   Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     1


President's Letter

Dear Shareowner,

In 2010, the U.S. economy moved forward on a slow path to recovery. But with
the memory of a deep recession still lingering, businesses and consumers
remained cautious about both investing and spending. While business
fundamentals showed signs of improvement, there was still a reluctance to hire,
and high unemployment remained a problem throughout the year. Wary investors,
concerned about risk, gravitated towards cash and bonds for most of 2010, until
better economic news in the final few months of the year caused a slight shift
in investor sentiment back towards stocks, thus lifting equity returns.

Pioneer remains generally optimistic about the prospects for economic recovery.
The recovery process may occur more slowly than many would like, and may be
accompanied by short-term market swings. But our investment professionals are
finding what we believe are good opportunities to invest in both equities and
bonds.

At Pioneer, we have long advocated the benefits of staying diversified and
investing for the long term. The strategy has generally performed well for many
investors. For instance, bond markets certainly rewarded investors for most of
2010, while equity markets barely budged, even though equity valuations were
inexpensive relative to bonds and compared with historic levels -- conditions
which represented potentially good value for long-term investors. Ultimately,
many of those long-term investors were rewarded when the equity markets finally
rallied over the last few months of 2010.

Pioneer has not changed the basic approach to investing that we have used for
more than 80 years. We remain focused on company fundamentals and risk
management. Our investment process is based on careful research into individual
companies, quantitative analysis, and active portfolio management. This
three-pillared process, which we apply to each of our portfolios, is supported
by an integrated team approach and is designed to carefully balance risk and
reward. Our experienced professionals devote themselves to the careful research
needed to identify investment opportunities in markets around the world.

Our advice, as always, is to work closely with a trusted financial advisor to
discuss your goals and work together to develop an investment strategy that
meets


2     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


your individual needs. There is no single best strategy that works for every
investor.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. We greatly appreciate your trust in us and we thank
you for investing with Pioneer.

Sincerely,

/s/ Daniel K. Kingsbury

   Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     3


Portfolio Management Discussion | 3/31/11

Municipal bonds produced modestly positive returns over the 12 months ended
March 31, 2011, although the overall results masked the dramatic changes in the
investment environment during the period. Municipals generated solid, positive
returns during the first six months of the period, only to suffer the effects
of a severe reversal in investor sentiment in the final three months of 2010,
as the supply of tax-exempt securities increased. The situation somewhat
stabilized in the first quarter of 2011 -- the final three months of the
12-month period -- when supply and demand appeared to come into balance. In the
following interview, David Eurkus discusses the factors that influenced the
performance of Pioneer Municipal High Income Advantage Trust over the 12 months
ended March 31, 2011. Mr. Eurkus is a member of Pioneer's fixed-income team,
which is responsible for the daily management of the Trust.

Q  How did Pioneer Municipal High Income Advantage Trust perform during the 12
   months ended March 31, 2011?

A  Pioneer Municipal High Income Advantage Trust produced a total return of
   2.57% at net asset value, and 4.97% at market price, during the 12 months
   ended March 31, 2011, with common shares of the Trust selling at a 9.5%
   premium to net asset value at the end of the period. During the same 12
   months, the Trust's benchmarks, the Barclays Capital Municipal Bond Index
   and the Barclays Capital High Yield Municipal Bond Index, returned 1.63%
   and 3.28%, respectively. The Barclays Capital Municipal Bond Index is
   designed to track the performance of investment-grade municipal bonds,
   while the High Yield Municipal Bond Index is designed to track the
   performance of lower-rated municipal bonds. Unlike the Trust, the two
   Barclays Capital indices do not use leverage. On March 31, 2011, the 30-day
   SEC yield on the Trust's shares was 9.19%.

Q  Could you describe the investment environment for municipal bonds over the 12
   months ended March 31, 2011, and how the environment influenced the Trust's
   performance?

