LETTER TO SHAREOWNERS 3/31/04
- --------------------------------------------------------------------------------

Dear Shareowner,
- --------------------------------------------------------------------------------
Last year's stock market rally carried over into early 2004 but ran out of steam
as investors reassessed the dramatic rise in stock valuations. The
technology-rich NASDAQ Composite Index, having risen the fastest, was the first
to feel pressure; the Dow Jones Industrial Average and Standard & Poor's 500
soon gave up some gains as well. By the end of March, these major indicators
were little changed from year-end levels but well ahead of where they stood a
year ago.

In general terms, smaller companies outperformed large companies, and emerging
markets outpaced developed countries, as both benefited from weakness in the
U.S. dollar. Corporate bonds, here and overseas, recorded strong gains. U.S.
Treasury issues also performed well, as the Federal Reserve Board signaled that
it was in no hurry to raise interest rates, given the mixed economic data it was
seeing.

Those mixed economic reports were also responsible for the stock market's
sluggishness. While corporate profits expanded at a healthy rate, unemployment
remained high and consumer confidence dropped sharply in February. Increased
productivity, a company's ability to produce more goods or services for each
hour worked, was a major factor in the disappointing pace of job creation.
However, jobs data improved markedly in March when the government reported U.S.
employers had added over 300,000 jobs, the largest figure in years; at the same
time, January and February numbers were revised upward. Payroll expansion
reached into most sectors, while employment held steady in manufacturing after a
long period of declines. The markets reacted positively to the jobs report. We
believe that renewed hiring means companies are optimistic about the outlook for
profits in the months ahead. In fact, many businesses are building up
inventories in expectation of increased product demand.

The key drivers of the expansion, low interest rates and reduced federal income
taxes, remain in place. Consequently, we think the U.S. economy retains
impressive growth potential through the rest of this year. An expanding economy
could have implications for the way your portfolio is balanced, so an
appointment with your professional financial advisor may well be in order.

Respectfully,

/s/ OSBERT M. HOOD

Osbert M. Hood, President and Chief Executive Officer

PORTFOLIO MANAGEMENT DISCUSSION 3/31/04
- --------------------------------------------------------------------------------

High-yield bonds posted strong returns during the 12 months ended March 31,
2004, as evidence grew of a quickening economic expansion globally, as well as
in the United States. At the same time, the Federal Reserve kept short-term
interest rates at 40-year lows, creating opportunities for leveraged investment
strategies to borrow funds inexpensively and then invest in appreciating assets.
The following is an interview with Kenneth J. Taubes, who discusses the
performance of High Income Trust during the period. Mr. Taubes, director of
Pioneer's Fixed Income Group, oversees the team responsible for the daily
management of the Trust.

Q: How did the Trust perform, Ken?

A: The Trust performed exceptionally well. For the 12 months ended March 31,
   2004, Pioneer High Income Trust had a total return of 34.31% at net asset
   value and 27.33% at market price, with a premium of market price-to-net asset
   value of 2.3% on March 31, 2004. The benchmark Merrill Lynch High Yield
   Master II Index returned 22.21% during the same 12 months. The Trust also
   delivered healthy income. On March 31, the current 30-day SEC yield was
   11.67%.

Q: What were the factors that influenced performance?

A: We had an excellent backdrop for high-yield bonds. The U.S. Federal Reserve
   Board kept short-term interest rates low, which helped the portfolio in two
   ways.

   First, the liquidity in the economy helped stimulate growth, which benefited
   corporations issuing high-yield bonds. Gross domestic product rose and
   corporate profits increased, while overall corporate credit improved in
   quality and default rates dropped. In addition, growth in the global economy
   started accelerating, helping many companies, both directly and indirectly.
   Domestic high-yield bonds were one of the better performing asset classes
   over the 12 months, and they substantially outperformed high-grade fixed-
   income securities, including Treasuries.

   Second, the low rates enabled the Trust to borrow funds inexpensively and
   invest in additional high-yield bonds, using the leverage to invest in
   higher-yielding bonds, which generated additional income to the Trust. At the
   end of the fiscal period, on March 31,

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

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

   2004, about 26% of the Trust was leveraged, giving a powerful stimulant to
   performance as high-yield bonds gained in value.

