Class A, Class B and Class C Shares
Prospectus
January ____, 1996

Pioneer Real Estate Shares (the "Fund") is a non-diversified open-end investment
company  seeking  primarily  long-term  growth of capital.  Current  income is a
secondary objective.  The Fund will seek to achieve its investment objectives by
investing at least 75% of its total assets in a portfolio  consisting  primarily
of equity  securities  of real  estate  investment  trusts and other real estate
industry companies.
    

   The Fund may also invest up to 25% of its total assets in debt  securities of
real  estate  industry  companies,  mortgage-backed  securities  and  short-term
investments. In pursuit of its objectives, the Fund may employ active management
techniques  (including  futures  and  options)  in an  attempt  to  hedge  risks
associated with the Fund's investments in real estate equity  securities.  There
is,  of  course,  no  assurance  that  the  Fund  will  achieve  its  investment
objectives.

   FUND  RETURNS AND SHARE PRICES  FLUCTUATE  AND THE VALUE OF YOUR ACCOUNT UPON
REDEMPTION MAY BE MORE OR LESS THAN YOUR PURCHASE PRICE.  SHARES IN THE FUND ARE
NOT DEPOSITS OR OBLIGATIONS  OF, OR GUARANTEED OR ENDORSED BY, ANY BANK OR OTHER
DEPOSITORY INSTITUTION,  AND THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
DEPOSIT  INSURANCE  CORPORATION,   THE  FEDERAL  RESERVE  BOARD,  OR  ANY  OTHER
GOVERNMENT  AGENCY.  INVESTMENTS IN SECURITIES OF REAL ESTATE INDUSTRY COMPANIES
ENTAIL  RISKS IN ADDITION TO THOSE  CUSTOMARILY  ASSOCIATED  WITH  INVESTING  IN
SECURITIES  IN GENERAL.  THE FUND IS INTENDED FOR  INVESTORS  WHO CAN ACCEPT THE
RISKS ASSOCIATED WITH ITS INVESTMENTS AND MAY NOT BE SUITABLE FOR ALL INVESTORS.
SEE "INVESTMENT OBJECTIVES AND POLICIES" FOR A DISCUSSION OF THESE RISKS.

I. EXPENSE INFORMATION

   
This table is designed to help you understand the charges and expenses that you,
as a shareholder,  will bear directly or indirectly when you invest in the Fund.
The  table  reflects  annual  operating  expenses  based on the  actual  Class A
expenses  incurred for the fiscal period ended December 31, 1994. Other expenses
for Class B and Class C shares  are based on  estimated  amounts  for the fiscal
period ended December 31, 1994 had such shares been outstanding.

Shareowner Transaction Expenses:                   Class A  Class B+  Class C+
 Maximum Initial Sales Charge on
    Purchases (as a percentage of offering price)   5.75%(1)  None      None
 Maximum Sales Charge on Reinvestment
    of Dividends                                    None      None      None
 Maximum Deferred Sales Charge                      None(1)   4.00%     1.00%
    (as a percentage of original purchase
     price or redemption proceeds, as 
     applicable)
 Redemption Fee(2)                                  None      None      None
 Exchange Fee                                       None      None      None

Annual Operating Expenses (As a Percentage of Net Assets):
 Management Fee (after expense limitation)3         0.42%     0.42%     0.42%
 12b-1 Fees                                         0.25%     1.00%     1.00%
 Other Expenses (including accounting and transfer
    agent fees, custodian fees and printing expenses)
                                                    1.08%     1.08%     1.08%
 Total Operating Expenses 
    (after expense limitation): 3                   1.75%     2.50%     2.50%

+ Class B and Class C shares will first be offered on January ____, 1996.
    


 (1) Purchases of $1 million or more and certain  purchases by participants in a
"Group Plan" (as described under "How to Purchase Shares") are not subject to an
initial sales charge. A contingent  deferred sales charge of 1.00% may, however,
be charged on  redemptions  by such accounts of shares held less than 12 months,
as further described under "Redemptions and Repurchases" in this Prospectus.

 (2) Separate fees (currently $10 and $20,  respectively)  apply to domestic and
international bank wire transfers of redemption proceeds.

   
 (3)  Pioneering  Management  Corporation  ("PMC")  has  agreed  not to impose a
portion of its management fee and to make other arrangements,  if necessary,  to
the extent  nedessary to limit the  operating  expenses of the Class A shares of
the Fund to 1.75% of its  average  daily net assets;  the  portion of  fund-wide
expenses  attributable  to Class B or Class C shares will be reduced only to the
extent they are reduced for Class A shares.  This  agreement  is  voluntary  and
temporary  and may be revised or  terminated at any time. In the absence of this
agreement, annual operating expenses would be as follows:

Annual Operating Expenses Absent Expense Limitation 
(As a Percentage of Net Assets )
Management Fee                        1.00%         1.00%         1.00%
Total Operating Expenses              2.33%         3.08%         3.08%
    


Example:

   You  would  pay the  following  fees and  expenses  on a  $1,000  investment,
assuming a 5% annual return and constant expenses, with or without redemption at
the end of each time period:

                                      -2-

                               One Year   Three Years   Five Years    Ten Years

Class A Shares                   $17          $ 52         $ 90          $195
Class B Shares*
- --Assuming complete
  redemption at end of period    $66          $109         $155          $268
- --Assuming no redemption         $26          $ 79         $135          $268
Class C Shares**
- --Assuming complete
  redemption at end of period    $36          $ 79         $135          $287
- --Assuming no redemption         $26          $ 79         $135          $287

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

*    Class B shares  convert  to  Class A shares  eight  years  after  purchase;
     therefore, Class A expenses are used after year eight.
**   Class C shares redeemed during the first year after purchase are subject to
     a 1% Contingent Deferred Sales Charge ("CDSC").
    

   The example above assumes reinvestment of all dividends and distributions and
that the percentage amounts listed under "Annual Operating  Expenses" remain the
same each year.

   The example is designed  for  information  purposes  only,  and should not be
considered a  representation  of past or future expenses or return.  Actual fund
expenses and return vary from year to year and may be higher or lower than those
shown.

   
For further information regarding management fees, 12b-1 fees and other expenses
of the Fund,  including  information  regarding  the basis  upon  which fees and
expenses are reduced or reallocated, see "Management of the Fund," "Distribution
Plans" and "How to Buy Fund Shares" in this  Prospectus  and  "Management of the
Fund" and  "Underwriting  Agreement and Distribution  Plans" in the Statement of
Additional  Information.  The  Fund's  payment  of a  12b-1  fee may  result  in
long-term  shareholders  paying more than the economic equivalent of the maximum
initial sales charge  permitted under the Rules of Fair Practice of the National
Association of Securities Dealers, Inc. ("NASD").

   The maximum  sales charge is reduced on  purchases  of  specified  amounts of
Class A shares and the value of shares  owned in other  Pioneer  mutual funds is
taken into account in determining the applicable  initial sales charge. See "How
to Buy Fund  Shares." No sales charge is applied to exchanges of shares of other
publicly available Pioneer mutual funds. See "How to Exchange Fund Shares."

III. INVESTMENT OBJECTIVES AND POLICIES

   The  Fund's  primary  investment  objective  is to seek  long-term  growth of
capital.  Current income is a secondary investment  objective.  The Fund pursues
these  objectives  by  investing  in  a  non-diversified   portfolio  consisting
primarily of equity  securities of real estate  investment trusts and other real
estate  industry  companies and, to a lesser extent,  in debt securities of such
companies and in mortgage-backed securities.

   Under  normal  circumstances,  at least 75% of the  Fund's  total  assets are
invested in equity  securities of real estate  investment  trusts  ("REITs") and
other real estate industry companies. For purposes of the Fund's investments,  a
"real  estate  industry  company" is a company  that derives at least 50% of its
gross  revenues  or net  profits  from  either (a) the  ownership,  development,
construction,  financing,  management  or  sale  of  commercial,  industrial  or
residential  real estate or (b) products or services  related to the real estate
industry like building supplies or mortgage servicing.  The equity securities of
real estate  industry  companies in which the Fund will invest consist of common
stock,  shares of  beneficial  interest  of real  estate  investment  trusts and
securities with common stock  characteristics,  such as preferred stock and debt
securities convertible into common stock ("Real Estate Equity Securities").

   The Fund may also invest up to 25% of its total assets in (a) debt securities
of real estate  industry  companies,  (b)  mortgage-backed  securities,  such as
mortgage  pass-through  certificates,  real estate mortgage  investment  conduit
("REMIC") certificates and collateralized  mortgage obligations ("CMOs") and (c)
short-term investments (as listed below). See "Other Eligible Investments."

   
   In pursuit of its objectives,  the Fund may employ certain active  management
techniques  including  options on  securities  indices and futures  contracts on
securities and indices and options on such futures  contracts.  These techniques
may be employed in an attempt to hedge  interest rate or other risks  associated
with the Fund's portfolio securities.  See Appendix A for a description of these
investment practices and associated risks.

   For temporary defensive purposes, the Fund may invest up to 100% of its total
assets in  short-term  investments  (as listed  below).  The Fund will  assume a
temporary defensive posture only when economic and other factors affect the real
estate  industry  market  to  such an  extent  that  PMC  believes  there  to be
extraordinary  risks in  being  substantially  invested  in Real  Estate  Equity
Securities.

   As to any  specific  investment  in  Real  Estate  Equity  Securities,  PMC's
analysis will focus on evaluating the  fundamental  value of an enterprise.  The
Fund will purchase  securities  for its portfolio  when, in the judgment of PMC,
their market price appears to be less than their  fundamental value and/or which
offer a high level of current income consistent with reasonable investment risk.
In selecting specific investments,  PMC will attempt to identify securities with
significant  potential  for  appreciation  relative to their  downside  exposure
and/or  which  have a timely  record  and high  level of  interest  or  dividend
payments.   In  making  these   determinations,   PMC  will  take  into  account
price-earnings  ratios,  cash flow,  the  relationship  of asset value to market
price of the securities,  interest or dividend payment history and other factors
which it may  determine  from time to time to be  relevant.  PMC will attempt to
allocate the Fund's portfolio investments across regional economies and property
types.
    

Risk Factors Associated with the Real Estate Industry

   Although  the Fund does not invest  directly in real  estate,  it does invest
primarily in Real Estate Equity  Securities and does concentrate its investments
in the real estate industry,  and,  therefore,  an investment in the Fund may be
subject to certain risks associated with the direct ownership of real estate and
with the real estate  industry in general.  These risks  include,  among others:
possible  declines  in the value of real  estate;  risks  related to general and
local economic  conditions;  possible lack of  availability  of mortgage  funds;
overbuilding;  extended  vacancies  of  properties;  increases  in  competition,
property taxes and operating  expenses;  changes in zoning laws; costs resulting
from the clean-up of, and liability to third parties for damages resulting from,
environmental problems;  casualty or condemnation losses; uninsured damages from
floods, earthquakes or other natural disasters; limitations on and variations in
rents; and changes in interest rates.

                                      -5-
<PAGE>

   In addition,  if the Fund has rental income or income from the disposition of
real property acquired as a result of a default on securities the Fund owns, the
receipt of such income may adversely affect its ability to retain its tax status
as a  regulated  investment  company.  See  "Tax  Status"  in the  Statement  of
Additional  Information.  Investments  by the Fund in  securities  of  companies
providing  mortgage  servicing  will be  subject  to the risks  associated  with
refinancings and their impact on servicing rights.

Real Estate Investment Trusts and Associated Risk Factors

   The Fund may invest without  limitation in shares of REITs.  REITs are pooled
investment  vehicles which invest  primarily in income  producing real estate or
real estate related loans or interests. REITs are generally classified as equity
REITs,  mortgage  REITs or a combination  of equity and mortgage  REITs.  Equity
REITs invest the majority of their assets  directly in real  property and derive
income  primarily  from the  collection of rents.  Equity REITs can also realize
capital gains by selling  properties  that have  appreciated in value.  Mortgage
REITs invest the majority of their  assets in real estate  mortgages  and derive
income from the collection of interest payments.  Like investment companies such
as the Fund, REITs are not taxed on income distributed to shareholders  provided
they comply with several  requirements of the Internal  Revenue Code of 1986, as
amended (the "Code").  The Fund will indirectly bear its proportionate  share of
any expenses  paid by REITs in which it invests in addition to the expenses paid
by the Fund.

   Investing in REITs  involves  certain unique risks in addition to those risks
associated with investing in the real estate  industry in general.  Equity REITs
may be affected by changes in the value of the underlying  property owned by the
REITs,  while  mortgage  REITs may be  affected  by the  quality  of any  credit
extended.  REITs are dependent upon management skills, are not diversified,  and
are subject to the risks of financing projects.  REITs are subject to heavy cash
flow dependency, default by borrowers,  self-liquidation,  and the possibilities
of failing to qualify for the exemption  from tax for  distributed  income under
the Code and failing to maintain their  exemptions  from the Investment  Company
Act of 1940, as amended (the "1940 Act").  REITs whose underlying assets include
long-term  health care  properties,  such as nursing,  retirement  and  assisted
living homes, may be impacted by federal regulations  concerning the health care
industry.

   REITs  (especially  mortgage  REITs) are also subject to interest rate risks.
When  interest  rates  decline,  the value of a REIT's  investment in fixed rate
obligations can be expected to rise.  Conversely,  when interest rates rise, the
value of a REIT's  investment  in fixed  rate  obligations  can be  expected  to
decline.  In contrast,  as interest rates on adjustable  rate mortgage loans are
reset periodically,  yields on a REIT's investments in such loans will gradually
align themselves to reflect changes in market interest rates,  causing the value
of such investments to fluctuate less  dramatically in response to interest rate
fluctuations than would investments in fixed rate obligations.

   Investing in REITs involves risks similar to those  associated with investing
in small capitalization  companies.  REITs may have limited financial resources,
may trade  less  frequently  and in a limited  volume and may be subject to more
abrupt or erratic price movements than larger company securities.  Historically,
small  capitalization  stocks,  such as REITs,  have been more volatile in price
than the larger capitalization stocks included in the Standard & Poor's Index of
500 Common Stocks.

Other Eligible Investments

   The Fund may invest up to 25% of its total  assets in any of the  investments
described in this section.

   
   Debt  Securities  of  Real  Estate  Industry  Companies  and  Mortgage-Backed
Securities.  The Fund may invest in debt securities (including  convertible debt
securities)  of real estate  industry  companies.  PMC intends to invest no more
than 5% of the  Fund's  net  assets  in debt  securities  rated,  at the time of
investment,  below Baa by Moody's Investors Service,  Inc. ("Moody's") or BBB by
Standard & Poor's Ratings Group ("Standard & Poor's") or, if unrated,  judged by
PMC to be of at least comparable quality. Securities rated Baa by Moody's or BBB
by  Standard & Poor's and  securities  of  comparable  quality,  referred  to as
"medium grade"  obligations,  have speculative  characteristics,  and changes in
economic  conditions  and other  factors  are more  likely  to lead to  weakened
capacity  to pay  principal  and  interest  than is the  case for  higher  rated
investment grade securities.  In the event a debt security purchased by the Fund
is subsequently  down graded below  investment  grade, PMC will consider whether
    

                                      -6-
<PAGE>

the Fund should  continue to hold the security.  See the Statement of Additional
Information for a description of the corporate debt ratings  assigned by Moody's
and Standard & Poor's and the risks associated with lower-rated debt securities.

   
   The Fund may also invest in securities that directly or indirectly  represent
participations  in, or are  collateralized  by and payable from,  mortgage loans
secured  by  real   property   ("Mortgage-Backed   Securities").   Investing  in
Mortgage-Backed  Securities  involves  certain unique risks in addition to those
associated  with investing in the real estate  industry in general.  These risks
include the failure of a counter-party to meet its commitments, adverse interest
rate changes and the effects of prepayments on mortgage cash flows. See Appendix
A for a more complete  description  of the  characteristics  of  Mortgage-Backed
Securities and associated risks.
    

   Short-Term  Investments.  The  Fund  may  invest  in  short-term  investments
consisting  of:  corporate  commercial  paper  and other  short-term  commercial
obligations,  in each case rated or issued by companies with similar  securities
outstanding that are rated Prime-1, Aa or better by Moody's or A-1, AA or better
by Standard & Poor's;  obligations  (including  certificates  of  deposit,  time
deposits,  demand  deposits and bankers'  acceptances)  of banks with securities
outstanding  that are rated  Prime-1,  Aa or better by  Moody's,  or A-1,  AA or
better by  Standard  & Poor's;  obligations  issued  or  guaranteed  by the U.S.
Government or its agencies or  instrumentalities  with remaining  maturities not
exceeding 18 months; and repurchase agreements.

Foreign Investments

   The Fund may invest up to 5% of its net assets in equity and debt  securities
of foreign  real  estate  companies.  See  "Foreign  Real Estate  Companies  and
Associated  Risks" in the Statement of Additional  Information for a description
of the risks associated with foreign investments.

Restricted and Illiquid Securities

   The Fund may  invest up to 5% of its net  assets in  securities  exempt  from
registration  and up to 15% of its  net  assets  in  illiquid  investments.  See
Appendix A for a description of the risks associated with these securities.

Non-Diversified Status

   The  Fund  is   "non-diversified"   for  purposes  of  the  1940  Act.  As  a
non-diversified  mutual  fund,  the  Fund  may  be  more  susceptible  to  risks
associated  with a single  economic,  political or regulatory  occurrence than a
diversified  fund might be.  Like most other  registered  investment  companies,
however,  the Fund intends to qualify as a "regulated  investment company" under
the  Code  and  therefore  will be  subject  to  diversification  limits,  which
generally require that, as of the close of each quarter of its taxable year, (i)
no more than 25% of its assets may be  invested  in the  securities  of a single
issuer (except for U.S.  Government  securities) and (ii) with respect to 50% of
its total  assets,  no more than 5% of its total  assets may be  invested in the
securities  of a single  issuer  (except  for  U.S.  Government  securities)  or
invested  in more  than 10% of the  outstanding  voting  securities  of a single
issuer.

Portfolio Turnover

   
   PMC  generally   avoids   market-timing   or   speculating  on  broad  market
fluctuations.   Therefore,   except  as  described   above,  the  Fund  will  be
substantially fully invested at all times.  Changes in the portfolio may be made
promptly when determined to be advisable by reason of developments  not foreseen
at the time of the initial investment decision, and usually without reference to
the length of time a security  has been held.  Accordingly,  portfolio  turnover
rates are not  considered  a  limiting  factor in the  execution  of  investment
decisions. See "Financial Highlights" for the Fund's actual turnover rates.
    

   The  Fund's  investment   objectives  and  certain  investment   restrictions
designated as  fundamental  in the Statement of  Additional  Information  may be
changed by the Board of Trustees only with shareholder approval.

IV.  MANAGEMENT OF THE FUND

   
   The Fund's Board of Trustees has overall  responsibility  for the  management
and supervision of the Fund. There are currently nine Trustees,  six of whom are
not "interested persons" of the Fund as defined in the 1940 Act. The Board meets
at  least  quarterly.  By  virtue  of  the  functions  performed  by  Pioneering
Management  Corporation  ("PMC") as  investment  adviser,  the Fund  requires no
employees  other  than  its  executive  officers,  all  of  whom  receive  their
compensation from PMC or other sources. The Statement of Additional  Information
contains the names and general  business  and  professional  background  of each
Trustee and executive officer of the Fund.

   The Fund is managed  under an  investment  advisory  contract  with PMC.  PMC
serves as  investment  adviser to the Fund and is  responsible  for the  overall
management of the Fund's business affairs,  subject only to the authority of the
Board of Trustees.  PMC is a wholly owned subsidiary of The Pioneer Group,  Inc.
("PGI"), a Delaware  corporation.  Pioneer Funds Distributor,  Inc. ("PFD"),  an
indirect wholly-owned  subsidiary of PGI, is the principal underwriter of shares
of the Fund. John F. Cogan,  Jr.,  Chairman and Chief  Executive  Officer of the
Fund,  Chairman  and a Director of PMC,  Chairman of PFD,  and  President  and a
Director of PGI, beneficially owned approximately 15% of the outstanding capital
stock of PGI as of the date of this Prospectus.

   Each  domestic  equity  portfolio  managed  by PMC,  including  the Fund,  is
overseen by the Domestic Equity Portfolio Management  Committee,  which consists
of PMC's most senior domestic equity  professionals  and a Portfolio  Management
Committee,  which consists of PMC's domestic  equity  portfolio  managers.  Both
committees are chaired by David D. Tripple, PMC's President and Chief Investment
Officer and Executive  Vice  President of each Pioneer  mutual fund.  Mr. Robert
Benson,  Senior Vice  President  of PMC,  has been  responsible  for  day-to-day
portfolio  decisions since the Fund's  inception.  Mr. Benson joined PMC in 1974
and is a Vice President of the Fund.
    

   The  executive  offices of PMC,  PGI and PFD are located at 60 State  Street,
Boston, Massachusetts 02109.

   
   Under  the terms of its  contract  with the Fund,  PMC  serves as the  Fund's
manager  and  investment  adviser  subject  to the  supervision  of  the  Fund's
Trustees.  PMC pays all the ordinary  operating  expenses,  including  executive
salaries  and the rental of office  space  relating to its services for the Fund
with the exception of the following  which are to be paid by the Fund: (a) taxes
and other governmental  charges, if any; (b) interest on borrowed money, if any;
(c) legal fees and expenses; (d) auditing fees; (e) insurance premiums; (f) dues
and fees  for  membership  in trade  associations;  (g)  fees  and  expenses  of
registering  and  maintaining  registrations  by the Fund of its shares with the
SEC, individual states,  territories and foreign  jurisdictions and of preparing
reports to government agencies; (h) fees and expenses of Trustees not affiliated
with or  interested  persons of PMC;  (i) fees and  expenses  of the  custodian,
dividend disbursing agent, transfer agent and registrar;  (j) issue and transfer
taxes chargeable to the Fund in connection with securities transactions to which
the Fund is a  party;  (k)  costs  of  reports  to  shareholders,  shareholders'
meetings  and  Trustees'  meetings;  (l) the cost of  certificates  representing
shares of the fund;  (m) fund  accounting,  pricing  and  appraisal  charges and
related  overhead;  and (n) distribution fees in accordance with Rule 12b-1. The
Fund also pays all  brokerage  commissions  and any  taxes or other  charges  in
connection  with  its  portfolio  transactions.  In  addition,  the  expense  of
organizing  the Fund and initially  registering  and qualifying its shares under
federal and state securities laws are being charged to the Fund's operations, as
an  expense,  over a period not to exceed 60 months  from the  Fund's  inception
date.
    

   Orders for the Fund's  portfolio  securities  transactions are placed by PMC,
which strives to obtain the best price and execution  for each  transaction.  In
circumstances  in which two or more  broker-dealers  are in a position  to offer
comparable  prices and  execution,  consideration  may be given to  whether  the
broker-dealer provides investment research or brokerage services or sells shares
of the Fund or other  Pioneer  mutual  funds.  See the  Statement of  Additional
Information for a further description of PMC's brokerage allocation practices.

   
   As  compensation  for its  management and  investment  advisory  services and
certain expenses which PMC incurs,  PMC is entitled to a management fee equal to
1.00% per annum of the Fund's  average  daily net  assets.  The fee is  normally
computed daily and paid monthly. The management fee, which is greater than those
paid by most  funds,  reflects  the added  complexity  and  additional  expenses
associated with analyzing real estate investments and related securities.
    

                                      -8-
<PAGE>

   
   During the fiscal periods ended June 30, 1994, December 31, 1994 and June 30,
1995,   the  Fund  incurred   expenses  of  $223,842,   $320,405  and  $335,514,
respectively,  including  management  fees paid or payable  to Pioneer  Winthrop
Advisors ("PWA") of $103,371, $141,284 and $130,341, respectively. PWA served as
the Fund's  investment  adviser from October 23, 1993 through July 17, 1995. PMC
has agreed  temporarily  to limit its  management  fee as  described in "Expense
Information."  During the fiscal periods ended June 30, 1994,  December 31, 1994
and June 30,  1995,  a similar  arrangement  by PWA  resulted in a reduction  of
expenses  for the Fund of $45,812,  $73,158  and  $107,417,  respectively.  This
agreement is voluntary  and  temporary  and may be revised or  terminated at any
time.
    


V. FUND SHARE ALTERNATIVES

   
   The Fund  continuously  offers three Classes of shares designated as Class A,
Class B and Class C shares, as described more fully in "How to Buy Fund Shares."
If you do not specify in your instructions to the Fund which Class of shares you
wish  to  purchase,   exchange  or  redeem,  the  Fund  will  assume  that  your
instructions apply to Class A shares.

   Class A Shares.  If you invest  less than $1  million in Class A shares,  you
will pay an initial  sales  charge.  Certain  purchases  may qualify for reduced
initial sales  charges.  If you invest $1 million or more in Class A shares,  no
sales charge will be imposed at the time of purchase,  however,  shares redeemed
within 12 months of  purchase  may be subject  to a  contingent  deferred  sales
charge ("CDSC").  Class A shares are subject to distribution and service fees at
a combined  annual  rate of up to 0.25% of the Fund's  average  daily net assets
attributable to Class A shares.

