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 annual operating expenses based on actual 
expenses for Class A and Class B shares for the fiscal year ended December 
31, 1995. For Class C shares, operating expenses are based on estimated 
expenses that would have been incurred if Class C shares had been outstanding 
for the fiscal year ended December 31, 1995.

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

   (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 ("CDSC") as further 
       described under "How to Sell Fund Shares." 

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

   You would pay the following 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:

</TABLE>

 *Class B shares convert to Class A shares eight years after purchase; 
  therefore, Class A expenses are used after year eight. 
**Class C shares redeemed during the first year after purchase are subject to 
  a 1% CDSC. 

  The example above assumes the 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, Rule 12b-1 fees and other 
expenses of the Fund, including information regarding the basis upon which 
management fees and Rule 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 seek as high a level of income 
exempt from regular federal income tax as possible, consistent with 
preservation of capital. To achieve this objective, the Fund invests in a 
diversified portfolio of obligations issued by or on behalf of states, 
counties and municipalities of the United States ("U.S.") and their 
authorities and political subdivisions ("Tax-Exempt Bonds"), the interest on 
which is excluded from gross income for federal income tax purposes, in the 
opinion of counsel to the issuer of the bond. The Fund's portfolio will 
primarily consist of Tax-Exempt Bonds rated at the time of purchase within 
the three highest grades assigned by Moody's Investors Services, Inc. 
("Moody's") (Aaa, Aa or A) or Standard & Poor's Ratings Group ("S&P") (AAA, 
AA or A). Securities in which the Fund invests may not yield as high a level 
of current income on a pre-tax basis as securities subject to regular federal 
income tax or securities of lower quality which generally are less liquid and 
have greater market risk and price fluctuation. 
    

  The Fund may also invest in temporary investments consisting of: (1) notes 
issued by or on behalf of municipal issuers backed by the U.S. government; 
(2) notes of issuers having, at the time of purchase, an issue of outstanding 
Tax-Exempt Bonds rated within the three highest grades of the rating 
services as described above; (3) securities of other investment companies*; 
(4) obligations of the U.S. government, its agencies or instrumentalities*; 
(5) commercial paper rated in the highest grade by either of such rating 
services (Prime-I or A-I, respectively)*; (6) bank instruments (including 
certificates of deposit, time deposits and bankers' acceptances) of domestic 
or foreign banks with assets of $1 billion or more*; and (7) repurchase 
agreements on such securities* with banks or broker-dealers. During periods 
of normal market conditions, the Fund will have at least 80% of its net 
assets invested in Tax-Exempt Bonds, with up to 20% of the Fund's assets in 
temporary investments or cash. When the investment adviser believes that 
market conditions dictate a defensive posture, a greater percentage of the 
Fund's assets may be invested in temporary investments. The asterisk (*) 
indicates that the income from these securities is or may be subject to 
federal income tax. 

  The Fund may invest more than 25% of its total assets in securities, 
payments on which are derived from funds provided by companies in the gas, 
electric, telephone, sewer and water, public and private utility segments of 
the municipal bond market. The Fund will not purchase securities if, as a 
result of such transaction, more than 25% of its total assets would be 
invested in any one industry. For purposes of this limitation, Tax-Exempt 
Bonds, except those issued for the benefit of non-governmental users, are not 
considered to be part of an industry. The Fund may invest 25% or more of its 
total assets in Tax-Exempt Bonds of issuers in any one state and may invest 
25% or more of its total assets in industrial development bonds. 

Investment Company Securities 

   
  The Fund may invest up to 10% of the value of its total assets in securities 
of other investment companies, with up to 5% of the value of the Fund's total 
assets invested in securities of any one investment company, but may not own 
more than 3% of the outstanding voting securities of any one investment 
company. Because investments in other investment companies involve expenses 
being incurred by those companies as well as comparable expenses being 
incurred by the Fund, investments in other investment companies will 
generally be used only for short-term investing and only when the Fund 
reasonably anticipates that the net return to the Fund's shareholders will be 
advantageous, as compared to available alternatives, while maintaining the 
appropriate level of liquidity. It is expected that most of such investments 
will be in no-load, tax-free money market funds that invest, as far as 
practicable, in the same quality of investments as the Fund may invest in 
directly. 
    

Options 

  The Fund may write (sell) "covered" put and call options on fixed-income 
securities. Call options are "covered" by the Fund when it owns the 
underlying securities, or owns securities convertible into or carrying rights 
to acquire such securities without payment of additional consideration, which 
the option holder has the right to purchase, and put options are "covered" by 
the Fund when it has established a segregated account of cash or liquid, 
high-grade debt obligations sufficient to satisfy the Fund's obligation to 
purchase the underlying securities. The Fund receives a premium from writing 
a put or call option, which increases the Fund's gross income in the event 
the option expires unexercised or is closed out at a profit. By writing a 
call option, the Fund limits its opportunity to profit from any increase in 
the market value of the underlying security above the exercise price of the 
option. By writing a put option, the Fund assumes the risk that it may be 
required to purchase the underlying security for an exercise price higher 
than its then current market value, resulting in a capital loss unless the 
security subsequently appreciates in value. 

   
  The Fund intends to write and purchase options on securities primarily for 
hedging purposes and also in an effort to increase current income. 
Distributions to shareholders of any gains from options transactions will be 
taxable. Options on securities that are written or purchased by the Fund will 
be entered into on U.S. exchanges and in the over-the-counter market. 
Over-the-counter transactions involve certain risks which may not be present 
in a transaction on an exchange. The staff of the SEC has taken the position 
that over-the-counter options and assets used to cover over-the-counter 
options are illiquid and, therefore, together with other illiquid securities, 
cannot exceed 15% of the Fund's net assets. 
    

  The writing and purchase of options is a highly specialized activity which 
involves investment techniques and risks different from those associated with 
ordinary portfolio securities transactions. The successful use of options for 
hedging purposes depends in part on the investment adviser's ability to 
predict future price fluctuations and the degree of correlation between the 
options and securities markets. If the investment adviser is incorrect in its 
determination of the correlation between the securities or indices on which 
the options are written and purchased and the securities in the Fund's 
investment portfolio, the investment performance of the Fund will be less 
favorable than it would have been in the 

                                   4
<PAGE>
 
absence of such option transactions. The Fund pays brokerage commissions or 
spreads in connection with its options transactions. The writing of options 
could significantly increase the Fund's portfolio turnover rate. 

Futures Contracts and Options on Futures Contracts 

  To hedge against changes in interest rates and securities prices or for 
non-hedging purposes, the Fund may purchase and sell futures contracts on 
fixed income securities or indices composed of such securities, including 
municipal bonds and U.S. Treasury securities, and purchase and write call and 
put options on such futures contracts. The Fund may also enter into closing 
purchase and sale transactions with respect to any of such contracts and 
options. The futures contracts may be based on various securities (such as 
U.S. government securities), securities indices and other financial 
instruments and indices. The Fund will engage in futures and related options 
transactions only for bona fide hedging purposes as defined in regulations of 
the Commodities Futures Trading Commission or for non-hedging, speculative 
purposes to the extent permitted by such regulations. 

  The Fund may not purchase or sell futures contracts or purchase or sell 
related options for non-hedging purposes, except for closing purchase or sale 
transactions, if immediately thereafter the sum of the amount of initial 
margins and premiums on the Fund's outstanding non-hedging positions in 
futures and related options would exceed 5% of the market value of the Fund's 
net assets. Transactions in futures contracts and options on futures involve 
brokerage costs, require margin deposits and, in the case of contracts and 
options obligating it to purchase securities, require the Fund to segregate 
assets with a value equal to the amount of the Fund's obligations. The Fund 
will not enter into option transactions or futures contracts or options 
thereon if immediately thereafter more than 35% of the market value of the 
Fund's net assets would be represented by such instruments. 

  While transactions in futures contracts and options on futures may reduce 
certain risks, such transactions themselves entail certain other risks. Thus, 
while the Fund may benefit from the use of futures and options on futures, 
unanticipated changes in interest rates or securities prices may result in a 
poorer overall performance for the Fund than if it had not entered into any 
futures contracts or options transactions. The loss incurred by the Fund in 
writing options on futures is potentially unlimited and may exceed the amount 
of the premium received. In the event of an imperfect correlation between a 
futures position and a portfolio position which is intended to be protected, 
the desired protection may not be obtained and the Fund may be exposed to 
risk of loss. Perfect correlation between the Fund's futures positions and 
portfolio positions may be impossible to achieve. The Fund's transactions in 
options and futures contracts may be limited by the requirements of the 
Internal Revenue Code of 1986, as amended (the "Code"), for qualification as 
a regulated investment company, and distributions to shareholders of any 
gains from such transactions will be taxable. 

Other Information 

  The yields and market values of municipal securities are determined 
primarily by the general level of interest rates, the creditworthiness of the 
issuers of municipal securities and economic and political conditions 
affecting such issuers. Due to their tax exempt status, the yields and market 
prices of municipal securities may be adversely affected by changes in tax 
rates and policies, which may have less effect on the market for taxable 
fixed income securities. Moreover, certain types of municipal securities, 
such as housing revenue bonds, involve prepayment risks which could affect 
the yield on such securities. 

  Investments in municipal securities are subject to the risk that the issuer 
could default on its obligations. Such a default could result from the 
inadequacy of the sources or revenues from which interest and principal 
payments are to be made or the assets collateralizing such obligations. 
Revenue bonds, including private activity bonds, are backed only by specific 
assets or revenue sources and not by the full faith and credit of the 
governmental issuer. 

   
  The Fund will limit portfolio turnover to the extent practicable and 
consistent with its investment objective and policies. While it does not 
intend to engage in short-term trading, the Fund is not precluded from taking 
advantage of short-term trends and yield disparities that might occur from 
time to time. A higher portfolio turnover rate (over 100%) may result in 
correspondingly higher transaction costs and may increase the realization of 
net short-term capital gains, distributions of which are taxable to 
shareholders as ordinary income. See "Financial Highlights" for actual rates. 
    

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 
mar-
                                   5

<PAGE>
 
ket 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. 

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 fixed income portfolio managed by PMC, including the Fund, is 
overseen by the Domestic Fixed Income Portfolio Management Committee, which 
consists of PMC's most senior domestic fixed income 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. Fixed income investments at PMC, including those made on behalf of the 
Fund, are under the general supervision of Mr. Sherman Russ, a Senior Vice 
President of PMC. Mr. Russ joined PMC in 1983. Mr. Mark Winter, Vice 
President of the Fund and PMC, is primarily responsible for the day-to-day 
management of the Fund. Mr. Winter assumed responsibility for the Fund in 
March 1986 when it was managed by FMC. Mr. Winter joined PMC in 1993. In 
certain instances where the individual named above is unavailable, primary 
responsibility for the day-to-day management of the Fund may be assumed 
temporarily by Ms. Kathleen D. McClaskey who joined PMC in 1986 and is a Vice 
President of PMC. 

  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 
shares of the Fund. Prior to December 1, 1993, 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 

                                   6
<PAGE>
 
the SEC, state or blue sky securities agencies and foreign countries, 
including the preparation of Prospectuses and Statements of Additional 
Information for filing with regulatory agencies; (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: 

   
<TABLE>

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% 
</TABLE>

  For the fiscal year ended December 31, 1995, the Fund paid a management fee 
of $2,153,083 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 14% of the outstanding capital stock of PGI as of February 29, 
1996. 
    

V. FUND SHARE ALTERNATIVES 

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

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

  Class B Shares. If you plan to invest up to $250,000, Class B shares are 
available to you. Class B shares are sold without an initial sales charge, 
but are subject to a CDSC of up to 4% if redeemed within six years. Class B 
shares are subject to distribution and service fees at a combined annual rate 
of 1.00% 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. 

   
  Class C Shares. Class C shares are sold without an initial sales charge, but 
are subject to a 1% CDSC if they are redeemed within the first year after 
purchase. Class C shares are subject to distribution and service fees at a 
combined annual rate of up to 1.00% of the Fund's average daily net assets 
attributable to Class C shares. Your entire investment in Class C shares is 
available to work for you from the time you make your investment, but the 
higher distribution fee paid by Class C shares will cause your Class C shares 
to have a higher expense ratio and to pay lower dividends, to the extent 
dividends are paid, than Class A shares. Class C shares have no conversion 
feature. 

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

  Investment dealers or their representatives may receive different 
compensation depending on which Class of shares they sell. Shares may be 
exchanged only for shares of the same Class of another Pioneer mutual fund 
and shares acquired in the exchange will continue to be subject to any CDSC 
applicable to the shares of the Pioneer mutual 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. 
    


                                    7
<PAGE>
 
Securities are valued at the last sale price on the principal exchange or 
market where they are traded. Securities which have not traded on the date of 
valuation or securities for which sales prices are not generally reported are 
valued at the mean between the current bid and asked prices. All assets of 
the Fund for which there is no other readily available valuation method are 
valued at their fair value as determined in good faith by the Trustees. 

VII. HOW TO BUY FUND SHARES 

   
  You may buy Fund shares from any securities broker-dealer which has a sales 
agreement with PFD. If you do not have a securities broker-dealer, please 
call 1-800-225-6292. Shares will be purchased at the public offering price, 
that is, the net asset value per share plus any applicable sales charge, next 
computed after receipt of a purchase order, except as set forth below. 