   In managing the Trust, we overweighted (relative to the Trust's benchmark)
   the securities of cyclical companies and industrial corporations, which stood
   to benefit from the expanding economy. At the same time, we deemphasized the
   more defensive utilities sector. We also maintained an exposure to
   international and emerging-market high-yield debt. At the end of the fiscal
   year, more than 20% of assets were invested in foreign bonds.

Q: What were some of the investments that most affected performance?

A: Several European holdings performed particularly well, as the bonds
   appreciated in the local currencies and the currencies gained in value
   against the U.S. dollar. One of the leading performers was Aker Kvaerner, a
   Norwegian engineering, construction and ship-building company. The bonds rose
   in value as the company restructured its business and started to benefit from
   the pickup in the global economy. At the same time, the Norwegian kroner rose
   in value against the dollar. Other European companies that added to returns
   included Huntsman International, a chemical company, and Crown Cork, a
   packaging company.

   Among the Trust's emerging markets investments, the bonds of Brazilian brewer
   Ambev, a long-time holding, rose in value when the company was taken over by
   the Dutch firm Interbrew.

   One of the best performing investments was Continental Airlines. The airline
   industry had been out of favor, but we believed Continental had successfully
   attacked its cost structure and was poised to benefit from the cyclical
   upturn. The bonds posted striking price gains after we invested in the summer
   of 2003. We subsequently sold our position, and then reinvested in
   Continental because we think it is the most sound among high-yield issuers in
   the airline industry.

   We invested in the bonds of Fonda Group, a packaging company, when they were
   at distressed prices. The bonds then started gaining as the company improved
   its operations and started to benefit from the economic rebound. Finally,
   Fonda Group was acquired by


                                                                               5

   its largest competitor, and the bond's prices rose above face value before
   they were called away.

   Another excellent performer was Alamosa Holdings, an affiliate of the Sprint
   wireless network, which has restructured its debt and is poised to benefit
   from the improving prospects in the wireless phone business.

   While most portfolio investments did well, we did have some disappointments.
   Evergreen Aviation, an international freight carrier with a big government
   business, fell after the United States allowed only government planes to fly
   cargo into Iraq. The policy meant that Evergreen lost much of its lucrative
   freight business to Kuwait and Saudi Arabia. We have sold the portfolio's
   position in Evergreen Aviation. The bonds of Constar, a packaging company
   specializing in the manufacture of plastic soft-drink bottles, also
   underperformed, as increasing competition in the industry weakened the
   company's ability to set prices. We have reduced our position in Constar.

Q: What is your outlook for high-yield investments?

A: We think the investment backdrop should continue to be favorable for
   high-yield bonds, which should benefit from the strong U.S. economy and the
   expanding global economy. We believe the Federal Reserve is likely to keep
   short-term interest rates low in the short run in an effort to provide
   further stimulation to the economy, even if the board begins raising rates
   later this year. Corporate revenues are increasing, and productivity has been
   improving, resulting in healthy profit gains for many companies. We expect
   that default rates by high-yield issuers should continue to decline.

   After the strong performance by high-yield bonds since 2000, however, it
   probably is not realistic to expect significant price gains in the near
   future. The possibility exists for high-yield bonds to produce total returns
   consistent with their stated interest (coupon) rates.

The Trust's investment objective is a high level of current income. The Trust
may, as a secondary objective, also seek capital appreciation to the extent
consistent with its investment objective. There can be no assurance that the
Trust will achieve its investment objectives. Under normal market conditions,
the Trust invests at least 80% of its assets (net assets plus borrowing for
investment purposes) in below investment grade (high yield) debt securities,
loans and preferred stocks. Because the Trust's investments will be concentrated
in high yield securities, it will be subject to risks of such securities. Below
investment grade securities are commonly referred to as "junk bonds" and are
considered speculative with respect to the issuer's capacity to pay interest and
repay principal. They involve greater risk of loss, are subject to greater price
volatility and are less liquid, especially during periods of economic
uncertainty or change, than higher rated debt securities. Risks of the investing
in the Trust are discussed in greater detail in the Trust's registrations
statement on Form N-2 relating to its common shares, which was filed with the
Securities and Exchange Commission on April 29, 2002.

