                               PIONEER BOND FUND
           (each, a "Pioneer Fund" and together, the "Pioneer Funds")

           The address and telephone number of each Pioneer Fund is:

                                60 State Street
                          Boston, Massachusetts 02109
                                 1-800-225-6292



To the Shareholders of Pioneer Government Income Fund:

     The Board of Trustees of your fund has approved the reorganization of your
fund (the "Acquired Fund") with Pioneer Bond Fund (the "Acquiring Fund") after
considering the recommendation of Pioneer Investment Management, Inc., the
investment manager to your fund and concluding that the reorganization would be
in the best interests of your fund.

      Following is a brief description of certain aspects of the Reorganization:

      o     Your fund and the Acquiring Fund have similar investment objectives
            and both funds invest primarily in investment grade debt securities.
            However, the Acquiring Fund may invest in a significantly broader
            range of debt securities than your fund. Whereas your fund invests
            at least 80% of its assets in U.S. government securities, the
            Acquiring Fund invests at least 80% of its assets in investment
            grade debt securities, including corporate bonds and other debt
            instruments in addition to U.S. government securities. The Acquiring
            Fund also may invest up to 20% of its net assets in debt securities
            rated below investment grade (known as "junk bonds"). Accordingly,
            as a result of the Reorganization, shareholders of the Acquired
            Fund, as shareholders of the combined fund, will be exposed to
            greater investment risk in general, including greater credit
            exposure, and may experience greater volatility.

      o     The combined fund will pay a lower management fee rate than the
            management fee rate paid by your fund.

      o     The expense ratio of each class of shares of the combined fund is
            expected to be lower than the expense ratio of the corresponding
            class of shares of your fund.

      o     The historical performance of the Acquiring Fund was generally
            higher than the historical performance of your fund.

      o     Your fund has not achieved a sufficient size to allow for more
            efficient operations and is not likely to do so in the future. The
            combined fund may be better positioned to attract assets than your
            fund. The larger asset size of the combined fund may allow it,
            relative to your fund, to reduce per share expenses as fixed
            expenses will be shared over a larger asset base.

      o     The reorganization generally is not expected to have federal income
            tax consequences for shareholders.

      The reorganization is expected to occur on or about March 11, 2016. No
commission, redemption fee or other transactional fee will be charged as a
result of the reorganization.

     The reorganization does not require shareholder approval, and you are not
being asked to vote. We do, however, ask that you review the enclosed
information statement/prospectus, which contains information about the
Acquiring Fund, outlines the differences between your fund and the Acquiring
Fund, and provides details about the terms and conditions of the
reorganization.

     The Board of Trustees of your fund has unanimously approved your fund's
reorganization and believes the reorganization is in the best interests of your
fund.

If you have any questions, please call 1-800-225-6292.

                 Sincerely,

                 Christopher J. Kelley

     This combined information statement/prospectus, dated [______________],
2015 (the "Information Statement/Prospectus"), is being furnished to
shareholders of Pioneer Government Income Fund (the "Acquired Fund") in

Background to the Reorganization

     Pioneer Investment Management, Inc. ("Pioneer"), your fund's investment
adviser, recommended the reorganization of your fund with the Acquiring Fund
(the "Reorganization") for a number of reasons, including:

     o     Your fund and the Acquiring Fund have similar investment objectives
           to provide current income and both funds invest primarily in
           investment grade debt securities. However, the Acquiring Fund may
           invest in a significantly broader range of debt securities than your
           fund.

     o     The combined fund will pay a lower management fee rate than your
           fund. The expense ratio of each class of shares of the combined fund
           is expected to be lower than the expense ratio of the corresponding
           class of shares of your fund.

     o     The historical performance of the Acquiring Fund was generally
           higher than the historical performance of your fund.

     o     Your fund has not achieved a sufficient size to allow for more
           efficient operations and is not likely to do so in the future. The
           combined fund may be better positioned to attract assets than your
           fund. The larger asset size of the combined fund may allow it,
           relative to your fund, to reduce per share expenses as fixed
           expenses will be shared over a larger asset base.

     At a meeting held on November 10, 2015, the Board of Trustees of the
funds unanimously approved the Reorganization of your fund. The Reorganization
of your fund is not subject to approval by the shareholders of your fund.

                                       3


How will the Reorganization work?

      o     The Reorganization is scheduled to occur on or about March 11,
            2016, but may occur on such later date as the parties may agree in
            writing (the "Closing Date").

      o     Your fund will transfer all of its assets to the Acquiring Fund, and
            the Acquiring Fund will assume all of the Acquired Fund's
            liabilities.

      o     The Acquiring Fund will issue Class A, Class C and Class Y shares to
            your fund in amounts equal to the aggregate net asset value of your
            fund's Class A, Class C and Class Y shares, respectively.

      o     Shares of the Acquiring Fund will be distributed to you in
            proportion to the relative net asset value of your holdings of
            shares of each class of the Acquired Fund on the Closing Date.
            Therefore, upon completion of the Reorganization, you will hold
            shares of the corresponding class of the Acquiring Fund with the
            same aggregate net asset value as your holdings of shares of each
            class of the Acquired Fund immediately prior to the Reorganization.
            The net asset value attributable to a class of shares of each fund
            will be determined using the Pioneer Funds' valuation policies and
            procedures. Each fund's valuation policy and procedures are
            identical.

      o     No sales load, contingent deferred sales charge, commission,
            redemption fee or other transactional fee will be charged as a
            result of the Reorganization. After the Reorganization, any
            contingent deferred sales charge that applied to your Class A or
            Class C shares of the Acquired Fund at the time of the
            Reorganization will continue to apply for the remainder of the
            applicable holding period at the time of the Reorganization. In
            calculating any applicable contingent deferred sales charge, the
            period during which you held your shares will be included in the
            holding period of the shares you receive as a result of the
            Reorganization.

      o     The Reorganization generally is not expected to result in income,
            gain or loss being recognized for federal income tax purposes by
            either fund or by the shareholders of either fund.

      o     In approving the Reorganization, the Board of Trustees of each 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, or Pioneer Funds Distributor,
            Inc., the Pioneer Funds' principal underwriter and distributor
            ("PFD") (the "Independent Trustees"), has determined that the
            Reorganization is in the best interest of each fund and will not
            dilute the interests of shareholders. The Trustees have made this
            determination based on factors that are discussed below.

     In addition to the Class A, Class C and Class Y shares to be issued in the
Reorganization, the Acquiring Fund also offers other classes of shares. This
Information Statement/Prospectus relates only to the Class A, Class C and Class
Y shares to be issued in the Reorganization.

What was the basis of the Trustees' determination that the Reorganization was
in the best interests of your fund?

     The Board of Trustees believes that reorganizing your fund with the
Acquiring Fund offers you a number of potential benefits. These potential
benefits and considerations include:

      o     Your fund and the Acquiring Fund have similar investment objectives
            (to provide current income) and both funds invest primarily in
            investment grade debt securities. However, the Acquiring Fund may
            invest in a significantly broader range of debt securities than your
            fund, including corporate bonds and other debt instruments in
            addition to U.S. government securities. The Acquiring Fund also may
            invest up to 20% of its net assets in debt securities rated below
            investment grade (known as "junk bonds").

      o     Your fund has not achieved a sufficient size to allow for more
            efficient operations and is not likely to do so in the future. The
            combined fund may be better positioned to attract assets than your
            fund. The larger asset size of the combined fund may allow it,
            relative to your fund, to reduce per share expenses as fixed
            expenses will be shared over a larger asset base.

      o     The expense ratio of each class of shares of the combined fund is
            expected to be lower than the expense ratio of the corresponding
            class of shares of your fund.

      o     The combined fund will pay a lower management fee rate than the
            management fee rate paid by your fund.

      o     The historical performance of the Acquiring Fund was generally
            higher than the historical performance of your fund.

What are the federal income tax consequences of the Reorganization?

     As a condition to the closing of the Reorganization, the funds must
receive an opinion of Morgan, Lewis & Bockius LLP to the effect that the
Reorganization will constitute a "reorganization" within the meaning of Section
368(a) of the Code. Accordingly, subject to the limited exceptions described
below under the heading "Tax Status of the Reorganization," it is expected that
neither you nor your fund will recognize gain or loss as a direct result of the
Reorganization, and that the aggregate tax basis of the shares that you receive
in the

                                       4


Reorganization will be the same as the aggregate tax basis of the shares that
you surrender in the Reorganization. In addition, the holding period of shares
you receive in the Reorganization will include the holding period of the shares
that you surrender in the Reorganization, provided that you held those shares
as capital assets on the date of the Reorganization. However, in accordance
with the Pioneer Funds' policy that each Pioneer Fund distributes its
investment company taxable income (computed without regard to the
dividends-paid deduction), net tax-exempt income and net capital gains for each
taxable year (in order to qualify for tax treatment as a regulated investment
company and avoid federal income tax thereon at the fund level), your fund will
declare and pay a distribution of such income and gains to its shareholders
shortly before the Reorganization. Such distribution may affect the amount,
timing or character of taxable income that you realize in respect of your fund
shares. For more information, see "Tax Status of the Reorganization" on page
32 of the Information Statement/Prospectus. The Pioneer Fund with which the
Acquired Fund is being reorganized may make a comparable distribution to its
shareholders shortly before the Reorganization. Additionally, following the
Reorganization, the Acquiring Fund will continue to make distributions
according to its regular distribution schedule. You will generally need to pay
tax on those distributions even though they may include income and gains that
were accrued and/or realized before you became a shareholder of the Acquiring
Fund.

Who bears the expenses associated with the Reorganization?

     Each fund will bear approximately 25% of the expenses incurred in
connection with the Reorganization, including expenses associated with the
preparation, printing and mailing of any shareholder communications (including
this Information Statement/Prospectus), any filings with the SEC and other
governmental agencies in connection with the Reorganization, audit fees and
legal fees ("Reorganization Costs"). Pioneer will bear the remaining 50% of the
Reorganization Costs. It is estimated that these expenses in the aggregate will
not exceed $125,000, of which each fund will bear approximately $31,250.

    REORGANIZATION OF PIONEER GOVERNMENT INCOME FUND WITH PIONEER BOND FUND

SUMMARY

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

     The Board of Trustees of your fund has approved the Reorganization of your
fund with the Acquiring Fund. Each fund is managed by Pioneer and has similar
investment policies, but there are certain differences between the funds,
including:

      o     The investment objectives of your fund and the Acquiring Fund are
            similar, but not identical. Your fund's investment object is current
            income. The Acquiring Fund's investment objective is current income
            from an investment grade portfolio with due regard to preservation
            of capital and prudent investment risk. The Acquiring Fund also
            seeks a relatively stable level of dividends.

      o     Your fund and the Acquiring Fund both invest primarily in investment
            grade debt securities. However, the Acquiring Fund may invest in a
            significantly broader range of debt securities than your fund. Your
            fund invests at least 80% of its assets in U.S. government
            securities. In contrast, the Acquiring Fund invests at least 80% of
            its assets in investment grade debt securities, including corporate
            bonds and other debt instruments in addition to U.S. government
            securities. The Acquiring Fund also may invest up to 20% of its net
            assets in debt securities rated below investment grade (known as
            "junk bonds"). Accordingly, as a result of the Reorganization, the
            Acquired Fund's shareholders, as shareholders of the combined fund,
            will be exposed to greater investment risk in general, including
            greater credit exposure, and may experience greater volatility.

     The tables below compare certain features of your fund to the features of
the Acquiring Fund that will be in effect upon completion of the
Reorganization. In the table below, if a row extends across the entire table,
the policy disclosed applies to both your fund and the Acquiring Fund.

Investment grade  A debt security is considered investment grade if it is:
securities        o   Rated BBB or higher at the time of purchase by Standard & Poor's Financial Services LLC;
                  o   Rated the equivalent rating by a nationally recognized statistical rating organization; or
                  o   Determined to be of equivalent credit quality by Pioneer

                  Securities in the lowest category of investment grade (i.e., BBB) are considered to have speculative
                  characteristics.

Debt Rating      For purposes of the fund's credit quality policies, if a security receives different ratings from nationally
considerations   recognized statistical rating organizations, the fund will use the rating chosen by the portfolio manager as
                 most representative of the security's credit quality. The ratings of nationally recognized statistical rating
                 organizations represent their opinions as to the quality of the securities that they undertake to rate and may
                 not accurately describe the risks of the securities. A rating organization may have a conflict of interest with
                 respect to a security for which it assigns a quality rating. In addition, there may be a delay between a change
                 in the credit quality of a security or other asset and a change in the quality rating assigned to the security or
                 other asset by a rating organization. If a rating organization changes the quality rating assigned to one or more
                 of the fund's securities, Pioneer will consider if any action is appropriate in light of the fund's investment
                 objectives and policies. An investor can still lose significant amounts when investing in investment grade
                 securities. These ratings are used as criteria for the selection of portfolio securities, in addition to Pioneer's
                 own assessment of the credit quality of potential investments.

------------------------------------------------------------------------------------------------------------------------------------
                 Mortgage-backed securities may be issued by private issuers, by government-sponsored entities such as the
                 Federal National Mortgage Association ("FNMA") or Federal Home Loan Mortgage Corporation ("FHLMC") or
                 by agencies of the U.S. government, such as the Government National Mortgage Association ("GNMA").
                 Mortgage-backed securities represent direct or indirect participation in, or are collateralized by and payable
                 from, mortgage loans secured by real property. The fund's investments in mortgage-related securities may
                 include mortgage derivatives and structured securities.

                 The fund may invest in collateralized mortgage obligations (CMOs). A CMO is a mortgage-backed bond that is
                 issued in multiple classes, each with a specified fixed or floating interest rate and a final scheduled
                 distribution date. The holder of an interest in a CMO is entitled to receive specified cash flows from a pool of

                  be entitled to payment before the cash flow from the pool is used to pay holders of other classes of the CMO
                  or, alternatively, the holder may be paid only to the extent that there is cash remaining after the cash flow has
                  been used to pay other classes. A subordinated interest may serve as a credit support for the senior securities
                  purchased by other investors.

                                                                          represent lower degrees of credit quality and are
                                                                          more sensitive to the rate of defaults in the pool of

                                                                          as credit default swaps, to create synthetic exposure

------------------------------------------------------------------------------------------------------------------------------------
Floating rate       The fund may invest in floating rate loans. Floating rate loans are provided by banks and other financial
loans               institutions to large corporate customers in connection with recapitalizations, acquisitions, and refinancings.
                    These loans are generally acquired as a participation interest in, or assignment of, loans originated by a
                    lender or other financial institution. These loans are rated below investment grade, but typically are secured
                    with specific collateral and have a senior position in the capital structure of the borrower. These loans
                    typically have rates of interest that are reset periodically by reference to a base lending rate, such as the
                    London Interbank Offered Rate (LIBOR), plus a premium.
------------------------------------------------------------------------------------------------------------------------------------
Subordinated        The fund may invest in securities that are subordinated or "junior" to more senior securities of the issuer. The
securities          investor in a subordinated security of an issuer is entitled to payment after other holders of debt in that
                    issuer.

                   purchase at a future date another U.S. agency
                   mortgage-backed security with the same interest
                   rate and maturity date, but generally backed by a
                   different pool of mortgages. The fund loses the right
                   to receive interest and principal payments in the
                   security it sold. However, the fund benefits from the
                   interest earned on investing the proceeds of the sale
                   and may receive a fee or a lower repurchase price.
------------------------------------------------------------------------------------------------------------------------------------
Derivatives        The fund may, but is not required to, use futures and options on securities, indices and currencies, forward
                   foreign currency exchange contracts, swaps and other derivatives. The fund also may enter into credit default
                   swaps, which can be used to acquire or to transfer the credit risk of a security or index of securities without
                   buying or selling the security or securities comprising the relevant index. A derivative is a security or
                   instrument whose value is determined by reference to the value or the change in value of one or more securities,
                   currencies, indices or other financial instruments. The fund may use derivatives for a variety of purposes,
                   including:

                   o   In an attempt to hedge against adverse changes in the market prices of securities, interest rates or
                       currency exchange rates
                   o   As a substitute for purchasing or selling securities
                   o   To attempt to increase the fund's return as a non-hedging strategy that may be considered speculative
                   o   To manage portfolio characteristics (for example, the duration or credit quality of the fund's portfolio)
                   o   As a cash flow management technique

                   The fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by
                   applicable law and regulations.
------------------------------------------------------------------------------------------------------------------------------------
Inverse floating   The fund may invest in inverse floating rate obligations (a type of derivative instrument). The interest rate on
rate obligations   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 issuer and with similar credit quality, redemption and maturity provisions. Inverse floating
                   rate obligations may be volatile and involve leverage risk.
------------------------------------------------------------------------------------------------------------------------------------
Repurchase         In a repurchase agreement, the fund purchases securities from a broker/dealer or a bank, called the
agreements         counterparty, upon the agreement of the counterparty to repurchase the securities from the fund at a later
                   date, and at a specified price, which is typically higher than the purchase price paid by the fund. The
                   securities purchased serve as the fund's collateral for the obligation of the counterparty to repurchase the
                   securities. If the counterparty does not repurchase the securities, the fund is entitled to sell the securities,
                   but the fund may not be able to sell them for the price at which they were purchased, thus causing a loss.
                   Additionally, if the counterparty becomes insolvent, there is some risk that the fund will not have a right to
                   the securities, or the immediate right to sell the securities.
------------------------------------------------------------------------------------------------------------------------------------
Reverse repurchase The fund may enter into reverse repurchase agreements pursuant to which the fund transfers securities to a
agreements and     counterparty in return for cash, and the fund agrees to repurchase the securities at a later date and for a
borrowing          higher price. Reverse repurchase agreements are treated as borrowings by the fund, are a form of leverage
                   and may make the value of an investment in the fund more volatile and increase the risks of investing in the
                   fund. The fund also may borrow money from banks or other lenders for temporary purposes. The fund may
                   borrow up to 33 1/3% of its total assets. Entering into reverse repurchase agreements and other borrowing
                   transactions may cause the fund to liquidate positions when it may not be advantageous to do so in order to
                   satisfy its obligations or meet segregation requirements.
------------------------------------------------------------------------------------------------------------------------------------
Cash management    Normally, the fund invests substantially all of its assets to meet its investment objectives. The fund may invest
and temporary      the remainder of its assets in securities with remaining maturities of less than one year or cash equivalents, or
investments        may hold cash. For temporary defensive purposes, including during periods of unusual cash flows, the fund
                   may depart from its principal investment strategies and invest part or all of its assets in these securities or
                   may hold cash. The fund may adopt a defensive strategy when the adviser believes securities in which the
                   fund normally invests have special or unusual risks or are less attractive due to adverse market, economic,
                   political or other conditions. During such periods, it may be more difficult for the fund to achieve its
                   investment objective.
------------------------------------------------------------------------------------------------------------------------------------
Short-term trading The fund usually does not trade for short-term profits. The fund will sell an investment, however, even if it has
                   only been held for a short time, if it no longer meets the fund's investment criteria. If the fund does a lot of
                   trading, it may incur additional operating expenses, which would reduce performance, and could cause
                   shareowners to incur a higher level of taxable income or capital gains.