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

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

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

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

  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 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 may pay 
to Mutual of Omaha Investor Services, Inc. 50% of PFD's retention of any 
sales commission on sales of the Fund's Class A shares through such dealer. 

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

                                   8
<PAGE>

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 the Fund may be sold at 
net asset value per share without a sales charge to 401(k) retirement plans 
with 100 or more participants or at least $500,000 in plan assets. 
Information about such arrangements is available from PFD. 

  Class A shares of the Fund may also be sold at net asset value per share 
without a sales charge to: (a) current or former Trustees and officers of the 
Fund and partners 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 be sold 
at net asset value without a sales charge to Optional Retirement Program (the 
"Program") participants if (i) the employer has authorized a limited number 
of investment company providers for the Program, (ii) all authorized 
investment company providers offer their shares to Program participants at 
net asset value, (iii) the employer has agreed in writing to actively promote 
the authorized investment providers to Program participants and (iv) the 
Program provides for a matching contribution for each participant 
contribution. 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 longest during the six-year period. As a result, you will pay the 
lowest possible CDSC.

Seventh and thereafter                       none 
</TABLE>

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

   
  Class B shares will automatically convert into Class A shares at the end of 
the calendar quarter that is eight years after the purchase date, except as 
noted below. Class B shares acquired by exchange from Class B shares of 
another Pioneer fund will convert into Class A shares based on the date of 
the initial purchase and the applicable CDSC. Class B shares acquired through 
reinvestment of distributions will convert into Class A shares based on the 
date of the initial purchase to which such shares relate. For this purpose, 
Class B shares acquired through reinvestment of distribu- 


                                   9
<PAGE>

tions 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 has obtained or an opinion of counsel that such 
conversions will not constitute taxable events for federal tax purposes. 
There can be no assurance that such ruling or opinion will be available at 
the time any particular conversion would normally occur. The conversion of 
Class B shares to Class A shares will not occur if such ruling 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. 
    
Class C Shares 

  You may buy Class C shares at net asset value per share without the 
imposition of an initial sales charge; however, Class C shares redeemed 
within one year of purchase will be subject to a CDSC of 1.00%. The charge 
will be assessed on the amount equal to the lesser of the current market 
value or the original purchase cost of the shares being redeemed. No CDSC 
will be imposed on increases in account value above the initial purchase 
price, including shares derived from the reinvestment of dividends or capital 
gains distributions. Class C shares do not convert to any other Class of Fund 
shares. 

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

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

  Waiver or Reduction of Contingent Deferred Sales Charge. The CDSC on Class B 
shares may be waived or reduced for non-retirement accounts if: (a) the 
redemption results from the death of all registered owners of an account (in 
the case of UGMAs, UTMAs and trust accounts, 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 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 C shares and on any Class A shares subject to a CDSC may 
be waived or reduced as follows: (a) for automatic redemptions as described 
in "Systematic Withdrawal Plans" (limited to 10% of the value of the 
account); (b) if the redemption results from the death or a total and 
permanent disability (as defined in Section 72 of the Code) occurring after 
the purchase of the shares being redeemed of a shareowner or participant in 
an employer-sponsored retirement plan; (c) if the distribution is part of a 
series of substantially equal payments made over the life expectancy of the 
participant or the joint life expectancy of the participant and his or her 
beneficiary; or (d) if the distribution is to a participant in an 
employer-sponsored retirement plan and is (i) a return of excess employee 
deferrals or contributions, (ii) a qualifying hardship distribution as 
defined by the Code, (iii) from a termination of employment, (iv) in the form 
of a loan to a participant in a plan which permits loans, or (v) from a 
qualified defined contribution plan and represents a participant's directed 
transfer (provided that this privilege has been pre-authorized through a 
prior agreement with PFD regarding participant directed transfers). 

  The CDSC on Class B and Class C 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 connec-


                                    10
<PAGE>
 
tion 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. 

   
  Broker-Dealers. An order for any Class of Fund shares received by PFD from a 
broker-dealer prior to the close of regular trading on the Exchange is 
confirmed at the price appropriate for that Class as determined at the close 
of regular trading on the Exchange on the day the order is received, provided 
the order is received 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 not binding on, and may be rejected by, PFD until it has 
been confirmed in writing by PFD and payment has been received. 

VIII. HOW TO SELL FUND SHARES 

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

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

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

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

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

  In Writing. You may 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: 

  (bullet) you wish to sell over $50,000 worth of shares, 

  (bullet) your account registration or address has changed within the last 30 
           days, 

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

  (bullet) the check is not being made out to the account owners, or 

  (bullet) the sale proceeds are being transferred to a Pioneer account with a 
           different registration. 

   
  Your request should include your name, the Fund's name, your fund account 
number, the Class of shares to be redeemed, the dollar amount or number of 
shares to be redeemed, and any other applicable requirements as described 
below. Unless instructed otherwise, PSC will send the proceeds of the sale to 
the address of record. Fiduciaries 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 PSC. You may redeem up to $50,000 per day of 
your shares by telephone or fax and receive the proceeds by check or bank 
wire or electronic funds transfer. The redemption proceeds must be made 
payable exactly as the account is registered. To receive the proceeds by 
check: 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 


                                   11
<PAGE>
 
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 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 FactFone(SM), will be recorded. You are strongly urged to consult with 
your financial representative prior to requesting a telephone exchange. See 
"Telephone Transactions and Related Liabilities" below. 

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

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

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

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

X. DISTRIBUTION PLANS 

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

  Pursuant to the Class A Plan, the Fund reimburses PFD for its actual 
expenditures to finance any activity primarily intended to result in the sale 
of Class A shares or to provide services to holders of Class A shares, 
provided the catego-
                                   12
<PAGE>
 
ries of expenses for which reimbursement is made are approved by the Fund's 
Board of Trustees. As of the date of this Prospectus, the Board of Trustees 
has approved the following categories of expenses for Class A shares of the 
Fund: (i) a service fee to be paid to qualified broker-dealers in an amount 
not to exceed 0.25% per annum of the Fund's daily net assets attributable to 
Class A shares; (ii) reimbursement to PFD for its expenditures for 
broker-dealer commissions and employee compensation on certain sales of the 
Fund's Class A shares with no initial sales charge (See "How to Buy Fund 
Shares"); and (iii) reimbursement to PFD for expenses incurred in providing 
services to Class A shareholders and supporting broker-dealers and other 
organizations (such as banks and trust companies) in their efforts to provide 
such services. Banks are currently prohibited under the Glass-Steagall Act 
from providing certain underwriting or distribution services. If a bank was 
prohibited from acting in any capacity or providing any of the described 
services, management would consider what action, if any, would be 
appropriate. 

  Expenditures of the Fund pursuant to the Class A Plan are accrued daily and 
may not exceed 0.25% of the Fund's average daily net assets attributable to 
Class A shares. Distribution expenses of PFD are expected to substantially 
exceed the distribution fees paid by the Fund in a given year. The Class A 
Plan may not be amended to increase materially the annual percentage 
limitation of average net assets which may be spent for the services 
described therein without approval of the shareholders of the Fund. 

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

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

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

  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 or the Class C Plan for which 
there is no dealer of record or for which qualification standards have not 
been met as partial consideration for personal services and/or account 
maintenance services performed by PFD or its affiliates for shareholder 
accounts. 
    

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. The Code permits tax-exempt 
interest received by the Fund to flow through as tax-exempt "exempt-interest 
dividends" to the Fund's shareholders, provided that the Fund qualifies as a 
regulated investment company and at least 50% of the value of the total 
assets of the Fund at the close of each quarter of its taxable year consists 
of tax-exempt obligations. However, distributions derived from interest on 
certain "private activity bonds" will be subject to the federal alternative 
minimum tax for individuals, estates or trusts that are subject to such tax, 
and all tax exempt distributions may result in or increase a corporate 
shareholder's liability for the federal corporate alternative minimum tax. 
    

  Interest on indebtedness incurred by a shareholder to purchase or carry 
shares of the Fund will not be deductible for federal income tax purposes to 
the extent it is deemed related to exempt-interest dividends. The Fund may 
not be an appropriate investment for persons who are "substantial users" of 
facilities financed by industrial revenue or private activity bonds or 
persons related to substantial users. Shareholders receiving social security 
or certain railroad retirement benefits may be subject to federal income tax 
on a portion of such benefits as a result of receiving investment income, 
including exempt-interest dividends and other distributions paid by the Fund. 

  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 with 
respect to each calendar year. The Fund intends to make distributions in a 
timely manner and accordingly does not expect to be subject to the excise 
tax. 

   
  Each business day the Fund declares a dividend consisting of substantially 
all of the Fund's net investment income. Shareholders begin earning dividends 
on the first business day following receipt of payment for purchased shares. 
Shares continue to earn dividends up to and including the 


                                   13
<PAGE>
 
date of redemption. Dividends are normally paid on the last business day of 
the month or shortly thereafter. The Fund's net investment income consists of 
the interest income it earns, less expenses. In computing interest income, 
the Fund amortizes premium or accrues discount on long-term debt securities 
only to the extent required for federal income tax purposes. The Fund will 
make distributions from net long term capital gains, if any, in December. 
Distributions from net short-term capital gains, if any, may be paid with 
such dividends, and other distributions from income and/or capital gains may 
also be made at such other times as may be necessary to avoid federal income 
or excise tax. 
    

  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. 

  The Fund's dividends from its taxable net investment income, including 
taxable interest income, taxable original issue discount, market discount 
income, income from securities lending 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. 

  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 payees may be subject to 31% backup 
withholding of federal income tax if the Fund is not provided with the 
shareholder's correct taxpayer identification number and certification that 
the number is correct and that the shareholder is not subject to such backup 
withholding or if the Fund receives notice from the IRS or a broker that 
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. A state income (and possibly local income and/or 
intangible property) tax exemption is generally available to the extent the 
Fund's distributions are derived from interest on (or, in the case of 
intangibles taxes, the value of its assets is attributable to) certain U.S. 
Government obligations and/or tax-exempt municipal obligations issued by or 
on behalf of the particular state or a political subdivision thereof, 
provided in some states that certain thresholds for holdings of such 
obligations an/or reporting requirements are satisfied. Non-U.S. shareholders 
and tax-exempt shareholders are subject to different tax treatment that is 
not described above. You should consult your own tax adviser regarding this 
possibility and other tax consequences under state, local and other 
applicable tax laws. 

XII. SHAREHOLDER SERVICES 

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

Account and Confirmation Statements 

  PSC maintains an account for each shareholder and all transactions of the 
shareholder are recorded in this account. Confirmation statements showing 
details of transactions are sent to shareholders as transactions occur, 
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 and Class C shares) to PSC (account number and 
Class of shares should be clearly indicated). The bottom portion of a 
confirmation statement may be used as a remittance slip to make additional 
investments. Additions to your account, whether by check or through a Pioneer 
Investomatic Plan, are invested in full and fractional shares of the Fund at 
the applicable offering price in effect as of the close of 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. 
                                    14

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 mutual 
fund account invested in a second Pioneer mutual fund account. The value of 
this second account must be at least $1,000 ($500 for Pioneer Fund or Pioneer 
II). Invested dividends may be in any amount, 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 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 9:00 p.m. Eastern time on weekdays. 
Computer-assisted transactions are available to shareholders who have 
pre-recorded certain bank information (see "FactFone(SM)"). You are strongly 
urged to consult with your financial representative prior to requesting any 
telephone transaction. To confirm that each transaction instruction received 
by telephone is genuine, the Fund will record each telephone transaction, 
require the caller to provide the personal identification number ("PIN") for 
the account and send you a written confirmation of each telephone 
transaction. Different procedures may apply to accounts that are registered 
to non-U.S. citizens or that are held in the name of an institution or in the 
name of an investment broker-dealer or other third-party. If reasonable 
procedures, such as those described above, are not followed, the Fund may be 
liable for any loss due to unauthorized or fraudulent instructions. The Fund 
may implement other procedures from time to time. In all other cases, neither 
the Fund, PSC or PFD will be responsible for the authenticity of instructions 
received by telephone, therefore, you bear the risk of loss for unauthorized 
or fraudulent telephone transactions. 
    

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

FactFone(SM)

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

Telecommunications Device for the Deaf (TDD) 

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

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 will be limited to 10% of the value of the account at 
the time the SWP is implemented. See "Waiver or Reduction of Contingent 
Deferred Sales Charge" for more information. Periodic payments of $50 or more 
will be sent to you, or any person designated by you, monthly or quarterly, 
and your periodic redemptions of shares may be taxable to you. Payments can 
be made either by check or electronic transfer to a bank account designated 
by you. If you direct that withdrawal checks be paid to another person after 
you have opened your account, a signature guarantee must accompany your 
instructions. Purchases of Class A shares of the Fund at a time when you have 
a SWP in effect 
                                   15
<PAGE>
 
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 19, 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 three classes of shares, designated as Class A, 
Class B and Class C. The shares of each class represent an interest in the 
same portfolio of investments of the Fund. Each class has equal rights as to 
voting, redemption, dividends and liquidation, except that each class bears 
different distribution and transfer agent fees and may bear other expenses 
properly attributable to the particular class. Class A, Class B and Class C 
shareholders have exclusive voting rights with respect to the Rule 12b-1 
distribution plans adopted by holders of those shares in connection with the 
distribution of shares. 
    

