          to a Pioneer Fund in exchange for the same class of shares of your

          of shares of your fund on the closing date of the reorganization. The
          Pioneer Fund also will assume all of your fund's liabilities. Your
          fund will then be dissolved.

                                 INTRODUCTION


     This combined proxy statement/prospectus, dated August 11, 2006 (the "Proxy
Statement/Prospectus"), is being furnished to shareholders of the Pioneer Funds
in connection with the solicitation by the Board of Trustees (the "Board" or
the "Trustees") of the Pioneer Funds of proxies to be used at a joint special
meeting of the shareholders of the Pioneer Funds to be held at the offices of
Wilmer Cutler Pickering Hale and Dorr LLP, 26th Floor, Boston, Massachusetts on
October 17, 2006, at 2:00 p.m., Eastern Time. The Proxy Statement/  Prospectus
is being mailed to shareholders of the Pioneer Funds on or about August 11,
2006.


     The Proxy Statement/Prospectus contains information you should know before
voting on the proposed Agreement and Plan of Reorganization that provides for
the Reorganization of your fund into a corresponding Pioneer Fund (each, a
"Reorganization"). Please read the Proxy Statement/Prospectus carefully,
including Exhibit A and Exhibit B, because they are a part of this Proxy
Statement/Prospectus and contain details that are not in the summary.

     The following table indicates (a) the corresponding Pioneer Fund shares
that shareholders would receive if the Agreement and Plan of Reorganization is
approved, (b) which shareholders may vote on each proposal, and (c) what page
of this Proxy Statement/Prospectus the discussion regarding each proposal
begins. On each proposal, all shareholders of a Pioneer Fund, regardless of the
class of shares held, will vote together as a single class. Although each
Reorganization is similar in structure, you should read carefully the specific
discussion regarding your fund's Reorganization.

How Each Reorganization Will Work

     o  Your fund will transfer all of its assets to a corresponding Pioneer
        Fund. The Pioneer Fund will assume your fund's liabilities.

     o  Shares of the corresponding Pioneer Fund will be distributed to your
        fund's shareholders in proportion to their holdings of the applicable
        class of shares of your fund on the closing date of the Reorganization
        (the "Closing Date"). These shares will be distributed to shareholders
        in proportion to the relative net asset value of their share holdings on
        the Closing Date. On the Closing Date, each shareholder will hold shares
        of the corresponding Pioneer Fund with the same aggregate net asset
        value as their holdings of the applicable class of shares of your fund
        immediately prior to the Reorganization.


                                       2


     o  Your fund will be dissolved after the Closing Date.

     o  The Reorganizations will not result in income, gain or loss being
        recognized for federal income tax purposes by any of the Pioneer Funds
        or the shareholders of the Pioneer Funds.


     o  In recommending each of the Reorganizations, the Board of Trustees of
        each Pioneer Fund, including all of the Trustees who are not
        "interested" persons (as defined in the Investment Company Act of 1940,
        as amended (the "1940 Act")) of the Pioneer Funds, Pioneer Investment
        Management, Inc., the Pioneer Funds' investment adviser ("Pioneer") or
        Pioneer Funds Distributor, Inc., the Pioneer Funds' principal
        underwriter and distributor ("PFD") (the "Independent Trustees") have
        determined that the Reorganization is in the best interest of each
        Pioneer Fund and will not dilute the interests of shareholders of each
        Pioneer Fund. The Trustees have made this determination based on factors
        that are discussed below and in greater detail under each proposal.



Why Your Fund's Trustees Recommend the Reorganization

     The Trustees believe that reorganizing your fund into a similarly managed
Pioneer Fund offers you potential benefits. These potential benefits and
considerations include:

     o  The opportunity to be part of a combined Pioneer Fund with greater
        assets that may be better positioned in the market to further increase
        asset size and achieve economies of scale. Economies of scale have
        potential benefits to the combined fund in two ways. First, a larger
        fund, which trades in larger blocks of securities, will be able to hold
        larger positions in individual securities and, consequently, have an
        enhanced ability to achieve better net prices on securities trades. In
        addition, each Pioneer Fund incurs substantial operating costs for
        insurance, accounting, legal, and custodial services. The combination of
        the Pioneer Funds resulting from the Reorganization may spread fixed
        expenses over a larger asset base, potentially contributing to a lower
        expense ratio in the long term than your fund would achieve separately.

     o  The transaction will qualify as a tax free reorganization under Section
        368(a) of the Internal Revenue Code of 1986, as amended (the "Code") and
        therefore will not be treated as a taxable sale of your fund's shares.


     o  In most instances, the pro forma expense ratio for each of the combined
        Pioneer Funds' class of shares is anticipated to be the same or lower
        than the historical expense ratio of the corresponding class of shares
        of the fund being acquired.


     Therefore, your fund's Trustees recommend that you vote FOR the
Reorganization.


What are the Federal Income Tax Consequences of the Reorganizations

     The Reorganizations will not result in any income, gain or loss being
recognized for federal income tax purposes by any of the Pioneer Funds or their
shareholders as a direct result of the Reorganizations. However, in accordance
with the Pioneer Funds' policy to distribute its investment company taxable
income, net tax-exempt income and net capital gains for the taxable year (in
order to qualify for tax treatment as a regulated investment company and avoid
federal income tax thereon at the fund level), each Pioneer Fund that is being
merged into a corresponding Pioneer Fund will declare and pay a distribution of
such income and gains to its shareholders shortly before the Reorganizations.
Each such distribution, other than distributions of exempt-interest dividends,
will be taxable to those shareholders. Additionally, following the
Reorganizations, each Pioneer Fund will declare and pay before the end of 2006
a distribution of such income and gains to its shareholders. Those
distributions will be fully taxable to all shareholders of the Pioneer Funds,
including those of the merged Pioneer Funds, even though those distributions
may include a portion of the Pioneer Fund's income and gains that were realized
before the Closing Date.


Who Bears the Expenses Associated with the Reorganizations

     Pioneer has agreed to pay 50% of the costs of preparing and printing the
Proxy Statement/Prospectus and the solicitation costs incurred in connection
with the Reorganizations. The Pioneer Funds will each pay an equal portion of
the remaining 50% of the costs incurred in connection with the Reorganizations.



What Happens if a Reorganization is Not Approved


     If the required approval of shareholders of a Pioneer Fund is not
obtained, the meeting with respect to such Fund may be adjourned as more fully
described in this Proxy Statement/Prospectus, and such Fund will continue to
engage in the business as a separate mutual fund and the Board will consider
what further action may be appropriate.



                                       3


Who is Eligible to Vote?

     Shareholders of record on July 31, 2006 are entitled to attend and vote at
the meeting or any adjourned meeting. Each share is entitled to one vote.
Shares represented by properly executed proxies, unless revoked before or at
the meeting, will be voted according to shareholders' instructions. If you sign
a proxy but do not fill in a vote, your shares will be voted to approve the
Agreement and Plan of Reorganization. If any other business comes before the
meeting, your shares will be voted at the discretion of the persons named as
proxies.

                                    SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of
Agreement and Plan of Reorganization attached as Exhibit A, because they
contain details that are not in the summary.

     If Proposal 1(a) is approved, your fund will be reorganized into Pioneer
Government Income Fund, as described above.

     Both your fund and Pioneer Government Income Fund share a similar
investment objective of seeking current income as is consistent with the
preservation of capital and consequently, both funds have similar investment
policies and risks. However, Pioneer Government Income Fund may invest in a
broader range of U.S. government securities and derivatives, and is therefore
subject to additional risks associated with such investments. The table below
provides a comparison of the two funds. In the table below, if a row extends
across the entire table, the policy disclosed applies to both your fund and
Pioneer Government Income Fund.

                       Each fund may invest in mortgage-backed securities issued by agencies or instrumentalities of the U.S.
                       government. These securities represent direct or indirect participation in, or are collateralized by and
                       payable from, mortgage loans secured by real estate. Certain debt instruments may only pay principal at
                       maturity or may only represent the right to receive payments of principal or payments of interest on
                       underlying pools of mortgage or government securities, but not both. The value of these types of instruments
                       may change more drastically than debt securities that pay both principal and interest during periods of
                       changing interest rates. Principal only mortgage-backed securities generally increase in value if interest
                       rates decline, but are also subject to the risk of prepayment. Interest only instruments generally increase
                       in value in a rising interest rate environment when fewer of the underlying mortgages are prepaid.

                       Each fund may invest in repurchase agreements. Repurchase agreements are arrangements under which the fund
                       purchases securities and the seller agrees to repurchase the securities

                       within a specific time and at a specific price. The repurchase price is generally higher than a fund's
                       purchase price, with the difference being income to the fund. The other party's obligations under the
                       repurchase agreement are collateralized with U.S. Treasury and/or agency obligations with a market value of
                       not less than 100% of the obligations, valued daily. Repurchase agreements afford a fund an opportunity to
                       earn income on temporarily available cash at low risk. However, in the event that the other party to the
                       repurchase agreement defaults on its obligations, a fund may encounter delay and incur costs before being
                       able to sell the security. Such a delay may involve loss of interest or a decline in price of the security.
                       In addition, if a fund is characterized by a court as an unsecured creditor, it would be at risk of losing
                       some or all of the principal and interest involved in the transaction.

                       Each fund may purchase and sell securities, including GNMA certificates, on a when-issued or delayed delivery
                       basis. These transactions arise when securities are purchased or sold by a fund with payment and delivery
                       taking place at a fixed future date. Each fund will not earn income on these securities until delivered. Each
                       fund may engage in these transactions when it believes they would result in a favorable price and yield for
                       the security being purchased or sold. The market value of when-issued or delayed delivery transactions may
                       increase or decrease as a result of changes in interest rates. These transactions involve risk of loss if the
                       value of the underlying security changes unfavorably before the settlement date. There is also a risk that
                       the other party to the transaction will default on its obligation to purchase or sell the security, which may
                       result in a fund missing the opportunity to obtain a favorable price or yield elsewhere.

Investment strategies  Pioneer, each fund's investment adviser, considers both broad economic factors and issuer specific factors in
                       selecting a portfolio designed to achieve the fund's investment objective. In assessing the appropriate
                       maturity and sector weighting of a fund's portfolio, Pioneer considers a variety of factors that are expected
                       to influence economic activity and interest rates. These factors include fundamental economic indicators,
                       such as the rates of economic growth and inflation, Federal Reserve monetary policy and the relative value of
                       the U.S. dollar compared to other currencies. Once Pioneer determines the preferable portfolio
                       characteristics, Pioneer selects individual securities based upon the terms of the securities (such as yields
                       compared to U.S. Treasuries or comparable issues) and sector diversification.

                       In making portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff and the
                       staff of its affiliates who have access to a wide variety of research.

- ------------------------------------------------------------------------------------------------------------------------------------
Temporary defensive    Normally, each fund invests substantially all of its assets to meet its investment objective. Each fund may
strategies             invest the remainder of its assets in securities with remaining maturities of less than one year, cash
                       equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual cash
                       flows, each fund may depart from its principal investment strategies and invest part or all of its assets in
                       these securities or may hold cash. During such periods, a fund may not be able to achieve its investment
                       objective.
- ------------------------------------------------------------------------------------------------------------------------------------
Short-term trading     Each fund usually does 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
                       shareowners to incur a higher level of taxable income or capital gains.

Maximum purchase       Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares. There
amounts                is no maximum purchase for Class A shares or Class R shares. These limits are applied on a per
                       transaction basis.
- ------------------------------------------------------------------------------------------------------------------------------------
Exchanging shares      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. Each fund allows you to exchange your shares at net asset value
                       without charging you either an initial or contingent deferred shares 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. An exchange
                       generally is treated as a sale and a new purchase of shares for federal income tax purposes.

                       The fund is not offering additional Investor Class shares except in connection with the reinvestment of
                       dividends on the fund's outstanding Investor Class shares. Holders of Investor Class Shares of the fund
                       may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the
                       prospectus for that Class. All Investor Class shares of a fund, whenever issued, convert to Class A
                       shares of the fund on December 10, 2006.

                       In connection with the Reorganization, Pioneer Government Income Fund's Class A shareholders will have
                       the opportunity to exchange their shares for Class Y shares of Pioneer Government Income Fund at net
                       asset value without any initial or contingent sales charge.

                       After you establish an eligible fund account, you can exchange fund shares by telephone or online.
- ------------------------------------------------------------------------------------------------------------------------------------
Selling shares         Your shares will be sold at net asset value per share next calculated after a 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.

                       If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by
                       telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your
                       account is an eligible IRA (tax penalties may apply).
- ------------------------------------------------------------------------------------------------------------------------------------
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).
- ------------------------------------------------------------------------------------------------------------------------------------
                       You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge
                       unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C
                       shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares.

Comparison of Principal Risks of Investing in the Funds

     Because each fund has similar investment objectives and investment
strategies, the funds are subject to some of the same principal risks. You
could lose money on your investment or not make as much as if you invested
elsewhere if:

     o  Interest rates go up causing the value of the fund's investments to
        decline.

     o  During periods of declining interest rates, the issuer of a security may
        exercise its option to prepay principal earlier than scheduled, forcing
        the fund to reinvest in lower yielding securities. This is known as call
        or prepayment risk.


                                       13


     o  During periods of rising interest rates, the average life of certain
        types of securities may be extended because of slower than expected
        principal payments. This may lock in a below market interest rate,
        increase the security's duration (the estimated period until the
        security is paid in full) and reduce the value of the security. This is
        known as extension risk.

     o  Pioneer's judgment about the attractiveness, relative value or potential
        appreciation of a particular sector, security or investment strategy
        prove to be incorrect.

     To the extent either fund invests significantly in mortgage-backed
securities, its exposure to prepayment and extension risks may be greater than
other investments in fixed income securities.

     Unlike your fund, Pioneer Government Income Fund is subject to the risks
of investing in government-sponsored entities. Government sponsored entities
such as the Federal Home Loan Mortgage Corporation (Freddie Mac), the Federal
National Mortgage Association (FNMA) and the Federal Home Loan Banks (FHLBs),
although chartered or sponsored by Congress, are not funded by congressional
appropriations and the debt and mortgage-backed securities issued by them are
neither guaranteed nor issued by the U.S. government.


The Funds' Fees and Expenses

     Shareholders of both funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay
if you were to buy and hold shares of each fund. The expenses in the tables
appearing below are based on (i) for your fund, the expenses of your fund for
the twelve-month period ended December 31, 2005, and (ii) for Pioneer
Government Income Fund, the expenses of Pioneer Government Income Fund for the
twelve-month period ended January 31, 2006. Future expenses for all share
classes may be greater or less. The tables also show the pro forma expenses of
the combined fund assuming the Reorganization occurred on January 31, 2006.

     The hypothetical examples below help you compare the cost of investing in
each fund. It assumes that: (a) you invest $10,000 in each fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each fund's operating expenses remain
the same and (e) Pioneer's contractual expense limitation for the combined
Pioneer Government Income Fund's Class B shares is in effect for year one. Pro
forma expenses are included assuming a Reorganization with your fund and
Pioneer Government Income Fund. The examples are for comparison purposes only
and are not a representation of either fund's actual expenses or returns,
either past or future.

(1) Purchases of $1 million or more and purchases by participants in certain
    group plans are not subject to an initial sales charge but may be subject to
    a contingent deferred sales charge of 1%.

(2) The funds' total annual operating expenses in the table have not been
    reduced by any expense offset arrangements.

(3) Net expenses in the table reflect the expense limitation that will be in
    effect upon the closing of the Reorganization, under which Pioneer has
    contractually agreed not to impose all or a portion of its management fee
    and, if necessary, to limit other ordinary operating expenses to the extent
    required to reduce fund expenses to 1.89% of the average daily net assets
    attributable to Class B shares. This expense limitation is in effect from
    the closing date of the Reorganization through December 1, 2007. There can
    be no assurance that Pioneer will extend the expense limitation beyond such
    time.

(4) The funds' Investor Class shares, whenever issued, convert to Class A shares
    of the fund on December 10, 2006.

Comparison of Fund Performance

     The bar charts show the year-by-year performance of each fund's Class A
shares since inception. Class B, Class C, Class R and Investor Class shares
will have different performance. The chart does not reflect any sales charge
you may pay when you buy or sell fund shares. Any sales charge will reduce your
return. The tables show average annual total return (before and after sales
taxes) for each fund over time for each class of shares (including deductions
for sales charges) compared with a broad-based securities market index. The
after-tax returns shown for each fund are for Class A only; after-tax returns
for other classes will vary. Past performance (before and after taxes) does not
indicate future results.

* During the period shown in the bar chart, Pioneer America Income Trust's
 highest quarterly return was 4.51% for the quarter ended September 30, 2001,
 and the lowest quarterly return was (2.07)% for the quarter ended March 31,
 1996. For the period from January 1, 2006 to June 30, 2006, Pioneer America
 Income Trust's return was (1.68%).

     Pursuant to an agreement and plan of reorganization, Pioneer Government
Income Fund acquired the assets and liabilities of AmSouth Government Income
Fund (the predecessor fund) on September 23, 2005. In the reorganization, the
predecessor fund exchanged all of its assets for shares of the fund. The
predecessor fund offered classes of shares similar to the fund's Class A and
Class B shares. As a result of the reorganization, the fund is the accounting
successor of the predecessor fund. The performance of the Class A and Class B
shares of the fund set forth in the table below includes the performance of the
predecessor fund's Class A and Class B shares prior to the Reorganization,
which has been restated to reflect differences in any applicable sales charges
(but not differences in expenses). Class C shares were not previously offered
by the predecessor fund. The performance of the fund's Class C shares is based
upon the performance of the predecessor fund's Class B shares as adjusted to
reflect sales charges applicable to the fund's Class C shares (but not other
differences in expenses). If the performance had been adjusted to reflect all
differences in expenses, the performance of the fund would be lower.

    and may differ from those shown. Furthermore, the after-tax returns shown
    are not relevant to shareholders who hold fund shares through tax-deferred
    arrangements such as 401(k) plans or individual retirement accounts.
    After-tax returns for Class B and Class C shares will vary from the
    after-tax returns presented for Class A shares.

                                CAPITALIZATION

     The following table sets forth the capitalization of each fund as of May
31, 2006 and the pro forma combined capitalization of the combined fund as if
the Reorganization had occurred on that date. If the Reorganization is
consummated, the actual exchange ratios on the Closing Date may vary from the
exchange ratios indicated. This is due to changes in the market value of the
portfolio securities of both funds between May 31, 2006 and the Closing Date,
changes in the amount of undistributed net investment income and net realized
capital gains of both funds during that period resulting from income and
distributions, and changes in the accrued liabilities of both funds during the
same period.

     It is impossible to predict how many shares of Pioneer Government Income
Fund will actually be received and distributed by your fund on the Closing
Date. The table should not be relied upon to determine the amount of Pioneer
Government Income Fund shares that will actually be received and distributed.

         PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION

The Reorganization


     o  The Reorganization is scheduled to occur as of the close of business on
        November 10, 2006, but may occur on such later date as the parties may
        agree in writing. Your fund will transfer all of its assets to Pioneer
        Government Income Fund, and Pioneer Government Income Fund will assume
        all of your fund's liabilities. This will result in the addition of your
        fund's assets to Pioneer Government Income Fund's portfolio. The net
        asset value of both funds will be computed as of the close of regular
        trading on the New York Stock Exchange on the Closing Date.


     o  Pioneer Government Income Fund will issue to your fund Class A shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class A shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class A shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class A shareholders of your fund will end up as Class A
        shareholders of Pioneer Government Income Fund.

     o  Pioneer Government Income Fund will issue to your fund Class B shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class B shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class B shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class B shareholders of your fund will end up as Class B
        shareholders of Pioneer Government Income Fund.

     o  Pioneer Government Income Fund will issue to your fund Class C shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class C shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class C shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class C shareholders of your fund will end up as Class C
        shareholders of Pioneer Government Income Fund.

     o  Pioneer Government Income Fund will issue to your fund Class R shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class R shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class R shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class R shareholders of your fund will end up as Class R
        shareholders of Pioneer Government Income Fund.

     o  Pioneer Government Income Fund will issue to your fund Investor Class
        shares with an aggregate net asset value equal to the net assets
        attributable to your fund's Investors Class shares. As part of the
        liquidation of your fund, these shares will immediately be distributed
        to Investor Class shareholders of record of your fund in proportion to
        their holdings on the Closing Date. As a result, Investor Class
        shareholders of your fund will end up as Investor Class shareholders of
        Pioneer Government Income Fund. All Investor Class shares of Pioneer
        Government Income Fund, whenever issued, convert to Class A shares of
        Pioneer Government Income Fund on December 10, 2006.

     o  After the shares are issued, your fund will be dissolved.

Reasons for the Proposed Reorganization

     The Trustees of your fund believe that the proposed Reorganization will be
advantageous to the shareholders of your fund for several reasons. The Trustees
considered the following matters, among others, in approving the proposal.

     First, the Reorganization would eliminate confusion in the marketplace
caused by having two substantially similar funds and enhancing the potential
for one of the two funds to achieve growth in assets. The combined fund may be
better positioned to attract assets than your fund. After the Reorganization,
the combined fund's greater asset size may allow it, relative to your fund, to
(i) obtain better net prices on securities trades, and (ii) reduce per share
expenses as fixed expenses are shared over a larger asset base.


     Second, the long-term historical investment performance of each fund is
similar. Although Pioneer America Income Trust's average annual total returns
for the one- and five-year periods is higher, Pioneer Government Income Fund's
long-term performance for the 10-year period is higher. For the one, five and
10-year periods ended December 31, 2005, Class A shares of Pioneer Government
Income Fund had average annual total returns of -3.04% (one year); 3.21% (five
year); and 4.75% (10 year), compared to average annual total returns of the
Class A shares of Pioneer America Income Trust of -2.73% (one year); 3.36%
(five year); and 4.38% (10 year), during the same periods.



                                       20



     Third, since the management fee rate is the same for both funds, there
will be no increase in management fee (as a percentage of average daily net
assets) as a result of the Reorganization. With the exception of Class C
shares (due to its relatively small size), the historical total expenses of
Pioneer Government Income Fund's shares are lower than Pioneer America Income
Trust's historical expenses for its shares. In addition, it is anticipated that
the pro forma expense ratio for each class of shares will be the same or lower
than the historical expense ratio of Pioneer America Income Trust after the
Reorganization and has the potential to decrease further with asset growth.
Pioneer has agreed not to impose all or a portion of its management fee and, if
necessary, to limit other ordinary operating expenses to the extent required to
limit Pioneer Government Income Fund's Class B shares to 1.89% of the average
daily net assets attributable to Class B shares through December 1, 2007.
Although Pioneer Government Income Fund has historically not had Class R or
Investor Class shares outstanding, these classes will be issued in the
Reorganization, and the resulting expense ratio of each is expected to be
approximately the same as the expense ratio of your fund's Class R and
Investor Class shares.


     The Boards of both funds considered that each fund would bear equally half
of all of the expenses associated with the preparation, printing and mailing of
any shareholder communications, including this Proxy Statement/Prospectus, and
any filings with the SEC and other governmental agencies in connection with the
Reorganization. Pioneer will bear the balance of these expenses. The Boards of
both funds estimate that these expenses in the aggregate will not exceed
$84,500.

     The Boards of both funds considered that the funds' investment adviser and
principal distributor would benefit from the Reorganization. For example,
Pioneer might achieve cost savings from managing one larger fund compared to
managing more than one fund with similar investment strategies, which would
result in a decrease in the combined fund's gross expenses and a corresponding
decrease in fees waived under the current expense limit agreement. The Boards
believe, however, that these savings will not amount to a significant economic
benefit to Pioneer or the principal distributor.

     The Boards of Trustees of both funds also considered that the
Reorganization presents an excellent opportunity for the shareholders of each
fund to become investors in a combined fund that has a larger asset size than
either fund alone without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to both funds and their shareholders.


                     BOARDS' EVALUATION AND RECOMMENDATION

     For the reasons described above, the Board of Trustees of your fund,
including the Independent Trustees, approved the Reorganization. In particular,
the Trustees determined that the Reorganization is in the best interest 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 Pioneer
Series Trust IV, including the Independent Trustees, approved the
Reorganization. They also determined that the Reorganization is in the best
interests of Pioneer Government Income Fund and that the interests of Pioneer
Government Income Fund's shareholders would not be diluted as a result of the
Reorganization.

     The Trustees of your fund recommend that shareholders of your fund vote
FOR the proposal to approve the Agreement and Plan of Reorganization.

                                  PROPOSAL 1(b)


                                     SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of
Agreement and Plan of Reorganization attached as Exhibit A, because they
contain details that are not in the summary.

     If Proposal 1(b) is approved, your fund will be reorganized into Pioneer
Classic Balanced Fund, as described above.

     Each fund has substantially similar investment objectives and principal
investment strategies, except that Pioneer Classic Balanced Fund's investment
strategy focuses on value-oriented equity securities while your fund focuses on
growth-oriented equity securities. The table below provides a comparison of the
two funds. In the table below, if a row extends across the entire table, the
policy disclosed applies to both your fund and Pioneer Classic Balanced Fund.

