Pioneer
Micro-Cap
Fund

   
Class A and Class B Shares
Prospectus
August 29, 1997
    
 
      Pioneer Micro-Cap Fund (the "Fund") seeks capital appreciation by
investing in a diversified portfolio of securities consisting primarily of
common stocks. Any current income generated from these securities is incidental
to the investment objective of the Fund.

      In seeking to achieve its investment objective, the Fund will invest at
least 80% of its total assets in common stocks and common stock equivalents
(such as convertible bonds and preferred stock) of companies with a market
capitalization of $300 million or less. See "Investment Objective and Policies"
in this Prospectus. There is no assurance that the Fund will achieve its
investment objective.

      Prospective investors should be aware that management intends to close the
Fund to new investments after the Fund reaches $150 million in total assets.
Management reserves the right to modify or eliminate restrictions on the sale of
Fund shares. A number of factors will be considered in making such decisions
including, but not limited to, total assets under management. See "How to Buy
Fund Shares--Special Restrictions" for more information.

      Fund returns and share prices fluctuate and the value of your account upon
redemption may be more or less than your purchase price. Shares in the Fund are
not deposits or obligations of, or guaranteed or endorsed by, any bank or other
depository institution, and the shares are not federally insured by the Federal
Deposit Insurance Corporation, the Federal Reserve Board or any other government
agency. Investments in the securities of micro-capitalization ("micro-cap")
companies may offer greater capital appreciation potential than investments in
securities of larger companies, but may be subject to greater short-term price
fluctuations. The Fund is intended for investors who can accept the risks
associated with its investments and may not be suitable for all investors. See
"Investment Objectives and Policies" for a discussion of these risks.

   
      This Prospectus provides information about the Fund that you should know
before investing. Please read and retain it for future reference. More
information about the Fund is included in the Statement of Additional
Information, also dated August 29, 1997, which is incorporated into this
Prospectus by reference. A copy of the Statement of Additional Information may
be obtained free of charge by calling Shareholder Services at 1-800-225-6292 or
by written request to the Fund at 60 State Street, Boston, Massachusetts 02109.
Additional information about the Fund has been filed with the Securities and
Exchange Commission (the "SEC") and is available upon request and without
charge.

I. EXPENSE INFORMATION
     This table is designed to help you understand the charges and expenses
that you, as a shareholder, will bear directly or indirectly when you invest in
the Fund. The table reflects shareholder transaction and annual operating
expenses. "Other Expenses" are based on estimates for the fiscal period ending
November 30, 1997.

(1) Separate fees (currently $10 and $20, respectively) apply to domestic and
    international wire transfers of redemption proceeds.
   
(2) Pioneering Management Corporation ("PMC") has agreed not to impose all or a
    portion of its management fee and to make other arrangements, if necessary,
    to limit the operating expenses of the Class A shares of the Fund to 1.75%
    of the average daily net assets attributable to the Class A shares; the
    portion of fund-wide expenses attributable to Class B shares will be
    reduced only to the extent they are reduced for Class A shares. This
    agreement is voluntary and temporary and may be revised or terminated at
    any time. The agreement is expected to remain in effect for the current
    fiscal year.

(3) This is the maximum annual fee rate and assumes that the Plan of 
    Distribution is in effect for an entire year; actual expenses are expected
    to be lower.
    
 Example:

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

- --Assuming no redemption    ............    $24         $ 74
</TABLE>

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

      THE EXAMPLE IS DESIGNED FOR INFORMATION PURPOSES ONLY, AND SHOULD NOT BE
CONSIDERED A REPRESENTATION OF FUTURE EXPENSES OR RETURN. ACTUAL FUND EXPENSES
AND RETURN WILL 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 Rule 12b-1 fee may result in long-term
shareholders 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
larger amounts of Class A shares and the value of shares owned in other Pioneer
mutual funds is taken into account in determining the applicable initial sales
charge. See "How to Buy Fund Shares." No sales charge is applied to exchanges of
shares of the Fund for shares of other publicly available Pioneer mutual funds.
See "How to Exchange Shares."

III. INVESTMENT OBJECTIVE AND POLICIES
      The investment objective of the Fund is to seek capital appreciation by
investing in a diversified portfolio of securities consisting primarily of
common stocks. Any current income produced by a security is not a primary factor
in the selection of investments.

      Under normal circumstances, at least 80% of the Fund's total assets are
invested in common stocks and common stock equivalents of companies with a
market capitalization of $300 million or less determined at the time the
security is purchased ("micro-cap companies"). The typical capitalization of
issuers of securities purchased by the Fund is expected to be approximately $100
million. While micro-cap company securities may offer a greater capital
appreciation potential than investments in securities of larger companies, they
may also present greater risks. Micro-cap companies may have limited product
lines, market and financial resources, or may be dependent on small or less
experienced management groups. In addition, the trading volume of micro-cap
companies may be limited. Historically, the market price for securities of
micro-cap companies has been more volatile than for securities of companies with
greater capitalization.

      The Fund is managed in accordance with the value investment philosophy of
PMC, the investment adviser to the Fund. This approach consists of developing a
diversified portfolio of securities consistent with the Fund's investment
objective and selected primarily on the basis of PMC's judgment that the
securities have an underlying value, or potential value, which exceeds their
current prices. The analysis and quantification of the economic worth, or basic
value, of individual companies reflects PMC's assessment of a company's assets
and the company's prospects for earnings growth over the next 1-1/2-to-3 years.
PMC relies primarily on the knowledge, experience and judgment of its own
research staff, but also receives and uses information from a variety of outside
sources, including brokerage firms, electronic data bases, specialized research
firms and technical journals.

      The Fund's investments in common stocks may include common stock
equivalents, that is, securities with common stock characteristics such as
convertible bonds and preferred stocks. The Fund may invest in the securities of
real estate investment trusts ("REITs"). While there is no requirement to do so,
the Fund currently intends to limit its investments in REITs to 15% of total
assets. For more information on REITs see the Appendix.

      The Fund intends to be substantially fully invested at all times. If
suitable investments are not immediately available, the Fund may hold a portion
of its investments in cash and cash-equivalents. For temporary defensive
purposes, however, the Fund may invest up to 100% of its assets in short-term
investments. The Fund will assume a defensive posture only when political and
economic factors affect common stock markets to such an extent that PMC believes
there to be extraordinary risks in being substantially invested in common
stocks. A short-term investment is considered to be an investment with a
maturity of one year or less from the date of issuance. Short-term investments
will not normally represent more than 10% of the Fund's total assets.

      It is the policy of the Fund not to engage in trading for short-term
profits. Nevertheless, changes in the portfolio will be made promptly when
determined to be advisable by reason of developments not foreseen at the time of
the initial investment decision, and usually without reference to the length of
time a security has been held. Accordingly, portfolio turnover rate is not
considered a limiting factor in the execution of investment decisions. The
Fund's portfolio often includes a number of securities which are owned by other
equity mutual funds managed by PMC. See "Investment Policies and Restrictions"
in the Statement of Additional Information for more information.

      Portfolio turnover is not expected to exceed 150% in the coming year. A
high rate of portfolio turnover (100% or more) involves correspondingly greater
transaction costs which must be borne by the Fund and its shareholders. Under
certain circumstances, a high turnover rate may make it more difficult for the
Fund to qualify as a regulated investment company under the Internal Revenue
Code of 1986, as amended (the "Code"). See "Dividends, Distributions and
Taxation."

      The Fund may enter into repurchase agreements, not to exceed seven days,
with broker-dealers and any member bank of the Federal Reserve System. The Board
of Trustees of the Fund will review and monitor the creditworthiness of any
institution which enters into a repurchase agreement with the Fund. Such
repurchase agreements will be fully collateralized with United States ("U.S.")
Treasury and/or agency obligations with a market value of not less than 100% of
the obligations, valued daily. Collateral will be held by the Fund's custodian
in a segregated, safekeeping account for the benefit of the Fund. Repurchase
agreements afford the Fund an opportunity to earn income on temporarily
available cash at low risk. In the event that a repurchase agreement is not
fulfilled, the Fund could suffer a loss to the extent that the value of the
collateral falls below the repurchase price.

