REAL ESTATE SHARES


CLASS Y SHARES PROSPECTUS
March 26, 1998

        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.

  II. FINANCIAL HIGHLIGHTS

       Class Y shares are a new class of shares;  financial  highlights  are not
currently  available  for Class Y shares.  Arthur  Andersen  LLP's report on the
Fund's audited financial statements as of December 31, 1996 for Class A, Class B
and Class C shares appears in the Fund's Annual Report which is  incorporated by
reference  into the  Statement  of  Additional  Information.  The Annual  Report
includes more information about the Fund's  performance and is available free of
charge by calling Shareholder Services at 1-888-294-4480.

  III. INVESTMENT OBJECTIVES AND POLICIES AND ASSOCIATED RISKS

       The Fund's primary  investment  objective is to seek long-term  growth of
capital.  Current  income is a secondary  investment  objective.  The Fund seeks
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 REITs 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 securities 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 Pioneering Management  Corporation
("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.

       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"),  commonly  referred to as
junk bonds, 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 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 has  qualified,  and intends to  continue  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. The Board meets at least  quarterly.  By
virtue  of the  functions  performed  by 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 MANAGER

       The Fund is managed  under a management  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 and PFD,  and  President  and a Director of PGI,
beneficially owned  approximately 14% of the outstanding capital stock of PGI as
of the date of this Prospectus.

       Mr. David  Tripple,  President  and Chief  Investment  Officer of PMC and
Executive Vice President of each Pioneer mutual fund, has general responsibility
for PMC's investment  operations and chairs a committee of PMC's equity managers
which reviews PMC's research and portfolio  operations,  including  those of the
Fund. Mr. Tripple joined PMC in 1974.

       Research  and  management  of the  Fund is the  responsibility  of a team
consisting  of a PMC  portfolio  manager  and  analysts  from  Boston  Financial
Securities,  Inc.  ("BFS"),  the  Fund's  subadviser.  Members  of the team meet
regularly  to  discuss   holdings,   prospective   investments   and   portfolio
composition.  Mr. Robert  Bensen,  a Vice  President of PMC and the Fund, is the
senior  member of the team.  Mr.  Bensen  joined PMC in 1974 and has 23 years of
investment  experience.  Mr. Bensen is responsible for the day-to-day management
of the Fund.

       In addition to the Fund,  PMC also  manages and serves as the  investment
adviser for other mutual  funds and is an  investment  adviser to certain  other
institutional accounts. The executive offices of PMC, PGI and PFD are located at
60 State Street, Boston, Massachusetts 02109. In an effort to avoid conflicts of
interest with the Fund, the Fund, PMC and BFS, the subadviser to the Fund,  have
adopted a Code of  Ethics  that is  designed  to  maintain  a high  standard  of
personal  conduct by directing that all personnel  defer to the interests of the
Fund and its shareholders in making personal securities transactions.

       Under  the  terms of its  contract  with the  Fund,  PMC  assists  in the
management  of the  Fund and is  authorized  in its  discretion  to buy and sell
securities  for the  account of the Fund.  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) charges and  expenses  for fund  accounting,  pricing and
appraisal services and related overhead,  including, to the extent such services
are performed by personnel of PMC or its affiliates, office space and facilities
and personnel compensation,  training and benefits; (b) the charges and expenses
of auditors; (c) the charges and expenses of any custodian, transfer agent, plan
agent,  dividend  disbursing  agent  and  registrar  appointed  by the Fund with
respect to the Fund;  (d) issue and transfer  taxes,  chargeable  to the Fund in
connection  with  securities  transactions  to which  the  Fund is a party;  (e)
insurance  premiums,  interest  charges,  dues and fees for  membership in trade
associations  and all taxes and  corporate  fees payable by the Fund to federal,
state  or  other  governmental  agencies;  (f) fees  and  expenses  involved  in
registering and maintaining registrations of the Fund and/or its shares with the
SEC, state or blue sky securities agencies and foreign countries,  including the
preparation of Prospectuses and Statements of Additional  Information for filing
with the SEC; (g) all expenses of  shareholders'  and Trustees'  meetings and of
preparing, printing and distributing prospectuses, notices, proxy statements and
all  reports to  shareholders  and to  governmental  agencies;  (h)  charges and
expenses of legal counsel to the Fund and the Trustees;  (i)  distribution  fees
paid by the Fund pursuant to the 1940 Act; (j) compensation of those Trustees of
the Fund who are not  affiliated  with or  interested  persons of PMC,  the Fund
(other than as  Trustees),  PGI or PFD; (j) the cost of  preparing  and printing
share   certificates;   (k)  interest  on  borrowed   money,  if  any;  and  (l)
organizational   expenses  of  the  Fund.  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  where 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 any Pioneer  mutual fund or other funds for which PMC or any other  affiliate
or  subsidiary  serves as  investment  adviser or manager.  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% per  annum of the  Fund's  average  daily  net  assets.  The fee is  normally
computed daily and paid monthly. See "Expense Information" in the Prospectus and
"Investment Adviser" in the Statement of Additional Information.

      THE REAL ESTATE  SUBADVISER.  BFS is an affiliate of The Boston  Financial
Group  Limited  Partnership,   a  Massachusetts   limited  partnership  ("Boston
Financial"), which together with a predecessor business has extensive experience
and expertise in placing,  evaluating and providing  advice on a variety of real
estate related  investments  since 1969 for  individuals,  institutions and real
estate professionals.  Several other affiliates of BFS also provide a variety of
financial,  consulting  and  management  services to real estate  investors  and
developers. As one of the largest real estate asset managers in the U.S., Boston
Financial oversees investment in over $6 billion of properties in 49 states. The
company serves over 37,000  investors with equity  contributions in excess of $2
billion in real estate  investments.  In its capacity as subadviser to the Fund,
BFS (i) identifies and analyzes real estate industry  companies,  including real
estate properties and other permissible  investments for the Fund, (ii) analyzes
market  conditions  affecting  the real estate  industry  generally and specific
geographical and securities markets in which the Fund may invest or is invested,
(iii) continuously  reviews and analyzes the investments in the Fund's portfolio
and (iv) furnishes advisory reports based on such analysis to PMC.

       Mr. Fred N. Pratt, Jr. has the ultimate responsibility for overseeing the
provisions of subadvisory services to the Fund. Mr. Pratt is President and Chief
Executive  Officer of Boston  Financial,  a Director of BFS and a Trustee of the
Fund.  Mr.  Pratt has worked in the real estate  industry  since 1969.  Mr. Mark
Howard-Johnson,  a Vice  President  of BFS,  is  primarily  responsible  for the
day-to-day  provision of  subadvisory  services to the Fund since  September 30,
1996. Mr. Howard-Johnson has worked as a real estate analyst since 1994.

