Class A and Class B Shares 
Prospectus 
October 27, 1995 
    

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

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

information about the Fund that you should know before investing in the Fund. 
Please read and retain it for your future reference. More information about 
the Fund is included in the Statement of Additional Information (Part B of 
the Registration Statement), also dated October 27, 1995, which is 
incorporated into this Prospectus by reference. A copy of the Statement of 
Additional Information and the Fund's most recent Annual Report may be

(1) Purchases of $1,000,000 or more and certain purchases by participants in 
    a group plan ("Group Plan") are not subject to an initial sales charge 
    but may be subject to a contingent deferred sales charge as further 
    described under "How to Buy 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, 
assuming a 5% annual return and redemption at the end of each of the time 
periods: 

   

                        1 Year   3 Years   5 Years    10 Years

Class A Shares          $56      $80       $105       $177 
Class B Shares

  complete 
  redemption at end 
  of period             $60      $92       $126       $230* 
 - Assuming no 
  redemption            $20      $62       $106       $230* 

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


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

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

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

III. INVESTMENT OBJECTIVES AND POLICIES 
    

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

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

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

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

   
   The Fund may invest in the following mortgage-backed securities. 
Collateralized mortgage obligations ("CMOs") are obligations fully 
collateralized by a portfolio of mortgages or mortgage-related securities. 
Payments of principal and interest on the mortgages are passed to a special 
purpose entity, then through to the holders of the CMOs on the same schedule 
as they are received, although certain classes of CMOs have priority over 
others with respect to the receipt of prepayments on the mortgages. 
Therefore, depending on the type of CMOs in which the Fund invests, the 
investment may be subject to a greater or lesser risk of prepayment than 
other types of mortgage-related securities. A real estate mortgage investment 
conduit ("REMIC") is a form of CMO that qualifies for special tax treatment 
under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund 
may acquire "regular" interests in REMICs but does not intend, under current 
tax law, to acquire residual interests in REMICs. Mortgage-backed securities 
are derivative securities and provide for payments based on or derived from 
the performance of the underlying mortgage assets. Risks associated with 
mortgage-backed securities include the failure of a counter-party to meet its 
commitments, adverse interest rate changes and the effects of prepayments on 
mortgage cash flows. When interest rates decline, the value of an investment 
in debt obligations can be expected to rise. Conversely, when interest rates 
rise the value of an investment in debt obligations can be expected to 
decline. Like other debt obligations, when interest rates rise the value of a 
mortgage-backed security generally will decline; however, when interest rates 
are declining, the value of mortgage-backed securities with prepayment 
features may not increase as much as that of other debt obligations. 
Mortgage-backed securities may be less effective than traditional debt 
obligations of similar maturity at maintaining yields during periods of 
declining interest rates. 
    

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

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

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

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

   The foregoing objectives and investment policies (other than the 
discussion of "cycle analysis") may not be changed 

                                      4

without shareholder approval. Government securities include U.S. Treasury 
obligations such as bills, bonds and notes which principally differ in their 
interest rates, maturities and times of issuance, and obligations issued or 
guaranteed by U.S. Government agencies or instrumentalities supported by the 
full faith and credit of the U.S. Treasury (securities of the Government 
National Mortgage Association, "GNMA"), the authority of the U.S. Government 
to purchase certain obligations of the issuer (securities of the Federal 
National Mortgage Association, "FNMA"), the limited authority of the issuer 
to borrow from the U.S. Treasury (securities of the Student Loan Marketing 
Association) or only the credit of the issuer. No assurance can be given that 
the U.S. Government will provide financial support to U.S. Government 
agencies or instrumentalities in the future, other than as set forth above, 
since it is not legally obligated to do so. Interest payments of U.S. 
Treasury obligations are generally fixed. Other investment policies and 
restrictions on investment are described in the Statement of Additional 
Information, including a policy on lending portfolio securities. Since all 
investments are subject to inherent market risks and fluctuations in value 
due to earnings, economic conditions and other factors, the Fund, of course, 
cannot assure that its investment objectives will be achieved. 
    

IV. MANAGEMENT OF THE FUND 

   
   The Fund's Board of Trustees has overall responsibility for management and 
supervision of the Fund. There are currently eight Trustees, six of whom are 
not "interested persons" of the Fund as defined in the Investment Company Act 
of 1940, as amended (the "1940 Act"). The Board meets at least quarterly. By 
virtue of the functions performed by PMC as investment adviser, the Fund 
requires no employees other than its executive officers, all of whom receive 
their compensation from PMC or other sources. The Statement of Additional 
Information contains the names and general background of each Trustee and 
executive officer of the Fund. 
    

   
   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, and 
a Portfolio Management Committee, which consists of PMC's fixed income 
portfolio managers. Both committees are 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 and 
has been responsible for the day-to-day management of the Fund since March 
1988. 
    

   
   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 Board of 
Trustees. PMC is a wholly-owned subsidiary of The Pioneer Group, Inc. 
("PGI"), a Delaware corporation. Pioneer Funds Distributor, Inc. ("PFD"), an 
indirect wholly-owned subsidiary of PGI, is the principal underwriter of 
shares of the Fund. 
    

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

   Under the terms of its contract with the Fund, PMC assists in the 
management of the Fund and is authorized in its discretion to buy and sell 
securities for the account of the Fund. PMC pays all the ordinary operating 
expenses, including executive salaries and the rental of certain office 
space, related to its services for the Fund with the exception of the 
following which are to be paid by the Fund: (a) charges and expenses for fund 
accounting, pricing and appraisal services and related overhead, including, 
to the extent such services are performed by personnel of PMC or its 
affiliates, office space and facilities and personnel compensation, training 
and benefits; (b) the charges and expenses of auditors; (c) the charges and 
expenses of any custodian, transfer agent, plan agent, dividend disbursing 
agent and registrar appointed by the Fund; (d) issue and transfer taxes, 
chargeable to the Fund in connection with securities transactions to which 
the Fund is a party; (e) insurance premiums, interest charges, dues and fees 
for membership in trade associations, and all taxes and corporate fees 
payable by the Fund to federal, state or other governmental agencies; (f) 
fees and expenses involved in registering and maintaining registrations of 
the Fund and/or its shares with the SEC, individual states or blue sky 
securities agencies, territories and foreign countries, including the 
preparation of Prospectuses and Statements of Additional Information for 
filing with the SEC; (g) all expenses of shareholders' and Trustees' meetings 
and of preparing, printing and distributing prospectuses, notices, proxy 
statements and all reports to shareholders and to governmental agencies; (h) 
charges and expenses of legal counsel to the Fund and the Trustees; (i) 
distribution fees paid by the Fund in accordance with Rule 12b-1 promulgated 
by the SEC pursuant to the 1940 Act; (j) compensation of those Trustees of 
the Fund who are not affiliated with or interested persons of PMC, the Fund 
(other than as Trustees), PGI or PFD; (k) the cost of preparing and printing 
share certificates; and (l) interest on borrowed money, if any. In addition 
to the expenses described above, the Fund shall pay all brokers' and 
underwriting commissions chargeable to the Fund in connection with securities 
transactions to which the Fund is a party. 

   
   Orders for the Fund's portfolio securities transactions are placed by PMC, 
which strives to obtain the best price and execution for each transaction. In 
circumstances in which two or more broker-dealers are in a position to offer 
comparable prices and execution, consideration may be given to whether the 
broker-dealer provides investment research or brokerage services or sells 
shares of 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 and certain expenses which PMC 
incurs, PMC is entitled to a manage-

ment fee equal to 0.50% per annum of the Fund's average daily net assets. The 
fee is normally computed daily and paid monthly. During the fiscal year ended 
June 30, 1995, the Fund incurred expenses of approximately $1,271,000, 
including management fees paid or payable to PMC of $546,000. 
    

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

V. FUND SHARE ALTERNATIVES 

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

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

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

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

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

VI. SHARE PRICE 

   Shares of the Fund are sold at the public offering price, which is the net 
asset value per share plus the applicable sales charge. Net asset value per 
share of 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. 

VII. HOW TO BUY FUND SHARES 

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

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

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

   
   You are strongly urged to consult with your financial representative prior 
to requesting a telephone purchase. To purchase shares by telephone, you must 
establish your bank account of record by completing the appropriate section 
of your Account Application or an Account Options Form. PCS will 
electronically debit the amount of each purchase from this predesignated bank 
account. Telephone purchases may 
    


                                      6 


<PAGE>
 
   
not be made for 30 days after the establishment of your bank of record or any 
change to your bank information. 
    

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

   
Class A Shares 
    

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

                            Sales Charge as a % of 
                           -------------------------

   No sales charge is payable at the time of purchase on investments of 
$1,000,000 or more or for participants in certain Group Plans (described 
below) subject to a CDSC of 1% which may be imposed in the event of a 
redemption of Class A shares within 12 months of purchase. See "How to Sell 
Fund Shares." PFD may, in its discretion, pay a commission to broker-dealers 
who initiate and are responsible for such purchases as follows: 1% on the 
first $5 million invested; 0.50% on the next $45 million; and 0.25% on the 
excess over $50 million. 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 "Waiver or Reduction of Contingent 
Deferred Sales Charge." These commissions will not be paid if the purchaser 
is affiliated with the broker-dealer or if the purchase represents the 
reinvestment of a redemption made during the previous 12 calendar months. In 
connection with PGI's acquisition of Mutual of Omaha Fund Management Company 
and contingent upon the achievement of certain sales objectives, PFD pays to 
Mutual of Omaha Investor Services, Inc. 50% of PFD's retention of any sales 
commission on sales of the Fund's Class A shares through such dealer. 
    

   
   The schedule of sales charges above is applicable to purchases of Class A 
shares of the Fund by (i) an individual, (ii) an individual and his or her 
spouse and children under the age of 21 and (iii) a trustee or other 
fiduciary of a trust estate or fiduciary account or related trusts or 
accounts including pension, profit-sharing and other employee benefit trusts 
qualified under Section 401 or 408 of the Code, although more than one 
beneficiary is involved. The sales charges applicable to a current purchase 
of Class A shares of the Fund by a person listed above is determined by 
adding the value of shares to be purchased to the aggregate value (at the 
then current offering price) of shares of any of the other Pioneer mutual 
funds previously purchased and then owned, provided PFD is notified by such 
person or his or her broker-dealer each time a purchase is made which would 
qualify. Pioneer mutual funds include all mutual funds for which PFD serves 
as principal underwriter. 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 under 
which a sponsoring organization makes recommendations to, permits group 
solicitation of, or otherwise facilitates purchases by, its employees, 
members or participants. Class A shares of a Fund may be sold at net asset 
value per share without a sales charge to Optional Retirement Program 
participants if (i) the employer has authorized a limited number of 
investment company providers for the Program, (ii) all authorized investment 
company providers offer their shares to Program participants at net asset 
value, (iii) the employer has agreed in writing to actively promote the 
authorized investment providers to Program participants and (iv) the Program 
provides for a matching contribution for each participant contribution. 
Information about such arrangements is available from PFD. 
    

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

   Reduced sales charges 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, 

                                      7 

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

   
Class B Shares 
    

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

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

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

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

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

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

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

   The CDSC on Class B shares and on any Class A shares subject to a CDSC may 
be waived or reduced for retirement plan accounts if: (a) the redemption 
results from the death or a total and permanent disability (as defined in 
Section 72 of the Code) occurring after the purchase of the shares being 
redeemed of a shareholder or participant in an employer-sponsored retirement 
plan; (b) the distribution is to a participant in an IRA, 403(b) or 
employer-sponsored retirement plan, is part of a series of substantially 
equal payments made over the life expectancy of the participant or the joint 
life expectancy of the participant and his or her beneficiary or as scheduled 
periodic payments to a participant (limited in any year to 10% of the value 
of the participant's account at the time the distribution amount is 
established; a required minimum distribution due to the participant's 
attainment of age 70-1/2 may exceed the 10% limit only if the distribution 
amount is based on plan assets held by Pioneer) or a qualifying hardship 
distribution as defined by the Code or results from a termination of 
employment (limited with respect to a termination to 10% per year of the 
value of the plan's assets in the Fund as of the later of the prior December 
31 or the date the account was established unless the plan's assets are being 
rolled over to or reinvested in the same class of shares of a Pioneer mutual 
fund subject to the CDSC of the shares originally held); (c) the distribution 
is from a 401(a) or 

                                      8 

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

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

   Broker-Dealers. An order for either Class of Fund shares received by PFD 
from a broker-dealer prior to the close of regular trading on the Exchange is 
confirmed at the price appropriate for that Class as determined at the close 
of regular trading on the Exchange on the day the order is received, provided 
the order is received 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 and accepted less any applicable CDSC. Sale proceeds 
generally will be sent to you in cash, normally within seven days after your 
order is accepted. The Fund reserves the right to withhold payment of the 
sale proceeds until checks received by the Fund in payment for the shares 
being sold have cleared, which may take up to 15 calendar days from the 
purchase date. 

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

   
   Your request should include your name, the Fund's name, your fund account 
number, the Class of shares to be redeemed, the dollar amount or number of 
shares to be redeemed, and meet any other applicable requirements as 
described below. Unless instructed otherwise, PSC will send the proceeds of 
the sale to the address of record. Fiduciaries 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, any certificates are 
endorsed by the record owner(s) exactly as the shares are registered and the 
signature(s) are guaranteed by an eligible guarantor. You should be able to 
obtain a signature guarantee from a bank, broker, dealer, credit union (if 
authorized under state law), securities exchange or association, clearing 
agency or savings association. A notary public cannot provide a signature 
guarantee. Signature guarantees are not accepted by facsimile ("fax"). For 
additional information about the necessary documentation for redemption by 
mail, please contact PSC at 1-800-225-6292. 
    

   
   By Telephone or by Fax. Your account is automatically authorized to have 
the telephone redemption privilege unless you indicated otherwise on your 
Account Application or by writing to PSC. Proper account identification will 
be required for each telephone redemption. The telephone redemption option is 
not available to retirement plan accounts. A maximum of $50,000 per account 
per day may be redeemed by telephone or fax and the proceeds may be received 
by check or by bank wire or electronic funds transfer. To receive the 
proceeds by check: the check must be made payable exactly as the account is 
registered and the check must be sent to the address of record which must not 
have changed in the last 30 days. To receive the proceeds by bank wire or by 
electronic funds transfer: the proceeds must be sent to your bank wire 
address of record which must have been properly pre- 
    


                                      9

designated either on your Account Application or on an Account Options Form 
and which must not have changed in the last 30 days. To redeem by fax send 
your redemption request to 1-800-225-4240. You may always elect to deliver 
redemption instructions to PSC by mail. See "Telephone Transactions and 
Related Liabilities" below. Telephone and fax redemptions will be priced as 
described above. You are strongly urged to consult with your financial 
representative prior to requesting a telephone redemption. 
    

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

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

   
   CDSC on Class A Shares. Purchases of Class A shares of $1,000,000 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 
Fund out of which you wish to exchange and the name of the 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 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. 
    

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

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

                                      10 

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

   
   You should consider the differences in objectives and policies of the 
Pioneer mutual funds, as described in each fund's current prospectus, before 
making any exchange. To prevent abuse of the exchange privilege to the 
detriment of other Fund shareholders, the Fund and PFD reserve the right to 
limit the number and/or frequency of exchanges and/or to charge a fee for 
exchanges. The exchange privilege may be changed or discontinued and may be 
subject to additional limitations, including certain restriction on purchases 
by market timer accounts. 
    

X. DISTRIBUTION PLANS 

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

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

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

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

   Commissions of 4%, equal to 3.75% of the amount invested and a first 
year's service fee equal to 0.25% of the amount invested in Class B shares, 
are paid to broker-dealers who have selling agreements with PFD. PFD may 
advance to dealers the first year service fee at a rate up to 0.25% of the 
purchase price of such shares and, as compensation therefore, PFD may retain 
the service fee paid by the Fund with respect to such shares for the first 
year after purchase. Dealers will become eligible for additional service fees 
with respect to such shares commencing in the 13th month following the 
purchase. Dealers may from time to time be required to meet certain criteria 
in order to receive service fees. PFD or its affiliates are entitled to 
retain all service fees payable under the Class B Plan for which there is no 
dealer of record or for which qualification standards have not been met as 
partial consideration for personal services and/or account maintenance 
services performed by PFD or its affiliates for shareholder accounts. 

XI. Dividends, Distributions and Taxation 

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

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

   Each business day the Fund declares a dividend consisting of substantially 
all of its net investment income (earned interest income less expenses). 
Shares being purchased will begin earning dividends on the first business day 
following receipt of payment for purchased shares. Shares continue to earn 
dividends up to and including the date of redemption. Dividends are normally 
paid on the last business day of the month or shortly thereafter. 
Distributions from net short-term capital gains, if 

                                      11 

<PAGE>
 
   
any, may be paid with such dividends; distributions from income and/or 
capital gains may also be made at such times as may be necessary to avoid 
federal income or excise tax. 
    

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

   
   The Fund's dividends from its net investment income, income from 
securities lending, and certain net realized foreign exchange gains, and any 
net short-term capital gains 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. 
    

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

   
   Dividends and other distributions and the proceeds of redemptions, 
exchanges or repurchase of Fund shares paid to individuals and other 
non-exempt payees will be subject to a 31% backup withholding of federal 
income tax if the Fund is not provided with the shareholder's correct 
taxpayer identification number and certification that the number is correct 
and the shareholder is not subject to such backup withholding or if the Fund 
receives notice from the IRS or a broker that such withholding applies. 
Please refer to the Account Application for additional information. 
    

   
   The description above relates only to 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 securities, provided in some states that certain thresholds for 
holdings of such securities and/or reporting requirements are satisfied. The 
Fund will report annually to its shareholders the percentage of interest 
income earned from such U.S. government securities during the preceding year. 
Non-U.S. shareholders and tax-exempt shareholders are subject to different 
tax treatment that is not described above. Shareholders should consult their 
own tax 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 Shareholder Services, Pioneering 
Services Corporation, P.O. Box 9014, Boston, Massachusetts 02205-9014. Brown 
Brothers Harriman & Co. (the "Custodian") serves as the custodian of the 
Fund's securities and other assets. The principal business address of the 
mutual fund division of the Custodian is 40 Water Street, Boston, 
Massachusetts 02109. 

Account and Confirmation Statements 

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

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

Additional Investments 

   Additions to a shareholder's account may be made by sending a check 
(minimum of $50 for Class A shares and $500 for Class B shares) to PSC 
(account number and Class of shares should be clearly indicated). The bottom 
portion of a confirmation statement may be used as a remittance slip to make 
additional investments. Additions to a shareholder's account, whether by 
check or through an Investomatic Plan, are invested in full and fractional 
shares of the Fund at the applicable offering price in effect as of the close 
of regular trading on the Exchange on the day of receipt. 

Automatic Investment Plans 

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

Financial Reports and Tax Information 

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

                                      12 

<PAGE>
 
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 an account with a net asset value of less than $500. 
Changes in the distribution option 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. The value of 
this second account must be at least $1,000 ($500 for Pioneer Fund or Pioneer 
II). Invested dividends may be in any amount. There are no fees or charges 
for this service. Retirement plan shareholders may only direct dividends to 
accounts with identical registrations i.e., PGI IRA Cust for John Smith may 
only go into another account registered PGI IRA Cust for John Smith. 
    

Direct Deposit 

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

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

   
FactFone(SM) 
    

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

Retirement Plans 

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

Telecommunications Device for the Deaf (TDD) 

   If you have a hearing disability and you 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 
SWP providing for fixed payments at regular intervals. Withdrawals from Class 
B share accounts are limited to 10% of the value of the account at the time 
the plan is implemented. See "Waiver or Reduction of Contingent Deferred 
Sales 
    


                                      13 

<PAGE>
 
Charge" for more information. Periodic checks of $50 or more will be sent to 
you, or any person designated by you, monthly or quarterly and your periodic 
redemptions of shares may be taxable to you. You may also direct that 
withdrawal checks be paid to another person, although if you make this 
designation after you have opened your account, a signature guarantee must 
accompany your instructions. Purchases of Class A shares of the Fund at a 
time when you have a SWP in effect may result in the payment of unnecessary 
sales charges and may therefore be disadvantageous. 

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

Reinstatement Privilege (Class A Shares Only) 

   If you redeem all or part of your Class A shares of the Fund, you may 
reinvest all or part of the redemption proceeds without a sales commission 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 shares of the Fund 
after receipt of the written request for reinstatement. You may realize a 
gain or loss for federal income tax purposes as a result of the redemption, 
and special tax rules may apply if a reinvestment occurs. Subject to the 
provisions outlined under "How to Exchange Fund Shares" above, you may also 
reinvest in certain other Pioneer mutual funds; in this case you must meet 
the minimum investment requirement for each fund you enter. The 90-day 
reinvestment period may be extended by PFD for periods of up to one year for 
shareholders living in areas that have experienced a natural disaster, such 
as a flood, hurricane, tornado or earthquake. 

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

XIII. THE FUND 

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

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

XIV. INVESTMENT RESULTS 

   
   The average annual total return (for a designated period of time) on an 
investment in the Fund may be included in advertisements, and furnished to 
existing or prospective shareholders. The average annual total return for 
each Class is computed in accordance with the SEC's standardized formula. The 
calculation for all Classes assumes the reinvestment of all dividends and 
distributions at net asset value and does not reflect the impact of federal 
or state income taxes. In addition, for Class A shares the calculation 
assumes the deduction of the maximum sales charge of 4.50%; for Class B 
shares the calculation reflects the deduction of any applicable CDSC. The 
periods illustrated would normally include one, five and ten years (or since 
the commencement of the public offering of the shares of a Class, if shorter) 
through the most recent calendar quarter. 
    

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

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

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

1.       INVESTMENT POLICIES AND RESTRICTIONS

   
         The  Prospectus  (the  "Prospectus")  of Pioneer Bond Fund (the "Fund")
identifies the investment  objectives and the principal  investment  policies of
the Fund. Other investment policies of the Fund are set forth below.
    

Lending of Portfolio Securities

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

         As with other extensions of credit there are risks of delay in recovery
or even loss of rights in the  collateral  should the borrower of the securities
fail  financially.  The Fund will lend portfolio  securities only to firms which
have been  approved  in  advance  by the Fund's  Board of  Trustees,  which will
monitor the  creditworthiness  of any such firms.  At no time would the value of
the  securities  loaned exceed 30% of the value of the Fund's total assets.  The
Fund did not lend  portfolio  securities  during the last fiscal year and has no
present intention to engage in any material securities lending in the future.

Mortgage-Backed Securities

Multiple-Class Pass-through Securities and Collateralized Mortgage Obligations

   
         The Fund may invest in collateralized mortgage obligations ("CMOs") and
real estate mortgage investment conduit ("REMIC")  pass-through or participation
certificates, which may be issued by, among others, U.S. Government agencies and
instrumentalities  as well as private lenders.  CMOs and REMIC  certificates are
issued in multiple  classes and the  principal  of and  interest on the mortgage
assets may be allocated among the several classes of CMOs or REMIC  certificates
in various ways. Each class of CMOs or REMIC certificates,  often referred to as
a "tranche," is issued at a specific  adjustable or fixed interest rate and must
be fully retired no later than its final distribution date. Generally,  interest
is paid or accrues on all  classes  of CMOs or REMIC  certificates  on a monthly
    

                                      B-2
<PAGE>

basis.  Typically,  CMOs are  collateralized  by  certificates of the Government
National Mortgage Association, the Federal National Mortgage Association, or the
Federal Home Loan Mortgage  Corporation but also may be  collateralized by other
mortgage assets such as whole loans or private mortgage pass-through securities.
Debt  service on CMOs is provided  from  payments of  principal  and interest on
collateral of mortgaged assets and any reinvestment income thereon.

Risk Factors Associated with Mortgaged-Backed Securities

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

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


Investment Restrictions

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


                                      B-3
<PAGE>

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

         The Fund may not:

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

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

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

                  (4)  underwrite any issue of securities;

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

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

                                      B-4
<PAGE>

                  (7)  purchase securities on margin;

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

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

         Non-fundamental Investment Restrictions The following restrictions have
been  designated as  non-fundamental  and may be changed by a vote of the Fund's
Board of Trustees without approval of shareholders.

         The Fund may not:

                  (1) invest in companies for the purpose of exercising  control
or management;

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

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

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

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

         It is the  policy of the Fund not to  concentrate  its  investments  in
securities of companies in any particular  industry or group of  industries.  In
the opinion of the staff of the Securities and Exchange  Commission (the "SEC"),
investments  are  concentrated  in a  particular  industry  if such  investments
aggregate 25% or more of the Fund's total  assets.  The Fund has agreed to abide
by the  foregoing  non-fundamental  policy which it will not change  without the
affirmative  vote of a majority of the Fund's  outstanding  shares of beneficial
interest.

                                      B-5
<PAGE>

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

Other Policies and Risks

         The Fund may invest up to 15% of its assets in foreign  securities  and
up to 5% of  its  assets  in  foreign  securities  which  are  not  listed  on a
recognized  foreign or domestic  exchange,  provided that  purchases of Canadian
securities are not subject to the  limitations in this  paragraph.  Investing in
securities of foreign  companies and countries  involves certain  considerations
and risks which are not typically  associated with investing in U.S.  government
securities and those of domestic companies.  Foreign companies are not generally
subject to uniform accounting, auditing and financial standards and requirements
comparable  to  those  applicable  to U.S.  companies.  There  may  also be less
government  supervision and regulation of foreign securities exchanges,  brokers
and listed companies than exists in the United States.

