(1) Purchases of $1,000,000  or more and  purchases by  participants  in certain
group plans are not subject to an initial  sales charge.  A contingent  deferred
sales charge  ("CDSC") of 1% may,  however,  be charged on  redemptions  by such
accounts  of  shares  held  less  than one  year,  as  further  described  under
"Redemptions and Repurchases."
    

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

EXAMPLE:

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

Management Fee       1 Year     3 Years  5 Years  10 Years

  Maximum              $11        $35     $61       $135
  Minimum              $10        $30     $52       $116
    

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

THE EXAMPLE IS  DESIGNED  FOR  INFORMATIONAL  PURPOSES  ONLY,  AND SHOULD NOT BE
CONSIDERED A  REPRESENTATION  OF PAST OR FUTURE EXPENSES OR RETURN.  ACTUAL FUND
EXPENSES AND RETURN VARY FROM YEAR TO YEAR AND MAY BE HIGHER OR LOWER THAN THOSE
SHOWN.

Information.  The  Fund's  payment  of a  12b-1  fee  may  result  in  long-term
shareholders  indirectly paying more than the economic equivalent of the maximum
sales  charge  permitted  under  the  Rules  of Fair  Practice  of the  National
Association of Securities Dealers Inc. ("NASD").

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

III. INVESTMENT OBJECTIVES AND POLICIES

THE  INVESTMENT  OBJECTIVES  OF THE FUND ARE  REASONABLE  INCOME  AND  GROWTH OF
CAPITAL.  The Fund  seeks  these  objectives  by  investing  in a broad  list of
carefully  selected,  reasonably  priced  securities  rather than  investing  in
securities whose prices reflect a premium from their current market  popularity.
Most of the  Fund's  assets  are  invested  in common  stocks  and other  equity
securities  such as  preferred  stocks and  securities  convertible  into common
stock,  but the Fund may also  invest  in debt  securities  and cash  equivalent
investments.

The largest  portions of the Fund's  portfolio are invested in  securities  that
have paid  dividends  within the preceding  twelve months,  but some  non-income
producing securities are held for anticipated  increases in value. Assets of the
Fund are  substantially  fully invested at all times because  management  avoids
speculating on broad changes in the level of the market.

   
Whenever  the Fund  wishes  to  obtain  funds not  otherwise  available  for the
purchase  of an  attractive  security,  it pursues  the  policy of selling  that
security in its portfolio which seems the least  attractive  security owned. The
resulting  rate of turnover of the  portfolio  is not  considered  an  important
factor. See "Financial Highlights" for the Fund's actual turnover rate. The Fund
does  not  purchase  and  sell  securities  for  short-term  profits;   however,
securities  are sold  without  regard to the time  they have been held  whenever
selling seems advisable.
    

The  Fund may  enter  into  repurchase  agreements  with  banks,  generally  not
exceeding seven days. Such  repurchase  agreements will be fully  collateralized
with United States  ("U.S.")  Treasury and/or 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.

The Fund may write (sell) covered call options in standard  contracts  traded on
national securities exchanges or those which may be quoted on the Nasdaq market,
provided  that it continues to own the  securities  covering each call until the
call has been  exercised  or has  expired,  or until  the Fund has  purchased  a
closing call to offset the obligation to deliver  securities for the call it has
written.  The Fund does not expect to write (sell)  covered call options with an
aggregate  market  value  exceeding  5%  of  the  Fund's  total  assets  in  the
foreseeable future. See the Statement of Additional  Information for information
regarding the Fund's ability to write (sell) covered call options.

The Fund may invest in foreign  securities if purchases of such  securities  are
otherwise  consistent with the fundamental  policies of the Fund. As a matter of
practice,  however,  the Fund does not  invest in  foreign  securities  if there
appears  to  be  a  substantial  risk  to  the  issuer  of  such  securities  of
nationalization, confiscation or other national restrictions. In connection with
its  investments  in foreign  securities  and in order to protect itself against
uncertainty in future  exchange rates,  the Fund may engage in foreign  currency
exchange transactions.
<PAGE>

   
The Fund's  fundamental  investment  objectives and the  fundamental  investment
restrictions  set forth in the  Statement of Additional  Information  may not be
changed  without  shareowner   approval.   Certain  other  investment  policies,
strategies and  restrictions  on investment are noted  throughout the Prospectus
and  are  set  forth  in  the   Statement  of  Additional   Information.   These
non-fundamental investment policies,  strategies and restrictions may be changed
at any time by a vote of the Board of Trustees.  Other  investment  policies and
restrictions on investments described in the Statement of Additional Information
include a policy on lending  portfolio  securities,  and a restriction  that the
Fund  will  not  invest  more  than 5% of its  net  assets  in debt  securities,
including convertible securities,  which are rated less than investment grade or
the  equivalent.  Since all investments are subject to inherent market risks and
fluctuations  in value due to earnings,  economic  conditions and other factors,
the Fund,  of course,  cannot  assure  that its  investment  objectives  will be
achieved.
    

IV. MANAGEMENT OF THE FUND

The Fund's  Board of Trustees  has overall  responsibility  for  management  and
supervision of the Fund.  There are currently eight Trustees of the Fund, six of
whom are not  "interested  persons"  of the Fund as  defined  in the  Investment
Company  Act of 1940 (the "1940  Act"),  as  amended.  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 of and general background information
regarding each Trustee and executive officer of the Fund.

The Fund is managed under a 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 Fund's Board of Trustees. PMC is a
wholly-owned   subsidiary  of  The  Pioneer  Group,  Inc.  ("PGI"),  a  Delaware
corporation.  PGI's indirect wholly-owned subsidiary, Pioneer Funds Distributor,
Inc. ("PFD"), is the principal underwriter of shares of the Fund.

Each domestic equity portfolio  managed by PMC,  including the Fund, is overseen
by the Domestic Equity Portfolio Management  Committee,  which consists of PMC's
most senior domestic equity professionals. The Committee is chaired by Mr. David
Tripple,  PMC's  President  and Chief  Investment  Officer  and  Executive  Vice
President  of each of the  Funds.  Mr.  Tripple  joined  PMC in 1974 and has had
general  responsibility  for PMC's investment  operations and specific portfolio
assignments for over five years.  Day-to-day management of the Fund has been the
responsibility  of John A.  Carey,  Vice  President  of the Fund and PMC,  since
February 1987. Mr. Carey joined PMC in 1979.
<PAGE>

   
John F. Cogan,  Jr.,  Chairman and  President of the Fund,  Chairman of PFD, and
President and a Director of PGI and Chairman of PMC, owned  approximately 15% of
the outstanding capital stock of PGI as of January 31, 1996.
    

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.  PMC's and PFD's  executive  offices  are located at 60
State Street, Boston, Massachusetts 02109.

   
   Under the terms of its contract with the Trust, 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 expenses, including 
executive salaries and the rental of certain office space, related 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 Trust 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, 
individual states or blue sky securities agencies, territories and foreign 
countries, including the preparation of Prospectuses and Statements of 
Additional Information for filing with regulatory agencies; (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 
in accordance with Rule 12b-1 promulgated by the SEC pursuant to the 1940 
Act; (j) compensation of those Trustees of the Trust who are not affiliated 
with or interested persons of PMC, the Trust (other than as Trustees), PGI or 
PFD; (k) the cost of preparing and printing share certificates; and (l) 
interest on borrowed money, if any. In addition to the expenses described 
above, the Fund shall pay all brokers' and underwriting commissions 
chargeable to the Fund in connection with securities transactions to which 
the Fund is a party. 
    

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  brokerage  or research  services or sells shares of the
Pioneer mutual funds. See the Statement of Additional  Information for a further
description of PMC's brokerage allocation practices.

   
MANAGEMENT FEE

As  compensation  for its  management  services and certain  expenses  which PMC
incurs  on  behalf  of the  Fund,  the Fund  pays PMC a  management  fee that is
comprised of two  components.  The first component is a basic fee equal to 0.60%
per annum of the Fund's  average daily net assets (the "Basic Fee").  The second
component is a performance fee adjustment.

COMPUTING THE PERFORMANCE FEE ADJUSTMENT.  The Basic Fee is subject to an upward
or downward adjustment, depending on whether, and to what extent, the investment
performance of 

<PAGE>

the Fund for the performance  period  exceeds,  or is exceeded by, the record of
the index  determined by the Fund to be  appropriate  over the same period.  The
Trustees have  designated the Lipper Growth and Income Funds Index (the "Index")
for this purpose.  The Index represents the arithmetic mean  performance  (i.e.,
equally  weighted)  of the  thirty  largest  funds  with  a  growth  and  income
investment objective.

The  performance  period  consists of the current  month and the prior 35 months
("performance  period"). Each percentage point of difference (up to a maximum of
+/-10) is  multiplied  by a  performance  adjustment  rate of 0.01%.  Thus,  the
maximum annualized adjustment rate is +/-0.10%.  This performance  comparison is
made at the end of each month.  An  appropriate  percentage  of this rate (based
upon the number of days in the current month) is then  mutliptlied by the Fund's
average net assets for the entire  performance  period,  giving a dollar  amount
that will be added to (or subtracted from) the Basic Fee.

The Fund's performance is calculated based on its net asset value per share. For
purposes of calculating  the  performance  adjustment,  any dividends or capital
gains distributions paid by the Fund are treated as if reinvested in Fund shares
at the net asset value per share as of the record date for  payment.  The record
for the  Index  is  based  on  change  in  value  and is  adjusted  for any cash
distributions from the companies whose securities comprise the Index.

Because the adjustment to the Basic Fee is based on the comparative  performance
of the Fund and the record of the Index,  the controlling  factor is not whether
Fund  performance  is up or down, but whether it is up or down more or less than
the record of the Index. Moreover, the comparative investment record of the Fund
is based  solely  on the  relevant  performance  period  without  regard  to the
cumulative performance over a longer or shorter period of time.

From time to time, the Trustees may determine that another securities index is a
more  appropriate  benchmark  than the  Index for  purposes  of  evaluating  the
perfromance of the Fund. In such event, a successor index may be substituted for
the Index.  However,  the  calculation  of the  performance  adjustment  for any
portion of the  performance  period prior to the adoption of the seccessor index
would still be based upon the Fund's performance compared to the Index.

The Fund's current  management  contract with PMC became  effective May 1, 1996.
Under  the  terms of the  contract,  beginning  on May 1, 1996 the Fund will pay
management fees at a rate equal to the Basic Fee plus or minus the amount of the
performance adjustment for the current month and the preceding 35 months. At the
end of each succeeding month, the performance period will roll forward one month
so that it is always a 36-month  period  consisting of the current month and the
prior 35 months as described above. If including the intial rolling  performance
period  (that  is,  the  period  prior to the  effectiveness  of the  management
contract),  has the  effect of  increasing  the Basic  Fee for any  month,  such
aggreagte  prior  results  will be  

<PAGE>

treated as Index neutral for purposes of calculating the performance  adjustment
for such month. Otherwise,  the performance adjustment will be made as described
above.

The Basic Fee is computed  daily,  the  performance fee adjustment is calculated
once per month and the entire management fee is normally paid monthly.

Until May1,  1996,  as  compensation  for its  management  services  and certain
expenses which PMC incured,  PMC was entitled to a management fee equal to 0.50%
per annum of the Fund's  average daily net assets up to $250  million,  0.48% of
the next $50  million  and 0.45% of the excess  over $300  million.  The fee was
normally computed daily and paid monthly.  During the fiscal year ended December
31, 1995, the Fund incurred  expenses of approximately  $, including  management
fees paid or payable to PMC of approximately $.
    


V. DISTRIBUTION PLAN

The Fund has adopted a Plan of Distribution (the "Plan") in accordance with Rule
12b-1 under the 1940 Act pursuant to which certain distribution fees are paid to
PFD.  As  required  by Rule  12b-1,  the Plan was  approved by a majority of the
outstanding  shares held by the  shareholders  of the Fund and by the  Trustees,
including a majority of the  Trustees  who are not  "interested  persons" of the
Fund.

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

Expenditures  of the Fund  pursuant  to the Plan are  accrued  daily and may not
exceed  0.25% of average  daily net  assets.  Distribution  expenses  of PFD are
expected to  substantially  exceed the  distribution  fees paid by the Fund in a
given year. The Plan does not provide for the carryover of reimbursable expenses
beyond 12 months from the time the Fund is first  invoiced  for an expense. 

<PAGE>

The limited carryover provision in the Plan may result in an expense invoiced to
the Fund in one fiscal  year being paid in the  subsequent  fiscal year and thus
being treated for purposes of calculating  the maximum  expenditures of the Fund
as  having  been  incurred  in the  subsequent  fiscal  year.  In the  event  of
termination or  non-continuance of the Plan, the Fund has 12 months to reimburse
any  expense  which it  incurs  prior to such  termination  or  non-continuance,
provided that payments by the Fund during such 12-month  period shall not exceed
0.25% of the Fund's  average net daily assets  during such period.  The Plan may
not be amended  to  increase  materially  the annual  percentage  limitation  of
average net assets which may be spent for the services described therein without
approval of the shareholders of the Fund.

VI. INFORMATION ABOUT FUND SHARES

HOW TO PURCHASE SHARES

   
         YOU MAY BUY FUND SHARES FROM ANY SECURITIES  BROKER-DEALER  WHICH HAS A
SALES AGREEMENT WITH PFD. IF YOU DO NOT HAVE A SECURITIES BROKER-DEALER,  PLEASE
CALL 1-800-225-6292. SHARES WILL BE PURCHASED AT THE PUBLIC OFFERING PRICE, THAT
IS,  THE NET ASSET  VALUE PER  SHARE  PLUS ANY  APPLICABLE  SALES  CHARGE,  NEXT
COMPUTED  AFTER  RECEIPT OF A PURCHASE  ORDER,  EXCEPT AS SET FORTH  BELOW.  THE
MINIMUM INITIAL  INVESTMENT IS $50.  Separate  minimum  investment  requirements
apply  to  retirement   plans  and  to  telephone  and  wire  orders  placed  by
broker-dealers;  no sales charge or minimum investment requirements apply to the
reinvestment of dividends or capital gains distributions.
    