   Class B  Shares.  If you plan to invest up to  $250,000,  Class B shares  are
available to you.  Class B shares are sold without an initial sales charge,  but
are subject to a CDSC of up to 4% if redeemed  within six years.  Class B shares
are subject to distribution  and service fees at a combined annual rate of 1.00%
of the Fund's  average  daily net assets  attributable  to Class B shares.  Your
entire  investment  in Class B shares is available to work for you from the time
you make your investment, but the higher distribution fee paid by Class B shares
will cause your Class B shares (until conversion) to have a higher expense ratio
and to pay lower  dividends,  to the  extent  dividends  are paid,  than Class A
shares.  Class B shares will automatically  convert to Class A shares,  based on
relative net asset value, eight years after the initial purchase.

   Class C Shares.  Class C shares are sold without an initial sales charge, but
are  subject  to a 1% CDSC if they are  redeemed  within  the first  year  after
purchase.  Class C shares are  subject to  distribution  and  service  fees at a
combined  annual  rate of up to 1.00% of the  Fund's  average  daily net  assets
attributable  to Class C shares.  Your  entire  investment  in Class C shares is
available to work for you from the time you make your investment, but the higher
distribution fee paid by Class C shares will cause your Class C shares to have a
higher  expense ratio and to pay lower  dividends,  to the extent  dividends are
paid, than Class A shares. Class C shares have no conversion feature.

   Selecting  a Class of Shares.  The  decision  as to which  Class to  purchase
depends on the amount you invest, the intended length of the investment and your
personal  situation.  If you are making an investment that qualifies for reduced
sales charges,  you might  consider Class A shares.  If you prefer not to pay an
initial  sales charge on an  investment of $250,000 or less and you plan to hold
the investment for at least six years, you might consider Class B shares. If you
prefer not to pay an initial  sales charge and you plan to hold your  investment
for one to eight years, you may prefer Class C shares.

   Investment   dealers  or  their   representatives   may   receive   different
compensation  depending  on which  Class of  shares  they  sell.  Shares  may be
exchanged  only for shares of the same Class of another  Pioneer mutual fund and
shares  acquired  in the  exchange  will  continue  to be  subject  to any  CDSC
applicable to the shares of the Fund originally  purchased.  Shares sold outside
the U.S. to persons who are not U.S.  citizens may be subject to different sales
charges,  CDSCs and dealer  compensation  arrangements  in accordance with local
laws and business practices.

VI. SHARE PRICE

   
   Shares of the Fund are sold at the public  offering  price,  which is the net
asset value per share plus any applicable sales charge.  The net asset value per
share of each Class of the Fund shares is  determined  by dividing  the value of
its assets, less liabilities attributable to that Class, by the number of shares
of that Class  outstanding.  The net asset value is computed once daily, on each
day the New York Stock  Exchange  (the  "Exchange")  is open, as of the close of
regular trading on the Exchange.

   Securities  are valued at the last sale price on the  principal  exchange  or
market  where they are traded.  Securities  which have not traded on the date of
valuation or securities  for which sales prices are not  generally  reported are
valued at the mean between the current bid and asked prices.  Securities  quoted
in foreign  currencies are converted to U.S. dollars  utilizing foreign exchange
rates employed by the Fund's independent pricing services. Generally, trading in
foreign securities is substantially completed each day at various times prior to
the close of the Exchange.  The values of such  securities used in computing the
net asset value of the Fund's shares are  determined  as of such times.  Foreign
currency exchange rates are also generally  determined prior to the close of the
Exchange.  Occasionally,  events which affect the values of such  securities and
such exchange rates may occur between the times at which they are determined and
the close of the Exchange and will therefore not be reflected in the computation
of the Fund's net asset value. If events materially  affecting the value of such
securities  occur during such period,  then these securities are valued at their
fair value as determined  in good faith by the Trustees.  All assets of the Fund
for which there is no other  readily  available  valuation  method are valued at
their fair value as determined in good faith by the Trustees.


VII. HOW TO BUY FUND SHARES

   You may buy Fund  shares at the public  offering  price  from any  securities
broker-dealer having a sales agreement with PFD. If you do not have a securities
broker-dealer, please call 1-800-225-6292 for assistance.

  The minimum initial  investment is $1,000 for Class A, B and C shares,  except
as specified below.  The minimum initial  investment is $50 for Class A accounts
being established to utilize monthly bank drafts, government allotments, payroll
deduction  and  other  similar  automatic  investment  plans.  Separate  minimum
investment  requirements  apply to  retirement  plans and to telephone  and wire
orders  placed by  broker-dealers;  and no sales  charge or  minimum  investment
requirements   apply  to  the   reinvestment   of  dividends  or  capital  gains
distributions.  The minimum subsequent  investment is $50 for Class A shares and
$500 for Class B and C shares  except  that the  subsequent  minimum  investment
amount for Class B and C share  accounts may be as little as $50 if an automatic
investment plan (see "Automatic Investment Plans") is established.

   Telephone  Purchases.  Your account is  automatically  authorized to have the
telephone  purchase  privilege  unless you  indicated  otherwise on your Account
Application  or by writing  to  Pioneering  Services  Corporation  ("PSC").  The
telephone  purchase  option  may be used to  purchase  additional  shares for an
existing  fund  account;  it may not be used to establish a new account.  Proper
account  identification will be required for each telephone purchase.  A maximum
of $25,000 per account may be  purchased by  telephone  each day. The  telephone
purchase  privilege  is  available  to IRA  accounts but may not be available to
other types of retirement plan accounts. Call PSC for more information.

   You are strongly urged to consult with your financial representative prior to
requesting  a telephone  purchase.  To purchase  shares by  telephone,  you must
establish your bank account of record by completing the  appropriate  section of
your Account  Application or an Account  Options Form.  PSC will  electronically
debit  the  amount  of each  purchase  from  this  predesignated  bank  account.
Telephone  purchases may not be made for 30 days after the establishment of your
bank of record or any change to your bank information.

   Telephone purchases will be priced at the net asset value plus any applicable
sales charge next  determined  after PSC's  acceptance  of a telephone  purchase
instruction  and receipt of good funds  (usually  three days after the  purchase
    


                                      -10-

instruction).  You may always  elect to deliver  purchases  to PSC by mail.  See
"Telephone Transactions and Related Liabilities" for additional information.

Class A Shares

   You may buy Class A shares at the  public  offering  price,  that is, the net
asset value per share next computed  after receipt of a purchase  order,  plus a
sales charge as follows:
    

                                               Sales Charge as a % of
                                                      Dealer
                                          Net                        Allowance
                                        Offering      Amount         as a % of
       Amount of Purchase                Price       Invested          Price

$1 million or more                       -0-          -0-         See Below

   
No sales charge is payable at the time of purchase on  investments of $1 million
or more, or for investments by certain group plans ("Group Plans"), but for such
investments a contingent  deferred sales charge  ("CDSC") of 1.00% is imposed in
the event of a redemption  of Class A shares  within 12 months of purchase.  See
"Redemptions  and  Repurchases"  below.  PFD  may,  in  its  discretion,  pay  a
commission to broker-dealers who initiate and are responsible for such purchases
as follows: 1.00% on the first $1 million invested; 0.50% on the next $4 million
invested;  and 0.10% on the excess over $5 million  invested.  These commissions
shall not be payable if the purchaser is affiliated with the broker-dealer or if
the  purchase  represents  the  reinvestment  of a  redemption  made  during the
previous  12  calendar  months.  Broker-dealers  who  receive  a  commission  in
connection  with Class A share  purchases at net asset value by 401(a) or 401(k)
retirement  plans with 1,000 or more eligible  participants or with at least $10
million in plan assets will be required to return any commissions  paid or a pro
rata portion  thereof if the retirement plan redeems its shares within 12 months
of  purchase.  See also "How to Sell Fund  Shares."  In  connection  with  PGI's
acquisition of Mutual of Omaha Fund  Management  Company and contingent upon the
achievement  of certain sales  objectives,  PFD pays to Mutual of Omaha Investor
Services,  Inc. 50% of PFD's  retention of any sales  commission on sales of the
Fund's shares through such dealer.

   The schedule of sales  charges  above is  applicable  to purchases of Class A
shares  of the  Fund by (i) an  individual,  (ii) an  individual  and his or her
spouse and children  under the age of 21 and (iii) a trustee or other  fiduciary
of a trust estate or fiduciary  account or related trusts or accounts  including
pension,  profit-sharing  and other  employee  benefit  trusts  qualified  under
Section  401 or 408 of the  Internal  Revenue  Code of  1986,  as  amended  (the
"Code"),  although  more than one  beneficiary  is involved.  The sales  charges
applicable  to a  current  purchase  of Class A  shares  of the Fund by a person
listed above is  determined by adding the value of shares to be purchased to the
aggregate  value (at the then  current  offering  price) of shares of any of the
other Pioneer mutual funds previously purchased and then owned , provided PFD is
notified by such person or his or her broker-dealer each time a purchase is made
which would qualify. Pioneer mutual funds include all mutual funds for which PFD
serves as principal  underwriter.  See the "Letter of Intention"  section of the
Account Application.

   Qualifying for a Reduced Sales Charge. Class A shares of the Fund may be sold
at a reduced or eliminated  sales charge to certain group plans ("Group  Plans")
under which a sponsoring  organization makes  recommendations  to, permits group
solicitation of, or otherwise facilitates  purchases by, its employees,  members
or  participants.  Class A shares of the Fund may be sold at net asset value per
share  without a sales charge to  state-sponsored  Optional  Retirement  Program
participants  if (i) the employer has  authorized a limited number of investment
company  providers  for the  Program,  (ii) all  authorized  investment  company
providers offer their shares to Program  participants at net asset value,  (iii)
the employer has agreed in writing to actively promote the authorized investment
    


                                      -11-
<PAGE>

providers to Program  participants  and (iv) the Program provides for a matching
contribution  for  each  participant   contribution.   Information   about  such
arrangements is available from PFD.

   
   Class A shares  of the Fund may also be sold at net  asset  value  per  share
without a sales  charge to: (a) current or former  Trustees  and officers of the
Fund and partners  and  employees  of its legal  counsel;  (b) current or former
directors,   officers,   employees   or  sales   representatives   of  PGI,  its
subsidiaries;  (c) current or former  directors,  officers,  employees  or sales
representatives  of any  subadviser  or  predecessor  investment  adviser to any
investment  company  for which  PMC  serves as an  investment  adviser,  and the
subsidiaries  or  affiliates of such  persons;  (d) current or former  officers,
partners,  employees or registered  representatives of broker-dealers which have
entered into sales agreements with PFD; (e) members of the immediate families of
any of the persons above; (f) any trust, custodian,  pension,  profit-sharing or
other benefit plan of the foregoing  persons;  (g)  insurance  company  separate
accounts;  (h) certain  "wrap  accounts" for the benefit of clients of financial
planners adhering to standards  established by PFD; (i) other funds and accounts
for which PMC or any of its affiliates serves as investment  adviser or manager;
and (j) certain unit  investment  trusts.  Shares so purchased are purchased for
investment  purposes  and  may  not  be  resold  except  through  redemption  or
repurchase by or on behalf of the Fund.  The  availability  of this privilege is
conditioned on the receipt by PFD of written notification of eligibility.  Class
A shares of the Fund may also be sold at net asset value  without a sales charge
in  connection   with  certain   reorganization,   liquidation   or  acquisition
transactions involving other investment companies or personal holding companies.

   Reduced sales  charges for Class A shares are available  through an agreement
to purchase a specified quantity of Fund shares over a designated thirteen-month
period  by  completing  the  "Letter  of  Intention"   section  of  the  Account
Application.  Information about the "Letter of Intention"  procedure,  including
its terms, is contained on the back of the Account Application as well as in the
Statement  of   Additional   Information.   Investors   who  are  clients  of  a
broker-dealer  with a current  sales  agreement  with PFD may  purchase  Class A
shares of the Fund at net asset  value,  without a sales  charge,  to the extent
that the purchase price is paid out of proceeds from one or more  redemptions by
the investor of shares of certain other mutual funds. In order for a purchase to
qualify for this privilege, the investor must document to the broker-dealer that
the redemption  occurred  within 60 days  immediately  preceding the purchase of
Class A shares;  that the client paid a sales charge on the original purchase of
the shares  redeemed;  and that the mutual fund whose shares were  redeemed also
offers net asset value purchases to redeeming shareholders of any of the Pioneer
mutual funds. Further details may be obtained from PFD.

Class B Shares

   You may buy Class B shares at net asset value  without the  imposition  of an
initial  sales  charge;  however,  Class B shares  redeemed  within six years of
purchase  will be subject to a CDSC at the rates shown in the table  below.  The
charge will be assessed on the amount equal to the lesser of the current  market
value or the original  purchase cost of the shares being redeemed.  No CDSC will
be imposed on  increases  in account  value  above the initial  purchase  price,
including  shares  derived from the  reinvestment  of dividends or capital gains
distributions.

   The amount of the CDSC,  if any,  will vary  depending on the number of years
from the time of purchase  until the time of redemption  of Class B shares.  For
the purpose of  determining  the number of years from the time of any  purchase,
all payments during a quarter will be aggregated and deemed to have been made on
the first day of that quarter. In processing  redemptions of Class B shares, the
Fund will first  redeem  shares not  subject to any CDSC,  and then  shares held
longest  during  the  six-year  period.  As a  result,  you will pay the  lowest
possible CDSC.

   Proceeds  from  the  CDSC are paid to PFD and are used in whole or in part to
defray PFD's expenses related to providing  distribution-related services to the
Fund in  connection  with the sale of Class B shares,  including  the payment of
compensation to broker-dealers.

   
   Class B shares will  automatically  convert into Class A shares at the end of
the  calendar  quarter that is eight years after the  purchase  date,  except as
noted below.  Class B shares acquired by exchange from Class B shares of another
Pioneer  fund will  convert into Class A shares based on the date of the initial
purchase and the applicable CDSC.  Class B shares acquired through  reinvestment
of  distributions  will  convert  into  Class A shares  based on the date of the
initial purchase to which such shares relate.  For this purpose,  Class B shares
acquired through  reinvestment of distributions will be attributed to particular
purchases of Class B shares in accordance  with such  procedures as the Trustees
may  determine  from time to time.  The  conversion of Class B shares to Class A
shares is subject to the continuing  availability  of a ruling from the Internal
Revenue Service ("IRS") that such conversions will not constitute taxable events
for federal tax  purposes.  The  conversion  of Class B shares to Class A shares
will not occur if such ruling is not available  and,  therefore,  Class B shares
would  continue  to be  subject  to higher  expenses  than Class A shares for an
indeterminate period.

Class C Shares

   You may buy Class C shares at net asset value  without the  imposition  of an
initial  sales  charge;  however,  Class C shares  redeemed  within  one year of
purchase will be subject to a CDSC of 1.00%.  The charge will be assessed on the
amount equal to the lesser of the current market value or the original  purchase
cost of the shares  being  redeemed.  No CDSC will be imposed  on  increases  in
account value above the initial  purchase price,  including  shares derived from
the reinvestment of dividends or capital gains distributions.  Class C shares do
not convert to any other Class of Fund shares.

   For the purpose of determining the time of any purchase,  all payments during
a quarter  will be  aggregated  and deemed to have been made on the first day of
that quarter.  In processing  redemptions of Class C shares, the Fund will first
redeem  shares not subject to any CDSC,  and then  shares held for the  shortest
period of time during the one-year period. As a result,  you will pay the lowest
possible CDSC.

   Proceeds  from  the  CDSC are paid to PFD and are used in whole or in part to
defray PFD's expenses related to providing  distribution-related services to the
Fund in  connection  with the sale of Class C shares,  including  the payment of
compensation to broker-dealers.

Waiver or Reduction of Contingent  Deferred  Sales  Charge.  The CDSC on Class B
shares and on any Class A shares  subject to a CDSC may be waived or reduced for
non-retirement  accounts  if: (a) the  redemption  results from the death of all
registered owners of an account (in the case of UGMAs, UTMAs and trust accounts,
waiver applies upon the death of all beneficial owners) or a total and permanent
disability  (as  defined  in Section  72 of the Code) of all  registered  owners
occurring  after the purchase of the shares being redeemed or (b) the redemption
is made in  connection  with  limited  automatic  redemptions  as set  forth  in
"Systematic  Withdrawal  Plans"  (limited in any year to 10% of the value of the
account in the Fund at the time the withdrawal plan is established).

   The CDSC on Class B shares and on any Class A shares subject to a CDSC may be
waived or reduced for retirement  plan accounts if: (a) the  redemption  results
from the death or a total and permanent  disability (as defined in Section 72 of
the Code)  occurring  after the  purchase  of the  shares  being  redeemed  of a
shareowner or  participant  in an  employer-sponsored  retirement  plan; (b) the
distribution is to a participant in an Individual  Retirement  Account  ("IRA"),
403(b)  or   employer-sponsored   retirement  plan,  is  part  of  a  series  of
substantially equal payments made over the life expectancy of the participant or
the joint life  expectancy of the  participant  and his or her beneficiary or as
scheduled periodic payments to a participant  (limited in any year to 10% of the
value  of the  participant's  account  at the time the  distribution  amount  is
    


                                      -13-
<PAGE>

   
established; a required minimum distribution due to the participant's attainment
of age 70-1/2 may exceed the 10% limit only if the distribution  amount is based
on plan assets held by Pioneer); (c) the distribution is from a 401(a) or 401(k)
retirement  plan  and is a return  of  excess  employee  deferrals  or  employee
contributions  or a qualifying  hardship  distribution as defined by the Code or
results from a termination of employment  (limited with respect to a termination
to 10% per year of the value of the plan's assets in the Fund as of the later of
the prior December 31 or the date the account was established  unless the plan's
assets are being rolled over to or  reinvested  in the same class of shares of a
Pioneer mutual fund subject to the CDSC of the shares  originally held); (d) the
distribution is from an IRA, 403(b) or employer-sponsored retirement plan and is
to be  rolled  over to or  reinvested  in the same  class of shares in a Pioneer
mutual fund and which will be subject to the  applicable  CDSC upon  redemption;
(e) the  distribution  is in the form of a loan to a participant in a plan which
permits loans (each  repayment of the loan will constitute a new sale which will
be subject to the applicable CDSC upon  redemption);  or (f) the distribution is
from a  qualified  defined  contribution  plan and  represents  a  participant's
directed transfer (provided that this privilege has been pre-authorized  through
a prior agreement with PFD regarding participant directed transfers).

   The CDSC on Class C shares may be waived or reduced for either non-retirement
or retirement  plan accounts if: (a) the redemption  results from the death or a
total and permanent  disability (as defined in Section 72 of the Code) occurring
after the purchase of the shares being  redeemed of a shareowner or  participant
in an  employer-sponsored  retirement  plan.  The CDSC on Class C shares  may be
waived or reduced  for  retirement  plan  accounts if the  distribution  is to a
participant in an Individual  Retirement  Account ("IRA") or  employer-sponsored
retirement plan and is (a) part of a series of substantially equal payments made
over the life  expectancy of the participant or the joint life expectancy of the
participant and his or her  beneficiary;  (b) in the form of scheduled  periodic
payments to a  participant;  (c) a return of excess  employee  deferrals;  (d) a
qualifying hardship  distribution as defined by the Code; (e) from a termination
of employment; (f) the distribution is in the form of a loan to a participant in
a plan which permits loans; or (g) from a qualified  defined  contribution  plan
and represents a participant's  directed transfer  (provided that this privilege
has been pre-authorized through a prior agreement with PFD regarding participant
directed transfers).

   The CDSC on Class B and Class C shares and on any Class A shares subject to a
CDSC may be waived or  reduced  for either  non-retirement  or  retirement  plan
accounts if: (a) the  redemption is made by any state,  county,  or city, or any
instrumentality,  department,  authority, or agency thereof, which is prohibited
by applicable  laws from paying a CDSC in  connection  with the  acquisition  of
shares of any registered investment management company; or (b) the redemption is
made pursuant to the Fund's right to liquidate or involuntarily redeem shares in
a shareowner's account.

   Broker-Dealers.  An order for any Class of Fund shares received by PFD from a
broker-dealer prior to the close of regular trading on the Exchange is confirmed
at the price  appropriate  for that Class as  determined at the close of regular
trading on the Exchange on the day the order is received,  provided the order is
received prior to PFD's close of business (usually,  5:30 p.m. Eastern Time). It
is the  responsibility of broker-dealers to transmit orders so that they will be
received by PFD prior to its close of business.

   General.  The Fund reserves the right in its sole  discretion to withdraw all
or any part of the  offering  of shares  when,  in the  judgment  of the  Fund's
management,  such  withdrawal  is in the best  interest of the Fund. An order to
purchase shares is not binding on, and may be rejected by, PFD until it has been
confirmed in writing by PFD and payment has been received.


VIII. HOW TO SELL FUND SHARES

   You can arrange to sell  (redeem) Fund shares on any day the Exchange is open
by selling either some or all of your shares to the Fund.

   You may sell your shares either through your broker-dealer or directly to the
Fund. Please note the following:
    

                                      -14-
<PAGE>

   
o    If you are selling  shares from a  retirement  account,  you must make your
     request in writing  (except for  exchanges  to other  Pioneer  mutual funds
     which can be  requested by phone or in writing).  Call  1-800-622-0176  for
     more information.

o    If you are selling shares from a non-retirement account, you may use any of
     the methods described below.

   Your shares will be sold at the share price next calculated  after your order
is received and accepted less any applicable CDSC. Sale proceeds  generally will
be sent to you in cash, normally within seven days after your order is accepted.
The Fund  reserves  the right to  withhold  payment of the sale  proceeds  until
checks  received by the Fund in payment for the shares being sold have  cleared,
which may take up to 15 calendar days from the purchase date.

   In Writing. You may sell your shares by delivering a written request,  signed
by all registered owners, in good order to PSC, however,  you must use a written
request,  including  a  signature  guarantee,  to sell your shares if any of the
following situations applies:

o    you wish to sell over $50,000 worth of shares,
o    your account registration or address has changed within the last 30 days,
o    the check is not being  mailed to the address on your  account  (address of
     record),
o    the check is not being made out to the account owners, or
o    the sale proceeds are being  transferred  to a Pioneer  mutual fund account
     with a different registration.

   Your request  should  include your name,  the Fund's name,  your Fund account
number,  the Class of  shares to be  redeemed,  the  dollar  amount or number of
shares to be redeemed, and any other applicable requirements as described below.
Unless  instructed  otherwise,  PSC will  send the  proceeds  of the sale to the
address of record. Fiduciaries or corporations are required to submit additional
documents. For more information, contact PSC at 1-800-225-6292.

   Written  requests will not be processed until they are received in good order
and accepted by PSC.  Good order means that there are no  outstanding  claims or
requests to hold  redemptions on the account,  any  certificates are endorsed by
the record  owner(s)  exactly as the shares are registered and the  signature(s)
are guaranteed by eligible  guarantor.  You should be able to obtain a signature
guarantee from a bank, broker,  dealer,  credit union (if authorized under state
law),   securities   exchange  or   association,   clearing  agency  or  savings
association.  A notary public cannot  provide a signature  guarantee.  Signature
guarantees are not accepted by facsimile  ("fax").  For  additional  information
about the necessary  documentation for redemption by mail, please contact PSC at
1-800-225-6292.

   By Telephone or Fax.  Your account is  automatically  authorized  to have the
telephone  redemption  privilege unless you indicated  otherwise on your Account
Application or by writing to PSC. Proper account identification will be required
for each telephone redemption.  The telephone redemption option is not available
to  retirement  plan  accounts.  A maximum of $50,000 per account per day may be
redeemed by  telephone  or fax and the  proceeds  may be received by check or by
bank wire or electronic  funds transfer.  To receive the proceeds by check:  the
check must be made payable  exactly as the account is  registered  and the check

Related  Liabilities" below.  Telephone  redemptions will be priced as described
above.  You are  strongly  urged to consult with your  financial  representative
prior to requesting a telephone redemption.

   Selling Shares Through Your Broker-Dealer. The Fund has authorized PFD to act
as  its  agent  in  the   repurchase  of  shares  of  the  Fund  from  qualified
broker-dealers  and reserves the right to terminate  this procedure at any time.
Your broker-dealer must receive your request before the close of business on the
    


                                      -15-
<PAGE>

   
Exchange  and  transmit it to PFD before PFD's close of business to receive that
day's  redemption  price.  Your  broker-dealer  is responsible for providing all
necessary documentation to PFD and may charge you for its services.

Small  Accounts.  The minimum  account  value is $500. If you hold shares of the
Fund in an  account  with a net asset  value of less than the  minimum  required
amount due to redemptions  or exchanges,  the Fund may redeem the shares held in
this account at net asset value if you have not increased the net asset value of
the account to at least the minimum  required amount within six months of notice
by the Fund to you of the Fund's intention to redeem the shares.

   CDSC on Class A Shares. Purchases of Class A shares of $1,000,000 or more, or
by  participants  in a Group  Plan which  were not  subject to an initial  sales
charge,  may be subject to a CDSC upon  redemption.  A CDSC is payable to PFD on
these  investments in the event of a share redemption within 12 months following
the share  purchase,  at the rate of 1% of the lesser of the value of the shares
redeemed  (exclusive of reinvested  dividend and capital gain  distributions) or
the total cost of such shares.  Shares  subject to the CDSC which are  exchanged
into another  Pioneer  mutual fund will continue to be subject to the CDSC until
the  original  12-month  period  expires.  However,  no  CDSC  is  payable  upon
redemption  with  respect  to Class A  shares  purchased  by  401(a)  or  401(k)
retirement  plans with 1,000 or more eligible  participants or with at least $10
million in plan assets.