  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 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 Fund may from time to time include yield information for each Class of 
Fund shares 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 for each class of Fund shares during a base 
period of 30 days, or one month, by the maximum offering price per share for 
each class of Fund shares on the last day of such base period. (The Fund's 
net investment income per share for each Class is determined by dividing the 
Fund's net investment income for each Class during the base period by the 
Class's average number of shares entitled to receive dividends during the 
base period). The Class's 30-day yield is then "annualized" by a computation 
that assumes that the Class'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. 

  The Fund may also from time to time advertise its taxable equivalent yield 
for each Class of Fund Shares. The Class's taxable equivalent yield is 
determined by dividing that portion of the Class's yield (calculated as 
described above) that is tax exempt by one minus the stated federal income 
tax rate and adding the product to that portion, if any, of the Class's yield 
that is not tax exempt. For a table of sample taxable equivalent yields, 
please see the Appendix. 

   
  The average annual total return (for a designated period of time) on an 
investment in the Fund may also be included in 


                                   16
<PAGE>
 
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 4.50%; for Class B and Class C shares the calculation reflects the 
deduction of any applicable CDSC. The periods illustrated would normally 
include one, five and ten years (or since the commencement of the public 
offering of the shares of a Class, if shorter) through the most recent 
calendar quarter. 
    

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

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

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

XV. APPENDIX: 
Taxable Equivalent Yields* 

  The tables below show the approximate taxable yields which are equivalent to 
hypothetical tax-exempt yields from 5% to 9% under Federal income tax laws 
applicable to individuals during 1996.

 * Net amount subject to Federal income tax after deductions and exemptions. 
   Table does not reflect the effect of Deduction Limitation and Exemption 
   Phaseout described below** or of the alternative minimum tax, if any. 
   Table assumes person filing Single Return is not a married individual 
   filing a separate return, a surviving spouse, or a head of household. 
** Deduction Limitation: Each $100 of adjusted gross income ("AGI") in excess 
   of $117,950 ($58,975 for marrieds filing separately) causes the loss of $3 
   of itemized deductions. This limitation affects all itemized deductions 
   other than medical expenses, investment interest, and casualty, theft and 
   wagering losses. However, not more than 80% of a taxpayer's itemized 
   deductions can be eliminated.The threshold amounts will be adjusted for 
   inflation from year to year. 
   Exemption Phaseout: Each $2,500 or fraction thereof of AGI in excess of 
   $176,950 for joint filers ($117,950 for single taxpayers) causes taxpayers 
   to lose 2% of their personal exemptions. The threshold amounts will be 
   adjusted for inflation from year to year. 

The following formula can be used to calculate a taxable yield which is 
equivalent to the corresponding tax-free yield: 

            Tax Free Yield 
         ---------------------      =    Taxable Equivalent Yield 
         1 - Your Tax Bracket 

For example, if you are in the 28% tax bracket and earn a tax-free yield of 
7%, the taxable equivalent yield would be 9.72%. 

                   7%           .07     
                -------   =     ---     = 9.72%
                1 - 28%         .72 

There can be no assurance that the Fund will achieve any specific tax-exempt 
yield. While it is expected that a substantial portion of the interest income 
distributed to investors in the Fund will be exempt from regular federal 
income taxes, portions of such distributions may be subject to regular 
federal income tax orfederal alternative minimum tax. In addition, all or a 
substantial portion of such distributions may be subject to state and local 
taxes. Subsequent tax law changes could result in prospective or retroactive 
changes in the tax brackets, tax rates and tax equivalent yields set forth 
above.

  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.

   
         The  investment  objective  of the  Fund is to seek as high a level  of
income exempt from federal income tax as possible,  consistent with preservation
of  capital.  To  achieve  this  objective,  the Fund  intends  to  invest  in a
diversified portfolio of obligations issued by or on behalf of states,  counties
and  municipalities  of the United  States  ("U.S.") and their  authorities  and
political  subdivisions  ("Tax-Exempt Bonds"), the interest on which is excluded
from gross income for federal income tax purposes. All of the Fund's assets will
consist of: (1) Tax-Exempt  Bonds which are rated at the time of purchase within
the three highest grades assigned by Moody's Investors Service, Inc. ("Moody's")
(Aaa, Aa or A) or Standard & Poor's  Ratings  Group  ("S&P")  (AAA,  AA, A); (2)
temporary  investments  as  described  in the  Prospectus;  and (3) cash.  While
ratings at the time of purchase will determine which securities may be acquired,
a  subsequent  reduction  in rating  will not require the Fund to dispose of the
securities.  Investment in  lower-quality  securities  may provide higher yields
than  higher-rated  securities;  however,  the added risk of  investing in lower
quality  securities  might not be consistent with  preservation of capital.  The
ratings of Moody's  and S&P  represent  their  opinions as to the quality of the
Tax-Exempt Bonds which they undertake to rate. It should be emphasized, however,
that   ratings  are  general  and  are  not   absolute   standards  of  quality.
Consequently,  Tax-Exempt  Bonds with the same  maturity,  coupon and rating may
have different yields while Bonds of the same maturity and coupon with different
ratings may have the same yield.  There is no assurance the Fund will attain its
investment  objective.  For a description of the ratings of commercial paper and
the other debt securities permitted as temporary investments, see Appendix A.
    

  Municipal Lease Obligations

   
         Municipal   lease   obligations   or  installment   purchase   contract
obligations   (collectively,   "lease   obligations")  have  special  risks  not
ordinarily  associated  with  other  Tax-Exempt  Bonds  (as  set  forth  in  the
Prospectus). Although lease obligations do not constitute general obligations of
the municipality for which the  municipality's  taxing power is pledged, a lease
obligation  ordinarily is backed by the  municipality's  covenant to budget for,
appropriate  and make the  payments  due under the lease  obligations.  However,
certain lease obligations contain "non-appropriation" clauses which provide that
the  municipality  has no  obligation  to make  lease  or  installment  purchase
payments in future  years  unless  money is  appropriated  for such purpose on a
yearly basis.  In addition to the  "non-appropriation"  risk,  these  securities
represent a relatively  new type of  financing  that has not yet  developed  the
depth  of  marketability  associated  with  more  conventional  bonds.  Although
"non-appropriation"  lease  obligations  are  secured  by the  leased  property,
disposition of the property in the event of foreclosure  might prove  difficult.
The Fund will seek to minimize these risks.
    

                                      -2-
<PAGE>

         In determining the liquidity of municipal lease obligations, the Fund's
officers,  under  guidelines  established by the Fund's Board of Trustees,  will
consider:  (1)  the  essential  nature  of the  leased  property;  and  (2)  the
likelihood that the municipality will discontinue  appropriating funding for the
leased  property  because the  property  is no longer  deemed  essential  to the
operation of the municipality.

         If leased  property is  determined  not to be essential in nature or if
there is a  likelihood  that the  municipality  will  discontinue  appropriating
funding,  then the  following  factors will also be  considered  in  determining
liquidity:

         (1) any relevant  factors  related to the general credit quality of the
municipality, which may include: (a) whether the lease can be canceled; (b) what
assurance there is that the assets represented by the lease can be sold; (c) the
strength  of the  lessee's  general  credit  (e.g.,  its  debt,  administrative,
economic and financial characteristics); and (d) the legal recourse in the event
of failure to appropriate.

         (2) any relevant factors related to the  marketability of the municipal
lease obligation  which may include:  (a) the frequency of trades and quotes for
the  obligation;  (b) the number of  dealers  willing  to  purchase  or sell the
obligation and the number of other potential purchasers;  (c) the willingness of
dealers to undertake to make a market in the  obligation;  and (d) the nature of
the marketplace trades,  including the time needed to dispose of the obligation,
the method of soliciting offers, and the mechanics of transfer.

   
  Zero Coupon and Deferred Interest Bonds
    

         Tax-Exempt  Bonds in which the Fund may invest also include zero coupon
bonds and deferred interest bonds. Zero coupon bonds and deferred interest bonds
are debt obligations which are issued at a significant discount from face value.
While zero  coupon  bonds do not  require  the  periodic  payment  of  interest,
deferred interest bonds provide for a period of delay before the regular payment
of interest begins.  The discount  approximates the total amount of interest the
bonds will  accrue and  compound  over the period  until  maturity  or the first
interest  payment date at a rate of interest  reflecting  the market rate of the
security at the time of issuance.  Zero coupon bonds and deferred interest bonds
benefit the issuer by  mitigating  its need for cash to meet debt  service,  but
also  require a higher  rate of return to attract  investors  who are willing to
defer receipt of such cash. Such investments may experience  greater  volatility
in value than debt obligations which make regular payments of interest. The Fund
will accrue income on such investments for tax and accounting purposes, which is
distributable to shareholders. Since no cash is received at the time of accrual,
the Fund may be required to liquidate other portfolio  securities to satisfy its
distribution obligations.

  Residual Interests in Municipal Securities

         Certain municipal  securities are divided into short-term and long-term
components. The short-term component has a long-term maturity, but pays interest
at a short-term rate that is reset by means of a "dutch auction" or


                                      -3-
<PAGE>

similar  method  at  specified  intervals  (typically  35 days).  The  long-term
component or "residual  interest"  pays interest at a rate that is determined by
subtracting  the interest paid on the short-term  component from the coupon rate
on the municipal securities themselves.  Consequently, the interest rate paid on
residual  interests will increase when short-term  interest rates are declining,
and will decrease when short-term  interest rates are increasing.  This interest
rate adjustment  formula results in the market value of residual interests being
significantly  more volatile than that of ordinary  municipal  securities.  In a
declining  interest rate  environment,  residual  interests can provide the Fund
with a means of increasing or maintaining the level of tax-exempt  interest paid
to  shareholders.  However,  because of the market  volatility  associated  with
residual  interests,  the Fund will not invest more than 10% of its total assets
in residual interests in municipal securities.

  Options

         The  Fund  can  write  (sell)   "covered"   put  and  call  options  on
fixed-income  securities.  Call options  written by the Fund give the holder the
right to buy the underlying  securities  from the Fund at a fixed exercise price
up to a stated expiration date or, in the case of certain options, on such date.
Put options written by the Fund give the holder the right to sell the securities
to the Fund  during  the term of the  option at a fixed  exercise  price up to a
stated  expiration date or, in the case of certain  options,  on such date. Call
options are  "covered"  by the Fund,  for example,  when it owns the  underlying
securities  which the option  holder has the right to purchase,  and put options
are  "covered" by the Fund,  for example,  when it has  established a segregated
account of cash or short-term money market  instruments  which can be liquidated
promptly  to satisfy  any  obligation  of the Fund to  purchase  the  underlying
securities.  The Fund will  receive a premium from writing a put or call option,
which  increases  the  Fund's  gross  income  in the event  the  option  expires
unexercised or is closed out at a profit.

         By writing a call  option,  the Fund limits its  opportunity  to profit
from any  increase  in the market  value of the  underlying  security  above the
exercise price of the option. By writing a put option, the Fund assumes the risk
that it may be required  to purchase  the  underlying  security  for an exercise
price  higher  than its then  current  market  value,  resulting  in a potential
capital loss unless the security subsequently appreciates in value.

         The Fund could  terminate  an option that it has  written  prior to its
expiration  by  entering  into a  "closing  purchase  transaction"  in  which it
purchases an option having the same terms as the option written. It is possible,
however, that illiquidity in the options markets may make it difficult from time
to time for the Fund to close out its written option  positions.  The Fund could
also purchase put or call options in  anticipation  of changes in interest rates
which  may  adversely  affect  the  value  of its  portfolio  or the  prices  of
securities that the Fund wants to purchase at a later date. The premium paid for
a put or call option plus any transaction costs will reduce the benefit, if any,
realized by the Fund upon exercise of the option,  and,  unless the price of the
underlying security changes sufficiently, the option may expire without value to
the Fund.

                                      -4-
<PAGE>

   
         The Fund intends to write and purchase options on securities  primarily
for hedging purposes and also in an effort to increase  current income.  Options
on securities  that are written or purchased by the Fund will be entered into on
U.S.  securities  exchanges  regulated by the Securities and Exchange Commission
("SEC")  and  in  the  over-the-counter  market.  Over-the-counter  transactions
involve certain risks which may not be present in an exchange  environment.  The
staff of the SEC has taken the position that purchased  over-the-counter options
and assets used to cover  written  over-the-counter  options are  illiquid  and,
therefore,  together  with other  illiquid  securities,  cannot  exceed 15% of a
Fund's net assets.
    

  Futures Contracts and Options on Futures Contracts

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

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

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

         Positions  taken  in the  futures  markets  are  not  normally  held to
maturity but are instead liquidated  through  offsetting  transactions which may
result  in a  profit  or a loss.  A  clearing  corporation  associated  with the
exchange on which futures on  securities  are traded  guarantees  that, if still
open, the sale or purchase will be performed on the settlement date.

