                           Pioneer High Income Trust
                                 Common Shares
                                $15.00 per share
                             ----------------------

Investment Objective. Pioneer High Income Trust (the trust) is a newly organized, diversified, closed-end management investment company. The trust's investment objective is a high level of current income. The trust may, as a secondary objective, also seek capital appreciation to the extent consistent with its investment objective.

Portfolio Contents. Under normal market conditions, the trust invests at least 80% of its assets (net assets plus borrowing for investment purposes) in below investment grade (high yield) debt securities, loans and preferred stocks. These securities are rated Ba or lower by Moody's Investors Service, Inc.
(Moody's) or BB or lower by Standard & Poor's Ratings Group (Standard & Poor's)
or are unrated securities of comparable quality as determined by the trust's investment adviser. Because the trust's investments will be concentrated in high yield securities, it will be subject to risks of such securities. Below investment grade securities are commonly referred to as "junk bonds" and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. They involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. There can be no assurance that the trust will achieve its investment objective.

Investment Adviser. Pioneer Investment Management, Inc. (Pioneer) is the trust's investment adviser. See "Management of the Trust."

No Prior History. Because the trust is newly organized, its shares have no history of public trading. Shares of closed-end funds frequently trade at prices lower than their net asset value. The risk of loss due to this discount may be greater for initial investors expecting to sell their shares in a relatively short period after completion of the public offering. The trust has applied to list its common shares on the New York Stock Exchange under the symbol "PHH," subject to official notice of issuance.

Leverage. The trust may, but is not required to, issue preferred shares or borrow to the maximum extent permitted by the Investment Company Act of 1940, as amended. This practice is known as leverage. The trust may issue preferred stock or borrow from banks or other financial institutions. The trust may also borrow through reverse repurchase agreements and mortgage dollar rolls. The use of preferred shares or borrowing to leverage the common shares creates risks.

INVESTING IN THE TRUST'S COMMON SHARES INVOLVES RISKS THAT ARE DESCRIBED IN
THE "RISK FACTORS" SECTION BEGINNING ON PAGE 27 OF THIS PROSPECTUS.

Net proceeds, after expenses, to the trust..................   $14.295             $

The aggregate expenses of the offering are estimated to be $689,493. Pioneer has agreed to pay organizational expenses and offering costs (other than sales load) that exceed $0.03 per share. The underwriters may also purchase up to an additional common shares at the public offering price, less the sales load, within 45 days from the date of this prospectus to cover over-allotments.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

     The common shares will be ready for delivery on or about April   , 2002.

                              of current income. The trust may, as a secondary
                              objective, also seek capital appreciation to the
                              extent consistent with its investment objective.
                              There can be no assurance that the trust will
                              achieve its investment objective.

INVESTMENT POLICIES.........  The trust invests at least 80% of its assets (net
                              assets plus borrowing for investment purposes) in
                              below investment grade (high yield) debt
                              securities, loans and preferred stocks. These
                              securities are rated Ba or lower by Moody's or BB
                              or lower by Standard & Poor's or are unrated
                              securities of comparable quality as determined by
                              Pioneer, the trust's investment adviser. The trust
                              may invest in high yield securities of any rating,
                              including securities that are in default at the
                              time of purchase. Debt securities rated below
                              investment grade are commonly referred to as "junk
                              bonds" and are considered speculative with respect
                              to the issuer's capacity to pay interest and repay
                              principal. They involve greater risk of loss, are
                              subject to greater price volatility and are less
                              liquid, especially during periods of economic
                              uncertainty or change, than higher rated debt
                              securities. The trust's investments in high yield
                              securities may have fixed or variable principal
                              payments and all types of interest rate and
                              dividend payment and reset terms, including fixed
                              rate, adjustable rate, zero coupon, contingent,
                              deferred, payment in kind and auction rate
                              features. The trust invests in securities with a
                              broad range of maturities.

                              Convertible Securities.  The trust's investments
                              in fixed income securities may include bonds and
                              preferred stocks that are convertible into the
                              equity securities of the issuer. The trust will
                              not

                                        4

                              invest more than 50% of its total assets in
                              convertible instruments. Depending upon the
                              relationship of the conversion price to the market
                              value of the underlying securities, convertible
                              securities may trade more like equity securities
                              than debt instruments.

                              Loans.  The trust may invest a portion of its
                              assets in loan participations and other direct
                              claims against a borrower. The corporate loans in
                              which the trust invests primarily consist of
                              direct obligations of a borrower and may include
                              debtor in possession financings pursuant to
                              Chapter 11 of the U.S. Bankruptcy Code,
                              obligations of a borrower issued in connection
                              with a restructuring pursuant to Chapter 11 of the
                              U.S. Bankruptcy Code, leveraged buy-out loans,
                              leveraged recapitalization loans, receivables
                              purchase facilities, and privately placed notes.
                              The trust may invest in a corporate loan at
                              origination as a co-lender or by acquiring in the
                              secondary market participations in, assignments of
                              or novations of a corporate loan. By purchasing a
                              participation, the trust acquires some or all of
                              the interest of a bank or other lending
                              institution in a loan to a corporate or government
                              borrower.

                              Distressed Securities.  The trust may invest up to
                              10% of its total assets in distressed securities,
                              including corporate loans, which are the subject
                              of bankruptcy proceedings or otherwise in default
                              as to the repayment of principal and/or payment of
                              interest at the time of acquisition by the trust
                              or are rated in the lower rating categories (Ca or
                              lower by Moody's or CC or lower by Standard &
                              Poor's) or which are unrated investments
                              considered by Pioneer to be of comparable quality.
                              An investment in distressed securities is
                              speculative and involves significant risk.
                              Distressed securities frequently do not produce
                              income while they are outstanding and may require
                              the trust to bear certain extraordinary expenses
                              in order to protect and recover its investment.
                              Therefore, to the extent the trust seeks capital
                              appreciation through investment in distressed
                              securities, the trust's ability to achieve current
                              income for its shareholders may be diminished. The
                              trust also will be subject to significant
                              uncertainty as to when, in what manner and for
                              what value the obligations evidenced by the
                              distressed securities will eventually be satisfied
                              (e.g., through a liquidation of the obligor's
                              assets, an exchange offer or plan of
                              reorganization involving the distressed securities
                              or a payment of some amount in satisfaction of the
                              obligation).

                              Foreign Issuers.  While the trust primarily
                              invests in securities of U.S. issuers, the trust
                              may invest up to 25% of its total assets in
                              securities of corporate and governmental issuers
                              located outside the United States and denominated
                              in foreign currencies, including debt and equity
                              securities of corporate issuers and debt
                              securities of government issuers in developed and
                              emerging markets.

                              Illiquid Securities.  The trust may invest up to
                              50% of its total assets in illiquid securities,
                              which are securities that can not be disposed of
                              by the trust within seven days in the ordinary
                              course of business at approximately the amount at
                              which the trust values the

                                        5

                              securities. Pioneer anticipates that its research
                              efforts and investment approach will result in a
                              significant portion of the trust's assets being
                              invested in thinly traded securities. The trust
                              may invest in securities that are sold in direct
                              private placement transactions and are neither
                              listed on an exchange nor traded in the
                              over-the-counter market.


                              Mortgage- and Asset-Backed Securities and Real
                              Estate Investment Trusts (REITs).  The trust may
                              invest in mortgage- and asset-backed securities.
                              Mortgage-backed securities may be issued by
                              private companies or agencies of the U.S.
                              government and represent direct or indirect
                              participation in, or are collateralized by and
                              payable from, mortgage loans secured by real
                              property. Asset-backed securities represent
                              participations in and are secured by and payable
                              from assets such as installment sales or loan
                              contracts, leases, credit card receivables and
                              other categories of receivables. REITs are
                              companies that invest primarily in real estate or
                              real estate related loans. Interests in REITs are
                              significantly affected by the market for real
                              estate and are dependent upon management's skills
                              and cash flows.

                              Mortgage Dollar Rolls.  The trust may enter into
                              mortgage dollar roll transactions to earn
                              additional income. In these transactions, the
                              trust sells a U.S. agency mortgage-backed security
                              and simultaneously agrees to repurchase 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 trust loses the right to receive
                              interest and principal payments on the security it
                              sold. However, the trust benefits from the
                              interest earned on investing the proceeds of the
                              sale and may receive a fee or a lower repurchase
                              price. The benefits from these transactions depend
                              upon Pioneer's ability to forecast mortgage
                              prepayment patterns on different mortgage pools.
                              The trust 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.

                              Strategic Transactions.  The trust may use futures
                              and options on securities, indices and currencies,
                              forward foreign currency exchange contracts, swap
                              contracts and other derivatives. A derivative is a
                              security or instrument whose value is determined
                              by reference to the value or the change in value
                              of one or more securities, currencies, indices or
                              other financial instruments. The trust does not
                              use derivatives as a primary investment technique
                              and generally limits their use to hedging.
                              However, the trust may use derivatives for a
                              variety of non-principal purposes, including:

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

                              -   As a substitute for purchasing or selling
                                  securities; and

6

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

Other Securities. Normally, the trust invests substantially all of its assets to meet its investment objective. The trust may invest the remainder of its assets in securities with remaining maturities of less than one year, equity securities, cash equivalents or may hold cash. For temporary defensive purposes, the trust may depart from its principal investment strategies and invest part or all of its assets in these securities or may hold cash. During such periods, the trust may not be able to achieve its investment objective.

USE OF LEVERAGE BY THE

TRUST.......................  The trust may, but is not required to, issue
                              preferred shares, borrow money or issue debt
                              securities to the maximum extent permitted by the
                              Investment Company Act of 1940, as amended (1940
                              Act). This practice is known as leverage. The
                              trust currently anticipates that it will issue
                              preferred shares, as soon as practicable after the
                              closing of this offering, with an aggregate
                              liquidation preference of up to 25% of the trust's
                              total assets, but will be permitted to incur
                              leverage in an amount up to 33 1/3% of the trust's
                              total assets. The trust may not be leveraged at
                              all times and the amount of borrowing or leverage,
                              if any, may vary depending upon a variety of
                              factors, including Pioneer's outlook for the high
                              yield market and the costs that the trust would
                              incur as a result of such leverage. The trust may
                              issue preferred shares in the public or private
                              markets or may borrow from banks and other
                              financial institutions. The trust may also borrow
                              through reverse repurchase agreements and mortgage
                              dollar rolls. Leverage involves greater risks. The
                              trust's leveraging strategy may not be successful.
                              By leveraging its investment portfolio, the trust
                              creates an opportunity for increased net income or
                              capital appreciation. However, the use of leverage
                              also involves risks, which can be significant.
                              These risks include the possibility that the value
                              of the assets acquired with such borrowing
                              decreases although the trust's liability is fixed,
                              greater volatility in the trust's net asset value
                              and the market price of the trust's common shares
                              and higher expenses. Since Pioneer's fee is based
                              upon a percentage of the trust's total assets, the
                              investment adviser's fee will be higher if the
                              trust is leveraged and Pioneer will have an
                              incentive to be more aggressive and leverage the
                              trust. Pioneer intends only to leverage the trust
                              when it believes that the potential return on such
                              additional investments is likely to exceed the
                              costs incurred in connection with the borrowing.

INVESTMENT ADVISER..........  Pioneer is the trust's investment adviser. Pioneer
                              is responsible on a day-to-day basis for
                              investment of the trust's portfolio in accordance
                              with its investment objective and policies.
                              Pioneer makes all investment decisions for the
                              trust and places purchase and sale orders for the
                              trust's portfolio securities.

                              Pioneer or its predecessors have been managing
                              investment companies since 1928. Pioneer is an
                              indirect, majority owned subsidiary of UniCredito
                              Italiano S.p.A. (UniCredito), one of the

                                        7

                              leading banking groups in Italy. As of December
                              31, 2001, Pioneer and its affiliates had
                              approximately $99 billion in assets under
                              management worldwide, including over $19 billion
                              in U.S. open-end and closed-end investment
                              companies.

                              The trust pays Pioneer a fee for its investment
                              advisory services equal to 0.60% of the trust's
                              average weekly managed assets. This fee is payable
                              monthly. "Managed assets" means the total assets
                              of the trust (including any assets attributable to
                              any leverage that may be outstanding) minus the
                              sum of accrued liabilities (other than debt
                              representing financial leverage).

                              Day-to-day management of the trust's portfolio is
                              the responsibility of a team of fixed income
                              portfolio managers led by Kenneth J. Taubes. The
                              team manages other Pioneer mutual funds investing
                              primarily in fixed income securities. Mr. Taubes
                              is responsible for overseeing the U.S. and global
                              fixed income team. He joined Pioneer as a senior
                              vice president in September 1998 and has been an
                              investment professional since 1982. Prior to
                              joining Pioneer, Mr. Taubes had served since 1991
                              as a senior vice president and senior portfolio
                              manager for several institutional accounts and
                              mutual funds at another investment adviser.

LISTING.....................  Currently, there is no public market for the
                              trust's common shares. However, the trust has
                              applied to list its common shares on the New York
                              Stock Exchange under the trader or "ticker" symbol
                              "PHH," subject to official notice of issuance.

CUSTODIAN AND TRANSFER
AGENT.......................  Brown Brothers Harriman & Co. will serve as the
                              trust's custodian, and Pioneer Investment
                              Management Shareholder Services, Inc. will serve
                              as the trust's transfer agent. The transfer agent
                              has engaged Mellon Investor Services LLC as
                              sub-transfer agent, registrar, shareholder
                              servicing agent and dividend dispersing agent.


ADMINISTRATOR...............  Pioneer has engaged Princeton Administrators L.P.,
                              an affiliate of Merrill Lynch, Pierce, Fenner and
                              Smith Incorporated, to provide certain
                              administrative services for the trust. Pioneer
                              (and not the trust) will pay the administrator a
                              monthly fee computed at an annual rate of 0.10% of
                              the trust's total managed assets, subject to a
                              minimum monthly fee of $10,000.

MARKET PRICE OF COMMON
SHARES......................  Common shares of closed-end investment companies
                              frequently trade at prices lower than their net
                              asset value. Common shares of closed-end
                              investment companies like the trust that invest
                              predominately in high yield securities have during
                              some periods traded at prices higher than their
                              net asset value and during other periods traded at
                              prices lower then their net asset value. The trust
                              cannot assure you that its common shares will
                              trade at a price higher than or equal to net asset
                              value. The trust's net asset value will be reduced
                              immediately following this offering by the sales
                              load and the amount of the organization and
                              offering expenses paid by the trust. See "Use of
                              Proceeds." In addition to net asset value, the

                                        8

                              market price of the trust's common shares may be
                              affected by such factors as the trust's use of
                              leverage, dividend stability, portfolio credit
                              quality, liquidity, market supply and demand, the
                              trust's dividends paid (which are in turn affected
                              by expenses), call protection for portfolio
                              securities and interest rate movements. See
                              "Leverage," "Risk Factors" and "Description of
                              Shares." The trust's common shares are designed
                              primarily for long-term investors, and you should
                              not purchase common shares if you intend to sell
                              them shortly after purchase.

DISTRIBUTIONS...............  The trust intends to distribute to common
                              shareholders all or a portion of its net
                              investment income monthly and net realized capital
                              gains, if any, at least annually. The trust
                              expects that it will commence paying dividends
                              within 90 days of the date of this prospectus. At
                              times, in order to maintain a stable level of
                              distributions, the trust may pay out less than all
                              of its net investment income or pay out
                              accumulated undistributed income in addition to
                              current net investment income.

                              Dividend and capital gains distributions generally
                              are used to purchase additional common shares of
                              the trust. However, an investor can choose to
                              receive distributions in cash. Since not all
                              investors can participate in the automatic
                              dividend reinvestment plan, you should contact
                              your broker or nominee to confirm that you are
                              eligible to participate in the plan.

RISKS.......................  No Operating History.  The trust is a newly
                              organized closed-end management investment company
                              and has no operating history or history of public
                              trading.

                              Market Discount Risk.  Shares of closed-end funds
                              frequently trade at prices lower than their net
                              asset value. This is commonly referred to as
                              "trading at a discount." This characteristic of
                              shares of closed-end funds is a risk separate and
                              distinct from the risk that the trust's net asset
                              value may decrease. Investors who sell their
                              shares within a relatively short period after
                              completion of the public offering are likely to be
                              exposed to this risk. Accordingly, the trust is
                              designed primarily for long-term investors and
                              should not be considered a vehicle for trading
                              purposes. Net asset value will be reduced
                              following the offering by the underwriting
                              discount and the amount of offering expenses paid
                              by the trust.

                              High Yield Debt Securities.  Investment in high
                              yield securities involves substantial risk of
                              loss. Below investment grade debt securities or
                              comparable unrated securities are commonly
                              referred to as "junk bonds" and are considered
                              predominantly speculative with respect to the
                              issuer's ability to pay interest and principal and
                              are susceptible to default or decline in market
                              value due to adverse economic and business
                              developments. The market values for high yield
                              securities tend to be very volatile, and these
                              securities are less

                                        9

                              liquid than investment grade debt securities. For
                              these reasons, your investment in the trust is
                              subject to the following specific risks:

                              -   Increased price sensitivity to changing
                                  interest rates and to a deteriorating economic
                                  environment;

                              -   Greater risk of loss due to default or
                                  declining credit quality;

                              -   Adverse company specific events are more
                                  likely to render the issuer unable to make
                                  interest and/or principal payments; and

                              -   If a negative perception of the high yield
                                  market develops, the price and liquidity of
                                  high yield securities may be depressed. This
                                  negative perception could last for a
                                  significant period of time.

                              Adverse changes in economic conditions are more
                              likely to lead to a weakened capacity of a high
                              yield issuer to make principal payments and
                              interest payments than an investment grade issuer.
                              The principal amount of high yield securities
                              outstanding has proliferated in the past decade as
                              an increasing number of issuers have used high
                              yield securities for corporate financing. An
                              economic downturn could severely affect the
                              ability of highly leveraged issuers to service
                              their debt obligations or to repay their
                              obligations upon maturity.

                              The secondary market for high yield securities may
                              not be as liquid as the secondary market for more
                              highly rated securities, a factor which may have
                              an adverse effect on the trust's ability to
                              dispose of a particular security. There are fewer
                              dealers in the market for high yield securities
                              than investment grade obligations. The prices
                              quoted by different dealers may vary significantly
                              and the spread between the bid and asked price is
                              generally much larger than for higher quality
                              instruments. Under adverse market or economic
                              conditions, the secondary market for high yield
                              securities could contract further, independent of
                              any specific adverse changes in the condition of a
                              particular issuer, and these instruments may
                              become illiquid. As a result, the trust could find
                              it more difficult to sell these securities or may
                              be able to sell the securities only at prices
                              lower than if such securities were widely traded.
                              Prices realized upon the sale of such lower rated
                              or unrated securities, under these circumstances,
                              may be less than the prices used in calculating
                              the trust's net asset value.

                              Interest Rate Risk.  In addition to the risks
                              discussed above, high yield securities are subject
                              to certain risks, including:

                              -   If interest rates go up, the value of debt
                                  securities in the trust's portfolio generally
                                  will decline;

                              -   During periods of declining interest rates,
                                  the issuer of a security may exercise its
                                  option to prepay principal earlier than
                                  scheduled, forcing the trust to reinvest in
                                  lower yielding securities. This is known as
                                  call or prepayment risk. High yield securities
                                  frequently have call features that allow the
                                  issuer to

                                        10

                                  repurchase the security prior to its stated
                                  maturity. An issuer may redeem a high yield
                                  obligation if the issuer can refinance the
                                  debt at a lower cost due to declining interest
                                  rates or an improvement in the credit standing
                                  of the issuer;

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

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

                              Convertible Securities.  The trust may invest up
                              to 50% of its total assets in 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 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.

                              Corporate Loans.  The trust may acquire interests
                              in loans made by banks or other financial
                              institutions to corporate issuers or participation
                              interests in such loans. By purchasing a
                              participation interest in a loan, the trust
                              acquires some or all of the interest of a bank or
                              other lending institution in a loan to a corporate
                              or government borrower. The participations
                              typically will result in the trust having a
                              contractual relationship only with the lender, not
                              the borrower. The trust will have the right to
                              receive payments of principal, interest and any
                              fees to which it is entitled only from the lender
                              selling the participation and only upon receipt by
                              the lender of the payments from the borrower. If
                              the trust only acquires a participation in the
                              loan made by a third party, the trust may not be
                              able to control the exercise of any remedies that
                              the lender would have under the corporate loan.
                              These arrangements are designed to give corporate
                              loan investors preferential treatment over high
                              yield investors in the event of a deterioration in
                              the credit quality of the issuer. Even when these
                              arrangements exist, however, there can be no
                              assurance that the principal and interest owed on
                              the corporate loan will be repaid in full.
                              Corporate loans generally bear interest at rates
                              set at a margin above a generally recognized

                                        11

                              base lending rate that may fluctuate on a
                              day-to-day basis, in the case of the prime rate of
                              a U.S. bank, or which may be adjusted on set
                              dates, typically 30 days but generally not more
                              than one year, in the case of the London Interbank
                              Offered Rate. Consequently, the value of corporate
                              loans held by the trust may be expected to
                              fluctuate significantly less than the value of
                              other fixed rate high yield instruments as a
                              result of changes in the interest rate
                              environment. On the other hand, the secondary
                              dealer market for certain corporate loans may not
                              be as well developed as the secondary dealer
                              market for high yield bonds and, therefore,
                              presents increased market risk relating to
                              liquidity and pricing concerns.

                              Illiquid Investments.  The trust may invest up to
                              50% of its total assets in illiquid securities.
                              Illiquid securities may be difficult to dispose of
                              at a fair price at the times when the trust
                              believes it is desirable to do so. The market
                              price of illiquid securities generally is more
                              volatile than that of more liquid securities,
                              which may adversely affect the price that the
                              trust pays for or recovers upon the sale of
                              illiquid securities. Illiquid securities are also
                              more difficult to value and Pioneer's judgement
                              may play a greater role in the valuation process.
                              Investment of the trust's assets in illiquid
                              securities may restrict the trust's ability to
                              take advantage of market opportunities. The risks
                              associated with illiquid securities may be
                              particularly acute in situations in which the
                              trust's operations require cash and could result
                              in the trust borrowing to meet its short-term
                              needs or incurring losses on the sale of illiquid
                              securities.

                              Foreign Securities.  Investments in non-U.S.
                              issuers may involve unique risks compared to
                              investing in securities of U.S. issuers. These
                              risks are more pronounced to the extent that the
                              trust invests a significant portion of its
                              non-U.S. investments in one region or in the
                              securities of emerging market issuers. These risks
                              may include:

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

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

                              -   Adverse effect of currency exchange rates or
                                  controls on the value of the trust's
                                  investments;

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

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

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

                                        12

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

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

                              Leverage.  The trust may issue preferred shares,
                              borrow money or issue debt securities to the
                              maximum extent permitted by the 1940 Act. Leverage
                              creates risks which may adversely affect the
                              return for the holders of common shares,
                              including:

                              -   the likelihood of greater volatility of net
                                  asset value and market price of the trust's
                                  common shares;

                              -   fluctuations in the dividend rates on any
                                  preferred shares or in interest rates on
                                  borrowings and short-term debt;

                              -   increased operating costs, which may reduce
                                  the trust's total return; and

                              -   the potential for a decline in the value of an
                                  investment acquired with borrowed funds, while
                                  the trust's obligations under such borrowing
                                  remain fixed.

                              To the extent the income or capital appreciation
                              derived from securities purchased with funds
                              received from leverage exceeds the cost of
                              leverage, the trust's return will be greater than
                              if leverage had not been used. Conversely, if the
                              income or capital appreciation from the securities
                              purchased with such funds is not sufficient to
                              cover the cost of leverage or if the trust incurs
                              capital losses, the return of the trust will be
                              less than if leverage had not been used, and
                              therefore the amount available for distribution to
                              shareholders as dividends and other distributions
                              will be reduced or potentially eliminated.

                                        13

                              Certain types of borrowings may result in the
                              trust being subject to covenants in credit
                              agreements, including those relating to asset
                              coverage, borrowing base and portfolio composition
                              requirements and additional covenants that may
                              affect the trust's ability to pay dividends and
                              distributions on common shares in certain
                              instances. The trust may also be required to
                              pledge its assets to the lenders in connection
                              with certain types of borrowing. The trust may be
                              subject to certain restrictions on investments
                              imposed by guidelines of one or more nationally
                              recognized rating organizations which may issue
                              ratings for the preferred shares or short-term
                              debt instruments issued by the trust. These
                              guidelines may impose asset coverage or portfolio
                              composition requirements that are more stringent
                              than those imposed by the 1940 Act.

                              Recent Events.  The terrorist attacks in the
                              United States on September 11, 2001 had a
                              disruptive effect on the securities markets. The
                              trust does not know how long the securities
                              markets will continue to be affected by these
                              events and cannot predict the effects of similar
                              events in the future on the U.S. economy. High
                              yield securities tend to be more volatile than
                              higher rated fixed income securities so that these
                              events and any actions resulting from them may
                              have a greater impact on the prices and volatility
                              of high yield debt instruments than on higher
                              rated fixed income securities.

                              Anti-takeover Provisions.  The trust's Declaration
                              of Trust and by-laws include provisions that could
                              limit the ability of other entities or persons to
                              acquire control of the trust or to change the
                              composition of its Board of Trustees. Such
                              provisions could limit the ability of shareholders
                              to sell their shares at a premium over prevailing
                              market prices by discouraging a third party from

seeking to obtain control of the trust. These provisions include staggered terms of office for the Trustees, advance notice requirements for shareholder proposals, and super-majority voting requirements for open-ending the trust or a merger, liquidation, asset sales and similar transactions.

SUMMARY OF TRUST EXPENSES

The following table shows the trust's expenses as a percentage of net assets attributable to common shares assuming the use of leverage through the issuance of preferred shares in an amount equal to 25% of the trust's total managed assets. "Managed assets" means the total assets of the trust (including any assets attributable to any leverage that may be outstanding) minus the sum of accrued liabilities (other than debt representing financial leverage). The liquidation preference of the preferred shares is not a liability.

(1) The trust will bear expenses in connection with the offering in an amount up to $0.03 per share. Pioneer has agreed to pay organizational expenses and offering costs (other than sales load) that exceed $0.03 per share. If the trust completes an offering of preferred shares, the trust will also pay expenses in connection with such offering.

(2) A shareholder that directs the plan agent to sell shares held in a dividend reinvestment account will pay brokerage charges.

(3) The table above shows the estimated expenses that you will bear as a holder of common shares, assuming the trust issues preferred shares in an amount equal to 25% of the trust's total managed assets, stated as percentage of the trust's net assets attributable to common shares. The table below shows the estimated expenses of the trust assuming the trust does not issue preferred shares or otherwise utilize leverage.

The purpose of the tables in this section is to assist you in understanding the various costs and expenses that a shareholder will bear directly or indirectly by investing in the trust's common shares. As of the date of this prospectus, the trust has not commenced investment operations. The amount set forth under other expenses is based upon estimates for the current year, assuming no exercise of the over-allotment option granted to the underwriters. The table assumes that the trust issues 30,000,000 common shares and issues preferred shares as a means of leverage. If the trust issues fewer common shares, all other things being equal, these expenses would increase. If the trust leverages through borrowing, the trust would incur interest expense. For additional information with respect to the trust's expenses, see "Management of the Trust." Other expenses include custodial and transfer agency fees,

15

reimbursement of Pioneer for certain administrative expenses, legal and accounting expenses, and listing fees.

EXAMPLE:

The following example illustrates the expenses (including the sales load of $45.00) that you would pay on a $1,000 investment in common shares, assuming
(1) total net annual expenses of 0.96% of net assets attributable to common shares and (2) a 5% annual return:*

                                                        1 YEAR    3 YEARS    5 YEARS    10 YEARS

Total Expenses Incurred...............................   $54        $74       $ 96        $158


* THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE EXPENSES. The example assumes that the estimated other expenses set forth in the fee table are accurate and that all dividends and distributions are reinvested at net asset value. Actual expenses may be greater or less than those assumed. Moreover, the trust's actual rate of return may be greater or less than the hypothetical 5% return shown in the example.

THE TRUST

Pioneer High Income Trust is a newly organized, diversified, closed-end management investment company. The trust was organized under the laws of the state of Delaware on January 30, 2002, and has registered under the 1940 Act. As a recently organized entity, the trust has no operating history. The trust's principal office is located at 60 State Street, Boston, Massachusetts 02109, and its telephone number is (617) 742-7825.

USE OF PROCEEDS

The net proceeds of this offering will be approximately $ (or approximately $ assuming the underwriters exercise the over-allotment option in full) after payment of offering costs estimated to be approximately $ and the deduction of the sales load.

The trust will invest the net proceeds of the offering in accordance with its investment objective and policies as stated below. However, due to current illiquidity in the high yield debt markets, investments that, in the judgment of Pioneer, are appropriate investments for the trust may not be immediately available. Therefore, the trust expects that there will be an initial investment period of up to three months following the completion of its common shares offering before it is invested in accordance with its investment objective and policies. Pending such investment, the trust anticipates that all or a portion of the proceeds will be invested in U.S. government securities or high grade, short-term money market instruments. See "Investment Objective and Principal Investment Strategies."

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES

INVESTMENT OBJECTIVE

The trust's investment objective is a high level of current income. The trust may, as a secondary objective, also seek capital appreciation to the extent consistent with its investment objective. The trust's investment objective is a fundamental policy and may not be changed without the approval of a majority of the outstanding voting securities (as defined in the 1940 Act) of the trust. The trust makes no assurance that it will realize its objective.

16

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the trust invests at least 80% of its assets (net assets plus borrowing for investment purposes) in below investment grade debt securities, loans and preferred stocks. This is a non-fundamental policy and may be changed by the Board of Trustees of the trust provided that shareholders are provided with at least 60 days prior written notice of any change as required by the rules under the 1940 Act.

High Yield Securities. The high yield securities in which the trust invests are rated Ba or lower by Moody's or BB or lower by Standard & Poor's or are unrated but determined by Pioneer to be of comparable quality. Debt securities rated below investment grade are commonly referred to as "junk bonds" and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. Below investment grade debt securities involve greater risk of loss, are subject to greater price volatility and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities. An investment in the trust may be speculative in that it involves a high degree of risk and should not constitute a complete investment program. See "Risk Factors." For purposes of the trust's credit quality policies, if a security receives different ratings from nationally recognized securities rating organizations, the trust will use the rating chosen by the portfolio manager as most representative of the security's credit quality. The trust's high yield securities may have fixed or variable principal payments and all types of interest rate and dividend payment and reset terms, including fixed rate, adjustable rate, zero coupon, contingent, deferred, payment in kind and auction rate features. The trust invests in high yield securities with a broad range of maturities.

Convertible Securities. The trust's investment in fixed income securities may include bonds and preferred stocks that are convertible into the equity securities of the issuer or a related company. The trust will not invest more that 50% of its total in convertible securities. Depending upon the relationship of the conversion price to the market value of the underlying securities, convertible securities may trade more like equity securities than debt instruments. Consistent with its objective and other investment policies, the trust may also invest a portion of its assets in equity securities, including common stocks, depositary receipts, warrants, rights and other equity interests.

Loans. The trust may invest a portion of its assets in loan participations and other direct claims against a borrower. The trust considers corporate loans to be high yield debt instruments if the issuer has outstanding debt securities rated below investment grade or has no rated securities, and includes corporate loans in determining whether at least 80% of its assets are invested in high yield debt instruments. The corporate loans in which the trust invests primarily consist of direct obligations of a borrower and may include debtor in possession financings pursuant to Chapter 11 of the U.S. Bankruptcy Code, obligations of a borrower issued in connection with a restructuring pursuant to Chapter 11 of the U.S. Bankruptcy Code, leveraged buy-out loans, leveraged recapitalization loans, receivables purchase facilities, and privately placed notes. The trust may invest in a corporate loan at origination as a co-lender or by acquiring in the secondary market participations in, assignments of or novations of a corporate loan. By purchasing a participation, the trust acquires some or all of the interest of a bank or other lending institution in a loan to a corporate or government borrower. The participations typically will result in the trust having a contractual relationship only with the lender, not the borrower. The trust will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower. Many such loans are secured, although some may be unsecured. Such loans may be in default at the time of purchase. Loans that are fully secured offer the trust more protection than an unsecured loan in the event of non-payment of scheduled interest or principal. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower's obligation, or that the collateral can be liquidated. Direct debt instruments may involve a risk of loss in case of default or insolvency of the borrower and may offer less legal protection

17

to the trust in the event of fraud or misrepresentation. In addition, loan participations involve a risk of insolvency of the lending bank or other financial intermediary. The markets in loans are not regulated by federal securities laws or the Securities and Exchange Commission (SEC).

As in the case of other high yield investments, such corporate loans may be rated in the lower rating categories of the established rating services (Ba or lower by Moody's or BB or lower by Standard & Poor's), or may be unrated investments considered by Pioneer to be of comparable quality. As in the case of other high yield investments, such corporate loans can be expected to provide higher yields than lower yielding, higher rated fixed income securities, but may be subject to greater risk of loss of principal and income. There are, however, some significant differences between corporate loans and high yield bonds. Corporate loan obligations are frequently secured by pledges of liens and security interests in the assets of the borrower, and the holders of corporate loans are frequently the beneficiaries of debt service subordination provisions imposed on the borrower's bondholders. These arrangements are designed to give corporate loan investors preferential treatment over high yield investors in the event of a deterioration in the credit quality of the issuer. Even when these arrangements exist, however, there can be no assurance that the borrowers of the corporate loans will repay principal and/or pay interest in full. Corporate loans generally bear interest at rates set at a margin above a generally recognized base lending rate that may fluctuate on a day-to-day basis, in the case of the prime rate of a U.S. bank, or which may be adjusted on set dates, typically 30 days but generally not more than one year, in the case of the London Interbank Offered Rate. Consequently, the value of corporate loans held by the trust may be expected to fluctuate significantly less than the value of other fixed rate high yield instruments as a result of changes in the interest rate environment. On the other hand, the secondary dealer market for certain corporate loans may not be as well developed as the secondary dealer market for high yield bonds and, therefore, presents increased market risk relating to liquidity and pricing concerns.

Distressed Securities. The trust may invest up to 10% of its total assets in distressed securities, including corporate loans, which are the subject of bankruptcy proceedings or otherwise in default as to the repayment of principal and/or payment of interest at the time of acquisition by the trust or are rated in the lower rating categories (Ca or lower by Moody's or CC or lower by Standard & Poor's) or which are unrated investments considered by Pioneer to be of comparable quality. Investment in distressed securities is speculative and involves significant risk. Distressed securities frequently do not produce income while they are outstanding and may require the trust to bear certain extraordinary expenses in order to protect and recover its investment. Therefore, to the extent the trust seeks capital appreciation through investment in distressed securities, the trust's ability to achieve current income for its shareholders may be diminished. The trust also will be subject to significant uncertainty as to when and in what manner and for what value the obligations evidenced by the distressed securities will eventually be satisfied (e.g., through a liquidation of the obligor's assets, an exchange offer or plan of reorganization involving the distressed securities or a payment of some amount in satisfaction of the obligation). In addition, even if an exchange offer is made or a plan of reorganization is adopted with respect to distressed securities held by the trust, there can be no assurance that the securities or other assets received by the trust in connection with such exchange offer or plan of reorganization will not have a lower value or income potential than may have been anticipated when the investment was made. Moreover, any securities received by the trust upon completion of an exchange offer or plan of reorganization may be restricted as to resale. As a result of the trust's participation in negotiations with respect to any exchange offer or plan of reorganization with respect to an issuer of distressed securities, the trust may be restricted from disposing of such securities.

Preferred Shares. The trust may invest in preferred shares. Preferred shares are equity securities, but they have many characteristics of fixed income securities, such as a fixed dividend payment rate and/or a liquidity preference over the issuer's common shares. However, because preferred

18

shares are equity securities, they may be more susceptible to risks traditionally associated with equity investments than the trust's fixed income securities.

Foreign Securities. While the trust primarily invests in securities of U.S. issuers, the trust may invest up to 25% of its total assets in securities of corporate and governmental issuers located outside the United States, including debt and equity securities of corporate issuers and debt securities of government issuers in developed and emerging markets.

Illiquid Securities. The trust may invest in bonds, corporate loans, convertible securities, preferred stocks and other securities that lack a secondary trading market or are otherwise considered illiquid. Liquidity of a security relates to the ability to easily dispose of the security and the price to be obtained upon disposition of the security, which may be less than would be obtained for a comparable more liquid security. The trust may invest up to 50% of its total assets in investments that are not readily marketable, and it may also invest in securities that are subject to contractual restrictions on resale. Such investments may affect the trust's ability to realize the net asset value in the event of a voluntary or involuntary liquidation of its assets. See "Net Asset Value" for information with respect to the valuation of illiquid securities.

Structured Securities. The trust may invest in structured securities. The value of the principal and/or interest on such securities is determined by reference to changes in the value of specific currencies, interest rates, commodities, indices or other financial indicators (Reference) or the relative change in two or more References. The interest rate or the principal amount payable upon maturity or redemption may be increased or decreased depending upon changes in the Reference. The terms of the structured securities may provide in certain circumstances that no principal is due at maturity and, therefore, may result in a loss of the trust's investment. Changes in the interest rate or principal payable at maturity may be a multiple of the changes in the value of the Reference. Consequently, structured securities may entail a greater degree of market risk than other types of fixed income securities.

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

19

whole. Non-governmental mortgage-backed securities may offer higher yields than those issued by government entities but also may be subject to greater price changes than governmental issues.

Asset-Backed Securities. The trust may invest in asset-backed securities, which are securities that represent a participation in, or are secured by and payable from, a stream of payments generated by particular assets, most often a pool or pools of similar assets (e.g., trade receivables). The credit quality of these securities depends primarily upon the quality of the underlying assets and the level of credit support and/or enhancement provided.

The underlying assets (e.g., loans) are subject to prepayments which shorten the securities' weighted average maturity and may lower their return. If the credit support or enhancement is exhausted, losses or delays in payment may result if the required payments of principal and interest are not made. The value of these securities also may change because of changes in the market's perception of the creditworthiness of the servicing agent for the pool, the originator of the pool, or the financial institution or trust providing the credit support or enhancement.

REITs. REITs primarily invest in income producing real estate or real estate related loans or interests. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs are not taxed on income distributed to shareholders provided they comply with the applicable requirements of the Internal Revenue Code of 1986, as amended (the Internal Revenue Code). The trust will in some cases indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests in addition to the expenses paid by the trust. Debt securities issued by REITs are, for the most part, general and unsecured obligations and are subject to risks associated with REITs.

U.S. Government Securities. U.S. government securities in which the trust invests include debt obligations of varying maturities issued by the U.S. Treasury or issued or guaranteed by an agency or instrumentality of the U.S. government, including the Federal Housing Administration, Federal Financing Bank, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, Government National Mortgage Association (GNMA), General Services Administration, Central Bank for Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation (FHLMC), Federal National Mortgage Association (FNMA), Maritime Administration, Tennessee Valley Authority, District of Columbia Armory Board, Student Loan Marketing Association, Resolution Trust Corporation and various institutions that previously were or currently are part of the Farm Credit System (which has been undergoing reorganization since 1987). Some U.S. government securities, such as U.S. Treasury bills, Treasury notes and Treasury bonds, which differ only in their interest rates, maturities and times of issuance, are supported by the full faith and credit of the United States. Others are supported by: (i) the right of the issuer to borrow from the U.S. Treasury, such as securities of the Federal Home Loan Banks; (ii) the discretionary authority of the U.S. government to purchase the agency's obligations, such as securities of the FNMA; or (iii) only the credit of the issuer. No assurance can be given that the U.S. government will provide financial support in the future to U.S. government agencies, authorities or instrumentalities that are not supported by the full faith and credit of the United States. Securities guaranteed as to principal and interest by the U.S. government, its agencies, authorities or instrumentalities include: (i) securities for which the payment of principal and interest is backed by an irrevocable letter of credit issued by the U.S. government or any of its agencies, authorities or instrumentalities; and (ii) participations in loans made to non-U.S. governments or other entities that

20

are so guaranteed. The secondary market for certain of these participations is limited and, therefore, may be regarded as illiquid.

