Prospectus
August 30, 1996
(revised March 19, 1997)
    

      Pioneer Bond Fund (the "Fund")  seeks  current  income from a high quality
portfolio  with due regard to  preservation  of capital and  prudent  investment
risk. Consistent therewith, the Fund also seeks to maintain dividend payments at
a  relatively  stable  level.  At least 85% of the Fund's  total  assets must be
invested in debt  securities  issued or guaranteed by the United States ("U.S.")
Government  or its agencies or  instrumentalities,  debt  securities  (including
convertible  securities)  rated  within  the three  highest  grades by the major
recognized bond services and comparably rated commercial paper and cash and cash
equivalents.  The Fund may invest the balance (up to 15%) of its total assets in
debt  securities  that  are  rated in the  fourth  highest  grade  by the  major
recognized bond services and in commercial paper that is of comparable quality.

      Fund returns and share  prices  fluctuate  and the value of your  account,
upon redemption, may be more or less than the value of your original investment.
Shares in the Fund are not deposits or obligations of, or guaranteed or endorsed
by, any bank or depository institution, and the shares are not federally insured
by the Federal Deposit Insurance  Corporation,  the Federal Reserve Board or any
other government agency.

I. EXPENSE INFORMATION

     This table is designed to help you understand the charges and expenses that

Fund. The table reflects annual operating expenses based upon actual expenses of
the Class A and Class B shares for the fiscal  year  ended  June 30,  1996.  For
Class C shares,  operating  expenses are based on expenses  that would have been
incurred if Class C shares had been outstanding for the entire fiscal year ended
June 30, 1996.

  + Class C shares were first offered on January 31, 1996.

(1) Purchases of $1 million or more and certain  purchases by  participants in a
    group plan are not subject to an initial  sales charge but may be subject to
    a contingent  deferred sales charge ("CDSC") as further described under "How
    to Sell Fund Shares."

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

 Example:

     You would pay the following expenses on a $1,000 investment,  assuming a 5%
annual  return,  reinvestment  of all dividends and  distributions  and that the
percentage amounts listed under "Annual Operating Expenses" remain the same each
year.

                        1 Year    3 Years    5 Years    10 Years
                       --------- ---------- ---------- ----------
Class A Shares            $56       $81        $107       $182
Class B Shares*
 - Assuming complete
 redemption at end of
 period                   $60       $91        $125       $207
 - Assuming no
 redemption               $20       $61        $105       $207
Class C shares**
 - Assuming complete
 redemption at end of
 period                   $31       $67        $115       $247
 - Assuming no
 redemption               $22       $67        $115       $247

- ---------

 *   Class B shares  convert  to  Class A shares  eight  years  after  purchase;
     therefore, Class A share expenses are used after year eight.

**   Class C shares redeemed during the first year after purchase are subject to
     a 1% CDSC.

     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.

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

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

III. INVESTMENT OBJECTIVES AND POLICIES

     The Fund's  primary  objective  is to provide  current  income  from a high
quality  portfolio  with due  regard to  preservation  of  capital  and  prudent
investment risk. The Fund has a secondary  objective of maintaining a relatively
stable level of dividends;  however,  the level of dividends  will be maintained
only if consistent with preserving the high quality of the Fund's portfolio.

     At least  85% of the  Fund's  total  assets  must be  invested  in (a) debt
securities  issued or  guaranteed  by the U.S.  Government  or its  agencies  or
instrumentalities,  (b) investment-grade  securities,  that is, debt securities,
including  convertible  securities,  that are  rated  "A" or higher by the major
recognized  bond services (for a description  of ratings see the Appendix to the
Statement of Additional Information),  and comparably rated commercial paper and
(c) cash and cash  equivalents  (such as  certificates  of  deposit,  repurchase
agreements maturing in one week or less and bankers' acceptances).

     The Fund may also invest up to 15% of its total assets in debt  securities,
including convertible securities, which are rated in the fourth highest grade by
the major  recognized  bond services and  commercial  paper which is comparable.
Securities  in the fourth  highest  grade (i.e.,  rated Baa by Moody's  Investor
Services,  Inc. or BBB by Standard & Poor's Ratings Group) are considered medium
grade,  neither  highly  protected  nor poorly  secured,  with some  elements of
uncertainty   over  any   great   length   of  time  and   certain   speculative
characteristics as well.

     None of the Fund's  portfolio may be invested in debt securities  which are
rated below the fourth  highest  grade or are unrated,  except that the Fund may
hold debt securities the ratings of which are reduced subsequent to purchase.
The Fund may not invest in preferred or common stocks.

     The  Fund  may  invest  in  the   following   mortgage-backed   securities.
Collateralized    mortgage    obligations   ("CMOs")   are   obligations   fully
collateralized  by a portfolio  of  mortgages  or  mortgage-related  securities.
Payments of  principal  and  interest on the  mortgages  are passed to a special
purpose entity,  then through to the holders of the CMOs on the same schedule as
they are received,  although  certain  classes of CMOs have priority over others
with  respect  to  the  receipt  of  prepayments  on the  mortgages.  Therefore,
depending on the type of CMOs in which the Fund invests,  the  investment may be
subject  to a  greater  or  lesser  risk  of  prepayment  than  other  types  of
mortgage-related securities. A real estate mortgage investment conduit ("REMIC")
is a form of CMO that  qualifies  for special tax  treatment  under the Internal
Revenue Code of 1986,  as amended (the "Code").  The Fund may acquire  "regular"
interests  in REMICs but does not  intend,  under  current  tax law,  to acquire
residual  interests  in  REMICs.   Mortgage-backed   securities  are  derivative
securities and provide for payments based on or derived from the  performance of
the underlying mortgage

                                       4

<PAGE>

assets. Risks associated with mortgage-backed  securities include the failure of
a counter-party to meet its  commitments,  adverse interest rate changes and the
effects of prepayments on mortgage cash flows. When interest rates decline,  the
value of an investment in debt obligations can be expected to rise.  Conversely,
when interest rates rise the value of an investment in debt  obligations  can be
expected to decline.  Like other debt obligations,  when interest rates rise the
value of a  mortgage-backed  security  generally  will  decline;  however,  when
interest  rates are  declining,  the value of  mortgage-backed  securities  with
prepayment  features may not increase as much as that of other debt obligations.
Mortgage-backed   securities  may  be  less  effective  than   traditional  debt
obligations  of  similar  maturity  at  maintaining  yields  during  periods  of
declining interest rates.

     Not  more  than  15% of  the  Fund's  assets  may be  invested  in  foreign
securities  and not more than 5% of its total  assets may be invested in foreign
securities  that are not listed on a  recognized  foreign or domestic  exchange,
provided  that  purchases  of  Canadian   securities  are  not  subject  to  the
limitations in this paragraph.  Investments in foreign securities may be subject
to  risks  including,  but not  limited  to,  foreign  taxes  and  restrictions,
illiquidity and  fluctuations  in currency  values.  In addition,  the financial
information available on issuers of foreign debt securities is frequently not as
accurate or complete as would be available for a comparable domestic issuer. See
"Other Policies and Risks" in the Statement of Additional Information.

     The Fund's  portfolio  will be fully  managed  by  purchasing  and  selling
securities,  as well as holding  selected  securities  to  maturity.  The Fund's
investment  manager  employs  "cycle  analysis" in the  management of the Fund's
portfolio.  Cycle  analysis is the process of managing  the Fund's  portfolio by
analyzing  the business and credit cycles of the economy to identify and monitor
trends  in  interest  rates  and  to  identify   fixed-income   securities  with
characteristics most likely to meet the Fund's objectives at given stages in the
cycles. Relying on analysis of economic indicators,  as well as price, yield and
maturity  data  of  individual   securities,   this  process   requires  ongoing
adjustments  to the  portfolio  based on the relative  values or  maturities  of
individual  debt  securities  or  changes  in the  creditworthiness  or  overall
investment merit of an issue.

     Any such change in the  portfolio  may result in  increases or decreases in
the Fund's current income  available for distribution to shareholders and in its
holding of debt  securities  which sell at moderate to  substantial  premiums or
discounts  from face value.  If the Fund's  expectations  of changes in interest
rates or its evaluation of the normal yield relationships between two securities
prove to be incorrect,  the Fund's income, net asset value and potential capital
gain may be reduced or its potential capital loss may be increased.  An increase
in interest rates will generally reduce the value of portfolio investments (and,
therefore,  the net asset  value of the  shares of the  Fund),  and a decline in
interest rates will generally increase their value.

     It is the  policy  of the Fund not to  engage  in  trading  for  short-term
profits.  The Fund will engage in portfolio trading if it believes a transaction
net of costs (including  custodian's fees) will contribute to the achievement of
its  investment  objective.  See  "Financial  Highlights"  for actual  portfolio
turnover rates.

     The foregoing objectives and investment policies (other than the discussion
of "cycle analysis") may not be changed without shareholder approval. Government
securities  include U.S.  Treasury  obligations  such as bills,  bonds and notes
which  principally  differ  in their  interest  rates,  maturities  and times of
issuance,  and obligations issued or guaranteed by U.S.  Government  agencies or
instrumentalities  supported  by the full faith and credit of the U.S.  Treasury
(securities  of the  Government  National  Mortgage  Association,  "GNMA"),  the
authority of the U.S.  Government to purchase certain  obligations of the issuer
(securities of the Federal National Mortgage  Association,  "FNMA"), the limited
authority  of the issuer to borrow  from the U.S.  Treasury  (securities  of the
Student  Loan  Marketing  Association)  or only the  credit  of the  issuer.  No
assurance can be given that the U.S.  Government will provide  financial support
to U.S. Government agencies or  instrumentalities  in the future,  other than as
set forth above,  since it is not legally  obligated to do so. Interest payments
of U.S. Treasury  obligations are generally fixed. Other investment policies and
restrictions  on  investment  are  described  in  the  Statement  of  Additional
Information,  including  a policy on  lending  portfolio  securities.  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, six of whom are not
"interested  persons"  of the Fund as defined in the  Investment  Company Act of
1940, as amended (the "1940 Act"). The Board meets at least quarterly. By virtue
of the functions  performed by PMC as investment  adviser,  the Fund requires no
employees  other  than  its  executive  officers,  all  of  whom  receive  their
compensation from PMC or other sources. The Statement of Additional  Information
contains the names and general  background of each Trustee and executive officer
of the Fund.