The Trust's total return at net asset value for the fiscal year ended March 31,
2004, after net expenses and dividends to the preferred shareowners, was 34.31%.
The Trust's total return for the fiscal year ended March 31, 2004 based on
changes in market price was 27.33%.

NOTES TO FINANCIAL STATEMENTS 3/31/04

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 25, 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, and the sale and issuance to
Pioneer Investment Management, Inc. (PIM), the Trust's investment adviser, a
wholly owned indirect subsidiary of UniCredito Italiano S.p.A. (UniCredito
Italiano), of 6,981 shares of beneficial interest at an aggregate purchase price
of $100,003. PIM has reimbursed the amount by which the aggregate of all the
Trust's organizational expenses and offering costs (other than the sales load)
exceeded $0.03 per share of the common share offering. 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 invests in below investment grade (high yield) debt securities and
preferred stocks. These high yield securities may be convertible into equity
securities of the issuer. Debt securities rated below investment grade are
commonly referred to as "junk bonds" and are considered speculative. These
securities involve greater risk of loss, are subject to greater price
volatility, and are less liquid, especially during periods of economic
uncertainty or change, than higher rated debt securities.

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


                                                                              23

NOTES TO FINANCIAL STATEMENTS 3/31/04                              (continued)
- --------------------------------------------------------------------------------

A. Security Valuation

   Security transactions are recorded as of trade date. Securities are valued at
   the last sales price on the principal exchanges where they are traded. 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 dealers and other sources, as
   required. Securities for which market quotations are not readily available
   are valued at their fair values as determined by, or under the direction of,
   the Board of Trustees. Trading in foreign securities is substantially
   completed each day at various times prior to the close of the New York Stock
   Exchange. 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, 2004 the Trust had no fair valued securities.
   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. Discount and premium on fixed income
   securities are accreted and amortized daily, respectively, 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 underlying monthly paydowns. Interest income,
   including income on interest bearing cash accounts, is recorded on an accrual
   basis. Temporary cash investments are valued at amortized cost.

   The Trust's investments in 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.

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

Pioneer High Income Trust

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

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

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 price 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 contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 4).

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.

   The amount and characterization of distributions to shareowners for financial
   reporting purposes is determined in accordance with


                                                                              25

NOTES TO FINANCIAL STATEMENTS 3/31/04                              (continued)
- --------------------------------------------------------------------------------

   federal income tax rules. Therefore, the source 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 on investment and
   foreign currency transactions, or from paid-in capital, depending on the type
   of book/tax differences that may exist.

   At March 31, 2004, the Trust reclassified $357,417 to decrease accumulated
   net realized loss on investments and foreign currency transactions and to
   increase distributions in excess of net investment income. 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 year ended March 31, 2004 and the period ended March 31, 2003 was
   as follows:

- --------------------------------------------------------------------------------
                                       2004             2003
  Distributions paid from:
  Ordinary Income                 $45,653,275      $37,808,117
  Net long-term capital gains               -                -
                                  -----------      -----------
  Total taxable distribution      $45,653,275      $37,808,117
                                  ===========      ===========
- --------------------------------------------------------------------------------

   The following shows components of distributable earnings on a federal income
   tax basis at March 31, 2004.

- --------------------------------------------------------------------------------
  Undistributed ordinary income      $ 2,324,461
  Capital loss carryforward             (704,168)
  Unrealized appreciation             53,172,715
                                     -----------
  Total                              $54,793,008
                                     ===========
- --------------------------------------------------------------------------------

   The difference between book/basis and tax-basis unrealized appreciation is
   primarily attributable to the tax deferral of losses on wash sales, the
   realization for tax purposes of unrealized gains on certain foreign currency
   contracts, differences in the accrual of income on securities in default and
   the difference between book and tax amortization methods for premiums and
   discounts on fixed income securities.

