</TABLE>

(+) Class B shares are a new class of shares, first offered on April 28, 1995 

(1) Purchases of $1,000,000 or more and purchases by participants in certain 
    group plans are not subject to an initial sales charge but may be subject 
    to a contingent deferred sales charge as further described under "How to 
    Sell Fund Shares." 

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

(3) For Class B shares, operating expenses are based on estimated expenses 
    that would have been incurred during the previous fiscal year had Class B 
    shares been outstanding. 

 Example: 

   You would pay the following dollar amounts on a $1,000 investment in the 
Fund, assuming 5% annual return and redemption at the end of each of the time 
periods: 

                        1 Year    3 Years    5 Years     10 Years 
Class A Shares           $72        $101       $133       $ 223 
Class B Shares 
- --Assuming complete 
  redemption at end 
  of period              $62        $ 99       $138       $236* 
- --Assuming no 
  redemption             $22        $ 69       $118       $236* 

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

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

   The example is designed for information purposes only, and should not be 
considered a representation of 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, including information regarding the basis upon which 
management fees and 12b-1 fees are paid, 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 imposition of a Rule 
12b-1 fee may result in long-term shareholders indirectly paying more than 
the economic equivalent of the maximum sales charge permitted under the Rules 
of Fair Practice of the National Association of Securities Dealers, Inc. 
("NASD"). 

   The maximum 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 Fund Shares."

III. INVESTMENT OBJECTIVE, POLICIES AND RISKS 

   The investment objective of the Fund is to obtain appreciation of capital. 
The Fund invests in common stocks, together with preferred stocks, bonds and 
debentures which are convertible into common stocks. Current income will be 
incidental to the Fund's primary objective. In selecting securities for 
investment, the investment adviser attempts to identify companies that have 
better-than-average earnings growth potential and those industries that stand 
to enjoy the greatest benefit from the predicted economic environment. The 
Fund seeks to purchase the securities of companies that are thought to be 
best situated in those industry groupings. The Fund invests in companies in a 
variety of industries in an attempt to reduce its overall exposure to 
investment and market risks. 

   In pursuing its objective, the Fund purchases portfolio securities with 
the view of retaining them on a long-term basis. However, in the constant 
review of individual securities, the market and general economic conditions, 
the Fund may sell any security without regard to the period of time it has 
been held. Such sales may cause the Fund's portfolio turnover rate to exceed 
100% and may cause it to incur greater brokerage commissions than would 
otherwise be the case. 

   Part or all of the Fund's assets may be temporarily invested in securities 
of the U.S. government, its agencies or instrumentalities, commercial paper, 
bank certificates of deposit and time deposits, bankers' acceptances, other 
fixed income securities and repurchase agreements with banks and 
broker-dealers with respect to any of the foregoing instruments. At times, 
the investment adviser believes that such investments are desirable due to 
present or anticipated market or economic conditions which are affecting or 
could affect the values of the Fund's investments, as well as for liquidity 
purposes or as a temporary investment pending investment in primary 
securities. The Fund may invest in lower rated or unrated securities. These 
securities involve greater risks of default and price fluctuations due to 
credit, economic, liquidity and market concerns. 

Restricted and Illiquid Securities 

   The Fund may purchase securities that are not registered or are offered in 
an exempt non-public offering ("restricted securities") under the Securities 
Act of 1933 ("1933 Act"), including securities eligible for resale to 
"qualified institutional buyers" in accordance with Rule 144A under the 1933 
Act. However, the Fund will not invest more than 15% of its net assets in 
illiquid investments, which includes repurchase agreements maturing in more 
than seven days, securities that are not readily marketable and restricted 
securities, unless the Board of Trustees of the Fund determines, based upon a 
continuing review of the trading markets for the specific restricted 
security, that such restricted security eligible for resale in accordance 
with Rule 144A is liquid. The Board of Trustees of the Fund may adopt 
guidelines and delegate to the investment adviser the daily function of 
determining and monitoring the liquidity of restricted securities. The Board 
of Trustees, however, will retain sufficient oversight and be ultimately 
responsible for the determinations. Since it is not possible to predict with 
assurance exactly how the market for restricted securities eligible for 
resale pursuant to Rule 144A will continue to develop, the Board of Trustees 
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. 

   The purchase price and subsequent valuation of restricted securities 
normally reflect a discount from the price at which such securities trade 
when they are not restricted to the extent that the restriction makes them 
less liquid. The amount of the discount from the prevailing market price is 
expected to vary depending upon the type of security, the character of the 
issuer, the party who will bear the expenses of registering the restricted 
securities and prevailing supply and demand conditions. 

Foreign Securities 

   The Fund may invest up to 30% of its assets at the time of investment in 
listed and unlisted foreign securities. While such investments are intended 
to reduce risk by permitting greater diversification of the Fund's 
portfolios, investments in securities of foreign issuers entail certain risks 
not associated with investments in domestic issuers. Such risks include 
fluctuations in foreign currency exchange rates; possible expropriation or 
nationalization of foreign companies; imposition of exchange control 
regulations; currency blockage or dividends or interest withheld at the 
source; unfavorable price spreads on currency exchanges; higher transaction 
costs; less public information about issuers of securities; lack of uniform 
auditing, accounting and financial reporting standards; less governmental 
regulation of foreign stock exchanges and brokers; less liquidity and greater 
volatility of securities of foreign companies; or imposition of foreign 
taxes. Therefore, the Fund intends to invest primarily in the companies 
organized under the laws of those nations which are considered to have 
relatively stable and friendly governments, e.g., major industrialized 
nations such as the United Kingdom, France, Canada, Germany and Japan. 

Lending of Portfolio Securities 

   The Fund may seek to increase its income by lending portfolio securities, 
provided that the value of the securities loaned would not exceed one-third 
of the value of the total assets of the Fund. Under present regulatory 
policies, such loans may be made to institutions, such as certain 
broker-dealers, and are required to be secured continuously by collateral in 
cash, cash equivalents, or U.S. government securities maintained on a current 
basis in an amount at least equal to the market value of the securities 
loaned. The Fund may experience loss or delay in the recovery of its 
securities if the institution with which it has engaged in a portfolio loan 
transaction breaches its agreement with the Fund. 

                                      4 
<PAGE>

When Issued Securities 

   The Fund may also purchase and sell securities on a "when issued" and 
"delayed delivery" basis. These transactions are subject to market 
fluctuation; the value at the time of delivery may be more or less than the 
purchase price. Since the Fund will rely on the buyer or seller, as the case 
may be, to consummate the transaction, failure by the other party to complete 
the transaction may result in the Fund missing the opportunity of obtaining a 
price or yield considered to be advantageous. No interest accrues to the Fund 
prior to delivery. When the Fund is the buyer in such a transaction, however, 
it will maintain, in a segregated account with its custodian, cash, U.S. 
government securities, or high-grade, liquid debt obligations having an 
aggregate value equal to the amount of such purchase commitments until 
payment is made. The Fund will make commitments to purchase securities on 
such basis only with the intention of actually acquiring these securities, 
but the Fund may sell such securities prior to the settlement date if such 
sales are considered to be advisable. To the extent the Fund engages in "when 
issued" and "delayed delivery" transactions, it will do so for the purpose of 
acquiring securities for the Fund's portfolio consistent with the Fund's 
investment objective and policies and not for the purpose of investment 
leverage. 