Primary investments     Pioneer allocates each fund's assets between equity and debt securities based on its assessment of
                        current business, economic and market conditions. Normally, equity and debt securities each represent
                        35% to 65% of each fund's net assets. For purposes of each fund's investment policies, equity
                        investments include common stocks, convertible debt and securities with common stock characteristics,
                        such as equity interests in real estate investment trusts (REITs), exchange-traded funds (ETFs) that
                        invest primarily in equity securities and preferred stocks. Each fund's investments in debt securities
                        include U.S. government securities, corporate debt securities, mortgage- and asset-backed securities,
                        short term debt securities, cash and cash equivalents. Cash and cash equivalents include cash balances,
                        accrued interest and receivables for items such as the proceeds, not yet received, from the sale of a
                        fund's portfolio investments.

                        Debt securities in which each fund invests may have fixed or variable principal payments and all types
                        of interest rate payment and reset terms, including fixed rate, adjustable rate, zero coupon,
                        contingent, deferred, payment-in-kind and auction rate features.

                        Each fund may invest up to 25% of its total assets in equity and debt securities of non-U.S. issuers.
                        Each fund will not invest more than 5% of its total assets in the securities of emerging markets
                        issuers. Each fund invests in non-U.S. securities to diversify its portfolio when they offer similar or
                        greater potential for capital appreciation.

                        Each fund may invest in U.S. government securities. U.S. government securities include obligations:
                        directly issued by or supported by the full faith and credit of the U.S. government, like Treasury
                        bills, notes and bonds and Government National Mortgage Association certificates; supported by the right
                        of the issuer to borrow from the U.S. Treasury, like those of the Federal Home Loan Banks; supported by
                        the discretionary authority of the U.S. government to purchase the agency's securities like those of the
                        Federal National Mortgage Association; or supported only by the credit of the issuer itself, like the
                        Tennessee Valley Authority.

                        Each fund may invest in mortgage-backed and asset-backed securities. Mortgage-related securities may be
                        issued by private companies or by agencies of the U.S. government and represent direct or indirect
                        participation in, or are collateralized by and payable from, mortgage loans secured by real property.
                        Asset-backed securities represent participations in, or are secured by and payable from, assets such as
                        installment sales or loan contracts, leases, credit card receivables and other categories of
                        receivables.

                        In pursuing its investment strategy, Pioneer Classic Balanced Fund may over time dispose of securities
                        acquired through the reorganization in the ordinary course of business. This may result in Pioneer
                        Classic Balanced Fund realizing gains on previously existing Pioneer Balanced Fund holdings, which
                        capital gains will be distributed to all of Pioneer Classic Balanced Fund's shareholders after the
                        closing date, and incurring transactions costs. The amount of such gains and any transaction costs
                        cannot be accurately estimated at this time. Pioneer intends to take such factors into consideration in
                        selecting any portfolio positions for sale.

Investment strategies   In selecting equity securities, Pioneer seeks         In selecting equity securities, Pioneer uses a
                        securities selling at reasonable prices and then      value approach to select the fund's
                        holds these securities until the market values        investments. Using this investment style,
                        reflect their intrinsic values.                       Pioneer seeks securities selling at reasonable
                                                                              prices or substantial discounts to their
                                                                              underlying values and then holds these
                                                                              securities until the market values reflect their
                                                                              intrinsic values.
- ------------------------------------------------------------------------------------------------------------------------------------
                        Pioneer evaluates a security's potential value, including the attractiveness of its market valuation,
                        based on the company's assets and prospects for earnings growth. In making that assessment, Pioneer
                        employs due diligence and fundamental research, an evaluation of the issuer based on its financial
                        statements and operations. Pioneer also considers a security's potential to provide a reasonable amount
                        of income. Pioneer relies on the knowledge, experience and judgment of its staff who have access to a
                        wide variety of research. Pioneer focuses on the quality and price of individual issuers, not on
                        economic sector or market-timing strategies. Factors Pioneer looks for in selecting investments include:

                        o Favorable expected returns relative to perceived risk

                        o Above average potential for earnings and revenue growth

                        o Low market valuations relative to earnings forecast, book value, cash flow and sales

                        o A sustainable competitive advantage, such as a brand name, customer base, proprietary technology or
                          economics of scale.

                        In selecting debt securities, Pioneer considers both broad economic and issuer specific factors in
                        selecting a portfolio designed to achieve the fund's investment objectives. In assessing the appropriate
                        maturity, rating and sector weighting of the fund's portfolio, Pioneer considers a variety of factors
                        that are expected to influence economic activity and interest rates. These factors include fundamental
                        economic indicators, such as the rates of economic growth and inflation, Federal Reserve monetary policy
                        and the relative value of the U.S. dollar compared to other currencies. Once Pioneer determines the
                        preferable portfolio characteristics, Pioneer selects individual securities based upon the terms of the
                        securities (such as yields compared to U.S. Treasuries or comparable issuers), liquidity and rating,
                        sector and issuer diversification. Pioneer also employs fundamental research and due diligence to assess
                        an issuer's credit quality, taking into account financial condition and profitability, future capital
                        needs, potential for change in rating, industry outlook, the competitive environment and management
                        ability.

                        In making portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff and
                        the staff of its affiliates who have access to a wide variety of research.
- ------------------------------------------------------------------------------------------------------------------------------------
                         Pioneer generally sells a portfolio security
                         when it believes that the issuer no longer
                         offers the potential for above average earnings
                         and revenue growth. Pioneer makes that
                         determination based upon the same criteria it
                         uses to select portfolio securities.

Other investments       Up to 10% of each fund's total assets may be invested in debt securities rated below investment grade,
                        including convertible debt. A debt security is investment grade if it is rated in one of the top four
                        categories by a nationally recognized statistical rating organization or determined to be of equivalent
                        credit quality by Pioneer. Debt securities rated below investment grade are commonly referred to as
                        "junk bonds" and are considered speculative. Below investment grade debt securities involve greater risk
                        of loss, are subject to greater price volatility and are less liquid, especially during periods of
                        economic uncertainty or change, than higher quality debt securities. Each fund may invest in debt
                        securities rated "D" or higher by a nationally recognized statistical rating organization.

                        For purposes of each fund's credit quality policies, if a security receives different ratings from
                        nationally recognized statistical rating organizations, each fund will use the rating chosen by the
                        portfolio manager as most representative of the security's credit quality. If a rating organization
                        changes the quality rating assigned to one or more of each fund's portfolio securities, Pioneer will
                        consider if any action is appropriate in light of the fund's investment objective and policies.
- ------------------------------------------------------------------------------------------------------------------------------------
Derivatives             The funds may use futures and options on securities, indices and currencies, forward foreign currency
                        exchange contracts 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. Although there is no specific limitation on investing in
                        derivatives, neither fund uses derivatives as a primary investment technique and generally limits their
                        use to hedging. However, each fund may use derivatives for a variety of non-principal purposes,
                        including:

                        o As a hedge against adverse changes in market prices of securities, interest rates or currency exchange
                          rates

                        o As a substitute for purchasing or selling securities

                        o To increase the fund's return as a non-hedging strategy that may be considered speculative

                        Even a small investment in derivatives can have a significant impact on the funds' exposure to the
                        market prices of securities, interest rates or currency exchange rates. If changes in a derivative's
                        value do not correspond to changes in the value of the funds' other investments, the funds 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. The funds will only invest in derivatives to the extent Pioneer
                        believes these investments do not prevent the funds from seeking their investment objective.
- ------------------------------------------------------------------------------------------------------------------------------------

Temporary defensive     Normally, each fund invests substantially all of its assets to meet its investment objective. Each fund
strategies              may invest the remainder of its assets in securities with remaining maturities of less than one year,
                        cash equivalents or may hold cash. For temporary defensive purposes, including during periods of unusual
                        cash flows, each fund may depart from its principal investment strategies and invest part or all of its
                        assets in these securities or may hold cash. During such periods, a fund may not be able to achieve its
                        investment objective.
- ------------------------------------------------------------------------------------------------------------------------------------
Short-term trading      Each fund usually does 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
                        the funds do a lot of trading, they may incur additional operating expenses, which would reduce
                        performance, and could cause shareowners to incur a higher level of taxable income or capital gains.

and fees
                        o Class B shares are offered without an initial sales charge, but are subject to contingent deferred
                          sales charges of up to 4% if you sell your shares. The charge is reduced over time and is not charged
                          after five years. Your investment firm may receive a commission from PFD, the funds' distributor, at the
                          time of your purchase of up to 4%.

                        o Class B shares are subject to distribution and service (12b-1) fees of up to 1% of average daily net
                          assets. Both of these fees are paid out of a fund's assets on an ongoing basis. Over time these fees
                          will increase the cost of investments and may cost more than other types of sales charges.

                          purchase of up to 1%.

                        o Class C shares are subject to distribution and service (12b-1) fees of up to 1% of average daily net

Management fees         Both funds have the same management fee structure. Pioneer's annual fee is equal to 0.65% of each fund's
                        average daily net assets up to $1 billion, 0.60% of the next $4 billion and 0.55% on the assets over $5
                        billion. The fee is accrued daily and paid monthly.

                        A discussion regarding the basis for the Board of Trustees' approval of the management contract is
                        available in Pioneer Balanced Fund's December 31, 2005 annual report to shareholders and in Pioneer

 Buying shares          You may buy shares from any investment firm that has a sales agreement with PFD, the funds' distributor.
                        You can buy shares at the offering price. You may use securities you own to purchase shares of the fund
                        provided that Pioneer, in its sole discretion, determines that the securities are consistent with the
                        fund's objective and policies and their acquisition is in the best interests of the fund.

                        Investor Class shares have been issued in connection with the Reorganization. The fund is not offering
                        additional Investor Class shares except in connection with the reinvestment of dividends on the fund's
                        outstanding Investor Class shares. Holders of Investor Class Shares of the fund may be eligible to
                        purchase Class A shares of the fund without paying a sales load, pursuant to the prospectus for that
                        Class. All Investor Class shares of the fund, whenever issued, convert to Class A shares of the fund on
                        December 10, 2006.

                        If you have an existing non-retirement account, you may purchase shares of a fund by telephone or
                        online. Certain IRAs also may use the telephone purchase privilege.
- ------------------------------------------------------------------------------------------------------------------------------------
Minimum initial
investment              Your initial investment must be at least $1,000 for Class A, Class B or Class C shares. Additional
                        investments must be at least $100 for Class A shares, $500 for Class B shares 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.
- ------------------------------------------------------------------------------------------------------------------------------------
Maximum purchase
amounts                 Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares.
                        There is no maximum purchase for Class A shares. These limits are applied on a per transaction basis.
- ------------------------------------------------------------------------------------------------------------------------------------
Exchanging shares       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. Each fund allows you to exchange your shares at net asset value
                        without charging you either an initial or contingent deferred shares 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. An exchange
                        generally is treated as a sale and a new purchase of shares for federal income tax purposes.

                        The fund is not offering additional Investor Class shares except in connection with the reinvestment of
                        dividends on the fund's outstanding Investor Class shares. Holders of Investor Class shares of the Fund
                        may be eligible to purchase Class A shares of the fund without paying a sales load, pursuant to the
                        prospectus for that Class. All Investor Class shares of the fund, whenever issued, convert to Class A
                        shares of the fund on December 10, 2006.

                        After you establish an eligible fund account, you can exchange fund shares by telephone or online.
- ------------------------------------------------------------------------------------------------------------------------------------
Selling shares          Your shares will be sold at net asset value per share next calculated after a 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.

                        If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by
                        telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your
                        account is an eligible IRA (tax penalties may apply).
- ------------------------------------------------------------------------------------------------------------------------------------
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).

                        unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C
                        shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares.

Comparison of Principal Risks of Investing in the Funds

     Because each fund has substantially similar investment objectives and
investment strategies, the funds are also subject to some of the same risks.
You could lose money on your investment or not make as much as if you invested
elsewhere if:

     o  The stock market goes down or performs poorly relative to other
        investments (this risk may be greater in the short term)

     o  The fund's equity investments do not have the growth potential
        originally expected

     o  Stocks selected for income do not achieve the same return as securities
        selected for capital growth

     o  Value stocks fall out of favor with investors

     o  The fund's assets remain undervalued or do not have the potential value
        originally expected

     Risks of debt securities. Each fund has risks associated with investing in
debt securities. Each fund could underperform other investments if:

     o  Interest rates go up causing the value of the fund's portfolio to
        decline

     o  The issuer of a debt security owned by the fund defaults on its
        obligation to pay principal or interest or has its credit rating
        downgraded

     o  During periods of declining interest rates, the issuer of a security may
        exercise its option to prepay principal earlier than scheduled, forcing
        the fund to reinvest in lower yielding securities. This is known as call
        or prepayment risk

     o  During periods of rising interest rates, the average life of certain
        types of securities may be extended because of slower than expected
        principal payments. This may lock in a below market interest rate,
        increase the security's duration (the estimated period until the
        security is paid in full) and reduce the value of the security. This is
        known as extension risk

     o  Pioneer's judgment about the attractiveness, relative value or potential
        appreciation of a particular sector, security or investment strategy
        proves to be incorrect

     Non-U.S. securities risks. Each fund may invest in non-U.S. securities.
Investing in non-U.S. issuers may involve unique risks compared to investing in
securities of U.S. issuers. These risks are more pronounced for issuers in
emerging markets or to the extent that the fund invests significantly in one
region or country. These risks may include:

     o  Less information about non-U.S. issuers or markets may be available due
        to less rigorous disclosure or accounting standards or regulatory
        practices

     o  Many non-U.S. markets are smaller, less liquid and more volatile. In a
        changing market, Pioneer may not be able to sell the fund's portfolio
        securities at times, in amounts and at prices it considers reasonable

     o  Adverse effect of currency exchange rates or controls on the value of
        the fund's investments

     o  The economies of non-U.S. countries may grow at slower rates than
        expected or may experience a downturn or recession

     o  Economic, political and social developments may adversely affect the
        securities markets

     o  Withholding and other non-U.S. taxes may decrease the fund's return

     Risks of REITs. Both funds may invest in REITs but to different degrees.
REITs are companies that invest primarily in real estate or real estate related
loans. Investing in REITs involves unique risks. They are significantly
affected by the market for real estate and are dependent upon management skills
and cash flow. In addition to its own expenses, the fund will indirectly bear
its proportionate share of any management and other expenses paid by REITs in
which it invests.


                                       29


     Risks of mortgage- and asset-backed securities and mortgage derivatives.
Certain debt instruments may only pay principal at maturity or may only
represent the right to receive payments of principal or payments of interest on
underlying pools of mortgage or government securities, but not both. The value
of these types of instruments may change more drastically than debt securities
that pay both principal and interest during periods of changing interest rates.
Principal only instruments generally increase in value if interest rates
decline, but are also subject to the risk of prepayment. Interest only
instruments generally increase in value in a rising interest rate environment
when fewer of the underlying mortgages are prepaid.

     Pioneer Balanced Fund may invest in mortgage derivatives and structured
securities that have imbedded leverage features. As a result, small changes in
interest or prepayment rates may cause large and sudden price movements.
Mortgage derivatives can also become illiquid and hard to value in declining
markets.


     Market segment risks. To the extent either fund emphasizes, from time to
time, investments in a market segment, the fund will be subject to a greater
degree to the risks particular to the industries in that segment, and may
experience greater market fluctuation, than a fund without the same focus. For
example, industries in the financial segment, such as banks, insurance
companies, broker-dealers and REITs, may be sensitive to changes in interest
rates and general economic activity and are subject to extensive government
regulation. Industries in the technology segment, such as information
technology, communications equipment, computer hardware and software, and
office and scientific equipment, are subject to risks of rapidly evolving
technology, short product lives, rates of corporate expenditures, falling
prices and profits, competition from new market entrants, and general economic
conditions.



The Funds' Fees and Expenses

     Shareholders of both funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay
if you were to buy and hold shares of each fund. The expenses in the tables
appearing below are based on (i) for your fund, the expenses of your fund for
the twelve-month period ended December 31, 2005, and (ii) for Pioneer Classic
Balanced Fund, the expenses of Pioneer Classic Balanced Fund for the
twelve-month period ended January 31, 2006. Future expenses for all share
classes may be greater or less. The tables also show the pro forma expenses of
the combined fund assuming the Reorganization occurred on January 31, 2006.

     The hypothetical examples below help you compare the cost of investing in
each fund. It assumes that: (a) you invest $10,000 in each fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each fund's operating expenses remain
the same, and (e) Pioneer's contractual expense limitation for the combined
Pioneer Classic Balanced Fund's Class A, Class B and Class C shares is in
effect for year one. Pro forma expenses are included assuming a Reorganization
with your fund and Pioneer Classic Balanced Fund. The examples are for
comparison purposes only and are not a representation of either fund's actual
expenses or returns, either past or future.

(1)  Purchases of $1 million or more and purchases by participants in certain
     group plans are not subject to an initial sales charge but may be subject
     to a contingent deferred sales charge of 1%.

(2)  The funds' total annual operating expenses in the table have not been
     reduced by any expense offset arrangements.

(3)  Net expenses in the table reflect the expense limitations that will be in
     effect upon the closing of the Reorganization, under which Pioneer has
     contractually agreed to limit ordinary operating expenses to the extent
     required to reduce fund expenses to 1.16%, 2.06% and 2.06% of the average
     daily net assets attributable to Class A, Class B and Class C shares,
     respectively. These expense limitations are in effect through December 1,
     2009 for Class A shares and through December 1, 2007 for Class B and Class
     C shares. There can be no assurance that Pioneer will extend the expense
     limitations beyond such time. See the statement of additional information
     for details regarding the expense limitation agreement.

(4)  The funds' Investor Class shares, whenever issued, convert to Class A
     shares of the fund on December 10, 2006.

Comparison of Fund Performance

     The bar charts show the year-by-year performance of each fund's Class A
shares since inception. Class B, Class C and Investor Class shares will have
different performance. The chart does not reflect any sales charge you may pay
when you buy or sell fund shares. Any sales charge will reduce your return. The
tables show average annual total return (before and after sales taxes) for each
fund over time for each class of shares (including deductions for sales
charges) compared with a broad-based securities market index. The after-tax
returns shown for each fund are for Class A only; after-tax returns for other
classes will vary. Past performance (before and after taxes) does not indicate
future results.

     Pioneer Balanced Fund began to invest for capital growth and current
income in February 1997. Before that time, Pioneer Balanced Fund's objective
was income from a portfolio of income producing bonds and stocks.

* During the period shown in the bar chart, Pioneer Balanced Fund's highest
  quarterly return was 8.99% for the quarter ended June 30, 2003, and the
  lowest quarterly return was (11.66)% for the quarter ended September 30,
  2002. For the period from January 1, 2006 to June 30, 2006, Pioneer Balanced
  Fund's return was 0.00%.

     Pursuant to an agreement and plan of reorganization, the Pioneer Classic
Balanced Fund acquired the assets and liabilities of AmSouth Balanced Fund (the
predecessor fund) on September 23, 2005. In the reorganization, the predecessor
fund exchanged all of its assets for shares of the fund. The predecessor fund
offered classes of shares similar to the fund's Class A and Class B shares. As
a result of the Reorganization, the fund is the accounting successor of the
predecessor fund. The performance of the Class A and Class B shares of the fund
set forth in the table below includes the performance of the predecessor fund's
Class A and Class B shares prior to the reorganization, which has been restated
to reflect differences in any applicable sales charges (but not differences in
expenses). Class C shares were not previously offered by the predecessor fund.
The performance of the fund's Class C shares is based upon the performance of
the predecessor fund's Class B shares as adjusted to reflect sales charges
applicable to the fund's Class C shares (but not other differences in
expenses). If the performance had been adjusted to reflect all differences in
expenses, the performance of the fund would be lower.

(1) After-tax returns are calculated using the historical highest individual
    federal marginal income tax rates and do not reflect the impact of state and
    local taxes. Actual after-tax returns depend on the investor's tax situation
    and may differ from those shown. Furthermore, the after-tax returns shown
    are not relevant to shareholders who hold fund shares through tax-deferred
    arrangements such as 401(k) plans or individual retirement accounts.
    After-tax returns for Class B and Class C shares will vary from the
    after-tax returns presented for Class A shares.

(2) The performance of Class C shares does not reflect the 1% front-end sales
    charge in effect prior to February 1, 2004. If you paid a 1% sales charge,
    your returns would be lower than those shown above.

     The following table sets forth the capitalization of each fund as of May
31, 2006 and the pro forma combined capitalization of both funds as if the
Reorganization had occurred on that date. If the Reorganization is consummated,
the actual exchange ratios on the Closing Date may vary from the exchange
ratios indicated. This is due to changes in the market value of the portfolio
securities of both funds between May 31, 2006 and the Closing Date, changes in
the amount of undistributed net investment income and net realized capital
gains of both funds during that period resulting from income and distributions,
and changes in the accrued liabilities of both funds during the same period.

         PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION


The Reorganization


     o  The Reorganization is scheduled to occur as of the close of business on
        November 10, 2006, but may occur on such later date as the parties may
        agree in writing. Your fund will transfer all of its assets to Pioneer
        Classic Balanced Fund, and Pioneer Classic Balanced Fund will assume all
        of your fund's liabilities. This will result in the addition of your
        fund's assets to Pioneer Classic Balanced Fund's portfolio. The net
        asset value of both funds will be computed as of the close of regular
        trading on the New York Stock Exchange on the Closing Date.


     o  Pioneer Classic Balanced Fund will issue to your fund Class A shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class A shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class A shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class A shareholders of your fund will end up as Class A
        shareholders of Pioneer Classic Balanced Fund.

     o  Pioneer Classic Balanced Fund will issue to your fund Class B shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class B shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class B shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class B shareholders of your fund will end up as Class B
        shareholders of Pioneer Classic Balanced Fund.

     o  Pioneer Classic Balanced Fund will issue to your fund Class C shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class C shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class C shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class C shareholders of your fund will end up as Class C
        shareholders of Pioneer Classic Balanced Fund.

     o  Pioneer Classic Balanced Fund will issue to your fund Investor Class
        shares with an aggregate net asset value equal to the net assets
        attributable to your fund's Investors Class shares. As part of the
        liquidation of your fund, these shares will immediately be distributed
        to Investor Class shareholders of record of your fund in proportion to
        their holdings on the Closing Date. As a result, Investor Class
        shareholders of your fund will end up as Investor Class shareholders of
        Pioneer Classic Balanced Fund. All Investor Class shares of Pioneer
        Classic Balanced Fund, whenever issued, convert to Class A shares of
        Pioneer Classic Balanced Fund on December 10, 2006.

     o  After the shares are issued, your fund will be dissolved.

Agreement and Plan of Reorganization

     The shareholders of your fund are being asked to approve the Agreement, the
form of which is attached to this Proxy Statement/ Prospectus as Exhibit A and
incorporated herein by this reference. The description of the Agreement
contained herein, which include all the material provisions of the Agreement, is
qualified in its entirety by the attached copy.

Reasons for the Proposed Reorganization

     The Trustees of your fund believe that the proposed Reorganization will be
advantageous to the shareholders of your fund for several reasons. The Trustees
considered the following matters, among others, in approving the proposal.

     First, the Reorganization would eliminate confusion in the marketplace
caused by having two substantially similar funds and enhancing the potential
for one of the two funds to achieve growth in assets. The combined fund may be
better positioned to attract assets than your fund. After the Reorganization,
the combined fund's greater asset size may allow it, relative to your fund, to
(i) obtain better net prices on securities trades, and (ii) reduce per share
expenses as fixed expenses are shared over a larger asset base.


     Second, the long-term historical investment performance of Pioneer Classic
Balanced Fund is higher than your fund. For the one, five and 10-year periods
ended December 31, 2005, Class A shares of Pioneer Classic Balanced Fund had
average annual total returns of -0.08% (one year); 3.92% (five year); and 7.33%
(10 year), compared to average annual total returns of the Class A shares of
Pioneer Balanced Fund of -1.42% (one year); 0.59% (five year); and 3.55% (10
year), during the same periods.


     Third, since the management fee rate is the same for both funds, there
will be no increase in management fee (as a percentage of average daily net
assets) as a result of the Reorganization. The historical total expenses of
Pioneer Classic Balanced Fund for Class A, Class B and Class C shares are lower
than Pioneer Balanced Fund's historical expenses for Class A, Class B and Class
C shares. In addition, it is anticipated that the pro forma expense ratio for
each class of shares will be lower than the historical expense ratio of Pioneer
Balanced


                                       36



Fund after the Reorganization and has the potential to decrease further with
asset growth. Pioneer has agreed not to impose all or a portion of its
management fee and, if necessary, to limit other ordinary operating expenses to
the extent required to reduce Pioneer Classic Balanced Fund's expenses to
1.16%, 2.06% and 2.06% of the average daily net assets attributable to Class A,
Class B and Class C shares, respectively. These expense limitations are in
effect through December 1, 2009 for Class A shares and through December 1, 2007
for Class B and Class C shares. Although Pioneer Classic Balanced Fund has
historically not had Investor Class shares outstanding, this class will be
issued in the Reorganization, and the resulting expense ratio is expected to be
approximately the same as the expense ratio of your fund's Investor Class
shares.