   General.  Redemptions may be suspended or payment postponed during any period
in which  any of the  following  conditions  exist:  the  Exchange  is closed or
trading on the Exchange is restricted;  an emergency exists as a result of which
disposal by the Fund of securities owned by it is not reasonably  practicable or
it is not reasonably  practicable for the Fund to fairly  determine the value of
the net assets of its portfolio; or the SEC, by order, so permits.

   Redemptions and repurchases are taxable transactions to shareholders. The net
asset value per share received upon redemption or repurchase may be more or less
than the cost of shares to an  investor,  depending  on the market  value of the
portfolio at the time of redemption or repurchase.

IX. HOW TO EXCHANGE FUND SHARES

   Written  Exchanges.  You may  exchange  your  shares  by  sending a letter of
instruction  to PSC. Your letter should  include your name, the name of the Fund
out of which you wish to exchange  and the name of the Pioneer  mutual fund into
which you wish to exchange, your fund account number(s),  the Class of shares to
be exchanged and the dollar amount or number of shares to be exchanged.  Written
exchange  requests must be signed by all record  owner(s)  exactly as the shares
are registered.

   Telephone  Exchanges.  Your account is  automatically  authorized to have the
telephone  exchange  privilege  unless you  indicated  otherwise on your Account
Application or by writing to PSC. Proper account identification will be required
for each telephone  exchange.  Telephone  exchanges may not exceed  $500,000 per
account per day. Each  voice-requested or FactFoneSM  telephone exchange request
will be  recorded.  You are  strongly  urged  to  consult  with  your  financial
representative  prior  to  requesting  a  telephone  exchange.   See  "Telephone
Transactions and Related Liabilities" below.

   Automatic Exchanges.  You may automatically  exchange shares from one Pioneer
account for shares of the same Class in another  Pioneer account on a monthly or
quarterly  basis.  The  accounts  must  have  identical  registrations  and  the
originating  account must have a minimum balance of $5,000. The exchange will be
effective  on the day of the month  designated  on your Account  Application  or
Account Options Form.

   General.  Exchanges must be at least $1,000. You may exchange your investment
from one Class of Fund shares at net asset value,  without a sales  charge,  for
shares of the same  Class of any other  Pioneer  mutual  fund.  Not all  Pioneer
mutual funds offer more than one Class of shares.  A new Pioneer  account opened
through an exchange must have a  registration  identical to that on the original
account.
    

                                      -16-
<PAGE>

   
   Any Class of shares which would normally be subject to a CDSC upon redemption
will not be  charged  the  applicable  CDSC at the time of an  exchange.  Shares
acquired  in an  exchange  will be subject to the CDSC of the shares  originally
held. For purposes of determining the amount of any applicable  CDSC, the length
of time you have owned  shares  acquired by exchange  will be measured  from the
date you acquired the original shares and will not be affected by any subsequent
exchange.

   Exchange  requests  received  by PSC before  4:00 p.m.  Eastern  Time will be
effective on that day if the requirements above have been met,  otherwise,  they
will be effective on the next  business  day.  PSC will process  exchanges  only
after receiving an exchange  request in good order.  There are currently no fees
or sales charges  imposed at the time of an exchange.  An exchange of shares may
be made only in states  where  legally  permitted.  For federal and  (generally)
state income tax purposes,  an exchange is considered to be a sale of the shares
of the Fund  exchanged and a purchase of shares in another  Pioneer mutual fund.
Therefore,  an  exchange  could  result  in a gain or loss on the  shares  sold,
depending  on the tax basis of these  shares and the timing of the  transaction,
and special tax rules may apply.

   You should consider the differences in objectives and policies of the Pioneer
mutual funds, as described in each fund's current prospectus,  before making any
exchange.  For the protection of the Fund's  performance and  shareholders,  the
Fund and PFD reserve the right to refuse any exchange  request or  restrict,  at
any time without  notice,  the number  and/or  frequency of exchanges to prevent
abuses of the exchange privilege. Such abuses may arise from frequent trading in
response  to  short-term  market  fluctuations,  a  pattern  of  trading  by  an
individual  or group that  appears to be an attempt to "time the market," or any
other exchange request which, in the view of management, will have a detrimental
effect  on the  Fund's  portfolio  management  strategy  or its  operations.  In
addition, the Fund and PFD reserve the right to charge a fee for exchanges or to
modify,  limit,  suspend or  discontinue  the exchange  privilege with notice to
shareholders as required by law.


X.  DISTRIBUTION PLANS

   The Fund has  adopted a Plan of  Distribution  for each Class of shares  (the
"Class A Plan,"  "Class B Plan,"  and  "Class C Plan") in  accordance  with Rule
12b-1 under the 1940 Act pursuant to which certain distribution fees are paid to
PFD.

   Pursuant  to the  Class A  Plan,  the  Fund  reimburses  PFD  for its  actual
expenditures to finance any activity primarily intended to result in the sale of
Class A shares or to provide services to holders of Class A shares, provided the
categories  of  expenses  for which  reimbursement  is made are  approved by the
Fund's  Board of  Trustees.  As of the  date of this  Prospectus,  the  Board of
Trustees has approved the following categories of expenses for Class A shares of
the Fund: (i) a service fee to be paid to qualified  broker-dealers in an amount
not to exceed  0.25% per annum of the Fund's  daily net assets  attributable  to
Class A shares; (ii) reimbursement to PFD for its expenditures for broker-dealer
commissions  and employee  compensation  on certain  sales of the Fund's Class A
shares with no initial  sales charge (See "How to Buy Fund  Shares");  and (iii)
reimbursement  to PFD for  expenses  incurred in  providing  services to Class A
shareholders  and supporting  broker-dealers  and other  organizations  (such as
banks and trust companies) in their efforts to provide such services.  Banks are
currently  prohibited  under  the  Glass-Steagall  Act  from  providing  certain
underwriting or distribution  services.  If a bank was prohibited from acting in
any  capacity or  providing  any of the  described  services,  management  would
consider what action, if any, would be appropriate.

   Expenditures  of the Fund  pursuant to the Class A Plan are accrued daily and
may not exceed  0.25% of the Fund's  average  daily net assets  attributable  to
Class A shares.  Distribution  expenses  of PFD are  expected  to  substantially
exceed the distribution  fees paid by the Fund in a given year. The Class A Plan
may not be amended to increase  materially the annual  percentage  limitation of
average net assets which may be spent for the services described therein without
approval of the shareholders of the Fund.

   Both  the  Class B Plan and the  Class C Plan  provide  that  the  Fund  will
compensate PFD by paying a  distribution  fee at the annual rate of 0.75% of the
Fund's average daily net assets  attributable to the applicable  Class of shares
and a service  fee at the annual rate of 0.25% of the Fund's  average  daily net
    


                                      -17-
<PAGE>

   
assets attributable to that Class of shares. The distribution fee is intended to
compensate  PFD for its Class B and Class C  distribution  services to the Fund.
The service fee is intended to be additional  compensation for personal services
and/or account  maintenance  services with respect to Class B or Class C shares.
PFD also receives the proceeds of any CDSC imposed on the  redemption of Class B
or Class C shares.
    

   Commissions of 4% of the amount invested in Class B shares, equal to 3.75% of
the amount  invested and a first year's service fee equal to 0.25% of the amount
invested,  are paid to broker-dealers  who have selling agreements with PFD. PFD
may advance to dealers  the first year  service fee at a rate up to 0.25% of the
purchase price of such shares and, as compensation therefore, PFD may retain the
service  fee paid by the Fund with  respect  to such  shares  for the first year
after  purchase.  Commencing in the 13th month following the purchase of Class B
shares, dealers will become eligible for additional annual service fees of up to
0.25% of the purchase price with respect to such shares.

   Commissions of up to 1% of the amount invested in Class C shares,  consisting
of 0.75% of the amount  invested and a first year's  service fee of 0.25% of the
amount invested,  are paid to  broker-dealers  who have selling  agreements with
PFD. PFD may advance to dealers the first year service fee at a rate up to 0.25%
of the purchase  price of such shares and, as  compensation  therefore,  PFD may
retain the  service  fee paid by the Fund with  respect  to such  shares for the
first year after  purchase.  Commencing in the 13th month following the purchase
of  Class  C  shares,   dealers  will  become  eligible  for  additional  annual
distribution fees and services fees of up to 0.75% and 0.25%,  respectively,  of
the purchase price with respect to such shares.

   Dealers may from time to time be required to meet  certain  criteria in order
to receive  service  fees.  PFD or its  affiliates  are  entitled  to retain all
service fees payable  under the Class B Plan or the Class C Plan for which there
is no dealer of record or for which qualification standards have not been met as
partial  consideration for personal services and/or account maintenance services
performed by PFD or its affiliates for shareowner accounts.

XI. DIVIDENDS, DISTRIBUTIONS AND TAXATION

   The Fund has elected to be treated, has qualified and intends to qualify each
year as a "regulated investment company" under Subchapter M of the Code, so that
it will not pay federal income taxes on income and capital gains  distributed to
shareholders at least annually.

   Under the Code, the Fund will be subject to a nondeductible 4% federal excise
tax on a portion of its  undistributed  income and capital  gains if it fails to
meet certain  distribution  requirements with respect to each calendar year. The
Fund intends to make  distributions  in a timely manner and accordingly does not
expect to be subject to the excise tax.

   The Fund's policy is to pay to  shareholders  dividends  from net  investment
income,  if any,  quarterly  during the  months of March,  June,  September  and
December and to make  distributions from net long-term capital gains, if any, in
December.  Distributions  from net short-term capital gains, if any, may be paid
with such dividends;  distributions from income and/or capital gains may also be
made at such times as may be  necessary to avoid  federal  income or excise tax.
Dividends from the Fund's net investment  income,  net short-term capital gains,
and certain  net foreign  exchange  gains are  taxable as ordinary  income,  and
dividends  from the Fund's net long-term  capital gains are taxable as long-term
capital gains.

   Unless   shareholders   specify   otherwise,   all   distributions   will  be
automatically  reinvested in additional full and fractional  shares of the Fund.
For federal  income tax purposes,  all dividends are taxable as described  above
whether a shareowner  takes them in cash or reinvests them in additional  shares
of  the  Fund.  Information  as to the  federal  tax  status  of  dividends  and
distributions  will  be  provided  annually.  For  further  information  on  the
distribution options available to shareholders,  see "Distribution  Options" and
"Directed Dividends" below.

   Distributions  by the Fund of the  dividend  income  it  receives  from  U.S.
domestic corporations,  if any, may qualify for the corporate dividends-received
deduction  for  corporate   shareholders,   subject  to  minimum  holding-period
requirements and debt-financing restrictions under the Code.


                                      -18-
<PAGE>

   
   Dividends and other distributions and the proceeds of redemptions,  exchanges
or repurchases of Fund shares paid to individuals  and other  non-exempt  payees
will be subject to a 31% backup withholding of federal income tax if the Fund is
not provided with the shareowner's  correct taxpayer  identification  number and
certification  that the number is correct and the  shareowner  is not subject to
backup  withholding or if the Fund receives notice from the IRS or a broker that
such withholding applies. Please refer to the Account Application for additional
information.

   The description  above relates only to U.S.  federal income tax  consequences
for shareholders who are U.S. persons,  i.e., U.S. citizens or residents or U.S.
corporations,  partnerships,  trusts  or  estates  and who are  subject  to U.S.
federal  income tax.  Non-U.S.  shareholders  and  tax-exempt  shareholders  are
subject to different tax treatment  that is not  described  above.  Shareholders
should  consult  their  own  tax  advisers  regarding  state,  local  and  other
applicable tax laws.
    

XII.  SHAREHOLDER SERVICES

   PSC is the  shareholder  services and transfer  agent for shares of the Fund.
PSC, a  Massachusetts  corporation,  is a wholly owned  subsidiary of PGI. PSC's
offices  are  located  at 60 State  Street,  Boston,  Massachusetts  02109,  and
inquiries to PSC should be mailed to Pioneering Services  Corporation,  P.O. Box
9014,  Boston,  Massachusetts  02205-9014.  Brown  Brothers  Harriman & Co. (the
"Custodian")  serves as the  custodian of the Fund's  portfolio  securities  and
other assets.  The principal business address of the Mutual Fund Division of the
Custodian is 40 Water Street, Boston, Massachusetts 02109.

Account and Confirmation Statements

   PSC maintains an account for each  shareholder  and all  transactions  of the
shareholder are recorded in this account.  Confirmation  statements  showing the
details  of  transactions  are  sent  to  shareholders  quarterly  for  dividend
reinvestment and  Investomatic  transactions and more frequently for other types
of transactions.  The Pioneer Combined Account Statement,  mailed quarterly,  is
available to all shareholders who have more than one Pioneer account.

   Shareholders whose shares are held in the name of an investment broker-dealer
or other party will not normally  have an account with the Fund and might not be
able to  utilize  some of the  services  available  to  shareholders  of record.
Examples of services that might not be available are investment or redemption of
shares by mail or  telephone,  automatic  reinvestment  of dividends and capital
gains distributions, systematic withdrawal plan, Letters of Intention, Rights of
Accumulation, telephone exchanges and redemptions, and newsletters.

Additional Investments

   
   You may add to your  account by sending a check  (minimum  of $50 for Class A
shares  and $500 for Class B and C shares) to PSC  (account  number and Class of
shares  should be  clearly  indicated).  The bottom  portion  of a  confirmation
statement may be used as a remittance slip to make additional investments.

   Additions to your account, whether by check or through a Pioneer Investomatic
Plan, are invested in full and  fractional  shares of the Fund at the applicable
offering price in effect as of the close of the Exchange on the day of receipt.

Automatic Investment Plans

   You may arrange  for regular  automatic  investments  of $50 or more  through
government/military   allotments,   payroll   deduction  or  through  a  Pioneer
Investomatic Plan. A Pioneer Investomatic Plan provides for monthly or quarterly
investments by means of a preauthorized electronic funds transfer or draft drawn
on a checking account.  Pioneer Investomatic Plan investments are voluntary, and
you may  discontinue  the Plan without  penalty upon 30 days' written  notice to
PSC.  PSC  acts  as  agent  for the  purchasers,  the  broker-dealer  and PFD in
maintaining Pioneer Investomatic Plans.

Financial Reports and Tax Information

   
   As a shareowner, you will receive financial reports at least semiannually. In
January of each year the Fund will mail to you information  about the tax status
of dividends and distributions.
    

Distribution Options

   Dividends and capital gains  distributions,  if any,  will  automatically  be
invested in additional shares of the Fund, at the applicable net asset value per
share, unless you indicate another option on the Account Application.

   Two other  options  available  are (a)  dividends  in cash and capital  gains
distributions in additional  shares;  and (b) all dividends and distributions in
cash. These two options are not available,  however,  for retirement plans or an
account  with a net asset value of less than $500.  Changes in the  distribution
option may be made by written request to PSC.

Directed Dividends

   
   You may elect (in writing) to have the dividends  paid by one Pioneer  mutual
fund account  invested in a second Pioneer mutual fund. The value of this second
account must be at least $1,000 ($500 for Pioneer Fund or Pioneer II).  Invested
dividends  may be in any amount.  There are no fees or charges for this service.
Retirement  plan  shareholders  may  only  direct  dividends  to  accounts  with
identical  registrations;  e.g.,  PGI IRA Cust for John  Smith  may only go into
another account registered PGI IRA Cust for John Smith.
    

Direct Deposit

   If you have elected to take distributions, whether dividends or dividends and
capital gains, in cash, or have  established a Systematic  Withdrawal  Plan, you
may choose to have those cash  payments  deposited  directly  into your savings,
checking,  or NOW bank account. You may establish this service by completing the
appropriate section on the Account Application when opening a new account or the
Account Options Form for an existing account.

Voluntary Tax Withholding

   You may request (in  writing)  that PSC  withhold  28% of the  dividends  and
capital gain  distributions  paid from an account (before any  reinvestment) and
forward the amount withheld to the Internal  Revenue Service as a credit against
federal income taxes.  This option is not available for retirement plan accounts
or for accounts subject to backup withholding.

Telephone Transactions and Related Liabilities

   
   Your  account  is  automatically  authorized  to have  telephone  transaction
privileges  unless you  indicated  otherwise on your Account  Application  or by
writing to PSC. You may purchase, sell or exchange your Fund shares by telephone
by calling 1-800- 225-6292  between the hours of 8:00 a.m. and 9:00 p.m. Eastern
Time on weekdays.  Computer-assisted  transactions are available to shareholders
who have  pre-recorded  certain  bank  information  (see  "FactFoneSM")  You are
strongly urged to consult with your financial representative prior to requesting
any telephone transaction. See "Share Price" for more information.

   To  confirm  that each  transaction  instruction  received  by  telephone  is
genuine, the Fund will record each telephone transaction,  require the caller to
provide the personal  identification number ("PIN") for the account and send you
a written confirmation of each telephone  transaction.  Different procedures may
apply to accounts that are  registered to non-U.S.  citizens or that are held in
the name of an  institution  or in the name of an  investment  broker-dealer  or
other third-party.  If reasonable procedures, such as those described above, are
not  followed,  the Fund may be  liable  for any  loss  due to  unauthorized  or
fraudulent instructions. In all other cases, neither the Fund, PSC nor PFD will
    


                                      -20-
<PAGE>

be  responsible  for the  authenticity  of  instructions  received by telephone,
therefore,  you bear the risk of loss for  unauthorized or fraudulent  telephone
transactions. The Fund may implement other procedures from time to time.

   During  times of  economic  turmoil  or market  volatility  or as a result of
severe weather or a natural disaster, it may be difficult to contact the Fund by
telephone to institute a redemption or exchange. You should communicate with the
Fund in writing if you are unable to reach the Fund by telephone.
   
FactFoneSM

   FactFoneSM is an automated inquiry and telephone transaction system available
to Pioneer  shareholders  by dialing  1-800-225-4321.  FactFoneSM  allows you to
obtain  current  information  on your Pioneer  accounts and to inquire about the
prices and yields of all publicly  available  Pioneer mutual funds. In addition,
you may use FactFoneSM to make computer-assisted telephone purchases,  exchanges
and  redemptions  from your  Pioneer  accounts if you have  activated  your PIN.
Telephone  purchases and redemptions require the establishment of a bank account
of record. You are strongly urged to consult with your financial  representative
prior to requesting any telephone  transaction.  Shareholders whose accounts are
registered in the name of a  broker-dealer  or other third party may not be able
to use FactFoneSM.  See "How to Buy Fund Shares," "How to Exchange Fund Shares,"
"How to Sell Fund Shares" and "Telephone  Transactions and Related Liabilities."
Call PSC for assistance.

Retirement Plans

   Please contact the Retirement Plans Department of PSC at  1-800-622-0176  for
information  relating to  retirement  plans for  business,  Simplified  Employee
Pension Plans,  Individual  Retirement  Accounts  (IRAs),  Section 401(k) salary
reduction  plans and Section  403(b)  retirement  plans for employees of certain
non-profit  organizations and public school systems,  all of which are available
in  conjunction   with   investments  in  the  Fund.  The  Account   Application
accompanying this Prospectus should not be used to establish such plans.
Separate applications are required.
    

Telecommunications Device for the Deaf (TDD)

   If you have a hearing disability and your own TDD keyboard equipment, you can
call our TDD number  toll-free at 1-800-  225-1997,  week days from 8:30 a.m. to
5:30 p.m. Eastern Time, to contact our telephone  representatives with questions
about your account.

Systematic Withdrawal Plans

   
   If your account has a total value of at least  $10,000,  you may  establish a
Systematic  Withdrawal  Plan  ("SWP")  providing  for fixed  payments at regular
intervals.  Withdrawals  from Class B share  accounts  are limited to 10% of the
value  of the  account  at the  time the plan is  implemented.  See  "Waiver  or
Reduction of Contingent  Deferred Sales Charge" for more  information.  Periodic
checks  of $50 or more will be sent to you,  or any  person  designated  by you,
monthly or quarterly,  and your periodic redemptions of shares may be taxable to
you.  Payments can be made either by check or by electronic  funds transfer to a
bank account  designated by you. If you direct that withdrawal checks be paid to
another  person after you have opened your account,  a signature  guarantee must
accompany your  instructions.  Purchases of Class A shares of the Fund at a time
when you have a SWP in effect may result in the  payment  of  unnecessary  sales
charges and may therefore be disadvantageous.
    

   You may obtain additional  information by calling PSC at 1-800-225-6292 or by
referring to the Statement of Additional Information.

   
Reinstatement Privilege (Class A Shares Only)

   If you  redeem  all or part  of your  Class A  shares  of the  Fund,  you may
reinvest all or part of the redemption  proceeds  without a sales  commission in
Class A shares of the Fund if you send a written request to PSC not more than 90
days  after  your  shares  were  redeemed.  Your  redemption  proceeds  will  be
reinvested at the next  determined  net asset value of the Class A shares of the
Fund  in  effect   immediately   after  receipt  of  the  written   request  for
reinstatement. You may realize a gain or loss for federal income tax purposes as
a result of the  redemption,  and special tax rules may apply if a  reinvestment
occurs.  You may also  reinvest in the Class A shares of certain  other  Pioneer
mutual funds; in this case you must meet the minimum investment  requirement for
each fund you enter.

   The 90-day  reinstatement  period may be extended by PFD for periods of up to
one year for  shareholders  living  in areas  that  have  experienced  a natural
disaster, such as a flood, hurricane, tornado, or earthquake.

   THE OPTIONS AND SERVICES  AVAILABLE TO  SHAREHOLDERS,  INCLUDING THE TERMS OF
THE  EXCHANGE  PRIVILEGE  AND THE  PIONEER  INVESTOMATIC  PLAN,  MAY BE REVISED,
SUSPENDED,  OR TERMINATED  AT ANY TIME BY PFD OR BY THE FUND.  YOU MAY ESTABLISH
THE SERVICES DESCRIBED IN THIS SECTION WHEN YOU OPEN YOUR ACCOUNT.  YOU MAY ALSO

XIII. THE FUND

   The Fund, a non-diversified  open-end management investment company (commonly
referred to as a mutual fund) was established as a Massachusetts  business trust
on July 1, 1993 and was  reorganized  as a Delaware  business trust on April 28,
1995 under an Agreement and  Declaration of Trust (the  "Declaration of Trust").
Prior to September 1, 1995,  the Fund was named  "Pioneer  Winthrop  Real Estate
Investment  Fund."  The Fund has  authorized  an  unlimited  number of shares of
beneficial  interest.  As an open-end investment company,  the Fund continuously
offers  its shares to the public and under  normal  conditions  must  redeem its
shares upon the demand of any shareowner at the then current net asset value per
share.  See "How to Sell Fund  Shares." The Fund is not  required,  and does not
intend,  to hold annual  shareowner  meetings  although  special meetings may be
called for the purpose of electing or removing  Trustees,  changing  fundamental
investment restrictions or approving a management contract.

   The Fund reserves the right to create and issue additional  series of shares.
The  Trustees  have the  authority,  without  further  shareowner  approval,  to
classify and reclassify the shares of the Fund, or any additional  series of the
Fund, into one or more classes. As of the date of this Prospectus,  the Trustees
have  authorized  the issuance of three classes of shares,  designated  Class A,
Class B and Class C. The shares of each class  represent an interest in the same
portfolio of investments of the Fund.  Each class has equal rights as to voting,
redemption,  dividends and  liquidation,  except that each class bears different
distribution  and  transfer  agent  fees and may bear  other  expenses  properly
attributable to the particular class.  Class A, Class B and Class C shareholders
have exclusive voting rights with respect to the Rule 12b-1  distribution  plans
adopted  by holders  of those  shares in  connection  with the  distribution  of
shares.

   In addition to the requirements  under Delaware law, the Declaration of Trust
provides that a shareholder of the Fund may bring a derivative  action on behalf
of the Fund only if the following conditions are met: (a) shareholders  eligible
to bring such derivative  action under Delaware law who hold at least 10% of the
outstanding  shares of the Fund, or 10% of the outstanding  shares of the series
or class  to which  such  action  relates,  shall  join in the  request  for the
Trustees  to  commence  such  action;  and (b) the  Trustees  must be afforded a
reasonable  amount of time to consider such shareholder  request and investigate
the basis of such claim.  The  Trustees  shall be entitled to retain  counsel or
other  advisers in  considering  the merits of the request and shall  require an
undertaking  by the  shareholders  making such request to reimburse the Fund for
the expense of any such advisers in the event that the Trustees determine not to
bring such action.

   When issued and paid for in accordance  with the terms of the  Prospectus and
Statement  of  Additional  Information,  shares of the Fund are  fully-paid  and
non-assessable. Shares will remain on deposit with the Fund's transfer agent and
    

                                      -21-

certificates will not normally be issued.  The Fund reserves the right to charge
a fee for the issuance of certificates.

XIV. INVESTMENT RESULTS

   The  average  annual  total  return (for a  designated  period of time) on an
investment  in the Fund may be  included in  advertisements,  and  furnished  to
existing or prospective  shareholders.  The average annual total return for each
Class is  computed  in  accordance  with the  SEC's  standardized  formula.  The
calculation  for all  Classes  assumes the  reinvestment  of all  dividends  and
distributions  at net asset  value and does not reflect the impact of federal or
state income taxes. In addition,  for Class A shares the calculation assumes the
deduction of the maximum  sales charge of 5.75%;  for Class B and Class C shares
the  calculation  reflects the  deduction of any  applicable  CDSC.  The periods
illustrated  would  normally  include  one,  five and ten  years  (or  since the
commencement  of the  public  offering  of the  shares of a Class,  if  shorter)
through the most recent calendar quarter.

