This proxy statement is being used by the board of trustees of each fund to

fund. Each fund's special meeting will be held at the same time at the
offices of Hale and Dorr LLP, 60 State Street, 26th Floor, Boston,

WHO IS ELIGIBLE TO VOTE

Shareholders of record of a fund as of the close of business on February
14, 2003 (the "record date") are entitled to vote on all of that fund's
business at the special shareholder meeting and any adjournments thereof.
Each share is entitled to one vote. Shares represented by properly executed

to shareholders' instructions. If any other business comes before the
special shareholder meeting, your shares will be voted at the discretion of
the persons named as proxies. 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 listed in Proposal 1 and in favor of each of the other proposals.

PROPOSAL 1

ELECTION OF BOARD OF TRUSTEES

Shareholders of each fund are being asked to consider the election of eight
nominees to the board of trustees of the fund. All of the nominees for
election to a fund's board currently serve as trustees for that fund and
have served in that capacity continuously since originally elected or
appointed. Each trustee will be elected to hold office until the next
meeting of shareholders 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 following table sets forth each nominee's position(s) with the funds,
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 the 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 the fund are referred to as
Independent Trustees. Each of the trustees serves as a trustee of each of
the 50 U.S. registered investment portfolios for which Pioneer serves as
investment adviser (the "Pioneer Funds"). The address of all Interested
Trustees is 60 State Street, Boston, Massachusetts 02109.

The board of trustees has adopted a charter for the Audit Committee, which
is attached as Exhibit A to this proxy statement. In accordance with its
charter, the purposes of the Audit Committee are to:

  * act as a liaison between the fund's independent auditors and the full
    board of trustees of the fund;

  * discuss with the fund's independent auditors their judgments about the
    quality of the fund's accounting principles and underlying estimates as
    applied in the fund's financial reporting;

  * 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;

  * review and assess from time to time, as it deems necessary and
    appropriate:

  * brokerage and soft dollar arrangements of the fund,

  * the utilization of any line of credit, and

  * "as of" gain/loss activity of the fund;

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

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

  * receive on a periodic basis a formal written statement delineating all
    relationships between the auditors and the fund or Pioneer; to actively
    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
    trustees take appropriate action in response to the independent auditors'
    report to satisfy itself of the independent auditors' 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 auditors the matters relating to the quality of each fund's
financial reporting; and (3) received written disclosures and an
independence letter from the independent public accountants and discussed
with the independent accountants that firm's independence. Based upon the
review and discussions referred to above, the audited financial statements
were included in the annual report for each fund's most recently completed
fiscal year for filing with the Securities and Exchange Commission (SEC).

The Audit Committee is comprised of Ms. Piret (chairperson), Ms. Bush
(since December 2002), Dr. Egdahl (since December 2002), Ms. Graham (since
December 2002), Mr. West and Mr. Winthrop.

The Nominating Committee reviews the qualifications of any candidate
recommended by the Independent Trustees to serve as an Independent Trustee
and makes a recommendation regarding that person's qualifications to the
Independent Trustees and the full board of trustees. The Nominating
Committee will also consider nominees recommended by shareholders to serve
as trustees provided that shareholders submitting such recommendations
comply with all relevant provisions of Rule 14a-8 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act").

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

The Independent Trustees Committee reviews the funds' management contracts
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.

During the most recently completed fiscal year, the board of trustees held
8 meetings. All of the current trustees and committee members then serving
attended at least 75% of those meetings of the board of trustees and
applicable committees, if any, held during the applicable fiscal year.

The following table indicates the value of shares that each trustee
beneficially owned in each fund and Pioneer Funds in the aggregate as of
December 31, 2002. Beneficial ownership is determined in accordance with
SEC rules. The share value of any closed-end fund is based on its closing
market price on December 31, 2002. The share value of any open-end Pioneer
Fund is based on the net asset value of the class of shares on December 31,
2002. The dollar ranges in this table are in accordance with SEC
requirements.

PROPOSAL 2

APPROVAL OF A NEW MANAGEMENT CONTRACT

Summary

Pioneer has served as each fund's investment adviser since its inception,
except for Pioneer Growth Shares for which Pioneer has served as investment
adviser since 1993. Pioneer serves as the investment adviser for the
Pioneer Family of Funds and for other institutional accounts. Pioneer, a
registered investment adviser under the Investment Advisers Act of 1940, as
amended, is an indirect, wholly owned subsidiary of UniCredito Italiano.
Pioneer is located at 60 State Street, Boston, Massachusetts 02109.

At a meeting of the board of trustees held on December 3, 2002, the
trustees, including all of the Independent Trustees, present at such
meeting unanimously approved and voted to recommend that the shareholders
of each fund approve a proposal to adopt a new management contract with
Pioneer (the "proposed contract"). Each fund's existing management contract
with Pioneer (the "existing contract") and the proposed contract also is
referred to below as a "contract." The primary change in each proposed
contract is the substitution of a different benchmark for the fund's
performance fee adjustment (the "Benchmark Index") as follows:


                        Current Benchmark       Substitute Benchmark
Fund                    Index                   Index                   Reason(s) for Change

                                                                        investment approach


Because of the reasons discussed in this proxy statement, the board of
trustees of each fund concluded that changing the fund's Benchmark Index is
in the best interests of its shareholders. The proposed contract also would
modify certain other provisions of the existing contract relating to fund
expenses as discussed below. The current Benchmark Indexes are referred to
as the S&P 400, Lipper Growth and Income Index, Lipper Growth Index, Lipper
Growth and Income Index and the Russell 1000, respectively. The proposed
Benchmark Indexes are referred to as the Russell Midcap Growth Index,
Russell 1000 Value Index, Russell Midcap Value Index, S&P 500 and the
Russell 1000 Growth Index, respectively.

Each proposed contract would not change the basic structure of the fund's
management fee, the base management fee or the maximum positive or negative
performance adjustment. The management fee is calculated based on two
components: a "basic fee" and a "performance adjustment." The basic fee is
charged at the annual rate of the fund's average daily net assets set forth
in the table below. No change in the basic fee is proposed. The basic fee
is then adjusted up or down based upon the return of the fund's Class A
shares relative to the performance of the Benchmark Index. The performance
comparison is made based upon a rolling three-year period. For each
percentage point by which the fund's performance exceeds (is less than) the
performance of the Benchmark Index, the basic management fee is increased
(decreased) by 0.01% (0.02% in the case of Pioneer Mid Cap Growth Fund).
The most the basic fee can be adjusted is plus or minus 0.10% (0.20% in the
case of Pioneer Mid Cap Growth Fund). The resulting maximum management fee
and minimum management fee, in each case on an annual basis, are also
indicated in the table below:


                                                                   Performance

Pioneer Mid Cap Growth Fund. The fund's current Benchmark Index -- the S&P
400 -- no longer is closely aligned with the fund's investment approach.
Until 2001, the fund was managed as a "core" mid cap fund. That means that
the securities in the fund's portfolio had a market capitalization that was
mid cap and a balance between issuers considered value and growth. In 2001,
the fund was repositioned as a mid cap growth fund and its portfolio is now
primarily composed of issuers selected on the basis of their growth
potential. In light of this change in the fund's investment focus, the
board of trustees concluded that it was desirable to change the Benchmark
Index so the Benchmark Index is aligned with the manner in which the fund
is managed. In light of the objectives of the fund's performance fee
structure, the board of trustees considered several alternative successor
Benchmark Indexes and concluded that the Russell Midcap Growth Index was
best suited to achieve these goals. The board of trustees believes that the
modified performance adjustment will better align the interests of the
fund's shareholders and Pioneer. Specifically, Pioneer recommended this
change -- and the trustees determined to recommend the change to
shareholders -- based on the following:

  * Performance-based compensation continues to be a desirable method to
    reward good investment performance and penalize bad performance.

  * The fund is managed as a mid cap growth fund. The Russell Midcap Growth
    Index represents a portfolio with a similar focus, while the S&P 400 is a
    mid cap index comprised of stocks that are not chosen on the basis of a
    growth or value investment approach. Since the objective of a
    performance-based fee is to align the economic incentives of the
    management firm with the interests of shareholders, the trustees
    determined that basing the performance adjustment on the Russell Midcap
    Growth Index would better align Pioneer's economic incentives with the
    manner in which the fund is managed and consequently the economic interest
    of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals involved in the management of Pioneer Mid Cap Growth Fund in
    part upon the relative performance of the fund and the Russell Midcap
    Growth Index. This will similarly align the financial interests of the
    portfolio managers with those of the fund and Pioneer.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Mid-Cap Growth Index, and concluded that
    the alternative indexes would not be as effective in achieving the goals
    of the performance fee.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the Russell Midcap Growth Index as the
    Benchmark Index since the adoption of a performance-based fee in 1996.
    While the results in individual years vary, overall the use of the Russell
    Midcap Growth Index would have resulted in a higher net management fee for
    Pioneer than the actual fee that Pioneer received. However, the Russell
    Midcap Growth Index would have resulted in a lower fee than a peer group
    index. As a result of the change in the Benchmark Index, the fund's annual
    operating expenses may increase. Whether any increase will occur compared
    to the continued use of the current Benchmark Index will depend upon the
    fund's relative performance to the current and new benchmarks, which
    cannot be predicted.

  * The Russell Midcap Growth Index is widely recognized and widely used by
    mutual fund and other institutional investment managers as a benchmark of
    U.S. equity performance. It is published daily in most newspapers that
    carry stock market information. This historical comparison is not
    necessarily indicative of the relative fees that would result from future
    performance.

Pioneer Value Fund and Pioneer Mid Cap Value Fund. The funds' current
Benchmark Indexes -- the Lipper Growth and Income Index and the Lipper
Growth Index, respectively -- are no longer widely available. The board of
trustees concluded that it was desirable to have a Benchmark Index that (i)
is readily available to shareholders in order that the shareholders are in
a better position to evaluate the fund's performance and (ii) is aligned
with the manner in which the fund is managed and the basis upon which
Pioneer provides incentive compensation to its portfolio managers. In light
of the objectives of the funds' performance fee structure, the board of
trustees considered several alternative successor Benchmark Indexes and
concluded that the Russell 1000 Value Index (for Pioneer Value Fund) and
the Russell Midcap Value Index (for Pioneer Mid Cap Value Fund) were best
suited to achieve these goals. The board of trustees believes that the
modified performance adjustment will better align the interests of each
fund's shareholders and Pioneer. Specifically, Pioneer recommended this
change -- and the trustees determined to recommend the change to
shareholders -- based on the following:

  * Performance-based compensation continues to be a desirable method to
    reward good investment performance and penalize bad performance.

  * The Lipper Growth and Income Index and the Lipper Growth Index are no
    longer widely available. The Russell indexes are widely recognized and
    widely used by mutual fund and other institutional investment managers as
    benchmarks of U.S. equity performance. They are published daily in most
    newspapers that carry stock market information.

  * Each fund is managed as a value fund, meaning that Pioneer seeks
    securities for the fund's portfolio that are reasonably priced or selling
    at substantial discounts to their underlying values. The Russell 1000
    Value Index and the Russell Midcap Value Index represent portfolios with
    similar focuses, i.e., portfolios of value-oriented stocks. Since the
    objective of a performance-based fee is to align the economic incentives
    of the management firm with the interests of shareholders, the trustees
    determined that basing the performance adjustments on the Russell 1000
    Value Index and the Russell Midcap Value Index would better align
    Pioneer's economic incentives with the manner in which the funds are
    managed and consequently the economic interest of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of these funds in part upon the
    relative performance of Pioneer Value Fund and the Russell 1000 Value
    Index and upon the relative performance of Pioneer Mid Cap Value Fund and
    the Russell Midcap Value Index. This will similarly align the financial
    interests of the portfolio managers with those of the fund and Pioneer.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Large Cap Value Index and the Lipper
    Mid-Cap Value Index, respectively, and concluded that the alternative
    indexes would not be as effective in achieving the goal of the performance
    fee.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by each fund using the applicable Russell index as the Benchmark
    Index since the fund's adoption of a performance-based fee. While the
    results in individual years vary, overall the use of the Russell index
    would have resulted in a lower management fee for Pioneer from Pioneer
    Value Fund than the actual fee that Pioneer received or the fee that would
    have resulted using alternative peer group indexes. In the case of Pioneer
    Mid Cap Value Fund, the use of the Russell Midcap Value Index would have
    resulted in a higher management fee for Pioneer than either the actual fee
    Pioneer received or the fee that would have resulted using an alternative
    peer group index. However, the board of trustees concluded that the
    benefits of a change in the Benchmark Index outweighed this potentially
    negative factor. This historical comparison is not necessarily indicative
    of the relative fees that would result from future performance. As a
    result of the change in the Benchmark Index, the fund's annual operating
    expenses may increase. Whether any increase will occur compared to the
    continued use of the current Benchmark Index will depend upon the fund's
    relative performance to the current and new benchmarks, which cannot be
    predicted.