Comparison of Principal Risks

      The following describe the common risks of investing in the Acquired Fund
      and the Acquiring Fund. For purposes of this section, "the fund" means the
      Acquired Fund, the Acquiring Fund, or, where applicable, an underlying
      fund.

      You could lose money on your investment in the fund. As with any mutual
      fund, there is no guarantee that the fund will achieve its objectives.

      Market risk. The values of securities held by the fund may go up or down,
      sometimes rapidly or unpredictably, due to general market conditions, such
      as real or perceived adverse economic, political, or regulatory
      conditions, inflation, changes in interest or currency rates, lack of
      liquidity in the bond markets or adverse investor sentiment. Changes in
      market conditions may not have the same impact on all types of securities.
      The values of securities may also fall due to specific conditions that
      affect a particular sector of the securities market or a particular
      issuer. In the past several years, financial markets, such as those in the
      United States, Europe, Asia and elsewhere, have experienced increased
      volatility, depressed valuations, decreased liquidity and heightened
      uncertainty. Governmental and non-governmental issuers have defaulted on,
      or been forced to restructure, their debts. These conditions may continue,
      recur, worsen or spread. The U.S. government and the Federal Reserve, as
      well as certain foreign governments and their central banks, have taken
      steps to support financial markets, including by keeping interest rates at
      historically low levels. This and other government intervention may not
      work as intended, particularly if the efforts are perceived by investors
      as being unlikely to achieve the desired results. The Federal Reserve
      recently has reduced its market support activities. Further reduction or
      withdrawal of Federal Reserve or other U.S. or non-U.S. governmental or
      central bank support, including interest rate increases, could negatively
      affect financial markets generally, increase market volatility and reduce
      the value and liquidity of securities in which the fund invests. Policy
      and legislative changes in the U.S. and in other countries are affecting
      many aspects of financial regulation, and may in some instances contribute
      to decreased liquidity and increased volatility in the financial markets.
      The impact of these changes on the markets, and the practical implications
      for market participants, may not be fully known for some time. Economies
      and financial markets throughout the world are becoming increasingly
      interconnected. As a result, whether or not the fund invests in securities
      of issuers located in or with significant exposure to countries
      experiencing economic and financial difficulties, the value and liquidity
      of the fund's investments may be negatively affected. The fund may
      experience a substantial or complete loss on any individual security or
      derivative position. Particularly during periods of declining or illiquid
      markets, the fund may experience periods of heavy redemptions that could
      cause the fund to liquidate its assets at inopportune times or at a loss
      or depressed value, and could cause the remaining shareholders in the fund
      to lose money. This redemption risk is greater to the extent that the fund
      has investors with large shareholdings, short investment horizons or
      unpredictable cash flow needs.

      Interest rate risk. The market prices of securities may fluctuate
      significantly when interest rates change. When interest rates rise, the
      value of fixed income securities and therefore the value of your
      investment in the fund, generally falls. Interest rates have been
      historically low, so the fund faces a heightened risk that interest rates
      may rise. A general rise in interest rates may cause investors to move out
      of fixed income securities on a large scale, which could adversely affect
      the price and liquidity of fixed income securities and could also result
      in increased redemptions from the fund. A change in interest rates will
      not have the same impact on all fixed income securities. Generally, the
      longer the maturity or duration of a fixed income security, the greater
      the impact of a rise in interest rates on the security's value. For
      example, if interest rates increase by 1%, the value of a fund's portfolio
      with a portfolio duration of ten years would be expected to decrease by
      10%, all other things being equal. Calculations of duration and maturity
      may be based on estimates and may not reliably predict a security's price
      sensitivity to changes in interest rates. Moreover, securities can change
      in value in response to other factors, such as credit risk. In addition,
      different interest rate measures (such as short- and long-term interest
      rates and U.S. and foreign interest rates), or interest rates on different
      types of securities or securities of different issuers, may not
      necessarily change in the same amount or in the same direction. When
      interest rates go down, the income received by the fund, and the fund's
      yield, may decline. Also, when interest rates decline, investments made by
      the fund may pay a lower interest rate, which would reduce the income
      received and distributed by the fund.

      Certain fixed income securities pay interest at variable or floating
      rates. Variable rate securities tend to reset at specified intervals,
      while floating rate securities may reset whenever there is a change in a
      specified index rate. In most cases, these reset provisions reduce the
      impact of changes in market interest rates on the value of the security.
      However, some securities do not track the underlying index directly, but
      reset based on formulas that may produce a leveraging effect; others may
      also provide for interest payments that vary inversely with market rates.
      The market prices of these securities may fluctuate significantly when
      interest rates change. Yield generated by the fund may decline due to a
      decrease in market interest rates.

      Credit risk. If an obligor (such as the issuer itself or a party offering
      credit enhancement) for a security held by the fund fails to pay,
      otherwise defaults, is perceived to be less creditworthy, becomes
      insolvent or files for bankruptcy, a security's credit rating is
      downgraded or the credit quality or value of an underlying asset declines,
      the value of your investment could decline. If the fund enters into
      financial contracts (such as certain derivatives, repurchase agreements,
      reverse repurchase agreements, and when-issued, delayed delivery and
      forward commitment transactions), the fund will be subject to the credit
      risk presented by the

                                       14


      counterparty. In addition, the fund may incur expenses in an effort
      to protect the fund's interests or to enforce its rights. Credit risk is
      broadly gauged by the credit ratings of the securities in which the fund
      invests. However, ratings are only the opinions of the companies issuing
      them and are not guarantees as to quality. Securities rated in the lowest
      category of investment grade (Baa/BBB) may possess certain speculative
      characteristics.

      Prepayment or call risk. Many fixed income securities give the issuer the
      option to prepay or call the security prior to its maturity date. Issuers
      often exercise this right when interest rates fall. Accordingly, if the
      fund holds a fixed income security that can be prepaid or called prior to
      its maturity date, it will not benefit fully from the increase in value
      that other fixed income securities generally experience when interest
      rates fall. Upon prepayment of the security, the fund also would be forced
      to reinvest the proceeds at then current yields, which would be lower than
      the yield of the security that was prepaid or called. In addition, if the
      fund purchases a fixed income security at a premium (at a price that
      exceeds its stated par or principal value), the fund may lose the amount
      of the premium paid in the event of prepayment.

      Extension risk. During periods of rising interest rates, the average life
      of certain types of securities may be extended because of slower than
      expected principal payments. This may lock in a below market interest
      rate, increase the security's duration and reduce the value of the
      security.

      To the extent the fund invests significantly in mortgage-related and
      asset-backed securities, its exposure to extension risks may be greater
      than if it invested in other fixed income securities.

      Liquidity risk. Liquidity risk exists when particular investments are
      impossible or difficult to purchase or sell. Although most of the fund's
      securities and other investments must be liquid at the time of investment,
      securities and other investments may become illiquid after purchase by the
      fund, particularly during periods of market turmoil. Markets may become
      illiquid when, for instance, there are few, if any, interested buyers and
      sellers or when dealers are unwilling to make a market for certain
      securities or when dealer market-making capacity is otherwise reduced, and
      this is more likely to occur as a result of the reduction of market
      support activity by the Federal Reserve. A lack of liquidity or other
      adverse credit market conditions may affect the fund's ability to sell the
      securities in which it invests or to find and purchase suitable
      investments. These illiquid investments may also be difficult to value. If
      the fund is forced to sell or unwind an illiquid investment to meet
      redemption requests or for other cash needs, the fund may suffer a loss.
      In addition, when there is illiquidity in the market for certain
      securities and other investments, the fund, due to limitations on
      investments in illiquid securities, may be unable to achieve its desired
      level of exposure to a certain sector. Liquidity risk may be magnified in
      a rising interest rate environment in which investor redemptions from
      fixed-income mutual funds may be higher than normal. If an auction fails
      for an auction rate security, there may be no secondary market for the
      security and the fund may be forced to hold the security until the
      security is refinanced by the issuer or a secondary market develops. To
      the extent the fund holds a material percentage of the outstanding debt
      securities of an issuer, this practice may impact adversely the liquidity
      and market value of those investments.

      Portfolio selection risk. The adviser's judgment about the quality,
      relative yield, relative value or market trends affecting a particular
      sector or region, market segment, security or about interest rates
      generally may prove to be incorrect.

      U.S. Treasury obligations risk. The market value of direct obligations of
      the U.S. Treasury may vary due to changes in interest rates. In addition,
      changes to the financial condition or credit rating of the U.S. government
      may cause the value of the fund's investments in obligations issued by the
      U.S. Treasury to decline.

      U.S. government agency obligations risk. The fund invests in obligations
      issued by agencies and instrumentalities of the U.S. government.
      Government-sponsored entities such as Federal National Mortgage
      Association ("FNMA"), Federal Home Loan Mortgage Corporation ("FHLMC") 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. Such debt and mortgage-backed securities
      are subject to the risk of default on the payment of interest and/or
      principal, similar to debt of private issuers. Although the U.S.
      government has provided financial support to FNMA and FHLMC in the past,
      there can be no assurance that it will support these or other
      government-sponsored entities in the future.

      Mortgage-related and asset-backed securities risk. The repayment of
      certain mortgage-backed and asset-backed securities depends primarily on
      the cash collections received from the issuer's underlying asset portfolio
      and, in certain cases, the issuer's ability to issue replacement
      securities. As a result, there could be losses to the fund in the event of
      credit or market value deterioration in the issuer's underlying portfolio,
      mismatches in the timing of the cash flows of the underlying asset
      interests and the repayment obligations of maturing securities, or the
      issuer's inability to issue new or replacement securities. Mortgage-backed
      securities tend to be more sensitive to changes in interest rate than
      other types of debt securities. These securities are also subject to
      prepayment and extension risks. Upon the occurrence of certain triggering
      events or defaults, the fund may become the holder of underlying assets at
      a time when those assets may be difficult to sell or may be sold only at a
      loss. In the event of a default, the value of the underlying collateral
      may be insufficient to pay certain expenses, such as litigation and
      foreclosure expenses, and inadequate to pay

                                       15


      any principal or unpaid interest. Privately issued mortgage-backed and
      asset-backed securities are not traded on an exchange and may have a
      limited market. Without an active trading market, these securities may be
      particularly difficult to value given the complexities in valuing the
      underlying collateral.

      Certain mortgage-backed and asset-backed securities may pay principal only
      at maturity or may represent only the right to receive payments of
      principal or interest on the underlying obligations, 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 obligations are prepaid.
      Interest only instruments could lose their entire value in a declining
      interest rate environment if the underlying obligations are prepaid.

      Unlike mortgage-related securities issued or guaranteed by the U.S.
      government or its agencies and instrumentalities, mortgage-related
      securities issued by private issuers do not have a government or
      government-sponsored entity guarantee (but may have other credit
      enhancement), and may, and frequently do, have less favorable collateral,
      credit risk or other characteristics. The fund may invest in other
      mortgage-related securities, including mortgage derivatives and structured
      securities. These securities typically are not secured by real property.
      Because these securities have embedded leverage features, small changes in
      interest or prepayment rates may cause large and sudden price movements.
      These securities also can become illiquid and difficult to value in
      volatile or declining markets.

      Mortgage-backed securities are particularly susceptible to prepayment and
      extension risks, because prepayments on the underlying mortgages tend to
      increase when interest rates fall and decrease when interest rates rise.
      Prepayments may also occur on a scheduled basis or due to foreclosure.
      When market interest rates increase, mortgage refinancings and prepayments
      slow, which lengthens the effective duration of these securities. As a
      result, the negative effect of the interest rate increase on the market
      value of mortgage-backed securities is usually more pronounced than it is
      for other types of fixed income securities, potentially increasing the
      volatility of the fund. Conversely, when market interest rates decline,
      while the value of mortgage-backed securities may increase, the rates of
      prepayment of the underlying mortgages tend to increase, which shortens
      the effective duration of these securities. Mortgage-backed securities are
      also subject to the risk that the underlying borrowers will be unable to
      meet their obligations.

      At times, some of the mortgage-backed securities in which the fund may
      invest will have higher than market interest rates and therefore will be
      purchased at a premium above their par value. Prepayments may cause losses
      on securities purchased at a premium.

      The value of mortgage-backed and asset-backed securities may be affected
      by changes in credit quality or value of the mortgage loans or other
      assets that support the securities. In addition, for mortgage-backed
      securities, when market conditions result in an increase in the default
      rates on the underlying mortgages and the foreclosure values of the
      underlying real estate are below the outstanding amount of the underlying
      mortgages, collection of the full amount of accrued interest and principal
      on these investments may be less likely.

      The fund may invest in CMOs. Principal prepayments on the underlying
      mortgage loans may cause a CMO to be retired substantially earlier than
      its stated maturity or final distribution date. If there are defaults on
      the underlying mortgage loans, the fund will be less likely to receive
      payments of principal and interest, and will be more likely to suffer a
      loss. This risk may be increased to the extent the underlying mortgages
      include sub-prime mortgages. As market conditions change, and particularly
      during periods of rapid or unanticipated changes in market interest rates,
      the attractiveness of a CMO class and the ability of the structure to
      provide the anticipated investment characteristics may be significantly
      reduced. Such changes can result in volatility in the market value, and in
      some instances reduced liquidity, of a CMO class.

      In response to the financial crisis that began in 2008, the Federal
      Reserve has attempted to keep mortgage rates low by acting as a buyer of
      mortgage-backed assets. This support has recently ended. As a result,
      mortgage rates may rise and prices of mortgage-backed securities may fall.
      To the extent the fund's assets are invested in mortgage-backed
      securities, returns to fund investors may decline.

      Asset-backed securities are structured like mortgage-backed securities and
      are subject to many of the same risks. The ability of an issuer of
      asset-backed securities to enforce its security interest in the underlying
      asset or to otherwise recover from the underlying obligor may be limited.
      Certain asset-backed securities present a heightened level of risk
      because, in the event of default, the liquidation value of the underlying
      assets may be inadequate to pay any unpaid principal or interest.

      Risks of investing in floating rate loans. Floating rate loans and similar
      investments may be illiquid or less liquid than other investments and
      difficult to value. The value of collateral, if any, securing a floating
      rate loan can decline or may be insufficient to meet the issuer's
      obligations or may be difficult to liquidate. In the event of a default,
      the fund may have difficulty collecting on any collateral and would not
      have the ability to collect on any collateral for an uncollateralized
      loan. Further, the fund's access to collateral, if any, may be limited by
      bankruptcy law. No active trading market may exist for many floating rate
      loans, and many loans are subject

                                       16


      to restrictions on resale. Market quotations for these securities may be
      volatile and/or subject to large spreads between bid and ask prices. Any
      secondary market may be subject to irregular trading activity and extended
      trade settlement periods. An economic downturn generally leads to a higher
      non-payment rate, and a loan may lose significant value before a default
      occurs. There is less readily available, reliable information about most
      floating rate loans than is the case for many other types of securities.
      Normally, Pioneer will seek to avoid receiving material, non-public
      information about the issuer of a loan either held by, or considered for
      investment by, the fund, and this decision could adversely affect the
      fund's investment performance. Loans may not be considered "securities,"
      and purchasers, such as the fund, therefore may not be entitled to rely on
      the anti-fraud protections of the federal securities laws.

      Risks of subordinated securities. A holder of securities that are
      subordinated or "junior" to more senior securities of an issuer is
      entitled to payment after holders of more senior securities of the issuer.
      Subordinated securities are more likely to suffer a credit loss than
      non-subordinated securities of the same issuer, any loss incurred by the
      subordinated securities is likely to be proportionately greater, and any
      recovery of interest or principal may take more time. If there is a
      default, bankruptcy or liquidation of the issuer, most subordinated
      securities are paid only if sufficient assets remain after payment of the
      issuer's non-subordinated securities. As a result, even a perceived
      decline in creditworthiness of the issuer is likely to have a greater
      impact on them.