Zero Coupon Securities. The securities in which the trust invests may include zero coupon securities, which are debt obligations that are issued or purchased at a significant discount from face value. The discount approximates the total amount of interest the security will accrue and compound over the period until maturity or the particular interest payment date at a rate of interest reflecting the market rate of the security at the time of issuance. Zero coupon securities do not require the periodic payment of interest. These investments benefit the issuer by mitigating its need for cash to meet debt service, but generally require a higher rate of return to attract investors who are willing to defer receipt of cash. These investments may experience greater volatility in market value than securities that make regular payments of interest. The trust accrues income on these investments for tax and accounting purposes, which is distributable to shareholders and which, because no cash is received at the time of accrual, may require the liquidation of other portfolio securities to satisfy the trust's distribution obligations, in which case the trust will forgo the purchase of additional income producing assets with these funds. Zero coupon U.S. government securities include STRIPS and CUBES, which are issued by the U.S. Treasury as component parts of U.S. Treasury bonds and represent scheduled interest and principal payments on the bonds.

Investments in Equity Securities. Consistent with its objective, the trust may invest in equity securities. Equity securities, such as common stock, generally represent an ownership interest in a company. While equity securities have historically generated higher average returns than fixed income securities, equity securities have also experienced significantly more volatility in those returns. An adverse event, such as an unfavorable earnings report, may depress the value of a particular equity security held by the trust. Also, the price of equity securities, particularly common stocks, are sensitive to general movements in the stock market. A drop in the stock market may depress the price of equity securities held by the trust.

Other Investment Companies. The trust may invest in the securities of other investment companies to the extent that such investments are consistent with the trust's investment objective and policies and permissible under the 1940 Act. Under the 1940 Act, the trust may not acquire the securities of other domestic or non-U.S. investment companies if, as a result, (i) more than 10% of the trust's total assets would be invested in securities of other investment companies, (ii) such purchase would result in more than 3% of the total outstanding voting securities of any one investment company being held by the trust, or (iii) more than 5% of the trust's total assets would be invested in any one investment company. These limitations do not apply to the purchase of shares of any investment company in connection with a merger, consolidation, reorganization or acquisition of substantially all the assets of another investment company. The trust does not currently intend to invest in other investment companies for which Pioneer or any of its affiliates act as an investment adviser or distributor. However, Pioneer has applied for, and if granted would rely upon, an exemptive order from the SEC that would permit the trust to invest cash balances in money market funds managed by Pioneer.

The trust, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies' expenses, including advisory fees. These expenses are in addition to the direct expenses of the trust's own operations.

Defensive and Temporary Investments. When changing economic conditions and other factors cause the yield difference between lower rated and higher rated securities to narrow, the trust may purchase higher rated debt instruments if Pioneer believes that the risk of loss of income and principal may be reduced substantially with only a relatively small reduction in yield. In addition, under unusual

21

market or economic conditions or for temporary defensive purposes, the trust may invest up to 100% of its total assets in securities issued or guaranteed by the U.S. government or its instrumentalities or agencies, certificates of deposit, bankers' acceptances and other bank obligations, commercial paper rated in the highest category by a nationally recognized statistical rating organization or other fixed income securities deemed by Pioneer to be consistent with a defensive posture, or may hold cash. The yield on such securities may be lower than the yield on lower rated fixed income securities.

Strategic Transactions. The trust may, but is not required to, use various strategic transactions described below to earn income, facilitate portfolio management and mitigate risks. Such strategic transactions are generally accepted under modern portfolio management and are regularly used by many mutual funds and other institutional investors. Although Pioneer seeks to use the practices to further the trust's investment objective, no assurance can be given that these practices will achieve this result.

The trust may purchase and sell derivative instruments such as exchange-listed and over-the-counter put and call options on securities, financial futures, equity, fixed-income and interest rate indices, and other financial instruments, purchase and sell financial futures contracts and options thereon, enter into various interest rate transactions such as swaps, caps, floors or collars and enter into various currency transactions such as currency forward contracts, currency futures contracts, currency swaps or options on currency or currency futures or credit transactions and credit default swaps. The trust also may purchase derivative instruments that combine features of these instruments. Collectively, all of the above are referred to as "Strategic Transactions." The trust generally seeks to use Strategic Transactions as a portfolio management or hedging technique to seek to protect against possible adverse changes in the market value of securities held in or to be purchased for the trust's portfolio, protect the value of the trust's portfolio, facilitate the sale of certain securities for investment purposes, manage the effective interest rate exposure of the trust, protect against changes in currency exchange rates, manage the effective maturity or duration of the trust's portfolio, or establish positions in the derivatives markets as a temporary substitute for purchasing or selling particular securities. The trust may use Strategic Transactions to enhance potential gain, although no more than 5% of the trust's total assets will be committed to initial margin for Strategic Transactions for non-hedging purposes.

Strategic Transactions have risks, including the imperfect correlation between the value of such instruments and the underlying assets, the possible default of the other party to the transaction or illiquidity of the derivative instruments. Furthermore, the ability to successfully use Strategic Transactions depends on Pioneer's ability to predict pertinent market movements, which cannot be assured. Thus, the use of Strategic Transactions may result in losses greater than if they had not been used, may require the trust to sell or purchase portfolio securities at inopportune times or for prices other than current market values, may limit the amount of appreciation the trust can realize on an investment, or may cause the trust to hold a security that it might otherwise sell. The use of currency transactions can result in the trust incurring losses as a result of the imposition of exchange controls, suspension of settlements or the inability of the trust to deliver or receive a specified currency. Additionally, amounts paid by the trust as premiums and cash or other assets held in margin accounts with respect to Strategic Transactions are not otherwise available to the trust for investment purposes.

A more complete discussion of Strategic Transactions and their risks is contained in the statement of additional information.

Mortgage Dollar Rolls. The trust may enter into mortgage dollar roll transactions to earn additional income. In these transactions, the trust sells a U.S. agency mortgage-backed security and simultaneously agrees to repurchase 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

22

trust loses the right to receive interest and principal payments on the security it sold. However, the trust benefits from the interest earned on investing the proceeds of the sale and may receive a fee or a lower repurchase price. The benefits from these transactions depend upon Pioneer's ability to forecast mortgage prepayment patterns on different mortgage pools. The trust 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.

Repurchase Agreements. The trust may enter into repurchase agreements with broker-dealers, member banks of the Federal Reserve System and other financial institutions. Repurchase agreements are arrangements under which the trust purchases securities and the seller agrees to repurchase the securities within a specific time and at a specific price. The repurchase price is generally higher than the trust's purchase price, with the difference being income to the trust. Under the direction of the Board of Trustees, Pioneer reviews and monitors the creditworthiness of any institution which enters into a repurchase agreement with the trust. The counterparty's obligations under the repurchase agreement are collateralized with U.S. Treasury and/or agency obligations with a market value of not less than 100% of the obligations, valued daily. Collateral is held by the trust's custodian in a segregated, safekeeping account for the benefit of the trust. Repurchase agreements afford the trust an opportunity to earn income on temporarily available cash at low risk. In the event of commencement of bankruptcy or insolvency proceedings with respect to the seller of the security before repurchase of the security under a repurchase agreement, the trust may encounter delay and incur costs before being able to sell the security. Such a delay may involve loss of interest or a decline in price of the security. If the court characterizes the transaction as a loan and the trust has not perfected a security interest in the security, the trust may be required to return the security to the seller's estate and be treated as an unsecured creditor of the seller. As an unsecured creditor, the trust would be at risk of losing some or all of the principal and interest involved in the transaction.

Lending of Portfolio Securities. The trust may lend portfolio securities to registered broker-dealers or other institutional investors deemed by Pioneer to be of good standing under agreements which require that the loans be secured continuously by collateral in cash, cash equivalents or U.S. Treasury bills maintained on a current basis at an amount at least equal to the market value of the securities loaned. The trust continues to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned as well as the benefit of an increase and the detriment of any decrease in the market value of the securities loaned and would also receive compensation based on investment of the collateral. The trust would not, however, have the right to vote any securities having voting rights during the existence of the loan, but would call the loan in anticipation of an important vote to be taken among holders of the securities or of the giving or withholding of consent on a material matter affecting the investment.

As with other extensions of credit, there are risks of delay in recovery or even loss of rights in the collateral should the borrower of the securities fail financially. The trust will lend portfolio securities only to firms that have been approved in advance by the Board of Trustees, which will monitor the creditworthiness of any such firms. At no time would the value of the securities loaned exceed 33 1/3% of the value of the trust's total assets.

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

BENEFITS OF INVESTING IN THE TRUST

Investment in the trust offers the individual investor several potential benefits. In managing a portfolio of debt instruments, Pioneer provides professional management which includes the extensive credit analysis needed to invest in high yield bonds, corporate loans, distressed securities, foreign securities, convertible securities and preferred shares. The trust also relieves the investor of the burdensome administrative details involved in managing a portfolio of such investments. Additionally, Pioneer may seek to enhance the yield or capital appreciation of the trust's common shares by leveraging the trust's capital structure through the issuance of preferred shares or short-term debt securities or the borrowing of money. These benefits are at least partially offset by the expenses involved in running an investment company. Such expenses primarily consist of advisory fees and operational costs. The use of leverage also involves certain expenses and risk considerations. See "Risk Factors--Leverage" and "Leverage."

PIONEER'S INVESTMENT APPROACH

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

Pioneer's analysis of issuers may include, among other things, historic and current financial conditions, current and anticipated cash flow and borrowing requirements, value of assets in relation to historical costs, strength of management, responsiveness to business conditions, credit standing, and current and anticipated results of operations. While Pioneer considers as one factor in its credit analysis the ratings assigned by the rating services, Pioneer performs its own independent credit analysis of issuers and, consequently, the trust may invest, without limit, in unrated securities. As a result, the trust's ability to achieve its investment objective may depend to a greater extent on Pioneer's own credit analysis than investment companies which invest in higher rated securities.

In making these portfolio decisions, Pioneer relies on the knowledge, experience and judgment of its staff who have access to a wide variety of research. The trust may continue to hold securities that are downgraded after the trust purchases them and will sell such securities only if, in Pioneer's judgment, it is advantageous to sell such securities.

LEVERAGE

The trust may issue preferred shares or borrow or issue short-term debt securities to increase its assets available for investment. The trust is authorized to issue preferred shares or issue debt obligations to the maximum extent permitted by the 1940 Act. The trust currently anticipates that it will issue, as soon as practicable after the closing of this offering, preferred shares with an aggregate liquidation preference of up to 25% of the trust's total assets, but will be permitted to incur leverage in an amount up to 33 1/3% of the trust's total assets. The trust generally will not issue preferred shares or borrow

24

unless Pioneer expects that the trust will achieve a greater return on such borrowed funds than the additional costs the trust incurs as a result of such borrowing. The trust also may borrow money as a temporary measure for extraordinary or emergency purposes, including the payment of dividends and the settlement of securities transactions which otherwise might require untimely dispositions of the trust's holdings. When the trust leverages its assets, the fees paid to Pioneer for investment advisory and management services will be higher than if the trust did not borrow because Pioneer's fees are calculated based on the trust's total assets including the proceeds of the issuance of preferred shares or any outstanding borrowings. Consequently, the trust and Pioneer may have differing interests in determining whether to leverage the trust's assets. The Board of Trustees will monitor this potential conflict.

The trust's use of leverage is premised upon the expectation that the trust's preferred share dividends or borrowing cost will be lower than the return the trust achieves on its investments with the proceeds of the issuance of preferred shares or borrowing. Such difference in return may result from the trust's higher credit rating or the short-term nature of its borrowing compared to the long-term nature of its investments. Since the total assets of the trust (including the assets obtained from leverage) will be invested in the higher yielding portfolio investments or portfolio investments with the potential for capital appreciation, the holders of common shares will be the beneficiaries of the incremental return. Should the differential between the underlying assets and cost of leverage narrow, the incremental return "pick up" will be reduced. Furthermore, if long-term rates rise or the trust otherwise incurs losses on its investments, the trust's net asset value attributable to its common shares will reflect the decline in the value of portfolio holdings resulting therefrom.

Leverage creates risks which may adversely affect the return for the holders of common shares, including:

- the likelihood of greater volatility of net asset value and market price of common shares;

- fluctuations in the dividend rates on any preferred shares or in interest rates on borrowings and short-term debt;

- increased operating costs, which may reduce the trust's total return; and

- the potential for a decline in the value of an investment acquired with borrowed funds, while the trust's obligations under such borrowing remains fixed.

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the trust's return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage or if the trust incurs capital losses, the return of the trust will be less than if leverage had not been used, and therefore the amount available for distribution to shareholders as dividends and other distributions will be reduced or potentially eliminated. Pioneer may determine to maintain the trust's leveraged position if it expects that the long-term benefits to the trust's shareholders of maintaining the leveraged position will outweigh the current reduced return. Capital raised through the issuance of preferred shares or borrowing will be subject to dividend payments or interest costs that may or may not exceed the income and appreciation on the assets purchased. The issuance of additional classes of preferred shares involves offering expenses and other costs and may limit the trust's freedom to pay dividends on common shares or to engage in other activities. The trust also may be required to maintain minimum average balances in connection with borrowings or to pay a commitment or other fee to maintain a line of credit; either of these requirements will increase the cost of borrowing over the stated interest rate.

25

The trust may be subject to certain restrictions on investments imposed by guidelines of one or more nationally recognized rating organizations which may issue ratings for the preferred shares or short-term debt instruments issued by the trust. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act. Certain types of borrowings may result in the trust being subject to covenants in credit agreements, including those relating to asset coverage, borrowing base and portfolio composition requirements and additional covenants that may affect the trust's ability to pay dividends and distributions on common shares in certain instances. The trust may also be required to pledge its assets to the lenders in connection with certain types of borrowing. Pioneer does not anticipate that these covenants or restrictions will adversely affect its ability to manage the trust's portfolio in accordance with the trust's investment objective and policies. Due to these covenants or restrictions, the trust may be forced to liquidate investments at times and at prices that are not favorable to the trust, or the trust may be forced to forgo investments that Pioneer otherwise views as favorable.

Under the 1940 Act, the trust is not permitted to issue preferred shares unless immediately after such issuance the net asset value of the trust's portfolio is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the value of the trust's total assets). In addition, the trust is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such declaration, the net asset value of the trust's portfolio (determined after deducting the amount of such dividend or distribution) is at least 200% of such liquidation value. In the event preferred shares are issued, the trust intends, to the extent possible, to purchase or redeem preferred shares from time to time to maintain coverage of any preferred shares of at least 200%. Under the 1940 Act, the trust is not permitted to incur indebtedness unless immediately after such borrowing the trust has an asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the value of the trust's total assets). Additionally, under the 1940 Act, the trust may not declare any dividend or other distribution upon any class of its shares, or purchase any such shares, unless the aggregate indebtedness of the trust has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be.

If and to the extent that the trust employs leverage will depend on many factors, the most important of which are investment outlook, market conditions and interest rates. Successful use of a leveraging strategy depends on Pioneer's ability to predict correctly interest rates and market movements. There is no assurance that a leveraging strategy will be successful during any period in which it is employed. None of the other investment companies managed by Pioneer use leverage to a material extent or as part of a systematic investment program.

Assuming the trust issues preferred shares with a liquidation preference equal to approximately 25% of the trust's total assets and an annual dividend rate of 2.30% of such liquidation preference (which rate is approximately the rate which Pioneer expects the trust to pay), based on market rates as of the date of this prospectus, the trust would need to achieve an annual return on its total assets of 1.295% in order to cover such dividend payments on the preferred shares.

The following table illustrates the hypothetical effect on the return to a holder of the trust's common shares of the leverage obtained by issuing preferred shares with a liquidation value equal to 25% of the trust's total assets, assuming hypothetical annual returns of the trust's portfolio of minus 10% to plus 10%. As the table shows, leverage generally increases the return to shareholders when portfolio return is positive and greater than the cost of leverage and decreases the return when the

26

portfolio return is negative or less than the cost of leverage. The figures appearing in the table are hypothetical and actual returns may be greater or less than those appearing in the table.

Assumed portfolio return (net of expenses).....  (10.00)%  (5.00)%   0.00%   5.00%   10.00%
Corresponding common share return..............  (14.10)%  (7.43)%  (0.76)%  5.90%   12.56%

Until the trust issues preferred shares or borrows, the trust's common shares will not be leveraged, and the risks and special considerations related to leverage described in this prospectus will not apply. Such leveraging of the common shares cannot be fully achieved until the proceeds resulting from the use of leverage have been invested in longer term debt instruments in accordance with the trust's investment objective and policies.

RISK FACTORS

General. The trust is a diversified, closed-end management investment company designed primarily as a long-term investment and not as a trading tool. Because the trust invests in high yield securities, an investment in the trust's common shares may be speculative in that it involves a high degree of risk. The trust should not constitute a complete investment program. Due to the uncertainty in all investments, there can be no assurance that the trust will achieve its investment objective.

No Operating History. The trust is a newly organized closed-end management investment company and has no operating history or history of public trading.

High Yield Debt Securities. Investment in high yield securities involves substantial risk of loss. Below investment grade debt securities or comparable unrated securities are commonly referred to as "junk bonds" and are considered predominantly speculative with respect to the issuer's ability to pay interest and principal and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for high yield securities tend to be very volatile, and these securities are less liquid than investment grade debt securities. For these reasons, your investment in the trust is subject to the following specific risks:

- Increased price sensitivity to changing interest rates and to a deteriorating economic environment;

- Greater risk of loss due to default or declining credit quality;

- Adverse company specific events are more likely to render the issuer unable to make interest and/or principal payments; and

- If a negative perception of the high yield market develops, the price and liquidity of high yield securities may be depressed. This negative perception could last for a significant period of time.

Debt securities rated below investment grade are speculative with respect to the capacity to pay interest and repay principal in accordance with the terms of such securities. A rating of C from Moody's means that the issue so rated can be regarded as having extremely poor prospects of ever attaining any real investment standing. Standard & Poor's assigns a rating of C to issues that are currently highly vulnerable to nonpayment, and the C rating may be used to cover a situation where a bankruptcy petition has been filed or similar action taken, but payments on the obligation are being continued (a C rating is also assigned to a preferred stock issue in arrears on dividends or sinking fund payments, but that is currently paying). See the statement of additional information for a description of Moody's and Standard & Poor's ratings.

27

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a high yield issuer to make principal payments and interest payments than an investment grade issuer. The principal amount of high yield securities outstanding has proliferated in the past decade as an increasing number of issuers have used high yield securities for corporate financing. An economic downturn could severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. The percentage of defaults on high yield debt securities as reported by Moody's were 5.5% and 5.7% in 1999 and 2000, and increased to 10.2% in 2001. If the national economy enters into a deeper recessionary phase during 2002 or interest rates rise sharply, the number of defaults by high yield issuers is likely to increase. Similarly, down-turns in profitability in specific industries could adversely affect the ability of high yield issuers in those industries to meet their obligations. The market values of lower quality debt securities tend to reflect individual developments of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse effect on the trust's net asset value and the market value of its common shares. In addition, the trust may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the trust may be required to foreclose on an issuer's assets and take possession of its property or operations. In such circumstances, the trust would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for high yield securities may not be as liquid as the secondary market for more highly rated securities, a factor which may have an adverse effect on the trust's ability to dispose of a particular security when necessary to meet its liquidity needs. There are fewer dealers in the market for high yield securities than investment grade obligations. The prices quoted by different dealers may vary significantly and the spread between the bid and asked price is generally much larger than for higher quality instruments. Under adverse market or economic conditions, the secondary market for high yield securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the trust could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the trust's net asset value.

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

If the trust invests in high yield securities that are rated C or below, the trust will incur significant risk in addition to the risks associated with investments in high yield securities and corporate loans. Distressed securities frequently do not produce income while they are outstanding. The trust may purchase distressed securities that are in default or the issuers of which are in bankruptcy. The trust may be required to bear certain extraordinary expenses in order to protect and recover its investment.

Leverage. The trust may issue preferred shares, borrow money or issue debt securities with a liquidation preference or principal amount up to the maximum extent permitted by the 1940 Act.

28

Leverage creates risks which may adversely affect the return for the holders of common shares, including:

- the likelihood of greater volatility of net asset value and market price of common shares;

- fluctuations in the dividend rates on any preferred shares or in interest rates on borrowings and short-term debt;

- increased operating costs, which may reduce the trust's total return; and

- the potential for a decline in the value of an investment acquired with borrowed funds, while the trust's obligations under such borrowing remain fixed.

To the extent the income or capital appreciation derived from securities purchased with funds received from leverage exceeds the cost of leverage, the trust's return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such funds is not sufficient to cover the cost of leverage or if the trust incurs capital losses, the return of the trust will be less than if leverage had not been used, and therefore the amount available for distribution to shareholders as dividends and other distributions will be reduced or potentially eliminated.

Certain types of borrowings may result in the trust being subject to covenants in credit agreements, including those relating to asset coverage, borrowing base and portfolio composition requirements and additional covenants that may affect the trust's ability to pay dividends and distributions on common shares in certain instances. The trust may also be required to pledge its assets to the lenders in connection with certain types of borrowing. The trust may be subject to certain restrictions on investments imposed by guidelines of one or more nationally recognized rating organizations which may issue ratings for the preferred shares or short-term debt instruments issued by the trust. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed by the 1940 Act.

Since Pioneer's fee is a percentage of the trust's total assets, Pioneer's fee will be higher if the trust is leveraged and Pioneer will have an incentive to be more aggressive and leverage the trust.

Interest Rate Risk. Fixed income securities, including high yield securities, are subject to certain common risks, including:

- If interest rates go up, the value of debt securities in the trust's portfolio generally will decline;

- During periods of declining interest rates, the issuer of a security may exercise its option to prepay principal earlier than scheduled, forcing the trust to reinvest in lower yielding securities. This is known as call or prepayment risk. Debt securities frequently have call features that allow the issuer to repurchase the security prior to its stated maturity. An issuer may redeem an obligation if the issuer can refinance the debt at a lower cost due to declining interest rates or an improvement in the credit standing of the issuer;

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

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

29

Convertible Securities. The trust may invest up to 50% of its total assets in convertible securities. Convertible fixed income 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 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.

Corporate Loans. The trust may acquire interests in loans made by banks or other financial institutions to corporate issuers or participation interests in such loans. By purchasing a participation interest in a loan, the trust acquires some or all of the interest of a bank or other lending institution in a loan to a corporate or government borrower. The participations typically will result in the trust having a contractual relationship only with the lender, not the borrower. The trust will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the participation and only upon receipt by the lender of the payments from the borrower.

Unlike most other high yield securities, corporate loan obligations are frequently secured by security interests in the assets of the borrower and the holders of corporate loans are frequently the beneficiaries of debt service subordination provisions imposed on the borrower's bondholders. If the trust only acquires a participation in the loan made by a third party, the trust may not be able to control the exercise of any remedies that the lender would have under the corporate loan. These arrangements are designed to give corporate loan investors preferential treatment over high yield investors in the event of a deterioration in the credit quality of the issuer. Even when these arrangements exist, however, there can be no assurance that the principal and interest owed on the corporate loan will be repaid in full. Corporate loans generally bear interest at rates set at a margin above a generally recognized base lending rate that may fluctuate on a day-to-day basis, in the case of the prime rate of a U.S. bank, or which may be adjusted on set dates, typically 30 days but generally not more than one year, in the case of the London Interbank Offered Rate. Consequently, the value of corporate loans held by the trust may be expected to fluctuate significantly less than the value of other fixed rate high yield instruments as a result of changes in the interest rate environment. On the other hand, the secondary dealer market for certain corporate loans may not be as well developed as the secondary dealer market for high yield bonds and, therefore, presents increased market risk relating to liquidity and pricing concerns.

Mortgage- and Asset-Backed Securities and Structured Securities. To the extent the trust invests significantly in asset-backed and mortgage-related securities, its exposure to prepayment and extension risks may be greater than if it invested in other fixed income securities. Certain debt instruments may only pay principal at maturity or may only represent the right to receive payments of principal or payments of interest on underlying pools of mortgage or government securities, but not both. The value of these types of instruments may change more drastically than debt securities that pay both principal and interest during periods of changing interest rates. Principal only mortgage-backed securities generally increase in value if interest rates decline, but are also subject to the risk of prepayment. Interest only instruments generally increase in value in a rising interest rate environment when fewer of the underlying mortgages are prepaid. The value of interest only instruments may decline significantly or these instruments may become worthless in the event that the underlying mortgage pool experiences substantial and unanticipated prepayments.

30

The trust may invest in mortgage derivatives and structured securities. Because these securities have imbedded leverage features, small changes in interest or prepayment rates may cause large and sudden price movements. Mortgage derivatives can also become illiquid and hard to value in declining markets.

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

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

REITs may have limited financial resources and may trade less frequently and in a more limited volume than larger company securities.

Illiquid Investments. The trust may invest up to 50% of its total assets in illiquid securities. Illiquid securities may be difficult to dispose of at a fair price at the times when the trust believes it is desirable to do so. The market price of illiquid securities generally is more volatile than that of more liquid securities, which may adversely affect the price that the trust pays for or recovers upon the sale of illiquid securities. Illiquid securities are also more difficult to value and Pioneer's judgement may play a greater role in the valuation process. Investment of the trust's assets in illiquid securities may restrict the trust's ability to take advantage of market opportunities. The risks associated with illiquid securities may be particularly acute in situations in which the trust's operations require cash and could result in the trust borrowing to meet its short-term needs or incurring losses on the sale of illiquid securities.

Foreign Securities. Investments in non-U.S. issuers may involve unique risks compared to investing in securities of U.S. issuers. These risks are more pronounced to the extent that the trust invests a significant portion of its non-U.S. investments in one region or in the securities of emerging market issuers. These risks may include:

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

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

- Adverse effect of currency exchange rates or controls on the value of the trust's investments

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

31

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

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

There may be less publicly available information about non-U.S. markets and issuers than is available with respect to U.S. securities and issuers. Non-U.S. companies generally are not subject to accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to U.S. companies. The trading markets for most non-U.S. securities are generally less liquid and subject to greater price volatility than the markets for comparable securities in the U.S. The markets for securities in certain emerging markets are in the earliest stages of their development. Even the markets for relatively widely traded securities in certain non-U.S. markets, including emerging market countries, may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the U.S. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity.

Economies and social and political climate in individual countries may differ unfavorably from the U.S. Non-U.S. economies may have less favorable rates of growth of gross domestic product, rates of inflation, currency valuation, capital reinvestment, resource self-sufficiency and balance of payments positions. Many countries have experienced substantial, and in some cases extremely high, rates of inflation for many years. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, very negative effects on the economies and securities markets of certain emerging countries. Unanticipated political or social developments may also affect the values of the trust's investments and the availability to the trust of additional investments in such countries.

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

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

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

32

commitments to lend funds to the sovereign debtor, which may further impair such debtor's ability or willingness to service its debts.

Market Price of Shares. Shares of closed-end funds frequently trade at a prices lower than their net asset value. This is commonly referred to as "trading at a discount." This characteristic of shares of closed-end funds is a risk separate and distinct from the risk that the trust's net asset value may decrease. Investors who sell their shares within a relatively short period after completion of the public offering are likely to be exposed to this risk. Accordingly, the trust is designed primarily for long-term investors and should not be considered a vehicle for trading purposes. Net asset value will be reduced following the offering by the underwriting discount and the amount of offering expenses paid by the trust.

Whether investors will realize a gain or loss upon the sale of the trust's common shares will depend upon whether the market value of the shares at the time of sale is above or below the price the investor paid, taking into account transaction costs, for the shares and is not directly dependent upon the trust's net asset value. Because the market value of the trust's shares will be determined by factors such as the relative demand for and supply of the shares in the market, general market conditions and other factors beyond the control of the trust, the trust cannot predict whether its common shares will trade at, below or above net asset value, or below or above the initial offering price for the shares.

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

Anti-takeover Provisions. The trust's Agreement and Declaration of Trust and by-laws include provisions that could limit the ability of other entities or persons to acquire control of the trust or to change the composition of its Board of Trustees. Such provisions could limit the ability of shareholders to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the trust. These provisions include staggered terms of office for the Trustees, advance notice requirements for shareholder proposals, and super-majority voting requirements for certain transactions with affiliates, open-ending the trust or a merger, liquidation, asset sales and similar transactions.

Recent Events. The terrorist attacks in the United States on September 11, 2001 had a disruptive effect on the securities markets. The trust does not know how long the securities markets will continue to be affected by these events and cannot predict the effects of similar events in the future on the U.S. economy. High yield debt instruments tend to be more volatile than higher rated fixed income securities so that these events and any actions resulting from them may have a greater impact on the prices and volatility of high yield debt instruments than on higher rated fixed income securities.

MANAGEMENT OF THE TRUST

TRUSTEES AND OFFICERS

The trust's Board of Trustees provides broad supervision over the affairs of the trust. The officers of the trust are responsible for the trust's operations. The Trustees and officers of the trust, together with their principal occupations during the past five years, are listed in the statement of additional

33

information. Each of the Trustees serves as a Trustee of each of the 60 U.S. registered investment portfolios for which Pioneer serves as investment adviser.

INVESTMENT ADVISER

The trust has contracted with Pioneer to act as its investment adviser. Pioneer is an indirect, majority owned subsidiary of UniCredito. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2001, assets under management were approximately $99 billion worldwide, including over $19 billion in assets under management by Pioneer. Certain Trustees or officers of the trust are also directors and/or officers of certain of UniCredito's subsidiaries.

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

COMPENSATION AND EXPENSES

Under the management contract, the trust will pay to Pioneer monthly, as compensation for the services rendered and expenses paid by it, a fee equal on an annual basis to 0.60% of the trust's average weekly managed assets. Because the fee paid to Pioneer is determined on the basis of the trust's managed assets, Pioneer's interest in determining whether to leverage the trust may differ from the interests of the trust.

The trust's average weekly managed assets are determined for the purpose of calculating the management fee by taking the average of all the weekly determinations of total assets during a given calendar month. The fees are payable for each calendar month as soon as practicable after the end of that month.

Under the terms of its management contract with the trust, Pioneer pays all the operating expenses, including executive salaries and the rental of office space, relating to its services for the trust, with the exception of the following, which are to be paid by the trust: (a) charges and expenses for fund accounting, pricing and appraisal services and related overhead, including, to the extent such services are performed by personnel of Pioneer or its affiliates, office space and facilities and personnel compensation, training and benefits; (b) the charges and expenses of auditors; (c) the charges and expenses of any administrator, custodian, transfer agent, plan agent, dividend disbursing agent and registrar appointed by the trust; (d) issue and transfer taxes chargeable to the trust in connection with securities transactions to which the trust is a party; (e) insurance premiums, interest charges, dues and fees for membership in trade associations and all taxes and corporate fees payable by the trust to federal, state or other governmental agencies; (f) fees and expenses involved in registering and maintaining registrations of the trust and/or its shares with federal regulatory agencies, state or blue sky securities agencies and foreign jurisdictions, including the preparation of prospectuses and statements of additional information for filing with such regulatory authorities; (g) all expenses of shareholders' and Trustees' meetings and of preparing, printing and distributing prospectuses, notices, proxy statements and all reports to shareholders and to governmental agencies; (h) charges and expenses of legal counsel to the trust and the Trustees; (i) compensation of those Trustees of the trust who are not affiliated with

34

or interested persons of Pioneer or the trust (other than as Trustees); (j) the cost of preparing and printing share certificates; (k) interest on borrowed money, if any; and (l) the fees and other expenses of listing the trust's shares on the New York Stock Exchange or any other national stock exchange. In addition, the trust will pay all brokers' and underwriting commissions chargeable to the trust in connection with securities transactions to which the trust is a party.

The trust has also entered into an administration agreement with Pioneer, pursuant to which Pioneer provides certain administrative and accounting services. Pioneer is reimbursed by the trust for Pioneer's costs in providing such services, except for the fees of any sub-administrators retained by Pioneer, which fees are paid by Pioneer. Pioneer has retained Princeton Administrators L.P., an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, to provide certain administrative services to the trust on its behalf. Pioneer will pay Princeton Administrators L.P. a monthly fee equal at an annual rate to 0.10% of the average weekly value of the trust's managed assets, subject to a minimum monthly fee of $10,000.

PORTFOLIO MANAGER

Day-to-day management of the trust's portfolio is the responsibility of a team of fixed income portfolio managers led by Kenneth J. Taubes. The team manages other Pioneer mutual funds investing primarily in fixed income securities. Mr. Taubes is responsible for overseeing the U.S. and global fixed income team. He joined Pioneer as a senior vice president in September 1998 and has been an investment professional since 1982. Prior to joining Pioneer, Mr. Taubes had served since 1991 as a senior vice president and senior portfolio manager for several Putnam Investments institutional accounts and mutual funds. The team may draw upon the research and investment management expertise of Pioneer's affiliate, Pioneer Investment Management Limited.

John A. Carey, the head of portfolio management and an executive vice president of Pioneer, supervises Mr. Taubes and his team. Mr. Carey joined Pioneer as an analyst and has been an investment professional since 1979.

DIVIDENDS AND DISTRIBUTIONS; AUTOMATIC DIVIDEND REINVESTMENT PLAN

DIVIDENDS AND DISTRIBUTIONS

The trust intends to distribute dividends of all or a portion of its net investment income monthly to holders of common shares. It is expected that the trust will commence paying dividends to holders of common shares within approximately 90 days of the date of this prospectus. Dividends and distributions may be payable in cash or common shares, with the option to receive cash in lieu of the shares. The trust may at times in its discretion pay out less than the entire amount of net investment income earned in any particular period and may at times pay out such accumulated undistributed income in addition to net investment income earned in other periods in order to permit the trust to maintain a more stable level of distributions. As a result, the dividend paid by the trust to holders of common shares for any particular period may be more or less than the amount of net investment income earned by the trust during such period. The trust is not required to maintain a stable level of distributions to shareholders. For federal tax purposes, the trust is required to distribute substantially all of its net investment income for each year. All net realized capital gains, if any, will be distributed to the trust's shareholders at least annually.

Under the 1940 Act, the trust is not permitted to incur indebtedness unless immediately after such incurrence the trust has an asset coverage of at least 300% of the aggregate outstanding principal

35

balance of indebtedness. Additionally, under the 1940 Act, the trust may not declare any dividend or other distribution upon any class of its capital shares, or purchase any such capital shares, unless the aggregate indebtedness of the trust has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be.

While any preferred shares are outstanding, the trust may not declare any cash dividend or other distribution on its common shares, unless at the time of such declaration, (1) all accumulated preferred dividends have been paid and (2) the net asset value of the trust's portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of the liquidation value of the outstanding preferred shares (expected to be equal to the original purchase price per share plus any accumulated and unpaid dividends thereon).

In addition to the limitations imposed by the 1940 Act described above, certain lenders may impose additional restrictions on the payment of dividends or distributions on the common shares in the event of a default on the trust's borrowings. If the trust's ability to make distributions on its common shares is limited, such limitation could under certain circumstances impair the ability of the trust to maintain its qualification for taxation as a regulated investment company, which would have adverse tax consequences for shareholders. See "Leverage" and "U.S. Federal Income Tax Matters."

See "Automatic Dividend Reinvestment Plan" for information concerning the manner in which dividends and distributions to common shareholders may be automatically reinvested in common shares. Dividends and distributions may be taxable to shareholders whether they are reinvested in shares of the trust or received in cash.

The yield on the trust's common shares will vary from period to period depending on factors including, but not limited to, market conditions, the timing of the trust's investment in portfolio securities, the securities comprising the trust's portfolio, changes in interest rates including changes in the relationship between short-term rates and long-term rates, the amount and timing of the use of borrowings and other leverage by the trust, the effects of leverage on the common shares discussed above under "Leverage," the timing of the investment of leverage proceeds in portfolio securities, the trust's net assets and its operating expenses. Consequently, the trust cannot guarantee any particular yield on its shares and the yield for any given period is not an indication or representation of future yields on the trust's shares.

AUTOMATIC DIVIDEND REINVESTMENT PLAN

Pursuant to the trust's Automatic Dividend Reinvestment Plan (Plan), unless a shareholder is ineligible or elects otherwise, all dividend and capital gains distributions are automatically reinvested by Mellon Bank, N.A. (Mellon), as agent for shareholders in administering the Plan (Plan Agent), in additional common shares of the trust. In the event a dividend or capital gains distribution is declared in shares with the option to take cash and the shares are trading at a "market discount," as described below, the Plan provides that its distribution will be taken in cash and reinvested in accordance with the Plan. Shareholders who are ineligible or who elect not to participate in the Plan will receive all dividends and distributions payable in cash paid by check mailed directly to the shareholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Mellon, as dividend paying agent. Such shareholders may elect not to participate in the Plan and to receive all distributions of dividends and capital gains in cash by sending written instructions to Mellon, as dividend paying agent, at the address set forth below. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by written notice if received by the Plan

36

Agent not less than ten days prior to any dividend record date; otherwise, such termination will be effective with respect to any subsequently declared dividend or capital gains distribution.

Whenever the trust declares an ordinary income dividend or a capital gain dividend (collectively referred to as "dividends") payable either in shares or in cash, non-participants in the Plan will receive cash, and participants in the Plan will receive the equivalent in shares of common shares. The shares are acquired by the Plan Agent for the participant's account, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized common shares from the trust ("newly issued shares") or (ii) by purchase of outstanding common shares on the open market (open-market purchases) on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend or distribution, the net asset value per share of the common shares is equal to or less than the market price per common share plus estimated brokerage commissions (such condition being referred to herein as "market premium"), the Plan Agent will invest the amount of such dividend or distribution in newly issued shares on behalf of the participant. The number of newly issued common shares to be credited to the participant's account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance may not exceed 5%. If on the dividend payment date the net asset value per share is greater than the market value or premium (such condition being referred to herein as "market discount"), the Plan Agent will invest the dividend amount in shares acquired on behalf of the participant in open-market purchases. Prior to the time common shares commence trading on the New York Stock Exchange, participants in the Plan will receive any dividends in newly issued shares.

In the event of a market discount on the payment date for any dividend or distribution, the Plan Agent has until the last business day before the next date on which the shares trade on an "ex-dividend" basis or in no event more than 30 days after the dividend payment date (last purchase date) to invest the dividend amount in shares acquired in open-market purchases. It is contemplated that the trust will pay monthly income dividends. Therefore, the period during which open-market purchases can be made will exist only from the payment date on the dividend through the date before the next ex-dividend date, which typically will be approximately ten days. If, before the Plan Agent has completed its open-market purchases, the market price of a common share exceeds the net asset value per share, the average per share purchase price paid by the Plan Agent may exceed the net asset value of the trust's shares, resulting in the acquisition of fewer shares than if the dividend had been paid in newly issued shares on the dividend payment date. Because of the foregoing difficulty with respect to open- market purchases, the Plan provides that if the Plan Agent is unable to invest the full dividend amount in open-market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent will cease making open-market purchases and will invest the uninvested portion of the dividend amount in newly issued shares at the close of business on the last purchase date.

The Plan Agent maintains all shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the account, including information needed by shareholders for tax records. Dividend reinvestment is confirmed quarterly. Shares in the account of each Plan participant will be held by the Plan Agent in non-certificated form in the name of the participant, and each shareholder's proxy will include those shares purchased or received pursuant to the Plan. The Plan Agent will forward all proxy solicitation materials to participants and vote proxies for shares held pursuant to the Plan in accordance with the instructions of the participants.

In the case of shareholders such as banks, brokers or nominees which hold shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares

37

certified from time to time by the record shareholders as representing the total amount registered in the record shareholder's name and held for the account of beneficial owners who are to participate in the Plan.

There will be no brokerage charges with respect to shares issued directly by the trust as a result of dividends or capital gains distributions payable either in shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent's open-market purchases in connection with the reinvestment of dividends.

The automatic reinvestment of dividends and distributions will not relieve participants of any federal, state or local income tax that may be payable (or required to be withheld) on such dividends. See "U.S. Federal Income Tax Matters."

Shareholders participating in the Plan may receive benefits not available to shareholders not participating in the Plan. If the market price plus commissions of the trust's shares is higher than the net asset value, participants in the Plan will receive shares of the trust at less than they could otherwise purchase them and will have shares with a cash value greater than the value of any cash distribution they would have received on their shares. If the market price plus commissions is below the net asset value, participants receive distributions of shares with a net asset value greater than the value of any cash distribution they would have received on their shares. However, there may be insufficient shares available in the market to make distributions in shares at prices below the net asset value. Also, since the trust does not redeem its shares, the price on resale may be more or less than the net asset value.