       As compensation for its subadvisory services, PMC (and not the Fund) pays
BFS a subadvisory  fee equal to 0.25% per annum of the Fund's  average daily net
assets up to $27 million and 0.50% of average  daily net assets in excess of $27
million.  After written notice to BFS, the subadvisory fee payable by PMC to BFS
would be  reduced  proportionally  to the  extent  that PMC  elects to utilize a
portion of the management fees paid to PMC by the Fund to make payments to third
parties.

       The  executive  offices of BFS are  located at 101 Arch  Street,  Boston,
Massachusetts  02110. BFS is a registered  broker-dealer and may act as a broker
in connection  with the sale of shares of the Fund under a sales  agreement with
PFD.

  V. FUND SHARES

       The Fund  continuously  offers four Classes of shares designated as Class
A, Class B, Class C and Class Y shares.  Class A, Class B and Class C shares are
offered in a separate  prospectus which may be obtained by contacting your sales
representative or by calling PSC at 1-888-294-4480.

      Class Y shares  are sold at net asset  value,  without  either an  initial
sales  charge or a  contingent  deferred  sales  charge.  Class Y shares are not
subject to any ongoing service fee or distribution fee and do not convert to any
other class of shares.  Class Y shares are described  more fully in  "Purchasing
Class Y Shares" in this Prospectus.

       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.
Shares sold outside the U.S. to persons who are not U.S. citizens may be subject
to  different  sales  charges,  contingent  deferred  sales  charges  and dealer
compensation arrangements in accordance with local laws and business practices.

  VI. SHARE PRICE

       Class Y shares of the Fund are sold at the net asset value per share. The
net asset  value per share of each Class of the Fund 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.  The net asset value per share of
Class Y shares  will  generally  be higher than the net asset value per share of
the Fund's other three classes of shares  because Class Y shares are not subject
to any ongoing  distribution  fee, and certain other expenses are expected to be
lower.

       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  may be 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. PURCHASING  CLASS Y SHARES

       To open an account for an individual or other non-institutional investor,
a  completed  Account   Application  must  be  received  by  Pioneering  Service
Corporation  ("PSC") by mail or by fax prior to the  purchase of Class Y shares.
All other  investors  should  call PSC at  1-888-294-4480  to obtain an  account
set-up kit and to obtain an account number.  A bank wire address of record (your
predesignated  bank  account") must be provided to PSC at the time an account is
established.

       The minimum initial investment for Class Y shares is $5 million which may
be invested  in one or more of the Pioneer  mutual  funds that  currently  offer
Class Y shares. There is no minimum additional investment amount. Class Y shares
will be purchased at the net asset value per share next  computed  after receipt
of a purchase  order  without the  imposition of an initial sales charge and are
not subject to a contingent deferred sales charge. All purchases must be made in
U.S. dollars.

       The $5 million minimum investment requirement will be waived if:

(i)    a trust company or bank trust department is initially  investing at least
       $1 million in any of the  Pioneer  mutual  funds and,  at the time of the
       purchase,  such assets are held in a  fiduciary,  advisory,  custodial or
       similar  capacity over which the trust  company or bank trust  department
       has full or shared investment discretion; or

(ii)   the  investment  is made by an employer  sponsored  retirement  plan that
       meets the  requirements of Section 401, 403 or 457 of the Code,  provided
       that the number of employees  covered by the plan is 5,000 or more or the
       plan has assets of $25 million or more; or

(iii)  the  investment  is at least $1 million and the purchaser is an insurance
       company separate account; or

(iv)   the  investment  is  made  by  an  employer  sponsored   retirement  plan
       established for the benefit of (1) employees of PGI or employees of PGI's
       affiliates or (2) employees of  broker-dealers  who have a Class Y shares
       sales agreement with PFD.

PAYMENT BY WIRE.  Funds may be wired in payment of a request to purchase Class Y
shares provided that such funds are wired to a Class Y shares account. See above
for  information  on  establishing  an  account.  To wire  funds in payment of a
request to purchase Class Y shares instruct your bank to wire funds to:

Receiving Bank    State Street Bank and Trust Company
Address                    225 Franklin Street
                           Boston, MA 02101
ABA Routing No.   011000028
For further credit to:     Shareholder Name
                           Existing Pioneer Account No.
                           Pioneer Real Estate Shares

       A  request  to  purchase  shares  must  be  received  by PSC  or by  your
broker-dealer  by the close of regular  trading of the Exchange  (currently 4:00
p.m.  Eastern time) in order to purchase shares at the price  determined on that
day.  Funds wired in payment of such  requests  must be received by State Street
Bank and Trust  Company  by 11:00 a.m.  Eastern  time on the next  business  day
following  receipt of the  request to  purchase  shares.  IF WIRED FUNDS ARE NOT
RECEIVED BY PSC BY 11:00 A.M. OF THE NEXT BUSINESS DAY FOLLOWING  RECEIPT OF THE
REQUEST TO PURCHASE SHARES,  THE TRANSACTION WILL BE CANCELED AT THE EXPENSE AND
RISK OF THE  PURCHASER.  Wire  transfers  normally  take  two or more  hours  to
complete and a fee may be charged by the sending  bank.  Wire  transfers  may be
restricted on holidays and at certain other times.  Questions on wire  transfers
should be directed to PSC or your broker-dealer.

       BY MAIL.  Purchases  of Class Y shares  may  always be made by mail.  For
accounts  registered to individuals or  non-institutional  investors,  make your
check  payable to  Pioneer  Real  Estate  Shares  and mail a  completed  Account
Application  to PSC at: P.O. Box 9150,  Boston,  Massachusetts  02205-8573.  For
accounts registered to institutions, completed account set-up kit materials must
be sent to PSC with  payment.  Checks  written  on  non-U.S.  banks  will  delay
purchases until U.S. funds are received and a collection charge may be imposed.

       BROKER-DEALERS.  An order for Class Y shares  received by a broker-dealer
prior to the close of regular  trading on the Exchange is confirmed at the price
for Class Y shares as determined at the close of regular trading on the Exchange
on the day the order is received, provided the order is received by PFD from the
broker-dealer  prior to PFD's  close of  business  (usually,  5:30 p.m.  Eastern
time), except as described above for wire transfers. 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.  REDEEMING  CLASS Y SHARES  Class Y shares  will be  redeemed at the share
price next  calculated  after a redemption  request is received in good order as
described below.  Redemption  proceeds  generally will be sent to the registered
owner by check or by wire transfer, normally within seven days after the request
is received in good order.  The Fund  reserves the right to withhold  payment of
the redemption  proceeds until checks or wire transfers  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.  Class Y shares  may be  redeemed  by  delivering  a written
request,  signed  by all  registered  owners,  in good  order to PSC.  A written
request,  including a signature guarantee, must be used to redeem Class Y shares
if any of the following applies:

o     the requested  redemption is for over $100,000 and there is no record of a
      predesignated bank account,
o     the requested redemption is for over $100,000 and the account registration
      or address of record has changed within the last 30 days,
o     the requested redemption is for over $5 million,
o     the check for the amount of the redemption proceeds is not being mailed to
o     the address of record, the check for the amount of the redemption proceeds
      is not being made payable to the account's record owners, or
o     the  redemption  proceeds are being  transferred  to a Pioneer mutual fund
      account with a different registration.