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

     Research and management for the Fund is the responsibility of a team of
portfolio managers and analysts focusing on fixed income securities. Members of
the team meet regularly to discuss holdings, prospective investments and
portfolio composition. Mr. Sherman Russ is the senior member of the fixed income
team. Mr. Russ joined PMC in 1983.

     Day-to-day  management of the Fund has been the responsibility of Mr. Russ,
a Senior Vice President of PMC and Vice President of the Fund, since March 1988.
Mr. Russ has 33 years of investment experience.
    

                                       5

<PAGE>

     Investment  advisory services are provided to the Fund by PMC pursuant to a
management contract between PMC and the Fund. PMC is responsible for the overall
management of the Fund's business affairs,  subject only to the authority of the
Board of Trustees.  PMC is a wholly-owned  subsidiary of The Pioneer Group, Inc.
("PGI"), a Delaware  corporation.  Pioneer Funds Distributor,  Inc. ("PFD"),  an
indirect wholly-owned  subsidiary of PGI, is the principal underwriter of shares
of the Fund.

     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. In an effort to avoid conflicts of
interest  with the Fund,  the Fund and PMC have adopted a Code of Ethics that is
designed to maintain a high standard of personal  conduct by directing  that all
personnel  defer to the  interests  of the Fund and its  shareholders  in making
personal securities transactions.

     Under  the  terms  of its  contract  with  the  Fund,  PMC  assists  in the
management  of the  Fund and is  authorized  in its  discretion  to buy and sell
securities  for the  account of the Fund.  PMC pays all the  ordinary  operating
expenses,  including  executive salaries and the rental of 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 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  regulatory
agencies,  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 Fund who are not affiliated  with or interested  persons of PMC,
the Fund (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  in which two or more  broker-dealers  are in a position  to offer
comparable  prices and  execution,  consideration  may be given to  whether  the
broker-dealer provides investment research or brokerage services or sells shares
of any Pioneer  mutual fund or other funds for which PMC or any other  affiliate
or  subsidiary  serves as  investment  adviser or manager.  See the Statement of
Additional  Information for a further description of PMC's brokerage  allocation
practices.

     As compensation for its management  services and certain expenses which PMC
incurs,  PMC is  entitled  to a  management  fee equal to 0.50% per annum of the
Fund's  average daily net assets.  The fee is normally  computed  daily and paid
monthly.  See "Expense  Information" in this Prospectus and "Investment Adviser"
in the Statement of Additional Information.

     John F. Cogan,  Jr.,  Chairman and President of the Fund,  Chairman of PFD,
President  and a  Director  of PGI and  Chairman  and a Director  of PMC,  owned
approximately 14% of the outstanding capital stock of PGI as of the date of this
Prospectus.

V. FUND SHARE ALTERNATIVES

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

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

     Class B Shares.  If you plan to invest up to  $250,000,  Class B shares are
available to you.  Class B shares are sold without an initial sales charge,  but
are subject to a CDSC of up to 4% if redeemed  within six years.  Class B shares
are subject to distribution  and service fees at a combined annual rate of 1% of
the Fund's average daily net assets  attributable to Class B shares. Your entire
investment in Class B shares is available to work for you from the time you make
your  investment,  but the higher  distribution  fee paid by Class B shares will
cause your Class B shares (until  conversion) to have a higher expense ratio and
to pay lower  dividends,  to the extent dividends are paid, than Class A shares.
Class B shares will automatically  convert to Class A shares,  based on relative
net asset value, approximately eight years after the initial purchase.

                                       6

<PAGE>

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

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

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

VI. SHARE PRICE

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

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

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

     Telephone Purchases.  Your account is automatically  authorized to have the
telephone  purchase  privilege  unless you  indicate  otherwise  on your Account
Application  or by writing  to  Pioneering  Services  Corporation  ("PSC").  The
telephone  purchase  option  may be used to  purchase  additional  shares for an
existing  fund  account;  it may not be used to establish a new account.  Proper
account  identification will be required for each telephone purchase.  A maximum
of $25,000 per account may be  purchased by  telephone  each day. The  telephone
purchase privilege is available to 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  predesignated  bank  account.
Telephone  purchases may not be made for 30 days after the establishment of your
bank of record or any change to your bank information.

     Telephone  purchases  will  be  priced  at the net  asset  value  plus  any
applicable sales charge next determined after PSC's

                                       7

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.

Class A Shares

     You may buy Class A shares at the public offering price,  including a sales

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

     No sales  charge is payable at the time of  purchase on  investments  of $1
million  or more  or for  purchases  by  participants  in  certain  group  plans
(described below) subject to a CDSC of 1% which may be imposed in the event of a
redemption of Class A shares within 12 months of purchase. See "How to Sell Fund
Shares." 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.  Broker-dealers who receive a commission in connection with Class A
share  purchases  at net asset value by 401(a) or 401(k)  retirement  plans with
1,000 or more eligible  participants or with at least $10 million in plan assets
will be required to return any commission  paid or a pro rata portion thereof if
the  retirement  plan redeems its shares within 12 months of purchase.  See also
"How to Sell Fund Shares." 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 12 calendar  months.  In
connection with PGI's acquisition of Mutual of Omaha Fund Management Company and
contingent  upon the  achievement  of certain sales  objectives,  PFD may pay to
Mutual of Omaha  Investor  Services,  Inc.  50% of PFD's  retention of any sales
commission on sales of the Fund's Class A shares through such dealer.  From time
to  time,  PFD  may  elect  to  reallow  the  entire  initial  sales  charge  to
participating  dealers  for all Class A sales with  respect to which  orders are
placed  during a particular  period.  Dealers to whom  substantially  the entire
sales charge is  reallowed  may be deemed to be  underwriters  under the federal
securities laws.

     Qualifying  for a Reduced Sales  Charge.  Class A shares of the Fund may be
sold at a reduced or  eliminated  sales  charge to certain  group plans  ("Group
Plans") under which a sponsoring  organization makes recommendations to, permits
group  solicitation  of, or otherwise  facilitates  purchases by, its employees,
members  or  participants.  Class A shares  of the Fund may be sold at net asset
value  without  a sales  charge  to  401(k)  retirement  plans  with 100 or more
participants  or at  least  $500,000  in plan  assets.  Information  about  such
arrangements is available from PFD.

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

     Reduced  sales  charges are  available for purchases of $100,000 or more of
Class A shares (excluding any reinvest-

                                       8

<PAGE>

ments of  dividends  and  capital  gains  distributions)  made within a 13-month
period  pursuant  to a Letter of Intent  ("LOI")  which  may be  established  by
completing the Letter of Intent section of the Account Application.  The reduced
sales charge will be the charge that would be  applicable to the purchase of the
specified  amount of Class A shares as if the shares had all been  purchased  at
the same time. A purchase not made pursuant to an LOI may be included if the LOI
is  submitted  to PSC within 90 days of such  purchase.  You may also obtain the
reduced sales charge by including the value (at current  offering  price) of all
your  Class A shares  in the Fund and all other  Pioneer  mutual  funds  held of
record as of the date of your LOI in the amount used to determine the applicable
sales charge for the Class A shares to be purchased  under the LOI. Five percent
of your total intended purchase amount will be held in escrow by PSC, registered
in your name, until the terms of the LOI are fulfilled.

     You are not  obligated  to purchase  the amount  specified in your LOI. If,
however,  the amount  actually  purchased  during the 13-month period is more or
less than that  indicated in your LOI, an adjustment in the sales charge will be
made.  If a payment to cover actual sales charges is due, it must be paid to PFD
within 20 days after PFD or your dealer sends you a written  request or PFD will
direct PSC to liquidate  sufficient shares from your escrow account to cover the
amount due. See the Statement of Additional Information for more information.

     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 Class A 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.

Class B Shares

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

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

     The CDSC for  Class B shares  subject  to a CDSC  upon  redemption  will be
determined as follows:

      Year Since             CDSC as a Percentage of Dollar
       Purchase                  Amount Subject to CDSC
- -------------------------   --------------------------------
 First                                      4.0%
 Second                                     4.0%
 Third                                      3.0%
 Fourth                                     3.0%
 Fifth                                      2.0%
 Sixth                                      1.0%
 Seventh and thereafter                     none

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

     Class B shares will automatically convert into Class A shares at the end of
the  calendar  quarter that is eight years after the  purchase  date,  except as
noted below.  Class B shares acquired by exchange from Class B shares of another
Pioneer  fund will  convert into Class A shares based on the date of the initial
purchase and the applicable CDSC.  Class B shares acquired through  reinvestment
of  distributions  will  convert  into  Class A shares  based on the date of the
initial purchase to which such shares relate.  For this purpose,  Class B shares
acquired through  reinvestment of distributions will be attributed to particular
purchases of Class B shares in accordance  with such  procedures as the Trustees
may  determine  from time to time.  The  conversion of Class B shares to Class A
shares is subject to the continuing  availability  of a ruling from the Internal
Revenue Service ("IRS"),  which the Fund has obtained,  or an opinion of counsel
that such  conversions  will not  constitute  taxable  events  for  federal  tax
purposes.  There can be no  assurance  that such ruling  will  continue to be in
effect  at  the  time  any  particular  conversion  would  normally  occur.  The
conversion  of Class B shares to Class A shares will not occur if such ruling is
no longer in effect and such an opinion is not available and, therefore, Class B
shares would  continue to be subject to higher  expenses than Class A shares for
an indeterminate period.