Pioneer Fund. The fund's current Benchmark Index -- the Lipper Growth and
Income Index -- is no longer widely available. The board of trustees
concluded that it was desirable to have a Benchmark Index that (i) is
readily available to shareholders in order that the shareholders are in a
better position to evaluate the fund's performance and (ii) is aligned with
the manner in which the fund is managed and the basis upon which Pioneer
provides incentive compensation to its portfolio managers. In light of
these objectives, the board of trustees considered several alternative
successor Benchmark Indexes and concluded that the S&P 500 was best suited
to achieve these goals. The board of trustees believes that the modified
performance adjustment will better align the interests of the fund's
shareholders and Pioneer. Specifically, Pioneer recommended this change --
and the trustees determined to recommend the change to shareholders -- based
on the following:

  * Performance-based compensation continues to be a desirable method to
    reward good investment performance and penalize bad performance.

  * The Lipper Growth and Income Index is no longer widely available. The S&P
    500 is widely recognized and widely used by mutual fund and other
    institutional investment managers as a benchmark of U.S. equity
    performance. It is published daily in most newspapers that carry stock
    market information.

  * The fund is managed as a large cap/core fund, meaning that the fund
    primarily invests in large capitalization issuers with a balance between
    value and growth stocks. The S&P 500 represents a portfolio with a similar
    focus. The objective of a performance-based fee is to better align the
    economic incentives of the management firm with the interests of
    shareholders. Basing the performance adjustment on the S&P 500 would align
    Pioneer's economic incentives with the economic interest of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of Pioneer Fund in part upon the
    relative performance of the fund and the S&P 500. This will similarly
    align the financial interests of the portfolio managers with those of the
    fund and Pioneer.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Large Cap Value Index and the Lipper
    Large Cap Core Index, and concluded that the alternative indexes would not
    be as effective in achieving the goal of the performance fee.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the S&P 500 as the Benchmark Index since the
    adoption of a performance-based fee in 1996. While the results in
    individual years vary, overall the use of the S&P 500 would have resulted
    in a lower management fee for Pioneer than the actual fee that Pioneer
    received or the fee that would have resulted using alternative peer group
    indexes. This historical comparison is not necessarily indicative of the
    relative fees that would result from future performance. As a result of
    the change in the Benchmark Index, the fund's annual operating expenses
    may increase. Whether any increase will occur compared to the continued
    use of the current Benchmark Index will depend upon the fund's relative
    performance to the current and new benchmarks, which cannot be predicted.

Pioneer Growth Shares. The fund's current Benchmark Index -- the Russell
1000 -- is less closely aligned with the fund's investment approach than the
proposed Benchmark Index, the Russell 1000 Growth Index. The fund is
managed as a large cap growth fund, and Pioneer seeks securities of issuers
with above average potential for earnings and revenue growth for the fund's
portfolio. The Russell 1000 includes stocks with both value and growth
characteristics, while the Russell 1000 Growth Index represents the
securities in the Russell 1000 with growth characteristics. In light of the
fund's investment focus, the board of trustees concluded that it was
desirable to change the Benchmark Index so the Benchmark Index is aligned
with the manner in which the fund is managed. In light of the objectives of
the fund's performance fee structure, the board of trustees considered
several alternative successor Benchmark Indexes and concluded that the
Russell 1000 Growth Index was best suited to achieve these goals. The board

  * The fund is managed as a large cap growth fund. The Russell 1000 Growth
    Index represents a portfolio with a similar focus, i.e., a portfolio of
    growth-oriented stocks, while the Russell 1000 is a large cap index
    comprised of stocks that are not chosen on the basis of a growth or value
    investment approach. Since the objective of a performance-based fee is to
    align the economic incentives of the management firm with the interests of
    shareholders, the trustees determined that basing the performance
    adjustment on the Russell 1000 Growth Index would better align Pioneer's
    economic incentives with the manner in which the fund is managed and
    consequently the economic interest of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of Pioneer Growth Shares in part
    upon the relative performance of the fund and the Russell 1000 Growth
    Index. Basing the performance adjustment on the Russell 1000 Growth Index
    would align Pioneer's economic incentives with the economic interest of
    shareholders.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Large-Cap Growth Index, and concluded
    that the alternative indexes would not be as effective in achieving the
    goals of the performance fee.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the Russell 1000 Growth Index as the Benchmark
    Index since the adoption of a performance-based fee in 1999. While the
    results in individual years vary, overall the use of the Russell 1000
    Growth Index would have resulted in a higher net management fee for
    Pioneer than the actual fee that Pioneer received. However, the board of
    trustees concluded that the potential benefits of the proposed Benchmark
    Fee outweighed this potentially negative factor. This historical
    comparison is not necessarily indicative of the relative fees that would
    result from future performance. As a result of the change in the Benchmark
    Index, the fund's annual operating expenses may increase. Whether any
    increase will occur compared to the continued use of the current Benchmark
    Index will depend upon the fund's relative performance to the current and
    new benchmarks, which cannot be predicted.

  * The Russell 1000 Growth Index is widely recognized and widely used by
    mutual fund and other institutional investment managers as a benchmark of
    U.S. equity performance. It is published daily in most newspapers that
    carry stock market information.

Terms of existing and proposed contracts

Except for the modification of the Benchmark Index and modification to the
expense provision discussed below, the terms of the existing and proposed
contracts are substantially identical. Pursuant to the terms of each
contract, Pioneer serves as investment adviser to each fund and is
responsible for the overall management of each fund's business affairs
subject only to the authority of the board of trustees. Pioneer is
authorized to buy and sell securities for the account of the fund and to
designate brokers to carry out such transactions. Pioneer may not make any
purchase the cost of which exceeds funds currently available for the fund
and may not make any purchase which would violate any fundamental policy or
restriction in the fund's prospectus or statement of additional information
as in effect from time to time.

Existing contracts

The shareholders of each fund last approved the fund's existing contract on
September 11, 2000. Each existing contract was approved by the board of
trustees, with its renewal most recently approved at a meeting held on
December 3, 2002, at which meeting the board of trustees also approved the
proposed contract, subject to shareholder approval. Each existing contract
is renewable annually by the vote of a majority of the fund's board,
including a majority of the trustees who are not "interested persons" (as
defined in the 1940 Act) of the fund, Pioneer or PFD, cast in person at a
meeting called for the purpose of voting on such renewal. Each existing
contract terminates if assigned (as defined in the 1940 Act) and may be
terminated without penalty by either party by vote of its board or a
majority of the fund's outstanding voting securities and upon 60 days'
written notice.

As compensation for its management services and certain expenses which
Pioneer incurs on behalf of the fund, the fund pays Pioneer an annual
management fee. The basic fee is equal to the percentage(s) stated in the
table above that is applied to the fund's average daily net assets on an
annual basis. A percentage of the basic fee rate (based upon the number of
days in the current month) is multiplied by the fund's average daily net
assets for the current month, giving a dollar amount that is the monthly
basic fee. The basic fee is subject to an upward or downward adjustment
depending on whether and to what extent the investment performance of the
fund for the performance period exceeds, or is exceeded by, the record of
the Benchmark Index over the same period.

The performance period consists of the current month and the prior 35
months. Each percentage point of difference (up to a maximum of +/-10
(+/-20 in the case of Pioneer Mid Cap Growth Fund)) is multiplied by a
performance adjustment rate of 0.01% (0.02% in the case of Pioneer Mid
Cap Growth Fund). The maximum annualized adjustment rate is +/-0.10%
(+/-0.20% for Pioneer Mid Cap Growth Fund). This performance comparison
is made at the end of each month. A percentage of this rate (based upon
the number of days in the current month) is then multiplied by the
average daily net assets of the fund over the entire performance period,
giving a dollar amount that is added to (or subtracted from) the basic
fee. The monthly performance adjustment is further adjusted to the
extent necessary in order to ensure that the total annual adjustment to
the basic fee does not exceed +/-0.10% of the average daily net assets
for that year (+/-0.20% for Pioneer Mid Cap Growth Fund). The basic fee
is computed daily, the performance fee adjustment is calculated once per
month and the entire management fee is paid monthly.

Each fund's performance is calculated based on the net asset value of the
fund's Class A shares. For purposes of calculating the performance
adjustment, any dividends or capital gain distributions paid by the fund
are treated as if reinvested in Class A shares at the net asset value as of
the payment date. Because the adjustment to the basic fee is based on the
comparative performance of the fund and the record of the Benchmark Index,
the controlling factor is not whether fund performance is up or down, but
whether it is up or down more or less than the record of the Benchmark
Index. Moreover, the comparative investment performance of the fund is
based solely on the recent performance period without regard to the
cumulative performance over a longer or shorter period of time.

Proposed contracts

The terms of each proposed contract differ materially from those of each
existing contract only in respect of the performance adjustment component
of the management fee payable to Pioneer and the modification of the fund's
expenses discussed below. This summary of the proposed contracts is
qualified by reference to the form of proposed management contract attached
to this proxy statement as Exhibit B.

Index comparisons

Pioneer Mid Cap Growth Fund. In 1996, the trustees initially designated the
S&P 400 as the Benchmark Index for purposes of calculating the performance
adjustment. The S&P 400 is a market capitalization weighted index of 400
domestic stocks chosen for market size (midcap), liquidity and industry
group representation. The Russell Midcap Growth Index is an index comprised
of the issuers included in the Russell Midcap[R] Index with the highest
price-to-book ratios and higher forecast growth rates. The Russell Midcap
Index consists of the 800 issuers in the Russell 1000 with the smallest
market capitalization.

Pioneer Value Fund and Pioneer Mid Cap Value Fund. In the mid- to
late-1990s, the trustees initially designated the Lipper Growth and Income
Index as the Benchmark Index for Pioneer Value Fund and the Lipper Growth
Index for Pioneer Mid Cap Value Fund for purposes of calculating their
performance adjustments. The Lipper Growth and Income Index represents the
arithmetic mean performance (i.e., equally weighted) of the thirty largest
funds with investment objectives oriented toward growth and income. The
Lipper Growth Index also an equally weighted index of the thirty largest
funds, but with investment objectives oriented toward growth. In 1999,
Lipper significantly changed its fund classification system. Previously,
Lipper's classification system had been based on each fund's stated
investment objective. Lipper now bases a fund's classification on the
actual securities in the fund's portfolio and its investment style. As part
of this change, Lipper reclassified funds in several objective categories,
including its Growth and Income category and its Growth category. Lipper
currently classifies Pioneer Value Fund as a "Large-Cap Value" fund and
Pioneer Mid Cap Value Fund as a "Mid-Cap Value" fund. Although Lipper still
calculates the current Benchmark Indexes, they are no longer widely
published. Pioneer and the trustees also do not believe that the investment
companies included in the Lipper Growth and Income Index and the Lipper
Growth Index are representative of the funds' most comparable peers. In
addition, the Lipper Growth and Income Index includes funds that have
designated income as a primary aim. Although Pioneer Value Fund will
continue to consider dividend income in its security selection process,
Pioneer and the trustees are recommending that the fund no longer identify
this consideration in a manner more prominent than its other stock
selection criteria. See Proposal 4(n). The Russell 1000 Value Index is a
measure of the performance of the value-oriented stocks in the Russell
1000. The Russell Midcap Value Index is a measure of the performance of
value-oriented stocks in the Russell Midcap Index.

Pioneer Fund. In 1996, the trustees initially designated the Lipper Growth
and Income Index as the Benchmark Index for purposes of calculating the
performance adjustment. The Lipper Growth and Income Index represents the
arithmetic mean performance (i.e., equally weighted) of the thirty largest
funds with investment objectives oriented toward growth and income. In
1999, Lipper significantly changed its fund classification system.
Previously, Lipper's classification system had been based on each fund's
stated investment objective. Lipper now bases a fund's classification on
the actual securities in the fund's portfolio and its investment style. As
part of this change, Lipper reclassified funds in several objective
categories, including its Growth and Income category. Lipper currently
classifies the fund as a "Large Cap Core" fund. Although Lipper still
calculates the Lipper Growth and Income Index, it is no longer widely
published. Pioneer and the trustees also do not believe that the investment
companies included in the Lipper Growth and Income Index are representative
of the fund's most comparable peers. In addition, the Lipper Growth and
Income Index includes funds that have designated income as a primary aim.
Although the fund will continue to consider dividend income in its security
selection process, Pioneer does not identify this consideration in a manner
more prominent than its other stock selection criteria. The S&P 500 is an
unmanaged capitalization-weighted index designed to measure performance of
the broad domestic economy through changes in the aggregate market value of
500 stocks representing all major industries. Its component stocks are
listed on the New York Stock Exchange, American Stock Exchange and traded
in the over-the-counter market. The S&P 500 consists of 500 stocks chosen
for market size, liquidity, and industry group representation. It is a
market value weighted index (stock price times number of shares
outstanding), with each stock's weight in the S&P 500 proportionate to its
market value. The S&P 500 is one of the most widely used benchmarks of U.S.
equity performance.

Pioneer Growth Shares. In 1999, the trustees initially designated the
Russell 1000 as the Benchmark Index for purposes of calculating the
performance adjustment. The Russell 1000 measures the performance of the
1,000 largest companies in the Russell 3000[R] Index, which represents
approximately 92% of the total market capitalization of the Russell 3000
Index. The Russell 1000 Growth Index measures the performance of those
Russell 1000 companies with higher price-to-book ratios and higher
forecasted growth values. The board of trustees believes that it is
appropriate and in the best interests of the fund's shareholders to change
the Benchmark Index from the Russell 1000 to the Russell 1000 Growth Index.