     The Boards of both funds considered that each fund would bear equally half
of all of the expenses associated with the preparation, printing and mailing of
any shareholder communications, including this Proxy Statement/Prospectus, and
any filings with the SEC and other governmental agencies in connection with the
Reorganization. Pioneer will bear the balance of these expenses. The Boards of
both funds estimate that these expenses in the aggregate will not exceed
$78,500.

     The Boards of both funds considered that the funds' investment adviser and
principal distributor would benefit from the Reorganization. For example,
Pioneer might achieve cost savings from managing one larger fund compared to
managing more than one fund with similar investment strategies, which would
result in a decrease in the combined fund's gross expenses and a corresponding
decrease in fees waived under the current expense limit agreement. The Boards
believe, however, that these savings will not amount to a significant economic
benefit to Pioneer or the principal distributor.

     The Boards of Trustees of both funds also considered that the
Reorganization presents an excellent opportunity for the shareholders of each
fund to become investors in a combined fund that has a larger asset size than
either fund alone without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to both funds and their shareholders.


                     BOARDS' EVALUATION AND RECOMMENDATION

     For the reasons described above, the Board of Trustees of your fund,
including the Independent Trustees, approved the Reorganization. In particular,
the Trustees determined that the Reorganization is in the best interest 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 Pioneer
Series Trust IV, including the Independent Trustees, approved the
Reorganization. They also determined that the Reorganization is in the best
interests of Pioneer Classic Balanced Fund and that the interests of Pioneer
Classic Balanced Fund's shareholders would not be diluted as a result of the
Reorganization.

     The Trustees of your fund recommend that shareholders of your fund vote
FOR the proposal to approve the Agreement and Plan of Reorganization.

                                 PROPOSAL 1(c)


                                    SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of
Agreement and Plan of Reorganization attached as Exhibit A, because they
contain details that are not in the summary.

     If Proposal 1(c) is approved, your fund will be reorganized into Pioneer
AMT-Free Municipal Fund, as described above.


     Each fund has similar investment objectives and investment strategies.
However, your fund is a non-diversified fund that invests primarily in Florida
municipal securities that are exempt from Florida intangible personal property
tax while Pioneer AMT-Free Municipal Fund is a diversified fund that invests in
a broader range of municipal securities than your fund and its shares are not
exempt from the Florida intangible personal property tax. In addition, your
fund may invest in securities the income from which is a tax preference item
for purposes of the federal alternative minimum tax while Pioneer AMT-Free
Municipal Fund offers the benefit of avoiding income which is a tax preference
item for non-corporate shareholders for purposes of the federal alternative
minimum tax. The table below provides a comparison of the two funds. In the
table below, if a row extends across the entire table, the policy disclosed
applies to both your fund and Pioneer AMT-Free Municipal Fund.

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

                           Each fund may invest up to 10% of its net assets in inverse floating rate obligations (a type of
                           derivative instrument). Inverse floating rate obligations represent interests in tax exempt bonds.
                           The interest rate on inverse floating rate obligations will generally decrease as short-term interest
                           rates increase, and increase as short-term rates decrease. Due to their leveraged structure, the
                           sensitivity of the market value of an inverse floating rate obligation to changes in interest rates
                           is generally greater than a comparable long term bond issued by the same municipality and with
                           similar credit quality, redemption and maturity provisions. Inverse floating rate obligations may be
                           volatile and involve leverage risk.

                           Each fund may invest up to 10% of its net assets in debt securities rated below investment grade
                           (including securities in default) or, if unrated, of equivalent quality as determined by Pioneer.
                           Debt securities rated below investment grade are commonly referred to as "junk bonds" and are
                           considered speculative. Below investment grade debt securities involve greater risk of loss, are
                           subject to greater price volatility and are less liquid, especially during periods of economic
                           uncertainty or change, than higher quality debt securities.
- ------------------------------------------------------------------------------------------------------------------------------------
 Temporary defensive       Normally, each fund invests substantially all of its assets to meet its investment objective.
 strategies                Each fund may invest the remainder of its assets in securities with remaining maturities of
                           less than one year, cash equivalents or may hold cash. For temporary defensive purposes, including
                           during periods of unusual cash flows, each fund may depart from its principal investment strategies
                           and invest part or all of its assets in these securities or may hold cash. During such periods, a
                           fund may not be able to achieve its investment objective. Each fund intends to adopt a defensive
                           strategy when Pioneer believes securities in which the fund normally invests have extraordinary risks
                           due to political or economic factors and in other extraordinary circumstances.

- ------------------------------------------------------------------------------------------------------------------------------------
                        
 Short-term trading        Each fund usually does 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 shareowners to incur a higher level of taxable income or capital gains.
- ------------------------------------------------------------------------------------------------------------------------------------
Derivatives                Each fund may use futures and options on securities, indices 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, indices or other financial instruments. Although there is no specific
                           limitation on investing in derivatives, each fund does not use derivatives as a primary investment
                           technique and generally limits their use to hedging. However, each fund may use derivatives for a
                           variety of non-principal purposes, including:

                           o As a hedge against adverse changes in the market prices of securities or interest rates

                           o As a substitute for purchasing or selling securities

                           o To increase the fund's return as a non-hedging strategy that may be considered speculative

                           Even a small investment in derivatives can have a significant impact on the fund's exposure to the
                           market prices of securities or 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. The fund will only invest in derivatives to the extent Pioneer believes
                           these investments do not prevent the fund from seeking its investment objective.

                             your investment firm may receive a commission from Pioneer Funds Distributor, Inc. ("PFD"), the
                             funds' distributor, of up to 4% declining as the size of your investment increases.

                             net assets. These fees are paid out of a fund's assets on an ongoing basis. Over time these fees will

                             after five years. Your investment firm may receive a commission from PFD, the funds' distributor, at
                             the time of your purchase of up to 4%.

                           o Class B shares are subject to distribution and service (12b-1) fees of up to 1% of average daily

                             fees will increase the cost of investments and may cost more than other types of sales charges.

                           0.50% of the fund's average daily net assets on the first $250 million, 0.45% on assets greater than
                           $250 million to $750 million and 0.40% on assets greater than $750 million. The fee is accrued daily
                           and paid monthly.

                           A discussion regarding the basis for the Board of Trustees' approval of the management contract is

Buying shares              You may buy shares from any investment firm that has a sales agreement with PFD, the funds'
                           distributor. You can buy shares at the offering price. You may use securities you own to purchase
                           shares of the fund provided that Pioneer, in its sole discretion, determines that the securities are
                           consistent with the fund's objective and policies and their acquisition is in the best interests of
                           the fund.

                           If you have an existing non-retirement account, you may purchase shares of a fund by telephone or online.
                           Certain IRAs also may use the telephone purchase privilege.
- ------------------------------------------------------------------------------------------------------------------------------------
Minimum initial            Your initial investment must be at least $1,000 for Class A, Class B or Class C shares, and
investment                 $5,000,000 for Class Y shares. Additional investments must be at least $100 for Class A shares, $500
                           for Class B or Class C shares, and there is no minimum initial investment amount for Class Y 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.
- ------------------------------------------------------------------------------------------------------------------------------------
Maximum purchase amounts   Purchases of fund shares are limited to $49,999 for Class B shares and $999,999 for Class C shares.
                           There is no maximum purchase for Class A shares or Class Y shares. These limits are applied on a per

 Exchanging shares         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. Each fund allows you to exchange your shares at net
                           asset value without charging you either an initial or contingent deferred shares 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. An exchange generally is treated as a sale and a new purchase of shares for
                           federal income tax purposes.

                           After you establish an eligible fund account, you can exchange fund shares by telephone or online.
- ------------------------------------------------------------------------------------------------------------------------------------
Selling shares             Your shares will be sold at net asset value per share next calculated after a 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.

                           If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by
                           telephone or online. You may sell fund shares held in a retirement plan account by telephone only if
                           your account is an eligible IRA (tax penalties may apply).
- ------------------------------------------------------------------------------------------------------------------------------------
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).
- ------------------------------------------------------------------------------------------------------------------------------------
                           You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales
                           charge unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or
                           Class C shares, you may pay a contingent deferred sales charge depending on how long you have owned
                           your shares.
- ------------------------------------------------------------------------------------------------------------------------------------


Comparison of Principal Risks of Investing in the Funds


Principal risks for both funds

     Because each fund has similar investment objectives, investment strategies
and principal investments, the funds are subject to some of the same principal
risks. You could lose money on your investment or not make as much as if you
invested elsewhere if:

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

     o  The issuer of a security owned by the fund defaults on its obligation to
        pay principal and/or interest or has its credit rating downgraded

     o  New federal or state legislation adversely affects the tax-exempt status
        of securities held by the fund or the financial ability of
        municipalities to repay these obligations

     o  The issuer of a security owned by the fund may not be able to make
        timely payments because of a general economic downturn or increased
        governmental costs

     o  Pioneer is incorrect in its expectation of changes in interest rates or
        the credit quality of an issuer

     Although distributions of interest income from each fund's tax-exempt
securities are generally exempt from regular federal income tax, distributions
from other sources, including capital gain distributions and any gain on the
sale of your shares, are not. You should consult a tax adviser about state and
local taxes on your fund's distributions.

     Market segment risks. To the extent either fund emphasizes, from time to
time, investments in a market segment, the fund will be subject to a greater
degree to the risks particular to the industries in that segment, and may
experience greater market fluctuation, than a fund without the same focus. At
times, more than 25% of the Pioneer AMT-Free Municipal Fund's assets may be
invested in the same market segment.


                                       44


Principal risks of investing in Pioneer Florida Tax Free Income Fund

     Concentration risk. Because Pioneer Florida Tax Free Income Fund
concentrates its investments in a single state, there may be more fluctuation
in the value of its securities than is the case for mutual funds whose
portfolios are more geographically diverse. Because the fund invests primarily
in securities issued by Florida and its municipalities, it is more vulnerable
to unfavorable developments in Florida than are funds that invest in municipal
securities of many states. Unfavorable developments in any economic sector may
adversely affect the overall Florida municipal market.


     Non-diversification risk. Pioneer Florida Tax Free Income Fund is not
diversified, which means that it can invest a higher percentage of its assets
in any one issuer than a diversified fund. Being non-diversified may magnify
the fund's losses from adverse events affecting a particular issuer. Pioneer
Florida Tax Free Income Fund generally invests in a limited number of
securities and, as a result, the fund's performance may be more volatile than
the performance of funds holding more securities.



The Funds' Fees and Expenses

     Shareholders of both funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay
if you were to buy and hold shares of each fund. The expenses in the tables
appearing below are based on (i) for your fund, the expenses of your fund for
the twelve-month period ended January 31, 2006, and (ii) for Pioneer AMT-Free
Municipal Fund, the expenses of Pioneer AMT-Free Municipal Fund for the
twelve-month period ended December 31, 2005. Future expenses for all share
classes may be greater or less. The tables also show the pro forma expenses of
the combined fund assuming the Reorganization occurred on December 31, 2005.

     The hypothetical examples below help you compare the cost of investing in
each fund. It assumes that: (a) you invest $10,000 in each fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each fund's operating expenses remain
the same and (e) Pioneer's contractual expense limitation for the combined
Pioneer AMT-Free Municipal Fund's Class A shares is in effect for year one. Pro
forma expenses are included assuming a Reorganization with your fund and
Pioneer AMT-Free Municipal Fund. The examples are for comparison purposes only
and are not a representation of either fund's actual expenses or returns,
either past or future.

(1)  Purchases of $1 million or more and purchases by participants in certain
     group plans are not subject to an initial sales charge but may be subject
     to a contingent deferred sales charge of 1%.

(2)  The funds' total annual operating expenses in the table have not been
     reduced by any expense offset arrangements.

(3)  The expenses in the table above reflect the expense limitations currently
     in effect under which Pioneer has contractually agreed not to impose all or
     a portion of its management fee and, if necessary, to limit other ordinary
     operating expenses to the extent required to reduce fund expenses to 0.82%,
     1.72% and 1.72% of the average daily net assets attributable to Class A,
     Class B and Class C shares, respectively. These expense limitations are in
     effect through December 1, 2008 for Class A shares and through December 1,
     2007 for Class B and Class C shares. There can be no assurance that Pioneer
     will extend the expense limitations beyond such time.

(4)  The expenses in the table above reflect the expense limitations currently
     in effect under which Pioneer has contractually agreed not to impose all or
     a portion of its management fee and, if necessary, to limit other ordinary
     operating expenses to the extent required to reduce fund expenses to 0.87%,
     1.77% and 1.77% of the average daily net assets attributable to Class A,
     Class B and Class C shares, respectively. These expense limitations are in
     effect through May 1, 2007 for Class A, Class B and Class C shares. There
     can be no assurance that Pioneer will extend the expense limitations beyond
     such time.

(5)  Net expenses in the table reflect the expense limitation that will be in
     effect upon the closing of the Reorganization, under which Pioneer has
     contractually agreed not to impose all or a portion of its management fee
     and, if necessary, to limit other ordinary operating expenses to the extent
     required to reduce fund expenses to 0.82% of the average daily net assets
     attributable to Class A shares. This expense limitation is in effect from
     the closing date of the Reorganization through May 1, 2008. There can be no
     assurance that Pioneer will extend the expense limitation beyond such time.

Comparison of Fund Performance

     The bar charts show the year-by-year performance of each fund's Class A
shares since inception. Class B, Class C, Class Y and Investor Class shares
will have different performance. The chart does not reflect any sales charge
you may pay when you buy or sell fund shares. Any sales charge will reduce your
return. The tables show average annual total return (before and after sales
taxes) for each fund over time for each class of shares (including deductions
for sales charges) compared with a broad-based securities market index. The
after-tax returns shown for each fund are for Class A only; after-tax returns
for other classes will vary. Past performance (before and after taxes) does not
indicate future results.

     Pursuant to an agreement and plan of reorganization, Pioneer Florida Tax
Free Income Fund acquired the assets and liabilities of AmSouth Florida
Tax-Exempt Fund (the predecessor fund) on September 23, 2005. In the
reorganization, the predecessor fund exchanged all of its assets for shares of
the fund. The predecessor fund offered classes of shares similar to the fund's
Class A, Class B and Class Y shares. As a result of the reorganization, the
fund is the accounting successor of the predecessor fund. The performance of
the Class A, Class B and Class Y shares of the fund includes the performance of
the predecessor fund's Class A, Class B and Class I shares prior to the
Reorganization, which has been restated to reflect differences in any
applicable sales charges (but not differences in expenses). Class C shares were
not previously offered by the predecessor fund. The performance of the fund's
Class C shares set forth in the table below is based upon the performance of
the predecessor fund's Class B shares as adjusted to reflect sales charges
applicable to the fund's Class C shares (but not other differences in
expenses). If the performance had been adjusted to reflect all differences in
expenses, the performance of the fund would be lower.

* During the period shown in the bar chart, Pioneer Florida Tax Free Income
  Fund's highest quarterly return was 3.89% for the quarter ended September
  30, 2002 and the lowest quarterly return was (2.12)% for the quarter ended
  June 30, 2004. For the period from January 1, 2006 to June 30, 2006, Pioneer
  Florida Tax Free Income Fund's return was (0.07%).

     Pioneer AMT-Free Municipal Fund acquired the assets and liabilities of
Safeco Municipal Bond Fund (the predecessor fund) on December 10, 2004. In the
reorganization, the predecessor fund exchanged its assets for Investor Class
shares of the fund. As a result of the reorganization, the fund is the
accounting successor of the predecessor fund. The fund's Investor Class shares
are not offered through this prospectus. The performance of Class A, Class B
and Class C shares of Pioneer AMT-Free Municipal Fund includes the net asset
value performance of the predecessor fund's Class A, Class B and Class C shares
prior to the reorganization, which has been restated to reflect differences in
any applicable sales charges (but not differences in expenses). If all the
expenses of the Pioneer fund were reflected, the performance would be lower.

     The following table sets forth the capitalization of each fund as of May
31, 2006 and the pro forma combined capitalization of both funds as if the
Reorganization had occurred on that date. If the Reorganization is consummated,
the actual exchange ratios on the Closing Date may vary from the exchange
ratios indicated. This is due to changes in the market value of the portfolio
securities of both funds between May 31, 2006 and the Closing Date, changes in
the amount of undistributed net investment income and net realized capital
gains of both funds during that period resulting from income and distributions,
and changes in the accrued liabilities of both funds during the same period.

         PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION

The Reorganization


     o  The Reorganization is scheduled to occur as of the close of business on
        November 10, 2006, but may occur on such later date as the parties may
        agree in writing. Your fund will transfer all of its assets to Pioneer
        AMT-Free Municipal Fund, and Pioneer AMT-Free Municipal Fund will assume
        all of your fund's liabilities. This will result in the addition of your
        fund's assets to Pioneer AMT-Free Municipal Fund's portfolio. The net
        asset value of both funds will be computed as of the close of regular
        trading on the New York Stock Exchange on the Closing Date.


     o  Pioneer AMT-Free Municipal Fund will issue to your fund Class A shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class A shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class A shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class A shareholders of your fund will end up as Class A
        shareholders of Pioneer AMT-Free Municipal Fund.

     o  Pioneer AMT-Free Municipal Fund will issue to your fund Class B shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class B shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class B shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class B shareholders of your fund will end up as Class B
        shareholders of Pioneer AMT-Free Municipal Fund.

     o  Pioneer AMT-Free Municipal Fund will issue to your fund Class C shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class C shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class C shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class C shareholders of your fund will end up as Class C
        shareholders of Pioneer AMT-Free Municipal Fund.

     o  Pioneer AMT-Free Municipal Fund will issue to your fund Class Y shares
        with an aggregate net asset value equal to the net assets attributable
        to your fund's Class Y shares. As part of the liquidation of your fund,
        these shares will immediately be distributed to Class Y shareholders of
        record of your fund in proportion to their holdings on the Closing Date.
        As a result, Class Y shareholders of your fund will end up as Class Y
        shareholders of Pioneer AMT-Free Municipal Fund.

     o After the shares are issued, your fund will be dissolved.

Agreement and Plan of Reorganization

     The shareholders of your fund are being asked to approve the Agreement, the
form of which is attached to this Proxy Statement/Prospectus as Exhibit A and
incorporated herein by this reference. The description of the Agreement
contained herein, which include all the material provisions of the Agreement, is
qualified in its entirety by the attached copy.

Reasons for the Proposed Reorganization

     The Trustees of your fund believe that the proposed Reorganization will be
advantageous to the shareholders of your fund for several reasons. The Trustees
considered the following matters, among others, in approving the proposal.

     First, the Reorganization would eliminate confusion in the marketplace
caused by having two substantially similar funds and enhancing the potential
for one of the two funds to achieve growth in assets. The combined fund may be
better positioned to attract assets than your fund. After the Reorganization,
the combined fund's greater asset size may allow it, relative to your fund, to
(i) obtain better net prices on securities trades, and (ii) reduce per share
expenses as fixed expenses are shared over a larger asset base.


     Second, the long-term historical investment performance of Pioneer
AMT-Free Municipal Fund is higher than your fund. For the one and five year
periods ended December 31, 2005, Class A shares of Pioneer AMT-Free Municipal
Fund had average annual total returns of 0.07% (one year) and 5.17% (five
year), compared to average annual total returns of the Class A shares of
Pioneer Florida Tax Free Income Fund of -3.59% (one year) and 2.66% (five
year), during the same periods.

     Third, since the management fee rate is the same for both funds, there
will be no increase in management fee (as a percentage of average daily net
assets) as a result of the Reorganization. The Reorganization would however
result in Pioneer AMT-Free Municipal Fund's assets exceeding the second
breakpoint level ($500 million) in the fund's management fee schedule. If
assets were to continue to grow the effective rate of the combined fund's
management fee will be reduced as a result. With the exception of Class A
shares, the historical total expenses of Pioneer AMT-Free Municipal Fund's
shares are lower than Pioneer Florida Tax Free Income Fund's historical total
expenses for its shares. In addition, it is anticipated that the pro forma
expense ratio for each class of shares will be the same or lower than the



                                       51


historical expense ratio of Pioneer Florida Tax Free Income Fund after the
Reorganization and has the potential to decrease further with asset growth.
Pioneer has agreed not to impose all or a portion of its management fee and, if
necessary, to limit other ordinary operating expenses to the extent required to
limit Pioneer AMT-Free Municipal Fund's Class A shares to 0.82% of the average
daily net assets attributable to Class A shares through May 1, 2008.


     Fourth, the Board was presented with information and considered that
Pioneer AMT-Free Municipal Fund's shares are not exempt from the Florida state
intangible personal property tax. However, the Board also considered the fact
that Pioneer AMT-Free Municipal Fund offers the benefit of not investing in any
securities the income from which is a preference item for purposes of the
alternative minimum tax, whereas Pioneer Florida Tax Free Income Fund may
invest up to 20% of its assets in such securities.


     The Boards of both funds considered that each fund would bear equally half
of all of the expenses associated with the preparation, printing and mailing of
any shareholder communications, including this Proxy Statement/Prospectus, and
any filings with the SEC and other governmental agencies in connection with the
Reorganization. Pioneer will bear the balance of these expenses. The Boards of
both funds estimate that these expenses in the aggregate will not exceed
$46,500.

     The Boards of both funds considered that the funds' investment adviser and
principal distributor would benefit from the Reorganization. For example,
Pioneer might achieve cost savings from managing one larger fund compared to
managing more than one fund with similar investment strategies, which would
result in a decrease in the combined fund's gross expenses and a corresponding
decrease in fees waived under the current expense limit agreement. The Boards
believe, however, that these savings will not amount to a significant economic
benefit to Pioneer or the principal distributor.

     The Boards of Trustees of both funds also considered that the
Reorganization presents an excellent opportunity for the shareholders of each
fund to become investors in a combined fund that has a larger asset size than
either fund alone without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to both funds and their shareholders.

                     BOARDS' EVALUATION AND RECOMMENDATION

     For the reasons described above, the Board of Trustees of your fund,
including the Independent Trustees, approved the Reorganization. In particular,
the Trustees determined that the Reorganization is in the best interest 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 Pioneer
Series Trust II, including the Independent Trustees, approved the

                                    SUMMARY

     The following is a summary of more complete information appearing later in
this Proxy Statement/Prospectus or incorporated herein. You should read
carefully the entire Proxy Statement/Prospectus, including the form of
Agreement and Plan of Reorganization attached as Exhibit A, because they
contain details that are not in the summary.

     If Proposal 1(d) is approved, your fund will be reorganized into Pioneer
Research Fund, as described above.

     Although each fund has the same investment objective, your fund is a
non-diversified fund that may invest a significant portion of its assets in
equity securities of mid- and large-cap companies, as well as a greater portion
of its assets in non-U.S. securities, than Pioneer Research Fund. Pioneer
Research Fund is a diversified fund that invests primarily in equity securities
of U.S. issuers. The table below provides a comparison of the two funds. In the
table below, if a row extends across the entire table, the policy disclosed
applies to both your fund and Pioneer Research Fund.

- ------------------------------------------------------------------------------------------------------------------------------------
Temporary defensive    Normally, each fund invests substantially all of its assets to meet its investment objective. Each
strategies             fund may invest the remainder of its assets in securities with remaining maturities of less than
                       one year, cash equivalents or may hold cash. For temporary defensive purposes, including
                       during periods of unusual cash flows, each fund may depart from its principal investment
                       strategies and invest part or all of its assets in these securities or may hold cash. During such
                       periods, a fund may not be able to achieve its investment objective. Each fund intends to adopt
                       a defensive strategy when Pioneer (or the subadviser, as the case may be) believes securities in
                       which the fund normally invests have extraordinary risks due to political or economic factors
                       and in other extraordinary circumstances.
- ------------------------------------------------------------------------------------------------------------------------------------
Short-term trading     Each fund usually does 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 shareowners to incur a higher level of
                       taxable income or capital gains.

Derivatives            Each fund may use futures and options on securities, indices and currencies, forward foreign currency
                       exchange contracts 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. Although there is no specific limitation on investing in
                       derivatives, each fund does not use derivatives as a primary investment technique and generally limits
                       their use to hedging. However, each fund may use derivatives for a variety of non-principal purposes,
                       including:

                       o As a hedge against adverse changes in market prices of securities, interest rates or currency exchange
                         rates

                       o As a substitute for purchasing or selling securities

                       o To increase the fund's return as a non-hedging strategy that may be considered speculative

                       Even a small investment in derivatives can have a significant impact on the funds' exposure to the market
                       prices of securities, interest rates or currency exchange rates. If changes in a derivative's value do
                       not correspond to changes in the value of the funds' other investments, the funds 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. The funds will only invest in derivatives to the extent Pioneer (or
                       the subadviser, as the case may be) believes these investments do not prevent the funds from seeking
                       their investment objective.

                       You can buy shares at the offering price. You may use securities you own to purchase shares of the fund
                       provided that Pioneer, in its sole discretion, determines that the securities are consistent with the
                       fund's objective and policies and their acquisition is in the best interests of the fund.

                       If you have an existing non-retirement account, you may purchase shares of a fund by telephone or online.
                       Certain IRAs also may use the telephone purchase privilege.