Experience under the Plan may indicate that changes are desirable. Accordingly, the trust reserves the right to amend or terminate the Plan. There is no direct service charge to participants in the Plan; however, the trust reserves the right to amend the Plan to include a service charge payable by the participants.

All correspondence concerning the Plan should be directed to the Plan Agent at Mellon Investor Services, P.O. Box 3338, South Hackensack, New Jersey 07606-1938.

CLOSED-END FUND STRUCTURE

The trust is a newly organized, diversified, closed-end management investment company (commonly referred to as a closed-end fund). Closed-end funds differ from open-end funds (which are generally referred to as mutual funds) in that closed-end funds generally list their shares for trading on a stock exchange and do not redeem their shares at the request of the shareholder. This means that if you wish to sell your shares of a closed-end fund you must trade them on the market like any other stock at the prevailing market price at that time. In a mutual fund, if the shareholder wishes to sell shares of the fund, the mutual fund will redeem or buy back the shares at "net asset value." Also, mutual funds generally offer new shares on a continuous basis to new investors, and closed-end funds generally do not. The continuous inflows and outflows of assets in a mutual fund can make it difficult to manage the fund's investments. By comparison, closed-end funds are generally able to stay more fully invested in securities that are consistent with their investment objectives and also have greater flexibility to make certain types of investments and to use certain investment strategies, such as financial leverage and investments in illiquid securities.

Shares of closed-end funds frequently trade at a discount to their net asset value. Common shares of closed-end investment companies like the trust that invest predominantly in high yield securities have during some periods traded at prices higher than their net asset value (at a "premium")

38

and during other periods traded at prices lower than their net asset value (at a "discount"). This is in part because the market price reflects the dividend yield on the common shares. When the yield on the net asset value per share is higher than yields generally available in the market for comparable securities, the market price will tend to reflect this by trading higher than the net asset value per share to adjust the yield to a comparable market rate. To the extent the common shares do trade at a discount, the trust's Board of Trustees may from time to time engage in open market repurchases or tender offers for shares after balancing the benefit to shareholders of the increase in the net asset value per share resulting from such purchases against the decrease in the assets of the trust and potential increase in the expense ratio of expenses to assets of the trust and consequent reduction in yield. The Board of Trustees believes that in addition to the beneficial effects described above, any such purchases or tender offers may result in the temporary narrowing of any discount but will not have any long-term effect on the level of any discount.

U.S. FEDERAL INCOME TAX MATTERS

The following is a summary discussion of certain U.S. federal income tax consequences that may be relevant to a shareholder of acquiring, holding and disposing of common shares of the trust. This discussion only addresses U.S. federal income tax consequences to U.S. shareholders who hold their shares as capital assets and does not address all of the U.S. federal income tax consequences that may be relevant to particular shareholders in light of their individual circumstances. This discussion also does not address the tax consequences to shareholders who are subject to special rules, including, without limitation, financial institutions, insurance companies, dealers in securities or foreign currencies, foreign holders, persons who hold their shares as or in a hedge against currency risk, a constructive sale, or conversion transaction, holders who are subject to the alternative minimum tax, or tax-exempt or tax-deferred plans, accounts, or entities. In addition, the discussion does not address any state, local, or foreign tax consequences, and it does not address any federal tax consequences other than U.S. federal income tax consequences. The discussion reflects applicable tax laws of the United States as of the date of this prospectus, which tax laws may be changed or subject to new interpretations by the courts or the Internal Revenue Service (IRS) retroactively or prospectively. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the trust and its shareholders, and the discussion set forth herein does not constitute tax advice. Investors are urged to consult their own tax advisers to determine the specific tax consequences to them of investing in the trust, including the applicable federal, state, local and foreign tax consequences to them and the effect of possible changes in tax laws.

The trust intends to elect be treated and to qualify each year as a "regulated investment company" under Subchapter M of the Internal Revenue Code and to comply with applicable distribution requirements so that it generally will not pay U.S. federal income tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company, which the following discussion assumes, the trust must satisfy certain tests regarding the nature of its income and the diversification of its assets. If the trust qualifies as a regulated investment company and, for each taxable year, it distributes to its shareholders an amount equal to or exceeding the sum of (i) 90% of its "investment company taxable income" as that term is defined in the Internal Revenue Code (which includes, among other things, dividends, taxable interest, and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses) with regard to the deduction for dividends paid and (ii) 90% of the excess of its gross tax-exempt interest, if any, over certain disallowed deductions, the trust generally will be relieved of U.S. federal income tax on any income of the trust, including long-term capital gains, distributed to shareholders. However, if the trust retains any investment company taxable income or "net capital gain" (the excess of net long-term capital gain over net short-term capital loss), it generally will be subject to U.S. federal income tax at

39

regular corporate rates on the amount retained. The trust intends to distribute at least annually all or substantially all of its investment company taxable income, net tax-exempt interest, and net capital gain. If for any taxable year the trust did not qualify as a regulated investment company, it would be treated as a corporation subject to U.S. federal income tax.

Unless a shareholder is ineligible to participate or elects otherwise, distributions will be automatically reinvested in additional common shares of the trust pursuant to the Plan. For U.S. federal income tax purposes, assuming the trust has sufficient current or accumulated earnings and profits, such distributions generally are taxable whether a shareholder takes them in cash or shares or they are reinvested pursuant to the Plan in additional shares of the trust. In general, dividends from investment company taxable income are taxable as ordinary income, and designated dividends from net capital gain, if any, are taxable as long-term capital gains for U.S. federal income tax purposes without regard to the length of time the shareholder has held shares of the trust. The U.S. federal income tax status of all distributions will be reported to shareholders annually.

If the trust retains any net capital gain, the trust may designate the retained amount as undistributed capital gains in a notice to shareholders who, if subject to U.S. federal income tax on long-term capital gains, (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their proportionate shares of such undistributed amount, and (ii) will be entitled to credit their proportionate shares of the tax paid by the trust on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent the credit exceeds such liabilities.

Sales and other dispositions of the trust's shares generally are taxable events for shareholders that are subject to tax. Shareholders should consult their own tax advisers with reference to their individual circumstances to determine whether any particular transaction in the trust's shares is properly treated as a sale for tax purposes, as the following discussion assumes, and the tax treatment of any gains or losses recognized in such transactions. In general, if shares of the trust are sold, the shareholder will recognize gain or loss equal to the difference between the amount realized on the sale and the shareholder's adjusted basis in the shares. Such gain or loss generally will be treated as long-term gain or loss if the shares were held for more than one year and otherwise generally will be treated as short-term gain or loss. Any loss recognized by a shareholder upon the sale or other disposition of shares with a tax holding period of six months or less generally will be treated as a long-term capital loss to the extent of any amounts treated as distributions of long-term capital gain with respect to such shares. Losses on sales or other dispositions of shares may be disallowed under "wash sale" rules in the event of other investments in the trust (including those made pursuant to reinvestment of dividends and/or capital gains distributions) within a period of 61 days beginning 30 days before and ending 30 days after a sale or other disposition of shares.

The trust is required in certain circumstances to backup withhold on reportable payments, including dividends, capital gains distributions, and proceeds of sales or other dispositions of the trust's shares paid to certain holders of the trust's shares who do not furnish the trust with their correct social security number or other taxpayer identification number and certain other certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld from payments made to a shareholder may be refunded or credited against such shareholder's U.S. federal income tax liability, if any, provided that the required information is furnished to the IRS.

The foregoing is a general and abbreviated summary of the provisions of the Internal Revenue Code and the Treasury regulations in effect as they generally affect the taxation of the trust and its shareholders. As noted above, these provisions are subject to change by legislative, judicial or

40

administrative action, and any such change may be retroactive. A further discussion of the U.S. federal income tax rules applicable to the trust can be found in the statement of additional information which is incorporated by reference into this prospectus. Shareholders are urged to consult their tax advisers regarding specific questions as to U.S. federal, foreign, state, and local income or other taxes.

NET ASSET VALUE

The trust calculates a net asset value for its common shares every day the New York Stock Exchange is open when regular trading closes (normally 4:00 p.m. Eastern time). For purposes of determining the net asset value of a common share, the value of the securities held by the trust plus any cash or other assets (including interest accrued but not yet received) minus all liabilities (including accrued expenses and indebtedness) and the aggregate liquidation value of any outstanding preferred shares is divided by the total number of common shares outstanding at such time. Expenses, including the fees payable to Pioneer, are accrued daily. Currently, the net asset values of shares of publicly traded closed-end investment companies investing in debt securities are published in Barron's, the Monday edition of The Wall Street Journal and the Monday and Saturday editions of The New York Times.

The trust generally values its portfolio securities using closing market prices or readily available market quotations. The trust may use a pricing service or a pricing matrix to value some of its assets. When closing market prices or market quotations are not available or are considered by Pioneer to be unreliable, the trust may use a security's fair value. Fair value is the valuation of a security determined on the basis of factors other than market value in accordance with procedures approved by the trust's Trustees. The trust also may use the fair value of a security, including a non-U.S. security, when Pioneer determines that the closing market price on the primary exchange where the security is traded no longer accurately reflects the value of the security due to factors affecting one or more relevant securities markets or the specific issuer. The use of fair value pricing by the trust may cause the net asset value of its shares to differ from the net asset value that would be calculated using closing market prices. International securities markets may be open on days when the U.S. markets are closed. For this reason, the value of any international securities owned by the trust could change on a day you cannot buy or sell shares of the trust. Debt securities with remaining maturities of 60 days or less are valued at amortized cost, which is a method of estimating market value. The value of interest rate swaps, caps and floors is determined in accordance with a formula and then confirmed periodically by obtaining a bank quotation. Positions in options are valued at the last sale price on the market where any such option is principally traded. Positions in futures contracts are valued at closing prices for such contracts established by the exchange on which they are traded. Repurchase agreements are valued at cost plus accrued interest.

DESCRIPTION OF SHARES

The trust is authorized to issue an unlimited number of common shares, without par value. The trust is also authorized to issue preferred shares. After the completion of this offering, the trust will only have common shares outstanding. The Board of Trustees is authorized to classify and reclassify any unissued shares into one or more additional classes or series of shares. The Board of Trustees may establish such series or class, including preferred shares, from time to time by setting or changing in any one or more respects the designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares and pursuant to such classification or reclassification to increase or decrease the number of authorized shares of any existing class or series. The Board of Trustees, without shareholder approval, is

41

authorized to amend the Agreement of Declaration of Trust and by-laws to reflect the terms of any such class or series, including any class of preferred shares. The trust currently anticipates that it will issue preferred shares as soon as practicable after the closing of this offering. See "Leverage." The trust may issue preferred shares. The trust is also authorized to issue other securities, including debt securities.

COMMON SHARES

Common shares, when issued and outstanding, will be fully paid and non-assessable. Shareholders are entitled to share pro rata in the net assets of the trust available for distribution to common shareholders upon liquidation of the trust. Common shareholders are entitled to one vote for each share held.

In the event that the trust issues preferred shares and so long as any shares of the trust's preferred shares are outstanding, holders of common shares will not be entitled to receive any net income of or other distributions from the trust unless all accumulated dividends on preferred shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to preferred shares would be at least 200% after giving effect to such distributions. See "Leverage."

The trust will send unaudited reports at least semiannually and audited annual financial statements to all of its shareholders.

Pioneer provided the initial capital for the trust by purchasing 6,981 shares of common shares of the trust for $100,003. As of the date of this prospectus, Pioneer owned 100% of the outstanding common shares. Pioneer may be deemed to control the trust until such time as it owns less than 25% of the outstanding shares of the trust.

PREFERRED SHARES

The trust in the future may elect to issue preferred shares as part of its leverage strategy. The trust currently anticipates issuing, as soon as practical after the closing of this offering, preferred shares with an aggregate liquidation preference of up to 25% of the trust's total assets, but will be permitted to incur leverage in an amount up to 33 1/3% of the trust's total assets. The Board of Trustees reserves the right to issue preferred shares to the extent permitted by the 1940 Act, which currently limits the aggregate liquidation preference of all outstanding preferred shares to 50% of the value of the trust's total assets less the trust's liabilities and indebtedness. Although the terms of any preferred shares, including dividend rate, liquidation preference and redemption provisions, will be determined by the Board of Trustees, subject to applicable law and the Agreement and Declaration of Trust, it is likely that the preferred shares will be structured to carry a relatively short-term dividend rate reflecting interest rates on short-term bonds by providing for the periodic redetermination of the dividend rate at relatively short intervals through an auction, remarketing or other procedure. The trust also believes that it is likely that the liquidation preference, voting rights and redemption provisions of the preferred shares will be similar to those stated below.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of the trust, the holders of preferred shares will be entitled to receive a preferential liquidating distribution, which is expected to equal the original purchase price per preferred share plus accrued and unpaid dividends, whether or not declared, before any distribution of assets is made to holders of common shares. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of preferred shares will not be entitled to any further participation in any distribution of assets by the trust.

42

The 1940 Act requires that the holders of any preferred shares, voting separately as a single class, have the right to elect at least two Trustees at all times. The remaining Trustees will be elected by holders of common shares and preferred shares, voting together as a single class. In addition, subject to the prior rights, if any, of the holders of any other class of senior securities outstanding, the holders of any preferred shares have the right to elect a majority of the Trustees at any time two years' dividends on any preferred shares are unpaid. The 1940 Act also requires that, in addition to any approval by shareholders that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (1) adopt any plan of reorganization that would adversely affect the preferred shares, and (2) take any action requiring a vote of security holders under Section 13(a) of the 1940 Act, including, among other things, changes in the trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. See "Certain Provisions in the Agreement and Declaration of Trust and By-Laws." As a result of these voting rights, the trust's ability to take any such actions may be impeded to the extent that there are any preferred shares outstanding. The Board of Trustees presently intends that, except as otherwise indicated in this prospectus and except as otherwise required by applicable law, holders of preferred shares will have equal voting rights with holders of common shares (one vote per share, unless otherwise required by the 1940 Act) and will vote together with holders of common shares as a single class.

The affirmative vote of the holders of a majority of the outstanding preferred shares, voting as a separate class, will be required to amend, alter or repeal any of the preferences, rights or powers of holders of preferred shares so as to affect materially and adversely such preferences, rights or powers, or to increase or decrease the authorized number of preferred shares. The class vote of holders of preferred shares described above will in each case be in addition to any other vote required to authorize the action in question.

The terms of the preferred shares are expected to provide that (i) they are redeemable by the trust in whole or in part at the original purchase price per share plus accrued dividends per share, (ii) the trust may tender for or purchase preferred shares and (iii) the trust may subsequently resell any shares so tendered for or purchased. Any redemption or purchase of preferred shares by the trust will reduce the leverage applicable to the common shares, while any resale of shares by the trust will increase that leverage.

The discussion above describes the possible offering of preferred shares by the trust. If the Board of Trustees determines to proceed with such an offering, the terms of the preferred shares may be the same as, or different from, the terms described above, subject to applicable law and the Agreement and Declaration of Trust. The Board of Trustees, without the approval of the holders of common shares, may authorize an offering of preferred shares or may determine not to authorize such an offering, and may fix the terms of the preferred shares to be offered.

CERTAIN PROVISIONS OF THE AGREEMENT AND DECLARATION OF TRUST AND BY-LAWS

The trust's Agreement and Declaration of Trust includes provisions that could have the effect of limiting the ability of other entities or persons to acquire control of the trust or to change the composition of its Board of Trustees and could have the effect of depriving shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the trust.

43

The Board of Trustees is divided into three classes of approximately equal size. The terms of the Trustees of the different classes are staggered so that approximately one third of the Board of Trustees is elected by shareholders each year.

A Trustee may be removed from office with or without cause but only by vote of the holders of at least 75% of the shares entitled to be voted on the matter.

In addition, the Agreement and Declaration of Trust requires the favorable vote of the holders of at least 75% of the trust's shares to approve, adopt or authorize the following:

- a merger or consolidation or statutory share exchange of the trust with any other corporations;

- a sale of all or substantially all of the trust's assets (other than in the regular course of the trust's investment activities); or

- a liquidation or dissolution of the trust;

unless such action has been approved, adopted or authorized by the affirmative vote of at least 75% of the total number of Trustees fixed in accordance with the by-laws, in which case the affirmative vote of a majority of the trust's shares is required. Following any issuance of preferred shares by the trust, it is anticipated that the approval, adoption or authorization of the foregoing also would require the favorable vote of a majority of the trust's shares of preferred shares then entitled to be voted, voting as a separate class.

In addition, conversion of the trust to an open-end investment company would require an amendment to the trust's Agreement and Declaration of Trust. The amendment would have to be declared advisable by the Board of Trustees prior to its submission to shareholders. Such an amendment would require the favorable vote of the holders of at least 75% of the trust's outstanding shares (including any preferred shares) entitled to be voted on the matter, voting as a single class (or a majority of such shares if the amendment was previously approved, adopted or authorized by 75% of the total number of Trustees fixed in accordance with the by-laws), and, assuming preferred shares are issued, the affirmative vote of a majority of outstanding preferred shares, voting as a separate class. Such a vote also would satisfy a separate requirement in the 1940 Act that the change be approved by the shareholders. Shareholders of an open-end investment company may require the company to redeem their shares of common stock at any time (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less such redemption charge, if any, as might be in effect at the time of a redemption. All redemptions will be made in cash. If the trust is converted to an open-end investment company, it could be required to liquidate portfolio securities to meet requests for redemption, and the common shares would no longer be listed on the New York Stock Exchange.

Conversion to an open-end investment company would also require changes in certain of the trust's investment policies and restrictions, such as those relating to the borrowing of money and the purchase of illiquid securities.

In addition, the Agreement and Declaration of Trust requires the favorable vote of a majority of the Trustees followed by the favorable vote of the holders of at least 75% of the outstanding shares of each affected class or series of the trust, voting separately as a class or series, to approve, adopt or authorize certain transactions with 5% or greater holders of a class or series of shares and their associates, unless the transaction has been approved by at least 75% of the Trustees, in which case "a majority of the outstanding voting securities" (as defined in the 1940 Act) of the trust shall be required. For purposes of these provisions, a 5% or greater holder of a class or series of shares (a

44

"Principal Shareholder") refers to any person who, whether directly or indirectly and whether alone or together with its affiliates and associates, beneficially owns 5% or more of the outstanding shares of any class or series of shares of beneficial interest of the trust. The 5% holder transactions subject to these special approval requirements are:

- the merger or consolidation of the trust or any subsidiary of the trust with or into any Principal Shareholder;

- the issuance of any securities of the trust to any Principal Shareholder for cash;

- the sale, lease or exchange of all or any substantial part of the assets of the trust any Principal Shareholder, except assets having an aggregate fair market value of less than $1,000,000, aggregating for the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a 12-month period; or

- the sale, lease or exchange to the trust or any subsidiary of the trust, in exchange for securities of the trust, of any assets of any Principal Shareholder, except assets having an aggregate fair market value of less than $1,000,000, aggregating for purposes of such computation all assets sold, leased or exchanged in any series of similar transactions within a 12-month period.

The Agreement and Declaration of Trust and by-laws provide that the Board of Trustees has the power, to the exclusion of shareholders, to make, alter or repeal any of the by-laws (except for any by-law specified not to be amended or repealed by the Board), subject to the requirements of the 1940 Act. Neither this provision of the Agreement and Declaration of Trust, nor any of the foregoing provisions thereof requiring the affirmative vote of 75% of outstanding shares of the trust, can be amended or repealed except by the vote of such required number of shares.

The trust's by-laws generally require that advance notice be given to the trust in the event a shareholder desires to nominate a person for election to the Board of Trustees or to transact any other business at an annual meeting of shareholders. With respect to an annual meeting following the first annual meeting of shareholders, notice of any such nomination or business must be delivered to or received at the principal executive offices of the trust not less than 90 calendar days nor more than 120 calendar days prior to the anniversary date of the prior year's annual meeting (subject to certain exceptions). In the case of the first annual meeting of shareholders, the notice must be given no later than the tenth calendar day following public disclosure as specified in the by-laws of the date of the meeting. Any notice by a shareholder must be accompanied by certain information as provided in the by-laws.

UNDERWRITING

Subject to the terms and conditions of a purchase agreement dated , 2002, each underwriter named below has severally agreed to purchase, and the trust has agreed to sell to such underwriter, the number of common shares set forth opposite the name of such underwriter.

                                                                  NUMBER OF

                        UNDERWRITER                             -------------

                                                                  ========

The purchase agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to the approval of certain legal matters by counsel and to certain other conditions. The underwriters are obligated to purchase all the common shares sold under the purchase agreement if any of the common shares are purchased. In the purchase agreement, the trust and Pioneer have agreed to indemnify the underwriters against certain liabilities, including liabilities arising under the Securities Act of 1933, or to contribute payments the underwriters may be required to make for any of those liabilities.

The underwriters propose to initially offer some of the common shares directly to the public at the public offering price set forth on the cover page of this prospectus and some of the common shares to certain dealers at the public offering price less a concession not in excess of $ per share. The sales load the trust will pay of $.675 per share is equal to 4.5% of the initial offering price. The underwriters may allow, and the dealers may reallow, a discount not in excess of $ per share on sales to other dealers. After the initial public offering, the public offering price, concession and discount may be changed.

Pioneer has also agreed to pay from its own assets an additional commission to certain underwriters in connection with this offering. The co-lead managing underwriters will be entitled to an additional commission equal to 0.10% per year of the trust's average quarterly total managed assets multiplied by the percentage of the entire offering of the common shares such underwriter sells in this offering. Each other underwriter will also be entitled to this additional commission if such underwriter sells shares with an aggregate offering price of more than $50,000,000 in this offering. This additional commission will be payable quarterly during the continuance of the management contract or other advisory agreement between Pioneer and the trust.

The following table shows the public offering price, sales load and proceeds before expenses to the trust. The information assumes either no exercise or full exercise by the underwriters of their over-allotment option.

                                           PER SHARE    WITHOUT OPTION    WITH OPTION
                                           ---------    --------------    -----------
Public offering price....................    $15.00           $                $
Sales load...............................     $.675           $                $
Proceeds, before expenses, to the
  trust..................................   $14.325           $                $

46

The expenses of the offering are estimated at $689,493 and are payable by the trust. Pioneer has agreed to pay the trust's organizational and offering expenses (other than the sales load) that exceed $0.03 per share. The trust has agreed to pay the underwriters $0.005 per share as a partial reimbursement of expenses incurred in connection with the offering.

The trust has granted the underwriters an option to purchase up to additional common shares at the public offering price, less the sales load, within 45 days from the date of this prospectus solely to cover any over-allotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional shares proportionate to that underwriter's initial amount reflected in the above table.

Until the distribution of the common shares is complete, SEC rules may limit underwriters and selling group members from bidding for and purchasing the trust's common shares. However, the representatives may engage in transactions that stabilize the price of common shares, such as bids or purchases to peg, fix or maintain that price.

If the underwriters create a short position in the trust's common shares in connection with the offering, i.e., if they sell more common shares than are listed on the cover of this prospectus, the representatives may reduce that short position by purchasing common shares in the open market. The representatives may also elect to reduce any short position by exercising all or part of the over-allotment option described above. Purchases of common shares to stabilize its price or to reduce a short position may cause the price of the trust's common shares to be higher than it might be in the absence of such purchases.

Neither the trust nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transaction described above may have on the price of common shares. In addition, neither the trust nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

The trust has agreed not to offer or sell any additional common shares for a period of 180 days after the date of the purchase agreement without the prior written consent of the underwriters, except for the sale of common shares to the underwriters pursuant to the purchase agreement.

The trust anticipates that the underwriters may from time to time act as brokers or dealers in executing the trust's portfolio transactions after they have ceased to be underwriters. The underwriters are active underwriters of, and dealers in, securities and act as market makers in a number of such securities and, therefore, can be expected to engage in portfolio transactions with the trust. Pioneer has retained an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated to provide certain administrative services to the trust on its behalf.

In order to meet the requirements for listing the common shares on the New York Stock Exchange, the underwriters have undertaken to sell (i) common shares to insure a minimum of 100 beneficial holders with a minimum of 100,000 common shares outstanding and (ii) sufficient shares of the common shares so that following this offering, the trust has a minimum aggregate market value of at least $2 million.

CUSTODIAN, TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR

The trust's securities and cash are held under a custodian agreement with Brown Brothers Harriman & Co., 40 Water Street, Boston, Massachusetts 02109. Pioneer Investment Management Shareholder Services Inc. is the trust's transfer agent. The transfer agent has engaged Mellon Investor

47

Services LLC as registrar, shareholder servicing agent and dividend disbursing agent for the trust's shares. Mellon Investor Services LLC's address is 85 Challenger Road, Ridgefield Park, New Jersey 07660.

VALIDITY OF COMMON SHARES

Certain legal matters in connection with the shares offered hereby are passed on for the trust by Hale and Dorr LLP, Boston Massachusetts. Certain matters have been passed upon for the underwriters by Clifford Chance Rogers & Wells LLP, New York, New York.

USE OF PROCEEDS

Pending investment in securities that meet the trust's investment objective and policies, the net proceeds will be invested in accordance with the trust's investment objective and policies during a period not to exceed six months from the closing of this offering. Pending such investment, the net proceeds may be invested in high quality, short-term debt securities. If necessary, the trust may also purchase, as temporary investments, securities of other open- or closed-end investment companies that invest primarily in high yield securities.

INVESTMENT OBJECTIVE AND POLICIES

The prospectus presents the investment objective and the principal investment strategies and risks of the trust. This section supplements the disclosure in the trust's prospectus and provides additional information on the trust's investment policies or restrictions. Restrictions or policies stated as a maximum percentage of the trust's assets are only applied immediately after a portfolio investment to which the policy or restriction is applicable (other than the limitations on borrowing). Accordingly, any later increase or decrease resulting from a change in values, net assets or other circumstances will not be considered in determining whether the investment complies with the trust's restrictions and policies.

PRIMARY INVESTMENTS

Under normal circumstances, the trust invests at least 80% of its assets (net assets plus borrowing) in below investment grade (high yield) debt securities, loans and preferred stocks.

The trust will provide written notice to shareholders at least 60 days prior to any change to the requirement that it invest at least 80% of its assets (net assets plus borrowing) as described in this section.

DEBT OBLIGATIONS OF NON-U.S. GOVERNMENTS

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

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

EURODOLLAR INSTRUMENTS AND SAMURAI AND YANKEE BONDS. The trust may invest in Eurodollar instruments and Samurai and Yankee bonds. Eurodollar instruments are bonds of corporate and government issuers that pay interest and principal in U.S. dollars but are issued in markets outside the United States, primarily in Europe. Samurai bonds are yen-denominated bonds sold in Japan by non-Japanese issuers. Yankee bonds are U.S. dollar-denominated bonds typically issued in the U.S. by non-U.S. governments and their agencies and non-U.S. banks and corporations. The trust may also invest in Eurodollar Certificates of Deposit ("ECDs"), Eurodollar Time Deposits ("ETDs") and Yankee Certificates of Deposit ("Yankee CDs"). ECDs are U.S. dollar-denominated certificates of deposit issued by non-U.S. branches of domestic banks; ETDs are U.S. dollar-denominated deposits in a non-U.S. branch of a U.S. bank or in a non-U.S.

2

bank; and Yankee CDs are U.S. dollar-denominated certificates of deposit issued by a U.S. branch of a non-U.S. bank and held in the U.S. These investments involve risks that are different from investments in securities issued by U.S. issuers, including potential unfavorable political and economic developments, non-U.S. withholding or other taxes, seizure of non-U.S. deposits, currency controls, interest limitations or other governmental restrictions which might affect payment of principal or interest.

RISKS OF NON-U.S. INVESTMENTS

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

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

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

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

3

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

Unanticipated political or social developments may also affect the values of the trust's investments and the availability to the trust of additional investments in such countries. During 1997 and 1998, the political stability, economies and securities and currency markets of many markets in India and the Asian subcontinent experienced significant disruption and declines. There can be no assurances that these economic and market disruptions will not continue or spread to other countries in the region.

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

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

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

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

ECONOMIC MONETARY UNION (EMU). On January 1, 1999, 11 European countries adopted a single currency - the euro. The conversion to the euro was phased in over a three-year period. As of January 1, 2002, there are 15 participating countries and 12 of these countries share the euro as a single currency and single official interest rate and are adhering to agreed upon limits on government borrowing. Budgetary decisions will remain in the hands of each participating country but will be subject to each country's commitment to avoid "excessive deficits" and other more specific budgetary criteria. A European Central Bank is responsible for setting the official interest rate to maintain price stability within the euro zone.

EMU is driven by the expectation of a number of economic benefits, including lower transaction costs, reduced exchange risk, greater competition, and a broadening and deepening of European financial markets. However, there are a number of significant risks associated with EMU. Monetary and economic union on this scale has never been attempted before. There is a significant degree of uncertainty as to whether participating countries will remain committed to EMU in the face of changing economic conditions. This uncertainty may increase the volatility of European markets. A participating country's withdrawal from the EMU could have a negative effect on the trust's non-U.S. investments.

4

INVESTMENTS IN DEPOSITARY RECEIPTS. The trust may hold securities of non-U.S. issuers in the form of American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs") and other similar instruments. Generally, ADRs in registered form are designed for use in U.S. securities markets, and EDRs and GDRs and other similar global instruments in bearer form are designed for use in non-U.S. securities markets.

ADRs are denominated in U.S. dollars and represent an interest in the right to receive securities of non-U.S. issuers deposited in a U.S. bank or correspondent bank. ADRs do not eliminate all the risk inherent in investing in the securities of non-U.S. issuers. However, by investing in ADRs rather than directly in equity securities of non-U.S. issuers, the trust will avoid currency risks during the settlement period for either purchases or sales. EDRs and GDRs are not necessarily denominated in the same currency as the underlying securities which they represent.

For purposes of the trust's investment policies, investments in ADRs, GDRs and similar instruments will be deemed to be investments in the underlying equity securities of non-U.S. issuers. The trust may acquire depositary receipts from banks that do not have a contractual relationship with the issuer of the security underlying the depositary receipt to issue and secure such depositary receipt. To the extent the trust invests in such unsponsored depositary receipts there may be an increased possibility that the trust may not become aware of events affecting the underlying security and thus the value of the related depositary receipt. In addition, certain benefits (i.e., rights offerings) which may be associated with the security underlying the depositary receipt may not inure to the benefit of the holder of such depositary receipt.

MUNICIPAL OBLIGATIONS

The trust may purchase municipal obligations when Pioneer believes that they offer favorable rates of income or capital gain potential when compared to a taxable investment. The term "municipal obligations" generally is understood to include debt obligations issued by municipalities to obtain funds for various public purposes, the interest on which is, in the opinion of bond counsel to the issuer, excluded from gross income for U.S. federal income tax purposes. In addition, if the proceeds from private activity bonds are used for the construction, repair or improvement of privately operated industrial or commercial facilities, the interest paid on such bonds may be excluded from gross income for U.S. federal income tax purposes, although current federal tax laws place substantial limitations on the size of these issues. The trust's distributions of any interest it earns on municipal obligations will be taxable to shareholders as ordinary income.

The two principal classifications of municipal obligations are "general obligation" and "revenue" bonds. General obligation bonds are secured by the issuer's pledge of its faith, credit, and taxing power for the payment of principal and interest. Revenue bonds are payable from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source, but not from the general taxing power. Sizable investments in these obligations could involve an increased risk to the trust should any of the related facilities experience financial difficulties. Private activity bonds are in most cases revenue bonds and do not generally carry the pledge of the credit of the issuing municipality. There are, of course, variations in the security of municipal obligations, both within a particular classification and between classifications.

The mortgage derivatives that the trust may invest in include interests in collateralized mortgage obligations, real estate mortgage investment conduits and stripped mortgage-backed securities.

MORTGAGE-BACKED SECURITIES

The trust may invest in mortgage pass-through certificates and multiple-class pass-through securities, and mortgage derivative securities such as real estate mortgage investment conduits ("REMIC") pass-through certificates, collateralized mortgage obligations (CMOs") and stripped mortgage-backed securities ("SMBS"), interest only mortgage-backed securities and principal only mortgage-backed securities and other types of mortgage-backed securities that may be available in the future. A mortgage-backed security is an obligation of the issuer backed by a mortgage or pool of mortgages or a direct interest in an underlying pool of mortgages. Some mortgage-backed securities, such as CMOs, make payments of both principal and interest at a variety of intervals; others make semiannual interest payments at a predetermined rate and repay principal at maturity (like a typical bond). Mortgage-backed securities are based on different types of mortgages including those on commercial real estate or residential properties. Mortgage-backed securities often have stated maturities of up to thirty years when they are

5

issued, depending upon the length of the mortgages underlying the securities. In practice, however, unscheduled or early payments of principal and interest on the underlying mortgages may make the securities' effective maturity shorter than this, and the prevailing interest rates may be higher or lower than the current yield of the trust's portfolio at the time the trust receives the payments for reinvestment. Mortgage-backed securities may have less potential for capital appreciation than comparable fixed income securities, due to the likelihood of increased prepayments of mortgages as interest rates decline. If the trust buys mortgage-backed securities at a premium, mortgage foreclosures and prepayments of principal by mortgagors (which may be made at any time without penalty) may result in some loss of the trust's principal investment to the extent of the premium paid.

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

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

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

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

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

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

STRIPPED MORTGAGE-BACKED SECURITIES. SMBS are multiple-class mortgage-backed securities that are created when a U.S. government agency or a financial institution separates the interest and principal components of a mortgage-backed security and sells them as individual securities. The trust invests in SMBS that are usually structured with two classes that receive different proportions of interest and principal distributions on a pool of

6

mortgage assets. A typical SMBS will have one class receiving some of the interest and most of the principal, while the other class will receive most of the interest and the remaining principal. The holder of the "principal-only" security ("PO") receives the principal payments made by the underlying mortgage-backed security, while the holder of the "interest-only" security ("IO") receives interest payments from the same underlying security. The prices of stripped mortgage-backed securities may be particularly affected by changes in interest rates. As interest rates fall, prepayment rates tend to increase, which tends to reduce prices of IOs and increase prices of POs. Rising interest rates can have the opposite effect. Although the market for these securities is increasingly liquid, Pioneer may determine that certain stripped mortgage-backed securities issued by the U.S. government, its agencies or instrumentalities are not readily marketable. If so, these securities, together with privately-issued stripped mortgage-backed securities, will be considered illiquid for purposes of the trust's limitation on investments in illiquid securities. The yields and market risk of interest only and principal only SMBS, respectively, may be more volatile than those of other fixed income securities.

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

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

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

MORTGAGE DOLLAR ROLLS. The trust may enter into mortgage "dollar rolls" in which the trust sells securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. During the roll period, the trust loses the right to receive principal and interest paid on the securities sold. However, the trust would benefit to the extent of any difference between the price received for the securities sold and the lower forward price for the future purchase (often referred to as the "drop") or fee income plus the interest earned on the cash proceeds of the securities sold until the settlement date of the forward purchase. Unless such benefits exceed the income, capital appreciation and gain or loss due to mortgage prepayments that would have been realized on the securities sold as part of the mortgage dollar roll, the use of this technique will diminish the investment performance of the trust compared with what such performance would have been without the use of mortgage dollar rolls. All cash proceeds will be invested in instruments that are permissible investments for the trust. The trust will hold and maintain in a segregated account until the settlement date cash or liquid securities in an amount equal to its forward purchase price.

For financial reporting and tax purposes, the trust treats mortgage dollar rolls as two separate transactions; one involving the purchase of a security and a separate transaction involving a sale. The trust does not currently intend to enter into mortgage dollar rolls that are accounted for as financings.

7

Mortgage dollar rolls involve certain risks including the following: if the broker-dealer to whom the trust sells the security becomes insolvent, the trust's right to purchase or repurchase the mortgage-related securities subject to the mortgage dollar roll may be restricted and the instrument which the trust is required to repurchase may be worth less than an instrument which the trust originally held. Successful use of mortgage dollar rolls will depend upon Pioneer's ability to manage its interest rate and mortgage prepayments exposure. For these reasons, there is no assurance that mortgage dollar rolls can be successfully employed.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

The trust may purchase securities, including U.S. government securities, on a when-issued basis or may purchase or sell securities for delayed delivery. In such transactions, delivery of the securities occurs beyond the normal settlement period, but no payment or delivery is made by the trust prior to the actual delivery or payment by the other party to the transaction. The trust will not earn income on these securities until delivered. The purchase of securities on a when-issued or delayed delivery basis involves the risk that the value of the securities purchased will decline prior to the settlement date. The sale of securities for delayed delivery involves the risk that the prices available in the market on the delivery date may be greater than those obtained in the sale transaction. The trust's obligations with respect to when-issued and delayed delivery transactions will be fully collateralized by segregating liquid assets with a value equal to the trust's obligations. See "Asset Segregation."

PREFERRED SHARES

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

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

REITs are companies which invest primarily in income producing real estate or real estate related loans or interests. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of interest payments. REITs are not taxed on income distributed to shareholders provided they comply with the applicable requirements of the Code. The trust will in some cases indirectly bear its proportionate share of any management and other expenses paid by REITs in which it invests in addition to the expenses paid by the trust. Debt securities issued by REITs are, for the most part, general and unsecured obligations and are subject to risks associated with REITs.

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

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

8

REITs may have limited financial resources and may trade less frequently and in a more limited volume than larger company securities.

OTHER INVESTMENT COMPANIES

The trust may invest in the securities of other investment companies to the extent that such investments are consistent with the trust's investment objective and policies and permissible under the Investment Company Act of 1940, as amended (the "1940 Act"). Under the 1940 Act, the trust may not acquire the securities of other domestic or non-U.S. investment companies if, as a result,
(i) more than 10% of the trust's total assets would be invested in securities of other investment companies, (ii) such purchase would result in more than 3% of the total outstanding voting securities of any one investment company being held by the trust, or (iii) more than 5% of the trust's total assets would be invested in any one investment company. These limitations do not apply to the purchase of shares of any investment company in connection with a merger, consolidation, reorganization or acquisition of substantially all the assets of another investment company. The trust does not currently invest in other investment companies for which Pioneer or any of its affiliates act as an investment adviser or distributor. However, Pioneer has applied for, and if granted would rely upon, an exemptive order from the Securities and Exchange Commission (the "SEC") that would permit the trust to invest cash balances in money market funds managed by Pioneer.

The trust, as a holder of the securities of other investment companies, will bear its pro rata portion of the other investment companies' expenses, including advisory fees. These expenses are in addition to the direct expenses of the trust's own operations.

ASSET SEGREGATION

The 1940 Act requires that the trust segregate assets in connection with certain types of transactions that may have the effect of leveraging the trust's portfolio. If the trust enters into a transaction requiring segregation, such as a forward commitment, the custodian or Pioneer will segregate liquid assets in an amount required to comply with the 1940 Act. Such segregated assets will be valued at market daily. If the aggregate value of such segregated assets declines below the aggregate value required to satisfy the 1940 Act, additional liquid assets will be segregated.

INTEREST RATE TRANSACTIONS

INTEREST RATE SWAPS, COLLARS, CAPS AND FLOORS. In order to hedge the value of the trust's portfolio against interest rate fluctuations or to enhance the trust's income, the trust may, but is not required to, enter into various interest rate transactions such as interest rate swaps and the purchase or sale of interest rate caps and floors. To the extent that the trust enters into these transactions, the trust expects to do so primarily to preserve a return or spread on a particular investment or portion of its portfolio or to protect against any increase in the price of securities the trust anticipates purchasing at a later date. The trust intends to use these transactions primarily as a hedge and not as a speculative investment. However, the trust also may invest in interest rate swaps to enhance income or to increase the trust's yield, for example, during periods of steep interest rate yield curves (i.e., wide differences between short-term and long-term interest rates). The trust is not required to hedge its portfolio and may choose not to do so. The trust cannot guarantee that any hedging strategies it uses will work.