Implementation of modification to the performance adjustments

The effective date of the proposed contract is expected to be May 1, 2003
or as soon thereafter as practicable. To prevent unfairness to each fund,
the calculation of the performance adjustment for any portion of the
performance period prior to effective date of the change will be based upon
the fund's performance compared to the current Benchmark Index. Because the
performance adjustment is based on a 36-month performance period, the use
of the current Benchmark Index thus will "phase out" over 36 months.

Effect of modifying the performance adjustments

If the proposal is approved, subject to a 36-month "phase-out," each fund's
management fee rate would be increased or decreased based on the fund's
performance relative to the proposed Benchmark Index. The impact of the
change in any Benchmark Index cannot be predicted. The future impact of
changing the Benchmark Index will depend on many different factors and may
represent an increase or decrease from the fund's management fee under the
existing contract, depending on the fund's performance relative to the
current Benchmark Index and the proposed Benchmark Index.

The following table shows for each of the fiscal periods since each fund
implemented a performance fee the actual fee paid by the fund to Pioneer
and Pioneer's estimate of the fee that would have been paid if the proposed
Benchmark Index had been the Benchmark Index throughout the relevant
period.

Examples

The following examples help you compare the costs of investing in each fund
with the cost of investing in other mutual funds. They assume that: a) you
invest $10,000 in the fund for the time periods shown, b) you reinvest all
dividends and distributions, c) your investment has a 5% return each year
and d) the fund's operating expenses remain the same. The tables show your
costs under the current contract and your costs if the proposed contract
had been in effect during a fund's most recent fiscal year.

Modification of operating expense provision

Under each existing contract, Pioneer pays all expenses not specifically
assumed by the fund under the existing contract where such expenses are
incurred by Pioneer or the fund in connection with the management of the
affairs of, and the investment and reinvestment of the assets of, the fund.
Under the existing contracts each fund assumes the following expenses: (a)
charges and expenses for fund accounting, pricing and appraisal services
and related overhead, including, to the extent such services are performed
by personnel of Pioneer or its affiliates, office space and facilities and
personnel compensation, training and benefits; (b) the charges and expenses
of auditors; (c) the charges and expenses of any custodian, transfer agent,
plan agent, dividend disbursing agent and registrar appointed by the fund;
(d) issue and transfer taxes chargeable to the fund in connection with
securities transactions to which the fund is a party; (e) insurance
premiums, interest charges, dues and fees for membership in trade
associations and all taxes and corporate fees payable by the fund to
federal, state or other governmental agencies; (f) fees and expenses
involved in registering and maintaining registrations of the fund and/or
its shares with federal regulatory agencies, state or blue sky securities
agencies and foreign jurisdictions, including the preparation of
prospectuses and statements of additional information for filing with such
regulatory authorities; (g) all expenses of shareholders' and trustees'
meetings and of preparing, printing and distributing prospectuses, notices,
proxy statements and all reports to shareholders and to governmental
agencies; (h) charges and expenses of legal counsel to the fund and the
trustees; (i) any distribution fees paid by the fund in accordance with
Rule 12b-1 under the 1940 Act; (j) compensation of those trustees of the
fund who are not affiliated with or interested persons of Pioneer, the fund
(other than as trustees), PIM-USA or PFD; (k) the cost of preparing and
printing share certificates; and (l) interest on borrowed money, if any. In
addition, the fund pays all brokers' and underwriting commissions
chargeable to the fund in connection with its securities transactions.

The proposed contract would maintain the same basic arrangement with
respect to each fund's expenses. However, a new category of assumed
expenses would be added. This category would include any other expense that
the applicable fund, Pioneer or any other agent of the fund may incur (A)
as a result of a change in the law or regulations, (B) as a result of a
mandate from the board of trustees with associated costs of a character
generally assumed by similarly structured investment companies or (C) that
is similar to the expenses listed in the existing contract. Whether a fund
assumes expenses that fall into this category in the future would be
determined by the board of trustees (including a majority of the
Independent Trustees) and not Pioneer. The intention of this additional
category is to allow the board of trustees some flexibility to allocate to
any fund expenses that may be incurred, and would otherwise be paid by
Pioneer, that arise out of changed circumstances or board mandates or are
of the same character as the expenses currently allocated to the fund.
Since the board of trustees has no current plans to cause the funds to
assume additional expenses pursuant to this new category, adoption of the
proposed contract is not expected to have any immediate effect on a fund's
expenses as a result of this provision. However, this provision may in the
future result in the fund incurring additional expenses, which could
adversely affect the fund's performance.

Other provisions under the existing and proposed contracts

Standard of care. Under each contract, Pioneer "will not be liable for any
error of judgment or mistake of law or for any loss sustained by reason of
the adoption of any investment policy or the purchase, sale or retention of
any security on the recommendation of [Pioneer] . . . ." Pioneer, however,
shall not be protected against liability by reason of its ". . . willful
misfeasance, bad faith or gross negligence in the performance of its duties
or by reason of its reckless disregard of its obligations and duties" under
each contract.

Pioneer's authority. Each contract provides that Pioneer shall have full
discretion to act for the fund in connection with purchase and sale
transactions subject only to the declaration of trust, by-laws, currently
effective registration statements under the 1940 Act and the Securities Act
of 1933, as amended, investment objective, policies and restrictions of the
fund in effect from time to time, and specific policies and instructions
established from time to time by the trustees.

Portfolio trading. Each contract expressly permits Pioneer to engage in
such activity. For a more detailed description of the fund's current
portfolio brokerage practices, see Exhibit C.

Expense limitation. Each contract provides that Pioneer may from time to
time agree not to impose all or a portion of its fee or otherwise take
action to reduce expenses of the fund. Any such fee limitation or expense
reduction is voluntary and may be discontinued or modified by Pioneer at
any time.

Other provisions. Each contract includes provisions that provide that: (i)
the law of The Commonwealth of Massachusetts shall be the governing law of
the contract; (ii) Pioneer is an independent contractor and not an employee
of the fund; (iii) the contract is the entire agreement between the parties
with respect to the matters described therein; (iv) the contract may be
executed using counterpart signature pages; (v) invalid or unenforceable
provisions of the contract are severable and do not render the entire
agreement invalid or unenforceable; and (vi) subject to obtaining best
execution, Pioneer may consider sales of the fund when selecting brokers
and dealers to execute the fund's securities transactions.

Miscellaneous

If approved, the proposed contract will become effective on May 1, 2003 (or
if approved after that date, on the first day of the first month following
the approval date), subject to a 36-month "phase-out" period with respect
to the modification of the performance adjustment (see above), and will
continue in effect until December 31, 2004. Thereafter, the proposed
contract will continue from year to year subject to annual approval by the
board of trustees in the same manner as the existing contract. The proposed
contract terminates if assigned (as defined in the 1940 Act) and may
terminate without penalty by either party, by vote of its board or by a
vote of a majority of the outstanding voting securities of the fund and
upon 60 days' written notice.

Additional information pertaining to Pioneer

affiliations, brokerage policies and certain other matters pertaining to
Pioneer, see Exhibit C.

Factors considered by the trustees

The trustees have been monitoring the continued appropriateness of each
current Benchmark Index for several years and at several meetings during
2002 considered alternative successor indexes to each fund's Benchmark
Index. The trustees also considered the merits of continuing a
performance-based fee structure compared to a traditional asset based fee.
On the basis of that review, the trustees determined that the terms of each
proposed contract are fair and reasonable and that approval of the proposed
contract on behalf of the fund is in the best interests of the fund and its
shareholders. The trustees believe that the proposed contracts will enable
the funds to enjoy high quality investment advisory services at a cost they
deem appropriate, reasonable and in the best interests of the funds and
their shareholders. Each proposed contract also provides Pioneer with an
economic incentive to outperform the Benchmark Index and to devote
sufficient resources to the management of the fund. In making such
determinations, the Independent Trustees met independently from the
Interested Trustees of the funds and any officers of Pioneer or its
affiliates. The Independent Trustees also relied upon the assistance of
counsel to the Independent Trustees and counsel to the funds. In
considering the proposed contract, the trustees did not identify any single
factor as all-important or controlling, and the following summary does not
detail all the matters considered.

In connection with their meeting on December 3, 2002 and at meetings of the
Independent Trustees on November 5, 2002 and November 18, 2002, the
trustees requested and received materials specifically relating to the
proposed changes. These materials included (i) information about the effect
of the changes on each fund's management fee and overall expense ratio,
(ii) comparative information about the composition and use of the current
Benchmark Index, the proposed Benchmark Index and other alternative
indexes; (iii) information regarding the relative historical correlation of
the performance of each fund, the current Benchmark Index and the proposed
Benchmark Index; (iv) information regarding alternative indexes and the
fees that Pioneer would have been paid under certain of these indexes and
(v) detailed rationales for, including potential benefits of, the changes.
The Independent Trustees also consulted with an independent evaluator of
mutual funds as to the appropriateness of each proposed Benchmark Index and
other alternative indexes as a benchmark for the fund's performance in
light of the fund's objective and its investment style, which included a
study of the correlation of the fund's investment performance with the
performance of several securities indexes and an analysis of certain
characteristics of such indexes, including median market capitalization and
sector weighting, with the characteristics of the fund.

In considering and evaluating each proposed contract, the board of trustees
considered the continued appropriateness of a performance-based fee. The
board of trustees concluded that such a fee arrangement continues to be in
the best interest of shareholders and rewards Pioneer if the fund achieves
a performance record superior to the proposed Benchmark Index and penalizes
Pioneer for underperformance. The board also reexamined the appropriateness
of the basic fee and the amount of adjustment to that basic fee that may
result from performance. The board concluded that the basic fee was
appropriate and in line with the asset based fees incurred by similar
funds. The amount of the performance adjustment was also considered to be
reasonable and sufficient to serve its purpose to provide added incentive
to Pioneer to achieve above average performance for the fund.

The board of trustees concluded that it was desirable to have a Benchmark
Index that (i) is readily available to shareholders in order that the
shareholders are in a better position to evaluate the fund's performance
and (ii) is aligned with the manner in which the fund is managed and the
basis upon which Pioneer provides incentive compensation to its portfolio
managers. In light of these objectives, the board of trustees considered
several alternative successor indexes and concluded that each proposed
Benchmark Index was best suited to achieve these goals. The board of
trustees believes that the modified performance adjustment will better
align the interests of each fund's shareholders and Pioneer. Specifically,
Pioneer recommended this change -- and the trustees determined to recommend
the change to shareholders -- based on the following:

Pioneer Mid Cap Growth Fund:

  * The fund is managed as a mid cap growth fund. The Russell Midcap Growth
    Index represents a portfolio with a similar focus, while the S&P 400 is a
    mid cap index comprised of stocks that are not chosen on the basis of a
    growth or value investment approach. Since the objective of a
    performance-based fee is to align the economic incentives of the
    management firm with the interests of shareholders, the trustees
    determined that basing the performance adjustment on the Russell Midcap
    Growth Index would better align Pioneer's economic incentives with the
    manner in which the fund is managed and consequently the economic interest
    of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of the fund in part upon the
    relative performance of the fund and the Russell Midcap Growth Index. This
    will similarly align the financial interests of the portfolio managers
    with those of the fund and Pioneer.

  * The board of trustees also considered alternative indexes, including peer
    group indexes, and concluded that the alternative indexes would not be as
    effective in achieving the goals of the performance fee. Peer group
    indexes were not considered desirable because the portfolio managers in
    managing the investments and risks of the fund need to know the
    composition of the portfolio against which they are being measured. Since
    the portfolio managers could not know the composition of the portfolios of
    the funds in the peer group, this inevitably would lead to using a peer
    group to measure performance but a securities index benchmark against
    which to manage the fund and measure risk. This would result in the
    portfolio managers having conflicting benchmarks against which their
    performance is measured for different purposes. While other securities
    indexes would be equally transparent to the portfolio managers, the
    trustees concluded that the Russell Midcap Growth Index is the securities
    index that most closely resembles the fund's investment style and risk
    characteristics.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the Russell Midcap Growth Index as the
    Benchmark Index since the adoption of a performance-based fee in 1996.
    While the results in individual years vary, overall the use of the Russell
    Midcap Growth Index would have resulted in a higher net management fee for
    Pioneer than the actual fee that Pioneer received. However, the board
    concluded that the benefits of the change in Benchmark Index outweighed
    this potential negative factor. The data provided to the trustees also
    demonstrated that the Russell Midcap Growth Index would result in a lower
    fee than a peer group index.

  * The trustees also considered the statistical correlation of the fund with
    the Russell Midcap Growth Index, the S&P 400 and other alternative indexes
    and found that the return of the Russell Midcap Growth Index is highly
    correlated with the return of the fund and that other indexes did not
    appear superior on this basis.

  * The Russell Midcap Growth Index is widely recognized and widely used by
    mutual funds and other institutional investment managers as a benchmark of
    U.S. equity performance. It is published daily in most newspapers that
    carry stock market information.

Pioneer Value Fund and Pioneer Mid Cap Value Fund:

  * The Lipper Growth and Income Index and the Lipper Growth Index are no
    longer widely available. The Russell indexes are widely recognized and
    widely used by mutual fund and other institutional investment managers as
    benchmarks of U.S. equity performance. They are published daily in most
    newspapers that carry stock market information.