   One or more additional measures and assumptions, including but not limited to
historical   total  returns;   distribution   returns;   results  of  actual  or
hypothetical investments;  changes in dividends,  distributions or share values;
or any graphic  illustration of such data may also be used. These data may cover
any  period of the Fund's  existence  and may or may not  include  the impact of
sales charges, taxes or other factors.

   Other  investments  or savings  vehicles  and/or  unmanaged  market  indexes,
indicators of economic  activity or averages of mutual fund results may be cited
or compared  with the  investment  results of the Fund.  Rankings or listings by
magazines,  newspapers or independent  statistical or rating  services,  such as
Lipper  Analytical  Services,  Inc., may also be  referenced.  The Fund may also
include  securities  industry,  real estate industry or comparative  performance
information  in  advertising  or materials  marketing  the Fund's  shares.  Such
performance   information  may  include   rankings  or  listings  by  magazines,
newspapers,  or  independent  statistical  or ratings  services,  such as Lipper
Analytical Services, Inc. or Ibbotson Associates.

   The Fund's investment results will vary from time to time depending on market
conditions,  the composition of the Fund's  portfolio and operating  expenses of
the Fund.  All  quoted  investment  results  are  historical  and  should not be
considered  representative  of what an  investment  in the  Fund may earn in any
future period. For further information about the calculation methods and uses of
the Fund's investment results, see the Statement of Additional Information.

From  time  to  time,   the  Fund  may  include  in   advertisements   or  other
communications to existing or proposed  shareholders its respective  "yield" and
"effective  yield."  Whenever  yield  information  is  provided,  it  includes a
standardized  yield  calculation  computed by dividing the Fund's net investment
income per share for a Class of Fund shares  during a base period of 30 days, or
one month,  by the maximum  offering price per share for that Class of shares on
the  last  day of  such  base  period.  The  resulting  "30-day  yield"  is then
annualized as described  below.  The Fund's net investment  income per share for
each Class is determined by dividing the Fund's net  investment  income for that
Class  during  the base  period by the  average  number of shares of that  Class
entitled to receive  dividends during the base period.  The Class's 30-day yield
is then  "annualized"  by a  computation  that  assumes  that  the  Class's  net
investment  income is earned and reinvested  for a six-month  period at the same
rate as during the 30-day base period and that the  resulting  six-month  income
will be generated over an additional six months.

For more  information  about the calculation  methods used to compute the Fund's
investment results, see the Statement of Additional Information.

APPENDIX A: Certain Investment Practices

   This Appendix provides a brief description of certain securities in which the
Fund may  invest  and  certain  transactions  it may make.  For a more  complete
discussion  of  these  and  other  securities  and  practices,  see  "Investment
Objectives  and  Policies"  in this  Prospectus  and  "Investment  Policies  and
Restrictions" in the Statement of Additional Information.

Mortgage-Backed Securities and Associated Risks

   The Fund may invest up to 25% of its total  assets in  mortgage  pass-through
certificates and  multiple-class  pass-through  securities,  such as real estate
mortgage investment conduits ("REMIC") pass-through certificates, collateralized
mortgage obligations ("CMOs") and stripped mortgage-backed  securities ("SMBS"),
and other  types of  Mortgage-Backed  Securities  that may be  available  in the
future.

   Guaranteed  Mortgage  Pass-Through   Securities.   The  Fund  may  invest  in
guaranteed  mortgage  pass-through   securities  which  represent  participation
interests  in  pools  of  residential  mortgage  loans  and are  issued  by U.S.
Governmental or private lenders and guaranteed by the U.S.  Government or one of
its agencies or  instrumentalities,  including but not limited to the Government
National  Mortgage  Association  ("Ginnie Mae"), the Federal  National  Mortgage
Association  ("Fannie  Mae")  and the  Federal  Home Loan  Mortgage  Corporation
("Freddie  Mac").  Ginnie Mae  certificates are guaranteed by the full faith and
credit of the United  States  government  for timely  payment of  principal  and
interest on the  certificates.  Fannie Mae certificates are guaranteed by Fannie
Mae, a federally chartered and  privately-owned  corporation for full and timely
payment of principal and interest on the certificates.  Freddie Mac certificates
are guaranteed by Freddie Mac, a corporate  instrumentality of the United States
government,  for timely  payment of interest and the ultimate  collection of all
principal of the related mortgage loans.

   Multiple-Class    Pass-Through   Securities   and   Collateralized   Mortgage
Obligations.  The  Fund may  also  invest  in CMOs  and  REMIC  pass-through  or
participation  certificates,   which  may  be  issued  by,  among  others,  U.S.
Government agencies and  instrumentalities as well as private lenders.  CMOs and
REMIC  certificates  are issued in  multiple  classes and the  principal  of and
interest on the mortgage  assets may be allocated  among the several  classes of
CMOs or  REMIC  certificates  in  various  ways.  Each  class  of CMOs or  REMIC
certificates,  often  referred  to  as a  "tranche,"  is  issued  at a  specific
adjustable  or fixed  interest  rate and must be fully retired no later than its
final distribution date.  Generally,  interest is paid or accrues on all classes
of CMOs or REMIC certificates on a monthly basis.

   Typically,  CMOs are  collateralized by Ginnie Mae, Fannie Mae or Freddie Mac
certificates  but also may be  collateralized  by other mortgage  assets such as
whole loans or private mortgage pass-through securities. Debt service on CMOs is
provided  from  payments of principal  and interest on  collateral  of mortgaged
assets and any reinvestment income thereon.

   A REMIC is a CMO that qualifies for special tax treatment  under the Code and
invests in certain mortgages primarily secured by interests in real property and
other  permitted  investments.  Investors may purchase  "regular" and "residual"
interest  shares of beneficial  interest in REMIC trusts  although the Fund does
not intend to invest in residual interests.

   Risk Factors Associated with Mortgage-Backed  Securities. As discussed above,
investing  in  Mortgage-Backed  Securities  involves  certain  unique  risks  in
addition to those risks associated with investing in the real estate industry in
general.  These  risks  include  the  failure  of a  counter-party  to meet  its
commitments,  adverse  interest rate changes and the effects of  prepayments  on
mortgage cash flows.  The Fund will not invest in the lowest tranche of CMOs and
REMIC certificates.  When interest rates decline,  the value of an investment in
fixed rate obligations can be expected to rise. Conversely,  when interest rates
rise,  the value of an investment in fixed rate  obligations  can be expected to
decline.  In contrast,  as interest rates on adjustable  rate mortgage loans are
reset  periodically,  yields on investments  in such loans will gradually  align
themselves to reflect  changes in market  interest  rates,  causing the value of
such  investments  to fluctuate less  dramatically  in response to interest rate
fluctuations than would investments in fixed rate obligations.

                                      -23-
<PAGE>

   Further,  the yield  characteristics of Mortgage-Backed  Securities,  such as
those in which the Fund may  invest,  differ  from  those of  traditional  fixed
income  securities.  The  major  differences  typically  include  more  frequent
interest and principal payments (usually monthly), the adjustability of interest
rates,   and  the  possibility   that  prepayments  of  principal  may  be  made
substantially earlier than their final distribution dates.

   Prepayment  rates are  influenced by changes in current  interest rates and a
variety  of  economic,  geographic,  social  and  other  factors  and  cannot be
predicted with  certainty.  Both  adjustable  rate mortgage loans and fixed rate
mortgage  loans may be subject to a greater rate of principal  prepayments  in a
declining   interest  rate  environment  and  to  a  lesser  rate  of  principal
prepayments in an increasing  interest rate environment.  Under certain interest
rate and  prepayment  rate  scenarios,  the Fund may fail to  recoup  fully  its
investment in Mortgage-Backed  Securities notwithstanding any direct or indirect
governmental or agency guarantee.  When the Fund reinvests amounts  representing
payments and  unscheduled  prepayments  of  principal,  it may receive a rate of
interest  that is lower  than  the rate on  existing  adjustable  rate  mortgage
pass-through securities.  Thus, Mortgage-Backed  Securities, and adjustable rate
mortgage pass-through securities in particular, may be less effective than other
types of U.S. Government securities as a means of "locking in" interest rates.

Repurchase Agreements

   The Fund may enter into repurchase agreements,  generally not exceeding seven
days. In a repurchase  agreement,  an investor (e.g., the Fund) purchases a debt
security  from a  seller  which  undertakes  to  repurchase  the  security  at a
specified resale price on an agreed future date (ordinarily a week or less). The
resale price generally exceeds the purchase price by an amount which reflects an
agreed-upon  market  interest  rate  for the term of the  repurchase  agreement.
Repurchase agreements entered into by the Fund will be fully collateralized with
United States Treasury and/or U.S.  Government agency  obligations with a market
value of not less than 100% of the obligation,  valued daily. Collateral will be
held in a  segregated,  safekeeping  account for the benefit of the Fund. In the
event that a repurchase agreement is not fulfilled, the Fund could suffer a loss
to the extent that the value of the collateral  falls below the repurchase price
or if the Fund is prevented from realizing the value of the collateral by reason
of an order of a court with  jurisdiction  over an  insolvency  proceeding  with
respect to the other party to the repurchase agreement.

Restricted and Illiquid Securities

   
   The Fund may  invest up to 5% of its net  assets in  "restricted  securities"
(i.e.,  securities that would be required to be registered prior to distribution
to the public),  excluding restricted  securities eligible for resale to certain
institutional  investors  pursuant to Rule 144A of the Securities Act of 1933 or
foreign  securities  which  are  offered  or sold  outside  the  United  States;
provided,  however,  that no more  than  15% of the  Fund's  net  assets  may be
invested in restricted securities including securities eligible for resale under
Rule  144A.  In  addition,  the Fund may  invest up to 15% of its net  assets in
illiquid investments, which includes securities that are not readily marketable,
repurchase  agreements  maturing in more than seven days.  The Board of Trustees
may adopt  guidelines and delegate to PMC the daily function of determining  and
monitoring  the liquidity of restricted  securities.  The Board,  however,  will
retain   sufficient   oversight   and  be   ultimately   responsible   for   the
determinations.
    

   Since it is not  possible to predict with  assurance  exactly how this market
for  restricted  securities  sold and offered under Rule 144A will develop,  the
Board  will  carefully  monitor  the  Fund's  investments  in these  securities,
focusing on such important  factors,  among others, as valuation,  liquidity and
availability of information.  This investment  practice could have the effect of
increasing  the level of  illiquidity  in the Fund to the extent that  qualified
institutional  buyers  become  for  a  time  uninterested  in  purchasing  these
restricted securities.

Limitations  and Risks  Associated  with  Transactions  in Options  and  Futures
Contracts

   The Fund may employ certain active management techniques including options on
securities indices,  futures contracts and options on futures contacts.  Each of


                                      -24-
<PAGE>

   
these active  management  techniques  involves  transaction costs as well as (1)
liquidity  risk that  contractual  positions  cannot be easily closed out in the
event of market  changes  or  generally  in the  absence  of a liquid  secondary
market,  (2) correlation risk that changes in the value of hedging positions may
not match the  securities  market  fluctuations  intended to be hedged,  and (3)
market risk that an incorrect  prediction of securities  prices by PMC may cause
the Fund to perform less well than if such  positions had not been entered.  The
ability to terminate over-the-counter options is more limited than with exchange
traded  options and may involve  the risk that the  counter-party  to the option
will not fulfill its obligations.  The Fund will treat over-the-counter  options
(both  purchased  and  written) as illiquid  securities.  The use of options and
futures  contracts are highly  specialized  activities which involve  investment
techniques  and risks that are  different  from those  associated  with ordinary
portfolio  transactions.  The loss that may be  incurred by the Fund in entering
into futures  contracts and written  options  thereon is potentially  unlimited.
There is no limit on the percentage of the Fund's assets that may be invested in
futures  contracts and related options.  The Fund may not invest more than 5% of
its total assets in purchased options other than protective put options.
    

   The Fund's transactions in options,  futures contracts and options on futures
contracts may be limited by the requirements for  qualification of the Fund as a
regulated investment company for tax purposes. See "Tax Status" in the Statement
of Additional  Information.  Options on Securities Indices The Fund may purchase
put and call options on securities indices that are based on securities in which
it may  invest  in an  attempt  to  hedge  against  risks of  market-wide  price
fluctuations.

   The  Fund may  purchase  put  options  in an  attempt  to  hedge  against  an
anticipated  decline in securities  prices that might adversely affect the value
of the Fund's  portfolio  securities.  If the Fund  purchases  a put option on a
securities index, the amount of the payment it would receive upon exercising the
option would depend on the extent of any decline in the level of the  securities
index below the exercise price.  Such payments would tend to offset a decline in
the  value of the  Fund's  portfolio  securities.  However,  if the level of the
securities  index  increases and remains above the exercise  price while the put
option is  outstanding,  the Fund will not be able to  profitably  exercise  the
option and will lose the amount of the premium and any transaction  costs.  Such
loss may be partially offset by an increase in the value of the Fund's portfolio
securities.

   The Fund may  purchase  call options on  securities  indices in an attempt to
lock in a favorable price on securities that it intends to buy in the future. If
the Fund  purchases  a call  option on a  securities  index,  the  amount of the
payment it  receives  upon  exercising  the  option  depends on the extent of an
increase in the level of other securities indices above the exercise price. Such
payments  would in  effect  allow the Fund to  benefit  from  securities  market
appreciation  even though it may not have had  sufficient  cash to purchase  the
underlying  securities.  Such payments may also offset increases in the price of
securities  that the Fund intends to  purchase.  If,  however,  the level of the
securities  index  declines and remains below the exercise  price while the call
option  is  outstanding,  the  Fund  will  not be able to  exercise  the  option
profitably and will lose the amount of the premium and transaction  costs.  Such
loss may be  partially  offset by a reduction  in the price the Fund pays to buy
additional securities for its portfolio.

   The Fund may sell an option it has purchased or a similar option prior to the
expiration  of the  purchased  option in order to close out its  position  in an
option  which  it has  purchased.  The Fund may also  allow  options  to  expire
unexercised, which would result in the loss of the premium paid.

Futures Contracts and Options on Futures Contracts

   To hedge against changes in securities prices or interest rates, the Fund may
purchase and sell  various  kinds of futures  contracts,  and purchase and write
call and put options on any of such futures  contracts.  The Fund may also enter
into  closing  purchase  and  sale  transactions  with  respect  to any of  such
contracts and options.  The futures contracts may be based on various securities
and other financial instruments and indices. The Fund will engage in futures and
related options  transactions for bona fide hedging purposes as are permitted by
regulations of the Commodity Futures Trading Commission.

   The Fund may not purchase or sell non-hedging  futures  contracts or purchase
or sell  related  non-hedging  options,  except  for  closing  purchase  or sale
transactions.   These  transactions  involve  brokerage  costs,  require  margin
deposits  and,  in the case of  contracts  and  options  obligating  the Fund to


                                      -25-
<PAGE>

purchase  securities,  require  the  Fund to  segregate  assets  to  cover  such
contracts and options.  Perfect correlation between the Fund's futures positions
and  portfolio  positions  will be  difficult  to  achieve  because  no  futures
contracts based on corporate fixed-income securities are currently available.

1.       GENERAL FUND INFORMATION AND HISTORY

         Effective  September  1, 1995,  the Fund  changed its name from Pioneer
Winthrop Real Estate Investment Fund to Pioneer Real Estate Shares. On April 28,
1995,  the  Fund,  a  Delaware  business  trust,  acquired  all the  assets  and
liabilities of Pioneer  Winthrop Real Estate  Investment  Fund, a  Massachusetts
business  trust  (the  "Massachusetts  Trust"),  in  a  tax-free  reorganization
effected  for  the  sole  purpose  of  changing  the  Fund's   domicile  from  a
Massachusetts  business trust to a Delaware  business  trust. In connection with
the  reorganization,  the Fund adopted the  Massachusetts  Trust's  Registration
Statement on Form N-1A.

2.       INVESTMENT POLICIES AND RESTRICTIONS
    

         The Prospectus of the Fund,  identifies  the investment  objectives and
the principal  investment policies of the Fund. Other investment policies of the
Fund are set forth below.  Capitalized  terms not otherwise  defined herein have
the meaning given to them in the Prospectus.

Lower-Rated Debt Securities and Associated Risks

   
         As  described  in the  Prospectus,  the  Fund  may  make a  variety  of
investments,  including  corporate  debt  obligations  of real  estate  industry
companies  which may be  unrated  or rated in the lowest  rating  categories  by
Standard & Poor's  Ratings  Group  ("Standard & Poor's") or by Moody's  Investor
Services, Inc. ("Moody's") (i.e., ratings of BB or lower by Standard & Poor's or
Ba or lower by Moody's).  Bonds rated BB or Ba or below (or  comparable  unrated
securities)  are  commonly  referred  to as  "junk  bonds"  and  are  considered
speculative and may be questionable  as to principal and interest  payments.  In
some  cases,  such  bonds may be highly  speculative,  have poor  prospects  for
reaching investment standing and be in default. As a result,  investment in such
bonds  will  entail  greater   speculative  risks  than  those  associated  with
investment  in  investment-grade  bonds  (i.e.,  bonds  rated  BBB or  better by
Standard  & Poor's  or Baa or  better  by  Moody's).  The Fund  will  limit  its
investment in non-investment  grade corporate debt  obligations,  and comparable
unrated debt obligations,  to less than 5% of its net assets. See Appendix A for
a description of the ratings issued by investment rating services.
    

         The amount of junk bond  securities  outstanding  has  proliferated  in
conjunction  with the increase in merger and  acquisition  and leveraged  buyout
activity.  An  economic  downturn  could  severely  affect the ability of highly
leveraged   issuers  to  service  their  debt  obligations  or  to  repay  their
obligations upon maturity.  Factors having an adverse impact on the market value
of lower rated  securities  will have an adverse  effect on the Fund's net asset
value to the extent it invests in such  securities.  In  addition,  the Fund may
incur  additional  expenses to the extent it is required to seek recovery upon a
default in payment of principal or interest on its portfolio holdings.

         The secondary market for junk bond securities, which is concentrated in
relatively few market makers,  may not be as liquid as the secondary  market for
more highly rated  securities,  a factor which may have an adverse effect on the
Fund's  ability to dispose of a particular  security when  necessary to meet its
liquidity  needs.  Under adverse  market or economic  conditions,  the secondary


                                      B-2
<PAGE>

   
market for junk bond  securities  could  contract  further,  independent  of any
specific adverse changes in the condition of a particular  issuer.  As a result,
Pioneering Management  Corporation ("PMC"), the Fund's investment adviser, could
find it more  difficult  to sell  these  securities  or may be able to sell  the
securities  only at prices  lower than if such  securities  were widely  traded.
Prices realized upon the sale of such lower rated or unrated  securities,  under
these circumstances,  may be less than the prices used in calculating the Fund's
net asset value.
    

         Certain  proposed  and recently  enacted  federal  laws  including  the
required  divestiture by federally  insured savings and loan associates of their
investments  in junk bonds and  proposals  designed to limit the use, or tax and
other advantages,  of junk bond securities could adversely affect the Fund's net
asset value and investment practices. Such proposals could also adversely affect
the  secondary  market for junk bond  securities,  the  financial  condition  of
issuers of these  securities and the value of outstanding  junk bond securities.
The form of such proposed  legislation and the  probability of such  legislation
being passed are uncertain.

         Since  investors  generally  perceive  that  there  are  greater  risks
associated  with the medium to lower rated  securities  of the type in which the
Fund may invest,  the yields and prices of such securities may tend to fluctuate
more than those for higher rated  securities.  In the lower quality  segments of
the  fixed-income   securities  market,   changes  in  perceptions  of  issuers'
creditworthiness  tend to occur more frequently and in a more pronounced  manner
than do changes in higher quality segments of the fixed-income securities market
resulting in greater yield and price volatility.

         Another factor which causes  fluctuations in the prices of fixed-income
securities is the supply and demand for similarly rated securities. In addition,
the prices of fixed-income securities fluctuate in response to the general level
of interest rates. Fluctuations in the prices of portfolio securities subsequent
to their  acquisition  will not affect cash income from such securities but will
be reflected in the Fund's net asset value.

   
         Medium to lower rated and comparable  unrated  securities tend to offer
higher yields than higher rated securities with the same maturities  because the
historical  financial  condition of the issuers of such  securities may not have
been as strong as that of other issuers.  Since medium to lower rated securities
generally  involve  greater  risks of loss of income and  principal  than higher
rated  securities,  investors  should  consider  carefully  the  relative  risks
associated with investment in securities which carry medium to lower ratings and
in comparable unrated securities.  In addition to the risk of default, there are
the related  costs of recovery on defaulted  issues.  PMC will attempt to reduce
these risks through  diversification  of the Fund's portfolio and by analysis of
each issuer and its ability to make timely payments of income and principal,  as
well as broad economic trends in corporate developments.
    

Foreign Real Estate Companies and Associated Risks

         The Fund may invest up to 5% of its net assets in securities of foreign
real estate  companies.  Such  investments  involve  certain risks which are not
typically  associated  with  investing  in  securities  of domestic  real estate
companies. Foreign companies are not subject to uniform accounting, auditing and


                                      B-3
<PAGE>

   
financial  standards and  requirements  comparable to those applicable to United
States companies.  There may also be less government  supervision and regulation
of foreign securities exchanges, brokers and listed companies than exists in the
United States.  Interest and dividends paid by foreign issuers may be subject to
withholding  and other  foreign taxes which will decrease the net return on such
investments  as compared to interest and dividends  paid to the Fund by the U.S.
Government or by domestic companies.  In addition,  there may be the possibility
of  expropriation,   confiscatory  taxation,   political,   economic  or  social
instability,  or diplomatic  developments  which could affect assets of the Fund
invested in foreign securities.
    

         In  addition,  the value of foreign  securities  may also be  adversely
affected  by  fluctuations  in  the  relative  rates  of  exchange  between  the
currencies of different nations and exchange control  regulations.  There may be
less publicly available  information about foreign companies compared to reports
and ratings published about United States companies.  Foreign securities markets
have  substantially  less trading volume than domestic markets and securities of
some foreign  companies  are less liquid and more  volatile  than  securities of
comparable  United States  companies.  Transaction  costs on foreign  securities
exchanges are generally higher than in the U.S.

   
         The Fund's investments in securities  denominated in foreign currencies
are also subject to currency risk, as the U.S. dollar value of these  securities
may be favorably or unfavorably affected by changes in foreign currency exchange
rates and exchange control  regulations.  Currency  exchange rates may fluctuate
significantly  over short  periods of time  causing,  among other  factors,  the
Fund's  net  asset  value to  fluctuate  as well.  Currency  exchange  rates are
generally  determined by forces of supply and demand and the perceived  relative
merits of investments in various countries, but can be affected unpredictable by
intervention  from U.S.  and foreign  governments  or central  banks,  political
events and currency control measures. PMC will take these and other factors into
consideration in managing the Fund's investments.
    

Securities Index Options

         The Fund may purchase  call and put options on  securities  indices for
the purpose of hedging against the risk of unfavorable price movements adversely
affecting the value of the Fund's  securities or securities  the Fund intends to
buy. Securities index options will not be used for speculative purposes.

   
         Options on stock  indices are traded on national  securities  exchanges
and  over-the-counter,  both in the United  States and in foreign  countries.  A
securities  index fluctuates with changes in the market values of the securities
included in the index.  For  example,  some stock  index  options are based on a
broad market index such as the S&P 500 or the Value Line Composite Index.  Index
options may also be based on a narrower  market  index such as the S&P 100 or on
an industry or market segment such as the AMEX Oil and Gas Index or the Computer
and Business Equipment Index.
    

                                      B-4
<PAGE>

         The Fund may  purchase  put  options  in  order  to  hedge  against  an
anticipated  decline in securities  prices that might adversely affect the value
of the Fund's  portfolio  securities.  If the Fund  purchases  a put option on a
securities index, the amount of the payment it would receive upon exercising the
option would depend on the extent of any decline in the level of the  securities
index below the exercise price.  Such payments would tend to offset a decline in
the  value of the  Fund's  portfolio  securities.  However,  if the level of the
securities  index  increases and remains above the exercise  price while the put
option is  outstanding,  the Fund will not be able to  profitably  exercise  the
option and will lose the amount of the premium and any transaction  costs.  Such
loss may be partially offset by an increase in the value of the Fund's portfolio
securities.

         The Fund may purchase call options on securities  indices in an attempt
to lock in a favorable price on securities that it intends to buy in the future.
If the Fund  purchases a call option on a  securities  index,  the amount of the
payment it  receives  upon  exercising  the  option  depends on the extent of an
increase in the level of other securities indices above the exercise price. Such
payments  would in  effect  allow the Fund to  benefit  from  securities  market
appreciation  even though it may not have had  sufficient  cash to purchase  the
underlying  securities.  Such payments may also offset increases in the price of
securities  that the Fund intends to  purchase.  If,  however,  the level of the
securities  index  declines and remains below the exercise  price while the call
option  is  outstanding,  the  Fund  will  not be able to  exercise  the  option
profitably and will lose the amount of the premium and transaction  costs.  Such
loss may be  partially  offset by a reduction  in the price the Fund pays to buy
additional securities for its portfolio.