Repurchase Agreements 

   A repurchase agreement is an instrument under which the purchaser acquires 
ownership of the obligation but the seller agrees, at the time of sale, to 
repurchase the obligation at a mutually agreed upon time and price. The 
resale price is in excess of the purchase price and reflects an agreed upon 
market rate unrelated to the coupon rate on the purchased security. Such 
transactions afford an opportunity for the Fund to invest temporarily 
available cash. In the event of the insolvency of the seller, or an order to 
stay execution of an agreement by a court or regulatory authority, the Fund 
could incur costs before being able to sell the underlying obligations and 
the Fund's realization of the underlying obligations could be delayed or 
limited, which could adversely affect the price the Fund receives for such 
obligations. There is also a risk that the seller may fail to repurchase the 
underlying obligations in which case the Fund may incur possible disposition 
costs and a loss if the proceeds of the sale of such obligations to a third 
party are less than the repurchase price. To guard against these 
possibilities, the investment adviser, under guidelines established by the 
Fund's Board of Trustees, will evaluate the creditworthiness of the seller. 
The Fund will enter into repurchase agreements only with those institutions 
that the investment adviser believes present minimal credit risks and which 
furnish collateral at least equal in value or market price to the amount of 
the repurchase obligations. Repurchase agreements maturing in more than seven 
days are considered by the Fund to be illiquid. 

Risk Factors 

   Because prices of securities fluctuate from day to day, the value of an 
investment in the Fund will vary based upon the Fund's investment 
performance. The value of your shares in the Fund may, at any time, be higher 
or lower than your original cost. The Fund may invest in debt securities with 
varying maturities. In general, the longer the maturity of a security, the 
higher the yield and the greater the potential for price fluctuations. A 
decline in interest rates generally produces an increase in the value of debt 
securities in the Fund's portfolio, while an increase in interest rates 
usually reduces the value of these securities. 

Additional Restrictions 

   In addition to the investment objective and policies discussed above, the 
Fund's investments are subject to other restrictions which are described in 
its Statement of Additional Information. Unless otherwise stated, the Fund's 
investment objective and restrictions are considered fundamental and cannot 
be changed without shareholder approval. Unless expressly designated as a 
fundamental policy, the Fund's investment policies may be changed without 
shareholder approval by the Board of Trustees of the Fund. 

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 eight Trustees, 
six of whom are not "interested persons" of the Fund as defined in the 
Investment Company Act of 1940 (the "1940 Act"). The Board meets at least 
quarterly. By virtue of the functions performed by Pioneering Management 
Corporation ("PMC") as investment adviser, the Fund requires no employees 
other than its executive officers, all of whom receive their compensation 
from PMC or other sources. The Statement of Additional Information contains 
the names of and general background information regarding each Trustee and 
executive officer of the Fund. 

   Each domestic equity portfolio managed by PMC, including the Fund, is 
overseen by the Domestic Equity Portfolio Management Committee, which 
consists of PMC's most senior domestic equity professionals. The committee is 
chaired by Mr. David Tripple, PMC's President and Chief Investment Officer 
and Executive Vice President of each of the Pioneer mutual funds. Mr. Tripple 
joined PMC in 1974 and has had general responsibility for PMC's investment 
operations and specific portfolio assignments for over five years. 

   Mr. Warren J. Isabelle, Director of Research and a Vice President of PMC 
and Vice President of the Fund, was responsible for the day-to-day management 
of the Fund from December 1, 1993 through February 17, 1995. At 
that time, Mr. Isabelle assumed the role of Senior Portfolio Manager and Mr. 
Mark S. Waterhouse, Associate Portfolio Manager, assumed primary 
responsibility for the day-to-day management of the Fund. Mr. Waterhouse 
joined PMC in 1992. Prior to joining PMC, Mr. Waterhouse was an investment 
banker with Dillon, Read & Co. 

   
   The Fund is managed under a contract with PMC. PMC serves as investment 
adviser to the Fund and is responsible for the overall management of the 
Fund's business affairs, subject only to the authority of the Fund's Board of 
Trustees. PMC is a wholly owned subsidiary of The Pioneer Group, Inc. 
("PGI"), a Delaware corporation. Pioneer Funds Distributor, Inc. ("PFD"), an 
indirect wholly-owned subsidiary of PGI, is the principal underwriter of the 
Fund. Prior to December 1, 1993, 
    

                                      5 
<PAGE>
 
FMC acted as investment adviser and principal underwriter to the Fund. 

   In addition to the Fund, PMC also manages and serves as the investment 
adviser for other mutual funds and is an investment adviser to certain other 
institutional accounts. PMC's and PFD's executive offices are located at 60 
State Street, Boston, Massachusetts 02109. 

   Under the terms of its contract with the Fund, PMC provides the Fund with 
an investment program consistent with its investment objective and policies. 
PMC furnishes the Fund with office space, equipment and personnel for 
managing the affairs of the Fund. PMC also pays all expenses in connection 
with the management of the affairs of the Fund except (i) charges and 
expenses for fund accounting, pricing and appraisal services and related 
overhead, including, to the extent such services are performed by personnel 
of PMC or its affiliates, office space and facilities and personnel 
compensation, training and benefits; (ii) the charges and expenses of 
auditors; (iii) the charges and expenses of any custodian, transfer agent, 
plan agent, dividend disbursing agent and registrar appointed by the Fund; 
(iv) issue and transfer taxes chargeable to the Fund in connection with 
securities transactions to which the Fund is a party; (v) insurance premiums, 
interest charges, dues and fees for membership in trade associations and all 
taxes and corporate fees payable by the Fund to federal, state or other 
governmental agencies; (vi) fees and expenses involved in registering and 
maintaining registrations of the Fund and/or its shares with the SEC, state 
or blue sky securities agencies and foreign countries, including the 
preparation of Prospectuses and Statements of Additional Information for 
filing with the SEC; (vii) all expenses of shareholders' and Trustees' 
meetings and of preparing, printing and distributing prospectuses, notices, 
proxy statements and all reports to shareholders and to governmental 
agencies; (viii) charges and expenses of legal counsel to the Fund and the 
Trustees; (ix) distribution fees paid by the Fund in accordance with Rule 
12b-1 promulgated by the SEC pursuant to the 1940 Act; (x) 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; (xi) the cost of 
preparing and printing share certificates; and (xii) interest on borrowed 
money, if any. In addition to the expenses described above, the Fund shall 
pay all brokers' and underwriting commissions chargeable to the Fund in 
connection with securities transactions to which the Fund is a party. 

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

   As compensation for its management services for the Fund and certain 
expenses which PMC incurs, PMC is entitled to a management fee from the Fund 
at the annual rates set forth below as a percentage of average daily net 
assets: 

                       Net Assets                           Annual Fee 
- -------------------------------------------------------    ------------- 
For assets up to $250,000,000                                   .50% 
For assets in excess of $250,000,000 to $300,000,000            .48% 
Over $300,000,000                                               .45% 

   PMC has agreed that until December 1, 1995, its fee shall not exceed the 
fee that would have been payable under the prior management contract with 
FMC. See the Statement of Additional Information for a discussion of the fee 
payable under the prior management agreement. 

   For the fiscal year ended December 31, 1994, the Fund paid a management 
fee to PMC of $619,571. 

   John F. Cogan, Jr., Chairman and President of the Fund, Chairman of PFD, 
President and a Director of PGI and Chairman and a Director of PMC, owned 
approximately 15% of the outstanding capital stock of PGI as of March 31, 
1995. 