  * Each fund is managed as a value fund, meaning that Pioneer seeks
    securities for the fund's portfolio that are reasonably priced or selling
    at substantial discounts to their underlying values. The Russell 1000
    Value Index and the Russell Midcap Value Index represent portfolios with
    similar focuses, i.e., portfolios of value-oriented stocks. Since the
    objective of a performance-based fee is to align the economic incentives
    of the management firm with the interests of shareholders, the trustees
    determined that basing the performance adjustments on the Russell 1000
    Value Index and the Russell Midcap Value Index would better align
    Pioneer's economic incentives with the manner in which the funds are
    managed and consequently the economic interest of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of these funds in part upon the
    relative performance of Pioneer Value Fund and the Russell 1000 Value
    Index and upon the relative performance of Pioneer Mid Cap Value Fund and
    the Russell Midcap Value Index. This will similarly align the financial
    interests of the portfolio managers with those of the fund and Pioneer.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Large Cap Value Index and the Lipper
    Mid-Cap Value Index, respectively, and concluded that the alternative
    indexes would not be as effective in achieving the goal of the performance
    fee. Peer group indexes were not considered desirable because the
    portfolio managers in managing the investments and risks of the fund need
    to know the composition of the portfolio against which they are being
    measured. Since the portfolio managers could not know the composition of
    the portfolios of the funds in the peer group, this inevitably would lead
    to using a peer group to measure performance but a securities index
    benchmark against which to manage the fund and measure risk. This would
    result in the portfolio managers having conflicting benchmarks against
    which their performance is measured for different purposes. While other
    securities indexes would be equally transparent to the portfolio managers,
    the trustees concluded that the Russell 1000 Value Index and Russell
    Midcap Value Index are the securities index that most closely resemble the
    respective fund's investment style and risk characteristics.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by each fund using the applicable Russell index as the Benchmark
    Index since the fund's adoption of a performance-based fee. While the
    results in individual years vary, overall the use of the Russell index
    would have resulted in a lower management fee for Pioneer from Pioneer
    Value Fund than the actual fee that Pioneer received or the fee that would
    have resulted using alternative peer group indexes. In the case of Pioneer
    Mid Cap Value Fund, the use of the Russell Midcap Value Index would have
    resulted in a higher management fee for Pioneer than either the actual fee
    Pioneer received or the fee that would have resulted using an alternative
    peer group index. However, the board of trustees concluded that the
    benefits of a change in the Benchmark Index outweighed this potentially
    negative factor. These historical comparisons are not necessarily
    indicative of the relative fees that would result from future performance.

  * The trustees also considered the statistical correlation of Pioneer Value
    Fund with the Russell 1000 Value Index, the Lipper index and other
    alternative indexes and the correlation of Pioneer Mid Cap Value Fund with
    the Russell Midcap Value Index, the Lipper index and other alternative
    indexes and found that the return of the Russell indexes are highly
    correlated with the return of the applicable fund and that other indexes
    did not appear superior on this basis.

Pioneer Fund:

  * The Lipper Growth and Income Index is no longer widely available. The S&P
    500 is widely recognized and widely used by mutual funds and other
    institutional investment managers as a benchmark of U.S. equity
    performance. It is published daily in most newspapers that carry stock
    market information. The trustees also considered Pioneer's belief that use
    of the S&P 500 as the Benchmark Index would help in imposing disciplines
    designed to ensure adherence to the fund's stated investment strategies
    and expected risk characteristics.

  * The fund is managed as a large cap/core fund, meaning that the fund
    primarily invests in large capitalization issuers with a balance between
    value and growth stocks. The S&P 500 represents a portfolio with a similar
    focus. The objective of a performance-based fee is to better align the
    economic incentives of the management firm with the interests of
    shareholders. Basing the performance adjustment on the S&P 500 would align
    Pioneer's economic incentives with the economic interest of shareholders.

  * Similarly, Pioneer intends to base the incentive compensation of its
    investment professionals in part upon the relative performance of the fund
    and the S&P 500. While Pioneer could use another index as the basis of its
    compensation, it believes that the use of a securities index offers the
    most objective means of measuring performance.

  * The board of trustees also considered alternative indexes, including
    other large cap indexes, such as the Russell 1000 and peer group index
    such as a Lipper index, and concluded that the alternative indexes would
    not be as effective in achieving the goal of the performance fee.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the S&P 500 as the Benchmark Index since the
    adoption of a performance based fee in 1996. While the results in
    individual years vary, overall the use of the S&P 500 would have resulted
    in a lower management fee for Pioneer than the actual fee that Pioneer
    received or the fee that would have resulted using alternative peer group
    indexes.

  * The trustees also considered the statistical correlation of the fund with
    the Lipper Growth and Income Index, the S&P 500 and other alternative
    indexes and found that the S&P 500 return is highly correlated with the
    return of the fund and that other indexes did not appear superior on this
    basis.

Pioneer Growth Shares:

  * The fund is managed as a large cap growth fund. The Russell 1000 Growth
    Index represents a portfolio with a similar focus, i.e., a portfolio of
    growth-oriented stocks, while the Russell 1000 is a large cap index
    comprised of stocks that are not chosen on the basis of a growth or value
    investment approach. Since the objective of a performance-based fee is to
    align the economic incentives of the management firm with the interests of
    shareholders, the trustees determined that basing the performance
    adjustment on the Russell 1000 Growth Index would better align Pioneer's
    economic incentives with the manner in which the fund is managed and
    consequently the economic interest of shareholders.

  * Pioneer intends to base the incentive compensation of its investment
    professionals engaged in the management of the fund in part upon the
    relative performance of the fund and the Russell 1000 Growth Index. Basing
    the performance adjustment on the Russell 1000 Growth Index would align
    Pioneer's economic incentives with the economic interest of shareholders.

  * The board of trustees also considered alternative indexes, including peer
    group indexes such as the Lipper Large-Cap Growth Index, and concluded
    that the alternative indexes would not be as effective in achieving the
    goals of the performance fee. Peer group indexes were not considered
    desirable because the portfolio managers in managing the investments and
    risks of the fund need to know the composition of the portfolio against
    which they are being measured. Since the portfolio managers could not know
    the composition of the portfolios of the funds in the peer group, this
    inevitably would lead to using a peer group to measure performance but a
    securities index benchmark against which to manage the fund and measure
    risk. This would result in the portfolio managers having conflicting
    benchmarks against which their performance is measured for different
    purposes. While other securities indexes would be equally transparent to
    the portfolio managers, the trustees concluded that the Russell 1000
    Growth Index is the securities index that most closely resembled the
    fund's investment style and risk characteristics.

  * The board of trustees reviewed data comparing the fee that would have
    been paid by the fund using the Russell 1000 Growth Index as the Benchmark
    Index since the adoption of a performance-based fee in 1999. While the
    results in individual years vary, overall the use of the Russell 1000
    Growth Index would have resulted in a higher net management fee for
    Pioneer than the actual fee that Pioneer received. However, the board of
    trustees concluded that the potential benefits of the proposed Benchmark
    Fee outweighed this potentially negative factor. This historical
    comparison is not necessarily indicative of the relative fees that would
    result from future performance.

  * The trustees also considered the statistical correlation of Pioneer
    Growth Shares with the Russell 1000 Growth Index, the Lipper Large-Cap
    Growth Index and other alternative indexes and found that the return of
    the Russell 1000 Growth Index is highly correlated with the return of the
    fund and that other indexes did not appear superior on this basis.

  * The Russell 1000 Growth Index is widely recognized and widely used by
    mutual fund and other institutional investment managers as a benchmark of
    U.S. equity performance. It is published daily in most newspapers that
    carry stock market information.

In approving the change regarding each fund's assumption of certain
categories of its operational expenses, the trustees considered the nature
of the expenses as appropriate fund expenses and the relevant practices of
other funds in the industry. The trustees also considered the intent of the
provision contained in the existing contract.

In evaluating each proposed contract, the Independent Trustees reviewed
materials furnished by Pioneer, including information regarding Pioneer,
UniCredito Italiano, their respective affiliates and their personnel,
operations and financial condition. The Independent Trustees discussed with
representatives of Pioneer the funds' operations and Pioneer's ability to
provide advisory and other services to the funds. The Independent Trustees
also reviewed, among other things:

  * the investment performance of each fund and other Pioneer Funds with
    similar investment strategies for the one-, three- and five-year periods
    ended December 31, 2002, and the return of the Benchmark Index for the
    same period;

  * the fee charged by Pioneer for investment advisory and administrative
    services, as well as other compensation received by PFD and PIMSS;

  * each fund's projected total operating expenses;

  * the investment performance, fees and total expenses of investment
    companies with similar objectives and strategies managed by other
    investment advisers;

  * the experience of the investment advisory and other personnel providing
    services to the funds and the historical quality of the services provided
    by Pioneer; and

  * the profitability to Pioneer of managing the funds.

The Independent Trustees considered the following as relevant to their
recommendations that the shareholders approve the proposed contracts: (i)
the favorable history, reputation, qualification and background of Pioneer
and UniCredito Italiano, as well as the qualifications of their personnel
and their respective financial conditions; (ii) that the fee and expense
ratio of each fund are reasonable given the quality of services expected to
be provided and are comparable to the fees and expense ratios of similar
investment companies; and (iii) the relative performance of each fund since
commencement of operations to comparable investment companies and unmanaged
indexes; and (iv) other factors that the Independent Trustees deemed
relevant. The Independent Trustees deemed each of these factors to be
relevant to their consideration of the proposed contracts.

Based upon all of the above considerations, the trustees determined that
both the modification of the performance adjustment and the assumption of
certain fund expenses would be equitable and fair to the shareholders of
each fund and that their adoption will make it more likely that the
objectives of continued levels of good service and investment performance
currently and in the future will be achieved.

Trustees' recommendation

Based on their evaluation of the materials presented and assisted by the
advice of independent counsel, the trustees who were present at the meeting
on December 3, 2002, including all of the trustees who are not "interested
persons" of the funds or Pioneer, unanimously concluded that each proposed
contract was fair and reasonable and in the best interests of the fund's
shareholders and by a vote cast at the meeting, approved and voted to
recommend to the shareholders of the fund that they approve the proposal to
terminate the existing contract and to adopt the proposed contract.

Required vote

Adoption of Proposal 2 requires the approval of a majority of the
outstanding voting securities of the fund, which under the 1940 Act, means
the affirmative vote of the lesser of (i) 67% or more of the shares of the
fund represented at the meeting, if at least 50% of all outstanding shares
of the fund are represented at the meeting, or (ii) 50% or more of the
outstanding shares of the fund entitled to vote at the meeting (a "1940 Act
Majority Vote").

If Proposal 2 is not approved by shareholders, the existing contract will
continue in effect.

Recommendation

For the reasons set forth above, the trustees of your fund unanimously
recommend that shareholders vote in favor of the proposed contract.

PROPOSAL 3

APPROVAL OF A POLICY ALLOWING PIONEER AND THE BOARD OF TRUSTEES TO APPOINT
OR TERMINATE SUBADVISERS AND TO APPROVE AMENDMENTS TO SUBADVISORY
AGREEMENTS WITHOUT SHAREHOLDER APPROVAL

Summary

At the board of trustees' meeting held February 6, 2001, the trustees,
including the Independent Trustees, approved, and recommended that
shareholders of the fund approve, a policy to permit Pioneer to appoint
subadvisers, to enter into subadvisory agreements and to amend or terminate
existing subadvisory agreements without further shareholder approval (the
"subadviser approval policy"). Any such appointment or termination would be
subject to prior approval of the board of trustees, including a majority of
the Independent Trustees. Pioneer currently does not intend to appoint a
subadviser with respect to any of the funds.

The Section 15 exemptive order

On May 6, 2002, the funds, the other funds in the Pioneer Family of Funds
and Pioneer obtained an exemptive order from the SEC (the "exemptive
order") relieving them from certain provisions of Section 15(a) of the 1940
Act and Rule 18f-2 thereunder in connection with the subadviser approval
policy. The exemptive order applies to Pioneer Funds that meet the
conditions of the order. The provisions of the 1940 Act require that
shareholders of a mutual fund approve a subadvisory agreement with the
subadviser and material amendments to an existing subadvisory agreement. If
shareholders approve this proposal, Pioneer will be authorized, subject to
approval by the board of trustees, to evaluate, select and retain one or
more subadvisers for each fund, terminate or replace any subadviser so
approved or modify any subadvisory agreement with respect to any fund
without obtaining further approval of the fund's shareholders. The trustees
and Pioneer would be authorized to take such actions whenever they
determine that such actions will benefit a fund and its shareholders.

Shareholder approval policy

Pioneer has served as the investment adviser to each fund since its
inception, except for Pioneer Growth Shares for which Pioneer has served as
investment adviser since 1993. Pioneer represents that it has the
experience and expertise to evaluate, select and supervise subadvisers who
can add value to shareholders' investments in the funds.