A  Municipal securities in general struggled in the final quarter of 2010, after
   producing healthy returns when demand for tax-advantaged investments
   steadily increased during the previous six months. Demand for municipal
   bond investments dramatically fell during the last three months of 2010, as
   a heavy issuance of new, tax-exempt municipal bonds entered the market. The
   inflow of new bonds came after it became clear that the Federal government
   would not extend the Build America Bonds (BAB) program, which had
   authorized the issuance of taxable municipal securities subsidized by the
   U.S. Treasury. At the same time that supply was increasing, demand for


4     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


   municipals shrank markedly as many investors fled the market. Among the
   factors that changed during the final quarter of 2010 was a new perception
   that the Federal Reserve System (the Fed) was not likely to undertake a
   third round of quantitative easing, which had been designed to help
   stimulate the economy and had helped support the performance of municipal
   bonds (among other fixed-income securities).

   The election of many new Republican members of Congress also had reduced
   the likelihood that the federal government would authorize further stimulus
   spending, either to spur the economy or to assist state and local
   governments. In addition, well-publicized remarks by one analyst predicting
   the possibility of widespread defaults by municipal securities in the
   following 12 months helped drive many individual investors from the market.
   The result was that the municipal market performed extremely poorly in the
   final quarter of 2010. Municipals fared only somewhat better in the first
   quarter of 2011 -- the final quarter of the Trust's fiscal year -- with the
   general municipal market producing slightly positive results and high-yield
   municipals generating slightly negative results on a total return basis.

   Over the full 12 months ended March 31, 2011, both high-yield and
   investment-grade municipals generated modestly positive performance, with
   high-yielding bonds outperforming higher-quality securities.

   In that environment, the Trust outperformed the Barclays Capital Municipal
   Bond Index, which measures performance of the general municipal market, but
   trailed the Barclays Capital High Yield Municipal Bond Index, which tracks
   the high-yield segment of the municipal market. The performance was
   consistent with the Trust's overall positioning, with exposure to both
   high-yield and investment-grade municipals. At the end of the period (March
   31, 2011), for example, 41.5% of the Trust's total investment portfolio was
   invested in high-yield, below-investment-grade debt, with the remaining
   58.5% of the Trust's total investment portfolio held in higher-quality
   municipals.

Q  How did you position the Trust's portfolio over the 12 months ended March 31,
   2011?

A  We maintained a very consistent positioning during the 12 months ended March
   31, 2011, keeping the Trust's portfolio fully invested, well diversified
   and with an emphasis on credit-worthy assets. We focus on producing
   generous current income for shareowners through investments in securities
   that we believe, as a result of our credit research, are backed by issuers
   that have the ability to pay out consistent, reliable income. We invested
   the Trust almost exclusively in revenue bonds during the 12-month period.
   Revenue bonds rely on revenues from specific funding sources, such as
   hospital health care facilities or colleges/universities or water treatment
   plants, that produce their own fees and revenues. In contrast, general
   obligation bonds


   Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     5


   do not require a dedicated stream of tax revenues to cover that specific
   debt issuance and are more likely to experience downgrades in credit
   quality by various rating agencies due to the current financial problems
   facing many state and local governments. At the end of the Trust's fiscal
   year, only 0.6% of the Trust's total investment portfolio was invested in
   general obligation bonds. Revenue bonds also tend to be issued by sectors
   that are vital to the domestic economy, such as hospitals, universities,
   power generating stations and airports. The two largest groups in the
   Trust's portfolio were bonds backed by health care institutions, which
   represented 33.4% of the Trust's total investment portfolio, and bonds
   backed by transportation facilities -- including airports -- which
   represented 11.2% of the Trust's total investment portfolio.

Q  Could you describe how leverage is used in managing the Trust?

A  The Trust employs leverage provided by auction-preferred shares to invest the
   Trust in additional longer-maturity municipal securities that typically pay
   higher dividends than the dividend rates payable on the preferred shares,
   thereby increasing the Trust's yield. The use of leverage can increase the
   Trust's potential to pay higher yields to its shareowners than would
   generally be paid by an unleveraged portfolio. During periods of low market
   interest rates and modest borrowing costs, the use of leverage can have a
   significant positive effect on the Trust's yield. However, just as the use
   of leverage provides the potential to enhance yield, it also can increase
   investment risk. During periods when municipal bond prices tend to change,
   the use of leverage can magnify the effect of changing prices on the
   Trust's total return, which is the combination of yield and price change.
   When bond prices rise, the use of leverage can further enhance the Trust's
   total return; when bond prices decline, the use of leverage can magnify the
   price loss to the Trust.

