                                 INTRODUCTION

     This proxy statement is being used by the Board of Trustees of each fund
to solicit proxies to be voted at the annual meeting of shareholders of each of
the funds referenced above. Participating in the meeting are holders of common
shares of beneficial interest (the "Common Shares") and the holders of
preferred shares of beneficial interest (the "Preferred Shares") of each fund.
The Common Shares and the Preferred Shares of each fund sometimes are referred
to herein collectively as the "Shares". Each meeting will be held at the
offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, 26th
Floor, Boston, Massachusetts 02109, at 2:00 p.m., Boston time, on August 16,
2005, and at any adjournments of a meeting to a later date, for the purposes as
set forth in the accompanying notice of annual meeting of shareholders.

     This proxy statement and the enclosed proxy card are being mailed to
shareholders of each fund on or about July 11, 2005. The annual report for each
fund for its most recently completed fiscal year was previously mailed to
shareholders.

                            WHO IS ELIGIBLE TO VOTE

     Shareholders of record of each fund as of the close of business on June
21, 2005 (the "record date") are entitled to vote on all of the fund's business
at the annual shareholder meeting and any adjournments thereof. The affirmative
vote of a plurality of the Common and Preferred Shares of each fund present at
the meeting in person or by proxy, voting together as a single class, is
required to elect each nominee for Trustee designated to be elected by the
Common and Preferred Shares of each fund. Election by


                                       1


plurality means those persons who receive the highest number of votes cast
"FOR" up to the total number of persons to be elected as Trustees at the
Meeting shall be elected. Shares represented by properly executed proxies,
unless revoked before or at the meeting, will be voted according to the
shareholder's instructions. If you sign a proxy but do not fill in a vote, your
shares will be voted in favor of each of the nominees for Trustee. If any other
business comes before the annual shareholder meeting, your shares will be voted
at the discretion of the persons named as proxies.

     Each fund will vote separately on each item. Votes of multiple funds will
not be aggregated.

                                  PROPOSAL 1

                         ELECTION OF BOARD OF TRUSTEES

     Shareholders of each fund are being asked to consider the election of
three nominees to the Board of Trustees of each fund. All of the nominees for
election to each fund's Board currently serve as Trustees for the fund and have
served in that capacity continuously since originally elected or appointed.
Each Trustee shall be elected to hold office for a three year term or until his
or her successor is elected and qualified. Each nominee has consented to being
named in this proxy statement and indicated his or her willingness to serve if
elected. In the unanticipated event that any nominee should be unable to serve,
the persons named as proxies may vote for such other person as shall be
designated by the fund's Board of Trustees. The persons named on the
accompanying proxy card intend to vote at the meeting (unless otherwise
directed) for the election of the nominees named below as Trustees of each
fund.

     The Declaration of Trust for each fund provides that the Board of Trustees
shall consist of Trustees divided into three classes, the classes to be as
nearly equal in number as possible. The Trustees of only one class are elected
at each annual meeting so that the regular term of only one class of Trustees
will expire annually and any particular Trustee stands for election only once
in each three year period. Each fund's Board of Trustees is divided into three
staggered term classes -- Class I, Class II and Class III. Class I Trustees are
being submitted to shareholders for election at the meeting for Pioneer Tax
Advantaged Balanced Trust. Class II Trustees are being submitted to
shareholders for election at the Meeting for Pioneer Municipal High Income
Trust and Pioneer Municipal High Income Advantage Trust. Class III Trustees are
being submitted to shareholders for election at the Meeting for Pioneer High
Income Trust.

     Each fund's Board of Trustees consists of eight members.

Pioneer High Income Trust
     The terms of the Class I Trustees -- Ms. Bush and Ms. Piret -- will expire
in 2006; the terms of the Class II Trustees -- Mr. Cogan, Mr. Bock and Mr.
West -- expire in 2007; and the terms of the Class III Trustees -- Ms. Graham,
Mr. Hood and Mr. Winthrop -- expire at the upcoming 2005 annual meeting.


                                       2


Pioneer Municipal High Income Trust and
Pioneer Municipal High Income Advantage Trust

     The terms of the Class I Trustees for Pioneer Municipal High Income Trust
and Pioneer Municipal High Income Advantage Trust  -- Mr. Cogan, Mr. Bock and
Mr. West -- expire in 2007; the terms of the Class II Trustees -- Ms. Graham,
Mr. Hood and Mr. Winthrop -- expire at the upcoming 2005 annual meeting; and
the terms of the Class III Trustees -- Ms. Bush and Ms. Piret -- expire in
2006.

