I. EXPENSE INFORMATION 
This table is designed to help you understand the charges and expenses that 
you, as a shareholder, will bear directly or indirectly when you invest in 
the Fund. The table reflects estimated expenses based on actual expenses for 
the fiscal year ended December 31, 1993, adjusted to reflect certain changes 
resulting from, among others, the approval of new management agreements with 
Pioneering Management Corporation, expressed as a percentage of average net 
assets of the Fund. 

Shareholder Transaction Expenses 
Maximum Sales Charge on Purchases(1)                              5.75% 
Maximum Sales Charge on Reinvestment of Dividends                 None 
Deferred Sales Charge(1)                                          None 
Redemption Fee(2)                                                 None 
Exchange Fee                                                      None 
Annual Fund Operating Expenses 
  (as a percentage of average net assets) 
Management Fees                                                   0.50% 
12b-1 Fees                                                        0.25% 
Other Expenses 
  (including printing expenses and transfer agent, 
  professional and registration fees)                             0.45% 
Total Operating Expenses                                          1.20% 

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

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

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

1 Year              $ 69 
3 Years*            $ 93 
5 Years*            $120 
10 Years*           $195 

*These are cumulative totals, the average annual fees and expenses paid over 
a 10-year period would be approximately $19.50 

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

The example is designed for informational purposes only, and should not be 
considered a representation of past or future expenses or return. Actual Fund 
expenses and return vary from year to year and may be higher or lower than 
those shown. 

For further information regarding management fees, 12b-1 fees and other 
expenses of the Fund, see "Management of the Fund," "Distribution Plan" and 
"How To Purchase Shares" in this Prospectus and "Management of the Fund" and 
"Underwriting Agreement and Distribution Plan" in the Statement of Additional 
Information. Because of the 12b-1 fee, a long-term investor over time may pay 
more than the economic equivalent of the maximum initial sales charge 
permitted under the Rules of Fair Practice of the National Association of 
Securities Dealers, Inc. 

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

III. INVESTMENT OBJECTIVE AND POLICIES 
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. Although it has not happened in any of the five preceding years, 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 Boards 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 Boards 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 as having 
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. 

<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. Distributions to shareholders 
of income from repurchase agreements are taxable. 

Price Fluctuation 
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 their 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 portfolio managed by PMC, including the Fund, is overseen by an 
Investment Committee (either the Equity Committee or the Fixed-Income 
Committee), both of which consist of PMC's most senior investment 
professionals. Both Committees are chaired by Mr. David Tripple, PMC's 
President and Chief Investment Officer and Executive Vice President of each 
of the Funds. Mr. Tripple joined PMC in 1974 and has had general 
responsibility for PMC's investment operations and specific portfolio 
assignments for over five years. Mr. Warren J. Isabelle is primarily 
responsible for the day-to-day management of the Fund. Mr. Isabelle joined 
PMC in 1984 and is Vice President of PMC and the Fund. 

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

<PAGE>
 
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. 

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. 

The prior management agreement with FMC was in effect until December 1, 1993 
and provided for compensation to FMC at different rates than are set forth 
above. For the fiscal year ended December 31, 1993, the Fund paid management 
fees as follows: from January 1, 1993 to November 30, 1993, $579,249 to FMC; 
from December 1, 1993 to December 31, 1993, $55,956 to PMC. 

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, 
1994. 

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

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

Expenditures of the Fund pursuant to the Plan are accrued daily and may not 
exceed 0.25% of average daily net assets. Distribution expenses of PFD are 
expected to substantially exceed the distribution fees paid by the Fund in a 
given year. The Plan does not provide for the carryover of reimbursable 
expenses beyond 12 months from the time the Fund is first invoiced for an 
expense. The limited carryover provision in the Plan may result in an expense 
invoiced to the Fund in one fiscal year being paid in the subsequent fiscal 
year and thus being treated for purposes of calculating the maximum 
expenditures of the Fund as having been incurred in the subsequent fiscal 
year. In the event of termination or non-continuance of the Plan, the Fund 
has 12 months to reimburse any expense which is incurred prior to such termi- 

<PAGE>
 
nation or non-continuance, provided that payments by the Fund during such 
12-month period shall not exceed 0.25% of the Fund's average net daily assets 
during such period. The Plan may not be amended to increase materially the 
annual percentage limitation of average net assets which may be spent for the 
services described therein without approval of the shareholders of the Fund. 

