Dear Shareowner,
--------------------------------------------------------------------------------
Staying diversified and keeping your portfolio invested in the markets are two
general investment principles that have served investors well over time. These
were particularly useful guides during the past year, as U.S. and global stock
and bond markets grew strongly during this period.

The markets were supported by relatively low short-term interest rates and
generally strong economies around the globe. The U.S. stock market, as measured
by the Standard & Poor's 500 Index, gained approximately 10% over the 12 months
ending March 31, 2007. European and emerging markets equities performed even
better, with indexes in those regions rising more than 20% over the same period.
The U.S. bond market, despite growing concerns about the health of the U.S.
mortgage industry, gained roughly 7% over the past 12 months, as measured by the
Lehman Aggregate Bond Index. The high yield market, as measured by the Merrill
Lynch High Yield Bond Master II Index, returned nearly 12%.

We believe that the climate for investors generally will continue to be
positive. While still strong, the U.S. economy has slowed. This was due in part
to the lagging effects of rising energy and commodity prices, rising short-term
interest rates from historically low levels, and the effect of U.S. factories
approaching full utilization.

We have enjoyed a cyclical recovery with strong economic growth, and the U.S.
economy now appears to be slowing to a rate that may be more sustainable. The
Federal Reserve Board has indicated a reduced likelihood of future rate hikes,
and continues to highlight its commitment to keeping inflationary pressures
contained. This is in keeping with "best practices" among the world's central
banks: low and stable inflation is believed to be the best backdrop for stable
economic growth and low average unemployment.

In Europe, healthy labor markets are supporting growing consumption and rising
GDP growth. Inflationary pressures appear to be largely under control, helped by
productivity gains and a positive operating environment for European companies
that are finding strong export markets for their goods and services around the
globe. Japanese economic growth continues to make progress, and the country has

become a more attractive market compared to recent years. China continues its
rise as a world economic power, and its stock market has experienced the wide
market swings that often accompany rapid growth.

While the outlook generally appears favorable for investors, sudden swings in
the markets should be expected. Just as staying diversified and staying invested
are important investment principles, it is also important to pay attention to
asset allocation. As always, we encourage shareowners to work closely with their
financial advisor to find the appropriate mix of investments in stocks, bonds
and money market assets so that it is aligned to your particular risk tolerance
and investment objective.

Respectfully,

/s/ Daniel K. Kingsbury

Pioneer Municipal High Income Advantage Trust

--------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT DISCUSSION 3/31/07
--------------------------------------------------------------------------------

Throughout the Trust's fiscal year, investors in Pioneer Municipal High Income
Advantage Trust benefited from a well-diversified portfolio of securities that
provided a relatively high level of tax-free income. In the following interview,
David Eurkus, who is responsible for daily management of the Trust, discusses
some of the factors that had an impact on the municipal bond market and the
Trust.

Q:   How did the Trust perform over the past 12 months?

A:   For the 12-month period ended March 31, 2007, Pioneer Municipal High Income
     Advantage Trust produced a total return of 11.96% at net asset value and
     10.21% at market price. As of March 31, 2007, the Trust was selling at a
     discount of market price to net asset value of 1.9%. The Lehman Brothers
     Municipal Bond Index returned 5.43%, while the Lehman Brothers
     Non-Investment Grade Municipal Bond Index returned 9.84% for the same
     period. At the end of the 12 months, the Trust held 144 issues in 35
     states, territories and the District of Columbia. On March 31, 2007, the
     Trust's 30-day SEC yield was 7.52%. When reviewing the Trust's relative
     performance, it is important to note that the Lehman Brothers Municipal
     Bond Index tracks the performance only of investment-grade bonds and does
     not include below investment-grade bonds, which are a significant part of
     the portfolio. At the end of the 12 months, about 45% of the Trust's total
     investments were in investment-grade bonds with the remaining in below
     investment-grade bonds.

     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 costs.

Q:   What was the investment environment like during the year?

A:   The investment backdrop changed substantially during the fiscal year. At
     the beginning of the period, interest rates were on an upward trajectory in
     the face of relatively strong economic growth. As a result, the Federal
     Reserve continued to boost the Federal funds rate, the rate banks charge
     for overnight loans. In the second half of the period, economic growth
     moderated; and

Pioneer Municipal High Income Advantage Trust

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

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

     for several months the central bank left the Federal funds rate unchanged
     at 5.25%, and market rates declined. Throughout the 12 months, investors
     gravitated toward the riskiest investments, boosting the prices of
     lower-quality, higher-yielding bonds. For the entire fiscal period, these
     lower-quality assets led the fixed-income market.