Class C Shares

     You may buy Class C shares at net asset value per share next computed after
receipt of a purchase  order without the  imposition of an initial sales charge;
however,  Class C shares redeemed within one year of purchase will be subject to
a CDSC of 1%. The charge will be  assessed on the amount  equal to the lesser of
the current  market  value or the  original  purchase  cost of the shares  being
redeemed.  No CDSC will be  imposed on  increases  in  account  value  above the
initial  purchase  price,  including  shares  derived from the  reinvestment  of
dividends or capital gains  distributions.  Class C shares do not convert to any
other Class of Fund shares.

                                       9

<PAGE>

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

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

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

     The CDSC on Class B shares 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) 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);  (c) the  distribution is from a 401(a) or 401(k)  retirement
plan and is a return of excess employee deferrals or employee contributions; (d)
the  distribution is from an IRA, 403(b) or  employer-sponsored  retirement plan
and is to be  rolled  over to or  reinvested  in the same  class of  shares in a
Pioneer  mutual  fund and which  will be  subject  to the  applicable  CDSC upon
redemption;  (e) the distribution is in the form of a loan to a participant in a
plan which permits loans (each  repayment of the loan will constitute a new sale
which  will be  subject  to the  applicable  CDSC upon  redemption);  or (f) the
distribution  is from a qualified  defined  contribution  plan and  represents a
participant's   directed  transfer   (provided  that  this  privilege  has  been
pre-authorized through a prior agreement with PFD regarding participant directed
transfers).

     The CDSC on Class C shares and on any Class A shares  subject to a CDSC may
be waived or reduced as follows:  (a) for automatic  redemptions as described in
"Systematic  Withdrawal Plans" (limited to 10% of the value of the account); (b)
if 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; (c) if the  distribution 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 (d) if the
distribution is to a participant in an employer-sponsored retirement plan and is
(i) a return of excess employee  deferrals or  contributions,  (ii) a qualifying
hardship  distribution  as defined  by the Code,  (iii)  from a  termination  of
employment,  (iv) in the form of a loan to a participant in a plan which permits
loans,  or (v) 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 any  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. The CDSC
on  any  shares  subject  to a  CDSC  will  not be  applicable  if  the  selling
broker-dealer  elects,  with PFD's approval,  to waive receipt of the commission
normally paid at the time of the sale.

     Broker-Dealers.  An order for any Class of Fund shares received by PFD from
a  broker-dealer  prior to the  close of  regular  trading  on the  Exchange  is
confirmed at the price  appropriate for that Class as determined at the close of
regular  trading on the Exchange on the day the order is received,  provided the
order is received prior to PFD's close of business  (usually,  5:30 p.m. Eastern
Time). It is the  responsibility  of  broker-dealers  to transmit orders so that
they  will be  received  by PFD  prior  to its  close  of  business.  PFD or its
affiliates  may  provide  additional  compensation  to  certain  dealers or such
dealers' affiliates based on certain objective criteria established from time to
time by PFD.  All such  payments  are made out of PFD's or the  affiliate's  own
assets. These payments will not change the price an investor will pay for shares
or the amount that the Fund will receive from such sale.

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

VIII. HOW TO SELL FUND SHARES

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

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

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

   [bullet] If you are selling shares from a  non-retirement  account or an IRA,
            you may use any of the methods described below.

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

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

   [bullet] you wish to sell over $50,000 worth of shares,

   [bullet] your account registration or address has changed within the last 30
            days,

   [bullet] the check is not being mailed to the address on your account
            (address of record),

   [bullet] the check is not being made out to the account owners, or

   [bullet] the sale  proceeds are being  transferred  to a Pioneer  mutual fund
            account with a different registration.

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

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

     By Telephone or by Fax.  Your account is  automatically  authorized to have
the telephone redemption privilege unless you indicate 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,  except IRAs. A maximum of $50,000 per account per
day may be  redeemed by  telephone  or fax and the  proceeds  may be received by
check or by bank wire or electronic  funds transfer.  To receive the proceeds by
check:  the check must be made payable  exactly as the account is registered and
the check 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 wire 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 and fax redemptions will
be priced as  described  above.  You are  strongly  urged to  consult  with your
financial representative prior to requesting a telephone redemption.

     Selling Shares Through Your  Broker-Dealer.  The Fund has authorized PFD to
act as its  agent  in the  repurchase  of  shares  of the  Fund  from  qualified
broker-dealers  and reserves the right to terminate  this procedure at any time.
Your broker-dealer must receive your request before the close of business on the
Exchange  and  transmit it to PFD before PFD's close of business to receive that
day's  redemption  price.  Your  broker-dealer  is responsible for providing all
necessary documentation to PFD and may charge you for its services.

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

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

                                       11

<PAGE>

respect to Class A shares  purchased by 401(a) or 401(k)  retirement  plans with
1,000 or more eligible participants or with at least $10 million in plan assets.

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

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

IX. HOW TO EXCHANGE FUND SHARES

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

     Telephone Exchanges.  Your account is automatically  authorized to have the
telephone  exchange  privilege  unless you  indicate  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
FactFone(SM),  will be  recorded.  You are  strongly  urged to consult with your
financial   representative  prior  to  requesting  a  telephone  exchange.   See
"Telephone Transactions and Related Liabilities" below.

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

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

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

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

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

X. DISTRIBUTION PLANS

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

     Pursuant  to the  Class A Plan,  the  Fund  reimburses  PFD for its  actual
expenditures to finance any activity primarily intended to result in the sale of
Class A shares or to provide services to holders of Class A shares, provided the
categories  of  expenses  for which  reimbursement  is made are  approved by the
Fund's  Board of  Trustees.  As of the  date of this  Prospectus,  the  Board of
Trustees has approved the following categories of expenses for Class A shares of
the Fund: (i) a service fee to be paid to qualified  broker-dealers in an amount
not to exceed  0.25% per annum of the Fund's  daily net assets  attributable  to
Class A shares; (ii) reimbursement to PFD for its expenditures for broker-dealer
commissions  and employee  compensation  on certain  sales of the Fund's Class A
shares with no initial  sales charge (See "How to Buy Fund  Shares");  and (iii)
reimbursement to PFD for expenses

                                       12

<PAGE>

incurred  in  providing   services  to  Class  A  shareholders   and  supporting
broker-dealers  and other  organizations  (such as banks and trust companies) in
their efforts to provide such services. Banks are currently prohibited under the
Glass-Steagall Act from providing certain underwriting or distribution services.
If a bank was  prohibited  from acting in any capacity or  providing  any of the
described  services,  management  would  consider what action,  if any, would be
appropriate.

     Expenditures of the Fund pursuant to the Class A Plan are accrued daily and
may not exceed  0.25% of the Fund's  average  daily net assets  attributable  to
Class A shares.  Distribution  expenses  of PFD are  expected  to  substantially
exceed the distribution  fees paid by the Fund in a given year. The Class A Plan
does not provide for the carryover of reimbursable expenses beyond twelve months
from the time the Fund is first invoiced for an expense.  The limited  carryover
provision  in the Class A 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 Class A Plan, the Fund has twelve months to reimburse any
expense which it incurs prior to such termination or  non-continuance,  provided
that payments by the Fund during such twelve-month period shall not exceed 0.25%
of the Fund's average daily net assets during such period.  The Class A Plan may
not be amended  to  increase  materially  the annual  percentage  limitation  of
average net assets which may be spent for the services described therein without
approval of the shareholders of the Fund.

     Both the  Class B and the  Class C Plans  provide  that the Fund will pay a
distribution  fee at the annual  rate of 0.75% of the Fund's  average  daily net
assets attributable to the applicable Class of shares and will pay PFD a service
fee at the  annual  rate  of  0.25%  of the  Fund's  average  daily  net  assets
attributable  to that Class of  shares.  The  distribution  fee is  intended  to
compensate  PFD for its  distribution  services to the Fund.  The service fee is
intended to be additional  compensation  for personal  services  and/or  account
maintenance  services  with  respect  to  Class B or  Class C  shares.  PFD also
receives the proceeds of any CDSC imposed on the  redemption of Class B or Class
C shares.

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

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

     When a broker-dealer sells Class B or Class C shares and elects, with PFD's
approval, to waive its right to receive the commission normally paid at the time
of sale, PFD may cause all or a portion of the distribution fees described above
to be paid to the broker-dealer.

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

XI. DIVIDENDS, DISTRIBUTIONS AND TAXATION

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

     Under the Code,  the Fund will be  subject  to a  nondeductible  4% 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.

     Each business day the Fund declares a dividend  consisting of substantially
all of its net investment income (earned interest income less expenses).  Shares
being purchased will begin earning dividends on the first business day following
receipt of payment for purchased shares. Shares continue to earn dividends up to
and  including the date of  redemption.  Dividends are normally paid on the last
business  day of  the  month  or  shortly  thereafter.  Distributions  from  net
short-term  capital gains, if any, may be paid with such  dividends.  The Fund's
policy is to make  distributions  from net long-term  capital gains,  if any, in
December.  Dividends  from income and/or  capital gains may also be paid at such
other times as may be necessary for the Fund to avoid  federal  income or excise
tax.

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

                                       13

<PAGE>

     Generally,  dividends  from the Fund's net investment  income,  income from
securities  lending,  market  discount  income,  certain  net  realized  foreign
exchange gains, and net short-term  capital gains are taxable as ordinary income
under the Code,  and dividends  from the Fund's net long-term  capital gains are
taxable as long-term capital gains.

     The  Fund's   dividends  and   distributions   will  not  qualify  for  any
dividends-received deduction available to corporate shareholders.

     The Fund may be subject to foreign withholding taxes or other foreign taxes
on income (possibly including, in some cases, capital gains) from certain of its
foreign  investments,  which  will  reduce  the  yield on or return  from  those
investments.  The Fund  anticipates  that it generally  will not qualify to pass
such taxes through to its  shareholders,  who will generally  neither treat such
taxes as additional income nor be entitled to any associated foreign tax credits
or deductions.