      Municipal securities risk. The municipal bond market can be susceptible to
      unusual volatility, particularly for lower-rated and unrated securities.
      Liquidity can be reduced unpredictably in response to overall economic
      conditions or credit tightening. Municipal issuers may be adversely
      affected by rising health care costs, increasing unfunded pension
      liabilities and by the phasing out of federal programs providing financial
      support. Unfavorable conditions and developments relating to projects
      financed with municipal securities can result in lower revenues to issuers
      of municipal securities, potentially resulting in defaults. Issuers often
      depend on revenues from those projects to make principal and interest
      payments. The value of municipal securities can also be adversely affected
      by changes in the financial condition of one or more individual municipal
      issuers or insurers of municipal issuers, regulatory and political
      developments, tax law changes or other legislative actions, and by
      uncertainties and public perceptions concerning these and other factors.
      Municipal issuers may be more susceptible to downgrades or defaults during
      recessions or similar periods of economic stress. In recent periods, an
      increasing number of municipal issuers in the United States have defaulted
      on obligations and commenced insolvency proceedings. Financial
      difficulties of municipal issuers may continue or get worse. To the extent
      the fund invests significantly in a single state or in securities the
      payments on which are dependent upon a single project or source of
      revenues, or that relate to a sector or industry, the fund will be more
      susceptible to associated risks and developments.

      Risks of zero coupon bonds, payment in kind, deferred and contingent
      payment securities. Zero coupon bonds (which do not pay interest until
      maturity) and payment in kind securities (which pay interest in the form
      of additional securities) may be more speculative and may fluctuate more
      in value than securities that pay income periodically and in cash. These
      securities are more likely to respond to changes in interest rates than
      interest-bearing securities having similar maturities and credit quality.
      These securities are more sensitive to the credit quality of the
      underlying issuer. Payment in kind securities may be difficult to value
      because their continuing accruals require judgments about the
      collectability of the deferred payments and the value of any collateral.
      Deferred interest securities are obligations that generally provide for a
      period of delay before the regular payment of interest begins and are
      issued at a significant discount from face value.

      The interest rate on contingent payment securities is determined by the
      outcome of an event, such as the performance of a financial index. If the
      financial index does not increase by a prescribed amount, the fund may
      receive no interest.

      Unlike bonds that pay interest throughout the period to maturity, the fund
      generally will realize no cash until maturity and, if the issuer defaults,
      the fund may obtain no return at all on its investment. In addition,
      although the fund receives no periodic cash payments on such securities,
      the fund is deemed for tax purposes to receive income from such
      securities, which applicable tax rules require the fund to distribute to
      shareholders. Such distributions may be taxable when distributed to
      shareholders and, in addition, could reduce the fund's reserve position
      and require the fund to sell securities and incur a gain or loss at a time
      it may not otherwise want in order to provide the cash necessary for these
      distributions.

      Risks of investing in "when-issued", delayed delivery, to be announced and
      forward commitment transactions. The market value of these 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 or if the assets set aside
      to pay for these securities decline in value prior to the settlement date.
      Therefore, these transactions may have a leveraging effect on the fund,
      making the value of an investment in the fund more volatile and increasing
      the fund's overall investment exposure. There is also a risk that the
      security will not be issued or that the other party to the transaction
      will default on its obligation to purchase or sell the security, which may
      result in the fund missing the opportunity to obtain a favorable price or
      yield elsewhere.

      Derivatives risk. Using swaps, futures and other derivatives exposes the
      fund to special risks and costs and may result in losses to the fund, even
      when used for hedging purposes. Using derivatives can increase losses and
      reduce opportunities for gain when market prices, interest rates or
      currencies, or the derivative instruments themselves, behave in a way not
      anticipated by the fund, especially

                                       17


      in abnormal market conditions. Using derivatives can have a leveraging
      effect (which may increase investment losses) and increase the fund's
      volatility, which is the degree to which the fund's share price may
      fluctuate within a short time period. Certain derivatives have the
      potential for unlimited loss, regardless of the size of the fund's initial
      investment. If changes in a derivative's value do not correspond to
      changes in the value of the fund's other investments or do not correlate
      well with the underlying assets, rate or index, the fund may not fully
      benefit from, or could lose money on, or could experience unusually high
      expenses as a result of, the derivative position. The other parties to
      certain derivative transactions present the same types of credit risk as
      issuers of fixed income securities. Derivatives also tend to involve
      greater liquidity risk and they may be difficult to value. The fund may be
      unable to terminate or sell its derivative positions. In fact, many
      over-the-counter derivatives will not have liquidity beyond the
      counterparty to the instrument. Use of derivatives or similar instruments
      may have different tax consequences for the fund than an investment in the
      underlying security, and those differences may affect the amount, timing
      and character of income distributed to shareholders. The fund's use of
      derivatives may also increase the amount of taxes payable by shareholders.
      Risks associated with the use of derivatives are magnified to the extent
      that an increased portion of the fund's assets are committed to
      derivatives in general or are invested in just one or a few types of
      derivatives.

      Investments by the fund in structured securities, a type of derivative,
      raise certain tax, legal, regulatory and accounting issues that may not be
      presented by direct investments in securities. These issues could be
      resolved in a manner that could hurt the performance of the fund.

      Swap agreements and options to enter into swap agreements ("swaptions")
      tend to shift the fund's investment exposure from one type of investment
      to another. For example, the fund may enter into interest rate swaps,
      which involve the exchange of interest payments by the fund with another
      party, such as the exchange of floating rate payments for fixed interest
      payments with respect to a notional amount of principal. If an interest
      rate swap intended to be used as a hedge negates a favorable interest rate
      movement, the investment performance of the fund would be less than it
      would have been if the fund had not entered into the interest rate swap.

      The U.S. government and foreign governments are in the process of adopting
      and implementing regulations governing derivative markets, including
      mandatory clearing of certain derivatives, margin and reporting
      requirements. The ultimate impact of the regulations remains unclear.
      Additional regulation of derivatives may make derivatives more costly, may
      limit their availability or utility or otherwise adversely affect their
      performance, or may disrupt markets. The fund may be exposed to additional
      risks as a result of the additional regulations. The extent and impact of
      the regulations are not yet fully known and may not be for some time.

      The fund will be required to maintain its positions with a clearing
      organization through one or more clearing brokers. The clearing
      organization will require the fund to post margin and the broker may
      require the fund to post additional margin to secure the fund's
      obligations. The amount of margin required may change from time to time.
      In addition, cleared transactions may be more expensive to maintain than
      over-the-counter transactions and may require the fund to deposit larger
      amounts of margin. The fund may not be able to recover margin amounts if
      the broker has financial difficulties. Also, the broker may require the
      fund to terminate a derivatives position under certain circumstances. This
      may cause the fund to lose money. The fund's ability to use certain
      derivative instruments currently is limited by Commodity Futures Trading
      Commission rules.

      Risks of investing in inverse floating rate obligations. 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 issuer and
      with similar credit quality, redemption and maturity provisions. Inverse
      floating rate obligations may be volatile and involve leverage risk.

      Leveraging risk. The value of your investment may be more volatile and
      other risks tend to be compounded if the fund borrows or uses derivatives
      or other investments that have embedded leverage. Leverage generally
      magnifies the effect of any increase or decrease in the value of the
      fund's underlying assets and creates a risk of loss of value on a larger
      pool of assets than the fund would otherwise have, potentially resulting
      in the loss of all assets. Engaging in such transactions may cause the
      fund to liquidate positions when it may not be advantageous to do so to
      satisfy its obligations or meet segregation requirements.

      Repurchase agreement risk. In the event that the other party to a
      repurchase agreement defaults on its obligations, the fund may encounter
      delay and incur costs before being able to sell the security. Such a delay
      may involve loss of interest or a decline in price of the security. In
      addition, if the 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.

      Market segment risk. To the extent the 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 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 real estate investment trusts (REITs), may be sensitive
      to changes in interest rates and general economic activity and are
      generally subject to extensive government regulation.

                                       18



      Valuation risk. Many factors may influence the price at which the fund
      could sell any particular portfolio investment. The sales price may well
      differ -- higher or lower - from the fund's last valuation of the
      investment, and such differences could be significant, particularly for
      illiquid securities and securities that trade in thin markets and/or
      markets that experience extreme volatility. If market conditions make it
      difficult to value some investments, the fund may value these investments
      using more subjective methods. Investors who purchase or redeem fund
      shares on days when the fund is holding fair-valued securities may receive
      fewer or more shares or lower or higher redemption proceeds than they
      would have received if the fund had not fair-valued the security or had
      used a different valuation methodology. Fixed income securities are
      typically valued using fair value methodologies. The value of foreign
      securities, certain fixed income securities and currencies, as applicable,
      may be materially affected by events after the close of the market on
      which they are valued, but before the fund determines its net asset value.

      Cash management risk. The value of the investments held by the fund for
      cash management or temporary defensive purposes may be affected by market
      risks, changing interest rates and by changes in credit ratings of the
      investments. To the extent that the fund has any uninvested cash, the fund
      would be subject to credit risk with respect to the depository institution
      holding the cash. If the fund holds cash uninvested, the fund will not
      earn income on the cash and the fund's yield will go down. During such
      periods, it may be more difficult for the fund to achieve its investment
      objectives.

      Expense risk. Your actual costs of investing in the fund may be higher
      than the expenses shown in "Annual fund operating expenses" for a variety
      of reasons. For example, expense ratios may be higher than those shown if
      overall net assets decrease. Net assets are more likely to decrease and
      fund expense ratios are more likely to increase when markets are volatile.

In addition to the common risks of investing in the Acquired Fund and the
Acquiring Fund, the following are additional principal risks of investment in
the Acquiring Fund:

      Risks of instruments that allow for balloon payments or negative
      amortization payments. Certain debt instruments allow for balloon payments
      or negative amortization payments. Such instruments permit the borrower to
      avoid paying currently a portion of the interest accruing on the
      instrument. While these features make the debt instrument more affordable
      to the borrower in the near term, they increase the risk that the borrower
      will be unable to make the resulting higher payment or payments that
      become due at the maturity of the loan.

      High yield or "junk" bond risk. Debt securities that are below investment
      grade, called "junk bonds," are speculative, have a higher risk of default
      or are already in default, tend to be less liquid and are more difficult
      to value than higher grade securities and may involve major risk of
      exposure to adverse conditions and negative sentiments. These securities
      have a higher risk of issuer default because, among other reasons, issuers
      of junk bonds often have more debt in relation to total capitalization
      than issuers of investment grade securities. Junk bonds tend to be
      volatile and more susceptible to adverse events and negative sentiments.
      These risks are more pronounced for securities that are already in
      default. Changes in economic conditions or developments regarding the
      individual issuer are more likely to cause price volatility and weaken the
      capacity of such securities to make principal and interest payments than
      is the case for higher grade debt securities. The value of lower-quality
      debt securities often fluctuates in response to company, political, or
      economic developments and can decline significantly over short as well as
      long periods of time or during periods of general or regional economic
      difficulty. Junk bonds may also be less liquid than higher-rated
      securities, which means that the fund may have difficulty selling them at
      times, and it may have to apply a greater degree of judgment in
      establishing a price for purposes of valuing fund shares. Junk bonds
      generally are issued by less creditworthy issuers. In the event of an
      issuer's bankruptcy, claims of other creditors may have priority over the
      claims of junk bond holders, leaving few or no assets available to repay
      junk bond holders. The fund may incur expenses to the extent necessary to
      seek recovery upon default or to negotiate new terms with a defaulting
      issuer. Junk bonds frequently have redemption features that permit an
      issuer to repurchase the security from the fund before it matures. If the
      issuer redeems junk bonds, the fund may have to invest the proceeds in
      bonds with lower yields and may lose income.

      Risks of investing in insurance-linked securities. The return of principal
      and the payment of interest on "event-linked" bonds and other
      insurance-linked securities are contingent on the non-occurrence of a
      pre-defined "trigger" event, such as a hurricane or an earthquake of a
      specific magnitude or other event that leads to physical or economic loss.
      If a trigger event, as defined within the terms of an event-linked bond,
      involves losses or other metrics exceeding a specific magnitude in the
      geographic region and time period specified, the fund may lose a portion
      or all of its accrued interest and/or principal invested in the
      event-linked bond. In addition to the specified trigger events,
      event-linked bonds may expose the fund to other risks, including but not
      limited to issuer (credit) default, adverse regulatory or jurisdictional
      interpretations and adverse tax consequences. Event-linked bonds are also
      subject to the risk that the model used to calculate the probability of a
      trigger event was not accurate and underestimated the likelihood of a
      trigger event. Insurance-linked securities may provide for extensions of
      maturity in order to process and audit loss claims in those cases when a
      trigger event has, or possibly has, occurred. Upon the occurrence or
      possible occurrence of a trigger event, and until the completion of the
      processing and auditing of applicable loss claims, the fund's investment
      in an event-linked bond or other insurance-linked security may be priced
      using fair value methods. Lack of a liquid market may impose the risk of
      higher transaction costs and the possibility that the fund may be forced
      to liquidate positions when it would not be advantageous to do so. Certain


                                     19


      insurance-linked securities represent interests in baskets of underlying
      reinsurance contracts. The fund has limited transparency into the
      individual contracts underlying such securities and therefore must rely on
      the risk assessment and sound underwriting practices of the issuer.
      Certain insurance-linked securities may be difficult to value.

      Risks of non-U.S. investments. Investing in non-U.S. issuers, or in U.S.
      issuers that have significant exposure to foreign markets, 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, the adviser 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, or its ability to convert non-U.S.
            currencies to U.S. dollars

      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, regulatory and social developments may
            adversely affect the securities markets

      o     It may be difficult for the fund to pursue claims or enforce
            judgments against a foreign bank, depository or issuer of a
            security, or any of their agents, in the courts of a foreign country

      o     Withholding and other non-U.S. taxes may decrease the fund's return.
            The value of the fund's foreign investments also may be affected by
            U.S. tax considerations and restrictions in receiving investment
            proceeds from a foreign country

      o     Some markets in which the fund may invest are located in parts of
            the world that have historically been prone to natural disasters
            that could result in a significant adverse impact on the economies
            of those countries and investments made in those countries

      o     It is often more expensive for the fund to buy, sell and hold
            securities in certain foreign markets than in the United States

      o     A governmental entity may delay, or refuse or be unable to pay,
            interest or principal on its sovereign debt due to cash flow
            problems, insufficient foreign currency reserves, political
            considerations, the relative size of the governmental entity's debt
            position in relation to the economy or the failure to put in place
            economic reforms

      o     Investing in depositary receipts is subject to many of the same
            risks as investing directly in non-U.S. issuers. Depositary receipts
            may involve higher expenses and may trade at a discount (or premium)
            to the underlying security. In addition, depositary receipts may not
            pass through voting and other shareholder rights, and may be less
            liquid than the underlying securities listed on an exchange.

      o     A number of countries in the European Union (EU) have experienced,
            and may continue to experience, severe economic and financial
            difficulties. Additional EU member countries may also fall subject
            to such difficulties. These events could negatively affect the value
            and liquidity of the fund's investments in euro-denominated
            securities and derivative contracts, securities of issuers located
            in the EU or with significant exposure to EU issuers or countries

      o     If one or more stockholders of a supranational entity such as the
            World Bank fail to make necessary additional capital contributions,
            the entity may be unable to pay interest or repay principal on its
            debt securities


      Risks of convertible securities. Convertible securities generally offer
      lower interest or dividend yields than non-convertible securities of
      similar quality. As with all fixed income securities, the market values of
      convertible securities tend to decline as interest rates increase and,
      conversely, to increase as interest rates decline. However, when the
      market price of the common stock underlying a convertible security
      approaches or exceeds the conversion price, the convertible security tends
      to reflect the market price of the underlying common stock. As the market
      price of the underlying common stock declines, the convertible security
      tends to trade increasingly on a yield basis and thus may not decline in
      price to the same extent as the underlying common stock. Convertible
      securities rank senior to common stocks in an issuer's capital structure
      and consequently entail less risk than the issuer's common stock. The
      value of a synthetic convertible security will respond differently to
      market fluctuations than a traditional convertible security because a
      synthetic convertible security is composed of two or more separate
      securities or instruments, each with its own market value. If the value of
      the underlying common stock or the level of the index involved in the
      convertible component falls below the exercise price of the warrant or
      option, the warrant or option may lose all value.

      Preferred stocks risk. Preferred stocks may pay fixed or adjustable rates
      of return. Preferred stocks are subject to issuer-specific and market
      risks applicable generally to equity securities. In addition, a company's
      preferred stocks generally pay dividends only after the company makes
      required payments to holders of its bonds and other debt. Thus, the value
      of preferred stocks will usually react more strongly than bonds and other
      debt to actual or perceived changes in the company's financial condition
      or prospects.

                                       20



      The market value of preferred stocks generally decreases when interest
      rates rise. Preferred stocks of smaller companies may be more vulnerable
      to adverse developments than preferred stocks of larger companies.