         Hedging  Strategies.  Hedging,  by use of futures  contracts,  seeks to
establish  with  more  certainty  the  effective  price  and rate of  return  on
portfolio  securities and securities  that the Fund owns or proposes to acquire.
The Fund may,  for  example,  take a "short"  position in the futures  market by
selling  futures  contracts  in order to hedge  against an  anticipated  rise in
interest  rates that would  adversely  affect the value of the Fund's  portfolio
securities. Such futures contracts may include contracts for the future 


                                      -5-
<PAGE>

delivery  of  securities  held by the Fund or  securities  with  characteristics
similar to those of the Fund's portfolio  securities.  If, in the opinion of the
Fund's investment  adviser,  there is a sufficient degree of correlation between
price trends for the Fund's portfolio  securities and futures contracts based on
other financial  instruments,  securities indices or other indices, the Fund may
also enter into such futures contracts as part of its hedging strategy. Although
under some  circumstances  prices of securities  in the Fund's  portfolio may be
more or  less  volatile  than  prices  of such  futures  contracts,  the  Fund's
investment  adviser  will  attempt to  estimate  the  extent of this  volatility
difference based on historical patterns and compensate for any such differential
by having the Fund enter into a greater or lesser number of futures contracts or
by attempting  to achieve only a partial  hedge against price changes  affecting
the Fund's securities  portfolio.  When hedging of this character is successful,
any  depreciation  in the value of portfolio  securities  will be  substantially
offset by appreciation in the value of the futures position.  On the other hand,
any unanticipated  appreciation in the value of the Fund's portfolio  securities
would be substantially offset by a decline in the value of the futures position.

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

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

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

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

                                      -6-
<PAGE>

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

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

         As an  alternative  to literal  compliance  with the bona fide  hedging
definition,  a CFTC  regulation  permits  the  Fund to elect  to  comply  with a
different test, under which the sum of the amounts of initial margin deposits on
the  Fund's  existing  non-hedging  futures  contracts  and  premiums  paid  for
non-hedging  options on futures  (net of the  amount the  positions  are "in the
money") would not exceed 5% of the market value of the Fund's total assets.  The
Fund will engage in  transactions  in futures  contracts and options only to the
extent such  transactions  are consistent with the  requirements of the Internal
Revenue Code of 1986, as amended (the "Code"), for maintaining its qualification
as a regulated investment company for federal income tax purposes.

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

         While  transactions  in futures  contracts  and  options on futures may
reduce certain risks, such  transactions  themselves entail certain other risks.
Thus, while the Fund may benefit from the use of futures and options on futures,
unanticipated  changes in interest  rates or  securities  prices may result in a
poorer  overall  performance  for the Fund than if it had not  entered  into any
futures  contracts  or  options  transactions.  In  the  event  of an  imperfect


                                      -7-
<PAGE>

correlation  between  a  futures  position  and a  portfolio  position  which is
intended to be  protected,  the desired  protection  may not be obtained and the
Fund may be exposed to risk of loss.  The only  futures  contracts  available to
hedge the Fund's  portfolio are various futures on U.S.  Government  securities,
futures on a municipal securities index and stock index futures.

  Tax-Exempt Bonds

         Tax-Exempt  Bonds include debt  obligations  issued to obtain funds for
various public  purposes,  including the  construction of a wide range of public
facilities  such  as  airports,  bridges,  highways,  housing,  hospitals,  mass
transportation,  schools,  streets,  and  water and sewer  works.  Other  public
purposes  for which  Tax-Exempt  Bonds may be issued  include the  refunding  of
outstanding obligations, obtaining funds for general operating expenses, and the
obtaining  of funds to loan to other  public  institutions  and  facilities.  In
addition,  certain types of industrial development bonds are, or have been under
prior  law,  issued by or on behalf of  public  authorities  to obtain  funds to
provide privately-operated housing facilities, sports facilities,  convention or
trade show facilities,  airports, mass transit, port or parking facilities,  air
or water pollution  control  facilities,  and certain local facilities for water
supply, gas,  electricity,  or sewage or solid waste disposal.  Such obligations
are  included  within the term  Tax-Exempt  Bonds if the  interest  paid thereon
qualifies as excluded from gross income for federal  income tax purposes.  Other
types of industrial  development  bonds,  the proceeds of which are used for the
construction,  equipment, repair or improvement of privately operated industrial
or commercial facilities,  may constitute Tax-Exempt Bonds, although the current
federal tax laws place substantial limitations on the size of such issues.

         The two  principal  classifications  of  Tax-Exempt  Bonds are "general
obligation" and "revenue"  bonds.  General  obligation  bonds are secured by the
issuer's  pledge of its  faith,  credit  and  taxing  power for the  payment  of
principal and interest. Revenue bonds are payable only from the revenues derived
from a particular  facility or class of facilities  or, in some cases,  from the
proceeds  of a  special  excise or other  specific  revenue  source.  Industrial
development bonds which are Tax-Exempt Bonds are in most cases revenue bonds and
do not  generally  constitute  the  pledge of the  credit of the  issuer of such
bonds.  There are, of course,  variations in security of Tax-Exempt  Bonds, both
within a particular  classification  and between  classifications,  depending on
numerous factors.

         The Fund may invest more than 25% of its total assets in  securities of
companies in the gas, electric,  telephone,  sewer and water, public and private
utility segments of the municipal bond market. In view of this, an investment in
the Fund should be made with an  understanding of the  characteristics  of these
industries and the potential risks of such an investment. Industry-wide problems
include the effects of  fluctuating  economic  conditions,  energy  conservation
practices on levels of usage, difficulties in obtaining timely and adequate rate
relief,   compliance  with   environmental   regulations,   increasing   capital
expenditures and  uncertainties  with respect to fuel availability at reasonable
prices.  The Fund  will not  purchase  securities  if more than 25% of its total
assets would be invested in any one industry.  For purposes of this


                                      -8-
<PAGE>

limitation,   Tax-Exempt   Bonds,   except  those  issued  for  the  benefit  of
non-governmental  users, are not considered to be part of an industry.  The Fund
may invest 25% or more of its total assets in Tax-Exempt Bonds of issuers in any
one  state  or it may  invest  25% or more of its  total  assets  in  industrial
development bonds.

         The yields on  Tax-Exempt  Bonds are dependent on a variety of factors,
including general money market conditions,  general conditions of the Tax-Exempt
Bond market, the size of a particular offering,  the maturity of the obligation,
and the rating of the issue. The value of outstanding Tax-Exempt Bonds will vary
as a result of changing  evaluations of the ability of their issuers to meet the
interest  and  principal  payments.  Such values will also change in response to
changes in the interest rates payable on new issues of Tax-Exempt Bonds;  should
such interest rates rise, the values of outstanding bonds,  including those held
in the Fund's  portfolio,  will decline and (if  purchased at principal  amount)
would sell at a  discount,  and,  if such  interest  rates  fall,  the values of
outstanding  bonds will  increase and (if  purchased at principal  amount) would
sell at a  premium.  Changes  in the value of the  Tax-Exempt  Bonds held in the
Fund's  portfolio  arising from these or other factors will cause changes in the
net asset value per share of the Fund.

         From time to time,  proposals have been introduced  before Congress for
the purpose of restricting  or eliminating  the federal income tax exemption for
interest on Tax-Exempt  Bonds. It can be expected that similar  proposals may be
introduced in the future.  If such a proposal were enacted,  the availability of
Tax-Exempt  Bonds  for  investment  by the  Fund  and the  value  of the  Fund's
portfolio  would be  affected.  Additionally,  the  Fund  would  reevaluate  its
investment  objective and policies and consider  changes in the structure of the
Fund.

   
         The Fund will limit  portfolio  turnover to the extent  practicable and
consistent with its investment objective and policies.  While it does not intend
to engage in short-term  trading,  the Fund will not preclude itself from taking
advantage of short-term  trends and yield disparities that might occur from time
to time,  but not to the extent that such trading  would  jeopardize  the Fund's
qualification as a regulated  investment company under Subchapter M of the Code.
A  higher  portfolio  turnover  rate  will  result  in  correspondingly   higher
transaction costs.
    

  2.       INVESTMENT RESTRICTIONS

         The  Fund  considers  the   investment   objective  and  the  following
restrictions as fundamental policies which cannot be changed without approval by
a  "majority"  of the  Fund's  outstanding  voting  securities  (as such vote is
defined in Section 2(a)(42) of 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.

                                      -9-
<PAGE>

  The Fund may not:

1.       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,  more than 5% of the value of the  Fund's  total
         assets would then be invested in securities of any single  issuer.  For
         the  purpose of this  limitation,  the Fund will  regard each state and
         each political subdivision, agency or instrumentality of such state and
         each  multi-state  agency of which such state is a member as a separate
         issuer;

2.       Borrow money,  except from a bank for  temporary or emergency  purposes
         and not for  investment  purposes,  and  then  only  in an  amount  not
         exceeding  5% of the value of the  Fund's  total  assets at the time of
         borrowing;

3.       Pledge,  mortgage or  hypothecate  its assets,  except that,  to secure
         borrowings   permitted  by  subparagraph   (2)  above,  it  may  pledge
         securities having a market value at the time of pledge not exceeding 5%
         of the value of the Fund's total assets;

4.       Knowingly  purchase  or  otherwise  acquire  any  securities  which are
         subject to legal or contractual restrictions on resale or which are not
         readily marketable,  or purchase the securities of any other investment
         company,  except that it may make purchases of securities of investment
         companies in accordance with its investment  objective,  policies,  and
         restrictions  or as part of a merger,  consolidation  or acquisition of
         assets;

5.       Underwrite  any  issue of  securities,  except in  connection  with the
         purchase of  securities in accordance  with its  investment  objective,
         policies   and   limitations,    or   participate   on   a   joint   or
         joint-and-several basis in any securities trading account;

6.       Purchase or sell real estate (or real estate limited partnerships), but
         this shall not prevent the Fund from  investing in Tax-Exempt  Bonds or
         other  permitted  obligations  secured  by  real  estate  or  interests
         therein;

7.       Purchase or sell  commodities or commodity  contracts  except  options,
         financial   futures  or  options  on  financial  futures  contracts  in
         accordance with its investment objective,  policies,  and restrictions,
         or  invest  in  oil,  gas  or  other  mineral  leases,  exploration  or
         development  programs,  or write or purchase  puts,  calls,  straddles,
         spreads or any combination thereof;

8.       Make loans,  except  through  the  purchase  of  securities,  including
         repurchase  agreements,  in accordance  with its investment  objective,
         policies and limitations;

9.       Make short sales of  securities  or purchase any  securities on margin,
         except for such  short-term  credits as are necessary for the clearance
         of  transactions  and  margin  payments  in  connection  with  options,
         financial futures contracts and options on financial futures contracts;
         or

                                      -10-
<PAGE>

   
10.      Purchase  or  retain  the  securities  of any  issuer  other  than  the
         securities of the Fund, if, to the Fund's knowledge, those officers and
         trustees of the Fund, or of the investment adviser or underwriter,  who
         own individually or beneficially more than 1/2 of 1% of the outstanding
         securities  of such issuer  together own  beneficially  more than 5% of
         such outstanding securities.
    

         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.

*    This fund is a closed-end fund.

**   This  is  a  series  of  eight  separate  portfolios  designed  to  provide
     investment  vehicles for the variable  annuity and variable life  insurance
     contracts of various  insurance  companies or for certain qualified pension
     plans.




         As of March 31,  1996,  to the  knowledge  of the Fund,  no  officer or
Trustee of the Fund owned 5% or more of the  issued  and  outstanding  shares of
PGI,  except Mr. Cogan who then owned  approximately  14% of such shares.  As of
March 31, 1996,  the officers and Trustees held in aggregate less than 1% of the
outstanding  shares of the Fund.  As of March 31, 1996,  to the knowledge of the
management  of  the  Fund,  no  person  beneficially  owned  5% or  more  of the
outstanding shares of the Fund.

         Compensation  of Officers and Trustees.  Commencing on January 1, 1996,
the Fund will pay an annual  trustees' fee to each Trustee who is not affiliated
with PGI, PMC, PFD or PSC consisting of two  components:  (a) a base fee of $500
and (b) a variable fee, calculated on the basis of the average net assets of the
Fund, which fee is estimated to be approximately $486 for 1996. In addition, the
Fund will pay a per  meeting fee of $120 to each  Trustee who is not  affiliated
with  PGI,  PMC,  PFD or  PSC.  The  Fund  also  will  pay an  annual  committee
participation fee to Trustees who serve as members of committees  established to
act on behalf of one or more of the of Pioneer mutual funds. Committee fees will
be  allocated  to the Fund on the basis of the Fund's  average net assets.  Each
Trustee who is a member of the Audit Committee for the Pioneer mutual funds will
receive an annual fee equal to 10% of the aggregate annual trustees' fee, except
the Committee Chair who will receive an annual trustees' fee equal to 20% of the
aggregate  annual  trustees' fee. The 1996 fees for Audit Committee  members and
the Audit Committee Chair are expected to be  approximately  $6,000 and $12,000,
respectively.  Members of the Pricing Committee for the Pioneer mutual funds, as
well as any other committee which renders  material  functional  services to the
Board of Trustees for the Pioneer mutual funds, will receive an annual fee equal
to 5% of the annual  trustees' fee,  except the Committee Chair who will receive
an annual  trustees' fee equal to 10% of the annual trustees' fee. The 1996 fees
for Pricing Committee members and the Pricing Committee Chair are expected to be
approximately $3,000 and $6,000, respectively.  Any such fees paid to affiliates
or interested  persons of PGI, PMC, PFD or PSC are  reimbursed to the Fund under
its Management Contract.

         For the fiscal year ended  December 31, 1995, the Fund paid no salaries
or compensation  to any of its officers.  The Fund paid 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 paid the Chairman of the Audit  Committee an  additional  annual fee of
$250 and paid each member of the Audit  Committee  an  additional  annual fee of
$200. All Trustees were  reimbursed for expenses  incurred in attending  Trustee
and committee meetings.  The Fund also paid 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 were
reimbursed to the Fund under its Management Contract.