     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 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
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. A state income (and possibly local income and/or  intangible
property)  tax  exemption  is  generally  available  to the  extent  the  Fund's
distributions  are  derived  from  interest  on (or,  in the case of  intangible
property  taxes,  the  value of its  shares is  attributable  to)  certain  U.S.
Government obligations,  provided in some states that certain reporting or other
requirements are satisfied. The Fund will not attempt to and may not satisfy all
such   requirements  in  all  states.   Non-U.S.   shareholders  and  tax-exempt
shareholders  are subject to tax  treatment  that is  different  than  described
above.  Shareholders should consult their own tax advisor regarding state, local
and other applicable tax laws.

XII. SHAREHOLDER SERVICES

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

Account and Confirmation Statements

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

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

Additional Investments

     You may add to your account by sending a check  (minimum of $50 for Class A
shares and $500 for Class B and Class C shares) to PSC (account number and Class
of shares should be clearly  indicated).  The bottom  portion of a  confirmation
statement  may be used as a  remittance  slip  to make  additional  investments.
Additions to your  account,  whether by check or through a Pioneer  Investomatic
Plan, are invested in full and  fractional  shares of the Fund at the applicable
offering  price in effect as of the close of 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,   payroll   deduction  or  through  a  Pioneer
Investomatic  Plan.  A Pioneer  Investomatic  Plan  provides  for a  monthly  or
quarterly  investment by means of a preauthorized  electronic  funds transfer or
draft drawn on a checking  account.  Pioneer  Investomatic  Plan investments are
voluntary,  and you may  discontinue  the  Plan  without  penalty  upon 30 days'
written  notice to PSC. PSC acts as agent for the 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 to you  information
about the tax status of dividends and distributions.

Distribution Options

     Dividends and capital gains  distributions,  if any, will  automatically be
invested in additional shares of the Fund, at the applicable net asset value per
share, unless you indicate another option on the Account Application.  Two other
options  available are (a) dividends in cash and capital gains  distributions in
additional  shares;  and (b) all dividends and capital  gains  distributions  in
cash. These two options are not available,  however, for retirement plans or for
an account with a net asset value of less than $500. Changes in the distribution
option may be made by written request to PSC.

                                       14

<PAGE>

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

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 Pioneer Fund or Pioneer II).
Invested  dividends may be in any amount.  There are no fees or charges for this
service. Retirement plan shareholders may only direct dividends to accounts with
identical  registrations  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 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 distributions 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.

Telephone Transactions and Related Liabilities

     Your account is  automatically  authorized  to have  telephone  transaction
privileges  unless you  indicate  otherwise on your  Account  Application  or by
writing to PSC. You may purchase, sell or exchange Fund shares by telephone. For
personal assistance, call 1-800-225-6292 between 8:00 a.m. and 9:00 p.m. Eastern
time on weekdays.  See "How to Buy Fund  Shares,"  "How to Sell Fund Shares" and
"How  to  Exchange   Fund  Shares"  for  more   information.   Computer-assisted
transactions  are 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.  To
confirm that each transaction  instruction received by telephone is genuine, the
Fund will record each telephone  transaction,  require the caller to provide the
personal  identification  number  ("PIN") for the account and send you a written
confirmation of each telephone  transaction.  Different  procedures may apply to
accounts that are  registered to non-U.S.  citizens or that are held in the name
of an  institution  or in the  name  of an  investment  broker-dealer  or  other
third-party.  If reasonable  procedures,  such as those described above, are not
followed,  the Fund may be liable for any loss due to unauthorized or fraudulent
instructions.  The Fund may implement other procedures from time to time. In all
other  cases,  neither  the  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 mutual fund 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 Buy Fund  Shares,"  "How to Exchange  Fund Shares," "How to Sell Fund Shares"
and "Telephone Transactions and Related Liabilities." Call PSC for assistance.

Retirement Plans

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

Telecommunications Device for the Deaf (TDD)

     If you have a hearing disability and access to 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.

Systematic Withdrawal Plans

     If your account has a total value of at least  $10,000 you may  establish a
SWP providing for fixed payments at regular intervals.  Withdrawals from Class B
and Class C share accounts are limited to 10% of the value of the account at the
time the SWP is  implemented.  See "Waiver or Reduction of  Contingent  Deferred
Sales Charge" for more information.  Periodic checks of $50 or more will be sent
to you, or any person designated by you, monthly or quarterly and your

                                       15

<PAGE>

periodic  redemptions  of shares  may be taxable  to you.  Payments  can be made
either by check or electronic  transfer to a bank account designated by 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 Class A shares of the
Fund at a time  when you have a SWP in  effect  may  result  in the  payment  of
unnecessary sales charges and may therefore be disadvantageous.

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

Reinstatement Privilege (Class A Shares Only)

     If you  redeem  all or part of your  Class A shares  of the  Fund,  you may
reinvest all or part of the redemption  proceeds without a sales charge in Class
A shares of the Fund if you send a written  request to PSC not more than 90 days
after your shares were redeemed.  Your redemption proceeds will be reinvested at
the next  determined net asset value of the Class A shares of the Fund in effect
immediately  after  receipt of the written  request for  reinstatement.  You may
realize  a gain or loss for  federal  income  tax  purposes  as a result  of the
redemption,  and  special  tax  rules may apply if a  reinstatement  occurs.  In
addition, if a redemption resulted in a loss and an investment is made in shares
of the Fund within 30 days before or after the  redemption,  you may not be able
to recognize the loss for federal income tax purposes. Subject to the provisions
outlined  under "How to Exchange  Fund Shares"  above,  you may also reinvest in
certain  other  Pioneer  mutual  funds;  in this case you must meet the  minimum
investment  requirement for each fund you enter. The 90-day reinstatement period
may be extended by PFD for periods of up to one year for shareholders  living in
areas that have  experienced  a natural  disaster,  such as a flood,  hurricane,
tornado or earthquake.

     The options and services available to shareholders,  including the terms of
the  Exchange  Privilege  and the  Pioneer  Investomatic  Plan,  may be revised,
suspended,  or terminated  at any time by PFD or by the Fund.  You may establish
the services described in this section when you open your account.  You may also
establish or revise many of them on an existing account by completing an Account
Options Form, which you may obtain by calling 1-800-225-6292.

XIII. THE FUND

     The Fund is an open-end diversified management investment company (commonly
referred to as a mutual fund) organized as a Massachusetts corporation on August
16, 1978 and reorganized as a Massachusetts business trust on December 31, 1985.
The Fund will recognize stock certificates  representing  shares of Pioneer Bond
Fund, Inc. issued prior to its reorganization as a Massachusetts  business trust
as  evidence  of  ownership  of an  equivalent  number of  shares of  beneficial
interest.  Any shareholder desiring to surrender a stock certificate to the Fund
for  a  share  certificate  representing  an  equivalent  number  of  shares  of
beneficial  interest  may do so by making a written  request for the exchange to
PSC. The request must be accompanied by the surrendered  stock certificate which
must be  endorsed  on the back  exactly  in the  manner  as the  certificate  is
registered.

     The Fund has  authorized  an  unlimited  number  of  shares  of  beneficial
interest and the  Trustees are  authorized  to create  additional  series of the
Fund.  The  Fund is not  required  to hold  annual  meetings,  although  special
meetings  may be called for the  purposes  of  electing  or  removing  Trustees,
changing fundamental investment restrictions or approving a management contract.
The Trustees  have the  authority,  without  further  shareholder  approval,  to
classify and  reclassify  the shares of the Fund, or any new series of the Fund,
into one or more classes.  As of the date of this Prospectus,  the Trustees have
authorized the issuance of three Classes of shares,  designated Class A, Class B
and  Class C.  The  shares  of each  Class  represent  an  interest  in the same
portfolio of investments of the Fund.  Each Class has equal rights as to voting,
redemption,  dividends and  liquidation,  except that each Class bears different
distribution  and  transfer  agent  fees and may bear  other  expenses  properly
attributable to the particular Class.  Class A, Class B and Class C shareholders
have exclusive voting rights with respect to the Rule 12b-1  distribution  plans
adopted  by holders  of those  shares in  connection  with the  distribution  of
shares.

     When issued and paid for in accordance with the terms of the Prospectus and
Statement  of  Additional  Information,  shares of the Fund are  fully-paid  and
non-assessable. Shares will remain on deposit with the Fund's transfer agent and
certificates will not normally be issued.  The Fund reserves the right to charge
a fee for the issuance of Class A shares certificates;  certificates will not be
issued for Class B or Class C shares.

XIV. INVESTMENT RESULTS

     The Fund may from time to time include yield  information in advertisements
or in  information  furnished  generally  to existing or proposed  shareholders.
Yield  information is computed in accordance with the SEC's  standardized  yield
formula.  The  calculation  for all  Classes is  computed  by  dividing  the net
investment  income per share of a Class during a base period of 30 days,  or one
month,  by the maximum  offering price per share of the applicable  Class of the
Fund on the last day of such base period.  The resulting  "30-day yield" is then
annualized as described  below.  Net  investment  income per share of a Class is
determined by dividing the Fund's net investment income  attributable to a Class
during  the base  period by the  average  number of shares of that  Class of the
Fund. The 30-day yield is then  "annualized" by a computation  that assumes that
the net  investment  income per share of a Class is earned and  reinvested for a
six-month  period at the same rate as during the 30-day base period and that the
resulting six-month income will be generated over an additional six months.

     The average  annual total  return (for a  designated  period of time) on an
investment  in the Fund may be  included in  advertisements,  and  furnished  to
existing or prospective  shareholders.  The average annual total return for each
Class is  computed  in  accordance  with the  SEC's  standardized  formula.  The
calculation for all Classes assumes the

                                       16

<PAGE>

reinvestment of all dividends and  distributions at net asset value and does not
reflect the impact of federal or state income  taxes.  In addition,  for Class A
shares the  calculation  assumes the  deduction  of the maximum  sales charge of
4.50%; for Class B and Class C shares the calculation  reflects the deduction of
any applicable  CDSC. The periods  illustrated  would normally include one, five
and ten years (or since the commencement of the public offering of the shares of
a Class, if shorter) through the most recent calendar quarter.