       Include in the request the account's  registration name, the Fund's name,
the 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.  Redemption  requests for accounts  registered in the name of a
corporation  or other  fiduciary  must  name an  authorized  person  and must be
accompanied by a certified copy of a current corporate  resolution,  certificate
of  incumbency or similar legal  document  showing that the named  individual is
authorized to act on behalf of the record owner.  Unless  instructed  otherwise,
PSC will send the proceeds of the  redemption by check to the address of record.
For more information, contact PSC at 1-800-888-294-4480.

       Written  requests  will not be processed  until they are received in good
order by PSC. Good order means that there are no outstanding  claims or requests
to hold redemptions on the account,  any share  certificates are endorsed by the
record owner(s) exactly as the shares are registered and the signature(s) on the
share  certificate  are  guaranteed by an eligible  guarantor.  A bank,  broker,
dealer,  credit union (if authorized  under state law),  securities  exchange or
association,  clearing agency or savings  association  will generally be able to
provide a  signature  guarantee.  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 1-888-294-4480.

         A signature  guarantee  must also  accompany any request to change your
predesignated bank account information.

       BY TELEPHONE OR FAX. Class Y share accounts are automatically  authorized
to have the telephone  redemption  privilege unless  indicated  otherwise on the
Account Application or by writing to PSC. Proper account  identification will be
required for each telephone redemption.  A maximum of $5 million per account per
day may be redeemed by telephone or fax if PSC has a predesignated  bank account
number on record.  If there is no  predesignated  bank account number on file, a
maximum of $100,000  may be  redeemed by  telephone  or fax.  The  proceeds of a
telephone  or fax  redemption  may be  received by bank wire,  electronic  funds
transfer or by check.  Proceeds of a telephone or fax request  will  normally be
mailed or transmitted the next business day.

      To  redeem  by   telephone,   see   "Shareholder   Services  -   Telephone
Transactions" for more information.

       To redeem by fax, send your redemption request to 1-888-294-4485.

       To receive the proceeds by bank wire:  the  proceeds  must be sent to the
bank wire address of record which must have been properly  predesignated  either
on your  Account  Application  or on an Account  Options Form and which must not
have changed in the last 30 days.

       To receive the proceeds by check:  the check must be made payable exactly
as the account is registered and the check must be sent to the address of record
which must not have changed in the last 30 days.

       You may always elect to deliver redemption instructions to PSC by mail.

       REDEEMING SHARES THROUGH A 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.
Broker-dealers  must receive redemption  requests prior to the close of business
of the Exchange and must  transmit each  redemption  request to PFD before PFD's
close of business to receive that day's  redemption  price.  Broker-dealers  are
responsible for providing all necessary  documentation to PFD and may charge for
their services.

       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
unless  the  account  qualifies  as  tax-exempt.  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.


       BY MAIL.  Purchases  of Class Y shares may  always be made by mail.  Make
your check  payable to Pioneer Real Estate  Shares and mail a completed  Account
Application to PSC at: P.O. Box 9150, Boston,  Massachusetts 02205-8573.  Checks
written on non-U.S. banks will delay purchases until U.S. funds are received and
a collection charge may be imposed.

IX. EXCHANGING CLASS Y SHARES

       Exchanges  of Class Y shares 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 Class Y shares. A new Pioneer mutual fund account
opened  through an exchange  must have a  registration  identical to that on the
original account.

       PSC will process  exchanges only after  receiving an exchange  request in
good order.  Exchange requests received by PSC before the close of the Exchange,
generally  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.  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.

       TELEPHONE AND FAX  EXCHANGES.  Class Y share  accounts are  automatically
authorized to have the telephone exchange  privilege unless indicated  otherwise
on the Account  Application or by writing to PSC. Proper account  identification
will be  required  for  each  telephone  exchange.  Telephone  exchanges  or fax
exchanges of Class Y shares may not exceed $5 million per account per day.  Each
telephone exchange request will be recorded. See "Telephone Transactions" below.

       WRITTEN EXCHANGES. Class Y shares may be exchanged by sending a letter of
instruction to PSC.  Include in your letter the record name on the account,  the
name of the Pioneer  mutual  fund out of which to  exchange  and the name of the
Pioneer  mutual fund into which to  exchange,  the 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.  Written documentation may be required for
accounts registered in the name of a corporation or fiduciary.

  X. DISTRIBUTION OF FUND SHARES

       PFD incurs the expenses of distributing  the Fund's Class Y shares,  none
of which is reimbursed or paid for by the Fund. These expenses include fees paid
to, or on account of,  broker-dealers  and other qualifying  institutions  which
have sales agreements with PFD, advertising  expenses,  the cost of printing and
mailing  prospectuses  to  potential  investors  and other  direct and  indirect
expenses associated with the sale of Fund's Class Y shares.

       PFD or its  affiliates  may make  payments  out of its own  resources  to
dealers and other persons who distribute  shares of the Fund,  including Class Y
shares.  Such  payments may be calculated by reference to the net asset value of
shares sold by such person or otherwise. Dealers and other persons may from time
to time be required to meet certain  criteria in order to receive such payments.
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.

       The Fund has  adopted a Plan of  Distribution  for each  Class of shares,
other  than Class Y shares,  in  accordance  with Rule 12b-1  under the 1940 Act
pursuant  to  which  certain  distribution  fees  are  paid  to  PFD.  For  more
information,   see   "Distribution   Plans"  in  the   Statement  of  Additional
Information.

  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 tax on income and capital gains  distributed
to shareholders as required under the Code.

       Under the Code, the Fund will be subject to a nondeductible 4% excise tax
on a portion of its undistributed  ordinary 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,
usually in December.  Distributions  from net short-term  capital gains, if any,
may be paid with such dividends;  dividends from income and/or capital gains may
also be paid at such  other  times  as may be  necessary  for the  Fund to avoid
federal  income  or  excise  tax.  Generally,  dividends  from  the  Fund's  net
investment  income,  market discount income,  net short-term  capital gains, and
certain  net  foreign  exchange  gains are  taxable  under the Code 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 shareholder  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 to shareholders annually. For further information
on  the  distribution  options  available  to  shareholders,  see  "Distribution
Options" below.

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

       The Fund may be  subject to foreign  withholding  taxes or other  foreign
taxes on income (possibly including, in some cases, capital gains) on certain of
its  foreign  investments  which will  reduce the yield on or return  from those
investments.

       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  shareholder's  correct  taxpayer  identification
number and certification  that the number is correct and that the shareholder is
not subject to backup withholding or if the Fund receives notice from the IRS or
a broker that such withholding applies.

       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 advisors  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
9150,  Boston,  Massachusetts  02205-8573.  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 as transactions occur..

  FINANCIAL REPORTS AND TAX INFORMATION

       As  a  shareholder,   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 capital gains
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.