Q  How did the level of leverage employed by the Trust change over the Trust's
   fiscal year?

A  During the 12 months ended March 31, 2011, bond prices tended to rise during
   the first six months of the period, and then tended to decline over the
   second six months. At the end of the Trust's fiscal year on March 31, 2011,
   36.0% of the Trust's total managed assets were financed by leverage,
   compared with 34.8% of the Trust's total managed assets being financed by
   leverage at the beginning of the Trust's fiscal year on April 1, 2010. The
   absolute amount of leverage used by the Trust was unchanged over the 12
   months ended March 31, 2011.


6     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


Q  What types of investments most affected the Trust's performance during the 12
   months ended March 31, 2011?

A  The Trust's municipal bond holdings generally performed in line with
   expectations. Most of the areas in which we invested the Trust's assets
   produced positive results during the period. The one area that tended to
   detract from the Trust's performance results were some investments in
   AAA-rated, zero-coupon bonds in the transportation sector. Because
   zero-coupon bonds tend to decline in price more than regular coupon bonds
   when interest rates rise, those holdings suffered greater price loss when
   market interest rates rose in the second half of the Trust's fiscal year.

Q  What is your investment outlook?

A  We think there are good opportunities in the tax-exempt municipal market,
   where bonds are very attractively priced relative to the taxable market.

   We think that the supply of new municipal bonds is likely to be limited,
   based on the extreme reduction in new issuance in the first quarter of
   2011, as state and local governments across the nation embarked on
   austerity programs. At the same time, yields in the municipal market are
   very attractive. Indeed, at the start of the Trust's new fiscal year
   tax-exempt yields were often higher than the yields offered by
   comparable-maturity, comparable-quality taxable bonds. At some point, we
   expect that investors will recognize these values.

   We believe that the general economic backdrop also should support
   investments in municipal securities. The combination of a recovering
   economy, continued low inflation and the Fed's continued accommodative
   monetary policy all should support municipal bonds, including high-yield
   municipal securities.

Please refer to the Schedule of Investments on pages 12-22 for a full listing
of Trust securities.

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


   Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     7


The Trust uses leverage through the issuance of preferred shares. 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. Since
February of 2008, regularly scheduled auctions for the Trust's preferred shares
have failed and preferred shareowners have not been able to sell their shares
at auction. The Board of Trustees of the Trust has considered, and continues to
consider, this issue.

The Trust is required to maintain certain regulatory and rating agency asset
coverage requirements in connection with its outstanding preferred shares. In
order to maintain required asset coverage levels, the Trust may be required to
alter the composition of its investment portfolio or take other actions, such
as redeeming preferred shares with the proceeds from portfolio transactions, at
what might be inopportune times in the market. Such actions could reduce the
net earnings or returns to holders of the Trust's common shares over time.

Risks of investing in the Trust are discussed in greater detail in the Trust's
original offering documents relating to its common shares and shareowner
reports issued from time to time.

These risks may increase share price volatility.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

Any information in this shareowner report regarding market or economic trends
or the factors influencing the Trust's historical or future performance are
statements of the opinion of Trust management as of the date of this report.
These statements should not be relied upon for any other purposes.

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 NAV due to such factors as interest rate
changes and the perceived credit quality of borrowers.

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

Closed-end funds, unlike open-end funds, are not continuously offered. There is
a one-time public offering and, once issued, shares of closed-end funds are
sold in the open market through a stock exchange, and frequently trade at
prices lower than their NAV. NAV per common share 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 sale of Trust shares.

Index comparison begins October 31, 2003. The Barclays Capital Municipal Bond
Index is a broad measure of the municipal bond market. Barclays Capital High
Yield 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. The indices are
not leveraged. You cannot invest directly in the indices.

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
investment objective of the Trust is to seek a high level of current income
exempt from regular federal income tax, and the Trust may seek capital
appreciation to the extent that it is consistent with its primary investment
objective.

At times, the Trust's investments may represent industries or industry sectors
that are interrelated or have common risks, making the Trust more susceptible
to any economic, political, or regulatory developments or other risks affecting
those industries and sectors. 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 principal risks.

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.