         The following  table provides  information  regarding the  compensation
paid by the Fund and  other  Pioneer  mutual  funds to the  Trustees  for  their
services.

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)


                                      -15-
<PAGE>

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.

         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 agreed that until  December  1, 1995,  its fee would not exceed the
fee that would have been payable  under the previous  management  contract  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 in excess of $100,000,000
  to $200,000,000.........................................48%
For assets in excess of $200,000,000
  to $300,000,000.........................................46%
For assets in excess of $300,000,000
  to $400,000,000.........................................44%
For assets in excess of $400,000,000
  to $500,000,000.........................................42%
For assets of $500,000,000 and over.......................40%

   
         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 fee for the period for which  reimbursements,  if any, were made.
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.
    

                                      -16-
<PAGE>

   
         The Fund paid  $2,024,972 in management fees to FMC for the fiscal year
ended  December  31,  1992,  and  $2,111,066  for the period  from  January 1 to
November  30, 1993.  The Fund paid  $205,922 in  management  fees to PMC for the
period from December 1, 1993 to December 31, 1993. During the fiscal years ended
December 31, 1994 and December 31, 1995,  the Fund incurred  management  fees of
$2,226,099 and $2,153,083, respectively.
    

5. UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

         The Fund has  entered  into an  Underwriting  Agreement  with PFD.  The
Underwriting  Agreement will continue from year to year if annually  approved by
the Trustees.  The  Underwriting  Agreement  provides that PFD will bear 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 each Class of shares  (the  "Class A Plan",
"Class B Plan" and "Class C 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


                                      -17-
<PAGE>

record).  This  service  fee is  intended  to be in  consideration  of  personal
services and/or account maintenance services rendered by the dealer with respect
to Class B shares.  PFD will advance to dealers the first-year  service fee at a
rate equal to 0.25% of the amount invested.  As compensation  therefor,  PFD may
retain the  service  fee paid by the Fund with  respect  to such  shares for the
first year after purchase.  Dealers will become eligible for additional  service
fees with respect to such shares  commencing in the thirteenth  month  following
purchase.  Dealers  may from  time to time be  required  to meet  certain  other
criteria in order to receive service fees. PFD or its affiliates are entitled to
retain all  service  fees  payable  under the Class B Plan for which there is no
dealer  of  record or for  which  qualification  standards  have not been met as
partial  consideration for personal services and/or account maintenance services
performed by PFD or its affiliates for shareholder accounts.

   
         The purpose of  distribution  payments to PFD under the Class B Plan is
to  compensate  PFD  for  its  distribution  services  to  the  Fund.  PFD  pays
commissions to dealers as well as expenses of printing  prospectuses and reports
used for sales  purposes,  expenses with respect to the preparation and printing
of sales literature and other distribution related expenses,  including, without
limitation,  the cost  necessary to provide  distribution-related  services,  or
personnel,  travel office expenses and equipment. The Class B Plan also provides
that  PFD  will  receive  all  contingent   deferred  sales  charges   ("CDSCs")
attributable to Class B shares. See "Distribution Plans" in the Prospectus.

Class C Plan

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

                                      -18-
<PAGE>

   
         The purpose of  distribution  payments to PFD under the Class C Plan is
to  compensate  PFD for its  distribution  services  with respect to the Class C
shares of the Fund.  PFD pays  commissions  to  dealers as well as  expenses  of
printing prospectuses and reports used for sales purposes, expenses with respect
to   the   preparation   and   printing   of   sales    literature   and   other
distribution-related expenses, including, without limitation, the cost necessary
to provide  distribution-related  services, or personnel, travel office expenses
and  equipment.  The Class C Plan also  provides that PFD will receive all CDSCs
attributable to Class C shares. (See "Distribution Plans" in the Prospectus.)
    

General

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

   
         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,  as  defined  in the 1940 Act (none of whom had or have any
direct or indirect financial interest in the operation of the Plan) of the Fund,
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 of the outstanding  voting securities of the respective Class
of the Fund (as defined in the 1940 Act). A Plan will automatically terminate in
the event of its  assignment  (as  defined  in the 1940 Act).  In the  Trustees'
quarterly   review  of  the  Plans,   they  will  consider  a  Plan's  continued
appropriateness and the level of compensation it provides.

                                      -19-
<PAGE>

   
         During the fiscal year ended December 31, 1995, the Fund incurred total
distribution  fees  pursuant  to the  Fund's  Class A Plan  and  Class B Plan of
$1,164,136 and $6,465, respectively. The distribution fees were paid by the Fund
to PFD in reimbursement of expenses related to servicing of shareholder accounts
and to compensating  dealers and sales personnel.  The Fund had not incurred any
distribution  fees  pursuant  to the  Class C Plan.  Class C shares  were  first
offered January 31, 1996.

         During the fiscal  year  ended  December  31,  1995,  CDSCs,  at a rate
declining from a maximum of 4.0% of the lower of the cost or market value of the
shares being  redeemed,  of $275 were charged to  redemptions  of Class B shares
made within 6 years of purchase (as described in "How to Buy Fund Shares" in the
Prospectus).  Such CDSCs are paid to PFD in reimbursement of expenses related to
servicing of  shareholder  accounts and  compensation  paid to dealers and sales
personnel.
    

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 $28.00 per Class A, Class B and Class C
shareholder  account from the Fund as  compensation  for the services  described
above.  This fee is set at an amount  determined  by vote of a  majority  of the
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 


                                      -20-
<PAGE>

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, Class B and Class C shares of the Fund.  For the fiscal  year ended  December
31, 1992 and for the period from January 1, 1993 to November 30, 1993, under the
Fund's  previous  underwriting  agreement  with FMC,  commissions  retained were
$338,384 and $387,593, respectively.

         Under the Fund's current  underwriting  agreement with PFD, for (i) the
period from  December 1, 1993 to December 31,  1993,  for the fiscal years ended
December 31, 1994 and December 31, 1995, PFD received  $150,000,  $1,145,352 and
$677,682.59  for Class A shares,  respectively,  and (ii) the fiscal  year ended
December 31,  1995,  PFD received  $76,632.70  for Class B shares,  in aggregate
underwriting  income  commissions.  Of the foregoing amounts for Class A shares,
$19,058, $135,694 and $99,407, respectively, was retained and for Class B shares
$0 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) 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  broker-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

                                      -21-
<PAGE>

purchased  or  sold;  the  execution  efficiency,   settlement  capability,  and
financial condition of the broker-dealer; the broker-dealer's execution services
rendered on a continuing  basis;  and the  reasonableness  of any  broker-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 broker-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 broker-dealers who have executed
transaction  orders on behalf of such other PMC  clients may be useful to PMC in
carrying out its  obligations  to the Fund. The receipt of such research has not
reduced PMC's normal independent research activities; however, it enables PMC to
avoid the additional  expenses  which might  otherwise be incurred if it were to
attempt to develop comparable information through its own staff.

         The 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  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.

   
         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
    

                                      -22-
<PAGE>

   
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 mutual  fund or account  presently  has in a  particular
industry  and the  availability  of  investment  funds  in each  mutual  fund or
account.

         It is possible that at times identical  securities will be held by more
than one mutual fund and/or  account.  However,  positions in the same issue may
vary and the length of time that any mutual  fund or account  may choose to hold
its investment in the same issue may likewise vary. To the extent that the Fund,
another 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  mutual  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 no  brokerage  commissions  for the  fiscal  years  ended
December 31, 1992, 1993, 1994 and 1995.
    

11. TAX STATUS AND DIVIDENDS

         The Fund's policy is to declare on each business day dividends from the
Fund's net investment  income and to pay them to  shareholders  of record on the
last  business day of each month or shortly  thereafter  and to  distribute  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
Code for qualification as a regulated  investment  company.  These  requirements
relate to the sources of its income,  the  diversification of its assets and the
distribution  of  its  income  to  shareholders.  If the  Fund  meets  all  such
requirements and distributes to its shareholders,  in accordance with the Code's
timing requirements, all investment company taxable income and net capital gain,
if any,  which it earns,  the Fund will be relieved of the  necessity  of paying
federal income tax.
    

         In  accordance  with its  investment  objectives,  the Fund invests its
assets in a manner which will provide as high a level of tax-exempt income as is
consistent  with  the   preservation  of   shareholders'   capital.   Since  the
preservation  of  capital  is an  important  aspect  of  the  Fund's  investment
objectives,  the Fund may from time to time invest a portion of its portfolio in
short-term obligations and may engage in transactions  generating income or gain

                                      -23-
<PAGE>

which is not tax-exempt,  e.g., purchase non-municipal securities,  sell or lend
portfolio  securities,  enter into repurchase  agreements,  dispose of rights to
when-issued  securities prior to issuance,  acquire certain stripped  tax-exempt
obligations or coupons, acquire obligations at a market discount, and enter into
options and futures transactions.

   
         The  Code  permits  tax-exempt  interest  received  by the Fund to flow
through as  tax-exempt  exempt-interest  dividends  to the Fund's  shareholders,
provided that the Fund qualifies as a regulated  investment company and at least
50% of the value of the Fund's  total assets at the close of each quarter of its
taxable year consists of tax-exempt obligations,  i.e., obligations described in
Section 103(a) of the Code. That part of the Fund's net investment  income which
is attributable to interest from tax-exempt obligations and which is distributed
to shareholders will be designated by the Fund as an "exempt-interest  dividend"
under  the Code and will be  excluded  from a  shareholder's  gross  income  for
regular  federal  income tax purposes.  The  percentage of income  designated as
tax-exempt is applied  uniformly to all  distributions  made during each taxable
year and may differ  from the actual  tax-exempt  percentage  earned  during any
particular  month.  That  portion of net  investment  income  distributions  not
designated as tax-exempt and any  distributions  of the excess of net short-term
capital  gain over net  long-term  capital loss are taxable to  shareholders  as
ordinary income,  and any  distributions of the excess of net long-term  capital
gain over net  short-term  capital  loss (after  taking into account any capital
loss  carryovers)  are  taxable to  shareholders  as  long-term  capital  gains,
regardless  of the  shareholder's  holding  period  for  the  shares.  Dividends
declared  by the Fund in  October,  November  or December as of a record date in
such a month and paid the following  January will be treated for federal  income
tax purposes as received by  shareholders on December 31 of the calendar year in
which they are declared.

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

         For federal income tax purposes, the Fund is permitted to carry forward
a net capital loss in any year to offset 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.

         Options written or purchased and futures  contracts entered into by the
Fund on certain securities or securities indices may cause the Fund to recognize
gains or losses  from  marking  to market  at the end of its  taxable  year 


                                      -24-
<PAGE>

   
even though such options may not have  lapsed,  been closed out, or exercised or
such futures contracts may not have been offset or otherwise  terminated and may
affect the characterization as long-term or short-term of some capital gains and
losses  realized  by the Fund.  Losses on certain  options or futures  contracts
and/or  offsetting  positions  (portfolio  securities  or other  positions  with
respect to which the Fund's risk of loss is  substantially  diminished by one or
more options or futures  contracts)  may also be deferred under the tax straddle
rules of the Code, which may also affect the  characterization  of capital gains
or losses from straddle  positions and certain successor  positions as long-term
or short-term.  These tax rules applicable to options,  futures  contracts,  and
straddles  may affect the amount,  timing and character of the Fund's income and
loss and hence of its distributions to shareholders.
    

         Because none of the Fund's income will arise from dividends, no part of
its   distributions  to  its  corporate   shareholders   will  qualify  for  the
dividends-received deduction for corporations.

   
         Redemptions,  including exchanges,  are taxable transactions.  Any loss
realized by a shareholder on the  redemption,  exchange or other  disposition of
Fund shares that have a tax holding  period of six months or less is  disallowed
to the extent of any exempt-interest  dividends with respect to such shares and,
to the extent not thus disallowed,  will be treated as a long-term  capital loss
to the extent of any  distributions  of long-term  capital gains 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
redemptions  or other sales of shares may be disallowed  under "wash sale" rules
in the event of other  investments in the Fund (including by the reinvestment of
distributions) within a period of 61 days beginning 30 days before and ending 30
days after a redemption or other sale of shares.  In such a case, the disallowed
amount would be included in the federal tax basis of the newly-acquired shares.

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

         Interest on the  indebtedness  incurred  (directly  or  indirectly)  by
shareholders  to purchase or carry shares of the Fund will not be deductible for
federal   income  tax  purposes  to  the  extent  it  is  deemed  to  relate  to
exempt-interest dividends received from the Fund.

                                      -25-
<PAGE>

   
         Federal  law  generally  requires  that the Fund  withhold  as  "backup
withholding" 31% of reportable payments, including taxable income dividends (but
not  including  exempt-interest  dividends),  capital  gain  dividends,  and the
proceeds of redemptions  (including  exchanges) and  repurchases to shareholders
who have not complied with Internal  Revenue  Service  ("IRS")  regulations.  In
order to avoid this withholding requirement,  shareholders must certify on their
Account Applications,  or on separate W-9 Forms, that the Social Security Number
or other Taxpayer Identification Number they provide is their correct number and
that they are not  currently  subject  to backup  withholding,  or that they are
exempt  from  backup  withholding.  The Fund may  nevertheless  be  required  to
withhold if it receives notice from the IRS or a broker that the number provided
is  incorrect  or backup  withholding  is  applicable  as a result  of  previous
under-reporting  of interest  or  dividend  income.  Backup  withholding  may be
inapplicable  for any year in which the Fund reasonably  estimates that at least
95% of its  dividends  paid  with  respect  to  such  year  are  exempt-interest
dividends.

