal
Securities in which the fund invests may be of any maturity and the fund has no
policy with respect to the average maturity of its portfolio. Tax-Free Income
Fund may invest 25% or more of its assets in issuers in one state or securities
the payments on which are derived from gas, electric, telephone, sewer and water
segments of the municipal bond market. The fund may also invest up to 25% of its
assets in industrial development bonds.



<PAGE>


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

PRINCIPAL RISKS OF INVESTING IN THE FUNDS

Each fund is subject to similar risks. Even though each fund seeks current
income, you could lose money on your investment or not make as much as if you
invested elsewhere if:

o    Interest rates increase, causing the value of a fund's portfolio to decline
o    The issuer of a security owned by a fund defaults on its obligation to
     pay principal or interest or has its credit rating downgrade
o    New federal or state legislation adversely affects the tax-exempt status of
     securities held by a fund or the financial ability of municipalities to
     repay these obligations
o    The issuer of a Municipal Security may not be able to make timely payments
     because of a general economic downturn or increased governmental costs
o    Pioneer is incorrect in its expectation of changes in interest rates or the
     credit quality of an issuer

It is possible that some of a fund's income distributions may be, and
distributions of a fund's capital gains will be, subject to federal taxation. A
fund may realize taxable gains on the sale of its securities or other
transactions, and some of a fund's income distributions may be subject to the
federal alternative minimum tax. In addition, distribution of a fund's income
and gains generally will be subject to state taxation.

EACH FUND'S PAST PERFORMANCE

The bar chart and table show how the funds have performed in the past.  Each
fund's performance varies from year to year. A fund's past performance does not
necessarily indicate how it will perform in the future. As a shareholder, you
may experience a loss or gain on your investment.

         fund operating expenses, including these amounts and the adviser's
         voluntary waiver, were 1.00% for Class A, 1.79% for Class B and 1.82%
         for Class C. The advisory fee waiver is voluntary and temporary and may
         be revised or terminated at any time.
(4)      Does not reflect amounts paid to Tax-Free Income Fund in connection
         with certain expense offset arrangements. Tax-Free Income Fund's actual

         for Class B and 0.19% for Class C. Total annual fund operating
         expenses, including these amounts, were 0.91% for Class A, 1.66% for
         Class B and 1.67% for Class C.

PRO FORMA EXPENSE TABLE

The next expense table shows the PRO FORMA expenses of Tax-Free Income Fund
assuming that a reorganization with your fund occurred on January 1, 1997. The
expenses shown in the table are based on fees and expenses incurred by the funds
during the fiscal year ended December 31, 1997. Tax-Free Income Fund's actual
expenses after the reorganization may be greater or less than those shown. The
PRO FORMA expense example shows what you would pay on a $10,000 investment if
the reorganization had occurred on January 1, 1997 using the assumptions
previously stated for the funds individually. The PRO FORMA example is for
comparison purposes only and is not a representation of Tax-Free Income Fund's
actual expenses or returns, either past or future.

OTHER INVESTMENT STRATEGIES

As discussed, each fund invests primarily in Municipal Securities to seek
current income exempt from federal income tax.


<PAGE>


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

TEMPORARY INVESTMENTS

Normally, each fund invests substantially all of its assets to meet its
investment objective. Each fund may invest the remainder of its assets in cash
equivalents or may hold cash. For temporary defensive purposes, each fund may
depart from its principal investment strategies and invest part or all of its
assets in securities with a remaining maturity of less than one year. The funds
intend to adopt a defensive strategy only when Pioneer believes Municipal
Securities have extraordinary risks due to political or economic factors.

SHORT-TERM TRADING

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

DERIVATIVES

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

o         As a hedge against adverse changes in interest rates

o         As a substitute for purchasing or selling securities

o         To increase the fund's return

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

YEAR 2000

<PAGE>

Information technology experts are concerned about computer and other electronic
systems' ability to process date related information on and after January 1,
2000. This scenario, commonly referred to as the "Year 2000 problem," could have
an adverse impact on the funds and the provision of services to their
shareowners. Pioneer is addressing the Year 2000 problem with respect to its
systems and those used by the distributor and transfer agent. During 1999,
Pioneer expects to finish addressing all material Year 2000 issues and to
participate in industry-wide testing. The funds have obtained assurances from
their other service providers that they are taking appropriate Year 2000
measures and Pioneer is monitoring their efforts. Although neither fund expects
the Year 2000 problem to adversely impact it, neither fund can guarantee that
its, or the fund's service providers', efforts will be successful.


                        PROPOSAL TO APPROVE THE AGREEMENT
                           AND PLAN OF REORGANIZATION

DESCRIPTION OF REORGANIZATION

The shareholders of your fund are being asked to approve an Agreement and Plan
of Reorganization, a copy of which is attached as Exhibit A. The Agreement
provides for a reorganization on the following terms:

o        The reorganization is scheduled to occur as of 5:00 p.m., Eastern
         time, on March 31, 1999, but may occur on any later date before
         September 1, 1999. Your fund will transfer all of its assets to
         Tax-Free Income Fund, and Tax-Free Income Fund will assume all of your
         fund's liabilities. This will result in the addition of your fund's
         assets to Tax-Free Income Fund's portfolio. The net asset values of
         both funds will be computed as of the close of the New York Stock
         Exchange (normally 4:00 p.m. Eastern time) on the reorganization date.

o        Tax-Free Income Fund will issue to your fund Class A shares of
         Tax-Free Income Fund in an amount equal to the aggregate net asset
         value of your fund's Class A shares. As part of the liquidation of your
         fund, your fund will immediately distribute these shares to Class A
         shareholders of record of your fund in proportion to their holdings on
         the reorganization date. In this same manner, Tax-Free Income Fund will
         issue to your fund Class B and Class C shares that will be distributed
         to your fund's Class B and Class C shareholders in proportion to their
         respective holdings on the reorganization date. As a result, Class A
         shareholders of your fund will end up as Class A shareholders of
         Tax-Free Income Fund, Class B shareholders of your fund will end up as
         Class B shareholders of Tax-Free Income Fund, and Class C shareholders
         of your fund will end up as Class C shareholders of Tax-Free Income
         Fund.

o        After the reorganization is over, your fund will be terminated.

REASONS FOR THE PROPOSED REORGANIZATION

The board of trustees of your fund believes that the proposed reorganization
will be advantageous to the shareholders of your fund for several reasons. The
board of trustees considered the following matters, among others, in approving
the proposal.

FIRST, that a combined fund offers economies of scale that may lead to better
control over expenses than is possible for your fund. Both funds incur
substantial costs for accounting, legal, transfer agency, insurance, and
custodial and administrative services.

SECOND, that shareholders may be better served by a less restrictive fund. Your
fund has a policy of concentrating its investments in municipal bonds with a
dollar-weighted average maturity not exceeding 10 years. This has limited the
fund's ability to purchase higher yielding bonds with longer maturities and has
limited the fund's ability to gather assets. Tax-Free Income Fund has no stated
policy with respect to maturity, allowing it to invest in a broader range of
securities, and it has a significantly larger asset size than your fund.



<PAGE>


THIRD, that Tax-Free Income Fund has performed better than your fund since its
inception. While past performance cannot predict future results, the trustees
believe that Tax-Free Income Fund is better positioned than your fund to
continue to generate strong returns because of its lower expense ratio and more
flexible investment policies.

FOURTH, that Tax-Free Income Fund's expenses are currently lower than your
fund's expenses. Additionally, if the voluntary limitation on your fund's
expenses were discontinued, your fund's expenses would be substantially higher.
Shareholders of your fund would pay relatively lower fees each month as
shareholders of Tax-Free Income Fund than they would if the reorganization did
not occur, and even less if the voluntary expense limitation on your fund's
expenses were discontinued.

FIFTH, that Tax-Free Income Fund is more widely recognized in the broker
community as Pioneer's primary municipal bond fund. By offering both funds
simultaneously, it has been increasingly difficult to attract assets to your
fund.

SIXTH, that the Tax-Free Income Fund shares received in the reorganization will
provide your fund's shareholders with substantially the same investment
advantages as they currently have, with potential for higher return.

The board of trustees of Tax-Free Income Fund considered that the reorganization
presents an excellent opportunity for Tax-Free Income Fund to acquire investment
assets without the obligation to pay commissions or other transaction costs that
are normally associated with the purchase of securities. The trustees also
believe that your fund's shareholders and Tax-Free Income Fund's shareholders
will benefit from improved diversification as a result of the reorganization.
Because Tax-Free Income Fund is a significantly larger fund than your fund and
because it does not place restrictions on portfolio maturity, the trustees feel
that the addition of your fund's assets will improve the diversification of
Tax-Free Income Fund's overall portfolio. This opportunity provides an economic
benefit to Tax-Free Income Fund and its shareholders. Similarly, the trustees
feel that shareholders of your fund will benefit from the greater
diversification of Tax-Free Income Fund's investment portfolio after the
transaction.

The boards of trustees of both funds also considered that the adviser and the
funds' distributor will also benefit from the reorganization. For example, the
adviser might realize time savings from a consolidated portfolio management
effort and from the need to prepare fewer reports and regulatory filings as well
as prospectus disclosure for one fund instead of two. The trustees believe,
however, that these savings will not amount to a significant economic benefit.
Because of the fee waiver on your fund, Pioneer will also receive a higher
effective fee from managing the assets attributable to your fund if they are a
part of Tax-Free Income Fund than if the reorganization does not take place.

COMPARATIVE FEES AND EXPENSE RATIOS. As discussed above in the Summary, Tax-Free
Income Fund pays the same advisory fee rate as your fund for assets up to $250
million, and pays a rate lower than your fund's fee rate at all other asset
levels. In addition, because your fund's advisory fee does not have breakpoints,
the management fee will remain the same indefinitely.

In addition to lower advisory fee rates, Tax-Free Income Fund's Class A expense
ratio of 0.93% for the calendar year ended December 31, 1997, as well as its PRO
FORMA expense ratio of 0.95%, are lower than your fund's gross Class A expense
ratio of 1.18% (1.00% for net expenses with the expense limitation).
Furthermore, Tax-Free Income Fund's other expenses are lower than your fund's
gross other expenses. Both funds pay the same 12b-1 fee rates for each class.

<PAGE>
The trustees do not believe, given your fund's current size and growth rate,
that your fund will grow to an asset size which would allow your fund to realize
the benefits of economies of scale, including better control over expenses. The
trustees also do not believe that your fund will reach an asset size which will
allow your fund to significantly improve the diversification of its investment
portfolio. In light of your fund's inability to attract significant assets, the
adviser may not continue to subsidize a portion of your fund's expenses
indefinitely. When the adviser discontinues this voluntary limitation, your
fund's expense ratio will rise even further above Tax-Free Income Fund's.

COMPARATIVE PERFORMANCE. The trustees also took into consideration the relative
performance of your fund and Tax-Free Income Fund. As shown in the table in the
Summary, Tax-Free Income Fund has had better performance than your fund over
time.

UNREIMBURSED CLASS A DISTRIBUTION AND SHAREHOLDER SERVICE EXPENSES

The boards of trustees of your fund and Tax-Free Income Fund have determined
that, if the reorganization occurs, unreimbursed distribution and shareholder
service expenses incurred under your fund's Class A 12b-1 Plan will be
reimbursable expenses under Tax-Free Income Fund's Class A Rule 12b-1 Plan.
However, the maximum aggregate amount payable annually under Tax-Free Income
Fund's Class A 12b-1 Plan (0.25% of average daily net assets attributable to
Class A shares) will not increase. The 12b-1 plans for Class B and C are
compensation plans and, consequently, the amounts payable under such plans are
not determined by references to actual distribution expenses incurred.

The following table shows the actual and PRO FORMA unreimbursed distribution and
shareholder service expenses of Class A shares of your fund and Tax-Free Income
Fund. The table shows both the dollar amount of these expenses and the
percentage of each class' average net assets that they represent.
<TABLE>
<S>                                        <C>                         <C>

Actual expenses as of December 31, 1998         $                           $
                                                  %                           %

PRO FORMA combined expenses
as of January 1, 1998                                                       $
                                                                              %
</TABLE>
Thus, if the reorganization had taken place on January 1, 1998, the PRO FORMA
combined unreimbursed expenses of Tax-Free Income Fund's Class A shares would
have been higher than if no reorganization had occurred. Nevertheless, Tax-Free
Income Fund's assumption of your fund's unreimbursed Class A 12b-1 expenses will
have no immediate effect upon the payments made under Tax-Free Income Fund's
Class A 12b-1 Plan. The Class A Plan does not provide for the carryover of
reimbursable expenses beyond 12 months from the time a fund is first invoiced
for an expense. The limited carryover provision in the Class A Plan may result
in an expense invoiced to a 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, a fund has
12 months to reimburse any expense which it incurs prior to such termination or
non-continuance, provided that payments by the fund during such 12-month period
shall not exceed 0.25% of the fund's average daily net assets during such
period.

TAX STATUS OF THE REORGANIZATION

The reorganization will be tax-free for federal income tax purposes and will not
take place unless both funds receive a satisfactory opinion from Hale and Dorr
LLP, counsel to the funds, substantially to the effect that:

<PAGE>


o        The reorganization described above will be a "reorganization" within
         the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
         amended (the "Code"), and each fund will be "a party to a
         reorganization" within the meaning of Section 368(b) of the Code;

o        No gain or loss will be recognized by your fund upon (1) the transfer
         of all of its assets to Tax-Free Income Fund as described above or (2)
         the distribution by your fund of Tax-Free Income Fund shares to your
         fund's shareholders;

o        No gain or loss will be recognized by Tax-Free Income Fund upon the
         receipt of your fund's assets solely in exchange for the issuance of
         Tax-Free Income Fund shares to your fund and the assumption of all of
         your fund's liabilities by Tax-Free Income Fund;

o        The basis of the assets of your fund acquired by Tax-Free Income Fund
         will be the same as the basis of those assets in your fund immediately
         before the transfer;

o        The tax holding period of the assets of your fund in Tax-Free Income
         Fund will include your fund's tax holding period for those assets;

o        The shareholders of your fund will not recognize gain or loss upon the
         exchange of all their shares of your fund solely for Tax-Free Income
         Fund shares as part of the reorganization;

o        The basis of Tax-Free Income Fund shares received by your fund's
         shareholders in the reorganization will be the same as the basis of the
         shares of your fund surrendered in exchange; and

o        The tax holding period of the Tax-Free Income Fund shares received by
         your fund's shareholders will include, for each shareholder, the tax
         holding period of the shares of your fund surrendered in exchange,
         provided that shares of your fund were held as capital assets on the
         date of the exchange.

ADDITIONAL TERMS OF AGREEMENT AND PLAN OF REORGANIZATION

SURRENDER OF SHARE CERTIFICATES. Shareholders of your fund whose shares are
represented by one or more share certificates need not surrender their
certificates. After the reorganization, certificates evidencing ownership of
your fund's shares will evidence ownership of Tax-Free Income Fund shares
received in the reorganization. Shareholders must continue to follow procedures
for surrendering your fund's share certificates (or delivering the appropriate
affidavit) in order to redeem shares of Tax-Free Income Fund after the
reorganization. Tax-Free Income Fund will not issue share certificates in the
reorganization.

CONDITIONS TO CLOSING THE REORGANIZATION. The obligation of your fund to
consummate the reorganization is subject to the satisfaction of certain
conditions, including the performance by Tax-Free Income Fund of all its
obligations under the Agreement and the receipt of all consents, orders and
permits necessary to consummate the reorganization (see Agreement, sections 6
and 8).

The obligation of Tax-Free Income Fund to consummate the reorganization is
subject to the satisfaction of certain conditions, including your fund's
performance of all of its obligations under the Agreement, the receipt of
certain documents and financial statements from your fund and the receipt of all
consents, orders and permits necessary to consummate the reorganization (see
Agreement, sections 7 and 8).

<PAGE>

The obligations of both funds are subject to the approval of the Agreement by
the necessary vote of the outstanding shares of your fund, in accordance with
the provisions of your fund's declaration of trust and by-laws. The funds'
obligations are also subject to the receipt of a favorable opinion of Hale and
Dorr LLP as to the federal income tax consequences of the reorganization (see
Agreement, paragraph 8.1).

TERMINATION OF AGREEMENT. The board of trustees of either your fund or Tax-Free
Income Fund may terminate the Agreement (even if the shareholders of your fund
have already approved it) at any time before the reorganization date, if that
board believes that proceeding with the reorganization would no longer be
advisable.

EXPENSES OF THE REORGANIZATION. Tax-Free Income Fund and your fund will each be
responsible for its own expenses incurred in connection with entering into and
carrying out the provisions of the Agreement, whether or not the reorganization
occurs. These expenses are estimated to be approximately $_______ for your fund
and $_______ for Tax-Free Income Fund.

                                 CAPITALIZATION

The following table sets forth the capitalization of each fund as of January 1,
1999, and the PRO FORMA combined capitalization of both funds as if the
reorganization had occurred on such date. The table reflects PRO FORMA exchange
ratios of approximately ____ Class A Tax-Free Income Fund shares being issued
for each Class A share of your fund, approximately ___ Class B Tax-Free Income
Fund shares being issued for each Class B share of your fund and approximately
___ Class C Tax-Free Income Fund shares being issued for each Class C share of
your fund. If the reorganization is consummated, the actual exchange ratios on
the reorganization date may vary from the exchange ratios indicated due to
changes in the market value of the portfolio securities of both Tax-Free Income
Fund and your fund between January 1, 1999 and the reorganization date, changes
in the amount of undistributed net investment income and net realized capital
gains of Tax-Free Income Fund and your fund during that period resulting from
income and distributions, and changes in the accrued liabilities of Tax-Free
Income Fund and your fund during the same period.

       COMPARISON OF BUSINESS TRUSTS UNDER DELAWARE AND MASSACHUSETTS LAW

Your fund is organized as a Massachusetts business trust. Tax-Free Income Fund
is organized as a Delaware business trust. The following is a comparison of the
laws of Massachusetts and Delaware applicable to business trusts.

LIMITATION OF SHAREHOLDERS' AND FUNDS' LIABILITY. Delaware law provides that the
shareholders of a Delaware business trust shall not be subject to liability for
the debts or obligations of the trust. Under Massachusetts law, shareholders of
a Massachusetts business trust (such as your fund) may, under certain
circumstances, be liable for the debts and obligations of that trust. Although
the risk of liability of shareholders of a Massachusetts business trust who do
not participate in the management of the trust may be remote, your board of
trustees has determined that Delaware law affords greater protection against
potential shareholder liability. Similarly, Delaware law provides that, to the
extent that a Delaware business trust issues multiple series of shares, each
series shall not be liable for the debts or obligations of any other series,
another potential, although remote, risk in the case of multiple series of a
Massachusetts business trust. While your board of trustees believes that a
Massachusetts business trust will only be liable for its own obligations, there
is no direct statutory or judicial support for that position.

LIMITATION OF TRUSTEE LIABILITY. Delaware law provides that, except to the
extent otherwise provided in a trust's declaration of trust or by-laws, trustees
will not be personally liable to any person (other than the business trust or a
shareholder thereof) for any act, omission or obligation of the business trust
or any trustee thereof. Delaware law also provides that a trustee's actions
under a Delaware business trust's declaration of trust or by-laws will not
subject the trustee to liability to the business trust or its shareholders if
the trustee takes such action in good faith reliance on the provisions of the
business trust's declaration of trust or by-laws. The declaration of trust of a
Massachusetts business trust may limit the liability of a trustee who is not
also an officer of the trust for breach of fiduciary duty except for, among
other things, any act or omission not in good faith which involves intentional
misconduct or a knowing violation of law or any transaction from which such
trustee derives an improper direct or indirect financial benefit. Your board of
trustees believes that such limitations on liability under Delaware law are
consistent with those applicable to directors of a corporation under Delaware
law and will be beneficial in attracting and retaining in future qualified
persons to act as trustees.

SHAREHOLDER VOTING. Delaware law provides that a Delaware business trust's
declaration of trust or by-laws may set forth provisions related to voting in
any manner. This provision appears to permit trustee and shareholder voting
through computer or electronic media. For an investment company with a
significant number of institutional shareholders, all with access to computer or
electronic networks, the use of such voting methods could significantly reduce
the costs of shareholder voting. However, the advantage of such methods may not
be realizable unless the SEC modifies its proxy rules. Also, as required by the
Investment Company Act of 1940 (the "1940 Act"), votes on certain matters by
trustees would still need to be taken at actual in-person meetings.

<PAGE>

DECLARATIONS OF TRUST. Although neither a Delaware business trust nor a
Massachusetts business trust is required to hold annual shareholder meetings,
Delaware law affords to the trustees the ability to adapt the Delaware business
trust to future contingencies without the necessity of holding a special
shareholder meeting. The trustees of a Delaware business trust may have the
power to amend the business trust's governing instrument to create a class or
series of shares of beneficial interest that was not previously outstanding; to
dissolve the business trust; to incorporate the Delaware business trust; to
merge or consolidate with another entity; to sell, lease, exchange, transfer,
pledge or otherwise dispose of all or any part of the business trust's assets;
to cause any series to become a separate trust; and to change the Delaware
business trust's domicile -- all without shareholder vote. Any exercise of
authority by the trustees will be subject to applicable state and federal law.
The flexibility of Delaware business trusts should help to assure that Delaware
business trust always operates under the most advantageous form of organization
and is intended to reduce the expense and frequency of future shareholder
meetings for non-investment-related operational issues.

                      BOARDS' EVALUATION AND RECOMMENDATION

For the reasons described above, the board of trustees of your fund, including
the trustees who are not "interested persons" of your fund or the adviser (the
independent trustees), approved the reorganization. In particular, the trustees
determined that the reorganization was in the best interests of your fund and
that the interests of your fund's shareholders would not be diluted as a result
of the reorganization. Similarly, the board of trustees of Tax-Free Income Fund,
including the independent trustees, approved the reorganization. They also
determined that the reorganization was in the best interests of Tax-Free Income
Fund and that the interests of Tax-Free Income Fund's shareholders would not be
diluted as a result of the reorganization.
- --------------------------------------------------------------------------------
THE TRUSTEES OF YOUR FUND RECOMMEND THAT YOU VOTE FOR THE PROPOSAL TO APPROVE
THE AGREEMENT AND PLAN OF REORGANIZATION.
- --------------------------------------------------------------------------------
VOTING RIGHTS AND REQUIRED VOTE

Each share of your fund is entitled to one vote. Approval of the above proposal
requires the affirmative vote of a majority of the shares of your fund
outstanding and entitled to vote. For this purpose, a majority of the
outstanding shares of your fund means the vote of the lesser of:

(1) 67% or more of the shares present at the meeting, if the holders of more
than 50% of the shares of the fund are present or represented by proxy, or

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

Shares of your fund represented in person or by proxy, including shares which
abstain or do not vote with respect to the proposal, will be counted for
purposes of determining whether there is a quorum at the meeting. Accordingly,
an abstention from voting has the same effect as a vote AGAINST the proposal.

However, if a broker or nominee holding shares in "street name" indicates on the
proxy card that it does not have discretionary authority to vote on the
proposal, those shares will NOT be considered present and entitled to vote on
the proposal. Thus, a "broker non-vote" has NO EFFECT on the voting in
determining whether the proposal has been adopted in accordance with clause (1)
above, if more than 50% of the outstanding shares (excluding the "broker
non-votes") are present or represented. However, for purposes of determining
whether the proposal has been adopted in accordance with clause (2) above, a
"broker non-vote" has the same effect as a vote AGAINST the proposal because
shares represented by a "broker non-vote" are considered to be outstanding
shares.

If the required approval of shareholders is not obtained, your fund will
continue to engage in business as a separate mutual fund and the board of
trustees will consider what further action may be appropriate.

                     ADDITIONAL INFORMATION ABOUT THE FUNDS

NET ASSET VALUE

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

Each fund generally values its portfolio securities based on market prices or
quotations. When market prices are not available or are considered by Pioneer to
be unreliable, the fund may use an asset's fair value. Fair value is determined
in accordance with procedures approved by the fund's trustees.

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

CHOOSING A CLASS OF SHARES

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

Factors you should consider include:

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

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

DISTRIBUTION PLANS

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

SALES CHARGES: CLASS A SHARES

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

INVESTMENTS OF $1 MILLION OR MORE

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

REDUCED SALES CHARGES

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

SALES CHARGES: CLASS B SHARES

You buy Class B shares at net asset value per share without paying an initial
sales charge. However, you will pay a CDSC to the distributor if you sell your
Class B shares within six years of purchase for Tax-Free Income Fund and four
years for Intermediate Tax-Free Fund. The CDSC decreases as the number of years
since your purchase increases.

</TABLE>
CONVERSION TO CLASS A SHARES

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

Your Class B shares will convert to Class A shares at the beginning of the
calendar month (calendar quarter for shares purchased before October 1, 1998)
that is eight years, in the case of Tax-Free Income Fund, or six years, in the
case of Intermediate Tax-Free Fund, after the date of purchase, except that:

          Shares bought by reinvesting dividends and capital gains will convert
         to Class A shares at the same time as shares on which the dividend or
         distribution was paid

          Shares purchased by exchanging shares from another fund will convert
         on the date that the shares originally acquired would have converted
         into Class A shares



<PAGE>


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

PAYING THE CONTINGENT DEFERRED SALES CHARGE

Several rules apply for Class B shares so that you pay the lowest possible CDSC.

o        The CDSC is calculated on the current market value, or the original
         cost, of the shares you are selling, whichever is less

o        You do not pay a CDSC on reinvested dividends or distributions

o        In determining the number of years since your purchase, all purchases
         are considered to have been made on the first day of that month
         (quarter for shares purchased before October 1, 1998)

o        If you sell only some of your shares, the transfer agent will first
         sell your shares that are not subject to any CDSC and then the shares
         that you have owned the longest

o        You may qualify for a waiver of the CDSC normally charged

SALES CHARGES: CLASS C SHARES

You buy Class C shares at net asset value per share without paying an initial
sales charge. However, if you sell your Class C shares within one year of
purchase, you will pay to the distributor a contingent deferred sales charge of
1% of the current market value, or the original cost, of the shares you are
selling, whichever is less.

PAYING THE CONTINGENT DEFERRED SALES CHARGE

Several rules apply for Class C shares so that you pay the lowest possible CDSC.

o        The CDSC is calculated on the current market value, or the original
         cost, of the shares you are selling, whichever is less

o        You do not pay a CDSC on reinvested dividends or distributions

o        In determining the number of years since your purchase, all purchases
         are considered to have been made on the first day of that month
         (quarter for shares purchased before October 1, 1998)

o        If you sell only some of your shares, the transfer agent will first
         sell your shares that are not subject to any CDSC and then the shares
         that you bought most recently.

o        You may qualify for a waiver of the CDSC normally charged

OPENING YOUR ACCOUNT

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

<PAGE>
ACCOUNT OPTIONS

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

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

PIONEERING SERVICES CORPORATION
P.O. Box 9014
Boston, Massachusetts 02205-9014
Telephone 1-800-225-6292

TELEPHONE TRANSACTION PRIVILEGES

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

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

GENERAL RULES ON BUYING, EXCHANGING AND SELLING YOUR FUND SHARES

SHARE PRICE

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

BUYING

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

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

MINIMUM INVESTMENT AMOUNTS



<PAGE>


Your initial investment must be at least $1,000. Additional investments must be
at least $100 for Class A shares and $500 for Class B or Class C shares. You may
qualify for lower initial or subsequent investment minimums if you are opening a
retirement plan account, establishing an automatic investment plan or placing
your trade through your investment firm.

EXCHANGING

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

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

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

SELLING

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

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

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

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

GOOD ORDER MEANS THAT:

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

                   When you request a telephone purchase,

                   your telephone purchase instruction and
                   good funds. It usually takes three business
                   days for the transfer agent to receive
                   notification from your bank that good funds
                   are available in the amount of your investment.

</TABLE>
DIVIDENDS AND CAPITAL GAINS

The fund declares a dividend from any net investment income each business day.
You begin earning dividends on the first business day following receipt of
payment for shares; your shares continue to earn dividends up to and including
the date you redeem them. Dividends are normally paid on the last business day
of the month or shortly thereafter. The fund distributes net short-term and net
long-term capital gains, if any, in November. The fund may also pay dividends
and distributions at other times if necessary for the fund to avoid federal
income or excise tax. If you invest in the fund close to the time that the fund
makes a capital gains distribution, generally you will pay a higher price per
share and you will pay taxes on the amount of the capital gains distribution
whether you reinvest the distribution or receive it as cash.

Sales and exchanges may be taxable transactions to shareholders.

TAXES



<PAGE>


For federal income tax purposes, your distributions from the fund's net
long-term capital gains (capital gain dividends) are considered long-term
capital gains. Dividends the fund pays from its tax-exempt interest income will
be designated as exempt-interest dividends and will be treated as tax-exempt
interest for federal income tax purposes, although they may increase a
shareholder's liability for alternative minimum tax in certain circumstances.
Dividends (other than capital gain dividends and exempt-interest dividends) and
short-term capital gain distributions are taxable as ordinary income. Dividends
and distributions are taxable, whether you take payment in cash or reinvest them
to buy additional fund shares. You may also have tax consequences (generally, a
capital gain or loss) when you sell or exchange fund shares. Each year the fund
will mail to you information about your dividends and distributions for, and the
shares you sold in, the previous calendar year.

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

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

                                         INFORMATION CONCERNING THE MEETING

SOLICITATION OF PROXIES

In addition to the mailing of these proxy materials, proxies may be solicited by
telephone, by fax or in person by the trustees, officers and employees of your
fund; by personnel of Pioneer and the fund's transfer agent, Pioneering Services
Corporation; or by representatives or compensated agents, including
broker-dealer firms. [____________, a third-party solicitation firm, has agreed
to provide proxy solicitation services to your fund at a cost of approximately
$_______.]