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

A:   In keeping with our buy-and-hold strategy, we made relatively few changes
     to the Trust, maintaining a mix of 31.3% of total investments in
     investment-grade bonds, 68.1% of total investments in below
     investment-grade bonds, and 0.6% of total investments in cash equivalents.
     At the end of the fiscal period, the Trust's average quality was BBB-. We
     kept the Trust invested in sectors that comprise the economic fabric of the
     United States, including transportation, education, healthcare, and public
     power, among others. In addition, we had a position in tobacco bonds, which
     are backed by tobacco companies' payments to states. We also created a
     position in bonds issued by correctional institutions that have been
     privatized by the federal government and are now being built and managed by
     private corporations.

     On March 31, 2007, 29% of the Trust was leveraged, which means that in the
     past we borrowed funds at relatively low rates and invested those funds in
     high-yielding bonds. This leveraging strategy has aided return for several
     years. Should rates decline, the cost of borrowing would also go down,
     providing the Trust with a modest amount of additional income. A rise in
     short-term interest rates in the future would add to the Trust's borrowing
     costs, and the ability to sustain present dividend levels could be
     affected.

Q:   What contributed to performance?

A:   Nearly all of the portfolio's positions contributed to results, but the
     biggest gains came from transportation and education bonds. In addition,
     the Trust's higher-yielding, below investment-grade bonds outperformed the
     investment-grade bonds in the portfolio.


                                                                               5

PORTFOLIO MANAGEMENT DISCUSSION 3/31/07                            (continued)
--------------------------------------------------------------------------------

Q:   What detracted from performance?

A:   Our holdings in the housing sector, which accounted for 2.1% of total
     investments, underperformed because of weakness in the real estate industry
     in general and concerns about the rise in sub-prime mortgage defaults in
     particular. Because of the relatively strong economy, many issuers have a
     surplus of cash which they are using to pay down their bond debt earlier
     than expected. As some of our bonds have been called, or redeemed, before
     their maturity dates, we have invested the proceeds in new securities that
     have lower yields than the redeemed bonds. Having bonds called sooner than
     expected is a normal part of the fixed-income process, and we continue to
     find attractive investment opportunities.

Q:   What is your outlook over the next six months?

A:   The environment continues to be attractive for municipal bonds, as economic
     growth moderates and interest rates and inflation remain at relatively low
     levels. While new bond issuance has declined, demand for high-yield
     securities remains robust as new types of investors, such as hedge funds
     and property and casualty insurers, seek the tax-advantaged yields that
     municipal bonds can provide. This supply/demand dynamic is positive for the
     Trust because it has the potential of increasing the value of the bonds in
     the portfolio. As we look ahead, we plan to maintain our investment
     approach of keeping the Trust fully invested in sectors that are vital to
     the U.S. economy.

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.

A portion of income may be subject to state, federal, and/or alternative minimum
tax. Capital gains, if any, are subject to a capital gains tax. 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. By concentrating in municipal
securities, the portfolio is more susceptible to adverse economic, political or
regulatory developments than is a portfolio that invests more broadly.
Investments in the Trust are subject to possible loss due to the


6

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

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

financial failure of underlying securities and their inability to meet their
debt obligations.

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 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 October 31, 2003. The Lehman Brothers Municipal Bond
Index is a broad measure of the municipal bond market. Lehman Brothers
Non-Investment Grade Municipal Bond Index totals over $26 billion in market
value and maintains over 1300 securities. Municipal bonds in this index have the
following requirements: maturities of one year or greater, sub investment grade
(below Baa or non-rated), fixed coupon rate, issue date later than 12/31/90,
deal size over $20 million, maturity size of at least $3 million. 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 Indices.

NOTES TO FINANCIAL STATEMENTS 3/31/07
--------------------------------------------------------------------------------

1.   Organization and Significant Accounting Policies

Pioneer Municipal High Income Advantage Trust (the "Trust") was organized as a
Delaware statutory trust on August 6, 2003. Prior to commencing operations on
October 20, 2003, 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 Trust may invest in both investment and below investment grade (high-yield)
municipal securities with a broad range of maturities and credit ratings. 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.