         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 under Delaware law, it should also not
be required to pay Delaware corporate 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, or U.S. domestic corporations,  partnerships,  trusts or estates, and
who are subject to U.S.  federal  income tax. The  description  does not address
special tax rules  applicable to certain  classes of investors such as insurance
companies and financial institutions.

         Investors other than U.S.  persons may be subject to different U.S. tax
treatment,  including a possible 30% U.S.  nonresident alien withholding tax (or
nonresident  alien withholding tax at a lower treaty rate) on amounts treated as
ordinary  dividends  from the Fund  and,  unless  an  effective  IRS Form W-8 or
authorized  substitute  is on file, to 31% backup  withholding  on certain other
payments from the Fund.

         The  exemption  of  exempt-interest  dividends  for federal  income tax
purposes  does not  necessarily  result in  exemption  under the tax laws of any
state or local taxing authority, which vary with respect to the taxation of such
dividend  income.   Many  states  will  exempt  from  tax  that  portion  of  an
exempt-interest  dividend which  represents  interest  received by the Fund from
that state's securities,  subject in some cases to compliance with concentration
and/or  reporting  requirements,  which the Fund does not make any commitment to
seek to satisfy.  However, the Fund will report annually to its shareholders the
percentage of interest  income received by the Fund during the preceding year on
municipal bonds indicating,  on a state-by-state  basis only, the source of such
income. Each shareholder is advised to consult his own tax adviser regarding the
exemption, if any, of exempt-interest dividends under applicable state and local
law.

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  Tax-Free  Income
Fund,  Inc. and prior to June 30, 1994 was called Pioneer  Tax-Free Income Fund,
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 three classes of shares,
Class A, Class B and Class C.
    

         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 Fund.  Shareholders may, under certain  circumstances  communicate
with other  shareholders  in  connection  with  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 assets 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 
    


                                      -27-
<PAGE>

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 business every weekday  except for the following  holidays:
New Year's Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day,
Labor Day,  Thanksgiving Day and Christmas Day. The net asset value per share of
each class of the Fund is also determined on any other day in which the level of
trading in its portfolio  securities is  sufficiently  high that the current net
asset  value per share might be  materially  affected by changes in the value of
its portfolio securities.  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 its
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 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  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

                                      -28-
<PAGE>

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.

14. SYSTEMATIC WITHDRAWAL PLAN

   
         The  Systematic  Withdrawal  Plan  ("SWP")  is  designed  to  provide a
convenient  method of receiving fixed payments at regular  intervals from shares
of the Fund  deposited  by the  applicant  under this SWP.  The  applicant  must
deposit or purchase for deposit with PSC shares of the Fund having a total value
of not less than $10,000.  Periodic  payments of $50 or more will be sent to the
applicant,  or any person designated by him, monthly or quarterly. A designation
of a third party to receive payments requires an acceptable signature guarantee.
SWPs for Class B and C share accounts will be limited to 10% of the value of the
account at the time the SWP is implemented as described in the Prospectus.
    

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

   
         SWP  payments are made from the  proceeds of the  redemption  of shares
deposited under the SWP in a SWP account.  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 SWP  have  been
redeemed.
    

15. LETTER OF INTENTION

         Purchases in the Fund of $100,000 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 to 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. For example, a person who signs a Letter of Intention providing for
a total  investment in Fund shares of $100,000  over a 13-month  period would be
charged at the 3.50% sales charge rate with respect to all purchases during that
period.  Should the amount actually purchased during the


                                      -29-
<PAGE>

   
13-month period be more or less than that indicated in the Letter, an adjustment
in the sales charge will be made.  A purchase  not made  pursuant to a Letter of
Intention  may be included  thereafter  if the Letter is filed within 90 days of
such  purchase.  Any  shareholder  may also obtain the reduced  sales  charge by
including the value (at current offering price) of all his Class A Shares in the
Fund and other Pioneer mutual funds, except directly purchased Class A shares of
Pioneer Money Market  Trust,  held of record as of the date of his or her Letter
of Intention as a credit toward determining the applicable scale of sales charge
for the shares to be purchased under the Letter of Intention.

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

16.  INVESTMENT RESULTS

         Other Quotations, Comparisons, and General Information

         From  time to  time,  in  advertisements,  in sales  literature,  or in
reports to  shareholders,  the past  performance  of the Fund may be illustrated
and/or  compared  with  that of  other  mutual  funds  with  similar  investment
objectives, and to other relevant indices. For example, the Fund may compare its
yield and total return to the Shearson  Lehman Hutton  Municipal Bond Index,  or
other comparable indices or investment vehicles. In addition, the performance of
the Fund may be compared to alternative  investment or savings vehicles (such as
individual securities, bank deposits, or certificates of deposit) and/or indices
or indicators of economic  activity,  e.g.,  inflation,  interest  rates, or the
Consumer Price Index,  performance  rankings and listings reported in newspapers
or national  business and  financial  publications,  such as Barron's,  Business
Week,  Consumers Digest,  Consumer Reports,  Financial World,  Forbes,  Fortune,
Investors Business Daily, Kiplinger's Personal Finance Magazine, Money Magazine,
New York Times,  Personal Investor,  Smart Money, USA Today, U.S. News and World
Report,  the Wall  Street  Journal,  and Worth may also be cited (if the Fund is
listed in any such  publication) or used for comparison,  as well as performance
listings and rankings  from various other  sources  including CDA  Weisenberger,
Donoghue's  Mutual  Fund  Almanac,   Investment  Company  Data,  Inc.,  Ibbotson
Associates,  Johnson's Charts, Kanon Bloch Carre and Company,  Lipper Analytical
Services,  Inc.,  Micropal,  Inc.,  Morningstar,   Inc.,  Schabacker  Investment
Management and Towers Data Systems, Inc.

         In addition,  from time to time quotations from articles from financial
publications  such as those listed above may be used in  advertisements in sales
literature,  or in  reports  to  shareholders  of the  Fund.  The  Fund may also
present,  from time to time,  historical  information  depicting  the value of a
hypothetical  account  in one or more  classes  of the  Fund  since  the  Fund's
inception.

                                      -30-
<PAGE>

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

         One of the  methods  used to measure the Fund's  performance  is "total
return." "Total return" will normally  represent the percentage  change in value
of an account,  or of a hypothetical  investment in the Fund, over any period up
to the lifetime of the Fund. Total return  calculations  will usually assume the
reinvestment  of all  dividends  and  capital  gains  distributions  and will be
expressed as a percentage  increase or decrease from an initial  value,  for the
entire period or for one or more  specified  periods  within the entire  period.
Total  return  percentages  for  periods  of less than one year will  usually be
annualized;  total  return  percentages  for  periods  longer than one year will
usually be  accompanied  by total  return  percentages  for each year within the
period and/or 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.

         Other data that may be advertised  or published  about the Fund include
the average portfolio quality,  the average portfolio maturity,  and the average
portfolio duration.

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

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

Standardized Yield Quotations

   
         Yield  quotations  for Class A, Class B and Class C shares are computed
by dividing the net investment income per share attributable to a class during a
base period of 30 days, or one month, by the maximum offering price per share of
that class of the Fund on the last day of such base  period in  accordance  with
the following formula:
    

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

         b        =        net expenses accrued for the period

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

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

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

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

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

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

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

          (v)  Obligations  with sinking fund call provisions may be regarded as
maturing  as to that  portion to be retired  on each  sinking  fund call date or
during a twelve-month period; and

         (vi) In the case of a tax exempt  obligation  issued  without  original
issue discount and having a current market discount, the coupon rate of interest
of the  obligation  is used in lieu of yield to maturity to  determine  interest
income earned on the  obligation.  In the case of a tax exempt  obligation  with
original  issue discount where the discount based on the current market value of
the  obligation  exceeds the then  remaining  portion of original issue discount
(i.e. market discount),  the yield to maturity used to determine interest income
earned  on the  obligation  is the  imputed  rate  based on the  original  issue
discount calculation. In the case of a tax exempt obligation with original issue
discount  where the discount based on the current market 

                                      -32-
<PAGE>

value of the obligation is less than the then remaining  portion of the original
issue  discount  (market  premium),  the  yield to  maturity  used to  determine
interest  income  earned on the  obligation  is based on the market value of the
obligation.

         Taxable Equivalent Yield

   
         The Fund may also from time to time  advertise  its taxable  equivalent
yield  which  is  determined  by  dividing  that  portion  of the  Fund's  yield
(calculated  as  described  above)  that is tax  exempt by one minus the  stated
federal  income tax rate and adding the product to that portion,  if any, of the
Fund's yield that is not tax exempt. The Fund's  tax-equivalent yield assuming a
39.6% tax rate for the period  ended  December  31,  1995 was 7.0% and 6.13% for
Class A shares and Class B shares,  respectively.  For a  description  of how to
compare  yields on  municipal  bonds and  taxable  securities,  see the  Taxable
Equivalent  Formula  set forth in Appendix A to the  Prospectus.  Class C shares
were first offered on January 31, 1996,  therefore,  no yield for Class C shares
exists at this time.
    

         Standardized Average Annual Total Return Quotations

         Average  annual  total  return  quotations  are computed by finding the
average  annual  compounded  rates of return  that  would  cause a  hypothetical
investment  made on the first  day of a  designated  period 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 for Class A
                                    Shares or the deduction of the CDSC on Class
                                    B and C Shares at the end of the period.
    

                  T        =        average annual total return

                  n        =        number of years

                  ERV      =        ending  redeemable value of the hypothetical
                                    $1,000 initial payment made at the beginning
                                    of  the  designated  period  (or  fractional
                                    portion thereof)

   
The computation above assumes 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
Fund's  average  annual  total  return  for Class A shares for the one- , five-,
ten-year and  commencement-of-fund  periods ended December 31, 1995 were 11.57%,
7.62%, 8.75% and 6.68%, respectively. The Fund's average annual total return for
Class B shares for the one-year  period ended  December 31, 1995 was 7.94%.  The
Fund's SEC yield for the 30-day period ended December 31, 1995 for Class A and B
shares was 4.23% and 3.70%, respectively.

                                   APPENDIX A


         The three highest  ratings of Moody's for Tax-Exempt  Bonds are Aaa, Aa
and A.  Tax-Exempt  Bonds rated Aaa are judged to be of the "best  quality." The
rating of Aa is assigned to  Tax-Exempt  Bonds which are of "high quality by all
standards,"  but as to  which  margins  of  protection  or other  elements  make
long-term risks appear somewhat larger than Aaa rated Tax-Exempt  Bonds. The Aaa
and Aa rated  Tax-Exempt  Bonds comprise what are generally known as "high grade
bonds."  Tax-Exempt  Bonds which are rated A by Moody's  possess many  favorable
investment  attributes  and are  considered  "upper  medium grade  obligations."
Factors giving  security to principal and interest of A rated  Tax-Exempt  bonds
are  considered   adequate,   but  elements  may  be  present  which  suggest  a
susceptibility to impairment sometime in the future.  Bonds in the A group which
offer the maximum security are rated A-1.

         The three highest ratings of S&P for Tax-Exempt  Bonds are AAA (Prime),
AA (High Grade) and A (Good Grade).  Tax-Exempt Bonds rated AAA are "obligations
of the highest  quality."  The rating of AA is accorded  issues with  investment
characteristics  "only  slightly  less  marked  than those of the prime  quality
issues." The category of A describes the "third  strongest  capacity for payment
of debt service."  Principal and interest payments on bonds in this category are
regarded as safe. It differs from the two higher ratings  because:  with respect
to general obligation bonds, there is some weakness either in the local economic
base, in debt burden,  in the balance between revenues and  expenditures,  or in
quality  of  management.  Under  certain  adverse  circumstances,  any one  such
weakness might impair the ability of the issuer to meet debt obligations at some
future date. With respect to revenue bonds,  debt service  coverage is good, but
not  exceptional.  Stability of the pledged  revenues could show some variations
because of increased  competition  or economic  influences  on  revenues.  Basic
security  provisions,  while  satisfactory,   are  less  stringent.   Management
performance appears adequate. AA and A rated bonds may be modified with a (+) or
(-) when appropriate to provide more detailed indications on credit quality.

         The "other debt  securities"  included in the  definition  of temporary
investments are corporate (as opposed to municipal)  debt obligation  rated AAA,
AA or A by S&P or Aaa, Aa or A by Moody's.  Corporate debt obligations rated AAA
by S&P are "highest  grade  obligations."  Obligations  bearing the rating of AA
also  qualify as "high grade  obligations"  and "in the  majority  of  instances
differ from AAA issues only in small degree." Corporate debt obligations rates A
by S&P are regarded as "upper  medium grade" and have  "considerable  investment
strength,  but are not entirely free from adverse effects of changes in economic
and trade  conditions."  The Moody's  corporate debt ratings of Aaa, Aa and A do
not differ materially from those set forth above for Tax-Exempt Bonds.

         The  commercial  paper ratings of A-1 by S&P and P-1 by Moody's are the
highest  commercial  paper  ratings of the  respective  agencies.  The  issuer's
earnings,  quality of long-term debt, management and industry position are among
the factors considered in assigning such ratings.