Minimum initial        Your initial investment must be at least $1,000 for Class A, Class B or Class C shares, and investment
                       $5,000,000 for Class Y shares. Additional investments must be at least $100 for Class A shares, $500 for
                       Class B or Class C shares, and there is no minimum initial investment amount for Class Y shares. You may
                       qualify for lower initial or subsequent investment minimums if you are opening a retirement plan account,

Exchanging shares      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. Each fund allows you to exchange your shares at net asset value
                       without charging you either an initial or contingent deferred shares 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. An exchange
                       generally is treated as a sale and a new purchase of shares for federal income tax purposes.

                       After you establish an eligible fund account, you can exchange fund shares by telephone or online.
- ------------------------------------------------------------------------------------------------------------------------------------
Selling shares         Your shares will be sold at net asset value per share next calculated after a 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.

                       If you have an eligible non-retirement account, you may sell up to $100,000 per account per day by
                       telephone or online. You may sell fund shares held in a retirement plan account by telephone only if your
                       account is an eligible IRA (tax penalties may apply).
- ------------------------------------------------------------------------------------------------------------------------------------
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).
- ------------------------------------------------------------------------------------------------------------------------------------
                       You buy or sell shares at the share price. When you buy Class A shares, you pay an initial sales charge
                       unless you qualify for a waiver or reduced sales charge. When you sell Class A, Class B or Class C
                       shares, you may pay a contingent deferred sales charge depending on how long you have owned your shares.

     Because each fund has the same investment objective and similar investment
policies and strategies, the funds are subject to some of the same principal
risks. You could lose money on your investment or not make as much as if you
invested elsewhere if:

     o  The stock market goes down or performs poorly relative to other
        investments (this risk may be greater in the short term)

     o  Value stocks fall out of favor with investors

     o  Pioneer Focused Equity Fund does not have the growth potential
        originally expected

     o  Pioneer Research Fund's investments remain undervalued or do not have
        the potential value originally expected

     Market segment risks. To the extent either fund emphasizes, from time to
time, investments in a market segment, the fund will be subject to a greater
degree to the risks particular to the industries in that segment, and may
experience greater market fluctuation, than a fund without the same focus. For
example, industries in the financial segment, such as banks, insurance
companies, broker-dealers and REITs, may be sensitive to changes in interest
rates and general economic activity and are subject to extensive government
regulation. Industries in the technology segment, such as information
technology, communications equipment, computer hardware and software, and
office and scientific equipment, are subject to risks of rapidly evolving
technology, short product lives, rates of corporate expenditures, falling
prices and profits, competition from new market entrants, and general economic
conditions.

     Non-U.S. securities risks. Each fund is also subject to risks associated
with investments other than U.S. equity securities. Pioneer Focused Equity Fund
may invest in non-U.S. securities to a greater degree than Pioneer Research
Fund. Investing in non-U.S. issuers may involve unique risks compared to
investing in securities of U.S. issuers. Some of these risks do not apply to
larger, more developed non-U.S. countries. However, these risks are more
pronounced for issuers of securities in emerging markets. These risks may
include:

     o  Less information about non-U.S. issuers or markets may be available due
        to less rigorous disclosure or accounting standards or regulatory
        practices


                                       59


     o  Many non-U.S. markets are smaller, less liquid and more volatile. In a
        changing market, Pioneer may not be able to sell the fund's portfolio
        securities at times, in amounts and at prices it considers reasonable

     o  Adverse effect of currency exchange rates or controls on the value of
        the fund's investments

     o  The economies of non-U.S. countries may grow at slower rates than
        expected or may experience a downturn or recession

     o  Economic, political and social developments may adversely affect the
        securities markets

     o  Withholding and other non-U.S. taxes may decrease the fund's return

     Non-diversification risk (Pioneer Focused Equity Fund). Pioneer Focused
Equity Fund is not diversified, which means that it can invest a higher
percentage of its assets in any one issuer than a diversified fund. Being
non-diversified may magnify the fund's losses from adverse events affecting a
particular issuer. The fund generally invests in a limited number of securities
and, as a result, the fund's performance may be more volatile than the
performance of funds holding more securities.

The Funds' Fees and Expenses

     Shareholders of both funds pay various fees and expenses, either directly
or indirectly. The tables below show the fees and expenses that you would pay
if you were to buy and hold shares of each fund. The expenses in the tables
appearing below are based on (i) for your fund, the expenses of your fund for
the twelve-month period ended January 31, 2006, and (ii) for Pioneer Research
Fund, the expenses of Pioneer Research Fund for the twelve-month period ended
December 31, 2005. Future expenses for all share classes may be greater or
less. The tables also show the pro forma expenses of the combined fund assuming
the Reorganization occurred on December 31, 2005.

     The hypothetical examples below help you compare the cost of investing in
each fund. It assumes that: (a) you invest $10,000 in each fund for the time
periods shown, (b) you reinvest all dividends and distributions, (c) your
investment has a 5% return each year, (d) each fund's operating expenses remain
the same and (e) Pioneer's contractual expense limitation for the combined
Pioneer Research Fund's Class A, Class B and Class C shares is in effect for
year one. Pro forma expenses are included assuming a Reorganization with your
fund and Pioneer Research Fund. The examples are for comparison purposes only
and are not a representation of either fund's actual expenses or returns,
either past or future.

(1)  Purchases of $1 million or more and purchases by participants in certain
     group plans are not subject to an initial sales charge but may be subject
     to a contingent deferred sales charge of 1%.

(2)  The funds' total annual operating expenses in the table have not been
     reduced by any expense offset arrangements.


(3)  The expenses in the table above reflect the expense limitations currently
     in effect under which Pioneer has contractually agreed not to impose all or
     a portion of its management fee and, if necessary, to limit other ordinary
     operating expenses to the extent required to reduce fund expenses to 1.25%,
     2.15% and 2.15% of the average daily net assets attributable to Class A,
     Class B and Class C shares, respectively. These expense limitations are in
     effect through May 1, 2009 for Class A shares and through May 1, 2007 for
     Class B and Class C shares. There can be no assurance that Pioneer will
     extend the expense limitations beyond such time.

(4)  Net expenses in the table reflect the expense limitations that will be in
     effect upon the closing of the Reorganization, under which Pioneer has
     contractually agreed not to impose all or a portion of its management fee
     and, if necessary, to limit other ordinary operating expenses to the extent
     required to reduce fund expenses to 1.25%, 2.15% and 2.15% of the average
     daily net assets attributable to Class A, Class B and Class C shares,
     respectively. These expense limitations are in effect from the closing date
     of the Reorganization through May 1, 2009 for Class A shares and through
     May 1, 2008 for Class B and Class C shares. There can be no assurance that
     Pioneer will extend the expense limitations beyond such time.


Comparison of Fund Performance

     The bar charts show the year-by-year performance of each fund's Class A
shares since inception. Class B, Class C and Class Y shares will have different
performance. The chart does not reflect any sales charge you may pay when you
buy or sell fund shares. Any sales charge will reduce your return. The tables
show average annual total return (before and after sales taxes) for each fund
over time for each class of shares (including deductions for sales charges)
compared with a broad-based securities market index. The after-tax returns
shown for each fund are for Class A only; after-tax returns for other classes
will vary. Past performance (before and after taxes) does not indicate future
results.

     Pursuant to an agreement and plan of reorganization, Pioneer Focused
Equity Fund acquired the assets and liabilities of AmSouth Select Equity Fund
(the predecessor fund) on September 23, 2005. In the reorganization, the
predecessor fund exchanged all of its assets for shares of the fund. The
predecessor fund offered classes of shares similar to the fund's Class A, Class
B and Class Y shares. As a result of the reorganization, the fund is the
accounting successor of the predecessor fund. The performance of the Class A,
Class B and


                                       62


Class Y shares of the fund includes the performance of the predecessor fund's
Class A, Class B and Class I shares prior to the Reorganization, which has been
restated to reflect differences in any applicable sales charges (but not
differences in expenses). Class C shares were not previously offered by the
predecessor fund. The performance of the fund's Class C shares set forth in the
table below is based upon the performance of the predecessor fund's Class B
shares as adjusted to reflect sales charges applicable to the fund's Class C
shares (but not other differences in expenses). If the performance had been
adjusted to reflect all differences in expenses, the performance of the fund
would be lower.

(1) After-tax returns are calculated using the historical highest individual
    federal marginal income tax rates and do not reflect the impact of state and
    local taxes. Actual after-tax returns depend on the investor's tax situation
    and may differ from those shown. Furthermore, the after-tax returns shown
    are not relevant to shareholders who hold fund shares through tax-deferred
    arrangements such as 401(k) plans or individual retirement accounts.
    After-tax returns for Class B and Class C shares will vary from the
    after-tax returns presented for Class A shares.

(2) The performance of Class C shares does not reflect the 1% front-end sales
    charge in effect prior to February 1, 2004. If you paid a 1% sales charge,
    your returns would be lower than those shown above.

    C shares). The fund began offering its Class C shares on September 23, 2005.

     The following table sets forth the capitalization of each fund as of May
31, 2006 and the pro forma combined capitalization of both funds as if the
Reorganization had occurred on that date. If the Reorganization is consummated,
the actual exchange ratios on the Closing Date may vary from the exchange
ratios indicated. This is due to changes in the market value of the portfolio
securities of both funds between May 31, 2006 and the Closing Date, changes in
the amount of undistributed net investment income and net realized capital
gains of both funds during that period resulting from income and distributions,
and changes in the accrued liabilities of both funds during the same period.

         PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION


The Reorganization


     o  The Reorganization is scheduled to occur as of the close of business on
        November 10, 2006, but may occur on such later date as the parties may
        agree in writing. Your fund will transfer all of its assets to Pioneer
        Research Fund, and Pioneer Research Fund will assume all of your fund's
        liabilities. This will result in the addition of your fund's assets to
        Pioneer Research Fund's portfolio. The net asset value of both funds
        will be computed as of the close of regular trading on the New York
        Stock Exchange on the Closing Date.


     o  Pioneer Research Fund will issue to your fund Class A shares with an
        aggregate net asset value equal to the net assets attributable to your
        fund's Class A shares. As part of the liquidation of your fund, these
        shares will immediately be distributed to Class A shareholders of record
        of your fund in proportion to their holdings on the Closing Date. As a
        result, Class A shareholders of your fund will end up as Class A
        shareholders of Pioneer Research Fund.

     o  Pioneer Research Fund will issue to your fund Class B shares with an
        aggregate net asset value equal to the net assets attributable to your
        fund's Class B shares. As part of the liquidation of your fund, these
        shares will immediately be distributed to Class B shareholders of record
        of your fund in proportion to their holdings on the Closing Date. As a
        result, Class B shareholders of your fund will end up as Class B
        shareholders of Pioneer Research Fund.

     o  Pioneer Research Fund will issue to your fund Class C shares with an
        aggregate net asset value equal to the net assets attributable to your
        fund's Class C shares. As part of the liquidation of your fund, these
        shares will immediately be distributed to Class C shareholders of record
        of your fund in proportion to their holdings on the Closing Date. As a
        result, Class C shareholders of your fund will end up as Class C
        shareholders of Pioneer Research Fund.


                                       65


     o  Pioneer Research Fund will issue to your fund Class Y shares with an
        aggregate net asset value equal to the net assets attributable to your
        fund's Class Y shares. As part of the liquidation of your fund, these
        shares will immediately be distributed to Class Y shareholders of record
        of your fund in proportion to their holdings on the Closing Date. As a
        result, Class Y shareholders of your fund will end up as Class Y
        shareholders of Pioneer Research Fund.

     o  After the shares are issued, your fund will be dissolved.

Agreement and Plan of Reorganization

     The shareholders of your fund are being asked to approve the Agreement and
Plan of Reorganization, the form of which is attached to this Proxy
Statement/Prospectus as Exhibit A and incorporated herein by this reference.
The description of the Agreement and Plan of Reorganization contained herein,
which include all the material provisions of the Agreement and Plan of
Reorganization, is qualified in its entirety by the attached copy.

Reasons for the Proposed Reorganization

     The Trustees of your fund believe that the proposed Reorganization will be
advantageous to the shareholders of your fund for several reasons. The Trustees
considered the following matters, among others, in approving the proposal.

     First, the Reorganization would eliminate confusion in the marketplace
caused by having two substantially similar funds and enhancing the potential
for one of the two funds to achieve growth in assets. The combined fund may be
better positioned to attract assets than your fund. After the Reorganization,
the combined fund's greater asset size may allow it, relative to your fund, to
(i) obtain better net prices on securities trades, and (ii) reduce per share
expenses as fixed expenses are shared over a larger asset base.


     Second, while Pioneer Research Fund's longer term performance was lower
than your fund's performance, Pioneer Research Fund's Class A shares had higher
total returns than your fund during the two most recent calendar years. For the
one and five year periods ended December 31, 2005, Class A shares of Pioneer
Research Fund had average annual total returns of 1.03% (one year) and -1.34%
(five year), compared to average annual total returns of the Class A shares of
Pioneer Focused Equity Fund of -12.06% (one year) and 3.54% (five year), during
the same periods.

     Third, although your fund's management fee rate schedule is lower than
that of Pioneer Research Fund, Pioneer has agreed to reduce its management fee
rate upon the closing of the Reorganization for Pioneer Research Fund to equal
your fund's management fee rate. Although the total expenses of your fund's
shares are generally lower than Pioneer Research Fund's shares total expenses,
Pioneer has agreed not to impose all or a portion of its management fee and, if
necessary, to limit other ordinary operating expenses to the extent required to
reduce Pioneer Research Fund's expenses to 1.25%, 2.15% and 2.15% of the
average daily net assets attributable to Class A, Class B and Class C shares,
respectively. These expense limitations are in effect through May 1, 2009 for
Class A shares and through May 1, 2008 for Class B and Class C shares. Further,
the pro forma Class Y share expense ratio of the combined fund is expected to
be lower than the Class Y share expense ratio of your fund.


     The Boards of both funds considered that each fund would bear equally half
of all of the expenses of the funds associated with the preparation, printing
and mailing of any shareholder communications, including this Proxy
Statement/Prospectus, and any filings with the SEC and other governmental
agencies in connection with the Reorganization. Pioneer will bear the balance
of these expenses. The Boards of both funds estimate that these expenses in the
aggregate will not exceed $57,500.

     The Boards of both funds considered that the funds' investment adviser and
principal distributor would benefit from the Reorganization. For example,
Pioneer might achieve cost savings from managing one larger fund compared to
managing more than one fund with similar investment strategies, which would
result in a decrease in the combined fund's gross expenses and a corresponding
decrease in fees waived under the current expense limit agreement. The Boards
believe, however, that these savings will not amount to a significant economic
benefit to Pioneer or the principal distributor.

     The Boards of Trustees of both funds also considered that the
Reorganization presents an excellent opportunity for the shareholders of each
fund to become investors in a combined fund that has a larger asset size than
either fund alone without the obligation to pay commissions or other
transaction costs that a fund normally incurs when purchasing securities. This
opportunity provides an economic benefit to both funds and their shareholders.

                     BOARDS' EVALUATION AND RECOMMENDATION

     For the reasons described above, the Board of Trustees of your fund,
including the Independent Trustees, approved the Reorganization. In particular,
the Trustees determined that the Reorganization is in the best interest 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 Pioneer
Research Fund, including the Independent Trustees, approved the Reorganization.
They also determined that the Reorganization is in the best interests of
Pioneer Research Fund and that the interests of Pioneer Research Fund's
shareholders would not be diluted as a result of the Reorganization.

     The Trustees of your fund recommend that shareholders of your fund vote
FOR the proposal to approve the Agreement and Plan of Reorganization.

              TERMS OF EACH AGREEMENT AND PLAN OF REORGANIZATION

The Reorganizations


     o  Each Reorganization is scheduled to occur as of the close of business on
        November 10, 2006, but may occur on such later date as the parties may
        agree to in writing. Your fund will transfer all of its assets to the
        corresponding Pioneer Fund. The corresponding Pioneer Fund will assume
        all of your fund's liabilities. The net asset value of both funds will
        be computed as of the close of regular trading on the New York Stock
        Exchange on the reorganization date.


     o  The corresponding Pioneer Fund will issue classes of shares to your fund
        with an aggregate net asset value equal to the net assets attributable
        to your fund's corresponding classes of shares. These shares will
        immediately be distributed to your fund's shareholders in proportion to
        the relative net asset value of their holdings of your fund's shares on
        the Closing Date. As a result, your fund's shareholders will end up as
        shareholders of the relevant class of the corresponding Pioneer Fund.

     o  After the shares are issued, your fund will be dissolved.

     o  Each Reorganization is intended to result in no income, gain or loss for
        federal income tax purposes to the corresponding Pioneer Fund, your fund
        or the shareholders of your fund and will not take place unless both
        Pioneer Funds involved in the Reorganization receive a satisfactory
        opinion concerning the tax consequences of the Reorganization from
        Wilmer Cutler Pickering Hale and Dorr LLP, counsel to the Pioneer Funds.

Agreement and Plan of Reorganization

     The shareholders of your fund are being asked to approve an Agreement and
Plan of Reorganization, the form of which is attached as Exhibit A to this
Proxy Statement/Prospectus and incorporated herein by this reference. The
description of the Agreement and Plan of Reorganization contained herein, which
includes the material provisions of the Agreement and Plan of Reorganization,
is qualified in its entirety by the attached copy.

     Cancellation of Share Certificates. If your shares are represented by one
or more share certificates before the Closing Date, on the Closing Date all
certificates will be canceled, will no longer evidence ownership of your fund's
shares and will evidence ownership of the corresponding Pioneer Fund shares.
The corresponding Pioneer 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 the corresponding Pioneer Fund of all
its obligations under the Agreement and Plan of Reorganization and the receipt
of all consents, orders and permits necessary to consummate the Reorganization
(see Agreement and Plan of Reorganization, Section 6).

     The obligation of the corresponding Pioneer 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 and Plan
of Reorganization, 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 and Plan of Reorganization,
Section 7).

     The obligations of your fund and the corresponding Pioneer Fund are
subject to approval of the Agreement and Plan of Reorganization 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 Wilmer
Cutler Pickering Hale and Dorr LLP as to the federal income tax consequences of
the Reorganization (see Agreement and Plan of Reorganization, Section 8.5).

     Termination of Agreement and Plan of Reorganization. The Board of Trustees
of your fund or the corresponding Pioneer Fund may terminate the Agreement and
Plan of Reorganization (even if the shareholders of your fund have already
approved it) by their mutual agreement at any time before the Closing Date, if
the Boards believe that proceeding with the Reorganization would no longer be
advisable.

     Expenses of the Reorganization. The funds will bear equally half of all
the expenses of both funds incurred in connection with the Reorganization,
including the costs of printing, mailing, legal fees, audit fees and
solicitation expenses. Pioneer will bear the balance of these expenses.


                                       68


                       TAX STATUS OF EACH REORGANIZATION

     Each Reorganization will not result in income, gain or loss for U.S.
federal income tax purposes and will not take place unless the funds receive a
satisfactory opinion from Wilmer Cutler Pickering Hale and Dorr LLP, counsel to
the funds, that the Reorganization will be a "reorganization" within the
meaning of Section 368(a) of the Code.

     As a result, for federal income tax purposes:

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

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

     o  The basis of the assets of your fund acquired by the corresponding
        Pioneer Fund will be the same as the basis of those assets in the hands
        of your fund immediately before the transfer;

     o  The tax holding period of the assets of your fund in the hands of the
        corresponding Pioneer Fund will include your fund's tax holding period
        for those assets;

     o  You will not recognize gain or loss upon the exchange of your shares of
        your fund solely for the corresponding Pioneer Fund shares as part of
        the Reorganization;

     o  The basis of the corresponding Pioneer Fund shares received by you in
        the Reorganization will be the same as the basis of the shares of your
        fund you surrender in exchange; and

     o  The tax holding period of the corresponding Pioneer Fund shares you
        receive will include the tax holding period of the shares of your fund
        that you surrender in exchange, provided that the shares of your fund
        were held by you as capital assets on the date of the exchange.

     In rendering such opinion, counsel shall rely upon, among other things,
reasonable assumptions as well as representations of the corresponding Pioneer
Fund and your fund.

     No tax ruling has been or will be received from the Internal Revenue
Service ("IRS") in connection with the Reorganization. An opinion of counsel is
not binding on the IRS or a court, and no assurance can be given that the IRS
would not assert, or a court would not sustain, a contrary position.

     The foregoing consequences may not apply to certain classes of taxpayers
who are subject to special circumstances, such as shareholders who are not
citizens of or residents of the United States, insurance companies, tax-exempt
organizations, financial institutions, dealers in securities or foreign
currencies, or persons who hold their shares as part of a straddle or
conversion transaction. You should consult your tax adviser for the particular
tax consequences to you of the transaction, including the applicability of any
state, local or foreign tax laws.

                        VOTING RIGHTS AND REQUIRED VOTE

     Each share of your fund is entitled to one vote. A quorum is required to
conduct business at the meeting. With respect to your fund, the presence in
person or by proxy of a majority of the shares entitled to cast votes at the
meeting will constitute a quorum. A favorable vote of a "majority of the
outstanding voting securities" of your fund is required to approve the proposal
with respect to your fund. For this purpose, a "majority of the outstanding
shares of your fund" means the affirmative vote of the lesser of:

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

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


                                       69


     The table below shows how shares will be treated for the purposes of
quorum and voting requirements.

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


     If the required approval of shareholders is not obtained, the meeting may
be adjourned as more fully described in this Proxy Statement/
Prospectus, and 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.

    COMPARISON OF MASSACHUSETTS BUSINESS TRUST AND DELAWARE STATUTORY TRUST

     As described in Proposal 1(a), it is proposed that Pioneer America Income
Trust be reorganized into Pioneer Government Income Fund. Pioneer America Income
Trust is a Massachusetts business trust. Pioneer Government Income Fund, like
all of the other Pioneer Funds described in this Proxy Statement/Prospectus, is
a Delaware statutory trust (or series thereof). The following is a summary of
the principal differences between Massachusetts business trusts and Delaware
statutory trusts.

Limitation of Shareholders' and Series' Liability

     Delaware law provides that the shareholders of a Delaware statutory trust
shall not be subject to liability for the debts or obligations of the trust.
Under Massachusetts law, shareholders of a Massachusetts business trust may,
under certain circumstances, be liability 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, Delaware law affords grater protection against potential shareholder
liability. Similarly, Delaware law provides that, to the extent that a Delaware
statutory 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 a Massachusetts business trust. While the
trustees believe that a series of 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 statutory trust or a shareholder thereof) for any
act, omission or obligation of the statutory trust or any trustee thereof.
Delaware law also provides that a trustee's actions under a Delaware statutory
trust's declaration of trust or by-laws will not subject the trustee to
liability to the statutory trust or its shareholders if the trustee takes such
action in good faith reliance on the provisions of the statutory trust's
declaration of trust or bylaws. The declaration of trust of a Massachusetts
business trust may limit the liability of a trustee, who is not also an officer
of the corporation, 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. The trustees
believe that such limitations on liability under Delaware law and under the
Pioneer Funds' declarations of trust are consistent with those applicable to
directors of a corporation under Delaware law and will be beneficial in
attracting and retaining in the future qualified persons to act as trustees.


                                       70


Shareholder Voting

     Delaware law provides that a Delaware statutory 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
1940 Act, votes on certain matters by trustees would still need to be taken at
actual in-person meetings.

Board Composition

     Delaware law explicitly provides that separate boards of trustees may be
authorized for each series of a Delaware statutory trust. Whether separate
boards of trustees can be authorized for series of a Massachusetts business
trust is unclear under Massachusetts law. As always, the establishment of any
board of trustees of a registered investment company must comply with
applicable securities laws, including the provision of the 1940 Act regarding
the election of trustees by shareholders. Establishing separate boards of
trustees would, among other things, enable the series of a Delaware statutory
trust to be governed by individuals who are more familiar with such series'
particular operations.

                ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS

Investment Adviser

     Pioneer serves as the investment adviser to each Pioneer Fund. Pioneer
oversees each fund's operations and is responsible for the day-to-day
management of the fund's portfolio. In the case of Pioneer Focused Equity Fund,
Pioneer supervises the fund's subadviser, who is responsible for the day-to-day
management of the fund's portfolio. Pioneer is an indirect, wholly owned
subsidiary of UniCredito Italiano S.p.A., one of the largest banking groups in
Italy. Pioneer is part of the global asset management group providing
investment management and financial services to mutual funds, institutional and
other clients. As of March 31, 2006, assets under management were approximately
$199.3 billion worldwide, including over $50.5 billion in assets under
management by Pioneer. Pioneer's main office is at 60 State Street, Boston,
Massachusetts 02109. Pioneer's U.S. mutual fund investment history includes
creating one of the first mutual funds in 1928.

     The Board of Trustees of the Pioneer Funds is responsible for overseeing
the performance of Pioneer Funds' investment adviser and determining whether to
approve and renew a fund's investment management agreement.

Distributor and Transfer Agent

     PFD is the fund's distributor. Pioneer Investment Management Shareholder
Services, Inc. ("PIMSS") is the fund's transfer agent. The fund compensates PFD
and the transfer agent for their services. PFD and the transfer agent are
affiliates of Pioneer.

Disclosure of Portfolio Holdings

     The fund's policies and procedures with respect to the disclosure of the
fund's portfolio securities are described in the statement of additional
information and on Pioneer's website at www.pioneerinvestments.com.