V. FUND SHARE ALTERNATIVES 

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

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

   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. If you are making an investment that 
qualifies for reduced sales charges, you might consider Class A shares. If 
you prefer not to pay an initial sales charge on an investment of $250,000 or 
less and you plan to hold the investment for at least six years, you might 
consider Class B shares. 

   Investment dealers or their representatives may receive different 
compensation depending on which Class of shares they sell. Shares may be 
exchanged only for shares of the 

                                      6 
<PAGE>
 
same Class of another Pioneer mutual fund and shares acquired in the exchange 
will continue to be subject to any CDSC applicable to the shares of the Fund 
originally purchased. Shares sold outside the U.S. to persons who are not 
U.S. citizens may be subject to different sales charges, CDSCs and dealer 
compensation arrangements in accordance with local laws and business 
practices. 

VI. SHARE PRICE 

   Shares of the Fund are sold at the public offering price, which is the net 
asset value per share plus the applicable sales charge. Net asset value per 
share of 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 New York Stock Exchange (the "Exchange") is open, as of the 
close of regular trading on the Exchange. 

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

VII. HOW TO BUY FUND SHARES 

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

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

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

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

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

Class A Shares 

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

                                   Sales Charge as a % of

   No sales charge is payable at the time of purchase on investments of 
$1,000,000 or more or for participants in certain group plans (described 
below) subject to a CDSC of 1% which may be imposed in the event of a 
redemption of Class A shares within 12 months of purchase. See "How to Sell 
Fund Shares." PFD may, in its discretion, pay a commission to broker-dealers 
who initiate and are responsible for such purchases as follows: 1% on the 
first $5 million invested; 0.50% on the next $45 million; and 0.25% on the 
excess over $50 million. 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 
    

                                      7 
<PAGE>
 
previous 12 calendar months. Broker-dealers who receive a commission in 
connection with Class A share purchases at net asset value by 401(a) or 
401(k) retirement plans with 1,000 or more eligible participants or with at 
least $10 million in plan assets will be required to return any commission 
paid or a pro rata portion thereof if the retirement plan redeems its shares 
within 12 months of purchase. See also "How to Sell Fund Shares." In 
connection with PGI's acquisition of FMC 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. 

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

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

   Class A shares of the Fund may also be sold at net asset value per share 
without a sales charge to: (a) current or former Trustees and officers of the 
Fund and partners and employees of its legal counsel; (b) current or former 
directors, officers, employees or sales representatives of PGI or its 
subsidiaries; (c) current or former directors, officers, employees or sales 
representatives of any subadviser or predecessor investment adviser to any 
investment company for which PMC serves as investment adviser, and the 
subsidiaries or affiliates of such persons; (d) current or former officers, 
partners, employees or registered representatives of broker-dealers which 
have entered into sales agreements with PFD; (e) members of the immediate 
families of any of the 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 for Class A shares are available through an 
agreement to purchase a specified quantity of Fund shares over a designated 
13-month period by completing the "Letter of Intention" section of the 
Account Application. Information about the Letter of Intention procedure, 
including its terms, is contained in the Statement of Additional Information. 
Investors who are clients of a broker-dealer with a current sales agreement 
with PFD may purchase Class A shares of the Fund at net asset value, without 
a sales charge, to the extent that the purchase price is paid out of proceeds 
from one or more redemptions by the investor of shares of certain other 
mutual funds. In order for a purchase to qualify for this privilege, the 
investor must document to the broker-dealer that the redemption occurred 
within the 60 days immediately preceding the purchase of Class A shares; that 
the client paid a sales charge on the original purchase of the shares 
redeemed; and that the mutual fund whose shares were redeemed also offers net 
asset value purchases to redeeming shareholders of any of the Pioneer mutual 
funds. Further details may be obtained from PFD. 

Class B Shares 

   
   You may buy Class B shares at net asset value 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 long- 

                                      8 
<PAGE>
 
est during the six-year period. As a result, you will pay the lowest possible 
CDSC. 

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

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

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

Waiver or Reduction of Contingent Deferred Sales Charge 

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

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

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

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. 

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 

                                      9 
<PAGE>
 
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: 

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

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

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

In Writing 

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

   * you wish to sell over $50,000 worth of shares, 

   * your account registration or address has changed within the last 30 
     days, 

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

   * the check is not being made out to the account owners, or 

   * the sale proceeds are being transferred to a Pioneer 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, Pioneer will send the proceeds of the 
sale to the address of record. Fiduciaries or corporations are required to 
submit additional documents. For more information, contact PSC at 
1-800-225-6292. 

   Written requests will not be processed until they are received in good 
order and accepted by PSC. Good order means that there are no outstanding 
claims or requests to hold redemptions on the account, 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 indicated otherwise on your 
Account Application or by writing to the Fund. You may redeem up to $50,000 
of your shares by telephone or fax and receive the proceeds by check or bank 
wire or electronic funds transfer. To receive the proceeds by check: the 
check must be made payable exactly as the account is registered and the check 
must be sent to the address of record which must not have changed in the last 
30 days. To receive the proceeds by bank wire or by electronic funds 
transfer: the proceeds must be sent to your bank address of record which must 
have been properly pre-designated either on your Account Application or on an 
Account Options Form and which must not have changed in the last 30 days. To 
redeem by fax send your redemption request to 1-800-225-4240. The telephone 
redemption option is not available to retirement plan accounts. 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 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 $1,000,000 or more, 
or by participants in a Group Plan which were not subject to an initial sales 
charge, may be subject to a CDSC upon redemption. A CDSC is payable to PFD on 
these investments in the event of a share redemption within 12 months 
following the share purchase, at the rate of 1% of the lesser of the value of 
the shares redeemed (exclusive of reinvested dividend and capital gain 
distributions) or the total cost of such shares. Shares subject to the CDSC 
which are exchanged into another Pioneer mutual fund will continue to be 
subject to the CDSC until the original 12-month period expires. However, no 
CDSC is payable upon redemption with 
    

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

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

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

IX. HOW TO EXCHANGE FUND SHARES 

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

   
    Telephone Exchanges. Your account is automatically authorized to have the 
telephone exchange privilege unless you indicated otherwise on your Account 
Application or by writing to the 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, will be recorded. You are strongly urged to consult 
with your financial representative prior to requesting a telephone exchange. 
See "Telephone Transactions and Related Liabilities" below. 

    Automatic Exchanges. You may automatically exchange shares from one 
Pioneer mutual fund account for shares of the same Class in another Pioneer 
mutual fund account on a monthly or quarterly basis. The accounts must have 
identical registrations and the originating account must have a minimum 
balance of $5,000. The exchange will be effective on the 18th day of the 
month. 

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

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

   Exchange requests received by PSC before 4:00 p.m. Eastern Time will be 
effective on that day if the requirements above have been met, otherwise, 
they will be effective on the next business day. PSC will process exchanges 
only after receiving an exchange request in good order. There are currently 
no fees or sales charges imposed at the time of an exchange. An exchange of 
shares may be made only in states where legally permitted. For federal and 
(generally) state income tax purposes, an exchange is considered to be a sale 
of the shares of the Fund exchanged and a purchase of shares in another 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. To prevent abuse of the exchange privilege to the 
detriment of other Fund shareholders, the Fund and PFD reserve the right to 
limit the number and/or frequency of exchanges and/or to charge a fee for 
exchanges. The exchange privilege may be changed or discontinued and may be 
subject to additional limitations, including certain restriction on purchases 
by market timer accounts. 

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. 