                                      -35-
<PAGE>

         Subsequent to its purchase by the Fund, an issue of Tax-Exempt Bonds or
a temporary  investment may cease to be rated or its rating may be reduced below
the minimum  required  for  purchase by the Fund.  Neither  event  requires  the
elimination of such obligation from the Fund's portfolio,  but PMC will consider
such an event in its  determination  of whether the Fund should continue to hold
such obligation in its portfolio. To the extent that the ratings accorded by S&P
and Moody's for Tax-Exempt Bonds or temporary investments may change as a result
of changes in such organizations,  or changes in their ratings systems, the Fund
will attempt to use  comparable  ratings as  standards  for its  investments  in
Tax-Exempt  Bonds or temporary  investments  in accordance  with the  investment
policies contained herein.

                             COMPARATIVE PERFORMANCE
                               INDEX DESCRIPTIONS

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

RUSSELL 2000 SMALL STOCK INDEX
Index of the 2,000 smallest  stocks in the Russell 3000 Index (TM); the smallest
company has a market capitalization of approximately $13 million.
The Russell  30000 is comprised of the 3,000  largest US companies as determined
by market capitalization representing approximately 98% of the US equity market.
The largest company in the index has a market capitalization of $67 billion. The
Russell Indexes (TM) are reconstituted  annually as of June 1st, based on May 31
market capitalization rankings.

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

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

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

Item 27.          Indemnification

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

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

                                 SALES AGREEMENT

Gentlemen:

      Pioneer Funds Distributor,  Inc. (PFD), acts as principal underwriter,  as
defined in the Investment  Company Act of 1940,  for the  registered  investment
companies  (the "Funds")  listed on Appendix A attached (as amended from time to
time by PFD.)  Acting as a  principal,  PFD  offers to sell  shares of the Funds
subject to the conditions set forth in this agreement and subsequent  amendments
thereto.

      1. Shares  purchased  from PFD for sale to the public shall be offered and
sold at the price or prices,  and on the terms and conditions,  set forth in the
currently  effective  prospectus of the Funds, as amended or  supplemented  from
time to time (the "Prospectus" or "Prospectuses"). In the sale of such shares to
the  public  you shall act as dealer  for your own  account or as agent for your
customer  and in no  transaction  shall  you have any  authority  to act or hold
yourself  out as agent for PFD,  any of the Funds,  the Funds'  Custodians,  the
Funds' Transfer  agent, or any other party,  and nothing in this agreement shall
constitute you a partner, employee or agent of ours or give you any authority to
act for PFD.  Neither  PFD nor the funds shall be liable for any of your acts or
obligations as a  broker-dealer  under this  agreement.  Nothing herein shall be
construed to prohibit your acting as agent for one or both customers in the sale
of shares by one customer to another and charging such  customer(s) a reasonable
commission.

       2. Shares  purchased  from PFD for sale to the public  shall be purchased
only to cover  orders  previously  received by you from your  customers.  Shares
purchased  for your own bona  fide  investment  shall not be  reoffered  or sold
except to the applicable Fund or to PFD. PFD also agrees to purchase shares only
for investment or to cover orders received.

       3. If you  purchase  shares  from your  customers,  you agree to pay such
customers not less than the redemption  price in effect on the date of purchase,
as defined in the prospectus of the applicable  Fund.  Sales of shares at prices
reflecting a discount, concession, commission or other reallowance shall be made
only to registered  broker-dealers which are members of the National Association
of  Securities  Dealers  Inc.  (NASD)  and who  also  have  entered  into  sales
agreements with PFD.

       4. Only unconditional  orders for a designated number of shares or dollar
amount of investment shall be accepted.  Procedures  relating to handling orders
shall be conveyed to you from time to time. All orders are subject to acceptance
or rejection by PFD in our sole discretion.

       5. If any shares sold to or through you under the terms of this agreement
are  repurchased by PFD or by the issuer or are tendered for  redemption  within
seven business days after the date of our confirmation of the original  purchase
by you, we both agree to pay to the Fund all commissions on such shares.

       6.  Sales by you to the  public  shall earn a  commission  computed  as a
percentage of the  applicable  offering price and which varies with the size and
nature of each such purchase.  The terms and conditions affecting the applicable
offering  prices  on shares  sold  with a  front-end  sales  charge ,  including
features such as combined purchase, rights of accumulation, Letters of Intention
and net asset value purchases, are described in the prospectuses.  The schedules
of commissions generally payable with respect to sales of the Funds are outlined
on Appendix A to this agreement.  Commission checks for less than $1 will not be
issued.

      PFD may, from time to time,  offer  additional  commissions  or bonuses on
sales by you or your representatives  without otherwise revising this agreement.
Any such additional  commissions or bonuses shall take effect in accordance with
the terms and conditions contained in written notification to you.

       7.  Remittance of the net amount due for shares  purchased from PFD shall
be  made  payable  to  Pioneering  Services  Corporation  (PSC)  Agent  for  the
Underwriter,  in New York or Boston funds, within three days of our confirmation
of sale to you, or within such  shorter  time as  specified  by the rules of the
NASD or of a registered clearing agent through which the transaction is settled.
Payments  made to PSC should be sent to Post Office Box 9014,  Boston,  MA 02205
(or  wired  to  an  account   designated  by  PSC),  along  with  your  transfer
instructions on the appropriate copy of our confirmation of sale to you. If such
payment is not  received by PSC, we reserve  the right to  liquidate  the shares
purchased for your account and risk.  Promptly  upon receipt of payment,  shares
sold to you shall be  deposited by PSC to an account on the books of the Fund(s)
in accordance  with your  instructions.  Certificates  will not be issued unless
specifically requested and we reserve the right to levy a charge for issuance of
certificates.

       8. You represent  that you are and, at the time of purchasing  any shares
of the Funds, will be registered as a broker-dealer  with the US. Securities and
Exchange  Commission (SEC) or are exempt from such registration;  if required to
be registered as a broker-dealer  you are a member in good standing of the NASD;
you are qualified to act as a broker-dealer  in the states or  jurisdictions  in
which you intend to offer shares of the Funds;  you will abide by all applicable
federal and state  statutes and the rules of the NASD;  and when making sales to
citizens  or  residents  of  foreign  countries,  that  you  will  abide  by all
applicable  laws and  regulations of that country.  Expulsion or suspension from
the  NASD or  revocation  or  suspension  of SEC  registration  shall  act as an
immediate cancellation of this agreement.

       9. No person is authorized to make any representations  concerning shares
of any of the Funds except those  contained  in the then current  Prospectus  or
Statement of Additional Information for such Fund. In purchasing shares from PFD
you shall rely solely on the representations  contained in such Prospectuses and
Statements of Additional Information.

      10.  Additional  copies  of  the  current   prospectuses,   Statements  of
Additional   Information  (SAI),  and  other  literature  will  be  supplied  in
reasonable quantities upon request.

      11. We reserve the right in our  discretion  to suspend  sales or withdraw
the offering of shares of any Fund  entirely.  Either party hereto has the right
to cancel this agreement  upon five days' written notice to the other party.  We
reserve  the right to amend  this  agreement  at any time and you agree  that an
order to purchase  shares of any one of the Funds  placed by you after notice of
such amendment has been sent to you shall  constitute your agreement to any such
amendment.

      12. All written communications to PFD should be sent to the above address.
All written communications to you will be sent to your address listed below.

      13. This  agreement  shall  become  effective  upon  receipt by us of your
acceptance  hereof and supersedes any prior agreement between us with respect to
the sales of Shares of any of the Funds.

      14. This  agreement  shall be  construed  in  accordance  with the laws of
Massachusetts. The parties hereby agree that all disputes between us of whatever
subject matter, whether existing on the date hereof or arising hereafter,  shall
be  submitted  to  arbitration  in  accordance  with  the then  current  Code of
Arbitration Procedure of the NASD, the Uniform Arbitration Act or similar rules.
Arbitration shall take place in the city of Boston, Massachusetts.  Any decision
that shall be made in such arbitration shall be final and binding and shall have
the  same  force  and  effect  as a  judgment  made  in  a  court  of  competent
jurisdiction.

      15. You appoint the transfer  agent for each Fund as your agent to execute
the purchase  transactions  of Shares of such Fund in accordance  with the terms
and provisions of any account,  program,  plan or service established or used by
your  customers and to confirm each  purchase to your  customers on your behalf,
except as modified in writing by the transfer agent, and you guarantee to us and
the Fund the legal capacity of your customers so purchasing  such Shares and any
other person in whose name the Shares are to be registered.

recent date from the Recording Office. In such examinations, we have assumed the
genuineness  of all  signatures,  the  conformity  to original  documents of all
documents  submitted to us as copies or drafts of documents to be executed,  and
the legal capacity of natural persons to complete the execution of documents. We
have further assumed for the purpose of this opinion: (i) the due authorization,
execution  and delivery by, or on behalf of, each of the parties  thereto of the
above-referenced  instruments,  certificates  and  other  documents,  and of all
documents  contemplated by the Governing Instrument,  the By-laws and applicable
resolutions  of the  Trustees  to be executed  by  investors  desiring to become
Shareholders;  (ii) the payment of consideration for Shares, and the application
of such consideration,  as provided in the Governing Instrument,  and compliance
with the other terms,  conditions  and  restrictions  set forth in the Governing
Instrument  and all  applicable  resolutions  of the  Trustees  of the  Trust in
connection  with the  issuance of Shares  (including,  without  limitation,  the
taking of all appropriate  action by the Trustees to designate  Series of Shares
and the rights and  preferences  attributable  thereto  as  contemplated  by the
Governing  Instrument);  (iii)  that  appropriate  notation  of  the  names  and
addresses  of, the  number of Shares  held by,  and the  consideration  paid by,
Shareholders will be maintained in the appropriate registers and other books and
records of the Trust in connection with the issuance,  redemption or transfer of
Shares;  (iv)  that no  event  has  occurred  subsequent  to the  filing  of the
Certificate that would cause a termination or  reorganization of the Trust under
Section 4 or Section 5 of Article IX of the Governing  Instrument;  (v) that the
activities of the Trust have been and will be conducted in  accordance  with the
terms of the Governing  Instrument and the Delaware  Business Trust Act, 12 Del.
C. ss.ss. 3801 et seq. (the "Delaware Act"); and (vi) that each of the documents
examined  by  us is in  full  force  and  effect  and  has  not  been  modified,
supplemented or otherwise  amended.  No opinion is expressed herein with respect
to the requirements of, or compliance with,  federal or state securities or blue
sky laws.  Further,  we express no opinion on the sufficiency or accuracy of any
registration or offering  documentation  relating to the Trust or the Shares. As
to any facts material to our opinion,  other than those assumed,  we have relied
without independent  investigation on the above-referenced  documents and on the
accuracy, as of the date hereof, of the matters therein contained.

              Based on and subject to the foregoing, and limited in all respects
to matters of Delaware law, it is our opinion that:

              1. The Trust is a duly  organized  and validly  existing  business
trust in good standing under the laws of the State of Delaware.

              2. The Shares covered by the Post-Effective Amendment, when issued
to  Shareholders  in accordance  with the terms,  conditions,  requirements  and
procedures  set  forth in the  Governing  Instrument,  will  constitute  legally
issued,  fully paid and  non-assessable  Shares of  beneficial  interest  in the
Trust.

              3.  Under  the  Delaware  Act  and  the  terms  of  the  Governing
Instrument, each Shareholder of the Trust, in such capacity, will be entitled to
the same  limitation of personal  liability as that extended to  stockholders of
private  corporations for profit organized under the general  corporation law of
the State of  Delaware;  provided,  however,  that we express  no  opinion  with
respect to the  liability of any  Shareholder  who is, was or may become a named
Trustee of the Trust.  Neither the  existence  nor exercise of the voting rights
granted to Shareholders under the Governing  Instrument will, of itself, cause a
Shareholder  to be  deemed a  trustee  of the  Trust  under  the  Delaware  Act.
Notwithstanding  the foregoing or the opinion expressed in paragraph 2 above, we
note that,  pursuant to Section 2 of Article VIII of the  Governing  Instrument,
the  Trustees  have the  power  to  cause  Shareholders,  or  Shareholders  of a
particular  Series,  to pay certain  custodian,  transfer,  servicing or similar
agent charges by setting off the same against  declared but unpaid  dividends or
by reducing Share ownership (or by both means).

              We hereby consent to the filing of a copy of this opinion with the
Securities and Exchange Commission as part of the Post-Effective  Amendment.  In
giving this consent, we do not thereby admit that we come within the category of
persons whose consent is required under Section 7 of the Securities Act of 1933,
as  amended,  or the  rules  and  regulations  of the  Securities  and

                        CLASS C SHARES DISTRIBUTION PLAN

                          PIONEER TAX-FREE INCOME FUND


     CLASS C SHARES  DISTRIBUTION  PLAN, dated as of January 31, 1996 of PIONEER
TAX-FREE INCOME FUND, a Delaware business trust (the "Trust").