The Fund has a minimum account requirement of $500. As a new purchaser, you will
be given at least 24 months from your initial  purchase to increase the value of
the account to $500. See "Redemptions and Repurchases."

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

YOU ARE STRONGLY  URGED TO CONSULT WITH YOUR FINANCIAL  REPRESENTATIVE  PRIOR TO
REQUESTING  A TELEPHONE  PURCHASE.  To purchase  shares by  telephone,  you must
establish your bank account of record by completing the  appropriate  section of
your Account  Application or an Account  Options Form.  PSC will  electronically
debit  the  amount  of each  purchase  from this  pre-designated  bank

<PAGE>

account. Telephone purchases may not be made for 30 days after the establishment
of your bank of record or any change to your bank information.

   
Telephone  purchases  will be priced at the net asset value plus any  applicable
sales  charge  next  determined  after  PSC's  receipt of a  telephone  purchase
instruction  and receipt of good funds  (usually  three days after the  purchase
instruction).  You may always  elect to deliver  purchases  to PSC by mail.  See
"Telephone Transactions and Related Liabilities" for additional information.
    

The public  offering  price is the net asset value per share next computed after
receipt of a purchase order, plus a sales charge as follows:

                                                          DEALER
                               SALES CHARGE AS % OF      ALLOWANCE

  $100,000                   4.50          4.71            4.00
$100,000 but less
  than $250,000              3.50          3.63            3.00
$250,000 but less
  than $500,000              2.50          2.56            2.00
$500,000 but less
  than $1,000,000            2.00          2.04            1.75
$1,000,000 or more           -0-           -0-           see below

   
No sales charge is payable at the time of purchase on  investments of $1,000,000
or more or on purchases by certain  group plans  ("Group  Plans"),  but for such
investments  a  CDSC  of 1% is  imposed  in  the  event  of  certain  redemption
transactions  within one year of purchase.  See  "Redemptions  and  Repurchases"
below.  PFD may, in its  discretion,  pay a  commission  to  broker-dealers  who
initiate and are responsible  for such purchases as follows:  1% on the first $5
million  invested;  0.50% on the next $45 million;  and 0.25% on the excess over
$50 million.  These  commissions will not be paid if the purchaser is affiliated
with the  broker-dealer  or if the purchase  represents  the  reinvestment  of a
redemption made during the previous twelve calendar months.  Broker-dealers  who
receive a commission in connection  with  purchases at net asset value by 401(a)
or 401(k)  retirement plans with 1,000 or more eligible  participants or with at
least $10 million in plan assets will be required to return any commission  paid
or a pro rata portion  thereof if the retirement  plan redeems its shares within
12 months of purchase.  See also  "Redemptions  and  Repurchases." In connection
with PGI's acquisition of Mutual of Omaha Fund Management Company and contingent
upon the achievement of certain sales objectives, PFD 

<PAGE>

may pay to Mutual of Omaha Investor Services, Inc. 50% of PFD's retention of any
sales commission on sales of the Fund's shares through such dealer.  Shares sold
outside  the  U.S.  to  persons  who are not U.S.  citizens  may be  subject  to
different  sales  charges,   CDSCs  and  dealer  compensation   arrangements  in
accordance with local laws and business practices.
    

The schedule of sales  charges above is applicable to purchases of shares of the
Fund by (i) an individual,  (ii) an  individual,  his or her spouse and children
under the age of 21 and (iii) a trustee or other  fiduciary of a trust estate or
fiduciary   account   or  related   trusts  or   accounts   including   pension,
profit-sharing  and other employee benefit trusts qualified under Section 401 or
408 of the Internal Revenue Code of 1986, as amended (the "Code"), although more
than one beneficiary is involved.

The sales  charge  applicable  to a current  purchase of shares of the Fund by a
person  listed above is determined by adding the value of shares to be purchased
to the aggregate value (at current offering price) of shares of any of the other
Pioneer  mutual  funds  previously  purchased  and then owned,  provided  PFD is
notified by such person or his or her broker-dealer each time a purchase is made
which would qualify. Pioneer mutual funds include all mutual funds for which PFD
serves as principal  underwriter.  For example, a person investing $5,000 in the
Fund who  currently  owns shares of other  Pioneer  mutual funds with a value of
$45,000  would  pay a sales  charge  of 4.50% of the  offering  price of the new
investment.

Sales  charges may also be reduced  through an agreement to purchase a specified
quantity of shares over a designated  13-month  period by completing the "Letter
of Intention" section of the Account  Application.  Information about the Letter
of  Intention  procedure,  including  its terms,  is  contained  in the  Account
Application as well as in the Statement of Additional Information.

   
Shares  of the Fund may be sold at a  reduced  or  eliminated  sales  charge  to
certain Group Plans under which a sponsoring  organization makes recommendations
to, permits group  solicitation of, or otherwise  facilitates  purchases by, its
employees,  members  or  participants.  Shares of the Fund may be sold to 401(k)
retirement  plans with 100 or more  participants  or at least  $500,000  in plan
assets.  Shares of the Fund may be sold at net asset  value per share  without a
sales charge to Optional Retirement Program (the "Program")  participants if (i)
the employer has authorized a limited number of investment company providers for
the Program, (ii) all authorized investment company providers offer their shares
to Program  participants  at net asset  value,  (iii) the employer has agreed in
writing to  actively  promote the  authorized  investment  providers  to Program
participants and (iv) the Program provides for a matching  contribution for each
participant contribution.  Information about such arrangements is available from
PFD.
    

Shares of the Fund may also be sold at net asset value per share without a sales
charge to: (a) current or former  Trustees and officers of the Fund and partners
and employees of its legal counsel;  (b) current or former directors,  officers,
employees or sales  representatives  of PGI or its 

<PAGE>

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

Investors who are clients of a broker-dealer with a current sales agreement with
PFD may purchase shares of the Fund at net asset value,  without a sales charge,
to the extent that the purchase  price is paid out of proceeds  from one or more
redemptions  by the investor of shares of certain other mutual  funds.  In order
for a purchase to qualify for this privilege,  the investor must document to the
broker-dealer that the redemption occurred within 60 days immediately  preceding
the  purchase of shares of the Fund;  that the client paid a sales charge on the
original purchase of the shares redeemed;  and that the mutual fund whose shares
were redeemed also offers net asset value purchases to redeeming shareholders of
any of the Pioneer mutual funds. Further details may be obtained from PFD.

NET ASSET VALUE AND PRICING OF ORDERS

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

Securities are valued at the last sale price on the principal exchange or market
where they are traded. Securities which have not traded on the date of valuation
or securities  for which sales prices are not  generally  reported are valued at
the mean between the current bid and asked prices.  Securities quoted in foreign
currencies  are  converted to U.S.  dollars  utilizing  foreign  exchange  rates
employed  by the Fund's  independent  pricing  services.  Generally,  trading in
foreign securities is substantially completed each day at various times prior to
the close of regular trading on the Exchange. The values of such securities used
in computing the net asset value of the

<PAGE>

Fund's shares are determined as of such times.  Foreign currency  exchange rates
are also  generally  determined  prior to the close of  regular  trading  on 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 regular trading on the Exchange and will therefore not be reflected
in the computation of the Fund's net asset value. If events materially affecting
the value of such securities occur during such period, then these securities are
valued at their fair value as  determined  in good  faith by the  Trustees.  All
assets  of the Fund for  which  there is no other  readily  available  valuation
method  are  valued  at their  fair  value as  determined  in good  faith by the
Trustees.

An order for shares  received by a  broker-dealer  prior to the close of regular
trading on the Exchange  (currently 4:00 p.m.  Eastern Time) is confirmed at the
redemption  price  determined at the close of regular trading on the Exchange on
the day the order is  received,  provided  the order is received by PFD prior to
PFD's  close  of  business   (usually  5:30  p.m.   Eastern  Time).  It  is  the
responsibility  of  broker-dealers  to  transmit  orders  so that  they  will be
received  by PFD  prior  to PFD's  close of  business.  An order  received  by a
broker-dealer  following  the close of regular  trading on the Exchange  will be
confirmed  at the  offering  price as of the  close of  regular  trading  on the
Exchange on the next trading day.

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.

DIVIDENDS, DISTRIBUTIONS AND TAXATION

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

Under the Code,  the Fund will be subject to a  nondeductible  4% federal excise
tax on a portion of its  undistributed  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, in
December.  Distributions  from net short-term capital gains, if any, may be paid
with such dividends,  and other  distributions  from income and/or capital gains
may also be made at such other times as may be necessary to avoid federal income
or excise tax.  Dividends from the Fund's net investment  income, net short-term
capital  gains and

<PAGE>

certain net foreign  exchange  gains are taxable as ordinary  income.  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 DISTRIBUTIONS 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 DISTRIBUTIONS WILL BE PROVIDED
TO SHAREHOLDERS  ANNUALLY.  For further information on the distribution  options
available to shareholders,  see "Distribution  Options" and "Directed Dividends"
below.

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

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 such backup  withholding  or if the Fund  receives  notice from the  Internal
Revenue Service ("IRS") or a broker that such withholding applies.  Please refer
to the Account Application for additional information.

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

REDEMPTIONS AND REPURCHASES

   
REDEMPTIONS BY MAIL. As a  shareholder,  you have the right to offer your shares
for  redemption by delivering to PSC a written  request for redemption in proper
form,  signed by all registered  owners,  and your share  certificates,  if any,
properly  endorsed and in good order for transfer.  Redemptions  will be made in
cash at the net asset value per share next determined  following receipt in good
order by PSC of all  necessary  documents  subject in certain  cases to the CDSC
described below.
    

Good order  means  that  there are no  outstanding  claims or  requests  to hold
redemptions on the account, any certificates are endorsed by the record owner(s)
exactly as the shares are registered and the  signature(s) are guaranteed by any
of the following  eligible  guarantor  institutions:  (i) all 

<PAGE>

brokers,  dealers,  municipal  securities  dealers and/or brokers and government
securities  dealers and/or brokers who are members of a clearing agency or whose
net capital exceeds $100,000;  (ii) all banks; (iii) all credit unions; (iv) all
savings  associations,  including  all  savings and loan  associations;  (v) all
national  securities  exchanges,  registered  securities  associations,  and all
clearing  agencies;  and (vi) all trust  companies.  In addition,  in some cases
(involving  fiduciary  or  corporate  transactions),  good order may require the
furnishing of additional documents.

Signature  guarantees may be waived for redemption  requests of $50,000 or less,
provided  that the record holder  executes the  redemption  request,  payment is
directed to the record holder at the address of record,  and the address has not
changed in the  previous 30 days.  You cannot  provide a signature  guarantee by
facsimile ("fax"). Payment normally will be made within seven days after receipt
of these documents. The Fund reserves the right to withhold payment until checks
received in payment of shares  purchased  have cleared,  which may take up to 15
calendar  days from the purchase  date.  For  additional  information  about the
necessary documentation for redemption by mail, call PSC at 1-800-225-6292.

REDEMPTION BY TELEPHONE OR FAX. Your account is automatically authorized to have
the  telephone  redemption  privilege  unless you  indicated  otherwise  on your
Account Application or by writing to PSC. Proper account  identification will be
required for each telephone  redemption.  The telephone redemption option is not
available to retirement  plan accounts.  A maximum of $50,000 may be redeemed by
telephone  or fax and the  proceeds  may be received by check or by bank wire or
electronic  funds transfer.  To receive the proceeds by check: the check must be
made payable  exactly as the account is registered and the check must be sent to
the  address  of record  which  must not have  changed  in the last 30 days.  To
receive the proceeds by bank wire or by electronic funds transfer:  the proceeds
must be sent to your bank  address  of  record  which  must  have been  properly
pre-designated  either on your Account Application or on an Account Options Form
and which must not have changed in the last 30 days. To redeem by fax, send your
redemption request to 1-800-225-4240. You may always elect to deliver redemption
instructions   to  PSC  by  mail.  See  "Telephone   Transactions   and  Related
Liabilities" below. Telephone redemptions will be priced as described above. YOU
ARE  STRONGLY  URGED TO  CONSULT  WITH YOUR  FINANCIAL  REPRESENTATIVE  PRIOR TO
REQUESTING A TELEPHONE REDEMPTION.

SALES OF SHARES THROUGH BROKER-DEALERS. For the convenience of shareholders, the
Fund has  authorized  PFD to act as its agent in the repurchase of shares of the
Fund from  qualified  broker-dealers.  The Fund  reserves the right to terminate
this  procedure  at  any  time.  Offers  to  sell  shares  to  the  Fund  may be
communicated to PFD by wire or telephone by broker-dealers  for their customers.
The Fund's practice will be to repurchase  shares offered to it at the net asset
value per share  determined  as of the close of business of the  Exchange on the
day the offer for  repurchase is received and accepted by the  broker-dealer  if
the offer is received by PFD before the close of business on that day.
<PAGE>

A  broker-dealer  which receives an offer for repurchase is responsible  for the
prompt transmittal of such offer to PFD. Payment of the repurchase proceeds will
be made in cash to the broker-dealer placing the order. Except for certain large
accounts  subject  to a CDSC  (as  described  below),  neither  the Fund nor PFD
charges any fee or commission upon such  repurchase  which is then settled as an
ordinary  transaction with the  broker-dealer  (which may charge the shareholder
for this service) delivering the shares repurchased. Payment will be made within
seven  days of the  receipt  by PSC of  valid  instructions,  including  validly
endorsed certificates, if appropriate, in good order as described above.

ADDITIONAL CONDITIONS OF REDEMPTION. 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  upon  the  market  value of the  portfolio  at the time of
redemption or repurchase.  Redemptions and repurchases are taxable  transactions
to  shareholders.  Shareholders  whose  accounts are registered in the name of a
broker,  dealer or other financial  institution must contact a representative of
the institution holding the shares to arrange for a redemption.

