Dear Shareowner,
--------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. They
are particularly useful guides to keep in mind today, at a time when markets
around the globe are being buffeted by problems in the financial and real estate
industries and by concerns about a slowing economy.

After an extended period of steady growth with sustained low unemployment and
low inflation, the U.S. economy ran into difficulty as 2007 drew to a close.
Problems in the financial system tied to poor practices in the mortgage
financing industry and the end of home price appreciation have forced investors
and bankers to mark down the value of assets on their balance sheets. A
late-summer credit crunch forced central banks in the U.S. and Europe to assume
the role of "lender of last resort" to keep credit markets functioning as a
number of hedge funds faced margin calls and, in March, broker Bear Stearns
failed. As the repercussions of the credit crunch and falling home prices were
felt in the real economy, unemployment rose and consumer confidence fell.
Inflation concerns have moved to the back burner for the U.S. Federal Reserve,
which lowered interest rates, first gradually, then more rapidly, as concern
grew that falling home prices and disruptions in financial markets posed a
significant threat to economic growth.

Markets have reacted poorly to these developments, with fixed-income credit
spreads (the difference in rates between corporate and U.S. government bonds)
widening dramatically and stock markets declining, wiping out much of the
positive returns markets had delivered in the preceding year. For the 12 months
ending March 31, 2008, the Dow Jones Industrial Average rose 2%, the Standard &
Poor's 500 Index declined 5%, the NASDAQ Composite Index fell 6%, and the MSCI
EAFE Developed Market Index of international stock markets fell 2%. Over the
12-month period, the MSCI Emerging Markets Index was a standout performer,
rising 22%. The U.S. investment-grade bond market, as measured by the Lehman
Brothers Aggregate Bond Index, rose 8% over the 12 months ending March 31, 2008.
The U.S. high-yield bond market, as measured by the Merrill Lynch High Yield
Bond Master II Index, fell approximately 3.5% over the 12 months ending March
31, 2008, as its higher coupon yields could not offset a fall in bond prices
triggered by widening credit spreads.

As you may know, the turmoil in the credit markets has translated into liquidity
problems for auction-rate preferred securities, which has been well documented
in the media. Five of Pioneer's six closed-end mutual funds are leveraged using
those securities. Pioneer is actively working to find a resolution to the
problems. We are considering a number of potential solutions. As we work through
the issues associated with auction-rate preferred shares, we intend to provide


2


Letter


shareholders with periodic updates on market conditions and any developments
affecting the shares.

Looking forward, a growing number of economists are concerned about a recession.
As always, though, emotions can get ahead of reality. The U.S. economy grew in
the fourth quarter of 2007 and appears to have grown in the first quarter of
2008. Higher mortgage defaults, a spreading of weakness to other consumer
sectors or to employment, and the possibility of a worsening of the
liquidity/credit crunch represent risks to the economy. Conversely, substantial
fiscal and monetary stimulus programs have been put in place, economic growth in
the rest of the world remains relatively positive, and a weak U.S. dollar has
significantly benefited U.S. companies competing in the global marketplace.
While falling risk tolerances and deleveraging may continue to depress asset
prices in the short term, equity and corporate bond valuations look reasonable
unless the U.S. economy falls into a severe recession.

Sudden swings in the markets are always to be expected. The history of the stock
market demonstrates that sharp market downturns are frequently followed by
strong recoveries, but they are also difficult to time. Just as staying
diversified and invested are important investment principles, it is also
important to pay attention to asset allocation. As always, we encourage you to
work closely with your financial advisor to find the mix of stocks, bonds and
money market assets that is best aligned to your particular risk tolerance and
investment objective.

Respectfully,

[Signature of Daniel K. Kingsbury]

Pioneer High Income Trust

--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 3/31/08
--------------------------------------------------------------------------------

Growing problems in the credit markets, precipitated by a crisis in subprime
mortgages, undermined the performance of high-yield bonds during the 12 months
ending March 31, 2008. As the period progressed, fixed-income investors sought
out the highest-quality securities and tried to minimize credit risk exposure.
The following is an interview with Andrew Feltus, who discusses the performance
of Pioneer High Income Trust during the 12-month period. Mr. Feltus, a member of
Pioneer's fixed-income team, is responsible for the daily management of the
Trust.

Q:   How did the Trust perform during the 12 months ended March 31, 2008?

A:   Pioneer High Income Trust produced a total return of -7.42% at net asset
     value during the 12 months. At market price, the Trust returned -15.37%.
     During the same 12-month period, the Trust's benchmark, the Merrill Lynch
     High Yield Master II Index, returned -3.51%. At the end of the fiscal year,
     on March 31, 2008, the Trust's 30-day SEC yield was 14.75%. During a time
     when high-yield bond values tended to decline, the Trust's use of leverage
     - or borrowing - to invest in high-yield bonds tended to hold back total
     return performance, relative to the benchmark index, which does not include
     leverage.

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

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

Q:   What were the principal factors that affected the Trust's performance over
     the 12 months?

A:   The investment environment actually favored high-yield corporate bonds in
     the early months of the period. Into the early summer of 2007, healthy
     economic growth and rising corporate profits provided a favorable backdrop
     for lower-rated, high-yield bonds. As high-yield prices rose, the yield
     spreads between lower-rated corporate bonds and Treasuries tightened
     further, leading to


4


Pioneer High Income Trust

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

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

     outperformance by higher-yielding debt. In June, however, the emerging
     crisis in subprime mortgages started affecting credit markets generally,
     with a loss of liquidity that undercut the valuations of high-yield bonds.
     Yield spreads widened as major financial institutions reported that they
     were writing down the values of subprime debt that they had been holding,
     causing a drying up of liquidity for credit in general. Moreover, new
     leveraged buyout deals included many that involved unusually high
     proportions of debt or leverage. As the credit conditions worsened, the
     values of the resulting bonds tended to slip, and it was not unusual to see
     a 20%-to-30% decline in the valuations of some bonds tied to leveraged
     buyout deals just six months after their issuance. All this encouraged a
     general flight to quality, favoring Treasuries and other high-rated
     securities. And yet, despite the disappointing performance by high-yield
     corporate bonds during this period, the default rate for high-yield issues
     remained low by historical measures -- just 1.5% of the high-yield market
     defaulted during the 12 months ending March 31, 2008.

     To inject more cash or liquidity into the financial markets and stabilize
     market conditions, the Federal Reserve ("Fed") became increasingly
     aggressive in cutting the key Fed funds rate and making other policy
     decisions intended to free up more money for lending activities. In a
     series of actions from mid-September through the end of the Trust's fiscal
     year in March, the Fed cut the Fed funds rate from 5.25% to 2.25%.

     Pioneer High Income Trust under most circumstances uses leverage in pursuit
     of its goal of seeking high current income for its shareholders. This
     leveraged strategy typically works better when the high-yield market is
     performing well, with either stable or appreciating bond prices. The
     leveraged strategy, however, does not work as well when high-yield bond
     prices are retreating, as occurred in the final months of the fiscal year.
     This caused a further drag on Trust results. At the end of the fiscal year,
     leverage or borrowed money accounted for about 29% of assets. The Fund had
     no exposure to subprime mortgages during the period.


                                                                               5


Pioneer High Income Trust

--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 3/31/08                              (continued)
--------------------------------------------------------------------------------

Q:   Can you comment on the issues surrounding auction-rate preferred
     securities.

A:   The Trust has issued auction-rate preferred shares as a low-cost way of
     borrowing to provide leverage for the Trust. These auction-rate preferred
     shares typically have been traded at regularly scheduled auctions, giving
     investors in the preferred shares a source of financial liquidity while
     keeping the Trust's borrowing costs low. However, the aggravated problems
     in the credit markets have recently led to failed auctions for the
     preferred shares of many closed-end mutual funds, including Pioneer
     closed-end funds. Investors holding the preferred shares have been
     adversely affected because they have not had the ability to sell their
     shares at recent auctions. Meanwhile, the Trust must pay higher dividend
     rates on the preferred shares, consistent with the terms of documents
     authorizing issuance of preferred shares.

     Pioneer High Income Trust continues to pay all dividends in compliance with
     the terms of the auction-rate preferred share agreements. Further,
     auction-rate preferred shares issued by the Trust continue to be rated
     AAA/Aaa by Fitch and Moody's, the two principal credit rating agencies
     monitoring the Trust. Under current market conditions, the Trust's
     auction-rate preferred shares are an effective form of leverage. As market
     conditions change, that may not continue to be the case. Other forms of
     leverage may be more advantageous over the long term. Although the Trust
     may pursue obtaining alternative forms of leverage, there can be no
     assurance that it will be successful in doing so or that such leverage will
     be more effective than the auction-rate preferred shares.

Q:   Did you make any adjustments in strategy during this period?

A:   In the summer of 2007, we became increasingly selective in the types of
     high-yield bonds in which the Trust invested, raising the overall credit
     quality of bond holdings without compromising the income orientation of the
     Trust. We also began reducing the exposure to bonds of cyclical companies,
     including consumer cyclicals and industrial bonds whose revenues are more
     closely linked to the business cycle. We favored securities from
     non-cyclical industries, including the health care and non-cyclical
     consumer staples sectors. We also increased the Trust's investments in
     bonds from the energy sector and added catastrophe-linked bonds from the
     insurance


6


Pioneer High Income Trust

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

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

     industry. These insurance industry issues are securities whose risks are
     linked more to weather-related incidents than credit risk, and so their
     performance tends not to be correlated closely with economic cycles.

     At the end of the fiscal year, on March 31, 2008, the average credit
     quality of Trust holdings was B-. Approximately 67% of Trust assets were
     invested in domestic, high-yield corporate bonds, with almost 24% of assets
     invested in international high-yield and emerging market debt.
     Approximately 10% of assets were invested in domestic, investment-grade
     corporates on March 31, 2008.

Q:   What types of investments most affected Trust performance?