      Credit default swap risk. Credit default swap contracts, a type of
      derivative instrument, involve heightened risks and may result in losses
      to the fund. Credit default swaps may in some cases be illiquid and
      difficult to value, and they increase credit risk since the fund has
      exposure to both the issuer of the referenced obligation and the
      counterparty to the credit default swap. If the fund buys a credit default
      swap, it will be subject to the risk that the credit default swap may
      expire worthless, as the credit default swap would only generate income in
      the event of a default on the underlying debt security or other specified
      event. As a buyer, the fund would also be subject to credit risk relating
      to the seller's payment of its obligations in the event of a default (or
      similar event). If the fund sells a credit default swap, it will be
      exposed to the credit risk of the issuer of the obligation to which the
      credit default swap relates. As a seller, the fund would also be subject
      to leverage risk, because it would be liable for the full notional amount
      of the swap in the event of default (or similar event). Swaps may be
      difficult to unwind or terminate. Certain index-based credit default swaps
      are structured in tranches, whereby junior tranches assume greater default
      risk than senior tranches. The absence of a central exchange or market for
      swap transactions may lead, in some instances, to difficulties in trading
      and valuation, especially in the event of market disruptions. New
      regulations require many kinds of swaps to be executed through a
      centralized exchange or regulated facility and be cleared through a
      regulated clearinghouse. Although this clearing mechanism is generally
      expected to reduce counterparty credit risk, it may disrupt or limit the
      swap market and may not result in swaps being easier to trade or value. As
      swaps become more standardized, the fund may not be able to enter into
      swaps that meet its investment needs. The fund also may not be able to
      find a clearinghouse willing to accept the swaps for clearing. In a
      cleared swap, a central clearing organization will be the counterparty to
      the transaction. The fund will assume the risk that the clearinghouse may
      be unable to perform its obligations. The new regulations may make using
      swaps more costly, may limit their availability, or may otherwise
      adversely affect their value or performance.

The following is an additional principal risk of the Acquired Fund; as noted
above, the Acquiring Fund is also permitted to invest in mortgage dollar roll
transactions:

      Mortgage dollar roll transactions risk. The benefits to the fund from
      mortgage dollar roll transactions depend upon the adviser's ability to
      forecast mortgage prepayment patterns on different mortgage pools. The
      fund may lose money if, during the period between the time it agrees to
      the forward purchase of the mortgage securities and the settlement date,
      these securities decline in value due to market conditions or prepayments
      on the underlying mortgages.

Comparison of Fees and Expenses

     Shareholders of both Pioneer 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 Pioneer Fund. The expenses
in the tables appearing below are based on (i) for the Acquired Fund, expenses
for the twelve-month period ended July 31, 2015, and (ii) for the Acquiring
Fund, expenses for the twelve-month period ended June 30, 2015. Future expenses
for all share classes may be greater or less. The tables also show the combined
fund's pro forma expenses assuming the Reorganization occurred on June 30,
2015.

(1)   Class A purchases of $500,000 or more that are not subject to an initial
      sales charge may be subject to a contingent deferred sales charge of 1%.
      See "Sales charges."

(2)   Pioneer has contractually agreed to limit ordinary operating expenses
      (ordinary operating expenses means all fund expenses other than
      extraordinary expenses, such as litigation, taxes, brokerage commissions
      and acquired fund fees and expenses) to the extent required to reduce fund
      expenses to 0.85% of the average daily net assets attributable to Class A
      shares. This expense limitation is in effect through November 1, 2017.
      There can be no assurance that Pioneer will extend the expense limitation
      beyond such time. While in effect, the arrangement may be terminated for a
      class only by agreement of the adviser and the Board of Trustees.


Examples:

The examples are intended to help you compare the cost of investing in each
fund with the cost of investing in other mutual funds. The examples assume that
you invest $10,000 in each fund for the time periods shown, and then, except as
indicated, redeem all of your shares at the end of those periods. The examples
also assume that (a) your investment has a 5% return each year and (b) each
fund's total annual operating expenses remain the same except for year one
(which considers the effect of the expense limitation). Pro forma expenses are
included assuming consummation of the Reorganization as of June 30, 2015. The
examples are for comparison purposes only and are not a representation of any
fund's actual expenses or returns, either past or future. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:

Comparison of the Funds' Past Performance

     The bar charts and tables below indicate the risks and volatility of an
investment in the funds by showing how the funds have performed in the past.
The bar charts show changes in the performance of each fund's Class A shares
from calendar year to calendar year. The tables shows average annual total
returns for each class of shares of each Fund over time and compare these
returns to the returns of a broad-based measure of market performance that has
characteristics relevant to the Fund's investment strategies. You can obtain
updated performance information by visiting https://us.pioneerinvestments.com/
performance or by calling 1-800-225-6292. A fund's past performance (before and
after taxes) does not necessarily indicate how it will perform in the future.
The bar charts do not reflect any sales charge you may pay when you buy fund
shares. If this amount was reflected, returns would be less than those shown.

(1)   During the period shown in the bar chart, the Acquired Fund's highest
      quarterly return was 4.41% for the quarter ended 12/31/2008, and the
      lowest quarterly return was -2.20% for the quarter ended 6/30/2013. For
      the period from January 1, 2015 through September 30, 2015, the Acquired
      Fund's return was 0.99%.

(2)   The Acquired Fund acquired the assets and liabilities of AmSouth
      Government Income Fund (the predecessor fund) on September 23, 2005. Prior
      to September 23, 2005, the Acquired Fund was advised by a different
      investment adviser. The performance of the Class A shares of the Acquired
      Fund includes the net asset value performance of the predecessor 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). The performance of Class Y shares of the Acquired Fund
      includes the net asset value performance of the predecessor fund's Class I
      shares prior to the reorganization, which has not been restated to reflect
      differences in expenses. If all the expenses of the Acquired Fund were
      reflected, the performance would be lower.

Reasons for the Reorganization

     The Board of Trustees of the Acquired Fund believes that the proposed
Reorganization will be advantageous to the shareholders of the Acquired Fund
for several reasons. The Trustees considered the following matters, among
others, in approving the proposal.

     First, the Board considered the similarities and differences in the funds'
investment objectives and principal investment strategies. The Board considered
that your fund and the Acquiring Fund have similar investment objectives to
provide current income. The Board considered that both funds invest primarily
in investment grade debt securities. The Board considered that the Acquiring
Fund may invest in a significantly broader range of debt securities than your
fund, noting that your fund invests at least 80% of its assets in U.S.
government securities, while the Acquiring Fund invests at least 80% of its
assets in investment grade debt securities, including corporate bonds and other
debt instruments in addition to U.S. government securities. The Board
considered that the Acquiring Fund also may invest up to 20% of its net assets
in debt securities rated below investment grade (known as "junk bonds").

     Second, the Board considered that your fund has not achieved a sufficient
size to allow for more efficient operations and is not likely to do so in the
future. The Board considered that the combined fund may be better positioned to
attract assets than your fund. The Board considered that the larger asset size
of the combined fund may allow it, relative to your fund, to reduce per share
expenses as fixed expenses will be shared over a larger asset base.

     Third, the Board considered that the expense ratio of each class of shares
of the combined fund is expected to be lower than the expense ratio of the
corresponding class of shares of your fund, both before and after any
applicable fee waivers or expense reimbursements.

     Fourth, the Board considered that the combined fund will pay a lower
management fee rate than the management fee rate paid by your fund.

     Fifth, the Board considered that the historical performance of the
Acquiring Fund was higher than the historical performance of your fund for the
three, five and ten-year periods ended October 2, 2015, based on data provided
by Morningstar, Inc. The Board noted that your fund's performance was higher
than the performance of the Acquiring Fund for the one-year period ended
October 2, 2015.

     Sixth, the Board considered the ability of the combined fund to utilize
certain tax capital-loss carryforwards in the future.

     Seventh, the Board considered that the Acquired Fund would bear
approximately 25% of the expenses incurred in connection with the
Reorganization, including expenses associated with the preparation, printing
and mailing of any shareholder communications (including this Information
Statement/Prospectus), any filings with the SEC and other governmental agencies
in connection with the Reorganization, audit fees and legal fees, and the
Acquiring Fund would likewise bear approximately 25% of these costs. The Board
considered that Pioneer would bear the remaining 50% of the expenses incurred
in connection with the Reorganization. In approving the allocation of
Reorganization costs, the Board considered information provided by Pioneer with
respect to the relative short-term economic benefits and costs to shareholders
anticipated to result from the Reorganization.

     Eighth, the Board considered that the Reorganization generally is not
expected to result in income, gain or loss being recognized for federal income
tax purposes by your fund, Pioneer Bond Fund or by the shareholders of either
fund.

     Ninth, the Board 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. The
consolidated portfolio management effort also might result in time and
personnel savings and the preparation of fewer reports and regulatory filings,
as well as prospectus disclosure, for one fund instead of two. The Board
believes that the Reorganization, in the long-term, could result in a decrease
in the combined fund's gross expenses.

     Tenth, the Board 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.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Pioneer Fund as
of December 18, 2015, and the pro forma combined capitalization of the combined
fund as if the Reorganization occurred on that date. 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 the Pioneer Funds
between December 18, 2015 and the Closing Date, changes in the amount of
undistributed net investment income and net realized capital gains of the
Pioneer Funds during that period resulting from income and distributions, and
changes in the accrued liabilities of the Pioneer Funds during the same period.

(1)   The pro forma data reflects adjustments to account for the combined
      expenses of the Reorganization borne by the Acquired Fund and the
      Acquiring Fund. The expenses of the Reorganization borne by the funds are
      estimated in the aggregate to be $62,500. Pioneer will bear the remaining
      expenses of the Reorganization.


     It is impossible to predict how many shares of the combined 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 combined fund shares
that will actually be received and distributed.

                    BOARDS' EVALUATION OF THE REORGANIZATION

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

                                       28


           OTHER IMPORTANT INFORMATION CONCERNING THE REORGANIZATION

                              Portfolio Securities

     After the closing of the Reorganization, management will analyze and
evaluate the portfolio securities of the combined fund. Consistent with the
combined fund's investment objective and policies, any restrictions imposed by
the Code and in the best interests of the shareholders of the combined fund
(including former shareholders of your fund), management will influence the
extent and duration to which the portfolio securities of your fund and the
Acquiring Fund will be maintained by the combined fund. It is possible that,
although it is not necessary to dispose of portfolio securities in order to
effect the Reorganization, the portfolio manager of the combined fund may
conclude that some of the holdings of the combined fund are not consistent with
the combined fund's long-term investment strategy, and, accordingly, there may
be dispositions of some of the portfolio securities of a combined fund
following the Reorganization. Subject to market conditions at the time of any
such disposition, the disposition of the portfolio securities by a combined
fund may result in a capital gain or loss. The actual tax consequences of any
disposition of portfolio securities will vary depending upon the specific
security(ies) being sold, other capital gains and losses that may be
recognized, and the combined fund's ability to use any available tax loss
carryforwards. The disposition of portfolio securities also may result in
significant brokerage expense to the combined fund.

                         Tax Capital Loss Carryforwards

     Federal income tax law permits a regulated investment company to carry
forward net capital losses that arose in tax years that began on or before
December 22, 2010 ("Pre-2011 Losses") for a period of up to eight taxable
years. Net capital losses that arise in tax years beginning after December 22,
2010 ("Post-2010 Losses") may generally be carried forward without limit, and
such carryforwards must be fully utilized before the regulated investment
company is permitted to utilize carryforwards of Pre-2011 Losses. Presently,
the net capital loss carryforwards of Pioneer Government Income Fund and
Pioneer Bond Fund from their prior taxable years can be summarized as follows:

     For the period ending on the Closing Date, each fund may have net realized
capital gains or losses and as of the Closing Date a fund may also have net
unrealized capital gains or losses.

     Your fund's Pre-2011 Losses, to the extent unused, will expire on the
earlier of July 31, 2016 and the date on which the Reorganization closes.

     The Reorganization may result in a number of additional limitations on the
combined fund's ability to use realized and unrealized losses of the combining
funds. The discussion below describes the limitations that may apply based on
the funds' tax attributes and relative net asset values as of October 31, 2015.
Since the Reorganization is not expected to close until March 11, 2016, the
net current-year realized capital losses and net unrealized capital gains and
the effect of the limitations described may change significantly between now
and the completion of the Reorganization. Further, the ability of your fund and
Pioneer Bond Fund to use capital losses to offset gains (even in the absence of
the Reorganization) depends on factors other than loss limitations, such as the
future realization of capital gains or losses.

                                       29


     First, in the tax year of the combined fund in which the Reorganization
occurs, the combined fund will be able to use carryforwards of your fund's
capital losses (including from your fund's short taxable year ending on the
Closing Date), subject to the limitations described in the following
paragraphs, to offset only a prorated portion of the combined fund's capital
gains for such tax year, based on the number of days remaining in the combined
fund's tax year after the Closing Date.

     Second, the Reorganization is expected to result in a limitation on the
combined fund's ability to use your fund's capital loss carryforwards in
subsequent tax years. This limitation, imposed by Section 382 of the Code, is
expected to apply because your fund has capital loss carryforwards and its
shareholders will own less than 50% of the combined fund immediately after the
Reorganization. The annual Section 382 limitation for periods following the
Reorganization generally will equal the product of the net asset value of your
Fund immediately prior to the Reorganization and the "long-term tax-exempt
rate," published by the Internal Revenue Service, in effect at the time of the
Reorganization (as of October 31, 2015, the annual limitation would be
$2,990,115).

     Third, the Reorganization may result in a limitation on the combined
fund's ability to use a portion of losses recognized by the combined fund in
the taxable year in which the Reorganization occurs, or, in certain cases, a
net unrealized loss inherent in the assets of Pioneer Bond Fund at the time of
the Reorganization, to offset gains realized after the Reorganization that are
attributable to unrealized capital gains of your fund as of the Closing Date.
That limitation will apply if your fund's unrealized capital gains as of the
Closing Date are at least $10,000,000 or at least 15% of the fair market value
of your fund's assets as of the Closing Date.

     Fourth, the Reorganization may result in a limitation on the combined
fund's ability to use capital loss carryforwards of your fund (including any
net loss from your fund's short taxable year ending on the date of the
Reorganization) to offset gains realized after the Reorganization that are
attributable to unrealized capital gains in Pioneer Bond Fund's assets
immediately prior to the Reorganization. This limitation will generally apply
if Pioneer Bond Fund's unrealized capital gains as of the date of the
Reorganization are at least $10,000,000 or at least 15% of the fair market
value of Pioneer Bond Fund's assets as of the Closing Date.

As of October 31, 2015, the funds had the following current-year realized
capital gains(losses) and net realized gains:



                                                                      
Fund                          Current-Year Realized Capital Gains(Losses)   Net Unrealized Gains
--------------------------------------------------------------------------------------------
Pioneer Government Income Fund                             $79,772               $3,548,104
--------------------------------------------------------------------------------------------
Pioneer Bond Fund                                       ($6,863,722)             $7,280,173


     Fifth, any capital loss carryforwards from prior years, any net
current-year capital losses, and, potentially, any unrealized capital losses
will benefit the shareholders of the combined fund, rather than only the
shareholders of the combining fund in which the loss originated.

TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION

The Reorganization

      o     The Reorganization is scheduled to occur as of the close of business
            on March 11, 2016 but may occur on such later date as the
            parties may agree to in writing.

      o     The Acquired Fund will transfer all of its assets to the Acquiring
            Fund. The Acquiring Fund will assume all of your fund's liabilities.
            The net asset value of both Pioneer Funds will be computed as of the
            close of regular trading on the New York Stock Exchange on the
            Closing Date.

      o     The Acquiring Fund will issue Class A, Class C and Class Y shares to
            the Acquired Fund in amounts equal to the aggregate net asset value
            of the Acquired Fund's Class A, Class C and Class Y shares,
            respectively.

      o     Shares of the Acquiring Fund will immediately be distributed to you
            in proportion to the relative net asset value of your holdings of
            shares of the applicable class or classes of the Acquired Fund on
            the Closing Date. As a result, the Acquired Fund's Class A
            shareholders will end up as Class A shareholders of the Acquiring
            Fund, and the Acquired Fund's Class C and Class Y shareholders will
            end up as Class C and Class Y shareholders, respectively, of the
            Acquiring Fund. The net asset value attributable to a class of
            shares of each fund will be determined using the Pioneer Funds'
            valuation policies and procedures. Each fund's valuation policies
            and procedures are identical.

      o     After the shares are issued, the Acquired Fund will be dissolved.

      o     No sales load, contingent deferred sales charge, commission,
            redemption fee or other transactional fee will be charged as a
            result of the Reorganization. After the Reorganization, any
            contingent deferred sales charge that applied to Class A (if
            applicable) or Class C shares of the Acquired Fund at the time of
            the Reorganization will continue to apply for the remainder of the
            applicable holding period at the time of the Reorganization. In
            calculating any applicable contingent deferred sales charge, the
            period during which you held your shares will be included in the
            holding period of the shares of the combined fund you receive as a
            result of the Reorganization.

      o     The Reorganization generally is not expected to result in income,
            gain or loss being recognized for federal income tax purposes by
            shareholders of either Pioneer Fund involved in the Reorganization,
            or by either your fund or Pioneer Bond Fund involved in the
            Reorganization, except as set forth below under the heading "Tax
            Status of the Reorganization." The Reorganization will not take
            place unless both funds involved in the Reorganization receive a tax
            opinion from Morgan, Lewis & Bockius LLP, counsel to the funds, as
            described below under the heading "Tax Status of the
            Reorganization".

Agreement and Plan of Reorganization

     The Agreement and Plan of Reorganization with respect to the
Reorganization is attached as Exhibit A to this Information
Statement/Prospectus. Material provisions of the Agreement and Plan of
Reorganization are described below, but are qualified in their 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 the
Acquired Fund's shares and will evidence ownership of shares of the combined
fund. The combined fund will not issue share certificates in the
Reorganization.