       If you elect to receive either dividends or capital gains or both in cash
and a  distribution  check issued to you is returned by the U. S. Postal Service
as not  deliverable or a distribution  check remains  uncashed for six months or
more, the amount of the check may be reinvested in your account. Such additional
shares will be purchased at the then current net asset value.  Furthermore,  the
distribution  option  on  the  account  will  automatically  be  changed  to the
reinvestment option until such time as you request a different option by writing
to PSC.

TELEPHONE TRANSACTIONS

       Class  Y  accounts  are   automatically   authorized  to  have  telephone
transaction  privileges as described above. To redeem or exchange Class Y shares
by telephone,  call 1-888-294-4480  between the hours of 9:00 a.m. and 6:00 p.m.
Eastern time on weekdays.  See "Selling Class Y Shares" and "Exchanging  Class Y
Shares" 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
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
shareholder access to current information on Pioneer mutual fund accounts and to
the prices and yields of all publicly  available Pioneer mutual funds.  Computer
assisted  telephone  purchases,  exchanges and redemptions of Class Y shares are
not currently available through FactFoneSM.

                           ---------------------
The options and services available to shareholders 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 establish or
revise  many of them on an existing  account by  completing  an Account  Options
Form, which you may obtain by calling 1-888-294-4480.

  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  shareholder  at the then  current net
asset value per share (less any applicable  contingent deferred sales charge for
Class A, Class B and Class C share transactions).  The Fund is not required, and
does not intend, to hold annual  shareholder  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 shareholder  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 four  classes of shares,  designated
Class A, Class B, Class C and Class Y. 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. A Rule 12b-1 distribution plan has not been adopted with
respect to the Class Y shares of the Fund (see  "Distribution of Class Y Shares"
for more information).

       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
certificates;  certificates  will not normally be issued.  The Fund reserves the
right  to  charge  a fee for  the  issuance  of  Class  A  shares  certificates;
certificates will not be issued for Class B, Class C or Class Y shares.

  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. 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 indices,
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 U.S.  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 U.S.  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.

       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
U.S. 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.  The Fund may also  invest up to 15% of its net  assets in  illiquid
investments,  which  includes  securities  that are not readily  marketable  and
repurchase  agreements  maturing in more than seven days.  The Board of Trustees
has adopted  guidelines  and delegated to PMC the daily  function of determining
and  monitoring  the  liquidity of  portfolio  securities.  The Board,  however,
retains   sufficient   oversight   and  is   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 monitors 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 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.  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
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 Prospectuses of the Fund identify 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 Prospectuses.
    

LOWER-RATED DEBT SECURITIES AND ASSOCIATED RISKS

   
         As  described  in the  Prospectuses,  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
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.

         Proposed  federal  laws  designed  to limit  the use,  or tax and other
advantages,  of junk bond securities could adversely affect the Fund's net asset
value to the extent that the Fund invests in lower-rated debt  securities.  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.

         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
financial  standards and  requirements  comparable to those applicable to United
States ("U.S.")  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 U.S.  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 U.S. companies. Transaction costs on foreign securities exchanges are
generally higher than in the United States.

         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 U.S. 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.

         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.

         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
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
securities.  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
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 net  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
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,  PMC  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
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 a  fundamental  policy  of  the  Fund  not to  concentrate  its
investments in securities of companies in any particular industry. Following the
current opinion of the staff of the Securities and Exchange  Commission ("SEC"),
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
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.

         (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;  provided,  however,  that the Fund
may  invest up to 10% of its total  assets in shares of real  estate  investment
trusts that are illiquid.

         (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.

         These  restrictions  may not be changed  without  the  approval  of the
regulatory agencies in such states or foreign countries.

Note 1 This fund is a closed-end fund.

   
Note     2 This is a series  of ten  separate  portfolios  designed  to  provide

         insurance  contracts  of various  insurance  companies  or for  certain
         qualified pension plans.

         PMC also  manages  the  investments  of certain  institutional  private
accounts.  As of December 31, 1997,  to the knowledge of the Fund, no officer or
Trustee of the Fund owned 5% or more of the  issued  and  outstanding  shares of
PGI, except Mr. Cogan who then owned  approximately  14% of such shares. As of a
date no earlier than 30 days prior to the date of this  Statement of  Additional
Information  ("SAI"),  the  Trustees  and  officers  of the  Fund  owned  in the
aggregate less than 2% of the  outstanding  shares of the Fund and there were no
shareholders  of record  who owned 5% or more of the Fund's  outstanding  voting
securities,  except  MLPF&S For the Sole Benefit of its  Customers,  Mutual Fund
Administration,  4800 Deer Lake Drive East, Third Floor,  Jacksonville,  Florida
32246-6484,  owned  approximately  847,895 (26.48%) of the Class B shares of the
Fund and 319,816 (33.06%) of the Class C shares of the Fund.
    

REMUNERATION OF TRUSTEES

         The Fund  pays no  salaries  or  compensation  to any of its  officers,
however,  the Fund  pays an  annual  trustee's  fee to each  Trustee  who is not
affiliated  with PMC, PGI, PFD or PSC consisting of two  components:  (a) a base
fee of $500 and (b) a variable  fee,  calculated on the basis of the average net
assets of the Fund. In addition, the Fund pays a per meeting fee of $100 to each
Trustee who is not  affiliated  with PMC, PGI, PFD or PSC. The Fund also pays an
annual  committee  participation  fee  to  trustees  who  serve  as  members  of
committees  established  to act on behalf of one or more of the  Pioneer  mutual
funds.  Committee  fees are  allocated  to the Fund on the  basis of the  Fund's
average net assets.  Each Trustee who is a member of the Audit Committee for the
Pioneer mutual funds receives an annual fee equal to 10% of the aggregate annual
trustee's fee,  except the Committee  Chair who receive an annual  trustee's fee
equal to 20% of the  aggregate  annual  trustee's  fee.  Members of the  Pricing
Committee for the Pioneer  mutual funds,  as well as any other  committee  which
renders  material  functional  services to the Board of Trustees for the Pioneer
mutual  funds,  receive an annual fee equal to 5% of the annual  trustee's  fee,
except the Committee Chair who receives an annual  trustee's fee equal to 10% of
the annual trustee's fee. Any such fees paid to affiliates or interested persons
of  PGI,  PMC,  PFD or PSC are  reimbursed  to the  Fund  under  its  Management
Contract.

4.       ADVISORY SERVICES

THE ADVISER.
   
         As  stated  in  the   Prospectus,   PMC,  60  State   Street,   Boston,
Massachusetts  02109,  serves as the Fund's investment  adviser.  The Management
Contract  is  renewable  annually  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,  as the case may be, or a
majority of the Fund's  outstanding  voting  securities  and the giving of sixty
days' written notice.
    