   Pursuant to the Class A Plan, the Fund reimburses PFD for its actual 
expenditures to finance any activity primarily intended to result in the sale 
of Class A shares or to provide services to holders of Class A shares, 
provided the categories of expenses for which reimbursement is made are 
approved by the Fund's Board of Trustees. As of the date of this Prospectus, 
the Board of Trustees has approved the following categories of expenses for 
Class A shares of the Fund: (i) a service fee to be paid to qualified 
broker-dealers in an amount not to exceed 0.25% per annum of the Fund's 
average 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 aver- 

                                      11 
<PAGE>
 
age daily net assets attributable to Class A shares. Distribution expenses of 
PFD are expected to substantially exceed the distribution fees paid by the 
Fund in a given year. The Class A Plan may not be amended to increase 
materially the annual percentage limitation of average net assets which may 
be spent for the services described therein without approval of the 
shareholders of the Fund. 

   The Class B Plan provides that the Fund will pay a distribution fee at the 
annual rate of 0.75% of the Fund's average daily net assets attributable to 
Class B shares and will pay PFD a service fee at the annual rate of 0.25% of 
the Fund's average daily net assets attributable to 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. 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 has elected to be treated, has qualified, and intends to qualify 
each year as a "regulated investment company" under Subchapter M of the Code, 
so that it will not pay federal income taxes on income and capital gains 
distributed to shareholders at least annually. 

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

   The Fund's policy is to pay to shareholders dividends from net investment 
income, if any, 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; distributions from income and/or 
capital gains may also be made at such times as may be necessary to avoid 
federal income or excise tax. Dividends from the Fund's net investment 
income, net short-term capital gains, and certain net foreign exchange gains 
are taxable as ordinary income, and dividends from the Fund's net long-term 
capital gains are taxable as long-term capital gains. 

   Unless shareholders specify otherwise, all distributions will be 
automatically reinvested in additional full and fractional shares of the 
Fund. For federal income tax purposes, all dividends are taxable as described 
above whether a 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" and "Directed Dividends" below. 

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

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

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

XII. SHAREHOLDER SERVICES 

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

shareholders as transactions occur, except Automatic Investment Plan 
transactions which are confirmed quarterly. The Combined Account Statement, 
mailed quarterly, is available to shareholders who have more than one Pioneer 
account. 

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

Additional Investments 

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

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

Automatic Investment Plans 

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

Financial Reports and Tax Information 

   As a shareholder, you will receive financial reports at least 
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. 

Directed Dividends 

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

Direct Deposit 

   If you have elected to take distributions, whether dividends or dividends 
and capital gains, in cash, or have established a Systematic Withdrawal Plan, 
you may choose to have those cash 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 indicated otherwise on your Account Application or by 
writing to the PSC. You may purchase, sell or exchange Fund shares by 
telephone. See "Share Price" for more information. For personal assistance, 
call 1-800-225-6292 between 8:00 a.m. and 8:00 p.m. Eastern Time on weekdays. 
Computer-assisted transactions may be available to shareholders who have 
pre-recorded certain bank information (see "FactFone(SM)"). You are strongly 
urged to consult with your financial representative prior to requesting any 
telephone transaction. To confirm that each transaction instruction received 
by telephone is genuine, the Fund will record each telephone transaction, 
require the caller to provide the personal identification number ("PIN") for 
the account and send you a written confirmation of each telephone 
transaction. Different procedures may apply to accounts that are registered 
to non-U.S. citizens or that are held in the name of an institution or in the 
name of an investment broker-dealer or other third party. If reasonable 
procedures, such as those described above, are not followed, the Fund may be 
liable for any loss due to unauthorized or fraudulent instructions. The Fund 
may implement other procedures from time to time. In all other cases, neither 
the Fund, PSC or PFD will be responsible for the authenticity of instructions 
received by telephone, therefore, you bear the risk of loss for unauthorized 
or fraudulent telephone transactions. 
    

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

   
FactFone(SM) 

   FactFone is an automated inquiry and telephone transaction system 
available to Pioneer shareholders by dialing 1-800-225-4321. FactFone 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 
    
                                      13 
<PAGE>
 
   
mutual funds. In addition, you may use FactFone to make computer-assisted 
telephone purchases, exchanges and redemptions from your Pioneer accounts if 
you have activated your PIN. Telephone purchases and redemptions require the 
establishment of a bank account of record. You are strongly urged to consult 
with your financial representative prior to requesting any telephone 
transaction. Shareholders whose accounts are registered in the name of a 
broker-dealer or other third party may not be able to use FactFone. See "How 
to Buy Fund Shares," "How to Exchange Fund Shares," "How to Sell Fund Shares" 
and "Telephone Transactions and Related Liabilities." Call PSC for 
assistance. 
    

Retirement Plans 

   You should 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 the Fund. The Pioneer Mutual Funds Account 
Application accompanying this Prospectus should not be used to establish any 
of these plans. Separate applications are required. 

Telecommunications for the Deaf (TDD) 

   If you have a hearing disability and your own TDD keyboard equipment, you 
can call our TDD number toll-free at 1-800-622-1997, 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 shares accounts are limited to 10% of the 
value of the account at the time the plan is implemented. See "Waiver or 
Reduction of Contingent Deferred Sales Charge" for more information. Periodic 
checks of $50 or more will be sent to you, or any person designated by you, 
monthly or quarterly, and your periodic redemptions of shares may be taxable 
to you. If you direct that withdrawal checks be paid to another person after 
you have opened your account, a signature guarantee must accompany your 
instructions. Purchases of Class A shares of the Fund at a time when you have 
a SWP in effect may result in the payment of unnecessary sales charges and 
may therefore be disadvantageous. You may obtain additional information by 
calling PSC at 1-800-225-6292 or by referring to the Statement of Additional 
Information. 
    

Reinstatement Privilege (Class A Shares Only) 

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

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

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

XIII. THE FUND 

   The Fund, an open-end management investment company (commonly referred to 
as a mutual fund), was established as a Nebraska corporation on January 16, 
1968 and reorganized as a Delaware business trust on June 30, 1994. 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 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 new 
series, into one or more classes. As of the date of this Prospectus, the 
Trustees have authorized the issuance of two classes of shares, designated as 
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 
outstanding shares of the series or class to which such action relates, shall 
join in the request for the Trustees to commence such action; and (b) the 
Trustees must be afforded a reasonable amount of time to consider such 
shareholder 

                                      14 
<PAGE>
 
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 certificates. 

XIV. INVESTMENT RESULTS 

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

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

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

   The Fund's investment results will be calculated separately for each class 
of shares and will vary from time to time depending on market conditions, the 
composition of the Fund's portfolio, operating expenses of the Fund and 
expenses attributed to a specific class of Fund shares. 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.

<PAGE>


    1.        INVESTMENT OBJECTIVE AND POLICIES

              See "Investment Objective and Policies" in the Prospectus for more
    information concerning the investment objective and policies of the Fund.

    Restricted and Illiquid Securities

              In determining the liquidity of Rule 144A  securities,  the Fund's
    officers, under guidelines established by the Fund's Board of Trustees, will
    consider:  (1) the unregistered nature of a Rule 144A security;  and (2) any
    relevant  factors  related to the  marketability  of the Rule 144A security,
    which may include:  (a) the frequency of trades and quotes for the security;
    (b) the number of dealers  willing to purchase or sell the  security and the
    number of other  potential  purchasers;  (c) the  willingness  of dealers to
    undertake  to make a  market  in the  security;  and (d) the  nature  of the
    marketplace  trades,  including  the time needed to dispose of the security,
    the method of soliciting offers, and the mechanics of transfer.