VI. INFORMATION ABOUT FUND SHARES 

HOW TO PURCHASE SHARES 
You may purchase shares of the Fund at the public offering price from any 
securities broker-dealer having a sales agreement with PFD. The minimum 
initial investment is $1,000, except for accounts being established to 
utilize monthly bank drafts, government allotments and other similar 
automatic investment plans. The minimum investment for such plans, as well as 
all other subsequent additions to an account, is $50. Separate minimum 
investment requirements apply to retirement plans. No sales charge or minimum 
investment requirements apply to the reinvestment of dividends or capital 
gains distributions. 

The public offering price of shares of the Fund is 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       Dealer 
                                                                 Allowance 
                                                      Net        as a % of 
                                      Offering      Amount        Offering 
        Amount of Purchase             Price       Invested        Price 
Less than $50,000                       5.75%        6.10%          5.00% 
$50,000 but less than $100,000          4.50%        4.71%          4.00% 
$100,000 but less than $250,000         3.50%        3.63%          3.00% 
$250,000 but less than $500,000         2.50%        2.56%          2.00% 
$500,000 but less than $1,000,000       2.00%        2.04%          1.75% 
$1,000,000 or more                      -0-          -0-           See below 

No sales charge is payable at the time of purchase on investments of 
$1,000,000 or more or on purchases by certain Group Plans, but for such 
investments a contingent deferred sales charge of 1% is imposed in the event 
of certain redemption transactions within one year of purchase. See 
"Redemptions and Repurchases" below. PFD may, in its discretion, pay a 
commission to broker-dealers who initiate and are responsible for such 
purchases as follows: 1% on the first $1 million invested; 0.50% on the next 
$4 million; and 0.10% on the excess over $5 million. These commissions shall 
not be payable if the purchaser is affiliated with the broker-dealer or if 
the purchase represents the reinvestment of a redemption made during the 
previous twelve calendar months. In connection with PGI's acquisition of FMC, 
PFD pays to a dealer previously affiliated with FMC 50% of PFD's retention of 
any sales commission on sales of the Fund's shares through such dealer 
contingent upon the achievement of certain sales objectives. 

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

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

Sales charges may also be reduced through an agreement to purchase a 
specified quantity of shares over a designated thirteen-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. 

Shares of the Fund may be sold at a reduced or eliminated sales charge to 
certain Group Plans under which a sponsoring organization makes 
recommendations to, permits group solicitation of, or otherwise facilitates 
purchases by, its employees, members or participants. Information about such 
arrangements is available from PFD. 

Shares of the Fund may also be sold at net asset value per share without a 
sales charge to: (a) current or former Directors, 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 only and may not be resold 
except through redemption or repurchase by or on behalf of the Fund. The 
availability of this privilege depends upon the receipt by PFD of written 
notification of eligibility. Shares of the Fund may also be sold at net asset 
value without a sales charge in connection with certain reorganization, 
liquidation or acquisition transactions involving other investment companies 
or personal holding companies. 