E. Repurchase Agreements

   With respect to repurchase agreements entered into by the Trust, the value of
   the underlying securities (collateral), including accrued interest received
   from counterparties, is required to be at least equal to or in excess of the
   repurchase agreement 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. PIM 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 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
   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 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 managed 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 by notifying Mellon Investor Services LLC, the agent for
   shareowners in administering the Plan (the "Plan Agent"), prior to any
   dividend


                                                                              27


Pioneer High Income Trust

NOTES TO FINANCIAL STATEMENTS 3/31/04                              (continued)
- --------------------------------------------------------------------------------

   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 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

PIM manages the Trust's portfolio. Management fees are calculated weekly at the
annual rate of 0.60% of the Trust's average weekly managed assets. "Managed
assets" is the average weekly 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.

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

In addition, under PIM's management and administration agreements, certain
other services and costs are paid by the Trust. PIM has retained Princeton
Administrators, L.P., an affiliate of Merrill Lynch, Pierce, Fenner & Smith
Incorporated, to provide certain administrative services to the Trust on its
behalf. PIM pays Princeton Administrators, L.P., a monthly fee at an annual
rate of 0.08% of the average weekly value of the Trust's managed assets,
subject to a minimum monthly fee of $10,000. Princeton Administrators, L.P.
receives no compensation directly from the Trust.

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 Mellon Investor Services LLC, provides substantially all
transfer agent and shareowner services related to the Trust's common shares at
negotiated rates. Deutsche Bank Trust Company Americas is the transfer agent,
registrar, dividend paying agent and redemption agent with respect to the
Trust's Auction Market Preferred Shares (AMPS). The Trust pays Deutsche Bank
Trust Company Americas an annual fee, as is agreed to from time to time by the
Trust and Deutsche Bank Trust Company Americas, for providing such services.

4. Forward Foreign Currency Contracts
During the year ended March 31, 2004, the Trust had entered 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 foreign currency.
Alternatively, prior to the settlement date of the portfolio hedge, the Trust
may close out such contracts by entering into an offsetting hedge contract

Open portfolio hedges at March 31, 2004 were as follows:

- --------------------------------------------------------------------------------
                Net                                                   Net

The Trust's gross outstanding forward currency settlement contracts receivable
and payable were $704,818 and $700,000, respectively, resulting in a net
receivable of $4,818.


                                                                              29

For the year ended March 31, 2004 and the period ended March 31, 2003, the Trust
charged $0 and $741,715, respectively, in offering costs incurred in connection
with the Trust's offering of common shares to paid-in capital.

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, 2004, there were 6,040 AMPS ("preferred shares") as follows: Series
M7-2,020, Series W28-2,020 and Series TH7-2,000. On August 1, 2003, the Trust
reclassified and issued 2,000 shares of common shares into Series TH. For the
year ended March 31, 2004 and the period ended March 31, 2003, estimated
offering costs of $166,972 and $232,212, respectively and underwriting discounts
of $500,000 and $1,010,000, respectively, have been charged to paid-in capital.

Dividends on Series M7 AMPS and Series TH7 AMPS are cumulative at a rate which
is reset every seven days based on the results of an auction. Dividends on
Series W28 AMPS are also cumulative at a rate reset every 28 days based on the
results of an auction. Dividend rates ranged from 1.00% to 1.48% during the year
ended March 31, 2004.

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 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.

payable April 30, 2004, to shareowners of record on April 15, 2004.

For the period April 1, 2004 to April 30, 2004, dividends declared on preferred
shares totaled $125,672 in aggregate for the three outstanding preferred share
series.

Report of Independent Auditors
- --------------------------------------------------------------------------------

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

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Pioneer High Income Trust (the "Trust") as of
March 31, 2004, and the related statement of operations for the year then ended,
and the statements of changes in net assets and the financial highlights for
each of the periods indicated in the two years 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 auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of March 31, 2004, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer High Income Trust at March 31, 2004, the result of its operations for
the year then ended, and the changes in its net assets and the financial
highlights for each of the periods indicated in the two years then ended, in
conformity with accounting principles generally accepted in the United States.

                                                           /s/ ERNST & YOUNG LLP

 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 recognizes 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 recognizes 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.

    N/A

(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 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.