              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.

    Lower Quality Debt Obligations

              The Fund may invest up to 5% of its net assets in debt  securities
    which are rated in the lowest rating categories by Standard & Poor's Ratings
    Group  ("Standard  &  Poor's")  or  by  Moody's  Investors   Service,   Inc.
    ("Moody's")  (i.e.,  ratings  of BB or lower by  Standard  & Poor's or Ba or
    lower by Moody's) or, if unrated by such rating organizations, determined to
    be of  comparable  quality  by the  Fund's  investment  adviser,  Pioneering
    Management  Corporation ("PMC"). In addition,  the Fund may invest in medium
    quality debt securities (i.e.,  securities rated BBB by Standard & Poor's or
    Baa by Moodys,  or unrated  securities  determined  by the  Adviser to be of
    comparable quality).

              Bonds rated BB or Ba or below or comparable unrated securities are
    commonly referred to as "junk bonds" and are considered  speculative and may
    be questionable as to principal and interest  payments.  In some cases, such
    bonds may be highly speculative, have poor prospects for reaching investment
    standing  and be in  default.  As a result,  investment  in such  bonds will
    entail greater  speculative  risks than those  associated with investment in
    investment grade bonds (i.e., bonds rated BBB or better by Standard & Poor's
    or Baa or better by Moody's  or, if unrated  by such  rating  organizations,
    determined to be of comparable quality by PMC).

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

                                      B-2
<PAGE>

              The  secondary   market  for  junk  bond   securities,   which  is
    concentrated  in relatively few market  makers,  may not be as liquid as the
    secondary market for more highly rated  securities,  a factor which may have
    an adverse effect on the Fund's ability to dispose of a particular  security
    when necessary to meet its liquidity needs. Under adverse market or economic
    conditions,  the secondary  market for junk bond  securities  could contract
    further,  independent of any specific  adverse changes in the condition of a
    particular  issuer.  As a result,  the Fund could find it more  difficult to
    sell these  securities or may be able to sell the securities  only at prices
    lower than if such securities  were widely traded.  Prices realized upon the
    sale of such lower rated or unrated securities,  under these  circumstances,
    may be less than the prices used in calculating the Fund's net asset value.

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

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

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

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

    Portfolio Turnover Rate

              The Fund will limit portfolio  turnover to the extent  practicable
    and consistent with its investment objective and policies. In any event, the
    Fund does not  consider  the rate of  portfolio  turnover a limiting  factor
    where  management  considers  changes  necessary and as the Fund may deem it
    advisable to take  advantage of short-term  trends by purchases and sales of
    securities. The Fund's investment policy from time to time may result in the
    portfolio  turnover  being  higher than that of  investment  companies  with


                                      B-3
<PAGE>

    investment  objectives  different from that of the Fund. A higher  portfolio
    turnover rate may result in correspondingly higher transaction costs.

    2.        INVESTMENT RESTRICTIONS

              Fundamental  Investment  Restrictions.   The  Fund  considers  the
    investment  objective,  the investment policy under the caption  "Restricted
    and Illiquid  Securities",  and the following  restrictions  as  fundamental
    policies  which cannot be changed  without  approval by a "majority"  of the
    Fund's  outstanding voting securities (as defined in Section 2(a)(42) of the
    Investment  Company Act of 1940,  as amended  (the "1940 Act")) which means:
    (a) 67% or more of the  voting  securities  present  at a special  or annual
    meeting if the holders of more than 50% of the outstanding voting securities
    of the Fund are present or represented by proxy; or (b) more than 50% of the
    outstanding  voting  securities  of the Fund,  whichever is less.  All other
    investment  policies are  considered  non-fundamental  and may be changed by
    approval of the Trustees without the vote of shareholders.

    The Fund may not:

    1.  Concentrate the investment of its assets in any one industry or group of
    industries  and therefore will not invest more than 25% of its assets in any
    one industry;

    2. Purchase  securities on margin, but it may obtain such short-term credits
    as may be necessary for the clearance of purchases and sales of securities;

    3. Make short sales of securities unless at the time of such sale it owns or
    has the right to  acquire as a result of the  ownership  of  convertible  or
    exchangeable  securities,  and without the payment of further consideration,
    an equal amount of such securities  which it will retain so long as it is in
    a short  position.  At no time will more than 10% of the value of the Fund's
    assets be committed to short sales;

    4. Make loans of its assets,  except that the Fund may purchase a portion of
    an  issue  of bonds or  other  obligations  of  types  commonly  distributed
    publicly to financial  institutions,  may purchase repurchase  agreements in
    accordance with its investment objective, policies and restrictions, and may
    make  both  short-term  (nine  months or less)  and  long-term  loans of its
    portfolio  securities  to the extent of 40% of the value of the Fund's total
    assets computed at the time of making such loans;

    5. Borrow money except for  temporary or emergency  purposes in an amount up
    to 5% of the value of the Fund's assets;

    6. Act as a securities underwriter or invest in real estate,  commodities or
    commodity contracts;

    7.  Participate  on a joint or  joint-and-several  basis  in any  securities
    trading account;

    8. Purchase any security (other than obligations of the U.S. Government, its
    agencies  or  instrumentalities),  if as a result:  (a) more than 25% of the
    value of the Fund's total assets would then be invested in securities of any
    single issuer, or (b) as to 75% of the value of the Fund's total assets: (i)
    more than 5% of the value of the Fund's  total assets would then be invested
    in securities of any single issuer, or (ii) the Fund would own more than 10%
    of the voting securities of any single issuer;

                                      B-4
<PAGE>

    9. Purchase securities of any company with a record of less than three years
    continuous operation (including that of predecessors) if such purchase would
    cause the Fund's investments in such companies taken at cost to exceed 5% of
    the value of the Fund's assets, except holding companies or companies formed
    by merger,  where the operating  companies  have had at least three years of
    continuous operation;

    10.  Purchase or retain the  securities  of any issuer if the  officers  and
    trustees of the Fund or of its Investment  Adviser who own  individually  or
    beneficially  more than 1/2 of 1% of the securities of such issuer  together
    own more than 5% of the securities of such issuer;

    11. Purchase the securities of any other investment company,  except that it
    may make such a purchase as part of a merger,  consolidation  or acquisition
    of assets; or

    12. Enter into  transactions  with  officers,  trustees or other  affiliated
    persons  of the  Fund  or its  Investment  Adviser  or  Underwriter,  or any
    organization affiliated with such persons, except securities transactions on
    an agency basis at standard  commission  rates, as limited by the provisions
    of the Investment Company Act of 1940, as amended (the "1940 Act").

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

              The Fund will not invest in puts, calls, straddles, spreads or any
    combination  thereof,  nor  will it  invest  in oil,  gas or  other  mineral
    exploration  or  development  programs  or leases or  purchase  or sell real
    estate, including real estate limited partnerships.  It is not the policy of
    the Fund to invest in any company for the purpose of acquiring or exercising
    management or control of such company. In view of the risks of loss inherent
    in investing in equity securities, there is no assurance that the investment
    objective  of the  Fund  will  be  achieved  or  that  shareholders  will be
    protected from incurring any losses on their investments.

              If a percentage restriction on investment or utilization of assets
    set forth in any of the above is  adhered  to at the time an  investment  is
    made, a later  change in  percentage  resulting  from  changing  values or a
    change in the  rating  of a  portfolio  security  will not be  considered  a
    violation of policy.