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

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

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

1.       INVESTMENT POLICIES AND RESTRICTIONS


         The  Fund's  Prospectus  presents  the  investment  objectives  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.  Capitalized terms not otherwise defined herein have the meaning given to
them in the Prospectus.

         The following  policies and  restrictions  set forth under  "Investment
Restrictions" supplement those discussed in the Prospectus.  Except with respect
to the policy on borrowing  described  below,  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, other than the policy on borrowing.


Lending of Portfolio Securities

         The Fund may lend portfolio  securities to member firms of the New York
Stock Exchange (the  "Exchange"),  under agreements which would require that the
loans be secured  continuously by collateral in cash, cash equivalents or United
States  ("U.S.")  Treasury  Bills  maintained on a current basis at an amount at
least  equal  to the  market  value of the  securities  loaned.  The Fund  would
continue to receive the  equivalent  of the  interest or  dividends  paid by the
issuer on the  securities  loaned and would also receive  compensation  based on
investment of the  collateral.  The Fund would not,  however,  have the right to
vote any  securities  having voting rights during the existence of the loan, but
would  call the loan in  anticipation  of an  important  vote to be taken  among
holders of the  securities or of the giving or withholding of their consent on a
material matter affecting the investment.

         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.  At no time would the value of
the  securities  loaned exceed 30% of the value of the Fund's total assets.  The
Fund did not lend  portfolio  securities  during the last fiscal year and has no
present intention to engage in any material securities lending in the future.

Mortgage-Backed Securities

Multiple-Class Pass-through Securities and Collateralized Mortgage Obligations

         The Fund may invest in collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduit ("REMIC")  pass-through or participation
certificates, which may be issued by, among others, U.S. Government agencies and
instrumentalities as well as private


                                      -2-
<PAGE>

lenders.  CMOs and REMIC  certificates  are issued in  multiple  classes and the
principal  of and interest on the  mortgage  assets may be  allocated  among the
several  classes of CMOs or REMIC  certificates  in various ways.  Each class of
CMOs or REMIC  certificates,  often  referred to as a "tranche,"  is issued at a
specific  adjustable  or fixed  interest rate and must be fully retired no later
than its final distribution date. Generally,  interest is paid or accrues on all
classes of CMOs or REMIC  certificates on a monthly basis.  Typically,  CMOs are
collateralized by certificates of the Government National Mortgage  Association,
the Federal  National  Mortgage  Association,  or the Federal Home Loan Mortgage
Corporation  but also may be  collateralized  by other  mortgage  assets such as
whole loans or private mortgage pass-through securities. Debt service on CMOs is
provided  from  payments of principal  and interest on  collateral  of mortgaged
assets and any reinvestment income thereon.

Risk Factors Associated with Mortgaged-Backed Securities

         The value of an investment in fixed rate obligations can be expected to
rise as interest  rates decline and decline as interest rates rise. In contrast,
as interest  rates on  adjustable  rate mortgage  loans are reset  periodically,
yields on investments in such loans will gradually  align  themselves to reflect
changes in market  interest  rates,  causing  the value of such  investments  to
fluctuate less dramatically in response to interest rate fluctuations than would
investments in fixed rate obligations.

         The yield characteristics of Mortgage-Backed  Securities, such as those
in which the Fund may invest,  differ  from those of  traditional  fixed  income
securities.  The major differences  typically include more frequent interest and
principal payments (usually  monthly),  the adjustability of interest rates, and
the possibility that prepayments of principal may be made substantially  earlier
than their final distribution dates.  Prepayment rates are influenced by changes
in current  interest  rates and a variety of  economic,  geographic,  social and
other  factors and cannot be predicted  with  certainty.  Both  adjustable  rate
mortgage loans and fixed rate mortgage loans may be subject to a greater rate of
principal  prepayment in a declining  interest rate  environment and to a lesser
rate of principal prepayments in an increasing interest rate environment.  Under
certain interest rate and prepayment rate scenarios, the Fund may fail to recoup
fully its investment in Mortgage-Backed Securities notwithstanding any direct or
indirect  governmental  or agency  guarantee.  When the Fund  reinvests  amounts
representing payments and unscheduled prepayments of principal, it may receive a
rate of  interest  that is  lower  than  the rate on  existing  adjustable  rate
mortgage  pass-through  securities.   Thus,   Mortgage-Backed   Securities,  and
adjustable  rate mortgage  pass-through  securities in  particular,  may be less
effective than other types of U.S. Government  securities as a means of "locking
in" interest rates.


Investment Restrictions

         Fundamental  Investment  Restrictions.  The  Fund has  adopted  certain
fundamental  investment  restrictions  which  may  not be  changed  without  the
affirmative vote of the holders of a majority of the Fund's  outstanding  voting
securities.  As  used  in  the  Prospectus  and  this  Statement  of  Additional
Information, such approval means the approval of the lesser of (i) the


                                      -3-
<PAGE>

holders of 67% or more of the shares  represented at a meeting if the holders of
more than 50% of the  outstanding  shares are present in person or by proxy,  or
(ii) the holders of more than 50% of the outstanding shares.

         The Fund may not:

                  (1)  purchase any security  (other than  securities  issued or
guaranteed  by the U.S.  Government  or its agencies or  instrumentalities)  if,
immediately  after and as a result of such  investment,  (a) more than 5% of the
value of the Fund's total assets would be invested in  securities of the issuer;
(b) the Fund would hold more than 10% of the voting securities of the issuer; or
(c) more than 25% of the  value of the  Fund's  assets  would be  invested  in a
single  industry  (each  of the  electric  utility,  natural  gas  utility,  and
telephone  industries  shall  be  considered  as a  separate  industry  for this
purpose);

                  (2) buy or sell  real  estate  in the  ordinary  course of its
business;  provided,  however,  the Fund may invest in readily  marketable  debt
securities  secured by real estate or interests  therein or issued by companies,
including  real  estate  investment  trusts,  which  invest  in real  estate  or
interests therein;

                  (3) buy or sell  commodities  or  commodity  contracts  except
interest rate futures  contracts,  options on  securities,  securities  indices,
currency and other  financial  instruments,  futures  contracts  on  securities,
securities indices, currency and other financial instruments and options on such
futures  contracts,   forward  foreign  currency  exchange  contracts,   forward
commitments,  securities index put or call warrants,  interest rate swaps,  caps
and floors and repurchase  agreements entered into in accordance with the Fund's
investment policies;

                  (4)  underwrite any issue of securities;

                  (5) make loans in an aggregate  amount in excess of 10% of the
value of the Fund's total assets,  taken at the time any loan is made,  provided
that (i) the  purchase  of debt  securities  pursuant  to the Fund's  investment
objectives shall not be deemed loans for the purposes of this restriction,  (ii)
loans of portfolio securities as described, from time to time, under "Lending of
Portfolio  Securities"  shall be made  only in  accordance  with the  terms  and
conditions  therein  set  forth and  (iii) in  seeking  a return on  temporarily
available cash, the Fund may engage in repurchase  transactions  maturing in one
week or less and involving  obligations of the U.S. Government,  its agencies or
instrumentalities;

                  (6) sell securities short,  except to the extent that the Fund
contemporaneously  owns  or has the  right  to  acquire  at no  additional  cost
securities identical to those sold short;

                  (7)  purchase securities on margin;

                  (8) borrow  money,  except  that,  as a temporary  measure for
extraordinary or emergency  purposes and not for investment  purposes,  the Fund
may  borrow  up to 5% of the  value  of its  total  assets  at the  time  of the
borrowing; or

                                      -4-
<PAGE>

                  (9)  mortgage, pledge, or hypothecate any of its assets.

         Non-fundamental  Investment  Restrictions.  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) invest in companies for the purpose of exercising  control
or management;

                  (2)  knowingly   purchase   securities  of  other   registered
investment  companies,  except  in  connection  with  a  merger,  consolidation,
acquisition, or reorganization;

                  (3) invest in any security, including any repurchase agreement
maturing in more than seven  days,  which is  illiquid,  if more than 15% of the
total  assets of the Fund,  taken at market  value,  would be  invested  in such
securities;

                  (4) purchase or retain the securities of any issuer,  if those
individual  officers  and  trustees  or  directors  of the Fund,  its adviser or
principal underwriter,  each owning beneficially more than one half of 1% of the
securities of such issuer,  together own more than 5% of the  securities of such
issuer; or

                  (5) invest more than 5% of its total assets in  securities  of
companies having, together with their predecessors,  a record of less than three
years of continuous operation.

         It is the  policy of the Fund not to  concentrate  its  investments  in
securities of companies in any particular  industry or group of  industries.  In
the opinion of the staff of the Securities and Exchange  Commission (the "SEC"),
investments  are  concentrated  in a  particular  industry  if such  investments
aggregate 25% or more of the Fund's total  assets.  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.

         In connection with the offering of its shares in various  states,  as a
matter of  non-fundamental  investment policy, the Fund has agreed not to invest
in puts, calls,  straddles,  spreads or any combination  thereof, in oil, gas or
other mineral  leases,  exploration or development  programs,  or in real estate
limited partnerships.

Other Policies and Risks

         The Fund may invest up to 15% of its assets in foreign  securities  and
up to 5% of  its  assets  in  foreign  securities  which  are  not  listed  on a
recognized  foreign or domestic  exchange,  provided that  purchases of Canadian
securities are not subject to the  limitations in this  paragraph.  Investing in
securities of foreign  companies and countries  involves certain  considerations
and risks which are not typically  associated with investing in U.S.  government
securities and those of


                                      -5-
<PAGE>

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.

         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 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.  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.