         Interest  paid by foreign  issuers  may be subject to  withholding  and
other  foreign  taxes which may decrease the net return on such  investments  as
compared  to  interest  paid to the Fund by the U.S.  government  or by domestic
companies.  In  addition,  there  may  be  the  possibility  of  expropriations,
confiscatory taxation,  political,  economic or social instability or diplomatic
developments  which could affect  assets of the Fund held in foreign  countries.
The value of foreign securities may be adversely affected by fluctuations in the
relative rates of exchange  between the  currencies of different  nations and by
exchange control regulations.  There may be less publicly available  information
about  foreign  companies  and  governments  compared  to  reports  and  ratings
published about U.S.  companies.  Foreign  securities markets have substantially
less volume than domestic  markets and securities of some foreign  companies are
less liquid and more volatile than securities of comparable U.S.
companies.

2.       MANAGEMENT OF THE FUND

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

       contracts of various insurance companies or for certain qualified pension
       plans.

         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 as of September 30, 1995,
except  Mr.  Cogan  who then  owned  approximately  15% of such  shares.  To the
knowledge of the  management of the Fund, no person or entity owned more than 5%
of the  outstanding  Class A shares of the Fund as of September  30, 1995. As of
September  30,  1995,  the only  person or entity that owned more than 5% of the

(58,962 shares) of the Fund's outstanding Class B shares.
    

Compensation of Officers and Trustees

   
         The Fund pays no salaries or compensation  to any of its officers.  The
Fund pays an annual trustees' fee of $1,000, and a payment of $100 plus expenses
per meeting attended, to each Trustee who is not affiliated with PMC, PFD or PSC
and  pays  an  annual  trustees'  fee of $500  plus  expenses  to  each  Trustee
affiliated  with PMC, PFD or PSC. Any such fees and expenses  paid to affiliates
or  interested  persons of PMC, PFD or PSC are  reimbursed to the Fund under its
management contract.  As of September 30, 1995, the Trustees and officers of the
Fund owned, in the aggregate,  less than 1% of the outstanding securities of the
Fund.

3.       INVESTMENT ADVISER

         The  Fund  has   contracted   with  PMC,  60  State   Street,   Boston,
Massachusetts, to act as its investment adviser. The term of the contract is one
year, but it is renewable  annually after such date by the vote of a majority of
the Board of Trustees of the Fund (including a majority of the Board of Trustees
who are not parties to the contract or  interested  persons of any such parties)
cast in person at a meeting  called for the  purpose of voting on such  renewal.
This contract  terminates if assigned and may be terminated  without  penalty by
either  party by vote of its  Board of  Directors  or  Trustees  or by vote of a
majority of outstanding  voting securities and the giving of sixty days' written
notice.  Pursuant  to the  management  contract,  PMC will not be liable for any
error of judgment or mistake of law or for any loss  sustained  by reason of the
adoption of any  investment  policy or the  purchase,  sale or  retention of any
securities on the recommendation of PMC. PMC, however,  is not protected against
liability by reason of wilful misfeasance,  bad faith or gross negligence in the
performance  of its  duties  or by  reason  of  its  reckless  disregard  of its
obligations and duties under the respective management contract.

                                      B-11
<PAGE>

   
         As compensation for its management services and expenses incurred,  PMC
is  entitled  to a  management  fee at the rate of 0.50% per annum of the Fund's
average daily net assets.  The fee is normally  computed daily and paid monthly.
During  its  1995,  1994 and 1993  fiscal  years,  the Fund  paid or owed  total
management  fees  to PMC  of  approximately  $546,000,  $571,000  and  $536,000,
respectively.
    

4.       UNDERWRITING AGREEMENT AND DISTRIBUTION PLANS

         The Fund has  entered  into an  Underwriting  Agreement  with PFD.  The
Underwriting  Agreement will continue from year to year if annually  approved by
the  Trustees.  The  Underwriting  Agreement  provides  that PFD  will  bear any
distribution expenses not borne by the Fund.

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

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

         Class A Plan

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

                                      B-12
<PAGE>

         Class B Plan

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

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

         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.

                                      B-13
<PAGE>

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

         The Plans were  adopted by a  majority  vote of the Board of  Trustees,
including  all of the Trustees who are not, and were not at the time they voted,
interested  persons of the Fund, as defined in the 1940 Act (none of whom had or
have any direct or indirect  financial  interest in the operation of the Plans),
cast in person at a meeting  called for the  purpose of voting on the Plans.  In
approving  the  Plans,  the  Trustees  identified  and  considered  a number  of
potential  benefits which the Plans may provide.  The Board of Trustees believes
that there is a reasonable  likelihood  that the Plans will benefit the Fund and
its current and future  shareholders.  Under their  terms,  the Plans  remain in
effect from year to year provided such continuance is approved  annually by vote
of the Trustees in the manner  described  above. The Plans may not be amended to
increase materially the annual percentage limitation of average net assets which
may be  spent  for  the  services  described  therein  without  approval  of the
shareholders of the Fund affected thereby,  and material amendments of the Plans
must also be approved by the Trustees in the manner  described above. A Plan may
be  terminated  at any time,  without  payment  of any  penalty,  by vote of the
majority of the Trustees who are not interested  persons of the Fund and have no
direct or indirect  financial  interest in the  operations  of the Plan, or by a
vote of a majority of the outstanding  voting securities of the respective Class
of the Fund (as defined in the 1940 Act). A Plan will automatically terminate in
the event of its assignment (as defined in the 1940 Act).

   
         During the fiscal year ended June 30,  1995,  the Fund  incurred  total
distribution  fees of $211,000 pursuant to the Class A Plan and $38,000 pursuant
to the  Class  B  Plan.  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.
    

5.       SHAREHOLDER SERVICING/TRANSFER AGENT

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

                                      B-14
<PAGE>

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

   
         PSC  receives  an  annual  fee of $28.00  per each  Class A and Class B
shareholder  account from the Fund as  compensation  for the services  described
above.  This fee is set at an amount  determined  by vote of a  majority  of the
Fund's Trustees (including a majority of the Trustees who are not parties to the
contract with PSC or interested persons of any such parties) to be comparable to
fees for such services being paid by other investment companies.
    

6.       CUSTODIAN

         Brown  Brothers  Harriman & Co.  (the  "Custodian"),  40 Water  Street,
Boston,  Massachusetts  02109,  is the  custodian  of  the  Fund's  assets.  The
Custodian's responsibilities include safekeeping and controlling the Fund's cash
and securities,  handling the receipt and delivery of securities, and collecting
interest  and  dividends  on the  Fund's  investments.  The  Custodian  does not
determine the  investment  policies of the Fund or decide which  securities  the
Fund will buy or sell. The Fund may,  however,  invest in securities,  including
repurchase  agreements,  issued by the Custodian and may deal with the Custodian
as principal in securities  transactions.  Portfolio securities may be deposited
into the Federal Reserve-Treasury Department Book Entry System or the Depository
Trust Company.

7.       PRINCIPAL UNDERWRITER

   
         PFD,  60 State  Street,  Boston,  Massachusetts  02109,  serves  as the
principal underwriter for the Fund. During the Fund's 1995, 1994 and 1993 fiscal
years,  net  underwriting  commissions  earned  by PFD in  connection  with  its
offering  of Fund  shares  were  approximately  $39,000,  $66,000  and  $70,000,
respectively.  Commissions reallowed to dealers by PFD in those three years were
approximately $268,000, $492,000 and $566,000,  respectively.  See "Underwriting
Agreement and  Distribution  Plan" above for a  description  of the terms of the
Underwriting Agreement with PFD.
    

         The Fund will not generally issue Fund shares for  consideration  other
than cash. At the Fund's sole discretion,  however, it may issue Fund shares for
consideration  other than cash in connection  with an  acquisition  of portfolio
securities  (other than  municipal  debt  securities  issued by state  political
subdivisions  or their  agencies or  instrumentalities)  pursuant to a bona fide
purchase of assets,  merger or other reorganization  provided (i) the securities
meet the investment objectives and policies of the Fund; (ii) the securities are


                                      B-15
<PAGE>

acquired by the Fund for investment and not for resale;  (ii) the securities are
not restricted as to transfer either by law or liquidity of market; and (iv) the
securities have a value which is readily ascertainable (and not established only
by  evaluation  procedures)  as  evidenced  by a listing on the  American  Stock
Exchange or the New York Stock Exchange or by quotation under the NASD Automated
Quotation  System. An exchange of securities for Fund shares will generally be a
taxable transaction to the shareholder.

8.       INDEPENDENT PUBLIC ACCOUNTANTS

         Arthur Andersen LLP, One  International  Place,  Boston,  Massachusetts
02110, are the Fund's independent public accountants,  providing audit services,
tax  return  review,  and  assistance  and  consultation  with  respect  to  the
preparation of filings with the SEC.

9.       PORTFOLIO TRANSACTIONS

   
         All orders for the purchase or sale of portfolio  securities are placed
on behalf of the Fund by PMC pursuant to authority  contained in the  management
contract.  Securities  purchased and sold on behalf of the Fund normally will be
traded in the over-the counter market on a net basis (i.e.  without  commission)
through  dealers  acting for their own account  and not as brokers or  otherwise
through transactions directly with the issuer of the instrument. Some securities
are  purchased  and  sold on an  exchange  or in  over-the-counter  transactions
conducted on an agency basis involving a commission.  The primary  consideration
in placing  portfolio  security  transactions is execution at the most favorable
prices. Additionally, in selecting brokers or dealers, PMC will consider various
relevant  factors,  including,  but not  limited  to,  the  size and type of the
transaction;  the nature and  character  of the markets  for the  security to be
purchased  or  sold;  the  execution  efficiency,   settlement  capability,  and
financial condition of the dealer; the dealer's execution services rendered on a
continuing  basis; the  reasonableness  of any dealer spreads;  and the dealer's
sale of shares of the Fund or other Pioneer mutual funds.
    

         PMC may select dealers which provide brokerage and/or research services
to the Fund and/or other investment  companies  managed by PMC.  Consistent with
Section 28(e) of the Securities  Exchange Act of 1934, as amended,  the Fund may
pay  commissions  to such  broker-dealers  in an amount  greater than the amount
another firm might charge as compensation for such services if PMC determines in
good faith  that the amount of the  commissions  charged by a  broker-dealer  is
reasonable  in relation to the  services  provided by such  broker-dealer.  Such
services may include advice concerning the value of securities; the advisability
of  investing  in,  purchasing  or  selling  securities;   the  availability  of
securities or the  purchasers or sellers of  securities;  providing  stock price


                                      B-16
<PAGE>

quotation services; furnishing analyses, manuals and reports concerning issuers,
industries,   securities,  economic  factors  and  trends,  portfolio  strategy,
performance of accounts,  comparative  fund statistics and credit rating service
information;  and effecting  securities  transactions  and performing  functions
incidental  thereto (such as clearance and settlement).  PMC maintains a listing
of broker-dealers who provide such services on a regular basis. However, because
it is  anticipated  that  many  transactions  on  behalf  of the Fund and  other
investment  companies managed by PMC are placed with  broker-dealers  (including
broker-dealers  on the  listing)  without  regard  to  the  furnishing  of  such
services,  it is not possible to estimate the  proportion  of such  transactions
directed to such  broker-dealers  solely  because such services  were  provided.
Management  believes  that no exact  dollar  value  can be  calculated  for such
services.

         The  research  received  from dealers may be useful to PMC in rendering
investment  management  services  to the Fund  and  other  investment  companies
managed by PMC, and conversely,  such information provided by brokers or dealers
who have executed  transaction orders on behalf of such other PMC clients may be
useful to PMC in carrying out its  obligations  to the Fund. The receipt of such
research has not reduced PMC's normal independent research activities;  however,
it  enables  PMC to avoid the  additional  expenses  which  might  otherwise  be
incurred if it were to attempt to develop comparable information through its own
staff.

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

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

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

                                      B-17
<PAGE>

         It is possible  that, at times,  identical  securities  will be held by
more than one fund and/or account.  However, the position of any fund or account
in the same issue may vary and the  length of time that any fund or account  may
choose to hold its investment in the same issue may likewise vary. To the extent
that the Fund,  another  mutual fund in the Pioneer  group or a private  account
managed by PMC seeks to acquire the same  security  at about the same time,  the
Fund may not be able to  acquire  as large a  position  in such  security  as it
desires or it may have to pay a higher price for the  security.  Similarly,  the
Fund may not be able to obtain as large an  execution  of an order to sell or as
high a price for any  particular  portfolio  security  if PMC decides to sell on
behalf of another  account the same portfolio  security at the same time. On the
other hand, if the same  securities  are bought or sold at the same time by more
than one account,  the  resulting  participation  in volume  transactions  could
produce better executions for the Fund or other account.  In the event that more
than one account  purchases  or sells the same  security  on a given  date,  the
purchases and sales will normally be made as nearly as practicable on a pro rata
basis in proportion to the amounts desired to be purchased or sold by each.

10.      TAX STATUS

   
         It is the Fund's policy to meet the requirements of Subchapter M of the
Internal Revenue Code of 1986, as amended (the "Code"),  for  qualification as a
regulated  investment  company.  These requirements relate to the sources of its
income, the diversification of its assets and the timing of its distributions to
shareholders.  If the Fund meets all such  requirements  and  distributes to its
shareholders, in accordance with the Code's timing requirements,  all investment
company taxable income and net capital gain, if any, which it receives, the Fund
will be relieved of the necessity of paying  federal income tax. The Fund is not
subject to Massachusetts  corporate excise or franchise taxes and, provided that
it qualifies as a regulated  investment company for federal income tax purposes,
it will not be required to pay any Massachusetts income tax.
    

         Dividends from investment  company  taxable income,  which includes net
investment  income,  net  short-term  capital  gain in excess  of net  long-term
capital loss, and certain net foreign  exchange  gains,  are taxable as ordinary
income,  whether received in cash or reinvested in additional shares.  Dividends
from net  long-term  capital gain in excess of net  short-term  capital loss, if
any,  whether received in cash or additional  shares,  are taxable to the Fund's
shareholders as long-term  capital gains for federal income tax purposes without
regard to the  length of time  shares of the Fund have been  held.  The  federal
income  tax  status  of all  distributions  will  be  reported  to  shareholders
annually. Because none of the Fund's income is expected to arise from dividends,


                                      B-18
<PAGE>

no part of the distributions to its corporate  shareholders will qualify for the
dividends-received deduction for corporations.

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

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

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

         At the time of an investor's  purchase of Fund shares, a portion of the
purchase price may be attributable to realized or unrealized appreciation in the
Fund's portfolio. Consequently,  subsequent distributions 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.

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

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


                                      B-19
<PAGE>

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

         For Federal income tax purposes, the Fund is permitted to carry forward
a net capital loss in any year to offset capital gains, if any, during the eight
years following the year of the loss. To the extent subsequent capital gains are
offset by such losses,  they would not result in Federal income tax liability to
the Fund and are not expected to be distributed as such to shareholders. At June
30, 1995, the Fund had a net capital loss carryforward of $2,956,000, which will
expire between 1998 and 2003 if not utilized.
    

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

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

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

<PAGE>

   
         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.  Investors  other than U.S.  persons may be
subject  to  different  U.S.  tax  treatment,  including  a  possible  30%  U.S.
withholding  tax (or  withholding tax at a lower treaty rate) on amounts treated
as ordinary  dividends  from the Fund and,  unless an effective  IRS Form W-8 or
authorized  substitute  is on file, to 31% backup  withholding  on certain other
payments from the Fund. The description  above also does not address special tax
rules that may be applicable to certain classes of investors, such as tax-exempt
entities,  insurance companies, and financial institutions.  Shareholders should
consult  their own tax advisors on these  matters and on state,  local and other
applicable tax laws.
    

11.      DESCRIPTION OF SHARES

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

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

         Although  Trustees  are  not  elected  annually  by  the  shareholders,
shareholders  have under certain  circumstances  the right to remove one or more
Trustees.  No amendment that adversely affects the rights of shareholders may be
made to the  Fund's  Declaration  of Trust  without  the  affirmative  vote of a


                                      B-21
<PAGE>

   
majority of its shares.  Shares have no preemptive  or conversion  rights except
that under certain  circumstances  Class B shares may convert to Class A shares.
Shares are fully paid and non-assessable by the Fund, except as set forth below.
See "Certain Liabilities."
    

 12.     CERTAIN LIABILITIES

         As a Massachusetts  business trust, the Fund's  operations are governed
by its  Declaration  of Trust dated December 7, 1993, a copy of which is on file
with the office of the Secretary of State of The Commonwealth of  Massachusetts.
Theoretically, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held  personally  liable  for the  obligations  of the trust.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability  for acts or  obligations  of the Fund or any  series  of the Fund and
provides that notice of such disclaimer be given in each  agreement,  obligation
or instrument  entered into or executed by the Fund or its  Trustees.  Moreover,
the Declaration of Trust provides for the  indemnification  out of Fund property
of any  shareholders  held personally  liable for any obligations of the Fund or
any series of the Fund.  The  Declaration  of Trust also  provides that the Fund
shall,  upon  request,  assume  the  defense  of  any  claim  made  against  any
shareholder  for any act or  obligation  of the Fund and  satisfy  any  judgment
thereon.  Thus, the risk of a shareholder incurring financial loss beyond his or
her   investment   because  of  shareholder   liability   would  be  limited  to
circumstances  in which the Fund itself will be unable to meet its  obligations.
In light of the nature of the Fund's  business  and the nature and amount of its
assets,  the  possibility of the Fund's  liabilities  exceeding its assets,  and
therefore a shareholder's risk of personal liability, is remote.

         The Declaration of Trust further provides that the Fund shall indemnify
each of its Trustees and officers  against  liabilities and expenses  reasonably
incurred by them,  in connection  with,  or arising out of, any action,  suit or
proceeding,  threatened against or otherwise  involving such Trustee or officer,
directly or  indirectly,  by reason of being or having been a Trustee or officer
of the Fund.  The  Declaration of Trust does not authorize the Fund to indemnify
any Trustee or officer  against any liability to which he or she would otherwise
be subject by reason of or for willful misfeasance,  bad faith, gross negligence
or reckless disregard of such person's duties.

13.      DETERMINATION OF NET ASSET VALUE

         The net asset  value per share of each class of the Fund is  determined
as of the close of regular trading on the Exchange (currently 4:00 p.m., Eastern
Time) on each day on which the Exchange is open for  trading.  As of the date of
this Statement of Additional Information, the Exchange is open for trading every
weekday except for the following holidays: New Year's Day, Presidents' Day, Good
Friday,  Memorial  Day,  Independence  Day,  Labor  Day,  Thanksgiving  Day  and


                                      B-22
<PAGE>

Christmas  Day.  The net asset value per share of each class of the Fund is also
determined  on any  other day in which the  level of  trading  in its  portfolio
securities  is  sufficiently  high so that the current net asset value per share
might  be  materially  affected  by  changes  in  the  value  of  its  portfolio
securities.  On any day in which no  purchase  orders for the shares of the Fund
become effective and no shares are tendered for redemption,  the net asset value
per share is not required to be determined.

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

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

14.      SYSTEMATIC WITHDRAWAL PLAN

         The  Systematic  Withdrawal  Plan  ("SWP")  is  designed  to  provide a
convenient  method of receiving fixed payments at regular  intervals from shares
of the Fund  deposited  by the  applicant  under this SWP.  The  applicant  must
deposit or purchase for deposit with PSC shares of the Fund having a total value
of not less than $10,000. Withdrawals from Class B share accounts are limited to
10% of the value of the  account  at the time the SWP is  implemented.  Periodic
checks of $50 or more will be sent to the applicant, or any person designated by
him, monthly or quarterly.

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

                                      B-23
<PAGE>

         SWP  payments are made from the  proceeds of the  redemption  of shares
deposited  under the SWP in a SWP account.  To the extent that such  redemptions
for periodic  withdrawals  exceed dividend income reinvested in the SWP account,
such  redemptions  will reduce and may  ultimately  exhaust the number of shares
deposited in the Plan account.  Share redemptions are taxable transactions,  and
in addition the amounts  received by a  shareholder  cannot be  considered as an
actual yield or income on his or her  investment  because part of such  payments
may be a return of his or her investment.

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

15.      LETTER OF INTENTION

   
         Purchases  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 by PFD will qualify
for a reduced  sales  charge.  Such reduced sales charge will be the charge that
would be applicable to the purchase of all Class A shares  purchased during such
13-month period pursuant to a Letter of Intention had such shares been purchased
all at once.  See "How to Buy Fund Shares" in the  Prospectus.  For  example,  a
person who signs a Letter of Intention  providing for a total investment in Fund
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  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 shares of record held in the Fund and other  Pioneer  mutual funds
as of the date of the Letter of Intention  as a credit  toward  determining  the
applicable  scale of sales charge for the Class A shares to be  purchased  under
the Letter of Intention.
    

         The  Letter  of  Intention  authorizes  PSC to escrow  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 read the
provisions  of the Letter of  Intention  contained  in the  Account  Application
carefully before signing.

16.      INVESTMENT RESULTS

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

Quotations, Comparisons, and General Information

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

         In addition, the performance of the classes of the Fund may be compared
to alternative investment or savings vehicles and/or to indices or indicators of
economic activity,  e.g., inflation or interest rates.  Performance rankings and

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


                                      B-25
<PAGE>

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

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

Standardized Yield Quotations

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

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

Where:            a   =    interest earned during the period

                  b   =    net expenses accrued for the period

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

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

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

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


                                      B-26
<PAGE>

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.

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

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

   
           The Fund's  yield for the 30 days ended June 30,  1995,  computed  as
above was 5.80% for Class A shares and 5.29% for Class B shares.
    

Standardized Average Annual Total Return Quotations

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

                                      B-27
<PAGE>

                           P(1+T)n  =   ERV

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

           T     =     average annual total return

           n     =     number of years

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

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

           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 average  annual total  returns for Class A shares of the Fund for
the one-year,  five-year and ten-year  periods  ending June 30, 1995 were 6.42%,
8.08% and 8.44%,  respectively.  The average  annual  total  returns for Class B
shares of the Fund for the one-year  and  life-of-class  periods  (April 4, 1994
inception) ended June 30, 1995 were 6.57% and 4.62%, respectively.

                                   APPENDIX A

                          Description of Bond Ratings1

                        Moody's Investor's Service, Inc.2

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

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

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

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

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

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

                                      B-30
<PAGE>

           THE FUND IS NOT  PERMITTED  TO  INVEST  IN DEBT  SECURITIES  WITH THE
FOLLOWING  MOODY'S  RATINGS;  THIS INFORMATION IS PROVIDED IN THE UNLIKELY EVENT
THAT THE FUND WOULD RETAIN A DEBT  SECURITY  THAT HAD BEEN  DOWNGRADED TO ONE OF
THESE LOWER RATINGS.

           Ba: Bonds which are rated Ba are judged to have speculative elements;
their future  cannot be  considered  as well  assured.  Often the  protection of
interest  and  principal  payments  may be very  moderate  and  thereby not well
safeguarded  during  both good and bad times  over the  future.  Uncertainty  of
position characterizes bonds in this class.

           B: Bonds  which are rated B  generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interest  and  principal  payments  or of
maintenance  of other terms of the contract  over any long period of time may be
small.

           Caa: Bonds which are rated Caa are of poor standing.  Such issues may
be in  default  or there may be  present  elements  of danger  with  respect  to
principal or interest.

           Ca:  Bonds  which  are  rated  Ca  represent  obligations  which  are
speculative  in a high  degree.  Such  issues are often in default or have other
marked shortcomings.

           C:  Bonds  which are rated C are the lowest  rated  class of bonds an
issues so rated can be  regarded  as having  extremely  poor  prospects  of ever
attaining any real investment standing.

                        Standard & Poor's Ratings Group 3

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

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

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


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

                                      B-31
<PAGE>

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

           THE FUND IS NOT  PERMITTED  TO  INVEST  IN DEBT  SECURITIES  WITH THE
FOLLOWING  STANDARD  & POOR'S  RATINGS;  THIS  INFORMATION  IS  PROVIDED  IN THE
UNLIKELY  EVENT  THAT  THE  FUND  WOULD  RETAIN  A DEBT  SECURITY  THAT HAD BEEN
DOWNGRADED TO ONE OF THESE LOWER RATINGS.

           BB: Debt rated BB has less  near-term  vulnerability  to default than
other  speculative  issues.  However,  it faces major ongoing  uncertainties  or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate  capacity to meet timely interest and principal  payments.  The BB
rating  category  is also  used for debt  subordinated  to  senior  debt that is
assigned an actual or implied BBB - rating.

           B: Debt rated B has greater  vulnerability  to default but  currently
has the capacity to meet  interest  payments and principal  repayments.  Adverse
business,  financial,  or economic  conditions  will likely  impair  capacity or
willingness to pay interest and repay principal.

           CCC:  Debt rated CCC has a currently  identifiable  vulnerability  to
default,  and is dependent  upon  favorable  business,  financial,  and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse business,  financial, or economic conditions,  it is not likely
to have the capacity to pay interest and repay principal.