Redemptions may be suspended or payment postponed during any period in which any
of the  following  conditions  exists:  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.

Purchases of $1,000,000 or more, and purchases by  participants  in a Group Plan
which  have not been  subject to a sales  charge,  may be subject to a CDSC upon
redemption or repurchase. A CDSC is payable on these investments in the event of
a share redemption within 12 months following the share purchase, at the rate of
1% of the lesser of the value of the shares  redeemed  (exclusive  of reinvested
dividend and capital gain  distributions)  or the total cost of such shares.  In
determining whether a CDSC is payable, and, if so, the amount of the CDSC, it is
assumed  that  shares  purchased  with  reinvested  dividend  and  capital  gain
distributions  and then such other shares which are held the longest will be the
first  redeemed.  Shares  subject to the CDSC which are  exchanged  into another
Pioneer  mutual fund will  continue to be subject to the CDSC until the original
12-month period expires. See "Exchange Privilege" for more information. However,
no CDSC is  payable  with  respect  to  purchases  of shares by 401(a) or 401(k)
retirement  plans with 1,000 or more eligible  participants or with at least $10
million in plan assets.

WAIVER OR REDUCTION OF  CONTINGENT  DEFERRED  SALES  CHARGE.  The CDSC on shares
subject to a CDSC may be waived or reduced for  non-retirement  accounts if: (a)
the redemption results from the death of all registered owners of an account (in
the case of UGMAs,  UTMAs and trust  accounts,  waiver applies upon the death of
all  beneficial  owners)  or a total and  permanent  disability  (as  defined in
Section 72 of the Code) of all registered owners occurring after the purchase of
the shares  being  redeemed or (b) the  redemption  is made in  connection  with
limited 

<PAGE>

automatic redemptions as set forth in "Systematic  Withdrawal Plans" (limited in
any  year  to 10% of the  value  of the  account  in the  Fund at the  time  the
withdrawal plan is established).

The CDSC on shares  subject  to a CDSC may be waived or reduced  for  retirement
plan  accounts  if:  (a) the  redemption  results  from the death or a total and
permanent  disability (as defined in Section 72 of the Code) occurring after the
purchase of the shares being  redeemed of a  shareholder  or  participant  in an
employer-sponsored  retirement plan; (b) the distribution is to a participant in
an IRA,  403(b) or  employer-sponsored  retirement  plan, is part of a series of
substantially equal payments made over the life expectancy of the participant or
the joint life  expectancy of the  participant  and his or her beneficiary or as
scheduled periodic payments to a participant  (limited in any year to 10% of the
value  of the  participant's  account  at the time the  distribution  amount  is
established; a required minimum distribution due to the participant's attainment
of age 70-1/2 may exceed the 10% limit only if the distribution  amount is based
on plan assets held by Pioneer); (c) the distribution is from a 401(a) or 401(k)
retirement  plan  and is a return  of  excess  employee  deferrals  or  employee
contributions  or a qualifying  hardship  distribution as defined by the Code or
results from a termination of employment  (limited with respect to a termination
to 10% per year of the value of the plan's assets in the Fund as of the later of
the prior December 31 or the date the account was established  unless the plan's
assets are being rolled over to or  reinvested  in the same class of shares of a
Pioneer mutual fund subject to the CDSC of the shares  originally held); (d) the
distribution is from an IRA, 403(b) or employer-sponsored retirement plan and is
to be  rolled  over to or  reinvested  in the same  class of shares in a Pioneer
mutual fund and which will be subject to the  applicable  CDSC upon  redemption;
(e) the  distribution  is in the form of a loan to a participant in a plan which
permits loans (each  repayment of the loan will constitute a new sale which will
be subject to the applicable CDSC upon  redemption);  or (f) the distribution is
from a  qualified  defined  contribution  plan and  represents  a  participant's
directed transfer (provided that this privilege has been pre-authorized  through
a prior agreement with PFD regarding participant directed transfers).

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

REDEMPTION OF SMALL ACCOUNTS

As a new shareholder,  you have a minimum of 24 months (including the six months
following  the mailing of the notice  described  below) to increase the value of
your account to $500 or more.  If you hold shares of the Fund in an account with
a net asset value of less than $500 due to  redemptions  or exchanges or failure
to meet the initial  minimum account  requirement set forth 

<PAGE>

above, the Fund may redeem the shares held in this account at net asset value if
you have not  increased  the net asset  value of the  account  to at least  $500
within six months of written  notice by the Fund to you of the Fund's  intention
to redeem the shares.

DESCRIPTION OF SHARES AND VOTING RIGHTS

   
The Fund is a  diversified  open-end  management  investment  company  (commonly
referred  to as a mutual  fund)  which was  originally  organized  as a Delaware
corporation in 1928 and reorganized as a Massachusetts corporation in 1967, as a
Massachusetts  business trust in 1985 and as a Delaware business trust on May 1,
1996.  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.  See
"Redemptions and Repurchases". The Fund is not required, and does not intend, to
hold annual shareowner  meetings although special meetings may be called for the
purpose of  electing  or  removing  Trustees,  changing  fundamental  investment
restrictions or approving a management contract.
    

The Fund reserves the right to create and issue additional  series of shares, in
which case the shares of each series would participate  equally in the earnings,
dividends and assets of the  particular  series.  Shares of each series would be
entitled to vote separately to approve investment advisory agreements or changes
in investment  restrictions,  but shares of all series would be entitled to vote
together in the election or selection of Trustees and accountants.

   
The  Trustees  have the  authority,  without  further  shareowner  approval,  to
classify and reclassify the shares of the Fund, or any additional  series of the
Fund, into one or more classes. As of the date of this Prospectus,  the Trustees
have  authorized  the issuance of only one class of shares,  entitled  shares of
beneficial  interest.  Each share represents an equal proportionate  interest in
the Fund with each other share.  Shareholders  are entitled to one vote for each
share held and may vote in the  election  and removal of  Trustees  and on other
matters  submitted to  shareholders.  Shares have no  preemptive  or  conversion
rights.

In addition to the  requirements  under  Delaware law, the  Declaration of Trust
provides that a shareowner  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  shareowner  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.
<PAGE>

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.  Upon liquidation of the Fund, the Fund's  shareholders would be
entitled to share pro rata in the Fund's net assets available for  distribution.
Shares will remain on deposit with the Fund's  transfer  agent and  certificates
will not  normally be issued.  Certificates  for  fractional  shares will not be
issued.  The Fund  reserves  the  right  to  charge  a fee for the  issuance  of
certificates.
    


VII. 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 Shareholder  Services,  Pioneering Services Corporation,
P.O. Box 9014, Boston,  Massachusetts 02205-9014.  Brown Brothers Harriman & Co.
("the Custodian")  serves as custodian of the Fund's portfolio  securities.  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,  except
Automatic  Investment  Plan  transactions  which are  confirmed  quarterly.  The
Pioneer  Combined  Account  Statement,  mailed  quarterly,  is  available to all
shareholders who have more than one Pioneer account.

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

ADDITIONAL INVESTMENTS

You may add to your  account by sending a check ($50  minimum)  to PSC  (account
number  should be  clearly  indicated).  The bottom  portion  of a  confirmation
statement  may be used as a  remittance  slip  to make  additional  investments.
Additions to your  account,  whether by check or through a Pioneer  Investomatic
Plan, are invested in full and  fractional  shares of the Fund at the

<PAGE>

applicable  offering  price in effect as of the close of regular  trading on the
Exchange on the day of receipt.

AUTOMATIC INVESTMENT PLANS

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

FINANCIAL REPORTS AND TAX INFORMATION

As a shareholder, you will receive financial reports at least semi-annually.  In
January of each year, the Fund will mail you information about the tax status of
dividends and other 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  available  options  are (a)  dividends  in cash  and  capital  gains
distributions in additional  shares;  and (b) all dividends and distributions in
cash. These two options are not available,  however,  for retirement plans or an
account  with a net asset value of less than $500.  Changes in the  distribution
options may be made by written request to PSC.

DIRECTED DIVIDENDS

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

DIRECT DEPOSIT

If you have elected to take  distributions,  whether  dividends or dividends and
capital gains, in cash, or have  established a Systematic  Withdrawal  Plan, you
may choose to have those cash 

<PAGE>

payments deposited directly into your savings, checking or NOW bank account. You
may establish this service by completing the appropriate  section on the Account
Application  when  opening a new  account  or the  Account  Options  Form for an
existing account.

VOLUNTARY TAX WITHHOLDING

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

EXCHANGE PRIVILEGE

Exchanges  must be at least $1,000.  You may exchange your shares of the Fund at
net asset value,  without a sales  charge,  for shares of other  Pioneer  mutual
funds which do not offer  different  classes of shares or for the Class A shares
of those  Pioneer  mutual funds that offer more than one class of shares.  There
are  currently  no fees or sales  charges on such an  exchange.  An  exchange of
shares may be made only in states where legally permitted.

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 proper form.

WRITTEN EXCHANGES.  If the exchange request is in writing,  it must be signed by
all record  owner(s)  exactly as the shares  are  registered.  If your  original
account  includes a Pioneer  Investomatic or Systematic  Withdrawal Plan and you
open a new account by  exchange,  you should  specify  whether the plans  should
continue in your new account or remain with your original account.

   
TELEPHONE  EXCHANGES.  Your  account  is  automatically  authorized  to have the
telephone  exchange  privilege  unless you  indicated  otherwise on your Account
Application or by writing to PSC. Proper account identification will be required
for each telephone  exchange.  Telephone  exchanges may not exceed  $500,000 per
account  per  day.  Each  telephone  exchange  request,  whether  by voice or by
FactFoneSM,  will be  recorded.  YOU ARE  STRONGLY  URGED TO  CONSULT  WITH YOUR
FINANCIAL   REPRESENTATIVE  PRIOR  TO  REQUESTING  A  TELEPHONE  EXCHANGE.   See
"Telephone Transactions and Related Liabilities" below.
    

AUTOMATIC  EXCHANGE.  You may  automatically  exchange  shares  from one Pioneer
mutual  fund  account  to  another  Pioneer  mutual  fund  account  on a regular
schedule,  either  monthly  or  quarterly.  The  accounts  must  have  identical
registrations and the originating account must have a minimum balance of $5,000.
The exchange will occur on the 18th day of each month.
<PAGE>

If an exchange  request is received  by PSC before  4:00 p.m.  Eastern  Time (or
before the time that the  Exchange  closes for  regular  trading on that day, if
different), the exchange will be effective on that day if the requirements above
have been met. If the exchange request is received after this time, the exchange
will be effective on the following business day.

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 federal and  (generally)  state income tax purposes,  an exchange
represents  a sale of the shares  exchanged  and a purchase of shares in another
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.

   
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 TRANSACTIONS AND RELATED LIABILITIES

Your  account  is  automatically   authorized  to  have  telephone   transaction
privileges  unless you  indicated  otherwise on your Account  Application  or by
writing to PSC. You may purchase, sell or exchange Fund shares by telephone. See
"Net Asset  Value and  Pricing of Orders"  for more  information.  For  personal
assistance,  call 1-800-225-6292 between 8:00 a.m. and 9:00 p.m. Eastern Time on
weekdays.  Computer-assisted  transactions  may be available to shareholders who
have  pre-recorded  certain  bank  information  (see  "FactFone(SM)").  YOU  ARE
STRONGLY URGED TO CONSULT WITH YOUR FINANCIAL REPRESENTATIVE PRIOR TO REQUESTING
ANY  TELEPHONE  TRANSACTION.  See "Net  Asset  Value  and  Pricing  of  Orders,"
"Redemptions and Repurchases" and "Exchange Privilege" for more information.  To
confirm that each transaction  instruction received by telephone is genuine, PSC
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.  The Fund may implement other procedures from time to time. In all
other  cases,  neither  the 

<PAGE>

Fund,  PSC or 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.
    

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.

FACTFONE SM

   
FactFone SM is an automated inquiry and telephone  transaction  system available
to Pioneer  shareholders  by dialing  1-800-225-4321.  FactFone SM allows you to
obtain  current  information on your Pioneer mutual fund accounts and to inquire
about the prices and yields of all publicly  available  Pioneer mutual funds. In
addition, you may use FactFone SM to make computer-assisted telephone purchases,
exchanges and redemptions  from your Pioneer accounts if you have activated your
PIN.  Telephone  purchases and redemptions  require the  establishment of a bank
account  of  record.  YOU ARE  STRONGLY  URGED TO  CONSULT  WITH YOUR  FINANCIAL
REPRESENTATIVE PRIOR TO REQUESTING ANY TELEPHONE TRANSACTION. Shareholders whose
accounts are registered in the name of a broker-dealer  or other third party may
not be able to use FactFone  SM. See "How to Purchase  Fund  Shares,"  "Exchange
Privilege,"  "Redemptions  and  Repurchases"  and  "Telephone  Transactions  and
Related Liabilities." Call PSC for assistance.
    

TELECOMMUNICATIONS DEVICE FOR THE DEAF (TDD)

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

RETIREMENT PLANS

You should contact the Retirement Plans Department of PSC at 1-800-622-0176  for
information on retirement  plans for businesses,  Simplified  Employee  Pensions
Plans,  IRAs,  and Section  403(b)  retirement  plans for  employees  of certain
non-profit  organizations and public school systems,  all of which are available
in  conjunction   with   investments  in  the  Fund.  The  Account   Application
accompanying this Prospectus should not be used to establish any of these plans.
Separate applications are required.

SYSTEMATIC WITHDRAWAL PLANS

If your  account  has a total  value of at least  $10,000,  you may  establish a
Systematic  Withdrawal  Plan  ("SWP")  providing  for fixed  payments at regular
intervals.  Periodic  checks  of $50 or more  

<PAGE>

will be sent to you monthly or quarterly and your periodic redemptions of shares
may be taxable to you.  You may also  direct that  withdrawal  checks be paid to
another person, although if you make this designation after you have opened your
account, a signature  guarantee must accompany your  instructions.  Purchases of
shares  of the Fund at a time when you have a SWP in  effect  may  result in the
payment of unnecessary sales charges and may therefore be disadvantageous.