         As compensation for its investment advisory and management services and
expenses incurred,  PMC is entitled to a management fee at the rate of 1.00% per
annum of the Fund's average daily net assets. The fee is computed daily and paid
monthly.  Prior to October  22,  1996,  PMC  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%
of the Fund's  average daily net assets;  the portion of the Fund-wide  expenses
attributable  to Class B and Class C shares were reduced only to the extent they
were  reduced for Class A shares.  From the Fund's  inception  through  July 17,
1995, Pioneer Winthrop Advisers ("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 from  October 25, 1993  through June 30, 1994,  July 1,
1994 through  December  31, 1994 and January 1, 1995 through July 17, 1995,  the
Fund  would  have paid or  accrued  total  management  fees to PWA of  $103,371,
$141,284  and  $142,839,  respectively,  but  $45,812,  $73,158,  and  $117,002,
respectively,  of such  fees  were  not  imposed  pursuant  to  PWA's  voluntary
agreement  described  above.  For the period from July 18, 1995 through December
31, 1995 and for the fiscal year ended  December 31,  1996,  the Fund would have
paid  or  accrued  total  management  fees  to PMC  of  $122,260  and  $428,114,
respectively,  but $99,216  and  $145,879,  respectively,  of such fees were not
imposed pursuant to PMC's voluntary agreement described above.

         For the periods from  October 25, 1993  through June 30, 1994,  July 1,
1994 through  December  31, 1994 and January 1, 1995 through July 17, 1995,  PWA
paid or accrued total  subadvisory fees to PMC and WALP  approximately  $34,535,
$26,010 and $15,502, respectively.

         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.

THE SUBADVISER.

   
         Boston Financial  Securities,  Inc. ("BFS"),  101 Arch Street,  Boston,
Massachusetts 02110, serves as the Fund's subadviser.  The subadvisory agreement
among the Fund,  PMC and BFS is renewable  annually 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 of  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,  as the case may be,
or a majority of the Fund's  outstanding  voting securities and the giving of 60
days' written notice.
    

         As  compensation  for  its  subadvisory   services,   PMC  pays  BFS  a
subadvisory  fee equal to 0.25% per annum of the Fund's average daily net assets
up to $27  million  and  0.50% of  average  daily  net  assets  in excess of $27
million. The fee is computed daily and paid monthly. The subadvisory fee payable
by PMC to BFS will be  reduced  proportionally  to the  extent  that PMC,  after
written notice to BFS,  elects to utilize a portion of the management  fees paid
to PMC by the  Fund to make  payments  to  third  parties.  BFS is a  registered
broker-dealer  and may in the future act as a broker in connection with the sale
of shares of the Fund under a selling agreement with PFD.

         As of December 31, 1996, the following  individuals owned  beneficially
more than 10% of the  outstanding  common  stock of BFS:  Randolph  G  Hawthorne
(11.17%),  Fred N. Pratt,  Jr.  (12.98%),  William B  Haynsworth  (11.24%).  The
address  for  each  of  these  individuals  is BFS,  101  Arch  Street,  Boston,
Massachusetts 02110.

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
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.

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

CLASS A PLAN

         Pursuant  to  the  Class  A  Plan  the  Fund  reimburses  PFD  for  its
expenditures in financing certain activities primarily intended to result in the
sale of Class A  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
shares.

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 selling
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's  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
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  "Distribution  Plans" in the Prospectus).
When a broker-dealer  sells Class B shares and elects,  with PFD's approval,  to
waive its right to receive the  commissions  normally paid on the sale,  PFD may
cause all or a portion of the  distribution  fees described  above to be paid to
that broker-dealer.

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 selling 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's 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  net  asset  value  of  such  shares  and
additional  compensation at a rate of up to 0.75% of the net asset value of 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 "Distribution Plans" in the Prospectus). ).
When a broker-dealer  sells Class C shares and elects,  with PFD's approval,  to
waive its right to receive the  commissions  normally paid on the sale,  PFD may
cause all or a portion of the  distribution  fees described  above to be paid to
that broker-dealer.

   
Class Y Shares

   PFD incurs the expenses of  distributing  the Fund's Class Y shares,  none of
which  are  reimbursed  or paid for by the  Fund.  These  expenses  include  any
commissions or account servicing fees paid to, or on account of,  broker-dealers
which  have  selling  agreements  with  PFD and  certain  qualifying  registered
investment advisers and other financial institutions.
    

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
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 December 31, 1995, the Fund incurred total Class A distribution  fees of
$35,321  and  $61,755,  respectively.  During  the fiscal  year  ended  December
31,1996,  the Fund incurred total distribution fees pursuant to the Fund's Class
A Plan,  Class B Plan,  and Class C Plan,  respectively,  as  follows:  $79,357,
$50,464  and  $13,398.  The  distribution  fees  were paid by the Fund to PFD in
reimbursement  of expenses  related to servicing of shareholder  accounts and to
compensating dealers and sales personnel.

   
           Redemptions  of each class of shares  (except  Class Y shares) may be
subject to a CDSC. A CDSC of 1.00% may be imposed on  redemptions of certain net
asset value  purchases of Class A shares  within one year of  purchase.  Class B
shares that are  redeemed  within 6 years of  purchase  are subject to a CDSC at
declining  rates  beginning at 4% based on the lower of the cost or market value
of the shares being  redeemed.  Redemptions of Class C shares within one year of
purchase are subject to a CDSC of 1.00%.  During the fiscal year ended  December
31, 1996, CDSCs, in the amount of approximately $677 were paid to PFD.
    

6.         SHAREHOLDER SERVICING/TRANSFER AGENT

   
           The  Fund  has  contracted   with  PSC,  60  State  Street,   Boston,
Massachusetts  02109,  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,  as the
case may be, or a majority of the Fund's  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.

   
           PSC receives  from the Fund an annual fee of $22.75 for each Class A,
Class  B,  Class C and  Class Y  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. The Fund may compensate entities which have agreed to provide certain
sub-accounting   services   such  as   specific   transaction   processing   and
recordkeeping  services.  Any such  payments by the Fund would be in lieu of the
per account fee which would otherwise be paid by the Fund to PSC.
    

7.       CUSTODIAN

   
         Brown  Brothers  Harriman & Co.  (the  "Custodian"),  40 Water  Street,
Boston,  Massachusetts  02109,  is the  custodian  of  the  Fund's  assets.  The
Custodian's responsibilities include safekeeping and controlling the Fund's cash
and securities in the U.S. 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 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 U.S. or in recognized  central  depositories in
foreign countries.

8.       PRINCIPAL UNDERWRITER

   
         Pioneer Funds Distributor, Inc., 60 State Street, Boston, Massachusetts
02109,  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 purchase of assets,  merger or
reorganization.
    

           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
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  December 31, 1995,
net  underwriting  commissions  earned by PFD in connection with its offering of
Fund shares  were  approximately  $66,304,  $27,497  and  $29,767.  For the same
periods,  commissions reallowed to dealers by PFD were approximately $1,124,000,
$186,213 and $187,036,  respectively.  During the fiscal year ended December 31,
1996,  net  underwriting  commissions  retained  by PFD in  connection  with its
offering of Fund shares were  approximately  $61,469.  Commissions  reallowed to
dealers by PFD were approximately  $1,142,385.  See "Underwriting  Agreement and
Distribution  Plan"  above for a  description  of the terms of the  Underwriting
Agreement with PFD.