Investors who are clients of a broker-dealer with a current sales agreement 
with PFD may purchase shares of the Fund 

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

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

Securities are valued at the last sale price on the principal exchange or 
market where they are traded. Securities which have not traded on the date of 
valuation or securities for which sales prices are not generally reported are 
valued at the mean between the current bid and asked prices. Securities 
quoted in foreign currencies are converted to U.S. dollars utilizing foreign 
exchange rates employed by the Fund's independent pricing services. 
Generally, trading in foreign securities is substantially completed each day 
at various times prior to the close of regular trading on the Exchange. The 
values of such securities used in computing the net asset value are 
determined as of such times. Foreign currency exchange rates are also 
generally determined prior to the close of regular trading on the Exchange. 
Occasionally, events which affect the values of such securities and such 
exchange rates may occur between the times at which they are determined and 
the close of regular trading on the Exchange and will therefore not be 
reflected in the computation of the Fund's net asset value. If events 
materially affecting the value of such securities occur during such period, 
then these securities are valued at their fair value as determined in good 
faith in accordance with procedures established 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 in accordance with 
procedures established by the Trustees. 

An order for shares received by a broker-dealer prior to the close of regular 
trading on the Exchange (currently 4:00 p.m. Eastern Time) is confirmed at 
the offering price determined at the close of regular trading on the Exchange 
on the day the order is received, provided the order is received by PFD prior 
to PFD's close of business (normally 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. An order received by a 
broker-dealer following the close of regular trading on the Exchange will be 
confirmed at the offering price as of the close of regular trading on the 
Exchange on the next trading day. 

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

DIVIDENDS, DISTRIBUTIONS AND TAXATION 

Taxation 
The Fund has elected to be treated, has qualified, and intends to qualify 
each year as a "regulated investment company" under 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 taxable ordinary income and capital 
gains if it fails to meet certain distribution requirements by the end of the 
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 dividends from its taxable net investment income, including 
taxable interest income and original issue discount, market discount, income 
from securities lending, certain net realized foreign exchange gains, and any 
net short-term capital gains realized by the Fund are taxable to shareholders 
as ordinary income under the Code. Dividends from the Fund's net long-term 
capital gains are taxable to shareholders as long-term capital gains under 
the Code, regardless of a shareholder's holding period for his Fund shares. 
For federal income tax purposes, dividends are taxable as described above 
whether a shareholder takes them in cash or reinvests in additional shares of 
the Fund. 

Distributions by the Fund of dividend income it receives from U.S. domestic 
corporations may qualify for the dividends-received deduction for corporate 
shareholders, subject to certain minimum holding period requirements and 
debt-financing restrictions under the Code. Amounts qualifying for the 
deduction may be includable in income subject to the alternative minimum tax 
and/or may result in a reduction in the shareholder's tax basis in the Fund 
shares. 

The Fund may be subject to foreign withholding taxes with respect to interest 
or dividends payable on certain foreign securities and will not qualify to 
pass through such taxes to shareholders. However, such taxes will be 
deductible by the Fund in computing the income it is required to distribute. 

The federal income tax status of all distributions will be reported to 
shareholders annually, and taxable shareholders are required to report all 
distributions, including tax-exempt distributions, on their federal income 
tax returns. 

The Fund's taxable dividends and other taxable distributions, and the 
proceeds of redemptions, exchanges or repurchases of the Fund's shares paid 
to individuals and other non-exempt pay- 

<PAGE>
 
ees will be subject to a 31% backup federal withholding tax if the Fund is 
not provided with the shareholder's correct taxpayer identification number 
and certification that the number is correct and that the shareholder is not 
subject to such backup withholding or if the Fund receives notice from the 
IRS or a broker that backup withholding applies. 

The description above relates only to U.S. federal income tax consequences 
for shareholders who are U.S. persons, i.e. U.S. citizens or residents, or 
U.S. corporations, partnerships, trusts or estates and who are subject to 
U.S. federal income tax. It is possible that many states will exempt from 
personal income tax that portion of the Fund's dividends attributable to 
interest received by the Fund from certain U.S. Government obligations. You 
should consult your own tax adviser regarding this possibility and other tax 
consequences under state, local and other applicable tax laws. 