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, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gain or loss 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:

   supplied by independent pricing services, which consider such factors as
   market prices, market events, quotations from one or more brokers, Treasury
   spreads, yields, maturities 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. Equity securities that have
   traded on an exchange are valued at the last sale price on the principal
   exchange where they are traded. Equity securities that have not traded on
   the date of valuation, or securities for which sale prices are not
   available, generally are valued using the mean between the last bid and
   asked prices. Securities for which independent pricing services are unable
   to supply prices or for which market prices and/or quotations are not
   readily available or are considered to be unreliable are valued using fair
   value methods pursuant to procedures adopted by the Board of Trustees.

   The Trust may use fair value methods if it is determined that a significant
   event has occurred after the close of the exchange or market on which the
   security trades and prior to the determination of the Trust's net asset
   value. Thus, the valuation of the Trust's securities may differ from
   exchange prices.

   At March 31, 2011, there were no securities that were valued using fair
   value methods (other than securities valued using prices supplied by
   independent pricing services). Inputs used when applying fair value methods
   to value a security may include credit ratings, the financial condition of
   the company, current market conditions and comparable securities. Short-term
   fixed income securities with remaining maturities of sixty days or less
   generally are valued at amortized cost. Money market mutual funds are valued
   at net asset value.

   Discount and premium on debt securities are accreted or amortized,
   respectively, daily into interest income on a yield-to-maturity basis with a
   corresponding increase or decrease in the cost basis of the security.
   Interest income, including interest-bearing cash accounts, is recorded on an
   accrual basis.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Trust becomes aware of the ex-dividend data in
   the exercise of reasonable diligence.

   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. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.

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

   At March 31, 2011, the Trust reclassified $21,306 to decrease undistributed
   net investment income and to decrease net realized loss on investments to
   reflect permanent book/tax differences. The reclassification has no impact
   on the net assets of the Trust and presents the Trust's capital accounts on
   a tax basis.

   At March 31, 2011, the Trust had a net capital loss carryforward of
   $53,183,034, of which the following amounts will expire between 2014 and
   2019 if not utilized: $14,156,085 in 2014, $311,368 in 2016, $17,813,537 in
   2017, $18,242,633 in 2018 and $2,659,411 in 2019.

   The Trust has elected to defer approximately $2,141,689 of capital losses
   recognized between November 1, 2010 and March 31, 2011 to its fiscal year
   ending March 31, 2012.

   The tax character of distributions paid to common and preferred shareowners
   during the years ended March 31, 2011 and March 31, 2010 was as follows:



--------------------------------------------------------------------------------
                                                          2011             2010
--------------------------------------------------------------------------------
                                                              
   Distributions paid from:
   Tax exempt income                               $24,632,869      $22,779,781
   Ordinary income                                     533,423           80,715
--------------------------------------------------------------------------------
     Total                                         $25,166,292      $22,860,496
================================================================================


30     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


   The following shows the components of distributable earnings (losses) on a
   federal income tax basis at March 31, 2011:





--------------------------------------------------------------------------------
                                                                           2010
--------------------------------------------------------------------------------
                                                               
   Distributable earnings:
   Undistributed tax-exempt income                                 $  9,407,467
   Undistributed ordinary income                                         35,116
   Capital loss carryforward                                        (53,183,034)
   Post-October-loss deferred                                        (2,141,689)
   Dividends payable                                                     (6,377)
   Unrealized depreciation                                          (15,725,538)
--------------------------------------------------------------------------------
     Total                                                         $(61,614,055)
================================================================================


   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, book/tax
   difference in accrual of income on securities in default, and other
   temporary differences.

C. Class Actions

   During the year ended March 31, 2011 the Trust recognized gains of $81,281
   in settlement of class action lawsuit from several different companies, as
   reflected on the Statement of Operations.

D. Automatic Dividend Reinvestment Plan

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

   If a shareowner's shares are held in the name of a brokerage firm, bank or
   other nominee, the shareowner can ask the firm or nominee to participate in
   the Plan on the shareowner's behalf. If the firm or nominee does not offer
   the Plan, dividends will be paid in cash to the shareowner of record. A firm
   or nominee may reinvest a shareowner's cash dividend in common shares of the
   Trust on terms that differ from the terms of the Plan.


  Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     31


   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), the Trust's investment adviser, a
wholly owned indirect subsidiary of UniCredit S.p.A. (UniCredit), 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" means (a) the total assets of
the Trust, including any form of investment leverage, minus (b) all accrued
liabilities incurred in the normal course of operations, which shall not
include any liabilities or obligations attributable to investment leverage
obtained through (i) indebtedness of any type (including, without limitation,
borrowing through a credit facility of the issuance of debt securities), (ii)
the issuance of preferred stock or other similar preference securities, and/or
(iii) any other means. For the year ended March 31, 2011, the net management
fee was 0.60% of the Trust's average daily managed assets, which was equivalent
to 0.92% 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, 2011, $222,082 was payable to PIM related to management costs,


32     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


administrative costs and certain other reimbursements and is included in "Due
to affiliates" on the Statement of Assets and Liabilities.

Effective September 1, 2010 PIM has retained State Street Bank and Trust
Company (State Street) to provide certain administrative and accounting
services to the Trust on its behalf. For such services, PIM pays State Street a
monthly fee at an annual rate of 0.07% of the Trust's average daily managed
assets up to $500 million and 0.03% for average daily managed assets in excess
of $500 million, subject to a minimum monthly fee of $10,000. Previously, PIM
had retained Princeton Administrators, LLC (Princeton) to provide such
services. PIM paid Princeton a monthly fee at an annual rate of 0.07% of the
Trust's average daily managed assets up to $500 million and 0.03% for average
daily managed assets in excess of $500 million, subject to a minimum monthly
fee of $10,000. Neither State Street nor Princeton received compensation
directly from the Trust for providing such services.

3. Transfer Agents

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

In addition, the Trust reimburses PIMSS for out-of-pocket expenses incurred by
PIMSS related to shareowner communications activities such as proxy and
statement mailings and outgoing phone calls.

4. 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


  Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     33


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 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. Risk may also arise
with regard to market movements in the value of the swap arrangement that do
not exactly offset the changes in the related dividend requirement or interest
expense on the Trust's leverage.

There were no interest rate swap contracts outstanding at March 31, 2011.

5. Trust Shares

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

Transactions in common shares of beneficial interest for the years ended March
31, 2011 and March 31, 2010 were as follows:



--------------------------------------------------------------------------------
                                                        3/31/11          3/31/10
--------------------------------------------------------------------------------
                                                                
 Shares outstanding at beginning of year             22,995,047       22,879,496
 Reinvestment of distributions                          138,744          115,551
--------------------------------------------------------------------------------
 Shares outstanding at end of year                   23,133,791       22,995,047
================================================================================


The Trust may classify or reclassify any unissued shares of beneficial interest
into one or more series of preferred shares of beneficial interest. As of March
31, 2011, 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 to be
reset every seven days based on the results of an auction. An auction fails if
there are more APS offered for sale than there are buyers. When an auction
fails, the dividend rate for the period will be the maximum rate on the auction
dates described in the prospectus for the APS. Preferred shareowners are not
able to sell their APS at an auction if the auction fails. Since February 2008,
the Trust's auctions related to the APS have failed. The maximum rate for each
series is 125% of the 7 day commercial paper rate or adjusted Kenny rate.
Dividend rates on APS ranged from 0.398% to 0.665% during the year ended March
31, 2011.


34     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


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, the Trust does not comply with the asset coverage
ratios described in the prospectus for the APS.

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 Statement of
Preferences 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. 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.

6. Subsequent Events

The Board of Trustees of the Trust declared on April 15, 2011 a dividend from
undistributed net investment income of $0.090 per common share payable April
29, 2011, to common shareowners of record.

Subsequent to March 31, 2011, dividends declared and paid on preferred shares
totaled $62,520 in aggregate for the two outstanding preferred share series
through May 10, 2011.

In preparing these financial statements, PIM has evaluated the impact of all
events and transactions for potential recognition or disclosure and has
determined that other than disclosed above, there were no subsequent events
requiring recognition or disclosure in the financial statements.