Buying, Exchanging and Selling Shares of the Pioneer 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 using closing market
prices or readily available market quotations. When closing market prices or
market quotations are not available or are considered by Pioneer to be
unreliable, the fund uses a security's fair value. All methods of determining
the value of a security used by the fund, including those discussed below, on a
basis other than market value, are forms of fair value. All valuations of
securities on a fair value basis are made pursuant to procedures adopted by the
Board of Trustees. The use of fair value pricing by the fund may cause the net
asset value of its shares to differ from the net asset value that would be
calculated only using market prices. For market prices and quotations, as well
as for some fair value methods, the fund relies upon securities prices provided
by pricing services.


                                       71


     Each fund uses the fair value of a security, including a non-U.S.
security, when Pioneer determines that the closing market price on the primary
exchange where the security is traded no longer accurately reflects the value
of the security at the time the fund calculates its net asset value. This may
occur for a variety of reasons that affect either the relevant securities
markets generally or the specific issuer. For example, with respect to non-U.S.
securities held by the fund, developments relating to the securities market or
the specific issuer may occur between the time the primary market closes and
the time the fund determines its net asset value. In those circumstances, the
fund may use the fair value of the security. International securities markets
may be open on days when the U.S. markets are closed. For this reason, the
values of any international securities owned by the fund could change on a day
you cannot buy or sell shares of the fund.

     Certain types of securities, including those discussed in this paragraph,
are priced using fair value rather than market prices. Each fund uses a pricing
matrix to determine the value of fixed income securities that do not trade
daily. A pricing matrix is a means of valuing a debt security on the basis of
current market prices for other debt securities and historical trading patterns
in the market for fixed income securities. Each fund values cash equivalent
securities with remaining maturities of 60 days or less at amortized cost. To
the extent that a fund invests in the shares of other registered open-end
investment companies that are not traded on an exchange (mutual funds), such
shares are valued at their published net asset values per share as reported by
the funds. The prospectuses of these funds explain the circumstances under
which the funds will use fair value pricing and the effects of using fair value
pricing.

     Distribution and Service Plans. Each fund has adopted a distribution plan
for its Class A, Class B, Class C and Class R shares (if issued) in accordance
with Rule 12b-1 under the 1940 Act. Under each plan, the fund pays distribution
and service fees to PFD. Because these fees are an ongoing expense of the fund,
over time they increase the cost of your investment and your shares may cost
more than shares that are subject to other types of sales charges.

     Additional Payments to Financial Intermediaries. There are two principal
ways you compensate the financial intermediary through which you buy shares of
each fund--directly, by the payment of sales commissions, if any; and
indirectly, as a result of the fund paying Rule 12b-1 fees.

     Pioneer and its affiliates may make additional payments to your financial
intermediary. These payments by Pioneer may provide your financial intermediary
with an incentive to favor the Pioneer Funds over other mutual funds or assist
the distributor in its efforts to promote the sale of a fund's shares.
Financial intermediaries include broker-dealers, banks (including bank trust
departments), registered investment advisers, financial planners, retirement
plan administrators and other types of intermediaries.

     Pioneer makes these additional payments (sometimes referred to as "revenue
sharing") to financial intermediaries out of its own assets. Revenue sharing is
not an expense of the Pioneer Funds. Pioneer may base these payments on a
variety of criteria, including the amount of sales or assets attributable to
the financial intermediary or as a per transaction fee.

     Not all financial intermediaries receive additional compensation and the
amount of compensation paid varies for each financial intermediary. In certain
cases, these payments could be significant. Pioneer determines which firms to
support and the extent of the payments it is willing to make, generally
choosing firms that have a strong capability to effectively distribute shares
of the Pioneer Funds and that are willing to cooperate with Pioneer's
promotional efforts. Pioneer also may compensate financial intermediaries for
providing certain administrative services and transaction processing services.

     Pioneer may benefit from revenue sharing if the intermediary features the
Pioneer Funds in its sales system (such as by placing certain Pioneer Funds on
its preferred fund list or giving access on a preferential basis to members of
the financial intermediary's sales force or management). In addition, the
financial intermediary may agree to participate in the distributor's marketing
efforts (such as by helping to facilitate or provide financial assistance for
conferences, seminars or other programs at which Pioneer personnel may make
presentations on the funds to the intermediary's sales force). To the extent
intermediaries sell more shares of the Pioneer Funds or retain shares of the
Pioneer Funds in their clients' accounts, Pioneer receives greater management
and other fees due to the increase in the Pioneer Funds' assets. Although an
intermediary may request additional compensation from Pioneer to offset costs
incurred by the financial intermediary in servicing its clients, the
intermediary may earn a profit on these payments, if the amount of the payment
may exceed the intermediary's costs.

     The compensation that Pioneer pays to financial intermediaries is
discussed in more detail in the fund's statement of additional information.
Your intermediary may charge you additional fees or commissions other than
those disclosed in this prospectus. Intermediaries may categorize and disclose
these arrangements differently than the discussion above and in the statement
of additional information. You can ask your financial intermediary about any
payments it receives from Pioneer or the Pioneer Funds, as well as about fees
and/or commissions it charges.

     Pioneer and its affiliates may have other relationships with your
financial intermediary relating to the provision of services to the funds, such
as providing omnibus account services or effecting portfolio transactions for
the Pioneer Funds. If your intermediary provides these


                                       72


services, Pioneer or the Pioneer Funds may compensate the intermediary for
these services. In addition, your intermediary may have other relationships
with Pioneer or its affiliates that are not related to the funds.

     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
described herein or in a Pioneer Fund's prospectus. Ask your investment
professional for more information.

     If you invest in a Pioneer Fund through investment professionals or other
financial intermediaries, including wrap programs and fund supermarkets,
additional conditions may apply to your investment in a Pioneer fund, and the
investment professional or intermediary may charge you a transaction-based or
other fee for its services. These conditions and fees are in addition to those
imposed by the Pioneer Fund and its affiliates. You should ask your investment
professional or financial intermediary about its services and any applicable
fees.

     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 transfer agent for account applications, account
options forms and other account information:

PIONEER INVESTMENT MANAGEMENT SHAREHOLDER SERVICES, INC.
P.O. Box 55014

     Telephone Transaction Privileges. If your account is registered in your
name, you can buy, exchange or sell shares of the Pioneer funds 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 validating information for the account and sends
you a written confirmation. Each Pioneer 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.

     Online Transaction Privileges. If your account is registered in your name,
you may be able to buy, exchange or sell fund shares online. Your investment
firm may also be able to buy, exchange or sell your fund shares online.

     To establish online transaction privileges complete an account options
form, write to the transfer agent or complete the online authorization screen
on www.pioneerinvestments.com.

     To use online transactions, you must read and agree to the terms of an
online transaction agreement available on the Pioneer website. When you or your
investment firm requests an online transaction the transfer agent
electronically records the transaction, requires an authorizing password and
sends a written confirmation. Each Pioneer fund may implement other 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. You may not be able to use the online
transaction privilege for certain types of accounts, including most retirement
accounts.

     Share Price. If you place an order to purchase, exchange, or sell shares
with the transfer agent, your investment firm or plan administrator by the
close of regular trading on the New York Stock Exchange (currently 4:00 p.m.
Eastern time), your transaction will be completed at the share price determined
as of the close of trading on the New York Stock Exchange on that day. If your
order is placed with the transfer agent, your investment firm or plan
administrator after 4:00 p.m., or your order is not in good order, your
transaction will be completed at the share price next determined after your
order is received in good order by the fund. Your investment firm or plan
administrator is responsible for transmitting your order to the fund in a
timely manner.

     Buying Pioneer Fund Shares. You may buy shares of a Pioneer fund from any
investment firm that has a sales agreement with PFD. 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. Participants in retirement plans
generally must contact the plan's administrator to purchase shares.

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

     Minimum Investment Amounts. Your initial investment for Class A, Class B
and Class C shares must be at least $1,000, and for Class Y shares must be at
least $5,000,000. There is no minimum initial investment amount for Class R
shares. Additional investments must be at least $100 for Class A shares and
$500 for Class B and Class C shares. There is no minimum additional investment
amount


                                       73


for Class Y or Class R 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. The minimum investment amount does not apply for purposes of the
Reorganization.

     Maximum Purchase Amounts. Purchases of fund shares are limited to $49,999
for Class B shares and $999,999 for Class C shares. These limits are applied on
a per transaction basis. Class A shares, Class Y shares and Class R shares are
not subject to a maximum purchase amount.

     Exchanging Pioneer Fund Shares. You may exchange your shares in a Pioneer
Fund for shares of the same class of another Pioneer mutual fund. In connection
with the Reorganization, Pioneer Government Income Fund's Class A shareholders
will have the opportunity to exchange their shares for Class Y shares of
Pioneer Government Income Fund at net asset value without any initial or
contingent sales charge. Your exchange request must be for at least $1,000
unless the fund you are exchanging into has a different minimum. You may make
up to four exchange redemptions of $25,000 or more per account per calendar
year. In determining whether the exchange redemption limit has been reached,
Pioneer may aggregate a series of exchanges (each valued at less than $25,000)
and/or fund accounts that appear to be under common ownership or control.
Pioneer may view accounts for which one person gives instructions or accounts
that act on advice provided by a single source to be under common control.

     The exchange limitation does not apply to automatic exchange transactions
or to exchanges made by participants in employer-sponsored retirement plans
qualified under Section 401(a) of the Code. While financial intermediaries that
maintain omnibus accounts that invest in the fund are requested to apply the
exchange limitation policy to shareholders who hold shares through such
accounts, we do not impose the exchange limitation policy at the level of the
omnibus account and are not able to monitor compliance by the financial
intermediary with this policy.

     Each Pioneer 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. An exchange generally is treated as a sale and a new
purchase of shares for federal income tax purposes. Shares you acquire as part
of an exchange and shares your acquire as a result of this Reorganization 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 Pioneer Fund Shares. Your shares will be sold at net asset value
per share next calculated after the Pioneer Fund or its authorized agent
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. Each
Pioneer 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
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 or any
distributions received in cash or additional shares.

     Good order means that:

     o  You have provided adequate instructions

     o  There are no outstanding claims against your account

     o  There are no transaction limitations on your account

     o  If you have any Pioneer 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 or exchanging over $500,000 worth of
            shares

        --  Changed your account registration or address within the last 30 days

        --  Instruct the transfer agent to mail the check to an address
            different from the one on your account

        --  Want the check paid to someone other than the account owner(s)

        --  Are transferring the sale proceeds to a Pioneer mutual fund account
            with a different registration

                      amount of the purchase from your bank account of
                      record. The transfer agent will purchase fund

Pioneer Fund Shareholder Account Policies

     Signature Guarantees and Other Requirements. You are required to obtain a
signature guarantee when you are:

     o  Requesting certain types of exchanges or sales of Pioneer Fund shares

     o  Redeeming shares for which you hold a share certificate

     o  Requesting certain types of changes for your existing account

     You can obtain a signature guarantee from most broker-dealers, banks,
credit unions (if authorized under state law) and federal savings and loan
associations. You cannot obtain a signature guarantee from a notary public.

     The Pioneer Funds generally will accept only medallion signature
guarantees. A medallion signature guarantee may be obtained from a domestic
bank or trust company, broker, dealer, clearing agency, savings association, or
other financial institution that is participating in a medallion program
recognized by the Securities Transfer Association. Signature guarantees from
financial institutions that are not participating in one of these programs are
not accepted as medallion signature guarantees. The Pioneer Funds may accept
other forms of guarantee from financial intermediaries in limited
circumstances.

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

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

     The exchange limitation does not apply to automatic exchange transactions
or to exchanges made by participants in employer-sponsored retirement plans
qualified under Section 401(a) of the Code. While financial intermediaries that
maintain omnibus accounts that invest in the fund are requested to apply the
exchange limitation policy to shareholders who hold shares through such
accounts, we do not impose the exchange limitation policy at the level of the
omnibus account and are not able to monitor compliance by the financial
intermediary with this policy.

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

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

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

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

                                       77


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

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

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

     Excessive Trading. Frequent trading into and out of the fund can disrupt
portfolio management strategies, harm fund performance by forcing the fund to
hold excess cash or to liquidate certain portfolio securities prematurely and
increase expenses for all investors, including long-term investors who do not
generate these costs. An investor may use short-term trading as a strategy, for
example, if the investor believes that the valuation of the fund's portfolio
securities for purposes of calculating its net asset value does not fully
reflect the then current fair market value of those holdings. The fund
discourages, and does not take any intentional action to accommodate, excessive
and short-term trading practices, such as market timing. Although there is no
generally applied standard in the marketplace as to what level of trading
activity is excessive, we may consider trading in the fund's shares to be
excessive for a variety of reasons, such as if:

     o  You sell shares within a short period of time after the shares were
        purchased;

     o  You make two or more purchases and redemptions within a short period of
        time;

     o  You enter into a series of transactions that is indicative of a timing
        pattern or strategy; or

     o  We reasonably believe that you have engaged in such practices in
        connection with other mutual funds.

     The fund's Board of Trustees has adopted policies and procedures with
respect to frequent purchases and redemptions of fund shares by fund investors.
Pursuant to these policies and procedures, we monitor selected trades on a
daily basis in an effort to detect excessive short-term trading. If we
determine that an investor or a client of a broker has engaged in excessive
short-term trading that we believe may be harmful to the fund, we will ask the
investor or broker to cease such activity and we will refuse to process
purchase orders (including purchases by exchange) of such investor, broker or
accounts that we believe are under their control. In determining whether to
take such actions, we seek to act in a manner that is consistent with the best
interests of the fund's shareholders.

     While we use our reasonable efforts to detect excessive trading activity,
there can be no assurance that our efforts will be successful or that market
timers will not employ tactics designed to evade detection. If we are not
successful, your return from an investment in the fund may be adversely
affected. Frequently, fund shares are held through omnibus accounts maintained
by financial intermediaries such as brokers and retirement plan administrators,
where the holdings of multiple shareholders, such as all the clients of a
particular broker, are aggregated. Our ability to monitor trading practices by
investors purchasing shares through omnibus accounts is limited and dependent
upon the cooperation of the financial intermediary in observing the fund's
policies.

     In addition to monitoring trades, the policies and procedures provide
that:

     o  The fund imposes limitations on the number of exchanges out of an
        account holding the fund's Class A, Class B, Class C or Class R shares
        that may occur in any calendar year.

     o  Certain funds managed by Pioneer have adopted redemption fees that are
        incurred if you redeem shares within a short period after purchase,
        including exchanges. These redemption fees are described in the
        applicable prospectuses under "Fees and expenses."

     The fund may reject a purchase or exchange order before its acceptance or
an order prior to issuance of shares. The fund may also restrict additional
purchases or exchanges in an account. Each of these steps may be taken, for any
reason, without prior notice, including transactions that the fund believes are
requested on behalf of market timers. The fund reserves the right to reject any
purchase request by any investor or financial institution if the fund believes
that any combination of trading activity in the account or related accounts is
potentially disruptive to the fund. A prospective investor whose purchase or
exchange order is rejected will not achieve the investment results, whether
gain or loss, that would have been realized if the order were accepted and an
investment made in the fund. The fund and its shareholders do not incur any
gain or loss as a result of a rejected order. The fund may impose further
restrictions on trading activities by market timers in the future. The fund's
prospectus will be amended or supplemented to reflect any material additional
restrictions on trading activities intended to prevent excessive trading.

     Minimum Account Size. Each Pioneer Fund requires that you maintain a
minimum account value of $500. If you hold less than $500 in your account, the
fund reserves the right to notify you that it intends to sell your shares and
close your account. You will be given 60 days from the date of the notice to
make additional investments to avoid having your shares sold. This policy does
not apply to certain qualified retirement plan accounts.

     Telephone and Website Access. You may have difficulty contacting the fund
by telephone during times of market volatility or disruption in telephone
service. On New York Stock Exchange holidays or on days when the exchange
closes early, Pioneer will adjust the hours for the telephone center and for
online transaction processing accordingly. If you are unable to reach the fund
by telephone, you should communicate with the fund in writing.

     Share Certificates. The Pioneer Funds do not offer share certificates.
Shares are electronically recorded. Any existing certificated shares can only
be sold by returning your certificate to the transfer agent, along with a
letter of instruction or a stock power (a separate written authority
transferring ownership) and a signature guarantee.

     Other Policies. The fund and PFD reserve the right to:

     o  reject any purchase or exchange order for any reason, without prior
        notice

     o  charge a fee for exchanges or to modify, limit or suspend the exchange
        privilege at any time without notice. The fund will provide 60 days'
        notice of material amendments to or termination of the exchange
        privilege

     o  revise, suspend, limit or terminate the account options or services
        available to shareowners at any time, except as required by the rules of
        the SEC

     The fund reserves the right to:

     o  suspend transactions in shares when trading on the New York Stock
        Exchange is closed or restricted, when the SEC determines an emergency
        or other circumstances exist that make it impracticable for the fund to
        sell or value its portfolio securities

     o  redeem in kind by delivering to you portfolio securities owned by the
        fund rather than cash. Securities you receive this way may increase or
        decrease in value while you hold them and you may incur brokerage and
        transaction charges and tax liability when you convert the securities to
        cash

     Dividends and Capital Gains. Pioneer America Income Trust generally pays
any distributions of net short- and long-term capital gains in November, and
generally pays dividends from any net investment income on the last business
day of the month or shortly thereafter. Pioneer Government Income Fund
generally pays any distributions of net short- and long-term capital gains in
November, and generally pays dividends from any net investment income on the
last business day of the month or shortly thereafter. Pioneer Florida Tax Free
Income Fund generally pays any distributions of net short- and long-term
capital gains in November, and generally pays dividends from any net investment
income on the last business day of the month or shortly thereafter. Pioneer
AMT-Free Municipal Fund generally pays any distributions of net short- and
long-term capital gains in November, and generally pays dividends from any net
investment income on the last business day of the month or shortly thereafter.
Pioneer Balanced Fund generally pays any distributions of net short- and
long-term capital gains in November, and generally pays dividends from any net
investment income quarterly during March, June, September and December. Pioneer
Classic Balanced Fund generally pays any distributions of net short- and
long-term capital gains in November, and generally pays dividends from any net
investment income quarterly during March, June, September and December. Pioneer
Focused Equity Fund generally pays any distributions of net short- and
long-term capital gains in November, and generally pays dividends from any net
investment income in December. Pioneer Research Fund generally pays any
distributions of net short- and long-term capital gains in November, and
generally pays dividends from any net investment income in December. Each
Pioneer Fund may also pay dividends and capital gain distributions at other
times if necessary for the fund to avoid U.S. federal income or excise tax. If
you invest in the fund close to the time that the fund makes a distribution,
generally you will pay a higher price per share and you will pay taxes on the
amount of the distribution whether you reinvest the distribution or receive it
as cash.

     Taxes. For U.S. federal income tax purposes, distributions from each
fund's net long-term capital gains (if any) are considered long-term capital
gains and may be taxable to you at different maximum rates depending upon their
source and other factors. Distributions from a fund's net short-term capital
gains are taxable as ordinary income. Dividends, other than exempt-interest
dividends, are taxable either as ordinary income or, if so designated by a fund
and certain other conditions, including holding period requirements, are met by
the fund and the shareholder, as "qualified dividend income" taxable to
individual shareholders at a maximum 15% U.S. federal income tax rate.
Generally, none of the dividends of Pioneer America Income Trust, Pioneer
Government Income Fund, Pioneer Florida Tax Free Income Fund and Pioneer
AMT-Free Municipal Fund meet the requirements to be treated as qualified
dividend income. Dividends, other than exempt-interest dividends, and
distributions are taxable, whether you take payment in cash or reinvest them to
buy additional fund shares.

     When you sell or exchange fund shares you will generally recognize a
capital gain or capital loss in an amount equal to the difference between the
net amount of sale proceeds (or, in the case of an exchange, the fair market
value of the shares) that you receive and your tax basis for the shares that
you sell or exchange. In January of each year the fund will mail to you
information about your dividends, distributions and any shares you sold in the
previous calendar year.

     You must provide your social security number or other taxpayer
identification number to the fund along with the certifications required by the
Internal Revenue Service when you open an account. If you do not or if it is
otherwise legally required to do so, the fund will withhold 28% "backup
withholding" tax from your dividends and distributions, sale proceeds and any
other payments to you.

     You should ask your tax adviser about any federal, state, local and
foreign 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 qualified dividend income and
other U.S. federal income tax considerations that may affect the fund and its
shareowners.

                      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 or PIMSS, or by broker-dealer
firms. Pioneer and its affiliates, together with a third party solicitation
firm, have agreed to provide proxy solicitation services to your fund at a cost
of approximately $267,000. Pioneer has agreed to pay 50% of the costs of
preparing and printing the Proxy Statement/Prospectus and the solicitation
costs incurred in connection with the Reorganizations. With respect to each
Reorganization, the Pioneer Funds will each pay an equal portion of the
remaining 50% of the costs incurred in connection with the such Reorganization.

Revoking Proxies

     Each shareholder of your fund 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 your fund's transfer
        agent, Pioneer Investment Management Shareholder Services, Inc., 60
        State Street, Boston, Massachusetts 02109, or

     o  By returning a duly executed proxy with a later date before the time of
        the 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.

Other Business

     Your fund's Board of Trustees knows of no business to be presented for
consideration at the meeting other than Proposals 1(a) -- 1(d). 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

     If, by the time scheduled for the meeting, a quorum of shareholders of
fund is not present or if a quorum is present but sufficient votes "for" the
proposal have not been received, the persons named as proxies may propose an
adjournment of the meeting to another date and time, and the meeting may be
held as adjourned within a reasonable time after the date set for the original
meeting without further notice. Any such adjournment will require the
affirmative vote of a majority of the votes cast in person or by proxy at the
session of the meeting to be adjourned. The persons named as proxies will vote
all proxies in favor of the adjournment that voted in favor of the proposal or
that abstained. They will vote against such adjournment those proxies required
to be voted against the proposal. Broker non-votes will be disregarded in the
vote for adjournment. If the adjournment requires setting a new record date or
the adjournment is for more than 120 days of the original meeting (in which
case the Board of Trustees of your fund will set a new record date), your fund
will give notice of the adjourned meeting to its shareholders.

Telephone and Internet Voting

     In addition to soliciting proxies by mail, by fax or in person, your fund
may also arrange to have votes recorded by telephone, the Internet or other
electronic means. The voting procedures used in connection with such voting
methods are designed to authenticate shareholders' identities, to allow
shareholders to authorize the voting of their shares in accordance with their
instructions and to confirm that their instructions have been properly
recorded. If these procedures were subject to a successful legal challenge,
such votes would not be counted at the shareholder meeting. The funds are
unaware of any such challenge at this time. In the case of telephone voting,
shareholders would be called at the phone number PIMSS has in its records for
their accounts and would be asked for their Social Security number or other
identifying information. The shareholders would then be given an opportunity to
authorize proxies to vote their shares at the meeting in accordance with their
instructions. In the case of automated telephone and Internet voting,
shareholders would be required to provide their identifying information and
will receive a confirmation of their instructions.