In an interest rate swap, the trust exchanges with another party their respective commitments to pay or receive interest (e.g., an exchange of fixed rate payments for floating rate payments). For example, if the trust holds a debt instrument with an interest rate that is reset only once each year, it may swap the right to receive interest at this fixed rate for the right to receive interest at a rate that is reset every week. This would enable the trust to offset a decline in the value of the debt instrument due to rising interest rates but would also limit its ability to benefit from falling interest rates. Conversely, if the trust holds a debt instrument with an interest rate that is reset every week and it would like to lock in what it believes to be a high interest rate for one year, it may swap the right to receive interest at this variable weekly rate for the right to receive interest at a rate that is fixed for one year. Such a swap would protect the trust from a reduction in yield due to falling interest rates and may permit the trust to enhance its income through the positive differential between one week and one year interest rates, but would preclude it from taking full advantage of rising interest rates.

The trust usually will enter into interest rate swaps on a net basis (i.e., the two payment streams are netted out with the trust receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the

9

excess, if any, of the trust's obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis, and an amount of cash or liquid instruments having an aggregate net asset value at least equal to the accrued excess will be maintained in a segregated account by the trust's custodian. If the interest rate swap transaction is entered into on other than a net basis, the full amount of the trust's obligations will be accrued on a daily basis, and the full amount of the trust's obligations will be maintained in a segregated account by the trust's custodian.

The trust also may engage in interest rate transactions in the form of purchasing or selling interest rate caps or floors. The trust will not sell interest rate caps or floors that it does not own. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payments of interest equal to the difference of the index and the predetermined rate on a notional principal amount (i.e., the reference amount with respect to which interest obligations are determined although no actual exchange of principal occurs) from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest at the difference of the index and the predetermined rate on a notional principal amount from the party selling such interest rate floor. The trust will not enter into caps or floors if, on a net basis, the aggregate notional principal amount with respect to such agreements exceeds the net assets of the trust.

Typically, the parties with which the trust will enter into interest rate transactions will be broker-dealers and other financial institutions. The trust will not enter into any interest rate swap, cap or floor transaction unless the unsecured senior debt or the claims-paying ability of the other party thereto is rated investment grade quality by at least one nationally recognized statistical rating organization at the time of entering into such transaction or whose creditworthiness is believed by Pioneer to be equivalent to such rating. If there is a default by the other party to such a transaction, the trust will have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with other similar instruments traded in the interbank market. Caps and floors, however, are less liquid than swaps. Certain federal income tax requirements may limit the trust's ability to engage in interest rate swaps.

CREDIT DEFAULT SWAP AGREEMENTS. The trust may enter into credit default swap agreements. The "buyer" in a credit default contract is obligated to pay the "seller" a periodic stream of payments over the term of the contract provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the "par value" (full notional value) of the reference obligation in exchange for the reference obligation. The trust may be either the buyer or seller in the transaction. If the trust is a buyer and no event of default occurs, the trust loses its investment and recovers nothing. However, if an event of default occurs, the buyer receives full notional value for a reference obligation that may have little or no value. As a seller, the trust receives a fixed rate of income throughout the term of the contract, which typically is between six months and three years, provided that there is no default event. If an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation.

Credit default swaps involve greater risks than if the trust had invested in the reference obligation directly. In addition to general market risks, credit default swaps are subject to illiquidity risk, counterparty risk and credit risks. The trust will enter into swap agreements only with counterparties who are rated investment grade quality by at least one nationally recognized statistical rating organization at the time of entering into such transaction or whose creditworthiness is believed by Pioneer to be equivalent to such rating. A buyer also will lose its investment and recover nothing should no event of default occur. If an event of default were to occur, the value of the reference obligation received by the seller, coupled with the periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the trust. When the trust acts as a seller of a credit default swap agreement it is exposed to many of the same risks of leverage described under "Risk Factors--Leverage" and "Leverage" in the prospectus since if an event of default occurs the seller must pay the buyer the full notional value of the reference obligation.

The trust may in the future employ new or additional investment strategies and hedging instruments if those strategies and instruments are consistent with the trust's investment objective and are permissible under applicable regulations governing the trust.

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

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

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

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

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

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

11

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

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

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

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

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

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

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

12

FOREIGN CURRENCY TRANSACTIONS

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

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

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

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

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

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

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

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

If the trust enters into a forward contract to purchase foreign currency, the custodian or Pioneer will segregate liquid assets.

OPTIONS ON SECURITIES AND SECURITIES INDICES

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

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

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

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

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

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

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

The trust would normally purchase put options in anticipation of a decline in the market value of securities in its portfolio ("protective puts") or in securities in which it may invest. The purchase of a put option would entitle the trust, in exchange for the premium paid, to sell specified securities at a specified price during the option period. The purchase of protective puts is designed to offset or hedge against a decline in the market value of the trust's holdings. Put options may also be purchased by the trust for the purpose of affirmatively benefiting from a decline in the price of securities which it does not own. The trust would ordinarily realize a gain if, during the option period, the value of the underlying securities decreased below the exercise price sufficiently to more than cover the

14

premium and transaction costs; otherwise the trust would realize either no gain or a loss on the purchase of the put option. Gains and losses on the purchase of protective put options would tend to be offset by countervailing changes in the value of the underlying portfolio securities.

The trust may terminate its obligations under an exchange-traded call or put option by purchasing an option identical to the one it has written. Obligations under over-the-counter options may be terminated only by entering into an offsetting transaction with the counterparty to such option. Such purchases are referred to as "closing purchase transactions."

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

Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the Options Clearing Corporation (OCC) may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), in which event the secondary market on that exchange (or in that class or series of options) would cease to exist, although outstanding options on that exchange, if any, that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

The trust may purchase and sell both options that are traded on U.S. and non-U.S. exchanges and options traded over the counter with broker-dealers who make markets in these options. The ability to terminate over-the-counter options is more limited than with exchange-traded options and may involve the risk that broker-dealers participating in such transactions will not fulfill their obligations.

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

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

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

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

INVESTMENT RESTRICTIONS

The following are the trust's fundamental investment restrictions. These restrictions may not be changed without the approval of the holders of a majority of the trust's outstanding voting securities (which for this purpose and under

15

the 1940 Act means the lesser of (i) 67% of the common shares represented at a meeting at which more than 50% of the outstanding common shares are represented or (ii) more than 50% of the outstanding common shares). If the trust were to issue a class of preferred shares, the investment restrictions could not be changed without the approval of a majority of the outstanding common and preferred shares, voting together as a class, and the approval of a majority of the outstanding preferred shares, voting separately by class. Statements in italics are not part of the restriction.

The trust may not:

(1) Issue senior securities, except as permitted by the 1940 Act and the rules and interpretive positions of the SEC thereunder. SENIOR SECURITIES THAT THE TRUST MAY ISSUE IN ACCORDANCE WITH THE 1940 ACT INCLUDE PREFERRED SHARES, BORROWING, FUTURES, WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD FOREIGN CURRENCY EXCHANGE TRANSACTIONS.

(2) Borrow money, except as permitted by the 1940 Act and the rules and interpretive positions of the SEC thereunder.

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

(4) Make loans, except by the purchase of debt obligations, loans or direct claim against a borrower, by entering into repurchase agreements or through the lending of portfolio securities.

(5) Invest in commodities or commodity contracts, except that the trust may invest in currency instruments and contracts and financial instruments and contracts that might be deemed to be commodities and commodity contracts. A FUTURES CONTRACT, FOR EXAMPLE, MAY BE DEEMED TO BE A COMMODITY CONTRACT.

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

(7) With respect to 75% of its total assets, purchase securities of an issuer (other than the U.S. government, its agencies or instrumentalities), if

(a) such purchase would cause more than 5% of the trust's total assets, taken at market value, to be invested in the securities of such issuer, or

(b) such purchase would at the time result in more than 10% of the outstanding voting securities of such issuer being held by the trust.

(8) Concentrate its investments in securities of companies in any particular industry. IN THE OPINION OF THE SEC, INVESTMENTS ARE CONCENTRATED IN A PARTICULAR INDUSTRY IF SUCH INVESTMENTS AGGREGATE 25% OR MORE OF THE TRUST'S TOTAL ASSETS. THE TRUST'S POLICY DOES NOT APPLY TO INVESTMENTS IN U.S. GOVERNMENT SECURITIES.

All other investment policies of the trust in the prospectus under the heading "Investment Objective and Principal Investment Strategies" and in this statement of additional information under the heading "Investment Objective and Policies" are considered non-fundamental and may be changed by the Board of Trustees without prior approval of the trust's outstanding voting shares.

The trust has adopted the following non-fundamental policy: the trust will not incur leverage (whether through the issuance of preferred shares or borrowing) in an amount (at the time of incurrence) greater than 33 1/3% of the trust's total assets.

Under the 1940 Act, the trust may invest up to 10% of its total assets in the aggregate in shares of other investment companies and up to 5% of its total assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased. As a shareholder in any investment company, the trust will bear its ratable share of that investment

16

company's expenses, and would remain subject to payment of the trust's advisory fees and other expenses with respect to assets so invested. Holders of common shares would therefore be subject to duplicative expenses to the extent the trust invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein and in the prospectus. As described in the prospectus in the section entitled "Risks," the net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

In addition, to comply with federal tax requirements for qualification as a "regulated investment company," the trust's investments will be limited in a manner such that at the close of each quarter of each tax year, (a) no more than 25% of the value of the trust's total assets are invested in the securities (other than United States government securities or securities of other regulated investment companies) of a single issuer or two or more issuers controlled by the trust and engaged in the same, similar or related trades or businesses and
(b) with regard to at least 50% of the trust's total assets, no more than 5% of its total assets are invested in the securities (other than United States government securities or securities of other regulated investment companies) of a single issuer. These tax-related limitations may be changed by the Trustees to the extent appropriate in light of changes to applicable tax requirements.

*Mr. Cogan is an Interested Trustee because he is an officer or director of the trust's investment adviser and certain of its affiliates **Mr. Geraci is an Interested Trustee because he is an officer, director and employee of the trust's investment adviser and its affiliates.

The outstanding capital stock of the investment adviser is indirectly majority owned by UniCredito Italiano S.p.A. ("UniCredito"), one of the largest banking groups in Italy.

The trust's Board of Trustees consists of 8 members. The term of one class expires each year commencing with the first annual meeting following this public offering and no term shall continue for more than three years after the applicable election. The terms of Ms. Bush and Ms. Piret expire at the first annual meeting following this public offering, the terms of Mr. Cogan, Dr. Egdahl and Mr. West expire at the second annual meeting, and the terms of Mr. Geraci, Ms. Graham and Mr. Winthrop expire at the third annual meeting. Subsequently, each class of Trustees will stand for election at the conclusion of its respective term. Such classification may prevent replacement of a majority of the Trustees for up to a two-year period.

BOARD COMMITTEES

The Board of Trustees has an Audit Committee, which is comprised of Ms. Piret (chairperson), Mr. West and Mr. Winthrop; a Nominating Committee, which is comprised of Ms. Bush and Dr. Egdahl; a Valuation Committee, which is comprised of Ms. Bush, Ms. Piret and Mr. Winthrop; and an Independent Trustees Committee, which is comprised of all the trust's Independent Trustees. Ms. Graham is the chairperson of the Independent Trustees Committee.

The Board of Trustees has adopted a charter for the Audit Committee. In accordance with its charter, the purposes of the Audit Committee are:

|X| act as a liaison between the trust's independent auditors and the full Board of Trustees of the trust;

|X| discuss with the trust's independent auditors their judgments about the quality of the trust's accounting principles and underlying estimates as applied in the trust's financial reporting;

|X| review and assess the renewal materials of all related party contracts and agreements, including investment advisory agreements, underwriting contracts, administration agreements, and transfer agency contracts, among any other instruments and agreements that may be appropriate from time to time;

|X| review and assess from time to time, as it deems necessary and appropriate:

|X| brokerage and soft dollar arrangements of the trust and

|X| the utilization of any line of credit;

|X| review and approve insurance coverage and allocations of premiums between the management and the trust among the Pioneer Funds;

20

|X| review and approve expenses under the administration agreement between Pioneer and the trust; and

|X| ensure that the independent auditors submit on a periodic basis to the Audit Committee a formal written statement delineating all relationships between the auditors and the trust or Pioneer; to actively engage in a dialogue with the independent auditors with respect to any disclosed relationships or services that may impact the objectivity and independence of the independent auditors; and to recommend that the Trustees take appropriate action in response to the independent auditors' report to satisfy itself of the independent auditors' independence.

The Nominating Committee reviews the qualifications of any candidate recommended by the Independent Trustees to serve as an Independent Trustee and makes a recommendation regarding that person's qualifications. The Committee does not accept nominations from shareholders.

The Valuation Committee reviews the valuation assigned to certain securities by Pioneer in accordance with the trust's valuation procedures.

The Independent Trustees Committee reviews the trust's management contract and other related party contracts annually and is also responsible for any other action required to be taken, under the 1940 Act, by the Independent Trustees acting alone.

The trust's Declaration of Trust provides that the trust will indemnify the Trustees and officers against liabilities and expenses incurred in connection with any litigation in which they may be involved because of their offices with the trust, unless it is determined in the manner specified in the Declaration of Trust that they have not acted in good faith in the reasonable belief that their actions were in the best interests of the trust or that such indemnification would relieve any officer or Trustee of any liability to the trust or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties.

COMPENSATION OF OFFICERS AND TRUSTEES

The trust pays no salaries or compensation to any of its officers. The Pioneer Funds, including the trust, compensate their trustees as follows:

|X| If the Pioneer fund has assets greater than $250 million, the Pioneer fund pays each Independent Trustee an annual base fee calculated on the basis of the Pioneer fund's net assets.
|X| If the Pioneer fund has assets less than $250 million, the Pioneer fund pays each Independent Trustee an annual fee of $1,000.
|X| If the Pioneer fund has assets greater than $50 million, the Pioneer fund pays each Interested Trustee an annual fee of $500, and if the Pioneer fund has assets less than $50 million, the Pioneer fund pays each Interested Trustee and annual fee of $200 (Pioneer reimburses the fund for these fees).
|X| Each Pioneer fund with assets greater than $250 million pays each Independent Trustee who serves on a board committee an annual committee fee based the Pioneer fund's net assets (with additional compensation for chairpersons of such committees).

The following table sets forth certain information with respect to the compensation paid to each Trustee by the trust and the Pioneer funds as a group. Compensation from the trust is for the current calendar year and is estimated. Total compensation from the Pioneer Funds as a group is for the calendar year ended December 31, 2001.

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE MANAGEMENT CONTRACT. The 1940 Act requires that the trust's management contract be approved initially and, after its initial two-year term, annually both by the Board of Trustees and a majority of the Independent Trustees voting separately. The Independent Trustees have determined that the terms of the trust's management contract are fair and reasonable and that the agreement is in the trust's best interests. The Independent Trustees believe that the management contract will enable the trust to enjoy high quality investment advisory services at a cost which they deem appropriate, reasonable and in the best interests of the trust and its shareholders. In making such determinations, the Independent Trustees met independently from the interested Trustees of the trust and any officers of Pioneer or its affiliates. The Independent Trustees also relied upon the assistance of counsel to the Independent Trustees and counsel to the trust.

In evaluating the management contract, the Independent Trustees reviewed materials furnished by Pioneer and discussed with representatives of Pioneer the trust's operations and the Pioneer's ability to provide advisory and other services to the trust. The Independent Trustees also reviewed, among other things:

|X| the investment performance of other Pioneer funds with similar investment strategies;

|X| the proposed fees to be charged by Pioneer for investment advisory services;

|X| the trust's projected total operating expenses;

|X| the fees and total expenses of investment companies with similar objectives and strategies managed by other investment advisers;

|X| the experience of the investment advisory and other personnel providing services to the trust and the historical quality of the services provided by Pioneer; and

|X| Pioneer's policy with respect to soft dollar benefits generated by the trust's portfolio transactions.

The Independent Trustees considered the following as relevant to their recommendations: (1) the favorable history, reputation, qualification and background of Pioneer and UniCredito, as well as the qualifications of their personnel and their respective financial conditions; (2) that the fee and expense ratios of the trust are reasonable given the quality of services expected to be provided and are comparable to the fee and expense ratios of similar investment companies; (3) the relative performance of other funds managed by Pioneer with similar objectives compared to the results of other comparable investment companies and unmanaged indices; and (4) other factors that the Independent Trustees deemed relevant. The Independent Trustees deemed each of these factors to be relevant to their consideration of the management contract.

CODE OF ETHICS

The trust and Pioneer have adopted a code of ethics under Rule 17j-1 of the 1940 Act which is applicable to officers, directors/trustees and designated employees of Pioneer and PIML. The code permits such persons to engage in personal securities transactions for their own accounts, including securities that may be purchased or held by the trust, and is designed to prescribe means reasonably necessary to prevent conflicts of interest from arising in connection with personal securities transactions. The code is filed as an exhibit to the trust's registration statement. Consequently, it is on public file with and available from the SEC at the address or website listed in the prospectus.

INVESTMENT ADVISER

The trust has contracted with Pioneer to act as its investment adviser. Pioneer is an indirect, majority owned subsidiary of UniCredito. Pioneer is part of the global asset management group providing investment management and financial services to mutual funds, institutional and other clients. As of December 31, 2001, assets under management were approximately $99 billion worldwide, including over $19 billion in assets under management by Pioneer. Certain Trustees or officers of the trust are also directors and/or officers of certain of UniCredito's subsidiaries. Pioneer has entered into an agreement with its affiliate, PIML, pursuant to which PIML provides certain services and personnel to Pioneer.

24

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

Under the management contract, Pioneer is not liable to the trust except by willful malfeasance, bad faith, gross negligence or reckless disregard of its duties and obligations. In providing its services to the trust, Pioneer may draw upon the research and investment management expertise of Pioneer's affiliate, PIML.

Pioneer has also entered into an administration agreement with the trust pursuant to which Pioneer provides certain administrative services to the trust. Under the administration agreement, the trust will reimburse Pioneer for its cost of providing administrative services to the trust, but the trust will not reimburse Pioneer for the fees of any sub-administrator retained by Pioneer. Pioneer has retained Princeton Administrators L.P. (Princeton), an affiliate of Merrill Lynch, to provide certain administrative services to the trust on Pioneer's behalf. Pioneer will pay Princeton a fee for such services. The administration agreement may be terminated by the trust or Pioneer (without penalty) at any time upon not less than 60 days' prior written notice to the other party to the agreement.

PIMSS has entered into a transfer agency agreement with the trust pursuant to which PIMSS provides certain transfer agency services to the trust. Under the transfer agency agreement, the trust will reimburse PIMSS for its cost of providing such services to the trust. PIMSS has retained Mellon Investor Services LLC (Mellon) to provide sub-transfer agent, registrar, shareholder servicing agent and dividend dispersing agent services for the trust. The trust will pay Mellon a fee for such services. The transfer agency agreement may be terminated by the trust or PIMSS (without penalty) at any time upon not less than 60 days' prior written notice to the other party to the agreement.

DIRECT REGISTRATION OF TRUST SHARES. Through Mellon, the trust has made its common shares eligible for inclusion in the direct registration system (DRS) administered by The Depository Trust Company (DTC), wherein Mellon will process transfers of common shares utilizing DTC's Profile Modification System.

COMPENSATION AND EXPENSES

Under the management contract, the trust will pay to Pioneer monthly, as compensation for the services rendered and expenses paid by it, a fee equal on an annual basis to 0.60% of the trust's average weekly managed assets. Because the fees paid to Pioneer are determined on the basis of the trust's managed assets, Pioneer's interest in determining whether to leverage the trust may differ from the interests of the trust. The advisory fee payable by the trust to Pioneer is higher than the fees paid by most U.S. investment companies.

The trust's average weekly managed assets are determined for the purpose of calculating the advisory fee by taking the average of all the weekly determinations of total assets during a given calendar month. The fee is payable for each calendar month as soon as practicable after the end of that month.

Under the terms of its management contract with the trust, Pioneer pays all the operating expenses, including executive salaries and the rental of office space, relating to its services for the trust, with the exception of the following, which are to be paid by the trust: (a) charges and expenses for fund accounting, pricing and appraisal services and related overhead, including, to the extent such services are performed by personnel of Pioneer or its affiliates, office space and facilities and personnel compensation, training and benefits; (b) the charges and expenses of auditors; (c) the charges and expenses of any administrator, custodian, transfer agent, plan agent, dividend disbursing agent and registrar appointed by the trust; (d) issue and transfer taxes chargeable to the trust in connection with securities transactions to which the trust is a party; (e) insurance premiums, interest charges, dues and fees for membership in trade associations and all taxes and corporate fees payable by the trust to federal, state or other governmental agencies; (f) fees and expenses involved in registering and maintaining registrations of the trust and/or its shares with federal regulatory agencies, state or blue sky securities agencies and foreign jurisdictions, including the preparation of prospectuses and statements of additional information for filing with such regulatory authorities; (g) all expenses of shareholders' and Trustees' meetings and of preparing, printing and distributing prospectuses, notices, proxy statements and all reports to shareholders and to governmental agencies; (h) charges and expenses of legal

25

counsel to the trust and the Trustees; (i) compensation of those Trustees of the trust who are not affiliated with or interested persons of Pioneer or the trust (other than as Trustees); (j) the cost of preparing and printing share certificates; (k) interest on borrowed money, if any; and (l) the fees and other expenses of listing the trust's shares on the New York Stock Exchange or any other national stock exchange. In addition, the trust shall pay all brokers' and underwriting commissions chargeable to the trust in connection with securities transactions to which the trust is a party.

DURATION AND TERMINATIONS; NONEXCLUSIVE SERVICES

The economic terms of the investment advisory agreement were approved by the trust's Board of Trustees at a meeting of the Board of Trustees held on March 12, 2002, including a majority of the Trustees who are not parties to the agreement or interested persons of any such party (as such term is defined in the 1940 Act). The 1940 Act requires that the investment advisory agreement be approved by a majority of the trust's Board of Trustees, including a majority of the Trustees who are not interested persons as that term is defined in the 1940 Act, at an in person meeting of the Board of Trustees.

The investment advisory agreement was approved by the sole common shareholder of the trust as of March 18, 2002.

Unless earlier terminated as described below, the management contract will remain in effect for two years from the date of its execution and from year to year thereafter if approved annually (i) by a majority of the Independent Trustees of the trust and (ii) by the Board of Trustees or by a majority of the outstanding voting securities of the trust. The management contract may be terminated without penalty on 60 days' written notice by either party thereto or by a vote of a majority of the outstanding voting securities of the trust and will terminate in the event it is assigned (as defined in the 1940 Act). The services of Pioneer are not deemed to be exclusive, and nothing in the relevant agreement will prevent Pioneer or its affiliates from providing similar services to other investment companies and other clients (whether or not their investment objectives and policies are similar to those of the trust) or from engaging in other activities.

POTENTIAL CONFLICTS OF INTEREST

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

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

26

PORTFOLIO TRANSACTIONS

All orders for the purchase or sale of portfolio securities are placed on behalf of the trust by Pioneer pursuant to authority contained in the trust's management contract. Securities purchased and sold on behalf of the trust normally will be traded in the over-the-counter market on a net basis (i.e., without commission) through dealers acting for their own account and not as brokers or otherwise through transactions directly with the issuer of the instrument. The cost of securities purchased from underwriters includes an underwriter's commission or concession, and the prices at which securities are purchased and sold from and to dealers include a dealer's markup or markdown. Pioneer normally seeks to deal directly with the primary market makers unless, in its opinion, better prices are available elsewhere. Some securities are purchased and sold on an exchange or in over-the-counter transactions conducted on an agency basis involving a commission. Pioneer seeks to obtain the best execution on portfolio trades. The price of securities and any commission rate paid are always factors, but frequently not the only factors, in judging best execution. In selecting brokers or dealers, Pioneer considers various relevant factors, including, but not limited to, the size and type of the transaction; the nature and character of the markets for the security to be purchased or sold; the execution efficiency, settlement capability and financial condition of the dealer; the dealer's execution services rendered on a continuing basis; and the reasonableness of any dealer spreads. Transactions in non-U.S. equity securities are executed by broker-dealers in non-U.S. countries in which commission rates may not be negotiable (as such rates are in the U.S.).

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

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

In circumstances where two or more broker-dealers offer comparable prices and executions, preference may be given to a broker-dealer which has sold shares of the trust as well as shares of other investment companies managed by Pioneer. This policy does not imply a commitment to execute all portfolio transactions through all broker-dealers that sell shares of the trust. The Pioneer funds have entered into third-party brokerage and/or expense offset arrangements to reduce the funds' total operating expenses. Pursuant to third-party brokerage arrangements, certain of the funds that invest primarily in U.S. equity securities may incur lower custody fees by directing brokerage to third-party broker-dealers. Pursuant to expense offset arrangements, the funds incur lower transfer agency expenses by maintaining their cash balances with the custodian.

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

27

REPURCHASE OF COMMON SHARES

The trust is a closed-end investment company and as such its shareholders will not have the right to cause the trust to redeem their shares. Instead, the trust's common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, dividend stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Shares of closed-end funds frequently trade at a discount to their net asset value. Common shares of closed-end investment companies like the trust that invest predominantly in high yield securities have during some periods traded at prices higher than their net asset value (at a "premium") and during other periods traded at prices lower than their net asset value (at a "discount"). This is in part because the market price reflects the dividend yield on the common shares. When the yield on the net asset value per share is higher than yields generally available in the market for comparable securities, the market price will tend to reflect this by trading higher than the net asset value per share to adjust the yield to a comparable market rate. To the extent the common shares do trade at a discount, the trust's Board of Trustees may from time to time engage in open market repurchases or tender offers for shares after balancing the benefit to shareholders of the increase in the net asset value per share resulting from such purchases against the decrease in the assets of the trust and potential increase in the expense ratio of expenses to assets of the trust and consequent reduction in yield. The Board of Trustees believes that in addition to the beneficial effects described above, any such purchases or tender offers may result in the temporary narrowing of any discount but will not have any long-term effect on the level of any discount.

At any time when the trust's preferred shares are outstanding, the trust may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accrued preferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the trust's portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value of the outstanding preferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). Any service fees incurred in connection with any tender offer made by the trust will be borne by the trust and will not reduce the stated consideration to be paid to tendering shareholders.

Subject to its investment restrictions, the trust may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the trust in anticipation of share repurchases or tenders will reduce the trust's net income. Any share repurchase, tender offer or borrowing that might be approved by the trust's Board of Trustees would have to comply with the Exchange Act, the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from net asset value will be made by the Board of Trustees at the time it considers such issue, it is the board's present policy, which may be changed by the Board of Trustees, not to authorize repurchases of common shares or a tender offer for such shares if: (1) such transactions, if consummated, would (a) result in the delisting of the common shares from the New York Stock Exchange, or (b) impair the trust's status as a regulated investment company under the Code, (which would make the trust a taxable entity, causing the trust's income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the trust) or as a registered closed-end investment company under the 1940 Act; (2) the trust would not be able to liquidate portfolio securities in an orderly manner and consistent with the trust's investment objective and policies in order to repurchase shares; or (3) there is, in the board's judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the trust, (b) general suspension of or limitation on prices for trading securities on the New York Stock Exchange, (c) declaration of a banking moratorium by federal or state authorities or any suspension of payment by United States or New York banks, (d) material limitation affecting the trust or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the trust or its shareholders if shares were repurchased. The Board of Trustees may in the future modify these conditions in light of experience.

The repurchase by the trust of its shares at prices below net asset value will result in an increase in the net asset value of those shares that remain outstanding. However, there can be no assurance that share repurchases or tender offers at or below net asset value will result in the trust's shares trading at a price equal to their net asset value. Nevertheless, the fact that the trust's shares may be the subject of repurchase or tender offers from time to time, or

28

that the trust may be converted to an open-end investment company, may reduce any spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the trust of its common shares will decrease the trust's total assets which would likely have the effect of increasing the trust's expense ratio. Any purchase by the trust of its common shares at a time when preferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining.

Before deciding whether to take any action if the common shares trade below net asset value, the trust's Board of Trustees would likely consider all relevant factors, including the extent and duration of the discount, the liquidity of the trust's portfolio, the impact of any action that might be taken on the trust or its shareholders and market considerations. Based on these considerations, even if the trust's shares should trade at a discount, the Board of Trustees may determine that, in the interest of the trust and its shareholders, no action should be taken.

U.S. FEDERAL INCOME TAX MATTERS

The following is a summary discussion of certain U.S. federal income tax consequences that may be relevant to a shareholder of acquiring, holding and disposing of common shares of the trust. This discussion only addresses U.S. federal income tax consequences to U.S. shareholders who hold their shares as capital assets and does not address all of the U.S. federal income tax consequences that may be relevant to particular shareholders in light of their individual circumstances. This discussion also does not address the tax consequences to shareholders who are subject to special rules, including, without limitation, financial institutions, insurance companies, dealers in securities or foreign currencies, foreign holders, persons who hold their shares as or in a hedge against currency risk, a constructive sale, or conversion transaction, holders who are subject to the alternative minimum tax, or tax-exempt or tax-deferred plans, accounts, or entities. In addition, the discussion does not address any state, local, or foreign tax consequences, and it does not address any federal tax consequences other than U.S. federal income tax consequences. The discussion reflects applicable tax laws of the United States as of the date of this statement of additional information, which tax laws may be changed or subject to new interpretations by the courts or the Internal Revenue Service (the "IRS") retroactively or prospectively. No attempt is made to present a detailed explanation of all U.S. federal income tax concerns affecting the trust and its shareholders, and the discussion set forth herein does not constitute tax advice. Investors are urged to consult their own tax advisers to determine the tax consequences to them of investing in the trust, including the applicable federal, state, local and foreign tax consequences to them and the effect of possible changes in tax laws.

The trust intends to elect be treated and to qualify each year as a "regulated investment company" under Subchapter M of the Code and to comply with applicable distribution requirements so that it generally will not pay U.S. federal income tax on income and capital gains distributed to shareholders. In order to qualify as a regulated investment company under Subchapter M of the Code, which this discussion assumes, the trust must, among other things, derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies (the "90% income test") and satisfy certain quarterly diversification requirements. For purposes of the 90% income test, the character of income earned by certain entities in which the trust invests that are not treated as corporations (e.g., partnerships or trusts) for U.S. federal income tax purposes will generally pass through to the trust. Consequently, the trust may be required to limit its equity investments in such entities that earn fee income, rental income or other nonqualifying income.

If the trust qualifies as a regulated investment company and, for each taxable year, it distributes to its shareholders an amount equal to or exceeding the sum of (i) 90% of its "investment company taxable income" as that term is defined in the Code (which includes, among other things, dividends, taxable interest, and the excess of any net short-term capital gains over net long-term capital losses, as reduced by certain deductible expenses) without regard to the deduction for dividends paid and (ii) 90% of the excess of its gross tax-exempt interest, if any, over certain disallowed deductions, the trust will generally be relieved of U.S. federal income tax on any income of the trust, including long-term capital gains, distributed to shareholders. However, if the trust retains any investment company taxable income or "net capital gain" (the excess of net long-term capital gain over net short-term capital loss), it generally will be subject to U.S. federal income tax at regular corporate rates on the amount retained. The trust intends to distribute at least annually all or substantially all of its investment company taxable income, net tax-exempt

29

interest, and net capital gain. If for any taxable year the trust did not qualify as a regulated investment company, it would be treated as a corporation subject to U.S. federal income tax.

Under the Code, the trust will be subject to a nondeductible 4% federal excise tax on a portion of its undistributed ordinary income and capital gains if it fails to meet certain distribution requirements with respect to each calendar year. The trust intends to make distributions in a timely manner and accordingly does not expect to be subject to the excise tax, but, as described below, there can be no assurance that the trust's distributions will be sufficient to avoid entirely this tax.

Commencing within approximately 90 days from the date of this statement of additional information, the trust intends to declare a dividend from all or a portion of its net investment income monthly. The trust intends to distribute any net short- and long-term capital gains at least annually. Dividends from income and/or capital gains may also be paid at such other times as may be necessary for the trust to avoid U.S. federal income or excise tax.

Unless a shareholder is ineligible to participate or elects otherwise, distributions will be automatically reinvested in additional common shares of the trust pursuant to the Automatic Dividend Reinvestment Plan (the "Plan"). For U.S. federal income tax purposes, such distributions generally are taxable whether a shareholder takes them in cash or they are reinvested pursuant to the Plan in additional shares of the trust. In general, assuming there are sufficient earnings and profits, dividends from investment company taxable income are taxable as ordinary income, and designated dividends from net capital gain, if any, are taxable as long-term capital gains for U.S. federal income tax purposes without regard to the length of time the shareholder has held shares of the trust. Distributions by the trust in excess of the trust's current and accumulated earnings and profits will be treated as a return of capital to the extent of (and in reduction of) the shareholder's tax basis in its shares, and any such amount in excess of that basis will be treated as gain from the sale of the shares as discussed below. The U.S. federal income tax status of all distributions will be reported to shareholders annually.

If the trust retains any net capital gain, the trust may designate the retained amount as undistributed capital gains in a notice to shareholders who, if subject to U.S. federal income tax on long-term capital gains, (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their proportionate shares of such undistributed amount, and (ii) will be entitled to credit their proportionate shares of the tax paid by the trust on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent the credit exceeds such liabilities.

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

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

If the trust acquires any equity interest (under future Treasury regulations, generally including not only stock but also an option to acquire stock such as is inherent in a convertible bond) in certain foreign corporations that receive at least 75% of their annual gross income from passive sources (such as interest, dividends, certain rents and royalties, or capital gains) or that hold at least 50% of their assets in investments producing such passive income ("passive foreign investment companies"), the trust could be subject to U.S. federal income tax and additional interest charges on "excess distributions" received from such companies or on gain from the disposition of stock in such companies, even if all income or gain actually received by the trust is timely distributed to its shareholders. The trust would not be able to pass through to its shareholders any credit or deduction for such a tax. An election may generally be available that would ameliorate these adverse tax consequences, but any such election could require

30

the trust to recognize taxable income or gain (subject to tax distribution requirements) without the concurrent receipt of cash. These investments could also result in the treatment of associated capital gains as ordinary income. The trust may limit and/or manage its holdings in passive foreign investment companies to limit its tax liability or maximize its return from these investments.

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

If the trust utilizes leverage through borrowing, a failure by the trust to meet the asset coverage requirements imposed by the 1940 Act or by any rating organization that has rated such leverage or additional restrictions that may be imposed by certain lenders on the payment of dividends or distributions potentially could limit or suspend the trust's ability to make distributions on its common shares. Such a suspension or limitation could prevent the trust from distributing at least 90% of its net income as is required under the Code and therefore might jeopardize the trust's reduction or exemption from corporate taxation as a regulated investment company and/or might subject the trust to the 4% excise tax. Upon any failure to meet such asset coverage requirements, the trust may, in its sole discretion, purchase or redeem shares of preferred stock in order to maintain or restore the requisite asset coverage and avoid the adverse consequences to the trust and its shareholders of failing to satisfy the distribution requirement. There can be no assurance, however, that any such action would achieve these objectives. The trust will endeavor to avoid restrictions on its ability to distribute dividends.

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

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

Sales and other dispositions of the trust's shares generally are taxable events for shareholders that are subject to tax. Shareholders should consult their own tax advisers with reference to their individual circumstances to determine whether any particular transaction in the trust's shares is properly treated as a sale for tax purposes, as the following discussion assumes, and the tax treatment of any gains or losses recognized in such transactions. In general, if trust shares are sold, the shareholder will recognize gain or loss equal to the difference between the amount realized on the sale and the shareholder's adjusted basis in the shares. Such gain or loss generally will be treated as long-term gain or loss if the shares were held for more than one year and otherwise generally will be treated as short-term gain or loss. Any loss recognized by a shareholder upon the sale or other disposition of shares with a tax holding period of six months or less generally will be treated as a long-term capital loss to the extent of any amounts treated as distributions of long-term capital gain with respect to such shares. Losses on sales or other dispositions of shares may be disallowed under "wash sale" rules in the event of other investments in the trust (including those made pursuant to reinvestment of dividends and/or capital gain distributions) within a period of 61 days beginning 30 days before and ending 30 days after a sale or other disposition of shares.

Options written or purchased and futures contracts entered into by the trust on certain securities, indices and foreign currencies, as well as certain forward foreign currency contracts, may cause the trust to recognize gains or losses

31

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

The trust may invest in REITs that hold residual interests in REMICs. Under Treasury regulations that have not yet been issued, but may apply retroactively, a portion of the trust's income from a REIT that is attributable to the REIT's residual interest in a REMIC (referred to in the Code as an "excess inclusion") will be subject to federal income tax in all events. These regulations are also expected to provide that excess inclusion income of a regulated investment company, such as the trust, will be allocated to shareholders of the regulated investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related REMIC residual interest directly. In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on unrelated business income, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a foreign shareholder, will not qualify for any reduction in U.S. federal withholding tax. In addition, if at any time during any taxable year a "disqualified organization" (as defined in the Code) is a record holder of a share in a regulated investment company, then the regulated investment company will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the highest federal income tax rate imposed on corporations. Pioneer does not intend on behalf of the trust to invest in REITs, a substantial portion of the assets of which consists of residual interest in REMICs.

The trust's distributions to its corporate shareholders would potentially qualify in their hands for the corporate dividends-received deduction subject to certain holding period requirements and limitations on debt financings under the Code, only to the extent the trust earned dividend income from stock investments in U.S. domestic corporations and certain other requirements are satisfied. The trust is permitted to acquire stocks of U.S. domestic corporations, and it is therefore possible that a small portion of the trust's distributions, from the dividends attributable to such stocks, may qualify for the dividends-received deduction. Such qualifying portion, if any, may affect a corporate shareholder's liability for alternative minimum tax and/or result in basis reductions and other consequences in certain circumstances.

The Internal Revenue Service has taken the position that if a regulated investment company has two classes of shares, it must designate distributions made to each class in any year as consisting of no more than such class's proportionate share of particular types of income, including dividends qualifying for the corporate dividends-received deduction (if any) and net capital gains. A class's proportionate share of a particular type of income is determined according to the percentage of total dividends paid by the regulated investment company during the year to such class. Consequently, if both common shares and preferred shares are outstanding, the trust intends to designate distributions made to the classes of particular types of income in accordance with the classes' proportionate shares of such income. Thus, the trust will designate dividends qualifying for the corporate dividends-received deduction (if any), income not qualifying for the dividends-received deduction and net

32

capital gains in a manner that allocates such income between the holders of common shares and preferred shares in proportion to the total dividends paid to each class during or for the taxable year, or otherwise as required by applicable law.

The trust may be subject to withholding and other taxes imposed by foreign countries, including taxes on interest, dividends and capital gains with respect to its investments in those countries, which would, if imposed, reduce the yield on or return from those investments. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes in some cases. The trust does not expect to satisfy the requirements for passing through to its shareholders their pro rata shares of qualified foreign taxes paid by the trust, with the general result that shareholders would not include such taxes in their gross incomes and would not be entitled to a tax deduction or credit for such taxes on their own tax returns.

Federal law requires that the trust withhold (as "backup withholding") on reportable payments, including dividends, capital gain distributions and the proceeds of sales or other dispositions of the trust's shares paid to certain shareholders who have not complied with IRS regulations. In order to avoid this withholding requirement, shareholders must certify on their Account Applications, or on separate IRS Forms W-9, that the Social Security Number or other Taxpayer Identification Number they provide is their correct number and that they are not currently subject to backup withholding, or that they are exempt from backup withholding. The trust may nevertheless be required to withhold if it receives notice from the IRS or a broker that the number provided is incorrect or backup withholding is applicable as a result of previous underreporting of income.

The description of certain federal tax provisions above relates only to U.S. federal income tax consequences for shareholders who are U.S. persons,
i.e., U.S. citizens or residents or U.S. corporations, partnerships, trusts or estates, and who are subject to U.S. federal income tax. Investors other than U.S. persons may be subject to different U.S. tax treatment, including a non-resident alien U.S. withholding tax on amounts treated as ordinary dividends from the trust and, unless an effective IRS Form W-8BEN or other authorized withholding certificate is on file, to backup withholding on certain other payments from the trust. Shareholders should consult their own tax advisers on these matters and on any specific questions as to U.S. federal, foreign, state, local and other applicable tax laws.