      The Fund may lend portfolio securities to member firms of the New York
Stock Exchange (the "Exchange"). 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 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. These investment strategies are also described in the Statement of
Additional Information.

      In pursuit of its objective, the Fund may employ certain active investment
management techniques including options contracts on securities and securities
indices, futures contracts on securities indices and options on such futures
contracts. These techniques may be employed in an attempt to hedge risks
associated with the Fund's portfolio securities. See the Appendix to this
Prospectus and the Statement of Additional Information for a description of
these investment practices and associated risks. The Fund may invest in
restricted and illiquid securities as described in the Statement of Additional
Information.


                                        4
<PAGE>

      The Fund's fundamental investment objective and the fundamental investment
restrictions set forth in the Statement of Additional Information may not be
changed without shareholder approval. Certain other investment policies,
strategies and restrictions on investment are noted throughout the Prospectus
and are set forth in the Statement of Additional Information. These
non-fundamental investment policies, strategies and restrictions may be changed
at any time by a vote of the Board of Trustees.


   
IV. MANAGEMENT OF THE FUND
      The Board of Trustees of the Fund has overall responsibility for
management and supervision of the Fund. There are currently nine Trustees, seven
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 business and professional
background of each Trustee and executive officer of the Fund.
    

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

      Mr. David Tripple, President and Chief Investment Officer of PMC and
Executive Vice President of each Pioneer mutual fund, has general responsibility
for PMC's investment operations and chairs a committee of PMC's domestic equity
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 special equities and smaller
companies. Members of the team meet regularly to discuss holdings, prospective
investments and portfolio composition.

   
      Day-to-day management of the Fund has been the responsibility of Mr.
William Taussig, Vice President of PMC and the Fund, since the Fund's inception.
Mr. Taussig joined PMC in 1991 and has 13 years of investment experience.
    

      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 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 the SEC; (g) all expenses of shareholders' and
Trustees' meetings and of preparing, printing and distributing prospectuses,
notices, proxy statements and all reports to shareholders and to governmental
agencies; (h) charges and expenses of legal counsel to the Fund and the
Trustees; (i) distribution fees paid by the Fund 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 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 1.10% per annum of the
Fund's average daily net assets. The fee is normally computed daily and paid
monthly. See "Expense Information" in the Prospectus and "Investment Adviser" in
the Statement of Additional Information.

V. FUND SHARE ALTERNATIVES
      The Fund offers two Classes of shares designated as Class A and Class B
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 in Class A shares, you will pay an initial
sales charge. Certain purchases may qualify for reduced initial sales charges.
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 contingent deferred sales charge ("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,
eight years after the initial purchase.

      Purchasing Class A or Class B 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. Consult your financial representative for more
information.

      Investment dealers or their representatives may receive different
compensation depending on which Class of shares they sell. Shares sold outside
the U.S. to persons who are not U.S. citizens may be subject to different sales
charges, CDSCs and dealer compensation arrangements in accordance with local
laws and business practices.

VI. SHARE PRICE
      Shares of the Fund are sold at the public offering price, which is the net
asset value per share plus any applicable sales charge. Net asset value per
share of a 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
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. All assets of the
Fund for which there is no other readily available valuation method are valued
at their fair value as determined in good faith by the Trustees.

VII. HOW TO BUY FUND SHARES

      You may buy Fund shares, unless the purchase of Fund shares has been
restricted by management as described below in "Special Restrictions," from any
securities broker- dealer which has a selling 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 $5,000, except as specified below. The
minimum initial investment is $2,000 for IRA accounts. The minimum subsequent
investment is $1,000.

Special Restrictions
   
      Prospective investors should be aware that management intends to close the
Fund to new investments at the end of the fifteenth calendar day after the Fund
reaches $150 million in total assets. No new investments will be accepted in the
ninety-day period immediately after such closure. Subsequent to the end of this
ninety-day period, and depending upon market conditions and the availability of
suitable investments for the Fund, additional investments may be accepted from
existing shareholders. The time period for any such subsequent investments will
be determined by management based primarily on its ability to effectively invest
the Fund's available cash. There is no limitation on purchases of Fund shares
through the reinvestment of dividends and capital gains distributions paid by
the Fund.
    

      As a result of the Fund's intention to close the Fund to new investments,
the Fund is not appropriate for investors who make periodic investments such as
401(k) and 403(b) plans. Certain IRA accounts will be accepted. See "Retirement
Plans."

   
      You may not buy Fund shares by exchanging shares from any other Pioneer
mutual funds that you currently own. You may not buy Fund shares by exercising
the Reinstatement Privilege available on certain other Pioneer mutual funds.
    

     Management reserves the right to modify or eliminate restrictions on the
sale of Fund shares if such action is in the interest of Fund shareholders.

      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 Pioneer mutual fund account, assuming the purchase of shares is not
restricted; 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")
accounts but may not be available to other types of retirement plan accounts.
Call PSC for more information.


                                        6
<PAGE>

      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 receipt of a telephone
purchase instruction and receipt of good funds (usually three days after the
purchase instruction). 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
charge, as follows.

$1 million or more                    -0-           -0-           see below
</TABLE>
    

      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 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 Class A share
investments of $1 million or more subject to a CDSC of 1% which may be imposed
in the event of a redemption of such 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. 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
pays 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 net asset value per share without a sales charge to: (a) current or
former Trustees and officers of the Fund and partners and employees of its legal
counsel; (b) current or former directors, officers, employees or sales
representatives of PGI or its 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 selling agreements with PFD; (e) members
of the immediate families of any of the persons above; (f) any trust, custodian,
pension, profit-sharing or other benefit plan of the foregoing persons; (g)
insurance company separate accounts; (h) certain "wrap accounts" for the benefit
of clients of financial planners adhering to standards established by PFD; (i)
other funds and accounts for which PMC or any of its affiliates serves as
investment adviser or manager; and (j) certain unit investment trusts. Shares so
purchased are purchased for investment purposes and may not be resold except
through redemption or repurchase by or on behalf of the Fund. The availability
of this privilege is conditioned upon the receipt by PFD of written notification
of eligibility. Class A shares of the Fund may also be sold at net asset value
without a sales charge in connection with certain reorganization, liquidation or
acquisition transactions involving other investment companies or personal
holding companies.

   
      Reduced sales charges are available for purchases of $50,000 or more of
Class A shares (excluding any reinvestments of dividends and capital gains
distributions) made within a 13-month period pursuant to a Letter of 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.
    

                                        7
<PAGE>

   
      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.
    

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; 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:


<TABLE>
<CAPTION>
                           CDSC as a Percentage
Year Since                  of Dollar Amount
Purchase                    Subject to CDSC
- ------------------------   --------------------
<S>                               <C>
First                             4.0%
Second                            4.0%
Third                             3.0%
Fourth                            3.0%
Fifth                             2.0%
Sixth                             1.0%
Seventh and thereafter            None
</TABLE>

      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 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"), for which the Fund is applying, 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 be available. The conversion of Class
B shares to Class A shares will not occur if such ruling is not available and,
therefore, Class B shares would continue to be subject to higher expenses than
Class A shares for an indeterminate period.

      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 IRAs 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; (b) the distribution is part of a series of substantially equal
payments made over the life expectancy of the shareholder or the joint life
expectancy of the shareholder and his or her beneficiary or as scheduled
periodic payments to a shareholder (limited in any year to 10% of the value of
the account at the time the distribution amount is established; a required
minimum distribution due to the shareholder's attainment of age 70-1/2 may 
exceed the 10% limit only if the distribution amount is based on assets held by
Pioneer); (c) the distribution is a return of excess employee contributions; (d)
the distribution 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 any applicable CDSC
upon redemption.

      The CDSC on any shares subject to a CDSC may be waived or reduced if 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 either 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 by PFD prior to PFD's close of business (usually, 5:30 p.m.
Eastern Time). It is the responsibility of broker-dealers to transmit orders so
that they will be received by PFD prior to its close of business. PFD or its
affiliates may provide additional compensation to certain dealers or such
dealers' affiliates based on certain objective criteria


                                        8
<PAGE>

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 accepted. The Fund reserves the right to withhold payment of the sale
proceeds until checks received by the Fund in payment for the shares being sold
have cleared, which may take up to 15 calendar days from the purchase date.