Shareholders' Proposals

     Your fund is not required, and does not intend, to hold meetings of
shareholders each year. Instead, meetings will be held only when and if
required. Any shareholders desiring to present a proposal for consideration at
the next meeting for shareholders must submit the proposal in writing, so that
it is received by your fund at 60 State Street, Boston, Massachusetts 02109
within a reasonable time before the meeting.

name other than the registered holder of the Acquired 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 Any reporting responsibility of the Acquired Trust with respect to the
Acquired Fund for taxable periods ending on or before the Closing Date,
including, but not limited to, the responsibility for filing of regulatory
reports, Tax Returns (as defined in Paragraph 4.1), or other documents with the
Commission, any state securities commissions, and any federal, state or local

     3.5 The Acquired Fund shall deliver at the Closing a list of the names,

service providers. The Acquiring Fund shall issue and deliver to the Acquired
Fund a confirmation evidencing the Acquiring Fund Shares to be credited on the

hereof and on the Closing Date as though made on and as of the Closing Date, as
follows:

     (a) The Acquired Fund is a series of the Acquired Trust. The Acquired
    Trust is a [statutory] [business] trust validly existing and in good
    standing under the laws of the [State of Delaware] [Commonwealth of
    Massachusetts] and has the power to own all of its properties and assets
    and, subject to approval by the Acquired Fund's shareholders, 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 subject it to any material liability or
    disability. Each of the Acquired Trust and 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 conducted;


     (b) The Acquired Trust a registered investment company classified as a
    management company of the open-end type, and its registration with the
    Commission as an investment company under the Investment Company Act is in
    full force and effect;

     (c) The Acquired Trust is not in violation of, and the execution and
    delivery of this Agreement and the performance of its obligations under
    this Agreement in respect of the Acquired Fund will not result in a
    violation of, any provision of the Acquired Trust's Declaration or By-Laws
    or any material agreement, indenture, instrument, contract, lease or other
    undertaking with respect to the Acquired Trust to which the Acquired Fund
    is a party or by which the Acquired Fund or any of its assets are bound;

     (d) No litigation or administrative proceeding or investigation of or
    before any court or governmental body is currently pending or to its
    knowledge threatened against the Acquired Fund or any of the Acquired
    Fund's properties or assets. Neither the Acquired


                                      A-3


  Trust nor the Acquired Fund knows of no facts that might form the basis for
  the institution of such proceedings. 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 adversely affects the Acquired Fund's
  business or its ability to consummate the transactions contemplated herein
  or would be binding upon the Acquiring Fund as the successor to the Acquired
  Fund;

     (e) The Acquired Fund has no material contracts or other commitments
    (other than this Agreement or agreements for the purchase and sale of
    securities entered into in the ordinary course of business and consistent
    with its obligations under this Agreement) which will not be terminated at
    or prior to the Closing Date and no such termination will result in
    liability to the Acquired Fund (or the Acquiring Fund);

     (f) The statement of assets and liabilities of the Acquired Fund, and the
    related statements of operations and changes in net assets, as of and for
    the fiscal year ended [December 31, 2005] [July 31, 2005], have been
    audited by an independent registered public accounting firm retained by
    the Acquired Fund, and are in accordance with generally accepted
    accounting principles ("GAAP") consistently applied and fairly reflect, in
    all material respects, the financial condition of the Acquired Fund as of
    such date and the results of its operations for the period then ended, and
    all known liabilities, whether actual or contingent, of the Acquired Fund
    as of the date thereof are disclosed therein. The Statement of Assets and
    Liabilities will be in accordance with GAAP consistently applied and will
    fairly reflect, in all material respects, the financial condition of the
    Acquired Fund as of such date and the results of its operations for the
    period then ended. Except for the Assumed Liabilities, the Acquired Fund
    will not have any known or contingent liabilities on the Closing Date. No
    significant deficiency, material weakness, fraud, significant change or
    other factor that could significantly affect the internal controls of the
    Acquired Fund has been disclosed or is required to be disclosed in the
    Acquired Fund's reports on Form N-CSR to enable the chief executive
    officer and chief financial officer or other officers of the Acquired Fund
    to make the certifications required by the Sarbanes-Oxley Act, and no
    deficiency, weakness, fraud, change, event or other factor exists that
    will be required to be disclosed in the Acquiring Fund's Form N-CSR after
    the Closing Date;

     (g) Since the most recent fiscal year end, except as specifically
    disclosed in the Acquired Fund's prospectus, its statement of additional
    information as in effect on the date of this Agreement, [or its
    semi-annual report for the six-month period ended January 31, 2006,] there
    has not been any material adverse change in the Acquired Fund's financial
    condition, assets, liabilities, business or prospects, or any incurrence
    by the Acquired Fund of indebtedness, except for normal contractual
    obligations incurred in the ordinary course of business or in connection
    with the settlement of purchases and sales of portfolio securities. For
    the purposes of this subparagraph (g) (but not for any other purpose of
    this Agreement), a decline in NAV per Acquired Fund Share arising out of
    its normal investment operations or a decline in market values of
    securities in the Acquired Fund's portfolio or a decline in net assets of
    the Acquired Fund as a result of redemptions shall not constitute a
    material adverse change;

      (h) (A) For each taxable year of its operation since its inception, the
        Acquired Fund has satisfied, and for the current taxable year it will
        satisfy, the requirements of Subchapter M of the Code for qualification
        and treatment as a regulated investment company. The Acquired Fund will
        qualify as such as of the Closing Date and will satisfy the
        diversification requirements of Section 851(b)(3) of the Code without
        regard to the last sentence of Section 851(d) of the Code. The Acquired
        Fund has not taken any action, caused any action to be taken or caused
        any action to fail to be taken which action or failure could cause the
        Acquired Fund to fail to qualify as a regulated investment company
        under the Code;

        (B) Within the times and in the manner prescribed by law, the Acquired
      Fund has properly filed on a timely basis all Tax Returns (as defined
      below) that it was required to file, and all such Tax Returns were
      complete and accurate in all material respects. The Acquired Fund has not
      been informed by any jurisdiction that the jurisdiction believes that the
      Acquired Fund was required to file any Tax Return that was not filed; and
      the Acquired Fund does not know of any basis upon which a jurisdiction
      could assert such a position;

        (C) The Acquired Fund has timely paid, in the manner prescribed by law,
      all Taxes (as defined below), which were due and payable or which were
      claimed to be due;

        (D) All Tax Returns filed by the Acquired Fund constitute complete and
      accurate reports of the respective Tax liabilities and all attributes of
      the Acquired Fund or, in the case of information returns and payee
      statements, the amounts required to be reported, and accurately set forth
      all items required to be included or reflected in such returns;

        (E) The Acquired Fund has not waived or extended any applicable statute
      of limitations relating to the assessment or collection of Taxes;

        (F) The Acquired Fund has not been notified that any examinations of
      the Tax Returns of the Acquired Fund are currently in progress or
      threatened, and no deficiencies have been asserted or assessed against
      the Acquired Fund as a result of any audit


                                      A-4


      by the Internal Revenue Service or any state, local or foreign taxing
      authority, and, to its knowledge, no such deficiency has been proposed or
      threatened;

        (G) The Acquired Fund has no actual or potential liability for any Tax
      obligation of any taxpayer other than itself. The Acquired Fund is not
      and has never been a member of a group of corporations with which it has
      filed (or been required to file) consolidated, combined or unitary Tax
      Returns. The Acquired Fund is not a party to any Tax allocation, sharing,
      or indemnification agreement;

        (H) The unpaid Taxes of the Acquired Fund for tax periods through the
      Closing Date do not exceed the accruals and reserves for Taxes (excluding
      accruals and reserves for deferred Taxes established to reflect timing
      differences between book and Tax income) set forth on the Statement of
      Assets and Liabilities, as defined in paragraph 5.7, rather than in any
      notes thereto (the "Tax Reserves"). All Taxes that the Acquired Fund is
      or was required by law to withhold or collect have been duly withheld or
      collected and, to the extent required, have been timely paid to the
      proper governmental agency;

        (I) The Acquired Fund has delivered to the Acquiring Fund or made
      available to the Acquiring Fund complete and accurate copies of all Tax
      Returns of the Acquired Fund, together with all related examination
      reports and statements of deficiency for all periods not closed under the
      applicable statutes of limitations and complete and correct copies of all
      private letter rulings, revenue agent reports, information document
      requests, notices of proposed deficiencies, deficiency notices, protests,
      petitions, closing agreements, settlement agreements, pending ruling
      requests and any similar documents submitted by, received by or agreed to
      by or on behalf of the Acquired Fund. The Acquired Fund has disclosed on
      its federal income Tax Returns all positions taken therein that could
      give rise to a substantial understatement of federal income Tax within
      the meaning of Section 6662 of the Code;

        (J) The Acquired Fund has not undergone, has not agreed to undergo, and
      is not required to undergo (nor will it be required as a result of the
      transactions contemplated in this Agreement to undergo) a change in its
      method of accounting resulting in an adjustment to its taxable income
      pursuant to Section 481 of the Code. The Acquired Fund will not be
      required to include any item of income in, or exclude any item of
      deduction from, taxable income for any taxable period (or portion
      thereof) ending after the Closing Date as a result of any (i) change in
      method of accounting for a taxable period ending on or prior to the
      Closing Date under Section 481(c) of the Code (or any corresponding or
      similar provision of state, local or foreign income Tax law); (ii)
      "closing agreement" as described in Section 7121 of the Code (or any
      corresponding or similar provision of state, local or foreign income Tax
      law) executed on or prior to the Closing Date; (iii) installment sale or
      open transaction disposition made on or prior to the Closing Date; or
      (iv) prepaid amount received on or prior to the Closing Date;

        (K) The Acquired Fund will not have taken or agreed to take any action,
      and will not be aware of any agreement, plan or other circumstance, that
      is inconsistent with the representations set forth in the Acquired Fund
      Representation Certificate to be delivered pursuant to paragraph 7.4;

        (L) There are (and as of immediately following the Closing there will
      be) no liens on the assets of the Acquired Fund relating to or
      attributable to Taxes, except for Taxes not yet due and payable;

        (M) The Tax bases of the assets of the Acquired Fund are accurately
      reflected on the Acquired Fund's Tax books and records; and

        (N) For purposes of this Agreement, "Taxes" or "Tax" shall mean all
      taxes, charges, fees, levies or other similar assessments or liabilities,
      including without limitation income, gross receipts, ad valorem, premium,
      value-added, excise, real property, personal property, sales, use,
      transfer, withholding, employment, unemployment, insurance, social
      security, business license, business organization, environmental, workers
      compensation, payroll, profits, license, lease, service, service use,
      severance, stamp, occupation, windfall profits, customs, duties,
      franchise and other taxes imposed by the United States of America or any
      state, local or foreign government, or any agency thereof, or other
      political subdivision of the United States or any such government, and
      any interest, fines, penalties, assessments or additions to tax resulting
      from, attributable to or incurred in connection with any tax or any
      contest or dispute thereof; and "Tax Returns" shall mean all reports,
      returns, declarations, statements or other information required to be
      supplied to a governmental or regulatory authority or agency, or to any
      other person, in connection with Taxes and any associated schedules or
      work papers produced in connection with such items;

     (i) All issued and outstanding Acquired Fund Shares are, and at the
    Closing Date will be, legally issued and outstanding, fully paid and
    nonassessable by the Acquired Fund. All of the issued and outstanding
    Acquired Fund Shares will, at the time of Closing, be held of record by
    the persons and in the amounts set forth in the Shareholder List submitted
    to the Acquiring Fund pursuant to Paragraph 3.5 hereof. The Acquired Fund
    does not have outstanding any options, warrants or other rights to
    subscribe for or purchase any Acquired Fund Shares, nor is there
    outstanding any security convertible into any Acquired Fund Shares;


                                      A-5


     (j) At the Closing Date, the Acquired Fund will have good and marketable
    title to the Acquired Assets, and full right, power and authority to sell,
    assign, transfer and deliver the Acquired Assets to the Acquiring Fund,

    action on the part of the Acquired Fund's Board of Trustees, and, subject
    to the approval of the Acquired Fund's shareholders, assuming due
    authorization, execution and delivery by the Acquiring Fund, this
    Agreement will constitute a valid and binding obligation of the Acquired
    Fund, enforceable in accordance with its terms, subject as to enforcement,
    to bankruptcy, insolvency, reorganization, moratorium and other laws
    relating to or affecting creditors' rights and to general equity
    principles;

     (l) The information to be furnished by the Acquired Fund to the Acquiring
    Fund for use in applications for orders, registration statements, proxy

    complete and shall comply in all material respects with federal securities
    and other laws and regulations applicable thereto;

    the fiscal year ended [December 31, 2005] [July 31, 2005] have been
    audited by Ernst & Young LLP, independent registered public accounting

    its normal investment operations or a decline in market values of
    securities in the Acquiring Fund's portfolio or a decline in net assets of

      Fund does not know of any basis upon which a jurisdiction could assert

      law, all Taxes that were due and payable or that were claimed to be due;

      pursuant to paragraph 6.3;

        (L) There are (and as of immediately following the Closing there will

    Acquiring Fund Shares to be issued and delivered to the Acquired Fund for
    the account of the Acquired Fund Shareholders pursuant to the terms of
    this Agreement will have been duly authorized on the Closing Date and,
    when so issued and delivered, will be legally issued and outstanding,

    and perform its obligations under this Agreement. The execution, delivery
    and performance of this Agreement have been duly authorized by all
    necessary action on the part of the Acquiring Trust's Board of Trustees,
    and, assuming due authorization, execution and delivery by the Acquired
    Fund, this Agreement will constitute a valid and binding obligation of the

    enforcement, to bankruptcy, insolvency, reorganization, moratorium and
    other laws relating to or affecting creditors' rights and to general
    equity principles;

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 4.5% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

The performance of the Class A shares of the fund includes the performance of
AmSouth Government Income Fund's Class A shares prior to the reorganization,
which has been restated to reflect differences in any applicable sales charges
(but not differences in expenses). Pioneer Government Income Fund was created
through the reorganization of AmSouth Government Income Fund on September 23,
2005. If the performance had been adjusted to reflect all differences in
expenses, the performance of the fund would be lower.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

to withdrawals was shortened to 5 years. The maximum CDSC for Class B shares
continues to be 4%. For more complete information, please see the prospectus

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not
reflect the 1% front-end sales charge in effect prior to February 1, 2004. If
you paid a 1% sales charge, your returns would be lower than those shown above.
"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

The performance of the Class C shares is based upon the performance of the
fund's Class B shares as adjusted to reflect sales charges applicable to Class
C shares (but not other differences in expenses). Pioneer Government Income
Fund was created through the reorganization of AmSouth Government Income Fund
on September 23, 2005. If the performance had been adjusted to reflect all
differences in expenses, the performance of the fund would be lower.

Performance results reflect any applicable expense waivers in effect during the

PORTFOLIO MANAGEMENT DISCUSSION
PIONEER GOVERNMENT INCOME FUND 1/31/06

Continued economic growth and rising short-term interest rates during the last
six months created the backdrop for the positive return earned by shareholders
in Pioneer Government Income Fund. In the following interview, Richard
Schlanger, the Fund's Portfolio Manager and a member of the Pioneer
fixed-income team, discusses the factors that affected the fixed-income market
and the Fund over the past half year.

Q. How did the Fund perform during the period?

A: For the six-month period ended January 31, 2006, Class A shares of Pioneer
   Government Income Fund produced a total return of 0.67% at net asset value.
   The Fund underperformed its benchmark, the Lehman Brothers Government Bond
   Index, which returned 0.77% for the same period. It also fell short of the
   1.28% return of the Lehman Brothers Fixed Rate Mortgage-Backed Securities
   Index and the average 0.86% return generated by the funds in the U.S.
   Mortgage Funds Category of Lipper, an independent monitor of mutual fund
   performance. At the end of the period, the 30-day SEC yield for Class A
   shares was 3.58%. The Fund held 106 issues with an average quality of AAA.

   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q. What was the investment environment like during the period?

A: In an environment of relatively strong economic growth, the Federal Reserve
   raised the federal funds rate five times from 3.25% to 4.50% during the
   period. The Fed's actions resulted in a flattening of the yield curve, with
   short-term yields and longer-term yields at approximately the same level. For
   a short period, the yield curve inverted slightly, with longer-term yields
   falling below short-term yields.

   While long-term yields on U.S. Treasury bonds were relatively low, they were
   among the highest among the developed countries, making them attractive to
   overseas investors. As a result, U.S. Government bonds benefited from an
   influx of money from foreign, as well as domestic, investors. The
   performance of government bonds was also enhanced by investors seeking
   quality. At a time when long-term yields declined and the bonds of corporate
   issuers, like General Motors and Ford, were downgraded by credit rating
   agencies, domestic investors saw little advantage to take on greater risk.
   As a result, they moved to purchasing government securities with relative
   safety.

Q. What strategies did you use in managing the Fund?

A: We continued to seek a high level of income without unduly risking capital.
   In making our investment decisions, we considered a variety of factors that
   influence economic activity and interest rates. These included the rates of
   economic growth and inflation, Federal Reserve monetary policy and the
   relative value of the U.S. dollar against world currencies. To take advantage
   of the flattening yield curve, we extended the portfolio's duration.

   At the beginning of the period, the portfolio had a relatively small
   Treasury bond position and a large allocation to mortgage-backed securities.
   Among mortgages, securities issued by the Federal National Mortgage
   Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation
   (Freddie Mac) accounted for a far greater percentage of assets than those
   issued by the Government National Mortgage Association (Ginnie Mae). Because
   we believed mortgages had become too high priced and subject to prepayment,
   we lowered the Fund's mortgage holdings, while increasing the percentage of
   Treasury bonds. We established a position in Treasury Inflation Protected
   Securities (TIPS) on the belief that inflation might pick up. TIPS are
   securities whose principal is tied to the consumer price index, which is a
   monthly indicator that measures the price inflation of a representative
   basket of goods and services. When inflation accelerates, the principal on
   TIPS increases in value. The interest-rate payment on TIPS is calculated on
   the inflated principal.

Q. What contributed to performance?

A: The TIPS in the portfolio were the biggest contributor to performance. The
   portfolio's longer duration also contributed to results. Conventional
   mortgages issued by the Federal National Mortgage Association (Fannie Mae)
   and the Federal Home Loan Mortgage Corporation (Freddie Mac) underperformed
   those issued by the Government National Mortgage Association (Ginnie Mae).
   Both Fannie Mae and Freddie Mac are well represented in the top 25 holdings
   that constitute over 60% of the portfolio; Fannie Mae with


                                      B-5


   33.5% of that total and Freddie Mac with 26.7%. They also have been in the
   headlines for more than a year because of accounting irregularities and
   concerns that these agencies were undercapitalized. Both agencies sold
   portions of their mortgage investment portfolios in order to raise funds to
   meet the higher capitalization levels required by the Office of Federal
   Housing Enterprise Oversight (OFHEO). The OFHEO has stated that both
   agencies are now adequately capitalized.

Q. What is your financial outlook?

A: We are generally positive in our outlook. We think the yield curve will
   temporarily invert, with short-term yields rising above long-term yields.
   However, we believe that the Fed may be near the end of its rate-raising
   cycle. We expect to see some heightened market volatility in the short term,
   as investors become familiar with the policies and philosophy of Benjamin
   Bernanke, the new Federal Reserve chairman. With the re-issuance of the
   30-year Treasury bond, there is likely to be a greater supply of Treasury
   bonds in the next several months; however, this increase in supply is
   unlikely to affect bond prices significantly, as foreign and domestic demand
   for U.S. Treasury bonds continues to be strong. As in the past, we will
   carefully monitor the factors that influence the economy, inflation and
   monetary policy, and make adjustments to the portfolio that we believe have
   potential to increase income and preserve principal.

   When interest rates rise, the prices of fixed income securities in the Fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the Fund will generally rise. Prepayment risk is
   the chance that mortgage-backed bonds will be paid off early if falling
   interest rates prompt homeowners to refinance their mortgages. Forced to
   reinvest the unanticipated proceeds at lower interest rates, the Fund would
   experience a decline in income and lose the opportunity for additional price
   appreciation associated with falling interest rates. Investing in the
   securities of U.S. issuers with substantial foreign activities involves many
   of the same risks as investing in the securities of foreign issuers. The
   portfolio may invest in mortgage-backed securities, which during times of
   fluctuating interest rates may increase or decrease more than other fixed
   income securities. Mortgage-Backed securities are also subject to
   pre-payments.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These opinions should not be relied upon for any other purposes. Past
   performance is no guarantee of future results, and there is no guarantee that
   market forecasts discussed will be realized.

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer America Income Trust 12/31/05

In a year marked by hurricanes, high energy prices, concerns about accelerating
inflation and rising short-term interest rates, shareholders in Pioneer America
Income Trust earned a positive return on their investment. In the interview
below, Richard Schlanger, the Trust's day-to-day Portfolio Manager, discusses
the factors that affected the fixed income market and the Trust over the past
12 months.

Q. How did the Trust perform during the period?

A: For the 12-month period ended December 31, 2005, Class A shares of Pioneer
   America Income Trust produced a total return of 1.84% at net asset value. The
   Trust underperformed its benchmark, the Lehman Brothers Government Bond
   Index, which returned 2.65% for the same period. It also underperformed the
   average 2.05% return generated by the General U.S. Government Funds Category
   of Lipper, Inc., an independent monitor of mutual fund performance. At the
   end of the period, the 30-day SEC yield for Class A shares was 3.17%. The
   Trust had 260 issues and the average quality of the portfolio was AAA.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, maybe worth more or less than their
   original cost.

Q. What was the investment environment like during the period?

A: Economic growth was relatively strong, and productivity remained high. In
   this environment, the Federal Reserve continued to reverse its accommodative
   monetary policy and raised interest rates eight times during the year, each
   time by a quarter point. At the end of 2005, the federal funds target rate
   was 4.25%, up from 2.25% in January 2005. (The federal funds rate is the rate
   banks charge for overnight loans. Since June 2004, the Fed has hiked interest
   rates 13 times, taking the federal funds rate from a 40-year low of 1% to the
   current 4.25%.) The net effect of the Fed's actions was a flattening of the
   yield curve, where short-term yields and longer-term yields were
   approximately the same. On December 30, 2005, the yield curve inverted
   slightly, with longer-term yields falling below short-term yields. (The yield
   curve shows the relationship between bond yields and maturity lengths.)

   During the year, government bonds benefited from an influx of money from both
   foreign and domestic investors. While long-term yields on U.S. Treasuries
   were relatively low, they were among the highest of the developed countries
   and attractive to overseas investors. The performance of government bonds was
   also enhanced by a flight to quality. At a time when long-term yields
   declined and the debt of General Motors and Ford was downgraded by credit
   rating agencies, domestic investors saw little advantage to taking on risk.
   As a result, they moved into the relative safety of government securities.

Q. What strategies did you use in managing the Trust?

A: As interest rates rose, we extended duration, or sensitivity to interest-rate
   changes, by reducing exposure to mortgage securities and adding to positions
   in Treasury issues and Treasury Inflation Protected Securities (TIPS). TIPS
   are securities whose principal is tied to the consumer price index, a monthly
   indicator that measures the price inflation of a representative basket of
   goods and services. When inflation accelerates, the principal on TIPS
   increases in value. The interest-rate payment on TIPS is calculated on the
   inflated principal. While inflation was not a problem in 2005, we are
   concerned about the potential for it to pick up. Oil prices are over $60 a
   barrel, the price of gold is at a 25-year high and the unemployment rate fell
   below 5%. These factors and others could lead to an upturn in inflation. At
   the end of the period, 59% of the portfolio was in mortgage pass-through
   securities issued by the Government National Mortgage Association, 40% was in
   Treasury issues and TIPS, and 1% was in cash.

Q. What detracted from performance?

A: Our positioning on the yield curve held back return. Throughout the 12
   months, we maintained a bulleted strategy, which means we invested in bonds
   across the maturity spectrum, with the biggest concentration in the
   intermediate-term range of two-years to ten-years. While our short-term and
   long-term bonds did well, intermediate-term bonds detracted from performance.
   In hindsight, it would have been more advantageous to have had a barbelled
   configuration, overweighting the short and long ends of the yield curve and
   holding relatively few intermediate-term bonds.


                                      B-12


Q. What contributed to performance?

A: During the second half of 2005, yields on 10-year Treasuries traded in a
   relatively narrow range of roughly 3.90% to a high of roughly 4.68%. As
   10-year Treasuries declined in price and rose in yield, we extended duration.
   This aided results because 10-year Treasuries closed the year at 4.40%, down
   from their highs. A longer duration usually benefits a portfolio when yields
   decline. The performance of TIPS also helped boost the Trust's return.

Q. What is your outlook?

A: In general we are positive when looking ahead. While we believe the inverted
   yield curve may be indicating some moderating in economic growth, we do not
   think it is signaling recession. When the Fed began raising interest rates,
   the federal funds rate was extremely low at 1%. We think that the current
   4.25% level is not restrictive, especially with an inflation rate of roughly
   2.0% to 2.5%. While we think the consumer may cut back on spending, it is
   likely that business will pick up the slack. An increase in capital spending
   on the part of corporations may be enough to keep the economy growing at a
   respectable rate. The Fed may be in the late stages of its rate-raising
   cycle. Should the Fed ease rates somewhat, we believe intermediate-term
   securities will outperform longer-term securities. We are well-positioned
   should this occur. As we move into 2006, we believe the Trust should continue
   to provide income diversification for investors who want to avoid the risk
   associated with the more volatile areas of the fixed-income market and with
   equities.

   When interest rates rise, the prices of fixed income securities in the fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the fund will generally rise. Prepayment risk is
   the chance that mortgage-backed bonds will be paid off early if falling
   interest rates prompt homeowners to refinance their mortgages. Forced to
   reinvest the unanticipated proceeds at lower interest rates, the fund would
   experience a decline in income and lose the opportunity for additional price
   appreciation associated with falling interest rates. The portfolio may invest
   in mortgage-backed securities, which during times of fluctuating interest
   rates may increase or decrease more than other fixed-income securities.
   Mortgage-Backed securities are also subject to pre-payments. Government
   guarantees apply to the underlying securities only and not to the prices and
   yields of the portfolio. At times, the fund's investments may represent
   industries or industry sectors that are interrelated or have common risks,
   making it more susceptible to any economic, political, or regulatory
   developments or other risks affecting those industries and sectors.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Trust's historical or future
   performance are statements of the opinion of Trust management as of the date
   of this report. These opinions should not be relied upon for any other
   purposes. Past performance is no guarantee of future results, and there is no
   guarantee that market forecasts discussed will be realized.

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer Classic Balanced Fund 1/31/06

With a sustained economic recovery and steady corporate profit growth as a
backdrop, domestic equities performed relatively well during the six months
ended January 31, 2006. However, returns generally were more modest in the
fixed-income markets as the Federal Reserve Board continued to raise short-term
rates and the yield differences between long- and short-term securities
narrowed. The yield advantages of corporate bonds over government securities
also grew tighter, making investments in corporate bonds less attractive to
investors. In the following interview, Walter Hunnewell, Jr., who is one of
Pioneer Classic Balanced Fund's co-managers, and Richard Schlanger, who is a
member of Pioneer's Fixed Income team, discuss the markets and the factors that
affected performance during the six months.