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

REINSTATEMENT PRIVILEGE

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

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

THE OPTIONS AND SERVICES  AVAILABLE TO SHAREHOLDERS,  INCLUDING THE TERMS OF THE
EXCHANGE PRIVILEGE AND THE PIONEER INVESTOMATIC PLAN, MAY BE REVISED, SUSPENDED,
OR TERMINATED AT ANY TIME BY PFD OR BY THE FUND.  YOU MAY ESTABLISH THE SERVICES
DESCRIBED IN THIS SECTION WHEN YOU OPEN YOUR ACCOUNT.  YOU MAY ALSO ESTABLISH OR
REVISE  MANY OF THEM ON AN EXISTING  ACCOUNT BY FILLING  OUT AN ACCOUNT  OPTIONS
FORM, WHICH YOU MAY REQUEST BY CALLING 1-800-225-6292.

VIII. INVESTMENT RESULTS

The Fund may include in  advertisements,  and furnish to existing or prospective
shareholders,  information  concerning  the average  annual  total  return on an
investment  in  the  Fund  for  a  designated  period  of  time.  Whenever  this
information  is  provided,  it includes a  standardized  calculation  of average
annual total return computed by determining  the average annual  compounded rate
of return that would cause a  hypothetical  investment  (after  deduction of the
maximum sales charge) made on the first day of the designated  period  (assuming
all dividends 

<PAGE>

and distributions are reinvested) to equal the resulting net asset value of such
hypothetical  investment on the last day of the designated  period.  The periods
illustrated would normally include one, five and ten years.  These  standardized
calculations do not reflect the impact of federal or state income taxes.

The  foregoing  computation  method  is  prescribed  for  advertising  and other
communications subject to SEC Rule 482.  Communications not subject to this rule
may contain one or more additional measures of investment  results,  computation
methods 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. These data may cover any period of the Fund's existence and may or may not
include the impact of sales charges, taxes or other factors.

Other   investments  or  savings   vehicles  and/or  unmanaged  market  indexes,
indicators  of economic  activity,  or averages of mutual  funds  results may be
cited or compared with the investment results of the Fund.  Rankings or listings
by magazines, newspapers or independent statistical or ratings services, such as
Lipper Analytical Services, Inc. or Ibbotson Associates, may also be referenced.

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.  Therefore,  any prior  investment  results of the Fund  should not be
considered  representative  of what an  investment  in the  Fund may earn in any
future  period.  These factors and possible  differences  in the methods used in
calculating  investment results should be considered when comparing  performance
information  regarding the Fund to  information  published for other  investment
companies,  investment  vehicles,  and unmanaged indexes.  The Fund's investment
results  should also be  considered  relative to the risks  associated  with the
Fund's investment objectives and policies.

For further  information  about the  calculation  methods used for computing the
Fund's investment results, see the Statement of Additional Information.

<PAGE>


1.  INVESTMENT POLICIES AND RESTRICTIONS

   
The  Fund's  current  prospectus  (the  "Prospectus")  presents  the  investment
objective  and  the  principal  investment  policies  of  the  Fund.  Additional
investment  policies and a further description of some of the policies described
in the Prospectus appear below.

The  following  policies  and  restrictions  supplement  those  discussed in the
Prospectus.  Whenever  an  investment  policy  or  restriction  states a maximum
percentage of the Fund's assets that may be invested in any security or presents
a policy regarding quality standards,  this standard or other restrictions shall
be  determined  immediately  after  and as a result  of the  Fund's  investment.
Accordingly,  any later increase or decrease  resulting from a change in values,
net assets or other  circumstances will not be considered in determining whether
the investment complies with the Fund's investment objectives and policies.
    

         Lending of Portfolio Securities

         In order to realize  additional income, the Fund may lend its portfolio
securities, principally to broker-dealers,  under agreements which would require
that the loans be secured  continuously  by cash  equivalents  or United  States
("U.S.")  Treasury  bills equal at all times to at least the market value of the
securities  loaned.  The Fund would continue to receive interest or dividends on
the securities loaned and would also earn interest on the investment of the loan
collateral.  The loan collateral would be invested only in U.S.  Treasury notes,
certificates  of  deposit  or  other  high-grade,   short-term   obligations  or
interest-bearing cash equivalents.  Although voting rights, or rights to consent
attendant to securities loaned, pass to the borrower,  such loans will be called
so that the securities may be voted if a material event affecting the investment
is to occur.

         As with  other  extensions  of  credit,  there  are  risks  of delay in
recovery  or even loss of rights in the  collateral  should the  borrower of the
securities  fail  financially.  The Fund will lend portfolio  securities only to
firms which have been approved in advance by the Fund's Board of Trustees, which
will monitor the  creditworthiness  of any such firms.  If the management of the
Fund  decides to make  securities  loans,  it is intended  that the value of the
securities  loaned by the Fund  would not  exceed 30% of the value of the Fund's
total  assets.  In the  Fund's  last  fiscal  year,  it did not  lend  portfolio
securities  with a value  exceeding 5% of its net assets and,  while it reserves
the right to do so,  the Fund has no  present  intention  of  lending  portfolio
securities with such a value during the coming year.

         Covered Call Options

         The Fund may write (sell)  covered  call  options on certain  portfolio
securities,  but  options  may not be written on more than 25% of the  aggregate
market value of any single  portfolio  security  (determined each time a call is
sold as of the  date of such  sale).  As  writers  of a call  option,  the  Fund
receives a premium less commission,  and, in exchange,  foregoes the opportunity
to profit from  increases in the market value of the security  covering the call
above the sum of the premium  and the  exercise  price of the option  during the
life of the option.  The  purchaser of such a call has the option of  purchasing
the  security  from the Fund's  portfolio at the option price during the life of
the option.  Portfolio  securities on which options may be written are purchased
solely on the basis of  investment  considerations  consistent  with the  Fund's
investment  objectives.  The  security  covering  the  call is  maintained  in a
segregated  account  of the  Fund's  custodian.  The Fund  does not  consider  a
security  covered by a call option to be  "pledged"  as that term is used in the
Fund's policy which limits the pledging or mortgaging of their assets.

         The Fund will purchase a call option only when entering into a "closing
purchase  transaction,"  i.e., a purchase of a call option on the same  security
with the same exercise  price and  expiration  date as a "covered"  call already
written by the Fund.  There is no assurance that the Fund will be able to effect
such closing  purchase  transactions  at a favorable  price;  if the Fund cannot
enter into such a  transaction  it may be  required  to hold a security  that it
might otherwise have sold. The Fund's  portfolio  turnover may increase  through
the  exercise  of  options  if the  market  price of the  underlying  securities
appreciates  and the Fund has not entered into a closing  purchase  transaction.
The commission on purchase or sale of a call option is higher in relation to the
premium than the  commission in relation to the price on purchase or sale of the
underlying security.

         Foreign Securities

         The Fund may  invest a portion  of its  assets in  foreign  securities.
Investment  in securities of foreign  companies and countries  involves  certain
considerations  and risks that are not typically  associated  with investment in
U.S.  Government  securities  and  securities  of  domestic  companies.  Foreign
companies  are  not  generally  subject  to  uniform  accounting,  auditing  and
financial  standards and  requirements  comparable  to those  applicable to 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.  Dividends and interest paid by foreign issuers may be subject to
withholding  and other  foreign  taxes which may decrease the net return on such
investments  as compared to interest paid to the Fund by the U.S.  Government or
by  domestic   companies.   In  addition,   there  may  be  the  possibility  of
expropriations, confiscatory taxation, political, economic or social instability
or diplomatic developments which could affect assets of the Fund held in foreign
countries.  The  value  of  foreign  securities  may be  adversely  affected  by
fluctuations  in the  relative  rates of 

<PAGE>

exchange  between the  currencies of different  nations and by exchange  control
regulations.  There may be less  publicly  available  information  about foreign
companies and governments  compared to reports and ratings  published about U.S.
companies.  Some foreign  securities markets have substantially less volume than
domestic  markets and  securities of some foreign  companies are less liquid and
more volatile than securities of comparable U.S.  companies.  In connection with
its  investments  in  foreign   securities  and  in  order  to  protect  against
uncertainty in future  exchange rates,  the Fund may engage in foreign  currency
exchange transactions.

         Debt Securities

         No more  than 5% of the  Fund's  net  assets  may be  invested  in debt
securities,  including convertible  securities,  rated below "BBB" by Standard &
Poor's Ratings Group ("Standard & Poor's") or the equivalent. If the rating of a
debt security is reduced below  investment  grade ("BBB" or higher),  management
will  consider  whatever  action  is  appropriate,  consistent  with the  Fund's
investment objective and policies.

         Bonds rated below "BBB" 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, if unrated by
such rating  organization,  determined to be of comparable quality by the Fund's
investment adviser).

         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 quality  securities will have an adverse effect on the Fund's net asset
value to the extent that 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,
the Fund 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 

<PAGE>

lower rated or unrated securities,  under these circumstances,  may be less than
the prices used in calculating the Fund's net asset value.

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

         Since  investors  generally  perceive  that  there  are  greater  risks
associated with the medium to lower quality debt securities of the type in which
the Fund may  invest a portion  of its  assets,  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 debt 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 debt
securities market, resulting in greater yield and price volatility.

         Medium to lower rated and comparable  unrated debt  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. The Fund's investment adviser
will  attempt to reduce these risks  through  portfolio  diversification  and by
analysis of each  issuer and its  ability to make timely  payments of income and
principal, as well as broad economic trends and corporate developments.

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

Investment Restrictions

         Fundamental  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" (as defined in the 1940 Act) of
the Fund's outstanding voting securities. The Fund may not:

         (1)......Issue  senior  securities,  except as  permitted by the Fund's
borrowing,  lending  and  commodity  restrictions,  and  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,  reverse repurchase  agreements,  dollar rolls, swaps and
any other financial  transaction  entered into pursuant to the Fund's investment
policies  as  described  in the  Prospectus  and this  Statement  of  Additional
Information and in accordance with applicable SEC pronouncements, as well as the
pledge, mortgage or hypothecation of the Fund's assets within the meaning of the
Fund's fundamental  investment restriction regarding pledging, are not deemed to
be senior securities.

         (2)......Borrow  money,  except  from banks as a  temporary  measure to
facilitate the meeting of redemption  requests or for extraordinary or emergency
purposes and except pursuant to reverse  repurchase  agreements or dollar rolls,
in all cases in amounts not exceeding 10% 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  and dollar
rolls) exceed 10% of the Fund's total assets.

         (3)......Guarantee  the securities of any other company, or , mortgage,
pledge, hypothecate or assign or otherwise encumber as security for indebtedness
its securities or receivables in an amount exceeding the amount of the borrowing
secured thereby.

         (4)......Purchase  securities of a company if the purchase would result
in the Fund's  having more than 5% of the value of its total assets  invested in
securities of such company.

         (5)......Purchase  securities of a company if the purchase would result
in the Fund's owning more than 10% of the outstanding  voting securities of such
company.

         (6)......Act  as an  underwriter,  except  as it  may  deemed  to be on
underwriter in a sale of restricted securities held in its portfolio.

         (7)......Make  loans,  except by purchase of debt  obligations in which
the Fund may invest  consistent with its investment  policies,  by entering into
repurchase  agreements or through the 

<PAGE>

lending of portfolio  securities,  in each case only to the extent  permitted by
the Prospectus and this Statement of Additional Information.

         (8)......Invest  in real estate,  commodities  or commodity  contracts,
except that the Fund may invest financial  futures contracts and related options
and in any other financial  instruments which may be deemed to be commodities or
commodity  contracts in which the Fund is not  prohibited  from investing by the
Commodity Exchange Act and the rules and regulations thereunder

         (9)......Purchase  securities  on "margin" or effect " short  sales" of
securities.

         (10) purchase  securities for the purpose of controlling  management of
other companies;

         (11) acquire the securities of any other domestic or foreign investment
company  or  investment  fund  (except  in  connection  with a plan of merger or
consolidation  with or acquisition of substantially all the assets of such other
investment  company);  provided,  however,  that nothing herein  contained shall
prevent  the Fund from  investing  in the  securities  issued  by a real  estate
investment  trust,  provided that such trust shall not be permitted to invest in
real estate or interests in real estate other than  mortgages or other  security
interests;

The Fund does not intend to enter into any reverse  repurchase  agreement,  lend
portfolio  securities or invest in securities  index put and call  warrants,  as
described in fundamental  investment  restrictions  (1), (2), (7) and (8) above,
during the coming year.

Non-fundamental Investment Restrictions.

It is the policy of the Fund not to concentrate its investments in securities of
companies  in any  particular  industry.  In  the  opinion  of  the  Commission,
investments  are  concentrated  in a  particular  industry  if such  investments
aggregate  25% or more of the Fund's total  assets.  The Fund's  policy does not
apply to investments in U.S. Government securities. The Fund has agreed to abide
by the  foregoing  non-fundamental  policy which it will not change  without the
affirmative  vote of a majority of the Fund's  outstanding  shares of beneficial
interest.

The following  restrictions have been designated as  non-fundamental  and may be
changed  by a  vote  of  the  Fund's  Board  of  Trustees  without  approval  of
shareholders.

The Fund may not:

         (1) purchase or retain the securities of any company if officers of the
Fund or  Trustees  of the Fund,  or  officers  and  directors  of its adviser or
principal  underwriter,  individually  own 

<PAGE>

more than one-half of 1% of the securities of such company or  collectively  own
more than 5% of the securities of such company; or

         (2) purchase (a)  securities  which at the time of  investment  are not
readily marketable,  (b) securities the disposition of which is restricted under
federal  securities  laws  (excluding   restricted  securities  that  have  been
determined by the Trustees of the Fund (or the person designated by them to make
such  determinations)  to be readily  marketable) and (c) repurchase  agreements
maturing in more than seven days,  if, as a result,  more than 15% of the Fund's
net assets would be invested in securities described in (a), (b), and (c) above.
    