         The Fund may sell the securities index option it has purchased or write
a similar offsetting securities index option in order to close out a position in
a  securities   index  option  which  it  has  purchased.   These  closing  sale
transactions  enable the Fund to immediately realize gains or minimize losses on
its options  positions.  However,  there is no assurance that a liquid secondary
market on an options  exchange will exist for any particular  option,  or at any
particular  time,  and for some  options  no  secondary  market  may  exist.  In
addition,  securities  index  prices may be distorted  by  interruptions  in the
trading of securities of certain companies or of issuers in certain  industries,
or by  restrictions  that may be  imposed by an  exchange  on opening or closing
transactions,  or both,  which would disrupt  trading in options on such indices
and  preclude the Fund from  closing out its options  positions.  If the Fund is
unable to effect a closing sale  transaction with respect to options that it has
purchased, it would have to exercise the options in order to realize any profit.

         The hours of trading for  options  may not conform to the hours  during
which the  underlying  securities  are  traded.  To the extent  that the options
markets  close  before the markets for the  underlying  securities,  significant
price and rate movements can take place in the  underlying  markets that can not
be  reflected  in the  options  markets.  The  purchase  of  options is a highly
specialized  activity which involves  investment  techniques and risks different
from those associated with ordinary portfolio securities transactions.

                                      B-5
<PAGE>

         In addition to the risks of  imperfect  correlation  between the Fund's
portfolio and the index underlying the option,  the purchase of securities index
options  involves  the risk that the premium and  transaction  costs paid by the
Fund in  purchasing  an option  will be lost.  This  could  occur as a result of
unanticipated  movements in prices of the  securities  comprising the securities
index on which the option is based.

Futures Contracts and Options on Futures Contracts

         To hedge against  changes in securities  prices,  the Fund may purchase
and sell various kinds of futures contracts,  and purchase and write (sell) call
and put options on any of such futures  contracts.  The Fund may also enter into
closing purchase and sale transactions with respect to any of such contracts and
options.  The futures contracts may be based on various securities (such as U.S.
Government  securities),  securities indices and other financial instruments and
indices.  The Fund will engage in futures and related options  transactions  for
bona fide hedging and,  although the Fund has no current  intention of doing so,
for non-hedging  purposes as described below. All futures contracts entered into
by the Fund are traded on U.S.  exchanges  or boards of trade that are  licensed
and regulated by the Commodity  Futures  Trading  Commission  (the "CFTC") or on
foreign exchanges.

         Futures Contracts.  A futures contract may generally be described as an
agreement between two parties to buy and sell particular  financial  instruments
for an agreed  price  during a  designated  month (or to deliver  the final cash
settlement  price,  in the case of a contract  relating to an index or otherwise
not calling for physical delivery at the end of trading in the contract).

         When interest  rates are rising or securities  prices are falling,  the
Fund can  seek to  offset  a  decline  in the  value  of its  current  portfolio
securities  through  the sale of  futures  contracts.  When  interest  rates are
falling or  securities  prices are rising,  the Fund,  through  the  purchase of
futures contracts, can attempt to secure better rates or prices than might later
be available in the market when it effects anticipated purchases.

         Positions  taken  in the  futures  markets  are  not  normally  held to
maturity but are instead liquidated  through  offsetting  transactions which may
result  in a  profit  or a loss.  A  clearing  corporation  associated  with the
exchange on which futures on  securities  are traded  guarantees  that, if still
open, the sale or purchase will be performed on the settlement date.

   
         Hedging  Strategies.  Hedging,  by use of futures  contracts,  seeks to
establish  with  more  certainty  the  effective  price  and rate of  return  on
portfolio  securities and securities  that the Fund owns or proposes to acquire.
The Fund may,  for  example,  take a "short"  position in the futures  market by
selling  futures  contracts  in order to hedge  against an  anticipated  rise in
interest  rates that would  adversely  affect the value of the Fund's  portfolio
securities. Such futures contracts may include contracts for the future delivery
of securities  held by the Fund or securities  with  characteristics  similar to
those of the Fund's portfolio securities.  If, in the opinion of PMC, there is a
sufficient  degree of correlation  between price trends for the Fund's portfolio
securities  and  futures   contracts  based  on  other  financial   instruments,
securities  indices or other indices,  the Fund may also enter into such futures
contracts as part of its hedging  strategy.  Although  under some  circumstances


                                      B-6
<PAGE>

prices of securities  in the Fund's  portfolio may be more or less volatile than
prices of such  futures  contracts,  PMC will  attempt to estimate the extent of
this volatility  difference based on historical  patterns and compensate for any
such  differential  by having the Fund enter into a greater or lesser  number of
futures contracts or by attempting to achieve only a partial hedge against price
changes  affecting  the  Fund's  securities  portfolio.  When  hedging  of  this
character is successful,  any depreciation in the value of portfolio  securities
will be  substantially  offset  by  appreciation  in the  value  of the  futures
position. On the other hand, any unanticipated  appreciation in the value of the
Fund's portfolio  securities  would be substantially  offset by a decline in the
value of the futures position.
    

         On other  occasions,  the Fund may take a "long" position by purchasing
futures  contracts.  This would be done, for example,  when the Fund anticipates
the subsequent purchase of particular securities when it has the necessary cash,
but  expects  the  prices or  currency  exchange  rates  then  available  in the
applicable  market to be less  favorable than prices or rates that are currently
available.

         Options on Futures  Contracts.  The acquisition of put and call options
on futures contracts will give the Fund the right (but not the obligation) for a
specified  price to sell or to purchase,  respectively,  the underlying  futures
contract at any time during the option period.  As the purchaser of an option on
a futures  contract,  the Fund  obtains the  benefit of the futures  position if
prices move in a favorable direction but limits its risk of loss in the event of
an unfavorable price movement to the loss of the premium and transaction costs.

         The writing of a call option on a futures contract  generates a premium
which may  partially  offset a decline  in the value of the  Fund's  assets.  By
writing a call option, the Fund becomes obligated,  in exchange for the premium,
to sell a futures  contract,  which may have a value  higher  than the  exercise
price. Conversely, the writing of a put option on a futures contract generates a
premium which may partially  offset an increase in the price of securities  that
the Fund intends to purchase.  However, the Fund becomes obligated to purchase a
futures contract which may have a value lower than the exercise price. Thus, the
loss incurred by the Fund in writing options on futures is potentially unlimited
and may  exceed  the  amount  of the  premium  received.  The  Fund  will  incur
transaction costs in connection with the writing of options on futures.

         The holder or writer of an option on a futures  contract may  terminate
its position by selling or purchasing  an offsetting  option on the same series.
There is no guarantee that such closing transactions can be effected. The Fund's
ability to establish  and close out positions on such options will be subject to
the development and maintenance of a liquid market.

         Other  Considerations.  The Fund may  engage  in  futures  and  related
options  transactions  only for bona fide hedging and,  although the Fund has no
current intention of doing so, for non-hedging  purposes in accordance with CFTC
regulations  which permit principals of an investment  company  registered under
the  Investment  Company Act of 1940, as amended (the "1940 Act"),  to engage in
such transactions  without registering as commodity pool operators.  The Fund is
not permitted to engage in speculative futures trading.  The Fund will determine


                                      B-7
<PAGE>

that the price fluctuations in the futures contracts and options on futures used
for  hedging  purposes  are  substantially  related  to  price  fluctuations  in
securities held by the Fund or which it expects to purchase.  The Fund's futures
transactions  will be entered  into for  traditional  hedging  purposes -- i.e.,
futures  contracts  will be sold to  protect  against a decline  in the price of
securities that the Fund owns, or futures contracts will be purchased to protect
the Fund against an increase in the price of  securities it intends to purchase.
As evidence of this hedging intent,  the Fund expects that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of purchasing, equivalent amounts of related securities or assets in the
cash  market at the time when the  futures  or option  position  is closed  out.
However, in particular cases, when it is economically  advantageous for the Fund
to do so, a long  futures  position  may be  terminated  or an option may expire
without the corresponding purchase of securities or other assets.

         As an  alternative  to literal  compliance  with the bona fide  hedging
definition,  a CFTC  regulation  permits  the  Fund to elect  to  comply  with a
different test, under which the sum of the amounts of initial margin deposits on
the  Fund's  existing  non-hedging  futures  contracts  and  premiums  paid  for
non-hedging  options on futures  (net of the  amount the  positions  are "in the
money") would not exceed 5% of the market value of the Fund's total  assets.  As
noted  above,  the Fund has no current  intention of entering  into  non-hedging
futures  contracts and non-hedging  options on futures.  The Fund will engage in
transactions  in futures  contracts and related  options only to the extent such
transactions  are consistent with the  requirements of the Internal Revenue Code
of 1986,  as amended  (the  "Code"),  for  maintaining  its  qualification  as a
regulated investment company for federal income tax purposes.

         Transaction costs associated with futures contracts and related options
involve  brokerage costs,  require margin deposits and, in the case of contracts
and  options  obligating  the Fund to purchase  securities,  require the Fund to
segregate assets to cover such contracts and options.

         While  transactions  in futures  contracts  and  options on futures may
reduce certain risks, such  transactions  themselves entail certain other risks.
Thus, while the Fund may benefit from the use of futures and options on futures,
unanticipated  changes in interest  rates or  securities  prices may result in a
poorer  overall  performance  for the Fund than if it had not  entered  into any
futures  contracts  or  options  transactions.  In  the  event  of an  imperfect
correlation  between  a  futures  position  and a  portfolio  position  which is
intended to be  protected,  the desired  protection  may not be obtained and the
Fund may be exposed to risk of loss.  The only  futures  contracts  available to
hedge the Fund's  portfolio are various futures on U.S.  Government  securities,
futures on a municipal securities index and stock index futures.

Repurchase Agreements

         The Fund may enter into repurchase agreements with "primary dealers" in
U.S. Government  securities and member banks of the Federal Reserve System which
furnish  collateral  at least  equal in value or market  price to the  amount of
their repurchase obligation.  The Fund may also enter into repurchase agreements
involving certain foreign  government  securities.  The primary risk is that, if
the  seller  defaults,  the  Fund  might  suffer a loss to the  extent  that the


                                      B-8
<PAGE>

proceeds from the sale of the underlying securities and other collateral held by
the Fund in connection with the related  repurchase  agreement are less than the
agreed-upon  repurchase price.  Another risk is that, in the event of bankruptcy
of the seller,  the Fund could be delayed in or prohibited from disposing of the
underlying  securities and other  collateral held by the Fund in connection with
the related  repurchase  agreement  pending  court  proceedings.  In  evaluating
whether to enter a repurchase agreement, the Manager will carefully consider the
creditworthiness  of the seller pursuant to procedures  reviewed and approved by
the Trustees.

Investment Restrictions

         The Fund has adopted certain additional  investment  restrictions which
may not be changed without the affirmative  vote of the holders of a majority of
the Fund's outstanding voting securities. The Fund may not:

         (1) Issue senior securities, except as permitted by paragraphs (2), (6)
and (7) below.  For  purposes  of this  restriction,  the  issuance of shares of
beneficial  interest  in  multiple  classes or series,  the  purchase or sale of
options,   futures   contracts  and  options  on  futures   contracts,   forward
commitments,  forward  foreign  exchange  contracts,  repurchase  agreements and
reverse  repurchase  agreements  entered  into in  accordance  with  the  Fund's
investment  policy,  and the  pledge,  mortgage or  hypothecation  of the Fund's
assets  within the  meaning of  paragraph  (3) below are not deemed to be senior
securities.

         (2)  Borrow  money,  except  from  banks  as a  temporary  measure  for
extraordinary  emergency  purposes  and except  pursuant  to reverse  repurchase
agreements  and then only in amounts  not to exceed 33 1/3% of the Fund's  total
assets  (including the amount borrowed) taken at market value. The Fund will not
use  leverage  to  attempt  to  increase  income.  The Fund  will  not  purchase
securities  while   outstanding   borrowings   (including   reverse   repurchase
agreements) exceed 5% of the Fund's total assets.

         (3) Pledge,  mortgage,  or  hypothecate  its  assets,  except to secure
indebtedness  permitted by paragraph  (2) above and then only if such  pledging,
mortgaging or  hypothecating  does not exceed 33 1/3% of the Fund's total assets
taken at market value.

         (4) Act as an  underwriter,  except to the extent that,  in  connection
with the  disposition of portfolio  securities,  the Fund may be deemed to be an
underwriter for purposes of the Securities Act of 1933.

         (5)  Purchase  or  sell  real  estate,  including  limited  partnership
interests,  except  that the Fund may invest in  securities  that are secured by
real estate or  interests  therein and may  purchase  and sell  mortgage-related
securities and may hold and sell real estate acquired by the Fund as a result of
the ownership of securities.

         (6) Make loans,  except that the Fund may lend portfolio  securities in
accordance  with the Fund's  investment  policies  and may purchase or invest in
repurchase  agreements,  bank  certificates  of deposit,  all or a portion of an


                                      B-9
<PAGE>

issue  of  publicly  distributed  bonds,  bank  loan  participation  agreements,
bankers'  acceptances,  debentures  or  other  securities,  whether  or not  the
purchase is made upon the original issuance of the securities.

         (7) Invest in commodities or commodity  contracts or in puts, calls, or
combinations  of both,  except  interest  rate  futures  contracts,  options  on
securities,  securities  indices,  currency  and  other  financial  instruments,
futures  contracts  on  securities,   securities  indices,  currency  and  other
financial  instruments  and options on such futures  contracts,  forward foreign
currency exchange contracts,  forward commitments,  securities index put or call
warrants and repurchase  agreements  entered into in accordance  with the Fund's
investment policies.

         The Fund  will  invest  25% or more of its total  assets in  securities
issued by companies in the real estate industry. Except as noted in the previous
sentence,  it is the  fundamental  policy  of the  Fund not to  concentrate  its
investments  in  securities  of companies  in any  particular  industry.  In the
opinion of the staff of the Securities and Exchange Commission,  investments are
concentrated in a particular  industry if such  investments (but not investments
in U.S. Government securities) aggregate 25% or more of the Fund's total assets.

         The Fund does not  intend to  invest  in or to enter  into any  forward
commitments,  forward foreign currency exchange  contracts,  reverse  repurchase
agreements,  options on securities or currency or securities  index put and call
warrants or to lend portfolio securities as described in fundamental  investment
restrictions (1), (2), (6) and (7) above, during the current fiscal year.

         In addition,  as a matter of  nonfundamental  investment  policy and in
connection  with the  offering  of its  shares in  various  states  and  foreign
countries, the Fund has agreed not to:

         (a) Participate on a joint-and-several  basis in any securities trading
account.  The  "bunching"  of  orders  for the sale or  purchase  of  marketable
portfolio  securities  with other  accounts  under the management of PMC to save
commissions  or to  average  prices  among  them is not  deemed  to  result in a
securities trading account.

         (b) Purchase  securities on margin or make short sales unless by virtue
of its ownership of other securities,  the Fund has the right to obtain, without
payment of additional consideration, securities equivalent in kind and amount to
the securities sold and, if the right is conditional,  the sale is made upon the
same conditions, except that a Fund may obtain such short-term credits as may be
necessary  for the  clearance  of  purchases  and  sales  of  securities  and in
connection  with  transactions   involving  forward  foreign  currency  exchange
transactions.

         (c)  Purchase  a  security  if, as a  result,  (i) more than 10% of the
Fund's  assets  would  be  invested  in  securities  of  closed-end   investment
companies,  (ii)  such  purchase  would  result  in more  than  3% of the  total
outstanding  voting  securities of any one such  closed-end  investment  company
being  held by the Fund,  or (iii) more than 5% of the  Fund's  assets  would be
invested in any one such closed-end investment company;  provided,  however, the
Fund  can  exceed  such  limitations  in  connection  with a plan of  merger  or
consolidation  with or acquisition of substantially all the assets of such other
closed-end investment company. The Fund will not invest in the securities of any


                                      B-10
<PAGE>

open-end  investment  company,  except  in  connection  with a plan of merger or
consolidation  with or acquisition of substantially all the assets of such other
open-end investment company.

         (d)  Purchase  securities  of  any  issuer  which,  together  with  any
predecessor,  has a record of less than three years' continuous operations prior
to the purchase if such purchase would cause investments of the Fund in all such
issuers to exceed 5% of the value of the total assets of the Fund.

         (e) Invest for the purpose of exercising  control over or management of
any company.

         (f) Purchase warrants of any issuer, if, as a result of such purchases,
more  than 2% of the value of the  Fund's  total  assets  would be  invested  in
warrants  which are not listed on the New York Stock  Exchange  or the  American
Stock  Exchange  or more than 5% of the  value of the  total  assets of the Fund
would be  invested in warrants  generally,  whether or not so listed.  For these
purposes,  warrants  are to be  valued  at the  lesser  of cost or  market,  but
warrants acquired by the Fund in units with or attached to debt securities shall
be deemed to be without value.

   
         (g) Knowingly purchase or retain securities of an issuer if one or more
of the  Trustees or officers of the Fund or  directors or officers of PMC or any
investment management subsidiary of PMC individually owns beneficially more than
0.5% and  together  own  beneficially  more  than 5% of the  securities  of such
issuer.
    

         (h)  Purchase  interests  in  oil,  gas  or  other  mineral  leases  or
exploration programs;  however, this policy will not prohibit the acquisition of
securities of companies engaged in the production or transmission of oil, gas or
other minerals.  These  restrictions  may not be changed without the approval of
the regulatory agencies in such states or foreign countries.

         (i)  Purchase  any   security,   including   stripped   mortgage-backed
securities and any repurchase  agreement maturing in more than seven days, which
is  illiquid,  if more than 15% of the net  assets of the Fund,  taken at market
value, would be invested in such securities.

         (j) Invest more than 10% of its total assets in restricted  securities,
excluding restricted  securities eligible for resale pursuant to Rule 144A under
the  Securities  Act of 1933;  provided,  however,  that no more than 15% of the
Fund's  total  assets  may  be  invested  in  restricted   securities  including
restricted securities eligible for resale under Rule 144A.

         (k) Write covered calls or put options with respect to more than 25% of
the value of its total  assets  or  invest  more than 5% of its total  assets in
puts, calls, spreads, or straddles, other than protective put options.

   
         (l) Invest  more than 10% of its total  assets in shares of real estate
investment trusts that are not readily marketable.

4.                ADVISORY SERVICES
    

   
                  As stated in the Prospectus, Pioneering Management Corporation
("PMC"), 60 State Street, Boston, Massachusetts, serves as the Fund's investment
adviser.  The  management  contract  expires on May 31, 1997 but it is renewable
annually  after such date by the vote of a majority  of the Board of Trustees of
the Fund  (including  a majority of the Board of Trustees who are not parties to
the  contract or  interested  persons of any such  parties)  cast in person at a
meeting  called  for the  purpose  of  voting  on such  renewal.  This  contract
terminates if assigned and may be terminated  without penalty by either party by
vote of its Board of  Directors  or Trustees  or a majority  of its  outstanding
voting securities and the giving of sixty days' written notice.

                  As  compensation  for its  investment  advisory and management
services and expenses incurred, PMC irs entitled to a management fee at the rate
of 1.00% per annum of the Fund's  average daily net assets.  The fee is normally
computed  daily and paid  monthly.  PMC has  voluntarily  agreed not to impose a
portion  of its  management  fee and to make  other  arrangements  to the extent
necessary to limit operating expenses of the Class A shares of the Fund to 1.75%


                                      B-16
<PAGE>

of the Fund's  average daily net assets;  the portion of the Fund-wide  expenses
attributable  to Class B or Class C shares  will be  reduced  only to the extent
they are reduced for Class A shares.  This  agreement is voluntary and temporary
and may be revised or terminated at any time. From the Fund's inception  through
July17,  1995, PWA served as investment adviser to the Fund and PMC and Winthrop
Advisers Limited Partnership  ("WALP") served as subadvisers to the Fund. During
the period that PWA served as adviser,  PWA  voluntarily  agreed not to impose a
portion  of its  management  fee and to make  other  arrangements  to the extent
necessary  to limit the Fund's  total  expenses  to 1.75% of the Fund's  average
daily net assets.

                  For the periods  October 25, 1993 through June 30, 1994,  July
1, 1994 through December 31, 1994 and January 1, 1995 through June 30, 1995, the
Fund  would  have paid or  accrued  total  management  fees to PWA of  $103,371,
$141,284  and  $130,341,  respectively,  but $45,812 and  $73,158,  and $107,417
respectively,  of such fee was not imposed pursuant to PWA's voluntary agreement
described above.

                  For the periods  July 1, 1994  through  December  31, 1994 and
January 1, 1995  through June 30, 1995,  PWA paid or accrued  total  subadvisory
fees to PMC and WALP approximately $26,010 and $26,010, respectively.

         PMC has agreed that if in any fiscal year the aggregate expenses of the
Fund exceed the expense limitation  established by any state having jurisdiction
over the Fund,  PWA will  reduce its  management  fee to the extent  required by
state law. The most restrictive state expense limit currently  applicable to the
Fund provides that the Fund's expenses in any fiscal year may not exceed 2.5% of
the first $30 million of average daily net assets,  2.0% of the next $70 million
of such assets and 1.5% of such assets in excess of $100  million.  In the past,
the relevant state has granted relief for real estate  investment funds, such as
the Fund, because of their higher operations costs, and the Fund expects to seek
such relief to the extent it becomes necessary to do so.

                  In an attempt to avoid any potential  conflict with  portfolio
transactions for the Fund, PMC and the Fund have adopted extensive  restrictions
on personal  securities  trading by personnel of PMC and its  affiliates.  These
restrictions include:  pre-clearance of all personal securities transactions and
a prohibition  of  purchasing  initial  public  offerings of  securities.  These
restrictions are a continuation of the basic principle that the interests of the
Fund and its shareholders come before those of PMC and its employees.

5.                UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS
    

                  The Fund and Pioneer Funds Distributor, Inc. are parties to an
Underwriting Agreement. See "Principal Underwriter" below. The Trustees who were
not at the time they voted  interested  persons  of the Fund,  as defined in the
1940 Act, approved the Underwriting  Agreement.  The Underwriting Agreement will
continue  from  year  to  year  if  annually  approved  by  the  Trustees.   The
Underwriting Agreement provides that PFD will bear certain distribution expenses
not borne by the Fund.

                  PFD bears all expenses it incurs in providing  services  under
the Underwriting Agreement.  Such expenses include compensation to its employees
and representatives and to securities dealers for distribution  related services


                                      B-17
<PAGE>

performed for the Fund.  PFD also pays certain  expenses in connection  with the
distribution of the Fund's shares, including the cost of preparing, printing and
distributing  advertising or promotional materials, and the cost of printing and
distributing prospectuses and supplements to prospective shareholders.  The Fund
bears the cost of registering its shares under federal and state securities law.

                  The Fund and PFD have agreed to indemnify  each other  against
certain liabilities,  including liabilities under the Securities Act of 1933, as
amended.  Under the  Underwriting  Agreement,  PFD will use its best  efforts in
rendering services to the Fund.

Class A Plan

   
         Pursuant  to the  Class  A Plan  the  Fund  may  reimburse  PFD for its
expenditures in financing any activity  primarily intended to result in the sale
of Fund shares.  Certain  categories of such  expenditures have been approved by
the Board of Trustees  and are set forth in the  Prospectus.  See  "Distribution
Plans" in the Prospectus.  The expenses of the Fund pursuant to the Class A Plan
are accrued on a fiscal year basis and may not exceed,  the annual rate of 0.25%
of the Fund's average daily net assets attributable to Class A.
    

Class B Plan

   
         The Class B Plan  provides  that the Fund will pay PFD,  as the  Fund's
distributor  for its Class B shares,  a distribution  fee accrued daily and paid
quarterly,  equal on an annual  basis to 0.75% of the Fund's  average  daily net
assets  attributable  to Class B shares and will pay PFD a service  fee equal to
0.25% of the  Fund's  average  daily net assets  attributable  to Class B shares
(which  PFD will in turn pay to  securities  dealers  which  enter  into a sales
agreement  with PFD at a rate of up to 0.25% of the  Fund's  average  daily  net
assets  attributable  to  Class B  shares  owned  by  investors  for  whom  that
securities  dealer  is the  holder or dealer of  record).  This  service  fee is
intended to be in consideration of personal services and/or account  maintenance
services rendered by the dealer with respect to Class B shares. PFD will advance
to dealers  the  first-year  service  fee at a rate equal to 0.25% of the amount
invested. As compensation  therefor,  PFD may retain the service fee paid by the
Fund with respect to such shares for the first year after  purchase.  Commencing
in the  thirteenth  month  following a purchase of Class B shares,  dealers will
become eligible for additional  service fees or other  compensation with respect
to such shares.  Dealers may from time to time be required to meet certain other
criteria in order to receive service fees. PFD or its affiliates are entitled to
retain all  service  fees  payable  under the Class B Plan for which there is no
dealer  of  record or for  which  qualification  standards  have not been met as
partial  consideration for personal services and/or account maintenance services
performed by PFD or its affiliates for shareholder accounts.