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

   
  [bullet]  you wish to sell over $100,000 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 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, and 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 $100,000 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 the bank address of record which must
have been properly predesignated either on your Account Application or on an
Account Options Form and which must not have changed in the last 30 days. To
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
which were not subject to an initial sales charge, may be subject to a CDSC upon
redemption. A CDSC
    


                                        9
<PAGE>

   
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.
    

      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
      At this time, you may not open a new account in the Fund or purchase
shares of the Fund by exchanging shares from any other Pioneer mutual fund that
you already own. You may, however, exchange shares of the Fund for shares of
other Pioneer mutual funds. Such shares may not be exchanged back to this Fund.
Exchanges must be at least $1,000.

      Written Exchanges. You may exchange your Fund shares by sending a letter
of instruction to PSC. Your letter should include your name, the Fund's name 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 by
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 the Fund
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. You may exchange your shares of the Fund 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; the applicable CDSC will carry over to the shares purchased
by exchange.

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

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

X. DISTRIBUTION PLANS
      The Fund, has adopted a Plan of Distribution for both Class A shares
("Class A Plan") and Class B shares ("Class B Plan") in accordance with Rule
12b-1 under the 1940 Act pursuant to which certain distribution and service fees
are paid. Expenditures of the Fund for continuing service fees to broker-dealers
pursuant to the Class A Plan will be accrued daily beginning July 1, 1997; other
expenses pursuant to the Class A Plan will be paid as accrued.

      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


                                       10
<PAGE>

annum of the Fund's daily net assets attributable to Class A shares; (ii)
reimbursement to PFD for its expenditures for broker-dealer commissions and
employee compensation on certain sales of the Fund's Class A shares with no
initial sales charge (See "How to Buy Fund Shares"); and (iii) reimbursement to
PFD for expenses incurred in providing services to Class A shareholders and
supporting broker-dealers and other organizations (such as banks and trust
companies) in their efforts to provide such services. Banks are currently
prohibited under the Glass-Steagall Act from providing certain underwriting or
distribution services. If a bank was prohibited from acting in any capacity or
providing any of the described services, management would consider what action,
if any, would be appropriate.

      Expenditures of the Fund pursuant to the Class A Plan are accrued daily
and may not exceed 0.25% of the Fund's average daily net assets attributable to
Class A shares. Distribution expenses of PFD are expected to substantially
exceed the distribution fees paid by the Fund in a given year. The Class A Plan
does not provide for the carryover of reimbursable expenses beyond 12 months
from the time the Fund is first invoiced for an expense. In the event of
termination or non-continuance of the Class A Plan, the Fund has 12 months to
reimburse any expense which it incurs prior to such event, provided that
payments by the Fund during such 12-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.

      The Class B Plan provides that the Fund compensates PFD through the
payment of a distribution fee at the annual rate of 0.75% of the Fund's average
daily net assets attributable to Class B shares and a service fee at the annual
rate of 0.25% of the Fund's average daily net assets attributable to Class B
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 shares. PFD also receives the proceeds of any CDSC imposed on the redemption
of Class B 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.

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

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

      The Fund's policy is to pay to shareholders dividends from net investment
income, if any, and to make distributions from net long-term capital gains, if
any, usually in December. Distributions from net short-term capital gains, if
any, may be paid with such dividends; dividends from income and/or capital gains
may also be paid at such times as may be necessary for the Fund to avoid federal
income or excise tax. Generally, dividends from the Fund's net investment
income, market discount income, net short-term capital gains, and certain net
foreign exchange gains are taxable under the Code as ordinary income, and
dividends from the Fund's net long-term capital gains are taxable as long-term
capital gains.

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

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

      Dividends and other distributions and the proceeds of redemptions,
exchanges or repurchases of Fund shares paid to individuals and other non-exempt
payees will be subject to a 31% backup withholding of federal income tax if the
Fund is not provided with the shareholder's correct taxpayer identification
number and certification that the number is correct and that the shareholder is
not subject to 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,


                                       11
<PAGE>

i.e., U.S. citizens or residents or U.S. corporations, partnerships, trusts or
estates and who are subject to U.S. federal income tax. Non-U.S. shareholders
and tax-exempt shareholders are subject to a tax treatment different than that
described above. Shareholders should consult their own tax advisers regarding
state, local and other applicable tax laws.

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

Account and Confirmation Statements
      PSC maintains an account for each shareholder and all transactions of the
shareholder are recorded in this account. Confirmation statements showing
details of transactions are sent to shareholders as transactions occur. The
Pioneer Combined Account Statement, mailed quarterly, is available to
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 which might not be available are purchases,
exchanges or redemptions of shares by mail or telephone, automatic reinvestment
of dividends and capital gains distributions, withdrawal plans, and newsletters.

Additional Investments
      You may add to your account, unless the Fund is closed to new investments,
by sending a check (minimum of $1,000) 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 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.

Financial Reports and Tax Information
      As a shareholder, you will receive financial reports at least
semiannually. In January of each year, the Fund will mail 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 your
distribution options may be made by written request to PSC.

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

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, PSC will record each telephone transaction, require the caller to
provide the personal identification number ("PIN") for the account and send you
a written confirmation of each telephone transaction. Different procedures may
apply to accounts that are registered to non-U.S. citizens or that are held in
the name of an institution or in the name of an investment broker-dealer or
other third-party. If reasonable procedures, such as those described above, are
not followed, the Fund may be liable for any loss due to unauthorized or
fraudulent instructions. The Fund may implement other procedures from time to
time. In all other cases, neither the 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.


                                       12
<PAGE>

      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 mutual fund 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 Sell Fund Shares," "How to
Exchange Fund Shares" and "Telephone Transactions and Related Liabilities." Call
PSC for assistance.

Retirement Plans
      Rollover and contributory IRA accounts may invest in the Fund. The minimum
initial investment for IRA accounts is $2,000. Retirement plans that must make
periodic investments may not invest in the Fund because periodic investments
will not be allowed after management closes the Fund to new investments (see
"How to Buy Fund Shares--Special Restrictions"). The Account Application
accompanying this Prospectus should not be used to establish an IRA account. A
separate application is required.

      Contact the Retirement Plans Department of PSC at 1-800-622-0176 for
information relating to retirement plans for businesses, age-weighted profit
sharing plans, Simplified Employee Pension Plans, IRAs, and Section 403(b)
retirement plans for employees of certain non-profit organizations and public
school systems, all of which are available in conjunction with investments in
most other Pioneer mutual funds.

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
Systematic Withdrawal Plan ("SWP") providing for fixed payments at regular
intervals. Withdrawals from Class B share accounts are limited to 10% of the
value of the account at the time the SWP is implemented. See "Waiver or
Reduction of Contingent Deferred Sales Charge" for more information. Periodic
payments of $50 or more will be sent to you, or any person designated by you,
monthly or quarterly, and your periodic redemptions of shares may be taxable to
you. Payments can be made either by check or electronic transfer to a bank
account designated by you. If you direct that withdrawal checks be paid to
another person after you have opened your account, a signature guarantee must
accompany your instructions. Purchases of Class A shares of the Fund at a time
when you have a SWP in effect may result in the payment of unnecessary sales
charges and may therefore be disadvantageous. You may obtain additional
information by calling PSC at 1-800-225-6292 or by referring to the Statement of
Additional Information.

      The options and services available to shareholders, including the terms of
the Exchange Privilege, 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 request by
calling 1-800-225-6292.

XIII. THE FUND
      The Fund is a diversified open-end management investment company (commonly
referred to as a mutual fund) organized as a Delaware business trust on December
3, 1996. The Fund has authorized an unlimited number of shares of beneficial
interest. As an open-end management investment company, the Fund continuously
offers its shares, subject to the restrictions described above, to the public
and under normal conditions must redeem its shares upon the demand of any
shareholder at the then current net asset value per share. See "How to Sell Fund
Shares." The Fund is not required, and does not intend, to hold annual
shareholder meetings although special meetings may be called for the purpose of
electing or removing Trustees, changing fundamental investment restrictions or
approving a management contract.