         In addition,  in connection  with the offering of its shares in various
states and foreign countries, the Fund has agreed to abide by certain additional
restrictions  which may not be changed  without the  approval of the  regulatory
agencies in such states and foreign  countries (but which may be changed without
notice to or approval of the Fund's  shareholders).  These restrictions are that
the Fund will not: (1) purchase the  securities  of any issuer if such  purchase
would result in the Fund owning more than 10% of any class of securities of such
issuer;  (2) invest in uncovered puts or calls,  or straddles,  spreads,  or any
combination  thereof,  or in oil, gas or other mineral  leases or exploration or
development programs; (3) borrow in excess of 10% of gross assets taken at cost;
(4) pledge, mortgage,  hypothecate or otherwise encumber any assets of the Fund;
(5) invest in foreign  securities  (exclusive  of foreign  securities  listed on
recognized  domestic  or  foreign  securities  exchanges),  together  with other
investments  which are not  readily  marketable,  in excess of 5% of average net
assets;  and (6) invest more than 5% of its total assets in warrants,  valued at
the lower of cost or market, or more than 2% of its total assets in warrants, so
valued, which are not listed on either the New York or American Stock Exchanges.

         2. MANAGEMENT OF THE FUND

   
         The  Fund's  Board of  Trustees  provides  broad  supervision  over the

         investment   vehicles  for  the  variable  annuity  and  variable  life
         insurance  contracts  of various  insurance  companies  or for  certain
         qualified pension plans.

         Compensation of Officers and Trustees

         Commencing  on January 1,  1996,  each  series of the Trust will pay an
annual trustees' fee to each Trustee who is not affiliated with PGI, PMC, 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 each series,  estimated to
be approximately $2,069 for 1996. In addition, each series of the Trust will pay
a per meeting fee of $120 to each Trustee who is not  affiliated  with PGI, PMC,
PFD or PSC.  The Trust also will pay an annual  committee  participation  fee to
each  Trustee  who serves as a member of any  committees  established  to act on
behalf of one or more of the of Pioneer  mutual  funds.  Committee  fees will be
allocated  to the Trust on the basis of the Trust's  average  net  assets.  Each
Trustee who is a member of the Audit Committee for the Pioneer mutual funds will
receive an annual fee equal to 10% of the aggregate annual trustees' fee, except
the Committee Chair who will receive an annual trustees' fee equal to 20% of the
aggregate  annual  trustees' fee. The 1996 fees for the Audit Committee  members
and Chair are expected to be  approximately  $6,000 and  $12,000,  respectively.
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, will receive an annual fee equal to 5% of
the annual  trustees' fee, except the Committee Chair who will receive an annual
trustees'  fee equal to 10% of the annual  trustees'  fee. The 1996 fees for the
Pricing Committee members and Chair are expected to be approximately  $3,000 and
$6,000, respectively.  Any such fees paid to affiliates or interested persons of
PGI, PMC, PFD or PSC are reimbursed to the Trust under its Management Contract.

         The Fund pays no salaries or compensation  to any of its officers.  The
Fund paid an annual  trustees' fee of $5,000 and a payment of $300 plus expenses
per meeting attended,  to each Trustee who was not affiliated with PGI, PMC, PFD
or PSC and paid an annual  trustees'  fee of $500 plus  expenses to each Trustee
affiliated  with  PGI,  PMC,  PFD or PSC.  Any such  fees and  expenses  paid to
affiliates or interested  persons of PGI, PMC, PFD or PSC were reimbursed to the
Fund under its management contract.

         The following table sets forth certain  information with respect to the
compensation of each Trustee of the Fund for the year ended December 31, 1995:

         3. INVESTMENT ADVISER

   
         The  Fund  has   contracted   with  PMC,  60  State   Street,   Boston,
Massachusetts,  to act as its investment adviser.  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,  subject  to the  right of the  Fund's  trustees  to
disapprove any such purchase or sale. The Management  contract expires initially
on May 31, 1997, but it is renewable annually by vote of a majority of the Board
of  Trustees  of the Fund  (including  a majority  of the  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.  The
contract  terminates if assigned and may be terminated without penalty by either
party by vote of its Board of Directors or Trustees or vote of a majority of its
outstanding  securities  and the  giving  of sixty  days'  written  notice.  The
management contract was approved by the shareholders of the Fund at a meeting of
shareholders held on April 30, 1996.

As compensation for its management  services and expenses incurred,  and certain
expenses  which PMC incurs on behalf of the Fund,  the Fund pays PMC a basic fee
of  0.60%  of the  Fund's  average  daily  net  assets  (the  "Basic  Fee").  An
appropriate  percentage  of this  rate  (based  upon the  number  of days in the
current  month) of this  annual  Basic Fee is applied to the Fund's  average net
assets for the current month, giving a dollar amount which is the monthly fee.

Performance Fee Adjustment

The Basic Fee is  subject  to an upward or  downward  adjustment,  depending  on
whether  and to what  extent,  the  investment  performance  of the fund for the
performance  period  exceeds,  or is  exceeded  by,  the  record  of  the  index
determined by the Fund to be approprate over the same period.  The Trustees have
designated  the Lipper  Growth and Income  Funds  Index (the  "Index")  for this
purpose.  The Index  represents the arithmetic mean performance  (i.e.,  equally
weighted) of the thirty largest funds with a growth and income objective.

The  performance  period  consists of the current  month and the prior 35 months
("performance  period"). Each percentage point of difference (up to a maximum of
+/-10) is  multiplied  by a performance  adjustment  rate of 0.01%.  The maximum
annualized adjustment rate is +/- 0.10%. This performance  comparison is made at
the end of each month.  An  appropriate  percentage of this rate (based upon the
number of days in the current  month) is then applied 

<PAGE>

to the fund's  average net assets for the entire  performance  period,  giving a
dollar amount that is added to (or subtracted from) the Basic Fee.

The Fund's  performance is calculated  based on net asset value. For purposes of
calculating  the  performance   adjustment,   any  dividends  or  capital  gains
distributions  paid by the Fund are treated as if  reinvested  in Fund shares at
the net asset value as of the record date for payment.  The record for the Index
is based on change in value and is adjusted for any cash  distributions from the
companies whose securities whose securities comprise the Index.

Application of Performance Adjustment

The  application of the  performance  adjustment is illustrated by the following
hypothetical  example,  assuming  that the net  asset  value of the Fund and the
level of the  Index  were $10 and 100,  respectively,  on the  first  day of the
performance period.

                  Investment Performance *            Cumulative Change

                  First Day     End of Period       Absolute    Percentage
                                     Points

Fund                $ 10           $ 13               +$ 3        + 30%
Index                100            123               + 23        + 23%

* Reflects  performance  at net asset  value.  Any  dividends  or capital  gains
distributions  paid by the Fund are  treated as if  reinvested  in shares of the
Fund at net  asset  value  as of the  payment  date  and any  dividends  paid on
securities  which  comprise  the  Index  are  treated  as if  reinvested  on the
ex-dividend date.

The  difference  in  relative  performance  for  the  performance  period  is +7
percentage points. Accordingly,  the annualized management fee rate for the last
month of the performance  period would be calculated as follows:  An appropriate
percentage (based upon the number of days in the current month) of the Basic Fee
of 0.60% would be applied to the Fund's  average  daily net assets for the month
resulting in a dollar amount.  The +7 percentage  point difference is multiplied
by the  performance  adjustment  rate of 0.02%  producing  a rate of  0.14%.  An
appropriate  percentage  of this  rate  (based  upon the  number  of days in the
current  month) is then applied to the average daily net assets of the Fund over
the performance period resulting in a dollar amount which is added to the dollar
amount of the Basic Fee. The management fee paid is the dollar amount calculated
for the performance period. If the investment performance of the Fund during the
performance period was exceeded by the record of the Index, the dollar amount of
performance adjustment would be deducted from the Basic Fee.
<PAGE>

Because the adjustment to the Basic Fee is based on the comparative  performance
of the Fund and the record of the Index,  the controlling  factor is not whether
Fund  performance  is up or down, but whether it is up or down more or less than
the record of the Index.  Moreover,  the  comparative  investment of the Fund is
based solely on the relevant performance period without regard to the cumulative
performance over a longer or shorter period of time.

From time to time, the Trustees may determine that another securities index is a
more  appropriate  benchmark  than the  Index for  purposes  of  evaluating  the
perfromance of the Fund. In such event, a successor index may be substituted for
the Index.  However,  the  calculation  of the  performance  adjustment  for any
portion of the  performance  period prior to the adoption of the seccessor index
would still be based upon the Fund's performance compared to the Index.

The Fund's current  management  contract with PMC became  effective May 1, 1996.
Under  the  terms of the  contract,  beginning  on May 1, 1996 the Fund will pay
management fees at a rate equal to the Basic Fee plus or minus the amount of the
performance adjustment for the current month and the preceding 35 months. At the
end of each succeeding month, the performance period will roll forward one month
so that it is always a 36-month  period  consisting of the current month and the
prior 35 months as described above. If including the intial rolling  performance
period  (that  is,  the  period  prior to the  effectiveness  of the  management
contract),  has the  effect of  increasing  the Basic  Fee for any  month,  such
aggregate  prior  results  will be  treated as Index  neutral  for  purposes  of
calculating  the  performance   adjustment  for  such  month.   Otherwise,   the
performance adjustment will be made as described above.

The Basic Fee is computed  daily,  the  performance fee adjustment is calculated
once per month and the entire management fee is normally paid monthly.

Prior to May 1, 1996, as compensation  for its management  services and expenses
incurred, PMC received 0.50% per annum of the Fund's average daily net assets up
to $250,000,000, 0.48% of such assets between $250,000,000 and $300,000,000, and
0.45% of such assets in excess of  $300,000,000.  The fee was computed daily and
paid monthly.

                  During its fiscal years ended December 31, 1995,1994 and 1993,
the  Fund  paid or owed  management  fees to PMC of  approximately  $10,330,000,
$9,362,000 and $8,774,000, respectively.
    

         4. SHAREHOLDER SERVICING/TRANSFER AGENT

         The Fund has contracted with Pioneering Services  Corporation  ("PSC"),
60 State Street, Boston, Massachusetts,  to act as its dividend disbursing agent
and transfer agent.  This contract  terminates if assigned and may be terminated
without penalty by either party by vote of its Board

<PAGE>

of Directors or Trustees or a majority of its outstanding  voting securities and
the giving of sixty days' written notice.

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

         PSC receives an annual fee of $22.00 per  shareholder  account from the
Fund as compensation  for the services  described  above.  This fee is set at an
amount  determined  by vote of a majority of the Fund's  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.

         5. CUSTODIAN

         Brown Brothers Harriman & Co. (the "Custodian") is the custodian of the
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling the Fund's cash and securities, handling the receipt and delivery of
securities, and collecting interest and dividends on the Fund's investments. The
Custodian does not determine the investment policies of the Fund or decide which
securities  the  Fund  will  buy or  sell.  The Fund  may,  however,  invest  in
securities,  including  repurchase  agreements,  issued by the Custodian and may
deal with the  Custodian  as  principal in  securities  transactions.  Portfolio
securities may be deposited into the Federal  Reserve-Treasury  Department  Book
Entry System or the Depository Trust Company.

         6. PRINCIPAL UNDERWRITER

   
         PFD, 60 State Street,  Boston,  Massachusetts,  serves as the principal
underwriter  for the Fund in  connection  with the  continuous  offering  of its
shares.  The Fund has  entered  into an  Underwriting  Agreement  with PFD.  The
Underwriting  Agreement will continue from year to year if annually  approved by
the Trustees in conjunction with the continuance of the Plan (as defined below).
The Underwriting Agreement provides that PFD will bear the distribution expenses
of the Fund not borne by the Fund.  During the Fund's 1995, 1994 and 1993 fiscal
years, net underwriting commissions retained by PFD were approximately $923,858,
$990,413, $880,000 and $831,000, respectively.  Commissions reallowed to dealers
for the  1994,  1993  and  1992  fiscal  years  were  approximately  $6,147,056,
$6,589,413 and $7,303,666, respectively.
    

         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

<PAGE>

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,  state and  foreign
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 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  (other than  municipal  debt  securities  issued by state  political
subdivisions  or their  agencies or  instrumentalities)  pursuant to a bona fide
purchase of assets,  merger or other reorganization  provided (i) the securities
meet the investment objectives and policies of the Fund; (ii) the securities are
acquired by the Fund for investment and not for resale; (iii) the securities are
not restricted as to transfer either by law or liquidity of market; and (iv) the
securities have a value which is readily ascertainable (and not established only
by  evaluation  procedures)  as  evidenced  by a listing on the  American  Stock
Exchange  or the New  York  Stock  Exchange,  or by  quotation  under  the  NASD
Automated  Quotation  System.  An  exchange of  securities  for Fund shares will
generally be a taxable transaction to the shareholder.

         7. DISTRIBUTION PLAN

         The Fund has  adopted a plan of  distribution  pursuant  to Rule  12b-1
under the 1940 Act (the "Plan") pursuant to which the Fund may reimburse PFD for
its expenditures in financing any activity  primarily  intended to result in the
sale of the shares of the Fund.  Certain  categories of such  expenditures  have
been approved by the Board of Trustees and are set forth in the Prospectus.  See
"Distribution Plan" in the Prospectus.  The expenses of the Fund pursuant to the
Plan are  accrued on a fiscal  year basis and may not exceed the annual  rate of
0.25% of the Fund's average annual net assets.  In accordance  with the terms of
the Plan,  PFD  provides  to the Fund for  review by the  Trustees  a  quarterly
written report of the amounts  expended under the Plan and the purpose for which
such expenditures were made. In the Trustees' quarterly review of the Plan, they
will consider its continued  appropriateness  and the level of  compensation  it
provides.