PERFORMANCE-RELATED, COMPARATIVE AND OTHER INFORMATION

PERFORMANCE-RELATED INFORMATION. The trust may quote certain performance-related information and may compare certain aspects of its portfolio and structure to other similar closed-end funds as categorized by Lipper, Inc. (Lipper), Morningstar Inc. or other independent services. Comparison of the trust to an alternative investment should be made with consideration of differences in features and expected performance. The trust may obtain data from sources or reporting services, such as Bloomberg Financial and Lipper, that the trust believes to be generally accurate.

From time to time, the trust and/or Pioneer may report to shareholders or to the public in advertisements concerning Pioneer's performance as an advisor to Pioneer mutual funds and clients other than the trust, or on the comparative performance or standing of Pioneer in relation to other money managers. Pioneer may also provide to current or prospective private account clients, in connection with standardized performance information for the trust, performance information for the trust gross of fees and expenses for the purpose of assisting such clients in evaluating similar performance information provided by other investment managers or institutions. Comparative information may be compiled or provided by independent ratings services or by news organizations. Performance information for the trust or for other Pioneer mutual funds or accounts managed by Pioneer may also be compared to various unmanaged indexes or to other benchmarks, some of which may not be available for direct investment. Any performance information, whether related to the trust or Pioneer, should be considered in light of the trust's investment objective and policies, the characteristics and quality of the trust, and the market conditions during the time period indicated, and it should not be considered to be representative of what may be achieved in the future. Pioneer may provide its opinion with respect to general economic conditions including such matters as trends in default rates or economic cycles.

Past performance is not indicative of future results. At the time common shareholders sell their shares, they may be worth more or less than their original investment. At any time in the future, yields and total return may be higher or lower than past yields and total return, and there can be no assurance that any historical results will continue.

PIONEER. From time to time, Pioneer or the trust may use, in advertisements or information furnished to present or prospective shareholders, information regarding Pioneer including, without limitation, information regarding Pioneer's investment style, countries of operation, organization, professional staff, clients (including other registered investment companies), assets under management and performance record. These materials may refer to opinions or rankings of Pioneer's overall investment management performance contained in third-party reports or publications. Pioneer's U.S. mutual fund investment history includes creating in 1928 one of the first mutual funds. Pioneer has traditionally served a mutual fund and an institutional clientele. As of December 31, 2001, Pioneer and its affiliates managed approximately $98 billion in assets worldwide, including over $19 billion in assets under management by Pioneer for U.S. investors. Pioneer and its affiliates manage over 100 mutual funds registered in the United States or other jurisdictions and employ over 1,200 multicultural professionals in 12 countries. Pioneer and its affiliates utilize a network of 3,000 distributors worldwide.

Advertisements for the trust may make reference to certain other open- or closed-end investment companies managed by Pioneer. In 1999, 1999 and 2000, Pioneer introduced Pioneer Strategic Income Fund, Pioneer Strategic Income VCT Portfolio and Pioneer High Yield VCT Portfolio. In 2000 Pioneer introduced Pioneer High Yield Fund, and pursuant to an agreement and plan of reorganization, that Pioneer fund acquired all of the assets of Third Avenue High Yield Fund. (In the reorganization, Third Avenue High Yield Fund exchanged all of its assets for Class A shares of Pioneer High Yield Fund. The performance of each class of Pioneer High Yield Fund from February 12, 1998 to February 25, 2000 includes the performance of Third Avenue High Yield Fund's single class.) Each of the referenced Pioneer funds is an open-end investment company that does not employ leverage. The investment objective, policies and restrictions applicable to each of these funds differ in material respects from the trust's objective, policies and restrictions. These differences may affect performance.

Pioneer may present an investment allocation model demonstrating the trust's weightings in investment types, sectors or rating categories such as U.S. high yield, emerging markets or investment grade securities. The model allocations are representative of the trust's investment strategy, Pioneer's analysis of the market for high yield securities as of the date of the model and certain factors that may alter the allocation percentages include global economic conditions, individual company fundamentals or changes in market valuations. Such models may also indicate an expected or targeted weighted average rating of the trust's portfolio.

COMPARATIVE INFORMATION. From time to time, the trust's advertisements or information furnished to present or prospective shareholders may refer to the returns and yields offered by various types of investments, as well as the yield spreads on such investments. For instance, such advertisements may refer to the spread in corporate bond yield and government bond yield, or the yield of other types of investments. For purposes of advertisements or related materials, yields and returns may be measured by various indices such as the Lehman Municipal Bond Index, the Merrill Lynch Global Bond Index, the Merrill Lynch Government Master Index, the Merrill Lynch Mortgage Master Index or other such indices. Advertisements and related materials may also note Pioneer's belief that yields on short-term, intermediate- and long-term bonds offer attractive current yields and set forth yields on other investments, including without limitation, 3-month T-Bills, 10-year Treasury bonds and 30-year Treasury bonds.

The trust's advertising materials may also compare the performance of investment companies with differing investment styles, objectives or portfolio securities. Returns for investment companies that invest primarily in bonds may be compared with the returns of investment companies that invest primarily in equities. Such material may also assert that, in an uncertain equity environment, bonds can provide an attractive alternative to equity investments. The trust's advertising materials may also include comparative graphics, for example:

NOTES

1. ORGANIZATION

Pioneer High Income Trust (the "Trust") is a diversified, closed-end management investment company organized on January 30, 2002, which has had no operations other than the sale and issuance of 6,981 shares at an aggregate purchase price of $100,003 to Pioneer Investment Management, Inc. (the "Investment Adviser") on March 18, 2002. The Investment Adviser has agreed to reimburse the amount by which the aggregate of all of the Trust's organizational expenses and all offering costs (other than the sales load) exceeds $0.03 per share. Accordingly, the Trust's share of offering costs will be recorded as a reduction of the proceeds from the sale of its Common Shares upon the commencement of the Trust's operations. Estimated offering costs to be borne by the Trust total $689,500. Additionally, if the Trust completes an offering of Preferred Shares, the Trust will also pay expenses in connection with such offering.

2. ACCOUNTING POLICIES

The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates.

3. AGREEMENTS

The Trust has entered into an Investment Advisory Agreement with the Investment Adviser, which provides for payment of a monthly fee computed at the annual rate of 0.60% of the Trust's average weekly Total Managed Assets. Pioneer Investment Management Shareholder Services, Inc., a majority owned indirect subsidiary of UniCredito Italiano S.p.A, has contracted with the Trust to provide transfer agent and shareholder services to the Trust at negotiated rates.

36

The Investment Adviser has also entered into an Administration Agreement with the Trust pursuant to which the Investment Adviser provides certain administrative services to the Trust. Under the Administration Agreement, the Trust will reimburse the Investment Adviser for its cost of providing administrative services to the Trust, excluding the sub-administrative fee described below. The Investment Adviser has entered into an Administration Agreement with Princeton Administrators, L.P. (the "Administrator"). The Investment Adviser will pay the Administrator a monthly fee computed at the annual rate of 0.10% of the Trust's average weekly Total Managed Assets, subject to a monthly minimum fee of $10,000. "Total Managed Assets" means the total assets of the Trust (including any assets attributable to leverage) minus accrued liabilities (other than liabilities representing leverage). For purposes of calculating "Total Managed Assets," the liquidation preference of any preferred shares outstanding is not considered a liability.

4. FEDERAL INCOME TAXES

The Trust intends to qualify as a "regulated investment company" and to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, such that it will not be subject to Federal income tax on taxable income (including realized capital gains) that is distributed to shareholders.

We have audited the accompanying statement of assets and liabilities of Pioneer High Income Trust (the "Fund") as of April 22, 2002 and the related statement of operations for the period from March 18, 2002 (date of capitalization) through April 22, 2002. These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above presents fairly, in all material respects, the financial position of Pioneer High Income Trust at April 22, 2002, and the results of its operations for the period from March 18, 2002 (date of capitalization) through April 22, 2002, in conformity with accounting principles generally accepted in the United States.

APPENDIX A - DESCRIPTION OF RATINGS1

MOODY'S PRIME RATING SYSTEM

Moody's short-term ratings are opinions of the ability of issuers to honor senior financial obligations and contracts. Such obligations generally have an original maturity not exceeding one year, unless explicitly noted.

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

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

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

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

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

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

In addition, in certain countries the prime rating may be modified by the issuer's or guarantor's senior unsecured long-term debt rating.

MOODY'S DEBT RATINGS

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

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


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

A-1

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

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

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

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

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

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

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

Moody's assigns ratings to individual debt securities issued from medium-term note (MTN) programs, in addition to indicating ratings to MTN programs themselves. Notes issued under MTN programs with such indicated ratings are rated at issuance at the rating applicable to all pari passu notes issued under the same program, at the program's relevant indicated rating, provided such notes do not exhibit any of the characteristics listed below. For notes with any of the following characteristics, the rating of the individual note may differ from the indicated rating of the program:

1) Notes containing features which link the cash flow and/or market value to the credit performance of any third party or parties.
2) Notes allowing for negative coupons, or negative principal.
3) Notes containing any provision which could obligate the investor to make any additional payments.

Market participants must determine whether any particular note is rated, and if so, at what rating level.

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

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

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

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

A-2

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

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

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

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

STANDARD & POOR'S LONG-TERM ISSUE CREDIT RATINGS

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

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

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

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

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

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

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

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

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

A-3

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

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

CC: An obligation rated CC is currently highly vulnerable to nonpayment.

C: A subordinated debt or preferred stock obligation rated C is CURRENTLY HIGHLY VULNERABLE to nonpayment. The C rating may be used to cover a situation where a bankruptcy petition has been filed or similar action taken, but payments on this obligation are being continued. A C also will be assigned to a preferred stock issue in arrears on dividends or sinking fund payments, but that is currently paying.

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

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

r: This symbol is attached to the ratings of instruments with significant noncredit risks. It highlights risks to principal or volatility of expected returns which are not addressed in the credit rating.

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

LOCAL CURRENCY AND FOREIGN CURRENCY RISKS

Country risk considerations are a standard part of Standard & Poor's analysis for credit ratings on any issuer or issue. Currency of repayment is a key factor in this analysis. An obligor's capacity to repay foreign currency obligations may be lower than its capacity to repay obligations in its local currency due to the sovereign government's own relatively lower capacity to repay external versus domestic debt. These sovereign risk considerations are incorporated in the debt ratings assigned to specific issues. Foreign currency issuer ratings are also distinguished from local currency issuer ratings to identify those instances where sovereign risks make them different for the same issuer.

ITEM 29. INDEMNIFICATION

The Registrant's Agreement and Declaration of Trust (the "Declaration"), dated January 30, 2002, provides that every person who is, or has been, a Trustee or an officer, employee or agent of the Registrant (including any individual who serves at its request as director, officer, partner, trustee or the like of another organization in which it has any interest as a shareholder, creditor or otherwise) ("Covered Person") shall be indemnified by the Registrant or the appropriate series of the Registrant to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been a Covered Person and against amounts paid or incurred by him in the settlement thereof; provided that no indemnification shall be provided to a Covered Person (i) who shall have been adjudicated by a court or body before which the proceeding was brought (A) to be liable to the Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office, or (B) not to have acted in good faith in the reasonable belief that his action was in the best interest of the Registrant; or (ii) in the event of a settlement, unless there has been a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

The Declaration also provides that if any shareholder or former shareholder of any series of the Registrant shall be held personally liable solely by reason of his being or having been a shareholder and not because of his acts or omissions or for some other reason, the shareholder or former shareholder (or his heirs, executors, administrators or other legal representatives or in the case of any entity, its general successor) shall be entitled out of the assets belonging to the applicable series of the Registrant to be held harmless from and indemnified against all loss and expense arising from

C-2

such liability. The Registrant, on behalf of its affected series, shall, upon request by such shareholder, assume the defense of any claim made against such shareholder for any act or obligation of the series and satisfy any judgment thereon from the assets of the series.

Insofar as indemnification for liability arising under the Securities Act of 1933, as amended (the "1933 Act"), may be available to Trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant's expenses incurred or paid by a Trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.

No one dealing with the Trustees shall be under any obligation to make any inquiry concerning the authority of the Trustees, or to see to the application of any payments made or property transferred to the Trustees or upon their order. In construing this Declaration, the presumption shall be in favor of a grant of power to the Trustees.

Section 3. CERTAIN TRANSACTIONS. Except as prohibited by applicable law, the Trustees may, on behalf of the Trust, buy any securities from or sell any securities to, or lend any assets of the Trust to, any Trustee or officer of the Trust or any firm of which any such Trustee or officer is a member acting as principal, or have any such dealings with any investment adviser, administrator, distributor or transfer agent for the Trust or with any Interested Person of such person. The Trust may employ any such person or entity in which such person is an Interested Person, as broker, legal counsel, registrar, investment adviser, administrator, distributor, transfer agent, dividend disbursing agent, custodian or in any other capacity upon customary terms.

Section 4. INITIAL TRUSTEE(S); ELECTION AND NUMBER OF TRUSTEES. The initial Trustee(s) shall be the persons initially signing this Declaration. The number of Trustees (other than the initial Trustees) shall be fixed from time to time by a majority of the Trustees then in office; provided, that there shall be at least one (1) Trustee and no more than fifteen (15).

Section 5. TERM OF OFFICE OF TRUSTEES; CLASSES.

(a) Subject to the voting rights established with respect to a particular Series or Class, each Trustee shall hold office for life or until his successor is elected or the Trust terminates. Notwithstanding the foregoing but subject to the voting rights established with respect to a particular Series or Class, (1) any Trustee may resign by delivering to the other Trustees or to any Trust officer a written resignation effective upon such delivery or a later date specified therein; (2) any Trustee may be removed with cause at any time by a written instrument signed by at least three-quarters of the then Trustees, specifying the effective date of removal; (3) any Trustee who requests to be retired, or who is declared bankrupt or has become physically or mentally incapacitated or is otherwise unable to serve, may be retired by a written instrument signed by a majority of the other Trustees, specifying the effective date of retirement; and (4) any Trustee may be removed, with or without cause, by a vote of at least a majority of the then Trustees if such removal is approved by the holders of at least three-quarters of the Outstanding Shares entitled to vote with respect to the election of such Trustee and present in person or by proxy at a meeting of the Shareholders called for such purpose.

(b) The Board of Trustees shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of trustees constituting the entire Board of Trustees. Within the limits above specified, the number of the Trustees in each class shall be determined by resolution of the Board of Trustees. The Trustees may also determine by resolution those Trustees in each Class that shall be elected by Shareholders of a particular class of Shares (e.g., by a class of preferred Shares). The term of office of the 1st class shall expire on the date of the 1st annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement relating to the Shares under the Securities Act. The term of the 2nd class shall expire on the date of the 2nd annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement relating to the Shares under the Securities Act. The term of the 3rd class shall expire on the date of the 3rd annual meeting of Shareholders or special meeting in lieu thereof following the effective date of the Registration Statement relating to the Shares under the Securities Act. Upon expiration of the term of office of each class as set forth above, the number of Trustees in such class, as determined by the Board of Trustees, shall be elected for a term expiring on the date of the 3rd annual meeting of Shareholders or special meeting in lieu thereof following such expiration to succeed the Trustees whose terms of office expire. The Trustees shall be elected at an annual meeting of the Shareholders or special meeting in lieu thereof called for that purpose.

Section 6. VACANCIES; APPOINTMENT OF TRUSTEES. Whenever a vacancy shall exist in the Board of Trustees, regardless of the reason for such vacancy, the remaining Trustees shall appoint any person as they determine in their sole discretion to fill that vacancy, consistent with the limitations under the 1940 Act, provided, that if the Shareholders of any Class or Series of Shares are entitled separately to elect one or more Trustees, a majority of the remaining Trustees or the sole remaining Trustee elected by that Class or Series may fill any vacancy among the number of Trustees elected by that Class or Series. Such appointment shall be made by a written instrument signed by a majority of the Trustees or by a resolution of the Trustees, duly adopted and recorded in the records of the Trust, specifying the effective date of the appointment. The Trustees may appoint a new Trustee as provided above in anticipation of a vacancy expected to occur because of the retirement, resignation or removal of a Trustee, or an increase in number of Trustees, provided that such appointment shall become effective only at or after the expected vacancy occurs. As soon as any such Trustee has accepted his appointment in writing, the trust estate shall vest in the new Trustee, together with the continuing Trustees, without any further act or conveyance, and he shall be deemed a Trustee hereunder. The Trustees' power of appointment is subject to Section 16(a) of the 1940 Act. Whenever a vacancy in the number of Trustees shall occur, until such vacancy is filled as provided in this Article II, the Trustees in office, regardless of their number, shall have all the powers granted to the Trustees and shall discharge all the duties imposed upon the Trustees by the Declaration. The death, declination to serve, resignation, retirement, removal or incapacity of one or more Trustees, or all of them, shall not operate to annul the Trust or to revoke any existing agency created pursuant to the terms of this Declaration of Trust.

Section 7. TEMPORARY VACANCY OR ABSENCE. Whenever a vacancy in the Board of Trustees shall occur, until such vacancy is filled, or while any Trustee is absent from his domicile (unless that Trustee has made arrangements to be informed about, and to participate in, the affairs of the Trust during such absence), or is physically or mentally incapacitated, the remaining Trustees shall have all the powers hereunder and their certificate as to such vacancy, absence, or incapacity shall be conclusive. Any Trustee may, by power of attorney, delegate his powers as Trustee for a period not exceeding six (6) months at any one time to any other Trustee or Trustees.

Section 8. CHAIRMAN. The Trustees shall appoint one of their number to be Chairman of the Board of Trustees. The Chairman shall preside at all meetings of the Trustees, shall be responsible for the execution of policies established by the Trustees and the administration of the Trust, and may be the chief executive, financial and/or accounting officer of the Trust.

Section 9. ACTION BY THE TRUSTEES.

(a) Except as expressly provided in this Agreement, the Trustees shall act by majority vote at a meeting duly called at which a quorum is present, including a meeting held by conference telephone, teleconference or other electronic media or communication equipment by means of which all persons participating in the meeting can communicate with each other; or by written consent of a majority of Trustees (or such greater number as may be required by applicable law) without a meeting. A majority of the Trustees shall constitute a quorum at any meeting. Meetings of the Trustees may be called orally or in writing by the President or by any one of the Trustees. Notice of the time, date and place of all Trustees' meetings shall be given to each Trustee as set forth in the By-laws; provided, however, that no notice is required if the Trustees provide for regular or stated meetings. Notice need not be given to any Trustee who attends the meeting without objecting to the lack of notice or who signs a waiver of notice either before or after the meeting. Except as expressly provided in this Agreement, the Trustees by majority vote may delegate to any Trustee or Trustees or committee authority to approve particular matters or take particular actions on behalf of the Trust. Any written consent or waiver may be provided and delivered to the Trust by facsimile or other similar electronic mechanism.

(b) A Trustee who with respect to the Trust is not an Interested Person shall be deemed to be independent and disinterested when making any determinations or taking any action as a Trustee, whether pursuant to the 1940 Act, the Delaware Act or otherwise.

Section 10. OWNERSHIP OF TRUST PROPERTY. The Trust Property of the Trust and of each Series shall be held separate and apart from any assets now or hereafter held in any capacity other than as Trustee hereunder by the Trustees or any successor Trustees. Legal title in and beneficial ownership of all of the assets of the Trust shall at all times be considered as vested in the Trust, except that the Trustees may cause legal title in and beneficial ownership of any Trust Property to be held by, or in the name of one or more of the Trustees acting for and on behalf of the Trust, or in the name of any person as nominee acting for and on behalf of the Trust. No Shareholder shall be deemed to have a severable ownership in any individual asset of the Trust or of any Series or any right of partition or possession thereof, but each Shareholder shall have, as provided in Article V, a proportionate undivided beneficial interest in the Trust or Series or Class thereof represented by Shares. The Shares shall be personal property giving only the rights specifically set forth in this Trust Instrument. The Trust, or at the determination of the Trustees one or more of the Trustees or a nominee acting for and on behalf of the Trust, shall be deemed to hold legal title and beneficial ownership of any income earned on securities of the Trust issued by any business entities formed, organized, or existing under the laws of any jurisdiction, including the laws of any foreign country. Upon the resignation or removal of a Trustee, or his otherwise ceasing to be a Trustee, he shall execute and deliver such documents as the remaining Trustees shall require for the purpose of conveying to the Trust or the remaining Trustees any Trust Property held in the name of the resigning or removed Trustee. Upon the incapacity or death of any Trustee, his legal representative shall execute and deliver on his behalf such documents as the remaining Trustees shall require as provided in the preceding sentence.

Section 11. EFFECT OF TRUSTEES NOT SERVING. The death, resignation, retirement, removal, incapacity or inability or refusal to serve of the Trustees, or any one of them, shall not operate to annul the Trust or to revoke any existing agency created pursuant to the terms of this Declaration.

Section 12. TRUSTEES, ETC. AS SHAREHOLDERS. Subject to any restrictions in the By-laws, any Trustee, officer, agent or independent contractor of the Trust may acquire, own and dispose of Shares to the same extent as any other Shareholder; the Trustees may issue and sell Shares to and buy Shares from any such person or any firm or company in which such person is interested, subject only to any general limitations herein.

Section 13. SERIES TRUSTEES. In connection with the establishment of one or more Series or Classes, the Trustees establishing such Series or Class may appoint, to the extent permitted by the Delaware Act, separate Trustees with respect to such Series or Classes (the "Series Trustees"). Series Trustees may, but are not required to, serve as Trustees of the Trust or any other Series or Class of the Trust. The Series Trustees shall have, to the exclusion of any other Trustee of the Trust, all the powers and authorities of Trustees hereunder with respect to such Series or Class, but shall have no power or authority with respect to any other Series or Class. Any provision of this Declaration relating to election of Trustees by Shareholders only shall entitle the Shareholders of a Series or Class for which Series Trustees have been appointed to vote with respect to the election of such Series Trustees and the Shareholders of any other Series or Class shall not be entitled to participate in such vote. In the event that Series Trustees are appointed, the Trustees initially appointing such Series Trustees shall, without the approval of any Outstanding Shares, amend either the Declaration or the By-laws to provide for the respective responsibilities of the Trustees and the Series Trustees in circumstances where an action of the Trustees or Series Trustees affects all Series of the Trust or two or more Series represented by different Trustees.

ARTICLE III

CONTRACTS WITH SERVICE PROVIDERS

Section 1. UNDERWRITING CONTRACT. The Trustees may in their discretion from time to time enter into an exclusive or non-exclusive underwriting or distribution contract or contracts providing for the sale of the Shares whereby the Trustees may either agree to sell the Shares to the other party to the contract or appoint such other party as their sales agent for the Shares, and in either case on such terms and conditions, if any, as may be prescribed in the By-laws, and such further terms and conditions as the Trustees may in their discretion determine not inconsistent with the provisions of this Article III or of the By-laws; and such contract may also provide for the repurchase of the Shares by such other party as agent of the Trustees.

Section 2. ADVISORY OR MANAGEMENT CONTRACT. The Trustees may in their discretion from time to time enter into one or more investment advisory or management contracts or, if the Trustees establish multiple Series, separate investment advisory or management contracts with respect to one or more Series whereby the other party or parties to any such contracts shall undertake to furnish the Trust or such Series management, investment advisory, administration, accounting, legal, statistical and research facilities and services, promotional or marketing activities, and such other facilities and services, if any, as the Trustees shall from time to time consider desirable and all upon such terms and conditions as the Trustees may in their discretion determine. Notwithstanding any provisions of the Declaration, the Trustees may authorize the Investment Advisers or persons to whom the Investment Adviser delegates certain or all of their duties, or any of them, under any such contracts (subject to such general or specific instructions as the Trustees may from time to time adopt) to effect purchases, sales, loans or exchanges of portfolio securities and other investments of the Trust on behalf of the Trustees or may authorize any officer, employee or Trustee to effect such purchases, sales, loans or exchanges pursuant to recommendations of such Investment Advisers, or any of them (and all without further action by the Trustees). Any such purchases, sales, loans and exchanges shall be deemed to have been authorized by all of the Trustees.

Section 3. ADMINISTRATION AGREEMENT. The Trustees may in their discretion from time to time enter into an administration agreement or, if the Trustees establish multiple Series or Classes, separate administration agreements with respect to each Series or Class, whereby the other party to such agreement shall undertake to manage the business affairs of the Trust or of a Series or Class thereof of the Trust and furnish the Trust or a Series or a Class thereof with office facilities, and shall be responsible for the ordinary clerical, bookkeeping and recordkeeping services at such office facilities, and other facilities and services, if any, and all upon such terms and conditions as the Trustees may in their discretion determine.

Section 4. SERVICE AGREEMENT. The Trustees may in their discretion from time to time enter into service agreements with respect to one or more Series or Classes of Shares whereby the other parties to such Service Agreements will provide administration and/or support services pursuant to administration plans and service plans, and all upon such terms and conditions as the Trustees in their discretion may determine.

Section 5. TRANSFER AGENT. The Trustees may in their discretion from time to time enter into a transfer agency and shareholder service contract whereby the other party to such contract shall undertake to furnish transfer agency and shareholder services to the Trust. The contract shall have such terms and conditions as the Trustees may in their discretion determine not inconsistent with the Declaration. Such services may be provided by one or more Persons.

Section 6. CUSTODIAN. The Trustees may appoint or otherwise engage one or more banks or trust companies, each having aggregate capital, surplus and undivided profits (as shown in its last published report) of at least two million dollars ($2,000,000), or any other entity satisfying the requirements of the 1940 Act, to serve as Custodian with authority as its agent, but subject to such restrictions, limitations and other requirements, if any, as may be contained in the By-laws of the Trust. The Trustees may also authorize the Custodian to employ one or more sub-custodians, including such foreign banks and securities depositories as meet the requirements of applicable provisions of the 1940 Act, and upon such terms and conditions as may be agreed upon between the Custodian and such sub-custodian, to hold securities and other assets of the Trust and to perform the acts and services of the Custodian, subject to applicable provisions of law and resolutions adopted by the Trustees.

Section 7. AFFILIATIONS OF TRUSTEES OR OFFICERS, ETC. The fact that:

(i) any of the Shareholders, Trustees or officers of the Trust or any Series thereof is a shareholder, director, officer, partner, trustee, employee, manager, adviser or distributor of or for any partnership, corporation, trust, association or other organization or of or for any parent or affiliate of any organization, with which a contract of the character described in this Article III or for services as Custodian, Transfer Agent or disbursing agent or for related services may have been or may hereafter be made, or that any such organization, or any parent or affiliate thereof, is a Shareholder of or has an interest in the Trust, or that

(ii) any partnership, corporation, trust, association or other organization with which a contract of the character described in Sections 1, 2, 3 or 4 of this Article III or for services as Custodian, Transfer Agent or disbursing agent or for related services may have been or may hereafter be made also has any one or more of such contracts with one or more other partnerships, corporations, trusts, associations or other organizations, or has other business or interests,

shall not affect the validity of any such contract or disqualify any Shareholder, Trustee or officer of the Trust from voting upon or executing the same or create any liability or accountability to the Trust or its Shareholders.

ARTICLE IV

COMPENSATION, LIMITATION OF LIABILITY AND INDEMNIFICATION

Section 1. COMPENSATION. The Trustees as such shall be entitled to reasonable compensation from the Trust, and they may fix the amount of such compensation. Nothing herein shall in any way prevent the employment of any Trustee for advisory, management, legal, accounting, investment banking or other services and payment for the same by the Trust.

Section 2. LIMITATION OF LIABILITY. All persons contracting with or having any claim against the Trust or a particular Series shall look only to the assets of all Series or such particular Series for payment under such contract or claim; and neither the Trustees nor, when acting in such capacity, any of the Trust's officers, employees or agents, whether past, present or future, shall be personally liable therefor. Every written instrument or obligation on behalf of the Trust or any Series shall contain a statement to the foregoing effect, but the absence of such statement shall not operate to make any Trustee or officer of the Trust liable thereunder. Provided they have exercised reasonable care and have acted under the reasonable belief that their actions are in the best interest of the Trust, the Trustees and officers of the Trust shall not be responsible or liable for any act or omission or for neglect or wrongdoing of them or any officer, agent, employee, investment adviser or independent contractor of the Trust, but nothing contained in this Declaration or in the Delaware Act shall protect any Trustee or officer of the Trust against liability to the Trust or to Shareholders to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

Section 3. INDEMNIFICATION.

(a) Subject to the exceptions and limitations contained in subsection (b) below:

(i) every person who is, or has been, a Trustee or an officer, employee or agent of the Trust (including any individual who serves at its request as director, officer, partner, trustee or the like of another organization in which it has any interest as a shareholder, creditor or otherwise) ("Covered Person") shall be indemnified by the Trust or the appropriate Series to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been a Covered Person and against amounts paid or incurred by him in the settlement thereof; and

(ii) as used herein, the words "claim," "action," "suit," or "proceeding" shall apply to all claims, actions, suits or proceedings (civil, criminal or other, including appeals), actual or threatened, and the words "liability" and "expenses" shall include, without limitation, attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

(b) No indemnification shall be provided hereunder to a Covered Person:

(i) who shall have been adjudicated by a court or body before which the proceeding was brought (A) to be liable to the Trust or its Shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office, or (B) not to have acted in good faith in the reasonable belief that his action was in the best interest of the Trust; or

(ii) in the event of a settlement, unless there has been a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office; (A) by the court or other body approving the settlement; (B) by at least a majority of those Trustees who are neither Interested Persons of the Trust nor are parties to the matter based upon a review of readily available facts (as opposed to a full trial-type inquiry); (C) by written opinion of independent legal counsel based upon a review of readily available facts (as opposed to a full trial-type inquiry) or (D) by a vote of a majority of the Outstanding Shares entitled to vote (excluding any Outstanding Shares owned of record or beneficially by such individual).

(c) The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not be exclusive of or affect any other rights to which any Covered Person may now or hereafter be entitled, and shall inure to the benefit of the heirs, executors and administrators of a Covered Person.

(d) To the maximum extent permitted by applicable law, expenses in connection with the preparation and presentation of a defense to any claim, action, suit or proceeding of the character described in subsection (a) of this Section may be paid by the Trust or applicable Series from time to time prior to final disposition thereof upon receipt of an undertaking by or on behalf of such Covered Person that such amount will be paid over by him to the Trust or applicable Series if it is ultimately determined that he is not entitled to indemnification under this Section; provided, however, that either (i) such Covered Person shall have provided appropriate security for such undertaking,
(ii) the Trust is insured against losses arising out of any such advance payments or (iii) either a majority of the Trustees who are neither Interested Persons of the Trust nor parties to the matter, or independent legal counsel in a written opinion, shall have determined, based upon a review of readily available facts (as opposed to a full trial-type inquiry) that there is reason to believe that such Covered Person will not be disqualified from indemnification under this Section.

(e) Any repeal or modification of this Article IV by the Shareholders, or adoption or modification of any other provision of the Declaration or By-laws inconsistent with this Article, shall be prospective only, to the extent that such repeal, or modification would, if applied retrospectively, adversely affect any limitation on the liability of any Covered Person or indemnification available to any Covered Person with respect to any act or omission which occurred prior to such repeal, modification or adoption. Any such repeal or modification by the Shareholders shall require a vote of at least two-thirds of the Outstanding Shares entitled to vote and present in person or by proxy at any meeting of the Shareholders.

Section 4. INDEMNIFICATION OF SHAREHOLDERS. If any Shareholder or former Shareholder of any Series shall be held personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or in the case of any entity, its general successor) shall be entitled out of the assets belonging to the applicable Series to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust, on behalf of the affected Series, shall, upon request by such Shareholder, assume the defense of any claim made against such Shareholder for any act or obligation of the Series and satisfy any judgment thereon from the assets of the Series.

Section 5. NO BOND REQUIRED OF TRUSTEES. No Trustee shall be obligated to give any bond or other security for the performance of any of his duties hereunder.

Section 6. NO DUTY OF INVESTIGATION; NOTICE IN TRUST INSTRUMENTS, ETC. No purchaser, lender, transfer agent or other Person dealing with the Trustees or any officer, employee or agent of the Trust or a Series thereof shall be bound to make any inquiry concerning the validity of any transaction purporting to be made by the Trustees or by said officer, employee or agent or be liable for the application of money or property paid, loaned, or delivered to or on the order of the Trustees or of said officer, employee or agent. Every obligation, contract, instrument, certificate, Share, other security of the Trust or a Series thereof or undertaking, and every other act or thing whatsoever executed in connection with the Trust shall be conclusively presumed to have been executed or done by the executors thereof only in their capacity as Trustees under this Declaration or in their capacity as officers, employees or agents of the Trust or a Series thereof. Every written obligation, contract, instrument, certificate, Share, other security of the Trust or a Series thereof or undertaking made or issued by the Trustees may recite that the same is executed or made by them not individually, but as Trustees under the Declaration, and that the obligations of the Trust or a Series thereof under any such instrument are not binding upon any of the Trustees or Shareholders individually, but bind only the Trust Property or the Trust Property of the applicable Series, and may contain any further recital which they may deem appropriate, but the omission of such recital shall not operate to bind the Trustees individually. The Trustees shall at all times maintain insurance for the protection of the Trust Property or the Trust Property of the applicable Series, its Shareholders, Trustees, officers, employees and agents in such amount as the Trustees shall deem adequate to cover possible tort liability, and such other insurance as the Trustees in their sole judgment shall deem advisable.

Section 7. RELIANCE ON EXPERTS, ETC. Each Trustee, officer or employee of the Trust or a Series thereof shall, in the performance of his duties, powers and discretions hereunder be fully and completely justified and protected with regard to any act or any failure to act resulting from reliance in good faith upon the books of account or other records of the Trust or a Series thereof, upon an opinion of counsel, or upon reports made to the Trust or a Series thereof by any of its officers or employees or by the Investment Adviser, the Administrator, the Distributor, Transfer Agent, selected dealers, accountants, appraisers or other experts or consultants selected with reasonable care by the Trustees, officers or employees of the Trust, regardless of whether such counsel or expert may also be a Trustee.

ARTICLE V

SERIES; CLASSES; SHARES; OTHER SECURITIES

Section 1. ESTABLISHMENT OF SERIES OR CLASS. The Trust shall consist of one or more Series. Without limiting the authority of the Trustees to establish and designate any further Series or Classes, the Trustees hereby establish a single Series, designated Pioneer High Income Trust, and one Class of Shares, designated as the common shares. Each additional Series shall be established and is effective upon the adoption of a resolution of a majority of the Trustees or any alternative date specified in such resolution. The Trustees may designate the relative rights and preferences of the Shares of each Series. The Trustees may divide the Shares of any Series into Classes. Any Shares of any further Series and Classes that may from time to time be established and designated by the Trustees shall be established and designated, and the variations in the relative rights and preferences as between the different Series shall be fixed and determined, by the Trustees; provided, that all Shares shall be identical except for such variations as shall be fixed and determined between different Series or Classes by the Trustees in establishing and designating such Class or Series. Unless otherwise designated by the Trustees in the By-laws or resolutions establishing a Class, the purchase price, the method of determining the net asset value, and the relative liquidation, voting, dividend and other rights and preferences of holders of a Class shall be as set forth in the Trust's Registration Statement on Form N-2 under the Securities Act of 1933 and/or the 1940 Act relating to the issuance of Shares of such Class. To the extent that the Trustees authorized and issue preferred Shares of any Class or Series, they are hereby authorized and empowered to amend or supplement this Declaration, including an amendment or modification to the rights of any Shares outstanding at the time of such amendment or supplement, as they deem necessary or appropriate, including to comply with the requirements of the 1940 Act or requirements imposed by the rating agencies or other Persons, all without the approval of Shareholders. Any such supplement or amendment shall be filed as is necessary. The Trustees are also authorized to take such actions and retain such persons as they see fit to offer and sell such securities.

All references to Shares in this Declaration shall be deemed to be Shares of any or all Series or Classes as the context may require. The Trust shall maintain separate and distinct records for each Series and hold and account for the assets thereof separately from the other assets of the Trust or of any other Series. A Series may issue any number of Shares or any Class thereof and need not issue Shares. Except as otherwise provided with respect to a specific Class, each Share of a Series shall represent an equal beneficial interest in the net assets of such Series. Each holder of Shares of a Series or a Class thereof shall be entitled to receive his pro rata share of all distributions made with respect to such Series or Class. Upon redemption of his Shares, such Shareholder shall be paid solely out of the funds and property of such Series. The Trustees may adopt and change the name of any Series or Class.

Section 2. SHARES. The beneficial interest in the Trust shall be divided into transferable Shares of one or more separate and distinct Series or Classes established by the Trustees. The number of Shares of each Series and Class is unlimited and each Share shall have no par value per Share or such other amount as the Trustees may establish. All Shares issued hereunder shall be fully paid and nonassessable. Shareholders shall have no preemptive or other right to subscribe to any additional Shares or other securities issued by the Trust. The Trustees shall have full power and authority, in their sole discretion and without obtaining Shareholder approval, to issue original or additional Shares at such times and on such terms and conditions as they deem appropriate; to issue fractional Shares and Shares held in the treasury; to establish and to change in any manner Shares of any Series or Classes with such preferences, rights upon liquidation, redemption rights, terms of conversion, voting powers, and other rights and privileges as the Trustees may determine (but the Trustees may not change Outstanding Shares in a manner materially adverse to the Shareholders of such Shares); to divide or combine the Shares of any Series or Classes into a greater or lesser number; to classify or reclassify any unissued Shares of any Series or Classes into one or more Series or Classes of Shares; to abolish any one or more Series or Classes of Shares; to issue Shares to acquire other assets (including assets subject to, and in connection with, the assumption of liabilities) and businesses; and to take such other action with respect to the Shares as the Trustees may deem desirable. Shares held in the treasury shall not confer any voting rights on the Trustees and shall not be entitled to any dividends or other distributions declared with respect to the Shares.

Section 3. INVESTMENT IN THE TRUST. The Trustees shall accept investments in any Series or Class from such persons and on such terms as they may from time to time authorize. At the Trustees' discretion, such investments, subject to applicable law, may be in the form of cash or securities in which that Series is authorized to invest, valued as provided in Article VI, Section 3. Investments in a Series shall be credited to each Shareholder's account in the form of full Shares at the Net Asset Value per Share next determined after the investment is received or accepted as may be determined by the Trustees; provided, however, that the Trustees may, in their sole discretion, (a) impose a sales charge upon investments in any Series or Class, (b) issue fractional Shares, (c) determine the Net Asset Value per Share of the initial capital contribution or (d) authorize the issuance of Shares at a price other than Net Asset Value to the extent permitted by the 1940 Act or any rule, order or interpretation of the Commission thereunder. The Trustees shall have the right to refuse to accept investments in any Series at any time without any cause or reason therefor whatsoever.

Section 4. ASSETS AND LIABILITIES OF SERIES. All consideration received by the Trust for the issue or sale of Shares of a particular Series, together with all assets in which such consideration is invested or reinvested, all income, earnings, profits, and proceeds thereof (including any proceeds derived from the sale, exchange or liquidation of such assets, and any funds or payments derived from any reinvestment of such proceeds in whatever form the same may be), shall be held and accounted for separately from the assets of every other Series and are referred to as "assets belonging to" that Series. The assets belonging to a Series shall belong only to that Series for all purposes, and to no other Series, subject only to the rights of creditors of that Series. Any assets, income, earnings, profits, and proceeds thereof, funds, or payments which are not readily identifiable as belonging to any particular Series shall be allocated by the Trustees between and among one or more Series as the Trustees deem fair and equitable. Each such allocation shall be conclusive and binding upon the Shareholders of all Series for all purposes, and such assets, earnings, income, profits or funds, or payments and proceeds thereof shall be referred to as assets belonging to that Series. The assets belonging to a Series shall be so recorded upon the books of the Trust, and shall be held by the Trustees in trust for the benefit of the Shareholders of that Series. The assets belonging to a Series shall be charged with the liabilities of that Series and all expenses, costs, charges and reserves attributable to that Series, except that liabilities and expenses allocated solely to a particular Class shall be borne by that Class. Any general liabilities, expenses, costs, charges or reserves of the Trust which are not readily identifiable as belonging to any particular Series or Class shall be allocated and charged by the Trustees between or among any one or more of the Series or Classes in such manner as the Trustees deem fair and equitable. Each such allocation shall be conclusive and binding upon the Shareholders of all Series or Classes for all purposes.