Dividends and Distributions 
The policy of the Fund is to pay dividends from net investment income, if 
any, annually. Net short-term capital gains distributions, if any, may be 
paid with such dividends, and other distributions of dividends and capital 
gains may also be made at such times as may be necessary to avoid federal 
income or excise tax. 

Unless shareholders specify otherwise, all distributions from the Fund will 
be automatically reinvested in additional full and fractional shares of the 
Fund. For further information on the distribution options available to 
shareholders, see "Distribution Options" and "Directed Dividends" below. 

REDEMPTIONS AND REPURCHASES 

Redemptions by Mail 
As a shareholder, you have the right to offer your shares for redemption by 
delivering to Pioneering Services Corporation ("PSC") a written request for 
redemption in proper form and, if applicable, your share certificates 
properly endorsed and in good order for transfer. Redemptions will be made in 
cash at the net asset value per share next determined following receipt by 
PSC of all necessary documents subject in certain cases to the contingent 
deferred sales charge described below. 

Good order means that there are no outstanding claims or requests to hold 
redemptions on the account, the certificates are endorsed by the record 
owner(s) exactly as the shares are registered and the signature(s) are 
guaranteed by any of the following eligible guarantor institutions: (i) all 
brokers, dealers, municipal securities dealers and/or brokers, government 
securities dealers and/or brokers, who are members of a clearing agency or 
whose net capital exceeds $100,000; (ii) all banks; (iii) all credit unions; 
(iv) all savings associations, including all savings and loan associations; 
(v) all national securities exchanges, registered securities associations, 
and all clearing agencies; and (vi) all trust companies. In addition, in some 
cases (involving fiduciary or corporate transactions), good order may require 
the furnishing of additional documents. 

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

Redemption by Telephone or Fax 
Your account is automatically authorized to have the telephone redemption 
privilege unless you indicated otherwise on your Account Application or by 
writing to PSC. Proper account identification will be required for each 
telephone redemption. The telephone redemption option is not available to 
retirement plan accounts. A maximum of $50,000 may be redeemed by telephone 
or fax and the proceeds may be received by check or by bank wire. 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: 
the wire must be sent to the bank wire address of record which must have been 
properly pre-designated either on your Account Application or on an Account 
Options Form and which must not have changed in the last 30 days. To redeem 
by fax, send your redemption request to 1-800-225-4240. You may always elect 
to deliver redemption instructions to PSC by mail. See "Telephone 
Transactions and Related Liabilities" below. Telephone redemptions will be 
priced as described above. 

Additional Conditions of Redemption 
For the convenience of shareholders, the Fund has authorized PFD to act as 
its agent in the repurchase of its shares. The Fund reserves the right to 
terminate this procedure at any time. Offers to sell shares to the Fund may 
be communicated to PFD by wire or telephone by broker-dealers for their 
customers. The Fund's practice will be to repurchase shares offered to it at 
the net asset value per share determined as of the close of business of the 
Exchange on the day the offer for repurchase is received and accepted by the 
broker-dealer if the offer is received by PFD before PFD's close of business 
on that day. Shareholders whose accounts are registered in the name of a 
broker, dealer or other financial institution must contact a representative 
of the institution holding the shares to arrange for a redemption. 

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

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

Redemption 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. 

Purchases of Fund shares of $1,000,000 or more, and purchases by participants 
in a Group Plan which have not been subject to a sales charge, may be subject 
to a contingent deferred sales charge upon redemption or repurchase. A 
contingent deferred sales charge is payable on these investments in the event 
of a share redemption within 12 months following the share purchase, at the 
rate of 1% of the lesser of the value of the shares redeemed (exclusive of 
reinvested dividend and capital gain distributions) or the total cost of such 
shares. In determining whether a contingent deferred sales charge is payable, 
and, if so, the amount of the charge, it is assumed that shares purchased 
with reinvested dividends and capital gain distributions and then such other 
shares which are held the longest will be the first redeemed. 