         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 Plan 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 Plan by the Fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.
<PAGE>

         The Plan was  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
had any direct or indirect  financial  interest in the  operation  of the Plan),
cast in person at a meeting  called for the  purpose  of voting on the Plan.  In
approving the Plan, the Trustees identified and considered a number of potential
benefits which the Plan may provide.  The Board of Trustees  believes that there
is a reasonable  likelihood  that the Plan will benefit the Fund and its current
and future  shareholders.  Under its terms, the Plan remains in effect from year
to year provided such  continuance is approved  annually by vote of the Trustees
in the  manner  described  above.  The  Plan  may  not be  amended  to  increase
materially the annual  percentage  limitation of average net assets which may be
spent for the services described therein without approval of the shareholders of
the Fund,  and  material  amendments  of the Plan must also be  approved  by the
Trustees in the manner  described above. The 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 Fund (as defined in the 1940 Act). The Plan
was approved at a meeting of  shareholders  held on October 15,  1991.  The Plan
will  automatically  terminate in the event of its assignment (as defined in the
1940 Act).

   
         During the fiscal year ended December 31, 1995, the Fund incurred total
distribution  fees pursuant to the Plan of  $3,776,000.  Distribution  fees were
paid by the  Fund to PFD in  reimbursement  of  expenses  related  to  services,
shareholder accounts and to compensating dealers and sales personnel.
    
         8. INDEPENDENT PUBLIC ACCOUNTANTS

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

         9. 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 (subject to the right of the Trustees to reverse any such transaction).
The  primary   consideration  in  placing  portfolio  security  transactions  is
execution at the most favorable  prices.  Additionally,  in selecting brokers or
dealers, PMC will consider various relevant factors,  including, but not limited
to,  the size and type of the  transaction;  the  nature  and  character  of the
markets for the  security to be  purchased or sold;  the  execution  efficiency,
settlement  capability,  and  financial  condition  of the dealer;  the dealer's
execution services rendered on a continuing basis; and the reasonableness of any
dealer spreads.
<PAGE>

         In circumstances  where two or more broker-dealers are in a position to
offer  comparable  prices and  execution,  dealers may be  selected  who provide
brokerage and/or research services to the Fund and/or other investment companies
managed by PMC, or who 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.  Brokerage and research services may include
advice  concerning the value of securities;  the  advisability  of investing in,
purchasing  or  selling  securities;  the  availability  of  securities  or  the
purchasers or sellers of securities;  providing stock price quotation  services;
furnishing  analyses,  electronic  information  services,  manuals  and  reports
concerning  issuers,  industries,   securities,  economic  factors  and  trends,
portfolio  strategy,  performance of accounts,  comparative  fund statistics and
credit rating service  information;  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 it is anticipated that many transactions on behalf of the Fund
and other investment companies 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 receipt of research  from dealers may be useful to PMC in rendering
investment  management  services  to the Fund  and  other  investment  companies
managed by PMC, and conversely,  such information provided by brokers or dealers
who have executed  transaction orders on behalf of such other PMC clients may be
useful to PMC in carrying out its  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 it were to attempt to develop comparable information through its own
staff.

   
         The   Trustees   periodically   review   PMC's   performance   of   its
responsibilities  in connection with the placement of portfolio  transactions on
behalf of the Fund.  During the fiscal years ended December 31, 1995,  1994, and
1993,  the  Fund  paid or owed  total  brokerage  commissions  of  approximately
$x,xxx,xxx, $1,016,736 and $1,270,000, respectively.
    

         The Fund is managed by Pioneering Management Corporation ("PMC"), which
also serves as investment adviser to other mutual funds in the Pioneer group and
private  accounts  with  investment  objectives  similar  to those of the  Fund.
Securities  frequently  meet the investment  objectives of the Fund,  such other
mutual  funds in the  Pioneer  group and such other  private  accounts.  In such
cases, the decision to recommend a purchase to one mutual fund or account rather
than the other 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

<PAGE>

and  the  market  for  them.   Other  factors   considered  in  the   investment
recommendations  include other  investments which each client presently has in a
particular  industry and the  availability  of  investment  funds in each client
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 mutual  fund or
account in the same  issue may vary and the length of time that any mutual  fund
or account  may  choose to hold its  investment  in the same issue may  likewise
vary. To the extent that the Fund, another mutual fund in the Pioneer group or a
private  account  managed by PMC seeks to acquire the same security at about the
same  time,  the Fund may not be able to  acquire  as large a  position  in such
security  as it desires or it may have to pay a higher  price for the  security.
Similarly,  the Fund may not be able to obtain as large an execution of an order
to sell or as high a price for any particular  portfolio security if PMC decides
to sell on behalf of another  account  the same  portfolio  security at the same
time. On the other hand, if the same  securities  are bought or sold at the same
time  by  more  than  one  account,   the  resulting   participation  in  volume
transactions could produce better executions for the Fund or the 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. Although some of the other mutual funds in the Pioneer group have the same
general  investment  objectives  and  fundamental  policies  as the Fund,  their
portfolios do not generally  consist of the same investments as the Fund or each
other and their performance results are likely to differ from that of the Fund.

         10. DIVIDENDS AND TAX STATUS

         It is the Fund's policy to meet the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended (the "Code"),  for  qualification as a
regulated  investment  company.  The  requirements  relate to the sources of its
income,  diversification  of its  assets  and  distributions  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 receives, the Fund
will be relieved of the necessity of paying federal income tax.

         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 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 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.
<PAGE>

         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,  forward foreign currency contracts, foreign currencies, or payables
or receivables  denominated in a foreign  currency are subject to Section 988 of
the Code, which generally causes such gains and losses to be treated as ordinary
income  and  losses  and  may  affect  the  amount,   timing  and  character  of
distributions to shareholders.

         If the  Fund  acquires  stock in  certain  non-U.S.  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 lower  rating
categories or are unrated.  Investments in debt  obligations that are at risk of
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 ensure that it distributes sufficient income to preserve
its status as a regulated  investment  company and to avoid becoming  subject to
federal income or excise tax.

         If the Fund invests in certain  PIKs,  zero coupon  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  prior  to the  receipt  of the
corresponding  cash  payments.  However,  the  Fund  must
<PAGE>

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.

         At the time of an investor's  purchase of Fund shares, a portion of the
purchase price is often  attributable to realized or unrealized  appreciation in
the Fund's portfolio or undistributed taxable income of the Fund.  Consequently,
subsequent distributions 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 in reality represent a return of a portion of the investment.

   
         Redemptions  and exchanges are taxable  events.  Any loss realized by a
shareholder  upon the  redemption  or other  sales of shares  with a tax holding
period of six months or less will be treated as a long-term  capital loss to the
extent of any amounts treated as  distributions  of long-term  capital gain with
respect to such shares.

         In addition,  if shares  redeemed or exchanged  have been held for less
than 91 days, (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  certain
redemptions  may be  disallowed  under  "wash  sale" rules in the event of other
investments  in the Fund  (including  those made pursuant to automatic  dividend
reinvestment)  within a period of 61 days beginning 30 days before and ending 30
days after a redemption or other sale of shares.
    

         Options written by the Fund on certain securities 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 and
may affect the characterization as long-term or short-term of some capital gains
and losses  realized by the Fund.  Losses on certain  options 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) 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.  The effect of these rules may
be  mitigated  to the extent the Fund limits its  option-writing  to  "qualified
covered call options" on portfolio  stock.  The tax rules  applicable to options
and 

<PAGE>

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  available  to
corporations,  dividends  received  by the  Fund,  if any,  from  U.S.  domestic
corporations  in respect of any share of stock with a tax  holding  period of at
least 46 days (91 days in the case of certain preferred stock) in an unleveraged
position and distributed and designated by the Fund may be treated as qualifying
dividends.  Any corporate  shareholder  should consult its tax 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.  Corporate  shareholders  must meet the  minimum  holding
period requirement stated above (46 or 91 days), taking into account any holding
period  reductions from certain hedging or other positions that diminish risk of
loss,  with  respect to their Fund shares in order to qualify for the  deduction
and,  if they  borrow to  acquire  Fund  shares,  may be denied a portion of the
dividends-received  deduction.  The entire  qualifying  dividend,  including the
otherwise deductible amount, will be included in determining the excess (if any)
of a  corporation's  adjusted  current  earnings  over its  alternative  minimum
taxable  income,  which may  increase a  corporation's  alternative  minimum tax
liability.

         The Fund may be  subject  to  withholding  and other  taxes  imposed by
foreign  countries  with  respect to its  investments  in those  countries.  Tax
conventions  between certain countries and the U.S. may reduce or eliminate such
taxes.  The Fund does not expect to satisfy the requirements for passing through
to  shareholders  their pro rata shares of 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.

   
         Federal law requires that the Fund withhold 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 Applications, or on separate W-9
Forms, 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.
    

<PAGE>

         Provided  that 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.

   
         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.  This  description  does not  address the
special tax rules  applicable to particular  types of investors,  such as banks,
insurance  companies or tax exempt  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 any 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 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.
    

         11. DESCRIPTION OF SHARES

   
         The  Fund's  Declaration  of Trust  permits  its Board of  Trustees  to
authorize the issuance of an unlimited  number of full and fractional  shares of
beneficial  interest (without par value) which may be divided into such separate
series as the Trustees may establish.  Currently,  the Fund consists of only one
series.  The Trustees may establish  additional series of shares, and may divide
or combine the shares into a greater or lesser number of shares without  thereby
changing  the  proportionate  beneficial  interests.  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 only one class of shares of the Fund.  Each  share
represents an equal proportionate  interest with each other share. The shares of
any additional series would participate  equally in the earnings,  dividends and
assets of the  particular  series,  and would be entitled to vote  separately to
approve  investment  advisory  agreements or changes in investment  restrictions
Upon liquidation of the Fund, the Fund's  shareholders are entitled to share pro
rata in the Fund's net assets available for distribution to shareholders.

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 shares of each series of the Fund are entitled to vote separately to approve
investment  advisory  agreements  or changes  in  investment  restrictions,  but
shareholders  of all series

<PAGE>

vote together in the election and selection of Trustees and accountants.  Shares
of all series of the Fund vote  together  as a class on matters  that affect all
series 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.
    
See "Certain Liabilities."

   
12. CERTAIN LIABILITIES

The  Fund  has  previously   been  organized  as  a  Delaware   corporation,   a
Massachusetts corporation and a Massachusetts business trust and was reorganized
as a Delaware  business trust on May 1, 1996,  pursuant to an Agreement and Plan
of  Reorganization  approved  by the  shareholders  of the Fund.  As a  Delaware
business trust,  the Fund's  operations are governed by its Declaration of Trust
dated May 1, 1996. A copy of the fund's  Certificate of Trust, also dated May 1,
1996,  is on file  with the  office  of the  Secretary  of  State  of  Delaware.
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  of Trust  expressly  provides that the Fund is organized  under the
Delaware  Act and that the  Declaration  of Trust is to be  governed by Delaware
law. There is nevertheless a remote  possibility 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 become subject to personal liability.

To guard  against this risk,  the  Declaration  of Trust (I) contains an express
disclaimer  of  shareholder  liability for acts or  obligations  of the Fund and
provides  that  notice  of such  disclaimer  may be  given  in  each  agreement,
obligation or  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  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

<PAGE>

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

         13. DETERMINATION OF NET ASSET VALUE

   
         The net asset value per share of the Fund is determined as of the close
of regular trading on the New York Stock Exchange  (normally 4:00 P.M.,  Eastern
Time) on each day on which the New York Stock Exchange is open for business.  As
of the date of this  Statement  of  Additional  Information,  the New York Stock
Exchange is open for trading  every weekday  except for the following  holidays:
New Year's Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day,
Labor Day,  Thanksgiving Day and Christmas Day. The net asset value per share of
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.  On any day in which no purchase orders in good order for
the shares of the Fund are received  and no shares are tendered for  redemption,
the net asset value per share is not determined.
    

         The net asset  value per share of the Fund is  computed  by taking  the
amount of the value of all of its assets, less its liabilities,  and dividing it
by the number of  outstanding  shares.  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.

         14. SYSTEMATIC WITHDRAWAL PLAN

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

<PAGE>

deposited monthly or quarterly  directly into a bank account  designated by you,
or will be sent by check to you, or any person designated by you. 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
SWP  will be  credited  to the  SWP  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 SWP in a SWP account.  To the extent that such  redemptions
for periodic  withdrawals  exceed dividend income reinvested in the SWP account,
such  redemptions  will reduce and may  ultimately  exhaust the number of shares
deposited in the Plan account.  Redemptions are potentially 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 capital.

         The SWP 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 SWP  have  been
redeemed. The fees of PSC for maintaining the SWP is paid by the Fund.

         15. LETTER OF INTENTION

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

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

         16. INVESTMENT RESULTS

         Quotations, Comparisons, and General Information

         From  time to  time,  in  advertisements,  in sales  literature,  or in
reports to  shareholders,  the past  performance  of the Fund may be illustrated
and/or  compared  to  that  of  other  mutual  funds  with  similar   investment
objectives,  and to stock or other  relevant  indices.  For example,  the Fund's
performance may be compared to rankings prepared by Lipper Analytical  Services,
Inc.,  a widely  recognized  independent  service  which  monitors  mutual  fund
performance;  the  Standard & Poor's 500 Stock  Index ("S&P  500"),  an index of
unmanaged  groups  of  common  stock;  or the Dow Jones  Industrial  Average,  a
recognized unmanaged index of common stocks of 30 industrial companies listed on
the New York Stock  Exchange;  or the Frank  Russell  Indexes  ("Russell  1000,"
"2000," "2500," "3000") and Wilshire Total Market Value Index ("Wilshire 5000"),
recognized unmanaged indexes of broad-based common stocks.

         In addition, the performance of the Fund may be compared to alternative
investment  or savings  vehicles  and/or to indexes or  indicators  of  economic
activity,  e.g., inflation or interest rates.  Performance rankings and listings
reported in newspapers or national business and financial publications,  such as

                  Standardized Average Annual Total Returns
                  Quotations and Other Performance Quotations
<PAGE>

         One of the  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 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.  Past
performance cannot guarantee any particular future result.

