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,  Massachusetts 02109 at 1:00

notice of special meeting to shareholders.

     This  proxy  statement  and the  enclosed  proxy  card are being  mailed to
shareholders  on or about  February [17],  2003.  Each fund's most recent annual
report was previously mailed to the fund's shareholders.

                             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 proxies,  unless
revoked  before or at the  meeting,  will be voted  according  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:

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

|X|  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;

|X|  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;

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

     |X|  brokerage and soft dollar arrangements of the fund,

     |X|  the utilization of any line of credit, and

     |X|  "as of" gain/loss activity of the fund;

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

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

|X|  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,  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
the  number  of  meetings  indicated  below.  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.

During  any  fund's  most  recently  completed fiscal year, none of the trustees
or any nominee for  election as a trustee of a fund  engaged in the  purchase or
sale  of  securities  of  Pioneer,   UniCredito  Italiano  S.p.A.   ("UniCredito
Italiano")  or any other  entity in a control  relationship  to  Pioneer or PFD,
[except  that Mr.  Cogan  purchased  less  than $ of  securities  of  UniCredito
Italiano at market prices].

MATERIAL  RELATIONSHIPS  OF  THE  INDEPENDENT  TRUSTEES.   For  purposes  of the
statements below:

o    the IMMEDIATE  FAMILY  MEMBERS of any person are their spouse,  children in
     the  person's  household  (including  step and adoptive  children)  and any
     dependent of the person.

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

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

     As of December 31, 2002, none of the Independent Trustees, nor any of their
immediate family members,  beneficially  owned any securities issued by Pioneer,
UniCredito Italiano or any other entity in a control  relationship to Pioneer or
PFD or any person in a control relationship to PFD.

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

     During the past five years,  none of the Independent  Trustees,  nor any of
their immediate family members,  had an interest in a transaction or a series of

transactions,  in which the aggregate  amount involved  exceeded  $60,000 and to
which any of the following were a party (each a "fund related party"):

        o       the funds               o       an officer of Pioneer or PFD
        o       an officer of the funds o       an officer of PFD
        o       a related fund          o       any affiliate of Pioneer or PFD
        o       an officer of any       o       an officer of any such affiliate
                related fund
        o       Pioneer or PFD

     During the calendar years 2001 and 2002, none of the Independent  Trustees,
nor any of their immediate family members,  had any  relationship  (the value of
which exceeded $60,000) with any fund related party, including,  but not limited
to, relationships arising out of (i) the payment for property and services, (ii)
the  provision of legal  services,  (iii) the  provision of  investment  banking
services  (other  than as a member of the  underwriting  syndicate)  or (iv) the
provision of consulting services,  except that Mr. West, an Independent Trustee,
is Of Counsel to  Sullivan  &  Cromwell  and acts as counsel to the  Independent
Trustees and the Independent  Trustees of the other Pioneer Funds. The aggregate
compensation  paid to  Sullivan  & Cromwell  by the funds and the other  Pioneer
Funds exceeded $60,000 in each of 2001 and 2002.

     During the calendar years 2001 and 2002, none of the Independent  Trustees,
nor any of their  immediate  family  members,  served  as a member of a board of
directors on which an officer of any of the following  entities also serves as a
director:

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

     None of the fund's trustees or officers has any arrangement  with any other
person  pursuant  to which  that  trustee  or  officer  serves  on the  board of
trustees.  During  the  calendar  years 2001 and 2002,  none of the  Independent
Trustees, nor any of their immediate family members, had any position, including
as an officer, employee, director or partner, with any of the following:

        o       the funds               o       any affiliated person of the
                                                funds
        o       any related fund        o       UniCredito Italiano
        o       Pioneer                 o       any other entity in a control
        o       PFD                             relationship to the funds

                      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  contracts 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  (the  "Benchmark  Index") as
follows:

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


Because  of  the  reasons  discussed  in  this proxy  statement,  the  board  of
trustees  concluded  that  changing each fund's  Benchmark  Index is in the best
interests of 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:

     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 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:

     o    Performance-based  compensation  continues to be a desirable method to
          reward good investment performance and penalize bad performance.
     o    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.
     o    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.
     o    The board of trustee 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.
     o    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.
     o    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 generally 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:

     o    Performance-based  compensation  continues to be a desirable method to
          reward good investment performance and penalize bad performance.
     o    The Lipper  Growth and Income Index and the Lipper Growth Index are no
          longer  widely  generally  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.
     o    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  100 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.
     o    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.
     o    The board of trustee 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.
     o    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  than the actual  fee that  Pioneer  received  or the fee that
          would  have  resulting  using  alternative  peer group  indexes.  This
          historical  comparison is not  necessarily  indicative of the relative
          fees that would result from future performance.

     PIONEER FUND.  The fund's current  Benchmark  Index - the Lipper Growth and
Income Index - is no longer generally 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   shareholders  and  Pioneer.   Specifically,   Pioneer
recommended  this change -- and the trustees  determined to recommend the change
to shareholders -- based on the following:

     o    Performance-based  compensation  continues to be a desirable method to
          reward good investment performance and penalize bad performance.
     o    The  Lipper  Growth  and Income  Index is no longer  widely  generally
          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.
     o    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.
     o    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.
     o    The board of trustee 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.
     o    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  resulting  using
          alternative  peer group  indexes.  This  historical  comparison is not
          necessarily  indicative  of the  relative  fees that would result from
          future performance.