9.         INDEPENDENT PUBLIC ACCOUNTANTS

           Arthur  Andersen  LLP, 225  Franklin  Street,  Boston,  Massachusetts
02110, 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
Management  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 U.S.)
and are generally higher than in the U.S..
    

         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.

         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 its
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  Pioneer mutual fund 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  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  December 31, 1995,
the Fund paid or accrued  aggregate  brokerage and  underwriting  commissions of
approximately $170,534,  $213,710 and $18,000,  respectively.  During the fiscal
period ended December 31, 1996, the Fund paid or accrued aggregate brokerage and
underwriting commissions of approximately $224,000.

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.  These requirements
relate to the sources of the Fund's income,  the  diversification  of its assets
and the distribution of its income to  shareholders.  If the Fund meets all such
requirements and distributes to its shareholders,  in accordance with the Code's
timing requirements, all investment company taxable income and net capital gain,
if any,  which it earns,  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 and futures 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 stock,  securities  and certain other  positions  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.  For purposes of the 90% income  test,  income the Fund earns from
equity interests in certain entities that are not treated as corporations (e.g.,
are treated as partnerships or trusts) for U.S. tax purposes will generally have
the same character for the Fund as in the hands of such entities;  consequently,
the Fund may be required to limit its equity  investments  in such entities that
earn fee income,  rental income, or other nonqualifying income.  Similarly,  the
Fund may need to limit its  holdings  of and income  from any  direct  ownership
interests  that it may  acquire  in  real  estate  in  order  to seek to  ensure
satisfaction of the 90% income test.

         Dividends from investment  company  taxable income,  which includes net
investment  income,  net  short-term  capital  gain in excess  of net  long-term
capital loss, and certain net foreign  exchange  gains,  are taxable as ordinary
income,  whether received in cash or reinvested in additional shares.  Dividends
from net  long-term  capital gain in excess of net  short-term  capital loss, if
any, whether received in cash or reinvested in 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.

         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.   Any
transactions  in foreign  currency  that are not directly  related to the Fund's
investments  in stock or securities  (or its options or futures  contracts  with
respect  to stock or  securities)  may need to be limited in order to enable the
Fund to satisfy the limitations described in the second paragraph above that are
applicable to the income or gains recognized by a regulated  investment company.
If the net foreign exchange loss for a year were to exceed the Fund's investment
company  taxable income  (computed  without regard to such loss),  the resulting
ordinary  loss  for  such  year  would  not be  deductible  by the  Fund  or its
shareholders in future years.

         If the Fund acquires any equity interest  (under proposed  regulations,
generally  including  not only  stock but also an option  to  acquire  stock) in
certain  foreign  corporations  that  receive at least 75% of their annual gross
income from passive sources (such as interest,  dividends,  rents,  royalties or
capital gain) or hold at least 50% of their assets in investments producing such
passive  income  ("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.  Certain
elections may, if available,  ameliorate these adverse tax consequences, but any
such election would require the Fund to recognize taxable income or gain without
the concurrent receipt of cash. The Fund may limit and/or manage its holdings in
passive foreign  investment  companies to minimize its tax liability or maximize
its return from these investments.

         The Fund may invest in debt  obligations  that are in the lowest rating
categories or are unrated,  including debt  obligations of issuers not currently
paying interest or who are in default.  Investments in debt obligations that are
at risk of or in default  present 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 seek to  ensure  that it  distributes
sufficient income to preserve its status as a regulated  investment  company and
does not become subject to federal income or excise tax.

         If the Fund invests in certain pay-in-kind  securities  ("PIKs"),  zero
coupon  securities,  deferred  interest  securities  or, in  general,  any other
securities  with original  issue  discount (or with market  discount if the Fund
elects to include  market  discount in income  currently),  the Fund must accrue
income on such  investments for each taxable year, which generally will be prior
to the  receipt  of the  corresponding  cash  payments.  However,  the Fund must
distribute,  at least  annually,  all or  substantially  all of its net  income,
including  such  accrued  income,  to  shareholders  to qualify  as a  regulated
investment  company  under the Code and avoid  Federal  income and excise taxes.
Therefore,  the Fund may  have to  dispose  of its  portfolio  securities  under
disadvantageous  circumstances  to generate cash, or may have to leverage itself
by borrowing the cash, to satisfy distribution requirements.

         For federal income tax purposes, the Fund is permitted to carry forward
a net capital loss for any year to offset its capital gains,  if any, during the
eight years  following  the year of the loss. To the extent  subsequent  capital
gains are offset by such  losses,  they  would not result in federal  income tax
liability to the Fund and therefore are not expected to be  distributed  as such
to shareholders.  As of the end of its most recent taxable year, the Fund had no
capital loss carryforwards.

         At the time of an investor's  purchase of Fund shares, a portion of the
purchase price may be attributable to realized or unrealized appreciation in the
Fund's  portfolio or  undistributed  taxable  income of the Fund.  Consequently,
subsequent distributions on these shares from such appreciation or income may be
taxable to such  investor even if the net asset value of the  investor's  shares
is, as a result of the distributions, reduced below the investor's cost for such
shares and the distributions economically represent a return of a portion of the
investment.

         Redemptions  and exchanges are taxable  events.  Any loss realized by a
shareholder upon the redemption,  exchange or other disposition 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 Class A shares redeemed or exchanged have been held for
less than 91 days, (1) in the case of a reinvestment at net asset value pursuant
to the  reinvestment  privilege,  the sales  charge  paid on such  shares is not
included in their tax basis under the Code,  and (2) in the 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
redemptions or other  dispositions of shares may be disallowed under "wash sale"
rules in the  event of other  investments  in the  Fund  (including  those  made
pursuant to reinvestment of dividends and/or capital gain distributions)  within
a  period  of 61 days  beginning  30 days  before  and  ending  30 days  after a
redemption  or other  disposition  of  shares.  In such a case,  the  disallowed
portion of any loss would be  included  in the  federal  tax basis of the shares
acquired in the other investments.

         Options written or purchased and futures  contracts entered into by the
Fund on certain  securities or 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 performed or closed out. The tax rules applicable to
these  contracts 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  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.  Certain tax  elections may be
available that would enable the Fund to ameliorate  some adverse  effects of the
tax rules  described in this  paragraph.  The tax rules  applicable  to options,
futures  contracts and straddles may affect the amount,  timing and character of
the Fund's income and losses and hence of its distributions to shareholders.