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 and sectors.

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

A.   Security Valuation

     Security transactions are recorded as of trade date. Securities are valued
     at prices supplied by independent pricing services, which consider such
     factors as Treasury spreads, yields, maturities


                                                                              27


Pioneer Municipal High Income Advantage Trust

NOTES TO FINANCIAL STATEMENTS 3/31/07                              (continued)
--------------------------------------------------------------------------------

     and ratings. Valuations may be supplemented by dealers and other sources,
     as required. The values of interest rate swaps are determined by obtaining
     dealer quotations. 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. At March 31, 2007, there were no
     securities fair valued. Temporary cash investments are valued at net asset
     value.

     Discount and premium on debt securities are accreted or amortized,
     respectively, daily on an effective yield to maturity basis and are
     included in interest income. Interest income, including 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.   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 amounts and characterizations of distributions to shareowners for
     financial reporting purposes are determined in accordance with 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 investments transactions,
     or from paid-in capital, depending on the type of book/tax differences that
     may exist.

     At March 31, 2007, the Trust reclassified $618,795 to increase
     undistributed net investment income and to increase accumulated 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.

     At March 31, 2007, the Trust had a capital loss carryforward of $14,156,085
     which will expire in 2014, if not utilized.

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


     The difference between book basis and tax basis unrealized appreciation is
     primarily attributable to the difference between book and tax amortization
     methods for premiums and discounts on fixed income securities, the accrual
     of income on securities in default and the difference between book and tax
     accounting for swap agreements.

C.   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

                                                                              29


Pioneer Municipal High Income Advantage Trust

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/07                              (continued)
--------------------------------------------------------------------------------

     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 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 daily
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


30


Pioneer Municipal High Income Advantage Trust

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

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

to leverage, short-term debt and the aggregate liquidation preference of any
outstanding preferred shares. Also, PIM has agreed for the first three years of
the Trust's investment operations to limit the Trust's total annual expenses
excluding offering costs for common and preferred shares, interest expense, the
cost of defending or prosecuting any claim or litigation to which the Trust is a
party (together with any amount in judgment or settlement), indemnification
expense or taxes incurred due to the failure of the Trust to qualify as a
regulated investment company under the Code or any other non-recurring or
non-operating expenses to 0.80% of the Trusts average daily managed assets. The
dividend on any preferred shares is not an expense for this purpose. For the
year ended March 31, 2007, the expense reduction under such arrangements was
$47,982. For the year ended March 31, 2007, the net management fee was
equivalent to 0.59% of the Trust's average daily managed assets, which was
equivalent to 0.84% 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,
2007, $269,435 was payable to PIM related to management costs, administrative
costs and certain other services and is included in "Due to affiliate" on the
Statement of Assets and Liabilities.

The Trust has retained Princeton Administrators, LLC ("Princeton") to provide
certain administrative services to the Trust on its behalf. The Trust pays
Princeton a monthly fee at an annual rate of 0.07% of the average daily value of
the Trust's managed assets, subject to a minimum monthly fee of $10,000.

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 redemption agent with
respect to the Trust's Auction Preferred Shares ("APS"). The Trust pays Deutsche
Bank an annual fee,


                                                                              31


Pioneer Municipal High Income Advantage Trust

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/07                              (continued)
--------------------------------------------------------------------------------

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, 2007, the Trust's
expenses were reduced by $63 under such arrangement.

5.   Interest Rate Swaps

The Trust may enter into interest rate swap transactions to attempt to protect
itself from increasing dividend or interest expense on its leverage resulting
from increasing short-term interest rates. The cost of leverage may rise with an
increase in interest rates, generally having the effect of lower yields and
potentially lower dividends to common shareowners. Interest rate swaps can be
used to "lock in" the cost of leverage and reduce the negative impact that
rising short-term interest rates would have on the Trust's leveraging costs.