           CC: The rating CC is typically applied to debt subordinated to senior
debt which is assigned an actual or implied CCC debt rating.

           C: The rating C is typically  applied to debt  subordinated to senior
debt which is assigned an actual or implied CCC - debt rating.  The C rating may
be used to cover a situation  where a bankruptcy  petition  has been filed,  but
debt service payments are continued.

           C1: The Rating C1 is reserved  for income  bonds on which no interest
is being paid.

           D: Debt rated D is in payment default.  The D rating category is used
when interest  payments or principal  payments are not made on the date due even
if the  applicable  grace  period  has not  expired,  unless  Standard  & Poor's
believes that such payments will be made during such grace period.  The D rating
also  will be used upon the  filing of a  bankruptcy  petition  if debt  service
payments are jeopardized.

                                   APPENDIX B
                               INDEX DESCRIPTIONS


LONG-TERM CORPORATE BONDS *
For 1969 through  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.
For 1926 through  1968,  total  returns were  calculated  by summing the capital
appreciation  returns and the income returns.  For the period 1946 through 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.

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

INTERMEDIATE-TERM GOVERNMENT BONDS TOTAL RETURN *
Total  returns  of the  intermediate-term  government  bonds for  1977-1991  are
calculated from The Wall Street Journal prices,  using the change in flat price.
Returns for 1934 through 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.) For the period from 1934 through
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.  Between 1926 and 1933,  there are few bonds
suitable for construction of a series with a 5-year maturity.
For this period, five year bond yield estimates are used.

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

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

          Information included in the Registration  Statement of the Trust under

                                   ARTICLE II

                                    TRUSTEES

         Section 2.1.  General  Powers.  The Trustees  shall have  exclusive and
absolute  control over the Trust  Property and over the business of the Trust to
the same extent as if the  Trustees  were the sole owners of the Trust  Property
and business in their own right,  but with such powers of  delegation  as may be
permitted  by this  Declaration.  The  Trustees  shall have power to conduct the
business of the Trust and carry on its operations in any and all of its branches
and maintain offices both within and without the Commonwealth of  Massachusetts,
in any and all  states of the  United  States of  America,  in the  District  of
Columbia, and in any and all commonwealths, territories, dependencies, colonies,
possessions,  agencies or  instrumentalities of the United States of America and
of foreign  governments,  and to do all such other  things and  execute all such
instruments as they deem necessary,  proper or desirable in order to promote the
interests  of the  Trust  although  such  things  are  not  herein  specifically
mentioned. Any determination as to what is in the interests of the Trust made by
the Trustees in good faith shall be conclusive.  In construing the provisions of
this  Declaration,  the presumption shall be in favor of a grant of power to the
Trustees.

         The  enumeration of any specific power herein shall not be construed as
limiting  the  aforesaid  powers.  Such powers of the  Trustees may be exercised
without order of or resort to any court.

         Section 2.2. Investments. The Trustees shall have the power:

                  (a) To operate as and carry on the  business of an  investment
         company,  and exercise all the powers  necessary and appropriate to the
         conduct of such operations.

                  (b) To invest in, hold for  investment,  or reinvest in, cash;
         securities,   including  common,   preferred  and  preference   stocks;
         warrants;    subscription   rights;    profit-sharing    interests   or
         participations  and all  other  contracts  for or  evidence  of  equity
         interests; bonds, debentures, bills, time notes and all other evidences
         of indebtedness;  negotiable or non-negotiable instruments;  government
<PAGE>

         securities,  including  securities of any state,  municipality or other
         political    subdivision    thereof,    or    any    governmental    or
         quasi-governmental   agency  or   instrumentality;   and  money  market
         instruments  including  bank  certificates  of deposit,  finance paper,
         commercial  paper,  bankers'  acceptances  and all kinds of  repurchase
         agreements, of any corporation,  company, trust,  association,  firm or
         other business  organization however  established,  and of any country,
         state, municipality or other political subdivision, or any governmental
         or quasi-governmental agency or instrumentality; and the Trustees shall
         be deemed to have the foregoing  powers with respect to any  additional
         securities  in which  the  Trust  may  invest  should  the  Fundamental
         Restrictions be amended.

                  (c) To acquire (by purchase,  subscription  or otherwise),  to
         hold,  to trade in and deal in, to  acquire  any  rights or  options to
         purchase  or sell,  to sell or  otherwise  dispose  of,  to lend and to
         pledge  any such  securities,  to  enter  into  repurchase  agreements,
         reverse repurchase  agreements,  firm commitment agreements and forward
         foreign currency  exchange  contracts,  to purchase and sell options on
         securities,  securities  indices,  currency and other financial assets,
         futures  contracts and options on futures contracts of all descriptions
         and to engage in all types of hedging and risk-management transactions.

                  (d) To exercise all rights, powers and privileges of ownership
         or interest in all securities and repurchase agreements included in the
         Trust  Property,  including the right to vote thereon and otherwise act
         with  respect  thereto  and  to  do  all  acts  for  the  preservation,
         protection, improvement and enhancement in value of all such securities
         and repurchase agreements.

                  (e) To acquire (by purchase,  lease or otherwise) and to hold,
         use,  maintain,  develop  and  dispose  of (by sale or  otherwise)  any
         property, real or personal, including cash or foreign currency, and any
         interest therein.

                  (f) To borrow  money  and in this  connection  issue  notes or
         other  evidence of  indebtedness;  to secure  borrowings by mortgaging,
         pledging or otherwise subjecting as security the Trust Property; and to
         endorse,  guarantee,  or undertake the performance of any obligation or
         engagement of any other Person and to lend Trust Property.

                  (g) To aid by further  investment  any  corporation,  company,
         trust,  association  or firm, any obligation of or interest in which is
         included in the Trust  Property or in the affairs of which the Trustees
         have any  direct  or  indirect  interest;  to do all  acts  and  things
<PAGE>

         designed  to  protect,  preserve,  improve or enhance the value of such
         obligation or interest; and to guarantee or become surety on any or all
         of  the  contracts,   stocks,   bonds,  notes,   debentures  and  other
         obligations of any such  corporation,  company,  trust,  association or
         firm.

                  (h) To  enter  into a plan of  distribution  and  any  related
         agreements  whereby the Trust may finance  directly or  indirectly  any
         activity which is primarily intended to result in sales of Shares.

                  (i) To adopt on behalf of the Trust or any  Series  thereof an
         alternative  purchase  plan  providing  for the  issuance  of  multiple
         Classes of Shares (as authorized  herein at Section 5.11),  such Shares
         being  differentiated on the basis of purchase method and allocation of
         distribution expenses.

                  (j) In general to carry on any other  business  in  connection
         with or  incidental to any of the  foregoing  powers,  to do everything
         necessary,  suitable or proper for the accomplishment of any purpose or
         the  attainment  of  any  object  or  the   furtherance  of  any  power
         hereinbefore set forth, either alone or in association with others, and
         to do every other act or thing  incidental or appurtenant to or arising
         out of or connected with the aforesaid business or purposes, objects or
         powers.

         The foregoing  clauses  shall be construed  both as objects and powers,
and the foregoing  enumeration of specific  powers shall not be held to limit or
restrict in any manner the general powers of the Trustees.

         The Trustees shall not be limited to investing in obligations  maturing
before the possible  termination of the Trust, nor shall the Trustees be limited
by any law limiting the investments which may be made by fiduciaries.

         Section 2.3.  Legal Title.  Legal title to all the Trust Property shall
be vested in the Trustees as joint tenants  except that the Trustees  shall have
power to cause legal title to any Trust Property to be held by or in the name of
one or more of the  Trustees,  or in the name of the Trust or any  Series of the
Trust,  or in the name of any other  Person  as  nominee,  on such  terms as the
Trustees  may  determine,  provided  that the  interest of the Trust  therein is
deemed appropriately protected. The right, title and interest of the Trustees in
the Trust  Property  and the  Property  of each  Series of the Trust  shall vest
automatically  in each  Person  who may  hereafter  become a  Trustee.  Upon the
<PAGE>

termination of the term of office, resignation, removal or death of a Trustee he
shall  automatically  cease to have any right,  title or  interest in any of the
Trust Property,  and the right,  title and interest of such Trustee in the Trust
Property shall vest  automatically in the remaining  Trustees.  Such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered.

         Section 2.4. Issuance and Repurchase of Shares. The Trustees shall have
the power to issue, sell, repurchase,  redeem,  retire,  cancel,  acquire, hold,
resell, reissue, dispose of, transfer, and otherwise deal in Shares and, subject
to the provisions  set forth in Articles VI and VII and Section 5.11 hereof,  to
apply  to  any  such  repurchase,   redemption,   retirement,   cancellation  or
acquisition  of Shares any funds or  property of the Trust,  whether  capital or
surplus or otherwise,  to the full extent now or hereafter permitted by the laws
of The Commonwealth of Massachusetts governing business corporations.

         Section 2.5. Delegation; Committees. The Trustees shall have the power,
consistent with their continuing  exclusive authority over the management of the
Trust and the Trust  Property,  to  delegate  from time to time to such of their
number or to officers, employees or agents of the Trust the doing of such things
and the  execution  of such  instruments  either in the name of the Trust or any
Series of the Trust or the names of the  Trustees or  otherwise  as the Trustees
may deem  expedient,  to the same extent as such  delegation is permitted by the
1940 Act.

         Section 2.6.  Collection  and Payment.  Subject to Section 5.11 hereof,
the Trustees  shall have the power to collect all property due to the Trust;  to
pay all claims,  including  taxes,  against the Trust  Property;  to  prosecute,
defend,  compromise  or abandon any claims  relating to the Trust  Property;  to
foreclose any security interest securing any obligations, by virtue of which any
property is owed to the Trust; and to enter into releases,  agreements and other
instruments.

         Section 2.7.  Expenses.  Subject to Section  5.11 hereof,  the Trustees
shall have the power to incur and pay any  expenses  which in the opinion of the
Trustees are  necessary or  incidental  to carry out any of the purposes of this
Declaration,  and to pay reasonable  compensation from the funds of the Trust to
themselves as Trustees. The Trustees shall fix the compensation of all officers,
employees and Trustees of the Trust.

         Section 2.8. Manner of Acting;  By-laws.  Except as otherwise  provided
herein or in the By-laws, any action to be taken by the Trustees may be taken by
a majority of the  Trustees  present at a meeting of  Trustees  (a quorum  being
present),  including any meeting held by means of a conference telephone circuit
<PAGE>

or similar communications  equipment by means of which all persons participating
in the meeting can hear each other, or by written  consents of a majority of the
entire  number of Trustees  then in office.  The Trustees may adopt  By-laws not
inconsistent with this Declaration to provide for the conduct of the business of
the Trust and may amend or repeal  such  By-laws to the extent such power is not
reserved to the Shareholders.

         Notwithstanding  the  foregoing  provisions  of this Section 2.8 and in
addition to such provisions or any other provision of this Declaration or of the
By-laws,  the Trustees may by resolution appoint a committee  consisting of less
than the  whole  number of  Trustees  then in  office,  which  committee  may be
empowered to act for and bind the Trustees and the Trust, as if the acts of such
committee were the acts of all the Trustees then in office,  with respect to the
institution,  prosecution, dismissal, settlement, review or investigation of any
action,  suit or  proceeding  which shall be pending or threatened to be brought
before any court, administrative agency or other adjudicatory body.

         Section 2.9.  Miscellaneous Powers. Subject to Section 5.11 hereof, the
Trustees  shall have the power to: (a) employ or contract  with such  Persons as
the Trustees may deem desirable for the transaction of the business of the Trust
or any Series thereof; (b) enter into joint ventures, partnerships and any other
combinations or associations; (c) remove Trustees or fill vacancies in or add to
their  number,  elect and remove such  officers and appoint and  terminate  such
agents or employees  as they  consider  appropriate,  and appoint from their own
number, and terminate, any one or more committees which may exercise some or all
of the power and  authority of the Trustees as the Trustees may  determine;  (d)
purchase, and pay for out of Trust Property or Trust Property of the appropriate
Series of the Trust,  insurance  policies insuring the  Shareholders,  Trustees,
officers, employees, agents, investment advisers, administrators,  distributors,
selected  dealers or  independent  contractors  of the Trust  against all claims
arising by reason of holding any such  position or by reason of any action taken
or  omitted by any such  Person in such  capacity,  whether or not  constituting
negligence,  or whether or not the Trust would have the power to indemnify  such
Person  against such  liability;  (e) establish  pension,  profitsharing,  share
purchase,  and other  retirement,  incentive and benefit plans for any Trustees,
officers, employees and agents of the Trust; (f) to the extent permitted by law,
indemnify  any person with whom the Trust or any Series  thereof  has  dealings,
including the Investment Adviser, Administrator, Distributor, Transfer Agent and
selected dealers, to such extent as the Trustees shall determine;  (g) guarantee
indebtedness or contractual  obligations of others; (h) determine and change the
fiscal  year of the Trust or any Series  thereof  and the method by which its or
<PAGE>

their accounts shall be kept; (i) adopt a seal for the Trust, but the absence of
such seal shall not impair the validity of any instrument  executed on behalf of
the Trust;  and (j) establish record dates relating to meetings of shareholders,
payments of dividends or other distributions, exchanges or conversions of shares
or any other matter deemed appropriate by the Trustees.

         Section  2.10.  Principal  Transactions.  Except  in  transactions  not
permitted by the 1940 Act or rules and  regulations  adopted by the  Commission,
the Trustees may, on behalf of the Trust,  buy any  securities  from or sell any
securities  to, or lend any  assets of the Trust or any  Series  thereof  to any
Trustee or officer of the Trust or any firm of which any such Trustee or officer
is a member acting as principal,  or have any such dealings with the  Investment
Adviser,  Distributor or Transfer  Agent or with any  Interested  Person of such
Person; and the Trust or a Series thereof may employ any such Person, or firm or
company in which such Person is an Interested Person, as broker,  legal counsel,
registrar, transfer agent, dividend disbursing agent or custodian upon customary
terms.

         Section 2.11.  Litigation.  The Trustees shall have the power to engage
in and to prosecute,  defend, compromise,  abandon, or adjust by arbitration, or
otherwise,  any  actions,  suits,  proceedings,  disputes,  claims  and  demands
relating to the Trust,  and out of the assets of the Trust or any Series thereof
to pay or to satisfy  any  debts,  claims or  expenses  incurred  in  connection
therewith,  including those of litigation,  and such power shall include without
limitation the power of the Trustees or any appropriate  committee  thereof,  in
the  exercise  of their or its good faith  business  judgment,  to  dismiss  any
action, suit,  proceeding,  dispute,  claim or demand,  derivative or otherwise,
brought by any person,  including a  Shareholder  in its own name or the name of
the  Trust,  whether  or not  the  Trust  or any of the  Trustees  may be  named
individually  therein or the subject  matter arises by reason of business for or
on behalf of the Trust.

         Section 2.12. Number of Trustees.  The number of Trustees shall be such
number as shall be fixed from time to time by a written  instrument  signed by a
majority of the Trustees,  provided,  however, that the number of Trustees shall
in no event be less than three (3) nor more than fifteen (15).

         Section 2.13.  Election and Torn.  Except for the Trustees named herein
or appointed to fill vacancies pursuant to Section 2.15 hereof, the Trustees may
succeed  themselves and shall be elected by the Shareholders  owning of record a
plurality of the Shares voting at a meeting of  Shareholders  on a date fixed by
the  Trustees.  Except in the event of  resignations  or  removals  pursuant  to
<PAGE>

Section 2.14 hereof, each Trustee shall hold office until such time as less than
a majority of the Trustees holding office have been elected by Shareholders.  In
such event the Trustees  then in office shall call a  Shareholders'  meeting for
the election of Trustees.  Except for the foregoing circumstances,  the Trustees
shall continue to hold office and may appoint successor Trustees.

         Section 2.14. Resignation and Removal. Any Trustee may resign his trust
(without the need for any prior or  subsequent  accounting)  by an instrument in
writing signed by him and delivered to the other  Trustees and such  resignation
shall be effective upon such delivery, or at a later date according to the terms
of the  instrument.  Any of the Trustees may be removed  (provided the aggregate
number of Trustees  after such removal  shall not be less than three) for cause,
by the  action  of  two-thirds  of the  remaining  Trustees  or by action of the
holders of  two-thirds of the  outstanding  Shares of the Trust (for purposes of
determining the circumstances and procedures under which any such removal by the
Shareholders may take place, the provisions of Section 16(c) of the 1940 Act (or
any successor provisions) shall be applicable to the same extent as if the Trust
were subject to the provisions of that Section). Upon the resignation or removal
of a Trustee,  or his  otherwise  ceasing to be a Trustee,  he shall execute and
deliver such  documents as the remaining  Trustees shall require for the purpose
of  memorializing  the conveyance to the Trust or the remaining  Trustees of any
Trust  Property held in the name of the resigning or removed  Trustee.  Upon the
incapacity or death of any Trustee,  his legal  representative shall execute and
deliver on his behalf such documents as the remaining  Trustees shall require as
provided in the preceding sentence.

         Section  2.15.  Vacancies.  The  term  of  office  of a  Trustee  shall
terminate  and a  vacancy  shall  occur in the event of his  death,  retirement,
resignation,  removal, bankruptcy,  adjudicated incompetence or other incapacity
to perform the duties of the office of a Trustee.  No such vacancy shall operate
to annul the  Declaration or to revoke any existing  agency created  pursuant to
the terms of the Declaration.  In the case of an existing  vacancy,  including a
vacancy existing by reason of an increase in the number of Trustees,  subject to
the  provisions of Section 16(a) of the 1940 Act, the remaining  Trustees  shall
fill such  vacancy  by the  appointment  of such  other  person as they in their
discretion shall see fit, made by a written  instrument  signed by a majority of
the Trustees then in office.  Any such appointment  shall not become  effective,
however,  until the person named in the written  instrument of appointment shall
have accepted in writing such  appointment  and agreed in writing to be bound by
the  terms  of the  Declaration.  An  appointment  of a  Trustee  may be made in
<PAGE>

anticipation  of a vacancy  to occur at a later  date by  reason of  retirement,
resignation  or  increase  in  the  number  of  Trustees,   provided  that  such
appointment shall not become effective prior to such retirement,  resignation or
increase in the number of Trustees. Whenever a vacancy in the number of Trustees
shall occur,  until such vacancy is filled as provided in this Section 2.15, the
Trustees  in  office,  regardless  of their  number,  shall  have all the powers
granted to the  Trustees  and shall  discharge  all the duties  imposed upon the
Trustees by the Declaration.  A written  instrument  certifying the existence of
such vacancy  signed by a majority of the Trustees in office shall be conclusive
evidence of the existence of such vacancy.

         Section 2.16.  Delegation of Power to Other Trustees.  Any Trustee may,
by power of  attorney,  delegate  his power for a period not  exceeding  six (6)
months at any one time to any other  Trustee or  Trustees;  provided  that in no
case shall fewer than three (3) Trustees  personally exercise the powers granted
to the Trustees  under this  Declaration  except as herein  otherwise  expressly
provided.

                                  ARTICLE III

                                   CONTRACTS

         Section  3.1.  Underwriting   Contract.   The  Trustees  may  in  their
discretion  from  time  to  time  enter  into  an  exclusive  or   non-exclusive
distribution  contract or contracts  providing for the sale of the Shares to net
the  Trust or the  applicable  Series  of the  Trust  not less  than the  amount
provided  for in Section  7.1 of Article VII hereof,  whereby the  Trustees  may
either  agree to sell the Shares to the other  party to the  contract or appoint
such other party as their sales agent for the Shares, and in either case on such
terms and  conditions,  if any, as may be  prescribed  in the By-laws,  and such
further terms and conditions as the Trustees may in their  discretion  determine
not inconsistent with the provisions of this Article III or of the By-laws;  and
such  contract may also provide for the  repurchase  of the Shares by such other
party as agent of the Trustees.

         Section 3.2. Advisory or Management Contract.  Subject to approval by a
vote of a majority of Shares  outstanding and entitled to vote, the Trustees may
in their discretion from time to time enter into one or more investment advisory
or management contracts or, if the Trustees establish multiple Series,  separate
investment  advisory or management  contracts with respect to one or more Series
whereby  the other party or parties to any such  contracts  shall  undertake  to
furnish   the   Trust   or  such   Series   management,   investment   advisory,
administration,  accounting,  legal,  statistical  and research  facilities  and
services,  promotional or marketing  activities,  and such other  facilities and
<PAGE>

services, if any, as the Trustees shall from time to time consider desirable and
all upon such  terms and  conditions  as the  Trustees  may in their  discretion
determine.  Notwithstanding any provisions of the Declaration,  the Trustees may
authorize the  Investment  Advisers,  or any of them,  under any such  contracts
(subject to such general or specific  instructions as the Trustees may from time
to time adopt) to effect  purchases,  sales,  loans or  exchanges  of  portfolio
securities  and other  investments of the Trust on behalf of the Trustees or may
authorize  any  officer,  employee or Trustee to effect such  purchases,  sales,
loans or exchanges pursuant to recommendations of such Investment  Advisers,  or
any of  them  (and  all  without  further  action  by the  Trustees).  Any  such
purchases, sales, loans and exchanges shall be deemed to have been authorized by
all of the Trustees. The Trustees may, in their sole discretion,  call a meeting
of Shareholders in order to submit to a vote of Shareholders at such meeting the
approval or continuance of any such investment advisory or management  contract.
If the Shareholders of any one or more of the Series of the Trust should fail to
approve any such  investment  advisory or management  contract,  the  Investment
Adviser may nonetheless  serve as Investment  Adviser with respect to any Series
whose Shareholders approve such contract.

         Section  3.3.  Administration  Agreement.  The  Trustees  may in  their
discretion from time to time enter into an  administration  agreement or, if the
Trustees   establish  multiple  Series  or  Classes,   separate   administration
agreements with respect to each Series or Class, whereby the other party to such
agreement  shall  undertake to manage the business  affairs of the Trust or of a
Series or Class  thereof  furnish the Trust or a Series or a Class  thereof with
office  facilities,   and  shall  be  responsible  for  the  ordinary  clerical,
bookkeeping  and  recordkeeping  services at such office  facilities,  and other
facilities  and services,  if any, and all upon such terms and conditions as the
Trustees may in their discretion determine.

         Section 3.4.  Service  Agreement.  The Trustees may in their discretion
from time to time  enter into  Service  Agreements  with  respect to one or more
Series or Classes of Shares whereby the other parties to such Service Agreements
will provide  administration  and/or support services pursuant to Administration
Plans and Service Plans,  and all upon such terms and conditions as the Trustees
in their discretion may determine.

         Section 3.5.  Transfer Agent. The Trustees may in their discretion from
time to time enter  into a transfer  agency  and  shareholder  service  contract
whereby the other party to such  contact  shall  undertake  to furnish  transfer
agency and shareholder  services to the Trust. The contact shall have such terms
<PAGE>

and  conditions as the Trustees may in their  discretion  deem not  inconsistent
with the Declaration. Such services may be provided by one or more Persons.

         Section 3.6.  Custodian.  The Trustees may appoint or otherwise  engage
one or more banks or trust companies,  each having an aggregate capital, surplus
and undivided  profits (as shown in its last  published  report) of at least two
million dollars  ($2,000,000) to serve as Custodian with authority as its agent,
but subject to such restrictions, limitations and other requirements, if any, as
may be  contained in the By-Laws of the Trust.  The Trustees may also  authorize
the  Custodian  to employ one or more sub-  custodians,  including  such foreign
banks  and  securities  depositories  as meet  the  requirements  of  applicable
provisions of the 1940 Act, and upon such terms and  conditions as may be agreed
upon between the Custodian and such sub- custodian, to hold securities and other
assets of the Trust  and to  perform  the acts and  services  of the  Custodian,
subject to applicable provisions of law and resolutions adopted by the Trustees.

         Section 3.7. Affiliations of Trustees or Officers, Etc.  The fact that:

                  (i) any of the Shareholders, Trustees or officers of the Trust
         or any Series thereof is a  shareholder,  director,  officer,  partner,
         trustee,  employee,  manager,  adviser  or  distributor  of or for  any
         partnership,  corporation,  trust, association or other organization or
         of or for any parent or  affiliate  of any  organization,  with which a
         contract of the  character  described in Sections  3.1, 3.2, 3.3 or 3.4
         above or for services as Custodian,  Transfer Agent or disbursing agent
         or for related services may have been or may hereafter be made, or that
         any  such  organization,  or any  parent  or  affiliate  thereof,  is a
         Shareholder of or has an interest in the Trust, or that

                  (ii) any partnership, corporation, trust, association or other
         organization  with  which a  contract  of the  character  described  in
         Sections  3.1,  3.2,  3.3 or 3.4 above or for  services  as  Custodian,
         Transfer  Agent or  disbursing  agent or for related  services may have
         been  or may  hereafter  be  made  also  has  any  one or  more of such
         contracts with one or more other  partnerships,  corporations,  trusts,
         associations  or  other   organizations,   or  has  other  business  or
         interests,  shall not  affect  the  validity  of any such  contract  or
         disqualify any Shareholder, Trustee or officer of the Trust from voting
         upon or executing the same or create any liability or accountability to
         the Trust or its Shareholders.