A:   The Trust's investments in catastrophe-linked bonds helped as the insurance
     industry experienced relatively modest claims from hurricanes and other
     storms during the 12 months. Individual investments that helped included
     bonds of Compucom (CRH Holdings), a computer services company. When
     Compucom was sold to another company, the bonds were called back at a
     premium to their most recent market price. Similarly, the Trust's
     investment in securities of Mirant Jamaica, a Jamaican utility, appreciated
     when that issuing company was acquired. The Trust's investment in
     securities of Mandra Forestry, a Chinese forestry company, also helped. The
     value of the company's debt rose as Mandra's performance improved and
     investors speculated that the company might be acquired. Among European
     holdings, securities issued by Norse Energy, a Norwegian exploration and
     production company, and by Kabel Deutschland, a cable communication
     services provider based in Germany, also appreciated in value during the
     period.

     Individual investments that detracted from results included securities of
     Angiotech Pharmaceuticals, Builders FirstSource, and Accuride. Angiotech,
     which produces drug-coated stents and other medical devices, struggled in
     an industry-wide slump. Builders FirstSource is a distributor who is
     heavily reliant on home builders as customers. The securities of Accuride,
     a manufacturer of truck parts, declined in price when capital spending by
     truck manufacturers weakened.


                                                                               7

PORTFOLIO MANAGEMENT DISCUSSION 3/31/08                              (continued)
--------------------------------------------------------------------------------

Q:   What is your investment outlook?

A:   Corporate high-yield bonds currently are selling at attractive valuations
     after several months in which the yield differentials between high-yield
     and Treasury securities have widened considerably. While fixed-income
     markets may continue to be volatile, especially because of unresolved
     issues in the investment banking and other industries, we believe investors
     currently are being well compensated for the credit risks of high-yield
     bonds.

     We think the economy is not likely to fall into a major recession, although
     it may enter a period of slow growth. At the same time, we should begin to
     see in the next few months the positive economic effects of the
     interest-rate cuts of the Federal Reserve and the tax rebates recently
     passed by Congress. Meanwhile the weak U.S. dollar and strong export
     activity should help support the overall economy until market conditions
     begin to stabilize and improve later in 2008.

     Overall, we believe the domestic high-yield market may offer interesting
     opportunities in the months ahead. While the problems in credit markets
     have adversely affected Trust borrowing costs, the back-up in yields of
     lower-rated corporates has strengthened the Trust's ability to maintain its
     dividend in the coming months.

     Investments in high-yield or lower-rated securities are subject to
     greater-than-average risk. The Trust may invest in securities of issuers
     that are in default or that are in bankruptcy.

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

     When interest rates rise, the prices of fixed-income securities in the
     Trust will generally fall. Conversely, when interest rates fall the prices
     of fixed-income securities in the Trust will generally rise. Investments in
     the Trust are subject to possible loss due to the financial failure of
     underlying securities and their inability to meet their debt obligations.

     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


8


Pioneer High Income Trust

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

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

     to do so and their market price is generally more volatile than that of
     more liquid securities. Illiquid securities are also more difficult to
     value and investment of the Trust's assets in illiquid securities may
     restrict the Trust's ability to take advantage of market opportunities.

     The Trust may use leverage through the issuance of preferred shares with an
     aggregate liquidation preference of up to 331/3% of the Trust's total
     assets after such issuance. Leverage creates significant risks, including
     the risk that the Trust's income or capital appreciation will not be
     sufficient to cover the cost of leverage, which may adversely affect the
     return for the holders of common shares.

     Risks of investing in the Trust are discussed in greater detail in the
     Trust's registration statement on Form N-2 relating to its common shares.

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

Performance data shown represents past performance. Past performance is no
guarantee of future results. Investment return and market price will fluctuate,
and your shares may trade below net asset value ("NAV"), due to such factors as
interest rate changes, and the perceived credit quality of borrowers.

Total investment return does not reflect broker sales charges or commissions.
All performance is for common shares of the Trust.

Closed-end funds, unlike open-end funds, are not continuously offered. There is
a one-time public offering and, once issued, shares of closed-end funds are sold
in the open market through a stock exchange and frequently trade at prices lower
than their NAV. NAV per common shares is total assets less total liabilities,
which includes preferred shares, divided by the number of common shares
outstanding.

When NAV is lower than market price, dividends are assumed to be reinvested at
the greater of NAV or 95% of the market price. When NAV is higher, dividends are
assumed to be reinvested at prices obtained under the Trust's dividend
reinvestment plan.

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

Index comparison begins April 30, 2002. The Merrill Lynch High Yield Master II
Index is a commonly accepted measure of the performance of high yield
securities. Index returns are calculated monthly, assume reinvestment of
dividends and, unlike Trust returns, do not reflect any fees, expenses or sales
charges. You cannot invest directly in the Index.

NOTES TO FINANCIAL STATEMENTS 3/31/08
--------------------------------------------------------------------------------

1. Organization and Significant Accounting Policies

Pioneer High Income Trust (the "Trust") was organized as a Delaware statutory
trust on January 30, 2002. Prior to commencing operations on April 26, 2002, the
Trust had no operations other than matters relating to its organization and
registration as a diversified, closed-end management investment company under
the Investment Company Act of 1940, as amended. The investment objective of the
Trust is to seek a high level of current income and the Trust may seek capital
appreciation to the extent that it is consistent with its investment objective.

The Trust's investments in certain foreign markets or countries with limited
developing markets may subject the Trust to a greater degree of risk than in a
developed market. These risks include disruptive political or economic
conditions and the possible imposition of adverse governmental laws or currency
exchange restrictions.

Information regarding the Trust's principal risks is contained in the Trust's
original offering prospectus, with additional information included in the
Trust's Shareowner reports from time to time. Please refer to those documents
when considering the Trust's risks. At times, the Trust's investments may
represent industries or industry sectors that are interrelated or have common
risks, making it more susceptible to any economic, political, or regulatory
developments or other risks affecting those industries or sectors. Under normal
market conditions, the Trust invests at least 80% of its assets in below
investment grade (high-yield) debt securities, loans and preferred stocks.
Because the Trust's investments will be concentrated in the 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.

The Trust's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Trust to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, and the reported amounts of income,
expenses and gains and losses on investments during the reporting year. Actual
results could differ from those estimates.

The following is a summary of significant accounting policies followed by the
Trust in the preparation of its financial statements, which are


                                                                              35


Pioneer High Income Trust

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/08                                (continued)
--------------------------------------------------------------------------------

consistent with those policies generally accepted in the investment company
industry:

A.   Security Valuation

     Security transactions are recorded as of trade date. Investments in Loan
     Interests are valued in accordance with guidelines established by the Board
     of Trustees at the mean between the last available bid and asked prices
     from one or more brokers or dealers as obtained from Loan Pricing
     Corporation. For the limited number of Loan Interests for which no reliable
     price quotes are available, such investments will be valued by Loan Pricing
     Corporation through the use of pricing matrices to determine valuations.

     Fixed-income securities are valued at prices supplied by independent
     pricing services, which consider such factors as Treasury spreads, yields,
     maturities and ratings. Valuations may be supplemented by values obtained
     from dealers and other sources, as required. Equity securities are valued
     at the last sale price on the principal exchanges where they are traded.
     Securities or Loan Interests for which market quotations are not readily
     available are valued using fair value methods pursuant to procedure adopted
     by the Board of Trustees. Trading in foreign securities is substantially
     completed each day at various times prior to the close of the NYSE. The
     values of such securities used in computing the net asset value of the
     Trust's shares are determined as of such times. The Trust may also use the
     fair value of a security, including a non-U.S. security, when the closing
     market price on the primary exchange where the security is traded no longer
     accurately reflects the value of the security as of the close of the
     exchange. As of March 31, 2008, the Trust had no fair valued securities.
     Temporary cash investments are valued at amortized cost which approximates
     market value.

     Dividend income is recorded on the ex-dividend date, except that certain
     dividends from foreign securities where the ex-dividend date may have
     passed are recorded as soon as the Trust becomes aware of the ex-dividend
     data in the exercise of reasonable diligence. Discounts and premiums on
     debt securities are accreted or amortized, respectively, daily, on an
     effective yield to maturity basis and are included in interest income.
     Premiums and discounts related to certain mortgage-backed securities are
     amortized or accreted in proportion to the monthly paydowns. Interest
     income,


36


Pioneer High Income Trust

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

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

     including income on interest bearing cash accounts, is recorded on an
     accrual basis.

     Gains and losses on sales of investments are calculated on the identified
     cost method for both financial reporting and federal income tax purposes.

B.   Foreign Currency Translation

     The books and records of the Trust are maintained in U.S. dollars. Amounts
     denominated in foreign currencies are translated into U.S. dollars using
     current exchange rates.

     Net realized gains and losses on foreign currency transactions represent,
     among other things, the net realized gains and losses on foreign currency
     contracts, disposition of foreign currencies and the difference between the
     amount of income accrued and the U.S. dollars actually received. Further,
     the effects of changes in foreign currency exchange rates on investments
     are not segregated in the Statement of Operations from the effects of
     changes in market prices of those securities but are included with the net
     realized and unrealized gain or loss on investments.

C.   Forward Foreign Currency Contracts

     The Trust enters into forward foreign currency contracts ("contracts") for
     the purchase or sale of a specific foreign currency at a fixed price on a
     future date as a hedge or cross-hedge against either specific investment
     transactions (settlement hedges) or portfolio positions (portfolio hedges).
     All contracts are marked to market daily at the applicable exchange rates,
     and any resulting unrealized gains or losses are recorded in the Trust's
     financial statements. The Trust records realized gains and losses at the
     time a portfolio hedge is offset by entry into a closing transaction or
     extinguished by delivery of the currency. Risks may arise upon entering
     into these contracts from the potential inability of counterparties to meet
     the terms of the contracts and from unanticipated movements in the value of
     foreign currencies relative to the U.S. dollar (see Note 5).


                                                                              37

NOTES TO FINANCIAL STATEMENTS 3/31/08                                (continued)
--------------------------------------------------------------------------------

D.   Federal Income Taxes

     It is the Trust's policy to comply with the requirements of the Internal
     Revenue Code applicable to regulated investment companies and to distribute
     all of its taxable income and net realized capital gains, if any, to its
     shareowners. Therefore, no federal income tax provision is required. Tax
     years prior to 2004 are closed (not subject to examination by Tax
     authorities) due to expiration of statute of limitations; all other tax
     years are open.

     The amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with federal
     income tax rules. Therefore, the sources of the Trust's distributions may
     be shown in the accompanying financial statements as either from or in
     excess of net investment income or net realized gain (loss) on investment
     and foreign currency transactions, or from paid-in capital, depending on
     the type of book/tax differences that may exist.