Pioneer Tax Advantaged Balanced Trust

     The terms of the Class I Trustees -- Ms. Graham, Mr. Hood and Mr.
Winthrop -- will expire at the first annual meeting following the initial
public offering of the common shares (the upcoming meeting); the terms of the
Class II Trustees -- Ms. Bush and Ms. Piret -- will expire in 2006; and the
terms of the Class III Trustees -- Mr. Cogan, Mr. Bock and Mr. West -- expire
in 2007.

     Subsequently, for each fund, each class of Trustees will stand for
election at the conclusion of its respective three year term. Such
classification may prevent replacement of a majority of the Trustees for up to
a two-year period. Mr. Cogan and Ms. Piret have been designated as the Trustees
to be elected by the holders of the Preferred Shares of each fund.

     The following table sets forth the incumbent Trustees and each Trustee's
position(s) with each fund, his or her age, address, principal occupation and
employment during the past five years and any other directorship held. Trustees
who are interested persons of a fund within the meaning of the Investment
Company Act of 1940 (the "1940 Act") are referred to as Interested Trustees.
Trustees who are not interested persons of a fund are referred to as
Independent Trustees. Each of the Trustees serves as a Trustee of each of the
81 U.S. registered investment portfolios for which Pioneer Investment
Management, Inc. ("Pioneer") serves as investment adviser (the "Pioneer
Funds"). The address of all Interested Trustees is 60 State Street, Boston, MA
02109.

     All members of the Audit Committee are "independent", as defined in the
applicable listing standard of the New York Stock Exchange currently in effect.
The Board of Trustees has adopted a charter for the Audit Committee, in effect
as of March 15, 2005, which is attached as Appendix A to this proxy statement.
In accordance with its charter, the purposes of the Audit Committee are to:

   o  act as a liaison between the fund's independent registered public
      accounting firm and the full Board of Trustees of the fund;

   o  discuss with the fund's independent registered public accounting firm
      their judgments about the quality of the fund's accounting principles and
      underlying estimates as applied in the fund's financial reporting;


                                       10


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

   o  review and approve insurance coverage and allocations of premiums between
      the management and the fund and among the Pioneer Funds;

   o  review and approve expenses under the administration agreement between
      Pioneer and the fund and allocations of such expenses among the Pioneer
      Funds; and

   o  receive on a periodic basis a formal written statement delineating all
      relationships between the independent registered public accounting firm
      and the fund or Pioneer; to actively engage in a dialogue with the
      independent registered public accounting firm with respect to any
      disclosed relationships or services that may impact the objectivity and
      independence of the independent registered public accounting firm; and to
      recommend that the Trustees take appropriate action in response to the
      independent registered public accounting firm's report to satisfy itself
      of the firm's independence.

     The Audit Committee reports that it has (1) reviewed and discussed each
fund's audited financial statements with management; (2) discussed with the
independent registered public accounting firm the matters relating to the
quality of each fund's financial reporting; and (3) received written
disclosures and an independence letter from the independent registered public
accounting firm and discussed with the independent registered public accounting
firm that firm's independence. Based upon the review and discussions referred
to above, the Audit Committee recommended to the Board of Trustees that the
audited financial statements be included in the Annual Reports for Pioneer High
Income Trust and Pioneer Municipal High Income Advantage Trust for the fiscal
year ended March 31, 2005, the Annual Report for Pioneer Municipal High Income
Trust for the fiscal year ended April 30, 2005 and the Annual Report for
Pioneer Tax Advantaged Balanced Trust for the fiscal year ended November 30,
2004, for filing with the Securities and Exchange Commission (the "SEC").

     The members of the Audit Committee are David R. Bock, Margaret B.W. Graham
and Marguerite A. Piret (Chair).

     All members of the Nominating Committee are independent under the New York
Stock Exchange's Revised Listing Rules and are not interested persons, as
defined in the 1940 Act, of Pioneer. The Board of each fund has adopted a
written charter for the Nominating Committee, which is available on Pioneer's
website: www.pioneerfunds.com. The Nominating Committee reviews the
qualifications of persons being considered as candidates as Trustees and makes
recommendations regarding the qualifications of such persons to the Independent
Trustees. All of the Independent Trustees then evaluate any candidate and
determine whether to nominate them for election. The Trustees who are not
Independent Trustees and the officers of each Fund are nominated and selected
by the Board.


                                       11


     The Nominating Committee's charter provides for certain criteria to be
used in evaluating candidates for Independent Trustee. In reviewing a potential
nominee and in evaluating the re-nomination of current Independent Trustees,
the Nominating Committee applies the following criteria: (i) the nominee's
reputation for integrity, honesty and adherence to high ethical standards, (ii)
the nominee's business acumen and ability to exercise sound judgments, (iii) a
commitment to attend and participate in meetings of the Board and its
committees, (iv) the ability to understand potential conflicts of interest in
managing a fund and to act in the interests of all shareholders, and (v) the
absence of a real or apparent conflict of interest that would impair the
nominee's ability to represent the interests of all the shareholders and to
fulfill the responsibilities of an Independent Trustee. The Nominating
Committee does not necessarily place the same emphasis on each criteria and
each nominee may not have each of these qualities.