2.       MANAGEMENT OF THE FUND

         The  Fund's  Board of  Trustees  provides  broad  supervision  over the
affairs of the Fund.  The  officers of the Fund are  responsible  for the Fund's
operations.  The Trustees and  executive  officers of the Fund are listed below,
together  with  their  principal  occupations  during  the past five  years.  An
asterisk  indicates those Trustees who are interested persons of the Fund within
the meaning of the Investment Company Act of 1940, as amended (the "1940 Act").

3.       INVESTMENT ADVISER

         The  Fund  has   contracted   with  PMC,  60  State   Street,   Boston,
Massachusetts, to act as its investment adviser. The term of the contract is one
year, but it is renewable  annually after such date by the vote of a majority of
the Board of Trustees of the Fund (including a majority of the Board of Trustees
who are not parties to the contract or  interested  persons of any such parties)
cast in person at a meeting  called for the  purpose of voting on such  renewal.
This contract  terminates if assigned and may be terminated  without  penalty by
either  party by vote of its  Board of  Directors  or  Trustees  or by vote of a
majority of outstanding  voting securities and the giving of sixty days' written
notice.  Pursuant  to the  management  contract,  PMC 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
securities on the recommendation of PMC. PMC, however,  is not protected against
liability by reason of wilful 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 the respective management contract.


         As compensation for its management services and expenses incurred,  PMC
is  entitled  to a  management  fee at the rate of 0.50% per annum of the Fund's
average daily net assets.  The fee is normally  computed daily and paid monthly.
During  its  1996,  1995 and 1994  fiscal  years,  the Fund  paid or owed  total
management  fees  to PMC  of  approximately  $588,432,  $546,000  and  $571,000,
respectively.


 4.      UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

         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.  The  Underwriting  Agreement  provides  that PFD  will  bear any
distribution expenses not borne by the Fund.

         PFD  bears all  expenses  it incurs  in  providing  services  under the
Underwriting Agreement.  Such expenses include compensation to its employees and
representatives  and to securities  dealers for  distribution  related  services
performed for the Fund.  PFD also pays certain  expenses in connection  with the
distribution of the Fund's shares, including the cost of preparing, printing and
distributing  advertising or promotional materials, and the cost of printing and
distributing prospectuses and supplements to prospective shareholders.  The Fund
bears the cost of registering its shares under federal and state securities law.
The  Fund  and  PFD  have  agreed  to  indemnify  each  other  against   certain
liabilities, including liabilities under the Securities Act of 1933, as amended.
Under the  Underwriting  Agreement,  PFD will use its best  efforts in rendering
services to the Fund.


         The Fund has  adopted a plan of  distribution  pursuant  to Rule  12b-1
under the 1940 Act with  respect  to Class A,  Class B and  Class C shares  (the
"Class A  Plan,"  the  "Class B Plan"  and the  "Class C Plan")  (together,  the
"Plans").


                                      -11-
<PAGE>

         Class A Plan

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

         Class B Plan

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

   
         The purpose of  distribution  payments to PFD under the Class B Plan is
to  compensate  PFD  for  its  distribution  services  to  the  Fund.  PFD  pays
commissions to dealers as well as expenses of printing  prospectuses and reports
used for sales  purposes,  expenses with respect to the preparation and printing
of sales literature and other distribution related expenses,  including, without
limitation,  the cost necessary to provide  distribution-  related services,  or
personnel,  travel office expenses and equipment. The Class B Plan also provides
that  PFD  will  receive  all  CDSC's  attributable  to  Class  B  shares.  (See
"Distributions  Plans" in the  Prospectus.)  When a broker-dealer  sells Class B
shares and  elects,  with  PFD's  approval,  to waive its right to  receive  the
commission  normally paid at the time of the sale,PFD may cause all or a portion
of the distribution fees described above to be paid to the broker-dealer.
    



Class C Plan

         The  Class C Plan  provides  that a Fund  will pay PFD,  as the  Fund's
distributor  for its Class C shares,  a distribution  fee accrued daily and paid
quarterly,  equal on an annual  basis to 0.75% of the Fund's  average  daily net
assets  attributable  to Class C shares and will pay PFD a service  fee equal to
0.25% of the Fund's average daily net assets attributable to Class C shares. PFD
will in turn pay to securities dealers which enter into a sales agreement with



                                      -12-
<PAGE>


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

   
         The purpose of  distribution  payments to PFD under the Class C Plan is
to  compensate  PFD for its  distribution  services  with respect to the Class C
shares of the Fund.  PFD pays  commissions  to  dealers as well as  expenses  of
printing prospectuses and reports used for sales purposes, expenses with respect
to   the   preparation   and   printing   of   sales    literature   and   other
distribution-related expenses, including, without limitation, the cost necessary
to provide  distribution-related  services, or personnel, travel office expenses
and  equipment.  The Class C Plan also  provides that PFD will receive all CDSCs
attributable to Class C shares.  (See  "Distribution  Plans" in the Prospectus.)
When a broker-dealer  sells Class C shares and elects,  with PFD's approval,  to
waive its right to receive the commission normally paid at the time of the sale,
PFD may cause all or a portion of the  distribution  fees described  above to be
paid to the broker-dealer.     



         General

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

         No  interested  person of the Fund,  nor any Trustee of the Fund who is
not an  interested  person of the Fund,  has any  direct or  indirect  financial
interest in the operation of the Plans except to the extent that PFD and certain
of its employees may be deemed to have such an interest as a result of receiving
a portion of the amounts  expended under the Plans by the Fund and except to the
extent certain officers may have an interest in PFD's ultimate parent, PGI.

         The Plans were  adopted by a  majority  vote of the Board of  Trustees,
including  all of the Trustees who are not, and were not at the time they voted,
interested  persons of the Fund, as defined in the 1940 Act (none of whom had or
have any direct or indirect  financial  interest in the operation of the Plans),
cast in person at a meeting  called for the  purpose of voting on the Plans.  In
approving  the  Plans,  the  Trustees  identified  and  considered  a number  of
potential  benefits which the Plans may provide.  The Board of Trustees believes
that there is a reasonable


                                      -13-
<PAGE>

likelihood  that the Plans  will  benefit  the Fund and its  current  and future
shareholders.  Under their  terms,  the Plans remain in effect from year to year
provided such  continuance  is approved  annually by vote of the Trustees in the
manner described above. The Plans may not be amended to increase  materially the
annual  percentage  limitation  of average net assets which may be spent for the
services  described  therein  without  approval of the  shareholders of the Fund
affected thereby,  and material amendments of the Plans must also be approved by
the Trustees in the manner  described  above.  A Plan may be  terminated  at any
time,  without  payment of any penalty,  by vote of the majority of the Trustees
who are not  interested  persons  of the  Fund and have no  direct  or  indirect
financial  interest in the operations of the Plan, or by a vote of a majority of
the  outstanding  voting  securities  of the  respective  Class  of the Fund (as
defined in the 1940 Act).  A Plan will  automatically  terminate in the event of
its assignment (as defined in the 1940 Act).


         During the fiscal  year ended June  30,1996,  the Fund  incurred  total
distribution fees pursuant to the Fund's Class A Plan, Class B Plan, and Class C
Plan  respectively,  as follows:  $248,056,  $119,908 and $789. The distribution
fees  were  paid by the Fund to PFD in  reimbursement  of  expenses  related  to
servicing  of  shareholder  accounts  and  to  compensating  dealers  and  sales
personnel.

         Upon  redemption,  Class A shares may be subject to a 1% CDSC,  Class B
shares  are  subject to a CDSC at a rate  declining  from a maximum of 4% of the
lower of the cost or market  value of the shares and Class C shares are  subject
to a 1% CDSC.  During the fiscal year ended June 30, 1996,  CDSCs, in the amount
of  approximately  $34,000 were paid to PFD in reimbursement of expenses related
to servicing of  shareholders'  accounts  and  compensation  paid to dealers and
sales personnel.


5.       SHAREHOLDER SERVICING/TRANSFER AGENT

         The  Fund  has   contracted   with  PSC,  60  State   Street,   Boston,
Massachusetts  02109,  to act as shareholder  servicing agent and transfer agent
for the Fund. This contract terminates if assigned and may be terminated without
penalty  by either  party by vote of its Board of  Directors  or  Trustees  or a
majority of its  outstanding  voting  securities  and the giving of ninety days'
written notice.

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


   
         PSC  receives  an annual  fee of $28.00  for each  Class A, Class B and
Class C  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.
The  Fund  may  compensate   entities  which  have  agreed  to  provide  certain
sub-accounting   services,   such  as  specific   transaction   processing   and
recordkeeping  services.  Any such  payments by the Fund would be in lieu of the
per account fee which would otherwise be paid by the Fund to PSC.
    


                                      -14-
<PAGE>

would otherwise be paid by the Fund to PSC.

6.       CUSTODIAN

         Brown  Brothers  Harriman & Co.  (the  "Custodian"),  40 Water  Street,
Boston,  Massachusetts  02109,  is the  custodian  of  the  Fund's  assets.  The
Custodian's responsibilities include safekeeping and controlling the Fund's cash
and securities,  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.

7.       PRINCIPAL UNDERWRITER


         PFD,  60 State  Street,  Boston,  Massachusetts  02109,  serves  as the
principal underwriter for the Fund. During the Fund's 1996, 1995 and 1994 fiscal
years,  net  underwriting  commissions  earned  by PFD in  connection  with  its
offering  of Fund  shares  were  approximately  $39,000,  $39,000  and  $66,000,
respectively.  Commissions reallowed to dealers by PFD in those three years were
approximately $281,000, $268,000 and $492,000,  respectively.  See "Underwriting
Agreement and  Distribution  Plan" above for a  description  of the terms of the
Underwriting Agreement with PFD.


         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;  (ii) 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.

8.       INDEPENDENT PUBLIC ACCOUNTANTS

   
         Arthur Andersen LLP, 225 Franklin Street, Boston,  Massachusetts 02110,
are 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 SEC.     