     As of March 31, 2008, the Trust reclassified $944,662 to decrease
     undistributed net investment income and to decrease net realized loss on
     investments. The reclassification has no impact on the net asset value of
     the Trust and presents the Trust's capital accounts on a tax basis.

     The tax character of distributions paid to common and preferred shareowners
     during the years ended March 31, 2008 and March 31, 2007 was as follows:

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


     The difference between book basis and tax basis unrealized depreciation is
     primarily attributable to the tax deferral of losses on straddles and wash
     sales, the realization for tax purposes of unrealized gains on investments
     in passive foreign investment companies, the realization for tax purposes
     of unrealized losses on certain foreign currency contracts, the difference
     between book and tax amortization methods for premiums and discounts on
     fixed income securities, the deferral of post-October capital losses and
     other book/tax temporary differences.

E.   Repurchase Agreements

     With respect to repurchase agreements entered into by the Trust, the value
     of the underlying securities (collateral), including accrued interests
     received from counterparties, is required to be at least equal to or in
     excess of the repurchase price at the time of purchase. The collateral for
     all repurchase agreements is held in safekeeping in the customer-only
     account of the Trust's custodian or subcustodians. Pioneer Investment
     Management, Inc., the Trust's investment adviser, is responsible for
     determining that the value of the collateral remains at least equal to the
     repurchase price.

F.   Securities Lending

     The Trust lends securities in its portfolio to certain broker-dealers or
     other institutional investors, with the Trust's custodian acting as the
     lending agent. When entering into a loan, the Trust receives collateral
     which is maintained by the custodian and earns income in the form of
     negotiated lenders' fees. The Trust also continues to receive interest or
     payments in lieu of dividends on the securities loaned. Unrealized gain or
     loss on the fair value of the loaned securities that may occur during the
     term of the loan will be for the account of the Trust. The loans are
     secured by collateral of at least 102%, at all times, of the fair value of
     the securities loaned. The


                                                                              39

     amount of the collateral will be adjusted daily to reflect any price
     fluctuation in the value of the loaned securities. The Trust has the right
     under the securities lending arrangement to recover the securities on loan
     from the borrower on demand. The Trust invests cash collateral in the
     Securities Lending Investment Fund which is sponsored by Brown Brothers
     Harriman & Co., the Trust's custodian.

G.   Automatic Dividend Reinvestment Plan

     All common shareowners automatically participate in the Automatic Dividend
     Reinvestment Plan (the "Plan"), under which participants receive all
     dividends and capital gain distributions (collectively, "dividends") in
     full and fractional common shares of the Trust in lieu of cash. Shareowners
     may elect not to participate in the Plan. Shareowners not participating in
     the Plan receive all dividends and capital gain distributions in cash.
     Participation in the Plan is completely voluntary and may be terminated or
     resumed at any time without penalty by notifying American Stock Transfer &
     Trust Company, the agent for shareowners in administering the Plan (the
     "Plan Agent"), in writing prior to any dividend record date; otherwise such
     termination or resumption will be effective with respect to any
     subsequently declared dividend or other distribution.

     Whenever the Trust declares a dividend on common shares payable in cash,
     participants in the Plan will receive the equivalent in common shares
     acquired by the Plan Agent either (i) through receipt of additional
     unissued but authorized common shares from the Trust or (ii) by purchase of
     outstanding common shares on the New York Stock Exchange or elsewhere. If,
     on the payment date for any dividend, the net asset value per common share
     is equal to or less than the market price per share plus estimated
     brokerage trading fees ("market premium"), the Plan Agent will invest the
     dividend amount in newly issued common shares. The number of newly issued
     common shares to be credited to each account will be determined by dividing
     the dollar amount of the dividend by the net asset value per common 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 does not
     exceed 5%. If, on the payment date for any dividend, the net asset value
     per common share is greater than the market value ("market discount"), the
     Plan Agent will invest the dividend amount in common shares acquired in
     open-market purchases. There are no


40


Pioneer High Income Trust

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

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

     brokerage charges with respect to newly issued common shares. However, each
     participant will pay a pro rata share of brokerage trading fees incurred
     with respect to the Plan Agent's open-market purchases. Participating in
     the Plan does not relieve shareowners from any federal, state or local
     taxes which may be due on dividends paid in any taxable year. Shareowners
     holding Plan shares in a brokerage account may not be able to transfer the
     shares to another broker and continue to participate in the Plan.

2. Management Agreement

Pioneer Investment Management, Inc. ("PIM"), a wholly owned indirect subsidiary
of UniCredito Italiano S.p.A. ("UniCredito Italiano") manages the Trust's
portfolio. Management fees payable under the Trust's Advisory Agreement with PIM
are calculated daily at the annual rate of 0.60% of the Trust's average weekly
managed assets. "Managed assets" is the average daily value of the Trust's total
assets minus the sum of the Trust's liabilities, which liabilities exclude debt
related to leverage, short-term debt and the aggregate liquidation preference of
any outstanding preferred shares. For the year ended March 31, 2008, the net
management fee was equivalent to 0.60% of the Trust's average weekly managed
assets, which was equivalent to 0.82% of the Trust's average daily net assets
attributable to the common shareowners.

In addition, under PIM's management and administration agreements, certain other
services and costs are paid by PIM and reimbursed by the Trust. At March 31,
2008, $270,182 was payable to PIM related to management costs, administrative
costs and certain other services and is in included in "Due to affiliates" on
the Statement of Assets and Liabilities.

PIM has retained Princeton Administrators, LLC ("Princeton") to provide certain
administrative and accounting services to the Trust on its behalf. PIM pays
Princeton a monthly fee at an annual rate of 0.07% of the average daily value of
the Trust's managed assets up to $500 million and 0.03% for average daily
managed assets in excess of $500 million, subject to a minimum monthly fee of
$10,000. Princeton receives no compensation directly from the Trust.


                                                                              41

3. Transfer Agents

Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly
owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency
agreement with American Stock Transfer & Trust Company, provides substantially
all transfer agent and shareowner services related to the Trust's common shares
at negotiated rates. Deutsche Bank Trust Company Americas ("Deutsche Bank") is
the transfer agent, registrar, dividend paying agent and auction agent with
respect to the Trust's Auction Market Preferred Shares ("AMPS"). The Trust pays
Deutsche Bank an annual fee, as is agreed to from time to time by the Trust and
Deutsche Bank, for providing such services.

4. Expense Offset Arrangements

The Trust has entered into an arrangement with its custodian whereby credits
realized as a result of uninvested cash balances are used to reduce a portion of
the Trust's custodian expenses. For the year ended March 31, 2008, the Trust
expenses were reduced by $28 under such arrangement.

5. Forward Foreign Currency Contracts

The Trust may enter into contracts that obligate the Trust to deliver currencies
at specified future dates. At the maturity of a contract, the Trust must make
delivery of the specified currency. Alternatively, prior to the settlement date
of these hedges, the Trust may close out such contracts by entering into
offsetting hedge contract.

Open portfolio hedges at March 31, 2008 were as follows:

6. Trust Shares

There are an unlimited number of common shares of beneficial interest
authorized.

Transactions in common shares of beneficial interest for the years ended March
31, 2008 and March 31, 2007 were as follows:



-----------------------------------------------------------------------------
                                        2008            2007

  Shares outstanding at
    beginning of year               27,093,609     26,931,420
  Reinvestment of distributions        133,833        162,189

  Shares outstanding at
    end of year                     27,227,442     27,093,609
                                    ==========     ==========
-----------------------------------------------------------------------------


The Trust may classify or reclassify any unissued common shares of beneficial
interest into one or more series of preferred shares of beneficial interest. As
of March 31, 2008, there were 6,040 AMPS as follows: Series M7-2,020, Series
W28-2,020 and Series TH7-2,000.

Dividends on Series M7 and Series TH7 are cumulative at a rate which is reset
every seven days based on the results of an auction. An auction fails if there
are more AMPS offered than there are buyers. When an auction fails, the dividend
rate for the period will be the maximum rate on the auction dates described in
the prospectus for the AMPS. You will not be able to sell your AMPS at an
auction if the auction fails. Since February 13, 2008, the Trust's auctions
related to the AMPS have failed. The maximum rate for the 7-Day Series is 150%
of the 7 Day commercial paper rate. The maximum rate for the 28 day Series is
150% of the 30 day commercial paper rate. Dividends on Series W28 are also
cumulative at a rate reset every 28 days based on the results of an auction.
Dividend rates ranged from 3.00% to 6.50% during the year ended March 31, 2008.

The Trust may not declare dividends or make other distributions on its common
shares or purchase any such shares if, at the time of the declaration,
distribution or purchase, asset coverage with respect to the outstanding
preferred shares would be less than 200%.

The AMPS are redeemable at the option of the Trust, in whole or in part, on any
dividend payment date at $25,000 per share plus any accumulated or unpaid
dividends, whether or not declared. The AMPS


                                                                              43

NOTES TO FINANCIAL STATEMENTS 3/31/08                                (continued)

are also subject to mandatory redemption at $25,000 per share plus any
accumulated or unpaid dividends, whether or not declared, if certain
requirements relating to the composition of the assets and liabilities of the
Trust as set forth in the Agreement and Declaration of Trust are not satisfied.

The holders of AMPS have voting rights equal to the holders of the Trust's
common shares (one vote per share) and will vote together with holders of the
common shares as a single class. However, holders of AMPS are also entitled to
elect two of the Trust's Trustees. In addition, the Investment Company Act of
1940, as amended, requires that along with approval by shareowners 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
(a) adopt any plan of reorganization that would adversely affect the preferred
shares and (b) take any action requiring a vote of security holders, including,
among other things, changes in the Trust's subclassification as a closed-end
management investment company or changes in its fundamental investment
restrictions.

7. New Pronouncements

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements ("SFAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Trust's financial statement disclosures.

In March 2008, Statement of Financial Accounting Standards No. 161, Disclosures
about Derivative Instruments and Hedging Activities ("SFAS 161"), was issued and
is effective for fiscal years beginning after November 15, 2008. SFAS 161
requires enhanced disclosures about an entity's derivative and hedging
activities. Management is currently evaluating the impact the adoption of SFAS
161 will have on the Trust's financial statement disclosures.