      The Fund reserves the right to create and issue additional series of
shares. The Trustees have the authority, without further shareholder approval,
to classify and reclassify the shares of the Fund, or any additional series of
the Fund, into one or more classes. As of the date of this Prospectus, the
Trustees have authorized the issuance of two classes of shares, designated Class
A and Class B. 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 and Class B shareholders have
exclusive voting rights with respect to the Rule 12b-1 distribution plans
adopted by holders of those shares in connection with the distribution of
shares.

      In addition to the requirements under Delaware law, the Declaration of
Trust provides that a shareholder of the Fund may bring a derivative action on
behalf of the Fund only if the following conditions are met: (a) shareholders
eligible to bring such derivative action under Delaware law who hold at least
10% of the outstanding shares of the Fund, or 10% of the out-


                                       13
<PAGE>

standing shares of the series or class to which such action relates, shall join
in the request for the Trustees to commence such action; and (b) the Trustees
must be afforded a reasonable amount of time to consider such shareholder
request and investigate the basis of such claim. The Trustees shall be entitled
to retain counsel or other advisers in considering the merits of the request and
shall require an undertaking by the shareholders making such request to
reimburse the Fund for the expense of any such advisers in the event that the
Trustees determine not to bring such action.

      When issued and paid for in accordance with the terms of the Prospectus
and Statement of Additional Information, shares of the Fund are fully-paid and
non-assessable. Shares will remain on deposit with the Fund's transfer agent and
certificates will not normally be issued. The Fund reserves the right to charge
a fee for the issuance of Class A share certificates; certificates will not be
issued for Class B shares. In order to supply the Fund with capital, PFD
beneficially owned 100% of the Fund's issued and outstanding shares immediately
prior to effectiveness of the Fund's registration statement. The Fund expects to
have significant assets in comparison to PFD's initial investment soon after
effectiveness and therefore PFD may no longer control the Fund.

XIV. INVESTMENT RESULTS
      The average annual total return (for a designated period of time) on an
investment in the Fund may be included in advertisements, and furnished to
existing or prospective shareholders. The average annual total return for each
Class is computed in accordance with the SEC's standardized formula. The
calculation for all Classes assumes the reinvestment of all dividends and
distributions at net asset value and does not reflect the impact of federal or
state income taxes. In addition, for Class A shares the calculation assumes the
deduction of the maximum sales charge of 5.75%; for Class B 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 results of the Fund. Rankings or listings by
magazines, newspapers or independent statistical or rating services, such as
Lipper Analytical Services, Inc., may also be referenced.

      The Fund'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.

APPENDIX--CERTAIN INVESTMENT PRACTICES
      This Appendix provides a brief description of certain investment
techniques that the Fund may employ. For a more complete discussion of these and
other practices, see "Investment Policies and Restrictions" in the Statement of
Additional Information.

Real Estate Investment Trusts and Associated Risk Factors
      REITs are pooled investment vehicles which invest primarily in income
producing real estate or real estate related loans or interests. REITs are
generally classified as equity REITs, mortgage REITs or a combination of equity
and mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments.

      Investing in REITs involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. Equity
REITs may be affected by changes in the value of the underlying property owned
by the REITs, while mortgage REITs may be affected by the quality of any credit
extended. REITs are dependent upon management skills, are not diversified, and
are subject to the risks of financing projects. REITs are subject to heavy cash
flow dependency, default by borrowers, self-liquidation, and the possibilities
of failing to qualify for the exemption from tax for distributed income under
the Code and failing to maintain their exemptions from the Investment Company
Act of 1940, as amended.

      REITs (especially mortgage REITs) are also subject to interest rate risks.
When interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline.

      Investing in REITs involves risks similar to those associated with
investing in small capitalization companies. Historically, REITs, like small
capitalization stocks, have been more volatile in price than the larger
capitalization stocks included in the Standard & Poor's Index of 500 Common
Stocks.

Options on Securities and Securities Indices
      The Fund may purchase put and call options on securities in which the Fund
may invest and securities indices that are based on securities in which it may
invest to manage cash flow and to manage its exposure to stocks or stock markets
instead of, or in addition to, buying and selling stock. The Fund may also
purchase options in order to hedge against risks of market-wide price
fluctuations.

      The Fund may purchase put options in order to hedge against an anticipated
decline in securities prices that might adversely affect the value of the Fund's
portfolio securities. If


                                       14
<PAGE>

the Fund purchases a put option on a security or securities index, the amount of
the payment it would receive upon exercising the option would depend on the
extent of any decline in the value of the security or the securities index below
the exercise price. Such payments would tend to offset a decline in the value of
the Fund's portfolio securities. However, if the value of the security or
securities index increases and remains above the exercise price while the put
option is outstanding, the Fund will not be able to profitably exercise the
option and will lose the amount of the premium and any transaction costs. Such
loss may be partially offset by an increase in the value of the Fund's portfolio
securities.

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

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

Futures Contracts and Options on Futures Contracts
      To hedge against changes in securities prices, the Fund may purchase and
sell various kinds of futures contracts, and purchase and write call and put
options on any of such futures contracts. When the Fund enters into a futures
contract, it agrees to purchase or sell the underlying security at a given price
on a specified future date. When the Fund enters into an option on a futures
contract, it has the right--but not the obligation--to purchase or sell the
related futures contract at a given price on a specified future date. The Fund
may also enter into closing purchase and sale transactions with respect to any
of such contracts and options. The futures contracts may be based on various
securities indices. The Fund will engage in futures and related options
transactions for hedging purposes only. These transactions involve brokerage
costs and require margin deposits.

Limitations and Risks Associated with Transactions in Options and Futures
Contracts

      Transactions involving options on securities and securities indices,
futures contracts and options on futures involve: (1) liquidity risk that
contractual positions cannot be easily closed out in the event of market changes
or generally in the absence of a liquid secondary market, (2) correlation risk
that changes in the value of hedging positions may not match the securities
market intended to be hedged and (3) market risk that an incorrect prediction of
securities prices by the Fund's investment adviser may cause the Fund to perform
less favorably than if such positions had not been entered. The Fund will
purchase and sell options that are traded only in a regulated market which is
open to the public. Options and futures contracts are highly specialized
activities which involve investment techniques and risks that are different from
those associated with ordinary portfolio transactions. The Fund may not enter
into futures contracts and options on futures contracts for speculative
purposes. All of the Fund's assets may be subject to futures contracts and
options on such contracts entered into for bona fide hedging purposes. The loss
that may be incurred by the Fund in entering into future contracts and written
options thereon is potentially unlimited. The Fund may not invest more than 5%
of its total assets in financial instruments that are used for non-hedging
purposes.

      The Fund's transactions in options, futures contracts and options on
futures contracts may be limited by the requirements for qualification of the
Fund as a regulated investment company for tax purposes. See "Tax Status" in the
Statement of Additional Information.

1. INVESTMENT POLICIES AND RESTRICTIONS

   
The  Fund's  current  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.  This  Statement  of  Additional  Information  should  be read be read in
conjunction with the Prospectus.  Capitalized terms not otherwise defined herein
have the meaning given to them in the Prospectus.
    

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

Lending of Portfolio Securities

The Fund may lend  portfolio  securities  to member  firms of the New York Stock
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  as well  as the  benefit  of an  increase  in the  market  value  of 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 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 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.

Risk Factors Associated with the Real Estate Industry

Although the Fund does not invest directly in real estate, it may invest in real
estate  equity  securities.  To the extent that the Fund  invests in real estate
equity  securities,  an  investment  in the Fund may be subject to certain risks
generally  associated with the direct ownership of real estate and with the real
estate industry in general. These risks include, among others: possible declines
in the value of real  estate;  risks  related  to  general  and  local  economic
conditions;  possible  lack of  availability  of mortgage  funds;  overbuilding;
extended vacancies of properties;  increases in competition,  property taxes and
operating  expenses;  changes in zoning laws;  costs resulting from the clean-up
of, and liability to third  parties for damages  resulting  from,  environmental
problems;  casualty or  condemnation  losses;  uninsured  damages  from  floods,
earthquakes or other natural disasters;  limitations on and variations in rents;
and  changes  in  interest  rates.  Investments  by the  Fund in  securities  of
companies  providing  mortgage  servicing may be subject to the risks associated
with refinancings and their impact on servicing rights.