         Generally,  performance illustrations will include or be accompanied by
the Fund's  average  annual total return over the prior one year,  five year and
ten year periods.  The average annual total return ("T") is computed by equating
the  value  at the  end of  the  period  ("ERV")  with  a  hypothetical  initial
investment  of  $1,000  ("P")  over a period  of years  ("n")  according  to the
following formula specified by the SEC: P(1+T)n = ERV.

         These  computations  will assume the  deduction  of the  maximum  sales
charge of 5.75% from the initial  investment,  the reinvestment of dividends and
distributions  at net asset value on the  appropriate  dates and a redemption of
the account at the end of the period.

   
         The  average  annual  compounded  total  return  of the  Fund  for  the
one-year, five-year, ten-year and life-of-Fund periods ending December 31, 1995,
was-19.37%, 13.58%, 11.25% and XX.XX%, respectively.
    

         The Fund may also present,  from time to time,  historical  information
depicting  the value of a  hypothetical  account  over the time  period from the
Fund's  inception  in 1928 until the present.  The Fund also may depict  summary
results of  assumed  investments  in the Fund for each of the  ten-calendar-year
periods  in the Fund's  history  and for the  ten-year  periods  which  began at
recognized  market highs or ended at recognized  market lows. An example of this
historical  information  describing various  performance  characteristics of the
Fund from 1928 until the  present is  contained  under the  caption  "Investment
Results" in this Statement of Additional Information.

         In presenting  investment results, the Fund may also include references
to certain  financial  planning  concepts,  including (a) an investor's  need to
evaluate his financial  assets and  obligations to determine how much to invest;

various  investments to determine  where to invest;  and (c) his need to analyze
his time frame for future  capital  needs to determine  how long to invest.  The
investor  controls  these  three  factors,  all  of  which  affect  the  use  of
investments in building assets.

Annual Growth Rate:
(Internal Rate of Return)                13.03%             14.96%
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 U.S.;
prior to March 1957 it consisted of 90 of the largest stocks.

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

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

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

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

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

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

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

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

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

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

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

Item 26.  Number of Holders of Securities

   
         At January 31, 1996,  there were  approximately  231,658 holders of the
Registrant's shares of beneficial interest.
    


Item  27. Indemnification

         Except for the Declaration of Trust dated January 8, 1985  establishing
the  Registrant  as a trust  under  Massachusetts  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 Declaration
of Trust  provides  that no Trustee or officer will be  indemnified  against any
liability of which the Registrant would otherwise be subject by reason of or for
willful  misfeasance,  bad faith, gross negligence or reckless disregard of such
person's duties.

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

                                    EXHIBIT A
                               MANAGEMENT CONTRACT

         THIS AGREEMENT  dated this 1st day of May, 1996 between Pioneer Fund, a
Delaware business trust (the "Trust"), and Pioneering Management Corporation,  a
Delaware corporation (the "Manager").

                               W I T N E S S E T H

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

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

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

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

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

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

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

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

         (c) The Trust shall  assume and shall pay: (i) charges and expenses for
fund accounting, pricing and appraisal services and related overhead, including,
to the extent such  services are  performed by personnel of the Manager,  or its
affiliates, office space and facilities and personnel compensation, training and
benefits;  (ii) the charges  and  expenses  of  auditors;  (iii) the charges and
expenses of any custodian, transfer agent, plan agent, dividend disbursing agent
and registrar  appointed by the Trust with respect to the Trust;  (iv) issue and
transfer  taxes   chargeable  to  the  Trust  in  connection   with   securities
transactions


                                      A-2
<PAGE>

to which the Trust is a party; (v) insurance  premiums,  interest charges,  dues
and fees for membership in trade  associations  and all taxes and corporate fees
payable by the Trust to federal, state or other governmental agencies; (vi) fees
and expenses involved in registering and maintaining  registrations of the Trust
and/or its shares with the Commission, state or blue sky securities agencies and
foreign  countries,  including the preparation of Prospectuses and Statements of
Additional  Information  for filing with the  Commission;  (vii) all expenses of
shareholders' and Trustees' meetings and of preparing, printing and distributing
prospectuses,  notices,  proxy statements and all reports to shareholders and to
governmental agencies; (viii) charges and expenses of legal counsel to the Trust
and the  Trustees;  (ix) any  distribution  fees paid by the Trust in accordance
with Rule 12b-1  promulgated  by the  Commission  pursuant to the 1940 Act;  (x)
compensation  of those  Trustees  of the  Trust who are not  affiliated  with or
interested  persons of the  Manager,  the Trust  (other than as  Trustees),  The
Pioneer  Group,  Inc.  or Pioneer  Trusts  Distributor,  Inc.;  (xi) the cost of
preparing and printing share certificates; and (xii) interest on borrowed money,
if any.

         (d) In addition to the expenses  described  in Section 2(c) above,  the
Trust shall pay all  brokers' and  underwriting  commissions  chargeable  to the
Trust in connection with securities transactions to which the Trust is a party.

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

                 (i) The fee  payable  hereunder  shall be composed of the Basic
Fee (defined  below) and a Performance  Adjustment  (defined below) to the Basic
Fee  based  upon the  investment  performance  of the Trust in  relation  to the
investment  record of a securities index determined by the Trustees of the Trust
to be appropriate over the same period.  The Trustees have initially  designated
the Lipper Growth & Income Funds Index (the "Index") for this purpose.

                 (ii)  From  time to  time,  the  Trustees  may by a vote of the
Trustees of the Trust voting in person, including a majority of its Trustees who
are not parties to this  Agreement  or  "interested  persons" (as defined in the
1940 Act) of any such parties, determine that another securities index is a more
appropriate  benchmark than the Index for purposes of evaluating the performance
of the Trust.  In such event,  after ten days' written notice to the Manager,  a
successor  index (the  "Successor  Index") may be  substituted  for the Index in
prospectively


                                      A-3
<PAGE>

calculating the Performance Adjustment. However, the calculation of that portion
of the  Performance  Adjustment  attributable  to any portion of the performance
period prior to the adoption of the Successor Index will still be based upon the
Trust's performance compared to the Index.

                 (iii) The Basic Fee is  payable  at an annual  rate of 0.60% of
the Trust's average daily net assets.

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

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

         The  initial  performance  period will  consist of the 36 month  period
beginning  June 1, 1993 and ending May 31,  1996.  Each  month  thereafter,  the
performance  period  shall  consist of the current  month plus the  preceding 35
months.  In the event that the  inclusion in the rolling  performance  period of
aggregate  results from prior to May 1, 1996 would have the effect of increasing
the Basic Fee for any month,  such  aggregate  prior  results will be treated as
Index neutral for purposes of calculating  the  performance  adjustment for such
month.

         The Trust's  investment  performance  will be measured by comparing the
(i) opening net asset value of one share of the Trust on the first  business day
of the performance period with (ii) the closing net asset value of the one share
of the  Trust as of the last  business  day of such  period.  In  computing  the
investment  performance  of the Trust and the  investment  record of the  Index,
distributions  of realized  capital gains,  the value of capital gains taxes per
share  paid  or  payable  on  undistributed  realized  long-term  capital  gains
accumulated  to the end of such  period  and  dividends  paid out of  investment
income on the part of the Trust,  and all cash  distributions  of the  companies
whose stock comprise the Index, will be treated as reinvested in accordance


                                      A-4
<PAGE>

with Rule 205-1 or any other  applicable rule under the Investment  Advisers Act
of 1940, as the same from time to time may be amended.

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

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

                 (v) In the event of  termination of this  Agreement,  the Basic
Fee then in effect  shall be computed  on the basis of the period  ending on the
last  business day on which this  Agreement  is in effect  subject to a pro rata
adjustment  based  on the  number  of days  elapsed  in the  current  month as a
percentage  of the  total  number  of days  in such  month.  The  amount  of any
Performance  Adjustment  to the Basic Fee will be  computed  on the basis of and
applied  to net  assets  averaged  over the 36 month  period  ending on the last
business  day on  which  this  Agreement  is in  effect,  provided  that if this
Agreement has been in effect less than 36 months,  the computation  will be made
on the basis of the period of time during which it has been in effect.

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

         (c) In  addition  to the  foregoing,  the Manager may from time to time
agree not to impose all or a portion of its fee otherwise  payable hereunder (in
advance of the time such fee or a portion thereof would otherwise accrue) and/or
undertake to pay


                                      A-5
<PAGE>

or  reimburse  the Trust  for all or a portion  of its  expenses  not  otherwise
required to be borne or  reimbursed  by the Manager.  Any such fee  reduction or
undertaking may be discontinued or modified by the Manager at any time.

         4.  It  is  understood   that  the  Manager  may  employ  one  or  more
sub-investment  advisers (each a "Subadviser")  to provide  investment  advisory
services  to the  Trust by  entering  into a  written  agreement  with each such
Subadviser;  provided,  that any such  agreement  first shall be approved by the
vote of a majority of the Trustees, including a majority of the Trustees who are
not "interested  persons" (as defined in the 1940 Act) of the Trust, the Manager
or any such  Subadviser,  at a meeting of  Trustees  called  for the  purpose of
voting  on such  approval  and by the  affirmative  vote of a  "majority  of the
outstanding  voting  securities" (as defined in the 1940 Act) of the Trust.  The
authority  given to the Manager in Sections 1 through 6 hereof may be  delegated
by it under any such agreement;  provided,  that any Subadviser shall be subject
to the same restrictions and limitations on investments and brokerage discretion
as the Manager.  The Trust agrees that the Manager shall not be  accountable  to
the Trust or the Trust's  shareholders for any loss or other liability  relating
to  specific  investments  directed by any  Subadviser,  even though the Manager
retains  the  right to  reverse  any such  investment,  because,  in the event a
Subadviser is retained,  the Trust and the Manager will rely almost  exclusively
on the expertise of such Subadviser for the selection and monitoring of specific
investments.

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

         6. (a) Nothing in this  Agreement will in any way limit or restrict the
Manager or any of its officers,  directors, or employees from buying, selling or
trading in any securities for its or their own accounts or other  accounts.  The
Manager  may  act  as an  investment  advisor  to  any  other  person,  firm  or
corporation,  and may perform  management  and any other  services for any other
person, association,  corporation, firm or other entity pursuant to any contract
or  otherwise,  and take any action or do any thing in 


                                      A-6
<PAGE>

connection  therewith or related thereto;  and no such performance of management
or other  services or taking of any such action or doing of any such thing shall
be in  any  manner  restricted  or  otherwise  affected  by  any  aspect  of any
relationship  of the  Manager  to or with the Trust or deemed to violate or give
rise to any duty or  obligation  of the Manager to the Trust except as otherwise
imposed by law. The Trust recognizes that the Manager, in effecting transactions
for its various accounts, may not always be able to take or liquidate investment
positions in the same security at the same time and at the same price.

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

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

     7. This  Agreement  shall  become  effective  on the date  hereof and shall
remain in force until May,  1997 and from year to year  thereafter,  but only so
long as its  continuance  is approved  annually by a vote of the Trustees of the
Trust voting in person,


                                      A-7
<PAGE>

including a majority of its  Trustees  who are not parties to this  Agreement or
"interested  persons"  (as  defined in the 1940 Act) of any such  parties,  at a
meeting of Trustees  called for the  purpose of voting on such  approval or by a
vote of a "majority of the  outstanding  voting  securities"  (as defined in the
1940 Act) of the  Trust,  subject  to the right of the Trust and the  Manager to
terminate this contract as provided in Section 8 hereof.

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

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

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

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

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

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

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

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

                                    EXHIBIT B
                      AGREEMENT AND PLAN OF REORGANIZATION


         THIS  AGREEMENT  AND  PLAN OF  REORGANIZATION  is made as of the day of
April,  1996, by and between Pioneer Fund, a  Massachusetts  business trust (the
"Current  Fund"),  and Pioneer Fund, a business trust duly formed under the laws
of the State of Delaware (the "Successor Trust").

         This  Agreement  is  intended  to  be  and  is  adopted  as a  plan  of
reorganization  within the  meaning of Section  368 (a)(1) of the U.S.  Internal
Revenue  Code of 1986,  as amended (the  "Code"),  and is intended to effect the
reorganization  (a  "reorganization")  of the Current  Fund,  as a new  separate
series of the Successor Trust. The  reorganization  will involve the transfer of
all of the assets of the Current Fund to the sole series of the Successor  Trust
(the  "Successor  Fund") solely in exchange for (1)  assumption by the Successor
Fund of all  liabilities  of the Current  Fund and (2) the issuance of shares of
beneficial interest (the "Successor Shares") by the Successor Trust on behalf of
the Successor Fund to the Current Fund, followed by the pro rata distribution on
the Closing Date (as defined  below) of the  Successor  Shares to the holders of
shares  of   beneficial   interest  of  the  Current  Fund  (the  "Current  Fund
Shareholders")  in exchange for their shares of the Current Fund in  liquidation
and  termination  of the  Current  Fund,  all  upon  the  terms  and  conditions
hereinafter set forth in this Agreement.

         In  consideration  of the premises and of the covenants and  agreements
hereinafter set forth the parties hereto covenant and agree as follows.

1.       TRANSFER OF ASSETS OF THE CURRENT  FUND IN EXCHANGE FOR  ASSUMPTION  OF
         LIABILITIES  AND ISSUANCE OF SUCCESSOR  SHARES OF THE SUCCESSOR  TRUST;
         TERMINATION OF THE CURRENT FUND

         1.1  Subject to the terms and  conditions  set forth  herein and on the
basis of the representations  and warranties  contained herein, the Current Fund
agrees  to  transfer  all of the  assets  of the  Current  Fund as set  forth in
paragraph  1.2 and assign and transfer all of its  liabilities  to the Successor
Fund of the Successor Trust which has been established solely for the purpose of
acquiring all of the assets and assuming all of the  liabilities  of the Current
Fund. The Successor Trust has not issued any Shares or commenced operations. The
Successor  Trust on behalf of the Successor Fund agrees that in exchange for all
of the assets of the Current Fund (1) the Successor Fund shall assume all of the
liabilities of the Current Fund, whether contingent or otherwise, then existing,
and further (2) the Successor Trust shall deliver to the Current Fund the number
of full and fractional  Successor


                                      B-1
<PAGE>

Shares equal to the value of the assets of the Current Fund  transferred  to the
Successor  Fund,  minus the  liabilities  of the  Current  Fund  assumed  by the
Successor Fund (the "Net Assets"),  as described in paragraph 3.1 on the Closing
Date provided for in paragraph  3.1. Such  transactions  shall take place at the
Closing provided for in paragraph 3.1.