REVOKING PROXIES

A fund shareholder signing and returning a proxy has the power to revoke it at
any time before it is exercised:

o   By filing a written notice of revocation with Pioneering Services
    Corporation, 60 State Street, Boston, Massachusetts 02109, or

o   By returning a duly executed proxy with a later date before the time of th
    meeting, or

o   If a shareholder has executed a proxy but is present at the meeting and
    wishes to vote in person, by notifying the secretary of your fund (without
    complying with any formalities) at any time before it is voted

Being present at the meeting alone does NOT revoke a previously executed and
returned proxy.

OUTSTANDING SHARES AND QUORUM

As of January 29, 1999, _______ Class A shares, __________ Class B shares and
__________ Class C shares of beneficial interest of your fund were outstanding.
Only shareholders of record on February 1, 1999 (the record date) are entitled
to notice of and to vote at the meeting. A majority of the outstanding shares of
your fund that are entitled to vote will be considered a quorum for the
transaction of business.

OTHER BUSINESS

Your fund's board of trustees knows of no business to be presented for
consideration at the meeting other than the proposal. If other business is
properly brought before the meeting, proxies will be voted according to the best
judgment of the persons named as proxies.

ADJOURNMENTS



<PAGE>


If a quorum is not present in person or by proxy at the time any session of the
meeting is called to order, the persons named as proxies may vote those proxies
that have been received to adjourn the meeting to a later date. If a quorum is
present but there are not sufficient votes in favor of the proposal, the persons
named as proxies may propose one or more adjournments of the meeting to permit
further solicitation of proxies concerning the proposal. Any adjournment will
require the affirmative vote of a majority of your fund's shares at the session
of the meeting to be adjourned. If an adjournment of the meeting is proposed
because there are not sufficient votes in favor of the proposal, the persons
named as proxies will vote those proxies favoring the proposal in favor of
adjournment, and will vote those proxies against the reorganization against
adjournment.

TELEPHONE VOTING

In addition to soliciting proxies by mail, by fax or in person, your fund may
also arrange to have votes recorded by telephone by officers and employees of
your fund or by personnel of the adviser or transfer agent. The telephone voting
procedure is designed to verify a shareholder's identity, to allow a shareholder
to authorize the voting of shares in accordance with the shareholder's
instructions and to confirm that the voting instructions have been properly
recorded. If these procedures were subject to a successful legal challenge,
these telephone votes would not be counted at the meeting. Your fund has not
obtained an opinion of counsel about telephone voting, but is currently not
aware of any challenge.

o A shareholder will be called on a recorded line at the telephone number in
  the fund's account records and will be asked to provide the shareholder's
  social security number or other identifying information

o The shareholder will then be given an opportunity to authorize proxies to
  vote his or her shares at the meeting in accordance with the shareholder's
  instructions

o To ensure that the shareholder's instructions have been recorded correctly,
  the shareholder will also receive a confirmation of the voting instructions by
  mail

o A toll-free number will be available in case the voting information contained
  in the confirmation is incorrect

o If the shareholder decides after voting by telephone to attend the meeting,
  the shareholder can revoke the proxy at that time and vote the shares at the
  meeting

                                   EXHIBIT A


                      AGREEMENT AND PLAN OF REORGANIZATION

         THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as
of this ___ day of __________, 1999, by and between Pioneer Intermediate Tax-
Free Fund, a Massachusetts business trust with its principal place of business
at 60 State Street, Boston, Massachusetts 02109 (the "Acquired Fund"), and
Pioneer Tax-Free Income Fund (the "Acquiring Fund"), a Delaware business trust
with its principal place of business at 60 State Street, Boston, Massachusetts
02109.

         This Agreement is intended to be and is adopted as a plan of
reorganization within the meaning of Section 368(a)(1) of the United States
Internal Revenue Code of 1986, as amended (the "Code"). The reorganization will
consist of the transfer of all of the assets of the Acquired Fund to the
Acquiring Fund in exchange for the issuance of Class A, Class B and Class C
shares of beneficial interest of the Acquiring Fund (the "Acquiring Fund
Shares") to the Acquired Fund and the assumption by the Acquiring Fund of the
liabilities of the Acquired Fund, followed by the distribution by the Acquired
Fund, on or promptly after the Closing Date hereinafter referred to, of the
Acquiring Fund Shares to the shareholders of the Acquired Fund in liquidation
and termination of the Acquired Fund as provided herein, all upon the terms and
conditions hereinafter set forth in this Agreement.

         In consideration of the premises of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ACQUIRING FUND
     SHARES AND LIQUIDATION OF THE ACQUIRED FUND

     1.1 The Acquired Fund will transfer all of its assets (consisting, without
limitation, of portfolio securities and instruments, dividends and interest
receivables, cash and other assets), as set forth in the statement of assets and
liabilities referred to in paragraph 7.2 hereof (the "Statement of Assets and
Liabilities"), to the Acquiring Fund free and clear of all liens and
encumbrances, except as otherwise provided herein in exchange for (i) the
assumption by the Acquiring Fund of all known and unknown liabilities of the
Acquired Fund, including the liabilities set forth in the Statement of Assets
and Liabilities, which shall be assigned and transferred to and assumed by the
Acquiring Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund,
for distribution PRO RATA by the Acquired Fund to its shareholders in proportion
to their respective ownership of Class A, Class B and/or Class C shares of
beneficial interest of the Acquired Fund, as of the close of business on the
closing date (the "Closing Date"), of a number of Acquiring Fund Shares having
an aggregate net asset value equal to the value of the assets, less such
liabilities (herein referred to as the "net value of the assets"), of the
Acquired Fund so transferred,


<PAGE>


assumed, assigned and delivered, all determined as provided in paragraph 2
and as of a date and time as specified therein. Such transactions shall take
place at the closing provided for in paragraph 3.1 hereof (the "Closing"). All
computations shall be provided by Brown Brothers Harriman & Co. (the
"Custodian"), as custodian for the Acquiring Fund and for the Acquired Fund and
shall be recomputed by Arthur Andersen LLP, independent auditors of the
Acquiring Fund. The determination of the Custodian, as recomputed by said
auditors, shall be conclusive and binding on all parties in interest.

     1.2 The Acquired Fund has provided the Acquiring Fund with a list of the
current securities holdings of the Acquired Fund as of the date of execution of
this Agreement. The Acquired Fund reserves the right to sell any of these
securities (except to the extent sales may be limited by representations made in
connection with issuance of the tax opinion described in paragraph 8.7 hereof)
but will not, without the prior approval of the Acquiring Fund, acquire any
additional securities other than securities of the type in which the Acquiring
Fund is permitted to invest.

     1.3 Each of the Acquiring Fund and the Acquired Fund shall bear its own
expenses in connection with the transactions contemplated by this Agreement.

     1.4 On or as soon after the Closing Date as is conveniently practicable
(the "Liquidation Date"), the Acquired Fund will liquidate and distribute PRO
RATA to shareholders of record ("the Acquired Fund shareholders"), determined as
of the close of regular trading on the New York Stock Exchange on the last day
such Exchange is open for unrestricted trading immediately preceding the Closing
Date (the "Valuation Date"), the Acquiring Fund Shares received by the Acquired
Fund pursuant to paragraph 1.1. Such liquidation and distribution will be
accomplished by the transfer of the Acquiring Fund Shares then credited to the
account of the Acquired Fund on the books of the Acquiring Fund, to open
accounts on the share records of the Acquiring Fund in the names of the Acquired
Fund shareholders and representing the respective PRO RATA number of Acquiring
Fund Shares due such shareholders. Acquired Fund shareholders who own Class A
shares of the Acquired Fund will receive Class A Acquiring Fund Shares, Acquired
Fund shareholders who own Class B shares of the Acquired Fund will receive Class
B Acquiring Fund Shares and Acquired Fund shareholders who own Class C shares of
the Acquired Fund will receive Class C Acquiring Fund Shares. The Acquiring Fund
will not issue share certificates representing Acquiring Fund Shares unless a
shareholder specifically requests the Acquiring Fund Shares in certificated form
and, if applicable, in exchange for outstanding certificates representing
Acquired Fund shares, as described in paragraph 1.5.

     1.5 The Acquiring Fund shall record the net asset value of all outstanding
Acquired Fund certificated shares in its books and records as of the Closing
Date, in accordance with paragraph 2.2, and daily thereafter, in accordance with
the Acquiring


                                      -2-


<PAGE>


Fund's procedures for determining net asset value per share. The Acquiring
Fund will honor certificates representing Acquired Fund shares at their net
asset value as determined on the books and records of the Acquiring Fund, and
subject to the Acquiring Fund's normal requirements for redeeming or
transferring shares evidenced by certificates. Acquired Fund shareholders need
not surrender such certificates or deliver affidavits with respect to lost
certificates after the Closing. Any Acquired Fund certificate which remains
outstanding on the Closing Date shall be deemed to be evidence of ownership of
the same class of shares of beneficial interest of the Acquiring Fund.

     1.6 Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than the registered holder of the Acquiring Fund Shares on the books
of the Acquired Fund as of that time shall, as a condition of such issuance and
transfer, be paid by the person to whom such Acquiring Fund Shares are to be
issued and transferred.

     1.7 The Acquired Fund shall file an application (on Form N-8F or such other
form deemed appropriate by the Securities and Exchange Commission (the
"Commission")) pursuant to Section 8(f) of the Investment Company Act of 1940,
as amended (the "1940 Act"), as soon as practicable following the Liquidation
Date, and the existence of the Acquired Fund shall be terminated in accordance
with Massachusetts law as promptly as practicable thereafter.

2.   VALUATION

     2.1 The net asset values of the Class A, Class B and Class C Acquiring Fund
Shares and the net value of the assets and liabilities of the Acquired Fund
attributable to its Class A, Class B and Class C shares to be transferred shall,
in each case, be determined as of the close of the New York Stock Exchange on
the Valuation Date. The net asset value per share of Acquiring Fund Shares shall
be computed by the Custodian in the manner set forth in the Agreement and
Declaration of Trust or By-Laws of the Acquiring Fund and then-current
prospectus and statement of additional information of the Acquiring Fund and
shall be computed to not fewer than four decimal places. The net value of the
assets of the Acquired Fund to be transferred shall be computed by the Custodian
by calculating the value of the assets attributable to each class of shares
transferred by the Acquired Fund and by subtracting therefrom the amount of the
liabilities attributable to each class of shares to be assigned and transferred
to and assumed by the Acquiring Fund on the Closing Date, said assets and
liabilities to be valued in the manner set forth in the Acquired Fund's most
recent prospectus and statement of additional information.

     2.2 The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Fund's
assets shall be determined by dividing the value of the Acquired Fund assets
attributable to


                                      -3-


<PAGE>


a class, less the liabilities attributable to that class assumed by the
Acquiring Fund, by the Acquiring Fund's net asset value per share of the
same class, all as determined in accordance with paragraph 2.1.

     2.3 All computations of value shall be made by the Custodian in accordance
with its regular practice as pricing agent for the Acquiring Fund.

3.   CLOSING AND CLOSING DATE

     3.1 The Closing Date shall be as of ____________, 1999, or as of such other
date on or before ____________, 1999 as the parties may agree in writing. The
Closing shall be held at 5:00 p.m., Boston time, at the offices of the Acquiring
Fund, 60 State Street, Boston, Massachusetts 02109, or at such other time and/or
place as the parties may agree in writing.

     3.2 Portfolio securities that are not held in book-entry form in the name
of the Custodian as record holder for the Acquired Fund shall be presented by
the Acquired Fund to the Custodian for examination no later than five business
days preceding the Valuation Date. Portfolio securities which are not held in
book-entry form shall be delivered by the Acquired Fund to the Custodian for the
account of the Acquiring Fund on the Closing Date, duly endorsed in proper form
for transfer, in such condition as to constitute good delivery thereof in
accordance with the custom of brokers, and shall be accompanied by all necessary
federal and state stock transfer stamps or a check for the appropriate purchase
price thereof. Portfolio securities held of record by the Custodian in
book-entry form on behalf of the Acquired Fund shall be delivered to the
Acquiring Fund by the Custodian by recording the transfer of ownership thereof
on its records. The cash delivered shall be in the form of currency or by the
Custodian crediting the Acquiring Fund's account maintained with the Custodian
with immediately available funds.

     3.3 In the event that on the proposed Valuation Date (a) the New York Stock
Exchange shall be closed to trading or trading thereon shall be restricted, or
(b) trading or the reporting of trading on said Exchange or elsewhere shall be
disrupted so that accurate appraisal of the value of the net assets of the
Acquiring Fund or the Acquired Fund is impracticable, the Closing Date shall be
postponed until the first business day after the day when trading shall have
been fully resumed and reporting shall have been restored; provided that if
trading shall not be fully resumed and reporting restored on or before
________________, 1999, this Agreement may be terminated by the Acquiring Fund
or the Acquired Fund upon the giving of written notice to the other party.


     3.4 The Acquired Fund shall deliver at the Closing a list of the names,
addresses, federal taxpayer identification numbers and backup withholding and


                                      -4-


<PAGE>


nonresident alien withholding status of Acquired Fund shareholders and the
number and percentage ownership of outstanding shares of each class of shares of
beneficial interest of the Acquired Fund owned by each such shareholder, all as
of the close of business on the Valuation Date, certified by its Treasurer,
Secretary or other authorized officer (the "Shareholder List"). The Acquiring
Fund shall issue and deliver to the Acquired Fund a confirmation evidencing the
Acquiring Fund Shares to be credited on the Liquidation Date, or provide
evidence satisfactory to the Acquired Fund that such Acquiring Fund Shares have
been credited to the Acquired Fund's account on the books of the Acquiring Fund.
At the Closing each party shall deliver to the other such bills of sale, checks,
assignments, certificates, receipts or other documents as such other party or
its counsel may reasonably request.

The Lehman Brothers Municipal Bond Index is an unmanaged measure of
approximately 15,000 municipal bonds. Bonds in the Index have a minimum credit
rating of BBB, were part of at least a $50 million issuance made within the past
five years and have a maturity of at least two years. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in the Index.

Past performance does not guarantee future results. Return and share price
fluctuate, and your shares, when redeemed, may be worth more or less than their
original cost.

PIONEER INTERMEDIATE TAX-FREE FUND
PORTFOLIO MANAGEMENT DISCUSSION 6/30/98

Dear Shareowner,

Pioneer Intermediate Tax-Free Fund closed the first half of its fiscal year on
June 30, 1998. During that time, favorable economic conditions in the United
States and a "flight to quality" in the U.S. Treasury market pushed taxable bond
prices higher and long-term interest rates to historic lows. Even so, an
increased supply of municipal bonds combined with weak demand to restrain the
performance of munis, especially when compared to taxable bonds.

Kathleen D. McClaskey has managed Pioneer Intermediate Tax-Free Fund for the
past 11 years, leading the investment team responsible for the Fund's daily
management. In the following discussion, Ms. McClaskey reviews the investment
environment and the strategies that affected your Fund's performance and
provides her outlook for the second half of 1998.

Q:       HOW DID THE FUND PERFORM?

A: For the six month period ended June 30, the Fund's Class A shares returned
1.69%, Class B 1.29% and Class C 1.15%, all at net asset value. In comparison,
the 151 intermediate municipal debt funds followed by Lipper Analytical Services
returned 2.05% for the same period. (Returns do not reflect sales charges.) We
attribute your Fund's slight lag in performance to its investment standards.
Over the past six months, the Fund maintained an emphasis on higher-rated bonds.
Other funds in this category often invest in lower-rated bonds, which often
provide higher returns since they involve greater risk.

         The Fund's class A shares provided a tax-free 30-day yield of 3.31% on
June 30. That translated into an attractive taxable-equivalent yield of 5.49%
for an investor in the maximum 39.6% tax bracket.

Q:       DID THE SITUATION IN ASIA AFFECT U.S. INTEREST RATES AND BONDS?

A: The uncertainty of the Asian crisis kept interest rates, and bond
prices, within a narrow range for most of the period. It also sparked a "flight
to quality." Generally, investors waited for new developments and evidence of
the situation's effect on the U.S. economy. When the crisis worsened this
spring, investors sought the safety and security of U.S. Treasurys. This demand
again pushed up prices of taxable bonds and lowered interest rates.

         Asia's problems held down U.S. interest rates for another reason, too.
Many investors were concerned that our strong economy eventually might stimulate


                                       4


<PAGE>


inflation and lead the Federal Reserve to raise interest rates. But, because the
United States and Asia are active trading partners, slowing Asian economies
could lessen U.S. economic growth. That would ease inflationary pressures and
reduce the Fed's impetus to change rates.

Q:       WHAT WAS THE ENVIRONMENT LIKE FOR MUNICIPAL BONDS OVER THE PAST SIX
         MONTHS?

A: Basically it was a case of supply and demand. The supply of municipal bonds
increased dramatically during the first half of 1998, as many state and local
governments took advantage of lower interest rates to refinance existing bonds
or to finance new projects. In fact, this period included the largest
transaction ever to occur in the tax-exempt market - Long Island Power
Authority's $6.5 billion issue. Ironically, all this good news for
municipalities didn't help municipal bond investors much, since the flood of
supply kept prices from rising. In addition, the continuing economic problems in
Asia increased the popularity of U.S. Treasury bonds, particularly among foreign
investors. Municipal bond prices rose, but not as fast or far as Treasurys.

         The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on
December 31, 1997 to 5.63% on June 30. In comparison, the yield on the Lehman
Brothers Municipal Bond Index - a good indicator of the municipal bond market -
only fell from 4.70% on December 31 to 4.65% on June 30.

Q:       WHAT STRATEGIES DID YOU USE TO MANAGE THE FUND?

A: We sought to maximize income and total return by maintaining high standards
of quality and emphasizing relative value. During the period, lower-quality
bonds provided little yield advantage over higher rated bonds. In that scenario,
we believed higher-quality bonds represented better relative value.

         As of June 30, 90% of the Fund's holdings were rated AA or above,
translating into an average rating of "AA." (Ratings apply to underlying
securities, not Fund shares.) The portfolio remained well diversified with 57
holdings spread over 32 states.

         We increased total return potential by maintaining the portfolio's
duration - it rose slightly from 6.63 years on December 31 to 6.68 years on June
30. Duration measures a Fund's sensitivity to changes in interest rates.
Generally, an investment's price will change 1% for every 1% change in interest
rates. Higher durations mean more potential for both price appreciation when
interest rates fall and price declines when interest rates rise; shorter
durations reduce interest rate sensitivity.


                                       5

         We implemented this strategy by selling bonds with nearing "call dates"
and reinvesting in bonds with 15- to 20-year non-callable maturities. Call
provisions set a predetermined date for an issuer to repurchase a bond from its
holder. Often, this happens when interest rates decline so that an issuer can
refinance the bonds at lower rates. Selling callable bonds improved the Fund's
potential for both price appreciation and long-term income generation for
several reasons. Bonds with longer maturities offer better potential for price
appreciation when interest rates decline, and longer streams of predictable
income.

Q:       WHAT IS YOUR OUTLOOK FOR MUNICIPAL BONDS OVER THE NEXT SIX MONTHS?

A: Over the near-term, we expect many of the trends that were positive for
municipal bonds during the past six months to continue through the end of 1998.
We believe solid economic growth and minimal inflation in the United States can
spur ongoing improvement in the financial health of municipalities. After the
recent flood of offerings, we think issuers are taking a breather, which should
give tax-exempt bond prices a lift. Looking out further, we expect Asia to have
a powerful influence on interest rates. If there is a significant spillover into
the U.S. economy, interest rates could remain stable or move moderately lower.

The Lehman Brothers Municipal Bond Index is an unmanaged measure of
approximately 15,000 municipal bonds. Bonds in the Index have a minimum credit
rating of BBB, were part of at least a $50 million issuance made within the past
five years and have a maturity of at least two years. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in the Index.

A portion of the Fund's income may be subject to the Alternative Minimum Tax
(AMT).

Past performance does not guarantee future results. Return and share price
fluctuate, and your shares, when redeemed, may be worth more or less than their
original cost.

PIONEER TAX-FREE INCOME FUND
PORTFOLIO MANAGEMENT DISCUSSION 6/30/98

Dear Shareowner,

Pioneer Tax-Free Income Fund closed the first half of its fiscal year on June
30, 1998. During that time, favorable economic conditions in the United States
and a "flight to quality" in the U.S. Treasury market pushed taxable bond prices
higher and long-term interest rates to historic lows. Even so, an increased
supply of municipal bonds combined with weak demand, hurt the performance of
munis, especially when compared to taxable bonds.

Mark L. Winter has managed Pioneer Tax-Free Income Fund for the past 12 years,
leading the investment team responsible for the Fund's daily activities. The
following discussion with Mr. Winter details the investment environment and the
strategies that affected your Fund's performance, and provides his outlook for
the second half of 1998.

Q:       HOW DID THE FUND PERFORM IN THE FIRST HALF OF 1998?

A: Pioneer Tax-Free Income Fund delivered competitive returns. For the six
months, Class A Shares returned 2.46%, Class B Shares 2.16% and Class C Shares
2.08%, all at net asset value. In comparison, the 246 general municipal debt
funds followed by Lipper Analytical Services returned 2.26% for the same period.
(Returns do not reflect sales charges.) Lipper Analytical Services is an
independent company that tracks fund performance.

         The Fund's Class A Shares also provided a tax-free 30-day yield of
3.84% on June 30. That translated into an attractive taxable-equivalent yield of
6.35% for an investor in the 39.6% maximum federal tax bracket.

Q:       DID THE SITUATION IN ASIA AFFECT U.S. INTEREST RATES AND BONDS?

A: The uncertainty of the Asian crisis kept interest rates, and bond
prices, within a narrow range for most of the period. It also sparked a "flight
to quality." Generally, investors waited for new developments and evidence of
the situation's effect on the U.S. economy. When the crisis worsened this
spring, investors sought the safety and security of U.S. Treasuries. This demand
again pushed up prices of taxable bonds and lowered interest rates.

         Asia's problems held down U.S. interest rates for another reason, too.
Many investors were concerned that our strong economy eventually might stimulate
inflation and lead the Federal Reserve to raise interest rates. But, because the
United States and Asia are active trading partners, slowing Asian economies
could lessen


                                       10


<PAGE>


U.S. economic growth. That would ease inflationary pressures and reduce the
Fed's impetus to change rates.

Q:       WHAT WAS THE ENVIRONMENT LIKE FOR MUNICIPAL BONDS OVER THE PAST SIX
         MONTHS?

A: Basically it was a case of supply and demand. The supply of municipal bonds
increased dramatically during the first quarter of 1998, as many state and local
governments took advantage of lower interest rates to refinance higher-cost
bonds or to finance new projects. In fact, this period included the largest
transaction ever to occur in the tax-exempt market - Long Island Power
Authority's $6.5 billion issue. Ironically, all this good news for
municipalities didn't help municipal bond investors much since the flood of
supply kept prices from rising. In addition, the continuing economic problems in
Asia increased the popularity of U.S. Treasury bonds, particularly among foreign
investors. Municipal bond prices rose but not as fast or far as Treasury's.

         The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on
December 31, 1997 to 5.63% on June 30. In comparison, the yield on the Lehman
Brothers Municipal Bond Index - a good indicator of the municipal bond market -
only fell from 4.70% on December 31 to 4.65% on June 30.

Q:       WHAT STRATEGIES DID YOU USE TO MANAGE THE FUND?

A: We emphasized total return and income by adjusting the Fund's sensitivity to
interest rate changes. We also maintained the Fund's high standards of quality
and focused on attractive relative value. As of June 30, 54% of the Fund's
holdings were insured AAA-rated bonds, translating into an average rating of
"AA+." (Ratings apply to underlying securities, not Fund shares.) The portfolio
remained well diversified with 178 holdings spread over 41 states.

         We increased total return potential by increasing the portfolio's
duration from 6.44 years on December 31 to 7.70 years on June 30. Duration
measures a Fund's sensitivity to changes in interest rates. Generally, an
investment's price will change 1% for every 1% change in interest rates. Higher
durations mean more potential for both price appreciation when interest rates
fall and price declines when interest rates rise; shorter durations reduce
interest rate sensitivity.

         We implemented this strategy by selling bonds with nearing "call dates"
and reinvesting in bonds with 15 to 20 year maturities because "call" provisions
relate to a predetermined date for an issuer to repurchase a bond from its
holder. Often, this happens when interest rates decline so that an issuer can
refinance the bonds at lower rates. Selling callable bonds improved the Fund's
potential for both price appreciation and long-term income generation for
several reasons. Bonds with longer


                                       11


<PAGE>


maturities offer better potential for price appreciation when interest
rates decline, and longer streams of predictable income.

Q:       WHAT IS YOUR OUTLOOK FOR MUNICIPAL BONDS OVER THE NEXT SIX MONTHS?

A: Over the near-term, we expect many of the trends that were positive for
municipal bonds during the past six months to continue through the end of 1998.
We believe solid economic growth and minimal inflation in the United States can
spur ongoing improvement in the financial health of municipalities. After the
recent flood of offerings, we think issuers and taking a breather, which should
give tax-exempt bond prices a lift. Looking out further, we expect Asia to have
a powerful influence on interest rates. If there is a significant spillover into
the U.S. economy, interest rates could remain stable or move moderately lower.

A. Effective November 2, 1998, Pioneering Management Corporation ("PMC") will
change its name to Pioneer Investment Management, Inc. Wherever "Pioneering
Management Corporation" or "PMC" appears it is replaced by "Pioneer Investment
Management, Inc." or "Pioneer Investments," respectively.

B. The following is appended to the description of the Fund's Class B Plan:

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

         (i) to the extent required by a change in the Investment Company Act of
         1940 (the "1940 Act"), the rules or regulations under the 1940 Act, the
         Conduct Rules of the National Association of


<PAGE>


         Securities Dealers, Inc. (the "NASD") or an order of any court or
         governmental agency, in each case enacted, issued or promulgated after
         September 30, 1998;

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

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

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

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

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

          THIS STATEMENT OF ADDITIONAL INFORMATION IS NOT A PROSPECTUS
       AND IS AUTHORIZED FOR DISTRIBUTION TO PROSPECTIVE INVESTORS ONLY IF
               PRECEDED OR ACCOMPANIED BY AN EFFECTIVE PROSPECTUS.


<PAGE>


1.   INVESTMENT POLICIES AND RESTRICTIONS


     The Prospectus identifies the investment objective 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.
This Statement of Additional Information should be read in conjunction with the
Prospectus. Capitalized terms not otherwise defined herein have the meaning
given to them in the Prospectus.

PORTFOLIO MANAGEMENT

     The Fund intends to manage its portfolio fully by buying and selling
securities, as well as holding securities to maturity. In managing its portfolio
the Fund seeks to take advantage of market developments and yield disparities,
which may include use of the following strategies:

              (1)     shortening the average maturity of its portfolio in
     anticipation of a rise in interest rates so as to minimize depreciation of
     principal;

              (2) lengthening the average maturity of its portfolio in
     anticipation of a decline in interest rates so as to maximize tax-exempt
     yield;

              (3) selling one type of debt security (e.g., revenue bonds) and
     buying another (e.g., general obligation bonds) when disparities arise in
     the relative values of each; and

              (4) changing from one debt security to an essentially similar debt
     security when their respective yields appear distorted due to market
     factors.

     The Fund engages in portfolio trading if it believes a transaction net of
costs (including custodian charges) will help in achieving its investment
objective.

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 shares.
As used in the Prospectus and this Statement of Additional Information, such
approval means the approval of the lesser of (i) the holders of 67% or more of
the Fund's 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 Fund's outstanding shares.

     The Fund may not:

              (1) Borrow money, except as a temporary measure for extraordinary
     or emergency purposes, and then only in an amount not exceeding 10% of its
     gross assets, or pledge, mortgage or hypothecate an amount of its assets
     taken at market value which would exceed 15% of its gross assets, in each
     case taken at the lower of cost or market value and subject to a 300% asset
     coverage requirement;

              (2) Underwrite securities issued by other persons except insofar
     as the Fund may technically be deemed an underwriter under the Securities
     Act of 1933 in selling a portfolio security;

              (3) Purchase or sell real estate (including limited partnership
     interests, but excluding Municipal Bonds secured by real estate or
     interests therein), interests in oil, gas or mineral leases or


                                       2


<PAGE>


     exploration
     or development programs, commodities or commodity contracts (except
     contracts for the future acquisition or delivery of fixed-income
     securities) in the ordinary course of its business;


              (4) Make loans to other persons except through the use of
     repurchase agreements. The purchase of debt securities by the Fund pursuant
     to its investment objective and other investment policies shall not be
     considered loans for purposes of this restriction. Not more than 10% of its
     total assets will be invested in repurchase agreements maturing in more
     than seven days;

              (5) Purchase the securities of any issuer if such purchase, at the
     time thereof, would cause more than 5% of its total assets taken at market
     value to be invested in the securities of such issuer, other than
     securities issued or guaranteed by the U.S. government or its agencies or
     instrumentalities; or

              (6) Purchase any securities or evidences of interest therein on
     margin, except that the Fund may obtain such short-term credit as may be
     necessary for the clearance of purchases and sales of securities;

              The Fund will not purchase securities while any borrowings are
outstanding.

              Although the Fund may invest more than 25% of its assets in
     industrial development revenue bonds, the Fund will not purchase a security
     if, as a result, more than 25% of the Fund's assets would be in industrial
     revenue bonds where payment of principal and interest is the ultimate
     responsibility of issuers in the same industry.

              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:


     (a) Sell any security which the Fund does not own unless by virtue of its
     ownership of other securities it has at the time of sale a right to obtain
     securities without payment of further consideration equivalent in kind and
     amount to the securities sold and provided that if such right is
     conditional the sale is made upon the same conditions; or

     (b) 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.