Real Estate Investment Trusts and Associated Risk Factors

                                       2
<PAGE>

   
The Fund may invest in shares of Real  Estate  Investment  Trusts  ("REITs")  as
described in the Prospectus.  REITs are pooled investment  vehicles which invest
primarily  in income  producing  real  estate or real  estate  related  loans or
interests.  REITs are generally classified as equity REITs,  mortgage REITs or a
combination  of equity and mortgage  REITs.  Equity REITs invest the majority of
their assets  directly in real  property and derive  income  primarily  from the
collection  of rents.  Equity  REITs can also realize  capital  gains by selling
properties that have appreciated in value. Mortgage REITs invest the majority of
their assets in real estate  mortgages and derive income from the  collection of
interest  payments.  Like investment  companies such as the Fund,  REITs are not
taxed on income  distributed to  shareholders  provided they comply with several
requirements of the Internal Revenue Code of 1986, as amended (the "Code").  The
Fund will indirectly bear its proportionate  share of any expenses paid by REITs
in which it invests in addition to the expenses paid by the Fund.
    

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

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

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

Options on Securities and Securities Indices

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

   
The Fund may only  purchase and sell options that are traded only in a regulated
market  which is open to the  public.  Currently,  options on stock  indices are
traded only on national securities  exchanges or  over-the-counter,  both in the
U.S. and in foreign countries. A securities index fluctuates with changes in the
market values of the securities  included in the index. For example,  some stock
index options are based on a broad market index such as the S&P 500 or the Value
Line  Composite  Index in the U.S.,  the  Nikkei in Japan or the FTSE 100 in the
United Kingdom.  Index options may also be based on a narrower market index such
as the S&P 100 or on an industry or market  segment such as the AMEX Oil and Gas
Index or the Computer and Business Equipment Index.
    

                                       3
<PAGE>

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

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

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

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

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

Futures Contracts and Options on Futures Contracts

To hedge against  changes in securities  prices,  the Fund may purchase and sell
various kinds of futures  contracts,  and purchase and write (sell) call and put
options on any of such futures  contracts.  The Fund may also enter into closing
purchase  and  sale  transactions  with  respect  to any of such  contracts  and
options.  The futures contracts may be based on various  securities in which the
Fund may invest,  securities  indices that  composed of  securities in which the
Fund may invest,  and other  financial  instruments  and indices.  The Fund will
engage in futures and related  options  transactions  for bona fide  hedging and
non-hedging  purposes as described below. All futures  contracts entered into by
the Fund are traded on U.S.  exchanges  or boards of trade that are licensed and
regulated by the Commodity Futures Trading Commission (the "CFTC").

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

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

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting  transactions which may result in a profit
or a loss.  While futures  contracts on securities will usually be liquidated in
this manner,  the Fund may instead  make,  or take,  delivery of the  underlying
securities  whenever it appears  economically  advantageous to do so. A clearing
corporation  associated  with the exchange on which  futures on  securities  are
traded guarantees that, if still open, the sale or purchase will be performed on
the settlement date.

Hedging  Strategies.  Hedging,  by use of futures contracts,  seeks to establish
with more certainty the effective  price of portfolio  securities and securities
that the Fund owns or proposes to acquire.  The Fund may,  for  example,  take a
"short" position in the futures market by selling futures  contracts in order to
hedge  against an  anticipated  decline in market  prices  that would  adversely
affect the value of the Fund's portfolio securities.  Such futures contracts may
include  contracts  for the future  delivery of  securities  held by the Fund or
securities  with  characteristics  similar  to  those  of the  Fund's  portfolio
securities.  If, in the opinion of Pioneering  Management  Corporation  ("PMC"),
there is a sufficient degree of correlation  between price trends for the Fund's
portfolio  securities and futures  contracts  based on securities and securities
indices or other indices, the Fund may also enter into such futures contracts as
part of their hedging  strategies.  Although under some circumstances  prices of
securities  in the Fund's  portfolio may be more or less volatile than prices of
such  futures  contracts,  PMC will  attempt  to  estimate  the  extent  of this
volatility  difference based on historical  patterns and compensate for any such
differential by having the Fund enter into a greater or lesser number of futures
contracts or by attempting to achieve only a partial hedge against price changes
affecting the Fund's  portfolio  securities.  When hedging of this  character is
successful,  any  depreciation  in the  value of  portfolio  securities  will be
substantially  offset by appreciation in the value of the futures  position.  On
the other  hand,  any  unanticipated  appreciation  in the  value of the  Fund's
portfolio  securities would be substantially offset by a decline in the value of
the futures position.

                                       5
<PAGE>

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

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

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

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

The  Fund  may use  options  on  futures  contracts  for bona  fide  hedging  or
non-hedging purposes as discussed below.

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  only for bona fide hedging or  non-hedging  purposes in accordance
with  CFTC  regulations  which  permit  principals  of  an  investment   company
registered under the 1940 Act to engage in such transactions without registering
as commodity pool operators.  The Fund is not permitted to engage in speculative
futures  trading.  The Fund will  determine that the price  fluctuations  in the
futures  contracts  and  options  on  futures  used  for  hedging  purposes  are
substantially  related to price  fluctuations  in securities held by the Fund or
which the Fund expects to purchase.  Except as stated below,  the Fund's futures
transactions  will be entered  into for  traditional  hedging  purposes -- i.e.,
futures  contracts  will be sold to  protect  against a decline  in the price of
securities that the Fund owns, or futures contracts will be purchased to protect
the Fund against an increase in the price of  securities it intends to purchase.
As evidence of this hedging intent,  the Fund expects that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of purchasing, equivalent amounts of related securities at the time when
the futures or option position is closed out. However, in particular cases, when
it is economically  advantageous  for the Fund to do so, a long futures position
may be terminated or an option may expire without the corresponding  purchase of
securities or other assets.

As an alternative to literal compliance with the bona fide hedging definition, a
CFTC regulation permits the Fund to elect to comply with a different test, under
which the sum of the amounts of initial margin  deposits on the Fund's  existing
non-hedging  futures  contracts and premiums paid for options on futures entered
into for  non-hedging  purposes  (net of the  amount the  positions  are "in the
money") would not exceed 5% of the market value of the Fund's total assets.  The
Fund will engage in transactions  in futures  contracts and related options only
to the extent such  transactions  are consistent  with the  requirements  of the
Code, for maintaining its  qualifications as a regulated  investment company for
federal income tax purposes.

                                       6
<PAGE>

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

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

Restricted and Illiquid Securities

With respect to liquidity  determinations  generally,  the Board of Trustees has
the  ultimate   responsibility  for  determining  whether  specific  securities,
including Rule 144A securities,  are liquid or illiquid. The Board has delegated
the function of making day to day  determinations  of liquidity to PMC, pursuant
to  guidelines  reviewed  by the  Trustees.  PMC takes into  account a number of
factors in reaching liquidity  decisions.  These factors may include but are not
limited to: (i) the  frequency  of trading in the  security;  (ii) the number of
dealers who make quotes in the securities;  (iii) the number of dealers who have
undertaken  to make a market  in the  security;  (iv) the  number  of  potential
purchasers;  and (v) the nature of the  security  and how  trading  is  effected
(e.g.,  the time needed to sell the  security,  how offers are solicited and the
mechanics of  transfer).  PMC will monitor the  liquidity of  securities  in the
Fund's portfolio and report periodically on such decisions to the Trustees.

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

Although there is not requirement to do so, the Fund currently  intends to limit
its investments in illiquid securities, including certain restricted securities,
to 5% of total  assets and to limit its  investments  in  restricted  securities
determined not to be illiquid to 5% of total assets.

Investment Restrictions

Fundamental  Investment  Restrictions.  The Fund has adopted certain  additional
investment restrictions which may not be changed without the affirmative vote of
the  holders  of a  "majority"  (as  defined  in the  1940  Act)  of the  Fund's
outstanding voting securities. The Fund may not:

   
         (1)......Issue  senior  securities,  except as  permitted by the Fund's
borrowing,  lending  and  commodity  restrictions  and,  for  purposes  of  this
restriction,  the issuance of shares of beneficial  interest in multiple classes
or series,  the purchase or sale of options,  futures  contracts  and options on
futures  contracts,  forward  commitments,  forward foreign exchange  contracts,
repurchase  agreements,  fully covered  reverse  repurchase  agreements,  dollar
rolls,  swaps and any other financial  transaction  entered into pursuant to the
Fund's investment  policies as described in the Prospectus and this Statement of
Additional Information and in accordance with applicable Securities and Exchange
Commission (the "Commission") pronouncements, as well as the pledge, mortgage or
hypothecation  of the  Fund's  assets  within  the  meaning  of the  fundamental
investment   restriction  regarding  pledging,  are  not  deemed  to  be  senior
securities.
    