Proposed subadviser approval policy. Approval of the subadviser approval
policy will not affect any of the requirements under the federal securities
laws that govern any of the funds, Pioneer, any proposed subadviser, or any
proposed subadvisory agreement, other than the requirement to have a
subadvisory agreement approved at a meeting of the fund's shareholders. The
board of trustees of each fund, including the Independent Trustees, will
continue to evaluate and approve all new subadvisory agreements between
Pioneer and any subadviser as well as all changes to any subadvisory
agreements. In addition, the fund and Pioneer will be subject to several
conditions imposed by the SEC to ensure that the interests of the fund's
shareholders are adequately protected whenever Pioneer acts under the
subadviser approval policy. Furthermore, within 90 days of the adoption of
or a change to the fund's subadvisory arrangements, the fund will provide
you with an information statement that contains substantially the same
relevant information about the subadviser, the subadvisory agreement and
the subadvisory fee that the fund would be required to send to you in a
proxy statement. This information statement will permit the fund's
shareholders to determine if they are satisfied with the subadvisory
arrangement. If not satisfied, the shareholders would be able to exchange
their shares for another fund or redeem their shares. Exchanges and
redemptions may be subject to transaction or distribution fees and
generally are taxable transactions.

Shareholder approval of this proposal will not result in an increase or
decrease in the total amount of investment advisory fees paid by the fund
to Pioneer. If the fund implements this policy, Pioneer, pursuant to its
management contract with the fund, will continue, directly or through
subadvisers, to provide the same level of management and administrative
services to the fund as it has always provided. The funds will not be
responsible for the payment of any subadvisory fees.

The exemptive relief applies to at least the following situations: (1)
Pioneer determines to retain a subadviser for all or a portion of any
fund's assets; (2) a subadviser is removed for substandard performance; (3)
an individual acting as a fund's portfolio manager moves from employment
with one subadviser to another firm, which Pioneer then appoints as a
subadviser; (4) there is a change of control of a subadviser; (5) Pioneer
decides to diversify a fund's management by adding a or additional
subadvisers; (6) there is a change in investment style of a fund; and (7)
Pioneer negotiates a reduction (or the subadviser negotiates an increase)
in the subadvisory fee that Pioneer pays to a subadviser. If Pioneer
negotiates a decrease in the compensation that it pays any subadviser and
effectively retains more of the advisory fee for itself, no shareholder
action would be required. The subadviser approval policy will not be used
to approve any subadviser that is affiliated with Pioneer as that term is
used in the 1940 Act or to materially amend any subadvisory agreement with
an affiliated subadviser. Instead, a special shareholder meeting would be
called to permit shareholders to approve any subadvisory arrangement with
an affiliated subadviser.

Reasons for requesting Section 15 exemptive relief

The trustees believe that it is in the best interest of each fund and its
shareholders to allow Pioneer the flexibility to provide its investment
advisory services to the fund through one or more subadvisers which have
particular expertise in the type of investments on which the fund focuses.
In addition, the trustees believe that providing Pioneer with maximum
flexibility to select, supervise and evaluate subadvisers -- without
incurring the necessary delay or expense of obtaining further shareholder
approval -- is in the best interest of each fund's shareholders because it
will allow the fund to operate more efficiently. Currently, in order for
Pioneer to appoint a subadviser or materially modify a subadvisory
agreement, the fund must call and hold a shareholder meeting of the fund,
create and distribute proxy materials, and solicit votes from the fund's
shareholders. This process is time-intensive, costly and slow. Without the
delay inherent in holding shareholder meetings, Pioneer would be able to
act more quickly to appoint a subadviser when the trustees and Pioneer feel
that the appointment would benefit the fund.

Also, the trustees believe that it is appropriate to vest the selection,
supervision and evaluation of the subadvisers in Pioneer (subject to review
by the board of trustees) in light of Pioneer's expertise in investment
management and its ability to select the most appropriate subadviser(s).
The trustees believe that many investors choose to invest in the funds
because of Pioneer's investment management experience and expertise.
Pioneer believes that, if it becomes appropriate to appoint a subadviser to
a fund, it can use this experience and expertise in evaluating and choosing
subadvisers who can add the most value to your investment in that fund.
Pioneer also has experience in retaining and supervising subadvisers, with
Pioneer Real Estate Shares, Pioneer Real Estate Shares VCT Portfolio,
Pioneer Balanced Fund, Pioneer Balanced VCT Portfolio, Pioneer Europe Fund
and Pioneer Indo-Asia Fund (which has been combined with Pioneer Emerging
Markets Fund) having subadvisers at one time, although Pioneer does not
currently employ a subadviser with respect to any Pioneer fund.

Finally, the trustees will provide sufficient oversight of the subadviser
approval policy to ensure that shareholders' interests are protected
whenever Pioneer selects a subadviser or modifies a subadvisory agreement.
The board, including a majority of the Independent Trustees, will continue
to evaluate and approve all new subadvisory agreements as well as any
modification to existing subadvisory agreements. In their review, the
trustees will analyze all factors that they consider to be relevant to the
determination, including the nature, quality and scope of services provided
by the subadvisers. The trustees will compare the investment performance of
the assets managed by the subadviser with other accounts with similar
investment objectives managed by other advisers and will review the
subadviser's compliance with federal securities laws and regulations. Each
subadvisory agreement will be subject to all provisions of the 1940 Act,
except for the specific provisions of the 1940 Act from which the exemptive
order provides relief.

Required vote

Approval of this proposal requires the affirmative 1940 Act Majority Vote
(as defined in Proposal 2 above) of the fund's outstanding shares. If the
fund does not approve this proposal, the subadviser approval policy will
not be adopted and decisions regarding a proposed subadviser or a material
change to a subadvisory agreement will continue to require shareholder
approval.

Recommendation

For the reasons set forth above, the trustees of your fund unanimously
recommend that shareholders vote in favor of the proposed policy allowing
Pioneer and the board of trustees to appoint or terminate subadvisers and
to approve amendments to subadvisory agreements without shareholder
approval.

PROPOSALS 4(a) THROUGH 4(p)
ELIMINATION OR AMENDMENT OF VARIOUS INVESTMENT RESTRICTIONS/POLICIES

General

Pioneer and your board of trustees recommend that the changes discussed
below be made to simplify and modernize your fund's fundamental investment
restrictions and conform them to the restrictions adopted by other Pioneer
Funds. We are asking you to vote on these changes because the restrictions
described below are fundamental and may be changed only with shareholder
approval. For Pioneer Value Fund you are also being asked to convert some
fundamental investment policies into non-fundamental polices, permitting
the board of trustees to amend them in the future without shareholder
action.

The 1940 Act requires mutual funds to adopt fundamental investment
restrictions covering certain types of investment practices. The funds,
however, are also subject to a number of other fundamental restrictions
that are not required by the 1940 Act or any other current laws or are more
restrictive than required by such laws. Each current investment restriction
or policy, the corresponding proposed restriction or policy and the funds'
rationale for the change are set forth below.

Pioneer expects that you will benefit from these proposed changes to the
funds' investment restrictions in several ways. The funds would have
increased flexibility to respond to new developments and changing trends in
the marketplace, making the funds' powers comparable to most other recently
organized mutual funds. Pioneer believes that this added flexibility will
make each fund more competitive among its peer group of funds. The proposed
changes to the funds' investment restrictions are also designed to produce
a clearer and more concise set of restrictions. These revised restrictions
parallel the investment restrictions of other funds managed by Pioneer,
which will facilitate Pioneer's compliance efforts.

Proposed amendment to investment restrictions

The table below sets forth each fund's current fundamental restrictions in
the left-hand column and the proposed amended restrictions in the
right-hand column. The amended restrictions, if approved, will be revised
in the fund's amended statement of additional information. Pioneer does not
anticipate that the approval of these changes will result in any material
modification of the funds' operations at the present time. Statements in
italics are not part of the proposed investment restriction.

                                                below are not deemed to be
                                                senior securities.


The 1940 Act generally prohibits a mutual fund from issuing senior
securities except in connection with borrowing permitted under the 1940
Act. The SEC's staff has taken the position that certain types of
investment techniques fall within the 1940 Act's definition of senior
security but are not prohibited if the fund takes certain measures to
prevent the technique or investment from having a leveraging effect on the
fund. For example, a fund may write a call option on a security only if the
option is covered, that is the fund owns or has the right to acquire the
security underlying the option. The proposed revisions to each fund's
investment restriction on senior securities are intended to provide broad
authority to the board of trustees to permit the fund to issue instruments
or engage in investment techniques that may be deemed to be senior
securities and to clarify that the fund may issue senior securities to the
extent permitted by the 1940 Act and the rules and interpretive positions
of the SEC. The current formulation, that uses an enumeration of permitted
activities, entails the risk that future investment products or techniques
may fall within the 1940 Act's definition of a senior security but would be
exempt from treatment as senior securities pursuant to interpretive
positions of the SEC. Under the current restriction, each fund may not be
permitted to engage in any investment technique or product that may be
deemed in the future to involve the issuance of a senior security without
shareholder approval, while competitive funds may be able to engage in such
activities without the delay and cost of shareholder action. In addition,
the revised restriction is drafted in a clearer, more readily
understandable manner. The adoption of the amended restrictions is not
anticipated to have any immediate effect on the funds' investment policies
or the instruments in which they invest.

This amendment would promote uniformity in the fundamental policy on
borrowing among Pioneer funds. These changes afford each fund the maximum
flexibility to borrow money permitted under the 1940 Act if the board and
Pioneer determine that such borrowing is in the best interests of the fund
and is consistent with both the fund's investment objective and with the
requirements of the 1940 Act. The proposal does not reflect a change in any
fund's anticipated borrowing activity. Currently, none of the funds borrow
money except in connection with the settlement of securities transactions
and each fund has access to a line of credit in the event of unusual
redemption activity (which none of the funds has drawn upon in the last
twelve months). For certain funds, the percentage limitation on borrowing
effectively would be revised upward from 10% to 33 1/3% of the fund's total
assets. This change significantly increases the total amount the funds are
permitted to borrow. An additional 5% authority for temporary purposes is
proposed to be added to conform to the percentage limitation included in
the 1940 Act. The authority to obtain short-term credits would help to
facilitate the clearance of portfolio transactions and, to the extent
determined advisable for portfolio management reasons, reduce the cash
position the fund needs to maintain. Margin purchases would also be
permitted to the extent allowed by law. The 1940 Act allows the SEC the
authority to adopt regulations restricting the use of margin by investment
companies. While no such regulations have been adopted, the SEC has
indicated that it considers margin transactions to involve the issuance of
senior securities, which is restricted under the 1940 Act. To the extent
that a fund borrows to purchase securities or purchases securities on
margin, the fund may incur risks associated with leverage. The use of
leverage may cause the fund's net asset value to be more volatile and
increase the risk of loss.

                        Pioneer Mid Cap         The fund may not invest in
                        Value Fund              real estate or interests therein,
                                                excluding readily marketable
                                                securities of companies that
                                                invest in real estate or real
                                                estate investment trusts.


The 1940 Act requires that each fund adopt a fundamental policy regarding
whether the fund may invest in real estate. The purpose of this requirement
is to allow investors in the fund to clearly understand the permitted scope
of the fund's investments since an investment in real estate involves
significantly different investment experience and risks than an investment
in securities. However, an investment in real estate related securities
primarily requires portfolio management expertise rather than a specific
expertise in real estate management. Pioneer employs portfolio managers and
analysts who specialize in such real estate related securities. The purpose
of the amendment is to more clearly express the intention that each fund
will not directly invest in real estate but may invest in issuers in real
estate related businesses, such as real estate investment trusts (REITs),
or in fixed income securities secured by real estate. The proposed
amendment will, therefore, clarify that the fund's investments may include
real estate related opportunities that are within the scope of its
investment objective and policies. The revision would also clarify that a
fund could exercise its rights under a permitted instrument, such as
foreclosure under a bond secured by real estate, even if the exercise of
those rights results in the fund obtaining a direct interest in real
estate.

The 1940 Act requires that each fund adopt a fundamental policy with
respect to making loans. This amendment would promote uniformity among
Pioneer funds and clarify that the funds can engage in such forms of
investment in fixed income securities as purchasing participation interest
in commercial loans. These changes afford each fund the maximum flexibility
to make loans to the extent permitted under the 1940 Act. The proposal does
not reflect a change in the funds' activities. The change also would allow
each fund to take part in an inter-fund lending program, if such a program
were approved by the board. While the funds have no current plans to make
loans between funds, the funds have obtained an exemptive order that would
permit a fund to lend any excess cash held by such fund to any other
Pioneer fund. The intention of such an inter-fund lending arrangement would
be to provide greater liquidity to the borrowing fund and a higher rate of
return to the lending fund than might be available from other cash
management investments. Such an arrangement entails a risk of loss if the
borrowing fund were to default on its obligation to the lending fund.

The 1940 Act requires that each fund adopt a fundamental policy with
respect to commodities. The original purpose of the restriction was to
clarify that a fund would not be investing in traditional commodity
contracts, particularly agricultural commodities such as wheat futures.
This amendment would conform the investment restriction on commodities with
the restriction used by other Pioneer Funds and would avoid including a
list of specifically exempted financial instruments, which list could
quickly become outdated. These changes afford each fund the maximum
flexibility to invest in commodities to the extent permitted under the 1940
Act, allowing the funds to take advantage of new investment products that
may technically be commodities. By stating the exception to the general
prohibition on commodities as being applicable to financial instruments
rather than a specific list of financial instruments, the goal is to
prevent technical concerns from limiting the fund's investment
opportunities.

maximum flexibility to comply with the requirements of the 1940 Act and
interpretations thereof as they may change from time to time.