     In addition, in connection with the offering of its shares in certain
jurisdictions, the Fund has agreed to adopt certain additional investment
restrictions which are not fundamental and may be changed by a vote of the
Fund's Board of Trustees. The Fund has agreed (1) that (i) short sales at any
one time shall not exceed 25% of the net equity of the Fund and (ii) the value
of any one issuer in which the Fund is short may not exceed the lesser of 2% of
the value of the Fund's net assets or 2% of the securities of any class of any
issuer; and (2) not to pledge, mortgage or hypothecate its portfolio securities
if the percentage of securities so pledged, mortgaged or hypothecated plus the
percentage of the sales charge on its shares would exceed 10%. In addition,
short sales may only be made in securities fully listed on a national stock
exchange.


                                       3

PERCENTAGE RESTRICTIONS

     If a percentage restriction on investment or utilization of assets set
forth above or in the Prospectus is adhered to at the time an investment is made
or assets are so utilized, a later change in percentage resulting from changes
in the value of the Fund's portfolio securities will not be considered a
violation of a policy.


     The Fund has adopted the following operating policies which are not
fundamental and which may be changed without shareholder approval. The Fund may
enter into repurchase agreements (a purchase of and a simultaneous commitment to
resell a security at an agreed upon price on an agreed upon date) with
broker-dealers and member banks of the Federal Reserve System and only if
collateralized by U.S. government securities. If the vendor of a repurchase
agreement fails to pay the sum agreed to on the agreed upon delivery date, the
Fund would have the right to sell the U.S. government securities, but might
incur a loss in so doing and in certain cases may not be permitted to sell the
U.S. government securities. As noted in Non-fundamental Investment Restriction
(b), the Fund may not invest more than 15% of its assets in illiquid securities
including repurchase agreements maturing in more than seven days. The Fund does
not anticipate investing more than 5% of its total assets in repurchase
agreements maturing in more than seven days in the foreseeable future.

     For the purposes of the Fund's investment restrictions, the issuer of a
tax-exempt security is deemed to be the entity (public or private) ultimately
responsible for the payment of the principal of, and interest on, the security.

COMPENSATION OF OFFICERS AND TRUSTEES


     The Fund pays no salaries or compensation to any of its officers. The Fund
pays an annual trustees' fee to each Trustee who is not affiliated with PGI,
PMC, PFD or PSC consisting of two components: (a) a base fee of $500 and (b) a
variable fee, calculated on the basis of the average net assets of the Fund. In
addition, the Fund pays a per meeting fee of $100 to each Trustee who is not
affiliated with PGI, PMC, PFD or PSC and pays an annual trustees' fee of $500
plus expenses to each Trustee affiliated with PGI, PMC, PFD or PSC. The Fund
also pays an annual committee participation fee to Trustees who serve as members
of committees established to act on behalf of one or more of the of Pioneer
mutual funds. Committee fees will be allocated to the Fund on the basis of the
Fund's average net assets. Each Trustee who is a member of the Audit Committee
for the Pioneer mutual funds receives an annual fee equal to 10% of the
aggregate annual trustees' fee, except the Committee Chair who receives an
annual trustees' fee equal to 20% of the aggregate annual trustees' fee. Members
of the Pricing Committee for the Pioneer mutual funds, as well as any other
committee which renders material functional services to the Boards of Trustees
for the Pioneer mutual funds, receives an annual fee equal to 5% of the annual
trustees' fee, except the Committee Chair who receives an annual trustees' fee
equal to 10% of the annual trustees' fee. Each Trustee who is not affiliated
with PGI, PMC, PFD or PSC also receives $375 per meeting for


                                       7


<PAGE>


attendance at meetings of the Non-Interested Trustees Committee, except for
the Committee Chair who receives an additional $375 per meeting. Any such fees
paid to interested Trustees are reimbursed to the Fund under its management
contract.

3.   INVESTMENT ADVISER


     The Fund has contracted with PMC, 60 State Street, Boston, Massachusetts
02109, to act as its investment adviser. The term of the contract is one year
and is renewable annually 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 a majority of the Fund's
outstanding voting securities and the giving of 60 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 willful misfeasance, bad faith or gross negligence in the performance
of its duties or by reason of its reckless disregard of its obligations and
duties under the management contract.

     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.
On an interim basis, PMC has agreed not to impose all or a portion of its
management fee and to make other arrangements, if necessary, to reduce Class A
expenses to 1.00% of the average daily net assets attributable to Class A
shares. The portion of Fund-wide expenses attributable to Class B and Class C
shares will be reduced only to the extent such expenses are reduced for Class A
shares. PMC's agreement is voluntary and temporary and may be revised or
terminated at any time.

     Pursuant to the expense limitation discussed above, during the fiscal years
ended December 31, 1997, 1996 and 1995, management fees were reduced by
$104,683, $87,136 and $89,114, respectively, resulting


                                       8


<PAGE>


in actual management fees paid during those periods to PMC of $246,524,
$309, 407 and $319,383, 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
laws. 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 each class of shares (the "Class A Plan," "Class B
Plan" and "Class C Plan") (together, the "Plans").

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 shares.

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.


                                       9

<PAGE>



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

CLASS C PLAN


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

     The purpose of distribution payments to PFD under the Class C Plan is to
compensate PFD for its distribution services with respect to 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.)
When a broker-dealer sells Class C shares and elects, with PFD's approval to
waive its right to receive the commission normally paid at the time of the sale,
PFD may cause all or a portion of the distribution fees described above to be
paid to the broker-dealer.

GENERAL


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

     No interested person of the Fund, nor any Trustee of the Fund who is not an
interested person of the Fund, has any direct or indirect financial interest in
the operation of the Plans except to the extent that PFD and certain of its
employees may be deemed to have such an interest as a result of receiving a


                                       10


<PAGE>


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 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 who 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 (as defined in the 1940
Act) of the respective class of the Fund. A Plan will automatically terminate in
the event of its assignment (as defined in the 1940 Act).

     During the fiscal year ended December 31, 1997, the Fund incurred total
distribution fees pursuant to the Fund's Class A Plan, Class B Plan and Class C
Plan of $159,818, $28,341 and $2,297, respectively. Distribution fees were paid
by the Fund to PFD in reimbursement of or as compensation for expenses related
to servicing shareholder accounts and to compensate dealers and sales personnel.

     Redemptions of each class of shares may be subject to a CDSC. A CDSC of
1.00% may be imposed on redemptions of certain net asset value purchases of
Class A shares within one year of purchase. Class B shares that are redeemed
within four years of purchase are subject to a CDSC at declining rates beginning
at 3.0% based on the lower of cost or market value of shares being redeemed.
Redemptions of Class C shares within one year of purchase are subject to a CDSC
of 1.00%. During the fiscal year ended December 31, 1997, CDSCs in the amount of
$4,065 were paid to PFD.

5.   SHAREHOLDER SERVICING/TRANSFER AGENT


     The Fund has contracted with PSC, 60 State Street, Boston, Massachusetts
02109, to act as shareholder servicing and transfer agent. This contract may be
terminated without penalty by either party upon 90 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 Fund shares; (ii) distributing dividends and capital gains
associated with Fund portfolio accounts; and (iii) maintaining account records
and responding to shareholder inquiries.

     PSC receives an annual fee of $30.00 per Class A, Class B and Class C
shareholder account from the Fund as compensation for the services described
above. PSC is also reimbursed by the Fund for its out-of-pocket expenditures.
This fee is set at an amount determined by vote of a majority of the 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 agreed to provide certain sub-accounting services such as
specific transaction processing and record keeping services. Any such payments
by the Fund would be in lieu of the per account fee which would otherwise be
paid by the Fund to PSC.

<PAGE>


6.   CUSTODIAN


     Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts
02109, is the custodian (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 in connection with the continuous offering of its
shares.

     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 or a merger or other reorganization.

     During the fiscal years ending December 31, 1997, 1996 and 1995, net
underwriting commissions retained by PFD were $5,138, $11,322 and $16,256,
respectively, in connection with its offering of Class A, Class B and Class C
shares. Commissions reallowed to dealers by PFD in the same periods were
$27,255, $207,180 and $116,073, respectively. See "Underwriting Agreement and
Distribution Plans" above for a description of the terms of the underwriting
agreement with PFD.

8.   INDEPENDENT PUBLIC ACCOUNTANTS


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

9.   PORTFOLIO TRANSACTIONS

     Decisions relating to the purchase and sale of securities for the Fund, the
allocation of portfolio transactions and, where applicable, the negotiation of
commission rates are made by officers of PMC.


     The primary consideration in placing portfolio security transactions is
execution at the most favorable prices. PMC has complete freedom as to the
markets in and broker-dealers through which it seeks this result. Municipal
Bonds and other debt securities are traded principally in the over-the-counter
market on a net basis through dealers acting for their own accounts and not as
brokers. The cost of securities purchased from underwriters includes an
underwriter's commission or concession, and the prices at which securities are
purchased and sold from and to dealers include a dealer's markup or markdown.
PMC attempts to negotiate with underwriters to decrease the commission or
concession for the benefit of the Fund. PMC normally seeks to deal directly with
the primary market makers unless, in its opinion, better prices are available
elsewhere.

     Subject to the requirement of seeking execution at the best available
price, securities may, as authorized by PMC's management contract, be bought
from or sold to dealers who furnish statistical research services and other
information or services to PMC and the Fund and/or other investment


                                       12

<PAGE>


companies managed by PMC, or who sell shares of any of the Pioneer mutual
funds. Brokerage and research 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, 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 or accounts 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 dealers solely because such services were
provided.

     The research received from broker-dealers may be useful to PMC in rendering
investment management services to the Fund as well as other investment companies
or other accounts managed by PMC, although not all such research may be useful
to the Fund. Conversely, such information provided by brokers or dealers who
have executed transaction orders on behalf of such other 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 addition to the Fund, PMC acts as investment adviser to other Pioneer
mutual funds and certain private accounts with investment objectives similar to
those of the Fund. As such, securities may frequently meet the investment
objectives of the Fund, such other funds and such private accounts. In such
cases, the decision to recommend a purchase to one fund or account rather than
another is based on a number of factors. The determining factors in most cases
are the amount of securities of the issuer then outstanding, the value of those
securities and the market for them. Other factors considered in the investment
recommendations include other investments which each fund or account presently
has in a particular industry and the availability of investment funds in each
fund or account.

     It is possible that at times identical securities will be held by more than
one fund and/or account. However, positions in the same issue may vary and the
length of time that any fund or account may choose to hold its investment in the
same issue may likewise vary. To the extent that the Fund, another Pioneer
mutual fund 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 fund or account, the resulting
participation in volume transactions could produce better executions for the
Fund or the 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.

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

10.  TAX STATUS


     It is the Fund's policy to meet the requirements of Subchapter M of the
Code for qualification as a regulated investment company. These requirements
relate to the sources of the Fund's income, the diversification of its assets
and the distribution of its income 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 earns, the Fund will be relieved of the necessity of paying
federal income tax.

     In order to qualify as a regulated investment company under Subchapter M,
the Fund must, among other things, derive at least 90% of its annual gross
income from interest, gains from the sale or other disposition of securities and
certain other income derived with respect to its business of investing in such
securities (the "90% income test") and satisfy certain annual distribution and
quarterly diversification requirements.

     In accordance with its investment objective, the Fund invests its assets in
a manner which will provide as large a portion of tax-exempt income as is
consistent with the protection of shareholders' capital. Since the protection of
capital is an important aspect of the Fund's investment objective, the Fund may
from time to time invest a portion of its portfolio in short-term obligations
and may engage in transactions generating gains or income which is not
tax-exempt, e.G., purchase non-municipal securities, sell or lend portfolio
securities, enter into repurchase agreements, dispose of rights to when-issued
securities prior to issuance, acquire any debt obligation at a market discount,
or acquire certain stripped tax-exempt obligations or their coupons. The Fund's
distributions from such gains or income will not be "exempt-interest dividends"
and, accordingly, will be taxable.

     The Code permits tax-exempt interest received by the Fund to flow through
as tax-exempt "exempt-interest dividends" to the Fund's shareholders, provided
that the Fund qualifies as a regulated investment company and at least 50% of
the value of the Fund's total assets at the close of each quarter of its taxable
year consists of tax-exempt obligations, i.e., obligations described in Section
103(a) of the Code. That part of the Fund's net investment income which is
attributable to interest from tax-exempt obligations and which is distributed to
shareholders will be designated by the Fund as an "exempt-interest dividend"
under the Code. Exempt-interest dividends are excluded from a shareholder's
gross income under the Code. The percentage of income designated as tax-exempt
is applied uniformly to all distributions made during each taxable year and may
differ from the actual tax-exempt percentage earned by the Fund during any
particular month. That portion of the Fund's dividends and distributions not
designated as tax-exempt will be taxable as described below.


     Dividends from investment company taxable income, which includes taxable
net investment income and net short-term capital gain in excess of net long-term
capital loss, 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 ("net capital gain"), if any, whether
received in cash or reinvested in additional shares, are taxable to the Fund's
shareholders as capital gains for federal income tax purposes without regard to
the length of time shares of the Fund have been held. As a result of the
enactment of the Taxpayer Relief Act of 1997 (the "1997 TRA") on August 5, 1997,
gain recognized after May 6, 1997 from the sale of a capital asset is taxable to
individual (noncorporate) investors at different maximum federal income tax
rates, depending generally upon the tax holding period for the asset, the
federal income tax bracket of the taxpayer, and the dates the asset was acquired
and/or sold. The Treasury Department has issued guidance under the 1997 TRA that
(subject to possible modification by future "technical corrections" legislation)
enables the Fund to pass through to its shareholders the benefits of the capital
gains tax rates enacted in the 1997 TRA. The Fund will provide appropriate
information to its shareholders about its distributions, including the tax
rate(s) applicable to its distributions from long-term capital gains, in
accordance with this and any future guidance. Shareholders should consult their
own tax advisers on the correct application of these new rules in their
particular circumstances.


                                       14


<PAGE>


     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.

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


     For federal income tax purposes, the Fund is permitted to carry forward a
net capital loss for any year to offset its capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent capital
gains are offset by such losses, they would not result in federal income tax
liability to the Fund and therefore are not expected to be distributed as such
to shareholders. As of the end of its most recent taxable year, the Fund had no
capital loss carryforwards.

     At the time of an investor's purchase of Fund shares, a portion of the
purchase price may be attributable to realized or unrealized appreciation in the
Fund's portfolio. Consequently, subsequent distributions by the Fund on these
shares 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
economically represent a return of a portion of the investment.

               Redemptions and exchanges are taxable events for shareholders
that are subject to tax. Shareholders should consult their own tax advisers with
reference to their individual circumstances to determine whether any particular
transaction in Fund shares is properly treated as a sale for tax purposes, as
the following discussion assumes, and the character of and tax rate applicable
to any gains or losses recognized in such transactions under the new rate
structure enacted in the 1997 TRA. Any loss realized by a shareholder on the
redemption, exchange, or other disposition of shares with a tax holding period
of six months or less will be disallowed to the extent of any exempt-interest
dividends paid with respect to such shares, and any portion of such loss that
exceeds the amount disallowed will be treated as a long-term capital loss to the
extent of any distributions treated as long-term capital gain with respect to
such shares.

     In addition, if Class A shares redeemed or exchanged have been held for
less than 91 days, (1) in the case of a reinvestment in the Fund 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 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
redemptions or other dispositions of shares may be disallowed under "wash sale"
rules in the event of other investments in the Fund (including those made
pursuant to reinvestment of dividends and/or capital gain distributions) within
a period of 61 days beginning 30 days before and ending 30 days after a
redemption or other disposition of shares. In such a case, the disallowed
portion of any loss would be included in the federal tax basis of the shares
acquired in the other investments.

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


                                       15


<PAGE>


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

     The exemption of exempt-interest dividends for federal income tax purposes
does not necessarily result in exemption under the tax laws of any state or
local taxing authority, which vary with respect to the taxation of such income.
Many states will exempt from tax that portion of an exempt-interest dividend
which represents interest received by the Fund on that state's securities,
subject in some cases to compliance with concentration and/or reporting
requirements, which the Fund makes no commitment to seek to satisfy. However,
the Fund will report annually to its shareholders the percentage of interest
income received by the Fund during the preceding year on federally tax-exempt
obligations indicating, on a state-by-state basis only, the source of such
income. Each shareholder is advised to consult his own tax adviser regarding the
exemption, if any, of exempt-interest dividends under the state and local laws
applicable to the shareholder.

     Interest on indebtedness incurred (directly or indirectly) by shareholders
to purchase or carry shares of the Fund will not be deductible for federal
income tax purposes to the extent it is deemed under the Code and applicable
regulations to relate to exempt-interest dividends received from the Fund.


     Federal law requires that the Fund withhold (as "backup withholding") 31%
of reportable payments, including taxable 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 Account
Applications, or on separate IRS Forms W-9, that the Social Security Number or
other Taxpayer Identification Number they provide is their correct number and
that they are not currently subject to backup withholding, or that they are
exempt from backup withholding. The Fund may nevertheless be required to
withhold if it receives notice from the IRS or a broker that the number provided
is incorrect or backup withholding is applicable as a result of previous
underreporting of interest or dividend income. Backup withholding may be
inapplicable for any year in which the Fund reasonably estimates that at least
95% of its dividends paid with respect to such year are exempt-interest
dividends.


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

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

11.  DESCRIPTION OF SHARES


     The Declaration 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 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 material amendment may be made to the Declaration without the
affirmative vote of a majority of its shares. Shares have no pre-emptive or
conversion rights. 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
the Declaration, a copy of which is on file with the office of the Secretary of
State of the Commonwealth of Massachusetts. Shareholders of a Massachusetts
business trust may, under certain circumstances, be held personally liable for
the obligations of the trust. However, the Declaration contains an express
disclaimer of shareholder liability for acts or obligations of the Fund and
provides that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Fund or its Trustees. Moreover,
the Declaration 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 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 further provides that the Fund shall indemnify each of its
Trustees and officers against liabilities and expenses reasonably incurred by
them, in connection with, or arising out of, any action, suit or proceeding,
threatened against or otherwise involving such Trustee or officer, directly or
indirectly, by reason of being or having been a Trustee or officer of the Fund.
The Declaration does not authorize the Fund to indemnify any Trustee or officer
against any liability to which he or she would 


                                       17


<PAGE>


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 (normally 4:00 p.m., Eastern time)
on each day on which the Exchange is open for trading. As of the date of this
Statement of Additional Information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day. The net asset value per share of each
class of the Fund is also determined on any other day in which the level of
trading in its portfolio 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. The net asset value per share of the Fund is not
determined on any day in which no purchase orders in good order for the shares
of the Fund are received and no shares are tendered for redemption.

     The net asset value per share of each class of the Fund is computed by
taking the value of all of the Fund's assets attributable to a class, less the
Fund's liabilities attributable to that class, and dividing the result by the
number of outstanding shares of the class. For purposes of determining net asset
value, expenses of the classes of the Fund are accrued daily.

     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 amortized 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 the 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. Periodic payments of $50 or more will be deposited monthly or quarterly
directly into a bank account designated by the applicant or will be sent by
check to the applicant, or any person designated by the applicant. Withdrawals
from Class B and Class C share accounts are limited to 10% of the value of the
account at the time the SWP is established. See "Waiver or Reduction of
Contingent Deferred Sales Charge" in the Prospectus. Designation of another
person to receive the payments subsequent to opening an account must be
accompanied by a signature guarantee.

     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.


                                       18


<PAGE>



     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 SWP account. Redemptions are potentially taxable transactions
to shareholders. 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 SWP have been redeemed.


15.  LETTER OF INTENT


         A Letter of Intent ("LOI") may be established by completing the LOI
section of the Account Application. When you sign the Account Application, you
agree to irrevocably appoint PSC your attorney-in-fact to surrender for
redemption any or all shares held in escrow with full power of substitution. An
LOI is not a binding obligation upon the investor to purchase, or the Fund to
sell, the full amount indicated.

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

         If the total purchases, less redemptions, are less than the amount
specified under the LOI, you must remit to PFD any difference between the sales
charge on the amount actually purchased and the amount originally specified in
the LOI section of the Account Application. When the difference is paid, the
shares held in escrow will be deposited to your account. If you do not pay the
difference in sales charge within 20 days after written request from PFD or your
dealer, PSC, after receiving instructions from PFD, will redeem the appropriate
number of shares held in escrow to realize the difference and release any
excess. See "How to Purchase Fund Shares - Letter of Intent" in the Prospectus
for more information.

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 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' yield
and/or total return to the Lehman Brothers Municipal Bond Index, 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 (such as individual securities, bank
deposits or certificates of deposit) and/or indices or indicators of economic
activity, e.g., inflation, interest rates, or the Consumer Price Index.

STANDARDIZED YIELD QUOTATIONS

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

              YIELD = 2[(a-b+1)6[superscript]-1]
                         ---
                          cd

Where:                a        =        interest earned during the period

                      b        =        net expenses accrued for the period

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

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

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

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

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

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

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


                                       20


<PAGE>


     (v) Obligations with sinking fund call provisions may be regarded as
maturing as to that portion to be retired on each sinking fund call date or
during a 12-month period; and

     (vi) In the case of a tax-exempt obligation issued without original issue
discount and having a current market discount, the coupon rate of interest of
the obligation is used in lieu of yield to maturity to determine interest income
earned on the obligation. In the case of a tax-exempt obligation with original
issue discount where the discount based on the current market value of the
obligation exceeds the then remaining portion of original issue discount (i.e.
market discount), the yield to maturity used to determine interest income earned
on the obligation is the imputed rate based on the original issue discount
calculation. In the case of a tax-exempt obligation with original issue discount
where the discount based on the current market value of the obligation is less
than the then remaining portion of the original issue discount (market premium),
the yield to maturity used to determine interest income earned on the obligation
is based on the market value of the obligation.


     The yields on Class A, Class B and Class C shares of the Fund for the
30-day period ended December 31, 1997 computed as above were 3.41%, 2.71% and
2.82%, respectively, except that absent expense limitations, the yields on Class
A, Class B and Class C shares of the Fund would have been 3.33%, 2.64% and
2.75%, respectively.

TAXABLE EQUIVALENT YIELD


     The Fund may also from time to time advertise the taxable equivalent yield
of a class which is determined by dividing that portion of the class' yield
(calculated as described above) that is tax exempt by one minus the stated
federal income tax rate and adding the product to that portion, if any, of the
class' yield that is not tax exempt. For a description of how to compare yields
on Municipal Bonds and taxable securities, see the APPENDIX to the Prospectus.
The taxable equivalent yields for a Class A shareholder, Class B shareholder and
Class C shareholder in the 39.6% federal income tax bracket for the one-month
period ended December 31, 1997 determined in accordance with such formula were
5.65%, 4.49% and 4.67%, respectively, except that absent expense limitations,
such tax-equivalent yields on Class A shares, Class B shares and Class C shares
of the Fund would have been 5.51%, 4.37% and 4.55%, respectively.

STANDARDIZED AVERAGE ANNUAL TOTAL RETURN QUOTATIONS


     One of the primary methods used to measure the performance of a class of
the Fund is "total return." Total return will normally represent the percentage
change in value of an account, or of a hypothetical investment in 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 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 will
usually be accompanied by total return percentages for each year within the
period and/or by the average annual compounded total return for the period. The
income and capital components of a given return may be separated and portrayed
in a variety of ways in order to illustrate their relative significance.
Performance may also be portrayed in terms of cash or investment values, without
percentages or by reference to historical information depicting the value of a
hypothetical account in the Fund since the Fund's inception. Past performance
cannot guarantee any particular future result.

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


                                       21


<PAGE>


redeemable value of such hypothetical investment on the last day of the
designated period in accordance with the following formula:

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

Where:    P   = a hypothetical initial payment of $1,000, less the
                maximum sales load of $35 for Class A shares or the
                deduction of any CDSC on Class B or Class C shares at
                the end of the period

          T   = average annual total return

          n   = number of years

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

     The computation above assumes 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 class' mean account size.

     The average annual total returns for Class A, Class B and Class C shares of
the Fund as of December 31, 1997 are as follows:

                                  AVERAGE ANNUAL TOTAL RETURN (%)

                   ONE YEAR     FIVE YEARS      TEN YEARS     SINCE INCEPTION*

Class A Shares       3.16          4.78            7.23             6.06
Class B Shares       3.08           N/A            N/A              4.94
Class C Shares       6.04           N/A            N/A              3.75



*Inception was October 22, 1986 for Class A shares; April 29, 1994 for Class B
shares; and January 31, 1996 for Class C shares.

     PMC temporarily agreed to reduce its management fee and made other
arrangements to limit certain other expenses of the Fund. Had PMC not made such
an arrangement, the total returns for the periods would have been lower.

                                   APPENDIX A

                         DESCRIPTION OF MUNICIPAL BONDS

     Municipal Bonds include debt obligations issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as bridges, highways, housing, mass transportation, schools, streets and
water and sewer works. Other public purposes for which Municipal Bonds may be
issued include refunding outstanding obligations, obtaining funds for general
operating expenses, and obtaining funds to loan to other public institutions.

     The two principal classifications of Municipal Bonds are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its faith, credit and taxing power for the payment for
principal and interest. The payment of such bonds may be dependent upon an
appropriation by the issuer's legislative body. The characteristics and
enforcement of general obligation bonds vary according to the law applicable to
the particular issuer. Revenue bonds are payable only from the revenues derived
from a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source. There are, of
course, variations in the security of Municipal Bonds, both within a particular
classification and between classifications, depending on numerous factors.


     The yields on Municipal Bonds are dependent on a variety of factors,
including general money market conditions, supply and demand and general
conditions of the Municipal Bond market, size of a particular offering, the
maturity of the obligation and rating of the issue. The ratings of Moody's
Investors Service, Inc. and Standard & Poor's Ratings Group represent their
opinions as to the quality of various Municipal Bonds. It should be emphasized,
however, that ratings are not absolute standards of quality. Consequently,
Municipal Bonds with the same maturity, coupon and rating may have different
yields while Municipal Bonds of the same maturity and coupon with different
ratings may have the same yield.

                          DESCRIPTION OF BOND RATINGS1

                         MOODY'S INVESTORS SERVICE, INC.


DEBT RATINGS - U.S. TAX-EXEMPT MUNICIPAL

There are nine basic rating categories for long-term obligations. They range
from Aaa (highest quality) to C (lowest quality). The Fund does not invest in
securities rated below Baa by Moody's or BBB by Standard Poor's. Moody's applies
numerical modifiers 1, 2, and 3 in each generic rating classification from Aa to
Baa. The modifier 1 indicates that the issue ranks in the higher end of its
generic rating category; the modifier 2 indicates a mid-range ranking; and the
modifier 3 indicates that the issue ranks in the lower end of its generic
category. Advance refunded issues that are secured by escrowed funds held in
cash, held in trust, reinvested in direct non-callable U.S. government
obligations or non-callable obligations unconditionally guaranteed by the U.S.
government are identified with a # symbol, e.g., #Aaa.

Aaa: Bonds that 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 that 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 that make the long-term risks appear somewhat larger than in Aaa
securities.

A: Bonds that 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 that
suggest susceptibility to impairment sometime in the future.

Baa: Bonds that 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.

Con. (...): Bonds for which the security depends upon the completion of some act
or the fulfillment of some condition are rated conditionally. These are bonds
secured by: (a) earnings of projects under construction, (b) earnings of
projects unseasoned in operating experience, (c) rentals that begin when
facilities are completed, or (d) payments to which some other limiting condition
attaches. Parenthetical rating denotes probable credit stature upon completion
of construction or elimination of basis of condition.

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

 1THE RATINGS INDICATED HEREIN ARE BELIEVED TO BE THE MOST RECENT RATINGS
 AVAILABLE AT THE DATE OF THIS STATEMENT OF ADDITIONAL INFORMATION FOR THE
 SECURITIES LISTED. RATINGS ARE GENERALLY GIVEN TO SECURITIES AT THE TIME OF
 ISSUANCE. WHILE THE RATING AGENCIES MAY FROM TIME TO TIME REVISE SUCH RATINGS,
 THEY UNDERTAKE NO OBLIGATION TO DO SO, AND THE RATINGS INDICATED DO NOT
 NECESSARILY REPRESENT RATINGS WHICH WILL BE GIVEN TO THESE SECURITIES ON THE
 DATE OF THE FUND'S FISCAL YEAR-END.

<PAGE>



                         STANDARD & POOR'S RATINGS GROUP




PUBLIC FINANCE - LONG-TERM ISSUE CREDIT RATINGS

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

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

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

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

PLUS (+) OR MINUS (-): The ratings from AA to BBB may be modified by the
addition of a plus or minus sign to show relative standing within the major
categories.

p: The letter "p" indicates that the rating is provisional. A provisional rating
assumes the successful completion of the project financed by the debt being
rated and indicates that payment of debt service requirements is largely or
entirely dependent upon the successful timely completion of the project.

L: The letter "L" indicates that the rating pertains to the principal amount of
those bonds to the extent that the underlying deposit collateral is federally
insured and interest is adequately collateralized. In the case of certificates
of deposit, the letter "L" indicates that the deposit, combined with other
deposits being held in the same right and capacity, will be honored for
principal and pre-default interest up to the federal insurance limits within 30
days after closing of the insured institution or, in the event that the deposit
is assumed by a successor insured institution, upon maturity.

r: The "r" is attached to highlight derivatives, hybrids and certain other
obligations that Standard & Poor's believes may experience high volatility or
high variability in expected returns as a result of noncredit risks. Examples of
such obligations are securities whose principal or interest return is indexed to
equities, commodities or other instruments. The absence of an "r" symbol should
not be taken as an indication that an obligation will exhibit no volatility or
variability in total return.