         1.2 The assets of the Current Fund to be acquired by the Successor Fund
shall include,  without  limitation,  all cash,  cash  equivalents,  securities,
receivables (including interest and dividends receivable),  any claims or rights
of action or rights to register  shares under  applicable  securities  laws, any
books or records of the  Current  Fund and other  property  owned by the Current
Fund and any  deferred or prepaid  expenses  shown as assets on the books of the
Current Fund on the Closing Date provided for in paragraph 3.1.

         1.3 Immediately upon delivery to the Current Fund of Successor  Shares,
any duly authorized officer of the Current Fund shall cause the Current Fund, as
the then sole shareholder of the Successor Fund, to (i) elect as Trustees of the
Successor Trust the persons who currently serve as Trustees of the Current Fund;
(ii) ratify the  selection  of the  independent  accountants;  (iii)  approve an
investment  advisory  agreement  for the  Successor  Fund in the form  currently
approved by the shareholders of the Current Fund; (iv) approve a Rule 12b-1 plan
in the form  currently in place with respect to the Current Fund; and (v) adopt,
on behalf of the Successor Fund, the investment objectives,  investment policies
and investment restrictions of the Current Fund.

         1.4 As provided in paragraph  3.4, on the Closing Date the Current Fund
will  distribute in liquidation  the Successor  Shares pro rata in proportion to
the Current Fund's respective shares of beneficial  interest in the Current Fund
("Current Fund Shares") to Current Fund  Shareholders of record determined as of
the close of business  on the Closing  Date,  in exchange  for the Current  Fund
Shares.  Such distribution will be accomplished by the transfer of the Successor
Shares then  credited to the account of the Current Fund on the share records of
the  Successor  Trust to open  accounts  on those  records  in the  names of the
Current Fund Shareholders and representing the respective pro rata number of the
Successor  Shares  received from the Successor  Trust on behalf of the Successor
Fund due the Current  Fund  Shareholders.  The  Successor  Trust shall not issue
certificates representing Successor Shares in connection with such distribution.
Fractional  Successor  Shares  shall be  rounded  to the third  place  after the
decimal point.

                                      B-2
<PAGE>

         1.5 As soon as  practicable  after the  distribution  of the  Successor
Shares as set forth in Section 1.4, the Current Fund shall be terminated and any
such further  actions shall be taken in connection  therewith as are required by
applicable law.

         1.6  Ownership  of  the  Successor   Shares  of  each   Successor  Fund
Shareholder shall be maintained  separately on the books of Pioneering  Services
Corporation as the Successor Trust's shareholder services and transfer agent.

         1.7 Any transfer  taxes payable upon issuance of Successor  Shares in a
name other than the registered holder of the Current Fund Shares on the books of
the  Current  Fund as of that  time  shall be paid by the  person  to whom  such
Successor Shares are to be distributed as a condition of such transfer.

2.       VALUATION

         2.1 The value of the  Current  Fund's Net Assets to be  acquired by the
Successor Trust on behalf of the Successor Fund hereunder shall be the net asset
value  computed  as of  the  valuation  time  provided  in  the  Current  Fund's
prospectus on the Closing Date using the valuation  procedures  set forth in the
Current Fund's current prospectus or statement of additional information.

         2.2 The value of full and fractional  Successor  Shares to be issued in
exchange  for the Current  Fund's Net Assets  shall be equal to the value of the
Net  Assets of the  Current  Fund on the  Closing  Date,  and the number of such
Successor  Shares  shall equal the number of full and  fractional  Current  Fund
Shares of the Current Fund on the Closing Date.

         2.3 All computations of value shall be made by Brown Brothers  Harriman
& Co. as custodian for the Current Fund and the Successor Trust.

3.       CLOSING AND CLOSING DATE

         3.1 The  transfer of the  Current  Fund's  assets in  exchange  for the
assumption  by the  Successor  Fund of the Current  Fund's  liabilities  and the
issuance of Successor Shares to the Current Fund, as described  above,  together
with related acts necessary to consummate such acts (the "Closing"), shall occur
at the offices of Hale and Dorr at 60 State Street, Boston,  Massachusetts 02109
on April 30, 1996 ("Closing  Date"),  or at such other place or date on or prior
to May 31, 1996 as the parties  may agree in writing.  All acts taking  place at
the Closing  shall be deemed to take place 


                                      B-3
<PAGE>

simultaneously as of the last daily  determination of the net asset value of any
Current Fund or at such other time and/or place as the parties may agree.

         3.2 In the  event  that on the  Closing  Date  (a) the New  York  Stock
Exchange is closed to trading or trading thereon is restricted or (b) trading or
reporting  of  trading  on said  Exchange  or in any  market in which  portfolio
securities  of any  Current  Fund  are  traded  is  disrupted  so that  accurate
appraisal  of  the  value  of the  total  net  assets  of the  Current  Fund  is
impracticable,  the Closing shall be postponed until the first business day upon
which  trading  shall  have been fully  resumed  and  reporting  shall have been
restored.

         3.3 The  Current  Fund shall  deliver at the Closing a  certificate  or
separate  certificates of an authorized officer stating that it has notified the
Custodian,   as  custodian  for  the  Current   Fund,  of  the  Current   Fund's
reorganization as the Successor Fund.

         3.4  Pioneering  Services  Corporation,  as  shareholder  services  and
transfer agent for the Current Fund,  shall deliver at the Closing a certificate
as to the  conversion  on its books and records of the Current Fund  Shareholder
account to an account as a holder of Successor Shares. The Successor Trust shall
issue and deliver to the Current Fund a  confirmation  evidencing  the Successor
Shares to be credited on the Closing Date or provide  evidence  satisfactory  to
the Current Fund that such  Successor  Shares have been  credited to the Current
Fund's  account on the books of the Successor  Trust.  At the Closing each party
shall  deliver  to the other  such  bills of sale,  checks,  assignments,  stock
certificates, receipts or other documents as such other party or its counsel may
reasonably request.

         3.5 Portfolio  securities  that are not held in book-entry  form in the
name of the  Custodian as record  holder for the Current Fund shall be presented
by the Current Fund to the Custodian for examination no later than five business
days  preceding the Closing  Date.  Portfolio  securities  which are not held in
book-entry  form shall be delivered by the Current Fund to the Custodian for the
account of the Successor Fund on the Closing Date,  duly endorsed in proper form
for  transfer,  in such  condition as to  constitute  good  delivery  thereof in
accordance with the custom of brokers, and shall be accompanied by all necessary
federal and state stock transfer stamps or a check for the appropriate  purchase
price  thereof.  Portfolio  securities  held  of  record  by  the  Custodian  in
book-entry  form on  behalf  of the  Current  Fund  shall  be  delivered  to the
Successor  Fund  by the  Custodian  by  recording  the  transfer 


                                      B-4
<PAGE>

of beneficial  ownership thereof on its records.  The cash delivered shall be in
the form of currency or by the Custodian  crediting the Successor  Fund' account
maintained with the Custodian with immediately available funds.

<PAGE>

proceedings  and  the  Current  Fund is not a  party  to,  or  subject  to,  the

restrictions on the full transfer thereof,  including such restrictions as might
arise under the Securities Act of 1933, as amended;

                  4.1.L.  The  execution,   delivery  and  performance  of  this
Agreement  will have  been  duly  authorized  prior to the  Closing  Date by all
necessary action on the part of the Current Fund and this Agreement  constitutes
a valid and binding  obligation  of the Current Fund  enforceable  in accordance
with its terms, subject to the approval of the Current Fund's Shareholders; and

8.       FURTHER CONDITIONS PRECEDENT TO OBLIGATIONS OF THE CURRENT FUND AND THE

         8.2 On the Closing Date, no action,  suit or other  proceeding shall be

         8.3 All consents of other  parties and all other  consents,  orders and

the  Commission and of state  securities  authorities)  deemed  necessary by the
Successor  Trust or the Current  Fund to permit  consummation,  in all  material
respects,  of the  transactions  contemplated  hereby shall have been  obtained,
except  where  failure to obtain  any such  consent,  order or permit  would not

                                      B-11
<PAGE>

                           8.5.A.  The  acquisition  of all of the  assets  of a
                  Current Fund by the Successor  Fund solely in exchange for the
                  issuance  of  Successor  Shares  to the  Current  Fund and the
                  assumption by the Successor Fund of all of the  liabilities of
                  the Current Fund,  followed by the distribution in liquidation
                  by the Current  Fund of such  Successor  Shares to the Current
                  Fund  Shareholders  in exchange for their  Current Fund Shares
                  and the  termination  of the Current Fund,  will  constitute a
                  reorganization  within the meaning of Section 368(a)(1) of the
                  Code, and the Current Fund and the Successor Fund will each be
                  "a party to a  reorganization"  within the  meaning of Section
                  368(b) of the Code;

                           8.5.B.  No  gain or loss  will be  recognized  by the
                  Current Fund upon (i) the transfer of all of its assets to the
                  Successor   Fund  solely  in  exchange  for  the  issuance  of
                  Successor Shares to the Current Fund and the assumption by the
                  Successor Fund of the Current Fund's  liabilities and (ii) the
                  distribution  by the Current Fund of the  Successor  Shares to
                  the Current Fund Shareholders;

                           8.5.C.  No  gain or loss  will be  recognized  by any
                  Successor  Fund upon its receipt of all of the Current  Fund's
                  assets  solely in exchange for the  issuance of the  Successor
                  Shares to the Current Fund and the assumption by the Successor
                  Fund of all of the liabilities of the Current Fund;

                           8.5.D.  The tax  basis of the  assets  acquired  by a
                  Successor  Fund from the Current  Fund will be the same as the
                  tax  basis  of  those  assets  in  the  Current  Fund's  hands
                  immediately before the transfer;

                           8.5.E.  The tax  holding  period of the assets of the
                  Current Fund in the hands of the  Successor  Fund will include
                  the Current Fund's tax holding period for those assets;

                           8.5.F.  The  Current  Fund's  Shareholders  will  not
                  recognize  gain or loss  upon  the  exchange  of all of  their
                  Current Fund Shares solely for Successor Shares as part of the
                  transaction;

                           8.5.G. The tax basis of the Successor Shares received
                  by Current Fund  Shareholders in the transaction  will be, for
                  each  shareholder,  the same as the tax  basis of the  Current
                  Fund Shares surrendered in exchange therefor; and

                                      B-12
<PAGE>

                           8.5.H. The tax holding period of the Successor Shares
                  received by Current Fund Shareholders  will include,  for each
                  such Shareholder,  the tax holding period for the Current Fund
                  Shares  surrendered  in exchange  therefor,  provided that the
                  Current Fund Shares were held as capital assets on the date of
                  the exchange.

The  Current  Fund  and   Successor   Trust  each  agree  to  make  and  provide
representations  with respect to the Current Fund and the  Successor  Fund which
are  reasonably  necessary  to  enable  Hale  and  Dorr to  deliver  an  opinion
substantially as set forth in this paragraph 8.5, which opinion may address such
other federal income tax  consequences,  if any, as Hale and Dorr believes to be
material to the transaction.

         Each of the  foregoing  conditions  precedent to the  obligations  of a
party,  except  for the  receipt  of the  opinion  of Hale and Dorr set forth in
paragraph 8.5, may be waived by that party.

9.       BROKERAGE FEES AND EXPENSES

         9.1 The Successor Trust and the Current Fund each represent and warrant
to the other that there are no broker's or finder's  fees payable in  connection
with the transactions contemplated hereby.

         9.2 The Current  Fund and the  Successor  Fund shall each be liable for
its own expenses  incurred in connection with entering into and carrying out the

Current Fund will be assumed by the Successor Fund as part of the transactions.

10.      ENTIRE AGREEMENT

         The  Successor  Trust and the Current Fund agree that neither party has
made any representation, warranty or covenant not set forth herein and that this
Agreement   constitutes   the  entire   agreement   between  the  parties.   The
representations,  warranties and covenants  contained  herein or in any document
delivered   pursuant  hereto  or  in  connection   herewith  shall  survive  the
consummation of the transactions contemplated hereunder.

11.      TERMINATION

         11.1 This  Agreement may be  terminated by the mutual  agreement of the
Successor Trust and the Current Fund. In addition, either the Successor Trust or
the Current Fund may at its option  terminate  this Agreement at or prior to the
Closing Date because:

                                      B-13
<PAGE>

                           11.1.A.  There exists a material  breach by the other
                  party  of  any   representations,   warranties  or  agreements
                  contained  herein to be  performed  at or prior to the Closing
                  Date; or

                           11.1.B.  A condition herein expressed to be precedent
                  to the obligations of the  terminating  party has not been met
                  and it reasonably appears that it will not or cannot be met.

         11.2 In the event of any such termination,  there shall be no liability
for damages on the part of the  Successor  Trust or the Current  Fund,  or their
respective trustees,  directors or officers, to the other party or its trustees,
directors or officers.

12.      AMENDMENT

         This Agreement may be amended,  modified or supplemented in such manner
as may be mutually  agreed upon in writing by the  parties;  provided,  however,
that   following  the  approval  of  this   Agreement  by  the  Current   Funds'
Shareholders,  no such  amendment may have the effect of changing the provisions
for  determining  the number of Successor  Shares to be paid to the Current Fund
Shareholders  under  this  Agreement  to  the  detriment  of  the  Current  Fund
Shareholders without their further approval.