                                       7
<PAGE>

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

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

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

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

         (6)......Make  loans,  except by the  purchase of debt  obligations  in
which the Fund may invest consistent with its investment  policies,  by entering
into repurchase  agreements or through the lending of portfolio  securities,  in
each case only to the extent  permitted by the  Prospectus and this Statement of
Additional Information.

         (7)......With respect to 75% of its total assets, purchase securities
of an issuer (other than the U.S. Government, its agencies or 
instrumentalities), if

                  (a) such purchase would cause more than 5% of the Fund's total
         assets, taken at market value, to be invested in the securities of such
         issuer, or

                  (b) such purchase would at the time result in more than 10% of
         the  outstanding  voting  securities  of such issuer  being held by the
         Fund.

   
It is the  fundamental  policy of the Fund not to concentrate its investments in
securities  of  companies  in any  particular  industry.  Following  the current
opinion of the staff of the Commission,  the Fund's investments are concentrated
in a particular industry if such investments aggregate 25% or more of the Fund's
total assets. The Fund's policy does not apply to investments in U.S. government
Securities.
    

The Fund does not  intend to enter into any  reverse  repurchase  agreements  or
dollar rolls, lend portfolio securities or invest in foreign securities, forward
currency contracts, options or futures on foreign currencies or securities index
put and call warrants, as described in fundamental investment  restrictions (1),
(2) and (6) above,  during the coming year. In addition,  in compliance  with an
informal position taken by the staff of the Commission  regarding leverage,  the
Fund  will not  purchase  securities  during  the  coming  year at any time that
outstanding borrowings exceed 5% of the Fund's total assets.

The Fund's  Declaration of Trust (the  "Declaration of Trust") provides that the
holders of two-thirds of its outstanding  shares may vote to remove a Trustee of
the Fund at any meeting of shareholders.  See "Description of Shares" below. The
business  address of all  officers  is 60 State  Street,  Boston,  Massachusetts
02109.
The expense of organizing  the Fund and initially  registering  its shares under
federal and state securities laws are being charged to the Fund's operations, as
an  expense,  over a period not to exceed 60 months  from the  Fund's  inception
date. If any of the original  shares are redeemed by any holder thereof prior to
the end of the amortization period, the redemption proceeds will be decreased by
the pro rata share of the unamortized expenses as of the date of redemption. The
pro rata shares is derived by dividing the number of original shares redeemed by
the total number of original shares outstanding at the time of redemption.

All of the outstanding  capital stock of PFD, PMC and PSC is owned,  directly or
indirectly,  by PGI, a  publicly-owned  Delaware  corporation.  PMC,  the Fund's
investment  adviser,  serves as the  investment  adviser for the Pioneer  mutual
funds  listed  below  and  manages  the  investments  of  certain  institutional
accounts.

         The table below lists all the Pioneer mutual funds currently offered to
the public and the investment adviser and principal underwriter for each fund.

3. INVESTMENT ADVISER

The Fund has contracted with PMC, 60 State Street, Boston, Massachusetts, to act
as its investment  adviser.  A description of the services  provided to the Fund
under  its  management  contract  and the  expenses  paid by the Fund  under the
contract is set forth in the  Prospectus  under the caption  "Management  of the
Fund."

The term of the management contract is one year and is renewable annually by the
vote of a majority of the Board of Trustees of the Fund (including a majority of
the Board of Trustees who are not parties to the contract or interested  persons
of any such  parties).  The vote must be 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 upon sixty  days'  written
notice  by vote of the Board of  Directors  or  Trustees  or a  majority  of the
outstanding voting securities. 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 willful misfeasance, bad faith or gross
negligence  in the  performance  of its  duties  or by  reason  of its  reckless
disregard  of  its  obligations  and  duties  under  the  respective  management
contract.

As  compensation  for its  management  services  and expenses  incurred,  PMC is
entitled to a management  fee from the Fund at the rate of 1.10% per annum of he
Fund's average daily net assets.  The fee is normally computed and accrued daily
and paid monthly.

   
PMC has agreed not to impose  all or a portion of its  management  fees and make
other  arrangements,  if  necessary,  to limit  expenses  for the Fund's Class A
shares to not more than 1.75% of such Class's average net assets. The management
fee  attributable  to the Fund's  Class B shares will not be imposed to the same
extent that it is not imposed for Class A shares.  This  agreement  is temporary
and  voluntary  and  may  be  terminated  at  any  time  by  PMC.  See  "Expense
Information" in the Prospectus.

     The  Fund  paid  no  management  fees  for the  period  February  28,  1997
(commencement  of  operations)  through May 31, 1997. If PMC's fee reduction and
expense  limitation had not been in effect,  the Fund would have paid management
fees of $102,038 for the period.
    

4. UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

The Fund  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  expenses  for the
distribution of the Fund's shares, except for expenses incurred by PFD for which
it is reimbursed by the Fund under the Plan. 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 and the laws of  certain
foreign countries.  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.

                                       13
<PAGE>

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

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 each
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 shares.
    

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.   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 of a portion of the  distribution  fees described  above to be paid to
the broker-dealer.

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  contingent   deferred  sales  charges   ("CDSCs")
attributable to Class B shares. (See "Distributions Plans" in the Prospectus.)

General

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

                                       14
<PAGE>

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

The Plans were adopted by a majority  vote of the Board of  Trustees,  including
all of the Trustees who are not, and were not at the time they voted, interested
persons  of the Fund,  as  defined in the 1940 Act (none of whom had or have any
direct or indirect  financial  interest in the operation of the Plans),  cast in
person at a meeting called for the purpose of voting on the Plans.  In approving
the Plans, the Trustees identified and considered a number of potential benefits
which the Plans may  provide.  The Board of  Trustees  believes  that there is a
reasonable  likelihood  that the Plans will benefit each Fund and their  current
and future shareholders. Under their terms, the Plans remain in effect from year
to year provided such  continuance is approved  annually by vote of the Trustees
in the  manner  described  above.  The  Plans  may not be  amended  to  increase
materially the annual  percentage  limitation of average net assets which may be
spent for the services described therein without approval of the shareholders of
the 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 period February 28, 1997 (commencement of operations) through May 31,
1997, the Fund incurred total  distribution fees of $10,404 and $51,146 pursuant
to the Fund's Class A Plan and Class B Plan, respectively.

Redemptions  of each Class of shares  may be subject to a CDSC.  A CDSC of 1.00%
may be  imposed  on  certain  net  asset  purchases  of Class A shares  that are
redeemed  within one year of purchase.  Class B shares that are redeemed  within
six years of purchase are subject to a CDSC at declining rates beginning at 4.0%
based on the lower of cost or market value of shares being  redeemed.  See " How
to Buy Fund  Shares" in the  Prospectus.  During the period  February  28,  1997
(commencement  of  operations)  through  May 31,  1997,  CDSCs in the  amount of
approximately  $2,269  were  paid  to  PFD.  Such  CDSCs  are  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, to act
as  shareholder  servicing  and  transfer  agent  for the  Fund.  This  contract
terminates  if assigned and may be  terminated  without  penalty by either party
upon ninety days'  written  notice by vote of its Board of Directors or Trustees
or a majority of its outstanding voting securities.

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 shareholder inquiries.

                                       15
<PAGE>

PSC  receives  an annual fee of $22.75 for each Class A and Class B  shareholder
account from the Fund as compensation  for the services  described above. PSC is
also reimbursed by the Fund for its cash out-of-pocket expenditures.  The annual
fee is set at an  amount  determined  by  vote  of a  majority  of the  Trustees
(including a majority of the  Trustees who are not parties to the contract  with
PSC or interested persons of any such parties) to be comparable to fees for such
services  being  paid by other  investment  companies.  The Fund may  compensate
entities which have agreed to provide certain sub-accounting  services,  such as
specific transaction processing or 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.