NR: Not rated.

                                   APPENDIX B

                    DESCRIPTION OF CERTAIN OTHER INVESTMENTS


     U.S. Government Obligations - are issued by the Treasury and include bills,
certificates of indebtedness, notes, and bonds. Agencies and instrumentalities
of the U.S. government are established under the authority of an act of Congress
and include, but are not limited to, the Government National Mortgage
Association, the Tennessee Valley Authority, the Bank for Cooperatives, the
Farmers Home Administration, Federal Home Loan Banks, Federal Intermediate
Credit Banks, Federal Land Banks, and the Federal National Mortgage Association.


     Certificates of Deposit - are certificates issued against funds deposited
in a commercial bank, are for a definite period of time, earn a specified rate
of return, and are normally negotiable.

     Bankers' Acceptances - are short-term credit instruments used to finance
the import, export, transfer or storage of goods. They are termed "accepted"
when a bank guarantees their payment at maturity.


     Repurchase Agreements - are agreements by which a person purchases a
security and simultaneously commits to resell that security to the seller (a
member bank of the Federal Reserve System or recognized securities dealer) at an
agreed upon price on an agreed upon date within a number of days (usually not
more than seven) from the date of purchase. The resale price reflects the
purchase price plus an agreed upon market rate of interest which is unrelated to
the coupon rate or maturity of the purchased security. A repurchase agreement
involves the obligation of the seller to pay the agreed upon price, which
obligation is in effect secured by the value of the underlying security, usually
U.S. government or government agency issues. Under the 1940 Act, repurchase
agreements are considered to be loans by the Fund. The Fund's risk is limited to
the ability of the seller to pay the agreed upon amount on the delivery date. In
the opinion of the Fund's adviser this risk is not material; if the seller
defaults, the underlying security constitutes collateral for the seller's
obligation to pay although the Fund may incur certain costs in liquidating this
collateral and in certain cases may not be permitted to liquidate this
collateral.

                             COMPARATIVE PERFORMANCE
                               INDEX DESCRIPTIONS


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

From 1926 to 1968 the total returns were calculated by summing the capital
appreciation returns and the income returns. For the period 1946 to 1968,
Ibbotson and Sinquefield backdated the Salomon Brothers' index, using Salomon
Brothers' monthly yield data with a methodology similar to that used by Salomon


                                       32


<PAGE>


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

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

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

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

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

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

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

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

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

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

          THIS STATEMENT OF ADDITIONAL INFORMATION IS NOT A PROSPECTUS
                AND IS AUTHORIZED FOR DISTRIBUTION TO PROSPECTIVE
            INVESTORS ONLY IF PRECEDED OR ACCOMPANIED BY AN EFFECTIVE
                                   PROSPECTUS.

1.       INVESTMENT OBJECTIVE AND POLICIES

         The Prospectus  identifies  the investment  objective and the principal
investment  policies of the Fund. Other investment  policies of the Fund are set
forth below.  Capitalized  terms not otherwise  defined  herein have the meaning
given to them in the Prospectus.

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

Municipal Lease Obligations

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

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

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

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

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

Zero Coupon and Deferred Interest Bonds

         Tax-Exempt  Bonds in which the Fund may invest also include zero coupon
bonds and deferred interest bonds. Zero coupon bonds and deferred interest bonds
are debt obligations which are issued at a significant discount from face value.
While zero  coupon  bonds do not  require  the  periodic  payment  of  interest,
deferred interest bonds provide for a period of delay before the regular payment
of interest begins.  The discount  approximates the total amount of interest the
bonds will  accrue and  compound  over the period  until  maturity  or the first
interest  payment date at a rate of interest  reflecting  the market rate of the
security at the time of issuance.  Zero coupon bonds and deferred interest bonds
benefit the issuer by  mitigating  its need for cash to meet debt  service,  but
also  require a higher  rate of return to attract  investors  who are willing to
defer receipt of such cash. Such investments may experience  greater  volatility
in value than debt obligations which make regular payments of interest. The Fund
will accrue income on such investments for tax and accounting purposes, which is
distributable to shareholders. Since no cash is received at the time of accrual,
the Fund may be required to liquidate other portfolio  securities to satisfy its
distribution obligations.

Residual Interests in Municipal Securities

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

Options

         The  Fund  can  write  (sell)   "covered"   put  and  call  options  on
fixed-income  securities.  Call options  written by the Fund give the holder the
right to buy the underlying  securities  from the Fund at a fixed exercise price
up to a stated expiration date or, in the case of certain options, on such date.
Put options written by the Fund give the holder the right to sell the securities
to the Fund  during  the term of the  option at a fixed  exercise  price up to a
stated  expiration date or, in the case of certain  options,  on such date. Call
options are  "covered"  by the Fund,  for example,  when it owns the  underlying
securities  which the option  holder has the right to purchase,  and put options
are  "covered" by the Fund,  for example,  when it has  established a segregated
account of cash or short-term money market  instruments  which can be liquidated
promptly  to satisfy  any  obligation  of the Fund to  purchase  the  underlying
securities.  The Fund will  receive a premium from writing a put or call option,
which  increases  the  Fund's  gross  income  in the event  the  option  expires
unexercised or is closed out at a profit.

         By writing a call  option,  the Fund limits its  opportunity  to profit
from any  increase  in the market  value of the  underlying  security  above the
exercise price of the option. By writing a put option, the Fund assumes the risk
that it may be required  to purchase  the  underlying  security  for an exercise
price  higher  than its then  current  market  value,  resulting  in a potential
capital loss unless the security subsequently appreciates in value.

         The Fund could  terminate  an option that it has  written  prior to its
expiration  by  entering  into a  "closing  purchase  transaction"  in  which it
purchases an option having the same terms as the option written. It is possible,
however, that illiquidity in the options markets may make it difficult from time
to time for the Fund to close out its written option  positions.  The Fund could
also purchase put or call options in  anticipation  of changes in interest rates
which  may  adversely  affect  the  value  of its  portfolio  or the  prices  of
securities that the Fund wants to purchase at a later date. The premium paid for
a put or call option plus any transaction costs will reduce the benefit, if any,
realized by the Fund upon exercise of the option,  and,  unless the price of the
underlying security changes sufficiently, the option may expire without value to
the Fund.

         The Fund intends to write and purchase options on securities  primarily
for hedging purposes and also in an effort to increase  current income.  Options
on securities  that are written or purchased by the Fund will be entered into on
U.S.  securities  exchanges  regulated by the Securities and Exchange Commission
("SEC")  and  in  the  over-the-counter  market.  Over-the-counter  transactions
involve certain risks which may not be present in an exchange  environment.  The
staff of the SEC has taken the position that purchased  over-the-counter options
and assets used to cover  written  over-the-counter  options are  illiquid  and,
therefore,  together  with other  illiquid  securities,  cannot  exceed 15% of a
Fund's net assets.

Futures Contracts and Options on Futures Contracts

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

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

         When interest  rates are rising or securities  prices are falling,  the
Fund can  seek to  offset  a  decline  in the  value  of its  current  portfolio
securities  through  the sale of  futures  contracts.  When  interest  rates are
falling or  securities  prices are rising,  the Fund,  through  the  purchase of
futures contracts, can attempt to secure better rates or prices than might later
be available in the market when it effects anticipated purchases.

         Positions  taken  in the  futures  markets  are  not  normally  held to
maturity but are instead liquidated  through  offsetting  transactions which may
result  in a  profit  or a loss.  A  clearing  corporation  associated  with the
exchange on which futures on  securities  are traded  guarantees  that, if still
open, the sale or purchase will be performed on the settlement date.

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

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

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

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

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

         The Fund may use options on futures  contracts for bona fide hedging or
non-hedging purposes as discussed below.

         Other  Considerations.  The Fund will  engage in  futures  and  related
options  transactions  only for bona fide  hedging or  non-hedging  purposes  in
accordance  with CFTC  regulations  which  permit  principals  of an  investment
company  registered  under the  Investment  Company Act of 1940, as amended (the
"1940 Act"),  to engage in such  transactions  without  registering as commodity
pool  operators.  The Fund is not  permitted  to engage in  speculative  futures
trading.  The Fund will  determine  that the price  fluctuations  in the futures
contracts  and options on futures used for hedging  purposes  are  substantially
related to price fluctuations in securities held by the Fund or which it expects
to purchase.  Except as stated below,  the Fund's futures  transactions  will be
entered into for traditional hedging purposes -- i.e., futures contracts will be
sold to protect against a decline in the price of securities that the Fund owns,
or futures  contracts  will be purchased to protect the Fund against an increase
in the price of securities  it intends to purchase.  As evidence of this hedging
intent,  the Fund expects that on 75% or more of the occasions on which it takes
a long futures or option position (involving the purchase of futures contracts),
the  Fund  will  have  purchased,  or  will  be in the  process  of  purchasing,
equivalent amounts of related securities in the cash market at the time when the
futures or option position is closed out. However,  in particular cases, when it
is economically  advantageous for the Fund to do so, a long futures position may
be  terminated  or an option may expire  without the  corresponding  purchase of
securities or other assets.

         As an  alternative  to literal  compliance  with the bona fide  hedging
definition,  a CFTC  regulation  permits  the  Fund to elect  to  comply  with a
different test, under which the sum of the amounts of initial margin deposits on
the  Fund's  existing  non-hedging  futures  contracts  and  premiums  paid  for
non-hedging  options on futures  (net of the  amount the  positions  are "in the
money")  would not exceed 5% of the market  value of the Fund's net assets.  The
Fund will engage in  transactions  in futures  contracts and options only to the
extent such  transactions  are consistent with the  requirements of the Internal
Revenue Code of 1986, as amended (the "Code"), for maintaining its qualification
as a regulated investment company for federal income tax purposes.

         Transaction costs associated with futures contracts and related options
involve  brokerage costs,  require margin deposits and, in the case of contracts
and  options  obligating  the Fund to purchase  securities,  require the Fund to
segregate assets to cover such contracts and options.

         While  transactions  in futures  contracts  and  options on futures may
reduce certain risks, such  transactions  themselves entail certain other risks.
Thus, while the Fund may benefit from the use of futures and options on futures,
unanticipated  changes in interest  rates or  securities  prices may result in a
poorer  overall  performance  for the Fund than if it had not  entered  into any
futures  contracts  or  options  transactions.  In  the  event  of an  imperfect
correlation  between  a  futures  position  and a  portfolio  position  which is
intended to be  protected,  the desired  protection  may not be obtained and the
Fund may be exposed to risk of loss.  The only  futures  contracts  available to
hedge the Fund's  portfolio are various futures on U.S.  Government  securities,
futures on a municipal securities index and stock index futures.

Tax-Exempt Bonds

         Tax-Exempt  Bonds include debt  obligations  issued to obtain funds for
various public  purposes,  including the  construction of a wide range of public
facilities  such  as  airports,  bridges,  highways,  housing,  hospitals,  mass
transportation,  schools,  streets,  and  water and sewer  works.  Other  public
purposes  for which  Tax-Exempt  Bonds may be issued  include the  refunding  of
outstanding obligations, obtaining funds for general operating expenses, and the
obtaining  of funds to loan to other  public  institutions  and  facilities.  In
addition,  certain types of industrial development bonds are, or have been under
prior  law,  issued by or on behalf of  public  authorities  to obtain  funds to
provide privately-operated housing facilities, sports facilities,  convention or
trade show facilities,  airports, mass transit, port or parking facilities,  air
or water pollution  control  facilities,  and certain local facilities for water
supply, gas,  electricity,  or sewage or solid waste disposal.  Such obligations
are  included  within the term  Tax-Exempt  Bonds if the  interest  paid thereon
qualifies as excluded from gross income for federal  income tax purposes.  Other
types of industrial  development  bonds,  the proceeds of which are used for the
construction,  equipment, repair or improvement of privately operated industrial
or commercial facilities,  may constitute Tax-Exempt Bonds, although the current
federal tax laws place substantial limitations on the size of such issues.

         The two  principal  classifications  of  Tax-Exempt  Bonds are "general
obligation" and "revenue"  bonds.  General  obligation  bonds are secured by the
issuer's  pledge of its  faith,  credit  and  taxing  power for the  payment  of
principal and interest. Revenue bonds are payable only from the revenues derived
from a particular  facility or class of facilities  or, in some cases,  from the
proceeds  of a  special  excise or other  specific  revenue  source.  Industrial
development bonds which are Tax-Exempt Bonds are in most cases revenue bonds and
do not  generally  constitute  the  pledge of the  credit of the  issuer of such
bonds.  There are, of course,  variations in security of Tax-Exempt  Bonds, both
within a particular  classification  and between  classifications,  depending on
numerous factors.


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


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

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


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


2.       INVESTMENT RESTRICTIONS


         Fundamental  Investment  Restrictions.  The  Fund has  adopted  certain
investment restrictions which may not be changed without the affirmative vote of
the holders of a "majority of the outstanding voting securities" ( as defined in
the 1940 Act) of the Fund. The Fund may not:

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

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

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

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

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

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

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

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

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

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

         If a percentage  restriction on investment or utilization of assets set
forth in any of the above is adhered  to at the time an  investment  is made,  a
later change in percentage  resulting  from  changing  values or a change in the
rating of a portfolio security will not be considered a violation of policy.

4. INVESTMENT ADVISER As stated in the Prospectus, PMC, 60 State Street, Boston,
Massachusetts  02109,  serves as the Fund's investment  adviser.  PMC became the
Fund's  investment  adviser on December 1, 1993.  Prior to that date,  Mutual of
Omaha Fund Management  Company ("FMC") served as the Fund's investment  adviser.
The management  contract is renewable  annually 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 Trustees or a majority of its  outstanding  voting
securities and the giving of 60 days' written notice.

         As compensation for its management services and expenses incurred,  PMC
is entitled to a management  fee at the following  rates per annum of the Fund's
average  daily  net  assets.  The fee is  computed  and  accrued  daily and paid
monthly.

For assets up to $250,000,000                      0.50%

fee that would have been payable  under the previous  management  contract  with

management contract with FMC, which was terminated on December 1, 1993, the Fund

5.       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 certain
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 each Class of shares  (the  "Class A Plan",
"Class B Plan" and "Class C Plan") (together, the "Plans").

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 the  Class A  shares.  Certain  categories  of such  expenditures  have  been
approved by the Board of Trustees and are set forth in the Prospectus  under the
caption  "Distribution  Plans." 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 the
Class A shares,  the annual rate of 0.25% of the Fund's average daily net assets
attributable to Class A shares.

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




Class C Plan


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


         The purpose of  distribution  payments to PFD under the Class C Plan is
to  compensate  PFD for its  distribution  services  with respect to 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.)
When a broker-dealer  sells Class C shares and elects,  with PFD's approval,  to
waive its right to receive the commission normally paid at the time of the sale,
PFD may cause all or a portion of the  distribution  fees described  above to be
paid to the broker-dealer.



General

         In accordance with the terms of 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
appropriateness  and the  level  of  reimbursement  or  compensation  the  Plans
provide.

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


         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,  as  defined  in the 1940 Act (none of whom had or have any
direct or indirect financial interest in the operation of the Plan) of the Fund,
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  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 to 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 (as defined in the 1940
Act) of the respective Class of the Fund. A Plan will automatically terminate in
the event of its  assignment  (as  defined  in the 1940 Act).  In the  Trustees'
quarterly   review  of  the  Plans,   they  will  consider  a  Plan's  continued
appropriateness and the level of compensation it provides.

     During the fiscal year ended  December 31, 1997,  the Fund  incurred  total
distribution  fees pursuant to the Fund's Class A Plan, Class B Plan and Class C
Plan of $1,052,278,,  $50,451 and $9,515, respectively. 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 December 31, 1997, CDSCs, in the amount of approximately $24,904 were paid
to PFD.




6.       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 upon 90 days' written notice.


         Under  the  terms of its  contract  with  the  Fund,  PSC will  service
shareholder  accounts,  and its  duties  will  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 $30.00 per Class A, Class B and Class C
shareholder  account from the Fund as  compensation  for the services  described
above.  PSC is also reimbursed by the Fund for its  out-of-pocket  expenditures.
This fee is set at an amount  determined  by vote of a majority of the  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 agreed to provide certain sub-accounting  services,  such as
specific transaction processing and recordkeeping services. Any such payments by
the Fund would be in lieu of the per account fee which would  otherwise  be paid
by the Fund to PSC.



7.       CUSTODIAN


         Brown Brothers Harriman & Co., 40 Water Street,  Boston,  Massachusetts
02109, is the custodian (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  also provides
fund accounting, bookkeeping and pricing assistance to the Fund.


         The Custodian does not determine the investment policies of the Fund or
decide which  securities it will buy or sell.  The Fund may invest in securities
issued  by the  Custodian,  deposit  cash in the  Custodian  and  deal  with the
Custodian as a principal in securities transactions. Portfolio securities may be
deposited into the Federal Reserve-Treasury  Department Book Entry System or the
Depository Trust Company.

8.       PRINCIPAL UNDERWRITER


         PFD,  60 State  Street,  Boston,  Massachusetts  02109,  serves  as the
principal underwriter for the Fund in connection with the continuous offering of
the Class A, Class B and Class C shares of the Fund.

         During the Fund's fiscal years ending  December 31,  1995,1996 and 1997
net underwriting  commissions retained by PFD in connection with the offering of
Fund  shares  were  $99,407,  $77,023  and  $50,526,  respectively.  Commissions
reallowed  to  dealers  by PFD in those  periods  were  $754,315,  $531,201  and
$348,767, respectively.


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

9.       INDEPENDENT PUBLIC ACCOUNTANT

         Effective  January 1, 1994,  Arthur  Andersen LLP 225 Franklin  Street,
Boston,  Massachusetts  02110, was selected as the independent public accountant
for the Fund,  providing audit services,  tax return review,  and assistance and
consultation   with  respect  to  the  preparation  of  filings  with  the  SEC.
Previously, Coopers & Lybrand had served as independent public accountant to the
Fund. Arthur Andersen's  election as independent public accountant was approved,
at a meeting called for the purpose of voting on such approval, by the vote of a
majority  of those  Trustees  on the Board of  Trustees  who are not  interested
persons of the Fund.

10.      PORTFOLIO TRANSACTIONS

         All orders for the purchase or sale of portfolio  securities are placed
on behalf of the Fund by PMC  pursuant  to  authority  contained  in the  Fund's
Management  Contract.  In selecting  broker-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 broker-dealer; the broker-dealer's execution services
rendered on a continuing  basis;  and the  reasonableness  of any  broker-dealer
spreads.

         PMC may select  broker-dealers  which provide brokerage and/or research
services to the Fund and/or  other  investment  companies  managed by PMC or who
sell shares of the Pioneer mutual funds. In addition,  if PMC determines in good
faith that the amount of commissions charged by a broker-dealer is reasonable in
relation to the value of the  brokerage and research  services  provided by such
broker-dealer,  the Fund may pay commissions to such  broker-dealer in an amount
greater  than the amount  another  firm may charge.  Such  services  may include
advice  concerning the value of securities;  the  advisability  of investing in,
purchasing  or  selling  securities;  the  availability  of  securities  or  the
purchasers or sellers of securities;  furnishing analyses and reports concerning
issuers, industries, securities, economic factors and trends, portfolio strategy
and  performance  of  accounts;   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.

         The  research  received  from  broker-dealers  may be  useful to PMC in
rendering investment management services to the Fund as well as other investment
companies  managed by PMC,  although not all such  research may be useful to the
Fund. Conversely,  such information provided by broker-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.

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

         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 shares of the Fund.


         In addition to the Fund,  PMC acts as investment  adviser or subadviser
to the other Pioneer mutual funds,  Pioneer  Interest Shares and certain private
accounts  with  investment  objectives  similar to that of the Fund.  Securities
frequently meet the investment  objective of the Fund, such other funds and such
private  accounts.  In such cases,  the  decision to recommend a purchase to one
fund or  account  rather  than  another  is based on a number  of  factors.  The
determining  factors in most cases are the  amount of  securities  of the issuer
then  outstanding,  the value of those securities and the market for them. Other
factors considered in the investment  recommendations  include other investments
which each mutual fund or account presently has in a particular industry and the
availability of investment funds in each mutual fund or account.

         It is possible that at times identical  securities will be held by more
than one mutual fund and/or  account.  However,  positions in the same issue may
vary and the length of time that any mutual  fund or account  may choose to hold
its investment in the same issue may likewise vary. To the extent that the Fund,
another  Pioneer  mutual  fund,  Pioneer  Interest  Shares or a private  account
managed by PMC may not be able to acquire as large a position  in such  security
as it desires,  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  mutual  fund  or  account,  the  resulting  participation  in  volume
transactions could produce better executions for the Fund or the account. In the
event more than one  account  purchases  or sells the same  security  on a given
date,  the purchases and sales will normally be made as nearly as practicable on
a pro rata basis in proportion to the amounts desired to be purchased or sold by
each.


         The Fund paid no  brokerage  commissions  for the  fiscal  years  ended
December 31, 1994, 1995 and 1996.


11.         TAX STATUS

It is the Fund's  policy to meet the  requirements  of Subchapter M of the Code,
for qualification as a regulated  investment company.  These requirements relate
to the sources of the Fund's income,  the  diversification of its assets and the
distribution  of  its  income  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 earns,  the Fund will be relieved of the  necessity  of paying
federal income tax.

In order to qualify as a regulated  investment  company under  Subchapter M, the
Fund must,  among other  things,  derive at least 90% of its annual gross income
from interest, payments with respect to securities loans, gains from the sale or
other  disposition of securities or other income  (including  gains from options
and futures contracts) derived with respect to its business of investing in such
securities (the "90% income  test")and  satisfy certain annual  distribution and
quarterly diversification requirements.


In accordance with its investment  objectives,  the Fund invests its assets in a
manner  which  will  provide  as large a  portion  of  tax-exempt  income  as is
consistent with the protection of shareholders' capital. Since the protection of
capital is an important aspect of the Fund's investment objectives, the Fund may
from time to time invest a portion of its  portfolio in  short-term  obligations
and  may  engage  in  transactions  generating  gains  or  income  which  is not
tax-exempt,  e.g.,  purchase  non-municipal  securities,  sell or lend portfolio
securities,  enter into repurchase agreements,  dispose of rights to when-issued
securities prior to issuance,  acquire any debt obligation at a market discount,
acquire certain stripped  tax-exempt  obligations or their coupons or enter into
options and futures  transactions.  The Fund's  distributions from such gains or
income  will  not be  "exempt-interest  dividends"  and,  accordingly,  will  be
taxable.


The Code  permits  tax-exempt  interest  received by the Fund to flow through as
tax-exempt "exempt-interest dividends" to the Fund's shareholders, provided that
the Fund  qualifies  as a regulated  investment  company and at least 50% of the
value of the Fund's  total  assets at the close of each  quarter of its  taxable
year consists of tax-exempt obligations,  i.e., obligations described in Section
103(a) of the Code.  That part of the  Fund's  net  investment  income  which is
attributable to interest from tax-exempt obligations and which is distributed to
shareholders  will be  designated by the Fund as an  "exempt-interest  dividend"
under the Code.  Exempt-interest  dividends  are excluded  from a  shareholder's
gross income under the Code. The  percentage of income  designated as tax-exempt
is applied uniformly to all distributions  made during each taxable year and may
differ  from the  actual  tax-exempt  percentage  earned by the Fund  during any
particular  month.  That portion of the Fund's dividends and  distributions  not
designated as tax-exempt will be taxable as described below.


Dividends from investment  company taxable  income,  which includes  taxable net
investment  income and net  short-term  capital gain in excess of net  long-term
capital  loss,  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 ("net capital  gain"),  if any,  whether
received in cash or reinvested in 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.  As a result of
the  enactment of the Taxpayer  Relief Act of 1997 (the "1997 TRA") on August 5,
1997,  gain  recognized  after May 6,  1997 from the sale of a capital  asset is
taxable to  individual  (noncorporate)  investors at different  maximum  federal
income tax rates, depending generally upon the tax holding period for the asset,
the  federal  income tax  bracket of the  taxpayer,  and the dates the asset was
acquired and/or sold. The Treasury Department has issued guidance under the 1997
TRA that (subject to possible  modification  by future  "technical  corrections"
legislation) enable the Fund to pass through to its shareholders the benefits of
the  capital  gains tax rates  enacted  in the 1997 TRA.  The Fund will  provide
appropriate  information to its shareholders about its distributions,  including
the tax rate(s)  applicable  to its  distributions  from its  long-term  capital
gains,  in accordance  with this and any future  guidance.  Shareholders  should
consult their own tax advisers on the correct  application of these new rules in
their particular  circumstances.  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.


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

For federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss for any year to offset its capital gains,  if any, during the eight
years following the year of the loss. To the extent subsequent capital gains are
offset by such losses,  they would not result in federal income tax liability to
the  Fund  and  therefore  are  not  expected  to  be  distributed  as  such  to
shareholders.  As of the end of its most recent  taxable  year,  the Fund had no
capital loss carryforwards.


At the time of an investor's  purchase of Fund shares, a portion of the purchase
price may be attributable  to realized or unrealized  appreciation in the Fund's
portfolio.  Consequently,  subsequent  distributions by the Fund on these shares
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  economically
represent a return of a portion of the investment.

Redemptions and exchanges are taxable events for  shareholders  that are subject
to tax.  Shareholders  should  consult their own tax advisers with  reference to
their individual  circumstances to determine whether any particular  transaction
in Fund shares is properly treated as a sale for tax purposes,  as the following
discussion assumes, and the character of and tax rate applicable to any gains or
losses recognized in such  transactions  under the new rate structure enacted in
the 1997 TRA. Any loss realized by a shareholder on the redemption, exchange, or
other disposition of shares with a tax holding period of six months or less will
be disallowed to the extent of any  exempt-interest  dividends paid with respect
to such shares,  and any portion of such loss that exceeds the amount disallowed
will be treated as a long-term  capital loss to the extent of any  distributions
treated as long-term capital gain with respect to such shares.

In addition,  if Class A shares  redeemed or  exchanged  have been held for less
than 91 days, (1) in the case of a  reinvestment  in the Fund 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 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
redemptions or other  dispositions of shares may be disallowed under "wash sale"
rules in the  event of other  investments  in the  Fund  (including  those  made
pursuant to reinvestment of dividends and/or capital gain distributions)  within
a  period  of 61 days  beginning  30 days  before  and  ending  30 days  after a
redemption  or other  disposition  of  shares.  In such a case,  the  disallowed
portion of any loss would be  included  in the  federal  tax basis of the shares
acquired in the other investments.

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


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

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

The exemption of exempt-interest  dividends for federal income tax purposes does
not  necessarily  result in  exemption  under the tax laws of any state or local
taxing authority,  which vary with respect to the taxation of such income.  Many
states will exempt from tax that portion of an  exempt-interest  dividend  which
represents interest received by the Fund on that state's securities,  subject in
some cases to compliance with concentration and/or reporting requirements, which
the Fund makes no commitment to seek to satisfy.  However,  the Fund will report
annually to its  shareholders  the percentage of interest income received by the
Fund during the preceding year on federally tax-exempt  obligations  indicating,
on a state-by-state  basis only, the source of such income.  Each shareholder is
advised to consult  his own tax  adviser  regarding  the  exemption,  if any, of
exempt-interest  dividends  under the state and  local  laws  applicable  to the
shareholder.

Interest on  indebtedness  incurred  (directly or indirectly) by shareholders to
purchase or carry shares of the Fund will not be deductible  for federal  income
tax  purposes  to  the  extent  it is  deemed  under  the  Code  and  applicable
regulations to relate to exempt-interest dividends received from the Fund.

Federal law requires  that the Fund  withhold (as "backup  withholding")  31% of
reportable payments, including taxable 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  Account  Applications,  or on
separate  IRS Forms  W-9,  that the  Social  Security  Number or other  Taxpayer
Identification Number they provide is their correct number and that they are not
currently  subject to backup  withholding,  or that they are exempt  from backup
withholding.  The Fund may  nevertheless  be required to withhold if it receives
notice from the IRS or a broker that the number  provided is incorrect or backup
withholding is applicable as a result of previous  underreporting of interest or
dividend  income.  Backup  withholding may be inapplicable for any year in which
the Fund  reasonably  estimates  that at least  95% of its  dividends  paid with
respect to such year are exempt-interest dividends.


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


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


12.      DESCRIPTION OF SHARES

General

         The Fund is an open-end  investment  company  established as a Nebraska
corporation in 1968 and  reorganized as a Delaware  business trust in June 1994.
Prior to December 1, 1993 the Fund was called  Mutual of Omaha  Tax-Free  Income
Fund,  Inc. and prior to June 30, 1994 was called Pioneer  Tax-Free Income Fund,
Inc.  Reference to the Fund  includes both the Delaware  business  trust and the
Nebraska corporation. The Board of Trustees, as of the date of this Statement of
Additional Information,  has authorized the issuance of three classes of shares,
Class A, Class B and Class C.

         Unless otherwise  required by the 1940 Act or the Declaration of Trust,
the  Fund  has  no  intention  of  holding  annual  meetings  of   shareholders.
Shareholders may remove a Trustee by the affirmative vote of at least two-thirds
of the Fund's  outstanding shares and the Trustees shall promptly call a meeting
for such purpose when requested to do so in writing by the record holders of not
less than 10% of the  outstanding  shares of the Fund.  Shareholders  may, under
certain  circumstances  communicate  with other  shareholders in connection with
requesting a special  meeting of  shareholders.  However,  at any time that less
than a majority of the Trustees holding office were elected by the shareholders,
the  Trustees  will call a special  meeting of  shareholders  for the purpose of
electing Trustees.

         The  Declaration  of Trust  permits the issuance of series of shares in
addition to the Fund which would represent  interests in separate  portfolios of
investments.  No series  would be  entitled  to share in the assets of any other
series or be liable for the expenses or liabilities of any other series.