Aggregate Non-Audit Fees

The aggregate non-audit fees for the Trust and affiliates, as
previously defined, totaled approximately $25,100 in 2004 and approximately
$42,300 in 2003. These fees include services provided prior to May 6, 2003,
the effective date of the pre-approval process.

(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

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.

                                    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.

                             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 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:

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

            -     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);

            -     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

            -     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.

      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 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:

            -     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);

            -     Retains a record of the vote cast;

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

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

      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:

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

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

                  -     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.

      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.

                              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:

            -     Corporate name change.

            -     A change of corporate headquarters.

            -     Stock exchange listing.

            -     Establishment of time and place of annual meeting.

            -     Adjournment or postponement of annual meeting.

            -     Acceptance/approval of financial statements.

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

            -     Approval of minutes and other formalities.

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

            -     Amendments to authorized signatories.

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

            -     Acceptance of labor agreements.

            -     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:

            -     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.

            -     Restore shareholder rights to ratify the auditors.

      We will normally oppose proposals that require companies to:

            -     Seek bids from other auditors.

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

            -     Indemnify auditors.

            -     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.

GENERAL BOARD ISSUES

      Pioneer will vote for:

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

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

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

            -     Election of an honorary director.

      We will vote against:

            -     Minimum stock ownership by directors.

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

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

            -     Requirements to provide two candidates for each board seat.

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

            -     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:

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

            -     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:

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

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

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

            -     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).

            -     Contested election of directors.

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

            -     Mandatory retirement policies.

            -     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:

            -     Cumulative voting.

            -     Increase ability for shareholders to call special meetings.

            -     Increase ability for shareholders to act by written consent.

            -     Restrictions on the ability to make greenmail payments.

            -     Submitting rights plans to shareholder vote.

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

            -     Opting out of the following state takeover statutes:

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

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

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

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

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

      -     Fair price provisions.

      -     Authorization of shareholder rights plans.

      -     Labor protection provisions.

      -     Mandatory classified boards.

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

            -     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.

            -     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.

            -     Proposals that allow shareholders to nominate directors.

      We will vote against:

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

            -     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.

            -     Classes of shares with unequal voting rights.

            -     Supermajority vote requirements.

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

            -     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.

            -     Extension of advance notice requirements for shareholder
                  proposals.

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

            -     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.

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:

            -     Changes in par value.

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

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

            -     Bond issuance.

            -     Increases in "ordinary" preferred stock.

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

            -     Cancellation of company treasury shares.

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

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

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

      -     Number of shares currently available for issuance;

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

      -     Proposed use of the additional shares; and

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

            -     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.

            -     Proposals to submit private placements to shareholder vote.

            -     Other financing plans.

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

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:

            -     401(k) benefit plans.

            -     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.

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

      -     Amendments to performance plans to conform with OBRA;

      -     Caps on annual grants or amendments of administrative features;

      -     Adding performance goals; and

      -     Cash or cash-and-stock bonus plans.

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

            -     Require that option repricings be submitted to shareholders.

            -     Require the expensing of stock-option awards.

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

            -     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%.

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

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

      -     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.

      -     The plan must not:

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

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

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

            -     All other employee stock purchase plans.

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

            -     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.

      We will vote against:

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

            -     Elimination of stock option plans.

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

            -     Limits on executive and director pay.

            -     Stock in lieu of cash compensation for directors.

CORPORATE GOVERNANCE

      Pioneer will vote for:

            -     Confidential Voting.

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

            -     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:

            -     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.

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

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

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

      We will vote against:

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

            -     Limitations on stock ownership or voting rights.

            -     Reduction in share ownership disclosure guidelines.

MERGERS AND RESTRUCTURINGS

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

            -     Mergers and acquisitions.

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

            -     Debt restructurings.

            -     Conversion of securities.

            -     Issuance of shares to facilitate a merger.

            -     Private placements, warrants, convertible debentures.

            -     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:

            -     Establishment of new classes or series of shares.

            -     Establishment of a master-feeder structure.

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

            -     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.

            -     Approval of new or amended advisory contracts.

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

            -     Authorization for, or increase in, preferred shares.

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

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

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:

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

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

            -     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.