     Conditions to Closing the Reorganization. The obligation of the Acquired
Fund to consummate the Reorganization is subject to the satisfaction of certain
conditions, including the performance by the Acquiring 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 Acquiring Fund to consummate the Reorganization is
subject to the satisfaction of certain conditions, including the Acquired
Fund's performance of all of its obligations under the Agreement and Plan of
Reorganization, the receipt of certain documents and financial statements from
that fund and the receipt of all consents, orders and permits necessary to
consummate the Reorganization (see Agreement and Plan of Reorganization,
Section 7).

     The funds' obligations are subject to the receipt of a favorable opinion of
Morgan, Lewis & Bockius LLP as to the federal income tax consequences of the
Reorganization (see Agreement and Plan of Reorganization, Section 8.4).

     Termination of Agreement and Plan of Reorganization. The Board of Trustees
of either fund may terminate the Agreement and Plan of Reorganization at any
time before the Closing Date, if the Board believes that proceeding with the
Reorganization would no longer be in the best interests of shareholders of the
applicable fund.

                                       31


     Expenses of the Reorganization. Each fund will bear approximately 25% of
the expenses incurred in connection with the Reorganization, including expenses
associated with the preparation, printing and mailing of any shareholder
communications (including this Information Statement/Prospectus), any filings
with the SEC and other governmental agencies in connection with the
Reorganization, audit fees and legal fees ("Reorganization Costs"). Pioneer
will bear the remaining 50% of the Reorganization Costs.

                        TAX STATUS OF THE REORGANIZATION

     The Reorganization is conditioned upon the receipt by each fund of an
opinion from Morgan, Lewis & Bockius LLP, counsel to the Pioneer Funds,
substantially to the effect that, for federal income tax purposes:

      o     The transfer to the Acquiring Fund of all of your fund's assets in
            exchange solely for the issuance of the Acquiring Fund's shares to
            your fund and the assumption of all of your fund's liabilities by
            the Acquiring Fund, followed by the distribution of the Acquiring
            Fund's shares in complete liquidation of your fund, will constitute
            a "reorganization" within the meaning of Section 368(a) of the Code,
            and each of your fund and Pioneer Bond Fund will be a "party to a
            reorganization" within the meaning of Section 368(b) of the Code;

      o     No gain or loss will be recognized by your fund in the
            Reorganization upon (1) the transfer of all of its assets to the
            Acquiring Fund as described above or (2) the distribution by your
            fund of the Acquiring Fund's shares to your fund's shareholders in
            complete liquidation of your fund, except for (A) any gain or loss
            that may be recognized with respect to "section 1256 contracts" as
            defined in Section 1256(b) of the Code, (B) any gain that may be
            recognized on the transfer of stock in a "passive foreign investment
            company" as defined in Section 1297(a) of the Code, and (C) any
            other gain or loss that may be required to be recognized as a result
            of the closing of your fund's taxable year or upon the transfer of
            an asset regardless of whether such transfer would otherwise be a
            non-recognition transaction under the Code;

      o     The tax basis in the hands of Pioneer Bond Fund of the assets of
            your fund transferred in the Reorganization will be the same as the
            tax basis of the assets in the hands of your fund immediately before
            the transfer of the assets, increased by the amount of gain (or
            decreased by the amount of loss), if any, recognized by your fund on
            the transfer;

      o     The holding period of each asset of your fund in the hands of
            Pioneer Bond Fund, other than assets with respect to which gain or
            loss is required to be recognized in the Reorganization, will
            include the period during which that asset was held by your fund
            (except where investment activities of the Acquiring Fund will have
            the effect of reducing or eliminating the holding period with
            respect to an asset);

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

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

      o     The aggregate tax basis of Acquiring Fund shares you receive in the
            Reorganization will be the same as the aggregate tax basis of the
            shares of your fund you surrender in the exchange; and

      o     The holding period of Acquiring Fund shares you receive in the
            Reorganization will include the holding period of the shares of your
            fund that you surrender in the exchange, provided that you hold the
            shares of your fund as capital assets on the date of the exchange.

     In rendering such opinion, counsel shall rely upon, among other things,
certain facts, assumptions and representations of your fund and the Acquiring
Fund. The condition that each fund receives such an opinion may not be waived
by either 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.

     Immediately prior to the Reorganization, your fund will declare and pay a
dividend, which, together with all previous dividends, is intended to have the
effect of distributing to your fund's shareholders all of your fund's
investment company taxable income (computed without regard to the
dividends-paid deduction), all of its net tax-exempt income, and all of its net
capital gain (after deduction for any available capital loss carryover) for
taxable years ending on or prior to the Closing. The amount of such
distribution to the shareholders

                                       32


of your fund is estimated as of October 31, 2015 to be as set forth in the
table below. The amount set forth in the table below is an estimate based on
your fund's income and capital gains expected to be realized as if its taxable
year ended on the Closing Date. Amounts actually distributed to shareholders
immediately prior to the Reorganization may be higher or lower than the amounts
set forth in the table below.

     Such distributions will generally result in taxable income to you.

     The foregoing discussion is very general and does not take into account
any considerations that may 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.

                            your investment firm may receive a commission from the distributor of up to 4%, declining as the size
                            of your investment increases.
                        o   There is no contingent deferred sales charge, except in certain circumstances when no initial sales
                            charge is charged.

               BUYING, SELLING AND EXCHANGING SHARES OF THE FUNDS

     The table below provides information regarding how to buy, sell and
exchange shares of the Pioneer Funds. The policies disclosed below apply to
each Pioneer Fund.



               
------------------------------------------------------------------------------------------------------------------------------------
                                              Buying, Selling and Exchanging Shares
------------------------------------------------------------------------------------------------------------------------------------
Buying shares     You may buy fund shares from any financial intermediary that has a sales agreement or other arrangement with
                  the distributor.

                  You can buy shares at net asset value per share plus any applicable sales charge. The distributor may reject any
                  order until it has confirmed the order in writing and received payment. Normally, your financial intermediary will
                  send your purchase request to the fund's transfer agent. Consult your investment professional for more
                  information. Your investment firm receives a commission from the distributor, and may receive additional
                  compensation from Pioneer, for your purchase of fund shares.
------------------------------------------------------------------------------------------------------------------------------------
Minimum initial   Your initial investment must be at least $1,000 for Class A or Class C shares and at least $5 million for Class Y
investment        shares. Additional investments must be at least $100 for Class A shares and $500 for 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. The fund may
                  waive the initial or subsequent investment minimums. Minimum investment amounts may be waived for,
                  among other things, share purchases made through certain mutual fund programs (e.g., asset based fee
                  program accounts) sponsored by qualified intermediaries, such as broker-dealers and investment advisers, that
                  have entered into an agreement with Pioneer. There is no minimum additional investment amount for Class Y
                  shares.
------------------------------------------------------------------------------------------------------------------------------------
Maximum purchase  Purchases of each Pioneer Fund shares are limited to $499,999 for Class C shares. These limits are applied on
amounts           a per transaction basis. There is no maximum purchase for Class A or Class Y shares.
------------------------------------------------------------------------------------------------------------------------------------
Exchanging shares You may, under certain circumstances, exchange your shares for shares of the same class of another Pioneer
                  mutual fund.

                  Your exchange request must be for at least $1,000. The fund allows you to exchange your shares at net asset
                  value without charging you either an initial or contingent deferred sales charge at the time of the exchange.
                  Shares you acquire as part of an exchange will continue to be subject to any contingent deferred sales charge
                  that applies to the shares you originally purchased. When you ultimately sell your shares, the date of your
                  original purchase will determine your contingent deferred sales charge.
                  Before you request an exchange, consider each fund's investment objective and policies as described in the
                  fund's prospectus. You generally will have to pay income taxes on an exchange.
------------------------------------------------------------------------------------------------------------------------------------
Selling shares    Your shares will be sold at the share price (net asset value less any applicable sales charge) next calculated
                  after the fund or its authorized agent, such as a broker-dealer, receives your request in good order. If a
                  signature guarantee is required, you must submit your request in writing.

                  If the shares you are selling are subject to a deferred sales charge, it will be deducted from the sale proceeds.
                  The fund generally will send your sale proceeds by check, bank wire or electronic funds transfer. Normally you
                  will be paid within seven days. If you recently sent a check to purchase the shares being sold, the fund may
                  delay payment of the sale proceeds until your check has cleared. This may take up to 10 calendar days from the
                  purchase date.

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

                  You generally will have to pay income taxes on a sale.

                  If you must use a written request to exchange or sell your shares and your account is registered in the name of
                  a corporation or other fiduciary you must include the name of an authorized person and a certified copy of a
                  current corporate resolution, certificate of incumbency or similar legal document showing that the named
                  individual is authorized to act on behalf of the record owner.

------------------------------------------------------------------------------------------------------------------------------------
                Buying, Selling and Exchanging Shares
------------------------------------------------------------------------------------------------------------------------------------
Net asset       The fund's net asset value is the value of its securities plus any other assets minus its accrued operating
value           expenses and other liabilities. The fund calculates a net asset value for each class of shares every day the New
                York Stock Exchange is open as of the scheduled close of regular trading (normally 4:00 p.m. Eastern time). If
                the New York Stock Exchange closes at another time, the fund will calculate a net asset value for each class of
                shares as of the scheduled closing time. On days when the New York Stock Exchange is closed for trading,
                including certain holidays listed in the statement of additional information, a net asset value is not calculated.
                The fund's most recent net asset value is available on the fund's website, us.pioneerinvestments.com.

                The fund generally values debt securities and certain derivative instruments by using the prices supplied by
                independent third party pricing services. A pricing service may use market prices or quotations from one or
                more brokers or other sources, or may use a pricing matrix or other fair value methods or techniques to
                provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security
                on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed
                income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at
                the bid price obtained from an independent third party pricing service.

                Senior loans are valued at the mean between the last available bid and asked prices for one or more brokers or
                dealers as obtained from an independent third party pricing service. If no reliable prices are available from
                either the primary or an alternative pricing service, broker quotes will be solicited. Event linked bonds are
                valued at the bid price obtained from an independent third party pricing service. Other insurance-linked
                securities may be valued at the bid price obtained from an independent third party pricing service, or through a
                third party using a pricing matrix, insurance industry valuation models, or other fair value methods or
                techniques to provide an estimated value of the instrument.

                The fund generally values its equity securities and certain derivative instruments that are traded on an exchange
                using the last sale price on the principal exchange on which they are traded. Equity securities that are not
                traded on the date of valuation, or securities for which no last sale prices are available, are valued at the mean
                between the last bid and asked prices or, if both last bid and asked prices are not available, at the last quoted
                bid price.

                Last sale, bid and asked prices are provided by independent third party pricing services. In the case of equity
                securities not traded on an exchange, prices are typically determined by independent third party pricing
                services approved by the Board of Trustees using a variety of techniques and methods. The fund may use a fair
                value model developed by an independent pricing service to value non-U.S. equity securities.

                To the extent that the fund invests in shares of other mutual funds that are not traded on an exchange, such
                shares of other mutual funds are valued at their net asset values as provided by those funds. The prospectuses
                for those funds explain the circumstances under which those funds will use fair value pricing methods and the
                effects of using fair value pricing methods.

                The valuations of securities traded in non-U.S. markets and certain fixed income securities will generally be
                determined as of the earlier closing time of the markets on which they primarily trade. When the fund holds
                securities or other assets that are denominated in a foreign currency, the fund will normally use the currency
                exchange rates as of 3:00 p.m. (Eastern time). Non-U.S. markets are open for trading on weekends and other
                days when the fund does not price its shares. Therefore, the value of the fund's shares may change on days
                when you will not be able to purchase or redeem fund shares.

                When independent third party pricing services are unable to supply prices for an investment, or when prices or
                market quotations are considered by Pioneer to be unreliable, the value of that security may be determined
                using quotations from one or more broker-dealers. When such prices or quotations are not available, or when
                they are considered by Pioneer to be unreliable, the fund uses fair value methods to value its securities
                pursuant to procedures adopted by the Board of Trustees. The fund also may use fair value methods if it is
                determined that a significant event has occurred between the time at which a price is determined and the time
                at which the fund's net asset value is calculated. Because the fund may invest in securities rated below
                investment grade -- some of which may be thinly traded and for which prices may not be readily available or
                may be unreliable -- the fund may use fair value methods more frequently than funds that primarily invest in
                securities that are more widely traded. Valuing securities using fair value methods may cause the net asset
                value of the fund's shares to differ from the net asset value that would be calculated only using market prices.

                The prices used by the fund to value its securities may differ from the amounts that would be realized if these
                securities were sold and these differences may be significant, particularly for securities that trade in relatively
                thin markets and/or markets that experience extreme volatility.

                 ADDITIONAL INFORMATION ABOUT THE PIONEER FUNDS

Investment adviser

Pioneer Investment Management, Inc., as each fund's investment adviser (the
"Adviser"), selects the fund's investments and oversees the fund's operations.

Pioneer is an indirect, wholly owned subsidiary of UniCredit S.p.A.
("UniCredit"), 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 September
30, 2015, assets under management were approximately $243 billion worldwide,
including over $66 billion in assets under management by Pioneer (and its
U.S. affiliates).

On November 11, 2015, UniCredit announced that it signed a binding master
agreement with Banco Santander and affiliates of Warburg Pincus and General
Atlantic (the "Private Equity Firms") with respect to Pioneer Investments
("Pioneer") and Santander Asset Management ("SAM") (the "Transaction").

The Transaction, as previously announced by UniCredit, will establish a holding
company, with the name Pioneer Investments, to be owned by UniCredit (50%) and
the Private Equity Firms (50% between them). The holding company will control
Pioneer's U.S. operations, including the Adviser. The holding company also will
own 66.7% of Pioneer's and SAM's combined operations outside the U.S., while
Banco Santander will own directly the remaining 33.3% stake. The closing of the
Transaction is expected to happen in 2016, subject to certain regulatory and
other approvals.

Under the Investment Company Act of 1940, completion of the Transaction will
cause the Trust's investment advisory agreement with the Adviser to terminate.
In connection with the Transaction, the Trust's Board of Trustees will be asked
to approve a new investment advisory agreement for the Trust. If approved by
the Board, the Trust's new investment advisory agreement will be submitted to
the shareholders of the Trust for their approval.

Pioneer Investment Management, Inc.'s main office is at 60 State Street,
Boston, Massachusetts 02109.

The firm's U.S. mutual fund investment history includes creating one of the
first mutual funds in 1928.

The Adviser has received an order from the Securities and Exchange Commission
that permits Pioneer, subject to the approval of each Pioneer Fund's Board of
Trustees, to hire and terminate a subadviser that is not affiliated with
Pioneer (an "unaffiliated subadviser") or to materially modify an existing
subadvisory contract with an unaffiliated subadviser for the Pioneer Fund
without shareholder approval. Pioneer retains the ultimate responsibility to
oversee and recommend the hiring, termination and replacement of any
unaffiliated subadviser.

Portfolio managers

Day-to-day management of the Acquiring Fund's portfolio is the responsibility
of Kenneth J. Taubes. Mr. Taubes is supported by Charles Melchreit. Mr. Taubes
and Mr. Melchreit are supported by the fixed income team. Members of this team
manage other Pioneer funds investing primarily in fixed income securities. The
portfolio managers and the team also may draw upon the research and investment
management expertise of the global research teams, which provide fundamental
and quantitative research on companies and include members from one or more of
Pioneer's affiliates.

Mr. Taubes, Executive Vice President and Chief Investment Officer, U.S. of
Pioneer, is responsible for overseeing the U.S. and global fixed income teams.
He joined Pioneer as a senior vice president in September 1998 and has been an
investment professional since 1982. Mr. Taubes has served as portfolio manager
of the Acquiring Fund since 2004.

Mr. Melchreit, Senior Vice President, joined Pioneer in 2006, and has served as
portfolio manager of the Acquiring Fund since 2012.

Distributor

Pioneer Funds Distributor, Inc. is each Pioneer Fund's distributor. Each
Pioneer Fund compensates the distributor for its services. The distributor is
an affiliate of Pioneer.

Disclosure of portfolio holdings

Each Pioneer Fund's policies and procedures with respect to the disclosure of
its portfolio securities are described in the fund's statement of additional
information.

                                       37


Distribution and service arrangements

Distribution Plan

Each Pioneer Fund has adopted a distribution plan for its Class A and Class C
shares in accordance with Rule 12b-1 under the 1940 Act. Under each plan, a
Pioneer Fund pays distribution and service fees to the distributor. Because
these fees are an ongoing expense of a Pioneer 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

Your financial intermediary may receive compensation from a Pioneer Fund,
Pioneer and its affiliates for the sale of a Pioneer Fund's shares and related
services. Compensation may include sales commissions and distribution and
service (Rule 12b-1) fees, as well as compensation for administrative services
and transaction processing.

Pioneer and its affiliates may make additional payments to your financial
intermediary. These payments 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 Pioneer 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, which may include
profits derived from services provided to a Pioneer Fund, or from the retention
of a portion of sales charges or distribution and service fees. Pioneer may
base these payments on a variety of criteria, including the amount of sales or
assets of the Pioneer funds 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 may 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 (in addition to amounts
that may be paid by the fund) 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 Pioneer 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. The
intermediary may earn a profit on these payments if the amount of the payment
to the intermediary exceeds 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 in 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 Pioneer funds, such
as providing omnibus account services or effecting portfolio transactions for
the Pioneer funds. If your intermediary provides these 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 Pioneer funds.