An interest rate swap is an agreement between two parties, which involves
exchanging floating rate and fixed rate interest payments for a specified period
of time. Interest rate swaps involve the accrual of the net interest payments
between the parties on a daily basis, with the net amount recorded within the
unrealized appreciation/ depreciation of interest rate swaps on the Statement of
Assets and Liabilities. Once the interim payments are settled in cash, at the
pre-determined dates specified in the agreement, the net amount is recorded as
realized gain or loss from interest rate swaps on the Statement of Operations.
During the term of the swap, changes in the value of the swap are recognized as
unrealized gains and losses by "marking-to market" the market value of the swap
based on values obtained from dealer quotations. When the swap is terminated,
the Trust will record a realized gain or loss equal to the difference, if any,
between the proceeds from (or cost of) closing the contract and the cost basis
of the contract. The Trust is exposed to credit risk in the event of
non-performance by the other party to the interest rate swap. However, at March
31, 2007 the Trust does not anticipate non-performance by any counterparty. Risk
may also arise with regard to market movements in the value of the swap
arrangement that do not


32


Pioneer Municipal High Income Advantage Trust

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

exactly offset the changes in the related dividend requirement or interest
expense on the Trust's leverage.

Under the terms of the agreement entered into by the Trust, the Trust receives a
floating rate of interest and pays a fixed rate of interest for the term.
Details of the swap agreement outstanding as of March 31, 2007 were as follows:

6.   Trust Shares

There are an unlimited number of common shares of beneficial interest
authorized. Of the 22,740,627 common shares of beneficial interest outstanding
at March 31, 2007, PIM owned 6,981 shares.

Transactions in common shares of beneficial interest for the years ended March
31, 2007 and March 31, 2006 were as follows:

                                            ==========      ==========
--------------------------------------------------------------------------------


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, 2007, there were 6,000 APS as follows: Series A - 3,000 and Series
B - 3,000.

Dividends on Series A and Series B are cumulative at a rate, which is reset
every seven days based on the results of an auction. Dividend rates ranged from
2.94% to 4.05% during the year ended March 31, 2007.

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%.

                                                                              33

--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS 3/31/07                              (continued)
--------------------------------------------------------------------------------

The APS 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 APS 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 APS 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 APS 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

On July 13, 2006, the Financial Accounting Standards Board ("FASB") released
FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN
48"). FIN 48 provides guidance for how uncertain tax positions should be
recognized, measured, presented and disclosed in the financial statements. FIN
48 requires the evaluation of tax positions taken or expected to be taken in the
course of preparing the Trust's tax returns to determine whether the tax
positions have a "more-likely-than-not" probability of being sustained by the
applicable tax authority. Tax positions deemed to not meet the
more-likely-than-not threshold would be recorded as a tax benefit or expense in
the reporting period in which they are realized. Adoption of FIN 48 is required
for fiscal years beginning after December 15, 2006 and is to be applied to all
open tax years as of no later than September 28, 2007. At this time, management
is evaluating the implications of FIN 48 and any impact in the financial
statements has not yet been determined.

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

In addition, 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. At this time, management is currently evaluating the
implications of SFAS 157 and its impact on the Trust's financial statement
disclosures, if any, has not been determined.

8.   Subsequent Events

Subsequent to March 31, 2007, the Board of Trustees of the Trust declared a
dividend from undistributed net investment income of $0.07 per common share
payable April 30, 2007, to shareowners of record on April 16, 2007.

Subsequent to March 31, 2007, dividends declared and paid on preferred shares
totaled $485,460 in aggregate for the two outstanding preferred share series
through May 8, 2007.

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

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

We have audited the accompanying statement of assets and liabilities of Pioneer
Municipal High Income Advantage Trust (the "Trust"), including the schedule of
investments, as of March 31, 2007, 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
periods indicated therein. 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, 2007, by correspondence with the custodian. 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 Municipal High Income Advantage Trust at March 31, 2007, 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 periods indicated therein, in conformity with U.S. generally accepted
accounting principles.

FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN
APPROVING THE MANAGEMENT CONTRACT
--------------------------------------------------------------------------------

The Investment Company Act of 1940 requires that both the Board of Trustees and
a majority of the Independent Trustees (collectively "the Trustees"), voting
separately, annually approve the Trust's management contract (the "Management
Contract"). The Trustees have determined that the terms of the Management
Contract are fair and reasonable and that renewal of the contract: (i) will
enable the Trust to receive quality investment advisory services at a fee deemed
reasonable; and (ii) is in the best interests of the Trust and its shareowners.
In making such determinations, the Independent Trustees relied upon the
assistance of counsel to the Independent Trustees and counsel to the Trust.