9.       PORTFOLIO TRANSACTIONS

         All orders for the purchase or sale of portfolio  securities are placed
on behalf of the Fund


                                      -15-
<PAGE>

by PMC pursuant to authority  contained in the management  contract.  Securities
purchased and sold on behalf of the Fund normally will be traded in the over-the
counter market on a net basis (i.e. without  commission)  through dealers acting
for their own  account  and not as brokers  or  otherwise  through  transactions
directly with the issuer of the  instrument.  Some  securities are purchased and
sold on an exchange or in over-the-counter  transactions  conducted on an agency
basis involving a commission.  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; the
reasonableness  of any dealer  spreads;  and the dealer's  sale of shares of the
Fund or other Pioneer mutual funds.

         PMC may select dealers which provide brokerage and/or research services
to the Fund and/or other investment  companies  managed by PMC.  Consistent with
Section 28(e) of the Securities  Exchange Act of 1934, as amended,  the Fund may
pay  commissions  to such  broker-dealers  in an amount  greater than the amount
another firm might charge as compensation for such services if PMC determines in
good faith  that the amount of the  commissions  charged by a  broker-dealer  is
reasonable  in relation to the  services  provided by such  broker-dealer.  Such
services may include advice concerning the value of securities; the advisability
of  investing  in,  purchasing  or  selling  securities;   the  availability  of
securities or the  purchasers or sellers of  securities;  providing  stock price
quotation services; furnishing analyses, 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 broker-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  broker-dealers  (including
broker-dealers  on the  listing)  without  regard  to  the  furnishing  of  such
services,  it is not possible to estimate the  proportion  of such  transactions
directed to such broker-  dealers  solely  because such services were  provided.
Management  believes  that no exact  dollar  value  can be  calculated  for such
services.

         The  research  received  from dealers may be useful to PMC in rendering
investment  management  services  to the Fund  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.

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


                                      -16-
<PAGE>

shares of the Fund.

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

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

         It is possible  that, at times,  identical  securities  will be held by
more than one fund and/or account.  However, the position of any fund or account
in the same issue may vary and the  length of time that any fund or account  may
choose to hold its investment in the same issue may likewise vary. To the extent
that the Fund,  another  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 other account.  In the event that more
than one account  purchases  or sells the same  security  on a given  date,  the
purchases and sales will normally be made as nearly as practicable on a pro rata
basis in proportion to the amounts desired to be purchased or sold by each.
   
10. 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.  These  requirements  relate to the  sources  of the Fund's
income, the  diversification of its assets and the distribution of its income to
shareholders.  If the Fund meets all such  requirements  and  distributes to its
shareholders, in accordance with the Code's timing requirements,  all investment
company  taxable income and net capital gain, if any,  which it earns,  the Fund
will be relieved of the necessity of paying federal income tax.

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

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

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

Foreign  exchange  gains and  losses  realized  by the Fund in  connection  with
certain  transactions  involving foreign  currency-denominated  debt securities,
foreign currencies, or payables or receivables denominated in a foreign currency
are subject to Section 988 of the Code,  which  generally  causes such gains and
losses to be treated as  ordinary  income and losses and may affect the  amount,
timing and character of  distributions  to  shareholders.  Any  transactions  in
foreign  currency  that are not directly  related to the Fund's  investments  in
securities  may need to be limited  in order to enable  the Fund to satisfy  the
limitations  described in the second  paragraph above that are applicable to the
income or gains recognized by a regulated investment company. If the net foreign
exchange loss for a year were to exceed the Fund's  investment  company  taxable
income (computed  without regard to such loss), the resulting  ordinary loss for
such year  would not be  deductible  by the Fund or its  shareholders  in future
years.

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

For federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss for any year to offset its capital gains,  if any, during the eight
years following the year of the loss. To the extent subsequent capital gains are
offset by such losses,  they would not result in federal income tax liability to
the  Fund  and  therefore  are  not  expected  to  be  distributed  as  such  to
shareholders.   At  June  30,  1996,   the  Fund  had  aggregate   capital  loss
carryforwards  of approximately  $3,200,964,  which will expire between 1998 and
2004 if not utilized

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

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

In addition,  if Class A shares  redeemed or  exchanged  have been held for less
than 91 days, (1) in the case of a  reinvestment  at net asset value pursuant to
the reinvestment privilege, the sales charge paid on such shares is not included
in their tax basis under the Code, and (2) in the case of an exchange,  all or a
portion of the sales  charge  paid on such  shares is not  included in their tax
basis under the Code, to the extent a sales charge that would otherwise apply to

<PAGE>

the shares  received is reduced  pursuant to the exchange  privilege.  In either
case,  the  portion  of the sales  charge not  included  in the tax basis of the
shares  redeemed or  surrendered  in an exchange is included in the tax basis of
the shares acquired in the  reinvestment  or exchange.  Losses on redemptions or
other  dispositions  of shares may be disallowed  under "wash sale" rules in the
event of other  investments  in the  Fund  (including  those  made  pursuant  to
reinvestment of dividends and/or capital gain distributions)  within a period of
61 days  beginning 30 days before and ending 30 days after a redemption or other
disposition of shares. In such a case, the disallowed  portion of any loss would
be  included  in the  federal  tax  basis of the  shares  acquired  in the other
investments.

The   Fund's   dividends   and   distributions   will   not   qualify   for  any
dividends-received  deduction  that might  otherwise  be  available  for certain
dividends received by shareholders that are corporations.

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

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

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is  generally  available  to the extent the Fund's  distributions  are
derived from  interest on (or, in the case of  intangible  property  taxes,  the
value of its assets is  attributable  to) certain U.S.  Government  obligations,
provided in some states that certain thresholds for holdings of such obligations
and/or reporting  requirements are satisfied.  The Fund will not seek to satisfy
any  threshold or reporting  requirements  that may apply in  particular  taxing
jurisdictions,  although the Fund may in its sole  discretion  provide  relevant
information to shareholders.

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

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

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

    


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.  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
in the Fund.  The  Declaration  of Trust  further  authorizes  the  Trustees  to
classify  or  reclassify  any  series of the  shares  into one or more  classes.
Pursuant thereto,  the Trustees have authorized the issuance of three classes of
shares of the  Fund,  Class A shares,  Class B shares  and Class C shares.  Each
share of a class of the Fund represents an equal  proportionate  interest in the
assets  of the Fund  allocable  to that  class.  Upon  liquidation  of the Fund,
shareholders  of each  class are  entitled  to share pro rata in the  Fund's net
assets allocable to such class available for  distribution to shareholders.  The
Fund  reserves  the right to create  and issue  additional  series or classes of
shares,  in which case the shares of each  class of a series  would  participate
equally in the  earnings,  dividends  and assets  allocable to that class of the
particular series.


         The  shares of the Fund are  entitled  to vote  separately  to  approve
investment  advisory  agreements  or changes  in  investment  restrictions,  but
shareholders  of all series  vote  together in the  election  and  selection  of
Trustees and accountants. Shares of the Fund vote together as a class on matters
that affect the Fund in substantially the same manner. As to matters affecting a
single class, shares of such class will vote separately.

         Although  Trustees  are  not  elected  annually  by  the  shareholders,
shareholders  have under certain  circumstances  the right to remove one or more
Trustees.  No amendment that adversely affects 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 except
that under certain  circumstances  Class B shares may convert to Class A shares.
Shares are fully paid and non-assessable by the Fund, except as set forth below.
See "Certain Liabilities."

12.      CERTAIN LIABILITIES

         As a Massachusetts  business trust, the Fund's  operations are governed
by its  Declaration  of Trust dated December 7, 1993, a copy of which is on file
with the office of the Secretary of State of The Commonwealth of  Massachusetts.
Theoretically, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held  personally  liable  for the  obligations  of the trust.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability  for acts or  obligations  of the Fund or any  series  of the Fund and
provides that notice of such disclaimer be given in each  agreement,  obligation
or instrument entered into or executed by


                                      -20-
<PAGE>

the Fund or its Trustees.  Moreover,  the  Declaration of Trust 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.  The  Declaration of
Trust also 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
would be limited to  circumstances  in which the Fund  itself  will be unable to
meet its  obligations.  In light of the  nature of the Fund's  business  and the
nature and  amount of its  assets,  the  possibility  of the Fund's  liabilities
exceeding its assets, and therefore a shareholder's risk of personal  liability,
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 each class of the Fund is  determined
as of the close of regular trading on the Exchange (currently 4:00 p.m., Eastern
Time) on each day on which the Exchange is open for  trading.  As of the date of
this Statement of Additional Information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Presidents' Day, Good
Friday,  Memorial  Day,  Independence  Day,  Labor  Day,  Thanksgiving  Day  and
Christmas  Day.  The net asset value per share of each class of the Fund is also
determined  on any  other day in which the  level of  trading  in its  portfolio
securities  is  sufficiently  high so that the current net asset value per share
might  be  materially  affected  by  changes  in  the  value  of  its  portfolio
securities.  On any day in which no  purchase  orders for the shares of the Fund
become effective and no shares are tendered for redemption,  the net asset value
per share is not required to be determined.

         The net asset  value per share of each class of the Fund is computed by
taking the value of all of its assets, less the Fund's liabilities, attributable
to the class, and dividing it by the number of outstanding  shares of the class.
The Board of Trustees  has  directed  that the fair  market  value of the Fund's
assets  should  be  determined  as  follows.  Ordinarily,  investments  in  debt
securities are valued on the basis of information furnished by a pricing service
which  utilizes  primarily  a matrix  system  (which  reflects  such  factors as
security  prices,  yields,  maturities and ratings),  supplemented by dealer and
exchange  quotations,  to recommend  valuations  for normal  institutional-sized
trading units of debt securities. In addition, the Board has instructed advisory
personnel  not to rely  exclusively  on this pricing  service if the fair market
value of certain  securities may be more  accurately  determined on the basis of
information available from other sources.  Temporary cash investments are valued
at cost, which approximates market value.