     As long as an existing Independent Trustee continues, in the opinion of
the other Independent Trustees, to satisfy these criteria and continues to make
positive contributions to the Board, each fund anticipates that Independent
Trustees of each fund would favor the re-nomination of an existing Trustee
rather than a new candidate. Consequently, while the Nominating Committee will
evaluate the qualifications of nominees recommended by shareholders to serve as
Trustee, the Independent Trustees may only act upon the Nominating Committee's
evaluation if there is a vacancy on the Board. In the event that a vacancy
arises or a change in Board membership is determined to be advisable, the
Nominating Committee will, in addition to any shareholder recommendations,
evaluate candidates identified by other means, including candidates proposed by
Independent Trustees or management. While it has not done so in the past, the
Nominating Committee may retain a consultant to assist the Committee in a
search for a qualified candidate.

     Any shareholder recommendation must be submitted in compliance with all of
the pertinent provisions of Rule 14a-8 under the Securities Exchange Act of
1934 (the "Exchange Act") to be considered by the Nominating Committee. In
evaluating a nominee recommended by a shareholder, the Nominating Committee, in
addition to the criteria discussed above, may consider the objectives of the
shareholder in submitting that nomination and whether such objectives are
consistent with the interests of all shareholders. If the Board determines to
include a shareholder's candidate among the slate of nominees, the candidate's
name will be placed on the fund's proxy card. If the Nominating Committee, the
Independent Trustees or the Board determines not to include such candidate
among the Board's designated nominees and the shareholder has satisfied the
requirements of Rule 14a-8, the shareholder's candidate will be treated as a
nominee of the shareholder who originally nominated the candidate.

     The Nominating Committee initiated the recommendation of each of the
nominees to serve as Independent Trustee.

     Shareholders may communicate with the members of the Board as a group or
individually. Any such communication should be sent to the Board or an
individual Trustee c/o the Secretary of the fund at the address on the notice
of this meeting. The Secretary


                                       12


may determine not to forward any letter to members of the Board that does not
relate to the business of a fund.

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

     The Policy Administration Committee reviews the implementation of certain
of each fund's administrative policies and procedures.

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

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

     During each fund's most recent fiscal year, the Board of Trustees held 10
meetings. All of the current Trustees and committee members of each fund then
serving attended at least 75% of the meetings of the Board of Trustees and
applicable committees, if any, held during that fund's fiscal year.

     The following table indicates the value of shares that each Trustee or
nominee beneficially owned in each fund and Pioneer Funds in the aggregate as
of May 31, 2005. Beneficial ownership is determined in accordance with SEC
rules. The share value of any closed-end Pioneer fund is based on its closing
market price on May 31, 2005. The share value of any open-end Pioneer fund is
based on the net asset value of the class of shares on May 31, 2005. The dollar
ranges in this table are in accordance with SEC requirements.

     For each of the funds, during the most recent fiscal year, none of the
Trustees or any nominee for election as a Trustee engaged in the purchase or
sale of securities of Pioneer, UniCredito Italiano or any other entity in a
control relationship to Pioneer or Pioneer Funds Distributor, Inc. ("PFD").

Material Relationships of the Independent Trustees

     For purposes of the statements below:

     o  the immediate family members of any person are their spouse, children
        in the person's household (including step and adoptive children) and
        any dependent of the person.

     o  an entity in a control relationship means any person who controls, is
        controlled by or is under common control with the named person. For
        example, UniCredito Italiano is an entity that is in a control
        relationship with Pioneer.

     o  a related fund is a registered investment company or an entity exempt
        from the definition of an investment company pursuant to Sections
        3(c)(1) or 3(c)(7) of the 1940 Act, for which Pioneer or any of its
        affiliates act as investment adviser or for which PFD or any of its
        affiliates act as principal underwriter. For example, each fund's
        related funds include all of the Pioneer Funds and any non-U.S. funds
        managed by Pioneer or its affiliates.

     As of December 31, 2004, for each fund, none of the Independent Trustees,
nor any of their immediate family members, beneficially owned any securities
issued by Pioneer, UniCredito Italiano or any other entity in a control
relationship to Pioneer or PFD.

     During the past five years, for each fund, none of the Independent
Trustees, nor any of their immediate family members, had any direct or indirect
interest (the value of which exceeded $60,000), whether by contract,
arrangement or otherwise, in Pioneer, UniCredito Italiano, or any other entity
in a control relationship to Pioneer or PFD.