              Compensation  of Officers and Trustees.  The Fund pays no salaries
    or  compensation  to any of its  officers.  The Fund pays an  annual  fee of
    $1,000,  plus  $100  per  meeting  attended,  to  each  Trustee  who  is not
    affiliated  with PMC,  PFD or PSC.  Fees  paid to  affiliated  Trustees  are
    reimbursed  to the Fund by PMC.  The Fund  pays the  Chairman  of the  Audit
    Committee an annual fee of $250 and pays each member of the Audit  Committee
    an annual fee of $200. All Trustees are reimbursed for expenses  incurred in
    attending  Trustee  and  committee  meetings.  The Fund  also pays an annual
    trustees' fee of $500 plus expenses to each Trustee affiliated with PMC, PSC
    or PFD. Any such fees and expenses paid to affiliates or interested  persons
    of PMC, PFD or PSC are reimbursed to the Fund under its Management Contract.

    the  compensation  of each  Trustee  of the Fund for the  fiscal  year ended
    December 31, 1994:

    4.        INVESTMENT ADVISER

              As  stated  in the  Prospectus,  PMC,  60  State  Street,  Boston,
    Massachusetts,  serves as the  Fund's  investment  adviser.  PMC  became the
    Fund's investment adviser on December 1, 1993. Prior to that date, Mutual of
    Omaha  Fund  Management  Company  ("FMC")  served as the  Fund's  investment
    adviser.  The  management  contract is  renewable  annually by the vote of a
    majority of the Board of Trustees of the Fund  (including  a majority of the
    Board of Trustees who are not parties to the contract or interested  persons
    of any such parties)  cast in person at a meeting  called for the purpose of
    voting on such  renewal.  This  contract  terminates  if assigned and may be
    terminated  without penalty by either party by vote of its Board of Trustees
    or a majority  of its  outstanding  voting  securities  and the giving of 60
    days' written notice.

                                      B-9
<PAGE>

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

    Net Assets......................................................Annual Rate
    ----------                                                      -----------

    For assets up to $250,000,000......................................0.50%
    For assets in excess of $250,000,000 to $300,000,000...............0.48%
    Over $300,000,000..................................................0.45%

              PMC has agreed  that  until  December  1, 1995,  its fee shall not
    exceed the fee that would have been payable  under the  previous  management
    contact with FMC, without giving effect to any expense limitation. Under the
    previous  management  contract with FMC, which was terminated on December 1,
    1993,  the Fund paid FMC a  management  fee at an annual  rate  equal to the
    following percentages of the Fund's average daily net assets:

    Net Assets......................................................Annual Rate
    ----------                                                      -----------

    For assets up to and including $100,000,000........................50%

    For assets over $100,000,000 but not over $200,000,0000............48%

    For assets over $200,000,000 but not over $300,000,000.............46%

    For assets over $300,000,000 but not over $400,000,000.............44%

    For assets over $400,000,000 but not over $500,000,000.............42%

    For assets over $500,000,000 ......................................40%


              In  addition,  PMC has  agreed  that  if in any  fiscal  year  the
    aggregate expenses of the Fund exceed the expense limitation  established by
    any state having  jurisdiction over the Fund, PMC will reduce its management
    fee to the extent required by state law. The most restrictive  state expense
    limit currently  applicable to the Fund provides that the Fund's expenses in
    any  fiscal  year may not  exceed  2.5% of the first $30  million of average
    daily net  assets,  2.0% of the next $70  million of such assets and 1.5% of
    such assets in excess of $100 million.

              The Fund paid  $495,381 in  management  fees to FMC for the fiscal
    year ended  December  31, 1992,  and  $579,249  for the period  January 1 to
    November 30, 1993.  The Fund paid $55,956 in management  fees to PMC for the
    period  December 1 through  December  31,  1993.  The Fund paid  $619,571 in
    management fees to PMC for the fiscal year ended December 31, 1994.

              Under the  previous  management  contract  with FMC, FMC agreed to
    reimburse the Fund quarterly for all expenses (excluding interest, brokerage
    commissions,  taxes and extraordinary expenses) incurred in each year by the
    Fund in excess of 1.50% of the first $30,000,000 of the Fund's average daily
    net assets  plus 1.00% of any  additional  net  assets,  up to an amount not
    exceeding its management  fees for the period for which  reimbursements,  if
    any, were made.

    5.        UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

              The Fund entered into an Underwriting Agreement with PFD. Prior to
    that date, FMC served as the Fund's principal underwriter.  The Underwriting
    Agreement  will  continue  from  year to year if  annually  approved  by the
    Trustees.  The  Underwriting  Agreement  provides that PFD will bear certain
    distribution expenses not borne by the Fund.

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

              The Fund has adopted a plan of distribution pursuant to Rule 12b-1
    under the 1940 Act with respect to Class A shares (the "Class A Plan") and a
    plan of  distribution  with  respect to 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  under
    the caption  "Distribution  Plans." 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 the  Class A  shares,  the  annual  rate of 0.25% of the  Fund's
    average daily net assets attributable to Class A shares.

              Class B Plan

              The Class B Plan  provides  that the Fund  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  for  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.

                                      B-11
<PAGE>

              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  Plans  and  the  purpose  for  which  such
    expenditures were made. In the Trustees' quarterly review of the Plans, they
    will consider the continued  appropriateness  and the level of reimbursement
    or compensation the Plans provide.

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

              The  Plans  were  adopted  by a  majority  vote  of the  Board  of
    Trustees,  including  all of the  Trustees  who are not, and were not at the
    time they voted,  "interested  persons" of the Fund,  as defined in the 1940
    Act (none of whom had or have any direct or indirect  financial  interest in
    the  operation  of the  Plans),  cast in person at a meeting  called for the
    purpose  of voting on the  Plans.  In  approving  the  Plans,  the  Trustees
    identified and considered a number of potential benefits which the Plans may
    provide.  The  Board  of  Trustees  believes  that  there  is  a  reasonable
    likelihood  that the Plans will  benefit the Fund and its current and future
    shareholders.  Under their  terms,  the Plans  remain in effect from year to
    year provided such continuance is approved  annually by vote of the Trustees
    in the manner  described  above.  The Plans may not be  amended to  increase
    materially the annual percentage  limitation of average net assets which may
    be  spent  for  the  services  described  therein  without  approval  of the
    shareholders of the Fund affected  thereby,  and material  amendments to 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  (as  defined  in the  1940  Act) of the
    outstanding voting securities of the respective Class of the Fund. Each Plan
    will  automatically  terminate in the event of its assignment (as defined in
    the 1940 Act). In the  Trustees'  quarterly  review of the Plans,  they will
    consider a Plan's continued appropriateness and the level of compensation it
    provides.

              During the fiscal year ended  December 31, 1994, the Fund incurred
    total  distribution  fees  pursuant to the Fund's  Class A Plan of $313,145.
    Distribution  fees were paid by the Fund to PFD in reimbursement of expenses
    related to servicing of shareholder  accounts and to compensate  dealers and
    sales  personnel.  No payments were made during the year ended  December 31,
    1994 by the Fund with respect to Class B Shares.

    6.        SHAREHOLDER SERVICING/TRANSFER AGENT

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

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

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

    7.        CUSTODIAN

              Brown Brothers Harriman & Co. (the "Custodian"),  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
    also provides fund  accounting,  bookkeeping  and pricing  assistance to the
    Fund.