<PAGE>

         Section  3.8.  Compliance  with 1940 Act.  Any  contract  entered  into
pursuant  to  Sections  3.1 or 3.2 shall be  consistent  with and subject to the
requirements  of Section 15 of the 1940 Act (including any amendment  thereof or
other  applicable  Act  of  Congress  hereafter  enacted),  as  modified  by any
applicable order or orders of the Commission, with respect to its continuance in
effect,  its  termination and the method of  authorization  and approval of such
contract or renewal thereof.


                                   ARTICLE IV

         LIMITATIONS OF LIABILITY OF SHAREHOLDERS, TRUSTEES AND OTHERS

         Section 4.1. No Personal Liability of Shareholders,  Trustees,  Etc. No
Shareholder shall be subject to any personal liability  whatsoever to any Person
in connection  with Trust  Property or the acts,  obligations  or affairs of the
Trust or any Series thereof. No Trustee, officer, employee or agent of the Trust
or any Series thereof shall be subject to any personal  liability  whatsoever to
any Person,  other than to the Trust or its  Shareholders,  in  connection  with
Trust  Property or the affairs of the Trust,  except to the extent  arising from
bad faith,  willful  misfeasance,  gross negligence or reckless disregard of his
duties with  respect to such Person;  and all such Persons  shall look solely to
the Trust  Property,  or to the Property of one or more  specific  Series of the
Trust if the claim arises from the conduct of such Trustee, officer, employee or
agent with respect to only such Series, for satisfaction of claims of any nature
arising  in  connection  with the  affairs  of the  Trust.  If any  Shareholder,
Trustee,  officer,  employee,  or agent,  as such,  of the  Trust or any  Series
thereof, is made a party to any suit or proceeding to enforce any such liability
of the Trust or any Series thereof, he shall not, on account thereof, be held to
any personal  liability.  The Trust shall  indemnify  and hold each  Shareholder
harmless from and against all claims and liabilities,  to which such Shareholder
may become  subject  by reason of his being or having  been a  Shareholder,  and
shall  reimburse such  Shareholder or former  Shareholder  (or his or her heirs,
executors,  administrators  or other legal  representatives  or in the case of a
corporation  or other entity,  its corporate or other general  successor) out of
the Trust Property for all legal and other expenses  reasonably  incurred by him
in  connection  with  any such  claim  or  liability.  The  indemnification  and
reimbursement  required  by the  preceding  sentence  shall be made  only out of
assets of the one or more Series whose Shares were held by said  Shareholder  at
the time the act or event  occurred  which  gave  rise to the claim  against  or
liability of said  Shareholder.  The rights accruing to a Shareholder under this
Section  4.1 shall not impair any other right to which such  Shareholder  may be
<PAGE>

lawfully entitled, nor shall anything herein contained restrict the right of the
Trust or any Series  thereof to  indemnify  or  reimburse a  Shareholder  in any
appropriate situation even though not specifically provided herein.

         Section  4.2.  Non-Liability  of  Trustees,  Etc. No Trustee,  officer,
employee  or agent of the  Trust or any  Series  thereof  shall be liable to the
Trust, its Shareholders,  or to any Shareholder,  Trustee, officer, employee, or
agent thereof for any action or failure to act (including without limitation the
failure to compel in any way any former or acting  Trustee to redress any breach
of trust) except for his own bad faith, willful misfeasance, gross negligence or
reckless disregard of the duties involved in the conduct of his office.

         Section 4.3. Mandatory  Indemnification.  (a) Subject to the exceptions
and limitations contained in paragraph (b) below:

                  (i) every  person  who is, or has been,  a  Trustee,  officer,
         employee or agent of the Trust  (including any individual who serves at
         its  request  as  director,  officer,  partner,  trustee or the like of
         another  organization  in which it has any  interest as a  shareholder,
         creditor or otherwise)  shall be indemnified by the Trust, or by one or
         more Series  thereof if the claim  arises from his or her conduct  with
         respect to only such  Series,  to the fullest  extent  permitted by law
         against all liability and against all expenses  reasonably  incurred or
         paid by him in connection with any claim, action, suit or proceeding in
         which he  becomes  involved  as a party or  otherwise  by virtue of his
         being or having been a Trustee or officer and against  amounts  paid or
         incurred by him in the settlement thereof;

                  (ii) the words  "claim,"  "action,"  "suit,"  or  "proceeding"
         shall  apply  to all  claims,  actions,  suits or  proceedings  (civil,
         criminal, or other, including appeals),  actual or threatened;  and the
         words  "liability" and "expenses"  shall include,  without  limitation,
         attorneys, fees, costs, judgments,  amounts paid in settlement,  fines,
         penalties and other liabilities.

         (b) No  indemnification  shall be  provided  hereunder  to a Trustee or
officer:

                  (i) against any  liability to the Trust,  a Series  thereof or
         the  Shareholders by reason of willful  misfeasance,  bad faith,  gross
         negligence or reckless  disregard of the duties involved in the conduct
         of his office;
<PAGE>

                  (ii) with respect to any matter as to which he shall have been
         finally  adjudicated  not to have acted in good faith in the reasonable
         belief  that his  action  was in the best  interest  of the  Trust or a
         Series thereof;

                  (iii) in the event of a settlement  or other  disposition  not
         involving  a  final  adjudication  as  provided  in  paragraph  (b)(ii)
         resulting in a payment by a Trustee or officer, unless there has been a
         determination  that such  Trustee or officer  did not engage in willful
         misfeasance,  bad faith,  gross negligence or reckless disregard of the
         duties involved in the conduct of his office:

                  (A) by the court or other body  approving  the  settlement  or
         other disposition;

                  (B) based upon a review of readily available facts (as opposed
         to a full  trial-type  inquiry)  by (x) vote of a majority  of the Non-
         interested  Trustees acting on the matter  (provided that a majority of
         the  Non-interested  Trustees  then in office act on the matter) or (y)
         written opinion of independent legal counsel; or

                  (C) by a vote of a  majority  of the  Shares  outstanding  and
         entitled to vote  (excluding  Shares owned of record or beneficially by
         such individual).

         (c) The  rights  of  indemnification  herein  provided  may be  insured
against by  policies  maintained  by the Trust,  shall be  severable,  shall not
affect any other  rights to which any Trustee or officer may now or hereafter be
entitled,  shall  continue  as to a person who has ceased to be such  Trustee or
officer and shall inure to the benefit of the heirs,  executors,  administrators
and assigns of such a person.  Nothing  contained herein shall affect any rights
to  indemnification  to which personnel of the Trust or any Series thereof other
than Trustees and officers may be entitled by contract or otherwise under law.

         (d) Expenses of preparation and presentation of a defense to any claim,
action,  suit or proceeding of the character  described in paragraph (a) of this
Section  4.3 may be  advanced  by the Trust or a Series  thereof  prior to final
disposition  thereof  upon  receipt  of an  undertaking  by or on  behalf of the
recipient  to repay such amount if it is  ultimately  determined  that he is not
entitled to indemnification under this Section 4.3, provided that either:

                  (i) such undertaking is secured by a surety bond or some other
         appropriate security provided by the recipient,  or the Trust or Series
         thereof  shall  be  insured  against  losses  arising  out of any  such
         advances; or g out of

                  (ii) a majority of the  Non-interested  Trustees acting on the
         matter (provided that a majority of the Non-interested  Trustees act on
<PAGE>

         the matter) or an independent  legal counsel in a written opinion shall
         determine,  based upon a review of readily  available facts (as opposed
         to a full trial-type inquiry), that there is reason to believe that the
         recipient ultimately will be found entitled to indemnification.

         As used in this Section 4.3, a "Non-interested  Trustee" is one who (i)
is not an  "Interested  Person"  of the  Trust  (including  anyone  who has been
exempted from being an "Interested  Person" by any rule,  regulation or order of
the  Commission),  and  (ii)  is not  involved  in the  claim,  action,  suit or
proceeding.

         Section  4.4.  No Bond  Required  of  Trustees.  No  Trustee  shall  be
obligated to give any bond or other  security for the  performance of any of his
duties hereunder.

         Section  4.5. No Duty of  Investigation;  Notice in Trust  Instruments,
Etc. No  purchaser,  lender,  transfer  agent or other  Person  dealing with the
Trustees  or any  officer,  employee  or agent of the Trust or a Series  thereof
shall be bound to make any inquiry  concerning  the validity of any  transaction
purporting to be made by the Trustees or by said  officer,  employee or agent or
be liable for the application of money or property paid, loaned, or delivered to
or on the order of the  Trustees or of said  officer,  employee or agent.  Every
obligation,  contract,  instrument,  certificate,  Share,  other security of the
Trust  or a  Series  thereof  or  undertaking,  and  every  other  act or  thing
whatsoever executed in connection with the Trust shall be conclusively  presumed
to have been executed or done by the executors thereof only in their capacity as
Trustees under this  Declaration or in their capacity as officers,  employees or
agents of the Trust or a Series  thereof.  Every written  obligation,  contract,
instrument,  certificate, Share, other security of the Trust or a Series thereof
or  undertaking  made or  issued by the  Trustees  may  recite  that the same is
executed  or  made  by  them  not  individually,   but  as  Trustees  under  the
Declaration, and that the obligations of the Trust or a Series thereof under any
such  instrument  are not  binding  upon  any of the  Trustees  or  Shareholders
individually,  but bind only the Trust  Property  or the Trust  Property  of the
applicable  Series,  and may  contain any  further  recital  which they may deem
appropriate,  but the  omission  of such  recital  shall not operate to bind the
Trustees  individually.  The Trustees shall at all times maintain  insurance for
the  protection of the Trust  Property or the Trust  Property of the  applicable
Series,  its  Shareholders,  Trustees,  officers,  employees  and agents in such
<PAGE>

amount as the Trustees shall deem adequate to cover possible tort liability, and
such  other  insurance  as the  Trustees  in  their  sole  judgment  shall  deem
advisable.

         Section  4.6.  Reliance  on  Experts,  Etc.  Each  Trustee,  officer or
employee  of the Trust or a Series  thereof  shall,  in the  performance  of his
duties,  be fully and completely  justified and protected with regard to any act
or any failure to act  resulting  from  reliance in good faith upon the books of
account or other  records of the Trust or a Series  thereof,  upon an opinion of
counsel,  or upon  reports  made to the Trust or a Series  thereof by any of its
officers or employees  or by the  Investment  Adviser,  the  Administrator,  the
Distributor, Transfer Agent, selected dealers, accountants,  appraisers or other
experts or consultants  selected with reasonable care by the Trustees,  officers
or employees of the Trust, regardless of whether such counsel or expert may also
be a Trustee.


                                   ARTICLE V

                         SHARES OF BENEFICIAL INTEREST

         Section 5.1.  Beneficial  Interest.  The interest of the  beneficiaries
hereunder  shall be divided  into  transferable  Shares of  beneficial  interest
without par value. The number of such Shares of beneficial  interest  authorized
hereunder is unlimited.  The Trustees shall have the exclusive authority without
the  requirement of Shareholder  approval to establish and designate one or more
Series of shares and one or more Classes  thereof as the Trustees deem necessary
or desirable.  Each share of any Series shall  represent an equal  proportionate
Share in the assets of that Series with each other Share in that Series. Subject
to the  provisions of Section 5.11 hereof,  the Trustees may also  authorize the
creation of  additional  Series of Shares (the proceeds of which may be invested
in separate,  independently managed portfolios) and additional Classes of Shares
within any Series. All Shares issued hereunder  including,  without  limitation,
Shares  issued in  connection  with a  dividend  in Shares or a split in Shares,
shall be fully paid and nonassessable by the Trust.

         Section  5.2.  Rights  of  Shareholders.  The  ownership  of the  Trust
Property of every description and the right to conduct any business hereinbefore
described are vested  exclusively in the Trustees,  and the  Shareholders  shall
have no interest therein other than the beneficial  interest  conferred by their
Shares,  and they shall have no right to call for any  partition  or division of
any property,  profits,  rights or interests of the Trust nor can they be called
upon to share or assume any losses of the Trust or suffer an  assessment  of any
<PAGE>

kind by virtue of their  ownership  of  Shares.  The  Shares  shall be  personal
property giving only the rights specifically set forth in this Declaration.  The
Shares  shall not  entitle  the  holder to  preference,  preemptive,  appraisal,
conversion or exchange rights, except as the Trustees may determine with respect
to any Series or Class of Shares.

         Section 5.3.  Trust Only. It is the intention of the Trustees to create
only the  relationship of Trustee and beneficiary  between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a  general   partnership,   limited   partnership,   joint  stock   association,
corporation,  bailment  or any form of legal  relationship  other  than a trust.
Nothing  in  this   Declaration   of  Trust  shall  be  construed  to  make  the
Shareholders,  either by themselves or with the Trustees, partners or members of
a joint stock association.

         Section 5.4. Issuance of Shares.  The Trustees in their discretion may,
from time to time without vote of the Shareholders, issue Shares, in addition to
the then issued and outstanding Shares and Shares held in the treasury,  to such
party or parties and for such amount and type of  consideration,  including cash
or  property,  at such time or times and on such terms as the  Trustees may deem
best,  except that only Shares  previously  contracted  to be sold may be issued
during any period when the right of redemption is suspended  pursuant to Section
6.9  hereof,  and  may in  such  manner  acquire  other  assets  (including  the
acquisition  of assets  subject to, and in connection  with the  assumption  of,
liabilities)  and  businesses.  In connection  with any issuance of Shares,  the
Trustees  may issue  fractional  Shares and  Shares  held in the  treasury.  The
Trustees  may from time to time divide or combine the Shares of the Trust or, if
the Shares be divided into Series or Classes, of any Series or any Class thereof
of the Trust,  into a greater or lesser  number  without  thereby  changing  the
proportionate  beneficial  interests  in  the  Trust  or in the  Trust  Property
allocated or belonging  to such Series or Class.  Contributions  to the Trust or
Series  thereof may be accepted  for,  and Shares  shall be redeemed  as,  whole
Shares and/or 1/1,000ths of a Share or integral multiples thereof.

         Section  5.5.  Register  of  Shares.  A  register  shall be kept at the
principal  office of the Trust or an office of the  Transfer  Agent  which shall
contain the names and  addresses  of the  Shareholders  and the number of Shares
held by them respectively and a record of all transfers  thereof.  Such register
shall be  conclusive  as to who are the  holders  of the Shares and who shall be
entitled to receive dividends or distributions or otherwise to exercise or enjoy
the rights of Shareholders.  No Shareholder shall be entitled to receive payment
of any  dividend or  distribution,  nor to have notice  given to him as provided
herein or in the By-laws,  until he has given his address to the Transfer  Agent
<PAGE>

or such other  officer or agent of the Trustees as shall keep the said  register
for entry thereon.  It is not contemplated  that certificates will be issued for
the Shares;  however,  the  Trustees,  in their  discretion,  may  authorize the
issuance of share certificates and promulgate  appropriate rules and regulations
as to their use.

         Section 5.6.  Transfer of Shares.  Shares shall be  transferable on the
records of the Trust only by the record holder thereof or by his agent thereunto
duly authorized in writing,  upon delivery to the Trustees or the Transfer Agent
of a duly executed  instrument  of transfer,  together with such evidence of the
genuineness of each such execution and authorization and of other matters as may
reasonably be required. Upon such delivery the transfer shall be recorded on the
register of the Trust.  Until such  record is made,  the  Shareholder  of record
shall be deemed to be the holder of such Shares for all purposes  hereunder  and
neither the  Trustees  nor any  transfer  agent or  registrar  nor any  officer,
employee or agent of the Trust  shall be affected by any notice of the  proposed
transfer.

         Any person becoming entitled to any Shares in consequence of the death,
bankruptcy or incompetence of any Shareholder, or otherwise by operation of law,
shall be  recorded  on the  register of Shares as the holder of such Shares upon
production of the proper evidence thereof to the Trustees or the Transfer Agent,
but until such record is made,  the  Shareholder of record shall be deemed to be
the holder of such Shares for all  purposes  hereunder  and neither the Trustees
nor any Transfer  Agent or registrar nor any officer or agent of the Trust shall
be affected by any notice of such death,  bankruptcy or  incompetence,  or other
operation of law.

         Section 5.7. Notices.  Any and all notices to which any Shareholder may
be entitled and any and all communications  shall be deemed duly served or given
if mailed,  postage prepaid,  addressed to any Shareholder of record at his last
known address as recorded on the register of the Trust.

         Section 5.8. Treasury Shares.  Shares held in the treasury shall, until
resold  pursuant to Section 5.4, not confer any voting  rights on the  Trustees,
nor shall  such  Shares be  entitled  to any  dividends  or other  distributions
declared with respect to the Shares.

         Section 5.9. Voting Powers.  The Shareholders  shall have power to vote
only (i) for the  election of Trustees  as provided in Section  2.13;  (ii) with
respect to any  investment  advisory  contract  entered into pursuant to Section
3.2; (iii) with respect to termination of the Trust or a Series or Class thereof
<PAGE>

as  provided  in  Section  8.2;  (iv)  with  respect  to any  amendment  of this
Declaration  to the extent and as provided in Section  8.3;  (v) with respect to
any merger,  consolidation  or sale of assets as provided in Section  8.4;  (vi)
with  respect to  incorporation  of the Trust to the extent and as  provided  in
Section 8.5;  (vii) to the same extent as the  stockholders  of a  Massachusetts
business  corporation  as to whether or not a court action,  proceeding or claim
should or should not be brought or maintained  derivatively or as a class action
on behalf of the Trust or a Series thereof or the Shareholders of either; (viii)
with respect to any plan adopted pursuant to Rule 1 2b-1 (or any successor rule)
under the 1940 Act, and related  matters,  to the extent required under the 1940
Act; and (ix) with respect to such additional  matters  relating to the Trust as
may be required by this Declaration, the Bylaws or any registration of the Trust
as an  investment  company  under  the  1940 Act  with  the  Commission  (or any
successor agency) or as the Trustees may consider  necessary or desirable.  Each
whole  Share  shall  be  entitled  to one vote as to any  matter  on which it is
entitled to vote and each fractional  Share shall be entitled to a proportionate
fractional vote. On any matter  submitted to a vote of Shareholders,  all Shares
shall be voted by individual  Series except (1) when  permitted by the 1940 Act,
Shares shall be voted in the  aggregate and not by  individual  Series;  and (2)
when the Trustees have  determined that the matter affects only the interests of
one or more Series or Class thereof,  then only the  Shareholders of such Series
or Class  thereof  shall be  entitled  to vote  thereon.  The  Trustees  may, in
conjunction  with the  establishment  of any  further  Series or any  Classes of
Shares, establish conditions under which the several Series or Classes of Shares
shall  have  separate  voting  rights or no  voting  rights.  There  shall be no
cumulative  voting in the  election of Trustees.  Until  Shares are issued,  the
Trustees  may  exercise  all  rights  of  Shareholders  and may take any  action
required by law, this  Declaration  or the By-laws to be taken by  Shareholders.
The Bylaws may include further  provisions for Shareholders,  votes and meetings
and related matters.

         Section 5.10.  Meetings of Shareholders.  No annual or regular meetings
of Shareholders are required.  Special meetings of the  Shareholders,  including
meetings  involving  only the holders of Shares of one or more but less than all
Series or  Classes  thereof,  may be called at any time by the  Chairman  of the
Board, President, or any Vice President of the Trust, and shall be called by the
President or the  Secretary at the request,  in writing or by  resolution,  of a
majority of the Trustees,  or at the written request of the holder or holders of
ten  percent  (10%) or more of the  total  number  of  Shares  then  issued  and
outstanding  of the Trust  entitled  to vote at such  meeting.  Meetings  of the
Shareholders  of any Series of the Trust shall be called by the President or the
<PAGE>

Secretary at the written  request of the holder or holders of ten percent  (10%)
or more of the total number of Shares then issued and outstanding of such Series
of the Trust entitled to vote at such meeting.  Any such request shall state the
purpose of the proposed meeting.

         Section 5.11.  Series or Class  Designation.  (a) Without  limiting the
authority of the Trustees  set forth in Section 5.1 to establish  and  designate
any  further  Series,  it is hereby  confirmed  that the Trust  consists  of the
presently  Outstanding  Shares of one Series:  Pioneer Bond Fund (the  "Existing
Series").

         (b) Without limiting the authority of the Trustees set forth in Section
5.1 to establish and designate any further Classes,  it is hereby confirmed that
each Series of the Trust's Shares consists of a single Class.

         (c) The Shares of the  Existing  Series and each Class  thereof  herein
established and designated and any Shares of any further Series and Classes that
may from time to time be  established  and  designated by the Trustees  shall be
established  and  designated,  and the  variations  in the  relative  rights and
preferences as between the different  Series shall be fixed and  determined,  by
the Trustees  (unless the Trustees  otherwise  determine with respect to further
Series  or  Classes  at the time of  establishing  and  designating  the  same);
provided, that all Shares shall be identical except that there may be variations
so fixed and  determined  between  different  Series or  Classes  thereof  as to
investment  objective,  policies  and  restrictions,   purchase  price,  payment
obligations,  distribution expenses,  right of redemption,  special and relative
rights as to dividends and on liquidation,  conversion rights,  exchange rights,
and conditions under which the several Series shall have separate voting rights,
all of which are subject to the limitations  set forth below.  All references to
Shares in this Declaration  shall be deemed to be Shares of any or all Series or
Classes as the context may require.

         (d) As to any existing  Series and Classes,  both heretofore and herein
established and designated, and any further division of Shares of the Trust into
additional Series or Classes, the following provisions shall be applicable:

                  (i) The number of  authorized  Shares and the number of Shares
         of each Series or Class  thereof that may be issued shall be unlimited.
         The  Trustees  may classify or  reclassify  any unissued  Shares or any
         Shares previously issued and reacquired of any Series or Class into one
         or more  Series  or one or more  Classes  that may be  established  and
         designated  from time to time. The Trustees may hold as treasury shares
         (of the  same  or  some  other  Series  or  Class),  reissue  for  such
<PAGE>

         consideration  and on such terms as they may  determine,  or cancel any
         Shares  of any  Series  or  Class  reacquired  by the  Trust  at  their
         discretion from time to time.

                  (ii) All consideration  received by the Trust for the issue or
         sale of Shares of a  particular  Series  or  Class,  together  with all
         assets in which such  consideration  is  invested  or  reinvested,  all
         income, earnings,  profits and proceeds thereof, including any proceeds
         derived from the sale,  exchange or liquidation of such assets, and any
         funds or payments  derived from any  reinvestment  of such  proceeds in
         whatever form the same may be, shall irrevocably  belong to that Series
         for all  purposes,  subject  only to the  rights of  creditors  of such
         Series and except as may otherwise be required by applicable  tax laws,
         and shall be so recorded upon the books of account of the Trust. In the
         event that there are any assets, income, earnings, profits and proceeds
         thereof,  funds or  payments  which  are not  readily  identifiable  as
         belonging to any  particular  Series,  the Trustees shall allocate them
         among any one or more of the Series  established  and  designated  from
         time to time in such  manner and on such  basis as they,  in their sole
         discretion,  deem  fair and  equitable.  Each  such  allocation  by the
         Trustees shall be conclusive and binding upon the  Shareholders  of all
         Series for all  purposes.  No holder of Shares of any Series shall have
         any claim on or right to any assets allocated or belonging to any other
         Series.

                  (iii) The assets belonging to each particular  Series shall be
         charged with the  liabilities of the Trust in respect of that Series or
         the  appropriate  Class or Classes  thereof  and all  expenses,  costs,
         charges and  reserves  attributable  to that Series or Class or Classes
         thereof,  and any  general  liabilities,  expenses,  costs,  charges or
         reserves of the Trust which are not readily  identifiable  as belonging
         to any particular Series shall be allocated and charged by the Trustees
         to and among any one or more of the Series  established  and designated
         from time to time in such  manner and on such basis as the  Trustees in
         their sole  discretion  deem fair and  equitable.  Each  allocation  of
         liabilities,  expenses,  costs,  charges and  reserves by the  Trustees
         shall be conclusive and binding upon the Shareholders of all Series and
         Classes for all purposes.  The Trustees shall have full discretion,  to
         the extent not inconsistent with the 1940 Act, to determine which items
         are  capital;  and each  such  determination  and  allocation  shall be
         conclusive  and  binding  upon  the  Shareholders.   The  assets  of  a
         particular  Series  of the  Trust  shall,  under no  circumstances,  be
         charged  with  liabilities  attributable  to any other  Series or Class
         thereof of the Trust.  All persons  extending credit to, or contracting
<PAGE>

         with or having any claim  against a  particular  Series or Class of the
         Trust  shall  look only to the  assets of that  particular  Series  for
         payment of such credit, contract or claim.

                  (iv)  The  power of the  Trustees  to pay  dividends  and make
         distributions shall be governed by Section 7.2 of this Declaration with
         respect to any Series or Classes  which  represent the interests in the
         assets of the Trust  immediately  prior to the  establishment of two or
         more  Series or  Classes.  With  respect to any other  Series or Class,
         dividends and  distributions on Shares of a particular  Series or Class
         may be paid with such  frequency as the Trustees may  determine,  which
         may be  daily  or  otherwise,  pursuant  to a  standing  resolution  or
         resolutions  adopted  only once or with such  frequency as the Trustees
         may determine,  to the holders of Shares of that Series or Class,  from
         such of the income and capital  gains,  accrued or  realized,  from the
         assets belonging to that Series,  as the Trustees may determine,  after
         providing for actual and accrued  liabilities  belonging to that Series
         or Class.  All  dividends and  distributions  on Shares of a particular
         Series or Class shall be distributed  pro rata to the  Shareholders  of
         that  Series  or Class in  proportion  to the  number of Shares of that
         Series  or  Class  held  by such  Shareholders  at the  time of  record
         established for the payment of such dividends or distribution.