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, 2011, and the related statement of operations for
the year then ended, the statements of changes in net assets for each of the
two years in the period then ended, and the financial highlights for each of
the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. We were not engaged to perform an audit of the Trust's internal
control over financial reporting. Our audits included consideration of internal
control over financial reporting as a basis for designing audit procedures that
are appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Trust's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating
the overall financial statement presentation. Our procedures included
confirmation of securities owned as of March 31, 2011, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Pioneer Municipal High Income Advantage Trust at March 31, 2011, the results of
its operations for the year then ended, the changes in its net assets for each
of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended, in conformity with U.S.
generally accepted accounting principles.

Approval of Investment Advisory Agreement

Pioneer Investment Management, Inc. (PIM) serves as the investment adviser to
Pioneer Municipal High Income Advantage Trust (the Trust) pursuant to an
investment advisory agreement between PIM and the Trust. In order for PIM to
remain the investment adviser of the Trust, the Trustees of the Trust must
determine annually whether to renew the investment advisory agreement for the
Trust.

The contract review process began in March 2010 as the Trustees of the Trust
agreed on, among other things, an overall approach and timeline for the
process. In July 2010, the Trustees approved the format of the contract review
materials and submitted their formal request to PIM to furnish information
necessary to evaluate the terms of the investment advisory agreement. The
contract review materials were provided to the Trustees in July 2010 and
September 2010. After reviewing and discussing the materials, the Trustees
submitted a request for additional information to PIM, and materials were
provided in response to this request. Meetings of the Independent Trustees of
the Trust were held in July, September, October, and November, 2010 to review
and discuss the contract review materials. In addition, the Trustees took into
account the information related to the Trust provided to the Trustees at each
regularly scheduled meeting.

At a meeting held on November 16, 2010, based on their evaluation of the
information provided by PIM and third parties, the Trustees of the Trust,
including the Independent Trustees voting separately, unanimously approved the
renewal of the investment advisory agreement for another year. In considering
the renewal of the investment advisory agreement, the Trustees considered
various factors that they determined were relevant, including the factors
described below. The Trustees did not identify any single factor as the
controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

The Trustees considered the nature, extent and quality of the services that had
been provided by PIM to the Trust, taking into account the investment objective
and strategy of the Trust. The Trustees reviewed the terms of the investment
advisory agreement. The Trustees also reviewed PIM's investment approach for
the Trust, its research process and its process for trade execution. The
Trustees considered the resources of PIM and the personnel of PIM who provide
investment management services to the Trust. The Trustees considered the
non-investment resources and personnel of PIM involved in PIM's services to the
Trust, including PIM's compliance and legal resources and personnel. In
addition, the Trustees considered the arrangements put in place to retain key


38     Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11


investment and other personnel. The Trustees also considered the substantial
attention and high priority given by PIM's senior management to the Pioneer
fund complex.

The Trustees considered that PIM supervises and monitors the performance of the
Trust's service providers and provides the Trust with personnel (including
Trust officers) and other resources that are necessary for the Trust's business
management and operations. The Trustees also considered that, as administrator,
PIM is responsible for the administration of the Trust's business and other
affairs. The Trustees considered the fees paid to PIM for the provision of
administration services.

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

Performance of the Trust

The Trustees considered the performance results of the Trust over various time
periods. They reviewed information comparing the Trust's performance with the
performance of its peer group of funds as classified by Morningstar, Inc.
(Morningstar), an independent provider of investment company data, and with the
performance of the Trust's benchmark index. The Trustees considered that the
Trust's annualized total return was in the first quintile of its Morningstar
category for the one year period ended June 30, 2010, and in the fourth
quintile of its Morningstar category for the three and five year periods ended
June 30, 2010. (In all quintile rankings referred to throughout this
disclosure, first quintile is most favorable to the Trust's shareowners. Thus,
highest relative performance would be first quintile and lowest relative
expenses would also be first quintile.) The Trustees noted that the yield of
the Trust compared favorably to the yield of the Trust's benchmarks as of June
30, 2010. The Trustees reviewed data provided by PIM showing how leverage had
benefited the Trust's common shareholders. The Trustees concluded that the
investment performance of the Trust was satisfactory.