This policy was originally required by blue sky regulations, but it is not
required under the 1940 Act. It is not intended that the elimination of
this restriction will result in any fund guaranteeing the obligations of
any third party or the pledging of fund assets.

                        Fund


A fund is not required to have a fundamental restriction on its ability to
engage in margin transactions. Under the funds' proposed fundamental
policies on borrowing and senior securities, margin purchases would be
permitted to the extent allowed by law. This includes a fund's ability to
use "short-term credits" for clearing transactions and margin deposits in
connection with options, futures and forwards. The 1940 Act grants the SEC
the authority to adopt regulations restricting the use of margin by
investment companies. While no such regulations have been adopted, the SEC
has indicated that it considers margin transactions to involve the issuance
of senior securities, which is restricted under the 1940 Act.

                                                                                        short sales, except short sales

The 1940 Act does not require that an investment company's policy with
respect to short sales be fundamental. Each fund would adopt a
non-fundamental restriction (that could be amended or eliminated in the
future without shareholder approval) to limit short sales to short sales
"against-the-box". In a short sale against-the-box, the fund owns or has
the right to acquire the security sold short.

The SEC requires disclosure of a fund's policy if it "intends to invest in
companies for the purpose of exercising control," but there is no
requirement that a fund specify that it will not invest in companies for
the purpose of exercising control. Since the funds do not invest for the
purpose of exercising control over portfolio companies, the proposal would,
therefore, eliminate a policy that is not required. The funds, however,
have no current intention of investing in any portfolio company for the
purpose of taking control of the management of that company.

                                                the fund from investing in the
                                                securities issued by a real estate
                                                investment trust, provided that
                                                such trust shall not be permitted
                                                to invest in real estate or interests
                                                in real estate other than mortgages
                                                or other security interests.


The board proposes eliminating the current fundamental restriction because
it is not required by the 1940 Act and potentially limits the flexibility
of the funds to make desirable investments. The funds' ability to invest in
other investment companies, including other investment companies managed by
Pioneer, would continue to be restricted (but not prohibited) by the 1940
Act.

                                                securities except that the
                                                delivery requirements are
                                                different. The fund may sell a
                                                securities index option it has
                                                purchased or write a similar
                                                option prior to the expiration
                                                of the purchased option in
                                                order to close out its position
                                                in a securities index option
                                                which it has purchased.
                                                The fund may also allow
                                                options to expire unexercised,
                                                which would result in the loss
                                                of the premium paid. The
                                                fund will not invest more than
                                                20% of its net assets in
                                                premiums on index put and
                                                call options.

                                                The fund may also invest a
                                                portion of its portfolio in
                                                temporary cash investments
                                                including finance company

                                                quality as determined
                                                by Pioneer.


While all of the Pioneer funds treat their investment objectives as
fundamental, only Pioneer Value Fund has investment policies that are
designated as fundamental. The fund's board would designate these policies
non-fundamental policies and would be able to revise them without
shareholder approval. Although there is currently no intention to change
the manner in which the fund is managed, there is less flexibility for the
board and Pioneer to adapt this fund to future changes in the market. With
respect to dividends, Pioneer believes that the current policy
unnecessarily highlights one aspect of the fund's investment approach.

Each fund has agreed to certain investment restrictions as a condition of
registration in the Federal Republic of Germany, Austria and Switzerland.
Currently, the board of trustees may not modify these restrictions to take
advantage of changing regulatory policies in foreign jurisdictions without
incurring the expense and delay associated with obtaining shareholder
approval. Proposal 4(o), if approved, would allow each fund the flexibility
to amend the above investment restrictions to take advantage of changes in
regulatory policies in these jurisdictions without the need to seek
shareholder approval. The investment restrictions could then be changed
with the approval of the trustees provided the trustees consider such
changes to be in the best interests of the fund. Pioneer Mid Cap Growth
Fund and Pioneer Growth Shares are not subject to any of these
international investment restrictions. The shareholders of Pioneer Mid Cap
Value Fund approved a similar policy change in April 1998. No change would
be effected until the funds' prospectuses and statements of additional
information had been amended or supplemented as necessary to reflect the
change.

On July 3, 2002, the funds, Pioneer, PFD and other funds in the Pioneer
Family of Funds were granted an SEC exemptive order that would permit the
funds to invest uninvested cash and cash collateral in Pioneer Cash
Reserves Fund, an affiliated investment company. Without the exemptive
relief, the funds are prohibited by the 1940 Act from engaging in joint
transactions with an affiliated fund. The current restriction was initially
adopted to qualify the funds for registration in Germany, Switzerland and
Austria. The amended restriction would afford each fund the flexibility to
invest cash balances and collateral held in connection with the funds'
securities lending program in Pioneer Cash Reserves Fund and maintain its
qualification for registration in Germany, Switzerland and Austria. No
change would be effected until the funds' prospectuses and statements of
additional information had been amended or supplemented as necessary to
reflect the new restriction.

Trustees' recommendation

The trustees believe that the proposed amendments to each fund's
fundamental restrictions will more clearly reflect current regulatory
practice and will expand the investment opportunities available to the
fund. Accordingly, the trustees recommend that you approve the proposed
changes as described above.

Required vote

Approval of each of Proposals 4(a) through 4(p) requires the affirmative
1940 Act Majority Vote (as defined in Proposal 2 above) of the fund's
outstanding shares. If the required approval to change any restriction is
not obtained, the current investment restriction will continue in effect.

Recommendation

For the reasons set forth above, trustees of your fund unanimously
recommend that shareholders vote for each proposal to amend the fund's
investment restrictions.

INFORMATION CONCERNING THE MEETING

Outstanding shares and quorum

See Exhibit C to this proxy statement for the number of shares of
beneficial interest of each fund that were outstanding as of the record

beneficially in the aggregate less than 1% of the outstanding shares of
that fund. Each person that, to the knowledge of the funds, owned of record

Shareholder proposals

The funds are not required to hold annual meetings of shareholders and do
not currently intend to hold meetings of shareholders in 2003. Shareholder
proposals intended to be presented at the next meeting of shareholders of a
fund, whenever held, must be received at the funds' offices, 60 State
Street, Boston, Massachusetts 02109, at a reasonable time prior to the
trustees' solicitation of proxies for the meeting. The submission by a
shareholder of a proposal for inclusion in a proxy statement does not
guarantee that it will be included. Shareholder proposals are subject to
certain regulations under the federal securities laws.

Shares held in retirement plans

The trustee or custodian of certain retirement plans is required to vote
any unvoted fund shares held in such plans in proportion to the percentages
voted by shareholders in person or by proxy.

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 funds. In addition, although mere attendance at the shareholder
meeting will not revoke a proxy, a shareholder present at the shareholder
meeting may withdraw his or her proxy and vote in person. All properly
executed and unrevoked proxies received in time for the shareholder 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 proposals described above and
will use their best judgment in connection with the transaction of such
other business as may properly come before the shareholder meeting or any
adjournment thereof.

On each proposal, all classes of shares of a fund vote as a single class.
One-third of the outstanding shares of a fund that are entitled to vote,
present in person or represented by proxy, constitutes a quorum for the
transaction of business with respect to any proposal for that fund;
however, since each proposal, other than the election of trustees, must be
approved by a 1940 Act Majority Vote, at least 50% of the outstanding
shares must be present in person or by proxy at the meeting to approve any
of the proposals. In the event that at the time any session of the
shareholder meeting is called to order, a quorum is not present in person
or by proxy, the persons named as proxies may vote those proxies which 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 any of the
proposals 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 shareholder
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 each fund represented in person or by proxy, including shares
which abstain or do not vote with respect to a proposal, will be counted
for purposes of determining whether there is a quorum at the shareholder
meeting. Accordingly, an abstention from voting has the same effect as a
vote against a proposal, except for the proposal to elect trustees.
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 be considered present and entitled to vote on that
proposal. Thus, a "broker non-vote" has no effect on the voting to elect
trustees but has the same effect as a vote against the other proposals.

Other business

While the shareholder 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 special meeting
of shareholders. However, if any additional matters properly come before
the shareholder meeting, and on all matters incidental to the conduct of
the meeting, the persons named in the enclosed proxy intend 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, the
attached notice of special meeting of shareholders and the accompanying
proxy card(s) will be borne by Pioneer. In addition to soliciting proxies
by mail, Pioneer may, at its expense, have one or more of the funds'
officers, representatives or compensated third-party agents, including
Pioneer, PIMSS and PFD or Alamo Direct, professional proxy solicitors, who
will be paid fees and expenses of approximately $25,000 for their
soliciting services, 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.

The funds 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. The funds are unaware of any such challenge at
this time. In the case of telephone voting, shareholders would be called at
the phone number PIMSS 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 identifying information and will 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.

EXHIBIT A
AUDIT COMMITTEE CHARTER
PIONEER FUNDS

Function. Oversight is the primary function of the Audit Committee,
comprised exclusively of independent Trustees of the Pioneer Funds (the
"Funds"). The management company is responsible for maintaining appropriate
systems for accounting and internal controls and the independent auditor is
responsible for planning and carrying out proper audits.

Purposes. The purposes of the Audit Committee are to:

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

2.  discuss with the Funds' independent auditors their judgments about the
    quality of the Fund's accounting principles and underlying estimates as
    applied in the Funds' financial reporting;

3.  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;

4.  review and assess from time to time, as it deems necessary and
    appropriate:

    (a) brokerage and soft dollar arrangements of the Funds,

    (b) the utilization of the Funds' line of credit, and

    (c) "as of" gain/loss activity of the funds;

5.  review and approve insurance coverage and allocations of premiums
    between the management and the Funds and among the Funds;

6.  review and approve expenses under the Administration Agreements between
    the management company and the Funds and allocations of such expenses
    among the Funds; and

7.  ensure that the independent auditors submit on a periodic basis to the
    audit committee a formal written statement delineating all relationships
    between the auditors and the company; to actively 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.

Activities. To carry out its function and its purposes, the Committee
shall, as appropriate and necessary:

    (a) recommend the selection, retention or termination of auditors;
        and, in connection therewith, to evaluate the independence of
        the auditors, including whether the auditors provide any
        consulting services to the manager or to vendors to the Funds,
        whose systems are material to the Funds' operations, regarding
        their systems and controls; and to receive the auditors' specific
        representations as to their independence;

    (b) meet with the Funds' independent auditors, including private
        meetings, as necessary to (i) review the arrangements for
        and scope of the annual audit and any special audits; (ii) to
        discuss any matters of concern relating to the Funds' financial
        statements, including any adjustments to such statements
        recommended by the auditors, or any other results of the audits;
        (iii) consider the auditors' comments with respect to the Funds'
        financial policies, procedures and internal accounting controls
        and management's responses thereto; and (iv) review the form of
        opinion the auditors propose to render to the Board and shareholders;

     (c) consider the effect upon the Funds of any changes in accounting
         principles or practices proposed by management or the auditors;

     (d) review the fees charged by the auditors for audit and non-audit
         services;

     (e) investigate improprieties or suspected improprieties in fund
         operations; and

     (f) report its activities to the full Board on a regular basis and
         to make such recommendations with respect to the above and other
         matters as the Committee may deem necessary or appropriate.

Governance and Compensation. The Committee shall be comprised of three
independent Trustees of the Funds who shall be nominated and elected
annually by the Board of Trustees of the Funds. Members of the Committee
shall elect from among them a Chairperson, who shall preside over meetings
of the Committee. Replacements for vacancies, occurring from time to time,
shall be nominated and elected by the remaining Trustees of the Funds.

The Committee shall meet on a regular basis and is empowered to hold
special meetings, as circumstances require. The Committee shall meet
regularly with the Treasurer of the Funds. The Committee shall have the
resources and authority appropriate to discharge its responsibilities,
including the authority to retain special counsel and other experts or
consultants at the expense of the appropriate Funds.

Compensation for the members of the Committee shall be determined by the
Board of Trustees. It is expected that the Chairperson will receive
additional compensation for her/his services as Chair.

Initial Approval and Annual Review of Charter. This Charter is subject to
approval of the Board of Trustees of the Funds. The Committee shall review
this Charter at least annually and recommend any changes to the Board for
its consideration.

EXHIBIT B
FORM OF PROPOSED MANAGEMENT CONTRACT


THIS AGREEMENT dated as of this 1st day of May, 2003 between [name of
fund], a Delaware business trust (the "Trust"), and Pioneer Investment
Management, Inc., a Delaware corporation (the "Manager").

W I T N E S S E T H

WHEREAS, the Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940
Act"), and has filed with the Securities and Exchange Commission (the
"Commission") a registration statement for the purpose of registering its
shares for public offering under the Securities Act of 1933, as amended
(the "1933 Act").

WHEREAS, the parties hereto deem it mutually advantageous that the Manager
should be engaged, subject to the supervision of the Trust's Board of
Trustees and officers, to manage the Trust.