                  (v) Each  Share of a Series of the  Trust  shall  represent  a
         beneficial  interest in the net assets of such  Series.  Each holder of
         Shares of a Series or Class  thereof  shall be  entitled to receive his
         pro rata share of  distributions  of income and capital gains made with
         respect to such Series or Class net of expenses. Upon redemption of his
         Shares or  indemnification  for  liabilities  incurred by reason of his
         being  or  having  been  a  Shareholder  of a  Series  or  Class,  such
         Shareholder  shall be paid solely out of the funds and property of such
         Series of the Trust.  Upon  liquidation  or  termination of a Series or
         Class  thereof  of the  Trust,  Shareholders  of such  Series  or Class
         thereof shall be entitled to receive a pro rata share of the net assets
         of such Series. A Shareholder of a particular Series of the Trust shall
         not be entitled  to  participate  in a  derivative  or class  action on
         behalf of any other Series or the  Shareholders  of any other Series of
         the Trust.

                  (vi) On each matter submitted to a vote of  Shareholders,  all
         Shares  of all  Series  and  Classes  shall  vote  as a  single  class;
         provided,  however,  that (1) as to any matter with  respect to which a
         separate  vote of any Series or Class is required by the 1940 Act or is
<PAGE>

         required by attributes applicable to any Series or Class or is required
         by any Rule 12b-1 plan, such requirements as to a separate vote by that
         Series or Class shall apply;  (2) to the extent that a matter  referred
         to in clause  (1) above  affects  more than one Class or Series and the
         interests  of each such Class or Series in the  matter  are  identical,
         then,  subject  to clause (3)  below,  the Shares of all such  affected
         Classes or Series  shall vote as a single  Class;  (3) as to any matter
         which does not affect the  interests of a  particular  Series or Class,
         only the  holders  of  Shares  of the one or more  affected  Series  or
         Classes  shall be  entitled  to  vote;  and (4) the  provisions  of the
         following  sentence  shall  apply.  On any matter that  pertains to any
         particular  Class of a particular  Series or to any Class expenses with
         respect  to any  Series  which  matter  may be  submitted  to a vote of
         Shareholders,  only Shares of the affected Class or that Series, as the
         case may be, shall be entitled to vote except  that:  (x) to the extent
         said  matter  affects  Shares of another  Class or  Series,  such other
         Shares shall also be entitled to vote,  and in such cases Shares of the
         affected  Class,  as the case may be, of such Series  shall be voted in
         the aggregate  together  with such other Shares;  and (y) to the extent
         that said matter does not affect  Shares of a particular  Class of such
         Series,  said  Shares  shall  not be  entitled  to vote  (except  where
         otherwise  required by law or permitted by the Trustees acting in their
         sole  discretion)  even though the matter is submitted to a vote of the
         Shareholders of any other Class or Series.

                  (vii)  Except as  otherwise  provided  in this  Article V, the
         Trustees   shall  have  the  power  to  determine   the   designations,
         preferences,  privileges, payment obligations,  limitations and rights,
         including  voting  and  dividend  rights,  of each  Class and Series of
         Shares.  Subject to compliance  with the  requirements of the 1940 Act,
         the  Trustees  shall have the  authority to provide that the holders of
         Shares  of any  Series or Class  shall  have the  right to  convert  or
         exchange  said  Shares  into Shares of one or more Series or Classes of
         Shares in accordance with such requirements,  conditions and procedures
         as may be established by the Trustees.

                  (viii)  The  establishment  and  designation  of any Series or
         Classes of Shares shall be effective  upon the  execution by a majority
         of the then Trustees of an instrument  setting forth such establishment
         and  designation and the relative rights and preferences of such Series
         or Classes,  or as otherwise  provided in such instrument.  At any time
         that there are no Shares  outstanding of any particular Series or Class
         previously   established  and  designated,   the  Trustees  may  by  an
         instrument  executed by a majority of their number  abolish that Series
<PAGE>

         or Class and the establishment and designation thereof. Each instrument
         referred to in this  section  shall have the status of an  amendment to
         this Declaration.

         Section 5.12.  Assent to Declaration of Trust.  Every  Shareholder,  by
virtue of having become a Shareholder,  shall be held to have expressly assented
and agreed to the terms hereof and to have become a party hereto.


                                   ARTICLE VI

                      REDEMPTION AND REPURCHASE OF SHARES

         Section 6.1. Redemption of Shares. (a) All Shares of the Trust shall be
redeemable,  at the  redemption  price  determined in the manner set out in this
Declaration.  Redeemed  or  repurchased  Shares may be resold by the Trust.  The
Trust may  require  any  Shareholder  to pay a sales  charge to the  Trust,  the
underwriter,  or any other person  designated by the Trustees upon redemption or
repurchase  of  Shares  in such  amount  and upon  such  conditions  as shall be
determined from time to time by the Trustees.

         (b) The Trust  shall  redeem  the  Shares of the Trust or any Series or
Class  thereof  at the price  determined  as  hereinafter  set  forth,  upon the
appropriately verified written application of the record holder thereof (or upon
such other form of request as the  Trustees  may  determine)  at such  office or
agency as may be designated  from time to time for that purpose by the Trustees.
The  Trustees  may  from  time  to  time  specify  additional  conditions,   not
inconsistent  with the 1940  Act,  regarding  the  redemption  of  Shares in the
Trust's then effective Prospectus.

         Section 6.2. Price.  Shares shall be redeemed at a price based on their
net asset value determined as set forth in Section 7.1 hereof as of such time as
the Trustees shall have theretofore prescribed by resolution.  In the absence of
such resolution,  the redemption price of Shares deposited shall be based on the
net asset  value of such  Shares  next  determined  as set forth in Section  7.1
hereof after receipt of such application.  The amount of any contingent deferred
sales charge or redemption fee payable upon redemption of Shares may be deducted
from the proceeds of such redemption.

         Section 6.3. Payment.  Payment of the redemption price of Shares of the
Trust or any Series or Class thereof shall be made in cash or in property to the
Shareholder at such time and in the manner,  not inconsistent  with the 1940 Act
or other  applicable  laws, as may be specified from time to time in the Trust's
<PAGE>

then  effective  Prospectus,  subject to the  provisions  of Section 6.4 hereof.
Notwithstanding  the foregoing,  the Trustees may withhold from such  redemption
proceeds any amount arising (i) from a liability of the redeeming Shareholder to
the  Trust or (ii) in  connection  with any  Federal  or state  tax  withholding
requirements.

         Section 6.4. Effect of Suspension of  Determination of Net Asset Value.
If,  pursuant to Section 6.9 hereof,  the Trustees shall declare a suspension of
the  determination  of net asset value with respect to Shares of the Trust or of
any Series or Class thereof,  the rights of  Shareholders  (including  those who
shall have applied for  redemption  pursuant to Section 6.1 hereof but who shall
not yet have received payment) to have Shares redeemed and paid for by the Trust
or a Series or Class thereof shall be suspended  until the  termination  of such
suspension is declared. Any record holder who shall have his redemption right so
suspended may,  during the period of such  suspension,  by  appropriate  written
notice of revocation at the office or agency where  application was made, revoke
any application  for redemption not honored and withdraw any Share  certificates
on deposit.  The redemption  price of Shares for which  redemption  applications
have not been revoked  shall be based on the net asset value of such Shares next
determined as set forth in Section 7.1 after the termination of such suspension,
and payment  shall be made  within  seven (7) days after the date upon which the
application  was made plus the period  after such  application  during which the
determination of net asset value was suspended.

         Section 6.5.  Repurchase by Agreement.  The Trust may repurchase Shares
directly,  or through  the  Distributor  or  another  agent  designated  for the
purpose,  by agreement  with the owner  thereof at a price not exceeding the net
asset value per share determined as of the time when the purchase or contract of
purchase  is made or the net  asset  value  as of any  time  which  may be later
determined pursuant to Section 7.1 hereof,  provided payment is not made for the
Shares prior to the time as of which such net asset value is determined.

         Section 6.6.  Redemption of Shareholder's  Interest.  The Trustees,  in
their sole discretion, may cause the Trust to redeem all of the Shares of one or
more Series or Class thereof held by any Shareholder if the value of such Shares
held by such  Shareholder is less than the minimum amount  established from time
to time by the Trustees.

         Section  6.7.  Redemption  of Shares in Order to Qualify  as  Regulated
Investment  Company;  Disclosure of Holding.  (a) If the Trustees  shall, at any
time and in good faith,  be of the opinion that direct or indirect  ownership of
Shares or other  securities of the Trust has or may become  concentrated  in any
<PAGE>

Person to an extent which would  disqualify the Trust or any Series of the Trust
as a regulated  investment company under the Internal Revenue Code of 1986, then
the Trustees shall have the power by lot or other means deemed equitable by them
(i) to call for redemption by any such Person a number,  or principal amount, of
Shares or other securities of the Trust or any Series of the Trust sufficient to
maintain or bring the direct or indirect ownership of Shares or other securities
of the Trust or any Series of the Trust into  conformity  with the  requirements
for such  qualification  and (ii) to refuse to transfer or issue Shares or other
securities  of the  Trust  or  any  Series  of the  Trust  to any  Person  whose
acquisition of the Shares or other  securities of the Trust or any Series of the
Trust in question would result in such disqualification. The redemption shall be
effected at the redemption price and in the manner provided in Section 6.1.

         (b) The  holders  of  Shares  or other  securities  of the Trust or any
Series of the Trust shall upon demand  disclose to the  Trustees in writing such
information  with  respect to direct and  indirect  ownership of Shares or other
securities  of the  Trust  or any  Series  of the  Trust  as the  Trustees  deem
necessary to comply with the provisions of the Internal Revenue Code of 1986, as
amended, or to comply with the requirements of any other taxing authority.

         Section 6.8. Reductions in Number of Outstanding Shares Pursuant to Net
Asset Value Formula.  The Trust may also reduce the number of outstanding Shares
of the Trust or any Series of the Trust  pursuant to the  provisions  of Section
7.3.

         Section 6.9. Suspension of Right of Redemption. The Trust may declare a
suspension  of the  right of  redemption  or  postpone  the date of  payment  or
redemption for the whole or any part of any period (i) during which the New York
Stock Exchange is closed other than customary weekend and holiday closings, (ii)
during which trading on the New York Stock Exchange is restricted,  (iii) during
which an emergency exists as a result of which disposal by the Trust or a Series
thereof of securities  owned by it is not  reasonably  practicable  or it is not
reasonably practicable for the Trust or a Series thereof fairly to determine the
value of its net assets, or (iv) during any other period when the Commission may
for the protection of  Shareholders  of the Trust by order permit  suspension of
the right of redemption or  postponement  of the date of payment or  redemption;
provided that applicable rules and regulations of the Commission shall govern as
to whether the conditions prescribed in clauses (ii), (iii), or (iv) exist. Such
suspension  shall take  effect at such time as the Trust  shall  specify but not
later  than the  close of  business  on the  business  day  next  following  the
declaration of suspension,  and thereafter there shall be no right of redemption
or payment on redemption until the Trust shall declare the suspension at an end,
<PAGE>

except  that the  suspension  shall  terminate  in any event on the first day on
which said stock exchange shall have reopened or the period specified in (ii) or
(iii) shall have  expired  (as to which in the absence of an official  ruling by
the Commission, the determination of the Trust shall be conclusive). In the case
of a suspension of the right of redemption,  a Shareholder  may either  withdraw
his  request for  redemption,  or receive  payment  based on the net asset value
existing after the termination of the suspension.


                                  ARTICLE VII

                       DETERMINATION OF NET ASSET VALUE,
                          NET INCOME AND DISTRIBUTIONS

         Section 7.1. Net Asset Value.  The net asset value of each  outstanding
Share of the Trust or of each Series or Class  thereof  shall be  determined  on
such days and at such time or times as the Trustees may determine.  The value of
the assets of the Trust or any Series thereof may be determined (i) by a pricing
service  which  utilizes   electronic   pricing   techniques  based  on  general
institutional trading, (ii) by appraisal of the securities owned by the Trust or
any Series of the Trust,  (iii) in certain cases,  at amortized cost, or (iv) by
such  other  method  as shall be  deemed  to  reflect  the fair  value  thereof,
determined  in good faith by or under the  direction of the  Trustees.  From the
total value of said assets, there shall be deducted all indebtedness,  interest,
taxes, payable or accrued, including estimated taxes on unrealized book profits,
expenses  and  management  charges  accrued to the  appraisal  date,  net income
determined and declared as a  distribution  and all other items in the nature of
liabilities  which shall be deemed  appropriate,  as incurred by or allocated to
the Trust or any Series or Class of the Trust.  The resulting amount which shall
represent  the total net assets of the Trust or Series or Class thereof shall be
divided  by the  number  of  Shares  of the  Trust or  Series  or Class  thereof
outstanding  at the time and the quotient so obtained  shall be deemed to be the
net asset value of the Shares of the Trust or Series or Class  thereof.  The net
asset value of the Shares  shall be  determined  at least once on each  business
day, as of the close of regular  trading on the New York Stock Exchange or as of
such other time or times as the Trustees shall determine.  The power and duty to
make the daily  calculations  may be delegated by the Trustees to the Investment
Adviser,  the  Administrator,  the  Custodian,  the Transfer Agent or such other
Person as the Trustees by resolution may determine. The Trustees may suspend the
dally  determination of net asset value to the extent permitted by the 1940 Act.
It shall not be a violation  of any  provision of this  Declaration  of Trust if
<PAGE>

Shares are sold,  redeemed or repurchased by the Trust at a price other than one
based on net  asset  value if the net  asset  value is  affected  by one or more
errors  inadvertently made in the pricing of portfolio securities or in accruing
income, expenses or liabilities.

         Section 7.2. Distributions to Shareholders. (a) The Trustees shall from
time to time  distribute  ratably  among the  Shareholders  of the Trust or of a
Series or Class thereof such proportion of the net profits,  surplus  (including
paid-in  surplus),  capital,  or assets of the Trust or such  Series held by the
Trustees  as they may deem  proper.  Such  distributions  may be made in cash or
property  (including  without limitation any type of obligations of the Trust or
Series or Class or any assets thereof),  and the Trustees may distribute ratably
among the Shareholders of the Trust or Series or Class thereof additional Shares
of the Trust or Series or Class thereof  issuable  hereunder in such manner,  at
such  times,  and  on  such  terms  as  the  Trustees  may  deem  proper.   Such
distributions  may be among  the  Shareholders  of the  Trust or Series or Class
thereof at the time of declaring a distribution or among the Shareholders of the
Trust or Series or Class thereof at such other date or time or dates or times as
the Trustees shall  determine.  The Trustees may in their  discretion  determine
that, solely for the purposes of such  distributions,  Outstanding  Shares shall
exclude Shares for which orders have been placed  subsequent to a specified time
on the date the  distribution  is declared or on the next  preceding  day if the
distribution  is  declared  as of a day on which  Boston  banks are not open for
business,  all as described in the then effective  Prospectus.  The Trustees may
always retain from the net profits such amount as they may deem necessary to pay
the  debts or  expenses  of the Trust or a Series  or Class  thereof  or to meet
obligations  of the  Trust or a Series  or  Class  thereof,  or as they may deem
desirable  to  use  in the  conduct  of its  affairs  or to  retain  for  future
requirements or extensions of the business.  The Trustees may adopt and offer to
Shareholders  such dividend  reinvestment  plans,  cash dividend payout plans or
related plans as the Trustees shall deem appropriate.  The Trustees may in their
discretion determine that an account  administration fee or other similar charge
may be deducted directly from the income and other  distributions paid on Shares
to a Shareholder's account in each Series or Class of the Trust.

         (b)  Inasmuch  as the  computation  of net income and gains for Federal
income tax  purposes  may vary from the  computation  thereof on the books,  the
above  provisions  shall be  interpreted to give the Trustees the power in their
discretion  to  distribute  for any fiscal  year as  ordinary  dividends  and as
capital gains  distributions,  respectively,  additional  amounts  sufficient to
enable the Trust or a Series or Class  thereof to avoid or reduce  liability for
taxes.
<PAGE>

         Section 7.3.  Determination  of Net Income;  Reduction  of  Outstanding
Shares. Subject to Section 5.11 hereof, the net income of the Series and Classes
thereof of the Trust shall be  determined  in such manner as the Trustees  shall
provide by  resolution.  Expenses of the Trust or of a Series or Class  thereof,
including the advisory or management  fee, shall be accrued each day. Each Class
shall bear only expenses relating to its Shares and an allocable share of Series
expenses in accordance  with such policies as may be established by the Trustees
from  time to time  and as are not  inconsistent  with  the  provisions  of this
Declaration of Trust or of any  applicable  document filed by the Trust with the
Commission or of the Internal Revenue Code of 1986, as amended.  Such net income
may be  determined  by or under the direction of the Trustees as of the close of
trading on the New York Stock  Exchange on each day on which such market is open
or as of such other time or times as the Trustees shall  determine,  and, except
as provided  herein,  all the net income of any Series or Class of the Trust, as
so determined,  may be declared as a dividend on the Outstanding  Shares of such
Series or Class.  The Trustees  shall have the authority at any time and for any
reason to reduce  the number of Shares of any  Series or Class by  reducing  the
number of Shares of such  Series  or Class by  reducing  the  number of full and
fractional shares outstanding in any such Series or Class.  Without limiting the
generality of the foregoing, if, for any reason, the net income of any Series or
Class of the Trust  determined at any time is a negative amount or for any other
reason,  the Trustees  shall have the power with respect to such Series or Class
(i) to offset each Shareholder's pro rata share of such negative amount from the
accrued  dividend account of such  Shareholder,  or (ii) to reduce the number of
"Outstanding  Shares of such Series or Class by reducing the number of Shares in
the account of such  Shareholder  by that number of full and  fractional  Shares
which  represents  the amount of such excess  negative  net income,  or (iii) to
cause to be recorded on the books of the Trust an asset account in the amount of
such negative net income, which account may be reduced by such amount; provided,
that the same shall  thereupon  become the property of the Trust with respect to
such  Series or Class and shall not be paid to any  Shareholder,  and  provided,
further,  that dividends  shall not be declared upon the  Outstanding  Shares of
such  Series  or  Class  on or  after  the  day  such  negative  net  income  is
experienced,  until such asset  account is reduced to zero.  The Trustees  shall
have full discretion to determine whether any cash or property received shall be
treated as income or as  principal  and  whether  any item of  expense  shall be
charged to the income or the principal account,  and their determination made in
good  faith  shall be  conclusive  upon the  Shareholders.  In the case of stock
dividends received, the Trustees shall have full discretion to determine, in the
light of the  particular  circumstances,  how much if any of the  value  thereof
shall be treated as income, the balance, if any, to be treated as principal.
<PAGE>

         Section 7.4. Power to Modify Foregoing Procedures.  Notwithstanding any
of the  foregoing  provisions  of this  Article VII, but subject to Section 5.11
hereof,  the Trustees may prescribe,  in their absolute  discretion,  such other
bases and times for  determining  the per Share net asset value of the Shares of
the Trust or a Series or Class thereof or net income of the Trust or a Series or
Class thereof,  or the declaration and payment of dividends and distributions as
they may deem  necessary or desirable.  Without  limiting the  generality of the
foregoing,  the Trustees may  establish  several  Series or Classes of Shares in
accordance with Section 5.11, and declare  dividends  thereon in accordance with
Section 5.11(d)(iv).


                                  ARTICLE VIII

              DURATION; TERMINATION OF TRUST OR A SERIES OR CLASS;
                            AMENDMENT; MERGERS, ETC.

         Section 8.1.  Duration.  The Trust shall continue without limitation of
time but subject to the provisions of this Article VIII.

         Section 8.2. Termination of the Trust or a Series or a Class. The Trust
or any Series or Class thereof may be terminated by (i) the affirmative  vote of
the holders of not less than  two-thirds of the Shares  outstanding and entitled
to vote at any meeting of Shareholders of the Trust or the appropriate Series or
Class  thereof,  (ii) by an  instrument  or  instruments  in  writing  without a
meeting, consented to by the holders of two-thirds of the Shares of the Trust or
the  appropriate  Series  or  Class  thereof;  provided,  however,  that if such
termination is recommended by the Trustees,  the vote or written  consent of the
holders of a majority  of the Shares of the Trust or the  appropriate  Series or
Class thereof outstanding and entitled to vote shall be sufficient authorization
for such termination,  or (iii) notice to Shareholders by means of an instrument
in writing signed by a majority of the Trustees,  stating that a majority of the
Trustees has determined that the  continuation of the Trust or a Series or Class
thereof is not in the best interest of such Series or Class,  the Trust or their
respective shareholders as a result of factors or events adversely affecting the
ability  of such  Series or a Class or the Trust to  conduct  its  business  and
operations in an economically viable manner. Such factors and events may include
(but are not  limited  to) the  inability  of a Series  or Class or the Trust to
<PAGE>

maintain  its assets at an  appropriate  size,  changes  in laws or  regulations
governing  the Series or Class or the Trust or  affecting  assets of the type in
which such  Series or Class or the Trust  invests or  economic  developments  or
trends having a significant adverse impact on the business or operations of such
Series or Class or the Trust. Upon the termination of the Trust or the Series or
Class:

                  (i) The  Trust,  Series or Class  shall  carry on no  business
         except for the purpose of winding up its affairs;

                  (ii) The Trustees  shall proceed to wind up the affairs of the
         Trust, Series or Class and all of the powers of the Trustees under this
         Declaration  shall continue  until the affairs of the Trust,  Series or
         Class  shall  have been  wound up,  including  the power to  fulfill or
         discharge  the  contracts  of the Trust,  Series or Class,  collect its
         assets, sell, convey, assign,  exchange,  transfer or otherwise dispose
         of all or any part of the remaining  Trust  Property or Trust  Property
         allocated  or  belonging to such Series or Class to one or more persons
         at public or private sale for consideration  which may consist in whole
         or in part of cash, securities or other property of any kind, discharge
         or pay its liabilities,  and do all other acts appropriate to liquidate
         its business; provided that any sale, conveyance, assignment, exchange,
         transfer or other  disposition  of all or  substantially  all the Trust
         Property or Trust  Property  allocated  or  belonging to such Series or
         Class that requires Shareholder approval in accordance with Section 8.4
         hereof shall receive the approval so required; and

                  (iii) After paying or adequately  providing for the payment of
         all  liabilities,  and upon receipt of such releases,  indemnities  and
         refunding  agreements as they deem necessary for their protection,  the
         Trustees may distribute  the remaining  Trust Property or the remaining
         property  of the  terminated  Series  or  Class,  in cash or in kind or
         partly each, among the Shareholders of the Trust or the Series or Class
         according to their respective rights.

         (b) After termination of the Trust, Series or Class and distribution to
the  Shareholders as herein  provided,  a majority of the Trustees shall execute
and lodge  among  the  records  of the  Trust  and file  with the  Office of the
Secretary of the  Commonwealth of Massachusetts an instrument in writing setting
forth  the  fact of  such  termination,  and the  Trustees  shall  thereupon  be
discharged from all further  liabilities and duties with respect to the Trust or
the terminated Series or Class, and the rights and interests of all Shareholders
of the Trust or the terminated Series or Class shall thereupon cease.
<PAGE>

         Section 8.3. Amendment  Procedure.  (a) This Declaration may be amended
by a vote of the holders of a majority of the Shares outstanding and entitled to
vote or by any instrument in writing, without a meeting, signed by a majority of
the  Trustees  and  consented  to by the  holders  of a  majority  of the Shares
outstanding and entitled to vote.

         (b) The Trustees may amend this Declaration without the vote or consent
of  Shareholders  if they deem it necessary to conform this  Declaration  to the
requirements  of  applicable  Federal  or  state  laws  or  regulations  or  the
requirements  of the  regulated  investment  company  provisions of the Internal
Revenue  Code of 1986,  as amended,  or if requested or required to do so by any
Federal agency or by a state Blue Sky commissioner or similar official,  but the
Trustees  shall not be liable for failing so to do. The  Trustees may also amend
this  Declaration  without the vote or consent of  Shareholders  if they deem it
necessary  or desirable to change the name of the Trust or Series or to make any
other changes in the  Declaration  which do not  adversely  affect the rights of
Shareholders hereunder. Finally, the Trustees may amend this Declaration without
the vote or consent of Shareholders (i) to add to their duties or obligations or
surrender  any  rights  or  powers  granted  to them  herein;  (ii) to cure  any
ambiguity,   to  correct  or  supplement  any  provision  herein  which  may  be
inconsistent  with any other  provision  herein or to make any other  provisions
with respect to matters or questions  arising under this Declaration  which will
not be  inconsistent  with the  provisions  of this  Declaration;  and  (iii) to
eliminate or modify any provision of this Declaration which memorializes or sets
forth an  existing  requirement  imposed  by or under (a) any  Federal  or state
statute or any rule,  regulation or interpretation  thereof or thereunder or (b)
any rule,  regulation,  interpretation  or  guideline  of any  federal  or state
agency, now or hereafter in effect,  including without limitation,  requirements
set  forth  in the  1940  Act and the  rules  and  regulations  thereunder  (and
interpretations   thereof),   to  the  extent  any  change  in  applicable   law
liberalizes,  eliminates  or modifies  any such  requirements,  but the Trustees
shall not be liable for failure to do so.