Initial Sales Charge (Class A Shares Only)

You pay the offering price (the net asset value per share plus any initial
sales charge) when you buy Class A shares unless you qualify to purchase shares
at net asset value. You pay a lower sales charge as the size of your investment
increases. You do not pay a sales charge when you reinvest dividends or capital
gain distributions paid by a Pioneer Fund.

The dollar amount of the sales charge is the difference between the offering
price of the shares purchased (based on the applicable sales charge in the
table) and the net asset value of those shares. Since the offering price is
calculated to two decimal places using standard rounding methodology, the
dollar amount of the sales charge as a percentage of the offering price and of
the net amount invested for any particular purchase of Pioneer Fund shares may
be higher or lower due to rounding.

Reduced sales charges

You may qualify for a reduced Class A sales charge if you own or are purchasing
shares of Pioneer mutual funds. The investment levels required to obtain a
reduced sales charge are commonly referred to as "breakpoints." Pioneer offers
two principal means of taking advantage of breakpoints in sales charges for
aggregate purchases of Class A shares of the Pioneer funds over time if:

      o     The amount of shares you own of the Pioneer funds plus the amount
            you are investing now is at least $100,000 (Rights of accumulation)

      o     You plan to invest at least $100,000 over the next 13 months (Letter
            of intent)


Rights of accumulation

If you qualify for rights of accumulation, your sales charge will be based on
the combined value (at the current offering price) of all your Pioneer mutual
fund shares, the shares of your spouse and the shares of any children under the
age of 21.

Letter of intent

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

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

      o     If you include in your letter of intent the value (at the current
            offering price) of all of your Class A shares of a Pioneer Fund and
            Class A or Class C shares of all other Pioneer mutual fund shares
            held of record in the amount used to determine the applicable sales
            charge for Pioneer Fund shares you plan to buy


Completing a letter of intent does not obligate you to purchase additional
shares, but if you do not buy enough shares to qualify for the projected level
of sales charges by the end of the 13-month period (or when you sell your
shares, if earlier), the distributor will recalculate your sales charge. You
must pay the additional sales charge within 20 days after you are notified of
the recalculation or it will be deducted from your account (or your sale
proceeds). Any share class for which no sales charge is paid cannot be included
under the letter of intent. For more information regarding letters of intent,
please contact your investment professional or obtain and read the statement of
additional information.

Qualifying for a reduced Class A sales charge

In calculating your total account value in order to determine whether you have
met sales charge breakpoints, you can include your Pioneer mutual fund shares,
those of your spouse and the shares of any children under the age of 21.
Pioneer will use each fund's current offering price to calculate your total
account value. Certain trustees and fiduciaries may also qualify for a reduced
sales charge.

To receive a reduced sales charge, you or your investment professional must, at
the time of purchase, notify the distributor of your eligibility. In order to
verify your eligibility for a discount, you may need to provide your investment
professional or the fund with information or records, such as account numbers
or statements, regarding shares of the fund or other Pioneer mutual funds held
in all accounts by you, your spouse or children under the age of 21 with that
investment professional or with any other financial intermediary. Eligible
accounts may include joint accounts, retirement plan accounts, such as IRA and
401k accounts, and custodial accounts, such as ESA, UGMA and UTMA accounts.

                                       39


It is your responsibility to confirm that your investment professional has
notified the distributor of your eligibility for a reduced sales charge at the
time of sale. If you or your investment professional do not notify the
distributor of your eligibility, you will risk losing the benefits of a reduced
sales charge.

For this purpose, Pioneer mutual funds include any fund for which the
distributor is principal underwriter and, at the distributor's discretion, may
include funds organized outside the U.S. and managed by Pioneer or an
affiliate.

You can locate information regarding the reduction or waiver of sales charges,
in a clear and prominent format and free of charge, on Pioneer's website at
www.pioneerinvestments.com. The website includes hyperlinks that facilitate
access to this information.

Class A purchases at net asset value

You may purchase Class A shares at net asset value (without a sales charge) as
follows. If you believe you qualify for any of the Class A sales charge waivers
discussed below, contact your investment professional or the distributor. You
are required to provide written confirmation of your eligibility. You may not
resell these shares except to or on behalf of the fund.

Class A purchases at net asset value are available to:

      o     Current or former trustees and officers of the fund;

      o     Partners and employees of legal counsel to the fund (at the time of
            initial share purchase);

      o     Directors, officers, employees or sales representatives of Pioneer
            and its affiliates (at the time of initial share purchase);

      o     Directors, officers, employees or sales representatives of any
            subadviser or a predecessor adviser (or their affiliates) to any
            investment company for which Pioneer serves as investment adviser
            (at the time of initial share purchase);

      o     Officers, partners, employees or registered representatives of
            broker-dealers (at the time of initial share purchase) which have
            entered into sales agreements with the distributor;

      o     Employees of Regions Financial Corporation and its affiliates (at
            the time of initial share purchase);

      o     Members of the immediate families of any of the persons above;

      o     Any trust, custodian, pension, profit sharing or other benefit plan
            of the foregoing persons;

      o     Insurance company separate accounts;

      o     Certain wrap accounts for the benefit of clients of investment
            professionals or other financial intermediaries adhering to
            standards established by the distributor;

      o     Other funds and accounts for which Pioneer or any of its affiliates
            serves as investment adviser or manager;

      o     Investors in connection with certain reorganization, liquidation or
            acquisition transactions involving other investment companies or
            personal holding companies;

      o     Certain unit investment trusts;

      o     Group employer-sponsored retirement plans with at least $500,000 in
            total plan assets. Waivers for group employer-sponsored retirement
            plans do not apply to traditional IRAs, Roth IRAs, SEPs, SARSEPs,
            SIMPLE IRAs, KEOGHs, individual 401(k) or individual 403(b) plans,
            or to brokerage relationships in which sales charges are customarily
            imposed;

      o     Group employer-sponsored retirement plans with accounts established
            with Pioneer on or before March 31, 2004 with 100 or more eligible
            employees or at least $500,000 in total plan assets;

      o     Participants in an employer-sponsored 403(b) plan or
            employer-sponsored 457 plan if (i) your employer has made special
            arrangements for your plan to operate as a group through a single
            broker, dealer or financial intermediary and (ii) all participants
            in the plan who purchase shares of a Pioneer mutual fund do so
            through a single broker, dealer or other financial intermediary
            designated by your employer;

      o     Investors purchasing shares pursuant to the reinstatement privilege
            applicable to Class A shares; and

      o     Shareholders of record (i.e., shareholders whose shares are not held
            in the name of a broker or an omnibus account) on the date of the
            reorganization of a predecessor Safeco fund into a corresponding
            Pioneer fund, shareholders who owned shares in the name of an
            omnibus account provider on that date that agrees with the fund to
            distinguish beneficial holders in the same manner, and retirement
            plans with assets invested in the predecessor Safeco fund on that
            date.


                                       40


In addition, Class A shares may be purchased at net asset value through certain
mutual fund programs sponsored by qualified intermediaries, such as
broker-dealers and investment advisers. In each case, the intermediary has
entered into an agreement with Pioneer to include the Pioneer funds in their
program without the imposition of a sales charge. The intermediary provides
investors participating in the program with additional services, including
advisory, asset allocation, recordkeeping or other services. You should ask
your investment firm if it offers and you are eligible to participate in such a
mutual fund program and whether participation in the program is consistent with
your investment goals. The intermediaries sponsoring or participating in these
mutual fund programs also may offer their clients other classes of shares of
the funds and investors may receive different levels of services or pay
different fees depending upon the class of shares included in the program.
Investors should consider carefully any separate transaction and other fees
charged by these programs in connection with investing in each available share
class before selecting a share class. Such mutual fund programs include certain
self-directed brokerage services accounts held through qualified intermediaries
that may or may not charge participating investors transaction fees.

Contingent deferred sales charges (CDSCs)

Class A shares

Purchases of Class A shares of $500,000 or more, or by participants in a group
plan which were not subject to an initial sales charge, may be subject to a
contingent deferred sales charge upon redemption. A contingent deferred sales
charge is payable to the distributor in the event of a share redemption within
12 months following the share purchase at the rate of 1% of the lesser of the
value of the shares redeemed (exclusive of reinvested dividend and capital gain
distributions) or the total cost of such shares. However, the contingent
deferred sales charge is waived for redemptions of Class A shares purchased by
an employer-sponsored retirement plan that has at least $500,000 in total plan
assets (or that has 1,000 or more eligible employees for plans with accounts
established with Pioneer on or before March 31, 2004).

Class C shares

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

Paying the contingent deferred sales charge (CDSC)

Several rules apply for calculating CDSCs so that you pay the lowest possible
CDSC.

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

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

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

      o     You may qualify for a waiver of the CDSC normally charged. See
            "Waiver or reduction of contingent deferred sales charges"

Waiver or reduction of contingent deferred sales charges

It is your responsibility to confirm that your investment professional has
notified the distributor of your eligibility for a reduced sales charge at the
time of sale. If you or your investment professional do not notify the
distributor of your eligibility, you will risk losing the benefits of a reduced
sales charge.

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

      o     The distribution results from the death of all registered account
            owners or a participant in an employer-sponsored plan. For UGMAs,
            UTMAs and trust accounts, the waiver applies only upon the death of
            all beneficial owners;

      o     You become disabled (within the meaning of Section 72 of the
            Internal Revenue Code) after the purchase of the shares being sold.
            For UGMAs, UTMAs and trust accounts, the waiver only applies upon
            the disability of all beneficial owners;

      o     The distribution is made in connection with limited automatic
            redemptions as described in "Systematic withdrawal plans" (limited
            in any year to 10% of the value of the account in the fund at the
            time the withdrawal plan is established);

      o     The distribution is from any type of IRA, 403(b) or
            employer-sponsored plan described under Section 401(a) or 457 of the
            Internal Revenue Code and, in connection with the distribution, one
            of the following applies:


                                       41



          --It is part of a series of substantially equal periodic payments made
            over the life expectancy of the participant or the joint life
            expectancy of the participant and his or her beneficiary (limited in
            any year to 10% of the value of the participant's account at the
            time the distribution amount is established);

          --It is a required minimum distribution due to the attainment of age
            70 1/2, in which case the distribution amount may exceed 10% (based
            solely on total plan assets held in Pioneer mutual funds);

          --It is rolled over to or reinvested in another Pioneer mutual fund in
            the same class of shares, which will be subject to the CDSC of the
            shares originally held; or

          --It is in the form of a loan to a participant in a plan that permits
            loans (each repayment applied to the purchase of shares will be
            subject to a CDSC as though a new purchase);

      o     The distribution is to a participant in an employer-sponsored
            retirement plan described under Section 401(a) of the Internal
            Revenue Code or to a participant in an employer-sponsored 403(b)
            plan or employer-sponsored 457 plan if (i) your employer has made
            special arrangements for your plan to operate as a group through a
            single broker, dealer or financial intermediary and (ii) all
            participants in the plan who purchase shares of a Pioneer mutual
            fund do so through a single broker, dealer or other financial
            intermediary designated by your employer and is or is in connection
            with:

          --A return of excess employee deferrals or contributions;

          --A qualifying hardship distribution as described in the Internal
            Revenue Code;

          --Due to retirement or termination of employment;

          --From a qualified defined contribution plan and represents a
            participant's directed transfer, provided that this privilege has
            been preauthorized through a prior agreement with the distributor
            regarding participant directed transfers;

      o     The distribution is made pursuant to the fund's right to liquidate
            or involuntarily redeem shares in a shareholder's account;

      o     The distribution is made to pay an account's advisory or custodial
            fees; or

      o     The distributor does not pay the selling broker a commission
            normally paid at the time of the sale.

Buying, exchanging and selling shares

Opening your account

You may open an account by completing an account application and sending it to
the transfer agent by mail or by fax. Please call the transfer agent to obtain
an account application. Certain types of accounts, such as retirement accounts,
have separate applications.

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 Funds
P.O. Box 55014
Boston, Massachusetts 02205-5014
Telephone 1-800-225-6292

Please note that there may be a delay in receipt by the transfer agent of
applications submitted by regular mail to a post office address.

Each Pioneer Fund is generally available for purchase in the United States,
Puerto Rico, Guam, American Samoa and the U.S. Virgin Islands. Except to the
extent otherwise permitted by the Pioneer Funds' distributor, the Pioneer Funds
will only accept accounts from U.S. citizens with a U.S. address (including an
APO or FPO address) or resident aliens with a U.S. address (including an APO or
FPO address) and a U.S. tax payer identification number.

Identity verification

To help the government fight the funding of terrorism and money laundering
activities, federal law requires all financial institutions to obtain, verify
and record information that identifies each person who opens an account. When
you open an account, you will need to supply your name, address, date of birth,
and other information that will allow the fund to identify you.

                                       42


A Pioneer Fund may close your account if we cannot adequately verify your
identity. The redemption price will be the net asset value on the date of
redemption.

Investing through financial intermediaries and retirement plans

If you invest in a Pioneer Fund through your financial intermediary or through
a retirement plan, the options and services available to you may be different
from those discussed in this Information Statement / Prospectus. Shareholders
investing through financial intermediaries, programs sponsored by financial
intermediaries and retirement plans may only purchase funds and classes of
shares that are available. When you invest through an account that is not in
your name, you generally may buy and sell shares and complete other
transactions only through the account. Ask your investment professional or
financial intermediary for more information.

Additional conditions may apply to your investment in a Pioneer Fund, and the
investment professional or intermediary may charge you a transaction-based,
administrative 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.

Share prices for transactions

If you place an order to purchase, exchange or sell shares with the transfer
agent or an authorized agent by the close of regular trading on the New York
Stock Exchange (usually 4:00 p.m. Eastern time), the share price for your
transaction will be based on the net asset value determined as of the close of
regular trading on the New York Stock Exchange on that day (plus or minus any
applicable sales charges). If your order is placed with the transfer agent or
an authorized agent after the close of regular trading on the New York Stock
Exchange, or your order is not in good order, the share price will be based on
the net asset value next determined after your order is received in good order
by the fund or authorized agent. The authorized agent is responsible for
transmitting your order to the fund in a timely manner.

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 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's record
              owner(s)

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

Transaction limitations

Your transactions are subject to certain limitations, including the limitation
on the purchase of a Pioneer Fund's shares within 30 calendar days of a
redemption. See "Excessive trading."

Buying, exchanging and selling shares

Buying

You may buy a Pioneer Fund's shares from any financial intermediary that has a
sales agreement or other arrangement with the distributor.

You can buy shares at net asset value per share plus any applicable sales
charge. The distributor may reject any order until it has confirmed the order
in writing and received payment. Normally, your financial intermediary will
send your purchase request to the Pioneer Fund's transfer agent. Consult your
investment professional for more information. Your investment firm receives a
commission from the distributor, and may receive additional compensation from
Pioneer, for your purchase of shares of a Pioneer Fund.

                                       43


Minimum investment amounts

Class A and Class C shares

Your initial investment must be at least $1,000. Additional investments must be
at least $100 for Class A shares and $500 for 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. A Pioneer Fund may waive the
initial or subsequent investment minimums. Minimum investment amounts may be
waived for, among other things, share purchases made through certain mutual
fund programs (e.g., asset based fee program accounts) sponsored by qualified
intermediaries, such as broker-dealers and investment advisers, that have
entered into an agreement with Pioneer.

Class Y shares

Your initial investment in Class Y shares must be at least $5 million. This
amount may be invested in one or more of the Pioneer mutual funds that
currently offer Class Y shares. There is no minimum additional investment
amount. A Pioneer Fund may waive the initial investment amount.

Waiver of the minimum investment amount for Class Y

The fund will accept an initial investment of less than $5 million if:

      (a)   The investment is made by a trust company or bank trust department
            which is initially investing at least $1 million in any of the
            Pioneer mutual funds and, at the time of the purchase, such assets
            are held in a fiduciary, advisory, custodial or similar capacity
            over which the trust company or bank trust department has full or
            shared investment discretion; or

      (b)   The investment is at least $1 million in any of the Pioneer mutual
            funds and the purchaser is an insurance company separate account; or

      (c)   The account is not represented by a broker-dealer and the investment
            is made by (1) an ERISA-qualified retirement plan that meets the
            requirements of Section 401 of the Internal Revenue Code, (2) an
            employer-sponsored retirement plan that meets the requirements of
            Sections 403 or 457 of the Internal Revenue Code, (3) a private
            foundation that meets the requirements of Section 501(c)(3) of the
            Internal Revenue Code or (4) an endowment or other organization that
            meets the requirements of Section 509(a)(1) of the Internal Revenue
            Code; or

      (d)   The investment is made by an employer-sponsored retirement plan
            established for the benefit of (1) employees of Pioneer or its
            affiliates, or (2) employees or the affiliates of broker-dealers who
            have a Class Y shares sales agreement with the distributor; or

      (e)   The investment is made through certain mutual fund programs
            sponsored by qualified intermediaries, such as broker-dealers and
            investment advisers. In each case, the intermediary has entered into
            an agreement with Pioneer to include Class Y shares of the Pioneer
            mutual funds in their program. The intermediary provides investors
            participating in the program with additional services, including
            advisory, asset allocation, recordkeeping or other services. You
            should ask your investment firm if it offers and you are eligible to
            participate in such a mutual fund program and whether participation
            in the program is consistent with your investment goals. The
            intermediaries sponsoring or participating in these mutual fund
            programs may also offer their clients other classes of shares of the
            funds and investors may receive different levels of services or pay
            different fees depending upon the class of shares included in the
            program. Investors should consider carefully any separate
            transaction and other fees charged by these programs in connection
            with investing in each available share class before selecting a
            share class; or

      (f)   The investment is made by another Pioneer fund.