         For  purposes  of  the  70%   dividends-received   deduction  generally
available to corporations  under the Code,  dividends  received by the Fund 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) held
in an  unleveraged  position and  distributed  and designated by the Fund may be
treated as qualifying  dividends.  Any corporate  shareholder should consult its
tax advisor  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.  In order to qualify  for the  deduction,
corporate  shareholders must meet the minimum holding period  requirement stated
above with respect to their Fund shares,  taking into account any holding period
reductions from certain hedging or other transactions or positions that diminish
their risk of loss with  respect to their Fund  shares,  and,  if they borrow to
acquire  Fund  shares,  they 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,  including  taxes on interest,  dividends and capital gains,
with respect to its  investments in those  countries.  Tax  conventions  between
certain countries and the U.S. may reduce or eliminate such taxes in some cases.
The Fund does not expect to satisfy the  requirements for passing through to its
shareholders  their pro rata shares of qualified foreign taxes paid by the Fund,
with the result that  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.

         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.

   
         A state income (and possibly local income and/or  intangible  property)
tax  exemption  is  generally  available  to the  extent  (if  any)  the  Fund's
distributions  are  derived  from  interest  on (or,  in the case of  intangible
property  taxes,  the  value of its  assets is  attributable  to)  certain  U.S.
Government  obligations,  provided in some states that  certain  thresholds  for
holdings of such obligations  and/or reporting  requirements are satisfied.  The
Fund will not seek to satisfy any threshold or reporting  requirements  that may
apply in  particular  taxing  jurisdictions,  although  the Fund may in its sole
discretion provide relevant information 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 Internal  Revenue  Service  ("IRS")  regulations.  In
order to avoid this withholding requirement,  shareholders must certify on their
Account  Applications,  or on separate IRS Forms W-9,  that the Social  Security
Number 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.

         If,  as  anticipated,  the Fund  qualifies  as a  regulated  investment
company under the Code, it will not be required to pay any Massachusetts income,
corporate excise or franchise taxes or any Delaware corporation income tax.

         The description of certain federal tax provisions 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. This description does
not address the special tax rules that may be applicable to particular  types of
investors,  such as  financial  institutions,  insurance  companies,  securities
dealers,  or tax-exempt or tax-deferred plans,  accounts or entities.  Investors
other  than U.S.  persons  may be  subject  to  different  U.S.  tax  treatment,
including  a  possible  30%   non-resident   alien  U.S.   withholding  tax  (or
non-resident alien withholding tax at a lower treaty rate) on amounts treated as
ordinary  dividends  from the Fund  and,  unless  an  effective  IRS Form W-8 or
authorized  substitute  for Form W-8 is on file,  to 31% backup  withholding  on
certain other payments from the Fund.  Shareholders should consult their own tax
advisers on these matters and on state, local and other applicable tax laws.

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 four classes of shares of the Fund,
designated  as Class A,  Class B,  Class C and Class Y 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.
    

         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
Declaration  , 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
Declaration  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  Declaration  (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.

         The Declaration  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 Declaration  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  (normally 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,  Martin  Luther King,  Jr. 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 are  received 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 shares are offered at net asset  value  without the
imposition of an initial sales charge, but are subject to a CDSC. Class Y shares
are offered  without an initial sales charge and are not subject to a CDSC.  See
"Fund Share Alternatives" in the Prospectus.

15. SYSTEMATIC WITHDRAWAL PLAN (CLASS A, CLASS B AND CLASS C SHARES ONLY)
    

         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 SWP.  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  deposited,
monthly or quarterly,  directly into a bank account designated by the applicant,
or will be sent to the applicant,  or any person designated by him.  Withdrawals
from Class B and Class C share  accounts are limited as described in "Systematic
Withdrawal  Plan" in the  Prospectus.  A designation of a third party to receive
checks requires an acceptable signature  guarantee.  See "Waiver or Reduction of
Contingent  Deferred  Sales Charge" in the  Prospectus.  Designation  of another
person  to  receive  the  checks  subsequent  to  opening  an  account  must  be
accompanied by a 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.

         SWP  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 SWP 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 INTENT (CLASS A SHARES ONLY)

   
         A Letter of Intent (an "LOI") may be  established by completing the LOI
section of the Account Application.  When you sign the Account Application,  you
agree  to  irrevocably  appoint  PSC  your  attorney-in-fact  to  surrender  for
redemption any or all shares held in escrow with full power of substitution.  An
LOI is not a binding  obligation  upon the investor to purchase,  or the Fund to
sell, the full amount indicated.

         If the total purchases,  less redemptions,  exceed the amount specified
under the LOIand are in an amount  which would  qualify  for a further  quantity
discount,  all transactions will be recomputed on the expiration date of the LOI
to effect the lower sales charge.  Any difference in the sales charge  resulting
from such  recomputation  will be either delivered to you in cash or invested in
additional shares at the lower sales charge.  The dealer, by signing the Account
Application,  agrees to return to PFD, as part of such  retroactive  adjustment,
the excess of the  commission  previously  reallowed  or paid to the dealer over
that which is applicable to the actual amount of the total  purchases  under the
Letter .
    

         If the total  purchases,  less  redemptions,  are less than the  amount
specified  under the Letter , you must remit to PFD any  difference  between the
sales  charge  on the  amount  actually  purchased  and  the  amount  originally
specified in the Letter section of the Account Application.  When the difference
is paid, the shares held in escrow will be deposited to your account.  If you do
not pay the difference in sales charge within 20 days after written request from
PFD or your dealer, PSC, after receiving  instructions from PFD, will redeem the
appropriate  number of  shares  held in escrow to  realize  the  difference  and
release any excess.  See "How to Purchase Fund Shares - Letter of Intent" in the
Prospectus for more information.

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 SEC.

         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.

         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. For Class Y shares, no sales load or deduction of
                   a CDSC is applicable.
    

         T     =   average annual total return

         n     =   number of years

         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,  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 of
a particular class of shares 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.

                                   APPENDIX A

                         MOODY'S CORPORATE BOND RATINGS

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 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 posses many  favorable  investment  attributes 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
other 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.


<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.

Note:  Moody's  applies  numerical  modifiers 1, 2 and 3 in each generic  rating
classification  from Aa  through B in its  corporate  bond  rating  system.  The
modifier 1 indicated  that the  security  ranks in the higher end of its generic
rating category; the modifier 2 indicated a mid-range ranking and the modifier 3
indicates that the issue ranks in the lower end of its generic rating category.
<PAGE>
            STANDARD AND POOR'S RATINGS GROUP CORPORATE BOND RATINGS

AAA

Debt rated AAA has the highest rating assigned by Standard and Poor's.  Capacity
to pay interest and repay principal is extremely strong.

AA

Debt rated AA has a very strong capacity to pay interest and repay principal and
differs from the higher rated issues only in small degree.

A

Debt rated A has a strong capacity to pay interest and repay principal  although
it  is  somewhat  more   susceptible  to  the  adverse  effects  of  changes  in
circumstances and economic conditions than debt in higher rated categories.