         In addition to the requirements  under Delaware law, the Declaration of
Trust provides that  shareholders  of the Fund may bring a derivative  action on
behalf of the Fund only if the following  conditions  are met: (a)  shareholders
eligible to bring such  derivative  action under  Delaware law who hold at least
10% of the outstanding  shares of the Fund, or 10% of the outstanding  shares of
the series or class to which such action relates,  shall join in the request for
the Trustees to commence  such action;  and (b) the Trustees  must be afforded a
reasonable  amount  of  time  to  consider  such  shareholder   request  and  to
investigate  the basis of such claim.  The Trustees  shall be entitled to retain
counsel or other  advisers  in  considering  the merits of the request and shall
require an undertaking by the shareholders  making such request to reimburse the
Fund for the  expense  of any  such  advisers  in the  event  that the  Trustees
determine not to bring such action.

Shareholder and Trustee Liability

         The Fund is organized as a Delaware business trust, and, under Delaware
law, the shareholders of such a trust are not generally subject to liability for
the debts or obligations of the trust. Similarly, Delaware law provides that the
Fund will not be liable for the debts or  obligations of any other series of the
trust.  However, no similar statutory or other authority limiting business trust
shareholder  liability exists in many other states.  As a result,  to the extent
that a Delaware  business trust or a shareholder is subject to the  jurisdiction
of courts in such other  states,  the courts may not apply  Delaware law and may
thereby subject the Delaware business trust shareholders to liability.  To guard
against this risk, the  Declaration  of Trust contains an express  disclaimer of
shareholder  liability  for acts or  obligations  of the  Fund.  Notice  of such
disclaimer  will normally be given in each  agreement,  obligation or instrument
entered  into or executed  by the Fund or a Trustee.  The  Declaration  of Trust
provides for  indemnification by the Fund for any loss suffered by a shareholder
as a result of an obligation 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.  The Trustees  believe that, in view of the above, the risk of personal
liability of shareholders is remote.

         The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment  or  mistakes  of fact or law,  but nothing in the
Declaration of Trust protects a Trustee against any liability to which he or she
would otherwise be subject by reason of willful  misfeasance,  bad faith,  gross
negligence,  or reckless  disregard of the duties involved in the conduct of his
or her office.


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  (normally 4:00 p.m., Eastern
time) on each day the  Exchange  is open  for  business.  As of the date of this
Statement of  Additional  Information,  the Exchange is open for business  every
weekday except for the following  holidays:  New Year's Day,  Martin Luther King
Jr. Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence  Day, Labor
Day,  Thanksgiving  Day and Christmas Day. The net asset value per share of each
class of the Fund is also  determined  on any  other  day in which  the level of
trading in its portfolio  securities is  sufficiently  high that the current net
asset  value per share might be  materially  affected by changes in the value of
its portfolio securities.  On any day in which no purchase orders for the shares
of the Fund become  effective  and no shares are  tendered for  redemption,  the
Fund's net asset value per share may not be determined.

         The net asset  value per share of each class of the Fund is computed by
taking the value of all of the Fund's assets  attributable to a class,  less its
liabilities attributable to that class, and dividing the result by the number of
outstanding  shares of the class.  For purposes of determining  net asset value,
expenses of the classes of the Fund are accrued daily and taken into account.


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

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.  Periodic  checks  of $50 or more  will be  deposited
monthly or quarterly  directly into a bank account  designated by the applicant,
or will be sent by check to the  applicant,  or to any person  designated by the
applicant.  A  designation  of a third  party to receive  payments  requires  an
acceptable  signature  guarantee.  SWPs for Class B and C share accounts will be
limited to 10% of the value of the account at the time the SWP is implemented as
described in the  Prospectus.  See "Waiver or Reduction of  Contingent  Deferred
Sales Charge" in the Prospectus.



         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.  Redemptions are taxable  transactions
to shareholders.  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 SWP
account. 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 SWP  have  been
redeemed.

15.      LETTER OF INTENT (Class A only)

A Letter of Intent  ("LOI") may be  established by completing the LOI section of
the Account  Application.  When you sign the Account  Application,  you agree to
irrevocably appoint PSC your attorney-in-fact to surrender for redemption any or
all  shares  held in escrow  with full  power of  substitution.  An LOI is not a
binding obligation upon the investor to purchase,  or the Fund to sell, the full
amount indicated.

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

If the total  purchases,  less  redemptions,  are less than the amount specified
under the LOI, you must remit to PFD any difference  between the sales charge on
the amount  actually  purchased and the amount  originally  specified in the LOI
section of the Account Application. When the difference is paid, the shares held
in escrow will be deposited to your account. If you do not pay the difference in
sales charge within 20 days after written request from PFD or your dealer,  PSC,
after receiving  instructions  from PFD, will redeem the  appropriate  number of
shares held in escrow to realize the difference and release any excess. See "How
to  Purchase  Fund  Shares  -  Letter  of  Intent"  in the  Prospectus  for more
information.


16.  INVESTMENT RESULTS

         Other 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 its
yield and total return to the Shearson  Lehman Hutton  Municipal Bond Index,  or
other comparable indices or investment vehicles. In addition, the performance of
the Fund may be compared to alternative  investment or savings vehicles (such as
individual securities, bank deposits, or certificates of deposit) and/or indices
or indicators of economic  activity,  e.g.,  inflation,  interest  rates, or the
Consumer Price Index,  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 any such  publication) or used for comparison,  as well as performance
listings and rankings  from various other  sources  including CDA  Weisenberger,
Donoghue's  Mutual  Fund  Almanac,   Investment  Company  Data,  Inc.,  Ibbotson
Associates,  Johnson's Charts, Kanon Bloch Carre and Company,  Lipper Analytical
Services,  Inc.,  Micropal,  Inc.,  Morningstar,   Inc.,  Schabacker  Investment
Management and Towers Data Systems, Inc.

         In addition,  from time to time quotations from articles from financial
publications  such as those listed above may be used in  advertisements in sales
literature,  or in  reports  to  shareholders  of the  Fund.  The  Fund may also
present,  from time to time,  historical  information  depicting  the value of a
hypothetical  account  in one or more  classes  of the  Fund  since  the  Fund's
inception.

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

         One of the  methods  used to measure the Fund's  performance  is "total
return." "Total return" will normally  represent the percentage  change in value
of an account,  or of a hypothetical  investment in the Fund, over any period up
to the lifetime of the Fund. Total return  calculations  will usually assume the
reinvestment  of all  dividends  and  capital  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 will
usually be  accompanied  by total  return  percentages  for each year within the
period and/or by the average annual compounded total return for the period.  The
income and capital  components  of a given return may be separated and portrayed
in a  variety  of ways in  order  to  illustrate  their  relative  significance.
Performance may also be portrayed in terms of cash or investment values, without
percentages.
Past performance cannot guarantee any particular future result.

         Other data that may be advertised  or published  about the Fund include
the average portfolio quality,  the average portfolio maturity,  and the average
portfolio duration.

         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 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 are calculated by standard methods prescribed by the SEC.

         Standardized Yield Quotations

         Yield  quotations  for Class A, Class B and Class C shares are computed
by dividing the net investment income per share attributable to a class during a
base period of 30 days, or one month, by the maximum offering price per share of
that class of the Fund 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;

         (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;

         (v)  Obligations  with sinking fund call  provisions may be regarded as
maturing  as to that  portion to be retired  on each  sinking  fund call date or
during a twelve-month period; and

         (vi) In the case of a tax exempt  obligation  issued  without  original
issue discount and having a current market discount, the coupon rate of interest
of the  obligation  is used in lieu of yield to maturity to  determine  interest
income earned on the  obligation.  In the case of a tax exempt  obligation  with
original  issue discount where the discount based on the current market value of
the  obligation  exceeds the then  remaining  portion of original issue discount
(i.e. market discount),  the yield to maturity used to determine interest income
earned  on the  obligation  is the  imputed  rate  based on the  original  issue
discount calculation. In the case of a tax exempt obligation with original issue
discount  where the discount based on the current market value of the obligation
is less than the then remaining  portion of the original issue discount  (market
premium),  the yield to maturity used to determine interest income earned on the
obligation is based on the market value of the obligation.


         The  Fund's  30-day  SEC yield for Class A shares,  Class B shares  and
Class C shares on December 31, 1997,  determined in accordance  with the formula
above, was 3.94%, 3.32% and 3.17%, respectively.


         Taxable Equivalent Yield


         The Fund may also from time to time  advertise  its taxable  equivalent
yield  which  is  determined  by  dividing  that  portion  of the  Fund's  yield
(calculated  as  described  above)  that is tax  exempt by one minus the  stated
federal  income tax rate and adding the product to that portion,  if any, of the
Fund's yield that is not tax exempt. The Fund's  tax-equivalent yield assuming a
39.6% tax rate for the period ended December 31, 1997 was 6.52%,  5.50%and 5.25%
for Class A  shares,  Class B shares,  and Class C shares,  respectively.  For a
description of how to compare yields on municipal bonds and taxable  securities,
see the Taxable Equivalent Formula set forth in Appendix A to the Prospectus.


Standardized Average Annual Total Return Quotations

         Average  annual  total  return  quotations  are computed by finding the
average  annual  compounded  rates of return  that  would  cause a  hypothetical
investment  made on the first  day of a  designated  period 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 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

         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 of
a particular Class are taken into consideration.  For any account fees that vary
with the size of the  account,  the account  fee used for  purposes of the above
computation  is assumed  to be the fee that would be charged to the Class'  mean
account size.


         The average  annual total returns for period  ending  December 31, 1997
were:

                                   APPENDIX A

         The three highest  ratings of Moody's for Tax-Exempt  Bonds are Aaa, Aa
and A.  Tax-Exempt  Bonds rated Aaa are judged to be of the "best  quality." The
rating of Aa is assigned to  Tax-Exempt  Bonds which are of "high quality by all
standards,"  but as to  which  margins  of  protection  or other  elements  make
long-term risks appear somewhat larger than Aaa rated Tax-Exempt  Bonds. The Aaa
and Aa rated  Tax-Exempt  Bonds comprise what are generally known as "high grade
bonds."  Tax-Exempt  Bonds which are rated A by Moody's  possess many  favorable
investment  attributes  and are  considered  "upper  medium grade  obligations."
Factors giving  security to principal and interest of A rated  Tax-Exempt  bonds
are  considered   adequate,   but  elements  may  be  present  which  suggest  a
susceptibility to impairment sometime in the future.  Bonds in the A group which
offer the maximum security are rated A-1.

         The three highest ratings of S&P for Tax-Exempt  Bonds are AAA (Prime),
AA (High Grade) and A (Good Grade).  Tax-Exempt Bonds rated AAA are "obligations
of the highest  quality."  The rating of AA is accorded  issues with  investment
characteristics  "only  slightly  less  marked  than those of the prime  quality
issues." The category of A describes the "third  strongest  capacity for payment
of debt service."  Principal and interest payments on bonds in this category are
regarded as safe. It differs from the two higher ratings  because:  with respect
to general obligation bonds, there is some weakness either in the local economic
base, in debt burden,  in the balance between revenues and  expenditures,  or in
quality  of  management.  Under  certain  adverse  circumstances,  any one  such
weakness might impair the ability of the issuer to meet debt obligations at some
future date. With respect to revenue bonds,  debt service  coverage is good, but
not  exceptional.  Stability of the pledged  revenues could show some variations
because of increased  competition  or economic  influences  on  revenues.  Basic
security  provisions,  while  satisfactory,   are  less  stringent.   Management
performance appears adequate. AA and A rated bonds may be modified with a (+) or
(-) when appropriate to provide more detailed indications on credit quality.

         The "other debt  securities"  included in the  definition  of temporary
investments are corporate (as opposed to municipal)  debt obligation  rated AAA,
AA or A by S&P or Aaa, Aa or A by Moody's.  Corporate debt obligations rated AAA
by S&P are "highest  grade  obligations."  Obligations  bearing the rating of AA
also  qualify as "high grade  obligations"  and "in the  majority  of  instances
differ from AAA issues only in small degree." Corporate debt obligations rates A
by S&P are regarded as "upper  medium grade" and have  "considerable  investment
strength,  but are not entirely free from adverse effects of changes in economic
and trade  conditions."  The Moody's  corporate debt ratings of Aaa, Aa and A do
not differ materially from those set forth above for Tax-Exempt Bonds.

         The  commercial  paper ratings of A-1 by S&P and P-1 by Moody's are the
highest  commercial  paper  ratings of the  respective  agencies.  The  issuer's
earnings,  quality of long-term debt, management and industry position are among
the factors considered in assigning such ratings.

         Subsequent to its purchase by the Fund, an issue of Tax-Exempt Bonds or
a temporary  investment may cease to be rated or its rating may be reduced below
the minimum  required  for  purchase by the Fund.  Neither  event  requires  the
elimination of such obligation from the Fund's portfolio,  but PMC will consider
such an event in its  determination  of whether the Fund should continue to hold
such obligation in its portfolio. To the extent that the ratings accorded by S&P
and Moody's for Tax-Exempt Bonds or temporary investments may change as a result
of changes in such organizations,  or changes in their ratings systems, the Fund
will attempt to use  comparable  ratings as  standards  for its  investments  in
Tax-Exempt  Bonds or temporary  investments  in accordance  with the  investment
policies contained herein.

                             COMPARATIVE PERFORMANCE
                               INDEX DESCRIPTIONS

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

BANK SAVINGS ACCOUNT
Data sources include the U.S. League of Savings Institutions Sourcebook; average

LETTER FROM THE CHAIRMAN 6/30/98
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

While the Taxpayer Relief Act of 1997 provided lower rates on capital gains, it
did not ease the tax burden on investment income. As a result, municipal bonds
remain one of the few effective ways for investors to protect themselves from
taxes. We are happy to offer Pioneer Interme-diate Tax-Free Fund as a choice for
conservative, tax-sensitive investors. The Fund's professional management and
diversified portfolio make tax-free investing affordable and accessible, an
important point since municipal bonds can be difficult for individuals to buy
and sell directly. Although municipal bonds did not keep pace with the snappy
gains posted by taxable U.S. government and corporate bonds over the past six
months, they generated solid returns and attractive after-tax dividends.

We have always recommended that investors diversify their portfolios among
different types of both stocks and bonds. Recent market volatility has
underscored this point. What can you as an investor do? I encourage you to
periodically review your financial goals and strategy with your investment
professional. It's a simple step to make sure you will be better prepared to
weather the inevitable swings in the market.

Please read on to learn more about how your Fund is being managed. If you have
questions about Pioneer Intermediate Tax-Free Fund, please contact your
investment professional, or Pioneer at 1-800-225-6292.

Respectfully,

/s/ John F. Cogan, Jr.,

The Lehman Brothers Municipal Bond Index is an unmanaged measure of
approximately 15,000 municipal bonds. Bonds in the Index have a minimum credit
rating of BBB, were part of at least a $50 million issuance made within the past
five years and have a maturity of at least two years. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in the Index.

Past performance does not guarantee future results. Return and share price
fluctuate, and your shares, when redeemed, may be worth more or less than their
original cost.

PORTFOLIO MANAGEMENT DISCUSSION 6/30/98
- --------------------------------------------------------------------------------

Dear Shareowner,

Pioneer Intermediate Tax-Free Fund closed the first half of its fiscal year on
June 30, 1998. During that time, favorable economic conditions in the United
States and a "flight to quality" in the U.S. Treasury market pushed taxable bond
prices higher and long-term interest rates to historic lows. Even so, an
increased supply of municipal bonds combined with weak demand to restrain the
performance of munis, especially when compared to taxable bonds. 

Kathleen D. McClaskey has managed Pioneer Intermediate Tax-Free Fund for the
past 11 years, leading the investment team responsible for the Fund's daily
management. In the following discussion, Ms. McClaskey reviews the investment
environment and the strategies that affected your Fund's performance and
provides her outlook for the second half of 1998.

Q:    How did the Fund perform?

A:    For the six month period ended June 30, the Fund's Class A shares returned
      1.69%, Class B 1.29% and Class C 1.15%, all at net asset value. In
      comparison, the 151 intermediate municipal debt funds followed by Lipper
      Analytical Services returned 2.05% for the same period. (Returns do not
      reflect sales charges.) We attribute your Fund's slight lag in performance
      to its investment standards. Over the past six months, the Fund maintained
      an emphasis on higher-rated bonds. Other funds in this category often
      invest in lower-rated bonds, which often provide higher returns since they
      involve greater risk.

      The Fund's class A shares provided a tax-free 30-day yield of 3.31% on
      June 30. That translated into an attractive taxable-equivalent yield of
      5.49% for an investor in the maximum 39.6% tax bracket.

Q:    Did the situation in Asia affect U.S. interest rates and bonds?

A:    The uncertainty of the Asian crisis kept interest rates, and bond prices,
      within a narrow range for most of the period. It also sparked a "flight to
      quality." Generally, investors waited for new developments and evidence
      of the situation's effect on the U.S. economy.

      When the crisis worsened this spring, investors sought the safety and
      security of U.S. Treasurys. This demand again pushed up prices of taxable
      bonds and lowered interest rates.

      Asia's problems held down U.S. interest rates for another reason, too.
      Many investors were concerned that our strong economy eventually might
      stimulate inflation and lead the Federal Reserve to raise interest rates.
      But, because the United States and Asia are active trading partners,
      slowing Asian economies could lessen U.S. economic growth. That would ease
      inflationary pressures and reduce the Fed's impetus to change rates.

Q:    What was the environment like for municipal bonds over the past six
      months?

A:    Basically it was a case of supply and demand. The supply of municipal
      bonds increased dramatically during the first half of 1998, as many state
      and local governments took advantage of lower interest rates to refinance
      existing bonds or to finance new projects. In fact, this period included
      the largest transaction ever to occur in the tax-exempt market - Long
      Island Power Authority's $6.5 billion issue. Ironically, all this good
      news for municipalities didn't help municipal bond investors much, since
      the flood of supply kept prices from rising. In addition, the continuing
      economic problems in Asia increased the popularity of U.S. Treasury bonds,
      particularly among foreign investors. Municipal bond prices rose, but not
      as fast or far as Treasurys.

      The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on
      December 31, 1997 to 5.63% on June 30. In comparison, the yield on the
      Lehman Brothers Municipal Bond Index - a good indicator of the municipal
      bond market - only fell from 4.70% on December 31 to 4.65% on June 30. 

Q:    What strategies did you use to manage the Fund?

A:    We sought to maximize income and total return by maintaining high
      standards of quality and emphasizing relative value. During the period,
      lower-quality bonds provided little yield advantage over higher rated
      bonds. In that scenario, we believed higher-quality bonds represented
      better relative value.


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 6/30/98                              (continued)
- --------------------------------------------------------------------------------

      As of June 30, 90% of the Fund's holdings were rated AA or above,
      translating into an average rating of "AA." (Ratings apply to underlying
      securities, not Fund shares.) The portfolio remained well diversified with
      57 holdings spread over 32 states.

      We increased total return potential by maintaining the portfolio's
      duration - it rose slightly from 6.63 years on December 31 to 6.68 years
      on June 30. Duration measures a Fund's sensitivity to changes in interest
      rates. Generally, an investment's price will change 1% for every 1% change
      in interest rates. Higher durations mean more potential for both price
      appreciation when interest rates fall and price declines when interest
      rates rise; shorter durations reduce interest rate sensitivity.

      We implemented this strategy by selling bonds with nearing "call dates"
      and reinvesting in bonds with 15 - to 20 - year non-callable maturities.
      Call provisions set a predetermined date for an issuer to repurchase a
      bond from its holder. Often, this happens when interest rates decline so
      that an issuer can refinance the bonds at lower rates. Selling callable
      bonds improved the Fund's potential for both price appreciation and
      long-term income generation for several reasons. Bonds with longer
      maturities offer better potential for price appreciation when interest
      rates decline, and longer streams of predictable income.

Q:    What is your outlook for municipal bonds over the next six months?

A:    Over the near-term, we expect many of the trends that were positive for
      municipal bonds during the past six months to continue through the end of
      1998. We believe solid economic growth and minimal inflation in the United
      States can spur ongoing improvement in the financial health of
      municipalities. After the recent flood of offerings, we think issuers are
      taking a breather, which should give tax-exempt bond prices a lift.
      Looking out further, we expect Asia to have a powerful influence on
      interest rates. If there is a significant spillover into the U.S. economy,
      interest rates could remain stable or move moderately lower.

Pioneer Intermediate Tax-Free Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/98
- --------------------------------------------------------------------------------

1.    Organization and Significant Accounting Policies

Pioneer Intermediate Tax-Free Fund (the Fund) is a Massachusetts business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to seek a
high level of current income exempt from federal income taxes.

The Fund offers three classes of shares - Class A, Class B, and Class C shares.
Shares of Class A, Class B, and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and has exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B, and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:

A.    Security Valuation

      Security transactions are recorded on trade date. Securities are valued at
      prices supplied by independent pricing services, which consider such
      factors as Treasury spreads, yields, maturities and ratings, and
      valuations may be supplemented by dealers and other sources, as required.
      Market discount and premium are accreted or amortized daily on a
      straight-line basis. Original issue discount is accreted daily into
      interest income on a yield-to-maturity basis with a corresponding increase
      in the cost basis of the security. Interest income is recorded on the
      accrual basis. Temporary cash investments are valued at amortized cost.

      Gains and losses on sales of investments are calculated on the identified
      cost method for both financial reporting and federal income tax purposes.
      It is the Fund's practice to first select for sale those securities that
      have the highest cost and also qualify for long-term capital gain or loss
      treatment for tax purposes.

Pioneer Intermediate Tax-Free Fund

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

B.    Federal Income Taxes

      It is the Fund's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its taxable income and net realized capital gains, if
      any, to its shareholders. Therefore, no federal income tax provision is
      required.

      The characterization of distributions to shareholders for financial
      reporting purposes is determined in accordance with federal income tax
      rules. Therefore, the source of the Fund's distributions may be shown in
      the accompanying financial statements as either from or in excess of net
      investment income or net realized gain on investment transactions, or from
      paid-in capital, depending on the type of book/tax differences that may
      exist.

C.    Fund Shares

      The Fund records sales and repurchases of its shares on trade date. Net
      losses, if any, as a result of cancellations are absorbed by Pioneer Funds
      Distributor, Inc. (PFD), the principal underwriter for the Fund and an
      indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $1,984 in
      underwriting commissions on the sale of the fund shares during the six
      months ended June 30, 1998.

D.    Class Allocations

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A, Class B, and Class C shares of the Fund,
      respectively. Shareholders of each class share all expenses and fees paid
      to the transfer agent, Pioneering Services Corporation (PSC), for their
      services, which are allocated based on the number of accounts in each
      class and the ratable allocation of related out-of-pocket expense (see
      Note 3). Income, common expenses and realized and unrealized gains and
      losses are calculated at the Fund level and allocated daily to each class
      of shares based on the respective percentage of adjusted net assets at the
      beginning of the day.

      The Fund declares as daily dividends substantially all of its net
      investment income. All dividends are paid on a monthly basis. Short-term
      capital gain distributions, if any, may be declared with the daily
      dividends. Distributions to shareholders are recorded as of the
      ex-dividend date. Distributions paid by the Fund with respect to each
      class of shares are calculated in the same manner, at the same time, and
      in the same amount, except that Class A, Class B, and Class C shares can
      bear different transfer agent and distribution fees.


                                                                              23

NOTES TO FINANCIAL STATEMENTS 6/30/98                                (continued)
- --------------------------------------------------------------------------------

2.    Management Agreement

Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets.

PMC has agreed not to impose a portion of its management fee and to assume other
operating expenses of the Fund to the extent necessary to limit Class A expenses
to 1.00% of the average daily net assets attributable to Class A shares; the
portion of the Fund-wide expenses attributable to Class B and Class C shares
will be reduced only to the extent that such expenses are reduced for Class A
shares. PMC's agreement is voluntary and temporary and may be revised or
terminated at any time.

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At June 30, 1998, $18,225 was payable to PMC related to management
fees and certain other services.

3.    Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $16,298 in transfer agent fees payable to PSC at June 30, 1998.

4.    Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan, and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $39,128 in distribution fees payable to
PFD at June 30, 1998.

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

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within four years of purchase are subject to a
CDSC at declining rates beginning at 3.0%, based on the lower of cost or market
value of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to
PFD. For the six months ended June 30, 1998, CDSCs in the amount of $2,171 were
paid to PFD.

5.    Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended June 30, 1998,
the Fund's expenses were reduced by $2,285 under such arrangements.

6.    Line of Credit Facility

Effective April 14, 1998, the Fund, along with certain others in the Pioneer
Family of Funds (the "Funds"), collectively participate in a $50 million
committed, unsecured revolving line of credit facility. Borrowings are used
solely for temporary or emergency purposes. The Fund may borrow up to the lesser
of $50 million or the limits set by its prospectus for borrowings. Interest on
collective borrowings of up to $25 million is payable at the Federal Funds Rate
plus 3/8% on an annualized basis, or at the Federal Funds Rate plus 1/2% if the
borrowings exceed $25 million at any one time. The Funds pay an annual
commitment fee for this facility. The commitment fee is allocated among such
Funds based on their respective borrowing limits.

The average daily amount of borrowings outstanding during the period from April
14, 1998 through June 30, 1998 was $23,252. The average daily shares outstanding
during the period were 6,105,687, resulting in an average borrowing of less than
one cent per share. The related weighted average annualized interest rate for
the period was 5.91%, and the total interest expense on such borrowings was
$298.


                                                                              25

A simple way to move money from one Pioneer fund to another over a period of

LETTER FROM THE CHAIRMAN 12/31/97
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

I am pleased to present this report for Pioneer Intermediate Tax-Free Fund,
covering its fiscal year ended December 31, 1997. On behalf of the Fund's
investment team, I thank you for your interest and this opportunity to comment
briefly on today's investing environment.

Since October, investors have shown increasing demand for U.S. bonds, as the
world's stock markets have been exceptionally volatile. Asian markets plunged in
the face of severe instability in currencies and economic growth. Here in the
United States, the Dow Jones Industrial Average experienced - in the space of
two days - both its biggest one-day point drop and its biggest one-day point
gain. Although it recovered, its pace has since been unsteady. European markets
bounced around, shaken by the drop in Asia and then heartened by the speedy U.S.
rebound. Even Latin American markets were affected, mostly in a chain reaction
from nervous investors.

After consecutive quarters of robust growth in stocks, this fast-paced change
forced individuals and institutions to rethink their investment strategy. Money
has poured into the bond market, with demand spilling over into tax-free
markets. These positive conditions are driving prices up and yields down. Many
investors have moved away from stocks and into high-quality, U.S. fixed-income
securities - like those held by your Fund - to shelter their portfolio. We have
always believed it is important to allocate assets among both stocks and bonds,
and recent market conditions demonstrate this importance.

I encourage you to read on to learn more about your Fund. Please contact your
investment representative, or us at 1-800-225-6292, if you have questions about
Pioneer Intermediate Tax-Free Fund.

Respectfully,


/s/ John F. Cogan, Jr.

John F. Cogan, Jr.,
Chairman and President

Pioneer Intermediate Tax-Free Fund

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 12/31/97
- --------------------------------------------------------------------------------

Pioneer Intermediate Tax-Free Fund's fiscal year came to a close on December 31,
1997. We saw a variety of conditions in the bond market in 1997. Interest rates
rose early on then moved to historic lows when trouble overseas sparked a
tremendous year-end rally in taxable bonds. Happily, this positive momentum
spilled over into municipal bond markets. When all was said and done, the Fund
posted a solid return, both from price appreciation and paying steady income.

For this report, we offer a discussion with Kathleen D. McClaskey, portfolio
manager of Pioneer Intermediate Tax-Free Fund. She leads the investment team
responsible for handling day-to-day management of your portfolio, and has been
managing the Fund for 11 years.

Q:    How did the Fund perform over the past 12 months?

A:    Municipal bond prices were strong for much of the year. As measured by the
      Lehman Brothers Municipal Bond Index, munis returned 9.19% for the year,
      above the 7.16% average return generated by intermediate municipal debt
      funds followed by Lipper Analytical Services. (Lipper is an independent
      company that tracks fund performance.)

      Your Fund's total return of 6.87% for Class A Shares at net asset value
      was close to that of other funds. Of course, by design your Fund is more
      conservative than longer-term bond funds, and you should not expect it to
      match their performance when long-term interest rates fall. Importantly,
      at year-end your Fund offered a tax-free 30-day yield of 3.41%. This was
      quite an attractive rate - equal to a taxable yield of 5.65% for investors
      in the maximum 39.6% tax bracket. We are pleased to report these
      competitive returns, especially since they were achieved with a moderate
      amount of risk and without sacrificing quality.

Q:    What fundamental factors shaped the U.S. bond market this year?

A:    Early in the year, all eyes were fixed on the economy. We experienced
      substantial economic growth powered by low unemployment - a traditional
      harbinger of inflation. The Federal Reserve, after months of "hands-off"
      policing of the economy, increased the federal funds rate by 0.25
      percentage points to 5.50% on March 25. Bond prices fell both before and
      after the much anticipated Fed move.

      Although temporarily affected by the Fed's hike, municipal bonds benefited
      from several positive trends throughout 1997. Moderate demand for munis
      was matched with moderate supply, and with few new issues coming into the
      market, prices held fairly steady. Fears of a "flat tax" evaporated,
      restoring confidence in municipal bonds. Most importantly, both taxable
      and tax-free bond prices prospered as the economy resumed its "Goldilocks"
      condition - economic growth at a pace that was "not too hot, not too
      cold." Inflationary pressures cooled, and interest rates descended. These
      prime con ditions gave bond prices a boost and made a vital contribution
      to year-end performance.