     During the past five years, for each fund, none of the Independent
Trustees, nor any of their immediate family members, had an interest in a
transaction or a series of transactions, or in any currently proposed
transaction, or series of similar transactions, in which the aggregate amount
involved exceeded $60,000 and to which any of the following were a party (each

o  a related fund

o  an officer of any related fund

o  Pioneer or PFD

o  an officer of Pioneer or PFD

o  any affiliate of Pioneer or PFD

o  an officer of any such affiliate


                                       15


     During the calendar years 2003 and 2004, for each fund, none of the
Independent Trustees, nor any of their immediate family members, had any
relationship (the value of which exceeded $60,000) with any fund related party,
including, but not limited to, relationships arising out of (i) the payment for
property and services, (ii) the provision of legal services, (iii) the
provision of investment banking services (other than as a member of the
underwriting syndicate) or (iv) the provision of consulting services, except
that Mr. West, an Independent Trustee, is Senior Counsel to Sullivan & Cromwell
and acts as counsel to the Independent Trustees and the Independent Trustees of
the other Pioneer Funds. The aggregate compensation paid to Sullivan & Cromwell
by the funds and the other Pioneer Funds was approximately $126,603 and
$208,010 in 2003 and 2004, respectively.

     During the calendar years 2003 and 2004, for each fund, none of the

member of a board of directors on which an officer of any of the following
entities also serves as a director:

o  PFD

o  UniCredito Italiano

o  any other entity in a control relationship with Pioneer or PFD

     None of the funds' Trustees or officers has any arrangement with any other
person pursuant to which that Trustee or officer serves on the Board of
Trustees. During the calendar years 2003 and 2004, for each fund, none of the
Independent Trustees, nor any of their immediate family members, had any
position, including as an officer, employee, director or partner, with any of
the following:

o  the fund

o  any related fund

o  Pioneer

o  PFD

o  any affiliated person of the fund, Pioneer or PFD

o  UniCredito Italiano

o  any other entity in a control relationship to the fund, Pioneer or PFD

Compliance with Section 16(a) Reporting Requirements

     Section 16(a) of the Exchange Act requires each fund's executive officers,
Trustees and person who own more than ten percent of a fund's shares ("10%
Shareholders") to file reports of ownership and changes in ownership with the
SEC. Executive officers, Trustees and 10% Shareholders are required by SEC
regulations to furnish the fund with copies of all Section 16(a) forms they
file. Based solely on a review of the copies of these reports furnished to each
of the funds and representations that no other reports were required to be
filed, each fund believes that during the past fiscal year its executive


                                       16


officers, Trustees and 10% Shareholders complied with all applicable Section
16(a) filing requirements.

Other executive officers

     In addition to Mr. Cogan and Mr. Hood, who serve as President and
Executive Vice President, respectively, of each fund, the following table
provides information with respect to the other executive officers of the funds.
Each executive officer is elected by the Board of Trustees and serves until his
or her successor is chosen and qualified or until his or her resignation or
removal by the Board. The business address of all officers of the funds is 60

Investment adviser and administrator

     Pioneer, whose executive offices are located at 60 State Street, Boston,
Massachusetts 02109, serves as investment adviser and administrator to each
fund.

     The Trustees may, but generally do not, attend shareholder meetings. No
trustees attended the 2004 annual shareholder meeting.

Required vote

     In accordance with each fund's agreement and declaration of trust, the
holders of Common Shares and Preferred Shares of each fund will vote on the
respective nominees designated to be elected by such class of shares. Ms.
Graham, Mr. Hood and Mr. Winthrop are the current nominees for election for
each fund, each by the holders of Common and Preferred Shares. The affirmative
vote of a plurality of the Common and Preferred Shares for each fund present at
the meeting in person or by proxy, voting together as a single class, is
required to elect such nominee for Trustee designated to be elected by the
Common and Preferred Shares. This means that the three nominees receiving the
greatest number of votes will be elected as Class II Trustees to the Board of
Pioneer Municipal High Income Trust and Pioneer Municipal High Income Advantage
Trust, Class III Trustees to the Board of Pioneer High Income Trust and Class I
Trustees to the Board of Pioneer Tax Advantaged Balanced Trust.

Recommendation

     For the reasons set forth above, the Trustees of your fund unanimously
recommend that shareholders vote in favor of each of the nominees.

All other fees

Affiliates' Fees for Non-Audit Services Required to be Pre-Approved

     Beginning with non-audit service contracts entered into on or after May 6,
2003, the effective date of the new SEC pre-approval rules, each fund's audit
committee is required to pre-approve services to affiliates as 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 fund. Affiliates include the
fund's investment adviser and any entity controlling, controlled by, or under
common control with the adviser that provides ongoing services to the fund
(hereinafter referred to as "affiliates" of the fund). For the years ended
December 31, 2004 and 2003, for each of the funds, there were no services
provided to an affiliate that required the fund's audit committee pre-approval.