         The purpose of  distribution  payments to PFD under the Class B Plan is
to  compensate  PFD for its  distribution  services  with respect to the Class B
shares of the Fund.  PFD pays  commissions  to  dealers as well as  expenses  of
printing prospectuses and reports used for sales purposes, expenses with respect
to   the   preparation   and   printing   of   sales    literature   and   other
distribution-related expenses, including, without limitation, the cost necessary


                                      B-18
<PAGE>

to provide  distribution-related  services, or personnel, travel office expenses
and  equipment.  The Class B Plan also  provides that PFD will receive all CDSCs
attributable to Class B shares. (See "Distributions Plans" in the Prospectus.)
    

Class C Plan

   
         The Class C Plan  provides  that the Fund will pay PFD,  as the  Fund's
distributor  for its Class C shares,  a distribution  fee accrued daily and paid
quarterly,  equal on an annual  basis to 0.75% of the Fund's  average  daily net
assets  attributable  to Class C shares and will pay PFD a service  fee equal to
0.25% of the Fund's average daily net assets attributable to Class C shares. PFD
will in turn pay to securities  dealers which enter into a sales  agreement with
PFD a  distribution  fee and a service  fee at rates of up to 0.75%  and  0.25%,
respectively,  of the Fund's  average daily net assets  attributable  to Class C
shares  owned by  investors  for whom that  securities  dealer is the  holder or
dealer of record. The service fee is intended to be in consideration of personal
services and/or account maintenance services rendered by the dealer with respect
to Class C shares.  PFD will advance to dealers the first-year  service fee at a
rate equal to 0.25% of the amount invested.  As compensation  therefor,  PFD may
retain the  service  fee paid by the Fund with  respect  to such  shares for the
first year after  purchase.  Commencing  in the  thirteenth  month  following  a
purchase of Class C shares,  dealers will become eligible for additional service
fees at a rate of up to 0.25% of the amount invested and additional compensation
at a rate of up to 0.75% of the amount  invested  with  respect to such  shares.
Dealers  may from time to time be  required to meet  certain  other  criteria in
order to receive  service fees. PFD or its affiliates are entitled to retain all
service  fees  payable  under the  Class C Plan for which  there is no dealer of
record  or for  which  qualification  standards  have not  been  met as  partial
consideration  for  personal  services  and/or  account   maintenance   services
performed by PFD or its affiliates for shareholder accounts.

         The purpose of  distribution  payments to PFD under the Class C Plan is
to  compensate  PFD for its  distribution  services  with respect to the Class C
shares of the Fund.  PFD pays  commissions  to  dealers as well as  expenses  of
printing prospectuses and reports used for sales purposes, expenses with respect
to   the   preparation   and   printing   of   sales    literature   and   other
distribution-related expenses, including, without limitation, the cost necessary
to provide  distribution-related  services, or personnel, travel office expenses
and  equipment.  The Class C Plan also  provides that PFD will receive all CDSCs
attributable to Class C shares. (See "Distributions Plans" in the Prospectus.)
    

General

   
         In accordance with the terms of the Plans, PFD provides to the Fund for
review by the Trustees a quarterly  written report of the amounts expended under
the respective  Plan and the purpose for which such  expenditures  were made. In
the Trustees'  quarterly  review of the Plans,  they will consider the continued
appropriateness  and the  level  of  reimbursement  or  compensation  the  Plans
provide.

         No  interested  person of the Fund,  nor any Trustee of the Fund who is
not an  interested  person of the Fund,  has any  direct or  indirect  financial
    


                                      B-19
<PAGE>

   
interest in the operation of the Plans except to the extent that PFD and certain
of its employees may be deemed to have such an interest as a result of receiving
a portion of the amounts  expended under the Plans by the Fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.
    

   
         The Plans were  adopted by a  majority  vote of the Board of  Trustees,
including  all of the Trustees who are not, and were not at the time they voted,
interested  persons of the Fund, as defined in the 1940 Act (none of whom had or
have any direct or indirect  financial  interest in the operation of the Plans),
cast in person at a meeting  called for the  purpose of voting on the Plans.  In
approving  the  Plans,  the  Trustees  identified  and  considered  a number  of
potential  benefits which the Plans may provide.  The Board of Trustees believes
that there is a reasonable  likelihood  that the Plans will benefit the Fund and
their current and future  shareholders.  Under their terms,  the Plans remain in
effect from year to year provided such continuance is approved  annually by vote
of the Trustees in the manner  described  above. The Plans may not be amended to
increase materially the annual percentage limitation of average net assets which
may be  spent  for  the  services  described  therein  without  approval  of the
shareholders of the Class or Classes affected thereby,  and material  amendments
of the Plans must also be  approved  by the  Trustees  in the  manner  described
above. A Plan may be terminated at any time, without payment of any penalty,  by
vote of the majority of the Trustees who are not interested  persons of the Fund
and have no direct or indirect financial interest in the operations of the Plan,
or by a  vote  of "a  majority  of the  outstanding  voting  securities"  of the
respective  Class  of the  Fund  (as  defined  in the  1940  Act).  A Plan  will
automatically terminate in the event of its "assignment" (as defined in the 1940
Act).

                  During the period  October 25, 1993 through June 30, 1994, the
Fund did not incur any distribution  fees pursuant to the Class A Plan. The Fund
commenced accruing  distribution and service fees under the Class A Plan on July
1, 1994.  For the periods July 1, 1994 through  December 31, 1994 and January 1,
1995 through June 30, 1995, the Fund incurred total Class A distribution fees of
$35,321  and  $  32,585,  respectively.  Such  fees  will  be  paid  to  PFD  in
reimbursement of expenses  related to servicing of Class A shareholder  accounts
and to compensating  dealers and sales personnel.  The Fund has not incurred any
distribution fees pursuant to the Class B and Class C Plans. Class B and Class C
shares will first be offered in 1996.


6.                SHAREHOLDER SERVICING/TRANSFER AGENT
    

                  The Fund has contracted with Pioneering  Services  Corporation
("PSC"), 60 State Street, Boston, Massachusetts, to act as shareholder servicing
agent and transfer agent for the Fund. This contract  terminates if assigned and
may be  terminated  without  penalty  by  either  party by vote of its  Board of
Directors or Trustees or a majority of its outstanding voting securities and the
giving of ninety days' written notice.

                  Under  the  terms  of its  contract  with the  Fund,  PSC will
service shareholder accounts, and its duties will include: (i) processing sales,
redemptions and exchanges of shares of the Fund; (ii) distributing dividends and
capital gains  associated with Fund portfolio  accounts;  and (iii)  maintaining
account records and responding to routine shareholder inquiries.

                                      B-20
<PAGE>

   
                  PSC  receives  from the Fund an annual  fee of $22.00 for each
Class  A,  Class B and  Class C  shareholder  account  as  compensation  for the
services  described above.  This fee is set at an amount determined by vote of a
majority  of the  Trustees  (including  a majority of the  Trustees  who are not
parties to the contract with PSC or  interested  persons of any such parties) to
be  comparable  to  fees  for  such  services  being  paid by  other  investment
companies.

7.                CUSTODIAN
    

                  Brown  Brothers  Harriman  &  Co.  (the  "Custodian")  is  the
custodian  of  the  Fund's  assets.  The  Custodian's  responsibilities  include
safekeeping  and controlling the Fund's cash and securities in the United States
as  well  as  in  foreign  countries,  handling  the  receipt  and  delivery  of
securities, and collecting interest and dividends on the Fund's investments. The
Custodian  fulfills  its  function  in  foreign  countries  through a network of
subcustodian banks located in the foreign countries (the "Subcustodians").

                  The Custodian  does not determine the  investment  policies of
the Fund or decide which  securities it will buy or sell. The Fund may invest in
securities issued by the Custodian,  deposit cash in the Custodian and deal with
the Custodian as a principal in securities  transactions.  Portfolio  securities
may be deposited into the Federal Reserve-Treasury  Department Book Entry System
or the  Depository  Trust Company in the United States or in recognized  central
depositories in foreign countries.

   
8.                PRINCIPAL UNDERWRITER
    

                  Pioneer Funds  Distributor,  Inc.,  60 State  Street,  Boston,
Massachusetts,  serves as the principal  underwriter  for the Fund in connection
with the continuous  offering of its shares.  The Fund will not generally  issue
Fund shares for  consideration  other than cash. At the Fund's sole  discretion,
however,  it may  issue  Fund  shares  for  consideration  other  than  cash  in
connection with an acquisition of portfolio  securities  pursuant to a bona fide
purchase of assets,  merger or  reorganization  provided (i) securities meet the
investment objectives and policies of the Fund; (ii) the securities are acquired
by the Fund for  investment  and not for resale;  (iii) the  securities  are not
restricted  as to transfer  either by law or liquidity  of market;  and (iv) the
securities have a value which is readily ascertainable (and not established only
by  evaluation  procedures)  as  evidenced  by a listing on the  American  Stock
Exchange  or the New  York  Stock  Exchange,  or by  quotation  under  the  NASD
Automated  Quotation  System.  An  exchange of  securities  for Fund shares will
generally be a taxable transaction to the shareholder.

   
                  The redemption  price of shares of beneficial  interest of the
Fund may, at PMC's discretion, be paid in cash or portfolio securities. The Fund
has,  however,  elected to be governed by Rule 18f-1 under the 1940 Act pursuant
to which the Fund is obligated to redeem  shares solely in cash up to the lesser
of $250,000 or 1% of the Fund's net asset value during any 90-day period for any
one shareholder. Should the amount of redemptions by any shareholder exceed such
limitation,  the Fund will have the  option of  redeeming  the excess in cash or
portfolio  securities.  In the latter case,  the  securities  are taken at their
value  employed in determining  the Fund's net asset value. A shareholder  whose


                                      B-21
<PAGE>

shares  are  redeemed  in-kind  may  incur  brokerage  charges  in  selling  the
securities  received  in-kind.  The selection of such securities will be made in
such manner as the Board deems fair and reasonable.

                  During the periods  from  October 25,  1993  through  June 30,
1994,  July 1, 1994  through  December 31, 1994 and January 1, 1995 through June
30, 1995,  net  underwriting  commissions  earned by PFD in connection  with its
offering of Fund shares were approximately $66,304, $27,497 and $15,000. For the
same  periods,  commissions  reallowed  to  dealers  by PFD  were  approximately
$1,124,000, $186,213 and $103,000, respectively.

9.                INDEPENDENT PUBLIC ACCOUNTANTS
    

                  Arthur   Andersen  LLP  is  the  Fund's   independent   public
accountant,  providing  audit  services,  tax return review,  and assistance and
consultation with respect to the preparation of filings with the Commission.

   
10.               PORTFOLIO TRANSACTIONS

                  All orders for the  purchase or sale of  portfolio  securities
are placed on behalf of the Fund by PMC pursuant to  authority  contained in the
Investment  Advisory  Contract  with PMC. In selecting  brokers or dealers,  PMC
considers other factors relating to best execution,  including,  but not limited
to,  the size and type of the  transaction;  the  nature  and  character  of the
markets of 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.  Most  transactions in foreign equity securities are executed by
broker-dealers  in foreign  countries in which  commission  rates are fixed and,
therefore,  are not  negotiable (as such rates are in the United States) and are
generally higher than in the United States.

                  PMC may select dealers which provide brokerage and/or research
services to the Fund and/or other  investment  companies or accounts  managed by
PMC. 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;  furnishing  analyses
and reports concerning  issuers,  industries,  securities,  economic factors and
trends, portfolio strategy and performance of accounts; and effecting securities
transactions and performing  functions incidental thereto (such as clearance and
settlement).  PMC  maintains a listing of dealers who provide such services on a
regular  basis.  However,  because many  transactions  on behalf of the Fund and
other  investment  companies or accounts  managed by PMC are placed with dealers
(including  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.  Management
believes that no exact dollar value can be calculated for such services.
    

                                      B-22
<PAGE>

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

                  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 the  Fund as well as  shares  of  other  investment
companies or accounts managed by PMC. This policy does not imply a commitment to
execute all portfolio  transactions  through all broker-dealers that sell shares
of the Fund.  In addition,  if PMC  determines  in good faith that the amount of
commissions  charged by a broker 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 in an amount greater than the amount another firm may
charge.
    

                  The  Trustees  periodically  review PMC's  performance  of its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Fund.

   
                  In addition to serving as  investment  subadviser to the Fund,
PMC acts as  investment  adviser to other mutual funds in the Pioneer  group and
private  accounts with  investment  objectives  similar to those of the Fund. As
such,  securities may meet  investment  objectives of the Fund, such other funds
and such private accounts.  In such cases, the decision to recommend to purchase
for one fund or account rather than another is based on a number of factors. The
determining  factors in most cases are the  amount of  securities  of the issuer
then  outstanding,  the value of those securities and the market for them. Other
factors considered in the investment  recommendations  include other investments
which each fund or account presently has in a particular industry or country and
the availability of investment funds in each fund or account.
    

                  It is possible that, at times,  identical  securities  will be
held by more than one fund and/or account.  However, the position of any fund or
account  in the same  issue  may vary and the  length  of time  that any fund or
account may choose to hold its  investment in the same issue may likewise  vary.
To the extent  that the Fund,  another  fund in the  Pioneer  group or a private
account  managed by PMC seeks to  acquire  the same  security  at about the same
time,  the Fund may not be able to acquire as large a position in such  security
as it desires or it may have to pay a higher price for the security.  Similarly,
the Fund may not be able to obtain as large an  execution of an order to sell or
as high a price for any particular  portfolio security if PMC decides to sell on
behalf of another  account the same portfolio  security at the same time. On the
other hand, if the same  securities  are bought or sold at the same time by more
than one account,  the  resulting  participation  in volume  transactions  could
produce better executions for the Fund or other account.  In the event that more


                                      B-23
<PAGE>

than one account  purchases  or sells the same  security  on a given  date,  the
purchases and sales will normally be made as nearly as practicable on a pro rata
basis in proportion to the amounts desired to be purchased or sold by each.

   
                  During the periods  from  October 25,  1993  through  June 30,
1994,  July 1, 1994  through  December 31, 1994 and January 1, 1995 through June
30,  1995,  the  Fund  paid or  accrued  aggregate  brokerage  and  underwriting
commissions of approximately $170,534, $213,710 and $118,000, respectively.
    

   
11.               TAX STATUS
    

                  It is the Fund's policy to meet the requirements of Subchapter
M of the Code for qualification as a regulated  investment  company. If the Fund
meets  all  such  requirements  and  distributes  to its  shareholders  at least
annually all  investment  company  taxable  income and net capital gain, if any,
which it receives,  the Fund will be relieved of the necessity of paying federal
income tax.

                  In order to qualify as a regulated  investment  company  under
Subchapter  M, the Fund must,  among  other  things,  derive at least 90% of its
annual  gross  income  from  dividends,  interest,  gains from the sale or other
disposition  of  stock,  securities  or  foreign  currencies,  or  other  income
(including  gains from  options,  futures and forward  contracts)  derived  with
respect to its  business of investing in such stock,  securities  or  currencies
(the "90% income  test"),  limit its gains from the sale of certain  investments
held for less than three months to less than 30% of its annual gross income (the
"30%   test")  and   satisfy   certain   annual   distribution   and   quarterly
diversification requirements.

                  Dividends from net investment  income,  net short-term capital
gains,  and certain net foreign  exchange gains are taxable as ordinary  income,
whether received in cash or in additional  shares.  Dividends from net long-term
capital  gains,  if any,  whether  received in cash or  additional  shares,  are
taxable to the Fund's shareholders as long-term capital gains for Federal income
tax purposes  without  regard to the length of time shares of the Fund have been
held.  The federal  income tax status of all  distributions  will be reported to
shareholders annually.

                  Any  dividend  declared  by the Fund in  October,  November or
December  as of a record  date in such a month  and paid  during  the  following
January  will be  treated  for  federal  income  tax  purposes  as  received  by
shareholders on December 31 of the calendar year in which it is declared.

                  For purposes of the 70% dividends-received deduction available
to  corporations,  dividends  received by the Fund, if any,  from U.S.  domestic
corporations  in respect of any share of stock with a tax  holding  period of at
least 46 days (91 days in the case of certain preferred stock) in an unleveraged
position and distributed and designated by the Fund may be treated as qualifying
dividends.  Any corporate  shareholder  should consult its tax adviser regarding
the  possibility  that its tax basis in its shares may be  reduced,  for federal
income  tax  purposes,  by reason of  "extraordinary  dividends"  received  with
respect to the shares.  Corporate  shareholders  must meet the  minimum  holding
period  requirement  stated  above  (46 or 91 days),  taking  into  account  any


                                      B-24
<PAGE>

holding-period  reductions  from  certain  hedging  or other  transactions  that
diminish risk of loss, with respect to their Fund shares in order to qualify for
the  deduction  and,  if they  borrow to acquire  Fund  shares,  may be denied a
portion of the  dividends-received  deduction.  The entire qualifying  dividend,
including the otherwise  deductible amount,  will be included in determining the
excess  (if  any)  of  a  corporation's   adjusted  current  earnings  over  its
alternative   minimum  taxable  income,   which  may  increase  a  corporation's
alternative minimum tax liability.

                  The Fund may be subject to withholding and other taxes imposed
by  foreign  countries  with  respect to  investments  in those  countries.  Tax
conventions  between certain countries and the U.S. may reduce or eliminate such
taxes.  The Fund will not  satisfy  the  requirements  for  passing  through  to
shareholders  their pro rata shares of foreign taxes paid by the Fund,  with the
result that its shareholders  will not include such taxes in their gross incomes
and will not be  entitled to a tax  deduction  or credit for such taxes on their
own tax returns.

                  Foreign  exchange  gains and  losses  realized  by the Fund in
connection with certain  transactions  involving foreign  currency-  denominated
debt securities, foreign currencies, or payables or receivables denominated in a
foreign  currency are subject to Section 988 of the Code, which generally causes
such gains and losses to be treated as ordinary income and losses and may affect
the amount, timing and character of distributions to shareholders.

                  If  the  Fund   acquires   the  stock  of   certain   non-U.S.
corporations that receive at least 75% of their annual gross income from passive
sources (such as sources that produce  interest,  dividend,  rental,  royalty or
capital  gain  income)  or hold at least  50% of their  assets  in such  passive
sources ("passive foreign investment  companies"),  the Fund could be subject to
Federal income tax and  additional  interest  charges on "excess  distributions"
received from such  companies or gain from the sale of stock in such  companies,
even if all income or gain actually  received by the Fund is timely  distributed
to its  shareholders.  The  Fund  would  not be  able  to  pass  through  to its
shareholders  any  credit or  deduction  for such a tax.  In certain  cases,  an
election may be available that would ameliorate these adverse tax  consequences.
The Fund may limit its investments in passive foreign  investment  companies and
will undertake  appropriate  actions,  including  consideration of any available
elections,  to limit its tax liability,  if any, or take other defensive  action
with respect to such investments.

                  Investment  in  debt  obligations  that  are at  risk of or in
default  presents  special tax issues for the Fund.  Tax rules are not  entirely
clear about issues such as when the Fund may cease to accrue interest,  original
issue  discount or market  discount,  when and to what extent  deductions may be
taken  for  bad  debts  or  worthless  securities,   how  payments  received  on
obligations in default  should be allocated  between  principal and income,  and
whether  exchanges of debt  obligations in a workout context are taxable.  These
and other issues will be addressed by the Fund,  in the event it invests in such
securities, in order to ensure that it distributes sufficient income to preserve
its status as a regulated  investment  company and to avoid becoming  subject to
federal income or excise tax.

                  Since, at the time of an investor's purchase of Fund shares, a
portion  of the per  share  net  asset  value by  which  the  purchase  price is
determined  may be  represented  by realized or unrealized  appreciation  in the
Fund's  portfolio  or  undistributed  taxable  income  of the  Fund,  subsequent


                                      B-25
<PAGE>

distributions  (or  portions  thereof)  on such  shares  may be  taxable to such
investor  even if the net  asset  value of his  shares  is,  as a result  of the
distributions,  reduced below his cost for such shares and the distributions (or
portions thereof) in reality represent a return of a portion of his investment.

                  Any loss  realized  upon the  redemption  of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term  capital gain
with respect to such shares.

                  In addition,  if shares  redeemed or exchanged  have been held
for less than 91 days, (a) in the case of a reinvestment  at net asset value the
sales  charge paid on such  shares is not  included in their tax basis under the
Code  if a  reinvestment  occurs,  and (2) in a case  of an  exchange,  all or a
portion of the sales  charge  paid on such  shares is not  included in their tax
basis under the Code, to the extent a sales charge that would otherwise apply to
the shares  received is reduced  pursuant to the exchange  privilege.  In either
case,  the  portion  of the sales  charge not  included  in the tax basis of the
shares  redeemed or  surrendered  in an exchange is included in the tax basis of
the  shares  acquired  in  the  reinvestment  or  exchange.  Losses  on  certain
redemptions  may be  disallowed  under  "wash  sale" rules in the event of other
investments  in the Fund  within 30 days before or after a  redemption  or other
sale of shares.

                  For Federal  income tax  purposes,  the Fund is  permitted  to
carry forward a net realized capital loss in any year to offset realized capital
gains,  if any,  during the eight years  following  the year of the loss. To the
extent  subsequent  net realized  capital gains are offset by such losses,  they
would  not  result  in  Federal  income  tax  liability  to the Fund and are not
expected to be distributed as such to shareholders.

                  Different tax treatment, including penalties on certain excess
contributions  and  deferrals,   certain   pre-retirement  and   post-retirement
distributions,  and  certain  prohibited  transactions,  is accorded to accounts
maintained as qualified retirement plans.  Shareholders should consult their tax
advisers for more information.

                  Provided  that the Fund  qualifies  as a regulated  investment
company ("RIC") under the Code, it will not be required to pay any Massachusetts
income, corporate excise or franchise taxes. Provided that the Fund qualifies as
a RIC and meets certain income source  requirements under Delaware Law, the Fund
should also not be required to pay Delaware corporation income tax.

   
                  Options  written or purchased  and futures  contracts  entered
into by the Fund on certain securities and securities indices may cause the Fund
to recognize  gains or losses from  marking-to-market  at the end of its taxable
year even though such options may not have lapsed, been closed out, or exercised
or such  futures  contracts  may not have been closed out or disposed of and may
affect the characterization as long-term or short-term of some capital gains and
losses  realized  by the Fund.  Losses on certain  options or futures  contracts
and/or  offsetting  positions  (portfolio  securities  or other  positions  with
respect to which the Fund's risk of loss is  substantially  diminished by one or
more options or futures  contracts)  may also be deferred under the tax straddle
    


                                      B-26
<PAGE>

rules of the Code, which may also affect the  characterization  of capital gains
or losses from straddle  positions and certain successor  positions as long-term
or short-term.  The tax rules  applicable to options,  futures and straddles may
affect the amount,  timing and character of the Fund's income and loss and hence
of its distributions to shareholders.

                  Federal  law  requires  that the  Fund  withhold  (as  "backup
withholding")  31% of reportable  payments,  including  dividends,  capital gain
dividends,   and  the  proceeds  of   redemptions   (including   exchanges)  and
repurchases,  to  shareholders  who have not complied with IRS  regulations.  In
order to avoid this withholding requirement,  shareholders must certify on their
Account  Applications,  or on separate  W-9 Forms,  that the Social  Security or
other  Taxpayer  Identification  Number they provide is their correct number and
that they are not  currently  subject  to backup  withholding,  or that they are
exempt  from  backup  withholding.  The Fund may  nevertheless  be  required  to
withhold if it receives notice from the IRS or a broker that the number provided
is  incorrect  or backup  withholding  is  applicable  as a result  of  previous
underreporting of interest or dividend income.

                  The description  above relates only to U.S. federal income tax
consequences  for  shareholders  who are U.S.  persons,  i.e., U.S.  citizens or
residents and U.S. domestic corporations,  partnerships,  trusts or estates, and
who are subject to U.S.  federal  income tax. The  description  does not address
special tax rules applicable to certain classes of investors, such as tax-exempt
entities,  insurance companies, and financial institutions.  Shareholders should
consult  their own tax advisers on these  matters and on state,  local and other
applicable  tax laws.  Investors  other  than U.S.  persons  may be  subject  to
different U.S. tax treatment,  including a possible 30% U.S. withholding tax (or
withholding tax at a lower treaty rate) on dividends treated as ordinary income.

   
12.               DESCRIPTION OF SHARES

         The  Fund's  Declaration  of Trust  permits  the Board of  Trustees  to
authorize the issuance of an unlimited  number of full and fractional  shares of
beneficial  interest  which  may be  divided  into such  separate  series as the
Trustees may  establish.  Currently,  the Fund consists of only one series.  The
Trustees may, however,  establish additional series of shares in the future, and
may divide or  combine  the  shares  into a greater  or lesser  number of shares
without thereby changing the proportionate beneficial interests in the Fund. The
Declaration  of Trust further  authorizes the Trustees to classify or reclassify
any  series  of the  shares  into one or more  classes.  Pursuant  thereto,  the
Trustees  have  authorized  the issuance of three classes of shares of the Fund,
designated as Class A, Class B and Class C shares.  Each share of a class of the
Fund  represents  an equal  proportionate  interest  in the  assets  of the Fund
allocable to that class.  Upon  liquidation  of the Fund,  shareholders  of each
class of the Fund  are  entitled  to share  pro rata in the  Fund's  net  assets
allocable to such class  available for  distribution to  shareholders.  The Fund
reserves the right to create and issue  additional  series or classes of shares,
in which case the shares of each class of a series would participate  equally in
the  earnings,  dividends and assets  allocable to that class of the  particular
series.
    