The fund reserves the right to waive the initial investment minimum in other
circumstances.

Maximum purchase amounts

Purchases of shares of a Pioneer Fund are limited to $499,999 for Class C
shares. This limit is applied on a per transaction basis. Class A and Class Y
shares are not subject to a maximum purchase amount.

Retirement plan accounts

You can purchase shares of a Pioneer Fund through tax-deferred retirement plans
for individuals, businesses and tax-exempt organizations.

                                       44


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

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

How to buy shares

Through your investment firm

Normally, your investment firm will send your purchase request to the Pioneer
Funds' distributor and/or transfer agent. Consult your investment professional
for more information. Your investment firm receives a commission from the
distributor, and may receive additional compensation from Pioneer, for your
purchase of shares of a Pioneer Fund.

By phone or online

You can use the telephone or online purchase privilege if you have an existing
non-retirement account. Certain IRAs can use the telephone purchase privilege.
If your account is eligible, you can purchase additional fund shares by phone
or online if:

      o     You established your bank account of record at least 30 days ago

      o     Your bank information has not changed for at least 30 days

      o     You are not purchasing more than $100,000 worth of shares per
            account per day

      o     You can provide the proper account identification information

When you request a telephone or online purchase, the transfer agent will
electronically debit the amount of the purchase from your bank account of
record. The transfer agent will purchase shares of the Pioneer Fund for the
amount of the debit at the offering price determined after the transfer agent
receives your telephone or online purchase instruction and good funds. It
usually takes three business days for the transfer agent to receive
notification from your bank that good funds are available in the amount of your
investment.

In writing, by mail

You can purchase shares of a Pioneer Fund for an existing fund account by
mailing a check to the fund. Make your check payable to the Pioneer Fund.
Neither initial nor subsequent investments should be made by third party check,
travelers check, or credit card check. Your check must be in U.S. dollars and
drawn on a U.S. bank. Include in your purchase request the Pioneer Fund's name,
the account number and the name or names in the account registration. Please
note that there may be a delay in receipt by the fund's transfer agent of
purchase orders submitted by regular mail to a post office address.

By wire (Class Y shares only)

If you have an existing (Class Y shares only) account, you may wire funds to
purchase shares. Note, however, that:

      o     State Street Bank must receive your wire no later than 11:00 a.m.
            Eastern time on the business day after the Pioneer Fund receives
            your request to purchase shares

      o     If State Street Bank does not receive your wire by 11:00 a.m.
            Eastern time on the next business day, your transaction will be
            canceled at your expense and risk

      o     Wire transfers normally take two or more hours to complete and a fee
            may be charged by the sending bank

      o     Wire transfers may be restricted on holidays and at certain other
            times

Instruct your bank to wire funds to:

Receiving Bank:          State Street Bank and Trust Company
                         225 Franklin Street
                         Boston, MA 02101
                         ABA Routing No. 011000028

For further credit to:   Shareholder Name
                         Existing Pioneer Account No.
                         [Name of Pioneer Fund]


                                       45


The transfer agent must receive your account application before you send your
initial check or federal funds wire. In addition, you must provide a bank wire
address of record when you establish your account.

Exchanging

You may, under certain circumstances, 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 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. Shares
you acquire as part of an exchange will continue to be subject to any
contingent deferred sales charge that applies to the shares you originally
purchased. When you ultimately sell your shares, the date of your original
purchase will determine your contingent deferred sales charge.

Before you request an exchange, consider each fund's investment objective and
policies as described in the fund's prospectus. You generally will have to pay
income taxes on an exchange.

Same-fund exchange privilege

Certain shareholders may be eligible to exchange their shares for the Pioneer
Fund's Class Y shares. If eligible, no sales charges or other charges will
apply to any such exchange. Generally, shareholders will not recognize a gain
or loss for federal income tax purposes upon such an exchange. Investors should
contact their financial intermediary to learn more about the details of this
privilege.

How to exchange shares

Through your investment firm

Normally, your investment firm will send your exchange request to the Pioneer
Fund's transfer agent. Consult your investment professional for more
information about exchanging your shares.

By phone or online

After you establish an eligible fund account, you can exchange shares of a
Pioneer Fund by phone or online if:

      o     You are exchanging into an existing account or using the exchange to
            establish a new account, provided the new account has a registration
            identical to the original account

      o     The fund into which you are exchanging offers the same class of
            shares

      o     You are not exchanging more than $500,000 worth of shares per
            account per day

      o     You can provide the proper account identification information


In writing, by mail or by fax

You can exchange shares of a Pioneer Fund by mailing or faxing a letter of
instruction to the fund. You can exchange shares of a Pioneer Fund directly
through the Pioneer Fund only if your account is registered in your name.
However, you may not fax an exchange request for more than $500,000. Include in
your letter:

      o     The name and signature of all registered owners

      o     A signature guarantee for each registered owner if the amount of the
            exchange is more than $500,000

      o     The name of the Pioneer Fund out of which you are exchanging and the
            name of the fund into which you are exchanging

      o     The class of shares you are exchanging

      o     The dollar amount or number of shares you are exchanging

Please note that there may be a delay in receipt by the fund's transfer agent
of exchange requests submitted by regular mail to a post office address.

Selling

Your shares will be sold at the share price (net asset value less any
applicable sales charge) next calculated after the Pioneer Fund or its
authorized agent, such as a broker-dealer, receives your request in good order.
If a signature guarantee is required, you must submit your request in writing.

                                       46


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 recently sent a check to purchase the
shares being sold, the Pioneer Fund may delay payment of the sale proceeds
until your check has cleared. This may take up to 10 calendar days from the
purchase date.

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

You generally will have to pay income taxes on a sale.

If you must use a written request to exchange or sell your shares and your
account is registered in the name of a corporation or other fiduciary you must
include the name of an authorized person and a certified copy of a current
corporate resolution, certificate of incumbency or similar legal document
showing that the named individual is authorized to act on behalf of the record
owner.

How to sell shares

Through your investment firm

Normally, your investment firm will send your request to sell shares to the
Pioneer Funds' transfer agent. Consult your investment professional for more
information. Each Pioneer Fund has authorized the distributor to act as its
agent in the repurchase of fund shares from qualified investment firms. Each
Pioneer Fund reserves the right to terminate this procedure at any time.

By phone or online

If you have an eligible non-retirement account, you may sell up to $100,000 per
account per day by phone or online. You may sell shares of a Pioneer Fund held
in a retirement plan account by phone only if your account is an eligible IRA
(tax penalties may apply). You may not sell your shares by phone or online if
you have changed your address (for checks) or your bank information (for wires
and transfers) in the last 30 days.

You may receive your sale proceeds:

      o     By check, provided the check is made payable exactly as your account
            is registered

      o     By bank wire or by electronic funds transfer, provided the sale
            proceeds are being sent to your bank address of record

For Class Y shares, shareholders may sell up to $5 million per account per day
if the proceeds are directed to your bank account of record ($100,000 per
account per day if the proceeds are not directed to your bank account of
record).

In writing, by mail or by fax

You can sell some or all of your shares of a Pioneer Fund by writing directly
to the Pioneer Fund only if your account is registered in your name. Include in
your request your name, the name of the Pioneer Fund, your fund account number,
the class of shares to be sold, the dollar amount or number of shares to be
sold and any other applicable requirements as described below. The transfer
agent will send the sale proceeds to your address of record unless you provide
other instructions. Your request must be signed by all registered owners and be
in good order.

The transfer agent will not process your request until it is received in good
order.

You may sell up to $100,000 per account per day by fax.

Account options

See the account application form for more details on each of the following
services or call the transfer agent for details and availability.

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 fund.

When you request a telephone transaction the fund's 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. If a Pioneer Fund's
confirmation procedures are followed, neither the fund nor its agents will bear
any liability for these transactions.

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:

      o     For new accounts, complete the online section of the account
            application

      o     For existing accounts, complete an account options form, write to
            the transfer agent or complete the online authorization screen at
            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.

Automatic investment plans

You can make regular periodic investments in a Pioneer Fund by setting up
monthly bank drafts, government allotments, payroll deductions, a Pioneer
Investomatic Plan and other similar automatic investment plans. Automatic
investments may be made only through U.S. banks. You may use an automatic
investment plan to establish a Class A share account with a small initial
investment. If you have a Class C share account and your balance is at least
$1,000, you may establish an automatic investment plan.

Pioneer Investomatic Plan

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

                                       48


Automatic exchanges

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

      o     You must select exchanges on a monthly or quarterly basis

      o     Both the originating and receiving accounts must have identical
            registrations

      o     The originating account must have a minimum balance of $5,000

You may have to pay income taxes on an exchange.

Distribution options

Each Pioneer Fund offers three distribution options. Any shares of a Pioneer
Fund 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 a Pioneer
            Fund will automatically be invested in additional fund shares.

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

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


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

If you are under 59 1/2, taxes and tax penalties may apply.

If your distribution check is returned to the transfer agent or you do not cash
the check for six months or more, the transfer agent may reinvest the amount of
the check in your account and automatically change the distribution option on
your account to option (1) until you request a different option in writing. If
the amount of a distribution check would be less than $25, the Pioneer Fund may
reinvest the amount in additional shares of the fund instead of sending a
check. Additional shares of the Pioneer Fund 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.

Systematic withdrawal plans

When you establish a systematic withdrawal plan for your account, the transfer
agent will sell the number of fund shares you specify on a periodic basis and
the proceeds will be paid to you or to any person you select. You must obtain a
signature guarantee to direct payments to another person after you have
established your systematic withdrawal plan. Payments can be made either by
check or by electronic transfer to a U.S. bank account you designate.

To establish a systematic withdrawal plan:

      o     Your account must have a total value of at least $10,000 when you
            establish your plan

      o     You may not request a periodic withdrawal of more than 10% of the
            value of any Class C share account (valued at the time the plan is
            implemented)

These requirements do not apply to scheduled (Internal Revenue Code Section
72(t) election) or mandatory (required minimum distribution) withdrawals from
IRAs and certain retirement plans.

Systematic sales of fund shares may be taxable transactions for you. While you
are making systematic withdrawals from your account, you may pay unnecessary
initial sales charges on additional purchases of Class A shares or contingent
deferred sales charges.

                                       49


Direct deposit

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

Voluntary tax withholding

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

Shareholder services and policies

Excessive trading

Frequent trading into and out of a Pioneer Fund can disrupt portfolio
management strategies, harm the Pioneer Fund's performance by forcing the
Pioneer 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 Pioneer 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. Each Pioneer 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 a Pioneer 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 indicate a timing
            pattern or strategy; or

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

Each Pioneer Fund's Board of Trustees has adopted policies and procedures with
respect to frequent purchases and redemptions of fund shares by investors in
the Pioneer Fund. 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 or other
intermediary has engaged in excessive short-term trading that we believe may be
harmful to a Pioneer Fund, we will ask the investor, broker or other
intermediary to cease such activity and we will refuse to process purchase
orders (including purchases by exchange) of such investor, broker, other
intermediary 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 shareholders of the Pioneer Fund.

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 a Pioneer Fund may be adversely affected.
Frequently, shares of a Pioneer Fund 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 or other intermediary, are aggregated. Our
ability to monitor trading practices by investors purchasing shares through
omnibus accounts may be limited and dependent upon the cooperation of the
broker or other intermediary in taking steps to limit this type of activity.

Each Pioneer Fund may reject a purchase or exchange order before its acceptance
or the issuance of shares. Each Pioneer Fund may also restrict additional
purchases or exchanges in an account. Each of these steps may be taken for any
transaction, for any reason, without prior notice, including transactions that
the Pioneer Fund believes are requested on behalf of market timers. Each
Pioneer Fund reserves the right to reject any purchase or exchange request by
any investor or financial institution if the Pioneer 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 had been accepted and
an investment made in the fund. A Pioneer Fund and its shareholders do not
incur any gain or loss as a result of a rejected order. Each Pioneer Fund may
impose further restrictions on trading activities by market timers in the
future.

To limit the negative effects of excessive trading, each Pioneer Fund has
adopted the following restriction on investor transactions. If an investor
redeems $5,000 or more (including redemptions that are a part of an exchange
transaction) from a Pioneer Fund, that investor shall be prevented (or
"blocked") from purchasing shares of the Pioneer Fund (including purchases that
are a part of an exchange transaction) for 30 calendar days after the
redemption. This policy does not apply to systematic purchase or withdrawal
plan transactions, transactions made through employer-sponsored retirement
plans described under Section 401(a), 403(b) or 457 of the Internal Revenue
Code or employee benefit plans, scheduled (Internal Revenue Code Section 72(t)
election) or mandatory (required minimum distribution) withdrawals

                                       50


from IRAs, rebalancing transactions made through certain asset allocation or
"wrap" programs, transactions by insurance company separate accounts or
transactions by other funds that invest in the Pioneer Fund. This policy does
not apply to purchase or redemption transactions of less than $5,000 or to
Pioneer U.S. Government Money Market Fund or Pioneer Multi-Asset Ultrashort
Income Fund.

We rely on financial intermediaries that maintain omnibus accounts to apply to
their customers either the Pioneer Funds' policy described above or the
intermediaries' own policies or restrictions designed to limit excessive
trading of shares of a Pioneer Fund. However, we do not impose this policy at
the omnibus account level.

Purchases pursuant to the reinstatement privilege (for Class A shares) are
subject to this policy.

Purchases in kind

You may use securities you own to purchase shares of a Pioneer Fund provided
that Pioneer, in its sole discretion, determines that the securities are
consistent with the Pioneer Fund's objective and policies and their acquisition
is in the best interests of the Pioneer Fund. If the fund accepts your
securities, they will be valued for purposes of determining the number of
shares of the Pioneer Fund to be issued to you in the same way the fund will
value the securities for purposes of determining its net asset value. For
federal income tax purposes, you may be taxed in the same manner as if you sold
the securities that you use to purchase shares of the Pioneer Fund for cash in
an amount equal to the value of the shares of the Pioneer Fund that you
purchase. Your broker may also impose a fee in connection with processing your
purchase of shares of a Pioneer Fund with securities.

Reinstatement privilege (Class A shares)

If you recently sold all or part of your Class A shares, you may be able to
reinvest all or part of your sale proceeds without a sales charge in Class A
shares of any Pioneer mutual fund. To qualify for reinstatement:

      o     You must send a written request to the transfer agent no more than
            90 days after selling your shares and

      o     The registration of the account in which you reinvest your sale
            proceeds must be identical to the registration of the account from
            which you sold your shares.

Purchases pursuant to the reinstatement privilege are subject to limitations on
investor transactions, including the limitation on the purchase of a Pioneer
Fund's shares within 30 calendar days of redemption. See "Excessive trading."

When you elect reinstatement, you are subject to the provisions outlined in the
selected the Pioneer Fund's prospectus, including the fund's minimum investment
requirement. Your sale proceeds will be reinvested in shares of the Pioneer
Fund at the Class A net asset value per share determined after the transfer
agent receives your written request for reinstatement. You may realize a gain
or loss for federal income tax purposes as a result of your sale of shares of a
Pioneer Fund, and special tax rules may apply if you elect reinstatement.
Consult your tax adviser for more information.

      o     Make computer-assisted telephone purchases, exchanges and
            redemptions for your fund accounts


                                       51



      o     Request account statements

If you plan to use FactFone[SM] to make telephone purchases and redemptions,
first you must activate your personal identification number and establish your
bank account of record. If your account is registered in the name of a
broker-dealer or other third party, you may not be able to use FactFone[SM].

If your account is registered in the name of a broker-dealer or other third
party, you may not be able to use FactFone[SM] to obtain account information.

Household delivery of fund documents

With your consent, Pioneer may send a single proxy statement, prospectus and
shareowner report to your residence for you and any other member of your
household who has an account with a Pioneer Fund. If you wish to revoke your
consent to this practice, you may do so by notifying Pioneer, by phone or in
writing (see "How to contact us"). Pioneer will begin mailing separate proxy
statements, prospectuses and shareowner reports to you within 30 days after
receiving your notice.

Confirmation statements

The Pioneer Funds' transfer agent maintains an account for each investment firm
or individual shareowner and records all account transactions. You will be sent
confirmation statements showing the details of your transactions as they occur,
except automatic investment plan transactions, which are confirmed quarterly.
If you have more than one Pioneer mutual fund account registered in your name,
the Pioneer combined account statement will be mailed to you each quarter.

Tax information

Early each year, each Pioneer Fund will mail you information about the tax
status of the dividends and distributions paid to you by the Pioneer Fund.

Tax information for IRA rollovers

In January (or by the applicable Internal Revenue Service deadline) following
the year in which you take a reportable distribution, the Pioneer Funds'
transfer agent will mail you a tax form reflecting the total amount(s) of
distribution(s) received by the end of January.

Privacy

Each Pioneer Fund has a policy designed to protect the privacy of your personal
information. A copy of Pioneer's privacy notice was given to you at the time
you opened your account. Each Pioneer Fund will send you a copy of the privacy
notice each year. You may also obtain the privacy notice by calling the fund or
through Pioneer's website.

Signature guarantees and other requirements

You are required to obtain a signature guarantee when:

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

      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 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. A Pioneer Fund may accept other
forms of guarantee from financial intermediaries in limited circumstances.