General Audit Committee Approval Policy

o    For all projects, the officers of the funds and the funds' independent
     registered public accounting firm 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 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
     independent registered public accounting firm as set forth in the above
     policy.

Aggregate Non-Audit Fees

     The aggregate non-audit fees for each fund and its affiliates as
previously defined, were as follows. These fees include services provided prior
to May 6, 2003, the effective date of the pre-approval process.

meeting (either in person or via telephone), will have the opportunity to make

Shareholder proposals

     If you wish to include a proposal in your fund's proxy statement for the
2006 annual meeting, your proposal must be received by the Secretary of the
fund at the fund's principal offices at 60 State Street, Boston Massachusetts
02109 on or before April 11, 2006. A proposal that is not to be included in the
fund's proxy statement may only be made at the 2006 annual meeting if it is
received by the Secretary of the fund at the fund's principal offices at 60
State Street, Boston Massachusetts 02109 not more than 120 days and at least 90
days before the anniversary date of the mailing of the fund's proxy materials
for this year's annual meeting provided, however, that in the event that the
date of the mailing of the notice for the 2006 annual meeting is advanced or
delayed by more than thirty (30) days from the anniversary date of the mailing
of the notice for this year's annual meeting, notice by a shareholder to be
timely must be so delivered not earlier than the close of business on the 120th
day prior to the date of mailing of the notice for the 2006 annual meeting and
not later than the close of business on the later of the 90th day prior to the
date of mailing of the notice for the 2006 annual meeting or the 10th day
following the day on which public announcement of the date of mailing of the
notice for the 2006 meeting is first made by the fund.

     The submission by a shareholder of a proposal for inclusion in a proxy
statement does not guarantee that it will be included. Each fund currently
expects to hold the next annual shareholders' meeting on or about August 15,
2006, which date is subject to change. Shareholder proposals are subject to
certain regulations under the federal securities laws.

Proxies, quorum and voting at the meeting

     Any shareholder who has given his or her proxy to someone has the power to
revoke that proxy at any time prior to its exercise by executing a superseding
proxy or by submitting a notice of revocation to the secretary of the fund. In
addition, although mere attendance at the meeting will not revoke a proxy, a
shareholder present at the meeting may withdraw his or her proxy and vote in
person. All properly executed and unrevoked proxies received in time for the
meeting will be voted in accordance with the instructions contained in the
proxies. If no instruction is given, the persons named as proxies will vote the
shares represented thereby in favor of the nominees in Proposal No. 1, as
described above, and will use their best judgment in connection with the
transaction of such other business as may properly come before the meeting or
any adjournment thereof.


                                       28


     For each fund, one-third of the outstanding shares of each series or
class, or one-third of the outstanding shares of the Trust, entitled to vote,
present in person or represented by proxy, constitutes a quorum for the
transaction of business at the meeting with respect to such series or class, or
with respect to the entire fund, respectively. In the event that at the time
any session of the meeting is called to order a quorum is not present in person
or by proxy, the persons named as proxies may vote those proxies that have been
received to adjourn the shareholder meeting to a later date. In the event that
a quorum is present but sufficient votes in favor of the proposal have not been
received, the persons named as proxies may propose one or more adjournments of
the shareholder meeting to permit further solicitation of proxies with respect
to such proposal. Any such adjournment will require the affirmative vote of
more than one half of the shares of the fund present in person or by proxy at
the session of the meeting to be adjourned. The persons named as proxies will
vote those proxies which they are entitled to vote in favor of any such
proposal in favor of such an adjournment and will vote those proxies required
to be voted against any such proposal against any such adjournment. A
shareholder vote may be taken on one or more of the proposals in the proxy
statement prior to such adjournment if sufficient votes for its approval have
been received and it is otherwise appropriate. Such vote will be considered
final regardless of whether the meeting is adjourned to permit additional
solicitation with respect to any other proposal.

     Shares of the fund represented in person or by proxy, including shares
that abstain or do not vote with respect to a proposal, will be counted for
purposes of determining whether there is a quorum at the meeting. However, an
abstention from voting has the same effect as a vote against a proposal.
Similarly, if a broker or nominee holding shares in "street name" indicates on
the proxy card that it does not have discretionary authority to vote on a
proposal and has not received instructions from the beneficial owner, those
shares will not be considered present and entitled to vote on that proposal.
Thus, a "broker non-vote" has no effect on the voting.

Other business

     While the meeting has been called to transact any business that may
properly come before it, the only matters that the Trustees intend to present
are those matters stated in the attached notice of annual meeting of
shareholders. However, if any additional matters properly come before the
meeting, and on all matters incidental to the conduct of the meeting, it is the
intention of the persons named in the enclosed proxy to vote the proxy in
accordance with their judgment on such matters unless instructed to the
contrary.