Company Act of 1940 that the Trust may purchase, from time to time, its common
shares in the open market.

Additional Information Regarding the Trust's Investment Policies

Event-Linked Bonds

The Trust may invest in "event-linked" bonds, which sometimes are referred to as
"insurance-linked" or "catastrophe" bonds. Event-linked bonds are debt
obligations for which the return of principal and the payment of interest are
contingent on the non-occurrence of a pre-defined "trigger" event, such as a
hurricane or an earthquake of a specific magnitude. For some event-linked bonds,
the trigger event's magnitude


                                                                              45


Pioneer High Income Trust

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/08                                (continued)
--------------------------------------------------------------------------------

may be based on losses to a company or industry, industry indexes or readings of
scientific instruments rather than specified actual losses. If a trigger event,
as defined within the terms of an event-linked bond, involves losses or other
metrics exceeding a specific magnitude in the geographic region and time period
specified therein, the Trust may lose a portion or all of its accrued interest
and/or principal invested in such event-linked bond. The Trust is entitled to
receive principal and interest payments so long as no trigger event occurs of
the description and magnitude specified by the instrument.

Event-linked bonds may be issued by government agencies, insurance companies,
reinsurers, special purpose corporations or other on-shore or off-shore
entities. In addition to the specified trigger events, event-linked bonds may
also expose the Trust to other risks, including but not limited to issuer
(credit) default, adverse regulatory or jurisdictional interpretations and
adverse tax consequences. Event-linked bonds are subject to the risk that the
model used to calculate the probability of a trigger event was not accurate and
underestimated the likelihood of a trigger event. Upon the occurrence or
possible occurrence of a trigger event, and until the completion of the
processing and auditing of applicable loss claims, the Trust's investment in
such event-linked bond may be priced using fair value methods. As a relatively
new type of financial instrument, there is limited trading history for these
securities, and there can be no assurance that a more liquid market in these
instruments will develop.

Event-linked bonds typically are rated by at least one nationally recognized
rating agency, but also may be unrated. The rating for an event-linked bond
primarily reflects the rating agency's calculated probability that a pre-defined
trigger event will occur. This rating also assesses the event-linked bond's
credit risk and model used to calculate the probability of a trigger event.

CEO CERTIFICATION DISCLOSURE (unaudited)

The Trust's Chief Executive Officer has submitted to the New York Stock Exchange
the annual CEO certification as required by Section 303A.12(a) of the NYSE
Listed Company Manual. In addition, the Trust has filed with the Securities and
Exchange Commission the certification of its Chief Executive Officer and Chief
Financial Officer required by Section 302 of the Sarbanes-Oxley Act.

--------------------------------------------------------------------------------
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------

To the Board of Trustees and the Shareowners of
Pioneer High Income Trust:

We have audited the accompanying statement of assets and liabilities of Pioneer
High Income Trust (the "Trust"), including the schedule of investments, as of
March 31, 2008, and the related statement of operations for the year then ended,
the statements of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the five years in the
period then ended. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Trust's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Trust's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of March 31, 2008, by correspondence with the custodian,
selling or agent banks and brokers or by other appropriate auditing procedures
where replies from brokers were not received. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Trust at March 31, 2008, the results of its operations for
the year then ended, the changes in its net assets for each of the two years in
the period then ended, and the financial highlights for each of the five years
in the period then ended, in conformity with U.S. generally accepted accounting
principles.

APPROVAL OF INVESTMENT ADVISORY AGREEMENT
--------------------------------------------------------------------------------

Pioneer Investment Management, Inc. ("PIM") serves as the Trust's investment
adviser pursuant to an investment advisory agreement between PIM and the Trust.
The Trustees of the Trust, as required by law, determine annually whether to
continue the investment advisory agreement for the Trust.

In connection with their most recent consideration of the investment advisory
agreement for the Trust, the Trustees received and reviewed a substantial amount
of information provided by PIM in response to requests of the independent
Trustees and their independent legal counsel. The independent Trustees met on a
number of occasions with PIM and also separately with their independent legal
counsel to evaluate and discuss the information provided to them by PIM. At a
meeting held on November 13, 2007, based on their evaluation of the information
provided by PIM, the Trustees, including the independent Trustees voting
separately, unanimously approved the continuation of the investment advisory
agreement for another year.

In considering the continuation of the investment advisory agreement, the
Trustees considered various factors that they determined were relevant,
including the factors described below. The Trustees did not identify any single
factor as the controlling factor in determining to approve the continuation of
the agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services provided
by PIM to the Trust, taking into account the investment objective and strategy
of the Trust and the information related to the Trust provided to the Trustees
at each quarterly meeting. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for the
Trust and its research process. The Trustees considered the resources of PIM and
the personnel of PIM who provide investment management services to the Trust.
They also considered PIM's compliance and legal resources and personnel.

In addition, the Trustees considered the other services that PIM provides to the
Trust under the investment advisory agreement and that, as administrator, PIM is
responsible for the administration of the Trust's business and other affairs. It
was noted that PIM supervises and monitors the performance of the Trust's
service providers and provides the Trust with personnel (including officers) as
are necessary

for the Trust's operations. The Trustees considered the fees paid to PIM for the
provision of such services.

Based on these considerations, the Trustees concluded that the nature, extent
and quality of services provided by PIM to the Trust were satisfactory and
consistent with the terms of the investment advisory agreement.

Performance of the Trust

The Trustees considered the performance results of the Trust over various time
periods. They reviewed information comparing the Trust's performance with the
average performance of its peer group of funds as classified by Morningstar,
Inc. ("Morningstar"), an independent provider of investment company data, and
with the performance of the Trust's benchmark index. The Trustees considered
that the Trust's annualized total return was in the first quintile of its
Morningstar category for the one, three and five year periods ended June 30,
2007. (In all quintile rankings referred to throughout this disclosure, first
quintile is most favorable to the Trust's shareowners. Thus, highest relative
performance would be first quintile and lowest relative expenses would also be
first quintile.) The Trustees concluded that the investment performance of the
Trust was satisfactory.

Management Fee and Expenses

The Trustees considered information on the fees and expenses of the Trust in
comparison to the management fees and the expense ratios of a peer group of
funds selected on the basis of criteria determined by the independent Trustees
for this purpose using data provided by Strategic Insight Mutual Fund Research
and Consulting, LLC ("Strategic Insight"), an independent third party.

The Trustees considered that the Trust's management fee for the twelve months
ended June 30, 2007 was in the first quintile relative to the management fees
paid by other funds in its Strategic Insight peer group for the comparable
period. The Trustees also considered that the Trust's expense ratio for the
twelve months ended June 30, 2007 was in the first quintile relative to its
Strategic Insight peer group. It was noted that PIM did not currently manage any
separate accounts with an investment objective and strategies that were similar
to the Trust.

The Trustees concluded that the management fee payable by the Trust to PIM was
reasonable in relation to the nature and quality of


                                                                              51

services provided, taking into account the fees charged by other advisers for
managing comparable funds with similar strategies. The Trustees also concluded
that the Trust's expense ratio was reasonable, taking into account the size of
the Trust, the quality of services provided by PIM and the investment
performance of the Trust.

Profitability

The Trustees considered information provided by PIM regarding the profitability
of PIM with respect to the advisory services provided by PIM to the Trust,
including the methodology used by PIM in allocating certain of its costs to the
management of the Trust. The Trustees also considered PIM's profit margin in
connection with the overall operation of the Trust. They further reviewed the
financial results realized by PIM and its affiliates from non-Trust businesses.
The Trustees considered PIM's profit margins with respect to the Trust in
comparison to the limited industry data available and noted that the
profitability of any adviser was affected by numerous factors, including its
organizational structure and method for allocating expenses. The Trustees
recognized that PIM should be entitled to earn a reasonable level of profit for
the services provided to the Trust. The Trustees concluded that PIM's
profitability with respect to the management of the Trust was not unreasonable.

Economies of Scale

The Trustees considered the extent to which PIM may realize economies of scale
or other efficiencies in managing and supporting the Trust. Since the Trust is a
closed-end fund and its size is relatively stable at an asset level that was
anticipated when the management fee was initially set, the majority of the
Trustees concluded that economies of scale were not a relevant consideration.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with the
Trust. The Trustees considered that an affiliate of PIM serves as the Trust's
transfer agent. The Trustees further considered the intangible benefits to PIM
by virtue of its relationship with the Trust and the other Pioneer funds. The
Trustees concluded that the receipt of these benefits was reasonable in the
context of the overall relationship between PIM and the Trust.

Conclusion

After consideration of the factors described above as well as other factors, the
Trustees, including all of the independent Trustees, concluded that the terms of
the investment advisory agreement between PIM and the Trust, including the fees
payable thereunder, were fair and reasonable and voted to approve the proposed
continuation of the investment advisory agreement for the Trust.

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

GENERAL AUDIT COMMITTEE APPROVAL POLICY:
o For all projects, the officers of the Funds and the Fund's auditors will each
  make an assessment to determine that any proposed projects will not impair
  independence.

o Potential services will be classified into the four non-restricted service
  categories and the "Approval of Audit, Audit-Related, Tax and Other
  Services" Policy above will be applied. Any services outside the specific
  pre-approved service subcategories set forth above must be specifically
  approved by the Audit Committee.

o At least quarterly, the Audit Committee shall review a report summarizing the
  services by service category, including fees, provided by the Audit firm as
  set forth in the above policy.

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


    (2) Disclose the percentage of services described in each of paragraphs (b)
   through (d) of this Item that were approved by the audit committee pursuant
   to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

Beginning with non-audit service contracts entered into on or
after May 6, 2003, the effective date of the new SEC pre-
approval rules, the Trust's audit committee is required to pre-
approve services to affiliates defined by SEC rules to the
extent that the services are determined to have a direct impact
on the operations or financial reporting of the Trust. For the
years ended March 31, 2008 and 2007, there were no services
provided to an affiliate that required the Trust's audit
committee pre-approval.

(f) If greater than 50 percent, disclose the percentage of hours expended on the
principal accountant's engagement to audit the registrant's financial statements
for the most recent fiscal year that were attributed to work performed by
persons other than the principal accountant's full-time, permanent employees.