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 a 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 serves as the  principal  underwriter  for the Fund in  connection  with the
continuous  offering  of the Class A and Class B shares of the Fund.  During the
period February 28, 1997 (commencement of operations)  through May 31, 1997, net
underwriting  commissions retained by PFD in connection with its offering of the
Class A shares of the Fund were approximately $23,000.  Commissions reallowed to
dealers by PFD in such period were approximately  $1,019,000.  See "Underwriting
Agreement and  Distribution  Plans" 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 or a merger or other reorganization.

8. INDEPENDENT PUBLIC ACCOUNTANTS

   
Arthur Andersen LLP, 225 Franklin Street,  Boston,  Massachusetts  02110, is the
Fund's  independent  public  accountants,  providing audit services,  tax return
review,  and  assistance  and  consultation  with respect to the  preparation of
filings with the Commission.
    

9. PORTFOLIO TRANSACTIONS

All orders for the purchase or sale of portfolio securities are placed on behalf
of the Fund by PMC  pursuant to  authority  contained  in the Fund's  management
contract.  In selecting  brokers or dealers,  PMC will consider various relevant
factors,  including,  but not limited to, the size and type of the  transaction;
the nature and  character  of the markets for the  security to be  purchased  or
sold; the execution efficiency,  settlement capability,  and financial condition
of the dealer;  the dealer's  execution services rendered on a continuing basis;
and the reasonableness of any dealer spreads.

PMC may select  broker-dealers  which provide brokerage and/or research services
to the Fund and/or other investment  companies  managed by PMC. In addition,  if
PMC  determines  in good  faith  that the  amount of  commissions  charged  by a
broker-dealer  is  reasonable  in  relation  to the value of the  brokerage  and
research services provided by such broker,  the Fund may pay commissions to such
broker-dealer in an amount greater than the amount another firm may charge. Such
services may include advice concerning the value of securities; the advisability
of  investing  in,  purchasing  or  selling  securities;   the  availability  of
securities or the purchasers or sellers of securities;  furnishing  analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio  strategy  and  performance  of  accounts;  and  effecting  securities
transactions and performing  functions incidental thereto (such as clearance and
settlement). PMC maintains a listing of 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 dealers  solely  because such services were
provided.

The  research  received  from  broker-dealers  may be useful to PMC in rendering
investment management services to the Fund as well as other investment companies
managed  by PMC,  although  not all such  research  may be  useful  to the Fund.
Conversely,  such  information  provided by brokers or dealers who have executed
transaction  orders on behalf of such other 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 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.

                                       17
<PAGE>

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

It is possible that at times identical  securities will be held by more than one
fund  and/or  account.  However,  positions  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 may not be able to
acquire as large a position in such security as it desires, 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  fund or  account,  the
resulting  participation in volume  transactions could produce better executions
for the Fund or the  account.  In the event more than one account  purchases  or
sells the same  security on a given date,  the purchases and sales will normally
be made as  nearly  as  practicable  on a pro rata  basis in  proportion  to the
amounts desired to be purchased or sold by each.

   
         During the period from February 28, 1997 through May 31, 1997, the Fund
paid  or  accrued   aggregate   brokerage  and   underwriting   commissions   of
approximately $58,648.
    

10. TAX STATUS AND DIVIDENDS

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 timing of its distributions.
If the Fund meets all such  requirements  and distributes to its shareholders at
least  annually all investment  company  taxable income and net capital gain, if
any,  which it  receives,  the Fund will be relieved of the  necessity of paying
federal income tax.

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

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

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.

                                       18
<PAGE>

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 in any year to offset net capital gains,  if any,  during the eight
years following the year of the loss. To the extent subsequent net capital gains
are offset by such losses, they would not result in federal income tax liability
to such Fund and are not expected to be distributed as such to shareholders.

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

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

In addition,  if 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,  the sales
charge paid on such shares is not included in their tax basis under the Code and
(2) in the case of an  exchange,  all or a portion of the sales  charge  paid on
such shares is not  included in their tax basis under the Code,  to the extent a
sales  charge  that  would  otherwise  apply to the shares  received  is reduced
pursuant to the exchange  privilege.  In either  case,  the portion of the sales
charge not included in the tax basis of the shares redeemed or surrendered in an
exchange is included in the tax basis of the shares acquired in the reinvestment
or exchange.  Losses on certain  redemptions may be disallowed under "wash sale"
rules in the event of other  investments  in the same Fund within a period of 61
days  beginning  30 days before and ending 30 days after a  redemption  or other
sale of  shares.  In such a case,  the  disallowed  portion of any loss would be
included  in  the  federal  tax  basis  of the  shares  acquired  in  the  other
investments.

Options written or purchased and futures  contracts  entered into by the Fund on
certain  securities and securities and securities  indices may cause the Fund to
recognize gains or losses from  marking-to-market at the end of its taxable year
even though such options may not have  lapsed,  been closed out, or exercised or
such futures or forward contracts may not have been performed or closed out. The
tax rules  applicable  to these  contracts  may affect the  characterization  as
long-term or short-term  of some capital gains and losses  realized by the Fund.
Losses on  certain  options,  futures  and/or  offsetting  positions  (portfolio
securities or other  positions  with respect to which the Fund's risk of loss is
substantially  diminished by one or more options,  futures or forward contracts)
may also be deferred  under the tax straddle  rules of the Code,  which may also
affect the  characterization  of capital gains or losses from straddle positions
and  certain  successor  positions  as  long-term  or  short-term.  Certain  tax
elections may be available that would enable the Fund to ameliorate some adverse
effects of the tax rules described in this paragraph.  The tax rules  applicable
to options,  futures, and straddles may affect the amount,  timing and character
of the Fund's income and loss and hence of its distributions to shareholders.

                                       19
<PAGE>

For purposes of the 70%  dividends-received  deduction available to corporations
under the Code,  dividends received by the Fund from U.S. domestic  corporations
in respect of any share of stock with a tax  holding  period of at least 46 days
(91 days in the case of certain preferred stock) held in an unleveraged position
and  distributed  and  designated  by the  Fund  may be  treated  as  qualifying
dividends.  Any corporate  shareholder  should consult its tax adviser regarding
the  possibility  that its tax basis in its shares may be  reduced,  for federal
income  tax  purposes,  by reason of  "extraordinary  dividends"  received  with
respect  to the  shares.  In  order  to  qualify  for the  deduction,  corporate
shareholders must meet the minimum holding period  requirement stated above with
respect to their Fund shares,  taking into account any holding period reductions
from certain  hedging or other  transactions  that diminish  risk of loss,  with
respect to their Fund shares and, if they borrow to acquire Fund shares,  may be
denied a portion of the  dividends-received  deduction.  The  entire  qualifying
dividend,  including  the  otherwise  deductible  amount,  will be  included  in
determining the excess (if any) of a  corporation's  adjusted  current  earnings
over its alternative minimum taxable income,  which may increase a corporation's
alternative minimum tax liability.

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

Federal law requires  that the Fund  withhold (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 W-9 Forms,  that their Social Security or
other Taxpayer  Identification Number is correct and that they are not currently
subject to backup withholding,  or that they are exempt from backup withholding.
The Fund may nevertheless be required to withhold if it receives notice from the
IRS or a broker that the number  provided is incorrect or backup  withholding is
applicable  as a result of  previous  underreporting  of  interest  or  dividend
income.

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

The  description of certain  federal tax  provisions  above relates only to U.S.
federal income tax consequences for  shareholders  who are U.S.  persons,  i.e.,
U.S. citizens or residents and U.S. domestic corporations,  partnerships, trusts
or estates, and who are subject to U.S. federal income tax. The description does
not address the special tax rules  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% U.S. withholding tax (or withholding tax at a lower treaty rate) on
amounts treated as ordinary dividends from the Fund and, unless an effective IRS
Form W-8 or  authorized  substitute  is on file,  to 31% backup  withholding  on
certain other payments from the Fund.  Shareholders should consult their own tax
advisers on these matters and on state, local and other applicable tax laws.