Method of solicitation and expenses

     The cost of preparing, assembling and mailing this proxy statement and the
attached notice of annual meeting of shareholders and the accompanying proxy
card for each fund will be borne by that fund. In addition to soliciting
proxies by mail, Pioneer may, at the fund's expense, have one or more of the
fund's officers, representatives or compensated third-party agents, including
Pioneer, PIMSS and PFD, aid in the solicitation of proxies by personal
interview or telephone and telegraph and may request brokerage houses and other
custodians, nominees and fiduciaries to forward proxy soliciting material to
the beneficial owners of the shares held of record by such persons.


                                       29


     Each fund may also arrange to have votes recorded by telephone, the
internet or other electronic means. The voting procedures used in connection
with such voting methods are designed to authenticate shareholders' identities,
to allow shareholders to authorize the voting of their shares in accordance
with their instructions and to confirm that their instructions have been
properly recorded. If these procedures were subject to a successful legal
challenge, such votes would not be counted at the shareholder meeting. Each
fund is unaware of any such challenge at this time. In the case of telephone
voting, shareholders would be called at the phone number the sub-transfer
agent, Mellon Investor Services LLC, has in its records for their accounts, and
would be asked for their Social Security number or other identifying
information. The shareholders would then be given an opportunity to authorize
proxies to vote their shares at the meeting in accordance with their
instructions. In the case of automated telephone and internet voting,
shareholders would be required to provide their Social Security number or other
identifying information and would receive a confirmation of their instructions.

     Persons holding shares as nominees will be reimbursed by Pioneer, upon
request, for the reasonable expenses of mailing soliciting materials to the
principals of the accounts.

                     Appendix A -- Audit Committee Charter

                         EXCHANGE LISTED PIONEER FUNDS

                            Audit Committee Charter

     This Audit Committee Charter is applicable to each of the Pioneer Funds
that are listed on the New York Stock Exchange ("NYSE").

     Italicized terms used in this Charter are defined in Annex A.

     Membership. The Audit Committee shall be composed exclusively of Trustees
("Independent Trustees") who are not "interested persons" as defined in the
Investment Company Act of 1940, as amended, of Pioneer Investment Management,
Inc ("Pioneer"). The Audit Committee shall include at least three Independent
Trustees who are designated for membership from time to time by the Board of
Trustees. In selecting Independent Trustees to serve on the Audit Committee,
the Board of Trustees shall select members who are free of any relationship
that, in the opinion of the Board of Trustees, may interfere, or give the
appearance of interfering, with such member's individual exercise of
independent judgment. Unless otherwise determined by the Board, no member of
the Audit Committee may serve on the audit committee of more than two other
public companies (other than another Pioneer Fund). Except as otherwise
permitted by the applicable rules of the New York Stock Exchange, each member
of the Audit Committee shall be independent. Each member of the Audit Committee
must be financially literate, as such qualification is interpreted by the Board
of Trustees in its business judgment. At least one member of the Audit
Committee shall be an Audit Committee Financial Expert.

     Function. The Audit Committee's purpose is to:

     o    assist the Board of Trustee's oversight of (1) the integrity of the
          Pioneer Funds' financial statements, (2) the Pioneer Funds' compliance
          with legal and regulatory requirements that relates to the Funds'
          accounting and financial reporting, internal financial controls and
          independent audit (except to the extent such responsibility is
          delegated to another committee of the Board of Trustees), (3) the
          independent auditor's qualifications and independence, and (4) the
          performance of the Pioneer Funds' internal audit function and
          independent accountants; and

     o    prepare an Audit Committee Report to the extent required by the
          Securities and Exchange Commission ("SEC") to be included in a Pioneer
          Funds' annual proxy statement or other filing.

     The Audit Committee shall discharge its responsibilities, and shall access
the information provided by the Pioneer Funds' officers, Pioneer and
independent auditors, in accordance with its business judgment.

     Oversight Role. Oversight is the primary role of the Audit Committee.
Pioneer (or in the case of certain Pioneer Funds, Princeton Administrators LLC)
is responsible for maintaining appropriate systems for accounting and internal
controls and preparing the Pioneer Funds' financial statements. The independent
auditors are responsible for auditing


                                      A-1


the Pioneer Funds' financial statements and, to the extent directed by the
Audit Committee, for reviewing the Pioneer Funds' unaudited interim financial
statements. The Audit Committee and the Board of Trustees recognize that the
Funds' officers, Pioneer and the independent auditors have more experience,
expertise, resources and time, and more detailed knowledge and information
regarding the Pioneer Funds' accounting, auditing, internal control and
financial reporting practices than the Audit Committee does. Accordingly, the
Audit Committee's oversight role is not intended to provide any expert or
special assurance as to the financial statements and other financial
information provided by a Pioneer Fund to its shareholders and others. The
authority and responsibilities set forth in this Charter do not reflect or
create any duty or obligation of the Audit Committee to plan or conduct any
audit, to determine or certify that any Pioneer Fund's financial statements are
complete, accurate, fairly presented, or in accordance with generally accepted
accounting principles or applicable law, or to guarantee any independent
auditor's report.