Q:    How did global troubles affect U.S. bonds?

A:    In the fourth quarter, financial markets fell apart in Pacific Rim
      countries such as South Korea and Indonesia. The effects reached the
      United States, where stocks experienced - in the span of two October days
      - both their largest-ever point loss and gain. However, the effects were
      positive for fixed-income investments, including municipal bonds.
      Increased volatility in stocks caused many investors to allocate more
      assets to bonds. A "flight to quality" resulted as investors demanded
      historically "safer" investments, especially high-quality fixed-income
      securities. This mindset spilled over into the U.S. municipal bond market,
      and helped drive up prices of securities like those in your Fund.

Q:    With all these changes in 1997, how did you position the Fund?

A:    We kept the portfolio well diversified; it now has 63 holdings spread over
      33 states. We also focused on high-quality issues. At year-end, AAA-rated
      securities accounted for 36% of the portfolio, and AA securities were 46%.
      (Ratings are assigned by Standard & Poor's or Moody's Investor Services;
      AAA is the highest quality rating these agencies apply to debt issuers.)
      The average quality of Fund holdings remained a steady AA, as we expect it
      will for the foreseeable future.

      With interest rates at historic lows, a wave of refinancing is taking
      place and bonds with plump coupon rates are being "called" by their
      issuers. (When interest rates fall, issuers "call" existing debt, buying


                                                                               7

      it back from investors and replacing it with a new issue tied to lower
      interest rates.) In response, we searched diligently for other investment
      options. One effective strategy was to continue buying non-callable bonds
      throughout the year. These pay interest for the life of the bond, and if
      interest rates continue to decline, your Fund will benefit from a set
      income stream. This approach also slightly increased the Fund's effective
      average maturity. At year-end, average maturity was 8.89 years, up from
      8.06 years at the end of 1996. This is still solidly medium range and, we
      think, strikes a good balance between risk and reward.

      Our dedication to quality showed in our focus on insured bonds, now 19.7%
      of the portfolio. These securities give the Fund an extra modicum of price
      stability because third-party insurers guarantee that interest and
      principal payments will be made on time and in full, even if the issuer of
      the debt is unable to pay. Of course this guarantee applies to individual
      securities, not to the price or yield of Fund shares.

Q:    What's ahead for the Fund?

A:    We're still optimistic about municipal bonds. For one thing, demand is
      helping push prices higher. As more and more baby boomers approach
      retirement, we're likely to see them shift a larger percentage of assets
      into the historically lower-risk categories of fixed-income and tax-free
      investments. And even after the Taxpayer Relief Act of 1997, we think
      investors will want to protect their income and investments from taxes.

      Clearly, the effects of the Asian crisis are far reaching. They have
      certainly put a hold on any further interest rate intervention by the Fed,
      which we expect to continue its "wait and see attitude." The U.S. eco nomy
      continues to move forward at a steady pace, even with Asia's problems in
      the background. Inflation still appears to be contained. All of these are
      prime ingredients for continued low interest rates. In fact, we could see
      bond prices move even higher if rates continue to drop. But no matter
      which direction interest rates take, we will continue to focus on a
      portfolio of quality bonds with an overall intermediate maturity to help
      carry your Fund through 1998.

NOTES TO FINANCIAL STATEMENTS 12/31/97
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Intermediate Tax-Free Fund (the Fund) is a Massachusetts business trust
registered under the Investment Company Act of 1940 as a diversified, open-end
management investment company. The investment objective of the Fund is to seek a
high level of current income exempt from federal income taxes.

The Fund offers three classes of shares - Class A, Class B, and Class C shares.
Shares of Class A, Class B, and Class C each represent an interest in the same
portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidation, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B, and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:

A.    Security Valuation

      Security transactions are recorded on trade date. Securities are valued
      based on valuations furnished by independent pricing services that utilize
      matrix systems. These matrix systems reflect such factors as security
      prices, yields, maturities, and ratings and are supplemented by dealer and
      exchange quotations and fair market value information from other sources,
      as required. Market discount and premium are accreted or amortized daily
      on a straight-line basis. Original issue discount is accreted daily into
      interest income on a yield-to-maturity basis with a corresponding increase
      in the cost basis of the security. Interest income is recorded on the
      accrual basis. Temporary cash investments are valued at amortized cost.


22
<PAGE>

Pioneer Intermediate Tax-Free Fund

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

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

      Gains and losses on sales of investments are calculated on the identified
      cost method for both financial reporting and federal income tax purposes.
      It is the Fund's practice to first select for sale those securities that
      have the highest cost and also qualify for long-term capital gain or loss
      treatment for tax purposes.

B.    Federal Income Taxes

      It is the Fund's policy to comply with the requirements of the Internal
      Revenue Code applicable to regulated investment companies and to
      distribute all of its taxable income and net realized capital gains, if
      any, to its shareholders. Therefore, no federal tax provision is required.

      The characterization of distributions to shareholders for financial
      reporting purposes is determined in accordance with federal income tax
      rules. Therefore, the source of the Fund's distributions may be shown in
      the accompanying financial statements as either from or in excess of net
      investment income or net realized gain on investment transactions, or from
      paid-in capital, depending on the type of book/tax differences that may
      exist.

      At December 31, 1997, the Fund reclassified $11,460 from accumulated
      undistributed net investment income to accumulated undistributed net
      realized gain on investments. The reclassification has no impact on the
      net asset value of the Fund and is designed to present the Fund's capital
      accounts on a tax basis.

      In order to comply with federal income tax regulations, the Fund has
      des-ignated $608,190 as a capital gain dividend for the purposes of the
      dividend paid deduction. Of this amount, $90,367 and $517,823 are subject
      to the maximum 28% and 20% federal income tax rates, respectively.

      In order to comply with federal income tax regulations, the Fund has
      designated $2,952,468 as tax-exempt interest dividends. For purposes of
      the dividend exclusion, none of the distributions per share qualify for
      the exclusion.


                                                                              23

NOTES TO FINANCIAL STATEMENTS 12/31/97                               (continued)
- --------------------------------------------------------------------------------

C.    Fund Shares

      The Fund records sales and repurchases of its shares on trade date. Net
      losses, if any, as a result of cancellations are absorbed by Pioneer Funds
      Distributor, Inc. (PFD), the principal underwriter for the Fund and an
      indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $5,138 in
      underwriting commissions on the sale of the fund shares during the year
      ended December 31, 1997.

D.    Class Allocations

      Distribution fees are calculated based on the average daily net asset
      value attributable to Class A, Class B, and Class C shares of the Fund,
      respectively. Shareholders of each class share all expenses and fees paid
      to the transfer agent, Pioneering Services Corporation (PSC), for their
      services, which are allocated based on the number of accounts in each
      class and the ratable allocation of related out-of-pocket expense (see
      Note 3). Income, common expenses and realized and unrealized gains and
      losses are calculated at the Fund level and allocated daily to each class
      of shares based on the respective percentage of adjusted net assets at the
      beginning of the day. The Fund declares as daily dividends substantially
      all of its net investment income. All dividends are paid on a monthly
      basis. Short-term capital gain distributions, if any, may be declared with
      the daily dividends. Distributions to shareholders are recorded as of the
      ex-dividend date. Distributions paid by the Fund with respect to each
      class of shares are calculated in the same manner, at the same time, and
      in the same amount, except that Class A, Class B, and Class C shares can
      bear different transfer agent and distribution fees.

2.    Management Agreement

Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets.

PMC has agreed not to impose a portion of its management fee and to assume other
operating expenses of the Fund to the extent necessary to limit Class A expenses
to 1.00% of the average daily net assets attributable to Class A shares; the
portion of the Fund-wide expenses attributable to Class B and Class C shares
will be reduced only to the extent that such expenses are reduced for Class A
shares. PMC's agreement is voluntary and temporary and may be revised or
terminated at any time.

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

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At December 31, 1997, $25,667 was payable to PMC related to management
fees and certain other services.

3.    Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $7,965 in transfer agent fees payable to PSC at December 31, 1997.

4.    Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan, and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $42,694 in distribution fees payable to
PFD at December 31, 1997.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 3%, based on the lower of cost or market
value of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSC are paid to PFD.
For the year ended December 31, 1997, CDSCs in the amount of $4,065 were paid to
PFD.

5.    Expense Reductions

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the year ended December 31, 1997,
the Fund's expenses were reduced by $14,325 under such arrangements.


                                                                              25

management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Intermediate Tax-Free Fund as of December 31, 1997, the results of its
operations, the changes in its net assets and the financial highlights for the
periods presented, in conformity with generally accepted accounting principles.

PROGRAMS AND SERVICES FOR PIONEER SHAREOWNERS
- --------------------------------------------------------------------------------

Your investment professional can give you additional information on Pioneer's
programs and services. If you want to order literature on any of the following
items directly, simply call Pioneer at 1-8O0-225-6292.

FactFone(SM)

Our automated account information service, available to you 24 hours a day,
seven days a week. FactFone gives you a quick and easy way to check fund share
prices, yields, dividends and distributions, as well as information about your
own account. Simply call 1-800-225-4321. For specific account information, have
your 13-digit account number and four-digit personal identification number at
hand.

9O-Day Reinstatement Privilege (for Class A Shares)

Enables you to reinvest all or a portion of the money you redeem from your
Pioneer account - without paying a sales charge - within 90 days of your
redemption. You have the choice of investing in any Pioneer fund, as long as you
meet its minimum investment requirement.

Investomatic Plan

An easy and convenient way for you to invest on a regular basis. All you need to
do is authorize a set amount of money to be moved out of your bank account into
the Pioneer fund of your choice. Investomatic also allows you to change the
dollar amount, frequency and investment date right over the phone. By putting
aside affordable amounts of money regularly, you can build a long-term
investment - without sacrificing your current standard of living.

Payroll Investment Program (PIP)

Lets you invest in a Pioneer fund directly through your paycheck. All that's
involved is for your employer to fill out an authorization form allowing Pioneer
to deduct from participating employees' paychecks. You specify the dollar amount
you want to invest into the Pioneer fund(s) of your choice.

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

Automatic Exchange Program

A simple way to move money from one Pioneer fund to another over a period of
time. Just invest a lump sum in one fund, and select the other Pioneer funds you
wish to invest in. You choose the amounts and dates for Pioneer to sell shares
of your original fund and use the proceeds to buy shares of the funds you have
chosen. Over time, your investment will be shifted out of the original fund.
(Automatic Exchange is available for originating accounts with a balance of
$5,000 or more.)

Directed Dividends

Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distri butions are not eligible at this
time.)

Direct Deposit

Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.

Systematic Withdrawal Plan (SWP)

Lets you establish automatic withdrawals from your account at set intervals. You
decide the frequency and the day of the month you want. Pioneer will send the
proceeds by check to the address you designate, or electronically to your bank
account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available only for accounts with a value of $10,000 or
more.)

Pioneer Tax-Free Income Fund

LETTER FROM THE CHAIRMAN 6/30/98

Dear Shareowner,
- --------------------------------------------------------------------------------

While the Taxpayer Relief Act of 1997 provided lower rates on capital gains, it
did not ease the tax burden on investment income. As a result, municipal bonds
remain one of the few effective ways for investors to protect themselves from
taxes. We are happy to offer Pioneer Intermediate Tax-Free Fund as a choice for
conservative, tax-sensitive investors. The Fund's professional management and
diversified portfolio make tax-free investing affordable and accessible, an
important point since municipal bonds can be difficult for individuals to buy
and sell directly. Although municipal bonds did not keep pace with the snappy
gains posted by taxable U.S. government and corporate bonds over the past six
months, they generated solid returns and attractive after-tax dividends.

We have always recommended that investors diversify their portfolios among both
stocks and bonds, and recent market volatility has underscored this point. What
can you as an investor do? I encourage you to periodically review your financial
goals and strategy with your investment professional. It's a simple step to make
sure you will be better prepared to weather the inevitable swings in the market.

Please read on to learn more about how your Fund is being managed. If you have
questions about Pioneer Tax-Free Income Fund, please contact your investment
professional, or Pioneer at 1-800-225-6292.

Respectfully,

/s/ John F. Cogan, Jr.

The Lehman Brothers Municipal Bond Index is an unmanaged measure of
approximately 15,000 municipal bonds. Bonds in the Index have a minimum credit
rating of BBB, were part of at least a $50 million issuance made within the past
five years and have a maturity of at least two years. Index returns are
calculated monthly, assume reinvestment of dividends and, unlike Fund returns,
do not reflect any fees, expenses or sales charges. You cannot invest directly
in the Index.

Pioneer Tax-Free Income Fund

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 6/30/98
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

Pioneer  Tax-Free  Income  Fund closed the first half of its fiscal year on June
30, 1998. During that time,  favorable economic  conditions in the United States
and a "flight to quality" in the U.S. Treasury market pushed taxable bond prices
higher and  long-term  interest  rates to historic  lows.  Even so, an increased
supply of municipal  bonds  combined with weak demand,  hurt the  performance of
munis,  especially  when compared to taxable  bonds.  

Mark L. Winter has managed Pioneer Tax-Free Income Fund for the past 12 years,
leading the investment team responsible for the Fund's daily activities. The
following discussion with Mr. Winter details the investment environment and the
strategies that affected your Fund's performance, and provides his outlook for
the second half of 1998.

Q: How did the Fund perform in the first half of 1998?

A:  Pioneer  Tax-Free  Income Fund delivered  competitive  returns.  For the six
    months,  Class A Shares  returned  2.46%,  Class B Shares  2.16% and Class C
    Shares  2.08%,  all at net  asset  value.  In  comparison,  the 246  general
    municipal debt funds followed by Lipper  Analytical  Services returned 2.26%
    for  the  same  period.  (Returns  do not  reflect  sales  charges.)  Lipper
    Analytical  Services is an independent company that tracks fund performance.
    
    The Fund's Class A Shares also provided a tax-free  30-day yield of 3.84% on
    June 30. That translated  into an attractive  taxable-  equivalent  yield of
    6.35% for an investor in the 39.6% maximum federal tax bracket.

Q:  Did the situation in Asia affect U.S. interest rates and bonds?

A:  The uncertainty of the Asian crisis kept interest rates, and bond prices,
    within a narrow range for most of the period. It also sparked a "flight to
    quality." Generally, investors waited for new developments and evidence of
    the situation's effect on the U.S. economy. When the crisis worsened this
    spring, investors sought the safety and security

    of U.S. Treasuries. This demand again pushed up prices of taxable bonds and
    lowered interest rates.

    Asia's problems held down U.S. interest rates for another reason, too. Many
    investors were concerned that our strong economy eventually might stimulate
    inflation and lead the Federal Reserve to raise interest rates. But, because
    the United States and Asia are active trading partners, slowing Asian
    economies could lessen U.S. economic growth. That would ease inflationary
    pressures and reduce the Fed's impetus to change rates.

Q:  What was the environment like for municipal bonds over the past six months?

A:  Basically it was a case of supply and demand. The supply of municipal bonds
    increased dramatically during the first quarter of 1998, as many state and
    local governments took advantage of lower interest rates to refinance
    higher-cost bonds or to finance new projects. In fact, this period included
    the largest transaction ever to occur in the tax-exempt market - Long Island
    Power Authority's $6.5 billion issue. Ironically, all this good news for
    municipalities didn't help municipal bond investors much since the flood of
    supply kept prices from rising. In addition, the continuing economic
    problems in Asia increased the popularity of U.S. Treasury bonds,
    particularly among foreign investors. Municipal bond prices rose but not as
    fast or far as Treasurys.

    The yield on the benchmark 30-year U.S. Treasury fell from 5.92% on December
    31, 1997 to 5.63% on June 30. In comparison, the yield on the Lehman
    Brothers Municipal Bond Index - a good indicator of the municipal bond
    market - only fell from 4.70% on December 31 to 4.65% on June 30.

Q:  What strategies did you use to manage the Fund?

A:  We emphasized total return and income by adjusting the Fund's sensitivity to
    interest rate changes. We also maintained the Fund's high


                                                                               7

    standards of quality and focused on attractive relative value. As of June
    30, 54% of the Fund's holdings were insured AAA-rated bonds, translating
    into an average rating of "AA+." (Ratings apply to underlying securities,
    not Fund shares.) The portfolio remained well diversified with 178 holdings
    spread over 41 states.

    We increased total return potential by increasing the portfolio's duration
    from 6.44 years on December 31 to 7.70 years on June 30. Duration measures a
    Fund's sensitivity to changes in interest rates. Generally, an investment's
    price will change 1% for every 1% change in interest rates. Higher durations
    mean more potential for both price appreciation when interest rates fall and
    price declines when interest rates rise; shorter durations reduce interest
    rate sensitivity.

    We implemented this strategy by selling bonds with nearing "call dates" and
    reinvesting in bonds with 15 to 20 year maturities because "call" provisions
    relate to a predetermined date for an issuer to repurchase a bond from its
    holder. Often, this happens when interest rates decline so that an issuer
    can refinance the bonds at lower rates. Selling callable bonds improved the
    Fund's potential for both price appreciation and long-term income generation
    for several reasons. Bonds with longer maturities offer better potential for
    price appreciation when interest rates decline, and longer streams of
    predictable income.

Q:  What is your outlook for municipal bonds over the next six months?

A:  Over the near-term, we expect many of the trends that were positive for
    municipal bonds during the past six months to continue through the end of
    1998. We believe solid economic growth and minimal inflation in the United
    States can spur ongoing improvement in the financial health of
    municipalities. After the recent flood of offerings, we think issuers are
    taking a breather, which should give tax-exempt bond prices a lift. Looking
    out further, we expect Asia to have a powerful influence on interest rates.
    If there is a significant spillover into the U.S. economy, interest rates
    could remain stable or move moderately lower.

Pioneer Tax-Free Income Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/98
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Tax-Free Income Fund (the Fund) is a Delaware business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek a high level
of income exempt from federal income tax, consistent with preservation of
capital.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
The shares of Class A, Class B and Class C each represent an interest in the
same portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidations, except that each class of shares can
bear different transfer agent and distribution fees and has exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:

A. Security Valuation

   Security transactions are recorded on trade date. Securities are valued at
   prices supplied by independent pricing services, which consider such factors
   as Treasury spreads, yields, maturities and ratings, and valuations may be
   supplemented by dealers and other sources, as required. Market discount and
   premium are accreted or amortized daily on a straight-line basis. Original
   issue discount is accreted daily into interest income on a yield-to-maturity
   basis with a corresponding increase in the cost basis of the security.
   Interest income is recorded on the accrual basis. Temporary cash investments
   are valued at amortized cost.


26

<PAGE>

Pioneer Tax-Free Income Fund

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes. It
   is the Fund's practice to first select for sale those securities that have
   the highest cost and also qualify for long-term capital gain or loss
   treatment for tax purposes.


B. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareholders. Therefore, no federal income tax provision is required.

   The characterization of distributions to shareholders for financial reporting
   purposes is determined in accordance with federal income tax rules.
   Therefore, the source of the Fund's distributions may be shown in the
   accompanying financial statements as either from or in excess of net
   investment income or net realized gain on investment transactions, or from
   paid-in capital, depending on the type of book/tax differences that may
   exist.

C. Fund Shares

   The Fund records sales and repurchases of shares on trade date. Net losses,
   if any, as a result of cancellations, are absorbed by Pioneer Funds
   Distributor, Inc. (PFD), the principal underwriter for the Fund and an
   indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $25,068 in
   underwriting commissions on the sale of fund shares during the six months
   ended June 30, 1998.

D. Class Allocations

   Distribution fees are calculated based on the average daily net asset value
   attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Shareholders of each class share all expenses and fees paid to
   the transfer agent, Pioneering Services Corporation (PSC), for their
   services, which are allocated based on the number of accounts in each class
   and the ratable allocation of related out-of-pocket expense (see Note 3).
   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on the respective percentage of adjusted net assets at the beginning of
   the day.

                                                                              27

Pioneer Tax-Free Income Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 6/30/98                                (continued)
- --------------------------------------------------------------------------------

   The Fund declares as daily dividends substantially all of its net investment
   income. All dividends are paid on a monthly basis. Short-term capital gain
   distributions, if any, may be declared with the daily dividends.
   Distributions to shareholders are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner, at the same time, and in the same amount,
   except that Class A, Class B and Class C shares can bear different transfer
   agent and distribution fees.

2. Management Agreement

Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets up to $250 million; 0.48% of the next $50 million; and 0.45% of the
excess over $300 million. 

In addition, under the management agreement, certain
other services and costs, including accounting, regulatory reporting and
insurance premiums, are paid by the Fund. At June 30, 1998, $170,799 was payable
to PMC related to management fees and certain other services.

3. Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $84,106 in transfer agent fees payable to PSC at June 30, 1998.

4. Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance ser-

vices or distribution services with regard to Class B and Class C shares.
Included in due to affiliates is $254,992 in distribution fees payable to PFD at
June 30, 1998. 

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 4.0%, based on the lower of cost or market
value of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSCs are paid to
PFD. For the six months ended June 30, 1998, CDSCs in the amount of $6,843 were
paid to PFD.

5. Expense Offsets

The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the six months ended June 30, 1998,
the Fund's expenses were reduced by $1,629 under such arrangements.

6. Line of Credit Facility

Effective April 14, 1998, the Fund, along with certain others in the Pioneer
Family of Funds (the "Funds"), collectively participate in a $50 million
committed, unsecured revolving line of credit facility. Borrowings are used
solely for temporary or emergency purposes. The Fund may borrow up to the lesser
of $50 million or the limits set by its prospectus for borrowings. Interest on
collective borrowings of up to $25 million is payable at the Federal Funds Rate
plus 3/8% on an annualized basis, or at the Federal Funds Rate plus 1/2% if the
borrowings exceed $25 million at any one time. The Funds pay an annual
commitment fee for this facility. The commitment fee is allocated among such
Funds based on their respective borrowing limits. For the period ended June 30,
1998, the Fund had no borrowings under this agreement.


                                                                              29

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Shareholders and the Board of Trustees of 
Pioneer Tax-Free Income Fund:

We have audited the accompanying balance sheet of Pioneer Tax-Free Income Fund,
including the schedule of investments, as of June 30, 1998, and the related
statement of operations and the statements of changes in net assets for the
periods presented and financial highlights for the six months ended June 30,
1998 and for each of the four years ended December 31, 1997. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights for the year ended December 31, 1993, were audited by other auditors
whose report dated February 22, 1994 expressed an unqualified opinion.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of June
30, 1998 by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion. 

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Tax-Free Income Fund as of June 30, 1998, the results of its operations
and the changes in its net assets for the periods presented and financial
highlights for the six months ended June 30, 1998 and for each of the four years
ended December 31, 1997, in conformity with generally accepted accounting
principles.

9O-Day Reinstatement Privilege (for Class A Shares)

Pioneer account - without paying a sales charge - within 90 days of your
redemption. You have the choice of investing in any Pioneer fund, as long as you
meet its minimum investment requirement.

Investomatic Plan

An easy and convenient way for you to invest on a regular basis. All you need to
do is authorize a set amount of money to be moved out of your bank account into
the Pioneer fund of your choice. Investomatic also allows you to change the
dollar amount, frequency and investment date right over the phone. By putting
aside affordable amounts of money regularly, you can build a long-term
investment - without sacrificing your current standard of living.

Payroll Investment Program (PIP)

Lets you invest in a Pioneer fund directly through your paycheck. All that's
involved is for your employer to fill out an authorization form allowing Pioneer
to deduct from participating employees' paychecks. You specify the dollar amount
you want to invest into the Pioneer fund(s) of your choice. 

32
<PAGE>

Automatic Exchange Program 

A simple way to move money from one Pioneer fund to another over a
period of time. Just invest a lump sum in one fund, and select the other Pioneer
funds you wish to invest in. You choose the amounts and dates for Pioneer to
sell shares of your original fund and use the proceeds to buy shares of the
other funds you have chosen. Over time, your investment will be shifted out of
the original fund. (Automatic Exchange is available for originating accounts
with a balance of $5,000 or more.)

Directed Dividends

Lets you invest cash dividends from one Pioneer fund to an account in another
Pioneer fund with no sales charge or fee. Simply fill out the applicable
information on a Pioneer Account Options Form. (This program is available for
dividend payments only; capital gains distributions are not eligible at this
time.)

Direct Deposit

Lets you move money into your bank account using electronic funds transfer
(EFT). EFT moves your money faster than you would receive a check, eliminates
unnecessary paper and mail, and avoids lost checks. Simply fill out a Pioneer
Direct Deposit Form, giving your instructions.

Systematic Withdrawal Plan (SWP)

Lets you establish automatic withdrawals from your account at set intervals. You
decide the frequency and the day of the month you want. Pioneer will send the
proceeds by check to the address you designate, or electronically to your bank
account. You also can authorize Pioneer to make the redemptions payable to
someone else. (SWPs are available for accounts with a value of $10,000 or more.)

RETIREMENT PLANS FROM PIONEER
- --------------------------------------------------------------------------------

Pioneer has a long history of helping people work toward their retirement goals,
offering plans suited to the individual investor and businesses of all sizes.
For more information on Pioneer retirement plans, contact your investment
professional, or call Pioneer at 1-800-622-0176.

Individual Retirement Account (IRA)

An IRA is a tax-favored account that allows anyone under age 701/2 with earned
income to contribute up to $2,000 annually. Spouses may contribute up to $2,000
annually into a separate IRA, for a total of $4,000 per year for a married
couple. Earnings are tax-deferred, and contributions may be tax-deductible.

Roth IRA

The Roth IRA came about as part of the Taxpayer Relief Act of 1997 and is
available to investors in 1998. Contributions, up to $2,000 a year, are not
tax-deductible, but earnings are tax-free for qualified withdrawals.

401(k) Plan

The traditional 401(k) plan allows employees to make pre-tax contributions
through payroll deduction, up to $9,500 per year or 25% of pay, whichever is
less. Employers may contribute.

SIMPLE (Savings Incentive Match PLan for Employees)
401(k) or IRA Plan

Businesses with 100 or fewer eligible employees can establish either plan; both
resemble the traditional 401(k), but with less testing and lower administration
costs. Employees can make pre-tax contributions of up to $6,000 per year, and an
employer contribution is required.

Most retirement plan withdrawals must meet specific conditions to avoid
problems.

34
<PAGE>

403(b) Plan

Also known as a Tax-Sheltered Account (TSA), a 403(b) plan is available only to
employees of public schools, not-for-profit hospitals and other tax-exempt
organizations. A 403(b) plan lets employees set aside a portion of their salary,
before taxes, through payroll deduction.

Simplified Employee Pension Plan (SEP)

SEPs let self-employed people and small-business owners make tax-deductible
contributions of up to 15% of their income. Generally, employers must contribute
the same percentage of pay for themselves and any eligible employees;
contributions are made directly to employees' IRAs. SEPs are easy to administer
and can be an especially good choice for firms with few or no employees.

Profit Sharing Plan

Profit sharing plans offer companies considerable flexibility, allowing them to
decide each year whether a contribution will be made and how much, up to 15% of
each participant's pay. These plans can include provisions for loans and vesting
schedules.

Age-Weighted Profit Sharing Plan

Like traditional profit sharing plans, employer contributions are flexible, but
age-weighted plans allocate contributions based on both age and salary.
Age-weighted plans are designed for employers who want to maximize their own
contributions while keeping contributions to employees affordable.

Money Purchase Pension Plan (MPP)

Money purchase plans are similar to profit sharing plans, but allow for higher
annual contributions - up to 25% of pay. MPPs aren't as flexible as profit
sharing plans; a fixed percentage of pay must be contributed each year,
determined when the plan is established. Businesses often set up both MPPs and
profit sharing plans.

Most retirement plan withdrawals must meet specific conditions to avoid
problems.

LETTER FROM THE CHAIRMAN 12/31/97
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------

I am pleased to present this report for Pioneer America Income Trust, covering
its fiscal year ended December 31, 1997. On behalf of the Fund's investment
team, I thank you for your interest and this opportunity to comment briefly on
today's investing environment.

Since October, investors have shown increasing demand for U.S. bonds, as the
world's stock markets have been exceptionally volatile. Asian markets plunged in
the face of severe instability in currencies and economic growth. Here in the
United States, the Dow Jones Industrial Average experienced - in the space of
two days - both its biggest one-day point drop and its biggest one-day point
gain. Although it recovered, its pace has since been unsteady. European markets
bounced around, shaken by the drop in Asia and then heartened by the speedy U.S.
rebound. Even Latin American markets were affected, mostly in a chain reaction
from nervous investors.

After consecutive quarters of robust growth in stocks, this fast-paced change
forced individuals and institutions to rethink their investment strategy. Money
has poured into the bond market, driving prices up and yields down - to record
levels in the case of the 30-year U.S. Treasury bond. Many investors have moved
away from stocks and into high-quality U.S. fixed-income securities - like those
held by your Fund - to shelter their portfolio. We have always believed it is
important to allocate assets among both stocks and bonds, and recent market
conditions demonstrate this importance.

I encourage you to read on to learn more about your Fund. Please contact your
investment representative, or us at 1-800-225-6292, if you have questions about
Pioneer Tax-Free Income Fund.

Respectfully,


/s/ John F. Cogan, Jr.

John F. Cogan, Jr.,
Chairman and President

Pioneer Tax-Free Income Fund

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 12/31/97
- --------------------------------------------------------------------------------

Pioneer Tax-Free Income Fund's 22nd fiscal year came to a close on December 31,
1997. We saw a variety of conditions in 1997: rising interest rates early in the
year were followed by declining rates. Late in the year, trouble overseas
sparked a tremendous rally in U.S. government bonds, and this positive momentum
spilled over into municipal bond markets. When all was said and done, the Fund
posted a solid return, from both price appreciation and steady income.