                                   WITNESSETH

     WHEREAS,  the Trust is engaged in  business  as an  open-end,  diversified,
management investment company and is registered under the Investment Company Act
of 1940, as amended  (collectively  with the rules and  regulations  promulgated
thereunder, the "1940 Act");

     WHEREAS, the Trust intends to distribute shares of beneficial interest (the
"Class C Shares") of the Trust in accordance with Rule 12b-1  promulgated by the
Securities  and  Exchange  Commission  under the 1940 Act  ("Rule  12b-1"),  and
desires to adopt this Class C Shares distribution plan (the "Class C Plan") as a
plan of distribution pursuant to such Rule;

     WHEREAS,  the  Trust  desires  that  Pioneer  Funds  Distributor,  Inc.,  a
Massachusetts corporation ("PFD"), provide certain distribution services for the
Trust's Class C Shares in connection with the Class C Plan;

     WHEREAS,  the Trust has entered into an  underwriting  agreement (in a form
approved by the Trust's  Board of  Trustees in a manner  specified  in such Rule
12b-1) with PFD,  whereby PFD  provides  facilities  and  personnel  and renders
services to the Trust in connection with the offering and  distribution of Class
C Shares (the "Underwriting Agreement");

     WHEREAS,  the Trust also  recognizes and agrees that (a) PFD may retain the
services of firms or individuals to act as dealers or wholesalers (collectively,
the "Dealers") of the Class C Shares in connection  with the offering of Class C
Shares,  (b) PFD may  compensate  any Dealer  that  sells  Class C Shares in the
manner and at the rate or rates to be set forth in an agreement  between PFD and
such Dealer and (c) PFD may make such  payments to the Dealers for  distribution
services  out of the fee  paid to PFD  hereunder,  any  deferred  sales  charges
imposed by PFD in connection with the repurchase of Class C shares,  its profits
or any other source available to it;
<PAGE>

     WHEREAS,  the Trust  recognizes  and  agrees  that PFD may  impose  certain
deferred  sales charges in connection  with the  repurchase of Class C Shares by
the Trust,  and PFD may retain (or receive  from the Trust,  as the case may be)
all such deferred sales charges; and

     WHEREAS,  the Board of Trustees of the Trust,  in  considering  whether the
Trust  should  adopt  and  implement  this  Class C  Plan,  has  evaluated  such
information  as it deemed  necessary to an informed  determination  whether this
Class C Plan should be adopted and implemented and has considered such pertinent
factors as it deemed necessary to form the basis for a decision to use assets of
the Trust for such  purposes,  and has  determined  that  there is a  reasonable
likelihood  that the  adoption  and  implementation  of this  Class C Plan  will
benefit the Trust and its Class C shareholders;

     NOW, THEREFORE, the Board of Trustees of the Trust hereby adopts this Class
C Plan for the Trust as a plan of  distribution  of Class C Shares in accordance
with Rule 12b-1, on the following terms and conditions:

     I.  (a) The Trust is  authorized  to  compensate  PFD for (1)  distribution
         services and (2) personal and account  maintenance  services  performed
         and expenses  incurred by PFD in  connection  with the Trust's  Class C
         Shares.  Such  compensation  shall be calculated  and accrued daily and
         paid  monthly or at such other  intervals  as the Board of Trustees may
         determine.

                      (b) The amount of  compensation  paid  during any one year
              for distribution  services with respect to Class C Shares shall be
              .75% of the Trust's average daily net assets attributable to Class
              C Shares for such year.

                      (c)  Distribution  services and expenses for which PFD may
              be compensated pursuant to this Plan include,  without limitation:
              compensation to and expenses (including allocable overhead, travel
              and telephone expenses) of (i) Dealers,  brokers and other dealers
              who are members of the National Association of Securities Dealers,
              Inc.  ("NASD")  or  their  officers,   sales  representatives  and
              employees,  (ii)  PFD and any of its  affiliates  and any of their
              respective officers,  sales  representatives and employees,  (iii)
              banks and their officers, sales representatives and employees, who
              engage in or support  distribution  of the Trust's Class C Shares;
              printing  of reports  and  prospectuses  for other  than  existing
              shareholders; and preparation,  printing and distribution of sales
              literature and advertising materials.

                                      -2-
<PAGE>

                      (d) The amount of  compensation  paid  during any one year
              for personal and account  maintenance  services and expenses shall
              be .25% of the Trust's  average daily net assets  attributable  to
              Class C  Shares  for  such  year.  As  partial  consideration  for
              personal services and/or account maintenance  services provided by
              PFD to the Class C Shares,  PFD shall be  entitled  to be paid any
              fees payable  under this clause (d) with respect to Class C shares
              for  which  no  dealer  of  record  exists,  where  less  than all
              consideration  has  been  paid to a  dealer  of  record  or  where
              qualification standards have not been met.

                      (e)  Personal and account  maintenance  services for which
              PFD or any of its affiliates,  banks or Dealers may be compensated
              pursuant to this Plan include,  without limitation:  payments made
              to or on account  of PFD or any of its  affiliates,  banks,  other
              brokers  and  dealers  who  are  members  of the  NASD,  or  their
              officers,  sales  representatives  and  employees,  who respond to
              inquiries of, and furnish  assistance to,  shareholders  regarding
              their ownership of Class C Shares or their accounts or who provide
              similar  services  not  otherwise  provided by or on behalf of the
              Trust.

                      (f) PFD may  impose  certain  deferred  sales  charges  in
              connection  with the repurchase of Class C Shares by the Trust and
              PFD may retain (or receive  from the Trust as the case may be) all
              such deferred sales charges.

                      (g)  Appropriate  adjustments to payments made pursuant to
              clauses  (b) and (d) of this  paragraph  1 shall be made  whenever
              necessary to ensure that no payment is made by the Trust in excess
              of the  applicable  maximum cap imposed on asset based,  front-end
              and  deferred  sales  charges by  subsection  (d) of Section 26 of
              Article III of the Rules of Fair Practice of the NASD.

     II. The Trust  understands  that  agreements  between  PFD and  Dealers may
provide  for payment of fees to Dealers in  connection  with the sale of Class C
Shares and the provision of services to  shareholders  of the Trust.  Nothing in
this Class C Plan shall be construed as requiring  the Trust to make any payment
to any  Dealer  or to have any  obligations  to any  Dealer in  connection  with
services as a dealer of the Class C Shares.  PFD shall agree and undertake  that
any  agreement  entered into between PFD and any Dealer shall  provide that such
Dealer shall look solely to PFD for compensation for its services thereunder and
that in no event shall such Dealer seek any payment from the Trust.

                                      -3-
<PAGE>

     III.  Nothing herein contained shall be deemed to require the Trust to take
any  action  contrary  to its  Declaration  of Trust,  as it may be  amended  or
restated from time to time, or By-Laws or any applicable statutory or regulatory
requirement  to which it is  subject  or by which it is bound,  or to relieve or
deprive the Trust's Board of Trustees of the  responsibility  for and control of
the conduct of the affairs of the Trust.

     IV.  This  Class C Plan  shall  become  effective  upon  approval  by (i) a
"majority of the outstanding  voting securities" of Class C of the Trust, (ii) a
vote of the Board of  Trustees,  and (iii) a vote of a majority of the  Trustees
who are not "interested persons" of the Trust and who have no direct or indirect
financial  interest in the  operation  of the Class C Plan or in any  agreements
related to the Class C Plan (the "Qualified Trustees"),  such votes with respect
to (ii) and (iii) above to be cast in person at a meeting called for the purpose
of voting on this Class C Plan.

     V. This Class C Plan will remain in effect indefinitely, provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such  annual  approval  is not  obtained,  this Class C Plan shall  expire on
January 31, 1997.

     VI. This Class C Plan may be amended at any time by the Board of  Trustees,
provided  that this Class C Plan may not be amended to increase  materially  the
limitations on the annual percentage of average net assets which may be expended
hereunder  without the  approval of holders of a  "majority  of the  outstanding
voting  securities" of Class C of the Trust and may not be materially amended in
any case  without a vote of a majority of both the  Trustees  and the  Qualified
Trustees.  This  Class  C Plan  may be  terminated  at any  time  by a vote of a
majority of the Qualified Trustees or by a vote of the holders of a "majority of
the outstanding voting securities" of Class C of the Trust.

     VII. The Trust and PFD shall provide to the Trust's Board of Trustees,  and
the Board of Trustees shall review, at least quarterly,  a written report of the
amounts  expended  under  this  Class C Plan and the  purposes  for  which  such
expenditures were made.

     VIII. While this Class C Plan is in effect, the selection and nomination of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

                                      -4-
<PAGE>

     IX.  For the  purposes  of  this  Class C  Plan,  the  terms  "assignment,"
"interested  persons,"  "majority  of the  outstanding  voting  securities"  and
"specifically approved at least annually" are used as defined in the 1940 Act.

     X. The Trust shall preserve copies of this Class C Plan, and each agreement
related hereto and each report referred to in Paragraph 7 hereof  (collectively,
the "Records"),  for a period of not less than six (6) years from the end of the
fiscal year in which such  Records were made and, for a period of two (2) years,
each of such Records shall be kept in an easily accessible place.

     XI. This Class C Plan shall be construed in accordance with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

     XII. If any provision of this Class C Plan shall be held or made invalid by
a court decision,  statute, rule or otherwise, the remainder of the Class C Plan
shall not be affected thereby.

                          PIONEER TAX-FREE INCOME FUND

                   Multiple Class Plan Pursuant to Rule 18f-3

                        Class A Shares and Class B Shares

                                December 5, 1995


     Each class of shares of PIONEER  TAX-FREE  INCOME FUND (the  "Fund"),  will
have the same relative  rights and  privileges  and be subject to the same sales
charges, fees and expenses,  except as set forth below. The Board of Trustees of
the Fund may  determine  in the  future  that other  distribution  arrangements,
allocations of expenses  (whether  ordinary or  extraordinary) or services to be
provided to a class of shares are  appropriate  and amend this Plan  accordingly
without the approval of  shareholders  of any class.  Except as set forth in the
Fund's prospectus,  shares may be exchanged only for shares of the same class of
another Pioneer mutual fund.

     Article I.  Class A Shares

     Class A Shares are sold at net asset value and subject to the initial sales
charge  schedule  or  contingent  deferred  sales  charge  ("CDSC")  and minimum
purchase  requirements  as set forth in the  Fund's  prospectus.  Class A Shares
shall be entitled to the shareholder services set forth from time to time in the
Fund's prospectus with respect to Class A Shares.  Class A Shares are subject to
fees calculated as a stated percentage of the net assets attributable to Class A
shares  under the Fund's  Class A Rule 12b-1  Distribution  Plan as set forth in
such  Distribution  Plan. The Class A Shareholders have exclusive voting rights,
if any,  with  respect to the Class A Rule  12b-1  Distribution  Plan.  Transfer
agency fees are allocated to Class A Shares on a per account basis except to the
extent,  if any, such an allocation  would cause the Fund to fail to satisfy any
requirement  necessary  to obtain or rely on a private  letter  ruling  from the
Internal Revenue Service ("IRS") relating to the issuance of multiple classes of
shares.  Class A shares  shall  bear the  costs  and  expenses  associated  with
conducting a shareholder meeting for matters relating to Class A shares.

     Article II.  Class B Shares

     Class B Shares are sold at net asset value per share without the imposition
of an initial sales charge.  However, Class B shares redeemed within a specified
number of years of purchase will be subject to a CDSC as set forth in the Fund's
prospectus. Class B Shares are sold subject to the minimum purchase requirements
set forth in the Fund's  prospectus.  Class B Shares  shall be  entitled  to the
shareholder  services set forth from time to time in the Fund's  prospectus with
respect to Class B Shares. 

<PAGE>

Class B Shares are subject to fees calculated as a stated  percentage of the net
assets  attributable to Class B shares under the Class B Rule 12b-1 Distribution
Plan as set forth in such  Distribution  Plan. The Class B  Shareholders  of the
Fund have exclusive  voting  rights,  if any, with respect to the Fund's Class B
Rule 12b-1  Distribution  Plan.  Transfer  agency fees are  allocated to Class B
Shares on a per account  basis except to the extent,  if any, such an allocation
would cause the Fund to fail to satisfy any  requirement  necessary to obtain or
rely on a  private  letter  ruling  from the IRS  relating  to the  issuance  of
multiple  classes of shares.  Class B shares  shall bear the costs and  expenses
associated with conducting a shareholder meeting for matters relating to Class B
shares.

     Class B Shares will automatically  convert to Class A Shares of the Fund at
the end of a specified  number of years after the initial purchase date of Class
B shares,  except as provided in the Fund's  prospectus.  Such  conversion  will
occur at the  relative  net  asset  value per share of each  class  without  the
imposition of any sales charge,  fee or other charge.  The conversion of Class B
Shares  to  Class  A  Shares  may be  suspended  if it is  determined  that  the
conversion  constitutes or is likely to constitute a taxable event under federal
income tax law.

     The  initial  purchase  date  for  Class  B  shares  acquired  through  (i)
reinvestment  of  dividends  on Class B Shares  or (ii)  exchange  from  another
Pioneer  mutual fund will be deemed to be the date on which the original Class B
shares were purchased.

     Article III.     Approval by Board of Trustees

     This Plan shall not take effect until it has been approved by the vote of a
majority (or whatever  greater  percentage  may,  from time to time, be required
under Rule 18f-3  under the  Investment  Company  Act of 1940,  as amended  (the
"Act")) of (a) all of the  Trustees of the Fund,  and (b) those of the  Trustees
who are not  "interested  persons" of the Fund, as such term may be from time to
time defined under the Act.

     Article IV.      Amendments

     No material  amendment to the Plan shall be effective unless it is approved
by the Board of Trustees in the same manner as is provided  for approval of this
Plan in Article III.

occur at the  relative  net  asset  value per share of each  class  without  the