                                      B-27
<PAGE>

   
         Shareholders  are entitled to one vote for each share held and may vote
in the  election  of Trustees  and on other  matters  submitted  to a meeting of
shareholders.  Although  Trustees are not elected annually by the  shareholders,
shareholders have, under certain circumstances,  the right to remove one or more
Trustees.

         The  series of the Fund are  entitled  to vote  separately  to  approve
investment  advisory  agreements  or changes  in  investment  restrictions,  but
shareholders  of all series  vote  together in the  election  and  selection  of
Trustees  and  accountants.  Shares of all  series or  classes  of the Fund vote
together as a class on matters  that affect all series or classes of the Fund in
substantially the same manner. As to matters affecting a single series or class,
shares of such  series or class will vote  separately.  No  amendment  adversely
affecting the rights of  shareholders  may be made to the Fund's  Declaration of
Trust without the affirmative  vote of a majority of its shares.  Shares have no
preemptive or conversion rights. Shares are fully paid and non-assessable by the
Fund, except as stated below.
    

   
13.               CERTAIN LIABILITIES

                  As a  Delaware  business  trust,  the  Fund's  operations  are
governed by its Agreement and  Declaration of Trust dated March 10, 1995, a copy
of which has been filed with the Fund's registration statement.
    

                  Generally,   Delaware  business  trust  shareholders  are  not
personally  liable for obligations of the Delaware business trust under Delaware
law.  The Delaware  Business  Trust Act (the  "Delaware  Act")  provides  that a
shareholder  of a  Delaware  business  trust  shall  be  entitled  to  the  same
limitation  of  liability   extended  to  shareholders  of  private   for-profit
corporations.  The Fund's Agreement and Declaration of Trust expressly  provides
that the Fund has been  organized  under the Delaware Act and that the Agreement
and  Declaration of Trust is to be governed by Delaware law. It is  nevertheless
possible that a Delaware  business trust, such as the Fund, might become a party
to an action in another  state whose courts  refused to apply  Delaware  law, in
which case the trust's shareholders could be subject to personal liability.

                  To guard against this risk,  the Agreement and  Declaration of
Trust (i) contains an express  disclaimer of  shareholder  liability for acts or
obligations of the Fund and provides that notice of such disclaimer may be given
in each  agreement,  obligation and  instrument  entered into or executed by the
Fund or its Trustees, (ii) provides for the indemnification out of Fund property
of any  shareholders  held personally  liable for any obligations of the Fund or
any series of the Fund and (iii)  provides  that the Fund shall,  upon  request,
assume the  defense of any claim made  against  any  shareholder  for any act or
obligation  of the Fund and satisfy any judgment  thereon.  Thus,  the risk of a
Fund shareholder  incurring  financial loss beyond his or her investment because
of  shareholder  liability  is  limited  to  circumstances  in which  all of the
following  factors are present:  (1) a court refused to apply  Delaware law; (2)
the  liability  arose under tort law or, if not, no  contractual  limitation  of
liability  was in effect;  and (3) the Fund  itself  would be unable to meet its
obligations. In light of Delaware law, the nature of the Fund's business and the
nature of its assets,  the risk of personal  liability to a Fund  shareholder is
remote.

                                      B-28
<PAGE>

                  The Agreement and  Declaration of Trust further  provides that
the Fund shall indemnify each of its Trustees and officers  against  liabilities
and expenses reasonably incurred by them, in connection with, or arising out of,
any action,  suit or proceeding,  threatened against or otherwise involving such
Trustee or officer,  directly or indirectly, by reason of being or having been a
Trustee or officer of the Fund. The Agreement and  Declaration of Trust does not
authorize the Fund to indemnify any Trustee or officer  against any liability to
which  he or she  would  otherwise  be  subject  by  reason  of or  for  willful
misfeasance,  bad faith, gross negligence or reckless disregard of such person's
duties.

   
14.               DETERMINATION OF NET ASSET VALUE

                  The net asset  value  per  share of each  Class of the Fund is
determined  as of the close of regular  trading  (currently  4:00 p.m.,  Eastern
Time) on each day on which the New York Stock Exchange (the  "Exchange") is open
for regular trading. As of the date of this Statement of Additional Information,
the  Exchange  is open  for  trading  every  weekday  except  for the  following
holidays:   New  Year's  Day,  Presidents'  Day,  Good  Friday,   Memorial  Day,
Independence  Day, Labor Day,  Thanksgiving Day and Christmas Day. The net asset
value per share of each Class of the Fund is also determined on any other day in
which the level of trading in its portfolio  securities is sufficiently  high so
that the  current  net asset  value per share  might be  materially  affected by
changes in the value of its  portfolio  securities.  The Fund is not required to
determine  its net asset value per share on any day in which no purchase  orders
for the  shares of the Fund  become  effective  and no shares are  tendered  for
redemption.
    

   
                  The net asset  value  per  share of each  Class of the Fund is
computed by taking the value of all of the Class's assets, less its liabilities,
and dividing it by the number of outstanding shares for that Class.  Expenses of
the Fund are  accrued  daily.  Securities  which  have not traded on the date of
valuation or securities  for which sales prices are not  generally  reported are
valued at the mean between the last bid and asked prices.  Securities  for which
no market quotations are readily available (including those the trading of which
has been  suspended) will be valued at fair value as determined in good faith by
the Board of Trustees,  although the actual  computations may be made by persons
acting  pursuant to the direction of the Board.  The maximum  offering price per
Class A share is the net asset value per Class A share,  plus the maximum  sales
charge.  Class  B and  Class  C are  offered  at net  asset  value  without  the
imposition  of an initial  sales  charge,  but are subject to a CDSC.  See "Fund
Share Alternatives" in the Prospectus.
    

15.               SYSTEMATIC WITHDRAWAL PLAN

   
                  The Systematic  Withdrawal Plan ("SWP") is designed to provide
a convenient method of receiving fixed payments at regular intervals from shares
of the Fund  deposited by the  applicant  under this Plan.  The  applicant  must
deposit or purchase for deposit with PSC shares of the Fund having a total value
of not less  than  $10,000.  Periodic  checks of $50 or more will be sent to the
applicant,  or any person  designated by him, monthly or quarterly.  Withdrawals
    


                                      B-29
<PAGE>

from Class B share  accounts  are  limited to 10% of the value of the account at
the time the SWP is  implemented.  A  designation  of a third  party to  receive
checks requires an acceptable signature guarantee.

                  Any income dividends or capital gains  distributions on shares
under the Systematic Withdrawal Plan will be credited to the Plan account on the
payment date in full and  fractional  shares at the net asset value per share in
effect on the record date.

   
                  Systematic Withdrawal Plan payments are made from the proceeds
of the redemption of shares  deposited under the Plan in a Plan account.  To the
extent that such  redemptions  for periodic  withdrawals  exceed dividend income
reinvested in the Plan account,  such redemptions will reduce and may ultimately
exhaust the number of shares  deposited  in the Plan  account.  Redemptions  are
taxable  transactions to  shareholders.  In addition,  the amounts received by a
shareholder  cannot be  considered  as an  actual  yield or income on his or her
investment  because  part  of  such  payments  may  be a  return  of  his or her
investment.
    

                  The Systematic  Withdrawal  Plan may be terminated at any time
(1) by written notice to PSC or from PSC to the shareholder; (2) upon receipt by
PSC of appropriate  evidence of the shareholder's  death; or (3) when all shares
under the Plan have been redeemed.
       

   
16.               LETTER OF INTENTION

                  Purchases  in the  Fund of  $50,000  or more of Class A shares
(excluding any reinvestments of dividends and capital gains  distributions) made
within a 13-month period pursuant to a Letter of Intention  provided by PFD will
qualify for a reduced sales charge. Such reduced sales charge will be the charge
that would be applicable to the purchase of all Class A shares  purchased during
such  13-month  period  pursuant to a Letter of  Intention  had such shares been
purchased  all at once.  See "How to Buy Fund  Shares"  in the  Prospectus.  For
example,  a  person  who  signs a  Letter  of  Intention  providing  for a total
investment  in Fund Class A shares of $50,000  over a 13-month  period  would be
charged at the 4.50% sales charge rate with respect to all purchases during that
period.  Should the amount actually purchased during the 13-month period be more
or less than that  indicated in the Letter,  an  adjustment  in the sales charge
will be made.  A purchase  not made  pursuant  to a Letter of  Intention  may be
included thereafter if the Letter is filed within 90 days of such purchase.  Any
shareholder  may also obtain the reduced sales charge by including the value (at
current  offering  price) of all his  shares  in the Fund and all other  Pioneer
open-end mutual funds,  except direct purchases of the Class A shares of Pioneer
Money Market Trust,  held of record as of the date of his Letter of Intention as
a credit toward determining the applicable scale of sales charge for the Class A
shares to be purchased under the Letter of Intention.
    

                  The  Letter of  Intention  authorizes  PSC to  escrow  Class A
shares  having a  purchase  price  equal to 5% of the stated  investment  in the
Letter of Intention.  A Letter of Intention is not a binding obligation upon the
investor to purchase,  or the Fund to sell,  the full amount  indicated  and the
investor should read the provisions of the Letter of Intention  contained in the
Account Application carefully before signing.

17.               INVESTMENT RESULTS
    

                  One  of  the  primary  methods  used  to  measure  the  Fund's
performance  is "total  return."  "Total  return" will  normally  represent  the
percentage change in value of an account, or of a hypothetical investment in the
Fund, over any period up to the lifetime of the Fund. Total return  calculations
will  usually  assume  the  reinvestment  of all  dividends  and  capital  gains
distributions and will be expressed as a percentage increase or decrease from an
initial value, for the entire period or for one or more specified periods within
the entire period.  Total return  percentages  for periods of less than one year
will usually be annualized; total return percentages for periods longer than one
year will  usually be  accompanied  by total  return  percentages  for each year
within the period and/or by the average annual  compounded  total return for the
period. The income and capital components of a given return may be separated and
portrayed  in  a  variety  of  ways  in  order  to  illustrate   their  relative
significance.  Performance  may also be portrayed in terms of cash or investment
values,  without  percentages.  Past performance cannot guarantee any particular
future result.

                  The Fund's yield  quotations  and average  annual total return
quotations as they may appear in the  Prospectus,  this  Statement of Additional
Information or in advertising are calculated by standard  methods  prescribed by
the Commission.

   
                  Standardized  Yield  Quotations.  The yield for each  Class of
Fund shares is computed by dividing the Class's net investment  income per share
during a base period of 30 days, or one month, by the maximum offering price per
share of the Class on the last day of such base  period in  accordance  with the
following formula:

                                                  a-b
                                    YIELD = 2[ ( ----- +1)6 -1]
                                                   cd

         Where:     a   =   interest earned during the period

                    b   =   net expenses accrued for the period

                    c   =   the average daily number of shares outstanding
                            during the period that were entitled
                            to receive dividends

                    d   =   the maximum offering price per share on the
                            last day of the period
    

         For purposes of  calculating  interest  earned on debt  obligations  as
provided in item "a" above:

         (i) The  yield  to  maturity  of each  obligation  held by the  Fund is
computed based on the market value of the obligation  (including  actual accrued
interest,  if any) at the close of  business  each day during  the  30-day  base


                                      B-31
<PAGE>

period, or, with respect to obligations purchased during the month, the purchase
price (plus  actual  accrued  interest,  if any) on  settlement  date,  and with
respect to obligations sold during the month the sale price (plus actual accrued
interest, if any) between the trade and settlement dates.

         (ii) The yield to maturity of each  obligation  is then  divided by 360
and the resulting  quotient is multiplied by the market value of the  obligation
(including actual accrued interest,  if any) to determine the interest income on
the obligation for each day. The yield to maturity  calculation has been made on
each obligation during the 30-day base period.

         (iii) Interest earned on all debt obligations  during the 30-day or one
month period is then totaled.

         (iv) The maturity of an obligation with a call provision(s) is the next
call date on which the obligation reasonably may be expected to be called or, if
none, the maturity date.

         With  respect to the  treatment  of discount and premium on mortgage or
other receivables-backed obligations which are expected to be subject to monthly
payments of principal and interest ("pay downs"),  the Fund accounts for gain or
loss  attributable  to actual  monthly  pay downs as an  increase or decrease to
interest  income  during  the  period.  In  addition,  the Fund may elect (i) to
amortize the discount or premium  remaining on a security,  based on the cost of
the security,  to the weighted  average  maturity  date, if such  information is
available,  or to the remaining  term of the security,  if the weighted  average
maturity date is not available,  or (ii) not to amortize the remaining  discount
or premium on a security.

   
         The Fund's Class A  standardized  yield was for the 30-day  period from
January 1, 1995  through  June 30,  1995 was x.xx%.  Assuming  no fee or expense
reduction,  the Fund's Class A standardized yield for the same period would have
been  x.xx%.  No Class B or Class C shares  were  outstanding  prior to January,
1996.

         Standardized  Average  Annual Total Return  Quotations.  Average annual
total  return  quotations  for each Class of Fund shares are computed by finding
the average  annual  compounded  rates of return that would cause a hypothetical
investment made on the first day of a designated  period (assuming all dividends
and  distributions  are reinvested) to equal the ending redeemable value of such
hypothetical  investment on the last day of the designated  period in accordance
with the following formula:
    

                            P(1+T)n  =  ERV

   
Where:      P    =     a hypothetical initial payment of $1000, less the 
                       maximum sales load of $5.75 for Class A shares or
                       the deduction of any CDSC applicable to Class B or C
                       shares as of the end of the period.
    

            T    =     average annual total return

            n    =     number of years

                                      B-32
<PAGE>

            ERV  =     ending redeemable value of the hypothetical $1000
                       initial payment made at the beginning of the
                       designated period (or fractional portion thereof)

         For  purposes  of  the  above  computation,   that  all  dividends  and
distributions  made by the Fund are  reinvested  at net asset  value  during the
designated  period.  The average annual total return  quotation is determined to
the nearest 1/100 of 1%.

         In determining the average annual total return  (calculated as provided
above), recurring fees, if any, that are charged to all shareholder accounts are
taken into  consideration.  For any account  fees that vary with the size of the
account,  the account fee used for purposes of the above  computation is assumed
to be the fee that would be charged to the Fund's mean account size.

   
         The average  annual total return for the Class A shares of the Fund for
the periods October 25, 1993 to June 30, 1994, July 1, 1994 to December 31, 1994
and  January  1,  1995  to  June  30,  1995  were  -1.47%,  -2.16%  and  -2.11%,
respectively.  The Fund's one-year and  life-of-Fund  annual total returns as of
June 30, 1995 were -4.23% and -3.40%,  respectively.  Assuming no fee reductions
or expense  limitations,  the Fund's  annual  total  return for the same periods
would have been lower.  No Class B or Class C shares were  outstanding  prior to
January, 1996.
    

         Other Quotations,  Comparisons,  and General Information.  From time to
time, in advertisements, in sales literature, or in reports to shareholders, the
past  performance  of the Fund may be illustrated  and/or  compared with that of
other  mutual funds with similar  investment  objectives,  and to stock or other
relevant  indices.  For  example,  the Fund's  total  return may be  compared to
averages or rankings  prepared by Lipper  Analytical  Services,  Inc.,  a widely
recognized  independent  service which  monitors  mutual fund  performance;  the

                                   APPENDIX A

                           DESCRIPTION OF BOND RATINGS


         The rating systems  described herein are believed to be the most recent
ratings systems  available from Moody's Investors  Service,  Inc. and Standard &
Poor's Ratings Group at the date of this Statement of Additional Information for
the securities listed.  Ratings are generally given to securities at the time of
issuance.  While the rating  agencies may from time to time revise such ratings,
they  undertake  no  obligation  to do so,  and  the  ratings  indicated  do not
necessarily  represent  ratings  which will be given to these  securities on the
date of the Fund's fiscal year end.

Moody's Investors Service, Inc.

         Aaa:  Bonds  which are rated Aaa are judged to be of the best  quality.
They carry the smallest degree of investment risk and are generally  referred to
as  "gilt  edge."  Interest   payments  are  protected  by  a  large  or  by  an
exceptionally   stable  margin  and  principal  is  secure.  While  the  various
protective  elements are likely to change, such changes as can be visualized are
most unlikely to impair the fundamentally strong position of such issues.

         Aa:  Bonds  which are rated Aa are judged to be of high  quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.

         A: Bonds which are rated A possess many favorable investment attributes
and are to be  considered  as upper medium  grade  obligations.  Factors  giving
security to principal and interest are considered adequate,  but elements may be
present which suggest a susceptibility to impairment sometime in the future.

         Baa:  Bonds  which  are  rated  Baa  are  considered  as  medium  grade
obligations,  i.e.,  they are  neither  highly  protected  nor  poorly  secured.
Interest  payments and principal  security  appear  adequate for the present but
certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

         Ba: Bonds which are rated Ba are judged to have  speculative  elements;
their future  cannot be  considered  as well  assured.  Often the  protection of
interest  and  principal  payments  may be very  moderate  and  thereby not well
safeguarded  during  both good and bad times  over the  future.  Uncertainty  of
position characterizes bonds in this class.

         B:  Bonds  which  are rated B  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

                                      B-35
<PAGE>

         Caa: Bonds which are rated Caa are of poor standing. Such issues may be
in default or there may be present  elements of danger with respect to principal
or interest.

         Ca:  Bonds  which  are  rated  Ca  represent   obligations   which  are
speculative  in a high  degree.  Such  issues are often in default or have other
marked shortcomings.

         C: Bonds  which are rated C are the lowest  rated  class of bonds,  and
issues so rated can be  regarded  as having  extremely  poor  prospects  of ever
attaining any real investment standing.

         Unrated:  Where no rating has been  assigned or where a rating has been
suspended or  withdrawn,  it may be for reasons  unrelated to the quality of the
issue.

         Should no rating be assigned, the reason may be one of the following:

         1.       An application for rating was not received or accepted.

         2.       The issue or issuer belongs to a group of securities or 
                  companies that are not rated as a matter of policy.

         3.       There is a lack of essential data pertaining to the issue 
                  or issuer.

         4.       The issue was privately placed, in which case the rating is 
                  not published in Moody's publications.

         Suspension  or withdrawal  may occur if new and material  circumstances
arise,  the  effects of which  preclude  satisfactory  analysis;  if there is no
longer available  reasonable  up-to-date data to permit a judgment to be formed;
if a bond is called for redemption; or for other reasons.

         Note:  Those  bonds in the Aa, A, Baa,  Ba and B groups  which  Moody's
believe  possess the  strongest  investment  attributes  are  designated  by the
symbols Aa1, A1, Baa1 and B1.

Standard & Poor's Ratings Group1

         AAA:  Bonds  rated AAA have the highest  rating  assigned by Standard &
Poor's. Capacity to pay interest and repay principal is extremely strong.

         AA:  Bonds rated AA have a very strong  capacity  to pay  interest  and
repay principal and differ from the higher rated issues only in small degree.


- --------
         Rates  all  governmental  bodies  having  $1,000,000  or  more  of debt
outstanding, unless adequate information is not available.

                                      B-36
<PAGE>

         A: Bonds rated A have a very strong  capacity to pay interest and repay
principal  although they are somewhat more susceptible to the adverse effects of
changes in  circumstances  and  economic  conditions  than bonds in higher rated
categories.

         BBB: Bonds rated BBB are regarded as having an adequate capacity to pay
interest and repay principal.  Whereas they normally exhibit adequate protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
bonds in this category than in higher rated categories.

         BB, B, CCC,  CC, C: Bonds rated BB, B, CCC, CC and C are  regarded,  on
balance,  as predominantly  speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. BB indicates
the lowest degree of speculation  and the highest degree of  speculation.  While
such bonds will likely have some quality and protective  characteristics,  these
are  outweighed  by large  uncertainties  of major  risk  exposures  to  adverse
conditions.

         D: Bonds rated D are in payment default.  The D rating category is used
when interest  payments or principal  payments are not made on the date due even
if the  applicable  grace  period  has not  expired,  unless  Standard  & Poor's
believes that such payments will be made during such grace period.

         Plus (+) or Minus (-):  The ratings from "AA" to "B" may be modified by
the addition of a plus or minus sign to show relative  standing within the major
rating categories.

         Unrated: Indicates that no public rating has been requested, that there
is insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular type of obligations as a matter of policy.

                               INDEX DESCRIPTIONS

S&P 500 *
This index is a readily available, carefully constructed,  market value weighted
benchmark  of common  stock  performance.  Currently,  the S&P  Composite  Index
includes  500 of the  largest  stocks  (in terms of stock  market  value) in the
United States; prior to March 1957 it consisted of 90 of the largest stocks.

DOW JONES INDUSTRIAL AVERAGE *
This is a total return index based on the performance of 30 blue chip stocks.

SMALL CAPITALIZATION STOCKS *
This index is a market value  weighted  index of the ninth and tenth  deciles of
the New York Stock  Exchange  (NYSE),  plus stocks listed on the American  Stock
Exchange (AMEX) and over-the-counter  (OTC) with the same or less capitalization
as the upper bound of the NYSE ninth decile.

INFLATION *
The  Consumer  Price  Index  for All Urban  Consumers  (CPI-U),  not  seasonally
adjusted, is used to measure inflation,  which is the rate of change of consumer
goods prices.  Unfortunately,  the  inflation  rate as derived by the CPI is not
measured  over the same period as the other asset  returns.  All of the security
returns are measured  from one  month-end to the next  month-end.  CPI commodity
prices are collected during the month.  Thus,  measured  inflation rates lag the
other  series  by about  one-half  month.  Prior to  January  1978,  the CPI (as
compared with CPI-U) was used.  Both inflation  measures are  constructed by the
U.S. Department of Labor, Bureau of Labor Statistics, Washington, DC.

S&P/BARRA INDEXES *
"The S&P/BARRA  Growth and Value Indexes are  constructed by dividing the stocks
in the S&P 500  Index  according  to  price-to-book  ratios.  The  Growth  Index
contains stocks with higher  price-to-book  ratios, and the Value Index contains
stocks with lower price-to-book  ratios. Both indexes are market  capitalization
weighted."

LONG-TERM MUNICIPAL BOND PORTFOLIO *
For 1926-1984,  returns are calculated  form yields on 20-year prime issues from
Solomon  Brothers'  Analytical  Record of Yields  and Yields  Spreads,  assuming
coupon equals previous year-end yield and a 20-year maturity.  For 1985-present,
returns are  calculated  using Moody's Bond Record,  using the December  average
municipal yield as the  beginning-of-following  year coupon (average of Aaa, Aa,
A, Baa grades).

LONG-TERM CORPORATE BONDS *
For  1969-1991,  corporate  bond total  returns are  represented  by the Salomon
Brothers Long-Term  High-Grade  Corporate Bond Index. Since most large corporate
bond  transactions  take place over the  counter,  a major dealer is the natural
source of these data. The index includes  nearly all Aaa- and Aa-rated bonds. If


                                      B-39
<PAGE>

a bond is  downgraded  during a  particular  month,  its return for the month is
included in the index before removing the bond from future portfolios.

Over  1926-1968  the total  returns  were  calculated  by  summing  the  capital
appreciation returns and the income returns. For the period 1946-1968,  Ibbotson
and Sinquefield  backdated the Salomon Brothers' index,  using Salomon Brothers'
monthly  yield  data with a  methodology  similar  to that used by  Salomon  for
1969-1991. Capital appreciation returns were calculated from yields assuming (at
the beginning of each monthly holding period) a 20-year  maturity,  a bond price
equal to par,  and a  coupon  equal to the  beginning-of-period  yield.  For the
period 1926-1945, the Standard and Poor's monthly High-Grade Corporate Composite
yield data were used,  assuming a 4 percent coupon and a 20-year  maturity.  The
conventional  present-value  formula  for  bond  price  for  the  beginning  and
end-of-month  prices was used.  (This formula is presented in Ross,  Stephen A.,
and Randolph W. Westerfield,  Corporate Finance, Times Mirror/Mosby,  St. Louis,
1990, p. 97 ["Level-Coupon Bonds"].) The monthly income return was assumed to be
one-twelfth the coupon.

LONG-TERM GOVERNMENT BOND TOTAL RETURN *
The  total  returns  on  long-term  government  bonds  from  1977  to  1991  are
constructed  with data from The Wall Street Journal.  Over  1926-1976,  data are
obtained  from the  Government  bond file at the Center for Research in Security
Prices (CRSP), Graduate School of Business,  University of Chicago. Each year, a
one-bond  portfolio  with a term of  approximately  20  years  and a  reasonably
current  coupon  was used,  and whose  returns  did not  reflect  potential  tax
benefits,  impaired  negotiability,  or special  redemption or call  privileges.
Where  callable  bonds had to be used,  the term of the bond was assumed to be a
simple  average of the maturity and first call dates minus the current date. The
bond was "held" for the calendar year and returns were  computed.  Total returns
for  1977-1991 are  calculated  as the change in the flat price or  and-interest
price.

INTERMEDIATE-TERM GOVERNMENT BONDS TOTAL RETURN *
Total  returns  of the  intermediate-term  government  bonds for  1977-1991  are
calculated from The Wall Street Journal prices,  using the change in flat price.
Returns from 1934-1986 are obtained from the CRSP Government Bond File.