         (c) No amendment  may be made under this Section 8.3 which would change
any rights with respect to any Shares of the Trust or Series or Class thereof by
reducing the amount payable  thereon upon  liquidation of the Trust or Series or
Class thereof or by  diminishing  or  eliminating  any voting rights  pertaining
thereto,  except  with the vote or consent of the holders of  two-thirds  of the
Shares of the Trust or such Series or Class  outstanding  and  entitled to vote.
Nothing  contained  in this  Declaration  shall  permit  the  amendment  of this
<PAGE>

Declaration to impair the exemption from personal liability of the Shareholders,
Trustees,  officers,  employees and agents of the Trust or to permit assessments
upon Shareholders.

         (d) A certificate signed by a majority of the Trustees setting forth an
amendment  and reciting that it was duly adopted by the  Shareholders  or by the
Trustees as aforesaid or a copy of the Declaration,  as amended, and executed by
a majority of the Trustees,  shall be conclusive evidence of such amendment when
lodged among the records of the Trust.

         Section 8.4. Merger  Consolidation and Sale of Assets. The Trust or any
Series thereof may merge or consolidate with any other corporation, association,
trust or other  organization or may sell, lease or exchange all or substantially
all of the Trust  Property or Trust  Property  allocated  or  belonging  to such
Series,  including its good will,  upon such terms and  conditions  and for such
consideration  when and as authorized at any meeting of Shareholders  called for
the purpose by the  affirmative  vote of the holders of two-thirds of the Shares
of the  Trust  or  such  Series  outstanding  and  entitled  to  vote,  or by an
instrument  or  instruments  in writing  without a meeting,  consented to by the
holders  of  two-thirds  of the  Shares of the Trust or such  Series;  provided,
however,  that,  if such  merger,  consolidation,  sale,  lease or  exchange  is
recommended  by the  Trustees,  the vote or written  consent of the holders of a
majority of the Shares of the Trust or such Series  outstanding  and entitled to
vote shall be  sufficient  authorization;  and any such  merger,  consolidation,
sale,  lease  or  exchange  shall  be  deemed  for all  purposes  to  have  been
accomplished under and pursuant to Massachusetts law.

         Section 8.5.  Incorporation.  The Trustees may cause to be organized or
assist  in  organizing  a  corporation  or  corporations  under  the laws of any
jurisdiction or any other trust, partnership,  association or other organization
to take  over all of the  Trust  Property  or the Trust  Property  allocated  or
belonging  to such  Series or to carry on any  business in which the Trust shall
directly or indirectly have any interest,  and to sell,  convey and transfer the
Trust  Property or the Trust  Property  allocated or belonging to such Series to
any such  corporation,  trust,  association or  organization in exchange for the
shares or securities  thereof or otherwise,  and to lend money to, subscribe for
the  shares  or  securities  of,  and  enter  into any  contracts  with any such
corporation,   trust,   partnership,   association  or   organization,   or  any
corporation,  partnership, trust, association or organization in which the Trust
or such Series holds or is about to acquire  shares or any other  interest.  The
Trustees  may also  cause a merger  or  consolidation  between  the Trust or any
successor thereto and any such corporation,  trust, partnership,  association or
other  organization if and to the extent permitted by law, as provided under the
<PAGE>

law then in effect.  Nothing  contained  herein  shall be construed as requiring
approval of  Shareholders  for the Trustees to organize or assist in  organizing
one  or  more  corporations,   trusts,   partnerships,   associations  or  other
organizations  and selling,  conveying or  transferring  all or a portion of the
Trust Property to such organization or entities.


                                   ARTICLE IX

                            REPORTS TO SHAREHOLDERS

         The Trustees shall at least semi-annually submit to the Shareholders of
each  Series a written  financial  report of the  transactions  of the Trust and
Series thereof, including financial statements which shall be certified at least
annually by independent public accountants.


                                   ARTICLE X

                                 MISCELLANEOUS

         Section 10.1.  Execution and Filing. This Declaration and any amendment
hereto  shall be filed in the office of the  Secretary  of The  Commonwealth  of
Massachusetts  and in such  other  places as may be  required  under the laws of
Massachusetts  and may also be filed or  recorded  in such  other  places as the
Trustees deem  appropriate.  Each  amendment so filed shall be  accompanied by a
certificate  signed and  acknowledged  by a Trustee stating that such action was
duly taken in a manner  provided  herein,  and  unless  such  amendment  or such
certificate sets forth some later time for the  effectiveness of such amendment,
such amendment  shall be effective upon its execution.  A restated  Declaration,
integrating  into a single  instrument all of the provisions of the  Declaration
which are then in effect and  operative,  may be executed from time to time by a
majority of the Trustees and filed with the  Secretary  of The  Commonwealth  of
Massachusetts.  A restated  Declaration  shall,  upon  execution,  be conclusive
evidence of all amendments  contained  therein and may thereafter be referred to
in lieu of the original Declaration and the various amendments thereto.

         Section  10.2.  Governing  Law.  This  Declaration  is  executed by the
Trustees and delivered in The Commonwealth of  Massachusetts  and with reference
to the laws thereof,  and the rights of all parties  hereto and the validity and
construction  of every  provision  hereof  shall  be  subject  to and  construed
according to the laws of said Commonwealth.
<PAGE>

         Section 10.3.  Counterparts.  This  Declaration  may be  simultaneously
executed  in  several  counterparts,  each of  which  shall be  deemed  to be an
original,  and such  counterparts,  together,  shall constitute one and the same
instrument,   which  shall  be  sufficiently  evidenced  by  any  such  original
counterpart.

         Section 10.4. Reliance by Third Parties. Any certificate executed by an
individual  who,  according to the records of the Trust  appears to be a Trustee
hereunder,  certifying  as  to  (a)  the  number  or  identity  of  Trustees  or
Shareholders,  (b) the due  authorization  of the execution of any instrument or
writing,  (c)  the  form  of  any  vote  passed  at a  meeting  of  Trustees  or
Shareholders,  (d) the fact that the number of Trustees or Shareholders  present
at any meeting or executing any written instrument satisfies the requirements of
this Declaration,  (e) the form of any By-laws adopted by or the identity of any
officers  elected by the  Trustees,  or (f) the  existence  of any fact or facts
which in any manner  relate to the  affairs of the  Trust,  shall be  conclusive
evidence as to the matters so certified in favor of any Person  dealing with the
Trustees and their successors.

         Section 10.5.  Provisions in Conflict with Law or Regulations.  (a) The
provisions  of  this  Declaration  are  severable,  and  if the  Trustees  shall
determine,  with the advice of legal counsel,  that any of such provisions is in
conflict with the 1940 Act, the regulated  investment  company provisions of the
Internal  Revenue Code of 1986, as amended,  or with other  applicable  laws and
regulations, the conflicting provision shall be deemed never to have constituted
a part of this Declaration; provided, however, that such determination shall not
affect any of the remaining  provisions of this Declaration or render invalid or
improper any action taken or omitted prior to such determination.

         (b) If any  provision  of this  Declaration  shall be held  invalid  or
unenforceable in any  jurisdiction,  such invalidity or  unenforceability  shall
attach only to such provision in such  jurisdiction  and shall not in any manner
affect such provision in any other  jurisdiction  or any other provision of this
Declaration in any jurisdiction.

         IN WITNESS WHEREOF,  the undersigned have executed this instrument this
7th day of December, 1993.

                             Shareholders' Meetings

SECTION 1. General. Voting powers and meetings of Shareholders shall be governed
by applicable  provisions of law, the  Declaration  of Trust and as  hereinafter
provided by these By-Laws.

SECTION 2.  Record  Date for  Meetings  and Other  Purposes.  For the purpose of
determining  the  Shareholders  who are entitled to notice of and to vote at any
meeting, or to participate in any distribution,  or for the purpose of any other
action,  the Trustees  may from time to time close the  transfer  books for such
period,  not  exceeding  thirty (30) days,  as the  Trustees may  determine;  or


                                      -3-
<PAGE>

without  closing the  transfer  books the  Trustees may fix a date not more than
sixty (60) days prior to the date of any meeting of Shareholders or distribution
or other  action as a record  date for the  determination  of the  persons to be
treated as Shareholders of record for such purposes.

SECTION 3. Notices.  Except as provided in the Declaration of Trust,  notices of
any  special  meeting of the  Shareholders  shall be given by the  Secretary  by
delivering or mailing,  postage prepaid, to each Shareholder entitled to vote at
said meeting,  a written or printed  notification of such meeting,  at least ten
days before the meeting,  to such address as may be registered with the Trust by
the Shareholder.

SECTION 4. Place of Meeting.  All special meetings of the Shareholders  shall be
held at the principal place of business of the Trust in Boston, Massachusetts or
at such other place in the United States as the Trustees may designate.

SECTION 5.  Quorum.  The presence in person or by proxy of the holders of record
of a majority of the shares of beneficial  interest  issued and  outstanding and
entitled  to vote  ("Outstanding  Shares")  shall  constitute  a quorum  for the
transaction  of any  business  at all  meetings  of the  Shareholders  except as
otherwise  provided by law, the  Declaration of Trust or these  By-Laws.  In the
absence of the required  quorum no business may be  transacted,  except that the
holders of a majority of the  Outstanding  Shares may  adjourn the meeting  from
time to time without notice other than announcement  thereat except as otherwise
required by these By-Laws,  until the holders of the requisite  amount of shares
of beneficial  interest shall be so present.  At any such  adjourned  meeting at
which the required quorum may be present,  any business may be transacted  which
might have been transacted at the meeting as originally notified.

SECTION  6.  Conduct  of  Shareholders'   Meetings.   At  each  meeting  of  the
Shareholders,  the Chairman of the Board of Trustees (if one has been designated
by the Board of Trustees), or if the Chairman of the Board of Trustees is absent
or unable to act, the President, or if the President is absent or unable to act,
a Vice President, or if none of them are present or able to act a chairman to be
elected at the meeting,  shall act as chairman of the meeting.  The Secretary of
the  Trust,  or if the  Secretary  is  absent or  unable  to act,  an  Assistant
Secretary,  or if none are present or able to act,  any person  appointed by the
chairman  of the  meeting,  shall act as  secretary  of the meeting and keep the
minutes thereof.

SECTION 7. Order of  Business.  The order of  business  at all  meetings  of the
Shareholders shall be as determined by the chairman of the meeting.


                                      -4-
<PAGE>

SECTION 8. Proxies.  At any meeting of  Shareholders,  any holder of Outstanding
Shares entitled to vote thereat may vote by proxy,  provided that no proxy shall
be voted at any  meeting  unless  it shall  have  been  placed  on file with the
Secretary, or with such other officer or agent of the Trust as the Secretary may
direct,  for verification prior to the time at which such vote shall be taken. A
proxy shall be deemed  signed if the  Shareholder's  name is placed on the proxy
(whether by manual  signature,  typewriting or telegraphic  transmission) by the
Shareholder or the Shareholder's  attorney-in-fact.  Proxies may be solicited in
the name of one or more  Trustees  or one or more of the  officers of the Trust.
Only Shareholders of record shall be entitled to vote. Each whole Share shall be
entitled to one vote as to any matter on which it is entitled by the Declaration
of Trust to vote and  fractional  Shares  shall be entitled  to a  proportionate
fractional vote. When any Share is held jointly by several  persons,  any one of
them may vote at any meeting in person or by proxy in respect of such Share, but
if more than one of them shall be present at such meeting in person or by proxy,
and such joint owners or their proxies so present  disagree as to any vote to be
cast,  such vote shall be received in respect of such Share. A proxy  purporting
to be executed by or on behalf of a  Shareholder  shall be deemed  valid  unless
challenged  at or prior to its  exercise,  and the burden of proving  invalidity
shall  rest on the  challenger.  If the holder of any such Share is a minor or a
person of unsound mind, and subject to  guardianship or the legal control of any
other person as regards the charge or management  of such Share,  he may vote by
his guardian or such other person  appointed  or having such  control,  and such
vote may be given in person or by proxy.

SECTION 9. Abstentions and Broker Non-Votes. Outstanding Shares represented at a
meeting in person or by proxy (including  Outstanding Shares which abstain or do
not vote with respect to one or more of any proposals  presented for Shareholder
approval)  will be  counted  for  purposes  of  determining  whether a quorum is
present at a meeting. Abstentions will be treated as Outstanding Shares that are
present  and  entitled  to vote  for  purposes  of  determining  the  number  of
Outstanding  Shares that are present  and  entitled to vote with  respect to any
particular  proposal,  but  will  not be  counted  as a vote  in  favor  of such
proposal.  If a broker or nominee  holding  Outstanding  Shares in "street name"
indicates on the proxy that it does not have discretionary  authority to vote as
to a particular  proposal,  those Shares will not be  considered  as present and
entitled to vote with respect to such proposal.

SECTION 10. Special Meetings. Special meetings of the Shareholders may be called
in accordance with the provisions of the Declaration of Trust. If the Secretary,
when ordered or requested to hold a special meeting of the Shareholders, refuses
or neglects for more than two days to call such special meeting, the Trustees or


                                      -5-
<PAGE>

the  Shareholders  so  requesting  may, in the name of the  Secretary,  call the
meeting by giving notice thereof in the manner  required when notice is given by
the Secretary.

SECTION  11.  Action  Without  Meeting.   Any  action  which  may  be  taken  by
Shareholders may be taken without a meeting if a majority of Outstanding  Shares
(or such larger  proportion  thereof as shall be required by law) consent to the
action in writing  and the  written  consents  are filed with the records of the
meetings of  Shareholders.  Such consents shall be treated for all purposes as a
vote taken at a meeting of Shareholders.

                               Trustees' Meetings

SECTION 1.  Meetings.  Meetings  of the  Trustees  shall be called  orally or in
writing by the Chairman or at his order or direction to the  Secretary or by any
two other  Trustees by written  request to the  Secretary,  and if the Secretary
when so requested  refuses or fails for more than one day to call such  meeting,
the Chairman, or such two other Trustees,  may in the name of the Secretary call
such meeting by giving due notice in the manner required when notice is given by
the Secretary.

SECTION 2. Quorum.  A majority of the Trustees shall constitute a quorum for the
transaction of business.

SECTION 3. Notices.  Except as otherwise provided,  notice of any meeting of the
Trustees  shall be given by the  Secretary to each  Trustee,  by mailing to him,
postage  prepaid,  addressed to him at his address as registered on the books of
the Trust or, if not so  registered,  at his last  known  address,  a written or
printed  notification  of such meeting at least three days before the meeting or
by  delivering  such notice to him at least two days before the  meeting,  or by
telephoning  him or by sending to him at least one day  before the  meeting,  by
prepaid telegram, addressed to him at his said registered address, if any, or if
he has no such  registered  address,  at his last known address,  notice of such
meeting.

SECTION 4. Place of Meeting.  All meetings of the Trustees  shall be held at the
principal place of business of the Trust in Boston, Massachusetts, or such other
place  within or without the  Commonwealth  as the person or persons  requesting
said  meeting to be called may  designate,  but any  meeting  may adjourn to any
other place.  Meetings may be held by means of a conference telephone circuit or
similar communications  equipment by means of which all persons participating in
the meeting can hear each other.


                                      -6-
<PAGE>

SECTION  5.  Special  Action.  When all the  Trustees  shall be  present  at any
meeting, however called, or wherever held, or shall assent to the holding of the
meeting without notice, or after the meeting shall sign a written assent thereto
on the record of such  meeting,  the acts of such  meeting  shall be valid as if
such meeting had been regularly held.

SECTION 6. Action by Consent.  Any action by the Trustees may be taken without a
meeting if a written consent thereto is signed by a majority of the Trustees and
filed with the  records  of the  Trustees'  meetings,  or by  telephone  consent
provided a majority of Trustees participate in any such telephone meeting.  Such
consent  shall be treated as a vote of the Trustees for all  purposes,  provided
however,  no such consent  shall be effective if the  Investment  Company Act of
1940  requires  that a  particular  action  be taken  only at a  meeting  of the
Trustees.


                                   ARTICLE VI

                         Shares of Beneficial Interest

SECTION 1.  Beneficial  Interest.  The beneficial  interest in the Trust and the
status of the owners  thereof  shall be  defined,  established  and  governed by
applicable provisions of law, the Declaration of Trust and as herein provided by
these By-Laws.

SECTION 2.  Transfers.  Shares may be  transferred  on the books of the Trust by
written request to the Trust or its transfer agent, with such proof of authority
or the  authenticity  of the  signature as the Trust or its  transfer  agent may
reasonably  require.  Except  as  may  be  otherwise  required  by  law,  by the
Declaration of Trust or by these  By-Laws,  the Trust shall be entitled to treat
the record holder of shares of beneficial  interest as shown on its books as the
owner of such shares for all  purposes,  including  the payment of dividends and
the right to vote with respect  thereto,  regardless of any transfer,  pledge or
other  disposition of such shares until the shares have been  transferred on the
books of the Trust in accordance with the requirements of these By-Laws.


                                  ARTICLE VII

                              Inspection of Books

             The Trustees shall from time to time determine  whether and to what
extent,  and at what times and places, and under what conditions and regulations
the  accounts  and  books  of the  Trust  or any of  them  shall  be open to the
inspection  of the  shareholders;  and no  shareholder  shall  have any right to
inspect any account or book or document of the Trust  except as conferred by law
or otherwise by the Trustees or by resolution of the shareholders.

Trust which shall contain in substance the following provisions:

            (a) The Trust will cause all securities and funds owned by the Trust

            draw upon any such account.

            (c) The Custodian(s)  shall release and deliver  securities owned by

                  representing  the same  aggregate  face  amount  or  number of
                  units;  provided that in any such case the new  securities are
                  to be delivered to the Custodian(s);

            (4)   To the broker selling the same for examination, in accord with
                  the "street delivery" custom;

            (5)   For  exchange  or  conversion  pursuant to any plan of merger,

            (d) The Custodian(s) shall pay out moneys of the Trust only upon the
            purchase of securities for the account of the Trust and the delivery

            of Trust or these  By-laws,  or for the  payment  of any  expense or
            liability incurred by the Trust;  provided that, in every case where
            payment  is made by the  Custodian(s)  in  advance of receipt of the
            securities purchased, the Custodian(s) shall be absolutely liable to
            the  Trust  for  such  securities  to  the  same  extent  as if  the
            securities had been received by the Custodian(s).

            (e)  The  Custodian(s)  shall  make  deliveries  of  securities  and
            payments of cash only upon written  instructions signed or initialed
            by such officer or officers or other agent or agents of the Trust as
            may be authorized to sign or initial such instructions by resolution
            of the Trustees; it being understood that the Trustees may from time
            to time  authorize a different  person or persons to sign or initial
            instructions for different purposes.

             The contract between the Trust and the Custodian(s) may contain any
such other provisions not inconsistent with the provisions of Section 3.6 of the
Declaration of Trust or with these By-laws as the Trustees may approve.

             Such  contract  shall be  terminable  by either  party upon written
notice to the other  within  such time not  exceeding  sixty (60) days as may be
specified in the  contract;  provided,  however,  that upon  termination  of the
contract or inability of the Custodian(s) to continue to serve, the Custodian(s)
shall,  upon written  notice of  appointment of another bank or trust company as
custodian,  deliver and pay over to such successor  custodian all securities and
moneys held by it for account of the Trust.  In such case,  the  Trustees  shall


                                      -9-
<PAGE>

promptly  appoint a  successor  custodian,  but in the event  that no  successor
custodian can be found having the required  qualifications and willing to serve,
it shall be the duty of the  Trustees  to call as promptly as possible a special
meeting of the  Shareholders  to  determine  whether  the Trust  shall  function
without  a  custodian  or shall be  liquidated.  If so  directed  by vote of the
holders of a majority of the outstanding  Shares, the Custodian(s) shall deliver
and pay over all property of the Trust held by it as specified in such vote.

             Such contract  shall also provide that,  pending  appointment  of a
successor  custodian  or a  vote  of  the  shareholders  specifying  some  other
disposition of the funds and property,  the Custodian(s) shall not deliver funds
and  property of the Trust to the Trust,  but it may  deliver  them to a bank or
trust  company  doing  business in Boston,  Massachusetts,  of its own selection
having aggregate capital,  surplus and undivided  profits,  as shown by its last
published report, of not less than $2,000,000 as the property of the Trust to be
held  under  terms  similar  to those on which  they were  held by the  retiring
custodian.

             Any  sub-custodian   employed  by  the  Custodian(s)   pursuant  to
authorization  to do so granted  by the Trust  pursuant  to  Section  3.6 of the
Declaration  of  Trust  shall be  required  to enter  into a  contract  with the
Custodian  containing  in substance the same  provisions  as those  described in
paragraphs (a) through (e) above,  except that any contract with a sub-custodian
performing  its  duties  outside  the  United  States  and its  territories  and
possessions,  may omit or limit any of such conditions,  provided that, any such
omission or limitation shall be expressly approved by a majority of the Trustees
of the Trust.

                              MANAGEMENT CONTRACT

         THIS AGREEMENT dated this 1st day of January, 1994 between Pioneer Bond
Fund, a  Massachusetts  business trust (the "Fund"),  and Pioneering  Management
Corporation, a Delaware corporation (the "Manager").

                                   WITNESSETH

         WHEREAS, the Fund is registered as an open-end,  management  investment
company under the  Investment  Company Act of 1940, as amended (the "1940 Act"),
and has filed with the Securities and Exchange  Commission (the  "Commission") a
registration  statement  (the  "Registration  Statement")  for  the  purpose  of
registering  its shares for public offering under the Securities Act of 1933, as
amended.

         WHEREAS,   the  Fund  currently   issues  one  series  of  shares  (the
"Portfolio"),

         WHEREAS,  the parties  hereto deem it  mutually  advantageous  that the
Manager  should be engaged,  subject to the  supervision  of the Fund's Board of
Trustees and officers, to manage the Fund,

         NOW,  THEREFORE,  in consideration of the mutual covenants and benefits
set forth herein, the Fund and the Manager do hereby agree as follows:

         1. (a) The Manager will regularly provide investment  research,  advice
and  supervision  and will furnish  continuously  an investment  program for the
Portfolio  consistent  with  the  investment  objectives  and  policies  of  the
Portfolio. The Manager will determine from time to time what securities shall be
purchased  for the  Portfolio,  what  securities  shall  be held or sold for the
Portfolio's  account and what  portion of the  Portfolio's  assets shall be held
uninvested as case,  subject always to the provisions of the Fund's  Declaration
of Trust,  By-Laws and its registration  statements under the 1940 Act and under
the  Securities  Act of 1933  covering  the  Fund's  shares,  as filed  with the
Securities and Exchange Commission,  and to the investment objectives,  policies
and  restrictions  of the  Portfolio,  as each of the same shall be from time to
time in effect, and subject,  further,  to such policies and instructions as the
Board of Trustees of the Fund may from time to time establish. To carry out such
determinations,  the Manager will exercise full  discretion and act with respect
to the  Portfolio  in the same  manner and with the same force and effect as the
Fund  itself  might  or  could  do with  respect  to  purchases,  sales or other


<PAGE>

transactions,  as  well  as  with  respect  to all  other  things  necessary  or
incidental  to the  furtherance  or  conduct of such  purchases,  sales or other
transactions.

                  (b) The Manager will, to the extent reasonably required in the
conduct of the business of the  Portfolio and upon the fund's  request,  furnish
research,  statistical  and advisory  reports upon the  industries,  businesses,
corporations  or securities as to which such requests shall be made,  whether or
not the  Portfolio  shall at the time have any  investment  in such  industries,
businesses, corporations or securities. The Manager will use its best efforts in
the  preparation  of such  reports and will  endeavor to consult the persons and
sources  believed  by it to have  information  available  with  respect  to such
industries, businesses, corporations or entities.

                  (c) The  Manager  will  maintain  all books and  records  with
respect to the Portfolio's  securities  transactions  required by sub-paragraphs
(b)(5),(6),(9)  and (10) and  paragraph  (f) of Rule  31a-1  under  the 1940 Act
(other than those  records being  maintained by the custodian or transfer  agent
appointed by the Fund with respect to the  Portfolio)  and preserve such records
for the periods  prescribed  therefor by Rule 31a-2 of the 1940 Act. The Manager
will also provide to the Board of Trustees such periodic and special  reports as
the Board may reasonably request.

         2. The Manager  recognizes  that the Fund may from time to time created
additional  investment  portfolios,  that  this  agreement  relates  only to the
management of the assets of the Portfolio, and that the management of the assets
of any additional  portfolio of the Fund are subject, or will be subject, to one
or more separate investment management agreements.

         3. (a) Except as otherwise  provided  herein,  the Manager,  at its own
expense, shall furnish to the Fund office space in the offices of the Manager or
in such other place as may be agreed upon from time to time,  and all  necessary
office  facilities,  equipment  and  personnel  for  managing  the  affairs  and
investments with respect to the Portfolio,  and shall arrange, if desired by the
Fund, for members of the Manager's  organization  to serve as officers or agents
of the Fund.