Q. How did the Fund perform during the six months ended January 31, 2006?

A: Pioneer Classic Balanced Fund (Class A shares) returned 4.37% during the
   six-month period, at net asset value. During the same period, the average
   return of the 698 funds in Lipper's balanced Fund category was 4.47%. In
   comparison, the Standard and Poor's 500 Index and the Lehman Brothers
   Government/Credit Bond Index returned 4.67% and 0.58%, respectively, over the
   same period.

   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q. What strategies do you use in managing the Fund?

A: Almost two months into the period, on September 23, 2005, the former AmSouth
   Balanced Fund was reorganized as the Pioneer Classic Balanced Fund, and
   Pioneer Investment Management assumed portfolio management responsibilities.
   Since then, the Fund has been managed in accord with our equity and
   fixed-income disciplines, emphasizing fundamental research and drawing on the
   global resources of the Pioneer organization.

   As a balanced fund, the Fund is managed with the goal of seeking both capital
   growth and current income through a diversified portfolio of both equity and
   fixed-income securities. The Fund has a normal allocation of 60% equities and
   40% fixed income, but the allocation can vary depending upon Pioneer's
   assessment of relative opportunities in the markets. Since Pioneer assumed
   management responsibilities, the equity portfolio has increased from about
   60% of Fund assets to about 65% of assets. That was the result of both a
   deliberate policy to increase the Fund's emphasis on stocks and the
   appreciation of the value of equity assets in the portfolio.

Q: What were the principal factors that affected the performance of the Fund's
   bond portfolio for the period?

A: We believed that corporate bonds were becoming less attractive relative to
   mortgages and governments as their yield advantages narrowed. As a
   consequence, we reduced our corporate positions. We also de-emphasized bonds
   in the finance sector, whose earnings we believed were vulnerable as the
   Federal Reserve continued to raise short-term interest rates. We sold, for
   example, bonds issued by Prudential Funding and by Devon Financing. In
   addition, we sold DaimlerChrysler holdings because of our concerns
   surrounding the auto sector. At the same time, we added to our mortgage
   holdings and invested in long-term Treasuries because of the attractive
   income that they offered relative to other types of fixed-income securities.
   While we maintained a high quality portfolio, we looked for selective
   opportunities in corporate bonds where we had confidence in the underlying
   credit fundamentals of the companies behind them.

   The average credit quality of the portfolio's holdings was AA on January 31,
   2006. About one-third of the portfolio's assets was invested in Treasuries
   and another one-third was invested in mortgages. Government agencies
   accounted for about 10% of fixed income assets, while corporate industrial
   bonds accounted for 21%. Bank and finance bonds were reduced to about 12% of
   fixed income assets. We kept average maturity and duration - both of which
   measure sensitivity to changes in interest rates - consistent with that of
   the benchmark Lehman Brothers Government/Credit Bond Index.

   The increasing emphasis on mortgage-backed securities helped performance, as
   did the lack of exposure to some of the more notable poor-performing
   corporate bonds, including securities issued by General Motors and Ford, the
   credit ratings of which have fallen from investment-grade to below
   investment-grade.


                                      B-18


Q: What were the principal factors that affected the performance of the Fund's
   equity portfolio during the six months?

A: We shifted the portfolio's focus from a growth-oriented style to more of a
   value-oriented style, with an emphasis on reasonably priced large- and
   mid-cap stocks. We also looked to increase the dividend income from our stock
   holdings. Reflecting this shift, by January 31, 2006, the average price - as
   reflected by price/earnings ratios - of our holdings was lower than that of
   the benchmark Standard & Poor's 500 Index, but the average dividend yield was
   higher than the S&P 500's.

   In repositioning the equity portfolio, we sold our positions in many
   higher-priced growth stocks, including those of technology companies Cisco
   Systems and Qualcomm, biotechnology leader Amgen, and eBay, the Internet
   auctioneer. We established large positions in less expensively priced,
   higher-yielding companies, including Bristol-Myers and Merck, two
   pharmaceutical companies that our research indicated offered potential
   interesting opportunities after being out of favor in the market. Another new
   holding was Washington Mutual, which was trading at a low price and offered a
   relatively high yield. In addition, we invested in some companies, such as
   Federated Department Stores, not because we were attracted by their dividend
   yield, but because we believed they offered superior capital appreciation
   potential as the result of their unrecognized earnings power. We also
   established a relatively small position in several real estate investment
   trusts (REITs), which had been absent from the portfolio. However, we limited
   the Fund's exposure because of our concern about the vulnerability of REITs
   to increases in interest rates. One of our larger REIT positions was
   Brandywine Realty.

Q: What were some of the individual equity investments that particularly
   influenced results?

A: We overweighted the energy sector, which helped performance substantially as
   energy stocks rallied and the prices of commodities increased. Among the
   better performers were oil services companies such as Global Santa Fe and
   Schlumberger, as well as Marathon Oil, an integrated oil company. Deere, the
   farm equipment company, was our largest individual holding by the end of the
   six months and made a substantial contribution to performance. We increased
   our weighting in Deere because it was selling at what we thought was a very
   low price. In our opinion the dividend yield was not high, but we believed it
   offered superior price appreciation potential because we think the overall
   stock market is underestimating how long demand for farm equipment will be
   sustained. Merck, which we added to the portfolio, also performed well as its
   stock value recovered from a depressed level. One of the disappointing
   performers was Dow Chemical, whose stock price fell because investors had
   questions about pricing for ethylene products, a significant part of Dow's
   business. However, we believed that ethylene inventories are generally low
   and Dow should have an opportunity to sustain good pricing for its products.

   As a result, we continue to favor the company.

Q. What is your investment outlook?

A: We think that the economy will continue to expand and corporate profits
   should continue to improve, but the rates of economic growth and corporate
   earnings growth may begin to slow during the current year. As we enter 2006,
   we believe the stock market is reasonably valued. We also think the emphasis
   on higher dividend-paying stocks gives the Fund the potential to do well in
   the current environment. We have found interesting opportunities among
   higher-dividend pharmaceutical companies and telecommunication services
   companies and in companies that have demonstrated abilities to produce cash
   flow to support and increase their dividend payouts to shareholders.

   We believe the Federal Reserve is likely to continue to raise short-term
   interest rates, at least in the near term. In managing the fixed-income
   portfolio, we will look for signals about any shifts in policy emphasis under
   new Federal Reserve Chairman Ben Bernanke, although we think the Fed will
   remain determined to keep inflationary pressures under control. If
   longer-term interest rates were to increase significantly, bonds could
   provide an interesting opportunity for investment. Overall, we believe demand
   for U.S. securities by foreign investors should help provide continued
   support for bond prices in the United States.

   When interest rates rise, the prices of fixed income securities in the Fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the Fund will generally rise. Investments in the
   Fund are subject to possible loss due to the financial failure of underlying
   securities and their inability to meet their debt obligations. Prepayment
   risk is the chance that mortgage-backed bonds will be paid off early if
   falling interest rates prompt homeowners to refinance their mortgages. Forced
   to reinvest the unanticipated proceeds at lower interest rates, the Fund
   would experience a decline in income and lose the opportunity for additional
   price appreciation associated with falling interest rates. The portfolio
   invests in REIT securities, the value of which can fall for a variety of
   reasons, such as declines in rental income, fluctuating interest rates, poor
   property management, environmental liabilities, uninsured damage, increased
   competition, or changes in real estate tax laws. Investing in foreign and/or
   emerging markets securities involves risks relating to interest rates,
   currency exchange rates, economic, and


                                      B-19


   political conditions. The portfolio may invest in mortgage-backed securities,
   which during times of fluctuating interest rates may increase or decrease
   more than other fixed-income securities. Mortgage-Backed securities are also
   subject to pre-payments. At times, the Fund's investments may represent
   industries or industry sectors that are interrelated or have common risks,
   making it more susceptible to any economic, political, or regulatory
   development or other risks affecting those industries and sectors.

   trends or the factors influencing the Fund's historical or future performance

Portfolio Management Discussion
Pioneer Balanced Fund 12/31/05

The nation's economy grew persistently throughout 2005, producing strong
earnings growth and healthier corporate balance sheets. The economy proved
resilient to the effects of a variety of challenges, from hurricane damage in
the Gulf Coast to sharply rising energy and commodity prices. To head off the
possibility that inflationary pressures would build up as the economy grew, the
U.S. Federal Reserve continued to tighten monetary policy. The Fed raised the
Fed Funds rate eight different times during the calendar year. In the following
interview, Timothy Mulrenan, who is responsible for the equity portfolio of
Pioneer Balanced Fund, and Richard Schlanger, who is responsible for the Fund's
fixed-income portfolio, discuss the markets and the factors that affected
performance.

Q. How did the Fund perform?

A: Class A shares of Pioneer Balanced Fund returned 3.25% at net asset value
   during the 12 months ended December 31, 2005. In comparison, the Standard &
   Poor's 500 Index and the Lehman Brothers Aggregate Bond Index returned 4.91%
   and 2.43%, respectively, over the same period. Additionally, the average
   return of the 650 funds in Lipper's Balanced Fund category was 4.69%.

   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q. What were the principal factors that affected Fund performance?

A: Throughout the 12 months, we overweighted equities, with a target allocation
   of about 64% of Fund assets versus a 60% normal allocation. We invested the
   remaining 36% of assets in fixed income securities. We placed this emphasis
   on stocks because of the favorable earnings environment and our view that
   stocks were likely to produce positive returns during the year. At the same
   time, we were not sure how far the Federal Reserve Board intended to push
   short-term interest rates, and we believed bonds, in general, were fully
   valued in the market.

   The equity market had a positive year, buoyed by positive earnings - profits
   of S&P 500 companies grew approximately 13%. Despite rising short-term
   interest rates and higher commodity prices, long-term interest rates were
   essentially unchanged over the 12 months. Other factors giving support to
   stock valuations included many stock buyback programs, initiated by
   corporations with more cash on their balance sheets, and increasing merger
   and acquisition activity. Despite all these positive factors, stock
   performance was held back by a number of concerns, including fears that
   higher short-term interest rates and high energy costs might undermine future
   corporate profitability.

   The major development in the fixed-income market was the dramatic flattening
   of the yield curve - which reflects the difference in yields between
   short-term and long-term securities. Normally, the yield curve steepens -
   yield differences become greater - the greater the difference in maturity
   between short- and long-term securities. However, the yield curve became so
   flat that it actually partially inverted by the end of the year, a highly
   unusual phenomenon in which 10-year yields actually became slightly lower
   than two-year yields. Despite the efforts of the Federal Reserve to raise
   short-term rates, long-term rates tended to fall or remain stable because of
   strong demand for U.S. Treasuries by international bond investors.

Q. What areas in the equity and fixed income market performed better than
   others?

A: In the equity market, mid-cap stocks did better than either small or
   large-cap stocks, continuing a multi-year run for medium-sized companies. The
   value style of investing slightly outperformed the growth style, but the
   growth style performed somewhat better in the final two months of the year.
   We manage the Fund in a large cap growth style.

   Driven by the dramatic increases in oil and natural gas prices, energy stocks
   were by far the performance leaders in the equity market. On average, energy
   stocks rose by 30%. Utilities also performed relatively well, while consumer
   discretionary stocks - especially in the automotive and media industries -
   lagged.

   In the fixed-income market, long-term investments outperformed short- and
   intermediate-term investments. With a backdrop of rising profits, investment
   grade and high-yield corporate bonds tended to do well. The notable exception
   was among a few fallen angels whose financial problems led to credit rating
   downgrades. Two highly visible examples were General Motors and Ford, both of
   which were downgraded from investment grade to high yield. Among governments,
   Treasuries outperformed mortgages, with long-term Treasuries performing
   especially well.


                                      B-25


Q. What equity investments had the greatest influence on performance?

A: Our overweight position in energy stocks for most of the year and our stock
   selection within the energy sector helped boost performance. Two standout
   selections were National Oilwell Varco, a leading provider of oil field
   equipment, and ENSCO International, a prominent offshore contract driller.
   National Oilwell Varco's stock price rose substantially, driven by robust
   earnings, favorable pricing and a growing backlog of orders. We trimmed the
   position and took profits during the year. ENSCO's stock price appreciated by
   about 40% as the day rates for its oil rigs surged against a backdrop of
   growing demand and a tight supply of the drilling platforms. By the end of
   the year, we had taken some profits, but still held ENSCO, and moved to a
   slight underweight position in energy.

   Our investments in health care also did well. Shares of generic
   pharmaceutical manufacturer IVAX doubled. The company was helped by both an
   impressive pipeline of new drugs approaching market and an acquisition offer
   from a competitor. Amgen, a major biotechnology firm, benefited from strong
   revenue gains across all its product lines and its own promising pipeline of
   new products under development, including prospective drugs for treatment of
   cancer and arthritis. Among the more disappointing positions was our
   investment in Symantec, a leading software security firm. Its stock price
   declined in the second half of the year after the company announced earnings
   that failed to meet expectations. Investors also became concerned about price
   competition in the software security industry and the possibility of new
   competition from Microsoft. The U.K.- based telecommunications services giant
   Vodafone also declined as its profit margins came under pressure because of
   difficulties in operations in Japan and in Europe. Also detracting from
   results was our investment in Family Dollar, a low-price retailer. Lower
   income consumers, who make up a substantial part of Family Dollar's customer
   base, were particularly hard hit by rising energy prices. We eliminated our
   positions in Symantec and in Family Dollar.

Q. What fixed-income investments had the greatest influence on performance?

A: Our positioning on the yield curve did not help. In a period in which
   short-term interest rates were rising and longer-term rates were relatively
   stable, the best positioning would have been a bar-belled approach. That
   would place greater emphasis both on short-term securities - to take
   advantage of rising yields - and on long-term securities to take advantage of
   their high yields and price stability. However, we pursued a
   bulleted-approach with investments throughout the yield curve - including
   intermediate-term securities, which tended to under perform other parts of
   the market. Also holding back results was our investment in bonds of auto
   parts manufacturer Delphi, which filed for bankruptcy protection during the
   year. We had liquidated our position in Delphi prior to the bankruptcy
   filing. During the year, as yields in many part of the market rose, we
   extended duration - a measure of sensitivity to interest rate changes.
   Duration on December 31, 2005, was 4.55 years, compared to 3.98 years six
   months earlier. Average credit quality remained at AA-, although we did
   reduce our exposure to high yield securities. We also cut our mortgage
   position, while raising our allocation to Treasuries and agencies. Mortgages,
   however, still represented the largest sector weighting, at 44.7% of fixed
   income assets at year's end. Treasuries and agencies represented 24% of
   assets, and industrials and utilities were 20%.

Q. What is your investment outlook?

A: We expect positive performance in the equity market if an environment of
   rising profits and strengthening balance sheets continues. We believe two key
   factors should influence the equity markets in 2006: the continued revival of
   corporate capital spending, which already grew by 20% during 2005 and the
   emergence of a performance edge by growth stocks, which have underperformed
   value stocks for several years. As we enter a new year, value stocks have
   reached price levels on a par with growth stocks, and we believe growth
   stocks should begin to outperform because of their greater earnings growth
   potential.

   Given this view, we have added to our positions in companies that can benefit
   from increasing capital spending, with investments in industrials,
   telecommunications equipment and information technology companies. We have
   also reduced our exposure to consumer discretionary stocks, although we
   continue to emphasize consumer staples with their more consistent earnings.

   For the fixed-income market, we anticipate that the Federal Reserve will move
   cautiously because of concerns about high debt levels of consumers. We
   believe the Fed may raise short-term rates two or three times more. We think
   the Fed Funds rate may level off in the range of 4.75% to 5.00%.
   Historically, the Fed has begun lowering rates four to six months after the
   end of its rate-hike cycles, and we believe this may occur again late in
   2006. If that occurs, we expect the short-end and the intermediate parts of
   the yield curve to outperform the long-end, and we would position the
   portfolio accordingly. Because of the tightening labor supply and high energy
   costs, we are carefully watching inflation trends and are prepared to become
   more defensive. We already have established a position in Treasury Inflation
   Protective Securities (TIPS) to guard against the impact of higher inflation.

   When interest rates rise, the prices of fixed income securities in the Fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the Fund will generally rise. Investments in the
   Fund are subject to possible loss due to the financial


                                      B-26


   failure of underlying securities and their inability to meet their debt
   obligations. Prepayment risk is the chance that mortgage-backed bonds will be
   paid off early if falling interest rates prompt homeowners to refinance their
   mortgages. Forced to reinvest the unanticipated proceeds at lower interest
   rates, the Fund would experience a decline in income and lose the opportunity
   for additional price appreciation associated with falling interest rates. The
   portfolio invests in REIT securities, the value of which can fall for a
   variety of reasons, such as declines in rental income, fluctuating interest
   rates, poor property management, environmental liabilities, uninsured damage,
   increased competition, or changes in real estate tax laws.

   Investing in foreign and/or emerging markets securities involves risks
   relating to interest rates, currency exchange rates, economic, and political
   conditions.

   The portfolio may invest in mortgage-backed securities, which during times of
   fluctuating interest rates may increase or decrease more than other
   fixed-income securities. Mortgage-Backed securities are also subject to
   pre-payments. At times, the Fund's investments may represent industries or
   industry sectors that are interrelated or have common risks, making it more
   susceptible to any economic, political, or regulatory developments or other
   risks affecting those industries and sectors.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These opinions should not be relied upon for any other purposes. Past
   performance is no guarantee of future results, and there is no guarantee that
   market forecasts discussed will be realized.

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer AMT-Free Municipal Fund 12/31/05

In the following interview, Portfolio Manager Stephen C. Bauer outlines the
investment environment for tax-free bonds during the Fund's most recent fiscal
year, Fund performance, his investment philosophy and strategy, and his
outlook.

Q. How did the Fund perform during its most recent fiscal year?


A: For the 12-month period ended December 31, 2005, Pioneer AMT-Free Municipal
   Fund's Class A shares produced a 4.81% return; Class B shares returned 4.02%;
   and Class C shares 3.78%, each at net asset value. The Fund's benchmark, the
   Lehman Brothers Municipal Bond Index, returned 3.51% and the average return
   of the Lipper General Municipal Debt Funds category was 3.00%. Lipper is an
   independent monitor of mutual fund performance.


   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q: Will you describe the investing environment for tax-exempt bonds during the
   time period?

A: For the second year in a row, the environment for long-term municipals was
   remarkably stable. The U.S. economy maintained steady Gross Domestic Product
   growth throughout the year, energy prices soared, but inflation was muted.
   Yields of long-term municipals and Treasury securities continue to be low,
   close to their all-time low in June 2003. (The Bond Buyer 40 Municipal Index,
   an industry standard for measuring long-term municipal bond interest rates,
   closed the period at 4.77%.) The trading range for long-term municipals was
   extremely narrow for the period. This was mildly surprising given that the
   Federal Reserve continued to raise short term interest rates aggressively
   throughout 2005, and that most economists had once again predicted that
   long-term rates would increase. Intermediate-term rates rose, but long-term
   rates, where this portfolio is concentrated, were slightly lower during the
   past 12 months. This meant that long-term municipal investors generally
   earned their coupon interest rate, plus some price appreciation (as bond
   yields decline, bond prices rise, and vice versa).

Q. How would you characterize supply and demand for municipal bonds?

A: The year 2005 set a record for total volume of new municipal issues during
   the year, over $400 billion. The volume was much higher than anticipated and
   largely related to tax-free bond refundings, where issuers take advantage of
   declining interest rates and refinance higher yielding bonds at lower rates.

   Though demand from individual investors remained flat during the period,
   tremendous demand for municipal bonds came from property and casualty
   insurance companies. These firms have actually experienced strong profit
   growth during a terrible year for natural disasters in 2005, as they have
   been able to raise their rates and benefit from increased demand from
   businesses and consumers for property and casualty insurance.

Q. Will you restate your philosophy in managing the Fund?


A: My investment philosophy is to stay fully invested in long-term bonds.
   Pioneer AMT-Free Municipal Fund is a long-term fund, and I feel responsible
   to maintain it as such, and not to try to predict the direction or magnitude
   of interest rate changes and make maturity or other investment decisions on
   that basis. At the close of the period, the Fund's average maturity was
   approximately 21 years.


   In addition, I believe that being invested in long-term municipal bonds is a
   sound strategy for two reasons: First, long-term municipal bonds consistently
   yield and more than shorter-term bonds.

   There have been no inverse yield curves in the municipal bond market (i.e.,
   where long-term rates are lower than short-term rates). Of course, the reason
   that longer-term municipal bonds yield more is that they are more volatile
   than bonds of shorter maturity. Greater interest rate risk is the trade-off
   for more total return through the accumulation of higher yield over the long
   term.

   The second reason is that I take a very long-term view of the bond market. I
   rarely make any transactions that I think will pay off only over the short
   term. As I see it, many of the best investment decisions take years to bear
   fruit. This long-term view means that the Fund will generally have a very low
   turnover ratio and reasonably low transaction costs.


                                      B-32


Q. Will you discuss your portfolio strategy during the 12-month period?

A: I pursued two main strategies over the period. First, I sold a number of
   municipal bonds with short call dates. These bonds were purchased
   inexpensively several years ago and had performed well for the Fund. But with
   their call protection running out (at the call date, the issuer can refund
   the proceeds of the bond for cash at "par," the original offering price), the
   price appreciation potential for the bonds was limited. In their place, the
   Fund purchased municipal bonds with more attractive call features. This call
   protection strategy is meant to optimize the Fund's performance
   characteristics and has worked well over the long term.

   Second, during the 12-month period I purchased several par bonds for the
   Fund. Typically these bonds have limited appeal because - in terms of their
   price performance - they may have marginal upside and higher than normal
   downside should interest rates rise. However, the par bonds purchased during
   the period carried high yields and were very attractively priced. Several
   years ago, when California was in the midst of a fiscal crisis and issuing
   billions in debt in order to maintain services, I purchased a number of
   California bonds for the Fund because they were so inexpensive. Now that
   California's economy is performing much better, the state is beginning to
   make progress in dealing with its budget deficit. In light of this, two major
   ratings agencies upgraded California's debt in July 2005 and its bonds have
   been trading extremely strongly. Because the yields on the state's bonds have
   declined in the face of this progress, the Fund took profits on a number of
   California issues during the period.

Q. How is the Fund positioned in terms of credit quality and diversification?

A: Approximately 44% of the Fund's portfolio is rated AAA or the equivalent (the
   highest rating). In addition, the Fund is broadly diversified among 24 states
   and Puerto Rico. For the period, the Fund generally avoided purchasing any
   bonds with ratings lower than AAA. Purchasing lower quality bonds has been a
   popular strategy in the municipal marketplace in recent years, and "spreads"
   - or differences in yield between higher and lower quality municipal bonds -
   have narrowed considerably. At present, I do not believe investors are being
   adequately compensated in additional yield for the risk of buying lower
   quality bonds.

Q. What is your outlook going forward?

A: Every year brings unexpected events that move the market, but at present,
   long-term municipal bonds look very stable. Inflation figures seem modest,
   and it is hard to find economic factors or other trends that might change
   that. With an inverted yield curve in the Treasury market in December 2005
   (where short-term rates were modestly higher than long-term rates), some have
   predicted an economic slowdown in 2006. If this occurs, it would be good news
   for long-term municipal bonds, because such slowdowns tend to reduce
   inflationary pressures. We will be monitoring the progress of the economy and
   markets over the course of the coming year, as well as the actions of the
   incoming Fed chairman Bernanke.


   We believe that Pioneer AMT-Free Municipal Fund continues to be a suitable
   vehicle for long-term investors seeking high income free from federal taxes.



   When interest rates rise, the prices of fixed income securities in the fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the fund will generally rise. Investments in the
   fund are subject to possible loss due to the financial failure of underlying
   securities and their inability to meet their debt obligations. Investing in
   foreign and/or emerging markets securities involves risks relating to
   interest rates, currency exchange rates, economic, and political conditions.
   At times, the fund's investments may represent industries or industry sectors
   that are interrelated or have common risks, making it more susceptible to any
   economic, political, or regulatory developments or other risks affecting
   those industries and sectors.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the fund's historical or future performance
   are statements of the opinion of fund management as of the date of this
   report. These opinions should not be relied upon for any other purposes. Past
   performance is not guarantee of future results, and there is no guarantee
   that market forecasts discussed will be realized.

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer Florida Tax Free Income Fund 1/31/06

Despite rising short-term interest rates during the last six months,
shareholders in Pioneer Florida Tax Free Income Fund earned a positive return.
In the following interview, David Eurkus, a Portfolio Manager and member of the
Pioneer fixed-income team, discusses some of the factors that had an impact on
the Fund's performance over the past six months.

Q. How did the Fund perform during the six-month period ended January 31, 2006?

A: During the six months, Class A shares of Pioneer Florida Tax Free Income Fund
   produced a total return of 0.85% at net asset value. The Fund underperformed
   its benchmark, the Merrill Lynch 1-12 Year Municipal Bond Index, which
   returned 1.16% for the same period. It also fell short of the average 0.90%
   return generated by the funds in the Florida Intermediate Municipal Debt
   Funds Category of Lipper, Inc., an independent monitor of mutual fund
   performance. At the end of the period, the 30-day SEC yield for Class A
   shares was 3.02% or a 4.65% taxable equivalent yield based on the maximum 35%
   federal tax bracket. The Fund had 42 issues with an average quality of AAA.