N/A

(g) Disclose the aggregate non-audit fees billed by the registrant's accountant
for services rendered to the registrant, and rendered to the registrant's
investment adviser (not including any sub-adviser whose role is primarily
portfolio management and is subcontracted with or overseen by another investment
adviser), and any entity controlling, controlled by, or under common control
with the adviser that provides ongoing services to the registrant for each of
the last two fiscal years of the registrant.

The aggregate non-audit fees for the Trust and affiliates, as
previously defined, totaled approximately $17,105 in 2008 and
$16,440 in 2007.


(h) Disclose whether the registrant's audit committee of the board of trustees
has considered whether the provision of non-audit services that were rendered to
the registrant's investment adviser (not including any subadviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the investment adviser that provides ongoing services to the
registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of
Rule 2-01 of Regulation S-X is compatible with maintaining the principal
accountant's independence.

The Fund's audit committee of the Board of Trustees has
considered whether the provision of non-audit services that
were rendered to the Affiliates (as defined) that were not pre-
approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of
Regulation S-X is compatible with maintaining the principal
accountant's independence.

Item 5. Audit Committee of Listed Registrants

(a) If the registrant is a listed issuer as defined in Rule 10A-3
under the Exchange Act (17 CFR 240.10A-3), state whether
or not the registrant has a separately-designated standing
 audit committee established in accordance with Section
3(a)(58)(A) of the Exchange Act (15 U.S.C. 78c(a)(58)(A)).
If the registrant has such a committee, however designated,
identify each committee member. If the entire board of directors
is acting as the registrants audit committee as specified in
Section 3(a)(58)(B) of the Exchange Act (15 U.S.C. 78c(a)(58)(B)),
so state.

Proxy Voting Policies and Procedures of
                       Pioneer Investment Management, Inc.

                            VERSION DATED July, 2004

                                    Overview

   Pioneer Investment Management, Inc. ("Pioneer") is a fiduciary that owes
   each of its client's duties of care and loyalty with respect to all
   services undertaken on the client's behalf, including proxy voting. When
   Pioneer has been delegated proxy-voting authority for a client, the duty of
   care requires Pioneer to monitor corporate events and to vote the proxies.
   To satisfy its duty of loyalty, Pioneer must place its client's interests
   ahead of its own and must cast proxy votes in a manner consistent with the
   best interest of its clients. Pioneer will vote all proxies presented in a
   timely manner.

   The Proxy Voting Policies and Procedures are designed to complement
   Pioneer's investment policies and procedures regarding its general
   responsibility to monitor the performance and/or corporate events of
   companies that are issuers of securities held in accounts managed by
   Pioneer. Pioneer's Proxy Voting Policies summarize Pioneer's position on a
   number of issues solicited by companies held by Pioneer's clients. The
   policies are guidelines that provide a general indication on how Pioneer
   would vote but do not include all potential voting scenarios.

   Pioneer's Proxy Voting Procedures detail monitoring of voting, exception
   votes, and review of conflicts of interest and ensure that case-by-case
   votes are handled within the context of the overall guidelines (i.e. best
   interest of client). The overriding goal is that all proxies for US and
   non-US companies that are received promptly will be voted in accordance
   with Pioneer's policies or specific client instructions. All shares in a
   company held by Pioneer-managed accounts will be voted alike, unless a
   client has given us specific voting instructions on an issue or has not
   delegated authority to us or the Proxy Voting Oversight Group determines
   that the circumstances justify a different approach.

   Pioneer does not delegate the authority to vote proxies relating to its
   clients to any of its affiliates, which include other subsidiaries of
   UniCredito.

   Any questions about these policies and procedures should be directed to the
   Proxy Coordinator.

                                       1


                             Proxy Voting Procedures

   Proxy Voting Service
   Pioneer has engaged an independent proxy voting service to assist in the
   voting of proxies. The proxy voting service works with custodians to ensure
   that all proxy materials are received by the custodians and are processed
   in a timely fashion. To the extent applicable, the proxy voting service
   votes all proxies in accordance with the proxy voting policies established
   by Pioneer. The proxy voting service will refer proxy questions to the
   Proxy Coordinator (described below) for instructions under circumstances
   where: (1) the application of the proxy voting guidelines is unclear; (2) a
   particular proxy question is not covered by the guidelines; or (3) the
   guidelines call for specific instructions on a case-by-case basis. The
   proxy voting service is also requested to call to the Proxy Coordinator's
   attention specific proxy questions that, while governed by a guideline,
   appear to involve unusual or controversial issues. Pioneer reserves the
   right to attend a meeting in person and may do so when it determines that
   the company or the matters to be voted on at the meeting are strategically
   important to its clients.

   Proxy Coordinator
   Pioneer's Director of Investment Operations (the "Proxy Coordinator")
   coordinates the voting, procedures and reporting of proxies on behalf of
   Pioneer's clients. The Proxy Coordinator will deal directly with the proxy
   voting service and, in the case of proxy questions referred by the proxy
   voting service, will solicit voting recommendations and instructions from
   the Director of Portfolio Management US or, to the extent applicable,
   investment sub-advisers. The Proxy Coordinator is responsible for ensuring
   that these questions and referrals are responded to in a timely fashion and
   for transmitting appropriate voting instructions to the proxy voting
   service. The Proxy Coordinator is responsible for verifying with the
   Compliance Department whether Pioneer's voting power is subject to any
   limitations or guidelines issued by the client (or in the case of an
   employee benefit plan, the plan's trustee or other fiduciaries).

   Referral Items
   From time to time, the proxy voting service will refer proxy questions to
   the Proxy Coordinator that are described by Pioneer's policy as to be voted
   on a case-by-case basis, that are not covered by Pioneer's guidelines or
   where Pioneer's guidelines may be unclear with respect to the matter to be
   voted on. Under such certain circumstances, the Proxy Coordinator will seek
   a written voting recommendation from the Director of Portfolio Management
   US. Any such recommendation will include: (i) the manner in which the
   proxies should be voted; (ii) the rationale underlying any such decision;
   and (iii) the disclosure of any contacts or communications made between
   Pioneer and any outside parties concerning the proxy proposal prior to the
   time that the voting instructions are provided. In addition, the Proxy
   Coordinator will ask the Compliance Department to review the question for
   any actual or apparent conflicts of interest as described below under
   "Conflicts of

                                       2


   Interest." The Compliance Department will provide a "Conflicts of Interest
   Report," applying the criteria set forth below under "Conflicts of
   Interest," to the Proxy Coordinator summarizing the results of its review.
   In the absence of a conflict of interest, the Proxy Coordinator will vote
   in accordance with the recommendation of the Director of Portfolio
   Management US.

   If the matter presents a conflict of interest for Pioneer, then the Proxy
   Coordinator will refer the matter to the Proxy Voting Oversight Group for a
   decision. In general, when a conflict of interest is present, Pioneer will
   vote according to the recommendation of the Director of Portfolio
   Management US where such recommendation would go against Pioneer's interest
   or where the conflict is deemed to be immaterial. Pioneer will vote
   according to the recommendation of its proxy voting service when the
   conflict is deemed to be material and the Pioneer's internal vote
   recommendation would favor Pioneer's interest, unless a client specifically
   requests Pioneer to do otherwise. When making the final determination as to
   how to vote a proxy, the Proxy Voting Oversight Group will review the
   report from the Director of Portfolio Management US and the Conflicts of
   Interest Report issued by the Compliance Department.

   Conflicts of Interest
   A conflict of interest occurs when Pioneer's interests interfere, or appear
   to interfere with the interests of Pioneer's clients. Occasionally, Pioneer
   may have a conflict that can affect how its votes proxies. The conflict may
   be actual or perceived and may exist when the matter to be voted on
   concerns:

       o      An affiliate of Pioneer,  such as another company  belonging to
              the UniCredito  Italiano  S.p.A.  banking group (a "UniCredito
              Affiliate");

       o      An issuer of a security for which Pioneer acts as a sponsor,
              advisor, manager, custodian, distributor, underwriter, broker, or
              other similar capacity (including those securities specifically
              declared by PGAM to present a conflict of interest for Pioneer);

       o      An issuer of a security for which UniCredito has informed Pioneer
              that a UniCredito Affiliate acts as a sponsor, advisor, manager,
              custodian, distributor, underwriter, broker, or other similar
              capacity; or

       o      A person with whom Pioneer (or any of its affiliates) has an
              existing, material contract or business relationship that was not
              entered into in the ordinary course of Pioneer's business.

       o      Pioneer will abstain from voting with respect to companies
              directly or indirectly owned by UniCredito Italiano Group, unless
              otherwise directed by a client. In addition, Pioneer will inform
              PGAM Global Compliance and the PGAM Independent Directors before
              exercising such rights.

   Any associate involved in the proxy voting process with knowledge of any
   apparent or actual conflict of interest must disclose such conflict to the
   Proxy Coordinator and the Compliance Department. The Compliance Department
   will review each item referred to Pioneer to determine whether an actual or
   potential conflict of interest with Pioneer exists in connection with the
   proposal(s) to be voted upon. The review will be conducted by comparing the
   apparent parties affected by the proxy proposal being

                                       3


   voted upon against the Compliance Department's internal list of interested
   persons and, for any matches found, evaluating the anticipated magnitude
   and possible probability of any conflict of interest being present. For
   each referral item, the determination regarding the presence or absence of
   any actual or potential conflict of interest will be documented in a
   Conflicts of Interest Report to the Proxy Coordinator.

   Securities Lending
   In conjunction with industry standards Proxies are not available to be
   voted when the shares are out on loan through either Pioneer's lending
   program or a client's managed security lending program. However, Pioneer
   will reserve the right to recall lent securities so that they may be voted
   according to the Pioneer's instructions. If a portfolio manager would like
   to vote a block of previously lent shares, the Proxy Coordinator will work
   with the portfolio manager and Investment Operations to recall the
   security, to the extent possible, to facilitate the vote on the entire
   block of shares.

   Share-Blocking

   "Share-blocking" is a market practice whereby shares are sent to a
   custodian (which may be different than the account custodian) for record
   keeping and voting at the general meeting. The shares are unavailable for
   sale or delivery until the end of the blocking period (typically the day
   after general meeting date).