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

                                       52


Minimum account size

The fund requires that you maintain a minimum account value of $500. If you
hold less than $500 in your account, each Pioneer 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 a Pioneer Fund by telephone or accessing
www.pioneerinvestments.com during times of market volatility or disruption in
telephone or Internet 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
access www.pioneerinvestments.com or reach a Pioneer Fund by telephone, you
should communicate with the Pioneer 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

Each Pioneer Fund and the distributor 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. Each Pioneer 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 Securities and Exchange Commission

Each Pioneer Fund reserves the right to:

      o     suspend transactions in shares when trading on the New York Stock
            Exchange is closed or restricted, or when the Securities and
            Exchange Commission determines an emergency or other circumstances
            exist that make it impracticable for the Pioneer Fund to sell or
            value its portfolio securities, or otherwise as permitted by the
            rules of or by the order of the Securities and Exchange Commission

      o     redeem in kind by delivering to you portfolio securities owned by
            the Pioneer 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

      o     charge transfer, shareholder servicing or similar agent fees, such
            as an account maintenance fee for small balance accounts, directly
            to accounts upon at least 30 days' notice. A Pioneer Fund may do
            this by deducting the fee from your distribution of dividends and/or
            by redeeming fund shares to the extent necessary to cover the fee

      o     close your account after a period of inactivity, as determined by
            state law, and transfer your shares to the appropriate state


Dividends, capital gains and taxes

Dividends and capital gains

Each Pioneer Fund declares dividends daily. The daily dividends consist of
substantially all of the Pioneer Fund's net income (excluding any net short-
and long-term capital gains). You begin to earn dividends on the first business
day following receipt of payment for shares. You continue to earn dividends up
to and including the date of sale. Dividends are normally paid on the last
business day of each month.

Each Pioneer Fund generally pays any distribution of net short- and long-term
capital gains in November. 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 a Pioneer Fund shortly before a
distribution described in this paragraph, generally you will pay a higher price
per share and, unless you are exempt from tax, you will pay taxes on the amount
of the distribution whether you reinvest the distribution in additional shares
or receive it as cash.

                                       53


Taxes

You will normally have to pay federal income taxes, and any state or local
taxes, on the dividends and other distributions you receive from a Pioneer
Fund, whether you take the distributions in cash or reinvest them in additional
shares. For U.S. federal income tax purposes, distributions from a Pioneer
Fund's net capital gains (if any) are considered long-term capital gains and
are generally taxable to noncorporate shareholders at rates of up to 20%.
Distributions from a Pioneer Fund's net short-term capital gains are generally
taxable as ordinary income. Other dividends are generally taxable as ordinary
income. Since the Pioneer Funds's income is derived primarily from sources that
do not pay dividends, it is not expected that a substantial portion of the
dividends paid by the Pioneer Funds will qualify either for the
dividends-received deduction for corporations or for any favorable U.S. federal
income tax rate available to noncorporate shareholders on "qualified dividend
income."

Each Pioneer Fund will report to shareholders annually the U.S. federal income
tax status of all fund distributions.

If a Pioneer Fund declares a dividend in October, November or December, payable
to shareholders of record in such a month, and pays it in January of the
following year, you will be taxed on the dividend as if you received it in the
year in which it was declared.

Sales and exchanges generally will be taxable transactions to shareowners. When
you sell or exchange Pioneer 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.

A 3.8% Medicare contribution tax generally applies to all or a portion of the
net investment income of a shareholder who is an individual and not a
nonresident alien for federal income tax purposes and who has adjusted gross
income (subject to certain adjustments) that exceeds a threshold amount. This
3.8% tax also applies to all or a portion of the undistributed net investment
income of certain shareholders that are estates and trusts. For these purposes,
dividends, interest and certain capital gains are generally taken into account
in computing a shareholder's net investment income.

You must provide your social security number or other taxpayer identification
number to the applicable Pioneer 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 Pioneer Fund will apply "backup
withholding" tax on your dividends and other distributions, sale proceeds and
any other payments to you that are subject to backup withholding. The backup
withholding rate is 28%.

Shareholders that are exempt from U.S. federal income tax, such as retirement
plans that are qualified under Section 401 of the Internal Revenue Code,
generally are not subject to U.S. federal income tax on Pioneer Fund dividends
or other distributions or on sales or exchanges of Pioneer Fund shares.
However, in the case of Pioneer Fund shares held through a nonqualified
deferred compensation plan, Pioneer Fund dividends and other distributions
received by the plan and sales and exchanges of Pioneer Fund shares by the plan
generally will be taxable to the employer sponsoring such plan in accordance
with U.S. federal income tax laws that are generally applicable to shareholders
receiving such dividends and other distributions from regulated investment
companies such as the applicable Pioneer Fund or effecting such sales or
exchanges.

Plan participants whose retirement plan invests in a Pioneer Fund generally are
not subject to federal income tax on the Pioneer Fund's dividends or other
distributions received by the plan or on sales or exchanges of the Pioneer
Fund's shares by the plan. However, distributions to plan participants from a
retirement plan generally are taxable to plan participants as ordinary income.

Distributions derived from interest on U.S. government obligations (but
generally not distributions of gain from the sale of such obligations) may be
exempt from certain state and local taxes.

You should ask your tax adviser about any federal, state, local and foreign tax
considerations relating to an investment in a Pioneer Fund. You may also
consult the Pioneer Fund's statement of additional information for a more
detailed discussion of the U.S. federal income tax considerations that may
affect the Pioneer Fund and its shareowners.

          3.4 If on the Closing Date (a) the New York Stock Exchange is closed
to trading or trading thereon shall be restricted or (b) trading or the
reporting of trading on such exchange or elsewhere is disrupted so that

Fund Board with respect to the Acquiring Fund and the Acquired Trust Board with
respect to the Acquired Fund), the Closing Date shall be postponed until the
first business day after the day when trading shall have been fully resumed and
reporting shall have been restored or such later date as may be mutually agreed
in writing by an authorized officer of each party.

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

Shares have been credited to the Acquired Fund's account on the books of the
Acquiring Fund. At the Closing, each party shall deliver to the other such
bills of sale, checks, assignments, stock certificates, receipts or other
documents as such other party or its counsel may reasonably request.

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 Trust to make the certifications
required by the Sarbanes-Oxley Act, and no deficiency, weakness, fraud, change,
event or other factor exists with respect to the Acquired Fund 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 or its statement of additional

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, a decline in net assets of the
Acquired Fund as a result of redemptions or the discharge of Acquired Fund
liabilities shall not constitute a material adverse change;

              (h) On the Closing Date, all federal and other tax returns,
dividend reporting forms and other tax-related reports of the Acquired Fund
required by law to have been filed (taking into account any extensions) shall

correct in all material respects, and all federal and other taxes shown as due
or required to be shown as due from the Acquired Fund on such tax returns,
forms and reports shall have been paid or provision shall have been made for
the payment thereof and, to the best of the Acquired Trust's knowledge, no such
return is currently under audit and no outstanding assessment of any tax has
been asserted with respect to such returns.

              (i) The Acquired Fund is a separate series of the Acquired
Trust treated as a separate corporation from each other series of the Acquired
Trust under Section 851(g) of the Code. For each taxable year of its existence,
including the taxable year ending on the Closing Date, the Acquired Fund has
had in effect an election to be treated as a "regulated investment company"
under Subchapter M of the Code, has satisfied or will satisfy all of the
requirements of Subchapter M of the Code for treatment as a regulated
investment company, and has been or will be eligible to compute its federal
income tax under Section 852 of the Code. On or before the Closing Date, the
Acquired Fund will have declared and paid dividends sufficient to distribute
substantially all of (a) the sum of (i) its net tax-exempt interest income,
(ii) its investment company taxable income (as defined in the Code, computed
without regard to any deduction for dividends paid) and (iii) any net capital
gain (as such term is used in Sections 852(b)(3)(A) and (C) of the Code) after
reduction by any available capital loss carryforwards, and (b) any other
amounts as necessary, in each case for all of its tax periods ending on or
before the Closing Date, as dividends qualifying for the dividends-paid
deduction under Section 561 of the Code, such that the Acquired Fund will have
no unpaid tax liability under Section 852 of the Code for any tax period ending
on or before the Closing Date.

                                      A-4


For each calendar year (including the calendar year that includes the Closing
Date), the Acquired Fund will have made such distributions on or before the
Closing Date as are necessary so that for all calendar years ending on or
before the Closing Date, and for the calendar year that includes the Closing
Date, such Acquired Fund will not have any unpaid tax liability under Section
4982 of the Code;

              (j) 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;

              (k) 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,
and, upon delivery and payment for the Acquired Assets, the Acquiring Fund will
acquire good and marketable title thereto, subject to no restrictions on the
full transfer thereof, except such restrictions as might arise under the
Securities Act;

              (l) The Acquired Trust has the trust power and authority, on
behalf of the Acquired Fund, to enter into 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 Acquired Trust's
Board of Trustees, and, assuming due authorization, execution and delivery by
the Acquiring Fund, this Agreement will constitute a valid and binding
obligation of the Acquired Trust, on behalf 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;

              (m) The information to be furnished by the Acquired Trust, on
behalf of the Acquired Fund, to the Acquiring Fund for use in applications for
orders, registration statements and other documents which may be necessary in
connection with the transactions contemplated hereby and any information
necessary to compute the total return of the Acquired Fund shall be accurate and
complete in all material respects and shall comply in all material respects with
federal securities and other laws and regulations applicable thereto or the
requirements of any form for which its use is intended, and shall not contain
any untrue statement of a material fact or omit to state a material fact
necessary to make the information provided not misleading;

              (n) No consent, approval, authorization or order of or filing with
any court or governmental authority is required for the execution of this
Agreement or the consummation of the transactions contemplated by this
Agreement by the Acquired Trust or the Acquired Fund, except such as may be

been offered for sale and sold in compliance in all material respects with
all applicable federal and state securities laws, except as may have been
previously disclosed in writing to the Acquiring Fund;

              (q) The current prospectus and statement of additional information
of the Acquired Fund and any amendments or supplements thereto did not as of
their dates or the dates of their distribution to the public contain any untrue

circumstances in which such statements were made, not materially misleading;

not materially misleading;

              (d) The Acquiring Fund's registration statement on Form N-1A that
will be in effect on the Closing Date, and the prospectus and statement of
additional information of the Acquiring Fund included therein, will conform in

undertaking with respect to the Acquiring Fund to which the Acquiring Fund is a
party or by which the Acquiring Fund or any of its assets is bound;

              (f) No litigation or administrative proceeding or investigation of

business. The Acquiring 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 Acquiring Fund's business or its ability to consummate the
transactions contemplated herein;

              (g) The Statement of Assets and Liabilities of the Acquiring Fund,

permits of federal, state and local regulatory authorities (including those of
the Commission and of state Blue Sky and securities authorities) deemed
necessary by either party hereto to permit consummation, in all material
respects, of the transactions contemplated hereby shall have been obtained,
except where failure to obtain any such consent, order or permit would not
involve a risk of a material adverse effect on the assets or properties of
either party hereto, provided that either party may waive any such conditions
for itself;

          8.3 The registration statement on Form N-14 filed in connection with
this Agreement shall have become effective under the Securities Act and no stop
order suspending the effectiveness of the registration statement shall have

          8.4 The parties shall have received an opinion of Morgan, Lewis &
Bockius LLP, satisfactory to the Acquired Trust and the Acquiring Fund and
subject to customary assumptions and qualifications, substantially to the
effect that, based upon certain facts, assumptions and representations, and
upon certifications contained in the Acquiring Fund Tax Representation
Certificate and the Acquired Fund Tax Representation Certificate, for federal
income tax purposes (i) the Reorganization will constitute a "reorganization"
within the meaning of Section 368(a) of the Code, and each of the Acquired Fund
and the Acquiring Fund will be a "party to a reorganization" within the meaning
of Section 368(b) of the Code; (ii) no gain or loss will be recognized by the
Acquired Fund in the Reorganization on the transfer of the Acquired Assets to
the Acquiring Fund solely in exchange for the Acquiring Fund Shares and the
assumption by the Acquiring Fund of the Assumed Liabilities, or upon the
distribution of the Acquiring Fund Shares to the shareholders of the Acquired
Fund in complete liquidation of the Acquired Fund, except for (A) gain or loss
that may be recognized with respect to "section 1256 contracts" as defined in
Section 1256(b) of the Code, (B) gain that may be recognized on the transfer of
stock in a "passive foreign investment company" as defined in Section 1297(a)
of the Code, and (C) any other gain or loss that may be required to be
recognized as a result of the closing of the Acquired Fund's taxable year or
upon the transfer of an asset regardless of whether such transfer would
otherwise be a non-recognition transaction under the Code; (iii) the tax basis
in the hands of the Acquiring Fund of the Acquired Assets will be the same as
the tax basis of such Acquired Assets in the hands of the Acquired Fund
immediately prior to the transfer thereof, increased by the amount of gain (or
decreased by the amount of loss), if any, recognized by the Acquired Fund on
the transfer; (iv) the holding period of each Acquired Asset transferred in the
Reorganization in the hands of the Acquiring Fund, other than assets with
respect to which gain or loss is required to be recognized in the
Reorganization, will include the period during which the Acquired Asset was
held by the Acquired Fund (except where investment activities of the Acquiring
Fund have the effect of reducing or eliminating the holding period with respect
to an asset); (v) no gain or loss will be recognized by the Acquiring Fund upon
its receipt of the Acquired Assets transferred in the Reorganization solely in
exchange for Acquiring Fund Shares and the assumption of the Assumed
Liabilities; (vi) no gain or loss will be recognized by the Acquired Fund
Shareholders upon the exchange of all of their Acquired Fund Shares for
Acquiring Fund Shares as part of the Reorganization; (vii) the aggregate tax
basis of the Acquiring Fund Shares that each Acquired Fund Shareholder receives
in the Reorganization will be the same as the aggregate tax basis of the
Acquired Fund Shares exchanged therefor; (viii) each Acquired Fund
Shareholder's holding period for the Acquiring Fund Shares received in the
Reorganization will include the holding period for the Acquired Fund Shares
exchanged therefor, provided that the Acquired Fund Shareholder held such
Acquired Fund Shares as capital assets on the date of exchange. Notwithstanding
anything in this Agreement to the contrary, neither the Acquired Fund nor the
Acquiring Fund may waive the condition set forth in this paragraph 8.4.

          8.5 The Acquired Trust, on behalf of the Acquired Fund, shall have
distributed to the Acquired Fund Shareholders, in a distribution or
distributions qualifying for the deduction for dividends paid under Section 561
of the Code, all of the Acquired Fund's investment company taxable income (as
defined in Section 852(b)(2) of the Code determined without regard to Section
852(b)(2)(D) of the Code) for its taxable year ending on the Closing Date, all
of the excess of (i) its interest income excludable from gross income under
Section 103(a) of the Code over (ii) its deductions disallowed under Sections
265 and 171(a)(2) of the Code for its taxable year ending on the Closing Date,
and all of its net capital gain (as such term is used in Sections 852(b)(3)(A)
and (C) of the Code), after reduction by any available capital loss
carryforward, for its taxable year ending on the Closing Date.

9.        BROKERAGE FEES AND EXPENSES

          9.1 Each party hereto represents and warrants to the other party
hereto that there are no brokers or finders entitled to receive any payments in
connection with the transactions provided for herein.

          9.2 The parties have been informed by Pioneer that it will pay 50% of
the expenses incurred in connection with the Reorganization (including, but not

of the Acquired Fund and the Acquiring Fund agrees to pay 25% of the expenses
incurred in connection with the Reorganization (including, but not limited to,
the preparation of the registration statement on Form N-14). Notwithstanding
any of the foregoing, expenses will in any event be paid by the party directly
incurring such expenses if and to the extent that the payment by another person
of such expenses would result in a failure by either Fund to qualify for
treatment as a "regulated investment company" within the meaning of Section 851
of the

                                      A-10


Code or would prevent the Reorganization from qualifying as a reorganization
within the meaning of Section 368 of the Code or otherwise result in the
imposition of tax on either Fund or on either Fund's shareholders.

10.       ENTIRE AGREEMENT; SURVIVAL OF WARRANTIES

          10.1 The Acquiring Fund and the Acquired Trust each agrees that

constitutes the entire agreement between the parties.

          10.2 The covenants to be performed after the Closing by both the
Acquiring Fund and the Acquired Trust shall survive the Closing. The
representations and warranties and all other covenants contained in this
Agreement or in any document delivered pursuant hereto or in connection
herewith shall not survive the consummation of the transactions contemplated
hereunder.

11.       TERMINATION

          11.1 This Agreement may be terminated by the mutual agreement of the
Acquiring Fund and the Acquired Trust. In addition, either party may at its
option terminate this Agreement at or prior to the Closing Date:

              (a) by resolution of the Acquiring Fund's Board of Trustees if
circumstances should develop that, in the good faith opinion of such Board, make
proceeding with the Agreement not in the best interests of the Acquiring Fund's
shareholders; or

              (b) by resolution of the Acquired Trust's Board of Trustees if
circumstances should develop that, in the good faith opinion of such Board, make
proceeding with the Agreement not in the best interests of the Acquired Fund's
shareholders.

          11.2 In the event of any such termination, there shall be no
liability for damages on the part of the Acquiring Fund, the Acquired Trust or
the Acquired Fund, or the trustees or officers of the Acquired Trust or the
Acquiring Fund, but, subject to Paragraph 9.2, each party shall bear the
expenses incurred by it incidental to the preparation and carrying out of this
Agreement.

(*) Attached as Exhibit A to the combined Information Statement/Prospectus

(**) 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 Securities Act of 1933, 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 Securities Act of 1933, 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 closing 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.