   Call 1-800-225-6292 or visit for the most recent month-end performance
   results. Current performance may be lower or higher than the performance data
   quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q. What was the investment environment like during the period?

A: In an environment of relatively strong economic growth, the Federal Reserve
   continued to tighten monetary policy, boosting interest rates five times from
   3.25% to 4.50% during the period. The net effect of the Fed's actions was a
   flattening of the yield curve, with short-term yields moving higher and
   longer-term yields remaining stable or declining slightly. In Florida, the
   rate of economic growth was greater than the national average, as solid gains
   in housing, personal income, tourism and international trade resulted in
   relatively low unemployment and added to the stability and strength of the
   Florida economy.

Q. In this environment, what strategies did you use in managing the Fund?

A: The Fund sought to balance the preservation of capital, while increasing
   current income that is exempt from federal income tax and Florida's
   intangible state personal property tax.

   Early in the period, most of the Fund's assets were invested in the short and
   intermediate part of the yield curve. Because we wanted to create a more
   diversified portfolio that would provide more income, we sold some
   short-maturity bonds, then selectively added longer-maturity bonds to the
   Fund. That had the effect of modestly extending the Fund's duration, or price
   sensitivity to interest-rate changes. It also boosted the Fund's income
   stream. When adding investments to the portfolio, we favored high-quality
   municipal securities in sectors that are essential to the growth of the
   Florida economy. These included health care and hospitals, public power,
   energy, transportation and education. We based our investment decisions on
   the fundamental attributes of each security, focusing on each bond's yield,
   liquidity, credit rating, call protection, issuer diversification and
   relative value.

Q. What effect did the portfolio changes have on performance?

A: To build upon my previous answer, Pioneer took over the assets from the
   AmSouth Florida Tax-Exempt Fund in late September 2005 when we sought a more
   flexible portfolio that could boost income by choosing longer-term bonds.
   That move enhanced performance. However, the Fund's relatively short duration
   at the beginning of the period resulted in a modest amount of
   underperformance.

Q. What is your outlook for the next six months?

A: The expansion in the national economy appears solid. Core inflation is
   relatively low, and longer-term inflation expectations appear to be
   contained. The Fed has indicated that it may be near the end of its
   rate-raising cycle, and so we may see fewer interest-rate hikes in the next
   several months. While we expect the overall business expansion in Florida to
   continue, it is likely that some sectors, such as housing, will slow down.
   The damage caused by the recent rash of hurricanes has presented the state
   and counties with big challenges. However, reconstruction of the damaged
   areas should continue to help solidify economic growth. In managing the Fund,
   we plan to remain fully invested and to maintain our diversification strategy
   among the broad range of Florida's municipal bond issuers.


                                      B-38


   When interest rates rise, the prices of fixed income securities in the Fund
   will generally fall. Conversely, when interest rates fall, the prices of
   fixed income securities in the Fund will generally rise. Investments in the
   Fund are subject to possible loss due to the financial failure of underlying
   securities and their inability to meet their debt obligations. Investing
   primarily in the securities issued by Florida and its municipalities makes
   the Fund more vulnerable to unfavorable developments in Florida than are
   funds that invest in municipal securities of many states. The Fund invests in
   a limited number of securities and, as a result, the Fund's performance may
   be more volatile than the performance of other funds holding more securities.
   At times, the Fund's investments may represent industries or industry sectors
   that are interrelated or have common risks, making it more susceptible to any
   economic, political, or regulatory developments or other risks affecting
   those industries and sectors.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These statements should not be relied upon for any other purposes.
   Past performance is no guarantee of future results, and there is no guarantee
   that market forecasts discussed will be realized.

shares, when redeemed, may be worth more or less than their original cost.

Class C shares held for less than one year are also subject to a 1% contingent
deferred sales charge (CDSC). The performance of Class C shares does not
reflect the 1% front-end sales charge in effect prior to February 1, 2004. If
you paid a 1% sales charge, your returns would be lower than those shown above.
"If Held" results represent the percent change in net asset value per share.
Returns would have been lower had sales charges been reflected. All results are
historical and assume the reinvestment of dividends and capital gains. Other
share classes are available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer Research Fund 12/31/05

In the following interview, John Peckham, U.S. Equity Research Coordinator and
member of the Pioneer Research Fund team, discusses the factors that influenced
performance for the twelve months ended December 31, 2005.

Q. How did the US stock market perform in 2005?

A: In a year that was notable for the variety of potential obstacles to market
   performance - including rising interest rates, a spike in energy prices, and
   September's Gulf Coast hurricanes - the U.S. market nonetheless produced
   solid returns on the strength of steady economic growth and impressive
   corporate earnings results. This generally positive environment, which lacked
   the speculative element that often characterizes sharply rising markets,
   provided a favorable backdrop for our bottom-up, research-based approach.

Q. How did the Fund perform in relation to its benchmark and peer group?

A: Class A shares of the Fund produced a total return of 7.20% at net asset
   value during the 12-month period ended December 31, 2005, outperforming the
   4.91% of the Fund's benchmark, the S&P 500 Index. The Fund also beat the
   4.84% average return of the 890 funds in the Fund's Lipper Large-Cap Core
   category during the annual period.

   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

   Naturally, past performance is no guarantee of future results. Having said
   that, we believe the Fund's strong showing in both 2004 and 2005 reflects the
   effectiveness of our investment process. We manage the portfolio with an
   emphasis on individual stock picking. We do not strive to predict the outlook
   for the economy, the market, or individual sectors, and we therefore keep the
   Fund's sector weightings as close to the S&P 500 as possible. The result is
   that the Fund's performance is almost entirely the result of the quality of
   our stock selection. And during 2005, we were successful in this endeavor: of
   the 25 subsectors we track, our stock picks outperformed the benchmark in 19.

Q. What factors helped performance during the reporting period?

A: We added value through our stock selection in the health care, energy and
   consumer discretionary sectors. In health care, three stocks provided
   outstanding returns for the Fund.

   Cubist Pharmaceuticals, a biotechnology company that developed a drug to
   treat hospital infections, returned over 80% for the year. Vertex
   Pharmaceuticals also climbed, as promising studies for its hepatitis drug led
   investors to boost their future earnings estimates for the company. And our
   position in IVAX Pharmaceuticals, a generic drug maker, was taken over by
   Israel's Teva Pharmaceuticals. Health care was a potentially challenging area
   in which to invest during 2005, and so we are pleased that we were able to
   add value in this sector.

   Energy was the strongest performing sector in the market during the year, as
   the rising prices of oil and gas led to robust profit growth for companies in
   the industry. A number of our stock picks did well, but the best performer
   was Premcor, an independent refiner that was purchased at a premium by
   Valero. Among large, diversified oil and gas companies, positive
   contributions came from ConocoPhillips and Occidental Petroleum, both of
   which outperformed. Weatherford International and Noble Corporation also
   benefited from the strength in their markets: equipment/services and
   drilling, respectively. It was relatively easy to find strong performing
   energy stocks during 2005, but we are gratified that our research process led
   us to invest in stocks that, as a group, outperformed the sector as a whole.

   Consumer discretionary stocks, which had a difficult year in 2005, were also
   a source of out performance for the Fund. In the automotive sector, we were
   helped by our avoidance of Ford and General Motors, both of which performed
   very poorly. The Fund instead owned Johnson Controls, an auto components
   manufacturer with a diversified customer base that provided exposure to the
   strong growth of the Asian car makers. In retail, our decision to own JC
   Penney and Target paid off as both executed well and posted gains in a year
   when retailers, as a group, provided only a flat return.


                                      B-44


Q. What elements of your positioning detracted from performance?

A: Given the strength of our stock selection during the year, there were few
   meaningful detractors to performance. Our picks underperformed in six of the
   25 industry subsectors, but in none of these was the shortfall meaningful.
   One detractor of note was Avon Products, which struggled with its U.S. and
   international sales efforts. Our performance was also disappointing in
   telecommunications services, where the Fund's investment in Vodafone lost
   ground due to the company's issues with increasing competition in Europe and
   its difficulty growing market share in Japan. Another notable misstep was our
   investment in Symantec, a software company that experienced
   lower-than-expected sales for its virus and security software.

Q: Financials and technology are the two largest sectors in the S&P 500. How
   effective was your stock selection in these industries?

A: In financials, our stock picks outperformed the financial stocks in the
   benchmark by a little more than two percentage points. The most significant
   drivers of performance were our positions in the investment banks/brokers
   Merrill Lynch and Goldman Sachs, both of which benefited from the strong
   market for initial public offerings as well as rising merger and acquisition
   activity. In bank stocks, where it was difficult to make money due to the
   interest rate environment, we benefited from our strategy of sticking to
   reasonably-priced stocks with diversified business mixes and yield curve
   exposures below the industry average. Such holdings included Bank of America,
   which was helped by the successful integration of Fleet Bank, as well as
   Wachovia Bank.

   In technology, we generated slight out performance. While Symantec hurt
   performance in software and services, we offset this through the out
   performance we generated in the semiconductor sector. Here, Texas Instruments
   benefited from the strong demand for the products in which its chips are
   used, including cell phones and high definition TVs. In hardware, the Fund's
   position in Hewlett-Packard performed well after the appointment of a new CEO
   raised hopes that its business will undergo the restructuring investors had
   been demanding. SanDisk, whose sales were boosted by the rapidly growing
   demand for flash memory, also made a positive contribution to Fund
   performance.

Q. Do you have any closing thoughts for shareholders?

A: While the year ahead is likely to be more volatile than 2005, we will
   continue to look past short-term market noise to identify fundamentally
   sound, reasonably valued companies. Given the favorable growth environment
   and the fact that the market as a whole is reasonably valued, we believe the
   environment will remain fertile for our bottom-up, research-driven investment
   process.

   At times, the Fund's investments may represent industries or industry sectors
   that are interrelated or have common risks, making it more susceptible to any
   economic, political, or regulatory developments or other risks affecting
   those industries and sectors.

   Any information in this shareholder report regarding market or economic
   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These opinions should not be relied upon for any other purposes. Past
   performance is no guarantee of future results, and there is no guarantee that
   market forecasts discussed will be realized.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

POP returns reflect deduction of maximum 5.75% sales charge. NAV results
represent the percent change in net asset value per share. Returns would have
been lower had sales charges been reflected. All results are historical and
assume the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

The performance of the Class A and Class B shares of the Fund includes the
performance of AmSouth Select Equity Fund's Class A and Class B shares prior to
the reorganization, which has been restated to reflect differences in any
applicable sales charges (but not differences in expenses). Pioneer Focused
Equity Fund was created through the reorganization of AmSouth Select Equity
Fund on September 23, 2005. If the performance had been adjusted to reflect all
differences in expenses, the performance of the Fund would be lower. All
results are historical and assume the reinvestment of dividends and capital
gains. Other share classes are available for which performance and expenses
will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes
that a shareowner would pay on Fund distributions or the redemption of Fund
shares.

PORTFOLIO MANAGEMENT DISCUSSION
Pioneer Focused Equity Fund 1/31/06

In the following interview, portfolio managers Neil Wright, Janna Sampson and
Peter Jankovskis discuss the factors that influenced Pioneer Focused Equity
Fund's performance for the semiannual period ended January 31, 2006. Pioneer
Focused Equity Fund was created through the reorganization of AmSouth Select
Equity Fund on September 23, 2005.

Q: Can you characterize the market environment for the Fund over the six-month
   period ended January 31, 2006?

A: The semiannual period saw generally modest equity returns with the notable
   exception of energy and other commodity-related stocks. At the end of August
   2005, Hurricane Katrina devastated the Gulf Coast, and this was followed a
   few weeks later by Rita. One of the results of this catastrophic hurricane
   season was a significant short-term disruption in the U.S. oil supply. That
   resulted in soaring energy prices, with a barrel of crude oil briefly topping
   the $70 mark, as compared to prices in the $30 range two years earlier. Other
   commodities, such as paper and metals, followed suit. As a result, commodity
   producing companies generally experienced substantial earnings increases
   during the period, while earnings - and share prices - in industries that
   rely on commodities in the manufacture or delivery of their products suffered
   from increased costs.

Q. How did the Fund perform in this environment?

A: Class A shares of the Fund returned (3.03)% at net asset value from July 31,
   2005, through January 31, 2006, versus 4.67% for the Standard & Poor's 500
   Index, the Fund's unmanaged benchmark. The Fund's long-term investment
   strategy of focusing on companies with strong brands constrained performance
   over a period in which market leadership was highly concentrated among
   commodity producers. In addition, many of the companies in our investment
   universe are heavy commodity consumers.

   Call 1-800-225-6292 or visit www.pioneerinvestments.com for the most recent
   month-end performance results. Current performance may be lower or higher
   than the performance data quoted.

   The performance data quoted represents past performance, which is no
   guarantee of future results. Investment return and principal value will
   fluctuate, and shares, when redeemed, may be worth more or less than their
   original cost.

Q. Can you outline the Fund's overall investment approach?

A: Our investment universe is approximately 150 mid- and large capitalization
   companies with dominant market share positions that are supported by some
   barrier to entry such as a well-known brand name. Within our universe, we
   employ an actively managed, stock-by-stock approach to identify companies
   that we believe are trading at discounts to their long-term value. The result
   is a portfolio of 20 to 25 leading "market power" companies whose stock
   prices we believe are undervalued. We believe that a portfolio constructed in
   this fashion has the potential to outperform the broader market over a
   complete market cycle, with less volatility.

Q. Can you discuss what helped and hurt performance of the Fund over the
   period?

A: Unfortunately, the universe of companies from which we select investments was
   out of favor, and that was reflected in the Fund's results over the six
   months. We typically do not invest in the energy sector, and during the
   period we had no exposure to energy, which was by far the best performing
   sector. In addition, we made a decision to avoid the financial sector because
   we thought the Federal Reserve would continue to raise rates on the short
   end, and we expected longer-term rates to rise along with commodity prices.
   However, long-term rates were stable as the market did not perceive inflation
   as a threat, and in retrospect exposure to financials would have helped
   performance.

   Because one of our principal areas of focus is on companies with strong
   brands, we are generally overweighted versus the broad market in the
   consumer-oriented sectors, which underperformed during the semiannual period.
   At the end of January, the consumer discretionary and consumer staples
   sectors comprised over 36% and 21%, respectively, of the Fund. Our biggest
   holding in this area and one of our better performers was McDonald's, a
   bellwether consumer discretionary stock. McDonald's managed to grow sales and
   maintain strong earnings on the basis of well received new products and
   promotions. In addition, McDonald's has taken steps to reduce its paper
   costs, by reducing the size of the containers used to deliver food to
   consumers.

   A number of holdings were affected more decisively during the period by
   higher paper costs, including newspaper publisher Tribune. A tepid
   advertising environment also contributed to weaker results for publishers.
   Among consumer staples, Kimberly Clark was hit especially hard by the
   increased cost of paper. The company relies heavily on sales of paper-based
   products such as diapers and facial tissues, and recently sold its paper
   mill, making its earnings more subject to fluctuations in the price of that
   commodity. In


                                      B-50


   addition, Kimberly Clark incurred significant research costs during the
   period, which acted to lower short-term earnings, but which we believe will
   serve the company well in the longer run.

   The Fund is also overweight the industrial sector, which stood at over 21% of
   assets at the end of January. The Fund's largest holding in this area is
   Automatic Data Processing (ADP) the leading provider of payroll processing
   services to employers. We expected the company's shares to perform well given
   both the growth in U.S. employment and rising short-term interest rates,
   which provide a boost to earnings on cash held by ADP pending its
   disbursement to employees of its client companies. However, concerns about
   economic growth and the sustainability of recent employment gains held back
   the performance of ADP's stock during the period.

   As we are long-term investors in a fairly concentrated number of companies,
   turnover in the portfolio is typically low. The biggest change among our
   holdings during the period was the elimination of Wal-Mart Stores from the
   portfolio. Our decision was made in view of a change in banking regulations
   that took effect in January of 2006 and that has resulted in a doubling of
   minimum credit card payments for millions of consumers. While the change has
   not yet been reflected in the company's business results or share price
   performance, we believe it has the potential to hurt Wal-Mart more than its
   peers.

Q. How are you positioning the Fund going forward?

A: We expect energy prices and commodity prices in general to moderate, giving
   the companies on which we focus an opportunity gradually to raise prices and
   restore profitability. Historically, the Fund's universe of "market power"
   companies has traded at a premium to the overall market based on such
   valuation measures as price-earnings ratios, which indicate how much
   investors are willing to pay per dollar of a company's earnings. However,
   many of the companies we hold are currently priced at below-market price
   earnings ratios and dramatically below their long-term average valuations. We
   believe the Fund is well positioned for the next phase of the market cycle,
   even if commodity prices remain near their current levels. The biggest risk
   to this outlook is a sharp increase in energy prices during the first quarter
   of 2006, which we do not view as likely.

   Going forward, we will continue to use intensive fundamental research to
   target leading companies benefiting from competitive barriers that help
   protect their market shares and profits, with a focus on those companies that
   are selling at reasonable valuations. Our goal remains to outperform the
   broader market over the long term, with less short-term volatility.

   The Fund invests in a limited number of securities and, as a result, the
   Fund's performance may be more volatile than the performance of other funds
   holding more securities. Investing in foreign and/or emerging markets
   securities involves risks relating to interest rates, currency exchange
   rates, economic, and political conditions. At times, the Fund's investments
   may represent industries or industry sectors that are interrelated or have
   common risks, making it more susceptible to any economic, political, or
   regulatory developments or other risks affecting those industries and
   sectors.

   trends or the factors influencing the Fund's historical or future performance
   are statements of the opinion of Fund management as of the date of this
   report. These statements should not be relied upon for any other purposes.
   Past performance is no guarantee of future results, and there is no guarantee
   that market forecasts discussed will be realized.

(a)   Reflects estimated expenses of the combined fund. Expense adjustments
      are based on the higher or lower expense structure (e.g., custodian
      fees, printing fees and other expenses) of the combined fund.

(b)   Expense adjustments conform to the combined fund's contracts with
      affiliated parties. Expense adjustments are based on the higher or lower
      contractual expense structure (e.g., transfer agency fees, Rule 12b-1
      distribution and service fees, and administrative expenses), as well
      as the expense characteristics of the combined fund and its share
      classes (e.g., net assets, average shareholder account size and number
      of shareholder accounts), which differs from those of each fund on an
      uncombined basis and also differs from any predecessor fund.

(c)   Includes costs of the reorganization.

(d)   The predecessor fund to Pioneer Florida Tax Free Income Fund charged a
      shareholder servicing (non-Rule 12b-1) fee that ranged from 0.15% up to
      0.25% of that predecessor fund's average daily net assets, depending on
      the share class. After the closing of the reorganization on September 23,
      2005, the predecessor fund's shareholder servicing fees terminated and
      Pioneer Florida Tax Free Income Fund adopted plans of distribution
      pursuant to Rule 12b-1 ("Rule 12b-1 Plans") with respect to its Class A,
      Class B and Class C shares providing for fees payable at the annual rates
      of 0.25%, 1.00% and 1.00% of the fund's average daily net assets
      attributable to these respective classes. Pursuant to the Pioneer Rule
      12b-1 Plans, each fund's Class B and Class C shares pay a combined
      distribution and service fee of 1.00%, of which 0.75% is paid for
      distribution services and 0.25% is paid for shareholder services. The pro
      forma adjustments reflect the Rule 12b-1 Plans of the combined fund.

Pioneer AMT-Free Municipal Fund

PRO FORMA NOTES TO COMBINING FINANCIAL STATEMENTS
12/31/05
(Unaudited)

1.    Description of the Fund

Pioneer AMT-Free Municipal Fund (the Fund) is one of eight series of portfolios
comprising Pioneer Series Trust II, a Delaware statutory trust registered under
the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund is the successor to the Safeco Municipal Bond Fund,
Inc. Safeco Municipal Bond Fund transferred all of its net assets in exchange
for the Fund's Investor Class shares on December 10, 2004 pursuant to an
agreement and plan of reorganization (the "reorganization" which was approved by
the shareholders of Safeco Municipal Bond Fund on December 8, 2004). The Fund
had no assets or liabilities prior to the reorganization. Accordingly, the
reorganization, which was a tax-free exchange, had no effect on the Fund's
operations. The investment objective of the Fund is to seek a high level of
current income exempt from federal income tax as is consistent with the relative
stability of capital.

The Trustees have authorized the issuance of five classes of shares of the Fund.
The Fund offers five classes of shares designated as Class A, Class B, Class C,
Class Y and Investor Class shares. The Fund is not offering additional Investor
Class shares except in connection with the reinvestment of dividends on the
Fund's outstanding Investor Class shares. Each class of shares represents 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 shareowners, respectively. There is no distribution
plan for Class Y and Investor Class shares.

2.    Basis of Combination

The accompanying pro forma combining financial statements, and related notes,
are presented to show the effect of the proposed acquisition (the "acquisition")
of Pioneer Florida Tax Free Income Fund by the Fund, as if such acquisition had
taken place as of December 31, 2005.



Under the terms of an Agreement and Plan of Reorganization (the
"Reorganization") between these two Funds, the combination of the Fund and
Florida Tax Free Income 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. The acquisition will be accomplished by an
acquisition of the net assets of Pioneer Florida Tax Free Income Fund in
exchange for shares of the Fund at their net asset values. The accompanying
schedules of investments, statements of assets and liabilities and the related
statements of operations of the Fund and Pioneer Florida Tax Free Income Fund
have been combined as of and for the most recent fiscal year ended December 31,
2005. Following the acquisition, the Fund will be the accounting survivor. The
Advisor has agreed to pay 50% of the expenses associated with the
reorganizations, and AMT-Free Municipal Fund and Florida Tax Free Income Fund
will equally bear the remaining costs of the reorganization. These costs are
reflected in the proforma financial statements.

These pro forma financial statements and related notes should be read in
conjunction with the financial statements of the Fund and Pioneer Florida Tax
Free Income Fund included in their annual reports to shareowners dated December
31, 2005 and July 31, 2005, respectively. Adjustments have been made to
eliminate duplicate expenses that would not have been incurred if the merger had
taken place on December 31, 2005, and to reflect the expenses for contractual
rates that will exist after the merger, based on actual contract rates that
exist for the AMT-Free Municipal Fund at December 31, 2005.

3.    Security Valuation



Security  transactions  are recorded as of trade date.  Securities are valued at
prices supplied by independent pricing services,  which consider such factors as
Treasury spreads, yields, maturities and ratings. Valuations may be supplemented
by dealers and other  sources,  as required.  Securities  for which there are no
other readily  available  market  quotations  are valued at their fair values as
determined  by, or under the  direction of the Board of Trustees.  The Fund also
may use the fair value of a security  including  a  non-U.S.  security  when the
closing  market price on the principal  exchange where the security is traded no
longer reflects the value of the security. Temporary cash investments are valued
at amortized cost.

Discount and premium on debt securities are accreted or amortized,  respectfully
daily into interest  income on a  yield-to-maturity  basis with a  corresponding
increase  or  decrease  in the cost basis of the  security.  Interest  income is
recorded on the accrual basis.



4.    Capital Shares

The pro forma net asset value per share assumes the issuance of shares of the
Fund that would have been issued at December 31, 2005, in connection with the
proposed acquisition. The number of shares assumed to be issued is equal to the
net asset value of



shares of Pioneer Florida Tax Free Income Fund, as of December 31, 2005, divided
by the net asset value per share of the Fund's shares as of December 31, 2005.
The pro forma number of shares outstanding, by class, for the combined Fund

5.    Federal Income Taxes

Each Fund has elected to be taxed as a "regulated investment company" under the
Internal Revenue Code. After the acquisition, it will continue to be 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 shareowners. Therefore, no
federal income tax provision is required.

The identified cost of investments for these Funds is substantially the same for
both financial and federal income tax purposes. The cost of investments will
remain unchanged for the combined Fund.

(*) Filed herewith as Exhibit A to the Proxy Statement and Prospectus included
as Part A of this Registration Statement.

(**)  Filed herewith.


ITEM 17. UNDERTAKINGS.

(1) The undersigned Registrant agrees that prior to any public reoffering of the
securities registered through the use of a prospectus which is part of this
Registration Statement by any person or party which is deemed to be an
underwriter within the meaning of Rule 145(c) of the 1933 Act, the reoffering
prospectus will contain the information called for by the applicable
registration form for the reofferings by persons who may be deemed underwriters,
in addition to the information called for by the other items of the applicable
form.

(2) The undersigned Registrant agrees that every prospectus that is filed under
paragraph (1) above will be filed as part of an amendment to the Registration
Statement and will not be used until the amendment is effective, and that, in
determining any liability under the 1933 Act, each post-effective amendment
shall be deemed to be a new registration statement for the securities offered
therein, and the offering of the securities at that time shall be deemed to be
the initial bona fide offering of them.

(3) The undersigned Registrant agrees that it shall file a final executed
version of the legal and consent opinion as to tax matters as an exhibit to the
subsequent post-effective amendment to its registration statement on Form N-14
filed with the SEC upon the consummation of the reorganization contemplated by
this Registration Statement on Form N-14.

(4) Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, 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 such
indemnification is against public policy as expressed in the 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 director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, 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 Act and will be governed by the final adjudication of
such issue.

     Pursuant to the requirements of the Securities Act of 1933, as amended,