Each year,  one-bond  portfolios  are formed,  the bond  chosen is the  shortest
noncallable  bond with a maturity not less than 5 years, and this bond is "held"
for the  calendar  year.  Monthly  returns are  computed.  (Bonds with  impaired
negotiability or special redemption  privileges are omitted, as are partially or
fully  tax-exempt  bonds starting with 1943.) From  1934-1942,  almost all bonds
with maturities near 5 years were partially or full tax-exempt and were selected
using the rules described  above.  Personal tax rates were generally low in that
period,  so that yields on  tax-exempt  bonds were  similar to yields on taxable
bonds. From 1926-1933, there are few bonds suitable for construction of a series
with a 5-year  maturity.  For this period,  five year bond yield  estimates  are
used.

U.S. (30 DAY) TREASURY BILL TOTAL RETURNS *
For the U.S. Treasury bill index, data from The Wall Street Journal are used for
1977-1991;  the CRSP U.S.  Government  Bond File is the source until 1976.  Each
month a one-bill  portfolio  containing the  shortest-term  bill having not less
than one month to maturity is constructed. (The bill's original term to maturity
is not relevant.) To measure holding period returns for the one-bill  portfolio,
the bill is priced as of the last trading day of the previous  month-end  and as
of the last trading day of the current month.

Item 27. Indemnification.

                  Except for the Agreement and  Declaration of Trust dated March
10, 1995  establishing the Registrant as a Trust under Delaware law, there is no
contract,  arrangement or statute under which any director, officer, underwriter
or affiliated person of the Registrant is insured or indemnified.  The Agreement
and Declaration of Trust provides that no Trustee or officer will be indemnified
against any  liability  to which the  Registrant  would  otherwise be subject by
reason of or for willful  misfeasance,  bad faith,  gross negligence or reckless
disregard of such person's duties.

                  Insofar as  indemnification  for  liability  arising under the
Securities  Act of 1933, as amended (the "Act"),  may be available to directors,
officers and  controlling  persons of the  Registrant  pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Act and is,  therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment of the Registrant of expenses incurred or paid by a director, officer or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

Item 28. Business and Other Connections of Investment Adviser.

                  The  business  and  other  connections  of  the  officers  and
directors  of  the  Registrant's   investment  adviser,   Pioneering  Management
Corporation,  are listed on the Form ADV of Pioneering Management Corporation as
currently on file with the Commission (File No. 801-8255),  the text of which is

                               MANAGEMENT CONTRACT


THIS  AGREEMENT  dated this 26th day of  September,  1995  between  Pioneer Real
Estate  Shares,  a  Delaware  business  trust  (the  "Trust"),   and  Pioneering
Management Corporation, a Delaware corporation (the "Manager").

                               W I T N E S S E T H

WHEREAS,  the  Trust  is  registered  as an  open-end,  diversified,  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 (the  "Registration  Statement") for the
purpose of registering  its shares for public  offering under the Securities Act
of 1933, as amended,

WHEREAS,  the Trust  currently  issues a single  series  of shares  representing
interests in one portfolio (the "Portfolio"),

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 Portfolio,

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

     1. (a) The Manager will  regularly  provide the Portfolio  with  investment
research,  advice and  supervision  and will furnish  continuously an investment
program for the Portfolio consistent with the investment objectives and policies
of the Portfolio.  The Manager will determine from time to time what  securities
shall be purchased for the Portfolio,  what securities  shall be held or sold by
the  Portfolio  and  what  portion  of the  Portfolio's  assets  shall  be  held
uninvested as cash, subject always to the provisions of the Trust's  Declaration
of Trust,  By-Laws and its registration  statements under the 1940 Act and under
the  Securities  Act of 1933  covering  the  Trust's  shares,  as filed with the
Securities and Exchange Commission,  and to the investment objectives,  policies
and  restrictions  of the  Portfolio,  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
Portfolio  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

<PAGE>

furtherance or conduct of such purchases, sales or other transactions.

     (b) The Manager will, to the extent  reasonably  required in the conduct of
the  business  of the  Portfolio  and upon the Trust's  request,  furnish to the
Portfolio  research,  statistical  and  advisory  reports  upon the  industries,
businesses,  corporations or securities as to which such requests shall be made,
whether  or not the  Portfolio  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 entities.

     (c) The Manager  will  maintain  all books and records  with respect to the
Portfolio's securities  transactions required by sub-paragraphs (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 with respect to the  Portfolio)  and preserve such records for the periods
prescribed therefor by Rule 31a-2 of the 1940 Act. The Manager will also provide
to the Board of Trustees  such  periodic  and  special  reports as the Board may
reasonably request.

     2.The  Manager  recognizes  that the  Trust  may from  time to time  create
additional  portfolios  of the Trust,  that this  agreement  relates only to the
management of the assets of the single existing Portfolio of the Trust, and that
the  management of the assets of any  additional  portfolio of the Trust will be
subject to one or more separate investment management agreements.

     3. (a)  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 affairs
and investments with respect to the Portfolio,  and shall arrange, if desired by
the Trust,  for members of the  Manager's  organization  to serve as officers or
agents of the Trust.

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

                                       2
<PAGE>

     (c) 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
and registrar  appointed by the Trust with respect to the Portfolio;  (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 the Commission,  state or blue
sky  securities  agencies and foreign  countries,  including the  preparation of
Prospectuses  and  Statements  of  Additional  Information  for filing  with the
Commission;  (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) distribution 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),  The Pioneer Group, Inc. or Pioneer Funds Distributor,  Inc.;
(xi) the cost of preparing and printing  share  certificates;  (xii) interest on
borrowed  money,  if any;  and  (xii)  organizational  expenses  of the Trust or
Portfolio.

     (d) In addition to the expenses  described in Section 3(c) above, the Trust
shall pay all brokers' and underwriting  commissions chargeable to the Portfolio
in connection with securities transactions to which the Portfolio is a party.

     4.It is understood  that the Manager may employ one or more  sub-investment
advisers  (each  a  "Subadviser")   under  written  agreements  with  each  such
Subadviser,  provided that any such agreement is first approved by the vote of a
majority  of the  Trustees,  including a majority  of the  Trustees  who are not
"interested  persons"  (as the term  "interested  person" is defined in the 1940
Act) of the Trust, the Manager or any such Subadviser,  at a meeting of Trustees
called for the purpose of voting on such  approval  and by a vote of a "majority
of the  outstanding  voting  securities"  (as  defined  in the 1940  Act) of the
Portfolio. The authorization given to the Manager in Sections 1 and 7 hereof may
be delegated by it under any such agreement to any of the Subadvisers,  provided
that the Subadvisers  shall be subject to the same  restrictions and limitations
on the  investments and brokerage  discretion as the Manager.  While the Manager


                                       3
<PAGE>

shall be responsible for allocating  assets among the Subadvisers and monitoring
their  relative  performances,  the Trust agrees that the Manager  should not be
accountable to the Trust or the Portfolio or the  Portfolio's  shareholders  for
any loss or other  liability  relating to specific  investments  directed by any
Subadviser  (even  though the  Manager  retains  the right to  reserve  any such
investment),   because  the  Trust  and  the  Manager  will  be  relying  almost
exclusively on the expertise of the Subadvisers for the selection and monitoring
of specific investments directed by the Subadvisers.

     5.  (a)  The  Trust  shall  pay to the  Manager,  as  compensation  for the
Manager's  services  hereunder,  a fee at the  rate of  1.00%  per  annum of the
Portfolio's average daily net assets. The management fee payable hereunder shall
be computed  daily and paid monthly in arrears.  In the event of  termination of
this Agreement,  the fee provided in this Section 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.

     (b) If the  operating  expenses  of the  Portfolio  in any year  exceed the
limits set by state  securities laws or regulations in states in which shares of
the Portfolio are sold, the amount  payable to the Manager under  subsection (a)
above  will be  reduced  (but not below $0),  and the  Manager  shall make other
arrangements  concerning  expenses  but,  in each  instance,  only as and to the
extent  required  by such laws or  regulation.  If  amounts  have  already  been
advanced  to the Manager  under this  Agreement,  the  Manager  will return such
amounts to the Trust to the extent required by the preceding sentence.

     (c) In addition to the  foregoing,  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.

     6.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 Portfolio or its
shareholders by reason of willful misfeasance,  bad faith or gross negligence in


                                       4
<PAGE>

the  performance  of its duties or by reason of its  reckless  disregard  of its
obligations and duties under this Agreement.

     7. (a)  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  advisor  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  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.

     (b) In connection  with purchases or sales of portfolio  securities for the
account of the Portfolio, 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 portfolio  securities  for the  Portfolio'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  Portfolio  the most  favorable  execution  and net
price  available  except as described  herein.  It is also understood that it is
desirable  for the  Portfolio  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 Portfolio
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
Portfolio 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.

     (c) On occasions  when the Manager deems the purchase or sale of a security
to be in the  best  interest  of the  Portfolio  as well as other  clients,  the
Manager,  to the  extent  permitted  by  applicable  laws and  regulations,  may
aggregate  the  securities  to be sold or  purchased in order to obtain the best


                                       5
<PAGE>

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 Portfolio
and to such clients.

     8.This Agreement shall become effective on the date hereof and shall remain
in force until May 31, 1997 and from year to year  thereafter,  but only so long
as its  continuance is approved  annually 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 the term  "interested  persons" is
defined in the 1940 Act) of any such  parties,  at a meeting of Trustees  called
for the purpose of voting on such  approval  or by a vote of a "majority  of the
outstanding  voting  securities"  (as defined in the 1940 Act) of the Portfolio,
subject to the right of the Trust and the Manager to terminate  this contract as
provided in Section 9 hereof.

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

     10.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.

     11. 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, and any series thereof,  will be changed to one that does not contain the
name "Pioneer" or otherwise suggest an affiliation with the Manager.

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

     13.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.

                                       6
<PAGE>

     14.This  Agreement and all  performance  hereunder shall be governed by the
laws of The Commonwealth of Massachusetts,  which apply to contracts made and to
be performed in The Commonwealth of Massachusetts.

     15.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.

     16.The parties to this Agreement acknowledge and agree that all liabilities
arising  hereunder,  whether  direct or  indirect,  and of any and every  nature
whatsoever shall be satisfied solely out of the assets of the portfolio affected
thereby and that no Trustee,  officer or holder of shares of beneficial interest
of the Trust shall be personally  liable for any of the  foregoing  liabilities.
The Trust's  Certificate  of Trust,  as amended from time to time, is on file in
the Office of the Secretary of State of the State of Delaware.  Such Certificate
of Trust and the Trust's  Declaration of Trust describe in detail the respective
responsibilities  and  limitations on liability of the Trustees,  officers,  and
holders of shares of beneficial interest.

     17.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.

                    FORM OF CLASS B SHARES DISTRIBUTION PLAN

                           PIONEER REAL ESTATE SHARES


CLASS B SHARES  DISTRIBUTION  PLAN, dated as of January __, 1996 of PIONEER REAL
ESTATE SHARES, a Delaware business trust (the "Trust").

                                   WITNESSETH

WHEREAS,  the Trust is  engaged in  business  as an  open-end,  non-diversified,
management investment company and is registered under the Investment Company Act
of 1940, as amended  (collectively  with the rules and  regulations  promulgated
thereunder, the "1940 Act");

WHEREAS,  the Trust  intends to distribute  shares of  beneficial  interest (the
"Class B Shares") of the Trust in accordance with Rule 12b-1  promulgated by the
Securities  and  Exchange  Commission  under the 1940 Act  ("Rule  12b-1"),  and
desires to adopt this Class B Shares distribution plan (the "Class B Plan") as a
plan of distribution pursuant to such Rule;

WHEREAS, the Trust desires that Pioneer Funds Distributor, Inc., a Massachusetts
corporation ("PFD"), provide certain distribution services for the Trust's Class
B Shares in connection with the Class B Plan;

WHEREAS,  the  Trust  has  entered  into an  underwriting  agreement  (in a form
approved by the Trust's  Board of  Trustees in a manner  specified  in such Rule
12b-1) with PFD,  whereby PFD  provides  facilities  and  personnel  and renders
services to the Trust in connection with the offering and  distribution of Class
B Shares (the "Underwriting Agreement");

WHEREAS,  the Trust  also  recognizes  and  agrees  that (a) PFD may  retain the
services of firms or individuals to act as dealers or wholesalers (collectively,
the "Dealers") of the Class B Shares in connection  with the offering of Class B
Shares,  (b) PFD may  compensate  any Dealer  that  sells  Class B Shares in the
manner and at the rate or rates to be set forth in an agreement  between PFD and
such Dealer and (c) PFD may make such  payments to the Dealers for  distribution
services  out of the fee  paid to PFD  hereunder,  any  deferred  sales  charges
imposed by PFD in connection with the repurchase of Class B Shares,  its profits
or any other source available to it;

WHEREAS,  the Trust  recognizes and agrees that PFD may impose certain  deferred
sales charges in connection  with the repurchase of Class B Shares by the Trust,
and PFD may retain  (or  receive  from the  Trust,  as the case may be) all such
deferred sales charges; and

WHEREAS,  the Board of Trustees of the Trust,  in considering  whether the Trust
should adopt and implement this Class B Plan, has evaluated such  information as
it deemed  necessary  to an  informed  determination  whether  this Class B Plan
should be adopted and implemented  and has considered such pertinent  factors as
it deemed  necessary to form the basis for a decision to use assets of the Trust
for such purposes, and has determined that there is a reasonable likelihood that
the adoption and  implementation of this Class B Plan will benefit the Trust and
its Class B shareholders;

NOW,  THEREFORE,  the Board of Trustees of the Trust hereby  adopts this Class B
Plan for the Trust as a plan of  distribution  of Class B Shares  in  accordance
with Rule 12b-1, on the following terms and conditions:

     1. (a) The  Trust is  authorized  to  compensate  PFD for (1)  distribution
services  and (2)  personal  and  account  maintenance  services  performed  and
expenses  incurred by PFD in connection  with the Trust's  Class B Shares.  Such
compensation  shall be calculated  and accrued daily and paid monthly or at such
other intervals as the Board of Trustees may determine.

        (b)The amount of compensation  paid during any one year for distribution
services  with  respect to Class B Shares  shall be .75% of the Trust's  average
daily net assets attributable to Class B Shares for such year.

        (c)Distribution  services and expenses for which PFD may be  compensated
pursuant to this Plan include, without limitation:  compensation to and expenses
(including  allocable  overhead,  travel and telephone expenses) of (i) Dealers,
brokers  and other  dealers  who are  members  of the  National  Association  of
Securities Dealers,  Inc. ("NASD") or their officers,  sales representatives and
employees,  (ii)  PFD and any of its  affiliates  and  any of  their  respective
officers,  sales representatives and employees,  (iii) banks and their officers,
sales  representatives and employees,  who engage in or support  distribution of
the Trust's Class B Shares;  printing of reports and prospectuses for other than
existing  shareholders;  and  preparation,  printing and  distribution  of sales
literature and advertising materials.

        (d)The amount of compensation paid for personal and account  maintenance
services  and  expenses  shall be .25% of the Trust's  average  daily net assets
attributable  to Class B Shares for such  year.  As  partial  consideration  for
personal  services and/or account  maintenance  services  provided by PFD to the
Class B Shares,  PFD shall be  entitled to be paid any fees  payable  under this
clause (d) with respect to Class B Shares for which no dealer of record  exists,
where less than all  consideration  has been paid to a dealer of record or where
qualification standards have not been met.

        (e)Personal and account maintenance services for which PFD or any of its
affiliates,  banks or Dealers may be compensated  pursuant to this Plan include,
without  limitation:  payments  made  to or on  account  of  PFD  or  any of its
affiliates,  banks,  other  brokers and dealers who are members of the NASD,  or
their officers,  sales  representatives and employees,  who respond to inquiries
of, and furnish assistance to, shareholders regarding their ownership of Class B
Shares or their accounts or who provide similar services not otherwise  provided
by or on behalf of the Trust.

        (f)PFD may impose certain  deferred sales charges in connection with the
repurchase  of Class B Shares by the Trust and PFD may retain (or  receive  from
the Trust as the case may be) all such deferred sales charges.

        (g)Appropriate  adjustments to payments made pursuant to clauses (b) and
(d) of this  paragraph  1 shall be made  whenever  necessary  to ensure  that no
payment is made by the Trust in excess of the applicable  maximum cap imposed on
asset based,  front-end and deferred  sales charges by subsection (d) of Section
26 of Article III of the Rules of Fair Practice of the NASD.

     2.The Trust understands that agreements between PFD and Dealers may provide
for payment of fees to Dealers in connection with the sale of Class B Shares and
the provision of services to shareholders of the Trust.  Nothing in this Class B
Plan shall be construed as requiring the Trust to make any payment to any Dealer
or to have any obligations to any Dealer in connection with services as a dealer
of the Class B Shares.  PFD shall agree and undertake that any agreement entered
into between PFD and any Dealer shall provide that such Dealer shall look solely
to PFD for compensation  for its services  thereunder and that in no event shall
such Dealer seek any payment from the Trust.

     3.Nothing herein contained shall be deemed to require the Trust to take any
action  contrary to its  Declaration of Trust,  as it may be amended or restated
from  time to  time,  or  By-Laws  or any  applicable  statutory  or  regulatory
requirement  to which it is  subject  or by which it is bound,  or to relieve or
deprive the Trust's Board of Trustees of the  responsibility  for and control of
the conduct of the affairs of the Trust.

     4.This Class B Plan shall become effective upon approval by (i) a "majority
of the outstanding  voting  securities" of Class B of the Trust,  (ii) a vote of
the Board of  Trustees,  and (iii) a vote of a majority of the  Trustees who are
not  "interested  persons"  of the  Trust  and who have no  direct  or  indirect
financial  interest in the  operation  of the Class B Plan or in any  agreements
related to the Class B Plan (the "Qualified Trustees"),  such votes with respect
to (ii) and (iii) above to be cast in person at a meeting called for the purpose
of voting on this Class B Plan.

     5.This Class B Plan will remain in effect indefinitely,  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained, this Class B Plan shall expire on April
30 of such year.

     6.This  Class B Plan may be amended  at any time by the Board of  Trustees,
provided  that this Class B Plan may not be amended to increase  materially  the
limitations on the annual percentage of average net assets which may be expended
hereunder  without the  approval of holders of a  "majority  of the  outstanding
voting  securities" of Class B of the Trust and may not be materially amended in
any case  without a vote of a majority of both the  Trustees  and the  Qualified
Trustees.  This  Class  B Plan  may be  terminated  at any  time  by a vote of a
majority of the Qualified Trustees or by a vote of the holders of a "majority of
the outstanding voting securities" of Class B of the Trust.

     7.The Trust and PFD shall provide to the Trust's Board of Trustees, and the
Board of Trustees  shall review,  at least  quarterly,  a written  report of the
amounts  expended  under  this  Class B Plan and the  purposes  for  which  such
expenditures were made.

     8.While this Class B Plan is in effect,  the  selection  and  nomination of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

     9.For  the  purposes  of  this  Class  B  Plan,  the  terms   "assignment,"
"interested  persons,"  "majority  of the  outstanding  voting  securities"  and
"specifically approved at least annually" are used as defined in the 1940 Act.

     10.The Trust shall preserve copies of this Class B Plan, and each agreement
related hereto and each report referred to in Paragraph 7 hereof  (collectively,
the "Records"),  for a period of not less than six (6) years from the end of the
fiscal year in which such  Records  were made and for a period of two (2) years,
each of such Records shall be kept in an easily accessible place.

     11.This Class B Plan shall be construed in accordance  with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

     12.If any provision of this Class B Plan shall be held or made invalid by a
court decision,  statute,  rule or otherwise,  the remainder of the Class B Plan
shall not be affected thereby.

                           PIONEER REAL ESTATE SHARES

                   Multiple Class Plan Pursuant to Rule 18f-3

                Class A Shares, Class B Shares and Class C Shares

                                 October 4, 1995


     Each class of shares of Pioneer  Real Estate  Shares,  a Delaware  business
trust (the "Fund"),  will have the same relative  rights and  privileges  and be
subject to the same sales charges, fees and expenses, except as set forth below.
The Board of  Trustees  may  determine  in the future  that  other  distribution
arrangements,  allocations of expenses  (whether  ordinary or  extraordinary) or
services to be provided to a class of shares are appropriate and amend this Plan
accordingly  without the approval of  shareholders  of any class.  Except as set
forth in the Fund's  prospectus,  shares may be exchanged only for shares of the
same class of another Pioneer mutual fund.

                            Article I. Class A Shares

     Class A Shares are sold at net asset value and subject to the initial sales
charge  schedule  or  contingent  deferred  sales  charge  ("CDSC")  and minimum
purchase  requirements  as set forth in the  Fund's  prospectus.  Class A Shares
shall be entitled to the shareholder services set forth from time to time in the
Fund's prospectus with respect to Class A Shares.  Class A Shares are subject to
fees calculated as a stated percentage of the net assets attributable to Class A
shares  under the Fund's  Class A Rule 12b-1  Distribution  Plan as set forth in
such  Distribution  Plan. The Class A Shareholders have exclusive voting rights,
if any,  with  respect to the Class A Rule  12b-1  Distribution  Plan.  Transfer
agency fees are allocated to Class A Shares on a per account basis except to the
extent,  if any, such an allocation  would cause the Fund to fail to satisfy any
requirement  necessary  to obtain or rely on a private  letter  ruling  from the
Internal Revenue Service ("IRS") relating to the issuance of multiple classes of
shares.  Class A shares  shall  bear the  costs  and  expenses  associated  with
conducting a shareholder meeting for matters relating to Class A shares.

                           Article II. Class B Shares

     Class B Shares are sold at net asset value per share without the imposition
of an initial sales charge.  However, Class B shares redeemed within a specified
number of years of purchase will be subject to a CDSC as set forth in the Fund's
prospectus. Class B Shares are sold subject to the minimum purchase requirements
set forth in the Fund's  prospectus.  Class B Shares  shall be  entitled  to the
shareholder  services set forth from time to time in the Fund's  prospectus with
respect to Class B Shares.  Class B Shares are subject to fees  calculated  as a
stated  percentage  of the net assets  attributable  to Class B shares under the
Class B Rule 12b-1 Distribution Plan as set forth in such Distribution Plan. The
Class B  Shareholders  of the Fund have exclusive  voting  rights,  if any, with
respect to the Fund's Class B Rule 12b-1 Distribution Plan. Transfer agency fees
are allocated to Class B Shares on a per account basis except to the extent,  if
any, such an allocation  would cause the Fund to fail to satisfy any requirement
necessary to obtain or rely on a private  letter ruling from the IRS relating to
the issuance of multiple classes of shares.  Class B shares shall bear the costs
and  expenses  associated  with  conducting  a  shareholder  meeting for matters
relating to Class B shares.

     Class B Shares will automatically  convert to Class A Shares of the Fund at
the end of a specified  number of years after the initial purchase date of Class
B shares,  except as provided in the Fund's  prospectus.  Such  conversion  will
occur at the  relative  net  asset  value per share of each  class  without  the
imposition of any sales charge,  fee or other charge.  The conversion of Class B
Shares  to  Class  A  Shares  may be  suspended  if it is  determined  that  the
conversion  constitutes or is likely to constitute a taxable event under federal
income tax law.

     The  initial  purchase  date  for  Class  B  shares  acquired  through  (i)
reinvestment  of  dividends  on Class B Shares  or (ii)  exchange  from  another
Pioneer  mutual fund will be deemed to be the date on which the original Class B
shares were purchased.

                           Article III. Class C Shares

     Class C Shares are sold at net asset value per share without the imposition
of an initial sales charge.  However, Class C shares redeemed within one year of
purchase will be subject to a CDSC as set forth in the Fund's prospectus.  Class
C Shares are sold subject to the minimum purchase  requirements set forth in the
Fund's prospectus.  Class C Shares shall be entitled to the shareholder services
set forth from time to time in the  Fund's  prospectus  with  respect to Class C
Shares.  Class C Shares are subject to fees calculated as a stated percentage of
the net  assets  attributable  to Class C shares  under the  Class C Rule  12b-1
Distribution  Plan  as  set  forth  in  such  Distribution  Plan.  The  Class  C
Shareholders of the Fund have exclusive  voting rights,  if any, with respect to
the Fund's  Class C Rule  12b-1  Distribution  Plan.  Transfer  agency  fees are
allocated to Class C Shares on a per account basis except to the extent, if any,
such an  allocation  would  cause the Fund to fail to  satisfy  any  requirement
necessary to obtain or rely on a private  letter ruling from the IRS relating to
the issuance of multiple classes of shares.  Class C shares shall bear the costs
and  expenses  associated  with  conducting  a  shareholder  meeting for matters
relating to Class C shares.

     The  initial  purchase  date  for  Class  C  shares  acquired  through  (i)
reinvestment  of  dividends  on Class C Shares  or (ii)  exchange  from  another
Pioneer  mutual fund will be deemed to be the date on which the original Class C
shares were purchased.

                    Article IV. Approval by Board of Trustees

     This Plan shall not take effect until it has been approved by the vote of a
majority (or whatever  greater  percentage  may,  from time to time, be required
under Rule 18f-3  under the  Investment  Company  Act of 1940,  as amended  (the
"Act")) of (a) all of the  Trustees of the Fund,  and (b) those of the  Trustees
who are not  "interested  persons" of the Fund, as such term may be from time to
time defined under the Act.

                              Article V. Amendments

     No material  amendment to the Plan shall be effective unless it is approved
by the Board of Trustees in the same manner as is provided  for approval of this
Plan in Article IV.