   Pioneer will vote in those countries with "share-blocking." In the event a
   manager would like to sell a security with "share-blocking", the Proxy
   Coordinator will work with the Portfolio Manager and Investment Operations
   Department to recall the shares (as allowable within the market time-frame
   and practices) and/or communicate with executing brokerage firm. A list of
   countries with "share-blocking" is available from the Investment Operations
   Department upon request.

   Record Keeping
   The Proxy Coordinator shall ensure that Pioneer's proxy voting service:

       o   Retains a copy of the proxy statement received (unless the proxy
           statement is available from the SEC's Electronic Data Gathering,
           Analysis, and Retrieval (EDGAR) system);

       o   Retains a record of the vote cast;

       o   Prepares Form N-PX for filing on behalf of each client that is a
           registered investment company; and

       o   Is able to promptly provide Pioneer with a copy of the voting
           record upon its request.

                                       4


   The Proxy Coordinator shall ensure that for those votes that may require
   additional documentation (i.e. conflicts of interest, exception votes and
   case-by-case votes) the following records are maintained:

       o    A record memorializing the basis for each referral vote cast;

       o    A copy of any document created by Pioneer that was material in
            making the decision on how to vote the subject proxy; and

       o    A copy of any conflict notice, conflict consent or any other
            written communication (including emails or other electronic
            communications) to or from the client (or in the case of an
            employee benefit plan, the plan's trustee or other fiduciaries)
            regarding the subject proxy vote cast by, or the vote
            recommendation of, Pioneer.

       o    Pioneer shall maintain the above records in the client's file for a
            period not less than ten (10) years.

     Disclosure
     Pioneer shall take reasonable measures to inform its clients of the process
     or procedures clients must follow to obtain information regarding how
     Pioneer voted with respect to assets held in their accounts. In addition,
     Pioneer shall describe to clients its proxy voting policies and procedures
     and will furnish a copy of its proxy voting policies and procedures upon
     request. This information may be provided to clients through Pioneer's Form
     ADV (Part II) disclosure, by separate notice to the client, or through
     Pioneer's website.

     Proxy Voting Oversight Group
     The members of the Proxy Voting Oversight Group are Pioneer's: Director of
     Portfolio Management US, Head of Investment Operations, and Director of
     Compliance. Other members of Pioneer will be invited to attend meetings and
     otherwise participate as necessary. The Head of Investment Operations will
     chair the Proxy Voting Oversight Group.

     The Proxy Voting Oversight Group is responsible for developing, evaluating,
     and changing (when necessary) Pioneer's Proxy Voting Policies and
     Procedures. The group meets at least annually to evaluate and review these
     policies and procedures and the services of its third-party proxy voting
     service. In addition, the Proxy Voting Oversight Group will meet as
     necessary to vote on referral items and address other business as
     necessary.

     Amendments
     Pioneer may not amend its Proxy Voting Policies And Procedures without the
     prior approval of the Proxy Voting Oversight Group and its corporate
     parent, Pioneer Global Asset Management S.p.A

                                       5


   Proxy Voting Policies
   Pioneer's sole concern in voting proxies is the economic effect of the
   proposal on the value of portfolio holdings, considering both the short-
   and long-term impact. In many instances, Pioneer believes that supporting
   the company's strategy and voting "for" management's proposals builds
   portfolio value. In other cases, however, proposals set forth by management
   may have a negative effect on that value, while some shareholder proposals
   may hold the best prospects for enhancing it. Pioneer monitors developments
   in the proxy-voting arena and will revise this policy as needed.

   All proxies that are received promptly will be voted in accordance with the
   specific policies listed below. All shares in a company held by
   Pioneer-managed accounts will be voted alike, unless a client has given us
   specific voting instructions on an issue or has not delegated authority to
   us. Proxy voting issues will be reviewed by Pioneer's Proxy Voting
   Oversight Group, which consists of the Director of Portfolio Management US,
   the Director of Investment Operations (the Proxy Coordinator), and the
   Director of Compliance.

   Pioneer has established Proxy Voting Procedures for identifying and
   reviewing conflicts of interest that may arise in the voting of proxies.

   Clients may request, at any time, a report on proxy votes for securities
   held in their portfolios and Pioneer is happy to discuss our proxy votes
   with company management. Pioneer retains a proxy voting service to provide
   research on proxy issues and to process proxy votes.

Administrative
   While administrative items appear infrequently in U.S. issuer proxies, they
   are quite common in non-U.S. proxies.

   We will generally support these and similar management proposals:

       o    Corporate name change.

       o    A change of corporate headquarters.

       o    Stock exchange listing.

       o    Establishment of time and place of annual meeting.

       o    Adjournment or postponement of annual meeting.

       o    Acceptance/approval of financial statements.

       o    Approval of dividend payments, dividend reinvestment plans and other
            dividend-related proposals.

       o    Approval of minutes and other formalities.

                                       6


       o    Authorization of the transferring of reserves and allocation of
            income.

       o    Amendments to authorized signatories.

       o    Approval of accounting method changes or change in fiscal year-end.

       o    Acceptance of labor agreements.

       o    Appointment of internal auditors.

   Pioneer will vote on a case-by-case basis on other routine business;
   however, Pioneer will oppose any routine business proposal if insufficient
   information is presented in advance to allow Pioneer to judge the merit of
   the proposal. Pioneer has also instructed its proxy voting service to
   inform Pioneer of its analysis of any administrative items inconsistent, in
   its view, with supporting the value of Pioneer portfolio holdings so that
   Pioneer may consider and vote on those items on a case-by-case basis.

Auditors
     We normally vote for proposals to:

       o    Ratify the auditors. We will consider a vote against if we are
            concerned about the auditors' independence or their past work for
            the company. Specifically, we will oppose the ratification of
            auditors and withhold votes from audit committee members if
            non-audit fees paid by the company to the auditing firm exceed the
            sum of audit fees plus audit-related fees plus permissible tax
            fees according to the disclosure categories proposed by the
            Securities and Exchange Commission.

       o    Restore shareholder rights to ratify the auditors.

     We will normally oppose proposals that require companies to:

       o    Seek bids from other auditors.

       o    Rotate auditing firms, except where the rotation is statutorily
            required or where rotation would demonstrably strengthen financial
            disclosure.

       o    Indemnify auditors.

       o    Prohibit auditors from engaging in non-audit services for the
            company.

     Board of Directors
     On issues related to the board of directors, Pioneer normally supports
     management. We will, however, consider a vote against management in
     instances where corporate performance has been very poor or where the board
     appears to lack independence.

                                       7


     General Board Issues
     Pioneer will vote for:

       o    Audit, compensation and nominating committees composed of
            independent directors exclusively.

       o    Indemnification for directors for actions taken in good faith in
            accordance with the business judgment rule. We will vote against
            proposals for broader indemnification.

       o    Changes in board size that appear to have a legitimate business
            purpose and are not primarily for anti-takeover reasons.

       o    Election of an honorary director.

     We will vote against:

       o    Minimum stock ownership by directors.

       o    Term limits for directors. Companies benefit from experienced
            directors, and shareholder control is better achieved through
            annual votes.

       o    Requirements for union or special interest representation on the
            board.

       o    Requirements to provide two candidates for each board seat.

     We will vote on a case-by case basis on these issues:

       o    Separate chairman and CEO positions. We will consider voting with
            shareholders on these issues in cases of poor corporate
            performance.

     Elections of Directors
     In uncontested elections of directors we will vote against:

       o    Individual directors with absenteeism above 25% without valid
            reason. We support proposals that require disclosure of director
            attendance.

       o    Insider directors and affiliated outsiders who sit on the audit,
            compensation, stock option or nominating committees. For the
            purposes of our policy, we accept the definition of affiliated
            directors provided by our proxy voting service.

     We will also vote against:

       o    Directors who have failed to act on a takeover offer where the
            majority of shareholders have tendered their shares.

       o    Directors who appear to lack independence or are associated with
            very poor corporate performance.

                                       8


     We will vote on a case-by case basis on these issues:

       o    Re-election of directors who have implemented or renewed a
            dead-hand or modified dead-hand poison pill (a "dead-hand poison
            pill" is a shareholder rights plan that may be altered only by
            incumbent or "dead " directors. These plans prevent a potential
            acquirer from disabling a poison pill by obtaining control of the
            board through a proxy vote).

       o    Contested election of directors.

       o    Prior to phase-in required by SEC, we would consider supporting
            election of a majority of independent directors in cases of poor
            performance.

       o    Mandatory retirement policies.

       o    Directors who have ignored a shareholder proposal that has been
            approved by shareholders for two consecutive years.

     Takeover-Related Measures
     Pioneer is generally opposed to proposals that may discourage takeover
     attempts. We believe that the potential for a takeover helps ensure that
     corporate performance remains high.

     Pioneer will vote for:

       o    Cumulative voting.

       o    Increase ability for shareholders to call special meetings.

       o    Increase ability for shareholders to act by written consent.

       o    Restrictions on the ability to make greenmail payments.

       o    Submitting rights plans to shareholder vote.

       o    Rescinding shareholder rights plans ("poison pills").

       o    Opting out of the following state takeover statutes:

     o Control share acquisition statutes, which deny large holders voting
       rights on holdings over a specified threshold.

     o Control share cash-out provisions, which require large holders to
       acquire shares from other holders.

     o Freeze-out provisions, which impose a waiting period on large
       holders before they can attempt to gain control.

     o Stakeholder laws, which permit directors to consider interests of
       non-shareholder constituencies.

                                       9


     o Disgorgement provisions, which require acquirers to disgorge profits
       on purchases made before gaining control.

     o Fair price provisions.

     o Authorization of shareholder rights plans.

     o Labor protection provisions.

     o Mandatory classified boards.

     We will vote on a case-by-case basis on the following issues:

       o    Fair price provisions. We will vote against provisions requiring
            supermajority votes to approve takeovers. We will also consider
            voting against proposals that require a supermajority vote to
            repeal or amend the provision. Finally, we will consider the
            mechanism used to determine the fair price; we are generally
            opposed to complicated formulas or requirements to pay a premium.

       o    Opting out of state takeover statutes regarding fair price
            provisions. We will use the criteria used for fair price
            provisions in general to determine our vote on this issue.

       o    Proposals that allow shareholders to nominate directors.