     The independent auditors shall report directly to the Audit Committee, and
the Audit Committee shall be directly responsible for oversight of the work of
the independent auditors, including resolution of disagreements between any
Pioneer Fund's officer, Pioneer and the independent auditors regarding
financial reporting.

     Specific Responsibilities. The specific responsibilities of the Audit
Committee are:

     1.   To act as a liaison between the Pioneer Funds' independent auditors
          and the Board of Trustees of the Pioneer Funds.

     2.   To approve, and in addition recommend to the Board of Trustees for its
          ratification and approval in accord with applicable law, the
          selection, appointment, retention and compensation of an independent
          auditor for each Pioneer Fund prior to the engagement of such
          independent auditor. The Audit Committee should meet with the
          independent auditor prior to the audit to discuss the planning and
          staffing of the audit.

     3.   To meet with independent auditors, including private meetings, and, as
          necessary, Pioneer's internal auditors and the Funds' officers (i) to
          review the arrangements for and scope of the annual audit and any
          special audits; (ii) to discuss the form and substance of the Pioneer
          Funds' financial statements and reports, and any matters of concern
          relating to the Pioneer Funds' financial statements, including any
          adjustments to such statements recommended by the independent
          accountants, or other results of an audit; (iii) to consider the
          independent accountants' comments with respect to the Pioneer Funds'
          financial policies, procedures and internal accounting controls and
          management's responses thereto; (iv) to discuss the Funds' policies
          with respect to risk assessment and risk management; (v) to review the
          resolution of any disagreements between the independent auditors and
          Pioneer regarding the Pioneer Funds' financial reporting; and (vi) to
          review the form of opinion the independent accountants propose to
          render to the Board of Trustees and shareholders.


                                      A-2


     4.   Together with the Independent Trustees Committee, to review and assess
          the renewal materials of all related party contracts and agreements,
          including management advisory agreements, underwriting contracts,
          administration agreements, distribution contracts, and transfer agency
          contracts.

     5.   To monitor the independent auditor of each Pioneer Fund to attempt to
          identify: conflicts of interest between the Pioneer Funds and the
          independent auditor as a result of employment relationships; the
          provision of prohibited non-audit services to a Pioneer Fund by its
          independent auditor; violations of audit partner rotation
          requirements; and prohibited independent auditor compensation
          arrangements whereby individuals employed by the auditor are
          compensated based on selling non-audit services to the fund. The
          independent auditors should promptly contact the Audit Committee or
          its Chair about any significant issue or disagreement concerning a
          fund's accounting practices or financial statements that is not
          resolved to their satisfaction or if Section 10A(b) of the Exchange
          Act has been implicated.

     6.   To ensure that the independent auditors inform the Audit Committee on
          a periodic basis of all relationships between the auditors and
          Pioneer; to engage in a dialogue with the independent auditors with
          respect to any disclosed relationships or services that may impact the
          objectivity and independence of the independent auditors; and to
          recommend that the Board of Trustees take appropriate action in
          response to the independent auditors' report to satisfy itself of the
          independent auditors' independence.

     7.   To pre-approve all audit and non-audit services provided to each
          Pioneer Fund by its independent auditor, directly or pursuant to the
          pre-approval polices attached hereto as Annex B. To pre-approve,
          directly or pursuant to the pre-approval polices attached hereto as
          Annex B, all non-audit services provided by the Pioneer Fund's
          independent auditor to Pioneer and any entity controlling, controlled
          by, or under common control with Pioneer that provides ongoing
          services to a Pioneer Fund, if the engagement relates directly to the
          operations and financial reporting of the Pioneer Fund. The Audit
          Committee is authorized to further delegate, to the extent permitted
          by law, pre-approval responsibilities to one or more members of the
          Audit Committee who shall report to the Audit Committee regarding
          approved services at the Audit Committee's next regularly scheduled
          meeting.

     8.   With respect to any Pioneer Fund listed on the NYSE, to consider
          whether the Audit Committee will recommend to the Board of Trustees
          that the audited financial statements be included in the Fund's annual
          report. The Board of Trustees delegates to the Audit Committee the
          authority to release the Funds' financial statements for publication
          in the annual report, subject to the Board of Trustees' right to

                            identify which directors are independent and
                            disclose the basis for that determination.

                     (b)    In addition, a director is not independent if:

                                   last three years, more than $100,000 in
                                   direct compensation from the listed company,

                                   compensation is not contingent in any way on
                                   continued service).