BBB

Debt rated BBB is regarded as having an adequate  capacity to pay  interest  and
repay principal.  Whereas it normally exhibits adequate  protection  parameters,
adverse economic conditions of changing circumstances are more likely to lead to
a  weakened  capacity  to pay  interest  and  repay  principal  for debt in this
category than in higher rated categories.

BB

Debt rated BB has less near-term vulnerability to default than other speculative
issues.  However,  it faces major ongoing  uncertainties  or exposure to adverse
business,  financial  or  economic  conditions  which  could lead to  inadequate
capacity to meet timely interest and principal payments.  The BB rating category
is also used for debt  subordinated to senior debt that is assigned an actual or
implied BBB-rating.

B

Debt  rated B has a greater  vulnerability  to  default  but  currently  has the
capacity to meet interest payments and principal  repayments.  Adverse business,
financial or economic  conditions  will likely impair capacity or willingness to
pay interest and repay  principal.  The B rating  category is also used for debt
subordinated  to senior  debt that is  assigned  an actual or  implied BB or BB-
rating.

CCC

Debt rated CCC has a currently  identifiable  vulnerability  to default,  and is
dependent upon  favorable  business,  financial and economic  conditions to meet
timely  payment of interest and repayment of principal.  In the event of adverse
business,  financial  or  economic  conditions,  it is not  likely  to have  the
capacity to pay interest and repay  principal.  The CCC rating  category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
B or B- rating.

<PAGE>
CC

The rating CC is typically  applied to debt  subordinated to senior debt that is
assigned an actual or implied CCC rating.

C

The C rating is typically  applied to debt  subordinated to senior debt which is
assigned  an actual or  implied  CCC- debt  rating.  The C rating may be used to
cover a situation where a bankruptcy  petition has been filed,  but debt service
payments are continued.

CI

The rating CI is reserved for income bonds on which no interest is being paid.

D

Debt rated D is 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 S&P believes that such payments
will be made during such grace  period.  The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

PLUS (+) OR MINUS (-)

The rating from AAA to CCC may be  modified  by the  addition of a plus or minus
sign to show relative standing within the major categories.

                               INDEX DESCRIPTIONS

The following  securities  indices are well-known,  unmanaged measures of market
performance. Advertisements and sales literature for the Fund may refer to these
indices or may present  comparisons  between the performance of the Fund and one
or more of the indices.  Other indices may be used, if appropriate.  The indices
are not available for direct  investment.  The data presented is not meant to be
indicative of the  performance of the Fund,  reflects past  performance and does
not guarantee future results.

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.

U.S. SMALL STOCK INDEX
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.

U.S. 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 U.S. GOVERNMENT BONDS
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 U.S. GOVERNMENT BONDS
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.

6 MONTH CDS
Data sources include the Federal Reserve Bulletin and The Wall Street Journal.

LONG-TERM U.S. 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
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.

U.S. (30 DAY) TREASURY BILLS
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.

NAREIT-EQUITY INDEX
All of the  data is  based  upon the last  closing  price of the  month  for all
tax-qualified  REITs  listed  on the  NYSE,  AMSE  and the  NASDAQ.  The data is
market-value-weighted.  Prior to 1987 REITs were added to the index the  January
following  their  listing.  Since 1987 Newly formed or listed REITs are added to
the total  shares  outstanding  figure in the month that the shares are  issued.
Only  common  shares  issued by the REIT are  included  in the index.  The total
return  calculation  is based upon the weighing at the  beginning of the period.
Only those REITs listed for the entire period are

upon their payment date. There is no smoothing of income. Liquidating dividends,
whether full or partial, are treated as income.

RUSSELL 2000 SMALL STOCK INDEX
Index of the 2,000 smallest  stocks in the Russell 3000 Index (TM); the smallest
company has a market  capitalization of approximately  $13 million.  The Russell
3000 is comprised of the 3,000  largest US  companies  as  determined  by market
capitalization  representing  approximately  98% of the US  equity  market.  The
largest  company in the index has a market  capitalization  of $67 billion.  The
Russell Indexes (TM) are reconstituted  annually as of June 1st, based on May 31
market capitalization rankings.

WILSHIRE REAL ESTATE SECURITIES INDEX
The Wilshire Real Estate  Securities  Index is a market  capitalization-weighted
index which measures the performance of more than 85 securities.

The index  contains  performance  data on five  major  categories  of  property;
office, retail, industrial, apartment and miscellaneous. Additionally, the Index
has real estate portfolio encumbered by 16% third party mortgages. The companies
in the WRESEC are 79% equity  and hybrid  REIT's and 21% real  estate  operating
companies. The capitalization is 47% NYSE, 33% AMEX and 20% OTC."

STANDARD & POOR'S MIDCAP 400 INDEX
The Standard and Poor's MidCap 400 Index is a  market-value-weighted  index. The
performance  data for the MidCap 400 Index were  calculated by taking the stocks
presently in the MidCap 400 Index and tracking them backwards in time as long as
there were prices reported.  No attempt was made to determine what stocks "might
have  been" in the  MidCap  400  Index  five or ten  years  ago had it  existed.
Dividends  are  reinvested  on a monthly  basis prior to June 30, 1991,  and are
reinvested daily thereafter.

The S&P MidCap 400 Index and the S&P 500 together represent approximately 85% of
the total market capitalization of stocks traded in the United States.

LIPPER BALANCED FUNDS INDEX

Equally-weighted  performance indices,  adjusted for capital gains distributions
and income  dividends of  approximately  30 of the largest  funds with a primary
objective  of  conserving  principal  by  maintaining  at all  times a  balanced
portfolio of stocks and bonds.  Typically,  the  stock/bond  ratio ranges around
60%/40%.

ITEM 26.    NUMBER OF HOLDERS OF SECURITIES

                            Number of Record Holders
   
      Title of Class                               as of December 31, 1997
      --------------                               -----------------------

  Class A Shares of Beneficial Interest                     7,894
  Class B Shares of Beneficial Interest                     5,184

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

                                      C-5
<PAGE>

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

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.       Class Y Shares

         Class Y Shares  are sold at net  asset  value  per  share  without  the
imposition of an initial sales charge.  Class Y Shares are not subject to a CDSC
upon  redemption  regardless of the length of the period of time such shares are
held. Class Y Shares are sold subject to the minimum  purchase  requirements set
forth  in the  Fund's  prospectus.  Class Y  Shares  shall  be  entitled  to the
shareholder  services set forth from time to time in the Fund's  prospectus with
respect to Class Y Shares.  Class Y Shares are not subject to fees payable under
a distribution or other plan adopted to Rule 12b-1.  The Class Y Shareholders of
the Fund have  exclusive  voting  rights,  if any,  with  respect  to the Fund's
possible future  adoption of a Class Y Rule 12b-1  Distribution  Plan.  Transfer
agency fees are allocated to Class Y 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 Y shares  shall
bear the costs and expenses associated with conducting a shareholder meeting for
matters relating to Class Y shares.

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

         Article V.        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

(the "Act")) of (a) all of the Trustees of the Trust, on behalf of the Fund, and