     We will vote against:

       o    Classified boards, except in the case of closed-end mutual funds.

       o    Limiting shareholder ability to remove or appoint directors. We
            will support proposals to restore shareholder authority in this
            area. We will review on a case-by-case basis proposals that
            authorize the board to make interim appointments.

       o    Classes of shares with unequal voting rights.

       o    Supermajority vote requirements.

       o    Severance packages ("golden" and "tin" parachutes). We will support
            proposals to put these packages to shareholder vote.

       o    Reimbursement of dissident proxy solicitation expenses. While we
            ordinarily support measures that encourage takeover bids, we
            believe that management should have full control over corporate
            funds.

       o    Extension of advance notice requirements for shareholder proposals.

       o    Granting board authority normally retained by shareholders (e.g.,
            amend charter, set board size).

       o    Shareholder rights plans ("poison pills"). These plans generally
            allow shareholders to buy additional shares at a below-market
            price in the event of a change in control and may deter some bids.

                                       10


     Capital Structure
     Managements need considerable flexibility in determining the company's
     financial structure, and Pioneer normally supports managements' proposals
     in this area. We will, however, reject proposals that impose high barriers
     to potential takeovers.

     Pioneer will vote for:

       o    Changes in par value.

       o    Reverse splits, if accompanied by a reduction in number of shares.

       o    Share repurchase programs, if all shareholders may participate on
            equal terms.

       o    Bond issuance.

       o    Increases in "ordinary" preferred stock.

       o    Proposals to have blank-check common stock placements (other than
            shares issued in the normal course of business) submitted for
            shareholder approval.

       o    Cancellation of company treasury shares.

     We will vote on a case-by-case basis on the following issues:

       o    Reverse splits not accompanied by a reduction in number of shares,
            considering the risk of delisting.

       o    Increase in authorized common stock. We will make a determination
            considering, among other factors:

     o Number of shares currently available for issuance;

     o Size of requested increase (we would normally approve increases of up to
       100% of current authorization);

     o Proposed use of the additional shares; and

     o Potential consequences of a failure to increase the number of shares
       outstanding (e.g., delisting or bankruptcy).

       o    Blank-check preferred. We will normally oppose issuance of a new
            class of blank-check preferred, but may approve an increase in a
            class already outstanding if the company has demonstrated that it
            uses this flexibility appropriately.

       o    Proposals to submit private placements to shareholder vote.

       o    Other financing plans.

     We will vote against preemptive rights that we believe limit a company's
financing flexibility.

                                      11


     Compensation
     Pioneer supports compensation plans that link pay to shareholder returns
     and believes that management has the best understanding of the level of
     compensation needed to attract and retain qualified people. At the same
     time, stock-related compensation plans have a significant economic impact
     and a direct effect on the balance sheet. Therefore, while we do not want
     to micromanage a company's compensation programs, we will place limits on
     the potential dilution these plans may impose.

     Pioneer will vote for:

       o    401(k) benefit plans.

       o    Employee stock ownership plans (ESOPs), as long as shares
            allocated to ESOPs are less than 5% of outstanding shares. Larger
            blocks of stock in ESOPs can serve as a takeover defense. We will
            support proposals to submit ESOPs to shareholder vote.

       o    Various issues related to the Omnibus Budget and Reconciliation Act
            of 1993 (OBRA), including:

     o Amendments to performance plans to conform with OBRA;

     o Caps on annual grants or amendments of administrative features;

     o Adding performance goals; and

     o Cash or cash-and-stock bonus plans.

       o    Establish a process to link pay, including stock-option grants, to
            performance, leaving specifics of implementation to the company.

       o    Require that option repricings be submitted to shareholders.

       o    Require the expensing of stock-option awards.

       o    Require reporting of executive retirement benefits (deferred
            compensation, split-dollar life insurance, SERPs, and pension
            benefits).

       o    Employee stock purchase plans where the purchase price is equal to
            at least 85% of the market price, where the offering period is no
            greater than 27 months and where potential dilution (as defined
            below) is no greater than 10%.

                                       12


     We will vote on a case-by-case basis on the following issues:

       o    Executive and director stock-related compensation plans. We will
            consider the following factors when reviewing these plans:

       o    The program must be of a reasonable size. We will approve plans
            where the combined employee and director plans together would
            generate less than 15% dilution. We will reject plans with 15% or
            more potential dilution.

            Dilution = (A + B + C) / (A + B + C + D), where

            A = Shares reserved for plan/amendment,

            B = Shares available under continuing plans,

            C = Shares granted but unexercised and

            D = Shares outstanding.

       o    The plan must not:

            o   Explicitly permit unlimited option repricing authority or that
                have repriced in the past without shareholder approval.

            o   Be a self-replenishing "evergreen" plan, plans that grant
                discount options and tax offset payments.

     o We are generally in favor of proposals that increase participation beyond
       executives.

     o We generally support proposals asking companies to adopt rigorous
       vesting provisions for stock option plans such as those that vest
       incrementally over, at least, a three- or four-year period with a pro
       rata portion of the shares becoming exercisable on an annual basis
       following grant date.

     o We generally support proposals asking companies to disclose their
       window period policies for stock transactions. Window period policies
       ensure that employees do not exercise options based on insider
       information contemporaneous with quarterly earnings releases and other
       material corporate announcements.

     o We generally support proposals asking companies to adopt stock holding
       periods for their executives.

       o    All other employee stock purchase plans.

       o    All other compensation-related proposals, including deferred
            compensation plans, employment agreements, loan guarantee programs
            and retirement plans.

       o    All other proposals regarding stock compensation plans, including
            extending the life of a plan, changing vesting restrictions,
            repricing options, lengthening exercise periods or accelerating
            distribution of awards and pyramiding and cashless exercise
            programs.

                                       13


     We will vote against:

       o    Pensions for non-employee directors. We believe these retirement
            plans reduce director objectivity.

       o    Elimination of stock option plans.

     We will vote on a case-by case basis on these issues:

       o    Limits on executive and director pay.

       o    Stock in lieu of cash compensation for directors.

     Corporate Governance
     Pioneer will vote for:

       o    Confidential Voting.

       o    Equal access provisions, which allow shareholders to contribute
            their opinion to proxy materials.

       o    Proposals requiring directors to disclose their ownership of shares
            in the company.

     We will vote on a case-by-case basis on the following issues:

       o    Change in the state of incorporation. We will support
            reincorporations supported by valid business reasons. We will
            oppose those that appear to be solely for the purpose of
            strengthening takeover defenses.

       o    Bundled proposals. We will evaluate the overall impact of the
            proposal.

       o    Adopting or amending the charter, bylaws or articles of association.

       o    Shareholder appraisal rights, which allow shareholders to demand
            judicial review of an acquisition price.

     We will vote against:

       o    Shareholder advisory committees. While management should solicit
            shareholder input, we prefer to leave the method of doing so to
            management's discretion.

       o    Limitations on stock ownership or voting rights.

       o    Reduction in share ownership disclosure guidelines.

                                       14


     Mergers and Restructurings
     Pioneer will vote on the following and similar issues on a case-by-case
     basis:

       o    Mergers and acquisitions.

       o    Corporate restructurings, including spin-offs, liquidations, asset
            sales, joint ventures, conversions to holding company and
            conversions to self-managed REIT structure.

       o    Debt restructurings.

       o    Conversion of securities.

       o    Issuance of shares to facilitate a merger.

       o    Private placements, warrants, convertible debentures.

       o    Proposals requiring management to inform shareholders of merger
            opportunities.

     We will normally vote against shareholder proposals requiring that the
     company be put up for sale.

     Mutual Funds
     Many of our portfolios may invest in shares of closed-end mutual funds or
     exchange-traded funds. The non-corporate structure of these investments
     raises several unique proxy voting issues.

     Pioneer will vote for:

       o    Establishment of new classes or series of shares.

       o    Establishment of a master-feeder structure.

     Pioneer will vote on a case-by-case on:

       o    Changes in investment policy. We will normally support changes
            that do not affect the investment objective or overall risk level
            of the fund. We will examine more fundamental changes on a
            case-by-case basis.

       o    Approval of new or amended advisory contracts.

       o    Changes from closed-end to open-end format.

       o    Authorization for, or increase in, preferred shares.

       o    Disposition of assets, termination, liquidation, or mergers.

       o    Classified boards of closed-end mutual funds, but will typically
            support such proposals.

                                       15


     Social Issues
     Pioneer will abstain on stockholder proposals calling for greater
     disclosure of corporate activities with regard to social issues. "Social
     Issues" may generally be described as shareholder proposals for a company
     to:

       o    Conduct studies regarding certain issues of public concern and
            interest;

       o    Study the feasibility of the company taking certain actions with
            regard to such issues; or

       o    Take specific action, including ceasing certain behavior and
            adopting company standards and principles, in relation to issues
            of public concern and interest.

     We believe these issues are important and should receive management
     attention.

     Pioneer will vote against proposals calling for substantial changes in the
     company's business or activities. We will also normally vote against
     proposals with regard to contributions, believing that management should
     control the routine disbursement of funds.

                                       16

Additional Information About the Portfolio Managers

Other Accounts Managed by the Portfolio Managers. The table below indicates, for
the portfolio manager of the fund, information about the accounts other than the
fund over which the portfolio manager has day-to-day investment responsibility.
All information on the number of accounts and total assets in the table is as of
March 31, 2008. For purposes of the table, "Other Pooled Investment Vehicles"
may include investment partnerships, undertakings for collective investments in
transferable securities ("UCITS") and other non-U.S. investment funds and group
trusts, and "Other Accounts" may include separate accounts for institutions or
individuals, insurance company general or separate accounts, pension funds and
other similar institutional accounts but generally do not include the portfolio
manager's personal investment accounts or those which the manager may be deemed
to own beneficially under the code of ethics. Certain funds and other accounts
managed by the portfolio manager may have substantially similar investment
strategies.