Waiver or Reduction of Contingent Deferred Sales Charge 
The CDSC on any shares subject to a CDSC may be waived or reduced for 
non-retirement accounts if: (a) the redemption results from the death of all 
registered owners of an account (in the case of UGMAs, UTMAs and trust 
accounts, waiver applies upon the death of all beneficial owners) or a total 
and permanent disability (as defined in Section 72 of the Code) of all 
registered owners occurring after the purchase of the shares being redeemed 
or (b) the redemption is made in connection with limited 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 any shares subject to a CDSC may be waived or reduced for 
retirement plan accounts if: (a) the redemption results from the death or a 
total and permanent disability (as defined in Section 72 of the Code) 
occurring after the purchase of the shares being redeemed of a shareholder or 
participant in an employer-sponsored retirement plan; (b) the distribution is 
to a participant in an IRA, 403(b) or employer-sponsored retirement plan, is 
part of a series of substantially equal payments made over the life 
expectancy of the participant or the joint life expectancy of the participant 
and his or her beneficiary (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; (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 any shares subject to a CDSC may be waived or reduced for either 
non-retirement or retirement plan accounts if: (a) the redemption is made by 
any state, county, or city, or any instrumentality, department, authority, or 
agency thereof, which is prohibited by applicable laws from paying a 
contingent deferred sales charge in connection with the acquisition of shares 
of any registered investment management company; or (b) the redemption is 
made pursuant to the Fund's right to liquidate or involuntarily redeem shares 
in a shareholder's account. 

Shares subject to the contingent deferred sales charge which are exchanged 
into another Pioneer fund will continue to be subject to the contingent 
deferred sales charge until the original 12-month period expires. 

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

Account and Confirmation Statements 
PSC maintains an account for each shareholder and all transactions of the 
shareholder are recorded in this account. Confirmation statements showing the 
details of transactions are sent to shareholders as transactions occur. The 
Pioneer Combined Account Statement, mailed quarterly, is available to all 
shareholders who have more than one Pioneer account. 

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

<PAGE>
 
Additional Investments 
You may add to your account by sending a check ($50 minimum) to PSC (account 
number should be clearly indicated). The bottom portion of a confirmation 
statement may be used as a remittance slip to make additional investments. 
Additions to your account, whether by check or through a Pioneer Investomatic 
Plan, are invested in full and fractional shares of the Fund at the offering 
price in effect as of the close of regular trading on the Exchange on the day 
of receipt. 

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

Financial Reports and Tax Information 
As a shareholder, you will receive financial reports at least semi-annually. 
In January of each year, the Fund will mail you information about the tax 
status of dividends and other distributions. 

Distribution Options 
Dividends and capital gains distributions, if any, will automatically be 
invested in additional shares of the Fund, at net asset value per share, 
unless you indicate another option on your Account Application. 

Two other available options are (a) dividends in cash and capital gains 
distributions in additional shares; and (b) all dividends and distributions 
in cash. The two options are not available, however, with respect to 
retirement plans or an account with a net asset value of less than $500. 
Changes in the distribution options may be made by written request to PSC. 

Directed Dividends 
You may elect (in writing) to have the dividends paid by one Pioneer 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 e.g., 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 your Account Application when opening a new 
account or an Account Options Form for an existing account. 

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

Exchange Privilege 
You may exchange your shares of the Fund at net asset value, without a sales 
charge, for shares of other Pioneer funds which do not offer different 
classes of shares or for the Class A shares of those Pioneer funds that offer 
more than one class of shares. There are currently no fees or sales charges 
on such an exchange. The exchange privilege is available only in those states 
where exchanges can legally be made. 

Exchanges must be at least $1,000. A new Pioneer account opened through an 
exchange must have a registration identical to that on the original account. 
PSC will process exchanges only after receiving an exchange request in proper 
form. Shares of the Fund acquired through exchange of shares subject to a 
contingent deferred sales charge will be subject to such charge, if 
applicable, upon redemption. 