For this report, we offer a discussion with Mark L. Winter, portfolio manager of
Pioneer Tax-Free Income Fund. He leads the investment team responsible for
handling day-to-day management of your portfolio, and has been managing the Fund
for 11 years.

  Q: How did the Fund perform over the past 12 months?

  A: Municipal bond prices were strong for much of the year. As measured by the
     Lehman Brothers Municipal Bond Index, munis returned 9.19% for the year,
     slightly above the 9.11% average total return generated by general
     municipal debt funds followed by Lipper Analytical Services. (Lipper is an
     independent company that tracks fund performance.)

     Your Fund's performance closely followed, with an 8.94% total return for
     Class A Shares at net asset value. Importantly, at year-end your Fund
     offered a tax-free 30-day yield of 3.94%. This was quite an attractive rate
     - equal to a taxable yield of 6.52% for investors in the maximum 39.6% tax
     bracket. We are pleased to report these competitive returns, especially
     since they were achieved without sacrificing quality or taking on more than
     a moderate degree of risk.

  Q: What fundamental factors shaped the U.S. bond market this year?

  A: Early in the year, all eyes were fixed on the economy. We experienced
     substantial economic growth powered by low unemployment and producers
     operating near full capacity - the traditional harbingers of inflation. The
     Federal Reserve, after months of "hands-off" policing of the economy,
     increased the federal funds rate by 0.25 percentage points to 5.50% on
     March 25. Bond prices fell both before and after the much anticipated Fed
     move.

     Although temporarily affected by the Fed's hike, municipal bonds benefited
     from several positive trends throughout 1997. Moderate demand for munis was
     matched with moderate supply, and with few new issues coming into the
     market, prices held fairly steady. Fears of a "flat tax" evaporated,
     restoring confidence in municipal bonds. Most importantly, both taxable and
     tax-free bond prices prospered as the economy resumed its "Goldilocks"
     condition - economic growth at a pace that was "not too hot, not too cold."
     Inflationary pressures cooled, and interest rates descended. These prime
     conditions gave bond prices a boost and made a vital contribution to
     year-end performance.

  Q: How did global troubles affect U.S. bonds?

  A: In the fourth quarter, financial markets fell apart in Pacific Rim
     countries such as South Korea and Indonesia. The effects reached the United
     States, where stocks experienced - in the span of two October days - both
     their largest point loss and gain. However, the effects were positive for
     fixed-income investments, including municipal bonds, as increased
     volatility in stock prices caused many investors to allocate more assets to
     bonds. A "flight to quality" resulted from the demand for historically
     "safer" investments, especially high-quality fixed-income securities. This
     mindset spilled over into the U.S. municipal bond market, and helped drive
     up prices of securities like those in your Fund.

  Q: With all these changes in 1997, how did you position the Fund?

  A: We kept the portfolio well diversified; it now has 170 holdings spread over
     37 states. We also focused on high-quality issues. At year-end, AAA-rated
     securities accounted for 51% of the portfolio, compared to 50% in December
     1996. (Ratings are assigned by Standard & Poor's or Moody's Investor
     Services; AAA is the highest quality rating these agencies apply to debt
     issuers.) The average quality of Fund holdings remained a steady AA, as we
     expect it will for the foreseeable future.


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 12/31/97                             (continued)
- --------------------------------------------------------------------------------

     We adjusted the maturity of Fund holdings to accommodate the changing
     interest rate environment. We increased the portfolio's average effective
     maturity in March to capture opportunities for appreciation created by
     falling interest rates. But by year-end, the portfolio's mix of long and
     short maturities provided an effective average maturity of 8.7 years, down
     from 12.6 years at the end of 1996. With interest rates now at historic
     lows, this more conservative risk profile should offer a level of
     protection if interest rates reverse direction and climb higher.

     Our dedication to quality showed in our focus on insured bonds, now 43% of
     the portfolio. These securities give the Fund an extra modicum of price
     stability because third-party insurers guarantee that interest and
     principal payments will be made on time and in full, even if the issuer of
     the debt is unable to pay. Of course this guarantee applies to individual
     securities, not to the price or yield of Fund shares.

  Q: What's ahead for the Fund?

  A: We're still optimistic about bonds. For one, demand is helping push prices
     higher. As more and more baby boomers approach retirement, we're likely to
     see them shift a larger percentage of assets into the historically
     lower-risk categories of fixed-income and tax-free investments. And even
     after the Taxpayer Relief Act of 1997, we think investors will want to
     protect income and investments from taxes.

     Clearly, the effects of the Asian crisis are far reaching. We now wait to
     see how deep these problems run. They have certainly put a hold on any
     further interest rate intervention by the Fed, which we expect to continue
     its "wait and see attitude." The U.S. economy continues to move forward at
     a steady pace, even with Asia's problems in the background. Inflation still
     appears to be contained. All of these factors are prime ingredients for
     continued low interest rates. In fact, we could see bond prices move even
     higher if rates continue to drop. But no matter which direction interest
     rates take, we will continue to focus on quality to help carry your Fund
     forward and help provide a solid total return while generating current
     income exempt from federal taxes.

Pioneer Tax-Free Income Fund

- --------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 12/31/97
- --------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer Tax-Free Income Fund (the Fund) is a Delaware business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek a high level
of income exempt from federal income tax, consistent with preservation of
capital.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
The shares of Class A, Class B and Class C each represent an interest in the
same portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidations, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:

A. Security Valuation

   Security transactions are recorded on trade date. Securities are valued based
   on valuations furnished by independent pricing services that utilize matrix
   systems. These matrix systems reflect such factors as security prices,
   yields, maturities, and ratings and are supplemented by dealer and exchange
   quotations and fair market value information from other sources, as required.
   Market discount and premium are accreted or amortized daily on a
   straight-line basis. Original issue discount is accreted daily into interest
   income on a yield-to-maturity basis with a corresponding increase in the cost
   basis of the security. Interest income is recorded on the accrual basis.
   Temporary cash investments are valued at amortized cost.


26
<PAGE>

Pioneer Tax-Free Income Fund

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

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

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes. It
   is the Fund's practice to first select for sale those securities that have
   the highest cost and also qualify for long-term capital gain or loss
   treatment for tax purposes.

B. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareholders. Therefore, no federal tax provision is required. 

   The characterization of distributions to shareholders for financial reporting
   purposes is determined in accordance with federal income tax rules.
   Therefore, the source of the Fund's distributions may be shown in the
   accompanying financial statements as either from or in excess of net
   investment income or net realized gain on investment transactions, or from
   paid-in capital, depending on the type of book/tax differences that may
   exist.

   At December 31, 1997, the Fund reclassified $59,758 and $113,545 from
   accumulated undistributed net investment income and paid-in capital,
   respectively, to accumulated net realized loss on investments. The
   reclassification has no impact on the net asset value of the Fund and is
   designed to present the Fund's capital accounts on a tax basis.

   In order to comply with federal income tax regulations, the Fund has
   designated $5,067,940 as a capital gain dividend for the purposes of the
   dividend paid deduction. Of this amount, $1,659,676 and $3,408,264 are
   subject to the maximum 28% and 20% federal income tax rates, respectively.

   In order to comply with federal income tax regulations, the Fund has
   designated $20,799,469 as tax-exempt interest dividends. For pur-poses of the
   dividends exclusion, none of the distributions per share qualify for the
   exclusion.

C. Fund Shares

   The Fund records sales and repurchases of shares on trade date. Net losses,
   if any, as a result of cancellations, are absorbed by Pioneer Funds
   Distributor, Inc. (PFD), the principal underwriter for the Fund and an
   indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $50,526 in
   underwriting commissions on the sale of fund shares 


                                                                              27

NOTES TO FINANCIAL STATEMENTS 12/31/97 (continued)
- --------------------------------------------------------------------------------

   during the year ended December 31, 1997.

D. Class Allocations

   Distribution fees are calculated based on the average daily net asset value
   attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Shareholders of each class share all expenses and fees paid to
   the transfer agent, Pioneering Services Corporation (PSC), for their
   services, which are allocated based on the number of accounts in each class
   and the ratable allocation of related out-of-pocket expense (see Note 3).
   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on the respective percentage of adjusted net assets at the beginning of
   the day. 

   The Fund declares as daily dividends substantially all of its net investment
   income. All dividends are paid on a monthly basis. Short-term capital gain
   distributions, if any, may be declared with the daily dividends.
   Distributions to shareholders are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner, at the same time, and in the same amount,
   except that Class A, Class B and Class C shares can bear different transfer
   agent and distribution fees.

2. Management Agreement

Pioneering Management Corporation (PMC), the Fund's investment adviser, manages
the Fund's portfolio and is a wholly owned subsidiary of PGI. Management fees
are calculated daily at the annual rate of 0.50% of the Fund's average daily net
assets up to $250 million; 0.48% of the next $50 million; and 0.45% of the
excess over $300 million. 

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At December 31, 1997, $186,896 was payable to PMC related to
management fees and certain other services.

3. Transfer Agent

PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $39,034 in transfer agent fees payable to PSC at December 31,
1997.

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

4. Distribution Plans

The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $267,174 in distribution fees payable
to PFD at December 31, 1997. 

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 4.0%, based on the lower of cost or market
value of shares being redeemed. Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%. Proceeds from the CDSC are paid to PFD.
For the year ended December 31, 1997, CDSCs in the amount of $24,904 were paid
to PFD.

5. Expense Reductions

The Fund has entered into certain expense offset arrangements result-ing in a
reduction in the Fund's total expenses. For the year ended December 31, 1997,
the Fund's expenses were reduced by $82,267 under such arrangements.


                                                                              29

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Shareholders and the Board of Trustees of Pioneer Tax-Free Income Fund:

We have audited the accompanying balance sheet of Pioneer Tax-Free Income Fund,
including the schedule of investments, as of December 31, 1997, and the related
statement of operations, and the statements of changes in net assets for the
periods presented and financial highlights for each of the four years ended
December 31, 1997. These financial statements and financial highlights are the
respon- si bility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the year ended December 31, 1993 were
audited by other auditors whose report dated February 22, 1994 expressed an
unqualified opinion.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Tax-Free Income Fund as of December 31, 1997, the results of its
operations and the changes in its net assets for the periods presented and
financial highlights for each of the four years ended December 31, 1997, in
conformity with generally accepted accounting principles.

  Automatic Exchange Program

  A simple way to move money from one Pioneer fund to another over a period of
  time. Just invest a lump sum in one fund, and select the other Pioneer funds
  you wish to invest in. You choose the amounts and dates for Pioneer to sell
  shares of your original fund and use the proceeds to buy shares of the other

  original fund. (Automatic Exchange is available for originating accounts with
  a balance of $5,000 or more.)

  Directed Dividends

RETIREMENT PROGRAMS FROM PIONEER
- --------------------------------------------------------------------------------

  Pioneer has a long history of helping people work toward their retirement
  goals, offering plans suited to the individual investor and businesses of all
  sizes. For more information on Pioneer retirement plans, contact your
  investment professional, or call Pioneer at
  1-800-622-0176.

  Individual Retirement Account (IRA)

  An IRA is a tax-favored account that allows anyone under age 701/2 with earned
  income to contribute up to $2,000 annually. Spouses may contribute up to
  $2,000 annually into a separate IRA, for a total of $4,000 per year for a
  married couple. Earnings are tax-deferred, and contributions may be
  tax-deductible.

  Roth IRA

  The Roth IRA came about as part of the Taxpayer Relief Act of 1997 and is
  available to investors in 1998. Contributions, up to $2,000 a year, are not
  tax-deductible, but earnings are tax-free for qualified withdrawals.

  401(k) Plan

  The traditional 401(k) plan allows employees to make pre-tax contributions
  through payroll deduction, up to $9,500 per year or 25% of pay, whichever is
  less. Employers may contribute.

  SIMPLE (Savings Incentive Match PLan for Employees)
  401(k) or IRA Plan

  Businesses with 100 or fewer eligible employees can establish either plan;
  both resemble the traditional 401(k), but with less testing and lower
  administration costs. Employees can make pre-tax contributions of up to $6,000
  per year, and an employer contribution is required.

Most retirement plan withdrawals must meet specific conditions to avoid
penalties.

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

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

  403(b) Plan

  Also known as a Tax-Sheltered Account (TSA), a 403(b) plan is available
  only to employees of public schools, not-for-profit hospitals
  and other tax-exempt organizations. A 403(b) plan lets employees set aside a
  portion of their salary, before taxes, through payroll deduction.

  Simplified Employee Pension Plan (SEP)

  SEPs let self-employed people and small-business owners make tax-deductible
  contributions of up to 15% of their income. Generally, employers must
  contribute the same percentage of pay for themselves and any eligible
  employees; contributions are made directly to employees' IRAs. SEPs are easy
  to administer and can be an especially good choice for firms with few or no
  employees.

  Profit Sharing Plan

  Profit sharing plans offer companies considerable flexibility, allowing them
  to decide each year whether a contribution will be made and how much, up to
  15% of each participant's pay. These plans can include provisions for loans
  and vesting schedules.

  Age-Weighted Profit Sharing Plan

  Like traditional profit sharing plans, employer contributions are flexible,
  but age-weighted plans allocate contributions based on both age and salary.
  Age-weighted plans are designed for employers who want to maximize their own
  contributions while keeping contributions to employees affordable.

  Money Purchase Pension Plan (MPP)

  Money purchase plans are similar to profit sharing plans, but allow for higher
  annual contributions -- up to 25% of pay. MPPs aren't as flexible as profit
  sharing plans; a fixed percentage of pay must be contributed each year,
  determined when the plan is established. Businesses often set up both MPPs and
  profit sharing plans.

Most retirement plan withdrawals must meet specific conditions to avoid
penalties.


                                                                              35

PIONEER TAX-FREE INCOME FUND
NOTES TO PRO FORMA FINANCIAL STATEMENTS 12/31/97
(UNAUDITED)

1.  GENERAL
The accompanying pro forma financial statements are presented to show the effect
of the proposed acquisition of Pioneer Intermediate Tax-Free Fund by Pioneer
Tax-Free Income Fund, as if such acquisition had taken place on January 1, 1997.

Under the terms of an Agreement and Plan of Reorganization, the combination
of Pioneer Tax-Free Income Fund and Pioneer Intermediate Tax-Free Fund will be
treated as a tax-free business combination and accordingly will be accounted for
by a method of accounting for tax-free mergers of investment companies
(sometimes referred to as the pooling without restatement method). The
acquisition would be accomplished by an acquisition of the net assets of Pioneer
Intermediate Tax-Free Fund in exchange for shares of Pioneer Tax-Free Income
Fund at net asset value. The statement of assets and liabilities and the related
statement of operations of Pioneer Tax-Free Income Fund and Pioneer Intermediate
Tax-Free Fund have been combined as of and for the year ended December 31, 1997.

The following notes refer to the accompanying pro forma financial statements as
if the above mentioned merger of Pioneer Tax-Free Income Fund and Pioneer
Intermediate Tax-Free Fund had taken place as of January 1, 1997.

2. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Pioneer Tax-Free Income Fund (the Fund) is a Delaware business trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek as high a
level of current income exempt from federal income taxes as possible consistent
with the preservation of capital.

The Fund offers three classes of shares - Class A, Class B and Class C shares.
The shares of Class A, Class B and Class C each represent an interest in the
same portfolio of investments of the Fund and have equal rights to voting,
redemptions, dividends and liquidations, except that each class of shares can
bear different transfer agent and distribution fees and have exclusive voting
rights with respect to the distribution plans that have been adopted by Class A,
Class B and Class C shareholders, respectively.

The Fund's financial statements have been prepared in conformity with generally
accepted accounting principles that require the management of the Fund to, among
other things, make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates. The following is a summary of significant accounting policies
consistently followed by the Fund, which are in conformity with those generally
accepted in the investment company industry:


<PAGE>


PIONEER TAX-FREE INCOME FUND
NOTES TO PRO FORMA FINANCIAL STATEMENTS 12/31/97 (CONTINUED)
(UNAUDITED)


A.  SECURITY VALUATION
     Security transactions are recorded on trade date. Securities are valued at
     prices supplied by independent pricing services, which consider such
     factors as Treasury spreads, yields, maturities and ratings, and valuations
     may be supplemented by dealers and other sources, as required. Market
     discount and premium are accreted or amortized daily on a straight-line
     basis. Original issue discount is accreted daily into interest income on a
     yield-to-maturity basis with a corresponding increase in the cost basis of
     the security. Interest income is recorded on the accrual basis.
     Temporary cash investments are valued at amortized cost.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.
     It is the Fund's practice to first select for sale those securities that
     have the highest cost and also qualify for long-term capital gain or loss
     treatment for tax purposes.

B.  FEDERAL INCOME TAXES
     It is the Fund's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareholders. Therefore, no federal tax provision is required.

C.  FUND SHARES
     The Fund records sales and repurchases of shares on trade date. Net losses,
     if any, as a result of cancellations, are absorbed by Pioneer Funds
     Distributor, Inc. (PFD), the principal underwriter for the Fund and an
     indirect subsidiary of The Pioneer Group, Inc. (PGI). PFD earned $55,664 in
     underwriting commissions on the sale of fund shares during the year ended
     December 31, 1997.

D.  CLASS ALLOCATIONS
     Distribution fees are calculated based on the average daily net asset value
     attributable to Class A, Class B and Class C shares of the Fund,
     respectively. Shareholders of each class share all expenses and fees paid
     to the transfer agent, Pioneering Services Corporation (PSC), for their
     services, which are allocated based on the number of accounts in each class
     and the ratable allocation of related out-of-pocket expense (see Note 3).
     Income, common expenses and realized and unrealized gains and losses are
     calculated at the Fund level and allocated daily to each class of shares
     based on the respective percentage of adjusted net assets at the beginning
     of the day.

     The Fund declares as daily dividends substantially all of its net
     investment income. All dividends are paid on a monthly basis. Short-term
     capital gain distributions, if any, may be declared with the daily
     dividends. Distributions to shareholders are recorded as of the ex-dividend
     date. Distributions paid by the Fund with respect to each class of shares
     are calculated in the same manner, at the same time, and in the


<PAGE>


PIONEER TAX-FREE INCOME FUND
NOTES TO PRO FORMA FINANCIAL STATEMENTS 12/31/97 (CONTINUED)
(UNAUDITED)


     same amount, except that Class A, Class B and Class C shares can bear
     different transfer agent and distribution fees.

3.    PRO FORMA ADJUSTMENTS
The accompanying pro forma financial statements reflect changes in fund shares
as if the merger had taken place on January 1, 1997. Adjustments have been made
to expenses for duplicated services that would not have been incurred if the
merger took place on January 1, 1997. In addition, adjustments have been made to
expenses to reflect management fees and management fees waived as if the merger
had taken place on January 1, 1997.

4.  MANAGEMENT AGREEMENT
Pioneer Investment Management, Inc. (PIM), the Fund's investment adviser,
manages the Fund's portfolio and is a wholly owned subsidiary of PGI. Management
fees are calculated daily at the annual rate of 0.50% of the Fund's average
daily net assets up to $250 million; 0.48% of the next $50 million; and 0.45% of
the excess over $300 million.

In addition, under the management agreement, certain other services and costs,
including accounting, regulatory reporting and insurance premiums, are paid by
the Fund. At December 31, 1997, $143,164 was payable to PIM related to
management fees and certain other services.

5.  TRANSFER AGENT
PSC, a wholly owned subsidiary of PGI, provides substantially all transfer agent
and shareholder services to the Fund at negotiated rates. Included in due to
affiliates is $46,999 in transfer agent fees payable to PSC at December 31,
1997.

6.  DISTRIBUTION PLANS
The Fund adopted a Plan of Distribution for each class of shares (Class A Plan,
Class B Plan and Class C Plan) in accordance with Rule 12b-1 of the Investment
Company Act of 1940. Pursuant to the Class A Plan, the Fund pays PFD a service
fee of up to 0.25% of the Fund's average daily net assets in reimbursement of
its actual expenditures to finance activities primarily intended to result in
the sale of Class A shares. Pursuant to the Class B Plan and the Class C Plan,
the Fund pays PFD 1.00% of the average daily net assets attributable to each
class of shares. The fee consists of a 0.25% service fee and a 0.75%
distribution fee paid as compensation for personal services and/or account
maintenance services or distribution services with regard to Class B and Class C
shares. Included in due to affiliates is $309,868 in distribution fees payable
to PFD at December 31, 1997.

In addition, redemptions of each class of shares may be subject to a contingent
deferred sales charge (CDSC). A CDSC of 1.00% may be imposed on redemptions of
certain net asset value purchases of Class A shares within one year of purchase.
Class B shares that are redeemed within six years of purchase are subject to a
CDSC at declining rates beginning at 4.0%, based on the lower of cost or market
value of shares being redeemed.


<PAGE>


PIONEER TAX-FREE INCOME FUND
NOTES TO PRO FORMA FINANCIAL STATEMENTS 12/31/97 (CONTINUED)
(UNAUDITED)


Redemptions of Class C shares within one year of purchase are subject to a
CDSC of 1.00%. Proceeds from the CDSCs are paid to PFD. For the year ended
December 31, 1997, CDSCs in the amount of $28,969 were paid to PFD.

7.  EXPENSE OFFSETS
The Fund has entered into certain expense offset arrangements resulting in a
reduction in the Fund's total expenses. For the year ended December 31, 1997,
the Fund's expenses were reduced by $96,592 under such arrangements.

                               OTHER INFORMATION


Item 15.  Indemnification

Except for the Agreement and Declaration of Trust (the "Declaration"),
dated June 16, 1994, establishing the Registrant as a business trust under
Delaware law, there is no contract, arrangement or statute under which any
Trustee, officer, underwriter or affiliated person of the Registrant is insured
or indemnified. The Declaration provides that no Trustee or officer will be
indemnified against any liability to which the Registrant would otherwise be
subject by reason of or for willful misfeasance, bad faith, gross negligence or
reckless disregard of such person's duties.

Insofar as indemnification for liability arising under the Securities Act
of 1933, as amended (the "1933 Act"), may be available to Trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission (the "SEC") such indemnification is against public
policy as expressed in the 1933 Act and is, therefore, unenforceable. In the
event that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a Trustee, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such Trustee, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 1933 Act
and will be governed by the final adjudication of such issue.

                      AGREEMENT AND PLAN OF REORGANIZATION

         THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made as
of this ___ day of __________, 1999, by and between Pioneer Intermediate Tax-
Free Fund, a Massachusetts business trust with its principal place of business
at 60 State Street, Boston, Massachusetts 02109 (the "Acquired Fund"), and
Pioneer Tax-Free Income Fund (the "Acquiring Fund"), a Delaware business trust
with its principal place of business at 60 State Street, Boston, Massachusetts
02109.

         This Agreement is intended to be and is adopted as a plan of
reorganization within the meaning of Section 368(a)(1) of the United States
Internal Revenue Code of 1986, as amended (the "Code"). The reorganization will
consist of the transfer of all of the assets of the Acquired Fund to the
Acquiring Fund in exchange for the issuance of Class A, Class B and Class C
shares of beneficial interest of the Acquiring Fund (the "Acquiring Fund
Shares") to the Acquired Fund and the assumption by the Acquiring Fund of the
liabilities of the Acquired Fund, followed by the distribution by the Acquired
Fund, on or promptly after the Closing Date hereinafter referred to, of the
Acquiring Fund Shares to the shareholders of the Acquired Fund in liquidation
and termination of the Acquired Fund as provided herein, all upon the terms and
conditions hereinafter set forth in this Agreement.

         In consideration of the premises of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ACQUIRING FUND
     SHARES AND LIQUIDATION OF THE ACQUIRED FUND

     1.1 The Acquired Fund will transfer all of its assets (consisting, without
limitation, of portfolio securities and instruments, dividends and interest
receivables, cash and other assets), as set forth in the statement of assets and
liabilities referred to in paragraph 7.2 hereof (the "Statement of Assets and
Liabilities"), to the Acquiring Fund free and clear of all liens and
encumbrances, except as otherwise provided herein in exchange for (i) the
assumption by the Acquiring Fund of all known and unknown liabilities of the
Acquired Fund, including the liabilities set forth in the Statement of Assets
and Liabilities, which shall be assigned and transferred to and assumed by the
Acquiring Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund,
for distribution PRO RATA by the Acquired Fund to its shareholders in proportion
to their respective ownership of Class A, Class B and/or Class C shares of
beneficial interest of the Acquired Fund, as of the close of business on the
closing date (the "Closing Date"), of a number of Acquiring Fund Shares having
an aggregate net asset value equal to the value of the assets, less such
liabilities (herein referred to as the "net value of the assets"), of the
Acquired Fund so transferred,


<PAGE>


assumed, assigned and delivered, all determined as provided in paragraph 2
and as of a date and time as specified therein. Such transactions shall take
place at the closing provided for in paragraph 3.1 hereof (the "Closing"). All
computations shall be provided by Brown Brothers Harriman & Co. (the
"Custodian"), as custodian for the Acquiring Fund and for the Acquired Fund and
shall be recomputed by Arthur Andersen LLP, independent auditors of the
Acquiring Fund. The determination of the Custodian, as recomputed by said
auditors, shall be conclusive and binding on all parties in interest.

     1.2 The Acquired Fund has provided the Acquiring Fund with a list of the
current securities holdings of the Acquired Fund as of the date of execution of
this Agreement. The Acquired Fund reserves the right to sell any of these
securities (except to the extent sales may be limited by representations made in
connection with issuance of the tax opinion described in paragraph 8.7 hereof)
but will not, without the prior approval of the Acquiring Fund, acquire any
additional securities other than securities of the type in which the Acquiring
Fund is permitted to invest.

     1.3 Each of the Acquiring Fund and the Acquired Fund shall bear its own
expenses in connection with the transactions contemplated by this Agreement.

     1.4 On or as soon after the Closing Date as is conveniently practicable
(the "Liquidation Date"), the Acquired Fund will liquidate and distribute PRO
RATA to shareholders of record ("the Acquired Fund shareholders"), determined as
of the close of regular trading on the New York Stock Exchange on the last day
such Exchange is open for unrestricted trading immediately preceding the Closing
Date (the "Valuation Date"), the Acquiring Fund Shares received by the Acquired
Fund pursuant to paragraph 1.1. Such liquidation and distribution will be
accomplished by the transfer of the Acquiring Fund Shares then credited to the
account of the Acquired Fund on the books of the Acquiring Fund, to open
accounts on the share records of the Acquiring Fund in the names of the Acquired
Fund shareholders and representing the respective PRO RATA number of Acquiring
Fund Shares due such shareholders. Acquired Fund shareholders who own Class A
shares of the Acquired Fund will receive Class A Acquiring Fund Shares, Acquired
Fund shareholders who own Class B shares of the Acquired Fund will receive Class
B Acquiring Fund Shares and Acquired Fund shareholders who own Class C shares of
the Acquired Fund will receive Class C Acquiring Fund Shares. The Acquiring Fund
will not issue share certificates representing Acquiring Fund Shares unless a
shareholder specifically requests the Acquiring Fund Shares in certificated form
and, if applicable, in exchange for outstanding certificates representing
Acquired Fund shares, as described in paragraph 1.5.

     1.5 The Acquiring Fund shall record the net asset value of all outstanding
Acquired Fund certificated shares in its books and records as of the Closing
Date, in accordance with paragraph 2.2, and daily thereafter, in accordance with
the Acquiring


                                      -2-


<PAGE>


Fund's procedures for determining net asset value per share. The Acquiring
Fund will honor certificates representing Acquired Fund shares at their net
asset value as determined on the books and records of the Acquiring Fund, and
subject to the Acquiring Fund's normal requirements for redeeming or
transferring shares evidenced by certificates. Acquired Fund shareholders need
not surrender such certificates or deliver affidavits with respect to lost
certificates after the Closing. Any Acquired Fund certificate which remains
outstanding on the Closing Date shall be deemed to be evidence of ownership of
the same class of shares of beneficial interest of the Acquiring Fund.

     1.6 Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than the registered holder of the Acquiring Fund Shares on the books
of the Acquired Fund as of that time shall, as a condition of such issuance and
transfer, be paid by the person to whom such Acquiring Fund Shares are to be
issued and transferred.

     1.7 The Acquired Fund shall file an application (on Form N-8F or such other
form deemed appropriate by the Securities and Exchange Commission (the
"Commission")) pursuant to Section 8(f) of the Investment Company Act of 1940,
as amended (the "1940 Act"), as soon as practicable following the Liquidation
Date, and the existence of the Acquired Fund shall be terminated in accordance
with Massachusetts law as promptly as practicable thereafter.

2.   VALUATION

     2.1 The net asset values of the Class A, Class B and Class C Acquiring Fund
Shares and the net value of the assets and liabilities of the Acquired Fund
attributable to its Class A, Class B and Class C shares to be transferred shall,
in each case, be determined as of the close of the New York Stock Exchange on
the Valuation Date. The net asset value per share of Acquiring Fund Shares shall
be computed by the Custodian in the manner set forth in the Agreement and
Declaration of Trust or By-Laws of the Acquiring Fund and then-current
prospectus and statement of additional information of the Acquiring Fund and
shall be computed to not fewer than four decimal places. The net value of the
assets of the Acquired Fund to be transferred shall be computed by the Custodian
by calculating the value of the assets attributable to each class of shares
transferred by the Acquired Fund and by subtracting therefrom the amount of the
liabilities attributable to each class of shares to be assigned and transferred
to and assumed by the Acquiring Fund on the Closing Date, said assets and
liabilities to be valued in the manner set forth in the Acquired Fund's most
recent prospectus and statement of additional information.

     2.2 The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Fund's
assets shall be determined by dividing the value of the Acquired Fund assets
attributable to


                                      -3-


<PAGE>


a class, less the liabilities attributable to that class assumed by the
Acquiring Fund, by the Acquiring Fund's net asset value per share of the
same class, all as determined in accordance with paragraph 2.1.