                  (b) The Manager  shall pay directly or reimburse the Fund for:
(i) the  compensation  (if any) of the  Trustees  who are  affiliated  with,  or
interested  persons of, the Manager  and all  officers of the Fund as such:  and
(ii)  all  expenses  not  hereinafter  specifically  assumed  by the Fund or the
Portfolio  where such expenses are incurred by the Manager or by the Fund or the


                                      -2-
<PAGE>

Portfolio  in  connection  with  the  management  of the  affairs  of,  and  the
investment and reinvestment of the assets of, the Portfolio.

                  (c) The Fund  shall  assume  and shall pay:  (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

compensation,  training and benefits; (ii) the charges and expenses of auditors;
(iii) the charges and expenses of any  custodian,  transfer  agent,  plan agent,

the  Portfolio;  (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  government  agencies;  (vi)  fees  and  expenses  involved  in
registering and maintaining registrations of the Fund and/or its shares with the
Commission,  state  or blue  sky  securities  agencies  and  foreign  countries,
including  the  preparation  of   Prospectuses   and  Statements  of  Additional
information for filing with the Commission;  (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 to the
Trustees;  (ix) distribution fees paid by the Fund in accordance with Rule 12b-1
promulgated  by the  Commission  pursuant to the 1940 Act; (x)  compensation  of
those Trustees of the Fund who are not affiliated with or interested  persons of
the  Manager,  the Fund (other than as  Trustees),  The Pioneer  Group,  Inc. or

certificates; and (xii) interest on borrowed money, if any.

                  (d) In  addition to the  expenses  described  in Section  3(c)
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.

         4. (a) The Fund  shall  pay to the  Manager,  as  compensation  for the
Manager's  services  hereunder,  a fee at the  rate of  0.50%  per  annum of the
Portfolio's  average daily monthly in arrears.  In the event of  termination  of
this Agreement,  the fee provided in this Section shall be computed on the basis
of the period  ending on the last  business  day on which this  Agreement  is in
effect subject to a pro rata  adjustment  based on the number of days elapsed in
the current month as a percentage of the total number of days in such month.


                                      -3-
<PAGE>

                  (b) If the  operating  expenses of the  Portfolio  in any year
exceed the  limits set by states  securities  laws or  regulations  in states in
which shares of the Portfolio are sold,  the amount payable to the Manager under
subsection  (a) above will be reduced (but not below $00, and the Manager  shall
make other arrangements  concerning expenses but, in each instance,  only as and
to the extent required by such laws or regulation.  If amounts have already been
advanced  to the Manager  under this  Agreement,  the  Manager  will return such
amounts to the Fund to the extent required by the preceding sentence.

                  (c) In addition to the foregoing, the Manager may from time to
time agree not to impose all or a portion of its fee otherwise payable hereunder
(in advance of the time such fee or a portion  thereof would  otherwise  accrue)
and/or  undertake  to pay or  reimburse  the  Fund for all or a  portion  of its
expenses not otherwise  required to be borne or  reimbursed by the Manager.  Any
such fee reduction or undertaking may be discontinued or modified by the Manager
at any time.

         5. The Manager  will not be liable for any error of judgment or mistake
of law or for any loss  sustained  by reason of the  adoption of any  investment
policy or the purchase, sale, or retention of any security on the recommendation
of the Manager,  whether or not such  recommendation  shall have been based upon
its own  investigation  and research or upon  investigation and research made by
any other individual, firm or corporation,  but nothing contained herein will be
construed to protect the Manager  against any liability to the Fund or Portfolio
or its  shareholders  by  reason  of  willful  misfeasance,  bad  faith or gross
negligence  in the  performance  of its  duties  or by  reason  of its  reckless
disregard of its obligations and duties under this Agreement.

         6. (a) Nothing in this  Agreement will in any way limit or restrict the
Manager or any of its officers,  directors, or employees from buying, selling or
trading in any securities for its or their own accounts or other  accounts.  The
Manager  may  act  as an  investment  advisor  to  any  other  person,  firm  or
corporation,  and may perform  management  and any other  services for any other
person, association,  corporation, firm or other entity pursuant to any contract
or  otherwise,  and take any action or do any thing in  connection  therewith or
related  thereto;  and no such  performance  of management or other  services or
taking of any such  action  or doing of any such  thing  shall be in any  manner
restricted  or  otherwise  affected  by any  aspect of any  relationship  of the
Manager  to or with the Fund or  deemed to  violate  or give rise to any duty or
obligation  of the Manager to the Fund except as  otherwise  imposed by law. The


                                      -4-
<PAGE>

Fund  recognizes  that  Manager,  in  effecting  transactions  for  its  various
accounts,  may not always be able to take or liquidate  investment  positions in
the same security at the same time and at the same price.

                  (b)  In  connection  with  purchases  or  sales  of  portfolio
securities for the account of the Portfolio,  neither the Manager nor any of its
Directors, officers or employees will act as a principal or agent or receive any
commission  except as permitted by the 1940 Act. The Manager  shall  arrange for
the placing of all orders for the purchase and sale of portfolio  securities for
the Portfolio's  account with brokers or dealers selected by the Manager. In the
selection of such brokers or dealers and the placing of such orders, the Manager
is directed at all times to seek for the Portfolio the most favorable  execution
and net price available except as described  herein.  It is also understood that
it is desirable for the Portfolio  that the Manager have access to  supplemental
investment and market  research and security and economic  analyses  provided by
brokers who may execute brokerage transactions at a higher cost to the Portfolio
than may  result  when  allocating  brokerage  to other  brokers on the basis of
seeking the most favorable price and efficient execution. Therefore, the Manager
is authorized  to place orders for the purchase and sale of  securities  for the
Portfolio's account with such brokers,  subject to review by the Fund's Trustees
from time to time with respect to the extent and  continuation of this practice.
It is understood that the services provided by such brokers may be useful to the
Manager in connection with its or its affiliates  services to other clients.  In
addition,  subject  to the  Manager's  obligation  to seek  the  most  favorable
execution  and net  price  available,  the  Manager  may  consider  the  sale of
Portfolio shares in selecting brokers and dealers.

                  (c) On occasions  when the Manager  deems the purchase or sale
of a  security  to be in the best  interest  of the  Portfolio  as well as other
clients,   the  Manager,  to  the  extent  permitted  by  application  laws  and
regulations,  may aggregate  the  securities to be sold or purchased in order to
obtain the best  execution  and lower  brokerage  commissions,  if any.  In such
event,  allocation  of the  securities  so  purchased  or  sold,  as well as the
expenses incurred in the transaction,  will be made by the Manager in the manner
it  considers  to be the  most  equitable  and  consistent  with  its  fiduciary
obligations to the Portfolio and to such clients.

         7. This Agreement  shall become  effective on the date hereof and shall
remain in force until May 31, 1995 and from year to year thereafter, but only so
long as its  continuance  is approved  annually by a vote of the Trustees of the
Fund voting in person,  including a majority of its Trustees who are not parties
to this  Agreement or interested  persons (as the term  (interested  persons" is
defined in the 1940 Act) of any such  parties,  at a meeting of Trustees  called


                                      -5-
<PAGE>

for the purpose of voting on such  approval  or by a vote of a "majority  of the
outstanding  voting  securities"  (as defined in the 1940 Act) of the Portfolio,
subject to the right of the Fund and the Manager to terminate  this  contract as
provided in Section 8 hereof.

         8. Either party hereto may, without  penalty,  terminate this Agreement
by vote of its Board of Directors or its Board of Trustees,  as the case may be,
or by vote of a "majority of its outstanding  voting  securities" (as defined in
the 1940 Act) of the Portfolio and the giving of 60 days' written  notice to the
other party.

         9. This  Agreement  shall  automatically  terminate in the event of its
assignment. For purposes of this Agreement, the term "assignment" shall have the
meeting given it by Section 2(a)(4) of the 1940 Act.

         10. The Manager is an independent contractor and not an employee of the
Fund or  Portfolio  for any purpose.  If any occasion  should arise in which the
Manager gives any advice to its clients  concerning the shares of the Portfolio,
the Manager  will act solely as  investment  counsel for such clients and not in
any way on behalf of the Fund or Portfolio.

         11. This Agreement  states the entire  agreement of the parties hereto,
and is intended to be the complete and exclusive  statement of the terms hereof.
It may not be added to or changed  orally,  and may not be modified or rescinded
except by a writing signed by the parties hereto and in accordance with the 1940
Act, when applicable.

         12. This Agreement and all  performance  hereunder shall be governed by
the laws of the Commonwealth of Massachusetts, which apply to contracts made and
to be performed in The Commonwealth of Massachusetts.

         13.  Any  term or  provision  of this  Agreement  which is  invalid  or
unenforceable in any jurisdiction  shall, as to such jurisdiction be ineffective
to the extent of such invalidity or  unenforceability  without rendering invalid
or  unenforceable  the  remaining  terms  or  provisions  of this  Agreement  or
affecting  the validity or  enforceability  of any of the terms or provisions of
this Agreement in any other jurisdiction.

         14.  The  parties  to this  Agreement  acknowledge  and agree  that all
liabilities arising hereunder,  whether direct or indirect, and of any and every
nature  whatsoever  shall be satisfied solely out of the assets of the portfolio
affected thereby and that no Trustee,  officer or holder of shares of beneficial


                                      -6-
<PAGE>

interest  of the  Fund  shall  be  personally  liable  for any of the  foregoing
liabilities.  The Fund's  Declaration of Trust, as amended from time to time, is
on  file  in the  Office  of the  Secretary  of  State  of The  Commonwealth  of
Massachusetts.  Such  Declaration  of Trust  describes in detail the  respective
responsibilities  and  limitations on liability of the Trustees,  officers,  and
holders of shares of beneficial interest.

         15.  This  Agreement  may be  executed  simultaneously  in two or  more
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together shall constitute one and the same instrument.

         IN WITNESS  WHEREOF,  the  parties  have caused  this  Agreement  to be
executed by their duly  authorized  officers and their seal to be hereto affixed
as of the day and year first above written.

                             UNDERWRITING AGREEMENT

         THIS UNDERWRITING  AGREEMENT,  dated this 10th day of July, 1990 by and
between Pioneer Bond Fund ("Pioneer") and Pioneer Funds  Distributor,  Inc. (the
"Underwriter").

                              W I T N E S S E T H

         WHEREAS,  Pioneer, a Massachusetts  business trust, is registered as an
open enc,  diversified,  management  investment  company  under  the  Investment
Company Act of 1940, as amended (the "1940 Act"),  and has filed a  registration
statement  (the  "Registered  Statement  ") with  the  Securities  and  Exchange
Commission  (the   "Commission")  for  the  purpose  of  registering  shares  of
beneficial  interest for public  offering  under the  Securities Act of 1933, as
amended;

         WHEREAS, the Underwriter, a corporation organized under the laws of the
Commonwealth of  Massachusetts  in 1989,  engages and is in good standing of the
National Association of Securities Dealers, Inc. (the "NASD");

         WHEREAS,  the parties  hereto deem it  mutually  advantageous  that the
Underwriter should act as Principal Underwriter, as defined in the 1940 Act, for
the sale to the public of the shares of  beneficial  interest of the  securities
portfolio of each series of Pioneer which the Trustees may  establish  from time
to time (individually, a "Portfolio and collectively, the Portfolios"); and

         WHEREAS,  the parties  hereto have executed an  Underwriting  Agreement
dated January 30, 1990, and wish by this Agreement to amend and supersede in its
entirety such prior Agreement.

         NOW,  THEREFORE,  in consideration of the mutual covenants and benefits
set forth herein, Pioneer and the Underwriter do hereby agree as follows:

         1. Pioneer does hereby grant to the Underwriter the right and option to
purchase shares of beneficial  interest of a Portfolio of Pioneer (the "Shares")
for  sale  to   investors   either   directly  or   indirectly   through   other
broker-dealers. The Underwriter is not required to purchase any specified number
of Shares,  but will purchase from Pioneer only a sufficient number of Shares as
may be necessary to fill unconditional  orders received from time to time by the
Underwriter from investors and dealers.

         2. The  Underwriter  shall  offer  Shares to the public at an  offering
price  based  upon  the net  asset  value of the  Shares,  to be  calculated  as
described in the Registration  Statement,  including the Prospectus,  filed with
<PAGE>

the Commission and in effect at the time of the offering,  plus sales charges as
approved by the Underwriter and the Trustees of Pioneer and as further  outlined
in Pioneer's  Prospectus.  The offering price shall be subject to any provisions
set forth in the  Prospectus  from time to time with  accumulation,  letters  of
intention,  exchangeability of shares, reinstatement privileges, net asset value
purchases by certain  persons and  reinvestments  of dividends  and capital gain
distributions.

         3.  In  the  case  of  all  Shares  sold  to  investors  through  other
broker-dealers,  a portion of applicable sales charges will be reallowed to such
broker-dealers  who are members of the NASD or, in the case of certain  sales by
banks or certain sales to foreign  nationals,  to brokers or dealers exempt from
registration  with the Commission.  The concession  reallowed to  broker-dealers
shall be set forth in a written sales  agreement and shall be generally the same
for broker-dealers providing comparable levels of sales and service.

         4. This  Agreement  may be  terminated by either party upon sixty days'
written notice.

         5. This  Agreement  shall  terminate on any  anniversary  hereof if its
terms and renewal have not been  approved by a majority vote of its Trustees who
are not  "interested  persons"  of the Trust and who have no direct or  indirect
financial  interest  in  the  operation  of  the  Underwriting   Agreement  (the
"Qualified  Trustees"),  at a meeting of the Trustees  called for the purpose of
voting on such  approval.  This  Agreement  may also be  terminated at any time,
without  payment of any penalty,  by Pioneer on 60 days'  written  notice to the
Underwriter,  or by  the  Underwriter  upon  similar  notice  to  Pioneer.  This
Agreement may also be terminated by a party upon five (5) days written notice to
the other party in the event that the Commission has issued an order or obtained
an injunction or other court order suspending  effectiveness of the Registration
Statement covering these shares of Pioneer.  Finally, this Agreement may also be
terminated  by  Pioneer  upon five (5) days  written  notice to the  Underwriter
provided either of the following events has occurred:  (i) the NASD has expelled
the  Underwriter or suspended its membership in that  organization;  or (ii) the
qualification,  registration, license or right of the Underwriter to sell shares
in a particular  state has been suspended or cancelled in a state in which sales
of the shares of Pioneer during the most recent 12 month period  exceeded 10% of
all shares of Pioneer sold by the Underwriter during such period.

         6. The  compensation for the services of the Underwriter as a principal
underwriter  under  this  Agreement  shall be (i) that part of the sales  charge
which is retained by the Underwriter  after allowance of discounts to dealers as


                                      -2-
<PAGE>

set forth in the Registration  Statement,  including the Prospectus,  filed with
the Commission and in effect at the time of the offering,  as amended,  and (ii)
those amounts payable to the Underwriter as reimbursement  of expenses  pursuant
to any  distribution  plan for Pioneer which may be in effect.  Noting contained
herein shall relieve Pioneer of any obligation under its management  contract or
any other contract with any affiliate of the Underwriter.

         7.  The  parties  to this  Agreement  acknowledge  and  agree  that all
liabilities  arising  hereunder,  whether  direct  or  indirect,  of any  nature
whatsoever, including without limitation, liabilities arising in connection with
any  agreement of Pioneer of its  Trustees as set forth herein to indemnify  any
party to this  Agreement or any other person,  if any, shall be satisfied out of
the  assets  of  Pioneer  and that no  Trustee,  officer  or holder of shares of
beneficial  interest  of  Pioneer  shall  be  personally  liable  for any of the
foregoing  liabilities.  Pioneer's Declaration of Trust, as amended from time to
time,  is on file in the Office of  Secretary  of State of the  Commonwealth  of
Massachusetts.  The  Declaration  of Trust  describes  in detail the  respective
responsibilities  and  limitations on liability of the Trustees,  officers,  and
holders of shares of beneficial interest of the Trustees,  officers, and holders
of shares of beneficial interest.

         8. This  Agreement  shall  automatically  terminate in the event of its
assignment (as that term is defined in the 1940 Act).

         9. In the event of any dispute  between  the  parties,  this  Agreement
shall be construed according to the laws of The Commonwealth of Massachusetts.

         10. This  Agreement is intended to amend and  supersede in its entirety
the existing Underwriting Agreement between the parties dated January 30, 1990.

         IN WITNESS  WHEREOF,  the parties hereto have caused this instrument to
be  executed  by their  duly  authorized  officers  and their  seal to be hereto
affixed as of day and year first above written.

AGREEMENT  made this 23rd day of December,  1991 between  PIONEER BOND FUND (the
"Fund") and Brown Brothers Harriman & Co. (the "Custodian");

WITNESSETH:  That in consideration of the mutual covenants and agreements herein
contained, the parties hereto agree as follows:

1.  Employment of Custodian:  The Fund hereby employs and appoints the Custodian
as a custodian for the term and subject to the provisions of this Agreement. The
Custodian  shall  not be under any duty or  obligation  to  require  the Fund to
deliver  to it any  securities  or funds  owned by the  Fund and  shall  have no
responsibility  or  liability  for or on account of  securities  or funds not so
delivered. The Fund will deposit with the Custodian copies of the Declaration of
Trust or Certificate of Incorporation  and By-Laws (or comparable  documents) of
the  Fund and all  amendments  thereto,  and  copies  of such  votes  and  other
proceedings  of the Fund as may be necessary  for or convenient to the Custodian
in the performance of its duties.

2. Powers and Duties of the Custodian  with respect to Property of the Fund held
by the Custodian:  Except for securities and funds held by any  Subcustodians or
held  by the  Custodian  through  a  non-U.S.  securities  depository  appointed
pursuant to the  provisions of Section 3 hereof,  the  Custodian  shall have and
perform the following powers and duties:

A. Safekeeping - To keep safely the securities and other assets of the Fund that
have been  delivered to the Custodian  and, on behalf of the Fund,  from time to
time to receive delivery of securities for safekeeping.

B. Manner of Holding Securities - To hold securities of the Fund (1) by physical
possession of the share  certificates  or other  instruments  representing  such
securities  in  registered  or  bearer  form,  or (2) in  book-entry  form  by a
Securities System (as said term is defined in Section 2U).

C. Registered Name;  Nominee - To hold registered  securities of the Fund (1) in
the name or any nominee name of the Custodian or the Fund, or in the name or any
nominee  name of any Agent  appointed  pursuant  to Section 6F, or (2) in street

certificate form,  so-called,  and in any case with or without any indication of
fiduciary  capacity,  provided  that  securities  are held in an  account of the
Custodian containing only assets of the Fund or only assets held as fiduciary or
custodian for customers.

D. Purchases - Upon receipt of Proper  Instructions,  as defined in Section X on
Page 16, insofar as funds are available for the purpose,  to pay for and receive
securities  purchased for the account of the Fund,  payment being made only upon
receipt of the securities (1) by the Custodian, or (2) by a clearing corporation
of a national  securities exchange of which the Custodian is a member, or (3) by
a Securities System.  However, (i) in the case of repurchase  agreements entered
into by the Fund,  the  Custodian  (as well as an Agent) may release  funds to a
Securities  System or to a Subcustodian  prior to the receipt of advice from the
Securities System or Subcustodian that the securities underlying such repurchase
agreement  have been  transferred  by book entry into the Account (as defined in
Section 2U) of the Custodian  (or such Agent)  maintained  with such  Securities
System or Subcustodian,  so long as such payment  instructions to the Securities
System or  Subcustodian  include a  requirement  that  delivery is only  against
payment for securities, (ii) in the case of foreign exchange contracts, options,
time deposits,  call account deposits,  currency  deposits,  and other deposits,
contracts or options  pursuant to Sections 2J, 2L, 2M and 2N, the  Custodian may
make payment therefor without  receiving an instrument  evidencing said deposit,
contract  or  option  so long  as  such  payment  instructions  detail  specific
securities to be acquired,  and (iii) in the case of securities in which payment
for the security and receipt of the instrument evidencing the security are under
generally  accepted trade  practice or the terms of the instrument  representing
the security  expected to take place in different  locations or through separate
parties,  such as commercial paper which is indexed to foreign currency exchange
rates,  derivatives and similar  securities,  the Custodian may make payment for
such  securities  prior to delivery  thereof in accordance  with such  generally
accepted  trade  practice  or the  terms  of the  instrument  representing  such
security.

E. Exchanges - Upon receipt of proper instructions,  to exchange securities held
by it for the account of the Fund for other  securities in  connection  with any

conversion  or other  event  relating  to the  securities  or the issuer of such
securities  and to deposit any such  securities in accordance  with the terms of
any  reorganization  or  protective  plan.  Without  proper  instructions,   the


                                      -2-

may surrender  securities  for transfer into a name or nominee name as permitted
in  Section  2C,  and  may  surrender  securities  for  a  different  number  of

principal amount of indebtedness, provided the securities to be issued are to be
delivered to the Custodian.

F. Sales of Securities - Upon receipt of proper  instructions,  to make delivery
of securities which have been sold for the account of the Fund, but only against
payment therefor (1) in cash, by a certified check,  bank cashier's check,  bank

with a clearing  corporation  of a  national  securities  exchange  of which the
Custodian  is a member,  or (3) by credit to the account of the  Custodian or an
Agent of the Custodian with a Securities System; provided,  however, that (i) in
the case of  delivery  of  physical  certificates  or  instruments  representing
securities, the Custodian may make delivery to the broker buying the securities,
against receipt  therefor,  for examination in accordance with "street delivery"
custom, provided that the payment therefor is to be made to the Custodian (which
payment  may be made by a  broker's  check)  or that such  securities  are to be
returned to the  Custodian,  and (ii) in the case of  securities  referred to in
clause  (iii) of the  last  sentence  of  Section  2D,  the  Custodian  may make
settlement,  including with respect to the form of payment,  in accordance  with
generally  accepted trade practice  relating to such  securities or the terms of
the instrument representing said security.

Subcustodian  or an Agent to surrender  securities to the depositary  used by an

written  receipt  therefor  adequately  describing  such  securities and written
evidence  satisfactory  to the  Subcustodian  or Agent that the  depositary  has
acknowledged  receipt of  instructions  to issue with respect to such securities
ADRs in the name of the Custodian,  or a nominee of the Custodian,  for delivery
to the  Custodian  in  Boston,  Massachusetts,  or at such  other  place  as the
Custodian may from time to time designate.

the name of the Fund on the Custodian's  books subject only to draft or order by
the  Custodian.  All funds  received by the Custodian from or for the account of
the Fund shall be  deposited in said  account(s).  The  responsibilities  of the
Custodian to the Fund for deposits  accepted on the  Custodian's  books shall be
that of a U. S. bank for a similar deposit.

If and when  authorized  by  proper  instructions,  the  Custodian  may open and
operate an additional  account(s) in such other banks or trust  companies as may


                                      -4-
<PAGE>

be designated by the Fund in such  instructions  (any such bank or trust company

Institution"),  provided that such account(s) (hereinafter collectively referred

account of the Fund and subject  only to the  Custodian's  draft or order.  Such
demand deposit  accounts may be opened with Banking  Institutions  in the United
States and in other  countries and may be denominated in either U. S. Dollars or
other currencies as the Fund may determine. All such deposits shall be deemed to
be portfolio  securities of the Fund and accordingly the  responsibility  of the
Custodian  therefore  shall be the same as and no greater  than the  Custodian's
responsibility in respect of other portfolio securities of the Fund.

M. Interest Bearing Call or Time Deposits - To place interest bearing fixed term
and call  deposits with such banks and in such amounts as the Fund may authorize

such deposit,  the accepting Banking Institution and other appropriate  details,
and shall retain such forms of advice or receipt evidencing the deposit, if any,
as may be forwarded to the Custodian by the Banking Institution.  Such deposits,
other than those placed with the Custodian, shall be deemed portfolio securities
of the Fund and the responsibilities of the Custodian therefor shall be the same
as those for demand deposit bank accounts  placed with other banks, as described
in Section K of this  Agreement.  The  responsibility  of the Custodian for such
deposits  accepted on the  Custodian's  books shall be that of a U.S. bank for a
similar deposit.

N.  Foreign  Exchange  Transactions  and  Futures  Contracts  Pursuant to proper
instructions,  to enter into foreign  exchange  contracts or options to purchase
and sell foreign  currencies for spot and future  delivery on behalf and for the

such Banking  Institutions,  including  the  Custodian  and  Subcustodian(s)  as
principals,  as approved and authorized by the Fund.  Foreign exchange contracts
and options other than those executed with the Custodian,  shall be deemed to be
portfolio  securities  of the Fund  and the  responsibilities  of the  Custodian
therefor shall be the same as those for demand deposit bank accounts placed with


                                      -5-

contracts  purchased or sold or any options on futures  contracts written by the
Fund, in accordance with the provisions of any agreement or agreements among any
of the Fund, the Custodian and such futures commission  merchant,  designated to
comply with the rules of the Commodity  Futures  Trading  Commission  and/or any
contract market, or any similar  organization or  organizations,  regarding such
margin  deposits;  and to release and/or transfer assets in such margin accounts
only in accordance with any such agreements or rules.