     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 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:

     o    Performance-based  compensation  continues to be a desirable method to
          reward good investment performance and penalize bad performance.
     o    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
          Index would better align Pioneer's economic incentives with the manner
          in which the fund is managed and consequently the economic interest of
          shareholders.
     o    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.
     o    The board of trustee 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.
     o    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.
     o    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 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 30],
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
adopted  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.

that would have been paid under the proposed contract and the maximum, basic and
minimum fee rates and amount actually paid under the existing contract. Also set
forth below is a  comparative  fee table showing the amount of fees and expenses
paid by the fund under the existing  contract as a percentage  of average  daily
net assets,  using the  maximum,  basic and minimum  management  fee rates,  the
actual  management  fee paid,  and the amount of fees and expenses  shareholders
would have paid if the proposed contract had been in effect.  For information on

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  arrangements  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 a 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,   bylaws,   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 other Pioneer mutual funds when selecting  brokers and dealers
to execute the fund's securities transactions.

MISCELLANEOUS

     If approved,  the proposed  contract  will become  effective on [April 30,]
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

     For additional information concerning the management,  ownership structure,
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 out perform 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:
     o    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.
     o    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.
     o    The board of trustee 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.
     o    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.
     o    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.
     o    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:
     o    The Lipper  Growth and Income Index and the Lipper Growth Index are no
          longer  widely  generally  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.
     o    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.
     o    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.
     o    The board of trustee 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.
     o    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  than the actual  fee that  Pioneer  received  or the fee that
          would  have  resulting  using  alternative  peer group  indexes.  This
          historical  comparison is not  necessarily  indicative of the relative
          fees that would result from future performance.
     o    The  trustees  also  considered  the  statistical  correlation  of the
          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:
     o    The  Lipper  Growth  and Income  Index is no longer  widely  generally
          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.
     o    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.
     o    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.
     o    The board of trustee 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.
     o    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.
     o    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:
     o    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.
     o    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.
     o    The board of trustee 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 respective fund's
          investment style and risk characteristics.
     o    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.
     o    The  trustees  also  considered  the  statistical  correlation  of the
          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.
     o    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:

     o    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;
     o    the fee charged by Pioneer for investment  advisory and administrative
          services, as well as other compensation received by PFD and PIMSS;
     o    each fund's projected total operating expenses;
     o    the  investment  performance,  fees and total  expenses of  investment
          companies  with similar  objectives  and  strategies  managed by other
          investment advisers;
     o    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
     o    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 fee 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 its  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 the 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, the
fund 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.

                                                  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 it invests.

                                                  exceeding 10% of the fund's
                                                  total assets (including the
                                                  amount borrowed) taken at
                                                  market value.


     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)].  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. 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.

                                                  regulations thereunder.

               Pioneer Mid Cap Value Fund         The fund may not invest in
                                                  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.

     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.

     All of the funds are diversified.  The 1940 Act requires that "diversified"
funds adopt a fundamental policy regarding this status.  This change is designed
to promote  uniformity  among  Pioneer  funds and afford  each fund the  maximum
flexibility to comply with the requirements of the 1940 Act and  interpretations
thereof as they may change from time to time.

     None of the funds concentrate  their investments in a single industry.  The
1940  Act  requires   that  a  fund  adopt  a   fundamental   policy   regarding
concentration. This change is designed to promote uniformity among Pioneer funds
and afford each fund the maximum  flexibility to comply with the requirements of
the 1940 Act and interpretations thereof as they may change from time to time.

                                                  thereby.


     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                               short sales of securities.


     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.

                                                                                     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 sales  "against-the-box",  the fund owns or has the right to acquire the
security sold short.

   CONTROL


     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.

                                                  estate investment trust,
                                                  provided that such trust shall
                                                  not be permitted to invest in
                                                  real estate or interests in

                                                  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.

                                                  call options on securities
                                                  indices to manage cash flow
                                                  and to attempt to remain fully
                                                  invested in the stock market,
                                                  instead of or in addition to
                                                  buying and selling stocks. The
                                                  fund may also purchase these
                                                  options in order to hedge
                                                  against risks of market-wide
                                                  price fluctuations.

                                                  Options on securities indices
                                                  are similar to options on
                                                  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
                                                  obligations, corporate

                                                  obligations, in each case
                                                  rated or issued by companies
                                                  with similar securities

                                                  or, if unrated, of comparable
                                                  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. 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.

                                                  securities of any one issuer;
                                                  provided, however, that this
                                                  restriction does not apply to
                                                  cash items and U.S. government
                                                  securities; (c) Write (sell)

                                                  exceeding 5% of its assets,
                                                  calls, puts, straddles,

                                                  thereof; or (d) Invest more
                                                  than 5% of its total assets in
                                                  financial instruments that are
                                                  used for non-hedging purposes
                                                  and which have a leverage
                                                  effect.


     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.

PIONEER FUND

PIONEER GROWTH SHARES


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 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 [ ], professional proxy solicitors, who will be paid fees and expenses of
approximately  $[ ] 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
                  Directors 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

                                    EXHIBIT B

                      FORM OF PROPOSED MANAGEMENT CONTRACT



         THIS AGREEMENT dated as of this 31st day of March, 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 objectives 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 objectives, 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, 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.      (a) 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 April 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 through out 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.