NOW, THEREFORE, in consideration of the mutual covenants and benefits set
forth herein, the Trust and the Manager do hereby agree as follows:

1.  The Manager will regularly provide the Trust with investment research,
    advice and supervision and will furnish continuously an investment program
    for the Trust, consistent with the investment objective and policies of
    the Trust. The Manager will determine from time to time what securities
    shall be purchased for the Trust, what securities shall be held or sold by
    the Trust and what portion of the Trust's assets shall be held uninvested
    as cash, subject always to the provisions of the Trust's Certificate of
    Trust, Agreement and Declaration of Trust, By-Laws and its registration
    statements under the 1940 Act and under the 1933 Act covering the Trust's
    shares, as filed with the Commission, and to the investment objective,
    policies and restrictions of the Trust, as each of the same shall be from
    time to time in effect, and subject, further, to such policies and
    instructions as the Board of Trustees of the Trust may from time to time
    establish. To carry out such determinations, the Manager will exercise
    full discretion and act for the Trust in the same manner and with the same
    force and effect as the Trust itself might or could do with respect to
    purchases, sales or other transactions, as well as with respect to all
    other things necessary or incidental to the furtherance or conduct of such
    purchases, sales or other transactions.

2.  The Manager will, to the extent reasonably required in the conduct of
    the business of the Trust and upon the Trust's request, furnish to the
    Trust research, statistical and advisory reports upon the industries,
    businesses, corporations or securities as to which such requests shall be
    made, whether or not the Trust shall at the time have any investment in
    such industries, businesses, corporations or securities. The Manager will
    use its best efforts in the preparation of such reports and will endeavor
    to consult the persons and sources believed by it to have information
    available with respect to such industries, businesses, corporations or
    securities.

3.  The Manager will maintain all books and records with respect to the
    Trust's securities transactions required by subparagraphs (b)(5), (6), (9)
    and (10) and paragraph (f) of Rule 31a-1 under the 1940 Act (other than
    those records being maintained by the custodian or transfer agent
    appointed by the Trust) and preserve such records for the periods
    prescribed therefor by Rule 31a-2 under the 1940 Act. The Manager will
    also provide to the Board of Trustees such periodic and special reports as
    the Board may reasonably request.

4.  Except as otherwise provided herein, the Manager, at its own expense,
    shall furnish to the Trust office space in the offices of the Manager, or
    in such other place as may be agreed upon from time to time, and all
    necessary office facilities, equipment and personnel for managing the
    Trust's affairs and investments, and shall arrange, if desired by the
    Trust, for members of the Manager's organization to serve as officers or
    agents of the Trust.

5.  The Manager shall pay directly or reimburse the Trust for: (i) the
    compensation (if any) of the Trustees who are "affiliated persons" (as
    defined in the 1940 Act) of the Manager and all officers of the Trust as
    such; and (ii) all expenses not hereinafter specifically assumed by the
    Trust where such expenses are incurred by the Manager or by the Trust in
    connection with the management of the affairs of, and the investment and
    reinvestment of the assets of, the Trust.

6.  The Trust shall assume and shall pay: (i) charges and expenses for fund
    accounting, pricing and appraisal services and related overhead,
    including, to the extent such services are performed by personnel of the
    Manager or its affiliates, office space and facilities, and personnel
    compensation, training and benefits; (ii) the charges and expenses of
    auditors; (iii) the charges and expenses of any custodian, transfer agent,
    plan agent, dividend disbursing agent, registrar or any other agent
    appointed by the Trust; (iv) issue and transfer taxes chargeable to the
    Trust in connection with securities transactions to which the Trust is a
    party; (v) insurance premiums, interest charges, dues and fees for
    membership in trade associations and all taxes and corporate fees payable
    by the Trust to federal, state or other governmental agencies; (vi) fees
    and expenses involved in registering and maintaining registrations of the
    Trust and/or its shares with federal regulatory agencies, state or blue
    sky securities agencies and foreign jurisdictions, including the
    preparation of prospectuses and statements of additional information for
    filing with such regulatory authorities; (vii) all expenses of
    shareholders' and Trustees' meetings and of preparing, printing and
    distributing prospectuses, notices, proxy statements and all reports to
    shareholders and to governmental agencies; (viii) charges and expenses of
    legal counsel to the Trust and the Trustees; (ix) any fees paid by the
    Trust in accordance with Rule 12b-1 promulgated by the Commission pursuant
    to the 1940 Act; (x) compensation of those Trustees of the Trust who are
    not affiliated with, or "interested persons" of, the Manager, the Trust
    (other than as Trustees), Pioneer Investment Management USA, Inc. or
    Pioneer Funds Distributor, Inc.; (xi) the cost of preparing and printing
    share certificates; (xii) interest on borrowed money, if any; and (xiii)
    any other expense that the Trust, the Manager or any other agent of the
    Trust may incur (A) as a result of a change in the law or regulations, (B)
    as a result of a mandate from the Board of Trustees with associated costs
    of a character generally assumed by similarly structured investment
    companies or (C) that is similar to the expenses listed above, and that
    is approved by the Board of Trustees (including a majority of the
    Independent Trustees) as being an appropriate expense of the Trust.

7.  In addition to the expenses described in Section 6 above, the Trust
    shall pay all brokers' and underwriting commissions chargeable to the
    Trust in connection with securities transactions to which the Trust is a
    party.

8.  The Trust shall pay to the Manager, as compensation for the Manager's
    services and expenses assumed hereunder, a fee as set forth below.
    Management fees payable hereunder shall be computed daily and paid monthly
    in arrears.

A)  The fee payable hereunder shall be composed of the Basic Fee (defined
    below) and a Performance Adjustment (defined below) to the Basic Fee based
    upon the investment performance of the Trust in relation to the investment
    record of a securities index determined by the Trustees of the Trust to be
    appropriate over the same period. The Trustees have designated the [name
    of new Benchmark Index] (the "Index") for this purpose; provided, however,
    that for all periods prior to May 1, 2003, the securities index shall be
    the [name of current Benchmark Index].

B)  From time to time, the Trustees may by a vote of the Trustees of the
    Trust voting in person, including a majority of its Trustees who are not
    parties to this Agreement or "interested persons" (as defined in the 1940
    Act) of any such parties, determine 1) that another securities index is a
    more appropriate benchmark than the Index for purposes of evaluating the
    performance of the Trust; and/or 2) that a Class of shares of the Trust
    other than Class A is most appropriate for use in calculating the
    Performance Adjustment. After ten days' written notice to the Manager, a
    successor index (the "Successor Index") may be substituted for the Index
    in prospectively calculating the Performance Adjustment; and/or a
    different Class of shares may be substituted in calculating the
    Performance Adjustment. However, the calculation of that portion of the
    Performance Adjustment attributable to any portion of the performance
    period prior to the adoption of the Successor Index will still be based
    upon the Trust's performance compared to the Index. The use of a different
    Class of shares for purposes of calculating the Performance Adjustment
    shall apply to the entire performance period so long as such Class was
    outstanding at the beginning of such period. In the event that such Class
    of shares was not outstanding for all or a portion of the Performance
    Period, it may only be used in calculating that portion of the Performance
    Adjustment attributable to the period during which such Class was
    outstanding and any prior portion of the Performance Period shall be
    calculated using Class A shares.

C)  The Basic Fee is equal to [insert basic fee] per annum of the Fund's
    average daily net assets.

D)  The Performance Adjustment consists of an adjustment to the monthly
    Basic Fee to be made by applying a Performance Adjustment rate to the
    average net assets of the Trust over the Performance Period. The resulting
    dollar figure will be added to or subtracted from the Basic Fee depending
    on whether the Trust experienced better or worse performance than the
    Index.

The Performance Adjustment rate is [0.01%] [0.02% for Pioneer Mid Cap
Growth Fund] per annum for each percentage point rounded to the nearer
point (the higher point if exactly one-half point) that the Trust's
investment performance for the period was better or worse than the record
of the Index as then constituted. The maximum Performance Adjustment is
0.10% [0.20% for Pioneer Mid Cap Growth Fund] per annum. In addition, as
the Trust's average daily net assets over the Performance Period may differ
substantially from the Trust's average daily net assets during the current
year, the Performance Adjustment may be further adjusted to the extent
necessary to insure that the total adjustment to the Basic Fee on an
annualized basis does not exceed 0.10% [0.20% for Pioneer Mid Cap Growth
Fund].

The Performance Period shall consist of a rolling 36-month period
consisting of the most recently completed month and the previous 35 months.

The Trust's investment performance will be measured by comparing the (i)
opening net asset value of one Class A share of the Trust on the first
business day of the performance period with (ii) the closing net asset
value of one Class A share of the Trust as of the last business day of such
period. In computing the investment performance of the Trust and the
investment record of the Index, distributions of realized capital gains,
the value of capital gains taxes per share paid or payable on undistributed
realized long-term capital gains accumulated to the end of such period and
dividends paid out of investment income on the part of the Trust, and all
cash distributions of the companies whose stock comprise the Index, will be
treated as reinvested in accordance with Rule 205-1 or any other applicable
rule under the Investment Advisers Act of 1940, as the same from time to
time may be amended.

The computation of the Performance Adjustment will not be cumulative. A
positive fee adjustment will apply even though the performance of the Trust
over some period of time shorter than the performance period has been
behind that of the Index, and, conversely, a negative fee adjustment will
apply for the month even though the performance of the Trust over some
period of time shorter than the performance period has been ahead of that
of the Index.

E)  An appropriate percentage (based on the number of days in the current
    month) of the annual Performance Adjustment rate shall be multiplied by
    the average of the net assets of the Trust (computed in the manner set
    forth in the Declaration of Trust of the Trust adjusted as provided above,
    if applicable) determined as of the close of business on each business day
    throughout the performance period. The resulting dollar amount is added to
    or deducted from the Basic Fee.

9.  The Management Fee payable hereunder shall be computed daily and paid
    monthly in arrears. In the event of the termination of this Agreement, the
    Basic Fee then in effect shall be computed on the basis of the period
    ending on the last business day on which this Agreement is in effect
    subject to a pro rata adjustment based on the number of days elapsed in
    the current month as a percentage of the total number of days in such
    month. The amount of any Performance Adjustment to the Basic Fee will be
    computed on the basis of and applied to net assets averaged over the
    36-month period ending on the last business day on which this Agreement is
    in effect.

10. The Manager may from time to time agree not to impose all or a portion
    of its fee otherwise payable hereunder (in advance of the time such fee or
    a portion thereof would otherwise accrue) and/or undertake to pay or
    reimburse the Trust for all or a portion of its expenses not otherwise
    required to be borne or reimbursed by the Manager. Any such fee reduction
    or undertaking may be discontinued or modified by the Manager at any time.

11. It is understood that the Manager may employ one or more sub-investment
    advisers (each a "Subadviser") to provide investment advisory services to
    the Trust by entering into a written agreement with each such Subadviser;
    provided, that any such agreement first shall be approved by the vote of a
    majority of the Trustees, including a majority of the Trustees who are not
    "interested persons" (as defined in the 1940 Act) of the Trust, the
    Manager or any such Subadviser, and otherwise approved in accordance with
    the requirements of the 1940 Act or an exemption therefrom. The authority
    given to the Manager in Sections 1 through 13 hereof may be delegated by
    it under any such agreement; provided, that any Subadviser shall be
    subject to the same restrictions and limitations on investments and
    brokerage discretion as the Manager. The Trust agrees that the Manager
    shall not be accountable to the Trust or the Trust's shareholders for any
    loss or other liability relating to specific investments directed by any
    Subadviser, even though the Manager retains the right to reverse any such
    investment because, in the event a Subadviser is retained, the Trust and
    the Manager will rely almost exclusively on the expertise of such
    Subadviser for the selection and monitoring of specific investments.

12. The Manager will not be liable for any error of judgment or mistake of
    law or for any loss sustained by reason of the adoption of any investment
    policy or the purchase, sale, or retention of any security on the
    recommendation of the Manager, whether or not such recommendation shall
    have been based upon its own investigation and research or upon
    investigation and research made by any other individual, firm or
    corporation, but nothing contained herein will be construed to protect the
    Manager against any liability to the Trust or its shareholders by reason
    of willful misfeasance, bad faith or gross negligence in the performance
    of its duties or by reason of its reckless disregard of its obligations
    and duties under this Agreement.

13. Nothing in this Agreement will in any way limit or restrict the Manager
    or any of its officers, directors, or employees from buying, selling or
    trading in any securities for its or their own accounts or other accounts.
    The Manager may act as an investment adviser to any other person, firm or
    corporation, and may perform management and any other services for any
    other person, association, corporation, firm or other entity pursuant to
    any contract or otherwise, and take any action or do any thing in
    connection therewith or related thereto; and no such performance of
    management or other services or taking of any such action or doing of any
    such thing shall be in any manner restricted or otherwise affected by any
    aspect of any relationship of the Manager to or with the Trust or deemed
    to violate or give rise to any duty or obligation of the Manager to the
    Trust except as otherwise imposed by law. The Trust recognizes that the
    Manager, in effecting transactions for its various accounts, may not
    always be able to take or liquidate investment positions in the same
    security at the same time and at the same price.