Throughout the year, the Independent Trustees regularly met in executive
session, separately from the Interested Trustees of the Trust and any officer of
Pioneer Investment Management, Inc., the Trust's adviser (the "Investment
Adviser"), or its affiliates. While the Trustees, including the Interested
Trustees, act on all major matters relating to the Trust, a significant portion
of the activities of the Board of Trustees (including certain of those described
herein) is conducted through committees, the members of which are comprised
exclusively of Independent Trustees. Such committee meetings are attended by
officers of the Trust and/or officers of the Investment Adviser to the extent
requested by the members of the committee.

In evaluating the Management Contract, the Trustees conducted a review that was
specifically focused upon the renewal of the Management Contract, and also
relied upon their knowledge, resulting from their meetings throughout the year,
of the Investment Adviser, its services and the Trust. Both in meetings
specifically dedicated to renewal of the Management Contract and at other
meetings during the course of the year, the Trustees, including the Independent
Trustees, received materials relating to the Investment Adviser's investment and
management services under the Management Contract. These materials included
information on (i) the investment performance of the Trust, a peer group of
funds as classified by Morningstar, Inc., an independent evaluation service
("Morningstar") and two indices considered appropriate by the Independent
Trustees for this purpose, (ii) the general investment outlook in the markets in
which the Trust invests, (iii) the procedures employed to determine the value of
each of the Trust's assets, (iv) the Investment Adviser's management of the
relationships with the Trust's unaffiliated service providers, (v) the record of
compliance with the Trust's investment policies


                                                                              39

APPROVING THE MANAGEMENT CONTRACT                                  (continued)
--------------------------------------------------------------------------------

and restrictions and with the Trust's Code of Ethics and the structure and
responsibilities of the Investment Adviser's compliance department and (vi) the
nature, cost and character of non-investment management services provided by the
Investment Adviser and its affiliates , (viii) analyses of the benefits and
costs of the use of leverage through the issuance of the Trust's preferred
shares and sensitivity analyses based on changes in interest rates and (ix) the
discount or premium of the market price of the Trust's common stock relative to
its net asset value and measures that are or could be taken to address any
discount.

Specifically in connection with the Independent Trustees' review of the
Management Contract, the Independent Trustees requested, and the Investment
Adviser provided, additional information in order to evaluate the quality of the
Investment Adviser's services and the reasonableness of the fee under the
Management Contract. Among other items, this information included data or
analyses of (1) investment performance for one year period for the Trust and a
peer group of funds selected on the basis of criteria considered appropriate by
the Independent Trustees for this purpose, (2) management and other fees
incurred by a peer group of funds selected on the basis of criteria considered
appropriate by the Independent Trustees for this purpose, (3) the advisory fees
of comparable portfolios of other clients of the Investment Adviser, (4) expense
ratios for the Trust and a peer group of funds selected on the basis of criteria
considered appropriate by the Independent Trustees for this purpose, (5) the
overall organization of the Investment Adviser, (6) the Investment Adviser's
financial results and condition, including its and certain of its affiliates'
profitability in providing services to the Trust, (7) administrative
reimbursements paid to the Investment Adviser or affiliates, (8) investment
management staffing, and (9) operating expenses paid by the funds to third
parties.

The following summarizes factors considered by the Trustees in connection with
reviewing the information described above and their renewal of the Trust's
Management Contract. The Trustees did not identify any single factor as
all-important or controlling, and the summary does not detail all the matters
that were considered.

A.   Ancillary Benefits to Shareowners. The Trustees considered the benefits to
     shareowners of investing in a closed-end fund that is part of an
     established group of open and closed-end funds. The

40


Pioneer Municipal High Income Advantage Trust

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


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

     Trustees also noted that the relationship of the market price relative to
     the Trust's net assets attributed to its common shares was at least
     comparable to other closed-end funds with similar investment approaches.

B.   Compliance and Investment Performance. The Trustees determined that the
     Investment Adviser had policies and systems reasonably designed to achieve
     compliance with the Trust's investment objective and regulatory
     requirements. The Trustees also reviewed the Trust's absolute investment
     performance based upon total return, as well as the Trust's performance
     relative to the performance of both a peer group considered appropriate by
     the Independent Trustees for this purpose and the Lehman Municipal Bond
     Index. The Trust's performance, based upon total return, was in the fourth
     quintile of its Morningstar category peer group for the 12 months ended
     June 30, 2006. (In all quintile rankings referred to throughout this
     discussion first quintile is most favorable to the Trust's shareowners.
     Thus, highest relative performance would be first quintile and lowest
     relative expenses also would be first quintile.) The Trustees also
     considered the yield of the Trust, before deduction of expenses, compared
     to the yield of the index. The Trustees concluded that the Trust
     underperformed relative to its peers during the short period since its
     inception.