Without limiting the foregoing, but subject to the right of the Trustees to allocate general liabilities, expenses, costs, charges or reserves as herein provided, the debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to a particular Series shall be enforceable against the assets of such Series only, and not against the assets of any other Series. Notice of this contractual limitation on liabilities among Series may, in the Trustees' discretion, be set forth in the certificate of trust of the Trust (whether originally or by amendment) as filed or to be filed in the Office of the Secretary of State of the State of Delaware pursuant to the Delaware Act, and upon the giving of such notice in the certificate of trust, the statutory provisions of Section 3804 of the Delaware Act relating to limitations on liabilities among Series (and the statutory effect under Section 3804 of setting forth such notice in the certificate of trust) shall become applicable to the Trust and each Series. Any person extending credit to, contracting with or having any claim against any Series may look only to the assets of that Series to satisfy or enforce any debt, with respect to that Series. No Shareholder or former Shareholder of any Series shall have a claim on or any right to any assets allocated or belonging to any other Series.

Section 5. OWNERSHIP AND TRANSFER OF SHARES. The Trust or a transfer or similar agent for the Trust shall maintain a register containing the names and addresses of the Shareholders of each Series and Class thereof, the number of Shares of each Series and Class held by such Shareholders, and a record of all Share transfers. The register shall be conclusive as to the identity of Shareholders of record and the number of Shares held by them from time to time. The Trustees may authorize the issuance of certificates representing Shares and adopt rules governing their use. The Trustees may make rules governing the transfer of Shares, whether or not represented by certificates. Except as otherwise provided by the Trustees, Shares shall be transferable on the books of the Trust only by the record holder thereof or by his duly authorized agent upon delivery to the Trustees or the Trust's transfer agent of a duly executed instrument of transfer, together with a Share certificate if one is outstanding, and such evidence or the genuineness of each such execution and authorization and of such other matters as may be required by the Trustees. Upon such delivery, and subject to any further requirements specified by the Trustees or contained in the By-laws, the transfer shall be recorded on the books of the Trust. Until a transfer is so recorded, the Shareholder of record of Shares shall be deemed to be the holder of such Shares for all purposes hereunder and neither the Trustees nor the Trust, nor any transfer agent or registrar or any officer, employee or agent of the Trust, shall be affected by any notice of a proposed transfer.

Section 6. STATUS OF SHARES; LIMITATION OF SHAREHOLDER LIABILITY. Shares shall be deemed to be personal property giving Shareholders only the rights provided in this Declaration. Every Shareholder, by virtue of having acquired a Share, shall be held expressly to have assented to and agreed to be bound by the terms of this Declaration and to have become a party hereto. No Shareholder shall be personally liable for the debts, liabilities, obligations and expenses incurred by, contracted for, or otherwise existing with respect to, the Trust or any Series. The death, incapacity, dissolution, termination or bankruptcy of a Shareholder during the existence of the Trust shall not operate to terminate the Trust, nor entitle the representative of any such Shareholder to an accounting or to take any action in court or elsewhere against the Trust or the Trustees, but entitles such representative only to the rights of such Shareholder under this Trust. Ownership of Shares shall not entitle the Shareholder to any title in or to the whole or any part of the Trust Property or right to call for a partition or division of the same or for an accounting, nor shall the ownership of Shares constitute the Shareholders as partners. Neither the Trust nor the Trustees shall have any power to bind any Shareholder personally or to demand payment from any Shareholder for anything, other than as agreed by the Shareholder. Shareholders shall have the same limitation of personal liability as is extended to shareholders of a private corporation for profit incorporated in the State of Delaware. Every written obligation of the Trust or any Series shall contain a statement to the effect that such obligation may only be enforced against the assets of the appropriate Series or all Series; however, the omission of such statement shall not operate to bind or create personal liability for any Shareholder or Trustee.

Section 7. OTHER SECURITIES. The Trustees may authorize and issue such other securities of the Trust other than Shares as they determine to be necessary, desirable or appropriate, having such terms, rights, preferences, privileges, limitations and restrictions as the Trustees see fit, including preferred interests, debt securities or other senior securities.

ARTICLE VI

DISTRIBUTIONS AND REDEMPTIONS

Section 1. DISTRIBUTIONS. The Trustees or a committee of one or more Trustees or one or more officers may declare and pay dividends and other distributions, including dividends on Shares of a particular Series or Class and other distributions from the assets belonging to that Series. No dividend or distribution, including, without limitation, any distribution paid upon termination of the Trust or of any Series (or Class) with respect to, nor any redemption or repurchase of, the Shares of any Series (or Class) shall be effected by the Trust other than from the assets held with respect to such Series, nor shall any Shareholder of any particular Series otherwise have any right or claim against the assets held with respect to any other Series except to the extent that such Shareholder has such a right or claim hereunder as a Shareholder of such other Series. The Trustees shall have full discretion to determine which items shall be treated as income and which items as capital; and each such determination and allocation shall be conclusive and binding upon the Shareholders. The amount and payment of dividends or distributions and their form, whether they are in cash, Shares or other Trust Property, shall be determined by the Trustees. Dividends and other distributions may be paid pursuant to a standing resolution adopted once or more often as the Trustees determine. Except as provided with respect to a particular Class in the By-laws or the resolutions establishing such Class, all dividends and other distributions on Shares of a particular Series shall be distributed pro rata to the Shareholders of that Series in proportion to the number of Shares of that Series they held on the record date established for such payment. The Trustees may adopt and offer to Shareholders such dividend reinvestment plans, cash dividend payout plans or similar plans as the Trustees deem appropriate.

Section 2. REDEMPTIONS. Except as provided with respect to a particular Class in the By-laws or the resolutions establishing such Class, Shares of the Trust will not be redeemed or repurchased by the Trust, except as the Trustees shall determine from time to time and the Trust shall be under no obligation to redeem or repurchase Shares. The Trustees may specify conditions, prices, and places of redemption, may specify binding requirements for the proper form or forms of requests for redemption and may specify the amount of any deferred sales charge to be withheld from redemption proceeds. Payment of the redemption price may be wholly or partly in securities or other assets at the value of such securities or assets used in such determination of Net Asset Value, or may be in cash. Upon redemption, Shares may be reissued from time to time. The Trustees may require Shareholders to redeem Shares for any reason under terms set by the Trustees, including, but not limited to, the failure of a Shareholder to supply a taxpayer identification number if required to do so, or to have the minimum investment required, or to pay when due for the purchase of Shares issued to him. To the extent permitted by law, the Trustees may retain the proceeds of any redemption of Shares required by them for payment of amounts due and owing by a Shareholder to the Trust or any Series or Class or any governmental authority. Notwithstanding the foregoing, the Trustees may postpone payment of the redemption price and may suspend the right of the Shareholders to require any Series or Class to redeem Shares during any period of time when and to the extent permissible under the 1940 Act.

Section 3. DETERMINATION OF NET ASSET VALUE. The Trustees shall cause the Net Asset Value of Shares of each Series or Class to be determined from time to time in a manner consistent with applicable laws and regulations. The Trustees may delegate the power and duty to determine Net Asset Value per Share to one or more Trustees or officers of the Trust or to a custodian, depository or other agent appointed for such purpose. The Net Asset Value of Shares shall be determined separately for each Series or Class at such times as may be prescribed by the Trustees or, in the absence of action by the Trustees, as of the close of regular trading on the New York Stock Exchange on each day for all or part of which such Exchange is open for unrestricted trading. Section 4. SUSPENSION OF RIGHT OF REDEMPTION. If, as referred to in Section 2 of this Article, the Trustees postpone payment of the redemption price and suspend the right of Shareholders to redeem their Shares, such suspension shall take effect at the time the Trustees shall specify, but not later than the close of business on the business day next following the declaration of suspension. Thereafter Shareholders shall have no right of redemption or payment until the Trustees declare the end of the suspension. If the right of redemption is suspended, a Shareholder may either withdraw his request for redemption or receive payment based on the Net Asset Value per Share next determined after the suspension terminates.

Section 5. REPURCHASE BY AGREEMENT. The Trust may repurchase Shares directly, or through the Distributor or another agent designated for the purpose, by agreement with the owner thereof at a price not exceeding the Net Asset Value per Share determined as of the time when the purchase or contract of purchase is made or the Net Asset Value as of any time which may be later determined, provided payment is not made for the Shares prior to the time as of which such Net Asset Value is determined.

ARTICLE VII

SHAREHOLDERS' VOTING POWERS AND MEETINGS

Section 1. VOTING POWERS. Subject to the voting rights established with respect to a particular Class in the By-laws or the resolutions establishing such Class, the Shareholders shall have power to vote only with respect to (a) the election of Trustees as provided in Section 2 of this Article; (b) the removal of Trustees as provided in Article II, Section 5(b); (c) any investment advisory or management contract to the extent required by the 1940 Act; (d) the amendment of this Declaration to the extent and as provided in Article X, Section 10; (d) termination of the Trust to the extent provided in Article IX, Section 4, (f) the conversion of the Trust to an open-end investment company to the extent provided in Article IX, Section 5, (g) the reorganization of the Trust to the extent provided in Article IX, Section 6; (h) to approve a transaction subject to Article IX, Section 7, and (i) such additional matters relating to the Trust as may be required or authorized by law, this Declaration, or the By-laws or any registration of the Trust with the Commission or any State, or as the Trustees may consider desirable.

On any matter submitted to a vote of the Shareholders, all Shares shall be voted by individual Series or Class, except (a) as provided with respect to a particular Class in the By-laws or the resolutions establishing such Class, (b) when required by the 1940 Act, Shares shall be voted in the aggregate and not by individual Series or Class, and (c) when the Trustees have determined that the matter affects the interests of more than one Series or Class, then the Shareholders of all such Series or Classes shall be entitled to vote thereon. As determined by the Trustees without the vote or consent of shareholders and except as provided with respect to a particular Class in the By-laws or the resolutions establishing such Class, on any matter submitted to a vote of Shareholders either (i) each whole Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Share shall be entitled to a proportionate fractional vote or (ii) each dollar of net asset value (number of Shares owned times net asset value per share of such Series or Class, as applicable) shall be entitled to one vote on any matter on which such Shares are entitled to vote and each fractional dollar amount shall be entitled to a proportionate fractional vote. Without limiting the power of the Trustees in any way to designate otherwise in accordance with the preceding sentence, the Trustees hereby establish that each whole Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Share shall be entitled to a proportionate fractional vote. There shall be no cumulative voting in the election of Trustees. Shares may be voted in person or by proxy or in any manner provided for in the By-laws. The By-laws may provide that proxies may be given by any electronic or telecommunications device or in any other manner, but if a proposal by anyone other than the officers or Trustees is submitted to a vote of the Shareholders of any Series or Class, or if there is a proxy contest or proxy solicitation or proposal in opposition to any proposal by the officers or Trustees, Shares may be voted only in person or by written proxy. Until Shares of a Series are issued, as to that Series the Trustees may exercise all rights of Shareholders and may take any action required or permitted to be taken by Shareholders by law, this Declaration or the By-laws. Meetings of Shareholders shall be called and notice thereof and record dates therefor shall be given and set as provided in the By-laws.

Section 2. QUORUM; REQUIRED VOTE. One-third of the Outstanding Shares of each Series or Class, or one-third of the Outstanding Shares of the Trust, entitled to vote in person or by proxy shall be a quorum for the transaction of business at a Shareholders' meeting with respect to such Series or Class, or with respect to the entire Trust, respectively. Any lesser number shall be sufficient for adjournments. Any adjourned session of a Shareholders' meeting may be held within a reasonable time without further notice. Except when a larger vote is required by law, this Declaration or the By-laws, a majority of the Shares voting at a Shareholders' meeting in person or by proxy shall decide any matters to be voted upon with respect to the entire Trust and a plurality of such Shares shall elect a Trustee; provided, that if this Declaration or applicable law permits or requires that Shares be voted on any matter by individual Series or Classes, then a majority of the Shares of that Series or Class (or, if required by law, a majority of the Shares outstanding and entitled to vote of that Series or Class) voting at a Shareholders' meeting in person or by proxy on the matter shall decide that matter insofar as that Series or Class is concerned; and provide further that if this Declaration (including any terms of a class of preferred Shares) or applicable law require that the Shareholders of one or more specific Class elect one or more Trustees, such Trustees shall be elected by a plurality of the Shares of such Class.

Section 3. RECORD DATES. For the purpose of determining the Shareholders of any Series (or Class) who are entitled to receive payment of any dividend or of any other distribution, the Trustees may from time to time fix a date, which shall be before the date for the payment of such dividend or such other payment, as the record date for determining the Shareholders of such Series (or Class) having the right to receive such dividend or distribution. Without fixing a record date, the Trustees may for distribution purposes close the register or transfer books for one or more Series (or Classes) any time prior to the payment of a distribution. Nothing in this Section shall be construed as precluding the Trustees from setting different record dates for different Series (or Classes).

Section 4. ADDITIONAL PROVISIONS. The By-laws may include further provisions for Shareholders' votes and meetings and related matters.

ARTICLE VIII

EXPENSES OF THE TRUST AND SERIES

Section 1. PAYMENT OF EXPENSES BY THE TRUST. Subject to Article V, Section 4, the Trust or a particular Series shall pay, or shall reimburse the Trustees from the assets belonging to all Series or the particular Series, for their expenses (or the expenses of a Class of such Series) and disbursements, including, but not limited to, interest charges, taxes, brokerage fees and commissions; expenses of issue, repurchase and redemption of Shares; certain insurance premiums; applicable fees, interest charges and expenses of third parties, including the Trust's investment advisers, managers, administrators, distributors, custodians, transfer agents and fund accountants; fees of pricing, interest, dividend, credit and other reporting services; costs of membership in trade associations; telecommunications expenses; funds transmission expenses; auditing, legal and compliance expenses; costs of forming the Trust and its Series and maintaining its existence; costs of preparing and printing the prospectuses of the Trust and each Series, statements of additional information and Shareholder reports and delivering them to Shareholders; expenses of meetings of Shareholders and proxy solicitations therefor; costs of maintaining books and accounts; costs of reproduction, stationery and supplies; fees and expenses of the Trustees; compensation of the Trust's officers and employees and costs of other personnel performing services for the Trust or any Series; costs of Trustee meetings; Commission registration fees and related expenses; state or foreign securities laws registration fees and related expenses; and for such non-recurring items as may arise, including litigation to which the Trust or a Series (or a Trustee or officer of the Trust acting as such) is a party, and for all losses and liabilities by them incurred in administering the Trust. The Trustees shall have a lien on the assets belonging to the appropriate Series, or in the case of an expense allocable to more than one Series, on the assets of each such Series, prior to any rights or interests of the Shareholders thereto, for the reimbursement to them of such expenses, disbursements, losses and liabilities.

Section 2. PAYMENT OF EXPENSES BY SHAREHOLDERS. The Trustees shall have the power, as frequently as they may determine, to cause each Shareholder, or each Shareholder of any particular Series, to pay directly, in advance or arrears, for charges of the Trust's custodian or transfer, shareholder servicing or similar agent, an amount fixed from time to time by the Trustees, by setting off such charges due from such Shareholder from declared but unpaid dividends owed such Shareholder and/or by reducing the number of Shares in the account of such Shareholder by that number of full and/or fractional Shares which represents the outstanding amount of such charges due from such Shareholder.

ARTICLE IX

MISCELLANEOUS

Section 1. TRUST NOT A PARTNERSHIP. This Declaration creates a trust and not a partnership. No Trustee shall have any power to bind personally either the Trust's officers or any Shareholder.

Section 2. TRUSTEE ACTION. The exercise by the Trustees of their powers and discretion hereunder in good faith and with reasonable care under the circumstances then prevailing shall be binding upon everyone interested. Subject to the provisions of Article IV, the Trustees shall not be liable for errors of judgment or mistakes of fact or law.

Section 3. RECORD DATES. The Trustees may fix in advance a date up to ninety
(90) days before the date of any Shareholders' meeting, or the date for the payment of any dividends or other distributions, or the date for the allotment of rights, or the date when any change or conversion or exchange of Shares shall go into effect as a record date for the determination of the Shareholders entitled to notice of, and to vote at, any such meeting, or entitled to receive payment of such dividend or other distribution, or to receive any such allotment of rights, or to exercise such rights in respect of any such change, conversion or exchange of Shares.

Section 4. TERMINATION OF THE TRUST.

(a) This Trust shall have perpetual existence. Subject to the affirmative vote of not less than three-quarters of the Shares outstanding and entitled to vote of the Trust or of each Series to be affected, the Trustees may:

(i) sell and convey all or substantially all of the assets of all Series or any affected Series to another Series or to any other corporation, association, trust or other organization, or a series thereof, for adequate consideration, which may include the assumption of all outstanding obligations, taxes and other liabilities, accrued or contingent, of the Trust or any affected Series, and which may include shares of or interests in such Series, entity, or series thereof;

(ii) merge with or into, consolidate or exchange Shares with any other entity; or

(iii) at any time sell and convert into money all or substantially all of the assets of all Series or any affected Series.

PROVIDED, HOWEVER, if at least three-quarters of the Trustees then in office have approved the transactions in (i) or (ii) above, then such actions may be approved by the affirmative vote of a majority of the Shares outstanding and entitled to vote of the Trust or the affected Series.

Upon making reasonable provision for the payment of all known liabilities of all Series or any affected Series in either (i) or (ii), by such assumption or otherwise, the Trustees shall distribute the remaining proceeds or assets (as the case may be) ratably among the Shareholders of all Series or any affected Series; however, the payment to any particular Class of such Series may be reduced by any fees, expenses or charges allocated to that Class.

(b) Upon completion of the distribution of the remaining proceeds or assets pursuant to subsection (a), the Trust or affected Series shall terminate and the Trustees and the Trust shall be discharged of any and all further liabilities and duties hereunder with respect thereto and the right, title and interest of all parties therein shall be canceled and discharged. Upon termination of the Trust, following completion of winding up of its business, the Trustees shall cause a certificate of cancellation of the Trust's certificate of trust to be filed in accordance with the Delaware Act, which certificate of cancellation may be signed by any one Trustee.

Section 5. CONVERSION TO AN OPEN-END INVESTMENT COMPANY. Notwithstanding any other provisions of this Declaration or the By-Laws of the Trust, a favorable vote of a majority of the Trustees then in office followed by the favorable vote of the holders of not less than three-quarters of the Shares of each affected class or series outstanding, voting as separate classes or series, shall be required to approve, adopt or authorize an amendment to this Declaration that makes the Shares a "redeemable security" as that term is defined in the 1940 Act, unless such amendment has been approved by three-quarters of the Trustees, in which case approval by a vote of a majority of the Shares outstanding and entitled to vote shall be required. Upon the adoption of a proposal to convert the Trust from a "closed-end company" to an "open-end company" as those terms are defined by the 1940 Act and the necessary amendments to this Declaration to permit such a conversion of the Trust's outstanding Shares entitled to vote, the Trust shall, upon complying with any requirements of the 1940 Act and state law, become an "open-end" investment company. Such affirmative vote or consent shall be in addition to the vote or consent of the holders of the Shares otherwise required by law, or any agreement between the Trust and any national securities exchange.

Section 6. REORGANIZATION.

(a) Except as provided in clause (b) of this Section 6 or in Sections 4 or 7 of this Article IX, the Trust may merge or consolidate with any other corporation, association, trust or other organization or may sell, lease or exchange all or substantially all of the Trust Property or the property, including its good will, upon such terms and conditions and for such consideration when and as authorized by a majority of the Trustees and approved by a vote of a majority of the Shares outstanding and entitled to vote and any such merger, consolidation, sale, lease or exchange shall be determined for all purposes to have been accomplished under and pursuant to the statutes of the State of Delaware.

(b) Notwithstanding anything else herein, to change the Trust's form or place of organization the Trustees may, without Shareholder approval unless such approval is required by applicable law, (i) cause the Trust to merge or consolidate with or into one or more entities, if the surviving or resulting entity is the Trust or any other corporation, association, trust or other organization, or a series thereof, (ii) cause the Shares to be exchanged under or pursuant to any state or federal statute to the extent permitted by law, or (iii) cause the Trust to incorporate under the laws of Delaware or any other U.S. jurisdiction. Any agreement of merger or consolidation or certificate of merger may be signed by a majority of Trustees and facsimile signatures conveyed by electronic or telecommunication means shall be valid.
(c) Pursuant to and in accordance with the provisions of Section 3815(f) of the Delaware Act, an agreement of merger or consolidation approved by the Trustees, and if applicable, Shareholders in accordance with this Section 6 may effect any amendment to the Declaration or effect the adoption of a new trust instrument of the Trust if it is the surviving or resulting trust in the merger or consolidation.

(d) The Trustees may create one or more business trusts to which all or any part of the assets, liabilities, profits or losses of the Trust or any Series or Class thereof may be transferred and may provide for the conversion of Shares in the Trust or any Series or Class thereof into beneficial interests in any such newly created trust or trusts or any series or classes thereof.

Section 7. CERTAIN TRANSACTIONS.

(a) Notwithstanding any other provision of this Declaration and subject to the exceptions provided in paragraph (d) of this Section, the types of transactions described in paragraph (c) of this Section shall require the affirmative vote or consent of a majority of the Trustees then in office followed by the affirmative vote or consent of holders of not less than three-quarters of the Shares of each affected class or series outstanding, votes voting as separate classes or series, when a Principal Shareholder (as defined in paragraph (b) of this Section) is a party to the transaction. Such affirmative vote or consent shall be in addition to the vote or consent of the holders of Shares otherwise required by law or by the terms of any class or series of preferred stock, whether now or hereafter authorized, or any agreement between the Trust and any national securities exchange.

(b) The term "Principal Shareholder" shall mean any corporation, Person or other entity which is the beneficial owner, directly or indirectly, of five percent (5%) or more of the outstanding Shares of any class or series and shall include any affiliate or associates, as such terms are defined in clause (ii) below, of a Principal Shareholder. For the purpose of this Section, in addition to the Shares which a corporation, Person or other entity beneficially owns directly,
(a) any corporation, Person or other entity shall be deemed to be the beneficial owner of any Shares (i) which it has the right to acquire pursuant to any agreement or upon exercise of conversion rights or warrants, or otherwise (but excluding share options granted by the Trust) or (ii) which are beneficially owned, directly or indirectly (including Shares deemed owned through application of clause (i) above, by any other corporation, Person or entity with which its "affiliate" or "associate" (as defined below) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of Shares, of which is its "affiliate" or "associate" as those terms are defined in Rule 12b-2 of the General Rules and Regulations under the Securities Exchange Act of 1934, and (b) the outstanding Shares shall include Shares deemed owned through application of clauses (i) and (ii) above but shall not include any other Shares which may be issuable pursuant to any agreement, or upon exercise of conversion rights or warrants, or otherwise.

(c) This Section shall apply to the following transactions:

(i) The merger or consolidation of the Trust or any subsidiary of the Trust with or into any Principal Shareholder.

(ii) The issuance of any securities of the Trust to any Principal Shareholder for cash (other than pursuant to any automatic dividend reinvestment plan).

(iii) The sale, lease or exchange to the Trust or any subsidiary thereof, in exchange for securities of the Trust, of any assets of any Principal Shareholder (except assets having an aggregate fair market value of less than $1,000,000, aggregating for the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period.)

(iv) The sale, lease or exchange to the Trust or any subsidiary thereof, in exchange for securities of the Trust, of any assets of any Principal Shareholder (except assets having an aggregate fair market value of less than $1,000,000, aggregating for the purposes of such computation all assets sold, leased or exchanged in any series of similar transactions within a twelve-month period).

(d) The provisions of this Section shall not be applicable to (i) any of the transactions described in paragraph (c) of this Section if three-quarters of the Trustees shall by resolution have approved a memorandum of understanding with such Principal Shareholder with respect to and substantially consistent with such transaction, in which case approval by the vote of a majority of the Shares outstanding and entitled to vote shall be the only vote of Shareholders required by this Section, or (ii) any such transaction with any entity of which a majority of the outstanding shares of all classes and series of a stock normally entitled to vote in elections of directors is owner of record or beneficially by the Trust and its subsidiaries.

(e) The Board of Trustees shall have the power and duty to determine for the purposes of this Section on the basis of information known to the Trust whether
(i) a corporation, person or entity beneficially owns five percent (5%) or more of the outstanding Shares of any class or series, (ii) a corporation, person or entity is an "affiliate" or "associate" (as defined above) of another, (iii) the assets being acquired or leased to or by the Trust or any subsidiary thereof constitute a substantial part of the assets of the Trust and have an aggregate fair market value of less than $1,000,000, and (iv) the memorandum of understanding referred to in paragraph (d) hereof is substantially consistent with the transaction covered thereby. Any such determination shall be conclusive and binding for all purposes of this Section.

Section 8. DECLARATION OF TRUST. The original or a copy of this Declaration of Trust and of each amendment hereto or Declaration of Trust supplemental shall be kept at the office of the Trust where it may be inspected by any Shareholder. Anyone dealing with the Trust may rely on a certificate by a Trustee or an officer of the Trust as to the authenticity of the Declaration of Trust or any such amendments or supplements and as to any matters in connection with the Trust. The masculine gender herein shall include the feminine and neuter genders. Headings herein are for convenience only and shall not affect the construction of this Declaration of Trust. This Declaration of Trust may be executed in any number of counterparts, each of which shall be deemed an original.

Section 9. APPLICABLE LAW. This Declaration and the Trust created hereunder are governed by and construed and administered according to the Delaware Act and the applicable laws of the State of Delaware; provided, however, that there shall not be applicable to the Trust, the Trustees or this Declaration of Trust (a) the provisions of Section 3540 of Title 12 of the Delaware Code, or (b) any provisions of the laws (statutory or common) of the State of Delaware (other than the Delaware Act) pertaining to trusts which relate to or regulate (i) the filing with any court or governmental body or agency of trustee accounts or schedules of trustee fees and charges, (ii) affirmative requirements to post bonds for trustees, officers, agents or employees of a trust, (iii) the necessity for obtaining court or other governmental approval concerning the acquisition, holding or disposition of real or personal property, (iv) fees or other sums payable to trustees, officers, agents or employees of a trust, (v) the allocation of receipts and expenditures to income or principal, (vi) restrictions or limitations on the permissible nature, amount or concentration of trust investments or requirements relating to the titling, storage or other manner of holding of trust assets, or (vii) the establishment of fiduciary or other standards of responsibilities or limitations on the acts or powers of trustees, which are inconsistent with the limitations or liabilities or authorities and powers of the Trustees set forth or referenced in this Declaration. The Trust shall be of the type commonly called a Delaware business trust, and, without limiting the provisions hereof, the Trust may exercise all powers which are ordinarily exercised by such a trust under Delaware law. The Trust specifically reserves the right to exercise any of the powers or privileges afforded to trusts or actions that may be engaged in by trusts under the Delaware Act, and the absence of a specific reference herein to any such power, privilege or action shall not imply that the Trust may not exercise such power or privilege or take such actions.

Section 10. AMENDMENTS.

(a) The Trustees may, without any Shareholder vote, amend or otherwise supplement this Declaration by making an amendment, a Declaration of Trust supplemental hereto or an amended and restated trust instrument; provided, that Shareholders shall have the right to vote on any amendment (a) which would affect the voting rights of Shareholders granted in Article VII, Section l, (b) to this Section 10, (c) required to be approved by Shareholders by law or by the Trust's registration statement(s) filed with the Commission, and (d) submitted to them by the Trustees in their discretion. Any amendment submitted to Shareholders which the Trustees determine would affect the Shareholders of any Series shall be authorized by vote of the Shareholders of such Series and no vote shall be required of Shareholders of a Series not affected. Notwithstanding anything else herein, any amendment to Article IV which would have the effect of reducing the indemnification and other rights provided thereby to Trustees, officers, employees, and agents of the Trust or to Shareholders or former Shareholders, and any repeal or amendment of this sentence shall each require the affirmative vote of the holders of two-thirds of the Outstanding Shares of the Trust entitled to vote thereon and no such amendment shall effect the right to indemnification of any person who is no longer a Trustee, Officer or employee or agent at the time of such amendment.

(b) The Trustees may not amend this Declaration of Trust to eliminate the rights of Shareholders of any Class or Series as set forth in this Section 10(b) to vote on any amendment of this Declaration of Trust or the By-Laws or alter or amend the percentage of voting Shares required to approve any amendment or action which requires a specific Shareholder vote under this Declaration of Trust or the By-Laws unless an equivalent vote has authorized such an amendment of the Declaration of Trust or By-Laws. Any amendment (other than an amendment establishing the rights of another Class of Shares, even if the rights of such Class adversely effect the rights of any existing Class) which adversely affects the holders of one or more Classes or Series of Shares shall require a vote of the Shareholders holding a majority of the Shares of each Class or Series so adversely affected and entitled to vote thereon and no vote of Shareholders of any Class or Series not so adversely affected shall be required, except that any amendment of any provision of Article IX, Sections 4, 5, 6 or 7 shall require the vote of the Shareholders holding three-quarters of the Shares of each Class and Series entitled to vote thereon, regardless of the percentage of Trustees recommending such amendment.

Section 11. DERIVATIVE ACTIONS. In addition to the requirements set forth in
Section 3816 of the Delaware Act, a Shareholder may bring a derivative action on behalf of the Trust only if the following conditions are met:

(a) Shareholders eligible to bring such derivative action under the Delaware Act who hold at least 10% of the Outstanding Shares of the Trust, or 10% of the Outstanding Shares of the Series or Class to which such action relates, shall join in the request for the Trustees to commence such action; and

(b) the Trustees must be afforded a reasonable amount of time to consider such shareholder request and to investigate the basis of such claim. The Trustees shall be entitled to retain counsel or other advisers in considering the merits of the request and shall require an undertaking by the Shareholders making such request to reimburse the Trust for the expense of any such advisers in the event that the Trustees determine not to bring such action.

Section 12. FISCAL YEAR. The fiscal year of the Trust shall end on a specified date as set forth in the By-laws. The Trustees may change the fiscal year of the Trust without Shareholder approval.

Section 13. SEVERABILITY. The provisions of this Declaration are severable. If the Trustees determine, with the advice of counsel, that any provision hereof conflicts with the 1940 Act, the regulated investment company provisions of the Internal Revenue Code or with other applicable laws and regulations, the conflicting provision shall be deemed never to have constituted a part of this Declaration; provided, however, that such determination shall not affect any of the remaining provisions of this Declaration or render invalid or improper any action taken or omitted prior to such determination. If any provision hereof shall be held invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall attach only to such provision only in such jurisdiction and shall not affect any other provision of this Declaration.

PIONEER HIGH INCOME TRUST

AUTOMATIC DIVIDEND REINVESTMENT PLAN

TERMS AND CONDITION

Pursuant to the Automatic Dividend Reinvestment Plan (the "Plan") of Pioneer High Income Trust (the "Trust"), unless a holder (each, a "Shareholder") of the Trust's common shares of beneficial interest (the "Common Shares") otherwise elects, all dividends and capital gain distributions on such Shareholder's Common Shares will be automatically reinvested by Mellon Investor Services , as agent for Shareholders in administering the Plan (the "Plan Agent"), in additional Common Shares of the Trust. Shareholders who elect not to participate in the Plan will receive all dividends and other distributions payable in cash paid by check mailed directly to the Shareholder of record (or, if the Common Shares are held in street or other nominee name, then to such nominee) by Mellon Investor Services , as the Dividend Disbursing Agent. Shareholders may elect not to participate in the Plan and to receive all dividends and capital gain distributions in cash by contacting the Plan Agent. Enrollment, purchase or sales of shares and other transactions or services offered by the Plan can be directed to the Plan Agent through the following:

IN WRITING

You may also write to the Plan Agent at the following address: Mellon Investor Services, P.O. Box 3338, South Hackensack, NJ 07606-1938. Be sure to include your name, address, daytime phone number, social security or tax I.D. number and a reference to Pioneer High Income Trust on all correspondence. .

Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notice if received by the Plan Agent prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution.

The Plan Agent will open an account for each Shareholder under the Plan in the same name in which such Shareholder's Common Shares are registered. Whenever the Trust declares an income dividend or a capital gain distribution (collectively referred to as "dividends") payable in cash, non-participants in the Plan will receive cash and participants in the Plan will receive the equivalent in Common Shares. The Common Shares will be acquired by the Plan Agent for the participants' accounts, depending upon the circumstances described below, either (i) through receipt of additional unissued but authorized Common Shares from the Trust ("newly issued Common Shares") or (ii) by purchase of outstanding Common Shares on the open market ("open-market purchases") on the New York Stock Exchange (the "NYSE"), the primary national securities exchange on which the common shares are traded (the "Exchange"), or elsewhere. If, on the payment date for any dividend or distribution the net asset value per Common Share is equal to or less than the market price per Common Share plus estimated brokerage trading fees (such condition being referred to herein as "market premium"), the Plan Agent will invest the dividend amount in newly issued Common Shares on behalf of the participants. The number of newly issued Common Shares to be credited to each participant's account will be determined by dividing the dollar amount of the dividend or distribution by the net asset value per Common Share on the date the Common Shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance may not exceed 5%. If, on the payment date for any dividend or distribution, the net asset value per Common Share is greater than the market value or market premium (such condition being referred to herein as "market discount"), the Plan Agent will invest the dividend amount in Common Shares acquired on behalf of the participants in open-market purchases.

In the event of a market discount on the payment date for any dividend or distribution, the Plan Agent will have until the last business day before the next date on which the Common Shares trade on an "ex-dividend" basis or in no event more than 30 days after the record date for such dividend, whichever is sooner (the "last purchase date"), to invest the dividend amount in Common Shares acquired in open-market purchases. It is contemplated that the Trust will pay monthly income dividends. Therefore, the period during which open-market purchases can be made will exist only from the record date of each dividend through the date before the next "ex-dividend" date which typically will be approximately ten days. If, before the Plan Agent has completed its open- market purchases, the market price of a Common Share exceeds the net asset value per Common Share, the average per Common Share purchase price paid by the Plan Agent may exceed the net asset value of the Common Shares, resulting in the acquisition of fewer Common Shares than if the dividend had been paid in newly issued Common Shares on the dividend record date. Because of the foregoing difficulty with respect to open market purchases, if the Plan Agent is unable to invest the full dividend amount in open market purchases during the purchase period or if the market discount shifts to a market premium during the purchase period, the Plan Agent may cease making open-market purchases and may invest the uninvested portion of the dividend amount in newly issued Common Shares at the net asset value per Common Share at the close of business on the last purchase date.

The Plan Agent maintains all Shareholders' accounts in the Plan and furnishes written confirmation of all transactions in the accounts, including information needed by Shareholders for tax records. Common Shares in the account of each Plan participant will be held by the Plan Agent in non-certificated form in the name of the Plan participant.

In the case of Shareholders such as banks, brokers or nominees that hold Common Shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of Common Shares certified from time to time by the record Shareholder and held for the account of beneficial owners who participate in the Plan.

There will be no brokerage charges with respect to Common Shares issued directly by the Trust as a result of dividends or capital gains distributions payable either in Common Shares or in cash. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open- market purchases in connection with the reinvestment of dividends.

MANAGEMENT CONTRACT

THIS AGREEMENT dated as of this 1st day of April 2002 between Pioneer High Income Trust, a Delaware business trust (the "Trust"), and Pioneer Investment Management, Inc., a Delaware corporation (the "Manager").

WITNESSETH

WHEREAS, the Trust is registered as a closed-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), and has filed with the Securities and Exchange Commission (the "Commission") a registration statement for the purpose of registering its shares for public offering under the Securities Act of 1933, as amended (the "1933 Act").

WHEREAS, the parties hereto deem it mutually advantageous that the Manager should be engaged, subject to the supervision of the Trust's Board of Trustees and officers, to manage the Trust.

NOW, THEREFORE, in consideration of the mutual covenants and benefits set forth herein, the Trust and the Manager do hereby agree as follows:

1. The Manager will regularly provide the Trust with investment research, advice and supervision and will furnish continuously an investment program for the Trust, consistent with the investment objectives and policies of the Trust. The Manager will determine from time to time what securities shall be purchased for the Trust, what securities shall be held or sold by the Trust and what portion of the Trust's assets shall be held uninvested as cash, subject always to the provisions of the Trust's Certificate of Trust, Agreement and Declaration of Trust, By-Laws and its registration statements under the 1940 Act and under the 1933 Act covering the Trust's shares, as filed with the Commission, and to the investment objectives, policies and restrictions of the Trust, as each of the same shall be from time to time in effect, and subject, further, to such policies and instructions as the Board of Trustees of the Trust may from time to time establish. To carry out such determinations, the Manager will exercise full discretion and act for the Trust in the same manner and with the same force and effect as the Trust itself might or could do with respect to purchases, sales or other transactions, as well as with respect to all other things necessary or incidental to the furtherance or conduct of such purchases, sales or other transactions.

2. The Manager will, to the extent reasonably required in the conduct of the business of the Trust and upon the Trust's request, furnish to the Trust research, statistical and advisory reports upon the industries, businesses, corporations or securities as to which such requests shall be made, whether or not the Trust shall at the time have any investment in such industries, businesses, corporations or securities. The Manager will use its best efforts in the preparation of such reports and will endeavor to consult the persons and sources believed by it to have information available with respect to such industries, businesses, corporations or securities.

3. The Manager will maintain all books and records with respect to the Trust's securities transactions required by subparagraphs (b)(5), (6), (9) and (10) and paragraph (f) of Rule 31a-1 under the 1940 Act (other than those records being maintained by the custodian or transfer agent appointed by the Trust) and preserve such records for the periods prescribed therefor by Rule 31a-2 under the 1940 Act. The Manager will also provide to the Board of Trustees such periodic and special reports as the Board may reasonably request.

4. Except as otherwise provided herein, the Manager, at its own expense, shall furnish to the Trust office space in the offices of the Manager, or in such other place as may be agreed upon from time to time, and all necessary office facilities, equipment and personnel for managing the Trust's affairs and investments, and shall arrange, if desired by the Trust, for members of the Manager's organization to serve as officers or agents of the Trust.

5. The Manager shall pay directly or reimburse the Trust for: (i) the compensation (if any) of the Trustees who are affiliated with, or "interested persons" (as defined in the 1940 Act) of, the Manager and all officers of the Trust as such; and (ii) all expenses not hereinafter specifically assumed by the Trust where such expenses are incurred by the Manager or by the Trust in connection with the management of the affairs of, and the investment and reinvestment of the assets of, the Trust.

6. The Trust shall assume and shall pay: (i) charges and expenses for fund accounting, pricing and appraisal services and related overhead, including, to the extent such services are performed by personnel of the Manager or its affiliates, office space and facilities, and personnel compensation, training and benefits; (ii) the charges and expenses of auditors; (iii) the charges and expenses of any custodian, transfer agent, administrator, plan agent, dividend disbursing agent and registrar appointed by the Trust; (iv) issue and transfer taxes chargeable to the Trust in connection with securities transactions to which the Trust is a party; (v) insurance premiums, interest charges, dues and fees for membership in trade associations and all taxes and corporate fees payable by the Trust to federal, state or other governmental agencies; (vi) fees and expenses involved in registering and maintaining registrations of the Trust and/or its shares with federal regulatory agencies, state or blue sky securities agencies and foreign jurisdictions, including the preparation of prospectuses and statements of additional information for filing with such regulatory authorities; (vii) all expenses of shareholders' and Trustees' meetings and of preparing, printing and distributing prospectuses, notices, proxy statements and all reports to shareholders and to governmental agencies; (viii) charges and expenses of legal counsel to the Trust and the Trustees; (ix) compensation of those Trustees of the Trust who are not affiliated with, or "interested persons" of, the Manager or the Trust (other than as Trustees); (x) the cost of preparing and printing share certificates; (xi) interest on borrowed money, if any; and
(xii) the fees and other expenses of listing the fund's shares on the New York Stock Exchange or any other national stock exchange.

7. In addition to the expenses described in Section 6 above, the Trust shall pay all brokers' and underwriting commissions chargeable to the Trust in connection with securities transactions to which the Trust is a party.

8. The Trust shall pay to the Manager, as compensation for the Manager's services and expenses assumed hereunder, a fee at the annual rate equal to 0.60% of the Trust's average weekly managed assets. "Managed assets" means the total assets of the Trust (including any assets attributable to any leverage that may be outstanding) minus the sum of accrued liabilities (other than debt representing financial leverage).