                            companies, those companies may designate one audit
                            committee for both companies so long as each member
                            of the audit committee is a member of the board of
                            directors of at least one of such dual holding

      Annex B -- Approval of Audit, Audit-Related, Tax and Other Services
                      Provided by the Independent Auditor

Section I -- Policy Purpose and Applicability

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

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

     Approval of a service in accordance with these 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  Annual de minimus approval for audit related, tax and other services with
      an aggregate value up to 20% of the audit and tax fees for the Pioneer
      Funds for such year.

   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.

                                    Annex C

          Policy for Raising and Investigating Complaints or Concerns
                     About Accounting or Auditing Matters

     As contemplated by the Audit Committee Charter, the Audit Committee of the
Pioneer Funds' Board of Trustees has established the following procedures for:

         the confidential, anonymous submission by employees of the Pioneer
         Investment Management, Inc., its parent and affiliates ("collectively,
         Pioneer"), as well as employees of the Funds' various service
         providers, of concerns regarding improprieties or questionable
         practices in Fund accounting or auditing matters, and

         the receipt, retention and treatment of such concerns and complaints.

     Some specific examples of practices that should be reported, if not
adequately addressed by an officer of the Funds, include: uncorrected, material
portfolio pricing errors; failure to follow valuation policies that results in
a material impact on a Fund's net value; failure to correctly impose a sales
charge; material deficiencies in record keeping, processing or reporting of a
Fund's assets and liabilities; fraud involving a Fund's or a service provider's
employees; deficiencies in the design or operation of internal controls what
could adversely affect the Fund's or a service provider's ability to accurately
process and report financial data concerning the Fund; a false or misleading
statement or omission in connection with an audit of a Fund or preparation of
any document in connection with a filing to the SEC or a failure to make a
required disclosure to the Audit Committee; or, any situation that, if
uncorrected, would prevent a Fund from qualifying as a regulated investment
company under the Internal Revenue Code.

Policy Objective

     The objective of this policy is to provide a mechanism by which complaints
and concerns regarding accounting, internal accounting controls or auditing
matters may be raised and addressed without the fear or threat of retaliation.
The Pioneer Funds desire and expect that the employees and officers of Pioneer,
as well as other service providers to the Funds, will report any complaints or
concerns they may have regarding accounting, internal accounting controls or
auditing matters.

Procedures for Raising Complaints and Concerns

     Employees of Pioneer or of service providers to the Funds, as well as any
other person with concerns or complaints regarding accounting, internal
accounting controls or auditing matters, may submit them, in name or
anonymously, in writing to the attention of Pioneer's Director of Internal
Audit, at Pioneer's principal executive offices in Boston. Alternatively, such
concerns or complaints may be communicated, in name or anonymously, directly to
any member of the Funds' Audit Committee.

Procedures for Investigating and Resolving Complaints and Concerns

     All complaints and concerns received by the Director of Internal Audit
shall be promptly forwarded to the Audit Committee of the Fund's Board or to
the Chair of the Audit Committee. If sent only to the Chair, the Chair may
determine whether to refer the issues


                                      A-18


to the entire Audit Committee. The Director will retain and forward to the
Audit Committee a record of all complaints and concerns received (whether or
not determined to have merit) in each fiscal quarter.

     The Audit Committee will evaluate all complaints or concerns received. If
the Audit Committee requires additional information to evaluate a complaint or
concern, it may conduct an investigation, including interviews of persons
believed to have relevant information, or may, in its discretion, authorize
another person or entity to investigate on its behalf.

     After its evaluation of the complaint or concern, the Audit Committee will
recommend to the Funds such action, if any, as it deems necessary and
appropriate to address the substance of the complaint or concern. The Funds
reserve the right to take whatever action the Audit Committee has deemed
appropriate, up to and including a request that Pioneer discharge any employee
deemed to have engaged in improper conduct.

     Whether a complaint or concern is submitted anonymously, the Audit
Committee will strive to keep all complaints and concerns, as well as the
identity of those who submit them or who participate in any investigation,
confidential, and to limit disclosure to those with a business need to know.

Retaliation Is Prohibited

     Pioneer shall not penalize or retaliate against any person or entity for
reporting a complaint or concern, unless it is determined by the Director of
Internal Audit or the Audit Committee that the complaint or concern was raised
with knowledge that it was false. Retaliation against any person or entity for
submitting, or for cooperating in the investigation of, a complaint or concern
will not be tolerated by Pioneer or the Funds, and will warrant disciplinary
action against the offending party, up to and including termination of
employment. In addition, retaliation is unlawful, and may result in criminal
action.

     Pioneer will distribute this policy to all employees, and will arrange for
its distribution to all Fund service providers.

     The Pioneer Funds shall retain records of all complaints and concerns
received by them, and a record of their disposition, for a minimum of five
years from the date of the report.