C.   The Investment Adviser's Personnel and Methods. The Trustees reviewed the
     background of members of the team responsible for the daily management of
     the Trust and the Trust's investment objective and discipline. The
     Independent Trustees also have had discussions with senior management of
     the Investment Adviser responsible for investment operations and the senior
     management of the Investment Adviser's fixed income group. Among other
     things, the Trustees considered the size, education and experience of the
     Investment Adviser's investment staff and their use of technology and
     emphasis on analytics in view of the risk profile of securities in which
     the Trust invests. The Trustees concluded that the Investment Adviser had
     the quality and depth of personnel and the well-developed methods essential
     to perform its duties under the Management Contract.

D.   Nature and Quality of Other Services. The Trustees considered the nature,
     quality and extent of other services provided to shareowners of the Trust,
     including administrative and shareowner


                                                                              41

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

     services performed by the Investment Adviser under the Management Contract.
     The Trustees also considered the reasonableness of the arrangements for
     reimbursement of the Investment Adviser's out-of-pocket costs and expenses,
     including overhead, for certain administrative services that the Investment
     Adviser is not required to provide under the Management Contract. The
     Trustees also considered the nature and extent of the other services
     provided by the Investment Adviser or its affiliates under other contracts,
     as well as the Investment Adviser's supervision of third party service
     providers. Based on these considerations, the Trustees concluded that the
     nature, quality and extent of such services are satisfactory and reliable
     and serve the shareowners of the Trust well.

E.   Management Fee and Expenses. The Trustees considered the Investment
     Adviser's fee under the Management Contract relative to the management fees
     charged by its Morningstar category peer group. The Trust's management fee
     for the 12 months ended June 30, 2006 was in the third quintile relative to
     the management fees paid by the other funds in that peer group for the
     comparable period. The Trustees also considered the Trust's expense ratio
     for the 12 months ended June 30, 2006 and expense ratios for the comparable
     period of the peer group of funds selected on the basis of criteria
     considered appropriate by the Independent Trustees for this purpose using
     data provided by Strategic Insight Mutual Fund Research and Consulting,
     LLC, an independent third party. The Trustees found the Trust's expense
     ratio for the 12 months ended June 30, 2006 (after giving effect to the
     expense limitation) to be in the third quintile, according to data for the
     applicable peer group for the most recent fiscal year.

F.   Profitability. The Trustees considered the level of the Investment
     Adviser's profits with respect to the management of the Pioneer funds,
     including a review of the Investment Adviser's methodology in allocating
     certain of its costs to the management of each fund, as well as the
     financial results realized by the Investment Adviser in connection with the
     operation of the Trust. They further considered the profits realized by the
     Investment Adviser and its affiliates from non-fund businesses that may
     benefit from or be related to the Trust's business. The Trustees considered
     the Investment Adviser's profit margins in comparison with the limited
     industry data available. The Trustees concluded that the Investment


42

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


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

     Adviser's profits from management of the Pioneer funds, including the
     financial results derived from the Trust, bear a reasonable relationship to
     the services rendered and are fair for the management of the Trust.

G.   Economies of Scale. The Trustees considered whether the Trust had
     appropriately benefited from any economies of scale, and whether there was
     potential for realization of any further economies of scale. 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
     Trustees concluded that economies of scale were not a relevant
     consideration.

H.   Other Benefits to the Investment Adviser. The Trustees also considered the
     character and amount of fees paid by the Trust, other than under the
     Management Contract, for services provided by the Investment Adviser and
     affiliates. The Trustees further considered the revenues and profitability
     of the Investment Adviser's businesses other than the Trust business,
     including the Investment Adviser's institutional investment advisory
     business. The Trustees considered the intangible benefits that accrue to
     the Investment Adviser and its affiliates by virtue of its relationship
     with the Trust and the Pioneer funds as a group. The Trustees concluded
     that all these types of benefits accruing to the Investment Adviser were
     reasonable in the context of the overall relationship between the
     Investment Adviser and the Trust.