9. The management fee payable hereunder shall be computed daily and paid monthly in arrears. In the event of termination of this Agreement, the fee provided in
Section 8 shall be computed on the basis of the period ending on the last business day on which this Agreement is in effect subject to a pro rata adjustment based on the number of days elapsed in the current month as a percentage of the total number of days in such month.

10. The Manager may from time to time agree not to impose all or a portion of its fee otherwise payable hereunder (in advance of the time such fee or a portion thereof would otherwise accrue) and/or undertake to pay or reimburse the Trust for all or a portion of its expenses not otherwise required to be borne or reimbursed by the Manager. Any such fee reduction or undertaking may be discontinued or modified by the Manager at any time.

11. It is understood that the Manager may employ one or more sub-investment advisers (each a "Subadviser") to provide investment advisory services to the Trust by entering into a written agreement with each such Subadviser; provided, that any such agreement first shall be approved by the vote of a majority of the Trustees, including a majority of the Trustees who are not "interested persons" (as defined in the 1940 Act) of the Trust, the Manager or any such Subadviser, and otherwise approved in accordance with the requirements of the 1940 Act or an exemption therefrom. The authority given to the Manager in Sections 1 through 13 hereof may be delegated by it under any such agreement; provided, that any Subadviser shall be subject to the same restrictions and limitations on investments and brokerage discretion as the Manager. The Trust agrees that the Manager shall not be accountable to the Trust or the Trust's shareholders for any loss or other liability relating to specific investments directed by any Subadviser, even though the Manager retains the right to reverse any such investment because, in the event a Subadviser is retained, the Trust and the Manager will rely almost exclusively on the expertise of such Subadviser for the selection and monitoring of specific investments.

12. The Manager will not be liable for any error of judgment or mistake of law or for any loss sustained by reason of the adoption of any investment policy or the purchase, sale, or retention of any security on the recommendation of the Manager, whether or not such recommendation shall have been based upon its own investigation and research or upon investigation and research made by any other individual, firm or corporation, but nothing contained herein will be construed to protect the Manager against any liability to the Trust or its shareholders by reason of willful misfeasance, bad faith or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

13. Nothing in this Agreement will in any way limit or restrict the Manager or any of its officers, directors, or employees from buying, selling or trading in any securities for its or their own accounts or other accounts. The Manager may act as an investment adviser to any other person, firm or corporation, and may perform management and any other services for any other person, association, corporation, firm or other entity pursuant to any contract or otherwise, and take any action or do any thing in connection therewith or related thereto; and no such performance of management or other services or taking of any such action or doing of any such thing shall be in any manner restricted or otherwise affected by any aspect of any relationship of the Manager to or with the Trust or deemed to violate or give rise to any duty or obligation of the Manager to the Trust except as otherwise imposed by law. The Trust recognizes that the Manager, in effecting transactions for its various accounts, may not always be able to take or liquidate investment positions in the same security at the same time and at the same price.

14. In connection with purchases or sales of securities for the account of the Trust, neither the Manager nor any of its directors, officers or employees will act as a principal or agent or receive any commission except as permitted by the 1940 Act. The Manager shall arrange for the placing of all orders for the purchase and sale of securities for the Trust's account with brokers or dealers selected by the Manager. In the selection of such brokers or dealers and the placing of such orders, the Manager is directed at all times to seek for the Trust the most favorable execution and net price available except as described herein. It is also understood that it is desirable for the Trust that the Manager have access to supplemental investment and market research and security and economic analyses provided by brokers who may execute brokerage transactions at a higher cost to the Trust than may result when allocating brokerage to other brokers on the basis of seeking the most favorable price and efficient execution. Therefore, the Manager is authorized to place orders for the purchase and sale of securities for the Trust with such brokers, subject to review by the Trust's Trustees from time to time with respect to the extent and continuation of this practice. It is understood that the services provided by such brokers may be useful to the Manager in connection with its or its affiliates' services to other clients. In addition, subject to the Manager's obligation to seek the most favorable execution and net price available, the Manager may consider the sale of the Trust's shares in selecting brokers and dealers.

15. On occasions when the Manager deems the purchase or sale of a security to be in the best interest of the Trust as well as other clients, the Manager may, to the extent permitted by applicable laws and regulations, aggregate the securities to be sold or purchased in order to obtain the best execution and lower brokerage commissions, if any. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Manager in the manner it considers to be the most equitable and consistent with its fiduciary obligations to the Trust and to such clients.

16. This Agreement shall become effective on the date hereof and shall remain in force until December 31, 2003 and from year to year thereafter, but only so long as its continuance is approved in accordance with the requirements of the 1940 Act or an exemption therefrom, subject to the right of the Trust and the Manager to terminate this contract as provided in Section 17 hereof.

17. Either party hereto may, without penalty, terminate this Agreement by vote of its Board of Trustees or Directors, as the case may be, or by vote of a "majority of the outstanding voting securities" (as defined in the 1940 Act) of the Trust or the Manager, as the case may be, and the giving of 60 days' written notice to the other party.

18. This Agreement shall automatically terminate in the event of its assignment. For purposes of this Agreement, the term "assignment" shall have the meaning given it by Section 2(a)(4) of the 1940 Act.

19. The Trust agrees that in the event that neither the Manager nor any of its affiliates acts as an investment adviser to the Trust, the name of the Trust will be changed to one that does not contain the name "Pioneer" or otherwise suggest an affiliation with the Manager.

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

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

22. This Agreement and all performance hereunder shall be governed by and construed in accordance with the laws of The Commonwealth of Massachusetts.

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

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

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

Ladies and Gentlemen:

Pioneer High Income Trust, a Delaware business trust (the "Trust"), and the Trust's investment adviser, Pioneer Investment Management, Inc., a Delaware corporation and a Member of the UniCredito Italiano Banking Group, Register of Banking Groups("Pioneer") ( the "Adviser"), confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and each of the other Underwriters named in Schedule A hereto (collectively, the "Underwriters", which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch, UBS Warburg LLC and RBC Dain Rauscher Inc. are acting as representatives (in such capacity, the "Representatives"), with respect to the issue and sale by the Trust and the purchase by the Underwriters, acting severally and not jointly, of the respective number of common shares of beneficial interest, no par value per share, of the Trust ("Common Shares") set forth in said SCHEDULE A, and with respect to the grant by the Trust to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of [ ] additional Common Shares to cover over-allotments, if any. The aforesaid [ ] Common Shares (the "Initial Securities") to be purchased by the Underwriters and all or any part of the [ ] Common Shares subject to the option described in Section 2(b) hereof (the "Option Securities") are hereinafter called, collectively, the "Securities."

The Trust understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Trust has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form N-2 (No. 333-75458 and No. 811-10603) covering the registration of the Securities under the Securities Act of 1933, as amended (the "1933 Act"), including the related preliminary prospectus or prospectuses, and a notification on Form N-8A of registration of the Trust as an investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), and the rules and regulations of the Commission under the 1933 Act and the 1940 Act (the "Rules and Regulations"). Promptly after execution and delivery of this Agreement, the Trust will either (i) prepare and file a prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the Rules and Regulations and paragraph (c) or (h) of Rule 497 ("Rule 497") of the Rules and Regulations or (ii) if the Trust has elected to rely upon Rule
434 ("Rule 434") of the Rules and Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule 497. The information included in any such prospectus or in any such Term Sheet, as the case may be, that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective, if applicable, (a) pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph
(d) of Rule 434 is referred to as "Rule 434 Information." Each prospectus used before such registration statement became effective, and any prospectus that omitted, as applicable, the Rule 430A Information or the Rule 434 Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, including in each case any statement of additional information incorporated therein by reference, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto and schedules thereto at the time it became effective and including the Rule 430A Information and the Rule 434 Information, as applicable, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the Rules and Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final prospectus in the form first furnished to the Underwriters for use in connection with the offering of the Securities, including the statement of additional information incorporated therein by reference, is herein called the "Prospectus." If Rule 434 is relied on, the term "Prospectus" shall refer to the preliminary prospectus dated March 28, 2002 together with the Term Sheet and all references in this Agreement to the date of the Prospectus shall mean the date of the Term Sheet. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be.

SECTION 2. Sale and Delivery to Underwriters; Closing.

(a) INITIAL SECURITIES. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Trust agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Trust, at the price per share set forth in SCHEDULE B, the number of Initial Securities set forth in SCHEDULE A opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

(b) OPTION SECURITIES. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Trust hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional [ ] Common Shares in the aggregate at the price per share set forth in SCHEDULE B, less an amount per share equal to any dividends or distributions declared by the Trust and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 45 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Representatives to the Trust setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a "Date of Delivery") shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in SCHEDULE A opposite the name of such Underwriter bears to the total number of Initial Securities, subject in each case to such adjustments as Merrill Lynch in its discretion shall make to eliminate any sales or purchases of a fractional number of Option Securities.

(c) PAYMENT. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Clifford Chance Rogers & Wells LLP, 200 Park Avenue, New York, New York 10166, or at such other place as shall be agreed upon by the Representatives and the Trust, at 10:00
A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Trust (such time and date of payment and delivery being herein called "Closing Time").

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Trust, on each Date of Delivery as specified in the notice from the Representatives to the Trust.

Payment shall be made to the Trust by wire transfer of immediately available funds to a bank account designated by the Trust, against delivery to the Representatives for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d) DENOMINATIONS; REGISTRATION. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations and registered in such names as the Representatives may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be.

The Representatives will be entitled to an additional commission equal to 0.10% per year of the Trust's average quarterly total managed assets multiplied by the percentage of the entire offering of the common shares such Representative sells in the offering of the Securities. Each of the other Underwriters will also be entitled to this additional commission if such Underwriter sells Securities with an aggregate offering price of more than $50,000,000 in this offering. This additional commission will be payable quarterly during the continuance of the Management Agreement or other advisory agreement between the Trust and the Adviser.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to
Section 6(e) below) any such settlement is effected with the written consent of the Trust; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Trust or the Adviser by any Underwriter through Merrill Lynch expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) and provided further that the Trust will not be liable to any Underwriter with respect to any indemnification contained in this paragraph (a) to the extent that the Trust shall sustain the burden of proving that any such loss, liability, claim, damage or expense resulted from the fact that such Underwriter, in contravention of a requirement of this Agreement or applicable law, sold Securities to a person to whom such Underwriter failed to send or give, at or prior to the Closing Time or the Date of Delivery, as the case may be, a copy of the Prospectus, as then amended or supplemented if: (i) the Trust has previously furnished copies thereof (sufficiently in advance of the Closing Time or the Date of Delivery, as the case may be, to allow for distribution by the Closing Time or the Date of Delivery, as the case may be) to the Underwriter and the loss, liability, claim, damage or expense of such Underwriter resulted from an untrue statement or omission of a material fact contained in or omitted from the preliminary prospectus which was corrected in the Prospectus as, if applicable, amended or supplemented prior to the Closing Time or the Date of Delivery, as the case may be, and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person and
(ii) the failure to give or send such Prospectus by the Closing Time or the Date of Delivery, as the case may be, to such person would have constituted the sole basis for the claim asserted by such person against the party or parties asserting such loss, liability, claim, damage or expense as to which indemnification is sought pursuant to this paragraph (a).

(b) INDEMNIFICATION OF TRUST, ADVISER, TRUSTEES, DIRECTORS AND OFFICERS. Each Underwriter severally agrees to indemnify and hold harmless the Trust and the Adviser, their respective trustees and directors, each of the Trust's officers who signed the Registration Statement, and each person, if any, who controls the Trust or the Adviser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Trust or the Adviser by such Underwriter through Merrill Lynch expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(c) INDEMNIFICATION FOR MARKETING MATERIALS. In addition to the foregoing indemnification, the Trust and the Adviser also, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 6(a), as limited by the proviso set forth therein, with respect to any sales material.

(d) ACTIONS AGAINST PARTIES; NOTIFICATION. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement of such action, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, to assume the defense thereof with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense thereof, the indemnifying party shall not be liable to the indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such action where the indemnifying party does not assume the defense thereof, counsel to the indemnified parties shall be selected by Merrill Lynch in the case of parties indemnified pursuant to Section 6(a) above, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Trust and the Adviser, and in both cases, an indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(e) SETTLEMENT WITHOUT CONSENT IF FAILURE TO REIMBURSE. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution.

If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Trust and the Adviser on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Trust and the Adviser on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Trust and the Adviser on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Trust and the total underwriting discount received by the Underwriters (whether from the Trust or otherwise), in each case as set forth on the cover of the Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Trust and the Adviser on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Trust or the Adviser or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Trust, the Adviser and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each trustee of the Trust and each director of the Adviser, respectively, each officer of the Trust who signed the Registration Statement, and each person, if any, who controls the Trust or the Adviser, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Trust and the Adviser, respectively. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in SCHEDULE A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Trust or the Adviser submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Trust or the Adviser, and shall survive delivery of the Securities to the Underwriters.

SECTION 9. Termination of Agreement.

(a) TERMINATION; GENERAL. The Representatives may terminate this Agreement, by notice to the Trust, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Trust or the Adviser, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the Common Shares of the Trust has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the American Stock Exchange or the NYSE or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either Federal or New York authorities.

(b) LIABILITIES. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8 and 13 shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters.

If one or more of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase and of the Trust to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Trust to sell the relevant Option Securities, as the case may be, either the Representatives or the Trust shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "Underwriter" includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives, Merrill Lynch & Co., North Tower, World Financial Center, New York, New York 10080, attention of Equity Capital Markets; and notices to the Trust or the Adviser shall be directed, as appropriate, to the office of Pioneer Investment Management, Inc. at 60 State Street, Boston, Massachusetts 02109, Attention: General Counsel.

SECTION 12. Parties.

This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Trust, the Adviser and their respective partners and successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Trust, the Adviser and their respective successors and the controlling persons and officers, trustees and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Trust, the Adviser and their respective partners and successors, and said controlling persons and officers, trustees and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 13. GOVERNING LAW AND TIME.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SAID STATE. UNLESS OTHERWISE EXPLICITLY PROVIDED, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 14. Effect of Headings.

CUSTODIAN AGREEMENT

THIS AGREEMENT, dated as of July 1, 2001 between each of the open-end management investment companies listed on Appendix A hereto each a Fund (as amended from time to time) severally and not jointly, (each a FUND), and BROWN BROTHERS HARRIMAN & CO., a limited partnership formed under the laws of the State of New York (BBH&CO. or the CUSTODIAN). Each Fund is organized under either the laws of the State of Delaware or the Commonwealth of Massachusetts and registered with the Commission under the 1940 Act, as amended.

W I T N E S S E T H:

WHEREAS, the Fund wishes to employ BBH&Co. to act as custodian for the Fund and to provide related services, all as provided herein, and BBH&Co. is willing to accept such employment, subject to the terms and conditions herein set forth;

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, the Fund and BBH&Co. hereby agree, as follows:

1. APPOINTMENT OF CUSTODIAN. The Fund hereby appoints and employs BBH&Co. as the Fund's custodian for the term and subject to the conditions of this Agreement, including the related 17f-5 Delegation Schedule, and BBH&Co. hereby accepts such appointment. All Investments of the Fund delivered to the Custodian or its agents or Subcustodians shall be dealt with as provided in this Agreement. The duties of the Custodian with respect to the Fund's Investments shall be only as set forth expressly in this Agreement which duties are generally comprised of safekeeping and various administrative duties that will be performed in accordance with Instructions and as reasonably required to effect Instructions.

2. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE FUND. The Fund hereby represents, warrants and covenants each of the following:

1

2.1 This Agreement has been, and at the time of delivery of each Instruction such Instruction will have been, duly authorized, executed and delivered by the Fund. This Agreement does not conflict with or constitute a default under the Fund's prospectus, Certificate of Trust and By-Laws, or any other agreement, judgment, order or decree to which the Fund is a party or by which it is bound.

2.2 The Fund shall safeguard and shall be responsible for the safekeeping of any testkeys, identification codes, passwords, other security devices or statements of account with which the Custodian provides it. In furtherance and not in limitation of the foregoing, in the event the Fund utilizes any on-line service offered by the Custodian, the Fund shall be fully responsible for the security of its connecting terminal, access thereto and the proper and authorized use thereof and the initiation and application of continuing effective safeguards in respect thereof. Additionally, unless otherwise agreed in connection with the provision of such (service) (software) if the Fund uses any on-line or similar communications service made available by the Custodian, the Fund shall be responsible for ensuring the security of its access to the service and for its use of the service, and shall only attempt to access the service and the Custodian's computer systems as directed by the Custodian. Unless otherwise agreed in connection with the provision of such (service) (software). If the Custodian provides any computer software to the Fund relating to the services described in this Agreement, the Fund will only use the software for the purposes for which the Custodian provided the software to the Fund, and will abide by the license agreement accompanying the software and any other security policies which the Custodian provides to the Fund.

3. REPRESENTATION AND WARRANTY OF BBH&CO. BBH&Co. hereby represents and warrants that this Agreement has been duly authorized, executed and delivered by BBH&Co. and does not and will not violate any Applicable Law or conflict with or constitute a default under BBH&Co.'s limited partnership agreement or any agreement, instrument, judgment, order or decree to which BBH&Co. is a party or by which it is bound.

4. INSTRUCTIONS. Unless otherwise explicitly indicated herein, the Custodian shall perform its duties pursuant to Instructions. As used herein, the term INSTRUCTION shall mean a directive initiated by the Fund, acting directly or through its board of trustees, officers or other Authorized Persons, which directive shall conform to the requirements of this Section 4.

4.1 AUTHORIZED PERSONS. For purposes hereof, an AUTHORIZED PERSON shall be a person or entity authorized to give Instructions for or on behalf of the Fund by written notices to the Custodian or otherwise in accordance with procedures delivered to and acknowledged by the Custodian. Such Authorized Persons may be identified by the Board of Trustees of the Fund by name, title or positions, may include officers of the Fund authorized by the Board of Trustees to name additional Authorized Persons and may include officers or employees of the Fund's investment adviser or its affiliates. The Custodian may treat any Authorized Person as having full authority of the Fund to issue Instructions hereunder unless the notice of authorization contains explicit limitations as to said authority. The Custodian may not

2

treat any Instruction from an Authorized Person directing the delivery of securities or payment to such Authorized Person to be valid for purposes of this Agreement. The Custodian shall be entitled to rely upon the authority of Authorized Persons until it receives appropriate written notice from the Fund to the contrary.

4.2 FORM OF INSTRUCTION. Each Instruction shall be transmitted by such secured or authenticated electro-mechanical means as the Custodian shall make available to the Fund from time to time unless the Fund shall elect to transmit such Instruction in accordance with Subsections 4.2.1 through 4.2.3 of this Section.
4.2.1 FUND DESIGNATED SECURED-TRANSMISSION METHOD. Instructions may be transmitted through a secured or tested electro-mechanical means identified by the Fund or by an Authorized Person entitled to give Instruction and acknowledged and accepted by the Custodian; it being understood that such acknowledgment shall authorize the Custodian to receive and process such means of delivery but shall not represent a judgment by the Custodian as to the reasonableness or security of the method determined by the Authorized Person.

4.2.2 WRITTEN INSTRUCTIONS. Instructions may be transmitted in a writing that bears the manual signature or initials of Authorized Persons.

4.2.3 OTHER FORMS OF INSTRUCTION. Instructions may also be transmitted by another means determined by the Fund or Authorized Persons and acknowledged and accepted by the Custodian (subject to the same limits as to acknowledgements as is contained in Subsection 4.2.1, above) including Instructions given orally or by SWIFT, telex or telefax (whether tested or untested).

When an Instruction is given by means established under Subsections 4.2.1 through 4.2.3, it shall be the responsibility of the Custodian to use reasonable care to adhere to any security or other procedures established in writing between the Custodian and the Authorized Person (and such other procedures as are customarily adhered to by custodians to protect client assets) with respect to such means of Instruction, but such Authorized Person shall be solely responsible for determining that the particular means chosen is reasonable under the circumstances. Telephonic or oral instructions shall be considered proper Instructions if the Custodian reasonably believes them to have been given by an Authorized Person. Telephonic or oral instructions shall be confirmed by methods established in accordance with Section 4.2.1. With respect to telefax instructions, the parties agree and acknowledge that receipt of legible instructions cannot be assured, that the Custodian cannot verify that authorized signatures on telefax instructions are original or properly affixed, and that the Custodian shall not be liable for losses or expenses incurred through actions taken in reliance on inaccurately stated, illegible or unauthorized telefax instructions; provided that if the Custodian receives Instructions that it determines to be illegible, the Custodian shall promptly seek confirmation of such Instructions from the Authorized Person sending such Instruction. The provisions of Section 4A of the Uniform Commercial Code shall apply to Funds Transfers performed in accordance with Instructions. The Funds Transfer Services Schedule to this Agreement shall comprise a designation of form of a means of delivering Instructions selected by the Custodian for purposes of this Section 4.2.

3

4.3 COMPLETENESS AND CONTENTS OF INSTRUCTIONS. The Authorized Person shall be responsible for assuring the adequacy and accuracy of Instructions. Particularly, upon any acquisition or disposition or other dealing in the Fund's Investments and upon any delivery and transfer of any Investment or monies, the person initiating such Instruction shall give the Custodian an Instruction with appropriate detail, including, without limitation:

         4.3.1  The transaction date and the date and location of
settlement;

         4.3.2  The specification of the type of transaction;

4.3.3 A description of the Investments or monies in question, including, as appropriate, quantity, price per unit, amount of money to be received or delivered and currency information; and

4.3.4 The name of the broker or similar entity concerned with execution of the transaction.

If the Custodian shall determine that an Instruction is either unclear or incomplete, the Custodian shall give prompt notice of such determination to the Fund, and the Fund shall thereupon amend or otherwise reform such Instruction.

4.4 TIMELINESS OF INSTRUCTIONS. In giving an Instruction, the Fund shall take into consideration delays which may occur due to the involvement of a Subcustodian or agent, differences in time zones, and other factors particular to a given market, exchange or issuer. When the Custodian has established specific timing requirements or deadlines with respect to particular classes of Instructions and adequate notice thereof has been provided to the Fund, or when an Instruction is received by the Custodian at such a time that it could not reasonably be expected to have acted on such Instruction due to time zone differences or other factors beyond its reasonable control, the Custodian shall not be responsible for any increased risk or failure to timely complete any settlement to the extent that such risk arises out of such delay.

5. SAFEKEEPING OF FUND ASSETS. The Custodian shall hold Investments delivered to it or Subcustodians for the Fund in accordance with the provisions of this Section. The Custodian shall not be responsible for the safekeeping of Investments not delivered or that are not caused to be issued to it or its Subcustodians or pre-existing faults or defects in Investments that are delivered to the Custodian, or its Subcustodians. The Custodian is hereby authorized to hold with itself or a Subcustodian, and to record in one or more accounts, all Investments delivered to and accepted by the Custodian, any Subcustodian or their respective agents pursuant to an Instruction or in consequence of any corporate

4

action. The Custodian shall hold Investments for the account of the Fund and shall segregate Investments from assets belonging to the Custodian and shall cause its Subcustodians to segregate Investments from assets belonging to the Subcustodian in an account held for the Fund or in an account maintained by the Subcustodian generally for non-proprietary assets of the Custodian.

5.1 USE OF SECURITIES DEPOSITORIES. The Custodian may deposit and maintain Investments in any Securities Depository, either directly or through one or more Subcustodians appointed by the Custodian. Investments held in a Securities Depository shall be held (a) subject to the agreement, rules, statement of terms and conditions or other document or conditions effective between the Securities Depository and the Custodian or the Subcustodian, as the case may be, and (b) in an account for the Fund or in bulk segregation in an account maintained for the non-proprietary assets of the entity holding such Investments in the Securities Depository. If the rules and regulations of the Securities Depository prevent the Custodian, the Subcustodian or (any agent of either) from holding its clients' assets in such a separate account, the Custodian, the Subcustodian or other agent shall as appropriate segregate such Investments for benefit of the Fund or for benefit of clients of the Custodian generally on its own books.

5.2 CERTIFICATED ASSETS. Investments which are certificated may be held in registered or bearer form: (a) in the Custodian's vault; (b) in the vault of a Subcustodian or agent of the Custodian or a Subcustodian; or (c) in an account maintained by the Custodian, Subcustodian or agent at a Securities Depository; all in accordance with customary market practice in the jurisdiction in which any Investments are held provided that Securities are held in the name of the Fund or in an account of the Custodian containing only the assets of the Fund or only assets held as fiduciary or custodian for customers..

5.3 REGISTERED ASSETS. Investments which are registered may be registered in the name of the Custodian, a Subcustodian, or in the name of the Fund or a nominee for any of the foregoing, and may be held in any manner set forth in paragraph 5.2 above with or without any identification of fiduciary capacity in such registration.

5.4 BOOK ENTRY ASSETS. Investments which are represented by book-entry may be so held in an account maintained by the Book-entry Agent on behalf of the Custodian, a Subcustodian or another agent of the Custodian, or a Securities Depository.

5.5 REPLACEMENT OF LOST INVESTMENTS. In the event of a loss of Investments for which the Custodian is responsible under the terms of this Agreement, the Custodian shall replace such Investment, or in the event that such replacement cannot be effected, the Custodian shall pay to the Fund the fair market value of such Investment based on

5

the last available price as of the close of business in the relevant market on the date that a claim was first made to the Custodian with respect to such loss, or, if less, such other amount as shall be agreed by the parties as the date for settlement.

6. ADMINISTRATIVE DUTIES OF THE CUSTODIAN. The Custodian shall perform the following administrative duties with respect to Investments of the Fund.

6.1 PURCHASE OF INVESTMENTS. Pursuant to Instruction, Investments purchased for the account of the Fund shall be paid for (a) against delivery thereof to the Custodian or a Subcustodian, as the case may be, either directly or through a Clearing Corporation or a Securities Depository (in accordance with the rules of such Securities Depository or such Clearing Corporation), or (b) otherwise in accordance with an Instruction or Applicable Law. However, (i) in the case of repurchase agreements entered into by the Fund, the Custodian may release funds to a securities system or to a Subcustodian prior to the receipt of advice from the securities system or Subcustodian that the securities underlying such repurchase agreement have been transferred by book entry into the Account of the Custodian maintained with such securities system or Subcustodian, so long as such payment instructions to the securities system or Subcustodian include a requirement that delivery is only against payment for securities, (ii) in the case of foreign exchange contracts, options, time deposits, call account deposits, currency deposits, and other deposits, contracts or options, the Custodian may make payment therefor without receiving an instrument evidencing said deposit, contract or option so long as such payment instructions detail specific securities to be acquired, and (iii) in the case of securities for which payment for the security and receipt of the instrument evidencing the security are under generally accepted trade practice or the terms of the instrument representing the security expected to take place in different locations or through separate parties, the Custodian may make payment for such securities prior to delivery thereof in accordance with such generally accepted trade practice or the terms of the instrument representing such security.

6.2 SALE OF INVESTMENTS. Pursuant to Instruction, Investments sold for the account of the Fund shall be delivered (a) against payment therefor in cash, by certified check, bank cashiers check, bank credit or by bank wire transfer,
(b) by credit to the account of the Custodian or the applicable Subcustodian, as the case may be, with a Clearing Corporation or a Securities Depository (in accordance with the rules of such Securities Depository or such Clearing Corporation), or (c) otherwise in accordance with an Instruction, Applicable Law or the terms of the instrument representing such Investment; provided, however, that (i) in the case of delivery of physical certificates or

6

instruments representing securities, the Custodian may make delivery to the broker buying the securities, against receipt therefor, for examination in accordance with "street delivery" custom, provided that the payment therefor is to be made to the Custodian (which payment may be made by a broker's check) or that such securities are to be returned to the Custodian, and (ii) in the case of securities referred to in the last sentence of Section 6.1, the Custodian may make settlement, including with respect to the form of payment, in accordance with generally accepted trade practice relating to such securities or the terms of the instrument representing said security.

6.3 DELIVERY AND RECEIPT IN CONNECTION WITH BORROWINGS OF THE FUND OR OTHER COLLATERAL AND MARGIN REQUIREMENTS. Pursuant to Instruction, the Custodian may deliver or receive Investments or cash of the Fund in connection with borrowings or loans by the Fund and other collateral and margin requirements.

6.4 FUTURES AND OPTIONS. If, pursuant to an Instruction, the Custodian shall become a party to an agreement with the Fund and a futures commission merchant regarding margin accounts (TRI-PARTY AGREEMENT), the Custodian shall
(a) receive and retain, to the extent the same are provided to the Custodian, confirmations or other documents evidencing the purchase or sale by the Fund of exchange-traded futures contracts and commodity options, (b) when required by such Tri-Party Agreement, deposit and maintain in an account opened pursuant to such Agreement (MARGIN ACCOUNT), segregated either physically or by book-entry in a Securities Depository for the benefit of any futures commission merchant, such Investments as the Fund shall have designated as initial, maintenance or variation "margin" deposits or other collateral intended to secure the Fund's performance of its obligations under the terms of any exchange-traded futures contracts and commodity options; and (c) thereafter pay, release or transfer Investments into or out of the margin account in accordance with the provisions of such Agreement. Alternatively, the Custodian may deliver Investments, in accordance with an Instruction, to a futures commission merchant for purposes of margin requirements in accordance with Rule 17f-6. The Custodian shall in no event be responsible for the acts and omissions of any futures commission merchant to whom Investments are delivered pursuant to this Section; for the sufficiency of Investments held in any Margin Account; or, for the performance of any terms of any exchange-traded futures contracts and commodity options.

6.5 CONTRACTUAL OBLIGATIONS AND SIMILAR INVESTMENTS. From time to time, the Fund's Investments may include Investments that are not ownership interests as may be represented by certificate (whether registered or bearer), by entry in a Securities Depository or by book entry agent, registrar or similar agent for recording ownership interests in the relevant Investment. If the Fund shall at any time acquire such Investments, including without limitation deposit obligations, loan participations, repurchase agreements and derivative arrangements, the Custodian shall (a) receive and

7

retain, to the extent the same are provided to the Custodian, confirmations or other documents evidencing the arrangement; and (b) perform on the Fund's account in accordance with the terms of the applicable arrangement, but only to the extent directed to do so by Instruction. The Custodian shall have no responsibility for agreements running to the Fund as to which it is not a party other than to retain, to the extent the same are provided to the Custodian, documents or copies of documents evidencing the arrangement and, in accordance with Instruction, to include such arrangements in reports made to the Fund.

6.6 EXCHANGE OF SECURITIES. Unless otherwise directed by Instruction, the Custodian shall: after prior notice of such action to the Fund: (a) exchange securities held for the account of the Fund for other securities in connection with any reorganization, recapitalization, conversion, split-up, change of par value of shares or similar event: and (b) deposit any such securities in accordance with the terms of any reorganization or protective plan.

Unless otherwise directed by Instruction, the Custodian may surrender securities after prior notice of such action to the Fund: (a) in temporary form for definitive securities; (b) for transfer into the name of an entity allowable under Section 5.3; and (c) for a different number of certificates or instruments representing the same number of shares or the same principal amount of indebtedness.

6.8 RIGHTS, WARRANTS, ETC. Pursuant to Instruction, the Custodian shall
(a) deliver warrants, puts, calls, rights or similar securities to the issuer or trustee thereof, or to any agent of such issuer or trustee, for purposes of exercising such rights or selling such securities, and (b) deposit securities in response to any invitation for the tender thereof.

6.9 MANDATORY CORPORATE ACTIONS. Unless otherwise directed by Instruction, the Custodian shall after prior notice of such action to the Fund: (a) comply with the terms of all mandatory or compulsory exchanges, calls, tenders, redemptions or similar rights of securities ownership affecting securities held on the Fund's account and promptly notify the Fund of such action; and (b) collect all stock dividends, rights and other items of like nature with respect to such securities.

6.10 INCOME COLLECTION. Unless otherwise directed by Instruction, the Custodian shall collect any amount due and payable to the Fund with respect to Investments and promptly credit the amount collected to a Principal or Agency Account; provided, however, that the Custodian shall not be responsible for:
(a) the collection of amounts due and payable with respect to Investments that are in default; or (b) the collection of cash or share entitlements with respect to Investments that are not registered in the name of the Custodian or its Subcustodians. The Custodian is hereby authorized to endorse and deliver any instrument required to be so endorsed and delivered to effect collection of any amount due and payable to the Fund with respect to Investments.

8

6.11 OWNERSHIP CERTIFICATES AND DISCLOSURE OF THE FUND'S INTEREST. The Custodian is hereby authorized to execute on behalf of the Fund ownership certificates, affidavits or other disclosure required under Applicable Law or established market practice in connection with the receipt of income, capital gains or other payments by the Fund with respect to Investments, or in connection with the sale, purchase or ownership of Investments.

With respect to securities issued in the United States of America, the Custodian [ ] may [ ] may not release the identity of the Fund to an issuer which requests such information pursuant to the Shareholder Communications Act of 1985 for the specific purpose of direct communications between such issuer and the Fund. IF NO BOX IS CHECKED, THE CUSTODIAN SHALL RELEASE SUCH INFORMATION UNTIL IT RECEIVES CONTRARY INSTRUCTIONS FROM THE FUND. With respect to securities issued outside of the United States of America, information shall be released in accordance with law or custom of the particular country in which such security is located.

6.12 PROXY MATERIALS. The Custodian shall deliver, or cause to be delivered, to the Fund proxy forms, notices of meeting, and any other notices or announcements affecting or relating to Investments received by the Custodian or any nominee. Unless authorized to do so by Instructions or proxy, neither the Custodian nor any Subcustodian shall vote any securities held for the Fund pursuant to this Agreement.

6.13. TAXES. The Custodian shall, where applicable, assist the Fund in the reclamation of taxes withheld on dividends and interest payments received by the Fund. In the performance of its duties with respect to tax withholding and reclamation, the Custodian shall be entitled to rely on the advice of counsel and upon information and advice regarding the Fund's tax status that is received from or on behalf of the Fund without duty of separate inquiry.

6.14. USE OF SEGREGATED ACCOUNTS. Upon receipt of Instructions, the Custodian shall establish and maintain on its books a segregated account or accounts on behalf of the Fund into which account or accounts may be transferred cash and/or securities of the Fund (i) in accordance with the provisions of any agreement among the Fund, the Custodian and a broker-dealer registered under the Securities Exchange Act of 1934 and a member of the National Association of Securities Dealers, Inc. (or any futures commission merchant registered under the Commodity Exchange Act) relating to compliance with the rules of the Options Clearing Corporation and of any registered national securities exchange (or the Commodity Futures Trading Commission or any registered contract market), or any similar organization or organizations, regarding escrow or other arrangements in connection with transactions by the Fund, (ii) for purposes of segregating cash or securities in connection with options purchased, sold or written by the Fund or commodity futures contracts or options thereon purchased or sold by the Fund,
(iii) for the purposes of compliance by the Fund with the procedures required by Investment Company Act and (iv) as mutually agreed from time to time between the Fund and the Custodian.

6.15 OTHER DEALINGS. The Custodian shall otherwise act as directed by Instruction, including without

9

limitation effecting the free payments of moneys or the free delivery of securities, provided that such Instruction shall indicate the purpose of such payment or delivery and that the Custodian shall record the party to whom such payment or delivery is made.

The Custodian shall attend to all nondiscretionary details in connection with the sale, exchange, substitution, transfer or purchase or other administration of Investments, except as otherwise directed by an Instruction.

In fulfilling the duties set forth in Sections 6.6 through 6.10 above, the Custodian shall promptly provide to the Fund all information pertaining to a corporate action which the Custodian actually receives; provided that the Custodian shall not be responsible for the completeness or accuracy of any information it receives. Any advance credit of cash or shares expected to be received as a result of any corporate action shall be subject to actual collection and may, when the Custodian deems collection unlikely, be reversed by the Custodian.

The Custodian may at any time or times in its discretion appoint (and may at any time remove) agents (other than Subcustodians) to carry out some or all of the administrative provisions of this Agreement (AGENTS), provided, however, that the appointment of such agent shall not relieve the Custodian of its administrative obligations under this Agreement.

7. CASH ACCOUNTS, DEPOSITS AND MONEY MOVEMENTS. Subject to the terms and conditions set forth in this Section 7, the Fund hereby authorizes the Custodian to open and maintain, with itself or with Subcustodians, cash accounts in United States Dollars, in such other currencies as are the currencies of the countries in which the Fund maintains Investments or in such other currencies as the Fund shall from time to time request by Instruction.

7.1 TYPES OF CASH ACCOUNTS. Cash accounts opened on the books of the Custodian (PRINCIPAL ACCOUNTS) shall be opened in the name of the Fund. Such accounts collectively shall be a deposit obligation of the Custodian and shall be subject to the terms of this Section 7 and the general liability provisions contained in Section 9. Cash accounts opened on the books of a Subcustodian may be opened in the name of the Fund or the Custodian or in the name of the Custodian for its customers generally (AGENCY ACCOUNTS). Such deposits shall be obligations of the Subcustodian and shall be treated as an Investment of the Fund. Accordingly, the responsibility of the Custodian with respect to cash accounts shall be the same as and no greater than other Investments. Accordingly, the Custodian shall not be liable for

10

their repayment in the event such Subcustodian, by reason of its bankruptcy, insolvency or otherwise, fails to make repayment.

7.2 PAYMENTS AND CREDITS WITH RESPECT TO THE CASH ACCOUNTS. The Custodian shall make payments from or deposits to any of said accounts in the course of carrying out its administrative duties, including but not limited to income collection with respect to the Fund's Investments, and otherwise in accordance with Instructions. The Custodian and its Subcustodians shall be required to credit amounts to the cash accounts only when moneys are actually received in cleared funds in accordance with banking practice in the country and currency of deposit. Any credit made to any Principal or Agency Account before actual receipt of cleared funds shall be provisional and may be reversed by the Custodian in the event such payment is not actually collected. Unless otherwise specifically agreed in writing by the Custodian or any Subcustodian, all deposits shall be payable only at the branch of the Custodian or Subcustodian where the deposit is made or carried.

7.3 CURRENCY AND RELATED RISKS. The Fund bears risks of holding or transacting in any currency. The Custodian shall not be liable for any loss or damage arising from the applicability of any law or regulation now or hereafter in effect, or from the occurrence of any event, which may delay or affect the transferability, convertibility or availability of any currency in the country
(a) in which such Principal or Agency Accounts are maintained or (b) in which such currency is issued, and in no event shall the Custodian be obligated to make payment of a deposit denominated in a currency during the period during which its transferability, convertibility or availability has been affected by any such law, regulation or event. Without limiting the generality of the foregoing, neither the Custodian nor any Subcustodian shall be required to repay any deposit made at a foreign branch of either the Custodian or Subcustodian if such branch cannot repay the deposit due to a cause for which the Custodian would not be responsible in accordance with the terms of Section 9 of this Agreement unless the Custodian or such Subcustodian expressly agrees in writing to repay the deposit under such circumstances. All currency transactions in any account opened pursuant to this Agreement are subject to exchange control regulations of the United States and of the country where such currency is the lawful currency or where the account is maintained. Any taxes, costs, charges or fees imposed on the convertibility of a currency held by the Fund shall be for the account of the Fund.

7.4 FOREIGN EXCHANGE TRANSACTIONS. The Custodian shall, subject to the terms of this Section, settle foreign exchange transactions (including contracts, futures, options and options on futures) on behalf and for the account of the Fund with such currency brokers or banking institutions, including Subcustodians, as the Fund may direct pursuant to Instructions. The Custodian may act as principal in any foreign exchange transaction with the Fund in accordance with

11

Section 7.4.2 of this Agreement. The obligations of the Custodian in respect of all foreign exchange transactions (whether or not the Custodian shall act as principal in such transaction) shall be contingent on the free, unencumbered transferability of the currency transacted on the actual settlement date of the transaction.