11. DESCRIPTION OF SHARES

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

                                       20
<PAGE>

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

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

12. CERTAIN LIABILITIES

As a  Delaware  business  trust,  the  Fund's  operations  are  governed  by its
Declaration of Trust dated December 3, 1996. A copy of the Fund's Certificate of
Trust,  also dated December 3, 1996, is on file with the office of the Secretary
of State of Delaware.  Generally,  Delaware business trust  shareholders are not
personally  liable for obligations of the Delaware business trust under Delaware
law.  The Delaware  Business  Trust Act (the  "Delaware  Act")  provides  that a
shareholder  of a  Delaware  business  trust  shall  be  entitled  to  the  same
limitation  of  liability   extended  to  shareholders  of  private   for-profit
corporations.  The Fund's  Declaration of Trust expressly provides that the Fund
is organized  under the Delaware Act and that the  Declaration of Trust is to be
governed by Delaware law. It is nevertheless  possible that a Delaware  business
trust,  such as the Fund,  might  become a party to an action in  another  state
whose  courts  refused  to  apply  Delaware  law,  in  which  case  the  trust's
shareholders could become subject to personal liability.

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

                                       21
<PAGE>

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.  LETTER OF INTENT (Class A Shares Only)

   
The use of the Letter of Intent ("LOI")  procedure may be limited for this Fund.
A Letter of Intent may,  however,  be used in  connection  with the purchases of
shares of other Pioneer mutual funds.  See "How to Purchase Fund Shares - Letter
of Intent" in the Prospectus for more information.
    

Purchases  in the Class A shares of the Fund of $50,000 or more  (excluding  any
reinvestments  of  dividends  and  capital  gains  distributions)  made within a
13-month  period  pursuant to a LOI  provided by PFD will  qualify for a reduced
sales  charge.  Such  reduced  sales  charge  will be the  charge  that would be
applicable to the purchase of all Class A shares  purchased during such 13-month
period pursuant to a LOI had such shares been purchased all at once. See "How to
Buy Fund Shares" in each Prospectus.

For example,  a person who signs a LOI providing for a total investment in Class
A shares of $50,000  over a 13-month  period would be charged at the 4.50% sales
charge rate with respect to all purchases during that period.  Should the amount
actually  purchased  during  the  13-month  period  be more or  less  than  that
indicated in the LOI, an adjustment in the sales charge will be made. A purchase
not made pursuant to a LOI may be included thereafter if the LOI is filed within
90 days of such  purchase.  Any  shareholder  may also obtain the reduced  sales
charge by including the value (at current  offering  price) of all the shares of
record he holds in the Fund and in all other Pioneer mutual funds as of the date
of the LOI as a credit toward  determining the applicable  scale of sales charge
for the Class A shares to be purchased under the LOI.

A LOI 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 13-month total purchases less  redemptions,  exceed the amount  specified
under the LOI and are in an amount  which would  qualify for a further  quantity
discount,  all transactions will be recomputed on the expiration date of the LOI
to effect the lower sales charge.  Any difference in the sales charge  resulting
from such  recomputation  will be either delivered to you in cash or invested in
additional shares at the lower sales charge.  The dealer, by signing the Account
Application,  agrees to return to PFD, as part of such  retroactive  adjustment,
the excess of the  commission  previously  reallowed  or paid to the dealer over
that which is applicable to the actual amount of the total  purchases  under the
LOI.

                                       22
<PAGE>

If the  13-month  total  purchases  less  redemptions,  are less than the amount
specified under the LOI, you must remit to PFD any difference  between the sales
charge on the amount actually  purchased and the amount originally  specified in
the LOI 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.

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. Periodic payments of $50 or more will be deposited monthly or
quarterly  directly  into a bank account  designated by the applicant or will be
sent by check to the applicant,  or any person  designated by the  applicant.  A
designation of a third party to receive checks  subsequent to opening an account
requires an acceptable signature guarantee. Withdrawals under a SWP from Class B
share  accounts  are  limited to 10% of the value of the account at the time the
SWP is implemented.
    

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  SWP  account.   Redemptions  are  taxable   transactions  to
shareholders.  In  addition,  the amounts  received by a  shareholder  cannot be
considered  as 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 SWP have been redeemed.

15.  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 New York  Stock  Exchange  (the  "Exchange")
(normally 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 that the current net
asset  value per share might be  materially  affected by changes in the value of
its  portfolio  securities.  The Fund is not required to determine its net asset
value per share on any day in which no  purchase  orders  for the  shares of the
Fund become effective and no shares are tendered for redemption.
    

                                       23
<PAGE>

The net asset  value per share of each class of the Fund is  computed  by taking
the value of all of the Fund's assets  attributable to a class,  less the Fund's
liabilities  attributable  to  a  class,  and  dividing  it  by  the  number  of
outstanding  shares of the class.  For purposes of determining  net asset value,
expenses of the classes of the Fund are accrued daily.

Securities that have not traded on the date of valuation or securities for which
sales prices are not generally  reported are valued at the mean between the last
bid and asked  prices.  Securities  for which no market  quotations  are readily
available  (excluding  those whose trading has been suspended) will be valued at
fair value as  determined  in good faith by the Board of Trustees,  although the
actual  computations  may be made by persons acting pursuant to the direction of
the Board of Trustees.

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 shares
are  offered at net asset  value  without  the  imposition  of an initial  sales
charge.

16. INVESTMENT RESULTS

Quotations, Comparisons, and General Information

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

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, 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 any  such  publication)  or  used  for  comparison,  as  well  as
performance listings and rankings from various other sources including Bloomberg
Financial Markets, CDA/Wiesenberger,  Donoghue's Mutual Fund Almanac, Investment
Company  Data,  Inc.,  Johnson's  Charts,  Kanon  Bloch  Carre  and Co.,  Lipper
Analytical  Services,  Inc.,  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 shareholders of the Fund.

The Fund may also present, from time to time,  historical  information depicting
the value of a  hypothetical  account  in one or more  classes of the Fund since
such Fund's inception.

                                       24
<PAGE>

In  presenting  investment  results,  the Fund may also  include  references  to
certain  financial  planning  concepts,  including  (a) an  investor's  need  to
evaluate his financial  assets and  obligations to determine how much to invest;
(b) his need to analyze the objectives of various investments to determine where
to invest;  and (c) his need to analyze his time frame for future  capital needs
to determine how long to invest. The investor controls these three factors,  all
of which affect the use of investments in building assets.

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

The Fund's  average  annual total return  quotations  for each of its classes as
that  information  may  appear  in the  Fund's  Prospectus,  this  Statement  of
Additional  Information  or in advertising  are  calculated by standard  methods
prescribed by the Commission.

Standardized Average Annual Total Return Quotations

Average  annual  total  return  quotations  for Class A and  Class B shares  are
computed  by finding the average  annual  compounded  rates 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 $1,000, less the maximum 
                    sales load of $57.50 for Class A shares or the deduction of 
                    the CDSC for Class B shares at the end of the period.

       T   =        average annual total return

       n   =        number of years

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

For  purposes of the above  computation,  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%.

                                       25
<PAGE>

In determining the average annual total return  (calculated as provided  above),
recurring  fees,  if any,  that are  charged to all  shareholder  accounts  of a
particular  class 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 a class's  mean
account size.

   
The total  returns  for each  Class of Fund  shares as of May 31,  1997,  are as
follows:

                           Average Total Return (%)*

                                           Life of Fund
Class A Shares                                  -1.26%
Class B Shares                                   0.73%

                             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 U.S.;
prior to March 1957 it consisted of 90 of the largest stocks.
    

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

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.

                               INDEX DESCRIPTIONS

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.

                               INDEX DESCRIPTIONS

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

Item 27. Indemnification

                  Except  for the  Agreement  and  Declaration  of Trust,  dated
December 3, 1996,  establishing  the  Registrant as a trust under  Delaware law,
there is no contract,  arrangement or statute under which any director, officer,
underwriter or affiliated  person of the  Registrant is insured or  indemnified.
The Declaration of Trust provides that no Trustee or officer will be indemnified
against any  liability  of which the  Registrant  would  otherwise be subject by
reason of or for willful  misfeasance,  bad faith,  gross negligence or reckless
disregard of such person's duties.

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

Item 31. Management Services

                  The  Registrant  is  not a  party  to  any  management-related