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

 Telephone Exchanges. Your account is automatically authorized to have the 
telephone exchange privilege unless you indicated otherwise on your Account 
Application or by writing to PSC. Proper account identification will be 
required for each telephone exchange. Telephone exchanges may not exceed 
$500,000 per account per day. All telephone exchange requests will be 
recorded. 

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

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

You should consider the differences in objectives and policies of the Pioneer 
mutual funds, as described in each of the fund's current prospectus, before 
making any exchange. For federal and (generally) state income tax purposes, 
an exchange represents a sale of the shares exchanged and a purchase of 
shares in another fund. Therefore, an exchange 

<PAGE>
 
could result in a gain or loss on the shares sold, depending on the cost 
basis of these shares and the timing of the transaction, and special tax 
rules may apply. 

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. 

Telephone Transactions and Related Liabilities 
Your account is automatically authorized to have telephone transaction 
privileges unless you indicated otherwise on your Account Application or by 
writing to PSC. You may sell or exchange your Fund shares by telephone by 
calling 1-800-225-6292 between 8:00 a.m. and 8:00 p.m. Eastern Time on 
weekdays. See "Net Asset Value and Pricing of Orders" for more information. 
To confirm that each transaction instruction received by telephone is 
genuine, the Fund will record each telephone transaction, require the caller 
to provide the personal identification number (PIN) for the account and send 
you a written confirmation of each telephone transaction. Different 
procedures may apply to accounts that are registered to non-U.S. citizens or 
that are held in the name of an institution or in the name of an investment 
broker-dealer or other third-party. If reasonable procedures, such as those 
described above, are not followed, the Fund may be liable for any loss due to 
unauthorized or fraudulent instructions. 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. 

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

Retirement Plans 
You should contact the Retirement Plans Department of PSC at 1-800-622-0176 
for information on retirement plans for business, Simplified Employee Pension 
Plans, Individual Retirement Accounts (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 
Funds. The Account Application accompanying this Prospectus should not be 
used to establish any of these plans. Separate applications are required. 

Systematic Withdrawal Plans 
If the shares in your account have a total value of at least $10,000 you may 
establish a Systematic Withdrawal Plan with respect to the Fund providing for 
fixed payments at regular intervals. Periodic checks of $50 or more will be 
sent to you monthly or quarterly and your periodic redemptions of shares may 
be taxable to you. You may also direct that withdrawal checks be paid to 
another person, although if you make this designation after you have opened 
your account, a signature guarantee must accompany your instructions. 
Purchases of shares of the Fund at a time when you have a Systematic 
Withdrawal Plan in effect with respect to the Fund 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 Fund's Statement of Additional Information. 

Reinstatement Privilege 
If you redeem all or part of your shares of the Fund, you may reinvest all or 
part of the redemption proceeds without a sales commission in shares of the 
Fund if you send a written request to PSC not more than 90 days after your 
shares were redeemed. Your redemption proceeds will be reinvested at the next 
determined net asset value of the shares of the Fund after receipt of the 
written request for reinstatement. You may realize a gain or loss for federal 
income tax purposes as a result of the redemption, and special tax rules may 
apply. Subject to the provisions outlined under "Exchange Privilege" above, 
you may also reinvest in any other Pioneer mutual funds; in this case you 
must meet the minimum investment 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 filling out 
an Account Options Form, which you may request by calling 1-800-225-6292. 

VIII. INVESTMENT RESULTS 
The Fund may from time to time include yield information in advertisements or 
in information furnished generally to existing or proposed shareholders. 
Whenever yield information is provided, it includes a standardized yield 
calculation computed by dividing the Fund's net investment income per share 
during a base period of 30 days, or one month, by the maximum offering price 
per share of the Fund on the last day of such base period. (The Fund's net 
investment income per share is determined by dividing the Fund's net 
investment income during the base period by the average number of shares of 
the Fund entitled to receive dividends during the base period). The Fund's 
30-day yield is then "annualized" by a computation that assumes that the 
Fund's net investment income is earned and reinvested for a six-month period 
at the same rate as during the 30-day base period and that the resulting 
six-month income will be generated over an additional six months. 