0. Stock Loans - Upon receipt of proper  instructions,  to deliver securities of
the Fund,  in  connection  with loans of securities by the Fund, to the borrower
thereof prior to receipt of the collateral, if any, for such borrowing, provided

the  Securities  System  require  that the  Securities  System may  deliver  the
securities to the borrower  thereof only upon receipt of the collateral for such
borrowing.

that the  payment is to be made in such form and manner and at such time,  which
may be after  delivery  by the  Custodian  of the  instrument  representing  the
security, as is in accordance with the terms of the instrument  representing the
security,  or  such  proper  instructions  as  the  Custodian  may  receive,  or
governmental  regulations,  the  rules  of  Securities  Systems  or  other  U.S.

conflict with or in any way contrary to any provisions of the Fund's Declaration
of Trust or Certificate of Incorporation or By-Laws (or comparable documents) or
votes or proceedings of the shareholders or Directors of the Fund. The Custodian
shall in no event be liable to the Fund and shall be indemnified by the Fund for
any violation which occurs in the course of carrying out  instructions  given by

<PAGE>

initialed on behalf of the Fund by one or more person or persons as the Board of
Directors  or  Trustees  of the Fund  shall  have from time to time  authorized,
provided,   however,  that  no  such  instructions  directing  the  delivery  of
securities or the payment of funds to an authorized  signatory of the Fund shall

may be  identified  by the Board of  Directors  or  Trustees  by name,  title or
position  and will  include at least one officer  empowered by the Board to name
other  individuals  who are authorized to give proper  instructions on behalf of
the Fund.  Telephonic or other oral  instructions  given by any one of the above
persons will be  considered  proper  instructions  if the  Custodian  reasonably
believes  them  to  have  been  given  by  a  person  authorized  to  give  such
instructions with respect to the transaction involved. Oral instructions will be
confirmed  by tested  telex or in writing in the manner set forth  above but the
lack of such  confirmation  shall  in no way  affect  any  action  taken  by the
Custodian  in reliance  upon such oral  instructions.  The Fund  authorizes  the
Custodian to tape record any and all telephonic or other oral instructions given
to the  Custodian by or on behalf of the Fund  (including  any of its  officers,
Directors,  Trustees,  employees or agents) and will deliver to the  Custodian a
similar authorization from any investment manager or adviser or person or entity
with similar responsibilities which is authorized to give proper instructions on
behalf of the Fund to the Custodian.  Proper instructions may relate to specific
transactions or to types or classes of  transactions,  and may be in the form of
standing instructions.

Proper  instructions  may  include  communications   effected  directly  between
electromechanical or electronic devices or systems, in addition to tested telex,

system.

establish and maintain on its books a segregated  account or accounts for and on
behalf of the Fund,  into which  account or  accounts  may be  transferred  cash
and/or securities of the Fund, including securities  maintained by the Custodian
pursuant to Section 2U hereof,  (i) in  accordance  with the  provisions  of any
agreement among the Fund, the Custodian and a broker-dealer registered under the
Securities  Exchange  Act of 1934 and a member of the  National  Association  of
Securities  Dealers,  Inc. (or any futures commission  merchant registered under
the Commodity Exchange Act) relating to compliance with the rules of the Options
Clearing  Corporation and of any registered national securities exchange (or the


                                      -10-
<PAGE>

Commodity Futures Trading Commission or any registered  contract market), or any
similar organization or organizations, regarding escrow or other arrangements in
connection with  transactions by the Fund, (ii) for purposes of segregating cash
or securities in connection with options purchased,  sold or written by the Fund
or commodity futures contracts or options thereon purchased or sold by the Fund,
(iii) for the purposes of compliance by the Fund with the procedures required by
Investment  Company Act Release No. 10666, or any subsequent release or releases
of the  Securities  and  Exchange  Commission  relating  to the  maintenance  of
segregated  accounts by registered  investment  companies,  and (iv) as mutually
agreed from time to time between the Fund and the Custodian.

3.  Powers and  Duties of the  Custodian  with  Respect  to the  Appointment  of
Subcustodians:  The Fund hereby  authorizes  and instructs the Custodian to hold
securities,  funds and other property of the Fund which are  maintained  outside
the United States at subcustodians  appointed pursuant to the provisions of this
Section  3 (a  "Subcustodian").  The  Fund  shall  approve  in  writing  (1) the
appointment of each  Subcustodian and the  subcustodian  agreement to be entered
into between such Subcustodian and the Custodian, and (2) if the Subcustodian is
organized under the laws of a country other than the United States,  the country
or countries in which the  Subcustodian is authorized to hold  securities,  cash
and other property of the Fund. The Fund hereby further authorizes and instructs
the  Custodian  and any  Subcustodian  to utilize such  securities  depositories
located  outside the United  States which are approved in writing by the Fund to
hold securities,  cash and other property of the Fund. Upon such approval by the
Fund,  the  Custodian  is  authorized  on  behalf  of the  Fund to  notify  each
Subcustodian  of its  appointment as such. The Custodian may, at any time in its
discretion,  remove any  Subcustodian  that has been  appointed as such but will
promptly notify the Fund of any such action.

Those  Subcustodians,  and the countries  where and the securities  depositories
through which they or the Custodian may hold securities, cash and other property
of the Fund  which the Fund has  approved  to date are set forth on  Appendix  A
hereto.  Such  Appendix  shall be  amended  from time to time as  Subcustodians,
and/or countries and/or securities  depositories are changed,  added or deleted.
The Fund shall be  responsible  for  informing  the  Custodian  sufficiently  in
advance of a proposed  investment which is to be held in a country not listed on
Appendix  A, in order that there shall be  sufficient  time for the Fund to give
the approval  required by the  preceding  paragraph and for the Custodian to put
the  appropriate  arrangements  in  place  with  such  Subcustodian,   including


                                      -11-
<PAGE>

negotiation  of a  subcustodian  agreement and  submission of such  subcustodian
agreement to the Fund for approval.

If the Fund shall have invested in a security to be held in a country before the
foregoing  procedures have been  completed,  such security shall be held by such
agent as the Custodian may appoint.  In any event, the Custodian shall be liable
to the  Fund  for the  actions  of such  agent  if and  only to the  extent  the
Custodian  shall have  recovered from such agent for any damages caused the Fund
by such  agent.  At the  request  of the Fund,  Custodian  agrees to remove  any
securities  held on  behalf  of the  Fund by such  agent,  if  practical,  to an
approved  Subcustodian.  Under such circumstances  Custodian will collect income
and respond to corporate actions on a best efforts basis.

With respect to securities and funds held by a Subcustodian,  either directly or
indirectly   (including  by  a  securities   depository  or  clearing   agency),
notwithstanding  any provision of this  Agreement to the  contrary,  payment for
securities  purchased  and  delivery  of  securities  sold may be made  prior to
receipt of the  securities or payment,  respectively,  and securities or payment
may be received in a form, in accordance with governmental regulations, rules of
securities  depositories  and clearing  agencies,  or generally  accepted  trade
practice in the applicable local market.

In the event that any Subcustodian  appointed pursuant to the provisions of this
Section 3 fails to perform any of its obligations under the terms and conditions
of the  applicable  subcustodian  agreement,  the  Custodian  shall use its best
efforts to cause such  Subcustodian  to perform such  obligations.  In the event
that the  Custodian is unable to cause such  Subcustodian  to perform  fully its
obligations  thereunder,  the Custodian  shall forthwith upon the Fund's request
terminate such Subcustodian in accordance with the termination  provisions under
the applicable  subcustodian  agreement and, if necessary or desirable,  appoint
another subcustodian in accordance with the provisions of this Section 3. At the
election  of the  Fund,  it shall  have  the  right to  enforce,  to the  extent
permitted by the  subcustodian  agreement and  applicable  law, the  Custodian's
rights against any such  Subcustodian for loss or damage caused the Fund by such
Subcustodian.

The Custodian  will not amend any  subcustodian  agreement or agree to change or
permit any  changes  thereunder  except upon the prior  written  approval of the
Fund.


                                      -12-
<PAGE>

The Custodian may, at any time in its discretion upon  notification to the Fund,
terminate  any  Subcustodian  of the Fund in  accordance  with  the  termination
provisions  under the  applicable  Subcustodian  Agreement,  and at the  written
request of the Fund, the Custodian will terminate any Subcustodian in accordance
with the termination provisions under the applicable Subcustodian Agreement.

If necessary or desirable,  the Custodian may appoint  another  subcustodian  to
replace a Subcustodian  terminated pursuant to the foregoing  provisions of this
Section  3,  such  appointment  to  be  made  upon  approval  of  the  successor
subcustodian by the Fund's Board of Directors or Trustees in accordance with the
provisions of this Section 3.

In the  event the  Custodian  receives  a claim  from a  Subcustodian  under the
indemnification  provisions of any subcustodian  agreement,  the Custodian shall
promptly give written notice to the Fund of such claim. No more than thirty days
after  written  notice  to the Fund of the  Custodian's  intention  to make such
payment, the Fund will reimburse the Custodian the amount of such payment except
in respect of any negligence or misconduct of the Custodian.

4. Assistance by the Custodian as to Certain  Matters:  The Custodian may assist
generally in the preparation of reports to Fund shareholders and others,  audits
of accounts, and other ministerial matters of like nature.

or of any of its or their  employees or from any failure of the Custodian or any
such  agent to  enforce  effectively  such  rights  as it may have  against  the
Securities  System.  At the  election  of the Fund,  it shall be  entitled to be
subrogated to the rights of the Custodian  with respect to any claim against the
Securities  System  or any  other  person  which  the  Custodian  may  have as a
consequence of any such loss or damage to the Fund if and to the extent that the
Fund has not been made whole for any such loss or damage.

C. Liability of the Custodian with respect to Subcustodians  The Custodian shall
be liable to the Fund for any loss or damage to the Fund caused by or  resulting
from the acts or  omissions  of any  Subcustodian  to the extent  that under the

Subcustodian  (or in the subcustodian  agreement  between a Subcustodian and any
secondary Subcustodian), the Subcustodian (or secondary Subcustodian) has failed

transmitting  any  instructions  received  by it from  the  Fund and for its own
negligence in connection with the delivery of any securities or funds held by it
to any Subcustodian.

D. Standard of Care;  Liability;  Indemnification  - The Custodian shall be held
only to the  exercise of  reasonable  care and  diligence  in  carrying  out the
provisions of this  Agreement,  provided that the Custodian shall not thereby be
required to take any action which is in contravention of any applicable law. The
Fund agrees to indemnify  and hold  harmless the Custodian and its nominees from

<PAGE>

all claims and liabilities (including counsel fees) incurred or assessed against
it or its nominees in connection with the performance of this Agreement,  except
such as may arise from its or its nominee's  breach of the relevant  standard of
conduct  set  forth  in  this   Agreement.   Without   limiting  the   foregoing
indemnification  obligation  of the  Fund,  the Fund  agrees  to  indemnify  the
Custodian and any nominee in whose name  portfolio  securities or other property

may incur by reason of taxes  assessed to the Custodian or such nominee or other
costs,  liability or expense incurred by the Custodian or such nominee resulting

It is also  understood  that the  Custodian  shall  not be  liable  for any loss
involving any  securities,  currencies,  deposits or other property of the Fund,
whether maintained by it, a Subcustodian,  a securities depository,  an agent of
the Custodian or a Subcustodian,  a Securities System, or a Banking Institution,
or for any loss arising from a foreign currency  transaction or contract,  where
the loss  results  from a Sovereign  Risk or where the entity  maintaining  such
securities,  currencies,  deposits or other  property  of the Fund,  whether the
Custodian, a Subcustodian, a securities depository, an agent of the Custodian or
a  Subcustodian,  a Securities  System or a Banking  Institution,  has exercised
reasonable care  maintaining such property or in connection with the transaction
involving  such  property.  A  "Sovereign  Risk"  shall  mean   nationalization,
expropriation,  devaluation,  revaluation,  confiscation, seizure, cancellation,
destruction  or similar  action by any  governmental  authority,  de facto or de
jure;  or  enactment,  promulgation,  imposition  or  enforcement  by  any  such
governmental  authority  of currency  restrictions,  exchange  controls,  taxes,
levies  or  other  charges  affecting  the  Fund's  property;  or  acts  of war,
terrorism,  insurrection  or  revolution;  or any other act or event  beyond the
Custodian's control.

E.  Reimbursement  of  Advances - The  Custodian  shall be  entitled  to receive
reimbursement  from the Fund on demand, in the manner provided in Section 7, for
its cash disbursements, expenses and charges (including the fees and expenses of
any Subcustodian or any Agent) in connection with this Agreement,  but excluding
salaries and usual overhead expenses.

F.  Security  for  Obligations  to  Custodian  - If the Fund shall  require  the
Custodian to advance cash or  securities  for any purpose for the benefit of the

(collectively,  an "Advance"),  or if the Custodian or any nominee thereof shall
incur or be  assessed  any  taxes,  charges,  expenses,  assessments,  claims or
liabilities in connection with the performance of this Agreement (collectively a
"Liability"),  except such as may arise from its or such nominee's breach of the
relevant standard of conduct set forth in this Agreement, then in such event any
property  at any time held for the  account  of the Fund by the  Custodian  or a
Subcustodian  shall be security for such  Advance or  Liability  and if the Fund
shall fail to repay or indemnify the Custodian promptly,  the Custodian shall be
entitled  to utilize  available  cash and to  dispose  of the  Fund's  property,
including  securities,  to the  extent  necessary  to  obtain  reimbursement  or
indemnification.

G.  Appointment  of  Agents  - The  Custodian  may at any  time or  times in its
discretion  appoint (and may at any time remove) any other bank or trust company
as its agent (an "Agent") to carry out such of the  provisions of this Agreement
as the  Custodian  may from time to time  direct,  provided,  however,  that the
appointment of such Agent (other than an Agent  appointed  pursuant to the third
paragraph  of  Section  3)  shall  not  relieve  the  Custodian  of  any  of its
responsibilities under this agreement.

such proxies,  powers of attorney or other  instruments as may be reasonable and
necessary or desirable in connection  with the  performance  by the Custodian or

Custodian.

         Re:      Post-Effective Amendment No. 23 to Registration
                  Statement on Form N-1A (File Nos. 2-62436
                  and 811-2864)

Ladies and Gentlemen:

         Pioneer  Bond Fund (the  "Trust")  is a  Massachusetts  business  trust
organized  under a written  Amended  and  Restated  Declaration  of Trust  dated
December 7, 1993, and as further  amended on December 7, 1993 (the  "Declaration
of Trust").  The beneficial interests thereunder are represented by transferable
shares of beneficial interest without par value.

         The Trustees of the Trust have the powers set forth in the  Declaration
of Trust,  subject to the terms,  provisions  and conditions  therein  provided.
Pursuant to Article V, Section 5.1 of the  Declaration  of Trust,  the number of
shares of beneficial  interest  authorized to be issued under the Declaration of
Trust is unlimited and the Trustees are authorized to divide the shares into one
or more series of shares and one or more classes  thereof as they deem necessary
or desirable.  Pursuant to Article V, Section 5.4 of the  Declaration  of Trust,
the  Trustees  may  issue  shares  of any  series  for such  amount  and type of
consideration,  including  cash or property,  and on such terms as they may deem
advisable without action or approval of the shareholders.

         We understand  that you are about to register  under the Securities Act
of 1933,  as amended,  67,232 shares of  beneficial  interest by  Post-Effective
Amendment No. 23 to the Trust's Registration Statement.
<PAGE>
Pioneer Bond Fund

Page 2


         We have examined the Declaration of Trust, the By-laws,  resolutions of
the Board of Trustees, minutes of the meetings of the Board of Trustees relating
to the authorization and issuance of shares of beneficial  interest of the Trust
and such other  documents  as we have deemed  necessary or  appropriate  for the
purposes of this opinion,  including,  but not limited to, originals,  or copies
certified or otherwise identified to our satisfaction,  of such documents, Trust
records and other  instruments.  In our examination of the above  documents,  we
have  assumed  the  genuineness  of  all  signatures,  the  authenticity  of all
documents submitted to us as originals,  the conformity to original documents of
all  documents   submitted  to  us  as  certified  or  photostatic  copies,  the
authenticity of the originals of such latter  documents and the legal competence
of each individual executing any documents.

         For purposes of this opinion  letter,  we have not made an  independent
review of the laws of any state or jurisdiction  other than The  Commonwealth of
Massachusetts   and  express  no  opinion  with  respect  to  the  laws  of  any
jurisdiction other than the laws of The Commonwealth of Massachusetts.  Further,
we  express no opinion  as to  compliance  with any state or federal  securities
laws, including the securities laws of The Commonwealth of Massachusetts.

         Our opinion below, as it relates to the non-assessability of the shares
of the  Trust,  is  qualified  to  the  extent  that  under  Massachusetts  law,
shareholders of a Massachusetts  business trust,  such as the Trust, may be held
personally  liable for the obligations of such Trust.  In this regard,  however,
please be advised that the Declaration of Trust disclaims  shareholder liability
for acts or obligations of the Trust and requires that notice of such disclaimer
be given in each note, bond, contract, certificate or undertaking made or issued
by or on behalf of the  Trust.  Also,  the  Declaration  of Trust  provides  for
indemnification  out  of  Trust  property  for  all  loss  and  expense  of  any
shareholder held personally  liable solely by reason of his being or having been
a shareholder  of the Trust;  provided,  however,  that no Trust property may be
used to indemnify  any  shareholder  of any series of the Trust other than Trust
property allocated or belonging to that series.

         We are of the opinion that all necessary Trust action  precedent to the
issue of the shares of beneficial  interest of the Trust  comprising  the shares
covered by  Post-Effective  Amendment No. 23 to the  Registration  Statement has
been duly taken, and that all such shares may be legally and validly issued, and
when sold will be fully paid and non-assessable by the Trust upon receipt by the
Trust or its agent of consideration  therefor in accordance with terms described
in the Trust's Declaration of Trust and the Registration  Statement,  subject to
compliance with the Securities Act of 1933, as amended,  the Investment  Company
Act of 1940, as amended,  and the applicable  state laws  regulating the sale of
securities.

         We consent to your filing this opinion with the Securities and Exchange
Commission as an Exhibit to Post-Effective  Amendment No. 23 to the Registration
Statement.  Except as provided in this paragraph, this opinion may not be relied
upon by, or filed with, any other parties or used for any other purpose.

                                            Very truly yours,

Agreement");

         WHEREAS,  the Fund 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 Shares in connection  with the offering of

         WHEREAS,  the Board of Trustees of the Fund, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it

this paragraph 2 and,  without  limiting the  generality of the  foregoing,  the
initial  categories  of such  expenses  shall be (i) a service fee to be paid to
qualified  broker-dealers  in an amount not to exceed .25 of 1% per annum of the
Fund's daily net assets;  (ii)  reimbursement  to PFD or  Pioneering  Management
Corporation  for its  expenditures  for  broker-dealer  commissions and employee
compensation on certain sales of the Fund's shares with no initial sales charge;
and (iii)  reimbursement  to PFD for  expenses  incurred  providing  services to
shareholders  and supporting  broker-dealers  and other  organizations,  such as
banks  and trust  companies,  in their  effort to  provide  such  services  (any
addition of such  categories  shall be subject to the approval of the  Qualified
Trustees,  as defined below, of the Fund). Such reimbursement  shall be paid ten
(10) days  after the end of the month or  quarter,  as the case may be, in which
such expenses are  incurred.  Reimbursable  expenses  will not carryover  beyond
twelve months from the time they are incurred.  The Fund  acknowledges  that PFD
will  charge a sales load in  connection  with sales of such shares and that PFD
will reallow to Dealers all or a portion of such sales load, as described in the
Fund's  Prospectus from time to time.  Nothing  contained  herein is intended to
have any affect  whatsoever on PFD's ability to charge any such sales load or to
reallow all or any portion thereof to Dealers.

         3. The Fund  understands  that  agreements  between PFD and Dealers may
provide for payment of fees to Dealers in connection with the sale of Shares and
the  provision  of services to  shareholders  of the Fund.  Nothing in this Plan
shall be construed as requiring the Fund to make any payment to any Dealer or to


                                      -2-
<PAGE>

have any  obligations  to any Dealer in connection  with services as a dealer of
the 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 Fund.

         4. Nothing herein contained shall be deemed to require the Fund to take
any action  contrary to its  Declaration  of Trust of 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  Fund's  Board  of  Trustees  of  the
responsibility for and control of the conduct of the affairs of the Fund.

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

         6. This 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 Fund and a majority of the  Qualified  Trustees.
This Plan shall expire on September 30 of any year,  beginning on September  30,
1991,  in which such approval is not obtained.  In the event of  termination  or
non-continuance  of this  Plan,  the Fund has  twelve  months to  reimburse  any
unreimbursed   expense  which  is  incurred   prior  to  such   termination   or
non-continuance.

         7.  This  Plan may be  amended  at any time by the  Board of  Trustees,
provided that this Plan may not be amended to increase materially the limitation
on the annual percentage of average of holders of a "majority of the outstanding
voting  securities"  of the Fund and may not be  materially  amended in any case
without a vote of a majority of both the  Trustees and the  Qualified  Trustees.
Any  amendment  of this  Plan to  increase  or  modify  the  expense  categories
initially  designated  by the  Trustees in  paragraph 2 above shall only require
approval  of a majority  of the  Trustees  and the  Qualified  Trustees  if such
amendment  does not include an increase in the expense  limitation  set forth in
paragraph  1  above.  This  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 the Fund.


                                      -3-
<PAGE>

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

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

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

         11. The Fund shall  preserve  copies of this Plan,  and each  agreement
related hereto and each report referred to in paragraph 8 hereof  (collectively,
the "Records"),  for a period of not less that 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.

         12. This Plan shall be  construed  in  accordance  with the laws of the
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

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

         CLASS B DISTRIBUTION  PLAN,  dated as of April 4, 1994, of PIONEER BOND
FUND, a Massachusetts business trust (the "Fund").

                                   WITNESSETH

         WHEREAS,  the Fund 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 Fund intends to distribute shares of beneficial  interest
(the "Class B Shares") of the Fund 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 B  distribution  plan (the "Class B Plan") as a plan
of distribution pursuant to such Rule;

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

         WHEREAS, the Fund has entered into an underwriting agreement (in a form
approved  by the Fund'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 Fund in connection with the offering and distribution of Class B
Shares (the "Underwriting Agreement");

         WHEREAS,  the Fund 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 B Shares in  connection  with the
offering of Class B Shares, (b) PFD may compensate any Dealer that sells Class B
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 B
shares, its profits or any other source available to it;

         WHEREAS,  the Fund  recognizes  and agrees that PFD may impose  certain
deferred  sales charges in connection  with the  repurchase of Class B shares by
the Fund,  and PFD may retain (or receive from the Fund, as the case may be) all
such deferred sales charges; and
<PAGE>

         WHEREAS,  the Board of Trustees of the Fund, in considering whether the
Fund  should  adopt  and  implement  this  Class  B  Plan,  has  evaluated  such
information  as it deemed  necessary to an informed  determination  whether this
Class B 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  Fund for such  purposes,  and has  determined  that  there is a  reasonable
likelihood  that the  adoption  and  implementation  of this  Class B Plan  will
benefit the Fund and its Class B shareholders;

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

         1. (a) The Fund 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 Fund's  Class B
         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 shall be .75% of the average daily net assets of
         the Fund attributable to 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 Fund's  Class B shares;  printing  of reports  and
         prospectuses  for other than existing  shareholders;  and  preparation,
         printing  and   distribution   of  sales   literature  and  advertising
         materials.

            (d) The  amount  of  compensation  paid  for  personal  and  account
         maintenance  services and expenses  shall be .25% of the average  daily
         net  assets  of  the  Fund   attributable  to  such  year.  As  partial
         consideration for personal services and/or account maintenance services


                                      -2-
<PAGE>

         provided by PFD to the Class B shares, PFD shall be entitled to be paid
         any fees  payable  under this clause (d) with respect to Class B 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 B  shares  or their
         accounts or who provide similar  services not otherwise  provided by or
         on behalf of the Fund.

            (f) PFD may impose certain deferred sales charges in connection with
         the  repurchase  of Class B shares by the Fund and PFD may  retain  (or
         receive  from the Fund 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 Fund 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.

         2. The Fund  understands  that  agreements  between PFD and Dealers may
provide  for payment of fees to Dealers in  connection  with the sale of Class B
Shares and the  provision of services to  shareholders  of the Fund.  Nothing in
this Class B Plan shall be construed  as requiring  the Fund 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 B 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 Fund.

         3. Nothing herein contained shall be deemed to require the Fund 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 Fund's  Board of Trustees of the  responsibility  for and control of
the conduct of the affairs of the Fund.

         4. This Class B Plan shall become  effective upon approval by a vote of
the Board of  Trustees  and a vote of a  majority  of the  Trustees  who are not

interest in the  operation of the Class B Plan or in any  agreements  related to
the Class B Plan (the "Qualified Trustees"),  such votes to be cast in person at
a meeting called for the purpose of voting on this Class B Plan.

         5. This Class B 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 Fund and a majority of the Qualified Trustees.
If such annual approval is not obtained, this Class B Plan shall expire on April
30, 1995.

         6.  This  Class B Plan  may be  amended  at any  time by the  Board  of
Trustees,  provided  that  this  Class B 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  Class B voting  securities"  of the Fund 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 B 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 B of the Fund.

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

         8. While this Class B 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 Fund.

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

         10.  The Fund  shall  preserve  copies of this  Class B 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.