14. In connection with purchases or sales of securities for the account of
    the Trust, neither the Manager nor any of its directors, officers or
    employees will act as a principal or agent or receive any commission
    except as permitted by the 1940 Act. The Manager shall arrange for the
    placing of all orders for the purchase and sale of securities for the
    Trust's account with brokers or dealers selected by the Manager. In the
    selection of such brokers or dealers and the placing of such orders, the
    Manager is directed at all times to seek for the Trust the most favorable
    execution and net price available except as described herein. It is also
    understood that it is desirable for the Trust that the Manager have access
    to supplemental investment and market research and security and economic
    analyses provided by brokers who may execute brokerage transactions at a
    higher cost to the Trust than may result when allocating brokerage to
    other brokers on the basis of seeking the most favorable price and
    efficient execution. Therefore, the Manager is authorized to place orders
    for the purchase and sale of securities for the Trust with such brokers,
    subject to review by the Trust's Trustees from time to time with respect
    to the extent and continuation of this practice. It is understood that the
    services provided by such brokers may be useful to the Manager in
    connection with its or its affiliates' services to other clients. In
    addition, subject to the Manager's obligation to seek the most favorable
    execution and net price available, the Manager may consider the sale of
    the Trust's shares in selecting brokers and dealers.

15. On occasions when the Manager deems the purchase or sale of a security
    to be in the best interest of the Trust as well as other clients, the
    Manager may, to the extent permitted by applicable laws and regulations,
    aggregate the securities to be sold or purchased in order to obtain the
    best execution and lower brokerage commissions, if any. In such event,
    allocation of the securities so purchased or sold, as well as the expenses
    incurred in the transaction, will be made by the Manager in the manner it
    considers to be the most equitable and consistent with its fiduciary
    obligations to the Trust and to such clients.

16. This Agreement shall become effective on the date hereof and shall
    remain in force until December 31, 2004 and from year to year thereafter,
    but only so long as its continuance is approved in accordance with the
    requirements of the 1940 Act or an exemption therefrom, subject to the
    right of the Trust and the Manager to terminate this contract as provided
    in Section 17 hereof.

17. Either party hereto may, without penalty, terminate this Agreement by
    vote of its Board of Trustees or Directors, as the case may be, or by vote
    of a "majority of the outstanding voting securities" (as defined in the
    1940 Act) of the Trust or the Manager, as the case may be, and the giving
    of 60 days' written notice to the other party.

18. This Agreement shall automatically terminate in the event of its
    assignment. For purposes of this Agreement, the term "assignment" shall
    have the meaning given it by Section 2(a)(4) of the 1940 Act.

19. The Trust agrees that in the event that neither the Manager nor any of
    its affiliates acts as an investment adviser to the Trust, the name of the
    Trust will be changed to one that does not contain the name "Pioneer" or
    otherwise suggest an affiliation with the Manager.

20. The Manager is an independent contractor and not an employee of the
    Trust for any purpose. If any occasion should arise in which the Manager
    gives any advice to its clients concerning the shares of the Trust, the
    Manager will act solely as investment counsel for such clients and not in
    any way on behalf of the Trust.

21. This Agreement states the entire agreement of the parties hereto, and
    is intended to be the complete and exclusive statement of the terms
    hereof. It may not be added to or changed orally and may not be modified
    or rescinded except by a writing signed by the parties hereto and in
    accordance with the 1940 Act, when applicable.

22. This Agreement and all performance hereunder shall be governed by and
    construed in accordance with the laws of The Commonwealth of
    Massachusetts.

23. Any term or provision of this Agreement which is invalid or
    unenforceable in any jurisdiction shall, as to such jurisdiction, be
    ineffective to the extent of such invalidity or unenforceability without
    rendering invalid or unenforceable the remaining terms or provisions of
    this Agreement or affecting the validity or enforceability of any of the
    terms or provisions of this Agreement in any other jurisdiction.

24. This Agreement may be executed simultaneously in two or more
    counterparts, each of which shall be deemed an original, but all of which
    together shall constitute one and the same instrument.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their duly authorized officers and their seal to be hereto
affixed as of the day and year first above written.

Portfolio transaction policies

All orders for the purchase or sale of portfolio securities are placed on
behalf of each fund by Pioneer pursuant to authority contained in the
fund's management contract. Pioneer seeks to obtain the best execution on
portfolio trades. The price of securities and any commission rate paid are
always factors, but frequently not the only factors, in judging best
execution. In selecting brokers or dealers, Pioneer considers various
relevant factors, including, but not limited to, the size and type of the
transaction; the nature and character of the markets for the security to be
purchased or sold; the execution efficiency, settlement capability and
financial condition of the dealer; the dealer's execution services rendered
on a continuing basis; and the reasonableness of any dealer spreads.
Transactions in non-U.S. equity securities are executed by broker-dealers
in non-U.S. countries in which commission rates may not be negotiable (as
such rates are in the U.S.).

Pioneer may select broker-dealers that provide brokerage and/or research
services to a fund and/or other investment companies or other accounts
managed by Pioneer. In addition, consistent with Section 28(e) of the
Exchange Act, if Pioneer determines in good faith that the amount of
commissions charged by a broker-dealer is reasonable in relation to the
value of the brokerage and research services provided by such broker, the
fund may pay commissions to such broker-dealer in an amount greater than
the amount another firm may charge. Such services may include advice
concerning the value of securities; the advisability of investing in,
purchasing or selling securities; the availability of securities or the
purchasers or sellers of securities; providing stock quotation services,
credit rating service information and comparative fund statistics;
furnishing analyses, electronic information services, manuals and reports
concerning issuers, industries, securities, economic factors and trends,
portfolio strategy, and performance of accounts and particular investment
decisions; and effecting securities transactions and performing functions
incidental thereto (such as clearance and settlement). Pioneer maintains a
listing of broker-dealers who provide such services on a regular basis.
However, because many transactions on behalf of a fund and other investment
companies or accounts managed by Pioneer are placed with broker-dealers
(including broker-dealers on the listing) without regard to the furnishing
of such services, it is not possible to estimate the proportion of such
transactions directed to such dealers solely because such services were
provided. Pioneer believes that no exact dollar value can be calculated for
such services.

The research received from broker-dealers may be useful to Pioneer in
rendering investment management services to any of the funds as well as
other investment companies or other accounts managed by Pioneer, although
not all such research may be useful to any of the funds. Conversely, such
information provided by brokers or dealers who have executed transaction
orders on behalf of such other accounts may be useful to Pioneer in
carrying out its obligations to any of the funds. The receipt of such
research has not reduced Pioneer's normal independent research activities;
however, it enables Pioneer to avoid the additional expenses which might
otherwise be incurred if it were to attempt to develop comparable
information through its own staff.

In circumstances where two or more broker-dealers offer comparable prices
and executions, preference may be given to a broker-dealer which has sold
shares of a fund as well as shares of other investment companies managed by
Pioneer. This policy does not imply a commitment to execute all portfolio
transactions through all broker-dealers that sell shares of the fund.

None of the funds used any brokers affiliated with Pioneer during its most
recently completed fiscal year in connection with its portfolio
transactions.

DEALER ADVISORY PERFORMANCE FEE BENCHMARK CHANGES:

Pioneer Fund, Pioneer Value Fund, Pioneer Mid Cap Value Fund, Pioneer Mid Cap
Growth Fund and Pioneer Growth Shares


February 2003

This letter is to inform you that the Board of Trustees approved changes in
the performance fee benchmarks for five Pioneer funds: Pioneer Fund, Pioneer
Value Fund, Pioneer Mid Cap Value Fund, Pioneer Mid Cap Growth Fund and Pioneer
Growth Shares. The decision was made after it was determined that the current
performance fee benchmarks were obsolete or no longer the most appropriate in
light of the fund's investment style. The table below outlines the current and
proposed benchmarks.

FUND                    CURRENT PERFORMANCE        PROPOSED PERFORMANCE
                        FEE BENCHMARK              FEE BENCHMARK
Pioneer Fund            Lipper Growth & Income     S&P 500 Index
                        Fund Index
Pioneer Value Fund      Lipper Growth & Income     Russell 1000 Value Index
                        Fund Index
Pioneer Mid Cap         Lipper Growth Fund Index   Russell Midcap Value Index

Pioneer Mid Cap         S&P 400 Index              Russell Midcap Growth Index
Growth Fund
Pioneer Growth Shares   Russell 1000 Index         Russell 1000 Growth Index

Pioneer believes that the proposed change in performance benchmarks offers
significant potential benefits to the funds and their shareowners. We believe
that these changes, if approved by shareowners, will have a positive effect on
the funds for the following reasons:

o A portfolio manager's goal is to achieve the fund's objective as referenced in
  the prospectus. We believe that using the same index for purposes of
  calculating the performance fee as that used as a market benchmark
  appropriately aligns a portfolio manager's goals with that of the fund.

o We believe the best way to help a manager ensure style consistency is to use a
  market benchmark that is representative of a fund's characteristics and
  investment style.

o Market indices' characteristics are readily available to portfolio managers
  and are less susceptible to changes that may be experienced with Lipper
  indices.




A meeting will be held on April 17, 2003 for shareowners to vote on the
aforementioned proposal as well as several others that are highlighted below:

o A proposal to elect eight trustees to the Board

o A proposal to approve a new management contract between the fund and Pioneer
  Investment Management, Inc., the fund's investment adviser, indicating the new
  benchmark and amending certain expense provisions applicable to the fund

o A proposal to approve a policy allowing Pioneer and the fund's board of
  trustees to appoint or terminate subadvisers and approve amendments to
  subadvisory agreements without shareowner approval

o A proposal to approve changes to fundamental investment restrictions and
  policies which would increase the fund's flexibility to respond to new
  developments and changing trends in the marketplace, thus making the funds
  more competitive among their peers.

A complete explanation of each of the proposals up for a vote can be found
in the enclosed proxy statement. We hope this information is helpful. If you
have questions regarding this matter, please call our Sales Desk at
800-622-9876. We appreciate your past support and look forward to continued
mutual success.

For more information about any Pioneer fund, including charges and expenses
call Pioneer and request a prospectus. Investors should read it carefully before
investing or sending money.

WHY IS PIONEER RECOMMENDING CHANGING THE CURRENT PERFORMANCE FEE BENCHMARKS?

Pioneer believes that the proposed change in performance benchmarks offers
potential benefits to the funds and their shareowners. We believe that these
changes, if approved by shareowners, will have a positive effect on the funds
for the following reasons:

o        For three of the funds, the current indices used by the funds are no
         longer the primarily indices published by Lipper and are not published
         daily in major newspapers. In the case of the other two funds, changes
         in the investment style of the fund since a performance fee was
         initially adopted has resulted in the current indices not being the
         most representative of the funds' investment style.

o        The funds' Trustees believe that it was desirable to have a benchmark
         index that is readily available to shareholders so that shareholders
         are in a better position to evaluate the fund's performance and is
         aligned with the manner in which the fund is managed and the basis upon
         which Pioneer provides incentive compensation to its portfolio
         managers. The Trustees also believe that a performance fee remains an
         effective means of aligning the interest of Pioneer with the interest
         of shareholders.

o        The Trustees also considered alternative indices, including peer group
         indices such as the Lipper indices and concluded that the alternative
         indices would not be as effective in achieving the goal of the
         performance fee.

WILL THE FUND EXPENSES GOING FORWARD BE ADJUSTED TO REFLECT THE INCREASE OR
DECREASE IN THE NEW HISTORICAL PRO FORMA EXPENSES?

No. The historical comparisons are not necessarily indicative of the relative
fees that would result from future performance. The comparisons are provided
only for historical illustrative purposes and will not be used to compensate
Pioneer Investments for prior aggregate increase or decrease fee differences.

WHAT IS THE SUBADVISORY PROPOSAL?

The proposed policy would permit Pioneer to appoint subadvisers, to enter into
subadvisory agreements and to amend or terminate existing subadvisory agreements
without further shareowner approval. Any such appointment or termination would
be subject to prior approval of the Board of Trustees, including a majority of
the Independent Trustees.






WHAT ARE THE PROPOSED AMENDMENTS TO THE FUND'S FUNDAMENTAL INVESTMENT
RESTRICTIONS AND POLICIES?

You are being asked to approve a policy eliminating or amending various
investment restrictions and policies. The Trustees recommend that these changes
be made to simplify and modernize the funds' fundamental investment restrictions
and conform them to restrictions adopted by other Pioneer funds. These changes
will increase the funds' flexibility to respond to new developments and changing
trends in the market place, thus making the funds more competitive among their
peers.

This proposal sections contains specific restriction and policy information that
cannot be generally summarized. We recommend that all shareowners review the
entire proxy.

WHAT IS THE RECORD DATE THAT IS TO BE USED TO DETERMINE IF I AM ELIGIBLE TO
VOTE?

The record date for this proxy includes shareowners of record as of the close of
business on February 14, 2003.

HOW CAN I VOTE MY SHARES?

There are three ways to vote your shares - by phone, by Internet or by mail. If
you vote by phone or Internet, please do not return your proxy card(s).

WHEN AND WHERE IS THE SHAREOWNER MEETING TAKING PLACE?

LLP, 60 State Street, 26th Floor, Boston, Massachusetts on Thursday, April 17,
2003, at 1:00 p.m., Boston time.