<PAGE>
 
The Fund may also include in advertisements, and furnish to existing or 
prospective shareholders, information concerning the average annual total 
return on an investment in the Fund for a designated period of time. Whenever 
this information is provided, it includes a standardized calculation of 
average annual total return computed by determining the average annual 
compounded rate of return that would cause a hypothetical investment (after 
deduction of the maximum sales charge) made on the first day of the 
designated period (assuming all dividends and distributions are reinvested) 
to equal the resulting net asset value of such hypothetical investment on the 
last day of the designated period. The periods illustrated would normally 
include one, five and ten years. These standardized calculations do not 
reflect the impact of federal or state income taxes. 

The foregoing computation method is prescribed for advertising and other 
communications subject to SEC Rule 482. Communications not subject to this 
rule may contain one or more additional measures of investment results, 
computation methods and assumptions, including but not limited to: historical 
total returns; distribution returns; results of actual or hypothetical 
investments; changes in dividends, distributions or share values; or any 
graphic illustration of such data. These data may cover any period of the 
Fund's existence and may or may not include the impact of sales charges, 
taxes or other factors. 

Yield and average annual total return quotations of the Fund do not take into 
account any required payments for federal or state income taxes. 

The Fund's investment results will vary from time to time depending on market 
conditions, the composition of the Fund's portfolio and operating expenses of 
the Fund. Therefore, any prior investment results of the Fund should not be 
considered representative of what an investment in the Fund may earn in any 
future period. These factors and possible differences in the methods used in 
calculating investment results should be considered when comparing 
performance information regarding the Fund to information published for other 
investment companies, investment vehicles, and unmanaged indexes. Yield and 
return quotations should also be considered relative to the risks associated 
with the Fund's investment objective and policies. Yields may be affected by 
sinking fund call provisions and optional redemption features of portfolio 
securities which may have the effect of reducing the stated average maturity 
of the Fund's portfolio. At any time in the future, yields and return 
quotations may be higher or lower than past yields or return quotations and 
there can be no assurance that any historical yield or return quotation will 
continue in the future. 

The Fund may also include comparative performance information in advertising 
or marketing the Fund's shares. This performance information may include 
rankings or listing by magazines, newspapers, or independent statistical or 
ratings services, such as Lipper Analytical Services, Inc. and Ibbotson 
Associates. 

For more information about the calculation methods used to compute the Fund's 
investment results, see the Statement of Additional Information. 

IX. SHARES OF THE FUND 
The Fund, an open-end diversified investment management company, was 
established as a Nebraska corporation on January 19, 1968 and reorganized as 
a Delaware business trust on June 30, 1994. The Trustees are responsible for 
the overall management and supervision of its affairs. 

Each share represents an equal proportionate interest in the Fund with each 
other share. Shares entitle their holders to one vote per share in the 
election of Trustees and other matters submitted to shareholders. Shares have 
noncumulative voting rights, do not have preemptive or subscription rights 
and are transferable. The Trustees are empowered, without shareholder 
approval, by the Agreement and Declaration of Trust (the "Declaration of 
Trust") and By-Laws to create additional series of shares and to classify and 
reclassify any new or existing series of shares into one or more classes. 

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 assets of any other 
series or be liable for the expenses or liabilities of any other series. The 
Fund is authorized, but does not currently intend to, issue multiple classes 
of its 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 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. 

The Fund does not intend to hold annual shareholder meetings. Shareholders 
have certain rights, as set forth in the Declaration of Trust, including the 
right to call a meeting of shareholders for the purpose of voting on the 
removal of one or more Trustees. Such removal can be effected upon the action 
of two-thirds of the outstanding shares of the Fund.