Conclusion. In light of the Investment Adviser's overall performance, the
Trustees considered it appropriate to continue to retain the management services
of the Investment Adviser. Based on their review of the overall nature and
quality of services provided by the Investment Adviser and the fees charged by
other funds in the Trust's relevant peer group, and taking into account all
material factors deemed relevant by the Trustees as well as the advice of
independent counsel, the Trustees concluded that the Management Contract with
the Trust, including the fee payable thereunder, was fair and reasonable and
that its renewal was in the best interests of the Trust and its shareholders.
Accordingly, the Trustees voted to approve the continuation of the Management
Contract for another year.


                                                                              43

 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.

                 project.  In most cases, if
                 the Audit-Related Services are
                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
                 typically well-defined and
                 governed by accounting
                 professional standards (AICPA,
                 SEC, etc.)

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.

Non-Audit Services
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 Trusts 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, 2007 and 2006, there were no services
provided to an affiliate that required the Trusts 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 $17,110 in 2007 and
$15,300 in 2006.  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
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 Trust'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.

The registrant has a separately-designated standing audit
committe eestablished in accordance with Section
3(a)(58)(A) of the Exchange Act (15 U.S.C. 78c(a)(58)(A)).

(b) If applicable, provide the disclosure required by Rule 10A-3(d)
under the Exchange Act (17 CFR 240.10A-3(d)) regarding an exemption
from the listing standards for audit committees.

N/A

Item 6. Schedule of Investments.

File Schedule I Investments in securities of unaffiliated issuers
as of the close of the reporting period as set forth in 210.12-
12 of Regulation S-X [17 CFR 210.12-12], unless the schedule is
included as part of the report to shareholders filed under Item
1 of this Form.

Included in Item 1


ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR
CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

A closed-end management investment company that is filing an annual report on
this Form N-CSR must, unless it invests exclusively in non-voting securities,
describe the policies and procedures that it uses to determine how to vote
proxies relating to portfolio securities, including the procedures that the
company uses when a vote presents a conflict between the interests of its
shareholders, on the one hand, and those of the company's investment adviser;
principal underwriter; or any affiliated person (as defined in Section 2(a)(3)
of the Investment Company Act of 1940 (15 U.S.C. 80a-2(a)(3)) and the rules
thereunder) of the company, its investment adviser, or its principal
underwriter, on the other. Include any policies and procedures of the company's
investment adviser, or any other third party, that the company uses, or that are
used on the company's behalf, to determine how to vote proxies relating to
portfolio securities.

                     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

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 interests 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 interests. 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 that 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 and seeks to align the financial interests of the
portfolio managers with both those of shareholders of the accounts the portfolio
managers manage, through incentive payments based in part on the relative
investment performance of those funds, and also Pioneer through incentive
payments based in part on Pioneer's financial performance. Pioneer's
compensation arrangements with its portfolio managers are determined on the
basis of the portfolio manager's overall services to Pioneer and its affiliates
and not on the basis of specific funds or accounts managed by the portfolio
manager. 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 aligns the financial incentives of Pioneer and the investment
professional. 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 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 Lehman Brothers Municipal Bond Index and the Lehman
         Brothers Non-Investment Grade Municipal Bond Index.  As a result of
         these 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.

Certain portfolio managers participate in an incentive plan whereby senior
executives or other key employees are granted options in stock of Pioneer Global
Asset Management S.p.A., an affiliate of Pioneer, at the then fair value of the
underlying stock. These options are generally exercisable within three years.

Share Ownership by Portfolio Managers. The following table indicates as of March
31, 2007 the value, within the indicated range, of shares beneficially owned by

Item 9. Purchases of Equity Securities by Closed-End Management
Investment Company and Affiliated Purchasers.

(a) If the registrant is a closed-end management investment company,
in the following tabular format, provide the information specified in
paragraph (b) of this Item with respect to any purchase made by or on
behalf of the registrant or any affiliated purchaser, as defined in
Rule 10b-18(a)(3) under the Exchange Act (17 CFR 240.10b-18(a)(3)), of
shares or other units of any class of the registrants equity securities
that is registered by the registrant pursuant to Section 12 of the
Exchange Act (15 U.S.C. 781). Instruction to paragraph (a). Disclose
all purchases covered by this Item, including purchases that do not
satisfy the conditions of the safe harbor of Rule 10b-18 under the
Exchange Act (17 CFR 240.10b-18), made in the period covered by the
report. Provide disclosures covering repurchases made on a monthly basis.
For example, if the reporting period began on January 16 and ended on
July 15, the chart would show repurchases for the months from January 16
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.