7.4.1 THIRD PARTY FOREIGN EXCHANGE TRANSACTIONS. The Custodian shall process foreign exchange transactions (including without limitation contracts, futures, options, and options on futures), where any third party acts as principal counterparty to the Fund on the same basis it performs duties as agent for the Fund with respect to any other of the Fund's Investments. Accordingly the Custodian shall only be responsible for delivering or receiving currency on behalf of the Fund in respect of such contracts pursuant to Instructions. The Custodian shall not be responsible for the failure of any counterparty (including any Subcustodian) in such agency transaction to perform its obligations thereunder. The Custodian (a) shall transmit cash and Instructions to and from the currency broker or banking institution with which a foreign exchange contract or option has been executed pursuant hereto, (b) may make free outgoing payments of cash in the form of U.S. Dollars or foreign currency without receiving confirmation of a foreign exchange contract or option or confirmation that the countervalue currency completing the foreign exchange contract has been delivered or received or that the option has been delivered or received, and (c) shall hold all confirmations, certificates and other documents and agreements received by the Custodian and evidencing or relating to such foreign exchange transactions in safekeeping. Subject to the Custodian's Standard of Care under this Agreement, the Fund accepts full responsibility for its use of third-party foreign exchange dealers and for execution of said foreign exchange contracts and options and understands that the Fund shall be responsible for any and all costs and interest charges which may be incurred by the Fund or the Custodian as a result of the failure or delay of third parties to deliver foreign exchange.

7.4.2 FOREIGN EXCHANGE WITH THE CUSTODIAN AS PRINCIPAL. The Custodian may undertake foreign exchange transactions with the Fund as principal as the Custodian and the Fund may agree from time to time. In such event, the foreign exchange transaction will be performed in accordance with the particular agreement of the parties, or in the event a principal foreign exchange transaction is initiated by Instruction in the absence of specific agreement, such transaction will be performed in accordance with the usual commercial terms of the Custodian.

7.5 DELAYS. If no event of Force Majeure shall have occurred and be continuing and in the event that a delay shall have been caused by the negligence or willful misconduct of the Custodian in carrying out an Instruction to credit or transfer cash, the Custodian, without limiting the Custodian's obligations under Section 9. shall be liable to the Fund: (a) with respect to Principal Accounts, for interest to be calculated at the rate customarily paid on such deposit and currency by the Custodian on overnight deposits at the time the delay occurs for the period from the day when the transfer should have been effected until the day it is in fact effected; and, (b) with respect to Agency Accounts, for interest to be calculated at the rate customarily paid on such deposit and currency by the Subcustodian on overnight deposits at the time the delay occurs for the period from the day when the transfer should have been effected until the day it is in fact effected. The Custodian shall not be liable for delays in carrying out such Instructions to transfer cash which are not due to the Custodian's own negligence or willful misconduct.

12

7.6 ADVANCES. If, for any reason in the conduct of its safekeeping duties pursuant to Section 5 hereof or its administration of the Fund's assets pursuant to Section 6 hereof, the Custodian or any Subcustodian advances monies to facilitate settlement or otherwise for the benefit of the Fund (whether or not any Principal or Agency Account shall be overdrawn either during, or at the end of, any Business Day), (collectively, an "Advance"), then in such event any Investment at any time held for the account of the Fund by the Custodian or a Subcustodian shall be security for such Advance and if the Fund shall fail to repay the Custodian promptly, the Custodian shall be entitled to utilize available cash and to dispose of the Fund's Investments to the extent necessary to obtain reimbursement.

Neither the Custodian nor any Subcustodian shall be obligated to advance monies to the Fund, and in the event that such Advance occurs, any transaction giving rise to an Advance shall be for the account and risk of the Fund and shall not be deemed to be a transaction undertaken by the Custodian for its own account and risk. If such Advance shall have been made by a Subcustodian or any other person, the Custodian may assign any rights granted or arising to the Custodian hereunder to such Subcustodian or other person. The Custodian may assign any rights it has hereunder to a Subcustodian or third party.

7.7 INTEGRATED ACCOUNT. For purposes hereof, deposits maintained in all Principal Accounts (whether or not denominated in Dollars) of each series of the Fund shall collectively constitute a single and indivisible current account with respect to the series' obligations to the Custodian, or its assignee, and balances in such Principal Accounts shall be available for satisfaction of the series' obligations under this Section 7.

8. SUBCUSTODIANS AND SECURITIES DEPOSITORIES. Subject to the provisions hereinafter set forth in this Section 8, the Fund hereby authorizes the Custodian to utilize Securities Depositories to act on behalf of the Fund and to appoint from time to time and to utilize Subcustodians. With respect to securities and funds held by a Subcustodian, either directly or indirectly (including by a Securities Depository or Clearing Corporation), notwithstanding any provisions of this Agreement to the contrary, payment for securities purchased and delivery of securities sold may be made prior to receipt of securities or payment, respectively, and securities or payment may be received in a form, in accordance with

13

(a) governmental regulations, (b) rules of Securities Depositories and clearing agencies, (c) generally accepted trade practice in the applicable local market, (d) the terms and characteristics of the particular Investment, or (e) the terms of Instructions.

8.1 DOMESTIC SUBCUSTODIANS AND SECURITIES DEPOSITORIES. The Custodian may deposit and/or maintain, either directly or through one or more agents appointed by the Custodian, Investments of the Fund in any Securities Depository in the United States, including The Depository Trust Company, provided such Depository meets applicable requirements of the Federal Reserve Bank or of the Securities and Exchange Commission. The Custodian may, at any time and from time to time, appoint any bank as defined in Section 2(a)(5) of the 1940 Act meeting the requirements of a custodian under Section 17(f) of the 1940 Act and the rules and regulations thereunder, to act on behalf of the Fund as a Subcustodian for purposes of holding Investments of the Fund in the United States.

8.2 FOREIGN SUBCUSTODIANS AND SECURITIES DEPOSITORIES. Unless instructed otherwise by the Fund, the Custodian may deposit and/or maintain non-U.S. Investments of the Fund in any non-U.S. Securities Depository provided such Securities Depository meets the requirements of an "eligible securities depository" under Rule 17f-7 promulgated under the 1940 Act, or any successor rule or regulation ("Rule 17f-7") or which by order of the Securities and Exchange Commission is exempted therefrom. Prior to the time that securities are placed with such depository, but subject to the provisions of Section 8.2.4 below, the Custodian shall have prepared an assessment of the custody risks associated with maintaining assets with the Securities Depository and shall have established a system to monitor such risks on a continuing basis in accordance with Subsection 8.2.3 of this Section and Rule 17f-7. Additionally, the Custodian may, at any time and from time to time, appoint (a) any bank, trust company or other entity meeting the requirements of an "eligible foreign custodian" under Rule 17f-5 or which by order of the Securities and Exchange Commission is exempted therefrom, or (b) any bank as defined in Section 2(a)(5) of the 1940 Act meeting the requirements of a custodian under Section 17(f) of the 1940 Act and the rules and regulations thereunder, to act on behalf of the Fund as a Subcustodian for purposes of holding Investments of the Fund outside the United States. Such appointment of foreign Subcustodians shall be subject to approval of the Fund or the Foreign Custody Manager in accordance with Subsections 8.2.1 and 8.2.2 hereof, and use of non-U.S. Securities Depositories shall be subject to the terms of Subsections 8.2.3 and 8.2.4 hereof. An Instruction to open an account in a given country shall comprise authorization of the Custodian to hold assets in such country in accordance with the terms of this Agreement. The Custodian shall not be required to make independent inquiry as to the authorization of the Fund to invest in such country.

14

8.2.1 BOARD APPROVAL OF FOREIGN SUBCUSTODIANS. Unless and except to the extent that the Board has delegated to and the Custodian has accepted delegation of review of certain matters concerning the appointment of Subcustodians pursuant to Subsection 8.2.2, the Custodian shall, prior to the appointment of any Subcustodian for purposes of holding Investments of the Fund outside the United States, obtain written confirmation of the approval of the Board of Trustees of the Fund with respect to (a) the identity of a Subcustodian, and (b) the Subcustodian agreement which shall govern such appointment, such approval to be signed by an Authorized Person.

8.2.2 DELEGATION OF BOARD REVIEW OF SUBCUSTODIANS. From time to time, the Custodian may agree to perform certain reviews of Subcustodians and of Subcustodian Contracts as delegate of the Fund's Board. In such event, the Custodian's duties and obligations with respect to this delegated review will be performed in accordance with the terms of the attached 17f-5 Delegation Schedule to this Agreement.

8.2.3 MONITORING AND RISK ASSESSMENT OF SECURITIES DEPOSITORIES. Prior to the placement of any assets of the Fund with a non-U.S. Securities Depository, the Custodian: (a) shall provide to the Fund or its authorized representative an assessment of the custody risks associated with maintaining assets within such Securities Depository; and (b) shall have established a system to monitor the custody risks associated with maintaining assets with such Securities Depository on a continuing basis and to promptly notify the Fund or its Investment Adviser of any material changes in such risk. In performing its duties under this subsection, the Custodian shall use reasonable care and may rely on such reasonable sources of information. It is acknowledged that information procured through some sources may not be independently verifiable by the Custodian and that direct access to Securities Depositories is limited under most circumstances. Accordingly, the Custodian shall not be responsible for errors or omissions in its duties hereunder provided that it has performed its monitoring and assessment duties with reasonable care, prudence and diligence. The risk assessment shall be provided to the Fund or its Investment Adviser by such means as the Custodian shall reasonably establish. Advices of material change in such assessment may be provided by the Custodian in the manner established as customary between the Fund and the Custodian for transmission of material market information.

8.3 RESPONSIBILITY FOR SUBCUSTODIANS. The Custodian shall be liable to the Fund for any loss or damage to the Fund caused by or resulting from the acts or omissions of any Subcustodian to the extent that under the terms set forth in the subcustodian agreement between the Custodian and the Subcustodian, the Subcustodian has failed to perform in accordance with the standard of conduct imposed under such subcustodian agreement as determined in accordance with the law which is adjudicated to govern such agreement and in accordance with any determination of any court as to the duties of said Subcustodian pursuant to said agreement. The Custodian shall also be liable to the Fund for its own negligence in connection with the delivery of any securities or funds held by it to any Subcustodian.

8.4 NEW COUNTRIES. The Fund shall be responsible for informing the Custodian sufficiently in advance of a

15

proposed investment which is to be held in a country in which no Subcustodian is authorized to act in order that the Custodian shall, if it deems appropriate to do so, have sufficient time to establish a subcustodial arrangement in accordance herewith. In the event, however, the Custodian is unable to establish such arrangements prior to the time such investment is to be acquired, the Custodian is authorized to designate at its discretion a local safekeeping agent, and the use of such local safekeeping agent shall be at the sole risk of the Fund, and accordingly the Custodian shall be responsible to the Fund for the actions of such agent if and only to the extent the Custodian shall have recovered from such agent for any damages caused the Fund by such agent. The Custodian shall provide the Fund prompt notice if it receives Instruction with respect to a security to be settled in a country for which a Subcustodian has not been appointed or if the Custodian has appointed such an agent and at the request of the Fund, the Custodian agrees to remove any security held on behalf of the Fund by such an agent to a Subcustodian. Under such circumstances, the Custodian shall collect income and respond to corporate developments on a best efforts basis.

9. RESPONSIBILITY OF THE CUSTODIAN. In performing its duties and obligations hereunder, the Custodian shall use reasonable care, prudence and diligence in carrying out the provisions of this Agreement, provided that the Custodian shall not be required to take any action that would be in contravention of Applicable Law. Subject to the specific provisions of this Section, the Custodian shall be liable for any direct damage or expense incurred by the Fund in consequence of the Custodian's negligence, bad faith or willful misconduct. In no event shall the Custodian be liable hereunder for any special or punitive damages or for losses attributable to the diminution in the enterprise value of the Fund or damage to reputation arising out of, pursuant to or in connection with this Agreement even if the Custodian has been advised of the possibility of such damages. It is agreed that the Custodian shall have no duty to assess the risks inherent in the Fund's Investments or to provide investment advice with respect to such Investments and that the Fund as principal shall bear any risks attendant to particular Investments such as failure of counterparty or issuer.

9.1 LIMITATIONS OF PERFORMANCE. The Custodian shall not be responsible under this Agreement for any failure to perform its duties, and shall not be liable hereunder for any loss or damage in association with such failure to perform, for or in consequence of the following causes:

FUNDS TRANSFER SERVICES SCHEDULE TO CUSTODIAN AGREEMENT

1. EXECUTION OF PAYMENT ORDERS. Brown Brothers Harriman & Co. (the Custodian) is hereby instructed by Pioneer Investment Management, Inc. (the Company) to execute each payment order, whether denominated in United States dollars or other applicable currencies, received by the Custodian in the Company's name as sender and authorized and confirmed by an Authorized Person as defined in a Custodian Agreement dated as of July 1, 2001 by and between the Custodian and the Company, as amended or restated from time thereafter (the Agreement), provided that the Company has sufficient available funds on deposit in a Principal Account as defined in the Agreement and provided that the order (i) is received by the Custodian in the manner specified in this Funds Transfer Services Schedule or any amendment hereafter; (ii) complies with any written instructions and restrictions of the Company as set forth in this Funds Transfer Services Schedule or any amendment hereafter; (iii) is authorized by the Company or is verified by the Custodian in compliance with a security procedure set forth in Paragraph 2 below for verifying the authenticity of a funds transfer communication sent to the Custodian in the name of the Company or for the detection of errors set forth in any such communication; and (iv) contains sufficient data to enable the Custodian to process such transfer.

2. SECURITY PROCEDURE. The Company hereby elects to use the procedure selected below as its security procedure (the Security Procedure). The Security Procedure will be used by the Custodian to verify the authenticity of a payment order or a communication amending or canceling a payment order. The Custodian will act on instructions received provided the instruction is authenticated by the Security Procedure. The Company agrees and acknowledges in connection with (i) the size, type and frequency of payment orders normally issued or expected to be issued by the Company to the Custodian, (ii) all of the security procedures offered to the Company by the Custodian, and (iii) the usual security procedures used by customers and receiving banks similarly situated, that authentication through the Security Procedure shall be deemed commercially reasonable for the authentication of all payment orders submitted to the Custodian. The Company hereby elects (PLEASE CHOOSE ONE) the following Security Procedure as described below:

[ ] BIDS AND BIDS WORLDVIEW PAYMENT PRODUCTS. BIDS and BIDS Worldview

Payment Products, are on-line payment order authorization facilities with built-in authentication procedures. The Custodian and the Company shall each be responsible for maintaining the confidentiality of passwords or other codes to be used by them in connection with BIDS. The Custodian will act on instructions received through BIDS without duty of further confirmation unless the Company notifies the Custodian that its password is not secure.

[X] SWIFT. Primary Method the Custodian and the Company shall comply with SWIFT's authentication procedures. The Custodian will act on instructions received via SWIFT provided the instruction is authenticated by the SWIFT system.

[ ] TESTED TELEX. The Custodian will accept payment orders sent by tested telex, provided the test key matches the algorithmic key the Custodian and Company have agreed to use.

[ ] COMPUTER TRANSMISSION. The Custodian is able to accept transmissions sent from the Company's computer facilities to the Custodian's computer facilities provided such transmissions are encrypted and digitally certified or are otherwise authenticated in a reasonable manner based on available technology. Such procedures shall be established in an operating protocol between the Custodian and the Company.

[X] TELEFAX INSTRUCTIONS. Back-Up Method A payment order transmitted to the Custodian by telefax transmission shall transmitted by the Company to a telephone number specified from time to time by the Custodian for such purposes. If it detects no discrepancies, the Custodian will then either:

1. If the telefax requests a repetitive payment order, the Custodian may call the Company at its last known telephone number, request to speak to the Company or Authorized Person, and confirm the authorization and the details of the payment order (a "Callback"); or

2. If the telefax requests a non-repetitive order, the Custodian will perform a Callback.

All faxes must be accompanied by a fax cover sheet which indicates the sender's name, company name, telephone number, fax number, number of pages, and number of transactions or instructions attached.

25

[ ] TELEPHONIC. Alternative Back-Up Method A telephonic payment order shall be called into the Custodian at the telephone number designated from time to time by the Custodian for that purpose. The caller shall identify herself/himself as an Authorized Person. The Custodian shall obtain the payment order data from the caller. The Custodian shall then:

1. If a telephonic repetitive payment order, the Custodian may perform a Callback; or

2. If a telephonic non-repetitive payment order, the Custodian will perform a Callback.

In the event the Company chooses a procedure which is not a Security Procedure as described above, the Company agrees to be bound by any payment order (whether or not authorized) issued in its name and accepted by the Custodian in compliance with the procedure selected by the Company.

3. REJECTION OF PAYMENT ORDERS. The Custodian shall give the Company timely notice of the Custodian's rejection of a payment order. Such notice may be given in writing or orally by telephone, each of which is hereby deemed commercially reasonable. In the event the Custodian fails to execute a properly executable payment order and fails to give the Company notice of the Custodian's non-execution, the Custodian shall be liable only for the Company's actual damages and only to the extent that such damages are recoverable under UCC 4A (as defined in Paragraph 7 below). Notwithstanding anything in this Funds Transfer Services Schedule and the Agreement to the contrary, the Custodian shall in no event be liable for any consequential or special damages under this Funds Transfer Services Schedule, whether or not such damages relate to services covered by UCC 4A, even if the Custodian has been advised of the possibility of such damages. Whenever compensation in the form of interest is payable by the Custodian to the Company pursuant to this Funds Transfer Services Schedule, such compensation will be payable at the rate specified in UCC 4A.

4. CANCELLATION OF PAYMENT ORDERS. The Company may cancel a payment order but the Custodian shall have no liability for the Custodian's failure to act on a cancellation instruction unless the Custodian has received such cancellation instruction at a time and in a manner affording the Custodian reasonable opportunity to act prior to the Custodian's execution of the order. Any cancellation shall be sent and confirmed in the manner set forth in Paragraph 2 above.

5. RESPONSIBILITY FOR THE DETECTION OF ERRORS AND UNAUTHORIZED PAYMENT ORDERS. Except as may be provided, the Custodian is not responsible for detecting any Company error contained in any payment order sent by the Company to the Custodian. In the event that the Company's payment order to the Custodian either
(i) identifies the beneficiary by both a name and an identifying or bank account number and the name and number identify different persons or entities, or (ii) identifies any bank by both a name and an identifying number and the number identifies a person or entity different from the bank identified by name, execution of the payment order, payment to the beneficiary, cancellation of the payment order or actions taken by any bank in respect of such payment order may be made solely on the basis of the number. The Custodian shall not be liable for interest on the amount of any payment order that was not authorized or was erroneously executed unless the Company so notifies the Custodian within thirty
(30) business days following the Company's receipt of notice that such payment order had been processed. If a payment order in the name of the Company and accepted by the Custodian was not authorized by the Company, the liability of the parties will be governed by the applicable provisions of UCC 4A.

6. LAWS AND REGULATIONS. The rights and obligations of the Custodian and the Company with respect to any payment order executed pursuant to this Funds Transfer Services Schedule will be governed by any applicable laws, regulations, circulars and funds transfer system rules, the laws and regulations of the United States of America and of other relevant countries including exchange control regulations and limitations on dealings or other sanctions, and including without limitation those sanctions imposed under the law of the United States of America by the Office of Foreign Assets Control. Any taxes, fines, costs, charges or fees imposed by relevant authorities on such transactions shall be for the account of the Company.

7. MISCELLANEOUS. All accounts opened by the Company or its authorized agents at the Custodian subsequent to the date hereof shall be governed by this Funds Transfer Schedule.

The terms and conditions of this Funds Transfer Services Schedule are in addition to, and do not modify or otherwise affect, the terms and conditions of the Agreement and any other agreement or arrangement between the parties hereto.

26

BY ELECTING TO SEND INSTRUCTIONS BY TELEFAX OR TELEPHONIC MEANS, THE COMPANY AGREES TO INDEMNIFY THE CUSTODIAN AND ITS PARTNERS, OFFICERS AND EMPLOYEES FOR ALL LOSSES THEREFROM.


OPTIONAL: The Custodian will perform a Callback if instructions are sent by telefax or telephonic means as provided in Paragraph 2. THE COMPANY MAY, AT ITS OWN RISK AND BY HEREBY AGREEING TO INDEMNIFY THE CUSTODIAN AND ITS PARTNERS, OFFICERS AND EMPLOYEES FOR ALL LOSSES THEREFROM OTHER THAN LOSSES RESULTING FROM THE CUSTODIANS OWN NEGLIGENCE OR WILLFUL DEFAULT, ELECT TO WAIVE A CALLBACK BY THE CUSTODIAN BY INITIALLING HERE:____

(b) CONTRACT ADMINISTRATION. The Delegate shall cause that the foreign custody arrangements with an Eligible Foreign Custodian shall be governed by a written contract that the Delegate

2

has determined will provide reasonable care for Fund assets based on the standards specified in paragraph (c)(1) of Rule 17f-5 under the 1940 Act . Each such contract shall, except as set forth in the last paragraph of this subsection (b), include provisions that provide:

(iii) That beneficial ownership of the Fund's Assets will be freely transferable without the payment of money or value other than for safe custody or administration;

ADMINISTRATION AGREEMENT

THIS ADMINISTRATION AGREEMENT dated this 1st day of April, 2002 between the Pioneer High Income Trust (the "Fund") and Pioneer Investment Management, Inc., a Delaware corporation (the "Manager").

W I T N E S S E T H

WHEREAS, the Fund is registered as a closed-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"), and has filed with the Securities and Exchange Commission (the "Commission") a registration statement (the "Registration Statement") for the purpose of registering its shares for public offering under the Securities Act of 1933, as amended (the "1933 Act");

WHEREAS, the parties hereto are parties to a Management Contract dated the date hereof (the "Management Contract");

WHEREAS, the Management Contract provides that the Manager will bear all of the Fund's expenses other than those provided in Section 2(c) and 2(d) of the Management Contract;

WHEREAS, Section 2(c)(i) provides that the Fund shall pay charges and expenses for Fund accounting, pricing and appraisal services and related overhead, including, to the extent that such services were performed by personnel of the Manager or its affiliates, office space and facilities, and personnel compensation, training and benefits;

WHEREAS, Section 2(c)(vi) and (vii) provide that the Fund shall pay (i) fees and expenses involved in registering and maintaining registrations of the Fund and/or its shares with the Commission, state or blue sky securities agencies and foreign countries, including the preparation of prospectuses and statements of additional information for filing with the Commission and (ii) all expenses of shareholders and Trustees' meetings and of preparing, printing and distributing prospectuses, notices, proxy statements and all reports to shareholders and to governmental agencies;

WHEREAS, the Manager intends to appoint a sub-administrator to perform some of its obligations under this Agreement and the parties do not intend that the Fund compensate the Manager for the services of the sub-administrator separately from the compensation under the Management Contract; and

WHEREAS, certain of these activities, as set forth on Exhibit 1 hereto, can be performed by members of the Manager's legal, accounting and administrative staff working at the direction and under the supervision of the Board of Trustees and Fund counsel.

NOW THEREFORE, in consideration of the mutual covenants and benefits set forth herein, the Fund and the Manager do hereby agree as follows:

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

2. The Fund authorizes the Manager to assist with the performance of the legal services listed on Exhibit 1 hereto (the "Legal Services"). The Legal Services shall at all times be subject to the supervision and direction of the Board of Trustees and Fund counsel.

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

4. In consideration of its services under this Agreement, the Manager shall be entitled to be reimbursed for the allocable portion of the direct costs of the Bookkeeping Services and the Legal Expenses (collectively, the "Services"); provided, however, if the Manager elects to retain a sub-administrator to perform any Bookkeeping Services, the Manager shall not be entitled to reimbursement of any fees paid to the sub-administrator for such services and shall only be entitled, as to Bookkeeping Services, for its direct costs incurred in connection with (i) any Bookkeeping Services actually performed by the Manager and (ii) its supervision of the services rendered by the sub-administrator. Such allocation shall be based upon the proportion of personnel time devoted to the Services authorized to be performed on behalf of the Fund to the total time worked by such personnel, in each case as estimated in good faith by the Manager and reviewed and approved annually by the Board of Trustees. Subject to the proviso above, direct costs shall include any out-of-pocket expenses of the Manager incurred in connection with the Services, the salaries and benefits of personnel of the Manager who are engaged in the Services pursuant to this Agreement and, with respect to the Services, a reasonable allocation of overhead (to the extent permitted under the Management Contract) associated with the performance of the Bookkeeping Services. The Manager shall estimate such direct costs and overhead (as appropriate) in good faith and the Fund shall be entitled to such supporting information as the Trustees shall reasonably request from time to time. Reimbursements paid hereunder to the Fund shall be subject to annual approval of the Board of Trustees.

5. Neither the Manager nor any sub-administrator shall be liable to the Fund for any action taken or omitted to be taken by it in connection with the performance of any of the Manager's duties or obligations under this Agreement, and the Fund shall indemnify the Manager and any sub-administrator and hold them harmless from and against all damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) incurred by the Manager or any sub-administrator in or by reason of any pending, threatened or contemplated action, suit, investigation or other proceeding (including an action or suit by or in the right of the Fund or its security holders) arising out of or otherwise based upon any action actually or allegedly taken or omitted to be taken by the Manager or any sub-administrator in connection with the performance of any of the Manager's duties or obligations under this Agreement; provided, however, that nothing contained herein shall protect or be deemed to protect the Manager or any sub-administrator against or entitle or be deemed to entitle the Manager or any sub-administrator to indemnification in respect of any liability to the Fund or its security holders to which the Manager or any sub-administrator would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of the Manager's duties, or by reason of its reckless disregard of the Manager's duties and obligations under this Agreement. Such expenses shall be paid by the Fund in advance of the final disposition of such matter upon invoice by the Manager or any sub-administrator and receipt by the Fund of an undertaking from the Manager or any sub-administrator to repay such amounts if it shall ultimately be established that the Manager or any sub-administrator is not entitled to payment of such expenses hereunder.

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

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

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

9. This Agreement and all performance hereunder shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts.

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

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

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

     United States dollars (which may be based on information provided by a
     pricing service) and expenses borne by the Trust, the Trust management
     letter to stockholders and such other information necessary for the
     Administrator to prepare the above referenced reports and filings, and the
     Administrator shall be entitled to rely on the accuracy and completeness of
     such information in performing its duties hereunder.

     All services are to be furnished through the medium of any officer or
     employee of the Administrator as the Administrator deems appropriate in
     order to fulfill its obligations hereunder.

     Each party shall bear all its own expenses incurred in connection with this
     Agreement. Printing and dissemination expenses, such as those for reports

2.   COMPENSATION OF THE ADMINISTRATOR.  PIM will pay the Administrator a fee
     on the first business day of each calendar month for the previous month
     equal to the greater of (i) $120,000 per annum ($10,000 per month), or (ii)
     at an annual rate equal to 0.10% of the Trust's Managed Assets (as
     hereinafter defined). For the purposes of determining fees payable to the
     Administrator, the value of the Trust's assets shall be computed at the
     times and in the manner specified in the Trust's registration statement on
     Form N-2, as amended from time to time (the "Registration Statement").
     Compensation by PIM to the Administrator shall commence on the date of the
     first receipt by the Trust of the proceeds of the sale of its shares to the
     underwriters as described in the Registration Statement, and the fee for
     the period from the date the Trust shall receive the proceeds of the sale
     of its shares to the underwriters as aforesaid to the end of the month
     during which such proceeds are so received, shall be pro-rated according to
     the proportion that such period bears to the full monthly period.  Upon
     termination of this Agreement before the end of a month, the fee for such
     part of that month shall be pro-rated according to the proportion that such
     periods bear to the full monthly period and shall be payable within seven
     days after the date of termination of this Agreement. "Managed Assets"
     means the average weekly value of the Trust's total assets minus the sum
     of the Trust's liabilities, which liabilities exclude debt relating to
     leverage, short-term debt and the aggregate liquidation preference of any
     outstanding preferred stock.

3.       LIMITATION OF LIABILITY OF THE ADMINISTRATOR, INDEMNIFICATION

(a)  The  Administrator  may,  with respect to  questions of law,  apply for and
     obtain the advice and  opinion of legal  counsel,  and with  respect to the
     application  of generally  accepted  accounting  principles  or Federal Tax
     accounting  principles,  apply for and obtain  the  advice  and  opinion of
     accounting  experts,  at the  reasonable  expense of the Trust or PIM.  The
     Administrator  shall  obtain  prior  permission  of the Trust or PIM before
     obtaining  the advise and  opinion  of legal or  accounting  experts at the
     expense of the Trust or PIM,  and shall not use any  counsel or  accounting
     experts  to  which  the  Trust  or  PIM  shall   reasonably   object.   The
     Administrator  shall be fully protected with respect to any action taken or
     omitted by it in good faith in conformity with this paragraph.

(b)  The  Administrator  shall not be liable to the Trust or PIM for any  action
     taken or omitted to be taken by the  Administrator  in connection  with the
     performance of any of its duties or obligations  under this Agreement,  and
     PIM shall indemnify the Administrator and hold it harmless from and against
     all  damages,   liabilities,   costs  and  expenses  (including  reasonable
     attorneys' fees and amounts reasonably paid in settlement)  incurred by the
     Administrator  in or by reason of any pending,  threatened or  contemplated
     action,  suit,  investigation or other  proceeding  (including an action or
     suit by or in the right of the Trust or its security  holders)  arising out
     of or  otherwise  based  upon any action  actually  or  allegedly  taken or
     omitted to be taken by the Administrator in connection with the performance
     of any  of its  duties  or  obligations  under  this  Agreement;  provided,
     however,  that  nothing  contained  herein  shall  protect  or be deemed to
     protect  the  Administrator  against or entitle or be deemed to entitle the
     Administrator  to  indemnification  in respect of any liability to PIM, the
     Trust or its security holders to which the Administrator would otherwise be
     subject by reason of willful misfeasance,  bad faith or gross negligence in
     the  performance of its duties,  or by reason of its reckless  disregard of
     its duties and  obligations  under this  Agreement.  Such expenses shall be
     paid by PIM in advance of the final disposition of such matter upon invoice
     by  the  Administrator  and  receipt  by  PIM of an  undertaking  from  the
     Administrator  to repay such amounts if it shall  ultimately be established
     that  the  Administrator  is not  entitled  to  payment  of  such  expenses
     hereunder.

(c) As used in this Paragraph 3, the term "Administrator" shall include any affiliates of the Administrator performing services for the Trust contemplated hereby, and trustees, officers, agents and employees of the Administrator or such affiliates.

Customer acknowledges that PIMSS intends to retain Mellon Investor Services LLC to act as its agent in providing the services set forth in Exhibit A hereto, provided that PIMSS shall be entitled, without Customer's prior consent to terminate Mellon Investor Services LLC and to appoint another subcontractor with respect to the services to be provided hereunder.

In no event will PIMSS be liable for special, indirect, incidental or consequential losses or damages of any kind whatsoever (including but not limited to lost profits), even if PIMSS has been advised of the possibility of such damages. Any liability of PIMSS will be limited in the aggregate to an amount equal to the fee paid by Customer during the preceding twelve (12) month period.

(ii) In the event any question or dispute arises with respect to PIMSS' duties hereunder, PIMSS shall not be required to act or be held liable or responsible for its failure or refusal to act until the question or dispute has been (i) judicially settled (and, if appropriate, PIMSS may file a suit in interpleader or for a declaratory judgment for such purpose) by final judgment rendered by a court of competent jurisdiction that is binding on all parties interested in the matter and is no longer subject to review or appeal, or (ii) settled by a written document in form and substance satisfactory to PIMSS and Customer and executed by Customer. In addition, PIMSS may require for such purpose, but shall not be obligated to require, the execution of such written settlement by parties that may have an interest in the settlement.

(b) INDEMNIFICATION. Customer shall indemnify PIMSS and its agents for, and hold it harmless against, any loss, liability, claim or expense ("Loss") arising out of or in connection with its duties under this Agreement or this appointment, including the costs and expenses of defending itself against any Loss or enforcing this Agreement, except to the extent that such Loss shall have been determined by a court of competent jurisdiction to be a result of the gross negligence or intentional misconduct of PIMSS or its agents.

PIMSS and its agents shall be entitled to seek advice of Customer's legal counsel with respect to PIMSS' responsibilities and duties hereunder and shall in no event be liable to Customer for any action taken pursuant to such advice, except to the extent that Customer's legal counsel determines in its sole discretion that the rendering of advice to PIMSS would result in a conflict of interest.

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

Customer agrees to indemnify and hold PIMSS, its employees, agents and nominees harmless from any and all claims, demands, actions and suits, whether groundless or otherwise, and from and against any and all judgments, liabilities, losses, damages, costs, charges, counsel fees and other expenses of every nature and character arising out of or in any way relating to PIMSS' action or non-action upon information, instructions or requests given or made to PIMSS by Customer with respect to the Account.

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

EXPENSES AND OTHER CHARGES

FEES AND OUT OF POCKET EXPENSES: The cost of stationery and supplies, including but not limited to transfer sheets, dividend checks, envelopes, and paper stock, together with any disbursement for telephone, postage, mail insurance, travel for annual meeting, link-up charges for ADP and tape charges from DTC are billed in addition to the above fees. All charges and fees, out of pocket costs, expenses and disbursements of Mellon are due and payable by Client upon receipt of an invoice from Mellon.

With respect to any shareholder mailing processed by Mellon, client shall, at least one business day prior to mail date, provide immediately available funds sufficient to cover all postage due on such mailing. For any dividend mailing, client shall, at least one business day prior to the mail date, also provide immediately available funds sufficient to pay the aggregate amount of dividends to be paid.

If Client participates in the Direct Registration System, Mellon will provide a "sell" feature for liquidation of book-entry shares held on behalf of a shareholder. Upon receipt of a sell request by the registered shareholder, Mellon Bank, N.A. will process the request and remit the proceeds to the shareholder in the form of a check (less the appropriate fees). The charge for each such sale is $15.00 plus $0.12 per share or, if applicable, the fees quoted in the Client's stock purchase and / or dividend reinvestment plan.

OFFERING ADMINISTRATION FEE: A minimum fee of $5,000 will be imposed for activities associated with initial public offerings (IPO's), secondary offerings and / or closings. The fee covers the coordination of efforts necessary between Mellon, the Client's underwriters, the banknote company and DTC in order to effect the closing. This fee will cover the issuance of up to 200 certificates and /or book-entry credits. Certificates and / or book-entry credits over this amount will be billed at $2.00 each. This fee is in addition to any fees Mellon may charge for coordination of selling shareholders, custody services and / or escrow services.

CONVERSION: There may be a charge for converting the Client's files to Mellon's system. Mellon will review the conversion requirements to determine if extraordinary efforts will be required to complete the conversion, such as account history conversion or file format conversion. Any charge will be discussed with the Client prior to work commencing. In addition, if an out-of-proof condition exists at the time of conversion, and such condition is not resolved within 90 days of such conversion, Client agrees to provide Mellon with funds or shares sufficient to resolve the out-of-proof condition promptly after the 90th day.

DECONVERSION FEE: In the event Client requests that Mellon provide records to a successor agent, in connection with the expiration or termination of this Agreement, Client shall pay Mellon a fee for deconversion services (e.g., providing shareholder lists and files, producing and shipping records, answering successor agent inquiries). This fee will be based on Mellon's then-current deconversion fee schedule. Mellon may withhold the Client's records, reports and unused certificate stock from a successor agent pending the Client's payment in full of all fees and expenses owed to Mellon under this Agreement.

LEGAL, TECHNOLOGICAL EXPENSES: Certain expenses may be incurred in resolving legal matters that arise in the course of performing services hereunder. This may result in a separate charge to cover Mellon's expenses (including the cost of external or internal counsel) in resolving such matters. Client agrees to reimburse Mellon for such expenses provided that any legal expenses charged to the Client relate directly and solely to Client legal matters and shall be reasonable.

In the event any Federal regulation and/or state or local laws are enacted which require Mellon to make any technological improvements and/or modifications to its current system, Client shall compensate Mellon, on a pro rata basis proportionate to the Client's registered shareholder base, for reasonable costs associated with making such required technological improvements and/or modifications; provided that Mellon use its best efforts to seek Client's approval at least 120 days' in advance of any such, such approval not to be unreasonably withheld.

Ladies and Gentlemen:

Pioneer High Income Trust (the "Trust") was established as a Delaware business trust under an Agreement and Declaration of Trust dated January 30, 2002 (the "Declaration of Trust"). The beneficial interests thereunder are represented by transferable shares of beneficial interest, no par value.

The Trustees have the powers set forth in the Declaration of Trust, subject to the terms, provisions and conditions therein provided. Pursuant to Article V, Section 2 of the Declaration of Trust, the number of shares of beneficial interest authorized to be issued under the Declaration of Trust is unlimited and the Trustees are authorized to divide the shares into one or more series of shares and one or more classes thereof as they deem necessary or desirable. Pursuant to Article V, Section 3 of the Declaration of Trust, the Trustees are empowered in their discretion to issue shares of any series for such amount and type of consideration, including cash or securities, and on such terms as the Trustees may authorize, all without action or approval of the shareholders. As of the date of this opinion, the Trustees have divided the shares of the Trust into one class of shares.

We have examined the Declaration of Trust and By-Laws, each as amended from time to time, of the Trust, and such other documents as we have deemed necessary or appropriate for the purposes of this opinion, including, but not limited to, originals, or copies certified or otherwise identified to our satisfaction, of such documents, Trust records and other instruments. In our examination of the above documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as certified of photostatic copies.

Any reference to "our knowledge", to any matter "known to us", "coming to our attention" or "of which we are aware" or any variation of any of the foregoing shall mean the conscious awareness of the attorneys in this firm who have rendered substantive attention to the preparation of the Trust's Registration Statement on Form N-2 or any amendments thereto, of the existence or absence of any facts which would contradict the opinions set forth below. We have not undertaken any independent investigation to determine the existence or absence of such facts, and no inference as to our knowledge of the existence or absence of such facts should be drawn from the fact of our representation of the Trust. Without limiting the foregoing, we have not examined any dockets or

records of any court, administrative tribunal or other similar entity, or any electronic or computer databases, in connection with our opinions expressed below.

Our opinions below are qualified to the extent that they may be subject to or affected by (i) applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting the rights and remedies of creditors generally, (ii) statutory or decisional law concerning recourse by creditors to security in the absence of notice or hearing and (iii) duties and standards imposed on creditors and parties to contracts, including, without limitation, requirements of good faith, reasonableness and fair dealing. Further, we do not express any opinion as to (i) the availability of the remedy of specific performance or any other equitable remedy upon breach of any provision of any agreement whether applied by a court of law or equity, (ii) the successful assertion of any equitable defense, or (iii) the right of any party to enforce the indemnification or contribution provisions of any agreement.

In rendering the opinion below, insofar as it relates to the good standing and valid existence of the Trust, we have relied solely on a certificate of the Secretary of State of the State of Delaware, dated as of a recent date, and such opinion is limited accordingly and is rendered as of the date of such certificate.

This opinion is limited to the Delaware Business Trust Act, and we express no opinion with respect to the laws of any other jurisdiction or to any other laws of the State of Delaware. Further, we express no opinion as to compliance with any state or federal securities laws, including the securities laws of the State of Delaware.

Our opinion below, as it relates to the non-assessability of the shares of the Trust, is qualified to the extent that any shareholder is, was or may become a named Trustee of the Trust. It is also qualified to the extent that, pursuant to Section 2 of Article VIII of the Declaration of Trust, the Trustees have the power to cause shareholders, or shareholders of a particular series, to pay certain custodian, transfer, servicing or similar agent charges by setting off the same against declared but unpaid dividends or by reducing share ownership (or by both means).

Subject to the foregoing, we are of the opinion that the Trust is a duly organized and validly existing business trust in good standing under the laws of the State of Delaware and that the shares of beneficial interest of the Trust, when issued in accordance with the terms, conditions, requirements and procedures set forth in the Declaration of Trust, the Trust's Registration Statement on Form N-2 and the Underwriting Agreement between the Trust and Merrill Lynch Pierce Fenner & Smith, Incorporated, as representatives of the underwriters named therein, will constitute legally and validly issued, fully paid and non-assessable shares of beneficial interest in the Trust, subject to compliance with the Securities Act of 1933, as amended, the Investment Company Act of 1940, as amended, and the applicable state laws regulating the sale of securities.

We are opining only as to the specific legal issues expressly set forth herein, and no opinion should be inferred as to any other matters. We are opining on the date hereof as to the law in effect on the date hereof, and we disclaim any obligation to advise you of any change in any of these sources of law or subsequent legal or factual developments that might affect any matters or opinions set forth herein.