     2.3 All computations of value shall be made by the Custodian in accordance
with its regular practice as pricing agent for the Acquiring Fund.

3.   CLOSING AND CLOSING DATE

     3.1 The Closing Date shall be as of ____________, 1999, or as of such other
date on or before ____________, 1999 as the parties may agree in writing. The
Closing shall be held at 5:00 p.m., Boston time, at the offices of the Acquiring
Fund, 60 State Street, Boston, Massachusetts 02109, or at such other time and/or
place as the parties may agree in writing.

     3.2 Portfolio securities that are not held in book-entry form in the name
of the Custodian as record holder for the Acquired Fund shall be presented by
the Acquired Fund to the Custodian for examination no later than five business
days preceding the Valuation Date. Portfolio securities which are not held in
book-entry form shall be delivered by the Acquired Fund to the Custodian for the
account of the Acquiring Fund on the Closing Date, duly endorsed in proper form
for transfer, in such condition as to constitute good delivery thereof in
accordance with the custom of brokers, and shall be accompanied by all necessary
federal and state stock transfer stamps or a check for the appropriate purchase
price thereof. Portfolio securities held of record by the Custodian in
book-entry form on behalf of the Acquired Fund shall be delivered to the
Acquiring Fund by the Custodian by recording the transfer of ownership thereof
on its records. The cash delivered shall be in the form of currency or by the
Custodian crediting the Acquiring Fund's account maintained with the Custodian
with immediately available funds.

     3.3 In the event that on the proposed Valuation Date (a) the New York Stock
Exchange shall be closed to trading or trading thereon shall be restricted, or
(b) trading or the reporting of trading on said Exchange or elsewhere shall be
disrupted so that accurate appraisal of the value of the net assets of the
Acquiring Fund or the Acquired Fund is impracticable, the Closing Date shall be
postponed until the first business day after the day when trading shall have
been fully resumed and reporting shall have been restored; provided that if
trading shall not be fully resumed and reporting restored on or before
________________, 1999, this Agreement may be terminated by the Acquiring Fund
or the Acquired Fund upon the giving of written notice to the other party.


     3.4 The Acquired Fund shall deliver at the Closing a list of the names,
addresses, federal taxpayer identification numbers and backup withholding and


                                      -4-


<PAGE>


nonresident alien withholding status of Acquired Fund shareholders and the
number and percentage ownership of outstanding shares of each class of shares of
beneficial interest of the Acquired Fund owned by each such shareholder, all as
of the close of business on the Valuation Date, certified by its Treasurer,
Secretary or other authorized officer (the "Shareholder List"). The Acquiring
Fund shall issue and deliver to the Acquired Fund a confirmation evidencing the
Acquiring Fund Shares to be credited on the Liquidation Date, or provide
evidence satisfactory to the Acquired Fund that such Acquiring Fund Shares have
been credited to the Acquired Fund's account on the books of the Acquiring Fund.
At the Closing each party shall deliver to the other such bills of sale, checks,
assignments, certificates, receipts or other documents as such other party or
its counsel may reasonably request.

4.   REPRESENTATIONS AND WARRANTIES

     4.1 The Acquired Fund represents and warrants to the Acquiring Fund as

         Massachusetts and has the power to own all of its properties and assets
         and, subject to approval by the shareholders of the Acquired Fund, to
         perform its obligations under this Agreement. The Acquired Fund is not
         required to qualify to do business in any jurisdiction in which it is
         not so qualified or where failure to qualify would not subject it to
         any material liability or disability. The Acquired Fund has all
         necessary federal, state and local authorizations to own all of its
         properties and assets and to carry on its business as now being

         registration with the Commission as an investment company under the
         1940 Act is in full force and effect;

(c)      The Acquired Fund is not, and the execution, delivery and performance
         of this Agreement by the Acquired Fund will not result, in violation of

         other undertaking to which the Acquired Fund is a party or by which the
         Acquired Fund is bound;

(d)      The Acquired Fund has no material contracts or other commitments (other

         investigation of or before any court or governmental body is currently
         pending or threatened as to the Acquired Fund or any of its properties
         or assets. The Acquired Fund knows of no facts which might form the
         basis for the institution of such proceedings, and the Acquired Fund is
         not a party to or subject to the provisions of any order, decree or
         judgment of any court or governmental body which materially and
         adversely affects its business or its ability to consummate the
         transactions herein contemplated;

(f)      The statement of assets and liabilities, including the schedule of
         portfolio investments, of the Acquired Fund as of December 31, 1998 and

         statements of changes in net assets for the years ended December 31,
         1998 and 1997 (audited by Arthur Andersen LLP, independent public
         accountants) (copies of which have been furnished to the Acquiring
         Fund) present fairly in all material respects the financial position of
         the Acquired Fund as of December 31, 1998 and the results of its
         operations and changes in net assets for the respective stated periods
         in accordance with generally accepted accounting principles
         consistently applied, and there were no known actual or contingent
         liabilities of the Acquired Fund as of the respective dates thereof not
         disclosed therein;

         business, or any incurrence by the Acquired Fund of indebtedness
         maturing more than one year from the date such indebtedness was
         incurred, except as otherwise disclosed to and accepted by the
         Acquiring Fund;

(h)      At the date hereof and by the Closing Date, all federal, state and
         other tax returns and reports, including information returns and payee
         statements, of the Acquired Fund required by law to have been filed or
         furnished by such dates shall have been filed or furnished, and all
         federal, state and other taxes, interest and penalties shall have been
         paid so far as due, or provision shall have been made for the payment
         thereof, and to the best of the Acquired Fund's knowledge no such
         return is currently under audit and no assessment has been asserted
         with respect to such returns or reports;

(i)      The Acquired Fund has elected to be treated as a regulated investment
         company for federal income tax purposes, has qualified as such for


                                      -6-


<PAGE>


         each taxable year of its operation and will qualify as such as of the
         Closing Date with respect to its final taxable year ending on the
         Closing Date;

(j)      The authorized capital of the Acquired Fund consists of an unlimited
         number of shares of beneficial interest, no par value. All issued and
         outstanding shares of beneficial interest of the Acquired Fund are, and
         at the Closing Date will be, duly and validly issued and outstanding,
         fully paid and nonassessable. All of the issued and outstanding shares
         of beneficial interest of the Acquired Fund will, at the time of
         Closing, be held by the persons and in the amounts set forth in the
         Shareholder List. The Acquired Fund does not have outstanding any
         options, warrants or other rights to subscribe for or purchase any of
         its shares of beneficial interest, nor is there outstanding any
         security convertible into any of its shares of beneficial interest;

(k)      At the Closing Date, the Acquired Fund will have good and marketable
         title to the assets to be transferred to the Acquiring Fund pursuant to
         paragraph 1.1, and full right, power and authority to sell, assign,

Pioneer Tax-Free Income Fund

Boston, Massachusetts  02109

Ladies and Gentlemen:

         Pioneer Tax-Free Income Fund (the "Trust") was established as a
Nebraska Corporation on January 19, 1968 and reorganized as a Delaware business
trust under an Agreement and Declaration of Trust dated, June 30, 1994, as
amended from time to time (as so amended, the "Declaration of Trust"). The
beneficial interests thereunder are represented by transferable shares of
beneficial interest, no par value.

         The Trustees have the powers set forth in the Declaration of Trust,
subject to the terms, provisions and conditions therein provided. Pursuant to
Article V, Section 5.1 of the Declaration of Trust, the number of shares of
beneficial interest authorized to be issued under the Declaration of Trust is
unlimited and the Trustees are authorized to divide the shares into one or more
series of shares and one or more classes thereof as they deem necessary or
desirable. Pursuant to Article V, Section 5.4 of the Declaration of Trust, the
Trustees are empowered in their discretion to issue shares of any series for
such amount and type of consideration, including cash or property, and on such
terms as the Trustees may deem best (or for no consideration if pursuant to a
share dividend or split-up), all without action or approval of the shareholders.
As of the date of this opinion, the Trustees have divided the shares of the
Trust into four classes, designated as Class A, Class B, Class C and Class Y.

         The Trustees have voted to authorize the officers of the Trust to enter
into an Agreement and Plan of Reorganization between the Trust and Pioneer
Intermediate Tax-Free Fund (the "Agreement and Plan of Reorganization"), and to
determine the appropriate number of shares to be registered, to register with
the Securities and Exchange Commission, and to issue and sell to the public,
such shares.

         We have examined the Declaration of Trust and By-Laws, each as amended
from time to time, of the Trust, a draft of the Agreement and Plan of
Reorganization, resolutions of the Board of Trustees relating to the
authorization of the Agreement and Plan of Reorganization and the authorization
and issuance of shares of beneficial interest of the Trust, and such other
documents as we have deemed necessary or

appropriate for the purposes of this opinion, including, but not limited
to, originals, or copies certified or otherwise identified to our satisfaction,
of such documents, Trust records and other instruments. In our examination of
the above documents, we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals and the conformity to
original documents of all documents submitted to us as certified of photostatic
copies.

         Any reference to "our knowledge", to any matter "known to us", "coming
to our attention" or "of which we are aware" or any variation of any of the
foregoing shall mean the conscious awareness of the attorneys in this firm who
have rendered substantive attention to the Plan and Agreement of Reorganization
and the transactions contemplated thereby, of the existence or absence of any
facts which would contradict the opinions set forth below. We have not
undertaken any independent investigation to determine the existence or absence
of such facts, and no inference as to our knowledge of the existence or absence
of such facts should be drawn from the fact of our representation of the Trust.
Without limiting the foregoing, we have not examined any dockets or records of
any court, administrative tribunal or other similar entity, or any electronic or
computer databases, in connection with our opinions expressed below.

         Our opinions below are qualified to the extent that they may be subject
to or affected by (i) applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance or transfer, moratorium or similar laws affecting the
rights and remedies of creditors generally, (ii) statutory or decisional law
concerning recourse by creditors to security in the absence of notice or hearing
and (iii) duties and standards imposed on creditors and parties to contracts,
including, without limitation, requirements of good faith, reasonableness and
fair dealing. Further, we do not express any opinion as to (i) the availability
of the remedy of specific performance or any other equitable remedy upon breach
of any provision of any agreement whether applied by a court of law or equity,
(ii) the successful assertion of any equitable defense, or (iii) the right of
any party to enforce the indemnification or contribution provisions of any
agreement.

         In rendering the opinion below, insofar as it relates to the good
standing and valid existence of the Trust, we have relied solely on certificates
of the Secretary of State of the State Of Delaware, dated as of a recent date,
and such opinion is limited accordingly and is rendered as of the respective
dates of such certificates.

         This opinion is limited to the Delaware Business Trust Act, and we
express no opinion with respect to the laws of any other jurisdiction or to any
other laws of the State of Delaware. Further, we express no opinion as to
compliance with any state or federal securities laws, including the securities
laws of the State of Delaware.

         Our opinion below, as it relates to the non-assessability of the shares
of the Trust, is qualified to the extent that any shareholder is, was or may
become a named Trustee of the Trust. It is also qualified to the extent that,
pursuant to Section 2 of Article VIII of the Declaration of Trust, the Trustees
have the power to cause shareholders, or shareholders of a particular series, to
pay certain custodian, transfer, servicing or similar agent charges by setting
off the same against declared but unpaid dividends or by reducing share
ownership (or by both means).

         Assuming satisfaction with all conditions set forth in the draft
Agreement and Plan of Reorganization between the Trust and Pioneer Intermediate
Tax-Free Fund and the valid execution and delivery of such Agreement by the
parties thereto, we are of the opinion that all necessary Trust action precedent
to the issuance of the shares of beneficial interest of the Trust to be issued
pursuant to the Trust's Registration Statement on Form N-14 has been duly taken,
and that all such shares, when issued in accordance with the terms of the
Agreement and Plan of Reorganization, will be legally and validly issued, fully
paid and non-assessable by the Trust, subject to compliance with the Securities
Act of 1933, as amended, the Investment Company Act of 1940, as amended, and the
applicable state laws regulating the sale of securities.

         We are opining only as to the specific legal issues expressly set forth
herein, and no opinion should be inferred as to any other matters. We are
opining on the date hereof as to the law in effect on the date hereof, and we
disclaim any obligation to advise you of any change in any of these sources of
law or subsequent legal or factual developments which might affect any matters
or opinions set forth herein.

         This opinion is furnished to you solely for your use and may not be
quoted to or relied upon by any other person or entity or used for any other
purpose, without our prior written consent.

         We consent to your filing this opinion with the Securities and Exchange
Commission as an exhibit to any amendments to the Trust's registration statement
with the Commission. Except as provided in this paragraph, this opinion may not
be relied upon by, or filed with, any other parties or for any other purpose.

                                            Very truly yours,

Dear Members of the Boards of Trustees:

         You have requested our opinion regarding certain federal income tax
consequences described below of the acquisition by Pioneer Tax-Free Income Fund
("Acquiring Fund"), a business trust organized under the laws of the State of

Fund"), a business trust organized under the laws of The Commonwealth of
Massachusetts, in exchange solely for (i) the assumption by Acquiring Fund of
all of the liabilities of Acquired Fund and (ii) the issuance of Class A, Class
B and Class C voting shares of beneficial interest of Acquiring Fund (the
"Acquiring Fund Shares") to Acquired Fund, followed by the distribution by
Acquired Fund, in liquidation of Acquired Fund, of the Acquiring Fund Shares to

foregoing together constituting the "reorganization" or the "transaction").

         In rendering this opinion, we have examined and relied upon the facts
stated and representations made in (i) the prospectus for Acquiring Fund, dated

Shareholders Scheduled for March , 1999 and the accompanying proxy statement and
prospectus relating to the transaction dated January , 1999 (the "Proxy
Statement"), (vi) the Agreement and Plan of Reorganization, made as of
_______________, 1999, between Acquiring Fund and Acquired Fund (the
"Agreement"), (vii) the representation letters on behalf of Acquiring Fund and
Acquired Fund referred to below and (viii) such other documents as we deemed
appropriate.

         In our examination of documents, we have assumed the authenticity of
original documents, the accuracy of copies, the genuineness of signatures, and
the legal capacity of signatories. We have assumed that all parties to the
Agreement have acted and will act in accordance with the terms of the Agreement
and all other documents relating to the transaction and that the transaction
will be consummated pursuant to the terms and conditions set forth in the
Agreement without the waiver or modification of any such terms and conditions.
Furthermore, we have assumed that all representations contained in the
Agreement, as well as those representations contained in the representation
letters referred to below are, on the date hereof, true and complete in all
material respects, and that any representation made in any of the documents
referred to herein "to the best of the knowledge and belief" (or similar
qualification) of any person or party is correct without such qualification. We
have not attempted to verify independently such representations, but in the
course of our representation, nothing has come to our attention that would cause
us to question the accuracy thereof.

         The conclusions expressed herein represent our judgment regarding the
proper treatment of certain aspects of the transaction affecting Acquiring Fund,
Acquired Fund and the shareholders of Acquired Fund on the basis of our analysis
of the Internal Revenue Code of 1986, as amended (the "Code"), case law,
Treasury regulations and the rulings and other pronouncements of the Internal
Revenue Service (the "Service") which exist at the time this opinion is
rendered. Such authorities are subject to prospective or retroactive change, and
we do not undertake any responsibility to advise you of any such change. Our
opinion represents our best judgment regarding how a court would decide if
presented with the issues addressed herein and is not binding upon the Service
or any court. Moreover, our opinion does not provide any assurance that a
position taken in reliance on such opinion will not be challenged by the Service
and does not constitute any representation or warranty that such position, if so
challenged, will not be rejected by a court.

         This opinion addresses only the specific United States federal income
tax consequences of the transaction set forth below, and does not address any
other federal, state, local, or foreign income, estate, gift, transfer, sales,
or other tax consequences that may result from the transaction or any other
transaction.

                                      FACTS

         We understand that the facts relating to the transaction are as
described hereinafter.

         Acquiring Fund is a business trust established as a Nebraska
corporation in 1968 (referred to herein as Acquiring Fund's predecessor) and
reorganized as a business trust under the laws of the State of Delaware in a
transaction qualifying as a reorganization under Section 368(a)(1)(F) of the
Code on June 30, 1994. Acquiring Fund is registered as an open-end investment
company under the Investment Company Act of 1940, as amended (the "1940 Act").
Acquiring Fund and its predecessor have been operating as an investment company
since the inception of business in 1968.

         The investment objective of Acquiring Fund is to seek as high a level
of income exempt from regular federal income tax as possible, consistent with
preservation of capital. Acquiring Fund seeks to achieve this objective by
investing in a diversified portfolio of obligations issued by or on behalf of
states, counties and municipalities of the United States ("U.S.") and their
authorities and political subdivisions, the interest on which is excluded from
gross income for federal income tax purposes.

         Acquired Fund is a business trust established under the laws of The
Commonwealth of Massachusetts in 1986 and is registered as an open-end
investment company under the 1940 Act. Acquired Fund has been operating as an
investment company since the inception of business in 1986.

         The investment objective of Acquired Fund is to provide as high a level
of current income exempt from federal income taxes from a high-quality portfolio
of municipal bonds as is consistent with prudent investment risk. Acquired Fund
seeks to achieve this objective by investing, under normal conditions, at least
80% of its portfolio in bonds, notes and other debt instruments issued by or on
behalf of states, territories and possessions of the U.S. and the District of
Columbia and their political subdivisions, agencies or instrumentalities, the
interest on which is exempt from federal income tax.

         The steps comprising the reorganization, as set forth in the Agreement,
are as follows:



<PAGE>


         (i) Acquired Fund will transfer to Acquiring Fund all of its assets
(consisting, without limitation, of portfolio securities and instruments,
dividend and interest receivables, cash and other assets). In exchange for the
assets transferred to


<PAGE>


Boards of Trustees

it, Acquiring Fund will (A) assume all of the liabilities of Acquired Fund
(comprising all of its known and unknown liabilities and referred to hereinafter
as the "Acquired Fund Liabilities") and (B) issue Acquiring Fund Shares to
Acquired Fund that have an aggregate net asset value equal to the value of the
assets transferred to Acquiring Fund by Acquired Fund, less the Acquired Fund
Liabilities assumed by Acquiring Fund.

         (ii) Promptly after the transfer of its assets to Acquiring Fund,
Acquired Fund will distribute in liquidation the Acquiring Fund Shares it
receives in the exchange to Acquired Fund shareholders PRO RATA in exchange for
their surrender of their shares of beneficial interest of Acquired Fund
("Acquired Fund Shares"). In these exchanges, holders of Acquired Fund Shares
designated as Class A ("Class A Acquired Fund Shares") will receive Acquiring
Fund Shares designated as Class A ("Class A Acquiring Fund Shares"), holders of
Acquired Fund Shares designated as Class B ("Class B Acquired Fund Shares") will
receive Acquiring Fund Shares designated as Class B ("Class B Acquiring Fund
Shares"), and holders of Acquired Fund Shares designated as Class C ("Class C
Acquired Fund Shares") will receive Acquiring Fund Shares designated as Class C
("Class C Acquiring Fund Shares").

         (iii) After such exchanges, liquidation and distribution, the existence
of Acquired Fund will be promptly terminated in accordance with Massachusetts
law.

         The Agreement and the transactions contemplated thereby were approved
by the Board of Trustees of Acquiring Fund at a meeting of the Board of Trustees
held on December 1, 1998. Acquiring Fund shareholders are not required and were
not asked to approve the transaction. The Agreement and the transactions
contemplated thereby were approved by the Board of Trustees of Acquired Fund at
a meeting held on December 1, 1998, subject to the approval of Acquired Fund
shareholders. Acquired Fund shareholders approved the transaction at a meeting
held on _______________, 1999.

         Massachusetts law does not provide dissenters' rights for Acquired Fund
shareholders in the transaction. Additionally, it is the position of the
Division of Investment Management of the Securities and Exchange Commission that
appraisal rights, in contexts such as the reorganization, are inconsistent with
Rule 22c-1 under the 1940 Act and are therefore preempted and invalidated by
such rule. Consequently, Acquired Fund shareholders will not have dissenters' or
appraisal rights in the transaction.

         Our opinions set forth below are subject to the following factual
assumptions being true and correct (including statements relating to future
actions and facts represented to be to the best knowledge of management, whether
or not known).

Boards of Trustees
Pioneer Intermediate Tax-Free Fund

Authorized representatives of Acquiring Fund and Acquired Fund have
represented to us by letters of even date herewith that the following
assumptions are true and correct:

         (a) Neither Acquiring Fund nor any person treated as related to
Acquiring Fund under Treasury Regulation Section 1.368-1(e)(3) has any plan or
intention to redeem or otherwise reacquire any of the Acquiring Fund Shares
received by shareholders of Acquired Fund in the transaction except in the
ordinary course of Acquiring Fund's business in connection with its legal
obligation under Section 22(e) of the 1940 Act as a registered open-end
investment company to redeem its own shares (which obligation is not in
connection with, modified in connection with, or in any way related to the
transaction).

         (b) After the transaction, Acquiring Fund will continue the historic
business of Acquired Fund and will use all of the assets acquired from Acquired
Fund, which are Acquired Fund's historic business assets, I.E., assets not
acquired as part of or in contemplation of the transaction, in the ordinary
course of a business.

         (c) Acquiring Fund has no plan or intention to sell or otherwise
dispose of any assets of Acquired Fund acquired in the transaction, except for
dispositions made in the ordinary course of its business (I.E., dispositions
resulting from investment decisions made after the reorganization on the basis
of investment considerations independent of the reorganization) or to maintain
its qualification as a regulated investment company under Subchapter M of the
Code.

         (d) The shareholders of Acquiring Fund and the shareholders of Acquired
Fund will bear their respective expenses, if any, in connection with the
transaction.

         (e) Acquiring Fund and Acquired Fund will each bear its own expenses
incurred in connection with the transaction. Any liabilities of Acquired Fund
attributable to such expenses that remain unpaid on the closing date of the
transaction and are assumed by Acquiring Fund in the transaction are
attributable to Acquired Fund's expenses that are solely and directly related to
the transaction in accordance with the guidelines established in Rev. Rul.
73-54, 1973-1 C.B. 187.

         (f) There is no indebtedness between Acquiring Fund and Acquired Fund.

         (g) Acquired Fund has elected to be treated as a regulated investment
company under Subchapter M of the Code, has qualified as a regulated investment
company for each taxable year since inception, and qualifies as such for its
taxable year ending on the date of the transaction.


<PAGE>


Boards of Trustees
Pioneer Intermediate Tax-Free Fund
Pioneer Tax-Free Income Fund
________________, 1998

         (h) Acquiring Fund's predecessor elected to be treated as a regulated
investment company under Subchapter M of the Code. Acquired Fund and its
predecessor have qualified as a regulated investment company for each taxable
year since inception, and Acquiring Fund qualifies as such as of the date of the
transaction.

         (i) Neither Acquiring Fund nor Acquired Fund is under the jurisdiction
of a court in a Title 11 or similar case within the meaning of Section
368(a)(3)(A) of the Code.

         (j) Acquiring Fund does not own and has never owned, directly or
indirectly, any shares of Acquired Fund.

         (k) Acquiring Fund will not pay cash in lieu of fractional shares in
connection with the transaction.

         (l) As of the date of the transaction, the fair market value of the
Acquiring Fund Shares issued to Acquired Fund in exchange for the assets of
Acquired Fund is approximately equal to the fair market value of the assets of
Acquired Fund received by Acquiring Fund, minus the Acquired Fund Liabilities
assumed by Acquiring Fund. Acquiring Fund will not furnish any consideration in
connection with the acquisition of Acquired Fund's assets other than the
assumption of these Acquired Fund Liabilities and the issuance of these
Acquiring Fund Shares.

         (m) Acquired Fund shareholders will not be in control (within the
meaning of Sections 368(a)(2)(H)(i) and 304(c) of the Code, which provide that
control means the ownership of shares possessing at least 50% of the total
combined voting power of all classes of shares that are entitled to vote or at
least 50% of the total value of shares of all classes) of Acquiring Fund after
the transaction.

         (n) The principal business purposes of the transaction are to combine
the assets of Acquiring Fund and Acquired Fund in order to benefit from lower
expenses, including expense reductions due to economies of scale relating to the
costs of accounting, legal, transfer agency, insurance, custodial, and
administrative services, to eliminate the difficulty experienced by Acquired
Fund in attracting assets that results from competition with Acquiring Fund, to
benefit from Acquiring Fund's broader investment policy with respect to
permitted maturities and anticipated better performance, and to increase
diversification.

         (o) As of the date of the transaction, the fair market value of the
Class A Acquiring Fund Shares received by each shareholder that holds Class A
Acquired Fund Shares is approximately equal to the fair market value of the
Class A Acquired


<PAGE>


Boards of Trustees
Pioneer Intermediate Tax-Free Fund
Pioneer Tax-Free Income Fund
________________, 1998
Page 7


Fund Shares surrendered by such shareholder, the fair market value of the
Class B Acquiring Fund Shares received by each shareholder that holds Class B
Acquired Fund Shares is approximately equal to the fair market value of the
Class B Acquired Fund Shares surrendered by such shareholder, and the fair
market value of the Class C Acquiring Fund Shares received by each shareholder
that holds Class C Acquired Fund Shares is approximately equal to the fair
market value of the Class C Acquired Fund Shares surrendered by such
shareholder. No property other than Acquiring Fund Shares will be distributed to
shareholders of Acquired Fund in exchange for their Acquired Fund Shares, nor
will any such shareholder receive cash or other property as part of the
transaction.

         (p) There is no plan or intention on the part of any shareholder of
Acquired Fund that owns beneficially 5% or more of the Acquired Fund Shares and,
to the best knowledge of management of Acquired Fund, there is no plan or
intention on the part of the remaining shareholders of Acquired Fund, in
connection with the transaction, to engage in any transaction with Acquired
Fund, Acquiring Fund, or any person treated as related to Acquired Fund or
Acquiring Fund under the standards made applicable by Treasury Regulation
Section 1.368-1(e)(1)(i) involving the sale, redemption, exchange, transfer,
pledge, or other disposition resulting in a direct or indirect transfer of the
risks of ownership (a "Sale") of any of the Acquired Fund Shares or any of the
Acquiring Fund Shares to be received in the transaction that, considering all
Sales, would reduce the aggregate ownership of the Acquiring Fund Shares by
former Acquired Fund shareholders to a number of shares having a value, as of
the date of the transaction, of less than fifty percent (50%) of the value of
all of the formerly outstanding Acquired Fund Shares as of the same date. All
Sales involving shares of Acquired Fund and Acquiring Fund held by Acquired Fund
shareholders that have occurred or will occur in connection with the transaction
are taken into account for purposes of this representation. No such Sale that is
in connection with the transaction has, to the best knowledge of the management
of Acquired Fund, occurred on or prior to the date of the transaction.

         (q) Acquired Fund assets transferred to Acquiring Fund comprise at
least ninety percent (90%) of the fair market value of the net assets and at
least seventy percent (70%) of the fair market value of the gross assets held by
Acquired Fund immediately prior to the transaction. For purposes of this
representation, amounts used by Acquired Fund to pay its outstanding
liabilities, including reorganization expenses, and all redemptions and
distributions (except for redemptions in the ordinary course of business upon
demand of a shareholder that Acquired Fund is required to make as an open-end
investment company pursuant to Section 22(e) of the 1940 Act and regular, normal
dividends, which dividends include any final distribution of previously
undistributed investment company taxable income and net capital gain for
Acquired Fund's final taxable year ending on the date of the


<PAGE>


Boards of Trustees

transaction) made by Acquired Fund immediately preceding the transaction
are taken into account as assets of Acquired Fund held immediately prior to the
transaction.

         (r) The Acquired Fund Liabilities assumed by Acquiring Fund plus the
liabilities, if any, to which the transferred assets are subject were incurred
by Acquired Fund in the ordinary course of its business or are expenses of the
transaction.

         (s) The fair market value of the Acquired Fund assets transferred to
Acquiring Fund equals or exceeds the sum of the Acquired Fund Liabilities
assumed by Acquiring Fund and the amount of liabilities, if any, to which the
transferred assets are subject.

         (t) Acquired Fund does not pay compensation to any
shareholder-employee.

                                     OPINION

         On the basis of and subject to the foregoing and in reliance upon the
representations described above, we are of the opinion that:

         (a) The acquisition by Acquiring Fund of all of the assets of Acquired
Fund solely in exchange for the issuance of Acquiring Fund Shares to Acquired
Fund and the assumption of all of the Acquired Fund Liabilities by Acquiring
Fund, followed by the distribution by Acquired Fund, in liquidation of Acquired
Fund, of Acquiring Fund Shares to Acquired Fund shareholders in exchange for
their Acquired Fund Shares and the termination of Acquired Fund, will constitute
a "reorganization" within the meaning of Section 368(a)(1)(C) of the Code.
Acquiring Fund and Acquired Fund will each be "a party to a reorganization"
within the meaning of Section 368(b) of the Code.

         (b) No gain or loss will be recognized by Acquired Fund upon (i) the
transfer of all of its assets to Acquiring Fund solely in exchange for the
issuance of Acquiring Fund Shares to Acquired Fund and the assumption of all of
the Acquired Fund Liabilities by Acquiring Fund and (ii) the distribution by
Acquired Fund of such Acquiring Fund Shares to the shareholders of Acquired Fund
(Sections 361(a) and 361(c) of the Code).

         (c) No gain or loss will be recognized by Acquiring Fund upon the
receipt of the assets of Acquired Fund solely in exchange for the issuance of
Acquiring Fund Shares to Acquired Fund and the assumption of all of the Acquired
Fund Liabilities by Acquiring Fund (Section 1032(a) of the Code).

to the Funds or its shareholders by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties or by reason of its reckless
disregard of its obligations and duties under this Agreement.