Management Fee and Expenses

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

The Trustees considered that the Trust's management fee rate based on common
shares assets for the twelve months ended June 30, 2010 was in the fifth
quintile relative to the management fees paid by other funds in its Strategic
Insight peer group for the comparable period. The Trustees considered the
effect of leverage on the Trust's management fee relative to its peers by
reviewing the management fee ratios of the Trust and its peers based on managed



  Pioneer Municipal High Income Advantage Trust | Annual Report | 3/31/11     39


assets rather than common shares assets. They noted that, on that basis, the
Trust's management fee for the twelve months ended June 30, 2010 was in the
third quintile relative to the Trust's peer group for the comparable period.

The Trustees also considered that the Trust's expense ratio based on common
shares assets for the twelve months ended June 30, 2010 was in the fourth
quintile relative to its Strategic Insight peer group for the comparable
period. The Trustees noted the impact of the Trust's higher relative management
fee on its expense ratio and considered that the Trust's expense ratio was
slightly more than one basis point higher than the median expense ratio of the
Trust's peer group.

The Trustees also reviewed management fees charged by PIM to its institutional
and other clients. In evaluating the fees associated with PIM's client
accounts, the Trustees took into account the respective demands, resources and
complexity associated with the Trust and client accounts. The Trustees noted
that in some instances the fee rates for those clients were lower than the
management fee for the Trust and considered that, under the investment advisory
agreement with the Trust, PIM performs additional services for the Trust that
it does not provide to those other clients or services that are broader in
scope, including oversight of the Trust's other service providers and
activities related to compliance and the extensive regulatory and tax regimes
to which the Trust is subject. The Trustees concluded that the management fee
payable by the Trust to PIM was reasonable in relation to the nature and
quality of the services provided by PIM.

Profitability

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

Economies of Scale

The Trustees considered the extent to which PIM may realize economies of scale
or other efficiencies in managing and supporting the Trust. Since the Trust is
a closed-end fund that has not raised additional capital, the Trustees
concluded that economies of scale were not a relevant consideration in the
renewal of the investment advisory agreement.

Other Benefits

The Trustees considered the other benefits to PIM from its relationship with
the Trust. The Trustees considered the character and amount of fees paid by the
Trust, other than under the investment advisory agreement, for services
provided by PIM and its affiliates. The Trustees further considered the
revenues and profitability of PIM's businesses other than the fund business.
The Trustees considered the intangible benefits to PIM by virtue of its
relationship with the Trust and the other Pioneer funds. The Trustees concluded
that the receipt of these benefits was reasonable in the context of the overall
relationship between PIM and the Trust.

Conclusion

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

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

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

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

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

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

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

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

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

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

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

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


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

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 Trust's audit committee is
required to pre-approve services to affiliates defined by
SEC rules to the extent that the services are determined
to have a direct impact on the operations or financial
reporting of the Trust. For the years ended March 31,
2011 and 2010, there were no services provided to an
affiliate that required the Trust's audit committee pre-
approval.

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

N/A

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

The aggregate non-audit fees for the Trust and affiliates,
as previously defined, totaled approximately $17,942 in
2011 and $17,942 in 2010.


(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
committee established 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 interest are increased to the extent that a portfolio manager
has a financial incentive to favor one account over another. Pioneer has
structured its compensation arrangements in a manner that is intended to limit
such potential for conflicts of interest.  See "Compensation of Portfolio
Managers" below.

-     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.

-     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.

-     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.

-     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.

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

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

-     Quantitative Investment Performance. The quantitative investment
performance calculation is based on pre-tax investment performance of all of the
accounts managed by the portfolio manager (which includes the fund and any other
accounts managed by the portfolio manager) over a one-year period (20%
weighting) and four-year period (80% weighting), measured for periods ending on
December 31. The accounts, which include the fund, are ranked against a group of
mutual funds with similar investment objectives and investment focus (60%) and a
broad-based securities market index measuring the performance of the same type
of securities in which the accounts invest (40%), which, in the case of the
fund, are the Barclays Capital Municipal Bond Index and the Barclays Capital
High Income Municipal Bond Index. As a result of these two benchmarks, the
performance of the portfolio manager for compensation purposes is measured
against the criteria that are relevant to the portfolio manager's competitive
universe.
-     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.
-     Pioneer Results and Business Line Results. Pioneer's financial
performance, as well as the investment performance of its investment management
group, affect a portfolio manager's actual bonus by a leverage factor of plus or
minus (+/-) a predetermined percentage.

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

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

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.