                                      -21-
<PAGE>


         The Fund's  maximum  offering  price per Class A share is determined by
adding the maximum sales charge to the net asset value per Class A share.  Class
B and Class C shares are offered at net asset value without the imposition of an
initial sales charge.


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.  The  applicant  must
deposit or purchase for deposit with PSC shares of the Fund having a total value
of not less than $10,000.  Withdrawals  from Class B and Class C share  accounts
are  limited  to  10% of the  value  of the  account  at  the  time  the  SWP is
implemented.  Periodic  checks of $50 or more will be sent to the applicant,  or
any person designated by him, monthly or quarterly.

         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.  Share redemptions are taxable transactions,  and
in addition the amounts  received by a  shareholder  cannot be  considered as an
actual yield or income on his or her  investment  because part of such  payments
may be a return of his or her investment.

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

   
15.      LETTER OF INTENT (Class A only)


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

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

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

16.      INVESTMENT RESULTS

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

Quotations, Comparisons, and General Information

         From  time to  time,  in  advertisements,  in sales  literature,  or in
reports to  shareholders,  the past  performance  of the Fund may be illustrated
and/or  compared  with  that of  other  mutual  funds  with  similar  investment
objectives,  and to other relevant indices.  For example, the Fund may compare a
class's  yield  and/or total return to the  Shearson  Lehman  Hutton  Government
Index,  U.S.  Government bond rates, or other  comparable  indices or investment
vehicles.

         In addition, the performance of the classes of the Fund may be compared
to alternative investment or savings vehicles and/or to indices 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 Barron's,  Business Week, Consumers Digest, Consumer Reports,  Financial
World, Forbes, Fortune,  Investors Business Daily,  Kiplinger's Personal Finance
Magazine,  Money Magazine,  New York Times, Personal Investor,  Smart Money, USA
Today, U.S. News and World Report,  The Wall Street Journal,  and Worth may also
be cited (if the Fund is listed in such publications) or used for comparison, as
well as performance  listings and rankings from various other sources  including
CDA/Weisenberger  Investment Companies Service,  Donoghue's Mutual Fund Almanac,
Investment  Company Data, Inc.,  Ibbotson  Associates,  Johnson's Charts,  Kanon
Block Carre and Co., Lipper Analytical Services,  Micropal,  Inc.,  Morningstar,
Inc., Schabacker Investment Management and Towers Data Systems, Inc.

         In addition,  from time to time quotations from articles from financial
publications such as those listed above may be used in advertisements,  in sales
literature or in reports to Fund shareholders.

         One of the primary  methods used to measure the  performance of a class
of the Fund is "total  return."  "Total  return"  will  normally  represent  the
percentage change in value of an account, or of a hypothetical investment in the
class,  over  any  period  up  to  the  lifetime  of  the  class.  Total  return
calculations will usually assume the reinvestment of all dividends and capital

                                      -23-
<PAGE>

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 may be  accompanied  by total return  percentages  for each
year within the period and/or by the average annual  compounded total return for
the period. The income and capital components of a given return may be separated
and  portrayed  in a  variety  of ways in order  to  illustrate  their  relative
significance.  Performance  may also be portrayed in terms of cash or investment
values,  without  percentages.  Past performance cannot guarantee any particular
future result.

         In  representing  investment  results  of a  class,  the  Fund may also
include  references to certain  financial  planning  concepts,  including (a) an
investor's  need to evaluate  his or her  financial  assets and  obligations  to
determine how much to invest;  (b) the need to analyze the objectives of various
investments to determine where to invest; and (c) the need to analyze his or her
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.

Standardized Yield Quotations

         The yield of a class is computed by dividing the class's net investment
income per share during a base period of 30 days,  or one month,  by the maximum
offering  price per  share of the  class on the last day of such base  period in
accordance with the following formula:

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

Where:            a          =      interest earned during the period

                  b          =      net expenses accrued for the period

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

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

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

         (i) The  yield  to  maturity  of each  obligation  held by the  Fund is
computed based on the market value of the obligation  (including  actual accrued
interest,  if any) at the close of  business  each day during  the  30-day  base
period, or, with respect to obligations purchased during the month, the purchase
price (plus  actual  accrued  interest,  if any) on  settlement  date,  and with
respect to obligations sold during the month the sale price (plus actual accrued
interest, if any) between the trade and settlement dates.

                                      -24-
<PAGE>

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

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

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

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

         For purposes of  computing  yield,  interest  income is  recognized  by
accruing  1/360 of the stated  interest  rate of each  obligation  in the Fund's
portfolio each day that the obligation is in the portfolio.  Expenses of a class
accrued during any base period, if any, pursuant to the respective  Distribution
Plan are included among the expenses accrued during the base period.


         The Fund's yield for the 30 days ended June 30, 1996, computed as above
was 5.84% for  Class A  shares,  5.15% for Class B shares  and 5.27% for Class C
shares.


Standardized Average Annual Total Return Quotations

         The average  annual  total return  quotations  for a class of shares is
computed  by finding  the average  annual  compounded  rate of return that would
cause  a  hypothetical  investment  in the  class  made  on the  first  day of a
designated  period (assuming all dividends and  distributions are reinvested) to
equal the ending  redeemable value of such  hypothetical  investment on the last
day of the designated period in accordance with the following formula:

                P(1+T)n  =   ERV


       Where:            P       =        a  hypothetical   initial  payment  of
                                          $1000,  less the maximum sales load of
                                          $45  for   Class  A   shares   or  the
                                          deduction  of the  CDSC on  Class B or
                                          Class C shares at the end of the
                                          period.


                         T       =        average annual total return

                                      -25-
<PAGE>

                         n       =        number of years

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

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


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

The total returns for each Class of shares of the Fund as of June 30, 1996,  are
as follows:

                         Average Annual Total Return (%)
                           One Year   Five Years     Ten Years  Since Inception*
Class A Shares              -0.66        6.86           7.34         8.90
Class B Shares              -0.73         N/A           N/A          4.46
Class C Shares               N/A          N/A           N/A         -3.95

* Inception  was October 31, 1978 for Class A shares and April 4, 1994 for Class
B shares. Class C Shares were first offered January 31, 1996.

                                   APPENDIX A


                          Description of Bond Ratings1


                        Moody's Investors Service, Inc.2


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

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

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

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

- ---------------------------------------------
1 The  ratings  indicated  herein are  believed  to be the most  recent  ratings
available at the date of this Prospectus for the securities listed.  Ratings are
generally given to securities at the time of issuance. While the rating agencies
may from time to time revise such  ratings,  they  undertake no obligation to do
so, and the ratings indicated do not necessarily represent ratings which will be
given to these securities on the date of the Fund's fiscal year-end.

2 Rates bonds of issuers  which have  $600,000 or more of debt,  except bonds of
educational  institutions,  projects  under  construction,  enterprises  without
established  earnings  records and  situations  where current  financial data is
unavailable.



                                      -28-
<PAGE>



                        Standard & Poor's Ratings Group 3

AAA:  Bonds rated AAA are highest grade  obligations.  This rating  indicates an
extremely strong capacity to pay principal and interest.

AA: Bonds rated AA also  qualify as  high-quality  obligations.  Capacity to pay
principal  and  interest is very strong,  and in the majority of instances  they
differ from AAA issues only in small degree.

A: Bonds rated A have a strong capacity to pay principal and interest,  although
they are more susceptible to the adverse effects of changes in circumstances and
economic conditions.

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

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

                             COMPARATIVE PERFORMANCE
                               INDEX DESCRIPTIONS

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

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

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

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

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

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

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

minus the current  date.  The bond was "held" for the calendar  year and returns
were  computed.  Total returns for 1977-1991 are calculated as the change in the
flat price or and-interest price.

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

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

MSCI
Morgan  Stanley  Capital  International   Indices,   developed  by  the  Capital
International  S.A., are based on share prices of some 1470 companies  listed on
the stock exchanges around the world.

Countries in the MSCI EAFE Portfolio are:
Australia;  Austria;  Belgium;  Denmark;  Finland;  France;  Germany; Hong Kong;
Italy;  Japan;  Netherlands;  N.  Zealand;  Norway;  Singapore/Malaysia;  Spain;
Sweden; Switzerland; United Kingdom.

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

LONG-TERM U.S. CORPORATE BONDS
For  1969-1991,  corporate  bond total  returns are  represented  by the Salomon
Brothers Long-Term  High-Grade  Corporate Bond Index. Since most large corporate
bond  transactions  take place over the  counter,  a major dealer is the natural
source of these data. The index includes  nearly all Aaa- and Aa-rated bonds. If
a bond is  downgraded  during a  particular  month,  its return for the month is
included in the index before removing the bond from future portfolios.

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

Mirror/Mosby, St. Louis, 1990, p. 97 ["Level-Coupon Bonds"].) The monthly income
return was assumed to be one-twelfth the coupon.

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

NAREIT-EQUITY INDEX
All of the  data is  based  upon the last  closing  price of the  month  for all
tax-qualified  REITs  listed  on the  NYSE,  AMSE  and the  NASDAQ.  The data is
market-value-weighted.  Prior to 1987 REITs were added to the index the  January
following  their  listing.  Since 1987 Newly formed or listed REITs are added to
the total  shares  outstanding  figure in the month that the shares are  issued.
Only  common  shares  issued by the REIT are  included  in the index.  The total
return  calculation  is based upon the weighing at the  beginning of the period.
Only  those  REITs  listed for the  entire  period are used in the total  return
calculation.  Dividends are included in the month based upon their payment date.
There is no smoothing of income. Liquidating dividends, whether full or partial,
are treated as income.

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

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

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

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

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

BANK SAVINGS ACCOUNT
Data sources include the U.S. League of Savings Institutions Sourcebook; average
annual yield on savings  deposits in FSLIC [FDIC] insured  savings  institutions
for the years 1963-1987 and The Wall Street Journal for the years 1988-1994.