Potential Conflicts of Interest. When a portfolio manager is responsible for the
management of more than one account, the potential arises for the portfolio
manager to favor one account over another. The principal types of potential
conflicts of interest that may arise are discussed below. For the reasons
outlined below, Pioneer does not believe that any material conflicts are likely
to arise out of a portfolio manager's responsibility for the management of the
fund as well as one or more other accounts. Although Pioneer has adopted
procedures that it believes are reasonably designed to detect and prevent
violations of the federal securities laws and to mitigate the potential for
conflicts of interest to affect its portfolio management decisions, there can be
no assurance that all conflicts will be identified or that all procedures will
be effective in mitigating the potential for such risks. Generally, the risks of
such conflicts of interest are increased to the extent that a portfolio manager
has a financial incentive to favor one account over another. Pioneer has
structured its compensation arrangements in a manner that is intended to limit
such potential for conflicts of interest. See "Compensation of Portfolio
Managers" below.

o       A portfolio manager could favor one account over another in allocating
        new investment opportunities that have limited supply, such as initial
        public offerings and private placements. If, for example, an initial
        public offering was expected to appreciate in value significantly
        shortly after the offering was allocated to a single account, that
        account may be expected to have better investment performance than other
        accounts that did not receive an allocation of the initial public
        offering. Generally, investments for which there is limited availability
        are allocated based upon a range of factors including available cash and
        consistency with the accounts' investment objectives and policies. This
        allocation methodology necessarily involves some subjective elements but
        is intended over time to treat each client in an equitable and fair
        manner. Generally, the investment opportunity is allocated among
        participating accounts on a pro rata basis.  Although Pioneer believes
        that its practices are reasonably designed to treat each client in an
        equitable and fair manner, there may be instances where a fund may not
        participate, or may participate to a lesser degree than other clients,
        in the allocation of an investment opportunity.

o       A portfolio manager could favor one account over another in the order
        in which trades for the accounts are placed.  If a portfolio manager
        determines to purchase a security for more than one account in an
        aggregate amount that may influence the market price of the security,
        accounts that purchased or sold the security first may receive a more
        favorable price than accounts that made subsequent transactions. The
        less liquid the market for the security or the greater the percentage
        that the proposed aggregate purchases or sales represent of average
        daily trading volume, the greater the potential for accounts that make
        subsequent purchases or sales to receive a less favorable price. When a
        portfolio manager intends to trade the same security on the same day for
        more than one account, the trades typically are "bunched," which means
        that the trades for the individual accounts are aggregated and each
        account receives the same price.  There are some types of accounts as to
        which bunching may not be possible for contractual reasons (such as
        directed brokerage arrangements). Circumstances may also arise where the
        trader believes that bunching the orders may not result in the best
        possible price. Where those accounts or circumstances are involved,
        Pioneer will place the order in a manner intended to result in as
        favorable a price as possible for such client.

o       A portfolio manager could favor an account if the portfolio manager's
        compensation is tied to the performance of that account to a greater
        degree than other accounts managed by the portfolio manager.  If, for
        example, the portfolio manager receives a bonus based upon the
        performance of certain accounts relative to a benchmark while other
        accounts are disregarded for this purpose, the portfolio manager will
        have a financial incentive to seek to have the accounts that determine
        the portfolio manager's bonus achieve the best possible performance to
        the possible detriment of other accounts.  Similarly, if Pioneer
        receives a performance-based advisory fee, the portfolio manager may
        favor that account, whether or not the performance of that account
        directly determines the portfolio manager's compensation.

o       A portfolio manager could favor an account if the portfolio manager has
        a beneficial interest in the account, in order to benefit a large client
        or to compensate a client that had poor returns. For example, if the
        portfolio manager held an interest in an investment partnership that was
        one of the accounts managed by the portfolio manager, the portfolio
        manager would have an economic incentive to favor the account in which
        the portfolio manager held an interest.

o       If the different accounts have materially and potentially conflicting
        investment objectives or strategies, a conflict of interest could arise.
        For example, if a portfolio manager purchases a security for one account
        and sells the same security for another account, such trading pattern
        may disadvantage either the account that is long or short.  In making
        portfolio manager assignments, Pioneer seeks to avoid such potentially
        conflicting situations. However, where a portfolio manager is
        responsible for accounts with differing investment objectives and
        policies, it is possible that the portfolio manager will conclude that
        it is in the best interest of one account to sell a portfolio security
        while another account continues to hold or increase the holding in such
        security.


Compensation of Portfolio Managers. Pioneer has adopted a system of compensation
for portfolio managers that seeks to align the financial interests of the
portfolio managers with those of shareholders of the accounts (including Pioneer
funds) the portfolio managers manage, as well as with the financial performance
of Pioneer. The compensation program for all Pioneer portfolio managers includes
a base salary (determined by the rank and tenure of the employee) and an annual
bonus program, as well as customary benefits that are offered generally to all
full-time employees. Base compensation is fixed and normally reevaluated on an
annual basis. Pioneer seeks to set base compensation at market rates, taking
into account the experience and responsibilities of the portfolio manager. The
bonus plan is intended to provide a competitive level of annual bonus
compensation that is tied to the portfolio manager achieving superior investment
performance and align the interests of the investment professional with those of
shareholders, as well as with the financial performance of Pioneer. Any bonus
under the plan is completely discretionary, with a maximum annual bonus that may
be in excess of base salary. The annual bonus is based upon a combination of the
following factors:

o        Quantitative Investment Performance. The quantitative investment
         performance calculation is based on pre-tax investment performance
         of all of the accounts managed by the portfolio manager (which includes
         the fund and any other accounts managed by the portfolio manager) over
         a one-year period (20% weighting) and four-year period (80% weighting),
         measured for periods ending on December 31. The accounts, which include
         the fund, are ranked against a group of mutual funds with similar
         investment objectives and investment focus (60%) and a broad-based
         securities market index measuring the performance of the same type of
         securities in which the accounts invest (40%), which, in the case of
         the fund, is the Merrill Lynch High Yield Master II Index.  As a result
         of these two benchmarks, the performance of the portfolio manager for
         compensation purposes is measured against the criteria that are
         relevant to the portfolio manager's competitive universe.

o        Qualitative Performance. The qualitative performance component with
         respect to all of the accounts managed by the portfolio manager
         includes objectives, such as effectiveness in the areas of teamwork,
         leadership, communications and marketing, that are mutually established
         and evaluated by each portfolio manager and management.

o        Pioneer Results and Business Line Results. Pioneer's financial
         performance, as well as the investment performance of its investment
         management group, affect a portfolio manager's actual bonus by a
         leverage factor of plus or minus (+/-) a predetermined percentage.

The quantitative and qualitative performance components comprise 80% and 20%,
respectively, of the overall bonus calculation (on a pre-adjustment basis). A
portion of the annual bonus is deferred for a specified period and may be
invested in one or more Pioneer funds.

Certain portfolio managers may participate in other programs designed to reward
and retain key contributors. Senior executives or other key employees may be
granted performance units based on the stock price performance of UniCredito
Italiano and the financial performance of Pioneer Global Asset Management
S.p.A., which are affiliates of Pioneer. Portfolio managers also may participate
in a deferred compensation program, whereby deferred amounts are invested in one
or more Pioneer funds.


Share Ownership by Portfolio Manager. The following table indicates as of March
31, 2008 the value, within the indicated range, of shares beneficially owned by
the portfolio manager of the fund.

behalf of the registrant or any affiliated purchaser, as defined in

that is registered by the registrant pursuant to Section 12 of the
Exchange Act (15 U.S.C. 781). Instruction to paragraph (a). Disclose

through February 15, February 16 through March 15, March 16 through
April 15, April 16 through May 15, May 16 through June 15, and June 16
through July 15.

During the period covered by this report, there were no purchases
made by or on behalf of the registrant or any affiliated purchaser
as defined in Rule 10b-18(a)(3) under the Securities Exchange Act
of 1934 (the Exchange Act), of shares of the registrants equity
securities that are registered by the registrant pursuant to
Section 12 of the Exchange Act.


Item 10. Submission of Matters to a Vote of Security Holders.

Describe any material changes to the procedures by which shareholders
may recommend nominees to the registrants board of directors, where
those changes were implemented after the registrant last provided
disclosure in response to the requirements of Item 7(d)(2)(ii)(G)
of Schedule 14A (17 CFR 240.14a-101), or this Item.


There have been no material changes to the procedures by which the
shareholders may recommend nominees to the registrants board of
directors since the registrant last provided disclosure in response
to the requirements of Item 7(d)(2)(ii)(G) of Schedule 14(A) in
its definitive proxy statement, or this Item.


ITEM 11. CONTROLS AND PROCEDURES.

(a) Disclose the conclusions of the registrant's principal executive officer or
officers and principal financial officer or officers, or persons performing
similar functions, about the effectiveness of the registrant's disclosure
controls and procedures (as defined in Rule 30a-2(c) under the Act (17 CFR
270.30a-2(c))) based on their evaluation of these controls and procedures as of
a date within 90 days of the filing date of the report that includes the
disclosure required by this paragraph.

The registrant's principal executive officer
and principal financial officer have
concluded that the registrant's disclosure
controls and procedures are effective based
on their evaluation of these controls and
procedures as of a date within 90 days of the
filing date of this report.


(b) Disclose whether or not there were significant changes in the registrant's
internal controls or in other factors that could significantly affect these
controls subsequent to the date of their evaluation, including any corrective
actions with regard to significant deficiencies and material weaknesses.

There were no significant changes in the
registrant's internal control over financial
reporting that occurred during the second
fiscal quarter of the period covered by this
report that have materially affected, or are
reasonably likely to materially affect, the
registrant's internal control over financial
reporting.

The registrant's principal executive officer and principal financial
officer, however, voluntarily are reporting the following information:

In August of 2006 the registrant's investment adviser
enhanced its internal procedures for reporting performance
information required to be included in prospectuses.
Those enhancements involved additional internal controls
over the appropriateness of performance data
generated for this purpose.  Such enhancements were made
following an internal review which identified
prospectuses relating to certain classes of shares of
a limited number of registrants where, inadvertently,
performance information not reflecting the deduction of
applicable sales charges was included. Those prospectuses
were revised, and the revised prospectuses were distributed to
shareholders.


ITEM 12. EXHIBITS.

File the exhibits listed below as part of this Form. Letter or number the
exhibits in the sequence indicated.

(a) Any code of ethics, or amendment thereto, that is the subject of the
disclosure required by Item 2, to the extent that the registrant intends to
satisfy the Item 2 requirements through filing of an exhibit.



(b) A separate certification for each principal executive officer and principal
financial officer of the registrant as required by Rule 30a-2 under the Act
(17 CFR 270.30a-2).

Filed herewith.