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

    8.        PRINCIPAL UNDERWRITER

              PFD,  60  State  Street,  Boston,  Massachusetts,  serves  as  the
    principal  underwriter  for  the  Fund in  connection  with  the  continuous
    offering  of the Class A and Class B shares of each  Fund.  Under the Fund's
    previous  underwriting  agreement  with  FMC,  FMC  received  $1,316,884  in
    aggregate  underwriting  commission  for the fiscal year ended  December 31,
    1992, and $836,000 for the period from January 1, 1993 through  November 30,
    1993,  of which  $174,258 and $106,542,  respectively,  was retained by FMC.
    Under the Fund's  current  Underwriting  Agreement  with PFD,  PFD  received
    $60,000 for the period December 1 through December 31, 1993, of which $7,872
    was retained,  and $626,814 for the fiscal year ended  December 31, 1994, of
    which $78,601 was retained.

              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 a bona fide
    reorganization,   statutory   merger,  or  other  acquisition  of  portfolio
    securities  (other than municipal debt securities  issued by state political
    subdivisions  or  their  agencies  or  instrumentalities)  provided  (i) the
    securities meet the investment objectives and policies of the fund; (ii) the
    securities are acquired by the Fund for investment and not for resale; (iii)


                                      B-13
<PAGE>

    the securities are not restricted as to transfer  either by law or liquidity
    of  market;   and  (iv)  the  securities  have  a  value  which  is  readily
    ascertainable  (and  not  established  only  by  evaluation  procedures)  as
    evidenced by a listing on the American  Stock Exchange or the New York Stock
    Exchange or the Nasdaq National Market.

    9.        INDEPENDENT PUBLIC ACCOUNTANT

              Effective  January 1, 1994,  Arthur Andersen LLP (formerly  Arthur
    Andersen & Co.), One International  Place,  Boston, MA 02110 was selected as
    the  independent  public  accountant  for the  Fund.  Previously,  Coopers &
    Lybrand had served as  independent  public  accountant  to the Fund.  Arthur
    Andersen's  election as independent  public  accountant  was approved,  at a
    meeting called for the purpose of voting on such approval,  by the vote of a
    majority of those  Trustees on the Board of Trustees who are not  interested
    persons of the Fund.

    10.       PORTFOLIO TRANSACTIONS

              All orders for the  purchase or sale of portfolio  securities  are
    placed on behalf of the Fund by PMC pursuant to  authority  contained in the
    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 or who sell shares of the Pioneer  mutual  funds.  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-dealer,   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.

                                      B-14
<PAGE>

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

              In  addition  to the  Fund,  PMC  acts as  investment  adviser  or
    subadviser to the other Pioneer mutual funds,  Pioneer Interest Shares, Inc.
    and certain private accounts with investment  objectives  similar to that of
    the Fund.  Securities  frequently meet the investment objective 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 more than
    one of the Fund, another Pioneer mutual fund, Pioneer Interest Shares,  Inc.
    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.

              The  Fund  paid   brokerage   or   underwriting   commissions   of
    approximately $44,909, $131,000 and $343,317,  respectively,  for the fiscal
    years ended December 31, 1992, 1993 and 1994.

    11.       DIVIDENDS AND TAX STATUS

              The Fund's policy is to pay dividends from net  investment  income
    at least once a year and  distributions  of net realized  capital gains,  if
    any, once a year.  Additional  distributions  may be made for the purpose of
    avoiding liability for federal income or excise tax.

              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 its income,  the  diversification  of its assets,  and the
    timing of its  distributions  to  shareholders.  If the Fund  meets all such
    requirements  and  distributes to its  shareholders,  in accordance with the
    Code's timing  requirements,  all investment  company taxable income and net
    capital  gain, if any,  which it receives,  the Fund will be relieved of the
    necessity of paying federal income tax.

                                      B-15
<PAGE>

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

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

              If the Fund acquires stock in certain non-U.S.  corporations  that
    receive at least 75% of their annual gross income from passive sources (such
    as interest,  dividends,  rents, royalties or capital gain) or hold at least
    50% of their assets in investments  producing such passive income  ("passive
    foreign investment companies"),  the Fund could be subject to federal income
    tax and additional interest charges on "excess distributions"  received from
    such companies or gain from the sale of stock in such companies, even if all
    income or gain actually  received by the Fund is timely  distributed  to its
    shareholders. The Fund would not be able to pass through to its shareholders
    any credit or deduction for such a tax. Certain elections may, if available,
    ameliorate  these  adverse tax  consequences,  but any such  election  would
    require the Fund to recognize  taxable income or gain without the concurrent
    receipt of cash.  The Fund may limit  and/or  manage its holdings in passive
    foreign  investment  companies to minimize its tax liability or maximize its
    return from these investments.

                                      B-16
<PAGE>

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

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

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

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

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

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

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

                                      B-17

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

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

              Provided that the Fund qualifies as a regulated investment company
    under the Code,  it will not be  required to pay any  Massachusetts  income,
    corporate excise or franchise taxes, and, subject to compliance with certain
    income-source  requirements  under  Delaware  law,  it  should  also  not be
    required to pay Delaware corporation income tax.

              The  description  above  relates only to U.S.  federal  income tax
    consequences for shareholders who are U.S.  persons,  i.e., U.S. citizens or
    residents and U.S. domestic corporations,  partnerships,  trusts or estates,
    and who are subject to U.S.  federal  income tax. The  description  does not
    address the special tax rules  applicable  to certain  classes of investors,
    such as banks, insurance companies, or tax-exempt entities.  Investors other
    than U.S. persons may be subject to different U.S. tax treatment,  including
    a possible 30% 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  advisors on these  matters  and on state,  local and
    other applicable tax laws.

    12.       SHARES OF THE FUND

    General

              The  Fund  is an  open-end  investment  company  established  as a
    Nebraska corporation in 1968 and reorganized as a Delaware business trust in
    June 1994.  Prior to December 1, 1993,  the Fund was called  Mutual of Omaha
    Growth Fund,  Inc. and prior to June 30, 1994,  the Fund was called  Pioneer
    Growth  Shares,  Inc.  Reference  to the Fund  includes  both  the  Delaware
    business trust and the Nebraska  corporation.  The Board of Trustees,  as of
    the date of this  Statement of Additional  Information,  has  authorized the
    issuance of two classes of shares: Class A and Class B.

              Unless  otherwise  required by the 1940 Act or the  Agreement  and
    Declaration of Trust (the "Declaration of Trust"), the Fund has no intention
    of  holding  annual  meetings  of  shareholders.  Shareholders  may remove a
    Trustee  by the  affirmative  vote  of at  least  two-thirds  of the  Fund's
    outstanding  shares and the Trustees  shall promptly call a meeting for such
    purpose when requested to do so in writing by the record holders of not less
    than 10% of the  outstanding  shares of the Trust.  Shareholders  may, under
    certain circumstances communicate with other shareholders in connection with


                                      B-18
<PAGE>

    requesting a special meeting of shareholders. However, at any time that less
    than  a  majority  of  the  Trustees  holding  office  were  elected  by the
    shareholders,  the Trustees will call a special meeting of shareholders  for
    the purpose of electing Trustees.

              The  Declaration of Trust permits the issuance of series of shares
    in  addition  to the  Fund  which  would  represent  interests  in  separate
    portfolios of investments. No series would be entitled to share in the asset
    of any other  series or be liable for the  expenses  or  liabilities  of any
    other series.

              In  addition  to  the   requirements   under   Delaware  law,  the
    Declaration  of Trust  provides  that  shareholders  of the Fund may bring a
    derivative action on behalf of the Fund only if the following conditions are
    met:  (a)  shareholders  eligible  to bring  such  derivative  action  under
    Delaware law who hold at least 10% of the outstanding shares of the Fund, or
    10% of the  outstanding  shares of the series or class to which such  action
    relates, shall join in the request for the Trustees to commence such action;
    and (b) the  Trustees  must  be  afforded  a  reasonable  amount  of time to
    consider  such  shareholder  request  and to  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.

    Shareholder and Trustee Liability

              The Fund is organized as a Delaware  business  trust,  and,  under
    Delaware law, the shareholders of such a trust are not generally  subject to
    liability for the debts or obligations of the trust. Similarly, Delaware law
    provides  that the Fund will not be liable for the debts or  obligations  of
    any other  series of the  trust.  However,  no  similar  statutory  or other
    authority limiting business trust shareholder liability exists in many other
    states.  As a result,  to the  extent  that a Delaware  business  trust or a
    shareholder is subject to the  jurisdiction  of courts in such other states,
    the courts may not apply  Delaware law and may thereby  subject the Delaware
    business trust  shareholders  to liability.  To guard against this risk, the
    Declaration of Trust contains an express disclaimer of shareholder liability
    for acts or obligations of the Fund. Notice of such disclaimer will normally
    be  given  in each  agreement,  obligation  or  instrument  entered  into or
    executed by the Fund or a Trustee.  The  Declaration  of Trust  provides for
    indemnification  by the Fund for any loss  suffered  by a  shareholder  as a
    result of an obligation of the Fund. The  Declaration of Trust also provides
    that the Fund  shall,  upon  request,  assume the  defense of any claim made
    against any  shareholder  for any act or  obligation of the Fund and satisfy
    any judgment  thereon.  The Trustees believe that, in view of the above, the
    risk of personal liability of shareholders is remote.

              The  Declaration of Trust further  provides that the Trustees will
    not be liable for errors of judgment or mistakes of fact or law, but nothing
    in the  Declaration  of Trust  protects a Trustee  against any  liability to
    which he or she would otherwise be subject by reason of willful misfeasance,
    bad faith, gross negligence, or reckless disregard of the duties involved in
    the conduct of his or her office.

    13.       DETERMINATION OF NET ASSET VALUE

              The net  asset  value  per  share  of each  class  of the  Fund is
    determined as of the close of regular trading on the New York Stock Exchange
    (the  "Exchange")  (currently  4:00  p.m.,  Eastern  Time)  on each  day the
    Exchange  is  open  for  business.  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


                                      B-19
<PAGE>

    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.  On any day in which no purchase orders for the shares
    of the Fund become effective and no shares are tendered for redemption,  the
    Fund's net asset value per share may not be determined.

              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 that 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 and taken into account.

              In determining the value of the assets of the Fund for the purpose
    of obtaining the net asset value,  securities listed or traded on a national
    or foreign securities  exchange shall be valued at their last sales price on
    the day of  valuation  or, if there are no sales on that day,  at the latest
    bid quotation.  Equity securities traded over-the-counter for which the last
    sales price on the day of  valuation  is  available  shall be valued at that
    price.  All other  over-the-counter  equity  securities  for which  reliable
    quotations  are  readily  available  shall be  valued  at their  latest  bid
    quotation. Convertible securities traded over-the-counter for which reliable
    quotations are readily  available shall be valued on the basis of valuations
    furnished by pricing  services  which  utilize  electronic  data  processing
    techniques to determine the valuations for normal institutional-size trading
    units of such  securities.  Securities not valued by the pricing service for
    which reliable  quotations are readily available,  shall be valued at market
    values  furnished  by  recognized  dealers  in such  securities.  Short-term
    obligations with remaining  maturities of 60 days or less shall be valued at
    amortized  cost.  Securities and other assets for which reliable  quotations
    are not readily available, shall be valued at their fair value as determined
    in good faith under consistently applied guidelines established by and under
    the general  supervision of the Board of Trustees of the Fund,  although the
    actual  calculations may be made by persons acting pursuant to the direction
    of the Board.

              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.

    14.       SYSTEMATIC WITHDRAWAL PLAN

              The  Systematic  Withdrawal  Plan ("SWP"),  which is available for
    Class A Shares only, is designed to provide a convenient method of receiving
    fixed  payments  at  regular  intervals  from  Class A  Shares  of the  Fund
    deposited  by the  applicant  under the SWP. The  applicant  must deposit or
    purchase for deposit with PSC shares of the Fund having a total value of not
    less  than  $10,000.  Periodic  checks  of $50 or  more  will be sent to the
    applicant,  or any  person  designated  by  him,  monthly  or  quarterly.  A
    designation  of a third  party to  receive  checks  requires  an  acceptable
    signature  guarantee.  The CDSC on any shares subject to a CDSC (see "How to
    Buy  Fund  Shares"  in  the   Prospectus)  may  be  waived  or  reduced  for
    non-retirement  accounts if the redemption is made in connection  with a SWP
    (limited  in any  year to 10% of the  value of the  account  at the time the
    withdrawal plan is established).

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

                                      B-20
<PAGE>

              SWP  payments  are made from the  proceeds  of the  redemption  of
    shares  deposited  under the SWP in a SWP account.  Redemptions  are taxable
    transactions  to  shareholders.  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.  In  addition,  the  amounts  received  by a
    shareholder  cannot be considered as an actual yield or income on his or her
    investment  because  part of such  payments  may be a  return  of his or her
    investment.

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

    15.       LETTER OF INTENTION

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

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

              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 indexes or
    indicators  of  economic  activity,   e.g.,  inflation  or  interest  rates.
    Performance  rankings  and  listings  reported  in  newspapers  or  national
    business  and  financial  publications,  such as  Barron's,  Business  Week,
    Consumers  Digest,  Consumer  Reports,  Financial  World,  Forbes,  Fortune,
    Investors  Business Daily,  Kiplinger's  Personal  Finance  Magazine,  Money

              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 the Fund's inception.

              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.

              Standardized Average Annual Total Return Quotations

              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.

                                      B-22

              The Fund's average annual total return  quotations for each of its
    classes  as that  information  may  appear in the  Fund's  Prospectus  or in
    advertising are calculated by standard methods  prescribed by the Securities
    and Exchange Commission (the "SEC").

              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%. The one-,  five-,  ten-year  and  life-of-Fund
    average  annual  total  returns  for the  Class A  shares  of the Fund as of
    December 31, 1994 were -8.20%, 8.44%; 13.52% and 7.62%.

              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 the Fund's mean account size.

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

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

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

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

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

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

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


                                      B-26
<PAGE>

the beginning of each monthly holding period) a 20-year  maturity,  a bond price
equal to par,  and a  coupon  equal to the  beginning-of-period  yield.  For the
period 1926-1945, the Standard and Poor's monthly High-Grade Corporate Composite
yield data were used,  assuming a 4 percent coupon and a 20-year  maturity.  The
conventional  present-value  formula  for  bond  price  for  the  beginning  and
end-of-month  prices was used.  (This formula is presented in Ross,  Stephen A.,
and Randolph W. Westerfield,  Corporate Finance, Times Mirror/Mosby,  St. Louis,
1990, p. 97 ["Level-Coupon Bonds"].) The monthly income return was assumed to be
one-twelfth the coupon.

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

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

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

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

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